Description

Technical Field

[0001] This utility model relates to the technical field of heating and vulcanizing boxes for rubber sealing strips, and particularly to heating and vulcanizing boxes for the production of rubber sealing strips. Background Technology

[0002] Rubber sealing strips are a type of sealing material widely used in industry and daily life. They are mainly made of rubber and have good elasticity, flexibility and compression deformation ability. This elasticity allows the rubber sealing strip to fill gaps when squeezed, effectively preventing the passage of liquids, gases, dust, heat and so on, thus playing a sealing role. At the same time, different types of rubber materials give the sealing strips different properties such as temperature resistance, chemical corrosion resistance and aging resistance.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Rubber Vulcanizing Machine for Rubber Tube Production," with publication (announcement) number "CN219114544U." This patent mainly solves the problem that most vulcanizing devices are exposed to the elements during operation, where air dust and moisture have a significant impact on the vulcanization results, and the heating process is not qualitative. However, this patent is not convenient for evenly placing the rubber sealing strip in the vulcanizing box, resulting in uneven heating of the rubber sealing strip. It is also inconvenient to remove it from the vulcanizing box. Therefore, we propose a heated vulcanizing box for rubber sealing strip production. Utility Model Content

[0004] The purpose of this utility model is to provide a heating vulcanizing box for the production of rubber sealing strips, so as to solve the problems mentioned in the background art, such as the inconvenience of evenly placing the rubber sealing strips in the vulcanizing box, the uneven heating of the rubber sealing strips, and the inconvenience of taking them out of the vulcanizing box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating vulcanizing box for producing rubber sealing strips, comprising a vulcanizing box and a placement mechanism, wherein the placement mechanism comprises a placement box, the placement box is connected to a limit plate via a telescopic spring, and a middle winding shaft and two end winding shafts are fixedly installed on the inner wall of the placement box, and the two end winding shafts are connected to fixing bolts via threaded holes.

[0006] As a preferred embodiment, a transparent sealing cover is movably installed on the upper end of the vulcanizing box. An air inlet pipe is fixedly installed on one side of the upper surface of the transparent sealing cover, and an exhaust pipe is fixedly installed on the other side of its upper surface. The lower ends of both the air inlet pipe and the exhaust pipe extend into the interior of the vulcanizing box.

[0007] As a preferred embodiment, a transparent sealing cover is movably installed on the upper end of the vulcanizing box. An air inlet pipe is fixedly installed on one side of the upper surface of the transparent sealing cover, and an exhaust pipe is fixedly installed on the other side of its upper surface. The lower ends of both the air inlet pipe and the exhaust pipe extend into the interior of the vulcanizing box.

[0008] As a preferred embodiment, the intermediate winding shaft is located in the middle of the two winding shafts, and an arc-shaped pressure plate is sleeved on the outer wall of the two winding shafts. The threaded hole is opened inside the two winding shafts, and its upper end passes through the arc-shaped pressure plate. The fixing bolt is threadedly connected inside the threaded hole.

[0009] As a preferred embodiment, an exhaust treatment mechanism is provided on the outside of the vulcanizing box. The exhaust treatment mechanism includes a refrigeration box, and a heat exchange box is fixedly installed at the output end of the refrigeration box. The upper end of the heat exchange box is fixedly connected to the exhaust end of the exhaust pipe. A heat exchange tube is fixedly installed inside the heat exchange box, and the input end of the heat exchange tube is fixedly connected to the output end of the refrigeration box.

[0010] As a preferred embodiment, the exhaust end of the heat exchange box is fixedly connected to a solenoid valve, the lower end of the solenoid valve is fixedly installed with an activated carbon adsorption box, the output end of the heat exchange tube is fixedly connected to a circulation pipe, the end of the circulation pipe away from the heat exchange tube is fixedly installed with a circulation pump, the output end of the circulation pump is fixedly connected to the refrigeration unit, and the refrigeration unit, heat exchange box, activated carbon adsorption box and circulation pump are all fixedly installed on the outer wall of the vulcanization box.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] The placement mechanism, with the help of the telescopic spring, secures the placement box inside the vulcanizing box. This makes it very convenient to place the rubber sealing strip into the vulcanizing box for heating and vulcanization, and it is also easy to remove it after heating. The rubber sealing strip to be heated is wound around the central and end winding shafts, and then the fixing bolts and arc-shaped pressure plate are used to firmly fix the rubber sealing strip, preventing the rubber sealing strips from stacking on each other, thereby effectively improving the uniformity of heating of the rubber sealing strip.

