Description

Technical Field

[0001] The present application relates to the technical field of grinding equipment, and in particular to a clamping device for a sealing machine. Background Art

[0002] Existing cosmetics need to be sealed after being canned, usually by tin foil. When sealing, several cosmetic containers are usually grouped together, and the entire group of containers is grabbed by a clamping device and placed in a mold, and then sealed. Then the entire group of containers is clamped and placed on an assembly line.

[0003] However, when changing different molds, the clamping device needs to be replaced simultaneously, which is a complicated process and results in low efficiency. Utility Model Content

[0004] In order to improve efficiency, the present application provides a clamping device for a sealing machine.

[0005] The present application provides a clamping device for a sealing machine using the following technical solution:

[0006] A clamping device for a sealing machine comprises a mounting frame, a plurality of first connecting plates and a suction cup arranged on the first connecting plate, the mounting frame is provided with a threaded rod, the plurality of first connecting plates are distributed in a circular array around the axis of the threaded rod, a first through hole is opened at one end of the first connecting plate, the threaded rod is penetrated through the first through holes of the plurality of first connecting plates, the threaded rod is threadedly connected with a bolt, and the suction cup is arranged at one end of the first connecting plate away from the first through hole.

[0007] By adopting the above technical solution, the suction cup is arranged on the first connecting plate, and the first connecting plate is installed on the mounting frame through the threaded rod and bolts. When replacing different molds, the number of first connecting plates can be increased or decreased according to the number of containers placed in the mold, and several first connecting plates are distributed in a circular array around the axis direction of the threaded rod, and then the first connecting plate is fixed by bolts, thereby reducing the tedious steps of replacement and improving efficiency.

[0008] Optionally, a first elastic pad is provided between two adjacent first connecting plates, and the first elastic pad is coaxially sleeved on the threaded rod.

[0009] By adopting the above technical solution, a first elastic pad is provided, which can provide a larger friction force to the side of the first connecting plate, thereby reducing the possibility of the first rotating plate rotating when fixed, so as to limit the rotation of the first rotating plate.

[0010] Optionally, both end surfaces of the first elastic pad are provided with first tooth surfaces, and the first connecting plate is provided with second tooth surfaces matched with the first tooth surfaces.

[0011] By adopting the above technical solution and by adapting the first tooth surface to the second tooth surface, the stability of the rotation limit of the first rotating plate is improved.

[0012] Optionally, a second connecting plate is provided at one end of the first connecting plate away from the threaded rod, the second connecting plate is slidably connected to the second connecting plate along the vertical direction, the first connecting plate is provided with a limiting member for limiting the second connecting plate, and the suction cup is provided on the second connecting plate.

[0013] By adopting the above technical solution, since one end of the first connecting plate is sequentially passed through the threaded rod, the lower surface of the first connecting plate is uneven, resulting in the adsorption surface installed on the first connecting plate being uneven. Therefore, a second connecting plate is arranged on the first connecting plate, and the second connecting plate can slide vertically so that each suction cup can be leveled.

[0014] Optionally, both ends of the connecting plate are fixedly connected with a sliding rod, the first connecting plate is provided with a second penetration hole for the sliding rod to penetrate, the limiting member is a clamping plate, and a plurality of the clamping plates are provided, and the plurality of the clamping plates are distributed in a circular array around the axis of the second penetration hole, and the first connecting plate is provided with a driving component for driving the clamping plate to clamp the sliding rod.

[0015] By adopting the above technical solution, when leveling a plurality of suction cups, the second connecting plate is slid, and after the second connecting plate is slid to a corresponding position, the driving component drives the clamping plate to clamp the sliding rod, thereby fixing the position of the second connecting plate.

[0016] Optionally, the driving assembly includes a threaded plate, a threaded sleeve and a driving rod, wherein a plurality of threaded plates are provided, and the plurality of threaded plates are distributed in a circular array around the axial direction of the second through hole, and a gap is provided between two adjacent threaded plates. The clamping plate is located on the inner side of the threaded plate, and the threaded sleeve is threadedly connected to the plurality of threaded plates. One end of the driving rod is fixed to the outer side surface of the clamping plate and is provided between two adjacent threaded plates. The threaded sleeve has a first wedge surface, and the driving rod has a second wedge surface matching the first wedge surface.

[0017] By adopting the above technical solution, when the sliding rod is clamped, the threaded sleeve is rotated, and the threaded sleeve forces the driving rod to drive the clamping plate to move in a direction approaching each other through the cooperation of the first wedge surface and the second wedge surface, thereby clamping the sliding rod.

[0018] Optionally, a second elastic pad is provided on the inner side of the clamping sheet.

[0019] By adopting the above technical solution, a second elastic pad is provided, thereby improving the limiting stability of the sliding rod.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The suction cup is arranged on the first connecting plate, and the first connecting plate is installed on the mounting frame through the threaded rod and bolts. When replacing different molds, the number of the first connecting plates can be increased or decreased according to the number of containers placed in the mold, and several first connecting plates are arranged in a circular array around the axis direction of the threaded rod, and then the first connecting plates are fixed by bolts, thereby reducing the cumbersome steps of replacement and improving efficiency;

[0022] 2. When the sliding rod is clamped, the threaded sleeve is rotated. The threaded sleeve forces the driving rod to drive the clamping piece to move in a direction close to each other through the cooperation of the first wedge surface and the second wedge surface, thereby clamping the sliding rod.
