Description

Technical Field

[0001] This utility model relates to the field of screw barrel processing technology, and in particular to a screw barrel grinding machine. Background Technology

[0002] A screw barrel is a cylindrical component with a spiral shape. During the plastic extrusion process, a rough inner surface can cause localized stagnation of the plastic melt inside the screw barrel, affecting the plasticizing effect and product quality. Therefore, a grinding machine is an essential piece of equipment in screw barrel production.

[0003] Existing screw barrels are 3-5 meters long and have a narrow internal diameter. There is no suitable equipment to move the grinding wire wheel inside the screw barrel. Furthermore, the wire wheel wears excessively over time, causing wear on the threaded post connecting it, which in turn affects the subsequent installation of the wire wheel. Therefore, a screw barrel grinding machine is needed. This machine uses a double-layer structure to increase the stability of the wire wheel structure, preventing damage to the threaded post and allowing for proper installation of the wire wheel. With the assistance of the drive assembly, the wire wheel can move smoothly horizontally for a certain distance. Utility Model Content

[0004] The purpose of this utility model is to provide a screw barrel grinder to solve the problems mentioned in the background art, where the existing screw barrels are 3-5 meters long and have a narrow internal diameter, and there is no corresponding equipment to move the grinding wire wheel into the inside of the screw barrel. Furthermore, the wire wheel will wear excessively during long-term use, causing the threaded post connecting the wire wheel to also wear, which in turn affects the subsequent normal installation of the wire wheel.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a screw barrel grinding machine, comprising:

[0007] The drive component, the connection component, and the adjustment component are located on one side of the drive component, and the adjustment component is located on top of one side of the drive component.

[0008] The connecting assembly includes a third link, a threaded post, a wire wheel, a first nut, and a reinforcing tube. The threaded post is fixed inside one side of the third link, the wire wheel is located outside the threaded post, and the outer surface of the other side of the wire wheel is in contact with the outer surface of the third link. The first nut is threaded to the outer surface of the threaded post, and the reinforcing tube is sleeved inside the wire wheel.

[0009] Furthermore, a connecting plate is fixed to the outer surface of the other side of the wire wheel, and a connecting column is fixed to the outer surface of the other side of the reinforcing tube. The connecting column is connected through the inside of the wire wheel, and bolts are fixed inside the connecting plate and the connecting column at both ends.

[0010] Furthermore, a universal joint is fixed to the other side of the third link. There are two sets of universal joints. A second link is fixed between the two sets of universal joints, and a first link is fixed to the other side of the other universal joint.

[0011] Furthermore, the drive assembly includes a frame, casters, a counterweight box, and an electrical box; the casters are fixed to the lower surface of the bottom end of the frame, the counterweight box is fixed to the bottom end inside the frame, and the electrical box is fixed to the top end inside the frame.

[0012] Furthermore, a motor is fixed to one end of the upper surface of the frame, and a gearbox is fixed to the other end of the upper surface of the frame. The output end of the gearbox is fixed to the first connecting rod.

[0013] Furthermore, the adjustment assembly includes a support frame, a threaded rod, a handwheel, and a second nut; the support frame is fixed to one side of the upper surface of the frame, the threaded rod is threadedly connected to the inside of the support frame, the handwheel is fixed to the upper surface of the threaded rod, and the second nut is threadedly connected to the outer surface of the threaded rod, and the second nut is located at both ends of the top crossbeam of the support frame.

[0014] Furthermore, the outer surface of the bottom end of the threaded rod is fixed with the inner ring of the bearing, the outer surface of the bearing is fixed with a fixing tube, the lower surface of the fixing tube is fixed with a fixing bracket, the lower surface of the fixing bracket is fixed with an outer ring, the inner surface of the outer ring is slidably connected with a ball, and the inner surface of the ball is fixed with an inner ring.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, through its set drive and connecting components, allows for the adjustment of the angle between connecting rods under the action of the universal joint when grinding the screw barrel is required. After the wire wheel is inserted into the screw barrel, the motor power is turned on, and the reduction gearbox converts the torque generated by the motor into a low-speed output, thereby driving the rotation of the first connecting rod. Since the first, second, and third connecting rods are connected together, the wire wheel connected to the third connecting rod can be driven to rotate synchronously. After the wire wheel rotates, it applies a pushing force to the frame. With the assistance of the universal wheel, the frame moves horizontally, causing the wire wheel to move horizontally synchronously, thus completing the grinding process inside the screw barrel. This solution, through the set reinforcing tube, forms a double-layer structure, increasing the stability of the wire wheel structure and avoiding damage to the threaded column. This allows subsequent wire wheels to be installed normally. Furthermore, with the cooperation of the drive component, the wire wheel can smoothly move horizontally for a certain length, easily achieving radial cleaning of the extruder barrel.

