Description

Technical Field

[0001] The utility model relates to the technical field of internal mixers, in particular to an internal mixer for rubber. Background Art

[0002] Internal mixers are widely used in the rubber industry for mixing, plasticizing and refining various rubber raw materials. Its main application scenarios include rubber product production, rubber recycling, rubber recycling processing and other fields. In the production of rubber products, internal mixers are used to fully mix different types of rubber raw materials with additives to obtain rubber mixtures that meet specific requirements. For example, in the production of tires, seals, rubber tubes and other products, internal mixers are required for pretreatment of rubber materials.

[0003] An existing environmentally friendly, low-loss internal mixer comprises a base; an internal mixer body, which is mounted on the base; an exhaust pipe, which is mounted on the internal mixer body; a mounting seat, which is fixedly connected to the base, with two slots provided at the upper end of the mounting seat, and sliding holes provided at both the front and rear ends of the mounting seat; a filter body, which is arranged on the exhaust pipe, with two groups of plug rods fixedly connected to the lower end of the filter body, and each group of plug rods is provided with two, and each of the plug rods is provided with two positioning holes; a mounting mechanism, which is provided with two groups of mounting mechanisms, and both groups of mounting mechanisms are provided on the slots.

[0004] In the actual practical process of the above-mentioned related technology, the staff needs to hold the two card plates in one hand and pull the two card plates outward at the same time. The movement of the card plates stretches the second spring and then detaches the card plates from the surface of the skateboard. Then, the skateboard is held with the other hand and pulled inward. The movement of the skateboard drives the push plate to move, and the movement of the push plate drives the positioning block to move. The push plate will compress the first spring while moving, and the movement of the positioning block will cause the positioning block to detach from the positioning hole, thereby achieving the purpose of disassembly. After the above series of operations, only one side of the filter is released. At this time, the staff still cannot disassemble the filter, and another staff is needed to release the fixation of the filter on the other side. It takes two staff members to cooperate to disassemble the filter, and the disassembly efficiency is low, which increases labor costs. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] refer to Figure 1-5 , a rubber internal mixer comprises a base 1 and an exhaust gas processor 2. A mixing chamber 101 is provided on the base 1, an air outlet 102 is provided on the mixing chamber 101, and a fixing block 103 is provided around the air outlet 102. A mounting plate 201 is provided at the bottom of the exhaust gas processor 2, and the mounting plate 201 can be connected to the exhaust gas processor 2 by bolts. The bolt connection can facilitate the staff to separate the mounting plate 201 from the exhaust gas processor 2, or install different types of exhaust gas processors 2 on the mounting plate 201, thereby improving the scope of application. A plurality of fixing plates 202 are provided at the bottom of the mounting plate 201, and each fixing plate 202 is provided with a card slot 203. The fixing plate 202 is provided with a fixing slot 204 for installing the fixing plate 202. The setting of the fixing slot 204 can help the staff to quickly position the exhaust gas processor 2, thereby facilitating the installation of the staff. A fixing mechanism is provided on both sides of the fixing block 103, and the fixing mechanism includes two telescopic components for being connected with the card slot 203 and a limiting component for limiting each telescopic component.

[0026] Specifically, there are at least four fixing plates 202, and the four fixing plates 202 are respectively arranged at the four corners of the bottom of the mounting plate 201. By setting the four fixing plates 202 at the four corners, the bottom support of the exhaust gas processor 2 is more uniform and stable, which can effectively prevent the equipment from shaking or tilting during operation, thereby improving the stability of the equipment.

[0027] The limit assembly can be set to prevent the telescopic assembly from automatically rebounding, thereby facilitating the staff to disassemble the exhaust gas processor 2. The telescopic assembly includes a telescopic block 3, an elastic member 301, and a pull rod 302. The elastic member 301 is a cylindrical compression spring. The cylindrical compression spring can provide reliable elastic support and restoring force to ensure that the telescopic block 3 can be telescoped. A telescopic groove 303 is provided on one side of the fixed groove 204. The telescopic block 3 is arranged in the telescopic groove 303 and is slidably connected to the inner wall of the telescopic groove 303.

[0028] When the telescopic block 3 moves toward the direction of the compression elastic member 301 driven by the handle 304, the telescopic block 3 will be slidably connected with the inner wall of the telescopic slot 303. In order to improve the stability of the movement of the telescopic assembly, refer to Figure 5Guide blocks 402 are provided on both sides of the telescopic block 3, and guide grooves 403 are provided on both sides of the telescopic groove 303. The guide blocks 402 are slidably connected to the inner walls of the guide grooves 403. The guide blocks 402 and guide grooves 403 are provided to prevent the telescopic block 3 from being offset during the movement, thereby improving the stability of the movement of the telescopic block 3.

