Description

Technical Field

[0001] This utility model relates to the field of rubber production machinery technology, specifically to a mixing equipment for producing anti-adhesion polymer materials. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformations under small external forces. After the external force is removed, it can return to its original shape. Rubber is a completely amorphous polymer. Mixing equipment is rubber mixing equipment used to mix raw rubber and compounding agents. It can also plasticize natural rubber. Mixing methods are generally divided into two types: open mill mixing and internal mixer mixing. Both of these methods are batch mixing, which is currently the most widely used method.

[0003] During rubber production, raw materials are transferred to the inside of a mixing chamber. During transfer, the materials are stirred and mixed after entering the mixing chamber.

[0004] However, the raw materials are not stirred when they are transferred into the mixing box. The mixing by a single stirring rod is not uniform enough. After entering the mixing box, the materials are stirred by the stirring rod inside the mixing box, which easily leads to uneven mixing. In view of this, we propose a mixing equipment for the production of anti-adhesion polymer materials. Utility Model Content

[0005] The purpose of this invention is to provide a mixing equipment for producing anti-adhesion polymer materials, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing equipment for producing anti-adhesion polymer materials, comprising a mixing box, a cover plate fixedly connected to the top end face of the mixing box, a feed hopper fixedly connected to the top end face of the cover plate, a premixing component disposed inside the feed hopper, a discharge component disposed outside the outer wall of the feed hopper, the premixing component comprising a mixing chamber fixedly connected to the inner wall of the feed hopper, a servo motor fixedly connected to the outer wall of the feed hopper, a rotating shaft fixedly connected to the output end of the servo motor, a scraper fixedly connected to the side wall of the rotating shaft, a baffle slidably connected to the inner wall of the mixing chamber, and a rubber rod fixedly connected to the side wall of the baffle.

[0007] Preferably, a drive motor is fixedly connected to the side wall of the mixing box, and a stirring rod is fixedly connected to the output end of the drive motor. The stirring rod thoroughly mixes the raw materials in the mixing box.

[0008] Preferably, the side walls of the mixing chamber, feed hopper, rotating shaft, scraper, baffle, and baffle bar are coated with Teflon. The connection between the scraper and the rotating shaft is provided with an arc-shaped chamfer, and the connection between the baffle bar and the rotating shaft is provided with an arc-shaped chamfer. The Teflon coating and the arc-shaped chamfer reduce the adhesion of raw materials.

[0009] Preferably, the unloading assembly includes a rotating rod rotatably connected to the side wall of the feed hopper, a driving gear fixedly connected to the side wall of the rotating rod, a fixed frame fixedly connected to the side wall of the feed hopper, a driven gear rotatably connected to the inner wall of the fixed frame, a reciprocating screw fixedly connected to the end face of the driven gear, a moving frame drivingly connected to the side wall of the reciprocating screw, a rotating rod fixedly connected to the end face of the reciprocating screw, a deflecting rod slidably connected to the side wall of the rotating rod, a connecting rod fixedly connected to the side wall of the deflecting rod, and a slidably connected to the moving frame. The deflecting rod deflects the rubber rod, driving the baffle to open, thereby allowing the premixed raw materials to fall into the mixing box.

[0010] Preferably, a limiting frame is fixedly connected to the side wall of the feed hopper, and the movable frame is movably connected to the inner wall of the limiting frame, so that the limiting frame can only move laterally back and forth.

[0011] Preferably, the driving gear and the driven gear are connected by a transmission, and a pulley is fixedly connected to the side wall of the rotating shaft and the rotating rod. The pulley is connected to a belt for transmission. Through the transmission of the belt, the forward rotation of the rotating shaft drives the rotating rod to rotate in the forward direction. The forward rotation of the rotating rod drives the reciprocating screw and the rotating rod to rotate in the reverse direction through the transmission of the driving gear and the driven gear.

[0012] Preferably, the actuating rod is movably connected to the rubber rod, and the connecting rod is rotatably connected to the movable frame. The connecting rod allows the actuating rod to rotate with the rotating rod while also being pulled by the movable frame to move linearly along the axis of the rotating rod.

[0013] Preferably, a rubber plate is fixedly connected to the side wall of the rotating shaft, and a toothed ring is fixedly connected to the side wall of the feed hopper. The rubber plate and the toothed ring are movably connected. The rotation of the rotating shaft causes the rubber plate to continuously strike the outer wall of the toothed ring, thereby transmitting the vibration to the feed hopper and promoting the premixing and feeding of the raw materials.

[0014] Compared with the prior art, this utility model provides a mixing equipment for producing anti-adhesion polymer materials, which has the following beneficial effects: 1. This anti-adhesion polymer material production mixing equipment, through its premixing components, promotes the initial dispersion and uniform mixing of raw materials before they enter the mixing chamber. This premixing process ensures that the raw materials undergo initial tumbling and dispersion before entering the mixing chamber, preventing them from entering in an agglomerated state. This improves the subsequent mixing effect from the source and enhances the consistency of finished product quality. The Teflon coating on the surfaces of components in direct contact with the raw materials reduces the surface energy and coefficient of friction, making it difficult for high-viscosity polymer materials to adhere to the structural surface, thereby reducing wall adhesion, clumping, and residue. The unloading components enable automatic coordination of premixing, agitation, plate opening, and unloading actions, allowing for rhythmic unloading without the need for an additional control system, thus improving the stability and automation of equipment operation.

