Description

Technical Field

[0001] The utility model relates to the technical field of automobile sealing strip processing, in particular to an automobile sealing strip cutting device. Background Technique

[0002] Automobile sealing strips are used to ensure that the interior of the automobile can be conveniently sealed during use. During the production of automobile sealing strips, most of them are produced through a raw material conveying part, a single-screw extrusion part, an extrusion die, and shaping and cooling. In order to facilitate transportation, storage, and use, most automobile sealing strips are wound into rolls after production. Since the lengths required for different automobiles are different, it is necessary to cut the rolls of materials. However, when the existing automobile sealing strip cutting devices are in use, most of them traction one end of the sealing strip to move the sealing strip under the cutting knife for cutting. After cutting, it is necessary to re-traction one end of the automobile sealing strip again. In actual use, not only does it affect production efficiency, but also when the sealing strip is traction under the cutting knife, it makes workers prone to the risk of being cut.

[0003] The publication number is: CN220197788U, which discloses an automobile sealing strip cutting device. Through the setting of the conveying component, the device can automatically convey the sealing strip under the cutting knife for automatic cutting when cutting the sealing strip. By rotating the handle, the handle drives the second gear to rotate, the second gear drives the first gear to rotate, the rotation of the first gear drives the threaded rod to rotate. Through the rotation of the threaded rod, the threaded sleeve can move, the movement of the threaded sleeve drives the push plate to move, the movement of the push plate drives the push rod to move, and the push rod drives the second clamping plate to move. Through the movement of the second clamping plate, the sealing strip can be clamped and limited to prevent the sealing strip from shifting. However, the clamping plate in the above cutting device only limits the sealing strip and does not clamp and fix the sealing strip. In actual production, since the uncut part of the sealing strip is relatively long and not fixed at the cutting position, the sealing strip is prone to sliding on the conveyor belt when the conveyor belt rotates. At the same time, accurate cutting cannot be guaranteed during cutting, which is likely to cause errors and thus affect the production of sealing strip cutting.

[0004] Based on this, an automobile sealing strip cutting device is now provided, which can eliminate the drawbacks of the existing devices. Content of the Utility Model

Detailed implementation manner

[0026] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Embodiment 1

[0028] In one embodiment, as Figures 1 - 6 shown, an automobile sealing strip cutting device includes a cutting knife 11 and a first conveyor belt 22. The cutting knife 11 is fixedly arranged at the output end of the hydraulic cylinder 12. The hydraulic cylinder 12 is fixedly arranged in the upper mounting hole of the first mounting bracket 13. The first mounting bracket 13 is fixedly arranged on the upper end of the transmission box 14. A lifting component for supporting the cutting position is arranged below the cutting knife 11. The two first conveyor belts 22 are symmetrically arranged. A plurality of mounting blocks 24 are fixedly arranged at equal intervals on the first conveyor belt 22. The mounting blocks 24 are fixedly connected to the first conveyor belt 22 through fixing strips. Auxiliary support rods are symmetrically arranged at the bottom ends of the mounting blocks 24. A clamping mechanism for clamping the automobile sealing strip is arranged inside each mounting block 24. A conveying mechanism for transferring the cut sealing strip is arranged inside the transmission box 14 at one end of the first conveyor belt 22. The clamping mechanism facilitates clamping and fixing the automobile sealing strip and moving along with the first conveyor belt 22, so that the cutting knife 11 can perform continuous cutting. The conveying mechanism facilitates conveying the cut sealing strip, making it convenient to collect the sealing strip.

[0029] The lifting component includes a lifting plate 15 which is located below the cutting knife 11. A sliding sleeve is fixedly provided at the bottom end of the lifting plate 15. One end of the sliding sleeve is slidably provided with a push rod 16. The sliding sleeve is slidably arranged in a sliding hole at the upper end of a fixed frame 18. The fixed frame 18 is fixedly arranged at the inner bottom end of a transmission box 14. Limiting plates are symmetrically arranged at one end of the sliding sleeve. A support rod is fixedly provided at the concentric position between the bottom end of the lifting plate 15 and the sliding sleeve. A first return spring 17 is arranged between the bottom end of the lifting plate 15 and one end of the push rod 16. Second mounting brackets are symmetrically arranged at one end of the push rod 16. Second racks 21 are fixedly provided at one end of each of the second mounting brackets. Fixed blocks are fixedly provided on one side of each of the second racks 21. Guide sliding rods are slidably arranged on the fixed blocks. The guide sliding rods are fixedly arranged at the inner bottom end of the transmission box 14. First gears 20 are meshed with the second racks 21. The rotation shafts of the first gears 20 are rotatably arranged in mounting holes inside the transmission box 14. First racks 19 are meshed with the first gears 20. The two first racks 19 are respectively fixedly arranged at both ends of a third mounting bracket. The third mounting bracket is fixedly arranged on the output end of a hydraulic cylinder 12. During use, when the cutting knife 11 first cuts the automotive sealing strip, the output end of the hydraulic cylinder 12 drives the cutting knife 11 to move. While the output end of the hydraulic cylinder 12 is moving, it drives the two first racks 19 to move through the third mounting bracket. The two first racks 19 are respectively meshed with the two first gears 20, so that the first gears 20 drive the second racks 21 to move simultaneously. The two second racks 21 drive the push rod 16 to move. The push rod 16 pushes the lifting plate 15 to move. When the cutting knife 11 contacts the sealing strip, the upper end of the lifting plate 15 contacts the sealing strip simultaneously. At the same time, the upper ends of the limiting plates at one end of the sliding sleeve are in close contact with the inner bottom end of the fixed frame 18. When the cutting knife 11 continues to move to cut the sealing strip, the lifting plate 15 no longer moves, and the push rod 16 slides inside the sliding sleeve. After cutting is completed, the output end of the hydraulic cylinder 12 drives the cutting knife 11 back to the initial position, and at the same time the push rod 16 drives the lifting plate 15 back to the initial position.

