Detailed implementation manner

[0027] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Embodiment 1:

[0028] Refer to the attached Figure 1 and the attached Figure 2 and the attached Figure 3 and the attached Figure 6 and the attached Figure 7 , a limiting mechanism for a corrugated cardboard binding machine, including a base 10, a tabletop 11 is fixedly arranged on the upper end surface of the base 10, two groups of guide rollers 15 are symmetrically arranged on one side of the tabletop 11 on the upper end surface and are arranged obliquely, two rotating guide plates 16 are rotatably arranged on the tabletop 11 on both sides of the guide rollers 15, two first support plates 12 are fixedly arranged on the tabletop 11 on both sides of the two rotating guide plates 16, a drive roller 14 is rotatably arranged above the rotating guide plates 16 on the first support plate 12, and a first drive motor 13 is fixedly arranged on one side of the first support plate 12, and the output end of the first drive motor 13 is connected to the drive roller 14.

[0029] The side of the tabletop 11 where the guide rollers 15 are arranged is the side for feeding the corrugated cardboard. In the actual production process, production personnel generally choose to use a belt conveyor to transport the corrugated cardboard to be bound into the binding mechanism. The belt conveyor is a prior art and does not involve the limiting mechanism, and this solution is not restricted. The corrugated cardboard transported for feeding is often not located exactly in the middle. However, considering that the subsequent limiting and binding process requires the corrugated cardboard to be located in the middle of the mechanism. At this time, the two groups of guide rollers 15 on the tabletop 11 can play a role in adjusting the position of the offset corrugated cardboard. The two groups of guide rollers 15 are symmetrically arranged and are inclined. When the offset corrugated cardboard is transported onto the guide rollers 15, it will be affected by the inclined frictional force, so that its position is automatically adjusted. Similarly, the rotating guide plates 16 on both sides of the guide rollers 15 can play an auxiliary adjustment role and further limit the corrugated cardboard. During the entire process of adjusting the position, the first drive motor 13 drives the drive roller 14 to rotate, playing a role in pushing the corrugated cardboard on the guide rollers 15 for feeding.

[0030] Further, refer to the attachedFigure 2 , attached Figure 5 and attached Figure 8 , on the side of the rotating guide plate 16 away from the rotation center, 4 slots 31 are symmetrically opened on the table 11. Third support plates 32 are fixedly arranged on both sides of the slots 31. A secondary feeding component is slidably arranged in each slot 31; the secondary feeding component includes an electric push rod 17 fixedly arranged on the third support plate 32. The output end of the electric push rod 17 is connected with a connecting block 18. A second driving motor 21 is fixedly arranged on the connecting block 18. The output end of the second driving motor 21 is connected with a first feeding roller 19. A second feeding roller 20 is also rotatably arranged on the connecting block 18 below the first feeding roller 19.

[0031] The four slots 31 can be divided into two groups. One group of secondary feeding components on the side close to the guide roller 15 is responsible for feeding, and the other group of secondary feeding components on the side away from the guide roller 15 is responsible for discharging; the electric push rod 17 on the third support plate 32 can push the secondary feeding component to slide in the slot 31 to adapt to the limiting and feeding of corrugated cardboard boxes of different sizes. After the position of the corrugated cardboard box is adjusted on the guide roller 15, the driving roller 14 can continue to push the corrugated cardboard box forward until the corrugated cardboard box is pushed into one group of secondary feeding components on the side close to the guide roller 15. The second driving motor 21 in the secondary feeding component drives the first feeding roller 19 to rotate. With the cooperation of the second feeding roller 20, the first feeding roller 19 can continue to push the corrugated cardboard box forward.

[0032] Further, referring to attached Figure 2 and attached Figure 3 , a connecting rod 22 is rotatably arranged on the side of the rotating guide plate 16 away from the rotation center. The other end of the connecting rod 22 is connected to the connecting block 18 in the adjacent secondary feeding component. The production personnel can adjust the distance between the two secondary feeding components by controlling the extending position of the electric push rod 17. The setting of the connecting rod 22 enables the production personnel to adjust the angle of the rotating guide plate 16 by the way while adjusting the distance between the two rollers to adapt to corrugated cardboard boxes of different sizes, and assist in adjusting and controlling the position of the corrugated cardboard box to further limit its position.

