Description

Technical Field

[0001] This utility model belongs to the field of foam processing technology, and specifically relates to a silicone foam die-cutting device. Background Technology

[0002] Silicone foam is a high-performance cushioning material with a unique porous structure. In terms of cushioning performance, when subjected to heat and pressure, its foam structure effectively absorbs and disperses pressure. This pressure-dispersing characteristic prevents damage to the LCD panel due to excessive localized pressure during the LCD panel bonding process, such as avoiding indentations or circuit damage.

[0003] In terms of thermal properties, silicone foam exhibits excellent heat resistance. During hot pressing, it can withstand high temperatures, and its physical properties remain relatively stable under varying temperatures, preventing rapid aging, deformation, or loss of elasticity due to high temperatures. This allows it to maintain good cushioning performance under hot pressing conditions, continuously protecting the LCD panel.

[0004] Existing silicone foam typically requires die-cutting during production. However, existing die-cutting devices have certain defects and shortcomings. For example, Chinese patent CN216372437U discloses a silicone foam die-cutting device, which includes a mounting plate. A mounting frame is fixedly connected to the top center of the mounting plate, and a hydraulic rod is fixedly connected to the bottom center of the mounting frame. A connecting plate is fixedly connected to the telescopic end of the hydraulic rod. Several evenly distributed fixing blocks are provided at the bottom of the connecting plate. By setting up the hydraulic rod, connecting plate, fixing blocks, first spring, and stop blocks, the connecting plate and fixing blocks can be raised and lowered by the extension and retraction of the hydraulic rod, thereby raising and lowering the die-cutting blade to achieve die-cutting of the foam. The position of the stop blocks is fixed by the first spring, and the elasticity of the first spring ensures that the stop blocks contact the foam before the die-cutting blade and detach from the foam after the die-cutting blade, thus preventing the die-cut foam from getting stuck in the die-cutting blade and affecting the next die-cutting.

[0005] The aforementioned device employs multiple sets of die-cutting blades, aiming to process multiple foam grooves in a single operation, thus enabling multi-stage die-cutting. However, in actual die-cutting processes, this device exhibits significant limitations. It can only process products of a single specification. If a change in die-cutting shape is required, each die-cutting blade typically needs to be replaced. This means that during overall use, it cannot perform die-cutting of different sizes according to actual needs, exhibiting poor adaptability and versatility. This makes it extremely inconvenient when producing products of different specifications, as it cannot flexibly perform die-cutting of different sizes. Clearly, the existing technology has certain defects and shortcomings in this regard, and there is an urgent need to improve it to enhance its applicability and flexibility, meeting diverse production needs.

[0027] The die-cutting mechanism 6 includes a support arm 61, which is fixedly connected to one side of the back of the top frame 3. A frame base 62 is fixedly connected to the front end of the support arm 61. A first motor 63 is fixedly connected to the inner side of the frame base 62. A rotating shaft 64 is fixedly connected to the output end of the first motor 63 through the frame base 62. A cross 65 is fixedly connected to the bottom of the rotating shaft 64. Die-cutting components 66 are fixedly connected to the outer ends of the cross 65. The support legs 2 at the top of the base 1 provide stable support for the entire device. The transmission mechanism 4 inside the top frame 3, in conjunction with the positioning mechanisms 5 at both outer ends, realizes automatic feeding, displacement, and precise positioning of the silicone foam, ensuring the die-cutting process... The die-cutting mechanism 6 operates stably. The support arm 61 and frame 62 in the die-cutting mechanism 6 provide a stable mounting base for the first motor 63. The first motor 63 drives the rotating shaft 64 to rotate the cross 65, which in turn drives the die-cutting assembly 66 at the outer end of the cross 65 to work. This design allows the device to flexibly adjust the die-cutting blade 664 according to the needs of different product specifications during the die-cutting process, improving the adaptability and versatility of the device. At the same time, the die-cutting assembly 66 facilitates the replacement of the die-cutting blade 664, improving production efficiency. Overall, the device exhibits excellent performance in silicone foam processing, providing a strong guarantee for high-quality production.

