Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, specifically a tobacco clip loading and unloading machine. Background Technology

[0002] Tobacco processing involves a series of treatments on harvested tobacco leaves to make them suitable for producing cigarettes and other tobacco products. Tobacco processing includes steps such as tobacco curing, tobacco re-drying, tobacco shredding, and quality inspection. Tobacco curing includes methods such as baking, air-drying, and sun-drying. Baking is a crucial step in flue-cured tobacco processing. Harvested fresh tobacco leaves are stalked and placed in a curing barn. Inside the barn, temperature, humidity, and ventilation are controlled to allow the tobacco leaves to undergo three main stages: yellowing, color fixing, and drying. Air-drying is used for types of tobacco such as Burley tobacco. Harvested tobacco leaves are hung in well-ventilated, appropriately lit drying rooms to dry naturally. During the air-drying process, the chemical components in the tobacco leaves undergo slow changes, forming the unique aroma and flavor of Burley tobacco.

[0003] In current technologies, the tobacco leaf processing method using curing requires workers to clamp fresh tobacco leaves onto supports inside the curing barn. Since most supports inside the curing barn are two-tiered, with the higher tier being higher, workers need to use ladders to clamp the fresh tobacco leaves onto the supports. Furthermore, clamping each support requires moving the ladder, which increases the labor intensity for workers and affects the efficiency of clamping fresh tobacco leaves onto the supports. Therefore, a tobacco clamp loading and unloading machine is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tobacco clamp loading and unloading machine with advantages such as an automatic lifting clamping bracket. It solves the problem that when processing tobacco leaves by baking, workers need to clamp fresh tobacco leaves onto the brackets inside the curing barn. Since most of the brackets inside the curing barn are two-layered, and the higher layer is located at a higher position, workers need to use ladders to clamp the fresh tobacco leaves onto the brackets. Furthermore, clamping each bracket requires moving the ladder, which increases the labor intensity of workers and affects the efficiency of clamping fresh tobacco leaves onto the brackets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tobacco clamp loading and unloading machine, including a tobacco curing barn, a stove is provided on one side of the tobacco curing barn, an air duct and a sealing door are provided on the tobacco curing barn, and a clamping structure is provided inside the tobacco curing barn;

[0006] The clamping structure includes two support frames fixedly installed on the left and right side walls of the inner cavity of the tobacco curing barn. A threaded rod with one end extending through and to the outside is rotatably installed inside each support frame. Support components for supporting the rotation of the threaded rods are provided inside each support frame. Connecting blocks are threaded onto the outer surfaces of both threaded rods. A clamping frame is fixedly installed between opposite sides of the two connecting blocks. A tobacco clamp is slidably installed inside the clamping frame. A feeding component for controlling the movement of the tobacco clamp is installed on the clamping frame. Two drive assemblies are provided on the tobacco curing barn.

[0007] Furthermore, both drive components include a mounting platform fixedly installed on one side of the tobacco curing barn. An asynchronous motor is fixedly installed on the mounting platform. The output shaft of the asynchronous motor passes through and extends into the interior of the tobacco curing barn. A transmission component for driving the threaded rod to rotate is provided outside the output shaft of the asynchronous motor.

[0008] Furthermore, the furnace is fixedly installed on one side of the tobacco curing barn, and the air duct and sealing door are both fixedly installed on the tobacco curing barn.

[0009] Furthermore, both of the supporting components include a circular groove and a bearing. The circular groove is formed on the supporting frame, and the bearing is fixedly installed inside the circular groove. One end of the threaded rod passes through the bearing and is fixedly connected to the inner peripheral wall of the bearing.

[0010] Furthermore, a limiting strip is fixedly installed on the rear side wall of the inner cavity of the two support frames, and a limiting groove is opened on the back of the two connecting blocks. The inner wall of the limiting groove is slidably connected to the outer surface of the limiting strip.

[0011] Furthermore, the tobacco leaf clamp includes a clamping plate and two guide rods. One end of each of the two guide rods is fixedly connected to the back of the clamping plate, and one end of each of the two guide rods passes through the clamping frame and is slidably connected to the clamping frame.

