Description

Technical Field

[0001] The invention relates to a hood-type heat-insulating cover of a tire vulcanizer and a working method thereof. Background Art

[0002] The mold insulation cover of the tire vulcanizer is mainly used to effectively insulate the vulcanization mold and heating plate of the tire vulcanizer. However, the tire vulcanizer insulation cover has the following problems:

[0003] 1. The insulation sleeve adopts a non-adjustable fixed structure. When replacing molds of different specifications or heights, it may cause the middle of the mold to be unable to keep warm (the middle will be detached);

[0004] 2. Due to the structural design defects of the insulation cover, the temperature outside the insulation cover is much higher than 40°C, and the insulation effect is poor;

[0005] 3. The current insulation sleeve only has an insulation effect when the mold is closed and vulcanization is in progress, but it has no insulation effect when the mold is opened (or the vulcanization bladder is straightened), and there is no cover to cover and extract the vulcanization fume (harmful, hot exhaust gas). There are a large number of tire vulcanizers in the current tire vulcanization plant, and all of them are directly discharged into the entire vulcanization plant, resulting in very high room temperature and fume concentration far exceeding the standard in the entire tire vulcanization plant, and the production and operation environment of the vulcanization plant is extremely poor.

[0006] In summary, the current tire vulcanizer mold insulation cover has the following disadvantages: 1. poor adjustability; 2. poor insulation effect; 3. no function of extracting vulcanization hot air and smoke. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a hood-type tire vulcanizer insulation cover and a working method thereof that can greatly reduce the outward diffusion of heat energy and have good thermal insulation effects, thereby reducing the flue gas concentration while lowering the room temperature in the vulcanization plant and improving the production environment.

[0008] The present invention is implemented by the following scheme: a cover-type tire vulcanizer insulation cover, comprising at least one vulcanization unit having an upper vulcanization mold and a lower vulcanization mold, wherein a lower fixed insulation cover is arranged around the periphery of the lower vulcanization mold, and an upper fixed insulation cover is arranged around the periphery of the upper vulcanization mold, wherein an upper movable insulation cover is provided on the outer side of the upper fixed insulation cover and can slide up and down relative to the upper fixed insulation cover, and an exhaust pipe is connected to the top of the upper fixed insulation cover.

[0009] Furthermore, the upper vulcanizing mold is equipped with a cylinder located above the upper movable thermal insulation sleeve for driving the upper movable thermal insulation sleeve to move up and down. The upper end of the upper movable thermal insulation sleeve is equipped with multiple guide wheels distributed at intervals along the circumference, and the outer side of the upper fixed thermal insulation sleeve is provided with a vertical track that cooperates with the guide wheel.

[0010] Furthermore, the exhaust pipe is connected to the exhaust main pipe, and the exhaust main pipe is connected to a vortex exhaust fan; the cylinder and the upper fixed insulation sleeve are both installed on the upper support plate of the upper vulcanization mold, and the lower fixed insulation sleeve is fixedly installed on the lower support plate of the lower vulcanization mold, and the outer diameter of the lower fixed insulation sleeve is slightly smaller than the inner diameter of the upper fixed insulation sleeve.

[0011] Furthermore, the lower fixed insulation cover, the upper fixed insulation cover and the upper movable insulation cover all include an insulation cover shell with an insulation interlayer in the middle. The insulation interlayer in the insulation cover shell is composed of two insulation material layers, one inner and one outer, with an air insulation layer left between the two insulation material layers.

[0012] Another technical solution of the present invention is a method for operating the above-mentioned enclosure-type tire vulcanizer insulation cover, comprising the following steps:

[0013] (1) When the vulcanizing unit is molded, the upper fixed insulation sleeve covers the lower fixed insulation sleeve, and the upper movable insulation sleeve shrinks to the upper position;

[0014] (2) When the vulcanization unit opens the mold, the vortex exhaust fan starts to suck the vulcanization fume. When the mold opens to a certain height, the cylinder drives the upper movable insulation sleeve to descend;

[0015] (3) When the tire vulcanizer's manipulator grabs the tire, the cylinder drives the upper movable insulation cover to retract upward to the upper position.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the heat insulation cover of the enclosing tire vulcanizer of the present invention is reasonably designed, highly practical, and has a wide range of applications. It greatly reduces the outward diffusion of heat energy, has good thermal insulation effects, prevents vulcanization waste gas from being directly discharged into the entire vulcanization plant, reduces the flue gas concentration while lowering the room temperature in the vulcanization plant, and improves the production environment.

DETAILED DESCRIPTION

[0027] like Figures 1 to 8 As shown, a hood-type tire vulcanizer insulation cover includes at least one vulcanization unit with an upper vulcanization mold 100 and a lower vulcanization mold 200, wherein the lower vulcanization mold 200 is provided with a lower fixed insulation cover 210 in a circle, and the upper vulcanization mold 100 is provided with an upper fixed insulation cover 110 in a circle. The upper fixed insulation cover 110 has an upper movable insulation cover 120 that can slide up and down relative to the upper fixed insulation cover 120, and the top of the upper fixed insulation cover 120 is connected to an exhaust pipe 310; the movable insulation cover on the hood-type tire vulcanizer insulation cover of the present invention can slide downward when the mold is opened, so that the vulcanization unit can be opened when the mold is opened. When the mold reaches a certain height (that is, the vulcanization bladder reaches the straightened state), the interior continues to remain in a relatively closed state, which can maximize the guarantee that the vulcanization bladder is in the straightened state and is insulated to prevent the heat from spreading outward, and also ensure that the vulcanization waste gas does not emit outward, greatly reducing the outward diffusion of heat energy and achieving good thermal insulation effects; at the same time, each vulcanization unit is equipped with an exhaust pipe to ensure that each vulcanization unit can independently draw air to prevent the vulcanization waste gas from being directly discharged into the entire vulcanization plant when the vulcanization unit opens the mold, thereby reducing the room temperature in the vulcanization plant while reducing the flue gas concentration and improving the production environment.

