Description

Technical Field

[0001] The utility model relates to the technical field of quilting machines, and specifically relates to a circular knife thread cutting machine base for a quilting machine. Background Technique

[0002] A quilting machine is a textile machine that sews a textile with a sandwich using a long needle to fix internal materials such as cotton wadding, etc., so as to enhance the structure and beauty of the textile under the guidance of a linear pattern. This kind of machine is especially suitable for making textiles that need to increase thickness and strength while maintaining beauty, such as household items like mattresses, bedspreads, and quilts. The textiles made by quilting are not only more durable but also can provide a more comfortable sleeping experience.

[0003] At present, when the quilting machine is running, due to the large openness of its own structure, it is easy to have an angular difference during thread cutting, reducing the success rate of one-time cutting. At the same time, it is impossible to provide limit protection for the fixed knife, greatly reducing the cutting accuracy.

[0004] Therefore, a new circular knife thread cutting machine base for a quilting machine is proposed to solve the above problems. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A circular knife thread cutting machine base for a quilting machine, including a base, a fixed frame is fixedly connected to the right side of the top of the base, and a limit component with strong protection is arranged above the base;

[0007] The limit component includes a limit arc frame, a connecting frame is fixedly connected to the top of the side wall of the fixed frame, a groove is opened on the left side of the connecting frame, a fixed rod is fixedly connected between the front end and the rear end inside the groove of the connecting frame, and the right side of the limit arc frame is fixedly connected to the outside of the fixed rod;

[0008] Preferably, the limit arc frame is inclined and bent downward to the left, a fixed knife is fixedly connected to the bottom of the limit arc frame and the connecting frame, and the bottom of the fixed knife is arc-shaped.

[0009] Preferably, two groups of support plates are fixedly connected to the side wall of the fixed frame, a rotating rod is movably connected between the outsides of the two groups of support plates, an auxiliary runner is fixedly connected to the outside of the rotating rod, a cylinder is fixedly connected to the bottom outside the fixed frame, and a push rod is fixedly connected to the side wall of the cylinder and penetrates through the inside of the fixed frame.

[0010] Preferably, a first connecting rod is fixedly connected to the top end of the auxiliary runner, a moving knife is fixedly connected to the top end of the first connecting rod, a second connecting rod is fixedly connected to the bottom end of the auxiliary runner, an external connecting rod is fixedly connected to the front end of the bottom of the second connecting rod, a socket is fixedly connected to the side wall of the external connecting rod, and the side wall of the socket is fixedly connected to the side wall of the push rod.

[0011] Preferably, two sets of connecting seats are fixedly connected to the front end and the rear end of the bottom of the base respectively. An installation bolt is vertically penetrated through the inside of the connecting seat, and a knob is fixedly connected to the top end of the installation bolt.

[0012] Preferably, a mounting seat is fixedly connected to the side wall of the connecting seat. A reinforcing bottom plate is arranged between the two sets of connecting seats. The two sides of the reinforcing bottom plate are inserted and connected inside the mounting seat, and an adhesive bottom layer is fixedly connected to the bottom end of the reinforcing bottom plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The circular knife wire cutting machine base for the quilting machine not only realizes the limit fixing function, the support and protection function, but also realizes the assembly and combination function;

[0014] (1) By providing a connecting frame, a limiting arc frame, a fixed knife and a fixing rod, the limiting arc frame is sleeved and installed outside the fixing rod and is located in the groove on the side wall of the connecting frame. By utilizing the characteristic that the limiting arc frame is inclined and bent downward to the left, limit protection is provided for the fixed knife, ensuring the accuracy of the operation of the moving knife, enabling rapid and accurate shearing. At the same time, the fixing property between the fixed knife and the connecting frame is enhanced, effectively preventing the fixed knife from shaking or even falling off after long-term use, and strengthening the structural safety;

[0015] (2) By providing a support plate, an auxiliary runner, a rotating rod, a first connecting rod, a second connecting rod and an external connecting rod, the external connecting rod and the push rod are fixed together through the socket. The cylinder and the push rod cooperate with each other to push the external connecting rod outwards. By utilizing the mobility of the auxiliary runner, the moving knife is rotated within a small range. The two support plates play a role in limiting and protecting the two ends of the auxiliary runner, and the auxiliary runner is supported and fixed by the rotating rod to ensure the firmness of the auxiliary runner itself, avoiding the equipment from malfunctioning due to the falling off of the auxiliary runner, and optimizing the connectivity between the structures;

[0016] (3) By providing a connecting seat, an installation bolt, a reinforcing bottom plate, an adhesive bottom layer, a mounting seat and a knob, the base is placed on the surface of the equipment. By rotating and moving downward the multiple installation bolts, the base is fixed in all directions to ensure the fixity of the overall structure. At the same time, the adhesive property of the contact surface is enhanced by the adhesive bottom layer to improve the adhesive force and avoid the displacement of the base and the reduction of the stability. The bearing capacity between the two sets of connecting seats is enhanced by the reinforcing bottom plate to prevent the installation bolt from moving up and down inside the connecting seat for a long time, resulting in depression or even fracture, and improving the firmness.
