[0002] An internal mixer is a machine that is provided with a pair of rotors with specific shapes and rotating relatively, and intermittently plasticizes and kneads polymer materials in a closed state with adjustable temperature and pressure. According to different discharging methods, internal mixers can be divided into tipping type and opening and closing type. Among them, there is a 0.2L small opening and closing type internal mixer, which is mainly used for formula research and development, raw material tests, etc. in the laboratory. It has a small body, less material consumption, simple operation, and is equipped with a dust prevention device itself, thus preventing the laboratory environment from being polluted when the internal mixer is working.

[0003] This internal mixer mainly includes a fixed plate, a roller rotatably arranged on the fixed plate, a bin body plate detachably arranged on the fixed plate by bolts, and a feed hopper arranged above the bin body plate. When in use, rubber material can be poured into the bin body plate from the feed hopper, and then the bin body plate is heated. During this process, it is gradually liquefied into a gel state by the agitation of the roller. Then, the bolts on the bin body plate are unscrewed to remove the bin body plate, and the operator manually removes the gel on the roller with tools.

[0004] It is found in actual operation that the bin body plate is fixed on the fixed plate by bolts. Therefore, when taking materials, the bin body plate needs to be removed, and the operation process is very laborious. Moreover, the operator is easily scalded by the residual temperature of the bin body plate during the process of manually removing the bin body plate. Content of the Utility Model

[0005] In order to solve the above technical problems, an internal mixer for preventing dust is provided, which solves the problems in the prior art that the bin body plate is fixed on the fixed plate by bolts, resulting in the need to remove the bin body plate when taking materials, the operation process is very laborious, and the operator is easily scalded by the residual temperature of the bin body plate during the process of manually removing the bin body plate.

[0006] To achieve the above object, the technical solution adopted by the utility model is: an internal mixer for preventing dust, including a bottom plate, a fixed plate fixed on the top surface of the bottom plate, and a bin body plate slidably arranged on one side of the fixed plate. Two rollers are arranged on one side of the fixed plate facing the bin body plate, and two motors are arranged on the side of the fixed plate away from the bin body plate. The two motors correspond to the two rollers one by one. The output shaft of the motor rotates through the fixed plate and is fixed to the roller. An elliptical groove is formed on the side of the bin body plate facing the fixed plate, and the roller slidably penetrates into the groove. A feed hopper communicated with the groove of the bin body plate is fixed on the top surface of the bin body plate. Its characteristic lies in that: convenient disassembly mechanisms are arranged at both ends of the bin body plate;

[0007] The convenient splitting mechanism includes a screw rod arranged on the outer side of the bin body plate, a first fixing block fixed on the end face of the fixing plate, and a second fixing block threadedly sleeved on the rod body of the screw rod. The second fixing block is fixed on the side wall of the bin body plate. One end of the screw rod is rotatably connected to the first fixing block. A support plate vertically fixed to the top surface of the bottom plate is arranged on the side of the bin body plate away from the fixing plate. A material pushing component is arranged in the groove of the bin body plate.

[0008] Preferably, the material pushing component includes a sliding shaft horizontally arranged in the groove. One end of the sliding shaft sequentially slides through the groove of the bin body plate and the support plate. A pushing block fitted with the groove is fixed to the other end of the sliding shaft.

[0009] Preferably, the material pushing component further includes a fixing ring arranged between the bin body plate and the support plate. The fixing ring is fixedly sleeved on the rod body of the sliding shaft.

[0010] Preferably, the other ends of the two screw rods both rotatably penetrate through the support plate and are fixedly sleeved with belt pulleys. A belt is drivingly connected between the two belt pulleys. A handle is fixed to the side of one of the belt pulleys away from the support plate.

[0011] Compared with the prior art, the advantages of the present utility model are as follows:

[0012] (1) Through the setting of the convenient splitting mechanism, after the material is stirred into a gelatinous state, the handle is rotated to drive one of the belt pulleys to rotate. The rotation of one of the belt pulleys drives the other belt pulley to rotate synchronously through the transmission belt. The rotation of the two belt pulleys drives the rotation of the two screw rods. The rotation of the two screw rods drives the movement of the two second fixing blocks. The movement of the second fixing blocks drives the bin body plate to move away from the fixing plate. As the bin body plate moves away, the roller on the fixing plate disengages from the groove of the bin body plate. Subsequently, the rubber on the roller is shoveled off by a shovel manually. In this way, the problem in the prior art that the bin body plate is fixed to the fixing plate by bolts, resulting in the necessity of disassembling the bin body plate when taking materials, the operation process is laborious and the operator is easily scalded by the residual temperature of the bin body plate during the process of disassembling the bin body plate by hand can be solved.

[0013] (2) By setting the lifting component, when separating the bin plate from the fixed plate, the sliding shaft can be manually held, and then the pulley is rotated to separate the bin plate from the fixed plate. During this process, the rubber on the roller is pressed by the push block until the bin plate groove is completely separated from the roller. The rubber in the bin plate groove is pushed out by the push block, and then the sliding shaft is manually released and the pulley is continuously rotated. As the bin plate and the fixed ring are pressed against each other, the sliding shaft is driven to move synchronously by pushing the fixed ring. The movement of the sliding shaft drives the push block to move toward the end away from the roller. As the push block and the roller are separated, the rubber on one side of the roller and the push block is shoveled off by a shovel. In this way, the problem that part of the rubber is stuck in the bin plate groove due to the adhesion characteristics of the rubber, making it inconvenient for the operator to remove it can be solved.

