[0007] By adopting the above technical solution, the die-cutting table is provided with a knife hole, and the die-cutting tool extends from the top surface of the die-cutting table from the knife hole, ensuring that the die-cutting tool can accurately cut the foam. The die-cutting frame arranged above the die-cutting table is connected to a pressing device, which includes a pressing belt, a pressing assembly and a conveying assembly. The pressing assembly pushes the pressing belt toward the die-cutting table, effectively preventing the foam from "bouncing" and shaking during the cutting process, and improving the accuracy of the die-cutting position. The conveying assembly drives the pressing belt to rotate, ensuring the stability and continuity of the foam during the entire die-cutting process, and improving production efficiency and product quality.

[0008] Preferably, the conveying assembly comprises a conveying wheel and a conveying driving member, the conveying wheel is tightly pressed against the inner side of the pressing belt, and the conveying driving member is connected to the die-cutting frame and is used to drive the conveying wheel to rotate.

[0009] By adopting the above technical solution, the pressing belt can move stably and continuously, ensuring the stability of the foam during the die-cutting process. Specifically, a damping layer can be added to the inner side of the pressing belt, so that the transmission of the pressing belt can be more reliable, avoiding the die-cutting position deviation caused by the slipping of the pressing belt. At the same time, the setting of the conveying drive can accurately control the rotation speed and force of the conveying wheel, further improving the die-cutting accuracy and efficiency.

[0010] Preferably, the pressing assembly includes a pressing wheel and a pressing drive component, the pressing wheel abuts against the inner side of the pressing belt, the pressing drive component is connected between the pressing wheel and the die-cutting frame and is used to push the pressing wheel toward the die-cutting table, and the driving shaft of the pressing drive component is rotatably connected to the pressing wheel.

[0011] By adopting the above technical solution, the pressing wheel can fit tightly inside the pressing belt, ensuring that the pressing belt is always in a good tension state during operation, avoiding the problem of unstable foam compression caused by relaxation. The pressing drive can flexibly adjust the position and pressure of the pressing wheel through the rotation connection between its drive shaft and the pressing wheel, ensuring that the pressing belt is evenly applied, and improving the stability and accuracy of the foam during the die-cutting process.

The tensioning driving member is connected between the die-cutting frame and the tensioning wheel and is used to press the tensioning wheel against the inner side of the pressing belt. The tensioning wheel and the tensioning driving member are rotationally connected.

[0013] By adopting the above technical solution, the tensioning assembly can effectively maintain the tension state of the pressing belt, and prevent the unstable foam cutting problem caused by the loosening of the pressing belt. Specifically, the tensioning wheel is in close contact with the inner side of the pressing belt, and through the action of the tensioning driving member, it is ensured that the pressing belt is always in an appropriate tension state, so that the pressing belt can stably press down the foam, improving the die-cutting accuracy and quality.

[0014] Preferably, a sleeve is fixedly connected to the driving shaft of the tensioning drive member, a sliding rod is slidably arranged inside the sleeve, the tensioning wheel is connected to the tensioning drive member through a rotational connection with the sliding rod, and an elastic member is arranged between the sliding rod and the sleeve, and the elastic member is used to press the tensioning wheel against the inner side of the pressing belt.

[0015] By adopting the above technical solution, the design can ensure that the tension wheel always fits tightly against the inner side of the pressure belt, effectively preventing the pressure belt from loosening, improving the stability and cutting accuracy of the foam during the die-cutting process, and reducing the die-cutting error caused by the loose pressure belt. At the same time, the design of the elastic part allows the tension to be automatically adjusted according to the actual working conditions, further improving the reliability and applicability of the equipment.

[0016] Preferably, a plurality of mounting grooves are rotatably provided on the surface of the die-cutting table, and power-assisting rollers are rotatably provided in the plurality of mounting grooves, and the tops of the plurality of power-assisting rollers extend out of the mounting grooves.

[0017] By adopting the above technical solution, the several mounting grooves and power-assisting rollers arranged on the surface of the die-cutting table can effectively reduce the friction resistance of the foam during the transportation process, improve the smoothness and stability of the foam transportation, avoid deformation or damage of the foam caused by friction, and ensure the die-cutting accuracy and quality.

[0018] Preferably, a dust suction assembly is provided below the die-cutting table near the knife hole, and the dust suction assembly includes a dust suction bin, a dust suction pipe and a dust suction fan. The dust suction bin is connected to the die-cutting table, and a bottom portion of the dust suction pipe is provided at the top near the knife hole and is connected to the dust suction bin. The dust suction bin has an exhaust port, and a filter is provided at the exhaust port. The dust suction fan is located inside the dust suction bin and connected to the bottom of the dust suction pipe.

[0019] By adopting the above technical solution, a dust collection component is set under the die-cutting table near the knife hole, which can effectively absorb the debris and dust generated during the die-cutting process, keep the working environment clean, and prevent these impurities from having adverse effects on subsequent processing. Specifically, the dust collection component includes a dust collection bin, a dust collection pipe and a dust collection fan. The dust collection bin is connected to the die-cutting table. The top of the dust collection pipe is set near the knife hole, and the bottom is connected to the dust collection bin, ensuring the high efficiency of the dust collection effect.

