Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging technology, and more specifically to a novel aluminum foil lubrication device. Background Technology

[0002] In the cigarette manufacturing process, the aluminum foil conveying process for the small boxes in the packaging unit is as follows: the aluminum foil is conveyed to the embossing roller using a conveyor roller, where the outer surface of the embossing roller contacts the aluminum foil to imprint the pattern onto the foil, and then it is conveyed to the cutting process. To improve production efficiency, the packaging machine is equipped with two sets of aluminum foil trays, one for normal use and one as a spare.

[0003] Because of the rough surface of aluminum foil, a layer of lubricating oil needs to be applied to its surface to ensure its conveying stability and foldability. Currently, a lubrication device is installed along the aluminum foil conveying path, between the conveyor roller and the embossing roller, to apply lubricating oil to the aluminum foil at that location. The problem is that even stationary spare aluminum foil is constantly in contact with its corresponding lubrication device and is coated with lubricating oil. This prolonged contact causes the oil film on the spare aluminum foil to become excessively thick. Once activated, the aluminum foil with the excessively thick oil film has already softened from being soaked in lubricating oil, easily causing conveyor blockages. In severe cases, this can lead to equipment shutdown, which is detrimental to the control of production quality and efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a novel aluminum foil lubrication device, which is applied in the cigarette production process. Each of the two sets of aluminum foil trays in the packaging machine is equipped with a lubrication device. The lubrication device can be switched to the initial position where lubricating oil does not leak into the aluminum foil or to the working lubrication position. Switching the lubrication device of the spare aluminum foil tray to the initial position can effectively avoid the situation where the oil film on the spare aluminum foil is too thick before use, which affects normal production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel aluminum foil lubrication device, characterized by the following structural features:

[0007] It is used in conjunction with the aluminum foil paper of the packaging machine. The packaging machine is equipped with two sets of aluminum foil paper trays, one for use and one for backup. The aluminum foil paper of each set of aluminum foil paper trays is fed to the embossing roller through the conveyor roller. Each set of aluminum foil paper trays is equipped with a lubrication device. The lubrication device is set downstream of the conveyor roller and upstream of the embossing roller along the conveying path of the aluminum foil paper.

[0008] The lubrication device includes a drive mechanism, a lubrication cylinder, a lubrication roller, and an oil storage assembly. Both the lubrication cylinder and the lubrication roller have hollow inner cavities. The lubrication roller is supported at both ends by bearings and is coaxially built into the lubrication cylinder, allowing it to rotate independently relative to the lubrication cylinder under external force. It can rotate together with the lubrication cylinder, which is driven by the drive mechanism to rotate around the central axis. The lubrication cylinder extends horizontally outside the surface of the aluminum foil facing upwards, and an opening is reserved on the cylinder body. The outer roller surface of the lubrication roller is a felt surface that can be exposed through the opening. The lubrication cylinder can be rotated to the lubrication position or the initial position by the drive mechanism. When in the lubrication position, the opening faces the aluminum foil surface, and the exposed part of the lubrication roller can maintain contact with the aluminum foil along the full width of the aluminum foil. The lubrication roller generates independent rotation relative to the lubrication cylinder by the friction between the outer roller surface and the aluminum foil. When the lubrication cylinder is in the initial position, the opening faces away from the aluminum foil. The oil storage assembly is used to supply oil to the felt surface of the lubrication roller through a lubrication oil circuit with a switch valve.

[0009] The structural features of this utility model also lie in:

[0010] The lubrication roller includes a sleeve shaft and a felt roller. The sleeve shaft is an axially penetrating hollow cylinder, and the felt roller is an axially penetrating hollow cylinder made of felt material. They are coaxially and tightly fitted outside the sleeve shaft. Multiple small holes are evenly distributed on the sleeve shaft in the area overlapping with the felt roller. The ends of both shafts are exposed for mounting bearings. One end of the shaft is detachably sealed with a cap. The inner cavity of the sleeve shaft is used to receive lubricating oil from the oil storage component through the lubrication oil passage. The lubricating oil leaks into the felt roller through the multiple small holes. The lubrication oil passage extends into the inner cavity of the sleeve shaft from the other end of the shaft. The oil outlet is located inside the sleeve shaft and has multiple outlets. The multiple oil outlets are evenly spaced along the axial direction and the entire length of the felt roller.

[0011] The driving device is a rotary cylinder. One end of the lubrication cylinder has a flange and is coaxially assembled with the rotary table of the rotary cylinder through the flange. Two grooves for installing bearings are formed inside the cylinder, and the two shaft ends of the lubrication roller are supported by bearings built into the two grooves.

