Abstract
Description
Technical Field
[0001] This utility model relates to a corrugated pipe fixed-length cutting device. Background Technology
[0002] In related technologies, corrugated pipes are often used as conduits to protect cables. In the later stages of manufacturing corrugated pipes, they need to be cut to a set length. The cut of the corrugated pipe will form a sharp cutting edge. When the corrugated pipe is cut at the trough, the wire leading out from the end of the corrugated pipe is prone to rubbing against the cutting edge located at the trough, which will easily scratch the surface of the wire. Therefore, cutting the corrugated pipe at the crest can improve the above situation.
[0003] However, traditional cutting or circumferential cutting methods cannot guarantee that the cutting position is at the crest of the corrugated pipe. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of this invention is to provide a corrugated pipe length-cutting device that ensures the cutting position of the corrugated pipe is at the crest of the wave, thereby improving cutting accuracy and reducing the possibility of cutting the wire insulation.

[0006] A corrugated pipe length-cutting device according to an embodiment of the present utility model has at least the following beneficial effects:
[0007] The above-described corrugated pipe length-cutting equipment utilizes a transmission device to transport the corrugated pipe forward along its length. During this forward transport, the sensing unit senses and records the number of crests or troughs encountered. When the sensing unit detects a crest or trough, the corrugated pipe reaches the preset cutting length. At this point, the corresponding crest of the corrugated pipe is aligned with the cutting device. The clamping device clamps and positions the corrugated pipe, and then the cutting device cuts the corrugated pipe. This ensures that the cut of the corrugated pipe is located at the crest, which helps improve cutting accuracy and reduces the possibility of damaging the wire insulation.
[0008] In some embodiments of this utility model, the frame is provided with multiple guide sleeves arranged at intervals along the conveying direction of the corrugated pipe, and the inner diameter of the guide sleeves is adapted to the outer diameter of the corrugated pipe.

[0012] In some embodiments of this utility model, the widths of the first positioning groove and the second positioning groove are consistent with the width of the corrugated pipe crest. The first clamping block is provided with a first cutting groove with a side opening through the middle position of the width of one of the first positioning grooves. The second clamping block is provided with a second cutting groove with a side opening through the middle position of the width of the corresponding second positioning groove.

[0013] In some embodiments of this utility model, the first clamping block has a first semicircular cavity facing the second clamping block, and four first semi-annular protrusions are spaced apart on the inner peripheral wall of the first semicircular cavity. Two adjacent first semi-annular protrusions define a first positioning groove. The second clamping block has a second semicircular cavity opposite to the first semicircular cavity, and four second semi-annular protrusions are spaced apart on the inner peripheral wall of the second semicircular cavity. Two adjacent second semi-annular protrusions define a second positioning groove.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] See Figure 1 and Figure 2 This utility model discloses a corrugated pipe fixed-length cutting device, comprising: a frame 100, on which a transmission device 200 is provided to drive a corrugated pipe 10 to be conveyed along its length direction; a sensing unit 300, disposed on the frame 100, for sensing the crest 11 or trough 12 of the corrugated pipe 10; a clamping device 400 for positioning and clamping the corrugated pipe 10; and a cutting device 500, which cooperates with the clamping device 400 and is capable of cutting along the crest 11 of the corrugated pipe 10.
[0030] The above-described corrugated pipe 10 fixed-length cutting equipment uses a transmission device 200 to transport the corrugated pipe 10 forward along its length. During the forward transport of the corrugated pipe 10, the sensing unit 300 can sense and record the number of crests 11 or troughs 12 that it passes through. When the sensing unit 300 senses a crest 11 or trough 12, the corrugated pipe 10 reaches the preset cutting length. At this time, the corresponding crest 11 of the corrugated pipe 10 is aligned with the cutting device 500. The clamping device 400 clamps and positions the corrugated pipe 10, and then the cutting device 500 cuts the corrugated pipe 10. This ensures that the cut of the corrugated pipe 10 is at the crest 11, which helps to improve cutting accuracy and reduce the possibility of cutting the wire sheath.
[0031] In this embodiment, when the sensing unit 300 detects one crest 11 of the bellows 10, the other crest 11 of the bellows 10 is aligned with the cutting device 500. As the transmission device 200 moves the bellows 10 forward, the sensing unit 300 detects the number of crests 11 that have passed, thereby calculating the length of the bellows 10 that has been cut. When the preset value is reached, the clamping device 400 clamps and positions the bellows 10, and then the cutting device 500 cuts the bellows 10.
