Description

Technical Field

[0001] The invention relates to the technical field of improved design of automatic packaging machinery for aluminum profiles, and in particular to a packaging process and a packaging production line for aluminum profiles. Background Art

[0002] The packaging process of aluminum profiles mainly involves cutting packaging paper, putting aluminum profiles on shelves, folding paper, wrapping with tape, and framing aluminum profiles. For the two packaging prerequisite processes of paper cutting and loading, the reduction of efficiency of one process will affect the efficiency of the other process. A bundle of qualified packaging profiles must go through at least 7-8 wrapping wrapping processes. At present, the single-station wrapping packaging mechanism cannot significantly improve the efficiency of automatic packaging.

[0003] Therefore, we propose an aluminum profile packaging process and a packaging production line to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to propose an aluminum profile packaging process and packaging production line, which combines paper folding and tape wrapping into one process, adopts a three-station paper folding packaging mechanism, and improves packaging efficiency.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a packaging process for aluminum profiles, comprising the following steps: S1. The paper tape is pulled and cut to form packaging paper, and the aluminum profile is adjusted to have an axial position to align the two ends of the packaging paper and conveyed forward; S2. The aluminum profile is placed on the packaging paper and pulled together to the folding and packaging station, folded and taped before conveying; S3. The traction and conveying are carried out according to the set length, and the folding and taping are continued in sections until completion; S4. The packaged aluminum profile is conveyed and pushed onto the pad; S5. After the number of aluminum profiles on the pad reaches the set value, the material is dropped onto the hydraulic lifting platform, and after the number of aluminum profile layers on the hydraulic lifting platform reaches the set value, the material is dropped into the material frame.

[0006] In step S1, the packaging paper and the aluminum profile are conveyed synchronously. In step S2, the front end of the aluminum profile is firstly subjected to the paper folding and tape wrapping operation, and then continues to move forward for a certain distance before being subjected to the paper folding and tape wrapping operation again. In step S3, the traction distance is calculated by the encoder, and when it is pulled to the set distance, it stops and the paper folding and tape wrapping operation is performed again.

[0007] In step S1, a paper cutting device is used to draw a paper tape and cut it to form wrapping paper. The paper cutting device includes: a paper feeding mechanism that draws the paper tape on a paper tube roll through a roller group; a paper cutting mechanism that includes a blade group for cutting the paper tape; and a paper feeding mechanism that includes a paper skin clamp that moves along an elliptical orbit to draw the paper tape.

The traction device includes a lower bracket, and the lower bracket drives the upper bracket to move up and down through a rotary cylinder. Two oppositely arranged material clamping mechanisms are installed on the upper bracket, and the adhesive pad material clamps of the material clamping mechanisms can clamp the packaged aluminum profiles. In steps S4 and S5, the packaged aluminum profiles are pulled and framed by an automatic framing device. The automatic framing device includes a transfer mechanism. The lifting plate of the transfer mechanism can lift the packaged aluminum profiles and then horizontally move them onto the cushion strip, and then push the aluminum profiles onto the hydraulic lifting platform through a pushing mechanism.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] Refer to Figure 1 - 26 As shown, for a packaging production line of aluminum profiles, each sub-mechanism is described in terms of its structural composition and working steps through separate embodiments according to the packaging process flow.

