Description

Technical Field

[0001] The utility model relates to the technical field of paper production, in particular to a glue spraying mechanism for paper production. Background Art

[0002] The main raw materials for paper include wood, bamboo, etc. These raw materials first need to be broken down into fine fibers, and the separated fibers are mixed with water to form a suspension called pulp. During this process, some chemicals are added to improve the quality of the paper, such as increasing its whiteness or strength. The prepared pulp is then fed into the mesh of the papermaking machine, where the water in the pulp is filtered out, leaving the fibers on the mesh to form wet paper sheets. The wet paper sheets then pass through a series of pressing rollers to further squeeze out excess water in the paper sheets, so that they reach a certain dryness and thickness.

[0003] After the wet paper sheets are formed, glue should be sprayed on them to bond multiple layers of paper together to obtain paper with higher strength and better quality. During the glue spraying process, in order to ensure the uniformity of the glue spraying, multiple atomizing nozzles will be installed on the glue spray hose to atomize the glue into glue mist that adheres to the paper.

[0004] However, if the atomizing nozzle is completely or partially blocked during use, the personnel on the production line cannot quickly discover it, resulting in the inability to deal with the blocked atomizing nozzle in time, affecting the uniformity of glue adhesion to the paper. Utility Model Content

[0005] The main purpose of the utility model is to provide a glue spraying mechanism for paper production, in which the glue mist diffusion area of ​​the atomizing nozzle is located in the illumination area of ​​the fill light device. Therefore, under the scattering and reflection of light, the diffusion of the glue mist is very obvious. When a certain atomizing nozzle is completely or partially blocked, personnel can clearly see that there is a problem with the glue mist diffusion of this atomizing nozzle, so that personnel can promptly inspect and repair it to ensure the uniformity of glue spraying on paper.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A glue spraying mechanism for paper production includes a box with an open top and a glue delivery pump. A glue spraying hose is fixed to the top of the box, and a plurality of atomizing nozzles are connected to the glue spraying hose. The glue discharge end of the glue delivery pump is connected to the glue spraying hose. A fill light device is fixed to one end of the glue spraying hose. The glue mist diffusion area of ​​the atomizing nozzle is located within the illumination area of ​​the fill light device.

[0008] Furthermore, a reflector that matches the position of the fill light device is fixed to the other end of the glue spraying tube, and the reflector and the fill light device are both fixed on the box.

[0009] Furthermore, the fill light device is a searchlight.

[0010] Furthermore, it also includes two groups of covers with openings facing downwards, and the two groups of covers are respectively located above the ends of both sides of the glue spraying tube.

[0011] Furthermore, brackets are fixed on both sides of the box, and the atomizing nozzle is fixed on the brackets.

[0012] Furthermore, two opposite sides of the cover body have inclined surfaces, the outward expansion angle of the inclined surfaces is 5 degrees to 15 degrees, and the inclined surfaces are staggered with a plurality of the atomizing nozzles.

[0013] Furthermore, both sides of the box body have slopes to form a glue concentration area, and a discharge pipe is fixed on the box body. The discharge pipe is connected to the glue concentration area and a valve is provided on the discharge pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The glue mist diffusion area of ​​the atomizing nozzle of the present invention is located in the illumination area of ​​the fill light device. Therefore, under the scattering and reflection of light, the diffusion of the glue mist is very obvious. When a certain atomizing nozzle is completely or partially blocked, the staff can clearly see that there is a problem with the glue mist diffusion of this atomizing nozzle, so that the staff can promptly carry out maintenance and ensure the uniformity of glue spraying on the paper.

[0016] 2. The cover of the present invention is located on the outer side above the atomizing nozzle at the end of the glue spraying hose, so the cover can collect the glue mist that spreads outward.

[0017] 3. The inclined surface of the utility model is staggered with the atomizing nozzle, and the glue in the cover body will fall along the inclined surface to minimize the possibility of the glue mist condensing directly dripping onto the atomizing nozzle.

