Description

Technical Field

[0001] The utility model relates to the technical field of elastic band edge wrapping tension control devices, in particular to an elastic band edge wrapping tension control device for garment processing. Background Art

[0002] The elastic band edge wrapping tension control device for garment processing, namely the edge binder of an industrial sewing machine, is also called a flat-bed sewing machine edge binder, a draw-in hemming device or a hemming device. It is a commonly used auxiliary device in the garment manufacturing industry. It is mainly used to wrap elastic bands, rubber bands or other elastic materials around the edges of garments or other fabric products to increase the elasticity and durability of the products.

[0003] When processing garments and sewing elastic bands into the interior of fabrics, it is necessary to stretch the elastic bands by a certain length. In the prior art, the elastic bands are often passed through between two plates, and springs are arranged on the plates. By controlling the compression amount of the springs, the pressure exerted on the elastic bands by the plates is changed, so that the elastic bands need to overcome this pressure when being stretched, thereby enabling the elastic bands to have a certain degree of deformation when moving. However, the resistance received by the elastic bands depends on the magnitude of the pressure exerted on the elastic bands by the plates and the friction coefficient between the plates and the elastic bands. Different types of elastic bands have different friction coefficients, so it is impossible to accurately judge the tightness of the elastic bands directly according to the compression amount of the springs, and this method cannot intuitively and accurately reflect the tightness of the elastic bands, and it is also impossible to visually detect even if the plates become loose during use.

[0021] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Embodiment

[0023] As Figure 1 shown, a rubber edge wrapping and tension control device for garment processing proposed by the present utility model includes a connecting seat 1, a distance adjusting member 2 is slidably installed on the connecting seat 1, the connecting seat 1 includes a connecting plate 101, a connecting groove 102 is provided on the connecting plate 101, and a fastening bolt 103 is movably installed in the connecting groove 102. The connecting plate 101 can be fixedly installed on the sewing machine through the fastening bolt 103. The distance adjusting member includes an adjusting plate 201 slidably installed on the connecting plate 101, a sliding groove 202 is provided on the adjusting plate 201, and two positioning bolts 203 are threadedly connected to the connecting plate 101, and the positioning bolts 203 are located inside the sliding groove 202. Loosening the two positioning bolts 203 can make the positioning bolts 203 not press the adjusting plate 201. At this time, the adjusting plate 201 can be slid. After the adjusting plate 201 is adjusted to a suitable distance, rotating the positioning bolts 203 can press and fix the adjusting plate 201 through the positioning bolts 203.

[0024] Furthermore, a supporting plate 3 is fixedly installed on the distance adjusting member 2, and a winding structure 4 for winding the garment and guiding the rubber into the garment is installed on the supporting plate 3. The winding structure includes a first guiding cover 401 and a second guiding cover 402 fixedly installed on the supporting plate 3, and the second guiding cover 402 is located inside the first guiding cover 401. The edge of the fabric is passed through the first guiding cover 401, and the rubber band is passed through the second guiding cover 402. Under the guiding action of the arc-shaped structure of the first guiding cover 401, the fabric can be bent for edge wrapping treatment, and the rubber band can be wrapped therein (this is the prior art and will not be elaborated here).

[0025] As Figures 2 to 4As shown in the figure, it further includes a pressure regulating component 5 installed on the support plate 3. The pressure regulating component 5 includes a pressing component and an elastic force detecting component. The pressing component adjusts the resistance applied to the rubber band, and the elastic force detecting component detects the elastic force of the rubber band after being stretched under the action of the resistance. The pressing component includes slideways 501 provided on both sides of the support plate 3. A slider 502 is slidably installed in the slideways 501. A lead screw 503 is fixedly installed on one of the sliders 502, and a guide rod 504 is fixedly installed on the other slider 502. A bottom plate 505 is fixedly installed on the lead screw 503 and the guide rod 504. A pressing plate 506 is slidably installed on the guide rod 504. Pass the rubber band through between the bottom plate 505 and the pressing plate 506, and then by changing the pressure applied by the pressing plate 506 to the rubber band, the magnitude of the resistance received by the rubber band during movement can be adjusted, thereby the tightness of the rubber band can be changed. And when the rubber band moves, it will drive the slider 502 to slide in the slideway 501.

