Abstract
Description
Technical Field
[0001] The invention relates to the technical field of shaft balance, and in particular to a shaft balance testing device and method for tobacco packaging liner paper aluminum foil composite equipment. Background Art
[0002] After working for a long time, the two shafts that fix the liner paper and the aluminum foil are prone to wear and tear between the bearings, resulting in imbalance such as offset, which makes it impossible for the liner paper fixed on the two shafts to align with the sides of the aluminum foil, reducing the composite quality of the liner paper and the aluminum foil. Existing devices are often equipped with shaft balance monitors and hydraulic centering systems, so that they can detect whether the shaft is unbalanced in real time and accurately correct the shaft.
[0003] However, when the lining paper and aluminum foil of tobacco packaging are laminated, the machine usually operates for a long time without stopping. This causes some electronic balance detection equipment to occasionally fail due to fatigue. If the shaft imbalance problem occurs at this time, it will not be detected in time.
[0004] Also, because the paper base and aluminum foil on the unwinding shaft are generally long, the one-time unwinding and laminating work time is long, and the existing centering system often needs to be stopped after the unwinding is completed to perform the correction operation. This leads to the problem of shaft imbalance at the beginning of the unwinding and laminating operation. Then, the subsequent composite paper base and aluminum foil will have a large range of misalignment area, which will lead to an increase in the subsequent cutting area and cause a large amount of raw material waste.

A gluing mechanism is also provided between the two side plates, and the gluing mechanism includes a coating roller rotatably installed between the two side plates, and also includes a glue liquid hopper for supplying material to the coating roller.
[0016] The shaft balance test method of the tobacco packaging liner paper aluminum foil composite equipment includes the following steps:
[0017] S1: The paper base and the aluminum foil are respectively unwound by the first unwinding roller and the second unwinding roller, and the paper base contacts the coating roller for gluing. The glued paper base and the aluminum foil enter between two hot pressing rollers for extrusion so that the paper base and the aluminum foil are compounded;
[0018] S2: When the installation shaft is unbalanced, the installation shaft will drive the first cam and the first bearing to deviate, causing them to move and change their positions. The rotation of the installation shaft drives the first cam to rotate and hit the force-bearing shaft, and the reminder bell in the force-bearing shaft makes a sound to remind the staff. The force-bearing shaft is forced to drop and squeeze the piston through the push rod. The oil in the oil cylinder is forced to squeeze out the extrusion rod, and the extrusion rod pushes the second section seat to move. The second section seat will contact the first section seat and push up the first section seat, so that the first bearing is pushed up and drives the installation shaft to be adjusted and corrected in the first time without stopping.
[0019] S3: When the installation shaft of the first unwinding roller becomes unbalanced, the installation shaft will drive the second bearing to deviate, causing it to move and change its position. The second bearing will drive the force rod to move, and the force rod will drive the second cam to rotate and squeeze one end of the reciprocating threaded rod. The movement of the force rod will drive the auxiliary rod to move, and the movement of the auxiliary rod will drive the third cam to squeeze the other end of the reciprocating threaded rod. The position of the reciprocating threaded rod will drop, so that the threaded disk will contact the glued paper base. As the paper base moves, the friction force generated by the two will drive the threaded disk to rotate. The rotation of the threaded disk will reciprocate on the reciprocating threaded rod, so that the uneven glue at the edge of the offset paper base is evenly coated by the threaded disk.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. This scheme uses the setting of automatic testing and correction mechanism, so that if an imbalance problem occurs during the operation of the unwinding shaft and the electronic balance detection equipment fails due to fatigue, the installation shaft will drive the first cam and the first bearing to deviate, causing them to move and change their positions. The rotation of the installation shaft drives the first cam to rotate and hit the force-bearing shaft, and the reminder bell in the force-bearing shaft makes a sound to remind the staff, thereby ensuring that the bottoming effect can be achieved in any state.
[0022] 2. When an unbalanced problem occurs during the reel operation, the installation axis can be adjusted and corrected to a certain extent at the first time without stopping the operation, preventing the problem of large-area misalignment in subsequent operations, so that even if subsequent cutting is performed, the waste of raw materials can be reduced and the loss can be reduced. Moreover, the operation of the device can detect the unbalanced problem of the axis at the first time when the electronic balance detection device fails. Therefore, this device can detect and correct the axis under any conditions, and also has the effect of supporting the bottom when the electronic equipment fails.
