The bottom of the push block 112 is arranged corresponding to the transfer platform 110 along the third direction and is connected to the mover of the linear motor 111 for driving the push block 112 to push the square boxes 2 to be transferred into the loading flap 170 along the first direction through the linear motor 111.

[0039] Exemplarily, the linear motor 111 directly drives the push block 112, reducing the number of transmission components, lowering the complexity and failure rate of the equipment. In addition, the linear motor 111 can provide a large thrust, can achieve higher speeds and accelerations, and ensure the stability of the push block 112 when pushing a large number of stacked square boxes 2.

[0040] In some embodiments, referring to Figures 1 to 7 , the feed bin 100 includes a fixed plate 102, a left baffle 103, a right baffle 104, a front baffle 105, and a rear baffle 106. The fixed plate 102 is respectively disposed on both sides of the feed bin 100 along the first direction, and is connected to the left fixed plate 107 and the right fixed plate 108 at both ends along the third direction. Both the left baffle 103 and the right baffle 104 extend along the second direction. The left baffle 103 is spaced from the left fixed plate 107 along the third direction, and the right baffle 104 is spaced from the right fixed plate 108 along the third direction, and both are provided with a moving interval corresponding to the fork transfer assembly 14. Both ends of the left baffle 103 and the right baffle 104 along the first direction are connected to the fixed plate 102. The front baffle 105 and the rear baffle 106 are spaced from each other along the first direction, and are connected to the fixed plate 102 on the opposite sides along the first direction. The tops of the front baffle 105 and the rear baffle 106 are bent toward the opposite sides along the first direction to cooperate to form the feed end 101.

[0041] Exemplarily, the front baffle 105 and the rear baffle 106 are spaced from each other along the first direction, and the tops are bent toward the opposite sides along the first direction to form the feed end 101. This design can better guide the material into the feed bin 100, reduce the accumulation of the material at the feed port, and improve the feeding efficiency. The design of the feed bin 100 can adapt to materials of different sizes by adjusting the intervals between multiple baffles, and has good versatility. Both ends of the square box 2 are supported by two corresponding loading forks 140 or two unloading forks 141 along the third direction. Among them, the fork plate 148 in the telescopic assembly 145 enters the feed bin 100 through the moving interval and abuts against the edge of the square box 2 to carry the entire square box 2; when the fork plate 148 exits the feed bin 100, the multiple square boxes 2 carried above fall freely, changing from being carried by the loading fork 140 to being carried by the unloading fork 141, or from being carried by the unloading fork 141 to being carried by the transition platform 110.

[0042] Furthermore, counting sensors 114 are provided on the tops of the front baffle 105 and the rear baffle 106, as well as on the top of the transition platform 110, for counting and controlling the number of square boxes 2 collected.

[0043] In some embodiments, referring to Figures 1 to 7, the feeding platform 10 further includes a brush accelerating mechanism 115 and a blowing pipe 119. The brush accelerating mechanism 115 is disposed above the feeding end 101 and includes a connecting housing 116, a brush synchronous pulley belt mechanism 117, and a driving motor 118. The brush synchronous pulley belt mechanism 117 extends along the first direction, and the driving motor 118 is disposed on one side of the brush synchronous pulley belt mechanism 117 along the third direction for driving the brush synchronous pulley belt mechanism 117 to drive, so as to quickly drive the square box 2 to the feeding end 101 of the feeding bin 100 by frictional contact with the surface of the square box 2. The connecting housing 116 covers the brush synchronous pulley belt mechanism 117 and the driving motor 118 and is connected to the left fixing plate 107. The blowing pipe 119 is disposed on the top of the connecting housing 116 and above the feeding end 101. The blowing direction of the blowing pipe 119 faces into the feeding bin 100 and is used to assist in accelerating the falling of the square box 2 to achieve rapid stacking and nesting.

[0044] Exemplarily, the brush accelerating mechanism 115 can adapt to square boxes 2 of different sizes, drive the brush to rotate and rub against the surface of the square box 2, quickly drive the square box 2 to the feeding end 101 of the feeding bin 100, and cooperate with the blowing pipe 119 to achieve a dual acceleration function, significantly improving the feeding speed and stacking efficiency of the square box 2, thereby enhancing the production efficiency of the entire feeding platform 10.

[0045] In some embodiments, referring to Figures 1 to 7 , the mobile feeding device 16 further includes a surrounding plate 165 and a connecting member 166. The surrounding plate 165 extends along the fourth direction, is located above the pushing device 19, and is respectively disposed at positions on both sides of the protection housing 163 along the third direction that do not correspond to the receiving bin 18 for cooperating to block when the loading flap 170 moves. The connecting member 166 is disposed on the side of the surrounding plate 165 along the third direction away from the protection housing 163 and is spaced along the fourth direction, with both ends respectively connecting the surrounding plate 165 and the side wall of the protection housing 163.

[0046] Exemplarily, by providing the surrounding plate 165 to block the loading flap 170, materials that may fall during the moving process are prevented, ensuring the stability of the square box 2 during transportation. Both ends of the connecting member 166 are respectively connected to the surrounding plate 165 and the side wall of the protection housing 163, preventing the surrounding plate 165 from being displaced or deformed during use.

[0047] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall fall within the protection scope of the present invention.
