Description

[0027] 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.

[0028] Reference Figure 1-7 A traction device for drilling sealing strips includes a workbench 1, a traction component 2 and an arc-shaped guide platform 3 respectively installed on both sides of the top of the workbench 1, and a plurality of guide rollers 31 are installed at intervals along the length of the inner side of the arc-shaped guide platform 3.

[0029] The traction assembly 2 includes a base plate 21. Two guide rods 22 are parallelly arranged at the top of the base plate 21. A fixed seat 23 is fixedly connected to the bottom of the two guide rods 22. A main traction belt 24 is mounted on the side of the fixed seat 23. A movable seat 25 is slidably sleeved above the two guide rods 22. A secondary traction belt 26 is mounted on the side of the movable seat 25. A top plate 27 is connected to the top of the two guide rods 22. A lifting motor 28 is installed in the middle of the top of the top of the top plate 27. One end of the output shaft of the lifting motor 28 passes through the top plate 27 and is fixedly connected to a threaded rod 29. The movable seat 25 is threaded onto the outside of the threaded rod 29. An L-shaped plate 214 is installed on the side of the base plate 21 away from the guide rods 22. A drive motor 210 is installed on the outer side of the L-shaped plate 214. The output end of the drive motor 210 is connected to the main traction belt 24 to drive its operation.

[0030] By adopting the above technical solution, through the overall layout of the workbench 1, traction component 2 and arc-shaped guide platform 3, the active drive of the main traction belt 24 and the adjustable clamping structure of the traction belt 26 can stably transport the sealing strip. At the same time, the guide roller 31 of the arc-shaped guide platform 3 can assist the smooth transition of the strip, meet the traction requirements of strips of different thicknesses, and improve the versatility and traction stability of the device. The lifting motor 28 drives the threaded rod 29 to move the movable seat 25 up and down along the guide rod 22, which can flexibly adjust the distance between the main and traction belts to further adapt to strips of different specifications.

[0031] The traction belt 26 includes a second belt 261 and a second pulley 262 located at the corners of both ends inside the second belt 261. The shafts at both ends of the second pulley 262 are rotatably connected to a fixed sleeve 263. The fixed sleeve 263 has a threaded positioning hole 264. The movable seat 25 has slots at both ends. A fixed block 251 is welded to the opening end of the slot. A positioning screw 252 is threaded through the side of the fixed block 251, and one end of the positioning screw 252 is threaded through the corresponding threaded positioning hole 264 on the fixed sleeve 263.

[0032] By adopting the above technical solution, and with the cooperation of the fixed sleeve 263, the threaded positioning hole 264, the fixed block 251 and the positioning screw 252, the second pulley 262 and the movable seat 25 are detachably connected. This not only facilitates the installation, replacement and maintenance of the traction belt 26, but also allows for flexible adjustment of the tension of the second belt 261, ensuring the transmission reliability of the traction belt 26.

[0033] A positioning plate 211 is provided on the side of the traction belt 26 away from the movable seat 25. The connection method between the two ends of the positioning plate 211 and the second pulley 262 is the same as the connection method between the movable seat 25 and the fixing sleeve 263 through the fixing block 251 and the positioning screw 252.

[0034] Connecting frames 212 are symmetrically arranged on the outer sides of both ends of the traction belt 26. Each end of the connecting frame 212 is provided with a connecting arm 213. The connecting arms 213 at both ends are fixedly connected to the movable seat 25 and the positioning plate 211 respectively by screws.

[0035] By adopting the above technical solution, by setting the positioning plate 211 and the connecting frame 212, the connection method between the positioning plate 211 and the second pulley 262 is the same as that between the movable seat 25 and the fixed sleeve 263. The connecting arm 213 of the connecting frame 212 is used to reinforce the movable seat 25 and the positioning plate 211, which effectively enhances the structural stability of the traction belt 26, avoids the shaking of the second pulley 262 during operation, and improves the working stability of the traction belt 26.

