Description

Technical Field

[0001] This invention relates to the field of cable tie machine technology, specifically to an automatic cable tie locking and cutting machine. Background Technology

[0002] In the stator coils of low-power motors, some electronic components, such as resistors, diodes, and thermal protectors, are secured with plastic cable ties to ensure reliable positioning. The manufacturing process typically involves manual tightening followed by cutting. However, inconsistent tightening force by operators can lead to uneven tightening, causing friction between the components during motor armature operation and resulting in defective products. Existing cable tie cutting devices vary in structure and effectiveness, necessitating a solution to address these technical problems.

[0003] As described in patent document CN201721664U, this device features an intermediate support with an angle steel structure on the working platform. The side of the angle steel of this intermediate support perpendicular to the working platform is fixed to the piston rod of the locking cylinder. A cutting cylinder with a cutter is located on one side of the pressing cylinder, and a stator is located on the other side of the pressing cylinder. This avoids the quality defects of manual stator coil cable tie locking, ensures consistent cable tie locking force, and automatically cuts the cable ties. It is easy to operate, reduces labor intensity, and improves production efficiency. However, during operation, the cut cable tie waste tends to accumulate at the cutting equipment, causing jamming and affecting the efficiency of subsequent cable tie locking. Summary of the Invention

[0004] The technical problem solved by this solution is:

[0005] (1) How to set up a winding mechanism, and drive the support plate to move by extending and retracting the extension end of the feeding cylinder. Due to inertia, the cable tie and the cut cable tie waste are separated. In this process, the cable tie is shaken by extending and retracting the feeding cylinder, so that the cable tie and the cable tie waste are separated, thus avoiding affecting the subsequent cable tie locking operation.

[0006] (2) How to set up a vibration mechanism so that when the extension end of the feeding cylinder extends, the gear is driven to rotate through the rack and pinion, and then the extension end of the feeding cylinder is reset, so that the rubber rod drives the impact hammer to slightly impact the guide channel, causing the guide channel to vibrate and shake off the cable tie waste accumulated inside, so as to avoid the cable tie waste affecting the efficiency of subsequent cable tie locking.

[0007] The objective of this invention can be achieved through the following technical solution: an automatic cable tie locking and cutting machine, including a base, a slider is slidably arranged on one side of the top of the base via a guide rail, a support plate is fixedly installed on the top of the slider, a feeding cylinder for driving the slider to move is also provided on the base, a winding mechanism for tightening the cable tie is provided on one side of the top of the support plate, and a vibration mechanism for striking the winding mechanism is provided in the middle of the base.

[0008] The winding mechanism includes a mounting base fixedly connected to a support plate, a connecting block fixedly mounted on the mounting base, a guide groove inside the connecting block, a tape inlet at one end of the connecting block, the tape inlet communicating with the guide groove, a rotating column movably inserted on the connecting block, the rotating column being arranged horizontally, and a cutting groove at one end of the rotating column being arranged perpendicularly to the tape inlet.

[0009] A further technical improvement of the present invention is as follows: a guide channel for recycling cable tie waste is provided on one side of the mounting base, and the input end of the guide channel is connected to the output end of the guide groove; the cable tie is manually inserted into the inlet, at which time the extension end of the cutting cylinder is in its shortest state, the cable tie enters the guide groove through the cutting groove and contacts the winding shaft, the cable tie is tightened by rotating the winding shaft, and then the extension end of the cutting cylinder extends, causing the connecting rod to drive the rotating column to rotate, so that the cutting groove cuts the cable tie, the extension end of the cutting cylinder returns to its original position, and the extension and retraction of the extension end of the feeding cylinder drives the support plate to move. Due to inertia, the cable tie and the cut cable tie waste are separated. This process tightens the cable tie by winding the shaft to avoid insufficient cable tie tightening. At the same time, the extension and retraction of the feeding cylinder causes the cable tie to shake, so that the cable tie and the cable tie waste are separated, avoiding affecting the subsequent cable tie tightening operation.

[0010] A further technical improvement of the present invention is that: the vibration mechanism includes a rotating seat fixedly connected to the base, a rubber rod rotatably mounted on the rotating seat via a pin, an impact hammer fixedly mounted on the top of the rubber rod, the impact hammer contacting the guide channel, a gear fixedly mounted on one end of the pin, an mounting block fixedly mounted on the support plate, and a rack fixedly mounted on the mounting block corresponding to the position of the gear.

