DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application embodiment discloses a cardboard conveying device. Figure 1 and Figure 2The cardboard conveying device includes a frame 1, on which a conveyor belt 2 is arranged, and the conveying direction of the conveyor belt 2 is the length direction of the frame 1, and the conveyor belt 2 is used to convey the cardboard folded by the previous process. The frame 1 is also provided with a positioning mechanism 3, and the positioning mechanism 3 includes a positioning frame 31 and a driving component 32. The positioning frame 31 is slidably connected to the frame 1, and the cardboard on the conveyor belt 2 is located on the sliding path of the positioning frame 31. The driving component 32 is used to drive the positioning frame 31 to slide a certain distance.

[0032] Reference Figure 1 and Figure 2 , the number of conveyor belts 2 on the frame 1 is set to be several, and they are arranged along the width direction of the frame 1. Optionally, in the embodiment of the present application, the number of conveyor belts 2 is set to be two, and the two conveyor belts 2 share a driving source. The frame 1 is also provided with guide rods 4, and the guide rods 4 are set to be two, and are respectively located on both sides of the frame 1 along its own width direction, and the two guide rods 4 are located above the conveyor belt 2. Each guide rod 4 extends along the length direction of the frame 1, and both ends of each guide rod 4 are fixedly connected to the frame 1 by bolts.

[0033] Reference Figure 1 and Figure 2 The frame 1 is also provided with an adjustment mechanism 5, which includes an adjustment frame 51 and an adjustment assembly 52. ​​Each guide rod 4 passes through the adjustment frame 51 and is slidably connected to the adjustment frame 51. The adjustment frame 51 is slidably connected to the frame 1 through the guide rod 4. A pressing frame 6 is also provided at the end of the bottom of the adjustment frame 51 away from the positioning frame 31. The top of the pressing frame 6 is fixedly connected to the adjustment frame 51 by welding. The bottom end of the pressing frame 6 extends downward and is inclined toward the end close to the positioning frame 31. The bottom end of the pressing frame 6 contacts the top wall of the cardboard on the conveyor belt 2, thereby pressing the cardboard.

[0034] Reference Figure 1 and Figure 2 The adjusting assembly 52 includes an adjusting screw rod 521 and an adjusting member 522. The adjusting screw rod 521 is arranged parallel to the guide rod 4. Both ends of the adjusting screw rod 521 are rotatably connected to the frame 1 through bearings. The adjusting screw rod 521 is located above the guide rod 4. One end of the adjusting screw rod 521 passes through the adjusting frame 51 and is threadedly connected to the adjusting frame 51.

[0035] Reference Figure 1 and Figure 2 Optionally, in the embodiment of the present application, the adjusting member 522 is a servo motor, the output shaft of the servo motor is fixedly connected to one end of the adjusting screw rod 521 through a coupling, and the servo motor is fixedly mounted on the frame 1. The servo motor is provided with a brake device for locking the output shaft of the servo motor when the servo motor stops working. The brake device is a prior art, so it is not described here.

[0036] Reference Figure 1 and Figure 2 Each guide rod 4 passes through the positioning frame 31 and is slidably connected to the positioning frame 31. The positioning frame 31 is slidably connected to the frame 1 through the guide rod 4. An extension portion 311 is further extended downward from the end of the positioning frame 31 away from the pressing frame 6. The extension portion 311 is higher than the top of the cardboard on the conveyor belt 2. A pushing frame 33 is also provided on the extension portion 311. The top end of the pushing frame 33 is rotatably connected to the bottom end of the extension portion 311 through a pin shaft. A side wall of the pushing frame 33 close to the adjustment frame 51 abuts against the extension portion 311, thereby ensuring the effect of the pushing frame 33 pushing the cardboard. The pushing frame 33 is located between the two conveyor belts 2 and extends to below the top end of the conveyor belt 2.

