Description

Technical Field

[0001] The utility model relates to the technical field of rubber stamping equipment, in particular to a novel stamping device for rubber processing. Background Art

[0002] In industrial manufacturing, rubber products are widely used across various industries due to their excellent elasticity and wear resistance. To enhance the product's functionality or aesthetics, stamping is often performed on the surface of rubber products to create specific patterns. These patterns not only enhance the product's anti-slip properties but also serve as decorative elements to enhance the product's appearance.

[0003] In the prior art, stamping devices typically consist of a base plate with a specific pattern and a corresponding indenter. During the stamping process, the rubber material is placed on the base plate, and then the indenter applies pressure to form the desired pattern on the rubber material's surface. However, due to the certain viscosity and elasticity of rubber materials, the stamped rubber product often adheres tightly to the base plate. Workers must use tools to carefully lift one side of the rubber product and then pull it to remove it from the base plate. This process is not only time-consuming and labor-intensive, reducing production efficiency, but also increases the workload of operators, making it less practical. Therefore, we propose a new stamping device for rubber processing to address this problem. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0027] The present application provides a novel stamping device for rubber processing, which is mainly used to solve the problem in the prior art that, due to the certain viscosity and elasticity of rubber materials, rubber products after stamping tend to adhere tightly to the base plate, and workers have to use tools to carefully lift one side of the rubber product and then pull the rubber product to remove it from the base plate. This process is not only time-consuming and labor-intensive, reducing production efficiency, but also increases the workload of operators and has low practicality. The following technical solutions are provided, which will be combined with Figure 1-Figure 5 Give detailed instructions:

[0028] A new stamping device for rubber processing, comprising:

[0029] The mounting box 1 has support rods 2 fixed at the four corners of its top surface, a mounting plate 3 fixed on the top of the support rods 2, and a hydraulic cylinder 4 installed in the middle of the top of the mounting plate 3;

[0030] The movable plate 5 is arranged between the mounting box 1 and the mounting plate 3. The piston end of the hydraulic cylinder 4 passes through the mounting plate 3 and is connected to the top of the movable plate 5. Rectangular channels 501 are constructed on both sides of the movable plate 5.

[0031] The stamped bottom plate 6 is fixedly embedded in the middle of the top of the installation box 1. The surface of the stamped bottom plate 6 is provided with four circular holes 601 arranged in a rectangular shape.

[0032] The stamped top plate 7 is arranged at the bottom of the movable plate 5. Extension plates 701 are fixed on both sides of the top of the stamped top plate 7. The extension plates 701 slide through the rectangular channel 501. The bottom surface of the stamped top plate 7 is evenly distributed with protrusions or grooves for printing patterns.

[0033] The ejection mechanism 8 is arranged in the circular hole 601 and is used to lift the rubber product;

[0034] The locking mechanism 9 is provided on both sides of the top of the mounting plate 3 , and is used for clamping and fixing the stamping top plate 7 .

[0035] Workflow Description:

[0036] The first step is to place the rubber material on the stamping base plate 6 and ensure that it is positioned correctly;

[0037] In the second step, the hydraulic cylinder 4 is started to move the movable plate 5 downward, thereby driving the stamping top plate 7 to contact the rubber material. The protrusions or grooves of the stamping top plate 7 print the required patterns on the surface of the rubber material. After the stamping is completed, the hydraulic cylinder 4 retracts, the movable plate 5 moves upward, and the stamping top plate 7 leaves the rubber material.

[0038] The third step is to start the ejection mechanism 8 to lift the rubber product from the stamping base plate 6, so that the demoulding operation of the rubber product can be completed quickly;

[0039] When the stamping top plate 7 needs to be replaced, the locking mechanism 9 can be operated to replace the stamping top plate 7, so that the device can adapt to the printing of various patterns.

