Description

Technical Field

[0001] This application relates to the field of sewing technology, and in particular to a segmented zippered duvet cover and pillowcase sewing mechanism. Background Technology

[0002] In modern home textile manufacturing, duvet covers and pillowcases are mass-market consumer goods, making their production efficiency and quality crucial. Professional duvet cover sewing machines are the core equipment for large-scale, standardized production of high-quality duvet covers and a vital step in the duvet cover and pillowcase sewing process. They integrate automation, high efficiency, and precision sewing technology, significantly surpassing the limitations of traditional household sewing machines.

[0003] In common duvet covers and pillowcases, zippers are sewn into the middle, with the zipper length predetermined. This manual sewing process is inefficient. A related technology offers a machine for sewing duvet covers and pillowcases in one piece. This machine sews a half-zipper along the same edge of two layers of fabric, then cuts the fabric, simultaneously cutting off the zipper. The remaining three edges are then sewn closed to form the duvet cover or pillowcase. However, duvet covers or pillowcases produced by this machine have one entire edge as a zipper, which fails to meet the standards of high-end products, thus impacting sales. Utility Model Content

[0004] In order to facilitate the production of duvet covers and pillowcases by integrated sewing machines, the zipper on one side of the duvet cover or pillowcase is located in the middle to meet the standards of high-end products. This application provides a segmented zipper duvet cover and pillowcase sewing mechanism.

[0005] This application provides a segmented zippered duvet cover and pillowcase sewing mechanism, which adopts the following technical solution:

[0006] A segmented zippered duvet cover and pillowcase sewing mechanism includes a sewing machine body for sewing the zipper onto one side of the fabric, a transport mechanism for moving the zipper to the sewing machine body for sewing, and a cutting mechanism for cutting the zipper. The cutting mechanism cuts the zipper after the transport mechanism drives the zipper to slide a certain distance.

[0007] By adopting the above technical solution, when producing duvet covers and pillowcases, the fabric moves on the machine tool. The control system on the duvet cover and pillowcase sewing machine calculates the time required to sew one side. The control system controls the transport mechanism to transport the zipper to the sewing machine body at the appropriate time for sewing. The transport mechanism transports the zipper according to the set parameters. When the length of the zipper transported is required, the cutting mechanism cuts the zipper, so that the zipper is sewn in sections on one side of the fabric. In subsequent processing, another sewing machine is set up to sew the two layers of fabric between the two sections of the zipper together, so that the zipper on the duvet cover or pillowcase produced by the duvet cover and pillowcase sewing machine is located in the middle of one side, meeting the standards of high-end products.

[0008] Optionally, the transport mechanism includes a motor, a conveyor belt, and rollers. The rollers are coaxially arranged at the output end of the motor. It also includes a clamping wheel. The clamping wheel and the rollers are close to each other and clamp the zipper. The motor drives the rollers to rotate, and the rotation of the rollers causes the zipper to slide along the length of the conveyor belt.

[0009] By adopting the above technical solution, the motor drives the roller to rotate, the clamping wheel clamps the zipper with the roller, and the rotation of the roller causes the zipper to slide along the length of the conveyor belt. The motor drives the zipper to be transported.

[0010] Optionally, the shearing mechanism includes two blades, a rotating shaft, and a drive assembly. The two blades are hinged together by the rotating shaft. The two blades rotate close to each other to form a shearing action. The drive assembly drives the two blades to rotate along the rotating shaft to move closer to or further away from each other.

[0011] By adopting the above technical solution, the blade cuts the zipper. The blade cuts through a drive component, which is controlled by a control system, resulting in higher precision in cutting the zipper.

[0012] Optionally, the drive assembly includes two connecting rods and a push source. The two connecting rods are respectively hinged to the end of the blade away from the conveyor belt. The output end of the push source is provided with a rotating shaft. The ends of the two connecting rods away from the blade are both hinged to the rotating shaft. The push source drives the rotating shaft away from or towards the rotating shaft to drive the two connecting rods to rotate, thereby causing the two blades to rotate along the rotating shaft and move closer to or away from it.

[0013] By adopting the above technical solution, the drive source drives the two connecting rods to rotate, and the two blades rotate along the axis to move closer or further away, thereby cutting the zipper. The zipper cutting does not require worker control. The control system controls the drive source to achieve cutting, which is highly automated and precise.

[0014] Optionally, the conveyor belt includes a retention section and a conveying section. One end of the retention section is located on one side of the roller, and the other end of the retention section faces the end of the conveying section. The conveying section is located at the end of the retention section away from the roller. A partition gap is provided between the retention section and the conveying section. Two blades are disposed at the partition gap for cutting. The end of the conveying section away from the retention section is arranged parallel to the sewing part of the sewing machine body.

[0015] By adopting the above technical solution, the blade cuts at the partition gap, and the retention part mainly retains the cut part of the zipper, so that the zipper needs to be manually placed again when it is transported next time, which facilitates the automatic transport of the zipper. The conveying part is mainly used to transport the zipper, and at the same time, it makes the zipper smooth and sewn.

[0016] Optionally, the retention section and the conveying section are hollowed out along the direction of the zipper's movement, and the zipper slides in the hollow section.

[0017] By adopting the above technical solution, the zipper is transported through the hollow space between the storage section and the conveying section, making the zipper slide more stably.

[0018] Optionally, an observation slot is provided on the top surface of the conveying section along the zipper's moving direction. The observation slot is connected to the hollow part of the conveying section and is used to observe the zipper's transport status.

[0019] By adopting the above technical solution, the observation slot is mainly used by staff to observe the status of the zipper during transportation.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The zipper is transported according to the parameters set by the control system. When the length of the zipper is required, the shearing mechanism cuts the zipper, so that the zipper on the duvet cover or pillowcase produced by the duvet cover and pillowcase sewing machine is located in the middle of one side, which meets the standards of high-end products.

[0022] 2. The control system controls the drive source to achieve cutting, with high automation and precision;

[0023] 3. Staff members observe the transport status of the zipper through the observation slot. Attached Figure Description
