Widely used in food, tobacco, medicine and other products wrapping. There are many types of wrapping machinery with different functions, and the packaging equipment that uses flexible packaging machinery to wrap all or part of the wrapping products is collectively referred to as wrapping machinery. Wrapping machinery is one of the most important components in the packaging machinery and equipment industry. The common feature of wrapping machinery is that one or more solid items are wrapped with thin flexible packaging materials (such as cellophane, plastic molds, mucous films, various composite films, etc.). It not only improves production efficiency, but also prevents damage to goods in the handling process, and plays a dust-proof, moisture-proof and cleaning role. And items with a certain rigidity are packaged. Some powder and bulk granular items are pre-packaged after shallow plates, boxes, etc., and the wrapping machinery is suitable for blocking. Can be packed as lumps. Block items come in different shapes, such as square, cylindrical, spherical, etc., and can be a single item or a collection of several items. For example, candy and soap are single wraps, and travel biscuits, matches, etc. are arranged and combined for collection wraps. In addition, cigarette boxes, tea boxes, etc. can also be wrapped. Flexible materials (cellophane, etc.) for wrapping have developed, so that many new wrapping machines and related machinery have been developed, these new machinery has the characteristics of high speed, high efficiency, and greater adaptability to the change of the size of packaged items.
Focus on development. Since the 90s, wrapping machinery has attracted the attention of the industry at the end of the 70s. With the expansion of the introduction scale and the improvement of the infrastructure of the production enterprise from time to time, especially the promotion and application of PLCPC, the function of wrapping machinery tends to be more perfect and develops towards automation and intelligence. In the future development of wrapping machines, in addition to plastic film wrapping equipment, it is necessary to develop origami wrapping equipment. Vigorously develop various auxiliary devices matching with wrapping equipment to expand the application of host functions.
The rapid development of the packaging industry in modern society. As well as the rapid development of the food packaging industry, the requirements for packaging machinery and equipment are getting higher and higher. Below I will introduce in detail the development status of the packaging industry in the future. The wrapping machine can be called the wrapping machine or the winding machine.
Points to note when wrapping machine (winding machine) is safe to use:
1. It is forbidden to test the voltage between the DC motor control board and the PLC input point and the ground wire.
2. Before operating the inverter, be sure to read the random frequency conversion manual in detail.
Be sure to tighten if any.
3. When the wrapping and winding machine is in normal use, regularly check whether each connection part of the machine is public or falling off.
4. It is strictly forbidden to move or remove the upper and lower fixed limit blocks
5. The turntable of the wrapping and winding machine should run in a clockwise direction.
6. It is strictly forbidden to stand people or stack any objects under the film system.
To prevent damage to the roller or fingers. 7. When the rotary roller of the film system rotates, it is strictly forbidden to reach inward or reach into other objects, or perform other operations.
8. It is strictly forbidden to put your hand near the chain for repair or inspection during operation to prevent injury to your hand. When the machine is completed, the working process is completed, and when stopping, close to the machine to prevent the cargo from scattering and injuring people.
9. When the wrapping and winding machine is running, the operator should stand in a safe place at a certain distance from the turntable. If necessary, the safety isolation net should be installed according to the installation (self-provided or customized separately)
10. It should be firmly grounded or connected to zero (zero ground shall not be mixed) to prevent leakage from damaging the machine or personnel. And make sure that it is safe before use.
11. When the wrapping and winding machine is moved away from its original position, the machine should be reinstalled and tested by professionals.
12. Regularly check electrical and electrical connections, clean electrical cabinets!
The current annual demand for winding film is about 200,000 tons. Compared to foreign countries, experts predict. There is considerable room for development of this capacity. China's winding packaging industry started in the late 80s of the twentieth century and developed rapidly in the 90s. At present, the total annual consumption of winding film in the country is about 60,000 tons, of which more than 40% is imported. New investments have entered the fierce competition in various film packaging markets, from suppliers to users are optimistic about the winding film market. Domestic foresight enterprises have begun to increase investment in the winding film market.
