Description

Technical Field

[0001] This utility model relates to the field of transmission belt conveying, and specifically to a folding type transmission belt conveying device. Background Technology

[0002] Conveyor belts, also known as transport belts, are rubber, fiber, and metal composite products used in belt conveyors to carry and transport materials. Belt conveyors offer continuous, high-efficiency, and steep-angle transport capabilities, are safe to operate, and have low transportation costs, making them widely used in various applications.

[0003] Existing conveyor belts are generally of a fixed structure, meaning the conveyor belt connects between the driving and driven pulleys, and the mounting frame is fixed. This fixed frame cannot be folded to reduce space, resulting in a large footprint when idle or under maintenance. Furthermore, conveyor belts are typically used in conjunction with other robotic arms, whose placement of metal objects is often not fixed. This means that the metal objects leave the conveyor belt in various positions, hindering their ability to be grasped by the robotic arm in subsequent processes. Utility Model Content

[0004] In view of the existing technical problems, this utility model provides a foldable conveyor belt conveying device to solve the problems in the prior art.

[0005] To achieve the above-mentioned utility model objectives, the present utility model provides the following technical solution: a folding conveyor belt conveying device, comprising a fixed frame, a movable frame, and a conveyor belt, wherein: a connecting plate is symmetrically provided on both sides of the near portion of the fixed frame and the movable frame, the two connecting plates are fixedly connected to the fixed frame, and the two connecting plates are hinged to the movable frame through a pin, so that the movable frame can rotate around the pin; a locking structure is provided between the connecting plate and the movable frame, the locking structure is used to lock the position of the movable frame, when the movable frame rotates to be on the same straight line as the fixed frame or rotates above the fixed frame, the locking structure can lock the position of the movable frame in these two states;

[0006] The conveyor belt is wrapped around the drive pulley and the driven pulley. These two pulleys are respectively installed at the ends of the fixed frame and the movable frame. The drive pulley rotates under the drive of the drive motor, thereby driving the conveyor belt to rotate.

[0007] In this case, the fixed frame is provided with two positioning blocks at the end away from the movable frame. These two positioning blocks are located above the upper half of the conveyor belt, and the near ends of the two positioning blocks are suspended in the air. The far ends of the two positioning blocks are connected to the fixed frame in an adjustable manner, thereby adjusting the relative angle of the positioning blocks so as to perform coarse positioning of the items conveyed on the conveyor belt.

[0008] In this case, the locking structure includes a locking pin and a safety pin. The pin is fixed side by side to the end of the movable frame near the fixed frame. The two connecting plates are symmetrically provided with locking grooves a and safety grooves b with top openings. When the movable frame rotates to be on the same straight line as the fixed frame, the locking pin slides into the locking groove a and the safety pin slides into the safety groove b. When the movable frame is flipped into place, the locking pin abuts against the top surface of the connecting plate, and the safety pin is located outside the safety groove b.

[0009] In this case, the fixed frame is symmetrically provided with a negative electrode block and a positive electrode block at its end. The negative electrode block is directly fixed to the fixed frame, and the positive electrode block is fixed to the fixed frame through an insulating block. When a metal object is coarsely positioned by the two positioning blocks, it is precisely positioned and blocked when it passes through these two blocks. The negative electrode block and the positive electrode block are respectively connected to the PLC through wires. The control signal of the PLC is used to control the drive motor to stop or the robot arm to grab the metal object on the conveyor belt.

[0010] In this case, the fixed frame is fixedly supported on the ground by a support frame, and the active pulley is located on the fixed frame.

[0011] Beneficial effects: The movable frame of this utility model can rotate and fold up when the machine is stopped, thereby greatly reducing the floor space occupied. When unfolded, it can transport metal objects normally. At the same time, this device can position the items transported on the conveyor belt so that the robot arm can grasp them.

