Description

Printing roller cleaning device {Printing roller cleaning device}

The present invention relates to a printing roller cleaning device, and more particularly, to a printing roller cleaning device including a driving device in an immersion cleaner having a driving mechanism driven by a directional flow of a circulating cleaning solution in a storage tank.

Machine parts collect dust, wear debris, spent grease, and other debris during normal operation. In the printing industry, rollers are used to clean ink or other chemicals from storage tanks or to spray these chemicals across a substrate in a defined pattern found on other rollers. The printing roller gradually collects dust, disturbs the particulates, and even dries the ink. Five different techniques are known in the industry: manual part cleaning, automatic part cleaning, spray immersion cleaning, wet part cleaning and abrasive blast cleaning using a variety of different media. Printing roller cleaning can easily be done manually using a sponge, brush, or towel, or using an automated device. Some units operate onsite without requiring removal of the printing rollers, while others operate offsite, once the printing rollers are removed and transferred to a printing roller cleaner. This invention relates to a roller cleaning apparatus for printing using immersion cleaning with or without spray-under-immersion cleaning and immersion-under-immersion cleaning. A parts washer is a device for cleaning machines and machine parts or parts individually or in groups, including, but not limited to, cleaning of printing rollers. is a subgroup of The core technology associated with immersion cleaning is no different from the technology associated with immersion cleaning of automotive parts in repair shops. Some parts cleaners use liquid cleaning solutions to tackle and remove grease, carbon, resin, tar, ink, and other debris. These parts cleaners use water, soap, and/or commonly or exclusively synthetic detergents. More advanced parts cleaners use hydrocarbon solvents or other solvents to degrease and clean parts. The cleaning solution may be abrasive, solvent based, or corrosive as the case may be, requiring confinement, filtration and disposal. Although a water-based solution is used in the immersion process, the cleaning residue may be abrasive, solvent-based, or corrosive, requiring confinement, filtration, and disposal. The printing roller is also a generally heavy cylindrical component of a more or less delicate printing surface with two supporting ends of a cylindrical shape. Different lengths and radii of rollers must be used in tandem in the printing industry, usually on a single printing press. Printing roller cleaners must accommodate different sized rollers with different lengths, radii, and weights. Cleaning requires relative movement of the cleaning solution with the surface of the printing roller to aid in the separation of contaminant particles in the cleaning solution. The most effective way to move the roller through the cleaning solution is to rotate the roller at the maximum speed of the cleaning solution on the surface. Other relative movements are difficult because of the inertia of the rollers in the fluid. To rotate the printing roller, a drive means is required, and in the prior art, a mechanically driven means is used, which is connected to a motor via a chain or belt. Unlike cleaning solutions that can be easily regenerated, the drive means and motor must be cleaned periodically. What is needed is a drive means that does not require any periodic maintenance or cleaning. Another common problem with the prior art is the inability to clean both the entire print surface and the tiers, so the prior art systematically holds the print rollers on wheels or even tiers positioned along the print surface. In either case, the line or surface cannot be effectively cleaned. What is required is a support device, which reduces cleaning interference by allowing the cleaning solution to reach the entire outer surface of the print roller during the cleaning operation. The side wall of the storage tank is equipped with a low mechanism. A roller chain drive mechanism is attached to the support roller to cleanly rotate the print roller. The obvious flaws of this device are its inability to accommodate the narrow printing rollers, the need for the use of a drive mechanism that is partially submerged in the cleaning solution, which then draws the cleaning solution out of the storage tank, essentially reducing the performance of the non-immersion motor. Fall down. The rail unit can be adjusted to accommodate the narrow print roller, the driving mechanism is the outside of the reservoir tank and the support of the print roller is held outside the cleaning solution. A significant disadvantage of this device is the inability to clean one support end of the critical portion of the print roller. The device also requires a top cover to prevent splashing or evaporation of the fumes during the cleaning process. A drive mechanism of a single belt structure is presented and connected to a motor located outside the storage tank. Significant disadvantages of this apparatus are the need for sets of wheels and the inability to clean the print roller without reclassifying it sufficiently to support the print surface across the wheels near the end of the print roller. What is needed is an immersion cleaner for print rollers capable of cleaning the entire print roller without damaging the print surface of the print roller. Also needed is a printing roller cleaning device capable of rotating the print without requiring a roller chain or strap at the interface between the cleaning solution and the drying section of the printing cylinder washer.

