Description

Technical Field

[0001] The utility model relates to production equipment, in particular to product conveying equipment. Background Art

[0002] The elevator includes a hoisting shaft, a lifting frame arranged in the hoisting shaft, and a conveyor belt installed on the lifting frame. A lifting device is provided at the top of the hoisting shaft, and the lifting device is connected to the lifting frame. The elevator is located between the first product conveyor line and the second product conveyor line, and the height of the first product conveyor line is lower than that of the second product conveyor line. The first product conveyor line transports the product to the conveyor belt on the lifting frame. The lifting device lifts the lifting frame, and the lifting frame and the conveyor belt thereon rise along the hoisting shaft, and the conveyor belt is flush with the second product conveyor line. The conveyor belt transmission transfers the product to the second product conveyor line. In this way, the elevator can realize the transfer of products from a low-level conveyor line to a high-level conveyor line, or from a high-level conveyor line to a low-level conveyor line. However, the conveyor belt of the elevator can generally only realize transmission in the same direction. Utility Model Content

[0003] The technical problem solved by the utility model is that the conveyor belt of the elevator can only realize transmission in the same direction and cannot change the direction of the conveyed products.

[0004] In order to solve the above technical solutions, the present invention provides the following technical solutions: a hoist capable of changing direction, comprising a hoisting shaft, a hoisting device arranged at the top of the hoisting shaft, a lifting frame arranged in the hoisting shaft and connected to the lifting device, and a conveyor belt installed on the lifting frame. The lifting frame is frame-shaped, and a cam divider connected to a motor is provided at the bottom of the lifting frame. The conveyor belt frame is installed on the cam divider. Guard plates are provided on the left and right sides of the conveyor belt frame, and damping rollers are provided at the front and rear ends of the conveyor belt frame. The damping rollers are at the same height as the conveyor belt.

[0005] The elevator is located between the first and second product conveyor lines, with the first product conveyor line at a lower height than the second. The output of the first product conveyor line is in the same direction as the input of the second product conveyor line. The first product conveyor line delivers products to the conveyor belt on the elevator frame. A lifting device raises the elevator frame, and the elevator frame and the conveyor belt on it ascend along the hoist shaft, leveling the conveyor belt with the second product conveyor line. The conveyor belt then drives the products to the second product conveyor line. In this way, the elevator can transfer products from the lower conveyor line to the higher conveyor line in the same direction.

[0006] The elevator is located between the first and second product conveyor lines, with the first product conveyor line at a lower height than the second. The conveying direction of the first product conveyor line's output is perpendicular to the conveying direction of the second product conveyor line's input. The first product conveyor line transports products to the conveyor belt on the elevator frame. The cam divider drives the conveyor belt frame to rotate 90 degrees, and the conveyor belt rotates 90 degrees accordingly. The lifting device raises the elevator frame, and the elevator frame and the conveyor belt on it rise along the hoist shaft until the conveyor belt is flush with the second product conveyor line. The conveyor belt drives the product to the second product conveyor line. In this way, the elevator can achieve a 90-degree change in conveying direction from the lower conveyor line to the higher conveyor line.

[0007] The elevator of the utility model can change the conveying direction of products, thereby expanding the application range of the elevator.

[0008] As the first product conveyor line feeds products onto the conveyor belt, a damping roller at the front end of the conveyor frame contacts the bottom of the product, slowing the product's conveyance and preventing it from sliding off the conveyor belt due to inertia. A damping roller at the rear end of the conveyor frame also prevents the product from sliding off the conveyor belt. Because the conveyor belt rotates 90 degrees, the guard plate and damping roller effectively confine the product to the conveyor belt, preventing it from sliding off during rotation.

[0009] The conveyor frame includes a conveyor frame base plate connected to the cam divider, a pair of support beams fixed to the conveyor frame base plate, a conveyor edge structure fixed to the pair of support beams, a conveyor roller of the conveyor belt pivotally connected to the conveyor edge structure, a bracket for the damping roller fixed to the conveyor frame base plate, a conveyor drive motor fixedly connected to the conveyor edge structure, and a conveyor drive motor shaft driving the conveyor roller of the conveyor belt to rotate through a transmission mechanism. The transmission mechanism can be a synchronous belt or a transmission chain.

[0010] The lifting device includes a first driving sprocket and a second driving sprocket mounted on the same drive shaft, a first transmission chain engaged with the first driving sprocket, a second transmission chain engaged with the second driving sprocket, and a counterweight connecting the tail ends of the first and second transmission chains. The first end of the first transmission chain is connected to the front end of the lifting frame via a transfer sprocket, and the first end of the second transmission chain is connected to the rear end of the lifting frame. The drive shaft is driven by a power unit 28, which can be composed of a motor and a pair of helical gears. The motor drives the pair of helical gears, which in turn drive the drive shaft to rotate. Driven synchronously by the first and second transmission chains, the lifting frame rises while the counterweight descends, and the lifting frame descends while the counterweight rises.

[0011] A hoist frame guide rail is installed in the hoist shaft, and a hoist frame slider is installed on the hoist frame to cooperate with the hoist frame guide rail. A limiter is provided at the bottom of the hoist frame guide rail, and a pressure structure is provided at the bottom of the hoist frame slider to abut against the limiter. When the hoist frame descends to its lowest position, the pressure structure abuts against the limiter, preventing the hoist frame from colliding with parts at the bottom of the hoist shaft and potentially damaging the hoist.

[0012] A counterweight guide rail is provided in the lifting shaft, and a counterweight sliding block which cooperates with the counterweight guide rail is provided on the counterweight.

[0013] The lift frame is equipped with a sensor contact, and the lift frame guide rails are equipped with contact sensors. The contact sensors include a lower sensor and an upper sensor. When the sensor contact contacts the lower sensor, the lift mechanism stops and the lift frame remains in place. At this point, the conveyor belt is aligned with the first product conveyor line. When the sensor contact contacts the upper sensor, the lift mechanism stops and the lift frame remains in place. At this point, the conveyor belt is aligned with the second product conveyor line.
