Device for completely removing small-hole waste

Technical Field

The utility model belongs to the technical field of the cross cutting is wasted discharge, especially, relate to a complete remove device of aperture waste material.

Background

The die cutting is a cutting process of later processing, and the die cutting process can utilize a pre-manufactured die cutting die to roll and cut paper products or films and the like into pre-designed patterns under the action of pressure.

When die-cut three-layer membrane aperture, need to be to getting rid of the aperture waste material, prior art adopts and inhales the waste hole and gives up, utilizes the waste material after the absorption passageway adsorbs die-cut, nevertheless because the product has three-layer membrane, and thickness is great, has about 20% aperture waste material can't be adsorbed, for solving above-mentioned technical problem, provides a aperture waste material remove device completely.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome current defect, provide a complete remove device of aperture waste material, realize that the limit inhales the slitter edge top useless, guarantee that the interior waste material of aperture is whole to be arranged totally.

In order to realize the purpose, the utility model adopts the following technical scheme: the utility model provides a small hole waste material remove device completely, includes cutting die and sets up the backing plate in the cutting die below, it inhales useless passageway to be provided with the several on the cutting die, the cutting die is provided with the thimble that the several is used for ejecting waste material in next step-by-step distance department, the several inhale the arrangement and the several of useless passageway the arrangement of thimble is the same, the cutting die lower surface corresponds every and inhales useless passageway department and is provided with hollow drift, seted up on the backing plate with the corresponding useless passageway of wasting discharge of thimble.

Compared with the prior art, the utility model discloses realize following beneficial effect:

1. the utility model arranges a hollow punch at the position of the lower surface of the cutting die corresponding to each waste absorbing channel, and after the cutting die moves downwards, the waste in the small hole after die cutting is pressed downwards to completely separate the waste from the product, thereby being beneficial to the absorption of the waste by the subsequent absorption channel and improving the absorption efficiency of the absorption channel;

2. through set up several adsorption channel and several thimble that is used for ejecting waste material on the cutting die, distance between the two is a marching distance, realizes that the limit is inhaled the slitter edge and is pushed up useless, and every aperture of product all passes through twice and gives up useless, once for adsorbing and give up useless, gives up useless for the thimble in addition, guarantees that the interior waste material of aperture is whole to be discharged totally.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples

Referring to fig. 1 to 5, a device for completely removing small hole waste includes a cutting die 10 and a backing plate 20 disposed opposite to the cutting die 10, the cutting die 10 is provided with a plurality of waste suction channels 11, the cutting die 10 is provided with a plurality of ejector pins 12 for ejecting waste at a next step distance, the arrangement of the plurality of waste suction channels 11 is the same as the arrangement of the plurality of ejector pins 12, a hollow punch 13 is disposed on the lower surface of the cutting die 10 corresponding to each waste suction channel 11, the hollow punch 13 and the cutting die 10 can be integrated, the hollow punch 13 is machined by a CNC milling machine, in order to save the machining cost of the die, the hollow punch 13 can be fixed on the lower surface of the cutting die 10 by a screw 131, the hollow punch 13 is communicated with the waste suction channels 11, the hollow punch 13 is in a circular taper shape, an included angle between the taper at the bottom end of the hollow punch and the waste suction channels is 21 °, the edge of the waste and the edge of the small hole have some wire drawing contacts, the waste in the small hole after die cutting is cut is pressed down by the hollow punch 13, the waste is completely separated from the product, thereby facilitating the absorption of the subsequent waste absorption channels, and improving the absorption efficiency of the absorption channels 11.

Offer on the backing plate 20 with the thimble corresponding and the bottom opening be the exhaust passage 21 of horn mouth form 211, set the bottom opening through with exhaust passage 21 to horn mouth form 211, be favorable to getting rid of the waste material passageway with ejecting waste material, prevent useless jam, because the exhaust passage bottom is the horn mouth form, in order to further reduce the processing cost of exhaust passage 21 on the backing plate, the event sets up recess 22 with backing plate 20 bottom correspondence exhaust passage department, and set up the collecting box (not shown in the drawing) that is used for collecting the waste material below the recess.

The utility model discloses the theory of operation: after the product is die-cut, the material belt is stepped to the waste removing device, firstly, the cutting die 10 moves downwards to be closed with the backing plate 20, in the moving downwards process, the hollow punch 13 on the lower surface of the cutting die 10 firstly presses the waste in the hole downwards to separate the edge of the waste from the edge of the small hole, then the adsorption channel 11 upwards adsorbs the waste, meanwhile, the thimble 12 is inserted into the hole, and the residual waste in the hole is ejected out along the waste discharge channel 21. The utility model discloses a set up hollow drift 13 in cutting die 10 lower surface corresponding every inhale useless passageway 11 department, after cutting die 10 moves down will push down the waste material in the aperture after the cross cutting first, make the waste material break away from with the product completely, be favorable to follow-up absorption passageway to adsorb the waste material, improve the absorption efficiency who adsorbs the passageway; by arranging the plurality of adsorption channels 11 and the plurality of ejector pins 12 used for ejecting waste materials on the cutting die 10, the distance between the adsorption channels 11 and the ejector pins is a stepping distance, waste materials are ejected while waste materials are sucked, each small hole of a product is subjected to two times of waste discharge, one time of waste discharge is adsorption waste discharge, the other time of waste discharge is ejector pin waste discharge, and the waste materials in the small holes are completely discharged.

The above embodiments are only for illustrating the technical conception and characteristics of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, and the protection scope of the present invention cannot be limited thereby.
