Description

Technical Field

[0001] This invention relates to an improvement of paper cup forming equipment, and more particularly to an improvement of a high-speed paper cup bonding device. Background Technology

[0002] With the rapid development of the catering, coffee, and tea service industries, the market demand for double-layer paper cups, which combine heat insulation and aesthetics, continues to rise. Currently, the mainstream production mode for double-layer paper cups is to prepare them separately and then assemble them: first, the inner layer paper cup is made using an inner cup machine, and the outer layer paper cup is made using an outer cup machine. Then, the two types of paper cups are transferred to an independent cup-bonding device to complete the bonding process. This production model suffers from several industry pain points: 1. High equipment and space costs: Multiple machines, including inner cup machines, outer cup machines, and cup-attaching machines, are required, resulting in high equipment procurement costs and significant workshop space for equipment placement and semi-finished product transfer. 2. High labor and management costs: Multiple machines require multiple operators, and dedicated personnel are needed for the transfer and connection of semi-finished products, increasing labor costs and management complexity. 3. Low production efficiency: Transfer waiting time exists between processes, making it difficult to synchronize the rhythm of equipment and slowing down the overall production pace, which cannot meet the needs of large-scale mass production. 4. Poor product quality stability: The glue spraying process in existing cup-attaching equipment is mostly fixed, resulting in uneven glue application and insecure positioning of the inner cup on the cup mold, easily leading to problems such as misalignment and delamination, resulting in a high defect rate. In addition, semi-finished products are prone to bumps and deformation during transfer, further affecting product quality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a high-speed paper cup sticking device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The high-speed paper cup pasting device includes a frame, characterized in that: a vertical main wheel is rotatably provided on the frame, and a plurality of cup molds are arranged around the outer circumference of the main wheel. Each cup mold includes a shaft and a mold body disposed at the outer end of the shaft. The inner end of the shaft is rotatably connected to the main wheel. A cup feeding mechanism, a first cup pressing structure, a glue spraying mechanism, and a cup collecting mechanism are sequentially connected along the path of the cup mold as the main wheel rotates. The cup feeding mechanism and the cup collecting mechanism are located above and below the main wheel, respectively. The glue spraying mechanism is equipped with a second cup pressing structure, and the cup collecting mechanism is equipped with a third cup pressing structure.

[0005] The cup feeding mechanism includes a cup holder for placing the inner cup of the paper cup, the upper end of the cup holder is connected to the inner cup machine, and the lower end of the cup holder is provided with a spiral cup feeding structure.

[0006] The spiral cup structure includes four or more threaded guide posts that rotate relative to each other, and the space enclosed by the threaded guide posts is adapted to the size of the cup opening inside the paper cup.

[0007] The first cup pressing structure includes a first cup pressing frame, on which a first pressing plate is provided to extend and retract toward the cup mold.

[0008] The glue spraying mechanism includes a glue sprayer and a drive wheel that drives the cup mold to rotate. The nozzle of the glue sprayer corresponds to the position of the cup surface of the cup mold, and the drive wheel is driven by the shaft.

[0009] A glue hopper is located below the glue sprayer.

[0010] The second cup pressing structure includes a second cup pressing frame fixed at the glue spraying mechanism. The second cup pressing frame is provided with a second pressing plate that extends and retracts toward the cup mold, and the second pressing plate is rotatable.

[0011] The cup collecting mechanism includes a cup collecting tray, a cup collecting rod, and a pneumatic cup dispensing pipe. The cup collecting tray is rotatable and has several cup collecting openings. The cup collecting openings are connected in sequence to the paper cup outer cup machine, the cup mold, and the pneumatic cup dispensing pipe along the path of the cup collecting tray's rotation. The cup collecting rod can be raised and lowered through the cup collecting openings and the outer cup to pick up the inner cup from the cup mold and transfer it to the outer cup on the cup collecting opening.

[0012] The cup-collecting rod includes a rod body and a pneumatic suction cup disposed at the upper end of the rod body, and the rod body is disposed on a lifting base.

[0013] The third cup pressing structure includes a third cup pressing frame disposed above a cup collecting opening after the cup collecting rod. A third pressing plate that extends and retracts toward the corresponding cup collecting opening is slidably connected to the third cup collecting frame. A top plate that can be elastically extended and retracted is provided below the cup collecting plate, and the top plate is opposite to the third pressing plate.

[0014] The beneficial effects of this invention are as follows: The improved high-speed paper cup pasting device adopts a vertical main disc structure, which reduces the horizontal space occupied compared to traditional horizontal pasting equipment. At the same time, the paper cup inner cup machine, paper cup outer cup machine, and pasting process are integrated into the same frame, eliminating the need for multiple independent machines, reducing equipment procurement costs, and improving workshop space utilization. The entire process is automated and continuous, requiring only 1-2 operators to monitor the equipment and replenish raw materials. There is no need for dedicated personnel to handle semi-finished product transfer and multiple equipment monitoring, reducing labor costs and significantly decreasing management complexity. In addition, during the glue spraying process, the drive wheel drives the shaft of the cup mold, thereby causing the cup mold to rotate. This facilitates the glue sprayer to spray glue in a coil pattern onto the inner cup of the cup mold, resulting in more even glue application on the inner cup surface and better adhesion when combined with the outer cup, improving product quality and avoiding subsequent rework of defective products.

