Features of Xuye Machinery’s fully automatic egg tray production line

Due to the pollution problem of plastic packaging containers, countries around the world have consistently emphasized environmental protection in recent years, and the importance of paper packaging containers has been increasingly recognized by people. Pulp molded egg trays, fruit trays and other trays have become ideal products for egg and fruit product packaging due to their good protective performance and low price. The fully automatic egg tray production line can be used to produce egg trays, fruit trays and other products. High efficiency, high yield, energy saving and speed increase, it is currently the leading egg tray production line equipment in China. So, what is the working principle of this kind of egg tray equipment for tray products? The fully automatic egg tray production line system integrates pulping, molding, drying and stacking, and automatically and continuously completes each process. 1. The pulping system mixes waste paper such as old newspapers, magazines, cartons, etc. into a certain concentration of pulp for molding through processes such as crushing, screening, and adding chemical additives. 2. The molding system uses vacuum to make the pulp evenly adhere to the special molding mold to form a wet blank product, which is then transferred to the...

Production method of rotary egg tray machine

 The production of egg trays requires the use of rotary egg tray machines, which are widely used in life and have a large demand for quantity. However, many people do not understand the use and working principle of rotary egg tray machines. This is actually because everyone does not understand this rotary egg tray machine. When we understand it, we will find that the rotary egg tray machine is very convenient when it is used. Motion control technology has developed very rapidly in China, but the development momentum of the rotary egg tray machine industry seems to be weak. The role of motion control products and technologies in packaging machinery is mainly to achieve precise position control and strict speed synchronization requirements. They are mainly used in loading and unloading, conveying, marking, stacking, unloading and other processes. Turn the host to observe the matching gap between the forming mold and the transfer mold, whether the gap between the forming mold and the transfer mold is consistent, and observe the four corners of the mold contact surface. The gap is 1 mm for the best matching gap. If the selected host is a multi-faceted forming machine, turn it to see whether...

What are the advantages of egg tray machines

 The molding quality of rotary egg tray machines can be categorized as good, poor, or very poor, with the classification standard being the degree of homogenization of the egg trays or the uniform distribution of fibers. A new type of pulp egg tray machine is a general term for pulp egg tray machines used for long-distance egg transportation. It mainly consists of a forming machine, a hydraulic pulper, a vacuum dewatering machine, an air compressor, and a drying oven. Today, let’s take a look at the advantages of the new type of pulp egg tray machine. The primary drying energy source used for pulp selection production in the new pulp egg tray machine can be diesel or natural gas. Customers can choose the more cost-effective option based on the local prices of these energy sources. Coal or heavy oil can also be used, but this would require the use of steam or thermal boilers, which would increase the equipment’s investment cost and footprint. The rotary egg tray machine mainly comprises the pulp molding system, pulp forming system, pulp drying system, and auxiliary systems. The storage and flow of pulp in the pulping system, as well as the molding structure and...

The main purpose of egg tray machine

Egg trays are typically used to hold eggs such as chicken and duck eggs. Their primary functions are shock absorption and ease of transport and handling. Based on the manufacturing material, egg trays can be divided into pulp egg trays and plastic egg trays. Depending on the number of eggs they hold, they can be classified as single egg trays or carton egg trays. Pulp egg trays are mostly made from recycled paper pulp through molding machines. Due to their simple manufacturing process, low cost, and environmental friendliness, they are referred to as “green” packaging and are the most common type of egg trays we use daily. The machines that produce egg trays are called egg tray machines, which are used to manufacture pulp egg trays for long-distance transportation of eggs. The main components of egg tray machines include molding machines, hydraulic pulpers, vacuum dewatering machines, air compressors, and drying ovens. Molding machines are divided into four types: reciprocating, single-side suction, four-side rotating, and eight-side rotating. Hydraulic pulpers are categorized into vertical and horizontal types. Vacuum dewatering machines are classified into three types: Roots vacuum pumps, water ring vacuum pumps, and Roots blowers. Air compressors used are piston air compressors....

How to ensure the quality of egg tray production equipment

  The temperature in the drying channel of the egg tray machine can usually reach 105-200 degrees Celsius. No matter which drying equipment is selected, the equipment itself is required to have a good insulation layer to prevent heat loss, and the structure of the equipment should be able to ensure that the temperature of the internal components is uniform. There are currently two main methods for obtaining hot air. One is to directly generate hot air by burning in a hot air furnace. The other is to use steam to generate hot air through heat exchange and air heat exchange. Hot air is used as a drying medium in the drying channel, and the heat source can be coal, fuel oil or natural gas. Therefore, to ensure the quality of egg tray production equipment, special attention should be paid to raw materials at this time. Only by ensuring the quality and safety of raw materials can you finally get the product and make full use of them. Most people do not guarantee the safety of raw materials, which may lead to unqualified overall quality. It is necessary to pay extra attention to that since the egg tray will shape...

The relationship between mold and finished product

  Pulp molding utilizes molding molds to shape pulp slurry into paper molded products, with molds being crucial to this technique. It is commonly used to produce disposable fast food boxes, bowls, and trays, which have simple shapes and utilize molds and products that are somewhat standardized. However, for industrial packaging and other applications, pulp molding involves larger variations in product dimensions and more complex and diverse shapes, necessitating bespoke molds for each design. Therefore, mold design and production are integral throughout the product manufacturing process.   The molding process for pulp molded products differs significantly from that of rubber and plastic products in the mold cavity. Pulp molded products are formed using a slurry containing approximately 1% fiber in a water solution. During forming, most of the water must be removed, requiring molds to be meshed. The molding process involves the slurry depositing a certain thickness onto a mesh mold, necessitating formation on the surface of a single convex or concave mesh mold. As the product forms, it also acts as a filtering process, with thicker sections decreasing filtration performance and forming speed. Thus, regardless of the complexity of the product shape, the thickness of pulp molded products uniformly...
