[0003] The ABS plastic sheet is an engineering plastic sheet made of acrylonitrile-butadiene-styrene (ABS) material. During the production process of the ABS plastic sheet, it needs to be cut according to size requirements. Currently, most cutting operations require manual measurement of the length of the ABS plastic sheet and then cutting it after determining the length. The operation is relatively cumbersome, and at the same time, the processing efficiency is low. Therefore, we propose a cutting device for ABS plastic sheets to solve the above problems. Summary of the Utility Model

The rotating rod is rotatably connected to the adjusting bolt. The push rod and the cushion block are at the same height.

[0010] In a preferred embodiment of the present invention, the conveying mechanism is two cooperating conveying rollers driven by a motor. The conveying rollers convey the plate so that it moves between the upper cutting seat and the lower cutting seat.

[0011] In a preferred embodiment of the present invention, guide columns are fixed at both ends of the mounting seat. The guide columns are inserted into and slidably connected to the support seat.

[0014] In a preferred embodiment of the present invention, the limiting plate is located on the conveying path of the plate, so that the plate can push the limiting plate during the moving process, thereby driving the rotating rod to rotate.

[0015] The beneficial effects of the present invention are:

The directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0022] As Figures 1-3An ABS plastic sheet cutting device shown in the figure includes a base 1. A conveying mechanism, a shearing mechanism, and a metering mechanism for conveying the ABS plastic sheet are arranged on the base 1. The shearing mechanism is located between the conveying mechanism and the metering mechanism. Among them, the shearing mechanism includes a lower cutting seat 3 fixed on the base 1 and support seats 4 on both sides of the lower cutting seat 3. An installation seat 6 is arranged above the lower cutting seat 3. An upper cutting seat 7 adapted to the lower cutting seat 3 is fixed on the installation seat 6. And compression springs 5 are fixed between both ends of the installation seat 6 and the support seats 4 on both sides. Guide columns are fixed at both ends of the installation seat 6. The guide columns are inserted into the support seats 4 and are slidably connected to the support seats 4. The compression springs 5 are sleeved on the guide columns. The stability of the installation seat 6 when pressing down is improved through the guide columns, so that the upper cutting seat 7 and the lower cutting seat 3 cooperate to cut the sheet, and after cutting, it is reset by the compression springs 5;

[0023] At the same time, the shearing mechanism also includes a side plate 8 vertically fixed on the base 1. A driving motor 9 is installed at the upper end of the side plate 8. A first connecting rod 10 is fixed on the output shaft of the driving motor 9. The other end of the first connecting rod 10 is rotatably installed with a second connecting rod 11. The bottom end of the second connecting rod 11 is rotatably installed with a pressing seat 12. The pressing seat 12 is located directly above the installation seat 6, and the pressing seat 12 is slidably connected to the side plate 8. The operation of the driving motor 9 drives the pressing seat 12 to reciprocate up and down directly above the installation seat 6;

[0024] Moreover, a support column 21 is arranged on one side of the side plate 8 close to the metering mechanism. The support column 21 is fixed on the base 1. A rotating sleeve 22 is sleeved on the upper end of the support column 21. The rotating sleeve 22 is slidably connected to the support column 21. And a torsion spring 24 is arranged between the rotating sleeve 22 and the support column 21. And a cushion block 23 is fixed on one side of the rotating sleeve 22. The rotating sleeve 22 can rotate and slide on the support column 21. After rotating and sliding, it is reset by the torsion spring 24;

[0025] It should be noted that the cushion block 23 is located on one side of the installation seat 6, and the bottom surface of the cushion block 23 is flush with the upper surface of the installation seat 6, so that the cushion block 23 is located on the upper surface of the installation seat 6 after rotation. Furthermore, the installation seat 6 can be pressed by the pressing seat 12. Under normal conditions, the pressing seat 12 cannot contact the installation seat 6 during reciprocating up and down movement. When the cushion block 23 rotates to above the installation seat 6, the pressing seat 12 presses the cushion block 23 downward. At this time, the cushion block 23 pushes the installation seat 6 to descend, and the upper cutting seat 7 and the lower cutting seat 3 cooperate to cut the sheet;

[0026] Among them, the metering mechanism includes a bracket 13 fixed on the base 1. A slide rail 14 is fixed to the upper end of the bracket 13. A push rod 15 is slidably installed at the upper end of the slide rail 14. The push rod 15 slides in the left-right direction, and a slider 16 with a locking mechanism is installed on the slide rail 14. The locking mechanism is a bolt, and the slider 16 can be fixed by tightening the bolt. A rotating rod 17 is provided on the slider 16. The middle of the rotating rod 17 is rotatably connected to the slider 16, and a limiting plate 18 is fixed to the bottom end of the rotating rod 17. The limiting plate 18 is located on the conveying path of the plate, so that the plate can push the limiting plate 18 during movement, thereby driving the rotating rod 17 to rotate. The upper end of the rotating rod 17 is installed on the push rod 15 through an adjusting bolt 19. The rotating rod 17 is rotatably connected to the adjusting bolt 19. A plurality of adjusting holes 20 are formed in the push rod 15. The plurality of adjusting holes 20 are linearly arranged. The adjusting bolt 19 is inserted into the adjusting hole 20. By adjusting the position of the adjusting bolt 19, after adjusting the position of the slider 16, the position of the upper end of the rotating rod 17 can be synchronously adjusted, which is convenient for better pushing the spacer block 23. The push rod 15 and the spacer block 23 are at the same height. When the rotating rod 17 rotates, it drives the push rod 15 to move towards the shearing mechanism, and the spacer block 23 is pushed to rotate by the push rod 15.

[0027] Secondly, the conveying mechanism is two cooperating conveying rollers 2. The conveying rollers 2 are driven by a motor. The plate is conveyed by the conveying rollers 2 so that it moves between the upper cutting seat 7 and the lower cutting seat 3.

[0028] In this embodiment, the position of the limiting plate 18 is adjusted according to the length of the ABS plastic plate to be cut. At the same time, the position of the rotating rod 17 and the adjusting bolt 19 above it is adjusted. After adjustment, the push rod 15 contacts the side wall of the spacer block 23 in the natural state, and the driving motor 9 is turned on. The driving motor 9 drives the pressing seat 12 to reciprocate up and down directly above the mounting seat 6.

[0029] The ABS plastic plate is conveyed by the two conveying rollers 2 so that it passes between the upper cutting seat 7 and the lower cutting seat 3 and continues to move to push the limiting plate 18. After the ABS plastic plate pushes the limiting plate 18, the rotating rod 17 rotates on the slider 16. At the same time, the upper end of the rotating rod 17 pushes the push rod 15 to move. The spacer block 23 is pushed by the push rod 15 to rotate to the upper end of the mounting seat 6. At this time, the pressing seat 12 presses the spacer block 23, and the spacer block 23 then pushes the mounting seat 6 to descend, so that the upper cutting seat 7 and the lower cutting seat 3 cooperate to cut the plate. After cutting, the corresponding components are driven to reset by the compression spring 5 and the torsion spring 24, and then the next cutting is performed.
