Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and in particular to a structure for a tobacco pack conveying channel. Background Technology

[0002] The cigarette packs produced by the main unit of the cigarette packaging machine are conveyed to the auxiliary machine (downstream equipment) through the conveyor channel to complete the subsequent packaging operation. The cigarette pack conveyor channel turns the cigarette packs through the turning conveyor box, and the conveyor belt achieves the conveying of the cigarette packs through friction.

[0003] The existing tobacco pack conveyor steering device uses a belt to turn the tobacco packs from straight to horizontal movement and then conveys them to the auxiliary machine. Due to its special location at the turning point, its disassembly and installation process is relatively complicated. The belt can be installed in the following two ways:

[0004] 1. Remove the connecting parts between the steering box and the channel, or the side wall of the steering channel (some modifications make the side wall detachable), and then put the fully formed belt onto the power roller.

[0005] 2. First, thread the belt onto the power roller, and then bond the belt joint.

[0006] The above methods have several problems: disassembling and assembling connectors and sidewalls, then installing the belt, or handling and bonding joints, all require at least 30 minutes, which is time-consuming and involves a significant amount of work. Furthermore, if the transmission housing's conveyor rollers, transmission gears, or bearings are damaged, disassembling and assembling the steering housing and replacing the corresponding spare parts will take even longer. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a cigarette pack conveying channel structure to solve the problems of long installation and disassembly time, large workload and low efficiency of the existing devices mentioned in the background art.

[0008] The present invention solves the above-mentioned technical problems through the following technical means:

[0009] A cigarette pack conveying channel structure includes a first box, a second box, and a transition assembly. The transition assembly includes a third box and a fourth box, which are fixedly connected. A first conveyor belt is tensioned between the third box and the fourth box. A first transition component is provided between the third box and the first box, and a second transition component is provided between the fourth box and the second box. A second conveyor belt is tensioned on the first box, and a third conveyor belt is tensioned on the second box. One side of the first box has a mounting groove. Transmission components are provided on the first box, the second box, the third box, and the fourth box. Connecting components are provided between the transmission components of the first box and the third box, the fourth box, and the second box.

[0010] Furthermore, the first and second transition components have identical structures. The first transition component includes a transition plate and a transition roller. The transition plate is fixedly installed between the first and third housings, and a groove is formed on the transition plate. The transition roller is rotatably installed within the groove. With this configuration, when the device is operating, the cigarette packs slide from the second conveyor belt onto the transition plate via friction and inertia, and then slide onto the first conveyor belt via friction and inertia, achieving a turning effect in the transport of the cigarette packs. Simultaneously, the transition roller makes the sliding of the cigarette packs smoother.

[0011] Furthermore, the transition plate is fan-shaped. This arrangement conforms to the positional relationship where the first and third housings are installed at a certain angle.

[0012] Furthermore, the transition plate has a trapezoidal cross-section. This inclined design allows the cigarette packs on the first conveyor belt to slide more smoothly into and out of the transition plate.

[0013] Furthermore, the tops of the first conveyor belt, second conveyor belt, third conveyor belt, transition plate, and transition roller are all at the same horizontal plane. This arrangement prevents the tobacco packs from sliding on uneven surfaces by keeping their overall tops at the same horizontal plane.

[0014] Furthermore, each of the aforementioned transmission components has an identical structure, comprising a pulley shaft, a first roller shaft, and a second roller shaft. The pulley shaft, first roller shaft, and second roller shaft of the transmission component on the first housing are all rotatably mounted on the first housing. A transmission wheel passes through the pulley shaft, a first belt roller passes through the first roller shaft, and a second belt roller passes through the second roller shaft. The first belt roller, second belt roller, and transmission wheel are all in contact with the second conveyor belt. This configuration is used to drive the conveyor belt while simultaneously limiting the shape of the second conveyor belt through the pulley shaft, the first belt roller, and the second belt roller.

