Detailed Description of the Invention

[0022] The content of the present utility model will be further described in detail below in conjunction with specific embodiments:

[0023] As Figure 1As shown in the figure, a cloth strip feeding and cutting device includes a base 1, on which a feeding component 2 and a cutting component 3 are arranged. Among them, the feeding component 2 has a material roll 21 for carrying the cloth strip and a feeding driving mechanism 22 for conveying the cloth strip to the cutting component 3, and then the cutting component 3 cuts the cloth strip into a preset length.

[0024] Specifically, as Figure 2 shown, the feeding driving mechanism 22 includes a feeding channel 221 and a feeding driving wheel 222. The feeding channel 221 is set to be a hollow structure with both ends open, and a flared opening 223 is provided at one end close to the material roll 21 to facilitate the entry of the cloth strip. A driving groove 224 is opened at one end of the feeding channel 221 close to the feeding driving wheel 222, so that the feeding driving wheel 222 can directly abut against the cloth strip in the feeding channel 221 and drive the cloth strip to run towards the cutting component 3 by its own rotation. In this embodiment, the axis of the feeding driving wheel 222 is arranged in the vertical direction, and a rubber coating is provided at the rim of the feeding driving wheel 222 to increase the friction coefficient with the cloth strip.

[0025] Moreover, the feeding driving wheel 222 is connected to a clutch 23, and the clutch 23 can drive the feeding driving wheel 222 to move towards or away from the driving groove 224 in the horizontal direction. This enables the cloth strip to be fed without frequently starting and stopping the feeding driving wheel 222 during the feeding process, and also avoids the problem of uneven cloth strip conveying speed when the feeding driving wheel 222 is accelerating and decelerating.

[0026] Specifically, the base 1 includes a horizontal tabletop and a mounting frame vertically fixed on the tabletop. The servo motor of the feeding driving wheel 222 is hinged to the mounting frame, so that the feeding driving wheel 222 can swing around the vertical axis of the hinge end. As Figure 4 shown, the clutch 23 includes a driving cylinder 231 and a return spring 232. Among them, one end of the driving cylinder 231 is fixed to the mounting frame on the base 1, and the other end abuts against the feeding driving wheel 222. One end of the return spring 232 is fixed to the mounting frame on the base 1, and the other end abuts against the feeding driving wheel 222, and gives the feeding driving wheel 222 a torque in the opposite direction to that of the driving cylinder 231 on the feeding driving wheel 222.

[0027] As Figure 3As shown, the feeding driving mechanism 22 is arranged at one end of the feeding driving mechanism 22 away from the material roll 21, and has a cutting knife 31 and a cutting knife driver 32 for driving the cutting knife 31 to act. Among them, the cutting knife 31 is arranged along the vertical direction and corresponds to the opening end of the feeding channel 221 away from the material roll 21. The cutting knife 31 includes a first cutting edge 311 and a second cutting edge 312 that cooperate in motion. Among them, the second cutting edge 312 is fixed to the mounting bracket on the base 1. In other embodiments, the second cutting edge 312 can also be directly constructed as a part of the mounting bracket. One end and the middle part of the first cutting edge 311 are hinged to the base 1 and the execution end of the cutting knife driver 32 respectively, and one end of the cutting knife driver 32 away from the cutting knife 31 is hinged to the base 1 or the mounting bracket. When the execution end of the cutting knife driver 32 acts, it can push the first cutting edge 311 to perform a shearing motion relative to the second cutting edge 312. In this embodiment, the cutting knife driver 32 uses a cylinder.

[0028] During use:

[0029] Step 1: Manually pull the cloth strip on the material roll 21 into the feeding channel 221 and at least pass it to the driving groove 224 so that the feeding driving wheel 222 can drive the cloth strip to run.

[0030] Step 2: Operate the clutch 23 so that the feeding driving wheel 222 abuts against the cloth strip in the driving groove 224, and start the feeding driving wheel 222 so that the cloth strip moves towards the cutting assembly 3.

[0031] Step 3: When the cloth strip passes through the preset length of the cutting assembly 3, the first cutting edge 311 of the cutting assembly 3 is driven by the cutting knife driver 32 to cooperate with the second cutting edge 312 to perform a shearing action, and cut off the cloth strip of the preset length.
