Abstract
Description
Technical Field
[0001] This utility model relates to the field of inkjet printers, and in particular to an inkjet printer for plastic products. Background Technology
[0002] Plastic product coding refers to the technical process of marking and printing on the surface of plastic products using specialized equipment. It is widely used on production lines for various plastic products to mark key information such as production date, batch number, product specifications, or company logo. This technology not only helps achieve product traceability and quality management but also enhances brand image and market competitiveness.
[0003] Although inkjet printing technology is widely used in the plastics industry, existing inkjet printers suffer from poor positioning accuracy, easily leading to misaligned or blurred markings due to product position deviations, affecting readability and aesthetics. Furthermore, existing equipment often lacks flexible adjustment functions, making it difficult to quickly adapt to plastic products of different sizes or shapes, requiring frequent manual intervention from operators. This not only increases labor intensity but also reduces the overall efficiency of the production line. Therefore, a new inkjet printer for plastic products is proposed. Utility Model Content

[0006] Mounting frame: An adjustment component is installed on the lower side, two corresponding guide components are installed on the side of the adjustment component, a coding component is installed on the side of the mounting frame, and a positioning component is installed on the upper side of the coding component.
[0007] The conveying assembly includes conveyor rollers, a first mounting frame, a first motor, a conveyor belt, storage tanks, rubber strips, and a reflector. Two corresponding conveyor rollers are rotatably connected to the left and right ends inside the mounting frame. A conveyor belt is fitted onto the surface of the two conveyor rollers.

The conveying assembly is used to convey plastic products that need to be inkjet-printed.
[0008] Furthermore, the adjustment assembly includes a fixed frame, a moving bar, a bidirectional screw, a limiting rod, a second mounting bracket, and a second motor. The fixed frame is fixed to the lower side of the mounting bracket. Two corresponding moving bars are slidably connected inside the fixed frame. Threaded holes are opened on the left side of each moving bar, with opposite threads. A bidirectional screw is threaded into the two threaded holes, and is formed by welding two threaded rods with opposite threads. The bidirectional screw is rotatably connected inside the fixed frame. Limiting holes are opened on the right side of each moving bar, and a limiting rod is slidably connected inside the two limiting holes. The limiting rod is fixed inside the fixed frame.

The third mounting bracket is fixed to the right side of the support frame. The infrared rangefinder is mounted on the upper side of the third mounting bracket. The second hydraulic rod is mounted on the left side of the third mounting bracket. A mounting base is fixed to the telescopic arm of the second hydraulic rod, corresponding to the infrared rangefinder. An infrared sensor is mounted on the lower side of the mounting base, corresponding to a reflector. The infrared sensor is bidirectionally electrically connected to an external PLC controller. The input terminals of the infrared rangefinder are all electrically connected to the output terminals of the external PLC controller. At the output end, by setting a positioning component, the user can first confirm the spraying position of the plastic product inside the storage tank, and then activate the first hydraulic rod to adjust the front and rear position of the inkjet printer body according to the spraying position.
