Description

Technical fields:

[0001] This utility model relates to the technical field of textile machinery, and more specifically to a positioning bracket for the feeding hopper of a textile drawing frame. Background technology:

[0002] A drawing frame is a type of textile equipment mainly used to improve the uniformity, mixing properties, and structure of fiber slivers, providing high-quality raw materials for subsequent spinning processes. The existing drawing frame structure is designed around its core functions (drawing, drafting, mixing, and sliver forming). Different models differ in details, but the overall structure can be divided into the following components: feeding section, traction section, drawing section, transmission section, and cleaning section. The feeding section mainly consists of an elevated guide frame composed of multiple guide rollers and pressure rollers. The elevated guide frame has many sliver cans arranged in an array. The sliver cans contain slivers, which are fed in through the guide frame and then drawn together. To facilitate handling and movement, the sliver cans are generally equipped with rollers at the bottom. The sliver cans can be easily pushed using the rollers. The presence of rollers has both advantages and disadvantages. In terms of positioning, the sliver cans are prone to displacement due to external interference, especially the sliver cans located below the drawing frame. When the sliver cans are displaced, the slivers output from multiple sliver cans may become entangled. Therefore, it is necessary to design a positioning bracket below the guide frame of the drawing frame to position the sliver cans. Utility Model Content:

[0003] The purpose of this utility model is to address the shortcomings of existing technology by providing a positioning bracket for the feed sliver of a textile drawing frame. It is set below the guide frame of the drawing frame and can effectively constrain the sliver sliver under the guide frame, preventing the sliver from tangling due to movement of the sliver sliver.

[0021] Example: See Figures 1 to 4 As shown, a positioning bracket for a feeding hopper of a textile drawing frame includes a transverse strip-shaped central mounting plate 1. The central mounting plate 1 has several transversely distributed mounting slots 11 formed on it. Several transversely distributed positioning brackets 2 are respectively provided on the front and rear sides of the central mounting plate 1. The positioning bracket 2 includes a horizontal E-shaped inner positioning frame 21. Longitudinal angle irons 22 are inserted into both sides of the inner positioning frame 21. The inner ends of the angle irons 22 are fixed to the central mounting plate 1.

[0022] The upper surface of the angle iron 22 has a longitudinal limiting groove 221. A vertical limiting bolt 25 is inserted into the inner end of the limiting groove 221. The lower end of the limiting bolt 25 passes through the angle iron 22 and is screwed to a transverse limiting stop 24. Several connecting blocks 23 are fixedly connected between the limiting stop 24 and the inner positioning frame 21. Two sets of hinge lugs 211 are formed on the outer frame of the inner positioning frame 21. The hinge lugs 211 are distributed on both sides of the inner positioning frame 21 and located on the outer side of the angle iron 22. A horizontal T-shaped locking bracket 26 is provided above the outer end of the angle iron 22. A vertical limiting pin 27 is fixedly connected to the inner end of the locking bracket 26. The lower end of the limiting pin 27 is inserted into the outer end of the limiting groove 221. A vertical support lug 2 is formed on the outer end of the locking bracket 26. 61. The lower end of the support ear 261 is inserted into the hinge ear seat 211 and hinged to the hinge ear seat 211 by the upper pin 220; the side end of the locking bracket 26 is inserted into the vertical channel steel-shaped handrail side rod 28, the upper ends of the handrail side rod 28 are fixedly connected to the horizontal handrail 210, the lower part of the handrail side rod 28 is formed with a vertical guide groove 281, a T-shaped guide pin 29 is inserted into the guide groove 281, the end of the guide pin 29 is inserted and fixed in the side end of the locking bracket 26, the bottom of the handrail side rod 28 is formed with a limiting socket 282, the outer frame of the inner positioning frame 21 is inserted into the limiting socket 282 of the handrail side rod 28; the hinge ear seat 211 is composed of two sets of longitudinal ear plates, and a slot is provided between the ear plates.

[0023] The angle iron 22 is fixed to the front and rear side walls of the center mounting plate 1, and the lower end face of the angle iron 22 is flush with the lower end face of the center mounting plate 1; thus, the angle iron 22 and the center mounting plate 1 can be placed flat on the ground below the guide frame of the drawing frame.

