Description

Technical Field

[0001] This utility model relates to the field of canvas drying technology, and in particular to a drying device for canvas processing. Background Technology

[0002] In the field of canvas processing, drying is a key step to ensure the quality of finished canvas products and the effect of subsequent processing. At present, conventional canvas drying equipment on the market generally suffers from low energy utilization. The hot air flow of most devices is easily lost directly in the drying chamber and cannot form an effective circulation, which leads to the need for continuous high-intensity heating to maintain the temperature required for drying, resulting in a lot of energy waste, and at the same time, it is difficult to improve the drying efficiency. In terms of safety and environmental friendliness, existing equipment lacks effective heat insulation and sealing design. During the drying process, the high temperature inside the chamber can easily be conducted to the outside, which may not only pose a risk of burns to operators but also affect the normal operation of external control components (such as the control panel), leading to frequent equipment failures. In addition, some equipment does not have a reliable waste liquid collection and sealing structure, and the waste liquid dripping during canvas processing is prone to leakage, polluting the working environment and increasing subsequent cleaning costs. Regarding canvas positioning and transmission stability, the positioning components of traditional equipment have poor adaptability and can only limit the movement of canvas of specific specifications. When dealing with canvas of different thicknesses and widths, special positioning components need to be replaced, which is cumbersome and increases equipment investment. At the same time, there is a lack of real-time speed monitoring and dynamic adjustment mechanisms during canvas transmission, which can easily lead to canvas tearing due to uneven force or abnormal transmission speed, resulting in raw material loss and processing delays. Therefore, the above problems need to be solved. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves the drying of canvas through the cooperation of drying components and auxiliary positioning components. Not only does the inverted plate design of the partition plate create a vortex in the hot air during the drying stage, improving the temperature utilization rate of the collection chamber and reducing energy consumption, thus enhancing the drying effect without additional heating, but the rock wool insulation board also prevents high-temperature damage to operators inside the drying chamber and avoids malfunction of the control panel due to high temperatures. It also ensures a tight seal between the collection box and the drying box, preventing waste liquid leakage and pollution of the working environment. During canvas installation, a stepper motor drives a bidirectional lead screw to move the pressing rollers in opposite directions or relative to each other. This, combined with guide rollers, precisely limits the canvas of different specifications. A laser sensor monitors the canvas movement speed in real time, preventing tearing due to uneven force or abnormal speed, thus achieving stable canvas transport and drying. The height of the guide rollers can be adjusted by rotating the lead screw to accommodate different canvas thicknesses, eliminating the need for customized positioning components. All components are bolted to the corresponding chambers, eliminating the need for additional supports, reducing space occupation and the number of parts, and meeting the requirements of canvas processing for compact equipment structure and stable drying.

[0012] 2. The auxiliary positioning component in the drying chamber of this utility model, in conjunction with the hot airflow generated by the drying component, allows waste liquid dripping from the canvas surface to enter the collection chamber through the through-holes in the partition plate while drying the canvas. The waste liquid then flows into the collection box via the collection trough, preventing residual waste liquid from contaminating the drying environment or the canvas. The second filter and air inlet box work together to prevent impurities in the air from entering the drying chamber and contaminating the canvas, ensuring the quality of the canvas processing. The second fan, in conjunction with the heating pipe, continuously provides a stable hot airflow to the drying chamber, working with the first fan to regulate the air pressure inside the drying box, ensuring that the hot airflow evenly covers the canvas surface and improving drying efficiency. The collection box adopts a sliding connection design, facilitating quick removal and cleaning of waste liquid after drying, reducing subsequent maintenance time and preventing waste liquid accumulation from affecting the normal operation of the equipment.

[0013] 3. This utility model adopts an independent installation method for key components such as stepper motors, bidirectional lead screws, and rotating lead screws, and connects them through easily detachable structures such as couplings and nuts. When components are worn or malfunction, maintenance and replacement can be carried out without disassembling the entire equipment, reducing maintenance difficulty and cost. The operation panel connects to various electrical devices through control lines, and can accurately adjust the heating temperature, fan speed, and canvas conveying speed according to the drying process requirements of different canvases, making it suitable for processing scenarios of various specifications of canvases.

The drying process can lead to contamination of the canvas. A first filter screen 5 is installed on the top surface of the air duct 4 to prevent impurities in the outside air from entering the drying chamber 1 and contaminating the canvas being dried inside. A hinged door 6 is connected to the other side of the front end of the drying chamber 1, which facilitates the installation of the canvas before drying. An operation panel 7 is installed on one side of the front end of the switch door 6, which allows for the control of the electrical equipment installed in the drying chamber 1 via control lines.

[0018] In this invention, a bidirectional lead screw 11 is rotatably connected in the first sliding groove. The top surface of the bidirectional lead screw 11 passes through the first rotating hole. The bidirectional lead screw 11 facilitates the threaded connection of the pressing roller 14 and drives the pressing roller 14 to move towards or relative to each other to meet the process requirements of different canvases.

