Description

Technical Field

[0001] The invention relates to the technical field of die-cutting parts processing, and in particular to a jig for automatically cleaning waste materials after pushing waste materials. Background Art

[0002] Many die-cut products have round holes. During processing, how to remove the waste in the round holes has always been a difficult problem. In the prior art, when batch-producing die-cut products with round holes, it is considered to use a round roller cutter or a hardware die punching method. These two methods can remove 98% or more of the waste from the round holes. However, the above two methods are not universal waste removal methods. For each die-cut product, the waste removal structure needs to be adjusted in a targeted manner, which makes the cost very high.

[0003] In addition, you can also use the knife film for self-priming, but self-priming sometimes leaves an impression on the surface of the round hole, so it cannot be used for products with high requirements. Or you can choose the method of pushing the waste, that is, after the round hole knife die is punched, add a pin to the corresponding position behind the knife die to push the waste into the groove of the lower plate of the knife die, so that the waste is pushed out, but there is a problem that the waste is pushed into the blanking chute, and it is necessary to stop the machine regularly for manual cleaning, and the blanking chute is filled with waste, the waste cannot be discharged cleanly, and the waste runs out and falls on the product, causing dirt and defects. Summary of the invention

[0004] The purpose of the present invention is to provide a jig for automatically cleaning waste after pushing waste in order to overcome at least one of the defects of the above-mentioned prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A jig for automatically cleaning waste after ejecting waste, comprising a top plate and a bottom plate that match each other; the top plate comprises at least one row of round hole knife lines and at least one row of round hole ejecting waste needles parallel to the round hole knife lines; the bottom plate comprises a blanking trough, and blanking holes arranged in the blanking trough and opposite to the positions of the round hole ejecting waste needles; the jig is also provided with a waste discharge plate, waste discharge inclined grooves are arranged at both ends of the waste discharge plate, and the bottom plate is installed between the waste discharge inclined grooves.

[0007] Furthermore, the diameter of the waste needle at the top of the round hole is 0.3-0.6 mm smaller than the punching diameter of the round hole knife line. Preferably, the diameter of the waste needle at the top of the round hole is about 0.5 mm smaller than the punching diameter of the round hole knife line.

[0008] Furthermore, the diameter of the blanking hole is 0.3-0.6 mm larger than the punching diameter of the round hole cutter line. Preferably, the diameter of the blanking hole is about 0.5 mm larger than the punching diameter of the round hole cutter line.

[0009] Furthermore, the height of the blanking groove is 2-4 mm, preferably about 3 mm.

[0010] Furthermore, the inclination angle between the waste discharge chute and the horizontal plane is 15-20 degrees. In this way, when the waste is filled in the material drop chute of the bottom plate, it will fall into the waste discharge chute of the waste discharge plate. The waste discharge chute is inclined, and the waste will fall to the edge and then be collected in the waste chute of the die-cutting machine.

[0011] Furthermore, at least two groups of positioning hole guide columns are provided on both sides of the top plate, and the positioning hole guide columns are located on the circular hole cutter line and the extension line of the straight line where the circular hole cutter line is located.

[0012] Furthermore, guide post holes corresponding to the positions of the guide posts in the positioning holes are provided on both sides of the bottom plate.

[0013] Furthermore, one end of the positioning hole guide post inserted into the guide post hole is tapered.

[0014] Furthermore, a group of positioning hole cutter lines are provided on both sides of the top plate, and the positioning hole cutter lines are located on the extension lines of the straight lines where the positioning hole guide columns on the same side are located.

[0015] Furthermore, the distance between the positioning hole cutter line and the positioning hole guide column is equal to the distance between the positioning hole guide columns on the same side.

[0016] Furthermore, the positioning hole cutter line is located on a side away from the waste needle at the top of the round hole.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) In the jig provided in the present invention, when the waste material is filled in the material drop groove of the bottom plate, it will fall into the waste discharge chute of the waste discharge plate. The waste discharge chute is inclined, and the waste material will fall to the edge and then be collected in the waste chute of the die-cutting machine.

[0019] (2) The jig provided in the present invention does not require manual shutdown to clean up waste materials, and the waste materials will fall into the waste collection trough of the die-cutting machine along the inclined trough. BRIEF DESCRIPTION OF THE DRAWINGS
