Description

Technical Field

[0001] This utility model relates to the field of textile technology, and specifically to a silk spinning filament drawing device. Background Technology

[0002] The multi-strand to single-strand drafting of silk filaments is a core process in the production of high-end silk products. It requires coordinated operation across the entire process, including stable feeding, filament arrangement, precise drafting, and orderly winding. This necessitates ensuring the evenness and strength of the single-strand filaments while also adapting to the efficiency and multi-specification flexibility demands of industrial-scale mass production. However, current silk filament drafting equipment in the industry suffers from numerous technical deficiencies in structural design and functional adaptability, making it difficult to meet production needs. Specific problems include: 1. Traditional drawing equipment mostly adopts a single drawing mechanism and a single take-up and unload unit design, which can only process one thread of fine wire at a time, resulting in low production efficiency and failing to meet the needs of large-scale industrial production. 2. Traditional drawing equipment's pressure roller module is mostly an integrated fixed structure, and the contact area and clamping force between the pressure roller and the input rod cannot be flexibly adjusted: for fine denier filaments, an excessively large contact area of ​​the fixed pressure roller can easily lead to excessive local pressure and cause filament breakage; for medium and coarse filaments, insufficient contact area will result in uneven transmission of drawing force and the appearance of thick filaments that have not been fully drawn.

The drawing mechanism is provided with at least two sets, and each set of the drawing mechanism includes a fixed arm provided on the mounting frame and a rotating arm rotatably assembled at the end of the fixed arm.

The drive motor of this utility model can flexibly adjust the input rod speed according to the number of filament strands and wire diameter. The pressure roller module adjusts the bonding pressure through the rotating arm. It can adapt to the drawing of multi-strand silk filaments without replacing the core components, reducing the equipment investment cost for multi-specification production.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] The following is a description of the embodiments and appendices. Figures 1-7 The technical solution of this utility model will be further described below.

[0017] Example 1 A silk filament drawing device, comprising: The frame 10 includes a mounting frame 101, an assembly base 102 disposed on the mounting frame 101, a rotating base 103 disposed within the assembly base 102, and an input rod 104 rotatably disposed within the rotating base 103. The input rod 104 is provided with grooves 1041. The assembly base 102, the rotating base 103, and the input rod 104 are arranged in three groups from top to bottom. Each group of input rods 104 is connected to a drive motor 1042 on its outer side. The drawing mechanism 20 is provided with at least two sets, and each set of the drawing mechanism 20 includes a fixed arm 201 provided on the mounting frame 101 and a rotating arm 202 rotatably assembled at the end of the fixed arm 201. The rotating arm 202 is provided with a pressure roller module 1 203, a pressure roller module 204 and a pressure roller module 3 205 from top to bottom. The pressure roller module 1 203, the pressure roller module 204 and the pressure roller module 3 205 are respectively provided with three sets of input rods 104. The feeding and receiving mechanism includes a feeding module 301 disposed at the upper end of the stretching mechanism 20 and a receiving module 302 disposed at the lower end of the stretching mechanism 20. The feeding module 301 includes a feeding frame 3011 and a feeding roller core 3012 rotatably disposed on the feeding frame 3011. The receiving module 302 includes a receiving hopper 3021, a receiving shaft core 3022 disposed in the receiving hopper 3021, and a second drive motor 3023 disposed at the lower end of the receiving hopper 3021. The output end of the second drive motor 3023 can be connected to the lower end of the receiving shaft core 3022 for transmission.

