Description

Technical Field

[0001] This utility model relates to the field of stretch wrapping machine technology, specifically a stretch wrapping machine for cans. Background Technology

[0002] A can wrapping machine is an automated device specifically designed for wrapping cylindrical cans.

[0003] In existing can wrapping machines, the cans to be packaged are typically placed on a rotating base, and one end of the film is fixed to one side of the rotating base. The base is then rotated to rotate the can, causing the film to wrap around the outside of the can. However, when the rotation speed exceeds a critical value, the centrifugal force on the can causes its center of gravity to gradually deviate from the axis of rotation. Since the existing equipment relies only on the base for support and lacks an upper fixing device, this imbalance will continue to amplify, eventually causing the can to tip over. This phenomenon is particularly pronounced for slender cans with a large height-to-diameter ratio.

[0004] Therefore, a wrapping machine for cans is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a wrapping machine for cans to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A wrapping machine for cans includes a base, a mounting frame welded to one side of the top of the base, a second threaded rod mounted inside the mounting frame via a bearing, a threaded hole slider sleeved on the outer side of the second threaded rod, one end of the threaded hole slider slidingly extending out of the mounting frame, a film release assembly fixed to one end of the threaded hole slider, a support frame fixed to the top of the mounting frame by bolts, a second motor fixed to the top of the support frame by bolts, a cylinder fixed to one side of the top of the support frame by bolts, the output end of the cylinder extending through and out of the support frame and fixed to a fixing plate, a rotating pressure plate mounted to the bottom of the fixing plate via a rotating seat, a support slide rod fixed to each side of the top of the fixing plate by bolts, one end of the support slide rod slidingly penetrating the interior of the support frame, a support seat assembly rotatably mounted to one side of the top of the base, a film clamping assembly provided on one side of the support seat assembly, and a first motor fixed to the bottom of the base by bolts.

[0006] Preferably, the output end of the second motor passes through the inside of the support frame and extends into the inside of the mounting frame, and is fixedly connected to the top end of the second threaded rod, and the threaded hole slider and the second threaded rod are connected by thread engagement.

[0007] Preferably, the top of the base is provided with an annular groove, and a support slider is welded to each side of the bottom of the support assembly, and the two support sliders are slidably installed inside the annular groove.

[0008] Preferably, the film release assembly includes a base frame, and a movable frame is slidably installed inside the base frame. One end of the movable frame is provided with a collar, a film roll is rotatably installed on one side of the base frame, a roller is rotatably installed inside the collar, two limiting holes are opened on one side of the base frame, and an elastic limiting bolt is installed on one side of the movable frame.

[0009] Preferably, the film clamping assembly includes a fixed base, and a limiting groove is formed inside the fixed base, the limiting groove extending through the interior of the fixed base, and a first threaded rod is threadedly connected to one side of the fixed base.

[0010] Preferably, one end of the first threaded rod is rotatably mounted with an anti-slip pressure plate, and the anti-slip pressure plate is located inside the limiting groove. A second handwheel is mounted on one end of the first threaded rod.

[0011] Preferably, the support assembly includes a rotating seat, and the rotating seat has an internal mounting groove, in which a double-threaded screw is mounted via a bearing.

[0012] Preferably, a threaded slider clamp is respectively fitted on the outer side of both ends of the double-threaded screw, and a first handwheel is rotatably installed on one side of the rotating seat.

[0013] Compared with the prior art, this utility model provides a can wrapping machine with the following advantages:

[0014] When wrapping the can, the can to be wrapped is placed on top of the support assembly. Then, by extending the output end of the control cylinder, the fixed plate is moved downward. As the fixed plate continues to move downward, the bottom of the rotating pressure plate will eventually press against the top of the can. Then, the rotation of the output end of the first motor will drive the support assembly and the can placed on top to rotate. When the can rotates, the friction between the top of the can and the bottom of the rotating pressure plate will cause the rotating pressure plate to rotate at the bottom of the fixed plate, thereby limiting and fixing the top of the can, preventing the can from tipping over during rotation, and ensuring operational safety.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: A mounting bracket 15 is welded to one side of the top of the base 1. A second threaded rod 13 is mounted inside the mounting bracket 15 via a bearing. A threaded hole slider 16 is sleeved on the outside of the second threaded rod 13. One end of the threaded hole slider 16 extends slidably out of the mounting bracket 15. A membrane release assembly 14 is fixed to one end of the threaded hole slider 16. A support frame 12 is fixed to the top of the mounting bracket 15 by bolts. A second motor 11 is fixed to the top of the support frame 12 by bolts. A cylinder 10 is fixed to one side of the top of the support frame 12 by bolts. The output end of the cylinder 10 extends through the support frame 12 and is fixed to a fixing plate 8. A rotating pressure plate 7 is mounted on the bottom of the fixing plate 8 via a rotating seat. A support slide rod 9 is fixed to each side of the top of the fixing plate 8 by bolts. One end of the support slide rod 9 slides through the support frame 12. A support seat assembly 5 is rotatably mounted on one side of the top of the base 1. A membrane clamping assembly 6 is provided on one side of the support seat assembly 5. A first motor 3 is fixed to the bottom of the base 1 by bolts.

