Description

Technical Field

[0001] This utility model relates to the technical field of plastic packaging film erection equipment, and in particular to an active switch structure and an anti-squatting edge erection device. Background Technology

[0002] During production, plastic packaging film is wound onto a cylinder to form a columnar structure. When the wound plastic film is removed from the production equipment, the axis of the columnar plastic film is placed horizontally on the material platform. This facilitates the external packaging protection of the packaging film. After packaging the columnar plastic film, each plastic film needs to be placed upright on a material pallet for easy loading and transportation.

[0003] When switching the cylindrical plastic film from horizontal to vertical placement, it is usually done manually by pulling one end of the film upright. This manual uprighting process can cause the end of the plastic film to buckle, which can damage packaging films coated with aluminum film. Therefore, a film-standing device is used to assist in uprighting. When operating the film-standing device, the switch structure will rise or fall with the film-standing device, affecting the manual operation of the switch.

[0004] Therefore, this application proposes an active switch structure that allows the switch structure to always be kept at a height convenient for manual operation. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing an active switch structure and an anti-squatting edge membrane device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A movable switch structure includes a guide rail fixed to the surface of a mounting bracket and a switch frame that slides on the surface of the guide rail. The switch frame slides vertically on the surface of the guide rail via two sliders. The switch frame is used to mount a switch box. A limiting component for limiting the height of the switch frame is provided on the back of the switch frame.

[0008] In some embodiments, the limiting component includes a limiting rack fixed to the side of the mounting bracket and a limiting block that cooperates with the limiting rack. The teeth on the surfaces of the limiting rack and the limiting block are all helical teeth, which are used to limit the switch frame in one direction when it slides downward.

[0009] In some embodiments, two slide rods are fixed on the side of the limiting tooth block away from the limiting tooth rack. The limiting tooth block slides horizontally on the surface of the fixed plate through the two slide rods. The fixed plate is fixed in the middle of the switch frame. Springs for pushing the limiting tooth block to engage with the surface of the limiting tooth rack are respectively sleeved on the surfaces of the two slide rods.

[0010] In some embodiments, two pull ropes are fixed to the side of the limit tooth block away from the limit rack. Two guide rings are fixed to the back of the switch frame. Two pull rods are hinged to the side of the back of the switch frame near the guide rings. The two pull rods are respectively located above and below the two guide rings. The other ends of the two pull ropes respectively pass through the fixed plate and the guide rings and are fixed to one end of the pull rod away from the hinged end.

[0011] In some embodiments, there are two groups of switch boxes with the same function. One group of switch boxes is located above the other group of switch boxes.

[0012] In some embodiments, the switch frame is in a horizontal "day" shape. Both groups of switch boxes are located inside the switch frame to protect the two groups of switch boxes.

[0013] In some embodiments, the switch box is detachably installed inside the switch frame through an insertion ring and an insertion rod. The insertion ring is fixed inside the switch frame, and the insertion rod is fixed to the side of the switch box close to the insertion ring.

[0014] This embodiment also provides an anti-squat edge vertical film device, including the above-mentioned movable switch structure.

[0015] Compared with the prior art, the present utility model provides a movable switch structure and an anti-squat edge vertical film device, having the following beneficial effects.

[0016] 1. In the present utility model, the switch frame slides vertically on the surface of the guide rail through two sliders, so that when the vertical film device rises or falls, the switch frame drives the switch box to adjust the height, compensating for the height of the movement of the vertical film device, so as to keep the switch box always at a suitable operating height.

[0017] 2. In the present utility model, by setting the limit component, the height of the switch frame is limited. By setting the insertion ring and the insertion rod, it is convenient to disassemble the switch box for easy maintenance.

[0018] Other advantages, objectives and features of the present utility model will be described in part in the subsequent specification; and in part, based on the study of the following text, it will be obvious to those skilled in the art; or, it can be taught from the practice of the present utility model.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Refer to Figure 1-6 , an active switch structure, including a guide rail 2 fixed on the surface of the installation bracket 1 and a switch frame 4 sliding on the surface of the guide rail 2. Two slide blocks 3 are fixed in the middle of the switch frame 4. The switch frame 4 slides vertically on the surface of the guide rail 2 through the two slide blocks 3. The switch frame 4 is used to install the switch box 5. Two groups of switch boxes 5 with the same function are installed on the surface of the switch frame 4. One group of switch boxes 5 is located above the other group of switch boxes 5. The switch frame 4 is in a horizontal "day" shape. Both groups of switch boxes 5 are located inside the switch frame 4 for protecting the two groups of switch boxes 5. A limit component 6 for limiting the height of the switch frame 4 is provided on the back of the switch frame 4.

[0029] Understandably, the switch frame 4 slides vertically on the surface of the guide rail 2 via two sliders 3. This allows the switch frame 4 to adjust the height of the switch box 5 as the film erecting device rises or falls, compensating for the height of the film erecting device's movement and keeping the switch box 5 at a suitable operating height. Simultaneously, to prevent the guide rail 2 from being too long and affecting the rising or falling of the film erecting device, thus limiting the travel of the guide rail 2, two sets of switch boxes 5 with identical functions are installed on the surface of the switch frame 4. When the height of the film erecting device at its highest point and the switch frame 4 at its lowest point is still relatively high, the operator can operate the film erecting device by operating the set of switch boxes 5 located at the lower position. Similarly, when the film erecting device at its lowest point and the switch frame 4 at its highest point is still relatively low, the operator can operate the film erecting device by operating the set of switch boxes 5 located at the higher position, further improving operational convenience.