[0018] like Figures 1-7 As shown, in actual use, this utility model: First, the roll of spun silk filaments wound with multiple strands is fixed on the feed roller core 3012 of the feed rack 3011. The free end of the filament is pulled out and guided through the pressure roller module 1 203 at the upper end of the drawing mechanism 20, then around the pressure roller module 204 and the pressure roller module 3 205 in sequence. Finally, the end of the filament is fixed on the take-up shaft core 3022 in the take-up hopper 3021. If the equipment is equipped with multiple drawing mechanisms 20, the above steps are repeated to complete the construction of each filament path, ensuring that each filament is free of tangling and the path is smooth. Next, start all drive motors 1042 to drive the three sets of input rods 104 to rotate around the rotating base 103. Observe the upper two sets of input rods 104 to smoothly convey the filaments, and the middle input rod 104 to organize the filament strands through the pressure roller module 204. After the input rod speed stabilizes, start drive motor 3023 to drive the take-up shaft 3022 to rotate and start winding the drawn single strand of filament. During the operation, observe the state of the filament. If slippage occurs, fine-tune the rotating arm 202 to increase the contact with the corresponding pressure roller. If filament breakage occurs, check the speed difference of the input rods or the pressure of the pressure rollers. After adjustment, re-thread the filament. If the filament winding on the take-up shaft 3022 is uneven, fine-tune the speed of drive motor 3023 to ensure that the take-up speed is synchronized with the drawing speed. Finally, after the material roll on the feed roller core 3012 is exhausted, first turn off the drive motor 1042. After the input rod 104 stops rotating, turn off the drive motor 2023, disassemble the single-strand filament roll on the take-up shaft core 3022, clean the filament debris remaining on the surface of the equipment, and check the wear of the pressure roller module and the groove of the input rod to prepare for the next operation.

[0019] This utility model has the following beneficial effects: 1. The drawing mechanism 20 is equipped with at least two sets, which can simultaneously draw multiple batches of silk filaments. Compared with a single set of drawing mechanisms, it is more suitable for industrialized mass production needs. Moreover, the parameters of each set of drawing mechanisms can be adjusted independently, and different specifications of filaments can be processed at the same time, with strong flexible production capabilities. 2. The three sets of input rods 104 are independently speed controlled by drive motor 1042. The upper two sets have similar speeds, which can organize the order of the filaments in the early stage of filament feeding and avoid excessive stretching and filament breakage caused by excessive speed difference. The lower input rod has a larger speed, which provides stable tension force for multiple filaments through speed difference, gradually stretching and merging them into a single strand, avoiding fiber damage caused by one-time strong stretching. 3. The drive motor 1042 can flexibly adjust the input rod speed according to the number of filament strands and wire diameter. The pressure roller module adjusts the bonding pressure through the rotating arm 202. It can adapt to the drawing of multi-strand silk filaments without replacing the core components, reducing the equipment investment cost for multi-specification production.

[0020] As a further preferred embodiment, the output end of the drive motor 3023 is provided with a connector 30231, and the lower end of the receiving shaft core 3022 is provided with a groove 30221, and the connector 30231 can be inserted into the groove 30221.

[0021] Specifically, the connector 30231 and the groove 30221 adopt a shape-matching design (such as square, D-shaped or spline structure). After insertion, they can form a tight circumferential limit with no relative sliding gap. When the filaments on the take-up shaft 3022 are full and need to be replaced, there is no need to disassemble complex parts such as bolts and couplings. Just take out the full take-up shaft, align the groove 30221 of the empty take-up shaft with the connector 30231 and insert it to complete the assembly. This greatly reduces the downtime for changing materials and improves the continuity of the drawing operation.

[0022] As a further preferred embodiment, a vacuum air duct 206 is provided at the upper end of the pressure roller module 205.

[0023] Specifically, the pressure roller module 3 205 corresponds to the high-speed input rod on the lower side. During the drafting process, the fine filaments are prone to loose hairs due to tension, and there may be tiny fiber debris adhering to the filament surface in the environment. The vacuum air groove 206 can adsorb the hairs, short fibers and impurities on the surface of the single strand of filament in real time through negative pressure adsorption, so as to avoid the hairs from getting tangled in the grooves 1041 of the pressure roller module 3 2053 or the input rod 104. At the same time, it reduces the amount of hairs on the surface of the finished filament, improves the smoothness and purity of the silk, and reduces the risk of yarn breakage caused by hair entanglement in subsequent weaving processes.

