[0033] Reference Figure 3 and Figure 4 The rotating assembly 4 includes a lifting cylinder 41 and a rotating motor 42. The lifting cylinder 41 is fixedly installed in the conveying frame 3 along the height direction of the conveying frame 3. A lifting plate 43 is fixedly installed at the end of the piston rod of the lifting cylinder 41. The rotating motor 42 is installed on the lifting plate 43 along the height direction of the conveying frame 3. A rotating plate 44 located between two conveying rollers 31 is arranged at the end of the output shaft of the rotating motor 42. When the steel drum cover moves above the rotating plate 44, the lifting cylinder 41 is started, and the lifting plate 43 drives the rotating motor 42 and the rotating plate 44 to move upward. The rotating plate 44 supports the steel drum cover, so that the steel drum cover moves upward and separates from the conveying roller 31, and the rotating motor 42 is started to rotate the steel drum cover. Among them, a plurality of through holes 441 are equidistantly spaced on the rotating plate 44 in the circumferential direction to reduce the weight of the rotating plate 44 while maintaining the stability of the rotation of the rotating plate 44.

[0034] Reference Figure 2A plurality of magnetic elements are arranged at equal intervals in the circumferential direction on the upper surface of the rotating plate 44. The magnetic elements can be magnets for adsorbing the steel drum cover. The steel drum cover is a material that can be adsorbed by the magnetic elements. During the rotation of the rotating plate 44, the steel drum cover is adsorbed on the rotating plate 44 by the magnetic elements, thereby improving the stability of the steel drum cover during rotation.

[0035] Reference Figure 1 , a transfer assembly 21 is arranged on the mounting frame 2, and the transfer assembly 21 includes a transverse track 211, a lifting track 212 and an air suction mechanism 5. The transverse track 211 is installed on the mounting frame 2 along the width direction of the conveying frame 3, a moving seat 213 is installed on the transverse track 211, and the lifting track 212 is fixedly installed on the moving seat 213 along the height direction of the conveying frame 3. A lifting seat 214 is arranged on the lifting track 212, and the air suction mechanism 5 is installed on the lifting seat 214. After the rotation is completed, the lifting seat 214 moves to the top of the steel drum cover, and after the air suction mechanism 5 adsorbs the steel drum cover, the lifting track 212 is started, and the moving seat 213 drives the steel drum cover to move upward, and then the transverse track 211 is started, and the moving seat 213 moves horizontally, and the steel drum cover is moved to the top of the placement table 1, and the steel drum cover is stacked in sequence.

[0036] Reference Figure 1 The suction mechanism 5 includes an air pump 53, a plurality of suction discs 51 and a plurality of suction pipes 52. The plurality of suction pipes 52 are connected to the plurality of suction discs 51 in a one-to-one correspondence. The plurality of suction discs 51 are all installed at the bottom of the lifting seat 214. The air pump 53 is installed on the lifting seat 214 and is connected to all the suction pipes 52. When the moving seat 213 moves to the top of the steel drum cover, the suction disc 51 abuts against the top of the steel drum cover, the air pump 53 is started, and the suction disc 51 absorbs the steel drum cover, thereby facilitating the transportation of the steel drum cover.

[0037] Reference Figure 2 and Figure 4 Two first blocking rods 32 are installed at the output end of the conveying frame 3. The distance between the two first blocking rods 32 is smaller than the width of the steel drum cover. The conveying frame 3 is provided with auxiliary plates 33 on both sides along the width direction of the conveying frame 3. The distance between the two auxiliary plates 33 matches the width of the steel drum cover. The two first blocking rods 32 block the first steel drum cover conveyed by the conveying roller 31, limit the position of the steel drum cover, and facilitate the rotation and transportation of the steel drum cover.

[0038] Reference Figure 2 and Figure 4Two second blocking rods 431 are arranged between the two groups of rotating components 4. The two second blocking rods 431 are installed above the lifting plate 43 near the output end of the conveying frame 3, and the distance between the two second blocking rods 431 is less than the width of the steel drum cover. When the first steel drum cover passes through the second blocking rod 431 and collides with the first blocking rod 32, the lifting cylinder 41 is started, and while the lifting plate 43 rises, the two second blocking rods 431 move upward to block the second steel drum cover.

[0039] Reference Figure 2 and Figure 4 A blocking track 6 is provided near the input end of the conveying frame 3. The blocking track 6 is installed on the conveying frame 3 along the width direction. The height of the blocking track 6 is lower than the height of the conveying roller 31. A bidirectional lead screw 61 is rotatably connected in the blocking track 6. A driving motor is installed on the blocking track 6. The output shaft of the driving motor is coaxially fixedly connected with the bidirectional lead screw 61. Blocking seats 62 are penetrated on both sides of the bidirectional lead screw 61. The two blocking seats 62 are provided with third blocking rods 63. The end height of the third blocking rod 63 is higher than the height of the conveying roller 31. When the second steel drum cover passes through the third blocking rod 63 and collides with the second blocking rod 431, the bidirectional lead screw 61 is rotated to bring the two blocking seats 62 closer to each other, so that the two third blocking rods 63 are closer to each other, and the steel drum cover behind is blocked.

