Description

Technical Field

[0001] This utility model relates to the field of optical guide drum manufacturing technology, and in particular to an apparatus for dipping an organic optical guide drum coating substrate. Background Technology

[0002] A photoconductor drum is a photoelectric conversion device formed by coating a photosensitive material onto the surface of a conductive aluminum tube. Its surface condition directly affects the use of a laser printing system. In the production of organic photoconductor drums, a photosensitive material needs to be coated onto the surface of the base tube to form a surface substrate.

[0003] Currently, in coating production, the base tube is usually placed in a basket and then placed in a dip coating device for dip coating. However, after dip coating is completed, the coating formed on the surface of the base tube is not completely dried and set. At this time, it is easy to damage the coating when the base tube is taken out of the basket. Waiting for the coating to dry will affect the subsequent dip coating production of the base tube, resulting in low overall dip coating processing efficiency.

[0004] To address these issues, we propose an organic light guide drum coating substrate dip-coating device. Utility Model Content

[0005] The purpose of this invention is to provide an organic light guide drum coating substrate dip coating device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An organic photoconductor drum coating substrate dip-coating device includes a dip-coating cylinder with a base fixed to the outside. A lifting frame is mounted on the base, and a lifting head is movably connected to the lifting frame via a support arm. The lifting head is used to insert into the port of the photoconductor drum and press firmly. A screw is rotatably connected to the lower part of the lifting head, and a chassis is rotatably connected to the bottom end of the screw. Three inner support rods are rotatably hinged to the periphery of the chassis. A threaded ring is screwed onto the external thread of the screw, and a connecting rod is hinged to each inner support rod corresponding to the threaded ring. A bevel gear ring is coaxially fixed to the end of the screw extending from the top of the lifting head, and a bevel gear is vertically meshed with the periphery of the bevel gear ring. A motor for driving the bevel gear to rotate is also mounted on the lifting head.

[0008] In a further embodiment, a lead screw and a slide rod are rotatably mounted in the lifting frame, and a motor for driving the lead screw to rotate is mounted on the lifting frame. The lead screw and slide rod are sleeved with a slider, and the slider is threadedly connected to the lead screw.

[0009] In a further embodiment, a support rod is also connected between the outer edge of the chassis and the lifting head.

[0010] In a further embodiment, an anti-slip pad is connected to the outer wall of the top end of the inner support rod.

[0011] In a further embodiment, the surface of the anti-slip pad is provided with air holes, and a thin tube communicating with the air holes is connected to the bottom of the anti-slip pad. The screw adopts a hollow structure, and the thin tube passes through the lower end of the screw to the upper end. The other end of the thin tube is connected to a rotary joint, and the rotary joint is also connected to an air pump through an air pipe.

[0012] In a further embodiment, the bottom end of the lifting frame is rotatably connected to the base via a turntable, and a motor for driving the turntable to rotate is also installed below the base.

[0013] In a further embodiment, an overflow pipe is connected to the upper side of the dip coating cylinder, and a liquid storage cylinder is provided below the overflow pipe. The bottom of the liquid storage cylinder is connected to the bottom of the dip coating cylinder through a water pump and a pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a lifting head where the rotating screw can open or retract the inner support rod, facilitating its insertion into the port of the photoconductor drum base tube. The support rod is then pressed against the inner ring of the base tube, and its lifting and lowering movement is controlled by a lifting frame. This allows the photoconductor drum to be dip-coated within the coating cylinder while being clamped by the lifting head. This makes it easy to remove the coated base tube, eliminating the need to wait for the coating to dry and maintaining the integrity of the coating on the base tube surface, thus improving the overall dipping efficiency of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] 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.

[0025] Please see Figure 1An organic photoconductor drum coating substrate dip-coating device includes a dip-coating cylinder 1 containing a photosensitive material solution. A base 2 is fixed to the outside of the dip-coating cylinder 1, and a lifting frame 3 is installed on the base 2. A lifting head 5 is movably connected to the lifting frame 3 via a support arm 4. The lifting head 5 is used to insert into the port of the photoconductor drum and press firmly, thereby clamping and fixing it from the inside of the base tube. This not only does not affect the substrate dip-coating on the outer surface, but also facilitates the movement of the base tube, making it easy to dip into or remove from the dip-coating cylinder 1.