[0026] Furthermore, the pressing component further includes an adjusting pressing plate 507 slidably installed on the guide rod 504. A plurality of pressing springs 508 are fixedly installed on the adjusting pressing plate 507. The other ends of the pressing springs 508 are fixedly connected to the pressing plate 506. A nut 509 is rotatably installed on the adjusting pressing plate 507, and the nut 509 is threadedly connected to the lead screw 503. By rotating the nut 509, the adjusting pressing plate 507 can be driven to move up and down, so that the compression amount of the pressing spring 508 can be adjusted, and thus the pressing spring 508 can apply pressure to the pressing plate 506, and thus the magnitude of the pressure applied by the pressing plate 506 to the rubber band can be controlled.

[0027] Among them, the elastic force detecting component includes a column 510 fixedly installed on the support plate 3. A connecting block 511 is fixedly installed on the column 510. A pulling block 512 is fixedly installed on the guide rod 504. A pulling spring 513 is fixedly installed between the connecting block 511 and the pulling block 512. A pull rod 514 is fixedly installed on the pulling block 512. A scale 515 is provided on the pull rod 514. A pointer 516 is fixedly installed on the connecting block 511. When the rubber band moves, due to the certain frictional force between the rubber band and the pressing plate 506 and the bottom plate 505, the moving rubber band will drive the slider 502 to slide inside the slideway 501, so that the guide rod 504 and the pulling block 512 can be driven to move. The pulling block 512 will drive the pull rod 514 to move and stretch the pulling spring 513. The stretched pulling spring 513 will apply a pulling force to the pulling block 512. When the pulling force applied by the pulling spring 513 to the pulling block 512 is equal to the sum of the frictional force applied by the pressing plate 506 and the bottom plate 505 to the rubber band, the elastic force generated by the self-elastic deformation of the rubber band, and the pulling force received by the rubber band during movement, the rubber band is in a force balance state. At this time, the scale 515 corresponding to the pointer 516 can represent the tightness of the rubber band at this time. And when the tightness of the rubber band changes significantly, the scale 515 pointed to by the pointer 516 will change significantly.

[0028] It should be noted that during sewing work, the sewing speed is constant and the stretching degree of the rubber band is constant. Therefore, the elastic force generated by the elastic deformation of the rubber band itself and the pulling force received when the rubber band moves are constant. Therefore, the change in the scale 515 pointed to by the pointer 516 can only be caused by the frictional force exerted on the rubber band by the pressing plate 506 and the bottom plate 505. Thus, the magnitude of the frictional force exerted on the rubber band by the pressing plate 506 and the bottom plate 505 can be reflected by the change in the scale 515, and the tightness of rubber bands made of different materials can be accurately and intuitively controlled.

[0029] As Figure 1 shown, in this embodiment, a positioning rod 6 is fixedly installed on the support plate 3. The rubber band will pass through the positioning rod 6 and then enter the second feeding cover 402. Under the action that the positioning rod 6 and the rubber band can deform, the rubber band can be smoothly attached to the positioning rod 6 to prevent the rubber band from bending.

[0030] Working principle: Pass the rubber band through between the bottom plate 505 and the pressing plate 506. By rotating the nut 509, the adjusting pressing plate 507 can be driven to move up and down, so that the compression amount of the pressing spring 508 can be adjusted. Thus, pressure can be exerted on the pressing plate 506 through the pressing spring 508, and the magnitude of the pressure exerted on the rubber band by the pressing plate 506 can be controlled. That is, the magnitude of the resistance received when the rubber band moves can be adjusted, and thus the tightness of the rubber band can be changed.

[0031] When the rubber band moves, due to the certain frictional force between the rubber band and the pressing plate 506 and the bottom plate 505, the moving rubber band will drive the slider 502 to slide inside the slideway 501, thereby being able to drive the guide rod 504 and the pulling block 512 to move. The pulling block 512 will drive the pull rod 514 to move and stretch the tension spring 513. The stretched tension spring 513 will exert a pulling force on the pulling block 512. When the pulling force exerted by the tension spring 513 on the pulling block 512 is equal to the sum of the frictional force exerted on the rubber band by the pressing plate 506 and the bottom plate 505, the elastic force generated by the elastic deformation of the rubber band itself, and the pulling force received when the rubber band moves, the rubber band is in a force balance state. At this time, the scale 515 corresponding to the pointer 516 can represent the tightness of the rubber band at this time, and when the tightness of the rubber band changes significantly, the scale 515 pointed to by the pointer 516 will change significantly.

[0032] The above specific embodiments are only several alternative embodiments of the present invention.
