Description

Technical Field

[0001] This invention relates to the field of cutting device technology, specifically to a multi-position synchronous cutting device for hot-pressing silicone composite strips and its usage method. Background Technology

[0002] Silicone composite tape is a strip-shaped functional material made of silicone as the base material and compounded with other materials. It combines the high temperature resistance, chemical corrosion resistance, flexibility and electrical insulation of silicone with the mechanical strength or special functions of reinforcing materials. It is widely used in electronic and electrical insulation, sealing protection, electromagnetic shielding, high temperature insulation and industrial equipment cushioning.

[0003] The multi-position synchronous cutting device for hot-pressing silicone composite strip is a processing equipment specifically designed for the hot-pressing molding process of this material. Its core function is to use a multi-station synchronous cutting mechanism to accurately cut a wide silicone composite strip into multiple pieces of specific sizes and shapes according to the mold requirements in one go, thereby achieving precise control of the amount of material fed and batch consistency. This significantly improves the material preparation efficiency before hot-pressing vulcanization, reduces the error and time consumption of manual piece-by-piece cutting, and ensures the stable quality of subsequent hot-pressed products.

[0004] When the cutting device cuts silicone composite strips, the silicone material itself is sticky, and adjacent pieces after cutting are prone to sticking together. When separating them, edge damage, surface tearing or residual debris can easily occur, which directly affects the appearance quality and dimensional accuracy of the subsequent hot-pressed products. Therefore, in order to solve the above problems, a multi-position synchronous cutting device for hot-pressed silicone composite strips and its usage method are proposed. Summary of the Invention

A guide rod and a reset elastic element are fixedly connected inside the internal mounting cavity. A sliding adjustment seat is slidably connected to the outside of the guide rod. The end of the reset elastic element abuts against the sliding adjustment seat. A magnetic separation head is rotatably connected to the inside of the sliding adjustment seat. The strip support and conveying mechanism includes a support base with a support seat fixedly connected to the top. A fixed magnetic block is fixedly connected to one side of the support seat. The magnetic separation head and the fixed magnetic block are magnetically attracted to each other.

[0008] As a further optimization of the present invention, the mounting frame assembly includes a frame body, the bottom end of which is fixedly connected to the equipment base, and an assembly groove and an installation groove are provided on the inner side of the frame body.

[0009] As a further optimization of the present invention, the following features are provided: a transmission mounting base is fixedly connected to the front end of the main frame body; a drive motor is fixedly connected to one side of the transmission mounting base; the end of the drive motor spindle is fixedly connected to the transmission disk; and the transmission disk on the left end is rotatably connected to the transmission mounting base on the left end.

[0010] As a further optimization of the present invention, the frame body has a threaded hole at one end, a locking bolt is threadedly connected to the inner side of the threaded hole, a locking block is threadedly connected to the outer side of the locking bolt, and both ends of the locking block have beveled surfaces.

[0011] As a further optimization of the present invention, wherein: a rotating seat slides into the inner side of the mounting groove, a bearing is fixedly connected to the inner side of the rotating seat, a clamping seat slides into the inner side of the mounting groove, a clamping groove is provided on the inner side of the clamping seat, and the clamping seat and the rotating seat are in contact.

[0012] As a further optimization of the present invention, one end of the locking block is inserted into the pressing groove, and the slope end face is in contact with the pressing groove.

[0013] As a further optimization of the present invention, the inner side of the bearing is connected to a tool mounting shaft, and a cutting tool and a retaining ring are fixedly connected to the outer side of the tool mounting shaft, with the side of the retaining ring fitting against the side of the inner ring of the bearing.

[0014] As a further optimization of the present invention, the cutting tool and the cutting limiting roller are close to each other, the cutting limiting roller is installed inside the rotating seat at the lower end, and a retaining ring is installed on the outer side of the cutting limiting roller.

[0015] As a further optimization of the present invention, the support base is rotatably connected to a rotating seat on its inner side, the rotating seat is fixedly connected to a recessed hole on its outer side, the recessed hole is rotatably connected to a roller, and the recessed hole and the roller are arranged in a circumferential array around the rotating seat.