[0012] Furthermore, the feeding component includes a mounting bracket and an electric push rod. The electric push rod is fixedly mounted on the mounting bracket, and the mounting bracket is fixedly mounted on the back of the clamping frame. The telescopic end of the electric push rod passes through the clamping frame and is fixedly connected to the back of the clamping plate.

[0013] Furthermore, each of the two transmission components includes two bevel gears, the outer surfaces of the two bevel gears meshing with each other, and the two bevel gears are respectively fixedly installed on the outer surfaces of the asynchronous motor output shaft and the threaded rod.

[0014] Furthermore, displacement sensors are fixedly installed on opposite sides of the two connecting blocks, and the two displacement sensors are electrically connected to the two asynchronous motors respectively.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This tobacco clamp loading and unloading machine, equipped with a clamping structure, enables rapid up-and-down movement of the clamping frame via an asynchronous motor-driven threaded rod. This allows for height adjustment of the clamping frame, facilitating tobacco clamping operations. Furthermore, the loading and unloading actions are controlled by an electric push rod, resulting in a high degree of automation. Compared to traditional manual methods, this significantly improves loading and unloading efficiency, saving time and labor costs. The electrical connection between a displacement sensor and the asynchronous motor allows for precise control of the clamping frame's position, ensuring the clamps are at the appropriate height for loading and unloading, improving accuracy and stability, and reducing errors caused by positional deviations. This enhances the machine's practicality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4The tobacco clamp loading and unloading machine in this embodiment includes a tobacco curing barn 1, a stove 2 is provided on one side of the tobacco curing barn 1, an air duct 3 and a sealing door 4 are provided on the tobacco curing barn 1, and a clamping structure is provided inside the tobacco curing barn 1. The stove 2 is fixedly installed on one side of the tobacco curing barn 1, and the air duct 3 and the sealing door 4 are both fixedly installed on the tobacco curing barn 1.

[0024] Example 1: Please refer to Figures 1 to 4 In this embodiment, the clamping structure includes two support frames 51, respectively fixedly installed on the left and right side walls of the inner cavity of the tobacco curing barn 1. A threaded rod 52, with one end extending through and to the outside, is rotatably installed inside each support frame 51. Each support frame 51 has a support component 53 for supporting the rotation of the threaded rod 52. Each support component 53 includes a circular groove and a bearing. The circular groove is formed on the support frame 51, and the bearing is fixedly installed inside the circular groove. One end of the threaded rod 52 passes through the bearing and is fixedly connected to the inner circumferential wall of the bearing, facilitating the use of the bearing to support the rotation of the threaded rod 52 and reducing rotational speed. Friction is used to prevent the connecting blocks 54 from being threaded onto the outer surfaces of the two threaded rods 52. Limiting strips are fixedly installed on the rear side walls of the inner cavities of the two support frames 51. Limiting grooves are opened on the back of the two connecting blocks 54. The inner wall of the limiting groove is slidably connected to the outer surface of the limiting strip, so as to restrict the connecting blocks 54 to only make linear movements on the outer surface of the limiting strip. A clamping frame 55 is fixedly installed between the opposite sides of the two connecting blocks 54. A tobacco leaf clamp 56 is slidably installed inside the clamping frame 55. A feeding component 57 for controlling the movement of the tobacco leaf clamp 56 is installed on the clamping frame 55. Two drive components are provided on the tobacco curing barn 1.

[0025] The tobacco leaf clamp 56 includes a clamping plate and two guide rods. One end of each guide rod is fixedly connected to the back of the clamping plate. One end of each guide rod passes through the clamping frame 55 and is slidably connected to the clamping frame 55, which facilitates the stable back-and-forth movement of the clamping plate inside the clamping frame 55.

