Description

Technical Field

[0001] This utility model relates to the field of impregnated paper production technology, and in particular to a special spray impregnation equipment for impregnated paper. Background Technology

[0002] Impregnated paper is a composite paper formed by immersing base paper in resin (such as urea-formaldehyde resin or phenolic resin) or functional coating solution, and then drying and curing it. It has a smooth and flat surface, is wear-resistant and corrosion-resistant, and is mainly used for surface decoration of furniture, flooring, cabinets and other products. By hot-pressing it with the substrate, it gives the material aesthetics and durability.

[0003] A search revealed that the document with publication number "CN222594472U" mentions that "this application relates to the technical field of impregnated paper processing equipment, and discloses an impregnated paper dyeing, coating and drying device, including: a frame; an adsorption roller rotatably disposed at the top of the frame; a drive motor, which is connected to the adsorption roller and is fixedly disposed on the frame; and an adsorption tank disposed on the bottom side of the frame." In use, it can achieve the following technical effects: the impregnated paper can be stably adsorbed onto the adsorption roller through the adsorption holes; the drive motor can stably drive the adsorption roller to rotate, thereby driving the impregnated paper to be stably conveyed; and the adsorption tank at the bottom can adsorb and straighten the impregnated paper at the bottom, facilitating the drying of the impregnated paper. It can prevent the impregnated paper from swaying during drying, thus playing a role in stably conveying the impregnated paper. It can also prevent the decorative surface of the impregnated paper from contacting the roller, reducing contamination of the decorative surface of the impregnated paper.

[0004] However, in existing technologies, the production process of impregnated paper usually involves multiple steps, such as feeding, coating, and drying. These steps often require the cooperation of multiple pieces of equipment, and problems such as uneven impregnation, uneven coating, and poor drying effect are prone to occur during operation. Especially in the coating and drying stages, due to the lack of effective tension control and coating treatment methods, wrinkles, bubbles, or unevenness in the coating are easily caused, affecting product quality. In addition, existing impregnated paper production equipment is cumbersome and inefficient when changing materials, which increases production costs and time costs.

[0005] Therefore, we provide a special spray coating and impregnation equipment for impregnated paper to solve the above problems. Utility Model Content

An air shaft is connected to the inner slot of the shaft sleeve. An impregnated paper roll is sleeved on the surface of the air shaft. A pressure pump is connected to the end of the air shaft. The impregnated paper roll is wrapped with impregnated paper.

[0011] As a further description of the above technical solution:

[0012] The rotary motor and the air shaft are connected by a slot. The rotary motor and the air shaft are connected by a shaft sleeve to form a rotating structure. The rotary motor and the air shaft are symmetrically arranged on the left and right sides of the spray box. The air shafts are connected by an impregnated paper body.

[0013] As a further description of the above technical solution:

[0014] The force-bearing roller is rotatably connected to the tension sensor, and the tension sensor is rotatably connected to the straightening hydraulic rod. The force-bearing roller and the straightening hydraulic rod form a lifting and adjusting structure through the tension sensor.

[0015] As a further description of the above technical solution:

[0016] The alignment scraper is located on the upper side of the impregnated paper body. The alignment scraper is shaped with the left side higher than the right side. The figure-eight scraper has an inclined figure-eight structure. The impregnated paper body passes through the middle of the figure-eight scraper. The end of the figure-eight scraper is in close contact with the impregnated paper body.

[0017] As a further description of the above technical solution:

[0018] The upper nozzle is located on the upper side of the impregnated paper body, and the lower nozzle is located on the lower side of the impregnated paper body. The spraying direction of both the upper nozzle and the lower nozzle is the surface of the impregnated paper body.

[0019] As a further description of the above technical solution:

[0020] A drying chamber is located on the right side of the figure-eight scraper. Drying pipes are installed at both the upper and lower ends of the inner side of the drying chamber. A drying controller is installed on the upper side of the drying chamber. A side roller is located on the right side of the drying chamber. The impregnated paper body passes through the inner side of the drying chamber and is connected to the impregnated paper roll located on the right side via the side roller.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model utilizes an impregnated paper conveying assembly. When needed, the impregnated paper rolls located on the left and right sides of the spray box are driven by a rotary motor to rotate the air shaft for feeding. At this time, the impregnated paper rolls are fitted onto the outside of the air shaft, and the pressure is applied by a pressure pump to compress and fix the impregnated paper rolls. This ensures the stability of the impregnated paper during conveying and facilitates subsequent replacement. When the air shaft is inserted into the feeding support frame through the shaft sleeve, the rotating shaft at the end of the rotary motor will engage with the air shaft. Thus, when the rotary motor rotates, it drives the air shaft to rotate. Both sets of rotary motors rotate at the same speed and in the same direction, thereby winding the impregnated paper from the impregnated paper roll on the left side to the impregnated paper roll on the right side. During this process, the paper rotates at the same speed, which allows the impregnated paper to be evenly stressed, avoiding wrinkles or tears caused by uneven speed, and ensuring coating quality.

