Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of film cleaning, and more specifically to a plastic film cleaning device. Background Art
[0002] China's plastic film industry is in a stage of vigorous development. Plastic film is most widely used in the field of packaging. It can be used for food packaging, electrical product packaging, daily necessities packaging, clothing packaging, etc. The dirty and old plastic film after use is non-degradable. If it is discarded casually, it will cause great harm to the environment and waste resources. Therefore, the dirty and old plastic film is recycled and can be reused after being crushed and cleaned.
[0003] In the process of recycling and cleaning plastic films, because plastic films are light in weight and tend to float on the water surface, the films need to be pressed into the water for immersion and repeated scrubbing to achieve a better cleaning effect. Traditional plastic cleaning equipment, such as vertical or horizontal cleaning equipment, cannot press the plastic film into the water well with paddles, and cannot ensure that the waste plastic can be completely immersed in the water. The film floating on the water surface cannot be soaked and scrubbed, so the cleaning effect is poor and dirt is easily left. Incomplete cleaning will affect the subsequent recycling process of the plastic film processing. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the existing film cleaning equipment with poor cleaning effect, and to provide a plastic film cleaning equipment. The utility model uses a diversion baffle to divert the movement direction of the plastic film material in the barrel body, and the water flow drives the plastic film material to move in a directional manner. The movement directions do not interfere with each other, which is conducive to pressing the material into the cleaning liquid for compression friction and full immersion, and can achieve a good cleaning effect.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A plastic film cleaning device comprises a barrel body, a feed port and a discharge port respectively arranged at the upper and lower ends of the barrel body, a stirring screw with one end inserted and extending into the barrel bottom of the barrel body and rotatable along its own axis, and a diverter baffle plate which is arranged around the outside of the stirring screw and passes through both ends, the diverter baffle plate is suspended in the barrel body and the upper and lower openings do not abut against the inner wall of the barrel body.
[0007] It should be noted that the barrel body is used to contain plastic film materials and cleaning liquid, and an inner and outer double-layer flow channel is formed between the diverter baffle and the barrel body. After the plastic film material enters the barrel body from the feed inlet, the plastic film material tends to float on the surface of the cleaning liquid due to its low density. Under the spiral feeding of the stirring screw, the floating plastic film material is drawn into the flow channel inside the diverter baffle, and moves toward the bottom of the diverter baffle with the movement of the stirring screw. In this process, the plastic film material is pressed into the water and restricted from floating by the diverter baffle and the stirring screw. In the process of the plastic film material moving downward in a directional manner and being compressed and transported, the plastic film material is fully soaked and the plastic film materials are mutually The scrubbing effect is achieved by friction and extrusion. The plastic film material is transported to the opening at the lower end of the diverter baffle by the stirring screw and then released. Driven by the water flow, the plastic film material rotates and floats from the space between the outer wall of the diverter baffle and the inner wall of the barrel body to the upper part of the cleaning liquid, and circulates for downward pressure, immersion and scrubbing. The utility model utilizes the diverter baffle to divert the movement direction of the plastic film material in the barrel body, and the water flow drives the plastic film material to move in a directional manner. The movement directions do not interfere with each other, which is conducive to pressing the material into the cleaning liquid for compression, friction and sufficient immersion, and can achieve a good cleaning effect. The equipment has a simple structure, low cost investment, small footprint, low energy consumption and convenient operation, and has a good application prospect.
[0008] It should also be noted that the water level of the cleaning fluid in the barrel is generally below the opening at the upper end of the diverter baffle, so that the plastic film material can be smoothly rolled into the interior of the diverter baffle.
[0009] Furthermore, the feed port is connected to a feeding assembly, which includes a feed pipe connected to the feed port, a feeding screw inserted in the feed pipe and coaxially arranged with the feed pipe, and a feed port opened on the side wall of the feed pipe, wherein the axis of the feed pipe is inclined downward and the end is connected to the feed port. In this way, the characteristics of the screw's directional forced conveying are fully utilized, the plastic film material is pushed into the barrel body by the feeding screw, and the stirring screw in the barrel body continuously presses the incoming plastic film into the diversion partition for diversion, thereby avoiding bridging and blockage of the plastic film material at the feed port.
[0010] Furthermore, the stirring screw includes a support seat fixed on the end of the barrel body, a rotating main shaft inserted in the support seat and rotatable relative to the support seat, and a spiral blade fixed on the rotating main shaft, and a diversion baffle is arranged around the outer side of the spiral blade.