[0017] II. Based on the first beneficial effect, when the height of the second and third connecting rods relative to the horizontal plane needs to be adjusted with the help of the adjusting components, a rotational force is first applied to the second nut to increase the distance between the second nuts. Then, a rotational force is applied to the handwheel, causing the threaded rod to rotate inside the support frame. At the same time, under the action of the bearing, the bottom of the threaded rod rotates inside the fixed tube, causing the fixed frame at the bottom of the fixed tube to move up and down horizontally, changing the angle between the first and second connecting rods, thereby changing the height of the second connecting rod. During the rotation of the gearbox, the inner ring rotates inside the outer ring under the action of the balls, ensuring that the second connecting rod can rotate normally within the inner ring. The pressure force of the inner ring on the second connecting rod is less than the driving force of the gearbox. This scheme can adjust the angle between the connecting rods, thus allowing the wire wheel to be flexibly placed inside the screw barrel, reducing damage to the wire wheel during placement.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figures 1-3 As shown, this embodiment is a screw barrel grinder, comprising:

[0033] The drive component, the connection component, and the adjustment component are located on one side of the drive component, and the adjustment component is located on top of one side of the drive component.

[0034] The connecting assembly includes a third connecting rod 24, a threaded post 25, a wire wheel 26, a first nut 27, and a reinforcing tube 28. The threaded post 25 is fixed inside one side of the third connecting rod 24, the wire wheel 26 is located outside the threaded post 25, and the outer surface of the other side of the wire wheel 26 is in contact with the outer surface of the third connecting rod 24. The first nut 27 is threaded to the outer surface of the threaded post 25, and the reinforcing tube 28 is sleeved inside the wire wheel 26.

[0035] The third link 24 is an important link connecting the wire wheel 26. It is used to fix the wire wheel 26 to the required position and to make the wire wheel 26 rotate. The threaded post 25 is used to place the wire wheel 26. The first nut 27 is used to fix the wire wheel 26 to the outside of the threaded post 25. The reinforcing tube 28 is used to fit inside the wire wheel 26, forming a double-layer structure to avoid excessive wear and damage to the threaded post 25.

[0036] A connecting plate 291 is fixed to the outer surface of the other side of the wire wheel 26, and a connecting column 29 is fixed to the outer surface of the other side of the reinforcing tube 28. The connecting column 29 is connected through the inside of the wire wheel 26, and bolts 292 are fixed to the inside of the connecting plate 291 and the connecting column 29 at both ends.

[0037] The connecting post 29 is used to confine the reinforcing tube 28 inside the wire wheel 26, and the connecting plate 291 is used to connect with the bolt 292, thereby fixing the connecting post 29 in the required position, and then fixing the reinforcing tube 28 in the required position. When installing the wire wheel 26, the wire wheel 26 is first fixed in the required position, and then the reinforcing tube 28 is fixed inside the wire wheel 26, so as not to affect the rotation of the first nut 27, thus completing the installation of the wire wheel 26.

[0038] On the other side of the third link 24, a universal joint 23 is fixed. There are two sets of universal joints 23. A second link 22 is fixed between the two sets of universal joints 23. On the other side of the other universal joint 23, a first link 21 is fixed.

[0039] Universal joint 23 can flexibly adjust the angle between the connecting rods, so that the wire wheel 26 can be smoothly inserted into the screw barrel. The second connecting rod 22 cooperates with the first connecting rod 21 and the third connecting rod 24 and is connected together through universal joint 23. It plays the role of transmitting force and motion, transmitting the power and motion generated by the drive component to the third connecting rod 24 and the wire wheel 26, so that the wire wheel 26 can perform grinding and processing on the screw barrel according to the expected action. Since the first connecting rod 21, the second connecting rod 22 and the third connecting rod 24 form a certain length, the wire wheel 26 can move horizontally completely inside the screw barrel.

[0040] The drive assembly includes a frame 11, casters 12, a counterweight box 13, and an electrical box 14; the casters 12 are fixed to the lower surface of the bottom end of the frame 11, the counterweight box 13 is fixed to the bottom end inside the frame 11, and the electrical box 14 is fixed to the top end inside the frame 11.

[0041] The frame 11 serves as the supporting frame for the entire screw barrel grinder, bearing all other components and providing the overall structural foundation for the equipment. The casters 12 enable the frame 11 to move horizontally, facilitating the application of pushing force to the wire wheel 26 during screw barrel grinding. The counterweight box 13 is used to balance the weight of the frame 11 and other components mounted on it, ensuring the stability of the equipment during operation. The electrical box 14 houses the motor 15 and related electrical control components, regulating the working status of the motor 15.