The two pressure rollers 14 are driven by a stepper motor 12 to move towards and relative to each other using a bidirectional screw 11. A first fan 16 is installed inside each of the two air ducts 4 to facilitate the discharge of hot exhaust gas from the drying chamber 1. The drying assembly includes a connecting collection chamber 28 and is installed in... The drying chamber 19 is located at the lower rear end of the drying chamber 1. The second positioning block 24 is easily fixed via welding. An air supply box 20 is vertically installed at the front top of the drying chamber 19. The air supply box 20 facilitates the installation of the second filter screen 21 via external bolts and the fixing of the first positioning block 22 via welding. The second filter screen 21 is installed on the top surface of the air supply box 20, facilitating the filtering of impurities from the outside air. First positioning blocks 22 are installed on both sides of the inner cavity of the air supply box 20, facilitating the locking and fixing of the second fan 23. The second fan 23 is installed between the inner walls of the first positioning blocks 22, facilitating the connection between the second fan and the air supply box 20. The connecting pipe connected to 0 supplies air to the drying chamber 19; and the connecting pipe is installed at the rear end of the top surface of the drying chamber 19; the other end of the connecting pipe is connected to the lower rear end of the air supply box 20. The four corners of the inner cavity of the drying chamber 19 are equipped with second positioning blocks 24 made of high temperature resistant material. The second positioning blocks 24 facilitate the subsequent snap-fit ​​installation of the heating tube 25. The second positioning blocks 24 are made of high temperature resistant material to prevent the high temperature of the heating tube 25 from affecting the structural strength of the second positioning blocks 24. The heating tube 25 is installed inside the second positioning block 24. The heating tube 25 facilitates the heating of the inside of the drying chamber 19. The air from the second fan 23 is used to send the hot air through the collection chamber 28 to the drying chamber 27 to dry the canvas.

[0019] Working principle: When using this utility model, place the drying box 1 and the support platform 2 on the designed base surface, and then slide the collection box 3 between the support platform 2 and the drying box 1. Then, turn on the power to the device. First, click on the operation screen 7 to start the equipment, open the switch door 6, and pass the canvas to be dried through the feed port of the drying chamber 1 between the two pressing rollers 14. Then, pass the canvas through multiple internal guide rollers 15 and pull it out through the discharge port of the drying chamber 1, connecting it to the external winding assembly. The operator rotates the external rotating screw 13 to adjust the guide rollers 15 located between the second positioning tables 10. Then, click on the operation screen 7 to select the corresponding process program and start the stepper motor 12. The stepper motor 12 will drive the bidirectional screw 11 to rotate. The pressing rollers 14 between the first positioning tables 9 will move in opposite directions to limit the movement of the canvas (during the installation of the canvas, the liquid contained in the canvas will pass through the partition plate 8 to the collection chamber 28, and then through the collection chamber 28 to the bottom of the drying box 1 and into the collection box 3). After the above steps are completed, the system will automatically shut down the stepper motor 12, and the operator will manually close the switch door 6 (the heat insulation plate 26 installed at the rear end of the switch door 6 will prevent the switch door 6 from overheating and reduce damage to the operator and prevent damage to the operation panel 7). Then, the first fan 16 and the second fan will be started through the operation panel 7. 23 and heating tube 25, the heating tube 25 fixed by the second positioning block 24 heats the internal temperature to the predetermined temperature. Due to the inverted plate design of the partition plate 8, the air in the air supply box 20 driven by the first positioning block 22 drives the hot air generated in the drying box 19 through the partition plate 8, generating a vortex that further increases the temperature in the collection chamber 28. At the same time, because the first fan 16 in the fan 4 exhausts the air in the drying chamber 27, the air pressure in the drying chamber 27 is too low, forcibly driving the hot air in the collection chamber 28 into the drying chamber 27 to dry the canvas. Located in the air supply box 20 The second filter 21 on the top surface and the first filter 5 on the top surface of the air duct 4 will prevent impurities in the air from entering the drying chamber 1. During the winding process of the canvas by the external winding assembly, the laser sensor 18 on the speed limiting platform 17 will measure the speed of the canvas. When the moving speed of the canvas differs too much from that of the external testing instrument, the stepper motor 12 will be activated to reduce the pressure on the canvas and ensure that the canvas will not be torn by force, thus preventing the canvas from breaking. After a canvas is dried, the collection box 3 is pulled out, the waste liquid is poured out, and the collection box 3 is reset. The above steps can be repeated to dry the next batch of canvas. During prolonged high-temperature use, the lubricating oil applied to the exterior of the bidirectional lead screw 11 and the rotating lead screw 13 will decrease. Therefore, lubricating oil should be added to the bidirectional lead screw 11 and the rotating lead screw 13 after a certain period of use (referred to as "oiling") to prevent component damage. After the equipment is powered off, the operator can open the switch door 6 to oil the bidirectional lead screw 11 and the rotating lead screw 13. After oiling, if there are specific requirements, the interior of the drying chamber 1 can also be cleaned directly using an external water pipe.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
