Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 11 The present invention provides a technical solution: a double-disc counting scale, comprising a saddle 1, and a slider 15 is slidably connected to the back of the saddle 1. A lifting groove 12 is provided on the back of the saddle 1, which is arranged vertically, and protruding slide rails 13 are integrally connected along the vertical direction on both sides of the groove body, and the cross section is a rectangular structure; the slider 15 is a rectangular strip rod, and a slide groove 16 is provided on both sides. The slider 15 is slidably inserted into the lifting groove 12, and the slide rail 13 is slidably connected and matched with the slide groove 16, which is used to limit the guide slider 15 to stably move in the lifting groove 12.

[0021] It should be noted that the position of the slider 15 on the saddle 1 can be controlled to adjust the needle height and needle pressing depth of the circular knitting machine. The above is the prior art and will not be explained in detail.

[0022] On the front side of the saddle 1, the adjusting rod 3 is driven to extend and retract through the thread of the turntable 15, and the conical surface of the adjusting rod 3 slides against the conical groove 22 in the middle of the slider 15 to push the slider 15 to move up and down; the turntable 15 is embedded with a transmission sleeve 4, and the adjusting rod 3 is clamped inside the transmission sleeve 4 and rotates synchronously, and the transmission sleeve 4 drives the turntable 2 6 to rotate through the gear differential; the turntable 2 6 is slidably nested with the turntable 1 5, and scales are arranged in a ring shape on the front side to count the rotation of the double discs.

[0023] The adjusting rod 3 drives the slider 15 to move. Specific description: The transmission sleeve 4 is a cylindrical structure with a diamond-shaped rotation groove 401 in the center, and a through hole 402 connected to the rotation groove 401 is also provided at the end of the transmission sleeve 4; a rotation groove 7 is provided on the front of the saddle 1, and the transmission sleeve 4 is slidably inserted in the rotation groove 7, and a threaded hole 2 connected to the lifting groove 12 is also provided on the bottom surface of the rotation groove 7; in this embodiment, the adjusting rod 3 includes a threaded rod 301, and the tail end of the threaded rod 301 is integrally connected with a tapered rod 302, and the head of the threaded rod 301 is integrally connected with a bolt head 303, which is a diamond-shaped structure and has a strip groove 304 along the axial direction; the bolt head 303 is slidably engaged in the rotation groove 401, and the rod section of the adjusting rod 3 close to the bolt head 303 is sleeved with a spring four 28, and the spring four 28 is located in the rotation groove 401; the threaded rod 301 passes through the through hole 402 and is threadedly connected to the threaded hole 2, and the tapered rod 302 passes through the threaded hole 2 and contacts the tapered groove 22.

[0024] When in use, the turntable 5 is twisted to drive the transmission sleeve 4 to rotate synchronously. The transmission sleeve 4 uses the internal rotation groove 7 and the bolt head 303 to engage, and synchronously drives the entire adjustment rod 3 to rotate accordingly, driving the threaded rod 301 to telescopically move in the threaded hole 2 of the saddle 1, so that the tapered rod 302 presses against the tapered groove 22 of the slider 15, and the tapered rod 302 moves along the inner arc surface of the tapered groove 22, pushing the slider 15 to move along the lifting groove 12 on the back of the saddle 1, thereby completing the movement and adjustment of the slider 15 efficiently and stably.

[0025] Among them, the spring 28 in the transmission sleeve 4 reduces the shaking of the adjustment rod 3 under the action of elastic force, and maintains the stability of the movement of the adjustment rod 3.

[0026] It should be noted that the conical rod 302 presses the conical groove 22 of the slider 15 to move the slider 15, which is a mature technology of existing equipment.

[0027] As a further improvement of this embodiment, in order to maintain the stability of the slider 15 during its movement: A spring groove 20 is provided at the bottom of the slider 15, and a spring 21 is inserted into the spring groove 20. The bottom of the spring 21 contacts the bottom surface of the lifting groove 12. During the process, the spring 21 is in a compressed state, supporting the slider 15 to move up and down without shaking or deviating. Furthermore, a mounting hole 17 is provided on the slider 15, and a fixing bolt 18 is threadedly installed on the mounting hole 17.

The slider 15 is supported by two springs in the moving direction, and the groove 14 is used to limit the movement of the fixing bolt 18, which acts on the slider 15 to limit the movement, so as to avoid excessive movement affecting the knitting effect.

