Description

Technical Field

[0001] This utility model relates to the field of cable tie machine technology, and in particular to a cable tie machine with a guiding structure. Background Technology

[0002] Cable tie machines are devices specifically designed for automatic or semi-automatic cable tying. They use mechanical devices to quickly and accurately complete cable tying operations, significantly improving work efficiency and ensuring the consistency and strength of the cable ties.

[0003] Automatic cable tie machines currently come in two types: handheld and desktop. Desktop cable tie machines can automatically feed cable ties and use a ruler on the desktop to position the binding points of the objects being bundled. They have many applications. However, cable ties are made of plastic, and some may deform due to compression during transportation, causing the ends of the cable ties to become skewed. This means that the ends of the cable ties may not align with the end portion during the cable tie machine's operation, resulting in binding failure. The cable ties need to be manually removed, which affects work efficiency.

[0004] Therefore, how to enable cable tie machines to guide cable ties to a certain extent so that even cable ties with skewed ends can be used normally is a technical problem that the industry urgently needs to solve. Utility Model Content

[0005] The main purpose of this utility model is to provide a cable tie machine with a guiding structure, which aims to guide the cable ties to a certain extent, so that even cable ties with skewed ends can be used normally.

[0006] This utility model proposes a cable tie machine with a guiding structure, including a table. A cable tie guide groove is formed on one side of the upper surface of the table along its length. An end groove is formed on the rear part of the upper surface of the cable tie guide groove along its length. A through opening is formed vertically through the inner end of the end groove. A transparent pressure plate adapted to the contour of the cable tie guide groove is fixedly connected to the upper surface of the table above the cable tie guide groove. A guiding structure is provided at the rear part of the inner end of the cable tie guide groove, and a pressure strip structure is provided at the front part of the inner end of the cable tie guide groove.

[0007] Preferably, a ruler is fixedly connected to the upper surface of the tabletop and the rear part of the cable tie guide groove along the length of the tabletop. The upper surface of the ruler has a vertically extending through-hole that corresponds to the position of the through-hole. The guide structure includes a sliding block that is slidably connected to the inside of the through-hole along the width of the tabletop. A rear positioning block extending above the cable tie guide groove is fixedly connected to the top of the sliding block. The upper surface of the cable tie guide groove and both sides of the rear positioning block have vertically extending sliding grooves along the length of the tabletop. A slider is slidably connected to the inside of each of the two sliding grooves. An L-shaped side limiting piece is fixedly connected to the top of each of the two sliders. The two side limiting pieces are combined to form a U-shaped frame structure. A tension spring is fixedly connected to the inner end of each of the two sliders and the inner end surface of each of the two sliding grooves. A linkage structure is provided between the bottom ends of the sliding block and the two sliders.

[0008] Preferably, the linkage structure includes a triangular connecting seat fixedly connected to the bottom end of the sliding block and located below the table, and connecting blocks adapted to the inclined sides of the connecting seat are fixedly connected to the bottom ends of the two sliders. An electrically controlled telescopic rod is fixedly connected to the bottom end of the table and located behind the sliding block along the width direction of the table, and the movable rod of the electrically controlled telescopic rod is fixedly connected to the connecting seat.

[0009] Preferably, the pressure strip structure includes a device groove that is vertically opened through the front of the upper surface of the tabletop along the width direction and corresponds to the position of the through opening. A first connecting piece is fixedly connected to both sides of the lower surface of the tabletop and the middle of the device groove. A pressure claw is laterally rotatably connected between the two first connecting pieces. A first servo motor is laterally fixedly connected to the outer surface of one of the first connecting pieces. The output shaft of the first servo motor rotatably passes through the first connecting piece and is fixedly connected to one side surface of the pressure claw.

[0010] Preferably, a second connecting piece is fixedly connected to the lower surface of the tabletop and to the rear of both sides of the device groove. Two tensioning rollers are laterally rotatably connected between the two second connecting pieces. One end of the rotating shaft of each tensioning roller can rotatably pass through one of the second connecting pieces and extend outward. Gears are fixedly connected to the outer surface of the rotating shaft of each tensioning roller and to the outside of one of the second connecting pieces. The two gears mesh with each other. A second servo motor is laterally fixedly connected to the outer surface of the other second connecting piece. The output shaft of the second servo motor rotatably passes through the second connecting piece and is fixedly connected to one end of the rotating shaft of one of the tensioning rollers. A shearing device is provided on the lower surface of the tabletop and to the rear of the two tensioning rollers.

[0011] Preferably, both ends of the upper surface of the ruler are fixedly connected to a fixing block, and a sliding rod is fixedly connected laterally between two fixing blocks. Multiple positioning blocks are slidably connected to the outer surface of the sliding rod along its length.

[0012] Preferably, a vibratory feeder is provided on one side of the table, and the discharge end of the vibratory feeder extends to the outer end of the cable tie guide groove.

