Description

Technical Field

[0001] This invention relates to the field of cigarette packaging machinery and equipment, and in particular to a synchronous positioning device for aluminum foil cigarette packs and inner frame paper, and a cigarette packaging machine. Background Technology

[0002] Cigarette packaging equipment is one of the main pieces of equipment in cigarette factories. After cigarette production, cigarettes need to be packed into boxes. An inner frame is usually placed inside the aluminum foil cigarette pack; this inner frame is mainly used to position the cigarette box lid. During cigarette pack production, equipment is used to insert the inner frame into the cigarette box, and the position of the inner frame within the aluminum foil cigarette pack is fixed to facilitate subsequent packaging operations.

[0003] Traditional inner frame paper positioning devices use a slotted cam mechanism 3 to position the inner frame paper 9 of the cigarette box. For example... Figure 1 As shown, in the existing device, when the aluminum foil cigarette pack 11 and the inner frame paper 9 are placed together in the packaging tray mold and conveyed to the inner frame paper positioning device, the transverse pressing plate 801 of the inner frame paper positioning device moves downward under the action of the slot cam mechanism 3 and presses on the inner frame paper 9, so that the inner frame paper 9 and the aluminum foil cigarette pack 11 are in contact, eliminating the gap (the gap is S); after the transverse pressing plate 801 completes the pressing, the slot cam mechanism 3 lifts the transverse pressing plate 801 away from the aluminum foil cigarette pack 11, the packaging tray mold rotates, and the aluminum foil cigarette pack 11 is transported to the next process.

[0004] However, during the process of placing the aluminum foil cigarette pack 11 and the inner frame paper 9 together in the packaging tray mold, there may be front-to-back positional deviations between the aluminum foil cigarette pack 9 and the packaging tray mold, as well as front-to-back positional deviations between the aluminum foil cigarette pack 11 and the inner frame paper 9. This can cause the inner frame paper 9 to be misplaced. The inner frame paper positioning device only provides a vertical downward force and cannot adjust the positioning in the front-to-back direction, which affects subsequent packaging operations. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a synchronous positioning device for aluminum foil cigarette packs and inner frame paper, and a cigarette packaging machine, to solve the problem that the cam linkage mechanism in the prior art only exerts a downward force on the inner frame paper, and cannot solve the problem of front-to-back positional deviation between the aluminum foil cigarette pack and the inner frame paper, and between the aluminum foil cigarette pack and the packaging tray mold box.

The pressing transmission assembly includes a spatial connecting rod, a pressing swing rod, and a pressing block.

[0024] like Figure 2 , Figure 3 As shown, the present invention provides a synchronous positioning device for aluminum foil cigarette packs and inner frame paper (hereinafter referred to as the positioning device), including a pressing drive assembly, a pressing transmission assembly connected to the pressing drive assembly, the pressing transmission assembly including a spatial connecting rod 6, a pressing swing rod 7, and a pressing block 8, the bottom end of the spatial connecting rod 6 is hinged to the pressing swing rod 7, the pressing swing rod 7 and the pressing block 8 are fixedly connected, a fixed bracket 5 is also provided on the outer side of the pressing block 8, and the pressing block 8 is hinged to the fixed bracket 5; the pressing block 8 includes a horizontal pressing plate 801 and a vertical pressing plate 802, the horizontal pressing plate 801 and the vertical pressing plate 802 are fixedly connected.

[0025] The present invention relates to a synchronous positioning device for aluminum foil cigarette packs and inner frame paper, which includes a pressing transmission assembly. The pressing transmission assembly includes a spatial connecting rod 6, a pressing swing rod 7, and a pressing block 8. The pressing drive assembly drives the spatial connecting rod 6 to move up and down, and the spatial connecting rod 6 drives the pressing swing rod 7 to swing, thereby causing the pressing block 8 to rotate around the fixed support 5. The horizontal pressing plate 801 on the pressing block 8 provides a vertical pressure to press the inner frame paper 9 downward, eliminating the gap between the inner frame paper 9 and the aluminum foil cigarette pack 11. The vertical pressing plate 802 on the pressing block 8 provides a backward thrust during the rotation process, pushing the aluminum foil cigarette pack 11 to a fixed position, and at the same time, it can also push the inner frame paper 9 to move on the aluminum foil cigarette pack 11, so that the inner frame paper 9 reaches the fixed position. Precise positioning facilitates the smooth progress of subsequent packaging work.

