Description

Technical Field

[0001] This utility model belongs to the field of hook binding machine technology, specifically relating to a knotless hook binding machine. Background Technology

[0002] In fishing, tying the leader line to the main line and hook and then winding it is a crucial operation that directly affects the fishing results and safety. Traditional hook-tying methods rely primarily on manual operation, requiring the operator to be skilled in complex winding techniques to tightly and securely wrap the leader line around the main line and hook. This manual method has several significant drawbacks.

[0003] From an efficiency perspective, manual hook-tying is tedious and time-consuming. Each hook-tying requires not only precisely threading the leader through the hook and connecting it to the main line, but also winding it according to a specific number of turns and sequence. For inexperienced workers, a single hook-tying session can take several minutes. Even skilled workers experience a significant decrease in speed after prolonged work, making it difficult to meet the needs of mass production of fishing tackle or the large-scale hook preparation by anglers. In fishing tackle manufacturing companies, the low efficiency of manual hook-tying severely restricts the expansion of production scale and order delivery cycles.

[0004] In terms of quality, manually tied hooks have poor consistency. The techniques, strength, and experience of different operators vary significantly, resulting in inconsistent results each time. Inconsistencies in the number of wraps and the tightness of the wrapping lead to unstable connection strength between the hook and the main line and leader. In actual fishing, if a large fish pulls on the line, a loosely tied section can easily come undone, allowing the fish to escape, affecting the fishing experience, and potentially causing safety issues due to a sudden line breakage.

[0005] Furthermore, manual hook tying demands a high level of skill from operators. Novices need extensive practice and long-term training to master basic hook-tying techniques, and companies must invest significant time and resources in training skilled hook-tying workers. With rising labor costs, fishing tackle manufacturers are experiencing substantial increases in production costs and reduced product price competitiveness, negatively impacting their market survival and development. Utility Model Content

[0006] To address the above problems, the purpose of this utility model is to provide a knotless hook tying machine that solves the problems of low efficiency, unstable quality, high skill requirements, and high cost associated with traditional manual hook tying.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a knotless line tying machine, comprising a base, a control box and a cross slide mounted on the base, a mounting seat mounted on the upper Y-axis slide of the cross slide, a line feeding mechanism and a wire nozzle mounted on the mounting seat, the line feeding mechanism including a support shaft, a spool of line fitted on the support shaft, the support shaft connected to the output shaft of a servo motor, the servo motor fixed on the mounting seat, one end of the servo motor connected to a circuit board, the servo motor and the chip module mounted on the circuit board electrically connected to the control box, a winding motor installed in the control box, the winding motor driving a connecting shaft, the connecting shaft being connected to a fishhook clamping mechanism via a coupling.

[0008] The beneficial effects of this utility model are as follows: Under the control of the control box, the cross slide automatically runs, driving the line feeding mechanism and the guide tip to move to one side of the fish hook held by the fish hook clamping mechanism. After manually attaching the end of the leader line to the fish hook shank, the winding motor is controlled to drive the fish hook to rotate around the hook shank to achieve efficient hook binding. The PLC, in conjunction with the chip module, monitors and provides feedback and adjusts the damping value of the servo motor shaft rotation in real time to ensure that the leader line is bound to the fish hook with appropriate tension and high quality.

[0009] In order to achieve stable control of the tension of the wire;

[0010] As a further improvement to the above technical solution: the chip module includes a main control chip, a driver chip, a communication chip, a power supply chip, and a position sensor chip.

[0011] The beneficial effects of this improvement are as follows: During the wire feeding process, as the support shaft drives the servo motor to rotate, the microcontroller communicates with the PLC through the communication chip to obtain the damping value signal and perform corresponding calculations, so that the motor is in a controllable damping state.

[0012] To ensure stable synchronous rotation between the bobbin and the support shaft;

[0013] As a further improvement to the above technical solution: a limiting plate is fixed on the support shaft, one end of the spool is abutted against the limiting plate, the end of the support shaft is provided with an internal threaded hole for a threaded connection clamping bolt, and a pressure plate is clamped between the clamping bolt and the other end of the spool.

[0014] The beneficial effects of this improvement are: by rotating the clamping bolt, the pressure plate and the limiting plate cooperate to clamp the bobbin, so that the bobbin and the support shaft can rotate stably and synchronously.

[0015] To ensure that the wound motor drives the fishhook clamping mechanism to rotate stably;

[0016] As a further improvement to the above technical solution: the fishhook clamping mechanism includes a clamping plate one and a clamping plate two. One end of the clamping plate one is connected to an end plate, and the end plate is connected to one end of a shaft. The shaft and the connecting shaft are adapted to be connected to the same coupling.

[0017] The beneficial effect of this improvement is that the wound motor can drive the fishhook clamping mechanism to rotate stably through the connecting shaft and coupling.

