Abstract
Description
Technical Field
[0001] This utility model relates to a film fixing bracket for a heat sealing machine, belonging to the technical field of packaging equipment. Background Technology
[0002] In the packaging industry, heat sealing technology is a widely used and crucial process. It melts and bonds the edges of film materials together by heating, thereby forming a sealed package that effectively protects products from the effects of the external environment.
[0003] Traditional heat sealing machines use high temperature and high pressure to bond heat-sealing plastic films together. The operating temperature of heat sealing machines is generally higher than 100℃. When heat sealing the film, the operator usually holds the film and inserts it into the heat sealing area. Because the upper limbs are too close to the heat sealing machine, they are easily burned by the high temperature, making traditional heat sealing machines less safe. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a film fixing bracket for a heat sealing machine. It solves the problem that in the existing technology, traditional heat sealing machines use high temperature and high pressure to bond heat-sealable plastic films together. Generally, the operating temperature of heat sealing machines is higher than 100°C. When heat sealing the film, the operator usually holds the film and inserts it into the heat sealing area. Because the upper limbs are too close to the heat sealing machine, they are easily burned by the high temperature, which makes the traditional heat sealing machine less safe.
[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: A film fixing bracket for a heat sealing machine includes a mounting platform. A vertical frame is fixedly mounted on the upper surface of the mounting platform. A mounting cover is provided on the vertical frame. A cylinder is fixedly mounted on the mounting cover. The telescopic end of the cylinder passes through the mounting cover and is fixedly mounted with a connecting block. A mounting block is provided on the lower side of the connecting block. A fixing arm is fixedly connected to the lower surface of the mounting block. A rotating arm is rotatably connected to the side of the fixing arm away from the mounting block. A placement plate is provided on the mounting platform. A connecting groove is opened through the placement plate. A positioning block is fixedly connected to the placement plate. A support arm is fixedly connected to the positioning block. A connecting arm is slidably connected inside the support arm. The end of the connecting arm away from the positioning block is rotatably connected to the rotating arm. A heat sealing mechanism capable of heat sealing the film is mounted on the mounting block and the mounting platform. A limiting mechanism capable of limiting the placement plate is provided on the placement plate. A fixing component capable of fixing the film is provided on the placement plate. The fixing component includes multiple electric push rods fixedly mounted on the placement plate. A positioning plate is fixedly connected to the telescopic end of the electric push rod. A rubber block is fixedly connected to the side of the positioning plate near the placement plate.
[0006] By adopting the above technical solution, when in use, the film to be sealed can be placed on the placement plate, and the film to be heat-sealed can be passed through the underside of the rubber block, so that the sealing end of the film extends to the upper side of the connecting groove. At this time, the electric push rod is activated, which can drive the positioning plate and the rubber block to move downward, thereby clamping the film between the placement plate and the rubber block, thus fixing the film and preventing the film from shifting during heat sealing, thereby improving the accuracy and quality of heat sealing.
[0007] The present invention is further configured such that: the limiting mechanism includes a stabilizing frame fixedly installed on the mounting platform, the placement plate is slidably connected in the stabilizing frame, the stabilizing frame has multiple slide rail grooves, and the placement plate is fixedly connected with multiple slide rail blocks that are inserted into the slide rail grooves.
[0008] By adopting the above technical solution, the stabilizer provides a limiting effect on the placement plate, allowing the placement plate to slide only back and forth and preventing it from moving up and down or left and right, thereby ensuring the stability of the film to be packaged on the placement plate.
[0009] This utility model is further configured as follows: the heat sealing mechanism includes a second positioning seat fixedly mounted on the mounting platform, a second heat sealing block fixedly mounted on the side of the second positioning seat near the mounting block, a first positioning seat fixedly connected to the side of the mounting block near the mounting platform, and a first heat sealing block fixedly mounted on the side of the first positioning seat near the second heat sealing block. Multiple vertical rods are fixedly connected to the connecting block, slidingly extending through the outer side of the mounting cover. Multiple connecting rods are fixedly connected to the mounting block, slidingly extending through the connecting block. Multiple stabilizing springs are fixedly connected between the connecting block and the mounting block. A connecting spring is fixedly connected to the side of the connecting arm away from the rotating arm, and the end of the connecting spring away from the connecting arm is fixedly connected to the inner wall of the support arm.
