Description

Technical Field

[0001] The utility model relates to the technical field of paper cup machines, in particular to a tulip cup paper cup machine. Background Art

[0002] Cake cup holders are paper cups used to make cakes, such as tulip cups. 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, the paper sheet is first taken out by the paper taking mechanism and placed into the lower mold. The upper mold is then pressed into the lower mold to fold the paper sheet into a cup-shaped structure. The lower mold then rotates to fold the edge of the paper cup toward the cup body. The upper mold then takes out the paper cup and presses it into another lower mold to tighten the folded edge of the paper cup. Finally, the upper mold takes out the formed paper cup and discharges it. The existing paper cup machine is arranged vertically as a whole. 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 it can continue to pick up paper. Similarly, the upper mold also needs to wait for the paper picking mechanism to complete the paper placing action and reset before it can continue to press paper. This increases the time for picking up and placing paper and pressing paper. In addition, the upper mold needs to transport the paper between the two lower molds for two paper pressing processes, which increases the moving stroke of the upper mold and the paper, thereby increasing the time required for the entire processing process and reducing the overall processing efficiency.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0021] like Figures 1 to 5 As shown, a tulip cup paper cup machine includes a frame 1, a paper picking mechanism and a die pressing mechanism. The frame 1 is provided with a material storage trough 2, and the frame 1 is provided with a mounting frame 3 above the material storage trough 2. The paper picking mechanism includes a bracket 4, a paper picker 5 and a paper bin 6. The bracket 4 and the paper bin 6 are arranged on the top surface of the mounting frame 3. The paper picker 5 is slidably connected to the bracket 4 and can take out paper sheets from the paper bin 6 in the horizontal direction. The inner side of the mounting frame 3 is rotatably connected to the lower die 7, and one side of the mounting frame 3 is connected to the lower die 7. A driver for driving the lower mold 7 to rotate is provided on the outside, and a lower cardboard 8 located at the material port of the lower mold 7 is provided on an inner side of the mounting frame 3. The top of the lower cardboard 8 is provided with a lower paper groove 9 that can receive paper pieces dropped from the paper picker 5, and the lower cardboard 8 is provided with a through groove 10 connected to the lower paper groove 9 and the lower mold 7. The pressing mechanism includes an upper mold 11 and a pusher. The upper mold 11 is slidably connected to the mounting frame 3, and the pusher is connected to the upper mold 11 and drives the upper mold 11 to press into the lower mold 7.

[0022] The working principle of the tulip cup paper cup machine described in the present invention is achieved through the cooperation between the frame 1, the paper taking mechanism and the die pressing mechanism. Figures 1 to 3As shown, the paper picking mechanism, the upper mold 11 and the lower mold 7 are staggered up and down. The output end of the paper picker 5 extends out and takes paper from the paper bin 6, driving the paper piece to move above the lower cardboard 8, that is, the paper piece is aligned with the lower paper slot 9 of the lower cardboard 8. Then the paper picker 5 releases the paper piece, and the output end of the paper picker 5 releases the paper skin and continues to extend to the paper bin 6 to take paper. The falling paper piece falls along the lower paper slot 9 of the lower cardboard 8 to the position of the through slot 10. Then the pusher drives the upper mold 11 to extend from the through slot 10 into the lower cardboard 8 and press the paper piece into the lower mold 7 to form it into a paper cup shape. Then the driver drives the lower mold 7 to rotate and folds the folded edge of the outer side of the paper cup, and the pusher drives the upper mold 11 to press the paper again Cup, and finally the pusher drives the upper mold 11 to reset and take out the formed paper cup and make it fall into the storage trough 2. Compared with the traditional paper cup machine, the paper picking mechanism, lower mold 7 and upper mold 11 of the tulip cup paper cup machine are arranged horizontally. In this way, the paper picker 5 and the upper mold 11 work independently. After the paper picker 5 takes out the paper skin, it can put paper and reset again to take out the paper skin. The paper picker 5 does not need to wait for the upper mold 11 to complete the paper pressing process and reset before taking paper. The upper mold 11 also does not need to wait for the paper picker 5 to put paper and reset before pressing paper. The moving stroke of the paper picker 5 is shortened, thereby reducing the time for taking and putting paper pieces and pressing paper, thereby improving the overall processing efficiency.

