How can a direct pressure bronzing machine iron paper well?
Operation of machinery and equipment

(1). When starting the machine, observe whether the machine has abnormal reaction. Whether there is abnormal noise, abnormal action, local overheating, etc. , immediately stop the machine for inspection.

(2) Focus on observing whether the position adjusted in the previous shift is normal.

(3) Check whether the switches and brakes of mechanical equipment are flexible and reliable.

4. Preparation of raw and auxiliary materials

(1). Check whether the products requiring bronze color are in place. If it is not in place, report to the monitor and assist the monitor to carry the products.

(2) The corresponding gilding paper model should be obtained according to different process requirements (such as polishing, gluing, etc.). ), and must fully consider the relationship between the printing part and the hot stamping paper.

(3). Common hot stamping paper model

A. Gold: 368398

B. Red gold: 308368328

C. silver and gold: 368328

(4) Cut the bronzing paper according to the actual area of bronzing, and leave a little margin when cutting, so as to avoid unnecessary waste caused by being too large or too small.

5, machine adjustment

(1). Temperature adjustment. The temperature adjustment of bronzing should be determined according to different products, different technological processes and different bronzing paper models. The bronzing temperature should be determined by the final bronzing product effect.

(2). Pressure adjustment. During pressure debugging, it should be carried out slowly from light to heavy, and finally increased to normal pressure. It is not allowed to adjust the pressure too much at one time, so as not to crush the bronzing plate and cause losses. While adjusting the pressure, we should also pay attention to the balance of the whole layout, and the pressure is the same.

(3) needle position adjustment. The needle position adjustment should be based on the signature sample, the bronzing position is accurate and the needle position is consistent.

(4) When starting work, first iron a few samples and compare them with the original products and the products of the previous shift to prevent dislocation.

6, bronzing products should be considered in advance.

(1) Look at what gold is hot and calculate the required amount in advance.

(2) After printing or gluing, it should be sealed with plastic wrap.

(3) mass production and products that often need coating.

(4) If there are many editions and it is difficult, the film needs to be dried and bound.

Third, the production process

1, the operator shall be responsible for the product quality and the safe operation of the machine.

(1). Responsible for checking the product quality of the previous process, including printing and gluing. If problems are found. Report to the monitor immediately.

(2) Check whether there are waste products or several different papers mixed together in the products that need bronzing treatment. If so, they should be stacked separately, marked and reported to the team leader.

(3) Take charge of sampling the bronzing quality of this machine and pay attention to quality control.

(4) Focus on the following aspects in product inspection:

A. hot stamping paste B. hot stamping is not firm C. handwriting and graphics are incomplete D. hot stamping position is not allowed E. there are dirty spots on the surface

(5)。 Analysis of common quality problems in bronzing

A. paper does not burn gold;

A. check whether the printing oil is dry.

B. check whether the pressure is balanced.

C. check whether the bronzing plate is damaged.

D. check whether the gold paper is related to temperature.

B. Hot stamping paste version:

A. overpressure

B. Excessive temperature

C. There is too much space for layout lines.

C, are not allowed to set of heat:

The bronzing plate is not installed correctly.

B.isn't the stretcher in place

C. Paper deformation or selection

D. Check whether the bronzing plate is larger or smaller than the printing position.

(6)。 Hot stamping post-treatment

Answer: The products to be embossed should be embossed on the machine immediately.

B: the concavity and convexity should keep up with the bronzing.

C: After ironing, check whether it is correct with film.

(7) In strict accordance with the operating procedures, concentrate on the operation and do not grab paper. Ensure the safety of mechanical equipment and life safety.
