Description

Technical Field

[0001] The invention relates to the field of tire vulcanizing equipment, and in particular to an internal pressure nitrogen heating device for a tire vulcanizer. Background Art

[0002] At present, a bladder method is known as a tire vulcanizer. In this method, a heating and pressurized medium such as steam or high-temperature gas (for example, inert gas such as nitrogen, or air) is supplied to the interior of a bladder. The bladder is expanded by the supply, thereby pressing the tire onto a mold, thereby vulcanizing the tire.

[0003] For example, the invention patent with publication number CN101578166B discloses a tire vulcanizer, comprising: a bladder for tire vulcanization arranged on the inner side of a tire blank; an ejection portion for ejecting a heated and pressurized medium into the bladder; a medium supply path for supplying the heated and pressurized medium to the ejection portion; and a retaining portion for retaining an edge of the bladder that is close to the medium supply path.

[0004] In the above case, when high-temperature nitrogen is filled into the capsule to expand the capsule, the outer wall of the capsule will come into contact with the inner wall of the tire. Affected by the temperature transmission, the outer temperature of the capsule is different from the inner temperature. Since the pressure inside the capsule is high and the gas fluidity inside the capsule is poor, it is easy to cause uneven distribution of heating temperature on the inner surface of the tire, which cannot achieve ideal uniformity, thereby affecting the consistency of tire vulcanization and product quality. In severe cases, it may even cause the tire to be scrapped.

[0005] To this end, the present invention proposes a tire vulcanizer internal pressure nitrogen heating device to solve the above problems. Summary of the invention

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a tire vulcanizer internal pressure nitrogen heating device, comprising:

[0007] A capsule, the outer wall of which is used to cover the tire body;

[0008] A stator, wherein the stator is arranged and connected in the capsule;

[0009] A rotor rotatably connected to the stator;

[0010] A plurality of fan blade modules, wherein the plurality of fan blade modules are fixedly connected in an annular array to the outer side wall of the rotor, a plurality of the intake pipes are arranged in a linear array on the end side wall of the fan blade module close to the rotor, and a plurality of the exhaust pipes are arranged in a linear array on the end side wall of the fan blade module away from the rotor;

[0011] A heating component, which is used to heat the gas sucked by the intake pipe, and transmit the heated gas to the exhaust pipe, through which the heated gas is discharged, so that the gas is sprayed toward the inner wall of the capsule to increase the temperature of the inner wall of the capsule;

[0012] Specifically, in the prior art, when the high-temperature nitrogen is filled into the capsule to expand the capsule, the outer wall of the capsule will come into contact with the inner wall of the tire. Affected by the temperature transmission, the outer temperature of the capsule is different from the inner temperature. Since the pressure in the capsule is relatively high, the gas fluidity in the capsule is relatively poor, which easily leads to uneven distribution of heating temperature on the inner surface of the tire and fails to achieve ideal uniformity, thereby affecting the consistency of tire vulcanization and product quality. In severe cases, the tire may even be scrapped. This technical solution can solve the above problems. The specific operation is as follows: first, the tire body is sleeved on the outer wall of the capsule, and then high-temperature nitrogen is transported into the capsule through a nitrogen delivery pipe to expand the capsule, and the inner wall of the tire body is squeezed to expand the tire body into a specified shape;

[0013] When the pressure inside the capsule reaches a specified parameter (i.e. the capsule expands to a specified state), current is passed through the induction coil in the stator, causing the rotor to drive the fan module to rotate, stirring the gas on the inner wall of the capsule through the fan module, increasing the fluidity of the gas in the capsule, thereby facilitating the temperature balance of the gas at various locations in the capsule, thereby facilitating the quality of the tire body;

[0014] In addition, by setting the suction pipe and the exhaust pipe, during the rotation of the fan blade module, the gas inside the capsule is first sucked in through the suction pipe, and the sucked gas is sent to the heating component for heating. Then the heating component sends the heated gas to the exhaust pipe, so that the exhaust pipe sprays high-temperature gas to the inner wall of the capsule, which is beneficial to increase the temperature of the inner wall of the capsule and further improve the quality of the tire body;

[0015] Moreover, during the process of the air intake pipe sucking in the gas in the capsule, the pressure in the capsule decreases, causing a slight decrease in the volume of the capsule. Then, the exhaust pipe re-injects the high-temperature gas into the capsule, the pressure in the capsule increases, and the capsule expands and returns to a specified state, thereby causing the capsule to expand and contract back and forth. On the one hand, this is beneficial to promoting the circulation of gas inside the capsule, so that the temperature inside the capsule is more uniform. On the other hand, the back-and-forth expansion and contraction of the capsule can better squeeze the inner wall of the tire body, which is beneficial to making the tire expand more regular, thereby improving the quality of the tire body.

