[0023] like Figure 1As shown, the carton conveying device includes two left and right synchronous conveying units 1, and a spacing for accommodating cartons A is formed between the left and right synchronous conveying units 1. In addition, a supporting bottom plate 2 is provided between the left and right synchronous conveying units 1. Each synchronous conveying unit 1 includes a conveyor belt mechanism 10, such as Figure 2 As shown, the conveyor belt mechanism 10 includes a conveyor belt 100, and a plurality of box pushing blocks 101 are equally divided on the conveyor belt 100 along the belt length direction.

[0024] The conveying principle is as follows: Figure 1 As shown, when carton A enters between the left and right synchronous conveying units 1, the supporting bottom plate 2 supports carton A from the bottom, and the conveyor belts 100 of the left and right synchronous conveying units 1 rotate synchronously, and the box-pushing block 101 on the conveyor belt 100 pushes the carton forward from the back of carton A. This conveying method has a reasonable structure, the box-pushing block 101 can give stable thrust to carton A, and the equipment control system can know the position of the carton by calculating the position of the box-pushing block 101 (calculated by the servo motor encoder), so that the closing mechanism for closing the carton can be controlled to move accurately without the need for sensors (the four side covers A1 above the carton and the four side covers below the carton must be closed), thereby greatly simplifying the equipment structure and reducing the manufacturing cost. Even if the carton specifications change, there is no need to adjust the sensor position (for existing sensors, when the carton specifications change, the sensor position must be adjusted).

[0025] In order to adapt to the transportation of cartons A with different widths, Figure 4 As shown, one of the synchronous conveying units 1 is arranged on a transverse sliding seat 3, and the transverse sliding seat 3 is slidably arranged on a transverse guide rail 4 arranged transversely. By moving the transverse sliding seat 3, the transverse sliding seat 3 can carry one of the synchronous conveying units 1 to move transversely, such as Figure 5 As shown, the spacing between the two synchronous conveying units 1 can be adjusted to accommodate cartons of different widths. It should be noted that the transverse sliding seat 3 can be moved manually and then fixed by pins or other methods.

[0026] To facilitate adjustment, Figure 4 As shown, a first transverse screw rod 5 is provided on one side of the transverse guide rail 4, and a first nut 50 is connected to the first transverse screw rod 5, and the first nut 50 is connected to the transverse sliding seat 3. By rotating the first transverse screw rod 5, the first nut 50 moves together with the transverse sliding seat 3, and the transverse sliding seat 3 can carry one of the synchronous conveying units 1 to move transversely, so that the spacing between the two synchronous conveying units 1 can be adjusted to accommodate cartons of different widths. It should be noted here that the first transverse screw rod 5 can be rotated and adjusted manually.

[0027] like Figure 3 and Figure 8 As shown, the tape sealing mechanism 8 is a device for sealing the tape 80 on the carton A. Since the gap formed after the left and right sides of the carton A are covered on A1 is in the middle position, the tape sealing mechanism 8 must be in the middle position of the two synchronous conveying units 1. Therefore, when the spacing between the two synchronous conveying units 1 changes, the position of the tape sealing mechanism 8 must also change accordingly. To this end, a second transverse screw 7 parallel to the first transverse screw 5 is provided on one side of the first transverse screw 5, and a second nut 70 is connected to the second transverse screw 7, and the second nut 70 is connected to the movement slide 6 for installing the tape sealing mechanism 8, and the movement slide 6 is slidably set on the transverse guide rail 4. By moving the movement slide 6, the movement slide 6 can carry the tape sealing mechanism 8 to move, so that the tape sealing mechanism 8 can be adjusted to the middle position of the two synchronous conveying units 1. It should be noted here that the second transverse screw 7 can be adjusted by manual rotation.

[0028] As mentioned above, the position adjustment of the synchronous conveying unit 1 and the position adjustment of the tape sealing mechanism 8 are both manually adjusted, and both need to be adjusted separately, which is very inconvenient. In order to achieve automatic adjustment and simplify the adjustment method, Figure 4 As shown, in the present invention, a first transmission wheel 51 (which may be a synchronous wheel or a sprocket wheel) is connected to the first transverse screw rod 5, and a second transmission wheel 71 (of the same type as the first transmission wheel) is connected to the second transverse screw rod 7. Figure 3 As shown, a lateral adjustment transmission belt 20 (which may be a synchronous belt or a chain, depending on the type of transmission wheel) is wound around the first transmission wheel 51 and the second transmission wheel 71, and the lateral adjustment transmission belt 20 is transmission-connected to the lateral adjustment power source 200, and the pitch of the first lateral screw 5 is twice as large as the pitch of the second lateral screw 7 or the number of teeth of the first transmission wheel 51 is twice as large as the number of teeth of the second transmission wheel 71. During adjustment, the lateral adjustment power source 200 drives the lateral adjustment transmission belt 20 to rotate, and the lateral adjustment transmission belt 20 drives the first transmission wheel 51 and the second transmission wheel 52 to rotate at the same time, so that the first lateral screw 5 and the second lateral screw 7 rotate at the same time. Since the pitch of the first lateral screw 5 is twice as large as the pitch of the second lateral screw 7 or the number of teeth of the first transmission wheel 51 is twice as large as the number of teeth of the second transmission wheel 71, the moving distance of the first nut 50 on the first lateral screw 5 is twice as large as the moving distance of the second nut 70 on the second lateral screw 7, that is, the moving distance of the synchronous conveying unit 1 is twice as large as the moving distance of the tape sealing mechanism 8. In this way, the tape sealing mechanism 8 and one of the synchronous conveying units 1 can achieve synchronous adjustment, and the tape sealing mechanism 8 is always in the middle position between the two synchronous conveying units 1, ensuring that the tape sealing mechanism 8 can seal the tape 80 in the middle position of the carton A.

