Description

Technical Field

[0001] The utility model relates to the technical field of tire vulcanization, in particular to a smoke collecting device. Background Art

[0002] Tire vulcanization is one of the most important links in the tire manufacturing process. After the tire is vulcanized, the mold is opened and the tire will produce a lot of waste gas. Over time, a large amount of pungent smoke will gather in the factory. Therefore, it is necessary to collect and treat the smoke generated after vulcanization. There are many ways to collect smoke, such as whole-plant collection, room collection, etc.

[0003] In the factory-style collection, operators need to install processing equipment outside the factory, extend the pipeline deep into the factory, and collect the smoke from the entire factory. Due to the large internal space of the factory, the smoke distribution space is too wide, and the smoke collection effect is not good. In addition, the large exhaust space also causes problems such as large fan air volume and high energy consumption. In the room-style collection, it is necessary to cover a room outside the vulcanizer and use the exhaust pipe to extract smoke, which also has problems such as high energy consumption and low efficiency. It can be seen that these collection methods all require a large three-dimensional space, consume a lot of energy, and have average collection effects, and cannot achieve efficient and convenient smoke collection.

[0004] Therefore, there is an urgent need for a smoke collection device to solve the above technical problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a fume collecting device, which is arranged between an upper die table 101 and a lower die table 102 of a vulcanizer 100, and the upper die table 101 is connected to the lower die table 102 in a liftable manner, and the fume collecting device includes a sleeve 10 and an exhaust mechanism 20. A plurality of sleeves 10 are provided, and the plurality of sleeves 10 are sequentially sleeved and connected to each other in the vertical direction. In the vertical direction, the sleeve 10 at the top is connected to the upper die table 101, and the sleeve 10 at the bottom can abut against the lower die table 102. The plurality of sleeves 10 are interconnected and provided with a containing cavity 11. By lifting and moving the upper die table 101 relative to the lower die table 102, the volume of the containing cavity 11 can be adjusted, and the output end of the exhaust mechanism 20 is detachably connected to the containing cavity 11.

[0032] In this embodiment, there are multiple sleeves 10, and the multiple sleeves 10 are sequentially sleeved and connected in the vertical direction. The interiors of the multiple sleeves 10 are interconnected to form a accommodating chamber 11 for accommodating smoke. The multiple sleeves 10 can be telescoped in the vertical direction to adjust the volume of the accommodating chamber 11, so as to collect smoke and prevent smoke from diffusing and exposing. In the vertical direction, the sleeve 10 at the top is connected to the upper die table 101, and the sleeve 10 at the bottom can abut against the lower die table 102 and be covered on the lower die table 102 to form the accommodating chamber 11. By lifting and moving the upper die table 101 relative to the lower die table 102, the volume of the accommodating chamber 11 can be adjusted to adapt to the vulcanization operation of the tire and ensure the collection effect of smoke. The output end of the exhaust mechanism 20 is detachably connected to the accommodating chamber 11, and the smoke in the accommodating chamber 11 is sucked out by the exhaust mechanism 20, so as to improve the collection efficiency of smoke and facilitate maintenance and replacement. Through the above arrangement, the smoke collecting device of this embodiment can efficiently and conveniently collect the smoke generated by the tire during the vulcanization process, and the collection effect is better.

[0033] It should be noted that the upper die table 101 is connected to the lower die table 102 in a liftable manner, which can be achieved specifically by a hydraulic cylinder or a pneumatic cylinder. Those skilled in the art are aware of the specific working principle of the vulcanizer 100 and will not be elaborated herein.

[0034] Specifically, among two adjacent sleeves 10, one sleeve 10 is provided with a slide groove extending in the vertical direction, and the other sleeve 10 is provided with a sliding member, which is slidably connected in the slide groove. Through the sliding connection between the sliding member and the slide groove, each two adjacent sleeves 10 can slide relative to each other, thereby facilitating the adjustment of the volume of the entire accommodating cavity 11. The sliding member can be a slider or a slide bar, that is, the specific structure of the sliding member is not limited.

