[0035] The present invention will be described in detail below with reference to the accompanying drawings:

[0036] Embodiment 1

[0037] As Figure 1As shown in the figure, the novel cutting machine of this embodiment includes a feeding mechanism, and the feeding mechanism includes: a first driving gear 25 and a second driving gear 26. The first driving gear 25 and the second driving gear 26 are respectively arranged in the advancing direction of the material. The second driving gear 26 is located in front of the first driving gear 25 in the advancing direction of the material. That is, when the material to be cut is fed, it first passes through the first driving gear 25 and then through the second driving gear 26. The diameter of the second driving gear 26 is smaller than that of the first driving gear 25, and the first driving gear 25 and the second driving gear 26 are arranged in a linked manner.

[0038] This embodiment further includes a fourth driving device 27, a first transmission belt 28 and a second transmission belt 29. As Figure 1 shown, two ends of the first transmission belt 28 are respectively connected to the fourth driving device 27 and the first driving gear 25, and two ends of the second transmission belt 29 are respectively connected to the fourth driving device 27 and the second driving gear 26. Or as Figure 2 shown, two ends of the first transmission belt 28 are respectively connected to the fourth driving device 27 and the first driving gear 25, and two ends of the second transmission belt 29 are respectively connected to the first driving gear 25 and the second driving gear 26.

[0039] This embodiment further includes a first driving shaft 30, a second driving shaft 31, a first pressing shaft 32 and a second pressing shaft 33. The first driving gear 25 is arranged to drive the first driving shaft 30 to rotate, and the second driving gear 26 is arranged to drive the second driving shaft 31 to rotate. The first pressing shaft 32 is pressed above the first driving shaft 30, and the material can pass between the first pressing shaft 32 and the first driving shaft 30; the first pressing shaft 32 and the first driving shaft 30 are arranged to be relatively far away from each other; the second pressing shaft 33 is pressed above the second driving shaft 31, and the material can pass between the second pressing shaft 33 and the second driving shaft 31; the second pressing shaft 33 and the second driving shaft 31 are arranged to be relatively far away from each other; the weight of the second pressing shaft 33 is greater than that of the first pressing shaft 32. In this embodiment, the second pressing shaft 33 is a solid shaft, and the first pressing shaft 32 is a hollow shaft.

[0040] Lifting members 34 are respectively arranged below two ends of the first pressing shaft 32 and the second pressing shaft 33. The lifting members 34 are provided with grooves, and two ends of the first pressing shaft 32 and the second pressing shaft 33 are rotatably arranged in the grooves. The lifting members 34 are driven by a fifth driving device 35. In this way, two ends of the first pressing shaft 32 and the second pressing shaft 33 can be lifted away from the first driving shaft 30 and the second driving shaft 31. The lifting members 34 are arranged to be bendable, which is convenient for the fifth driving device 35 to be arranged on the sides of the first and second pressing shafts 33 instead of directly below the first and second pressing shafts 33. Or, the fifth driving device 35 is arranged above the lifting members 34 to pull the lifting members 34 to drive the lifting members 34.

[0041] The fourth driving device 27 is a motor. When the motor starts, the first transmission belt 28 and the second transmission belt 29 drive, and the first driving gear 25 and the second driving gear 26 rotate synchronously. The first driving gear 25 drives the first driving shaft 30 to rotate, and the second driving gear 26 drives the second driving shaft 31 to rotate. In this way, when the material is laid between the first driving shaft 30 and the first pressing shaft 32, and between the second driving shaft 31 and the second pressing shaft 33, the material is driven to feed by the first driving shaft 30 and the second driving shaft 31.

[0042] The first driving gear 25 and the second driving gear 26 rotate synchronously, and the diameter of the second driving gear 26 is smaller than that of the first driving gear 25. In this way, the rotational speed of the second driving gear 26 is faster than that of the first driving gear 25. In the material feeding direction, the speed of the front end is faster than that of the rear end, and the material is tightened, which is beneficial to the cutting quality of the material. Correspondingly, the second pressing shaft 33 with a larger weight is pressed above the second driving shaft 31 with a faster speed, and the first pressing shaft 32 with a smaller weight is pressed above the first driving shaft 30 with a slower speed. In the material feeding direction, the front end of the material is subjected to greater force, which is beneficial to the feeding of the material, and thus beneficial to better cutting quality when the material is cut.

[0043] As Figure 3 , Figure 4 and Figure 5 shown, the first driving shaft 30 is located behind the main shaft 2 of the longitudinal cutting mechanism 1, and the second driving shaft 31 is located in front of the main shaft 2 of the longitudinal cutting mechanism 1. The front and the rear are also in relation to the material advancing direction. That is, when the material feeds, it passes through the first driving shaft 30, the main shaft 2, and the second driving shaft 31 in sequence. The longitudinal cutting mechanism 1 is used to cut the material along the advancing direction of the material. The rotation of the main shaft 2 of the longitudinal cutting mechanism 1 can drive the cutting knife to cut the material along the advancing direction of the material.

[0044] Embodiment 2

[0045] As Figure 6 shown, this embodiment further includes a feeding mechanism, and the feeding mechanism includes a support positioning member 60 which is rotatably arranged; both ends of the support positioning member 60 are rotatably arranged. The support positioning member 60 is arranged at an interval from the feeding mechanism. Specifically, the support positioning member 60 is arranged at an interval from the first driving shaft 30.