[0042] A motor 15 is fixed to one end of the upper surface of the frame 11, and a reduction gearbox 16 is fixed to the other end of the upper surface of the frame 11. The output end of the reduction gearbox 16 is fixed to the first connecting rod 21.

[0043] The motor 15 is the power source of the grinder. It generates torque through operation to provide initial power for subsequent grinding actions. The gearbox 16 reduces and increases the high-speed torque generated by the motor 15, converting it into an output that is suitable for driving the wire wheel 26 to rotate at low speed and has sufficient power.

[0044] Working principle: When grinding the screw barrel is required, the angle between the connecting rods is adjusted under the action of the universal joint 23 so that the wire wheel 26 is placed inside the screw barrel. Then, the power of the motor 15 is turned on, and the reduction gearbox 16 converts the torque generated by the motor 15 into a low-speed output, thereby driving the rotation of the first connecting rod 21. Since the first connecting rod 21, the second connecting rod 22 and the third connecting rod 24 are connected together, the wire wheel 26 connected to the third connecting rod 24 can be driven to rotate synchronously. After the wire wheel 26 rotates, it applies a pushing force to the frame 11. With the assistance of the universal wheel 12, the frame 11 moves horizontally, so that the wire wheel 26 moves horizontally synchronously, thereby completing the grinding process inside the screw barrel.

[0045] This step, through the reinforcement tube 28, forms a double-layer structure, which increases the stability of the wire wheel 26 structure and avoids damage to the threaded post 25. This allows the subsequent wire wheel 26 to be installed normally, and with the cooperation of the drive component, the wire wheel 26 can move horizontally for a certain length smoothly.

[0046] Please see Figure 1 , Figures 4-6 As shown, this embodiment, based on the above embodiment, further includes an adjustment component including a support frame 31, a threaded rod 32, a handwheel 33, and a second nut 34; the support frame 31 is fixed to one side of the upper surface of the frame 11, the threaded rod 32 is threadedly connected to the inside of the support frame 31, the handwheel 33 is fixed to the upper surface of the threaded rod 32, and the second nut 34 is threadedly connected to the outer surface of the threaded rod 32, and the second nut 34 is located at both ends of the top crossbeam of the support frame 31;

[0047] The support frame 31 is used for the threaded rod 32 to rotate inside it. By rotating the threaded rod 32, the height of the bottom fixing tube 35 can be changed. The handwheel 33 makes it convenient to apply rotational force to the threaded rod 32. The second nut 34 is used to fix the threaded rod 32 more accurately and stably in the required position.

[0048] The inner ring of the bearing 36 is fixed to the outer surface of the bottom end of the threaded rod 32. The outer surface of the bearing 36 is fixed to the fixing tube 35. The lower surface of the fixing tube 35 is fixed to the fixing bracket 37. The lower surface of the fixing bracket 37 is fixed to the outer ring 38. The inner surface of the outer ring 38 is slidably connected to the ball 39. The inner surface of the ball 39 is fixed to the inner ring 391.

[0049] The bearing 36 is used to make the threaded rod 32 rotate inside the fixed tube 35, thereby ensuring that the fixed tube 35 maintains a relatively stable vertical movement during the rotation of the threaded rod 32. The fixed bracket 37 is used to support and install the fixed tube 35, and then support and install the outer ring 38. The ball 39 makes the inner ring 391 rotate inside the outer ring 38.

[0050] Working principle: When it is necessary to adjust the height between the second link 22 and the third link 24 and the horizontal plane, first apply a rotational force to the second nut 34 to increase the distance between the second nuts 34, and then apply a rotational force to the handwheel 33, so that the threaded rod 32 rotates inside the support frame 31. At the same time, under the action of the bearing 36, the bottom of the threaded rod 32 rotates inside the fixed tube 35, so that the fixed frame 37 located at the bottom of the fixed tube 35 moves up and down horizontally, changing the angle between the first link 21 and the second link 22, thereby changing the height of the second link 22. During the rotation of the gearbox 16, under the action of the ball 39, the inner ring 391 rotates inside the outer ring 38, thereby ensuring that the second link 22 can rotate normally within the inner ring 391, and the pressure of the inner ring 391 on the second link 22 is less than the driving force of the gearbox 16.

[0051] This step allows for adjustment of the angle between the connecting rods, thereby enabling the wire wheel 26 to be flexibly placed inside the screw barrel, reducing damage to the wire wheel 26 during placement.
