Technical Field

[0001] This utility model belongs to the field of rubber roller processing technology, specifically relating to a secondary vulcanization treatment device for rubber roller processing. Background Technology

[0002] Rubber rollers are a key component widely used in many industrial fields. They are mainly composed of an outer rubber layer, a hard rubber layer, a metal core, a roller neck, and ventilation holes. The processing includes multiple steps such as roller core sandblasting, bonding treatment, rubber forming, cloth wrapping, wire winding, vulcanization in a vulcanizing tank, and surface finishing. In the vulcanization process of rubber rollers, electric heating is usually used to perform secondary vulcanization.

[0003] According to the authorization announcement number CN212472127U, a vulcanizing device for rubber roller processing is known prior art. Although this patent has the advantage of being able to flip the rubber roller so that it is fully heated and thus improves the vulcanization effect, the technical solution of this patent still has the following defects in actual use: when loading the rubber roller, the support shaft needs to be passed through the rubber roller first, then the position of the rubber roller is limited by the retaining ring, and finally the locking plate is tightened to fix the rubber roller. This method of loading and fixing the rubber roller makes the operation process relatively cumbersome, which will cause inconvenience to the fixed placement of the rubber roller. Therefore, we propose a secondary vulcanization treatment device for rubber roller processing. Utility Model Content

[0004] The purpose of this invention is to provide a secondary vulcanization treatment device for rubber roller processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a secondary vulcanization treatment device for rubber roller processing, comprising an oven, a rotating assembly at the bottom of the oven, a rotating tube fixedly connected to the top of the rotating assembly, an installation ring fixedly sleeved on the outside of the rotating tube, a rubber roller clamp fixedly connected to the front of the installation ring, a heating plate fixedly installed on one side of the oven cavity, and a hot air circulation assembly provided on the other side of the oven cavity.

[0006] In a preferred embodiment, the oven has a door that is hinged to the front, and a support base that is fixedly connected to the bottom of the oven.

[0007] In a preferred embodiment, the rotating assembly includes a rotating shaft and a support block. The rotating shaft is movably sleeved on the bottom of the oven, and the support block is fixedly connected to the bottom of the oven cavity. A rotating motor is fixedly connected to the bottom end of the rotating shaft, and a turntable is fixedly connected to the top end of the rotating shaft. The bottom of the turntable is in contact with the top of the support block, and the top of the turntable is fixedly connected to the bottom of the rotating tube.

[0008] In a preferred embodiment, the top end of the rotating tube is movably sleeved on the top of the oven, and the surface of the rotating tube is provided with a through hole.

[0009] In a preferred embodiment, the rotating tube and the mounting ring are fixedly connected by a mounting rod, and the rubber roller clamp is made of an elastic material.

[0010] In a preferred embodiment, the hot air circulation assembly includes an air intake pipe, which is fixedly connected to the other side of the oven cavity. An air intake hood is fixedly installed on one side of the air intake pipe. A purification box is threaded to one end of the air intake pipe. An activated carbon layer is laid inside the purification box. An exhaust pipe is threaded onto the top of the purification box. One end of the exhaust pipe is movably connected to the top of the rotating tube. An exhaust pump is fixedly installed on the outside of the exhaust pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] Please see Figure 2 and Figure 3 This utility model provides a secondary vulcanization treatment device for rubber roller processing, including an oven 1 and a rotating tube 3. The front of the oven 1 is movably connected to a door via a hinge, and the bottom of the oven 1 is fixedly connected to a support base. The top end of the rotating tube 3 is movably sleeved on the top of the oven 1, and a through hole is opened on the surface of the rotating tube 3. An installation ring 4 is fixedly sleeved on the outside of the rotating tube 3. A rubber roller clamp 5 is fixedly connected to the front of the installation ring 4. The rotating tube 3 and the installation ring 4 are fixedly connected by an installation rod 6. The rubber roller clamp 5 is made of an elastic material.

[0021] In this embodiment, when the oven door is opened, the rubber roller to be vulcanized is placed inside the oven 1, so that the two ends of the rubber roller are aligned with the corresponding upper and lower rubber roller clamps 5, and the rubber roller is pressed and force is applied so that the rubber roller and the rubber roller clamp 5 come into contact. The rubber roller clamp 5 will deform and expand due to the squeezing force. At this time, the rubber roller will be stuck inside the rubber roller clamp 5. In this way, the rubber roller to be vulcanized can be squeezed and fixed by the rubber roller clamp 5. Moreover, the operation of this rubber roller loading and fixing method is simple, thus bringing convenience to the fixed placement of the rubber roller.

