Technical Field

[0001] This utility model relates to the field of fabric spreading machine technology, specifically an improved fabric spreading device. Background Technology

[0002] Fabric spreading machines are an important piece of equipment in the garment manufacturing industry, playing a significant role in increasing garment production and improving worker efficiency. The spreading effect of the fabric spreading device within the machine determines the final result of the fabric spreading process.

[0003] To improve the spreading effect, the applicant applied for a spreading device with good uniformity on March 6, 2018 (application number CN201820316295.7). However, the above-mentioned existing spreading device requires several slide rails to be fixedly set on the drive roller in the circumferential direction, and then the spreading sheet is slidably assembled onto the slide rails. The above structural design not only makes the entire processing and assembly process more complicated, time-consuming and labor-intensive, but also makes it easy for the spreading sheet to get stuck due to processing errors. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an improved fabric spreading device, which solves the problem that the structural design between the spreading sheet and the transmission roller in existing spreading devices is complex in terms of processing and assembly, time-consuming and labor-intensive, and prone to jamming of the spreading sheet due to processing errors.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved spreading device includes a drive roller body and a plurality of spreading components spaced apart on the outer surface of the drive roller body; the outer surface of the drive roller body has an assembly groove formed along the length direction at the position corresponding to each spreading component, and the two side walls of each assembly groove have assembly grooves formed along the length direction; each spreading component includes at least one fixed spreading sheet, a plurality of movable spreading sheets and a plurality of mutually repelling units, the fixed spreading sheet is installed in the middle of the assembly groove, and each movable spreading sheet has a first sliding protrusion formed on both sides and is slidably assembled with the assembly groove, and mutually repelling units are provided between the fixed spreading sheet and the movable spreading sheet and between two adjacent movable spreading sheets.

[0007] Furthermore, the transmission roller body is manufactured using a single-piece molding process.

[0008] Furthermore, the transmission roller body is a one-piece molded aluminum profile.

[0009] Furthermore, both the movable and fixed display panels described in each piece are manufactured using a single-piece molding process.

[0010] Furthermore, both the movable and fixed display panels described in each piece are integrally molded plastic sheets.

[0011] Furthermore, both sides of the fixed spreading sheet are provided with second sliding protrusions that are slidably assembled with the assembly groove.

[0012] Furthermore, the middle part of the fixed spreading sheet is provided with at least one locking through hole for locking and fixing together with the bottom wall of the assembly groove.

[0013] Furthermore, a gap is left between the lower surface of each movable and fixed fabric piece and the bottom wall of the assembly groove.

[0014] Furthermore, each of the movable and fixed fabric pieces has an extension on both sides of its top surface that extends above the outer surface of the drive roller body.

[0015] Furthermore, the top surfaces of each movable and fixed display sheet have extended protrusions extending upwards at both sides.

[0016] By adopting the above-mentioned technical solution of this utility model, at least the following beneficial effects are achieved: Assembly grooves are integrally formed on both sides of each assembly groove of the transmission roller body, and first sliding protrusions are integrally formed on both sides of each movable fabric piece. The assembly grooves and first sliding protrusions are used to directly assemble each movable fabric piece with the transmission roller body. This structural design not only simplifies the entire processing and assembly process, making it more time-saving and labor-saving, and lowering costs, but also, because the movable fabric pieces are made of integrally formed plastic sheets, they are less prone to jamming during use, effectively reducing the frequency of downtime for maintenance and also lowering manufacturing costs.

[0023] Improved spreading device 100;

[0024] The transmission roller body 1 has an assembly groove 11 and an assembly slide 12.

[0025] The fabric spreading assembly 2 includes a fixed fabric spreading piece 21, a second sliding protrusion 211, a locking through hole 212, a movable fabric spreading piece 22, a first sliding protrusion 221, an extension 23, and an extension protrusion 24. Detailed Implementation

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see the appendix Figures 1 to 5 As shown, this utility model provides an improved spreading device 100, which includes a transmission roller body 1 and a plurality of spreading components 2 spaced apart on the outer surface of the transmission roller body 1. The transmission roller body 1 drives each spreading component 2 to rotate, and each spreading component 2 is used to perform the spreading function. An assembly groove 11 is formed along the length direction at the position corresponding to each spreading component 2 on the outer surface of the transmission roller body 1, and an assembly groove 12 is formed on both side walls of each assembly groove 11 along the length direction. In specific implementation of this utility model, in order to achieve uniform spreading, a plurality of assembly grooves 11 are equally spaced around the circumference on the outer surface of the transmission roller body 1, and a spreading component 2 is assembled in each assembly groove 11.

