Technical Field
[0001] This utility model relates to the field of cable protection pipe processing, and more specifically, to an automated cutting device for processing MPP cable protection pipes. Background Technology
[0002] MPP cable protection pipe is a type of power cable protection pipe made from modified polypropylene as the main raw material through a special process. It is mainly used for underground laying protection of power cables and communication cables, and has the characteristics of high strength, high temperature resistance, and corrosion resistance.
[0003] A search revealed that Chinese Patent Publication No. CN217195579U discloses "a cutting device for the production and processing of MPP cable protection pipes, including a cutting table, on the top of which a protection pipe body is placed. Two support frames are fixedly connected to the top of the cutting table, and the tops of the two support columns are fixedly connected to the same support platform. A fixing hole is provided on the support platform, and a fixing column is slidably connected in the fixing hole. The bottom end of the fixing column extends to the bottom of the support platform and is fixedly connected to a cutting motor. This utility model limits the cutting motor by moving it up and down and positioning it, preventing hand fatigue and hand tremors caused by manually holding the cutting machine for a long time, which affects the cutting accuracy. The two clamping plates can fix and clamp the protection pipe body before the cutting motor cuts, preventing the protection pipe body from slipping during cutting, thus meeting the user's needs." However, the following defects still exist:
[0004] The current device requires the user to manually push and rotate the MPP protective tube before cutting it. This is labor-intensive and time-consuming over long periods of use. Furthermore, the manual method makes it difficult to accurately determine the cutting length, resulting in low efficiency. Therefore, an automated cutting device for processing MPP cable protective tubes is proposed. Utility Model Content
[0005] The purpose of this utility model is to address the current problem that before cutting MPP protective tubes, users need to manually push and rotate the protective tubes to make the cuts. This is laborious and time-consuming over a long period of time, and the manual method cannot accurately determine the cutting length of the protective tubes, resulting in low work efficiency.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] The present invention is as follows: an automated cutting equipment for processing MPP cable protection pipes, including an operating table, a cutting mechanism for processing the protection pipe is provided on one side of the operating table, and a clamping component for improving the movement stability of the protection pipe is provided on one side of the cutting mechanism.
[0008] The cutting mechanism includes a servo motor bolted to one side of the operating table. A lead screw is coaxially mounted on the output end of the servo motor. Two stabilizing rods are fixedly connected to one side of the operating table. A moving plate is threaded onto the outer wall of the lead screw. A placement groove is formed on one side of the moving plate. A geared ring is rotatably connected to the inner wall of the placement groove. A stabilizing plate is bolted to the side of the moving plate near the placement groove. A reduction motor is bolted to one side of the stabilizing plate. A gear is coaxially mounted on the output end of the reduction motor. A placement ring is fixedly connected to the inner wall of the geared ring. Two first electric push rods are mounted on one side of the placement ring. An arc-shaped plate is mounted on the output end of each of the two first electric push rods. A cutting assembly is mounted on the top of the operating table.
[0009] As a preferred technical solution of this utility model, the cutting assembly includes a support frame fixedly connected to the top of the operating table. A second electric push rod is provided on one side of the support frame, and a mounting frame is provided at the bottom of the second electric push rod. A first motor is bolted to one side of the mounting frame, and a cutting blade is coaxially provided at the output end of the first motor. An extension plate is fixedly connected to the side of the operating table near the support frame. A third electric push rod is provided on one side of the operating table, and a sliding plate is provided at the output end of the third electric push rod. An installation groove is provided inside the extension plate, and an installation frame is fixedly connected to the inner wall of the installation groove. A pressure sensor is provided on the inner wall of the installation frame. A push plate is slidably connected inside the installation groove, and a contact rod is fixedly connected to the side of the push plate near the installation groove. A spring is fixedly connected between the push plate and the installation frame. A controller is provided on one side of the operating table.
[0010] As a preferred technical solution of this utility model, the clamping assembly includes two fixed plates fixedly connected to the side of the moving plate away from the stabilizing plate. Each of the two fixed plates is provided with a telescopic cylinder on its opposite side, and each of the output ends of the two telescopic cylinders is provided with a clamping plate.
[0011] As a preferred technical solution of this utility model, a bracket is fixedly connected to one side of the operating table, and a placement block is fixedly connected to the top of the bracket. A V-shaped groove is opened inside the placement block.
[0012] As a preferred technical solution of this utility model, an inclined plate is fixedly connected to one side of the support frame, and a panoramic camera is provided on one side of the inclined plate, with the panoramic camera facing the cutting plate.
[0013] As a preferred technical solution of this utility model, a guide rail is fixedly connected to one side of the operating table.

