Description

Technical Field

[0001] This utility model relates to the field of tire raw material processing technology, specifically a tire rubber raw material internal mixer. Background Technology

[0002] The raw materials for tire rubber are mainly natural rubber, supplemented with synthetic rubbers such as styrene-butadiene rubber and butadiene rubber to enhance performance, and compounding agents such as carbon black and sulfur are added to improve wear resistance and elasticity. The tire rubber compound is made into tire rubber material suitable for different working conditions through processes such as intensive mixing.

[0003] The internal mixer is the core equipment for processing tire rubber raw materials. It uses the strong shearing action between the rotor and the mixing chamber to uniformly mix rubber with compounding agents such as carbon black and sulfur.

[0004] After the tire rubber raw materials are mixed in an intensive mixing chamber, they need to be removed. Because rubber is sticky, some of it will remain on the inner wall of the mixing chamber when it is removed, making cleaning quite tedious.

[0005] Therefore, a tire rubber raw material internal mixer is proposed to address the above problems. Utility Model Content

[0008] Preferably, the ejection assembly includes multiple electric push rods; the electric push rods and the ejection assembly are fixedly connected; by adding electric push rods, the replacement sleeve can be lifted when it is removed from the mixing chamber, so that it can quickly leave the mixing chamber, thereby increasing the convenience of removing the replacement sleeve.

[0009] Preferably, a magnet is fixed to the bottom of the insert block; the magnet and the insert block are correspondingly arranged; the mounting block is made of metal; by adding a magnet, after the insert block enters the mounting block, the magnetic force of the magnet will first attract the mounting block, so that the bolts can fix the insert block.

[0010] Preferably, the bottom of the replacement sleeve is fixedly connected with multiple connecting pipes; the connecting pipes and the mixing chamber are in a sliding fit; by adding connecting pipes, the heat generated when the rubber is stirred inside the replacement sleeve can be transferred to the outside, allowing it to be passively dissipated through the outside airflow, thereby treating the heat inside the replacement sleeve.

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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a tire rubber raw material internal mixer includes a base 1, a hydraulic cylinder 11 fixedly connected to the top of the base 1; a mixing chamber 12 fixedly connected to the top of the hydraulic cylinder 11; multiple ejection components 13 are arranged inside the mixing chamber 12; an installation block 14 is fixedly connected to the top of the ejection component 13; a replacement sleeve 16 is slidably fitted inside the mixing chamber 12; multiple insertion blocks 17 are fixedly connected to the side wall of the replacement sleeve 16; the insertion blocks 17 and the installation block 14 are connected by multiple bolts 15; a vertical plate 105 is fixedly connected to the surface of the base 1; a fixing plate 18 is fixedly connected to the top of the vertical plate 105; the fixing plate 18... A cylinder 19 is fixedly connected to the top of the 8th plate; a pressure chamber 101 is fixedly connected to the output end of the cylinder 19; the pressure chamber 101 and the replacement sleeve 16 are correspondingly arranged and slidably fitted; a motor 102 is fixedly connected to the inner wall of the upright plate 105; a drive gear 103 is fixedly connected to the output end of the motor 102; the drive gear 103 is rotatably connected to the upright plate 105; a driven gear 104 is rotatably connected to the middle of the upright plate 105; the drive gear 103 and the driven gear 104 are correspondingly arranged and are in a transmission fit; a rotor 106 is fixedly connected to the side wall of both the drive gear 103 and the driven gear 104; the rotor 106 is on the upright plate 105. Rotary connection; During operation, the insert block 17 is first inserted into the mounting block 14 and then fixed with bolts 15. After fixing, the hydraulic cylinder 11 is started to move the mixing chamber 12 upward. When it moves to the position of the rotor 106, it stops and the rotor 106 is contained inside the replacement sleeve 16. At this time, the raw material is placed inside the replacement sleeve 16. After placement, the motor 102 is started to drive the drive gear 103 to drive the driven gear 104 to rotate, thereby making the pair of rotors 106 rotate in opposite directions. During rotation, the raw material is stirred. Then, the cylinder 19 is started to move the pressurization chamber 101 into the replacement sleeve. 16 closes the replacement sleeve 16, and then the raw material is mixed. After the processing is completed, the mixing chamber 12 is restored. At this time, the raw material is taken out and the replacement sleeve 16 can be raised through the ejector component 13. Then the inside of the replacement sleeve 16 is processed. If there is a lot of adhesion during the processing, the bolt 15 can be removed to remove the replacement sleeve 16 for cleaning, and then it can be reinstalled. By adding the replacement sleeve 16, the cleaning of the mixing chamber 12 can be increased by disassembling the replacement sleeve 16 after the raw material is processed. This increases the operating space when cleaning is needed, thereby speeding up the cleaning process and reducing the inconvenience of cleaning the mixing chamber 12.

[0026] like Figures 1 to 5As shown, the ejection assembly 13 includes multiple electric actuators 2; the electric actuators 2 and the ejection assembly 13 are fixedly connected; during operation, when it is necessary to lift the replacement sleeve 16, activating the electric actuators 2 can push the mounting block 14 to move the replacement sleeve 16 out of the mixing chamber 12, thereby speeding up the operation of the replacement sleeve 16; by adding electric actuators 2, the replacement sleeve 16 can be lifted when disassembling it, so that it can quickly leave the mixing chamber 12, thereby increasing the convenience of disassembling the replacement sleeve 16.

