Technical Field
[0001] This utility model belongs to the field of sock machine technology, and specifically relates to a toothed needle disc device for sock machines. Background Technology
[0002] Existing integrated sock knitting machines use toothed needles (also called transfer needles) to transfer fabric or socks from the needle cylinder of the knitting equipment. A common problem is that when these toothed needles are damaged and need replacement, multiple parts and the needle plate from which they were installed must be removed. Each replacement requires repositioning the toothed needles and the needle cylinder, making maintenance cumbersome. Inaccurate positioning can lead to machine malfunctions and the production of defective socks. Improving the ease of toothed needle replacement is a subject of research for those skilled in the art.
[0003] In addition, the existing gear needle disk has an extremely complex drive structure during rotation, and how to improve the convenience of the drive structure is also a research object of those skilled in the art. Utility Model Content
[0004] This invention provides a simple and convenient toothed needle disc device for sock machines.
[0005] A sock knitting machine needle plate device includes a needle plate comprising a first semi-circular toothed disc assembly and a second semi-circular toothed disc assembly. Both the first and second semi-circular toothed disc assemblies include a semi-circular needle plate. An mounting ring is installed on the upper side of the semi-circular needle plate. A vertical needle groove is provided on the outer circumference of the semi-circular needle plate, and a slot is provided laterally within the needle groove. A toothed needle is inserted into the needle groove. A protrusion is provided on the inner side of the toothed needle, engaging with the slot. An elastic body is provided on the outer side of the toothed needle, and an outer pressure plate is provided on the outer side of the elastic body. The outer pressure plate connects to the semi-circular needle plate, and an inclined surface is provided on the inner side of the outer pressure plate to engage with the toothed needle. With this invention, the toothed needle can be easily removed from the needle plate by pushing it outwards along the inclined surface to disengage the protrusion from the slot. Installing a new toothed needle is also simple: insert the toothed needle into the inner side of the elastic body, press it against the outer pressure plate, and allow the protrusion to engage with the slot. This makes installation and removal convenient.
[0006] The needle grooves are two or more evenly arranged on the outer circumference of the semi-circular needle plate, so that the slots are arranged in a semi-circular manner. The elastic body is a spring or rubber band, and the elastic body is a semi-circular elastic compression sleeve needle.
[0007] The semi-circular needle plate is divided into a first semi-circular needle plate and a second semi-circular needle plate, which are connected by a rotating arm. The first semi-circular needle plate has a pin hole on its outer periphery.
[0008] The top of the first semi-circular needle plate is connected to a first mounting base, and the outer periphery of the first mounting base is connected to a first outer pressure tile. The inner wall of the first outer pressure tile is provided with a first groove and a first inclined surface. The outer wall of the first semi-circular needle plate is provided with a first arc groove and a first slot. A gap is provided between the first arc groove and the first groove, and a first elastic body is clamped together in the gap.

The back of the U-shaped needle groove is provided with a third inclined surface to facilitate the manual movement of the toothed needle to disengage it from or to engage it with the needle groove.
[0012] The pin hole is connected to a needle plate rotation drive device that drives the first semi-circular needle plate to rotate around the rotating arm. The needle plate rotation drive device includes a locking rod, which is on the same axis as the pin hole. The locking rod moves back and forth to engage with the pin hole. The needle plate rotation drive device also includes a rotary cylinder, which is connected to a drive block via a drive rod. The drive block is connected to a moving plate, and the moving plate is equipped with a motor base. The motor base is connected to a rotary motor, which drives the locking rod to rotate, thereby driving the first semi-circular needle plate to rotate around the rotating arm to align the toe of the sock, which can then be used with a sewing machine for sewing.
[0013] The end of the main shaft of the rotary motor is a worm gear, which is connected to a worm. The worm is connected to a locking rod through a turntable. The worm gear and the worm gear increase the torque of the locking rod rotation and increase the reliability of the first semi-circular needle plate rotation drive.
[0014] This utility model of a sock machine needle plate device shortens the installation and maintenance time of the needle plate by using a toggle-type installation and disassembly of the needle plate. Attached Figure Description

Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 12 The specific implementation method further illustrates the technical solution of this patent.
[0031] like Figure 1 The device shown as Embodiment 1 is a toothed needle disc device for a sock knitting machine, comprising a toothed needle disc, a first semi-circular toothed disc assembly 31, and a second semi-circular toothed disc assembly 32. Both the first and second semi-circular toothed disc assemblies 31 and 32 include a semi-circular needle disc. An mounting ring 30 is installed on the upper side of the semi-circular needle disc. A vertical needle groove 44 is provided on the outer circumference of the semi-circular needle disc, and a slot is provided laterally within the needle groove. The needle groove is embedded in the mounting toothed needle 51. The side is provided with a protrusion 53, which engages with a slot. The outer side of the toothed pin 51 is provided with an elastic body, and the outer side of the elastic body is provided with an outer pressure tile. The outer pressure tile is connected to a semi-circular pin plate. The inner side of the outer pressure tile is provided with an inclined surface that engages with the toothed pin 51. The toothed pin 51 moves outward to engage the inclined surface, causing the protrusion 53 to disengage from the slot, thereby separating the toothed pin 51 from the semi-circular pin plate. This allows the damaged toothed pin 51 to be removed. The installation of the toothed pin 51 can be completed by simply reversing the operation. The overall operation is convenient and simple.