[0022] Specifically, such as Figure 1 As shown, when wrapping the can, the can to be packaged is placed above the support assembly 5. Then, the extension of the output end of the control cylinder 10 drives the fixing plate 8 to move downward. Since the bottom of the fixing plate 8 is equipped with a rotating pressure plate 7 through a rotating seat, as the fixing plate 8 continues to move downward, the bottom of the rotating pressure plate 7 will eventually press against the top of the can. Then, the rotation of the output end of the first motor 3 drives the support assembly 5 and the can placed above to rotate. When the can rotates, the friction between the top of the can and the bottom of the rotating pressure plate 7 will cause the rotating pressure plate 7 to rotate at the bottom of the fixing plate 8, thereby limiting and fixing the top of the can, preventing the can from tipping over during rotation, and ensuring operational safety.

[0023] Example 2: The output end of the second motor 11 passes through the inside of the support frame 12 and extends into the inside of the mounting frame 15, and is fixedly connected to the top end of the second threaded rod 13. The threaded hole slider 16 is connected to the second threaded rod 13 by threaded engagement. The top of the base 1 is provided with an annular groove 2, and a support slider 4 is welded to each side of the bottom of the support base assembly 5. The two support sliders 4 are slidably installed inside the annular groove 2. The film release assembly 14 includes a base frame 1401, and a movable frame 1404 is slidably installed inside the base frame 1401. One end of the movable frame 1404 is provided with a collar 1405. A film roll 1407 is rotatably installed on one side of the base frame 1401. A roller 1406 is rotatably installed inside the collar 1405. Two limiting holes 1403 are provided on one side of the base frame 1401, and an elastic limiting bolt 1402 is installed on one side of the movable frame 1404. Film clamping assembly 6 The system includes a fixed base 601, with a limiting groove 602 inside the fixed base 601. The limiting groove 602 extends through the interior of the fixed base 601. A first threaded rod 604 is threadedly connected to one side of the fixed base 601. An anti-slip pressure plate 603 is rotatably mounted on one end of the first threaded rod 604, and the anti-slip pressure plate 603 is located inside the limiting groove 602. A second handwheel 605 is mounted on one end of the first threaded rod 604. The support assembly 5 includes a rotating seat 501, with an installation groove 502 inside the rotating seat 501. A double-threaded screw 504 is mounted inside the installation groove 502 via bearings. A threaded slider clamp 503 is respectively fitted on the outer side of both ends of the double-threaded screw 504. A first handwheel 505 is rotatably mounted on one side of the rotating seat 501. The output end of the first handwheel 505 extends into the installation groove 502 and is fixedly connected to one end of the double-threaded screw 504.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in use, the film roll 1407 is fixed between the movable frames 1404. By pressing the elastic limit bolt 1402, the elastic limit bolt 1402 is moved into the upper limit hole 1403, thereby increasing the distance between the movable frames 1404. Then, the film roll 1407 is placed between the two movable frames 1404, and the roller 1406 is rolled between the two collars 1405. Then, the elastic limit bolt 1402 is moved into the lower limit hole 1403 to clamp the film roll 1407 and the roller 1406. Then, one end of the film is wrapped around the roller 1406 and fixed inside the limit groove 602. By rotating the second handwheel 605, the anti-slip pressure plate 603 is driven to tightly hold one end of the film. Clamped inside the limiting groove 602, the film clamping assembly 6 can be moved by the rotation of the rotating seat 501, thereby stretching and winding the film around the outside of the can. The first handwheel 505 is rotated to drive the double threaded screw 504 to rotate. The rotation of the double threaded screw 504 can drive the two threaded slider clamps 503 to move relative to each other above the rotating seat 501, thereby limiting and clamping the bottom sides of the can placed on the top of the rotating seat 501. During winding, the rotation of the output end of the second motor 11 drives the second threaded rod 13 to rotate. The rotation of the second threaded rod 13 can drive the film release assembly 14 to move along the installation direction of the second threaded rod 13, thereby driving the film to be evenly wound around the outside of the can.

[0025] Working principle: In use, the roller 1406 and the film roll 1407 are rolled and installed between the movable frame 1404. Then, one end of the film is wrapped around the roller 1406 and fixed inside the limiting groove 602. By rotating the second handwheel 605, the anti-slip pressure plate 603 is driven to tightly clamp one end of the film inside the limiting groove 602. Then, the can to be packaged is placed on top of the rotating seat 501. By rotating the first handwheel 505, the two threaded slider clamps 503 move relative to each other above the rotating seat 501, thereby limiting and clamping the bottom sides of the can placed on top of the rotating seat 501. By controlling the extension of the output end of the cylinder 10, the fixing plate 8 is moved downward. As the fixing plate 8 continues to move downward... The rotation will eventually cause the bottom of the rotating pressure plate 7 to press against the top of the tank, thereby limiting and fixing the top of the tank and preventing the tank from tipping over during rotation. Then, the rotation of the output end of the first motor 3 drives the support assembly 5 and the tank placed on top to rotate. The rotation of the rotating seat 501 can drive the film clamping assembly 6 to move accordingly, thereby stretching and wrapping the film around the outside of the tank. During wrapping, the rotation of the output end of the second motor 11 drives the second threaded rod 13 to rotate. The rotation of the second threaded rod 13 can drive the film release assembly 14 to move along the installation direction of the second threaded rod 13, thereby driving the film to be evenly wrapped around the outside of the tank.
