Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to an automatic feeding device with a dust removal function for a printing machine. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. Its principle is to first make the text or image to be printed into a printing plate, install it on the printing press, and then apply ink to the place where the text and image are on the printing plate manually or by the printing press, and then directly or indirectly transfer it to paper or other printing materials. When the existing sheet automatic printing press is working, dust will stick to the sheet, which will affect the printing effect, so a dust removal mechanism is needed to remove the dust on the sheet.

[0003] For example, Chinese patent announcement No. CN208881349U discloses an automatic sheet printing machine with a dust removal function. When in use, the sheet passes between two dust removal rollers, the dust removal roller removes dust on the sheet, and the dust suction roller absorbs dust on the dust removal roller. After a long period of use, the first handle can be rotated to drive the first threaded rod to rotate, thereby moving the first movable plate, and driving the dust removal roller up and down through the first connecting shaft, thereby adjusting the positions of the two dust removal rollers, making the two dust removal rollers further fit together, thereby improving the dust removal effect, and then rotating the second handle to drive the second threaded rod to rotate, the second movable plate moves up and down, and driving the dust suction roller up and down through the second connecting shaft. The dust suction roller is made to fit the dust removal roller through adjustment, thereby improving the dust suction effect.

[0004] However, the automatic sheet printing machine with dust removal function in the above application requires manual adjustment of the height of the dust removal roller, which poses certain safety hazards and is inconvenient to use. Moreover, when faced with rolls of different volume sizes, it cannot be adjusted specifically according to the size of the roll. Therefore, it has certain limitations.

[0005] For this reason, we urgently need to provide an automatic feeding device with dust removal function for a printing press. Summary of the invention

[0006] The purpose of the utility model is to provide an automatic feeding device with a dust removal function for a printing machine, so as to solve the problem that the automatic sheet printing machine with a dust removal function proposed in the above-mentioned background technology needs to manually adjust the height of the dust removal roller, which has certain safety hazards and is inconvenient to use. Moreover, when faced with rolls of different volume sizes, it is impossible to make targeted adjustments according to the size of the roll.

[0007] To achieve the above object, the present utility model provides the following technical solution: An automatic feeding device with a dust removal function for a printing machine, comprising a feeding rack and a dust removal rack. The dust removal rack is installed behind the feeding rack. A feeding device is arranged inside the feeding rack, and a dust removal device is arranged at the bottom of the dust removal rack.

[0008] The feeding device includes an adjusting unit and a feeding unit.

[0009] The adjusting unit includes an adjusting motor, a transmission member, and a connecting seat. The adjusting motor is installed at the inner top of the feeding rack. The transmission member is connected to the output end of the adjusting motor, and the connecting seat is fixedly connected to one side of the transmission member.

[0010] Further improvement lies in that a limiting sliding groove is formed inside the feeding rack. The transmission member is rotatably connected inside the limiting sliding groove, and the connecting seat is slidably connected inside the limiting sliding groove. During feeding, the adjusting motor is started to drive the lead screw in the transmission member to rotate inside the bearing in the limiting sliding groove, thereby driving the threaded sliding sleeve on the lead screw and the connecting seat on one side thereof to slide downward along the inner wall of the limiting sliding groove, thus driving the feeding unit to move downward.

[0011] Further improvement lies in that the feeding unit includes a rotating motor, a rotating shaft, an electric telescopic rod, a contact plate, and a feeding rod. The rotating motor is installed inside the connecting seat. The rotating shaft is connected to the output end of the rotating motor and extends outside the connecting seat. The electric telescopic rod is fixedly connected to the outer end of the rotating shaft. The contact plate is fixedly connected to the outer end of the electric telescopic rod. The feeding rod is fixedly connected to the center of the outer surface of the contact plate.

[0012] Further improvement lies in that there are two feeding racks in total. A roll material is clamped between the two feeding racks. Subsequently, the two electric telescopic rods are synchronously driven to move outward, so that the two feeding rods move relatively and are inserted into the feeding holes of the roll material until the contact plates abut against both sides of the roll material for fixation. Subsequently, the rotating motor is started to drive the rotating shaft to rotate, thereby driving the electric telescopic rod and the clamped roll material to rotate for feeding, so as to adapt to roll materials of different volumes and sizes, improving the applicable range of the device. A controller is installed on the front of the right feeding rack. The feeding device and the dust removal device are respectively electrically connected to the controller, and the operation of the device is controlled by the controller.

[0013] A further improvement is that the dust removal device includes a lifting cylinder, a mounting frame, a rotating bearing, and a dust removal component. The lifting cylinder is installed at the center of the lower surface of the dust removal frame. The mounting frame is fixedly connected to the bottom of the lifting cylinder. Two rotating bearings are respectively installed on the inner walls of both sides of the mounting frame. The dust removal component is rotatably connected to the inside of the rotating bearing. When facing coiled materials of different thicknesses, the lifting cylinder is started to drive the mounting frame to move downward, thereby driving the dust removal component to move downward, so that the dust removal component fits on the surface of the coiled material to remove dust from it.

[0014] A further improvement is that the dust removal component includes a rotating shaft, a dust removal roller, and an electrostatic dust removal film. The left and right ends of the rotating shaft are respectively rotatably connected to the inside of the rotating bearing. The dust removal roller is installed on the outside of the rotating shaft. The electrostatic dust removal film is adhered to the outer surface of the dust removal roller. When the coiled material is loaded, the frictional force generated between the coiled material and the dust removal roller drives the rotating shaft inside the dust removal roller to rotate inside the rotating bearing, thereby realizing the dust removal during the loading of the coiled material. And an electrostatic dust removal film is adhered to the outer surface of the dust removal roller. When too much dust adheres to the electrostatic dust removal film, just remove the electrostatic dust removal film and replace it with a new one, which is more convenient to use.

[0015] A further improvement is that a set of dust removal components are also installed at the bottom of the dust removal frame. The two sets of dust removal components cooperate with each other to remove the dust adhered to both surfaces of the coiled material.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. For the automatic loading device with a dust removal function for this printing machine, when loading, the adjustment motor is started to drive the transmission part to rotate, so that the connecting seat slides downward along the inner wall of the limit chute, thereby driving the loading unit to move downward. After the loading is completed and it rises again, the loading can be quickly completed, improving the processing efficiency.

[0018] 2. For the automatic loading device with a dust removal function for this printing machine, the two electric telescopic rods are synchronously driven to move outward, so that the two loading rods move relatively and are inserted into the loading holes of the coiled material until the abutting plate abuts against both sides of the coiled material for fixation. Then the rotation motor is started to drive the rotating shaft to rotate, thereby driving the electric telescopic rods and the coiled material clamped by them to rotate for loading, so as to adapt to coiled materials of different volumes and sizes, improving the application range of the device.

[0019] 3. For the automatic loading device with a dust removal function for this printing machine, when facing coiled materials of different thicknesses, the lifting cylinder is started to drive the mounting frame to move downward, thereby driving the dust removal component to move downward, so that the dust removal component fits on the surface of the coiled material to remove dust from it.