[0026] Preferred, such as Figure 2 , Figure 4 , Figure 5As shown, the pressing drive assembly includes a pressing drive power source, a slotted cam mechanism 3, and a transmission rocker arm 4. The pressing drive power source is connected to the slotted cam mechanism 3, and the pressing drive power source is connected to the transmission rocker arm 4 through the slotted cam mechanism 3. The left end of the transmission rocker arm 4 is connected to the slotted cam mechanism 3, and the right end is hinged to the spatial connecting rod 6. Further, the slotted cam mechanism 3 includes a cam slot 301, a cam 302, a driven wheel 303, and a cam driven rod 304. The driven wheel 303 is disposed between the cam 302 and the cam slot 301. The upper end of the cam driven rod 304 is hinged to the driven wheel 303, and the lower end is fixedly connected to the transmission rocker arm 4.

[0027] Preferred, such as Figure 2 , Figure 3 , Figure 5 As shown, the positioning device also includes a fixed plate 1. The pressing drive power source is mounted on the fixed plate 1 with screws, and the fixed bracket 5 is fastened to the fixed plate 1 with bolts. A rotating shaft 101 is rotatably connected to the fixed plate 1 via a bearing. Furthermore, both the upper and lower ends of the cam follower 304 are provided with through holes. The through hole at the upper end of the cam follower 304 is sleeved on the central shaft of the driven wheel 303, and the through hole at the lower end is fixedly connected to the rotating shaft 101 via a flat key. The lower end of the cam follower 304 is also fixedly connected to the transmission rocker arm 4. When the driven wheel 303 is offset in the cam groove 301 by the action of the cam 302, the upper end of the cam follower 304, which is hinged to the driven wheel 303, is offset. Consequently, the lower end of the cam follower 304 will drive the rotating shaft 101 to rotate, thereby driving the rocker arm 4 to swing up and down, realizing the transmission of torque. Furthermore, in this embodiment, the pressing drive power source and the cam 302 are driven by a motor and gear meshing transmission. In other embodiments, other transmission methods may also be used.

[0028] Preferred, such as Figure 2 As shown, the positioning device also includes a packaging tray 2, with a fixing plate 1 installed directly above the packaging tray 2. A plurality of packaging tray molds 201 are evenly arranged on the sidewalls of the packaging tray 2, with the same angular spacing between adjacent packaging tray molds 201. Further, in this embodiment, the packaging tray 2 is a regular octagon, with eight packaging tray molds 201 arranged on each sidewall of the regular octagonal packaging tray 2, and the angular spacing between adjacent packaging tray molds 201 is 45°. Further, in this embodiment, a rotary drive assembly (not shown) is also connected to the packaging tray 2. The rotary drive assembly includes a rotary drive power source and a rotary transmission assembly. The rotary drive power source is located at the midpoint of the regular octagonal packaging tray 2 and is driven by a motor and gear meshing transmission. In other embodiments, other transmission methods may also be used.

