Description

Technical Field

[0001] This utility model relates to the field of tire processing technology, specifically to a preforming device for vulcanizing bladders of thin all-steel radial tires. Background Technology

[0002] In the production process of all-steel radial tires, vulcanization is a crucial step. The vulcanizing bladder, as the core internal mold for tire vulcanization, is filled with a high-pressure hot medium during the vulcanization process. This medium applies pressure and heat to the tire blank from the inside, causing it to solidify and mature. The performance and condition of the vulcanizing bladder directly affect the final tire quality, production efficiency, and the bladder's own lifespan. Before installing the vulcanizing bladder onto the vulcanizing machine, it typically needs to be expanded from its original contracted state by a preforming device and shaped into a specific shape that matches the inner contour of the tire blank. This process is called "preforming." A stable and precise preforming process is essential to ensure that the bladder can be smoothly and without damage inserted into the tire blank and accurately positioned on the central mechanism of the vulcanizing machine. Currently, preforming devices transport raw materials to the processing area through a feed pipe for preforming. During the material transport, a built-in agitator mixes the materials. However, most agitators in preforming devices are fixed with multiple sets of bolts, increasing subsequent operating procedures and complicating disassembly and assembly, thus reducing the efficiency of the preforming device. Utility Model Content

[0003] The purpose of this invention is to provide a preforming device for the vulcanizing bladder of thin all-steel radial tires, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pre-forming device for a thin all-steel radial tire vulcanizing bladder, comprising a forming machine, a machine door on the front of the forming machine, a mixing tank fixedly connected to one side of the forming machine, a feed pipe connected to the outside of the mixing tank, an mounting plate fixedly connected to the top of the mixing tank, an adjusting structure inside the mixing tank, a second motor clamped inside the mixing tank, a stirring column at the bottom of the second motor, a clamping structure inside the mounting plate connected to the second motor, bolts inside the mounting plate connected to the clamping structure, the clamping structure comprising a moving plate, a column, and a clamping plate, a spring on one side of the moving plate, and a connecting plate rotatably connected to the outside of the column.

[0005] As a further preferred embodiment of this technical solution, an indicator light is fixedly connected to the top of the molding machine, and a controller is fixedly connected to the front of the molding machine.

[0006] As a further preferred embodiment of this technical solution, the movable plate is slidably connected within the mounting plate, the clamping plate is slidably connected within the mounting plate, and the clamping plate is engaged with the motor.

[0007] As a further preferred embodiment of this technical solution, the movable plate is connected to the clamping plate by a spring, the bolt is connected to the clamping plate, the connecting plate is connected to the clamping plate, and the column is fixedly connected inside the mounting plate.

[0008] As a further preferred embodiment of this technical solution, the adjustment structure includes a rotating shaft, which is rotatably connected inside the mixing tank, and a sealing disc is connected to the outside of the rotating shaft.

[0009] As a further preferred embodiment of this technical solution, the sealing disc overlaps inside the mixing tank, and one end of the rotating shaft is connected to a motor, which is fixedly connected to the outside of the mixing tank.

[0010] As a further preferred embodiment of this technical solution, the motor is externally fixedly connected to a limiting plate, which is snapped into the mixing tank.

[0011] This utility model provides a preforming device for thin all-steel radial tire vulcanizing bladders, which has the following beneficial effects:

[0012] (1) This utility model sets up a mixing tank, a mounting plate, and a second motor with a snap-fit ​​structure to apply a pushing force to the moving plate. The moving plate will slide in the mounting plate. Since the moving plate is connected to the snap-fit ​​plate through the connecting plate, the connecting plate will rotate on the surface of the column. The snap-fit ​​plate and the moving plate will move relative to each other. When moving, the spring will deform. Subsequently, the second motor is snapped into the mixing tank. The limiting plate on the surface of the second motor will snap into the mixing tank. When the moving plate is released, the snap-fit ​​plate will be reset by the spring and snap-fit ​​into the second motor. The mounting plate is then fixed to the snap-fit ​​plate with bolts. This preforming device enables the second motor and the mixing column to be quickly assembled with the mixing tank through the cooperation between the spring, the snap-fit ​​plate and the bolts. It is convenient to disassemble and assemble the mixing column and can repair or replace the surface of the mixing column in a timely manner, thereby improving the working efficiency of the preforming device.