[0011] Furthermore, the rotating main shaft is connected to the support seat via a bearing seat. In this way, the rotating main shaft can be driven by an external driving device and rotate around its own axis to realize the rotation of the spiral blades. The rotation of the spiral blades can convey materials in a directional manner to achieve the functions of diversion and conveying.
[0012] Furthermore, the end of the rotating main shaft is provided with main shaft blades radially distributed around the outer periphery of the rotating main shaft, and the main shaft blades are located outside the diverter baffle. The main shaft blades at the bottom disperse the plastic film material delivered to the bottom opening of the diverter baffle into the barrel body, so that the plastic film material floats up again with the water flow for the next compression and scrubbing. The main shaft blades can prevent the plastic film material from clogging and accumulating, so that the plastic film material can be continuously and stably circulated and cleaned to achieve continuous production.
[0013] Furthermore, the outer diameter of the spiral blade gradually decreases from the upper end to the lower end of the barrel body, and the diameter of the diverter baffle gradually decreases from the upper end to the lower end of the barrel body. The diverter baffle is arranged in an inverted cone with the spiral blade, which can gradually increase the compression force between the plastic film materials at the lower end and improve the efficiency of friction and scrubbing.
[0014] Furthermore, the outer diameter of the main shaft blade is greater than the maximum outer diameter of the spiral blade. The main shaft blade is located outside the flow dividing baffle, and has a larger outer diameter to achieve a better dispersion effect.
[0015] Furthermore, the flow dividing baffle is connected to the inner wall of the barrel body through a supporting rod so that the flow dividing baffle is suspended in the barrel body.
[0016] Furthermore, the diameter of the barrel increases gradually from the upper end to the lower end, the discharge port is opened on the outer wall of the lower end of the barrel, and the feed port is opened on the outer wall of the upper end of the barrel, and the height of the feed port is lower than the upper end opening of the diverter baffle. The barrel has a conical structure with a small top and a large bottom. The top section of the barrel is small, and the material gathers, which helps the spiral blades of the stirring screw to press the plastic film material into the cleaning liquid. The bottom section of the barrel is large, which is conducive to the full immersion of the plastic film material and the cleaning liquid. The flow rate of the cleaning liquid is slow, so that the material floats.
[0017] Furthermore, the plastic film cleaning device also includes a barrel support connected to the bottom of the barrel. The barrel support is added to facilitate the installation and fixation of the entire device and to raise the level of the discharge port, which can reduce the difficulty of discharging.
[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] (1) The utility model utilizes the inner and outer double-layer flow channels formed between the diverter baffle and the barrel body. After the plastic film material enters the barrel body from the feed port, the plastic film material tends to float on the surface of the cleaning liquid due to its low density. Under the spiral feeding of the stirring screw, the floating plastic film material is drawn into the flow channel inside the diverter baffle and moves toward the bottom of the diverter baffle as the stirring screw moves. In this process, the plastic film material is pressed into the water and restricted from floating by the diverter baffle and the stirring screw. In the process of the plastic film material moving downward in a directional manner and being compressed and transported, the plastic film material is fully soaked, and the plastic film materials rub and squeeze each other to achieve a scrubbing effect. The plastic film material is transported to the opening at the lower end of the diverter baffle by the stirring screw and then released. Driven by the water flow, the plastic film material rotates and floats from the space between the outer wall of the diverter baffle and the inner wall of the barrel body to the upper part of the cleaning liquid, and the downward pressure, soaking and scrubbing are circulated.
[0020] (2) The utility model can achieve good cleaning effect, has simple equipment structure, low cost investment, small footprint, low energy consumption and convenient operation, and has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

The main shaft blades 25 at the bottom disperse the plastic film material delivered to the bottom opening of the diverter baffle 3 into the barrel body 1, so that the plastic film material floats up again with the water flow for the next compression and scrubbing. The main shaft blades 25 can prevent the plastic film material from being blocked and accumulated, so that the plastic film material can be continuously and stably circulated and cleaned to achieve continuous production.

[0042] like Figure 2 and Figure 3 As shown, the outer diameter of the main shaft blade 25 is greater than the maximum outer diameter of the spiral blade 23. The main shaft blade 25 is located outside the flow dividing baffle 3, and has a larger outer diameter to achieve a better dispersion effect.
[0043] It should be noted that the barrel body 1 is used to contain plastic film materials and cleaning liquid, and an inner and outer double-layer flow channel is formed between the diverter baffle 3 and the barrel body 1.
