Product Potential

 

1. Compared with other similar products, Zhengzhou Welite double roller ball press has obvious advantages such as high ball forming rate, low power consumption, compact structure and easy maintenance and debugging.

 

2. Our company's roller ball press product has three points of high density, high strength and high hardness, and the press roller of this machine adopts 65mn hard material, which has good wear resistance. Effectively improve the service life of the pressure roller.        

 

3. Zhengzhou Weilit does both products and services for every customer. For the installation and commissioning of the roller ball press and production line, the manufacturer’s technicians will personally come to the door to install and guide. Let customers worry and effort.

 

       The main structure of the roller ball machine is composed of transmission system, main frame, reducer, belt conveyor, pre-compression device, roller sleeve ball slot alignment device, hydraulic system and electronic control. When working, the material is added quantitatively and evenly to the pre-compression device of the ball press to maintain a stable material level in the pre-compression device, and then the pre-compression screw in the pre-compression device forcibly presses the material into the middle of the pair of rollers to pre-compress and transport the material To the arc-shaped slots of the two pairs of rollers, the surfaces of the two pairs of rollers are evenly distributed with the same shape of the roller sockets. Through the meshing transmission, the two pairs of rollers are rotated at the same speed and reversely, and the material conveyed to the notches is bitten into the groove. The internal and forced compression, as the pair of rollers continue to rotate, the ball will fall off under the action of its elastic force and gravity, and the motor continuously rotates the pressing roller to make periodic rotation and compression molding, realizing mass production.

 

transfer method

 

       In order to meet the requirements of material forming, the pre-compression screw adopts an electromagnetic speed-regulating motor, and the speed-regulating method is manual. The user can appropriately change the speed of the pre-press according to the ball-forming situation to achieve high ball-forming rate and large production capacity. , The compressed material is sieved through the screening machine, and the qualified pellets are sieved for packaging, and the sieved material can be returned to the bin to mix with the new material and then be compressed.

 

Principle of hydraulic protection device

 

       The hydraulic protection device of the roller ball machine uses a hydraulic pump to drive high-pressure oil into the hydraulic cylinder to cause the piston to produce axial displacement. The front joint of the piston rod rests on the bearing seat to meet the production pressure requirements. When there is too much feed between the two pressure rollers or metal blocks, the piston rod of the hydraulic cylinder is overloaded, the hydraulic pump will stop, the accumulator will buffer the pressure change, the overflow valve will open to return the oil, and the piston rod will shift. The gap between the pressure rollers is enlarged so that the hard objects pass through the pressure roller, and the system pressure returns to normal, which can protect the pressure roller from damage. The pressure can be adjusted according to the requirements of the pressure ball density, and the production is flexible and flexible.

 

 Finished spherical

 

       The roller ball press can produce square, ball and egg, round, goose, pillow and other spherical shapes for users to choose from. The special ball press sphere can be defined by our company according to the needs of users. The finished product sample is shown in the figure below:
