Description

Technical Field

[0001] This utility model relates to the technical field of limiting mechanisms for corrugated carton binding machines, specifically a limiting mechanism for corrugated carton binding machines. Background Technology

[0002] Corrugated cardboard boxes are a common type of packaging container with many advantages. They are widely used in logistics, retail, and other fields. Before use, corrugated cardboard boxes need to be bound together using a binding machine to give the box a fixed shape and structure, enabling it to withstand certain pressure and weight, protect the contents, and ensure good integrity and packaging effect. When binding corrugated cardboard boxes, operators need to hold the box by hand to keep it in a stable position and ensure that the binding staples are accurately driven into the predetermined positions to guarantee binding quality.

[0003] When corrugated cardboard boxes are secured manually, workers' hands are easily injured or pinched by the staples. Manually supporting the boxes makes it difficult to guarantee accurate positioning every time, especially when the boxes are large or irregularly shaped. Operators may not be able to accurately control the position of the boxes, leading to deviations in the position of the staples, which affects the appearance and structural strength of the boxes. During the binding process, the operator's hands may shake involuntarily, or fatigue from holding the boxes for a long time may cause unstable hand strength, which can cause the boxes to wobble, resulting in uneven staple arrangement, or even missing or overlapping staples, thus reducing the binding quality. Utility Model Content

[0004] The purpose of this utility model is to provide a limiting mechanism for a corrugated carton binding machine, in order to solve the problems mentioned in the background art where manual hand-holding is used to fix and limit corrugated cartons. This method is problematic because workers' hands are easily injured or pinched by the binding staples, and manual support makes it difficult to ensure accurate positioning each time. Especially when the carton is large or irregularly shaped, operators may not be able to accurately control its position, leading to deviations in the binding staples' placement, affecting the carton's appearance and structural strength. During the binding process, the operator's hands may involuntarily tremble, or fatigue from prolonged support may cause unstable hand strength, resulting in the carton shaking, uneven binding staple arrangement, and even problems such as missing or overlapping staples, thus reducing binding quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting mechanism for a corrugated carton binding machine, comprising a supporting base plate, wherein first fixed vertical plates are symmetrically fixedly connected to both sides of the top of the supporting base plate, a first bidirectional lead screw is rotatably connected to the middle of the two first fixed vertical plates, two movable horizontal plates are symmetrically threaded to the middle of the first bidirectional lead screw, a sliding clamping assembly is fixedly connected to the top of the two movable horizontal plates, and two first support rods are symmetrically passed through the middle of the two movable horizontal plates, with the two ends of the two first support rods respectively fixedly connected to the inner sides of the two first fixed vertical plates. A driving component is fixedly connected to the middle of the supporting base plate, and a transmission component is driven to the middle of the driving component. A support component is fixedly connected to the top center of the supporting base plate. This device can adjust the clamping blocks to move in different directions, thereby clamping and fixing the corners of the corrugated cardboard box, making the corrugated cardboard box stable and helping to ensure the stability and quality of the box binding. By clamping and fixing the corrugated cardboard box with the clamping blocks, manual intervention steps are reduced, the safety of the binding process is improved, and the mechanical replacement of manual labor in the box binding reduces the intensity of manual labor and improves work efficiency.

[0006] Preferably, each of the four corners of the bottom of the supporting base plate is fixedly connected to a support leg, and the bottom of the support leg is provided with a through mounting hole, so as to facilitate the fixed installation of the device on the worktable of the binding machine and to facilitate its use in conjunction with the binding machine.

[0007] Preferably, the sliding clamping assembly includes two limiting slide rails, which are respectively fixedly connected to the top center of two movable horizontal plates. Two sliding plates are symmetrically slidably connected inside each of the two limiting slide rails. A clamping block is fixedly connected to the top of the two sliding plates inside the same limiting slide rail at their close ends, so that the clamping blocks can move closer or further apart in one direction, which is convenient for clamping and fixing cartons of different sizes.

[0008] Preferably, each sliding plate has a connecting frame fixedly connected to its bottom end, a connecting shaft fixedly connected to the middle of the outer side of the connecting frame, and an anti-detachment block fixedly connected to the end of the connecting shaft away from the connecting frame, making the connection structure more stable.