[0023] 2. This utility model utilizes an impregnation assembly for spraying impregnated paper. When the impregnated paper enters the spray box, it covers the upper surface of the force-bearing roller. At this point, the impregnated paper exerts downward pressure on the roller. A tension sensor monitors pressure changes in real time and feeds the data back to the corrective hydraulic rod, which automatically adjusts the roller height to maintain constant tension in the impregnated paper, ensuring uniform and deviation-free coating. Subsequently, the impregnated paper passes under the corrective scraper. Because the impregnated paper is at a relatively high height when entering the corrective scraper, it is guided by the scraper, which gradually presses it down and applies pressure to the surface of the impregnated paper. After a smoothing process, the impregnated paper is coated evenly by spraying from the upper and lower nozzles. Further pressing by a herringbone scraper ensures a tight seal, preventing air bubbles and achieving a high-quality coating. The coated paper then enters the drying chamber, where the drying tubes heat it evenly and the drying controller precisely regulates the temperature to ensure rapid curing and prevent deformation. Finally, the dried paper is wrapped around the right-side impregnated paper roll, achieving a winding effect. The side rollers guide and support the paper, preventing it from shifting during the drying process. Attached Figure Description

[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-7 As shown, this utility model provides a technical solution: a special spray coating and impregnation device for impregnated paper, including a spray box 1, impregnated paper conveying assemblies 2 arranged on the left and right sides of the spray box 1, and an impregnated paper spray coating and impregnation assembly 3 arranged on the upper side of the spray box 1. The impregnated paper spray coating and impregnation assembly 3 includes a straightening hydraulic rod 301 installed on the upper side of the spray box 1, a tension sensor 302 installed at the top of the straightening hydraulic rod 301, and a force-receiving roller 303 installed at the top of the tension sensor 302. An impregnation tank 304 is provided inside the spray box 1. A scraper 305 is provided on the right side of the straightening hydraulic rod 301. A straightening scraper 306 is welded to the top of the scraper 305. A nozzle frame 307 is provided on the right side of the scraper 305. An upper nozzle 308 is installed on the top of the nozzle frame 307. A lower nozzle 309 is provided on the right side of the upper nozzle 308. A figure-eight scraper 310 is provided on the right side of the nozzle frame 307. A liquid pump 311 is installed on the outside of the impregnation tank 304.

[0034] Furthermore, the impregnated paper conveying assembly 2 includes feeding support frames 201 installed on both the left and right sides of the spray box 1. A shaft sleeve 202 is connected to the upper slot of the feeding support frame 201. A rotary motor 203 is installed on the outer side of the feeding support frame 201. An air shaft 204 is connected to the inner slot of the shaft sleeve 202. An impregnated paper roll 205 is sleeved on the surface of the air shaft 204. A pressure pump 206 is connected to the end of the air shaft 204. The impregnated paper roll 205... The surface of 5 is covered with impregnated paper body 207. When needed, the impregnated paper rolls 205 located on the left and right sides of the spray box 1 are driven by the rotary motor 203 to rotate the air expansion shaft 204 for feeding. At this time, the impregnated paper rolls 205 are fitted onto the outside of the air expansion shaft 204, and the pressure pump 206 pressurizes the impregnated paper rolls 205 to squeeze and fix them. This ensures that the impregnated paper body 207 remains stable during the conveying process and facilitates later replacement.

[0035] Furthermore, the rotary motor 203 and the air shaft 204 are connected by a slot. The rotary motor 203 and the air shaft 204 form a rotating structure through the shaft sleeve 202. The rotary motor 203 and the air shaft 204 are symmetrically arranged on the left and right sides of the spray box 1. The air shafts 204 are connected by impregnated paper bodies 207. When needed, when the air shaft 204 is inserted into the feeding support frame 201 through the shaft sleeve 202, the rotating shaft at the end of the rotary motor 203 will engage with the air shaft 204. Thus, when the rotary motor 203 rotates, it drives the air shaft 204 to rotate. Both sets of rotary motors 203 rotate at the same speed and in the same direction, thereby winding the impregnated paper body 207 from the impregnated paper roll 205 on the left side to the impregnated paper roll 205 on the right side. Furthermore, rotating at the same speed during this process allows the impregnated paper body 207 to be evenly stressed, avoiding wrinkles or tears caused by uneven speed and ensuring coating quality.

[0036] Furthermore, the force-bearing roller 303 is rotatably connected to the tension sensor 302, and the tension sensor 302 is rotatably connected to the straightening hydraulic rod 301. The force-bearing roller 303 and the straightening hydraulic rod 301 form a lifting and adjusting structure through the tension sensor 302. When the impregnated paper body 207 enters the spray box 1, the impregnated paper body 207 will cover the upper surface of the force-bearing roller 303. At this time, the impregnated paper body 207 will exert downward pressure on the force-bearing roller 303. The tension sensor 302 monitors the pressure change in real time and feeds the data back to the straightening hydraulic rod 301, so that it automatically adjusts the height of the roller to keep the tension of the impregnated paper body 207 constant, ensuring uniform coating without deviation.

