A fishing net machine pre-drawing line mechanism

Abstract

This utility model relates to the field of fishing net weaving technology, specifically to a pre-drawing mechanism for a fishing net machine. It features a main warp feed roller for conveying warp threads and a pre-drawing roller for pre-drawing the warp threads. The pre-drawing roller rotates a pre-drawing wheel, and a clamping slot is located below the pre-drawing wheel. A telescopic block is mounted on the pre-drawing wheel, and a sliding clamping block is positioned within the groove of the clamping slot. The telescopic block and the sliding clamping block work together to form a temporary clamp to hold the warp threads, providing a brief pulling force as the pre-drawing wheel rotates, achieving the pre-drawing effect. The telescopic block is slidably connected within the pre-drawing wheel. When the pre-drawing wheel rotates to the lower position of the telescopic block, it automatically descends and extends under its own weight, pressing against the sliding clamping block. Furthermore, clamping block magnets and telescopic block magnets are respectively located at the top of the sliding clamping block and the bottom of the telescopic block, ensuring that both can clamp the warp threads.

Description

Technical Field

[0001] This utility model relates to the field of fishing net weaving technology, and in particular to a pre-drawing mechanism for a fishing net machine. Background Technology

[0002] Modern fishing nets are generally woven using double-hook net-weaving machines, which interweave warp and weft threads. The double-hook machine uses an upper hook to bend the warp threads into loops, while the lower hook pulls the weft threads out of the loops to form knots. To ensure all warp threads maintain synchronized and uniform tension, and to ensure the warp groups are strictly aligned at the perforation plate, preventing single warp threads from slack and causing the hooks to fail to thread accurately or the knots to unravel, the warp threads of the fishing net need to be pre-drawn.

[0003] Currently, most fishing net machines use various types of swing arms to draw the warp threads for pre-drawing. However, this type of swing arm pre-drawing mechanism not only occupies a lot of space, but also causes slight shaking of the equipment or some components when the swing arm swings, which in turn has some adverse effects on the stability of the warp and weft threads. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a pre-drawing mechanism for fishing net machines, so as to solve the technical problems of existing swing arm type pre-drawing mechanisms occupying a large space and being prone to shaking.

[0005] To achieve the above objectives, this utility model provides a pre-drawing mechanism for a fishing net machine, including a support frame and a main warp feed roller rotatably connected to the support frame for drawing warp threads. The pre-drawing mechanism further includes: A pre-pulling roller is rotatably connected to the bracket. Several pre-pulling wheels are fixedly connected to the pre-pulling roller, and a clamping block groove is provided below each pre-pulling wheel. A sliding clamping block is slidably connected in the groove of the clamping block slot. A telescopic block that can extend and retract is provided on the outer wall of the pre-extraction wheel. A clamping block magnet and a telescopic block magnet that can attract each other are respectively provided on the top of the sliding clamping block and the bottom of the telescopic block. The warp is located between the sliding clamping block and the telescopic block.

[0006] Furthermore, the support is also rotatably connected to an intermediate warp feed roller, which is located between the main warp feed roller and the pre-drawing roller, and the warp thread is wound around the intermediate warp feed roller at least once.

[0007] Furthermore, the support is equipped with multiple drive mechanisms, which are used to drive the main warp feed roller, intermediate warp feed roller and pre-drawing roller to rotate.

[0008] Furthermore, the pre-drawing rotating wheel is provided in multiple ways, and the clamping block groove and sliding clamp are also provided in multiple ways and correspond one-to-one, and the number of pre-drawing rotating wheels is consistent with the number of warp threads in the fishing net.

[0009] Furthermore, a sliding connecting rod is fixedly connected inside the groove of the clamping block slot, and the sliding clamping block is sleeved on the sliding connecting rod and slidably connected to it.

[0010] Furthermore, a return spring is provided on each side of the sliding clamping block. The return spring is sleeved on the sliding connecting rod, and the two ends of the return spring are respectively fixedly connected to the sliding clamping block and the clamping block groove.

[0011] Furthermore, the pre-extraction wheel is provided with a movable groove, and the inner end of the telescopic block is slidably connected in the movable groove.