[0011] A further technical improvement of the present invention is as follows: a baffle is fixedly installed on the base on one side of the rotating seat, and a thrust spring is elastically arranged between the baffle and the rubber rod; when the extended end of the feeding cylinder extends to half its length, the gear is driven to rotate through the rack, the rubber rod rotates, and then the extended end of the feeding cylinder resets, so that the rubber rod drives the impact hammer to slightly impact the guide channel, the guide channel vibrates, and the cable tie waste accumulated inside is shaken off, so as to avoid the cable tie waste affecting the efficiency of subsequent cable tie locking; when the above method is difficult to shake off the accumulated cable tie waste, the extended end of the feeding cylinder extends to its longest state, at which time the gear will disengage from the rack, and the thrust spring stores force to push the rubber rod out, so that the impact hammer impacts the guide channel more violently, generating stronger vibration, which easily shakes off the cable tie waste. Then the extended end of the feeding cylinder resets, so that the pressure between the rubber rod and the guide channel increases, the rubber rod deforms, and when the gear and rack disengage again, the gear rotates to reset, and the deformation of the rubber rod is restored.

[0012] A further technical improvement of the present invention is that a cutting cylinder is hinged to the other side of the top of the support plate, a connecting rod is hinged to the extended end of the cutting cylinder, and one end of the connecting rod is fixedly connected to the rotating column.

[0013] A further technical improvement of the present invention is that: a control box is fixedly installed on the other side of the top of the base, a winding shaft for winding the cable tie is arranged laterally on the side of the control box, and a driving tool for driving the winding shaft is arranged inside the control box. The driving tool is prior art, and one end of the winding shaft movably passes through the guide groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In use, the extension of the cutting cylinder causes the connecting rod to rotate the rotating column, which in turn cuts the cable tie. The extension of the cutting cylinder then returns to its original position. The extension of the feeding cylinder moves the support plate, and due to inertia, the cable tie and the cut cable tie waste separate. This process tightens the cable tie by winding it around the shaft to prevent insufficient tightening. At the same time, the extension and retraction of the feeding cylinder causes the cable tie to shake, which separates the cable tie from the cable tie waste and prevents it from affecting subsequent cable tie tightening operations.

[0016] In use, when the extended end of the feeding cylinder extends to half its length, the rack drives the gear to rotate, causing the rubber rod to rotate. Then, the extended end of the feeding cylinder returns to its original position, causing the rubber rod to drive the impact hammer to slightly impact the guide channel. The guide channel vibrates, shaking off the cable tie waste accumulated inside, thus preventing the cable tie waste from affecting the efficiency of subsequent cable tie locking. When the above method is insufficient to shake off the accumulated cable tie waste, the extended end of the feeding cylinder extends to its maximum position. At this time, the gear disengages from the rack, and the thrust spring pushes the rubber rod out, causing the impact hammer to impact the guide channel more violently, generating stronger vibrations and easily shaking off the cable tie waste.

Detailed Implementation

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-5As shown, the automatic cable tie locking and cutting machine includes a base 5. A control box 6 is fixedly installed on one side of the top of the base 5. A winding shaft 10 for winding the cable tie is arranged laterally on the side of the control box 6. The control box 6 is equipped with a drive fixture for driving the winding shaft 10. The drive fixture is existing technology. A slider 7 is slidably arranged on the other side of the top of the base 5 via a guide rail. A support plate 3 is fixedly installed on the top of the slider 7. A feeding cylinder 8 for driving the slider 7 to move is also provided on the base 5. A winding mechanism 1 for tightening the cable tie is provided on the top of the support plate 3 near the control box 6. A vibration mechanism 4 for striking the winding mechanism 1 is provided in the middle of the base 5.

[0026] Please see Figures 1-4 As shown, the winding mechanism 1 includes a mounting base 103 fixedly connected to the support plate 3. A connecting block 101 is fixedly installed on the mounting base 103. A guide groove is provided inside the connecting block 101. A tape inlet 102 is provided at one end of the connecting block 101. The tape inlet 102 communicates with the guide groove. A rotating column 9 is also movably inserted on the connecting block 101. The rotating column 9 is arranged horizontally, and a cutting groove is provided at one end of the rotating column 9. The rotating column 9 is arranged perpendicularly to the tape inlet 102, and one end of the rotating column 9 moves through the guide groove around the winding shaft 10.

[0027] Please see Figure 3 and Figure 4 As shown, a guide channel 104 for recycling cable tie waste is provided on one side of the mounting base 103. The input end of the guide channel 104 is connected to the output end of the guide groove. The cable tie is manually inserted into the inlet 102. At this time, the extension end of the cutting cylinder 2 is in its shortest state. The cable tie enters the guide groove through the cutting groove and contacts the winding shaft 10. The cable tie is tightened by rotating the winding shaft 10. Then, the extension end of the cutting cylinder 2 extends, causing the connecting rod to drive the rotating column 9 to rotate, so that the cutting groove cuts the cable tie. The extension end of the cutting cylinder 2 then resets. The extension and retraction of the extension end of the feeding cylinder 8 drives the support plate 3 to move. Due to inertia, the cable tie and the cut cable tie waste are separated. This process tightens the cable tie by winding shaft 10 to avoid insufficient cable tie tightening. At the same time, the extension and retraction of the feeding cylinder 8 causes the cable tie to shake, causing the cable tie and the cable tie waste to separate, so as not to affect the subsequent cable tie tightening operation.