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] Reference Figure 1 , Figure 2 and Figure 3 As shown, a dust-proof internal mixer comprises a bottom plate 1, a fixed plate 2 fixed to the top surface of the bottom plate 1, and a bin plate 3 slidably arranged on one side of the fixed plate 2, two rollers 7 are arranged on the side of the fixed plate 2 facing the bin plate 3, two motors 6 are arranged on the side of the fixed plate 2 away from the bin plate 3, the two motors 6 correspond to the two rollers 7 one by one, the output shafts of the motors 6 rotate and penetrate the fixed plate 2 and are fixed to the rollers 7, an elliptical groove is provided on the side of the bin plate 3 facing the fixed plate 2, the rollers 7 slide into the groove, a feed hopper 12 connected to the groove of the bin plate 3 is fixed on the top surface of the bin plate 3, and convenient splitting mechanisms are arranged at both ends of the bin plate 3;

[0021] The convenient splitting mechanism includes a screw rod 8 rotatably arranged at the end of the bin body plate 3, a first fixed block 10 fixed at the end of the fixed plate 2, and a second fixed block 13 threadedly sleeved on the rod body of the screw rod 8. The second fixed block 13 is fixed on the side wall of the bin body plate 3. One end of the screw rod 8 is rotatably connected to the first fixed block 10. On the side of the bin body plate 3 away from the fixed plate 2, there is a support plate 4 vertically fixed to the top surface of the bottom plate 1. The other ends of the two screw rods 8 both rotatably penetrate through the support plate 4 and are fixedly sleeved with belt pulleys. A belt is drivingly connected between the two belt pulleys. On the side of one of the belt pulleys away from the support plate 4, there is a handle fixed;

[0022] Through the setting of the convenient splitting mechanism, when rubber mixing is required, materials can be poured from the feed hopper 12, and then the bin body plate 3 is heated. At the same time, two motors 6 are respectively started, one motor 6 rotates forward and one motor 6 rotates backward. The two rollers 7 are driven by the two motors 6 to rotate forward and backward respectively. After the materials melt in the grooves of the bin body plate 3, the two rollers 7 stir the melted materials. After the materials are stirred into a gel state, the handle is rotated to drive one of the belt pulleys to rotate. The rotation of one of the belt pulleys drives the other belt pulley to rotate synchronously through the transmission belt. The rotation of the two belt pulleys drives the rotation of the two screw rods 8. The rotation of the two screw rods 8 drives the movement of the two second fixed blocks 13. The movement of the second fixed blocks 13 drives the bin body plate 3 to move away from the fixed plate 2. As the bin body plate 3 moves away, the rollers 7 on the fixed plate 2 disengage from the grooves of the bin body plate 3. Subsequently, the operator shovels the rubber on the rollers 7 with a shovel. Similarly, after the rubber is taken away, the belt pulleys are reversed, and the two belt pulleys drive the two screw rods 8 to reverse, and then drive the bin body plate 3 to move toward the side close to the fixed plate 2 through the two second fixed blocks 13 until the bin body plate 3 is reattached to the fixed plate 2. At this time, the rollers 7 re-enter the grooves of the bin body plate 3. In this way, it can solve the problem in the prior art that the bin body plate 3 is fixed to the fixed plate 2 by bolts, resulting in the necessity to disassemble the bin body plate 3 when taking materials, the operation process is laborious, and the operator is easily scalded by the residual temperature of the bin body plate 3 during the process of disassembling the bin body plate 3 by hand.

[0023] However, in reality, after the bin body plate 3 is separated from the fixed plate 2, due to the adhesive property of the rubber, part of the rubber adheres to the grooves of the bin body plate 3, which is not convenient for the operator to take out.

[0024] In view of this, as shown in Figures 1 to 3 It is worth noting that a material ejecting component is arranged in the groove of the bin body plate 3;

[0025] The material ejecting component includes a sliding shaft 9 transversely arranged in the groove of the bin body plate 3, one end of the sliding shaft 9 slides through the groove of the bin body plate 3 and the support plate 4 in sequence, and the other end of the sliding shaft 9 is fixed with a push block 11 that fits in the groove, and also includes a fixing ring 5 arranged between the bin body plate 3 and the support plate 4, and the fixing ring 5 is fixedly sleeved on the rod of the sliding shaft 9;

[0026] By setting the ejecting component, when separating the bin body plate 3 from the fixed plate 2, the sliding shaft 9 can be manually held, and then the pulley is rotated to separate the bin body plate 3 from the fixed plate 2. During this process, the rubber on the roller 7 is resisted by the push block 11 until the groove of the bin body plate 3 is completely separated from the roller 7, and the rubber in the groove of the bin body plate 3 is pushed out by the push block 11, and then the sliding shaft 9 is manually loosened, and the pulley is continued to be rotated. As the bin body plate 3 resists against the fixed ring 5, the sliding shaft 9 is driven to move synchronously by pushing the fixed ring 5. The movement of the sliding shaft 9 drives the push block 11 to move toward the end away from the roller 7. As the push block 11 and the roller 7 is separated, and the rubber on one side of the roller 7 and the push block 11 is shoveled off by a shovel. Similarly, the warehouse plate 3 is driven to move toward the side close to the fixed plate 2 by the reverse pulley. After the warehouse plate 3 moves a certain distance, the bottom surface of the groove of the warehouse plate 3 abuts against the push block 11, and the warehouse plate 3 continues to move and drives the push block 11 to move synchronously. The movement of the push block 11 drives the sliding shaft 9 and the fixed ring 5 to move synchronously until the warehouse plate 3 is fitted with the fixed plate 2 and the push block 11 abuts against the roller 7. In this way, the problem that part of the rubber sticks to the groove of the warehouse plate 3 due to the adhesion characteristics of the rubber, which is inconvenient for the operator to take out, can be solved.
