[0001] This utility model relates to the technical field of walnut box processing equipment, and more specifically to a walnut box rope threading machine. Background Technology

[0002] A trellis box is a type of packaging box used to package various products. To facilitate handling, a drawstring is threaded through the trellis box, making it easier to carry. Currently, drawstring threading machines that can process paper bags exist on the market. However, trellis boxes are generally made of rigid cardboard and are stored in a staggered folded state. Therefore, during drawstring threading, the trellis box needs to be opened along the folding direction first, and then punched and threaded while remaining open. After threading, it needs to be folded back. Existing technology includes, for example, a trellis box drawstring threading machine disclosed in CN118386607A, which uses a first and second indexing plate to process the front and back sides of the trellis box respectively. However, the overall size of the equipment is large, which is inconvenient. Therefore, this application proposes a trellis box drawstring threading machine with an alternative structure.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] This embodiment discloses a walnut box rope threading machine, as shown in Figure 1. It includes a feeding channel 1, and a feeding mechanism 2, a punching mechanism 3, a rope threading mechanism 4, and a storage mechanism 5 are arranged sequentially along the feeding direction of the feeding channel 1. Referring to Figures 2-3, the feeding mechanism 2 includes a storage rack 21, a picking mechanism 22, and a box opening mechanism 23. The storage rack 21 is used to store folded walnut boxes that need to be threaded. One end of the storage rack 21 is provided with a discharge port, and the other end is provided with a push plate. The push plate continuously pushes the walnut boxes toward the discharge port. The material handling mechanism 22 delivers the walnut boxes stored on the storage rack 21 to the box opening mechanism 23. The box opening mechanism 23 opens the walnut boxes. The feeding channel 1 is provided with a first transfer component 11 and a second transfer component 12. The first transfer component 11 is used to pick up the walnut boxes after they have been opened and move them to the punching mechanism 3 and the rope threading mechanism 4 while keeping them open. The second transfer component 12 is used to fold the walnut boxes after they have been threaded and move them to the storage mechanism 5.

[0037] The box-opening mechanism 23 includes a first suction cup 231, a second suction cup 232, and a driving mechanism 233 that drives the first suction cup 231 to open the box. The first suction cup 231 and the second suction cup 232 respectively adhere to the front and back sides of the walnut box. The walnut box has four sides, of which the left and right sides are parallel and the front and back sides are parallel. Generally, the front and back sides are larger in size, and drilling and threading are done on the front and back sides. The front and back sides mentioned in this embodiment correspond to the front and back sides of the walnut box. The driving mechanism 233 drives the first suction cup 231 away from the second suction cup 232, so that the front and back sides of the walnut box are pulled apart to open the walnut box. Referring to Figure 4, the specific opening method of the box is as follows: the valence box 7 is in a folded state. The first suction cup 231 adheres to the front of the valence box 7, and the second suction cup 232 adheres to the back of the valence box 7. Then, the second suction cup 232 remains stationary, while the first suction cup 231 moves in the direction of the diagonal arrow in Figure 4, gradually moving away from the second suction cup 232, thus opening the valence box 7. The above structure solves the opening action of the valence box from a folded state to an open state, making the drawstring threading machine applicable to valence boxes. It should be noted that the punching mechanism 3 and the drawstring threading mechanism 4 are existing technologies. The punching mechanism and drawstring threading mechanism used in paper bag processing are the same, and will not be described again in this embodiment.

[0038] The drive mechanism 233 of the present invention has two embodiments depending on its structure:

[0039] Example 1: Referring to Figure 3, the drive mechanism 233 includes a horizontal moving component 2331 and a vertical moving component 2332. The horizontal moving component 2331 is a slide rail slider and a gear and rack mechanism arranged laterally along the conveying direction, which drives the horizontal movement through the gear and rack. The vertical moving component 2332 is a slide rail slider and a gear and rack mechanism arranged vertically and perpendicular to the conveying direction, which also drives the vertical movement through the gear and rack. The drive gear is a servo motor, which can flexibly control the rotation angle. In this way, the horizontal and vertical movements can be combined to achieve oblique movement. That is, the first suction cup component 231 achieves oblique movement through the combined action of the horizontal moving component 2331 and the vertical moving component 2332.

