Description

Technical Field

[0001] This utility model belongs to the field of fishhook production technology, specifically referring to a wire cutting device for fishhook production. Background Technology Fishhooks are the core tools used to suspend bait and attract fish when fishing. The first step in their production process is to precisely cut the raw steel wire into multiple segments of fixed length that meet the requirements of subsequent processing.

[0002] Most existing wire cutting devices for fishhook production only transport raw materials through a single-sided feeding roller or bottom limiting groove. The steel wire lacks bidirectional clamping and guidance during transport, especially when the wire diameter is thin, rigid, or the transport speed is high. This can easily lead to suspension, deviation, jumping, or even twisting, affecting the precise positioning of subsequent cutting stations and potentially causing scratches or localized deformation on the wire surface, reducing raw material utilization. Furthermore, uneven resistance during long-distance transport can cause jamming and stalling, hindering continuous production efficiency. More importantly, the lack of a fixing structure on both sides of the cutting blade during cutting causes the wire to easily shift or elastically deform in the cutting direction under pressure from the blade. This further exacerbates the deviation in the cutting position and can result in poor cut smoothness and burrs, severely impacting subsequent processing accuracy and the quality of the finished fishhook. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a wire cutting device for fishhook production, so as to at least partially solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model is as follows: This utility model proposes a wire cutting device for fishhook production, comprising: The support plate has a limiting groove on its upper surface; The cutting assembly includes a mounting plate, a cutter, and a pressure plate. The mounting plate is located above a support plate and is configured to move up and down above the support plate. The cutter is fixedly mounted on the lower surface of the mounting plate. The pressure plate is configured to slide vertically on the mounting plate. Two sets of pressure plates are symmetrically arranged on both sides of the cutter. In the initial state, the lower surface of the pressure plate is lower than the lower surface of the cutter. A conveyor belt is located on the discharge side of the cutting assembly along the wire conveying direction; A positioning plate is configured to slide above the conveyor belt, and a photoelectric sensor is provided below the positioning plate to detect the conveying position of the free end of the steel wire; The controller is electrically connected to the photoelectric sensor, the lifting drive mechanism of the mounting plate, and the power source of the wire conveyor, respectively. The cutting assembly and the feeding side of the positioning plate are each equipped with a set of guide rollers, which are located above the support plate and the conveyor belt, respectively.

[0005] Furthermore, a sliding rod is slidably provided through the mounting plate, the pressure plate is connected to the lower end of the sliding rod, and a spring is sleeved on the sliding rod, with both ends of the spring connected to the mounting plate and the pressure plate respectively.

[0006] Furthermore, a moving mechanism is provided above the conveyor belt. The moving mechanism includes a support, a moving motor, a moving screw, and a moving guide rod. The support is fixedly mounted above the conveyor belt bracket. The moving motor is fixedly mounted on the support. The moving screw is rotatably mounted on the support, and one end is connected to the output shaft of the moving motor. The moving guide rod is fixedly mounted on the support. One end of the positioning plate is connected to the moving screw by a thread, and the other end is slidably mounted on the moving guide rod.

[0007] Furthermore, both the cutting assembly and the positioning plate are equipped with height adjustment components. The height adjustment components include a fixed plate, a lifting cylinder, and a roller frame. The lifting cylinder is located on the fixed plate, the roller frame is located at the free end of the lifting cylinder, and the guide roller is rotatably mounted on the roller frame.

[0008] Furthermore, a through groove is provided on the support plate, and the groove is located directly below the cutter.

[0009] Furthermore, a wire collection basket is provided below the discharge end of the conveyor belt.

