Description

Technical Field

[0001] This invention relates to the field of plastic film technology, specifically to a plastic film washing machine. Background Technology

[0002] Plastic films are widely used in agricultural covering, product packaging, and daily protection due to their advantages such as light weight, moisture resistance, and low cost. After use or during recycling, these films often have a large amount of dirt, oil, impurities, and other pollutants attached to their surfaces. They need to be effectively cleaned in order to be recycled or meet environmental protection requirements.

[0003] Currently, the cleaning of plastic film mainly relies on traditional manual cleaning or simple mechanized processing. Manual cleaning is labor-intensive, inefficient, and consumes a lot of water, with inconsistent cleaning results, making it difficult to meet the needs of large-scale processing. Existing mechanized cleaning equipment, such as those using fixed brush rollers, water jet impact, or simple drum agitation, although reducing the burden of manpower to some extent, still has obvious drawbacks: First, the cleaning method is relatively simple, mostly unidirectional scraping or rinsing, which has limited effectiveness in removing firmly attached stains or impurities in film folds, resulting in incomplete cleaning; Second, plastic film (especially soft, long strip films) is prone to tangling and knotting during dynamic cleaning, which not only seriously hinders continuous production and affects the normal operation of equipment, but may also cause the film to be torn or damaged, resulting in material loss. Therefore, a plastic film scrubbing machine is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a plastic film washing machine to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a plastic film washing machine, including a water tank, and further comprising: The scrubbing drum is fixedly connected to the inner wall of the water tank through the mounting holes on both sides. The feed cylinder is located at the top of the water tank and is connected to the inside of the water tank; A rotating mechanism, located inside the washing drum, is used to rotate the washing components located inside the washing drum to wash the plastic film. The rotating mechanism includes: Two fixing rings are fixedly connected to the inner wall of the washing drum on both sides respectively; A polygonal tube is installed inside the washing drum, and fixed sleeves are fixedly fitted at both ends of the polygonal tube, with the fixed sleeves rotating inside the fixed ring. The scrubbing assembly includes: Multiple scrubbing plates are spirally arranged on the outer wall of the polygonal cylinder to scrub the plastic film during rotation.

[0006] Preferably, the scrubbing assembly further includes: A polygonal slide tube is slidably connected to the inner wall of a polygonal cylinder, and the outer wall of the polygonal slide tube is provided with toothed grooves; Multiple rotating rods are rotatably connected to the outer wall of the polygonal cylinder, with one end extending through and into the inner wall of the toothed groove, and the other end extending outward from the outer wall and connected to the scrubbing plate for rotating the scrubbing plate. Multiple gears are fixedly sleeved on one end of the outer wall of the rotating rod, located on one side of the tooth groove, and mesh with the tooth groove.

[0007] Preferably, the rotating mechanism further includes: Two sets of support rods are set on both sides of the washing drum and connected to the fixing rings on both sides; The push rod is fixedly connected to one end of the polygonal slide cylinder and slidably connected to the axis of the right support rod; A toothed ring is fixedly fitted onto the outer wall of a fixed sleeve and is used to drive the fixed sleeve to rotate. A tension spring, fitted onto the outer wall of the push rod, is used to pull the push rod to slide to the left.

[0008] Preferably, an annular groove is formed on the left side of the inner wall of the polygonal cylinder; The left end of the polygonal slide cylinder is fixedly connected to a slide rod, which slides within the support rod on the left side. The limiting rod is fixedly sleeved on the outer wall of the slide rod and slides within the annular groove; Two wedge-shaped push blocks are fixedly fitted onto the inner wall of the annular groove and are equidistant from each other around the circumference, used to abut the limiting rod and move to the right.

[0009] Preferably, the inclined surface of the wedge-shaped pusher contacts the limiting rod, and when it rotates with the polygonal cylinder, it abuts against the limiting rod, causing the slide rod and the polygonal slide cylinder to move to the right.

[0010] Preferably, the inner wall of the scrubbing drum is provided with a discharge component for discharging the scrubbed plastic film, the discharge component comprising: The filter screen is fixedly connected to the bottom opening of the washing drum, and two discharge pipes are fixedly connected to the bottom of the washing drum and located on both sides of the filter screen. The bottom of the scrubbing drum has two outlet holes, which are connected to the discharge pipe for discharging the scrubbed plastic film.

[0011] Preferably, the export component further includes: Multiple fixed rods are connected to the inner wall of the scrubbing drum in a circular pattern at equal intervals to cooperate with the scrubbing assembly to scrub the plastic film.

[0012] Preferably, the bottoms of the two discharge pipes are fixedly fixed through the water tank and extend outwards; A wastewater pipe is fixedly installed on the outer wall of the water tank for draining wastewater from the tank.