[0010] By adopting the above technical solution, the stabilizing spring connects the connecting block and the mounting block, and also supports the mounting block. The starting cylinder can drive the connecting block to move downwards. The downward movement of the connecting block synchronously drives the mounting block, connecting rod, vertical rod, and stabilizing spring downwards. The downward movement of the mounting block synchronously drives the first positioning seat, first heat sealing block, and fixed arm downwards. During the downward movement of the first heat sealing block, it moves closer to the second heat sealing block. During the downward movement of the fixed arm, it pushes the rotating arm to rotate. The rotating arm synchronously applies a tensile force to the connecting arm, support arm, connecting spring, positioning block, and placement plate towards the vertical frame. In this design, the connecting spring has high elasticity and acts as a connector between the support arm and the connecting arm. Initially, the friction between the placement plate and the stabilizer is insufficient to cause elastic deformation of the connecting spring. Therefore, when the rotating arm applies tension to the connecting arm, support arm, positioning block, connecting spring, and placement plate, the connecting spring does not deform elastically, causing the connecting arm, positioning block, support arm, and placement plate to move closer to the second heat-sealing block. During this process, the slide rail block also slides within the slide rail groove. When the placement plate moves to the point where the connecting groove aligns with the second heat-sealing block, the slide rail block... The rail block abuts against the inner wall of the slide rail groove near the vertical frame. At this point, the cooperation between the rail block and the slide rail groove restricts the placement plate, preventing it from moving further towards the second heat-sealing block with the connecting arm. This ensures the connecting groove remains aligned with the second heat-sealing block. As the mounting block continues to move downwards, the connecting spring is stretched and deformed. The mounting block then drives the first heat-sealing block through the connecting groove to abut against the second heat-sealing block, pressing the film between them and thus heat-sealing the portion of the film extending into the connecting groove. This eliminates the need for manual handling of the film during heat sealing, avoiding burns to the arm from the first and second heat-sealing blocks, enhancing safety and improving the safety and practicality of the heat-sealing machine's film fixing bracket. After heat sealing is completed, the starting cylinder drives the mounting block to move upward, thereby moving the first positioning seat, the first heat sealing block, and the fixing arm upward. The upward movement of the first heat sealing block releases its contact with the second heat sealing block, thus ending the heat sealing work on the film. During the upward movement of the fixing arm, the connecting spring is first reset, and then the placement plate is pushed to reset, thereby moving the heat-sealed film away from the second heat sealing block. This keeps the heat-sealed film away from both the second and first heat sealing blocks, preventing burns to the worker's arms from the temperature of the second and first heat sealing blocks, and also making it easier to remove the heat-sealed film, thus increasing the practicality of the film fixing bracket of the heat sealing machine.As the cylinder drives the connecting block downwards, it simultaneously moves the vertical rod, connecting rod, first positioning seat, first heat-sealing block, and mounting block downwards. When the first heat-sealing block moves downwards to contact the second heat-sealing block, the cylinder drives the connecting block to continue moving downwards by one to five centimeters. During this continuous downward movement, the mounting block pushes the stabilizing spring, causing the stabilizing spring to deform under pressure between the connecting block and the mounting block. At the same time, the release force of the stabilizing spring pushes the mounting block, causing the first heat-sealing block to exert pressure on the second heat-sealing block. This applies pressure to the film sandwiched between the first and second heat-sealing blocks, heat-sealing it and preventing the film from being subjected to excessive pressure, thus ensuring the quality of the film heat-sealing.