[0016] A method for using a multi-position synchronous cutting device for hot-pressed silicone composite strips;

[0017] S1: During equipment assembly, install rotating seats in the two mounting slots of the main frame body, insert the two ends of the tool mounting shaft into the bearings and make the retaining ring fit with the bearings. First, slide the upper rotating seat and the clamping seat into the upper mounting slot in sequence. Then, operate the assembly of the lower rotating seat, the cutting limit roller and the clamping seat from the assembly slot. After fixing the lower part, align the slope of the locking block with the clamping mating groove and insert it. Install the locking bolt threaded into the threaded hole, tighten the locking bolt to squeeze the locking block. Through the slope structure, squeeze the clamping mating groove to make the clamping seat fit with the rotating seat, and complete the overall assembly and fixing of the cutting tool and the cutting limit roller.

[0018] S2: During the cutting operation, the roll of silicone composite material is drawn out and passed between the cutting blade and the cutting limit roller. The cutting blade completes the cutting. The friction generated by the material conveying drives the cutting blade and the cutting limit roller to rotate relative to the rotating seat through the bearing. The cut material is conveyed to the roller and finally wound on the automatic take-up roller, relying on the traction power of the take-up roller.

[0019] S3: During the material strip separation operation, the drive motor drives the transmission disc and internal linkage structure to rotate. When the magnetic separation head approaches the roller, the two work together to squeeze and position the material strip. The friction of the material strip drives the roller and rotating seat to rotate. At the same time, the magnetic separation head rotates within the sliding adjustment seat without affecting the material strip conveying. When the magnetic separation head is magnetically aligned with the fixed magnetic block, it pulls the sliding adjustment seat along the guide rod and squeezes the reset elastic element to store and reset. The magnetic separation head moves with the sliding adjustment seat to push the material strip. With the rotation of the roller, the two sections of the cut material strip move away from each other, completing the material strip separation operation.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the cutting blade and cutting limit roller are set, and the equipment adopts a modular and detachable installation structure, which allows for quick disassembly and replacement of the core cutting components. The components can be replaced in time after wear, ensuring the cutting accuracy and effectiveness of the silicone composite strip, and maintaining the stable cutting performance of the equipment in the long term.

[0022] 2. In this invention, by setting a rotating seat and bearing, the equipment relies on the friction of the conveying belt to realize the adaptive rotation of the cutting component, and completes continuous cutting operations in conjunction with the automated winding structure. No manual assistance is required for cutting operations, which improves the cutting efficiency of silicone composite material belts and ensures the stability of batch cutting operations to meet the needs of industrial continuous production.

[0023] 3. In this invention, the device can accurately position and automatically separate the cut strip by means of the sliding adjustment seat, magnetic separation head and roller, avoiding the problem of material sticking caused by the stickiness of silicone material, eliminating the problems of edge damage, surface tearing and residual debris that occur during the separation process, improving the quality of the finished strip and ensuring the processing quality of subsequent hot pressing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-12 The present invention provides a technical solution:

[0045] A multi-position synchronous cutting device for hot-pressed silicone composite strip and its usage method include a base 1, a mounting frame assembly 2, and a cutting and positioning assembly 3. A cutting and positioning roller 4 is installed inside the cutting and positioning assembly 3. A separation transmission mechanism 5 is installed at the front end of the mounting frame assembly 2. A strip support and conveying mechanism 6 is installed on one side of the mounting frame assembly 2. The separation transmission mechanism 5 includes a transmission disk 51. An internal mounting cavity 52 is opened inside the transmission disk 51. A guide rod 53 and a reset elastic element 54 are fixedly connected inside the internal mounting cavity 52. ​​A sliding adjustment seat 55 is slidably connected to the outside of the guide rod 53. The end of the reset elastic element 54 abuts against the sliding adjustment seat 55. A magnetic separation head 56 is rotatably connected to the inside of the sliding adjustment seat 55. The strip support and conveying mechanism 6 includes a support base 61. A support seat 65 is fixedly connected to the top of the support base 61. A fixed magnetic block 66 is fixedly connected to one side of the support seat 65. The magnetic separation head 56 and the fixed magnetic block 66 are magnetically attracted to each other.

