Description

Technical Field

[0001] This utility model relates to the field of silk spinning drawing frames, and specifically to a silk spinning drawing frame. Background Technology

[0002] In the silk spinning production process, the silk spinning drawing frame is the core upstream equipment. It takes multiple silk raw material slivers of uneven thickness and loose structure and forms a semi-finished sliver through the processes of drafting and merging. The current working process of the silk spinning drawing frame is as follows: multiple silk raw material slivers are first guided and shaped by the feed guide plate and then enter the main body of the drawing frame. The rollers in the main body and the rotatable and openable sizing plate work together to initially shape the raw material slivers. Then, the front ends of the processed raw material slivers are formed. After the heads of the raw material slivers are aligned and initially twisted, they enter the trumpet-shaped drawing mouth and are merged. Finally, they are pulled out by the discharge pressure rollers to complete the drawing process.

[0003] However, in actual production, due to the uneven thickness of the multi-strand silk slivers, or the misalignment of their distribution position between the rollers and the flat plate during feeding, as well as inconsistent tension, the multi-strand slivers are prone to stacking and clogging when entering the trumpet-shaped drawing mouth. Some raw material fibers become stuck in the narrow channel of the trumpet-shaped drawing mouth, forming a blockage. The conventional method requires stopping the machine, removing the trumpet-shaped drawing mouth from the fixed plate, and then manually pulling or using tools such as flat-head pliers to remove the blocked raw material. This is not only cumbersome but also time-consuming. Utility Model Content

[0004] This invention provides a silk spinning drawing frame to address the problems of existing technologies.

[0005] The objective of this utility model can be achieved through the following technical solution: A silk spinning drawing frame includes: a drawing frame main body, a feeding guide plate, and a winding assembly. The feeding guide plate is disposed at the input end of the drawing frame main body. The drawing frame main body includes a frame, rollers, a straightening plate, a fixed plate, a trumpet-shaped drawing mouth, and a discharge pressure roller. The rollers are rotatably disposed inside the frame. The straightening plate is rotatably disposed on the frame and located above the rollers. The fixed plate is fixed to the front side of the frame. The trumpet-shaped drawing mouth is snapped onto the fixed plate. The trumpet-shaped drawing mouth has a conical cavity inside. The discharge pressure roller is disposed on the frame and located below the trumpet-shaped drawing mouth. The winding assembly includes an upper fixed plate and a sliding rotating rod. The upper fixed plate is fixed to the frame and located above the trumpet-shaped drawing mouth. The sliding rotating rod is slidably disposed on the upper fixed plate. A winding rod is spaced at the lower end of the sliding rotating rod.

[0006] In a further improvement, the upper fixed plate is provided with a limiting seat, the sliding rotating rod is provided with a limiting hole, and a locking bolt is threadedly connected to the limiting seat, with one end of the locking bolt matched and set in the limiting hole.

[0007] As a further improvement, the top of the sliding lever is provided with a rotating handle.

[0008] In a further improvement, the width of several sets of winding rods is set to decrease sequentially from top to bottom.

[0009] As a further improvement, the rear end of the drawing frame is provided with a pressure roller located between the roller roller and the feed guide plate.

[0019] The following describes the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0020] Example 1

[0021] A silk spinning drawing frame includes: a drawing frame main body 1, a feed guide plate 2, and a winding assembly 3. The feed guide plate 2 is disposed at the input end of the drawing frame main body 1. The drawing frame main body 1 includes a frame 11, rollers 13, a straightening plate 14, a fixing plate 15, a bell-shaped drawing mouth 16, and an output pressure roller 17. The rollers 13 are rotatably disposed inside the frame 11. The straightening plate 14 is rotatably disposed on the frame 11 and located above the rollers 13. The fixing plate 15 is fixed to the front of the frame 11. On the side, the horn-shaped drawing mouth 16 is snapped onto the fixed plate 15. The horn-shaped drawing mouth 16 has a conical cavity 161 inside. The discharge pressure roller 17 is set on the frame 11 and located below the horn-shaped drawing mouth 16. The winding assembly 3 includes an upper fixed plate 31 and a sliding rotating rod 32. The upper fixed plate 31 is fixed on the frame 1 and located above the horn-shaped drawing mouth 16. The sliding rotating rod 32 is slidably set on the upper fixed plate 31. The lower end of the sliding rotating rod 32 is provided with winding rods 33 at intervals.

[0022] like Figures 1-3 As shown, the working principle of this utility model is as follows:

[0023] Multiple strands of silk raw material are placed at corresponding positions on the feed guide plate 2. The raw material strands enter the main body 1 of the drawing frame along the guiding structure of the feed guide plate. The raw material strands first pass through the pressure roller 12 between the roller roller 13 and the feed guide plate 2. The pressure roller 12 performs preliminary flattening and straightening of the raw material strands by rotating itself, preventing the raw material strands from becoming loose and curled up. The raw material strands that have undergone preliminary straightening enter between the roller roller 13 and the straightening plate 14. The roller roller 13 rotates continuously, providing forward stretching power for the raw material strands. The straightening plate 14 covers the roller roller. At the upper end of 13, the raw material strip is flattened by its own weight, eliminating fiber gaps inside the raw material strip and improving density uniformity. After the flattened multi-strand raw material strips have their ends formed, they simultaneously enter the trumpet-shaped sizing inlet 16 on the fixed plate 15. The conical cavity 161 inside the trumpet-shaped sizing inlet 16 has a structure that is wider at the top and narrower at the bottom, which can gradually gather and twist the multi-strand dispersed raw material strips into a single continuous semi-finished strip. The combined strip is pulled by the discharge pressure roller 17 below the trumpet-shaped sizing inlet 16 and stably output to the subsequent process to complete the sizing.