[0012] The opening on the lubrication cylinder has a fan-shaped cross-section when cut radially along the cylinder body. Its length direction is parallel to the axial direction of the lubrication roller, and its length range covers the entire length of the lubrication roller. The length of the opening is longer than the length of the lubrication roller.

[0013] The oil storage assembly includes an oil storage tank and a lubrication oil circuit. The lubrication oil circuit includes an oil outlet pipe, a lubrication channel, and an oil dripping pipe. An L-shaped channel formed inside the lubrication cylinder serves as the lubrication channel. One end of the channel has an internal thread and is threaded to the externally threaded end of the oil dripping pipe. The other end is connected to the outside and is detachably connected to the oil outlet pipe located outside the lubrication cylinder. The oil outlet pipe has a switch valve and its other end is detachably connected to the oil drain port at the bottom of the oil storage tank. The oil dripping pipe extends coaxially into the inner cavity of the lubrication roller. Multiple oil outlets are provided on the pipe section located in the inner cavity of the lubrication roller. These multiple oil outlets are evenly spaced along the entire length of the lubrication roller felt surface, axially.

[0014] The entire device is installed on the frame of the packaging machine.

[0015] Compared with existing technologies, the beneficial effects of this utility model are reflected in:

[0016] The lubrication device of this invention utilizes a drive mechanism to rotate the lubrication cylinder with a built-in lubrication roller, allowing it to switch between a lubrication position and an initial position. In the initial position, the opening of the lubrication cylinder faces away from the aluminum foil, and the lubrication roller does not contact the aluminum foil. This directly avoids the situation where the spare aluminum foil is in prolonged contact with lubricating oil, resulting in an excessively thick oil film. This eliminates the production risks such as conveying blockage or conveying misalignment caused by this, ensuring that the spare aluminum foil can be smoothly put into use. In the lubrication position, the lubrication roller can maintain contact with the passing aluminum foil through the opening of the lubrication cylinder, and oil is supplied by the oil storage component to achieve lubrication of the aluminum foil, which is beneficial to ensuring production quality and production continuity.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please refer to Figures 1 to 4 The novel aluminum foil lubrication device of this embodiment is used in conjunction with the aluminum foil of the ZB45 packaging machine. The packaging machine is equipped with two sets of aluminum foil trays, one for use and one for backup. The aluminum foil of each set of aluminum foil trays is conveyed to the embossing rollers through the conveyor rollers. The paper surface is in contact with the outer roller surface and is conveyed by the sequential traction of each roller. Each set of aluminum foil trays is equipped with a set of lubrication devices. The lubrication devices are set downstream of the conveyor rollers and upstream of the embossing rollers along the conveying path of the aluminum foil.

[0024] The lubrication device includes a drive mechanism 1, a lubrication cylinder 2, a lubrication roller 3, and an oil storage assembly. Both the lubrication cylinder 2 and the lubrication roller 3 have hollow inner cavities. The lubrication roller 3 is supported at both ends by bearings 4 and is coaxially built into the lubrication cylinder 2, allowing it to rotate independently relative to the lubrication cylinder 2 under external force. It can rotate together with the lubrication cylinder 2, which is driven by the drive mechanism 1 to rotate around the central axis. The lubrication cylinder 2 extends horizontally beyond the surface of the aluminum foil side, and an opening 21 is provided on the cylinder body. The outer roller surface of the lubrication roller 3 is a felt surface, allowing it to pass through the opening 21. 1. The lubrication cylinder 2 is driven by the drive mechanism 1 and can rotate to the lubrication position or the initial position. When it is in the lubrication position, the opening 21 faces the aluminum foil surface. The exposed part of the lubrication roller 3 can maintain contact with the aluminum foil along the full width of the aluminum foil. The lubrication roller 3 generates independent rotation relative to the lubrication cylinder 2 by the friction between the outer roller surface and the aluminum foil. When the lubrication cylinder 2 is in the initial position, the opening 21 faces away from the aluminum foil and upwards. The oil storage assembly is used to supply oil to the felt surface of the lubrication roller 3 through the lubrication oil circuit with the switch valve 53.