[0028] Please see Figure 2 and Figure 5 As shown, the vibration mechanism 4 includes a rotating seat fixedly connected to the base 5. A rubber rod 401 is rotatably mounted on the rotating seat via a pin. An impact hammer is fixedly mounted on the top of the rubber rod 401. The impact hammer contacts the guide channel 104. A gear 404 is fixedly mounted on one end of the pin. An mounting block 402 is fixedly mounted on the support plate 3. A rack 403 corresponding to the position of the gear 404 is fixedly mounted on the mounting block 402.

[0029] Please see Figure 5 As shown, a baffle 405 is also fixedly installed on the base 5 on one side of the rotating seat. A thrust spring 406 is elastically arranged between the baffle 405 and the rubber rod 401. When the extended end of the feeding cylinder 8 extends to half its length, the rack 403 drives the gear 404 to rotate, causing the rubber rod 401 to rotate. Then, the extended end of the feeding cylinder 8 is reset, causing the rubber rod 401 to drive the impact hammer to slightly impact the guide channel 104. The guide channel 104 vibrates, shaking down the cable tie waste accumulated inside, thus preventing the cable tie waste from affecting the efficiency of subsequent cable tie locking. When the above method is insufficient to remove the accumulated waste... When the cable tie waste is shaken off, the extended end of the feeding cylinder 8 extends to its longest state. At this time, the gear 404 will disengage from the rack 403. Meanwhile, the thrust spring 406 stores force to push out the rubber rod 401, causing the impact hammer to strike the guide channel 104 more violently, generating stronger vibrations and easily shaking off the cable tie waste. Then, the extended end of the feeding cylinder 8 resets, increasing the pressure between the rubber rod 401 and the guide channel 104, causing the rubber rod 401 to deform. When the gear 404 disengages from the rack 403 again, the gear 404 rotates to reset, and the deformation of the rubber rod 401 is restored.

[0030] Please see Figure 1 and Figure 2 As shown, a cutting cylinder 2 is hinged to the other side of the top of the support plate 3. A connecting rod is hinged to the extended end of the cutting cylinder 2, and one end of the connecting rod is fixedly connected to the rotating column 9.

[0031] Working Principle: In use, the cable tie is first manually inserted into the inlet 102. At this time, the extended end of the cutting cylinder 2 is at its shortest position. The cable tie passes through the cutting groove and enters the guide groove, contacting the winding shaft 10. The cable tie is tightened by rotating the winding shaft 10. Then, the extended end of the cutting cylinder 2 extends, causing the connecting rod to drive the rotating column 9 to rotate, causing the cutting groove to cut the cable tie. The extended end of the cutting cylinder 2 then returns to its original position. The extension and retraction of the extended end of the feeding cylinder 8 moves the support plate 3. Due to inertia, the cable tie and the cut cable tie waste separate. This process tightens the cable tie by winding the shaft 10, preventing insufficient cable tie tightening. At the same time, the extension and retraction of the feeding cylinder 8 causes the cable tie to shake, causing the cable tie to separate from the cable tie waste, preventing it from affecting the subsequent cable tie tightening operation. When the extended end of the feeding cylinder 8 extends to half its length, the rack 403 drives the gear 404 to rotate, and the rubber rod 4... When the 01 cylinder rotates, the extended end of the feeding cylinder 8 resets, causing the rubber rod 401 to drive the impact hammer to slightly impact the guide channel 104. The guide channel 104 vibrates, shaking off the cable tie waste accumulated inside, thus preventing the cable tie waste from affecting the efficiency of subsequent cable tie locking. When the above method is insufficient to shake off the accumulated cable tie waste, the extended end of the feeding cylinder 8 extends to its longest state. At this time, the gear 404 will disengage from the rack 403, and the thrust spring 406 stores force to push the rubber rod 401 out, causing the impact hammer to impact the guide channel 104 more violently, generating stronger vibrations, which easily shakes off the cable tie waste. The extended end of the feeding cylinder 8 then resets, increasing the pressure between the rubber rod 401 and the guide channel 104, causing the rubber rod 401 to deform. When the gear 404 disengages from the rack 403 again, the gear 404 rotates and resets, and the deformation of the rubber rod 401 is restored.
