Description

Technical Field

[0001] The utility model relates to the technical field of PVC film processing, in particular to PVC film processing equipment with a cleaning structure. Background Art

[0002] PVC decorative film usually undergoes an impregnation treatment during the production process. The impregnation treatment is to improve the performance of the PVC film and give it specific functional properties. To this end, the patent document discloses an impregnation device for PVC decorative film processing (application number: 202320254306.4), including lifting frames that can reciprocate up and down on both sides of the inside of the impregnation box, and through grooves are provided at both ends of the outside of the two lifting frames. Threaded rods are rotatably connected inside the two lifting frames, and a hexagonal rod is fixedly connected to the middle of the threaded rod, and the threads at both ends are opposite.

DETAILED DESCRIPTION

[0044] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0045] In conjunction with the instruction manual Figure 1 To Attachment Figure 6It can be seen that the PVC film processing equipment with a cleaning structure provided by the utility model mainly includes the following parts or components: an impregnation box 10, a guide roller 11, a stirring assembly 20, a dust hood 12, a processing box 13, a spray assembly 40, and a filter plate 14.

[0046] In the utility model, the impregnation box 10 is provided with a feed port 101, a discharge port 102, and a liquid inlet 103; a guide roller 11 is arranged in the impregnation box 10, and is used to guide the PVC film to pass through the impregnation box 10; a stirring assembly 20 is arranged in the impregnation box 10 above the guide roller 11, and is used to stir the impregnation liquid; two dust hoods 12 are respectively arranged above and below the outside of the feed port 101; a processing box 13 is arranged on one side of the impregnation box 10, and the feed port 101 on the processing box 13 is connected to the two dust hoods 101 through a dust extraction pipe 131. 2; the spray assembly 40 is arranged in the processing box 13 above the feed inlet 101, and is used to spray the dust entering the processing box 13; the filter plate 14 is horizontally arranged in the processing box 13 below the feed inlet 101, and a cleaning assembly 60 is arranged thereon, and the cleaning assembly 60 cleans the impurities on the filter plate 14 into a collection box 141 on one side of the filter plate 14, and a water hole 142 is arranged at the bottom of the collection box 141, and the impregnation box 10 below the filter plate 14 is connected to the spray assembly 40 through a drain pipe 44.

[0047] During operation, the PVC film enters the impregnation box 10 from the feed port 101, and then exits the impregnation box 10 from the discharge port 102 under the guidance of the guide roller 11. By arranging the guide roller 11 inside the impregnation box 10, the PVC film can pass through the impregnation liquid smoothly and orderly, ensuring the uniformity and continuity of the impregnation, avoiding the folding, winding or deviation of the film material during the impregnation process, and improving the impregnation efficiency and product quality. The configuration of the stirring component 20 helps to maintain the uniform mixing of the impregnation liquid, prevent the precipitation of components or excessive local concentration, ensure that the impregnation liquid is always in a suitable working state, enhance the impregnation effect, and may help to extend the service life of the impregnation liquid and reduce the cost and production interruption caused by frequent replacement. Stirring helps the material transfer between the impregnation liquid and the surface of the catalyst PVC membrane, and accelerates the diffusion rate of the active components into the pores of the PVC membrane. Especially when using the equal volume impregnation method, stirring helps the components in the solution to better enter the pores of the PVC membrane.

[0048] Two upper and lower dust hoods 12 are arranged outside the feed port 101, which can effectively capture the dust generated by the PVC film during the feeding process and ensure a healthy working environment. The dust is sent to the treatment box 13 through the dust extraction pipe 131, which realizes the centralized collection and treatment of dust, meets environmental protection requirements, and also helps to improve product quality. The treatment box 13 is equipped with a spray assembly 40, which can spray and reduce dust on the incoming dust. This dust removal treatment reduces the negative impact of dust on the impregnation effect and ensures the surface quality and performance of the final product. The design of the filter plate 14 allows the impurities that have been sprayed to be intercepted to prevent them from flowing back to the impregnation box 10 and affecting the purity of the impregnation liquid.

[0049] The impregnation tank 10 below the filter plate 14 is connected to the spray assembly 40 through a drain pipe 44, so that the liquid after passing through the filter plate 14 can flow back to the spray assembly 40, forming a closed liquid circulation system. This not only maximizes the use of the impregnation liquid and reduces wastewater discharge, but also helps to maintain the stable operation of the spray system, which is in line with the concept of sustainable development.

