Description

Technical Field

[0001] This utility model relates to the field of rubber compounding technology, specifically to a rubber filtering device for rubber compounding. Background Technology

[0002] Compounded silicone rubber is a basic rubber compound formulated based on methyl or vinyl-containing linear polymers of polyorganosiloxane (commonly known as raw rubber), combined with reinforcing fillers, volume-enhancing fillers, and additives that impart various properties. The main raw material is methyl or vinyl raw rubber, with the addition of silica, crosslinking agents, structure control agents, coupling agents, and other materials, mixed in a high-temperature internal mixer. Filtration is required during the production of the compounded rubber.

[0003] For example, Chinese Patent Publication No. CN219902907U discloses a rubber filtering device for rubber compounds, relating to the field of rubber compound technology. It includes a support mechanism, with a filtering mechanism fixedly connected inside the support mechanism, and a pressure mechanism fixedly connected to the top of one side of the support mechanism. This invention filters larger impurities in the rubber compound through a filter screen, filters smaller impurities through filter cotton, and further filters the rubber compound through a filter plate. This multi-stage filtration method improves the filtration effect. The filtered impurities enter a storage box through a discharge hole for storage. The storage box can then be removed for cleaning by pulling the handle and opening the discharge door, making discharge more convenient. This solves the problem that when filtering viscous rubber compounds, a single-layer filter screen cannot completely filter out impurities, and the filtered impurities are difficult to discharge, causing inconvenience in use.

[0004] After using the rubber filtering device, it was found that although the device can filter rubber and the filter screen is tilted, some of the rubber compound will fall directly into the storage box without passing through the filter screen, which will cause a lot of waste and is not very practical. Utility Model Content

[0005] The purpose of this invention is to provide a rubber filtering device for rubber compounding, so as to solve the problem of significant waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber filtering device for rubber compound, comprising a base and a filtering mechanism, wherein the base and the filtering mechanism are fixedly connected, a rotating shaft is rotatably connected to the middle of the filtering mechanism, a side plate is fixedly connected to the side of the rotating shaft, a slide rail is fixedly connected to the side of the side plate, a filter screen is slidably connected between the slide rails, a gear is fixedly connected to the outer wall of the rotating shaft, a slide bar is fixedly connected to the top of the base, a rack is slidably connected to the outer wall of the slide bar, the rack meshes with the gear, a movable frame is fixedly connected to the front side of the rack, a cylinder is fixedly installed on the top of the base, a motor is fixedly installed on the output shaft of the cylinder, a turntable is fixedly installed on the output shaft of the motor, a protrusion is fixedly connected to the side of the turntable, and the protrusion contacts the movable frame.

[0007] Preferably, the filter mechanism is internally fixedly connected to a partition, and the filter mechanism is provided with a storage box on its side.

[0008] Preferably, a side door is rotatably connected to the side of the filter mechanism, and a blower is fixedly installed on the upper part of the filter mechanism.

[0009] Preferably, the side of the filter screen is rotatably connected to a screw, which is threadedly connected to the side plate.

[0010] Preferably, the sides of the slide are arc-shaped, and the sides of the filter screen are arc-shaped.

[0011] Preferably, the top of the slide bar is fixedly connected to the adhesive filtering mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the rotation of an electric motor, a turntable, and a protrusion to move a movable frame up and down. A rack moves up and down along a slide bar, gears rotate back and forth, a rotating shaft rotates back and forth, a side plate rotates back and forth, and an internal filter screen rotates back and forth with a small amplitude. This movement of the filter screen improves the filtration effect of the rubber compound, preventing clogging by larger impurities. When impurities need to be removed from the filter screen, the intake of rubber compound is stopped. When only a small amount of rubber compound remains on the filter screen, the cylinder shortens, causing the internal filter screen to rotate at a larger angle, and the impurities fall into the storage box. In use, this device ensures thorough filtration of the rubber compound, minimizing waste. Attached Figure Description

