Description

Technical Field

[0001] The invention relates to the technical field of screening machines, in particular to a cleaning device for rubber balls of screening machines. Background Art

[0002] Traditional vibratory screening equipment uses mechanical vibration to separate powders into particle sizes through a sieve of a certain mesh size. To prevent clogging, the powder flows rapidly across the sieve. The additive manufacturing process places high demands on powder quality. In addition to powder composition, other parameters such as particle size, sphericity, and powder flowability all impact the powder printing process. Therefore, powders that meet additive manufacturing specifications require further sieving of spherical powders before loading into the machine to prevent agglomeration during storage, which could impact the printing process. Consequently, during the screening process, the powder remains on the sieve for extended periods, making it prone to clogging.

[0003] To address these issues, the Russell additive powder screening equipment features a screen design that reduces vibration amplitude. This vibration causes the rubber balls below the screen to impact the screen at a high frequency, preventing screen clogging and accelerating powder screening. This design requires cleaning not only the screen frame and screen, but also the rubber balls during the screening process.

[0004] The existing rubber ball cleaning process requires first using an explosion-proof vacuum cleaner to clean the dust on the rubber ball surface, then cleaning the rubber ball surface with alcohol, and finally using a hair dryer to dry the rubber ball before returning it to the equipment. During the cleaning process, since the diameter of the rubber ball is only 10mm, it is difficult for the explosion-proof vacuum cleaner to clean the rubber ball thoroughly, and occasionally the rubber ball will be sucked into the vacuum cleaner through the suction pipe, such as Figure 1 Cleaning is difficult. If the surface powder is not completely removed, residual powder may adhere to the rubber ball during subsequent cleaning with alcohol. Furthermore, cleaning each rubber ball takes an average of 2-4 minutes. Since many rubber balls are used at once, the entire cleaning process takes approximately 2 hours, resulting in low cleaning efficiency. Prolonged contact with powder attached to the rubber ball during cleaning can be harmful to the human body, so protective masks and protective clothing must be worn throughout the cleaning process. Summary of the Invention

[0005] The purpose of the invention is to provide a cleaning device for rubber balls of screening machines, which solves the problems that the existing rubber balls are not cleaned properly and affect the subsequent process, the rubber balls are small and easily sucked into the vacuum cleaner, and the cleaning efficiency is low.

[0006] The present invention is implemented as follows: a cleaning device for rubber balls of a screening machine includes a vacuum cleaner, a cover body, a connecting plate assembly, and a ball bearing. The cover body is trumpet-shaped and the end with a small diameter is connected to the vacuum cleaner through a vacuum tube. The connecting plate assembly is placed at the end with a large diameter of the cover body. The connecting plate assembly is provided with a through hole for placing the rubber ball. The ball bearing is placed on the inner wall of the through hole and can roll. The contact between the ball bearing and the rubber ball can drive the rubber ball to rotate.

[0007] Multiple rubber balls can be placed in multiple corresponding through holes, and the suction force of the vacuum cleaner can make the balls rotate. The balls can roll in any direction, and the balls are in constant contact and friction with the rubber balls during the rotation process, so that the rubber balls are cleaned in all directions. The cleaned powder is sucked away by the vacuum cleaner and will not be absorbed by the human body, avoiding harm. After the powder cleaning is completed, wipe the surface of the rubber ball with a dust-free cloth dipped in alcohol. Multiple rubber balls can be wiped at one time, and the balls can be wiped in all directions under the action of the vacuum cleaner. The alcohol can evaporate quickly under the action of the vacuum cleaner, thereby improving the cleaning efficiency.

[0008] A further technical solution of the present invention is: the through hole includes a circular hole and a limiting groove opened on the periphery of the circular hole and connected to the circular hole, the ball is placed in the limiting groove, and the rubber ball is placed in the circular hole.

[0009] A further technical solution of the present invention is that the diameter of the connection point between the limiting groove and the circular hole is smaller than the diameter of the ball, and the diameter of the limiting groove is larger than the diameter of the ball.

[0010] The diameter of the connection between the limiting groove and the circular hole is smaller than the diameter of the ball to prevent the ball from falling during movement; the diameter of the limiting groove is larger than the diameter of the ball to ensure that the ball can roll freely in the limiting groove.

[0011] A further technical solution of the present invention is that the limiting grooves are evenly distributed around the periphery of the circular hole.

[0012] Ensure that the rubber ball can bear even force during cleaning.

[0013] A further technical solution of the present invention is that the limiting grooves are symmetrically distributed around the periphery of the circular hole.

[0014] A further technical solution of the present invention is: the connecting plate assembly includes an upper closing plate and a lower closing plate, and both the upper closing plate and the lower closing plate are detachably connected to the cover body.

[0015] The upper and lower closing plates are designed to accommodate balls, as the diameter of the balls is larger than the opening of the limiting grooves.

[0016] A further technical solution of the present invention is that the balls are placed between the upper cladding plate and the lower cladding plate.

[0017] A further technical solution of the present invention is that a positioning hole is further provided on the connecting plate assembly, a positioning block corresponding to the position of the positioning hole is provided on the cover body, and the connecting plate assembly is fixed to the positioning hole by screws passing through the positioning hole.

[0018] The design of the positioning holes and the positioning blocks enables the connection plate assembly to be smoothly installed on the cover body, and the screws are removable, so that the connection assembly can also be disassembled during installation.

[0019] A further technical solution of the present invention is that the cover body and the dust suction pipe are detachably connected.

[0020] Convenient to use the cleaning device.

[0021] A further technical solution of the present invention is: the ball is made of stainless steel and has a diameter of 4 mm.

[0022] The beneficial effects of the present invention are as follows: the present invention greatly reduces the difficulty of cleaning the rubber balls, speeds up the cleaning process, and can clean multiple rubber balls at the same time, saving cleaning time and reducing the impact of powder on the human body during the process;

[0023] In the present invention, multiple rubber balls can be placed in multiple corresponding through holes, and the balls can be rotated by the suction of the vacuum cleaner. The balls can roll in any direction, and the balls are in constant contact and friction with the rubber balls during the rotation process, so that the rubber balls are cleaned in all directions. The cleaned powder is sucked away by the vacuum cleaner and will not be absorbed by the human body, avoiding causing harm. After the powder cleaning is completed, the surface of the rubber balls is wiped with a dust-free cloth dipped in alcohol. Multiple rubber balls can be wiped at one time, and the balls can wipe in all directions under the action of the balls, and the alcohol can evaporate quickly under the action of the vacuum cleaner, thereby improving the cleaning efficiency.
