Industrial code-spraying equipment

Abstract

The invention discloses industrial code-spraying equipment which comprises a conveying belt (1) and a high-definition spray printing machine (2). A fixed bracket (9) is mounted at one side of the conveying belt (1), an arc plate bracket (4) is assembled on a guide rail (3), provided with a bracket offsetting spring (5) at a part in contact with the guide rail (3) and connected with an arc plate (6), and the high-definition spray printing machine (2) is mounted on the arc plate (6) which is provided with a high-definition spray printing machine ink jet hole (7) in the middle. In the invention, under the condition that an ink jet product production line is not changed, the impact and the vibration of a spraying head are effectively eliminated, the distance change between the spraying head and the product, which is caused by the size deviation of the sprayed product, can be automatically eliminated, the spraying head is constantly attached to the product so that clear ink jet effect is kept, and the high-definition code-spraying machine can be well used in an impact and vibration environment.

Description

technical field [0001] The invention relates to a code spraying device, in particular to an industrial code spraying device which can well code irregular commodities. Background technique [0002] In industrial production, many items need to be printed on the company's relevant expiration date, batch number, barcode, pattern, trademark, count, shift, text and other information before leaving the factory, so the inkjet equipment is widely used. But in normal use, because the high-definition jet printer has higher requirements on the environment used, such as 1, the nozzle diameter of the nozzle of the existing high-definition jet printer is small (50 μm), thus requiring the effective distance of its jet printing must be Within 6mm, the smaller the distance, the better the printing effect; 2. The nozzle has high precision and can only be used in an environment without shock and vibration. In this way, the nozzle must be installed on a fixed support without shock and vibration....

Problems solved by technology

But in normal use, because the high-definition jet printer has higher requirements on the environment used, such as 1, the nozzle diameter of the nozzle of the existing high-definition jet printer is small (50 μm), thus requiring the effective distance of its jet printing must be Within 6mm, the smaller the distance, the better the printing effect; 2. The nozzle has high precision and can only be used in an environment without shock and vibration. In this way, the nozzle must be installed on a fixed support without shock and vibration. If the nozzle Vibration will cause air to enter the ink chamber of the nozzle, resulting in unclear or even no printing content, so the high-definition jet printer is subject to more restrictions in use

Because the high-definition inkjet printer has the above two strict requirements, the high-definition inkjet printer adopts a fixed installation method when it is applied on the production line, and adjusts the position of the object to be printed by rectifying the production line to achieve the effective printing distance of the nozzle , if the size deviation of the object to be printed is greater than 6mm, then the clear printing content will not be obtained, or even unusable, so the application of the high-definition inkjet printer on irregular objects is greatly limited

Taking pulp bales as an example, the nozzle support of the existing high-definition inkjet printer is fixed on the side of the conveyor belt. Since the size deviation of the printed product itself is ±20mm, the effective printing distance of the nozzle must be within 6mm. Therefore, it often happens that the distance between the printed product and the nozzle is too large, and the printing content is blurred, or the printed product collides with the nozzle, causing the nozzle to vibrate violently, so that the ink chamber of the nozzle contains more air, causing Each shift requires frequent ink discharge and purification to discharge the air in the ink chamber of the nozzle. Based on the daily printing of 3,000 trademarks, it needs to be purified at least about 92 times. On average, ink discharge and purification is required for every 32 trademarks printed. Huge ink loss, resulting in a bottle of ink can only print about 2917 trademarks, and the average printing cost of each trademark is about 1.2 yuan
