[0031] The utility model provides a six-side shaping device for cigarette boxes including a U-shaped conveying mechanism, which includes a first shaping station 100, a second shaping station 200 and a third shaping station 300 which are arranged in sequence.

[0032] The first shaping station 100 includes a first conveying assembly 110 and a first shaping module 120. When the cigarette box is transported on the first conveying assembly 110, the first shaping module 120 can at least shape the transparent paper on the first end surface of the cigarette box.

When the cigarette box is transported on the second conveying assembly 210, the second shaping module 220 can at least shape the transparent paper on the other end faces except the first end face.

[0034] The third shaping station 300 includes a third conveying assembly 310 and a third shaping module 320. When the cigarette box is transported on the third conveying assembly 310, the third shaping module 320 can shape the transparent paper on the remaining end surface;

[0035] The first conveying assembly 110 , the second conveying assembly 210 , and the third conveying assembly 310 are connected end to end, and the first conveying assembly 110 and the third conveying assembly 310 are arranged on the same side of the second conveying assembly 210 , and the two and the second conveying assembly 210 form a “U”-shaped arrangement.

[0036] The first conveying assembly 110, the second conveying assembly 210 and the third conveying assembly 310 are all configured as a long strip conveying mode, and the first conveying assembly 110, the second conveying assembly 210 and the third conveying assembly 310 are sequentially connected end to end. The cigarette box first enters the first conveying assembly 110 under the action of the feeding mechanism, and the transparent paper on the first end surface of the cigarette box is ironed and shaped at the first shaping station 100. After the shaping is completed, the cigarette box reaches the end of the first conveying assembly 110 under the action of the first conveying assembly 110, and enters the second conveying assembly from the side. 210, that is, enters the second shaping station 200, and during the conveyance on the second conveying component 210, it is ironed and shaped by the second shaping module 220, and the shaping surface is the other end surface except the first end surface; when the cigarette box reaches the end of the second conveying component 210, it immediately enters the third conveying component 310, that is, enters the third shaping station 300, and under the conveyance of the third conveying component 310, it is ironed and shaped by the third shaping module 320, and after the transparent paper on the remaining end surfaces is ironed and shaped, it is conveyed to the end of the third shaping station 300 for unloading.

[0037] It should be noted that the above-mentioned “first end face”, “other end faces except the first end face” and “remaining end faces” can be one end face or multiple end faces, and the number of end faces is not a design point of the above-mentioned technical solution.

[0038] The above three shaping modules are usually arranged on the side or above the conveying assembly according to the position of the cigarette box. In this embodiment, the first shaping module 120 and the third shaping module 320 are ironing assemblies respectively arranged on the side of the first conveying assembly 110 and the third conveying assembly 310, and are used to iron the side end surfaces of the cigarette box; the second shaping module 220 is an ironing assembly arranged above the second conveying assembly 210, and is used to iron the upper and lower end surfaces of the cigarette box. The ironing assembly used for shaping in this embodiment is consistent with the ironing assembly structure for shaping the transparent paper of the cigarette box in the prior art, and will not be described in detail here.

[0039] Based on the above settings, the first conveying component 110 and the third conveying component 310 are arranged on the same side of the second conveying component 210, and the first conveying component 110 and the second conveying component 210 are arranged vertically, and the third conveying component 310 and the second conveying component 210 are also arranged vertically to complete the U-shaped position arrangement, make full use of the space, and minimize the occupied area of ​​the equipment. At the same time, under this setting, the management personnel only needs to stand on one side to complete the management of the three workstations.

[0040] Compared with the prior art, the beneficial effects of the present invention are as follows: the three shaping stations are arranged in a U shape, which reduces the space occupied by the equipment, and through reasonable layout, the three conveying components are seamlessly connected, and the cigarette box can be smoothly conveyed to the next station; at the same time, the management personnel only need to be on one side to manage the three stations at the same time, and the automation efficiency is high.

[0041] The specific arrangement of the above three workstations is as follows: the two ends of the first transmission component 110 are set as the first starting end and the first output end 102 according to the transmission direction; the two ends of the second transmission component 210 are set as the second starting end 201 and the second output end according to the transmission direction; the two ends of the third transmission component 310 are set as the third starting end and the third output end according to the transmission direction; the second starting end 201 is located on the second side of the first output end 102, and the second output end is located on the first side of the third starting end. Here, the first side and the second side are relative concepts. The second side of the first output end 102 is the side facing and close to the workstation manager, and the first side of the third starting end is the side facing and close to the workstation manager. With such an arrangement, seamless connection between the three transmission components can be achieved to prevent the cigarette box from falling from the transmission component when entering the next workstation, affecting the automation process.

[0042] In the above-mentioned six-sided shaping device for cigarette boxes including the U-shaped conveying mechanism, the shaping module performs shaping actions on the cigarette boxes during the conveying process. Therefore, the conveying process needs to set an operation time to avoid damage caused by the movement of the cigarette boxes during the ironing process. Therefore, the shaping device also includes an intermittent transmission module for driving the first conveying assembly 110 and the third conveying assembly 310 to perform intermittent transmission. As for the intermittent transmission of the cigarette boxes on the second conveying assembly 210, the cigarette boxes are driven by themselves.

[0043] The intermittent transmission module can be a servo motor capable of realizing intermittent transmission, or it can be realized through the following transmission mechanism.