[0013] This invention, through the provision of a guiding structure, allows the device to guide the end of the cable tie. Even if the tie is slightly misaligned, it can be guided into the end hole. In actual use, when the end of the cable tie is flipped towards the end by the pressure strip structure, the sliding block is pushed forward by the electrically controlled telescopic rod, and the rear positioning block moves forward synchronously, guiding the end of the cable tie in the width direction of the table. At the same time, the side limiting pieces on both sides merge to form a U-shaped limiting frame structure, which guides the end of the cable tie in three other directions, thereby preventing problems such as binding failure caused by the misalignment of the cable tie end and preventing it from affecting work efficiency.

[0018] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] Reference Figure 1-3This invention proposes an embodiment of a cable tie machine with a guiding structure, comprising a table 1, a cable tie guide groove 3 formed on one side of the upper surface of the table 1 along its length, an end groove 4 formed on the rear part of the upper surface of the cable tie guide groove 3 along its length, a through opening 14 vertically extending through the inner end of the end groove 4, a transparent pressure plate 6 adapted to the contour of the cable tie guide groove 3 fixedly connected to the upper surface of the table 1 above the cable tie guide groove 3, a guiding structure provided at the rear part of the inner end of the cable tie guide groove 3, and a pressure strip structure provided at the front part of the inner end of the cable tie guide groove 3.

[0021] A vibratory feeder 2 is provided on one side of the table 1, and the discharge end of the vibratory feeder 2 extends to the outer end of the cable tie guide groove 3.

[0022] When the device is running, the cable ties are fed into the vibratory feeder 2, and the vibratory feeder 2 transports the cable ties so that the cable ties can be fed into the cable tie guide groove 3 in rows. The lower part of the cable tie guide groove 3 is equipped with a conveying wheel, which can drive the cable ties to move towards the inner end of the cable tie guide groove 3.

[0023] Vibratory feeder 2 is a mature existing technology, and its structure will not be described in detail here.

[0024] A ruler 7 is fixedly connected to the upper surface of the tabletop 1 and the rear part of the cable tie guide groove 3 along the length of the tabletop 1. A vertical cut 8 is opened on the upper surface of the ruler 7, which extends to the lower surface of the tabletop 1 and corresponds to the position of the through opening 14. The guiding structure includes a sliding block that is slidably connected to the inside of the cut 8 along the width direction of the tabletop 1. A rear positioning block 9 extending to the top of the sliding block is fixedly connected to the top of the sliding block. A sliding groove 11 is vertically opened on both sides of the rear positioning block 9 and is set along the length direction of the tabletop 1. A slider is slidably connected to the inside of the two sliding grooves 11. An L-shaped side limiting piece 12 is fixedly connected to the top of the two sliders. The two side limiting pieces 12 are combined to form a U-shaped frame structure. A tension spring is fixedly connected to the inner end of the two sliders and the inner end surface of the two sliding grooves 11 respectively. A linkage structure is provided between the bottom end of the sliding block and the two sliders.

[0025] The linkage structure includes a triangular connecting seat 10 fixedly connected to the bottom end of the sliding block and located below the table 1. The bottom ends of the two sliders are fixedly connected to connecting blocks 13 that are adapted to the inclined sides of the connecting seat 10. The bottom end of the table 1 and the rear part of the sliding block are fixedly connected to an electrically controlled telescopic rod 15 along the width direction of the table 1. The movable rod of the electrically controlled telescopic rod 15 is fixedly connected to the connecting seat 10.

[0026] When the innermost cable tie is pushed to the inner end position of the end groove 4, the hole at the end of the cable tie will be aligned with the through opening 14. The end of the cable tie can be pushed backward and pressed down by the pressure strip structure, so that the end of the cable tie passes through the hole at its end. During this process, the end of the cable tie can be guided by the guiding structure.

[0027] When the guiding structure is running, the movable rod of the electrically controlled telescopic rod 15 extends, driving the connecting seat 10 fixedly connected to it to move forward synchronously. This, in turn, drives the sliding block and the rear positioning block 9 at its top to move forward synchronously. The front end of the rear positioning block 9 is curved, and the end of the cable tie is limited and guided by it during the downward movement. At the same time, as the connecting seat 10 moves forward, the two connecting blocks 13, which are limited by its inclined surface, will move closer to each other under the action of the tension springs inside the two sliding grooves 11, causing the two side limiting pieces 12 to move closer to each other until they merge. After merging, they form a U-shaped frame structure. The inner edge of the frame structure is provided with a guide strip with an inner bevel. The frame structure and the rear positioning block 9 cooperate to form a rectangular guide frame around the end of the cable tie. This structure can prevent the end of the cable tie from being unable to be inserted into the end hole due to its own tilt or other reasons during the pressing process. After the cable tie is pressed in, the piston rod of the electric telescopic rod 15 retracts, driving the rear positioning block 9 to reset. At the same time, the sliding block and the connecting seat 10 reset. Under the action of the connecting seat 10, the two connecting blocks 13 are pushed outward, and the two side limit pieces 12 will separate, thus not affecting the removal of the cable tie.