[0013] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This plastic film scrubbing machine, through its designed scrubbing components, not only spirals and scrubs the film as it revolves around the polygonal cylinder, but also periodically drives all scrubbing plates to swing back and forth synchronously through built-in wedge-shaped push blocks and toothed grooves. This simulates the action of constantly changing angles and directions during manual scrubbing, enabling multi-angle and all-round scrubbing and turning of the film. At the same time, the periodic change of the angle of the scrubbing plates breaks through the cleaning blind spots existing in fixed scrubbing mechanisms, ensuring that both sides of the film and the folds are thoroughly cleaned, greatly improving the uniformity and thoroughness of cleaning.

[0014] 2. This plastic film scrubbing machine, with its spiral propulsion and periodic oscillation, can continuously stretch and turn the film, effectively avoiding the tangling and knotting that easily occur in long strips of plastic film during the cleaning process. The scrubbing effect is mainly achieved through the relatively gentle rubbing between the scrubbing plate and the fixed rod, rather than sharp scraping or strong pulling. Therefore, it can efficiently remove dirt while minimizing scratches or tears on the film itself, thus protecting its physical properties.

[0015] 3. The plastic film washing machine has a filter screen at the bottom of the washing drum that can effectively intercept the film and prevent it from being lost with the wastewater. At the same time, it allows the wastewater to be filtered out freely. The wastewater and clean film are separated and discharged, which facilitates the centralized treatment or recycling of wastewater. This meets the environmental protection requirements of clean production and reduces water waste. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-9 One embodiment of the present invention is: a plastic film washing machine, including a water tank 1, and further comprising: The scrubbing drum 2 is fixedly connected to the inner wall of the mounting holes opened on both sides of the inner wall of the water tank 1; The feed cylinder 3 is located at the top of the water tank 1 and is connected to the inside of the water tank 1; The rotating mechanism 4 is located inside the scrubbing drum 2 and is used to rotate the scrubbing component 8 located inside the scrubbing drum 2 to scrub the plastic film. The rotating mechanism 4 includes: Two fixing rings 41 are fixedly connected to both sides of the inner wall of the washing drum 2, respectively; A polygonal tube 42 is disposed inside the washing tube 2, and fixed sleeves 43 are fixedly sleeved at both ends of the polygonal tube 42, and the fixed sleeves 43 rotate within the inner wall of the fixed ring 41. The scrubbing component 8 includes: Multiple scrubbing plates 87 are spirally arranged on the outer wall of the polygonal cylinder 42 to scrub the plastic film during rotation.

[0020] The scrubbing component 8 also includes: A polygonal slide cylinder 84 is slidably connected to the inner wall of a polygonal cylinder 42, and a toothed groove 85 is provided on the outer wall of the polygonal slide cylinder 84. Multiple rotating rods 86 are rotatably connected to the outer wall of the polygonal cylinder 42, with one end movably penetrating through and extending to the inner wall of the toothed groove 85, and the other end extending outward from the outer wall and connected to the scrubbing plate 87 for rotating the scrubbing plate 87. Multiple gears 88 are respectively fixedly sleeved on one end of the outer wall of the rotating rod 86, located on one side of the tooth groove 85, and meshing with the tooth groove 85.

[0021] The rotating mechanism 4 also includes: Two sets of support rods 44 are set on both sides of the washing drum 2 and connected to the fixing rings 41 on both sides; Push rod 45 is fixedly connected to one end of polygonal slide cylinder 84 and slidably connected to the axis of right support rod 44; The toothed ring 47 is fixedly sleeved on the outer wall of the fixed sleeve 43 and is used to drive the fixed sleeve 43 to rotate. A tension spring 46 is sleeved on the outer wall of the push rod 45 and is used to pull the push rod 45 to slide to the left.

[0022] An annular groove 81 is provided on the left side of the inner wall of the polygonal tube 42; The left end of the polygonal slide tube 84 is fixedly connected to the slide rod 82, and slides within the support rod 44 on the left side; The limiting rod 83 is fixedly sleeved on the outer wall of the slide rod 82 and slides within the annular groove 81; Two wedge-shaped push blocks 89 are fixedly sleeved on the inner wall of the annular groove 81 and are equidistant from each other in a circle, used to abut the limiting rod 83 to move to the right.

[0023] The inclined surface of the wedge-shaped pusher 89 contacts the limiting rod 83, and when it rotates with the polygonal cylinder 42, it abuts against the limiting rod 83, causing the slide rod 82 and the polygonal slide cylinder 84 to move to the right.

