Description

Technical Field

[0001] This utility model relates to the technical field of circular die-cutting equipment, and in particular to a circular die-cutting machine for adhesive film. Background Technology

[0002] Adhesive-backed films are widely used in packaging, labeling, electronics and other industries. In their production process, adhesive-backed films often need to be die-cut into specific shapes and sizes. Rotary die-cutting machines use a continuous rotating die to perform die-cutting, and are one of the most efficient die-cutting machines.

[0003] A Chinese patent with publication number CN221717186U discloses a rotary die-cutting machine for adhesive tape, including a main body with a worktable, a first feeding roller, a second feeding roller, a first cutting seat, and a second cutting seat. A dividing roller is rotatably connected to the first cutting seat, and a die-cutting roller is rotatably connected to the second cutting seat. The edge material is cut by the dividing roller to form several film sheets, which fall onto a carrier film. A first recovery roller and a second recovery roller are rotatably connected to the main body, with the first recovery roller rotating at a lower speed than the second recovery roller. By separately setting the dividing roller and the die-cutting roller, the edge material is divided from a whole into independent small film sheets, and there is a gap between adjacent film sheets. This replaces the waste material at the step distance between adjacent finished products with the gap between adjacent film sheets, saving most of the raw material at the step distance and greatly reducing costs.

[0004] In the current technology, the carrier film is installed on the second feeding roller and finally recycled by the second recovery roller. However, the carrier film can usually be reused. However, since the carrier film is tightly wrapped on the second recovery roller, it is not only difficult to remove from the second recovery roller, but also inconvenient to put on the second feeding roller. This may cause wrinkles or loosening inside the carrier film, which is not conducive to the continuity of die cutting.

[0005] Therefore, a rotary die-cutting machine for adhesive-backed films is proposed to address the above problems. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the problem of inconvenience in quickly replacing the carrier film in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model provides a circular die-cutting machine for adhesive film.

[0008] In one embodiment of this utility model, a base is included, and a feeding mechanism is provided at one top end of the base. The feeding mechanism includes a first fixed plate fixed to the top of the base. A rotating cylinder is rotatably connected to the first fixed plate via a bearing. A circular block is fixed to one end of the rotating cylinder. A reciprocating screw is rotatably connected to the circular block via a bearing. One end of the reciprocating screw extends to the outside of the rotating cylinder and is fixedly connected to a rotating block. A moving block is threaded onto the reciprocating screw. Four connecting rods are rotatably connected to the moving block via pins. Four sliding openings are provided on the circular block. A slider is slidably connected to each sliding opening. One end of each connecting rod is rotatably connected to the slider via a pin. A film-winding shaft is fixed to the side wall of the slider away from the connecting rods. A gear ring is fixed to the outer wall of the rotating cylinder. An L-shaped plate is fixed to the first fixed plate. A motor is fixed to the L-shaped plate. A gear is fixed to the output shaft of the motor. The gear meshes with the gear ring.

[0009] In one embodiment of this utility model, two first fixing frames are fixedly connected to the top of the base near the feeding mechanism; a first guide roller is installed at the bottom of the two first fixing frames; a die-cutting roller is provided above the first guide roller, and both ends of the die-cutting roller are slidably connected to the first fixing frame through sliding blocks. A first adjusting bolt is provided on the top of each sliding block, and the first adjusting bolt is threadedly connected to the first fixing frame.

[0010] In one embodiment of the present invention, two side plates are fixedly connected to the side wall of the first fixed frame near the feeding mechanism, and a feeding roller is provided on the side plate; fastening bolts are installed at both ends of the feeding roller, and a second guide roller is rotatably connected between the two side plates.

[0011] In one embodiment of this utility model, the inner sidewalls of the sliding blocks are all fixedly connected to connecting plates, and a bidirectional ball screw is rotatably connected between the two connecting plates via bearings. Two adjusting blocks are threaded onto the bidirectional ball screw, and the bottom of each adjusting block is rotatably connected to a limit wheel. A handle is fixedly connected to one end of the bidirectional ball screw.