[0013] The exhaust treatment mechanism allows the refrigerant in the refrigeration unit to circulate within the heat exchange tubes via a circulating pump, removing heat from the gas inside the heat exchange box. Simultaneously, the refrigeration unit can further cool the refrigerant after heat exchange before starting the next cycle, improving heat exchange efficiency and eliminating heat from the gas. Furthermore, by controlling the closing of the solenoid valve, the heat-exchanged gas can be introduced into the activated carbon adsorption box to remove harmful substances from the gas, ensuring that the discharged gas meets the standards.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0022] Please see the appendix Figure 1 - Appendix Figure 5A heating vulcanizing box for producing rubber sealing strips includes a vulcanizing box 1 and a placement mechanism 5. The placement mechanism 5 includes a placement box 501, which is connected to a limit plate 503 via a telescopic spring 502. A middle winding shaft 504 and two end winding shafts 505 are fixedly installed on the inner wall of the placement box 501. The two end winding shafts 505 are connected to fixing bolts 508 via threaded holes 507. A transparent sealing cover 2 is movably installed on the upper end of the vulcanizing box 1. An air inlet pipe 3 is fixedly installed on one side of the upper surface of the transparent sealing cover 2, while an exhaust pipe 4 is fixedly installed on the other side of its upper surface. The air inlet pipe 3 and the exhaust pipe 4 are also fixedly installed on the upper surface of the transparent sealing cover 2. The lower ends of the tubes 4 extend into the interior of the vulcanizing box 1. The bottom of the placement box 501 abuts against the inner bottom wall of the vulcanizing box 1. One end of the telescopic spring 502 is fixedly installed on the outer wall of the placement box 501. The limiting plate 503 is fixedly installed on the other end of the telescopic spring 502, and its outer wall abuts against the inner wall of the vulcanizing box 1. The middle winding shaft 504 is located in the middle of the two winding shafts 505. The outer walls of the two winding shafts 505 are fitted with arc-shaped pressure plates 506. The threaded hole 507 is opened inside the two winding shafts 505, and its upper end passes through the arc-shaped pressure plate 506. The fixing bolt 508 is threadedly connected inside the threaded hole 507.

[0023] The middle winding shaft 504 and the two end winding shafts 505 are the same size. The rubber sealing strips are wound sequentially on the middle winding shaft 504 and the two end winding shafts 505 to avoid overlap between the rubber sealing strips and increase the uniformity of heating. The use of telescopic springs 502 and limiting plates 503 makes it easy to place the box 501 and take it out of the vulcanizing box 1.

[0024] Specifically, the placement box 501 can be fixed inside the vulcanizing box 1 by the extension and retraction of the telescopic spring 502, which makes it convenient to put the rubber sealing strip into the vulcanizing box 1 for heating and vulcanization, and also makes it easy to take it out after heating. The rubber sealing strip to be heated is wound around the middle winding shaft 504 and the two end winding shafts 505, and then the rubber sealing strip is fixed by the fixing bolts 508 and the arc-shaped pressure plate 506 to prevent the rubber sealing strips from stacking together and improve the uniformity of heating of the rubber sealing strips. Example 2:

[0025] Please see the appendix Figure 1 and attached Figure 6Furthermore, based on Embodiment 1, an exhaust treatment mechanism 6 is provided on the outside of the vulcanizing box 1. The exhaust treatment mechanism 6 includes a refrigeration box 601. A heat exchange box 602 is fixedly installed at the output end of the refrigeration box 601. The upper end of the heat exchange box 602 is fixedly connected to the exhaust end of the exhaust pipe 4. A heat exchange tube 603 is fixedly installed inside the heat exchange box 602. The input end of the heat exchange tube 603 is fixedly connected to the output end of the refrigeration box 601. A solenoid valve 604 is fixedly connected at the exhaust end of the heat exchange box 602. An activated carbon adsorption box 605 is fixedly installed at the lower end of the solenoid valve 604. A circulation pipe 606 is fixedly connected at the output end of the heat exchange tube 603. A circulation pump 607 is fixedly installed at the end of the circulation pipe 606 away from the heat exchange tube 603. The output end of the circulation pump 607 is fixedly connected to the refrigeration box 601. The refrigeration box 601, the heat exchange box 602, the activated carbon adsorption box 605, and the circulation pump 607 are all fixedly installed on the outer wall of the vulcanizing box 1.

[0026] The solenoid valve 604 has a timer that is set to open at regular intervals. The time interval between openings is the time it takes for the discharged gas to cool down in the heat exchange box 602, so that the discharged gas can be fully heat-exchanged. The refrigeration unit 601 can quickly cool the refrigerant and ensure its heat exchange effect.

[0027] Specifically, the refrigerant in the refrigeration box 601 can be circulated in the heat exchange tube 603 by the circulation pump 607, which removes the heat from the gas in the heat exchange box 602. At the same time, the refrigerant after heat exchange can be cooled again by the refrigeration box 601 before the next cycle begins, which improves the heat exchange efficiency and removes the heat from the gas. Meanwhile, the gas after heat exchange can be introduced into the activated carbon adsorption box 605 by controlling the closing of the solenoid valve 604 to remove harmful substances from the gas, so that the discharged gas meets the standards.

[0028] Working principle of this utility model: This utility model is a heating vulcanizing box for the production of rubber sealing strips. First, one end of the rubber sealing strip is wound around the two lower winding shafts 505. The arc-shaped pressure plate 506 is placed on the outer wall, and the fixing bolts 508 are tightened in the threaded holes 507. Then, it is wound upwards along the middle winding shaft 504, with the end clamped on the two upper winding shafts 505. Similarly, the arc-shaped pressure plate 506 is placed on the outer wall, and the fixing bolts 508 are tightened in the threaded holes 507 to fix the rubber sealing strip. Then, the limiting plate 503 is pressed, causing the telescopic spring 502 to retract. Place the placement box 501 inside the vulcanizing box 1, cover it with the transparent sealing cover 2, open the vulcanizing box 1, and air enters through the air inlet pipe 3. After being heated, the air circulates inside the vulcanizing box 1, allowing the heat to be transferred to the rubber sealing strip. The internal air is discharged through the exhaust pipe 4 and enters the heat exchange box 602, where it exchanges heat with the heat exchange tube 603. The air enters the refrigeration box 601 under the action of the circulating pump 607 and is cooled again before starting the next cycle. The solenoid valve 604 will automatically open after a specified time. The cooled gas enters the activated carbon adsorption box 605, where harmful substances are adsorbed and then discharged into the atmosphere.
