[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figure 1-16 shown, a drum for a steel ball strengthening machine, the drum 1 is provided with a feed inlet, and a cover 2 is provided at one end of the drum 1 that cooperates with the feed inlet. A plurality of strengthening plates are rotatably installed on the inner side wall of the drum 1, all the strengthening plates are spaced apart, and any one of the strengthening plates is detachably connected to the drum 1.

[0036] By providing a rotatable reinforcement plate, the present invention improves the applicable range of the drum. For steel balls of different specifications, the drum can strengthen them. The reinforcement plate is set in a detachable form, and the reinforcement plate and the interior of the drum can be cleaned separately, which is convenient for independent cleaning of the drum, improves the cleaning efficiency, reduces the cleaning difficulty, and can clean more thoroughly.

[0037] In the present invention, a drum shaft is provided at the rear end of the drum. The drum shaft can be connected to a driving component to make it rotate. The reinforcement plate provided on the inner side wall of the drum is used to lift the steel balls, so that the steel balls fall after reaching the highest point and collide with other steel balls, thereby increasing the stress of the steel balls to achieve the effect of strengthening the steel balls.

[0038] The reinforcement plate includes a socket part 3 and a reinforcement part 4. The socket part 3 is fixedly connected to the reinforcement part 4, and the socket part 3 is radially provided with splines; an installation through groove 11 is provided on the inner side wall of the drum 1 to cooperate with the socket part 3, and the reinforcement part 4 is arranged towards the center of the drum 1.

[0039] The reinforcement part 4 includes a connecting part 41 and a reinforcement part 42 which are integrally connected; the socket part 3 is a semi-circular ring, and the socket part 3 is sleeved outside the connecting part 41.

[0040] In the present invention, the reinforcement plate is formed by assembling the socket part 3 and the reinforcement part 4. The reinforcement part 4 includes two parts, a connecting part 41 and a reinforcement part 42, which are integrally connected. The connecting part 41 is cylindrical, and the reinforcement part 42 is a cuboid. An arc surface is provided at one end of the reinforcement part 42 away from the connecting part 41. The sharp corner is easier to be broken compared to the arc surface. The long side of the reinforcement part 42 is equal to the length of the inner wall of the drum 1; the socket part 3 is sleeved outside the connecting part 41, and the splines of the socket part 3 cooperate with the installation through groove 11. By providing the socket part 3, the reinforcement part can be detachably connected to the drum 1; by providing splines on the socket part 3, the reinforcement plate can be fixed on the drum firmly when the drum rotates and will not rotate relative to the drum; and when the angle between the reinforcement plate and the drum needs to be changed according to the steel ball specifications, the worker can pull out the reinforcement plate and then rotate it by a certain angle and assemble it into the installation through groove.

[0041] The socket part 3 includes a first vulcanized rubber layer 31 and a second vulcanized rubber layer 32, and a metal layer 33 is provided between the first vulcanized rubber layer 31 and the second vulcanized rubber layer 32.

[0042] In the present invention, as Figure 5As shown, the socket part 3 includes three layers of structures. The first vulcanized rubber layer 31 is arranged on the outermost layer, the second vulcanized rubber layer 32 is arranged on the innermost layer, and the side of the metal layer 33 close to the first vulcanized rubber layer 31 is also provided with splines, which are matched with the splines of the first vulcanized rubber layer. For example, if the splines of the first vulcanized rubber layer include 20 teeth, then the splines of the metal layer also include 20 teeth, and the teeth between the two splines are arranged in correspondence; by setting the metal layer matched with the first vulcanized rubber layer in the present invention, it is possible to prevent the phenomenon that the socket part 3 is deformed due to the roller rotating too fast or the steel balls falling and hitting the strengthening plate, resulting in the relative rotation of the strengthening plate and the roller, and improving the fixing reliability of the strengthening plate.

[0043] A plurality of telescopic support column assemblies 5 are embedded in the cylinder wall of the roller 1, and all the telescopic support column assemblies 5 are connected to a driving assembly 6, and any one of the telescopic support column assemblies 5 is arranged in cooperation with any one of the strengthening plates.

[0044] Any one of the telescopic support column assemblies 5 includes at least one telescopic sleeve rod 51. One end of all the telescopic sleeve rods 51 is provided with a buffer member 52, and the other ends of all the telescopic sleeve rods 51 are matched with the driving assembly 6.

[0045] The telescopic sleeve rod 51 is a threaded telescopic sleeve rod; the driving assembly 6 includes a plurality of driven members 61 and a driving member. Any one of the driven members 61 and the driving member are matched with one end of all the threaded telescopic sleeve rods in the corresponding telescopic support assembly, and a synchronous transmission member 62 is arranged outside the roller 1 in cooperation with all the driven members 61 and the driving member.

[0046] In the present invention, for example, as Figure 16 shown, one strengthening plate corresponds to one telescopic support column assembly 5. One telescopic support column assembly 5 includes two threaded telescopic sleeve rods 51. Each threaded telescopic sleeve rod 51 includes a screw rod, and the screw rod is rotatably installed on the roller between the inner side wall and the outer side wall. One end of the screw rod is fixedly connected to a first bevel gear, and a matching screw sleeve is sleeved on the other end of the screw rod. The screw sleeve passes through the inner wall of the roller, and the top of the screw sleeve is fixedly connected to the buffer member 52. The buffer member 52 is of a hemispherical structure, and the buffer member 52 can be made of rubber or other materials; combined with Figure 15 shown, 16 first bevel gears are all matched with the driving assembly 6 to drive 16 screw rods to rotate so that the corresponding screw sleeves can move along the screw rods.

