Description

Technical Field

[0001] This utility model relates to the technical field of rubber mixing machines, and in particular to a rubber cutting device for a rubber mixing machine. Background Technology

[0002] Rubber mixing mills are important pieces of equipment in the rubber industry, mainly used for processing rubber such as plasticizing and mixing. When rubber comes out of the mixing mill, there will be some burrs and other impurities on the surface. In order to facilitate subsequent rubber processing, a rubber cutting device is used to remove these burrs and other impurities. Although existing rubber cutting devices can remove burrs and other impurities, when a typical rubber cutting device is cutting burrs normally, the contact area between the blade and the rubber is relatively fixed, which will cause the blade to wear more concentratedly in that area. This will result in that area of ​​the blade becoming unusable, while the rest of the blade area can still be used normally, requiring the replacement of new blades to work properly, resulting in unnecessary waste. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rubber cutting device for a rubber mixing machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rubber cutting device for a rubber mixing mill includes a base with multiple sets of first rollers rotatably connected to the base. Grooves are formed at one and another end of the base. Multiple sets of push rods are mounted on the base, with one end of each push rod connected to a plate. A first opening is formed in the plate, through which a frame is movably inserted. A blade is mounted on the frame. A first motor is mounted on the plate, and a reciprocating screw is mounted at the output end of the first motor. The reciprocating screw is rotatably connected to the plate, and a screw sleeve is threaded onto the reciprocating screw, connecting to the frame. Multiple sets of second rollers are rotatably connected to the plate.

[0006] Preferably, a second opening is provided at the base, and a sliding plate is connected to the base, the sliding plate being connected to the second opening.

[0007] Preferably, a sliding rod is connected to the first opening, and the sliding rod is slidably connected to the frame.

[0008] Preferably, a third port is provided at one end and the other end of the base.

[0009] Preferably, each of the multiple sets of the first rollers is connected to a double-groove pulley, and the multiple sets of double-groove pulleys are driven by multiple sets of belts.

[0010] Preferably, a second motor is installed at the base, and the output end of the second motor is connected to the corresponding first roller.

[0011] Preferably, the bottom end of the blade body and the bottom ends of the multiple sets of second roller bodies are located on the same horizontal line.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the coordination between the reciprocating screw, screw sleeve, frame, and cutter body, when the reciprocating screw is driven by a motor to rotate, the reciprocating screw will drive the screw sleeve to move the frame and cutter body laterally back and forth. In this way, when the cutter removes burrs and other impurities from the rubber conveyed between the first and second rollers, different parts of the blade can participate in the cutting in turn, making the wear area more widely distributed on the blade. At the same time, the lateral back and forth movement disperses heat at different parts of the blade, reducing the possibility of local overheating. This helps maintain the performance of the cutter body, slows down the wear of the cutter material due to high temperature, such as softening and deformation, and can extend the service life of the cutter body, reduce the frequency of cutter body replacement, and avoid unnecessary waste.