[0018] 4. The glue that falls into the box will gather in the glue concentration area under the action of the slope. When the valve is opened, the glue in the box can be discharged through the discharge pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-3 As shown, a paper production glue spraying mechanism includes a box body 1 with an open top and a glue delivery pump 6. A glue spraying tube 4 is fixed to the top of the box body 1, and a plurality of atomizing nozzles 5 are connected to the glue spraying tube 4. The glue discharge end of the glue delivery pump 6 is connected to the glue spraying tube 4. A fill light device 2 is fixed to one end of the glue spraying tube 4. The glue mist diffusion area of ​​the atomizing nozzle 5 is located within the illumination area of ​​the fill light device 2.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, the fill light device 2 is a searchlight, and the glue delivery pump 6 is connected to the glue storage container. When the initially formed paper is transported at the top of the glue spraying tube 4, the glue delivery pump 6 works to absorb the glue from the storage container and spray it more evenly onto the transported paper through the atomizing nozzle 5. During this process, the fill light device 2 is turned on, and the glue mist diffusion area of ​​the atomizing nozzle 5 is located in the illumination area of ​​the fill light device 2. Therefore, under the scattering and reflection of light, the diffusion of the glue mist appears very obvious. When a certain atomizing nozzle 5 is completely or partially blocked, personnel can clearly see that there is a problem with the glue mist diffusion of this atomizing nozzle 5, so that personnel can promptly inspect and repair it to ensure the uniformity of glue spraying on the paper.

[0026] Among them, Figure 1 and Figure 2 As shown, a reflector 3 matching the position of the fill light device 2 is fixed to the other end of the glue spraying tube 4. The reflector 3 and the fill light device 2 are both fixed on the box 1. The reflector 3 can further improve the light utilization rate of the fill light device 2.

[0027] Among them, Figure 1 As shown, it also includes two sets of covers 7 with downward openings. The two sets of covers 7 are respectively located above the atomizing nozzles 5 at the two ends of the glue spraying tube 4. When the atomizing nozzles 5 at the ends spray glue mist, part of the glue mist will diffuse to the outside of the paper. The two sets of covers 7 are respectively located on the outer side above the atomizing nozzles 5 at the two ends of the glue spraying tube 4 (that is, the side away from the glue spraying tube 4), so the covers 7 can collect the glue mist that diffuses outward.

[0028] Among them, brackets 8 are fixed on both sides of the box body 1, and the atomizing nozzle 5 is fixed on the brackets 8. There are inclined surfaces 701 on both sides of the cover body 7 in the same length direction as the glue spraying tube 4, and the inclined surfaces 701 are staggered with the atomizing nozzle 5. The outward expansion angle of the inclined surface 701 is 5 degrees to 15 degrees. Therefore, the glue in the cover body 7 will fall along the inclined surface 701 to minimize the possibility of the glue condensed from the glue mist dripping directly onto the atomizing nozzle 5.

[0029] Among them, there are slopes 101 on both sides of the box body 1 to form a glue concentration area 105. The glue falling into the box body 1 will be collected in the glue concentration area 105 under the action of the slope 101. In addition, a discharge pipe 103 is fixed on the box body 1. The discharge pipe 103 is connected to the glue concentration area 105. A valve 104 is provided on the discharge pipe 103. When the valve 104 is opened, the glue in the box body 1 can be discharged through the discharge pipe 103.

[0030] Working principle: first, connect the glue delivery pump 6 to the glue storage container. When the preliminarily formed paper is transported at the top of the glue spraying pipe 4, the glue delivery pump 6 works to absorb the glue from the storage container and spray it more evenly onto the transported paper through the atomizing nozzle 5. During this process, the fill light device 2 is turned on. Since the glue mist diffusion areas of several atomizing nozzles 5 are located in the illumination area of ​​the fill light device 2, when a certain atomizing nozzle 5 is completely or partially blocked, the personnel can clearly see that there is a problem with the glue mist diffusion of this atomizing nozzle, so that the personnel can promptly inspect and repair it to ensure the uniformity of glue spraying on the paper. In addition, the cover body 7 can collect the glue mist diffused to the outside of the paper. The collected glue will fall into the box body 1 along the inclined surface 701 and gather in the glue concentration area 105. When the valve 104 is opened, the glue in the box body 1 can be discharged through the discharge pipe 103.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.

Such changes and improvements are intended to fall within the scope of the present invention.
