The utility model discloses a water-repellent zipper which comprises a first zipper tape and a second zipper tape which are oppositely arranged, and zipper teeth are arranged on the edges of the first zipper tape and the second zipper tape respectively. The zipper head is matched with zipper teeth on the first zipper belt and the second zipper belt and used for controlling opening and closing operation of the zipper. The outer edges of the upper end face and the lower end face of each zipper tooth are respectively provided with a layer of rubber ring, the rubber rings are directly fixed to the surfaces of the outer edges of the zipper teeth through a thermal forming technology, and the rubber rings are firmly connected with the zipper teeth through the material viscosity of the rubber rings. The zipper is suitable for application scenes requiring short-time water-repellent performance, such as backpacks, sportswear, outdoor articles and the like, moisture permeation can be effectively prevented on the premise of low cost, and meanwhile opening and closing smoothness and durability of the zipper are kept.

This invention addresses the shortcomings of existing chemical fiber cutting devices, which, except for short cuts of carbon fiber and glass fiber where length precision is not critical, typically employ fixed-length cutting mechanisms and guillotine-type cutters, requiring manual feeding of the cutter after each cut. To reduce the repetitive process of manually pulling the fiber bundle from the cut surface to the fixed end after cutting, this invention designs a cutting disc mechanism for chemical fiber cutting, comprising: a circulating clamping device for conveying the chemical fiber to a fixed length; clamping and tightening rails located on both sides of the clamping part of the circulating clamping device for adjusting the clamping part; a movable cutting disc device located inside the circulating clamping device, on the upper side of the conveying plane; and a movable support device located inside the circulating clamping device, on the lower side of the conveying plane, cooperating with the movable cutting disc device to cut the chemical fiber held by the circulating clamping device.

The utility model discloses a sponge type permeable asphalt pavement structure with high durability, and relates to the technical field of asphalt pavements, the sponge type permeable asphalt pavement structure comprises a roadbed, a wear-resistant layer and road shoulder grooves, a cushion layer is paved on the top surface of the roadbed, the left side and the right side of the roadbed are provided with the road shoulder grooves, the drainage end of a water collecting hopper is connected with a vertical drainage pipe, and the vertical drainage pipe is connected with a water outlet of the water collecting hopper. And vertical drainage ditches and transverse drainage ditches are longitudinally and transversely formed in the permeable bottom base layer, the cushion layer and the roadbed respectively. The multi-layer drainage system is designed and comprises the vertical drainage pipes, the transverse drainage pipes, the vertical drainage grooves and the transverse drainage grooves, a three-dimensional and efficient drainage network is formed, and the vertical drainage pipes and the transverse drainage pipes are communicated with the road shoulder grooves. The vertical drainage grooves and the transverse drainage grooves are also communicated with the road shoulder grooves, it is ensured that rainwater can be rapidly drained from the interior of the pavement structure or drained into the road shoulder grooves, and pavement water accumulation is effectively prevented.

The utility model provides an auxiliary support for template processing, and relates to the technical field of template processing. According to the utility model, the auxiliary bracket assembly is arranged at the top of the bottom plate, the bracket is used for supporting a template or a workpiece, a plurality of insert cores and demolding insert cores are arranged on the bracket, the design of the insert cores and the demolding insert cores is mainly used for providing flexible adjusting and fixing functions, and the template or the workpiece is placed on the bracket; close combination of the template and the support is ensured through the insert cores, movement or deviation of the template in the machining process is prevented, the template can be conveniently separated from the support after machining is completed due to the arrangement of the demolding insert cores, the difficulty in manual demolding and the possible precision problem are avoided, and the machining efficiency is improved. The first demoulding insert core is used for preliminary loosening when the template is separated, and the second demoulding insert core and the third demoulding insert core provide a more accurate and stable demoulding function, so that demoulding is completed on the premise that the template is not damaged.

This disclosure provides a shrink label and a packaging container. The shrink label includes a shrink film layer, a varnish layer with a soft touch, and an graphic information layer. The varnish layer is disposed on the surface of the shrink film layer. The graphic information layer is disposed on the inner layer of the shrink film layer. The packaging container includes a bottle and the shrink label. This shrink label helps to reduce the surface hardness of the shrink label and improves the feel of the shrink label.