[0024] As a further preferred embodiment, the first pressure roller module 203 includes a connector 2031 disposed at the upper end of the rotating arm 202 and a first pressure roller assembly 2032 rotatably mounted on the connector 2031. The second pressure roller module 204 includes a second connector 2041 fixed to the middle of the rotating arm 202, a second pressure roller assembly 2042 rotatably mounted on the connector 2041, an adjustment component 2043 slidably mounted at the lower end of the rotating arm 202, and a limiting conveyor belt 2044 sleeved between the second pressure roller assembly 2042 and the adjustment component 2043. The third pressure roller module 205 includes a second sliding seat 2051 slidably mounted at the front end of the rotating arm 202, a third connector 2052 disposed at the front end of the second sliding seat 2051, and a third pressure roller assembly 2053 rotatably mounted on the third connector 2052.

[0025] Specifically, pressure roller modules 1 203, 204, and 3 205 correspond one-to-one with three sets of input rods 104, forming a continuous coordination of initial conveying, sorting and guiding, and core drafting. Pressure roller module 1 203 achieves stable feeding of multiple strands of fine filaments by rotating the assembled pressure roller wheel group 1 2032, in conjunction with the upper low-speed input rod, reducing conveying friction. Pressure roller module 2 204 relies on the limiting conveyor belt 2044 to pre-press and sort the fine filaments of the middle input rod, avoiding inter-strand entanglement. Pressure roller module 3 205, with the position adjustability of the sliding seat 2 2051, adapts to the drafting requirements of the lower high-speed input rod, covering the entire conversion process from multiple strands of fine filaments to a single strand. Drafting can be completed without additional equipment, making it suitable for industrial integrated production. The sliding seat 2051 of the pressure roller module 205 can slide along the rotating arm 202. Its position can be quickly fixed by adjusting the waist hole and locking bolt. The contact area between the pressure roller assembly 2053 and the lower input rod can be adjusted according to the drafting requirements of different wire diameters. For thicker wires, the contact area is increased to avoid excessive local pressure during high-speed drafting, which could lead to wire breakage. For thinner wires, the contact area is reduced to ensure uniform transmission of drafting force. Simultaneously, the adjusting component 2043 of the pressure roller module 204 can finely adjust the tension of the limiting conveyor belt 2044 to adapt to the processing requirements of different strand counts. Production specifications can be switched without replacing the entire pressure roller module, reducing equipment investment costs for multi-variety production.

[0026] As a further preferred embodiment, the adjustment assembly 2043 includes a sliding seat 20431, a connecting rod 20432, and a tensioning member 20433. The sliding seat 20431 is slidably mounted on the lower end of the rotating arm 202, and its side end is provided with an adjustment waist hole 204311. The side end of the rotating arm 202 is provided with a corresponding locking hole 2021. A locking bolt 20434 is threadedly connected to the locking hole 2021, and the threaded part of the locking bolt 20434 is slidably adapted to the adjustment waist hole 204311. The connecting rod 20432 is fixed below the sliding seat 20431, and the tensioning member 20433 is provided at the end of the connecting rod 20432 and abuts against the inner side of the limiting conveyor belt 2044.

[0027] Specifically, the adjusting component 2043, through the sliding engagement of the sliding seat 20431 and the adjusting waist hole 204311, can precisely adjust the tension of the tensioning component 20433 on the limiting conveyor belt 2044. Loosening the locking bolt 20434 and pushing the sliding seat 20431 to slide up and down along the rotating arm 202 can drive the tensioning component 20433 to move synchronously through the connecting rod 20432. For silk multi-strand filaments of different diameters, the tension of the limiting conveyor belt 2044 can be flexibly adjusted. When the filament diameter is small, the conveyor belt is loosened to avoid excessive compression that could cause the filaments to break; when the filament diameter is large, the conveyor belt is tightened to ensure that the filaments do not slip or deviate during conveying.

[0028] As a further preferred embodiment, the upper end of the sliding seat 2051 is provided with an adjustment waist hole 20511, and the upper side of the front end of the rotating arm 202 is provided with a corresponding locking hole 2022. The locking hole 2022 is internally threaded with a locking bolt 2054, and the threaded part of the locking bolt 2054 is slidably adapted to the adjustment waist hole 20511.

[0029] As a further preferred embodiment, a guide 303 is provided between the pressure roller module 205 and the receiving module 302.

[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