[0027] like Figure 5 As shown, a magnet 3 is fixedly attached to the bottom of the insert 17; the magnet 3 and the insert 17 are correspondingly arranged; the mounting block 14 is made of metal; during operation, when installing the replacement sleeve 16, the insert 17 needs to be inserted into the mounting block 14 first. At this time, the magnet 3 will magnetically attract the mounting block 14 when it comes into contact with it, thereby increasing the initial stability when the insert 17 is inserted into the mounting block 14; by adding the magnet 3, after the insert 17 enters the mounting block 14, the magnetic force of the magnet 3 will first attract the mounting block 14, so that the auxiliary bolt 15 can fix the insert 17.

[0028] like Figures 4 to 5 As shown, multiple connecting pipes 4 are fixedly connected to the bottom of the replacement sleeve 16; the connecting pipes 4 and the mixing chamber 12 are in sliding fit; during operation, when the rubber is stirred inside the replacement sleeve 16, it will rub against the rotor 106, which will generate frictional heat, causing the interior of the replacement sleeve 16 to heat up. When the temperature rises, it will be transferred to the connecting pipes 4, allowing it to gradually exchange heat with the outside, thereby dissipating heat; by adding connecting pipes 4, the heat generated when the rubber is stirred inside the replacement sleeve 16 can be transferred to the outside, allowing it to be passively dissipated through the outside airflow, thereby treating the heat inside the replacement sleeve 16.

[0029] like Figures 3 to 4 As shown, the mixing chamber 12 has heat dissipation fins 5 on its side wall; multiple heat dissipation fins 5 are arranged on the mixing chamber 12; during operation, when there is a large amount of heat inside the mixing chamber 12, multiple heat dissipation fins 5 can be connected to an air pump to transfer airflow through the heat dissipation fins 5 into the mixing chamber 12. When the airflow moves inside the mixing chamber 12, it will blow the internal airflow, causing it to come into contact with and carry away the heat transferred to the mixing chamber 12 by the replacement sleeve 16, and then be discharged through the top of the mixing chamber 12, thereby increasing active heat dissipation; by adding heat dissipation fins 5, when there is a lot of heat, the airflow entering through the heat dissipation fins 5 can be increased to accelerate the internal airflow speed, thereby speeding up the heat processing.

[0030] like Figures 4 to 5As shown, multiple scrapers 6 are fixedly connected to the bottom of the mixing chamber 12; the ends of the scrapers 6 are set with an inclined surface and are corresponding to the connecting pipe 4; during operation, when the replacement sleeve 16 needs to be disassembled, the connecting pipe 4 will be moved out from inside the scraper 6. When it is moved out, the scraper 6 will push the dust on the surface of the connecting pipe 4 to make it fall off; by adding scrapers 6, the connecting pipe 4 can be quickly cleaned by the inclined surface of the scraper 6 when it passes through the scraper 6, so that the dust attached to its surface can be removed, thereby quickly reducing the dust and debris on the surface of the connecting pipe 4.

[0031] Working principle: First, insert the insert block 17 into the mounting block 14 and then fix it with bolts 15. After fixing, start the hydraulic cylinder 11 to move the mixing chamber 12 upward. When it moves to the position of rotor 106, stop and include rotor 106 inside the replacement sleeve 16. At this time, place the raw material into the replacement sleeve 16. After placement, start the motor 102 to drive the drive gear 103 to drive the driven gear 104 to rotate, thereby rotating the pair of rotors 106 in opposite directions. During rotation, the raw material will be stirred. Then, the cylinder... 19 is activated to drive the pressurization chamber 101 into the replacement sleeve 16, closing the replacement sleeve 16. The raw material is then subjected to internal mixing. After processing, the mixing chamber 12 is restored. The raw material is then removed, and the replacement sleeve 16 can be raised using the ejector assembly 13 for further processing. If there is significant adhesion during processing, bolts 15 can be removed to detach the replacement sleeve 16 for cleaning, followed by reinstallation. When it is necessary to raise the replacement sleeve 16, the electric actuator 2 is activated to push the mounting block 14, causing the replacement sleeve 16 to leave the mixing chamber 12. Internally, this speeds up the operation of the replacement sleeve 16. When installing the replacement sleeve 16, the insert 17 needs to be inserted into the mounting block 14 first. At this time, the magnet 3 will magnetically attract the mounting block 14 when in contact with it, thus increasing initial stability when inserting the insert 17 into the mounting block 14. During stirring inside the replacement sleeve 16, the rubber will rub against the rotor 106, generating frictional heat that raises the temperature inside the replacement sleeve 16. This heat is transferred to the connecting pipe 4, allowing it to gradually exchange heat with the outside environment, thereby dissipating heat. Heat; when there is a lot of heat inside the mixing chamber 12, multiple heat dissipation fins 5 can be connected to an air pump to transfer airflow through the heat dissipation fins 5 into the mixing chamber 12. When the airflow moves inside the mixing chamber 12, it will blow the airflow inside, so that it will come into contact with and carry away the heat transferred from the replacement sleeve 16 to the mixing chamber 12, and then be discharged through the top of the mixing chamber 12, thereby increasing active heat dissipation; when it is necessary to remove the replacement sleeve 16, the connecting pipe 4 will be removed from the inside of the scraper 6. When it is removed, the scraper 6 will push the dust on the surface of the connecting pipe 4 to make it fall off.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