[0014] As a preferred technical solution of this utility model, a stabilizing ring is fixedly connected to the outer wall of the placement ring, and the stabilizing ring is rotatably connected to the inside of the stabilizing plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. The cutting mechanism enables automatic length-fixed cutting of MPP cable protection pipes. Activating two first electric push rods clamps the pipe to be cut within a moving plate. Starting the servo motor causes the lead screw to rotate, moving the moving plate closer to the cutting blade. When one end of the protection pipe touches the push plate, the spring contracts, causing the contact rod to contact the pressure sensor. The controller then shuts off the servo motor and activates the second electric push rod to descend. The cutting blade touches the outer wall of the protection pipe, simultaneously activating the first motor and the reduction motor. The first motor drives the cutting blade to rotate at high speed, while the reduction motor, through gears and a gear ring, drives the protection pipe clamped by the first electric push rod to rotate, performing the cutting operation. This reduces manual operation and significantly improves work efficiency.
[0017] 2. By setting up the clamping components, the stability of the MPP cable protection pipe during movement is improved. When the protection pipe moves with the moving plate, two telescopic cylinders are activated to clamp the outer wall of the protection pipe with two clamping plates, which improves the stability of the protection pipe during movement. When cutting the protection pipe, the two telescopic cylinders are activated again to release the clamping of the protection pipe and avoid affecting the subsequent rotational cutting of the protection pipe.

[0026] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0029] like Figure 1 and Figure 2 As shown, this embodiment proposes an automated cutting device for processing MPP cable protection pipes, including an operating table 1, a cutting mechanism 2 for processing the protection pipe is provided on one side of the operating table 1, and a clamping component 3 for improving the movement stability of the protection pipe is provided on one side of the cutting mechanism 2.
[0030] like Figure 2 , Figure 3 and Figure 6 As shown, the cutting mechanism 2 includes a servo motor 201 bolted to one side of the operating table 1. A lead screw 202 is coaxially mounted on the output end of the servo motor 201. Two stabilizing rods 203 are fixedly connected to one side of the operating table 1. A moving plate 204 is threadedly connected to the outer wall of the lead screw 202. The moving plate 204 is slidably connected to the outer wall of the two stabilizing rods 203. The moving plate 204 can be stably moved by the servo motor 201, the lead screw 202, and the stabilizing rods 203. A placement groove 205 is provided on one side of the moving plate 204. A toothed ring 206 is rotatably connected to the inner wall of the placement groove 205. A stabilizing plate 207 is bolted to the side of the moving plate 204 near the placement groove 205. 06 is rotatably connected to the inside of the stabilizing plate 207. A reduction motor 208 is bolted to one side of the stabilizing plate 207. A gear 209 is coaxially arranged at the output end of the reduction motor 208. The gear 209 meshes with the gear ring 206. A placement ring 210 is fixedly connected to the inner wall of the gear ring 206. By starting the reduction motor 208, the gear 209 can drive the gear ring 206 to rotate. Two first electric push rods 211 are arranged on one side of the placement ring 210. An arc plate 212 is arranged at the output end of each of the two first electric push rods 211. The two first electric push rods 211 and the arc plate 212 can clamp the protective tube to be cut. A cutting assembly 213 is arranged on the top of the operating table 1. In use, the MPP cable protection tube to be cut is placed in the placement ring 210, and the two first electric push rods 211 are activated to clamp the protection tube with the two arc plates 212. The servo motor 201 is activated to make the lead screw 202 rotate, which in turn drives the moving plate 204 to slide along the length of the two stabilizing rods 203, and slowly moves the clamped protection tube closer to the cutting assembly 213. During cutting, the reduction motor 208 is activated to make the gear 209 rotate, which in turn drives the gear ring 206 and the placement ring 210 to rotate, making the clamped protection tube rotate, reducing manual operation and improving work efficiency.
[0031] like Figure 2 , Figure 4 and Figure 5As shown, the cutting assembly 213 includes a support frame 21301 fixedly connected to the top of the operating table 1. A second electric push rod 21302 is provided on one side of the support frame 21301, and a mounting frame 21303 is provided at the bottom of the second electric push rod 21302. A first motor 21304 is bolted to one side of the mounting frame 21303. A cutting blade 21305 is coaxially provided at the output end of the first motor 21304. The height of the mounting frame 21303, the first motor 21304, and the cutting blade 21305 can be adjusted by the second electric push rod 21302 to facilitate the cutting of protective tubes of different sizes. An extension plate 21306 is fixedly connected to the side of the operating table 1 near the support frame 21301. A third electric push rod 21307 is provided on one side of the operating table 1. A sliding plate 21308 is provided at the output end of the third electric push rod 21307. The sliding plate 21308 slides along the length direction of the extension plate 21306. The sliding plate 21308 can be moved on the extension plate 21306 by the third electric push rod 21307, which facilitates the adjustment of the cutting length of the protective tube. The extension plate 21306 has an installation groove 21309 inside. The inner wall of the installation groove 21309 is fixedly connected to the installation frame 21310. The inner wall of the installation frame 21310 is provided with a pressure sensor 21311. The push plate 21312 is slidably connected inside the installation groove 21309. The side of the push plate 21312 near the installation groove 21309 is fixedly connected to the contact rod 21313. A spring 21314 is fixedly connected between the push plate 21312 and the installation frame 21310 and is located outside the contact rod 21313. A controller 21315 is provided on one side of the operating table 1. The servo motor 201, the geared motor 208, the second electric push rod 21302 and the first motor 21304 are all electrically connected to the controller 21315. The third electric actuator 21307 is activated, causing the sliding plate 21308 to slide along the length of the extension plate 21306. The distance between the side of the sliding plate 21308 with the push plate 21312 and the cutting blade 21305 is the cutting length of the protective tube. When the moving plate 204 moves the protective tube, one end of the protective tube will touch the push plate 21312, thereby squeezing the spring 21314, causing the contact rod 21313 to extend into the mounting frame 21310 and touch the pressure sensor 21311. At this time, the pressure sensor 21311 will transmit a signal to the controller 21315. The controller 21315 will activate the second electric actuator 21302, causing the mounting frame 21303 to descend, and simultaneously start the first motor 21304, causing the cutting blade 21305 to rotate at high speed to cut the rotating protective tube.
