Description

Technical Field

[0001] The utility model relates to the technical field of cup printing equipment, in particular to a large printing roller with a dust removal function. Background Art

[0002] The surface treatment of the cup before printing will generate dust, which will be adsorbed on the surface of the rubber blanket of the printing roller. During printing, it is easy to cause defects such as scratches and abrasions on the product. In order to solve the above problems, the current conventional practice is to manually wipe the dust adsorbed on the surface during the production process, but the production efficiency is affected because the machine needs to be stopped before manual wiping, and manual wiping shortens the service life of the rubber blanket. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the utility model is to provide a large printing cylinder with a dust removal function to solve the problems caused by the above background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is a large printing roller with dust removal function, comprising:

[0005] The roller assembly comprises a roller and a rubber blanket. The axial direction of the roller extends along a first direction. The rubber blanket surrounds and is attached to the roller along a circumferential direction, and the circumferential direction surrounds the first direction.

[0006] The dust removal assembly includes a wind knife assembly. The wind knife assembly includes a wind knife and a rotating shaft. The wind knife is arranged radially away from the drum and arranged on one side of the drum along a second direction, the radial direction is perpendicular to the first direction, and the second direction is perpendicular to the first direction. The wind knife can rotate around the rotating shaft so that the blowing direction of the wind knife faces the rubber cloth.

[0007] The large printing roller with dust removal function provided by the utility model is arranged on the side of the cup dividing module, and is used for printing on the surface of the cup. The wind knife assembly in the blowing mechanism blows air in the direction where the rubber blanket is located, so as to blow up the dust adsorbed by the rubber blanket, and ensure the cleanliness of the rubber surface. The wind knife in the wind knife assembly can adjust the blowing angle through the rotating shaft, so that when the rubber blanket is replaced with different sizes, the blowing direction of the wind knife is adjusted to adapt to the change of the width of the rubber blanket, so that the wind knife always blows air in the direction where the rubber blanket is located, which can reduce the frequency of stopping for cleaning and increase the service life of the rubber blanket.

[0008] In some embodiments, the drum assembly further comprises a first side plate, a second side plate and a central axis. The first side plate and the second side plate both extend along the second direction and are respectively arranged on both sides of the drum along the first direction. The rotating shaft extends along the first direction and passes through the axis of the drum. Both ends of the rotating shaft are respectively connected to the first side plate and the second side plate.

[0009] By adopting the above technical solution, the roller is fixed by the first side plate and the second side plate, and rotates around the central axis, and the rubber cloth on the surface of the roller is used for rolling printing on the cup.

[0010] In some embodiments, the wind knife assembly further includes a base, which is disposed below the wind knife, with one end connected to the wind knife and the other end connected to the first side plate.

[0011] In some embodiments, the air knife assembly further comprises an air pipe joint, one end of which is connected to the air knife, and the other end of which is connected to an external air inlet pipeline, for adjusting the air output of the air knife.

[0012] By adopting the above technical solution, the air pipe joint is arranged on the side of the wind knife away from the rubber cloth, so that the volume and speed of the air blown by the wind knife can be adjusted.

[0013] In some embodiments, the dust removal assembly further includes an exhaust hood. The exhaust hood is disposed on the other side of the drum along the second direction and is fixed to the second side plate. The exhaust hood includes an air outlet for communicating with an external air suction pipeline to absorb and transfer dust blown up by the wind knife.

[0014] With the above technical solution, the dust removal component absorbs the dust blown by the wind knife through the exhaust hood to prevent dust from polluting the working environment. The sucked dust flows out through the air outlet for centralized collection. The wind knife can adjust the angle to aim at the rubber blanket to blow up the dust on the rubber blanket, and the exhaust hood on the other side extracts the air mixed with dust. The two work synchronously to form a cycle to achieve the effect of real-time cleaning of the rubber blanket.

[0015] In some embodiments, the exhaust hood is disposed corresponding to the position of the wind knife, and the inlet end of the exhaust hood is disposed along the first direction facing the wind knife.

[0016] By adopting the above technical solution, the exhaust hood and the wind knife are set correspondingly, which can quickly suck in the dust and avoid the long-distance absorption path that causes the dust to spread in the device.

[0017] In some embodiments, the exhaust hood includes a mesh cover surface, and the mesh cover surface is arranged at the inlet end of the exhaust hood.

[0018] By adopting the above technical solution, the suction surface of the exhaust hood is set to a grid shape, which can ensure that the airflow can be evenly distributed and mixed before entering the exhaust hood. If the inlet end of the exhaust hood is open, excessive adsorption force may cause a certain degree of positional displacement of the rubber cloth, affecting the printing effect of the cup.
