Description

Technical Field

[0001] This utility model relates to the technical field of luggage sealing strip size shaping, specifically to a luggage sealing strip size shaping tooling. Background Technology

[0002] Luggage sealing strips are installed on luggage to improve the overall sealing of the luggage when the zipper is closed. The specifications of luggage sealing strips are customized according to different luggage sizes and models, which often requires different extrusion molds. The extruded sealing strip is cut at fixed points and to a fixed size, depending on the size of different luggage. However, uneven end faces are prone to occur during the cutting process (because the extruded strip is not fully straightened or fed flat).

[0003] Existing sealing strip cutting equipment is prone to uneven end faces, requiring the assistance of clamping fixtures, such as the sealing strip fixed-length cutting device disclosed in CN218699510U. This device includes a worktable, a clamping box on top of the worktable, a clamping mechanism on top of the clamping box, a drive mechanism inside a support, a lifting rod slidably connected to the drive mechanism, a fixing block fixedly connected to the bottom of the lifting rod, a first mounting groove on the bottom surface of the fixing block, a first mounting block installed inside the first mounting groove, and an upper... The cutter has symmetrically symmetrically formed cavities inside the fixing block. Rotating rods are installed inside the two cavities, and a moving mechanism is installed inside the cavities. Holes communicating with the cavities are symmetrically formed on the inner surface of the first mounting groove. This application solves the problem that in the prior art, the cutter blade becomes dull and worn after long-term use, which affects the cutting effect on the sealing strip and requires replacement. However, it is inconvenient to disassemble and replace the upper and lower cutters, thus affecting normal operation. However, in this solution, the rubber strip is not clamped at the moment of cutting, which cannot guarantee the flatness of the end face at the moment of cutting. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for shaping the size of luggage sealing strips, so as to solve the problem that the size cannot be fixed and the end face cannot be neat when the sealing strip is cut at a fixed point in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tooling for shaping the size of a luggage sealing strip includes a tooling body, a pneumatic cutting mechanism, a cutter head, an auxiliary clamping mechanism, and double slots. The tooling body is equipped with an extrusion mechanism and a pneumatic cutting mechanism. The sealing strip is extruded into the extrusion mold at the end of the extrusion mechanism. The pneumatic cutting mechanism is driven by a cylinder to cut the extruded sealing strip at a fixed point. The auxiliary clamping mechanism is arranged opposite to the pneumatic cutting mechanism. A limit groove is formed in the auxiliary clamping mechanism, and a clamping rod is slidably connected in the limit groove. Double slots are fixedly connected to the clamping rod. The distance between the two sides of the double slots is adapted to the thickness of the cutter head. A feeding plate is installed on one side of the double slots, and a dropping plate is fixedly connected to the other side of the double slots. The dropping plate is composed of a horizontally arranged horizontal plate and an inclined horizontal plate.

[0007] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0008] This invention enables precise and sized cutting without damaging the blade. The feeding and unloading plates installed on both sides of the double slots support the extruded rubber strip and allow for directional collection after cutting. When not in use, it can be stored in a minimal space; when in use, it extends to the vicinity of the die opening for supporting, conveying, and oiling the extruded sealing strip, ensuring that the strip is horizontally conveyed during cutting and guaranteeing a neat and aesthetically pleasing cross-section.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figures 1-6 The tooling shown includes a luggage sealing strip sizing fixture, comprising a fixture body 1, a pneumatic cutting mechanism 3, a cutter head 4, an auxiliary clamping mechanism 5, and a double slot 6. The fixture body 1 is equipped with an extrusion mechanism 2 and a pneumatic cutting mechanism 3. The sealing strip is extruded into the extrusion mold at the end of the extrusion mechanism 2. The pneumatic cutting mechanism 3 is driven by a cylinder to cut the extruded sealing strip at a fixed point by the cutter head 4. The auxiliary clamping mechanism 5 is arranged opposite to the pneumatic cutting mechanism 3. A limiting groove 501 is opened in the auxiliary clamping mechanism 5. A clamping rod 502 is slidably connected in the limiting groove 501. The double slot 6 is fixedly connected to the clamping rod 502. The distance between the two sides of the double slot 6 is adapted to the thickness of the cutter head 4. A feeding plate 601 is installed on one side of the double slot 6. A dropping plate 7 is fixedly connected to the other side of the double slot 6. The dropping plate 7 is composed of a horizontally arranged horizontal plate and an inclined horizontal plate.

