[0032] To make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only one embodiment of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0033] As used herein, an "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present application. In the description of the embodiments of the present application, it should be understood that terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first," "second," and "third" may explicitly or implicitly include one or more of such features. Moreover, terms such as "first," "second," and "third" are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way may be interchanged where appropriate so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "comprising" and "being" and any variations thereof are intended to cover non-exclusive inclusion.

[0034] As Figure 1 shown, this embodiment provides a new type of cloth numbering machine, including a machine table 1. The machine table 1 includes a cloth placement table surface 11 and a drive mechanism mounting frame 12. The cloth is stacked on the cloth placement table surface 11. In other embodiments, the cloth can also be stacked on an extended surface that is horizontal with the mounting table surface 11, such as by adding a pile platform. The drive mechanism mounting frame 12 is installed above the cloth placement table surface 11. A material turning mechanism 2 and a pad printing mechanism 3 are installed between the cloth placement table surface 11 and the drive mechanism mounting frame 12. The material turning mechanism 2 is used to turn over the stacked cloth layer by layer, and the pad printing mechanism 3 is used to print number marks or patterns on each layer of cloth.

[0035] As Figure 2As shown, the material turning mechanism 2 includes a spider robot arm 21 and a material taking mechanism 22 fixed on the spider robot arm 21. The spider robot arm 21 includes 4 groups of driving motors, namely a first driving motor 211, a second driving motor 212, a third driving motor 213 and a fourth driving motor 214. Each group of driving motors is respectively installed on the driving mechanism mounting frame 12. The first driving motor 211, the second driving motor 212, the third driving motor 213 and the fourth driving motor 214 are respectively connected to the mounting block 219 through a first driving arm 215, a second driving arm 216, a third driving arm 217 and a fourth driving arm 218. The spider robot arm 21 has multiple degrees of freedom. In the case of relatively fluffy fabric, it can still adapt to the thickness of the fabric, so as to complete the material taking well. In this embodiment, the material taking mechanism 22 is a needle punching material taking mechanism. In a preferred embodiment of this embodiment, after the material taking mechanism 22 picks up a layer of fabric, the spider robot arm 21 drives the fabric to first move away from the surface of the stacked fabric, and then turns the fabric away from the machine table 1. In this embodiment, the direction away from the machine table 1 is the direction of separating from the machine table, thereby realizing the turning of the fabric.

[0036] As Figure 3 shown, the pad printing mechanism 3 includes a PPU robot arm 31 and a pad printing rubber head 32 fixed on the movable end of the PPU robot arm 31. The pad printing rubber head 32 is installed on the movable end of the PPU robot arm 31 through a fixing plate 33. After the pad printing rubber head 32 prints numbers on the fabric, driven by the PPU robot arm 31, the pad printing rubber head 32 first moves away from the upper surface of the fabric, and then moves in a direction opposite to the material turning direction of the spider robot arm 21. This avoids the spider robot arm 21 touching the pad printing rubber head 32 when turning the fabric, thereby realizing the close cooperation between the numbering mechanism 3 and the material turning mechanism 2.

[0037] A first drive motor 310 is installed on the PPU robot arm 31. An output end of the first drive motor 310 is provided with a swing arm 311. A hollow groove is arranged on the swing arm 311, which can provide a swinging path for the drive mechanism. The swing arm 311 is movably installed with a mounting block 312 through the hollow groove. A pair of first slide rails 313 are fixedly installed on the mounting block 312. The first slide rails 313 are arranged in the vertical direction. A pair of second slide rails 314 are also arranged in the horizontal direction perpendicular to the first slide rails 313. A fixing block 315 is arranged between the first slide rails 313 and the second slide rails 314. A first slider and a second slider are respectively installed on two sides of the fixing block 315. The first slider is slidably matched with the first slide rail 313 to move in the vertical direction, and the second slider is slidably matched with the second slide rail 314 to move in the horizontal direction. One end of the first slide rail 313 close to the fabric placement table 11 is installed with a fixing plate 33. A pad printing rubber head 32 is fixedly installed on the fixing plate 33. In this embodiment, the material of the pad printing rubber head 32 is silica gel.

[0038] An etching plate 34 for the pad printing rubber head 32 to transfer ink is also arranged on the fabric placement table 11. The pad printing rubber head 32 moves horizontally towards the etching plate 34 through the second slide rail 314 in the PPU robot arm 31, and moves vertically towards the etching plate 34 through the first slide rail 313. When the pad printing rubber head 32 moves directly above the etching plate 34 vertically, the second slide rail 314 of the PPU robot arm 31 approaches the etching plate 34, and the pad printing rubber head 32 transfers ink. Subsequently, an ink cup drive mechanism 36 drives the ink cup 35 to scrape ink above the etching plate 34. The ink cup drive mechanism 36 reciprocates on the etching plate 34 to realize reciprocating ink scraping on the etching plate 34.

[0039] As Figure 4As shown, the ink cup driving mechanism 36 includes an ink cup driving motor 361 installed on the side of the fabric placement tabletop 11 facing away from the etching plate 34. A first synchronous pulley 362 is provided at the output end of the ink cup driving motor 361. The first synchronous pulley 362 is connected to a second synchronous pulley 364 fixed on the installation tabletop through a synchronous belt 363. A pushing plate 365 is fixed on the synchronous belt 363. The pushing plate 365 is installed on a third slide rail 367 through a third slider 366. The third slide rail 367 is installed on the fabric placement tabletop 11. The ink cup 35 is installed on the pushing plate 365. The pushing plate 365 includes a pair of parallel pushing blocks. The pair of pushing blocks are respectively installed on the third slide rail 367 through the third slider 366. The ink cup driving motor 361 rotates reciprocally, driving the pushing plate 365 to reciprocate on the third slider 366 and the third slide rail 367 through the synchronous pulleys and the synchronous belt 363, and further driving the ink cup 35 located on the pushing plate 365 to scrape the ink reciprocally on the etching plate 34.

[0040] The above embodiments are only for illustrating the technical concept and features of the present application, and the purpose is to enable those familiar with this technology to understand the content of the present application and implement it accordingly, and it should not be used to limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting.