[0015] Furthermore, the two connecting components have identical structures, each including a first bevel gear and a second bevel gear. A transition gear meshes with one side of the first bevel gear, and the second bevel gear meshes with one side of the transition gear. This configuration ensures that when the first bevel gear rotates, the transition gear drives the second bevel gear to rotate, and simultaneously, the transition gear ensures that the first and second bevel gears rotate in the same direction.

[0016] Furthermore, the first bevel gear is fixedly connected to the pulley shaft of the first housing, and the second bevel gear is fixedly connected to the pulley shaft of the third housing. With this configuration, when the device is operating, the pulley shaft of the first housing rotates, driving the first bevel gear to rotate. The first bevel gear, through an intermediate gear, drives the second bevel gear to rotate, and the second bevel gear then drives the pulley shaft of the third housing to rotate, thus achieving the effect of driving the first conveyor belt to rotate.

[0017] Furthermore, the first, second, third, and fourth housings have identical structures. This design achieves modularity, reduces production costs, and facilitates replacement.

[0018] The present invention has the following advantages:

[0019] 1. The third and fourth boxes are fixedly connected by bolts. The first and third boxes are fixedly installed at a certain angle, and the second and fourth boxes are fixedly installed at a certain angle, so as to achieve the effect of turning the tobacco pack conveying channel and facilitate the conveying of tobacco packs.

[0020] 2. Through the cooperation of the first housing, second housing, third housing, fourth housing, transmission components, transition components and connecting components, the device achieves modularity, reduces production costs and facilitates replacement;

[0021] 3. The sides of the first, second, third, and fourth housings are all designed to be open, meaning that the first, second, and third conveyor belts can be installed without disassembling the first, second, third, and fourth housings via the mounting slots. This solves the problems of long installation and disassembly times, large workload, and low efficiency in existing devices.

[0022] 4. Power is transmitted through the pulley shaft, transmission wheel, first bevel gear, transition gear, and second bevel gear. When the pulley shaft of the first housing rotates, it drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate through the transition gear. The second bevel gear then drives the pulley shaft of the third housing to rotate. The power transmission principle between the fourth housing and the second housing is the same. This achieves the purpose of driving the first and third conveyor belts through the second conveyor belt, which facilitates the transportation of cigarette packs. Attached Figure Description

[0028] like Figure 1As shown, a cigarette pack conveying channel structure of the present invention includes a first housing 1, a second housing 2, a transition assembly, and a base plate. The transition assembly includes a third housing 3 and a fourth housing 4. In this embodiment, the bottoms of the first housing 1, the second housing 2, the third housing 3, and the fourth housing 4 all have mounting holes. The first housing 1, the second housing 2, the third housing 3, and the fourth housing 4 are all fixedly connected to the base plate by bolts, achieving the effect of quick installation and disassembly of the first housing 1, the second housing 2, the third housing 3, and the fourth housing 4. In this embodiment, the first housing 1, the second housing 2, the third housing 3, and the fourth housing 4 have the same structure, and each of the first housing 1, the second housing 2, the third housing 3, and the fourth housing 4 is provided with a transmission component. Each transmission component has the same structure, achieving the effect of modularization of the device, reducing production costs, and facilitating replacement. In this embodiment, the third box 3 and the fourth box 4 are fixedly connected by bolts. The first box 1 and the third box 3 are fixedly installed on the base plate at a certain angle by bolts. The second box 2 and the fourth box 4 are fixedly installed on the base plate at a certain angle by bolts, so as to achieve the effect of turning the tobacco pack conveying channel and facilitate the conveying of tobacco packs.