[0012] Furthermore, the bottom of the telescopic block is covered with a layer of rubber pad.

[0013] The beneficial effects of this utility model are as follows: 1. A main warp feed roller is set to transport the warp threads, and a pre-drawing roller is set to pre-draw the warp threads. In addition, an intermediate warp feed roller is set between the main warp feed roller and the pre-drawing roller to ensure the smooth and orderly transport of the warp threads throughout the entire process.

[0014] 2. The pre-drawing roller rotates with the pre-drawing wheel, and a clamping block groove is set below the pre-drawing wheel. The pre-drawing wheel is equipped with a telescopic block, and a sliding clamping block is set in the groove of the clamping block. The telescopic block and the sliding clamping block cooperate to form a temporary clamp to hold the warp thread, and as the pre-drawing wheel rotates, it can provide a short-term pulling force to the warp thread to achieve the pre-drawing effect.

[0015] 3. The telescopic block is slidably connected in the pre-drawing roller. When the pre-drawing roller rotates to the lower position of the telescopic block, the telescopic block will automatically descend and extend under its own gravity and press against the sliding clamping block. In addition, clamping block magnets and telescopic block magnets that can attract each other are respectively provided at the top of the sliding clamping block and the bottom of the telescopic block to ensure that the warp threads can be clamped.

[0016] 4. A return spring is provided on the clamping block slot. After the pre-extraction wheel rotates and forces the telescopic block and the sliding clamping block to separate, the return spring can return the sliding clamping block to its initial position, making it convenient to perform the next clamping and pre-extraction operation.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0025] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, since the warp threads of fishing nets need to be pre-drawn, and current fishing net machines generally use various types of swing arms for pre-drawing the warp threads, the swing arm type pre-drawing mechanism has the problems of occupying a lot of space and being prone to shaking. Therefore, this utility model has made an improved design.

[0026] Specifically, a main warp feed roller 103 is rotatably connected to the support 101 for feeding the warp thread 01. A pre-feeding roller 105 is also rotatably connected to the support 101. Several pre-feeding rollers 107 are fixedly connected to the pre-feeding roller 105, and a clamping block groove 108 is provided below each pre-feeding roller 107. A sliding clamping block 110 is provided within the groove of the clamping block groove 108, and the sliding clamping block 110 is slidably connected within the groove of the clamping block groove 108. Additionally, a telescopic block 114 is provided on the outer wall of the pre-feeding roller 107. A clamping block magnet 112 and a telescopic block magnet 115 that can attract each other are respectively provided at the top of the sliding clamping block 110 and the bottom of the telescopic block 114. The warp thread 01 is located between the sliding clamping block 110 and the telescopic block 114.

[0027] The pre-drawing roller 105 rotates the pre-drawing wheel 107, and a clamping block groove 108 is set below the pre-drawing wheel 107. A telescopic block 114 is set on the pre-drawing wheel 107, and a sliding clamping block 110 is set in the groove of the clamping block groove 108. The telescopic block 114 and the sliding clamping block 110 cooperate to form a temporary clamp to hold the warp thread 01, and as the pre-drawing wheel 107 rotates, it can provide a brief pulling force to the warp thread 01 to achieve the pre-drawing effect.

[0028] Preferably, the support 101 is also rotatably connected to an intermediate warp feed roller 104, which is located between the main warp feed roller 103 and the pre-drawing roller 105, and the warp thread 01 is wound around the intermediate warp feed roller 104 at least once. This is to make the warp thread 01 transport process more smoothly and orderly.

[0029] The rotation of the main warp roller 103, the intermediate warp roller 104, and the pre-drawing roller 105 is all driven by the drive mechanism 102 mounted on the bracket 101.

[0030] The second aspect of this utility model is as follows: Figure 1 , Figure 3 and Figure 4 As shown, there are multiple pre-drawing rollers 107, and multiple clamping block grooves 108 and sliding clamping blocks 110 are also provided in a corresponding manner, and the number of pre-drawing rollers 107 is consistent with the number of warp threads 01 used to weave the fishing net.

