Description

Technical Field

[0001] This utility model relates to the field of bed sheet and duvet cover processing technology, and in particular to an automatic sewing device for bed sheets and duvet covers. Background Technology

[0002] During the processing of bed sheets and duvet covers, they need to be sewn together. However, existing sewing devices are not convenient for automatically conveying bed sheets and duvet covers. In the current technology, bed sheets and duvet covers often need to be moved manually, which reduces the working efficiency of the device. Utility Model Content

[0003] The purpose of this invention is to provide an automatic sewing device for bed sheets and duvet covers to solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is an automatic sewing device for bed sheets and duvet covers, including a sewing machine. The sewing machine has grooves on both the front and rear sides near the bottom. Sliding blocks are movably connected in the grooves. A connecting plate is fixedly connected to the side of the sliding block away from the sewing machine.

[0005] In one embodiment, each of the connecting plates has several through slots, and L-shaped plates are fixedly connected to both the left and right sides of the connecting plates. Each of the L-shaped plates has through holes. A motor is provided at the bottom of the connecting plate near the left side. The power output shaft of each motor is fixedly connected to a transmission rod. The right end of the transmission rod passes through two adjacent through holes and is fixedly connected to a fixing plate.

[0006] In one embodiment, a plurality of rollers are fixedly connected to the outer edge of each transmission rod, and the rollers are located in adjacent through grooves.

[0007] In one embodiment, each connecting plate is provided with a limiting plate at its top, and two horizontal plates are fixedly connected to the left and right sides of each limiting plate, and two fixing plates are fixedly connected to the left and right sides of each connecting plate.

[0008] In one embodiment, each of the fixed plates has a threaded hole, and each of the horizontal plates has a threaded rod inserted into its bottom. The bottom end of the threaded rod passes through the adjacent threaded hole and is threadedly connected to it.

[0009] In one embodiment, a spring is fitted on the outer edge of the threaded rod near the top, the top of the spring is fixedly connected to the bottom of the horizontal plate, and the bottom of the spring is fixedly connected to the top of the fixed plate.

[0010] In one embodiment, a plurality of the rollers are arranged linearly from left to right.

[0011] The beneficial effects provided by this utility model are:

[0012] Through the cooperation of the sewing machine, motor, rollers, and limiting plate, the connecting plate can move left and right. The connecting plate drives the slider to move, and the slider moves on the sewing machine. The bed sheet and duvet cover are placed between the connecting plate and the limiting plate. The motor is started, and the motor drives the transmission rod to rotate. The transmission rod drives the fixed plate to rotate, and the transmission rod drives the roller to rotate. The roller conveys the bed sheet and duvet cover, and the sewing machine begins to sew the bed sheet and duvet cover. When it is necessary to clamp the bed sheet and duvet cover, the threaded rod is rotated. The threaded rod drives the limiting plate to move downward, and the spring is compressed. The limiting plate then cooperates with the roller to clamp the bed sheet and duvet cover. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The technical solutions of the present invention will be further described below with reference to the accompanying drawings of the embodiments. The present invention is not limited to the specific embodiments described below.

[0022] It should be understood that the same or similar reference numerals in the accompanying drawings of the embodiments correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "front," "rear," "left," "right," "top," and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0023] In one embodiment, such as Figure 1-7 As shown, an automatic sewing device for bed sheets and duvet covers includes a sewing machine 1. The sewing machine 1 has grooves on both the front and rear sides near the bottom. Slider 3 is movably connected in each groove. A connecting plate 2 is fixedly connected to the side of the slider 3 away from the sewing machine 1. Several through grooves are opened on the connecting plate 2. L-shaped plates 9 are fixedly connected to the left and right sides of the connecting plate 2. Through holes are opened on the L-shaped plates 9. A motor 4 is provided at the bottom of the connecting plate 2 near the left side. The power output shaft of the motor 4 is fixedly connected to a transmission rod 5. The right end of the transmission rod 5 passes through two adjacent through holes and is fixedly connected to a fixing plate 6.

[0024] Several rollers 7 are fixedly connected to the outer edge of the transmission rod 5. The rollers 7 are located in adjacent through slots. The top of the connecting plate 2 is provided with a limiting plate 8. Two horizontal plates 10 are fixedly connected to the left and right sides of the limiting plate 8. Two fixing plates 13 are fixedly connected to the left and right sides of the connecting plate 2. Threaded holes are opened on the fixing plates 13. Threaded rods 11 are inserted into the bottom of the horizontal plates 10. The bottom end of the threaded rods 11 passes through the adjacent threaded holes and is threadedly connected to them. A spring 12 is sleeved on the outer edge of the threaded rod 11 near the top. The top of the spring 12 is fixedly connected to the bottom of the horizontal plate 10, and the bottom end of the spring 12 is fixedly connected to the top of the fixing plate 13. Several rollers 7 are arranged linearly from left to right.

[0025] Working principle: The connecting plate 2 moves left and right, which drives the slider 3 to move. The slider 3 moves on the sewing machine 1, placing the bed sheet and duvet cover between the connecting plate 2 and the limiting plate 8. The motor 4 is started, which drives the transmission rod 5 to rotate. The transmission rod 5 drives the fixed plate 6 to rotate, which drives the roller 7 to rotate. The roller 7 conveys the bed sheet and duvet cover, and the sewing machine 1 begins to sew the bed sheet and duvet cover. When it is necessary to clamp the bed sheet and duvet cover, the threaded rod 11 is rotated. The threaded rod 11 drives the limiting plate 8 to move downward, and the spring 12 is compressed. The limiting plate 8 then cooperates with the roller 7 to clamp the bed sheet and duvet cover.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
