Description

Technical Field

[0001] This utility model relates to the technical field of cord threading equipment for walnut boxes, and more specifically to a high-speed walnut box opening device. Background Technology

[0002] Currently, the basic principle of opening a walnut box in existing technology is as described in the feeding mechanism of a walnut box threading machine disclosed in publication number CN222451534U. This mechanism relies on a guide plate structure, where the guide plate is positioned along the movement path of the walnut box and engages with the folded walnut box. When the walnut box moves towards the workstation, the guide plate pushes the splicing surface of the walnut box, causing it to switch from a folded to an open state. Existing technology essentially operates on this basic principle.

[0003] However, in actual use, it was found that after continuously increasing the processing speed of the equipment, the walnut box was prone to failure to open. After analysis, it was found that this was because the front and back of the folded walnut box were originally pressed together. When the folded walnut box was quickly removed, the front and back of the walnut box did not have enough time and space to separate, and the two sides were still adsorbed together. At this time, pushing the side (joint surface) of the folded walnut box could easily cause the walnut box to bend as a whole instead of opening, thus causing the box to fail to open. This problem occurred more frequently with walnut boxes that were relatively soft. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-speed opening device for walnut boxes, which can adapt to high-speed opening of walnut boxes, ensure stable opening of walnut boxes, and solve the problem of easy failure in opening at high speeds.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed box opening device for a folded box, comprising a feeding rack and an opening mechanism. The opening mechanism includes a picking component that removes the folded ...

[0006] The present invention is further configured such that there is a travel distance between the stop and the outlet of the feeder.

[0007] The present invention is further configured such that the stop member is a thin rod structure.

[0008] The present invention is further configured to include a crossbeam, on which an extension arm is provided, and the material stop is provided on the extension arm.

[0009] The present invention is further configured such that: a slide rail and a sliding seat that slides on the slide rail and is locked are provided on the crossbeam, and the extension arm is provided on the sliding seat.

[0010] The present invention is further configured such that: the extension arm is provided with a plurality of mounting positions, and the material stop is mounted on the mounting positions.

[0011] The present invention is further configured such that: a lifting mechanism is provided on the extension arm, and the extension arm is fixedly disposed on the lifting end of the lifting mechanism.

[0012] The present invention is further configured such that the crossbeam is positioned above or below the feeding rack.

[0013] The present invention is further configured such that: the box opening mechanism includes a side guide plate located on one side of the material taking part, and the side guide plate acts on the side of the folded Valen box to open the Valen box.

[0014] The present invention is further configured such that: a pair of side guide plates are provided, and the pair of side guide plates can move back and forth and move closer or further apart from each other.

[0015] In summary, this utility model has the following beneficial effects:

[0016] This invention incorporates a baffle that blocks the back of the folded walnut box during the material handling process. Combined with the material handling mechanism, this allows the front and back of the folded walnut box to separate before the opening mechanism officially opens it, thus pre-opening the walnut box. This prevents opening failures due to adhesion issues between the front and back of the walnut box during subsequent opening, resulting in a better and more stable opening effect. This design is suitable for high-speed conveying and opening of walnut boxes. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] For ease of understanding, please refer to Figure 4 , Figure 4 The Valen box shown at the top center is in a folded state. Its a side is defined as the front, b side as the back, and the two c sides on the left and right are defined as the sides. Unless otherwise specified, the front, back, and sides of the Valen box shall be defined as above.

[0029] This embodiment discloses a high-speed opening device for a walnut box, such as... Figure 1-8 As shown, the device includes a feeding rack 1 and a box-opening mechanism 2. The feeding rack 1 holds a plurality of folded walnut boxes. The box-opening mechanism 2 includes a picking component 201 that removes the folded walnut boxes from the feeding rack 1. A stop component 3 is provided along the path of the folded walnut box removal, acting on the back of the folded walnut box. The stop component 3 and the picking component 201 keep the back and front of the folded walnut box apart, thus achieving pre-opening of the walnut box. In high-speed operation, due to the high picking speed of the picking component 201 and the high opening speed of the box-opening mechanism 2, there is insufficient time and space for the front and back of the folded walnut box to slowly separate. Therefore, the stop component 3 of this embodiment is necessary. Figure 4 , Figure 4 The folded galvanic box at the top moves downwards as shown in the diagram, driven by the material-taking component 201, bringing the folded galvanic box closer to the material-stopping component 3. During this process... Figure 4 The dashed arrow in the middle becomes Figure 4 In the lower state, the stopper 3 enters the folded walnut box through the gaps 8 on the front and sides above, and then abuts against the back of the folded walnut box. (Refer to...) Figure 5As shown above, the stopper 3 remains stationary, blocking the back of the walnut box, while the take-up component 201 continuously moves the front of the walnut box downwards as shown in the figure, thereby achieving the pre-opening of the walnut box; after the pre-opening is completed, as shown... Figure 5 The dashed arrow indicates that it becomes Figure 5 In the lower position, the opening mechanism can more easily and completely open the walnut box. Therefore, this embodiment achieves pre-opening of the walnut box through the setting of the stop 3, allowing for stable opening even under high-speed operation. If pre-opening is not performed, then refer to... Figure 9 Under high-speed operation, the front and back of the valence box may not separate in time and remain pressed together. At this point, the side guide plate of the opening mechanism directly pushes the side of the valence box, causing it to bend as a whole. That is, the back of the valence box will not move away from the front but will instead bend and deform. This situation occurs more frequently with valence boxes that are relatively soft. Ultimately, as... Figure 9 The example shown depicts a situation where opening the box fails. However, in this embodiment, because the box was pre-opened, the front and back of the walnut box were separated beforehand, preventing the back from bending or deforming when the box was opened later.

