Description

Technical Field

[0001] This utility model relates to the technical field of tire cutting equipment, and more specifically, it relates to a tire pretreatment cutting device. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. The recycling and reuse of waste tires first involves disassembling the waste tires, and then grinding them into powder. An important step in the disassembly process is cutting the tires into strips, which improves the efficiency of the subsequent disassembly of waste tires.

[0003] Existing tire strip cutting devices are not convenient for collecting the cut tire strips when cutting tires. The cut tire strips usually fall directly to the ground. Because the cut tire strips are relatively long, the area of ​​tire strips scattered on the ground is large. This large area of ​​tire strips scattered on the ground affects the walking of workers and makes them more likely to trip and cause safety accidents. In addition, it is not easy to accurately control the width of the tire strips, resulting in tire strips of varying widths. Utility Model Content

[0029] Please see Figures 1-5A tire pretreatment strip cutting device includes a workbench 1 and two cutting discs 2. A fixed base 3 is fixedly connected to the top of the workbench 1. Two rotating shafts 4 are rotatably connected to the fixed base 3. The two cutting discs 2 are respectively mounted on the two rotating shafts 4. Gears 5 are installed on both rotating shafts 4 and mesh with each other. A reducer 6 is installed on the workbench 1. The output shaft of the reducer 6 is fixedly connected to the rotating shaft 4 located on the lower side. A motor 7 that drives the reducer 6 is installed on the reducer 6. A positioning plate 8 is connected to the fixed base 3 through an adjusting assembly. A horizontal plate 9 is fixedly connected to the side end of the fixed base 3. A reinforcing plate 22 is fixedly connected to the bottom end of the horizontal plate 9. The side end of the reinforcing plate 22 is fixedly connected to the side end of the fixed base 3, raising the connection between the horizontal plate 9 and the fixed base 3. For stability, a triangular seat 10 is fixedly connected to the side end of the horizontal plate 9 at the position corresponding to the two cutting discs 2. A bevel 24 is provided at the side end of the positioning plate 8 at the position corresponding to the triangular seat 10, gradually increasing the gap between the positioning plate 8 and the triangular seat 10 to facilitate tire strip transportation. A guide trough 11 is fixedly connected to the side end of the horizontal plate 9. A support seat 23 is fixedly connected to the bottom end of the guide trough 11. The bottom end of the support seat 23 is fixedly connected to the top end of the workbench 1 to facilitate stable support for the guide trough 11. A collection box 12 is placed below the guide trough 11. A support bar 13 is fixedly connected to the side end of the positioning plate 8. The height of the top surface of the support bar 13 is higher than the height of the top surface of the horizontal plate 9, and the height of the top surface of the support bar 13 is lower than the height of the cutting points of the two cutting discs 2.

[0030] Specifically, the motor 7 drives the reducer 6 to rotate, which in turn drives the lower shaft 4 to rotate. Through the meshing of two gears 5, the two shafts 4 rotate, and the two shafts 4 drive the two cutting discs 2 to rotate respectively. The tire to be cut into strips is placed between the two cutting discs 2, and the tire is cut into strips by the cooperation of the two cutting discs 2. The tire strips cut by the two cutting discs 2 slide through the support bar 13 to the triangular seat 10 and the positioning plate 8 on the horizontal plate 9. The tire strips are inserted into the guide trough 11 from between the triangular seat 10 and the positioning plate 8, and fall into the collection box 12 through the guide trough 11. The collection box 12 facilitates the collection of the cut tire strips, preventing the tire strips from falling on the ground, avoiding obstruction of workers' walking and work, and preventing workers from tripping and causing safety accidents.

[0031] Please see Figure 1 , Figure 2 and Figure 4The adjustment assembly includes two adjustment plates 14. A fixed base 3 has two sliding grooves 15, with each adjustment plate 14 slidingly engaging with one of the two sliding grooves 15. The side ends of both adjustment plates 14 are fixedly connected to the side ends of a positioning plate 8. A fixed plate 16 is fixedly connected to the other end of each adjustment plate 14. A screw 17 is threaded onto the fixed plate 16 and rotatably connected to the fixed base 3. A handle 18 is fixedly connected to the side end of the screw 17 for easy rotation. A reference plate 19 is fixedly connected to the side end of the positioning plate 8, with scale lines 20 on it. A fixing screw 21, which engages with the adjustment plates 14, is threaded onto the side end of the fixed base 3. Tightening the fixing screw 21 causes its side end to abut against the side end of the adjustment plate 14, facilitating the fixing of the adjustment plates 14 and the positioning plate 8.

[0032] Specifically, by rotating the screw 17, the fixed plate 16, the two adjusting plates 14, and the positioning plate 8 are moved, thereby adjusting the position of the positioning plate 8 and the gap between the positioning plate 8 and the two cutting discs 2. This facilitates the corresponding adjustment of the width of the tire strip and ensures the accuracy of the tire strip width. When adjusting the positioning plate 8, the scale value on the scale line 20 on the reference plate 19 is observed at the end face of the fixed seat 3 near the cutting disc 2. This scale value is the distance between the side end of the positioning plate 8 and the two cutting discs 2, thus facilitating accurate and rapid adjustment of the position of the positioning plate 8.

[0033] In summary, when using the overall equipment:

[0034] Rotating screw 17 moves the fixed plate 16, the two adjusting plates 14, and the positioning plate 8, adjusting the position of the positioning plate 8. The gap between the positioning plate 8 and the two cutting discs 2 is adjusted according to the required width of the tire strip, so that the end face of the fixed seat 3 near the cutting disc 2 is positioned at the corresponding scale value on the scale line 20 of the reference plate 19. At this point, the distance between the positioning plate 8 and the two cutting discs 2 is the required width of the tire strip. Then, the motor 7 drives the reducer 6 to rotate, and the reducer 6 drives the rotating shaft 4 located on the lower side. The rotation, through the meshing of two gears 5, causes two rotating shafts 4 to rotate, and the two rotating shafts 4 respectively drive two cutting discs 2 to rotate. The tire to be cut into strips is placed between the two cutting discs 2, and one end of the tire contacts the side end of the positioning plate 8. The tire is cut into strips through the cooperation of the two cutting discs 2. The cut tire strips are moved to the middle of the triangular seat 10 and the positioning plate 8 through the support bar 13, and inserted into the inside of the guide trough 11. The tire strips are transported to the inside of the collection box 12 through the guide trough 11, and the tire strips are collected through the collection box 12.
