Description

Technical Field

[0001] This invention relates to the tobacco industry, and in particular to a support device for a label paper turntable. Background Technology

[0002] Tobacco packaging machines are mainly used for the production of cigarette outer packaging. This outer packaging includes inner lining paper, white cardboard, and label paper. Therefore, the packaging machine involves the production and assembly of these materials. For example... Figure 1 and Figure 2 As shown, the label paper 200 includes a label paper box body 210, a box lid inner tongue 220, and a short folded paper flap 230. When the white cardboard and label paper 200 are assembled, the label paper 200 is located on the label paper station 110 of the label paper turret 100. The label paper turret 100 includes several label paper stations 110 and a rotating label paper turntable 120, which is approximately equilateral polygonal, and the label paper stations 110 are located on the sides of the polygon. The label paper station 110 is essentially an open box for receiving the label paper 200. The label paper station 110 includes a bottom wall and two side walls 112, wherein the working opening 111 of the label paper station faces away from the label paper turntable 120. When the label paper 200 is located at the label paper station 110, the short folded paper flap 230 and the box lid inner tongue 220 both extend from the working opening 111 of the label paper station.

[0003] When the label paper 200 rotates with the label paper station 110 to the white cardboard assembly position, the white cardboard is directly fed into the label paper 200 from the working opening 111 side of the label paper station. Then, under the rotation of the label paper turret 100, it is carried away by the label paper station 110 and fed into the next label paper 200 at the next label paper station 110. However, in the prior art, this process often results in phenomena such as "flying white cardboard," meaning that the white cardboard fails to enter the label paper smoothly and flies out, causing defects in the cigarette outer packaging, affecting packaging efficiency and the economic benefits of the cigarette factory.

DETAILED DESCRIPTION

[0022] The present application is herein described, by way of example only, with reference to embodiments thereof. It is contemplated that deviations in form can be made that fall within the scope of the application and that the application can be practiced in ways other than those specifically described herein.

[0023] It should be understood that the structures, proportions, sizes, etc. shown in the attached drawings, are chosen exclusively for purposes of illustration only and that modifications in form, proportions and sizes can be made without departing from or essentially affecting the spirit and scope of the application. Accordingly, other embodiments are within the scope of the following claims so far as they are not mutually inconsistent therewith.

[0024] As Figures 1-7As shown, the trademark paper turntable 100 uses the opening device, which includes an opening mechanism 300, a base 600, a driving mechanism 320 and a trademark paper station 110. The driving mechanism 320 includes a driving connection part 321 and a driving part connected to the first end of the driving connection part 321, which is used to drive the second end of the driving connection part 321 to swing back and forth in the vertical direction. The opening mechanism 300 includes an opening part 310 and a first connecting rod mechanism 330. The opening part 310 includes an opening connection part 312 connected to the opening part 311, and the opening part 311 is arranged corresponding to the trademark paper station working opening 111. The opening connection part 312 is rotationally connected to the fixed part. The second end of the first connecting rod mechanism 330 is connected to the opening connection part 312, and the first end of the first connecting rod mechanism 330 is connected to the second end of the driving connection part 321, which is used to drive the opening connection part 312 to press and extend the short folded paper page 230 out of the trademark paper station working opening 111.

[0025] When the trademark paper 200 is located in the predetermined trademark paper station 110, the short folded paper page 230 extends out of the trademark paper station opening 111, and the crease between the short folded paper page 230 and the trademark paper box body 210 is located at the end edge of the two station side walls 120 of the trademark paper station 110. The driving part drives the second end of the driving connection part 321 to swing back and forth in the vertical direction. In this embodiment, that is, the driving connection part 321 swings back and forth by a certain angle around the driving shaft 322 connected to the first end of the driving connection part 321 in the vertical direction. The swinging driving connection part 321 drives the second end of the first connecting rod mechanism 330 to rotate back and forth around the connection between the opening connection part 312 and the base 600, thereby realizing the continuous cooperation of the opening connection part 312 with the side edges of the two side walls of the trademark paper station 110, pressing and extending the short folded paper page 230 out of the working opening of the trademark paper station 110, and realizing the opening of the short folded paper page 230 towards the two sides.