[0012] In one embodiment of this utility model, a discharging mechanism is provided at the bottom of the end of the base away from the feeding mechanism, and the structure of the discharging mechanism is the same as that of the feeding mechanism; a collection box is provided below the discharging mechanism.

[0013] In one embodiment of the present invention, a second fixing plate is fixedly connected to the top center of the base, and a rotating roller is rotatably connected to the second fixing plate. Two limiting rods are symmetrically fixed to the outer wall of the rotating roller, and a receiving roller is sleeved on the outer side of the rotating roller. The receiving roller is slidably connected to the outer side of the limiting rods.

[0014] In one embodiment of this utility model, two second fixed frames are fixedly connected to the top of the base. The second fixed frames are located between the receiving roller and the unloading mechanism. An electrostatic roller is installed between the two second fixed frames.

[0016] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0017] The present invention discloses a rotary die-cutting machine for adhesive-backed film. By setting up a feeding mechanism and a discharging mechanism, during feeding, a rotating block drives a reciprocating screw to rotate, which in turn drives a moving block. During this movement, the moving block moves one end of a connecting rod, while the other end of the connecting rod is restricted by a sliding opening. Therefore, the connecting rod drives a slider to slide within the sliding opening, thereby simultaneously causing the film-wrapping shaft to expand outwards until the film roll is fixed on the shaft. During unloading, simply rotating the rotating block of the discharging mechanism in the opposite direction causes the film-wrapping shaft to contract inwards simultaneously, facilitating the removal and reuse of the film roll.

[0018] The present invention discloses a rotary die-cutting machine for adhesive film, which uses limiting wheels to limit the position of the adhesive film. During the adjustment process, the handle needs to be turned, which drives the bidirectional ball screw to rotate. The bidirectional ball screw drives the two adjusting blocks to move in opposite directions, and the adjusting blocks drive the two limiting wheels to move in opposite directions until the adhesive film is limited between the two limiting wheels, thus realizing the function of limiting the position of the adhesive film.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figure 1 - Figure 6 As shown, this utility model discloses a rotary die-cutting machine for adhesive film, comprising a base 1, with a feeding mechanism at one top end of the base 1; the feeding mechanism includes a first fixed plate 2 fixedly connected to the top of the base 1, a rotating cylinder 3 rotatably connected to the first fixed plate 2 via bearings, a circular block 10 fixedly connected to one end of the rotating cylinder 3, a reciprocating lead screw 13 rotatably connected to the circular block 10 via bearings, one end of the reciprocating lead screw 13 extending to the outside of the rotating cylinder 3 and fixedly connected to a rotating block 8, and a moving block 14 threadedly connected to the reciprocating lead screw 13. Four connecting rods 15 are rotatably connected to the cylinder 4 via pins; four sliding openings 11 are provided on the circular block 10, and sliders 12 are slidably connected in each sliding opening 11; one end of each connecting rod 15 is rotatably connected to the slider 12 via pins; a film-winding shaft 9 is fixedly connected to the side wall of the slider 12 away from the connecting rod 15; a gear ring 4 is fixedly connected to the outer wall of the rotating cylinder 3; an L-shaped plate 7 is fixedly connected to the first fixed plate 2, and a motor 6 is fixedly connected to the L-shaped plate 7; a gear 5 is fixedly connected to the output shaft of the motor 6, and the gear 5 meshes with the gear ring 4.

[0029] During operation, when the carrier film is applied, the carrier film roll needs to be sleeved on the winding shaft 9. Then, the free end of the carrier film passes through the top of the first guide roller 18 and between the electrostatic roller 38 and the dust removal roller, and finally is wound onto the unloading mechanism. During the sleeved process on the winding shaft 9, the rotating block 8 drives the reciprocating screw 13 to rotate, which in turn drives the moving block 14 to move. During the movement of the moving block 14, one end of the connecting rod 15 moves. The other end of the connecting rod 15 is restricted by the sliding opening 11, so the connecting rod 15 drives the slider 12 to slide within the sliding opening 11, thereby causing the winding shaft 9 to expand outward at the same time until the carrier film roll is fixed on the winding shaft 9. When loading the carrier film, the motor 6 needs to be turned on. The output shaft of the motor 6 drives the gear 5 to rotate, which in turn drives the gear ring 4 to rotate. The gear ring 4 drives the rotating drum 3, the round block 10, and the winding shaft 9 to rotate, thereby causing the carrier film roll to rotate for loading.