A portion of the printing cylinder washer that further contains a transducer in fluid communication with the cleaning solution for sending ultrasonic waves to the cleaning solution to clean the printing cylinder is addressed.

Solved by further containing the door at the top of the storage tank to provide access to the inside of the storage tank

SUMMARY OF THE INVENTION The present invention provides a printing roller cleaner having a movable or portable drive, or a series of portable drives of different lengths to accommodate different dimensions of the printing roller.

The present invention is not limited to the specific description of the device, and other variations and applications are contemplated. Other changes may be made to the device herein without departing from the true spirit of the scope of the present invention. Therefore, the gist of the above description should be interpreted as illustrative and not limiting. For those skilled in the art, the support table can be moved by mechanical, fluid, pneumatic, and electromechanical means located behind the support table operated by a command bay that raises or lowers the support table. Including, but not limited to, sliding rails or elevator devices. A fixed support table with telescopic or adjustable legs may be used, either directly on the bottom of the storage tank, or positioned on an edge formed on the side wall of the storage tank forming the collecting pan. The support table is shown as a grate through which the cleaning solution flows into the storage tank so that crumbs and other particles fall into the cleaning solution during cleaning or onto the lower portion of the washer. In a preferred embodiment, the debris can be collected in a bend formed in the bottom located next to the drain with the control valve. The debris collection device is shown to operate on the principle that any debris or particles having a greater density than the cleaning solution fall into the cleaning solution in the lower portion of the storage tank due to their own weight during the cleaning cycle. Instead, particles or debris with a lower density than the cleaning solution are raised to the surface where they can be filtered by the external filter before the cleaning solution is recycled into the storage tank. The scrubber also includes a pump having an inlet in fluid contact with the cleaning solution, a first outlet connected to the spray wand, and a second outlet connected to the directional nozzle. The storage tank also includes a top door with a flat hinged door with an automated opening mechanism. The upper door is equipped with a lift bar attached to a thermal breaker. The mechanism of the lifting column allows the lift bar to slide the slide to pull the door on its hinges. Although one mechanical door opening device is described, it is capable of opening doors, including but not limited to retractable doors made of pieces, drop-down doors slidably connected to sidewalls in rails, magnetic lift devices, and the like. Any mechanical or electromechanical device available may be used. A thermal breaker is a device that adjusts to release the lift bar from its contact point on the top door if a certain temperature is reached over a certain period of time. The thermal breaker is geared to release the door when the cleaning solution in the storage tank or surface chemicals on the cleaning solution burn. For example, the command bay contains timers, temperature sensors, active and passive buttons, and programming devices to adjust the different wash parameters in the reservoir. In some embodiments a heater may be used to increase the temperature of the cleaning solution to increase the degree of dilution of the cleaning solution. The command bay is preferably a controller, usually comprising a pump control to increase or decrease the speed of the drive cylinder via the drive wheels to adjust the flow of cleaning solution out of the directional nozzle or to adjust the flow of spray in the storage tank. used The command bay as shown includes a flow valve and an air valve associated with a pressure gauge to steer an ultrasonic vibrating head that induces and maintains a vibrating wave within the cleaning solution that helps remove contaminant particles adhering to the surface of the printing roller. You may. In another embodiment, the vibrator is a transducer. The command bay also includes a lift lever, shown as a joystick with a ball and control buttons to control the vertical movement of the support table.

