Description

Technical Field

[0001] This application relates to the field of inkjet printing apparatus technology, and in particular to an inkjet printing apparatus for plastic bags. Background Technology

[0002] Plastic bags are an essential item in people's daily lives, often used to pack other items. They are widely used because of their low price, light weight, large capacity, and ease of storage. Currently, in the plastic bag production process, it is often necessary to print and code the plastic bags to ensure that the plastic bags have the trademarks, barcodes, etc. required by the manufacturer.

[0003] In the existing technology, it is inconvenient to dry the printed pattern or barcode during use, and it is also inconvenient to position the plastic bag, which leads to a reduction in printing quality. To address these issues, we propose a plastic bag printing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing inkjet printing devices, such as the inconvenience of drying printed patterns or barcodes and the difficulty of positioning plastic bags during use, which leads to a reduction in printing quality. Therefore, this invention proposes a plastic bag inkjet printing device.

[0005] The plastic bag printing device provided in this application adopts the following technical solution:

[0006] A plastic bag printing device, comprising:

[0007] The workbench and the vertical plate are fixedly installed on the top of the workbench. A horizontal plate is fixedly installed on the outside of the vertical plate, and a printer is fixedly installed on the top of the horizontal plate.

[0008] The drying oven is fixedly installed on the top of the horizontal plate. The bottom inner wall of the drying oven has an air outlet, and the top of the drying oven has an air inlet. A dustproof net is installed inside the air inlet. The drying oven is equipped with a drying mechanism for drying the printed pattern.

[0009] The connecting plate has a through groove on the worktable, and the connecting plate is fixedly installed in the through groove.

[0010] Furthermore, the drying mechanism includes a support plate, which is fixedly installed inside the drying chamber. A worm gear is rotatably mounted on the support plate, and a fan blade is fixedly mounted on the outside of the worm gear. Two electric heating rods are fixedly installed inside the drying chamber.

[0011] Furthermore, a through hole is provided on one side of the inner wall of the drying oven, and a second drive shaft is rotatably installed in the through hole. One end of the second drive shaft is fixedly connected to a worm gear.

[0012] Furthermore, the connecting plate has an internal cavity, and the top inner wall of the cavity has multiple air outlets. A negative pressure pump is fixedly installed at the bottom of the connecting plate, and the output port of the negative pressure pump is fixedly connected to the cavity.

[0013] Furthermore, a drive sprocket and a driven sprocket are fixedly installed at one end of the second drive shaft and one end of the first drive shaft, respectively. The same chain meshes on the drive sprocket and the driven sprocket. When the second drive shaft rotates, the drive sprocket drives the driven sprocket to rotate through the chain.

[0014] Furthermore, a motor is fixedly installed on the top of the support plate, and the output shaft of the motor is fixedly connected to one end of the worm. A worm wheel meshes on the worm, and when the motor is turned on, the worm drives the worm wheel to rotate.

[0015] Furthermore, two symmetrical first drive shafts are rotatably mounted inside the workbench, and conveyor rollers are fixedly mounted on the outer side of each of the two first drive shafts. The same conveyor belt is connected to the two conveyor rollers. When the first drive shafts rotate, the two conveyor rollers are driven by the conveyor belt.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This solution involves starting a motor, which drives a worm gear to rotate, which in turn drives a worm wheel to rotate, which in turn drives a second transmission shaft to rotate, which in turn drives a drive sprocket to rotate. The drive sprocket drives a driven sprocket via a chain, which in turn drives a first transmission shaft to rotate, which in turn drives a conveyor roller to rotate. The conveyor belt then drives the plastic bag to be printed onto the conveyor belt for transport, and the printing machine can then print on the plastic bag on the conveyor belt.

[0018] 2. This solution involves turning on the electric heating rod, which drives the fan blades to rotate. The air pressure generated by the rotating fan blades blows out the heat generated by the electric heating rod, thereby drying the printed patterns or barcodes. At the same time, turning on the negative pressure pump creates a negative pressure suction cavity and multiple air outlets, which can adsorb the plastic bags on the conveyor belt, thereby achieving the purpose of positioning the plastic bags.

[0019] This invention facilitates the drying of printed patterns or barcodes during use and makes it easy to position plastic bags, thereby effectively improving printing quality. It has a simple structure and is easy to use. Attached Figure Description

[0032] In this embodiment, a drive sprocket 19 and a driven sprocket 21 are fixedly installed at one end of the second drive shaft 18 and one end of the first drive shaft 9, respectively. The same chain 20 meshes on the drive sprocket 19 and the driven sprocket 21. When the second drive shaft 18 rotates, the drive sprocket 19 drives the driven sprocket 21 to rotate through the chain 20. A motor 14 is fixedly installed on the top of the support plate 12. The output shaft of the motor 14 is fixedly connected to one end of the worm gear 15. A worm wheel 17 meshes on the worm gear 15.
