The ink supply roller includes an inner rotating cylinder and an ink-absorbing layer, with both ends of the inner rotating cylinder rotatably engaged with the support, and the ink-absorbing layer disposed on the outer surface of the inner rotating cylinder; the ink supply tube is fixed to the support. This device solves the problem of existing equipment not being able to provide more stable and even ink supply. However, this device still has the problem of not being able to periodically clean the inner wall of the circulating ink supply device, reducing the practicality of the device. Utility Model Content
[0004] The purpose of this invention is to provide a printing circulating ink supply device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a printing circulating ink supply device, comprising:
[0006] The cabinet has four symmetrically arranged vertically adjustable linear motors connected to its inner wall. A connecting plate is welded to the moving part of every two linear motors. A scraper for ink cleaning is detachably connected to the outside of the connecting plate. The side wall of the scraper is slidably connected to the inner wall of the cabinet.
[0007] A support device is provided, with a material collection trough at the top and an inclined material collection trough at the bottom for collecting sediment. The material collection trough is also provided with a plug rod connected to the material collection trough on its periphery. The side wall of the plug rod is slidably connected to the plug hole, which is located at the bottom of the box body. The side wall of the box body is slidably connected to the material collection trough.
[0008] As a preferred embodiment, a drive motor that provides power is screwed to the top of the housing. The output shaft of the drive motor passes through the top of the housing and is connected to one end of a rotating shaft via a coupling. The other end of the rotating shaft is rotatably connected to the inner bottom wall of the housing.
[0009] As a preferred embodiment, a drive gear is fixed to the outside of the rotating shaft, and the drive gear is meshed with a driven gear. The drive gear and the driven gear are rotatably connected to the inner wall of the housing.
[0010] As a preferred embodiment, a propeller is welded to the outside of the shaft, and the sidewall of the propeller is not connected to the connecting plate.
[0011] As a preferred embodiment, a vacuum pump is provided on the top of the housing, and the working end of the vacuum pump is located inside the housing.
[0012] As a preferred embodiment, a water tank is provided on one side of the support device, and a heating device for heating is provided inside the water tank. A filling port is also provided on one side of the water tank.
[0013] As a preferred embodiment, a water pipe is connected to the top of the water tank, and the other end of the water pipe is connected to a hollow long plate.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0016] This printing circulating ink supply device has four linear motors installed inside the housing. A connecting plate is welded to the moving part of every two linear motors. A scraper is detachably connected to the side wall of the connecting plate and the moving part of the linear motor. The scraper slides against the inner wall of the housing under the action of the linear motor, thereby cleaning the inner wall of the housing. This prevents graphite from adhering to the inner wall and causing resource waste due to long-term use of the circulating ink supply device, and improves the practicality of the device.
[0017] This printing circulating ink supply device has an electric heating device inside the water tank. The electric heating device heats the water inside the tank, and the steam generated enters the tank through water pipes and a long plate. In conjunction with the installed drive motor, the drive gear and driven gear drive the rotating shaft to rotate, which in turn drives the connected propeller to rotate, thus completing the stirring of the ink inside the tank. This prevents the circulating ink supply device from being left stagnant for a long time, which would cause the ink to condense, and further improves the practicality of the device.
[0018] This device solves the problem that existing equipment cannot clean the ink adhering to the inner wall, thus avoiding waste of resources and improving the practicality of the device. Attached Figure Description

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0031] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0032] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0033] An embodiment of a printing circulating ink supply device, such as Figures 1 to 7 As shown,
[0034] include:
[0035] The housing 1 has four symmetrically arranged, vertically adjustable linear motors 11 connected to its inner wall. A connecting plate 12 is welded to the moving part of every two linear motors 11. A scraper 13 for ink cleaning is detachably connected to the outside of the connecting plate 12. The side wall of the scraper 13 is slidably connected to the inner wall of the housing 1. By controlling the movement of the moving part of the linear motor 11, the connecting plate 12 is moved, causing the scraper 13 to slide on the inner wall of the housing 1, thus cleaning the ink adhering to the inner wall of the housing 1. This avoids prolonged adhesion, which can cause the ink to clump together and lead to resource waste.
