4. Easy-to-appear problems of paper barrels and countermeasures

In the process of using the paper barrel, there is a problem that the paper barrel during the carrying process is deformed greatly, and the barrel body and the bottom of the barrel are easily detached, especially the bottom of the barrel is disconnected from the joint of the pentaphyllal board, causing quality problems. The main reasons for analyzing the following are:

4.1 Effect of quality of plywood on bottom quality:

When the bottom end of the drum is made of penta-plywood, the problem of the material of the penta-plywood is:

1 uneven thickness, most of the thickness can not meet the requirements.

2 The adhesive strength between the plywood layer and the layer is low, and it is detached.

3 Five-plywood wood differential affects its strength.

4 The tolerances of the size of the quintile blanks are inaccurate.

Solution: First of all, we must use the standard pentathronous material. The size of blanking should be strictly controlled within the tolerance range, and quality monitoring should be carried out. The thickness of pentahedron should be determined according to the maximum weight of the content of the drum, when the content of the content of the drum is When about 50 kg, the thickness of the plywood should not be less than 6 mm.

4.2 The effect of the quality of the barrel forming process on the bottom of the barrel.

In the production process of the barrel, the connection between the barrel body and the bottom of the barrel mainly depends on the back cover forming process, so the operation quality of the forming and sealing process affects the overall quality of the barrel. After the equipment type is determined, the size change of the various parts of the paper sealing mold should be inspected frequently. Because the mold is closed at the bottom of the closing paper barrel, the lock ring mold may be vertically and easily deviated, resulting in different binding and looseness of the bottom of the paper bucket, thereby affecting the bucket. The end is in line with the barrel.

4.3 Establish various technical quality management systems and conduct effective control.

Specifically speaking, the management system for the entire production process must be established, including the raw material procurement system, key process control system, incoming inspection system, first inspection system, operator self-checking system, process mutual inspection system, and quality inspector inspection system. Finished product inspection system. The control procedures of the management system shall be established, and the methods and procedures for the approval, publication, marking, cataloging, use, modification, recovery, filing, storage and handling of the system shall be established. In the same place where the management system must be promptly issued and revoked, it is necessary to ensure that all sites use the effective version of the corresponding system.

4.4 process control for the entire production process

Firstly, formulate the technical operation procedures and inspection standards for each process in the production process, establish key processes that affect product quality, and conduct continuous supervision to ensure that each process in the production process is in a controlled state and the control status of the production process on a regular basis. Conduct effective audits and take corrective measures in time to resolve abnormal situations and problems, and make assessment records.

4.5 Establishing raw materials and finished product inspection systems and methods

Formulate the inspection system for raw materials and record the inspections. The accuracy and precision of the testing equipment should meet the inspection requirements and be checked regularly. Process inspection includes the first inspection, self inspection, mutual inspection, inspection and clear records.

The methods of product inspection are mainly divided into appearance inspection and performance inspection, and the internal control indicators for inspection are higher than those of national standards. The following describes the inspection methods, inspection requirements, and guidelines for the barrels. (To be continued)