[0036] The main traction belt 24 includes a first belt 241 and a first pulley 242 located at the two end corners inside the first belt 241. The connection method between the fixed seat 23 and the first pulley 242 is the same as the connection method between the movable seat 25 and the second pulley 262.

[0037] The shaft of the first pulley 242 away from the fixed seat 23 is rotatably mounted on the L-shaped plate 214, and the output shaft of the drive motor 210 is fixedly connected to the shaft of one of the first pulleys 242.

[0038] By adopting the above technical solution, the connection method between the main traction belt 24 and the fixed seat 23 is the same as that between the secondary traction belt 26 and the movable seat 25, which simplifies the assembly process; the drive motor 210 directly drives the first pulley 242 of the main traction belt 24 and is stably supported by the L-shaped plate 214, which ensures efficient power transmission and guarantees the stable operation of the main traction belt 24.

[0039] The fixed base 23 has a through hole for the guide rod 22 to pass through. The rod part of the guide rod 22 located inside the through hole has a locking hole 221. A locking screw 231 is threaded through and installed on the side of the fixed base 23. One end of the locking screw 231 extends into the through hole and is threadedly connected to the locking hole 221.

[0040] By adopting the above technical solution, a locking screw 231 is set on the fixed seat 23, which works in conjunction with the locking hole 221 on the guide rod 22 to achieve a stable fixation between the fixed seat 23 and the guide rod 22, ensuring that the fixed seat 23 will not be displaced along the guide rod 22 during the operation of the device, thereby ensuring the stability of the position of the main traction belt 24.

[0041] The arc-shaped guide platform 3 has an arc-shaped partition 32 inside. Two auxiliary rollers 33 are installed at the top of the arc-shaped partition 32 near the parallel section of the traction component 2. The two auxiliary rollers 33 are parallel to each other and are both perpendicular to the length direction of the parallel section of the arc-shaped guide platform 3.

[0042] By adopting the above technical solution, by setting two auxiliary rollers 33 that are parallel to each other and perpendicular to the length direction of the parallel section of the arc-shaped partition 32 on the arc-shaped guide plate 3, the sealing strip before entering the traction assembly 2 can be pre-positioned to prevent the strip from deviating, thus ensuring the accuracy of the strip traction direction and providing a stable material base for the subsequent drilling process.

[0043] The auxiliary roller 33 includes a chassis 331, a T-shaped rod 332 fixedly connected to the top of the chassis 331, a roller sleeve 333 rotatably sleeved on the outside of the T-shaped rod 332, an adjusting screw 334 fixedly connected to the middle of the bottom end of the chassis 331, a strip hole 321 opened on the arc-shaped partition 32, and a limit nut 335 threadedly sleeved on the bottom end of the adjusting screw 334 through the strip hole 321.

[0044] By adopting the above technical solution, through the cooperation of chassis 331, T-shaped rod 332, roller sleeve 333, adjusting screw 334 and limiting nut 335, the auxiliary roller 33 can be adjusted and fixed along the strip hole 321 of the arc-shaped partition 32, which can be adapted to sealing strips of different widths, enhancing the flexibility and applicability of the pre-positioning function, and further improving the overall traction accuracy.

[0045] Working principle:

[0046] The sealing strip is guided and conveyed by the guide roller 31 of the arc-shaped guide platform 3. After being pre-positioned by the auxiliary roller 33 on the arc-shaped partition 32, it first passes through the punching device set between the arc-shaped guide platform 3 and the traction assembly 2 to complete the punching operation, and then enters the traction assembly 2. The drive motor 210 drives the main traction belt 24 to run, and at the same time the lifting motor 28 adjusts the height of the movable seat 25 through the threaded rod 29, so that the secondary traction belt 26 and the main traction belt 24 clamp the sealing strip. The main traction belt 24 drives the sealing strip and the secondary traction belt 26 to move synchronously through friction, so as to achieve stable traction and conveying of the sealing strip after punching, and ensure that the punching and traction processes are carried out in a continuous manner.

[0047] 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.