[0020] The accompanying drawings illustrate the structure of the present invention, and further details will be described below in conjunction with the drawings. In this embodiment, see the attached drawings. Figure 1-4 The high-speed paper cup applicator includes a frame 1, on which a vertical main wheel 2 is rotatably mounted. Preferably, the main wheel 2 is driven by a motor. Several cup molds 3 are arranged around the outer circumference of the main wheel 2. Each cup mold 3 includes a shaft and a mold body located at the outer end of the shaft. The inner end of the shaft is rotatably connected to the main wheel 2. Along the path of the cup mold 3 as the main wheel 2 rotates, a cup-up mechanism 4, a first cup-pressing structure 5, a glue-spraying mechanism 6, and a cup-collecting mechanism 7 are sequentially connected. The cup-up mechanism 4 and the cup-collecting mechanism 7 are located above and below the main wheel 2, respectively. The glue-spraying mechanism 6 is equipped with a second cup-pressing structure 8, and the cup-collecting mechanism 7 is equipped with a third cup-pressing structure 9.

[0021] As a further improved specific implementation, the cup feeding mechanism 4 includes a cup holder 41 for placing paper cup inner cups. The upper end of the cup holder 41 is connected to a paper cup inner cup machine. The inner cups produced by the paper cup inner cup machine are conveyed to the cup holder 41 through a pipe and stacked inside. The lower end of the cup holder 41 is provided with a spiral cup feeding structure 42 for dispensing cups.

[0022] As a further improved specific implementation, the spiral cup-dispensing structure 42 includes four or more threaded guide posts, which rotate relative to each other. It is preferably driven by a synchronous belt, and the space enclosed by the threaded guide posts is adapted to the size of the cup opening inside the paper cup. With the cooperation of the threaded guide posts, accurate cup dispensing is achieved.

[0023] As a further improved specific implementation, the first cup pressing structure 5 includes a first cup pressing frame 51, on which a first pressing plate 52 is provided to extend and retract toward the cup mold 3. Preferably, the first pressing plate 52 is driven to extend and retract by a cylinder to press the inner cup tightly onto the cup mold 3.

[0024] As a further improved embodiment, the glue spraying mechanism 6 includes a glue sprayer 61 and a drive wheel 62 that drives the cup mold 3 to rotate. The nozzle of the glue sprayer 61 corresponds to the cup surface of the cup mold 3. The drive wheel 62 is driven by the shaft, thereby driving the cup mold to rotate. This facilitates the glue sprayer to spray glue in a coil pattern onto the inner cup of the cup mold, making the glue sprayed more evenly on the inner cup surface. After being combined with the outer cup, the glue can be better bonded, improving product quality and avoiding subsequent rework of defective products. Preferably, the drive wheel 62 is a glue wheel that contacts the shaft and is driven by a motor.

[0025] As a further improved embodiment, a glue hopper 63 is provided below the glue sprayer 61 to catch the glue dripping from the glue sprayer 61.

[0026] As a further improved specific implementation, the second cup pressing structure 8 includes a second cup pressing frame 81 fixed at the glue spraying mechanism 6. The second cup pressing frame 81 is provided with a second pressing plate 82 that extends and retracts toward the cup mold 3. The second pressing plate 82 is rotatably set. Preferably, the second pressing plate 82 is driven to extend and retract by a cylinder to press the inner cup on the cup mold 3 to ensure stable glue spraying. At the same time, it can rotate with the cup to avoid the inner cup of the paper cup from shifting due to rotation.

[0027] As a further improved specific implementation, the cup collecting mechanism 7 includes a cup collecting tray 71, a cup collecting rod 72, and a pneumatic cup dispensing pipe. The cup collecting tray 71 is rotatably set. Preferably, the cup collecting tray 71 is driven by a motor, and a plurality of cup collecting ports 73 are provided around the cup collecting tray 71. The cup collecting ports 73 are connected in sequence to the paper cup outer cup machine, the cup mold 3, and the pneumatic cup dispensing pipe along the path of the cup collecting tray 71 as it rotates. The cup collecting rod 72 can be raised and lowered through the cup collecting ports 73 and the outer cup to pick up the inner cup from the cup mold 3 and transfer it to the outer cup on the cup collecting port 73.

[0028] As a further improved specific implementation, the cup collecting rod 72 includes a rod body and a pneumatic suction cup disposed at the upper end of the rod body, and the rod body is disposed on the lifting seat.

[0029] As a further improved specific implementation, the third cup pressing structure 9 includes a third cup pressing frame 91 disposed above a cup receiving opening 73 after the cup receiving rod 72. A third pressing plate 92 that extends and retracts toward the corresponding cup receiving opening 73 is slidably connected to the third cup receiving frame 91. Preferably, the third pressing plate 92 is driven to extend and retract by a cylinder to press the inner cup tightly into the outer cup, so that the two are tightly bonded. A top plate 93 that can be elastically extended and retracted is provided below the cup receiving plate 71. The top plate 93 is opposite to the third pressing plate 92. A spring is connected below the top plate 93. The top plate 93 is used to support the bottom of the outer cup to cooperate with the third pressing plate 92.

[0030] The working principle of this invention is as follows: during actual operation, the inner cups of the paper cups produced by the inner cup machine accumulate on the cup holder 41 and fall onto the cup mold 3 through the spiral cup-dropping structure 42. The cup mold 3 rotates with the main wheel 2 and is pressed by the first cup-pressing structure 5 in sequence. Then, the glue spraying mechanism 6 drives the inner cup to rotate and sprays glue on the surface of the inner cup. At the same time, the second cup-pressing structure 8 presses the inner cup while spraying glue. Meanwhile, the cup receiving plate 71 receives the outer cups of the paper cups produced by the outer cup machine at the cup receiving port 73 on the side away from the main wheel 2 and transfers them to the bottom of the corresponding cup mold 3. The cup receiving rod 72 passes through the cup receiving port and the outer cup to suck down the inner cup on the corresponding upper cup mold 3. The inner cup and the outer cup are combined and then leveled by the third cup-pressing structure 9 before being sent out for packaging by the pneumatic cup-out pipe.

[0031] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
