[0008] When it is necessary to cut the rubber into pieces of different widths, the adjustment mechanism is started, and the multiple circular knives are driven to move at the same time, so as to adjust the spacing between the multiple circular knives. After adjusting the spacing between the multiple circular knives, the multiple circular knives are fixed by the adjustment mechanism, and then the position of the auxiliary knife is adjusted so that the auxiliary knife and the circular knife are abutted against each other, thereby facilitating the cutting of the rubber. The auxiliary knife is then fixed in the required position, and the drive assembly is started to drive the cutting auxiliary roller to rotate clockwise, and the cutting roller is driven to rotate counterclockwise, and one end of the rubber is placed between the cutting roller and the cutting auxiliary roller, so that the rubber can be cut.

DETAILED DESCRIPTION

[0027] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] The following references Figures 1 to 3 The present utility model will be described.

[0029] A rubber slitting machine includes a body 1, and a slitting auxiliary roller 2 and a slitting roller 3 are rotatably connected to the side wall of the body 1. The slitting roller 3 is located directly above the slitting auxiliary roller 2. The side wall of the slitting auxiliary roller 2 is provided with multiple auxiliary knives 4 with adjustable positions, and the side wall of the slitting roller 3 is provided with multiple circular knives 5. The multiple circular knives 5 are arranged in a one-to-one correspondence with the multiple auxiliary knives 4. An adjustment mechanism is provided in the slitting roller 3, and a drive component is provided on the side wall of the body 1.

[0030] When it is necessary to cut the rubber into pieces of different widths, the adjustment mechanism is started, and the multiple circular knives 5 are driven to move at the same time, so as to adjust the spacing between the multiple circular knives 5. After adjusting the spacing between the multiple circular knives 5, the multiple circular knives 5 are fixed by the adjustment mechanism, and then the position of the auxiliary knife 4 is adjusted so that the auxiliary knife 4 and the circular knife 5 are abutted against each other, thereby facilitating the cutting of the rubber. The auxiliary knife 4 is then fixed in the required position, and the driving component is started to drive the cutting auxiliary roller 2 to rotate clockwise, and drive the cutting roller 3 to rotate counterclockwise, and place one end of the rubber between the cutting roller 3 and the cutting auxiliary roller 2, so that the rubber can be cut.

[0031] By providing an adjustment mechanism, the spacing between multiple circular knives 5 can be adjusted and multiple circular knives 5 can be fixed, solving the problem in the prior art that workers need to adjust and fix multiple cutters one by one, thereby improving efficiency and being more convenient.

[0032] The position-adjustable auxiliary knife 4 includes a first positioning groove 201 formed on the side wall of the slitting auxiliary roller 2, and a first positioning block 6 that cooperates with the first positioning groove 201 is fixed on the inner wall of the auxiliary knife 4. A first screw 7 is screwed on the side wall of the auxiliary knife 4, and the first screw 7 passes through the protruding end of the auxiliary knife 4 and presses against the side wall of the slitting auxiliary roller 2.

[0033] When the position of the auxiliary knife 4 needs to be adjusted, turn the first screw 7 so that the end of the first screw 7 is disengaged from the slitting auxiliary roller 2, so that the auxiliary knife 4 can move. After driving the auxiliary knife 4 to rest against the side wall of the circular knife 5, turn the first screw 7 so that the end of the first screw 7 is pressed against the side wall of the slitting auxiliary roller 2, so that the auxiliary knife 4 is fixed in the desired position.

[0034] The adjusting mechanism includes an adjusting component and a fixing component. The adjusting component includes a second positioning groove 301 formed on the side wall of the slitting roller 3, and a second positioning block 8 that cooperates with the second positioning groove 301 is fixed on the inner wall of the circular knife 5. Multiple circular knives 5 are inserted into the side wall of the slitting roller 3, one of which is fixed in the middle of the slitting roller 3, and the other multiple circular knives 5 are symmetrically arranged on both sides of the circular knife 5. The inner wall of the circular knife 5 is rotatably connected with a first gear 9 and a second gear 10. The first gear 9 and the second gear 10 are fixed to each other. The first gear 9 and the second gear 10 have the same module, and the gear ratio of the first gear 9 to the second gear 10 is 1:2. A first rack 11 that meshes with the first gear 9 is fixed on the inner walls of the two circular knives 5 on both sides of the circular knife 5. In addition, a second rack 12 that meshes with the second gear 10 is fixed on the inner walls of the two circular knives 5 on both sides of the circular knife 5. The fixing component is arranged on the side wall of one of the circular knives 5.