[0040] This new stamping device for rubber processing mainly relies on the hydraulic cylinder 4 to provide power, and drives the stamping top plate 7 to stamp the rubber material through the movable plate 5. The protrusions or grooves of the stamping top plate 7 print the required patterns on the surface of the rubber material. After the stamping is completed, the ejection mechanism 8 lifts the rubber product from the stamping bottom plate 6. On the one hand, it avoids the process of using tools to lift the rubber product, reduces the risk of damage to the rubber product, and reduces the time and labor intensity of manual operation. In addition, by setting the locking mechanism 9, the staff can quickly replace the stamping top plate 7 according to different production needs, so that the device can adapt to the printing of various patterns and can be used for processing various types of rubber products, thereby improving the scope of use and flexibility of the equipment.

[0041] like Figure 3As shown, in some embodiments, the ejection mechanism 8 includes a bar electromagnet 801 installed on both sides of the interior of the installation box 1, and the top two sides of the bar electromagnet 801 are connected to the return spring 802, the inside of the circular hole 601 is fixedly embedded with a guide tube 803, the inside of the guide tube 803 is slidably inserted with a push rod 804, the bottom of the push rod 804 is fixed with a sleeve 805, the end of the return spring 802 away from the bar electromagnet 801 is connected to the inner top wall of the sleeve 805, and the bottom of the sleeve 805 is fixed with an iron ring 806 More specifically, the working principle of the ejection mechanism 8 is as follows: during the stamping process, the bar electromagnet 801 is energized and activated. The energized bar electromagnet 801 attracts the iron ring 806, causing the ejector rod 804 to move downward along the guide tube 803. At this time, the upper end of the ejector rod 804 is parallel to the stamping bottom rod. When the rubber product needs to be lifted, the bar electromagnet 801 is de-energized, and the reset spring 802 releases energy, pushing the sleeve 805 and the ejector rod 804 to move upward, lifting the rubber product, thereby making it easier for the staff to remove the rubber product.

[0042] like Figure 4 As shown, in some embodiments, the locking mechanism 9 includes a hinged rod 901 hinged at intervals on the side of the movable plate 5, the free end of the hinged rod 901 is connected to the end plate 902, the surface of the hinged rod 901 is slidably sleeved with an extrusion rod 903, a clamping spring 904 is connected between the end plate 902 and the extrusion rod 903, the clamping spring 904 is sleeved on the surface of the hinged rod 901, the side of the extension plate 701 is constructed with a U-shaped notch 7011, and the hinged rod 901 is slidably embedded in the U-shaped notch 7011. More specifically, when the stamped top plate 7 needs to be fixed, the extension plate 701 can be first passed through the rectangular channel 501, and then the hinged rod 901 can be manually operated to surround it. The connection point with the movable plate 5 rotates. At the same time, it is necessary to press the extrusion rod 903 so that the clamping spring 904 is in a compressed state. When the extrusion rod 903 is close to the extension plate 701, the extrusion rod 903 is released. Under the action of the clamping spring 904, the extrusion rod 903 is embedded in the U-shaped notch 7011 of the extension plate 701, thereby clamping and fixing the extension plate 701 to ensure that the stamping top plate 7 remains stable during operation. When the stamping top plate 7 needs to be released, the hinged rod 901 is operated in reverse to make it rotate, and the extrusion rod 903 is disengaged from the U-shaped notch 7011, so that the clamping of the stamping top plate 7 can be released, making it convenient for the staff to replace the stamping top plate 7.

[0043] like Figure 4As shown, in some embodiments, sleeves 502 are fixedly embedded at the four corners of the movable plate 5, and the sleeves 502 are slidably sleeved on the surface of the support rod 2. More specifically, the cooperation between the sleeves 502 and the support rod 2 provides a stable guide for the movable plate 5, ensuring that it remains stable during the up and down movement, avoiding tilting or offset, thereby ensuring the accuracy and consistency of the stamping. At the same time, the tube acts as a sliding element, reducing the direct friction between the movable plate 5 and the support rod 2, reducing wear, and extending the service life of the equipment.

[0044] like Figure 1 As shown, in some embodiments, a supporting plate 10 is fixed to the bottom surface of the installation box 1, and mounting holes are opened at the four corners of the supporting plate 10. More specifically, the supporting plate 10 is fixed to the workbench through the mounting holes, providing a solid foundation for the installation box 1, ensuring the stability of the equipment during operation, and reducing displacement or tilting caused by vibration or external force.