[0024] When material blockage occurs in the conical cavity 161, without disassembling the horn and strip opening 16, directly operate the winding assembly 3, push the sliding rod 32 to move it downward from the sliding channel of the upper fixed plate 31 until the winding rod 33 at the lower end of the sliding rod 32 is fully inserted into the conical cavity 161; rotate the sliding rod 32, causing the winding rod 33 to rotate synchronously in the conical cavity 161, and the winding rod 33 wraps the blocked material strip around its own body, realizing the grabbing and fixing of the blocked material; pull the sliding rod 32 upward, and the winding rod 33 carries the wrapped blocked material upward synchronously, disengaging from the conical cavity 161, completing the blockage clearing; after clearing, return the sliding rod 32 to the upper fixed plate 31, without affecting subsequent normal production.

[0025] It changes the traditional cumbersome method of disassembling the horn-shaped drawing frame and cleaning manually or with tools. When blocked, there is no need to stop the machine to disassemble parts. The blockage can be cleared by simply operating the sliding rotating rod and the winding rod. The cleaning time is shortened, which greatly improves the continuity of production and reduces the labor intensity of operators. The roll assembly is directly integrated into the frame, which does not require major modification to the core structure of the drawing frame. It can be adapted to the upgrade and transformation of most existing silk spinning drawing frames, reducing equipment replacement costs.

[0026] As a further preferred embodiment, the upper fixed plate 31 is provided with a limiting seat 34, and the sliding rotating rod 32 is provided with a limiting hole 321. A locking bolt 35 is threadedly connected to the limiting seat 34, and one end of the locking bolt 35 is matched and disposed in the limiting hole 321. During normal production, the sliding rotating rod 32 is moved up to the highest position, and the locking bolt 35 is screwed into the limiting hole 321 at the corresponding height. The sliding rotating rod 32 is fixed by the cooperation of the bolt and the hole, preventing it from moving down due to equipment vibration or accidental contact, and avoiding interference with the entry of raw material strips into the trumpet-shaped strip opening 16.

[0027] As a further preferred embodiment, the top of the sliding rod 32 is provided with a rotating handle 322. The rotating handle 322 has a circular or polygonal structure and is fixed to the top of the sliding rod 32, thereby increasing the contact area between the operator's hand and the rod.

[0028] As a further preferred embodiment, the width of the several sets of winding rods 33 is progressively reduced from top to bottom. The conical cavity 161 of the horn-shaped opening 16 has a gradually decreasing structure that is wider at the top and narrower at the bottom. The width of the winding rod 33 gradually decreases from the top to the bottom, and its width change trend matches the inclination angle of the inner wall of the conical cavity 161. When the winding rod 33 is inserted into the conical cavity 161, the rod body and the cavity wall always maintain a uniform gap. This prevents the upper end from being too narrow, which would prevent the thicker top material from being wound, and also prevents the lower end from being too wide, which would cause it to get stuck at the narrow bottom of the conical cavity 161.

[0029] As a further preferred embodiment, the rear end of the drawing frame 1 is provided with a pressure roller 12 located between the roller roller 13 and the feed guide plate 2. The pressure roller 12 rotates synchronously under the drive of the raw material strip, and uses its own gravity to initially flatten and straighten the raw material strip, eliminating the curled and fluffy state of the raw material strip caused by transportation or storage, so that the raw material strip enters between the subsequent roller roller 13 and the flat plate 14 in a more regular shape.

[0030] In a further preferred embodiment, a hydraulic push rod 112 is rotatably connected to the frame 11 via a rotating seat 111, and a rotating seat 113 is provided on the bottom left side of the flat plate 14. The upper end of the hydraulic push rod 112 is rotatably connected to the rotating seat 113. The hydraulic push rod 112 can be extended and retracted by hydraulic drive. When the push rod extends, it pushes the rotating seat 113 to move upward, causing the flat plate 14 to rotate upward around its rotation point with the frame. When the push rod shortens, it pulls the rotating seat 113 to move downward, causing the flat plate 14 to rotate downward, reducing the gap, stabilizing the hydraulic thrust, and providing uniform downward pressure to the flat plate.

[0031] In a further preferred embodiment, the feed guide plate 2 includes a base plate 21, a vertical plate 22, a guide plate 23, and a horizontal plate 24. The vertical plate is disposed above the base plate 21. The guide plate 23 and the horizontal plate 24 are vertically slidably disposed within the vertical plate 22. The horizontal plate 24 is fixed to the top of the guide plate 23 and passes through the vertical plate 22. The bottom of the guide plate 23 is provided with guide grooves 231 at intervals. Multiple raw material strips are respectively placed into the corresponding guide grooves 231, which can separate the raw material strips and prevent excessive stacking.

[0032] 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.
