Description

Technical Field

[0001] This utility model relates to the field of pressing and flattening the curled edges of shoe material pieces, and in particular to a positioning component for pressing and flattening the curled edges of shoe material pieces. Background Technology

[0002] The uppers of athletic shoes are usually composed of pieces of various materials. During the cutting and processing, the edges are prone to curling. It is necessary to use a shoe material piece curling edge pressing and positioning component to press the shoe material pieces together, thereby ensuring that the shoe material pieces are flat and accurate during the sewing and bonding process, and improving the overall quality and comfort of athletic shoes.

[0003] In the existing shoe material cutting edge curling and flattening positioning component, the pressure roller on the shoe material cutting piece is prone to fiber shedding during the pressing process. This can cause the detached fibers to adhere to the surface of the pressure roller, resulting in indentations on the shoe material cutting piece during flattening and thus affecting the flattening effect. Utility Model Content

[0004] Therefore, it is necessary to provide a shoe material cutting edge curling and flattening positioning component to address the problem that detached fibers easily adhere to the surface of the pressure roller, which can easily cause indentations in the shoe material cutting pieces during flattening.

[0005] The device includes: a flattening frame, with a mounting frame slidably connected to the upper end of the inner wall of the flattening frame; two electric push rods fixedly connected to the upper end of the inner wall of the flattening frame; the telescopic ends of the electric push rods fixedly connected to the top of the mounting frame; and several pressure rollers rotatably connected to the inner walls of both the flattening frame and the mounting frame; and an anti-attachment mechanism, including an adsorption frame and a baffle frame fixedly connected to the ends of the flattening frame and the mounting frame; a vacuum pump and a dust suction pipe fixedly connected to the inner wall of the adsorption frame; and the surface of the dust suction pipe fixedly connected to the inner wall of the baffle frame.

[0006] In one embodiment, the anti-adhesion mechanism further includes a rubber plate snapped onto the inner wall of the adsorption frame, with a first filter frame fixedly connected to the rear end of the rubber plate and a second filter frame fixedly connected to one side of the first filter frame.

[0007] In one embodiment, the surface of the first filter frame is frustum-shaped, and the surface of the second filter frame is flat-topped cone-shaped.

[0008] In one embodiment, a fixing block is fixedly connected to both sides of the adsorption frame, and a pressure block is rotatably connected to the inner wall of the fixing block.

[0009] In one embodiment, a coil spring is fixedly connected to the surface of the pressure block, and the other end of the coil spring is fixedly connected to the surface of the fixing block.

[0010] In one embodiment, a cast iron rod is slidably connected to the inner wall of the fixing block, and the surface of the cast iron rod is engaged with the inner wall of the pressure block. The elastic force of the coil spring drives the pressure block to rotate at an angle, so that the rear end of the pressure block abuts against the front end of the rubber plate. The cast iron rod is engaged within the pressure block, thereby locking the pressure block and ensuring a stable seal on the front end of the adsorption frame. This, in turn, ensures the adsorption effect of the adsorption frame and the suction pipe on the fibers on the surface of the pressure roller.

[0011] In one embodiment, limiting blocks are fixedly connected to both sides of the adsorption frame. The limiting blocks limit the upward movement of the cast iron rod, preventing the cast iron rod from completely detaching from the fixing blocks during the upward movement.

[0012] In one embodiment, a plurality of guide rods are fixedly connected to the rear end of the rubber plate, and the surfaces of the guide rods are slidably connected to the inner wall of the adsorption frame.

