DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0018] Example 1 A plastic sheet automatic counting and bagging device, such as Figure 1-Figure 6 As shown, it includes a mounting frame 1, a charging box 2, an electric slicer 3, an electric lift 4, an electric conveyor 5, an inclined positioning platform 61, a discharge cylinder 62, an electric lifting push rod 7, a pressing plate 71 and an electronic counter 8; the charging box 2, the electric slicer 3 and the electric lift 4 are sequentially mounted on the mounting frame 1, and the feeding area of ​​the electric lift 4 is aligned with the unloading port of the charging box 2, and the discharging area of ​​the electric lift 4 is aligned with the feeding port of the electric slicer 3; the electric conveyor 5 is mounted on the mounting frame 1; the discharging port of the electric slicer 3 is fixedly connected with an inclined plate 31 inclined toward the direction of the electric conveyor 5; the mounting frame 1 is fixedly connected with an inclined surface positioning platform 61 which is close to the discharge port of the electric conveyor 5, and the upper surface of the inclined surface positioning platform 61 is set as an inclined surface structure which is inclined downward toward the side away from the electric conveyor 5; a discharge barrel 62 is fixedly connected in the inclined surface positioning platform 61; an alignment limit plate 611 which is aligned with the upper side of the discharge barrel 62 is provided on the inclined surface structure of the inclined surface positioning platform 61; an electric lifting push rod 7 is installed on the mounting frame 1; a pressing plate 71 is connected to the telescopic end of the electric lifting push rod 7, and the pressing plate 71 is located just above the discharge barrel 62; an electronic counter 8 for counting the plastic sheets that slide down is installed on the inclined surface positioning platform 61.

[0019] like Figure 4As shown, two symmetrical supporting slides 63 are slidably connected to the inclined positioning platform 61; two electric telescopic push rods 64 are installed on the inclined positioning platform 61; the telescopic ends of the two electric telescopic push rods 64 are respectively fixed to the corresponding supporting slides 63; the upper surfaces of the two supporting slides 63 are in an inclined state flush with the upper surface of the inclined positioning platform 61.

[0020] The working steps of a plastic sheet automatic counting and bagging device are as follows.

[0021] After the staff puts the bag mouth on the discharge barrel 62, the plastic sheets that have been cut are poured into the loading box 2, and the electric lift 4 automatically sends the plastic sheets in the loading box 2 into the electric sheet splitter 3 in batches. The electric sheet splitter 3 then sends the plastic sheets one by one along the inclined plate 31 to the electric conveyor 5, and the electric conveyor 5 conveys the plastic sheets to the inclined positioning platform 61. The plastic sheets slide along the inclined positioning platform 61 onto the two supporting slides 63 and are in an inclined state. When the plastic sheets are aligned with the limit plate 6 11, the bottom edge of the plastic sheet is aligned with the two supporting slides 63, and the plastic sheet is aligned with the bottom of the pressing plate 71, and the electronic counter 8 counts the plastic sheets passing under it. Then, the two electric telescopic push rods 64 respectively pull the supporting slides 63 connected to them to move away from the inclined positioning platform 61 and leave the bottom of the plastic sheet, and the electric lifting push rod 7 pushes the pressing plate 71 to drive the plastic sheet below it downward through the discharge barrel 62 and into the bag, completing the automatic bagging of the plastic sheets.

[0022] Example 2 On the basis of Example 1, Figure 1-Figure 6 As shown, the discharge barrel 62 of this embodiment is provided with an annular protrusion 65 for opening the bag mouth of the bag; the pressing plate 71 is rotatably connected to the telescopic end of the electric lifting push rod 7 through a rotating shaft; the telescopic end of the electric lifting push rod 7 is rotatably connected to the electric adjusting push rod 72 through a rotating shaft; the telescopic end of the electric adjusting push rod 72 is rotatably connected to the pressing plate 71 through a rotating shaft; an electric heating module for heating the bottom area of ​​the pressing plate 71 is installed in the pressing plate 71; an exhaust pipe valve 73 is installed on the pressing plate 71, and the exhaust pipe valve 73 is externally connected to a suction machine; a plurality of exhaust hole structures 730 connected to the exhaust pipe valve 73 are provided at the bottom of the pressing plate 71, and the exhaust hole structures 730 are equidistantly distributed on the bottom edge of the pressing plate 71.

