Description

Technical Field

[0002] Nylon aquaculture net is a mesh material woven from synthetic fibers such as nylon, polyamide, and polyethylene. It is widely used in aquaculture, agricultural protection, and other fields. However, after production, existing nylon aquaculture nets need to be tested for surface viscosity. The current mainstream viscosity test method is to adhere a silicone plate with a tree frog foot pad structure to the nylon aquaculture net. The silicone plate with the tree frog foot pad structure adhered to the nylon aquaculture net is then peeled off. By observing the tensile force when peeling off the silicone plate, the surface viscosity strength of the nylon aquaculture net is determined, and then whether it meets the standard is determined. After testing the nylon breeding net, the existing nylon breeding net viscosity testing device needs to be manually collected and the nylon breeding net needs to be manually cut during collection, which increases the labor intensity of the workers. In addition, the existing nylon breeding net viscosity testing device mostly selects a fixed position for testing during testing, which leads to its great limitations and thus the detection data is not comprehensive enough.

[0014] Compared with the prior art, the present invention provides a surface viscosity testing device for aquaculture net production, which has the following beneficial effects: 1. In the present invention, during the test, the nylon breeding net is passed through the conveying roller group and then wound on the winding roller. Then, the viscosity testing mechanism is used to test the viscosity of the nylon breeding net below the viscosity testing mechanism. The operation of the viscosity testing mechanism drives the guide rod to move downward. After the guide rod moves downward, it contacts the rack and drives the rack to move downward. After the viscosity testing mechanism completes the test and resets, the guide rod and the rack are reset. During the reset process of the rack, the winding assembly is driven. The winding assembly operates to drive the winding roller to rotate one circle. At this time, the nylon breeding net that has been tested below the viscosity testing mechanism is wound up, and at the same time, the winding roller conveys another section of nylon breeding net to the viscosity testing mechanism. The viscosity testing mechanism is then driven to operate. Similarly, the viscosity testing mechanism detects the nylon breeding net, and after the viscosity testing mechanism is reset, the winding roller will reel up the tested nylon breeding net again, and transport the other untested nylon breeding net to the bottom of the viscosity testing mechanism. With the continuous rotation of the viscosity testing mechanism and the winding roller, the viscosity of the nylon breeding net can be tested while different positions of the nylon breeding net can be tested, thereby improving the detection range, and the winding roller can also reel and store the nylon breeding net after testing, thereby further improving practicality.

[0015] 2. In the present invention, as more and more nylon breeding nets are wound on the winding roller, the diameter of the winding roller will continue to increase. During this process, the nylon breeding net wound on the winding roller is gradually driven to push and rotate. The pushing component drives the cutting knife to move toward the nylon breeding net. Then, the cutting electric push rod drives the cutting knife to cut the nylon breeding net. Therefore, when the winding roller reaches saturation, the nylon breeding net can be automatically cut off, thereby improving the convenience of use.

[0016] 3. In the present invention, during detection, the conveying roller group can tension the nylon breeding net. At the same time, when the winding roller is reeling, the conveying roller group can also convey the nylon breeding net, thereby achieving the effect of tensioning and conveying, thereby greatly improving the subsequent detection effect of the nylon breeding net.

DETAILED DESCRIPTION

[0019] 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.

[0020] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a surface viscosity testing device for aquaculture net production.

[0021] Example 1: Please refer to Figures 1-11 A surface viscosity testing device for aquaculture net production includes a testing platform 1, on which are provided several groups of linked conveying rollers 2, a winding roller 3 and a viscosity testing mechanism 4, the winding roller 3 being used to wind up the nylon aquaculture net, and the viscosity testing mechanism 4 being used to perform viscosity testing on the nylon aquaculture net; The inspection platform 1 is also provided with a winding mechanism 5 and a cutting mechanism 6. The winding mechanism 5 includes a guide rod 51, a rack 52 and a winding assembly 53. The winding assembly 53 is used to drive the winding roller 3 to rotate. When the guide rod 51 moves downward, it can drive the rack 52 to move downward. When the rack 52 is reset, it can drive the winding assembly 53 to operate. The cutting mechanism 6 includes a pushing assembly 61, a cutting knife 62 and a cutting electric push rod 63. The pushing assembly 61 is used to drive the cutting knife 62 to move toward the nylon breeding net. The cutting knife 62 is used to cut the nylon breeding net. The cutting electric push rod 63 is used to drive the cutting knife 62 to move horizontally along the detection platform 1.