[0030] Specifically, the limiting component 6 includes a limiting rack 601 fixed to the side of the mounting bracket 1 and a limiting block 602 that cooperates with the limiting rack 601. The teeth on the surfaces of the limiting rack 601 and the limiting block 602 are all helical teeth, which are used to limit the switch frame 4 when it slides downward and not to limit it when it slides upward, thus improving ease of operation. Two slide rods 604 are fixed on the side of the limiting block 602 away from the limiting rack 601. The limiting block 602 slides horizontally on the surface of the fixing plate 603 through the two slide rods 604. The fixing plate 603 is fixed in the middle of the switch frame 4. Springs 605 are respectively sleeved on the surfaces of the two slide rods 604 to push the limiting block 602 to engage with the surface of the limiting rack 601.

[0031] Two pull ropes 606 are fixed on the side of the limiting tooth block 602 away from the limiting tooth rack 601. Two guide rings 607 are fixed on the back of the switch frame 4. The height of the two guide rings 607 is equal to the height of the fixing plate 603. Two pull rods 608 are hinged on the back of the switch frame 4 near the guide rings 607. The two pull rods 608 are located above and below the two guide rings 607 respectively. The other ends of the two pull ropes 606 pass through the fixing plate 603 and the guide rings 607 respectively and are fixed to the end of the pull rod 608 away from the hinge end. The hinge end of the pull rod 608 limits the rotation angle of the pull rod 608 through the support block.

[0032] Understandably, the spring 605 pushes the limiting tooth block 602 to engage with the surface of the limiting rack 601, thereby preventing the switch frame 4 from sliding downwards under gravity and thus limiting the switch frame 4. When the switch frame 4 needs to slide, by gripping the pull rod 608, the pull rod 608 is rotated in the direction of the switch frame 4. The pull rod 608 drives the pull rope 606 to tighten, thereby causing the pull rope 606 to drive the limiting tooth block 602 to disengage from the limiting rack 601, releasing the limitation on the switch frame 4 and allowing the switch frame 4 to slide downwards. When the switch frame 4 slides upwards, only pushing the switch frame 4 upwards is needed to adjust its height, improving the convenience of operation. By setting two sets of pull ropes 606, pulling either set of pull ropes 606 can release the limitation on the switch frame 4. When the switch frame 4 is at different heights, the operator can release the limitation on the switch frame 4 using the pull rod 608 and pull rope 606 that are most convenient to operate.

[0033] Specifically, the switch box 5 is detachably installed inside the switch frame 4 via the plug ring 7 and the plug rod 8. There are two sets of plug ring 7 and plug rod 8. The two plug rings 7 are fixed inside the switch frame 4, and the two plug rods 8 are fixed on the side of the switch box 5 near the plug ring 7. The surface of the plug ring 7 is threaded with bolts for fixing the plug rod 8.

[0034] It is understandable that by setting the insertion ring 7 and the insertion rod 8, the switch box 5 can be easily disassembled and repaired; the switch box 5 can be quickly inserted into the surface of the insertion ring 7 via the insertion rod 8 and fixed with bolts, thereby quickly installing and fixing the switch box 5.

[0035] This embodiment also provides an anti-squatting edge membrane device, including the above-mentioned movable switch structure;

[0036] A first swing arm 10 is hinged to the upper end of the column 9, and a connecting seat 11 is hinged to the other end of the first swing arm 10. The first swing arm 10 swings through a first electric telescopic rod. A second swing arm 12 is rotatably connected to the surface of the connecting seat 11. A rotating beam 13 is rotatably connected to the other end of the second swing arm 12. The rotating beam 13 is vertically set, and a flipping frame 14 is hinged to the lower end of the rotating beam 13. The flipping frame 14 is driven to rotate through two second electric telescopic rods. The mounting bracket 1 is fixedly connected to the surface of the rotating beam 13.

[0037] It is understandable that the first electric telescopic rod drives the first swing arm 10 to swing, thereby driving the second swing arm 12 and the rotating beam 13 to rise and fall. By setting the connecting seat 11 and the rotating beam 13, the position of the flipping frame 14 can be adjusted. By inserting the flipping frame 14 into the center hole of the plastic film, the plastic film can be flipped to stand upright, which can effectively avoid the problem of the plastic film squatting at the edge.

[0038] In this utility model, when the first electric telescopic rod drives the first swing arm 10 to swing upward and adjust the height of the rotating beam 13 and the flipping frame 14, the pull rod 608 is gripped, causing the pull rod 608 to rotate in the direction of the switch frame 4. The pull rod 608 drives the pull rope 606 to tighten, thereby causing the pull rope 606 to drive the limiting tooth block 602 to disengage from the limiting tooth rack 601, releasing the limitation on the switch frame 4. At the same time, the operator grips the switch frame 4, causing the rotating beam 13 to drive the mounting bracket 1 and the guide rail 2 to slide upward on the surface of the slider 3, while the switch frame 4 maintains a constant height for easy operation. When the rotating beam 13 and the flipping frame 14 move downward, the operator only needs to grip the switch frame 4 to maintain its constant height, and the rotating beam 13 can drive the mounting bracket 1 and the guide rail 2 to slide downward on the surface of the slider 3.
