Description

Technical Field

[0001] This utility model belongs to the field of photosensitive drum processing technology, specifically relating to a photosensitive drum processing coating and drying device. Background Technology

[0002] Traditional photosensitive drum processing coating and drying methods have many shortcomings. For photosensitive drums of different sizes, the fixed structure cannot be flexibly adjusted to adapt to different specifications. This not only increases production costs but also reduces production efficiency. Furthermore, during the drying process, it is often difficult to achieve uniform heating, resulting in inconsistent drying of the coating on the surface of the photosensitive drum and affecting product quality.

[0003] Chinese Patent CN219334847U discloses a photosensitive drum coating and drying device, which solves the problem in existing technologies where it is difficult to distribute hot air evenly in the drying chamber during the drying process, thus greatly reducing the uniformity of all photosensitive drum materials during drying. The photosensitive drum coating and drying device includes a chamber with several support filter plates fixedly connected vertically along the inner side of the chamber. A hot air blower is bolted to one side of the outer wall of the chamber, and an air outlet hood is fixedly connected to one side of the inner wall of the chamber, with the air outlet of the hot air blower connected to one side of the air outlet hood. The proposed method utilizes the support filter plates to allow drying even at the bottom of the material, while the rotation of two fans improves the airflow rate and uniformity within the chamber.

[0004] During use, the aforementioned patented device cannot effectively fix photosensitive drums of different sizes, which may cause the photosensitive drums to be blown by the fan, thereby reducing the versatility of the device and affecting the drying quality. Furthermore, during the drying process, the photosensitive drums closer to the air outlet are heated more, while those farther away from the air outlet are heated less, thus reducing the uniformity and stability of the drying effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-6As shown, this utility model provides a photosensitive drum processing coating and drying device, including a box body 1, a box door 4 movably connected to one side of the box body 1, two arc-shaped heat preservation plates 5 symmetrically installed inside the box body 1, and several bearing turntables 26 arranged on opposite sides of the arc-shaped heat preservation plates 5. The box body 1 includes a rotating mechanism 2 for rotating the product, a drying mechanism 3 for conveying hot air, and an adjustment mechanism 8 for adapting to different product sizes.

[0027] The top of the turntable 26 is fixedly connected to several fixed blocks 81. A photosensitive drum 6 is fitted onto the outer surface of each fixed block 81. A slide rod 82 is slidably connected to the lower end of each fixed block 81. Several first U-shaped frames 83 are fixedly connected to the top of the slide rod 82. A connecting rod 84 is movably connected inside each first U-shaped frame 83. The top of the connecting rod 84 is movably connected to the inside of a second U-shaped frame 85. A locking block 86 is fixedly connected to one side of the second U-shaped frame 85. The locking block 86 is movably connected to the upper slot of the fixed block 81. The bottom end of the locking block 86 is in contact with the inner surface of the photosensitive drum 6.

[0028] The bottom end of the slide rod 82 passes through the inside of the bearing turntable 26 and is fixedly connected to a semi-circular plate 88. A spring 87 is sleeved on the outer surface of the bottom end of the slide rod 82.

[0029] In this embodiment, when different sizes of photosensitive drums 6 need to be dried, the photosensitive drum 6 is fitted onto the outer surface of the fixing block 81 on the top of the carrying turntable 26. During the fitting process, the inner surface of the photosensitive drum 6 exerts pressure on the locking block 86, causing the locking block 86 to rotate on the upper end of the inner wall of the fixing block 81 under the fixation of its internal screw. The locking block 86 drives the connecting rod 84 to move upward through the second U-shaped frame 85. At the same time as the connecting rod 84 moves, it drives the sliding rod 82 to slide upward through the first U-shaped frame 83. The sliding rod 82 drives the semi-circular plate 88 to move upward and compresses the spring 87. While the spring 87 is compressed, its elasticity provides a certain restoring force to the sliding rod 82, so that the bottom end of the locking block 86 is always in contact with the inner surface of the photosensitive drum 6 during the rotation process. This adapts to different sizes of photosensitive drums 6, realizes stable fixation of photosensitive drums 6 of different specifications, improves the versatility of the device, ensures that the photosensitive drum 6 will not be displaced or shaken during rotation and drying, and improves the drying quality.

