Description

Technical Field

[0001] This utility model relates to the field of plastic sheet production, and in particular to a dehumidification and drying equipment for plastic sheet production. Background Technology

[0002] Plastic sheets, as a lightweight and versatile material, play an indispensable role in our daily lives. Their applications are extremely widespread, spanning packaging, electronics, home furnishings, and many other fields. However, to ensure the quality and performance of plastic sheets, a crucial step in their production process is dehumidification and drying. This step not only effectively removes excess moisture from the plastic sheets, preventing deformation and cracking during subsequent processing or use, but also improves their physical properties and stability, ensuring the final product meets expected standards. Therefore, the dehumidification and drying process is particularly important on plastic sheet production lines and is key to ensuring product quality.

[0003] In daily work, it has been found that during the drying process of plastic sheets, due to the limitations of the drying equipment, uneven drying often occurs. Specifically, the top part of the plastic sheet is already dry, while the bottom part remains wet. This situation, where the top is dry but the bottom is not, greatly affects the quality of the plastic sheet and the efficiency of subsequent processing. The frequent occurrence of this situation not only prolongs the drying time but may also cause the plastic sheet to deform or be damaged due to uneven heating. In severe cases, it may even affect the smooth operation of the entire production process. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the drying process of plastic sheets, due to the limitations of the drying equipment, the plastic sheets often dry unevenly during drying; specifically, the top part of the plastic sheet is dry, while the bottom part remains moist. Therefore, this invention proposes a dehumidifying and drying device for the production of plastic sheets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dehumidifying and drying equipment for the production of plastic sheets, comprising a frame, a dryer for drying plastic sheets is fixedly installed on the top of the frame, two pairs of fixing plates are fixedly installed on the top of the frame, a flipping component is provided in the middle of the two pairs of fixing plates, and two air volume adjustment components are provided at the bottom of the dryer.

[0006] The flipping assembly includes a first plate, a second plate, a receiving rod, and a support plate. There are two first plates, which are symmetrically installed on the surface of the frame. The second plate is fixedly installed on one side of the first plate on the surface of the frame. The support plate is located on the top of the second plate. The receiving rod is fixedly installed at the joint of the two support plates.

[0007] As a further embodiment of this utility model, a drive roller is rotatably connected to the joint of a pair of fixed plates, and a first motor is fixedly installed on the side of the fixed plate away from the drive roller. The drive roller is fixedly installed at the output end of the first motor. A driven roller is rotatably connected to the joint of another pair of fixed plates, and a conveyor belt for transporting plastic sheets is drivenly connected to the surfaces of the drive roller and the driven roller.

[0008] As a further embodiment of this utility model, a limiting block is fixedly installed on the top of the pallet, and a first rotating shaft is fixedly installed on the side of the pallet, the first rotating shaft being rotatably connected to the end of the first plate.

[0009] As a further embodiment of this utility model, a groove is provided on the top of the second plate, and a slider is fixedly installed on the bottom of the support plate, with the slider slidably connected to the surface of the groove.

[0010] As a further embodiment of this utility model, a third plate is provided on one side of the first plate, a second motor is fixedly installed on one side of the third plate, and a first connecting rod is rotatably connected to the other side of the third plate. The output end of the second motor is fixedly connected to the first connecting rod, and a second connecting rod is rotatably connected to the end of the first connecting rod. The end of the second connecting rod is rotatably connected to the bottom of the support plate.

[0011] As a further embodiment of this utility model, the air volume regulating component includes a housing, a fixed column, three or more blades, and a slip ring. The housing is fixedly installed at the air outlet at the bottom of the dryer. The fixed column is fixedly connected to the inner wall of the housing. One end of each blade is rotatably connected to the side of the fixed column, and the other end is rotatably connected to the inner wall of the housing. The slip ring is rotatably connected to the circumferential surface of the outer wall of the housing.

[0012] As a further embodiment of this utility model, a driving block is fixedly connected to the end of the blade away from the fixed column, a driving groove is formed on the surface of the driving block, three or more second rotating shafts are rotatably connected to the circumferential surface of the slip ring, the second rotating shafts are slidably connected to the surface of the driving groove, and a push rod is fixedly connected to the end of the slip ring.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, a second motor drives a first connecting rod to deflect, which in turn drives a second connecting rod to push a pallet. Under the limiting action of a first rotating shaft, the pallet flips, thus achieving the flipping operation of the plastic sheet. This facilitates the drying of the bottom of the plastic sheet by the dryer, preventing the bottom of the plastic sheet from remaining undried. Furthermore, pushing the push rod causes the slip ring to rotate along the surface of the housing. The second rotating shaft on the surface of the slip ring pushes the drive groove, thereby causing the drive block to rotate. Since the drive block is fixedly connected to the blades, the blades will flip, thus changing the airflow. When the raw material has a high moisture content in the early stage of drying, the blade angle can be increased to increase the airflow and quickly remove moisture. In the later stage, the angle can be reduced to maintain a low wind speed for heat preservation and drying, reducing ineffective energy consumption. Attached Figure Description

Detailed Implementation

[0021] Please see Figure 1-5This utility model provides a technical solution: a dehumidification and drying equipment for the production of plastic sheets, including a frame 1, a dryer 2 for drying plastic sheets is fixedly installed on the top of the frame 1, two pairs of fixing plates 3 are fixedly installed on the top of the frame 1, a flipping component 4 is provided in the middle of the two pairs of fixing plates 3, and two air volume adjustment components 5 are provided at the bottom of the dryer 2.

[0022] In this embodiment: the flipping assembly 4 includes a first plate 41, a second plate 42, a receiving rod 43 and a tray 45. There are two first plates 41, which are symmetrically installed on the surface of the frame 1. The second plate 42 is fixedly installed on one side of the first plate 41 on the surface of the frame 1. The tray 45 is located on the top of the second plate 42. The receiving rod 43 is fixedly installed at the joint of the two trays 45.

