Description

Technical Field

[0001] This utility model relates to the technical field of fishing net production and processing, and more specifically, to a line-laying device for fishing net production. Background Technology

[0002] In fishing net production, the process of releasing yarn from a spool of raw material (such as nylon or polyethylene) and weaving or knotting it according to a predetermined pattern to form a net is crucial. This fundamental step directly determines the strength, mesh size, and overall quality of the fishing net.

[0003] Currently, in the process of releasing lines for fishing net production:

[0004] The tension control of the fishing net line is unstable during the line-laying process, which can easily lead to the fishing net line becoming loose or overstretched, affecting the quality of the finished fishing net. At the same time, the line-laying speed is difficult to control precisely, and it is not coordinated with the subsequent weaving equipment, which can easily cause production interruption or material waste.

[0005] Therefore, in view of this, we have studied and improved the existing structure to provide a fishing net production line-laying device, in order to achieve a more practical purpose. Utility Model Content

It can avoid excessive stretching or even breakage of the line due to excessive tension, significantly improve the strength consistency and quality stability of the finished fishing net, and at the same time, ensure the line-laying speed and reduce production interruptions or material waste caused by speed mismatch.

[0008] 2. Technical Solution

[0011] A fixing plate is fixedly installed between the two wing ends of the T-shaped main support, and a sliding rod is fixed between the two fixing plates. Two pulleys with brackets slide on the sliding rod, and the fishing net line passes between the two pulleys with brackets. A support column is fixedly installed in the middle of the sliding rod, and the bottom end of the support column is fixed to the T-shaped main support. A spring is fixed between the support column and the pulleys with brackets, and the spring is movably sleeved on the side of the sliding rod.

[0019] 3. Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] ① This solution utilizes an intelligent clamping mechanism consisting of two pulleys with supports, driven by electric telescopic rods and buffered by springs. This mechanism dynamically adjusts the clamping pressure on the fishing net line. This effectively prevents the line from becoming loose or tangled due to insufficient tension during the release process, and also avoids excessive stretching or even breakage of the line due to excessive tension, significantly improving the strength consistency and quality stability of the finished fishing net.

[0022] ②In this solution, the friction force of the clamping mechanism on the fishing net line is adjustable. By controlling the extension and retraction of the electric telescopic rod, the resistance of the pulley on the line can be changed, thereby indirectly adjusting the line release speed so that it can be synchronized with the braiding or knotting equipment at the rear end, reducing production interruptions or material waste caused by speed mismatch.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Example:

[0037] Please see Figure 1 - Figure 4 A fishing net production line-laying device includes a T-shaped main support 1, a fixed baffle 101 fixedly installed on the handle end of the T-shaped main support 1, a winding wheel 2 movably installed on the fixed baffle 101 via a bearing, a fishing net line reel 3 being engaged with the winding wheel 2, and fishing net line being wound on the fishing net line reel 3.

[0038] A fixing plate 4 is fixedly installed between the two wing ends of the T-shaped main support 1. A sliding rod 5 is fixed between the two fixing plates 4. Two pulleys 6 with brackets slide on the sliding rod 5. The fishing net line passes between the two pulleys 6 with brackets. A support column 501 is fixedly installed in the middle of the sliding rod 5. The bottom end of the support column 501 is fixed to the T-shaped main support 1. A spring 502 is fixed between the support column 501 and the pulleys 6 with brackets. The spring 502 is movably sleeved on the side of the sliding rod 5. An electric telescopic rod 7 is fixedly installed between the side of the pulleys 6 with brackets and the fixing plate 4.

[0039] See Figure 1 , Figure 2 Specifically, a threaded post 201 is fixedly installed on one side of the winding wheel 2, and the threaded post 201 is threadedly connected to a movable baffle 202;

[0040] The radius of the movable baffle 202 is smaller than the radius of the fixed baffle 101.