[0028] In this embodiment, the upper vulcanization mold 100 is equipped with a cylinder 400 located above the upper movable thermal insulation sleeve for driving the upper movable thermal insulation sleeve to move up and down. The upper end of the upper movable thermal insulation sleeve 120 is equipped with a plurality of guide wheels 121 distributed along the circumferential direction. The outer side of the upper fixed thermal insulation sleeve 110 is provided with a vertical track 111 that cooperates with the guide wheel 121, which can ensure that the movement of the upper movable thermal insulation sleeve is stable and reliable.

[0029] In this embodiment, the tire vulcanizer has two groups of vulcanizing units, one on the left and one on the right, each group has two layers of vulcanizing units, for a total of four vulcanizing units. Each vulcanizing unit has three cylinders 400 for driving the upper movable insulation sleeve to move up and down.

[0030] In this embodiment, the exhaust pipe 310 is connected to the exhaust main pipe 330, and the exhaust main pipe is connected to a vortex exhaust fan 500; and the vortex exhaust fan 500 can be turned on during the set operating period, and can ensure that the sulfurization waste gas is sucked away without being turned on for a long time or all the time. In this way, the number or time of turning on large-scale suction fans in the entire sulfurization plant can be greatly reduced, which can greatly save or reduce electricity (save energy), reduce the noise of the sulfurization plant, etc.

[0031] In this embodiment, the cylinder 400 and the upper fixed insulation sleeve 110 are both mounted on the upper support plate 130 of the upper vulcanization mold 100, and the lower fixed insulation sleeve 210 is fixedly mounted on the lower support plate 220 of the lower vulcanization mold 200; the outer diameter of the lower fixed insulation sleeve 210 is slightly smaller than the inner diameter of the upper fixed insulation sleeve 110, and the sum of the height of the upper fixed insulation sleeve 110 extending downward from the lower side of the upper support plate 130 and the height of the lower fixed insulation sleeve 210 extending upward from the upper side of the lower support plate 220 is greater than the upper The distance between the upper and lower supporting plates when the upper and lower vulcanizing molds are closed is so that the upper and lower fixed insulation sleeves have overlapping parts in the height direction when the upper and lower vulcanizing molds are closed; therefore, the height of the upper fixed insulation sleeve and the lower fixed insulation sleeve is increased, and the height of the overlapping part of the two can be increased. In addition, the upper movable insulation sleeve 120 that can slide up and down is added, so that the vulcanizing unit can meet the use requirements when replacing a mold with a higher height. It can basically be applied to all mold specifications that can be installed on all tire vulcanizers, and has a wide range of applications.

[0032] In this embodiment, the lower fixed insulation sleeve 210, the upper fixed insulation sleeve 110 and the upper movable insulation sleeve 120 all include an insulation sleeve shell 112 with an insulation interlayer in the middle, and the insulation interlayer in the insulation sleeve shell 112 is composed of two layers of insulation material 113, one inner and one outer, and an air insulation layer 114 is left between the two insulation material layers. The material of the insulation material layer is composed of glass fiber and polyurethane; the special structure of the lower fixed insulation sleeve 210, the upper fixed insulation sleeve 110 and the upper movable insulation sleeve 120 can greatly improve the insulation effect, save energy, and the temperature on the outer surface of the insulation sleeve can be controlled at about 40°C.

[0033] A method for operating the above-mentioned enclosure-type tire vulcanizer insulation cover comprises the following steps:

[0034] (1) When the vulcanizing unit is molded, the upper fixed insulation sleeve covers the lower fixed insulation sleeve, and the upper movable insulation sleeve shrinks to the upper position;

[0035] (2) When the vulcanization unit is opened, the command to control the vortex exhaust fan is issued, and the vortex exhaust fan starts to extract the vulcanization fume (hot air and exhaust gas). When the mold is opened to a certain height (that is, the vulcanization bladder is straightened), the command to control the cylinder is issued, and the cylinder drives the upper movable insulation cover to descend. The entire insulation cover continues to cover the vulcanization unit, which can ensure that the vulcanized tire bladder can be covered when it is straightened, and prevent the vulcanization fume (hot air and exhaust gas) from being emitted to the outside to the greatest extent. The time of issuing the command varies according to the height of the mold. The higher the mold, the earlier the command.

[0036] (3) When the robot of the tire vulcanizer grabs the tire, the cylinder drives the upper movable insulation cover to retract to the upper position, which makes it easier for the robot to grab the tire and also facilitates the vulcanization operation. After that, the upper movable insulation cover remains in the upper position until the next round of mold closing and vulcanization begins.

Therefore, the present invention discloses some numerical values ​​to illustrate the technical solutions of the present invention. Moreover, the numerical values ​​listed above should not be construed as limiting the scope of protection of the present invention.

[0038] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding).
