Description

Technical Field

[0001] This utility model relates to the field of cable tie binding machine technology, specifically to an improved irregular-shaped cable tie binding machine. Background Technology

[0002] Cable ties (also known as straps or nylon straps) are a widely used tool for securing or binding items. They are typically made of injection-molded plastic and have a certain degree of strength and durability.

[0003] To meet diverse usage needs, various cable tie binding machines have emerged on the market. For example, the handheld irregular-shaped cable tie binding machine disclosed in authorization announcement number CN219295755U specifically discloses a housing, and a tightening mechanism, a cutting mechanism, a speed reduction transmission mechanism, and an electronic drive device sequentially arranged on a bracket within the housing. The tightening mechanism includes a drive wheel and a driven wheel that cooperate with the drive wheel, which are connected to the electronic drive device via the cutting mechanism and the speed reduction transmission mechanism. Feed channels and discharge channels communicating with the outside are respectively provided at the front and rear of the tightening mechanism. The cutting mechanism includes a cutter, a cutting wheel, and a spring reset assembly for resetting the cutter and the cutting wheel. The middle part of the cutter is hinged to the bracket, with the front end being a blade facing the position between the feed channel and the tightening mechanism. The upper side of the rear end is connected to the spring reset assembly, and the lower side of the rear end is connected to the cutting wheel. The cutting wheel is movably mounted on the bracket, and its two sides are respectively connected to the drive wheel and the speed reduction transmission mechanism. The electronic drive device is a motor.

[0004] Meanwhile, some desktop cable tie binding machines are positioned on a workbench, and during use, the machine remains stationary while the workpiece moves. Multiple desktop cable tie binding machines can also be arranged horizontally in sequence with intervals between them, allowing multiple machines to bind workpieces at multiple locations. However, if the structure of the aforementioned handheld shaped cable tie binding machine is applied to a desktop cable tie binding machine, there is still room for improvement. For example: (1) Because the motor of the handheld shaped cable tie binding machine is horizontally positioned, and the motor itself has a certain length, the gap between two adjacent desktop cable tie binding machines cannot be made small, resulting in an excessively large distance between the two binding positions formed by the two adjacent machines binding the workpiece. However, some workpieces require that the two adjacent binding positions not be too large. Therefore, this design cannot meet the needs of such workpieces. (2) Since the blade is set on the cutter, and the cutter needs to be connected to the bracket, the return spring assembly and the cutting wheel, etc., it is very troublesome to disassemble and replace the cutter when the blade is damaged. Because the connection structure of the cutter is relatively complex, it is easy to affect the position of other parts during disassembly and assembly.

[0005] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide an improved irregular cable tie binding machine. By setting the main body of the motor to face forward, the distance between two adjacent cable tie binding machines can be shortened. Moreover, the cutter is divided into a swing block and a blade body, so that the blade body can be disassembled and replaced separately after the blade is damaged, without having to remove or replace the entire swing block at the same time.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: An improved shaped cable tie binding machine includes a housing, a start switch, a stop switch, a bracket mounted on the housing, and a tensioning device, a cutting device, and a motor respectively mounted on the bracket. A feeding channel is provided on the upper surface of the housing. The tensioning device includes a driving wheel and a driven wheel that cooperate with each other and are located below the feeding channel. The cutting device includes a cutter, a cutting wheel, and a spring return assembly for resetting the cutter and the cutting wheel. The cutter includes a swing block and a blade body. The middle part of the swing block is hinged to the bracket, allowing the swing block to swing left and right. The blade body is detachably and movably connected to the upper end of the swing block, with one end of the blade body being a cutting edge. The cutting edge is located between the top of the housing and the tensioning device. A protrusion on a first side of the lower end of the swing block connects to the spring return assembly, and a second side connects to the cutting wheel. The cutting wheel is mounted on the bracket and can move left and right. The main body of the motor extends forward, and the motor can drive the driving wheel and the cutting wheel to rotate.

[0008] Furthermore, it also includes a start switch and a stop switch; the stop switch is mounted on the bracket and cooperates with the protrusion; the start switch can be used to control the motor to start, and the stop switch can be used to control the motor to stop.