[0047] Correspondingly, as Figure 16As shown, each follower 61 includes two second bevel gears. A spur gear is axially connected between the two bevel gears. The follower is rotatably installed within the barrel wall of the drum 1. The diameter of the spur gear is larger than that of the second bevel gear, and the spur gear penetrates through the outer wall of the drum 1. One of the eight followers is connected to a driving member (not shown in the figure), that is, connected to the motor shaft. The spur gears on all followers are cooperatively provided with a gear timing belt. The motor can be arranged on the front side of the drum 1, or the motor can be electrically connected to a motor driver, and the motor driver is wired or wirelessly connected to a controller, and the controller controls the rotation of the motor. The working principle is as follows: The motor drives the corresponding follower to rotate. Taking the spur gear on this follower as the driving wheel and the spur gears on other followers as the driven wheels, all the driven wheels rotate synchronously under the action of the gear timing belt and the driving wheel, realizing the rotation of all followers. Then, the second bevel gears on the followers can all rotate, driving the first bevel gears to rotate.

[0048] In the present invention, since each reinforcement plate has to bear a part of the steel balls to lift them upward, the steel balls will fall from top to bottom and impact the reinforcement plate. By providing a telescopic strut assembly, the stability of the steel ball reinforcement plate is further improved, preventing the socket parts and the reinforcement parts from cracking under the impact of the steel balls, and enhancing the service life of the reinforcement plate.

[0049] The cover 2 includes a first cover plate 21. A limiting groove 23 is provided at the rear side of the first cover plate 21. A second cover plate 22 is arranged within the limiting groove 23. The second cover plate 22 is rotatably connected to the first cover plate 21. The diameter of the first cover plate 21 is larger than that of the second cover plate 22, and the diameter of the second cover plate 22 is larger than the diameter of the feed port. There are several cover connection plates on the front side of the drum 1 that cooperate with the first cover plate 21 and the second cover plate 22.

[0050] The cover connection plates include several first cover connection plates 71 and several second cover connection plates 72. All the first cover connection plates 71 cooperate with the first cover plate 21, and all the second cover connection plates 72 cooperate with the second cover plate 22. The first cover connection plates 71 and the second cover connection plates 72 are both arranged on the front side of the drum 1 between adjacent two reinforcement plates.

[0051] In the present invention, the height difference between the first cover connection plate 71 and the front end face of the drum 1 is equal to the height of the first cover plate 21, and the height between the second cover connection plate 72 and the front end face of the drum 1 is equal to the height of the second cover plate 22.

[0052] As Figure 6-15As shown, for example, the first cover plate 21 is semi-circular, the thickness of the first cover plate 21 is 3 cm, a semi-circular limiting groove 23 is provided on the side of the first cover plate 21 close to the reinforcing plate, the thickness of the limiting groove 23 is 1.5 cm, the size of the second cover plate is the same as that of the limiting groove, and the limiting groove is used for placing the second cover plate 22; the rear end face of the first cover plate is fixedly connected with a central support member, the central support member is cylindrical, and a central axis is provided rearward on the rear end face of the central support member; the second cover plate is provided with a central axis socket, and correspondingly, an installation groove for installing the central axis socket is provided between the first cover plate 21 and the central axis.

[0053] Since the cover connection plate is used to cooperate with the cover, 4 first cover connection plates are arranged on the left semi-circle, 4 second cover connection plates are arranged on the right semi-circle, the 4 first cover connection plates are arranged adjacent to each other, the 4 second cover connection plates are arranged adjacent to each other, and any cover connection plate is arranged on the front side of the drum between two adjacent reinforcing plates; the height of the first cover connection plate is the same as the thickness of the first cover plate, both are 3 cm, and the height of the second cover connection plate is the same as the thickness of the second cover, both are 1.5 cm.

[0054] When the drum needs to be sealed, first stack the first cover plate and the second cover plate into a semi-circular cover structure, as Figure 11 shown, and the second cover plate is arranged at the rear side of the first cover plate, arrange the semi-circular cover structure between the drum and the first cover connection plate, and then rotate the second cover plate so that the second cover plate is arranged between the drum and the second cover connection plate, as Figure 12 shown.

[0055] Furthermore, referring to Figure 13 , a handle can be provided at the lower edge of the second cover plate, a limiting through groove is provided at the upper edge of the first cover plate to cooperate with the handle, and a sealing part for covering the limiting through groove is provided at the upper edge of the second cover plate; by providing the handle, it is convenient to install the cover plate on the drum and to rotate the second cover plate, so that the cover plate covers the drum.

[0056] At least one first cover connection plate 71 and at least one second cover connection plate 72 are respectively provided with limiting members 721, and the first cover plate and the second cover plate 22 are respectively provided with limiting connection grooves 24 in cooperation with the limiting members 721.

[0057] In the present invention, the limiting member and the limiting connection groove cooperate to prevent the cover from rotating relative to the drum and increase the packaging reliability of the cover.