DETAILED DESCRIPTION

[0069] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0070] like Figures 1 to 13 The tire vulcanizer internal pressure nitrogen heating device shown includes:

[0071] A capsule 1, the outer wall of which is used to cover a tire body 5;

[0072] An upper chuck 2, which is fixedly connected to the top of the capsule 1 and is used to clamp the top of the capsule 1;

[0073] A lower chuck 3, which is clamped at the bottom of the capsule 1 and is used to clamp the bottom end of the capsule 1;

[0074] A stator 6, which is arranged and connected in the capsule 1;

[0075] A T-shaped mounting seat 4, which is fixedly connected to the inner wall of the lower chuck 3, a nitrogen delivery pipe 401 and a nitrogen discharge pipe 402 are symmetrically fixedly connected in the T-shaped mounting seat 4, and a stator 6 is fixedly connected to the top of the T-shaped mounting seat 4;

[0076] A rotor 7, the rotor 7 is rotatably connected to the stator 6;

[0077] Several fan blade modules, several fan blade modules are annularly arrayed and fixedly connected to the outer side wall of the rotor 7, several air intake pipes 9 are linearly arrayed on the end side wall of the fan blade module close to the rotor 7, and several exhaust pipes 11 are linearly arrayed on the end side wall of the fan blade module away from the rotor 7;

[0078] A heating component is used to heat the gas sucked by the suction pipe 9, and transmit the heated gas to the exhaust pipe 11, and discharge the heated gas through the exhaust pipe 11, so that the gas is sprayed toward the inner wall of the capsule 1 to increase the temperature of the inner wall of the capsule 1;

[0079] Specifically, in the prior art, during the process of filling the capsule 1 with high-temperature nitrogen to expand the capsule 1, the outer wall of the capsule 1 will come into contact with the inner wall of the tire. Affected by the temperature transmission, the outer temperature of the capsule 1 is different from the inner temperature. Since the pressure in the capsule 1 is relatively high, the gas fluidity in the capsule 1 is relatively poor, which easily leads to uneven distribution of heating temperature on the inner surface of the tire and fails to achieve ideal uniformity, thereby affecting the consistency of tire vulcanization and product quality. In severe cases, the tire may even be scrapped. This technical solution can solve the above problems. The specific operation is as follows: first, the tire body 5 is sleeved on the outer wall of the capsule 1, and then high-temperature nitrogen is transported into the capsule 1 through the nitrogen delivery pipe 401 to expand the capsule 1, and the inner wall of the tire body 5 is squeezed to expand the tire body 5 into a specified shape.

[0080] When the pressure inside the capsule 1 reaches a specified parameter (i.e., the capsule 1 expands to a specified state), current is supplied to the induction coil in the stator 6, so that the rotor 7 drives the fan module to rotate, and the fan module stirs the gas on the inner wall of the capsule 1 to increase the fluidity of the gas in the capsule 1, which is beneficial to the balance of gas temperature at various locations in the capsule 1, thereby facilitating the improvement of the quality of the tire body 5;

[0081] In addition, by providing the suction pipe 9 and the exhaust pipe 11, during the rotation of the fan blade module, the gas inside the capsule 1 is first sucked in through the suction pipe 9, and the sucked gas is sent to the heating component for heating. Then the heating component sends the heated gas to the exhaust pipe 11, so that the exhaust pipe 11 sprays high-temperature gas to the inner wall of the capsule 1, thereby facilitating the temperature of the inner wall of the capsule 1 and further improving the quality of the tire body 5.

[0082] Furthermore, during the process of the air intake pipe 9 sucking in the gas in the capsule 1, the pressure in the capsule 1 decreases, causing a slight decrease in the volume of the capsule 1. Then, the exhaust pipe 11 re-injects the high-temperature gas into the capsule 1, the pressure in the capsule 1 increases, and the capsule 1 expands and recovers to a specified state, thereby causing the capsule 1 to expand and contract back and forth. On the one hand, this is beneficial to promoting the circulation of gas inside the capsule 1 so that the temperature inside the capsule 1 is more uniform. On the other hand, the back-and-forth expansion and contraction of the capsule 1 can better squeeze the inner wall of the tire body 5, which is beneficial to making the tire expand more regular, thereby improving the quality of the tire body 5.

