Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a simple-to-install triangular template for a computer flat knitting machine. Background Technology

[0002] As a core piece of equipment in the knitting industry, the computerized flat knitting machine's triangular template is a key component that controls the movement trajectory of the knitting needles, determines knitting accuracy and efficiency, and directly affects the fabric's forming quality and production stability. With the diversification, high precision, and complex patterns of knitted fabrics, the market has placed higher demands on the knitting adaptability, stitch control accuracy, and ease of adjustment of computerized flat knitting machines.

[0003] The existing multi-segment needle selection computer flat knitting machine cam templates have gradually revealed many shortcomings in practical applications. Firstly, the return needle cam, as the core component controlling the accuracy of needle return, is mostly fixed with a single bolt, which cannot achieve flexible adjustment of the movement trajectory. When different patterns or fabric types need to be knitted, different specifications of return needle cams must be disassembled and replaced, which is not only cumbersome and time-consuming to adjust, but also increases the cost of spare parts inventory. Although some improved structures attempt to use arc-shaped grooves, the positioning stability at both ends of the return needle cam is insufficient, and it is prone to shaking during high-speed knitting, leading to needle return deviations and causing quality problems such as missed needles and incorrect needles.

[0004] Secondly, the connection structure between the needle guide cam and the base plate is mostly rigid or simple sliding fit. Adjusting the tilt angle of the needle guide cam is difficult, making it hard to accurately adapt to different yarn thicknesses, materials, and weaving densities. This results in poor stitch uniformity and affects the smoothness of the fabric surface. Meanwhile, the needle guide cam, as a key component guiding the needle's rise and fall, often has a planar contact with the needle turner cam, leading to high sliding resistance and severe wear. Prolonged use can cause jamming, reducing the equipment's lifespan and operational stability. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a computer flat knitting machine triangular template that is easy to install, which can effectively solve the problems in the existing technology.

[0006] This utility model provides a simple-to-install triangular template for a computer flat knitting machine, including a base plate, a turning triangle, a platen, a measuring triangle, an upper guard, a middle guard, and a lower guard. The turning triangle, platen, measuring triangle, upper guard, middle guard, and lower guard are all set on the base plate. The base plate has multiple sets of preset holes and arc-shaped grooves. A returning triangle is set on the outer side of the arc-shaped groove. One end of the returning triangle is locked to the preset hole by a connecting bolt, and the bottom of the other end of the returning triangle is movably set in the arc-shaped groove by a connecting bolt.

[0007] Furthermore, the base plate has inclined grooves on both sides and a vertical groove in the middle. The bottom end of the angle triangle is integrally fixed with a lower fixing strip, which is inserted into the inclined groove.

[0008] Furthermore, the bottom end of the disc mountain is set in the vertical groove by connecting bolts, and the bottom end of the disc mountain has a concave flange structure. The disc mountain is slidably set on the outer flange of the flip-pin triangle.

[0009] Furthermore, the bottom of the lower retaining wall has notches on both sides, and a return guide block is inserted in the notch. The return guide block is fixed to the base plate. The middle part of the lower retaining wall is a hollow structure, and a push pin triangle is fixed in the hollow structure. The middle part of the push pin triangle is connected and fixed to a preset hole on the base plate by a connecting bolt.

[0010] Furthermore, the upper and lower ends of the return-needle triangles on both sides are respectively located between the upper and middle protective hills, the top of the middle protective hill is provided with a notch, and the bottom of the return-needle triangle is located in the notch.

[0011] Furthermore, two sets of connecting holes are provided in the middle of the return triangles on both sides.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: one end of the return needle triangle is locked and fixed to the pre-drilled hole in the base plate by a connecting bolt, while the other end is movably set in the arc-shaped groove, forming an adjustable structure of "one end fixed, one end sliding". This design allows the return needle triangle to flexibly adjust its tilt angle and position along the trajectory of the arc-shaped groove, adapting to the needle return requirements of different patterns and fabric varieties without changing parts. It provides a simple connection and adjustment function, significantly shortens the debugging cycle, and reduces inventory costs.

[0013] In this device, inclined grooves are formed on both sides of the base plate, and the stitch cam is inserted into them through an integrally formed lower fixing strip at the bottom. This allows the stitch cam to slide stably along the inclined grooves, enabling precise fine-tuning of the tilt angle. The stitch size can be flexibly adjusted according to the yarn thickness, material, and weaving density requirements, ensuring uniform stitches on the fabric surface and improving the fabric's forming quality. The bottom of the disc slids onto the outer flange of the turning cam using a concave flange structure, optimizing the contact form of the mating surfaces, reducing sliding resistance and wear rate. Simultaneously, the disc slid is set in the central vertical groove via connecting bolts, allowing for flexible adjustment of its vertical position, further broadening the adaptability range of weaving processes.