[0022] When in use, the nylon breeding net is passed through the conveying roller group 2 and wound on the winding roller 3, and then the viscosity testing mechanism 4 is used to test the viscosity of the nylon breeding net below the viscosity testing mechanism 4. The operation of the viscosity testing mechanism 4 drives the guide rod 51 to move downward, and the guide rod 51 contacts the rack 52 after moving downward, and drives the rack 52 to move downward. After the viscosity testing mechanism 4 completes the detection and reset, the guide rod 51 and the rack 52 are reset. During the reset process of the rack 52, the winding component 53 is driven to operate, and the winding component 53 operates to drive the winding roller 3 to rotate one circle. At this time, the nylon breeding net that has been tested under the viscosity testing mechanism 4 is wound up, and at the same time, the winding roller 3 conveys another section of nylon breeding net to the bottom of the viscosity testing mechanism 4, and then drives the viscosity testing mechanism 4 to operate. Similarly, the viscosity testing mechanism 4 detects the nylon breeding net, and after the viscosity testing mechanism 4 is reset, the winding roller 3 will detect it again The nylon breeding net that has been tested is rolled up, and the other section of nylon breeding net that has not been tested is transported to the bottom of the viscosity testing mechanism 4. With the continuous operation of the viscosity testing mechanism 4 and the winding roller 3, a comprehensive test of the nylon breeding net is achieved. As more and more nylon breeding nets are wound on the winding roller 3, the diameter of the winding roller 3 will continue to increase. In this process, the nylon breeding net wound on the winding roller 3 gradually drives the pushing component 61 to operate, and the pushing component 61 drives the cutting knife 62 to move toward the nylon breeding net. Then the electric push rod 63 is cut off to drive the cutting knife 62 to cut the nylon breeding net, thereby realizing the viscosity test of the nylon breeding net and improving the detection range of the nylon breeding net. The nylon breeding net that has been tested can also be rolled up to facilitate subsequent collection. At the same time, when the winding roller 3 is saturated, the nylon breeding net can be automatically cut off, thereby improving the convenience of use.

The guide rod 51 is fixedly connected to one end of the base 42. The winding roller 3 is fixedly connected to the mounting plate 31. The mounting plates 31 are distributed at both ends of the winding roller 3. An inner hole is opened on the mounting plate 31. The inner side of the inner hole is fixedly connected to a clamping spring 32. The end of the clamping spring 32 away from the inner hole is fixedly connected to a splint 33. The splint 33 is distributed above the winding roller 3. One end of the winding roller 3 is fixedly connected to a key shaft 34. The outer side of the key shaft 34 is plugged with a key slot 35. The keyway 35 is provided on the worm gear 533. The end of the winding roller 3 away from the key shaft 34 is provided with an array of rollers 36 arranged in a circumferential manner. The rollers 36 are rollingly connected to the inner groove 37. The inner groove 37 is provided at the end of the shaft frame 531 away from the worm gear 533. The end of the shaft frame 531 away from the worm gear 533 is fixedly connected to the bracket 38. A limiting groove 39 is provided on the inner side of the bracket 38. The inner side of the limiting groove 39 is slidably connected to the symmetrically distributed clamping blocks 310. The inner side of the clamping blocks 310 is threadedly connected to the bidirectional screw 311, and the bidirectional screw 311 is rotatably connected to the bracket 38. Before testing, insert the key shaft 34 at one end of the winding roller 3 into the key groove 35 in the worm gear 533, then place one end of the roller 36 on the winding roller 3 in the inner groove 37, then rotate the bidirectional screw 311, the bidirectional screw 311 rotates to drive the clamping block 310 to move along the limit groove 39, the clamping block 310 moves to fix the other end of the winding roller 3, then pull the splint 33 to separate the splint 33 from the winding roller 3, the splint 33 moves to squeeze the clamping spring 32, then pass the nylon breeding net through the conveying roller group 2 and place it between the splint 33 and the winding roller 3, then through the clamping The spring 32 and the splint 33 fix one end of the nylon breeding net, and then the electric push rod 41 is tested to drive the base 42 to move downward, and the base 42 moves downward to drive the roller 44 and the guide rod 51 to move downward, and the guide rod 51 moves downward to drive the rack 52 to move downward along the limit hole 538, and the guide rod 51 and the rack 52 move downward to squeeze the winding spring 539 and drive the winding gear 536 to rotate. Since a ratchet structure 535 is provided between the winding gear 536 and the worm 534, when the rack 52 moves downward, the winding gear 536 cannot drive the worm 534 to rotate, and then the imitation tree frog foot pad structure on the roller 44 The silicone plate 45 contacts the nylon breeding net and is adsorbed on the nylon breeding net. Then, the test electric push rod 41 drives the roller 44 and the tree frog foot pad structure silicone plate 45 to reset, thereby peeling the tree frog foot pad structure silicone plate 45 from the nylon breeding net. Then, by recording the pulling force of the test electric push rod 41 when peeling the tree frog foot pad structure silicone plate 45 from the nylon breeding net, it is determined whether the surface viscosity of the nylon breeding net meets the requirements. When the test electric push rod 41 drives the tree frog foot pad structure silicone plate 45 to reset, the guide rod 51 is gradually separated from the rack 52. At this time, the rack The rack 52 moves upward under the push of the winding spring 539, and the upward movement of the rack 52 drives the winding gear 536 to rotate. At this time, the winding gear 536 drives the ratchet structure 535 to rotate. The rotation of the ratchet structure 535 drives the worm 534 to rotate. The rotation of the worm 534 drives the worm wheel 533 to rotate. The rotation of the worm wheel 533 drives the key slot 35 to rotate. The rotation of the key slot 35 drives the key shaft 34 to rotate. The rotation of the key shaft 34 drives the winding roller 3 to rotate. At this time, the winding roller 3 winds and collects the nylon breeding net that has completed the inspection. Thereafter, different positions of the nylon breeding net can be inspected in the same way.

