Pre-process production method and product line for container sheet material

Abstract

The invention relates to a pretreatment production method of container sheet, comprising the steps as below: S1. The roll material is unreeled, and the continuous strip material is led out; S2. The continuous strip material is fed into a first storing and feeding mechanism; S3. The continuous strip material discharged by the first storing and feeding mechanism is pretreated on the surface; S4. The pretreated continuous strip material is fed into the second storing and feeding mechanism; S5. The continuous strip material discharged from the second storing and feeding mechanism is cut and stacked, or rolled up. The method also comprises a step of S6 between S1 and S2, that is, when two rolls of roll material need to be connected, the two rolls of roll materials are overlapped. The invention also relates to a pretreatment production line of container sheet. By adopting the full production line technology of container sheet pretreatment, compared with the prior art, the pretreatment production line has the advantages that the installed power of production equipment can be reduced by 50%; the occupied area can be decreased by 60%; the labor force can be reduced by 90%, and the productivity can be increased nearly 3 times.

Description

technical field [0001] The invention relates to a production process for container plates, and more specifically, relates to a full assembly line production method and production line for container plate pretreatment. Background technique [0002] With the development of economy and trade, containers, as an important means of transportation, are used more and more widely, and the demand is very large. The production of containers requires a large number of plates, and the existing container plate pretreatment production process mainly includes decoiling, sand blasting and other processes. [0003] Uncoiling production line: firstly, uncoil and unroll the coil; then, cut the opened sheet into a certain length of sheet through the shearing equipment; then, unload and stack the cut sheet. Then, it is necessary to use the lifting machine to lift the sheet to the sand blasting pretreatment line and wait for sand blasting. [0004] Sanding production line: The sheared boards are...

AI Technical Summary

Problems solved by technology

[0005] In the conventional production method of pretreatment of container boards, since uncoiling and sand blasting are scattered operations, after one process is completed, they need to be stacked separately. Separate hoisting, low production efficiency and large production area

Moreover, more workers are needed, and the labor intensity of the workers is high.
