[0048] See also Figure 1 In some possible embodiments, a flip assembly 4 is provided on the front side / rear side of the support base 1 along the second direction, and the flip assembly 4 is connected to the side of the stacking platform 2 close to the output end. The flip assembly 4 is used to pull the stacking platform 2 to flip around its hinged side to the storage table 11.

[0049] The flip assembly 4 is used to drive the stacking platform 2 to flip onto the storage table 11 so as to transfer the plastic products onto the storage table 11. Optionally, the flip assembly 4 can be arranged at the front side or at the rear side, or a group of flip assemblies 4 can be arranged at the front side and the rear side respectively; the specific arrangement can be selected according to actual needs.

[0050] See also Figure 2In some embodiments, the flip assembly 4 includes a first tensioning wheel 41, a second tensioning wheel 42 and a tensioning belt 43, and a first drive motor 44; the first tensioning wheel 41 is arranged on the front side of the stacking platform 2 along the second direction and close to the output end; the second tensioning wheel 42 is arranged on the support seat 1 and away from the stacking platform 2 in the first direction; one end of the tensioning belt 43 is fixed on the first tensioning wheel 41, and the other end passes around the first tensioning wheel 41 and is wrapped around the second tensioning wheel 42; the first drive motor 44 is arranged in the support seat 1; the power output end of the first drive motor 44 is connected to the second tensioning wheel 42.

[0051] After the plastic products on the stacking platform 2 are stacked to a preset height, the first drive motor 44 drives the second tensioning wheel 42 to rotate, so as to tighten the tensioning belt 43, and pulls the first tensioning wheel 41 to rotate toward the second tensioning wheel 42, so that the second tensioning wheel 42 drives the stacking platform 2 to flip over to the storage table 11, thereby transferring the plastic products on the stacking platform 2 to the storage table 11.

[0052] Optionally, a plurality of second tensioning wheels 42 are provided, and the plurality of second tensioning wheels 42 are arranged on the support seat 1 at intervals in the vertical direction; the tensioning belt 43 passes around the plurality of second tensioning wheels 42 in sequence and is fixed on the second tensioning wheel 42 at the lower end, and is connected to the second tensioning wheel 42 at the lower end fixed with the tensioning belt 43 and the power output end of the first drive motor 44.

[0053] Specifically, two second tensioning wheels 42 are provided, one of which is located on the support seat 1 and is spaced apart from the first tensioning wheel 41 along the first direction, and the other is vertically located above the above-mentioned second tensioning wheel 42 and is flush with the flipped stacking platform 2, for realizing the reversal of the tensioning belt 43.

[0054] See also Figure 2 For example, a torsion spring 24 is provided on the hinged side of the stacking platform 2, one end of the torsion spring 24 is fixed to the side of the stacking platform 2, and the other end is fixed to the support base 1; the torsion spring 24 is used to reset the stacking platform 2 under the flattening assembly 3.

[0055] By providing the torsion spring 24, on the one hand, the stacking platform 2 can be smoothly lowered to the storage table 11 under the pressing action of the torsion spring 24, and on the other hand, the stacking platform 2 can be reset to below the flattening assembly 3 after the plastic product is completely overturned.

[0056] See also Figure 1 or Figure 2 In some possible embodiments, two groups of limiting columns 5 are provided on the stacking platform 2 along the first direction, and a receiving space for stacking plastic bag products is defined between the two groups of limiting columns 5; and an annular pressure head 51 is provided at the top of each group of limiting columns 5 and is disposed toward the receiving space.

[0057] By setting up the accommodating space, the plastic products can be limited in a small range first to prevent the plastic products from scattering on the stacking platform 2; and by setting up the limiting column 5, during the flipping process of the stacking platform 2, the plastic products can be pressed tightly on the stacking platform 2 with the help of the annular pressure head 51 to prevent the plastic products from slipping, thereby ensuring the flatness between the plastic products.

[0058] See also Figure 3 In some embodiments, a first accommodating cavity 21 is provided in the stacking platform 2, and two groups of giving way grooves 22 corresponding to the limiting columns 5 are provided on the top of the stacking platform 2, the giving way grooves 22 are communicated with the first accommodating cavity 21, and extend along the first direction; a rotating assembly 6 is provided in the first accommodating cavity 21, and the lower ends of the two groups of limiting columns 5 extend into the first accommodating cavity 21 from the corresponding giving way grooves 22, and are respectively connected to the power output ends of the rotating assembly 6; wherein, when the rotating assembly 6 drives the limiting column 5 to swing to the side of the giving way groove 22 away from the accommodating space, the limiting column 5 is in a giving way state away from the plastic product; when the rotating assembly 6 drives the limiting column 5 to swing to the side close to the accommodating space, the annular pressure head 51 of the limiting column 5 is pressed tightly on the stacked plastic product to form a limiting state.

[0059] By providing the clearance groove 22, it is convenient for the lower end of the limiting column 5 to pass into the first accommodating cavity 21 and connect with the rotating component 6, and the rotation range of the limiting column 5 is limited; by providing the rotating component 6, the rotation of the limiting column 5 is realized, thereby realizing the limitation of the plastic product.

[0060] It should be understood that when the plastic products are conveyed to the stacking platform 2, the limit column 5 swings to the side of the make way groove 22 away from the accommodating space and is in a make way state, while facilitating the flattening component 3 to flatten the plastic products downward; when the stacking platform 2 needs to be flipped over, the limit column 5 is in a limit state, which is used to press the plastic products to prevent relative slippage between the plastic products, or to prevent them from sliding onto the storage table 11.

