Description

Technical Field

[0001] This utility model relates to the field of PC sheet roll surface treatment technology, specifically a PC sheet roll surface hardening treatment device. Background Technology

[0002] PC sheet, also known as polycarbonate sheet, polyester sheet, or Kapron sheet, is resistant to weak acids. It is made of polycarbonate as the main component using co-extrusion technology. PC sheet is resistant to neutral oils but not to strong acids, and it is not durable or alkali-resistant. To enhance the surface strength of PC sheet rolls during use, a coating is usually added to the surface of the PC sheet roll.

[0003] An existing patent (publication number: CN218902427U) discloses a PC sheet roll surface hardening treatment device, including a conveyor table, a coating chamber, and a curing chamber. The coating chamber is arranged on the conveyor table, and a curing chamber is arranged on one side of the coating chamber. The bottom of both the coating chamber and the curing chamber are provided with through grooves. Coating rollers are arranged on the inner wall of the coating chamber, and four coating rollers are installed. The front and rear ends of the four coating rollers are provided with rotating shafts. Coating brushes are installed on the surface of the four coating rollers. Spray nozzles are arranged above the coating rollers, and several spray nozzles are arranged. A lifting plate is installed on the top of the spray nozzles, and pneumatic telescopic rods are arranged on both sides of the upper surface of the lifting plate.

[0004] The aforementioned patent describes a coating roller and nozzle installed inside the coating chamber. During processing, the coating is delivered to the nozzle through a telescopic coating tube. A cylinder drives a pneumatic telescopic rod to move a lifting plate downwards, spraying the coating. A motor drives a rotating shaft to coat the coating roller and coating brush evenly on the surface of the board. However, in actual use, the centrifugal force generated by the rotation of the coating roller causes some coating to be thrown off the surface of the PC sheet roll. This not only wastes the coating but may also leave coating residue in the coating chamber, affecting the cleanliness of the subsequent processing environment and the smoothness of the coating surface. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a PC sheet roll surface hardening treatment device, which has the advantage of uniform coating application and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PC sheet roll surface hardening treatment device, comprising an outer shell, an internal coating assembly for coating, the coating assembly including a support plate, a plurality of nozzles with independent switches mounted on the bottom surface of the support plate, a storage tank for storing coating material mounted on the upper surface of the outer shell, a first pump mounted on the upper surface of the support plate, the input end of the first pump being connected to the storage tank, the output end of the first pump being connected to the plurality of nozzles, a scraper fixed on the bottom surface of the support plate, and an electric push rod mounted on the inner top wall of the outer shell, the other end of the electric push rod being connected to the support plate.

[0007] Furthermore, a storage box is slidably connected to the bottom surface of the outer shell. The inner bottom wall of the storage box is inclined and designed to guide the flow. A fixing plate is fixed to the top of the storage box. The fixing plate is located below the scraper, and the side of the fixing plate is flush with the side of the scraper.

[0008] With the above solution, when the scraper scrapes the coating on the surface of the PC sheet roll, the fixing plate supports the PC sheet roll directly below the scraper. The scraper removes excess coating, which falls into the storage box and is guided to one end of the storage box by its tilt.

[0009] Furthermore, a second pump is installed on the side of the storage tank. The input end of the second pump is connected to the storage box, and the output end of the second pump is connected to the storage tank.

[0010] Through the above scheme, the second pump can transport the excess paint collected in the collection box back to the storage tank, realizing the recycling of paint, effectively reducing paint waste and lowering production costs.

[0011] Furthermore, the inner wall of the outer shell is provided with a sliding groove, and a corresponding slider is fixed on the side of the storage box, the slider being slidably connected to the sliding groove.

[0012] With the above solution, after the entire coating operation is completed, the storage box can be pulled out and cleaned to avoid paint residue affecting the next use. The cooperation between the slider and the groove can ensure that the storage box remains stable during the pulling process and prevent paint from spilling.