[0050] As an embodiment, in conjunction with the attached Figure 3 It can be seen that the stirring assembly 20 includes a stirring shaft 21, which is arranged in the impregnation box 10 above the guide roller 11 and rotates under the drive of the first motor 23. The stirring shaft 21 is provided with a stirring paddle 22; the swing assembly is connected to the stirring shaft 21, and is used to drive the stirring shaft 21 to swing, and the stirring shaft 21 always rotates when swinging. The swing assembly includes a connecting rod pair 30, which is arranged in the impregnation box 10 and connected to the stirring shaft 21; the worm wheel 25 is rotatably arranged on the connecting rod pair 30 and meshes with the worm 24 sleeved on the stirring shaft 21. When the stirring shaft 21 rotates, the transmission between the worm wheel 25 and the worm 24 drives the connecting rod pair 30 to operate, and at the same time, the connecting rod pair 30 drives the stirring shaft 21 to swing.

[0051] The first motor 23 drives the stirring shaft 21 to rotate, and the stirring shaft 21 drives the stirring paddle 22 to stir the immersion liquid. At the same time, the stirring shaft 21 drives the worm 24 to rotate, and the worm 24 drives the worm wheel 25 to rotate. Under the action of the connecting rod pair 30, the stirring shaft 21 swings while rotating.

[0052] In this embodiment, in conjunction with the attached Figure 4 It can be seen that the connecting rod pair 30 includes a connecting shaft 31 whose first end is connected to the worm gear 25; a first end of the first connecting rod 32 is connected to the second end of the connecting shaft 31; a first end of the second connecting rod 33 is rotatably connected to the inner wall of the impregnation box 10, and a second end of the second connecting rod 33 is connected to the rotating shaft of the connecting shaft 31, and a bracket in the middle of the second connecting rod 33 is connected to the rotating shaft of the stirring shaft 21; a first end of the third connecting rod 34 is rotatably connected to the inner wall of the impregnation box 10, and a second end of the third connecting rod 34 is connected to the rotating shaft of the second end of the first connecting rod 32.

[0053] When the worm wheel 25 rotates, it drives the first connecting rod 32 to rotate through the connecting shaft 31. Since the second connecting rod 33 is rotatable, the worm wheel 25 can be always engaged with the worm 24. When the first connecting rod 32 rotates, it drives the third connecting rod 34 to swing. The swing of the third connecting rod 34 can cause the first connecting rod 32 to drive the worm wheel 25 to move while rotating. Because of the second connecting rod 33, the worm wheel 25 and the worm 24, the worm wheel 25 drives the worm 24 to swing, and the worm 24 drives the stirring shaft 21 to swing.

[0054] In this embodiment, in conjunction with the attached Figure 5 It can be seen that the spray assembly 40 includes a spray pipe 41, which is horizontally arranged in the processing box 13 above the feed port 101, and a spray head 42 is arranged on it.

The adjustment assembly 50 includes a first hydraulic cylinder 51, which is arranged on the processing box 13; the middle part of the fourth connecting rod 52 is rotatably arranged on the processing box 13, and the first long slot hole 521 at the lower end of the fourth connecting rod 52 is slidably connected with the first guide column 511 provided at the end of the piston rod of the first hydraulic cylinder 51; the rack 53 is slidably arranged on the processing box 13, and the second guide column 531 on one side is slidably connected with the second long slot hole 522 provided at the upper end of the fourth connecting rod 52, and the rack 53 is meshed with the gear 54 at the end of the spray pipe 41.

[0055] The piston rod of the first hydraulic cylinder 51 is extended and retracted, and through the cooperation between the first guide column 511 and the first long slot hole 521, the fourth connecting rod 52 is driven to swing, and the second long slot hole 522 at the upper end of the fourth connecting rod 52 cooperates with the second guide column 531 of the rack 53, thereby driving the rack 53 to move back and forth horizontally, and the rack 53 drives the gear 54 to rotate alternately forward and reverse, thereby driving the nozzle 41 to swing, and the nozzle 41 sprays a large atmosphere of dust through the nozzle 42.

[0056] As an embodiment, in conjunction with the attached Figure 6 It can be seen that the cleaning assembly 60 includes a first rotating shaft 61 horizontally arranged above the filter plate 14 and rotated under the drive of the second motor 62; the scraper 63 is arranged on the filter plate 14 and is threadedly connected with the reciprocating thread segment 611 on the first rotating shaft 61. The reciprocating thread segment 611 includes two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve.

[0057] The second motor 62 drives the first rotating shaft 61 to rotate, and the first rotating shaft 61 drives the scraper 63 to scrape away impurities on the filter plate 14 through the reciprocating thread segment 611 .
