Description

Technical Field

[0001] This utility model belongs to the field of long-hair machine accessories, and relates to an improved horn for use in long-hair machines. Background Technology

[0002] The long-pile knitting machine is a type of weft knitting machine, and the bevel is one of its accessories. The bevel's needle-facing surface is machined with various shapes of guide needle grooves by a CNC machine tool. The bevel is used to guide the running trajectory of the knitting needle. Different shaped guide needle grooves on the bevel's needle-facing surface allow the knitting needle to knit a variety of long-pile fabrics. Currently, because the bevels used in long-pile knitting machines are fastened to the saddle or other support bases with screws, the height of the guide needles cannot be flexibly adjusted. Maintenance personnel can only disassemble the bevel and repeatedly re-drill screw holes on the saddle or other support bases, which is time-consuming and laborious. Summary of the Invention

[0003] In order to solve the problems existing in the background technology, this utility model provides an improved horn-shaped tool that can flexibly adjust the height of the guide needle when used in a long-hair machine.

[0004] To achieve the above objectives, the technical measures of this utility model are as follows: an improved knitting needle guide block is applied to a long-pile knitting machine. The front side of the knitting needle guide block serves as the needle-welding surface, and a rearwardly recessed needle guide groove is machined on the needle-welding surface. A vertical groove is machined in the middle of the rear side of the knitting needle guide block. The knitting needle guide block is machined with a screw hole, which extends rearward through the vertical groove. The feature is that it also includes a cuboid locking block and a vertical traction screw. Two cuboid locking blocks are embedded in the vertical groove on the rear side of the knitting needle guide block and are fixedly positioned by screws. A screw-in hole is machined in the middle of the top edge of the knitting needle guide block, and the lower end of the vertical traction screw can be screwed downward into the screw-in hole.

[0005] Furthermore, the cube-shaped locking block is composed of a hollow square shell, pressing teeth, and a spring. The rear side of the hollow square shell is open, and a rod hole is integrally formed on both the left and right sides of the hollow square shell. Each rod hole corresponds to a pressing tooth. A limiting piece is integrally formed on the inner end of each pressing tooth. The left end of the spring is sleeved with the inner end of the pressing tooth on the left side, and the right end of the spring is sleeved with the inner end of the pressing tooth on the right side. The spring simultaneously presses against the two pressing teeth on the left and right sides.

[0006] This invention is mounted on a saddle, which serves as a guide and support platform for the lifting / lowering movement of the invention. The advantage of this invention is that it allows for flexible adjustment of the guide pin height. Attached Figure Description

[0007] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0008] Figure 1 This is a front perspective view of the overall assembly structure of this utility model;

[0009] Figure 2 for Figure 1 The right view;

[0010] Figure 3 This is a rear vertical section view of the square-shaped carding block of this utility model. Detailed Implementation

[0011] Figure 1 , Figure 2 An improved knitting needle guide block 1 is shown, which serves as the needle-welding surface on the front side of the needle guide block 1. A needle-welding groove 11 with a rearward indentation is machined on the needle-welding surface by a CNC machine tool. A vertical groove 12 is machined on the middle of the rear side of the needle guide block 1 by a CNC machine tool. A screw hole 13 is machined on the needle guide block 1 by a CNC machine tool. The screw hole 13 extends rearward to the vertical groove 12. The invention is characterized by further including a cuboid locking block A and a vertical traction screw B. The upper and lower cuboid locking blocks A are embedded in the vertical groove 12 on the rear side of the needle guide block 1 and are fixedly positioned by screws. A screw-in hole is machined on the middle of the top edge of the needle guide block 1 by a CNC machine tool. The lower end of the vertical traction screw B can be screwed downward into the screw-in hole.

[0012] like Figure 3 As shown, the cuboid locking block A is composed of a hollow cuboid shell A1, a pressing tooth A2, and a spring A3. The rear side of the hollow cuboid shell A1 is open, and a rod hole is integrally formed on both the left and right sides of the hollow cuboid shell A1. Each rod hole corresponds to a pressing tooth A2. The inner end of each pressing tooth A2 is integrally formed with a limiting piece A21. The diameter of the limiting piece A21 is larger than the diameter of the rod hole. The left end of the spring A3 is sleeved with the inner end of the pressing tooth on the left side, and the right end of the spring A3 is sleeved with the inner end of the pressing tooth on the right side. The spring A3 simultaneously presses against the two pressing teeth A2 on the left and right sides.

[0013] This utility model is used in conjunction with a saddle. In this utility model, the vertical traction screw B can pass through the guide hole on the saddle and can be positioned by screwing in a nut. The vertical traction screw B can pull the knitting needle guide block 1 and the cuboid locking block A to move up and down at the same time. During the operation, the top pressing tooth A2 in the cuboid locking block A can finally mesh with the corresponding guide tooth on the saddle under the top pressing action of the spring A3.