[0037] Reference Figure 1 and Figure 2 In the initial state, the extension part 311 is kept vertically downward, and the bottom end of the extension part 311 is lower than the top end of the cardboard on the conveyor belt 2. When the conveyor belt 2 transports the cardboard from one end thereof to the end where the positioning frame 31 is located, the cardboard gradually moves from the side of the positioning frame 31 close to the adjustment frame 51 to the side of the positioning frame 31 away from the adjustment frame 51.

[0038] Reference Figure 1 and Figure 2 In this process, the pressing frame 6 first presses the cardboard to ensure the folding effect of the cardboard, and then the cardboard abuts against the pushing frame 33, so that the pushing frame 33 rotates away from the adjusting frame 51 and contacts with the top of the cardboard, so that the cardboard passes smoothly. When the cardboard is completely moved to the side of the pushing frame 33 away from the adjusting frame 51, the pushing frame 33 rotates downward under its own gravity and continues to abut against the extension portion 311.

[0039] Reference Figure 1 and Figure 2 The driving assembly 32 includes a driving member 321, an active frame 322 and a driven frame 323. Optionally, in the embodiment of the present application, the driving member 321 is a servo motor, which is fixedly mounted on the adjustment frame 51 by bolts, and the axial direction of the output shaft of the servo motor is the width direction of the frame 1. The servo motor is provided with a brake device to lock the output shaft of the servo motor when the servo motor stops working. The brake device is a prior art, so it will not be described here.

[0040] Reference Figure 1 and Figure 2One end of the active frame 322 is fixedly sleeved on the output shaft of the servo motor, the other end of the active frame 322 is rotatably connected to one end of the driven frame 323 through a pin, and the other end of the driven frame 323 is rotatably connected to the top of the positioning frame 31 through a pin. The length of the active frame 322 is shorter than that of the driven frame 323, and a crank rocker mechanism is formed between the active frame 322, the driven frame 323 and the positioning frame 31.

[0041] Reference Figure 1 and Figure 2 Optionally, in order to further enhance the positioning effect of the cardboard, relevant personnel can enable the pushing frame 33 to push the cardboard until it abuts against the internal components of the sealing device on one end of the frame 1, thereby further enhancing the positioning effect of the cardboard.

[0042] Reference Figure 1 and Figure 2 , when the cardboard is completely displaced to the side of the push frame 33 away from the adjustment frame 51, at this time, the push frame 33 returns to the vertical state under the action of its own gravity, and continues to abut against the extension part 311. At this time, the output shaft of the driving member 321 rotates, driving the active frame 322 to rotate, so that the active frame 322 drives the driven frame 323 to swing, so that the positioning frame 31 slides back and forth along the conveying direction of the conveyor belt 2. In this process, the positioning frame 31 drives the push frame 33 to contact the end of the cardboard, and pushes the cardboard to slide a specified distance, and finally abuts against the internal components of the sealing device to achieve positioning. After the pushing is completed, the positioning frame 31 returns to the initial position, which is convenient for positioning the next cardboard.

[0043] The implementation principle of a cardboard conveying device in the embodiment of the present application is as follows: when in use, the conveyor belt 2 transports the cardboard to a position close to the sealing device. In this process, the pressing frame 6 first presses the cardboard to ensure the folding effect of the cardboard, and then the cardboard abuts against the pushing frame 33, so that the pushing frame 33 rotates in a direction away from the adjusting frame 51 and contacts with the top of the cardboard, so that the cardboard passes smoothly. When the cardboard is completely displaced to the side of the pushing frame 33 away from the adjusting frame 51, the pushing frame 33 rotates downward under the action of its own gravity and continues to abut against the extension portion 311.

[0044] At this time, the output shaft of the driving member 321 rotates, and through the active frame 322 and the driven frame 323, the positioning frame 31 slides back and forth along the conveying direction of the conveyor belt 2. In this process, the positioning frame 31 drives the pushing frame 33 to contact the end of the cardboard, and pushes the cardboard to slide a specified distance, and finally abuts against the internal components of the sealing device to achieve positioning. After the pushing is completed, the positioning frame 31 returns to the initial position, which is convenient for positioning the next cardboard.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
