Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum foil rewinding, and specifically relates to an aluminum foil rewinder for packaging. Background Art

[0002] Aluminum foil is a hot stamping material directly rolled into thin sheets from metallic aluminum, and its hot stamping effect is similar to that of pure silver foil. A rewinder is a special equipment for paper, mica tape, and film, and its purpose is to rewind aluminum foil sequentially.

[0003] In the prior art, an aluminum foil rewinder generally consists of a bottom plate, a fixed mounting seat, a rotating shaft, a motor, and a spool. The motor rotates to drive the spool to rotate, and the aluminum foil paper is output through the gap between two groups of rotating shafts, thereby completing the rewinding operation of the aluminum foil roll.

[0004] In the current existing aluminum foil rewinding technology, when rewinding aluminum foil, wrinkles often occur when the end of the aluminum foil paper enters two groups of winding sponge shafts. This requires stopping the machine for adjustment, affecting the rewinding efficiency. And usually, after the aluminum foil rewinding is completed, it is rather troublesome to disassemble the aluminum foil roll. Therefore, an aluminum foil rewinder for packaging is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and address the problems existing in the existing equipment, the utility model proposes an aluminum foil rewinder for packaging.

The bottom of the bracket is installed with a bottom plate, and four notches are opened at the edge of the bottom plate. The bracket is installed inside the notches. A front baffle is installed in front of the bracket, and a support rod is installed on the surface of the front baffle. The support rods are symmetrically installed on both side edges of the front baffle. A rotating shaft is installed in the middle of the two groups of support rods. Sponge sleeves are sleeved on the circumferential surfaces of the two groups of rotating shafts. An axle support is installed on the surface of the bracket. The two support lengths of the axle support are different, and the bottom of the axle support is connected to the bracket by screws. A main rotating shaft is installed in the middle of the two groups of axle supports. Bearing plates are installed at both ends of the main rotating shaft. Bearings are assembled on the inner walls of the two groups of bearing plates. A cross bar is installed on the circumferential surface of the main rotating shaft. The bearings are assembled on the circumferential surface of the main rotating shaft. The front two groups of rotating shafts flatten the aluminum foil paper to reduce wrinkles of the aluminum foil paper.

[0007] Preferably, a winding roller is sleeved on the surface of the main rotating shaft, and an aluminum foil roll is assembled on the circumferential surface of the winding roller. The aluminum foil paper is wound around the surface of the winding roller during the winding process.

[0008] Preferably, a support plate is installed at the top of the bracket. Two sets of notches are formed at the top of the support plate. Two grinding rollers are rotatably installed in the two sets of notches of the support plate. The winding operation of the aluminum foil paper is completed by the rotation of the two grinding rollers.

[0009] Preferably, the two grinding rollers penetrate through the support plate and are rotatably installed. A bearing is sleeved on the contact surface between the grinding roller and the support plate. A sponge sleeve is sleeved on the surface of the grinding roller. The aluminum foil paper passes through the gap between the two grinding rollers, and the sponge sleeve on the surface plays a protective role on the aluminum foil paper.

[0010] Preferably, two bolts are installed at the top of the support plate. Springs are installed on the circumferential surfaces of the two bolts. By rotating the bolts at the top, the distance between the two grinding rollers is adjusted.

[0011] Preferably, a fixing plate is installed on one side of the bracket. A motor support is assembled on the surface of the fixing plate. The motor is installed on the motor support. A first gear is installed at the output end of the motor. The second gear is connected to the first gear by a chain.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The present utility model provides an aluminum foil rewinder for packaging. In order to solve the problem that when the end of the aluminum foil paper enters the two winding sponge shafts during aluminum foil rewinding, wrinkles often occur, which requires stopping the machine for adjustment and affecting the rewinding efficiency. By adding two rotating shafts sleeved with sponge sleeves in front of the winding cylinder, the surface is adjusted once before the aluminum foil paper is rewound, reducing the wrinkles on the surface of the aluminum foil paper and improving the rewinding efficiency. Moreover, it is rather troublesome to disassemble the aluminum foil roll after rewinding. By changing the shaft support to an open style and making the rear strut shorter, it is more labor-saving during disassembly. After rewinding, it can be directly taken down from above, improving the working efficiency of the rewinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] During operation, in the currently existing aluminum foil rewinding technology, when the aluminum foil is rewound and the end of the aluminum foil paper enters between two sets of winding sponge shafts, wrinkles often occur, which requires stopping the machine for adjustment, affecting the rewinding efficiency. And usually, after the aluminum foil rewinding is completed, it is rather troublesome to disassemble the aluminum foil roll 7. Therefore, in view of the above problems, a kind of aluminum foil rewinder for packaging is proposed. During the aluminum foil paper rewinding operation, the aluminum foil paper passes through the gap between two sets of rotating shafts 5 to adjust the surface of the aluminum foil paper. The rotation of the output end of the motor 11 drives the first gear 17 to rotate synchronously. The second gear 16 rotates synchronously with the first gear 17 through the chain 15. A protective housing 12 is assembled around the first gear 17 and the second gear 16.

[0024] Furthermore, a winding roller 24 is sleeved on the surface of the winding roller 24. An aluminum foil roll 7 is assembled on the circumferential surface of the winding roller 24. A support plate 22 is installed at the top of the bracket 1. Two sets of notches are formed at the top of the support plate 22. Two grinding rollers 21 are rotatably installed in the two sets of notches of the support plate 22. The two grinding rollers 21 penetrate through the support plate 22 and are rotatably installed. A bearing 13 is sleeved on the contact surface between the grinding roller 21 and the support plate 22. A sponge sleeve 6 is sleeved on the surface of the grinding roller 21.

[0028] Working principle: In the existing aluminum foil rewinding technology, when aluminum foil is rewound, wrinkles often occur when the end of the aluminum foil paper enters the two sets of rewinding sponge shafts. This requires stopping the machine for adjustment, which affects the rewinding efficiency. And usually, after the aluminum foil rewinding is completed, it is rather troublesome to disassemble the aluminum foil roll 7. Therefore, in view of the above problems, a kind of aluminum foil rewinder for packaging is proposed. During the aluminum foil paper rewinding operation, the aluminum foil paper passes through the gap between the two sets of rotating shafts 5 to adjust the surface of the aluminum foil paper. The rotation of the output end of the motor 11 drives the first gear 17 to rotate synchronously. The second gear 16 rotates synchronously with the first gear 17 through the chain 15. A protective housing 12 is assembled around the first gear 17 and the second gear 16.

[0029] The rotation of the second gear 16 drives the grinding rollers 21 to rotate synchronously. By rotating the two sets of bolts 23, the distance between the two sets of grinding rollers 21 can be adjusted. Springs 20 are installed on the surface of the bolts 23 for buffering. The rotation of the two sets of grinding rollers 21 drives the main rotating shaft 9 to rotate synchronously. A rewinding roller 24 is sleeved on the surface of the main rotating shaft 9.
