Description

[Technical field]

[0001] The utility model belongs to the technical field of pipe peeling equipment, in particular to a nylon pipe peeling device. [Background technology]

[0002] Due to the new requirements of automobile OEMs for fuel lines, they hope to increase the impact resistance requirements of the oil pipes. Therefore, it is necessary to add a layer of TPE sheath to the outer layer of the nylon tube. This TPE sheath is tightly coated on the outer layer of the nylon tube. However, during use, the TPE sheath at both ends of the nylon tube needs to be removed by about 25 to 35 mm at the quick connector connection. Since the nylon tube is hollow, it is easy to deform when clamped, and the thickness of the TPE coating is uneven, which makes it very difficult to remove the TPE at both ends of the nylon tube, and the removal is not clean or the surface of the nylon tube is damaged.

[0003] Chinese patent publication number CN221518007U discloses a pipe peeling device and a double-head peeling equipment thereof. The pipe peeling device includes a clamping mechanism, a cutting mechanism and a peeling mechanism which are arranged in sequence along the axial direction of the pipe. The clamping mechanism clamps the pipe, the cutting mechanism cuts the pipe skin on the outer periphery of the pipe, and the peeling mechanism clamps the cut pipe skin and pulls it backward to separate the pipe skin from the surface of the pipe, thereby completing the pipe peeling action. The above scheme can be used on hard pipes or solid pipes. The clamping mechanism will not deform when clamping the pipe. Since the nylon tube is hollow, if the above clamping mechanism is directly used, the nylon tube will be deformed, resulting in unclean peeling or damage to the surface of the nylon tube.

[0004] Therefore, it is necessary to provide a nylon tube peeling device to solve the above-mentioned technical problems. [Utility Model Content]

Detailed Embodiment

[0033] Please refer to Figures 1-4 , this embodiment is a nylon tube peeling device. The nylon tube peeling device 100 includes a frame 1, a clamping mechanism 2 for clamping the nylon tube arranged in sequence along the axial direction of the nylon tube, a cutting mechanism 3 for cutting off the sheath layer at the end of the nylon tube, and a peeling mechanism 4 for making the cut sheath layer fall off from the end of the nylon tube. The cutting mechanism 3 and the peeling mechanism 4 are jointly arranged on a first support plate 5. A first motor 6 for driving the first support plate 5 to move closer to or away from the clamping mechanism 2 is arranged on the frame 1. A support assembly 7 that is inserted into the nylon tube from the end to be peeled of the nylon tube and supports inside the hollow nylon tube is arranged on the first support plate 5. A waste receiving box 8 is arranged below the cutting mechanism 3, and a positioning mechanism 9 for positioning the position of the end of the nylon tube is arranged above it.

[0034] The clamping mechanism 2 includes a fixed clamping block 21, a movable clamping block 22 arranged opposite to the fixed clamping block 21 left and right, and a first cylinder 23 for driving the movable clamping block 22 to approach or move away from the fixed clamping block 21. First clamping grooves that are shaped like the nylon tube are arranged on the opposite sides of the fixed clamping block 21 and the movable clamping block 22. When the first cylinder 23 drives the movable clamping block 22 to approach the fixed clamping block 21, the two first clamping grooves are butted left and right and jointly clamp the outer circumference of the nylon tube, realizing the clamping action on the nylon tube.

[0035] A guiding cylinder 25 for allowing the nylon tube to smoothly enter the first clamping groove is also arranged on one side of the fixed clamping block 21 and the movable clamping block 22.

[0036] The peeling mechanism 4 includes two second cylinders 41 arranged opposite to each other left and right on the first support plate 5, a pair of moving plates 42 driven by the second cylinders 41 to move away from or close to each other, and clamping jigs 43 fixed on the opposite inner sides of the moving plates 42 and clamping the outer circumference of the nylon tube. Second clamping grooves that are shaped like the nylon tube are arranged on the opposite sides of the clamping jigs 43. A barb structure for clamping the outer sheath layer of the nylon tube is arranged on the second clamping grooves. The barb structure is inserted into the sheath layer of the nylon tube that needs to be removed, so that when the first motor 6 drives the first support plate 5 to pull forward, the sheath layer can smoothly fall off from the nylon tube. A limiting plate 51 for limiting the movement of the moving plates 42 is also arranged on the first support plate 5. When the moving plates 42 drive the clamping jigs 43 to clamp the nylon tube and to prevent the clamping jigs 43 from over-clamping the nylon tube and damaging it, the limiting plate 51 is provided to limit the movement of the moving plates 42.

