Description

Technical Field

[0002] In the textile field, ultrasonic die-cutting is generally used to solve the problem that the seams of traditional stitched products are not smooth and beautiful, and are prone to forming flocculent edges or loose edges. Ultrasonic cutting uses the energy of ultrasound to locally heat and melt the material being cut to achieve the purpose of cutting the material. As a result, textiles formed by ultrasonic die-cutting will harden the edges of the product due to temperature, forming sharp edges and sharp points. In the field of quality inspection of textiles and accessories, the detection of sharp edges is a key link to ensure product safety and process precision.

[0021] In the present invention, the cleaning mechanism includes a dust blowing hood 37 arranged inside the first device groove 24, a second electric telescopic rod 38 is installed on the inner wall of the first device groove 24, the telescopic end of the second electric telescopic rod 38 is fixed on the side wall of the dust blowing hood 37, a dust collection hood 39 is fixed inside the dust blowing hood 37, and a first connecting pipe 3 is connected to the side wall of the dust collection hood 39, the end of the first connecting pipe 3 away from the dust collection hood 39 passes through the dust blowing hood 37 and the placement table 10 and is connected to the dust cleaner 2, dust blowing pipes 40 are fixed on the upper and lower inner walls of the dust blowing hood 37, a dust blowing port facing the dust collection hood 39 is provided on the side wall of the dust blowing pipe 40, a second connecting pipe 5 is connected to the dust blowing pipe 40, the end of the second connecting pipe 5 away from the dust blowing pipe 40 passes through the dust blowing hood 37 and the placement table 10 and is connected to the hair dryer 4, the vacuum cleaner 2 and the hair dryer 4 are both installed at the upper end of the base 1, and the first pressure touch switch 17 is electrically connected to the second electric telescopic rod 38, the vacuum cleaner 2 and the hair dryer 4.

[0022] The developing mechanism includes a photosensitive paper roll 48 arranged inside the third device slot 34. Photosensitive paper is wound on the photosensitive paper roll 48.

The light emitted by the irradiation lamp 33 passes through the first light-transmitting slot 23 and the second light-transmitting slot 28 and irradiates the textile accessory, magnifying the edge of the textile accessory and developing it on the photosensitive paper, leaving a mark on the photosensitive paper. The area of ​​the photosensitive paper illuminated by the light produces a colored shadow, and the unirradiated area retains the original color, thereby enabling the edge of the textile accessory to be magnified and intuitively displayed, making it convenient for people to intuitively observe the sharpness of the edge of the textile accessory.

[0023] A second device groove 25 corresponding to the position of the device frame 8 is provided on the side wall of the vertical frame 6, and a through groove 26 is provided on the inner wall of the second device groove 25. A discharge plate 7 corresponding to the position of the through groove 26 is fixed on the side support of the vertical frame 6. A knife groove 50 is provided inside the vertical frame 6 and is located below the through groove 26 and connected to the through groove 26. A cutting knife 45 is provided inside the knife groove 50. Two movable grooves 27 connected to the knife groove 50 and the second device groove 25 are provided inside the vertical frame 6. A movable rod 41 is provided inside the two movable grooves 27.

The active roller 46 and the driven roller 47 are respectively located on the upper and lower sides of the photosensitive paper. The ends of the active roller 46 and the driven roller 47 are rotatably connected to the second device groove. On the inner wall of the groove 25, gears 43 are installed at both ends of the active roller 46 through one-way bearings 44, and racks 42 are fixed on the side walls of the two movable rods 41. The two racks 42 cooperate with the two gears 43 respectively, and the one-way bearings 44 have a one-way transmission function. When the rack 42 moves down, it can drive the gear 43 to rotate counterclockwise. At this time, since the one-way bearings 44 are in an idling state, the active roller 46 will not rotate. When the rack 42 moves up, it can drive the gear 43 to rotate clockwise. At this time, the active roller 46 is driven by the one-way bearing 44 to rotate clockwise. The active roller 46 and the driven roller 47 cooperate to transport the used photosensitive paper to the left. When the lifting plate 11 moves up to the limit position, the used photosensitive paper is cut off by the cutting knife 45, and the used photosensitive paper is discharged through the discharge plate 7.

[0024] Furthermore, a baffle frame 9 is provided between the placement table 10 and the device frame 8. Two slide bars 19 are fixed to the lower end of the baffle frame 9, and two slide grooves 36 are provided at the upper end of the device frame 8. The two slide bars 19 slide inside the two slide grooves 36 respectively. A connecting block 20 is fixed on the side wall of the baffle frame 9. A connecting bolt 21 is provided through the side wall of the connecting block 20. The connecting bolt 21 is screwed to the side wall of the device frame 8. The baffle frame 9 can be used to enclose the space between the placement table 10 and the device frame 8 to play a light-shielding role.

[0025] When using the present invention, the operator places the textile accessory to be inspected into the placement slot 22 of the placement table 10 so that the edge of the textile accessory is above the first light-transmitting slot 23. The operator then activates the first electric telescopic rod 14 to extend, pushing the connecting frame 16 downward, driving the lifting plate 11 to descend along the guide rod 13. During the descent of the lifting plate 11, when the pressure plate 32 contacts the surface of the textile accessory, the movable rod 31 compresses the spring 30 in the movable slot 29 to generate an elastic pressing force, thereby pressing and securing the textile accessory through the pressure plate 32. Then, when the lifting plate 11 is pressed down to trigger the first pressure-touch switch 17, the second electric telescopic rod 38 can be started to complete an extension and contraction process, and the vacuum cleaner 2 and the hair dryer 4 can be started at the same time. When the second electric telescopic rod 38 is extended, it can push the dust hood 37 out of the first device slot 24 to the inner side of the first light-transmitting slot 23, so that the edge of the textile accessory is placed inside the dust hood 37. At this time, the hair dryer 4 supplies air to the dust blowing pipe 40 through the second connecting pipe 5, and the dust blowing port sprays air toward the edge of the textile accessory. At the same time, the vacuum cleaner 2 sucks dust through the first connecting pipe 3 and the dust hood 39, thereby automatically completing the process of cleaning the edge of the textile accessory. After cleaning is completed, the dust hood 37 is retracted into the inner side of the first device slot 24 by the contraction of the second electric telescopic rod 38; Then, when the lifting plate 11 descends to the limit position, the lifting plate 11 contacts the second pressure-touch switch 18, triggering the second pressure-touch switch 18. The illumination lamp 33 in the lamp box 15 is activated, and the light sequentially passes through the second light-transmitting slot 28, the gap at the edge of the textile accessory, and the first light-transmitting slot 23, and is finally projected onto the photosensitive paper of the photosensitive paper roll 48 laid flat in the third device slot 34 of the device frame 8. The edge of the textile accessory is magnified and developed on the photosensitive paper. The photosensitive paper undergoes a photochemical reaction in the area illuminated by the light, and the area blocked by the textile accessory retains its original color, forming a sharp-edged shadow. Then the first electric telescopic rod 14 contracts, driving the lifting plate 11 to rise, and the rack 42 moves up in the moving groove 27 along with the moving rod 41, driving the gear 43 to rotate clockwise, and the one-way bearing 44 drives the active roller 46 to rotate, cooperating with the driven roller 47 to transport the developed photosensitive paper to the left. When the lifting plate 11 rises to the limit position, the photosensitive paper passing through the inside of the groove 26 is cut by the cutting knife 45, and the cut photosensitive paper slides out through the discharge plate 7.
