Description

Technical Field

[0001] The utility model relates to the technical field of kneaders, and more specifically to a kneader for producing mixed silicone rubber. Background Art

[0002] Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and the silicon atoms are usually connected to two organic groups. The kneader is a mixing and stirring equipment that can be used to knead, mix, vulcanize and polymerize high-viscosity, elastic-plastic materials such as silicone rubber and sealants. The most commonly used is two "Σ" blades, one with a fast stirring paddle and the other with a slow stirring paddle, in order to generate shear force, so that the semi-dry materials and the raw materials react quickly to obtain uniform mixing and stirring.

[0003] Existing kneaders for compounding silicone rubber require the regular addition of different raw materials during use. The current method of adding materials is usually to open the cover and manually pour the raw materials in. As a result, the temperature in the kneader is lost during the pouring process, reducing the efficiency of mixing and fusion.

[0004] At the same time, during the process of pouring raw materials, powdery materials are easy to escape, resulting in the air quality in the working environment being affected. In view of this, we propose a kneading machine for the production of compounded silicone rubber. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a kneader for the production of mixed silicone rubber to solve the current problem of temperature loss in the kneader during the pouring operation, which reduces the efficiency of stirring and fusion. At the same time, during the process of pouring raw materials, powdery materials are easily dispersed, resulting in the technical problem of affecting the air quality in the working environment.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a kneader for producing mixed silicone rubber, comprising a kneader main body, a top surface of a stirring portion on the kneader main body being provided with a cover plate, and a slidable material storage member being provided on the top of the cover plate;

[0007] The cover plate wall is provided with a material discharge port, and the top of the cover plate and both sides of the front and rear sides of the material discharge port are fixed with limit plates, and the two limit plates are provided with arc-shaped limit grooves on the sides facing each other;

[0008] The material storage part includes a loading box that is fitted with the two limiting plates on the opposite sides. A number of storage cavities are opened between the upper and lower sides of the loading box. A sliding cover is slidably installed on the top of the storage cavity. The front and rear sides of the loading box are integrally constructed with limiting slides combined with the limiting plates. A scraper corresponding to the opening of the storage cavity on the left side is fixed on the top of the cover plate.

[0009] The utility model can store a variety of different raw materials in partitions by arranging a storage structure on the top of the cover plate, and can limit the installation position of the charging box by arranging two limit plates. At the same time, the charging box can be conveniently slid laterally on the top of the cover plate with the cooperation of the limit groove and the limit slide bar, so that the lower opening of the storage cavity at different positions is aligned with the position of the discharge port, so that the raw materials stored in the storage cavity can be poured into the interior of the stirring part through the position of the discharge port in turn. Such structural cooperation can eliminate the step of opening the cover to add materials, and the sliding cover arranged on the top of the charging box can maintain a sealed state, which is not easy to reduce the temperature during the feeding process, and also reduces the probability of dust dispersion, thereby effectively improving the quality of the mixed silicone rubber production.

[0010] Preferably, the scraper member includes an L-shaped plate, an adjustment plate is installed on the top of the L-shaped plate, a second electric push rod is installed at the position where the adjustment plate is aligned with the left storage cavity, and the telescopic end of the second electric push rod is fixed with a scraper plate with the same shape as the storage cavity.

[0011] Preferably, a limiting round rod passing through the adjustment plate is fixed on the top of the L-shaped plate, a limiting round plate in contact with the top surface of the adjustment plate is fixed on the top of the limiting round rod, and a pin is inserted and connected between the adjustment plate and the limiting round plate.

[0012] Preferably, the corners of the material storage cavity are in the shape of arc corners, and the corners of the scraper plate are in the same shape as the corners of the material storage cavity.

[0013] Preferably, a first electric push rod is fixedly provided on the top of the cover plate and on the outer sides of the two discharge ports, and a connecting plate fixedly connected to the first electric push rod is fixedly provided on both sides of the loading box.

[0014] Preferably, the front and rear sides of the charging box are both provided with sliding grooves, and both side edges of the sliding cover are integrally constructed with clips combined with the sliding grooves.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model can store a variety of different raw materials in partitions by arranging a storage structure on the top of the cover plate, and can limit the installation position of the charging box by setting two limit plates. At the same time, with the cooperation of the limit groove and the limit slide bar, the charging box can be conveniently slid horizontally on the top of the cover plate, so that the lower opening of the storage cavity at different positions is aligned with the position of the discharge port, so that the raw materials stored in the storage cavity can be poured into the interior of the stirring part through the position of the discharge port in turn. Such structural cooperation can eliminate the step of opening the cover to add materials. The sliding cover arranged on the top of the charging box can maintain a sealed state, and it is not easy to reduce the temperature during the adding process. At the same time, it also reduces the probability of dust dispersion, thereby effectively improving the quality of the mixed silicone rubber production.

[0017] 2. The scraper design of the utility model can move downward to the corresponding position of the storage chamber when adding raw materials during use through the cooperation of the second electric push rod and the scraper plate. This can scrape off the raw materials adhering to the inner wall of the storage chamber, reduce the residual rate of raw material adhesion, and enhance the accuracy of raw material addition. At the same time, the downward movement of the scraper plate can also seal the discharge port, further improving the sealing effect. The storage part can achieve the effect of automatic displacement under the action of the first electric push rod, so that the storage chambers at different positions automatically move to the position of the discharge port, achieving the effect of automatic discharge, and further improving the flexibility of structural coordination.

