Description
Technical Field
[0001] This utility model relates to the field of oil canvas technology, and in particular to a novel oil canvas drying device. Background Technology
[0002] Oil painting is a type of painting that uses quick-drying vegetable oils (linseed oil, walnut oil, etc.) to mix pigments and then paints on canvas, linen, cardboard, or wood panels. The thinners used in painting are volatile turpentine and drying linseed oil, etc. The pigments adhering to the surface have a strong hardness, and once the painting dries, it can maintain its luster for a long time.
[0003] The use of canvas is essential in the oil painting process. During the production and processing of canvas, drying is necessary. However, most commonly used canvas drying devices have relatively simple structures, resulting in uneven drying and reduced efficiency. Furthermore, existing canvas drying devices generally lack dust prevention, allowing dust and other impurities to enter the drying chamber with the airflow during drying. These dust and impurities accumulate on the surface of the canvas and dry along with it, significantly degrading the quality of the finished painting. To address these issues, a solution is proposed below. Utility Model Content
[0004] The purpose of this invention is to provide a novel oil canvas drying device, which has the advantages of good dust prevention and high drying efficiency.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A novel canvas drying device includes a base, a drying chamber, and a canvas body. The drying chamber is fixed to the upper part of the base. A hot air mechanism is installed inside the base. An air inlet slot is opened at the front end of the base. Two retaining seats are fixed at the front end of the base, and a filter sheet is engaged between the two retaining seats. The filter sheet is located at the front end of the air inlet slot. A protruding post is fixed to the inner top of the base, and a guide platform with an arc shape is fixed to the lower end of the protruding post. A ventilation hole is opened at the upper end of the base, and the ventilation hole extends to the drying chamber and communicates with the interior of the drying chamber. The drying oven has two air-gathering boxes fixed to its inner wall. A ventilation pipe is connected between the air-gathering boxes and the ventilation holes. Several air-gathering plates are fixed inside each air-gathering box. Several air outlets are opened on the surface of the air-gathering boxes. A rotating seat is fixed to the bottom of the drying oven. A rotating shaft is rotatably connected to the upper end of the rotating seat. Several shelves are connected to the upper end of the rotating shaft. Several connecting columns are connected between every two shelves. A fixing mechanism is provided on the shelves. An air outlet pipe is connected to the top of the drying oven. A removable filter screen is installed inside the air outlet pipe.
[0007] Preferably, the hot air mechanism includes several electric heating tubes installed inside the base, a motor is installed at the bottom inner side of the base, the output shaft of the motor is fixed with fan blades, and the fan blades are located below the several electric heating tubes.
[0008] Preferably, the fixing mechanism includes a fixing block, a mounting base is fixedly provided on the inner side of the shelf, two rotatable threaded rods are inserted through the mounting base, the threads of the two threaded rods are in opposite directions and one end is fixedly connected, a rotating block is provided on one side of the shelf, and one end of the threaded rod is fixedly connected to the rotating block, a support net is also fixedly provided on the inner side of the shelf, the support net is flush with the upper surface of the mounting base, threaded seats are respectively inserted on the two threaded rods, a torsion spring is connected to the upper end of the threaded seat, and the fixing block is fixedly connected to the other end of the torsion spring, the canvas body is fixed to the lower end of the two fixing blocks, and the lower end surface is in contact with the upper surface of the support net.
[0009] Preferably, the air outlet pipe is provided with several fixing pins, the top ends of the fixing pins are respectively inserted into the filter screen, and each fixing pin is provided with a return spring, and the two ends of the return spring are connected between the tail end of the fixing pin and the outer wall of the air outlet pipe.
[0010] Preferably, the front end of the drying oven is provided with a double-opening door, and the lower end of the base is equipped with several casters.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. The filter can prevent dust and other impurities in the air from entering the base, thus preventing dust from adhering to the surface of the canvas during drying. Therefore, it can play a dustproof role and improve the drying quality of the canvas. The filter can further prevent dust and other impurities from entering the drying chamber through the air outlet pipe. At the same time, it can also exhaust excess heat in the drying chamber through the air outlet pipe during drying to ensure airflow.
[0013] 2. By rotating the shelf and using a fixing mechanism, the canvas can be fixed on the shelf for drying. Similarly, canvases of different sizes can be fixed, thus greatly increasing the application range of the drying device and facilitating its widespread use. Several electric heating tubes generate heat, and the motor drives the fan blades to rotate, generating hot airflow inside the base and blowing it out. The guide platform guides the hot airflow, allowing it to flow more quickly and evenly into the ventilation holes. The hot airflow is then blown through the ventilation pipe into the air-collecting box, where several air-collecting plates further guide the airflow, ensuring it is blown out more evenly from the air outlets. This results in a more uniform heat distribution inside the drying chamber, allowing for even drying of the canvas on the shelf and further improving the drying efficiency.

[0021] like Figures 1 to 5 As shown, a novel canvas drying device includes a base 1, a drying chamber 2, and a canvas body 3. The drying chamber 2 is fixed on the upper end of the base 1. The front end of the drying chamber 2 is provided with a double-opening door 33. Several casters 34 are installed at the lower end of the base 1. The canvas can be placed into the drying chamber 2 for drying by opening the door 33. The casters 34 also facilitate the movement and fixation of the entire device. An air inlet slot is provided at the front end of the base 1, and two retaining seats 5 are fixedly provided at the front end of the base 1. A filter 6 is snapped between the two retaining seats 5, and the filter 6 is located at the front end of the air inlet slot. The filter 6 can prevent dust and other impurities in the air from entering the base 1, thereby preventing dust from adhering to the surface of the canvas during drying. Therefore, it can play a dustproof role and improve the drying quality of the canvas. When there are many impurities attached to the filter 6, the filter 6 can be removed from the two retaining seats 5 for cleaning. After that, the two ends of the filter screen 20 can be snapped back into the two retaining seats 5 to achieve fixed installation of the filter 6.