[0028] In order to facilitate the double-disc rotation counting, in this embodiment, the transmission sleeve 4 is provided with a step groove 1 26 and a step groove 2 27 from the outside to the inside, the turntable 1 5 and the turntable 2 6 are slidably sleeved on the step groove 1 26 in sequence, the turntable 1 5 is fastened by bolts, and a gear ring 29 is fixedly connected to one side of the turntable 2 6. The inner wall of the gear ring 29 is attached to the wall surface of the step groove 1 26. A rotation groove 2 8 is provided at the end of the rotation groove 1 7. The turntable 2 6 fits in the rotation groove 2 8, exposing the turntable 1 5 on the outside, and the turntable 2 6 is locked in position by the turntable 1 5 on the outside, so that two counting turntables with the same axis are presented on the front of the saddle 1; The second step groove 27 is integrally connected with a rotating tooth 34, which is an arc-shaped structure; A rotating groove 3 9 is formed on the bottom surface of the rotating groove 2 8. A transmission member 30 is connected to the rotating groove 3 9 through a bearing. The transmission member 30 includes a rotating shaft 31 that is rotatably connected to the bearing. A driving tooth is fixedly connected to the end of the rotating shaft 31. The driving tooth includes a long tooth 33 and a short tooth 32 of different lengths, which are arranged on the rotating shaft 31 at adjacent intervals. The driving teeth mesh with the transmission gear ring 29, and the long teeth 33 mesh with the transmission rotating teeth 34. When the turntable 1 5 on the front of the saddle 1 is twisted, the transmission sleeve 4 is synchronously driven to rotate, and the rotating teeth 34 are driven to rotate, driving the long teeth 33, and then driving the gear ring 29 to drive the turntable 2 6. The number of rotating teeth 34 is preset. After the turntable 1 5 rotates a certain angle, the rotating teeth 34 leave the long teeth 33 and no longer mesh. The driving tooth space of the entire transmission member 30 is not driven facing the stepped groove 27, that is, the rotating teeth 34 mesh with the long teeth 33 after the turntable 1 5 rotates one circle, so that the turntable 2 6 is driven to a limited extent. Under the gear transmission, the entire double disk rotates one circle when the turntable 1 5 rotates one circle, and the turntable 2 6 rotates a large scale.

[0029] The solution of the present application has a large number of double-disc rotations, which improves the defects of single-disc counting, has obvious scales, high adjustable accuracy, low adjustment difficulty, and is easy to use.

[0030] It should be noted that the extension and retraction process of the adjusting rod 3 is designed in coordination with the turntable, which is a conventional technology, and the specific values ​​are not repeated here.

[0031] To facilitate the twist adjustment control of the turntable 5: In this embodiment, one end of the transmission sleeve 4 is annularly arranged with a raised tooth surface 25 with the center as the base point. The teeth of the tooth surface 25 are trapezoidal, the outer end surface is horizontal, and tooth grooves are formed between adjacent teeth. A mounting groove 10 is opened at the bottom of the rotating groove 7, and a spring three 23 is fixedly connected in the groove. One end of the spring three 23 is fixedly connected to the steel ball 24. The steel ball 24 rolls in contact with the tooth surface 25, and the spring three 23 is in a compressed state.

[0032] When the turntable 5 is rotated by one scale, a tooth on the corresponding tooth surface 25 rotates. Initially, the arc surface of the steel ball 24 is stuck in the tooth groove. During the rotation of the tooth surface 25, the tooth rotates, squeezing the steel ball 24. The steel ball 24 shrinks inward along the installation groove 10 until it hits the horizontal surface of the outer end of the tooth. As the tooth rotates, the steel ball 24 begins to approach the side tooth groove, and uses the elastic force of the compression spring to fall into the side tooth groove.

[0033] It should be noted that the saddle 1 is made of stainless steel. When the steel ball 24 is extended and retracted with the rotation and hits different tooth grooves, it will make a rattling sound and has a certain damping to maintain the rotation stability of the turntable 1 5, which is convenient for the user to rotate and adjust.

[0034] In this embodiment, the saddle 1 is provided with an indicator line 11 on the front, which is arranged vertically and located directly above the second turntable 6, pointing to the scale number on the second turntable 6, for adjusting the user's reading.

[0035] For example, if the indicator line 11 points to the number three on the turntable 2 6, the turntable 1 5 has rotated three times. Since the turntable 1 5 and the turntable 2 6 are concentric, the turntable 1 5 is aligned with the scale number of the indicator line 11 at this time, and the adjustment amount can be fully known, which is convenient to use.

[0036] It should be noted that the indicator line 11 is a conventional design method on the circular knitting machine scale adjuster, which can be a slot or a label.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