[0037] The cutting mechanism 3 includes two third cylinders 31 respectively arranged on the opposite outer sides of a pair of moving plates 42, a moving mounting block 32 driven by the third cylinders 31 to move away from or close to each other, and a cutting knife 33 mounted on the moving mounting block 32. The cutting knife 33 is located at the rear side of the clamping fixture 43 and close to the clamping mechanism 2. When the two third cylinders 31 respectively drive the two moving mounting blocks 32 to move close to each other, the two cutting knives 33 face each other and simultaneously cut into the sheath layer of the nylon tube, completing the cutting action of the sheath layer on the surface of the nylon tube.

[0038] The support assembly 7 includes a support seat 71 fixed on the first support plate 5 and a support cylinder 72 fixed on the support seat 71 and conforming to the inner diameter size of the nylon tube. A nozzle for blowing off the sheath layer is arranged on the support seat 71. After the cut sheath layer is pulled off by driving the clamping fixture 43 to move by the first motor, the pulled-off sheath layer is sleeved on the end of the support cylinder 72 and directly falls into the waste receiving box 8 after being blown off by the nozzle; the support cylinder 72 is located between the two clamping fixtures 43. When the nylon tube is clamped on the clamping mechanism 2, the axis of the support cylinder 72 is on the same horizontal line as the axis of the nylon tube. The support cylinder 72 conforms to the inner diameter size of the nylon tube. When the first motor 6 drives the first support plate 5 to drive the support cylinder 72 to extend from one end of the nylon tube to be peeled into the nylon tube, the nylon tube is supported inside by the arranged support cylinder 72. When the peeling mechanism 4 and the cutting mechanism 3 act on the outer periphery of the nylon tube, the nylon tube will not be deformed, avoiding incomplete peeling or damage to the surface layer of the nylon tube.

[0039] The positioning mechanism 9 includes a baffle 91 for blocking the end of the nylon tube, a lifting plate 92 for mounting the baffle 91, a fourth cylinder 93 for driving the lifting plate 92 to move up and down, a mounting frame 94 for mounting the fourth cylinder 93, and a driving module 95 for driving the mounting frame 94 to move back and forth. A sensor 96 for detecting the forward extension of the nylon tube in place is arranged on the lifting plate 92, and the baffle 91 is located above the support cylinder 72.

[0040] The arranged driving module 95 can drive the mounting frame 94 to move back and forth, which can adapt to different peeling lengths, has better versatility, high adaptability, and low production cost.

[0041] When applying a nylon tube peeling device 100 provided by the present solution, according to the length of the sheath layer to be removed from the outer periphery of the nylon tube, the driving module 95 can drive the mounting bracket 94 to move back and forth to adjust to an appropriate position. The fourth cylinder 93 drives the lifting frame 92 to descend, driving the baffle 91 to descend in place. One end of the nylon tube to be peeled is inserted into the first card slot from the guiding cylinder 25 until the end of the nylon tube abuts against the baffle 91. At the same time, the sensor 96 senses that the nylon tube is inserted in place. The first cylinder 23 drives the movable clamping block 22 to move towards the fixed clamping block 21 side. The two first card slots are butted left and right and jointly clamped on the outer periphery of the nylon tube to realize the clamping of the nylon tube. At the same time, the fourth cylinder 93 drives the lifting frame 92 to rise, driving the baffle 91 to rise in place. The first motor 6 drives the first support plate 5 to move, driving the cutting mechanism 3, the peeling mechanism 4 and the support assembly 7 to move towards the clamping mechanism 2 side until the support cylinder 72 of the support assembly 7 is inserted into the inside of the nylon tube from the end of the nylon tube. After the support cylinder 72 is inserted in place, the two second cylinders 41 drive the two moving plates 42 to approach each other at the same time, so that the clamping jig 43 clamps on the outer periphery of the nylon tube, and the thorn structure is inserted into the sheath layer of the nylon tube to be removed. At the same time, the moving plate 42 drives the cutting knives 33 of the cutting mechanism 3 to approach each other and surround the outer periphery of the nylon tube. The third cylinder 31 drives the moving mounting block 32 to drive the cutting knives 33 to approach relatively and simultaneously cut into the sheath layer of the nylon tube to complete the cutting action of the surface sheath layer of the nylon tube. When the sheath layer is about to be cut off, the third cylinder 31 drives the moving mounting block 32 to drive the cutting knives 33 to move away relatively. The first motor 6 drives the first support plate 5 to move, driving the cutting mechanism 3, the peeling mechanism 4 and the support assembly 7 to move away from the clamping mechanism 2, so that the clamping jig 43 clamps the sheath layer and moves until the sheath layer completely detaches from the end of the nylon tube. The two second cylinders 41 drive the two moving plates 42 to move away from each other at the same time, and the two clamping jigs 43 are loosened. A cut section of the sheath layer is sleeved on the end of the support cylinder 72. The provided air nozzle blows air towards the end of the support cylinder 72 to blow off a cut section of the sheath layer, so that the sheath layer falls into the waste receiving box 8 below to complete the peeling of the end of the nylon tube.

[0042] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