[0087] Specifically, by providing the first U-shaped mounting frame 8, the second U-shaped mounting frame 10 and the folding blades 35, after the capsule 1 is expanded, the second U-shaped mounting frame 10 is turned over by starting the turning drive assembly, so that the folding blades 35 are unfolded, and the contact area between the folding blades 35 and the air inside the capsule 1 is increased, thereby promoting the circulation of the gas inside the capsule 1, and after the second U-shaped mounting frame 10 is unfolded, the exhaust pipe 11 can be close to the inner wall of the capsule 1, so as to facilitate the heated gas to act directly on the inner wall of the capsule 1, so as to increase the temperature of the inner wall of the capsule 1, so that the tire body 5 is heated evenly, and the quality of the tire body 5 is improved;

[0088] After the tire body 5 is vulcanized, the second U-shaped mounting frame 10 is flipped and reset by rotating the driving assembly, thereby reducing the space occupied by the fan blade module and facilitating the contraction of the bladder 1 .

[0116] After the second U-shaped mounting frame 10 is turned over, the sliding pin 2301 moves along the annular driving groove 2902, so that the push shell 23 stops moving. In addition, a first spring 25 is provided to elastically give way to the push block 26.

[0117] After the tire is vulcanized, the induction coil in the stator 6 is fed with a reverse current, causing the rotor 7 to reverse, thereby causing the push screw 29 to reverse, causing the push shell 23 to pull the push rod 24 to reset, and finally causing the second U-shaped mounting frame 10 to flip and reset.

[0118] As a further embodiment of the present invention, it also includes:

[0119] An arc-shaped limit plate 32, one end of which is slidably connected to the side wall of the bottom end of the first U-shaped mounting frame 8, and a second spring 33 is connected between the arc-shaped limit plate 32 and the first U-shaped mounting frame 8;

[0120] A limiting groove is provided in the arc-shaped limiting plate 32, and the limiting groove has an arc-shaped track groove 3201 and a straight groove 3202. A limiting rod 34 is slidably connected in the limiting groove, and the top end of the limiting rod 34 is fixedly connected to the bottom end of the second U-shaped mounting frame 10;

[0121] An L-shaped push frame 2302, which is fixedly connected to the outer side wall of the push shell 23;

[0122] Specifically, by setting the arc-shaped limiting plate 32 and the limiting groove, during the flipping process of the second U-shaped mounting frame 10, the limiting rod 34 slides along the arc-shaped track groove 3201, and when the second U-shaped mounting frame 10 flips to the specified position, the limiting rod 34 moves to the end of the arc-shaped track groove 3201, and then the pushing shell 23 continues to move, and the first spring 25 is compressed, and the pushing shell 23 drives the L-shaped pushing frame 2302 to push the arc-shaped limiting plate 32 to move, so that the limiting rod 34 moves into the straight groove 3202 and is limited by the straight groove 3202, thereby improving the stability of the second U-shaped mounting frame 10 when driving the folding blades 35 to rotate and stirring the air in the capsule.

[0123] The working principle of the present invention is as follows: firstly, the tire body 5 is sleeved on the outer wall of the capsule 1, and then high-temperature nitrogen is transported into the capsule 1 through the nitrogen delivery pipe 401 to expand the capsule 1 and squeeze the inner wall of the tire body 5 to expand the tire body 5 into a specified shape;

[0124] When the pressure inside the capsule 1 reaches a specified parameter (i.e., the capsule 1 expands to a specified state), current is supplied to the induction coil in the stator 6, so that the rotor 7 drives the fan module to rotate, and the fan module stirs the gas on the inner wall of the capsule 1 to increase the fluidity of the gas in the capsule 1, which is beneficial to the balance of gas temperature at various locations in the capsule 1, thereby facilitating the improvement of the quality of the tire body 5;

[0125] In addition, by providing the suction pipe 9 and the exhaust pipe 11, during the rotation of the fan blade module, the gas inside the capsule 1 is first sucked in through the suction pipe 9, and the sucked gas is sent to the heating component for heating. Then the heating component sends the heated gas to the exhaust pipe 11, so that the exhaust pipe 11 sprays high-temperature gas to the inner wall of the capsule 1, thereby facilitating the temperature of the inner wall of the capsule 1 and further improving the quality of the tire body 5.

[0126] Furthermore, during the process of the air intake pipe 9 sucking in the gas in the capsule 1, the pressure in the capsule 1 decreases, causing a slight decrease in the volume of the capsule 1. Then, the exhaust pipe 11 re-injects the high-temperature gas into the capsule 1, the pressure in the capsule 1 increases, and the capsule 1 expands and recovers to a specified state, thereby causing the capsule 1 to expand and contract back and forth. On the one hand, this is beneficial to promoting the circulation of gas inside the capsule 1 so that the temperature inside the capsule 1 is more uniform. On the other hand, the back-and-forth expansion and contraction of the capsule 1 can better squeeze the inner wall of the tire body 5, which is beneficial to making the tire expand more regular, thereby improving the quality of the tire body 5.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