[0041] The threaded connection between the threaded post 201 and the movable baffle 202 facilitates the installation or removal of the movable baffle 202, thereby making it easier to replace the fishing net line reel 3 that winds the fishing net line.

[0042] Specifically, the winding wheel 2 has two slots 203 on its side, and the two slots 203 are centrally symmetrical about the central axis of the winding wheel 2.

[0043] The fishing net reel 3 with a locking block is selected, which can be locked into the position of the locking slot 203, so that the fishing net reel 3 and the winding reel 2 can rotate synchronously.

[0044] Specifically, threaded holes are provided at the handle end and the two wing ends of the T-shaped main bracket 1, and positioning bolts 102 are threadedly connected to the threaded holes.

[0045] The positioning bolts 102 allow the entire device to be easily installed on a frame or a stable platform, thus enabling its combined use with other devices.

[0046] See Figure 1 , Figure 3 Specifically, the inner wall of the pulley groove of the pulley with bracket 6 is fitted with a smooth, wear-resistant bushing 601.

[0047] The wear-resistant bushing 601 reduces frictional resistance when the fishing net line passes through, prevents wear on the fishing net line, and extends the service life of the fishing net line and pulley.

[0048] See Figure 1 , Figure 3 , Figure 4 Specifically, when the two pulleys with brackets 6 are close together, the distance between the grooves of the two pulleys is less than the diameter of the fishing net line.

[0049] In this way, with the two pulleys 6 with brackets close together, it can be ensured that the pulleys 6 with brackets exert sufficient pressure on the fishing net line. By controlling the position of the two pulleys 6 with brackets through the two electric telescopic rods 7 respectively, the pressure of the pulleys 6 with brackets on the fishing net line can be adjusted, thereby ensuring that the fishing net line is in a taut state when being released. At the same time, by using the change in pressure value, the speed of the fishing net line when being released can be controlled to a certain extent.

[0050] Specifically, spring 502 is a compression spring, which is always in a compressed state;

[0051] The spring 502 always provides pressure, which slows down the extension speed of the electric telescopic rod 7 as it extends, thereby preventing the fishing net line from being damaged by excessive compression.

[0052] Pressure sensors can be hidden and fixed on both sides of the support column 501. The pressure sensors are in contact with the spring 502. When the detected pressure value is too high, the electric telescopic rod 7 can be controlled to extend slowly. The pressure value can also be used to determine whether the pressure of the pulley with bracket on the fishing net line is appropriate, so that the fishing net line is under the appropriate pressure value, ensuring that the fishing net line is taut and that the speed of releasing the fishing net line is appropriate.

[0053] Working principle:

[0054] At the start of the line-laying operation, the fishing net line reel 3, wound with fishing net line, is engaged with the slot 203 of the winding reel 2 via a locking block, achieving synchronous rotation. The line end is pulled out from the reel and passes through the gap between the two pulleys 6 with supports.

[0055] During core tension control: Two pulleys 6 with supports slide on the slide rod 5. Their positions are controlled by the extension and retraction of the electric telescopic rod 7 and are elastically supported by the spring 502. In the initial state, under the combined action of the electric telescopic rod 7 and the spring 502, the two pulleys are pushed towards the middle, making the distance between them smaller than the diameter of the fishing net line, thereby clamping the fishing net line.

[0056] When active speed adjustment is required: the basic distance between the two pulleys can be directly changed by controlling the extension or retraction of the electric telescopic rod 7. Extending the electric telescopic rod 7 will increase the clamping force and cause the unloading speed to decrease, while retracting it will decrease the clamping force and cause the unloading speed to increase, thereby achieving active matching with the subsequent production rhythm.

[0057] Throughout the process, the fishing net line slides across the wear-resistant bushing 601, minimizing wear. Ultimately, this electromechanical integrated intelligent feedback clamping mechanism achieves precise, stable, and controllable release of the fishing net line tension and speed, ensuring high-quality continuous production of fishing nets.

[0058] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