[0044] Specifically, the intermittent transmission module may include a main shaft 600, a groove wheel mechanism 700, two gear sets 800 and two pulley sets 900 which are sequentially connected; the main shaft 600 is connected to a main shaft driving mechanism, and under the action of the driving mechanism, the main shaft 600 drives the groove wheel mechanism 700 to rotate intermittently, and then the groove wheel mechanism 700 simultaneously transmits the two gear sets 800 during rotation, and the two gear sets 800 respectively drive the two pulley sets 900 to rotate intermittently, and finally the two pulley sets 900 respectively drive the first transmission component 110 and the third transmission component 310 to perform intermittent transmission.

[0045] The groove wheel mechanism 700 may include a thumbwheel 720 disposed on the main shaft 600 and rotating therewith, and a groove wheel 710 that can cooperate with the thumbwheel 720; an eccentric shaft 730 is disposed on the thumbwheel 720 in the direction toward the groove wheel 710, and the eccentric shaft 730 can be inserted into the radial groove 711 of the groove wheel 710, and the groove wheel 710 is sleeved on the transmission shaft 1.

[0046] The gear set 800 may include an input gear 810 and an output gear 820 of a gear transmission, and the pulley set 900 may include a driving wheel 910 and a driven wheel 920 of a belt transmission, wherein the input gear 810 is coaxially arranged with the groove wheel 710 and rotates synchronously, the driving wheel 910 and the output gear 820 are coaxially arranged, and the driven wheel 920 is used to drive the first transmission assembly 110 or the third transmission assembly 310. In use, the rotation of the groove wheel 710 drives the input gear 810 to rotate synchronously, thereby driving the output gear 820 to rotate, and the rotation of the output gear 820 can drive the driving wheel 910 to rotate synchronously, thereby driving the driven wheel 910 to rotate the driven wheel 920.

[0047] The first conveying assembly 110 and the third conveying assembly 310 are both provided with conveyor belts, and rotating parts are provided at both ends of the conveyor belts. The driven wheel 920 is connected to the rotating parts to drive the rotating parts to rotate. A block may also be provided on one side of the conveyor belt for conveying the cigarette box, and the cigarette box is located between two adjacent blocks; the distance between the adjacent blocks is consistent with the intermittent conveying distance of the conveyor belt.

[0048] The working principle of the above-mentioned intermittent transmission module is as follows: when the transmission length of the intermittent transmission of the conveyor belt is set, the eccentric shaft 730 slides out of the radial groove 711 of the groove wheel 710 and out of the recess on the groove wheel 710. At this time, the main shaft 600 continues to rotate, and the dial wheel 720 cannot drive the groove wheel 710 to rotate, so the gear set 800 and the pulley set 900 are both in a stationary state. In this state, the shaping module shapes the cigarette box; as the main shaft 600 continues to rotate, the dial wheel 720 drives the eccentric shaft 730 to rotate to the position of the next radial groove 711 of the groove wheel 710, thereby driving the groove wheel 710 to rotate again, and this cycle is repeated to realize the intermittent transmission of the intermittent transmission module.

[0049] The grooved wheel mechanism 700 has a simple structure, small dimensions, high mechanical efficiency, and can rotate intermittently relatively smoothly.

[0050] In this embodiment, in order to avoid interference between the sheave 710 and the main shaft 600, a thumbwheel 720 is provided to drive the sheave 710, and an eccentric shaft 730 is provided on the protruding portion of the thumbwheel 720 so that the outer end of the sheave 710 is as far away from the main shaft 600 as possible.

[0051] Of course, in order to avoid interference between the sheave 710 and the main shaft 600 , an avoidance gap may be provided on the main shaft 600 so that the outer end of the sheave 710 passes through the avoidance gap when rotating, thereby realizing the rotation of the sheave 710 .

[0052] In view of the fact that the first conveying assembly 110 and the third conveying assembly 310 in the above-mentioned device are both in automatic conveying mode, the first conveying assembly 110 is driven to drive the cigarette box to move. When the cigarette box reaches the end of the first conveying assembly 110 and enters the second conveying assembly 210, since the second conveying assembly 210 is a stationary conveying track, the conveyance of the cigarette box within the conveying track of the second conveying assembly 210 is completed by its own movement.

[0053] Based on this, a pushing module 400 may be provided on the first side of the first output end 102 (the side opposite to the second side of the first output end 102). The pushing module 400 can move closer to the second starting end 201 or away from the second starting end 201 under the action of the driving mechanism, thereby pushing the cigarette box arriving at the first output end 102 onto the second conveying component 210.

[0054] Specific reference Figure 3As shown, when the cigarette box arrives at the first output end 102 from the first transmission end under the transport of the first conveying assembly 110, the pushing module 400 moves toward the second shaping station 200 under the action of the driving mechanism, that is, it extends above the first conveying assembly 110 to push the cigarette box located at the first output end 102 to the second starting end 201 of the second conveying module. At this time, the cigarette box enters the second shaping station 200, and the pushing module 400 withdraws and returns to the first side of the first output end 102; when the next cigarette box arrives at the first output end 102, the pushing module 400 starts again and pushes the cigarette box toward the second starting end 201 of the second conveying assembly 210. At this time, since the previous cigarette box is located at the second starting end 201, the cigarette box pushed this time pushes the previous cigarette box, and this cycle is repeated until the cigarette box is pushed toward the second output end again and again. When the cigarette box is pushed to the position of the second shaping module 220, the second shaping module 220 shapes it.

[0055] The above-mentioned pushing module 400 is substantially consistent with the pushing structure in the prior art, and can be driven by a driving mechanism such as a motor or a cylinder to perform linear reciprocating motion, which will not be described in detail here.

[0056] In addition, a side of the conveyor belt used for conveying the cigarette box can be provided with a block, and the cigarette box is located between two adjacent blocks; the distance between adjacent blocks is consistent with the intermittent conveying distance of the conveyor belt.

[0057] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
