Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a sulfuric acid paper conveying device. Background Technology

[0002] Side-opening cigarette packs are a type of irregular cigarette packaging, differing significantly from traditional cigarette packs. The inner lining paper used to package the cigarettes is different from the aluminum foil used in ordinary cigarette packs; it's a special type of tracing paper. This special tracing paper boasts advantages such as high strength, high temperature resistance, air tightness, moisture and oil resistance, maintaining the freshness of the cigarettes and the stability of the packaging, making it widely used in irregular cigarette packaging. However, even in its natural state, this special tracing paper is prone to moisture absorption, curling, and deformation, resulting in poor flatness and stiffness, and it's difficult for it to spring back to a flat state after being rolled.

[0003] Therefore, the traditional conveying method cannot guarantee the flatness of the sulfonate paper during the entire conveying process due to the special characteristics of the side-opening cigarette pack sulfonate paper being easy to curl and having poor flatness. This can easily lead to paper blockage and make it difficult to meet the conveying requirements.

[0004] Therefore, there is an urgent need for a sulfuric acid paper conveying device to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a sulfuric acid paper conveying device for conveying sulfuric acid paper. The conveying process can ensure the good flatness of the sulfuric acid paper, while it is not easy to get clogged and the conveying is smoother.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] As a preferred embodiment of the sulfuric acid paper conveying device, the support assembly includes a bracket, and both the conveying assembly and the smoothing assembly are disposed on the bracket. The bracket is provided with a vacuum channel, which has a negative pressure and is disposed corresponding to the adsorption holes.

[0014] As a preferred embodiment of the sulfuric acid paper conveying device, the support assembly further includes a guide plate disposed on the bracket, the guide plate being provided with a guide groove, the smoothing belt being placed in the guide groove, and the bottom of the guide groove being provided with an air guide hole, the air guide hole being connected to the vacuum channel and the adsorption hole.

[0015] As a preferred embodiment of the sulfuric acid paper conveying device, the sulfuric acid paper conveying device further includes a protective component, the protective component including a fence, the fence being disposed on the support component and spaced apart from the smoothing belt, the sulfuric acid paper being able to pass through the smoothing belt and the fence.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1-5 As shown, this embodiment provides a sulfuric acid paper conveying device for conveying sulfuric acid paper 10. The sulfuric acid paper conveying device includes a support assembly 100, a conveying assembly 200, and a smoothing assembly 300. The conveying assembly 200 is disposed on the support assembly 100 and includes two parallel feed rollers 210. The two feed rollers 210 can rotate synchronously to convey the sulfuric acid paper 10 in a vertically downward conveying direction. The smoothing assembly 300 includes a smoothing roller 310 and a smoothing belt 320 wound around the smoothing roller 310. The smoothing belt 320 extends in the conveying direction. The smoothing roller 310 is used to drive the smoothing belt 320 to rotate in the conveying direction to convey the sulfuric acid paper 10. The smoothing belt 320 is provided with adsorption holes 321 to adsorb the sulfuric acid paper 10.

[0040] By setting up a support assembly 100 to integrate the conveying assembly 200 and the smoothing assembly 300, the conveying and smoothing of the sulfuric acid paper 10 can be achieved. Two feed rollers 210 that rotate synchronously in opposite directions receive the sulfuric acid paper 10 from above and convey it downwards in a vertical direction. The smoothing belt 320 is configured to extend vertically and is provided with adsorption holes 321 that have the ability to adsorb the sulfuric acid paper 10, so that the sulfuric acid paper 10 can be adsorbed onto the smoothing belt 320 after contacting it, and the sulfuric acid paper 10 is conveyed along the conveying direction when the smoothing roller 310 rotates. That is, the smoothing assembly 300 can not only smooth the sulfuric acid paper 10, but also convey it, so that the sulfuric acid paper 10 can have good flatness during the conveying process, and is not easy to clog, ensuring smoother conveying. In addition, the parts of the sulfuric acid paper conveying device are reasonably arranged without interference, can be adapted to existing installation devices, have low production costs, are easier to assemble, and have high use value and economic benefits.

[0041] Specifically, the sulfuric acid paper conveying device also includes a drive assembly 400, which is used to drive the two feed rollers 210 to rotate and to drive the smoothing roller 310 to rotate. That is, the sulfuric acid paper conveying device is equipped with only one drive assembly 400, which realizes the synchronous drive of the conveying assembly 200 and the smoothing assembly 300, simplifies the structure and reduces the cost.

[0042] Furthermore, the drive assembly 400 includes a drive member, a first drive shaft 410, a second drive shaft 420, and a transmission gear set 430. Two feed rollers 210 are respectively disposed on the first drive shaft 410 and the second drive shaft 420. The first drive shaft 410 is located at the output end of the drive member. The transmission gear set 430 includes two gears, respectively disposed on the first drive shaft 410 and the second drive shaft 420. A smoothing roller 310 is disposed on either the first drive shaft 410 or the second drive shaft 420. When the drive member operates, it first drives the first drive shaft 410 to rotate. Due to the meshing of the two gears, the second drive shaft 420 rotates relative to the first drive shaft 410, driving the feed rollers 210 on it to rotate and feed material. Simultaneously, the smoothing roller also rotates, driving the smoothing belt 320 to rotate, thereby conveying the sulfuric acid paper 10 downwards while adsorbing it.

