Description

Technical Field

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

[0002] In the silk spinning production process, the core function of the silk spinning drawing frame is to draft and combine multiple silk raw material slivers of uneven thickness to form a semi-finished sliver with higher uniformity and more stable structure, laying the foundation for subsequent spinning processes. The feeding mechanism, as a pre-component of the silk spinning drawing frame, delivers the raw material slivers released from several sets of silk raw material sliver cans to the drafting mechanism of the drawing frame in a stable and regular state.

[0003] Due to differences in raw material types, such as mulberry silk and tussah silk, and processing specifications, the outer diameter and release width of silk sliver rolls vary significantly. However, the limiting components of conventional feeding mechanisms, such as baffles and guide plates, are mostly fixed structures and cannot adjust the limiting range according to the size of the roll. This causes the raw material rolls of different specifications to shift in position at the initial feeding stage. Moreover, during the conveying process, the raw material rolls are prone to vertical movement due to their own tension fluctuations and equipment vibrations. Utility Model Content

[0004] This utility model provides a feeding mechanism for a silk spinning drawing frame to solve the problems of the prior art.

[0005] The objective of this utility model can be achieved through the following technical solution: A feeding mechanism for a silk spinning drawing frame includes: a worktable, a guide rail, several sets of limiting components one and several sets of limiting components two. The guide rail is symmetrically fixed to the lower end of the worktable. The limiting component one includes a limiting plate one and a limiting plate two, which are slidably disposed on the guide rail. The limiting component two includes a guide roller, a rotating shaft, a threaded part, and a limiting sleeve. The guide roller is rotatably disposed on the worktable via the rotating shaft. The threaded part is fixed to the upper end of the guide roller. The limiting sleeve includes a threaded sleeve part, a sliding sleeve, and a pressure plate fixed downward in sequence. The threaded sleeve part is threaded onto the threaded part. The sliding sleeve is sleeved on the guide roller. The pressure plate is located at the lower end of the sliding sleeve. The discharge end of the worktable is symmetrically provided with discharge clamping rollers.

[0006] In a further improvement, the first and second limiting components are arranged in five rows symmetrically on the worktable.

[0007] In a further improvement, the guide rail is provided with a limiting groove in the middle of both sides. The limiting plate one and the limiting plate two each include a clamping plate, a fixing seat and a fixing bolt. The fixing seat is slidably disposed on the guide rail and is provided with a protrusion matching the limiting groove. The bottom of the clamping plate is threaded to the outside of the fixing seat through a threaded rod. The fixing bolt is threaded to the inside of the fixing seat. The fixing seat is clamped and fixed to the guide rail by the fixing bolt.

[0008] As a further improvement, each set of limiting components two has an antistatic roller at its outer rear end.

[0009] In a further improvement, the cross-section of the clamping plate is set in an arc shape.

[0010] Compared with the prior art, the beneficial effects of this utility model on the feeding mechanism of a silk spinning drawing frame are as follows:

[0011] By adjusting the sliding of the limiting component one on the guide rail, it can be adapted to silk raw material rolls of different sizes and release widths without replacing the entire limiting structure. The pressure plate in the limiting component two can also be adjusted in height according to the size of the raw material strip to limit vertical movement. The combination of the horizontal limiting of the limiting component one and the vertical limiting of the limiting component two effectively solves the problem of chaotic raw material feeding path.

[0018] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0019] Example 1

[0020] A feeding mechanism for a silk spinning drawing frame includes: a worktable 1, a guide rail 2, several sets of limiting components 3 and several sets of limiting components 4. The guide rail 2 is symmetrically fixed to the lower end of the worktable 1. Each limiting component 3 includes a limiting plate 31 and a limiting plate 32, which are slidably disposed on the guide rail 2. Each limiting component 4 includes a guide roller 41, a rotating shaft 42, a threaded portion 43, and a limiting sleeve 44. Roller 41 is rotatably mounted on workbench 1 via shaft 42. The threaded part 43 is fixed to the upper end of guide roller 41. The limiting sleeve 44 includes a threaded sleeve part 441, a sliding sleeve 442 and a pressure plate 443 fixed downward in sequence. The threaded sleeve part 441 is threaded onto the threaded part 43. The sliding sleeve 442 is sleeved on guide roller 41. The pressure plate 443 is located at the lower end of sliding sleeve 442. Discharge clamping rollers 11 are symmetrically provided at the discharge end of workbench 1.