[0029] like Figure 1-2 As shown, in this embodiment, the transmission assembly on the first housing 1 is used as an example for explanation. The transmission assembly includes a pulley shaft 12, a first roller shaft 13, and a second roller shaft 18. The pulley shaft 12 is rotatably mounted on the right side of the first housing 1, the first roller shaft 13 and the second roller shaft 18 are both rotatably mounted on the left side of the first housing 1, and the second roller shaft 18 is rotatably mounted below the first roller shaft 13. A transmission wheel 121 is fixedly threaded through the pulley shaft 12, a first belt roller 131 is fixedly threaded through the first roller shaft 13, and a second belt roller 181 is fixedly threaded through the second roller shaft 18. A power source is provided on one side of the first housing 1, and a second conveyor belt 11 is tensioned between the power source and the first housing 1. When the device is working, the power source is started, driving the second conveyor belt 11 to rotate. The rotation of the second conveyor belt 11 then drives the transmission wheel 121, the first belt roller 131, and the second belt roller 181 to rotate, thereby driving the pulley shaft 12 to rotate through the transmission wheel 121. (Reference) Figure 2 In this embodiment, the first belt roller 131, the second belt roller 181 and the conveyor wheel 121 are all in contact with the second conveyor belt 11, and the shape of the second conveyor belt 11 is restricted by the first belt roller 131, the second belt roller 181 and the conveyor wheel 121.

[0030] like Figure 2As shown, in this embodiment, the first housing 1 is used as an example for explanation. The pulley shaft 12, the first roller shaft 13, and the second roller shaft 18 are all clamped with bearings 14 between them and the first housing 1. This is used to reduce wear between the pulley shaft 12, the first roller shaft 13, or the second roller shaft 18 and the first housing 1, thereby protecting the pulley shaft 12, the first roller shaft 13, the second roller shaft 18, and the first housing 1.

[0031] like Figure 2 As shown, in this embodiment, the first box 1 is used as an example for explanation. The first box 1 includes a main box 15, an upper support plate 16 and a lower support plate 17. The upper support plate 16 and the lower support plate 17 are both fixedly connected to the main box 15 by bolts. During processing and production, the first box 1 is divided into three parts: the main box 15, the upper support plate 16 and the lower support plate 17, to facilitate processing and reduce processing costs.

[0032] like Figure 1-2 As shown, in this embodiment, the first housing 1 is used as an example for explanation. The side of the first housing 1 is designed to be open, that is, the main housing 15, the upper support plate 16 and the lower support plate 17 form an installation groove 19 for installing the second conveyor belt 11. This achieves the effect of installing the second conveyor belt 11 without disassembling the first housing 1, which solves the problem that the existing device takes a long time to install and disassemble, and has a large workload and low efficiency.

[0033] like Figure 1 As shown, a connecting component 5 is provided between the transmission components of the first housing 1, the third housing 3, the fourth housing 4, and the second housing 2. In this embodiment, the two connecting components 5 have the same structure. The connecting component 5 includes a first bevel gear 51 and a second bevel gear 53. A transition gear 52 meshes with one side of the first bevel gear 51, and the second bevel gear 53 meshes with the right side of the transition gear 52. The first bevel gear 51 and the second bevel gear 53 rotate in the same direction through the transition gear 52. Taking one of the connecting components 5 as an example, the first bevel gear 51 is fixedly connected to the pulley shaft 12 of the first housing 1 by a spline, and the second bevel gear 53 is fixedly connected to the pulley shaft 12 of the third housing 3 by a spline. The first conveyor belt 31 is tensioned between the third housing 3 and the fourth housing 4. When the device is working, the pulley shaft 12 of the first housing 1 rotates, which drives the first bevel gear 51 to rotate. The first bevel gear 51 drives the second bevel gear 53 to rotate through the transition gear 52. The second bevel gear 53 then drives the pulley shaft 12 of the third housing 3 to rotate, thus achieving the effect of driving the first conveyor belt 31 to rotate.

[0034] like Figure 1As shown, in this embodiment, there are preferably two connecting components 5, which are respectively set between the fourth box 4 and the second box 2, and between the third box 3 and the first box 1, so as to connect the third box 3 and the first box 1, the fourth box 4 and the second box 2, and connect them into a whole, which facilitates the transportation of cigarette packs.

[0035] like Figure 1-2 As shown, a first transition component 6 is provided between the third housing 3 and the first housing 1, and a second transition component 7 is provided between the fourth housing 4 and the second housing 2. In this embodiment, the first transition component 6 and the second transition component 7 have the same structure, achieving a modular effect, reducing production costs, and facilitating replacement.

