Description

Technical Field

[0001] This application relates to the field of mechanical transmission equipment maintenance technology, specifically a chain deformation adaptive correction device. Background Technology

[0002] In modern tobacco processing, the storage tank on the tobacco processing line is a key piece of equipment, playing a crucial role in balancing process connections and improving the uniformity of tobacco leaf / shredded tobacco liquor absorption. These storage tanks operate in a high-humidity environment for extended periods and must withstand continuous heavy-load, high-frequency operation; therefore, their chain drive system directly affects the stability of the entire production line. Frictional losses between the rollers and tracks are particularly significant under humid and hot conditions, easily leading to roller shaft corrosion and jamming, causing a chain reaction of problems during equipment operation, such as chain dragging and localized chain link buckling.

[0003] In hot and humid conditions, corrosion of the roller shaft can cause chain dragging, leading to upward arching deformation of some chain links. This arching disrupts the meshing trajectory between the chain and the drive gears, directly causing transmission system jamming or even machine shutdown and material interruption, forcing manual intervention for emergency handling. Current technology lacks the ability to correct chain arching online in real time and a precise anomaly prediction mechanism. This not only leads to a surge in tobacco breakage and a sharp increase in the risk of high-temperature operations for maintenance personnel, but also results in continuous capacity and energy losses due to frequent machine shutdowns for chain replacements.

[0004] Therefore, this application proposes a chain deformation adaptive correction device that can adaptively repair chain arching and provide early warning of abnormalities. Utility Model Content

[0005] The main purpose of this application is to provide a chain deformation adaptive correction device, which aims to solve the technical problem of local chain arching caused by high humidity corrosion in tobacco production storage equipment.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A chain deformation adaptive correction device includes: a housing,

[0008] The bottom of the right side wall of the housing is provided with a fixed seat. The top and bottom inner walls of the housing are respectively rotatably connected to lead screws via bearings. The top wall of the lead screw extends out of the housing and is provided with a handle. A connecting block is threadedly connected to the outer wall of the lead screw. A connecting plate is provided on the right side wall of the connecting block. The right end wall of the connecting plate extends out of the housing and is provided with a repair mechanism for pressing the chain arching.

[0009] As a further improvement of this application, the repair mechanism includes a mounting base, a spring on the bottom wall of the mounting base, a spring seat on the bottom wall of the spring, a connecting rod on the top wall of the spring seat and inside the spring, the top wall of the connecting rod extending out of the mounting base, a top plate on the bottom wall of the spring seat, a side plate on the left side of the bottom wall of the top plate, a pressure wheel rotatably connected to the right side wall of the side plate, and a distance sensor on the left side of the top wall of the top plate.

[0011] As a further improvement of this application, the outer ring of the bearing is fixedly connected to the inner wall of the housing through the bearing seat, and the inner ring of the bearing is interference-fitted with the outer wall of the lead screw.

[0012] As a further improvement of this application, the right side wall of the housing is provided with a long hole communicating with the inner cavity, and the outer wall of the connecting plate is placed in the long hole.

[0013] The technical solution provided in this application may include the following beneficial effects:

[0014] During use, this application uses an elastic clamping mechanism to dynamically and adaptively apply pressure to the arched chain, restoring the flatness of the chain links in real time and ensuring transmission continuity. Combined with the precise detection and early warning of deformation exceeding limits by a distance sensor, it realizes the transformation from passive maintenance to proactive intervention in operation and maintenance mode. Ultimately, it significantly reduces unplanned downtime and tobacco breakage loss, extends the service life of the chain, and avoids manual high-temperature and high-risk maintenance scenarios, achieving a double leap in production efficiency and safety.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1-2 As shown, a repair device for the chain arching problem in tobacco production equipment includes a housing 1. A fixed seat 2 is located at the bottom of the right side wall of the housing 1. A lead screw 5 is rotatably connected to the top and bottom inner walls of the housing 1 via bearings 4. The top wall of the lead screw 5 extends out of the housing 1 and has a handle 6. A connecting block 7 is threaded onto the outer wall of the lead screw 5. A connecting plate 8 is located on the right side wall of the connecting block 7. The right end wall of the connecting plate 8 extends out of the housing 1 and has a repair mechanism for pressing down the chain arching. Through the dynamic adaptive pressure applied to the arched chain by the elastic clamping mechanism, the flatness of the chain links is restored in real time, ensuring transmission continuity. Combined with the precise detection and early warning of deformation exceeding limits by the distance sensor 15, a shift from passive maintenance to proactive intervention in the operation and maintenance mode is achieved. Ultimately, this significantly reduces unplanned downtime and tobacco breakage losses, extends the service life of the chain, and avoids high-temperature and high-risk manual maintenance scenarios, achieving a dual leap in production efficiency and safety.

