Description

Technical Field

[0001] This utility model relates to the technical field of tire pad processing equipment, and in particular to a tire pad burr trimming device. Background Technology

[0002] Inner tubes are ring-shaped rubber strips used to protect inner tubes from rim wear. They are installed between the inner tube and the rim, with a thicker middle and thinner edges from the inside to the outside. In the manufacturing process, inner tubes are usually molded and pressed together. After molding, excess rubber will remain on the edges of the inner tube, which needs to be trimmed using trimming equipment.

[0003] Existing padding trimming equipment cannot properly secure the padding during trimming, causing it to shift and tilt, which can damage the padding and render it unusable. Utility Model Content

[0004] In view of this, the present invention provides a tire pad tape burr trimming device, the main technical problem to be solved is: the problem that the pad tape is easily damaged when it tilts during trimming.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tire pad trimming device, comprising a base box, a placement column fixedly connected to the lower part of the base box, trimming devices fixedly connected to both sides of the top of the base box, a fixing device fixedly connected to the inside of the trimming device, a moving device threadedly connected to the lower part of the base box, a dustproof window placed on the outside of the base box, the fixing device comprising a fixing cylinder fixedly connected to the inside of the trimming device, a telescopic column movably connected to the inside of the fixing cylinder, a spring fixedly connected between the fixing cylinder and the telescopic column, a connecting frame fixedly connected to the outer end of the telescopic column, and a pressure cylinder movably connected to the inner side of the connecting frame.

[0006] By adopting the above technical solution, the electric telescopic rod is activated, which drives the fixing frame closer to the placement column, and then drives the fixing device closer to the placement column. As it gets closer, the pressure cylinder can contact the padding strip on the outside of the placement column, and the telescopic column is compressed into the fixing cylinder, which can compress the spring. The compression causes the spring to generate a reverse force, which allows the pressure cylinder to firmly press the padding strip, ensuring that the padding strip can be stably attached to the placement column, making it easy to fix and preventing the padding strip from tilting during trimming.

[0007] As a further description of the above technical solution: the bottom box includes a box body, the outer side of the box body is provided with a first screw groove, the outer side of the inner side of the box body is provided with a mounting hole, the lower part of the box body is provided with a second screw groove, and the lower part of the box body is fixedly connected to a base.

[0008] By adopting the above technical solution, the first screw groove is used for screwing in the bolts to fix the dustproof window to the box body, the mounting hole is used for placing the dustproof window, and the base is used to support the box body.

[0009] As a further description of the above technical solution: the dustproof window includes a fixed frame placed on the outside of the box, a dustproof leaf is fixedly connected to the inside of the fixed frame, and bolts are movably connected inside the fixed frame.

[0010] By adopting the above technical solution, the dustproof leaf has a certain dustproof effect and allows air to enter the bottom box through the gaps between the dustproof leaves, which facilitates the heat dissipation of the rotating motor inside the bottom box.

[0011] As a further description of the above technical solution: the moving device includes a fixed column threadedly connected to the lower part of the housing, a turntable fixedly connected to the lower outer side of the fixed column, a rotating column movably connected inside the fixed column, and a moving wheel movably connected to the inner side of the rotating column.

[0012] By adopting the above technical solution, the fixed column can be rotated inside the box by turning the turntable, and it can be raised and lowered inside the box by rotating forward and backward. When the equipment needs to be moved, the moving device can be controlled to move downward so that the moving wheels contact the ground and the base leaves the ground. The moving device can be moved upward to ensure that the moving wheels leave the ground and the base contacts the ground, thus placing the equipment stably.

[0013] As a further description of the above technical solution: the trimming device includes fixed plates fixedly connected to both sides of the top of the box, an electric telescopic rod fixedly connected inside the fixed plate, a fixed frame fixedly connected to one end of the electric telescopic rod near the placement column, a trimming motor fixedly connected to the lower part of the fixed frame, a rotating shaft fixedly connected to the output end of the trimming motor, and a cutter fixedly connected to the top of the rotating shaft.