[0024] Example 3, see Figures 1-11, which is different from the above-mentioned embodiment 2, is that the pushing component 61 includes a right-angle frame 611 and a cutting platform 616. The cutting platform 616 is fixedly connected to the detection platform 1, and a knife groove is provided on the cutting platform 616. A bent pipe 612 is fixedly connected to the right-angle frame 611. The inner ends of the bent pipe 612 are respectively slidably connected with a trapezoidal plate 613 and a knife holder 614. The bent pipe 612 is filled with hydraulic oil, and the hydraulic oil is distributed between the trapezoidal plate 613 and the knife holder 614. The trapezoidal plate 613 is distributed above the winding roller 3. A tension spring 615 is fixedly connected to the trapezoidal plate 613, and one end of the tension spring 615 away from the trapezoidal plate 613 is fixedly connected to the curved tube 612. A return spring 617 is fixedly connected to the tool holder 614, and one end of the return spring 617 away from the tool holder 614 is fixedly connected to the curved tube 612.

As the test progresses, more and more nylon breeding nets are wound on the winding roller 3, which also makes the diameter of the winding roller 3 larger. In this process, the nylon breeding net wound on the winding roller 3 will gradually come into contact with the trapezoidal plate 613. As the diameter of the winding roller 3 increases, the nylon breeding net wound on the winding roller 3 will drive the trapezoidal plate 613 to move toward the curved pipe 612. The trapezoidal plate 613 moves to squeeze the tension spring 615 and transmits the pressure to the tool holder 614 through the hydraulic oil. At this time, the tool holder 614 is extended out of the curved pipe 612. When the knife holder 614 extends out of the bent pipe 612, the return spring 617 will be stretched. The movement of the knife holder 614 drives the cutting knife 62 and the cutting electric push rod 63 to move. Then the cutting knife 62 presses the nylon breeding net down onto the cutting platform 616. Then the cutting electric push rod 63 drives the cutting knife 62 to move horizontally. At this time, the cutting knife 62 cuts the nylon breeding net. After that, after the winding roller 3 is disassembled, the trapezoidal plate 613 and the knife holder 614 will be reset under the drive of the tension spring 615 and the return spring 617 to prepare for the next cutting.

The high conveying roller group 21 is provided with a driving wheel and a driving motor, and the driving motor is used to drive the driving wheel to rotate. The low conveying roller group 22 is provided with a driven wheel, and the driving wheel and the driven wheel are transmission-connected. The nylon breeding net is passed through the high conveying roller group 21 and the low conveying roller group 22, so that the nylon breeding net is tensioned by the high conveying roller group 21 and the low conveying roller group 22. Then, the driving motor drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the transmission belt. At this time, the high conveying roller group 21 and the low conveying roller group 22 convey the nylon breeding net, thereby driving the cut nylon breeding net to a position close to the winding roller 3, so that the user can install one end of the nylon breeding net conveniently.
