Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a stain-resistant automatic yarn reeling machine guide drum. Background Technology

[0002] During the silk reeling process, the raw silk needs to pass through multiple guide drums. The silk strands pass back and forth through these guide drums, increasing the reeling tension during the silk forming process, thus affecting the tensile properties of the raw silk. Furthermore, the existing drum design has a flaw in its anti-fouling properties; after the drum cover and drum core are assembled as a single unit, the structural design cannot effectively prevent sericin contamination, thereby affecting the normal operation of the equipment.

[0003] Reducing the resistance of the drum core rotation during yarn guiding is key to lowering reeling tension. Previously, the drum core shaft was made of steel wire and integrated with the drum core (see patents: CN2185754Y, CN2579915Y). The drum core shaft was positioned by a drum support, which was fixed to a drum bracket. Because the drum bracket was made of bent stainless steel, the two sides of the bracket were not parallel, causing the drum support center to be off-line. This affected the flexible rotation of the drum core shaft within the drum support, and the drum core's left-right position relative to the drum bracket was inconsistent during installation, impacting practical use and severely affecting the quality of the raw yarn. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a contamination-resistant guide drum for an automatic silk reeling machine. This invention offers advantages such as flexible drum core rotation, prevention of inaccurate detection, and contamination resistance.

[0005] This utility model provides a stain-resistant automatic silk reeling machine guide drum, including a drum core and drum shells coaxially disposed on both sides of the drum core. The drum core and the two drum shells are coaxially connected by an axial fixing assembly. A rotating support assembly coaxial with the two drum shells is provided on the drum core, and the drum core is rotatably arranged on the axial fixing assembly through the rotating support assembly. A connecting part for axially positioning the rotating support assembly is provided on the drum shell. The connecting part is inserted into the drum core and abuts against the side wall of the rotating support assembly. A stain-resistant baffle is provided on the outside of the rolling gap between the connecting part and the drum core.

[0006] In one embodiment, the drum core includes guide wheel cover plates coaxially disposed on both sides of the rotating support assembly, and the guide wheel cover plates are fixedly connected to the rotating support assembly; the connecting parts on both sides of the drum core are inserted into the guide wheel cover plates and abut against the side walls of the rotating support assembly, and the rolling gap is provided between the connecting parts and the inner wall of the guide wheel cover plates.

[0007] In one embodiment, the guide wheel cover plate has a guide wheel coaxially arranged in the middle, the outer surface of the guide wheel cover plate in the radial direction is provided with an inclined guide surface, and the outer surface of the guide wheel in the radial direction is provided with a concave arc-shaped working surface. The inclined guide surface and the working surface of the guide wheel cooperate to form an outwardly expanding V-shaped guide channel.

[0008] In one embodiment, the guide wheel cover plate has cover plate protrusions on both sides.

[0009] In one embodiment, a reinforcing rib is provided between the outer surface of the connecting portion in the radial direction and the inner wall of the drum housing.

[0010] In one embodiment, multiple reinforcing ribs are provided and are arranged circumferentially between the outer surface of the connecting part and the inner wall of the drum cover.

[0011] In one embodiment, the axial fixing assembly includes a mandrel that extends through the drum core and the drum housing, with clamping members provided on both sides of the drum housing on the mandrel.

[0012] In one embodiment, the anti-fouling baffle is arranged in a ring shape at the connection point, and the maximum outer diameter of the anti-fouling baffle is greater than the maximum gap diameter of the rolling gap.

[0013] In one embodiment, the sidewall of the drum housing is configured as an integrally closed structure, with only an axial inner hole for the mandrel to pass through.

[0014] The beneficial effects of the anti-fouling automatic silk reeling machine guide drum provided in this embodiment of the invention are as follows:

[0015] The structural design of this utility model device not only improves the rotational flexibility of the drum core and avoids inaccurate detection, but also has the advantage of anti-pollution.

[0016] Firstly, this invention features a rotating connection component on the drum core, enabling flexible rotational connection between the drum core and the mandrel. Combined with precise positioning of the connection points and clamping components, this ensures good centering of the drum core, facilitating the straight-line movement of the yarn and effectively preventing inaccurate detection. Simultaneously, the drum core and housing are mounted on the mandrel using a two-sided clamping method. This structure not only facilitates installation but also ensures flexible rotation of the drum core, preventing obstruction of the guide wheel's rotation due to improper assembly. This achieves low-tension reeling, significantly improving the tensile properties of the raw silk, and is fully compatible with existing automatic reeling machines.

[0017] This utility model features a unique anti-fouling structural design: the connecting part not only achieves the axial positioning function of the drum core but also has an anti-fouling baffle to effectively prevent external impurities from entering the rolling gap; the drum cover adopts an overall closed structure, retaining only the necessary core shaft through holes to prevent water and contaminants from entering; the raised design of the guide wheel cover plate can prevent the wire from sliding in from the gap.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0027] like Figures 1 to 4 As shown, the anti-fouling automatic silk reeling machine guide drum includes a drum core 1 and drum shells 2 coaxially disposed on both sides of the drum core 1. The drum core 1 and the two drum shells 2 are coaxially connected by an axial fixing assembly 3. A rotating support assembly 14 coaxial with the two drum shells 2 is provided on the drum core 1. The drum core 1 is rotatably arranged on the axial fixing assembly 3 through the rotating support assembly 14. The rotating support assembly 14 adopts a bearing structure. A connecting part 21 for axially positioning the rotating support assembly 14 is provided on the drum shell 2. The connecting part 21 is inserted into the drum core 1 and abuts against the side wall of the rotating support assembly 14. An anti-fouling baffle 202 is provided on the outside of the rolling gap 4 between the connecting part 21 and the drum core 1.