[0009] Furthermore, the protrusion includes a fixed portion and a magnet disposed on the fixed portion; the stop switch is a Hall sensor; when the protrusion swings in the direction of the stop switch, the magnet can be sensed by the stop switch.

[0010] Furthermore, the start switch is a sensor or a contact switch; when the start switch is a sensor, the start switch is respectively installed in the first mounting hole and the second mounting hole of the housing and the bracket, and the sensing end of the start switch is facing the feed channel or facing the outside of the housing.

[0011] Furthermore, the blade is in the shape of a downwardly concave arc or a C-angle.

[0012] Furthermore, a limiting block is provided on the inner wall at the upper end of the outer shell; a through hole is provided on the limiting block that runs horizontally and cooperates with the blade body; a guide hole is provided on the limiting block that runs vertically and communicates with the feed channel and the through hole respectively; the end of the blade body with the cutting edge is fitted into the through hole.

[0013] Furthermore, a protrusion with an arc-shaped surface is provided at the upper end of the swing block; a sleeve hole that mates with the protrusion is provided in the middle of the blade body; the swing block can be sleeved on the protrusion through the sleeve hole to form a movable connection between the swing block and the blade body.

[0014] Furthermore, the cutting wheel includes a cutting gear and a cutting stop wheel connected by a rotating shaft, the rotating shaft being movable left and right and passing through a groove in the bracket; one side of the cutting gear is driven to the output shaft of the motor, and the other side of the cutting gear is driven to the drive wheel; the second side of the lower end of the swing block abuts against the surface of the cutting stop wheel.

[0015] Furthermore, it also includes a first bevel gear, a second bevel gear, and at least two transmission gears; the first bevel gear is mounted on the output shaft of the motor; the second bevel gear meshes with the first bevel gear; the second bevel gear and the cutting gear can be connected by transmission gears; the cutting gear and the drive wheel can also be connected by transmission gears.

[0016] The beneficial effects of this utility model are as follows: (i) By setting the main body of the motor to face forward, this utility model allows multiple improved irregular cable tie binding machines to be arranged horizontally in sequence. Compared with the prior art, the distance between two adjacent cable tie binding machines can be shortened, so that the binding positions formed by each cable tie binding machine for binding the workpiece will not be too far apart, so as to meet the needs of different users.

[0017] (ii) By dividing the cutter into a swing block and a blade body, the present invention allows for easy disassembly and replacement of the blade body separately, so that when the blade wears out, the blade body can be replaced separately without removing or replacing the entire swing block at the same time, thus avoiding the impact on other parts when disassembling or assembling the swing block.

[0018] (III) By setting a start switch and a stop switch, this utility model can be conveniently used to control the start and stop of the motor. For example, when the start switch senses a start signal, the motor starts, and when the stop switch senses a stop signal, the motor stops. This allows the motor to accurately control the tensioning device and the cutting device to perform corresponding actions, thereby accurately cutting off the excess part of the cable tie tail to complete the binding.

[0022] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0023] like Figures 1-9 As shown, an improved irregular cable tie binding machine includes a housing 1, a bracket 2 mounted on the housing 1, and a tensioning device 5, a cutting device 6, and a motor 7 respectively mounted on the bracket 2.

[0024] The outer casing 1 has a feeding channel 11 on its upper surface, and the tensioning device 5 includes a drive wheel 51 and a driven wheel 52 that cooperate with each other and are located below the feeding channel 11.

[0025] like Figures 4-7 As shown, the cutting device 6 includes a cutter 61, a cutting wheel 62, and a spring return assembly 63 for resetting the cutter 61 and the cutting wheel 62. The cutter 61 includes a swing block 611 and a blade body 612. The middle part of the swing block 611 is hinged to the bracket 2 so that the swing block 611 can swing left and right. The blade body 612 is detachably connected to the upper end of the swing block 611, and one end of the blade body 612 is a cutting edge. The cutting edge is located between the top of the housing 1 and the tensioning device 5. The protrusion 613 on the first side of the lower end of the swing block 611 is connected to the spring return assembly 63, and the second side is connected to the cutting wheel 62. The cutting wheel 62 is mounted on the bracket 2 and can move left and right. With the above configuration, the cutter 61 can be set as a split structure, which is conducive to the separate disassembly and replacement of the blade body 612 without replacing the swing block 611 at the same time, thus greatly facilitating the convenience of replacement.