[0014] 2. Through the cooperation between the base, the second port and the slide plate, when the cutter body is removing impurities from the rubber, the removed impurities can fall into the slide plate through the gaps between multiple sets of first rollers and be discharged in the second port area. This can discharge the fallen debris and, to a certain extent, prevent the debris from affecting the conveying stability of the rubber by the first and second rollers. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 A rubber cutting device for a rubber mixing mill includes a base 1, with multiple sets of first rollers 2 rotatably connected to the base 1. Grooves 3 are provided at one and the other ends of the base 1, allowing the cutter body 11 to reciprocate laterally at the base 1 after descent. Multiple sets of push rods 4 are mounted on the base 1, driving a plate 5 to move up and down, thereby adjusting the distance between the first rollers 2 and the second rollers 19 to accommodate rubber sheets of different thicknesses. The first rollers 2 are the main components for rubber conveying. The surface of the first rollers 2 undergoes special treatment to have a certain roughness to increase friction with the rubber, ensuring smooth movement of the rubber on the first rollers 2 and the second rollers 19. The second roller 2 cooperates with the first roller 19 to form a stable clamping and conveying path for the rubber, ensuring the accuracy of the rubber's position and the stability of its movement during the cutting process. One end of multiple push rods 4 is connected to a plate 5. A first opening 6 is provided on the plate 5, through which a frame 10 is movably inserted. A blade 11 is installed on the frame 10, and a first motor 7 is installed on the plate 5. The model of the first motor 7 is selected according to actual working requirements. A reciprocating screw 8 is installed at the output end of the first motor 7. The reciprocating screw 8 is rotatably connected to the plate 5. A screw sleeve 9 is threadedly connected to the reciprocating screw 8 and is connected to the frame 10. When the reciprocating screw 8 rotates, it can drive the screw sleeve 9 to move the frame 10 and the blade 11 laterally back and forth. Multiple sets of second rollers 19 are rotatably connected to the plate 5. Through the lateral back and forth movement of the blade 11, different parts of the blade participate in cutting in turn, resulting in a wider distribution of wear areas on the blade and avoiding excessive local wear. Meanwhile, the lateral reciprocating movement helps to disperse the heat generated during the cutting process, reducing problems such as softening and deformation of the tool material caused by excessive local temperature, effectively extending the service life of the tool body 11, reducing the frequency of tool replacement, and lowering production costs.

[0023] In this embodiment, a second opening 12 is provided at the base 1, and a sliding plate 13 is connected to the base 1. The sliding plate 13 is connected to the second opening 12. The cooperation between the sliding plate 13 and the second opening 12 utilizes gravity to realize the automatic sliding and discharge of impurities, thus avoiding the accumulation of impurities between the rollers or other components. This not only prevents impurities from interfering with the rubber conveying process and ensures smooth flow of rubber within the device, but also reduces the probability of equipment failures such as roller wear and jamming caused by impurity accumulation, improving the overall reliability and stability of the equipment and extending the maintenance cycle. A slide rod 14 is connected to the first port 6, and the slide rod 14 is slidably connected to the frame 10. The slide rod 14 can guide the frame 10 to move laterally. A third port 17 is opened at one end and the other end of the base 1. A double groove pulley 15 is connected to each of the multiple sets of first rollers 2. The multiple sets of double groove pulleys 15 are driven by multiple sets of belts 16. A second motor 18 is installed at the base 1. The model of the second motor 18 is selected according to the actual working requirements. The output end of the second motor 18 is connected to the corresponding first roller 2. The bottom end of the cutter body 11 is on the same horizontal line as the bottom end of the multiple sets of second rollers 19, so that when the second roller 19 contacts the rubber, the cutter body 11 can contact the rubber, thereby removing impurities from the rubber.

[0024] The working principle of this embodiment is as follows: In use, insert the external connector into the third port 17 at one end and the other end of the base 1, and place the base 1 on the corresponding position of the rubber mixing mill. After installation, when the rubber is discharged from the rubber mixing mill, the push rod 4 can be used to drive the plate 5 to move downward, thereby adjusting the distance between the second roller 19 and the first roller 2 at the base 1. This allows for the rubber to be adhered and guided. The first motor 7 and the second motor 18 are connected to an external power supply and drive device. The second motor 18, in conjunction with multiple sets of double-groove pulleys 15 and belts 16, drives the rotation of multiple sets of first rollers 2. The rubber is conveyed by a first motor 7 driving a reciprocating screw 8 to move the screw sleeve 9, frame 10 and cutter body 11 laterally. The cutter body 11 can remove burrs and other impurities from the upper end face of the rubber. The reciprocating movement allows different parts of the blade to participate in the cutting in turn, so that the wear area is more widely distributed on the blade, thereby extending the life of the cutter body 11. The cut debris falls between multiple sets of first rollers 2 to the slide plate 13, and then is discharged at the second outlet 12, so as to avoid the debris affecting the conveying stability of the rubber by the first rollers 2 and the second rollers 19.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