[0036] like Figure 1-2 As shown, in this embodiment, the first transition component 6 is used as an example for explanation. The first transition component 6 includes a transition plate 61 and a transition roller 62. The transition plate 61 is fixedly installed between the first housing 1 and the third housing 3, and is in contact with the first conveyor belt 31 and the second conveyor belt 11. A groove is provided on the transition plate 61, and the transition roller 62 is rotatably installed in the groove. Preferably, there are two grooves and two transition rollers 62. When the device is working, the cigarette pack slides from the second conveyor belt 11 into the transition plate 61 by friction and inertia, and then slides into the first conveyor belt 31 by friction and inertia, realizing the transportation and turning effect of the cigarette pack; at the same time, the transition roller 62 makes the cigarette pack slide more smoothly. In this embodiment, the transverse cross-section of the transition plate 61 is trapezoidal. The tops of the first conveyor belt 31, the second conveyor belt 11, the transition plate 61, and the transition roller 62 are all on the same horizontal plane. The inclined arrangement allows the cigarette packs on the second conveyor belt 11 to slide more smoothly into and out of the transition plate 61. By keeping the tops of the entire assembly on the same horizontal plane, the unevenness of the sliding path of the cigarette packs is prevented from affecting the sliding effect. In this embodiment, the transition plate 61 is fan-shaped, which conforms to the positional relationship of the first housing 1 and the third housing 3 being installed at a certain angle.

[0037] In this embodiment, an auxiliary machine is fixedly installed on one side of the second housing 2, and a third conveyor belt 21 is tensioned between the second housing 2 and the auxiliary machine to achieve the purpose of transporting the cigarette pack to the auxiliary machine, that is, to complete the transport of the cigarette pack.

[0038] The installation and usage method of this invention is as follows:

[0039] During installation, the third box 3 and the fourth box 4 are first fixedly connected by bolts. Then, the first box 1 and the third box 3 are fixedly installed at a certain angle by bolts. The second box 2 and the fourth box 4 are also fixedly installed at a certain angle, achieving the effect of a turning point in the cigarette pack conveying channel, which facilitates the conveying of cigarette packs.

[0040] In fact, by using the mounting slot 19, the installation of the first conveyor belt 31, the second conveyor belt 11, and the third conveyor belt 21 can be completed without disassembling the first box 1, the second box 2, the third box 3, and the fourth box 4, thus solving the problem that the existing device is time-consuming, labor-intensive, and inefficient during installation and disassembly.

[0041] Finally, the transition plate 61 is fixedly installed between the first box 1 and the third box 3, and the second box 2 and the fourth box 4, so as to connect the first box 1 and the third box 3, and the second box 2 and the fourth box 4, so that the cigarette pack can slide from the second conveyor belt 11 into the first conveyor belt 31, and then from the first conveyor belt 31 into the third conveyor belt 21, and finally slide onto the auxiliary machine to complete the conveying of the cigarette pack.

[0042] The power transmission between the first housing 1 and the third housing 3 is achieved through the fixed connection of the first bevel gear 51 to the pulley shaft 12 of the first housing 1, the meshing of the first bevel gear 51 with the transition gear 52, the meshing of the transition gear 52 with the second bevel gear 53, and the fixed connection of the second bevel gear 53 to the pulley shaft 12 of the third housing 3. When the pulley shaft 12 of the first housing 1 rotates, it drives the first bevel gear 51 to rotate. The first bevel gear 51 drives the second bevel gear 53 to rotate through the transition gear 52, and the second bevel gear 53 then drives the pulley shaft 12 of the third housing 3 to rotate. The power transmission principle between the fourth housing 4 and the second housing 2 is the same, which achieves the purpose of driving the first conveyor belt 31 and the third conveyor belt 21 through the second conveyor belt 11, which facilitates the transportation of cigarette packs.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