[0023] 3. This scheme adopts the setting of the glue spreading device. When the offset side paper base has the problem of uneven glue coating, the two ends of the reciprocating threaded rod can be moved downward by offsetting the mounting shaft, so that the threaded disk contacts the paper base. The threaded disk rotates as the paper base moves through the friction between the two. The threaded disk will reciprocate on the reciprocating threaded rod, so that the uneven glue at the edge of the offset paper base is evenly coated, thereby reducing the generation of bubbles during subsequent compounding and avoiding unnecessary waste.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The automatic testing and correction mechanism 5 includes an installation box 51 fixedly mounted on the side plate 4, a force-bearing shaft 52 mounted in the installation box 51, and a first cam 53 fixedly mounted on the installation shaft 3 for pushing the force-bearing shaft 52 to move. When the installation shaft 3 deviates toward the installation box 51, the force-bearing shaft 52 moves, and a reminder bell 900 provided inside the force-bearing shaft 52 makes a sound. A cylinder 54 is provided at the bottom of the installation box 51. When the force-bearing shaft 52 moves, an extrusion rod 56 in the cylinder 54 is squeezed out. The automatic testing and correction mechanism 5 also includes a correction component 57 for pulling the installation shaft 3 for adjustment when the installation shaft 3 deviates. The correction component 57 operates when the extrusion rod 56 is squeezed out.
[0037] The glue spreading device 6 includes a second bearing 61 installed on the mounting shaft 3, a frame 63 fixedly installed on the side plate 4, and a reciprocating threaded rod 64 that can be moved downward is provided in the frame 63, a threaded disk 65 for spreading glue is threadedly installed on the reciprocating threaded rod 64, and bristles 651 are provided on the surface of the threaded disk 65, and a pushing component 62 for pushing the two ends of the reciprocating threaded rod 64 to move downward is installed between the second bearing 61 and the frame 63.
[0038] like Figure 7 and Figure 8 As shown, the interior of the force-bearing shaft 52 is a cavity 700, and the reminder bell 900 is located in the cavity 700. There are also horn-shaped sound amplification cavities 800 on both sides of the force-bearing shaft 52. The force-bearing shaft 52 is installed in the installation box 51 through an assembly component 58. The assembly component 58 includes assembly blocks 581 respectively located at both ends of the force-bearing shaft 52. A rod 600 is fixed in the force-bearing shaft 52. The two ends of the rod 600 are respectively fixedly connected to the assembly blocks 581 on both sides. It also includes an assembly slot 582 opened in the installation box 51, and the assembly block 581 is slidably installed in the assembly slot 582.
[0039] The first cam 53 rotates and squeezes the force-bearing shaft 52 , causing the reminder bell 900 to make a sound, which can amplify the sound through the horn-shaped sound amplification cavity 800 , causing the force-bearing shaft 52 to move downward under force, and the assembly slot 582 will move in the assembly block 581 .
[0040] Specifically, the oil cylinder 54 is provided with a piston 59, and a push rod 583 is fixedly installed at the bottom of the force-bearing shaft 52, and the push rod 583 is located above the piston 59. A seal located in the oil cylinder 54 is provided at the piston 59, and the seal includes a sealing ring and a dust ring (not shown in the figure). A guide member 55 is provided in the oil cylinder 54, and an extrusion rod 56 is installed in the guide member 55. The guide member 55 includes a flange and a guide sleeve, and the extrusion rod 56 is located in the guide sleeve.
[0041] When the force bearing shaft 52 moves downward, the push rod 583 is driven to move downward, so that the push rod 583 pushes the piston 59 to squeeze the oil in the oil cylinder 54, so that the extrusion rod 56 is extruded.
[0042] It should be noted that, in this embodiment, the correction component 57 includes a movable frame 574 fixed to one side of the installation box 51, and also includes a second cut surface seat 573 slidably installed in the movable frame 574, one end of the extrusion rod 56 is in contact with the second cut surface seat 573, and the correction component 57 also includes a first bearing 571 installed on the installation shaft 3, and a first cut surface seat 572 fixedly connected to the first bearing 571 and adapted to the second cut surface seat 573.
