Description

Technical Field

[0001] The invention relates to the technical field of rubber material head heating, in particular to a tread rubber material head heating device. Background Art

[0002] Due to the formula of the tread rubber itself, it is necessary to heat the head and tail of the material before bonding to achieve a better bonding effect, improve bonding efficiency and ensure tire quality.

[0003] The patent with the patent announcement number CN210174221U relates to the field of rubber material head heating technology, including: a tread conveying template for conveying tread rubber; a position collector for collecting the position information of the tread rubber material head; a heating transmission mechanism arranged on one side of the tread conveying template; a heating mechanism arranged on the heating transmission mechanism; and a controller. When the tread rubber material head heating device in the utility model is used, the tread conveying template conveys the tread rubber. When the tread rubber material head reaches the position collector, the position collector generates a position signal. The controller controls the heating transmission mechanism and the tread conveying template to operate synchronously at a preset time interval according to the position signal, and controls the heating mechanism to start heating. It can be seen that when the tread rubber material head is heated by the tread rubber material head heating device of the patent, it is not necessary to stop the conveying of the tread rubber, thereby improving the production efficiency of the tread rubber.

[0004] The above-mentioned patented tread rubber material head heating device does not need to stop the tread rubber material conveying when heating the tread rubber material head, thereby improving the production efficiency of the tread rubber material. However, when heating the rubber material, the internal heat is easily lost quickly due to the unsealed feed trough, resulting in incomplete heating of the rubber material. Summary of the invention

The rotation of the gear shaft will drive the blade to rotate, and the rotation of the blade will chop the rubber inside the feed trough. Cutting the rubber into smaller pieces helps to evenly distribute the rubber components, so that heat can be more easily transferred to each small piece of rubber, which helps to achieve more uniform heating, avoid uneven heating or excessive temperature gradient, and ensure that the rubber reaches a uniform temperature during the entire heating process.

[0008] Preferably, a soft rope is fixedly installed on the side of the No. 1 baffle plate close to the gear shaft, and the end of the soft rope away from the No. 1 baffle plate is fixedly installed on the circumferential surface of the gear shaft. The opening and closing of the No. 1 baffle plate and the No. 2 baffle plate can be controlled by the degree of pulling of the soft rope by the gear shaft, and the rack is meshed with the gear shaft.

[0011] Preferably, a No. 1 spring is provided between the sliding pin and the No. 2 fixed block, and the No. 1 spring is provided to push the sliding pin into the inner wall of the No. 2 square groove to limit the flip cover. A No. 2 spring is provided between the latch and the discharge frame, and the No. 2 spring is provided to drive the latch back to its original position. A No. 1 square groove is provided on the upper surface of the fixed plate, and the latch contacts the inner wall of the No. 1 square groove.

The sliding of the sliding plate will pull the square plate to move upward, and the upward movement of the square plate will be driven by the No. 5 torsion spring to rotate, so that the square plate will lean against the inner wall of the material discharge frame, so that the rubber material accumulated on the surface of the square plate will slide into the inside of the material discharge frame to avoid the rubber material piling up and causing incomplete heating of the center position of the rubber material.

[0013] Preferably, the scraper device also includes a push plate, a No. 1 block and a No. 2 block. The push plate is slidably mounted on the top of the square plate, the No. 2 block is fixedly mounted on the inner wall of the discharge frame, and the No. 1 block is fixedly mounted on the side of the push plate close to the No. 2 block. The No. 1 block will push the push plate to slide away from the square plate, scrape off the remaining rubber on the surface of the square plate, and make the rubber on the inner wall surface of the discharge frame to enhance the melting of the rubber and make the rubber melt more completely.

[0015] The present invention provides a tread rubber material head heating device, which has the following beneficial effects:

[0016] (1) The residual heat emitted by the heating frame is used to preheat the rubber material so that its surface is dried. When there is enough rubber material in the feed trough, the cover is closed to seal the feed trough to prevent the heat inside the heating frame from being dissipated. When the feed trough is not sealed, part of the heat may be carried away by the air, resulting in reduced heating efficiency. This will not only prolong the heating time, but may also cause uneven heating of the rubber material, affecting the performance and quality of the rubber material. The rotation of the gear shaft will drive the blade to rotate, and the rotation of the blade will chop the rubber material inside the feed trough. Cutting the rubber material into smaller pieces helps to evenly distribute the rubber material components, so that heat can be more easily transferred to each small piece of rubber, which helps to achieve more uniform heating, avoid uneven heating or excessive temperature gradients, and ensure that the rubber material reaches a uniform temperature throughout the heating process.

[0017] (2) When the No. 2 baffle rotates, it will drive the pressure rod to rotate. When the pressure rod rotates, it will push the pin to contact the inner wall of the No. 1 square groove. The fixed plate will limit the discharge frame so that the discharge frame will not move when the rubber enters the discharge frame, avoiding the rubber from not entering the discharge frame. If the rubber does not enter the discharge frame, the rubber that does not enter the discharge frame may fall on the surface of the conveying device. After heating, the rubber may continue to adhere to the surface of the conveying device. When the heater is turned off, the rubber attached to the surface of the conveying device will harden. The hardened rubber may affect the transportation of the conveying device. The sliding pin will be inserted into the inner wall of the No. 2 square groove to limit the flap, so that the staff will not open the flap at will when pouring out the melted rubber, avoiding the rubber from flowing out from the flap when pouring the rubber into the mold, so that the rubber does not completely enter the mold, resulting in incomplete molding of the rubber.

[0018] (3) The sliding of the sliding plate will pull the square plate upward, and the square plate will be driven by the No. 5 torsion spring to rotate. The square plate will lean against the inner wall of the discharge frame, so that the rubber accumulated on the surface of the square plate will slide into the inside of the discharge frame to avoid the rubber piling up and incomplete heating of the center of the rubber. It will also prevent the rubber from entering the mold when the rubber is poured into the mold and affecting the molding of the rubber. The No. 1 block will push the scraper to slide away from the square plate, scraping off the remaining rubber on the surface of the square plate, so that the rubber is on the inner wall of the discharge frame to enhance the melting of the rubber and make the rubber melt more completely.
