Description

Technical Field

[0001] This utility model relates to an additive device, specifically a double-sided spraying and conveying device for tobacco leaves. Background Technology

[0002] With the advancement of tobacco processing technology and the continuous development of re-drying technology, adding flavorings and additives during the re-drying stage has gradually become a trend. Different industrial customers have different additive requirements. In addition to the differences in flavorings and fragrances, the additive processes also vary. Some require additives during the leaf moistening process, while others require additives after drying. However, due to the limited space in tobacco re-drying workshops and the large size and difficulty in moving processing equipment, it is quite difficult to install additive equipment at each process on the existing production line. Moreover, not all tobacco leaves require flavoring or additive treatment. Therefore, there is an urgent need for a small, mobile, and detachable additive device that can be easily placed at the process where additives are needed. To this end, the applicant has applied for a mobile and detachable additive device for re-drying. Although it can be moved and used as needed, it sprays the tobacco leaves while they are in free fall, resulting in a very short spraying time and poor additive effect. Some tobacco leaves are even difficult to spray during the rapid fall. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a double-sided spraying and conveying device for tobacco leaves.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a double-sided spray conveying device for tobacco leaves, comprising a movable frame and a storage tank mounted on the movable frame. The movable frame is also equipped with a liquid pump, the inlet end of which is connected to the bottom of the storage tank. One side of the movable frame is provided with vertically parallel spray pipes, and the opposite sidewalls of the spray pipes are staggered with atomizing nozzles. One end of each spray pipe is connected to the outlet end of the liquid pump. The bottom of the movable frame is provided with moving wheels for pushing the movable frame. The top of the storage tank is provided with a feeding pipe. An electrical control box for controlling the liquid pump is located inside the movable frame. The device also includes a conveyor belt passing through the upper and lower spray pipes. The closed conveyor belt is driven by a reduction motor. The outer surface of the conveyor belt is covered with a layer of mesh cloth. The upper part of the conveyor belt passing between the upper and lower spray pipes is supported and lifted by front and rear support rollers, so that the upper part of the conveyor belt passing between the upper and lower spray pipes is suspended in the air.

[0005] Furthermore, a horizontal water receiving trough is provided below the bottom nozzle, and one side of the water receiving trough is fixedly connected to the fixed rod of the moving frame.

[0006] Furthermore, one end of the nozzle is fixedly connected to the rotary joint, and the other end of the rotary joint is fixedly connected to the liquid outlet of the liquid pump through a hose. The converging part of the nozzle passes through the fixed plate on one side of the moving frame.

[0007] Furthermore, the top of the storage tank is equipped with a cleaning water interface, and the bottom is equipped with an electromagnetic drain valve.

[0008] Furthermore, a flow control valve is installed at the outlet of the liquid pump.

[0009] Furthermore, one of the casters on one side is a swivel caster with a brake.

[0010] Furthermore, the bottom of the storage tank is funnel-shaped, and the bottom of the funnel is connected to the inlet end of the liquid pump.

[0011] With the above configuration, when adding material and spraying tobacco leaves in a certain process, such as adding flavoring, the tobacco leaves are evenly sprinkled on the mesh cloth. The closed conveyor belt is driven by a reduction motor. If this type of conveyor belt is set between two processes, it plays a role in receiving and conveying. Since the upper part of the conveyor belt between the upper and lower spray pipes is supported and lifted by the front and rear support rollers, the upper part of the conveyor belt between the upper and lower spray pipes is suspended in the air. In this way, there is sufficient space on both the upper and lower sides of the conveyor belt. Spray pipes are set on both the upper and lower sides of the conveyor belt between the two support rollers. Atomizing nozzles are arranged alternately on the opposite side walls of the spray pipes. During spraying, liquid material is added and the liquid pump is started. Flavoring is sprayed out from the atomizing nozzles. Because the atomizing nozzles are arranged alternately on the opposite side walls of the spray pipes, and a large area is sprayed during the conveying process, the upper and lower sides of the tobacco leaves passing through this point are evenly and effectively sprayed. The spraying time is more sufficient and comprehensive, effectively avoiding the missed spraying of tobacco leaves, resulting in better material addition, stronger applicability, and better meeting production needs.

