Description

Technical Field

[0001] This utility model relates to the field of weaving machine production technology, and in particular to a quick yarn guide for weaving machines. Background Technology

[0002] In the field of textile machinery, the traditional yarn guide design requires the yarn to pass through the through holes at both ends of the yarn guide during installation. This piercing operation severely restricts the yarn installation efficiency and directly affects the production efficiency of the loom.

[0003] 1. The threading process is cumbersome and time-consuming. Traditional yarn guides lack a guiding design in their opening structure, requiring workers to align them precisely for threading, with each threading operation taking 15-20 seconds. Statistics show that each loom performs more than 50 threading operations per day, resulting in a 12% loss of effective working time.

[0004] 2. Missing anti-retrograde structure increases repetitive work. Because no anti-loosening structure is installed, the yarn easily comes off the limiting hole when the equipment vibrates. Production data shows that there are 8-10 downtimes per 10,000 meters of fabric due to yarn falling off, and each reset takes more than 3 minutes.

[0005] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a quick yarn loading guide for looms, making it more valuable for industrial use. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a quick yarn guide for a weaving machine.

[0007] This utility model discloses a quick yarn guide for a weaving machine, including a connecting bracket, a horizontally placed connecting plate at the upper end of the connecting bracket, and baffles at both ends of the connecting plate. Each baffle has an opening on one side for yarn to pass through, and the opening extends to the center of the baffle to have a circular yarn limiting hole. The upper end of the connecting plate has a vertical mounting post, and two pressure plates are fitted on the mounting post.

[0008] This loom uses a quick-load yarn guide, whose connecting bracket supports the overall structure. The connecting plate is horizontally fixed to the upper end of the connecting bracket, and the baffle is set at both ends of the connecting plate. The opening is located on the side of the baffle for the yarn to pass through and extend to the center of the yarn limiting hole. The mounting column is vertically fixed to the upper end of the connecting plate and is equipped with two movable pressure plates. All components work together to achieve quick yarn loading and stable guidance.

[0009] Furthermore, the outer edge of each tablet is turned outwards, and the two tablets are set back to back, forming a guide groove for the wire clamping between the turned-out edges of the two tablets.

[0010] This yarn guide achieves efficient guiding function through the special structure of the pressure plates. The outer edge of each pressure plate is turned outward to form a guiding structure. The two pressure plates are set back to back, so that the turned-out parts of the two pressure plates cooperate to form a stable guide groove. This guide groove can effectively constrain the movement trajectory of the yarn and ensure that the yarn passes smoothly between the limiting hole and the opening.

[0011] Furthermore, the opening of the baffle has an inner baffle and an outer baffle that protrude inwards, forming a "Z"-shaped channel within the opening.

[0012] The opening is equipped with two sets of raised structures, an inner baffle and an outer baffle. The inner baffle and the outer baffle are arranged alternately to form a continuous "Z" shaped channel inside the opening, which prevents the yarn from accidentally getting into the baffle during the guiding process, causing the yarn to become entangled and break.

[0013] Furthermore, the upper edge of the inner retaining strip is higher than the lower edge of the outer retaining strip.

[0014] The upper edge of the inner baffle is higher than the lower edge of the outer baffle, forming an alternating high and low anti-detachment structure.

[0015] Furthermore, the front end of the opening is an outwardly expanding guide port.

[0016] The front end of the opening is provided with an outwardly expanding guide port, which facilitates the smooth introduction of yarn into the internal channel of the baffle.

[0017] Furthermore, there are screw holes on the side wall above the opening, and the anti-reverse plate is fixed in the screw holes by bolts.

[0018] The side wall of the opening is provided with screw holes, and the anti-reverse plate is fixed by bolts engaging with the screw holes to form a reliable anti-reverse structure.

[0019] Furthermore, the anti-retraction piece is arc-shaped, with its end extending into the yarn limiting hole.

[0020] The anti-retraction plate adopts an arc-shaped design, with its end extending into the yarn limiting hole to form an effective anti-retraction protection structure.

[0021] Furthermore, the bottom of the opening is recessed downwards to form a clearance groove, and the end of the anti-retraction piece is inserted into the clearance groove.

[0022] The bottom of the opening is provided with a downward recessed relief groove, and the end of the anti-retraction piece is precisely engaged in the relief groove to form a stable limiting structure.

[0023] Furthermore, there is a gap between the end of the anti-retraction plate and the bottom of the clearance groove.

[0024] The end of the anti-retraction piece maintains a reasonable gap with the bottom of the clearance groove, which facilitates the yarn to be inserted into the yarn limiting hole from the gap.

[0025] Furthermore, there is a transitional arc surface between the bottom of the clearance groove and the yarn limiting hole.

[0026] The bottom of the clearance groove smoothly connects with the yarn limiting hole through a transition arc surface, ensuring that the yarn can be inserted smoothly without breaking.

[0027] By means of the above-described solution, the present invention has at least the following advantages: 1. Improved threading efficiency: By expanding the guide port and using a "Z"-shaped channel structure, the time for a single threading operation is reduced from 15-20 seconds to less than 5 seconds. This can save more than 8 minutes for an average of 50 threading operations per day, increasing the effective working time by 15%.

[0028] 2. Enhanced anti-fall-off performance: The gap fit design between the arc-shaped anti-reverse plate and the clearance groove reduces the yarn shedding rate by more than 90% and reduces the number of machine stops per 10,000 meters of fabric to less than once.

[0029] 3. Structural reliability optimization: The guide groove and transition arc surface design formed by the pressing reduces the yarn breakage rate by 80%, while the interlocking structure of the avoidance groove and the anti-retraction plate can withstand equipment vibration above 200Hz, improving the stability of yarn guidance.