[0028] refer to Figures 1-2 and Figures 4-5 The bottom of the frame 62 is fixedly connected with support frames 67 at equal intervals. Support rings 68 are fixedly installed at the bottom of the support frames 67. The rotating shaft 64 is rotatably connected to the inner side of the support rings 68. The support frames 67 provide stable support for the support rings 68, ensuring that the position of the support rings 68 is firm and reliable. The rotating shaft 64 is rotatably connected to the inner side of the support rings 68. The support rings 68 can play a good role in limiting and stabilizing the rotating shaft 64, ensuring that the rotating shaft 64 maintains a stable rotation trajectory during rotation, reducing shaking and deviation. This design makes the rotation of the rotating shaft 64 driven by the first motor 63 more stable, thereby ensuring that the cross 65 and the die-cutting assembly 66 can be precisely rotated and adjusted to adapt to the die-cutting requirements of different specifications of products, and improving the overall die-cutting accuracy and stability of the device.

[0029] refer to Figures 1-3The transmission mechanism 4 includes a conveyor belt 41, a mounting frame 42, and synchronous pulleys 43. The conveyor belt 41 is rotatably connected to both ends of the top frame 3. The synchronous pulleys 43 are rotatably connected to one side of the top frame 3, and there are two sets of synchronous pulleys 43. The mounting frame 42 is fixedly connected to the middle of the frame base 62 near the synchronous pulleys 43. A second motor 44 is fixedly connected to the outside of the mounting frame 42. The output end of the second motor 44 passes through the mounting frame 42 and is fixedly connected to one synchronous pulley 43. The synchronous pulleys 43 are connected to each other by a synchronous belt 45. The inner side of the synchronous pulley 43 is connected to the shaft of the conveyor belt 41 near the die-cutting mechanism 6. The positioning mechanism 5 includes a concave frame 51, which is fixedly connected to both ends of the outside of the top frame 3. A first electric push rod 52 is fixedly connected to the middle of the top of the concave frame 51. The output end of the first electric push rod 52 passes through the concave frame 51 and is fixedly connected to a positioning friction plate 53. In the transmission mechanism 4, the conveyor belt 41 passes through both ends of the top frame 3. The device automatically conveys silicone foam by rotating the ends. Two sets of synchronous pulleys 43 are connected by a synchronous belt 45 to ensure synchronous rotation. The second motor 44 on the mounting frame 42 provides power for the transmission. Its output end is connected to one of the synchronous pulleys 43, which drives the synchronous pulley 43 to rotate. In turn, the synchronous belt 45 drives the shaft inside the conveyor belt 41 to rotate, so that the two conveyor belts 41 rotate in the same direction. This enables efficient conveying and displacement of the silicone foam product, giving the device an automatic feeding and displacement function. The concave frame 51 of the positioning mechanism 5 is fixed at both ends of the outer side of the top frame 3 to provide stable support. The first electric push rod 52 at the top of the concave frame 51 can drive the positioning friction plate 53 to move down. When die-cutting is required, the positioning friction plate 53 is stably attached to the top of the silicone foam. After the conveyor belt 41 stops running, the two ends of the silicone foam are positioned to ensure stable die-cutting and improve the overall production and processing stability and accuracy of the device.

[0030] refer to Figures 1-2 and Figures 3-4The die-cutting assembly 66 includes a circular plate 661, which is fixedly connected to the outer end of the cross 65. A second electric push rod 662 is fixedly connected to the top of the circular plate 661. The output end of the second electric push rod 662 passes through the circular plate 661 and is fixedly connected to a mounting member 663. Die-cutting blades 664 are fixedly connected at equal intervals to the bottom of the mounting member 663. The mounting member 663 includes a bottom rail 6631, which is fixedly connected to the bottom output end of the second electric push rod 662. A sliding joint is slidably connected inside the bottom rail 6631. The bottom of the movable plate 6632 and the sliding plate 6632 is fixedly connected to the die-cutting plate 6633. The die-cutting blades 664 are fixedly connected to the bottom of the die-cutting plate 6633 at equal intervals. Both ends of the top of the bottom rail 6631 are threaded with hand-tightening screws 6634. The bottom of the hand-tightening screws 6634 passes through the bottom rail 6631 and the top of the sliding plate 6632 and is threaded. The overall cross-sectional shape of the internal cavity of the bottom rail 6631 is convex. The overall cross-sectional shape of the sliding plate 6632 is also convex. The base 1 and the top frame The outer corners of component 3 are all rounded. The circular plate 661 in the die-cutting assembly 66 is fixedly connected to the outer end of the cross 65, providing stable support for the subsequent structure. The second electric push rod 662 at the top of the circular plate 661 can precisely control the movement of the mounting component 663 at the output end, thereby driving the die-cutting blade 664 to perform die-cutting processing on the silicone foam. The bottom rail 6631 of the mounting component 663 cooperates with the sliding plate 6632. The internal cavity of the bottom rail 6631 and the overall cross-sectional shape of the sliding plate 6632 are convex. This design can effectively prevent The anti-slip plate 6632 can sway or shift within the bottom rail 6631, ensuring the stability and accuracy of the die-cutting process. When it is necessary to replace the die-cutting blade 664, the sliding plate 6632 can be easily pulled out and installed by adjusting the hand-tightening screw 6634, which facilitates quick replacement of die-cutting blades 664 of different specifications and improves production efficiency. In addition, the outer corners of the base 1 and the top frame 3 are set to be rounded, which not only increases the safety of the device and prevents personnel from being accidentally injured during operation, but also makes the device look more beautiful and smooth.

