Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing equipment, in particular to an anti-adhesion leaf-conditioning cylinder for the tobacco industry. Background Art

[0002] In the tobacco industry, feeding and leaf conditioning is an important link connecting the upstream and downstream in the cigarette making production line. It can not only solve the small defects in the previous link, but also provide high-quality and high-stability raw materials for the next link. Appropriate moisture and temperature are the prerequisites for obtaining good leaf structure and internal quality.

[0003] The commonly used leaf conditioning method adopts a drum-shaped leaf conditioner, which includes a leaf-conditioning cylinder. The leaf-conditioning cylinder is installed obliquely. One end of the leaf-conditioning cylinder is the feed inlet, and the other end is the discharge outlet. In the specific leaf conditioning process, tobacco leaves enter the leaf-conditioning cylinder from the feed inlet. The leaf-conditioning cylinder rotates and humidifies the tobacco leaves through a water replenishing device during the flipping process to achieve the leaf conditioning effect. In the prior art, the humidifying method is that water in the water tank is introduced into the leaf-conditioning cylinder through a pipeline; however, this humidifying method is not easy to control. At the same time, during the flipping process of the tobacco in the leaf-conditioning cylinder, due to the addition of water, the tobacco becomes wet, and the tobacco is extremely easy to adhere to the inner wall of the leaf-conditioning cylinder, resulting in uneven flipping of the tobacco and affecting the quality of the tobacco leaves after baking in the later stage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-adhesion leaf-conditioning cylinder for the tobacco industry to solve the problems existing in the background art.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] An anti-adhesion leaf-conditioning cylinder for the tobacco industry includes a rotating assembly and a leaf-conditioning cylinder. A water tank and a hot air blower are arranged on one side of the discharge outlet of the leaf-conditioning cylinder. The water tank is provided with a water pipe, and the hot air blower is provided with a hot air pipe. The hot air pipe is sleeved outside the water pipe. The water pipe and the hot air pipe extend into the leaf-conditioning cylinder and are located at the top inside the leaf-conditioning cylinder. A spray head is arranged on the water pipe inside the leaf-conditioning cylinder. The spray head extends out of the hot air pipe, and the spray head faces the axial direction of the leaf-conditioning cylinder; a hot air spray head is arranged on the hot air pipe inside the leaf-conditioning cylinder, and the hot air spray head faces the top wall direction of the leaf-conditioning cylinder.

[0007] Further, the two ends of the hot air pipe located at the water pipe are of a sealed structure. A sealing ring is arranged at the connection between the spray head and the hot air pipe. One end of the water pipe extending into the leaf-conditioning cylinder is of a sealed structure.

[0008] Further, a plurality of blocking strips are arranged in a circumferential array on the inner wall of the leaf-conditioning cylinder. The connection between the blocking strip and the leaf-conditioning cylinder is of an arc structure, and the cross section of the blocking strip is of a herringbone structure.

[0009] Further, an anti - sticking coating is provided on the inner wall of the leaf conditioning cylinder, and an anti - sticking coating is also provided outside the hot air pipe in the leaf conditioning cylinder.

[0010] Further, a shielding device is provided at the discharge port of the leaf conditioning cylinder. The shielding device includes a bearing, a connecting rod assembly, and a baffle. The bearing is sleeved outside the leaf conditioning cylinder. The inner ring of the bearing is in interference fit with the leaf conditioning cylinder, and the outer ring of the bearing is fixedly connected to the base of the rotating assembly. One end of the connecting rod assembly is connected to the top of the outer ring of the bearing, and the other end of the connecting rod assembly is connected to the baffle.

[0011] Further, a tension spring is provided between the connecting rod group and the outer ring of the bearing.

[0012] Further, the size of the baffle is matched with the size of the discharge port of the leaf conditioning cylinder.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Since the water pipe in the leaf conditioning cylinder is provided with spray nozzles, water mist can be sprayed onto the tobacco in the leaf conditioning cylinder through the spray nozzles, playing a role in moistening the tobacco. At the same time, the hot air pipe in the leaf conditioning cylinder is provided with hot air nozzles, and hot air can be sprayed through the hot air nozzles to heat the tobacco, ensuring the heat in the leaf conditioning cylinder and improving the leaf conditioning effect.