[0030] Furthermore, such as Figure 4 As shown, two first fixing frames 16 are fixedly connected to the top of the base 1 near the feeding mechanism; a first guide roller 18 is installed at the bottom of the two first fixing frames 16; a die-cutting roller 17 is provided above the first guide roller 18, and both ends of the die-cutting roller 17 are slidably connected to the first fixing frame 16 through sliding blocks. The top of each sliding block is provided with a first adjusting bolt 20, and the first adjusting bolt 20 is threadedly connected to the first fixing frame 16.

[0031] During operation, a first guide roller 18 is set to guide the film; a die-cutting roller 17 is set to facilitate the die-cutting of the adhesive film; and a first adjusting bolt 20 is set to facilitate the adjustment of the height of the die-cutting roller 17, thereby adjusting the tension of the adhesive film and improving the die-cutting effect.

[0032] Furthermore, such as Figure 4 As shown, the first fixed frame 16 has two side plates 21 fixedly attached to the side wall near the feeding mechanism. The side plates 21 are provided with feeding rollers 22. Both ends of the feeding rollers 22 are equipped with fastening bolts 23. A second guide roller 24 is rotatably connected between the two side plates 21.

[0033] During operation, a feeding roller 22 is provided for feeding the adhesive film. A rotating roller is provided on the outside of the feeding roller 22, and the adhesive film is sleeved on the outside of the rotating roller. Fastening bolts 23 are provided at both ends of the feeding roller 22 for fixing the feeding roller 22. A second guide roller 24 is provided for guiding the adhesive film.

[0034] Furthermore, such as Figure 4 and Figure 5As shown, each of the sliding blocks has a connecting plate 25 fixedly connected to its inner sidewall. A bidirectional ball screw 28 is rotatably connected between the two connecting plates 25 via a bearing. Two adjusting blocks 26 are threaded onto the bidirectional ball screw 28. Each adjusting block 26 has a limit wheel 27 rotatably connected to its bottom. A handle 30 is fixedly connected to one end of the bidirectional ball screw 28.

[0035] During operation, the limiting wheel 27 is used to limit the adhesive film. During adjustment, the handle 30 needs to be turned, which drives the bidirectional ball screw 28 to rotate. The bidirectional ball screw 28 drives the two adjusting blocks 26 to move in opposite directions. The adjusting blocks 26 drive the two limiting wheels 27 to move in opposite directions until the adhesive film is limited between the two limiting wheels 27, thus realizing the function of limiting the adhesive film.

[0036] Furthermore, such as Figure 1 and Figure 3 As shown, a feeding mechanism is provided at the bottom of the base 1 at the end away from the feeding mechanism, and the structure of the feeding mechanism is the same as that of the feeding mechanism; a collection box 34 is provided below the feeding mechanism.

[0037] During operation, the unloading mechanism is set up the same as the loading mechanism. When the entire film is wound up on the unloading mechanism, unloading is required. Simply rotate the rotating block 8 of the unloading mechanism in the opposite direction, so that the film shaft 9 moves inward at the same time, making it easy to remove the film roll for reuse.

[0038] Furthermore, such as Figure 1 and Figure 6 As shown, a second fixing plate 31 is fixedly connected to the top center of the base 1. A rotating roller 33 is rotatably connected to the second fixing plate 31. Two limiting rods 19 are symmetrically fixed to the outer wall of the rotating roller 33. A receiving roller 32 is sleeved on the outer side of the rotating roller 33. The receiving roller 32 is slidably connected to the outer side of the limiting rods 19.