[0035] Specifically, Figure 1 and Figure 2As shown, in this embodiment, the sleeve 10 includes a first barrel body 1 and a second barrel body 2, the first barrel body 1 is connected to the upper mold platform 101, the second barrel body 2 is sleeved on the outer peripheral wall of the first barrel body 1, and is slidably connected to the first barrel body 1 along the vertical direction. When the upper mold platform 101 is raised and lowered relative to the lower mold platform 102 to realize the vulcanization operation, it will drive the first barrel body 1 to move relative to the second barrel body 2 along the vertical direction, thereby adjusting the size of the accommodating cavity 11 to adapt to the collection of smoke. It can be understood that when the upper mold platform 101 rises, the first barrel body 1 slides upward relative to the second barrel body 2, and the volume of the accommodating chamber 11 increases until it remains unchanged. At this time, the second barrel body 2 no longer abuts against the lower mold platform 102, and rises to a certain height to facilitate the operator to place the tire in the accommodating chamber 11. After the tire is placed in the accommodating chamber 11, the upper mold platform 101 descends to drive the first barrel body 1 to slide downward, and the second barrel body 2 can abut and cover the lower mold platform 102 to form the accommodating chamber 11. As the first barrel body 1 continues to move downward, the first barrel body 1 slides and extends into the second barrel body 2, so that the volume of the accommodating chamber 11 is reduced, thereby adapting to the normal operation of the vulcanizer 100 and ensuring that the smoke can be effectively collected and prevented from spreading.

[0036] More specifically, in other embodiments, the specific number of the sleeves 10 is not limited, and may be three, four or five, etc., by sequentially arranging and slidingly connecting the multiple sleeves 10 to ensure that the volume of the accommodating chamber 11 is flexibly adjustable, thereby facilitating the collection and discharge of smoke.

[0037] Specifically, Figure 1 and Figure 2 As shown, the smoke collection device also includes a wear-resistant strip 3, which extends in the vertical direction and is arranged on the outer wall of the first barrel body 1. The wear-resistant strip 3 is sandwiched between the first barrel body 1 and the second barrel body 2, which can reduce the wear generated during the sliding process and reduce the maintenance cost. The wear-resistant strip 3 is provided with a slideway along its own extension direction, and the inner wall of the second barrel body 2 is provided with a convex ridge that slides with the slideway. The convex ridge is slidably connected to the slideway, which can effectively reduce the friction resistance between the first barrel body 1 and the second barrel body 2, and improve the smoothness and stability of the sliding. Among them, the wear-resistant strip 3 is made of polyethylene material, which has the advantages of scratch resistance, aging resistance, high and low temperature resistance, and friction resistance.

[0038] More specifically, if Figure 1 and Figure 2 As shown, the smoke collecting device further comprises a reinforcing plate 4, and the wear-resistant strip 3 is screwed to the first barrel 1 through the reinforcing plate 4. Figure 2As shown, the wear-resistant strip 3, the reinforcing plate 4 and the first barrel body 1 are screwed in sequence by screws, which is not only convenient to install, but also has a firm and reliable connection, which is convenient for the disassembly and maintenance of each component. The reinforcing plate 4 is sandwiched between the wear-resistant strip 3 and the first barrel body 1, which can ensure the connection strength between the components and avoid the wear-resistant strip 3 being directly installed on the outer wall of the first barrel body 1, resulting in unstable connection. Among them, the reinforcing plate 4 is usually made of high-strength, corrosion-resistant materials, such as steel plates or composite materials.

[0039] Specifically, Figure 1 and Figure 2 As shown, the smoke collection device also includes a limit member 5, which is arranged on the second barrel body 2. When the first barrel body 1 slides to a predetermined position, the first barrel body 1 can abut against the limit member 5, thereby limiting the first barrel body 1 from further sliding relative to the second barrel body 2, preventing it from excessive sliding or dislocation, and ensuring the stability and safety of the device.

[0040] More specifically, if Figure 2 As shown, in this embodiment, the stopper 5 is a retaining ring, which is arranged at one end of the second barrel 2 facing the upper die table 101. By setting the retaining ring, one end of the first barrel 1 facing the lower die table 102 can abut against the retaining ring in the circumferential direction, thereby limiting the sliding range of the first barrel 1, ensuring the stability of the smoke collection device during operation, and enabling it to better adapt to the process requirements of tire vulcanization. In other embodiments, the stopper 5 is a stopper, and the above function is achieved by abutting the first barrel 1 against the stopper, that is, the specific structure of the stopper 5 is not limited.

[0041] Specifically, the exhaust mechanism 20 includes an exhaust pipe 201 and an exhaust fan, and the output end of the exhaust fan is connected to the accommodating chamber 11 through the exhaust pipe 201, thereby effectively extracting the smoke in the accommodating chamber 11. The exhaust fan can be a centrifugal exhaust fan or a vortex exhaust fan, and those skilled in the art are aware of the specific principles of the exhaust fan, which will not be described in detail here.

[0042] More specifically, one end of the air extraction pipe 201 is magnetically connected to the sleeve 10 to facilitate the removal and installation of the air extraction pipe 201 .

[0043] Specifically, the sleeve 10 is provided with an air inlet hole, and the accommodating chamber 11 is connected to the outside through the air inlet hole, thereby maintaining the pressure balance between the inside of the accommodating chamber 11 and the external environment, thereby ensuring the smoke suction effect.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
