Description

Technical Field

[0001] This utility model relates to the field of flocked paper processing technology, and in particular to a gluing device for flocked paper processing. Background Technology

[0002] Flocked paper is a decorative material made by vertically attaching short fiber flocking to the surface of coated paper using an electrostatic flocking process. It is widely used in gift packaging, home decoration, and high-end book covers. In the processing of flocked paper, gluing is a crucial step, as the quality of the gluing directly determines the firmness and uniformity of the flocking adhesion.

[0003] Currently, most traditional flocking paper gluing devices use scraping or roller coating methods to transfer glue to the base paper surface. These methods typically involve large coating amounts, making it difficult to achieve extremely thin glue layers. Excessively thick glue layers not only cause glue to penetrate to the roots of the flock fibers and even form a film on the surface, affecting the uprightness and softness of the flock fibers, but also result in excess adhesive failing to form an effective bond, leading to material waste and increased gluing costs. Furthermore, traditional flocking paper gluing devices often result in inconsistent glue layer thickness, easily producing striped or mottled unevenness. Therefore, to address the shortcomings of traditional flocking paper gluing devices in terms of glue layer thickness and uniformity, a new gluing device for flocking paper processing has been invented. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a gluing device for flocked paper processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gluing device for flocked paper processing includes a base, on which a gluing mechanism fixed to a frame is slidably connected. The gluing mechanism includes a glue storage tank, a spray gun located below the glue storage tank, and a filter connected between the glue storage tank and the spray gun. The spray gun consists of a gun body, a nozzle, and an air pump. The gun body has a gas chamber and a liquid chamber that are isolated from each other. The gas chamber is connected to the air pump, and the liquid chamber is connected to the output end of the filter. A stirring paddle is installed inside the glue storage tank, and a transmission assembly is installed on the outside of the glue storage tank. The transmission assembly is drivenly connected to the stirring paddle and fixedly connected to the top of the frame.

[0007] Preferably, the base is provided with a slide rail, and the bottom of the frame is provided with a sliding shoe that matches the slide rail. The sliding shoe is embedded in the slide rail and slidably connected to the slide rail.

[0008] Preferably, limit blocks are installed at both ends of the slide rail.

[0009] Preferably, the stirring paddle includes a stirring shaft and anchor blades fixedly connected to the bottom of the stirring shaft, the outline of which is adapted to the inner wall of the glue storage tank.

[0010] Preferably, the transmission assembly includes a motor and a reducer symmetrically fixed on both sides of the frame. The motor is connected to the reducer via a belt and a pulley. The output end of the reducer extends into the glue storage tank and drives the stirring paddle to rotate under the drive of the motor.

[0011] Preferably, the nozzle has a fan-shaped groove, and the fan-shaped groove has an array of spray holes.

[0012] Preferably, the pulley includes a driving pulley and a driven pulley, the driving pulley is sleeved on the output shaft of the motor, the driven pulley is connected to the input end of the reducer, and the belt is wound around the outer periphery of the driving pulley and the driven pulley.

[0013] Preferably, the top of the glue storage tank is provided with an openable glue storage cover, one side of which is hinged to the glue storage tank, and the other side of which is connected to the glue storage tank by a buckle.

[0014] The beneficial effects of this utility model are:

[0015] 1. By incorporating a reciprocating gluing mechanism on the base, stable translation of the gluing mechanism is ensured, achieving uniform spraying of the flocked paper. Simultaneously, the transmission components within the gluing mechanism drive the rotation of the stirring paddle within the glue storage tank, and in conjunction with a filter, the glue is filtered. This effectively prevents particulate matter sedimentation or stratification in the glue solution, removes impurities and undissolved particles, and ensures the uniformity and stability of the thick glue within the spray gun. Furthermore, by setting up mutually isolated gas and liquid chambers within the spray gun, the nozzle can produce more uniform and finer atomized particles, stably forming an extremely thin glue layer, thereby improving the gluing quality and flocking effect of the flocked paper.

[0016] 2. By creating fan-shaped grooves with an array of nozzles on the nozzle, the adhesive in the spray gun is atomized in a fan shape, which not only expands the coverage of a single spray but also effectively ensures the consistency and uniformity of the adhesive coating thickness. Anchor-type blades adapted to the inner wall of the tank are installed on the stirring paddle, and a transmission assembly consisting of a motor and reducer is used on the outside to uniformly stir the thick adhesive in the storage tank from all directions, preventing sedimentation and stratification due to settling, further improving the uniformity of the adhesive layer application.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figures 1 to 7 As shown, a gluing device for processing flocked paper includes a base 1, a frame 2 slidably connected to the base 1, and a gluing mechanism 3 fixedly connected to the frame 2. The gluing mechanism 3 includes a glue storage tank 4 fixedly connected to the frame 2, a spray gun 5 located below the glue storage tank 4, and a filter 6 connected between the glue storage tank 4 and the spray gun 5.

[0028] The glue storage tank 4 is equipped with a stirring paddle 7, which can enhance the fluidity of the thick glue in the glue storage tank 4, avoid the problem of particles settling and the upper layer of glue becoming thin when the glue is left to stand, and ensure that the thick glue can pass smoothly through the filter 6 and enter the spray gun 5, thereby avoiding the filter 6 from being blocked or the spray gun from being insufficiently supplied with glue due to the glue concentration being too high.

[0029] Furthermore, thick adhesive is prone to air mixing and forming bubbles during storage or application. If sprayed directly, the bubbles will burst and create a gap in the adhesive layer on the surface of the flocked paper. The rotation of the stirring paddle 7 can break up large bubbles and promote small bubbles to rise to the liquid surface and burst, reducing defects in the adhesive layer after spraying.