[0026] In this embodiment, the main body of the motor 7 extends forward, and the motor 7 can be used to drive the drive wheel 51 and the cut-off wheel 62 to rotate.

[0027] In summary, by aligning the main body of the motor 7 forward, this invention allows multiple improved irregular-shaped cable tie binding machines to be arranged horizontally in sequence. This shortens the distance between adjacent cable tie binding machines, preventing excessive distances between the binding positions formed by each machine, thus meeting the needs of different users. By dividing the cutter 61 into a swing block 611 and a blade body 612 (i.e., the swing block 611 does not have a blade), the blade body 612 can be easily disassembled and replaced separately. This allows for individual replacement of the blade body 612 when the blade wears out, without needing to remove or replace the entire swing block 611 simultaneously, thus avoiding interference with other components during disassembly or assembly.

[0028] like Figure 3 and Figure 8As shown, this embodiment also includes a start switch 3 and a stop switch 4. The stop switch 4 is mounted on the bracket 2 and cooperates with the protrusion 613; the start switch 3 can be used to control the motor 7 to start, and the stop switch 4 can be used to control the motor 7 to stop.

[0029] like Figure 8 As shown, the protrusion 613 includes a fixed part (not shown in the figure) and a magnet 614 disposed on the fixed part; the stop switch 4 is a Hall sensor; when the protrusion 613 swings towards the stop switch 4, the magnet 614 is sensed by the stop switch 4, and then the motor 7 stops. Alternatively, it can be configured such that after the magnet 614 is sensed by the stop switch 4, the motor 7 stops after a delay of several seconds, and this delay time can be set according to actual needs, for example, a delay of 0.5 seconds. Therefore, in this design, since the motor 7 continues to run for 0.5 seconds after receiving the stop signal, the drive wheel 51 will also continue to rotate for 0.5 seconds accordingly, so that the tail of the cable tie, after being cut off, will continue to be pulled and moved a certain distance by the drive wheel 51 and the driven wheel 52, thereby causing the cut part of the cable tie to leave the tensioning device 5, thus preventing the cut part of the cable tie from being left between the drive wheel 51 and the driven wheel 52.

[0030] Specifically, the start switch 3 is a sensor or a contact switch.

[0031] When the start switch 3 is a sensing sensor, the start switch 3 is respectively installed in the first mounting hole 12 and the second mounting hole 21 of the housing 1 and the bracket 2, and the sensing end of the start switch 3 is directly opposite the feed channel 11 or directly opposite the outside of the housing 1. Figures 1-4 As shown, in this embodiment, the sensing end of the start switch 3 is directly facing the feed channel 11. Therefore, after the end of the cable tie is inserted into the feed channel 11, it can be sensed by the start switch 3, which transmits a start signal to the motor 7, and then the motor 7 starts. Alternatively, if the sensing end of the start switch 3 is directly facing the outside of the housing 1, a worker's hand can be brought near its sensing end. In this case, the start switch 3 senses the hand and sends a start signal, then the motor 7 starts.

[0032] In other embodiments, the start switch 3 can also be directly disposed outside the housing 1, allowing the operator to output a start signal to the start switch 3 from outside the housing 1. For example, after placing the start switch 3 on a workbench outside the housing 1, the operator can operate it directly. If the start switch 3 is a fiber optic sensor or an infrared sensor, the operator simply brings their hand close to the sensing end of the start switch 3 to send a start signal. If the start switch 3 is a contact switch, the operator can directly touch the start switch 3 to send a start signal.

[0033] By setting the start switch 3 and stop switch 4 as described above, the motor 7 can be conveniently controlled to start and stop. For example, when the start switch 3 senses a start signal, the motor 7 starts, and when the stop switch 4 senses a stop signal, the motor 7 stops. This allows the motor 7 to precisely control the tensioning device 5 and the cutting device 6 to perform corresponding actions, thereby accurately cutting off the excess part of the cable tie tail to complete the bundling.

