Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to a waste discharge device used on a die-cutting machine. Background Art

[0002] The waste discharge device on the die-cutting machine is specially used to handle the waste generated during the die-cutting process, such as buffer tape. After being die-cut into a certain shape, the waste will be wound up with the winding roller. Usually during die-cutting, the waste will be subjected to pulling force as the winding roller moves, causing the waste to wrinkle, which makes it more troublesome to wind it up.

[0003] According to the Chinese patent publication number CN215395344U "A buffer tape die-cutting waste discharge device for a die-cutting machine", it mainly describes the scraping waste discharge processing through the scraping blade on the tool holder. The tool holder can be controlled to flip through the control component, and the scraping blade can be quickly switched to achieve non-stop scraping processing with high waste discharge efficiency. At the same time, a large amount of waste glue is stuck on the scraping blade switched down from the bottom of the tool holder. The shaft motor on the cleaning unit can drive the cleaning blade to move back and forth to clean the waste glue on the scraping blade. The heating rod makes the waste glue on the cleaning blade fall off, and then it is collected through the waste recycling box. In this process, traction will be provided on one side of the waste when the waste is rolled up, so that the waste after die-cutting will be wrinkled, which makes it inconvenient to roll up the waste.

[0004] Therefore, a waste discharge device for a die-cutting machine is proposed to solve the problem that during the process, traction is provided on one side of the waste when the waste is rolled up, thereby causing wrinkles in the waste after die-cutting and making it inconvenient to roll up the waste.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1-3 The waste discharge device shown in the figure is used for the die-cutting machine, including a support frame 1, a pressure wheel 2 and a guide roller 3. A lower die knife is set on the support frame 1, which can cooperate with the upper die knife 10 to realize die cutting. The guide roller 3 is driven by the drive motor to reel up the die-cutting waste. The four sides of the upper end of the support frame 1 are fixedly connected with electric push rods 4, and the electric push rods 4 drive the movable plate 5 to achieve height movement. The output end of the electric push rod 4 is fixedly connected to the movable plate 5. The center of the bottom end of the movable plate 5 is fixedly connected to a card plate 6, and the upper end of the card plate 6 is sleeved. There is a connecting block 7, which is threaded with a positioning rod 8. One end of the positioning rod 8 is in contact with the clamping plate 6. A fixing seat 9 is provided on the bottom side of the connecting block 7. By setting a replaceable fixing seat 9, it can adapt to different degrees of die-cutting. The bottom end of the fixing seat 9 is glued to an upper die knife 10, and the upper end of the fixing seat 9 is fixedly connected to a first screw 11. A fixing sleeve is fixedly connected to the first screw 11. Both sides of the support frame 1 that are away from each other are in contact with stabilizing wheels 18. Different fixing seats 9 can be replaced by setting the first screw 11.

[0018] Among them, a fixing sleeve is provided in the hidden groove 12 , and the hidden groove 12 is located on the connecting block 7 . By providing the hidden groove, the friction between the fixing sleeve and the clamping plate 6 can be reduced.

[0019] Among them, a ball 20 is rotatably embedded on the upper side of the fixing seat 9, and the ball 20 contacts the bottom end of the connecting block 7. The provision of the ball 20 reduces the rotational friction between the connecting block 7 and the fixing seat 9.

[0020] Among them, the stabilizing wheel 18 is rotatably connected to the moving bar 17, the moving bar 17 is threadedly connected to the two sides of the bidirectional screw 16 that are away from each other, the bidirectional screw 16 is rotatably connected between two opposite adjustment blocks 15, the adjustment block 15 is fixedly connected to the upper side of the auxiliary rod 14, the upper side of the auxiliary rod 14 is fixedly connected to the adjustment block 15, the auxiliary rod 14 is movably plugged into the connecting plate 13, and the connecting plate 13 is fixedly connected to both sides of the support frame 1. By setting two stabilizing wheels 18 that can achieve height movement and relative movement, the stability of the movement of the die-cutting material can be improved.

[0021] Among them, the adjusting block 15 is fixedly connected to the fixing bar, the fixing bar is rotatably connected to the upper end of the adjusting rod 19, and the adjusting rod 19 is threadedly connected to the connecting plate 13. By setting the adjusting rod 19, the fixing sleeve and the adjusting block 15 can be rotated to achieve height movement, thereby enabling the stabilizing wheel 18 to achieve height movement, thereby adapting to die-cutting materials of different specifications.

[0022] Working principle: According to the thickness and width of the die-cutting material, the adjusting rod 19 is rotated to move the height of the fixed bar and the adjusting block 15. At this time, the bidirectional screw 16 is adjusted to make the movable bar 17 move relatively, and then the stabilizing wheel 18 stably contacts the die-cutting material. Then the electric push rod 4 is started to retract so that the upper die knife 10 fits the lower die knife on the support frame 1 to achieve die-cutting. Then the drive motor is started to rotate the guide roller 3 to rewind the die-cutting waste. At this time, the stabilizing wheel 18 makes the die-cutting material close to the support frame 1, so that it can provide support when the guide roller 3 provides traction, thereby reducing the wrinkles formed by traction and making the waste discharge and winding more stable.