[0030] Furthermore, the stirring paddle 7 includes a stirring shaft 71 and an anchor blade 72 fixedly connected to the bottom of the stirring shaft 71. The outline of the anchor blade 72 is adapted to the inner wall of the glue storage tank 4. When the anchor blade 72 rotates, it can push the glue in the glue storage tank 4 to move circumferentially, thereby ensuring the uniformity of glue mixing.

[0031] refer to Figure 1 , Figure 2 As shown, a transmission assembly 8 is provided on the outside of the glue storage tank 4. The transmission assembly 8 is connected to the stirring paddle 7 and fixedly connected to the top of the frame 2. Specifically, the transmission assembly 8 includes a motor 81 and a reducer 82 symmetrically fixed on both sides of the frame 2. The motor 81 is connected to the reducer 82 through a belt 83 and a pulley 84. The motor 81 is a variable frequency motor, which can adjust the speed for glues of different viscosities.

[0032] Furthermore, the pulley 84 includes a driving pulley 841 and a driven pulley 842. The driving pulley 841 is sleeved on the output shaft of the motor 81, the driven pulley 842 is connected to the input end of the reducer 82, and the belt 83 is wound around the outer periphery of the driving pulley 841 and the driven pulley 842.

[0033] The output end of the reducer 82 extends into the glue storage tank 4 and drives the stirring paddle 7 to rotate under the drive of the motor 81. Since the motor 81 outputs a high speed, if the stirring paddle 7 is driven directly, the thick glue will splash due to the excessive speed. Therefore, the reducer 82 can reduce the high speed of the motor 81 to the low speed required for stirring, while increasing the torque to ensure that the stirring paddle 7 can stir the thick glue.

[0034] In addition, the top of the glue storage tank 4 is covered with an openable glue storage cover 41. One side of the glue storage cover 41 is hinged to the glue storage tank 4, and the other side of the glue storage cover 41 is connected to the glue storage tank 4 via a buckle 411. The glue storage cover 41 can lock in the moisture in the glue and maintain its stable fluidity, thereby preventing the thick glue from evaporating moisture and clumping due to long-term exposure to air. Furthermore, the glue storage cover 41 can isolate external dust, lint, debris and other impurities, thereby preventing the glue from being contaminated.

[0035] refer to Figure 6 , Figure 7 As shown, the spray gun 5 consists of a gun body 51, a nozzle 52, and an air pump 53 located on the gun body. The gun body 51 has a gas chamber 511 and a liquid chamber 512 that are isolated from each other. The gas chamber 511 is connected to the air pump 53. The air pump 53 is provided with an air pipe, which is connected to the gas chamber 511 to provide gas. The liquid chamber 512 is connected to the output end of the filter 6.

[0036] The gas chamber 511 and liquid chamber 512 are isolated from each other, which ensures that the gas and liquid do not mix in advance inside the spray gun 5, avoiding unstable atomization caused by the premature mixing of compressed air and glue. When the gas and liquid mix at the nozzle 52, the high-speed airflow of the gas will impact the glue, causing the glue to be torn into more uniform and finer particles to achieve atomization, so that the glue can be sprayed more evenly on the flocked paper, thereby improving the flocking effect.

[0037] Furthermore, the nozzle 52 is provided with a fan-shaped groove 521, and the fan-shaped groove 521 is provided with an array of spray holes 5211. The outline of the fan-shaped groove 521 presents a diffusion angle of 120°, which enables the glue mist sprayed from the spray holes 5211 to naturally form a fan-shaped coverage area, thereby expanding the width of a single spray of the nozzle 52 and improving the uniformity of the glue sprayed by the nozzle 52.

[0038] refer to Figure 1 , Figure 2 , Figure 4 As shown, a slide rail 11 is provided on the base 1, and a sliding shoe 21 matching the slide rail 11 is provided at the bottom of the frame 2. The sliding shoe 21 is embedded in the slide rail 11 and slidably connected to the slide rail 11. The sliding cooperation between the slide rail 11 and the sliding shoe 21 enables the frame 2 to move along the position of the slide rail 11 on the base 1, thereby driving the gluing mechanism 3 fixed on the frame 2 to move synchronously, so that the gluing range of the spray gun 5 gradually covers the flocked paper from one end to the other end.

[0039] Furthermore, limit blocks 111 are installed at both ends of the slide rail 11. The height of the limit blocks 111 is higher than the groove depth of the slide rail 11. When the slide shoe 21 slides to both ends of the slide rail 11, the limit blocks 111 will block the slide shoe 21 from continuing to slide, thereby preventing the gluing mechanism 3 on the frame 2 from detaching from the base 1. And since the frame 2 can only slide back and forth between the two limit blocks 111, it can ensure that the spray gun 5 of the gluing mechanism 3 is always spraying glue at the position of the flocked paper.

[0040] Working principle:

[0041] When the glue application device starts working, the anchor blades 72 on the stirring paddle 7, driven by the transmission component 8, stir the thick glue in the glue storage tank 4 in all directions. At the same time, the stirred glue flows through the filter 6 and removes impurities and undissolved particles through the internal filter element. Subsequently, the filtered clean glue enters the liquid chamber 512 inside the spray gun 5, while the gas in the air pump 53 enters the gas chamber 511, which is isolated from the liquid chamber 512. The gas and liquid finally reach the nozzle 52. Under the action of air pressure, the glue is sprayed out from the spray hole 5211 of the fan-shaped groove 521 in the form of a fan-shaped atomized surface. With the cooperation of the slide rail 111 and the slide shoe 21, the glue in the fan-shaped atomized surface gradually covers the flocked paper from one end to the other end, thereby achieving uniform spraying of the flocked paper.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
