Description

Technical Field

[0001] This utility model belongs to the field of composite machinery and shaping machinery technology, specifically relating to a fabric spreading machine roller structure that is easy to maintain. Background Technology

[0002] In the production processes of lamination and shaping, elastic materials usually need to be stretched to a certain width to meet the requirements of lamination and shaping.

[0003] Patent application number 202411890406.1 discloses a fabric spreading machine. A first guide cylinder and a second guide cylinder are located inside a multi-grooved circular tube. The position of the first guide cylinder is adjusted in real time according to a sensing system. The first guide cylinder guides the guide wheel of the nail plate, adjusting the position of the nail plate so that the nail plate can fix the fabric boundary at the feed inlet of the fabric spreading machine. During the rotation of the multi-grooved circular tube, the nail plate guide wheel is pushed onto the second guide cylinder, which guides the guide wheel on the nail plate, expanding the fabric to the specified width. However, this design suffers from complex structure, high cost, and difficulty in maintenance. Utility Model Content

[0004] Therefore, in view of the problems of complex structure, high cost and difficulty in maintenance in the existing technology, this utility model provides a fabric spreading machine roller structure that is easy to maintain. It aims to reduce structural complexity and cost while keeping the function unchanged, and provide a structure that is easy to maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient fabric spreading machine roller structure, comprising a left rotating sleeve, a right rotating sleeve, a middle rotating sleeve, and profile spokes. Multiple profile spokes are evenly installed along the circumference of the left rotating sleeve, right rotating sleeve, and middle rotating sleeve. The profile spokes connect the left rotating sleeve, right rotating sleeve, and middle rotating sleeve into a rotatable whole. The cross-section of each profile spoke is I-shaped, including an outer wing plate, an inner wing plate, and a web plate. A space is formed between the outer wing plate, inner wing plate, and web plate to accommodate the sliding of the needle plate carriage roller. The distance between the edges of the outer wing plates of adjacent profile spokes is constant, forming a sliding limit on the upper end of the needle plate carriage. The distance between the inner wing plates of adjacent profile spokes is constant, forming a sliding limit on the lower end of the needle plate carriage.

[0006] Furthermore, the outer contour of the outer wing plate is an arc-shaped surface.

[0007] Furthermore, the radius of curvature of the arcuate surface is consistent with the distance from the outer contour of the outer wing plate to the rotation center of the roller structure.

[0008] Furthermore, a profile reinforcing outer hoop is installed on the outer ring at both ends of the profile spoke, and the reinforcing outer hoop tightens both ends of the profile spoke onto the left-hand swivel and the right-hand swivel respectively.

[0009] Furthermore, at least one of the left-hand rotating sleeve and the right-hand rotating sleeve is equipped with a drive gear, and the drive gear transmits power to rotate the sleeve.

[0010] Furthermore, the number of spokes in the profile is 10-14.

[0011] Furthermore, the number of spokes in the profile is 12.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model significantly improves the convenience of inspection and maintenance. It innovatively uses profile spokes connecting the left, right, and central rotating sleeves to form a rotating frame, replacing the traditional integral multi-groove round tube. During maintenance, only a few bolts on the profile spokes need to be removed to create a sufficiently wide opening in the frame, directly exposing the internal parts for maintenance. Compared to the method of completely disassembling the bulky round tube, this design greatly simplifies the maintenance process, reduces downtime and labor costs, and makes equipment maintenance more efficient and flexible.

[0014] 2. The cross-section of the profile spokes is I-shaped, including an outer wing plate, an inner wing plate, and a web plate. The outer wing plate, inner wing plate, and web plate form a space to accommodate the sliding of the needle plate carriage roller. The distance between the edges of the outer wing plates of adjacent profile spokes is constant, forming a sliding limit on the upper end of the needle plate carriage. The distance between the inner wing plates of adjacent profile spokes is constant, forming a sliding limit on the lower end of the needle plate carriage. Firstly, the I-shaped structure has high bending resistance, and it forms limits on the upper end, lower end, and roller of the needle plate carriage respectively, ensuring that the needle plate carriage can move stably and smoothly between the profile spokes.

[0015] 3. The structure of this utility model is relatively simple, easy to install, and has a low cost. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] like Figure 1-2 As shown, this solution is applied to a cylindrical fabric spreading machine, which includes a fixed component, a rotating component, a needle plate component, and a amplitude adjustment mechanism. The roller structure described in this solution is the rotating component. The two ends of the roller structure are rotatably connected to the fixed component through bearings and are driven to rotate by external force. The needle plate carriage 7 set on the rolling structure moves left and right as it rotates under the guidance of the amplitude adjustment mechanism, thereby achieving fabric stretching.