[0013] Furthermore, a feed inlet is provided on one side of the outer casing, and a discharge outlet is provided on the other side. Guide rollers are rotatably connected inside both the feed inlet and the discharge outlet. Multiple ultraviolet curing lamps are provided inside the outer casing behind the coating assembly, and the ultraviolet curing lamps are installed on the inner top wall of the outer casing.

[0014] The above scheme uses guide rollers to guide the conveying of PC sheet rolls, ensuring that the PC sheet rolls can smoothly enter and leave the housing. Ultraviolet curing lamps can cure the coating on the surface of the coated PC sheet rolls, improving curing efficiency and curing effect.

[0015] Furthermore, the interior of the outer casing is provided with a correction assembly for correcting deviations. The correction assembly includes two track grooves disposed within the outer casing. Each track groove has two track blocks slidably connected to its inner wall. A movable plate is fixed to the bottom surface of each track block. A mounting block is fixed to the bottom surface of the middle position of the movable plate. A correction wheel is mounted on the bottom surface of the mounting block. A correction motor is mounted on the side of the mounting block. The correction motor is connected to the corresponding correction wheel. Scanning devices are mounted on the bottom surfaces of both ends of the movable plate. The scanning devices are connected to an external control device.

[0016] Through the above scheme, the scanning equipment monitors the edge position of the PC board roll in real time and transmits the data to the control device. When the PC board roll deviates during the transmission process, the external control device controls the correction motor to start, and the correction motor drives the correction wheel to rotate to correct the PC board roll.

[0017] Furthermore, an adjusting motor is installed at the end of the track groove, and an adjusting threaded rod is installed at the output end of the adjusting motor. The outer surface of the adjusting threaded rod is provided with a bidirectional threaded groove. The adjusting threaded rod is threadedly connected to the track block. A hydraulic rod is installed on the inner top wall of the outer shell, and a lifting plate is installed at the output end of the hydraulic rod. The two track grooves are fixed to the lifting plate.

[0018] The above scheme adjusts the adjustment screw rod by rotating it when the motor starts. Since the outer surface of the adjustment screw rod has a bidirectional threaded groove and is threadedly connected to two track blocks, the two track blocks will move relative to each other or towards each other along the track groove, thereby driving the moving plate and the correction wheel to move synchronously. This achieves the adaptation and adjustment of PC sheet rolls of different widths. The hydraulic rod can drive the track groove to move up and down as a whole through the fixed plate, thereby adjusting the contact pressure between the correction wheel and the surface of the PC sheet roll, ensuring the correction effect while avoiding damage to the surface of the PC sheet roll.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] This PC sheet roll surface hardening treatment device uses a scraper and a fixing plate to smooth the coating, avoiding uneven coating and surface unevenness, thus improving coating quality. The storage box collects excess coating, and the second pump returns it to the storage tank for recycling, reducing waste and lowering costs. The correction component corrects deviation in real time, adapts to rolls of different widths, and prevents coating damage. The pull-out design of the storage box makes it easy to clean and ensures the cleanliness of the equipment. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a PC sheet roll surface hardening treatment device includes a housing 1. Inside the housing 1, a coating component 2 for coating is provided. The coating component 2 includes a support plate 201. Multiple nozzles 202 with independent switches are installed on the bottom surface of the support plate 201. A storage tank 203 for storing coating is installed on the upper surface of the housing 1. A first pump 204 is installed on the upper surface of the support plate 201. The input end of the first pump 204 is connected to the storage tank 203, and the output end of the first pump 204 is connected to the multiple nozzles 202. A scraper 205 is fixed on the bottom surface of the support plate 201. An electric push rod 206 is installed on the inner top wall of the housing 1, and the other end of the electric push rod 206 is connected to the support plate 201.

