Description

Technical Field

[0001] The invention belongs to the field of mechanical technology, and in particular relates to a conveyor sprocket device. Background Art

[0002] In the copper electrolysis seed plate stripping unit currently used in copper electrolysis, the seed plate needs to be accurately moved between different processes to achieve automatic stripping of the starting electrode. This process relies on the conveyor, and the stable operation of the conveyor is inseparable from a reliable sprocket device. In the existing conveyor sprocket device, there are many problems that need to be solved: Inconvenient chain tension adjustment: Some sprocket devices lack an effective chain tension adjustment structure. After long-term operation, the chain becomes loose due to wear and other reasons, affecting the power transmission efficiency, resulting in unstable seed plate transportation, and even jamming and falling plates, reducing production efficiency and product quality.

[0003] Poor structural stability: The bracket structure design of some sprocket devices is unreasonable. When subjected to the vibration and impact force generated by the rotation of the sprocket for a long time, it is easy to deform, affecting the installation accuracy of the sprocket shaft and sprocket, thereby shortening the service life of the equipment and increasing maintenance costs.

[0004] The connection between the sprocket and the sprocket shaft is unreliable: The traditional connection method between the sprocket and the sprocket shaft may not guarantee a stable connection under high-load operation. The sprocket is prone to loosening, resulting in a decrease in the matching accuracy between the chain and the sprocket, affecting the normal operation of the conveyor and failing to meet the requirements of the seed plate peeling unit for high precision and high reliability of the conveyor.

[0005] In order to solve the above problems, a new type of conveyor sprocket device was designed to improve the conveyor performance and meet the production needs of the copper electrolytic seed plate stripping unit. Summary of the invention

[0006] The purpose of the present invention is to provide a conveyor sprocket device to solve the problem of poor performance of existing conveyor sprockets.

[0007] The technical solution of the present invention is: a conveyor sprocket device, including a bracket, the bracket including a base plate, two L-shaped support plates are symmetrically and parallelly arranged on the upper surface of the base plate, a long groove with an open end is provided on one side of the upper part of the support plate, and long small grooves are symmetrically provided on the upper and lower sides of the long groove, a seat bearing is provided on the open long groove, a sprocket shaft is provided between the two seat bearings, a sprocket is provided on the sprocket shaft, a tensioning plate is provided on the rear end surface of the support plate through two tensioning screws, a connecting plate is provided on the outer end of the seat bearing, the connecting plate includes a bearing connecting plate and a fixing plate, the outer portion of the lower end surface of the bearing connecting plate is circular, the outer portion of the upper end surface of the bearing connecting plate is square, a fixing plate is provided at a circular plate of the bearing connecting plate away from the center, the fixing plate is arranged parallel to the square side of the bearing connecting plate, and one end of the tensioning screw passes through the fixing plate.

[0008] As a further improvement of the present invention, a rib plate is provided between the outer side of the support plate and the bottom plate.

[0009] As a further improvement of the present invention, the sprocket shaft and the sprocket are fitted with a flat key, and a set screw is provided on the sprocket.

[0010] The beneficial effects of the present invention are as follows: The present invention provides a simple and flexible conveyor sprocket device. The reduction motor drive in the present invention drives the sprocket on the sprocket shaft to rotate, synchronously drives the chain installed between the conveyor drive device and the sprocket device to operate, and drives the seed plate suspended below the chain to move. The tightness of the chain is adjusted by moving the position of the sprocket back and forth on the bracket. The device has a simple, flexible structure, is convenient for installation and maintenance, and meets the performance requirements of the conveyor.

[0011] The present invention also has the following characteristics: 1. Flexible chain tension adjustment: In the present invention, a tension screw and a tension plate are provided on the rear end face of the support plate, and the tension screw passes through the fixing plate on the connecting plate. By simply adjusting the position of the tension screw, the sprocket can be driven to move back and forth in the long groove of the bracket, thereby easily achieving precise adjustment of the tightness of the chain installed on the sprocket. This design enables the chain to always be in an appropriate tension state, ensuring the stability of power transmission, effectively avoiding the seed plate transportation failure caused by chain slack, and improving production efficiency and product quality.

[0012] 2. Stable and reliable structure: A rib plate is added between the outer side of the support plate and the bottom plate, greatly enhancing the structural strength and stability of the bracket. The rib plate can effectively disperse the vibration and impact force generated during the rotation of the sprocket, reduce the possibility of bracket deformation, ensure that the sprocket shaft and the sprocket always maintain an accurate installation position, extend the service life of the equipment, and reduce the maintenance frequency and cost.

[0013] 3. Firm connection between the sprocket and the sprocket shaft: The sprocket shaft and the sprocket are fitted with a flat key, and a set screw is provided on the sprocket. This double fixation method ensures the tight connection between the sprocket and the sprocket shaft under high-load operation, prevents the sprocket from loosening, ensures the good fitting accuracy between the chain and the sprocket, enables the conveyor to operate stably and efficiently, and meets the strict requirements of the copper electrolysis seed plate stripping unit for the high precision and high reliability of the conveyor.

[0014] 4. Convenient for installation and maintenance: The overall device structure is designed simply and reasonably, and the connection method between each component is clear. For example, the bracket is connected to the pedestal bearing, the connecting plate, the tension plate, etc. through bolts, which is convenient for operation during installation and disassembly, facilitating the installation and commissioning and later maintenance of the equipment by the staff, reducing the downtime, and improving the utilization rate of the equipment.