[0032] Example 2 is a preferred structural design. Figure 2 , Figure 3 , Figure 8To improve the installation accuracy and ease of the toothed pin 51 relative to the needle groove 44, two or more needle grooves 44 are evenly arranged on the outer circumference of the semi-circular needle plate, resulting in a semi-circular arrangement of the grooves. The elastic body is a spring or rubber band, which elastically presses the toothed pin 51 in a semi-circular shape, thereby enabling the quick installation of the toothed pin 51 into the needle groove 44. The semi-circular needle plate is divided into a first semi-circular needle plate 4 and a second semi-circular needle plate 72, which are connected by a rotating arm 310. The first semi-circular needle plate 4 has a pin hole 80 on its outer circumference.
[0033] Example 3 Figure 4 ,like Figure 9 ,like Figure 10 To achieve the rotational performance of the first semi-circular needle disc 4, a needle disc rotation drive device 91, which drives the first semi-circular needle disc 4 to rotate around the rotating arm 310, is connected to the pin hole 80. The needle disc rotation drive device 91 includes a locking rod 90, which is on the same axis as the pin hole 80. The locking rod 90 moves back and forth to engage with the pin hole 80. The needle disc rotation drive device 91 also includes a rotary cylinder 97, which is connected to a drive block 95 via a drive rod 96. The drive block 95 is connected to a moving plate 99, and a motor base 94 is mounted on the moving plate 99. The motor base 94 is connected to a rotary motor 92, which drives the locking rod 90 to rotate. The end of the main shaft of the rotary motor 92 is a worm gear 98, which is connected to a worm 100. The worm 100 is connected to the locking rod 90 via a turntable 89. The needle plate rotation drive device 91 drives the locking rod 90 to rotate via the rotary motor 92, thereby enabling the first semi-circular needle plate 4 to rotate around the rotating arm 310 to complete the closure of the sock toe, which is used in conjunction with the sewing machine 93 for automatic sock toe sewing.
[0034] Example 4 Figure 3As another specific technical structure for replacing the toothed pin 51, the top of the first semi-circular pin disk 4 is connected to a first mounting base 300, and the outer periphery of the first mounting base 300 is connected to a first outer pressure plate 301. The inner wall of the first outer pressure plate 301 is provided with a first groove 312 and a first inclined surface 303. The outer wall of the first semi-circular pin disk 4 is respectively provided with a first arc groove 43 and a first slot 41. A gap 66 is provided between the first arc groove 43 and the first groove 312, and a first elastic body 7 is clamped in the gap 66. The toothed pin 51 is embedded between the first elastic body 7 and the first semi-circular pin disk 4. The top of the second semi-circular needle plate 72 is connected to a second mounting base 309. A second outer pressure plate 305 is connected to the outer periphery of the second mounting base 309. The inner wall of the second outer pressure plate 305 has a second groove and a second inclined surface. The outer wall of the second semi-circular needle plate 72 has a second arc groove and a second slot, respectively. A gap exists between the second arc groove and the second groove, which together clamps the second elastic body 6. A toothed needle 51 is embedded between the second elastic body 6 and the second semi-circular needle plate 72. When the toothed needle 51 is damaged, simply move it outwards to disengage the protrusion 53 of the toothed needle from the first groove 312 or the second groove, and then pull the toothed needle 51 out. The reverse operation allows the toothed needle 51 to be installed into the toothed needle plate. Replacing the toothed needle 51 does not require removing any other parts.
[0035] Example 5 Figure 2 As shown, in order to realize the function of picking up and transferring socks, a lifting device for the toothed needle plate is installed on the inner side of the mounting ring 30. The lifting device includes an annular cylinder seat 9. The cylinder seat 9 is driven by compressed air to lift and lower the push rod 71. The push rod passes through and connects the first mounting base 300 and the first semi-circular needle plate 4, and is connected to the first semi-circular needle plate 4 through the connecting plate 8, so that the first semi-circular needle plate 4 is controlled by the push rod 71. The second semi-circular needle plate 72 is provided with a guide shaft 81 that lifts and lowers synchronously with the first semi-circular needle plate 4.
[0036] Example 6 Figure 6 ,like Figure 7 As shown in the diagram, the toothed needle 51 has a fourth inclined surface 54 at its top, a U-shaped needle groove 52 at its bottom, a second inclined surface 56 at the bottom of the U-shaped needle groove 52, and a third inclined surface 55 on its back. The fourth inclined surface 54, the second inclined surface 56, and the third inclined surface 55 facilitate the installation and removal of the toothed needle 51 and improve the stability of the knitting needle.
[0037] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