[0018] To securely hold the fishhook;

[0019] As a further improvement to the above technical solution: a T-shaped positioning boss is formed on the first clamping plate, and a groove for sliding connection of the T-shaped positioning boss is formed on the second clamping plate. Internal threaded through holes for threaded connection positioning bolts and clamping bolts are opened on the first clamping plate and the second clamping plate.

[0020] The beneficial effect of this improvement is that after the fishhook is placed between clamp plate one and clamp plate two, and the end of the fishhook abuts against the two side walls of the T-shaped positioning boss, the fishhook can be firmly clamped by tightening the clamping bolt.

[0021] To further improve the stability of the fishhook clamping mechanism in holding the fishhook;

[0022] As a further improvement to the above technical solution: an anti-slip groove is formed on one side of the clamping plate of the T-shaped positioning boss.

[0023] The beneficial effects of this improvement are: the anti-slip groove can increase the friction between the fishhook clamping mechanism and the fishhook, thereby improving the stability of the fishhook clamping.

[0024] To facilitate the installation of fishhooks;

[0025] As a further improvement to the above technical solution: the clamping plates one and two are provided with countersunk holes adapted to the filling springs.

[0026] The beneficial effects of this improvement are: the spring provides elastic support, and when the operator loosens the clamping bolt, the spring supports clamp plate one and clamp plate two, allowing the fishhook to be easily inserted into the gap between clamp plate one and clamp plate two.

[0027] To enable this device to conveniently and flexibly tie lines to fishhooks of different sizes;

[0028] As a further improvement to the above technical solution: a lead screw pair linear module parallel to the X-axis of the lower side of the cross slide is installed on the base on one side of the cross slide, and a proximity switch is installed on the slide of the lead screw pair linear module. The proximity switch is electrically connected to the PLC module in the control box.

[0029] The beneficial effect of this improvement is that by adjusting the position of the proximity switch, the movement distance of the cross slide in the X-axis direction is sensed and monitored, thereby controlling the binding distance of the hook by the device.

[0030] This device is used for convenient control purposes;

[0031] As a further improvement to the above technical solution: the control box includes an outer shell, in which a display screen, control switch, motor controller, power supply module and PLC module are installed.

[0032] The beneficial effect of this improvement is that operators can conveniently operate and use this device through the control box.

[0033] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0040] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0041] Example 1:

[0042] like Figure 1As shown in Figure 5: A knotless line binding hook machine includes a base 1, on which a control box 2 and a cross slide 3 are mounted. A mounting base 4 is mounted on the upper Y-axis slide of the cross slide 3. A line feeding mechanism 6 and a wire feed nozzle 8 are mounted on the mounting base 4. The line feeding mechanism 6 includes a support shaft 61, on which a wire spool 62 is fitted. The support shaft 61 is connected to the output shaft of a servo motor 66. The servo motor 66 is fixed to the mounting base 4, and one end of the servo motor 66 is connected to a circuit board 67. The chip module 68 installed on the motor 66 and circuit board 67 is electrically connected to the control box 2. The control box 2 is equipped with a winding motor 9, which drives a connecting shaft 10. The connecting shaft 10 is connected to the hook clamping mechanism 11 through a coupling. Under the control of the control box 2, the cross slide 3 automatically runs, driving the line feeding mechanism 6 and the wire nozzle 8 to move to one side of the hook held by the hook clamping mechanism 11. After manually attaching the end of the leader line to the hook shank, the winding motor 9 is controlled to drive the hook to rotate around the hook shank to achieve efficient hook binding.The PLC, in conjunction with the chip module 68, monitors and adjusts the damping value of the servo motor 66's shaft rotation in real time to ensure the line is securely and effectively tied to the hook with appropriate tension. The chip module 68 includes a main control chip, a drive chip, a communication chip, a power supply chip, and a position sensor chip. During line release, as the support shaft 61 drives the servo motor 66's shaft to rotate, the microcontroller communicates with the PLC via the communication chip to obtain the damping value signal and performs corresponding calculations, keeping the motor in a controllable damped state. A limiting plate 63 is fixed to the support shaft 61, and one end of the line spool 62 rests against the limiting plate 63. The end of the support shaft 61 has an internal threaded hole for a threaded clamping bolt 65. The clamping bolt 65 connects to the other end of the line spool 62. A pressure plate 64 is clamped between one end of the hook clamping mechanism 11. By rotating the clamping bolt 65, the pressure plate 64 cooperates with the limiting plate 63 to clamp the line spool 62, so that the line spool 62 and the support shaft 61 rotate stably and synchronously. The hook clamping mechanism 11 includes a first clamping plate 111 and a second clamping plate 114. One end of the first clamping plate 111 is connected to an end plate 112. The end plate 112 is connected to one end of a shaft 113. The shaft 113 and the connecting shaft 10 are adapted to be connected to the same coupling. The winding motor 9 can drive the hook clamping mechanism 11 to rotate stably through the connecting shaft 10 and the coupling. A T-shaped positioning boss 118 is formed on the first clamping plate 111, and a groove for sliding connection of the T-shaped positioning boss 118 is formed on the second clamping plate 114. The first clamping plate 111 and the second clamping plate 114... 4 has internal threaded through holes for threaded positioning bolts 115 and clamping bolts 116. The fishhook is placed between clamping plate 111 and clamping plate 214, with the end of the fishhook abutting against the two side walls of the T-shaped positioning boss 118. Tightening the clamping bolts 116 achieves a stable clamping of the fishhook. Clamping plate 111 on one side of the T-shaped positioning boss 118 has an anti-slip groove 119, which increases the friction between the fishhook clamping mechanism 11 and the fishhook, improving the stability of the fishhook clamping. Clamping plates 111 and 214 have countersunk holes for fitting springs 117. The springs 117 provide elastic support, supporting clamping plates 111 and 214 through elastic force when the clamping bolts 116 are loosened. 114, allowing the fishhook to be easily inserted into the gap between clamp 111 and clamp 114. A linear screw module 5, parallel to the X-axis of the lower side of the cross slide 3, is installed on the base 1 on one side of the cross slide 3. A proximity switch 7 is installed on the slide of the linear screw module 5. The proximity switch 7 is electrically connected to the PLC module in the control box 2. By adjusting the position of the proximity switch 7, the movement distance of the cross slide 3 in the X-axis direction is sensed and monitored, thereby controlling the binding distance of the fishhook. The control box 2 includes an outer casing 21, which houses a display screen 22, a control switch 23, a motor controller, a power supply module, and a PLC module. Operators can conveniently operate and use this device through the control box 2.

