[0003] Original invention name: Aluminum roll packaging plastic wrapping production line and working method thereof TECHNICAL FIELD

[0004] The present application relates to an aluminum roll plastic wrapping machine and a working method thereof. BACKGROUND

[0005] The aluminum roll is a metal product processed by a casting and rolling machine after rolling aluminum material and bending angle processing; the aluminum roll is widely used in electronics, packaging, construction, machinery and other aspects,

[0006] The aluminum roll needs to be packaged with plastic wrapping film before delivery. In the past, the plastic wrapping film packaging was transported to the manual packaging station by a crane or a forklift, and then packaged manually and transported out by the crane or the forklift. The transportation of the crane or the forklift is not only not safe, but also has low packaging efficiency and large manual labor. SUMMARY

[0007] The purpose of the present application is to provide an aluminum roll packaging plastic wrapping production line and a working method thereof. The aluminum roll packaging plastic wrapping production line is designed reasonably, which is beneficial to improve the efficiency and safety of packaging.

[0008] The aluminum roll packaging plastic wrapping production line of the present application is characterized by comprising a cross rotating disc rotating intermittently, a first track, a second track and a third track arranged on the side of the cross rotating disc. The cross rotating disc comprises a base and a rotating lifting shaft arranged on the base. A cross shaft is arranged on the upper part of the rotating lifting shaft. The rotating lifting shaft and the cross shaft thereon have four work stations circumferentially spaced 90 degrees. The first track, the second track and the third track are consistent with the directions of the three branch shafts of the cross shaft. The first track and the second track are arranged in the same direction. The third track is perpendicular to the first track or the second track. A roll transporting vehicle sliding along the track is arranged on the first track and the second track. An aluminum roll plastic wrapping machine sliding along the track is arranged on the third track.

[0009] Further, the roll transporting vehicle comprises a frame slidable along the track. Two limiting shafts are arranged on the frame along the length direction of the track. The aluminum roll to be packaged is arranged between the two limiting shafts.

[0010] Furthermore, the aforementioned aluminum coil wrapping machine includes a frame, a packaging bag roll support fixed on the frame, and a suction cup frame on the frame. A packaging bag roll is hinged to the packaging bag roll support. The suction cup frame has several suction cups for adsorbing the opening of the packaging bag near the packaging bag roll support. The bottom of the suction cup frame is provided with pulleys. The frame is provided with a slide rail that cooperates with the pulleys. The direction of the slide rail is perpendicular to the axis of the packaging bag roll.

[0011] Furthermore, the aforementioned packaging bag roll support includes two parallel right-angled triangular frames, which are connected by a connecting rod to form a packaging bag roll support in the form of a right-angled triangular prism. The first right-angled surface of the packaging bag roll support in the right-angled triangular prism is horizontally arranged, and the second right-angled surface is parallel to the suction cup frame. A hinge shaft is provided on one side away from the suction cup frame, and the packaging bag roll is sleeved on the hinge shaft.

[0012] Furthermore, the second right-angled surface of the aforementioned packaging bag roll support is provided with four sets of clamping shafts for clamping film, each set of clamping shafts having two short shafts with their outer peripheries close to each other.

[0013] Furthermore, the aforementioned suction cup frame is a rectangular frame, with suction cups at the four corners of the side closest to the packaging bag roll support. After the packaging bag on the packaging bag roll is output from the hinge shaft, the four corners of the packaging bag are clamped by four pairs of clamping shafts at the top and bottom, respectively. Then, the opening of the packaging bag extends and is adsorbed onto the four suction cups, so that the packaging bag located between the suction cup frame and the packaging bag roll support forms a cylindrical shape.

[0014] Furthermore, the bottom of the aforementioned frame has rollers that slide along a third track.