[0045] Example 1, paper cutting device 2. The paper tape on the paper roll 21 of the paper feeding mechanism of the paper cutting device is traction-transported through the upper paper roller 25 and the belt sprocket roller 22. The sprocket of the belt sprocket roller is driven by the first chain 23 and the first sprocket 24. The first sprocket is driven after being speed-reduced by a motor. The belt sprocket roller is provided with three arranged in an arc-shaped trajectory. The upper paper roller is connected to the first cylinder 26 and can be lifted to contact the belt sprocket roller. Driven by the belt sprocket roller, the paper tape is traction-transported; the paper cutting mechanism includes an upper blade 27 and a lower blade 210 located on the upper and lower sides of the paper tape. A guide roller 29 is also provided between the lower blade and the paper feeding mechanism. The guide roller is a component that supports and assists in feeding the paper tape before cutting. The upper blade is driven by the second cylinder 28 to cooperate with the lower blade to cut the paper tape; the paper feeding mechanism includes a first paper skin clamp 213 and a second paper skin clamp 214 with the same structure arranged on the elliptical track. Both are traction-transporting the paper tape by moving around the elliptical track through the transmission mechanism. The elliptical track includes an outer elliptical guide rail 215 and an inner elliptical guide rail 214. The inner elliptical guide rail is located inside the cavity of the outer elliptical guide rail and is fixed by the frame 219. A pressing piece 211 is provided on one side of the outer elliptical guide rail close to the paper cutting mechanism. The pressing piece is driven by the third cylinder 212 to move up and down. A convex part is provided on the side of the outer elliptical guide rail far from the paper cutting mechanism. The first paper skin clamp clamps the paper tape by the first upper clamping plate 2132 and the first lower clamping plate 2135 that are elastically hinged. The first upper clamping plate moves along the outer elliptical guide rail, and the first lower clamping plate moves along the inner elliptical guide rail. A first clamping seat 2133 is fixed on the side of the first lower clamping plate. The first upper clamping plate is rotatably connected to the first clamping seat through a pivot, so that the first upper clamping plate can be rotatably opened relative to the first lower clamping plate. A first spring 2134 is also connected between the first clamping seat and the first upper clamping plate to pull up the first upper clamping plate for the paper tape to pass through. A notch matching the size of the outer elliptical guide rail is opened at the elliptical track corresponding to the lower part of the pressing piece. At this notch, due to the lack of limitation of the outer elliptical guide rail on the first upper clamping plate, under the action of the first spring, the first upper clamping plate is opened unilaterally. At this time, the paper tape is transported between the first upper clamping plate and the first lower clamping plate, and then the pressing piece presses down the first upper clamping plate to complete the clamping of the paper tape. The two ends of the first lower clamping plate are respectively connected to the second chain 216 through the first connecting pins 2137. The second chain forms an elliptical shape through several second sprockets. The second sprockets are driven after being speed-reduced by a motor. Driven by the power of the second chain, the first paper skin clamp that has completed the paper tape clamping operation continues to move forward along the elliptical track. When the first upper clamping plate leaves the notch opened at the elliptical track, after entering the outer elliptical guide rail, the first upper clamping plate is limited to continue clamping and transporting the paper tape. The first upper clamping plate moves along the outer elliptical guide rail through the first outer bearing roller 2131, and the first lower clamping plate moves along the inner elliptical guide rail through the first inner bearing roller 2136. Several equally spaced second rollers 218 are also provided on the frame.A bulge is provided on one side of the elliptical outer guide rail away from the paper cutting mechanism, that is, the horizontal end of the elliptical outer guide rail is designed to be an upwardly inclined bulge. At this time, the distance between the first outer bearing roller and the first lower clamping plate is enlarged, the clamped paper tape is released, and the paper tape conveying operation is completed.

[0046] The working steps of the paper cutting device are as follows: the paper tape of the paper roll is driven by the paper feeding mechanism, passes through the upper blade and the lower blade, and enters the first paper clamp; the third cylinder pulls the pressing plate downward to press the outer bearing rollers on both sides of the upper clamp, so that the upper clamp and the lower clamp bite to clamp the paper tape; the second chain drives the first paper clamp to straighten and pull the paper tape; the first cylinder presses the upper paper roller downward to press the paper tape; the second cylinder moves to make the upper blade descend to cut the paper tape; the third cylinder drives the pressing plate to rise and reset; the second chain drives the first paper clamp to continue to move forward, and when it reaches the protrusion of the outer track, the upper clamp and the lower clamp are separated and reset, so that the paper tape is loosened and placed on the paper bed of the paper cutting device to form packaging paper; the next paper cut will be pulled and cut by the second paper clamp, and the two are carried out alternately, thereby improving the efficiency of paper cutting. Among them, the chain is detected by an encoder for the length of a single paper cut.
