TECHNICAL FIELD
[0001] The present application relates to the technical field of thin film processing equipment, more specifically, it relates to an automatic film roll cutting equipment. BACKGROUND
[0002] In modern industrial production, the application of thin film materials is becoming more and more widespread, especially in the fields of packaging, electronics, medical treatment, etc. These films are usually supplied in roll form for easy storage and transportation. However, during use, the film roll needs to be cut according to specific requirements to meet different size and specification requirements.
[0003] At present, the cutting of film roll mainly relies on manual cutting. Although this traditional cutting method can barely maintain in small-scale production or simple applications, it has many defects in actual operation, which limits its application in large-scale production.
[0004] Firstly, the efficiency of manual cutting is relatively low. In the case of handling a large number of rolls, manual cutting not only takes a long time, but also is prone to errors. This deficiency in efficiency directly affects the overall progress of production, and thus affects the economic benefits of enterprises.
[0005] Secondly, manual operation is easily affected by various factors, such as operator fatigue, distraction or environmental changes, etc. These factors not only may lead to reduced cutting accuracy, but also may cause safety hazards, resulting in equipment damage or operator injury.

[0015] The application has the following beneficial technical effects:
[0016] 1. The film roll is stretched so that it passes between the support plate and the lower pressure plate. The film roll is clamped by a clamping mechanism, and the movable rod is driven by the lateral drive component to move the clamping mechanism away from the support plate, thus pulling the film. The distance the film travels from the support plate is the film cutting length. After the film is pulled to the cutting length, the lower pressure plate is driven by the lifting drive component to descend and cooperate with the support plate to clamp the film. The film is then cut by the cutting mechanism, thus separating small-width films that meet the specifications from the film roll. After the film is cut, the clamping mechanism releases the film, and the small-width films are automatically unloaded. The movable rod is driven by the lateral drive component to return the clamping mechanism to its original position and clamp the film supported by the support plate again. The lower pressure plate is then driven by the lifting drive component to rise and release the film, and the clamping mechanism pulls the film again to separate the film again. By repeating the above operation, the film roll is divided into several small-width films. This process is highly automated, requires little manual intervention, is highly efficient, and has high cutting accuracy.
[0017] 2. By setting up a rotary conveyor line to receive the cut film and stack the film on the top surface of the rotary conveyor line, the stacked films are aligned by a stacking mechanism, which reduces the need for manual stacking operations, improves the automation process of film processing, helps enterprises reduce labor costs, and improves overall processing efficiency.
[0018] 3. The stacking mechanism drives two movable seats to move closer together through a synchronous drive component. This causes the pressure blocks of the two movable seats to move towards each other and press against the opposite sides of the stacked small film segments. This makes the sides of the cut film segments neat. The stacked and neatly arranged film segments are then conveyed by a rotary drum conveyor line towards the abutment plate. The ends of the film segments are pressed against the abutment plate and neatly arranged. The stacked film segments are neatly arranged on both sides and at both ends, thus achieving stacking.

Slider blocks 12 are slidably mounted on each slide rail 11. Each slider 12 is fixedly connected to a movable rod 13 parallel to the slide rail 11. A clamping mechanism 2 is provided between the two movable rods 13. The clamping mechanism 2 includes a first clamping piece 21, with both ends of the first clamping piece 21 fixedly connected to the two movable rods 13 and arranged horizontally. A second clamping piece 22 is provided below the first clamping piece 21. The first clamping piece 21 and the second clamping piece 22 are hinged together by a hinge 23. A clamping drive assembly 24 is provided on the first clamping piece 21, and the clamping drive assembly 24 is connected to and supports the second clamping piece 22. The clamping piece 22 is inclined, and the first clamping piece 21 and the second clamping piece 22 form a figure-eight opening. The clamping drive assembly 24 is used to drive the second clamping piece 22 to engage with or open the first clamping piece 21. A support piece 3 is provided on one side of the figure-eight opening formed by the first clamping piece 21 and the second clamping piece 22. The support piece 3 is connected to the frame 1 and is parallel to the first clamping piece 21. A lower pressure piece 4 is provided above the support piece 3. The support piece 3 and the lower pressure piece 4 are parallel and symmetrical. A lifting drive assembly 31 is provided on the support piece 3. The lifting drive assembly 31 is connected to the lower pressure piece 4, supports the lower pressure piece 4, and drives the lower pressure piece 4 to rise and fall, so that the lower pressure piece 4 descends to approach the support piece 3 or rises away from the support piece 3.