[0043] In this embodiment, the main control chip, driver chip, communication chip, power supply chip and position sensor chip in the chip module 68 are respectively: STM32F103RBT6, TB67H450, MAX485eimm, 78L05AMS1117 and MT6816.

[0044] The working principle of this technical solution is as follows: The fishhook to be tied is placed between clamping plate 111 and clamping plate 114 of the fishhook clamping mechanism 11. When placing the fishhook, the end of the fishhook abuts against the two side walls of the T-shaped positioning boss 118, providing a positioning function. After placing the fishhook, the clamping bolt 116 is tightened to achieve a stable clamping of the fishhook. According to the specifications of the fishhook and the requirements for tying the line, the position of the proximity switch 7 on the linear module 5 of the lead screw is adjusted. The proximity switch 7 is electrically connected to the PLC module in the control box 2. By adjusting the position of the proximity switch 7, the movement distance of the cross slide 3 in the X-axis direction can be sensed and monitored. According to the feedback signal from the proximity switch 7, the control box 2 controls the cross slide 3 to run automatically, driving the mounting base 4 installed on the Y-axis slide, as well as the line feeding mechanism 6 and the guide nozzle 8 on it, to move to one side of the fishhook held by the fishhook clamping mechanism 11. The main line is manually placed against one side of the fishhook shank, and the end of the leader line is wrapped around the outside of the fishhook shank and the main line 2-3 times and glued. After completing the preparation work, the winding motor 9 is started through the control box 2. The winding motor 9 drives the connecting shaft 10 to rotate. The connecting shaft 10 is connected to the shaft 113 of the fishhook clamping mechanism 11 through a coupling, thereby driving the clamping plate 111 and... The fishhook held by clamp 114 rotates around the hook shank and the main line. During the winding process, servo motor 66, under the control of control box 2, drives support shaft 61 to rotate. Support shaft 61 drives line spool 62 to rotate, realizing line release. The main control chip, drive chip, communication chip, power chip, and position sensor chip in chip module 68 work together. As the support shaft 61 drives the rotation axis of servo motor 66, the position sensor chip monitors the rotation in real time and transmits the signal to the main control chip. The main control chip communicates with the PLC module in control box 2 through the communication chip to obtain the damping value signal and perform corresponding calculations. The drive chip adjusts the operating state of the servo motor 66 according to the calculation results, so that the motor is in a controllable damping state, ensuring that the leader line is tied to the fish hook with appropriate tension and high quality. The guide nozzle 8 guides the leader line to wind around the fish hook according to the predetermined trajectory. As the fish hook rotates, the leader line gradually winds around the fish hook shank, completing the line binding operation. After the line binding is completed, the operation of the winding motor 9 and the servo motor 66 is stopped by the control box 2. The leader line tied to the fish hook shank is glued, and the clamping bolt 116 is loosened. Under the elastic force of the spring 117, the gap between the clamp plate 111 and the clamp plate 114 increases, and the fish hook with the line tied is taken out.
