[0037] Heat shrink tubing is produced through an extrusion process. In the initial stage of molding extrusion (i.e., from the time the material comes out of the mold to the time it enters the traction stage), the screw extruder rotates to provide continuous pressure to the molten material as extrusion power. The extruder head extrude the tube, and the tube is cooled through a water tank under the action of a traction machine until it is transported to the next section for fixed-length cutting. Since the tube is always in motion, general cutting equipment often has the problem of uneven cuts, and secondary pipe repair is often required, resulting in waste of raw materials and manpower. In addition, heat shrink tubing has a variety of specifications. A tube rotary cutting device is designed for this situation.

[0038] Please refer to Figures 1 to 6 The utility model proposes a pipe peeling device 100, comprising a base 10, a positioning mechanism 20 and a peeling mechanism 30. The positioning mechanism 20 is arranged on the base 10, and is provided with a positioning channel 20A for the pipe 70 to pass through. The positioning mechanism 20 comprises an adjustment disk 21 and a positioning disk 21 coaxially connected to the adjustment disk 21. The adjustment disk 21 is provided with a plurality of guide grooves 211. Positioning components 23 that can slide radially on the positioning disk 21 are slidably arranged in the guide grooves 211. At least part of the positioning components 23 are located in the positioning channel 20A to adjust the size of the positioning channel 20A. The peeling mechanism 30 is coaxially connected to the positioning mechanism 20 and is arranged on the base 10. The peeling mechanism 30 is provided with a peeling channel 30A for the tube 60 to pass through. The peeling channel 30A is connected to the positioning channel 20A. The peeling mechanism 30 includes a cutter assembly 31 and a first gear 32. The cutter assembly 31 is extended along the radial direction of the first gear 32 to rotate around the tube 70 to cut the tube 70; wherein, when the cutter assembly 31 cuts the tube 70, at least part of the cutter assembly 31 is located in the peeling channel 30A.

[0039] The tube peeling device 100 of the utility model includes a base 10, a positioning mechanism 20 and a peeling mechanism 30. The size of the positioning channel 20A is adjusted by the positioning component 23 of the positioning mechanism 20, so that the tubes 70 of different diameters can be clamped to achieve subsequent cutting. At the same time, the first gear 32 of the peeling mechanism 30 is used to realize the rotation of the cutter component 31 around the tube 70. Furthermore, the cutter component 31 is extended along the radial direction of the first gear 32 to realize the advance and retreat of the cutter component 31, and then the cutter component 31 is realized to rotate around the tube 70 to cut the tube 70, thereby realizing the flatness of the incision when the tube peeling device 100 cuts the tube 70, and improving the versatility of the tube peeling device 100.

[0040] It is understandable that since the tube 70 is in motion from the previous station to the tube peeling device 100, when the cutter assembly 31 cuts the tube 70, the positioning mechanism 20, the peeling mechanism 30 and the tube 70 have relative movement in the X-axis direction (the tube forward direction is defined as the X-axis direction), the cut will become uneven when the cutter assembly 31 cuts the tube 70, and even require secondary pipe repair. In order to solve this problem, the tube peeling device 100 is also provided with a frame 60, and the base 10 is slidably arranged on the frame 60. When the positioning mechanism 20 positions the tube 70, the base 10 and the tube 70 have the same movement speed in the direction of the tube's travel, so that when the cutter assembly 31 cuts the tube 70, the peeling mechanism 30 and the tube 70 are relatively stationary in the direction of the tube's travel. In this embodiment, please refer to Figure 1 and Figure 2 The base 10 is formed by a horizontal steel plate and a vertical steel plate arranged vertically, and the frame 60 is a cuboid with a horizontal platform. The horizontal steel plate of the base 10 and the horizontal platform of the frame 60 are slidably connected by sliders and rails. Of course, the base 10 and the frame 60 can also be other structures as long as they can meet the requirements of installing sliding components on both. As for the sliding connection between the two, it can also be a connection method of pulleys and rails, which is not limited here, as long as the relative sliding of the two can be achieved.

[0041] It can be understood that a through hole is opened in the middle of the vertical steel plate of the base 10 for the pipe 70 to pass through, and the positioning mechanism 20 is installed on the inlet side of the through hole of the vertical steel plate through a bearing, that is, the pipe 70 enters the through hole of the vertical steel plate, and the rotary cutting mechanism 30 is installed on the outlet side of the through hole of the vertical steel plate through a bearing, that is, the pipe 70 leaves the through hole of the vertical steel plate, so as to realize the coaxial connection between the positioning mechanism 20 and the rotary cutting mechanism 30. The pipe 70 is produced by an extrusion process. After coming out of the extruder, it first passes through the positioning channel 20A of the positioning mechanism 20, and then passes through the peeling channel 30A of the peeling mechanism 30. The positioning mechanism 20 clamps the pipe 70 through the positioning component 23. At this time, the moving pipe 70 drives the positioning component 23 to move along the X-axis direction, and the positioning component 23 drives the base 10 to move forward along the X-axis. Therefore, the pipe 70 and the positioning mechanism 20 and the peeling mechanism 30 installed on the base 10 are relatively stationary in the X-axis direction. After being pushed to the set position, the cutter component 31 advances. At the same time, the cutter component 31 rotates around the pipe 70 driven by the first gear 32 to complete the rotary cutting to ensure the end surface flatness and length stability of the cut pipe 4. In order to ensure the reset of the base 10, a push block and a cylinder seat can be installed on the bottom of the horizontal steel plate of the base 10 away from the side of the pipe 10, a cylinder is fixedly installed on the cylinder seat, and the output end of the cylinder is connected to the push block, and the cylinder drives the push block to reset, so as to realize the reset of the base 10. Of course, a tension spring can also be installed between the base 10 and the upstream station for reset, and other methods can also be used, which are not limited here.

