1.试生产时最好低速运行,待熟悉机器性能后,可逐渐提高生产速度,如此可较好地保证生产安全和产品的压纹质量。

2.操作时,温度和压力的正确控制十分重要设备,若控制不好很容易发生事故,甚至可能使机器损坏。加热进行压纹定型时,可根据材料特性控制问题,一般情况下将温度控制在40-90℃之间即可,切忌采用超高温进行压纹立体印刷,以防印品变色或变形,避免辊体因受高温影响而变形。压纹时工作压力应根据印品材料的厚薄和密度情况,酌情在3-8mpa范围进行控制,切不可为追求高清晰度的压纹效果而盲目加大压力,以免因压力过重而使压力辊变形。

3.注意处理好机器速度、温度和压力与压纹效果的关系。一般来说电子商务,机器速度慢、温度高、压力大时,压纹效果相对较好,但必须适度,否则,反而影响产品的压纹质量。对紧度高、挺度好的材料排版,机器压力可适当大一些。

4.为防止压力辊变形,长时间停机时,一定要将压力辊离压,其操作程序是:先将油路控制阀松开,使压力辊与花纹辊分离RIP,然后停机。

5.压制不同的花纹更换花纹辊时,可先将滚筒支承横梁上的6颗螺丝松开,把传动链及花纹辊上的加热管卸下,再将花纹辊两端轴承座的上部拆下,随即用皮带或柔软而富韧性的绳子套在滚筒上平衡抬起即可。在拆卸过程中质量控制,切忌用铁辊或其他硬物去撬、垫和碰击花纹辊表面,以防止损坏辊筒纹路。

6.压力辊如出现明显磨损变形时,可进行磨削处理,使其达到均匀压力所需的圆心度。

7.设备使用过程中,应注意定期加注润滑油设备,花纹辊两端轴承每月加注钙基二硫化钼一次,压力辊支承两端、链条输送辊、油杯每日加注30#机油一次,摆线针轮行星减速箱每运转3个月更换机油一次。良好的润滑可提高压纹机的使用性能和寿命,保证产品的压纹质量。

1. It is best to run at a low speed during trial production. After being familiar with the performance of the machine, the production speed can be gradually increased, which can better ensure the safety of production and the quality of the product.
2. During operation, the correct control of temperature and pressure is very important equipment. If it is not controlled properly, it can easily cause accidents and may even damage the machine. When heating for embossing, it can be controlled according to the characteristics of the material. Under normal circumstances, the temperature can be controlled between 40-90 °C. Do not use ultra-high temperature for embossing three-dimensional printing to prevent printing from discoloration or deformation. The roller body is deformed due to high temperature. The working pressure should be controlled in the 3-8mpa range according to the thickness and density of the printing material. The pressure should not be blindly increased for the pursuit of high definition pressing effect, so as not to cause pressure due to excessive pressure. Roller deformation.
3. Pay attention to the relationship between the speed, temperature, and pressure of the machine and the embossing effect. In general electronic commerce, when the speed of the machine is slow, the temperature is high, and the pressure is large, the pressure pattern effect is relatively good, but it must be moderate. Otherwise, it will affect the quality of the product's pressure pattern. For materials with high compactness and good stiffness, machine pressure can be appropriately large.
4. In order to prevent the deformation of the pressure roll, it is necessary to take the pressure roll away from the pressure when it is shut down for a long time. The operating procedure is to first loosen the oil control valve to separate the RIP from the pressure roll and the pattern roll, and then stop the service.
5. When pressing different patterns to replace the pattern roll, you can first loosen the six screws on the roller support beam, remove the heat pipe on the transmission chain and the pattern roll, and remove the upper part of the bearing seat at both ends of the pattern roll. Immediately with a belt or soft and flexible rope on the drum can be balanced lift. Quality control during the demolition process, avoid using iron rolls or other hard objects to pry, pad and hit the surface of the roll pattern to prevent damage to the roller texture.
6. In case of obvious wear and deformation, the pressure roller can be grinding to achieve the roundness required for uniform pressure.
7. During the use of equipment, attention should be paid to the regular filling of lube oil equipment. The bearings at both ends of the pattern roller are added once a month with calcium base Molybdenum disulfide. The pressure roller supports both ends, the chain conveyor roller, and the oil cup are added once a day with 30 # oil. The cycloid needle wheel planet speed box changes the oil once every 3 months. Good lubrication can improve the performance and life of the press, and ensure the quality of the product.