[0024] The inner wall of the scrubbing drum 2 is provided with a discharge component 7 for discharging the washed plastic film. The discharge component 7 includes: The filter screen 71 is fixedly connected to the bottom opening of the washing drum 2, and two discharge pipes 5 are fixedly connected to the bottom of the washing drum 2 and located on both sides of the filter screen 71. The bottom of the scrubbing drum 2 has two outlet holes 72, which are connected to the discharge pipe 5 for discharging the scrubbed plastic film.

[0025] Export component 7 also includes: Multiple fixing rods 73 are circumferentially and equidistantly connected to the inner wall of the scrubbing drum 2, used to cooperate with the scrubbing assembly 8 to scrub the plastic film.

[0026] The bottoms of the two discharge pipes 5 are fixedly fixed through the water tank 1 and extend outwards; Wastewater pipe 6 is fixedly installed on the outer wall of water tank 1 for draining wastewater from water tank 1.

[0027] Working principle: First, the plastic film to be cleaned is continuously fed into the scrubbing drum 2 through the feed cylinder 3. Then, using external power, such as a motor (not shown in the figure), the drive rotation mechanism 4 is started to work. The power is first transmitted to the gear ring 47, which drives the fixed sleeve 43 and the polygonal cylinder 42 to start rotating inside the fixed ring 41. Multiple scrubbing plates 87 are spirally installed on the outer wall of the polygonal cylinder 42. When the polygonal cylinder 42 rotates, these scrubbing plates rotate accordingly. The spirally arranged scrubbing plates generate axial force when rotating, similar to the principle of a screw conveyor, which pushes and transports the plastic film from the feed end to the discharge end, i.e., the direction of the discharge hole 72. During the conveying process, the membrane is immersed in the water in the water tank 1. The scrubbing plate 87 moves relative to the multiple fixed rods 73 fixedly installed on the inner wall of the scrubbing drum 2, which squeezes and rubs the membrane to initially remove dirt. At the same time, the water flow also plays a cleaning role. The scrubbing plate 87 can not only revolve but also periodically oscillate, changing the contact angle and scrubbing direction with the film. Initially, the polygonal slide cylinder 84, under the tension of the tension spring 46, tends to move to the left. The toothed groove 85 on its outer wall meshes with the gear 88 fixedly sleeved on one end of the rotating rod 86. When the polygonal cylinder 42 rotates, the annular groove 81 on its inner left side rotates accordingly. The two wedge-shaped push blocks 89 fixed to the inner wall of the annular groove 81 periodically contact the limiting rod 83 fixed on the slide rod 82. The inclined surface of the wedge-shaped push blocks 89 forces the limiting rod 83, the slide rod 82, and the polygonal slide cylinder 84 connected to it to overcome the tension of the tension spring 46 and move towards the limit rod 83. When the polygonal slide cylinder 84 moves to the right, the straight toothed groove 85 on it drives multiple gears 88 that mesh with it to rotate simultaneously. At this time, the rotation of the gears 88 drives the rotating rod 86 to rotate, thereby causing the scrubbing plate 87 installed at the other end of the rotating rod 86 to deflect. When the wedge-shaped push block 89 rotates past the limit rod 83, it loses its thrust. Under the tension of the tension spring 46, the polygonal slide cylinder 84 quickly resets to the left. The toothed groove 85 moves in the opposite direction, driving the gears 88 and the scrubbing plate 87 to swing back to the initial angle. By changing the angle of the scrubbing plate 87 back and forth, the spiral direction of the scrubbing plate 87 is changed, thereby achieving continuous back-and-forth scrubbing of the plastic film.

[0028] Furthermore, as the polygonal cylinder 42 continues to rotate, the wedge-shaped pusher 89 will contact the limiting rod 83 twice for each rotation, thereby driving the scrubbing plate 87 to complete two reciprocating swing cycles. This swing breaks the fixed angle scrubbing, allowing the scrubbing plate 87 to more effectively turn over, stretch, and scrub the film from multiple angles, preventing the film from tangling and knotting, and greatly improving the cleaning uniformity and efficiency.

[0029] The dirt and wastewater generated during the washing process enter the lower part of the water tank 1 through the filter screen 71 at the bottom of the washing drum 2. The filter screen 71 prevents the plastic film from being directly washed away. The cleaned plastic film, which is transported to the end of the washing drum 2, falls into the discharge pipe 5 through the outlet hole 72 at the bottom of the washing drum 2 under the propulsion of the spiral and the flow of water, and is finally discharged from the machine, completing the washing process. The turbid wastewater collected at the bottom of the water tank 1 can be discharged through the wastewater pipe 6.

[0030] This invention provides a plastic film washing machine. There are many methods and approaches to implement this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technology.
