Description

Technical Field

[0001] This utility model belongs to the field of corrugated pipe processing technology, and specifically relates to a fixed-distance cutting device for corrugated pipe production. Background Technology

[0002] A bellows is a tubular elastic sensing element made of foldable corrugated sheets connected along the folding and stretching direction. Bellows are widely used in instrumentation, primarily as measuring elements in pressure gauges, converting pressure into displacement or force. Bellows have thin walls, high sensitivity, and a measurement range from tens of Pascals to tens of megapascals. Bellows mainly include metal bellows, bellows expansion joints, bellows heat exchange tubes, diaphragm boxes, and flexible metal tubes, etc.

[0003] Chinese Patent CN220515561 U discloses a cutting device for corrugated pipe production, relating to the field of corrugated pipe processing technology. The cutting device includes a mounting base, a movable cutting device, a guide frame, and a dust collection device. The movable cutting device is fixedly mounted on the top of the mounting base. The guide frame is fixedly mounted on the front side of the top of the base. The dust collection device is fixedly mounted on the top of the mounting base and located at the bottom of the movable cutting device. A fixed platform is fixedly connected to the top of the mounting base. A movable groove is formed on the top of the fixed platform, and several feeding rings are arranged inside the movable groove at equal intervals. A transmission assembly is fixedly connected to the right side of the fixed platform. A lower pressure roller is provided on the top of the fixed platform, and adjustment mechanisms are fixedly connected to both sides of the top of the fixed platform.

[0004] Some cutting equipment lacks a feeding mechanism, requiring users to manually feed the corrugated pipe. Manual feeding cannot ensure stability and can easily lead to deviations during processing. The aforementioned document describes a feeding ring with rubber protrusions fixed to its surface to hold the corrugated pipe in place, allowing the feeding ring to feed the pipe in conjunction with the lower pressure roller. However, the rubber protrusions on the drive roller are intermittent, which can prevent the corrugated pipe from engaging properly when feeding larger diameter pipes.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a fixed-distance cutting device for corrugated pipe production, including a support assembly. The top of the support assembly is provided with a first limiting assembly and a second limiting assembly. A linkage assembly is provided between the first limiting assembly and the second limiting assembly. The top of the support assembly is provided with a cutting assembly.

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a fixed-distance cutting device for corrugated pipe production, including a support component 1. The top of the support component 1 is provided with a first limiting component 2 and a second limiting component 3. A linkage component 4 is provided between the first limiting component 2 and the second limiting component 3. The top of the support component 1 is provided with a cutting component 5. The first limiting component 2 and the second limiting component 3 are used to limit the corrugated pipe. The linkage component 4 is used to make the first limiting component 2 and the second limiting component 3 move simultaneously.

[0031] The corrugated pipe is passed between the first limiting component 2 and the second limiting component 3 on the support component 1. The second limiting component 3 is activated so that it drives the first limiting component 2 to move through the linkage component 4, changing the distance between the first limiting component 2 and the second limiting component 3, so that the first limiting component 2 and the second limiting component 3 can limit the corrugated pipe, and the first limiting component 2 is fitted with the outer surface of the corrugated pipe. The first limiting component 2 is activated, and after the first limiting component 2 pushes the corrugated pipe to move a certain distance, the cutting component 5 on the support component 1 is activated. The cutting component 5 can cut the corrugated pipe, and the cut corrugated pipe falls on the support component 1.

[0032] This utility model connects the first limiting component 2 and the second limiting component 3. The lower half of the first limiting component 2 can be fitted with the corrugated pipe, allowing the first limiting component 2 to push the corrugated pipe to move. The first limiting component 2 and the second limiting component 3 are both located on the top of the support component and are slidably connected to it. The first limiting component 2 and the second limiting component 3 limit the corrugated pipe from the top, bottom, left and right directions, respectively, to prevent the corrugated pipe from rolling unnecessarily. The distance between the first limiting component 2 and the second limiting component 3 can be adjusted to adapt to corrugated pipes of different diameters, making it more flexible.

[0033] In one embodiment, the support component 1 includes a column 101, a workbench 102 is fixedly connected to the top of the column 101, a connecting column 103 is fixedly installed on the top of the workbench 102, and a receiving hopper 104 is fixedly connected to the upper end of the connecting column 103. The receiving hopper 104 is used to receive the cut corrugated pipe.

[0034] There are four sets of uprights 101, which are symmetrically fixed to the bottom of the workbench 102. There are multiple sets of connecting columns 103, which are used to support the receiving hopper 104. The cut corrugated pipe falls into the receiving hopper 104.

[0035] In one embodiment, the first limiting component 2 includes a first motor 201, which is fixedly mounted on the top of the workbench 102. A pusher roller 202 is fixedly connected to the output shaft of the first motor 201. Supports 203 are rotatably connected to both ends of the pusher roller 202. The output shaft of the first motor 201 is rotatably connected to the support 203. The support 203 is fixedly mounted on the top of the workbench 102. A fixed cylinder 204 is fixedly mounted on the top of the workbench 102. A spring 205 is fixedly connected inside the fixed cylinder 204. A limiting plate 206 is fixedly connected to the upper end of the spring 205. A sliding rod 207 is fixedly connected to the top of the limiting plate 206. A side plate 208 is fixedly mounted to the upper end of the sliding rod 207. A pressure roller 209 is rotatably connected to the outer surface of the side plate 208. The limiting plate 206 and the sliding rod 207 are slidably connected inside the fixed cylinder 204.

