Description

Technical Field

[0001] The utility model relates to the technical field of garment machinery, in particular to a bobbin support on a garment knitting flat knitting machine. Background Technique

[0002] A flat knitting machine, also known as a flat knitting machine or a horizontal knitting machine, is a kind of knitting machine, specifically referring to a horizontal knitting machine. It uses a horizontal knitting needle bed for knitting and is a double-needle plate latch needle weft knitting machine. The flat knitting machine plays an important role in the textile industry. It can efficiently produce knitted fabrics of various styles and structures and is widely used in industries such as clothing, home textiles, sports equipment, and automotive interiors.

[0003] When a flat knitting machine is in use, it is necessary to fix the bobbin through a bobbin support and then feed the yarn for knitting. In the current existing technology, since the bobbin support and the bobbin are only simply fixed, when feeding the yarn, the bobbin rotates under the traction of the yarn tension. Driven by inertia, the rotation angle of the bobbin is too large, making the yarn relatively loose during the yarn feeding process, easily resulting in situations such as the yarn being entangled and knotted, which is not convenient for the use of the bobbin support. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a bobbin support on a garment knitting flat knitting machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A bobbin support on a garment knitting flat knitting machine, including a base, a clamping assembly is installed above the base. The clamping assembly includes a fixed seat, the lower surface of the fixed seat is fixedly connected to the upper surface of the base, a movable groove is opened on the side surface of the fixed seat, a screw rod is movably connected inside the movable groove, a movable block is threadedly connected to the outer surface of the screw rod, a pressing wheel is movably connected to the side surface of the movable block, a roller is movably connected to the side surface of the fixed seat, a fixed column is fixedly connected to the side surface of the fixed seat, and a mounting block is fixedly connected to the outer surface of the fixed column.

[0006] As a further description of the above technical scheme:

[0007] One end of the screw rod passes through the inside of the movable groove and extends to the outside of the fixed seat, a turning handle is fixedly connected to one end of the screw rod, the number of the rollers is two, and the two rollers are mirror-symmetrical along the horizontal central axis of the pressing wheel.

[0008] As a further description of the above technical scheme:

[0009] A rotating block is movably connected inside the base, and a rotating disk is fixedly connected to the upper surface of the rotating block.

[0010] As a further description of the above technical solution:

[0011] A positioning column is fixedly connected to the upper surface of the rotating disk. The number of the positioning columns is two, and fixing blocks are fixedly connected to the upper surfaces of the two positioning columns.

[0012] As a further description of the above technical solution:

[0013] A cylinder is fixedly connected to the upper surface of the base. The number of the cylinders is two, and the two cylinders are mirror-symmetrical along the horizontal central axis of the base.

[0014] As a further description of the above technical solution:

[0015] An output shaft of the cylinder is fixedly connected with a lifting plate. A through hole is formed in the upper surface of the lifting plate, and the outer surface of the fixing block is movably connected to the inside of the through hole.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, for the bobbin holder on a garment knitting flat knitting machine, the yarn is passed upward from below through between the roller and the pressing wheel by the clamping assembly, and then the turning handle is rotated to make the screw rotate, driving the movable block to move in the movable groove. The pressing wheel is driven to approach the roller, clamping the yarn between the roller and the pressing wheel, and then the yarn is wound around the fixed column and separated by the mounting block so that the yarn does not contact on the fixed column. In the current existing technology, since the connection between the bobbin holder and the bobbin is only simple fixation, when feeding the yarn, the bobbin rotates under the traction of the pulling force of the yarn. Driven by inertia, the rotation angle of the bobbin is too large, making the yarn relatively loose during the yarn feeding process, easily causing situations such as the yarn being entangled and knotted, which is not convenient for using the bobbin holder. For the bobbin holder on a garment knitting flat knitting machine, it can clamp the yarn, so that the yarn will not be affected by the inertia of the bobbin during the yarn feeding process, keeping the yarn in a taut state, avoiding situations such as entanglement and knotting, and facilitating the use of the bobbin holder.

[0018] 2. Compared with the prior art, for the bobbin holder on a garment knitting flat knitting machine, through the rotating block, rotating disk, positioning column, fixing block, cylinder, lifting plate and through hole, the bobbin is inserted on the positioning column, and then the rotating disk is rotated to turn the bobbin to a position close to the fixed seat. Then the cylinder is controlled to descend, driving the lifting plate to descend, so that the fixing block is inserted into the through hole to limit and fix the positioning column, and thus the yarn feeding operation can be carried out. The positioning column far from the fixed seat that is vacated can place the next bobbin, which can be used to quickly replace the used bobbin, facilitating the replacement of the bobbin and improving the replacement efficiency.
