Description

Technical Field

[0001] This utility model relates to the field of optical adhesive feeding technology, and in particular to an optical adhesive uniform feeding device. Background Technology

[0002] Optical adhesive is a special adhesive with high light transmittance and high bonding strength, mainly used for bonding transparent optical components, such as touch screens, displays, glass covers, and lens assemblies. Its core characteristics include: high light transmittance (typically exceeding 90%), ensuring clear imaging of optical components and reducing light scattering and glare; low haze (less than 1%), avoiding visual blur and improving display quality; and strong weather resistance (resistant to UV rays, high temperatures, and high humidity, and does not yellow or delaminate with long-term use).

[0003] A search revealed that patent CN220738224U discloses an optical adhesive uniform application device. This device uses a glue sprayer to apply the optical adhesive, combined with a brush assembly to coat it, resulting in a more even distribution of the adhesive on the fabric surface. Two rollers press the coated fabric together, further improving adhesion and coating quality. However, the brush assembly can only apply the adhesive along the fabric's direction of movement, not laterally, thus failing to guarantee a completely uniform coating. Furthermore, the device cannot handle fabrics of varying widths; if the fabric width is less than the sprayer's, the adhesive sprayed from both sides will be spread over the outer edges of the fabric. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform optical adhesive feeding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an optical adhesive uniform feeding device, comprising two vertical plates, a storage box for storing optical adhesive being fixedly connected to the top of the two vertical plates, the top of the storage box being open, a crossbar being fixedly connected to the middle of the two vertical plates, a plurality of adhesive dispensing components being slidably connected to the middle of the crossbar, two width limiting components being slidably connected to the two ends of the crossbar, a drive shaft and a driven shaft being rotatably connected to the bottom of the two vertical plates via bearings, an application roller being fixedly connected to the surface of both the drive shaft and the driven shaft, and the two application rollers being in contact with each other, the width limiting component including a baffle slidably sleeved on the surface of the crossbar, the bottom of the baffle having a reserved opening for the two application rollers to pass through, and the inner sidewalls of the two reserved openings being in contact with the surfaces of the two application rollers, and a pump body connecting the storage box and the plurality of adhesive dispensing components being fixedly connected to the surface of any one of the vertical plates.

[0006] Furthermore, each of the dispensing components includes a first sliding sleeve slidably connected to the surface of the crossbar, and a nozzle is fixed to the outer wall of the first sliding sleeve. The first sliding sleeve sidewall is connected to a first fastening bolt through and via a threaded connection.

[0007] Furthermore, a flexible hose is fixedly connected to the top of the nozzle, a liquid extraction pipe is fixedly connected between the pump body inlet and the storage tank, a drain pipe is fixedly connected to the pump body outlet, and a connecting pipe is fixedly connected to the other end of the drain pipe. The flexible hose of each dispensing assembly is fixedly connected to the connecting pipe.

[0008] Furthermore, a second sliding sleeve is fixed to the top of the baffle, the second sliding sleeve is slidably connected to the crossbar, and a second fastening bolt is rotatably connected to the side wall of the second sliding sleeve through it via a thread.

[0009] Furthermore, a motor is fixed to the surface of any of the vertical plates near the drive shaft, and the drive shaft is fixedly connected to the output end of the motor.

[0010] Furthermore, gears are fixed at the ends of both the drive shaft and the driven shaft away from the motor, and the two gears mesh with each other.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model is an optical adhesive uniform feeding device, which is equipped with two vertical plates, a storage box, a crossbar, an adhesive dispensing component, two width limiting components, two coating rollers and a pump body. The pump body draws out the optical adhesive from the storage box and pumps it into the adhesive dispensing component. The adhesive dispensing component then sprays the optical adhesive onto the surface of the upper coating roller. Under the pressure of the two coating rollers, the optical adhesive is evenly transferred to the lower coating roller. The lower coating roller then applies the optical adhesive to the fabric, thereby further improving the uniformity of the application.

[0013] 2. When in use, this utility model is an optical adhesive uniform feeding device, which is equipped with a crossbar, an adhesive dispensing component and two width limiting components. By adjusting the two width limiting components to move along the surfaces of the two coating rollers, the width of the optical adhesive covering the coating roller surfaces can be changed, so that the coating rollers can apply optical adhesive to fabrics of different widths. This method of adjustment entirely through mechanical structure is faster and more convenient. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, an optical adhesive uniform feeding device is disclosed, comprising two vertical plates 1, with a storage tank 2 for storing optical adhesive fixedly connected to the top of the two vertical plates 1, and the top of the storage tank 2 being open. A crossbar 3 is fixedly connected to the middle of the two vertical plates 1, and multiple adhesive dispensing components 4 are slidably connected to the middle of the surface of the crossbar 3. Two width limiting components 5 are slidably connected to the two ends of the crossbar 3. A drive shaft 6 and a driven shaft 7 are rotatably connected to the bottom of the two vertical plates 1 via bearings. An applicator roller 8 is fixedly connected to the surface of both the drive shaft 6 and the driven shaft 7, and the two applicator rollers 8 are in contact with each other. The width limiting component 5 includes a baffle 51 slidably sleeved on the surface of the crossbar 3. The bottom of the baffle 51 has a reserved opening 52 for the two applicator rollers 8 to pass through, and the inner sidewall of the two reserved openings 52 is in contact with the surface of the two applicator rollers 8. A pump body 11 connecting the storage tank 2 and the multiple adhesive dispensing components 4 is fixedly connected to the surface of any vertical plate 1.