[0009] Preferably, the driving assembly includes two second fixed vertical plates, which are symmetrically fixedly connected to the top center of the supporting base plate. A second bidirectional lead screw is rotatably connected between the two second fixed vertical plates, with one end of the second bidirectional lead screw passing through one of the second fixed vertical plates. Two second support rods are symmetrically fixedly connected between the two second fixed vertical plates, and the second support rods are symmetrically distributed on both sides of the second fixed vertical plates. A drive motor is fixedly installed on one side of both the second and first fixed vertical plates. The output shafts of the two drive motors are respectively connected to the ends of the second bidirectional lead screw and the first bidirectional lead screw, so that the clamping block can slide in different directions, facilitating contact with the corners of cartons of different sizes and expanding the applicability of the limiting mechanism.

[0010] Preferably, the transmission assembly includes two drive plates, which are symmetrically threaded to the middle of the second bidirectional lead screw. The two drive plates are penetrated by two second support rods. A transmission frame is fixedly connected to the top of each of the two drive plates. A through straight slot hole is opened in the middle of the transmission frame. The transmission frame is movably sleeved on the outside of the connecting shaft, so that the sliding block can run simultaneously in different directions, which facilitates quick clamping and fixing of corrugated boxes and improves processing efficiency.

[0011] Preferably, the support assembly includes four fixed columns, which are symmetrically fixedly connected to the top center of the bearing base plate. A placement platform is fixedly connected to the top of the four fixed columns to support the corrugated cardboard box, so that the corrugated cardboard box and the clamping block are on the same plane, reducing the labor intensity of placing the cardboard box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By designing a first fixed vertical plate, a drive motor, a first bidirectional lead screw, a moving horizontal plate, a limit slide rail, a sliding plate, a clamping block, a connecting frame, a first support rod, an anti-detachment block, a transmission frame, a straight slot through hole, a drive plate, a second fixed vertical plate, a second bidirectional lead screw, and a second support rod, the clamping block can slide in different directions when the two drive motors are running. It can precisely control the movement of the clamping block in two directions according to different binding requirements, and adapt to the clamping and positioning requirements of various cartons of different shapes and sizes.

[0014] By replacing manual labor with the aforementioned mechanical structure to limit and fix the cardboard box, precise positioning and fixation of the cardboard box can be achieved, ensuring the accurate placement of the binding staples. This avoids binding quality problems caused by positioning deviations during manual clamping. Furthermore, the device can maintain a stable clamping force during the binding process, unlike manual labor which may result in hand tremors or unstable force due to fatigue or emotional factors. This effectively prevents the cardboard box from shaking during binding, ensures the even distribution and neat arrangement of the binding staples, and improves the structural strength and stability of the cardboard box.

[0020] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-4 This utility model provides a limiting mechanism for a corrugated cardboard box binding machine, including a supporting base plate 1. First fixed vertical plates 4 are symmetrically fixedly connected to both sides of the top of the supporting base plate 1. A controller is fixedly installed on the side of each of the first fixed vertical plates 4 to control the forward and reverse rotation and the number of rotations of two drive motors 5. A first bidirectional lead screw 6 is rotatably connected to the middle of the two first fixed vertical plates 4. Two movable horizontal plates 7 are symmetrically threaded to the middle of the first bidirectional lead screw 6. The two movable horizontal plates 7 move in opposite directions. Sliding clamping assemblies are fixedly connected to the top of the two movable horizontal plates 7. Two first support rods 12 are symmetrically inserted through the middle of the two movable horizontal plates 7. The two ends of the two first support rods 12 are respectively fixedly connected to the inner sides of the two first fixed vertical plates 4. When the drive motor 5 located on the side of the first fixed vertical plate 4 runs, it drives the first bidirectional lead screw 6 to rotate. The rotation of the first bidirectional lead screw 6 and the two movable horizontal plates 7 are screwed together, so that the two movable horizontal plates 7 move closer or further away from each other along the first support rods 12. A drive assembly is fixedly connected to the middle of the bearing base plate 1. A transmission assembly is connected to the middle of the drive assembly. A support assembly is fixedly connected to the middle of the top of the bearing base plate 1.

[0022] Furthermore, support legs 2 are fixedly connected to the four corners of the bottom of the support base plate 1. The support legs 2 have through mounting holes 3 in the middle of their bottom ends. Before using the device, use fixing bolts to pass through the mounting holes 3 to fix the support legs 2 to a suitable position on the worktable of the binding machine.

[0023] Furthermore, the sliding clamping assembly includes two limiting slide rails 8, which are fixedly connected to the top center of the two moving horizontal plates 7 respectively. Two sliding plates 9 are symmetrically slidably connected inside each of the two limiting slide rails 8. A clamping block 10 is fixedly connected to the top of the two sliding plates 9 inside the same limiting slide rail 8 at their closest points. A pressure sensor is fixedly installed on the inner wall of each clamping block 10. The pressure sensor is used to detect the pressure between the clamping block 10 and the carton. When the pressure reaches a predetermined threshold, the corresponding drive motor 5 stops running under the control of the controller. When the two moving horizontal plates 7 move closer or further away from each other along the first support rod 12, they drive the limiting slide rails 8, sliding plates 9 and clamping blocks 10 to move accordingly.