[0032] Please see Figure 2 , Figure 3 and Figure 4 A storage box 3 is slidably connected to the bottom surface of the outer shell 1. The inner bottom wall of the storage box 3 is inclined and designed for flow guidance. A fixing plate 4 is fixed to the top of the storage box 3. The fixing plate 4 is located below the scraper 205, and the side of the fixing plate 4 is flush with the side of the scraper 205. When the scraper 205 scrapes the coating on the surface of the PC sheet roll, the fixing plate 4 supports the PC sheet roll directly below the scraper 205. The scraper 205 scrapes off the excess coating, and the coating falls into the storage box 3. It is then guided to one end of the storage box 3 by the inclined flow. A second pump 5 is installed on the side of the storage tank 203. The input end of the second pump 5 is connected to the storage box 3, and the output end of the second pump 5 is connected to the storage tank 203. The second pump 5 can re-transport the excess coating collected in the storage box 3 back to the storage tank 203, realizing the recycling of coating, effectively reducing coating waste, and lowering production costs.

[0033] Please see Figure 2 , Figure 3 and Figure 4 The inner wall of the outer shell 1 is provided with a sliding groove, and the side of the storage box 3 is fixed with a corresponding slider 6. The slider 6 is slidably connected to the sliding groove. After the entire coating operation is completed, the storage box 3 is pulled out and cleaned to avoid paint residue affecting the next use. The cooperation between the slider 6 and the sliding groove can ensure that the storage box 3 remains stable during the pulling process and prevent paint spillage. One side of the outer shell 1 is provided with a feed port and the other side is provided with a discharge port. The inside of both the feed port and the discharge port is rotatably connected with guide rollers 7. Multiple ultraviolet curing lamps 8 are set inside the outer shell 1 behind the coating component 2. The ultraviolet curing lamps 8 are installed on the inner top wall of the outer shell 1. The guide rollers 7 are used to guide the conveying of the PC board roll material to ensure that the PC board roll material can smoothly enter and leave the interior of the outer shell 1. The ultraviolet curing lamps 8 can cure the coating on the surface of the coated PC board roll material, improving the curing efficiency and curing effect.

[0034] Please see Figure 2 , Figure 3 and Figure 4 The outer casing 1 contains a web-correcting assembly 9. The web-correcting assembly 9 includes two track grooves 901 within the outer casing 1. Each track groove 901 has two track blocks 902 slidably connected to its inner wall. A movable plate 903 is fixed to the bottom surface of each track block 902. A mounting block 904 is fixed to the bottom surface of the middle position of the movable plate 903. A web-correcting wheel 905 is mounted on the bottom surface of the mounting block 904. A web-correcting motor 906 is mounted on the side of the mounting block 904 and connected to the corresponding web-correcting wheel 905. Scanning devices 907 are mounted on the bottom surfaces of both ends of the movable plate 903 and are connected to an external control device. The scanning devices 907 monitor the edge position of the PC sheet roll in real time and transmit the data to the control device. When the PC sheet roll deviates during transmission, the external control device activates the web-correcting motor 906, which drives the web-correcting wheel 905 to rotate and correct the PC sheet roll. Adjustment devices are installed at the ends of the track grooves 901. The adjustable motor 908 has an adjustable threaded rod 909 installed at its output end. The outer surface of the adjustable threaded rod 909 has a bidirectional threaded groove. The adjustable threaded rod 909 is threadedly connected to the track block 902. A hydraulic rod 910 is installed on the inner top wall of the outer shell 1. A lifting plate 911 is installed at the output end of the hydraulic rod 910. The two track grooves 901 are fixed to the lifting plate 911. When the adjustable motor 908 starts, it drives the adjustable threaded rod 909 to rotate. Since the outer surface of the adjustable threaded rod 909 has a bidirectional threaded groove and is threadedly connected to the two track blocks 902, the two track blocks 902 will move relative to or towards each other along the track grooves 901. This will drive the moving plate 903 and the correction wheel 905 to move synchronously, so as to realize the adaptation and adjustment of PC sheet rolls of different widths. The hydraulic rod 910 can drive the track groove 901 to move up and down as a whole through the fixed plate 4, thereby adjusting the contact pressure between the correction wheel 905 and the surface of the PC sheet roll, ensuring the correction effect while avoiding damage to the surface of the PC sheet roll.