[0015] The present invention relates to a working method for an aluminum coil packaging and wrapping production line, characterized in that: the aluminum coil packaging and wrapping production line includes an intermittently rotating cross-shaped rotary table, a first track, a second track, and a third track located on the side of the cross-shaped rotary table. The cross-shaped rotary table includes a base and a rotating lifting shaft located on the base. A cross shaft is provided on the upper part of the rotating lifting shaft. The rotating lifting shaft and the cross shaft thereon have four work positions spaced 90 degrees apart on a circumference. The first track, the second track, and the third track are aligned with the three support shafts of the cross shaft. The first track and the second track are arranged in the same direction, and the third track is perpendicular to the first track or the second track. A coil transport trolley is provided on the first track and the second track, and an aluminum coil wrapping machine is provided on the third track, which also slides along the track. During operation, the coil transport trolley on the first track transports the aluminum coil to the cross-shaped rotary table, which receives and rotates it 90 degrees. The aluminum coil wrapping machine then wraps the aluminum coil. Finally, the cross-shaped rotary table rotates it 90 degrees again, and the coil transport trolley located on the second track outputs the aluminum coil.

[0016] The aluminum coil packaging and wrapping production line of the present invention realizes the transfer of aluminum coils through a cross-shaped rotary table and the coil transport vehicles on the first and second tracks, and the wrapping is performed by the aluminum coil wrapping machine on the third track, thereby reducing manual intervention in the wrapping and improving efficiency.

[0024] The method of the present invention will be further described in detail below with reference to embodiments. It should be particularly noted that the scope of protection of the present invention should include, but is not limited to, the technical content disclosed in this embodiment.

[0025] The aluminum coil packaging and wrapping production line of the present invention includes an intermittently rotating cross-shaped rotary disk 1, a first track 2, a second track 3, and a third track 4 disposed on the side of the cross-shaped rotary disk 1. The cross-shaped rotary disk 1 includes a base 5 and a rotating lifting shaft 6 disposed on the base 5. A cross shaft 7 is disposed on the upper part of the rotating lifting shaft 6. The rotating lifting shaft 6 and the cross shaft 7 thereon have four work stations with a circumferential interval of 90 degrees. The first track 2, the second track 3, and the third track 4 are aligned with the three support shafts 9 of the cross shaft 7. The first track 2 and the second track 3 are arranged in the same direction. The third track 4 is perpendicular to the first track 2 or the second track 3. A coil transport vehicle 10 is disposed on the first track 2 and the second track 3 and slides along the track. An aluminum coil wrapping machine A is disposed on the third track 4 and slides along the track. The first track 2, the second track 3, and the third track 4 can be strip tracks with rollers that cooperate with them to roll. The rotating lifting shaft 6 can be driven to rotate by a gear drive mechanism on the base. A hydraulic cylinder is provided below the base to drive the lifting of the base 5 and the cross shaft 7 on it. The cross rotating disk 1 rotates 90 degrees intermittently, which means that the rotating lifting shaft 6 stops after rotating 90 degrees once and waits for the next rotation.

[0026] Furthermore, to facilitate the limiting of the aluminum coil 13 and prevent it from slipping, the aforementioned transport trolley 10 includes a frame 11 that can slide along the track. Two limiting shafts 12 are provided on the frame along the length of the track, and the aluminum coil 13 to be packaged is positioned between the two limiting shafts 12. The limiting shafts 12 can be limiting blocks or the like. The lifting function of the rotating lifting shaft 6 is to allow the aluminum coil to avoid the limiting shafts. If no limiting shafts are used, the transfer process can be achieved using a liftable transport trolley.

[0027] Furthermore, for rational design, the aforementioned aluminum coil wrapping machine A includes a frame A1, a packaging bag roll support A2 fixed on the frame, and a suction cup frame A3 on the frame. A packaging bag roll A4 is hinged to the packaging bag roll support A2. The suction cup frame has several suction cups A5 for adsorbing the opening of the packaging bag near the packaging bag roll support. A pulley A6 is provided at the bottom of the suction cup frame. A slide rail A7 that cooperates with the pulley A6 is provided on the frame A1. The direction of the slide rail A7 is perpendicular to the axis of the packaging bag roll A4.