[0010] The technical solution provided by this utility model has the following beneficial effects: (1) By using the limiting groove of the guide roller and the support plate, and the guide roller and the conveyor belt to form a bidirectional clamping and guiding structure, the steel wire is effectively prevented from floating, shifting, jumping or twisting during the conveying process, ensuring that the steel wire moves stably along the preset path. (2) By using the pressure plates symmetrically set on both sides, the steel wire is contacted and continuously pressed and fixed before cutting, so as to prevent the steel wire from moving or elastically deforming under the pressure of the cutting knife. This solves the problem of cutting position deviation from the root, ensuring that the cutting cut of each section of steel wire is flat and burr-free, providing high-quality fixed-length steel wire for subsequent processing, and ensuring the quality of finished fish hooks.

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0015] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0016] See Figures 1-3In this embodiment, the present invention provides a wire cutting device for fishhook production, including a support plate 1, a cutting assembly, a conveyor belt 5, a positioning plate 6, and a controller. A limiting groove is formed on the upper surface of the support plate 1, the extending direction of the limiting groove being consistent with the wire conveying direction. The wire is conveyed onto the support plate 1, where the support plate 1 provides initial support, and the limiting groove limits the wire, causing it to move along the limiting groove. The cutting assembly includes a mounting plate 2, a cutter 3, and a pressure plate 4. The mounting plate 2 is located above the support plate 1 and is configured to rise and fall above the support plate 1. The cutter 3 is fixedly mounted on the lower surface of the mounting plate 2. The pressure plate 4 is configured to slide vertically on the mounting plate 2, and the pressure plate 4 is positioned on both sides of the cutter 3. Two sets are set up to press and fix both sides of the wire cutting position. In the initial state, the lower surface of the pressure plate 4 is lower than the lower surface of the cutter 3. When the mounting plate 2 descends above the support plate 1, it drives the cutter 3 and the pressure plate 4 to descend. Since the lower surface of the pressure plate 4 is lower than the lower surface of the cutter 3 in the initial state, the pressure plate 4 first contacts the wire and presses against the upper surface of the wire. As the mounting plate 2 continues to descend, the pressure plate 4 always presses against the wire until the cutter 3 descends to cut the wire. The conveyor belt 5 is set along the cutting assembly. The discharge side of the wire conveying direction is used to receive and convey fixed-length wires cut by the cutting component; the positioning plate 6 is configured to slide above the conveyor belt 5, and a photoelectric sensor is provided below the positioning plate 6 to detect the conveying position of the free end of the wire; the controller is electrically connected to the photoelectric sensor, the lifting drive mechanism of the mounting plate 2, and the wire conveying power source respectively. The controller adopts a PLC control circuit board, and its circuit structure and control logic are conventional technical means in this field; in use, by driving the positioning plate 6 to move, the length between the positioning plate 6 and the cutter 3 is the required cutting length of the fishhook. When the free end of the wire is conveyed to the bottom of the positioning plate 6, the photoelectric sensor senses the conveying position of the wire and transmits the signal to the controller. The controller then controls the wire conveying power source to stop feeding the wire and simultaneously starts the lifting drive mechanism of the mounting plate 2 to drive the cutter 3 to descend and complete the cutting; wherein, both the cutting component and the feeding side of the positioning plate 6 are provided with a set of guide rollers 7, which are located above the support plate 1 and the conveyor belt 5 respectively.

[0017] In practical use, the position of the positioning plate 6 above the conveyor belt 5 is adjusted according to the required cutting length of the fishhook, so that the distance between the positioning plate 6 and the cutter 3 in the cutting assembly precisely matches the target length, thus completing the setting of the fixed length parameter. The steel wire raw material is conveyed into the limiting groove of the support plate 1. With the assistance of the guide roller 7 on the feeding side of the cutting assembly and the positioning plate 6, the steel wire moves stably along the limiting groove and is gradually conveyed to the cutting area. When the free end of the steel wire moves to below the positioning plate 6, the photoelectric sensor detects the signal and transmits it to the PLC controller; the controller immediately controls the power source of the steel wire conveyor to stop, and at the same time drives the mounting plate 2 of the cutting assembly to descend. The pressure plate 4 first contacts and presses the steel wire, and the two sides of the cutter 3 are simultaneously fixed to prevent movement. After the mounting plate 2 continues to descend, the cutter 3 completes the cutting of the steel wire. The cut steel wire of the fixed length falls onto the conveyor belt 5 on the discharge side of the cutting assembly, where it is received and conveyed to the subsequent collection or processing station, completing a single wire cutting process. The above steps can be repeated to achieve continuous production.

