Description

Technical Field

[0001] The utility model relates to the technical field of hot cutting of braided elastic band edge wrapping, and in particular to a device for hot cutting of braided elastic band edge wrapping. Background Art

[0002] Braided elastic band hemming is a common clothing accessory, mainly used for the collar, cuffs, hem and other parts of clothing to increase the aesthetics and comfort of clothing. When the braided elastic band hemming is hot-cut, melted material debris will be left at the hot-cutting edge. Long-term accumulation will cause irregularities at the incision and affect subsequent hot-cutting processing, so it needs to be scraped off regularly. Currently, scraping is mostly done manually, and the operation process is cumbersome and complicated, which increases the workload of the staff and is not conducive to the staff's operation. Therefore, it is necessary to provide a braided elastic band hemming hot-cutting device to solve the above technical problems. Utility Model Content

[0003] The utility model aims to provide a braided elastic band edge wrapping hot cutting device to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A woven elastic band hemming hot cutting device comprises a bottom box; a mounting bracket is symmetrically fixedly installed at one end of the top of the bottom box, a material rolling roller is rotatably connected between two of the mounting brackets, a material guide plate is fixedly installed at one end of the two mounting brackets away from the material rolling roller, the top of the material guide plate is symmetrically rotatably connected with an adjusting bolt, and the top outer sides of the two adjusting bolts are respectively threadedly connected to the two ends of a pressing plate, a vertical plate is symmetrically fixedly installed at one end of the top of the bottom box away from the mounting bracket, a top frame is fixedly installed at the top of the vertical plate, a cylinder is fixedly installed at the center of the top of the top frame, the output end of the cylinder extends to the bottom of the top frame and is fixedly connected with a hot cutting knife, and the two ends of the hot cutting knife are respectively slidably connected to the side of the vertical plate;

[0006] The motor is fixedly mounted on the top of the inner wall of the bottom box, one side of the inner wall of the bottom box is rotatably connected to a worm, the output end of the motor is fixedly connected to one end of the worm, and the two sides of the bottom box are symmetrically fixedly connected to limiting frames, and through grooves are provided on both sides of the bottom box, and the two limiting frames are rotatably connected to the sides close to each other, and the two-way screw rods pass through the through grooves, and the central position of the two-way screw rods is fixedly connected to a worm wheel, and the worm wheel is meshed with the worm, and the outer side of the two-way screw rod is symmetrically threadedly connected to two connecting frames, and the connecting frame is slidably connected to the limiting frame, and a mounting plate is fixedly mounted on the top of the connecting frame, and a scraper is fixedly mounted on one side of the mounting plate, and the scraper is slidably connected to the side wall of the vertical plate.

[0007] The above technical scheme is adopted. In this scheme, since residual hot-cutting melt will be attached to the blade of the hot-cutting blade during hot-cutting of the braided elastic band, in order to increase the uniformity of the incision of the braided elastic band during hot-cutting, the melt on the blade needs to be removed. The molten material on the surface of the hot-cutting knife is scraped off by symmetrically arranged scrapers on the equipment through the bidirectional transmission of the bidirectional lead screw. During scraping, in order to maintain the movement stability and synchronization of the scraper, a self-locking power transmission structure is formed on the equipment through a worm and a worm gear. The bidirectional lead screw is driven to rotate by a motor in conjunction with the worm and the worm gear. The bidirectional movement mechanism of the bidirectional lead screw cooperates with the symmetrically arranged scrapers. The scraping work can be carried out quickly. The symmetrically arranged scrapers can shorten the scraping time by half, and the scraping of the molten material can be completed more quickly. In order to increase the movement stability of the scraper, a connecting frame is provided on the bidirectional screw rod for guidance. In order to increase the stability of the connecting frame during movement, a limiting frame is provided under the connecting frame to slide with it, so that the connecting frame can maintain linear movement and increase the operation stability of the equipment. When the equipment is running, the woven elastic band to be hot-cut needs to be transported to the hot cutting knife. The material passes through the guide plate and the pressure plate and is adjusted by adjusting the bolts so that the guide plate and the pressure plate can guide the material separately and orderly, making the operation of the equipment more stable.

[0008] A further improvement of the technical solution of the utility model is that: the top of the guide plate is equidistantly provided with guide grooves cooperating with the material roll, and the bottom of the pressure plate is provided with a convex block cooperating with the guide groove at the top of the guide plate.

[0009] By adopting the above technical solution, the material guide groove arranged at the top of the guide plate can guide the material on the material roller in an orderly and separate manner to avoid the material from being entangled during transportation. In order to prevent the material from falling off the guide plate during transportation, the lower surface of the pressure plate is equidistantly provided with protrusions that are plugged into the guide plate, which can better limit the transportation of the material.

[0010] A further improvement of the technical solution of the utility model is that a reinforcing bracket is provided on one side of the vertical plate.

[0011] By adopting the above technical solution, the reinforcement bracket is provided to increase the installation stability of the vertical plate, so that the equipment remains stable during long-term operation and the service life of the equipment is increased.

[0012] A further improvement of the technical solution of the utility model is that: the limiting frame is arranged in an L shape, and the end of the limiting frame is provided with a connecting protrusion that is connected and matched with the bidirectional screw rod.

[0013] By adopting the above technical solution, the L-shaped limiting frame can be connected to the end of the bidirectional screw rod and the side wall of the bottom box respectively, thereby increasing the installation stability of the end of the bidirectional screw rod, so that the equipment can operate stably. In order to increase the connection fit between the limiting frame and the bidirectional screw rod, the end of the limiting frame is provided with a connecting protrusion that cooperates with the bidirectional screw rod, so that the connection between the two is more stable.

[0014] A further improvement of the technical solution of the utility model is that: a connecting ring threadedly connected to the bidirectional screw rod is provided at one end of the connecting frame, and a connecting column mounted and matched with the mounting plate is provided at the other end of the connecting frame.

[0015] By adopting the above technical solution, the connecting ring at the end of the connecting frame facilitates the threaded connection between the connecting frame and the bidirectional screw rod, so that the bidirectional screw rod can drive the connecting frame to move, and the connecting column at the other end of the connecting frame can increase the connection fit between the connecting frame and the mounting plate, so that the connecting frame can more stably drive the mounting plate to move.

[0016] A further improvement of the technical solution of the utility model is that: a connecting ring at the bottom end of the connecting frame is provided with a guide groove which is slidably matched with the limiting frame.

[0017] By adopting the above technical solution, a connecting ring at the bottom of the connecting frame is provided with a guide groove that slides with the limiting frame. The setting of the guide groove can make the connecting frame more stable when sliding and prevent the connecting frame from rotating when moving.

[0018] A further improvement of the technical solution of the utility model is that a connecting protrusion is provided on one side of the scraper.

[0019] By adopting the above technical solution, the connection protrusion on one side of the scraper can increase the connection area between the scraper and the vertical plate, so that the scraper is more stable when sliding on the vertical plate.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

During the scraping, in order to maintain the moving stability and synchronization of the scraper 18, a self-locking power transmission structure is formed on the equipment through the worm 11 and the worm wheel 13, and the motor 12 cooperates with the motor 12 to transmit the melt to the surface of the hot cutting knife 10. The worm 11 and the worm wheel 13 drive the bidirectional screw 14 to rotate. The bidirectional movement mechanism of the bidirectional screw 14 cooperates with the symmetrically arranged scraper 18 to quickly perform the scraping work.
