Description

Technical Field

[0001] This invention relates to the field of textile machinery and equipment technology, and in particular to an automatic glue-applying device for textile rollers. Background Technology

[0002] The guide roller is a crucial component of the traction device in textile machinery. It is characterized by an iron core with bearings at both ends, upon which rotatable rubber rollers with outer diameters larger than the iron core are mounted. During spinning, the guide roller is responsible for twisting, stretching, and conveying the yarn, and its performance significantly impacts spinning efficiency and yarn quality. Due to the continuous pressure and scraping of the yarn against the guide roller surface over a prolonged period, damage inevitably occurs, most commonly resulting in grooves, directly affecting the quality of the spun yarn. Repairing the surface of textile guide rollers involves first grinding to remove defects, followed by applying a special adhesive to improve surface roughness and wear resistance. Currently, this adhesive application is primarily performed by experienced technicians. A group of rollers is placed at equal intervals on a roller tool tray, and the surface is repeatedly coated with adhesive-soaked cotton wool or fabric. This adhesive application method is not only labor-intensive and demanding, but the inconsistent application pressure and amount of adhesive each time result in varying repair quality and low efficiency on the yarn guide roller surface. Applying too much or too little force, or too much or too little adhesive, will affect the adhesive application quality on the yarn guide roller surface, sometimes requiring rework and directly impacting the adhesive application cost. Summary of the Invention

[0003] In view of the shortcomings of the above-mentioned prior art, which relies on manual surface adhesive repair, such as high labor intensity, low work efficiency, and difficulty in controlling adhesive quality, the applicant provides a reasonably structured automatic adhesive application device that can realize mechanical automation operation and has the advantages of automatic adhesive application, controllable quality, good adhesive effect, and high work efficiency.

[0004] The technical solution adopted in this invention is as follows:

[0005] An automatic glue applicator includes a glue box mounted on a frame, a roller placed on the glue box, a certain volume of glue liquid injected into the glue box, and a magnet block located at one end of the glue box. The magnet block is controlled by a magnet drive mechanism to move linearly along the length of the glue box, causing the roller on the glue box to roll linearly from the beginning to the end of the glue box, during which glue is applied.

[0006] As a further improvement to the above technical solution:

[0007] The glue box consists of two square boxes arranged side by side, spaced apart, corresponding to the two ends of the support roller.

[0008] The glue box contains a sponge and a layer of fabric covering the sponge. The glue box has an inlet for injecting glue liquid, and it also has an overflow outlet.

[0009] The magnet drive mechanism includes a horizontal feeding device and a horizontal feeding guide rail. The magnet block is fixed on the horizontal feeding device, and the horizontal feeding device moves linearly along the horizontal feeding guide rail.

[0010] A roller feeder is installed above the glue box, which transports the roller to the beginning of the glue box.

[0011] The roller feeding device includes a feed roller plate, an intermediate roller plate, and a discharge roller plate. The feed roller plate is equipped with a corresponding roller ejector frame, and the discharge roller plate is equipped with a corresponding vertical discharge device. The roller is conveyed to the beginning of the glue box via the feed roller plate and the intermediate roller plate. After applying glue, it is conveyed out of the glue box via the vertical discharge device and the discharge roller plate.

[0012] The top profile of the feed roller track consists of two inclined sections of rollers, with a blocking notch formed by the height difference between the two sections. A U-shaped groove is also provided on the rear section of the roller track. The roller ejector is raised and lowered by the roller ejector device. The top profile of the roller ejector is a sawtooth structure formed by two slopes, with a tooth between them. The tooth of the roller ejector is located between the blocking notch and the U-shaped groove of the feed roller track. The blocking notch of the feed roller track is located in the middle of the front slope of the roller ejector.

[0013] The intermediate roller plate is located on one side of the feed roller plate, forming an S-shaped or inclined roller track with the feed roller plate. The bottom of the intermediate roller plate is a horizontal straight line, forming a horizontal roller track with the glue box.

[0014] A vertical discharge device is provided at the tail end of the glue box. The vertical discharge device includes a vertical support, a vertical feeding frame, a vertical feeding guide rail, and a vertical feeding device. The vertical support is fixed at the tail end of the glue box and has a vertical plate corresponding to the glue box. A flat fabric layer is attached to the vertical plate. The vertical feeding frame is driven by the vertical feeding device and moves up and down vertically along the vertical feeding guide rail. When the vertical feeding frame rises, it drives the roller to roll on the flat fabric layer of the vertical plate.

