Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, specifically to a storage cabinet anti-mixing control device. Background Technology

[0002] In the cigarette manufacturing process, storage equipment (including pre-mixing cabinets, leaf storage cabinets, shredded tobacco storage cabinets, and blending cabinets) is a key process device used for temporary storage and regulation of materials. This type of equipment is typically located between different processing stages to store processed tobacco leaves or shredded tobacco, and to achieve temperature and humidity balance of the materials and coordination of the cycle time between preceding and following processes, thereby ensuring the continuity and stability of the cigarette manufacturing process.

[0003] Existing storage tank equipment typically includes a tank body, a feeding mechanism, a discharging mechanism, and a conveyor belt. The tank body is used to hold materials. The feeding mechanism often uses a mobile feeding trolley, combined with photoelectric sensors to achieve dynamic detection of material height and automatic feeding control. The discharging mechanism is generally located at the discharge end and mainly consists of a bottom belt conveyor, a feeding roller, and a discharge hood. The bottom belt conveyor is used to transport the material in the storage tank to the discharge end; the feeding roller is located above the tail end of the bottom belt conveyor and is used to break up and loosen the conveyed tobacco; the discharge hood is located below the feeding roller and guides the material from the storage tank to the common discharge conveyor belt below.

[0004] To save workshop space, reduce equipment configuration and wiring costs of the conveying system, and improve the centralized management efficiency of the material conveying process, the discharge ends of multiple storage tanks are usually designed to share a single discharge conveyor belt, which transports materials to subsequent processes such as re-drying, flavoring, or silk feeding through a unified channel.

[0005] However, under the above structural layout, in actual use, when one storage tank is discharging, if an adjacent storage tank is feeding, due to localized high-level accumulation of material near the discharge port during feeding, some material may accidentally slide down to its own discharge hood area due to gravity or slippage of the inner wall, and then fall into the shared conveyor belt. This unplanned material falling will cause mixing of materials between different storage tanks, compromising the independence of material batches and the consistency of the formula, thereby leading to quality incidents. This application is proposed to solve the above problems. Utility Model Content

[0006] The technical solution adopted in this utility model is as follows:

[0007] A storage tank anti-mixing control device is provided, installed at the discharge end of the storage tank. The device includes a housing 1, with an elongated hole 2 communicating with the inner cavity on the lower end face of the housing 1; fixed seats 3 are provided on the front and rear outer walls of the housing 1; a motor 4 is provided on the right side of the front wall of the housing 1; two rotating rods 6 are rotatably connected to the front and rear inner walls of the housing 1 through two sets of bearings 5, and the front end of one of the rotating rods 6 is fixedly connected to the output end of the motor 4 through a coupling; a gear 7 is interference-fitted to the outer wall of each rotating rod 6, and a rotating cylinder 8 is fixedly connected to the outer peripheral wall of the rotating rod 6 in front of the gear 7.

[0008] Preferably, the material blocking device includes a connecting plate 9 and a baffle 10. The connecting plate 9 is installed on the outer wall of the rotating drum 8, and its bottom end extends downward through the elongated hole 2 to the outside of the housing 1.

[0011] Preferably, the two gears 7 are meshed together.

[0012] This utility model provides a storage tank anti-mixing control device, which is installed upstream of the storage tank outlet. It addresses the potential material mixing problem caused by multiple storage tanks sharing a single discharge conveyor belt, and has the following beneficial effects:

[0013] 1. The present invention has an active material blocking structure set up upstream of the discharge port of the storage tank, which can form an effective barrier in the non-discharge state to prevent materials such as tobacco from accidentally falling into the discharge channel due to the accumulation of feed or the slippage of its own weight, thus preventing the mixing of materials between different storage tanks from the source and ensuring the consistency of product formula and quality stability.

[0014] 2. The device adopts a motor-driven rotating rod structure, which links two rotating drums through meshing gears to achieve synchronous flipping of the front and rear baffles. With the help of the control system, it can realize automatic opening and closing in conjunction with the material discharge action, thereby improving control accuracy and operational stability.

[0015] 3. The device is installed in the form of a shell module above the discharge end of the storage tank. The structure is reasonable and can be seamlessly connected with the existing discharge system. It does not require large-scale modification of the original equipment, which facilitates installation, commissioning and later maintenance, and has good engineering application value.

[0016] 4. The material blocking device is set on the outer wall of two synchronously rotating drums, which drives two vertically symmetrically arranged baffles to flip and control the discharge channel, effectively blocking the accidental material falling in the front and rear directions on both sides, and improving the coverage and reliability of the interception.

[0017] 5. The device is fixed to the inner wall of the storage tank by welding or bolting, making installation simple and quick. Operators only need to control the opening and closing of the baffle by rotating the motor forward and backward to receive the wire and discharge it normally. Operation is simple and easy to master, requiring no complex training or additional manpower, significantly improving on-site operational efficiency and safety. The device is mainly composed of conventional mechanical parts, making it easy to manufacture and offering advantages such as low cost and stable performance. It is easy to quickly deploy and apply to multiple storage tanks, making it suitable for large-scale industrial production. Attached Figure Description

[0029] One specific application of this embodiment is:

[0030] In use, this device is installed on the inner wall of the discharge end of the storage tank by welding or bolt fastening through the fixed base (3), and is located upstream of the discharge port. The baffle (10) is set on the inner side wall of the discharge port of the storage tank. The motor (4) drives the rotating rod (6) to rotate. The rotating rod (6) drives the interference fit gear (7) to mesh with each other and rotate, thereby driving the rotating drum (8), the connecting plate (9) and the baffle (10) to rotate synchronously. The two gears (7) mesh with each other to ensure that the two rotating drums (8) and their connected connecting plate (9) and baffle (10) move synchronously. The baffle (10) can rotate outward or inward: when the baffle (10) rotates outward, its bottom end fits against the inner side wall of the discharge end of the storage tank, forming a blocked discharge port, which is used to catch the skeins falling from the head of the tank and prevent them from falling into the shared discharge conveyor belt and causing material mixing; when the baffle (10) rotates inward and closes, the discharge port is opened, allowing the skein storage tank to discharge normally. This design effectively realizes the anti-mixing function and ensures the smooth conveying of materials in the storage tank.
