Description

Technical Field

[0001] This utility model belongs to the field of silicone product processing technology, and specifically relates to a silicone seal cutting mechanism. Background Technology

[0002] Silica gel, also known as silica gel, is an amorphous substance. According to its properties, it is divided into two categories: inorganic silica gel and organic silica gel. Inorganic silica gel is produced by reacting sodium silicate with sulfuric acid. It has a porous structure and features such as adsorption and thermal stability. Organic silica gel contains Si-C bonds and mainly includes silicone rubber, silicone resin, etc. It can be desorbed and regenerated at high temperature and reused. The silicone seal cutting mechanism is a mechanism for cutting silicone seal strips.

[0003] However, traditional silicone seal cutting mechanisms are prone to damage to soft silicone materials due to hard contact or improper pressure control. When dealing with silicone parts of different thicknesses, manual adjustment of the holding or positioning components is required, which is cumbersome and has poor adaptability. During the cutting process, the material position cannot be stably limited, and silicone parts are prone to displacement and deformation, resulting in uneven cuts. At the same time, silicone parts are prone to lateral deviation during cutting, making it difficult to quickly and accurately match the cutting requirements. Ultimately, the deviation causes the cutting path to deviate from the preset trajectory, resulting in poor cut regularity and increasing the number of defective products caused by deviation, affecting cutting quality and work efficiency.

[0004] To address the problems mentioned in the background above, a silicone seal cutting mechanism is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a silicone seal cutting mechanism, which has the advantages of pressing and positioning and preventing deviation.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a silicone seal cutting mechanism, including a bracket, a sliding groove is provided on both sides of the front of the bracket, a slider is slidably connected inside the sliding groove, a spring is bolted to the front end of the bottom of the slider, a connecting block is bolted to the bottom of the spring, a pressure roller is bolted to the bottom of the connecting block, a worktable is bolted to both sides of the bottom of the bracket, a protective mechanism is provided on the opposite side of the two connecting blocks, and a cutting mechanism is provided at the top inside the bracket.

[0007] The above technical solution involves placing the silicone seal on the worktable. Under the pre-pressure of the spring, the pressure roller naturally adheres to the surface of the silicone seal. During the cutting process, if there are thickness differences in the silicone seal, the spring extends and retracts synchronously to adapt to the thickness changes, maintaining appropriate pressure on the silicone seal at all times. Throughout the process, the pressure roller not only stably presses down on the silicone seal to prevent it from shifting during cutting, but also avoids damaging the silicone seal through the flexible buffer of the spring, ensuring smooth cutting. It can hold the silicone seal, effectively preventing damage to the soft silicone material. The holding height can be automatically adjusted according to the thickness difference of the silicone seal, eliminating the need for manual adjustment of the fitting structure. It has strong adaptability, reduces material shifting or deformation during cutting, ensures the flatness of the cut, and improves the stability and efficiency of the cutting operation.

[0008] The present invention is further configured such that the protective mechanism includes a screw, the screw is rotatably connected to the opposite sides of the two connecting blocks, the surface of the screw is threaded with a screw sleeve, and the bottom of the screw sleeve is fixedly connected with a baffle.

[0009] The above technical solution employs a protective mechanism. When the screw is rotated, the threaded sleeve on the screw surface moves along the screw axis towards or away from the silicone part. Simultaneously, the threaded sleeve drives the bottom fixed baffle to move as well. By adjusting the distance between the baffle and the side of the silicone part, a lateral limit can be formed on the silicone part, preventing it from deviating during the cutting process. This targeted lateral limit effectively prevents material deviation during cutting, flexibly adapting to silicone parts of different widths. There is no need to replace the dedicated limiting component, and the adjustment operation is convenient. The stable limiting effect ensures accurate cutting paths, further improving cut regularity and reducing defective products caused by deviation.

[0010] The present invention is further configured such that the cutting mechanism includes an electric telescopic rod, which is embedded in the top of the bracket, and a blade holder is bolted to the bottom of the electric telescopic rod, and a blade is embedded in the bottom of the blade holder.

[0011] The above technical solution is adopted: by setting up a cutting mechanism, the electric telescopic rod extends and retracts vertically downwards or upwards. Its extension and retraction will synchronously drive the bottom blade holder to move up and down. The blade holder drives the blade to move, and the blade will contact and cut the silicone seal on the worktable to complete the cutting operation. After the cutting is completed, the electric telescopic rod retracts upwards, and the blade holder and blade return to their original positions, preparing for the next cutting.

[0012] The present invention is further configured such that the top of the screw sleeve is bolted to a slider two, and the front ends of the two sliders one on opposite sides are bolted to a groove two, and the interior of the groove two is slidably connected to the surface of the slider two.