[0015] The roller feeding device includes a feed roller plate and an intermediate roller plate. The feed roller plate is equipped with a corresponding roller ejector. The roller is conveyed to the beginning of the glue box via the feed roller plate and the intermediate roller plate. Alternatively, the roller feeding device includes a feed roller plate and a corresponding roller ejector. The roller is conveyed to the beginning of the glue box via the feed roller plate.

[0016] The beneficial effects of this invention are as follows:

[0017] The automatic glue-applying device of this invention features a glue box mounted on a frame, with a roller placed on top. A certain volume of glue liquid is injected into the glue box. A magnet is positioned at one end of the glue box, and the magnet, driven by a magnet-driven mechanism, rolls linearly along the length of the glue box from one end to the other, applying glue during this process. The magnet-driven mechanism is mechanically controlled, enabling automated operation and significantly improving production efficiency by replacing manual labor. This results in controllable glue application quality and superior glue-applying effect. The glue box consists of two parallel square boxes, corresponding to the two ends supporting the roller. A sponge and a fabric layer covering the sponge are placed inside the glue box. The glue box has an inlet and an overflow outlet to maintain a certain volume of glue liquid. This design offers extended service life, a convenient structure, and eliminates the need for manual supervision, making it more practical.

[0018] A roller feeding device is installed above the glue box, which transports the rollers to the beginning of the glue box. A roller ejector is installed at a corresponding position on the feed roller track, and its lifting and lowering are controlled by a roller ejection device. The coordinated lifting and lowering of the roller ejector and the feed roller track allows the rollers to be released one by one. An S-shaped or inclined roller track is formed between the intermediate roller track and the feed roller track, causing the rollers to roll down the curved or inclined track towards the beginning of the glue box. Simultaneously, the roller track provides cushioning, preventing the rollers from entering the beginning of the glue box at excessive speed. A horizontal roller track is formed between the bottom of the intermediate roller track and the glue box, ensuring that the rollers roll in a consistent horizontal direction during glue application. A vertical discharge device is installed at the tail end of the glue box to convey the rubber roller out of the glue box. At the same time, the rubber roller rolls on the flat fabric layer of the vertical plate, which makes the glue coating surface of the rubber roller more uniform and the effect better, and realizes the fully mechanized control operation.

[0026] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figures 1 to 6 As shown, the automatic glue applicator of this invention has a glue box 15 mounted on a frame. The glue box 15 consists of two parallel square boxes arranged side by side with a certain gap between them. A roller 3 can be placed on the two square boxes and roll horizontally in a straight line. Each square box contains a sponge and a layer of fabric covering the sponge. The square box has an inlet for injecting a certain amount of glue liquid into it. The square box also has an overflow outlet to discharge any glue liquid exceeding the set capacity, maintaining a constant glue liquid volume within the square box. A magnet block 13 is located at one end below the glue box 15. The magnet block 13 is controlled by a magnet drive mechanism to slide linearly along the length of the glue box 15. The magnet block 13 attracts the roller 3 above the glue box 15. During its horizontal linear movement, the magnet block 13 drives the roller 3 on the glue box 15 to roll linearly from the beginning to the end of the glue box 15, automatically applying glue during the rolling process. The magnet drive mechanism includes a horizontal feeding device 12 and a horizontal feeding guide rail 11. The magnet block 13 is fixed on the horizontal feeding device 12 by a magnet mounting plate 14. The horizontal feeding device 12 moves linearly along the horizontal feeding guide rail 11.

[0029] A roller feeding device is installed above the glue box 15, which conveys the roller 3 to the beginning of the glue box 15. The roller feeding device includes an infeed roller plate 1, an intermediate roller plate 5, and an outlet roller plate 6. Each of the three roller plates is composed of two parallel and opposite single plates, forming a guide rail that supports the roller 3. The infeed roller plate 1 is equipped with a roller ejector frame 2, and the outlet roller plate 6 is equipped with a vertical discharge device.