[0043] It is worth noting that the smoothing belt 320 is configured as a synchronous belt, and correspondingly, the smoothing roller 310 is configured as a synchronous pulley, which helps to improve the reliability of conveying the tracing paper 10. In addition, two smoothing components 300 are provided, spaced apart horizontally, to adsorb both sides of the tracing paper 10 in the width direction, resulting in better smoothing and more stable conveying. Optionally, the smoothing component 300 also includes a tension roller 330 for tensioning the smoothing belt 320, ensuring not only reliable engagement between the smoothing belt 320 and the smoothing roller 310, but also ensuring the flatness of the smoothing belt 320, thereby ensuring reliable cooperation between the smoothing belt 320 and the tracing paper 10.

[0044] In this embodiment, the support assembly 100 includes a bracket 110, wherein the first and second conveying shafts of the conveying assembly 200 are rotatably disposed at the upper end of the bracket 110, and the smoothing belt 320 of the smoothing assembly 300 is wrapped around the outside of the bracket 110, with the portion located in front of the bracket 110 used for supporting and conveying the sulfuric acid paper 10. The bracket 110 is not only used for integrated installation and fixation, but its front portion can also provide support and guidance for conveying the sulfuric acid paper 10. To achieve adsorption, the bracket 110 is provided with a vacuum channel 111, which is connected to a negative pressure device through a connector 112 to create a negative pressure within the vacuum channel 111. Since the vacuum channel 111 is connected to the adsorption hole 321, it is used to adsorb the sulfuric acid paper 10.

[0045] Furthermore, the support assembly 100 also includes a guide plate 120 disposed on the bracket 110, the guide plate 120 being bolted to the bracket 110; the guide plate 120 is provided with a guide groove 121, the smoothing belt 320 being placed in the guide groove 121, ensuring stable movement of the smoothing belt 320, thereby ensuring reliable conveying of the sulfuric acid paper 10; the bottom of the guide groove 121 is provided with an air guide hole 122, the air guide hole 122 connecting the vacuum channel 111 and the adsorption hole 321, to ensure that the negative pressure of the vacuum channel 111 can be used to adsorb the sulfuric acid paper 10. It is worth noting that two guide plates 120 and two smoothing belts 320 are provided correspondingly, and the interval between the two guide plates 120 is adapted to the main body width c of the sulfuric acid paper 10.

[0046] Specifically, the sulfuric acid paper conveying device also includes a protective component 500, which includes a fence 510. The fence 510 is disposed on the support component 100 and spaced apart from the smoothing belt 320. That is, the fence 510 is disposed in front of the support component 100. When the smoothing component 300 adsorbs the sulfuric acid paper 10 and moves, the sulfuric acid paper 10 is placed between the smoothing belt 320 and the fence 510, which plays a protective role during the normal conveying process of the sulfuric acid paper 10.

[0047] Preferably, the fence 510 is rotatably connected to the support assembly 100, so that one end of the fence 510 can selectively move away from the support assembly 100. This allows for manual rotation of the fence 510 to facilitate the removal of the waste sulfuric acid paper 10 when it becomes clogged. Correspondingly, the protective assembly 500 is also provided with a locking element 520, which is used to fix the relative position of the fence 510 and the support assembly 100 during the normal conveying of the sulfuric acid paper 10. The protective assembly 500 is also provided with a limiting element 530, which is used to limit the farthest distance that one end of the fence 510 moves away from the support assembly 100, that is, to limit the angle at which the fence 510 rotates open, so as to avoid excessive opening.

[0048] In this embodiment, the conveying assembly 200 is also provided with two parallel and spaced discharge rollers 220. The discharge rollers 220 are located on the support assembly 100 and downstream in the conveying direction. The two discharge rollers 220 rotate relative to each other so that the sulfuric acid paper 10 passing through the feed roller 210 and the smoothing assembly 300 leaves the sulfuric acid paper conveying device from the two discharge rollers 220. By setting the discharge rollers 220, the sulfuric acid paper 10 is received after leaving the smoothing belt 320 position so as to continue to convey the sulfuric acid paper 10 downward.

[0049] Specifically, the rotational speed of the discharge roller 220 is greater than that of the feed roller 210, so that the sulfuric acid paper 10 can leave the sulfuric acid paper conveying device at a speed greater than the conveying speed, thereby reducing the risk of clogging of the sulfuric acid paper 10 and improving the reliability of conveying.

[0050] Preferably, the tracing paper conveying device further includes a guide plate 130, which is disposed on the support assembly 100 and located above the bracket 110 of the conveying assembly 200. The guide plate 130 is provided with a paper guiding slot, through which the tracing paper 10 can pass and enter the conveying device. The guide plate 130 is used to guide the tracing paper 10 so that it can smoothly enter the feed roller 210. It is understood that the dimensions of the guide plate 130 and the bracket 110 are set with reference to the overall width b and length a of the tracing paper 10, and are not specifically limited here.

[0051] The conveying process of the above-mentioned sulfuric acid paper conveying device is as follows: A single sheet of sulfuric acid paper 10 first enters the guide plate 130. When the downward end contacts the feed roller 210, it begins to move downward under the conveying of the feed roller 210, and then continues to adhere tightly to the smoothing belt 320. During this period, airflow enters the vacuum channel 111 of the support 110 from the connector 112, passes through the air guide hole 122, and then to the tightly arranged and regularly ordered adsorption holes 321 on the smoothing belt 320, which firmly adsorb the sulfuric acid paper 10. As the smoothing belt 320 continues to convey downward, when the bottom end of the sulfuric acid paper 10 leaves the adsorption hole 321 and contacts the discharge roller 220, it enters the subsequent device under the conveying of the discharge roller 220. In addition, if the sulfuric acid paper 10 becomes blocked during the conveying process, the gate 510 can be manually opened and rotated at a certain angle to facilitate the removal of the blocked sulfuric acid paper 10.

[0052] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