[0035] When it is necessary to adjust the spacing between multiple circular knives 5, one of the circular knives 5 is driven to move, thereby driving the first rack 11 to move, the movement of the first rack 11 drives the first gear 9 to rotate, the rotation of the first gear 9 drives the other first rack 11 to move, thereby driving another circular knife 5 to move, and at the same time, the first gear 9 rotates to drive the second gear 10 to rotate, and the rotation of the second gear 10 simultaneously drives the two second racks 12 to move, thereby driving the other two circular knives 5 to move. Since the first gear 9 and the second gear 10 have the same module and the gear ratio is 1:2, when the first gear 9 rotates to drive the two first racks 11 to move one unit, the second gear 10 rotates to drive the two second racks 12 to move two units, so that the spacing between multiple circular knives 5 can be adjusted equidistantly. After adjusting the spacing between multiple circular knives 5, one of the circular knives 5 is fixed by the fixing component, so that multiple circular knives 5 can be fixed in the desired position at the same time.

[0036] The fixing assembly includes a second screw 13 screwed on the side wall of one of the circular knives 5 . The second screw 13 passes through the protruding end of the circular knife 5 and presses against the side wall of the slitting roller 3 .

[0037] When the circular knife 5 needs to be fixed, the second screw 13 is rotated so that the second screw 13 passes through the protruding end of the circular knife 5 and presses against the side wall of the slitting roller 3, thereby fixing the circular knife 5.

[0038] The driving assembly includes a motor 14 fixed to the upper end of the machine body 1, and a third gear 15 is fixed to the end of each of the slitting roller 3 and the slitting auxiliary roller 2. The two third gears 15 are engaged with each other, and the output end of the motor 14 is fixed to the side wall of one of the third gears 15.

[0039] When the rubber needs to be slit, the motor 14 is started to drive the third gear 15 to rotate, and at the same time drives the other third gear 15 to rotate, thereby driving the slitting auxiliary roller 2 to rotate clockwise and the slitting roller 3 to rotate counterclockwise, placing one end of the rubber between the slitting roller 3 and the slitting auxiliary roller 2, so that the rubber can be slit.

[0040] A feeding plate 16 and a discharging plate 17 are fixed to the side walls of the machine body 1 .

[0041] It is convenient to cut the rubber and collect the cut rubber.

[0042] Working principle:

[0043] When it is necessary to cut the rubber into different widths, one of the circular knives 5 is driven to move, thereby driving the first rack 11 to move, the movement of the first rack 11 drives the first gear 9 to rotate, the rotation of the first gear 9 drives the other first rack 11 to move, thereby driving another circular knife 5 to move, and at the same time, the rotation of the first gear 9 drives the second gear 10 to rotate, and the rotation of the second gear 10 simultaneously drives the two second racks 12 to move, thereby driving the other two circular knives 5 to move. Since the first gear 9 and the second gear 10 have the same module and the gear ratio is 1:2, when the first gear 9 rotates to drive the two first racks 11 to move one unit, the second gear 10 rotates to drive the two second racks 12 to move two units, so that the spacing between multiple circular knives 5 can be adjusted equidistantly. After adjusting the spacing between multiple circular knives 5, one of the circular knives 5 is fixed by the fixing assembly, so that multiple circular knives 5 can be fixed in the desired position at the same time, and then the first screw 7 is rotated to disengage the end of the first screw 7 from the slitting auxiliary roller 2, so that the auxiliary knife 4 can move, and after driving the auxiliary knife 4 to rest against the side wall of the circular knife 5, the first screw 7 is rotated to press the end of the first screw 7 against the side wall of the slitting auxiliary roller 2, thereby fixing the auxiliary knife 4 in the desired position, thereby facilitating the slitting of the rubber, and starting the motor 14 to drive the third gear 15 to rotate, and at the same time drive the other third gear 15 to rotate, thereby driving the slitting auxiliary roller 2 to rotate clockwise, and the slitting roller 3 to rotate counterclockwise, placing one end of the rubber between the slitting roller 3 and the slitting auxiliary roller 2, so that the rubber can be slid.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications based on the above assumptions should also be regarded as within the scope of protection of the present invention.