[0011] The beneficial effects of this utility model are as follows: The starting cylinder can drive the connecting block to move downwards. Simultaneously, the downward movement of the connecting block drives the mounting block, connecting rod, vertical rod, and stabilizing spring to move downwards. Simultaneously, the downward movement of the mounting block drives the first positioning seat, first heat-sealing block, and fixed arm to move downwards. During the downward movement of the first heat-sealing block, it moves closer to the second heat-sealing block. During the downward movement of the fixed arm, it pushes the rotating arm to rotate. Simultaneously, the rotating arm applies a tensile force to the connecting arm, support arm, connecting spring, positioning block, and placement plate towards the vertical frame. In this design, the connecting spring has a large elasticity and connects the support arm and connecting arm. Initially, the friction between the placement plate and the stabilizing frame does not cause the connecting spring to undergo elastic deformation. Therefore, when the rotating arm applies a tensile force to the connecting arm, support arm, positioning block, connecting spring, and placement plate, the connecting spring does not undergo elastic deformation, causing the connecting arm, positioning block, support arm, and placement plate to move towards the second heat-sealing block. During this process, the slide block also slides within the slide rail groove. When the placement plate moves to the point where the connecting groove aligns with the second heat-sealing block, the slide... The rail block abuts against the inner wall of the slide rail groove near the vertical frame. At this point, the cooperation between the rail block and the slide rail groove restricts the placement plate, preventing it from moving further towards the second heat-sealing block with the connecting arm. This ensures the connecting groove remains aligned with the second heat-sealing block. As the mounting block continues to move downwards, the connecting spring is stretched and deformed. The mounting block then drives the first heat-sealing block through the connecting groove to abut against the second heat-sealing block, pressing the film between them and thus heat-sealing the portion of the film extending into the connecting groove. This eliminates the need for manual handling of the film during heat sealing, avoiding burns to the arm from the first and second heat-sealing blocks, enhancing safety and improving the safety and practicality of the heat-sealing machine's film fixing bracket.

[0020] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following details... Figures 1 to 6 As shown, this utility model is further illustrated.
[0021] like Figures 1 to 4As shown, this utility model is a film fixing bracket for a heat sealing machine, including a mounting platform 1. A vertical frame 2 is fixedly mounted on the upper surface of the mounting platform 1. A mounting bracket 3 is detachably fixedly mounted on the vertical frame 2 by bolts. A mounting cover 4 is fixedly mounted on the mounting bracket 3. A cylinder 5 is fixedly mounted on the mounting cover 4. The telescopic end of the cylinder 5 passes through the mounting cover 4 and is fixedly mounted with a connecting block 11. A mounting block 6 is provided on the lower side of the connecting block 11. The mounting block 6 is located on the outer side of the mounting cover 4. A fixing arm 15 is fixedly connected to the lower surface of the mounting block 6. A rotating arm 16 is rotatably connected to the side of the fixing arm 15 away from the mounting block 6. A placement plate 21 is provided on the mounting platform 1. A connecting groove 22 is provided through the placement plate 21. A positioning block 19 is fixedly connected to the placement plate 21. A support arm 18 is fixedly connected to the positioning block 19. A connecting arm 17 is slidably connected inside the support arm 18. One end of the connecting arm 17 away from the positioning block 19 extends through the outside of the support arm 18. The other end of the connecting arm 17 away from the positioning block 19 is rotatably connected to the rotating arm 16. The rotating arm 16 is inclined. A heat sealing mechanism capable of heat sealing the film is installed on the mounting block 6 and the mounting table 1. A limiting mechanism capable of limiting the placement plate 21 is provided on the placement plate 21. A fixing component capable of fixing the film is provided on the placement plate 21.
[0022] like Figures 5 to 6 As shown, the fixing assembly includes multiple electric actuators 27 fixedly mounted on the placement plate 21. The telescopic ends of the electric actuators 27 pass through the placement plate 21 and are fixedly connected to a positioning plate 26. A rubber block 28 is fixedly connected to the side of the positioning plate 26 near the placement plate 21.