[0024] The inner end of the angle iron 22 is formed with a horizontal support plate 222. The support plate 222 is fixed to the upper surface of the central mounting plate 1. It can be fixed by welding. The support plate 222 strengthens the connection between the angle iron 22 and the central mounting plate 1.

[0025] The lower end face of the inner positioning frame 21, the lower end face of the limiting stop bar 24, and the lower end face of the connecting block 23 are flush. The lower end face of the inner positioning frame 21 is located above the lower end face of the angle iron 22, so the inner positioning frame 21 is detached from the ground and there is no friction between it and the ground, which facilitates the pulling of the inner positioning frame 21. At the same time, the height of the inner positioning frame 21 is increased, which makes it easier for the inner side wall of the inner positioning frame 21 to abut against the outer wall of the bottom of the material barrel.

[0026] A guide wheel 230 is inserted into the hinged lug 211 on the lower side of the support lug 261. A horizontal lower pin 240 is inserted into the guide wheel 230. Both ends of the lower pin 240 are respectively inserted and fixed on the hinged lug 211. The bottom end of the guide wheel 230 is flush with the lower end face of the angle iron 22. The guide wheel 230 can provide support for the outer frame of the inner positioning frame 21.

[0027] The diameter of the guide pin 29 is equal to the width of the guide groove 281 on the handrail side rod 28, the width of the side end of the locking bracket 26 is equal to the width of the inner channel of the handrail side rod 28, and the width of the limiting socket 282 at the bottom of the handrail side rod 28 is equal to the width of the outer frame of the inner positioning frame 21.

[0028] The depth of the upper limit insertion port 282 of the handrail side rod 28 is less than the distance from the guide pin 29 to the lower end of the guide groove 281. Thus, lifting the handrail side rod 28 can disengage it from the inner positioning frame 21. At the same time, based on the side end of the locking bracket 26 abutting against the inner groove side wall of the handrail side rod 28, flipping the handrail side rod 28 can drive the locking bracket 26 to flip.

[0029] The positioning brackets 2 are linearly and evenly distributed on the central mounting plate 1, and the angle irons 22 on adjacent positioning brackets 2 abut against each other.

[0030] The length of the connecting block 23 is greater than the distance from the outer end of the angle iron 22 to the outer end of the limiting groove 221; therefore, the inner positioning frame 21 is pulled out completely from the angle iron 22.

[0031] Working principle: This structure is a positioning bracket for the feed sliver of a textile drawing frame. The positioning bracket includes a central mounting plate 1 for fixing to the ground. The mounting slots 11 of the central mounting plate 1 can be fixed to the ground under the guide frame by expansion bolts. The positioning bracket 2 set on the central mounting plate 1 can constrain the cotton sliver sliver to be positioned on the ground and prevent it from shifting. The position of the cotton sliver sliver is in the two slots of the inner positioning frame 21. The inner positioning frame 21 cooperates with the angle iron 22 to constrain its movement.

[0032] When setting the tampons, you can hold the handrail 210 and pull the handrail side bar 28 to drive the handrail side bar 28 away from the inner positioning frame 21. Then drive the handrail side bar 28 to rotate outward, driving the locking bracket 26 to rotate, so that the limiting pin 27 can be released from the angle iron 22. Then you can pull the inner positioning frame 21 out of the angle iron 22, push the two tampons into the frame groove of the inner positioning frame 21, and then push the inner positioning frame 21 between the angle irons 22. Finally, the limiting pin 27 is inserted into the limiting groove 221 of the angle iron 22, and the handrail side bar 28 is sleeved on the inner positioning frame 21. The handrail side bar 28 sleeved on the inner positioning frame 21 can realize the rotation of the locking bracket 26. If the locking bracket 26 cannot rotate, the limiting pin 27 cannot be released from the angle iron 22, thus realizing the locking and positioning of the inner positioning frame 21.

[0033] When using a positioning bracket to replace tampons, adjacent tampons will not move due to the constraint of the positioning bracket.

[0034] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