[0034] like Figures 6-7 As shown, the blade is concave in an arc shape or C-angle, so that when the end of the cable tie is cut off by the blade, the end of the cable tie will be convex in an arc shape or C-angle. This shape matches the shape of the blade, making it less likely to "cut your hand" at the end of the cable tie, making it safer to use.

[0035] like Figures 1-7 As shown, a limiting block 64 is also provided on the inner wall of the upper end of the outer casing 1; a through hole 641 is provided on the limiting block 64, which runs horizontally and mates with the blade body 612; a guide hole 642 is also provided on the limiting block 64, which runs vertically and communicates with the feed channel 11 and the through hole 641 respectively; the end of the blade body 612 with the cutting edge is fitted into the through hole 641. Therefore, by setting the limiting block 64, the blade body 612 can be limited to prevent it from deviating from the preset movement path.

[0036] like Figures 1-7 As shown, a protrusion 615 with an arc-shaped surface is provided at the upper end of the swing block 611; a sleeve hole 616 that mates with the protrusion 615 is provided in the middle of the blade body 612; the swing block 611 can be sleeved on the protrusion 615 through the sleeve hole 616 to form a movable connection between the swing block 611 and the blade body 612, and greatly facilitates the assembly and disassembly of the blade body 612. When you want to remove the blade body 612, you only need to move the blade body 612 out of the limiting block 64, and then remove the blade body 612 from the protrusion 615.

[0037] like Figure 4 and Figure 9 As shown, the cutting wheel 62 includes a cutting gear 622 and a cutting stop wheel 623 connected by a rotating shaft 621. The rotating shaft 621 is movably inserted into a groove (not shown) in the bracket 2. One side of the cutting gear 622 is connected to the output shaft of the motor 7, and the other side of the cutting gear 622 is connected to the drive wheel 51. The second side of the lower end of the swing block 611 abuts against the surface of the cutting stop wheel 623. This arrangement allows the cutting wheel 62 to synchronously drive the cutting stop wheel 623 and the drive wheel 51 to perform corresponding actions when driven by the motor 7 using the cutting gear 621.

[0038] like Figure 9 As shown, in this embodiment, it also includes a first bevel gear 65, a second bevel gear 66, and at least two transmission gears 67; the first bevel gear 65 is mounted on the output shaft of the motor 7; the second bevel gear 66 meshes with the first bevel gear 65; the second bevel gear 66 and the cut-off gear 622 can be connected via the transmission gears 67; the cut-off gear 622 and the drive wheel 51 can also be connected via the transmission gears 67. Therefore, with the above arrangement, the output power of the motor 7 can be transmitted to the transmission gears 67 via the first bevel gear 65 and the second bevel gear 66, and then to the cut-off gear 622, while the cut-off gear 622 can also transmit power to the drive wheel 51 via the transmission gears 67.

[0039] like Figure 4 As shown, the spring return assembly 63 includes an adjusting rod 631 and a spring 632. The adjusting rod 631 is movably mounted on the bracket 2, and its upper end is movably connected to the protrusion 613. The spring 632 is sleeved on the adjusting rod 631, with its upper end positioned (specifically, it may abut against the bracket 21), and its lower end connected to the lower end of the adjusting rod 631. This configuration allows the adjusting rod 631 to be reset using the spring 632.