[0026] In addition, the feeding component 57 includes a mounting bracket and an electric push rod. The electric push rod is fixedly mounted on the mounting bracket and fixedly mounted on the back of the clamping frame 55. The telescopic end of the electric push rod passes through the clamping frame 55 and is fixedly connected to the back of the clamping plate, so as to facilitate the movement of the clamping plate back and forth by telescopic movement of the electric push rod.

[0027] By adopting the above technical solution, when the threaded rod 52 rotates, the connecting block 54 is threadedly connected to the threaded rod 52, and the limiting groove on the back of the connecting block 54 is slidably connected to the limiting strip on the rear side wall of the inner cavity of the support frame 51, which restricts the rotation of the connecting block 54. This allows the connecting block 54 to move downwards along the threaded rod 52, causing the connecting block 54 to drive the clamping frame 55 to move synchronously, thereby adjusting the height position of the clamping frame 55 in the tobacco curing barn 1, thus facilitating the work of clamping tobacco leaves for the staff. When the clamping frame 55 moves to the appropriate position, the electric push rod of the feeding component 57 is activated. The telescopic end of the electric push rod pushes the clamping plate, and the clamping plate slides in the clamping frame 55 through the guide rod, realizing the extension or retraction of the tobacco leaf clamp 56, and completing the clamping or unloading operation of the tobacco leaves.

[0028] Example 2: Please refer to Figures 1 to 4 In this embodiment, both drive components include a mounting platform 58 fixedly installed on one side of the tobacco curing barn 1. An asynchronous motor 59 is fixedly installed on the mounting platform 58. The output shaft of the asynchronous motor 59 passes through and extends into the interior of the tobacco curing barn 1. A transmission component 60 for driving the threaded rod 52 to rotate is provided outside the output shaft of the asynchronous motor 59. Both transmission components 60 include two bevel gears. The outer surfaces of the two bevel gears mesh with each other. The two bevel gears are fixedly installed on the outer surfaces of the output shaft of the asynchronous motor 59 and the threaded rod 52, respectively, so that the rotating output shaft can drive the threaded rod 52 to rotate through the two bevel gears.

[0029] Displacement sensors are fixedly installed on opposite sides of the two connecting blocks 54. The two displacement sensors are electrically connected to the two asynchronous motors 59 respectively, which facilitates real-time monitoring of the position of the connecting blocks 54 and timely triggering to stop the asynchronous motors 59.

[0030] Using the above technical solution, the asynchronous motor 59 installed on the mounting platform 58 is started, the output shaft of the asynchronous motor 59 begins to rotate, and the bevel gear on the output shaft of the asynchronous motor 59 rotates with the output shaft. Since the bevel gear meshes with another bevel gear fixed on the outer surface of the threaded rod 52, the threaded rod 52 is driven to rotate within the support frame 51.

[0031] The working principle of the above embodiments is as follows:

[0032] When the cigarette clip loading and unloading machine is in use, the asynchronous motor 59 installed on the mounting platform 58 is started, the output shaft of the asynchronous motor 59 begins to rotate, and the bevel gear on the output shaft of the asynchronous motor 59 rotates with the output shaft. Since the bevel gear meshes with another bevel gear fixed on the outer surface of the threaded rod 52, it drives the threaded rod 52 to rotate within the support frame 51.

[0033] When the threaded rod 52 rotates, the connecting block 54 is threadedly connected to the threaded rod 52, and the limiting groove on the back of the connecting block 54 is slidably connected to the limiting strip on the rear side wall of the inner cavity of the support frame 51, which restricts the rotation of the connecting block 54. This allows the connecting block 54 to move downward along the threaded rod 52, which in turn causes the clamping frame 55 to move synchronously, thereby adjusting the height of the clamping frame 55 in the tobacco curing barn 1, thus facilitating the work of the staff in clamping tobacco leaves.

[0034] Once the clamping frame 55 is moved to the appropriate position, the electric push rod of the feeding component 57 is activated. The telescopic end of the electric push rod pushes the clamping plate, which slides within the clamping frame 55 via the guide rod, thereby extending or retracting the tobacco clamp 56 and completing the clamping or unloading operation of the tobacco leaves.
