The bushing is mounted on the mounting shaft, and a limit groove that cooperates with the limit protrusion is provided on the inner wall of the bushing. A slide fixing seat is provided on one side of the bushing.
[0004] The edge-cutting device in the aforementioned patent can only perform a simple edge-cutting function. In the film extrusion process, the cooling of the film is crucial. Its core purpose is to quickly fix the film shape, ensure the stability of physical properties, and adapt to subsequent processing procedures. If the edge is cut without calendering and cooling, it will lead to tearing and stretching of the film, and the slitting effect of the film cannot be guaranteed. Utility Model Content
[0005] The purpose of this invention is to provide a cutting machine with mold temperature cooling function for a film extrusion production line, which can perform calendering, cooling and cutting of film in one integrated process, thereby ensuring the cooling effect of the film. After cooling and shaping, cutting will not cause tearing, thus ensuring the cutting effect of the film; thereby solving the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A trimming machine with mold temperature cooling function for a film extrusion production line includes a frame body, which is laterally fixed inside by two crossbeams. A first water-cooled roller is provided at the middle position of the top of the frame body. A second water-cooled roller is provided below the first water-cooled roller. Both ends of the first and second water-cooled rollers are installed in conjunction with the frame body through bearing seats. The first water-cooled roller has a calendering roller on one side and a shaping roller on the other side; both ends of the calendering roller and the shaping roller are connected to the adjustment assembly.
[0007] As a further technical solution of this utility model, the adjustment component includes a sliding bearing with a mounting plate; the sliding bearing with a mounting plate is slidably connected to the slide rail, and the slide rail is fixed to the frame; the outer side of the sliding bearing with a mounting plate is also provided with a transmission component that is connected to the calendering roll or the shaping roll.
[0008] As a further technical solution of this utility model, one end of the sliding bearing with seat is fixed to the cylinder rod of the adjusting cylinder, and the other end of the adjusting cylinder is movably connected to the frame body through a rotating shaft.
[0009] As a further technical solution of this utility model, two side uprights are provided on one side of the frame body, and the two side uprights are also fixedly connected by a crossbeam. U-shaped connecting frames are also provided on the two side uprights. Two slitting rollers are installed on the U-shaped connecting frames. Multiple slitting blades are provided above the slitting rollers. Multiple transition rollers are also installed between the two side uprights through bearings.
[0010] As a further technical solution of this utility model, the slitting blade is installed on the hexagonal prism, and the two ends of the hexagonal prism are fixed on the U-shaped connecting frame by the mounting base; the inner side of the side stand is also provided with two winding components, and the lower end of the winding components is fixed on the sliding seat; the two sliding seats are slidably connected to the guide rod and are connected to the lead screw drive.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this invention, the extruded film enters between the first water-cooling roller and the calendering roller to calender the film and ensure the uniformity of the film thickness; then, after the film passes 3 / 4 of the way around the second water-cooling roller, it passes through a transition roller and exits between the first water-cooling roller and the shaping roller. Because the contact area between the film and the second and first water-cooling rollers is large, it has a good mold temperature control effect and can quickly achieve the purpose of cooling the film. 2. In this utility model, when the cylinder rod of the adjusting cylinder extends, it can drive the sliding bearing with seat to slide laterally along the slide rail, thereby adjusting the distance between the first water-cooling roller and the calendering roller or the shaping roller and the first water-cooling roller, thereby ensuring the calendering and shaping effect of the film. 3. In this utility model, after the film has cooled and set, it passes through the transition roller and the slitting roller. The relative width of the two middle slitting blades is adjusted according to production needs, and the position of the two outer slitting blades is adjusted, so that the film can be slitted while the irregular parts of the film edge are trimmed and cut.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-5 In this embodiment of the present invention, a trimming machine with mold temperature cooling function for a film extrusion production line includes a frame body 1. The frame body 1 is laterally fixed inside by two crossbeams 7. A first water-cooled roller 2 is provided at the middle position of the top of the frame body 1. A second water-cooled roller 6 is provided below the first water-cooled roller 2. Both ends of the first water-cooled roller 2 and the second water-cooled roller 6 are installed in conjunction with the frame body 1 through bearing seats. The first water-cooled roller 2 has a calendering roller 3 on one side and a shaping roller 4 on the other side; both ends of the calendering roller 3 and the shaping roller 4 are connected to the adjustment assembly 5.
[0020] By adopting the above technical solution, the extruded film enters between the first water-cooling roller 2 and the calendering roller 3 to calender the film and ensure the uniformity of the film thickness. Then, after the film passes 3 / 4 of the second water-cooling roller 6, it passes through a transition roller and exits between the first water-cooling roller 2 and the shaping roller 4. Since the contact area between the film and the second water-cooling roller 6 and the first water-cooling roller 2 is large, it has a good mold temperature control effect and can quickly achieve the purpose of cooling the film.
