Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0034] See also Figure 2 In this embodiment, an automatic feeding device for a pipe cutting machine includes a box body 1 and a feeding mechanism arranged inside the box body 1. A feeding hole 2 is opened on the right side of the box body 1;

[0035] See also Figure 2-4 The feeding mechanism includes a lower ring plate 301 fixed between the front and rear inner walls of the feeding hole 2, an adjusting cylinder 302 fixed on the right inner wall of the box body 1, an upper ring plate 303 fixed at the bottom end of the output shaft of the adjusting cylinder 302, a plurality of feeding rollers 304 rotatably connected between the front and rear inner walls of the lower ring plate 301 and the upper ring plate 303, a feeding motor 305 fixed on the back of the lower ring plate 301, a worm 306 fixed at the right end of the output shaft of the feeding motor 305 and a plurality of worm wheels 307 rotatably connected to the back of the lower ring plate 301 and meshing with the worm 306, and a plurality of feeding rollers 304 on the lower ring plate 301. The rear ends of 04 are respectively fixed to multiple worm gears 307. When in use, the pipe is inserted into the box body 1 from the feeding hole 2, and the pipe is located between the upper ring plate 303 and the lower ring plate 301. The adjusting cylinder 302 is then controlled to drive the upper ring plate 303 to move downward, and then the pipe is clamped by the feeding rollers 304 on the upper ring plate 303 and the lower ring plate 301. Further, the feeding motor 305 is controlled to drive the worm 306 to rotate, and the worm 306 drives multiple worm gears 307 to rotate synchronously in the same direction, thereby driving the multiple feeding rollers 304 on the lower ring plate 301 to rotate and automatically feed into the box body 1.

[0036] It should be noted that the control method of the present application is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present application is mainly used to protect mechanical devices, so the present application will no longer explain the control method and circuit connection in detail.

[0037] In this embodiment, a box door is hinged on the front of the box body 1, the loading hole 2 is a rectangular hole, the lower ring plate 301 and the upper ring plate 303 are opposite to each other up and down, and the lower ring plate 301 and the upper ring plate 303 both pass through the loading hole 2 from left to right, a rubber sleeve is fixed on the outer peripheral wall of the loading roller 304, and a support plate fixed to the front and the back of the lower ring plate 301 is rotatably connected to the outer peripheral wall of the worm gear 306.

The top surface of the box body 1 is provided with a sliding hole 312 for the threaded block 310 to penetrate and slide left and right inside it. When the pipe is automatically transported to the inside of the box body 1, its left end will abut against the pressure baffle plate 311. When the left end of the pipe abuts against the pressure baffle plate 311, the feeding motor 305 stops feeding. At this time, the pipe can be cut. When it is necessary to cut pipes of different lengths, the screw rod 309 is rotated, and the screw rod 309 drives the threaded block 310 to slide horizontally inside the sliding hole 312, thereby driving the pressure baffle plate 311 to slide left and right, changing the length of the pipe that can be inserted into the box body 1, which is convenient for cutting pipes of different lengths according to production requirements.

[0039] It should be noted that a pressure sensor is installed on the pressure baffle 311. The pressure sensor belongs to the existing public technology.

[0041] See also Figure 3 The utility model also provides a roller processing pipe cutting machine, including the above-mentioned automatic feeding device of the pipe cutting machine. The roller processing pipe cutting machine also includes a cutting cylinder 4 and a cutting mechanism arranged on the cutting cylinder 4. The feeding device automatically transports the pipe to be cut to the cutting position, and the cutting cylinder 4 drives the cutting mechanism to cut. The automatic feeding device of the pipe cutting machine automatically transports the pipe to the inside of the box 1 for positioning and feeding, and cooperates with the cutting mechanism to perform automatic cutting, which effectively improves the efficiency of cutting the pipe.

When it is necessary to cut the pipe, the cutting motor 502 drives the transmission plate 503 to rotate, and the transmission plate 503 drives the transmission shaft 507 to rotate through the slot 509, and the transmission shaft 507 drives the cutting blade 508 to rotate, and then the cutting cylinder 4 is controlled to drive the cutting chamber 501 to move downward, so that the rotating cutting blade 508 moves downward to cut the pipe. When the cutting blade 508 needs to be maintained, the abutment plate 506 is moved to the left to compress the spring 505 and the telescopic rod 504, and at the same time the transmission shaft 507 is disengaged from the slot 509. At this time, the cutting blade 508 can be removed from the outer wall of the transmission shaft 507 for maintenance. After the maintenance is completed, the above operation is reversed, and the transmission shaft 507 is inserted into the slot 509 after passing through the socket 510 through the spring 505.

[0043] In this embodiment, the bottom surface of the cutting chamber 501 is open, the telescopic rod 504, the transmission shaft 507 and the output shaft of the cutting motor 502 are all located on the same central axis, the transmission shaft 507 is a square shaft, the slot 509 is a square slot, and the socket 510 is a square hole.

[0044] The working principle of the above embodiment is:

[0045] (1) When in use, insert the pipe into the box body 1 through the feeding hole 2, and make the pipe be located between the upper ring plate 303 and the lower ring plate 301, then control the regulating cylinder 302 to drive the upper ring plate 303 to move downward, and then clamp the pipe through the feeding rollers 304 on the upper ring plate 303 and the lower ring plate 301, and further control the feeding motor 305 to drive the worm 306 to rotate, and the worm 306 drives multiple worm wheels 307 to rotate synchronously in the same direction, thereby driving multiple feeding rollers 304 on the lower ring plate 301 to rotate into the box body 1 When the pipe is automatically transported to the inside of the box 1, its left end will abut against the pressure baffle 311. When the left end of the pipe abuts against the pressure baffle 311, the feeding motor 305 stops feeding, and the pipe can be cut at this time. When it is necessary to cut pipes of different lengths, the screw 309 is rotated, and the screw 309 drives the threaded block 310 to slide horizontally inside the sliding hole 312, thereby driving the pressure baffle 311 to slide left and right, changing the length of the pipe that can be inserted into the box 1, so as to facilitate cutting of pipes of different lengths according to production requirements;

[0046] (2) When it is necessary to cut the pipe, the cutting motor 502 drives the transmission plate 503 to rotate, and the transmission plate 503 drives the transmission shaft 507 to rotate through the slot 509, and the transmission shaft 507 drives the cutting blade 508 to rotate, and then the cutting cylinder 4 is controlled to drive the cutting chamber 501 to move downward, so that the rotating cutting blade 508 moves downward to cut the pipe. When the cutting blade 508 needs to be maintained, the abutment plate 506 is moved to the left to compress the spring 505 and the telescopic rod 504, and at the same time the transmission shaft 507 is disengaged from the slot 509. At this time, the cutting blade 508 can be removed from the outer wall of the transmission shaft 507 for maintenance. After the maintenance is completed, the above operation is reversed, and the transmission shaft 507 is inserted into the slot 509 after passing through the insertion hole 510 through the spring 505.