[0033] Further, referring to attached Figure 1 , attached Figure 4 and attached Figure 8, a binding component is fixedly arranged between the two groups of secondary feeding components, and the binding component will be specifically described in Embodiment II. When the corrugated cardboard box is pushed into the binding component by a group of secondary feeding components close to the side of the guide roller 15, and after the binding process is completed, the secondary feeding component for feeding will continue to push the corrugated cardboard box, and the corrugated cardboard box will be pushed into a group of secondary feeding components on the side away from the guide roller 15. The group of corrugated cardboard boxes on the side away from the guide roller 15 functions as discharging. The second driving motor 21 in the secondary feeding component continuously drives the first feeding roller 19 to rotate, and with the cooperation of the second feeding roller 20, the discharged corrugated cardboard box after binding can be operated.

[0034] Specifically, initially, the production personnel can adjust the positions of the two groups of secondary feeding components according to the size of the corrugated cardboard box to be processed. In each group of secondary feeding components, the distance between two secondary feeding components should be adapted to the size of the corrugated cardboard box, which can not only play the function of feeding or discharging, but also play a role in limiting its position. A connecting rod 22 is connected between the secondary feeding component close to the side of the guide roller 15 and the rotating guide plate 16. When the production personnel adjust the position of the secondary feeding component, the angle of the rotating guide plate 16 will also be adjusted and changed.

[0035] During the production process, the belt conveyor transports the corrugated cardboard box to be bound into this mechanism. The corrugated cardboard box first enters the side of the guide roller 15 and adjusts its own position through the guide roller 15; during the adjustment process, the first driving motor 13 drives the driving roller 14 to continuously rotate and continue to push the corrugated cardboard box forward; the setting of the guide roller 15 enables the corrugated cardboard box to be located in the center of the overall mechanism after adjustment, so that the corrugated cardboard box can smoothly enter a group of secondary feeding components close to the side of the guide roller 15.

[0036] Subsequently, a group of secondary feeding components close to the side of the guide roller 15 push the corrugated cardboard box into the binding component, and the binding component performs a binding process on it; after the binding is completed, a group of secondary feeding components close to the side of the guide roller 15 push the corrugated cardboard box forward continuously so that the corrugated cardboard box enters a group of secondary feeding components on the side away from the guide roller 15. The group of corrugated cardboard boxes on the side away from the guide roller 15 functions as discharging, transports the processed corrugated cardboard box out of this mechanism, and waits for the next corrugated cardboard box to be processed to enter this mechanism. Embodiment II:

[0037] Refer to Appendix Figure 4 Appendix Figure 5 And Appendix Figure 8, the binding assembly includes a mounting frame 23 fixedly arranged on the upper end surface of the table 11. Two second support plates 25 are fixedly arranged on the mounting frame 23. A third driving motor 26 is fixedly arranged on one of the second support plates 25. A lead screw 27 is rotatably arranged between the two second support plates 25. The output end of the third driving motor 26 is connected to the lead screw 27. A slider 28 is slidably arranged on the second support plate 25. A chute 24 is also arranged on the mounting frame 23. The slider 28 passes through the chute 24 and extends to the lower end of the mounting frame 23. A pressing roller 29 is rotatably arranged on the slider 28 below the mounting frame 23. A binding head 30 is fixedly arranged on the slider 28 on one side of the pressing roller 29.

[0038] As a further embodiment, during binding, the corrugated cardboard box has been loaded in place. The third driving motor 26 can drive the lead screw 27 to rotate and make the slider 28 thereon move forward. In this relationship, the pressing roller 29 on the slider 28 will flatten the part of the corrugated cardboard box to be bound before the binding head 30 binds the corrugated cardboard box, assisting the binding head 30 to bind the corrugated cardboard box and improving the final binding effect. The binding head 30 is a prior art, and this solution will not be elaborated too much.

[0039] After binding is completed, the corrugated cardboard box continues to move forward to complete unloading. At this time, the production personnel can control the third driving motor 26 to drive the lead screw 27 to reverse. Under the screw thread fit, the slider 28 on the lead screw 27 retreats in the reverse direction and returns to the initial position, waiting for the next corrugated cardboard box to be processed to enter this mechanism.
