[0029] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings;

[0030] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] refer to Figure 1-4 A drying device for PVC sheet production includes a PVC sheet drying chamber 3. A fixed base 4 is fixedly installed on the bottom inner wall of the PVC sheet drying chamber 3. A first electric telescopic rod 5 is fixedly installed on the top of the PVC sheet drying chamber 3. A lifting seat 6 is fixedly installed at the output end of the first electric telescopic rod 5. A moisture discharge pipe is provided on the top of the lifting seat 6. The moisture discharge pipe is located inside the PVC sheet drying chamber 3. The moisture mixes with hot air to form water vapor. The high-temperature gas is discharged through the moisture discharge pipe after rising, preventing the water vapor from condensing and dripping back onto the sheet. Multiple rain shields 7 are fixedly installed between the front and rear inner walls of the fixed base 4. Fixed plates 8 are fixedly installed on the front left and right sides of the fixed base 4 and the lifting seat 6. A sheet conveying assembly 1 is provided above the fixed base 4, the lifting seat 6 and the fixed plates 8. A sheet drying assembly 2 is provided above the PVC sheet drying chamber 3.

[0032] In this embodiment, the sheet material conveying assembly 1 includes a motor 11, a worm gear 12, a movable shaft 13, a worm wheel 14, a sheet material conveying roller 15, a cleaning scraper 16, a hot air blower 17, an air outlet nozzle 18, and a connecting pipe 19. The motor 11 is fixedly installed on one side of the fixed plate 8, the worm gear 12 is fixedly installed on the output end of the motor 11, the movable shaft 13 is rotatably installed on the inner side of the fixed base 4 and the lifting seat 6, and is arranged sequentially from left to right, the worm wheel 14 is fixedly installed on the outer side of the movable shaft 13, and the worm gear 12 meshes with the worm wheel 14, the sheet material conveying roller 15 is fixedly installed on the outer side of the movable shaft 13, the cleaning scraper 16 is fixedly installed between the inner walls of the front and rear sides of the fixed base 4 and the lifting seat 6, and is arranged sequentially from left to right, the hot air blower 17 is installed on the top and front side of the PVC sheet material drying box 3, the air outlet nozzle 18 is fixedly installed on the inner side of the fixed base 4 and the lifting seat 6, and the connecting pipe 19 is fixedly installed on one side of the hot air blower 17, with one end of the connecting pipe 19 fixedly installed on one side of the air outlet nozzle 18.

[0033] In this embodiment, the board drying assembly 2 includes a mounting frame 21, springs 22, a downward sealing plate 23, a support plate 24, a second electric telescopic rod 25, and a hot air sealing plate 26. The mounting frame 21 is fixedly installed on the left side of the PVC board drying box 3. Multiple springs 22 are fixedly installed on the bottom inner wall of the mounting frame 21. The downward sealing plate 23 is fixedly installed on the top of the springs 22. The support plate 24 is fixedly installed on the right side of the PVC board drying box 3. The second electric telescopic rod 25 is fixedly installed on the front and rear sides of the top of the support plate 24. The hot air sealing plate 26 is fixedly installed on the output end of the second electric telescopic rod 25.

[0034] In this embodiment, the bottom of the fixed base 4 is provided with a ramp, and the bottom of the fixed base 4 is provided with a drainage pipe; so that water can flow into the inside of the drainage pipe through the ramp, so that the device does not require the staff to manually clean and discharge the water.

[0035] In this embodiment, the rain shield 7 is triangular in shape, and an installation groove is provided on one side of the rain shield 7. The air outlet nozzle 18 is located inside the installation groove. The installation groove facilitates the installation of the air outlet nozzle 18, and the triangular shape of the rain shield 7 makes it easier to prevent water from dripping onto the air outlet nozzle 18.

[0036] In this embodiment, the material of the sheet material conveying roller 15 is rubber, and the outer side of the sheet material conveying roller 15 is provided with anti-slip texture; both the rubber material and the anti-slip texture enable the sheet material conveying roller 15 to drive the sheet material to be conveyed after rotation, so that the sheet material does not need to be manually operated and conveyed by the staff during the drying process.

[0037] In this embodiment, the cleaning scraper 16 is attached to the board conveying roller 15, and the cleaning scraper 16 is triangular in shape. The triangular scraper makes it easy to scrape away the water flow above the board conveying roller 15, and water stains are not easily left on the top of the cleaning scraper 16, so that the board conveying roller 15 does not easily make the dry board wet.

[0038] In this embodiment, through slots are provided on the left and right sides of the PVC sheet drying oven 3. The length and width of the pressure sealing plate 23 and the hot air sealing plate 26 are both greater than the length and width of the through slots. This allows the pressure sealing plate 23 and the hot air sealing plate 26 to seal the through slots after they are moved, making it less likely for hot air to leak inside the PVC sheet drying oven 3. This means that the next batch of sheets does not need to wait for a long heating process when drying.

[0039] Specifically, after the sheet material is added above the lower sheet material conveying roller 15, the first electric telescopic rod 5 is controlled to lower the lifting seat 6 according to the thickness of the sheet material, so that the sheet material conveying roller 15 on the upper lifting seat 6 abuts against the upper surface of the sheet material. The motor 11 is controlled to drive the worm gear 12 to rotate, so that the worm gear 12 can drive the movable shaft 13 to rotate through the worm wheel 14. After the movable shaft 13 rotates, it can drive the sheet material conveying roller 15 to convey the sheet material. During the conveying process, the hot air blower 17 is turned on, so that the hot air blower 17 transmits hot air to the air outlet nozzle 18 through the connecting pipe 19, so that the air outlet nozzle 18 can exhaust the hot air inside the fixed base 4 and the lifting seat 6, and the rain shield 7 below makes it difficult for liquid on the top of the sheet material to drip. Above the air nozzle 18, liquid can be collected and discharged via the lower slope. During the drying process of the board, the motor 11 can be controlled to rotate repeatedly, thereby controlling the residence time of the board inside the PVC board drying chamber 3. After drying, the second electric telescopic rod 25 can be controlled to drive the hot air sealing plate 26 to rise, so that the board conveying roller 15 can convey and move the board out. When it is necessary to feed the next board, the board can be placed on the top of the pressing sealing plate 23. Pressing the pressing sealing plate 23 opens the through groove on the left side of the PVC board drying chamber 3, allowing the board to enter the inside of the PVC board drying chamber 3 for drying. After conveying, the spring 22 can drive the pressing sealing plate 23 to rise and seal the through groove.
