Description

Technical Field

[0001] This utility model relates to the field of knitting equipment technology, specifically to a combined sinking triangle. Background Technology

[0002] Computerized flat knitting machines are double-needle plate needle weft knitting machines with high automation and intelligence. They are widely used in the knitting industry. The Sink device is mainly used to move the sinker to assist the knitting process.

[0003] For example, Chinese patent application CN211446090U discloses a signal triangle device for a computerized flat knitting machine, including a signal mother plate, a signal triangle, and a drive mechanism. The signal mother plate has multiple sets of guide grooves, each set of guide grooves including a first guide groove and a second guide groove. The upper ends of the first guide groove and the upper ends of the second guide groove extend obliquely towards each other at an angle of 40-60 degrees. The signal triangle is located on the front of the signal mother plate, and the back of the signal triangle has a guide wheel, which engages with the first guide groove or the second guide groove. The drive mechanism is located on the back of the signal mother plate and has a drive surface that supports the guide wheel. The drive surface, in conjunction with the guide grooves, drives the signal triangle to move obliquely.

[0004] However, when using the signal triangle device of this computerized flat knitting machine, the signal triangle is made of a single piece of material, which is labor-intensive and material-intensive, and it is easy to deform after heat treatment. When dealing with different needle types, the entire signal triangle needs to be disassembled and replaced, which is costly and inefficient.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0033] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 The combined settlement triangle includes the Sink mother plate 1, the settlement triangle component 2, and the control component 3;

[0034] The control component 3 is installed at the rear end of the motherboard 1;

[0035] The settlement triangle assembly 2 can be provided in any number. The settlement triangle assembly 2 includes a combined left triangle component 21 for controlling the running trajectory of the signal needle heel on the left, a combined right triangle component 22 for controlling the running trajectory of the signal needle heel on the right, and a limiting sliding component 23 for limiting the running trajectory of the combined left triangle component 21 and the combined right triangle component 22.

The combined left triangle component 21 is connected to the combined right triangle component 22, and the limiting sliding component 23 is connected to the combined left triangle component 21, the combined right triangle component 22 and the control assembly 3.

[0036] When the combined settling triangle is in normal use, the control component 3 controls the up and down movement of the combined left triangle component 21 and the combined right triangle component 22, so that the signal needle heel runs along the trajectory formed between the combined left triangle component 21 and the combined right triangle component 22, thereby achieving the function of controlling the signal indentation depth. The lower boss one 213 and the lower boss two 223 can be replaced to adapt to the working conditions of different needle types. The detachable setting of the lower boss one 213 and the lower boss two 223 allows for adaptive replacement according to different needle types, reducing the amount of processing, saving materials, and making it suitable for batch and standardized production.

[0037] The combined left triangular component 21 includes a left base plate 211, an upper boss 212, a connecting plate 214, and a first detachable limiting structure. The first detachable limiting structure consists of a lower boss 213 and a limiting plate 215. The left base plate 211 is slidably mounted on the front end of the mother plate 1. The rear end of the left base plate 211 is connected to the limiting sliding component 23. The connecting plate 214 and the upper boss 212 are sequentially fixed to the upper front end of the left base plate 211 from back to front by bolts. The limiting plate 215 and the lower boss 213 are sequentially fixed to the lower front end of the left base plate 211 from back to front by bolts. The lower boss 213 is connected to the combined right triangular component 22.

[0038] The upper boss 212 and the connecting plate 214 are inverted trapezoidal, and the lower boss 213 is trapezoidal. The width of the lower boss 213 is greater than the width of the upper boss 212. The left end of the limiting plate 215 is arranged to gradually tilt to the right from bottom to top in coordination with the lower boss 213.

[0039] The combined right triangular component 22 includes a right base plate 221, an upper boss 222, a connecting plate 224, and a second detachable limiting structure. The second detachable limiting structure consists of a lower boss 223 and a limiting plate 225. The right base plate 221 is slidably mounted on the front end of the motherboard 1. The rear end of the right base plate 221 is connected to the limiting sliding component 23. The connecting plate 224 and the upper boss 222 are sequentially fixed to the upper side of the front end of the right base plate 221 from back to front by bolts. The lower boss 223 and the limiting plate 225 are sequentially fixed to the lower side of the front end of the right base plate 221 from back to front by bolts. The left front end of the lower boss 223 is slidably connected to the lower boss 213.

[0040] The upper boss 222 and the connecting plate 224 are inverted trapezoidal, and the lower boss 223 is trapezoidal. The width of the lower boss 223 is greater than the width of the upper boss 222. The right end of the limiting plate 225 is gradually tilted to the left from bottom to top in coordination with the lower boss 223.

[0041] The combined right triangular component 22 also includes an extension plate 226. The extension plate 226 is located on the rear left side of the lower boss 223 and is fixedly connected to the right base plate 221 and the lower boss 223. The extension plate 226 is in contact with the mother plate 1 and the left base plate 211 and is slidably connected.

[0042] Two limiting sliding components 23 are provided. The two limiting sliding components 23 are respectively installed at the rear ends of the left base plate 211 and the right base plate 221. The limiting sliding component 23 includes a sliding structure 231 and a sliding rod 232. The sliding structure 231 is provided at the rear ends of the left base plate 211 and the right base plate 221 for limiting the upper and lower sliding of the left base plate 211 and the right base plate 221. The sliding rod 232 is respectively fixedly installed at the rear ends of the left base plate 211 and the right base plate 221 and connected to the control component 3.

