TECHNICAL FIELD

[0001] The utility model relates to the field of mylar processing technology, specifically to computer touchpad mylar die cutting carrier. BACKGROUND

[0002] Mylar is a film made of dimethyl terephthalate and ethylene glycol with the help of related catalysts, through ester exchange and vacuum polycondensation, biaxial stretching, which can be used as insulation material for fans, capacitors, coils, cables, and can also be made into composite insulation material with barley paper. In the production process of mylar, it is necessary to carry out die cutting processing on mylar.

[0003] For example, a kind of die cutting special carrier for insulating flame-retardant mylar, (publication number: CN219987804U), including mylar die cutting plate, the upper surface right end of mylar die cutting plate is equipped with dust removal mechanism, dust removal mechanism includes dust removal seat, dust removal seat is internally provided with the opening of through arrangement, and the inner wall top end, bottom end of opening is equipped with dust cover, dust cover is equipped with multiple dust suction ports, the left side of dust removal seat is equipped with two groups of stand, two groups of stand are internally provided with the slot of through arrangement, the slot is slidably connected with slide, the front end surface of slide is rotatably connected with limit roller, the top of stand is vertically connected with adjusting bolt, and the bottom of adjusting bolt is connected with the upper surface of slide, can clean the dust on the surface of insulating flame-retardant mylar in two directions, avoid the influence of static electricity of insulating flame-retardant mylar on its die cutting;And can limit the position of die cutting insulating flame-retardant mylar, avoid insulating flame-retardant mylar in die cutting process.

[0004] Based on the above patent search, and combined with the equipment in the prior art, the above-mentioned equipment lacks the structure for guiding and conveying mylar when it is applied. When the mylar is conveyed into the opening of the dust removal seat, due to the difference in height between the bottom of the opening and the dust cover and the surface of the mylar die cutting plate, if the edge of the opening or the dust cover contacts the surface of the mylar when the mylar passes through the opening of the dust removal seat, it may cause the surface of the mylar to be scratched or damaged, thereby affecting the quality and appearance of the product. At the same time, the height difference may cause the mylar to deviate in position during conveying, especially in the case of high-speed conveying or thin material, the deviation in position may affect the subsequent die cutting precision and product quality. In addition, due to the inconsistency in height, the mylar may be subjected to uneven tension or pressure when passing through the opening, causing the material to wrinkle or bend. These defects not only affect the appearance of the product, but also may affect the functionality and service life of the product. Therefore, we need to propose a computer touchpad mylar die cutting carrier. UTILITY MODEL CONTENTS
