Description

Technical Field

[0001] This utility model relates to the field of fishing net manufacturing technology, specifically a mold for adjusting the uniformity of monofilament extrusion of fishing nets. Background Technology

[0002] Fisheries are a vital global economic sector, and fishing nets, as an indispensable material in fisheries production, directly affect the performance and lifespan of the nets, thus impacting fishing efficiency and costs. For fishing nets, the quality of the monofilaments is paramount. High-quality fishing nets should possess monofilaments with uniform diameter, good strength, flexibility, and abrasion resistance. Among these, the uniformity of monofilament diameter is one of the key factors influencing the quality of the fishing net.

[0003] However, the existing devices have the following problems:

[0004] The existing equipment mainly produces fishing lines by directly feeding the material into the extrusion die. However, during the manufacturing process, the pressure of the extrusion die suddenly decreases, resulting in different diameters of the fishing lines and affecting their quality.

[0005] Meanwhile, some devices lack a pressure detection mechanism inside the extrusion die, making it impossible to detect pressure changes inside the die in a timely manner and affecting the accuracy of pressure control.

[0006] Therefore, in order to solve the above problems, a mold for adjusting the uniformity of monofilament extrusion of fishing net line is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a mold for adjusting the uniformity of monofilament extrusion of fishing net lines, so as to solve the problems in the manufacturing of fishing net lines mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fishing net line monofilament extrusion uniformity adjustment mold, comprising an extrusion mold, an injection pipe, and a connecting pipe. The injection pipe is disposed on the outer side of the extrusion mold, and the connecting pipe is disposed on the outer side of the injection pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model injects raw material into the extrusion mold through the guide tube outside the regulating box. The pressure of the molten raw material pushes the extrusion ball, which in turn moves the pressure block inward. The pressure block moves the resistance regulating block, which in turn moves the connecting resistor. The resistance of the connecting resistor is adjusted, and the resistance change is detected. When the pressure of the extrusion mold is too low, the regulating motor is started. The regulating motor drives the gear to rotate, which in turn drives the rotating disk to rotate. The rotating disk moves the driving rod inward, which in turn moves the pressure rod inward, which in turn moves the pressure ball inward. This temporarily pressurizes the extrusion mold to maintain the stability of the internal pressure of the extrusion mold. The power of the injection pump is adjusted by the change in the resistance of the connecting resistor, thereby regulating the pressure change.

[0026] A uniformity adjustment mold for monofilament extrusion of fishing net line includes an extrusion mold 1, an injection pipe 2, and a connecting pipe 3. The injection pipe 2 is disposed on the outer side of the extrusion mold 1, and the connecting pipe 3 is disposed on the outer side of the injection pipe 2. An adjustment box 4 is fixedly connected to the outer side of the extrusion mold 1, and a pressure rod 403 is fixedly connected to the outer side of the adjustment box 4. A drive frame 5 is fixedly connected to the outer side of the extrusion mold 1, and an adjustment motor 505 is fixedly connected to the outer side of the drive frame 5. A detection barrel 6 is fixedly connected to the outer side of the extrusion mold 1, and a pressure block 603 is movably connected inside the detection barrel 6. A connection resistor 606 is fixedly connected inside the detection barrel 6.

[0027] Furthermore, a guide tube 401 is movably connected inside the regulating box 4, and an extrusion die 1 is fixedly connected to the outside of the guide tube 401. A pressure ball 402 is fixedly connected to the outside of the regulating box 4, and a pressure rod 403 is fixedly connected to the outside of the pressure ball 402. A driving rod 404 is fixedly connected to the outside of the pressure rod 403, and a rotating disk 502 is movably connected to the outside of the driving rod 404. By pushing the driving rod 404, the internal pressure of the extrusion die 1 can be adjusted.

[0028] Furthermore, a connecting block 501 is fixedly connected to the upper part of the drive frame 5, a rotating disk 502 is movably connected inside the drive frame 5, a drive gear 504 is movably connected to the outer side of the connecting block 501, an adjusting motor 505 is fixedly connected to the outer side of the drive gear 504, a rotating disk 502 is movably connected to the lower part of the drive gear 504, a guide groove 503 is provided on the outer side of the rotating disk 502, and a drive rod 404 is movably connected inside the guide groove 503. By starting the adjusting motor 505, the drive rod 404 can be pushed.

[0029] Furthermore, a detection rod 601 is fixedly connected inside the detection barrel 6, and an extrusion ball 602 is fixedly connected to the outside of the detection rod 601. A pressure block 603 is movably connected inside the detection rod 601, and a sealing ring 604 is fixedly connected to the outside of the pressure block 603. A resistance adjustment block 605 is fixedly connected to the outside of the pressure block 603, and a connecting resistor 606 is movably connected to the outside of the resistance adjustment block 605.

[0030] Working Principle: During operation, the raw material is first melted and injected into the injection pipe 303. The injection pump 202 is then activated, driving the injection tank 201 to inject the raw material into the regulating tank 4. The material is then injected into the extrusion die 1 through the guide pipe 401 on the outside of the regulating tank 4. The pressure of the melted raw material pushes the extrusion ball 602, which in turn moves the pressure block 603 inward. The pressure block 603 then moves the resistance regulating block 605, which in turn moves the connecting resistor 606. The resistance of the connecting resistor 606 is adjusted, and the connection is monitored. When the pressure of the extrusion die 1 is too low, the change in resistance of resistor 606 causes the start of the regulating motor 505. The regulating motor 505 drives the gear 504 to rotate, which in turn drives the rotating disk 502 to rotate. The rotating disk 502 then drives the rod 404 to move inward, which in turn drives the pressure rod 403 to move inward. The pressure rod 403 then drives the pressure ball 402 to move inward, temporarily pressurizing the extrusion die 1 to maintain the stability of the internal pressure of the extrusion die 1. By adjusting the power of the injection pump 202 through the change in resistance of resistor 606, the pressure change is regulated.