[0030] The tops of the two single plates of the feed roller plate 1 form the roller track of the roller 3. The outline of the top of the two single plates consists of two inclined roller tracks, one in front and one behind. Between the two inclined roller tracks is a blocking notch (i.e., waiting position) formed by the height difference. A U-shaped groove (i.e., cleaning position) is also provided on the rear roller track. A roller ejector 2 is set at the corresponding position of the feed roller plate 1. The roller ejector 2 is raised and lowered by the roller ejector device 16. The raising and lowering of the roller ejector 2 and the feed roller plate 1 cooperate to release the rollers 3 one by one. The roller ejector 2 is composed of two parallel and opposite single plates and is located between the two single plates of the feed roller plate 1. The top contours of the two single plates of the roller ejector 2 are a sawtooth structure composed of two front and rear ramps. The two ramps are approximately at the same height. The front ramp has a starting end (i.e., the stop position). A tooth (i.e., the limiting position) is formed between the two ramps. The tooth connects the front and rear ramps. The roller 3 rolls from the front ramp to the tooth position and is blocked and limited by the tooth.

[0031] The correspondence between the feed roller conveyor 1 and the roller ejector 2 is as follows: the teeth of the roller ejector 2 are located at the corresponding position between the blocking recess and the U-shaped groove of the feed roller conveyor 1, and the blocking recess of the feed roller conveyor 1 is located at the corresponding position in the middle of the front slope of the roller ejector 2. The technical effect achieved is to convey the rollers 3 one by one to the U-shaped groove of the feed roller conveyor 1. When the roller ejector 2 is initially located inside the feed roller conveyor 1 and its height is lower than that of the feed roller conveyor 1, the rollers 3 are conveyed to the waiting position of the front section of the feed roller conveyor 1 by the automatic feeding mechanism. When the roller ejector 2 is working, it is controlled to rise by the roller ejection device 16. When its height exceeds the rear section of the feed roller conveyor 1, the blocking position of the front slope of the roller ejector 2 separates the first roller 3 and the second roller 3 from each other. The first roller 3 rolls along the front slope of the roller ejector 2 to the limit position, while the second roller 3 is blocked. The roller ejector 2 is lowered to its initial position under the control of the roller ejector device 16, its height lower than that of the feed roller track 1. The first roller 3 moves along the rear section of the feed roller track 1 to the U-shaped groove, i.e., the cleaning position. A roller cleaning device 4 is installed at the corresponding position above the U-shaped groove of the feed roller track 1. The roller cleaning device 4 is driven up and down by the cleaning lifting device 17, which can approach the cleaning position of the roller 3 in the U-shaped groove to perform a pre-cleaning operation on the roller 3. When the roller ejector 2 is raised again under the control of the roller ejector device 16, the cleaned roller 3 is lifted out of the cleaning position and rolls downward, while the second roller 3 begins to repeat the above process.

[0032] The intermediate roller track 5 is located on one side of the feed roller track 1, forming an S-shaped or inclined roller track with it. This allows the roller 3 to roll along the curved or inclined roller track towards the beginning of the glue box 15, while simultaneously being cushioned by the roller track to prevent the roller 3 from entering the beginning of the glue box 15 at excessive speed. The bottom of the intermediate roller track 5 is a horizontal straight line, forming a horizontal roller track with the glue box 15. As the roller 3 rolls and applies glue on the glue box 15, it travels along the horizontal roller track from the beginning to the end.

[0033] A vertical discharge device is provided at the tail end of the glue box 15. The vertical discharge device forms a vertical roller track with the other side of the intermediate roller track plate 5. The vertical discharge device conveys the tail roller 3 out of the glue box 15. The vertical discharge device includes a vertical support 7, a vertical feeding frame 10, a vertical feeding guide rail 8, and a vertical feeding device 9. The vertical support 7 is fixed at the tail end of the glue box 15 and has two vertical plates corresponding to the glue box 15. A flat fabric layer is attached to the vertical plates. The vertical feeding frame 10 is composed of two parallel and opposite single plates. The tops of the two single plates are tilted towards the glue box 15. The vertical feeding frame 10 is located in the gap between the two square boxes of the glue box 15. Initially, the height of its top is lower than the height of the roller 3 in the glue box 15. The vertical feeding frame 10 is driven by the vertical feeding device 9 and moves up and down vertically along the vertical feeding guide rail 8. When the vertical feeding frame 10 rises, it can drive the rubber roller 3 to rise along the vertical support 7. At the same time, the rubber roller 3 rolls upward on the flat fabric layer of the vertical plate, making the coating surface of the rubber roller 3 more uniform.

[0034] A discharge roller plate 6 is set above the vertical discharge device. After the roller 3 reaches the top of the vertical roller, it rolls down along the discharge roller formed by the discharge roller plate 6 and enters the automatic tray loading mechanism.

