Description

Technical Field

[0001] The present invention relates to the technical field of fishing net wire packaging equipment, and more specifically, to a fishing net production wire drawing and packaging equipment and method. Background Art

[0002] In fishing net production, wire drawing is the process of processing synthetic polymer materials into continuous, slender, single fibers with a certain strength and toughness, namely monofilaments, while winding is the process of neatly winding the shaped monofilaments onto a reel or bobbin to form a package suitable for subsequent twisting, warping and net weaving processes. Currently, monofilament packages for fishing nets are wound onto the outside of a spool using a lateral movement of the yarn guide. During this process, the continuous movement of the yarn guide repeatedly stretches or shortens the monofilament from the guide roller to the spool. As a result, the tension of this section of monofilament fluctuates repeatedly during winding, which can easily scratch the monofilament surface and cause uneven tension on the inner and outer layers of the spool after winding. In order to solve the above problems, the present application proposes a fishing net production drawing and packaging equipment and method. Summary of the Invention

[0003] The purpose of the present invention is to provide a fishing net production wire drawing and packaging equipment and method, which keeps the length of the monofilament between the pay-off roller and the winding roller constant by the overall lateral reciprocating movement of the winding roller, thereby solving the problem of repeated tension fluctuations when the monofilament is wound.

[0004] To solve the above technical problems, the present invention is achieved through the following technical solutions: A fishing net production wire drawing and winding equipment, comprising a machine body, a pay-off roller at the left end and a guide roller in a winding area, wherein a winding mechanism is provided in the winding area; The center of the winding mechanism is a fixed roller, which is fixed to the front side of the machine body through a fixed seat at its rear end. The outermost side of the fixed roller is provided with a winding drum. A transverse sleeve is slidably mounted on the outer side of the fixed roller in the front-to-back direction, a coaxial rotating sleeve is rotatably mounted on the outer side of the transverse sleeve, and the winding drum is detachably mounted on the outer side of the rotating sleeve; A support rod is rotatably mounted on the front end of the rotating sleeve, and an expansion pad on the outer side of the movable end of the support rod is detachably engaged with an open groove distributed circumferentially in the convex ring at the front end of the winding drum; A method for using a fishing net production wire drawing and packaging device is as follows: S1. When the fishing net monofilament passes through the guide roller and is wound on the outside of the winding drum, the transmission rod drives the lateral sleeve to move back and forth horizontally, thereby driving the winding drum to move horizontally repeatedly; S2. While the traverse sleeve is moving horizontally, the rotating sleeve is driven to rotate by the engagement of the rotating gear with the rotating frame, thereby driving the winding drum to repeatedly move horizontally while performing the winding operation; S3. When the take-up drum needs to be replaced, the support rod is moved to disengage it from the opening slot, and then the take-up drum is slid out for replacement.

[0005] Beneficial effects of the present invention: The present invention utilizes an inner, middle, and outer three-layer structure of a fixed roller, a traverse sleeve, and a rotating sleeve. When winding the monofilament, the reciprocating lateral movement of the traverse sleeve and the rotational movement of the rotating sleeve drive the winding drum to perform repeated lateral movement and coordinated rotational movement, thereby maintaining a fixed path for the monofilament movement between the guide roller and the rotating sleeve, thereby ensuring stable tension, avoiding scratches caused by left-right swinging, and solving the problem of uneven tension in the inner and outer layers after winding, resulting in partial slack and partial tension. The winding drum of the present invention is assembled on the outside of the rotating sleeve in a sliding manner. By utilizing the clamping connection between the support rod and the expansion pad and the open groove, the rotating sleeve can be disassembled or installed in a short time, thereby reducing the overall downtime of the equipment, simplifying the operation process and reducing the difficulty of work, and is suitable for continuous operation in the production of fishing net wire drawing.

[0008] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0009] See also Figure 1 - Figure 8 As shown, the present invention provides a fishing net production drawing and winding equipment, comprising a body 11, a pay-off roller 12 at the left end, and a guide roller 13 in a winding area, wherein a winding mechanism is provided in the winding area; The winding mechanism is a four-layer structure composed of inner, middle and outer layers and a winding drum 23. The center of the winding mechanism is a fixed roller 22, which is fixed to the end surface of a fixed base 21 on the front side of the machine body 11 (the fixed base 21 is a machine housing with a built-in rotating motor, which is a mature commercial product on the market). The middle layer of the winding mechanism is a transverse sleeve 24, and the outer layer of the winding mechanism is a rotating sleeve 25. The winding drum 23 is located outside the rotating sleeve 25. The traverse sleeve 24 is mounted on the outside of the fixed roller 22 in a sliding manner in the front-to-back direction. The rotating sleeve 25 is rotatably mounted on the outside of the traverse sleeve 24 with the center of the traverse sleeve 24 as the rotation center. The winding drum 23 is detachably mounted on the outside of the rotating sleeve 25. A support rod 252 is rotatably installed at the front end of the rotating sleeve 25, which can rotate back and forth toward the side away from the axis of the rotating sleeve 25. An expansion pad 253 is fixed to the outer side of the movable end of the support rod 252. The silicone rubber structure is used. It automatically compresses and deforms inward under the extrusion of external force, and expands and resets after the external force disappears. The expansion pad 253 follows the support rod 252 and is detachably clamped to the open groove 232. The axis of the opening groove 232 is distributed inside the convex ring 231 at the front end of the winding drum 23. The circular groove part of the opening groove 232 is the clamping area, and the square opening area is located on the outside, which is the extrusion area, used to squeeze the expansion pad 253 inward and compress and deform it.