[0031] Additionally, a sliding connecting rod 109 is fixedly connected within the groove of the clamping block slot 108, and a sliding clamping block 110 is sleeved on and slidably connected to the sliding connecting rod 109. A return spring 111 is provided on each side of the sliding clamping block 110, sleeved on the sliding connecting rod 109, with both ends of the return spring 111 fixedly connected to the sliding clamping block 110 and the clamping block slot 108, respectively. After the pre-extraction wheel 107 rotates, forcing the telescopic block 114 and the sliding clamping block 110 to disengage, the return spring 111 allows the sliding clamping block 110 to return to its initial position, facilitating the next clamping and pre-extraction operation.

[0032] Additionally, the pre-drawing roller 107 has a movable groove 113, and the inner end of the telescopic block 114 is slidably connected within the movable groove 113. When the pre-drawing roller 107 rotates to the position of the telescopic block 114 at the lower side, the telescopic block 114 will automatically descend and extend under its own gravity and press against the sliding clamping block 110. Furthermore, clamping block magnets 112 and telescopic block magnets 115 that can attract each other are respectively provided at the top of the sliding clamping block 110 and the bottom of the telescopic block 114, ensuring that the two can clamp the warp thread 01.

[0033] Preferably, the bottom of the telescopic block 114 is covered with a layer of rubber pad 116. Each time the telescopic block 114 descends and extends to cooperate with the sliding clamping block 110 to clamp the warp 01, there will be an impact force that causes a slight collision. In order to protect the warp 01, the clamping block magnet 112 and the telescopic block magnet 115, the rubber pad 116 is provided for cushioning.

[0034] After the telescopic block 114 and the sliding clamp 110 are engaged and connected, the pre-drawing wheel 107 continues to rotate, allowing the telescopic block 114 to carry the sliding clamp 110 to make a certain displacement. The speed of this displacement is greater than the normal feeding speed of warp 01. As the pre-drawing wheel 107 continues to rotate, the telescopic block 114 will eventually disengage from the sliding clamp 110, thus ending the pre-drawing operation.

[0035] Subsequently, as the pre-extraction wheel 107 continues to rotate and the telescopic block 114 rises, it will fall into the movable groove 113 under its own gravity. The sliding clamp 110 will be reset under the action of the reset spring 111. After the telescopic block 114 rotates one revolution again, it will fall back down and connect with the sliding clamp 110, thus starting a new pre-extraction operation.

[0036] In summary, this utility model sets a main warp feed roller 103 to transport the warp yarn 01, and a pre-drawing roller 105 to pre-draw the warp yarn 01. An intermediate warp feed roller 104 is also set between the main warp feed roller 103 and the pre-drawing roller 105 to ensure smooth and orderly transport of the warp yarn 01 throughout the entire process. The pre-drawing roller 105 rotates the pre-drawing turntable 107, and a clamping block groove 108 is set below the pre-drawing turntable 107. A telescopic block 114 is set on the pre-drawing turntable 107, and a sliding clamping block 110 is set in the groove of the clamping block groove 108. The telescopic block 114 and the sliding clamping block 110 cooperate to form a temporary clamp to hold the warp yarn 01, and as the pre-drawing turntable 107 rotates, it provides a brief pulling force to the warp yarn 01, achieving the pre-drawing effect.

[0037] The telescopic block 114 is slidably connected in the pre-drawing roller 107. However, when the pre-drawing roller 107 rotates to the lower position of the telescopic block 114, the telescopic block 114 will automatically descend and extend under its own gravity and press against the sliding clamping block 110. In addition, clamping block magnets 112 and telescopic block magnets 115 that can attract each other are respectively provided at the top of the sliding clamping block 110 and the bottom of the telescopic block 114, ensuring that the two can clamp the warp thread 01. A return spring 111 is provided on the clamping block groove 108. After the pre-drawing roller 107 rotates and forces the telescopic block 114 and the sliding clamping block 110 to separate, the return spring 111 can return the sliding clamping block 110 to its initial position, which is convenient for the next clamping and pre-drawing operation.
