Description

Technical Field

[0001] This utility model relates to the technical field of film-coating cutting devices, specifically to a cutting device for a film-coating machine. Background Technology

[0002] Laminating machines can be divided into two main categories according to the laminating type: instant laminating machines and pre-coated laminating machines. They are specialized equipment for paper and film. Instant laminating machines include three parts: gluing, drying, and hot pressing. They have a wide range of applications and stable and reliable processing performance, making them widely used laminating equipment in China. Pre-coated laminating machines do not have gluing and drying parts. They are small in size, low in cost, and flexible and convenient to operate. They are suitable not only for laminating large batches of printed materials but also for laminating small batches and scattered printed materials such as automated desktop office systems.

[0003] The current Chinese utility model patent with announcement number CN211542742U discloses a laminating mechanism for a paper laminating machine. The laminating mechanism of the paper laminating machine includes a worktable, on both sides of the upper surface of the worktable, a first support plate is fixedly connected, the upper surface of the first support plate is provided with a threaded hole, the inside of the threaded hole is threadedly connected to a threaded support column, the outer surface of the threaded support column is sleeved with a second support plate, and a measuring ruler is fixedly connected to one side of the first support plate.

[0004] Regarding the aforementioned technologies, the inventors believe that the width of the products processed by the above solutions is relatively uniform. Since the width of the products processed by customers varies, different widths of films are required. However, since the production width of the film is fixed, the width and thickness of the film are often greater than the size of the product, resulting in film waste during lamination and hindering the improvement of film utilization. Utility Model Content

[0005] Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a cutting device for a laminating machine, which can effectively solve the problem that the width of the processed products is relatively uniform, resulting in film waste during lamination and hindering the improvement of film utilization.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a cutting device for a laminating machine, including a frame. Side rollers are fixed on both sides of the top of the frame, and an adjusting assembly is fixed in the middle of the top. The adjusting assembly includes a side plate fixed to the frame and a bottom roller inserted into the side plate. Side grooves and side holes are opened on the side walls of the side plates. A rotating roller is sleeved between the side holes on both sides, and a fixing rod is sleeved between the side grooves on both sides. A cutting assembly is sleeved and fixed on the outer side of the rotating roller. The end of the cutting assembly passes through the fixing rod, and a cutter is sleeved in the middle of the fixing rod. Both sides of the fixing rod are sleeved and fixed to a rotating block. One end of the rotating block is fixedly connected to a hinge support through a hydraulic rod, and one end of the hinge support is fixedly connected to the side plate through a mounting plate. The cutting assembly includes an adjusting rod and preset holes opened on the adjusting rod.

[0009] Furthermore, the cutter is positioned at the top of the bottom roller.

[0010] Furthermore, the side grooves are arranged in multiple sets at equal intervals on the side plate, and each set of side grooves is an arc-shaped structure; driven by the hydraulic rods on both sides, the fixed rod can move in the side groove, and since the fixed rod is sleeved in the adjusting rod, its tail end can deflect around the rotating roller, thereby driving the outer cutter to deflect at an angle.

[0011] Furthermore, the adjusting rod is equidistantly sleeved on the outside of the rotating roller in multiple sets, the side hole is a vertical groove structure with multiple round holes, and the two sides of the rotating roller are sleeved in the round holes; through the side plate structure, the hydraulic rods on both sides can be fixed and limited first, and fixed to the hydraulic rods by the hinge support, and due to the arc-shaped side groove on the inner side of the side plate, the fixed rod can slide in an arc shape.

[0012] Furthermore, the adjusting rod has a structure with a round hole and a support rod at the tail end, and the preset hole is opened on the support rod; the side hole structure makes it easy for the user to lock the rotating roller in the designated round hole, which can be used to adjust the tilt angle of the outer adjusting rod, thereby adjusting the contact effect between its end cutter and the film, and thus assisting it in cutting.

[0013] Furthermore, the bottom roller is at a greater height from the ground than the side rollers on both sides.