[0040] Example 2: Referring to Figure 5, the drive mechanism 233 includes a tilting component 2333, which drives the first suction cup component 231 to move obliquely. The tilting component is directly set as an oblique slide rail, and can also be driven by a gear and rack (not shown in the figure).

[0041] Furthermore, referring to Figure 4, the oblique moving direction of the first suction cup 231 is at a 45-degree angle to the conveying direction of the walnut box. Since the walnut box forms a rectangle inside after it is opened, with adjacent surfaces at a 90-degree right angle, the optimal way to open it is to open it obliquely at a 45-degree angle.

[0042] Further, referring to Figure 2, the material handling mechanism 22 includes a material handling suction cup frame 221 and a feeding clamp 222. The material handling suction cup frame 221 is located at the outlet of the storage rack 21 and removes the walnut box. The feeding clamp 222 is used to receive the walnut box removed by the material handling suction cup frame 221 and send it to the box opening mechanism 23. Specifically, the suction cup frame 221 can pull the walnut box outward after it is suctioned by a cylinder or other components, so that the walnut box moves out of the outlet of the storage rack. Then, the feeding clamp 222 can clamp the walnut box by a cylinder, and then the walnut box is reciprocated by a linear motor.

[0043] Furthermore, as another embodiment of the box-opening mechanism 23, referring to FIG10, the box-opening mechanism 23 includes a pair of box-opening push plates 234 that can move back and forth and approach each other (the back and forth movement and approaching each other can be achieved by existing technologies such as cylinders or slide rails). The pair of box-opening push plates 234 correspond to the left and right sides of the walnut box respectively. First, the box-opening push plates 234 move forward to the sides of the walnut box and abut against the left and right sides of the walnut box. Then, the box-opening push plates approach each other or approach one side, causing the left and right sides of the walnut box to form a perpendicular angle with the front and rear sides, thereby opening the walnut box. Then, the walnut box is held by the subsequent first transfer component 11. After the box-opening push plates 234 are reset, the walnut box can be transported away. Meanwhile, if this embodiment is adopted, the box opening mechanism 23 can be set at the material picking suction cup frame 221. The suction cup 235 that adsorbs the walnut box in Figure 10 can be the material picking suction cup frame 221. In this way, there is no need to set up an additional suction cup, and the box can be opened at the same time as picking up the material. However, this requires further adjustment of the structure of the feeding clamp 222 so that it is adsorbed on the front and back sides of the walnut box like the first transfer component 11, rather than clamping the walnut box. Alternatively, the length of the first transfer component 11 and the interval between the working positions of each mechanism of the rope threading machine can be adjusted, and the feeding clamp can be omitted so that after the material picking suction cup frame 221 picks up the material and opens the box, it can be directly transported by the first transfer component 11.

[0044] Furthermore, referring to Figures 1 and 6-7, the feeding channel 1 is provided with a first transfer component 11 and a second transfer component 12. The first transfer component 11 is used to receive the opened box and move it to the punching mechanism 3 and the threading mechanism 4. The second transfer component 12 is used to fold the threaded box back and move it to the storage mechanism 5. Specifically, in Figure 6, the first transfer component 11 includes a first moving plate 111 located on both sides of the feeding channel 1 and reciprocating between the box opening mechanism 23, the punching mechanism 3 and the threading mechanism 4. Suction cup clamps 112 are provided at both ends of the first moving plate 111. One end of the suction cup 112 moves the walnut box from the box-opening mechanism 23 to the punching mechanism 3, while the other end of the suction cup 112 moves the walnut box from the punching mechanism 3 to the threading mechanism 4. The first moving plate 111 is driven by a linear motor, and the distance between the suction cups 112 at both ends is exactly matched with the distance between the box-opening mechanism 23 and the punching mechanism 3, as well as the distance between the punching mechanism 3 and the threading mechanism 4. Thus, when moving the walnut box, firstly, the suction cup 112 near the lower right side of the figure (near the box-opening mechanism 23) first picks up the walnut box 7 after it has been opened. Then, the linear motor drives the first moving plate 111 to move, allowing the walnut box to be transported to the punching mechanism 3. Then, the suction cup component on the punching mechanism 3 picks up the delivered walnut box. 12. Release the walnut box and return to the box opening mechanism to pick up the next walnut box that has been opened. At this time, the suction cup 112 on the upper left side of the figure (near the rope threading mechanism) can just hold the walnut box that is being punched at the punching mechanism 3. After the punching is completed, one end of the first moving plate 111 just moves the newly opened walnut box at the box opening mechanism to the punching mechanism 3. The other end of the first moving plate 111 moves the walnut box that has been punched at the punching mechanism 3 to the rope threading mechanism 4 for rope threading. The rope threading mechanism 4 also has a suction cup component that can hold the delivered walnut box. In this way, the reciprocating movement of the first moving mechanism 11 continuously sends the walnut box from the box opening mechanism 23 to the punching mechanism 3, and then sends the walnut box at the punching mechanism 3 to the rope threading mechanism.

