[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-3 The utility model provides a technical solution: a vacuum press roller internal cleaning device, comprising a vacuum press roller 1, a reciprocating slide assembly 2 is transversely arranged inside the vacuum press roller 1, the reciprocating slide assembly 2 comprises a linear motor 21 and a slide rail 22, and the slide rail 22 is located above the linear motor 21 and is arranged parallel to each other, and a mounting plate 23 is arranged between the linear motor 21 and the slide rail 22;
[0017] A plurality of rollers 24 are installed on the top of the mounting plate 23, and then the bottom of the mounting plate 23 is fixed on the mover 25 of the linear motor 21. At the same time, the rollers 24 on the top of the mounting plate 23 are embedded in the slide rail 22. When the linear motor is started, the mounting plate can be moved back and forth between the linear motor 21 and the slide rail 22. The structural design of the reciprocating sliding assembly is very stable during the back and forth sliding process. After the cleaning assembly 3 is installed on the mounting frame 26 on the surface of the mounting plate 23, the stability of the cleaning assembly 3 can be guaranteed even during the spraying and flushing process.
[0018] Then the cleaning component 3 is connected to the water tank 4 and the water circulation mechanism 5 respectively, and water can be supplied to the cleaning component through the water tank 4 or the water circulation mechanism 5;
[0019] The water tank 4 is arranged outside the vacuum pressing roller 1, and the water circulation mechanism 5 is arranged below the outside of the vacuum pressing roller 1, so that the waste water after flushing can enter the water circulation mechanism 5, and be used for cleaning components again after filtering.
[0020] In this embodiment, the cleaning assembly 3 includes a long spray tube 31, which is fixed on the mounting frame 26. The long spray tube 31 is provided with a plurality of high-pressure needle nozzles 32, and these high-pressure needle nozzles 32 are all arranged downward.
[0021] Then, the first water delivery pipe 33 provided on the body of the spray long pipe 31 is connected to the water tank 4, and the second water delivery pipe 34 is connected to the water circulation mechanism 5, and the water tank 4 or the water circulation mechanism 5 is used to supply water to the spray long pipe;
[0022] The first water pipe 33 and the second water pipe 34 are both flexible and stretchable tubes.
[0023] In this embodiment, the water circulation mechanism 5 includes a recovery frame 51. The sewage after flushing falls into the filter 52 in the recovery frame, and after being purified by the filter 52, it is again delivered to the cleaning component from the second water delivery pipe 34 for recycling.
[0024] Working principle: After the vacuum press roller has been working for 3-4 months, it should be cleaned regularly;
[0025] No need to stop the machine during cleaning to ensure that the roller surface of the vacuum press roller is still rotating;
[0026] At this time, you only need to open the water supply valve on the water tank or water circulation mechanism, and the cleaning component will start to spray high-pressure water. At the same time, start the linear motor to drive the cleaning component to reciprocate left and right. Use high-pressure water to spray from the inside of the vacuum pressing roller to the outside, and pass through the holes on the roller surface to break up and discharge the dirt accumulated in the holes. Since the roller surface is still rotating, the entire roller surface can be washed;
[0027] The wastewater generated during the flushing process will fall into the water circulation mechanism below and be circulated again to the cleaning components, greatly saving energy.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
