Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a dust removal and cleaning device for printing presses. Background Technology

[0002] A printing press is a machine for printing text and images. It generally consists of mechanisms such as plate mounting, inking, printing, feeding, and receiving platforms. The working principle is to first make a printing plate containing the text and images to be printed, mount it on the printing press, and then apply ink to the areas with text and images on the printing plate manually or by the printing press itself. The ink is then directly or indirectly transferred to paper or other printing substrates, thus reproducing printed materials identical to the printing plate. To ensure printing quality, the printheads and working platform of the printing press need to be cleaned regularly. However, existing cleaning methods are all manual, which not only increases the workload but also generates dust that is detrimental to people's health. Therefore, we propose a dust removal and cleaning device for printing presses. Utility Model Content

[0003] The purpose of this invention is to provide a dust removal and cleaning device for printing presses to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dust removal and cleaning device for a printing press, comprising a first bracket and a second bracket, a first motor fixedly connected to the bottom of the second bracket, and a third bracket fixedly connected to the output shaft of the first motor, a rotary joint fixedly connected to the left end of the front of the third bracket, and a rotating roller fixedly connected to the rear end of the rotary joint, a plurality of equally spaced dust suction grooves being provided on the left end of the inner surface of the rotating roller, a brush fixedly connected to the bottom of the rotating roller, a fourth bracket fixedly connected to the top of the rotating roller, and a sponge board provided on the outer side of the fourth bracket.

[0005] Preferably, a second motor is fixedly connected to the right end of the front of the third bracket, and the output shaft of the second motor is connected to the front end of the rotating roller via a single-sided toothed synchronous belt.

[0006] Preferably, the fourth bracket has screw holes at both the front and rear ends of its top, and a screw rod is threaded onto the inner surface of the screw hole. A reserved hole is also provided at the connection between the sponge plate and the screw rod.

[0007] Preferably, a mounting bracket is fixedly connected to the rear end of the top of the first bracket, and the inner surface of the mounting bracket is provided with mounting holes.

[0008] Preferably, a first hydraulic rod is fixedly connected to the front end of the first bracket, a second hydraulic rod is fixedly connected to the telescopic end of the first hydraulic rod, a filter box is fixedly connected to the telescopic end of the second hydraulic rod, the second bracket is fixedly connected to the left end of the back of the filter box, and the left side of the filter box is connected to the front end of the rotary joint through a pipe.

[0009] Preferably, the upper front end of the filter box is movably connected to a movable door via a hinge, and a handle is fixedly connected to the outer side of the movable door. A bracket is fixedly connected to the left end of the filter box cavity, and a polyvinyl chloride filter screen is clamped onto the inner surface of the bracket. A suction fan is fixedly connected to the right end of the bottom of the filter box cavity, and the output end of the suction fan is connected to the right side of the filter box via a pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention uses external bolts to fix the mounting bracket to the bottom of the work platform through the mounting holes. Controlling the extension and retraction of the second hydraulic rod drives the rotating roller to move up and down, while controlling the extension and retraction of the first hydraulic rod drives the rotating roller to move left and right. Controlling the rotation of the second motor allows the rotating roller to rotate via a single-sided toothed synchronous belt, enabling the sponge board to contact the top of the work platform or the bottom of the printhead. Simultaneously, the brush can be continuously rotated to facilitate cleaning of the work platform and printhead. During this process, the suction fan is turned on, drawing dust generated during cleaning into the rotating roller through the suction trough. With the cooperation of the rotary joint and pipe, the dust enters the filter box and is filtered by the PVC filter screen. Clean air is then discharged from the output end of the suction fan, ensuring a hygienic working environment. After cleaning, controlling the rotation of the first motor makes the rotating roller flush with the filter box, reducing the overall size and facilitating normal printing operations of the printer.

[0020] The working principle of this application is as follows: First, all electrical equipment is connected to the power supply and controller. Then, the mounting bracket 12 is fixed to the bottom of the work platform by external bolts passing through the mounting hole 3. By controlling the extension and retraction of the second hydraulic rod 11, the rotating roller 24 can be moved up and down. The extension and retraction of the first hydraulic rod 10 can drive the rotating roller 24 to move left and right. The rotation of the second motor 7 can be controlled to drive the rotating roller 24 through a single-sided toothed synchronous belt, allowing the sponge board 23 to contact the top of the work platform or the bottom of the printhead. At the same time, the brush 13 can be continuously rotated to facilitate cleaning of the work platform and printhead.