[0023] In use, the film to be sealed can be placed on the placement plate 21, and the film to be heat-sealed can be passed through the lower side of the rubber block 28 so that the sealing end of the film extends to the upper side of the connecting groove 22. At this time, the electric push rod 27 is activated, which can drive the positioning plate 26 and the rubber block 28 to move downward, thereby clamping the film between the placement plate 21 and the rubber block 28, thus fixing the film and preventing the film from shifting during heat sealing, thereby improving the accuracy and quality of heat sealing.
[0024] like Figures 4 to 6 As shown, the limiting mechanism includes a stabilizer 20 fixedly installed on the mounting platform 1. The stabilizer 20 is C-shaped. The placement plate 21 is slidably connected inside the stabilizer 20. Multiple slide rail grooves 25 are provided inside the stabilizer 20. Multiple slide rail blocks 24 are fixedly connected to the placement plate 21 and inserted into the slide rail grooves 25. The slide rail blocks 24 are slidably connected to the slide rail grooves 25.
[0025] In this solution, the stabilizer 20 has a limiting effect on the placement plate 21. The stabilizer 20 ensures that the placement plate 21 can only slide back and forth and will not move up and down or left and right, thereby ensuring the stability of the film to be packaged placed on the placement plate 21.
[0026] like Figures 3 to 4 As shown, the heat sealing mechanism includes a second positioning seat 9 fixedly installed on the mounting platform 1. A second heat sealing block 10 is fixedly installed on the side of the second positioning seat 9 near the mounting block 6. A first positioning seat 7 is fixedly connected to the side of the mounting block 6 near the mounting platform 1. A first heat sealing block 8 is fixedly installed on the side of the first positioning seat 7 near the second heat sealing block 10. The first heat sealing block 8 is aligned with the second heat sealing block 10.
[0027] like Figure 4 As shown, multiple vertical rods 12 are fixedly connected to the connecting block 11. The vertical rods 12 slide through the outer side of the mounting cover 4. The movement path of the vertical rods 12 is consistent with the movement path of the telescopic end of the cylinder 5. Multiple connecting rods 13 are fixedly connected to the mounting block 6 and slide through the connecting block 11. Multiple stabilizing springs 14 are fixedly connected between the connecting block 11 and the mounting block 6. The stabilizing springs 14 are sleeved on the outer side of the connecting rods 13. The lower side of the mounting cover 4 is open to the outside.
[0028] like Figures 4 to 5 As shown, a connecting spring 23 is fixedly connected to the side of the connecting arm 17 away from the rotating arm 16. The end of the connecting spring 23 away from the connecting arm 17 is fixedly connected to the inner wall of the support arm 18. The extension and retraction direction of the connecting spring 23 is consistent with the sliding path of the connecting arm 17.
[0029] In this scheme, the first heat-sealing block 8 and the second heat-sealing block 10 have the same size, and the length and width of the connecting groove 22 are both greater than the length and width of the second heat-sealing block 10.
[0030] In this design, the stabilizing spring 14 connects the connecting block 11 and the mounting block 6, and also supports the mounting block 6. The starting cylinder 5 moves the connecting block 11 downwards. Simultaneously, the downward movement of the connecting block 11 moves the mounting block 6, connecting rod 13, vertical rod 12, and stabilizing spring 14 downwards. Simultaneously, the downward movement of the mounting block 6 moves the first positioning seat 7, first heat-sealing block 8, and fixing arm 15 downwards. During the downward movement of the first heat-sealing block 8, it moves closer to the second heat-sealing block 10. During the downward movement of the fixing arm 15, it pushes the rotating arm 16 to rotate. Simultaneously, the rotating arm 16 applies a tensile force to the connecting arm 17, support arm 18, connecting spring 23, positioning block 19, and placement plate 21 towards the vertical frame 2.