[0021] By adopting the above technical solution, the design of the main air duct and the branch air duct can effectively guide the airflow, so that the airflow blows from the outlet of the branch air duct to the power-assisting edge of the power-assisting roller, so that the power-assisting roller rotates along the foam conveying direction. This not only reduces the resistance of the foam during the conveying process, but also improves the conveying stability and efficiency of the foam, ensuring the accuracy and quality of the die-cutting process.

[0022] Preferably, a filter ball holder is rotatably arranged inside the dust collector bin near the exhaust port, the filter ball holder includes a plurality of arc-shaped push plates, the filter screen is connected between the plurality of push plates, the plurality of arc-shaped push plates form a spherical skeleton, the air outlet direction of the dust collector pipe can blow the plurality of push plates to realize the rotation of the filter ball holder, bristles are arranged at the exhaust port, the bristles are against the filter screen, and a rebound part is arranged between the bristles and the exhaust port.

[0023] By adopting the above technical solution, the rotation of the filter ball holder can effectively prevent dust from clogging the filter, thereby improving the dust collection efficiency and the service life of the filter. Specifically, the rotation of the filter ball holder causes the dust attached to the filter to fall off due to the centrifugal force, thus avoiding the problem of the filter being clogged due to long-term use, thereby ensuring the long-term stable operation of the dust collection assembly. At the same time, the bristles arranged at the exhaust port can continuously clean the surface of the filter when the filter ball holder rotates, further enhancing the self-cleaning ability of the filter. The design of the rebound member ensures that the bristles always maintain good contact with the filter, thereby improving the cleaning effect.

[0024] In a second aspect, the present application provides a silicone foam processing method, which adopts the following technical solution: A silicone foam processing method, before the foam is conveyed to a die-cutting tool, a pressing belt presses down the foam on both sides of the die-cutting tool, and then the die-cutting tool cuts the extruded foam.

[0025] By adopting the above technical solution, the problem of "bouncing" or shaking caused by the light texture of the foam during the slicing process can be effectively solved, ensuring the stability and accuracy of the foam during slicing. The pressing belt presses down the foam on both sides of the die-cutting tool, which can significantly reduce the movement of the foam during the slicing process and improve the slicing quality. After slicing, as the foam continues to be transported, it is no longer squeezed by the pressing belt, which helps to ensure the smooth transportation and collection of the subsequent foam.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The pressing device presses down the foam on both sides of the die-cutting tool through the pressing belt, which effectively reduces the "bouncing" or shaking of the foam during the die-cutting process and significantly improves the accuracy and stability of the die-cutting position; 2. The conveying assembly drives the pressing belt to rotate through the conveying wheel, ensuring that the pressing belt can apply pressure to the foam evenly and stably, further enhancing the stability during the die-cutting process; 3. The tensioning assembly keeps the tension of the press belt through the tensioning wheel and the tensioning drive, avoiding the problem of inconsistent die-cutting caused by loose press belt and improving the consistency and reliability of die-cutting.

For this reason, the present application mainly adopts the following scheme to achieve the effect of improving the die-cutting accuracy and quality. The present application is further described in detail below.

The die-cutting tool 12 is arranged below the die-cutting table 1 through a bracket and the actual position of the tool can be adjusted up and down. The tool can extend from the knife hole 120 to the top surface of the die-cutting table 1 to cut the foam.

[0032] Reference Figure 1 and Figure 2 The pressing device includes a pressing belt 2, a pressing assembly 3, a conveying assembly 4 and a tensioning assembly 5.

The conveying assembly 4 is located above the die-cutting frame 14 and is used to drive the pressing belt 2 to rotate. Two tensioning assemblies 5 are provided and are located on both sides of the die-cutting frame 14 in the horizontal direction, respectively, to maintain the tension between the pressing belt 2 and each assembly.

[0033] Specific: Reference Figure 3, the pressing assembly 3 includes a pressing wheel 31 and a pressing drive 32. The pressing drive 32 is a cylinder and is connected to the die-cutting frame 14. The driving shaft of the pressing drive 32 is rotatably connected to the pressing wheel 31. The pressing wheel 31 abuts against the inner side of the pressing belt 2. In this embodiment, the pressing wheel 31 is made of rubber material to increase the friction with the pressing belt 2 and ensure the stable movement of the pressing belt 2. In other embodiments, the pressing wheel 31 can also be made of metal material, and a layer of wear-resistant material is plated on the surface to extend the service life. In this embodiment, the pressing assembly 3 is set to 5 groups. The actual number of pressing assemblies 3 used can be adjusted according to the thickness of the foam during the actual processing. The pressing drive 32 pushes the pressing wheel 31 toward the die-cutting table 1, thereby driving the pressing belt 2 to press down the foam, so as to compress and tighten the foam on both sides of the tool, thereby improving the stability of the foam in the subsequent cutting process.

