[0056] like Figure 1-4As shown, the utility model provides a rubber strip cutting device, including a base 1, a cutting roller bracket 12 is provided on the base 1, and a cutting roller 3 is provided on the cutting roller bracket 12. The cutting roller includes: an upper cutting roller 31 and a lower cutting roller 32. The upper cutting roller 31 is provided with a plurality of equally spaced circular blades 311, and the blades 311 are coaxial with the cutting roller. The lower cutting roller 32 is provided with a plurality of knife grooves 321 matching the blades 311. The plurality of blades 311 can be inserted into the corresponding knife grooves 321. Further, a height adjustment groove 121 is provided on the cutting roller bracket 12, and a movable block 16 is provided in the height adjustment groove 121, and the movable block 16 can move up and down along the height adjustment groove 121. Further, the upper cutting roller 31 is connected to the movable block 16. The top of the cutting roller bracket 12 is provided with an adjusting bolt 13 that penetrates the cutting roller bracket 12. The adjusting bolt 13 is threadedly connected to the cutting roller. The bottom of the adjusting bolt 13 is provided with a spring fixing seat 14. The lower end of the spring fixing seat 14 is connected to a spring 15. The lower end of the spring 15 is connected to the movable block 16. A fixing column 161 is provided on the outer side of the movable block 16. The fixing column 161 is provided with an adjusting handle 4. The adjusting handle 4 is used to adjust the height of the movable block 16. Specifically, the adjusting handle 4 includes: a support rod 41 and a push-pull rod 42. Among them, there are two support rods 41, and the two support rods 41 are symmetrically arranged on both sides of the push-pull rod 42 and are perpendicular to the push-pull rod 42. The support rod 41 is provided with a fixing hole 412 that matches the fixing column 161. The cutting roller bracket 12 is provided with a cylindrical pillar 122. The pillar 122 and the fixing column 161 are located in the same plane. The push-pull rod 42 is provided with a long strip sliding groove 411 with a width the same as the diameter of the pillar 122, and the pillar 122 is located in the sliding groove 411. In the scheme, the support rod 41 and the fixed column 161 form a lever structure with the support column 122 as a fulcrum, and the movable block 16 is lifted by pulling one end of the support rod 41 through the push-pull rod 42.

[0057] During use, the user can precisely adjust the height of the upper cutting roller 31 by rotating the adjusting bolt 13, so as to meet the needs of cutting rubber sheets of different thicknesses. In addition, the upper cutting roller 31 in the device is connected with a spring.