[0035] It should be noted that after the entire coating operation is completed, the storage box 3, scraper 205 and the corresponding pipes need to be cleaned.

[0036] The working principle of the above embodiment is as follows: The PC sheet roll enters from the feed port on one side of the outer shell 1. The guide rollers 7 inside the feed port and the discharge port rotate synchronously, guiding the roll smoothly into the device in a horizontal direction. This avoids wrinkles or deviations caused by uneven force during the initial conveying of the roll, laying a stable foundation for subsequent coating. After the roll enters, the scanning device 907 of the correction component 9 monitors the edge position of the roll in real time and transmits the data to the external control device. If the roll deviates, the control device immediately starts the correction motor 906 on the side of the mounting block 904. The correction motor 906 drives the correction wheel 905 to rotate, pushing it through friction. The roll material returns to the preset conveying path; simultaneously, the adjusting motor 908 at the end of the track groove 901 can be activated according to the width of the roll material. The adjusting motor 908 drives the adjusting threaded rod 909 with a bidirectional threaded groove on its outer surface to rotate, so that the two track blocks 902 in the track groove 901 slide relative to or towards each other along the groove, thereby driving the moving plate 903 and the straightening wheel 905 to adjust the spacing synchronously to adapt to PC roll materials of different widths; the hydraulic rod 910 can also drive the track groove 901 to move up and down as a whole through the lifting plate 911 to adjust the contact pressure between the straightening wheel 905 and the surface of the roll material, ensuring the straightening effect while avoiding scratching the surface of the roll material.

[0037] Based on the thickness of the PC sheet roll and the preset coating thickness, the electric actuator 206 on the inner top wall of the outer casing 1 is activated. The electric actuator 206 pushes the support plate 201 to rise and fall vertically, adjusting the nozzle 202 and scraper 205 to a suitable height from the surface of the roll. The first pump 204 is then activated, pressurizing and conveying the hardened coating in the storage tank 203 to multiple independent nozzles 202 on the bottom surface of the support plate 201. By controlling the on / off state of each nozzle 202, precise coating of different areas of the roll is achieved, ensuring that the initial coating coverage is uniform. The coated roll continues to be conveyed to the area below the scraper 205. The scraper 205 and the fixing plate 4 below work together. The fixing plate 4 provides rigid support for the roll, preventing the roll from denting when the scraper 205 applies pressure. The scraper 205 moves horizontally along the surface of the roll, scraping off excess coating to ensure a uniform coating thickness, while avoiding the uneven coating problem caused by centrifugal force throwing of traditional coating rollers.

[0038] Excess paint scraped off by scraper 205 falls into the storage box 3 below under gravity. The bottom wall of the storage box 3 has an inclined guide design, which can guide the paint to a concentrated area at one end of the storage box 3. The second pump 5 on the side of the storage tank 203 is activated. The second pump 5 pumps the excess paint in the storage box 3 back to the storage tank 203 through the pipeline, realizing the closed-loop recycling of paint and reducing paint waste. At the same time, the storage box 3 is slidably connected to the inner wall groove of the outer shell 1 by the side slider 6, which can be easily pulled out later to facilitate cleaning of residual paint and prevent paint from drying and affecting the next use.

[0039] After the PC sheet roll is coated and smoothed, it continues to be conveyed to the ultraviolet curing lamp 8 inside the outer casing 1. The ultraviolet curing lamp 8 continuously irradiates the hardening coating on the surface of the roll, causing the active ingredients in the coating to cross-link and cure rapidly, forming a dense hardened layer, which improves the wear resistance and scratch resistance of the PC sheet roll surface.
