Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing injection - molded inner liners of type Ⅳ hydrogen storage bottles, and particularly relates to an integrated weighing, inkjet coding and detection machine for injection - molded inner liners of type Ⅳ hydrogen storage bottles after injection molding. Background Technique

[0002] In the production process of the inner liner of a type Ⅳ hydrogen storage bottle, after injection molding, the cylinder body and the end head need to go through a cutting process to remove the redundant parts, and then are weighed, dimensionally inspected, and inkjet - coded to judge the product's compliance and assign it an identity label. Currently, on the market, separate equipment is provided for these processes. For example, an electronic scale is used for weighing, a line laser scanner is used for dimension inspection, and a laser inkjet printer is used for inkjet coding.

[0003] However, there are many deficiencies in using these three devices separately in the prior art. First, from the perspective of production efficiency, operators need to move frequently between different single - unit devices, which not only increases the operation time but also reduces the overall production efficiency. Second, the management cost increases significantly because multiple devices need to be monitored and maintained separately, and at the same time, their coordinated operation needs to be ensured. In addition, for inner liners of type Ⅳ hydrogen storage bottles of different sizes, different devices may need to be replaced or adjusted to meet the production requirements, which further increases the equipment cost and operation complexity.

[0004] More importantly, using these devices separately cannot achieve real - time sharing and automated processing of information. For example, the weighing results, inspection results, and inkjet - coding information need to be manually recorded and transmitted, which is prone to human errors and is not conducive to data traceability and analysis.

[0005] In view of the above problems, the utility model proposes an integrated weighing, inkjet coding and detection machine for injection - molded inner liners of type Ⅳ hydrogen storage bottles after injection molding. Content of the Utility Model