[0032] Of course, in other embodiments, it can be configured such that when the sensing unit 300 detects a trough 12 of the corrugated pipe 10, a crest 11 of the corrugated pipe 10 is aligned with the cutting device 500. As the transmission device 200 moves the corrugated pipe 10 forward, the sensing unit 300 detects the number of troughs 12 passed, thereby calculating the length of the corrugated pipe 10 being cut. Furthermore, the corrugated pipe 10 fixed-length cutting device with the above structure can also set the cutting position at the trough 12, which the user can set according to actual needs.
[0033] See Figure 1 and Figure 2 In some embodiments of this utility model, the frame 100 is provided with multiple guide sleeves 600 arranged at intervals along the conveying direction of the corrugated pipe 10. The inner diameter of the guide sleeves 600 is adapted to the outer diameter of the corrugated pipe 10. It can be understood that the arrangement of the guide sleeves 600 can ensure that the corrugated pipe 10 is conveyed in a straight line, avoiding bending or twisting of the corrugated pipe 10 and affecting the measurement accuracy and precision of the sensing unit 300, thereby ensuring that the length of the corrugated pipe 10 being cut and the cutting position are at the crest 11.
[0034] See Figure 1In some embodiments of this utility model, the transmission device 200 includes a first rotary conveyor belt 210 and a second rotary conveyor belt 220 located between two sections of the guide sleeve 600. The second rotary conveyor belt 220 and the first rotary conveyor belt 210 are vertically spaced to define a clamping gap for clamping the corrugated pipe 10. The second rotary conveyor belt 220 and the first rotary conveyor belt 210 rotate in opposite directions to drive the corrugated pipe 10 forward along the axial direction of the guide sleeve 600 in a preset direction. It can be understood that the corrugated pipe 10 is located in the clamping gap, causing the outer peripheral wall of the corrugated pipe 10 to contact the first rotary conveyor belt 210 and the second rotary conveyor belt 220. The first rotary conveyor belt 210 and the second rotary conveyor belt 220 rotate towards each other, using friction to drive the corrugated pipe 10 forward. Specifically, the first rotary conveyor belt 210 and the second rotary conveyor belt 220 have the same structure, both including multiple pulleys and a synchronous belt connected to the pulleys, and the pulleys are driven to rotate by a motor.
[0035] See Figure 2 In some embodiments of this utility model, the guide sleeve 600 has a through-hole groove 610 communicating with its inner cavity in its tube wall. The sensing unit 300 includes a laser sensor or photoelectric sensor with its emitting end facing the through-hole groove 610. It can be understood that the portions of the bellows 10 located at both ends of the through-hole groove 610 are constrained by the guide sleeve 600, which helps to ensure that the bellows 10 moves intelligently along the central axis of the guide sleeve 600. A portion of the bellows 10 is exposed from the through-hole groove 610, which helps to improve measurement accuracy. Taking the sensing unit 300 including a laser sensor as an example, the laser sensor emits a laser pulse. The laser is reflected by the outer peripheral wall of the bellows 10 and scattered in all directions. Some of the scattered light returns to the receiving end of the laser sensor, and the optical signal is converted into an electrical signal. After being filtered, amplified, and rectified by the corresponding circuit, an output signal is obtained, thereby calculating whether the detected position is the peak 11 or the trough 12.
[0036] See Figure 3 and Figure 4In some embodiments of this utility model, the clamping device 400 includes a first clamping block 410, a second clamping block 420, and a first driver 430. The first clamping block 410 is provided with at least one first positioning groove 411 corresponding to the crest portion 11 of the bellows 10. The second clamping block 420 is provided with second positioning grooves 421 that match the first positioning grooves 411 one by one. The first driver 430 drives the first clamping block 410 and the second clamping block 420 to move closer to each other so that the first positioning grooves 411 and the corresponding second positioning grooves 421 jointly clamp and position one crest portion 11 of the bellows 10. It can be understood that when the first driver 430 drives the first clamping block 410 and the second clamping block 420 to move closer to each other, the first positioning grooves 411 and the corresponding second positioning grooves 421 jointly clamp and position one crest portion 11 of the bellows 10, thereby accurately positioning and fixing the position of the bellows 10.
