Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco manufacturing, and in particular relates to a storage cabinet bottom belt plate type chain cotter pin detection device. Background Art

[0002] In the process of tobacco shreds, many processes require storage cabinets to store materials, which are used to balance the moisture and flavors of tobacco shreds and tobacco leaves during processing, and play a role in buffering the production tasks of the upper and lower processes. The materials in the storage cabinet drive the bottom belt active roller through the motor reducer to drive the chain, and the sprocket on the bottom belt active roller is engaged with the plate chain connected to the bottom belt to complete the material discharge process. The plate chain of the bottom belt of the storage cabinet is grouped into groups of 10-15 links, and each group is connected to each other through the plate chain link. The roller of each link is clamped between the inner and outer chain plates with the pin shaft, and the roller of the chain link is placed on the frame guide rail.

[0003] Since the storage cabinet is often in a state of heavy load, low speed, and frequent start and stop during the unloading process, the chain roller and the pin shaft are worn, resulting in abnormal noise during the unloading process or the link pin shaft rotates synchronously with the roller. Due to the rotation of the link pin shaft, the cotter pin on the pin shaft and the outer chain plate rub against each other, and the cotter pin falls off. If the missing link cotter pin is not found in time, it is easy to cause the link to be disengaged, causing a major shutdown and material interruption accident, affecting the production of the upper and lower processes. Since there are many materials stored in the storage cabinet, once the link is disconnected, it is difficult to repair and replace, which is not conducive to the balance of moisture and flavors in the material in the storage cabinet.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-2 As shown, a cabinet bottom belt plate type chain cotter pin detection device comprises a fixing seat 1, a side plate 2 is arranged on the left side wall of the fixing seat 1, a controller 3 is detachably arranged on the left side wall of the side plate 2, a buzzer 4 is detachably arranged on the top of the left side wall of the side plate 2, a top plate 5 is arranged on the top of the right side wall of the side plate 2, a connecting plate 6 is arranged at the bottom end of the top plate 5, a circular plate 7 is arranged on the bottom wall of the connecting plate 6, a round rod 9 is rotatably connected to the right side wall of the circular plate 7 through a bearing 8, a cylinder 10 is connected to the outer wall of the round rod 9 by interference fit, a lever 11 is arranged at the bottom end of the cylinder 10, and a stopper 12 is arranged on the rear side wall of the lever 11;

[0025] A top seat 13 is provided on the rear side wall of the connecting plate 6, a support plate 14 is provided on the right bottom wall of the top seat 13, a contact sensor 15 is detachably provided on the bottom of the front side wall of the support plate 14, and the controller 3 is electrically connected to the buzzer 4 and the contact sensor 15.

[0026] The outer ring of the bearing 8 is fixedly connected to the outer wall of the circular plate 7 through the bearing seat, and the inner ring of the bearing 8 is connected to the outer wall of the round rod 9 by interference fit. The bearing 8 fixes the round rod 9 and facilitates the rotation of the round rod 9 through the bearing 8.

[0027] The contact sensor 15 is located directly behind the stopper 12 and is in contact with the stopper 12. When the movable chain plate moves to the position of the device, the claw head of the cotter pin is in contact with the lever 11, and the swing lever 11 drives the stopper 12, the cylinder 10 and the round rod 9 to rotate through the bearing 8, causing the stopper 12 to break contact with the contact sensor 15. After the claw head moves away from the bottom of the lever 11, the lever 11 is reset and in contact with the contact sensor 15. When each movable chain plate equipped with a positioning sensor moves to the position of the fixed seat 1, the contact sensor 15 needs to execute two disengagement instructions from the lever 11, and the system determines that the movable chain plate is normal.

[0028] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0029] A specific application of this embodiment is:

[0030] When in use, the device is installed on the outer frame wall of the bottom belt of the storage cabinet through the fixing seat 1 by welding or bolting. The bottom end of the lever 11 is placed above the link pin shaft and disconnected from the link pin shaft at the minimum distance. The two claws of the cotter pin are opened outward after the link pin shaft is inserted and are located on the upper and lower sides of the link pin shaft. There is a movable chain plate every two meters of the plate chain of the bottom belt of the storage cabinet. A positioning sensor is installed on each movable chain plate and connected to the control system.

[0031] When the storage cabinet is working, when the movable chain plate moves to the position of the device, the claw head of the cotter pin contacts the lever 11, and the swing lever 11 drives the block 12, the cylinder 10 and the round rod 9 to rotate through the bearing 8, so that the block 12 breaks the contact with the contact sensor 15. After the claw head moves away from the bottom of the lever 11, the lever 11 is reset and contacts with the contact sensor 15. When each movable chain plate equipped with a positioning sensor moves to the position of the fixed seat 1, the contact sensor 15 needs to execute the disengagement command with the lever 11 twice. The system determines that the movable chain plate is normal. When it is executed once or a disengagement command occurs, the system determines that there is a fault and sounds an alarm through the buzzer 4 to warn the staff to inspect the movable chain plate.

[0032] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the protection scope of the present invention.