[0013] Beneficial effects 1. By combining the adsorption frame, the suction pipe, and the vacuum pump, negative pressure adsorption of fiber impurities adhering to the surface of the pressure roller is achieved. The baffle frame is used to block the suction pipe and the suction area of ​​the pressure roller over a large area, thereby limiting the airflow diffusion range and creating a local high negative pressure zone on the surface of the pressure roller. This improves the adsorption effect of the fibers adhering to the surface of the pressure roller, making it easier to clean the fiber impurities adhering to the surface of the pressure roller in a timely manner. This ensures the cleanliness of the surface of the pressure roller and avoids the formation of indentations on the shoe material pieces when flattening, thus ensuring the flattening effect of the shoe material pieces. 2. The first filter frame, with a frustum-shaped surface, is used to block large fibers from flowing into the second filter frame and reduce the probability of the first filter frame being blocked. The second filter frame, with a flat-topped cone-shaped surface, is used to block fine fibers from flowing into the vacuum pump and reduce the probability of the second filter frame being blocked. This ensures the adsorption effect of the adsorption frame and the dust suction pipe on the surface of the pressure roller, making it easy to clean the fiber impurities attached to the surface of the pressure roller in a timely manner, thus ensuring the cleanliness of the pressure roller surface and avoiding indentations on the shoe material pieces when pressing.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-5 This invention describes a shoe material cut piece edge-pressing and positioning component.

[0019] In one embodiment, a shoe material cut piece edge-pressing and positioning assembly includes: a pressing frame 100, a mounting frame 200 slidably connected to the upper end of the inner wall of the pressing frame 100, two electric push rods 400 fixedly connected to the upper end of the inner wall of the pressing frame 100, the telescopic ends of the electric push rods 400 fixedly connected to the top of the mounting frame 200, and a plurality of pressure rollers 300 rotatably connected to the inner walls of both the pressing frame 100 and the mounting frame 200; and an anti-attachment mechanism 500, which includes an adsorption frame 502 and a baffle frame 501 fixedly connected to the ends of the pressing frame 100 and the mounting frame 200, a vacuum pump 504 and a dust suction pipe 503 fixedly connected to the inner wall of the adsorption frame 502, and the surface of the dust suction pipe 503 fixedly connected to the inner wall of the baffle frame 501.

[0020] It should be noted that several motors are fixedly connected to one side of the pressing frame 100 and the mounting frame 200. The output shaft of the motor is fixedly connected to one end of the pressing roller 300. A PLC controller is installed on one side of the pressing frame 100. The pressing frame 100 is installed on the shoe material cutting machine at a suitable position by bolts and nuts. The specific installation position can be selected according to actual needs, which will not be elaborated here.

[0021] The PLC controller is operated to automatically activate the electric push rod 400. The telescopic end of the electric push rod 400 moves down, causing the mounting frame 200 to move down to a suitable position within the flattening frame 100. After that, the telescopic end of the electric push rod 400 stops moving down. The PLC controller is then operated to automatically activate the motor and adjust the speed of the motor output shaft. After the cutting machine finishes cutting the shoe material, it is conveyed to the surface of the pressure roller 300. The output shaft of the motor rotates, causing the pressure roller 300 to rotate. The rotating pressure roller 300 continuously flattens and positions the warped edges of the shoe material pieces. After flattening, the flattened and positioned shoe material pieces are conveyed to the next process for further operation.

[0022] In this embodiment, the PLC controller is operated to automatically turn on the vacuum pump 504. The rotating pressure roller 300 flattens the raised edges of the shoe material pieces. Under the action of friction, the fibers on the shoe material pieces easily adhere to the surface of the pressure roller 300. The vacuum pump 504 extracts excess air from the adsorption frame 502, forming an adsorption within the adsorption frame 502. The suction pipe 503 then extracts the fibers adhering to the surface of the rotating pressure roller 300. The baffle frame 501 is used to enclose the suction pipe 503 and part of the surface of the pressure roller 300. The end of the baffle frame 501 does not directly contact the surface of the pressure roller 300, so that the suction pipe 503 forms a local high negative pressure area on the surface of the pressure roller 300, allowing the fibers adhering to the surface of the pressure roller 300 to be promptly adsorbed by the suction pipe 503 and transported into the adsorption frame 502.