[0022] Please see Figure 1 and Figure 2 The bottom of the oven 1 is provided with a rotating component 2, and the top of the rotating component 2 is fixedly connected with a rotating tube 3. The rotating component 2 includes a rotating shaft 21 and a support block 22. The rotating shaft 21 is movably sleeved on the bottom of the oven 1, and the support block 22 is fixedly connected to the bottom of the inner cavity of the oven 1. The bottom end of the rotating shaft 21 is fixedly connected with a rotating motor 23, and the top end of the rotating shaft 21 is fixedly connected with a turntable 24. The bottom of the turntable 24 is in contact with the top of the support block 22, and the top of the turntable 24 is fixedly connected to the bottom of the rotating tube 3. A heating plate 7 is fixedly installed on one side of the inner cavity of the oven 1.

[0023] In this embodiment, after the rubber roller to be vulcanized is loaded and fixed, the box door is closed, the circuit of the heating plate 7 is turned on, so that the heating plate 7 generates heat due to power and heats the air inside the oven 1. At the same time, the rotary motor 23 is turned on, so that the rotary shaft 21 rotates, and the rotary shaft 21 drives the turntable 24 to rotate, and the turntable 24 drives the rotary tube 3 to rotate, so that the rotary tube 3 drives the rubber roller fixed on the mounting ring 4 to rotate through the mounting rod 6, so that the rubber roller can be fully heated, thereby facilitating the secondary vulcanization treatment of the rubber roller.

[0024] Please see Figure 1 and Figure 2 A hot air circulation assembly 8 is provided on the other side of the inner cavity of oven 1. The hot air circulation assembly 8 includes a suction pipe 81, which is fixedly connected to the other side of the inner cavity of oven 1. A suction hood 82 is fixedly installed on one side of the suction pipe 81. A purification box 83 is threaded to one end of the suction pipe 81. An activated carbon layer 84 is laid inside the purification box 83. An exhaust pipe 85 is threaded to the top of the purification box 83. One end of the exhaust pipe 85 is movably connected to the top of the rotating tube 3. An exhaust pump 86 is fixedly installed on the outside of the exhaust pipe 85.

[0025] In this embodiment, when the rubber roller is undergoing heat vulcanization, the vacuum pump 86 is activated, and the vacuum pipe 85 is used to evacuate the interior of the purification box 83. At this time, negative pressure is generated inside both the purification box 83 and the suction pipe 81, and the suction hood 82 will generate suction due to the negative pressure, allowing the hot air in the oven 1 to enter the interior of the purification box 83 through the suction pipe 81. The activated carbon layer 84 in the purification box 83 will adsorb and filter the odor molecules in the hot air, and the filtered hot air will be input into the interior of the rotating tube 3 through the vacuum pipe 85, allowing the hot air to flow out from the through holes on the surface of the rotating tube 3. This can heat the inside of the rubber roller, further ensuring that the surface of the rubber roller is fully heated, thereby improving the secondary vulcanization effect of the rubber roller.

[0026] The working principle and usage process of this utility model are as follows: First, open the box door and put the rubber roller to be vulcanized into the oven 1, so that the two ends of the rubber roller are aligned with the corresponding rubber roller clamps 5 on the upper and lower sides respectively, and press the rubber roller to make the rubber roller and the rubber roller clamps 5 come into contact. The rubber roller clamps 5 will deform and expand due to the squeezing force. At this time, the rubber roller will be stuck into the inside of the rubber roller clamps 5. In this way, the rubber roller to be vulcanized can be squeezed and fixed by the rubber roller clamps 5.

[0027] Next, close the oven door, turn on the circuit of the heating plate 7, so that the heating plate 7 generates heat due to power and heats the air inside the oven 1. At the same time, turn on the rotary motor 23, so that the rotary shaft 21 rotates, and the rotary shaft 21 drives the turntable 24 to rotate, and the turntable 24 drives the rotary tube 3 to rotate, so that the rotary tube 3 drives the rubber roller fixed on the mounting ring 4 to rotate through the mounting rod 6, so that the rubber roller can be fully heated.

[0028] Finally, the vacuum pump 86 is started, and the vacuum pipe 85 is used to evacuate the inside of the purification box 83. At this time, negative pressure will be generated inside the purification box 83 and the vacuum pipe 81, and the vacuum hood 82 will generate suction due to the negative pressure, so that the hot air in the oven 1 can enter the inside of the purification box 83 through the vacuum pipe 81. The activated carbon layer 84 in the purification box 83 will adsorb and filter the odor molecules in the hot air, and the filtered hot air will be input into the inside of the rotating tube 3 through the vacuum pipe 85, so that the hot air can flow out from the through holes on the surface of the rotating tube 3. This can heat the inside of the rubber roller, and further ensure that the surface of the rubber roller is fully heated, thereby improving the secondary vulcanization effect of the rubber roller.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