[0043] When this end of the installation shaft 3 deviates, it will tilt downward. At this time, the extrusion rod 56 is extruded, so that the second cut surface seat 573 can be pushed to move in the moving frame 574. The second cut surface seat 573 moves to fit with the first cut surface seat 572. As the second cut surface seat 573 continues to move, the first cut surface seat 572 will be pushed up, so that the installation shaft 3 obtains an upward force to adjust and correct it.
[0044] It should be noted that the inner ring of the first bearing 571 is fixedly connected to the mounting shaft 3, the outer wall is fixedly connected to the first section seat 572 via a connecting rod, and the weight of the first section seat 572 can prevent the outer ring from rotating.
[0045] like Figure 3-Figure 6 As shown, the reciprocating threaded rod 64 is movably mounted on the frame 63 through a first support assembly 68 and a second support assembly 69. The second support assembly 69 includes a movable opening 691 starting at one side of the frame 63, and also includes an arc seat 692 fixedly mounted on both sides of the reciprocating threaded rod 64. The movable opening 691 also includes a movable groove 694. One end of the arc seat 692 is located in the movable groove 694. A second spring 693 is fixedly mounted between the arc seat 692 and the movable groove 694.
[0046] When the reciprocating threaded rod 64 moves, it drives the arc seat 692 to squeeze the second spring 693 , so that the reciprocating threaded rod 64 moves in the movable opening 691 .
[0047] The first support assembly 68 includes a mounting tube 681 fixed on the frame 63, and also includes a support column 682 with one end located in the mounting tube 681, a first spring 683 is fixedly installed between the support column 682 and the mounting tube 681, and the other end of the support column 682 is fixedly connected to the reciprocating threaded rod 64.
[0048] When the reciprocating threaded rod 64 moves, it drives the support column 682 to move into the installation tube 681, so that the first spring 683 is compressed.
[0049] It should be noted that, in this embodiment, the pushing assembly 62 includes a second cam 66 rotatably mounted outside the frame 63 and in contact with one end of the reciprocating threaded rod 64, and also includes a third cam 67 rotatably mounted inside the frame 63 and in contact with the other end of the reciprocating threaded rod 64, and a force rod 621 with one end fixedly mounted on the second bearing 61, the other end of the force rod 621 is hinged to the second cam 66, the force rod 621 is fixedly connected to one end of an auxiliary rod 622, and the other end of the auxiliary rod 622 is hinged to the third cam 67.
[0050] When the mounting shaft 3 is offset, the second bearing 61 will be offset and drive the force rod 621 to move. The movement of the force rod 621 causes the second cam 66 to rotate and squeeze one end of the reciprocating threaded rod 64, causing this end to move downward, and the movement of the force rod 621 drives the auxiliary rod 622 to move, so that the third cam 67 will rotate and squeeze the other end of the reciprocating threaded rod 64 to move downward, thereby causing both ends of the reciprocating threaded rod 64 to move downward, causing the threaded disk 65 to contact the paper base, so that the threaded disk 65 rotates as the paper base moves through the friction between the two, and the threaded disk 65 will reciprocate on the reciprocating threaded rod 64, so that the uneven glue at the edge of the offset paper base is evenly coated, thereby reducing the generation of bubbles during subsequent compounding and avoiding unnecessary waste.
[0051] It should be noted that the outer ring of the second bearing 61 is fixedly connected to the pushing assembly 62, and the inner ring of the second bearing 61 is fixedly connected to the mounting shaft 3. When the mounting shaft 3 rotates, the inner ring of the second bearing 61 rotates, and the weight of the pushing assembly 62 will prevent the outer wall of the second bearing 61 from rotating with inertia.
[0052] It should also be noted that, in the present embodiment, a plurality of pressing roller groups evenly arranged along the length direction are provided between the two side plates 4, the pressing roller groups include two hot pressing rollers 7 symmetrically arranged up and down, and a gluing mechanism 8 is provided between the two side plates 4, the gluing mechanism 8 includes a coating roller rotatably installed between the two side plates 4, and also includes a glue liquid hopper for supplying material to the coating roller.