[0030] 4. Improved human-computer interaction: The height difference design between the inner and outer guard strips, combined with the guide port, increases the error tolerance rate by 300%, allowing for precise threading without professional training.

[0031] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0035] See Figure 1 and Figure 2 The yarn guide is stably supported by the connecting bracket 1, the connecting plate 2 extends laterally to form a working platform, and the baffles 3 at both ends constitute the core area for yarn processing. The opening 4 on the side of the baffle 3 serves as a yarn inlet channel, and the yarn limiting hole 7 at the center achieves precise positioning. The two pressure plates 6 on the mounting column 5 form a dynamic guiding mechanism. The rigid connection between the connecting bracket 1 and the connecting plate 2 ensures overall stability. The straight channel between the opening 4 and the yarn limiting hole 7 simplifies the threading path. The vertical layout of the mounting column 5 optimizes space utilization. The nested structure of the two pressure plates 6 provides adjustable yarn pressure control. The top of the mounting column 5 has a threaded section, and the nut screwed into the threaded section limits the maximum bounce distance of the pressure plates 6.

[0036] See Figure 1 and Figure 2 The pressure plates 6 of this yarn guide feature an innovative structural design. The outer edge of each pressure plate 6 is turned outward to form a guiding slope. The two pressure plates 6 are arranged in a symmetrical back-to-back configuration, so that the turned-up parts of the two plates cooperate to form a stable guide groove. Its working process is as follows: when the yarn passes through the guide groove formed by the two pressure plates 6, the outward-turned structure produces a gradual guiding effect, while the back-to-back arrangement creates a self-centering effect.

[0037] See Figure 3 The yarn guide's baffle 3 features an innovative composite channel structure with inner baffle 8 and outer baffle 9. The alternating arrangement of the two sets of baffles within the opening 4 forms a precise "Z"-shaped guiding path. During use, this prevents the yarn located on both sides of the baffle 3 from rebounding from the opening 4 to the area between the two baffles due to vibration, thus ensuring the stability of the yarn guide.

[0038] The yarn guide achieves precise guiding control through the stepped layout of the inner baffle 8 and the outer baffle 9. The upper edge of the inner baffle 8 and the lower edge of the outer baffle 9 form a height difference structure, which further prevents the possibility of the yarn rebounding into the baffle 3.

[0039] See Figure 1 The yarn guiding device achieves efficient yarn entry through the guide port 10 at the front end of the opening 4. The guide port 10 adopts a unique trumpet-shaped outward expansion design. The yarn first contacts the gradually widening slope of the guide port 10, forming a transition area with gradually narrowing diameter at the entrance of the opening 4, so that the yarn automatically centers and enters the working channel.

[0040] See Figure 5 The anti-retraction plate 11 is fixedly installed through a structure of multiple bolts and screw holes. The anti-retraction plate 11 is made of a tough metal sheet that can be slightly deformed, which makes it easy for the yarn to drive the deformation of the anti-retraction plate 11 to complete the yarn insertion. The thickness of the anti-retraction plate 11 is about 2mm, so it will not cut the yarn.

[0041] This yarn guiding device achieves intelligent anti-retreat function through the synergistic effect of the arc-shaped anti-retreat plate 11 and the yarn limiting hole 7. The arc-shaped end of the anti-retreat plate 11 extends precisely into the interior of the yarn limiting hole 7 to form a physical barrier. During operation, as the yarn moves within the yarn limiting hole 7, the arc-shaped extension end of the anti-retreat plate 11 forms a dynamic contact surface with the inner wall of the yarn limiting hole 7. When the yarn advances normally, the arc-shaped surface provides a flexible gap of 0.5mm, and when the yarn retreats abnormally, it immediately forms a mechanical blockage.

[0042] The yarn guiding device achieves a dual positioning function through the precise fit between the clearance groove 12 at the bottom of the opening 4 and the end of the anti-retraction piece 11. The concave structure of the clearance groove 12 and the extended end of the anti-retraction piece 11 form a mechanical interlocking mechanism. When the anti-retraction piece 11 is installed in place, its end naturally embeds into the groove space of the clearance groove 12, so that the anti-retraction piece 11 obtains axial positioning while maintaining radial movement allowance.

[0043] The yarn guiding device achieves dynamic buffering function through a precision gap between the end of the anti-retraction piece 11 and the bottom of the clearance groove 12. The extended end of the anti-retraction piece 11 forms a non-contact floating structure in the space of the clearance groove 12. When the yarn passes through, the anti-retraction piece 11 can swing slightly along the clearance groove 12. The gap design ensures that the anti-retraction piece 11 does not have a rigid collision with the clearance groove 12.

[0044] The yarn guiding device achieves a smooth transition of the yarn trajectory through the transition arc surface between the bottom of the clearance groove 12 and the yarn limiting hole 7. The transition arc surface forms a continuous guide surface as a structural extension of the clearance groove 12 and the yarn limiting hole 7. When the yarn enters the clearance groove 12 area from the yarn limiting hole 7, the transition arc surface eliminates the yarn jamming phenomenon caused by the traditional right angle transition, allowing the yarn to slide naturally into the working area of ​​the clearance groove 12 with the optimal wrap angle.

[0045] The working principle of this utility model is as follows: This type of loom uses a quick yarn guide. When installing the yarn, hold both ends of the yarn and pull it to the sides to straighten it. This will bring the yarn close to the guide opening 10, and then move it inward to let the yarn enter the opening 4. Finally, the anti-reverse plate 11 will undergo a slight deformation to make the yarn lock into the yarn limiting hole 7, thus completing the yarn installation. Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