[0014] By adopting the above technical solution, the electric telescopic rod is activated to move the fixing frame closer to the placement column. As it moves closer, the cutter comes into contact with the padding strip. The trimming motor is activated to make the rotating shaft rotate the cutter. The rotation then cuts and trims the rough edges of the padding strip.

[0015] As a further description of the above technical solution: the placement column includes a rotating motor fixedly connected to the lower part of the box, and the output end of the rotating motor is fixedly connected to the column.

[0016] By adopting the above technical solution, the column can be rotated by starting the rotating motor, which in turn drives the padding strip on the outside of the column to rotate, so that the cutter can trim the edges of the padding strip at various points. At the same time, it can drive the pressure cylinder to rotate, ensuring that the pressure cylinder can always press and fix the padding strip.

[0017] By employing the above technical solution, the tire pad trimming device of this utility model has at least the following beneficial effects:

[0018] Compared with existing technologies, this tire pad trimming device, with its fixing device, facilitates the secure fixation of the pad. In use, the pad is placed over the outside of the column, with the trimmed edge aligned with the cutter. Activating the electric telescopic rod moves the fixing frame closer to the column, which in turn moves the fixing device closer. As it approaches, the pressure cylinder contacts the pad placed over the column, and the compression causes the telescopic rod to retract into the fixing cylinder, compressing the spring. This compression generates a counterforce in the spring, allowing the pressure cylinder to firmly press the pad. This ensures the padding tape adheres stably to the placement column, facilitating its fixation and preventing tilting during trimming. The cutting blade continuously approaches the tape, ensuring it contacts the trimmed edges. Activating the trimming motor causes the shaft to rotate, driving the cutting blade to cut and trim the rough edges of the tape. Simultaneously, activating the rotating motor causes the column to rotate, which in turn rotates the padding tape fitted around the outside of the column, allowing the cutting blade to trim the edges of the tape at various points. This also drives the pressure cylinder to rotate, ensuring the pressure cylinder continuously presses and secures the tape. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Reference Figure 1-4 This utility model provides a tire pad burr trimming device, including a base box 1. A placement column 6 is fixedly connected to the lower part of the base box 1. Trimming devices 4 are fixedly connected to both sides of the top of the base box 1. A fixing device 5 is fixedly connected inside the trimming devices 4. A moving device 3 is threadedly connected to the lower part of the base box 1. A dustproof window 2 is placed on the outside of the base box 1. Specifically, the fixing device 5 includes a fixing cylinder 501 fixedly connected inside the trimming devices 4. A telescopic column 502 is movably connected inside the fixing cylinder 501. The telescopic column 502 can extend and retract inside the fixing cylinder 501. A spring 505 is fixedly connected between the fixing cylinder 501 and the telescopic column 502. A connecting frame 503 is fixedly connected to the outer end of the telescopic column 502. A pressure cylinder 504 is movably connected to the inner side of the connecting frame 503. The pressure cylinder 504 can rotate inside the connecting frame 503, and the distance between the pressure cylinder 504 and the placement column 6 is less than the distance between the cutter 406 and the placement column 6. By activating the electric telescopic rod 402, the fixing frame 403 is brought closer to the placement column 6, which in turn brings the fixing device 5 closer to the placement column 6. As it moves closer, the pressure cylinder 504 comes into contact with the padding strip that is fitted on the outside of the placement column 6. Through compression, the telescopic rod 502 retracts into the fixing cylinder 501, which compresses the spring 505. The compression causes the spring 505 to generate a reverse force, which allows the pressure cylinder 504 to firmly press the padding strip, ensuring that the padding strip can be stably attached to the placement column 6, making it easy to fix and preventing the padding strip from tilting during trimming.

[0026] Furthermore, the bottom box 1 includes a box body 101. The outer side of the box body 101 is provided with a first screw groove 102 for screwing in bolts 203 to fix the dustproof window 2 to the box body 101. The outer side of the inside of the box body 101 is provided with a mounting hole 103 for placing the dustproof window 2. The lower part of the box body 101 is provided with a second screw groove 104. The lower part of the box body 101 is fixedly connected to a base 105 for supporting the box body 101.