[0024] Furthermore, each of the sliding plates 9 is fixedly connected to a connecting frame 11 at its bottom end. A connecting shaft 22 is fixedly connected to the middle of the outer side of the connecting frame 11. An anti-detachment block 13 is fixedly connected to the end of the connecting shaft 22 away from the connecting frame 11. The anti-detachment block 13 is designed to cooperate with the transmission frame 14 so that the transmission frame 14 provides driving force to the connecting frame 11. When the two moving horizontal plates 7 move closer or further away from each other along the first support rod 12, the limiting slide rail 8, the sliding plate 9 and the clamping block 10 move together. The connecting frame 11 moves together with them. At this time, the connecting shaft 22 slides inside the straight groove through hole 15.

[0025] Furthermore, the drive assembly includes two second fixed vertical plates 17, which are symmetrically fixedly connected to the top center of the supporting base plate 1. A second bidirectional lead screw 18 is rotatably connected between the two second fixed vertical plates 17, with one end of the second bidirectional lead screw 18 passing through one of the second fixed vertical plates 17. Two second support rods 19 are symmetrically fixedly connected between the two second fixed vertical plates 17, and the second support rods 19 are symmetrically distributed on both sides of the second fixed vertical plates 17. A drive motor 5 is fixedly installed on one side of both the second fixed vertical plate 17 and the first fixed vertical plate 4. The output shafts of the two drive motors 5 are respectively connected to the ends of the second bidirectional lead screw 18 and the first bidirectional lead screw 6. When the drive motor 5 located on the side of the second fixed vertical plate 17 is running, it drives the second bidirectional lead screw 18 to rotate. The rotation of the second bidirectional lead screw 18 engages with the drive plate 16, causing the two drive plates 16 to slide along the second support rods 19. During this process, the two drive plates 16 move away from or closer to each other.

[0026] Furthermore, the transmission assembly includes two drive plates 16, which are symmetrically threaded to the middle of the second bidirectional lead screw 18. The two drive plates 16 are penetrated by two second support rods 19. A transmission frame 14 is fixedly connected to the top of each of the two drive plates 16. A through straight slot hole 15 is opened in the middle of the transmission frame 14. The transmission frame 14 is movably sleeved on the outside of the connecting shaft 22. When the drive plates 16 move away from or closer to each other, they drive the connecting shaft 22, the connecting frame 11 and the sliding plate 9 to move. During this process, the sliding plate 9 slides in the limiting guide rail 8, and the clamping block 10 moves with the sliding plate 9 to clamp the outer corner of the carton.

[0027] Furthermore, the support assembly includes four fixed columns 20, which are symmetrically fixedly connected to the top center of the bearing base plate 1. The top of the four fixed columns 20 is fixedly connected to a placement platform 21. Before clamping the corrugated carton, the carton is first assembled along the fold line to make it rectangular, and then the folded carton is placed on the placement platform 21.

[0028] When this application embodiment is used:

[0029] Before binding the cartons, assemble them along the fold lines to form a rectangle. Then, place the folded cartons on the placement platform 21. The controller operates the drive motor 5 located on the side of the first fixed vertical plate 4, causing the first bidirectional lead screw 6 to rotate. The rotation of the first bidirectional lead screw 6 engages with the two moving horizontal plates 7, causing the two moving horizontal plates 7 to move closer or further apart along the first support rod 12. This causes the limiting slide rail 8, sliding plate 9, and clamping block 10 to move accordingly. The connecting frame 11 moves simultaneously with it. At this time, the connecting shaft 22 slides inside the straight slot through hole 15, located on the side of the second fixed vertical plate 17. When the drive motor 5 is running, it drives the second bidirectional lead screw 18 to rotate. The rotation of the second bidirectional lead screw 18 engages with the drive plate 16, causing the two drive plates 16 to slide along the second support rod 19. During this process, the two drive plates 16 move away from or closer to each other, driving the connecting shaft 22, the connecting frame 11, and the sliding plate 9 to move. During this process, the sliding plate 9 slides within the limit guide rail 8, and the clamping block 10 moves with the sliding plate 9 to clamp the outer corner of the carton. The pressure sensor detects the pressure between the clamping block 10 and the carton. When the pressure reaches a predetermined threshold, the corresponding drive motor 5 stops running under the control of the controller.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
