Description

Technical Field

[0001] The utility model relates to the technical field of precision steel ball production, in particular to a precision steel ball anti-stacking mechanism. Background Art

[0002] Steel balls are important basic components, especially precision industrial steel balls play a huge role in the development of the national economy. In the process of steel ball processing, the processing technology of steel balls generally includes a series of processes such as grinding, strengthening, cleaning, oil immersion for rust prevention, collection, counting, weighing, bagging, boxing, labeling, and shipping. During the steel ball processing, a storage and buffer area for steel balls is set between the previous process and the next process. Steel balls are prone to stacking or even jamming, which makes the steel balls unable to smoothly enter the next process, affects the normal operation of the entire production process, and results in low production efficiency of steel balls.

[0003] Based on this, the applicant proposes a precision steel ball anti-stacking mechanism. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that existing precision steel balls are prone to stacking during the production process, the steel balls cannot smoothly enter the next process, and the production efficiency of steel balls is low. The utility model provides a precision steel ball anti-stacking mechanism with reasonable structural design, which can flatten precision steel balls, avoid stacking of precision steel balls during transportation, enable precision steel balls to smoothly enter the next process, and improve the production efficiency of precision steel balls.

[0005] The technical solution adopted by the utility model to solve the technical problems is as follows:

[0006] A precision steel ball anti-stacking mechanism, including a box body, a transmission plate, and a bulletproof structure. A storage bin is provided on the inner wall of the box body. A fixing ring is fixed on the side wall of the box body. A feeding structure is arranged inside the box body. A positioning plate is provided on the top of the outer wall of the box body, and a driving structure is arranged on the positioning plate. The feeding structure includes a first motor and a feeding roller. The first motor is arranged on the outer wall of the box body. The outer wall of the feeding roller is provided with feeding grooves. Connecting shafts are arranged at both ends of the feeding roller. One connecting shaft passes through the fixing ring, and the other connecting shaft is connected to the output shaft of the first motor. The transmission plate is arranged on the outer wall of the box body below the positioning plate, and a rolling groove is arranged on the transmission plate. The bulletproof structure is connected to the driving structure. Pour the precision steel balls into the storage bin. The first motor drives the feeding roller to rotate. The precision steel balls in the storage bin roll onto the feeding grooves on the feeding roller. The feeding roller drives the precision steel balls in the feeding grooves to move upward. After the precision steel balls in the feeding grooves move to the uppermost position, they move downward with the feeding roller. The precision steel balls fall from the feeding grooves under the action of gravity. The precision steel balls fall onto the transmission plate and are transmitted on the transmission plate. The feeding roller drives the precision steel balls in the feeding grooves to rotate and move, so that the precision steel balls fall onto the transmission plate in batches, avoiding stacking of the precision steel balls. The bulletproof structure can prevent the precision steel balls falling onto the transmission plate from bouncing, enabling the precision steel balls to be stably transmitted on the transmission plate, avoiding stacking of the precision steel balls during transmission, and improving the transmission efficiency of the precision steel balls.

[0007] Preferably, the bottom of the storage bin inside the box body is set as an inclined structure, and the lower end of the bottom of the storage bin is in contact with the outer wall of the feeding roller. The precision steel balls poured into the storage bin roll towards the feeding roller, and the precision steel balls enter the feeding grooves and move upward with the rotating feeding roller. The inclined bottom of the storage bin enables the precision steel balls to fully roll towards the feeding roller, avoiding residue of the precision steel balls in the storage bin and improving the feeding efficiency of the precision steel balls.

[0008] Preferably, a blowing structure is arranged inside the feeding roller. The feeding roller is set as a hollow structure, and ventilation grooves penetrating the feeding roller are arranged in the feeding grooves. The connecting shaft inside the fixing ring is set as a hollow structure, and the hollow connecting shaft is communicated with the hollow feeding roller. The precision steel balls fall from the feeding grooves under the action of gravity. The precision steel balls fall onto the transmission plate and are transmitted on the transmission plate. The blowing structure sprays air flow from the ventilation grooves, spraying the precision steel balls in the feeding grooves and improving the discharging efficiency of the precision steel balls in the feeding grooves.

