The locking mechanism 1 works in conjunction with the passive rotating mechanism 202 to control the rotation and stop of the passive rotating mechanism 202. The active rotating mechanism 201 and the passive rotating mechanism 202 are magnetically coupled together. By controlling the working state of the passive rotating mechanism 202 through the locking mechanism 1, square bars are placed on the passive rotating mechanism 202, and continuous aligned conveying of materials is achieved through the mutual attraction of the magnets.

[0028] Furthermore, the locking mechanism 1 includes a drive device 101, a V-groove plate 102, a pressure claw 103, a rotating shaft plate 104, a first rotating shaft 105, and a second rotating shaft 106. When the drive device 101 operates, it acts on the pressure claw 103 through the V-groove plate 102. The pressure claw 103 interacts with the passive rotating mechanism 202, at which point the passive rotating mechanism 202 stops rotating.

[0029] Furthermore, the locking mechanism 1 includes a drive device 101 and a clamping bearing. Two drive devices 101 are symmetrically arranged, and the clamping bearing is rotatably mounted at the end of the drive device 101. The drive device 101 drives the clamping bearing to clamp the passive rotating mechanism 202 from both sides, at which time the passive rotating mechanism 202 stops rotating.

[0030] Furthermore, the active rotation mechanism 201 includes a base 2011, a bearing seat 2012, a first feeding shaft 2013, and a first magnetic block 2014. The passive rotation mechanism 202 includes an outer sleeve 2021, a first bearing 2022, a positioning sleeve 2023, a second feeding shaft 2024, and a second magnetic block 2025. A triangular groove 3 is provided on the outer wall of the positioning sleeve 2023 to cooperate with the pressure claw 103. Square holes 4 are provided on both the first feeding shaft 2013 and the second feeding shaft 2024. The first feeding shaft 2013 and the second feeding shaft 2024 are coaxially arranged. The pressure claw 103 or the clamping bearing can fix the positioning sleeve 2023 through the triangular groove 3, thereby fixing the passive rotation mechanism 202.

[0031] Furthermore, the V-groove plate 102 is symmetrically provided with sliding grooves 5, the pressure claw 103 is rotatably mounted on the rotating shaft plate 104 via the first rotating shaft 105, the second rotating shaft 106 is rotatably connected to the pressure claw 103, and one end of the top of the second rotating shaft 106 is located in the sliding groove 5.

[0032] Furthermore, a second bearing 6 is rotatably mounted on the claw arm of the pressure claw 103.

[0033] Furthermore, there are two first bearings 2022, and a spacer 7 is provided between the two first bearings 2022.

[0034] Furthermore, the first magnetic block 2014 is embedded and fixed on the upper end face of the bearing seat 2012, and the second magnetic block 2025 is embedded and fixed on the lower end face of the outer sleeve 2021.

[0035] Furthermore, four of each of the first magnetic blocks 2014 and the second magnetic blocks 2025 are arranged at equal angles, and all of them have a cylindrical structure.

[0036] Furthermore, the drive device 101 is one of a cylinder, a hydraulic cylinder, an electric cylinder, or a linear motor.

[0037] Furthermore, the drive device 101 is one of a cylinder, a hydraulic cylinder, an electric cylinder, or a linear motor.

[0038] Working principle: During feeding, the drive device 101 operates, acting on the pressure claw 103 through the V-groove plate 102. The pressure claw 103 engages in the triangular groove 3, at which point the passive rotation mechanism 202 stops rotating. The square bar is manually or by a robotic arm fed into the square hole 4 on the second feeding shaft 2024. The square bar moves downwards within the square hole 4 due to its own gravity. When the drive device 101 resets, it loses the restraint of the pressure claw 103. The rotating active rotation mechanism 201 and the passive rotation mechanism 202 are connected by the first magnetic block 2014 and the second magnetic block 2015. The first magnetic block 2014 and the second magnetic block 2015, which are axially magnetized (with N and S poles distributed at both ends), will have their magnetic lines of force closed axially when opposite poles are aligned. After attraction, they still maintain a cylindrical structure. Therefore, when the active rotation mechanism 201 and the passive rotation mechanism 202 are connected, the square holes 4 on the first feeding shaft 2013 and the second feeding shaft 2024 are completely aligned without misalignment. To achieve continuous aligned conveying of square bars.