[0013] (2) By setting an adjustment structure, the stirring column is driven by motor 2 to rotate, and the stirring column will fully stir the raw materials inside. Then, the sealing plate is driven by motor 1 to rotate around the rotating shaft. When the sealing plate is unfolded, the raw materials inside will enter the processing area. The feeding amount of raw materials can be controlled to avoid unevenly mixed raw materials from entering the processing area, thereby improving the product quality. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown, in this embodiment, the preforming device for the thin all-steel radial tire vulcanizing bladder includes a molding machine 1. The front of the molding machine 1 is provided with a machine door 2. A mixing tank 3 is fixedly connected to one side of the molding machine 1. A feed pipe 5 is connected to the outside of the mixing tank 3. An installation plate 7 is fixedly connected to the top of the mixing tank 3. An adjustment structure 8 is provided inside the mixing tank 3. A second motor 10 is clamped inside the mixing tank 3. A stirring column 11 is provided at the bottom of the second motor 10. A clamping structure 9 is provided inside the installation plate 7. The clamping structure 9 is connected to the second motor 10. A bolt 12 is provided inside the installation plate 7. The bolt 12 is connected to the clamping structure 9. The clamping structure 9 includes a moving plate 901, a column 902 and a clamping plate 905. A spring 904 is provided on one side of the moving plate 901. A connecting plate 903 is rotatably connected to the outside of the column 902.

[0021] like Figure 1 and Figure 3 As shown, an indicator light 6 is fixedly connected to the top of the molding machine 1, a controller 4 is fixedly connected to the front of the molding machine 1, a moving plate 901 is slidably connected to the mounting plate 7, a clamping plate 905 is slidably connected to the mounting plate 7, the clamping plate 905 is clamped to the motor 10, the moving plate 901 is connected to the clamping plate 905 by a spring 904, a bolt 12 is connected to the clamping plate 905, a connecting plate 903 is connected to the clamping plate 905, and a column 902 is fixedly connected to the mounting plate 7.

[0022] By setting spring 904, a pushing force is applied to the movable plate 901, which will slide within the mounting plate 7. Since the movable plate 901 is connected to the clamping plate 905 through the connecting plate 903, the clamping plate 905 and the movable plate 901 will move relative to each other. During the movement, the spring 904 will deform, so that the spring 904 provides a certain support for the movement of the movable plate 901 and the clamping plate 905, and prevents the movable plate 901 and the clamping plate 905 from jamming during the movement.

[0023] like Figure 2 and Figure 4 As shown, the adjustment structure 8 includes a rotating shaft 801, which is rotatably connected inside the mixing tank 3. A sealing disc 802 is connected to the outside of the rotating shaft 801, and the sealing disc 802 overlaps inside the mixing tank 3. One end of the rotating shaft 801 is connected to a motor 803, which is fixedly connected to the outside of the mixing tank 3. A limiting plate 13 is fixedly connected to the outside of the motor 10, and the limiting plate 13 is snapped into the mixing tank 3.

[0024] By setting the limiting plate 13, the second motor 10 is snapped into the mixing tank 3. The limiting plate 13 on the surface of the second motor 10 will snap into the mixing tank 3, thereby positioning the second motor 10 and preventing the second motor 10 from colliding with the clamping plate 905 when it is fixed.

[0025] This utility model provides a preforming device for the vulcanizing bladder of thin all-steel radial tires, and its specific working principle is as follows:

[0026] First, a pushing force is applied to the movable plate 901, which will slide within the mounting plate 7. Since the movable plate 901 is connected to the clamping plate 905 through the connecting plate 903, the connecting plate 903 will rotate on the surface of the column 902, and the clamping plate 905 and the movable plate 901 will move relative to each other. During the movement, the spring 904 will deform. Subsequently, the second motor 10 will be clamped into the mixing tank 3, and the limiting plate 13 on the surface of the second motor 10 will be clamped with the mixing tank 3. When the movable plate 901 is released, the clamping plate 905 will be reset by the spring 904, and the clamping plate 905 will be clamped with the second motor 10. The mounting plate 7 will then be fixed to the clamping plate 905 by bolts 12.

[0027] When the preforming device is in production, the raw materials can be transported through the feed pipe 5. During the transport, the raw materials will pass through the mixing tank 3. The mixing column 11 will rotate due to the motor 2 10. The mixing column 11 will fully mix the raw materials inside. Subsequently, the sealing disc 802 will be rotated around the rotating shaft 801 by the motor 1 803. When the sealing disc 802 is unfolded, the raw materials inside will enter the processing area.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
