[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0021] A heat-pressing structure for a PVC film production line includes two side frames 1, with heat-pressing rollers 2 rotatably mounted between the two side frames 1. A cleaning component is also installed on the front side between the two side frames 1. In the prior art, after the PVC base film is unwound, it undergoes heat-pressing before printing the base color and drying. The prior art lacks cleaning of the PVC base film before heat-pressing. This invention installs a cleaning component on the front side of the heat-pressing structure in the existing PVC film production line. The cleaning component effectively cleans the PVC base film, significantly improving the production quality of the PVC film.

[0022] Two sets of ironing rollers 2 are vertically installed between the two machine frames 1. Each set of ironing rollers 2 includes a left ironing roller 19 and a right ironing roller 20 respectively located on the left and right sides. Tensioning rollers 14 are also rotatably installed on the upper and lower sides between the two machine frames 1. In this invention, the left ironing roller 19 and the right ironing roller 20 in one set of ironing rollers 2 can iron two sides of the PVC base film respectively.

[0023] The cleaning component includes a cleaning body 3, with a cleaning channel 4 in the middle of the cleaning body 3. When the present invention is applied, the PVC bottom film will pass through the cleaning channel 4 of the cleaning body 3. During the process of the PVC bottom film passing through the cleaning channel 4, the cleaning body 3 will clean the top and bottom surfaces of the PVC bottom film respectively, and suck away any dust that may be present on the PVC bottom film.

[0024] The cleaning body 3 has elongated air inlets 5 on its top and bottom surfaces, respectively, which connect to the cleaning channel 4. Each elongated air inlet 5 is fitted with an air inlet cap 7, which has an air inlet hole. The air inlet hole is connected to an air inlet pipe 8 via an air inlet branch pipe 16. The air inlet cap 7 seals the outer end of the elongated air inlet 5. The air inlet pipes 8 on both the upper and lower elongated air inlets 5 are connected to a blower. The blower delivers filtered air to the upper and lower air inlet pipes 8, which in turn deliver air to the upper and lower elongated air inlets 5. The upper and lower elongated air inlets 5 blow air onto the upper and lower surfaces of the PVC base film. During this blowing process, dust adhering to the surface of the PVC base film can be blown off.

[0025] The top surface of the cleaning body 3 has long air intake holes 6 on both sides of the long air intake hole 5, which are connected to the cleaning channel 4. The bottom surface of the cleaning body 3 has long air intake holes 6 on both sides of the long air intake hole 5, which are connected to the cleaning channel 4. Each long air intake hole 6 of the cleaning body 3 is equipped with an air intake end cap 9. An air intake hole is opened on the air intake end cap 9. The air intake hole is connected to the air intake pipe 10 through the air intake branch pipe (13).

[0026] The suction end cap 9 of this utility model can seal the outer end face of the suction elongated hole 6. Each suction end cap 9 has a suction hole connected to a suction pipe 10, and each suction pipe 10 is connected to an exhaust fan. During operation, the exhaust fan sucks air from the suction elongated hole 6 through the suction pipe 10. The suction elongated hole 6 sucks air from the surface of the PVC base film and removes the dust from the surface of the PVC base film.

[0027] In this utility model, by setting air intake elongated holes 6 on both sides of the air intake elongated hole 5, the air intake elongated holes 6 on both sides can suck away the air blown out of the air intake elongated hole 5, and at the same time, it can also perform two dust suction operations on the front and back of the PVC bottom film respectively.

[0028] At least one suction baffle 11 is installed at intervals along the length of the suction elongated hole 6. The top of the suction baffle 11 is fixedly connected to the suction end cap 9. In the suction elongated hole 6, there is a suction chamber 12 on both sides of the suction baffle 11. The suction end cap 9 has a suction hole on the upper side of each suction chamber 12. The suction hole is connected to the suction branch pipe 13. The suction branch pipe 13 on the suction end cap 9 is connected to a suction pipe 10.

[0029] In this invention, the suction baffle 11 divides the long suction hole 6 into at least two suction chambers 12. For example, when two suction baffles 11 are installed at intervals along the length of the long suction hole 5, the two suction baffles 11 divide the long suction hole 6 into three suction chambers 12. By setting at least two suction baffles 11, this invention allows the suction pipe 10 to draw air into each suction chamber 12 through multiple suction branch pipes 13 during suction, thus achieving more uniform air intake from the long suction hole 6.

[0030] A dividing block 17 is provided in the middle of the elongated air inlet 5, dividing the elongated air inlet 5 into two air inlet channels, each of which is inclined outward from top to bottom. This invention uses the dividing block 17 to divide the elongated air inlet 5 into two inclined air inlet channels; the left air inlet channel is inclined to the left from top to bottom, and the right air inlet channel is inclined to the right from top to bottom. By making the two air inlet channels inclined, this invention allows the airflow from the two air inlet channels to better blow away dust from the PVC base film.

[0031] The vertical cross-section of the suction elongated hole 6 is conical, and the top width of the vertical cross-section of the suction elongated hole 6 is greater than the bottom width. By designing the suction elongated hole 6 as conical, this utility model can enhance the suction force of the suction elongated hole 6 on the PVC bottom film.

[0032] The bottom of the cleaning body 3 is equipped with support legs 18.
