DETAILED DESCRIPTION

[0021] The technical scheme of the utility model will be further specifically explained in combination with the drawings through the embodiments.

[0022] In combination with Figure 1 and Figure 2As shown, a cutting machine includes a worktable 1, a guide groove 2 on the worktable 1, a cutting mechanism 3 in the middle of the guide groove 2, and a transmission mechanism 4 at the rear end of the guide groove 2.

[0023] The cutting mechanism 3 includes a housing 19 and a cutting circular blade 5 rotatably connected inside the housing 19. The guide groove 2 has a corresponding clearance groove 6 in the middle, and a connecting seat 7 is provided on the worktable 1 on both sides of the guide groove 2. One end of the housing 19 is rotatably connected to the connecting seat 7 on both sides. A first driving mechanism 8 for driving the cutting circular blade 5 to rotate is also provided on one side of the housing 19. Openings 9 are provided at the front and rear ends of the lower part of the housing 19, and the two openings 9 allow the material to be cut to pass through.

[0024] The transmission mechanism 4 includes two columns 10 and a transmission roller 11 disposed between the two columns 10. A slider 12 is vertically connected to each of the two columns 10. The two ends of the transmission roller 11 are rotatably connected to the two sliders 12. A second driving mechanism 13 for driving the transmission roller 11 to rotate is also provided on the outer side of one of the two sliders 12.

[0025] The working principle of the above structure is as follows: the material to be cut is placed in the guide groove 2. Initially, one end of the material is passed under the cutting mechanism 3 and its end is placed under the transmission roller 11 of the transmission mechanism 4. The transmission roller 11 abuts against the material. When the transmission roller 11 rotates, it will drive the material to move towards the rear end of the guide groove 2. The material is cut when it passes through the self-rotating cutting circular blade 5.

[0026] It should be noted that when the cutting machine is cutting soft materials such as fabric, the cutting mechanism 3 needs to be lifted first. With manual assistance, the material is passed under the cutting mechanism 3 and placed under the transmission roller 11. Then, the cutting mechanism 3 is engaged for automatic cutting. When the cutting mechanism 3 is cutting harder materials such as thin sheet metal, the material only needs to be pushed directly to the rear end of the guide groove 2. Automatic cutting can be achieved when the transmission roller 11 comes into contact with the material.

[0027] The advantages of the above structure are: it can automatically cut materials with only simple preliminary operations; it can adapt to cutting not only soft materials such as cloth, but also relatively hard materials such as thin sheet metal; it has a simple structure and low manufacturing cost; the cutting round blade 5 is placed inside the housing 19, which is safer and more reliable and can avoid safety accidents.

[0028] In another embodiment, such as Figure 2 As shown, a first counterweight 14 is provided on the side of the housing 19 away from the first drive mechanism 8 to balance the center of gravity of the housing 19 and increase the weight of the cutting mechanism 3 to prevent the cutting mechanism 3 from bouncing during the cutting process.

[0029] In another embodiment, combined Figure 1 and Figure 2 As shown, the two columns 10 are respectively provided with corresponding sliding grooves for the sliders 12. The sliders 12 are slidably connected in the corresponding sliding grooves. A spring 15 is also provided between the top of the sliding groove and the slider 12 so that the transmission roller 11 always maintains a downward pressing tendency through the slider 12. A second counterweight 16 is also fixed on the outer side of the other slider 12 to balance the center of gravity of the transmission roller 11 and increase the weight of the transmission roller 11, so as to ensure that the transmission roller 11 and the material make more reliable contact.

[0030] In another embodiment, combined Figure 1 and Figure 2 As shown, a handle 17 is also provided on the top of the housing 19.

[0031] In another embodiment, combined Figure 1 and Figure 2 As shown, the handle 17 is inverted "L" shape, and the grip of the handle 17 is set towards the transmission mechanism 4 so that the center of gravity of the entire cutting mechanism 3 is rearward after being engaged.

[0032] In another embodiment, such as Figure 1 As shown, the outer side of the transmission roller 11 is also provided with an elastic damping layer so that the transmission roller 11 can better transmit the material to be cut.

[0033] In another embodiment, combined Figure 1 and Figure 2 As shown, the front and rear ends of the housing 19 are respectively provided with chamfers.

[0034] In another embodiment, elastic layers 18 are provided on the bottom sides of the housing 19 to reduce the transmission of vibrations when the first drive mechanism 8 is working.

[0035] Specifically, both the first drive mechanism 8 and the second drive mechanism 13 are electric motors.

[0036] In another embodiment, a plurality of limiting blocks are also included, each of which is fixed on both sides of the guide groove 2 to limit the materials of different specifications on both sides, so as to prevent the materials from deviating during the cutting process.