[0023] To flip the plastic sheet, please refer to [link / reference]. Figure 2-4 A pair of fixed plates 3 are rotatably connected to a drive roller 31 at their joints, and a first motor 34 is fixedly installed on the side of the fixed plate 3 away from the drive roller 31. The drive roller 31 is fixedly installed at the output end of the first motor 34. A driven roller 32 is rotatably connected to the joints of another pair of fixed plates 3. A conveyor belt 33 for transporting plastic sheets is connected to the surfaces of the drive roller 31 and the driven roller 32. The operator can drive the drive roller 31 to rotate by driving the first motor 34, and drive the conveyor belt 33 to move under the limiting transmission of the driven roller 32, thereby causing the plastic sheet placed on the surface of the conveyor belt 33 to move.

[0024] A limiting block 451 is fixedly installed on the top of the pallet 45. When the plastic sheet is conveyed by the conveyor belt 33, the plastic sheet will be brought to the surface of the pallet 45, and its end will abut against the limiting block 451. A first rotating shaft 452 is fixedly installed on the side of the pallet 45. The first rotating shaft 452 is rotatably connected to the end of the first plate 41. A third plate 44 is provided on one side of the first plate 41. A second motor 441 is fixedly installed on one side of the third plate 44, and a first connecting rod 442 is rotatably connected to the other side of the third plate 44. The output end of the second motor 441 is connected to the first connecting rod. A fixed connection is made between the first connecting rod 442 and the second connecting rod 443, which is rotatably connected to the end of the first connecting rod 442. The end of the second connecting rod 443 is rotatably connected to the bottom of the support plate 45. The second motor 441 drives the first connecting rod 442 to deflect, and the first connecting rod 442 drives the second connecting rod 443, causing the second connecting rod 443 to push the support plate 45. Under the limiting action of the first rotating shaft 452, the support plate 45 flips over, thereby realizing the flipping operation of the plastic sheet. This is beneficial for the dryer 2 to dry the bottom of the plastic sheet, avoiding the phenomenon that the bottom of the plastic sheet is not dried.

[0025] The second plate 42 has a groove 421 at the top, and a slider 453 is fixedly installed at the bottom of the support plate 45. The slider 453 is slidably connected to the surface of the groove 421. During the flipping process of the support plate 45, the slider 453 and the groove 421 always maintain a sliding engagement state, thereby providing assistance for the flipping of the support plate 45 to achieve a flipping with a larger load.

[0026] To change the airflow of dryer 2, please refer to [link / reference]. Figure 1 , 5 The air volume regulating component 5 includes a housing 51, a fixed column 52, three or more blades 53 and a slip ring 54. The housing 51 is fixedly installed at the air outlet at the bottom of the dryer 2. The fixed column 52 is fixedly connected to the inner wall of the housing 51. One end of the blade 53 is rotatably connected to the side of the fixed column 52, and the other end is rotatably connected to the inner wall of the housing 51. The slip ring 54 is rotatably connected to the circumferential surface of the outer wall of the housing 51.

[0027] A drive block 531 is fixedly connected to the end of blade 53 away from the fixed column 52. A drive groove 532 is opened on the surface of the drive block 531. Three or more second rotating shafts 541 are rotatably connected to the circumferential surface of the slip ring 54. The second rotating shafts 541 are slidably connected to the surface of the drive groove 532. A push rod 542 is fixedly connected to the end of the slip ring 54. The operator can push the push rod 542 to drive the slip ring 54 to rotate along the surface of the housing 51. The second rotating shafts 541 on the surface of the slip ring 54 will push the drive groove 532, thereby driving the drive block 531 to rotate. Since the drive block 531 is fixedly connected to the blade 53, the blade 53 will flip, thereby changing the air volume. When the raw material has a high moisture content in the early stage of drying, the angle of the blade 53 can be increased to increase the air volume and quickly remove the moisture. In the later stage, the angle can be reduced to maintain a low wind speed for heat preservation and drying, reducing ineffective energy consumption.

[0028] Working principle: The operator places the plastic sheet to be dried on the surface of the conveyor belt 33. The first motor 34 drives the active roller 31 to rotate, and under the limiting transmission of the driven roller 32, it drives the conveyor belt 33 to move, thereby displacing the plastic sheet placed on the surface of the conveyor belt 33. After the plastic sheet is conveyed by the conveyor belt 33, it will be carried to the surface of the pallet 45, and the end of the plastic sheet will abut against the limiting block 451. Next, the second motor 441 drives the first connecting rod 442 to deflect, and the first connecting rod 442 drives the second connecting rod 443, causing the second connecting rod 443 to push the pallet 45. Under the limiting action of the first rotating shaft 452, the pallet 45 flips, thereby realizing the drying of the plastic sheet. The flipping operation of the pallet 45 is carried out, and during the flipping process of the pallet 45, the slider 453 and the slide groove 421 always maintain a sliding engagement state, thereby providing assistance for the flipping of the pallet 45 to achieve a larger load flipping. In addition, the push rod 542 can be pushed to drive the slip ring 54 to rotate along the surface of the housing 51. The second rotating shaft 541 on the surface of the slip ring 54 will push the drive groove 532 to drive the drive block 531 to rotate. Since the drive block 531 is fixedly connected to the blade 53, the blade 53 will flip, thereby changing the air volume. When the raw material has a high moisture content in the early stage of drying, the angle of the blade 53 can be increased to increase the air volume and quickly remove the moisture. In the later stage, the angle can be reduced to maintain a low wind speed for heat preservation and drying, reducing ineffective energy consumption.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