[0024] Specifically, such as Figure 3-5 As shown, the present solution describes a convenient maintenance roller structure for a fabric spreading machine, comprising a left rotating sleeve 1, a right rotating sleeve 2, a middle rotating sleeve 3, and profile spokes 4. Multiple profile spokes 4 are evenly installed along the circumference of the left rotating sleeve 1, right rotating sleeve 2, and middle rotating sleeve 3. The profile spokes 4 connect the left rotating sleeve 1, right rotating sleeve 2, and middle rotating sleeve 3 into a rotatable whole. The cross-section of each profile spoke 4 is I-shaped, including an outer wing plate 401, an inner wing plate 402, and a web plate 403. A space is formed between the outer wing plate 401, inner wing plate 402, and web plate 403 to accommodate the sliding of the needle plate carriage 7 roller. The edge spacing of the outer wing plates 401 of adjacent profile spokes 4 is constant, forming a sliding limit on the upper end of the needle plate carriage 7. The spacing of the inner wing plates 402 of adjacent profile spokes 4 is constant, forming a sliding limit on the lower end of the needle plate carriage 7. In this design, the profile spokes 4 are provided with through holes, and the left rotating sleeve 1, right rotating sleeve 2, and intermediate rotating sleeve 3 are provided with threaded holes. Two bolts are provided at each connection point, connecting the profile spokes 4, left rotating sleeve 1, right rotating sleeve 2, and intermediate rotating sleeve 3 into a fixed whole. The intermediate rotating sleeve 3 provides rigidity and stability in the middle of the profile spokes 4, preventing deformation. The profile spokes 4 have an I-shaped cross-section. Firstly, the I-shaped structure has high bending resistance, and secondly, it provides limits on the upper and lower ends of the needle plate carriage 7 and the rollers, ensuring that the needle plate carriage 7 can move stably and smoothly between the profile spokes 4. This design does not use the multi-groove round tube in the comparative technology, but instead uses profile spokes 4. During maintenance, only two or three bolts on the profile spokes 4 need to be removed to create an opening of several centimeters wide in the rotating assembly, allowing direct inspection of the internal parts. Compared to removing the entire multi-groove round tube for maintenance, this design is much easier to maintain.

[0025] In practical applications, the outer contour of the outer wing plate 401 is an arc-shaped surface. The radius of curvature of the arc-shaped surface is consistent with the distance from the outer contour of the outer wing plate 401 to the rotation center of the roller structure. The outer contours of all the profile spokes 4 form a cylindrical surface, which can provide better support for the elastic silicone strip between the left and right needle plate carriages 7.

[0026] In practical applications, profile reinforcing hoops 6 are installed on the outer rings at both ends of the profile spoke 4. The reinforcing hoops tighten both ends of the profile spoke 4 onto the left swivel sleeve 1 and the right swivel sleeve 2, respectively. This effectively prevents the profile spoke 4 from loosening, slipping, or rotating within the mounting holes of the swivel sleeves, ensuring reliable torque transmission and structural integrity; and enhancing the rigidity and fatigue resistance of the connection parts.

[0027] In practical applications, at least one of the left-turning sleeve 1 and the right-turning sleeve 2 is equipped with a drive gear 5, which transmits power to rotate the sleeve. The drive gear 5 inputs power to drive the left-turning sleeve 1 and the right-turning sleeve 2 to rotate. The rotational motion is transmitted synchronously through the evenly distributed profile spokes 4, so that the left-turning sleeve 1, the right-turning sleeve 2, and the middle turning sleeve 3 rotate as a whole around their axis.

[0028] In practical applications, the number of profile spokes 4 is 10-14. In this solution, the number of profile spokes 4 is 12. The number of profile spokes 4 determines the number of needle plate carriages 7. The more needle plate carriages 7 there are, the smoother the tension adjustment will be. However, under the same diameter, it means that the width of the carriage will be smaller, and the width of the outer wing plate 401 and inner wing plate 402 of the profile spokes 4 will also be smaller. The strength of a single profile spoke 4 will decrease, the processing cost will increase, and the installation will be more complicated. Considering multiple aspects, this solution has 12 profile spokes 4, which is convenient for processing and installation, and also ensures that there are enough needle plate carriages 7 to provide smooth tension.

[0029] In summary, the fabric spreading machine roller structure described in this utility model has the advantages of simple structure, low cost, and convenient maintenance.
