[0034] The following is for reference Figures 1 to 4 This utility model will now be described.

[0035] An automatic pipe cutting machine includes a body 1. From left to right, the upper end of the body 1 is provided with a guide wheel assembly, a first guide block 2, and a connecting frame 3. The first guide block 2 and the connecting frame 3 are fixed to the upper end of the body 1. The body 1 is provided with a transmission assembly and a cutting assembly. The connecting frame 3 is formed with a slide groove 301. A first slider 4 is slidably connected to the slide groove 301. A positioning plate 5 is fixed on the side wall of the first slider 4. The connecting frame 3 is provided with a positioning assembly and a pushing assembly.

[0036] When the rubber tube 6 needs to be cut, one end of the rubber tube 6 is fitted into the guide wheel assembly. The transmission assembly is started, which drives the guide wheel assembly to rotate, thereby driving the rubber tube 6 to be conveyed. One end of the rubber tube 6 passes through the first guide block 2 and abuts against the positioning plate 5, which can push the positioning plate 5 to move. When the positioning assembly detects that the positioning plate 5 has moved to the required position, it controls the transmission assembly to stop working and starts the cutting assembly to cut the rubber tube 6. Then, the pushing assembly pushes the cut rubber tube 6 to disengage the rubber tube 6 from the connecting frame 3, so that the rubber tube 6 can be cut continuously.

[0037] By incorporating guide rollers and a pushing assembly, the rubber tube 6 can be automatically conveyed and pushed after cutting. This solves the problem that existing technologies require manual pushing of the rubber tube 6 and manual removal of the cut rubber tube 6. As a result, the fixed-length tube cutting work can be completed automatically, improving cutting efficiency and safety during use.

[0038] The guide wheel assembly includes multiple guide wheels 7 arranged symmetrically in two groups, with two adjacent guide wheels 7 abutting against each other. The side wall of the guide wheel 7 is formed with a groove 701 that matches the rubber tube 6. The lower end of the guide wheel 7 is fixed with a connecting shaft 8, which is rotatably connected to the machine body 1. The transmission component is set on the connecting shaft 8.

[0039] When it is necessary to drive the rubber tube 6 for conveying, one end of the rubber tube 6 is fitted between two grooves 701 and abuts against each other. The transmission component is started, thereby driving multiple guide wheels 7 of one group to rotate clockwise, and at the same time driving multiple guide wheels 7 of the other group to rotate counterclockwise, thereby driving the rubber tube 6 for conveying.

[0040] The transmission assembly includes pulleys 9 fixed on the extended end of the connecting shaft 8 passing through the body 1. A belt 10 is connected between two adjacent pulleys 9 in the same group. A gear 11 is fixed on one of the pulleys 9 in each group. The two gears 11 mesh with each other. A motor 12 is fixed inside the body 1. The output end of the motor 12 is fixed to the lower end of one of the gears 11.

[0041] When the guide wheel assembly needs to be operated, the motor 12 is started, which drives one of the gears 11 to rotate. The rotation of one gear 11 drives one of the pulleys 9 to rotate. The rotation of one pulley 9 drives one group of multiple guide wheels 7 to rotate clockwise via the belt 10. At the same time, the rotation of gear 11 drives another gear 11 to rotate. The rotation of another gear 11 drives another pulley 9 to rotate. The rotation of another pulley 9 drives another group of multiple guide wheels 7 to rotate counterclockwise via the belt 10, thereby driving the guide wheel assembly to work, which in turn drives the rubber hose 6 for conveying.

[0042] The cutting assembly includes a hydraulic cylinder 13 fixed inside the machine body 1. A cutting blade 14 is fixed on the hydraulic rod 1301 of the hydraulic cylinder 13. A cutting groove 101 is formed at the upper end of the machine body 1 for the cutting blade 14 to pass through.

[0043] When it is necessary to cut the rubber tube 6, the hydraulic cylinder 13 is activated, and the cutting blade 14 is moved upward and passes through the cutting groove 101 via the hydraulic rod 1301, thereby cutting the rubber tube 6.

[0044] The positioning assembly includes a second slider 15 slidably connected to the slide groove 301, a proximity sensor 16 mounted on the second slider 15, the proximity sensor 16 being electrically connected to a controller, the controller being electrically connected to the motor 12, and a screw 17 screwed to the lower end of the second slider 15, the screw 17 passing through the protruding end of the second slider 15 and abutting against the lower end of the connecting frame 3.

[0045] When the rubber tube 6 needs to be cut to a fixed length, rotate screw 17 to disengage it from the connecting frame 3, and move the second slider 15 to the desired position. Then rotate screw 17 again so that the end of screw 17 abuts against the lower end of the connecting frame 3, thereby fixing the second slider 15. When the rubber tube 6 pushes the positioning plate 5 to move, the proximity sensor 16 detects that the positioning plate 5 has moved to the desired position and controls the motor 12 to stop working through the controller. At the same time, the cutting assembly is started to cut the rubber tube 6, thereby effectively cutting the rubber tube 6 to a fixed length.

[0046] The pushing assembly includes a servo electric cylinder 18 fixed to the upper end of the connecting frame 3. An arc-shaped pushing plate 19 is fixed on the push rod 1801 of the servo electric cylinder 18. A notch 302 is formed on the side wall of the connecting frame 3 for the arc-shaped pushing plate 19 to pass through.

[0047] When it is necessary to push the cut rubber tube 6, the servo electric cylinder 18 is activated, and the arc-shaped push plate 19 is moved by the push rod 1801, so that the cut rubber tube 6 can be pushed and the cut rubber tube 6 is disengaged from the connecting frame 3.

[0048] The two ends of the notch 302 are formed with arc-shaped folded edges 303.

[0051] When the rubber tube 6 needs to be transported through the guide wheel assembly, the rubber tube 6 is first guided by the second guide block 20 to prevent the rubber tube 6 from pulling on the guide wheel assembly.

[0052] Working principle:

[0053] When the rubber tube 6 needs to be cut, rotate screw 17 to disengage it from the connecting frame 3, moving the second slider 15 to the desired position. Then rotate screw 17 again, so that the end of screw 17 abuts against the lower end of the connecting frame 3, thereby fixing the second slider 15. Place one end of the rubber tube 6 between the two grooves 701, abutting against each other. Start motor 12, which drives one gear 11 to rotate. The rotation of gear 11 drives one pulley 9 to rotate. The rotation of pulley 9 drives a group of guide wheels 7 to rotate clockwise via belt 10. Simultaneously, the rotation of gear 11 drives another gear 11 to rotate, which in turn drives another pulley 9 to rotate. The rotating belt 10 drives multiple guide wheels 7 of another set to rotate counterclockwise, thereby driving the rubber tube 6 to be transported. One end of the rubber tube 6 passes through the first guide block 2 and abuts against the positioning plate 5, thereby pushing the positioning plate 5 to move. When the proximity sensor 16 detects that the positioning plate 5 has moved to the required position, the controller controls the motor 12 to stop working and starts the hydraulic cylinder 13. The hydraulic rod 1301 drives the cutting blade 14 to move upward and pass through the cutting groove 101, thereby cutting the rubber tube 6. Then, the servo electric cylinder 18 is started, and the push rod 1801 pushes the arc-shaped push plate 19 to move, thereby pushing the cut rubber tube 6 and disengaging the cut rubber tube 6 from the connecting frame 3, so that the rubber tube 6 can be cut continuously.