[0029] Preferred, such as Figure 2As shown, the positioning device also includes a cigarette pack pusher 10, which is disposed on the front side of any packaging tray mold 201, and the pressing drive assembly is disposed on the upper side of the same packaging tray mold 201. In this embodiment, the cigarette pack pusher 10 pushes the aluminum foil cigarette pack 11 and the inner frame paper 9 together into the packaging tray mold 201. The pressing drive assembly controls the horizontal pressing plate 801 on the pressing block 8 to press the inner frame paper 9 vertically through the pressing transmission assembly, eliminating the vertical gap between the inner frame paper 9 and the aluminum foil cigarette pack 11; at the same time, the vertical pressing plate 802 exerts a pushing force on the aluminum foil cigarette pack 11 and the inner frame paper 9 along the pushing direction of the cigarette pack pusher 10, so that the aluminum foil cigarette pack 11 and the inner frame paper 9 move to a fixed position, which facilitates subsequent packaging operations.

[0030] Preferred, such as Figure 3 , Figure 5 As shown, the fixed bracket 5 is U-shaped, and the pressing block 8 is rotatably disposed between the opposite side walls of the U-shaped fixed bracket 5 via a connecting pin. The connecting pin passes through the fixed bracket 5 and is fixedly connected to the pressing swing rod 7. Further, in this embodiment, the fixed bracket 5 has two through holes, and fastening bolts are inserted into the two through holes. The fixed bracket 5 is mounted on the front end face of the fixed plate 1 by the two fastening bolts. In other embodiments, the positioning device can also be provided with a protective shell, and the fixed bracket 5 is mounted on the protective shell by fastening bolts. The function of the fixed bracket 5 is to provide a hinge point for the pressing block 8 to flip, thereby preventing the pressing block 8 from moving up and down with the spatial connecting rod 6.

[0031] Preferred, such as Figure 3 , Figure 5 As shown, a deflection pin 701 is also provided on the pressing swing arm 7. The bottom end of the spatial connecting rod 6 is hinged to the deflection pin 701, and the central axis of the deflection pin 701 does not coincide with the central axis of the connecting pin. Further, in this embodiment, the deflection pin 701 and the central axis of the connecting pin are parallel but not coincident, which facilitates the deflection of the pressing swing arm 7. The smaller the distance between the deflection pin 701 and the connecting pin, the greater the force required to deflect the pressing swing arm 7; the greater the distance between the deflection pin 701 and the connecting pin, the smaller the force required to deflect the pressing swing arm 7. Further, the bottom end of the pressing swing arm 7 is sleeved on the deflection pin 701, and a joint bearing is also provided between the pressing swing arm 7 and the deflection pin 701 to buffer the frictional force between the pressing swing arm 7 and the deflection pin 701.

[0032] Preferred, such as Figure 3As shown, the horizontal pressing plate 801 is fixed parallel to the bottom surface of the pressing block 8, and the vertical pressing plate 802 is fixed vertically to the bottom surface of the pressing block 8. The horizontal pressing plate 801 and the vertical pressing plate 802 are integral parts. In this embodiment, the horizontal pressing plate 801 and the vertical pressing plate 802 are perpendicular to each other. Furthermore, the thickness of the horizontal pressing plate 801 is the same at all points, which allows the surface of the inner frame paper 9 to be uniformly stressed. The thickness of the inner wall where the vertical pressing plate 802 connects to the horizontal pressing plate 801 is the same at all points. When the pressing block 8 flips, the bottom of the vertical pressing plate 802 first contacts the aluminum foil cigarette pack 11 or the inner frame paper 9. At this time, the distance between the connecting pin of the pressing block 8 and the aluminum foil cigarette pack 11 or the inner frame paper 9 is the hypotenuse of the triangle formed by the vertical pressing plate 802 and the horizontal pressing plate 801. As the pressing block 8 rotates, the distance between the connecting pin of the pressing block 8 and the aluminum foil cigarette pack 11 or the inner frame paper 9 gradually decreases. The vertical pressing plate 802 pushes the aluminum foil cigarette pack 11 or the inner frame paper 9 until the distance between the connecting pin and the aluminum foil cigarette pack 11 or the inner frame paper 9 is equal to the length of the horizontal pressing plate 801. Therefore, the front and back positions of the aluminum foil cigarette pack 11 on the packaging tray mold box 201 and the front and back positions of the inner frame paper 9 on the aluminum foil cigarette pack 11 can be set by the length of the horizontal pressing plate 801, which is suitable for cigarettes of different specifications.