Although described as using an external power source, it may be any means of powering the different elements, including the use of an alternator or a battery may be used. The scrubber of the preferred embodiment includes a U-shaped tube attached to the bottom of the storage tank for lifting the scrubber using a fork placed on a manual forklift or an automatic forklift. Means for positioning and transport are described, but devices for holding, storing, positioning, or transporting the scrubber may be used. Structural stiffeners, such as L-shaped bars, are present at the outer edges of the side walls to reinforce the storage tank. In a preferred embodiment, the upper edge of the storage tank has a frame, which is made to hold and protect the upper edge of the side wall, but also supports the upper door and seals to prevent potential vapors generated by the cleaning solution in the storage tank. plays the role of Mechanical structural reinforcements disposed inside or outside the storage tank may be used to maintain structural integrity when the scrubber is filled or moved. A filtration cartridge with a manual valve on top can be used to control the flow of cleaning solution from the pump to the secondary outlet and finally to the directional nozzle. In one embodiment, the pump regulates a steady flow of cleaning solution directed fully to the spray wand when the manual valve is closed and no drive force is required on the drive wheel. When the manual valve is open, the flow of cleaning solution to the spray wand is reduced based on different elements of the device. One skilled in the art may be able to adjust the flow through the primary and secondary outlets, including, but not limited to, manual valves, regulating diaphragms, automatic valves, multiple in-line pumps, piping of different dimensions or high pressure hoses in constriction zones. You'll know how many ways there are. This configuration device may further include a frame made of metal tubes and plates. In one embodiment, the different components of the frame are assembled using welds and screws. The frame is also open below the printing cylinder to enhance circulation of the cleaning solution in the reservoir. A frame having an end support plate slidably connected to the bottom frame may also be used to adjust the distance between the two printing cylinder supports mounted on the vertical support. The printing cylinder cleaner also includes a driving device disposed on a support table having a driving wheel, a transmission, a driving cylinder, and a printing cylinder support. In another embodiment, the printing cylinder support presses the printing cylinder against the driving cylinder by sliding down according to the sliding support at an equivalent position closest to the driving cylinder. In that embodiment, the drive wheel is a paddle wheel that converts flow motion in the cleaning solution in the holding tank into a rotational drive force at the center of the drive wheel. The drive system further includes as part of the overall transmission a first strap and a second strap connected to the radial wheel and on the main shaft of the transmission. In one embodiment, the drive cylinder includes a large wheel that works with the transmission to generate the rotational speed of the drive cylinder required by the drive. The transmission may be used to slow down the rotational speed of the drive cylinder if the drive flow is too fast, or accelerate the rotation of the drive cylinder if the drive flow of cleaning solution is slow. Even when a second flow is directed from the inlet to the directional nozzle so that the cleaning solution is discharged from the directional nozzle as a stream, the cleaning solution contacts the drive wheel and the drive wheel rotates and the transmission provides rotational motion from the drive wheel to the drive cylinder. do. A print cylinder support places the print cylinder close to the drive cylinder, and a pump circulates cleaning solution from the storage tank from the inlet to the spray rod such that a flow of cleaning solution is formed when the cleaning solution is expelled from the spray rod. A series of cylinder supports are presented and one support is angular to allow the printing roller to be placed on the support with one support pressed against the drive cylinder. In one embodiment, a series of small friction tabs disposed on the drive cylinder are shown to prevent differential rotation between the drive and printing cylinders. In another embodiment, the drive cylinder contains brushing media or friction base media that drives the printing roller. A biasing means may be used to pull the print roller against the drive cylinder after placing the print roller on the cylinder support. In another embodiment, the support table is a grate connected to an elevator device for raising or lowering a support table disposed on the grate and a driving device. In another embodiment, the support table is an agitator platform designed to agitate the print roller and vibrate it under submersion at the same time. The method includes successive steps of placing a drive device on a support table of a printing cylinder cleaner having a cleaning solution and a storage tank constituting a space in which the support table is disposed. The printing cylinder to be cleaned is placed on the next printing cylinder support. The directional nozzle is then aligned with the driving wheel and the printing cylinder is placed in the flow of the spray wand. The pump then directs the cleaning solution through the spray wand via the first outlet to clear the printing cylinder and drives the drive wheel to rotate the printing cylinder to direct the cleaning solution through the directional nozzle via the second outlet. Initiate. In one alternative embodiment, the method further comprises moving the support table as an agitation platform, and in another embodiment, the method applies ultrasound to the cleaning solution to remove contaminating particles from the surface of the printing cylinder.