[0046] The material to be cut is first fed, then enters the first driving shaft 30 of the feeding mechanism, is fed through the feeding mechanism, and enters the cutting mechanism 50 for cutting, wherein the cutting mechanism 50 includes a longitudinal cutting mechanism and a transverse cutting mechanism. The longitudinal cutting mechanism and the transverse cutting mechanism can refer to the conventional technology.

[0047] This embodiment further includes a frame 61 and a horizontal bracket 62. The horizontal bracket 62 is arranged on the frame 61. Both ends of the support and positioning member 60 are rotatably arranged on the horizontal bracket 62 respectively. The support and positioning member 60 includes an air shaft. The feeding mechanism further includes a tension roller 63. The air shaft and the tension roller 63 are arranged on the horizontal bracket 62 at intervals. Two support rods 64 are arranged on the horizontal bracket 62. Each support rod 64 is respectively provided with a vertically arranged U-shaped groove 65 for supporting both ends of the air shaft. The opening of the vertically arranged U-shaped groove 65 faces upward. Both ends of the air shaft are rotatably arranged on the vertically arranged U-shaped groove 65 respectively. The air shaft, the tension roller 63 and the first drive shaft 30 are arranged at intervals respectively.

[0048] A cutting mechanism 50 is arranged on the frame 61. The air shaft, the tension roller 63 and the cutting mechanism 50 are arranged in sequence and at intervals respectively. When feeding the material, it passes through the air shaft and the tension roller 63 in sequence, and then enters the first drive shaft 30. The material is arranged in a roll on the air shaft. When feeding, a layer of material is pulled out from the direction of the air shaft, bypasses the tension roller 63, and enters the first drive shaft 30 for feeding and cutting.

[0049] The material is arranged in a roll on the unexpanded air shaft. After the feeding is completed, the air shaft expands and tensions the rolled material, and the axial position of the rolled material on the air shaft will not shift. It achieves a good positioning effect on the material. And due to the tensioning effect of the air shaft, the material is more tightly wound when being fed in a roll, which is beneficial to the cutting of the material.

[0050] Embodiment 3

[0051] As Figure 7 and Figure 8 shown, slightly different from Embodiment 2, this embodiment further includes a frame 61. The frame 61 is provided with a cutting mechanism 50. The support and positioning member 60 includes an air shaft. The air shaft is arranged below the lower part of the frame 61 and below the cutting mechanism 50. Both ends of the air shaft are rotatably arranged on the frame 61 respectively, that is, the air shaft is rotatably arranged; the air shaft is arranged at intervals with the cutting mechanism 50. Specifically, the air shaft is arranged at intervals with the first drive shaft 30. This embodiment provides a different feeding method from Embodiment 2 to adapt to materials of different specifications. The material enters the first drive shaft 30 from the air shaft.

[0052] Embodiment 4

[0053] As Figure 7 and Figure 8 shown, one end of the support and positioning member 60 described in this embodiment is arranged to be movable radially, and the other end of the support and positioning member 60 is arranged to be rotatable radially. The support and positioning member 60 is an air shaft.

[0054] The frame 61 is provided with a support bearing at one end of the support positioning member 60, and a support seat is provided at the other end of the support positioning member 60, and a horizontal U-shaped groove 66 is provided on the support seat; one end of the support positioning member 60 is provided on the support bearing, and the other end is provided in the horizontal U-shaped groove 66. That is, a universal bearing is provided at one end of the air shaft, and the other end is provided in a horizontal U-shaped groove 66. The opening of the horizontal U-shaped groove 66 faces away from the frame 61. When the material is loaded, one end of the air shaft is radially moved out of the horizontal U-shaped groove 66, and the material can be loaded. After the loading is completed, the end of the air shaft is moved into the horizontal U-shaped groove 66.

[0055] The radially rotatable end of the support positioning member 60 is provided with a blocking member, and the blocking member can block the radial rotation of the support positioning member 60. There are multiple blocking members, which are respectively arranged around the universal bearing and are located on the axial outside of the support positioning member 60. In this embodiment, the support positioning member 60, that is, the universal bearing of the inflatable shaft, is arranged in a support frame 40, and one side of the support frame 40 protrudes to form a first blocking member 44. The other blocking members are rods 41, 42, and 43 arranged on the first blocking member 44. The first blocking member 44 and the rods 41, 42, and 43 are connected in pairs to form a frame. When this end of the inflatable shaft rotates radially, if it rotates within a set reasonable range, it will not hit the blocking member. If it rotates beyond the set reasonable range, it will hit the blocking member. In this way, the blocking member can prevent the inflatable shaft from excessive radial rotation.

[0056] The present invention is conducive to keeping the material in a taut state during feeding, which is conducive to cutting. The cutting quality of the present invention is better. The present invention can realize the positioning of the feeding material, prevent the material from being offset during the moving process, and thus avoid affecting the cutting quality of the material. The present invention is simple in structure, practical, and easy to implement.

[0057] The embodiments of the present invention are only used to illustrate the present invention and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutes that can be thought of by those skilled in the art are all within the protection scope of the present invention.