[0035] The working process of the present invention will be described in detail below with reference to the accompanying drawings:

[0036] The rollers 3 requiring adhesive application are conveyed by the automatic feeding mechanism to the waiting position (front section) of the feed roller track 1. The roller ejection device 16 moves upward, causing the roller ejection frame 2 to rise to the corresponding position. During the upward movement of the roller ejection frame 2, the first roller 3 in the waiting position of the feed roller track 1 enters the previous ramp on the roller ejection frame 2 and continues to roll down the ramp. The limiting position on the roller ejection frame 2 blocks the rolling roller 3. The roller ejection device 16 moves downward, causing the roller ejection frame 2 to descend. The roller 3 in the limiting position of the roller ejection frame 2 is supported by the rear section of the feed roller track 1 and rolls down to the cleaning position on the feed roller track 1. The cleaning lifting device 17 drives the roller cleaning device 4 to descend, cleaning the roller 3. After cleaning is completed, the cleaning lifting device 17 drives the roller cleaning device 4 to rise to the corresponding position, and the roller ejection device 16 moves upward, driving the roller ejection frame 2 to rise to the corresponding position, so that the roller 3 in the waiting position of the feed roller plate 1 enters the previous ramp on the roller ejection frame 2 and rolls down to the limit position. At the same time, the cleaned roller 3 in the cleaning position of the feed roller plate 1 is ejected onto the roller track of the feed roller plate 1.

[0037] The cleaned roller 3 enters the glue box 15 along the S-shaped track formed by the feed roller plate 1 and the intermediate roller plate 5. The glue box 15 contains a sponge covering a fabric layer and has an inlet and an overflow outlet to ensure a certain liquid level. The horizontal feeding device 12 is activated, driving the magnet mounting plate 14, which contains the magnet block 13, to move horizontally along the horizontal feeding guide rail 11. Under the action of strong magnetic force, the roller 3 rolls horizontally in the glue box 15, thus evenly coating the glue in the glue box 15 onto the roller 3. The vertical feeding device 9 is activated, driving the vertical feeding frame 10 to rise along the vertical feeding guide rail 8 through the vertical track formed by the intermediate roller plate 5 and the vertical discharge device. The vertical feeding frame 10 drives the roller 3 to rise. During the rise of the roller 3, the glued roller rolls on the large plane of the vertical support 7, which contains a flat fabric layer, further improving the uniformity of the glue coating on the roller 3. After the roller 3 rises to the corresponding position, it enters the automatic tray loading mechanism via the discharge roller plate 6. The horizontal feeding device 12 returns to the starting position, and the vertical feeding device 9 descends to the starting position, waiting for the next operation. By repeating the above process, the function of automatically applying glue to multiple rollers 3 is realized.

[0038] Example 2

[0039] As another embodiment, Embodiment 2 differs from Embodiment 1 in that the structure of the roller feeding device is different. Specifically, a roller feeding device is installed above the glue box. The roller feeding device includes an infeed roller plate and an intermediate roller plate. The vertical discharge device at the tail end of the glue box can be replaced by other methods of removing the roller, and the discharge roller plate can also be replaced by other methods, as long as it satisfies the requirement of removing the roller at the tail end of the glue box. It is no longer limited to the vertical discharge device and discharge roller plate of Embodiment 1. The cooperation relationship between the infeed roller plate and the roller ejector remains unchanged.

[0040] Example 3

[0041] As another embodiment, Embodiment 3 differs from Embodiments 1 and 2 in that the structure of the roller feeding device is different. Specifically, a roller feeding device is installed above the glue box. The roller feeding device includes a feed roller track plate. The tops of the two single plates of the feed roller track plate form the roller track. The outline of the tops of the two single plates consists of two inclined roller tracks, one in front and one behind. The end of the rear roller track is located above the beginning of the glue box. After passing through the rear roller track, the roller directly enters the beginning of the glue box. The cooperation relationship between the feed roller track plate and the roller ejector remains unchanged.

[0042] Example 4

[0043] As another embodiment, Embodiment 4 differs from Embodiments 1, 2, and 3 in that it employs a different feeding and unloading method, replacing the structure used in the roller feeding device of Embodiments 1, 2, and 3. Specifically, the roller is conveyed to the beginning of the glue box by means of direct rolling or other methods. After the glue is applied to the glue box, the roller is removed by means of clamping or other methods.
