Description

Technical Field

[0001] The utility model relates to the technical field of cutting of zipper injection molding machines, in particular to a dotting and cutting device of a zipper injection molding machine. Background Art

[0002] According to the material of the zipper, zippers are divided into three categories: metal zippers, nylon zippers, and resin zippers. Metal zipper teeth are arranged by copper or aluminum wire through a tooth arrangement machine. Nylon zipper teeth are made of nylon monofilament wrapped around a center line through a heated mold. Resin zipper teeth are made of polyester plastic rice through dye matching and arranged by an injection molding machine. During the production process of resin zippers by injection molding machines, dotting and cutting operations are required.

[0003] For example, the patent document with announcement number CN 220562094 U discloses a raw material cutting device for an injection molding machine, comprising a base plate, the top of the base plate is fixedly connected to a support frame, the interior of the support frame is fixedly connected to a cutting mechanism, the top of the base plate is fixedly connected to a baffle, the top of the baffle is fixedly connected to a pushing mechanism, the cutting mechanism comprises a cutting blade, a cylinder, a positioning block, a slider and a slide, the top of the cylinder is fixedly connected to the support frame, and the top of the positioning block is fixedly connected to the output end of the cylinder. The beneficial effect of the present utility model is that by setting the cutting mechanism, after the raw material of the injection molding machine is placed, the output end of the cylinder drives the positioning block to move, and when the positioning block moves, it drives the slider to move inside the slide, and the cutting blade can also move accordingly, which can cut the raw material of the injection molding machine, thereby facilitating use.

[0004] However, when using this structure in the dot cutting process of the zipper injection molding machine, it is impossible to perform adaptive protective pulling operations on the two ends of the cut part of the resin zipper, and the problem of zipper deformation is very likely to occur. At the same time, the equipment cannot perform more stable upper and lower docking limit operations on the cutting of the resin zipper, and irregularities will appear at the incision, which cannot meet daily use needs. Therefore, it is urgent to design a dot cutting device for the zipper injection molding machine to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a dot cutting device for a zipper injection molding machine, so as to solve the problem proposed in the above background technology that the existing structure cannot perform adaptive protective pulling operations on the two ends of the cut part of the resin zipper during the dot cutting process of the zipper injection molding machine, and the zipper is easily deformed by pulling. At the same time, the equipment cannot perform more stable upper and lower docking limit operations on the cutting of the resin zipper, and irregularities will appear at the incision, which cannot meet daily use needs.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a dotting and cutting device for a zipper injection molding machine, comprising a supporting base frame, a cutting frame fixedly connected to the center of the surface of the supporting base frame, electric push rods provided on both sides of the interior of the cutting frame, and a lifting frame fixedly connected to the top end of the electric push rod;

[0007] A U-shaped pulling frame is fixedly connected to both sides of the cutting frame, and both sides of the U-shaped pulling frame are fixedly connected to the feeding inclined frame.

[0008] Preferably, both sides of the conveying inclined frame are fixedly connected with a conveying seat, and a conveying trough is provided on the surface of the conveying seat.

[0009] Preferably, a conveyor inclined plate is provided at the inner center of the conveyor inclined frame, and a pulling protection roller is provided at one end of the conveyor inclined plate.

[0010] Preferably, shrinkage frames are provided on both sides of the inner wall of the U-shaped pulling frame, and shrinkage air cushions are provided inside the shrinkage frames.

[0011] Preferably, a shrinkage pad is provided between the two groups of shrinkage air cushions.

[0012] Preferably, a downward-pressing cutting frame is fixedly connected to the bottom center of the lifting frame, and a cutter body is provided at the bottom end of the downward-pressing cutting frame.

[0013] Preferably, a docking airbag is provided at the center of the inner bottom wall of the cutting frame, and a docking knife seat is fixedly connected to the top end of the docking airbag.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The dotting and cutting device of the zipper injection molding machine can complete the dotting and cutting operation that is more suitable for pulling at both ends of the zipper injection molding machine through the supporting base frame, U-shaped pulling frame, feed inclined frame, feed seat, feed trough, feed inclined plate, pulling protection roller, shrinking frame, shrinking air cushion, shrinking air cushion and shrinking joint pad. In the actual use process, the staff first inserts the zipper that needs to be dotted and cut into the feed trough of the feed seat at one end, and then passes through the central cutting frame along the feed inclined plate inside the feed inclined frame, and then passes out along the feed inclined frame and feed seat on the back to quickly arrange the zippers. During loading and unloading operations, when the zipper is dotted and cut inside the cutting frame, the downward cutting force can drive the zipper to be pressed down inside the U-shaped pulling frame on both sides of the cutting frame, and the shrinkage air cushion is pulled open at the shrinkage joint in the center. Then, under the limit of the shrinkage air cushion and the shrinkage joint, the limited pulling operation at both ends is performed downward. At the same time, during the pulling process, the feed inclined plate can quickly pull and roll the zippers at both ends through the pulling protection roller at one end, thereby ensuring the limited protection effect of the zipper on the pulling at both ends during the dotted cutting process to the greatest extent, reflecting the practicality of the equipment design.

[0016] The dotting and cutting device of the zipper injection molding machine further improves the overall use effect of the equipment through the setting of the cutting frame, electric push rod, lifting frame, downward pressure cutting frame, cutter body, docking airbag and docking knife seat. In daily use, the staff can start the electric push rods on both sides of the cutting frame to drive the lifting frame at the top to perform lifting and lowering adjustment, so that the downward pressure cutting frame at the bottom center of the lifting frame drives the cutter body at one end to be pressed downward. At the same time, the docking airbag at the center of the bottom wall of the cutting frame can adaptably connect the docking knife seat at the top to the cutter body at the bottom end of the downward pressure cutting frame. The two are stably docked and squeezed up and down, thereby ensuring that the incision at the zipper dotting and cutting is more complete, reflecting the comprehensiveness of the equipment design.