[0028] The pressure strip structure includes a device groove 5 that is vertically opened through the front of the upper surface of the tabletop 1 along the width direction and corresponds to the position of the through opening 14. The lower surface of the tabletop 1 and the two sides located in the middle of the device groove 5 are fixedly connected to the first connecting piece 17. The two first connecting pieces 17 are laterally rotatably connected to the pressure claw 18. The outer surface of one of the first connecting pieces 17 is laterally fixedly connected to the first servo motor 19. The output shaft of the first servo motor 19 rotatably passes through the first connecting piece 17 and is fixedly connected to one side surface of the pressure claw 18.

[0029] The rotation of the output shaft of the first servo motor 19 can drive the pressure claw 18 to rotate, which can flip the end of the cable tie backward and press it down, pressing the end of the cable tie into the inside of the cable tie port.

[0030] A second connecting piece 20 is fixedly connected to the lower surface of the tabletop 1 and to the rear of both sides of the device groove 5. Two tensioning rollers 21 are laterally rotatably connected between the two second connecting pieces 20. One end of the rotating shaft of each tensioning roller 21 can rotatably pass through one of the second connecting pieces 20 and extend outward. Gears 23 are fixedly connected to the outer surface of the rotating shaft of each of the two tensioning rollers 21 and to the outside of one of the second connecting pieces 20. The two gears 23 mesh with each other. A second servo motor 22 is laterally fixedly connected to the outer surface of the other second connecting piece 20. The output shaft of the second servo motor 22 rotatably passes through the second connecting piece 20 and is fixedly connected to one end of the rotating shaft of one of the tensioning rollers 21. A shearing device 24 is provided on the lower surface of the tabletop 1 and to the rear of the two tensioning rollers 21.

[0031] After the end of the cable tie is pressed into the port, it will move downward a certain distance. When it moves between the two tensioning rollers 21, it will be pulled down by the tensioning rollers 21. This structure can tighten the cable tie. After tightening, the cutting device 24 will be activated and the blade on it will cut off the excess part of the cable tie.

[0032] The second servo motor 22 runs continuously, and its output shaft rotates to drive a tensioning roller 21 to rotate. The gears 23 on the outside of the two tensioning rollers 21 mesh with each other, which causes the two tensioning rollers 21 to rotate synchronously in opposite directions, thereby tightening the cable ties. The outer surfaces of the two tensioning rollers 21 are provided with anti-slip textures to ensure their tightening effect and avoid slippage.

[0033] The shearing device 24 is a mature existing technology, and its structure will not be described in detail here. The electrically controlled telescopic rod 15, the first servo motor 19 and the second servo motor 22 in the device are all controlled by the central control, which enables multiple structures to cooperate with each other. After the tensioning roller 21 tightens the end of the cable tie, the excess part of the cable tie is cut off in a short time, avoiding jamming of the structure in the equipment.

[0034] The connector 10 has an inclined guide groove 16 at the front center. When the end of the cable tie passes through its port and moves down, it will be guided by the guide groove 16 to the space between the two tensioning rollers 21.

[0035] Both ends of the upper surface of the ruler plate 7 are fixedly connected to the fixing blocks 25, and the two fixing blocks 25 are horizontally fixedly connected to the slide rod 26. Multiple positioning blocks 27 are slidably connected to the outer surface of the slide rod 26 along its length.

[0036] The upper surface of the positioning block 27 has a screw hole, and a screw is connected to it by a thread. The height of the screw can be changed by rotating the screw. The positioning block 27 can be fixed in position by friction when the bottom end of the screw contacts the surface of the slide rod 26. The positioning block 27 can adjust its position according to the scale on the ruler 7. It can be used to position the material being bundled during the bundling process.

[0037] During operation, the device feeds cable ties into the vibratory feeder 2, which then transports the ties in rows into the cable tie guide groove 3. A conveyor wheel is located at the bottom of the guide groove 3, driving the ties towards its inner end. When the innermost ties are pushed to the inner end of the end groove 4, the hole at the end of the ties aligns with the through opening 14. A pressure strip structure pushes and presses the end of the ties backward, allowing it to pass through the hole. During this process, the guide structure guides the end of the ties. When the guide structure operates, the movable rod of the electrically controlled telescopic rod 15 extends, causing the connecting seat 10, which is fixedly connected to it, to move forward synchronously. This, in turn, causes the sliding block and its top rear positioning block 9 to move forward synchronously. The front end of the rear positioning block 9 is curved. As the end of the ties is pressed down... The two connecting blocks 13, which are limited by the inclined surface of the connecting seat 10, will move closer to each other under the action of the tension spring inside the two sliding grooves 11, so that the two side limiting pieces 12 will move closer to each other until they merge. After merging, they form a U-shaped frame structure. The inner edge of the frame structure is provided with a guide strip with an inclined inner side. The frame structure and the rear positioning block 9 can form a rectangular guide frame around the end of the cable tie. This structure can prevent the end of the cable tie from being unable to be inserted into the hole at the end due to its own tilt or other reasons during the pressing process. After the cable tie is pressed in, the piston rod of the electric telescopic rod 15 retracts, driving the rear positioning block 9 to reset. At the same time, the sliding block and the connecting seat 10 reset. Under the action of the connecting seat 10, the two connecting blocks 13 are pushed outward, and the two side limiting pieces 12 will separate, which will not affect the removal of the cable tie.

[0038] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