[0028] Furthermore, the aforementioned packaging bag roll support A2 includes two parallel right-angled triangular frames A8, which are connected by a connecting rod A9 to form a packaging bag roll support in the form of a right-angled triangular prism. The first right-angled surface of the packaging bag roll support in the right-angled triangular prism is horizontally arranged, and the second right-angled surface is parallel to the suction cup frame. A hinge shaft A10 is provided on one side away from the suction cup frame, and the packaging bag roll A4 is sleeved on the hinge shaft A10.

[0029] Furthermore, the packaging bag roll support A2 is provided with four sets of clamping shafts A11 for clamping film at the second right-angled surface. Each set of clamping shafts A11 has two short shafts A12 with their outer peripheries close to each other. These short shafts A12 are rotatable optical shafts, which can reduce friction.

[0030] The suction cup frame A3 is a rectangular frame, with suction cups A5 at each of its four corners on the side closest to the packaging bag roll support. After the packaging bag P on the packaging bag roll is output from the hinge shaft, the four corners of the packaging bag are clamped by four pairs of clamping shafts A11 (top and bottom). Then, the opening of the packaging bag extends and is adsorbed onto the four suction cups A5, so that the packaging bag between the suction cup frame and the packaging bag roll support forms a cylindrical shape. The suction cups A5 are connected to a negative pressure pump so that the packaging bag is adsorbed under negative pressure.

[0031] Furthermore, for the sake of rational design, the bottom of the aforementioned frame has rollers A13 that slide along the third track.

[0032] When the aluminum coil wrapping machine A is working, the packaging bag roll opening is first pulled out manually. After the packaging bag on the roll is output from the hinge shaft, the four corners of the packaging bag are clamped by four pairs of clamping shafts A11, one above and one below. Then, the opening of the packaging bag extends and is respectively attracted to four suction cups A5, so that the packaging bag between the suction cup frame and the packaging bag roll support forms a cylindrical shape. Afterwards or simultaneously, the entire frame A1 slides along the third track closer to the cross rotating disk 1. The aluminum coil hanging on the support shaft of the cross rotating disk 1 gradually enters into the cylindrical packaging bag, and then passes through the second right angle. The cutter A14 on the side cuts the packaging bag vertically along the third track, and at the same time, the suction cup A5 no longer adheres to the packaging bag. At this point, the packaging bag is completely wrapped around the aluminum coil. Then, the frame A1 slides away from the cross rotating disk 1 along the third track. The cross rotating disk 1 rotates 90 degrees and reaches the position of the third track. The coil transport carriage 10 on the third track approaches the cross rotating disk 1. The aluminum coil with the packaging bag on the cross rotating disk 1 descends onto the coil transport carriage 10. The coil transport carriage 10 moves away from the cross rotating disk 1 along the third track, thus completing the entire wrapping process of the aluminum coil.

[0033] The present invention discloses a working method for an aluminum coil packaging and wrapping production line. The production line includes an intermittently rotating cross-shaped rotary table, a first track, a second track, and a third track located on the side of the rotary table. The rotary table includes a base and a rotating lifting shaft mounted on the base. A cross shaft is located on the upper part of the rotating lifting shaft. The rotating lifting shaft and the cross shaft have four circumferentially spaced 90-degree workstations. The first, second, and third tracks are aligned with the three support axes of the cross shaft. The first and second tracks are arranged in the same direction, and the third track is perpendicular to either the first or second track. A coil transport trolley is mounted on the first and second tracks, sliding along the tracks. An aluminum coil wrapping machine is mounted on the third track, sliding along the track. During operation, the coil transport trolley on the first track transports the aluminum coil to the rotary table, which receives it and rotates it 90 degrees. The aluminum coil wrapping machine then wraps the aluminum coil. Finally, the rotary table rotates another 90 degrees, and the coil transport trolley located on the second track outputs the aluminum coil.

[0034] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be included in the scope of the present invention.