[0036] The outer surface of the pusher roller 202 has a groove. When the corrugated tube is placed between the pusher roller 202 and the pressure roller 209, the corrugated tube fits into the groove on the pusher roller 202. When the first motor 201 is started, the output shaft of the first motor 201 drives the pusher roller 202 to rotate. The pusher roller 202 pushes the corrugated tube to move. The pressure roller 209 limits the corrugated tube on the pusher roller 202 to prevent the corrugated tube from tilting up. Pushing the side plate 208 can drive the pressure roller 209 to move, changing the distance between the pressure roller 209 and the pusher roller 202. The movement of the side plate 208 drives the sliding rod 207 and the limiting plate 206 to move. The limiting plate 206 can stretch the spring 205 to deform it. At this time, the spring 205 can exert a pulling force on the pressure roller 209 to press the corrugated tube.

[0037] In one embodiment, the second limiting component 3 includes a second motor 301. A screw 302 is fixedly connected to the output shaft end of the second motor 301. The screw 302 is rotatably connected to the worktable 102. Two sets of sliding seats 303 are threadedly connected to the outer surface of the screw 302. A support plate 304 is fixedly installed on the top of each set of sliding seats 303. A movable plate 305 is fixedly installed on the outer surface of the support plate 304. A plurality of rotating columns 306 are rotatably connected to the outer surface of the movable plate 305.

[0038] When the second motor 301 is started, the output shaft of the second motor 301 drives the screw 302 to rotate. The rotation tendency of the sliding seat 303 on the screw 302 is blocked by the worktable 102. At this time, the screw 302 can drive the two sets of sliding seats 303 to move the support plate 304 and the moving plate 305. The rotating column 306 on the moving plate 305 approaches the corrugated tube on the pusher roller 202 to limit it. During the movement of the corrugated tube, the corrugated tube contacts the rotating column 306. The rotating column 306 can reduce the friction by its own rotation.

[0039] In one embodiment, the linkage component 4 includes a trapezoidal plate 401, which is fixedly installed on the side of the movable plate 305. A groove 402 is provided on the outer surface of the trapezoidal plate 401. A pulley 403 is slidably connected inside the groove 402. A bracket 404 is rotatably connected to the outer surface of the pulley 403. The bracket 404 is fixedly installed at the bottom of the side plate 208.

[0040] The movable plate 305 drives the trapezoidal plate 401 to move, and the pulley 403 moves along the groove 402 on the trapezoidal plate 401, so that the pulley 403 pushes the bracket 404 to gradually rise. The bracket 404 pushes the side plate 208 and the pressure roller 209 to move upward, which can increase the distance between the pressure roller 209, the pusher roller 202 and the two sets of movable plates 305.

[0041] In one embodiment, the cutting assembly 5 includes a slide rail 501, which is fixedly installed on the top of the worktable 102. An electric slider 502 is slidably connected to the outer surface of the slide rail 501. A third motor 503 is fixedly connected to the top of the electric slider 502. A cutting blade 504 is fixedly installed on the output shaft of the third motor 503.

[0042] Start the third motor 503. The output shaft of the third motor 503 drives the cutting blade 504 to rotate. Start the electric slider 502. The electric slider 502 drives the cutting blade 504 to move along the slide rail 501, so that the cutting blade 504 contacts the corrugated pipe and cuts it. The cut corrugated pipe falls onto the receiving hopper 104.

[0043] In one embodiment, for the workbench 102, a mounting bracket 6 is fixedly installed on the side of the workbench 102, and the second motor 301 is fixedly installed on the top of the mounting bracket 6.

[0044] Mounting bracket 6 is used to support the second motor 301 and provide a fixed position for mounting the second motor 301.

[0045] Through the above technical solution, 1. By connecting the first limiting component 2 and the second limiting component 3, the lower half of the first limiting component 2 can be engaged with the bellows, allowing the first limiting component 2 to push the bellows to move. Both the first limiting component 2 and the second limiting component 3 are located at the top of the support component and are slidably connected to it. The first limiting component 2 and the second limiting component 3 limit the bellows from four directions: up / down and left / right, respectively, preventing unnecessary lateral rolling of the bellows. The distance between the first limiting component 2 and the second limiting component 3 can be adjusted. 1. The joint allows it to adapt to corrugated pipes of different diameters, making it more flexible; 2. Through the connection between the bracket 404 and the side plate 208, when the moving plate 305 drives the trapezoidal plate 401 to move, the pulley 403 on the bracket 404 moves along the sliding groove 402 on the trapezoidal plate 401, so that the bracket 404 gradually rises to push the side plate 208 and the pressure roller 209 to move upward. At the same time, the two sets of moving plates 305 move away from each other, so that they can limit the corrugated pipes with larger diameters. The adjustment of the pressure roller 209 and the two sets of moving plates 305 can be carried out simultaneously, which is more convenient to use.
