Description

Technical Field

[0001] This utility model relates to the field of fishing net processing technology, and in particular to a threading device for fishing net processing. Background Technology

[0002] Fishing nets generally refer to nets used for fishing. Fishing nets are usually made of fishing line. Currently, the weaving and processing of fishing nets are basically completed by weaving machines. When weaving fishing nets, weaving machines need to use a threading device to fix the fishing line.

[0003] Chinese Patent No. CN221522977U discloses a highly reliable net-threading device for processing fishing nets. This device guides the net line by setting a first guide wheel and a second guide wheel. During threading, the second guide wheel is first lowered to its lowest point. Then, the net line is threaded through the first and second guide wheels using a threading mechanism. Afterward, the threading mechanism is removed, and the height of the second guide wheel is readjusted to ensure that the net line can be processed in a stable state. During the processing, the height of the second guide wheel can also be adjusted to adjust the tension of the net line.

[0004] However, the device still has shortcomings: the tension adjustment of the network cable requires manual operation by the staff. During the operation of the device, the network cable is transmitted at a very fast speed, which makes the tension adjustment operation very difficult, time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a threading device for fishing net processing.

[0006] The technical solution of this utility model is: a threading device for processing fishing nets, including a base plate, a protective cover on the base plate, and guide wheels A and B spaced apart on the inner wall of the protective cover; The lower end of the carriage is inserted into the protective cover and slidably connected to the top plate of the protective cover. The lower end of the carriage is equipped with a guide wheel C, which is located between guide wheel A and guide wheel B. An air shaft is rotatably mounted on a protective cover and located at the end of guide wheel A away from guide wheel B. A clamping assembly is mounted on and slidably connected to the protective cover. A drive component is mounted on the protective cover and drives the clamping component to slide, so as to feed the wire end from the input end to the output end of the protective cover; Brake pads are slidably mounted on a protective cover, and an electromagnet is mounted on the protective cover to adjust the braking resistance between the brake pads and the outer wall of the air shaft. And an adjustment mechanism, which is set on the protective cover, adjusts the current of the electromagnet according to the descent height of the guide wheel C when it is in operation.

[0007] Preferably, the carriage is provided with a slot, and a locking block that matches the slot is slidably provided on the top plate of the protective cover, so that the guide wheel C is locked in the high position of the protective cover by the cooperation of the locking block and the slot.

[0008] Preferably, an iron plate is provided at the top of the carriage, and a counterweight is magnetically attached to the iron plate.

[0009] Preferably, the clamping assembly includes a slider A, a crossbar, a clamping plate, a pull rod, and a spring A. A limiting groove is provided on the inner wall of the protective cover. The slider A is located in the limiting groove and slides along its length. The crossbar is connected to the slider A and has a sliding groove. The clamping plate is located in the sliding groove and slides along its length. One end of the pull rod is inserted into the sliding groove and connected to the clamping plate. A pull ring is provided at the end of the pull rod that extends out of the sliding groove. The spring A is sleeved on the pull rod, and both ends of the spring A abut against the clamping plate and the end of the sliding groove near the pull ring, respectively.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: By incorporating a guide wheel C that can slide up and down, an air shaft for fixing the fishing line spool, and clamping and driving components for gripping and conveying the fishing line, the clamping components can easily pass the fishing line over guide wheels A and B when guide wheel C is pulled up to its highest position, with the fishing line positioned below guide wheel C.

