Description

Processing device and processing technology of high-strength stretch stretch film

technical field

The invention relates to a processing method of a plastic film, in particular to a processing device and a processing technology of a high-strength stretch stretch film.

Background technique

Stretch film, also known as stretch film, is mainly used in conjunction with pallets to package scattered goods in place of small containers. Because it can reduce the cost of bulk cargo transportation and packaging by more than 30%, it is widely used in the packaging of various products such as hardware, minerals, chemicals, medicine, food, machinery, etc.; in the field of warehouse storage, it is also widely used abroad. Stretch film tray packaging for three-dimensional storage and transportation to save space and land occupation.

At present, the stretch film on the market mainly uses PE as the raw material. Using this material to manufacture the stretch film has high production cost, which is not conducive to the long-term development of the enterprise; and the current stretch film production process produces a lot of waste, 100 tons. The material can only produce 70-80 tons of stretch film, and the remaining 20-30 tons are all wasted as waste, which has caused a large waste in the production of the enterprise.

Contents of the invention

The purpose of the present invention is to provide a high-strength stretch stretch film processing device and processing technology with reasonable structure design, low production cost and effective use of waste in order to solve the shortcomings of the above-mentioned technologies.

In order to achieve the above purpose, a processing device for high-strength stretch stretch film designed by the present invention includes a feeding mechanism, a heating box, and a forming mechanism. The feeding mechanism includes three feeding bins, which are respectively good material feeding bins , secondary material feeding bin, recycled material feeding bin, the bottom of the recycled material feeding bin is connected with the secondary material feeding bin; the good material feeding bin and the bottom of the secondary material feeding bin are each connected with a heating box, and the heating The other end of the box is provided with an intercommunicating mixer, and the bottom of the mixer is connected with a die head; the bottom of the die head is provided with a forming mechanism, and the forming mechanism includes a frame, a control box, two a roller, a plurality of guide rollers, and a blanking roller, one end of the frame is provided with two rollers, and the outermost roller corresponds to the die head, cooling water is provided in the roller, and the frame The other side of the blanking roller is provided with a blanking roller, and the two ends of the frame outside the blanking roller are provided with an outwardly extending empty groove, and the outermost end of the empty groove is provided with a groove, and the empty groove Both ends of the charging roller are provided with clamps, the two ends of the charging roller are set in the clamps on the empty groove, the two ends of the charging roller are arranged in the empty groove, and one end of the charging roller is connected to a cylinder. A plurality of guide rollers are provided between the blanking roller and the drum, and one of the guide rollers is provided with a plurality of grooves perpendicular to the roller, and the distance between the grooves is equal. The guide roller is provided with a fixed rod, and the fixed rod is fixed on the frame, and the fixed rod is provided with a plurality of tool holders, and the blade holder is provided with blades; one side of the fixed rod There is a waste material recycling rack, and a plurality of guide grooves are arranged on the waste material recycling rack; the heating box connected with the good material feeding bin is provided with two inlets on the mixer, and is connected with the secondary material feeding bin The heating box has only one inlet on the mixer, and the inlet is located in the middle of the upper two inlets.

A clamp for a spare charging roller is arranged above the unloading roller, the clamps of the spare charging roller are connected to the air cylinder and arranged at both ends of the frame, and a spare charging roller is arranged between the clamps of the spare charging roller .

The bottom of the frame is provided with a rotating shaft, the two ends of the rotating shaft are provided with small sprockets, the two ends of the unloading roller are provided with a fixed frame, and the top of the fixed frame is provided with an arc-shaped stop rod. Gear rods are arranged on both sides of the fixed frame, a cutter is arranged between the fixed frames, large sprockets are arranged at both ends of the fixed frame, and the large sprocket and the small sprocket are connected by a chain.

A waste disposal device is provided on one side of the frame.

As a preference, on the guide roller provided with grooves, the distance between grooves is 1 cm.

Preferably, the rotating shaft is connected with a motor.

As a preference, a motor is arranged vertically on the feeding port at the top of the reclaimed material feeding bin. This structure prevents the clogging of the feeding port caused by waste materials entering the feeding port due to their light weight and not easy to fall.

The processing method of the present invention: add good materials, inferior materials, and recycled materials into the respective feeding bins through feeding pipes, and melt the added materials through the heating box at the bottom of the feeding bins, and the melted materials pass through the heating box. The other end enters the mixer, because the heating box connected to the good material feeding bin has two inlets on the mixer, while the heating box connected to the secondary material feeding bin has only one inlet on the mixer, and The position of the inlet is located in the middle of the upper two inlets, so the liquid entering the mixer has three layers, and flows into the corresponding roller at the bottom through the die head. Since the roller is equipped with cooling water, the liquid is condensed and solidified to form a film shape, the film passes through the guide shaft and finally winds on the charging cylinder through the feeding roller; when the loaded material reaches the set value in the control box, the control box sends an instruction to make the cutting knife round the feeding roller in an arc shape The movement cuts off the winding film between the unloading roller and the charging roller, and at the same time, the spare charging roller descends under the action of the cylinder at one end, and winds the cut film on the spare charging roller. The charging roller for charging is drawn out along the empty groove driven by the cylinders on both sides. Since the position of the lowest end of the cylinder is lower than the position of the arc bar, the spare charging roller is just right when the cylinder descends. It falls onto the arc groove of the arc-shaped gear bar, and falls into the position of the previous charging roller along the rotation of the cutting knife for feeding; during the production process of the film, the position of the knife holder can be artificially adjusted to change the film During the cutting process, the cut film is output through the guide groove on the waste recycling rack, and finally returns to the recycling material feeding bin.

In the processing device and processing technology of a high-strength stretch stretch film obtained in the present invention, a certain amount of secondary materials are added to the original processing technology, and the waste materials generated during production are also recycled through the recycling material feeding bin. Entering into the production process, the use cost of raw materials in production is greatly reduced, and the generation of waste is reduced; one of the guide rollers is evenly provided with 1cm wide grooves to facilitate the width of the film in the production process. The measurement is convenient for workers. The loading roller can automatically unload under the action of the cylinder without manual unloading. The contact with the machine greatly reduces the incidence of accidents and provides an additional guarantee for the life safety of workers. This kind of structure and process design is more reasonable, which effectively reduces the production cost, thereby improving the competitiveness of the enterprise in this industry, and the reasonable recycling of waste materials greatly reduces the generation of waste materials. At present, enterprises adopt secondary production methods, 100 Only 1 ton of waste is generated in a ton of material, which greatly reduces the generation of waste.