[0030] In a further embodiment, the semicircular plate 88 is symmetrically arranged around the axis of the bearing turntable 26, the top end of the spring 87 is fixedly connected to the bottom of the bearing turntable 26, and the bottom end of the spring 87 is fixedly connected to the top of the semicircular plate 88.

[0031] In this embodiment, the semicircular plates 88 are symmetrically arranged during the disassembly process. The workers can use the semicircular plates 88 to remove the photosensitive drums 6 on the carrier turntable 26 in batches, making the operation more efficient and convenient. The spring 87 plays an auxiliary role in resetting. When the photosensitive drum 6 is installed, as the photosensitive drum 6 is fitted onto the fixing block 81, the slide rod 82 moves downward and compresses the spring 87. The moderate elasticity of the spring 87 provides a continuous fixing force for the locking block 86.

[0032] In a further embodiment, a motor 21 is fixedly installed at one end of the top of the housing 1, and a small pulley 22 is fixedly sleeved on the output shaft of the motor 21. The small pulley 22 is rotatably connected to the top of the housing 1.

[0033] In this embodiment, after the motor 21 starts, its output shaft drives the small pulley 22 to rotate. The small pulley 22 transmits the power generated by the motor 21 to the subsequent transmission system, thereby driving the operation of various mechanisms in the device.

[0034] In a further embodiment, a belt 23 is meshed on the outer surface of the small pulley 22, and a large pulley 24 is meshed on one end of the belt 23. A drive shaft 25 is fixedly sleeved inside the large pulley 24. The bottom end of the drive shaft 25 passes through the top wall of the housing 1 and extends to the bottom wall of the housing 1. Several bearing turntables 26 are fixedly connected to the outer surface of the drive shaft 25.

[0035] In this embodiment, after the motor 21 starts, it drives the small pulley 22 to rotate. The small pulley 22 transmits power to the large pulley 24 through the belt 23. The large pulley 24 drives the transmission shaft 25 to rotate. While the transmission shaft 25 rotates, the several bearing turntables 26 connected to the outer surface rotate accordingly. The bearing turntables 26 drive the photosensitive drum 6 to continuously change position during the drying process through the fixing block 81, ensuring that all parts of the photosensitive drum 6 can be evenly contacted by hot air, thus ensuring the uniformity and stability of the drying effect.

[0036] In a further embodiment, a hot air blower 31 is fixedly installed at the other end of the top of the housing 1, and a main air duct 32 is fixedly connected to the end of the inner wall of the housing 1 near the hot air blower 31. The top end of the main air duct 32 passes through the top wall of the housing 1 and is fixedly connected to the air outlet of the hot air blower 31.

[0037] In this embodiment, the hot air blower 31 can continuously deliver hot air to provide the heat required for drying the photosensitive drum 6. The main air duct 32 serves as the hot air delivery channel, guiding the hot air generated by the hot air blower 31 into the housing 1.

[0038] In a further embodiment, a branch pipe 33 is fixedly connected to the bottom end of the main air duct 32, and a secondary air duct 34 is fixedly connected to both ends of the branch pipe 33. One end of the secondary air duct 34 passes through the middle of the arc-shaped insulation board 5 at the same end.

[0039] In this embodiment, hot air flows into the diversion pipe 33 through the main air duct 32. The diversion pipe 33 splits the hot air, so that the hot air flows to the auxiliary air ducts 34 at both ends. The hot air enters the channel inside the arc-shaped heat preservation plate 5 through the auxiliary air duct 34 and blows towards the area where the photosensitive drum 6 is located. This allows the hot air to blow onto the photosensitive drum 6 from two directions at the same time, increasing the contact area and contact opportunities between the hot air and the photosensitive drum 6, and improving the uniformity of drying.

[0040] In a further embodiment, a number of air outlet pipes 7 are fixedly connected to the bottom of the other end of the box 1, and one end of the air outlet pipe 7 passes through the bottom of the arc-shaped insulation board 5 at the adjacent end.

[0041] In this embodiment, after the hot air dries the photosensitive drum 6, the hot air carrying moisture is discharged through the air outlet 7, creating space for new hot air to enter the chamber 1, ensuring continuous air renewal during the drying process and improving drying efficiency.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