[0039] During operation, a take-up roller 32 is used to collect the waste adhesive film. The take-up roller 32 is inserted on the outside of the rotating roller 33 by a limiting rod 19, which makes it easy to remove the take-up roller 32 and clean up the waste adhesive film.

[0040] Furthermore, such as Figure 1 As shown, two second fixing frames 35 are fixedly connected to the top of the base 1. The second fixing frames 35 are located between the receiving roller 32 and the unloading mechanism. An electrostatic roller 38 is installed between the two second fixing frames 35. A dust removal roller 36 is provided above the electrostatic roller 38. Both ends of the dust removal roller 36 are slidably connected to the second fixing frames 35 through rectangular blocks. The top of each rectangular block is provided with a second adjusting bolt 37. The second adjusting bolt 37 is threadedly connected to the second fixing frame 35.

[0041] During operation, a dust removal roller 36 is provided to remove dust from the fertilizer on the carrier film; an electrostatic roller 38 is provided to remove static electricity from the die-cut adhesive film; and a second adjusting bolt 37 is provided to adjust the height of the dust removal roller 36 so that the dust removal roller 36 and the electrostatic roller 38 pass over the surfaces of the adhesive film and the carrier film, respectively.

[0042] Furthermore, such as Figure 5 As shown, two guide rods 29 are fixedly connected between the two connecting plates 25, and the adjusting blocks 26 are slidably connected to the guide rods 29.

[0043] During operation, the adjusting block 26 slides on the guide rod 29, which limits the movement of the adjusting block 26 in the horizontal direction.

[0044] Working principle: When the carrier film is used, it needs to be sleeved on the winding shaft 9. Then, the free end of the carrier film passes through the top of the first guide roller 18 and between the electrostatic roller 38 and the dust removal roller, and finally is wound onto the unloading mechanism. During the sleeved-on process on the winding shaft 9, the rotating block 8 drives the reciprocating screw 13 to rotate, which in turn drives the moving block 14 to move. During the movement of the moving block 14, one end of the connecting rod 15 moves. The other end of the connecting rod 15 is restricted by the sliding opening 11, so the connecting rod 15 drives the slider 12 to slide within the sliding opening 11. This causes the winding shaft 9 to expand outwards simultaneously until the film roll is fixed on the winding shaft 9. When loading the film, the motor 6 needs to be turned on. The output shaft of the motor 6 drives the gear 5 to rotate, the gear 5 drives the gear ring 4 to rotate, and the gear ring 4 drives the rotating drum 3, the circular block 10 and the winding shaft 9 to rotate, thereby driving the film roll to rotate for loading. The unloading mechanism is set up the same as the loading mechanism. When the film is completely rolled up on the unloading mechanism, it needs to be unloaded. Simply rotate the rotating block 8 of the unloading mechanism in the opposite direction, so that the winding shaft 9 simultaneously retracts inwards, making it easy to remove the unloaded film roll for reuse.

[0045] A feeding roller 22 is provided for feeding the adhesive film. A rotating roller is provided on the outside of the feeding roller 22. The adhesive film is sleeved on the outside of the rotating roller. Fastening bolts 23 are provided at both ends of the feeding roller 22 for fixing the feeding roller 22. A second guide roller 24 is provided for guiding the adhesive film. A take-up roller 32 is provided for taking up the waste adhesive film. The take-up roller 32 is inserted on the outside of the rotating roller 33 by a limiting rod 19, so that the take-up roller 32 can be removed and the waste adhesive film can be cleaned up.

[0046] The limiting wheel 27 is used to limit the position of the adhesive film. During the adjustment process, the handle 30 needs to be turned, which drives the bidirectional ball screw 28 to rotate. The bidirectional ball screw 28 drives the two adjusting blocks 26 to move in opposite directions. The adjusting blocks 26 drive the two limiting wheels 27 to move in opposite directions until the adhesive film is limited between the two limiting wheels 27, thus realizing the function of limiting the position of the adhesive film.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