[0016] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0017] As attached Figure 1 - Appendix Figure 4The folding conveyor belt conveying device shown mainly includes a fixed frame 1 and a conveyor belt 5. A connecting plate 3 is symmetrically provided on both sides of the fixed frame 1 and the movable frame 2 near the fixed frame 1. The two connecting plates 3 are fixedly connected to the fixed frame 1. The fixed frame 1 is fixedly supported on the ground by a support frame.

[0018] Two connecting plates 3 are hinged to the movable frame 2 via pins 4, allowing the movable frame 2 to rotate around the pins 4, thereby rotating the movable frame 2 relative to the fixed frame 1. A locking structure is provided between the connecting plates 3 and the movable frame 2 to lock the position of the movable frame 2. When the movable frame 2 rotates to be on the same straight line as the fixed frame 1 or rotates above the fixed frame 1, the locking structure can lock the position of the movable frame 2 in these two states.

[0019] The locking structure includes a locking pin 9 and a safety pin 10. These two pins are fixed side by side to the end of the movable frame 2 near the fixed frame 1. The two connecting plates 3 are symmetrically provided with locking grooves 3a and safety grooves 3b with top openings. When the movable frame 2 rotates to be on the same straight line as the fixed frame 1, the locking pin 9 slides into the locking groove 3a and the safety pin 10 slides into the safety groove 3b. When the movable frame 2 is flipped into place, the locking pin 9 abuts against the top surface of the connecting plate 3 and the safety pin 10 is located outside the safety groove 3b.

[0020] As attached Figure 1 - Appendix Figure 4 As shown, the conveyor belt 5 wraps around the driving pulley 6 and the driven pulley 7. These two pulleys are respectively installed at the ends of the fixed frame 1 and the movable frame 2. The driving pulley 6 rotates under the drive of the drive motor 20, thereby driving the conveyor belt 5 to rotate. In this case, both the driving pulley 6 and the drive motor 20 are located on the fixed frame 1, which helps to reduce the load on the movable frame 2.

[0021] Two positioning blocks 8 are provided at the end of the fixed frame 1 furthest from the movable frame 2. These two positioning blocks 8 are located above the upper half of the conveyor belt 5, with the near ends of the two positioning blocks 8 suspended in the air. The far ends of the two positioning blocks 8 are adjustablely connected to the fixed frame 1, thereby adjusting the relative angle of the positioning blocks 8 for coarse positioning of the items conveyed on the conveyor belt 5. The connection between the positioning blocks 8 and the fixed frame 1 can be varied, the simplest being a screw connection. After the positioning blocks 8 are adjusted to the correct position, the screws are tightened.

[0022] The fixed frame 1 is symmetrically provided with a negative electrode block 11 and a positive electrode block 12 at its end. The negative electrode block 11 is directly fixed to the fixed frame 1, and the positive electrode block 12 is fixed to the fixed frame 1 through an insulating block 13. When a metal object is coarsely positioned by the two positioning blocks 8, it is precisely positioned and blocked when it passes through these two blocks. The negative electrode block 11 and the positive electrode block 12 are respectively connected to the PLC through wires. The control signal of the PLC is used to control the drive motor 20 to stop or the robot to grab the metal object on the conveyor belt 5.

[0023] The working principle of this utility model is as follows: When the movable frame 2 rotates to be on the same straight line as the fixed frame 1, the locking pin 9 slides into the locking groove 3a and the safety pin 10 slides into the safety groove 3b. In this state, the device is in normal use. When the movable frame 2 is flipped into place, the locking pin 9 abuts against the top surface of the connecting plate 3 and the safety pin 10 is located outside the safety groove 3b. In this case, the device is in the folded state.

[0024] In normal use, the drive motor 20 is started, which drives the conveyor belt 5 to rotate. The metal object on the conveyor belt 5 moves from the movable frame 2 to the fixed frame 1. When the metal object moves to the two positioning blocks 8, it is coarsely positioned. Then, when it moves to the negative pole block 11 and the positive pole block 12, it is blocked by the negative pole block 11 and the positive pole block 12, and the signal is connected. This enables the PLC to obtain a control signal, which controls the drive motor 20 to stop or the robot arm to grab the metal object on the conveyor belt 5.
