Description

Technical Field

[0001] This utility model relates to the field of tempered PS board processing technology, and in particular to a hardening liquid coating device for tempered PS boards. Background Technology

[0002] Tempered PS sheets are produced by applying a hardening agent to the surface of PS sheets (polystyrene plastic sheets), followed by constant-temperature sulfurizing and curing. This forms a strong and transparent protective film, significantly improving the surface hardness and wear resistance of the PS sheet, thereby extending its service life and ensuring that the PS sheet maintains its original gloss and transparency for a long time. In the process of applying the hardening agent to the surface of the PS sheet, a hardening agent application device is typically used to evenly apply the hardening agent to the surface of the PS sheet. The hardening agent application device includes a mounting frame, an application roller, a pressure distribution roller, and a liquid distribution head for distributing the hardening agent on the outer surface of the application roller. The lower surface of the liquid distribution head has several outlet holes. The hardening agent flows out from the outlet holes and falls onto the outer surface of the application roller. The pressure distribution roller rolls and presses the hardening agent on the application roller to distribute it evenly. Finally, the application roller applies the hardening agent to the surface of the PS sheet it is rolling with, achieving the purpose of applying the hardening agent.

[0003] Regarding the aforementioned related technologies, the inventors discovered that there are blind zones for the distribution of hardening liquid between adjacent liquid outlets. When the hardening liquid drips onto the outer circular surface of the coating roller, the pressure distribution roller squeezes the hardening liquid, making the hardening liquid evenly distributed in the axial direction of the coating roller. However, the hardening liquid flows slowly in the axial direction, with a small flow range and uneven distribution. This results in poor uniformity of the hardening liquid being applied to the PS board surface by the coating roller, causing the hardening liquid to form a wavy distribution, which reduces the quality of the tempered PS board. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a hardening liquid coating device for tempered PS sheets, which uniformly distributes the hardening liquid on the surface of the PS sheet, thereby improving the quality of the tempered PS sheet.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution for applying hardening liquid to tempered PS sheets, comprising: a mounting frame and an application roller rotatably connected to its inner cavity, one end of the application roller being connected to a servo motor, guide rollers being provided on the front and rear sides of the application roller, both ends of the guide rollers being rotatably connected to the mounting frame, a liquid distribution head assembly fixed to the mounting frame being provided above the application roller, the liquid distribution head assembly including a plurality of linearly arrayed liquid outlet holes, and a liquid supply tank assembly for conveying hardening liquid into the inner cavity of a sealed rectangular tube being connected to the mounting frame;

[0006] It also includes a radial adjustment support assembly, a reciprocating drive assembly, and an arc-shaped scraper assembly adapted to the outer circle of the application roller. The reciprocating drive assembly is connected to the arc-shaped scraper assembly and is adapted to drive the arc-shaped scraper assembly to reciprocate along the axial direction of the application roller. The radial adjustment support assembly is connected to the reciprocating drive assembly and is adapted to adjust the gap between the arc-shaped scraper assembly and the application roller.

[0007] By adopting the above technical solution, during use, the PS sheet is inserted between the coating roller and the guide roller, and the PS sheet is tumblingly connected to both the coating roller and the guide roller. The hardening liquid in the liquid supply tank assembly is delivered to the inner cavity of the liquid cloth head assembly. The hardening liquid in the liquid cloth head assembly flows out through the outlet hole and drips onto the outer surface of the coating roller. At this time, the servo motor drives the coating roller to rotate, and the hardening liquid on the outer surface of the coating roller is distributed in strips. The operation of the reciprocating drive assembly drives the arc scraper assembly to move back and forth along the axial direction of the coating roller, thereby scraping the hardening liquid on the outer surface of the coating roller axially, so that the hardening liquid is evenly distributed on the outer surface of the coating roller. The evenly distributed hardening liquid rotates with the coating roller and comes into contact with the surface of the PS sheet. The even distribution of hardening liquid on the surface of the PS sheet improves the quality of the tempered PS sheet. The gap between the arc scraper assembly and the coating roller can be adjusted by operating the radial adjustment support assembly to ensure that the hardening liquid has a suitable thickness.

