Description

Technical Field

[0001] The present application relates to the technical field of acrylic plate production, and in particular to a method and process for dynamically and uniformly cooling a nano antibacterial acrylic plate. Background Art

[0002] Acrylic sheet, also known as specially treated organic glass, is a replacement product of organic glass. Light boxes made of acrylic have the characteristics of good light transmission, pure color, rich colors, beautiful and flat, taking into account both day and night effects, long service life, and no impact on use. In addition, acrylic sheet can be perfectly combined with aluminum-plastic plate profiles, advanced screen printing, etc. to meet the needs of merchants.

[0003] At present, in order to improve the antibacterial property of the surface of the acrylic board, an additional nano antibacterial layer is applied after the acrylic board is processed to improve the antibacterial property. Since the prior art usually coats the nano antibacterial layer on the processed acrylic board, it is easy to gradually wear out or fall off during use. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a method and process for dynamically and uniformly cooling a nano-antibacterial acrylic plate to solve the technical problems in the background technology.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: A dynamic uniform cooling process of a nano antibacterial acrylic plate, comprising the following steps:

[0006] S1. Set up raw material processing equipment, extrusion equipment and cooling device, and add the materials required for the acrylic board into the raw material heating and pushing equipment;

[0007] S2, the raw material heating and pushing equipment pushes the melted raw materials out to initially form an acrylic sheet;

[0008] S3, applying liquid nano antibacterial coating on the initially formed acrylic plate;

[0009] S4, the acrylic plate and the liquid nano antibacterial coating are extruded together by an extrusion device, and the cooling device cools the acrylic plate at the same time;

[0010] S5. The acrylic sheet has solidified and is ready for subsequent processing.

[0011] By adopting the above technical scheme, by setting up raw material heating and pushing equipment, extrusion equipment and cooling device, the automation and continuity of the production process are realized, and the production efficiency is significantly improved. At the same time, the dynamic uniform cooling process ensures the temperature uniformity of the acrylic sheet during the solidification process, avoiding problems such as internal stress, deformation or cracking caused by uneven temperature. The addition of liquid nano antibacterial coating gives the acrylic sheet excellent antibacterial ability, which can effectively inhibit the growth of microorganisms such as bacteria and viruses. In addition, the process reduces the waste of raw materials and improves the utilization rate of materials by precisely controlling the heating, pushing and extrusion processes of the raw materials. The rapid cooling effect of the cooling device also helps to reduce energy consumption and production costs. The acrylic sheet treated by this process solidifies evenly and has a smooth surface, which is convenient for subsequent processing operations such as cutting, punching, and bending. Moreover, the use of liquid nano antibacterial coating is more environmentally friendly than traditional antibacterial methods, and the optimized design and precise control of the cooling device also help to reduce energy consumption and achieve green production.

[0012] Furthermore, the raw material processing equipment includes a strip pipe and two rotating shafts rotatably connected to the inside of the strip pipe, each of the rotating shafts is fixedly connected to a pushing spiral bar, a feed port is opened at the upper end of the strip pipe, a driving device for driving the two rotating shafts to rotate is arranged on the outside of the strip pipe, and a molding device for extruding the raw material is arranged at one end of the strip pipe away from the driving device.

[0013] By adopting the above technical solution, after the raw material particles are added into the strip pipe through the feed port, the inside of the strip pipe is heated to melt the raw material particles inside, and then the driving device is started to drive the two rotating shafts to rotate, so that the pushing thread strip pushes the raw material into the molding device to become an acrylic sheet.

[0014] Furthermore, the driving device includes a driving frame fixedly connected to the strip pipe, a driving motor is fixedly arranged on the driving frame, an output end of the driving motor is fixedly connected to one of the rotating shafts, linkage teeth are evenly fixedly arranged on the rotating shaft, and the linkage teeth on the two rotating shafts are meshed with each other.

[0015] By adopting the above technical solution, after the driving motor drives a rotating shaft to rotate, the interlocking meshing teeth on the rotating shaft will rotate together, and at the same time, the interlocking meshing teeth on another rotating shaft will rotate, so that the two rotating shafts can rotate at the same time, and the melted raw material inside the strip pipe can be pushed into the molding device.

[0016] Furthermore, the forming device is fixedly connected to an extrusion frame on one side of the strip pipe, a strip groove is opened at one end of the extrusion frame away from the driving motor, the strip groove is aligned with a transport device, a rectangular container for placing liquid nano antibacterial coating is fixedly arranged on the upper end of the extrusion frame, a roller coating shaft is arranged on the side of the rectangular container close to the strip groove, vertical plates are fixedly arranged on both sides of the rectangular container, the vertical plates and the roller coating shaft are rotatably connected, a linkage coating shaft is also rotatably arranged on the vertical plates, a synchronous belt is sleeved on the roller coating shaft and the linkage coating shaft, a linkage motor is fixedly arranged on the vertical plates, the output end of the linkage motor is fixedly connected to the linkage coating shaft, sponges are fixedly arranged on the outer sides of the linkage coating shaft and the roller coating shaft, and the sponges of the two are abutted against each other, and a lifting device is arranged at the bottom of the rectangular container.

