[0022] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0023] like Figures 1 to 3 The bottom-folding box-pushing machine shown mainly comprises a supporting assembly 1, a bearing assembly 2, a limiting assembly 3, a bottom-folding assembly 4 and a material-pushing assembly 5, etc., which are matched with each other.

[0024] The support assembly 1 includes a support frame 11, a plurality of support legs 12 installed at the bottom of the support frame 11 (usually four support legs 12 are located at the four corners of the bottom of the support frame 11), a reinforcing rod 13 installed between two adjacent support legs 12, and a roller 14 installed at the bottom of each support leg 12.

[0025] The bearing assembly 2 at least includes a supporting flat plate 23 mounted on the supporting assembly 1 (usually in the supporting frame 11, the same below) for placing the packaging box. The bearing assembly 2 also includes a supporting transverse plate 21 mounted on the supporting assembly 1 and arranged vertically (the supporting transverse plate 21 is formed on the bottom surface of the supporting flat plate 23, that is, the supporting flat plate 23 is fixed on the supporting transverse plate 21 and is perpendicular to it) and bottom-stopping rollers 22 mounted on the ends of both sides of the supporting transverse plate 21 (ends located downstream of the supporting transverse plate 21) and cooperating with the bottom folding assembly 4 (so that when the packaging box is folded, the bottom-stopping rollers 22 can be used to stop the bottom of the packaging box to prevent the bottom of the packaging box from opening).

[0026] The limiting assembly 3 is installed on the supporting assembly 1 to maintain the placement state of the packaging box. The limiting assembly 3 includes two limiting rods 31 symmetrically arranged above the supporting plate 23 and matched therewith (the two limiting rods 31 are located on both sides of the packaging box to abut against its two side surfaces to ensure the stable placement of the packaging box), two transfer flaps 32 connected to the ends of the limiting rods 31 in a one-to-one correspondence, and a limiting driving mechanism connected to the two transfer flaps 32 to drive them to move toward or away from each other. The limit drive mechanism includes a first transmission shaft 37 rotatably mounted on the support assembly 1 (such as being mounted on the support frame 11 through a bearing and penetrating the side wall thereof) and having first pulleys mounted on both ends, a first motor 39 connected to a first pulley through a first belt 38 for driving the rotation thereof, a second pulley mounted in the support assembly 1, a second belt 34 wound around another first pulley and the second pulley, a slide rail 36 mounted in the support assembly 1, and two first sliders 35 slidably mounted on the slide rail 36 and connected to the second belt 34, two transfer folding plates 32 being mounted on the two first sliders 35 in a one-to-one correspondence, and the two first sliders 35 being located on the upper and lower sides of the second pulley. In this way, the limit drive mechanism no longer requires an air source, but only requires an external power supply, which is conducive to improving reliability and stability. When in use, the first motor 39 works and drives the first transmission shaft 37 to rotate synchronously through the first belt 38, and then drives the second belt 34 to rotate synchronously, so that the two transfer folding plates 32 move toward or away from each other, and the two limit rods 31 also move toward or away from each other, so that the packaging box can be clamped or released.

[0027] The folding bottom assembly 4 at least includes two folding bottom rods 44 symmetrically arranged below the supporting plate 23 and matched therewith, and a driving unit connected to the folding bottom rods 44 one by one for driving them to move toward or away from each other. The driving unit includes a plurality of guide rods 40 (two in this embodiment) installed in the supporting assembly 1 (also in the supporting frame 11) and perpendicular to the folding bottom rods 44, two slide plates 42 slidably installed on the guide rods 40 through a sliding sleeve 41, a support member 43 installed on each slide plate 42 and connected to a folding bottom rod 44, an adapter member 45 installed at the bottom of each slide plate 42, a second transmission shaft 47 rotatably installed on the supporting assembly 1 (usually installed on the auxiliary structure of the supporting frame 11 through a bearing) and having third pulleys installed at both ends, and a third belt 48 connected to a The third pulley is connected to a second motor 49 for driving its rotation (the second motor 49 can be directly mounted on the inner wall of the support frame 11, or indirectly mounted on the support frame 11 through an existing conventional support structure (i.e., the aforementioned auxiliary structure), and the auxiliary structure is provided to facilitate the installation of the second transmission shaft 47 and the second motor 49), a fourth pulley mounted in the support assembly 1 (i.e., on the inner wall of the support frame 11), and a fourth belt 46 wound around another third pulley and a fourth pulley and connected to the adapter 45, and two adapters 45 are located on both sides of the fourth pulley. Similarly, the second motor 49 works and drives the second transmission shaft 47 to rotate synchronously through the third belt 48, and then drives the fourth belt 46 to rotate synchronously, so that the two adapters 45 move toward or away from each other, and the two bottom folding rods 44 also move toward or away from each other through the slide plate 42 and the support member 43, so that the bottom folding of the two bottom plates of the packaging box can be achieved.

[0028] The pushing assembly 5 is arranged above the supporting plate 23 and is used to push the bottom-folded packaging box downstream. The pushing assembly 5 includes a third transmission shaft 52 rotatably mounted on the supporting assembly 1 (such as being mounted on the supporting frame 11 through a bearing and passing through its side wall) and having fifth pulleys mounted on both ends, a third motor 50 connected to a fifth pulley through a fifth belt 51 for driving the fifth pulley to rotate, a sixth pulley connected to another fifth pulley through a transmission rod 57 (the sixth pulley rotates synchronously with the fifth pulley), two seventh pulleys 53 mounted in the supporting assembly 1 (i.e., on the inner wall of the supporting frame 11), two eighth belts 54 wound around another fifth pulley and a seventh pulley 53 and around the sixth pulley and another seventh pulley 53 (i.e., there are two eighth belts 54, which are rotatably mounted on the inner wall of the supporting frame 11, spaced apart and arranged thereto), and a material-diverting plate 56 mounted on the two eighth belts 54 through a transfer block 55 and perpendicular to the supporting flat plate 23, the material-diverting plate 56 having a material-diverting protrusion 561 in the middle portion for diverting the packaging box after folding the bottom to move downstream. The material stripping plate 56 is located between the support plate 23 and the limit rod 31. The third motor 50 can be controlled by a controller in a delayed start mode, or by a sensor sending a signal to the controller to control its operation, as long as the bottom folding box pushing machine can be automatically operated.