[0037] Furthermore, the alignment squeegee 306 is located on the upper side of the impregnated paper body 207, and the alignment squeegee 306 is shaped with the left side higher than the right side. The figure-eight squeegee 310 has an inclined figure-eight structure. The impregnated paper body 207 passes through the middle of the figure-eight squeegee 310, and the end of the figure-eight squeegee 310 is in close contact with the impregnated paper body 207. When it is needed, the impregnated paper body 207 passes through the lower side of the alignment squeegee 306. Since the impregnated paper body 207 is at a higher height when it enters the lower side of the alignment squeegee 306, it will be guided by the alignment squeegee 306. At this time, the alignment squeegee 306 gradually presses it down and smooths the surface of the impregnated paper body 207. After being sprayed by the upper nozzle 308 and the lower nozzle 309, the coating on the surface of the impregnated paper body 207 is uniform. Then, after being further pressed by the figure-eight squeegee 310, the coating is ensured to be tightly adhered, avoiding the generation of air bubbles, and finally achieving a high-quality coating effect.

[0038] Furthermore, the upper nozzle 308 is located on the upper side of the impregnated paper body 207, and the lower nozzle 309 is located on the lower side of the impregnated paper body 207. The spraying direction of both the upper nozzle 308 and the lower nozzle 309 is the surface of the impregnated paper body 207. When needed, the upper nozzle 308 and the lower nozzle 309 are started simultaneously. The impregnating liquid is drawn from the impregnating liquid tank 304 by the liquid pump 311 and sprayed evenly onto the surface of the impregnated paper body 207. By spraying simultaneously from both the upper and lower sides, the spraying efficiency can be improved, while ensuring that the impregnating liquid is evenly covered, avoiding local over-thickness or under-thickness, and improving the coating quality.

[0039] Furthermore, a drying chamber 312 is provided on the right side of the figure-eight scraper 310. Drying pipes 313 are installed at both the upper and lower ends of the inner side of the drying chamber 312. A drying controller 314 is installed on the upper side of the drying chamber 312. A side roller 315 is provided on the right side of the drying chamber 312. The impregnated paper body 207 passes through the inner side of the drying chamber 312 and is connected to the impregnated paper roll 205 located on the right side through the side roller 315. When needed, the impregnated paper body 207, after being sprayed and scraped by the figure-eight scraper 310, enters the drying chamber 312. The drying pipes 313 heat evenly, and the drying controller 314 precisely controls the temperature to ensure that the coating cures quickly and does not deform. Finally, the dried impregnated paper body 207 is wrapped around the impregnated paper roll 205 located on the right side, thereby achieving the function of winding. The side roller 315 guides and supports the impregnated paper body 207 to prevent it from shifting during the drying process.

[0040] Working principle: When needed, first place the spray box 1 in the desired position. Then, put the impregnated paper roll 205, which contains both unimpregnated and unimpregnated impregnated paper body 207, onto the air expansion shaft 204. Next, insert the air expansion shaft 204 into the shaft sleeve 202 on the left side, and then insert the shaft sleeve 202 onto the feeding support frame 201. At the same time, the end of the air expansion shaft 204 is engaged with the shaft at the end of the rotary motor 203. Then, the other end of the impregnated paper body 207... The paper is then fitted onto another impregnated paper roll 205, and, following the same procedure, secured to the air shaft 204 on the right side of the spray box 1. The impregnated paper body 207 will first be fitted onto the upper side of the force roller 303, then pass under the straightening scraper 306 on the scraper frame 305, between the upper nozzle 308 and the lower nozzle 309 on the nozzle frame 307, then through the middle of the figure-eight scraper 310, through the inner side of the drying chamber 312, and finally reach the side roller 315, where it meets the impregnated paper on the right side. After the paper rolls 205 are connected, the tension sensor 302 first senses whether the tension is within the preset range. Then, according to the change in value, the correction hydraulic rod 301 drives the force roller 303 to adjust its height. The left and right force rollers 303 adjust their tension respectively. Then, after being leveled by the correction scraper 306, the coating is drawn from the impregnation tank 304 by the liquid pump 311 through the upper and lower sides of the upper and lower nozzles 308 and lower nozzles for synchronous spraying. Then, the coating that may not be evenly sprayed is smoothed and pressed by the figure-eight scraper 310 and sent into the drying chamber 312. The drying controller 314 controls the drying tube 313 to bake at high temperature, so that the coating can be cured quickly and ensure that the impregnated paper body 207 is flat and wrinkle-free. Finally, it is guided by the side roller 315 and perfectly wrapped around the right impregnated paper roll 205, achieving an efficient and precise hand-rolling effect. This completes the use process of a special spray impregnation equipment for impregnated paper.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
