Description

Technical Field

[0001] This utility model relates to the field of PE protective film technology, and in particular to a device for recycling PE protective film production debris. Background Technology

[0002] PE protective film is the simplest high-molecular organic compound in terms of structure and is the most widely used polymer material in the world today. PE protective film uses special polyethylene plastic film as the base material and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to different densities.

[0003] Currently, the scraps generated during the production of PE protective film need to be crushed, recycled, and reused. However, there are still some shortcomings: during the recycling process, the scraps generate static electricity through friction, which is adsorbed into the crushing blade or the cavity of the recycling device, resulting in incomplete crushing and affecting the recycling efficiency. In addition, a lot of dust is generated during the crushing process, which affects the health of the operators. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a PE protective film production waste recycling device that eliminates static electricity in the PE protective film, prevents it from adsorbing into the recycling device's cavity, facilitates thorough crushing, improves recycling efficiency, and prevents dust from flying.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a PE protective film production waste recycling device, comprising:

[0006] Z-shaped conveyor section;

[0007] A connector is provided at the end of the Z-shaped conveyor section to receive protective film fragments conveyed by the Z-shaped conveyor section;

[0008] The dust collection unit is located at the top of the connector and is used to collect dust generated at the Z-shaped conveyor and the connector.

[0009] A crushing and collecting section is located at the bottom of the connector to collect and crush protective film fragments;

[0010] The static eliminator includes a first ion fan disposed on the Z-shaped conveyor section, a second ion fan disposed on the crushing and collecting section, and a static eliminator rod disposed in the middle of the crushing and collecting section. The first ion fan is used to eliminate static electricity on the Z-shaped conveyor section, the second ion fan is used to eliminate static electricity on the connecting member, and the static eliminator rod is used to eliminate static electricity generated during crushing in the crushing and collecting section.

[0011] Furthermore, the Z-shaped conveyor section includes a protective shell and a Z-shaped conveyor belt disposed inside the protective shell;

[0012] It also includes a feed inlet located on the top of the protective housing and a feeding plate located on the Z-shaped conveyor belt;

[0013] It also includes baffles symmetrically arranged along the length of the Z-shaped conveyor belt.

[0014] Furthermore, the connector has a feeding port at the end of the Z-shaped conveyor section away from the feed inlet, and the connector is used to collect the protective film fragments conveyed by the Z-shaped conveyor section.

[0015] Furthermore, the dust removal unit includes a dust collection box disposed on one side of the crushing and collecting unit and a dust adsorption plate disposed on the top of the connector;

[0016] It also includes a connecting pipe installed on top of the dust adsorption plate for conveying dust to the dust collection box, a pump body is provided in the middle of the connecting pipe, and a dustproof net is provided inside the dust collection box;

[0017] It also includes a breather valve located on top of the dust collection box and a dust removal liquid located inside the dust collection box for dust removal.

[0018] Furthermore, the connecting pipe extends to the bottom of the dustproof net, and the level of the dust removal liquid is located above the dustproof net.

[0019] Furthermore, the crushing and collecting section includes a crushing box disposed at the bottom of the connector and a funnel disposed at the bottom of the crushing box for discharging the crushed protective film;

[0020] It also includes crushing rollers symmetrically arranged inside the crushing box and partitions arranged inside the crushing box and located on the crushing rollers.

[0021] Furthermore, the crushing roller is provided with a conical blade, and the partition plate is provided with a groove adapted to the crushing roller.

[0022] The beneficial effects of this utility model are reflected in:

[0023] This invention receives protective film fragments through the feed inlet on the Z-shaped conveyor section. A feeding plate and baffles on the Z-shaped conveyor belt prevent the fragments from falling. The fragments enter the connector along the Z-shaped conveyor belt, where a first and second ion fan removes static electricity. A pump then extracts dust from the connector, which is transported via a dust suction cup and connecting pipe to a location below the dustproof plate and dust removal liquid. The purified gas is discharged through a breather valve. The fragments are then thoroughly pulverized by a powder roller and partitions. Static electricity is eliminated from the pulverized protective film using an anti-static rod, preventing the film from adhering to the Z-shaped conveyor belt outlet, connector, and the inner wall of the pulverizing chamber. This process eliminates static electricity in the PE protective film, preventing it from adsorbing into the recycling device's cavity, facilitating thorough pulverization, improving recycling efficiency, and preventing dust from flying.

[0036] Please see Figure 1-5 This utility model discloses a PE protective film production waste recycling device, comprising:

[0037] Z-shaped conveyor 1 is located below the discharge port of the protective film production equipment to convey and collect protective film fragments;

[0038] Connector 2 is provided at the end of Z-shaped conveyor 1 to receive protective film fragments conveyed by Z-shaped conveyor 1. Connector 2 is used to collect and convey protective film to prevent protective film fragments from falling at Z-shaped conveyor 1 and crushing and collecting section 4.

[0039] The dust removal unit 3 is located on the top of the connector 2 to collect the dust generated at the Z-shaped conveyor 1 and the connector 2. The dust removal unit 3 is located on one side of the crushing and collecting unit 4 to prevent dust from flying and avoid harming the health of the operators.

The first ion fan 51 is used to eliminate static electricity on the Z-shaped conveyor section 1, the second ion fan 52 is used to eliminate static electricity on the connector 2, and the static eliminator rod 53 is used to eliminate static electricity generated during crushing in the crushing and collecting section 4. The first ion fan 51 and the second ion fan 52 have the same structure and working principle. The ion fan generates positive and negative ions by ionizing air with high voltage and blows them toward charged objects to neutralize static electricity. The static eliminator rod 53 generates positive and negative ions on a metal rod through a high voltage generator to directly neutralize nearby static electricity.

[0042] During use, the debris generated by the protective film production equipment enters the crushing and collecting section 4 through the Z-shaped conveyor section 1 and the connector 2. The crushing and collecting section 4 thoroughly crushes the protective film debris. The generated dust is treated and collected by the dust removal section 3 to prevent dust from flying. Then, the first ion fan 51 eliminates static electricity on the protective film at the end of the Z-shaped conveyor section 1 to prevent the debris from adhering to the inner wall of the Z-shaped conveyor section 1 and the connector 2 when static electricity is generated. Then, the second ion fan 52 and the static elimination rod 53 eliminate static electricity on the protective film debris in the crushing and collecting section 4 to avoid the protective film debris adhering to the inner wall of the crushing and collecting section 4, which is conducive to the thorough crushing of the protective film.
