[0031] Figures 1-3 The diagram shown is a structural schematic of the first embodiment of an L-shaped carton flipping mechanism according to this utility model. Please refer to [link / reference]. Figures 1-3 The L-shaped carton flipping mechanism of this embodiment includes a main body 100 and a power assembly 200.

[0032] A sliding rod 110 is installed on the inner side of the fixed base 100. A movable base 120 is installed on the sliding rod 110. The movable base 120 can slide along the axial direction of the sliding rod 110. A bearing seat 130 is installed on the movable base 120. A rotating bearing 140 is provided inside the bearing seat 130. A shaft 150 is installed on the rotating bearing 140. The shaft 150 rotates with the bearing seat 130 with low friction through a rolling bearing. A tilting frame 160 is installed on the shaft 150. A buffer frame 170 is installed on the inner side of the tilting frame 160. An electric telescopic rod 180 is provided at the end of the tilting frame 160. The telescopic end of the electric telescopic rod 180 is fixedly connected to the movable frame 190. The movable frame 190 moves linearly with the extension and retraction of the electric telescopic rod 180.

[0033] The power assembly 200 includes a motor mounting bracket 210, which is a U-shaped steel structure. A drive motor 220 is mounted on the motor mounting bracket 210. The drive motor 220 is a servo motor with forward and reverse rotation functions and speed adjustment capability. The output end of the drive motor 220 is connected to a ball screw 230 via a coupling. The ball screw 230 is connected to a connecting frame 240. An adapter seat 250 is provided on the side of the motor mounting bracket 210. An adjustable connecting rod 260 is mounted on the adapter seat 250. The adjustable connecting rod 260 has a two-section structure, and its length can be finely adjusted by adjusting the middle bolt. The other end of the adjustable connecting rod 260 is connected to the tilting frame 160 via the adapter seat 250.

[0034] There are two fixed seats 100, which are fixedly connected to both sides of the conveyor belt. The bottom of the fixed seat 100 is provided with a waist-shaped hole, which can be used to make fine adjustments to the position by bolts to the conveyor belt frame. There are two sliding rods 110, which are located on the inner walls of both ends of the fixed seat 100. The surface of the sliding rods 110 is chrome-plated to reduce the frictional resistance when the moving seat 120 slides.

[0035] The tilting frame 160 has an L-shaped structure and is made of aluminum alloy in one piece, combining strength and lightweight characteristics. The buffer frame 170 is located inside the vertical part of the tilting frame 160 and is connected to the tilting frame 160 through a spring rod. The spring rod is covered with a rubber protective sleeve to prevent the spring from rusting. The electric telescopic rod 180 is located at the end of the horizontal part of the tilting frame 160. The cylinder of the electric telescopic rod 180 is fixed to the tilting frame 160 through a flange. A guide rod 181 is also installed between the tilting frame 160 and the movable frame 190. The guide rod 181 is located above and below the electric telescopic rod 180. A linear bearing is provided at the connection between the guide rod 181 and the movable frame 190 to ensure the straightness of the movement of the movable frame 190.

[0036] The connecting bracket 240 is fixed to the bottom of the bearing seat 130 and is fixed to the moving part of the ball screw 230 by bolts. The two ends of the ball screw 230 are connected to the motor mounting bracket 210 through the bearing seat 130. The ball screw 230 is covered with a dust cover to prevent dust from entering and affecting the screw transmission accuracy.

[0037] There are two adapter seats 250, located on both sides of the motor mounting bracket 210, and fixed to the fixed base 100 by welding. The connecting hole of the adapter seat 250 is provided with a copper sleeve to reduce the wear of the adjustable connecting rod 260 when it rotates.

[0038] Both ends of the adjustable connecting rod 260 are rotatably connected to the adapter 250 via pins. The adapter 250, which is close to the tilting frame 160, is rotatably connected to the tilting frame 160 via a mounting shaft. A thrust bearing is provided at the connection between the mounting shaft and the tilting frame 160 to withstand the axial force generated during the tilting process.