[0008] In a preferred embodiment, the present invention can be further configured such that: the arc-shaped scraper assembly includes a strip plate and a plurality of arc-shaped scraper bodies adapted to the outer circle of the coating roller, the arc-shaped scraper bodies being arranged in a linear array and connected to the strip plate.

[0009] By adopting the above technical solution, the reciprocating drive component drives the strip plate to move back and forth, and the strip plate drives the arc-shaped scraper body to move, thereby scraping the hardening liquid on the outer surface of the coating roller, so that the hardening liquid is evenly distributed on the outer surface of the coating roller.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the reciprocating drive assembly includes a crossbar and a guide rail, the crossbar is connected to a strip plate via the guide rail, a mounting plate is connected to the side of the crossbar away from the guide rail, an electric push rod is connected to the mounting plate, and an L-shaped fixing plate is connected between one end of the electric push rod and the strip plate.

[0011] By adopting the above technical solution, the telescopic rod of the electric push rod one extends and retracts, thereby driving the arc-shaped scraper assembly to reciprocate through the L-shaped fixed plate. The distance the arc-shaped scraper assembly moves is greater than the gap between adjacent arc-shaped scraper bodies.

[0012] In a preferred embodiment, the present invention can be further configured as follows: the radial adjustment support assembly includes a fixed rod connected to the mounting frame, an electric push rod II is mounted on the fixed rod, the extended end of the electric push rod II is connected to the crossbar, guide rods are respectively provided on both sides of the electric push rod II, the guide rods are mounted on the fixed rod, and one end of the guide rods is connected to the crossbar.

[0013] By adopting the above technical solution, the telescopic rod of the electric push rod II extends and retracts, thereby adjusting the gap between the arc-shaped scraper body and the coating roller. Through the use of guide rods, the reciprocating drive assembly and the arc-shaped scraper assembly have strong stability.

[0014] In a preferred embodiment, the present invention can be further configured as follows: the liquid supply tank assembly includes a liquid supply tank body and a liquid outlet pipe connected to its bottom, the lower end of the liquid outlet pipe is sealed and connected with a plurality of liquid delivery pipes at intervals, the end of the liquid delivery pipe away from the liquid outlet pipe is respectively connected to a liquid fabric head assembly, and a switch valve is installed on the liquid outlet pipe.

[0015] By adopting the above technical solution, after operating the switch valve, the hardening liquid in the liquid supply tank flows from several liquid delivery pipes into the inner cavity of the liquid cloth head assembly. The hardening liquid in the liquid cloth head assembly then flows out through the liquid outlet and drips onto the outer surface of the coating roller.

[0016] In a preferred embodiment, the present invention can be further configured as follows: the liquid fabric head assembly includes a sealed rectangular tube, with connecting plates connected to both ends of the upper surface of the sealed rectangular tube, the outer ends of the connecting plates being connected to a mounting bracket, and a plurality of liquid outlet holes arranged in a linear array on the lower surface of the sealed rectangular tube.

[0017] By adopting the above technical solution, the sealed rectangular tube is connected to the mounting bracket through the connecting plate, and the hardening liquid in the liquid supply tank assembly is input into the inner cavity of the sealed rectangular tube. The hardening liquid drips onto the outer surface of the coating roller through the liquid outlet hole.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] The curing liquid inside the liquid cloth head assembly flows out through the outlet hole and drips onto the outer surface of the coating roller. At this time, the servo motor drives the coating roller to rotate, and the curing liquid on the outer surface of the coating roller is distributed in strips. The operation of the reciprocating drive assembly drives the arc scraper assembly to move back and forth along the axis of the coating roller, thereby scraping the curing liquid on the outer surface of the coating roller axially, so that the curing liquid is evenly distributed on the outer surface of the coating roller. The evenly distributed curing liquid rotates with the coating roller and comes into contact with the surface of the PS board. The even distribution of the curing liquid on the surface of the PS board improves the quality of the tempered PS board. Attached Figure Description