[0015] The spray nozzles face downward and the hot air nozzles face upward. The hot air can always sweep the inner wall of the leaf conditioning cylinder, ensuring that the tobacco attached to the inner wall of the leaf conditioning cylinder is blown, and avoiding the adhesion of tobacco to the inner wall.

[0016] Since the hot air generated by the hot air blower is sprayed out from the hot air nozzles along the hot air pipe, and the water pipe is located in the hot air pipe, the hot air will continuously heat the internal water pipe, making the water mist sprayed from the spray nozzles warm water. And the hot air pipe sleeved outside the water pipe can reduce the occupation of the space in the leaf conditioning cylinder and increase the rolling space of the tobacco.

Detailed implementation mode

[0021] Next, in combination with the embodiments, the technical solutions of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present utility model.

[0022] Refer to Figures 1 - 3 , the present utility model provides a technical solution:

[0023] As Figures 1 - 3 shown, an anti-adhesion leaf conditioning cylinder for the tobacco industry includes a rotating assembly 4 and a leaf conditioning cylinder 3. A water tank 1 and a hot air blower 2 are provided on one side of the discharge port of the leaf conditioning cylinder 3. The water tank 1 is provided with a water pipe 11, and the hot air blower 2 is provided with a hot air pipe 21. The hot air pipe 21 is sleeved outside the water pipe 11. The water pipe 11 and the hot air pipe 21 extend into the leaf conditioning cylinder 3 and are located at the top inside the leaf conditioning cylinder 3. A spray head 12 is provided on the water pipe 11 inside the leaf conditioning cylinder 3. The spray head 12 extends out of the hot air pipe 21, and the spray head 12 faces the axis direction of the leaf conditioning cylinder 3; a hot air spray head 22 is provided on the hot air pipe 21 inside the leaf conditioning cylinder 3, and the hot air spray head 22 faces the top wall direction of the leaf conditioning cylinder 3.

[0024] Through the above technical solution, the water tank 1 and the hot air blower 2 are supported by brackets and are located at one end of the feed port of the leaf conditioning cylinder 3. The hot air pipe 21 of the hot air blower 2 is sleeved outside the water pipe 11 of the water tank 1. The hot air pipe 21 and the water pipe 11 extend into the leaf conditioning cylinder 3 from the feed port together. At this time, the hot air pipe 21 and the water pipe 11 are supported by an external bracket, and the rotation of the leaf conditioning cylinder 3 does not affect the hot air pipe 21 and the water pipe 11.

[0025] Since a spray head 12 is provided on the water pipe 11 inside the leaf conditioning cylinder 3, water mist can be sprayed onto the tobacco inside the leaf conditioning cylinder 3 through the spray head 12 to moisten the tobacco. At the same time, a hot air spray head 22 is provided on the hot air pipe 21 inside the leaf conditioning cylinder 3, and hot air can be sprayed through the hot air spray head 22 to heat the tobacco, ensuring the heat inside the leaf conditioning cylinder 3 and improving the leaf conditioning effect. At the same time, since the spray head 12 faces downward and the hot air spray head 22 faces upward, the hot air can always sweep the inner wall of the leaf conditioning cylinder 3, ensuring that the tobacco attached to the inner wall of the leaf conditioning cylinder 3 is blown and preventing the tobacco from adhering to the inner wall.

[0026] Furthermore, both ends of the hot air pipe 21 located at the water pipe 11 are of a sealed structure. A sealing ring is provided at the connection between the spray head 12 and the hot air pipe 21, and one end of the water pipe 11 extending into the leaf conditioning cylinder 3 is of a sealed structure.

[0027] Through the above technical solution, since the hot air generated by the hot air blower 2 blows out from the hot air nozzle 22 along the hot air pipe 21, and the water pipe 11 is located in the hot air pipe 21, the hot air will continuously heat the internal water pipe 11, making the water mist sprayed from the spray head 12 warm water. The hot air pipe 21 sleeved outside the water pipe 11 can reduce the occupation of the space inside the leaf conditioning cylinder 3 and increase the rolling space of the tobacco.