[0023] like Figure 4-5 As shown, the anti-attachment mechanism 500 also includes a rubber plate 505 that is snapped onto the inner wall of the adsorption frame 502. A first filter frame 506 is fixedly connected to the rear end of the rubber plate 505, and a second filter frame 507 is fixedly connected to one side of the first filter frame 506. The surface of the first filter frame 506 is frustum-shaped, and the surface of the second filter frame 507 is flat-topped cone-shaped. Several guide rods 508 are fixedly connected to the rear end of the rubber plate 505, and the surfaces of the guide rods 508 are slidably connected to the inner wall of the adsorption frame 502.

[0024] In this embodiment, the frames of the first filter frame 506 and the second filter frame 507 are made of rubber components, so that the frames of the first filter frame 506 and the second filter frame 507 are tightly attached to the inner wall of the adsorption frame 502. The mesh aperture on the first filter frame 506 is larger than the mesh aperture on the second filter frame 507, so that the first filter frame 506 can intercept large fibers flowing to the surface of the second filter frame 507, and the second filter frame 507 intercepts fine fibers flowing into the vacuum pump 504. The first filter frame 506, with a frustum-shaped surface, has mostly inclined surfaces, and the second filter frame 507, with a flat-topped cone-shaped surface, has an arc-shaped surface, so that the fibers slide down along the inclined and arc surfaces, reducing the vertical accumulation of fibers, thereby reducing the risk of the first filter frame 506 and the second filter frame 507 being blocked.

[0025] like Figure 3 As shown, both sides of the adsorption frame 502 are fixedly connected to a fixing block 510. The inner wall of the fixing block 510 is rotatably connected to a pressure block 509. The surface of the pressure block 509 is fixedly connected to a coil spring 511. The other end of the coil spring 511 is fixedly connected to the surface of the fixing block 510. The inner wall of the fixing block 510 is slidably connected to a cast iron rod 512. The surface of the cast iron rod 512 is engaged with the inner wall of the pressure block 509. Both sides of the adsorption frame 502 are fixedly connected to a limit block 513.

[0026] In this embodiment, when it is necessary to clean the adsorption frame 502, pull the two cast iron rods 512 upwards away from the pressure block 509, push the two pressure blocks 509 to rotate 90 degrees within their respective fixing blocks 510, so that the rear end of the pressure block 509 is away from the front end of the rubber plate 505, pull the rubber plate 505, so that the first filter frame 506 and the second filter frame 507 are both away from the adsorption frame 502, and the adsorption frame 502, the first filter frame 506 and the second filter frame 507 can be cleaned.

[0027] After cleaning, slide the first filter frame 506 and the second filter frame 507 into the adsorption frame 502, so that the guide rod 508 slides into the adsorption frame 502, thereby locking the rubber plate 505 into the adsorption frame 502, loosening the limiting position of the two pressure blocks 509, and the elastic force of the coil spring 511 pushes the pressure block 509 to rotate 90 degrees in the fixed block 510, so that the rear end of the pressure block 509 abuts against the front end of the rubber plate 505, pushing the cast iron rod 512 down to slide into the pressure block 509, thereby locking the pressure block 509 and locking the rubber plate 505 into the adsorption frame 502.

[0028] Working principle: Vacuum pump 504 extracts excess air from adsorption frame 502, causing adsorption to form inside adsorption frame 502. Dust suction pipe 503 then extracts fibers attached to the surface of rotating pressure roller 300. Baffle frame 501 is used to enclose part of the surface of dust suction pipe 503 and pressure roller 300. The end of baffle frame 501 does not directly contact the surface of pressure roller 300, so that dust suction pipe 503 forms a local high negative pressure area on the surface of pressure roller 300. This allows the fibers attached to the surface of pressure roller 300 to be promptly adsorbed by dust suction pipe 503 and transported to adsorption frame 502. First filter frame 506 intercepts large fibers and flows to the surface of second filter frame 507. Second filter frame 507 intercepts fine fibers and flows to vacuum pump 504.

[0029] It should be noted that the pressure frame 100, mounting frame 200, pressure roller 300, electric push rod 400, vacuum pump 504, and coil spring 511 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the electric push rod 400 and vacuum pump 504 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