[0022] In this embodiment, mounting holes are provided at the bottom of both vertical plates 1. The device can be fixed to the top of the fabric composite device through the mounting holes, and the device can be laid across the fabric. The bottom of the coating roller 8 below is just in contact with the upper surface of the fabric.

[0023] Each dispensing assembly 4 includes a first sliding sleeve 41 that is slidably connected to the surface of the crossbar 3, and a nozzle 42 is fixed to the outer wall of the first sliding sleeve 41. A first fastening bolt 44 is threaded through the side wall of the first sliding sleeve 41 and rotatedly connected to it.

[0024] When it is necessary to adjust the width of the coating, firstly move the first sliding sleeve 41 of each dispensing assembly 4 along the crossbar 3 to adjust the gap between each nozzle 42, and then press the surface of the crossbar 3 by tightening the first fastening bolt 44, thereby fixing the first sliding sleeve 41 and the nozzle 42.

[0025] A hose 43 is fixedly connected to the top of the nozzle 42. A liquid extraction pipe 111 is fixedly connected between the inlet of the pump body 11 and the storage tank 2. A drain pipe 112 is fixedly connected to the outlet of the pump body 11, and a connecting pipe 12 is fixedly connected to the other end of the drain pipe 112. The hose 43 of each dispensing assembly 4 is fixedly connected to the connecting pipe 12.

[0026] After the pump body 11 is started, the optical adhesive inside the storage tank 2 is extracted through the pump body 11, and then injected into multiple hoses 43 along the drain pipe 112 and the connecting pipe 12 respectively. Finally, it is sprayed out from multiple nozzles 42, and the sprayed optical adhesive falls on the surface of the upper coating roller 8.

[0027] A second sliding sleeve 53 is fixed to the top of the baffle 51. The second sliding sleeve 53 is slidably connected to the crossbar 3. The side wall of the second sliding sleeve 53 is penetrated and connected to the second fastening bolt 54 by a threaded rotation.

[0028] When it is necessary to adjust the width of the coating, after adjusting the position of the nozzle 42, move the second sliding sleeve 53 to change the distance between the two baffles 51 so that the distance is exactly the same as the width of the fabric. Then tighten the second fastening bolt 54 to press the crossbar 3, thereby fixing the second sliding sleeve 53 and the baffles 51.

[0029] A motor 10 is fixed on the surface of any vertical plate 1 near the drive shaft 6, and the drive shaft 6 is fixedly connected to the output end of the motor 10.

[0030] Both the drive shaft 6 and the driven shaft 7 have gears 9 fixed at the ends away from the motor 10, and the two gears 9 mesh with each other.

[0031] In this embodiment, the motor 10 is a geared motor. After the motor 10 drives the drive shaft 6 to rotate, the driven shaft 7 will rotate in the opposite direction to the drive shaft 6 under the transmission of the two gears 9, so that the two application rollers 8 rotate in opposite directions. Under the pressure of the two application rollers 8, the optical adhesive on the surface of the upper application roller 8 will be evenly transferred to the surface of the lower application roller 8, and the baffle 51 will prevent the optical adhesive from overflowing to both sides, thereby realizing the control of the application width.

[0032] Working principle: Optical adhesive is added inside the storage tank 2. Then, the positions of multiple adhesive dispensing components 4 are adjusted according to the width of the fabric. The positions of the baffles 51 of the two width limiting components 5 are also adjusted so that the two baffles 51 are located on both sides of the fabric. After the adjustment is completed, the motor 10 is started to drive the two coating rollers 8 to rotate. The pump body 11 extracts the optical adhesive from inside the storage tank 2 and sprays it onto the surface of the upper coating roller 8 through the adhesive dispensing components 4. Under the pressure of the two coating rollers 8, the optical adhesive on the surface of the upper coating roller 8 is evenly transferred to the surface of the lower coating roller 8. The lower coating roller 8 then transfers the optical adhesive to the fabric surface that is in contact with it, thereby achieving uniform feeding.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