[0028] Further, a plurality of blocking strips 31 are circumferentially arrayed on the inner wall of the leaf conditioning cylinder 3. The connection between the blocking strip 31 and the leaf conditioning cylinder 3 is an arc structure, and the cross-section of the blocking strip 31 is a herringbone structure.

[0029] Through the above technical solution, when the leaf conditioning cylinder 3 rotates through the rotating assembly 4, the internal tobacco will impact on the blocking strip 31. The blocking strip 31 can play a role in loosening the compacted tobacco leaves. At the same time, the connection between the blocking strip 31 and the leaf conditioning cylinder 3 is an arc structure, and the cross-section of the blocking strip 31 is a herringbone structure, which avoids the tobacco being stuck at the connection between the blocking strip 31 and the inner wall of the leaf conditioning cylinder 3 and improves the leaf conditioning effect.

[0030] Further, an anti-sticking coating is provided on the inner wall of the leaf conditioning cylinder 3, and an anti-sticking coating is also provided outside the hot air pipe 21 inside the leaf conditioning cylinder 3.

[0031] Through the above technical solution, the anti-sticking coating can adopt a PFA anti-sticking coating, which can prevent the tobacco with moisture from directly sticking to the inner wall of the leaf conditioning cylinder 3 and facilitate the subsequent cleaning of the leaf conditioning cylinder 3. At the same time, an anti-sticking coating is also provided outside the hot air pipe 21 inside the leaf conditioning cylinder 3 to prevent the tobacco from adhering to the hot air pipe 21.

[0032] Further, a shielding device 5 is provided at the discharge port of the leaf conditioning cylinder 3. The shielding device 5 includes a bearing 51, a connecting rod assembly 52 and a baffle 54. The bearing 51 is sleeved outside the leaf conditioning cylinder 3. The inner ring of the bearing 51 is in interference fit with the leaf conditioning cylinder 3, and the outer ring of the bearing 51 is fixedly connected to the base of the rotating assembly 4. One end of the connecting rod assembly 52 is connected to the top of the outer ring of the bearing 51, and the other end of the connecting rod assembly 52 is connected to the baffle.

[0033] Further, a tension spring 53 is provided between the connecting rod group and the outer ring of the bearing 51.

[0034] Further, the size of the baffle 54 matches the size of the discharge port of the leaf conditioning cylinder 3.

[0035] Through the above technical solution, since the leaf conditioning cylinder 3 is arranged obliquely downward, during the leaf conditioning process when the leaf conditioning cylinder 3 rotates, some tobacco that has not been properly conditioned by flipping is likely to fall out from one end of the discharge port, affecting the leaf conditioning effect of the tobacco. The bearing 51 and the baffle 54 are connected by the connecting rod assembly 52, and at the same time, the baffle 54 is pulled by the tension spring 53, so that under the elastic force of the tension spring 53, the baffle 54 always buckles on the discharge port of the leaf conditioning cylinder 3 in the initial state, and at this time, the missing tobacco inside cannot push open the baffle 54 and fall out. As the tobacco continues to be put into the leaf conditioning cylinder 3, when the tobacco reaches a certain weight, it will overcome the elastic force of the tension spring 53 and push the baffle 54 out and drop. Therefore, through the baffle 54, it can be ensured that the tobacco can stay in the leaf conditioning cylinder 3 for a longer time, improving the humidifying and heating effects in the leaf conditioning cylinder 3.

[0036] At the same time, since the inner ring of the bearing 51 is in interference fit with the leaf conditioning cylinder 3, and the outer ring of the bearing 51 is fixedly connected to the base of the rotating assembly 4, when the leaf conditioning cylinder 3 rotates, it will not affect the rotation of the baffle 54, and the connecting rod assembly 52 is always located above the leaf conditioning cylinder 3.

[0037] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. And the changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