[0029] The supporting bottom plate 2 is located at the bottom, supporting the carton A. Figure 5 As shown, when the spacing between the two synchronous conveying units 1 changes, the position of the support base plate 2 also needs to change accordingly. For this reason, the present invention connects the support base plate 2 to the movement slide 6. As described above, when adjusting, the tape sealing movement 8 is always in the middle position between the two synchronous conveying units 1, and the tape sealing movement 8 and the support base plate 2 are both connected to the movement slide 6, so the support base plate 2 is also always in the middle position between the two synchronous conveying units 1. Of course, as long as the support surface of the support base plate 2 is wider, or the adjustment distance between the two synchronous conveying units 1 is smaller, the support base plate 2 can also be adjusted without moving.

[0030] The heights of cartons are different. In order to meet the transportation needs of cartons of different heights, Figure 1 As described above, the synchronous conveying unit 1 of the present invention includes two upper and lower conveyor belt mechanisms 10 (so that the left and right synchronous conveying units 1 have four conveyor belt mechanisms 10, and the four conveyor belt mechanisms 10 have four box pushing blocks 101 to push the carton when conveying the carton, so that the pushing can be more stable), such as Figure 3 and Figure 6 As shown, the conveyor belt mechanism 10 of the synchronous conveying unit 1 located at the top is installed on the lifting seat 11, and the lifting seat 11 is installed on the support body 12 in a lifting and adjusting manner. The conveyor belt mechanism 10 of the synchronous conveying unit 1 located at the bottom is installed on the support body 12, and the support body 12 is installed on the transverse sliding seat 3. When the transverse sliding seat 3 moves transversely, the transverse sliding seat 3 carries the support body 12 to move together. Since the upper and lower conveyor belt mechanisms 10 of the synchronous conveying unit 1 are both installed on the support body 12, the synchronous conveying unit 1 also moves transversely, which realizes the adjustment of the distance between the two synchronous conveying units 1 mentioned above, so as to adapt to the transportation of cartons of different widths; in order to adapt to the transportation of cartons of different heights, as shown in FIG. Figure 7 As shown, as long as the lifting seat 11 is lifted up and down, the conveyor belt mechanism 10 installed on the lifting seat 11 is also lifted up and down (the height of the conveyor belt mechanism 10 installed on the supporting body 12 remains unchanged), thereby meeting the transportation of cartons of different heights. It should be noted here that the lifting seat 11 can be lifted up and down manually and then fixed with pins.

[0031] For the convenience of adjustment, a lifting adjustment screw 13 is rotatably provided in the support body 12, and a lifting nut 14 is connected to the lifting adjustment screw 13, and the lifting nut 14 is connected to the lifting seat 11. When adjusting, as long as the lifting adjustment screw 13 is rotated, the lifting nut 14 on the lifting adjustment screw 13 will lift the lifting seat 11 up and down. It should be noted here that the lifting adjustment screw 11 can be rotated and adjusted manually.

[0032] In order to facilitate the rotation of the lifting adjustment screw 13, while ensuring that the support body 12 moves horizontally with the horizontal sliding seat 3, as shown in FIG. Figure 6 As shown, the present invention connects the lifting and adjusting screw 13 to the spline shaft 18 in a transmission manner, the lifting and adjusting screw 13 is connected to the first bevel gear 15, the spline shaft 18 is connected to the second bevel gear 16, the first bevel gear 15 is meshed with the second bevel gear 16, the second bevel gear 16 is connected to the spline sleeve 17, and the spline sleeve 17 is sleeved on the spline shaft 18, and the spline sleeve 17 is rotatably mounted on the support body 12. Through this structure, as long as the spline shaft 18 is rotated, the spline shaft 18 drives the spline sleeve 17 to rotate, the spline sleeve 17 drives the second bevel gear 16 to rotate, the second bevel gear 16 drives the first bevel gear 15 to rotate, and finally the first bevel gear 15 drives the lifting and adjusting screw 13 to rotate. When the synchronous conveying unit 1 is to achieve lateral movement, the spline sleeve 17 realizes axial movement on the spline shaft 18, thereby carrying the support body 12 to move lateral together. It should be noted here that the spline shaft 18 can be rotated and adjusted manually. The left and right synchronous conveying units 1 are connected to the spline shaft 18 through the same structure. By rotating the spline shaft 18, the left and right synchronous conveying units 1 can be adjusted synchronously to change the height of the conveyor belt mechanism 10 above the synchronous conveying units 1.

[0033] Finally, it is worth mentioning that in order to achieve automatic adjustment, the present invention is connected to the spline shaft 18 with a third transmission wheel 19 (which can be a synchronous wheel or a sprocket), and the third transmission wheel 19 is wound with a lifting and adjusting transmission belt 21 (which can be a synchronous belt or a chain), and the lifting and adjusting transmission belt 21 is connected to the lifting and adjusting power source. Driven by the lifting and adjusting power source, the lifting and adjusting transmission belt drives the third transmission wheel 210 to rotate, and the third transmission wheel 210 drives the spline shaft 18 to rotate. Through this structure, the height of the conveyor belt mechanism 10 located above the synchronous conveying unit 1 can be automatically adjusted to adapt to the transportation of cartons of different heights.