[0028] The drum core 1 includes guide wheel cover plates 12 coaxially disposed on both sides of the rotating support assembly 14, and the guide wheel cover plates 12 are fixedly connected to the rotating support assembly 14; the connecting parts 21 on both sides of the drum core 1 are inserted into the guide wheel cover plates 12 and abut against the side wall of the rotating support assembly 14, and the rolling gap 4 is provided between the connecting parts 21 and the inner wall of the guide wheel cover plates 12.

[0029] The guide wheel cover plate 12 has a guide wheel 11 coaxially arranged in the middle. The outer surface of the guide wheel cover plate 12 in the radial direction is provided with an inclined guide surface 125. The outer surface of the guide wheel 11 in the radial direction is provided with a concave arc-shaped working surface 111. The concave arc shape of the working surface 111 facilitates the stable operation of the introduced wire on the working surface 111. The inclined guide surface 125 and the working surface 111 of the guide wheel 11 cooperate to form an outwardly expanding V-shaped guide channel, which facilitates the introduction of the wire.

[0030] In this embodiment, two guide wheel cover plates 12 are symmetrically arranged on both sides of the guide wheel 11 and the rotating support assembly 14. The guide wheel cover plates 12 are fixedly connected to the guide wheel 11 and the rotating support assembly 14 by screws 13 to form the drum core 1. The guide wheel cover plates 12 are provided with guide wheel cover plate flanges 122, which abut against the side of the bearing outer ring 142 to realize the axial positioning and coaxial holding function of the rotating support assembly 14. During operation, the guide wheel 11 and the guide wheel cover plates 12 rotate synchronously with the bearing outer ring 142.

[0031] The guide wheel 11, which acts as a guide, is integral with the outer ring 142 of the bearing. After being connected by screws 13, there is no gap between it and the guide wheel cover plate 12. The drum core 1 is positioned horizontally and horizontally with the inner ring 141 of the bearing by the mandrel 3 and the positioning end face 203 of the connecting part 21, with no gap. The drum core 1 is located at the center of the drum cover 2, which is convenient for installation, and the components have good uniformity and interchangeability, which is conducive to accurate yarn positioning. The drum core 1 and the mandrel 3 are connected by a bearing assembly, which allows for flexible rotation and low friction, which helps to reduce yarn tension and has a significant effect on improving the quality of raw silk.

[0032] The drum housing 2 is provided with an opening for the introduction of the wire. The size B of this opening is smaller than the opening size A of the V-shaped wire guide channel, which can effectively prevent the wire from entering the drum and causing malfunctions.

[0033] Both sides of the guide wheel cover plate 12 are provided with cover plate protrusions 123. The guide wheel cover plate protrusions 123 can block the wire from sliding into the gap between the drum shell 2 and the guide wheel cover plate 12, ensuring that the drum core 1 rotates flexibly.

[0034] A reinforcing rib 201 is provided between the outer surface of the connecting part 21 in the radial direction and the inner wall of the drum shell 2; multiple reinforcing ribs 201 are provided and are arranged circumferentially between the outer surface of the connecting part 21 and the inner wall of the drum shell 2, and the setting of the reinforcing ribs 201 enhances the rigidity of the connecting part 21.

[0035] The axial fixing assembly 3 includes a spindle 31 that passes through the drum core 1 and the drum cover 2, and clamping elements are provided on both sides of the drum cover 2 on the spindle 31.

[0036] In this embodiment, the mandrel 3 has a mandrel head 301 at one end that is a cylindrical plug with a size larger than the axial inner hole 204. The clamping elements on both sides of the drum housing 2 on the mandrel 3 can be the mandrel head 301 and a nut 33. The mandrel head 301 at one end of the mandrel has a size larger than the axial inner hole 204 of the drum housing 2, serving as a positioning and blocking function. The mandrel tail 302 at the other end of the mandrel 3 extends outside the drum housing 2 and has external threads, which can be used for fastening the nut 33 and can also be used for installation at any desired location on the machine. Gaskets 32 are provided between the mandrel head 301 and the drum housing 2, and between the nut 33 and the drum housing 2.

[0037] The anti-fouling baffle 202 is arranged in a ring on the connecting part 21. The maximum outer diameter of the anti-fouling baffle 202 is greater than the maximum gap diameter of the rolling gap 4, which serves to block impurities and threads.

[0038] The side wall of the drum housing 2 is set as an integral closed structure, with only an axial inner hole 204 for the spindle 31 to pass through. This can effectively prevent water and debris from entering the drum from the side wall of the drum housing 2, thus affecting the operation and achieving a dirt-proof effect.

[0039] In this embodiment, the bearing structure is made of stainless steel or ceramic, which is rust-free, corrosion-resistant, and washable. The guide wheel 11 has a smooth surface and is made of alumina or zirconium oxide, which is hard, wear-resistant, rust-free, corrosion-resistant, and washable. The drum shell 2 and the guide wheel cover 12 are made of engineering plastic, which is high-strength, non-deformable, and washable. All of the above meet the requirements of high humidity during reeling and drum cleaning. The mandrel 3 is made of stainless steel, with a diameter of 4-6mm to match the inner hole of the bearing inner ring 141, which satisfies both good rigidity and stable fixation, and also allows for a smaller bearing size, reducing the weight of the drum core 1 and thus allowing for lower wire tension.
