Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire vulcanization, and particularly relates to a rapid and uniform heating device for a tire vulcanizer. Background Art
[0002] A vulcanizer is a machine for vulcanizing various rubber and plastic products, with functions such as timed mold clamping, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. In the process of tire production, first, the embryo of the tire is formed, and then the embryo is heated and vulcanized by a tire vulcanizer. During the vulcanization process, the outer surface pattern blocks of the tire are formed by a mold, and air is inflated and pressurized into the inner side of the tire to ensure that the outer side of the embryo can closely adhere to the mold.
[0003] Currently, in the use of a vulcanizer, the tire is placed inside a holding barrel. Inside the middle part, the inside of the tire is fixed by a fixing column, and the lid is used to seal the holding barrel. The outer part of the tire is heated and printed by a heating plate. This operation is convenient and fast. However, due to the different sizes of tires, the internal sizes of the tires are different. Since the diameter of the fixing column is a fixed size, it cannot meet tires of any size. If the tire cannot be fixed, when heating, the tire will be squeezed, and the printed pattern will shift, greatly increasing the production cost.
[0004] Therefore, for the improvement of the existing rapid and uniform heating device of a tire vulcanizer, it is particularly important to design a new rapid and uniform heating device for a tire vulcanizer to solve the above technical defects and improve the practicality of the overall rapid and uniform heating device of the tire vulcanizer. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a rapid and uniform heating device for a tire vulcanizer to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A rapid and uniform heating device for a tire vulcanizer includes a hanging frame. A connecting block is installed at the middle of the hanging frame.

[0010] As a preferred embodiment of the present utility model, a fixed column is installed at the top of the lead screw, a connecting piece is installed at the bottom end of the lead screw, and a support column is installed between the fixed column and the connecting piece.
[0011] As a preferred embodiment of the present utility model, the top of the second connecting rod is rotatably connected to the fixed column. A rotating seat is installed inside the clamping plate, and the second connecting rod is connected to the clamping plate through the rotating seat.

The output end of the telescopic cylinder extends into the inside of the linkage sleeve.
[0015] Compared with the prior art, the beneficial effects of the present utility model are:
[0016] In the present utility model, by placing the tire inside the fixed barrel and placing the inner ring of the tire outside the limiting frame, through the rotation of the lead screw, the threaded sleeve descends outside the lead screw, causing the first connecting rod and the second connecting rod to unfold, and enabling the clamping plate to tightly fit the inner wall of the tire, effectively preventing the tire from shifting during the vulcanization process. By starting the hanging bracket, the connecting block drives the lid to seal the top of the fixed barrel. By starting the telescopic cylinder, the output end of the telescopic cylinder pushes the sliding sleeve to move, thereby driving the connecting ear to move along with the sliding sleeve. At the same time, through the design of the clamping rod and the placement rack, the clamping rod contracts inward. Meanwhile, the heating plate wraps around the outside of the tire and moves along with the clamping rod to achieve uniform heating of the tire. Through the design of the linkage sleeve, the four groups of clamping rods move synchronously. At the same time, the suction pipe is connected to the suction fan to adsorb the harmful gases generated during the heating of the inside of the fixed barrel, preventing the toxic gases from spreading to the outside after the lid and the fixed barrel are disengaged.

