Technical Field

[0001] The utility model relates to the technical field of PVC calendering films, in particular to production equipment for yellowing-resistant PVC calendering films. Background Art

[0002] PVC calendered film is a closed-cell foam plastic made from polyvinyl chloride resin with auxiliary materials such as foaming agents and stabilizers added through kneading, ball milling, molding, and foaming. In addition to the product's soft and hard properties, it comes in three types: soft, brittle, and medium.

[0003] In the production process of yellowing-resistant PVC calendered film, traditional processes generally ignore the necessary cleaning and drying of the surface when preparing PVC calendered film. This omission directly leads to impurities and residual moisture attached to the surface of the PVC calendered film becoming key factors affecting the quality of the film in the subsequent film-sticking operation. Specifically, the presence of these impurities and moisture will significantly reduce the adhesion of the film, thereby causing the film to be loose or even fall off, which has an adverse impact on the overall performance and appearance quality of the product.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Embodiment 1:

[0022] Please refer to Figures 1-3 A kind of production equipment of yellowing-resistant PVC calendering film, including workbench 1, the upper surface left side of workbench 1 is provided with the first winding roller 2, the upper surface right side of workbench 1 is provided with the second winding roller 3, the upper surface of workbench 1 is fixedly installed with the first mounting frame 4, the upper surface of first mounting frame 4 is fixedly installed with air heater 5, the upper surface of first mounting frame 4 is fixedly installed with gas collection frame 6, the upper surface of gas collection frame 6 is fixedly installed with gas pressure pump 7, the front surface of air heater 5 is fixedly installed with gas pipe 8, the outer surface of gas pipe 8 is provided with check valve 9, the lower surface of first mounting frame 4 is fixedly installed with gas outlet frame 10, the upper surface of workbench 1 is fixedly installed with the third winding roller 11.

[0023] Specifically: in the process of producing PVC calendered film, first, the outer surface of the first winding roller 2 is provided with a PVC calendered film, and the outer surface of the third winding roller 11 is provided with a yellowing-resistant film. When the PVC calendered film on the surface of the first winding roller 2 moves forward, it first reaches the bottom of the first mounting frame 4. At this time, the air heater 5 and the gas pressure pump 7 are started at the same time. After the air heater 5 draws the external gas into the interior, the gas is heated. After the heated gas is transported to the interior of the gas collecting frame 6 through the conveying pipe, the gas collecting frame 6 pressurizes the heated gas and sprays it out through the air outlet frame 10, thereby blowing away the impurities adhered to the surface of the PVC calendered film and drying the surface with hot air. After the drying is completed, the PVC calendered film and the yellowing-resistant film are polymerized, and then pass through the heating roller 13. The heated and bonded yellowing-resistant PVC calendered film continues to move forward, thereby reaching the conveying roller 17. After cooling, the yellowing-resistant PVC calendered film is wound on its surface by the third winding roller 11, and the winding is completed.

[0024] In this embodiment, a third mounting frame 16 is fixedly mounted on the upper surface of the workbench 1 , a conveying roller 17 is provided on the inner wall of the third mounting frame 16 , and a cooling roller 18 is fixedly mounted on the inner wall of the third mounting frame 16 .

[0025] Specifically: At this time, the cold guide roller 18 is started to cool the coolant inside the conveyor roller 17. The cooled coolant transmits cold air to the surface of the conveyor roller 17. When the yellowing-resistant PVC calendered film passes through the conveyor roller 17, the cold air and the surface adhere to each other, thereby generating heat exchange, thereby rapidly cooling it. This design can achieve the effect of rapid cooling of the PVC calendered film after production, so that it can be directly wound up, saving time and improving work efficiency.

[0026] In this embodiment, a controller 19 is fixedly mounted on the lower surface of the workbench 1 .

[0027] In this embodiment, the interior of the gas collecting frame 6 and the interior of the gas outlet frame 10 are interconnected.

[0028] Specifically, the gas inside the gas collecting frame 6 is pressurized and then ejected through the gas outlet frame 10 .

[0029] In this embodiment, the interior of the conveying roller 17 is a hollow structure, and a cooling liquid is provided in the hollow structure. The outer surface of the cooling roller 18 is inserted and connected into the interior of the conveying roller 17 .

[0030] Specifically: the cooling liquid is cooled by a cooling roller, so that heat exchange is achieved through cold air and hot air, thereby performing a cooling process on it.

[0031] In this embodiment, the second winding roller 3 , the air heater 5 , the gas pressure pump 7 , the heating wire 15 , and the cooling roller 18 are all electrically connected to the controller 19 .

[0032] Working principle: The utility model draws in external air through the air heater 5 and heats it. After the heated gas is input into the interior of the gas collecting frame 6, the gas pressure pump 7 pressurizes it and sprays it out, so that it generates a certain force, thereby better cleaning the surface of the PVC calendered film and drying it at the same time. Compared with the related art, the production equipment of the yellowing-resistant PVC calendered film provided by the utility model has the following beneficial effects: the design can achieve the effect of cleaning and drying the PVC calendered film, thereby avoiding the presence of these impurities and moisture which will significantly reduce the adhesion of the film, and then cause the adverse consequences of loose film or even film falling off, which has an adverse effect on the overall performance and appearance quality of the product.

[0033] Example 2:

[0034] Please refer to Figures 1-3 A second mounting frame 12 is fixedly mounted on the upper surface of the workbench 1 , a heating roller 13 is movably mounted on the inner wall of the second mounting frame 12 , a heat conducting layer 14 is provided on the outer surface of the heating roller 13 , and a heating wire 15 is provided inside the heat conducting layer 14 .

[0035] Specifically: when it passes through the heating roller 13, the controller 19 controls the heating wire 15 to start, thereby heating. The heat after heating is conducted through the heat-conducting layer 14, so that the heat is evenly dispersed on the outer surface of the heat-conducting layer 14. At this time, the PVC calendering film and the yellowing-resistant film pass through at the same time, thereby heating and bonding them.

[0036] Working principle: The utility model achieves the effect of heating the entire outer surface of the heating roller 13 through evenly distributed heating appliances and a heat-conducting layer 14, so that the outer surface temperature is uniform. Compared with related technologies, the production equipment for yellowing-resistant PVC calendered film provided by the utility model has the following beneficial effects: the utility model can achieve the effect of uniform heating, thereby reducing heat transfer loss and improving heating efficiency and temperature uniformity.

[0037] The controller 19 is an existing structure, and the control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection are not described in detail.