[0026] That is, when the trademark paper turntable 100 stops, the opening part 311 moves towards the trademark paper station 110 to open the short folded paper page 230, and after the opening action is completed, the opening part 311 moves away from the trademark paper station 110, and the trademark paper turntable 100 rotates, thereby continuously realizing the opening of the short folded paper page 230 of the trademark paper 200 in the predetermined position of the trademark paper station 110. After the opening action of the opening part 311, the short folded paper page 230 is in an open state towards the outside, effectively avoiding the knocking of the white card paper during the input of the trademark paper 200, and reducing the phenomenon of trademark paper 200 fly white card. It should be noted that the structure of the opening part 311 is simple, and can be designed as a structure that can push the short folded paper page 230 when moving towards the trademark paper station 110. Here, the vertical plane direction is the direction perpendicular to the plane of the paper.Figure 3 The vertical direction is used as the reference.

[0027] like Figure 4 and Figure 5 As shown, to facilitate the disassembly and maintenance of the spreading mechanism 300, the spreading mechanism 300 also includes a fixed base 340 detachably connected to the base 600, and the spreading connecting part 312 is rotatably connected to the fixed base 340. In this embodiment, the fixed base 340 and the base 600 are connected by bolts and nuts. During disassembly, it is only necessary to detach the first end of the first linkage mechanism 330 from the drive connecting part 321 and detach the fixed base 340 from the base 600 to remove the spreading mechanism 300 from the entire spreading device.

[0028] like Figure 4 and Figure 5 As shown, the first linkage mechanism 330 can preferably include a first link 331 and a rocker arm 332. The second end of the first link 331 is rotatably connected to the first end of the rocker arm 332. The first end of the first link 331 forms the first end of the first linkage mechanism 330, and the second end of the rocker arm 332 forms the second end of the first linkage mechanism 330.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the drive connection 321 is located approximately diagonally above the predetermined label paper station 110. The second end of the drive connection 321, the second end of the first connecting rod 331, and the second end of the swing rod 332 are arranged approximately from near the predetermined label paper station 110 toward near the drive connection. When the second end of the drive connection 321 swings toward the predetermined label paper station 110, the swing rod 332 swings downward under the drive of the first connecting rod 331, thereby causing the opening part 311 to swing around the connection between the opening connection 312 and the fixed seat 340 toward the predetermined label paper station 110, thus opening the short folded paper sheet 230. Correspondingly, when the second end of the drive connection 321 swings away from the predetermined label paper station 110, the opening part 311 separates from the short folded paper sheet 230, facilitating the rotation of the label paper turntable 100. The first linkage mechanism 330 not only enables the drive unit to continuously expand the short folded paper sheet 230 transported to the predetermined position by driving the expansion member 310, but also enables the entire expansion device to be set in a narrow space, especially in a long and narrow space.

[0030] like Figure 6As shown, in particular, the trademark paper turntable 100 with the opening device further comprises a second connecting rod mechanism 400, a box cover inner tongue pressing part 500, and a box cover pressing seat 500 under the box cover inner tongue pressing part 510; the first end of the second connecting rod mechanism 400 is connected to the second end of the driving connecting part 321, and the second end of the second connecting rod mechanism 400 is connected with the box cover inner tongue pressing part 510, for driving the box cover inner tongue pressing part 510 to press the box cover inner tongue 220 extending out of the working opening of the trademark paper station 110, wherein the box cover pressing seat 500 is located on the machine base 600.

[0031] When the trademark paper 200 is located at the predetermined trademark paper station 110, the box cover inner tongue 220 extends out of the working opening 111 of the trademark paper station and is located on the box cover inner tongue pressing seat 500. The second end of the driving part driving connecting part 321 reciprocates in the vertical direction, driving the second end of the second connecting rod mechanism 400 to reciprocate, so as to realize the continuous pressing of the box cover inner tongue pressing part 510 on the box cover inner tongue 220. That is, when the trademark paper turntable 100 stops, the box cover inner tongue pressing part 510 moves towards the box cover inner tongue pressing seat 500 to press the box cover inner tongue 220; when the pressing of the box cover inner tongue pressing part 510 is completed, the box cover inner tongue pressing part 510 moves away from the box cover inner tongue 220 pressing seat, and the trademark paper turntable 100 rotates.