[0042] To further improve the rotatability of the cutter assembly 31 around the pipe 70, in one embodiment, in combination with reference Figure 2 and Figure 4 The peeling mechanism 30 also includes a second gear 33 and a first driving member 34. The second gear 33 is disposed on the base 10, connected to the output end of the first driving member 34, and meshes with the first gear 32 for transmission. The first driving member 34 drives the second gear 33 to rotate, drives the first gear 32 to rotate, and then drives the cutter assembly 31 to rotate around the pipe 70.

[0043] In order to realize the advance and retreat of the cutter assembly 31, in one embodiment, in combination with reference to Figure 5 The cutter assembly 31 includes a cutter 311, a cutter seat 312 and a cutter cylinder 313. The cutter 311 is slidably arranged on the cutter seat 312 along the radial direction of the first gear 32. The cutter seat 312 is connected to the output end of the cutter cylinder 313 and is arranged on the first gear 32. The cutter cylinder 313 is arranged on the first gear 32.

[0044] It can be understood that in order to facilitate the installation and cutting of the cutter assembly 31, the cutter assembly 31 also includes a cutter cylinder seat 314, a cutter assembly bottom plate 315 and a cutter assembly mounting seat 316. The cutter assembly mounting seat 316 is fixedly mounted on the first gear 32, the cutter assembly bottom plate 315 is fixedly mounted on the cutter assembly mounting seat 316, the cutter cylinder seat 314 is fixedly mounted on the cutter assembly bottom plate 315, the cutter cylinder 313 is arranged on the cutter cylinder seat 314, the cutter seat 312 is connected to the output end of the cutter cylinder 313, and the cutter 311 is slidably arranged on the cutter seat 312 along the radial direction of the first gear 32. In this way, under the drive of the cutter cylinder 313, the cutter 311 can be advanced and retreated along the radial direction of the first gear 32, so that the cutter assembly 31 can cut the pipe 70.

[0045] In order to prevent the cutter assembly 31 from rotating around the pipe 70 and causing the wires to get tangled due to the cutter cylinder 313 controlling the advance and retraction of the cutter 311, the first drive member 34 drives the cutter assembly 31 to reciprocate around the pipe 70 to cut the pipe 70. The first drive member can be a drive structure such as a cylinder, a small linear motor, or an electric push rod. As long as the cutter assembly 31 can reciprocate around the pipe 70, there is no limitation on this.

[0046] In order to further improve the efficiency of the cutter 311 in cutting the pipe 70, the cutter assembly 31 is provided with n, n ≥ 1, and the first driving member 34 drives the cutter assembly 31 to reciprocate around the pipe 70 to cut the pipe 70, wherein the reciprocating angle is ≥ 360° / n. It can be understood that two cutter assemblies 31 can be provided, so that when the first driving member 34 drives the cutter assembly 31 to reciprocate around the pipe 70 to cut the pipe 70, the reciprocating angle is ≥ 180°, so that the reciprocating rotation of the first gear 32 can prevent the cutter cylinder 313 from getting tangled with wires when the cutter cylinder 313 follows the first gear 32 to rotate unidirectionally and continuously.

[0047] In order to improve the clamping force on the pipe 70, in one embodiment, in combination with reference Figure 3 The guide grooves 211 are arranged in an array along the circumference of the adjustment disk 21 as arc-shaped guide grooves that gradually move away from the center of the adjustment disk 21 .

[0048] In order to further improve the clamping force on the pipe 70, in one embodiment, in combination with reference Figure 3 The positioning assembly 23 includes a plurality of adjustment rods 231 and a plurality of clamping blocks 232. The adjustment rods 231 are at least partially slidably disposed in the guide grooves 211 and are fixedly connected to the clamping blocks 232. The positioning plate 22 is provided with a plurality of receiving grooves for accommodating the clamping blocks 232. The clamping blocks 232 slide in the receiving grooves to adjust the size of the positioning channel 20A.

