At present, domestic pharmaceutical companies, as long as they produce Chinese patent medicines, generally have granules and a few powders. There are many brands of packaging machines produced in China. From the aspects of function, configuration and various aspects, the difference is relatively large. The selection of granule and powder packaging machines suitable for the company's products is the key to production yield and packaging quality.
At present, domestic packaging machines are divided into the form of sealing and can be divided into a splint type and a roller type. From the production capacity, it can be divided into single-row machines and multi-row machines. From the way of film removal, it can be divided into vertical machine and horizontal machine. At present, the main forms of pouch packaging are: three-side seal, four-side seal, and back seal.
The following describes the characteristics of each model separately:
Plywood vertical single-row packaging machine: intermittent sealing, volumetric metering, filling and unloading, splint sealing, small size, simple operation and short service life. Different manufacturers, different brands and configurations, different prices, the current domestic prices range from 0.8 million to 16,000.
Single-row roller packaging machine: Compared with the plywood type, the continuous sealing, the packaging looks beautiful, the speed is generally 40-90 bags / min (depending on different materials and packaging size), the current domestic price is 20,000-60,000 yuan The price varies from manufacturer to manufacturer and from manufacturer to brand. Compared with the plywood machine, this kind of packaging machine requires the operator to have certain ability, and the after-sales service and maintenance requirements are relatively high.
Multi-row packaging machine: Through the previous national pharmaceutical machinery exhibition, there are more and more manufacturers of multi-row packaging machines in China, and the product grades are also quite different. The price ranges from 100,000 to 500,000. The main difference in price is From the difference in configuration, the difference in appearance, the difference in materials used, if you want to choose to buy multi-row machines, it is recommended to buy machines with better quality. Although the first investment is several tens of thousands, it is guaranteed for subsequent stable operation.
So how do pharmaceutical companies choose the packaging machine that suits them?
The output of a single variety is relatively large, and the company's main products are granules or powders. At present, there are all-aluminum appearance multi-row packaging machines in China, all of which are equipped with imported components. The performance is in the domestic lead in the same industry. The SK900 packaging of Chengdu Sanke Industrial Co., Ltd. exhibited at the 32nd National Pharmaceutical Opportunity in Suzhou The machine is truly different. It is equipped with automatic rectification, film changing mechanism and fine workmanship, which can meet the quality and performance requirements of imported packaging machines.
There are many varieties, and the output of each variety is not large. Pharmaceutical companies can consider purchasing vertical single-row packaging machines, such as the domestic three bridges, etc., to meet the requirements.
For start-ups of new varieties or for those with insufficient capital, consider buying a splint-type packaging machine. Whether it is a multi-row packaging machine or a single-row packaging machine, as long as it is a mature model and technology, it basically meets the requirements from the accuracy error, but in terms of packaging speed, it is packaged with 5g/bag granules (bag length 80mm × bag) For example, width 60mm), vertical single-row roller packaging machine, between packaging speed (60-90 bags / min), vertical splint packaging machine (50-80 bags / min), SK900 series packaging machine Achieve between 350-420 bags / min.
At present, the problem of batch number printing on the packaging machine has been solved. After repeated trials by the pharmaceutical company, it is better to choose the ink wheel type code printer than the ribbon type. Of course, you can also choose the hard pressure word to realize the batch number imprint of one to two rows. .
Powder packaging has always been a difficult problem to solve. From the point of view of the pharmaceutical factory, if it is necessary to solve the problem that the powder is difficult to be cut in the packaging process, the sealing is not strict, and the material is trapped, it is recommended to select a single-row horizontal packaging machine. The advantage of this type of machine is that the bag is firstly cut and then unloaded. The cutting material is driven by the servo motor to reduce the drop of the powder. The blanking head is directly inserted into the bag, and the material is put back into the original position. The powder package is generally between 200 and 400 mesh. Such models can be considered, such as the domestically produced SK11 series packaging machine. For the powder packaging with large output, it is possible to consider the use of multi-row packaging machines. It is understood that the current multi-row powder packaging machine has matured and applied in the domestic seven-row powder packaging machine. The structure is reasonable, each column has a separate The servo system, PLC control, and fine workmanship are the classic models of the domestic four-side sealing multi-row powder packaging machine.
