Abstract
Description
Technical Field
[0001] This invention relates to the field of knitting equipment technology, and in particular to a graduated scale for a circular knitting machine. Background Technology
[0002] A triangular dial scale for a circular knitting machine is a precision tool that adjusts the position and height of the knitting needles by adjusting the height of the triangle. It achieves precise control mainly through a scale and slider device, and the scale is usually made of stainless steel.
[0003] Common scale adjustment knobs are divided into three types: screw adjustment, spring screw adjustment, and Archimedes adjustment. The first type, screw adjustment, has an integrated adjustment rod and knob design. By rotating the knob, the screw moves the adjustment knob in and out, and the screw presses against the conical surface of the slider, causing the slider and the triangle fixed on the slider to move downward. The second type, spring screw adjustment, moves the built-in adjustment rod in and out, and the screw's conical surface presses against the conical surface of the slider, causing the slider and the triangle fixed on the slider to move downward. The third type, Archimedes adjustment, moves the adjustment knob, and the constant velocity spiral drives the pin on the slider, causing the slider and the triangle fixed on the slider to move downward.
[0004] Each type of adjustment knob has its own advantages and disadvantages. The only difference lies in the production precision, materials, and quality of each brand. However, the adjustment precision of the existing scale is still insufficient, and there is still a possibility of deviation in the position of the knitting needle. Summary of the Invention
[0005] To overcome the technical defects of the existing technology, the present invention provides a graduated dial for a large circular knitting machine with high adjustment accuracy.
[0006] The technical solution adopted in this invention is:
[0007] A graduated dial for a large circular knitting machine includes a dial housing, a slider assembly, a knob assembly, a primary precision control device, several secondary precision control plates, and a mounting device. The slider assembly is slidably mounted on the dial housing. The knob assembly is rotatably mounted on the dial housing and is connected to the slider assembly via a transmission connection. The primary precision control device is slidably mounted on the dial housing. The knob assembly has several circumferentially oriented sound-emitting grooves. The primary precision control device presses against the knob assembly and is adapted to each sound-emitting groove. Each secondary precision control plate is mounted on two adjacent sound-emitting plates. Between the grooves, the side of the secondary precision control plate closest to the primary precision control device is provided with a pushing slope, and the side of the secondary precision control plate away from the primary precision control device is provided with a scale sensing slope. The secondary precision control plate passes through the knob device, and a sensing rod is provided on the side of the secondary precision control plate closest to the scale sensing slope. A reset spring is provided on the secondary precision control plate, and the reset spring pulls the sensing rod toward the scale sensing slope. The reset spring makes the sensing rod fit against the surface of the knob device, and the secondary precision control plate and the sensing rod attract each other. The knob device is provided with several strip-shaped scales that are adapted to the sensing rod.
[0008] Preferably, the slider device includes an adjusting slider and a slider return spring. The adjusting slider is provided with a slider control ramp. The knob device presses against the slider control ramp. The two ends of the slider return spring press against the adjusting slider and the scale housing, respectively.
[0009] Preferably, the knob device includes a dial and a stud, the dial and the stud are integrally formed, the stud is connected to the scale housing by a threaded pair, the secondary precision control plate passes through the dial, and the reset spring causes the sensing rod to fit against the surface of the dial.
[0010] Preferably, the primary precision control device includes a primary precision control slide rod and a primary precision slide rod return spring. The primary precision control slide rod slides along the scale housing, and the primary precision slide rod return spring is installed on the scale housing. The primary precision slide rod return spring pushes the primary precision control slide rod towards the sound-generating groove.
[0011] Preferably, the secondary precision control sheet is a permanent magnet sheet.
[0012] Preferably, the mounting device is a mounting screw.
[0013] Preferably, the tilt angle between the scale sensing ramp and the knob device is 10 to 15 degrees.
[0014] Preferably, the traction force of the reset spring is 0.2N to 0.5N.
