Description

Technical Field

[0001] The invention relates to the technical field of hosiery knitting machines, in particular to a thread pressing device of a computer hosiery knitting machine. Background Art

[0002] A hosiery machine is a knitting machine for producing socks. The main feature of the hosiery machine is that it can weave bag-shaped sock heels and toes in two directions. The hosiery circular machine is mainly composed of a yarn feeding mechanism, a weaving mechanism, a needle selection mechanism, a control mechanism, a transmission mechanism, a density adjustment mechanism and a pulling mechanism. The thread pressing device is a mechanism that clamps and fixes the yarn to prevent the yarn from deviating.

[0003] However, the existing computer hosiery machine's thread pressing device usually adopts an integrated structural design. When pressing the yarn, the yarn needs to be passed through the inside of the thread pressing device one by one, which increases the operator's workload. At the same time, it is impossible to achieve the operation of compacting and straightening the yarn one by one, reducing the use effect of the thread pressing device. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a thread pressing device for a computerized hosiery knitting machine.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a thread pressing device of a computer hosiery knitting machine, comprising a mounting frame, five pads are equidistantly welded on the upper surface of the mounting frame, and the upper surfaces of the five pads are all welded with a lower clamping plate, the inner wall of the lower clamping plate is welded with a wire rubbing plate, and the upper surface of the wire rubbing plate is equidistantly provided with wire rubbing grooves, an air guide pipe is connected through the inside of the wire rubbing plate, and the air guide pipe is connected to a cold air hood pasted on the inner wall of the wire rubbing groove, hanging brackets are symmetrically welded on both sides of the upper surface of the mounting frame, and a cross plate is connected through the inner wall of the hanging bracket, a threaded rod is equidistantly rotatably connected inside the cross plate, a handle is welded on the top of the threaded rod, and the bottom of the threaded rod is rotatably connected to the upper clamping plate through a sleeved bearing sleeve.

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

[0007] The side cross-sections of the lower clamping plate and the upper clamping plate are both semicircular structures, and the inner and outer diameters of the lower clamping plate and the upper clamping plate are consistent.

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

[0011] Blocks are symmetrically arranged at the edges of the opening ends on both sides of the upper clamping plate.

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

[0013] The cross section of the hanging rack is an inverted L-shaped structure, and the lower surface of the horizontal end thereof is provided with an arc-shaped hanging groove.

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

[0015] The inner surfaces of the lower clamping plate and the upper clamping plate are both embedded with rubber gaskets, and the thickness of the rubber gaskets is one third of the thickness of the lower clamping plate and the upper clamping plate.

[0016] Beneficial Effects

[0017] The present invention provides a thread pressing device for a computer hosiery knitting machine, which has the following beneficial effects:

[0018] (1): The thread pressing device is provided with a split symmetrical upper clamping plate and a lower clamping plate, so that the upper and lower clamping plates can form a complete cylindrical clamping mechanism under the connection of the clamping block and the clamping groove, thereby playing a large-scale anti-drop clamping protection role for the yarn. At the same time, in conjunction with the arc-shaped thread smoothing groove in the thread smoothing plate, the yarn can be independently pressed, so that the yarn can be completely fixed in the clamping mechanism, preventing the thread pressing from shaking or deflecting during socks knitting, thereby improving the safety of yarn knitting.

[0019] (2): The wire pressing device is provided with an air guide pipe, which is connected to a refrigeration pipe to guide low-temperature gas into the cold air hood, thereby cooling the inner surface wall of the wire drawing groove, preventing the yarn from generating high temperature heat after long-term contact with the wire drawing groove and causing the yarn to break, thereby enhancing the use effect of the wire pressing device.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-4 A thread pressing device for a computer hosiery knitting machine comprises a mounting frame 1, five pads 2 are welded at equal intervals on the upper surface of the mounting frame 1, and a lower clamping plate 3 is welded on the upper surface of the five pads 2, a threading plate 31 is welded on the inner surface wall of the lower clamping plate 3, and threading grooves 33 are opened at equal intervals on the upper surface of the threading plate 31, an air guide 34 is connected through the inside of the threading plate 31, and the air guide 34 is connected with a cold air cover 35 pasted on the inner surface wall of the threading groove 33, hanging frames 4 are welded symmetrically on both sides of the upper surface of the mounting frame 1, and a horizontal plate 9 is connected through the inner surface wall of the hanging frame 4, a threaded rod 8 is rotatably connected inside the horizontal plate 9, a handle 7 is welded on the top of the threaded rod 8, and the bottom of the threaded rod 8 is rotatably connected to the upper clamping plate 6 through a sleeved bearing sleeve 61.

[0028] The side cross-sections of the lower splint 3 and the upper splint 6 are both semicircular structures, and the inner and outer diameters of the lower splint 3 and the upper splint 6 are consistent. The edges of the open ends of the lower splint 3 on both sides are symmetrically provided with card grooves 32, and the edges of the open ends of the upper splint 6 on both sides are symmetrically provided with card blocks 63, so that when the upper splint 6 and the lower splint 3 are closed, the card blocks 63 will be embedded in the card grooves 32 and fixed, thereby achieving a complete connection effect between the upper splint 6 and the lower splint 3. The cross-section of the hanger 4 is an inverted L-shaped structure, and the lower surface of the horizontal end thereof is provided with an arc-shaped hanging groove 5. The inner walls of the lower splint 3 and the upper splint 6 are both embedded with rubber gaskets 62, and the thickness of the rubber gasket 62 is one-third of the thickness of the lower splint 3 and the upper splint 6. When the yarn accidentally touches the inner wall of the upper splint 6 or the lower splint 3, the friction between the two can be reduced to prevent the yarn from breaking.

[0029] Working principle: When in use, the horizontal end of the hanger 4 is installed at the working position of the hosiery machine through the hanging groove 5, the position of the mounting frame 1 is fixed, and the yarns for hosiery are classified one by one, so that the yarns are evenly embedded in the wire drawing groove 33 and fixed to ensure the independence of the yarns, and then the handle 7 is turned counterclockwise to drive the threaded rod 8 to rotate in the cross plate 9, thereby pushing the upper clamping plate 6 to move downward, and the upper clamping plate 6 and the lower clamping plate 3 are clamped and fixed by the clamping block 63 and the clamping groove 32, so that the upper clamping plate 6 and the lower clamping plate 3 form a complete tubular clamping mechanism, which has a protective effect on preventing the yarn from falling off and pressing the wire. When the yarn moves for a long time, heat will be generated. At this time, the air guide pipe 34 is externally connected to the refrigeration pipe, and the low-temperature gas is introduced into the air guide pipe 34, and evenly conducted in the cold air hood 35, which has the effect of absorbing heat and cooling the heat on the surface of the wire drawing groove 33, protecting the yarn from breaking. Then the wire pressing device is fully used.