[0015] Example 1

[0016] like Figures 1-3As shown, this utility model proposes a net-threading device for fishing net processing, comprising a base plate 1, a slide 5, an air shaft 9, a clamping assembly, a drive assembly, a brake pad 18, and an adjustment mechanism. A protective cover 2 is mounted on the base plate 1, and guide wheels A3 and B4 are spaced apart on the inner wall of the protective cover 2. The lower end of the slide 5 is inserted into the protective cover 2 and slidably connected to the top plate of the protective cover 2. A guide wheel C6 is mounted on the lower end of the slide 5, located between guide wheels A3 and B4. A slot 51 is provided on the slide 5, and a locking block 8 adapted to the slot 51 is slidably mounted on the top plate of the protective cover 2 to lock the guide wheel C6 at a high position in the protective cover 2 through the cooperation of the locking block 8 and the slot 51. An iron plate is mounted at the top of the slide 5, and a counterweight 7 is magnetically attached to the iron plate. The air shaft 9 is rotatably mounted on the protective cover 2 and located at the end of guide wheel A3 away from guide wheel B4. The clamping assembly is mounted on the protective cover 2 and slidably connected to it. The clamping assembly includes a slider A10, a crossbar 12, a clamping plate 13, a pull rod 14, and a spring A15. Slider A10 and crossbar 12 are both located above guide wheels A3 and B4, and when guide wheel C6 is in a high position, slider A10 and crossbar 12 are both located below guide wheel C6. A limiting groove is provided on the inner wall of the protective cover 2. Slider A10 is located in the limiting groove and slides along its length. Crossbar 12 is connected to slider A10 and has a sliding groove 121. Clamping plate 13 is located in the sliding groove 121 and slides along its length. One end of pull rod 14 is inserted into the sliding groove 121 and connected to clamping plate 13. A pull ring is provided at the end of pull rod 14 extending out of the sliding groove 121. Spring A15 is sleeved on pull rod 14, and both ends of spring A15 abut against clamping plate 13 and the end of sliding groove 121 near the pull ring, respectively. The drive assembly is mounted on the protective cover 2. The drive assembly includes a lead screw 11, which is rotatably connected to the protective cover 2. The lead screw 11 passes through and is threadedly connected to the slider A10. A crank is provided at the end of the lead screw 11 extending out of the protective cover 2. In operation, the drive assembly drives the clamping assembly to slide, thereby feeding the wire end from the input end to the output end of the protective cover 2. A brake pad 18 is slidably mounted on the protective cover 2. An electromagnet 17 is provided on the protective cover 2 to adjust the braking resistance between the brake pad 18 and the outer wall of the air shaft 9. A slider B16 is slidably connected to the inner wall of the protective cover 2. The end of the brake pad 18 furthest from the air shaft 9 is connected to the slider B16. An electromagnet 17 is mounted on the inner wall of the protective cover 2, located between the air shaft 9 and the slider B16. An iron plate 161 is mounted on the slider B16 at the end facing the electromagnet 17. A tensioning assembly A19 is mounted on the protective cover 2. The tensioning assembly A19 includes, but is not limited to, a spring rod A. The fixed end of the spring rod A is connected to the protective cover 2, and the movable end of the spring rod A is connected to the end of the slider B16 near the air shaft 9. An adjustment mechanism is mounted on the protective cover 2. In operation, the adjustment mechanism adjusts the current of the electromagnet 17 according to the descent height of the guide wheel C6.

[0017] It should be noted that the air shaft 9 is used in conjunction with an air pump.

[0018] In this embodiment, when it is necessary to thread the fishing line, the fishing line spool is clamped on the air shaft 9 to fix the fishing line spool. Then, the fishing line end is found, the pull rod 14 is pulled to increase the distance between the clamping plate 13 and the inner wall of the slide groove 121, forming a threading channel. The fishing line end is inserted into the threading channel, the pull rod 14 is released, and the clamping plate 13 slides back to its original position under the tension of the spring A15 and clamps the line end. Then, the slide 5 is pulled up to expose the slot 51, and the locking block 8 is pushed laterally to lock into the slot 51. At this time, the guide wheel C6 is in a high position. The crank is rotated, and the crank drives the lead screw 11 to rotate, thereby causing the slider A10 to slide. The slider A10 passes the line end through the crossbar and the clamping assembly from above the guide wheel A3 and guide wheel B4. The line end is removed from the output end of the guide wheel B4 and connected to the processing equipment. Then, the slider A10 slides back to its original position, the locking block 8 is pulled laterally, and the slide 5 is slowly lowered until the guide wheel C6 presses down on the fishing line. During the operation of the processing equipment, the fishing line is automatically pulled. If the fishing line is too slack, the guide wheel C6 and the carriage 5 will move downward. At this time, the adjustment mechanism will start and increase the coil current of the electromagnet 17. The attraction of the electromagnet 17 to the slider B16 will increase, and the frictional resistance of the brake pad 18 to the air shaft 9 will increase. The fishing line will gradually tighten. Since the air shaft 9 rotates with the protective cover 2 in a state of near-unresistance when the brake pad 18 is not engaged, the fishing line will not be overly taut.