[0028] Reference Figure 3 and Figure 4 The first clamping piece 21 and the second clamping piece 22 each have a plurality of clamping portions 211 arranged at intervals along their length on the side near the support piece 3. The number of clamping portions 211 on the first clamping piece 21 is equal to the number of clamping portions 211 on the second clamping piece 22 and they are arranged in a one-to-one correspondence. The support piece 3 and the lower pressing piece 4 are each provided with a plurality of clearance openings 32 arranged at intervals along their length. The clearance openings 32 of the support piece 3 and the lower pressing piece 4 are arranged in a one-to-one correspondence. The number of clearance openings 32 of the support piece 3 is equal to the number of clamping portions 211 of the first clamping piece 21 and they are arranged in a one-to-one correspondence. The clamping portions 211 of the second clamping piece 22 are allowed to pass through or out of the clearance openings 32 in the vertical direction by passing through the clearance openings 32.
[0029] Reference Figure 2 A transverse drive assembly 14 is provided on the frame 1. Both movable rods 13 are connected to the transverse drive assembly 14. The transverse drive assembly 14 drives the two movable rods 13 to reciprocate synchronously along the length of the slide rail 11.
[0030] Reference Figure 3The support plate 3 is bent downward on the side away from the first clamping plate 21 to form an mounting plate 33. A cutting assembly 5 is mounted on the mounting plate 33. The cutting assembly 5 includes a linear module 51, a connector 52, and a cutter 53. The linear module 51 is fixed on the mounting plate 33 and its length direction is parallel to the length direction of the support plate 3. The connector 52 is connected to the piston of the linear module 51. The cutter 53 is connected to the connector 52. The connector 52 acts as an extension arm so that the cutter 53 is positioned close to the side edge of the support plate 3 away from the mounting plate 33 and extends beyond the top surface of the support plate 3. The linear module 51 drives the cutter 53 to reciprocate along the length direction of the support plate 3 to cut the film.
[0031] Reference Figure 1 and Figure 2 A fixed roller 15 is rotatably mounted on the side of the support plate 3 away from the first clamping plate 21. The fixed roller 15 is located below the support plate 3. The film is wound onto the fixed roller 15. A lower roller 16 is mounted on the side of the fixed roller 15 near the support plate 3. The lower roller 16 and the fixed roller 15 are arranged side by side in the transverse direction. An upper support roller 17 is rotatably mounted between the lower roller 16 and the support plate 3. The upper support roller 17 is parallel to the lower roller 16 and the fixed roller 15 and is at the same height as the support plate 3. By stretching the film on the fixed roller 15 through the lower roller 16 and abutting against the lower surface of the lower roller 16, and then stretching it above the upper support roller 17 and abutting against the upper surface of the upper support roller 17, the stretched film is tensioned and supported by the upper support roller 17 and the lower roller 16.
[0032] By stretching the film on the upper support roller 17 to abut the top surface of the support plate 3 and the bottom surface of the clamping part 211 of the first clamping plate 21, the lifting drive assembly 31 drives the lower pressure plate 4 to descend, thereby clamping the film in conjunction with the support plate 3. The clamping drive assembly 24 drives the second clamping plate 22 to engage with the first clamping plate 21. The clamping part 211 of the second clamping plate 22 passes through the clearance opening 32 and engages with the first clamping plate 21, pressing the film against the bottom surface of the first clamping plate 21 to clamp the film. Then, the lifting drive assembly 31 drives the lower pressure plate 4 to rise and release the clamping of the film. The lateral drive assembly 14 drives the movable rod 13 to move, causing the first clamping plate 21 and the second clamping plate 22 to move away from the support plate 3, thereby pulling the film and stretching it to the required length. The lifting drive assembly 31 then drives the lower pressure plate 4 to descend and clamp the film. Finally, the linear module 51 drives the lower pressure plate 4 to descend and clamp the film. The moving cutter 53 cuts the film into small-width films that meet the specifications. After the film is cut, the clamping mechanism 2 releases the clamping of the film to automatically feed the small-width film. Then, the horizontal drive assembly 14 drives the movable rod 13 to move, so that the clamping mechanism 2 returns to its original position and clamps the film supported by the support plate 3 again. Then, the lifting drive assembly 31 drives the lower pressure plate 4 to rise and release the clamping of the film. The clamping mechanism 2 pulls the film to move again to separate the film again. By repeating the above operation, the film roll is separated into several small-width films. The automation level is high, and no manual intervention is required. The efficiency is high and the cutting accuracy is high. By setting the clamping part 211 and the clearance opening 32, the film is clamped by the first clamping plate 21 and the second clamping plate 22 in the tension state of being clamped by the support plate 3 and the lower pressure plate 4, which helps to improve the accuracy of film cutting.