[0021] like Figures 1-4 As shown, the working principle of this utility model is as follows: After the silk raw material strip is released from the strip roll drum, it first enters the feeding end of the worktable 1, and then passes through the double limiting components 3 and 4 in sequence. Finally, it is neatly conveyed to the drafting mechanism of the silk spinning drawing frame through the discharge clamping roller 11. The drafting mechanism (not shown) provides power to pull the silk raw material strip forward.

[0022] The guide rail 2 is symmetrically fixed to the lower end of the worktable 1, providing a sliding track for the limiting component 3; the limiting component 3 consists of a limiting plate 31 and a limiting plate 32, both of which are slidably mounted on the guide rail 2.

[0023] When feeding strip rolls with different outer diameters and release widths, the limiting plate 31 and the limiting plate 32 can be pushed to slide along the guide rail 2 to adjust the horizontal distance between them. For strip rolls with larger outer diameters and wider release widths, the distance between the limiting plates 31 and 32 is increased; for strip rolls with smaller outer diameters and narrower release widths, the distance is decreased, thereby achieving initial horizontal limiting of the raw material strips and preventing the raw material strips from shifting left and right in the initial stage of conveying.

[0024] The guide roller 41 of the limiting component 2 4 is rotatably mounted on the worktable 1 via the rotating shaft 42. When the raw material strip is conveyed, it will contact the surface of the guide roller 41. The guide roller rotates synchronously with the movement of the raw material strip, converting sliding friction into rolling friction and reducing the wear of the raw material strip.

[0025] The threaded part 43 fixed at the upper end of the guide roller 41 forms a threaded engagement with the threaded sleeve part 441 of the limiting sleeve 44, and the sliding sleeve 442 is sleeved on the outside of the guide roller 41. By rotating the limiting sleeve 44, the threaded sleeve part 441 will move up and down along the threaded part 43, driving the lower pressure plate 443 to rise and fall synchronously: when the raw material strip is thicker, the limiting sleeve is rotated upward to raise the pressure plate and leave enough space; when the raw material strip is thinner, the limiting sleeve is rotated downward to lower the pressure plate until the pressure plate gently presses against the surface of the raw material strip, thereby achieving rigid vertical limiting of the raw material strip and preventing it from moving up and down; since the number of raw material strips entering the pressure plate 44 of the guide roller 41 closer to the discharge clamping roller 11 is more, the height of the pressure plate 443 of the guide roller 41 closer to the discharge clamping roller 11 is adjusted higher to ensure that multiple sets of raw material strips are limited.

[0026] As a further preferred embodiment, the limiting component 3 and the limiting component 4 are provided with five rows symmetrically arranged on the worktable 1, and ten independent raw material strip conveying channels to meet the needs of the drawing machine for synchronous feeding of multiple raw material strips.

[0027] As a further preferred embodiment, the guide rail 2 has a limiting groove 21 in the middle of both sides. Both the limiting plate 1 31 and the limiting plate 2 32 include a clamping plate 33, a fixing seat 34, and a fixing bolt 35. The fixing seat 34 is slidably disposed on the guide rail 2 and has a protrusion 36 matching the limiting groove 21. The bottom of the clamping plate 33 is threaded to the outside of the fixing seat 34 via a threaded rod 331, and the fixing bolt 35 is threaded to the inside of the fixing seat 34, clamping and fixing the fixing seat 34 to the guide rail 2. The cooperation between the limiting groove and the protrusion prevents the fixing seat from sliding off-center, significantly reducing the position adjustment error of the limiting plate and ensuring the accuracy of horizontal limiting. The fixing bolt is threaded to the inside of the fixing seat; when tightened, the inner wall of the fixing seat tightly fits the surface of the guide rail, achieving rigid fixing of the fixing seat through friction. The clamping plate is connected to the outside of the fixing seat via a threaded rod for easy installation.

[0028] As a further preferred embodiment, each set of limiting components 4 is provided with an antistatic roller 5 at its outer rear end. Silk raw materials, such as silkworm silk and spun silk, are fibers with strong insulating properties. During the conveying process, they will repeatedly rub against components such as the guide roller 41 and pressure plate 443, generating static electricity. The antistatic roller 5 effectively neutralizes the static electricity on the surface of the raw material strip. The antistatic roller 5 is existing technology and will not be described further.

[0029] As a further preferred embodiment, the clamping plate 33 has an arc-shaped cross-section.

[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.