[0039] Combination Figures 1-3 The working principle of an L-shaped carton flipping mechanism in this embodiment is as follows:

[0040] (a) Initial state positioning

[0041] When the mechanism is not activated, the tilting frame 160 remains horizontal. The movable frame 190 is positioned at the end of the horizontal section of the tilting frame 160 under the retraction of the electric telescopic rod 180, forming an open L-shaped receiving space with the vertical section of the tilting frame 160, waiting for the carton to enter. The adjustable connecting rod 260 is at its initial length, and both ends are stably connected to the motor mounting frame 210 and the tilting frame 160 respectively through the adapter seat 250. The movable seat 120, bearing seat 130 and shaft 150 are all in the initial position of the sliding rod 110, ensuring that the L-shaped groove of the tilting frame 160 is aligned with the conveyor belt conveying path, preparing for the precise entry of the carton.

[0042] (ii) Carton positioning and clamping power transmission

[0043] When the conveyor belt transports the carton to the entrance of the flipping frame 160, the front end of the carton triggers the photoelectric sensor, and the conveyor belt stops running. The carton then falls precisely into the L-shaped groove of the flipping frame 160, completing its positioning. At this time, the electric telescopic rod 180 receives a clamping command, and its telescopic end extends axially, providing stable support through the fixed end connected by a flange. This drives the movable frame 190 to move linearly along the guide rod 181 (the guide rod 181 ensures that the movable frame 190 moves without deviation through a linear bearing). As the movable frame 190 approaches the carton, the side wall of the carton first contacts the buffer frame 170 inside the flipping frame 160. The buffer frame 170 generates an adaptive clamping force through the elastic deformation of the spring rod until the movable frame 190 is in close contact with the other side of the carton, forming a three-point stable clamping structure of "buffer frame 170 - carton - movable frame 190," preventing the carton from shifting or deforming during the flipping process.

[0044] (III) Power transmission and motion conversion during flipping

[0045] After clamping is completed, the drive motor 220 (servo motor) receives the flipping command, and its output end transmits torque to the ball screw 230 through the coupling, causing the ball screw 230 to rotate uniformly around its own axis. Since the moving part of the ball screw 230 is fixed to the connecting frame 240, and the connecting frame 240 is rigidly connected to the bottom of the bearing seat 130, the rotational motion of the ball screw 230 is converted into the linear motion of the connecting frame 240 along the screw axis, which in turn causes the bearing seat 130 and the moving seat 120 to slide smoothly along the sliding rod 110 (the sliding rod 110 is chrome-plated to reduce frictional resistance and ensure smooth movement).

[0046] Simultaneously, the adjustable connecting rod 260 connected to the flipping frame 160 functions: one end of the adjustable connecting rod 260 is rotatably connected to the fixed motor mounting bracket 210 via the adapter 250, and the other end is rotatably connected to the flipping frame 160 via the adapter 250. When the moving seat 120 drives the flipping frame 160 to move along the sliding rod 110 with the bearing seat 130, the adjustable connecting rod 260 undergoes a change in tilt angle due to the rotational constraints at both ends, applying a rotational torque around the shaft 150 to the flipping frame 160. The shaft 150 achieves low-friction rotation through the rolling bearing in the bearing seat 130, providing a stable rotational fulcrum for the flipping frame 160, ultimately converting the linear motion of the moving seat 120 into the rotational motion of the flipping frame 160 around the shaft 150, thus realizing the flipping action of the carton.

[0047] During this process, the speed of the servo motor can be adjusted according to the characteristics of the carton (e.g., low speed for fragile items) to ensure stable flipping torque; the length of the adjustable connecting rod 260 can be finely adjusted through the middle bolt to change the rotation radius of the flipping frame 160, thereby precisely controlling the flipping angle (adjustable within the range of 0-90°) to meet different process requirements.

[0048] (iv) Reset and release after flipping

[0049] When the flipping frame 160 rotates to a preset angle (e.g., 90°), the servo motor stops rotating and maintains its current position, ensuring the carton remains stable for subsequent processes. After the subsequent processes complete the carton retrieval preparation, the electric telescopic rod 180 retracts first, driving the movable frame 190 back to its initial position along the guide rod 181, releasing the clamp on the carton; then the servo motor reverses, driving the connecting frame 240, bearing seat 130, and movable seat 120 to move in the opposite direction along the sliding rod 110 via the ball screw 230. The adjustable connecting rod 260 gradually returns to its initial angle as the movable seat 120 resets, driving the flipping frame 160 to rotate in the opposite direction around the shaft 150 to a horizontal state; finally, all components return to their initial positions, waiting for the next carton to enter, completing one flipping cycle.
