[0002] Rubber processing refers to the process of making rubber products with specific shapes, sizes and performance requirements through a series of physical and chemical reactions on rubber (including natural rubber and synthetic rubber). During the entire rubber processing process, the semi-finished products of each process need to be quality inspected and controlled to ensure that the performance and quality of the final product meet the requirements. In addition, with the advancement of science and technology and the development of technology, rubber processing technology is also constantly innovating and improving to meet people's increasing demand for the performance and quality of rubber products. Tires are one of the rubber products.

[0003] At present, in the tire production process, the semi-finished tire will first be affixed with an airtight layer and an intermediate glue during the molding process, and then the cord will be applied and the wire ring will be buckled. After repeating the steps of affixing the cord, the triangle glue will be affixed again and compacted with a pressure roller. Then the shoulder pad glue will be affixed and compacted with a hand roller and a rear roller. Finally, the sidewall glue will be affixed and compacted with a hand roller. The rear roller of the molding machine will be used to compact the upper triangle, shoulder pad and sidewall glue. However, some existing rubber moldings contain gas. If the internal gas cannot be effectively discharged, it will cause problems such as air pockets, voids and bubbles in the semi-finished tire, and then cause scars, openings and other diseases in the finished tire, seriously affecting the quality of the finished product, resulting in a decrease in the tire yield and affecting normal production efficiency.

[0018] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0019] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in Figure 1 A schematic structural diagram of a preferred embodiment of the type glue piercing device provided by the present invention; Figure 2 for Figure 1 The schematic diagram of the structural connection between the pressure roller and the pressure roller bracket is shown; Figure 3 for Figure 1 The schematic diagram of the motor and sprocket structure connection is shown. A type rubber piercing device includes a frame 1 and a cylinder 2. The bottom of the cylinder 2 is fixedly connected to a mounting plate 3. The top of the frame 1 is fixedly connected to a guide rail 4. The top of the guide rail 4 is fixedly connected to the bottom of the mounting plate 3. The piston rod of the cylinder 2 is fixedly connected to a lifting bearing 5. The lifting bearing 5 has a nylon roller 6 installed inside. The outer side of the nylon roller 6 has a steel sleeve 7 fixedly connected. The outer side of the nylon roller 6 has a nylon roller 8. The frame 1 has a support rod 9 installed inside.

[0020] In the specific implementation process, Figure 1 As shown, a transmission roller 10 is provided inside the frame 1 , support plates 11 are fixedly connected to both sides of the inner wall of the frame 1 , and a support frame 12 is fixedly connected to the top of the support plate 11 .

[0021] A needle roller 13 is provided inside the support frame 12 , a connecting bearing 14 is provided on the outside of the needle roller 13 , and a needle shaft 15 is provided on the outside of the needle roller 13 .

[0022] A needle sheath 16 is provided on the outside of the needle shaft 15 , and a puncture needle 17 is provided inside the needle sheath 16 .

[0023] It should be noted that: start the cylinder 2, and under the action of the cylinder 2, the lifting bearing 5 can be driven to move. When the lifting bearing 5 moves, the nylon roller 6 inside it can be driven to move. At the same time, the lifting bearing 5 can move inside the guide rail 4 during movement, so that the movement of the lifting bearing 5 can be kept stable. When the lifting bearing 5 moves to the specified position, the nylon roller 6 can be moved to the specified position. When the rubber is pierced by the needle 17, the nylon roller 6 is lowered, and then the rubber can be pressed to ensure that the rubber will not be torn by the needle 17 due to insufficient tension during the piercing process, so that the air inside the rubber can be discharged. At the same time, the needle roller 13 is made of seamless steel pipe, and grooves are turned at both ends to place the connecting bearings 14. At the same time, the needle 17 is made of spring steel. The length of the needle 17 is determined according to the thickness of the rubber to ensure that rubbers of different thicknesses can be pierced. The needle shaft 15 cooperates with the support frame 12, and the two ends are fixed by a closing nut.

[0024] refer to Figure 2 and Figure 3 As shown, a fixing frame 18 is fixedly connected to the top of the frame 1 , a rocker 19 is provided on the outside of the support rod 9 , and a pressure roller 20 is provided inside the rocker 19 .

[0025] A motor 21 is provided on one side of the inner wall of the frame 1 , and a sprocket 22 is fixedly connected to the output end of the motor 21 .

[0026] It should be noted that: when the motor 21 is started, the sprocket 22 can be driven to rotate under the action of the motor 21, and then the transmission roller 10 can be driven to rotate through the sprocket 22, so that the transmission roller 10 can convey the rubber. At the same time, the staff can adjust the angle of the rocker 19 through the support rod 9, and then adjust the position of the pressure roller 20, so that the pressure roller 20 can give the advancing rubber a smaller friction force, so that there is a backward pulling force during the piercing process of the rubber, so that the rubber will not be folded or stuck during the forward process.

[0027] The working principle of the adhesive piercing device provided by the utility model is as follows:

[0028] When the staff uses this device to process the semi-finished tire product, the rubber profile needs to be cooled in the water tank after coming out of the extruder before being punctured. According to the thickness of the rubber profile, the position of the pressure roller 20 is adjusted by the rocker 19. After the pressure roller 20 is adjusted to the specified position, the cylinder 2 is started. Under the action of the cylinder 2, the lifting bearing 5 and the nylon roller 6 are moved. When the nylon roller 6 moves to the specified position, the rubber profile enters this device and is located on the top of the transmission roller 10. Under the action of the pressure roller 20, the rubber profile can be pressed and then friction can be applied to it. The rubber profile enters the needle 17, and the needle roller 13 rotates. At the same time, the cylinder 2 is started again to lower the nylon roller 6 to position the rubber profile. Then, under the action of the needle 17, the rubber profile can be punctured. The punctured rubber profile discharges the internal gas through the air hole to ensure that the semi-finished product will not be emptied or bubbled during the molding process, thereby improving the production quality of the tire semi-finished product.
