Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a quilting machine. Background Technology

[0002] A quilting machine is a textile machine used to sew linear patterns on mattresses, bedspreads, or quilts, and its principle is similar to that of a sewing machine. A quilting machine includes a work platform and a quilting head. The quilting head includes a pressure plate that holds the product and a needle holder with several quilting needles. The transmission system of the quilting machine includes a pressure plate drive shaft connected to the pressure plate, a quilting drive shaft connected to the needle holder, and a main shaft connected to a power source. The main shaft drives the pressure plate drive shaft and the quilting drive shaft to rotate through a transmission mechanism. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a transmission mechanism for driving the pressure plate drive shaft and the quilting drive shaft of a quilting machine.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quilting machine transmission mechanism, including a first swing mechanism, a second swing mechanism, a third swing mechanism and a central shaft, wherein the quilting transmission shaft is connected to the main shaft through the first swing mechanism, and the pressure plate transmission shaft is connected to the main shaft through the third swing mechanism, the central shaft and the second swing mechanism; the central shaft is parallel to the pressure plate transmission shaft, the third swing mechanism connects the pressure plate transmission shaft and the central shaft, and the second swing mechanism connects the central shaft and the main shaft.

[0005] According to the above technical solution, the main shaft rotates, driving the quilting drive shaft through the first swing mechanism, and driving the pressure plate drive shaft through the second swing mechanism, the central shaft, and the third swing mechanism. In this way, the main shaft simultaneously and separately drives both the quilting drive shaft and the pressure plate drive shaft. Compared to the method where the main shaft drives the quilting drive shaft / pressure plate drive shaft, and then the quilting drive shaft / pressure plate drive shaft drives the pressure plate drive shaft / quilting drive shaft, this method improves transmission efficiency and accuracy.

[0006] As a structural arrangement, the quilting drive shaft, the pressure plate drive shaft, and the central shaft are pivotally connected to the bearing supports. The bearing supports are mounted on the frame of the quilting machine head. The first swing mechanism is located on the right side of a pair of bearing supports, the second swing mechanism is located between a pair of bearing supports, and the third swing mechanism is located on the left side of a pair of bearing supports.

[0007] The second swing mechanism includes a second cam mounted on the main shaft, a second connecting rod cooperating with the second cam, and a second swing member connected to the second connecting rod. The second swing member is fixedly mounted on the central shaft and has a slotted hole. The second swing member is connected to the second connecting rod through the slotted hole and a fastening bolt fitted therein. Loosening the fastening bolt allows adjustment of its position in the slotted hole, thereby adjusting the swing amplitude of the second swing member driven by the second connecting rod. After adjustment, the nut is tightened to secure the fastening bolt.

[0008] The second connecting rod has a large end component at one end and a small end component at the other end. A second cam component engages with the large end component, and a second swing component connects to the small end component. Both the large and small end components are screwed to the second connecting rod. The second cam component and the large end component are pivotally connected, and the second cam component is mounted on the main shaft. A bearing is provided in the small end component, and the fastening bolt engages with the bearing, thus achieving a hinged connection between the small end component and the second swing component. By rotating the second connecting rod, the operator can adjust the relative positions of the second connecting rod, the large end component, and the small end component, thereby adjusting the overall length of the second connecting rod, the large end component, and the small end component, and thus adjusting the starting swing angle of the second swing component.

[0009] The third swing mechanism includes a third connecting rod, a third main swing member hinged to the third connecting rod, and a third secondary swing member hinged to the third connecting rod. The third main swing member is fixedly installed at one end of the central rotating shaft, and the third secondary swing member is fixedly installed on the pressure plate drive shaft. The third main swing member is provided with a fastening hole, in which a fastening screw is screwed. The fastening screw abuts against the central rotating shaft, fixing the third main swing member to the central rotating shaft.

[0010] The third main component has a swing arm, and one end of the third connecting rod is hinged to the swing arm. When the angle between the swing arm and the third connecting rod is zero degrees, the pressure plate driven by the pressure plate drive shaft moves to the lowest position and presses the product. In this way, the pressure plate can stably press the product.

[0011] The third oscillating component has a slotted hole, and it is connected to the third connecting rod via a fastening bolt that fits into the slotted hole. Loosening the fastening bolt allows adjustment of its position within the slotted hole, thereby adjusting the oscillation amplitude of the third oscillating component driven by the third connecting rod. After adjustment, tighten the nut to secure the fastening bolt.

[0012] This invention enables the main shaft to simultaneously and separately drive the quilting drive shaft and the pressure plate drive shaft, thereby improving transmission efficiency and accuracy. Furthermore, the structural design of the third main component allows the pressure plate to stably press the product. Attached Figure Description
