Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum foil packaging, and in particular relates to a lubricating device for transmitting aluminum foil. Background Art

[0002] As an industrial manufacturing material, aluminum foil is mainly used in packaging protection, daily necessities, construction, etc. The application of aluminum foil in cigarette companies lies in: relying on the development and utilization of cigarette packaging lining (aluminum foil) (mainly printing pictures and texts on aluminum foil) to enhance brand value and obtain a good corporate image, and also in anti-counterfeiting needs. Since then, aluminum foil has entered a new development period in the cigarette industry with rich pictures and texts, colorful, moisture-proof and anti-counterfeiting functions.

[0003] When cigarettes are packed in aluminum foil, the surface of the aluminum foil is relatively dry and the paper is relatively fragile, so it is easy to break when folding. In order to solve the above problems, a lubrication device is often required. Usually, a wool pad assembly is added next to the aluminum foil roller, and lubricating oil is adhered to the wool pad assembly. When the aluminum foil passes between the aluminum foil roller and the wool pad assembly, the lubricating oil in the wool pad assembly is wiped on the aluminum foil to obtain lubrication.

[0004] In the existing lubrication device, the wool pad assembly is pressed on the aluminum foil by its own gravity. When the packaging machine stops, the wool pad assembly does not separate from the aluminum foil. The wool pad contacts the aluminum foil at the same position for a long time, forming excessive oil stains. Moreover, when the wool pad assembly is pressed against the aluminum foil, the aluminum foil cannot be kept in a tensioned state. Utility Model Content

[0005] The purpose of the utility model is to provide a lubrication device for transmitting aluminum foil, by sliding the first slider in the U-shaped groove, the oiling mechanism is turned over and moved up and down, when lubrication is needed, the felt block is pressed against the aluminum foil, when lubrication is not needed, the support block is pressed against the aluminum foil, so as to avoid long-term contact between the felt and the aluminum foil to form excessive oil stains, and also to keep the aluminum foil in a tensioned state.

[0008] It is further defined that the mounting frame is embedded with two magnetic blocks, the two magnetic blocks are symmetrically arranged about the push rod, and the two magnetic blocks are located in the U-shaped groove, and the first slider is an iron block. With such a structural design, through the magnetic attraction between the magnetic blocks and the first slider, when the first slider slides in the arc portion of the U-shaped slide groove, it can pass through one magnetic block under the action of inertia and then be adsorbed together with the other magnetic block, thereby reducing the possibility of the first slider sliding back.

[0009] It is further defined that the mounting frame is provided with a mounting hole, the mounting hole is arranged in the middle of the U-shaped groove and is connected to the U-shaped groove, a spring is connected in the mounting hole, the free end of the spring is connected to an anti-reversal block, both sides of the anti-reversal block close to the end of the first slider are inclined, and the inclined surface is inclined from the inside to the outside in a direction away from the U-shaped groove. With such a structural design, through the cooperation of the anti-reversal block and the spring, when the first slider slides in the arc portion of the U-shaped slide groove, after passing through the anti-reversal block under the action of inertia, it is blocked on the other side of the anti-reversal block when it returns, reducing the possibility of the first slider sliding back.

[0010] It is further defined that the mounting frame is further provided with a limiting hole connected to the mounting hole, and the anti-reversal block is provided with a limiting protrusion, and the limiting protrusion is passed through the limiting hole. Such a structural design further limits the position of the anti-reversal block through the limiting effect of the limiting hole on the limiting protrusion, avoids the part of the anti-reversal block passing through the mounting hole too long, and reduces the possibility of failure of the anti-reversal block.

[0011] It is further defined that the mounting frame is also provided with two straight grooves, and the two straight grooves are symmetrically arranged at the two ends of the mounting frame, and a straight groove close to the U-shaped groove is arranged along the symmetry line of the U-shaped groove, and one end close to the arc portion of the U-shaped groove is located below the center position of the arc portion of the U-shaped groove, and the two straight grooves are slidably connected with second sliders, and the two second sliders are rotatably connected to the two ends of the connecting block.

[0013] It is further defined that the connection between the push rod and the moving frame is located in the middle of the moving frame. Such a structural design, by connecting the push rod in the middle of the moving frame, makes the weight of the left and right sides of the connection between the moving frame and the push rod closer, so that when the push rod is pushed, the forces on both sides are more balanced, and the pushing obstacle caused by the large weight difference between the left and right sides of the connection between the moving frame and the push rod is reduced.

[0014] It is further defined that the fixing mechanism includes an external thread provided on the end of the push rod away from the mounting frame and an internal thread provided in the adjustment hole, and when the felt or the support block is working, the push rod passes through the adjustment hole and is threadedly connected with the adjustment hole.

When the first slider 311 slides in the strip portion of the U-shaped groove 310, the second slider 342 also moves with the connecting block 42. The straight groove 341 and the second slider 342 can limit the position of the oiling mechanism moving up and down, thereby reducing the possibility of the first slider 311 getting stuck in the U-shaped groove 310 and increasing the smoothness of the use of the oiling device.
