Description

Technical Field

[0001] This utility model relates to the field of adhesive film wrapping machine technology, and in particular to a double adhesive film structure for a wrapping machine that can wrap adhesive film material around the outside of an item. Background Technology

[0002] After large goods are packed into containers, they are typically wrapped with plastic film around the outside of the container to prevent dirt, water, and dust. Previously, this wrapping was done manually, which was inefficient and costly. Therefore, automated machines are now used for this wrapping process, effectively and quickly applying plastic film around the outside of the container.

[0003] Therefore, the applicant in this case has also developed a variety of film wrapping machine technologies, such as the "film clamping and cutting device of film wrapping machine" announced in Taiwan as TWM392147U, the "film clamping and cutting device (I) of film wrapping machine" announced in Taiwan as TWM398517U, the "structural improvement of film wrapping machine" announced in Taiwan as TWM488462U, the "weighing structure of film wrapping machine" announced in Taiwan as TWM571350U, the "corner plate storage mechanism of wrapping machine" announced in Taiwan as TWM6633372U, the "corner plate fixing mechanism of wrapping machine" announced in Taiwan as TWM6633373U, and the "corner plate guiding mechanism of wrapping machine" announced in Taiwan as TWM6633375U, etc.

[0004] However, while all of the aforementioned film wrapping machines can achieve the expected effect of wrapping the items with film, it has been found in actual use that after the items are positioned on the platform, the film wrapping machine on the side is used for bundling. This film wrapping machine is fixed and the film moves up and down to wrap the outside of the items by rotating the platform. However, the film needs to be wrapped several times to securely wrap the items. Therefore, it takes a lot of time to rotate the film, resulting in a decrease in output.

[0005] Therefore, based on the above, and drawing on years of extensive design, development and practical manufacturing experience in the relevant industry, the inventor has provided a double-film structure for a wrapping machine in order to achieve better practical value. Utility Model Content

[0006] The main purpose of this utility model is to provide a double-film structure for a wrapping machine, particularly a wrapping machine technology that can wrap film material around the outside of an item.

[0029] To provide a more complete and clear disclosure of the technical content, purpose, and effects achieved by this utility model, please refer to the accompanying drawings and reference numerals. A detailed description follows:

[0030] First, please refer to Figures 1 to 3 The diagram shows the three-dimensional appearance, front view, and dynamics of a double-film structure of a wrapping machine according to this utility model. It mainly includes a machine base 1, a conveying mechanism 2 for guiding the packaged items inside the machine base 1, and a film mechanism 3 above the machine base 1.

[0031] The film-making mechanism 3 includes a rotating door 31, which has two corresponding base frames 311. Each of the two base frames 311 has a slide rail 312, and a film seat 32 is mounted on each slide rail 312. Packaging film material A is placed inside the film seat 32, and the film material A can be inserted and positioned into a film clamping assembly 4 through the film seat 32. The film clamping assembly 4 is installed on the side of the conveying mechanism 2. Lifting mechanisms 33 are provided in each of the two base frames 311. The lifting mechanisms 33 can drive the film seat 32 to move on the slide rail 312. A rotational power source 34 is connected to the top of the rotating door 31, and the rotational power source 34 drives the rotating door 31 to rotate.

[0032] Please see Figures 1 to 9 In this invention, a film rod 321 is provided on the film holder 32 to support the packaging film A, and multiple guide rods 322 are provided to guide the film A to adjust its tightness. Furthermore, to ensure smooth output of the film A and prevent excessive tension leading to looseness or tightness, an auxiliary power source 35 is provided inside the film holder 32. The output shaft of the auxiliary power source 35 is connected to multiple guide rods 322 for guiding the film A, so that the guide rods 322 can smoothly guide the film A out (e.g., ...). Figure 4 (As shown). Then, the film material A is inserted and positioned on the film clamping assembly 4. The film clamping assembly 4 is mainly used to position the end of the film material A, so that the film seat 32 can drive the film material A to be wrapped around the item B to be packaged.

[0033] The conveying mechanism 2 inside the machine 1 is mainly used to guide the packaged item B into the machine 1 for packaging. The packaged item B varies in size and length. Therefore, in order for the film mechanism 3 to adapt to different sizes of packaged items B and move back and forth for packaging, a rotational power source 34 is installed at the top of the rotating door 31 to drive the rotating door 31 to rotate for packaging. Additionally, lifting mechanisms 33 are respectively installed in the two base frames 311, so that the film seat 32 can be moved on the slide rail 312. Please refer to [further details]. Figure 5 and Figure 6 Furthermore, the lifting mechanism 33 includes a lifting power source 331 installed above the base frame 311. The output shaft end of the lifting power source 331 is connected to a gearbox 332 and a chain drive assembly 333. The diaphragm seat 32 is set on the chain drive assembly 333. When the lifting power source 331 drives the chain drive assembly 333, the diaphragm seat 32 moves on the slide rail 312.

[0034] When actually wrapping item B, such as Figure 3 , Figures 7 to 9As shown in the figure, the packaged item B is guided into the machine 1 by the conveying mechanism 2, so that the packaged item B is located below the film mechanism 3 and inside the rotating door 31. Then, the film mechanism 3 is activated, so that the output shaft of the rotating power source 34 is connected to drive a transmission gear set 341. The transmission gear set 341 can be composed of multiple gears 341A and transmission belts 341B in combination. The top of the rotating door 31 is provided with a shaft 310, which is connected to the transmission gear set 341, so that the rotating power source 34 drives the transmission gear set 341 to drive the rotating door 31 to rotate.

[0035] Before the revolving door 31 rotates, its clamping assembly 4 has already clamped and fixed the end of the film material A in place. Please refer to the attached document. Figure 2 , Figure 6 , Figures 7 to 9 As shown, when the rotating door 31 rotates, the film holder 32 will cause the film material A to be wrapped around the item B to be packaged. This utility model utilizes the simultaneous rotation of the left and right sets of film holders 32, and in conjunction with the lifting mechanism 33, drives the film holders 32 to move on the slide rail 312, so that the film holders 32 can wrap the item B to be packaged from bottom to top and from top to bottom. Thus, the two film holders 32 wrap the film material A around the outside of the item B to be packaged in a spiral and up-and-down manner, achieving the effect of fast packaging and saving time.

[0036] During operation, a cover 36 is provided on the inner side of the base frame 311 of the rotating door 31. The cover 36 provides a shielding effect for the assembly, lifting and lowering of the film seat 32. At the same time, multiple sensors (not shown in the figure) are installed inside the wrapping machine to monitor each action, such as monitoring the size, height, positioning, or film material conveying of the item to be packaged B. A control box (not shown in the figure) is also installed in the wrapping machine. The control box is connected to the above-mentioned sensors to receive the signals from the sensors. The control box is also connected to the rotation power source 34, the lifting power source 331, the auxiliary power source 35, the conveying mechanism 2, etc., to control the wrapping machine to perform the entire process of wrapping the item to be packaged B, thereby achieving automatic wrapping processing.

[0037] The foregoing embodiments or drawings are not intended to limit the implementation of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the protection scope of this utility model.