[0022] The top of the drying chamber 2 is connected to an air outlet pipe 19, and a removable filter screen 20 is installed inside the air outlet pipe 19. The filter screen 20 can further prevent dust and other impurities from entering the drying chamber 2 through the air outlet pipe 19. At the same time, during the drying process, excess heat in the drying chamber 2 can be discharged through the air outlet pipe 19 to ensure airflow. Several fixing pins 31 are installed on the air outlet duct 19. The top ends of the fixing pins 31 are respectively inserted into the filter screen 20. Each fixing pin 31 is equipped with a return spring 32, and the two ends of the return spring 32 are connected between the tail end of the fixing pin 31 and the outer wall of the air outlet duct 19. When the filter screen 20 is covered with a lot of dust and other impurities, the fixing pins 31 can be pulled to dislodge the top ends of the fixing pins 31 from the filter screen 20. At this time, the return spring 32 is stretched and generates elastic force, and then the filter screen 20 can be removed for cleaning. Afterwards, the filter screen 20 can be installed back in its initial position, and the return spring 32 will drive the fixing pins 31 back to their initial position, so that the top ends of the fixing pins 31 can be pushed back into the filter screen 20, thereby achieving the fixed installation of the filter screen 20.
[0023] A rotating seat 14 is fixedly installed at the bottom of the drying oven 2. A rotating shaft 15 is rotatably connected to the upper end of the rotating seat 14. Several shelves 16 are connected to the upper end of the rotating shaft 15. Several connecting columns 17 are connected between every two shelves 16. A fixing mechanism 18 is provided on the shelf 16. By rotating the angle of the shelf 16 and fixing it through the fixing mechanism 18, the canvas can be fixed on the shelf 16 for drying. The fixing mechanism 18 includes a fixing block 24. A mounting base 25 is fixedly provided on the inner side of the shelf 16. Two rotatable threaded rods 26 are inserted through the mounting base 25. The threads of the two threaded rods 26 are opposite in direction and one end is fixedly connected. A rotating block 27 is provided on one side of the shelf 16, and one end of the threaded rod 26 is fixedly connected to the rotating block 27. Threaded seats 29 are respectively inserted on the two threaded rods 26. By rotating the rotating block 27, the two threaded rods 26 can be rotated simultaneously. Since the threads of the two threaded rods 26 are opposite in direction, the two threaded seats 29 can move away from or closer to each other along the two threaded rods 26, and the distance between the two threaded seats 29 can be adjusted.
[0024] A support net 28 is fixedly installed on the inner side of the shelf 16. The support net 28 is flush with the upper surface of the mounting base 25. A torsion spring 30 is connected to the upper end of the threaded seat 29, and the fixing block 24 is fixedly connected to the other end of the torsion spring 30. The canvas body 3 is fixed to the lower end of the two fixing blocks 24, and the lower end face is in contact with the upper surface of the support net 28. The operator can place the canvas to be dried on the upper surface of the support net 28 and adjust the position of the two fixing blocks 24 by adjusting the position of the two threaded seats 29. Then, the pressure block is pushed upward so that the pressure block is located above the two sides of the canvas. At this time, the torsion spring 30 is deformed and generates elastic force. Then, the pressure block is driven back to the initial position by the reset action of the torsion spring 30, so that the pressure block can press the upper ends of the two sides of the canvas, thereby fixing the canvas. Similarly, canvases of different sizes can be fixed, thus greatly increasing the application range of the drying device and facilitating its widespread use.
[0025] A hot air mechanism 4 is installed inside the base 1, which generates hot airflow. The hot air mechanism 4 includes several electric heating tubes 21 installed inside the base 1. A motor 22 is installed at the bottom inner side of the base 1. The output shaft of the motor 22 is fixed with a fan blade 23, which is located below the electric heating tubes 21. Heat is generated by the operation of the electric heating tubes 21, and the rotation of the motor 22 drives the fan blade 23 to rotate, thereby generating hot airflow inside the base 1 and blowing the hot airflow. The structure and operation of the electric heating tubes 21 are existing technologies and will not be described in detail.
[0026] A protruding post 7 is fixedly provided on the inner top of the base 1. A guide platform 8 is fixedly provided at the lower end of the protruding post 7, and the guide platform 8 is arc-shaped. A ventilation hole 9 is provided at the upper end of the base 1, extending to the drying chamber 2 and communicating with the interior of the drying chamber 2. Two air-gathering boxes 10 are fixedly provided on the inner wall of the drying chamber 2. A ventilation pipe 11 is connected between the air-gathering box 10 and the ventilation hole 9. Several air-gathering plates 12 are fixedly provided in each air-gathering box 10. Several air outlets 13 are provided on the surface of the air-gathering box 10. The heat can be directed through the guide platform 8. The airflow acts as a guide, allowing the hot airflow to flow more quickly and evenly into the ventilation hole 9. Subsequently, the hot airflow can be blown into the air-collecting box 10 through the ventilation pipe 11. At this time, several air-collecting plates 12 can guide the hot airflow again, making the hot airflow blown out from several air outlets 13 more evenly. Therefore, the heat distribution inside the drying chamber 2 can be more uniform, thereby drying the canvas body 3 on the shelf 16 evenly and further improving the drying efficiency of the canvas.
