1. The condition of the machine and the quality of the product
(1) Firstly, check whether the machine is operating normally during the previous shift, whether any abnormal situations have occurred, and the measures and methods for handling abnormal situations.
(2) Check the quality of the products from the previous shift. Check whether the product quality of the previous shift meets the quality requirements and whether there are any scrap or defective products. Are waste products, defective products, and qualified products stacked separately, and their quality and quantity should be indicated on the process flow sheet.
2. Production progress of this machine
Check the product content and planned completion status of the previous shift on this machine, have a clear understanding of the production progress of this batch of products, and make arrangements for the production plan of this shift.
3. Adjustment of computer stamping machine
It is necessary to have a specific understanding of whether the machine equipment has been adjusted during operation at work, if any, which components have been adjusted, and the usage and operation after adjustment.
2、 Preparation work before production
1. Before going to work every day, it is necessary to refuel and lubricate the stamping machine. Refueling should be done seriously, comprehensively, and without leakage. At the same time, it is necessary to observe whether the oil hole is blocked. Once found, it should be removed and dredged.
2. Carefully read the construction order and accurately understand the requirements of the work order
(1) The captain should accurately understand the requirements of the construction order before starting the machine, and check whether the samples and work orders are complete and consistent.
(2) Check the hot stamping version against the original manuscript. Check if the hot stamping version meets the quality requirements.
(3) When the requirements of the construction order cannot be fully understood, the team leader and supervisor should be consulted clearly, and production should not be based on subjective assumptions.
3. Operation of machinery and equipment
(1) When the machine is first started, it should be observed for any abnormal reactions. If there is any abnormal noise, abnormal action, local overheating, etc., it should be immediately stopped for inspection.
(2) Focus on observing whether the adjusted parts of the previous shift are normal.
(3) Check whether the switches, brakes, and other components of the machine equipment are flexible and reliable.
4. Preparation of raw and auxiliary materials
(1) Check if the products that require stamping are in place. If they are not in place, report to the team leader and assist them in handling the products.
(2) The corresponding model of hot stamping paper should be obtained according to different process requirements (such as polishing, gluing, etc.), and the relationship between the printed piece and the hot stamping paper must be fully considered.
(3) Commonly used models of gilding paper
A. Gold: 368398
B. Red gold: 308368328
C. Silver and gold: 368328
(4) According to the actual area of the hot stamping, the hot stamping paper should be cut with a slight excess during cutting to avoid unnecessary spreading due to being too large or too small.
5. Machine adjustment
(1) Temperature regulation. The temperature adjustment of hot stamping should be determined based on different products, processes, and types of hot stamping paper. The temperature of hot stamping should be determined by the effect of the final hot stamping product.
(2) Pressure regulation. When debugging under pressure, it is necessary to move from light to