[0030] The clamping mechanism includes sliding rods 25. The sliding rods 25 are slidably arranged inside the mounting blocks 24. Clamping plates 26 are fixedly arranged at one ends of the sliding rods 25. Sliding plates are fixedly arranged on the sliding rods 25. Guide chutes are arranged inside the mounting blocks 24 and at the moving positions of the sliding plates. Second return springs 27 are arranged between one sides of the sliding plates and the inner sides of the guide chutes. Guide plates 29 are arranged at positions corresponding to the upper ends of the first conveyor belts 22 inside the transmission box 14. The guide plates 29 are in close contact with one ends of the sliding rods 25. First driving rollers and first transmission rollers are arranged at both ends of the two first conveyor belts 22. Transmission shafts are fixedly arranged between the two first driving rollers and the first transmission rollers. Retaining plates 23 are arranged on one sides of the first conveyor belts 22. Fixed tubes are arranged at the rotating shafts on one sides of the retaining plates 23 and at one sides of the first driving rollers and the first transmission rollers. The fixed tubes are fixedly arranged inside the transmission box 14. A second gear is fixedly arranged on the rotating shaft on one side of one of the first driving rollers. A third gear is meshed with the second gear. The third gear is fixedly arranged at the output end of the motor 28. The motor 28 is fixedly arranged on the upper end of the support plate. The support plate is fixedly arranged on one side of the transmission box 14. When in use, when it is necessary to cut the automotive sealing strip, the automotive sealing strip is placed between the two clamping plates 26. Then the motor 28 is started. The output end of the motor 28 drives the third gear to rotate. The third gear meshes with the second gear to drive the two first driving rollers to rotate. By the cooperation of the first driving rollers and the first transmission rollers, the two first conveyor belts 22 rotate simultaneously. When the first conveyor belts 22 rotate, they drive a plurality of mounting blocks 24 to rotate. When the mounting blocks 24 rotate to the upper ends of the first conveyor belts 22, one ends of the sliding rods 25 contact the inclined surfaces at one ends of the guide plates 29, and the guide plates 29 guide the sliding rods 25. When one ends of the sliding rods 25 contact the flat surfaces of the guide plates 29, the two clamping plates 26 can clamp and fix the automotive sealing strip. As the first conveyor belts 22 drive the mounting blocks 24 to move, the two clamping plates 26 can traction the automotive sealing strip. When any position between the two mounting blocks 24 moves below the cutting knife 11 and meets the set cutting position, the first conveyor belts 22 stop rotating, and the cutting knife 11 cuts the automotive sealing strip. The cut automotive sealing strip is still clamped and fixed by the two clamping plates 26. Then the motor 28 is started again to drive the automotive sealing strip to move a fixed length, so as to perform continuous cutting. At the same time, the clamping plates 26 drive the cut automotive sealing strip to move. It should be noted that the motor 28 in this application can be a servo motor or other motors, as long as it can rotate a fixed number of turns and stop each time.

[0031] Ball bearings are arranged at one ends of the sliding rods 25. When in use, it is convenient to reduce the wear between one ends of the sliding rods 25 and the guide plates 29.

[0032] The conveying mechanism includes a second conveying belt 33, which is arranged between the two first conveying belts 22, and the second conveying belt 33 is arranged at one end of the guide plate 29. The second conveying belt 33 is provided with a second driving roller and a second transmission roller at both ends, respectively. The first rotating plates are rotatably provided on the rotating shafts at both ends of the second driving roller and the second transmission roller. The first rotating plates are fixedly provided at the bottom end of the transmission box 14. A fixed shaft is fixedly provided on the rotating shaft at one end of the second driving roller. The fixed shaft is rotatably provided in a mounting hole on one side of the transmission box 14, and a driven wheel is fixedly provided at one end of the fixed shaft. The driven wheel is connected to the driving wheel through a belt, and the driving wheel is fixed on a rotating shaft on one side of a first transmission roller. When in use, after the two clamping plates 26 drive the cut automobile sealing strip to move to the other end of the guide plate 29, one end of the guide plate 29 is tilted. Under the action of the second return spring 27, the distance between the two clamping plates 26 gradually increases, so that the automobile sealing strip falls on the upper end of the second conveyor belt 33. At the same time, when the first conveyor belt 22 rotates, the first transmission roller drives the second conveyor belt 33 to rotate through the belt, so that the cut automobile sealing strip can be easily transported.