[0029] One end of the elastic member 301 abuts against the bottom of the telescopic groove 303, and the other end of the elastic member 301 abuts against the telescopic block 3. The pull rod 302 is arranged on the side of the telescopic block 3 close to the elastic member 301, and the elastic member 301 is sleeved on the pull rod 302. The side of the pull rod 302 of the two telescopic components away from the telescopic block 3 both passes through the side of the fixed block 103 and is fixedly connected with a handle 304.

[0030] When the staff needs to clean the exhaust gas treatment device 2, they only need to hold the handle 304 and pull it outward. The handle 304 will drive the telescopic block 3 to move in the direction of the compression elastic member 301 through the pull rod 302, so that the telescopic block 3 will be disengaged from the slot 203 on the fixed block 103. Once the telescopic block 3 is disengaged from the slot 203, the staff can use the limit assembly to fix the position of the telescopic block 3 to prevent the telescopic block 3 from returning to the slot 203 again under the action of the elastic member 301 when the handle 304 is released. At this time, the staff only needs to unfasten the fixation on one side of the exhaust gas treatment device 2, and the same is true for the other side. When the staff pulls open the handle 304 on the other side, the exhaust gas treatment device 2 can be taken out. This design allows only one staff member to complete the disassembly of the exhaust gas treatment device 2, which is easy to operate, reduces labor costs, and improves practicality.

[0031] In this embodiment, the limit assembly includes a limit screw 4 and a limit nut 401. The limit screw 4 is arranged on the side of the fixed block 103, and the limit nut 401 is arranged on the limit screw 4 and is threadedly connected to the limit rod, and the limit nut 401 is in contact with the handle 304. The limit assembly can prevent the telescopic block from returning to the slot 203 again under the action of the elastic member 301 when the handle 304 is loosened, thereby facilitating the staff to disassemble the exhaust gas processor 2. When the staff pulls open the handle 304 with one hand and disengages the telescopic block 3 from the slot 203, the other hand rotates the limit nut 401 to make the side of the limit nut 401 abut against the side of the handle 304. Since the limit screw 4 and the limit nut 401 are threadedly connected, and the threaded connection is self-locking, the limit nut 401 can prevent the telescopic block 3 from rebounding.

[0032] In this embodiment, in order to facilitate the staff to quickly install the exhaust gas processor 2, a first inclined surface 5 is provided on the side of the telescopic block 3 away from the elastic member 301, and a second inclined surface 501 is provided at the bottom of the fixed plate 202 to be slidably connected to the first inclined surface 5. When the staff inserts the fixed plate 202 at the bottom of the mounting plate 201 into the fixed groove 204 and pushes it inward, through the first inclined surface 5 and the second inclined surface 501, the staff only needs to overcome the force of the elastic member 301 and the friction between the side of the telescopic block 3 and the inner wall of the telescopic groove 303 to quickly install the exhaust gas processor 2, which is convenient to operate. In order to reduce the friction between the side of the telescopic block 3 and the inner wall of the telescopic groove 303, a plurality of ball bearings 502 are provided at the bottom of the telescopic groove 303. When the staff installs and uses the second inclined surface 501 on the fixed plate 202 to squeeze the first inclined surface 5, the ball bearings 502 are slidably connected to the bottom of the telescopic block 3, thereby reducing the friction and facilitating quick installation by the staff. In order to increase the service life of the telescopic block 3, the top of one end of the telescopic block 3 provided with the first inclined surface 5 is formed into an arc-shaped structure. The telescopic block 3 with an arc-shaped structure can reduce the contact area with the side of the fixed plate 202, thereby reducing friction and further increasing the service life.

[0033] Staff: When the staff needs to disassemble the exhaust gas processor 2, they only need to hold the handle 304 and pull it outward. The handle 304 will drive the telescopic block 3 to move in the direction of the compressed elastic member 301 through the pull rod 302, so that the telescopic block 3 is separated from the slot 203 on the fixed block 103. Once the telescopic block 3 is separated from the slot 203, the staff can use the limit assembly to fix the position of the telescopic block 3 to prevent the telescopic block 3 from returning to the slot 203 again under the action of the elastic member 301 when the handle 304 is released. At this time, the staff only needs to unfasten the fixation on one side of the exhaust gas processor 2, and the same applies to the other side. When the staff pulls open the handle 304 on the other side, the exhaust gas processor 2 can be taken out;

[0034] During installation, it is only necessary to align the fixing plate 202 at the bottom of the mounting plate 201 with the fixing groove 204 and insert it, and the exhaust gas processor 2 can be quickly installed by overcoming the force of the elastic member 301, which is easy to operate.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