[0049] It can be understood that the guide groove 211 is arranged along the circumferential array of the adjustment disk 21 as an arc-shaped guide groove gradually moving away from the center of the adjustment disk 21. Further, by vertically installing the downward pressure cylinder 24 on the base 10, the downward pressure cylinder 24 can be installed on the vertical steel plate of the base 10, and the adjustment disk 21 is fixedly connected to the output end of the downward pressure cylinder 24. Thus, the downward pressure cylinder 24 controls the rotation angle of the adjustment disk 21 around the pipe 70, thereby controlling the movement distance of part of the adjustment rod 231 in the guide groove 211. In this way, the movement distance of the clamping block 232 fixedly connected to the adjustment rod 231 in the receiving groove on the positioning disk 22 is controlled, thereby adjusting the size of the space enclosed by a number of clamping blocks 232, thereby realizing the adjustment of the size of the positioning channel 20A, so as to adapt to pipes 70 of different sizes. In order to limit the space enclosed by the clamping blocks 232 from being too small, a positioning screw 25 can also be provided on the base 10. The positioning screw 25 is arranged adjacent to the downward-pressing cylinder 24 and parallel to the output end of the downward-pressing cylinder 24. It can be arranged on the vertical steel plate of the base 10 together with the downward-pressing cylinder 24. Furthermore, a blocking block 26 is provided on the positioning screw 25 to limit the movement stroke of the output end of the downward-pressing cylinder 24 when it moves downward, to avoid the adjustment rod 231 from moving too far in the guide groove 211, which would make the space enclosed by the clamping blocks 232 too small, causing the clamping blocks 232 to crush the pipe 70, thereby affecting the expansion of the pipe 70 in the subsequent expansion process. The blocking block 26 can slide freely on the positioning screw 25 to further adjust the movement stroke of the output end of the downward-pressing cylinder 24 when it moves downward.

[0050] In order to improve the accuracy of the pipe 70 entering the positioning mechanism 20, in one embodiment, in combination with reference Figure 1 The pipe peeling equipment 100 also includes a guide mechanism 40, which is arranged on the base 10 and located upstream of the positioning mechanism 20, and includes two first guide cylinders 41 that are spaced apart and extend in the vertical direction, and a second guide cylinder 42 that is perpendicular to the two first guide cylinders 41. The second guide cylinder 42 and the two first guide cylinders 41 enclose a guide channel for the pipe 70 to pass through, and the guide channel is connected to the positioning channel 20A and the peeling channel 30A in sequence.

[0051] It can be understood that the guide mechanism 40, the positioning mechanism 20, and the rotary cutting mechanism 30 are arranged in sequence along the traveling direction of the tube 70. The tube 70 is produced by an extrusion process. After coming out of the extruder, it first passes through the guide channel of the guide mechanism 40, and then enters the positioning channel 20A of the positioning mechanism 20. The size of the positioning channel 20A is adjusted by the positioning component 23, so that the tubes 70 of different diameters can be clamped, and finally enter the rotary cutting mechanism 30. The first gear 32 of the rotary cutting mechanism 30 is used to realize the rotation of the cutter component 31 around the tube 70. Furthermore, the cutter component 31 is extended along the radial direction of the first gear 33, so that the cutter component 31 can be advanced and retreated, and then the cutter component 31 can be rotated around the tube 70 to cut the tube 70.

[0052] In order to realize the blanking function, in one embodiment, in combination with reference to Figure 6 The pipe peeling equipment 100 also includes a feeding mechanism 50, which is arranged on the base 10 and located downstream of the peeling mechanism 30, and includes a feeding cross bar 51, a feeding column 52 and a feeding plate 53. The feeding cross bar 51 is fixedly connected to the base 10, the feeding column 52 is vertically slidably arranged relative to the feeding cross bar 51, and the feeding plate 53 is connected to the feeding column 52.

[0053] It can be understood that the vertical sliding arrangement of the material discharge column 52 relative to the material discharge cross bar 51 can meet the requirements of material discharge of pipes 70 of different lengths. When the rotary cutting mechanism 30 completes the cutting of the pipe 70, the material discharge plate 53 can rotate relative to the material discharge column 52 to achieve the material discharge function. A guide mechanism 40 can also be provided between the rotary cutting mechanism 30 and the material discharge mechanism 50 so that the pipe 70 does not deviate when entering the material discharge mechanism 50 from the rotary cutting mechanism 30, which is more accurate.

[0054] In order to further realize the automatic unloading function, in one embodiment, in combination with reference to Figure 6 The unloading mechanism 50 also includes a photoelectric sensor 54 disposed on the unloading plate 53. The photoelectric sensor 54 is used to detect whether there is a pipe 70 on the unloading plate 53. When there is a pipe 70, the rotary cutting mechanism 30 cuts the pipe 70, and the unloading plate 53 rotates relative to the unloading column 52 to complete the unloading.

[0055] The utility model also proposes a pipe extrusion production line (not shown), which includes an extruder (not shown) and a pipe peeling device 100. The specific structure of the pipe peeling device 100 refers to the above embodiment. Since the pipe extrusion production line adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the pipe peeling device is arranged downstream of the extruder.

[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
