Description

Technical Field

[0001] The utility model relates to the technical field of PVC calendering film processing, in particular to a PVC calendering film machine. Background Art

[0002] PVC calendering film machine is a processing machine mainly used to produce various types of plastic films and PVC calendering artificial leather products. This machine is usually equipped with four or five main rollers to press the plastic material evenly.

[0003] The working principle of PVC calendering film machine is mainly based on the thermoplasticity and ductility of plastics. During the production process, the PVC raw material is first heated to a molten state, and then passes through the gap between a series of horizontally arranged and counter-rotating rollers (called calendering rollers). The rotation and pressure of these rollers cause the molten PVC material to stretch and compress in the gap between the rollers, thus forming a film with a certain thickness, width and flat surface.

[0004] The calendering roller of the existing PVC calendering film machine may be contaminated or blocked during use, such as dust, oil, etc. Impurities on the surface of the PVC film will adhere to the calendering roller. These pollutants will not only affect the surface quality of the film, but also damage the roller surface. Utility Model Content

[0005] The utility model aims at the problem that it is difficult to maintain and clean the calendering roller of a film machine. The technical problem to be solved by the utility model is to provide a PVC calendering film machine.

[0009] A further preferred solution of the present invention is that a storage box is placed on the left side of the upper end of the adjustment component.

[0010] A further preferred solution of the utility model is that a stabilizing plate is fixedly mounted on the opposite surface of the supporting leg.

[0011] A further preferred solution of the utility model is that the adjustment frame is arranged in a U shape.

[0012] A further preferred solution of the utility model is that the length of the sponge concave plate is the same as the length of the calendering roller.

[0013] A further preferred solution of the utility model is that four supporting legs are fixedly installed on the lower end of the processing table.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0022] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0023] This embodiment mainly describes a PVC calendering film machine, which is as follows:

[0024] like Figure 1-4 As shown, a PVC calendering film machine includes a processing table 1, characterized in that the upper end of the processing table 1 is movably connected with a plurality of calendering rollers 2, a slide groove 3 is provided on both the front and rear sides of the lower end of the processing table 1, an adjustment component 4 is provided at the lower end of the processing table 1, a driving component 5 is provided at the upper end of the adjustment component 4, a sponge concave plate 6 is fixedly installed on the outer surface of the driving component 5, the length of the sponge concave plate 6 is the same as the length of the calendering roller 2, the sponge concave plate 6 is located below the calendering roller 2, four supporting legs 9 are fixedly installed at the lower end of the processing table 1, and a stabilizing plate 8 is fixedly installed on the opposite surface of the supporting legs 9. The sponge concave plate 6 has good adsorption capacity due to its unique porous structure. When in contact with the roller surface of the calendering roller 2, these pores can absorb impurities, oil stains, etc. on the roller surface. As the calendering roller 2 rotates, a certain friction will be generated between the sponge concave plate 6 and the roller surface. This friction helps to remove stubborn stains or impurities on the roller surface. The sponge concave plate 6 is concave in shape. The sponge concave plate 6 has good flexibility and elasticity and can fit closely to various shapes and small undulations of the roller surface, ensuring uniformity and thoroughness of cleaning, ensuring the cleanliness of the surface of the calender roller 2, preventing impurities from adhering to the surface of the calender roller 2 and causing wear, thereby ensuring the processing quality of the film.

[0025] A storage box 7 is placed on the left side of the upper end of the adjustment component 4 , and the storage box 7 is used to collect impurities of the calendering roller 2 .

[0026] like Figure 3 As shown, the adjustment component 4 includes a first servo motor 41, a screw rod 42 is fixedly installed at the output end of the first servo motor 41, and an adjustment frame 43 is threadedly connected to the outer surface of the screw rod 42. The adjustment frame 43 is arranged in a U shape, and a limit rod 44 is movably inserted and connected to the rear side of the right end of the adjustment frame 43. The first servo motor 41 is fixedly connected to the right end of the processing table 1, and the screw rod 42 and the limit rod 44 are respectively located in the front and rear slide grooves 3. The screw rod 42 is driven to rotate by the first servo motor 41, thereby driving the adjustment frame 43 to move horizontally along the screw rod 42. The limit rod 44 is provided to limit the adjustment frame 43 to prevent the adjustment frame 43 from positional displacement. When the adjustment frame 43 moves, the sponge concave plate 6 is driven to move to the bottom of the calendering roller 2, thereby cleaning the surface of the calendering roller 2 in turn.

[0027] like Figure 4 As shown, the driving assembly 5 includes a fixed plate 51, two fixed plates 51 are provided, and the opposite surfaces of the two fixed plates 51 are commonly movably connected with a rotating shaft 52, and a second servo motor 53 is fixedly installed at the front end of the rotating shaft 52. A movable plate 54 is commonly fixedly installed at the lower ends of the two fixed plates 51, and a cylinder 55 is fixedly installed at the lower end of the movable plate 54. The cylinder 55 is fixedly connected to the lower end of the adjusting assembly 4, and the movable plate 54 is pushed upward by the cylinder 55, thereby pushing the sponge concave plate 6 to move upward and contact the surface of the calendering roller 2.

[0028] When in use, the first servo motor 41 drives the screw rod 42 to rotate, thereby driving the adjustment frame 43 to move horizontally along the screw rod 42. The limit rod 44 is set to limit the adjustment frame 43 to prevent the adjustment frame 43 from being offset. When the adjustment frame 43 moves, the sponge concave plate 6 is driven to move below the calendering roller 2, so as to clean the surface of the calendering roller 2 in turn. The cylinder 55 pushes the movable plate 54 upward, so that the sponge concave plate 6 moves upward and contacts the surface of the calendering roller 2. The sponge concave plate 6 has good adsorption capacity due to its unique porous structure. When in contact with the roller surface of the calendering roller 2, these pores can absorb impurities, oil stains, etc. on the roller surface. As the calendering roller 2 rotates, a certain friction will be generated between the sponge concave plate 6 and the roller surface. This friction helps to remove stubborn stains or impurities on the roller surface. The sponge concave plate 6 is concave in shape. The sponge concave plate 6 has good flexibility and elasticity and can fit closely to various shapes and small undulations of the roller surface, ensuring uniformity and thoroughness of cleaning, ensuring the cleanliness of the surface of the calender roller 2, preventing impurities from adhering to the surface of the calender roller 2 and causing wear, thereby ensuring the processing quality of the film.