[0009] Preferably, the air injection structure includes an air inlet pipe and an air injection pipe. One end of the air inlet pipe is connected to the air supply device, and the other end enters the feeding roller through a hollow connecting shaft. The air injection pipe is placed inside the feeding roller and is connected to the air inlet pipe. The air supply device blows air into the air inlet pipe, and the air flows out from the air injection pipe. The ejected air flows out from the feeding chute, ejecting the precision steel balls in the feeding chute, preventing the precision steel balls from remaining in the feeding chute. The air injection pipe is horizontally arranged so that the air ejected from the air injection pipe can fully blow the precision steel balls in the feeding chute, causing the precision steel balls in the feeding chute to fully fall.

[0010] Preferably, the cross-section of the rolling groove on the transfer plate is set as a wavy structure. Under the action of gravity, the precision steel balls fall from the feeding chute and land on the transfer plate. The surface of the wavy rolling groove causes the precision steel balls to roll into the rolling groove and move forward in the rolling groove, enabling the precision steel balls to be stably transmitted in the rolling groove, preventing multiple steel balls from stacking during the transmission process, improving the transmission efficiency of the precision steel balls, and thus being able to improve the processing efficiency of the precision steel balls.

[0011] Preferably, the driving structure includes a hydraulic cylinder. The hydraulic cylinder is arranged on the positioning plate. A piston rod is provided on the hydraulic cylinder, and the piston rod is connected to the anti-bouncing structure. The hydraulic cylinder and the piston rod push the anti-bouncing structure downward, preventing it from bouncing up when it lands on the transfer plate, and improving the stability during the transmission process of the precision steel balls.

[0012] Preferably, the anti-bouncing structure includes a connecting plate, a second motor, a rotating roller, and a transmission belt. The connecting plate is connected to the piston rod. A fixing plate is provided on the connecting plate, and a bearing is provided on the fixing plate. The second motor is arranged on the fixing plate. Both ends of the rotating roller are provided with rotating shafts. The rotating shafts are inserted into the bearings, and one of the rotating shafts is connected to the output shaft of the second motor. The transmission belt is arranged between the rotating rollers. The second motor drives the rotating shafts to rotate, and the rotating shafts drive the rotating rollers and the transmission belt between the rotating rollers to rotate. The transmission belt contacts the top of the precision steel balls in the rolling groove, causing the precision steel balls to move forward in the rolling groove under the push of the transmission belt. On the other hand, the transmission belt flattens the precision steel balls in the rolling groove, preventing the precision steel balls from stacking during the movement process, and improving the stability of the precision steel balls during the transmission process.

[0013] Preferably, the surface of the transmission belt is provided with an anti-slip pad, which prevents the phenomenon of slipping between the transmission belt and the precision steel balls, enabling the transmission belt to push the precision steel balls to move forward in the rolling groove and improving the transmission efficiency of the precision steel balls.

[0014] Beneficial effects:

[0015] 1. Pour precision steel balls into the feed bin. Motor 1 drives the feeding roller to rotate. The precision steel balls in the feed bin roll into the feeding grooves on the feeding roller. The feeding roller drives the precision steel balls in the feeding grooves to move upward. After the precision steel balls in the feeding grooves move to the uppermost position, they move downward with the feeding roller. The precision steel balls fall from the feeding grooves under the action of gravity. The precision steel balls fall onto the transfer plate and are transferred on the transfer plate. The bulletproof structure can prevent the precision steel balls that fall onto the transfer plate from bouncing up, enabling the precision steel balls to be smoothly transferred on the transfer plate, avoiding stacking of the precision steel balls during the transfer process, and improving the transfer efficiency of the precision steel balls;

[0016] 2. Set the bottom of the feed bin in the box to an inclined structure, and make the lower end of the bottom of the feed bin contact the outer wall of the feeding roller. The precision steel balls poured into the feed bin roll towards the feeding roller. The precision steel balls enter the feeding grooves and move upward with the rotating feeding roller. The inclined bottom of the feed bin enables the precision steel balls to fully roll towards the feeding roller, avoiding residue of the precision steel balls in the feed bin and improving the feeding efficiency of the precision steel balls;

[0017] 3. Connect one end of the air inlet pipe to the air supply device, and the other end enters the feeding roller through the hollow connecting shaft. Place the air spraying pipe in the feeding roller and connect the air spraying pipe to the air inlet pipe. The air supply device blows air into the air inlet pipe, and the air flows out from the air spraying pipe. The air flow that sprays out sprays out from the feeding grooves, spraying out the precision steel balls in the feeding grooves, avoiding residue of the precision steel balls in the feeding grooves. Set the air spraying pipe horizontally so that the air flow sprayed out by the air spraying pipe can fully blow the precision steel balls in the feeding grooves, enabling the precision steel balls in the feeding grooves to fully fall.
