The described embodiment is a partial embodiment of the utility model, not all embodiments.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please refer to the attached Figure 1-4 The present embodiment provides a cloth feeding and cutting mechanism, which is mainly used for cutting and feeding cloth. The cloth in the present embodiment includes but is not limited to non-woven cloth, and can also be fiber cloth, cotton cloth, etc.

[0034] The cloth feeding and cutting mechanism includes a cloth discharging module 1, which can output the cloth to a certain length to prevent waste due to a large cutting length or the situation where the battery and other mechanisms cannot be cleaned due to a small cutting length. The cloth discharging module 1 includes a first driving component 110, a second driving component 120, a cloth discharging wheel 130 and a pressing wheel 140. The cloth discharging wheel 130 and the pressing wheel 140 are arranged opposite to each other and a gap is left between them to form a cloth discharging channel. The first driving component 110 is connected to the cloth discharging wheel 130 to drive the cloth discharging wheel 130 to rotate, and the second driving component 120 is connected to the pressing wheel 140 to drive the pressing wheel 140 to move closer to or away from the cloth discharging wheel 130.

[0035] It is understandable that the first drive assembly 110 and the second drive assembly 120 can be motors, screw guides, cylinders, etc., which are not limited in this embodiment. It is only necessary to drive the above-mentioned pressing wheel 140 and the cloth-discharging wheel 130 to complete related actions. Exemplarily, the first drive assembly 110 is a drive motor, and the drive end of the drive motor is connected to the cloth-discharging wheel 130 to rotate the cloth-discharging wheel 130; or it can also be a combination of a cylinder and a connecting rod, and the cylinder extends to drive the connecting rod to swing, thereby driving the cloth-discharging wheel 130 to rotate, etc., which is not limited in this embodiment. The cloth-discharging wheel 130 is driven to rotate a certain angle by a drive mechanism such as a drive motor, thereby limiting the length of the output cloth. Exemplarily, the second driving assembly 120 is a cylinder, and the output end of the cylinder is connected to a connecting block, which is connected to the two ends of the pressing wheel 140 through the connecting block, thereby driving the pressing wheel 140 to move closer to or away from the cloth-discharging wheel 130, pressing the cloth in the cloth-discharging channel, so that the cloth-discharging wheel 130 can better output the cloth, and improve the accuracy of the output cloth length. There is a cloth-discharging channel between the cloth-discharging wheel 130 and the pressing wheel 140. When in use, the external cloth is first placed in the cloth-discharging channel, and the second driving assembly 120 drives the pressing wheel 140 to press toward the cloth-discharging wheel 130, and the cloth-discharging wheel 130 and the pressing wheel 140 press the cloth. At this time, the cloth-discharging wheel 130 rotates under the drive of the first driving assembly 110, thereby outputting the cloth.

[0036] The feeding module 2 is used to transport the cloth transmitted by the cloth discharging module 1 so that the cloth enters the next process, and it is arranged on one side of the cloth discharging module 1. Among them, the feeding module 2 includes a discharging platform 210 for placing the cloth, and the discharging platform 210 is used to place the cloth. It can be understood that the discharging platform 210 can limit the cloth by setting a limit block, a suction cup, a pressure block, etc. to prevent it from swinging during the cutting process and affecting the accuracy. Preferably, it is arranged opposite to the cloth discharging channel of the cloth discharging module 1. When the cloth is output from the cloth discharging channel, the cloth is directly output to the discharging platform 210, and the cloth is cut by the cutting module 3 and other equipment to complete the discharging.

[0037] The cutting module 3 is used to automatically cut the cloth. It is arranged between the cloth discharging module 1 and the feeding module 2. By determining the distance between the cutting module 3 and the end of the cloth, the cutting length of the cloth can be determined. The cutting module 3 includes a first cutter 310 and a cutter driving assembly 320. The cutter driving assembly 320 is connected to the first cutter 310 in a transmission manner so that the cutter cuts the cloth between the material discharging platform 210 and the pressing wheel 140. Specifically, the cutter driving assembly 320 can be a cylinder, a gear rack, a motor, a screw guide rail, etc. Exemplarily, the cutter driving assembly 320 includes a cylinder, a guide rail and a slider. The guide rail is arranged along the cutting direction. The slider is movably connected to the guide rail. The first cutter 310 is arranged on the slider. The driving end of the cylinder is connected to one end of the first cutter 310. The cylinder is extended and retracted to drive the cutter to move along the guide rail direction, thereby cutting the cloth.

[0038] In some embodiments, a friction layer 131 is provided on the surface of the cloth discharging wheel 130. The friction layer 131 may be a plurality of friction strips, friction blocks or diamond sand etc. provided on the surface of the wheel body, and the surface of the wheel body is provided with a rough surface to increase the friction force, so that the cloth is more easily moved with the rotation of the cloth discharging wheel 130.

[0039] During use, the cloth is first placed in the cloth outlet channel, and the second driving component 120 drives the pressing wheel 140 to move toward the cloth outlet wheel 130, pressing the cloth between the pressing wheel 140 and the cloth outlet wheel 130. At this time, the first driving component 110 drives the cloth outlet wheel 130 to rotate, and the cloth moves along the cloth outlet channel and falls into the material discharge platform 210. When the cloth moves to a certain length, the cutter driving component drives the first cutter 310 to move downward to cut the cloth.

[0040] This embodiment can automatically cut the cloth by setting the cloth discharging module 1, feeding module 2 and cutting module 3 to improve the cutting efficiency; the cloth is discharged by setting the pressing wheel 140 and the cloth discharging wheel 130, and the cloth is output to a certain length by the rotation of the cloth discharging wheel 130. The cloth output length varies with the number of rotations, which improves the universality of the equipment and can make the cloth output length consistent each time to avoid the phenomenon of cloth waste. The time and length of cloth discharging can also be controlled by parameters, which can shorten the time waste of pause in terms of efficiency, and all the cloth can be cut and collected uniformly; the length of the cut specifications is kept consistent.