[0034] Reference Figure 4 The conveying assembly 4 includes a conveying wheel 41 and a conveying driving member 43. The conveying driving member 43 is connected to the die-cutting frame 14.

A sliding rod 54 is slidably inserted inside the sleeve 53. The tensioning wheel 51 is connected to the tensioning driving member 52 by rotating with the end of the sliding rod 54. An elastic member 55 is also provided between the sleeve 53 and the sliding rod 54. In addition to the tensioning driving member 52 being able to actively retract to adjust the degree of tightness of the tensioning wheel 51 on the inner side of the pressing belt 2, the elastic member 55 can also be used to provide a certain fault tolerance rate, so that the tensioning assembly 5 is not easy to cause damage to the unwinding belt. In addition, when the foam is locally too thick, causing the pressing assembly 3 to passively rise, the tensioning assembly 5 can also use the elastic member 55 to support the pressing belt 2 in the horizontal direction with the two tensioning wheels 51 respectively, thereby maintaining the effectiveness of the tensioning state. In this embodiment, the tension wheel 51 is made of stainless steel with a smooth surface to reduce wear with the pressing belt 2. In other embodiments, the tension wheel 51 can be made of polyurethane to increase friction with the pressing belt 2 to prevent slipping.

In this embodiment, the power-assist rollers 6 can be made of nylon. In other embodiments, the power-assist rollers 6 can also be made of ceramic material, which has high hardness and wear resistance. The surface of the power-assist rollers 6 is also provided with a plurality of power-assist ridges 61, which can intermittently "lift" the bottom of the foam by a small amplitude as the power-assist rollers 6 rotate, so that the foam is not easily stuck in the mounting grooves 60 during the transportation of the foam, so as to better guide the foam forward.

[0037] Reference Figure 6 and Figure 8 A dust suction assembly 7 is also provided at a position near the knife hole 120 below the die-cutting table 1. The dust suction assembly 7 includes a dust suction bin 71, a dust suction pipe 72 and a dust suction fan 73.

The bottom of the dust suction pipe 72 is connected to the dust suction bin 71, and the dust suction fan 73 is installed at the bottom of the dust suction pipe 72. In this embodiment, the dust suction fan 73 adopts a centrifugal fan, which has a high dust suction efficiency. Another optional solution is that the dust suction fan 73 can adopt an axial flow fan, which is smaller in size and easy to install.

[0038] Reference Figure 7 and Figure 8The top corner of the dust collection bin 71 also has an exhaust port 74. The interior of the die-cutting table 1 is provided with a transversely arranged main air duct 81, which is connected to the exhaust port 74. A plurality of branch air ducts 82 are extended from the top of the main air duct 81. The plurality of branch air ducts 82 correspond to and are connected to a plurality of mounting grooves 60 one by one. The air outlet direction of the branch air duct 82 can blow the assisting edge 61 to realize the assisting roller 6 to rotate along the conveying direction of the foam, thereby further assisting the foam conveying.

[0039] The air duct inside the die-cutting station 1 can be implemented in a variety of ways. For example, the main air duct 81 and the branch air duct 82 can use PVC pipes, which have good flexibility and corrosion resistance. Another optional solution is that the main air duct 81 and the branch air duct 82 can use aluminum alloy pipes, which have higher strength and longer service life.

[0040] Reference Figure 8 A filter ball frame is rotatably arranged inside the dust collecting bin 71 near the air outlet 74. The filter ball frame includes a plurality of arc-shaped push plates 75. A filter screen 76 is installed between the plurality of push plates 75. The plurality of arc-shaped push plates 75 form a cylindrical frame, and the push plates 75 at least partially protrude from the frame. The air outlet direction of the dust collecting pipe 72 can blow the plurality of push plates 75 to realize the rotation of the filter ball frame.

[0041] Reference Figure 8 and Fig. 9 Correspondingly, the exhaust port 74 is connected to a mounting plate 78 through a resilient member 79. In this embodiment, the resilient member 79 is a spring. A brush 77 is provided on the side of the mounting plate 78 facing the filter ball frame. The brush 77 abuts against the filter screen 76, so that the surface of the filter screen 76 can be continuously brushed during the rotation of the filter ball frame to prevent the mesh of the filter screen 76 from being clogged with too much dust. The filter ball frame of this embodiment can be made of plastic, which is light and easy to rotate. In other embodiments, the filter ball frame can also be made of metal, which has higher strength and better durability. The actual situation can be adjusted according to the specific material of the foam.

[0042] The implementation principle of this embodiment is: the foam is stably pressed down by the pressing belt 2, which effectively prevents the foam from "bouncing" or shaking during the die-cutting process, thereby improving the die-cutting accuracy and quality. At the same time, the dust collection component 7 can clean up the debris generated during the die-cutting process in time, keep the working environment clean, and improve the reliability and life of the equipment. In addition, the design of the power roller 6 can reduce the resistance of the foam during the transportation process and improve the transportation and production efficiency.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
