Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tires, and in particular to a tread pattern extrusion molding device. Background Technology

[0002] In tire manufacturing, tread extrusion is a crucial step. Tread compound is extruded through an extruder head into continuous tread strips with a specific pattern, followed by cooling, length cutting, and other subsequent processing.

[0003] Existing tread pattern extrusion molding devices, such as the tread extruder for manufacturing pneumatic inner tubes disclosed in utility model patent application number 202323581721.X, mainly include an extruder body. A fixed plate is fixedly connected to the front side of the extruder body. An adjustment groove is opened on the top of the fixed plate. An adjustment block is slidably connected to the inner wall of the adjustment groove. In use, the raw material is added into the extruder body through the feed hopper. Then, the extruder body is started, so that the extruder body can heat and soften the raw material, and then convey and extrude it.

[0004] However, most existing molding devices can only extrude flat tire surfaces, making it difficult to extrude treaded tire surfaces. Moreover, they require a long cooling time after extrusion, and uneven cooling of the upper and lower surfaces of the tire surface can easily affect the quality. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tire tread pattern extrusion molding device that can not only directly press patterns onto the extruded tire surface, improving work efficiency, but also simultaneously cool the upper and lower sides of the tire surface, ensuring uniform cooling and guaranteeing the quality of the tire surface.

[0006] This utility model discloses a tire tread pattern extrusion molding device, including a heating mechanism; it also includes an extrusion mechanism, a shaping mechanism, a water cooling mechanism, and a spraying mechanism. The extrusion mechanism is installed on the heating mechanism and extrudes the rubber material; the shaping mechanism is installed on the heating mechanism and extrudes the pattern on the tire surface; the water cooling mechanism is installed on the extrusion mechanism and cools the lower surface of the tire surface; and the spraying mechanism is installed on the water cooling mechanism and cools the upper surface of the tire surface. The operator adds the rubber material into the heating mechanism for heating, the extrusion mechanism extrudes the rubber material, the shaping mechanism positions the tire surface and presses out the pattern, and the water cooling mechanism and the spraying mechanism work together to cool the upper and lower sides of the tire surface respectively, ensuring the cooling effect of the tire surface.

[0007] Preferably, the heating mechanism includes a support frame, an extrusion cylinder, a heater, a feeding hopper, and a sealing cover. The bottom end of the support frame is connected to the ground, the extrusion cylinder is mounted on the support frame, and the inside of the extrusion cylinder is provided with a cavity. The heater is mounted on the extrusion cylinder, the bottom end of the feeding hopper is connected to the top end of the extrusion cylinder, and the sealing cover is rotatably mounted on the feeding hopper. The operator opens the sealing cover and feeds the rubber material into the cavity of the extrusion cylinder through the feeding hopper, and the heater heats the rubber material.

[0008] Preferably, the extrusion mechanism includes a motor, a reducer, a drive shaft, and helical blades. The motor is mounted on the extrusion cylinder, and the output end of the motor is connected to the input end of the reducer. The output end of the reducer is connected to the input end of the drive shaft, and the helical blades are mounted on the drive shaft. When the motor is started, the motor drives the drive shaft to rotate through the reducer, and the drive shaft drives the helical blades to rotate to extrude the rubber material.

[0009] Preferably, the shaping mechanism includes a shaping table, two sets of cylinders, a connecting frame, two sets of insert plates, a shaping plate, a thin sheet metal, and two sets of pattern rollers. The shaping table is mounted on a support frame and communicates with the inside of the discharge port of the extrusion cylinder. Two sets of positioning grooves are opened on the shaping table. Both sets of cylinders are mounted on the shaping table. The top of the connecting frame is connected to the bottom of the two sets of cylinders. The top of the two sets of insert plates is connected to the bottom of the connecting frame, and the two sets of insert plates are respectively inserted into the two sets of positioning grooves. The shaping plate is mounted on the connecting frame. The thin sheet metal is connected and installed between the shaping plate and the shaping table. Both sets of pattern rollers are rotatably mounted on the connecting frame. Activating the two sets of cylinders pushes the connecting frame down, which facilitates the adjustment of the extruded tread thickness. The two sets of insert plates move in the positioning grooves to ensure the stability of the connecting frame. The thin sheet metal is used to prevent the rubber material from affecting the movement of the cylinders. The shaping plate works with the shaping table to shape the rubber material. The discharged tread is rolled into patterns by the two sets of pattern rollers.

[0010] Preferably, the raised areas on the surface of the pattern roller are made of polytetrafluoroethylene (PTFE). PTFE has extremely low surface energy, which can prevent rubber from adhering to it and affecting the tread forming effect. It can also work in high-temperature environments for a long time, meeting the temperature requirements of the tread, and it hardly reacts with the rubber.

[0011] Preferably, the water-cooling mechanism includes a protective box, water-cooled rollers, a water distributor, a water supply pipe, and a first valve. The protective box is mounted on a support frame and communicates with the interior of the shaping table. Multiple sets of water-cooled rollers are rotatably mounted on the protective box. The water distributor is mounted on the protective box and communicates with the interior of the multiple sets of water-cooled rollers. The water supply pipe is communicated with the interior of the water distributor. The first valve is mounted on the water supply pipe. The tire tread is pushed onto the multiple sets of water-cooled rollers. The water supply pipe is connected to a water source. The first valve is opened, and cooling water is delivered to the water distributor. The water distributor delivers the cooling water to the multiple sets of water-cooled rollers, thereby cooling the lower surface of the tire tread.

[0012] Preferably, the spraying mechanism includes a connecting pipe, a second valve, and multiple sets of spray heads. The connecting pipe is connected to the inside of the water supply pipe, the second valve is installed on the connecting pipe, and the multiple sets of spray heads are all installed on the protective box and connected to the inside of the protective box. When the second valve is opened, cooling water is transported to the multiple sets of spray heads through the connecting pipe.