[0015] 2. This anti-adhesion polymer material production mixing equipment, through the setting of rubber plates and toothed rings, causes the feed hopper to generate continuous micro-vibration during operation, which promotes the loosening and sliding of raw materials. Thus, without adding an additional power source, it assists the pre-mixing process of raw materials in the feed hopper and promotes the smooth discharge of raw materials. Attached Figure Description

[0018] like Figures 1-7As shown, this utility model provides a technical solution: a mixing equipment for producing anti-adhesion polymer materials, including a mixing box 1, a cover plate 2 fixedly connected to the top end face of the mixing box 1, a feed hopper 3 fixedly connected to the top end face of the cover plate 2, a premixing component 5 disposed inside the feed hopper 3, and a discharge component 6 disposed outside the outer wall of the feed hopper 3. The premixing component 5 includes a mixing chamber 501 fixedly connected to the inner wall of the feed hopper 3, a servo motor 502 fixedly connected to the outer wall of the feed hopper 3, a rotating shaft 503 fixedly connected to the output end of the servo motor 502, a scraper 504 fixedly connected to the side wall of the rotating shaft 503, a baffle 505 fixedly connected to the side wall of the rotating shaft 503, a baffle 506 slidably connected to the inner wall of the mixing chamber 501, and a rubber rod 507 fixedly connected to the side wall of the baffle 506.

[0019] In one embodiment of this utility model, a drive motor 4 is fixedly connected to the side wall of the mixing box 1, and a stirring rod 10 is fixedly connected to the output end of the drive motor 4. The stirring rod 10 fully mixes the raw materials in the mixing box 1. The side walls of the mixing chamber 501, the feed hopper 3, the rotating shaft 503, the scraper 504, the baffle 506, and the baffle rod 505 are provided with Teflon coating. The connection between the scraper 504 and the rotating shaft 503 is provided with an arc-shaped chamfer, and the connection between the baffle rod 505 and the rotating shaft 503 is provided with an arc-shaped chamfer. The Teflon coating and the arc-shaped chamfer reduce the adhesion of the raw materials.

[0020] The unloading assembly 6 includes a rotating rod 601 rotatably connected to the side wall of the feed hopper 3. A drive gear 602 is fixedly connected to the side wall of the rotating rod 601. A fixed frame 603 is fixedly connected to the side wall of the feed hopper 3. A driven gear 604 is rotatably connected to the inner wall of the fixed frame 603. A reciprocating screw 605 is fixedly connected to the end face of the driven gear 604. A moving frame 606 is drivenly connected to the side wall of the reciprocating screw 605. A rotating rod 608 is fixedly connected to the end face of the reciprocating screw 605. A toggle lever 609 is slidably connected to the side wall, and a connecting rod 610 is fixedly connected to the side wall of the toggle lever 609. The connecting rod 610 is slidably connected to the moving frame 606. The toggle lever 609 actuates the rubber rod 507, which drives the baffle 506 to open, allowing the premixed raw materials to fall into the mixing box 1. A limit frame 7 is fixedly connected to the side wall of the feed hopper 3. The moving frame 606 is movably connected to the inner wall of the limit frame 7. The limit frame 7 allows the moving frame 606 to only move laterally back and forth.

[0021] The driving gear 602 is connected to the driven gear 604. The rotating shaft 503 is fixedly connected to the side wall of the rotating rod 601 by a pulley. The pulley is connected to the belt 607. Through the transmission of the belt 607, the forward rotation of the rotating shaft 503 drives the rotating rod 601 to rotate in the forward direction. The forward rotation of the rotating rod 601 drives the reciprocating screw 605 and the rotating rod 608 to rotate in the reverse direction through the transmission of the driving gear 602 and the driven gear 604. The actuating rod 609 is movably connected to the rubber rod 507. The connecting rod 610 is rotatably connected to the moving frame 606. Through the connecting rod 610, the actuating rod 609 rotates with the rotating rod 608 and is also pulled by the moving frame 606 to move linearly along the axis of the rotating rod 608.

[0022] In use, the polymer material to be mixed is put into the feed hopper 3, and the servo motor 502 is started. The output end of the servo motor 502 drives the rotating shaft 503 to rotate around its own axis. At the same time as the rotating shaft 503 rotates, the scraper 504 and the baffle rod 505 fixedly connected to its side wall rotate synchronously. When the scraper 504 rotates in the mixing chamber 501, it drives and pushes the raw material along the inner wall of the mixing chamber 501, so that the raw material generates circumferential movement inside the mixing chamber 501. At the same time, the baffle rod 505 creates a disturbance effect on the raw material during the rotation, causing the raw material to roll up and down and move radially in the mixing chamber 501. This promotes the initial dispersion and uniform mixing of the raw material before it enters the mixing box 1, completing the premixing process. This ensures that the raw material completes the initial rolling and dispersion before entering the mixing box 1, avoiding the raw material entering the mixing box 1 in an agglomerated state, improving the subsequent mixing effect from the source, and improving the consistency of the finished product quality.

