[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] This embodiment discloses a conveying mechanism for a walnut box rope threading machine, such as... Figure 1-4 As shown, it includes a frame 1, on which a conveyor channel 2 for conveying walnut boxes is provided, and the frame 1 also includes:

[0038] Mounting bracket 3 is slidably mounted on the frame 1 on both sides of the conveying channel 2;

[0039] Adjustment drive mechanism 4 is used to drive and adjust the distance between the two mounting brackets 3 on both sides;

[0040] The conveying component 5 is slidably mounted on the conveying frame 3 and reciprocates along the conveying direction of the conveying channel 2;

[0041] The movable box-opening component 6 is mounted on the conveying component 5 at one end and connected to the walnut box at the other end for transferring the walnut box.

[0042] In the above structure, the components that need to be adapted to the width of the walnut box are integrated on the mounting frame 3. Then, by adjusting the drive mechanism 4, the overall mechanism can be adapted to the width of the walnut box by controlling the spacing of the mounting frames 3 on both sides of the conveying channel 2. The adjustment is very convenient.

[0043] Further reference Figure 2-3 The specific adjustment drive mechanism 4 includes:

[0044] The support base 401 is fixedly mounted on the frame 1 at its lower part and slidably connected to the mounting bracket 3 at its upper part via a slide rail slider component;

[0045] Rotate the lead screw 402, which is rotatably mounted on the frame 1 and parallel to the slide rail on the support 401. The lead screw 402 is driven to rotate by the servo motor 404.

[0046] The lead screw nut 403 is fixedly mounted on the mounting bracket 3 and is threadedly connected to the rotating lead screw 402.

[0047] In the above structure, the support base 401 and the slide rail slider on it play a supporting role, the rotating screw 402 and the screw nut 403 play a role in controlling the movement, the servo motor 404 can precisely control the rotation angle, and combined with the pitch of the rotating screw 402, the distance of movement can be calculated by relying on the existing program. Thus, by inputting the required adjustment distance or the width of the valence box into the controller, the automatic adjustment of the adjustment drive mechanism 4 can be realized, which is convenient to use.

[0048] Furthermore, this embodiment also includes:

[0049] The fixed opening component 7 is fixedly mounted on the mounting bracket 3 at one end and connected to the walnut box at the other end, used to fix the walnut box in its current position. In the above structure, after the moving opening component 6 moves the walnut box to the corresponding position, the fixed opening component 7 fixes the walnut box, so that the walnut box can remain in the open state to realize subsequent drilling and rope threading processing.

[0050] Furthermore, refer to Figure 4 The conveying component 5 includes:

[0051] Track 501 is fixedly mounted on mounting frame 3 along the conveying direction of conveying channel 2;

[0052] The transfer plate 502 is slidably disposed above the track 501, and the movable box opening component 6 is disposed on the transfer plate 502;

[0053] A timing belt 503 is mounted on the mounting frame 3 and is parallel and adjacent to the track 501. A connecting block 5021 is provided on the transfer plate 502 to connect with the timing belt 503.

[0054] The power source 504 is mounted on the mounting bracket 3 and is used to drive the synchronous belt 503 to rotate.

[0055] With the above structure, the power source 504 is set as a servo motor for convenient and precise control. Several sliders are provided between the transfer plate 502 and the track 501 to support the transfer plate 502 to slide on the track 501. The connecting block 5021 on the transfer plate 502 can be directly connected to the transfer plate 502, or it can extend from one of the sliders and be clamped to the toothed structure on the timing belt 503 through a clamping plate, so that the transfer plate 502 can move together when the timing belt 503 moves.

[0056] Furthermore, both the movable opening component 6 and the fixed opening component 7 include:

[0057] Suction cup 8 is used to adhere to the end face of the walnut box to form a connection with the walnut box;

[0058] The telescopic cylinder 9 drives the suction cup component 8 to move closer to or away from the end face of the walnut box.

[0059] The suction cup 8 is connected to an external air source and uses negative pressure to suction the end face of the walnut box. When suction is needed, the telescopic cylinder 9 controls the suction cup 8 to move closer to the end face to form suction. When suction is not needed, the telescopic cylinder 9 controls the suction cup 8 to move away to avoid obstructing or interfering with the transport of the walnut box.

[0060] Furthermore, refer to Figure 1-2 Corresponding to the processing of the walnut box rope threading machine, the frame 1 is equipped with a receiving station 101, a punching station 102, a rope threading station 103, and a delivery station 104. Two sets of fixed box-opening components 7 are provided, located at the punching station 102 and the rope threading station 103 respectively. Further movement of the box-opening component 6 includes:

[0061] The first movable box opening component 61 is used to transfer the walnut box from the receiving station 101 to the punching station 102.

[0062] The second movable box opening component 62 is used to move the walnut box from the punching station 102 to the rope threading station 103;

[0063] The third moving box opening component 63 is used to transfer the walnut box from the rope threading station 103 to the delivery station 104.

[0064] With the above structure, in this embodiment, during operation, the first movable box-opening component 61 first receives the open walnut box from the storage rack (not shown in the figure) at the receiving station 101. Then, the first movable box-opening component 61 delivers the walnut box to the punching station 102. At this time, the fixed box-opening component 7 at the punching station 102 holds the delivered walnut box so that the punching mechanism (not shown in the figure) can perform the punching operation. Then, the first movable box-opening component 61 can release the walnut box and return to the receiving station 101 to receive the next walnut box. When the first movable box-opening component 61 returns to the receiving station, the second movable box-opening component 62 just arrives at the punching station 102 and holds the walnut box. After the valence box has been punched (the fixed opening component 7 at the punching station releases accordingly), it is sent to the rope threading station 103. The fixed opening component 7 at the rope threading station 103 holds the delivered valence box, facilitating the rope threading mechanism (not shown in the figure) to thread the rope. Then, the second moving opening component 62 releases the valence box and returns to the punching station 102 to pick up the next valence box. At this time, the third moving opening component 63 arrives at the rope threading station 103, holds the valence box that has been threaded (the fixed opening component 7 at the rope threading station releases accordingly), and then sends the valence box to the delivery station 104. Finally, the material handling mechanism (not shown in the figure) subsequently set at the delivery station 104 removes the valence box. This completes the conveying of one valence box. Through the coordinated conveying of the moving opening component 6 and the fixed opening component 7 in this embodiment, the valence box is always kept in an open state for convenient processing.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