[0025] In specific implementation, the corresponding structural configuration of the aforementioned novel aluminum foil lubrication device also includes:

[0026] The lubrication roller 3 includes a sleeve shaft 31 and a felt roller 33. The sleeve shaft 31 is an axially penetrating hollow cylinder, and the felt roller 33 is a felt material, an axially penetrating hollow cylinder. They are coaxially and tightly fitted outside the sleeve shaft 31. Multiple small holes 311 are evenly distributed on the sleeve shaft 31 in the area overlapping with the felt roller 33. The ends of both shafts are exposed for mounting bearings 4. One end of the shaft is detachably sealed by bolts with a cover 32. The inner cavity of the sleeve shaft 31 is used to receive lubricating oil from the oil storage component through the lubrication oil passage. The lubricating oil leaks through the multiple small holes 311 to the felt roller 33. The lubrication oil passage extends into the inner cavity of the sleeve shaft 31 from the other end of the sleeve shaft 31. The oil outlet 551 is located inside the sleeve shaft 31 and has multiple locations. The multiple oil outlets 551 are evenly spaced along the axial direction and the entire length of the felt roller 33.

[0027] The driving device is a rotary cylinder. One end of the lubrication cylinder 2 is fitted with a flange 22 and is coaxially assembled with the rotary table of the rotary cylinder through the flange 22. Two grooves 23 are formed inside the cylinder for installing bearings 4. The two shaft ends of the lubrication roller 3 are supported by bearings 4 built into the two grooves 23.

[0028] The opening 21 on the lubrication cylinder 2 has a fan-shaped cross-section cut radially along the cylinder body. Its length direction is parallel to the axial direction of the lubrication roller 3, and its length range covers the entire length of the lubrication roller 3. The length of the opening is longer than the length of the lubrication roller 3.

[0029] The oil storage assembly includes an oil storage tank 51 and a lubrication oil circuit. The lubrication oil circuit includes an oil outlet pipe 52, a lubrication channel 54, and an oil drip pipe 55. The L-shaped channel formed inside the lubrication cylinder 2 serves as the lubrication channel 54. One end of the channel has an internal thread and is threaded to the end of the oil drip pipe 55, which has an external thread. The other end is connected to the outside and is detachably connected to the oil outlet pipe 52 located outside the lubrication cylinder 2. The oil outlet pipe 52 has a switch valve 53 and is detachably connected to the oil drain port at the bottom of the oil storage tank 51. The oil drip pipe 55 extends coaxially into the inner cavity of the lubrication roller 3. The pipe section located in the inner cavity of the lubrication roller 3 has multiple oil outlets 551. The multiple oil outlets 551 are evenly spaced along the axial direction and along the entire length of the felt surface of the lubrication roller 3. The free end of the oil drip pipe 55 is closed.

[0030] The entire device can be installed on the packaging machine frame, with the lubrication cylinder 2 extending outwards from the aluminum foil at its location. The oil storage tank 51 can be separately mounted on the packaging machine frame using a bracket. The oil outlet pipe 52 is a flexible hose, and its connection to the oil outlet of the oil storage tank 51 and the channel opening of the lubrication channel 54 can be detached via quick couplings. The oil storage tank 51 is equipped with a filler port for adding lubricating oil.

[0031] By configuring one set of the novel aluminum foil lubrication device of this embodiment for each of the two sets of aluminum foil used and spared in the packaging machine, hereinafter referred to as the set of lubrication devices for the aluminum foil currently in production as set A, and the set of lubrication devices for the spare aluminum foil as set B, the following method can be used:

[0032] The lubrication cylinder 2 of the A-group lubrication device is driven by the drive mechanism 1 to rotate to the lubrication position, so that the opening 21 of the lubrication cylinder 2 faces the surface of the aluminum foil paper that is being transported. The aluminum foil paper being transported keeps in contact with the felt surface of the lubrication roller 3 exposed through the opening 21. The lubrication roller 3 rotates around the central axis inside the lubrication cylinder 2 due to the friction between it and the aluminum foil paper. The lubricating oil in the oil storage tank 51 flows through the oil outlet pipe 52-lubrication channel 54-drip pipe 55 in sequence. It drips into the inner cavity of the sleeve shaft 31 of the lubrication roller 3 through the multiple oil outlets 551 of the drip pipe 55, and then seeps into the felt roller 33 through the multiple small holes 311 of the sleeve shaft 31. The lubricating oil is applied to the aluminum foil paper in contact with it through the felt roller 33, so as to achieve the lubrication of the aluminum foil paper before it is sent to the embossing roller.

[0033] The lubrication cylinder 2 of the B-group lubrication device is driven by the drive mechanism 1 to rotate back to the initial position, so that the opening 21 of the lubrication cylinder 2 faces upward away from the aluminum foil. At this time, the switch valve 53 of the oil storage component can remain closed, so that the felt roller 33 does not come into contact with the aluminum foil, thus avoiding the situation where the spare aluminum foil is soaked in lubricating oil for a long time and becomes soft.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
