However, when traditional silicone parts are prepared by die-cutting, continuous die-cutting cannot be performed. Each time of die-cutting requires a pause to remove the cut silicone parts before the next die-cutting operation can be carried out, resulting in low production efficiency of silicone parts. This problem urgently needs to be solved. Summary of the Invention

[0006] By adopting the above technical solutions, when die-cutting operations on silicone parts are required, the conveying device conveys the silicone part coil. During the conveying process of the silicone part coil, the die-cutting device performs continuous die-cutting operations on the silicone part coil, and then the blanking device receives and blanks the silicone parts after die-cutting operations. During the die-cutting process of the silicone parts, there is no need to pause to remove the cut silicone parts and then perform the next die-cutting operation. The die-cutting operations are continuous, which is beneficial to improving the production efficiency of silicone parts.
[0007] Preferably, the conveying device includes a conveying frame, a support plate, a discharging roller, and a winding roller. The discharging roller and the winding roller are respectively rotatably connected to the head and tail ends of the conveying frame. The silicone part coil is conveyed out from the discharging roller and wound on the winding roller. The support plate is fixedly arranged on the conveying frame and is located at the position between the discharging roller and the winding roller. The original silicone part material conveyed out is slidably connected to the plate surface of the support plate.

The discharge roller and the receiving roller are rotatably connected to the head and tail ends of the conveying frame respectively, and the silicone coil is conveyed from the discharge roller and then rolled up on the receiving roller to realize the continuous conveyance of the silicone coil. At the same time, the support plate supports the silicone coil being conveyed, so that the die-cutting device can perform die-cutting operations on the silicone coil.
[0009] Preferably, the die-cutting device includes a support frame, a die-cutting roller and a die-cutting knife. The support frame is fixedly arranged on the conveying frame, and the support frame is located on the conveying path of the silicone member. The die-cutting roller is rotatably connected to the support frame.

As the die-cutting roller rotates, the die-cutting knives perform die-cutting operations on the silicone member raw material that is slidably connected to the support plate.
[0010] By adopting the above technical solution, the support frame supports the die-cutting roller and the die-cutting knife. As the silicone coil is conveyed, a plurality of die-cutting knives rotate with the die-cutting roller to perform die-cutting operations on the silicone coil.

The loading component is arranged on one side of the die-cutting roller and is used to collect the silicone product pushed out by the pushing component.
[0016] By adopting the above technical solution, the die-cutting roller drives the silicone product pushed into the die-cutting knife frame to rotate. When the silicone product moves to a position close to the loading component, the pushing component pushes out the silicone product in the die-cutting knife frame, and the pushed-out silicone product falls into the loading component for collection. The collection operation is convenient and fast, without manual operation.
[0017] Preferably, the pushing component includes a driving part and a pushing plate. The driving part is arranged in the die-cutting knife frame and is used to drive the pushing plate to reciprocate along the depth direction of the die-cutting knife frame.
[0018] By adopting the above technical solution, when the silicone product is close to the loading component, the driving part drives the pushing plate to push out the silicone product in the die-cutting knife frame and fall into the loading component for collection, thus completing the blanking operation of the silicone product.

[0023] Preferably, protective plates are vertically and fixedly arranged on opposite sides of the die-cutting roller of the conveying frame.
[0024] By adopting the above technical solution, the protective plate can isolate the die-cutting roller and the die-cutting knife performing the die-cutting operation, thereby protecting the workers from injury during the die-cutting process, which is conducive to improving safety.
[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1.

