Description

Technical Field

[0001] The present application relates to the technical field of sewing equipment, and in particular to a concealable rolling-in edge sewing machine. Background Art

[0002] In the textile industry, when using a traditional sewing machine to sew trouser waistbands, if the elastic band has been put into the trouser waistbands, the worker needs to put the trouser waistbands on the periphery of the sewing machine frame to sew, and the trouser waistbands are fully tensioned. If the trouser waistbands can move under the drive of the feeding device or can move under the pull of the worker, the worker can complete a circle of neat sewing of the trouser waistbands. When it is necessary to sew larger trouser waistbands, the use of this sewing machine will be limited, because the size of the workbench is fixed, and the sizes of the trouser waistbands to be sewn are different. When the circumference of the trouser waistband is greater than the circumference of the workbench, due to the elastic band inside the trouser waistband, the circumference of the trouser waistband will change due to the size of the pulling force. When the sewing speed is too fast, it will affect the sewing quality, such as uneven axis, trouser waistband wrinkles and other problems. Therefore, the working efficiency of the traditional sewing machine is low and the benefits are not good.

[0003] In order to solve the above problems, the utility model with the authorization publication number CN221522996U discloses a rolling-in type edge sewing machine, including a machine table, a sewing mechanism and a rolling mechanism. The trousers are sleeved on the rolling mechanism, and the trousers are rotatably connected to the rolling mechanism. The rolling mechanism includes a base and a first rolling component and a second rolling component installed on the base. The first rolling component can be slidably installed on the base, and the second rolling component is fixedly installed on the base. The trousers are sleeved between the first rolling component and the second rolling component. The distance between the first rolling component and the second rolling component is adjusted so that the trouser waistband of the trousers is always kept in a taut state during the sewing process. By adjusting the distance between the first rolling component and the second rolling component, the sewing mechanism can be suitable for sewing trouser waistbands of different sizes.

[0004] However, when the factory receives more orders and the orders do not require the making of waistbands of trousers, the equipment originally used for other sewing projects is insufficient to meet the increased orders, resulting in the sewing equipment specifically used for sewing waistbands being idle and no extra sewing equipment being available to process orders; therefore, further improvements can be made.

A gear is arranged below the strip plate 56, and the gear on the gear rod 573 is meshed with the rack seat, and the gear rotation drives the meshed rack plate 56 to move forward or backward, and rotating plates 574 are rotatably arranged at both ends of the gear rod 573, and the rotating plates 574 at both ends are respectively fixedly arranged at the bottom of the workbench 1 in a vertical state, and one end of the gear rod 573 is penetrated by a rotating plate 574, and a second driven wheel 575 is rotatably arranged, and a second moving belt is rotatably arranged between the second driving wheel 572 and the second driven wheel 575, and the rack plate 56 is driven to move through the second moving driving member 57, so that the moving wheel 523 on the moving plate 522 slides on the moving slide rail 512, and then the sliding block 524 on the moving lifting plate 521 follows the L-shaped guide groove 531 for guided movement, so that the second support plate 54 at the top of the moving lifting plate 521 is lifted and lowered.

[0044] The implementation principle of a concealable rolling-in edge sewing machine of the embodiment of the present application is as follows: when the sewing mechanism 2 and the rolling mechanism 4 need to be hidden, first, the worker lowers and hides the rolling mechanism 4 through the controller 11 on the workbench 1, thereby reserving a descending space for the sewing mechanism 2 above it. Specifically, the second mobile driving member 57 drives the second driving gear to rotate, and the second driving gear drives the second driven gear to rotate through the second moving belt, thereby driving the gear on the gear rod 573 to mesh with the rack seat above it, thereby driving the rack seat to move. During the movement of the rack seat, the moving wheel 523 on the moving plate 522 moves in the moving slide rail 512. During the movement, the sliding block 524 on the moving lifting plate 521 moves in the L-shaped guide groove 531 in the second guide plate 53. The moving lifting plate 521 moves downward from the top of the highest point of the guide groove 531 to the bottom through the sliding block 524, and then continues to move in the direction away from the first lifting mechanism 32, thereby first lowering the rolling mechanism 4 on the second support plate 54, and then away from the sewing mechanism 2; Then, the controller 11 is used to control the second lifting mechanism to lower and hide the sewing mechanism 2. Specifically, the first reduction motor 341 drives the first driving wheel 342 to rotate, and the rotating first driving wheel 342 drives the first driven wheel 343 to rotate through the first motion belt. The first driven wheel 343 rotates to drive the rotating seat 346 in the mounting cavity 345 in the fixed seat 344 to rotate with the screw nut 348 in the contact ball bearing 347, thereby driving the first lifting screw rod 321 through which the screw nut 348 and the rotating seat 346 are passed to perform a lifting action, and finally the first support plate 33 arranged on the top of the first lifting screw rod 321 is lifted and lowered, that is, the machine table 21 located on the top of the first support plate 33 descends, so that the sewing machine body 22 will be on the workbench 1, and the sewing machine body 22 is used for sewing processing, thereby improving the utilization rate of the sewing equipment.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