[0017] 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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: A simple-to-install triangular template for a computerized flat knitting machine, see attached diagram. Figure 1 -Appendix Figure 3 It includes a base plate 1, a flip-pin triangle 2, a disc mountain 3, a measuring triangle 4, an upper guard mountain 5, a middle guard mountain 6, and a lower guard mountain 8. The flip-pin triangle 2, disc mountain 3, measuring triangle 4, upper guard mountain 5, middle guard mountain 6, and lower guard mountain 8 are all set on the base plate 1. The base plate 1 has multiple sets of preset holes 104 and arc grooves 102. A return-pin triangle 7 is set on the outside of the arc groove 102. One end of the return-pin triangle 7 is locked and fixed to the preset hole 104 by a connecting bolt 72. The bottom of the other end of the return-pin triangle 7 is movably set in the arc groove 102 by a connecting bolt 72.

[0020] The base plate 1 has inclined grooves 101 on both sides and a vertical groove 103 in the middle. The bottom end of the needle-returning triangle 4 is integrally fixed with a lower fixing strip 41, which is inserted into the inclined groove 101. The upper and lower ends of the needle-returning triangles 7 on both sides are respectively limited between the upper guard 5 and the middle guard 6. The notch at the top of the middle guard 6 forms a precise limit on the bottom end of the needle-returning triangle 7, creating a "three-dimensional limiting" structure. This effectively restricts the radial sway of the needle-returning triangle 7. Even if slight wear occurs after long-term use, the gap can be finely adjusted with bolts, extending the service life of the components. The two sets of connecting holes 71 in the middle of the needle-returning triangle 7 allow for different bolt fixing positions to be selected according to actual stress requirements, enhancing the load-bearing capacity of the structure and adapting to high-speed, heavy-duty weaving scenarios, enabling continuous operation of the equipment.

[0021] The bottom of the disc mountain 3 is set in the vertical groove 103 by connecting bolt 72, and the bottom of the disc mountain 3 has a concave flange structure. The disc mountain 3 is slidably set on the outer flange of the turning cam 2. The bottom of the lower guard mountain 8 has notches on both sides, and a return guide block 10 is locked in the notch. The return guide block 10 is fixed on the base plate 1. The middle part of the lower guard mountain 8 is a hollow structure. The lower guard mountain 8 adopts a hollow structure, and the push cam 9 is integrated and fixed in the hollow structure. It is directly fixed to the preset hole 104 of the base plate 1 by the middle connecting bolt 72, which simplifies the assembly structure and makes the positioning of the push cam 9 more stable, and there is no jamming phenomenon when running at high speed. At the same time, it is not necessary to disassemble the lower guard mountain 8 as a whole during disassembly and maintenance. Only the middle bolt needs to be loosened to complete the disassembly and assembly of the push cam 9. The notches on both sides of the bottom of the lower guard mountain 8 and the return guide block 10 are engaged to form a double positioning structure, which further improves the return accuracy and running stability of the lower guard mountain 8 and avoids positioning deviation during high-speed knitting.

[0022] The hollow structure houses a pusher cam 9, the middle of which is connected and fixed to a pre-drilled hole 104 on the base plate 1 via a connecting bolt 72. Slanted grooves 101 are formed on both sides of the base plate 1, into which the stitch gauge cam 4 is inserted via an integrally formed lower fixing strip 41. This allows the stitch gauge cam 4 to slide stably along the slanted grooves 101, enabling precise fine-tuning of the tilt angle. This allows for flexible adjustment of the stitch size according to yarn thickness, material, and weaving density requirements, ensuring uniform stitches on the fabric surface and improving fabric quality. The bottom of the disc cam 3 uses a concave flange structure to slide on the outer flange of the turn-up cam 2, optimizing the contact form of the mating surfaces, reducing sliding resistance and wear rate. Simultaneously, the disc cam 3 is set within the central vertical groove 103 via connecting bolts 72, allowing for flexible adjustment of its vertical position and further expanding the adaptability of weaving processes.

[0023] The upper and lower ends of the two return-to-needle triangles 7 are respectively positioned between the upper guard plate 5 and the middle guard plate 6. A notch is formed at the top of the middle guard plate 6, and the bottom of the return-to-needle triangle 7 is positioned within the notch. Two sets of connecting holes 71 are formed in the middle of each of the two return-to-needle triangles 7. One end of the return-to-needle triangle 7 is locked to the pre-drilled hole 104 in the base plate 1 by a connecting bolt 72, while the bottom of the other end is movably positioned within the arc-shaped groove 102, forming an adjustable structure of "one end fixed, one end sliding". This design allows the return-to-needle triangle 7 to flexibly adjust its tilt angle and position along the trajectory of the arc-shaped groove 102, adapting to the needle return-to-needle requirements of different patterns and fabric types without the need to replace parts, significantly shortening the debugging cycle and reducing inventory costs. Simultaneously, the bolt positioning method at both ends ensures the stability of the return-to-needle triangle 7 during high-speed knitting, effectively avoiding problems such as missed needles and misaligned needles caused by shaking.

[0024] 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.