[0017] By adopting the above technical solution, when the basically formed acrylic plate comes out of the strip groove of the extrusion frame, the linkage motor is started, which will drive the linkage coating shaft to rotate. The bottom of the linkage coating shaft contacts the liquid nano antibacterial coating inside the rectangular container. After rotation, it will be rotated by the sponge on the linkage coating shaft into the sponge on the rolling shaft. At the same time, the synchronous belt will also drive the rolling shaft to rotate together. The rolling shaft will apply the liquid nano antibacterial coating to the upper end of the acrylic plate just formed. The purpose of using double-axis coating in this application is to ensure that the liquid nano antibacterial coating can be evenly applied to the acrylic. At the same time, since the acrylic plate has just been formed and has not yet cooled, the coating will be completed. After cooling and solidification, the integrity of the liquid nano antibacterial coating and the acrylic plate can be improved.

[0018] Furthermore, the lifting device includes sliding rods fixedly arranged at both ends of the rectangular container, sliding racks for sliding the sliding rods are fixedly arranged on both sides of the extrusion frame, a lifting motor is fixedly arranged on the rectangular container, a lifting gear is fixedly arranged on the output end of the lifting motor, and a lifting rack bar is fixedly arranged on the extrusion frame, and the lifting gear and the lifting rack bar are meshed.

[0019] By adopting the above technical solution, in order to adjust the height of the rectangular container and the two coating shafts, the lifting gear is driven by the lifting motor to engage with the lifting rack bar, so that the rectangular container allows the sliding rod to move up and down in the sliding frame.

[0021] By adopting the above technical solution, when the extrusion electric cylinder is pressed down, the output end of the extrusion electric cylinder will be pressed down, which will first drive the negative pressure device to be pressed down. Since the acrylic plate is not completely solidified at this time, the roller frame is pressed down onto the acrylic plate that has been painted. Through double extrusion, the paint and the acrylic plate are squeezed at the same time, thereby further improving the integrity of the two. At the same time, the hair dryer setting can evenly complete the cooling.

[0022] Furthermore, the negative pressure device includes a connecting tube connected to the upper end of the roller frame, a negative pressure spring is installed in the connecting tube, a sliding groove is opened on the output end of the extrusion electric cylinder, and a sliding block sliding with the sliding groove is fixedly arranged on the inner side of the connecting tube.

[0025] By adopting the above-mentioned technical solution, in order to facilitate the replacement and installation of the negative pressure spring, this application is realized through the setting of the mounting plate and the mounting strip. Specifically, during installation, the mounting strip at the bottom of the mounting plate is inserted into the mounting groove of the connecting tube, and then the locking rod is rotated to allow the sliding columns at both ends of the locking rod to rotate to the adsorption magnets in the upper fixed groove and the lower fixed groove respectively, thereby completing the installation.

[0026] Furthermore, the rotating device includes an L-shaped frame fixedly connected to both sides of the roller frame, and driven rotating shafts are fixedly arranged at both ends of the extrusion roller. The driven rotating shaft and the L-shaped frame are rotatably connected, and a rotating motor is fixedly arranged on one of the L-shaped frames, and the output end of the rotating motor is fixedly connected to the driven rotating shaft.

[0027] By adopting the above technical solution, during the process of extruding the acrylic plate, the rotating motor drives the driven shaft to rotate while extruding.

At the same time, the dynamic uniform cooling method ensures the temperature consistency of the acrylic sheet during the cooling process, avoids internal defects and appearance flaws, and achieves stricter quality control. The introduction of liquid nano antibacterial coatings enables acrylic sheets to have excellent antibacterial properties, broadens the application field and enhances market value. In addition, the process optimizes the cooling process, improves cooling efficiency, saves energy and reduces consumption, and reduces production costs. The organic combination of multiple steps simplifies the traditional process flow, improves equipment utilization, and helps to realize the automation and intelligence of the production line.

The addition of liquid nano antibacterial coating gives the acrylic sheet excellent antibacterial ability, which can effectively inhibit the growth of microorganisms such as bacteria and viruses. In addition, the process reduces the waste of raw materials and improves the utilization rate of materials by precisely controlling the heating, pushing and extrusion processes of the raw materials. The rapid cooling effect of the cooling device also helps to reduce energy consumption and production costs. The acrylic sheet treated by this process solidifies evenly and has a smooth surface, which is convenient for subsequent processing operations such as cutting, punching, and bending. Moreover, the use of liquid nano antibacterial coating is more environmentally friendly than traditional antibacterial methods, and the optimized design and precise control of the cooling device also help to reduce energy consumption and achieve green production.

A molding device for extruding the raw material is provided at one end of the strip pipe 1 away from the driving device. After the raw material particles are added to the inside of the strip pipe 1 through the feed inlet 10, the inside of the strip pipe 1 is heated to melt the raw material particles inside, and then the driving device is started to drive the two rotating shafts 15 to rotate, so that the pushing spiral strip 14 pushes the raw material into the molding device to become an acrylic plate.