[0053] The shaft balance test method of the tobacco packaging liner paper aluminum foil composite equipment includes the following steps:
[0054] S1: The paper base and the aluminum foil are respectively unwound by the first unwinding roller 1 and the second unwinding roller 2, and the paper base contacts the coating roller for gluing. The glued paper base and the aluminum foil enter between two hot pressing rollers 7 for extrusion so that the paper base and the aluminum foil are compounded;
[0055] S2: When the installation shaft 3 is unbalanced, the installation shaft 3 will drive the first cam 53 and the first bearing 571 to deviate, causing them to move and change their positions. The rotation of the installation shaft 3 drives the first cam 53 to rotate and hit the force-bearing shaft 52. The reminder bell 900 in the force-bearing shaft 52 makes a sound to remind the staff. The force-bearing shaft 52 is forced to drop and squeeze the piston 59 through the push rod 583. The oil in the oil cylinder 54 is forced to squeeze out the extrusion rod 56. The extrusion rod 56 pushes the second section seat 573 to move. The second section seat 573 will contact the first section seat 572 and push up the first section seat 572, so that the first bearing 571 is pushed up and drives the installation shaft 3 to be adjusted and corrected in the first time without stopping.
[0056] S3: When the installation shaft 3 of the first unwinding roller 1 is offset, the installation shaft 3 will drive the second bearing 61 to change its position, and the second bearing 61 will drive the force rod 621 to move, and the force rod 621 will drive the second cam 66 to rotate and squeeze one end of the reciprocating threaded rod 64, and the movement of the force rod 621 will drive the auxiliary rod 622 to move, and the movement of the auxiliary rod 622 will drive the third cam 67 to squeeze the other end of the reciprocating threaded rod 64, and the position of the reciprocating threaded rod 64 will drop, so that the threaded disk 65 will contact the glued paper base, and as the paper base moves, the friction force generated by the two will drive the threaded disk 65 to rotate, and the rotation of the threaded disk 65 will reciprocate on the reciprocating threaded rod 64, so that the uneven glue at the edge of the offset paper base is evenly coated by the threaded disk 65.

The pressing roller group includes two hot pressing rollers (7) which are symmetrically arranged up and down. A gluing mechanism (8) is also provided between the two side plates (4). The gluing mechanism (8) includes a coating roller rotatably mounted between the two side plates (4) and also includes a glue liquid hopper for supplying material to the coating roller.
9. A method for testing the shaft balance of a tobacco packaging inner lining paper aluminum foil composite equipment, using the shaft balance testing device for tobacco packaging inner lining paper aluminum foil composite equipment according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1: The paper base and the aluminum foil are respectively unwound by a first unwinding roller (1) and a second unwinding roller (2), the paper base contacts a coating roller for gluing, and the glued paper base and the aluminum foil enter between two hot pressing rollers (7) for extrusion so that the paper base and the aluminum foil are laminated; S2: When the installation shaft (3) is unbalanced, the installation shaft (3) drives the first cam (53) and the first bearing (571) to deviate, causing them to move and change their positions. The rotation of the installation shaft (3) drives the first cam (53) to rotate and hit the force-bearing shaft (52). The reminder bell (900) in the force-bearing shaft (52) makes a sound to remind the staff. The force-bearing shaft (52) is forced to drop and squeeze the piston (59) through the push rod (583). The oil in the oil cylinder (54) is forced to squeeze out the extrusion rod (56). The extrusion rod (56) pushes the second section seat (573) to move. The second section seat (573) contacts the first section seat (572) and pushes up the first section seat (572), so that the first bearing (571) is pushed up and drives the installation shaft (3) to be adjusted and corrected immediately without stopping the machine. S3: When the mounting shaft (3) of the first unwinding roller (1) is unbalanced, the mounting shaft (3) drives the second bearing (61) to deviate, causing it to move and change its position. The second bearing (61) drives the force rod (621) to move. The force rod (621) drives the second cam (66) to rotate and squeeze one end of the reciprocating threaded rod (64). The movement of the force rod (621) drives the auxiliary rod (622) to move. The movement of the auxiliary rod (622) drives the third cam (67) to squeeze the other end of the reciprocating threaded rod (64). The position of the reciprocating threaded rod (64) decreases, causing the threaded disc (65) to contact the glued paper base. As the paper base moves, the friction force generated by the two drives the threaded disc (65) to rotate. The rotation of the threaded disc (65) reciprocates on the reciprocating threaded rod (64), so that the uneven glue at the edge of the offset paper base is evenly coated by the threaded disc (65).
