[0015] This embodiment discloses a cutting device for cutting rubber strips of different widths, such as... Figure 1-6 As shown, the workbench includes a worktable 1. Vertical plates 19 are symmetrically fixedly arranged in the width direction of the workbench 1. A horizontal plate 2 is fixedly connected to the upper end of the vertical plate 19. Two sets of positioning rods 9 are symmetrically fixedly arranged on the lower side of the horizontal plate 2. An adjusting component is slidably arranged on the positioning rods 9. Multiple cutting wheels 11 are installed on the lower side of the adjusting component. A lifting component is arranged on the upper part of the workbench 1 for adjusting the distance between the rubber sheet and the cutting wheels 11. According to the width of the rubber strip being cut, the adjusting component is adjusted to adjust the multiple cutting wheels 11 to a suitable adjacent spacing.

[0016] The adjusting component includes a rotating shaft 7 rotatably mounted to the two vertical plates 19. The rotating shaft 7 has two sets of symmetrical spreading grooves 8, each set of which is different. Each spreading groove 8 has a ball bearing 13 slidably mounted inside it. Each ball bearing 13 has an equidistant plate 5 fixedly connected to its lower side. Each equidistant plate 5 is inserted into a positioning rod 9 and moves freely along the length of the positioning rod 9. The cutting wheel 11 is detachably mounted to the lower side of the equidistant plate 5. By rotating the rotating shaft 7, the ball bearings 13 slide relative to each other in the corresponding spreading grooves 8, thereby driving the equidistant plate 5 to move. This allows multiple equidistant plates 5 to move simultaneously at the same distance. The multiple equidistant plates 5 adjust the multiple cutting wheels 11 to a suitable and identical spacing, facilitating the cutting of the rubber sheet into multiple batches of rubber strips of different widths.

[0017] Each cutting wheel 11 has a short shaft 10 fixedly connected to its middle. Each short shaft 10 has a mounting plate 14 rotatably mounted on one side. The mounting plate 14 is detachably connected to the equidistant plate 5. Each short shaft 10 has a spline groove, and a spline rod 12 is inserted into each spline groove. One side of the spline rod 12 is rotatably mounted to the vertical plate 19 and connected to a power shaft through a bevel gear set. A power motor 17 is connected to the upper side of the power shaft. The power motor 17 is fixedly mounted to the horizontal plate 2. The other side of the spline rod 12 is mounted to one side of the vertical plate 19 through a bearing seat. When the power motor 17 is turned on, the power motor 17 drives the spline rod 12 to rotate through the bevel gear set. The rotation of the spline rod 12 simultaneously drives the multiple cutting wheels 11 to rotate, thereby facilitating the cutting of the rubber sheet into rubber strips.

[0018] A worm gear is fixedly installed at one end of the rotating shaft 7. The worm gear is meshed with a worm. The worm is rotatably mounted with the horizontal plate 2. A handwheel 6 is fixedly installed on the upper side of the worm. By rotating the handwheel 6, the handwheel 6 drives the worm to rotate, the worm drives the worm gear to rotate, and the worm gear drives the transmission shaft to rotate.

[0019] The equidistant plate 5 has a side plate on its lower side, and a side groove 15 is opened on the mounting groove. The side plate is inserted into the side groove 15. Multiple insertion holes are opened on the side plate. The side plate is connected to the equidistant plate 5 by locking bolts.

[0020] The lifting component includes ear plates that are inserted into two vertical plates 19. A lifting plate 3 is fixedly installed on the inner side of the two ear plates. The lifting plate 3 can move freely up and down along the vertical plates. A plurality of evenly distributed limiting rods 4 are fixedly installed on the lower side of the lifting plate 3. The limiting rods 4 are inserted into the worktable 1. An electric cylinder 16 is fixedly installed on the lower side of the worktable 1. The output end of the electric cylinder 16 is connected to the lower side of the lifting plate 3. By activating the electric cylinder 16, the output end of the electric cylinder 16 drives the lifting plate 3 to move freely up and down.

[0021] A movable plate 18 is inserted into the middle of the lifting plate 3, and the movable plate 18 can move freely along the length of the lifting plate 3.

[0022] When using this utility model, the adjusting component is adjusted according to the width of the cut rubber strip to adjust the adjacent spacing of multiple cutting wheels 11 appropriately. The rubber plate is placed on the lifting plate 3. After adjusting the lifting component to adjust the rubber plate to a suitable height from the cutting wheels 11, the power motor 17 is turned on to make multiple cutting wheels 11 rotate simultaneously. By moving the position of the moving plate 18, it is convenient to cut the rubber plate into multiple rubber strips at equal intervals.