[0033] A material guide plate 34 is provided below one end of the second conveyor belt 33. The material guide plate 34 is fixed between the two first rotating plates. The material guide plate 34 is inclined. When in use, after the second conveyor belt 33 transfers the sealing strip to one end of the second conveyor belt 33, the sealing strip falls on the upper end of the material guide plate 34. Since the material guide plate 34 is symmetrically arranged, it is convenient to collect the sealing strip.

[0034] A guide wheel 35 is symmetrically provided at one end of the first conveyor belt 22, and the rotating shafts at both ends of the guide wheel 35 are respectively arranged in the rotating holes on one side of two second rotating plates, and the second rotating plates are fixed at the bottom end of the transmission box 14. When in use, when the automobile sealing strip needs to be cut, one end of the automobile sealing strip is passed between the two guide wheels 35 to guide the sealing strip.

[0035] Example 2

[0036] The difference from Embodiment 1 lies in that one side of the guide plate 29 is fixedly connected to the output ends of a number of telescopic rods 30 respectively, and a number of the telescopic rods 30 are all fixedly connected to the inner side of the transmission box 14. A first fixing plate 31 is fixedly provided on one side of the guide plate 29, and threaded holes are provided on one side of the first fixing plate 31. The two first fixing plates 31 are respectively arranged at both ends of the bidirectional screw 32. The bidirectional screw 32 is rotatably arranged in the rotation holes on both sides of the transmission box 14. When in use, when it is necessary to clamp sealing strips with different widths, rotate the bidirectional screw 32. Under the action of the thread, the first fixing plate 31 drives the guide plate 29 to move, so that the two guide plates 29 move simultaneously and in opposite directions, thereby adjusting the distance between the two clamping plates 26.

[0037] The above embodiments disclose a cutting device for automotive sealing strips. When cutting an automotive sealing strip, one end of the automotive sealing strip is passed through between two guide wheels 35 to guide the sealing strip and make the automotive sealing strip located between two clamping plates 26. Subsequently, the motor 28 is started. The output end of the motor 28 drives the third gear to rotate. The third gear meshes with the second gear to drive two first driving rollers to rotate. By using the cooperation of the first driving rollers and the first transmission rollers, two first transmission belts 22 rotate simultaneously. When the first transmission belts 22 rotate, a number of mounting blocks 24 are driven to rotate. When the mounting block 24 rotates to the upper end of the first transmission belt 22, one end of the sliding rod 25 contacts the inclined surface at one end of the guide plate 29, and the guide plate 29 guides the sliding rod 25. When one end of the sliding rod 25 contacts the flat surface of the guide plate 29, the two clamping plates 26 can clamp and fix the automotive sealing strip. As the first transmission belt 22 drives the mounting block 24 to move, the two clamping plates 26 can traction the automotive sealing strip. When any position between the two mounting blocks 24 moves below the cutting knife 11 and meets the set cutting position, the first transmission belt 22 stops rotating. The output end of the hydraulic cylinder 12 drives the cutting knife 11 to move. While the output end of the hydraulic cylinder 12 moves, it drives two first racks 19 to move through the third mounting frame. The two first racks 19 respectively mesh with two first gears 20, so that the first gears 20 drive the second racks 21 to move simultaneously. The two second racks 21 drive the push rod 16 to move. The push rod 16 pushes the lifting plate 15 to move. When the cutting knife 11 contacts the sealing strip, the upper end of the lifting plate 15 contacts the sealing strip simultaneously. At the same time, the upper end of the limiting plate at one end of the sliding sleeve closely adheres to the inner bottom end of the fixed frame 18. When the cutting knife 11 continues to move to cut the sealing strip, the lifting plate 15 no longer moves, and the push rod 16 slides inside the sliding sleeve. After cutting, the output end of the hydraulic cylinder 12 drives the cutting knife 11 back to the initial position, and at the same time, the push rod 16 drives the lifting plate 15 back to the initial position. The cut automotive sealing strip is still clamped and fixed by the two clamping plates 26. Subsequently, the motor 28 is started again to drive the automotive sealing strip to move a fixed length, so as to perform continuous cutting. At the same time, the clamping plates 26 drive the cut automotive sealing strip to move. When the two clamping plates 26 drive the cut automotive sealing strip to move to the other end of the guide plate 29, one end of the guide plate 29 is inclined. Under the action of the second return spring 27, the distance between the two clamping plates 26 gradually increases, so that the automotive sealing strip falls onto the upper end of the second transmission belt 33. At the same time, when the first transmission belt 22 rotates, the first transmission roller drives the second transmission belt 33 to rotate through the belt, which facilitates the transfer of the cut automotive sealing strip.

[0038] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