[0022] Furthermore, the repair mechanism includes a mounting base, a spring 9 on the bottom wall of the mounting base, a spring seat on the bottom wall of the spring 9, a connecting rod 11 on the top wall of the spring seat and inside the spring 9, the top wall of the connecting rod 11 extending out of the mounting base, a top plate 12 on the bottom wall of the spring seat, a side plate 13 on the left side of the bottom wall of the top plate 12, a pressure wheel 14 rotatably connected to the right side wall of the side plate 13, and a distance sensor 15 on the left side of the top wall of the top plate 12.

[0023] Furthermore, the outer wall of the connecting rod 11 is movably inserted into the mounting base.

[0024] Furthermore, the outer ring of the bearing 4 is fixedly connected to the inner wall of the housing 1 through the bearing 4 seat, and the inner ring of the bearing 4 is interference-fitted with the outer wall of the lead screw 5.

[0025] Furthermore, a long hole 3 communicating with the inner cavity is provided through the right side wall of the housing 1, and the outer wall of the connecting plate 8 is placed inside the long hole 3.

[0026] The detailed connection methods are well-known technologies in the field. All components in this solution are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0027] One specific application of this embodiment is:

[0028] When using this device, it is essential to ensure the accuracy and stability of the installation position. We use two reliable installation methods, welding or bolting, to securely install the device on the outer frame wall of the chain side of the tobacco production cabinet equipment via the fixing base 2. During installation, special attention should be paid to adjusting the position of the device so that the pressure wheel 14 can be precisely positioned above the chain to prepare for subsequent operations.

[0029] After the device is installed, the user begins to operate it. The user holds the handle 6 and rotates it in a specific direction. The rotational force of the handle 6 is transmitted to the lead screw 5. Since the lead screw 5 is installed through the bearing 4, the bearing 4 can provide stable support and flexible rotation conditions for the lead screw 5, so that the lead screw 5 can smoothly rotate around its own axis under the drive of the handle 6.

[0030] As the lead screw 5 rotates, the rotation of the lead screw 5 is converted into the linear motion of the connecting block 7. The connecting block 7 then drives a series of connected structures to move downward synchronously. These structures include the connecting plate 8, spring 9, spring seat 10, connecting rod 11, top plate 12, side plate 13, pressure wheel 14, and distance sensor 15, etc.

[0031] As this series of structures moves downward, the pressure wheel 14 gradually approaches the chain until it contacts and presses against the chain surface. At this point, the handle 6 is rotated, the lead screw 5 continues to rotate, and the connecting block 7 moves further downward. This causes the spring 9 to be compressed. The spring 9 has good elasticity and generates a downward thrust during compression. This thrust is transmitted to the pressure wheel 14 through the spring seat 10, connecting rod 11, and other structures, thereby adjusting the pressure of the pressure wheel 14 on the chain. In this way, the user can flexibly adjust the pressure of the pressure wheel 14 on the chain according to the actual running condition and deformation of the chain to achieve the best flattening effect.

[0032] When the chain is driven by the production equipment, the pressure wheel 14 will flatten any arched parts on the chain in real time. Under normal circumstances, the pressure wheel 14 can effectively flatten the slightly arched chain links under the set pressure, so that the chain can maintain a smooth transmission state.

[0033] However, when the chain arches too much, exceeding the flattening range that the pressure wheel 14 can currently compress, the arched chain will generate an upward reaction force on the pressure wheel 14. This reaction force pushes the pressure wheel 14 to move upward, and at the same time drives the connected side plate 13, top plate 12, distance sensor 15 and spring seat 10 and other structures to move upward together.

[0034] During this process, the distance sensor 15 plays a key monitoring role. The distance sensor 15 monitors the change in distance between itself and the connecting plate 8 in real time. When the pressure wheel 14 and related structures move upward due to the arching of the chain, the distance between the distance sensor 15 and the connecting plate 8 will gradually shorten. Once the distance shortens to a preset threshold, the distance sensor 15 will quickly send this information to the control system connected to it.

[0035] After receiving the signal from the distance sensor 15, the control system will immediately trigger the alarm device. The alarm can take the form of sound, light, or other means to attract the attention of the staff and remind them to manually repair the chain. In this way, serious problems with the chain can be detected in time, avoiding equipment failure and production interruption caused by chain abnormalities, and ensuring the smooth progress of tobacco production.

[0036] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
