铝塑泡罩包装机应用中的常见问题
Common problems in application of blister packaging machine
铝塑泡罩包装机由于生产厂商的不同而存在着很多种形式,国内外产品的性能水平也存在着很大的差异,目前现有的铝塑泡罩包装机大体可以分为如下四类:滚筒连续式铝塑泡罩包装机(此种机型已逐步淘汰)、板滚连续式铝塑泡罩包装机、平板间歇式铝塑泡罩包装机、平板连续式铝塑泡罩包装机(此种机型尚未广泛使用)。
Aluminum-plastic foam cover packaging machine exists in many forms because of different manufacturers, and the performance level of domestic and foreign products is also very different. At present, the existing aluminum-plastic foam cover packaging machine can be divided into the following four categories: roller continuous aluminum-plastic foam cover packaging machine (this model has been phased out), plate roller continuous aluminum. Plastic foam cover packaging machine, flat intermittent aluminum foam cover packaging machine, flat continuous aluminum foam cover packaging machine (this type of machine has not yet been widely used).
铝塑泡罩包装机可以按成型和热压封合方式来区分,成型分为滚筒式和平板式。平板式正压成型效果好于滚筒式真空成型;热合也分为滚筒式和平板式平板式热压封合效果好于滚筒式热压封合,而滚筒式热压封合在速度、可靠性等方面优于平板式热压封合。
Aluminum plastic bubble cover packaging machine can be distinguished by forming and hot-pressing sealing methods, forming into roller type and flat type. The positive pressure forming effect of the flat plate is better than that of the vacuum forming of the roller, and the hot sealing effect of the flat plate and the roller is better than that of the flat plate, while the roller is better than the flat plate in speed and reliability.
根据生产经验,发现铝塑泡罩包装机在使用中容易在泡罩成型、热压封合等方面出现问题,下面简要介绍如何解决这些问题。
According to the production experience, it is found that the aluminum-plastic foam cover packaging machine is easy to be used in the foam cover molding, hot-pressing sealing and other aspects of problems, the following brief introduction of how to solve these problems.
1、 泡罩成型
1. Blister molding
根据泡罩成型是PVC薄膜(硬片)加热后通过模具并利用压缩空气或真空成型为所需要形状、大小的泡罩的原理,因此当成型出的泡罩出现问题时需要从以下几方面着手解决:
According to the principle that the foam cover is formed by heating the PVC film (hard piece) through the mold and using compressed air or vacuum to form the desired shape and size of the foam cover, the problem of forming the foam cover needs to be solved from the following aspects:
(1) PVC薄膜(硬片)是否为合格产品;
(1) whether PVC film (hard film) is a qualified product;
(2) 加热装置的温度是否过高或过低;
(2) the temperature of the heating device is too high or too low;
(3) 加热装置的表面是否粘连PVC;
(3) whether the surface of the heating device is adhered to PVC;
(4) 成型模具是否合格,成型孔洞是否光滑,气孔是否通畅;
(4) whether the mold is qualified, whether the molding hole is smooth, and whether the porosity is smooth.
(5) 成型模具的冷却系统是否工作正常、有效;
(5) whether the cooling system of the mould is working normally and effectively;
(6) 滚筒式负压成型的真空度、排气速率能否达到正常值,管路有无非正常损耗;
(6) Whether the vacuum and exhaust rate of the roller negative pressure forming can reach the normal value, and whether the pipeline has abnormal loss;
(7) 平板式正压成型的压缩空气是否洁净、干燥,压力、流量能否达到正常值,管路有无非正常损耗;
(7) Whether the compressed air formed by plate positive pressure is clean and dry, whether the pressure and flow can reach the normal value, and whether the pipeline has abnormal loss;
(8) 平板式正压成型模具是否平行夹紧PVC带,有无漏气现象。
(8) flat plate positive pressure molding die is parallel clamping PVC belt, whether there is air leakage phenomenon.
2、热压封合
2. Hot pressing and sealing
在滚筒式铝塑泡罩包装的热压封合过程中,PVC带与铝箔是由相互平行的滚筒状热封辊和网纹辊在一定温度和压力作用下作啮合式对滚来完成热压封合的。热封辊和网纹辊的接触为线性接触,所需要的压力相对较小。
In the process of hot-pressing sealing of roller-type aluminum-plastic foam cover packaging, PVC belt and aluminum foil are made of parallel roller-like hot-sealing rollers and mesh rollers to engage in a certain temperature and pressure to complete the hot-pressing sealing. The contact between heat seal roller and anilox roller is linear, and the pressure needed is relatively small.
在平板式铝塑泡罩包装的热压封合过程中,PVC带与铝箔是由相互平行的平板状热封板和网纹板在一定温度和压力作用下在同一平面内来完成热压封合的。热封板和网纹板的接触为面状接触,所需要的压力相对较大。
In the hot-pressing sealing process of flat aluminum-plastic bubble cover packaging, PVC strip and aluminum foil are sealed by parallel flat hot-sealing plate and reticulated plate in the same plane under certain temperature and pressure. The contact between heat seal plate and netted plate is surface contact, and the pressure needed is relatively large.
不论是滚筒式还是平板式热压封合,当出现热封网纹不清晰、网纹深浅不一、热合时PVC带跑位造成硌泡等问题时需要从以下几方面着手解决:
Whether it is drum type or flat type hot-pressing sealing, the following problems should be solved when the hot-sealing mesh is not clear, the mesh depth is different, the PVC belt runs away and causes blisters when the hot-sealing occurs:
(1) 铝箔是否为合格产品,热合面是否涂有符合要求的热溶胶;
(1) whether the aluminum foil is a qualified product and whether the heat sealing surface is coated with the required hot melt adhesive;
(2) 加热装置的温度是否过高或过低;
(2) the temperature of the heating device is too high or too low;
(3) PVC带或铝箔的运行是否有非正常的阻力;
(3) is there any abnormal resistance in the operation of PVC tape or aluminum foil?
(4) 热封模具是否合格,表面是否平整、光滑,PVC带上成型出的泡罩能否顺利套入热封辊(板)的孔洞内;
(4) whether the hot-sealing die is qualified, whether the surface is smooth and smooth, whether the foam cover formed on the PVC belt can be smoothly inserted into the hole of the hot-sealing roller (plate);
(5) 网纹辊(板)上的网纹是否纹路清晰、深浅一致;
(5) the veins on the roller (plate) are clear and uniform in texture.
(6) 热封模具的冷却系统是否工作正常、有效;
(6) whether the cooling system of the heat sealing mould works normally and effectively;
(7) 热封所需的压力是否正常;
(7) the pressure required for heat sealing is normal.
(8) 热封辊(板)和网纹辊(板)是否平行。
(8) whether the heat sealing roller (plate) and anilox roller (plate) are parallel.
3.有些技术先进的铝塑泡罩包装机装备有各种自动监控装置,能够起到各种保护作用,在发现下列问题时自动停止机器的运行:
3. Some advanced aluminum-plastic foam cover packaging machines are equipped with various automatic monitoring devices, which can play a variety of protective roles and automatically stop the operation of the machine when the following problems are found:
(1) 安全防护罩打开;
(1) open the safety shield.
(2) 压缩空气压力不足;
