[0002] Cake cup holders are paper cups used to make cakes, such as tulip cups, and paper cups are produced and formed by paper cup forming machines. Paper cup machines are machines that mechanically process and fold paper sheets made of chemical wood pulp into paper cups. During the processing of the paper cup machine, the paper sheet is first taken out by the paper taking mechanism and placed in the lower mold, and then the upper mold is pressed into the lower mold to fold the paper sheet into a cup-shaped structure. Then the lower mold rotates to fold the folded edge of the paper cup toward the cup body, and then the upper mold takes out the paper cup and presses it into another lower mold to compact the folded edge of the paper cup. Finally, the upper mold takes out the formed paper cup and discharges the material, but The existing paper cup machine is arranged vertically as a whole, and the paper picking mechanism and the upper mold are arranged on the same plane and move synchronously. In this way, the paper picking mechanism needs to wait for the upper mold to complete the paper pressing action and reset before continuing the paper picking action. Similarly, the upper mold also needs to wait for the paper picking mechanism to complete the paper placing action and reset before continuing the paper pressing process, which increases the time for picking up and placing paper sheets and paper pressing.

Figures 1 to 5 As shown, the tensioning wheel 22 can provide tension to the transmission chain 21. After the upper mold 11 presses the paper skin into the lower mold 7, the driving motor 18 drives the driving wheel 20 to rotate, and the driving wheel 20 drives the sprocket 19 to rotate through the transmission chain 21. The sprocket 19 drives the linkage gear 23 to rotate through the rotating shaft, and the linkage gear 23 drives the lower mold 7 to rotate, so that the lower mold 7 can fold the folded edge on the paper cup.

[0025] Further, a mold core is provided in the lower mold 7, and a molding groove 25 whose diameter gradually decreases toward the mold core is provided on the right side of the lower mold 7, and a plurality of strip-shaped slots 26 are provided in the molding groove 25, wherein the lower paperboard 8 includes three, and the three lower paperboards 8 are arranged on the mounting frame 3 through a transverse plate, and the right side of the top end of the lower paperboard 8 is bent toward the paper bin 6, as shown in FIG. Figures 1 to 5 As shown, the top of the lower paperboard 8 is bent to facilitate the paper sheet to slide into the lower paperboard 8. When the upper mold 11 drives the paper sheet to be pressed into the lower mold 7, the paper sheet is gradually formed into a paper cup shape in the molding groove 25, and the paper sheet forms an outwardly protruding folded edge along the strip groove 26. After the paper sheet is formed, the driver drives the lower mold 7 to rotate 90° and folds the folded edge toward the paper cup.

[0026] Furthermore, the upper mold 11 includes three, a plurality of slide bars 27 are arranged on the mounting frame 3, the ejector includes a servo motor 28, a transmission seat 29 and a mounting plate 30, the three upper molds 11 are arranged on the mounting plate 30, and the mounting plate 30 is slidably connected with the plurality of slide bars 27 through a plurality of sliding sleeves, the servo motor 28 and the transmission seat 29 are arranged on the right side of the mounting frame 3, and the output end of the servo motor 28 is connected to the transmission seat 29, the front and rear sides of the transmission seat 29 are rotatably connected with a rocker arm 31, and the rocker arm 31 is hinged to the mounting plate 30 through a connecting rod 32, wherein a plurality of adsorption holes 33 are arranged at the left end of the upper mold 11, and the upper mold 11 is provided with a vacuum tube connected to the plurality of adsorption holes 33, a spring seat 34 is slidably connected to the right side of the mounting plate 30, the spring seat 34 is connected to the mounting plate 30 through a compression spring, and the spring seat 34 is hinged to the connecting rod 32, as shown in FIG. Figures 1 to 5 As shown, a conventional transmission structure in which a worm gear (not shown in the figure) cooperates can be adopted in the transmission seat 29, so it is not described in detail. A clearance groove can be set on the right side of the mounting frame 3 to facilitate the movement of the connecting rod 32. The output end of the servo motor 28 can be connected to the worm, and the rocker arm 31 can be connected to the turbine through a connecting shaft. The servo motor 28 drives the rocker arm 31 to rotate through the transmission seat 29. The rotation of the rocker arm 31 drives the connecting rod 32 to move left and right, and the connecting rod 32 drives the mounting plate 30 to move along the slide bar 27. In this way, the pusher can drive the upper mold 11 to press the paper sheet into the lower mold 7 for molding. The compression spring and the spring seat 34 on the mounting plate 30 cooperate to form a buffer after the upper mold 11 is pressed into the lower mold 7 to avoid excessive extrusion between the upper mold 11 and the lower mold 7. This is a conventional buffer structure and is not described in detail. After the mold 7 rotates to fold the edge of the paper cup, the pusher drives the upper mold 11 to move and press the paper cup and the folded edge again. The servo motor 28 has the function of metering and accurate positioning, so the staff can set multiple strokes for the upper mold 11. After the paper cup is formed, the vacuum tube (not shown in the figure) on the upper mold 11 works and causes the adsorption hole 33 to generate suction. The vacuum tube can be connected to an external vacuum generator (not shown in the figure), so that the upper mold 11 can absorb the paper cup so that the upper mold 11 can take the paper cup out of the lower mold 7. After the paper cup is separated from the lower mold 7, the vacuum tube stops working and the suction of the adsorption hole 33 disappears, and the paper cup falls from the upper mold 11 to the storage tank 2 for storage. The staff can set the size of the upper mold 11 to be smaller than the size of the paper cup so that the paper cup falls under the action of its own weight after the adsorption force of the upper mold 11 disappears.