[0023] During the continuous rotation of the rotating shaft 503, the forward rotation of the rotating shaft 503 synchronously drives the rotating rod 601 to rotate in the forward direction through the transmission action of the belt 607. After the rotating rod 601 rotates, through the meshing transmission of the driving gear 602 and the driven gear 604, the driven gear 604 drives the reciprocating screw 605 and the rotating rod 608 to rotate in the opposite direction. When the reciprocating screw 605 rotates, it drives the moving frame 606, which is connected to it, to reciprocate linearly only in the horizontal direction under the constraint of the limiting frame 7. At the same time, during the rotation of the rotating rod 608, through the sliding connection of the actuating rod 609, the actuating rod 609 rotates with the rotating rod 608 and, under the traction action of the connecting rod 610 and the moving frame 606, generates a synchronous linear displacement along the axial direction of the rotating rod 608. When the actuating rod 609 moves close to the feed hopper 3... When in the lateral position, the actuating lever 609 contacts the rubber rod 507 and generates a actuating action. After being subjected to force, the rubber rod 507 pushes the baffle 506 to slide along the inner wall of the mixing chamber 501, causing the baffle 506 to open. The premixed raw materials fall into the mixing box 1 through the lower opening of the mixing chamber 501 under the action of gravity, completing the feeding process. When the baffle 506 moves to the top, the baffle 506 is blocked by the inner wall of the feed hopper 3. At this time, the actuating action of the actuating lever 609 causes the rubber rod 507 to deform. The rubber rod 507 and the actuating lever 609 lose their pushing action. At this time, the baffle 506 automatically resets under the action of gravity, and covers the feeding channel at the bottom of the mixing chamber 501 again. This realizes the automatic coordination of premixing, actuating, opening and feeding actions, and completes the cycle feeding without the need for an additional control system, improving the stability and automation of equipment operation.

[0024] The sliding feeding direction of the baffle 506 is set to be opposite to the rotation direction of the rotating shaft 503, so that during the rotation of the scraper 504, the movement trend of the raw material is away from the fit gap between the baffle 506 and the mixing chamber 501, thus preventing the raw material from being squeezed into the gap between the baffle 506 and the mixing chamber 501 from both structural and movement directions.

[0025] By applying a Teflon coating to the surfaces of components that directly contact the raw materials, such as the feed hopper 3, mixing chamber 501, rotating shaft 503, scraper 504, baffle bar 505, and baffle 506, the surface energy and coefficient of friction of the contact surfaces are reduced, making it difficult for high-viscosity polymer raw materials to adhere to the structural surfaces, thereby reducing wall adhesion, clumping, and residue. Furthermore, the connection points between the scraper 504 and the rotating shaft 503, and between the baffle bar 505 and the rotating shaft 503, are designed with rounded chamfers to avoid forming right angles or sharp corners, reducing the possibility of raw material accumulation and retention at the connection points. This structurally eliminates areas prone to adhesion, improving cleanliness and operational stability.

[0026] In addition, a rubber plate 8 is fixedly connected to the side wall of the rotating shaft 503, and a toothed ring 9 is fixedly connected to the side wall of the feed hopper 3. The rubber plate 8 and the toothed ring 9 are movably connected. During the operation of the equipment, the servo motor 502 drives the rotating shaft 503 to rotate continuously around its own axis. As the rotating shaft 503 rotates, the rubber plate 8 fixedly connected to the side wall of the rotating shaft 503 moves in a circular motion. When the rotating shaft 503 rotates, the rubber plate 8 periodically knocks against the outer wall of the toothed ring 9 on the motion trajectory. After the rubber plate 8 undergoes elastic deformation, it quickly recovers and knocks against the toothed ring 9 again. Through the above periodic knocking process, the mechanical vibration generated by the rubber plate 8 is transmitted to the toothed ring 9 and further to the overall structure of the feed hopper 3, so that the feed hopper 3 generates continuous micro-vibration during operation. This vibration keeps the raw material in the feed hopper 3 in a non-static state, causing the raw material to loosen and slide, thereby assisting the pre-mixing process of the raw material in the feed hopper 3 without adding an additional power source, and promoting the smooth discharge of the raw material.

[0027] In this invention, during use, the polymer material to be mixed is put into the feed hopper 3, the servo motor 502 is started, the servo motor 502 drives the rotating shaft 503 to rotate, the rotating shaft 503 drives the scraper 504 and the baffle rod 505 to rotate synchronously in the mixing chamber 501, tumbling and agitating the raw material to achieve premixing. The rotating shaft 503 drives the rotating rod 601 to rotate through the belt 607, and through the drive gear 602 and the driven gear 604, the reciprocating screw 605 and the rotating rod 608 rotate, the moving frame 606 reciprocates in the limiting frame 7, the actuating rod 609 actuates the rubber rod 507, and pushes the baffle 506 to open, so that the premixed raw material falls into the mixing box 1, and then the baffle 506 resets under the action of gravity.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