[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 of the present utility model. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-6This utility model provides a technical solution: a rubber filtering device for rubber compounding, including a base 1 and a filtering mechanism 2. The filtering mechanism 2 has an inlet at the top and an outlet at the bottom. The base 1 and the filtering mechanism 2 are fixedly connected. A rotating shaft 304 is rotatably connected to the middle of the filtering mechanism 2. There are three rotating shafts 304, which are evenly distributed. A side plate 305 is fixedly connected to the side of the rotating shaft 304. The side plate 305 rotates with the rotating shaft 304. A slide rail 306 is fixedly connected to the side of the side plate 305. A filter screen 4 is slidably connected between the slide rails 306. There are three filter screens 4. The upper mesh is larger, the middle mesh is smaller, and the lower mesh is smaller, but the overall size is the same. A gear 303 is fixedly connected to the outer wall of the rotating shaft 304. The rotation of the gear 303 causes the rotating shaft 304 to rotate. A slide bar 3 is fixedly connected to the top of the base 1. There are two slide bars 3, which are parallel to each other. A rack 301 is slidably connected to the outer wall of the slide bar 3. The rack 301 can move up and down along the slide bar 3. The rack 301 meshes with the gear 303. The up and down movement of the rack 301 causes the gear 303 to rotate. A movable frame 30 is fixedly connected to the front of the rack 301. 2. The moving frame 302 and the rack 301 are a single unit and move up and down together. A cylinder 5 is fixedly installed on the top of the base 1. A motor 501 is fixedly installed on the output shaft of the cylinder 5. A turntable 502 is fixedly installed on the output shaft of the motor 501. A protrusion 503 is fixedly connected to the side of the turntable 502. The protrusion 503 and the output shaft of the motor 501 are not on the same straight line. The protrusion 503 contacts the moving frame 302. When the motor 501 rotates, the turntable 502 rotates, and the protrusion 503 rotates, causing the moving frame 302 to move up and down. The strip 301 moves up and down along the slide bar 3, the gear 303 rotates back and forth, the shaft 304 rotates back and forth, the side plate 305 rotates back and forth, and the internal filter screen 4 rotates back and forth with a small rotation amplitude. The movement of the filter screen 4 can make the filtration effect of the compound better and prevent it from being blocked by large impurities. When it is necessary to remove impurities from the filter screen 4, the intake of compound is stopped. When there is very little compound on the filter screen 4, the cylinder 5 shortens, causing the internal filter screen 4 to rotate at a larger angle, and the impurities fall into the storage box 203, and the storage box 203 is cleaned regularly.

[0023] The filter mechanism 2 is internally fixedly connected to a partition 204, which separates the interior to prevent impurities from falling into the storage box 203. The filter mechanism 2 is provided with a storage box 203 on its side, where impurities fall. The storage box 203 needs to be cleaned regularly.

[0024] The filter mechanism 2 is rotatably connected to a side door 201. Opening the side door 201 makes it easy to replace the filter screen 4 and facilitates maintenance. A blower 202 is fixedly installed on the upper part of the filter mechanism 2. The blower 202 blows air to accelerate the internal filtration.

[0025] The filter screen 4 is rotatably connected to a screw 401 on its side. The screw 401 is threadedly connected to the side plate 305. The filter screen 4 can be replaced by rotating the screw 401.

[0026] The slide 306 has a rounded side, and the filter screen 4 has a rounded side, allowing the filter screen 4 to slide smoothly into the slide 306, making it easy to use.

[0027] The top of the slide bar 3 is fixedly connected to the filter mechanism 2 to increase the stability of the slide bar 3.

[0028] Working principle: During use, the motor 501 rotates, the turntable 502 rotates, and the protrusion 503 rotates, causing the moving frame 302 to move up and down. The rack 301 moves up and down along the slide bar 3, the gear 303 rotates back and forth, the rotating shaft 304 rotates back and forth, the side plate 305 rotates back and forth, and the internal filter screen 4 rotates back and forth with a small rotation amplitude. The movement of the filter screen 4 can improve the filtration effect of the compound and prevent it from being blocked by large impurities. When it is necessary to remove impurities from the filter screen 4, the intake of compound is stopped. When there is very little compound on the filter screen 4, the cylinder 5 shortens, causing the internal filter screen 4 to rotate at a larger angle, and the impurities fall into the storage box 203. The storage box 203 is cleaned regularly.

[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 and modifications 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.