[0037] See Figure 3 and Figure 4 In some embodiments of this utility model, the widths of the first positioning groove 411 and the second positioning groove 421 are consistent with the width of the corrugated pipe 10 crest portion 11. The first clamping block 410 is provided with a first cutting groove 412 with a side opening through the middle position of the width of one of the first positioning grooves 411. The second clamping block 420 is provided with a second cutting groove 422 with a side opening through the middle position of the width of the corresponding second positioning groove 421. The cutting device 500 includes a cutting blade 510 and a second driver 520 that drives the cutting blade 510 into or out of the first cutting groove 412 and the second cutting groove 422. Understandably, after the first positioning groove 411 and the corresponding second positioning groove 421 clamp and position one crest portion 11 of the corrugated pipe 10, the apex of the crest portion 11 is directly opposite the first cutting groove 412 and the second cutting groove 422. The second driver 520 drives the cutting blade 510 to enter the first cutting groove 412 and the second cutting groove 422 from the side opening, thereby cutting the corrugated pipe 10 along the apex of the crest portion 11. Since the first cutting groove 412 and the second cutting groove 422 respectively penetrate the first positioning groove 411 and the second positioning groove 421, the crest portion 11 of the corrugated pipe 10 to be cut is completely limited, avoiding relative movement.
[0038] See Figure 4In some embodiments of this utility model, in order to further improve the positioning accuracy of the bellows 10 and alleviate the problem of relative displacement or deformation caused by limiting the positioning of only a single crest 11 of the bellows 10, the first clamping block 410 has a first semi-circular cavity facing the second clamping block 420. The inner peripheral wall of the first semi-circular cavity is provided with four first semi-annular protrusions 413 at intervals. Two adjacent first semi-annular protrusions 413 define a first positioning groove 411. The second clamping block 420 has a second semi-circular cavity opposite to the first semi-circular cavity. The inner peripheral wall of the second semi-circular cavity is provided with four second semi-annular protrusions 423 at intervals. Two adjacent second semi-annular protrusions 423 define a second positioning groove 421. The first slit groove 412 penetrates the first positioning groove 411 located in the middle, and the second slit groove 422 penetrates the second positioning groove 421 located in the middle.
[0039] See Figure 2 In some embodiments of this utility model, the second driver 520 is a motor, the motor having an output shaft connected to a mounting beam 530 orthogonal to it. Each end of the mounting beam 530 is equipped with a cutting blade 510, the cutting blade 510 having an arc-shaped cutting edge, and the two cutting blades 510 are symmetrical about the output shaft of the motor. It can be imagined that every 180° rotation of the mounting beam 530 driven by the motor results in one cutting blade 510 entering or leaving the first cutting groove 412 and the second cutting groove 422. The arc-shaped cutting edge helps to gradually increase the contact area between the cutting blade 510 and the bellows 10, contributing to the formation of a smooth cut.
[0040] In some embodiments of this utility model, in order to prevent the port of the corrugated pipe 10 from sticking to the cutting blade 510 and to ensure that the corrugated pipe 10 can be detached smoothly, both sides of the cutting blade 510 are coated with an anti-stick coating, wherein the anti-stick coating can be a Teflon coating or a titanium alloy coating.
[0041] In some embodiments of this utility model, the first clamping block 410 and the second clamping block 420 are both slidably and vertically disposed on the frame 100. The first driver 430 includes two lifting cylinders that drive the first clamping block 410 and the second clamping block 420 to move up and down respectively. At least one of the lifting cylinders is provided with a stroke detector. The stroke detector, the lifting cylinder, and the transmission device 200 are all electrically connected to the control module. It should be noted that when the two lifting cylinders drive the first clamping block 410 and the second clamping block 420 to move closer to each other, if the corrugated portion 11 of the bellows 10 is not clamped by the first positioning groove 411 and the second positioning groove 421, that is, the position of the bellows 10 in the clamping device 400 is deviated, the movement stroke of the lifting cylinders has not reached the set stroke. At this time, the control module controls the two lifting cylinders to drive the first clamping block 410 and the second clamping block 420 to move away from each other, and then controls the transmission device 200 to drive the bellows 10 forward a distance less than the width of one corrugated portion 11. Then the two lifting cylinders drive the first clamping block 410 and the second clamping block 420 to move closer to each other again, thereby automatically correcting the position of the bellows 10, and finally ensuring that it can be cut along the corrugated portion 11 of the bellows 10.
[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
