When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only, and is for the purpose of illustration only, such as the terms "inner", "outer", "left", "right", and the like, and is not intended to be limiting of the invention.

Referring to fig. 1 to 3, a cloth placing mechanism 100 according to an embodiment of the present invention is used for installing a cloth roll 200 and conveying the cloth to a printing platform for printing. The cloth feeding mechanism 100 includes a support assembly 20, two driving rollers 30 rotatably mounted on the support assembly 20, a driving assembly 40 mounted on the support assembly 20 and connected to the driving rollers 30, and a mounting assembly 50 adapted to the driving rollers 30. The driving assembly 40 can drive the driving roller 30 to rotate, and the driving roller 30 drives the mounting assembly 50 to rotate, so that the cloth roll 200 on the mounting assembly 50 can be fed.

In one embodiment, the supporting assembly 20 includes a supporting beam 21, a first supporting plate 22 mounted at one end of the supporting beam 21, and a second supporting plate 23 mounted at the other end of the supporting beam 21, and the driving assembly 40 is mounted on the first supporting plate 22. Wherein, the supporting beam 21 is located between the two driving rollers 30, so that the stress of the whole supporting component 20 is balanced, and the structural strength is good.

In one embodiment, the driving roller 30 is provided with a plurality of anti-slip threads 31 at two ends, the anti-slip threads 31 extend along the axial direction of the driving roller 30, and the anti-slip threads 31 ensure the driving stability of the driving roller 30. Further, bearings 32 are mounted on the ends of the driving roller 30, and the bearings 32 are connected to the first and

second support plates

22 and 23.

In one embodiment, the driving assembly 40 includes a driving motor 41 mounted on the supporting assembly 20, a driving gear 42 connected to the driving motor 41, a transmission gear 43 connected to the driving roller 30, and a chain 44 connected to the driving gear 42 and the transmission gear 43. Wherein the transmission gear 43 is pin-fitted with the driving roller 30. In this embodiment, the driving assemblies 40 are two groups, and each group of driving assemblies 40 is connected to a corresponding driving roller 30. In other embodiments, the driving assembly 40 can be a set, and the two driving rollers 30 can be driven to rotate synchronously by the linking member.

In one embodiment, the mounting assembly 50 includes a mounting shaft 51, and two mounting rollers 52 disposed at two ends of the mounting shaft 51, the mounting rollers 52 are abutted to two portions of the driving roller 30 where the anti-slip patterns 31 are disposed, and a diameter of the mounting rollers 52 is larger than a diameter of the cloth roll 200. Furthermore, the mounting roller 52 is provided with a plurality of receiving holes 53, the receiving holes 53 are annularly arranged, and in the embodiment, three receiving holes 53 are provided. Through the arrangement of the bearing holes 53, the hand is stressed when the hand is assembled, disassembled and replaced, and the convenience of assembling, disassembling and replacing is improved.

When the cloth feeding mechanism 100 is used, the cloth roll 200 is fitted around the mounting shaft 51, and then the cloth roll 200 is fixed to the mounting shaft 51 by the mounting roller 52, and then the whole cloth roll is placed on the two driving rollers 30. The driving assembly 40 drives the two driving rollers 30 to synchronously rotate in the same direction, and the mounting roller 52 rotates along with the driving roller, so that the cloth roll 200 is driven to be unreeled and fed. The cloth roll 200 can be quickly placed on the driving roller 30 or quickly detached from the driving roller 30 through the arrangement of the mounting assembly 50, so that the cloth roll can be conveniently replaced. The anti-slip threads 31 can ensure that the mounting roller 52 does not slip when the driving roller 30 is driven, and the transmission is stable. Because the diameter of the installation roller 52 is larger than that of the cloth roll 200, a gap is formed between the cloth and the driving roller 30, the cloth cannot contact with the driving roller 30, the printing effect is prevented from being influenced by the wrinkling of the cloth in the printing process, the printing quality is good, and the efficiency is high.