[0015] The beneficial effects of this invention are:
[0016] The slider device is slidably mounted on the scale housing. The triangular part of the large circular knitting machine is mounted on the slider device, enabling the raising and lowering of the large circular knitting machine's triangular part. The knob device is rotatably mounted on the scale housing and is connected to the slider device for transmission, enabling the raising and lowering of the slider device. The primary precision control device is slidably mounted on the scale housing. The knob device has several sound-emitting grooves along its circumference. The primary precision control device presses against the knob device and is adapted to each sound-emitting groove. When the knob device is rotated, the primary precision control device strikes the sound-emitting grooves to produce sound. Technicians can judge the rotation angle of the knob device by the number of sounds, and thus immediately know the corresponding adjustment distance of the slider device. On the other hand, the scale housing has a scale, and the knob device has a ring dial. The positional relationship between the ring dial and the scale indicates the angle of rotation of the knob device, thus conveniently controlling the sliding distance of the slider device.
[0017] Each secondary precision control plate is installed between two adjacent sound-emitting grooves. Each secondary precision control plate has a pushing slope on the side closest to the primary precision control device, and a scale-sensing slope on the side furthest from the primary precision control device. The secondary precision control plate passes through the knob device. A sensing rod is located on the side of the secondary precision control plate closest to the scale-sensing slope. A return spring is installed on the secondary precision control plate, pulling the sensing rod towards the scale-sensing slope. The return spring causes the sensing rod to adhere to the surface of the knob device. The secondary precision control plate and the sensing rod attract each other, and the knob device... The device has several strip-shaped scales that fit the sensing rod. Because the scale sensing slope is inclined, when the secondary precision control plate rises, the sensing rod slides along the scale sensing slope under the push of the scale sensing slope, thereby changing its position on the strip-shaped scale. Thus, the angle of rotation of the knob device between the two sound-emitting grooves can be determined by the position of the sensing rod. When the secondary precision control plate falls, the secondary precision control plate and the sensing rod attract each other, so the sensing rod always adheres to the secondary precision control plate, causing the sensing rod to retract along the strip-shaped scale, realizing the reset of the sensing rod and achieving precise control.

[0032] The present invention will be further described below with reference to the accompanying drawings:
[0033] like Figure 1 — Figure 7As shown, this embodiment provides a graduated dial for a large circular knitting machine, including a dial housing 1, a slider device 2, a knob device 3, a primary precision control device 4, several secondary precision control plates 5, and a mounting device 6. The slider device 2 is slidably mounted on the dial housing 1, and the large circular knitting machine's triangular mechanism is mounted on the slider device 2 to achieve the raising and lowering of the triangular mechanism. The knob device 3 is rotatably mounted on the dial housing 1 and is connected to the slider device 2 to achieve the raising and lowering of the slider device 2. The primary precision control device 4 is slidably mounted on the dial housing 1, and the knob device 3 has several sound-emitting grooves along its circumference. 311, the first-level precision control device 4 presses against the knob device 3. The first-level precision control device 4 is adapted to each sound-emitting groove 311. When the knob device 3 is rotated, the first-level precision control device 4 strikes the sound-emitting groove 311 to produce sound. Technicians can judge the rotation angle of the knob device 3 by the number of sounds, and then immediately know the corresponding adjustment distance of the slider device 2. On the other hand, the scale housing 1 is provided with a scale, and the knob device 3 is provided with a ring dial. The positional relationship between the ring dial and the scale indicates the angle of rotation of the knob device 3, and thus conveniently controls the sliding distance of the slider device 2.
