Description

Technical Field

[0001] This utility model relates to the field of rubber blanket cleaning technology, specifically to an adsorption cleaning device for cleaning rubber blankets to prevent pumice powder residue. Background Technology

[0002] A printing blanket is a composite material product consisting of a rubber coating and a substrate (such as fabric). In indirect offset printing, it is used to transfer ink from the printing plate to the substrate. During the printing process of a flatbed printing press, lint, impurities, etc., on the substrate inevitably stick to the printing blanket. To ensure printing quality, the printing press's printing blanket cleaning device needs to clean the blanket. However, existing cleaning devices generally involve contacting a cleaning cloth with the printing blanket. The rotation of the transfer cylinder causes the printing blanket to come into contact with the cleaning cloth, thereby cleaning the blanket. Although this achieves the effect of cleaning the blanket, the contact surface between the cleaning cloth and the printing blanket does not change. The contaminated cleaning cloth will then smear the ink powder back onto the printing blanket, resulting in incomplete cleaning. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a reasonably designed and easy-to-use adsorption and cleaning device for cleaning rubber blankets to prevent pumice powder residue, which can effectively solve the defects of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a cleaning tank, support plates, and a collection tank; support plates are provided on both sides of the bottom wall of the cleaning tank; material inlets are provided on the upper sides of both side walls of the cleaning tank; and a collection tank is provided on the lower side of the cleaning tank; it also includes:

[0005] The contact rollers consist of two rollers, which are symmetrically connected to the inside of the cleaning tank via shafts. Three guide rollers are screwed onto the center side of the inside of the cleaning tank via bearings. One guide roller is located on the upper side of the center inside the cleaning tank, and the other two guide rollers are symmetrically arranged on the lower side of the inside of the cleaning tank.

[0006] The installation rollers are four in number and are screwed into the cleaning tank by bearings. A cleaning cloth is covered on the outside of the installation rollers. A rotating motor is fixed to one end of one of the installation rollers and the rotating motor is fixed to the outer wall of the cleaning tank.

[0007] The cleaning mechanism is located inside the cleaning tank and is designed to work in conjunction with the cleaning cloth.

[0008] The guide bucket is embedded and fixed in the bottom wall of the cleaning tank, and the lower end of the guide bucket passes through the lower side wall of the cleaning tank and is inserted into the collection box.

[0009] The diversion pipe is embedded and fixed on the inner wall of one side of the cleaning tank. One end of the diversion pipe is connected to the external cleaning liquid through an external pump. Several nozzles are equidistantly inserted through the diversion pipe on the side of the outer ring wall of the cleaning tank that is inside the cleaning tank.

[0010] The above technical solution involves inserting the rubber blanket into the cleaning tank through the feed port on one side, passing it through the contact roller on one side, and then sequentially passing it through the lower side of the adjacent lower guide roller, the upper side of the upper guide roller, the lower side of the other lower guide roller, and the upper side of the other contact roller before exiting through the feed port on the other side. At this point, one side of the cleaning cloth is in contact with the rubber blanket. Then, the external pump is activated, which pumps the cleaning solution into the distribution pipe and sprays it onto the rubber blanket through the nozzle for initial rinsing. When the rubber blanket comes into contact with the cleaning cloth, it is absorbed and cleaned by the cleaning cloth. The rotating motor is then activated, which drives the connected mounting roller to rotate. The cooperation of the four mounting rollers causes the cleaning cloth to rotate, and at the same time, the cleaning mechanism is activated to clean the cleaning cloth, thereby preventing the contaminated cleaning cloth from smearing stone powder back onto the rubber blanket and improving the cleaning effect.

[0011] As a further improvement of this utility model, a cleaning roller brush is screwed onto the lower side of the inside of the cleaning tank via a bearing. The cleaning roller brush is located below the guide roller adjacent to the side of the diversion pipe.

[0012] With the above technical solution, after rinsing the rubber blanket with a nozzle, the rubber blanket can be brushed with a cleaning roller brush, which reduces the impurities adhering to the rubber blanket.

[0013] As a further improvement of this utility model, a filter screen is provided in the middle of the inside of the collection box, and a connecting pipe is provided on the lower side of the filter screen. The other end of the connecting pipe is connected to the inlet of the pump connected to the diversion pipe through a three-way connector.

[0014] With the above technical solution, after cleaning, the cleaning fluid flows into the collection tank through the guide bucket, and after being filtered through the filter screen, it flows to the lower side of the collection tank. After the cleaning fluid has been collected for a period of time, the filtered cleaning fluid is pumped into the distribution pipe by the pump connected to the distribution pipe, thereby achieving the effect of reuse.

[0015] As a further improvement of this utility model, the cleaning mechanism includes:

[0016] A fixing plate is provided on the middle side inside the cleaning box, and the front and rear sides of the fixing plate are fixed to the front and rear inner walls of the cleaning box.

One of the rotating tubes is connected to the rotating rod via a synchronous wheel transmission assembly. Each rotating tube has a cleaning brush fixed to its outer end. The cleaning brushes are meshed with each other and abut against the outer wall of the cleaning cloth.

[0019] The conveying pipe consists of several pipes, each corresponding to the other and inserted into the rotating pipe. One end of the conveying pipe is movably inserted into the cleaning brush, and the other end of the conveying pipe is connected to an external pumping pump via a connecting pipe.

[0020] The above technical solution starts the cleaning motor at the same time as the external pumping pump is started. The pumping pump draws water and sprays it onto the cleaning cloth. The cleaning motor drives the rotating rod to rotate. The rotating rod drives the rotating tube connected to it to rotate through the synchronous wheel transmission assembly. The rotating tube drives the cleaning brush on it to rotate. The cleaning brush drives several meshing cleaning brushes to rotate, and the cleaning cloth is brushed by the cleaning brushes.

[0021] As a further improvement of this utility model, several sliding blocks are equidistantly arranged from front to back inside the top wall of the cleaning box. A push spring is fixed on one side wall of the sliding block, and the other end of the push spring is fixed on the inner wall of the sliding groove of the cleaning box. A push plate is arranged on the upper side inside the cleaning box. The upper side of the push plate is fixedly connected to several sliding blocks, and the inclined surface of the push plate is set to abut against the rubber cloth.

[0022] With the above technical solution, when cleaning the rubber blanket, the spring drives the sliding block to move, the sliding block drives the push plate to move, and the push plate pushes the rubber blanket, thereby ensuring that the rubber blanket and the cleaning cloth come into contact.

[0023] As a further improvement of this utility model, movable wheels are equidistantly arranged on the inclined surface of the push plate, and the movable wheels are arranged to abut against the rubber sheet after passing through the inclined surface of the push plate.

[0024] The above technical solution facilitates the movement of the rubber blanket between the cleaning cloth and the push plate.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: The adsorption and cleaning device for cleaning rubber blankets to prevent pumice powder residue can simultaneously clean the cleaning cloth while cleaning the rubber blanket, thereby preventing the contaminated cleaning cloth from wiping the pumice powder back onto the rubber blanket, thus improving the cleaning effect. This utility model has the advantages of reasonable design and low manufacturing cost. Attached Figure Description