[0033] Reference Figure 1 and Figure 4Furthermore, the clamping drive assembly 24 includes a mounting base 241 disposed on the top surface of the first clamping piece 21 and a first cylinder 242 fixed to the mounting base 241 and inclined thereon. A swing arm 221 is disposed on the side of the second clamping piece 22 away from the support piece 3. The swing arm 221 is V-shaped and bends towards the first cylinder 242. The telescopic shaft of the first cylinder 242 is provided with a fisheye connector, and is hinged to the swing arm 221 through the fisheye connector to support the second clamping piece 22, causing the second clamping piece 22 to be inclined and forming a V-shaped opening between it and the first clamping piece 21. The second clamping piece 22 is then driven by the extension of the first cylinder 242. The extension shaft pushes the swing arm 221 to drive the second clamping plate 22 to swing towards the first clamping plate 21 and engage with the second clamping plate 22. The retraction shaft of the first cylinder 242 retracts the swing arm 221 to pull it back to its original position, thereby driving the second clamping plate 22 to return to its original position and form a figure-eight opening with the first clamping plate 21. Multiple clamping drive components 24 are provided, and the multiple clamping drive components 24 are arranged at intervals along the length direction of the first clamping plate 21. The number of swing arms 221 is set to be multiple of the number of matching and aligning mechanisms 7. The support and drive of multiple clamping drive components 24 make the movement of the second clamping plate 22 more stable.
[0034] Reference Figure 1 and Figure 3 Furthermore, the lifting drive assembly 31 includes two second cylinders 311, which are arranged vertically and located at both ends of the lower pressure plate 4. The cylinder body of the second cylinder 311 is fixedly connected to the top surface of the lower pressure plate 4. The telescopic shaft of the second cylinder 311 passes through the lower pressure plate 4 and is fixedly connected to the top surface of the lower pressure plate 4. The lower pressure plate 4 is lifted and lowered by the extension or retraction of the telescopic rod of the second cylinder 311. When the lower pressure plate 4 rises, it moves away from the support plate 3, so that there is a gap between the lower pressure plate 4 and the support plate 3 for the film to pass through. When the lower pressure plate 4 falls, it moves closer to the support plate 3, so that the lower pressure plate 4 and the support plate 3 cooperate to clamp the film, fix the film, and facilitate better cutting of the film.
[0035] Reference Figure 1 and Figure 2Furthermore, the transverse drive assembly 14 includes first sprockets 141, chains 142, a rotating shaft 143, and a motor 144. There are four first sprockets 141 and two chains 142 (not shown in the figure). Two first sprockets 141 are located at both ends of a slide rail 11 and are rotatably connected to the frame 1, with each of these two first sprockets 141 fitted with a chain 142. The other two first sprockets 141 are located at both ends of another slide rail 11 and are rotatably connected to the frame 1, with each of these two first sprockets 141 fitted with a chain 142. The rotating shaft 143 is parallel to the fixed roller 15 and rotatably connected to the frame 1. Second sprockets 145 are provided at both ends of the rotating shaft 143, with each of the two second sprockets 145 pressing against one of the two chains 142. The lower section tensions and engages with the chain 142. The upper sections of both chains 142 are equipped with connecting plates. Both chains 142 are fixedly connected to two movable rods 13 through the connecting plates. The motor 144 is fixed on the frame 1 and connected to the rotating shaft 143 to drive the rotating shaft 143 to rotate in both directions. The rotation of the rotating shaft 143 in both directions drives the two chains 142 to synchronously rotate in both directions. The chain 142 drives the movable rod 13 to move back and forth along the length of the slide rail 11. The reciprocating movement of the movable rod 13 drives the clamping mechanism 2 to move closer to or away from the support plate 3. When the clamping mechanism 2 moves closer to the support plate 3, it clamps the film. When the clamping mechanism 2 moves away from the support plate 3, it pulls the film to achieve the required cutting length between one side of the film and the support plate 3.
