Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to an automatic film feeding adjustment machine. Background Art

[0002] After many products are produced, they need to be packaged in order to protect them. A packaging machine is a machine that packages products, so it is widely used in various fields. Among the existing packaging equipment, according to the form of packaging bags, it can be divided into mixed packaging and continuous packaging. Mixed packaging is to package multiple parts in the same packaging bag, and continuous packaging is to seal a longer bag and separate it into multiple small packaging bags, and multiple parts are packaged in different packaging bags.

[0003] Especially for continuous packaging, since product information needs to be printed on the packaging bags, the usual process is to feed the packaging film through a film feeding device, and after coding, it is fed into a heat sealing device, and the heat sealing device completes the bag forming and sealing process; since the size and required quantity of each component are different, in order to reduce waste, the packaging bag length corresponding to each component will be set during production, but this also requires adjusting the coding position when changing orders, so that the packaging film length between the coding machine and the heat sealing device is an integer multiple of the total length of the continuous bag, so that the coding information can be accurately displayed in the middle of the bag; however, existing equipment all uses manual adjustment. After changing orders, workers manually adjust the packaging film length between the coding machine and the heat sealing device. Not only is the adjustment efficiency low, but the success of the adjustment depends entirely on the workers' experience, which easily leads to a large amount of packaging film waste; therefore, there is an urgent need for an automatic film feeding adjustment machine to solve the above problems.

[0034] Reference Figures 1 to 2 , an automatic film feeding and adjusting machine, comprising a frame 100, a film feeding device 200, a coding device, a heat sealing device 300 and an electric control regulating device 400;

[0035] The film feeding device 200 is provided on the frame 100 and is used to feed the packaging film;

[0036] The coding device is provided on the frame 100 and is used to code the packaging film;

[0037] The heat sealing device 300 is arranged on the frame 100 and is opposite to the film outlet end of the film feeding device 200, and is used to heat-seal the packaging film into a packaging bag;

[0038] The electric control regulating device 400 is disposed on the frame 100 and between the film feeding device 200 and the heat sealing device 300 , and is used to adjust the length of the packaging film between the film feeding device 200 and the heat sealing device 300 in an electric control manner.

[0039] The present invention provides an automatic film feeding adjustment machine connected to the rear end of the feeding device of the packaging machine. The feeding device counts various parts and then conveys them to the feed end of the heat sealing device 300, while the film feeding device 200 continuously conveys the packaging film on the packaging film roll 500 to the heat sealing device 300. During the conveying process, the packaging film is first coded by a coding device (not shown in the figure). The coded packaging film is then wound around the electric control adjustment device 400 and then conveyed to the heat sealing device 300. The packaging bag is formed and heat-sealed by the heat sealing device 300 to complete the packaging.

[0040] Specifically, when the order information is input into the packaging machine, the number of connected packages included in the order, the number of small packages in each connected package, the size of the small packages, the weight and quantity of parts in the small packages, etc. will be known, and then the total length of the connected package will be known. For example, in one embodiment, the connected package contains 10 small packages with a total length of 300 mm, and the position of the coding device on the frame 100 is used as the starting point, and the position of the heat sealing device 300 on the frame 100 is used as the end point. The length of the packaging film between the two is fixed (without adjusting the winding method of the packaging film), for example, 1000 mm. Since the length of the packaging film between the two needs to be an integer multiple of the total length of the connected package, the length that needs to be adjusted by the electronically controlled adjusting device 400 is 1000-300*3=100 mm, that is, the electronically controlled adjusting device 400 needs to adjust the transition roller downward. 420, shortening the length of the packaging film between the coding device and the heat-sealing device 300 by 100 mm; in another embodiment, the continuous package contains 10 small packages with a total length of 400 mm. At this time, the length that needs to be adjusted by the electronically controlled adjusting device 400 is 1000-400*2=200 mm, that is, the electronically controlled adjusting device 400 needs to adjust the position of the transition roller 420 downward to shorten the length of the packaging film between the coding device and the heat-sealing device 300 by 200 mm; the advantage of the utility model is that: through the above structure, the length of the packaging film between the film feeding device and the heat-sealing device can be automatically adjusted to a multiple of the total length of the packaging bag, so that the coding information on the packaging film is displayed in the middle of each packaging bag, which not only greatly improves the adjustment efficiency when changing orders, but also reduces the waste of packaging film, and has very good practicality.

[0041] In some embodiments, the film feeding device 200 includes a plurality of film feeding rollers 210 ; good tension and smooth film feeding are provided by properly arranging the plurality of film feeding rollers 210 .

[0042] In some embodiments, the coding device is configured as a laser coding mechanism.

[0043] In some embodiments, the heat sealing device 300 includes a forming mechanism, a longitudinal sealing mechanism 310 and a transverse sealing mechanism 320; the forming mechanism is used to construct the packaging film into a semi-formed film with openings at the front end, the rear end and the side ends; the longitudinal sealing mechanism 310 is used to heat-seal the side end openings of the semi-formed film; the transverse sealing mechanism 320 is used to heat-seal the front end and the rear end openings of the semi-formed film; in this embodiment, the packaging film coded by the coding device is adjusted in length by the electronically controlled regulating device 400 and then enters the forming mechanism, and the two sides of the packaging film are folded toward the middle of the packaging film and partially re-sealed by the forming mechanism. The side openings of the semi-molded film are stacked to form the side openings, and the front and rear ends of the packaging film also have openings. Among them, the side openings of the semi-molded film are heat-sealed by the longitudinal sealing mechanism 310, and the front and rear end openings of the semi-molded film are heat-sealed by the transverse sealing mechanism 320. It should be noted that after the transverse sealing mechanism 320 seals for the first time, the first type of component is fed in, and the packaging bag moves forward by the length of the first small package, and then sealed for the second time. At this time, the second type of component is fed in, and the packaging bag moves forward by the length of the second small package, and then sealed for the third time. This cycle is repeated to finally complete the packaging of the continuous package.