[0010] Furthermore, a side groove 251 is provided at the front end of the rotating sleeve 25, the end adjacent to the axis of the rotating sleeve 25 is a closed end, and the end facing forward and toward the outer circle is an open structure. A fixed shaft 254 is fixed inside the end of the side groove 251 away from the axis of the rotating sleeve 25, and the axis is perpendicular to the axis of the rotating sleeve 25. The fixed shaft 254 is rotatably installed on the fixed end of the support rod 252, and the side groove 251 is also used to accommodate the support rod 252 in the reset state.

[0011] Furthermore, a T-slot 214 is provided on the front side of the fixing base 21, and a rotating frame 26 is rotatably installed inside the front side of the fixing base 21, and is rotatably connected to the T-slot 214 through a T-block 262 protruding from the rear side thereof, wherein the T-slot 214 and the T-block 262 respectively surround the adjacent axial areas of the fixing base 21 and the rotating frame 26.

[0012] Furthermore, a rotating gear 211 is installed on the left side of the interior of the fixing base 21 and is meshed with the toothed structure on the outside of the rotating frame 26 . The rotating gear 211 is driven to rotate by a rotating motor built into the fixing base 21 .

[0013] Furthermore, an annular groove 221 is formed on the outer side of the fixed roller 22, and the front end thereof extends to the front end surface of the adjacent fixed roller 22. An inner protrusion 241 is fixed to the inner side of the rear end of the transverse sleeve 24, which is an annular structure and is sleeved on the outer side of the annular groove 221. Among them, through holes 2411 in the front-to-back direction are opened on both sides of the inner inner bulge 241, one of the through holes 2411 is a smooth hole body, which is connected to the guide rod 213 on the front side of the fixed seat 21, and the other through hole 2411 is transmission-connected to the transmission rod 212 on the other side of the front of the fixed seat 21 (the transmission rod is a ball screw on the market, which is driven to rotate by another rotating motor built into the fixed seat 21). The transmission rod 212 and the guide rod 213 are both located inside the annular groove 1 221, and their front ends are rotationally connected to the front end surface of the annular groove 1 221 (that is, the fixed roller 22).

[0014] Furthermore, a second annular groove 242 is provided on the outer side of the transverse sleeve 24, and the rotating sleeve 25 is rotatably installed in the second annular groove 242 through the inner inner ring block 255, and the rotating sleeve 25 is fixed to the outer side of the transverse sleeve 24 by means of the front and rear end surfaces to prevent lateral movement.

[0015] Furthermore, a connecting rod 261 extends from the front side of the rotating frame 26 and passes through the positioning holes 256 inside the rotating sleeve 25. It is evenly distributed circumferentially and is used to transmit the rotational power of the rotating frame 26 to drive the winding drum 23 to rotate and perform the winding operation of the fishing net monofilament.

[0016] like Figures 1-8 As shown, a method for using a fishing net production drawing and packaging equipment is as follows: S1. When the fishing net monofilament passes through the guide roller 13 and is wound around the outside of the winding drum 23, a rotary motor built into the fixed seat 21 is activated to drive the transmission rod 212 (a ball screw) to rotate. Utilizing the transmission connection between the transmission rod 212 and the through hole 2411 and the sliding connection between another through hole 2411 and another transmission rod 212 (a smooth rod), the traverse sleeve 24 is driven to move back and forth laterally around the outside of the fixed roller 22, thereby driving the outermost winding drum 23 to repeatedly move laterally. S2. While the traverse sleeve 24 is moving laterally, another rotary motor built into the fixed seat 21 drives the rotary gear 211 to rotate. Utilizing the meshing connection between the rotary gear 211 and the rotary frame 26 and the penetration of the connecting rod 261 through the positioning hole 256, the rotary frame 26 rotates, and the connecting rod 261 drives the rotary sleeve 25 to rotate, thereby driving the take-up drum 23 to rotate while repeatedly moving laterally (i.e., winding operation); S3. When the winding drum 23 needs to be replaced, the end of the support rod 252 is moved. When the support rod 252 passes through the square groove body (i.e., the opening part) of the opening groove 232, the expansion pad 253 located on the outside of the support rod 252 is squeezed by the inner wall of the square groove body and deformed inward, thereby reducing the maximum diameter of the support rod 252 and the expansion pad, so that the support rod 252 and the expansion pad 253 are separated from the opening groove 232, releasing the limit on the winding drum 23, and then the winding drum 23 is slid out and replaced. After the new winding drum 23 is installed, the support rod 252 is moved in the opposite direction to make it engage with the inside of the opening groove 232, and the expansion pad 253 is automatically pressed against the circular groove body wall of the opening groove 232 to form a limit, and then the winding operation of the fishing net monofilament can be carried out.

[0017] It can be understood that the present invention adopts the reciprocating lateral movement of the winding drum 23 to keep the length of the fishing net monofilament from the guide roller 13 to the winding drum 23 constant, avoiding the tension fluctuation caused by the left and right swinging of the fishing net monofilament during the winding operation, which can not only prevent the monofilament from being scratched, but also ensure the uniform tension of the wound fishing net monofilament roll, avoiding local relaxation and local tension. In addition, the winding drum 23 adopts a sliding and pulling method for rapid disassembly and assembly, which can shorten the downtime of the entire equipment and adapt to the continuous operation requirements of the fishing net monofilament drawing and winding.