[0021] In this embodiment, the adjustment component 5 includes a sliding bearing 51; the sliding bearing 51 is slidably connected to the slide rail 52, and the slide rail 52 is fixed on the frame body 1; the outer side of the sliding bearing 51 is also provided with a transmission component 54 that is connected to the calendering roller 3 or the shaping roller 4.
[0022] More specifically, one end of the sliding bearing 51 is fixed to the cylinder rod of the adjusting cylinder 53, while the other end of the adjusting cylinder 53 is movably connected to the frame body 1 via a rotating shaft.
[0023] By adopting the above technical solution, when the cylinder rod of the adjusting cylinder 53 extends, it can drive the sliding bearing 51 to slide laterally along the slide rail 52, thereby adjusting the distance between the first water-cooled roller 2 and the calendering roller 3 or the shaping roller 4 and the first water-cooled roller 2, thus ensuring the calendering and shaping effect of the film.
[0024] The transmission assembly 54 is a transmission unit consisting of a motor and a reducer. The reducer is fixed on the outside of the sliding bearing 51, which can also ensure its transmission effect when the calendering roll 3 or the shaping roll 4 moves.
[0025] In this embodiment, two side frames 8 are also provided on one side of the frame body 1. The two side frames 8 are also fixedly connected by a crossbeam 7, and a U-shaped connecting frame 9 is provided on the two side frames 8. Two slitting rollers 10 are installed on the U-shaped connecting frame 9. Multiple slitting blades 13 are provided above the slitting rollers 10. Multiple transition rollers 11 are also installed between the two side frames 8 through bearings.
[0026] More specifically, the slitting blade 13 is mounted on the hexagonal prism 12, and the two ends of the hexagonal prism 12 are fixed to the U-shaped connecting frame 9 by mounting seats; the inner side of the side stand 8 is also provided with two winding assemblies 15, and the lower end of the winding assembly 15 is fixed on the sliding seat 14; the two sliding seats 14 are slidably connected to the guide rod 16 and are connected to the lead screw 17 for transmission.
[0027] By adopting the above technical solution, after the film is cooled and shaped, it passes through the transition roller 11 and the slitting roller 10. The relative width of the two middle slitting blades 13 is adjusted according to production needs, and the position of the two outer slitting blades 13 is adjusted, so that the film can be slitted while the irregular parts of the film edge are trimmed and cut. Workers roll up the excess material cut off from the film onto the winding assembly 15, and use the winding assembly 15 to collect the excess material. This ensures normal film transmission while preventing the excess material from interfering with normal operations.
[0028] In addition, the lead screw 17 is a bidirectional lead screw, which can realize the relative movement of the two sliding seats 14 along the guide rod 16 by manual rotation or motor drive. This can adjust the relative distance between the two winding components 15, thereby enabling the winding process of films with different widths after edge trimming.
[0029] The working principle of this utility model is as follows: the extruded film enters between the first water-cooling roller 2 and the calendering roller 3 to calender the film and ensure the uniformity of the film thickness; then the film passes through 3 / 4 of the second water-cooling roller 6, passes through a transition roller, and exits between the first water-cooling roller 2 and the shaping roller 4. Since the contact area between the film and the second water-cooling roller 6 and the first water-cooling roller 2 is large, it has a good mold temperature control effect and can quickly achieve the purpose of cooling the film. When the cylinder rod of the adjusting cylinder 53 extends, it can drive the sliding bearing 51 to slide laterally along the slide rail 52, thereby adjusting the distance between the first water-cooled roller 2 and the calendering roller 3 or the shaping roller 4 and the first water-cooled roller 2, thus ensuring the calendering and shaping effect of the film. After cooling and shaping, the film passes through the transition roller 11 and the slitting roller 10. The relative width of the two middle slitting blades 13 is adjusted according to production needs, and the position of the two outer slitting blades 13 is adjusted, so that the film can be slitted and irregular parts of the film edge can be trimmed and cut at the same time. Workers roll up the excess material cut off from the film onto the winding assembly 15, and use the winding assembly 15 to collect the excess material. This ensures normal film transmission while preventing the excess material from interfering with normal operations.
[0030] In addition, the lead screw 17 is a bidirectional lead screw, which can realize the relative movement of the two sliding seats 14 along the guide rod 16 by manual rotation or motor drive. This can adjust the relative distance between the two winding components 15, thereby enabling the winding process of films with different widths after edge trimming.

Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