[0033] Furthermore, in this embodiment, the pressing drive power source, the rotation drive power source, and the power source of the cigarette pack pusher 10 are all the same total power source. The working states of the slot cam mechanism 3, the packaging plate 2, and the cigarette pack pusher 10 are all controlled by the phase angle coordination between the mechanical components. The mechanical components and the phase coordination angle between the mechanical components are all existing technologies.

[0034] The aluminum foil cigarette pack and inner frame paper synchronous positioning device involved in this invention, when in use, as follows: Figure 2 , Figure 4 As shown, the operator opens the positioning device, and the main power source drives the cigarette pack pusher 10 to work, pushing the aluminum foil cigarette pack 11 and the inner frame paper 9 into the packaging tray mold box 201 (the combination of the aluminum foil cigarette pack 11 and the inner frame paper 9 is completed by another mechanical structure, which is existing technology). The main power source drives the pressing drive power source to work through the mechanical components. The pressing drive power source drives the cam 302 to rotate through gear meshing transmission. When the tip of the cam 302 contacts the driven wheel 303, the driven wheel 303 is displaced radially along the cam groove 301, causing the cam driven rod 304 to deflect. The bottom end of the cam driven rod 304 drives the rotating shaft 101 to rotate through the flat key, which in turn drives the transmission rocker arm 4 to deflect. The deflection of the transmission rocker arm 4 causes the spatial connecting rod 6 to move downward. The deflection pin 701 on the pressing rocker arm 7 is subjected to a downward force, causing the pressing rocker arm 7 to deflect around the connecting pin. Then the pressing block 8 follows the pressing rocker arm 7 to rotate clockwise.

[0035] During the clockwise rotation of the pressing block 8, with the packaging tray mold 201 as the positioning reference, the aluminum foil cigarette pack 11, the inner frame paper 9, and the packaging tray mold 201 have the following positional relationships:

[0036] 1. When there is a front-to-back deviation between the aluminum foil cigarette pack 11 and the packaging tray mold 201, but no front-to-back deviation between the inner frame paper 9 and the packaging tray mold 201.

[0037] At this time, the pressing block 8 rotates clockwise, and the bottom of the vertical pressing plate 802 contacts the aluminum foil cigarette pack 11 first. At this time, the vertical pressing plate 802, the horizontal pressing plate 801, and the aluminum foil cigarette pack 11 form a right triangle, with the vertical pressing plate 802 and the horizontal pressing plate 801 as the right angle sides, and the horizontal distance between the connecting pin of the pressing block 8 and the aluminum foil cigarette pack 11 as the hypotenuse. As the pressing block 8 rotates, the horizontal distance between the connecting pin of the pressing block 8 and the aluminum foil cigarette pack 11 gradually decreases, and the aluminum foil cigarette pack 11 is pushed by the vertical pressing plate 802 until the rotation is completed. At this time, the horizontal distance between the connecting pin of the pressing block 8 and the aluminum foil cigarette pack 11 is equal to the length of the horizontal pressing plate 801. Therefore, the aluminum foil cigarette pack 11 moves back and forth in the packaging tray mold box 201 until the positional deviation is overcome.

[0038] II. When there is no front-to-back deviation between the aluminum foil cigarette pack 11 and the packaging tray mold 201, but there is a front-to-back deviation between the inner frame paper 9 and the packaging tray mold 201.