[0046] As a further implementation of this solution, the mounting frame assembly 2 includes a frame body 21, the bottom of which is fixedly connected to the equipment base 1. The frame body 21 has an assembly slot 22 and an installation slot 23 on its inner side. With the above configuration, this structure can provide a stable installation reference and assembly space for each subsequent cutting and separation component. The partitioned slot structure can realize the precise positioning and installation of each functional component.

[0047] As a further implementation of this solution, a transmission mounting base 24 is fixedly connected to the front end of the frame body 21. A drive motor 25 is fixedly connected to one side of the transmission mounting base 24. The end of the main shaft of the drive motor 25 is fixedly connected to the transmission disk 51. The left end of the transmission disk 51 is rotatably connected to the left end of the transmission mounting base 24. Through the above settings, this transmission connection structure can realize stable power transmission, provide continuous and stable power support for the automatic material belt separation mechanism, ensure the continuous and stable operation of the separation structure, eliminate the need for manual intervention, and improve the automation level of the equipment.

[0048] As a further implementation of this solution, a threaded hole 26 is provided at one end of the frame body 21. A locking bolt 27 is threadedly connected to the inner side of the threaded hole 26, and a locking block 28 is threadedly connected to the outer side of the locking bolt 27. Both ends of the locking block 28 are provided with slopes 29. Through the above settings, the threaded connection structure can achieve precise adjustment and locking of the locking bolt 27 and the locking block 28. With the slopes 29, the extrusion limit force can be controllably adjusted to meet the assembly and fixing requirements of different specifications of components.

[0049] As a further implementation of this solution, a rotating seat 33 slides into the inner side of the mounting groove 23, and a bearing 35 is fixedly connected to the inner side of the rotating seat 33. A clamping seat 36 slides into the inner side of the mounting groove 23, and a clamping groove 37 is provided on the inner side of the clamping seat 36. The clamping seat 36 and the rotating seat 33 fit together. Through the above settings, a sliding embedded assembly structure is adopted, which can realize the quick disassembly and assembly and precise fitting and positioning of each connecting component, ensure the structural stability of the component after assembly, effectively reduce the probability of component loosening and displacement during the cutting operation, and ensure the stability of the cutting operation.

[0050] As a further implementation of this solution, one end of the locking block 28 is inserted into the pressing groove 37, and the end face of the slope 29 is in contact with the pressing groove 37. Through the above arrangement, the pressing seat 36 and the rotating seat 33 can be tightly fitted and locked by the pressing and squeezing fit of the slope 29 and the pressing groove 37, which can effectively fix the assembly position of the cutting component, prevent displacement and shaking of the cutting component during operation, and further ensure the cutting accuracy of the silicone composite strip.

[0051] As a further implementation of this solution, a tool mounting shaft 32 is inserted into the inner side of the bearing 35, and a cutting tool 31 and a retaining ring 34 are fixedly connected to the outer side of the tool mounting shaft 32. The side of the retaining ring 34 fits against the side of the inner ring of the bearing 35. Through the above arrangement, the insertion and fitting structure can achieve precise positioning and installation of the cutting tool 31, ensure the tightness and coaxiality of the component connection, and at the same time, it can disassemble and replace worn parts to continuously maintain excellent cutting performance.

[0052] As a further implementation of this solution, the cutting blade 31 and the cutting limiting roller 4 are close to each other. The cutting limiting roller 4 is installed inside the rotating seat 33 at the lower end, and the retaining ring 34 is installed on the outer side of the cutting limiting roller 4. Through the above settings, the cutting blade 31 and the cutting limiting roller 4, which are arranged correspondingly at the top and bottom, form a precise cutting fit structure, which can stably align and cut the silicone composite strip.