[0032] The following is combined with Figures 1-3 This application is described in further detail.
[0033] The present application embodiment discloses a silicone die cutting system, referring to Figure 1 , including a conveying device 1, a die-cutting device 2 and a feeding device 3. The conveying device 1 conveys the silicone coil, the die-cutting device 2 is arranged on the conveying path of the silicone coil to perform continuous die-cutting operations on the silicone coil, and the feeding device 3 is arranged on one side of the die-cutting device 2 to receive and feed the silicone after the die-cutting operation. During the die-cutting production process of the silicone, there is no need to pause to remove the cut silicone before the next die-cutting operation. The die-cutting operation is continuous, which is conducive to improving the production efficiency of silicone.
[0034] Reference Figure 1 The silicone die-cutting system also includes a control device 6 for conveying and die-cutting the silicone coil. The control device 6 includes a PLC controller and a touch screen. The PLC controller is connected to the touch screen by telecommunications. The PLC controller is used to receive and process signals and control the actions of each device. The touch screen is used to display the system status and input control instructions, thereby realizing the control of conveying, die-cutting and receiving actions, with a high degree of automation.
[0035] Reference Figure 1 The conveying device 1 includes a conveying frame 11, a support plate 12, a discharge roller 13, and a receiving roller 14. The conveying frame 11 supports the discharge roller 13, the receiving roller 14, and the support plate 12. The discharge roller 13 and the receiving roller 14 are respectively connected to the front and rear ends of the conveying frame 11. The rotation of the discharge roller 13 and the receiving roller 14 is driven by a driving motor, which will not be described in detail here. The silicone coil is wound around the discharge roller 13. The silicone coil is transported from the discharge roller 13 and then rolled up on the receiving roller 14. In this embodiment, the silicone coil is transported in a horizontal state. The support plate 12 is horizontally fixedly arranged on the conveying frame 11, and the support plate 12 is located between the discharge roller 13 and the receiving roller 14. The silicone raw material transported is abutted and slid on the plate surface of the support plate 12. The support plate 12 supports the silicone coil being transported, so that the die-cutting device 2 can perform die-cutting operations on the silicone coil.
[0036] Reference Figure 1, the die-cutting device 2 includes a support frame 21, a die-cutting roller 22 and a die-cutting knife 23. The support frame 21 is fixedly arranged on the conveying frame 11 to support the die-cutting roller 22 and the die-cutting knife 23, and the support frame 21 is located above the conveying path of the silica gel part. The die-cutting roller 22 is rotatably connected to the support frame 21, and the rotation of the die-cutting roller 22 is also driven by a motor. The number of die-cutting knives 23 is set to several, and several die-cutting knives 23 are arranged on the roller surface of the die-cutting roller 22 in a rectangular array. In this embodiment, the die-cutting knife 23 is arranged in a rectangular frame shape so that the cut silica gel part product is rectangular. The die-cutting knife 23 at the bottom of the die-cutting roller 22 abuts against the silica gel part, and several die-cutting knives 23 perform die-cutting operations on the silica gel raw material slidably connected to the support plate 12 as the die-cutting roller 22 rotates.
[0037] Refer to Figure 1 and Figure 2 , a blanking component 4 is arranged on the support plate 12. After the die-cutting operation is completed, the blanking component 4 pushes the die-cut silica gel part product into the frame of the die-cutting knife 23 to realize the separation of the silica gel part product from the silica gel raw material. The silica gel part product is embedded in the frame of the die-cutting knife 23 so that the silica gel part product moves as the die-cutting roller 22 rotates. Specifically, the blanking component 4 includes a blanking plate 41 and a blanking spring 42. At the same time, a receiving groove 5 for accommodating the blanking component 4 is opened at the position of the support plate 12 where the die-cutting operation is performed. The blanking spring 42 is vertically fixed in the receiving groove 5, and the blanking plate 41 is horizontally fixedly connected to the upper end of the blanking spring 42. When the blanking spring 42 is in a natural state, the blanking plate 41 extends upward out of the receiving groove 5. During the conveying process of the silica gel coil, the silica gel coil is tightened to press the blanking plate 41 into the receiving groove 5. At this time, the blanking spring 42 is in a compressed state. After the die-cutting operation is completed, the restoring force of the blanking spring 42 returning to the natural state pushes the die-cut silica gel part product into the frame of the die-cutting knife 23 through the blanking plate 41, thereby realizing the separation of the silica gel part product from the silica gel coil. The four sides of the silica gel part product abut against the inner wall of the frame of the die-cutting knife 23, so that the silica gel part product moves as the die-cutting roller 22 rotates.
[0038] Refer to Figure 1 and Figure 3 , the blanking device 3 includes a pushing component 31 and a loading component 32. When the die-cut silica gel part product moves to a position close to the loading component 32, the pushing component 31 is arranged on the die-cutting roller 22 to push the silica gel part product in the frame of the die-cutting knife 23 out, and the loading component 32 is arranged on one side of the die-cutting roller 22 to collect the silica gel part product pushed out by the pushing component 31 to realize the automatic blanking operation of the silica gel part product.
[0039] Refer to Figure 3, the material pushing assembly 31 includes a driving member 311 and a material pushing plate 312. The driving member 311 is arranged inside the frame of the die-cutting blade 23 and is used to drive the material pushing plate 312 to reciprocate along the depth direction of the frame of the die-cutting blade 23. In this embodiment, the driving member 311 is set as a small driving cylinder. The driving cylinder is fixed inside the die-cutting roller 22, and the piston rod of the driving cylinder penetrates into the frame of the die-cutting blade 23 movably. The material pushing plate 312 is fixedly connected to the piston rod of the driving cylinder. The contraction of the piston rod of the driving cylinder drives the material pushing plate 312 to move towards the inside of the frame of the die-cutting blade 23 to avoid the position of the silicone part product entering the frame of the die-cutting blade 23. The stretching of the piston rod of the driving cylinder drives the material pushing plate 312 to move towards the outside of the frame of the die-cutting blade 23 to push the silicone part out of the frame of the die-cutting blade 23.
[0040] Referring to Figure 1 , the loading assembly 32 includes a loading frame 321 and a connecting rod 322. The loading frame 321 is located on one side of the die-cutting roller 22. One end of the connecting rod 322 is fixedly connected to the conveying frame 11, and the other end of the connecting rod 322 is fixedly connected to the loading frame 321. When the silicone part product is pushed out of the frame of the die-cutting blade 23, the loading frame 321 is located on one side of the die-cutting roller 22 to receive and collect the silicone part product.
[0041] Referring to Figure 1 , protective plates 7 are vertically and fixedly arranged on opposite sides of the die-cutting roller 22 of the conveying frame 11 to isolate the die-cutting roller 22 and the die-cutting blade 23 during die-cutting operations, protecting the staff from harm during die-cutting and being beneficial to improving safety.
[0042] The implementation principle of a silicone part die-cutting system according to an embodiment of the present application is as follows: When die-cutting operations need to be performed on silicone parts, the silicone part coil is conveyed by the rotation of the discharging roller 13 and the material collecting roller 14. The support plate 12 supports the conveyed silicone part coil. During the conveying of the silicone part coil, the rotating die-cutting roller 22 drives the die-cutting blade 23 to perform die-cutting operations. Then, the ejecting spring 42 ejects the die-cut silicone part product into the frame of the die-cutting blade 23 through the ejecting plate 41, and the rotating die-cutting roller 22 drives the silicone part product to move. When the silicone part product moves close to the loading frame 321, the driving cylinder pushes the silicone part product out through the material pushing plate 312 and it falls into the loading frame 321 for collection. During the die-cutting of silicone parts, there is no need to pause to remove the cut silicone parts and then perform the next die-cutting operation. The die-cutting operations are continuous, which is beneficial to improving the production efficiency of silicone parts.
[0043] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