[0039] At this time, the pressing block 8 rotates clockwise, and the bottom of the vertical pressing plate 802 contacts the inner frame paper 9 first. At this time, the vertical pressing plate 802, the horizontal pressing plate 801, and the inner frame paper 9 form a right triangle, with the vertical pressing plate 802 and the horizontal pressing plate 801 as the right angle sides, and the horizontal distance between the connecting pin of the pressing block 8 and the inner frame paper 9 as the hypotenuse. As the pressing block 8 rotates, the horizontal distance between the connecting pin of the pressing block 8 and the inner frame paper 9 gradually decreases, and the inner frame paper 9 is pushed by the vertical pressing plate 802 until the rotation is completed. At this time, the horizontal distance between the connecting pin of the pressing block 8 and the inner frame paper 9 is equal to the length of the horizontal pressing plate 801. Therefore, the inner frame paper 9 moves back and forth on the aluminum foil cigarette pack 11 until the positional deviation is overcome.

[0040] 3. When there is a front-to-back deviation between the aluminum foil cigarette pack 11 and the packaging tray mold 201, or a front-to-back deviation between the inner frame paper 9 and the packaging tray mold 201, or a front-to-back deviation between the aluminum foil cigarette pack 11 and the inner frame paper 9...

[0041] At this time, the pressing block 8 rotates clockwise, and the bottom of the vertical pressing plate 802 first contacts the inner frame paper 9 / aluminum foil cigarette pack 11. At this time, the vertical pressing plate 802, the horizontal pressing plate 801, and the inner frame paper 9 / aluminum foil cigarette pack 11 form a right triangle, with the vertical pressing plate 802 and the horizontal pressing plate 801 as the right angle sides, and the horizontal distance between the connecting pin of the pressing block 8 and the inner frame paper 9 / aluminum foil cigarette pack 11 as the hypotenuse. As the pressing block 8 rotates, the horizontal distance between the connecting pin of the pressing block 8 and the inner frame paper 9 / aluminum foil cigarette pack 11 gradually decreases. Then, the vertical pressing plate 802 contacts the inner frame paper 9 and the aluminum foil cigarette pack 11 at the same time. The inner frame paper 9 / aluminum foil cigarette pack 11 is pushed by the vertical pressing plate 802 at the same time until the rotation is completed. At this time, the inner frame paper 9 moves back and forth on the aluminum foil cigarette pack 11 to overcome the positional deviation, and the aluminum foil cigarette pack 11 moves back and forth on the packaging tray mold box 201 to overcome the positional deviation.

[0042] When the aluminum foil cigarette pack 11 and the inner frame paper 9 reach the set position under the push of the vertical pressing plate 802, the horizontal pressing plate 801 presses on the inner frame paper 9, so that the inner frame paper 9 presses down on the aluminum foil cigarette pack 11, eliminating the gap between the inner frame paper 9 and the aluminum foil cigarette pack 11.

[0043] As the cam 302 rotates, the spatial linkage 6 gradually rises, the pressing block 8 flips counterclockwise, and the total power source drives the rotary drive power source to work through the mechanical components. The rotary drive power source drives the packaging disc 2 to rotate through gear meshing, which transmits the pressed aluminum foil cigarette pack 11 out and performs the next pressing and positioning cycle.

[0044] The present invention relates to a synchronous positioning device for aluminum foil cigarette packs and inner frame paper, which employs a slotted cam mechanism 3, a cam driven rod 304, a transmission swing rod 4, a spatial connecting rod 6, and a pressing block 8. The cam 302 drives the spatial four-bar linkage mechanism, with the cam 302 as the input component and the pressing block 8 as the output component. The flipping and swinging of the pressing block 8 synchronously clamps and positions the aluminum foil cigarette pack 11 and the inner frame paper 9, eliminating the front-to-back positional deviation between the aluminum foil cigarette pack 11 and the packaging tray mold 201, as well as the positional deviation between the inner frame paper 9 and the aluminum foil cigarette pack 11, ensuring smooth subsequent packaging operations. Compared to traditional inner frame paper positioning devices, this positioning device adds positioning for the front-to-back positional deviation between the aluminum foil cigarette pack 11 and the inner frame paper 9, effectively ensuring accurate positioning and guaranteeing subsequent packaging operations.

[0045] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
