Description

Technical Field

[0001] This utility model relates to the field of plastic bottle cap production technology, and in particular to a device for smoothing plastic bottle caps before inkjet printing. Background Technology

[0002] Plastic bottle caps are a common form of packaging for bottles, cans, and barrels, especially in the beverage, chemical, and pharmaceutical industries. To provide more information about the product and for traceability and authenticity verification, a QR code is usually printed on the top of the cap.

[0003] Bottle cap coding is done using a coding machine. However, before coding, dust may adhere to the surface of the bottle cap during the production process, and the surface of the bottle cap may have poor flatness, which can easily affect the adhesion and clarity of the coding. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a device for treating the flatness of plastic bottle caps before inkjet printing. This device can continuously treat the dust and flatness on the top of the bottle cap. It uses a plasma surface treatment head to emit plasma, which can significantly improve the energy level of the plastic surface, thereby enhancing the adhesion and clarity of the inkjet printing.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A device for smoothing plastic bottle caps before inkjet printing includes a processing tray, a material tray rotatably connected inside the processing tray, and multiple material inlets spaced apart on the circumferential sidewalls of the material tray. The front side of the processing tray is a loading position, the left side is a dust blowing position, the rear side is a processing position, and the right side is a unloading position. A dust blowing mechanism is installed at the dust blowing position to remove dust from the top surface of the bottle cap. The dust blowing mechanism includes a main air blowing pipe fixedly connected to the center of the processing tray. A sealing groove is provided at the bottom center of the material tray for the main air blowing pipe to extend into. Multiple radially arranged air blowing branch pipes are provided on the circumference of the material tray. A fan-shaped air outlet corresponding to the dust blowing position is opened on the left side of the main air blowing pipe. A plasma surface treatment head is installed above the processing position.

[0007] Preferably, the main air blowing pipe is arranged vertically, the branch air blowing pipes correspond one-to-one with the material inlets, and the outer end of the branch air blowing pipe is connected to the inner wall of the material inlet, while the other end of the branch air blowing pipe is connected to the sealing groove.

[0008] Preferably, a sealing ring is circumferentially installed on the top of the air blowing manifold, and the sealing ring has a corresponding fan-shaped air outlet on the side corresponding to the dust blowing position.

[0009] Preferably, an arc-shaped dust discharge channel is fixedly installed on one side of the processing disk corresponding to the dust blowing position, and the arc-shaped dust discharge channel is connected to the left side of the processing disk.

[0010] Preferably, a bracket is fixedly installed on the rear side of the processing tray, the plasma surface treatment head is fixedly installed at the bottom of the bracket, and a motor is also installed at the bottom of the bracket, with the output end of the motor fixedly connected to the top of the tray.

[0011] Preferably, the bottom of the processing disc corresponding to the material feeding position is provided with a feeding port, and a feeding belt is installed below the feeding port.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By installing a processing tray, a material tray, a feeding position, a dust blowing position, a processing position, and a discharging position, plastic bottle caps are fed into the processing tray through the feeding channel. The motor is started to drive the material tray to rotate, and the plastic bottle caps are fed one by one into the rotating material inlet. Under the limit of the material inlet and the edge of the processing tray, the plastic bottle caps are continuously positioned and conveyed, passing through the feeding position, dust blowing position, processing position, and discharging position in sequence, completing the automated processing of the bottle cap surface flatness, which is highly efficient.

[0014] 2. By installing a dust blowing position, a main air blowing pipe, branch air blowing pipes, a sealing groove, and a fan-shaped air outlet, the main air blowing pipe is connected to an external air pump to continuously blow gas into the interior. Multiple plastic bottle caps pass through the dust blowing position. Since the fan-shaped air outlet corresponds to the dust blowing position, the gas is blown into the multiple branch air blowing pipes passing through the dust blowing position through the fan-shaped opening. The gas blows over the top surface of the bottle caps in the inlet, blowing away the dust on their tops and discharging it into the arc-shaped dust discharge channel on one side. The dust blowing process is maintained for a period of time, resulting in good dust removal effect.

[0015] 3. By installing a processing position and a plasma surface treatment head, each plastic bottle cap is rotated through the plasma surface treatment head. The plasma surface treatment head emits plasma onto the top of the bottle cap, which can significantly increase the energy level of the plastic surface, thereby enhancing the adhesion and clarity of the inkjet printing.