[0013] By adopting the above technical solution, the movement of the screw sleeve can be limited by setting slider two and slide groove two.

[0014] The present invention is further configured such that sliders are welded to both sides of the tool holder, and grooves are provided on both sides of the inner wall of the support, and the interior of the grooves is slidably connected to the surface of the sliders.

[0015] By adopting the above technical solution, the movement of the tool holder can be limited by setting slider three and slide groove three.

[0016] The present invention is further configured such that a limit bolt is provided on the front side of the slider one.

[0017] The above technical solution is adopted: by setting a limit bolt, the movement of slider one can be limited.

[0018] The present invention is further configured such that a damper is sleeved inside the spring.

[0019] The above technical solution involves setting a damper to limit the spring and prevent it from continuously rebounding.

[0020] The present invention is further configured such that a handle is fixedly sleeved at the end of the screw away from the connecting block.

[0021] The above technical solution allows for easy rotation of the screw by incorporating a handle.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model can form a pressure on the silicone seal, effectively avoiding damage to the soft silicone material. It can automatically adjust the pressure height according to the thickness difference of the silicone part, without the need for manual adjustment of the adapter structure. It has strong adaptability, reduces material displacement or deformation during the cutting process, ensures the flatness of the cut, and improves the stability and efficiency of the cutting operation. 2. This utility model can effectively prevent material deviation during the cutting process by forming a targeted lateral limit on the silicone parts. It can be flexibly adapted to silicone parts of different widths and specifications without the need to replace the special limit components. The adjustment operation is convenient, and the stable limit effect can ensure the accuracy of the cutting path, further improve the regularity of the cut, and reduce the generation of defective products due to deviation.

A cutting mechanism is provided at the top inside the bracket 1. After the silicone sealant is placed on the worktable 11, the pressure roller 10 naturally adheres to the surface of the silicone sealant under the pre-pressure of the spring 8. During the cutting operation, if there is a thickness difference in the silicone sealant, the spring 8 synchronously extends and retracts to adapt to the thickness change, always maintaining appropriate pressure on the silicone sealant. Throughout the process, the pressure roller 10 not only stably presses down on the silicone sealant to prevent it from shifting during cutting, but also avoids damaging the silicone sealant through the flexible buffer of the spring 8, ensuring smooth cutting.

[0027] refer to Figure 4 The cutting mechanism includes an electric telescopic rod 15, which is embedded in the top of the bracket 1. The bottom of the electric telescopic rod 15 is bolted to a blade holder 16, and the bottom of the blade holder 16 is embedded with a blade 17. With the cutting mechanism, the electric telescopic rod 15 extends and retracts, extending downwards or retracting upwards in the vertical direction. Its extension and retraction will synchronously drive the blade holder 16 at the bottom to move up and down. The blade holder 16 drives the blade 17 to move. The blade 17 will contact and cut the silicone seal on the worktable 11 to complete the cutting operation. After the cutting is completed, the electric telescopic rod 15 retracts upwards, and the blade holder 16 and the blade 17 return to their original positions, preparing for the next cutting.

[0031] Example 2: refer to Figure 1 , Figure 2 A silicone sealant cutting mechanism includes a protective mechanism comprising a screw 12, which is rotatably connected to two connecting blocks 9 on opposite sides. A threaded sleeve 13 is threaded onto the surface of the screw 12, and a baffle 14 is fixedly connected to the bottom of the threaded sleeve 13. The baffle 14 is made of modified PP. When the screw 12 is rotated, the threaded sleeve 13 on the surface of the screw 12 moves towards or away from the silicone sealant along the axial direction of the screw 12. The threaded sleeve 13 synchronously drives the baffle 14 fixed at the bottom to move together. By adjusting the distance between the baffle 14 and the side of the silicone sealant, a lateral limit can be formed on the silicone sealant to prevent it from deviating during the cutting process.

[0034] Brief description of the usage process: After the silicone seal is placed on the workbench 11, the pressure roller 10 naturally adheres to the surface of the silicone seal under the pre-pressure of the spring 8. During the cutting operation, if there is a thickness difference in the silicone seal, the spring 8 will extend and retract synchronously to adapt to the thickness change, always maintaining appropriate pressure on the silicone seal. Throughout the process, the pressure roller 10 not only stably presses the silicone seal to prevent it from shifting during cutting, but also avoids damaging the silicone seal through the flexible buffer of the spring 8, ensuring smooth cutting. When the screw 12 is rotated, the threaded sleeve 13 on the surface of the screw 12 moves closer to or further away from the silicone seal along the axial direction of the screw 12. The threaded sleeve 13 synchronously drives the bottom fixed baffle 14 to move together. By adjusting the distance between the baffle 14 and the side of the silicone seal, the silicone seal can be laterally limited to prevent it from deviating during the cutting process.