[0040] Among them, the rotating assembly 4 closest to the output end of the conveying frame 3 is the first group of rotating components 4, and the other group of rotating components 4 is the second group of rotating components 4. A first pressure sensor is installed on the first blocking rod 32, and the first pressure sensor is electrically connected to the controller. When the first steel drum cover collides with the first blocking rod 32, the first pressure sensor on the first blocking rod 32 sends a first pressure signal to the controller, and the controller receives the first pressure signal and sends a lifting signal to the lifting cylinder 41 of the first group of rotating components 4. The lifting plate 43 of the first group of rotating components 4 moves upward. While lifting the first steel drum cover, the second blocking rod 431 on the lifting plate 43 moves upward to block the second steel drum cover. A second pressure sensor is installed on the second blocking rod 431, and the second pressure sensor is electrically connected to the controller. When the second steel drum cover collides with the second blocking rod 431, the second pressure sensor on the second blocking rod 431 sends a second pressure signal to the controller, and the controller is electrically connected to the drive motor. After receiving the second pressure signal, the controller sends a lifting signal to the lifting cylinder 41 of the second group of rotating components 4, and at the same time sends a rotation signal to the drive motor, so that the two-way screw 61 rotates to bring the two blocking seats 62 closer to each other, and the two third blocking rods 63 closer to each other, so as to block the steel drum cover behind. At the same time, the rotating plate 44 of the second group of rotating components 4 moves upward to lift the steel drum cover.

[0041] When the rotating motor 42 rotates, according to the number of times the controller receives the first pressure signal, the output shaft of the rotating motor 42 rotates at a different angle each time, the first rotation is 0 degrees, the second rotation is 90 degrees clockwise, the third rotation is 180 degrees clockwise, and the fourth rotation is 90 degrees counterclockwise. Four times form a group, so that the relative angles between adjacent stacked steel drum covers are all 90 degrees, and the two flanges of different heights on the steel drum covers are staggered to prevent the stacked steel drum covers from tipping over.

[0042] Reference Figure 2 The conveying frame 3 is provided with a guide plate 34 located below the lifting plate 43, and a plurality of guide rods 432 are provided at the bottom of the lifting plate 43. The guide plate 34 is provided with guide openings corresponding to the guide rods 432 one by one, and the guide rods 432 pass through the guide openings and are slidably connected to the guide plate 34. During the lifting and lowering movement of the lifting plate 43, the guide rods 432 move in the guide openings, and the guide plate 34 provides a limit guide for the movement of the guide rods 432, thereby improving the stability of the lifting and lowering process of the lifting plate 43.

[0043] Reference Figure 2 A plurality of auxiliary rollers 35 rotatably connected to the conveying frame 3 are arranged between two adjacent conveying rollers 31 of the rotating plate 44, and the plurality of auxiliary rollers 35 are arranged in pairs on both sides of the width direction of the rotating plate 44. The auxiliary rollers 35 support both sides of the bottom of the steel drum cover to improve the stability of the movement of the steel drum cover.

[0044] The implementation principle of the automatic capping device for preventing steel drum covers from tipping over in the embodiment of the present application is as follows: the steel drum cover is placed on the conveying frame 3, and the conveying roller 31 rotates to make the steel drum cover move on the conveying frame 3. When the steel drum cover moves to the top of the rotating plate 44, the lifting cylinder 41 is started, and the lifting plate 43 drives the rotating motor 42 and the rotating plate 44 to move upward. The rotating plate 44 supports the steel drum cover, so that the steel drum cover moves upward and separates from the conveying roller 31. The rotating motor 42 is started to rotate the steel drum cover. After the rotation is completed, the lifting seat 214 moves to the top of the steel drum cover, and the suction mechanism 5 After the steel drum cover is adsorbed, the lifting track 212 is started, and the moving seat 213 drives the steel drum cover to move upward, and then the horizontal track 211 is started to transfer the steel drum cover and stack the steel drum covers in sequence. The rotating motor 42 rotates 0 degrees for the first time according to the steel drum cover, 90 degrees clockwise for the second time, 180 degrees clockwise for the third time, and 90 degrees counterclockwise for the fourth time. Four times form a group, so that the relative angles between adjacent stacked steel drum covers are all 90 degrees, and the two flanges of different heights on the steel drum cover are staggered to prevent the stacked steel drum covers from tipping over.

[0046] Among them, in step S3, the rotating plate 44 has four rotation modes: S31, rotate 0°; S32, rotate 90° clockwise; S33, rotate 180° clockwise; S34, rotate 90° counterclockwise, and the rotating plate 44 repeats these four rotation modes in sequence.

[0047] Specifically, during the specific rotation of the rotating plate 42, according to the number of times the controller receives the first pressure signal, the rotation angle of the output shaft of the motor 42 is different each time, the first rotation is 0 degrees, the second rotation is 90 degrees clockwise, the third rotation is 180 degrees clockwise, and the fourth rotation is 90 degrees counterclockwise, four times as a group, so that the relative angles between adjacent stacked steel drum covers are 90 degrees, and the two flanges of different heights on the steel drum covers are staggered to prevent the stacked steel drum covers from tipping over.