[0053] As a further implementation of this solution, a rotating seat 62 is rotatably connected to the inner side of the support base 61, and a recessed hole 63 is fixedly connected to the outer side of the rotating seat 62. A roller 64 is rotatably connected inside the recessed hole 63. The recessed hole 63 and the roller 64 are arranged in a circumferential array around the rotating seat 62. Through the above arrangement, the rotating support structure arranged in a circumferential array can realize the smooth conveying and flexible support of the cut strip, reduce friction damage during strip conveying, and adapt to continuous cutting operations.

[0054] Workflow: During assembly, rotating seats 33 are installed on both mounting slots 23 of the same frame body 21. The two ends of the tool mounting shaft 32 are inserted into the bearings 35 until the retaining ring 34 is in contact with the bearings 35. The rotating seat 33 first slides into the upper mounting slot 23, and then the clamping seat 36 slides into the mounting slot 23. When installing another rotating seat 33 into the lower mounting slot 23, the lower rotating seat 33 is first moved out of the assembly slot 22. The two ends of the cutting limit roller 4 are inserted into the bearings 35, and then the lower rotating seat 33 slides into the mounting slot 23. The other clamping seat 36 slides into the lower mounting slot 23. The process is then guided by hand. Holding the lower rotating seat 33 and pressing seat 36, align the slope 29 of the locking block 28 with the two pressing grooves 37 and insert it. The locking bolt 27 is threaded into the threaded hole 26. When operating the locking bolt 27, the locking block 28 is squeezed by the locking bolt 27, which in turn squeezes the two pressing seats 36. The pressing of the pressing grooves 37 by the slope 29 makes the pressing seats 36 close to the rotating seat 33, thus realizing the installation of the cutting tool 31 and the cutting limit roller 4. This installation method allows the cutting tool 31 and the cutting limit roller 4 to be replaced when they are worn to a certain extent during use, ensuring the effectiveness of the cutting tool 31 in cutting silicone composite material strips.

[0055] When cutting silicone composite strip, the end of the rolled silicone composite strip is led forward and passes between the cutting blade 31 and the cutting limit roller 4. During this process, the cutting blade 31 cuts the silicone composite strip. The friction between the silicone composite strip and the cutting blade 31 and the cutting limit roller 4 causes the cutting blade 31 and the cutting limit roller 4 to be rotatably connected to the rotating seat 33 through the bearing 35. After cutting, the silicone composite strip is led forward and the two ends of the led-out silicone composite strip are placed on the roller 64. Then, the cut silicone composite strip is wound around the outside of the existing automatic take-up roller. In this way, the silicone composite strip is cut during the process of the automatic take-up roller winding the silicone composite strip.

[0056] When separating the cut silicone composite strip, the drive motor 25 is started to drive the transmission disk 51 to rotate. The rotation of the transmission disk 51 drives the internal structure to rotate simultaneously. During this process, when the magnetic separation head 56 approaches the roller 64, the silicone composite strip is squeezed by the cooperation between the magnetic separation head 56 and the roller 64, achieving the effect of temporarily positioning the silicone composite strip. At the same time, under the friction between the silicone composite strip and the roller 64 and the magnetic separation head 56, the roller 64 drives the rotating seat 62 to rotate. The magnetic separation head 56 rotates inside the sliding adjustment seat 55, which does not affect the normal conveying of the silicone composite strip. When the magnetic separation head 56 is aligned with the fixed magnetic block 66, the silicone composite strip is further separated by the magnetic separation head 56 and the fixed magnetic block 66. The magnetic attraction of the fixed magnetic block 66 causes the magnetic separation head 56 to move the sliding adjustment seat 55. The sliding adjustment seat 55 slides outside the guide rod 53 and presses against the reset elastic element 54. The reset elastic element 54 resets the sliding adjustment seat 55. As the magnetic separation head 56 moves with the sliding adjustment seat 55, it pushes the silicone composite strip. The friction between the silicone composite strip and the roller 64 causes the roller 64 to rotate inside the concave hole 63. At this time, the two silicone composite strips move away from each other, thus preventing the cut silicone composite strips from sticking together due to their stickiness. This would prevent edge damage, surface scratches, or residual debris during separation, ensuring the quality of subsequent processing.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