[0014] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0015] This invention, through its rotating roller and adjusting assembly structure, allows the user to sequentially pass the film through the side roller, bottom roller, and side roller, connecting it to the unwinding and take-up devices on both sides. Because the bottom roller is positioned higher, the film is stretched upwards during movement. Driven by hydraulic rods on both sides, the fixing rod can move within the side groove. Since the fixing rod is fitted inside the adjusting rod, its tail end can deflect around the rotating roller, thereby causing the outer cutter to deflect at an angle. Therefore, during use, firstly, the thickness of the film can be adjusted to maintain the contact force between the cutter and the film surface; secondly, the spacing of the adjusting rods on the rotating roller can be adjusted according to the required cutting width to meet the size requirements of the film cutting.

[0016] In this device, the side plate structure firstly fixes and limits the hydraulic rods on both sides. The hydraulic rods are fixed by the hinge support. The arc-shaped side groove on the inner side of the side plate facilitates the arc-shaped sliding of the fixed rod. The side hole structure allows the user to easily place the rotating roller into the designated circular hole. This can be used to adjust the tilt angle of the outer adjustment rod, thereby adjusting the contact effect between the end cutter and the film, and thus assisting in cutting.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: A cutting device for a laminating machine, as shown in the attached diagram. Figure 1 -Appendix Figure 4 The system includes a frame 1, with side rollers 2 fixed to both sides of the top of the frame 1 and an adjustment assembly 5 fixed to the middle of the top. The adjustment assembly 5 includes a side plate 51 fixed to the frame 1 and a bottom roller 57 inserted into the side plate 51. The side plate 51 has a side groove 511 and a side hole 52 on its side wall. A rotating roller 3 is sleeved between the two side holes 52. A fixing rod 55 is sleeved between the two side grooves 511. A cutting assembly 4 is sleeved and fixed to the outside of the rotating roller 3. The end of the cutting assembly 4 passes through the fixing rod 55. A cutter 56 is sleeved in the middle of the fixing rod 55. Both sides of the fixing rod 55 are sleeved and fixed to a rotating block 551. One end of the rotating block 551 is fixedly connected to a hinge support 53 through a hydraulic rod 54. One end of the hinge support 53 is fixedly connected to the side plate 51 through a mounting plate. The cutting assembly 4 includes an adjustment rod 41 and a preset hole on the adjustment rod 41.

[0026] The cutter 56 is located at the top of the bottom roller 57. Through the structure of the rotating roller 3 and the adjusting component 5, the user can connect the film to the take-up and unwinding devices on both sides by passing the film through the side roller 2-bottom roller 57-side roller 2 in sequence. Since the bottom roller 57 is at a higher position, the film is stretched towards the top during movement. Driven by the hydraulic rods 54 on both sides, the fixing rod 55 can move within the side groove 511. Since the fixing rod 55 is sleeved in the adjusting rod 41, its tail end can deflect around the rotating roller 3, thereby driving the outer cutter 56 to deflect at an angle. Therefore, in use, firstly, the thickness of the film can be adjusted to maintain the contact force between the cutter 56 and the film surface; secondly, the position and spacing of the adjusting rod 41 on the rotating roller 3 can be adjusted according to the required cutting width to meet the size requirements of the film cutting.

[0027] The side grooves 511 are arranged in multiple sets at equal intervals on the side plate 51, and each set of side grooves 511 is an arc-shaped structure; the adjusting rods 41 are sleeved in multiple sets at equal intervals on the outside of the rotating roller 3; the side holes 52 are vertical groove structures with multiple round holes, and the two sides of the rotating roller 3 are sleeved in the round holes; the adjusting rods 41 have a structure with a round hole and a support rod at the tail end, and the preset hole is opened on the support rod; the bottom roller 57 is higher than the side rollers 2 on both sides; through the structure of the side plate 51, the hydraulic rods 54 on both sides can be fixed and limited, and fixed to the hydraulic rods 54 by the hinge support 53. Due to the arc-shaped side grooves 511 on the inner side of the side plate 51, the fixed rod 55 can slide in an arc shape. The side hole 52 structure allows the user to easily lock the rotating roller 3 in the designated round hole, which can be used to adjust the tilt angle of the outer adjusting rod 41, thereby adjusting the contact effect between the end cutter 56 and the film, and thus assisting in cutting.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
