Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment and relates to a die-cut product stripping device. Background Art

[0002] The popularity of automated die-cutting and laminating machines has effectively replaced manual laminating, reducing labor and time and improving efficiency. Before the die-cutting and laminating machine performs the laminating process, the roll-shaped die-cut products need to be peeled off from the corresponding tape film. This process is generally completed by pulling down the tape with a peeling knife. However, for a variety of die-cut products, such as Figure 4 The instant noodle product shown has an asymmetric structure, so the defective rate of this type of product during the peeling process is too high, which seriously affects the production efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a die-cut product stripping device in order to overcome the defects of the above-mentioned prior art, so as to solve the problem of excessively high stripping defect rate of irregular asymmetric die-cut products.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A die-cut product peeling device is used to peel the die-cut product from a material strip film, the material strip film includes a plurality of divided material strips arranged in parallel along the width direction, and the die-cut product is attached to the plurality of divided material strips at the same time;

[0006] The device comprises a strip film recovery unit, and a feeding unit, a material separation plate, a stripping knife, and a die-cut product recovery unit which are sequentially arranged along the conveying direction of the die-cut product;

[0007] One end of the material dividing plate extends in a stepped manner along the conveying direction of the die-cut product, and each step is respectively matched with a corresponding material dividing belt;

[0008] During operation, multiple dividing strips are pulled by the strip film recovery unit and are peeled off from the die-cut products in batches along the stepped end edges of the dividing plates. The die-cut product is peeled off from the last dividing strip by a peeling knife and then recovered by adsorption by the die-cut product recovery unit.

[0009] As a preferred technical solution, among multiple dividing tapes, the gram weight of the dividing tape that is first peeled off from the die-cut product is lower than the gram weight of the dividing tape that is last peeled off from the die-cut product, so that the die-cut product and the corresponding dividing tape can be separated from each other at the stepped end edge through the downward pulling action of the tape film recovery unit.

[0010] Furthermore, the material separation plate comprises a material conveying plate and a material separation auxiliary plate which are sequentially arranged along the conveying direction of the die-cut product, and the stepped end portion is arranged at one end of the material separation auxiliary plate.

[0011] Furthermore, the material dividing auxiliary plate is a "convex" auxiliary plate, and the material strip film includes three material dividing strips arranged in parallel along the width direction.

[0012] Furthermore, one end of the material separation auxiliary plate is provided with an I-shaped slot, and the feed plate and the material separation auxiliary plate are connected via the I-shaped slot, so that the material separation auxiliary plate of the corresponding shape can be replaced for die-cut products of different shapes.

[0013] Furthermore, the feed plate is movably arranged along the conveying direction of the die-cut product, so as to adjust the relative position between the feed auxiliary plate and the stripping knife according to the shape and size of the feed auxiliary plate, thereby achieving better stripping efficiency; in addition, for the die-cut product with regular shape that does not need to use the feed auxiliary plate, the feed auxiliary plate is disassembled and the edge of the feed plate is brought close to the stripping knife to carry out the stripping process. This can be achieved specifically by any existing guide rail, slide seat and slide seat locking device.

[0014] Furthermore, the feeding unit comprises a raw material roller and a plurality of feeding guide rollers which are sequentially arranged along the conveying direction of the die-cut product.

[0015] Furthermore, the strip film recovery unit comprises a receiving roller and a plurality of batch receiving components arranged in parallel between the receiving roller and the material separation plate and between the receiving roller and the stripping knife. The plurality of batch receiving components are respectively used to recover different batches of the material separation strips.

[0016] Furthermore, the batch material collection component includes a plurality of material collection guide rollers arranged in sequence along the conveying direction of the material collection belt. The material collection guide rollers are used to adjust the angle between the material collection belt and the die-cut product when the two are peeled off, thereby achieving a better peeling effect.

[0017] Furthermore, the die-cut product recovery unit includes an adsorption platform.

[0018] Furthermore, the stripping knife is rotatably disposed between the dividing plate and the die-cut product recovery member to facilitate adjustment of the stripping angle between the dividing belt and the die-cut product, thereby achieving a better stripping effect.

[0019] Working principle: Due to the stepped end of the dividing plate and the setting of multiple dividing belts, when the die-cut product is conveyed to the edge of the dividing plate following the material belt film under the traction of the receiving roller, the dividing belt on the shorter part of the end of the dividing auxiliary plate is pulled down, separated from the part of the die-cut product attached thereto, and wound up on the receiving roller, while the die-cut product continues to be attached to other unwound dividing belts through the remaining part until it is conveyed to the corresponding end edge of the dividing auxiliary plate; when the die-cut product is conveyed to the position of the stripping knife, since the die-cut product attached part on the remaining dividing belt is a symmetrical structure with regular shape, the die-cut product is evenly stressed, and the stripping process proceeds smoothly, effectively solving the problem of high stripping defect rate of die-cut products.

[0020] Compared with the prior art, the present invention has the following characteristics:

[0021] 1) This device reduces the contact area between the stripping knife and the die-cut product by stripping in batches, thereby reducing the possibility of poor stripping;

[0022] 2) For irregular die-cut products, the device first peels off the asymmetric part and then peels off the remaining symmetric part with a peeling knife, thereby solving the problem of uneven force on the die-cut product during peeling due to the asymmetry of the overall structure of the die-cut product, which in turn causes a high peeling defect rate;

[0023] 3) This device can realize the automatic stripping of die-cut products, effectively reduce manual operation and human intervention to pollute the products, and has a high stripping efficiency (the stripping defect rate is reduced from 15% to 0.1%). BRIEF DESCRIPTION OF THE DRAWINGS