[0034] Each secondary precision control piece 5 is installed between two adjacent sound-emitting grooves 311. Each secondary precision control piece 5 has a pushing inclined surface 51 on the side closer to the primary precision control device 4, and a scale sensing inclined surface 52 on the side farther from the primary precision control device 4. The secondary precision control piece 5 passes through the knob device 3. A sensing rod 53 is located on the side of the secondary precision control piece 5 closer to the scale sensing inclined surface 52. A reset spring 54 is provided on the secondary precision control piece 5. The reset spring 54 pulls the sensing rod 53 towards the scale sensing inclined surface 52, causing the sensing rod 53 to adhere to the surface of the knob device 3. The secondary precision control piece 5 and the sensing rod 53 attract each other. The knob device 3 is provided with several strip-shaped scales 33 that are adapted to the sensing rod 53. Since the scale sensing slope 52 has an inclination, when the secondary precision control plate 5 rises, the sensing rod 53 slides along the scale sensing slope 52 under the push of the scale sensing slope 52, thereby changing its position on the strip-shaped scale 33. Thus, the angle of rotation of the knob device 3 between the two sound-emitting grooves 311 can be known by the position of the sensing rod 53. When the secondary precision control plate 5 falls, since the secondary precision control plate 5 and the sensing rod 53 attract each other, the sensing rod 53 always adheres to the secondary precision control plate 5, so that the sensing rod 53 retracts along the strip-shaped scale 33, thereby realizing the reset of the sensing rod 53.
[0035] Specifically, the slider device 2 includes an adjusting slider 21 and a slider return spring 22. The adjusting slider 21 is provided with a slider control inclined surface 211. The knob device 3 presses against the slider control inclined surface 211. The two ends of the slider return spring 22 press against the adjusting slider 21 and the scale housing 1 respectively. The knob device 3 presses against the slider control inclined surface 211 to control the position of the adjusting slider 21. When the knob device 3 is rotated, the adjusting slider 21 rises and falls. The slider return spring 22 drives the adjusting slider 21 to press against the knob device 3 to reset the adjusting slider 21.
[0036] Specifically, the knob device 3 includes a dial 31 and a stud 32. The dial 31 and the stud 32 are integrally set. The stud 32 is connected to the scale housing 1 through a threaded pair. The secondary precision control plate 5 passes through the dial 31. The reset spring 54 causes the sensing rod 53 to fit against the surface of the dial 31. Through the preset scale on the dial 31, the sensing rod 53 changes the position of the dial 31 to sense the angle of rotation of the dial 31.
[0037] Specifically, the first-level precision control device 4 includes a first-level precision control slide rod 41 and a first-level precision slide rod return spring 42. The first-level precision control slide rod 41 slides along the scale housing 1, and the first-level precision slide rod return spring 42 is installed on the scale housing 1. The first-level precision slide rod return spring 42 pushes the first-level precision control slide rod 41 towards the sound-emitting groove 311. When the knob device 3 rotates, each sound-emitting groove 311 emits sound in sequence through the first-level precision control slide rod 41. The first-level precision control slide rod 41 is provided with a push bar 411 that slides along the push slope 51. Thus, the debugging worker can accurately control the rotation angle of the knob device 3 by the number of sounds emitted by the sound-emitting grooves 311, making debugging more convenient.
[0038] Specifically, the secondary precision control plate 5 is a permanent magnet plate, which attracts the sensing rod 53 to approach the secondary precision control plate 5. During the sliding process of the secondary precision control plate 5, the sensing rod 53 is always in contact with the secondary precision control plate 5, so that the sensing rod 53 can change its position on the strip scale 33 in real time during the sliding process of the secondary precision control plate 5. This allows the sensing rod 53 to accurately reflect the position of the secondary precision control plate 5, and thus accurately sense the rotation angle of the knob device 3.
[0039] Specifically, the mounting device 6 is a mounting screw, which enables the scale housing 1 to be mounted on the large circular knitting machine.
[0040] Specifically, the tilt angle between the scale sensing slope 52 and the knob device 3 is 10 to 15 degrees, which makes it easy for the sensing rod 53 to fit against the strip scale 33 on the knob device 3, ensuring accurate indication.
[0041] Specifically, the traction force of the reset spring 54 is 0.2N to 0.5N, so as to avoid the excessive tension of the reset spring 54 from increasing the friction between the sensing rod 53 and the knob device 3, and to facilitate the contact between the sensing rod 53 and the knob device 3 by attraction.
