Description

Technical Field

[0001] This utility model belongs to the technical field of mattress processing equipment, specifically relating to a double-headed edge-locking device for mattress processing. Background Technology

[0002] An overlock sewing machine, also known as a binding machine or edging machine, is an industrial sewing machine that uses one or more threads to form a chain stitch for hemming. Its main purpose is to prevent pilling at the seams of garments. In current technology, rollers are usually installed at the bottom of the overlock sewing machine for easy movement and handling. Overlock sewing machines are commonly used in the clothing and furniture industries to hem edges, and have become an essential part of mattress production. A mattress is an item placed between the human body and the bed for health and comfortable sleep. Mattresses are made of a variety of materials, and different materials provide different sleep experiences. Mattress production involves multiple processes, including cutting, filling, quilting, slitting, overlocking, quality inspection, and packaging.

[0003] Existing double-headed edge-locking devices for mattress processing allow for easy movement or fixation relative to the ground by rotating and adjusting the support components, thus meeting different usage needs and providing convenience. However, they cannot fix the mattress in place; furthermore, they cannot store excess fabric at the edge during use, reducing convenience. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a double-headed locking device for mattress processing, which features both mattress fixing and fabric roll-up capabilities.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-headed edge-locking device for mattress processing, comprising a support, a limiting mechanism provided at the upper outer side of the support, a mattress body provided at the top of the support, a roller assembly provided at the bottom of the support, a winding mechanism provided at the lower side of the support, and an edge-sewing machine provided around the top of the support.

[0006] The limiting mechanism includes a U-shaped frame, a hydraulic cylinder is fixedly connected to the top of the U-shaped frame, a pressure plate is provided at the bottom of the hydraulic cylinder, and a sliding component is provided at the lower side of the U-shaped frame.

[0007] Preferably, the sliding assembly includes an electric slide rail, one side of which is fixedly connected to a bracket, and a sliding frame is provided on the outer side of the electric slide rail, one side of which is fixedly connected to a U-shaped frame.

[0008] Preferably, a reinforcing rib is fixedly connected to the side of the sliding frame located below the U-shaped frame.

[0009] Preferably, a protrusion is fixedly connected to the bottom of the pressure plate.

[0010] Preferably, the winding mechanism includes a connecting frame, a rotating rod rotatably connected to one side of the connecting frame, a turntable fixedly connected to one side of the rotating rod, a collecting roller disposed on the side of the turntable away from the rotating rod, a screw fixedly connected to the outer side of the collecting roller, and a nut disposed on the outer side of the screw.

[0011] Preferably, a slot is provided on one side of the turntable, and a plug is fixedly connected to the side of the collecting roller near the slot.

[0012] Preferably, the outer side of the collecting roller is provided with Velcro.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a limiting mechanism. The hydraulic cylinder drives the pressure plate from the top of the U-shaped frame downwards, thereby pressing the pressure plate down to fix the mattress. The electric slide rail drives the sliding frame to move back and forth, thereby allowing the hydraulic cylinder to move above the support, so that the pressure plate can always be aligned with the mattress body. The reinforcing rib can strengthen the connection between the U-shaped frame and the sliding frame. The protrusion contacts the mattress body, which can increase friction and improve the fixing effect. By driving the pressure plate down through the hydraulic cylinder, the mattress body can remain stable when sealing the edges.

[0015] 2. This utility model is equipped with a winding mechanism. One end of the connecting frame is connected to the bracket. The rotating rod can rotate inside the connecting frame. The collecting roller is inserted between two turntables. The screw is inserted into the groove on the turntable. At the same time, the nut is screwed into the screw and tightened to fix the collecting roller. When the rotating rod is rotated, the collecting roller will rotate together. After the collecting roller is inserted into the turntable, the insert block will also be inserted into the slot to strengthen the connection between the collecting roller and the turntable. Velcro can be used to attach the fabric strip so that the collecting roller can wrap the fabric strip when it rotates. By rotating the rotating rod, the collecting roller can collect the fabric strip. The fabric strip can be removed by unscrewing the nut. Attached Figure Description