[0024] A feeding port 102 is provided on the wall of the cover plate 101, and limiting plates 103 are fixed on the top of the cover plate 101 and on both sides of the front and rear sides of the feeding port 102. The two limiting plates 103 have arc-shaped limiting grooves 104 on the facing sides. The design of the feeding port 102 facilitates the addition of raw materials to the interior of the stirring part, and the cooperation between the limiting plates 103 and the limiting grooves 104 is used to limit the installation position of the storage part 2.

[0025] The storage member 2 includes a loading box 201 that is fitted with the two side limit plates 103 facing each other. A plurality of storage cavities 202 are provided between the upper and lower sides of the loading box 201. A sliding cover 204 is slidably installed on the top of the storage cavity 202. The front and rear sides of the loading box 201 are integrally constructed with a limiting slide 205 combined with the limiting plate 103. A scraper 4 corresponding to the opening of the storage cavity 202 on the left side is fixed on the top of the cover plate 101; a limiting groove is provided on the limiting plate 103. The combination of 104 and the limiting slide 205 can limit the installation position of the charging box 201, and at the same time make the charging box 201 slide against the top of the cover 101, so that the storage chamber 202 at different positions can be moved above the discharge port 102, so that the raw materials stored in the storage chamber 202 can automatically fall into the interior of the stirring part along the discharge port 102. The sealing of the sliding cover 204 can prevent the temperature from being lost during the feeding process, and can also prevent dust from being dispersed.

[0026] In an embodiment of the present utility model, the scraper 4 includes an L-shaped plate 401, an adjustment plate 402 is installed on the top of the L-shaped plate 401, and a second electric push rod 406 is installed at the position where the adjustment plate 402 is aligned with the left storage chamber 202, and the telescopic end of the second electric push rod 406 is fixed with a scraper plate 407 with the same shape as the storage chamber 202; with the support of the L-shaped plate 401 and the adjustment plate 402, the scraper plate 407 at the bottom of the second electric push rod 406 can be set above the storage chamber 202, and the same shape can facilitate the scraper plate 407 to move to the inside of the storage chamber 202, so that the raw materials adhering to the inner wall of the storage chamber 202 can be scraped off during the downward movement, thereby reducing the residual raw materials.

[0027] In an embodiment of the present utility model, a limiting circular rod 403 passing through the adjusting plate 402 is fixed on the top of the L-shaped plate 401, a limiting circular plate 404 fitted with the top surface of the adjusting plate 402 is fixed on the top of the limiting circular rod 403, and a latch 405 is inserted and connected between the adjusting plate 402 and the limiting circular plate 404; through the cooperation, the position of the scraper plate 407 can be conveniently rotated and adjusted without affecting the disassembly and assembly operation of the loading box 201.

[0028] In an embodiment of the present invention, the corner shape of the storage chamber 202 is a circular arc corner 203, and the corner shape of the scraper plate 407 is the same as the corner shape of the storage chamber 202; the design of the circular arc corner 203 can reduce the adhesion dead angle and increase the contact surface between the storage chamber 202 and the scraper plate 407.

[0029] In an embodiment of the present utility model, a first electric push rod 3 is fixedly provided on the top of the cover plate 101 and on the outer sides of the two discharge ports 102, and a connecting plate 208 fixedly connected to the first electric push rod 3 is fixedly provided on both sides of the loading box 201; the first electric push rod 3 is connected to the connecting plate 208 on the loading box 201 to push the loading box 201 to move, so that the effect of automatic unloading can be achieved.

[0030] In an embodiment of the present invention, a slide groove 206 is provided on the front and rear sides of the loading box 201, and both side edges of the sliding cover 204 are integrally constructed with a clamping strip 207 combined with the slide groove 206; the combination of the slide groove 206 and the clamping strip 207 can fix the position of the sliding cover 204 so that it can only slide horizontally, thereby improving the stability of the connection.

[0031] Working principle: This embodiment provides a kneading machine for the production of compounded silicone rubber. When in use, first remove the sliding cover 204 on the top of the charging box 201 to expose the opening of the storage chamber 202. In this way, different raw materials can be added to the storage chamber 202 at different positions in turn. After completion, the card strips 207 on both sides of the sliding cover 204 can be inserted into the slide grooves 206 on both sides of the charging box 201, and the opening of the storage chamber 202 can be closed by sliding to seal the raw materials inside. In this way, when raw materials need to be added during the operation of the stirring part on the kneading machine body 1, the first electric push rod 3 can be started. The operation of the first electric push rod 3 pushes the charging box 201 forward, so that the storage chamber 202 filled with raw materials moves to the position of the limit plate 103. The connection between the two can make the raw materials automatically fall into the stirring chamber. The interior of the mixing section achieves the effect of automatic feeding. When the loading box 201 moves, the scraper plate 407 at the side end of the scraper 4 will limit the synchronous movement of the sliding cover 204, so that the opening of the storage chamber 202 on the left side moves to the bottom of the scraper plate 407. When the storage chamber 202 filled with raw materials is aligned with the limit plate 103, the scraper plate 407 is aligned with the storage chamber 202. In this way, the scraper plate 407 can be controlled to move down into the storage chamber 202 under the operation of the second electric push rod 406, so that the raw materials adhering to the inner wall of the storage chamber 202 can be squeezed down to the inside of the mixing section, reducing raw material residue and improving the accuracy of raw material addition. The overall structural coordination can reduce temperature loss during the feeding process, and at the same time reduce the probability of dust dispersion, thereby improving production quality.