[0031] Operating Principle and Advantages: By setting up the die-cutting mechanism 6, this device can exhibit excellent performance during actual use. Specifically, the second electric push rod 662 can be activated. When the second electric push rod 662 starts working, it will forcefully push the mounting part 663 downward. As the mounting part 663 moves downward, the die-cutting plate 6633 connected to the bottom of the mounting part 663 and the die-cutting blade 664 at its bottom will also move downward synchronously. At this time, the die-cutting blade 664 can perform precise die-cutting processing on the silicone foam. During the die-cutting process, if it is necessary to cut product shapes of different specifications, the first motor 63 can be activated. The first motor 63 can drive the rotating shaft 64 between the support frame 67 and the support ring 6. The internal rotation of 8 is stable, which in turn drives the cross 65 to rotate. The rotation of the cross 65 drives the bottom die-cutting assembly 66 to rotate accordingly. During use, each die-cutting assembly 66 is equipped with a die-cutting blade 664 of different specifications. Driven by the rotation of the first motor 63, the die-cutting blades 664 of different specifications can be flexibly rotated and moved to the middle position of the two conveyor belts 41. In this way, during the production process, each die-cutting blade 664 can be flexibly adjusted according to actual needs, which greatly improves the adaptability of the device during the overall use. At the same time, it also significantly improves the versatility of the device in the overall production process, and can better meet the processing needs of products of different specifications.

[0032] By setting up the die-cutting assembly 66, the device becomes more convenient and efficient during use. When it is necessary to replace the die-cutting blade 664, the hand-tightening screw 6634 can be adjusted and turned upwards. Specifically, by adjusting the hand-tightening screw 6634 to rotate upwards, when the hand-tightening screw 6634 is disengaged from the bottom rail 6631, the sliding plate 6632 can be easily pulled out from inside the bottom rail 6631. In this way, each die-cutting blade 664 can be easily removed. Then, the die-cutting plate 6633 with different specifications of die-cutting blades 664 can be taken out. Then, the sliding plate 6632 is slid back into the bottom rail 6631 and securely installed by the hand-tightening screw 6634. This design facilitates the quick replacement of the die-cutting blade 664, greatly improves the convenience of the device during use, and brings higher efficiency to the production and processing process.

[0033] By setting the transmission mechanism 4 and positioning mechanism 5 to cooperate with each other, the device is made more stable and reliable during use. Specifically, silicone foam can be placed on top of conveyor belt 41. At this time, by starting the second motor 44, the second motor 44 can drive one synchronous pulley 43 to rotate. After the synchronous pulley 43 rotates, it can drive the other synchronous pulley 43 to rotate through the synchronous belt 45. When both synchronous pulleys 43 start to rotate, the synchronous belt 45 can drive the shafts inside the two conveyor belts 41 inside the top seat to rotate. As the shafts of the conveyor belts 41 rotate, the synchronous belt 45 can then drive the two conveyor belts 41 to rotate in the same direction. At this time, the silicone foam on top of the conveyor belt 41 can be processed. The device automatically feeds and moves materials, enabling it to automatically load and move materials. If die-cutting is required during the loading and moving process, the first electric push rod 52 can drive the positioning friction plate 53 to move downwards. After the positioning friction plate 53 moves downwards, it can stably fit against the top of the silicone foam. At this time, the conveyor belt 41 stops running, and both ends of the silicone foam can be positioned. Under these circumstances, the die-cutting mechanism 6 can be started to perform die-cutting. The positioning friction plate 53 clamps and positions the materials, ensuring stability during the die-cutting process. This greatly improves the overall stability of the device during production and provides a strong guarantee for high-quality production.