[0028] Each spreading assembly 2 includes at least one fixed spreading sheet 21, several movable spreading sheets 22, and several mutually repelling units (not shown). The fixed spreading sheet 21 is installed in the middle of the assembly slide 12. Each movable spreading sheet 22 has a first sliding protrusion 221 formed on both sides and is slidably assembled with the assembly slide 12, so that each movable spreading sheet 22 can move along the assembly slide 12 to achieve spreading. Mutually repelling units are provided between the fixed spreading sheet 21 and the movable spreading sheet 22, as well as between two adjacent movable spreading sheets 22. It should be noted that the core difference between the improved spreading device 100 of this utility model and the existing spreading device is that the assembly slide 12 is directly formed on both sides of each assembly groove 11 of the transmission roller body 1, and the first sliding protrusion 221 is directly formed on both sides of each movable spreading sheet 22. The assembly slide 12 and the first sliding protrusion 221 are used to directly assemble each movable spreading sheet 22 with the transmission roller body 1. The mutual repulsion units, the limiting structures at both ends of the transmission roller body 1, and the connection structure between the movable spreading pieces 22 located at both ends of the transmission roller body 1 and the transmission roller body 1 are all the same as those in the prior art. For details, please refer to the detailed description in CN201820316295.7. Detailed descriptions will not be provided here.

[0029] In some embodiments of this utility model, the transmission roller body 1 is manufactured by integral molding.

[0030] In one specific embodiment of this utility model, the transmission roller body 1 is an integrally formed aluminum profile. Of course, the above is only one specific embodiment of this utility model, but it is not limited to this; in specific implementations, transmission roller bodies of other materials can be used according to actual needs.

[0031] In some embodiments of this utility model, the movable display sheet 22 and the fixed display sheet 21 are all manufactured as a single piece.

[0032] In one specific embodiment of this utility model, the movable display sheet 22 and the fixed display sheet 21 are both integrally molded plastic sheets. Of course, the above is only one specific embodiment of this utility model, but it is not limited to this. In specific implementations, movable and fixed display sheets made of other materials can be used according to actual needs.

[0033] By adopting the above-mentioned technical solution of this utility model, at least the following beneficial effects are achieved: Assembly grooves 12 are integrally formed on both sides of the sidewalls of each assembly groove 11 of the transmission roller body 1, and first sliding protrusions 221 are integrally formed on both sides of each movable spreading sheet 22. The assembly grooves 12 and the first sliding protrusions 221 are used to directly assemble each movable spreading sheet 22 with the transmission roller body 1. This structural design simplifies the entire processing and assembly process (eliminating the need for additional processing of guide rails and other structures, and saving assembly steps), making the entire processing and assembly process more time-saving and labor-saving, and reducing costs. Furthermore, since the movable spreading sheet 22 is made of integrally formed plastic, it is less prone to jamming during use, effectively reducing the frequency of downtime for maintenance and lowering manufacturing costs.

[0034] In some embodiments of this utility model, the fixed spreading sheet 21 has a second sliding protrusion 211 on both sides and is slidably assembled with the assembly slide groove 12 so that the fixed spreading sheet 21 can be slid along the assembly slide groove 12 to the required position according to actual needs during assembly.

[0035] Furthermore, the middle part of the fixed spreading sheet 21 is provided with at least one locking through hole 212 for locking and fixing together with the bottom wall of the assembly groove 11, so as to lock and fix the fixed spreading sheet 21 to the bottom wall of the assembly groove 11 through the locking through hole 212.

[0036] This utility model designs a fixed spreading sheet 21 with second sliding protrusions 211 on both sides and a locking through hole 212 in the middle. This allows the fixed spreading sheet 21 to slide to the desired position during assembly by utilizing the sliding engagement of the second sliding protrusions 211 with the assembly groove 12. Then, the fixed spreading sheet 21 is locked and fixed to the bottom wall of the assembly groove 11 by the locking through hole 212. Specifically, bolts or screws can be used to lock and fix the fixed spreading sheet 21 to the bottom wall of the assembly groove 11, thereby ensuring that the fixed spreading sheet 21 cannot move along the assembly groove 12 during use.

[0037] In some embodiments of this utility model, a gap is left between the lower surface of each movable spreading piece 22 and fixed spreading piece 21 and the bottom wall of the mounting groove 11 to ensure that the bottom wall of the mounting groove 11 does not obstruct the movement of each movable spreading piece 22, thereby improving the smoothness of each movable spreading piece 22 when it moves and spreads.

[0038] In some embodiments of this utility model, each of the movable fabric sheet 22 and the fixed fabric sheet 21 has an extension 23 extending to the outer surface of the transmission roller body 1 on both sides of its top surface. That is, the extension 23 is located outside the outer surface of the transmission roller body 1. In this way, during use, only the top of the movable fabric sheet 22 and the fixed fabric sheet 21 can contact the fabric, while the outer surface of the transmission roller body 1 will not contact the fabric.

[0039] Furthermore, the top surfaces of the movable fabric piece 22 and the fixed fabric piece 21 each extend upwards at both sides to form an extending protrusion 24, that is, they extend outwards in the radial direction to form an extending protrusion 24. Since the fixed fabric piece 21 needs to be fixed to the bottom wall of the mounting groove 11 by bolts or screws, by designing the top surfaces of the movable fabric piece 22 and the fixed fabric piece 21 to form extending protrusions 24 at both sides, the extending protrusions 24 can provide a certain support for the fabric during actual use, so that the fabric will not completely adhere to the surface of the movable fabric piece 22 and the fixed fabric piece 21, nor will it come into contact with the bolts or screws.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