[0023] Specifically, the paper bins 6 include three, and the three paper bins 6 are equidistantly arranged on the top surface of the mounting frame 3. The right side of the bracket 4 is an open structure for the installation of the paper bins 6. The paper picker 5 includes a telescopic cylinder 12, a push plate 13 and three manipulators. The bracket 4 is provided with a plurality of guide rods 14, and the push plate 13 is slidably connected with the plurality of guide rods 14 through a plurality of guide sleeves. The telescopic cylinder 12 is fixed to the left side of the bracket 4, and the output end of the telescopic cylinder 12 is connected to the push plate 13. The three manipulators are arranged on the push plate 13 and are located in the same straight line corresponding to the three paper bins 6, wherein the manipulator includes a mounting rod 15 and a support plate 16. The support plate 16 is connected to the bottom of the push plate 13 through the mounting rod 15, and a plurality of paper suction discs 17 are provided on the side of the support plate 16 facing away from the mounting rod 15. Figures 1 to 5 As shown, the telescopic cylinder 12 drives the push plate 13 to move along the guide rod 14 toward the paper bin 6, and the manipulator on the push plate 13 moves to the position of the paper bin 6. The manipulator sucks a piece of paper located on the outside of the paper bin 6 through the suction disc 17. Then the telescopic cylinder 12 drives the paper piece to move to the top of the lower cardboard 8 through the manipulator so that the paper piece is aligned with the lower paper slot 9 of the lower cardboard 8. After the suction disc 17 sends the paper piece away, the cardboard can be inserted into the lower paper slot 9 and move to the position of the through slot 10 of the lower cardboard 8. Then the telescopic cylinder 12 drives the manipulator to continue taking paper.

[0024] Furthermore, the driver includes a driving motor 18 and three sprockets 19, the driving motor 18 is arranged on the left outer side of the mounting frame 3, and the output end of the driving motor 18 is provided with a driving wheel 20, the three sprockets 19 are respectively rotatably connected to the mounting frame 3 through a rotating shaft, and the three sprockets 19 and the driving wheel 20 are sleeved with a transmission chain 21, wherein the driver also includes two tensioning wheels 22, the two tensioning wheels 22 and the three sprockets 19 are staggered up and down and arranged on the left outer side of the mounting frame 3 and are against the transmission chain 21, the end of the rotating shaft away from the sprocket 19 is provided with a linkage tooth 23, the outer side of the lower mold 7 is sleeved with a gear ring 24, and the linkage tooth 23 is meshed with the gear ring 24, as shown 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 active wheel 20 to rotate, and the active 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] Furthermore, a mold core is provided in the lower mold 7, and a molding groove 25 with a diameter gradually decreasing toward the mold core is provided on the right side of the lower mold 7, and a plurality of strip slots 26 are provided in the molding groove 25, wherein the lower paperboard 8 includes three, and the three lower paperboards 8 are provided on the mounting frame 3 through a transverse plate, and the right side of the top 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 curved 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 degrees and fold the folded edge toward the paper cup.

[0026] Furthermore, the upper mold 11 includes three, a plurality of slide rods 27 are provided on the mounting frame 3, and 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 to the plurality of slide rods 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. The left end of the upper mold 11 is provided with a plurality of adsorption holes 33, and the upper mold 11 is provided with a vacuum tube connected to the plurality of adsorption holes 33. The right side of the mounting plate 30 is slidably connected with a spring seat 34, and 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. 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 provided 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 the connecting shaft. The servo motor 28 drives the rocker arm 31 to rotate through the transmission seat 29, and 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, thereby avoiding 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 functions 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 generates suction in the adsorption hole 33. The vacuum tube can be connected to an external vacuum generator (not shown in the figure), so that the upper mold 11 can suck the paper cup so that the upper mold 11 can remove the paper cup from 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 trough 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.