Detailed Embodiment
[0023] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment:
[0025] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:
[0026] A rapid and uniform heating device for a tire vulcanizer, including a suspension bracket 1, a connecting block 2 is installed at the middle of the suspension bracket 1, a lid 3 is installed at the bottom of the connecting block 2, a fixed barrel 4 is installed below the lid 3, an air suction pipe 401 is installed outside the fixed barrel 4, and a clamping assembly 5 is installed inside the fixed barrel 4;
[0027] The clamping assembly 5 is used to fix the inner ring of tires with different size specifications.
[0028] Further, please refer to Figure 2 and Figure 3 , in this embodiment, the clamping assembly 5 includes a lead screw 501, a threaded sleeve 502, a connecting seat 503, a first connecting rod 504, a second connecting rod 505 and a clamping plate 506. The lead screw 501 is installed inside the fixed barrel 4, the threaded sleeve 502 is installed outside the lead screw 501, the connecting seat 503 is installed outside the threaded sleeve 502, the first connecting rod 504 is installed inside the connecting seat 503, the second connecting rod 505 is installed at the end of the first connecting rod 504 away from the connecting seat 503, and the clamping plate 506 is installed at the bottom end of the second connecting rod 505. When it is necessary to reinforce and strengthen the tire, the firmness, strength and elasticity of the tire can be improved through vulcanization. By placing the tire inside the fixed barrel 4 and placing the inner ring of the tire outside the limit frame 509, for the stability during vulcanization, by connecting the lead screw 501 to the output end of the driving motor, through the rotation of the lead screw 501, the threaded sleeve 502 descends outside the lead screw 501, causing the first connecting rod 504 and the second connecting rod 505 to expand, causing the clamping plate 506 to expand outward, making the clamping plate 506 tightly fit the inner wall of the tire, effectively preventing the tire from shifting during the vulcanization process.
[0029] Among them, please refer to Figure 1 , Figure 2 and Figure 3, in this embodiment, a fixing column 507 is installed at the top of the lead screw 501, and a connecting piece 508 is installed at the bottom end of the lead screw 501. A support column is installed between the fixing column 507 and the connecting piece 508. Through the design of the connecting piece 508 and the fixing column 507, the smoothness of the first connecting rod 504 and the second connecting rod 505 during expansion and contraction is greatly improved.
[0030] Furthermore, please refer to Figure 1 , Figure 2 and Figure 3 , in this embodiment, the connection mode between the top of the second connecting rod 505 and the fixing column 507 is a rotational connection. A rotating seat is installed inside the clamping plate 506, and the second connecting rod 505 is connected to the clamping plate 506 through the rotating seat. A limiting frame 509 is installed outside the support column. When the angle of the second connecting rod 505 during expansion tends to the maximum angle, the limiting frame 509 can be used for limiting, effectively preventing the second connecting rod 505 from folding upwards after expansion.
[0031] Furthermore, please refer to Figure 1 , Figure 4 and Figure 5 , in this embodiment, a connection disk 6 is installed at the bottom of the lid 3, a fixing frame 7 is installed at the bottom of the connection disk 6, and a cross plate 8 is installed at the bottom of the fixing frame 7. After the tire is clamped and fixed by the clamping plate 506, by starting the hanging bracket 1, the connection block 2 drives the lid 3 to block the top of the fixing barrel 4.
[0032] Furthermore, please refer to Figure 1 , Figure 4 and Figure 5, in this embodiment, a slide bar 9 is installed in the middle of the cross plate 8, a slide sleeve 10 is installed outside the slide bar 9, a connecting ear 11 is installed outside the slide sleeve 10, a clamping bar 12 is installed inside the connecting ear 11, a placement rack 13 is installed outside the clamping bar 12, a heating plate 14 is installed at one end of the clamping bar 12 away from the connecting ear 11, a linkage sleeve 15 is installed at the top of the connecting ear 11, a telescopic cylinder is installed at the top of the connecting plate 6, and the output end of the telescopic cylinder extends into the linkage sleeve 15. By the downward movement of the lid 3, the connecting plate 6 moves along with it, and the cross plate 8 contacts the fixed column 507. By starting the telescopic cylinder, the output end of the telescopic cylinder pushes the slide sleeve 10 to move, thereby driving the connecting ear 11 to move along with the slide sleeve 10. At the same time, through the design of the clamping bar 12 and the placement rack 13, the top end of the clamping bar 12 moves upward, and the bottom end of the clamping bar 12 is limited by the placement rack 13, so that the clamping bar 12 completes the work of contracting inward. In this way, the heating plate 14 wraps around the outside of the tire, and then follows the movement of the clamping bar 12 to realize uniform heating of the tire. Through the design of the linkage sleeve 15, the four clamping bars 12 move synchronously. At the same time, the suction pipe 401 is connected to the suction fan to adsorb the harmful gases generated by heating inside the fixed barrel 4, preventing the toxic gases from spreading to the outside of the operator after the fixation between the lid 3 and the fixed barrel 4 is released.
[0033] In this embodiment, the implementation scenario is specifically as follows: When it is necessary to reinforce and strengthen the tire, vulcanization can improve the firmness, strength, and elasticity of the tire. By placing the tire inside the fixed barrel 4 and placing the inner ring of the tire outside the limiting frame 509, for the stability during vulcanization, the lead screw 501 is connected to the output end of the drive motor. Through the rotation of the lead screw 501, the threaded sleeve 502 descends outside the lead screw 501, causing the first connecting rod 504 and the second connecting rod 505 to unfold, and the clamping plate 506 to expand outward, so that the clamping plate 506 tightly fits the inner wall of the tire, effectively preventing the tire from shifting during vulcanization. After the tire is clamped and fixed by the clamping plate 506, by starting the hanger 1, the connecting block 2 drives the lid 3 to block the top of the fixed barrel 4. As the lid 3 descends, the connecting plate 6 moves with it, and the cross plate 8 comes into contact with the fixed column 507. By starting the telescopic cylinder, the output end of the telescopic cylinder pushes the sliding sleeve 10 to move, thereby driving the connecting ear 11 to move with the sliding sleeve 10. At the same time, through the design of the clamping rod 12 and the placement rack 13, the top of the clamping rod 12 moves upward, and the bottom of the clamping rod 12 is limited by the placement rack 13, realizing the inward contraction of the clamping rod 12, and the heating plate 14 wraps around the outside of the tire, then follows the movement of the clamping rod 12 to achieve uniform heating of the tire. Through the design of the linkage sleeve 15, the four groups of clamping rods 12 move synchronously. At the same time, the suction pipe 401 is connected to the suction fan to adsorb the harmful gases generated by heating inside the fixed barrel 4, preventing the toxic gases from spreading to the outside of the operator after the fixation between the lid 3 and the fixed barrel 4 is released.