[0026] Please see Figure 3 To facilitate control of the lifting head 5 to drive the base pipe to rise and fall, a lifting frame 3 is provided with a lead screw 31 and a slide rod 32 that are rotatably installed. A motor 33 that drives the lead screw 31 to rotate is installed on the lifting frame 3. A slider 34 is sleeved on the lead screw 31 and the slide rod 32, and the slider 34 is threadedly connected to the lead screw 31. The slider 34 is fixed to the support arm 4, so that when the lead screw 31 rotates, the slider 34 moves up and down along the lead screw 31 and the slide rod 32 under the limiting action of the slide rod 32.

[0027] Please see Figure 2 and Figure 4 A screw 51 is rotatably connected to the lower part of the lifting head 5. A base 52 is rotatably connected to the bottom end of the screw 51. A support rod 521 is connected between the outer edge of the base 52 and the lifting head 5 to prevent the base 52 from rotating relative to the lifting head 5. Three inner support rods 53 are rotatably hinged to the outer periphery of the base 52. The three inner support rods 53 are centrally symmetrically distributed. A threaded ring 54 is screwed onto the external thread of the screw 51, and a connecting rod 55 is hinged to each inner support rod 53 corresponding to the threaded ring 54. A bevel ring 56 is coaxially fixed to one end of the lifting head 5, and a bevel gear 57 is vertically meshed around the bevel ring 56. The lifting head 5 is also equipped with a motor 58 that drives the bevel gear 57 to rotate, so that when the screw 51 rotates, the screw ring 54 moves up and down, and then pulls the three inner support rods 53 to retract or open through the connecting rod 55. When it is in the retracted state, it is easy to insert into the inside of the base tube port, and when it is in the open state, it can press against the inner wall of the base tube from the inside.

[0028] Please see Figure 2 and Figure 4To improve the clamping stability of the base tube, an anti-slip pad 6 is connected to the outer wall of the top of the inner support rod 53. The anti-slip pad 6 is made of flexible silicone rubber to increase friction and prevent slippage. Furthermore, the surface of the anti-slip pad 6 has air holes 61, and a thin tube 7 connected to the air holes 61 is connected to the bottom of the anti-slip pad 6. The screw 51 has a hollow structure, and the thin tube 7 passes through the lower end of the screw 51 to the upper end. A rotary joint 8 is installed on the screw 51, and the other end of the thin tube 7 is connected to the rotary joint 8. The rotary joint 8 is also connected to the air pump 10 through the air pipe 9. The air pump 10 is fixed on the lifting head 5. When it is working, it creates a negative pressure state at the air hole 61, which facilitates the adsorption of the inner wall of the base tube and improves the firmness of the connection.

[0029] Please see Figure 1 , Figure 3 and Figure 5 To facilitate the loading and unloading of the optical guide drum base tube, the bottom end of the lifting frame 3 is rotatably connected to the base 2 via a turntable 11. A motor 312 that drives the turntable 11 to rotate is also installed below the base 2. By arranging infeed and outfeed conveyor belts on both sides of the device, when the turntable 11 drives the lifting frame 3 to rotate towards the infeed conveyor belt, the base tube can be taken off the infeed conveyor belt and then rotated back to the dip coating cylinder 1. The base tube is then placed into the dip coating cylinder 1 for dip coating. After dip coating is completed, the base tube is raised and can rotate towards the outfeed conveyor belt, and then the dip-coated base tube is placed on the outfeed conveyor belt.

[0030] Please see Figure 1 and Figure 5 To ensure the uniformity of the dipping solution, an overflow pipe 13 is connected to the upper side of the dipping cylinder 1. A storage cylinder 14 is located below the overflow pipe 13, and the bottom of the storage cylinder 14 is connected to the bottom of the dipping cylinder 1 via a water pump 15 and a pipe. This allows the dipping solution to circulate between the dipping cylinder 1 and the storage cylinder 14, ensuring its uniform flow and keeping the liquid level in the dipping cylinder 1 at the same height to ensure sufficient dipping. When it is necessary to add dipping solution, it can be added to the storage cylinder 14 without affecting the dipping operation in the dipping cylinder 1.