[0027] Furthermore, the dustproof window 2 includes a fixed frame 201 placed on the outside of the housing 101. A dustproof leaf 202 is fixedly connected to the inside of the fixed frame 201. A bolt 203 is also movably connected inside the fixed frame 201. The dustproof leaf 202 has a certain dustproof effect and allows air to enter the bottom housing 1 through the gaps between the dustproof leaves 202, which facilitates heat dissipation for the rotating motor 601 inside the bottom housing 1.

[0028] Furthermore, the moving device 3 includes a fixed column 301 threadedly connected to the lower part of the housing 101. A turntable 302 is fixedly connected to the lower outer side of the fixed column 301. By turning the turntable 302, the fixed column 301 can rotate inside the housing 101, and by rotating forward and backward, it can be raised and lowered inside the housing 101. A rotating column 303 is movably connected inside the fixed column 301, and a moving wheel 304 is movably connected to the inner side of the rotating column 303. The rotating column 303 can rotate inside the fixed column 301, and the moving wheel 304 can rotate inside the rotating column 303, enabling it to move. When the equipment needs to be moved, the moving device 3 can be controlled to move downward, so that the moving wheel 304 contacts the ground, and at the same time, the base 105 is lifted off the ground, thus allowing it to move. In use, the moving device 3 is moved upward to ensure that the moving wheel 304 is lifted off the ground and the base 105 contacts the ground, thus stably placing the equipment.

[0029] Furthermore, the trimming device 4 includes fixed plates 401 fixedly connected to both sides of the top of the housing 101. An electric telescopic rod 402 is fixedly connected inside the fixed plate 401. A fixed frame 403 is fixedly connected to one end of the electric telescopic rod 402 near the placement column 6. By activating the electric telescopic rod 402, it can drive the fixed frame 403 closer to the placement column 6. As it gets closer, the cutter 406 can contact the padding strip. A trimming motor 404 is fixedly connected to the lower part of the fixed frame 403. A rotating shaft 405 is fixedly connected to the output end of the trimming motor 404. The cutter 406 is fixedly connected to the top of the rotating shaft 405. By activating the trimming motor 404, the rotating shaft 405 can drive the cutter 406 to rotate. This rotation can cut and trim the rough edges of the padding strip.

[0030] Furthermore, the placement column 6 includes a rotating motor 601 fixedly connected to the lower part of the box 101. The output end of the rotating motor 601 is fixedly connected to the column 602. By starting the rotating motor 601, the column 602 can rotate, which in turn drives the padding strip sleeved on the outside of the column 602 to rotate, so that the cutter 406 can trim the edges of the padding strip at various points. At the same time, it can drive the pressure cylinder 504 to rotate, ensuring that the pressure cylinder 504 can always press and fix the padding strip.

[0031] Working principle:

[0032] In use, the pad is placed on the outside of the column 602, with the trimming edge aligned with the cutter 406. By activating the electric telescopic rod 402, the fixing frame 403 is brought closer to the placement column 6, which in turn brings the fixing device 5 closer to the placement column 6. As it moves closer, the pressure cylinder 504 comes into contact with the pad placed on the outside of the placement column 6, and the telescopic rod 502 retracts into the fixing cylinder 501 through compression, which compresses the spring 505. The compression causes the spring 505 to generate a reverse force, which allows the pressure cylinder 504 to firmly press the pad, ensuring that the pad is stably attached to the placement column 6, facilitating its fixation and preventing the pad from tilting during trimming. As the cutting blade 406 approaches the padding tape, the cutting motor 404 is activated, causing the shaft 405 to rotate and the cutting blade 406 to cut and trim the rough edges of the padding tape. Simultaneously, the rotating motor 601 is activated, causing the column 602 to rotate, which in turn causes the padding tape fitted on the outside of the column 602 to rotate, making it easier for the cutting blade 406 to trim the edges of the padding tape. At the same time, the pressure cylinder 504 is also rotated, ensuring that the pressure cylinder 504 can continuously press and fix the padding tape.