[0036] A drive motor 5, which provides power, is screwed to the top of the housing 1. The output shaft of the drive motor 5 passes through the top of the housing 1 and is connected to one end of the rotating shaft 8 via a coupling. The other end of the rotating shaft 8 is rotatably connected to the inner bottom wall of the housing 1. A propeller 9 is welded to the outside of the rotating shaft 8, and a drive gear 10 is fixed to the end of the rotating shaft 8. The drive gear 10 is meshed with a driven gear 7. Driven by the drive motor 5, the rotating shaft 8 inside the housing 1 is driven, thereby avoiding the ink circulation supply device. Even if it is left to stand for a long time, the ink can be kept uniform.
[0037] A water tank 3 is provided on one side of the housing 1. An electric heating device is installed inside the water tank 3. The electric heating device can heat the water inside the water tank 3, and the water vapor generated enters the hollow long plate 4 through the water pipe connected to the water tank 3. The two ends of the long plate 4 are connected to the water vapor and guide it into the housing 1. In order to prevent graphite from flowing back through the connecting pipe, a one-way valve is provided at the end of the connecting pipe. With the high temperature water vapor, the ink can be preheated and the ink can be prevented from solidifying due to long-term storage, which improves the practicality of the device.
[0038] A vacuum pump 6 is also installed on the top of the housing 1. The vacuum pump 6 is located on one side of the drive motor 5. The vacuum pump 6 can change the pressure inside the housing 1. Under the action of atmospheric pressure, the ink inside the housing 1 is concentrated, which further reduces the loss during ink circulation and supply and facilitates use. A feed pipe with a feed valve is provided on one side of the housing 1, and a discharge pipe is provided on the other side of the housing 1. The discharge pipe is connected to the pump body set inside the housing 1, so that the ink inside the housing 1 is transported out under the action of the pump body to complete the continuous ink supply to the printing press.
[0039] The rotation of propeller 9 will not come into contact with scraper 13 and connecting plate 12 set inside the housing 1, so that the internal structure of the device can operate stably. The operation of vacuum pump 6 causes the air pressure inside housing 1 to generate pressure from top to bottom along housing 1, thereby cleaning the ink inside housing 1.
[0040] A support device 2 provides support. The top of the support device 2 is provided with a material collection trough 22, and the bottom of the material collection trough 22 is provided with an inclined material trough for collecting sediment. The periphery of the material trough is also provided with a plug rod 21 connected to the material collection trough 22. The side wall of the plug rod 21 is slidably connected to the plug hole, which is located at the bottom of the box body 1. The side wall of the box body 1 is slidably connected to the material collection trough 22. The support device 2 can provide support for the box body 1 and prevent the internal structure of the box body 1 from moving during operation. In conjunction with the material trough set inside the material collection trough 22, a collection box 24 is also fixed at the bottom of the support device 2. A fixing plate 23 is welded to the top of the collection box 24. The fixing plate 23 is fixed to the bottom of the support device 2 by screws. The top of the collection box 24 is provided with a material outlet. Through the connection between the material outlet and the material trough, the sediment deposited inside the material collection trough 22 is collected, reducing impurities inside the ink and improving the ink supply quality.
[0041] The drive motor 5, vacuum pump 6, and linear motor 11 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The above structures operate in humid environments for a long time, so their surfaces are treated with corrosion resistance and they are regularly inspected and replaced. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0042] Working principle
[0043] When using this printing circulating ink supply device, the ink raw material is transported to the inside of the box 1 through the feed port. The electric heating device inside the water tank 3 is controlled to work, so that water vapor is generated inside the water tank 3. The vapor enters the inside of the box 1 through the connected pipe and the long plate 4. The output shaft of the drive motor 5 is rotated synchronously, which drives the connected rotating shaft 8 to rotate. This drives the drive gear 10, the driven gear 7 and the propeller 9 to rotate, thus completing the stirring of the ink inside the box 1.
[0044] Then, the movement of the moving part of the linear motor 11 is controlled periodically to drive the connected connecting plate 12 and scraper 13 to clean the inner wall of the box 1. Finally, the ink inside the box 1 is continuously supplied to the printing press through the pump.