[0031] In this design, the connecting spring 23 has a large elasticity. The connecting spring 23 connects the support arm 18 and the connecting arm 17. Initially, the friction between the placement plate 21 and the stabilizer 20 does not cause the connecting spring 23 to undergo elastic deformation. Therefore, when the rotating arm 16 applies a tensile force to the connecting arm 17, support arm 18, positioning block 19, connecting spring 23, and placement plate 21, the connecting spring 23 does not undergo elastic deformation. This causes the connecting arm 17, positioning block 19, support arm 18, and placement plate 21 to move closer to the second heat-sealing block 10. During this process, the slide rail block 24 also slides within the slide rail groove 25. When the placement plate 21 moves to the connection groove 22 and the second heat-sealing block 10... When aligned, the slide block 24 and the slide groove 25 abut against the inner wall of the side closest to the vertical frame 2. At this time, the slide block 24 and the slide groove 25 cooperate to restrict the placement plate 21, so that the placement plate 21 can no longer move towards the side closer to the second heat sealing block 10 with the connecting arm 17. This ensures that the connecting groove 22 can always be aligned with the second heat sealing block 10. As the mounting block 6 continues to move downward, the connecting spring 23 is stretched and deformed. The mounting block 6 drives the first heat sealing block 8 to abut against the second heat sealing block 10 through the connecting groove 22, and presses the film between the first heat sealing block 8 and the second heat sealing block 10, thereby heat sealing the part of the film extending to the connecting groove.
[0032] Through the above process, manual heat sealing of the film is eliminated, avoiding burns to the arms from the first heat-sealing block 8 and the second heat-sealing block 10, thus improving safety and the safety and practicality of the heat-sealing machine's film fixing bracket. After heat sealing is completed, the starting cylinder 5 drives the mounting block 6 upward, thereby moving the first positioning seat 7, the first heat-sealing block 8, and the fixing arm 15 upward. The upward movement of the first heat-sealing block 8 releases its contact with the second heat-sealing block 10, thus ending the heat sealing work. During the upward movement of the fixing arm 15, the connecting spring 23 is first reset, and then the placement plate 21 is pushed to reset, thereby moving the heat-sealed film away from the second heat-sealing block 10, and further away from the second heat-sealing block 10 and the first heat-sealing block 8. This prevents the temperature of the second heat-sealing block 10 and the first heat-sealing block 8 from burning the worker's arms and also makes it easier to remove the heat-sealed film, thus increasing the practicality of the heat-sealing machine's film fixing bracket.
[0033] In this design, the sliding connection between the vertical rod 12 and the mounting cover 4 increases the stability of the connecting block 11 as it moves up and down.
[0034] In this design, as the cylinder 5 moves the connecting block 11 downward, it simultaneously moves the vertical rod 12, connecting rod 13, first positioning seat 7, first heat sealing block 8, and mounting block 6 downward. When the first heat sealing block 8 moves downward to abut against the second heat sealing block 10, the cylinder 5 moves the connecting block 11 downward by one to five centimeters. During this downward movement, the mounting block 6 pushes the stabilizing spring 14, causing it to deform between the connecting block 11 and the mounting block 6. Simultaneously, the release force of the stabilizing spring 14 pushes the mounting block 6, causing the first heat sealing block 8 to exert pressure on the second heat sealing block 10. This heat seals the film sandwiched between the first heat sealing block 8 and the second heat sealing block 10, preventing the film from being subjected to excessive pressure and ensuring the quality of the heat sealing.
[0035] In this solution, the cylinder 5 can not only drive the first heat-sealing block 8 to move downward so that the first heat-sealing block 8 and the second heat-sealing block 10 can heat-seal the film, but also drive the placement plate 21 to move back and forth, thereby moving the film away from or closer to the second heat-sealing block 10, which is more energy-efficient and improves the practicality of the film fixing bracket of the heat sealing machine.
[0036] In this design, the electric actuator 27 is a low-power electric actuator 27, whose thrust is only sufficient to position the membrane and is insufficient to cause injury to the human body.
[0037] In this design, during production and use, the thickness of the placement plate 21 is relatively thin and it is made of high-temperature resistant heat-insulating material. The distance between the lower surface of the placement plate 21 and the upper surface of 10 is relatively small.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