[0018] This allows the sealing strip to be extruded from the inner end of the extrusion mechanism 2 and then clamped by the double slots 6 on the auxiliary clamping mechanism 5. It is then cut at a fixed point by the cutter head 4 on the pneumatic cutting mechanism 3, ensuring a flat cut surface and a fixed and precise cut strip size.

[0019] A push rod 503 is inserted through the clamping rod 502. The end of the push rod 503 extends into the clamping rod 502 and is connected to a sliding plate 504. An inclined groove is provided on the sliding plate 504. A U-shaped piece 505 is slidably connected in the inclined groove through a ball bearing. A limit rod 506 is fixedly connected to the U-shaped piece 505. The end of the limit rod 506 extending out of the clamping rod 502 is tapered, and its tapered shape meshes with the teeth provided on the side of the limit groove 501. The limit rod 506 is sleeved in a spring 507, and the spring 507 abuts against the inner wall of the clamping rod 502 and the sliding plate 504.

[0020] Pushing the push rod 503 allows for flexible adjustment of the position of the clamping rod 502 within the limiting groove 501, adjusting it to a position where it can contact the side of the extruded rubber strip when it is straightened, and the positions of the double slot 6 and the cutter head 4 correspond to each other.

[0021] An extension plate 602 is slidably connected inside the feeding plate 601. A traction rod 603 is connected inside the extension plate 602 via a sliding groove. The traction rod 603 has a handle. One side of the ink cloth 604 is fixedly connected to the traction rod 603. The other side of the ink cloth 604 is fixedly connected to the linkage rod 605. Multiple sets of ink cloth 604 and linkage rod 605 are provided, and the number of ink cloth 604 and linkage rod 605 is the same. The height of the feeding plate 601 is flush with the height of the opening of the extrusion die on the extrusion mechanism 2. The height of the discharge plate 7 is slightly lower than that of the feeding plate 601.

[0022] When the extruded rubber strip needs to be straightened and conveyed, the feeding plate 601 and the extension plate 602 serve to support and apply oil, ensuring that the rubber strip is flat when it is cut, that the cut end face is neat, and that the friction is reduced after oiling, thus improving the cutting efficiency.

[0023] Working principle of this utility model:

[0024] First, PVC or other plastic raw materials are fed into the extrusion mechanism 2 and then extruded from the mold opening. They need to be pulled outward continuously with the help of traction force and external force. After being straightened, they are cut off at a fixed point and dropped and collected from the blanking plate 7.

[0025] When the rubber strip is extruded from the mold opening, the auxiliary clamping mechanism 5 needs to be adjusted to the correct position. Push the push rod 503 to move the sliding plate 504 and squeeze the spring 507. This will loosen and fix the limiting rod 506, which was originally engaged with the teeth on the inner side of the limiting groove 501. Then it can move flexibly in the limiting groove 501. Move to the appropriate position to release the push rod 503 and fix the position of the clamping rod 502 in the limiting groove 501.

[0026] At this time, the position of the double slot 6 on the clamping rod 502 is just in contact with the side of the extruded sealing strip when it is pulled straight. When the pneumatic cutting mechanism 3 is started, the cutter head 4 can just squeeze and cut with the double slot 6. The cutter head 4 does not collide with the double slot 6, but falls into the double slot 6 without damaging the blade.

[0027] After aligning the double slot 6 with the cutter head 4, the extension plate 602 needs to be pulled out from the feed plate 601, which will cause the ink cloth 604 and the linkage rod 605 to be pulled out and extended together, so that the straightened sealing strip falls onto the ink cloth 604. With the help of the rotation force of the traction roller of the traction mechanism, it is conveyed evenly and smoothly. At the same time as conveying, the strip can be coated with oil to reduce friction.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
