A cutting blade 17 is fixedly connected to the position of the first shaft rod 15 corresponding to the first through groove 13, and a conveying rubber roller 18 is fixedly connected to the position of the second shaft rod 16 corresponding to the second through groove 14. The power mechanism is used to drive the first shaft rod 15 and the second shaft rod 16 to rotate, a lifting rod 31 is fixedly connected to the top of the base 1, and the lower pressure box 3 is slidably connected to the lifting rod 31 through a lifting plate 32, and a first spring 33 is sleeved on the lifting rod 31 below the lifting plate 32, and the pressure roller 4 is arranged below the lower pressure box 3 and is symmetrically arranged from left to right.

[0023] Furthermore, the power mechanism includes a driven gear 21 and a motor 22; a driving gear 23 is symmetrically fixed to the front and rear of the first shaft 15, the driven gear 21 is rotatably connected to the bottom of the driving gear 23 and meshes with the driving gear 23, a first transmission wheel 24 is fixed to the outer side of the driven gear 21, and a second transmission wheel 25 is fixed to the front and rear ends of the second shaft 16, the second transmission wheel 25 and the first transmission wheel 24 are linked by a belt 26, and a first guide rod 27 and a second guide rod 28 are also fixed to the front and rear sides of the base 1, the first guide rod 27 and the second guide rod 28 are used to guide the belt 26 so that the position of the belt 26 is staggered with the V-shaped groove 11, the motor 22 is fixed to the front side of the base 1 through a bracket 29, and the output shaft of the motor 22 is connected to the front end of the first shaft 15 through a coupling 210.

[0024] Furthermore, the pressure roller 4 is rotatably connected between two opposite side plates of the U-shaped frame 41, and a slide bar 42 is symmetrically fixed to the top of the U-shaped frame 41, and the slide bar 42 is slidably connected to the top plate of the lower pressure box 3. A connecting plate 43 is integrally fixed to the top of each slide bar 42, and a second spring 44 is sleeved on the slide bar 42.

[0025] Furthermore, the connecting plate 43 is made of metal, a pair of metal plates 51 are fixedly connected to the top plate of the lower pressure box 3, a control switch 52 is fixedly connected to the left side of the base 1, and also includes an external power supply 53, one pole of the external power supply 53 is electrically connected to one of the metal plates 51, the other pole of the external power supply 53 is electrically connected to one pole of the motor 22 through the control switch 52, and the other pole of the motor 22 is electrically connected to the other metal plate 51.

[0026] Furthermore, a track rod 61 is fixedly connected to the top of the lower pressure box 3, and a track block 62 is slidably connected to the track rod 61. It also includes a lower pressure rod 63, and the right end of the lower pressure rod 63 is hinged to the track block 62. A rotating shaft 64 is fixedly connected between the two lifting rods 31 on the left side. The lower pressure rod 63 is rotatably connected to the rotating shaft 64, and the distance between the left end of the lower pressure rod 63 and the rotating shaft 64 is greater than the distance between the rotating shaft 64 and the right end of the lower pressure rod 63.

[0027] A specific implementation of the utility model is:

[0028] like Figure 3 As shown, in the initial state, under the action of the first spring 33, the lower pressure box 3 is located at the high point, and under the action of the second spring 44, the connecting plate 43 contacts the upper surface of the bottom plate of the lower pressure box 3, placing the pipe body A in the V-shaped groove 11, and the cutting position of the pipe body A is aligned with the cutting blade 17, the bottom of the pipe body A contacts the cutting blade 17 and the conveying rubber roller 18 respectively, and the control switch 52 is closed.

[0029] The left end of the lower pressure rod 63 is lifted, and the lower pressure rod 63 rotates around the rotating shaft 64, so that the right end of the lower pressure rod 63 descends, and the track block 62 slides on the track rod 61 so that the right end of the lower pressure rod 63 can descend smoothly. Since the distance between the left end of the lower pressure rod 63 and the rotating shaft 64 is greater than the distance between the rotating shaft 64 and the right end of the lower pressure rod 63, according to the lever principle, the lower pressure rod 63 can save effort, so that a smaller force can be applied to make the lower pressure box 3 descend.

[0030] The lower pressure box 3 drives the pressure roller 4 to descend. When the pressure roller 4 contacts the upper part of the pipe body A, it remains stationary. When the lower pressure box 3 continues to descend, the slide bar 42 moves up relative to the lower pressure box 3, and the second spring 44 is compressed. The compression reaction force of the second spring 44 acts on the pressure roller 4, so that the pressure roller 4 presses the pipe body A tightly to fix the pipe body A.

[0031] When the slide bar 42 moves upward relative to the lower pressure box 3, the connecting plate 43 is driven to move. When the connecting plate 43 contacts the two metal plates 51, since the connecting plate 43 is made of metal, the two metal plates 51 are electrically connected. Figure 6 As shown, since the control switch 52 is closed, when the two metal plates 51 are electrically connected, the motor 22 works.

[0032] like Figure 4 As shown, the motor 22 drives the first shaft 15, the cutting blade 17, and the driving gear 23 to rotate through the coupling 210, and the driven gear 21 meshing with the driving gear 23 rotates, so that the first transmission wheel 24 rotates, and under the action of the belt 26, the second transmission wheel 25 rotates, so that the second shaft 16 and the conveying rubber roller 18 rotate. Since the mutually meshing driven gear 21 and the driving gear 23 rotate in opposite directions, the cutting blade 17 and the conveying rubber roller 18 rotate in opposite directions.

[0033] like Figure 3 As shown, assuming that the conveying rubber roller 18 rotates clockwise, it drives the pipe body A to rotate counterclockwise through friction, and the cutting blade 17 also rotates counterclockwise. The contact position of the cutting blade 17 and the pipe body A has an opposite tangential speed, which improves the cutting effect.

[0034] During the cutting process, the left end of the pressing rod 63 is always pressed downward so that the pipe body A is always in contact with the cutting blade 17 to ensure smooth cutting. After cutting, the pressing rod 63 is released, and under the action of the first spring 33 and the second spring 44, the pressing box 3 and the pressure roller 4 are reset respectively, and the cut pipe body A is removed.