[0036] Reference Figure 5 and Figure 6An automatic film roll slitting device includes a rotary conveyor line 6 and an alignment mechanism 7 disposed on the rotary conveyor line 6. The rotary conveyor line 6 is located below the moving path of the movable rod 13 and is used to receive and transport the cut film sheets. The alignment mechanism 7 is located at the bottom of the rotary conveyor line 6 and is connected to the frame of the rotary conveyor line 6. The alignment mechanism 7 includes guide shafts 71, fixed seats 72, movable seats 73, and synchronous drive components 74. There are two guide shafts 71, both of which are fixedly connected to the frame of the rotary conveyor line 6 and are arranged in parallel and symmetrically, parallel to the rotary drum of the rotary conveyor line 6. The fixed seat 72 is installed in the middle of the two guide shafts 71. There are two movable seats 73, which are located on opposite sides of the fixed seat 72 and are slidably connected to the guide shafts 71 to provide sliding support for the guide shafts 71. Each of the two movable seats 73 is provided with a pressure block 731. The pressure block 731 is connected to the rotary conveyor line 6 via two adjacent rotary shafts. The gap between the cylinders extends to the top of the rotary drum conveyor line 6. The synchronous drive assembly 74 includes a linkage hinge arm 741, a connecting rod 742, and a third cylinder 743. The linkage hinge arm 741 is located on the bottom surface of the fixed seat 72, and the middle part of the linkage hinge arm 741 is rotatably connected to the fixed seat 72. There are two connecting rods 742. One end of one connecting rod 742 is hinged to one end of the linkage hinge arm 741, and the other end of the connecting rod 742 is hinged to a movable seat 73. The other connecting rod 742... One end of the connecting rod 742 is hinged to the other end of the linkage arm 741, and the other end of the connecting rod 742 is hinged to another movable seat 73. The third cylinder 743 is fixed on the fixed seat 72, and the telescopic shaft of the third cylinder 743 is parallel to the connecting rod 742 and connected to a movable seat 73, driving the movable seat 73 to move closer to or away from the fixed seat. When the movable seat 73 moves, it drives another movable seat 73 to move synchronously in the opposite direction through the action of the connecting rod 742 and the linkage arm 741. After the film is cut into small-width films, the small-width films naturally fall onto the rotary conveyor line 6. The transverse drive assembly 14 then drives the movable rod 13 to move, so that the small-width films are pulled by the first clamping piece 21 and the second clamping piece 22 to the pressure block 731 on the two movable seats 73. The two movable seats 73 move closer to each other, so that the pressure block 731 of the two movable seats 73 moves towards each other and presses against the opposite sides of the stacked small-width films, so that the sides of the cut film segments are neat.
[0037] Reference Figure 5 and Figure 6The stacking mechanism 7 also includes a crossbar 75 on one side of the guide shaft 71, an abutment drive assembly 76, and an abutment plate 77. The abutment drive assembly 76 is a fourth cylinder, which is fixedly connected to the crossbar 75 and arranged vertically. The telescopic shaft of the fourth cylinder is connected to the abutment plate 77. The abutment plate 77 is located between two adjacent rotating drums of the rotary conveyor line 6. Driven by the fourth cylinder, the abutment plate 77 passes through the gap between two adjacent rotating drums of the rotary conveyor line 6 to the top of the rotary conveyor line 6. The rotary conveyor line 6 moves several small-width films stacked and aligned on both sides towards the abutment plate 77. The ends of the films are abutted and aligned by the abutment plate 77. The stacked films are aligned on both sides and at both ends to achieve stacking. Then, the abutment plate 77 is driven by the fourth cylinder to descend and transport the films to avoid obstacles. The rotary conveyor line 6 transports the films to the corresponding positions for unloading. The rotary conveyor line 6 is existing technology and will not be described in detail in this embodiment.