[0040] like Figure 8As shown, in this embodiment, an adjustable slider 633 is sleeved on the lower end of the adjusting rod 631; the first side of the adjusting slider 633 is inserted into the adjusting groove 23 of an adjusting block 22 of the bracket 2; a scale value 24 is provided on the top surface of the adjusting block 22; a pointer 634 for pointing to the scale value 24 is also provided on the first side of the adjusting slider 633; ​​a vertically extending strip hole 13 and an observation window 14 facing the scale value 24 and the pointer 634 are provided on the outer casing 1; a threaded hole 635 is provided on the second side of the adjusting slider 633; ​​a bolt (not shown in the figure) is correspondingly provided in the strip hole 13, and the shank of the bolt is threaded into the threaded hole 635. The above arrangement allows for accurate adjustment of the position of the adjusting slider 633, and after adjusting the position of the adjusting slider 633, the extension and retraction force of the adjusting spring 632 can be adjusted accordingly. During adjustment, loosening the bolt allows the adjusting slider 633 to move. The operator can observe the pointer 634 through the observation window 14, which will correspondingly point to different positions on the scale 24, thus accurately adjusting the position of the adjusting slider 633. After adjusting the slider 633, the bolt is tightened. More specifically, adjusting the adjusting slider 633 upwards compresses the spring 632. This requires the cutting wheel 62 to exert greater force to push the swing block 611 and compress the spring 632 again, allowing the driving wheel 51 and the driven wheel 52 to pull the cable tie's tail tighter, thus strengthening the tension of the cable tie by the tensioning device 5. Similarly, adjusting the adjusting slider 633 downwards correspondingly loosens the tension of the cable tie by the tensioning device 5.

[0041] like Figure 1 As shown, in this embodiment, a slot 15 for securing the head of the cable tie is provided on the upper surface of the outer casing 1; the feeding channel 11 is located on one side of the slot 15. The slot 15 can be used to position the head of the cable tie, while the feeding channel 11 can be used to insert the cable tie into the workpiece after it has been bundled, so as to perform the subsequent cutting action.

[0042] The following describes the specific working principle of this utility model in order to help you understand it: First, such as Figure 10 As shown, at least two improved shaped cable tie binding machines of this invention are sequentially and alternately installed on a workbench (not shown in the figure). In this arrangement, the motors 7 in each improved shaped cable tie binding machine are all positioned facing forward. This design saves installation space and prevents the distance between the two machines from becoming too close. During the binding process, the worker needs to sequentially bind the workpiece at various positions on each improved shaped cable tie binding machine.

[0043] The following description uses the operation of one of these improved irregular-shaped cable tie binding machines as an example; other improved irregular-shaped cable tie binding machines can be operated using the same method: First, manually insert the head of the cable tie into the slot 15; next, manually wrap the tail of the cable tie around the workpiece once and then insert it into the feed channel 11; next, when the tail of the cable tie enters the feed channel 11 and is inserted between the drive wheel 51 and the driven wheel 52, it is sensed by the start switch 3, and then the motor 7 starts; next, the drive wheel 51 and the driven wheel 52 tighten the tail of the cable tie. When the tightening device 5 pulls the cable tie to its limit, that is, when the workpiece is completely tied, the drive wheel 51 and the driven wheel 52 of the tightening device 5 can no longer rotate (because the resistance of the drive wheel 51 and the driven wheel 52 is too great). At this time, the motor 7 will continue to apply external force to the cutting gear 622 through the first bevel gear 65, the second bevel gear 66 and the transmission gear 67. Therefore, it will drive the cutting gear 622 to continue rotating a certain distance through the transmission gear 67, and due to the resistance on the upper side, the cutting gear 622 will gradually move a certain distance towards the swing block 611, simultaneously driving the cutting stop wheel 623 to move and the rotating shaft 622 to move in the slide groove; next, after the cutting stop wheel 623 moves, it will push the lower end of the swing block 611 to swing to one side and drive the adjusting rod 631 to compress the spring 632; next, the upper end of the swing block 611 will drive the blade 612 to swing to the other side, so that the excess part of the cable tie can be cut off by the blade; next, when the lower end of the swing block 611 swings until the magnet 614 is stopped. After the switch 4 is activated, the motor 7 stops after a 0.5-second delay, allowing the drive wheel 51 and the driven wheel 52 to send the cut cable tie out of the tensioning device 5. Next, the spring 632 begins to extend and drives the adjusting rod 631 and the swing block 611 to reset. During the reset process, the swing block 611 also drives the blade 612 to reset, and the swing block 611 presses against the cutting stop wheel 623, thereby causing the cutting stop wheel 623 to drive the cutting gear 622 and the rotating shaft 621 to reset. When the cutting wheel 62 has reset, the cutting of one cable tie is completed. The cutting of other cable ties can then be performed. The specific steps are simply to repeat the above steps.

[0044] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