[0018] As a specific embodiment, the cutting assembly also includes a cutting frame, which is mounted above the support plate 1. The cutting frame is equipped with a cutting cylinder, and the mounting plate 2 is connected to the free end of the cutting cylinder. The controller controls the extension and retraction of the cutting cylinder, which drives the mounting plate 2 to rise and fall, thereby completing the corresponding cutting action.

[0019] See Figure 3 and Figure 4 In this embodiment, a sliding rod 8 is slidably mounted on the mounting plate 2, and the pressure plate 4 is connected to the lower end of the sliding rod 8. A spring 9 is sleeved on the sliding rod 8, and the two ends of the spring 9 are connected to the mounting plate 2 and the pressure plate 4 respectively.

[0020] In use, thanks to the spring 9, when the pressure plate 4 presses against the steel wire, the elastic restoring force of the spring 9 applies a pressing force to the pressure plate 4, ensuring that the pressure plate 4 is stably pressed against the steel wire. After cutting is completed, when the mounting plate 2 drives the cutter 3 and the pressure plate 4 to rise, the spring 9 drives the slide rod 8 to slide upward along the mounting plate 2, causing the pressure plate 4 to rise and return to its original position.

[0021] See Figures 1-3 In this embodiment, a moving mechanism is provided above the conveyor belt 5. The moving mechanism includes a support 10, a moving motor 11, a moving screw 12, and a moving guide rod 13. The support 10 is fixedly installed above the support of the conveyor belt 5. The moving motor 11 is fixedly installed on the support 10. The moving screw 12 is rotatably installed on the support 10, and one end is connected to the output shaft of the moving motor 11. The moving guide rod 13 is fixedly installed on the support 10. One end of the positioning plate 6 is connected to the moving screw 12 by a thread, and the other end is slidably installed on the moving guide rod 13.

[0022] In practical use, the moving motor 11 is started to drive the moving screw 12 to rotate according to the required length of the fishhook wire. The rotation of the moving screw 12 and the guidance of the moving guide rod 13 can drive the positioning plate 6 to move, thereby adjusting the position of the positioning plate 6.

[0023] See Figures 1-4 In this embodiment, both the cutting component and the positioning plate 6 are equipped with height adjustment components. The height adjustment components include a fixed plate 14, a lifting cylinder 15 and a roller frame 16. The lifting cylinder 15 is located on the fixed plate 14, the roller frame 16 is located at the free end of the lifting cylinder 15, and the guide roller 7 is rotatably located on the roller frame 16.

[0024] As a specific embodiment, a guide rod is slidably provided through the fixed plate 14, and the roller frame 16 is connected to the guide rod.

[0025] In practical use, the lifting cylinder 15 drives the roller frame 16 to rise and fall, thereby driving the guide roller 7 to rise and fall. The distance between the guide roller 7 and the support plate 1, as well as between the guide roller 7 and the conveyor belt 5, is adjusted. The setting of the guide roller 7 improves the stability of the steel wire conveying. Furthermore, the setting of the guide rod enables the lifting cylinder 15 to drive the roller frame 16 to rise and fall stably and vertically.

[0026] See Figure 3 In this embodiment, a through-cut groove 17 is provided on the support plate 1. The through-cut groove 17 is located directly below the cutter 3. By setting the through-cut groove 17, the debris cut by the cutter 3 can fall from the through-cut groove 17. In a specific embodiment, a chip collection basket can be set below the corresponding slot 17 on the support plate 1.

[0027] See Figures 1-3 In this embodiment, a wire collection basket 18 is provided below the discharge end of the conveyor belt 5.