[0012] The present invention will now be further described with reference to the accompanying drawings.

[0013] Figure 1 This is a schematic diagram of the main structure of this utility model;

[0014] Figure 2 This is a side view of the nozzle section of this utility model. Detailed Implementation

[0015] like Figure 1-2As shown, a double-sided spray conveying device for tobacco leaves includes a movable frame 1 and a storage tank 2 mounted on the movable frame 1. The movable frame 1 is also equipped with a liquid pump 3, the inlet end of which is connected to the bottom of the storage tank 2. One side of the movable frame 1 is equipped with vertically parallel spray pipes 4, and the opposite sidewalls of the spray pipes 4 are staggered with atomizing nozzles 5. One end of each spray pipe 4 is connected to the outlet end of the liquid pump 3. The bottom of the movable frame 1 is equipped with a moving wheel 6 for pushing the movable frame 1. The top of the storage tank 2 is equipped with a feeding pipe 7. An electrical control box 8 for controlling the liquid pump 3 is located inside the movable frame 1. The device also includes a conveyor belt 9 passing through the upper and lower spray pipes 4. The closed conveyor belt 9 is driven by a reduction motor. The outer surface of the conveyor belt 9 is covered with a layer of mesh fabric 10. The upper part of the conveyor belt 9 passing between the upper and lower spray pipes 4 is supported and lifted by front and rear support rollers 11, so that the upper part of the conveyor belt 9 passing between the upper and lower spray pipes 4 is suspended in the air.

[0016] A horizontal water receiving trough 14 is provided below the bottom nozzle 4. One side of the water receiving trough 14 is fixedly connected to the fixed rod of the moving frame 1. The water receiving trough 14 can catch the excess liquid dripping from the nozzle 4 to prevent it from flowing out, and can be collected and recycled later.

[0017] To facilitate proper adjustment of the tilt angle of the upper and lower nozzles 4, one end of each nozzle 4 is fixedly connected to a rotary joint 12, and the other end of the rotary joint 12 is fixedly connected to the outlet of the liquid pump 3 via a hose. The converging part of the nozzle 4 passes through a fixed plate 13 on one side of the movable frame 1 and can rotate within the fixed plate 13. A cleaning water interface 15 is also provided on the top of the storage tank 2, and an electromagnetic vent valve 16 is provided on the bottom. A flow control valve 17 is provided at the outlet of the liquid pump 3. One of the movable wheels 6 is a universal wheel with a brake. The bottom of the storage tank 2 is funnel-shaped, and the bottom of the funnel-shaped bottom is connected to the inlet of the liquid pump 3.

[0018] The working principle of this utility model is as follows: When it is necessary to add material and spray tobacco leaves in a certain process, such as adding flavoring, the tobacco leaves are evenly sprinkled on the mesh cloth 10. The closed conveyor belt 9 is driven by a reduction motor. If this type of conveyor belt 9 is set between two processes, it plays the role of receiving and conveying. Since the upper part of the conveyor belt 9 passing between the upper and lower spray pipes 4 is supported and lifted by the front and rear support rollers 11, the upper part of the conveyor belt 9 passing between the upper and lower spray pipes 4 is suspended in the air. In this way, there is sufficient space on both the upper and lower sides of the conveyor belt 9. Furthermore, the conveyor belt 9 between the two supporting rollers 11 is equipped with spray pipes 4 on both the top and bottom. The opposite side walls of the spray pipes 4 are staggered with atomizing nozzles 5. During spraying, liquid materials are added and the liquid pump 3 is started. The flavoring is sprayed out from the atomizing nozzles 5. Because the opposite side walls of the spray pipes 4 are staggered with atomizing nozzles 5, and large-area spraying is carried out during the conveying process, the tobacco leaves passing through this area are evenly and effectively sprayed on both the top and bottom. The spraying time is more sufficient and comprehensive, effectively avoiding missed spraying of tobacco leaves, resulting in better feeding effect, stronger applicability, and better meeting production needs.

[0019] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