[0043] The sliding structure 231 consists of a slider and a slide rail. The sliders of the two sliding structures 231 are fixedly installed at the rear ends of the left base plate 211 and the right base plate 221, respectively, and the slide rails of the two sliding structures 231 are fixedly installed at the front end of the Xinke motherboard 1.

[0044] The control component 3 includes a control board 31, which is slidably connected to the rear end of the motherboard 1. The control board 31 has a groove 32 that is fitted with a slide rod 232. The groove 32 is divided into three sections: left, middle, and right. The left and right sections of the groove 32 are symmetrically arranged at both ends of the middle section and are smoothly connected to the middle section. The ends of the left and right sections that are away from the middle section are gradually inclined upwards. The slide rod 232 is located inside the groove 32 and is slidably connected to the control board 31. One end of the control board 31 is connected to the drive device. The movement direction of the control board 31 is set to the left and right.

[0045] When the combined settlement triangle is in normal use, the drive device is activated, which moves the control plate 31 left and right. The movement of the control plate 31 causes the slide rod 232 to slide along the inclined groove 32. The slide rod 232 causes the left base plate 211 and the right base plate 221 to slide up and down along the mother plate 1 under the action of the sliding structure 231. The left base plate 211 sequentially moves the upper boss 212, the lower boss 213, the connecting plate 214, and the limiting plate 215. The right base plate 221 sequentially moves the upper boss 222 and the lower boss 223. Connecting plate 224, limiting plate 225, and extension plate 226 move. When the signal is required to be inactive, upper boss 1 212 and upper boss 222 are aligned. At this time, the signal pin heel passes between upper boss 1 212 and lower boss 1 213, and between upper boss 222 and lower boss 223. The signal is inactive. When the equipment moves the signal motherboard 1 to the left, the signal pin heel moves to the right relative to the signal motherboard 1. The control board 31 controls the left base plate 211 to move upward and the right base plate 221 to move downward, and the signal pin heel moves. When the device moves, it first contacts the lower boss 213 and moves upward, then contacts the upper boss 222 and moves downward, thus controlling the pressing depth of the signal pin. When the device moves the signal motherboard 1 to the right, the signal pin heel moves to the left relative to the signal motherboard 1. The control board 31 controls the left substrate 211 to move downward and the right substrate 221 to move upward. When the signal pin heel moves, it first contacts the lower boss 223 and moves upward, then contacts the upper boss 212 and moves downward, thus controlling the signal. The detachable design of the lower boss 213 and the lower boss 223 facilitates the adjustment of the signal pin depth. The needle type is compatible, and there is no need to replace the entire sinker triangle assembly 2. The extension plate 226 is designed so that when the extension plate 226 moves upward, it can move the dust between the left base plate 211, the lower boss 1 213 and the limiting plate 1 215 upward, which is easy to clean. The wider lower boss 1 213 and lower boss 223 extend the time from when the needle heel contacts the lower boss 1 213 and moves upward to when it contacts the upper boss 222 and moves downward to stop pressing the needle. The same applies when moving in the opposite direction, which is of great help in knitting special patterns.

[0046] Example 2: In some embodiments, such as Figure 6 and Figure 7 As shown in the preferred embodiment of this utility model, two limiting sliding components 23 are provided. The two limiting sliding components 23 are respectively installed at the rear ends of the left base plate 211 and the right base plate 221. The limiting sliding component 23 includes a sliding structure 231, a sliding rod 232 and a spring 233. The sliding structure 231 is provided at the rear ends of the left base plate 211 and the right base plate 221 for limiting the upper and lower sliding of the left base plate 211 and the right base plate 221. The sliding rod 232 is respectively fixedly installed at the rear ends of the left base plate 211 and the right base plate 221 and connected to the control component 3. One end of the spring 233 is fixedly connected to the sliding rod 232, and the other end of the spring 233 is fixedly connected to the mother plate 1.

[0047] The sliding structure 231 consists of a slider and a slide rail. The sliders of the two sliding structures 231 are fixedly installed at the rear ends of the left base plate 211 and the right base plate 221, respectively, and the slide rails of the two sliding structures 231 are fixedly installed at the front end of the Xinke motherboard 1.

[0048] The control component 3 includes a control board 31, which is slidably connected to the rear end of the motherboard 1. The control board 31 has a groove 32 that is fitted with a slide rod 232. The groove 32 is divided into three sections: left, middle, and right. The left and right sections of the groove 32 are symmetrically arranged at both ends of the middle section and are smoothly connected to the middle section. The ends of the left and right sections that are away from the middle section are gradually inclined upwards. The upper end of the groove 32 is inclined, and the lower end of the groove 32 is open. The slide rod 232 is located inside the groove 32 and is slidably connected to the control board 31. One end of the control board 31 is connected to the drive device, and the movement direction of the control board 31 is set to left and right.

[0049] When the combined sinker triangle is in normal use, when the sinker heel contacts the lower boss 213 or the lower boss 223 and applies a large force, the lower boss 213 or the lower boss 223 drives the corresponding slide bar 232 to move downward to compress the spring 233, thereby reducing the vertical stroke of the sinker heel and reducing the force of the sinker heel on the yarn loop. By controlling the elasticity of the elastic support, the damage to the loop caused by excessive pressure and the missed needle caused by insufficient sinker stroke can be effectively reduced. The pressure state of the sinker on the loop can be maintained to meet the requirements of the sinker for knitting and reduce the holes and missed needles in the garment.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