[0023] After the staff puts the bag mouth on the annular protrusion 65 of the discharge barrel 62, the plastic sheet slides along the inclined positioning platform 61 onto the two supporting slides 63 and is in an inclined state. Under the alignment of the alignment limit plate 611, the bottom edge of the plastic sheet is aligned with the two supporting slides 63. During this process, the electric heating module keeps heating the bottom of the pressing plate 71. Then the electric adjustment push rod 72 pulls the pressing plate 71 to flip counterclockwise at the front viewing angle, so that the pressing plate 71 flips to an inclined state parallel to the plastic sheet on the two supporting slides 63, and then the electric lifting push rod 7 The inclined pressing plate 71 is pushed downward to press tightly against the surface of the plastic sheet located on the two supporting slides 63. Since the edge area of ​​the plastic sheet is locally bent, squeezed and deformed during the production and transportation process, the edge area of ​​the plastic sheet can be heat-pressed and flattened by the heated pressing plate 71. At the same time, the two supporting slides 63 jointly provide support for the plastic sheet. At the same time, an external suction machine performs suction on the edge area of ​​the plastic sheet through the suction hole structure 730 of the suction pipe valve 73, so that the edge area of ​​the plastic sheet that is heat-pressed and flattened is tightly attached to the suction hole structures 730 of the pressing plate 71.

[0024] Afterwards, the two electric telescopic push rods 64 respectively pull the supporting slide 63 connected to them to move away from the inclined positioning platform 61 and away from the bottom of the plastic sheet, and the electric adjustment push rod 72 pushes the pressing plate 71 to drive the plastic sheet close to its bottom to rotate clockwise at the front viewing angle to return to the horizontal state. At the same time, the electric lifting push rod 7 pushes the pressing plate 71 to drive the plastic sheet close to its bottom downward through the discharge barrel 62 and into the bag. In this process, the edge area of ​​the plastic sheet that has been heat-pressed and flattened is kept in a state of being close to the bottom of the pressing plate 71 under the suction action of the exhaust hole structure 730, and the heated pressing plate 71 performs heat-setting treatment on the edge area of ​​the plastic sheet that has been heat-pressed and flattened, so that the plastic sheet is fixed into a complete and standard flat state without bending. Afterwards, the exhaust pipe valve 73 no longer performs suction work on the plastic sheet close to the pressing plate 71, so that the plastic sheet that has completed the heat-setting treatment remains in the bag to complete the automatic bagging work.

[0025] Example 3 On the basis of Example 2, Figure 1-Figure 6 As shown, an air blowing pipe valve 74 is installed on the pressing plate 71 of this embodiment, and the air blowing pipe valve 74 is externally connected to a blower; a plurality of air blowing hole structures 740 connected to the air blowing pipe valve 74 are provided at the bottom of the pressing plate 71; an electric lifting slider 91 is slidably connected to the mounting frame 1; a carrier plate 92 is fixedly connected to the electric lifting slider 91, and the carrier plate 92 is located directly below the discharge barrel 62; an annular protrusion 65 is slidably connected to the discharge barrel 62; a plurality of spring pieces 66 are fixedly connected to the outer ring surface surrounding the discharge barrel 62, and the spring pieces 66 are made of metal sheet material, and the spring pieces 66 are all tightly attached to the inner side of the annular protrusion 65; the bag of this embodiment is made of nylon reinforced material that is not easily scratched by the spring pieces 66 made of metal sheet material.

[0026] Before putting the bag mouth on the discharge barrel 62, the staff first places the bag on the carrier 92, and then pushes the annular protrusion 65 to move downward along the discharge barrel 62. At the same time, the annular protrusion 65 presses the lower ends of all the spring pieces 66 downward to close to the inner wall of the discharge barrel 62. The staff then presses the bag mouth onto the discharge barrel 62 and the annular protrusion 65, and folds the excess area of ​​the bag upward on the discharge barrel 62. Then the staff pushes the annular protrusion 65 to move upward along the discharge barrel 62. At this time, the lower end of the spring piece 66 leaves the annular protrusion 65 and quickly pops outward. All the spring pieces 66 that pop out together expand the bag mouth mounted on the annular protrusion 65 outward to clamp it, thereby strengthening the firm clamping effect of the bag mouth on the annular protrusion 65.

[0027] The bag 72 is then opened and the bag is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag 72 is in a closed position, and the bag
