[0016] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0017] Embodiment 1:

[0018] like Figure 1-Figure 5 As shown, the utility model discloses a conveyor belt cutting device, including a base 1 and a reduction motor 6, four tires 2 are arranged on the base 1, a connecting frame 3 is arranged on the base 1, a first mounting frame 4 is arranged at the upper end of the connecting frame 3, a second mounting frame 5 is arranged at the lower end of the connecting frame 3, the reduction motor 6 is installed on the first mounting frame 4, a torque multiplier 7 is arranged at the output end of the reduction motor 6, a driving shaft 14 is connected to the output end of the torque multiplier 7, the driving shaft 14 is horizontally rotatably connected to the second mounting frame 5, two active blades 8 are arranged on the driving shaft 14 at intervals, the active blade 8 is a circular structure, a driven shaft 15 is horizontally rotatably arranged on the second mounting frame 5, two driven blades 9 are arranged on the driven shaft 15 at intervals, the driven blade 9 is a circular structure, the active blade 8 corresponds to the driven blade 9 one by one and fits each other.

[0019] The reduction motor 6 and the torque multiplier 7 are existing commercial products, and their specific structures are not described in detail. The base 1 adopts a frame structure, and its overall height is relatively low. Four tires 2 are arranged on the base 1, and the axial directions of the four tires 2 are parallel to the driving shaft 14 and the driven shaft 15. In actual work, the reduction motor 6 transmits power to the driving shaft 14 through the torque multiplier 7, and the driving shaft 14 drives the driving blade 8 to rotate. The conveyor belt to be cut is pushed between the driving blade 8 and the driven blade 9. The driving blade 8 squeezes the conveyor belt inward when rotating, and the driven blade 9 also rotates to achieve the cutting of the conveyor belt. During the cutting process, due to the rotating cutting of the driving blade 8 and the driven blade 9, the entire cutting device can be driven to move forward to achieve the forward cutting of the conveyor belt. Since the gap between the first mounting frame 4 and the second mounting frame 5 is fixed, as long as the thickness of the conveyor belt is less than the gap, it can be cut. Moreover, since the gap between the active shaft 14 and the driven shaft 15 is fixed, the ends of the active blade 8 and the driven blade 9 are in close contact, so thicker conveyor belts and harder conveyor belts can be cut. In conjunction with the torque multiplier 7, the torque of the active blade 8 can be increased to achieve cutting of steel wire core conveyor belts, etc., and the cutting process is stable and reliable.

[0020] The connecting frame 3 may adopt an I-shaped structure to enhance the firmness of the installation.

[0021] Normally, the spacing between the active blades 8 is 30 mm. Of course, other values ​​can also be selected. The larger the value, the more conveyor belt width is cut during the conveyor belt cutting process, which will cause corresponding waste.

[0022] In order to allow the conveyor belt to move forward smoothly during the cutting process, the width of the connecting frame 3 between the first mounting frame 4 and the second mounting frame 5 is smaller than the spacing between the active blades 8 and the spacing between the driven blades 9. During normal cutting, the active blade 8 cooperates with the driven blade 9 to cut the conveyor belt. During the cutting process, the device moves forward, and the edge of the conveyor belt moves backward after cutting. The width of the connecting frame 3 is smaller than the spacing between the active blades 8, so the edge of the conveyor belt will not interfere with the connecting frame 3, and the conveyor belt cut between the active blades 8 will be discharged downward. The entire cutting process can be stably implemented without interference, and is safe and reliable.

[0023] The active blade 8 is a toothed blade, and the driven blade 9 is a disc blade. The toothed blade can effectively increase the grip between it and the conveyor belt, so that the device can move forward during the cutting process, continuously cut the conveyor belt, reduce the manual thrust requirements on the device, and make the operation easier.

[0024] Connecting plates 10 are provided on both sides of the second mounting frame 5, and the ends of the connecting plates 10 extend to the front between the active blade 8 and the driven blade 9, and guide rollers 11 are provided at the ends of the connecting plates 10. Since the conveyor belt is generally on the ground surface during cutting, and the active blade 8 and the driven blade 9 are both located above the base 1, there is a gap between the conveyor belt and the ground. In order to allow the conveyor belt to maintain a suitable angle to enter between the active blade 8 and the driven blade 9, guide rollers 11 are provided, which can be lifted up before the conveyor belt enters the cutting process to maintain a suitable position for cutting, thereby ensuring that the active blade 8 and the driven blade 9 cut more stably and reliably.

[0025] The connecting plate 10 is fixedly connected to the second mounting frame 5 by bolts, and a positioning hole 12 is provided on the second mounting frame 5 at the edge of the bolt. There are a number of positioning holes 12 in a circular array on the connecting plate 10 at the edge of the bolt. The positioning hole 12 on the second mounting frame 5 corresponds to one of the positioning holes 12 on the connecting plate 10, and is positioned by a positioning pin to adjust the position of the guide roller 11. Due to the different thicknesses of the conveyor belt, the pressure acting on the driven blade 9 is different. In order to ensure that the pressure acting on the driven blade 9 is not too large, different positioning holes 12 are used to adjust the position of the guide roller 11, thereby changing the contact range between the conveyor belt and the driven blade 9, changing the pressure, so that the active blade 8 and the driven blade 9 can stably cut the conveyor belt.

[0026] A support handle 13 is provided on the first mounting frame 4. The design of the support handle 13 can better operate the above device and the operation process is also safer.