[0032] like Figure 3As shown, the clamping assembly 3 includes two fixed plates 301 fixedly connected to the side of the moving plate 204 away from the stabilizing plate 207. Each of the two fixed plates 301 has a telescopic cylinder 302 on its opposite side, and each telescopic cylinder 302 has a clamping plate 303 at its output end. When the protective tube moves with the moving plate 204, the two telescopic cylinders 302 are activated, causing the two clamping plates 303 to clamp the outer wall of the protective tube, improving the stability of the protective tube during movement. When cutting the protective tube, the two telescopic cylinders 302 are activated again to release the clamping of the protective tube, avoiding interference with subsequent rotational cutting of the protective tube.
[0033] like Figure 1 As shown, a bracket 4 is fixedly connected to one side of the operating table 1, and a placement block 5 is fixedly connected to the top of the bracket 4. A V-shaped groove 6 is provided inside the placement block 5. When cutting a long protective tube, the longer end of the protective tube can be placed in the V-shaped groove 6 in the placement block 5 to support the protective tube and improve its stability during cutting.
[0034] like Figure 2 As shown, a ramp 7 is fixedly connected to one side of the support frame 21301, and a panoramic camera 8 is installed on one side of the ramp 7. The panoramic camera 8 faces the cutting blade 21305 and is electrically connected to the controller 21315. The panoramic camera 8 can capture real-time images of the protective tube during cutting. When an external person attempts to touch the protective tube during cutting, the information will be transmitted to the controller 21315, which will promptly stop the first motor 21304 to prevent personnel from being injured by the cutting blade 21305 and reduce safety hazards.
[0035] like Figure 2 As shown, a guide rail 9 is fixedly connected to one side of the operating table 1. The guide rail 9 is located directly below the third electric actuator 21307. The bottom of the sliding plate 21308 extends into the interior of the guide rail 9 and is slidably connected to the guide rail 9. The guide rail 9 can improve the stability of the sliding plate 21308 when it moves.
[0036] like Figure 3 As shown, a stabilizing ring 10 is fixedly connected to the outer wall of the placement ring 210, and the stabilizing ring 10 is rotatably connected to the inside of the stabilizing plate 207. When the placement ring 210 rotates, it will synchronously drive the stabilizing ring 10 to rotate in the stabilizing plate 207, thereby improving the stability of the placement ring 210 during rotation.
[0037] Specifically, when using this automated cutting equipment for processing MPP cable protection pipes: place one end of the MPP cable protection pipe to be cut into the V-groove 6 in the placement block 5 (e.g., Figure 1(As shown); Start the servo motor 201 to move the moving plate 204 closer to the protective tube. At this time, start the two telescopic cylinders 302 to clamp the protective tube with the two clamping plates 303. By continuously rotating the servo motor 201 forward and backward, the protective tube can be slowly moved to the cutting blade 21305. Before cutting the protective tube, start the two telescopic cylinders 302 again to release the clamping of the protective tube. Then start the two first electric push rods 211 to clamp the protective tube with the two arc-shaped plates 212. Start the reduction motor 208 to rotate the gear 209, which in turn drives the gear ring 206 and the placement ring 210 to rotate, causing the clamped protective tube to rotate (as shown). Figure 2 , Figure 3 and Figure 6 (As shown); Activate the third electric actuator 21307 to make the sliding plate 21308 slide along the length of the extension plate 21306. The distance between the side of the sliding plate 21308 with the push plate 21312 and the cutting blade 21305 is the cutting length of the protective tube. When the moving plate 204 moves with the protective tube, one end of the protective tube will touch the push plate 21312, thereby squeezing the spring 21314, causing the contact rod 21313 to extend into the mounting frame 21310 and touch the pressure sensor 21311. At this time, the pressure sensor 21311 will transmit a signal to the controller 21315. The controller 21315 will activate the second electric actuator 21302 to lower the mounting frame 21303 and simultaneously start the first motor 21304 to make the cutting blade 21305 rotate at high speed to cut the rotating protective tube (as shown). Figure 2 , Figure 4 and Figure 5 (As shown).
[0038] All technical features in this embodiment can be freely combined according to actual needs.
[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
