Mpp cable protection pipe cutting device

Abstract

This utility model discloses an MPP cable protection tube cutting device, including a support mechanism, a pressing mechanism, and a cutting mechanism. The support mechanism includes a support block, a front plate fixedly installed on one side of the support block, a guide roller fixedly installed on the front plate, a side support rod fixedly installed on the outside of the support block, and a top support fixedly installed on the top of the side support rod. The pressing mechanism includes a sliding block slidably connected to the inside of the top support, a limiting slide rod movably sleeved with the sliding block, and a drive motor fixedly installed at the middle of the top of the sliding block. In this utility model, the pressing gear presses down on the protection tube, so that the protection tube is stably placed between the blade and the rotating wheel. At the same time, the roller limits the side of the protection tube, which ensures that the protection tube is stably placed between the blade and the rotating wheel. Thus, the rotation of the rotating wheel drives the protection tube to rotate and be cut by the blade, greatly improving the cutting quality and enhancing the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of pipe cutting equipment technology, specifically to an MPP cable protection pipe cutting device. Background Technology

[0002] MPP cable protection pipes use modified polypropylene as the main raw material, which has the characteristics of high temperature resistance and external pressure resistance. They are suitable for high voltage power transmission cable ducts above 10KV. However, during the processing of MPP cable protection pipes, it is often necessary to cut the MPP power cable protection pipes to a specified length. Existing MPP cable protection pipe cutting operations require fixing the protection pipe, but the fixing structure is often difficult to rotate. Therefore, the cutting method is to cut from bottom to top. This cutting method requires strong pressure, and the cutting process can also cause deformation of the protection pipe, resulting in an uneven cut. To address this, an MPP cable protection pipe cutting device is proposed. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] An MPP cable protection pipe cutting device includes a support mechanism, a pressing mechanism, and a cutting mechanism. The support mechanism includes a support block, a front plate fixedly installed on one side of the support block, a guide roller fixedly installed on the front plate, a side support rod fixedly installed on the outside of the support block, and a top support fixedly installed on the top of the side support rod. The pressing mechanism includes a sliding block slidably connected to the inside of the top support, a limiting slide rod movably sleeved with the sliding block, a drive motor fixedly installed at the middle of the top of the sliding block, a screw fixedly connected to the output end of the drive motor, a threaded sleeve threadedly connected to the screw, a pressing gear rotatably connected to the middle of the bottom of the sliding block, a telescopic rod engaged on both sides of the bottom of the sliding block, and a roller rotatably connected to the bottom of the telescopic rod. The cutting mechanism includes a blade rotatably connected to the inside of the support block, a flipping wheel connected to the inside of another support block and corresponding to the blade, a protective shell fixedly installed on the other side of the support block, a rotary motor fixedly installed on the protective shell, a transmission gear connected to the output end of the rotary motor, and a transmission toothed belt meshing with the transmission gear.

[0006] Preferably, there are two transmission gears, which are fixedly connected to the central shafts of the blade and the turning wheel, respectively.

[0007] Preferably, the top of the threaded sleeve is fixedly connected to the inner side of the top bracket.

[0008] Preferably, a spring is provided at the connection between the sliding block and the telescopic rod, and there are two sets of telescopic rods.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0012] In this invention, a downward-pressing gear presses down the protective tube, ensuring that the protective tube is stably positioned between the blade and the rotating wheel. At the same time, a roller limits the side of the protective tube, thus ensuring that the protective tube is stably positioned between the blade and the rotating wheel.

[0021] Example:

[0022] Combination Figure 1-2As shown, this utility model provides an MPP cable protection pipe cutting device, including a support mechanism, a pressing mechanism, and a cutting mechanism. The support mechanism includes a support block 110, a front plate 120 fixedly installed on one side of the support block 110, a guide roller 130 fixedly installed on the front plate 120, a side support rod 140 fixedly installed on the outside of the support block 110, and a top support 150 fixedly installed on the top of the side support rod 140. The pressing mechanism includes a sliding block 210 slidably connected to the inside of the top support 150, a limiting slide rod 220 movably sleeved with the sliding block 210, a drive motor 230 fixedly installed at the middle of the top of the sliding block 210, a screw 240 fixedly connected to the output end of the drive motor 230, a threaded sleeve 250 threadedly connected to the screw 240, a pressing gear 260 rotatably connected to the middle of the bottom end of the sliding block 210, a telescopic rod 270 clamped to both sides of the bottom end of the sliding block 210, and a roller 280 rotatably connected to the bottom end of the telescopic rod 270. The top is fixedly connected to the inner side of the top bracket 150. A spring is provided at the connection between the sliding block 210 and the telescopic rod 270. There are two sets of telescopic rods 270. The cutting mechanism includes a blade 310 rotatably connected to the inner side of the support block 110, a flipping wheel 320 connected to the inner side of another support block 110 and corresponding to the blade 310, a protective shell 350 fixedly installed on the other side of the support block 110, a rotary motor 360 fixedly installed on the protective shell 350, a transmission gear 330 connected to the output end of the rotary motor 360, and a transmission toothed belt 340 meshing with the transmission gear 330. There are two transmission gears 330. The two transmission gears 330 are fixedly connected to the central shafts of the blade 310 and the flipping wheel 320, respectively.

[0023] Specifically, by setting two sets of support blocks 110 to install blades 310 and rotating wheels 320 respectively, protective tubes of different sizes can be placed between the support blocks 110. The rotating wheels 320 drive them to rotate, and the blades 310 are used to cut them, which effectively ensures the uniformity of the cutting and improves the practicality of the device.

[0024] The working principle and usage process of this utility model are as follows: First, install the device in the required position and start the device.

With the help of the threaded sleeve 250, the sliding block 210 can be driven to descend or rise until the roller 280 and the pressing gear 260 abut against the protective tube. Start the rotary motor 360 to drive the transmission gear 330 to rotate, so that the blade 310 starts to cut. The rotating wheel 320 drives the protective tube to rotate. Finally, the cut protective tube can be removed.