[0061] Furthermore, a plurality of clearance spaces suitable for the limiting columns 5 to pass through are arranged on the storage platform 11 , and the plurality of clearance spaces correspond to the plurality of groups of limiting columns 5 one by one.

[0062] See also Figure 3Exemplarily, the rotating assembly 6 includes a second driving motor 61, two sets of driving gears 62, two sets of moving racks 63 and two sets of first gears 64; the second driving motor 61 is arranged in the first accommodating cavity 21 and is placed between the two sets of limiting columns 5; the two sets of driving gears 62 are arranged at the power output end of the second driving motor 61 at intervals along the second direction; the two sets of moving racks 63 are arranged in the first accommodating cavity 21 at intervals along the second direction; one end of the two sets of moving racks 63 is meshed with the two sets of driving gears 62 in a one-to-one manner, and the other end extends in the opposite direction along the first direction; the two sets of first gears 64 are arranged in the first accommodating cavity 21, and are connected to the lower ends of the two sets of limiting columns 5 in a one-to-one manner; the two sets of first gears 64 are meshed with the extended ends of the two sets of moving racks 63 in a one-to-one manner.

[0063] The second driving motor 61 is used to drive the corresponding moving rack 63 to slide through two sets of driving gears 62. When the moving rack 63 slides along the first direction, the first gear 64 rotates, thereby driving the limiting column 5 on the top of the first gear 64 to swing accordingly, thereby achieving the purpose of swinging the limiting column 5 in the give way slot 22.

[0064] Specifically, among the two groups of limiting columns 5, one group of limiting columns 5 is only provided with one first limiting column; the other group of limiting columns 5 includes two second limiting columns spaced apart along the second direction, and in the second direction, the first limiting column is placed between the two first limiting columns.

[0065] Similarly, each first limiting column and each second limiting column respectively corresponds to a first gear 64 , each first gear 64 corresponds to a moving rack 63 , and when the three moving racks 63 slide, there will be no interference between them, and each moving rack 63 corresponds to a driving gear 62 .

[0066] See also Figure 3 In some embodiments, two groups of slide grooves 23 are provided at the bottom of the first accommodating chamber 21 , and two groups of movable racks 63 are correspondingly slidably connected in the two groups of slide grooves 23 .

[0067] The sliding groove 23 is provided to guide the sliding of the movable rack 63 , thereby preventing the movable rack 63 from being offset during the sliding process and affecting the meshing with the first gear 64 and the driving gear 62 .

[0068] See also Figure 1 In some possible embodiments, the flattening assembly 3 includes a telescopic driving member 31 and a pressure seat 32; the telescopic driving member 31 is arranged on the support seat 1, and the telescopic end of the telescopic driving member 31 extends downward; the pressure seat 32 is arranged at the telescopic end of the telescopic driving member 31; and a plurality of groups of pressure wheels 323 are arranged at intervals at the bottom of the pressure seat 32.

[0069] Optionally, the telescopic driving member 31 is a telescopic cylinder, a telescopic hydraulic cylinder or an electric push rod.

[0070] The telescopic drive member 31 is used to drive the pressing seat 32 to extend and retract upward and downward so that the pressing seat 32 can press the plastic product downward. It should be understood that the plastic product is relatively thin and light. If the bottom plate of the pressing seat 32 is directly used to press downward, the plastic product may be moved when the pressing seat 32 rises. In the present application, multiple groups of pressing wheels 323 are arranged at the bottom of the pressing seat 32 to prevent the plastic product from moving with it when the plastic product is pressed.

[0071] See also Figure 4 In some embodiments, the pressure seat 32 and the power output end of the telescopic driving member 31 are connected through a connecting column 33, and a vertically extending first channel 331 is provided in the connecting column 33; a second accommodating cavity 321 communicating with the first channel 331 is provided in the pressure seat 32, and a plurality of air holes 322 are arranged in an array at the bottom of the pressure seat 32, and the plurality of air holes 322 are all communicated with the second accommodating cavity 321; an air pump 7 is provided on the support seat 1, and an air outlet end of the air pump 7 is communicated with the first channel 331 through a telescopic pipe 71; when the pressure seat 32 approaches the plastic product downward, the airflow discharged by the air pump 7 through the air hole 322 blows the plastic product flat.

[0072] In the present application, an air pump 7 is provided so that the air pump 7 can deliver the airflow from the telescopic pipe 71 to the first channel 331 of the connecting column 33, and discharge it evenly through the air hole 322 with the help of the second accommodating cavity 321 of the pressure seat 32, so as to be blown downward to the surface of the plastic product.

[0073] Optionally, multiple groups of pressure wheels 323 are distributed on the outer edges of multiple air holes 322; it should be understood that when the pressure seat 32 is extended and retracted downward under the drive of the telescopic drive member 31, the airflow is blown downward to the center of the plastic product, and moves along the center to the outer edge of the plastic product, so that the plastic product is stretched and flattened from the center to the outer edge, and the indentation wrinkles are blown away. Then, when the pressure wheel 323 on the pressure seat 32 is pressed down onto the plastic product, the plastic product is flattened, which can achieve double flattening of the plastic product, reduce wrinkles and indentations, and improve flatness and aesthetics.

[0074] Optionally, the telescopic pipe 71 can be a hose, one end of which is connected to the air supply end of the air pump 7, and the other end is fixed to the connecting column 33 and extends into the first channel 331. The hose has a certain length and can move up and down with the pressure seat 32; or the telescopic tube is a rubber corrugated tube, which can be freely extended and retracted to adapt to the up and down movement of the pressure seat 32.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