[0030] Furthermore, refer to Figure 1 and Figure 4-5 The stopper 3 pre-opens the walnut box. During this pre-opening process, the back of the walnut box moves laterally, moving away from the front. To facilitate this lateral movement, a travel distance is provided between the stopper 3 and the outlet of the feeder 1. Specifically, the stopper 3 is positioned after extending a certain distance outward from the outlet of the feeder 1. This travel distance allows space for the back of the walnut box to move, ensuring smooth pre-opening even at high speeds. Throughout the pre-opening and subsequent opening processes, the stopper 3 remains inside the walnut box. It's important to note that this travel distance can be flexibly determined based on the size of the walnut box and the degree of pre-opening.

[0031] Furthermore, such as Figure 3 When there is no height difference between the folded portion 9 on the upper side of the walnut box and the folded portion on the upper front of the walnut box, the stop part 3 needs to be as follows: Figure 4 As shown, the material enters the interior of the valence box through the gap 8, therefore the baffle 3 is preferably configured as a thin rod structure, and if the valence box is in the form of... Figure 6 As shown, in this type of trough, the folded portion 9 on the upper side is lower than the folded portion on the upper front of the trough. Therefore, the baffle 3 can directly enter the trough from the height difference position, and it does not necessarily need to be a thin rod structure. Meanwhile, for... Figure 3For the valence box, the stop 3 needs to be raised, and then the valence box moves to the side for subsequent processing. Figure 6 With the Valen box, the baffle 3 does not need to rise and can move directly along... Figure 6 The direction indicated by the middle arrow is to move away from the side.

[0032] Furthermore, refer to Figure 1-2 This embodiment also includes a crossbeam 4, on which a slide rail 401 and a sliding block 402 that slides on the slide rail 401 and is locked are provided. An extension arm 403 is provided on the sliding block 402, and a stopper 3 is provided on the extension arm 403. The crossbeam 4, the slide rail 401, and the locking sliding block 402 enable the installation and lateral adjustment of the stopper 3. The locking structure can be a locking handle well-known in the art. The extension arm 403 is used to extend the stopper 3 outward a certain distance, so that in the above embodiment, the stopper 3 is positioned in the folded state where the walnut box is completely detached from the feeder 1. At the same time, the extension arm 403 is provided with several mounting positions 5, on which the stopper 3 is installed. Specifically, the mounting position 5 is a hole-like structure, and the stopper 3 is inserted into the hole and then fixed laterally by a set screw. Through the above structure, the lateral position and outward extension distance of the stopper 3 can be adjusted, better adapting to walnut boxes of different specifications.

[0033] Furthermore, refer to Figure 2-3 In response to Figure 3 In this type of walnut box, the stop 3 needs to be raised and lowered. Specifically, the extension arm 403 is equipped with a lifting mechanism 6, and the extension arm 403 is fixedly mounted on the lifting end of the lifting mechanism 6. The lifting mechanism 6 can be a cylinder, thereby realizing the raising and lowering of the stop 3.

[0034] Furthermore, the crossbeam 4 is positioned above or below the feeding rack 1. The crossbeam 4 is preferably positioned above to facilitate manual adjustment of the position of the stop 3. However, the crossbeam 4 can also be positioned below. The principle of positioning it below is the same as that of positioning it above, only the orientation is adjusted.

[0035] Furthermore, the guide rail 3 can be installed on either the left or right side. Its function is to adapt to different folding methods of the walnut box. In actual processing, the guide rail 3 can be selectively installed on one side. For details, please refer to [reference needed]. Figure 8 , Figure 8 In the middle, the upper folded state of the Valen box d is folded to the left, so the gap 8 is on the left. At this time, the stop 3 is installed on the left to stop the material. Figure 8In the lower folded state, the walnut box e is folded to the right, so the gap 8 is on the right side. At this time, the stopper 3 is installed on the right side to stop the material. Thus, the stopper 3, which can be flexibly installed and disassembled to adjust its position, can be adapted to walnut boxes with different folding methods. According to the position of the gap 8 of the walnut box, the stopper 3 can be installed on the corresponding side, making it more convenient to use.

[0036] Furthermore, refer to Figure 3 and Figure 6-7 The box-opening mechanism 2 includes side guide plates 202, which act on the sides of the folded box to open it. Specifically, the side guide plates 202 abut against the sides of the box, creating a perpendicular angle between the sides and the front, thus ensuring accurate opening. Preferably, a pair of side guide plates 202 are provided, clamping the box from both sides for better accurate opening. The pair of side guide plates 202 can move back and forth and move closer or further apart; see the specific structure for details. Figure 7 A pair of side guide plates 202 are clamped on both sides of the synchronous belt 10, thereby allowing the side guide plates 202 to move closer or further apart. Forward and backward movement is achieved through a rocker arm mechanism 11, which converts the rotation of the servo motor into reciprocating forward and backward movement. With this structure, the side guide plates 202 can move forward towards the waler box, then clamp the waler box together, thus opening it. After opening, the external conveying mechanism clamps the waler box, and the side guide plates move away and backward, allowing the waler box to be transported away by the external conveying mechanism. Then, the next waler box is opened, and this process is repeated continuously to achieve continuous opening of the waler box.

[0037] 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.
