[0004] The technical solution adopted by the utility model is as follows:

[0005] A PVC pipe cutting machine includes a bottom plate. On the top of the bottom plate, side plates are vertically and fixedly connected to both the left and right sides. On the front and back sides of the top of the bottom plate, a front fixing plate and a rear fixing plate are respectively vertically and fixedly connected. The two side plates, the front fixing plate and the rear fixing plate enclose a rectangle. In the middle of the front side wall of the front fixing plate, a feeding hole is provided. Between the two side plates, there are several upper rotating shafts and several lower rotating shafts. The upper rotating shafts are directly above the lower rotating shafts, and the upper rotating shafts and the lower rotating shafts are arranged equidistantly in the front and back. The left and right ends of the upper rotating shafts and the lower rotating shafts are respectively rotatably connected to the two side plates. The outer walls of the upper rotating shafts and the lower rotating shafts are fixedly sleeved with rollers, and the upper and lower rollers are in clearance fit. On the outer wall of the roller, a clamping groove one, a clamping groove two and a clamping groove three are successively arranged from right to left. At the front and rear ends of the left side wall of the left side plate, a motor one and a motor two are respectively fixedly connected. The output shaft of the motor one is fixedly connected to the left end of the front lower rotating shaft, and the output shaft of the motor two is fixedly connected to the left end of the rear lower rotating shaft. The right ends of the rear lower rotating shaft and the upper rotating shaft penetrate through the side plate and are fixedly connected with gears, and the two gears are meshed with each other. In the middle of the top of the rear fixing plate, a fixing frame is fixedly connected. On the top of the fixing frame, a cylinder is fixedly connected.

Detailed implementation manners

[0015] As Figures 1-4As shown: A PVC pipe cutter includes a bottom plate 1. On the top of the left and right sides of the bottom plate 1, side plates 2 are vertically and fixedly connected. On the front and rear sides of the top of the bottom plate 1, a front fixing plate 3 and a rear fixing plate 4 are vertically and fixedly connected respectively. The two side plates 2, the front fixing plate 3 and the rear fixing plate 4 enclose a rectangle. In the middle of the front side wall of the front fixing plate 3, a feeding hole 5 is opened. Between the two side plates 2, there are several upper rotating shafts 6 and several lower rotating shafts 7. The upper rotating shafts 6 are directly above the lower rotating shafts 7. The upper rotating shafts 6 and the lower rotating shafts 7 are arranged equidistantly in the front and rear. The left and right ends of the upper rotating shafts 6 and the lower rotating shafts 7 are respectively rotatably connected to the two side plates 2. On the outer walls of the upper rotating shafts 6 and the lower rotating shafts 7, rollers 8 are fixedly sleeved. The upper and lower rollers 8 are in clearance fit. On the outer wall of the roller 8, a first clamping groove 9, a second clamping groove 10 and a third clamping groove 11 are successively opened from right to left. At the front and rear ends of the left side wall of the left side plate 2, a first motor 12 and a second motor 13 are respectively fixedly connected. The output shaft of the first motor 12 is fixedly connected to the left end of the front lower rotating shaft 7. The output shaft of the second motor 13 is fixedly connected to the left end of the rear lower rotating shaft 7. The right ends of the rear lower rotating shaft 7 and the upper rotating shaft 6 penetrate through the side plate 2 and are fixedly connected with gears 14. The two gears 14 are meshed with each other. In the middle of the top of the rear fixing plate 4, a fixing frame 15 is fixedly connected. On the top of the fixing frame 15, a cylinder 16 is fixedly connected. The bottom end of the output shaft of the cylinder 16 penetrates through the fixing frame 15 and is fixedly connected with a cutting knife 17. On the rear side wall of the rear fixing plate 4, a discharge plate 18 is vertically and fixedly connected. On the top of the discharge plate 18, a cut 22 is opened. The cut 22 is directly below the cutting knife 17 and is in clearance fit with the cutting knife 17. At the rear of the bottom plate 1, there is a collection box 23. The collection box 23 is located below the rear end of the discharge plate 18.

[0016] The first clamping groove 9, the second clamping groove 10 and the third clamping groove 11 are annular semi-circular grooves and their diameters increase in geometric progression in turn.

[0017] On the top of the discharge plate 18, a first material guiding groove 19, a second material guiding groove 20 and a third material guiding groove 21 are successively opened from right to left. The first material guiding groove 19, the second material guiding groove 20 and the third material guiding groove 21 are semi-circular grooves, and their diameters are respectively equal to the diameters of the first clamping groove 9, the second clamping groove 10 and the third clamping groove 11. The centers of the first material guiding groove 19, the second material guiding groove 20 and the third material guiding groove 21 are on the same horizontal line as the centers of the first clamping groove 9, the second clamping groove 10 and the third clamping groove 11 respectively.

[0018] Insert the PVC pipe to be cut into the corresponding diameter-sized clamping grooves from the feed hole 5, namely the first clamping groove 9, the second clamping groove 10, and the third clamping groove 11. The upper and lower clamping grooves clamp the pipe. Start the first motor 12 to drive the front lower rotating shaft 7 to rotate, drive the roller 8 below the front side to rotate, and convey the pipe backward. The pipe moves along multiple rollers 8. The rollers 8 use the clamping grooves to clamp and straighten the pipe until it is sent between the two rollers 8 at the rearmost side. Stop the first motor 12 and start the second motor 13. The second motor 13 drives the rearmost lower rotating shaft 7 to rotate. Since the right ends of the rear lower rotating shaft 7 and the upper rotating shaft 6 are engaged by the gear 14, the rear lower rotating shaft 7 and the upper rotating shaft 6 will rotate synchronously and in opposite directions. The two rollers 8 at the rearmost side clamp the pipe and push the pipe backward to straighten the pipe.

[0019] Due to the use of three clamping grooves with different diameters, the rollers 8 can effectively clamp and drive pipes with different diameters to move forward.

[0020] When the pipe moves below the cutting knife 17, the cylinder 16 drives the cutting knife 17 to move downward and pass through the incision 22 to cut the pipe. After cutting, the cylinder 16 retracts, and the cutting knife 17 returns to the initial position to wait for the next cutting.

[0021] The cut pipe segments continue to move forward under the push of the subsequent pipe and fall into the collection box 23 through the first material guiding groove 19, the second material guiding groove 20, or the third material guiding groove 21 for collection. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
