DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Please see Figures 1 to 4 The utility model is a multi-layer cloth folding machine, which includes a frame 1, a feeding conveyor 2 installed on the frame 1, a clamping device 3 arranged on one side of the feeding conveyor 2, and a folding mechanism 4 located on one side of the clamping device 3.

[0026] Please see Figure 1 The frame 1 supports the cabinet 11 and the hood 12. The support cabinet 11 is in a horizontal state and is used to support the feed conveying device 2, the clamping device 3 and the folding mechanism 4. The hood 12 is fixedly connected to the support cabinet 11 and is used to protect and support the feed conveying device 2, the clamping device 3 and the folding mechanism 4 to avoid contamination during the production process.

[0027] Please see Figure 1 to Figure 2The feeding conveying device 2 includes a first feeding conveying part 21 and a second feeding conveying part 22. The first feeding conveying part 21 and the second feeding conveying part 22 have the same structure and are symmetrically arranged. They include a transmission active shaft 211, a transmission passive shaft 212, a conveyor belt 213 surrounding the transmission active shaft 211 and the transmission passive shaft 212, and a transmission motor 214 driving the transmission active shaft 211. The transmission active shaft 211 and the transmission passive shaft 212 are fixedly connected to the frame 1 at one end, and the other end thereof extends horizontally outward. In this embodiment, the diameter of the transmission active shaft 211 is larger than the diameter of the transmission passive shaft 212 and the bottom is in a relatively parallel state. The transmission motor 214 is fixedly connected to the frame 1 and drives the transmission active shaft 211 to rotate. The transmission active shaft 211 drives the transmission passive shaft 212 to move synchronously through the conveyor belt 213. A feeding gap 215 is formed between the first feeding conveying part 21 and the second feeding conveying part 22, and the space of the feeding gap 215 gradually shrinks as it extends toward the transmission passive shaft 212.

[0028] Please see Figure 1 and Figure 3 The clamping device 3 includes a first clamping part 31 and a second clamping part 32. The first clamping part 31 and the second clamping part 32 have the same structure and are symmetrically arranged. They include a clamping active shaft 311, a clamping passive shaft 312, a clamping belt 313 surrounding the clamping active shaft 311 and the clamping passive shaft 312, and a clamping motor 314 driving the clamping active shaft 311. The clamping active shaft 311 and the clamping passive shaft 312 are both fixedly connected to the frame 1 at one end and extend horizontally outward at the other end. The clamping motor 314 is fixedly connected to the frame 1 and drives the clamping active shaft 311 to rotate. The clamping active shaft 311 drives the clamping passive shaft 312 to move synchronously through the clamping belt 313. The spacing between the first clamping part 31 and the second clamping part 32 is the same to form a clamping gap 315.

[0029] Please see Figure 4 The folding mechanism 4 includes a bottom material moving member 41, a material pulling member 42 arranged above the bottom material moving member 41, and a material pushing member 43 located between the bottom material moving member 41 and the material pulling member 42. The bottom material moving member 41 is a transmission device of a certain specification, which has a horizontal conveyor belt 411. The material pulling member 42 includes a rotatable rotating shaft 421, a pressing plate 422 sleeved on the rotating shaft 421, and an air suction hole 423 arranged on the lower surface of the pressing plate 422. One end of the rotating shaft 421 is movably connected to the frame 1, and the other end extends horizontally outward. The pressing plate 422 can rotate around the rotating shaft 421. The number and position of the air suction holes 423 are changed according to needs. In this embodiment, the air suction holes 423 are divided into two rows and are relatively parallel.

[0030] The pusher 43 is a plate that extends from the outside of the frame 1 through the frame 1 to between the bottom moving member 41 and the pulling member 42 . Its length is the same as that of the bottom moving member 41 . The pusher 43 can move horizontally between the bottom moving member 41 and the pulling member 42 .

[0031] The folding mechanism 4 further includes a material stopper 44 , which is a plate that extends from the outside of the frame 1 through the frame 1 to one side of the pressing plate 422 . Its length is the same as that of the pressing plate 422 , and the material stopper 44 can move toward the pressing plate 422 .

[0032] When the utility model is used, a multi-layer cloth folding machine, the cloth enters between the first feeding conveyor part 21 and the second feeding conveyor part 22, and the distance between them gradually decreases as it extends toward the direction of the conveying passive shaft 212. The first feeding conveyor part 21 and the second feeding conveyor part 22 clamp the cloth and send it between the first clamping part 31 and the second clamping part 32. The first clamping part 31 and the second clamping part 32 convey the material to the bottom material moving part 41. At this time, the pressing plate 422 is parallel to the bottom material moving part 41. After the cloth moves into place, the pressing plate 422 absorbs the material through the suction hole 423, and the pressing plate 422 rotates around the rotating shaft 421. The cloth adsorbed by it moves around the rotating shaft 421, and the material blocking member 44 moves toward the direction of the pressing plate 422. The cloth adsorbed by the pressing plate 422 is perpendicular to the cloth clamped by the clamping device 3. The material pushing member 43 is located above the cloth, and it moves horizontally between the bottom material moving member 41 and the material pulling member 42, pushing the cloth toward the bottom material moving member 41 to complete the first folding. The pressing plate 422 drives the adsorbed cloth to return along the previous path to complete the second folding. After the folding is completed, the material pushing member 43 and the material blocking member 44 return to the original path and break away from the contact with the cloth.

[0033] The utility model is a multi-layer cloth folding machine with the characteristic of high efficiency. The cloth is moved by a bottom material moving piece so that a pressing plate absorbs the cloth and changes the position of the cloth. Then, a material pushing piece and a material pulling piece are used to fix and push the cloth respectively so that the cloth is folded, thereby reducing the movement of the cloth and improving the efficiency of the cloth folding.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
