[0060] Embodiment 2:

[0061] The following is the working principle of the fully automatic conveying device for the sweeping machine brush head of the present invention:

[0062] like Figure 1-3 As shown, Figure 1 This is a structural diagram of the reciprocating transfer mechanism of the present invention before loading. Figure 2 This is a structural diagram of the reciprocating transfer mechanism of the present invention after loading. Figure 3 It is a structural diagram of the tightening mechanism of the present invention.

[0063] Figure 1-2In the figure, point D is the material collection point, points A, A1, B, B1, C and C1 are all transfer points, and point E is the material discharge point. Among them, points A1, B and B1 are processing points, and points A1, B and B1 are also the clamping points of the push mechanism. That is, when the sweeper brush head 20 reaches the three processing points of points A1, B and B1, it will be clamped by the push mechanism for processing.

[0064] Initial state: when the sweeping machine brush head 20 to be processed is sent to point D, at this time, the sweeping machine brush head 20 is between the opened mechanical claws 111, and the mechanical claws 111 close to clamp the two ends of the sweeping machine brush head 20.

[0065] The first motor 1 drives the reducer 2 to work, the reducer 2 drives the screw rod 4 to rotate counterclockwise, and the screw rod 4 drives the nut 3 to rotate in the Figure 1 The nut 3 drives the connecting plate 14 on the right to move to the left, and the connecting plate 14 on the right drives the movable plate 13 to move to the left along the double-row guide rails 16. The five clamping devices move leftward from points A1, B, B1, C and C1 to the corresponding points A, A1, B, B1 and C, respectively, and the five clamping devices are all in an open state.

[0066] At this time, the connecting rod assembly 5 on the left side drives the pulley group to work, and the movable wheel 11 on the pulley group turns 180 degrees to just above point A. Since the passive wheel 9 synchronously drives the movable wheel 11 to rotate, the movable wheel 11 rotates 360 degrees, driving the mechanical claw 111 to rotate 360 ​​degrees as well, so that the sweeping machine brush head 20 on the mechanical claw 111 is sent to point A (such as Figure 2 shown).

[0067] The clamping device at point A clamps the sweeper brush head 20, and the left mechanical claw 111 opens. The first motor 1 drives the reducer 2 to move in the reverse direction, and through the transmission mechanism, the left mechanical claw 111 returns to the Figure 1 The state diagram in .

[0068] When the second sweeping machine brush head 20 is sent to point A, the first sweeping machine brush head 20 is synchronously sent to point A1. Since point A1 has a pushing mechanism, the pushing mechanism clamps the first sweeping machine brush head 20 at point A1, and the clamping device at point A1 opens.

[0069] After multiple actions are continued, there are sweeping machine brush heads 20 at points A1 and B1, and the push mechanism clamps the sweeping machine brush heads 20 at points A1 and B1, and the sweeping machine brush heads 20 at points A1 and B1 are processed by external processing equipment. Since the push mechanism is provided with a rotating device, the sweeping machine brush heads 20 at points A1 and B1 can perform circular surface processing.

[0070] When the sweeping machine brush head 20 at point C is processed, the sweeping machine brush head 20 is completely processed and then transmitted to the right again. The sweeping machine brush head 20 at point C reaches point C1. Finally, the mechanical claw on the right grabs the sweeping machine brush head 20 from point C1 and sends it to point E, and then sends it to the transmission equipment of the next process.

[0071] The above transmission action of the sweeping machine brush head 20 is a continuous action, which greatly improves the processing efficiency of the sweeping machine brush head 20.

[0072] In summary, the present invention improves the traditional transmission method, and carries the sweeper brush head through a reciprocating transfer mechanism, with precise positioning and high efficiency in moving the sweeper brush head. The manipulator designed by the present invention cleverly uses multiple pulleys to drive the mechanical claw, so that the mechanical claw moves with the movable wheel while rotating, thereby realizing the flipping action of the mechanical claw. The tightening mechanism of the present invention can tighten the sweeper brush head and drive the sweeper brush head to rotate, so that the circumferential surface of the sweeper brush head can be processed.

[0073] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