[0032] The driving connecting part 321 simultaneously connects the first connecting rod mechanism 330 and the second connecting rod mechanism 400, respectively driving the opening member 310 to open the short folded paper sheet 230 and the box cover inner tongue pressing part 510 to press the box cover inner tongue 220. Not only the synchronous operation of the opening of the short folded paper sheet 230 and the pressing of the box cover inner tongue 220 is realized, but also the interference of the white card paper with the short folded paper sheet 230 and the box cover inner tongue 220 when the white card paper is input into the trademark paper 200 is effectively avoided. At the same time, due to the application of the same power source, the cost is saved, and the occupied space of the equipment is reduced.

[0033] As shown in Figure 3 and Figure 6 , the second connecting rod mechanism 400 comprises a second connecting rod one 410, a second connecting rod two 420, and a second connecting rod three 430. The second end of the second connecting rod one 410 is rotationally connected to the first end of the second connecting rod two 420, the second end of the second connecting rod two 420 is rotationally connected to the first end of the second connecting rod three 430, the second end of the second connecting rod three 430 is connected to the rack, and the box cover inner tongue pressing part 500 is fixed on the second connecting rod three 430; wherein the first end of the second connecting rod one 410 forms the first end of the second connecting rod mechanism 400, and the second connecting rod three 430 forms the second end of the second connecting rod mechanism 400, that is, the box cover inner tongue pressing part 500 is directly fixed on the second connecting rod three 430.

[0034] As shown in Figure 3 and Figure 6As shown, in the embodiment, the swing of the driving connecting part 321 is transmitted through the second connecting rod mechanism 400, so that the inner lid tongue pressing part 500 presses the inner lid tongue 220 of the trademark paper turntable 100. Preferably, the second connecting rod mechanism 400 further comprises a second connecting rod four 440, the first end of the second connecting rod four 440, the first end of the second connecting rod two 420 and the second connecting rod one 410 are all rotationally connected, and the second end of the second connecting rod four 440 is rotationally connected to the base 700, so that the second connecting rod mechanism 400 operates more stably.

[0035] As shown in Figure 3 and Figure 7 As shown, the first end of the driving connecting part 321 is provided with a driving connecting end part three 3210 connected with the driving part, the second end of the driving connecting part 321 is provided with a driving connecting end part one 3211 connected with the first connecting rod mechanism 330 and a driving connecting end part two 3212 connected with the second connecting rod mechanism 400; the connecting line between the driving connecting end part three 3210 and the driving connecting end part one 3211 and the connecting line between the driving connecting end part two 3212 and the driving connecting end part three 3210 are located on two intersecting vertical planes. The driving connecting part 321 is arranged in this way, which facilitates the specific arrangement of the first connecting rod 331 mechanism 330 and the second connecting rod mechanism 400, and can reduce the occupied space of the two mechanisms while avoiding mutual interference between the first connecting rod 331 mechanism 330 and the second connecting rod mechanism 400.

[0036] As shown in Figure 7 As shown, in the embodiment, the driving connecting part 321 comprises a main body part 321a and a curved part 321b, the curved part 321b is bent towards one side and deviates from the plane where the main body part 321a is located. The driving connecting end part one 3211 is located on the curved part 321b, the connecting end part three and the connecting end part two are located on the main body part 321a, the driving connecting end part one 3211 and the driving connecting end part two 3212 are located at the same end, that is, the second end of the driving connecting part 321; the driving connecting part three 3210 is located at the other end, that is, the first end of the driving connecting part 321. In the embodiment, the driving connecting end part three 3210 is a shaft hole connected with the driving shaft 323, and the driving connecting part 321 rotates around the shaft hole axis L.

[0037] Specifically, the driving part can be a driving motor, the output shaft of the driving motor is connected with the first end of the driving connecting part 321, for driving the second end of the driving connecting part 321 to swing. Of course, the driving part can be other power sources that can drive the second end of the driving connecting part 321 to reciprocate small amplitude rotation around the first end of the driving connecting part 321.