[0019] Example 2

[0020] like Figure 1 and Figure 3 As shown, the present invention proposes a net-threading device for fishing net processing. Compared with Embodiment 1, the adjustment mechanism includes a sliding rheostat and a tensioning component B22. The sliding rheostat is electrically connected to the electromagnet 17. The sliding rheostat includes a sliding rheostat body 20 and a slider 21 for adjusting the resistance value of the sliding rheostat. The sliding rheostat body 20 is connected to the protective cover 2. Specifically, the sliding rheostat has a fixed end A and a slider. The two ends of the coil of the electromagnet 17 are electrically connected to the fixed end A and the slider 21, respectively. The slider 21 is located below the slide frame 5. The tensioning component B22 is set on the protective cover 2. The tensioning component B22 includes, but is not limited to, a spring rod B. The body of the spring rod B is connected to the protective cover 2, and the movable end of the spring rod B is connected to the bottom surface of the slider 21. The tensioning component B22 pushes the slider 21 to slide upward and reset, and the slider 21 slides downward. The resistance value of the sliding rheostat decreases, and the current of the electromagnet 17 increases. It should be noted that spring bar B is made of non-conductive material, or has an insulating material sprayed on the outside of a conventional spring bar.

[0021] In this embodiment, when the fishing line is too slack, the slide 5 and guide wheel C6 descend and press the fishing line down. The slide 5 presses down the slide plate 21, and the downward movement of the slide plate 21 reduces the working resistance of the sliding rheostat, increases the coil current of the electromagnet 17, and strengthens the magnetism of the electromagnet 17, thereby increasing its attraction to the slider B16. The spring rod A contracts more, and the brake block 18 presses against the outer wall of the air shaft 9 and increases the frictional force to restrict the rotation of the air shaft 9. Subsequently, the fishing line begins to tighten, and the fishing line lifts the guide wheel 6. Under the tension of the spring rod B, the slide plate 21 slides upward and gradually reduces the coil current of the electromagnet 17. The magnetic attraction of the electromagnet 17 gradually weakens, thereby reducing the frictional resistance of the brake plate 18 to the air shaft 9.

[0022] Example 3

[0023] like Figure 4 As shown, the present invention proposes a different structure for the adjusting mechanism of a fishing net processing device compared to Embodiment 1 or Embodiment 2. The adjusting mechanism includes a ranging probe 23 and a controller 24. A positioning plate 52 is set on the slide 5. The ranging probe 23 is set on the protective cover 2 and located below the positioning plate 52. The ranging probe 23 adopts, but is not limited to, a laser ranging sensor. The detection end of the ranging probe 23 faces the positioning plate 52. The controller 24 adopts a PLC controller. The controller 24 is set on the protective cover 2 and electrically connected to the ranging probe 23. The controller is electrically connected to the coil of the electromagnet 17 through the electrical signal output terminal. The controller controls the working current of the electromagnet 17 by adjusting the duty cycle or amplitude of the output signal.

[0024] In this embodiment, the height of the positioning plate 52 is detected by the ranging probe 23 to obtain the height of the positioning wheel C6 in the current state, thereby indirectly determining the tension of the fishing line. If the fishing line is too slack, the height of the positioning plate 52 will be lower. At this time, the controller 24 controls the coil current of the electromagnet 17 to increase, thereby increasing the attraction force of the electromagnet 17 on the iron plate 161, which in turn increases the frictional resistance between the brake pad 18 and the outer wall of the air shaft 9. Conversely, the frictional resistance between the brake pad 18 and the outer wall of the air shaft 9 decreases. Compared with the sliding rheostat, its service life is longer.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