[0045] Furthermore, referring to Figures 7-8, the second transfer component 12 includes a second moving plate 121 located on both sides of the feeding channel 1 and reciprocating between the rope threading mechanism 4 and the storage mechanism 5. Both ends of the second moving plate 121 are provided with flat clamps 122. The second moving plate 121 reciprocates via a linear motor. One side of the second moving plate 121 has an arc-shaped impact plate 6 at the end near the rope threading mechanism 4. The arc-shaped impact plate 6 is used to collide with the side of the walnut box to guide the walnut box to refold. Referring specifically to Figure 8, after the rope threading mechanism 4 completes the rope threading, the suction cup component on one side of the arc-shaped impact plate 6 releases first, while the other side remains suctioned, as shown in the left side of the walnut box in Figure 8. Then, the arc-shaped impact plate 6 collides with the side of the walnut box 7 in the direction of the arrow, causing the walnut box 7 to fold back to the state shown on the right side of Figure 8. At this time, the flat clamp 122 can clamp towards the middle, refolding and clamping the walnut box that has completed the rope threading process. After all the suction cup components of the rope threading mechanism 4 are released, the second transfer component 121 can clamp the walnut box and transfer it to the next work station. Preferably, one side of the second moving plate 121 on both sides has the arc-shaped impact plate 6, and the other side can be provided with an inclined guide plate on the flat clamp 122 to assist the walnut box in entering the clamping opening of the flat clamp 122.

[0046] Furthermore, to facilitate the conveying of the walnut boxes in the overall equipment, referring to Figure 9, the receiving mechanism 5 includes a discharge port 51 and a conveyor belt 52. A pair of guide plates 511 and a stopping gripper 512 located above the guide plates 511 are provided at the discharge port 51. The stopping gripper 512 is used to hold the walnut box at the discharge port 51. Specifically, the second transfer component 12 first refolds the walnut box after it has been threaded with rope using the arc-shaped impact plate 6. Then, the second transfer component 12 moves the walnut box to the stopping gripper 512, where it is held and stopped. At this time, the flat clamp at this end of the second transfer mechanism 12... Release 122 and return to the rope-threading mechanism 4 to prepare to clamp the next valen box that has been threaded. At this time, one end of the rear end of the second transfer mechanism 12 (near the conveyor belt 52) ​​just reaches the stopping gripper 512. At this time, both ends of the flat clamp 122 are clamped, the stopping gripper 512 is released, and then the second moving plate 121 moves. One end of the flat clamp 122 sends the valen box at the rope-threading mechanism 4 to the stopping gripper 512. The valen box at the stopping gripper 512 is moved above the conveyor belt 52 by the other end of the flat clamp 122. After being released, the valen box falls onto the conveyor belt 52, achieving sorting and storage. In the enlarged view of Figure 9, the stopping gripper 512 is set as a cylinder gripper that can open or close. The gripping position can be equipped with suction cups or other devices to increase the stability of the gripping. At the same time, the guide plate 511 is used to guide the folded valen box to keep it in a folded state. The entrance of the guide plate 511 is provided with a funnel shape to facilitate the guidance of the valen box into the folded box. Finally, it should be clarified that in the embodiments of this application, the suction cup clamp, the material-picking suction cup frame, the first suction cup component, the second suction cup component, and the suction cup components of the punching mechanism and the rope-threading mechanism are all combinations of telescopic cylinders and suction cup components. The cylinders are used to achieve proximity to the walnut box or width adjustment, and the suction cups are responsible for adsorbing the walnut box.

[0047] 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.
