Description

Technical Field

[0001] This utility model relates to the field of tobacco technology, specifically a tobacco drying rack. Background Art

[0002] During tobacco processing, it is necessary to remove internal impurities and moisture, usually through curing. Existing tobacco curing racks are mostly single-height frame structures, making it difficult to adjust the curing height to accommodate different types of tobacco leaves. Therefore, designing a new type of tobacco curing rack is crucial, for example:

[0003] A tobacco drying rack for tobacco drying, with Chinese patent authorization announcement number CN213369879U, includes an oven. Inside the oven is a tobacco storage box, which comprises a rectangular frame. Both ends of the rectangular frame are fixed with rotating shafts that are rotatably inserted into the inner wall of the oven. A steel wire base plate is fixed inside the rectangular frame. A steel wire cover plate is hinged to the top of the rectangular frame. An L-shaped locking block is fixed to one end of the steel wire cover plate. A bolt passes through the side of the locking block and is inserted into the side of the rectangular frame, with the bolt and the rectangular frame connected by threads. One end of the rotating shaft extends out of the oven and is fixedly fitted with a second sprocket. A motor is installed on the side of the oven, and a first sprocket is fixedly fitted onto the output shaft of the motor.

[0004] However, the above-mentioned existing technical solutions have the following drawbacks: they are not convenient for positioning the tobacco leaves on the baking rack, and it is difficult to avoid the positional deviation of the tobacco leaves during the baking process. At the same time, it is not convenient to adjust the baking height of the tobacco leaves on the baking rack. Therefore, this utility model provides a tobacco leaf baking rack to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a tobacco curing rack to solve the problems mentioned in the background art, such as the inconvenience of positioning the tobacco leaves, the difficulty in avoiding positional displacement during the curing process, and the inconvenience of adjusting the curing height of the tobacco leaves.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tobacco drying rack, comprising a base, a support frame at the bottom of the base, a heat insulation pad installed inside the base, a drying tube disposed on the upper side of the heat insulation pad, a connector installed on the front side of the drying tube, a perforated mesh disposed on the inner side of the base, a protective cover disposed on the upper side of the base, and a connecting bolt connected to the inner side of the protective cover.

[0007] A connecting seat is provided on the outside of the connecting bolt, and a limit rod is installed on the inside of the connecting seat. A motor is provided on the upper side of the protective cover, and a drive rod is connected to the lower end of the motor. A drive block is provided on the outside of the drive rod, and a first positioning plate is provided on the inside of the drive block. A first positioning net is installed inside the first positioning plate, and a positioning assembly is provided at the bottom of the first positioning net. The positioning assembly includes a first positioning block provided on the lower side of the first positioning net.

[0008] The second positioning block is located inside the first positioning block, and a connecting bolt is connected to the outside of the first positioning block. The lower end of the second positioning block is provided with a second positioning plate, and a second positioning mesh is installed inside the second positioning plate.

[0009] Preferably, the baking tubes are U-shaped and are evenly spaced on the heat insulation pad.

[0010] Preferably, the connector is engaged with the heat insulation pad, and the connector is in the shape of an "I" and is symmetrically arranged about the center line of the baking tube.

[0011] Preferably, the connecting bolt and the connecting seat are threadedly connected, and the connecting bolt is set at an equal angle about the center of the connecting seat, and the connecting seat is symmetrically arranged above and below the center line of the limiting rod.

[0012] Preferably, the drive rod extends through the interior of the drive block, and the drive block and the limiting rod are slidably connected relative to each other.

[0013] Preferably, the first positioning block and the second positioning block are engaged and connected, and the connecting bolts are set at equal intervals on the second positioning block.

[0014] Preferably, the connecting bolt is threaded to both the first positioning block and the second positioning block, and the connecting bolt is symmetrically arranged about the center line of the second positioning block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This tobacco drying rack, by adding a positioning assembly and a second positioning net, ensures that after the connecting bolt is tightened, the tobacco leaves to be dried are confined inside the cavity formed by the first positioning plate and the second positioning net. Compared with the traditional technology, it is easier for the drying rack to position the tobacco leaves and avoid their position shift during the drying process. At the same time, the addition of a motor and a limiting rod makes it easy to adjust the drying height of the tobacco leaves. The specific operation is as follows:

[0016] 1. It is equipped with a connecting bolt and a connecting seat. The connecting bolt and the connecting seat are connected by a threaded connection. The connecting bolt is set at an equal angle with respect to the center of the connecting seat. The connecting seat is symmetrically set above and below the center line of the limit rod. After tightening the connecting bolt, it is easy to improve the stability when adjusting the baking height.

[0017] 2. Equipped with a motor and a limit rod, the motor drives the drive rod to rotate when the motor is turned on. The threaded structure on the outside of the drive rod drives the drive block to move, so that the drive block and the limit rod are slidably connected. At this time, the vertical height of the second positioning net and the tobacco leaves placed inside is changed with respect to the baking tube, which makes it easier to adjust the baking height of the tobacco leaves by the baking rack.

[0018] 3. It is equipped with a positioning assembly and a baking tube. The second positioning block at the upper end of the second positioning plate engages with the first positioning block at the lower end of the first positioning plate. The connecting bolt is tightened so that the second positioning block and the first positioning block are connected by the connecting bolt. This facilitates the positioning of the tobacco leaves by the baking rack and prevents them from shifting during the baking process. Attached Figure Description
