Technical Field
[0001] This utility model relates to the field of paper cups, and in particular to a paper cup bonding and forming device. Background Technology
[0002] Paper cups are paper containers made by mechanically processing and bonding paper (white cardboard) made from chemical wood pulp. They are cup-shaped in appearance. Paper cups for frozen foods are coated with wax and can hold ice cream, jam, butter, etc. Paper cups for hot drinks are coated with plastic and can withstand temperatures above 90°C, even boiling water. Paper cups are characterized by safety, hygiene, lightness and convenience. They can be used in public places, restaurants and eateries, and are disposable items.
[0003] In modern life, paper cups are widely used in many scenarios such as catering, office work, and meetings due to their convenience and hygiene. With the continued growth in market demand for paper cups, production efficiency and quality have become key focuses for the industry.
[0004] In the paper cup production process, the bonding and forming process of paper cups mostly relies on manual operation or relatively simple mechanical equipment. Manual bonding is not only inefficient, but also prone to inconsistent bonding quality due to the variability of manual operation, resulting in problems such as weak bonding and uneven glue application. Simple mechanical bonding can mostly only bond and form individual paper cups, and cannot meet the production efficiency when bonding large batches of paper cups. Therefore, a paper cup bonding and forming device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a paper cup bonding and forming device, which aims to improve the existing technology. Manual bonding is not only inefficient, but also prone to inconsistent bonding quality due to the differences in manual operation, resulting in problems such as weak bonding and uneven glue application. Simple mechanical bonding can mostly only bond and form single paper cups, and cannot meet the production efficiency requirements when bonding large batches of paper cups.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A motor is fixedly installed at the bottom of the inner wall of the disc, a worm is fixedly installed at the output end of the motor, and a worm wheel is fixedly installed on the surface of the rotating rod, with the worm and the worm wheel meshing together.
[0012] As a further description of the above technical solution:
[0013] The heating assembly includes an electric heating wire, a heat-conducting plate is fixedly installed on the bottom of the inner wall of the heat insulation box, the bottom of the electric heating wire and the top of the heat-conducting plate are fixedly installed, a heat-conducting rod is fixedly installed on the bottom of the heat-conducting plate, a heat-conducting plate is provided at the bottom of the heat insulation box, the top of the heat-conducting plate and the bottom of the heat-conducting rod are fixedly installed, and the bottom of the heat-conducting plate and the top of the conical pressure block are fixedly installed.

[0018] As a further description of the above technical solution:
[0019] The top of the top plate has four through slots.
[0020] This utility model has the following beneficial effects:
[0021] In this invention, the rotating rod, large gear, small gear, and connecting rod work together to rotate the large gear, which in turn rotates the small gear, which in turn rotates the connecting rod, which in turn rotates the paper cup container, thus allowing the paper cup to be easily glued together.
[0022] In this invention, the electric heating wire, heat-conducting plate, heat-conducting rod, and heat-conducting plate work together to heat the electric heating wire. When the electric heating wire generates heat, it can transfer its temperature to the heat-conducting plate.

[0030] Reference Figure 1-4This utility model provides an embodiment of a paper cup bonding and forming device, including a base plate 1, a top plate 2 fixedly installed on the top of the base plate 1, a disc 3 fixedly installed on the top of the base plate 1, a paper cup container 4 disposed on the top of the disc 3, a rotating component 5 for rotating the paper cup container 4 disposed inside the disc 3, an electric push rod 6 fixedly installed on the bottom of the top plate 2, a heat insulation box 7 fixedly installed on the telescopic end of the electric push rod 6, a heating component 8 for heating the paper cup disposed inside the heat insulation box 7, and a conical pressing block 9 disposed at the bottom of the heat insulation box 7. First, the paper cup to be bonded and formed can be placed inside the paper cup container 4, and then the paper cup container 4 can be rotated by the rotating component 5. Then, the electric push rod 6 can be activated, and the telescopic end of the electric push rod 6 drives the heat insulation box 7 and the conical pressing block 9 to move to the bottom. Then, the conical pressing block 9 can be heated by the heating component 8. At this time, the heated conical pressing block 9 will enter the paper cup container 4, thereby gradually melting the glue on the paper cup, thus bonding and forming the paper cup.
[0031] Reference Figure 1-4 The rotating assembly 5 includes a rotating rod 51, the bottom of which is rotatably mounted to the bottom of the inner wall of the disc 3. A large gear 52 is fixedly mounted on the surface of the rotating rod 51. Five sets of small gears 53 are arranged inside the disc 3, meshing with the large gear 52. The top of the rotating rod 51 extends through to the top of the disc 3 and is rotatably mounted therewith. A connecting rod 54 is fixedly mounted on the top of the small gear 53. The bottom of the connecting rod 54 is rotatably mounted to the bottom of the inner wall of the disc 3, and the top of the connecting rod 54 extends through to the top of the disc 3 and is movably mounted therewith. The top of the rotating rod 51 is fixedly mounted to the bottom of the paper cup container 4. Through the mutual cooperation of the rotating rod 51, the large gear 52, the small gear 53, and the connecting rod 54, rotating the rotating rod 51 can drive the large gear 52 to rotate, which in turn drives the small gear 53 to rotate, and the small gear 53 in turn drives the connecting rod 54 to rotate. The connecting rod 54 rotates, causing the paper cup container 4 to rotate, thus facilitating the bonding of the paper cup. A motor 55 is fixedly installed at the bottom of the inner wall of the disc 3. A worm gear 56 is fixedly installed at the output end of the motor 55. A worm wheel 57 is fixedly installed on the surface of the rotating rod 51. The worm gear 56 and the worm wheel 57 mesh. Through the cooperation of the motor 55, the worm gear 56 and the worm wheel 57, the motor 55 can be started. The output end of the motor 55 drives the worm wheel 57 to rotate. The rotation of the worm wheel 57 drives the rotating rod 51 to rotate. At this time, under the action of the worm wheel 57 and the worm gear 56, the rotating rod 51 can rotate slowly, and the paper cup inside the paper cup container 4 can be prevented from being thrown out. A fixing block 10 is fixedly installed at the bottom of the inner wall of the disc 3. The right side of the fixing block 10 and the left end of the worm gear 56 are rotatably installed. The fixing block 10 can limit the worm gear 56 and prevent the worm gear 56 from shaking when rotating.
[0032] Reference Figure 1-4The heating assembly 8 includes an electric heating wire 81. A heat-conducting plate 82 is fixedly installed on the bottom of the inner wall of the heat insulation box 7. The bottom of the electric heating wire 81 and the top of the heat-conducting plate 82 are fixedly installed. A heat-conducting rod 83 is fixedly installed on the bottom of the heat-conducting plate 82. A heat-conducting disk 84 is provided at the bottom of the heat insulation box 7. The top of the heat-conducting disk 84 and the bottom of the heat-conducting rod 83 are fixedly installed. The bottom of the heat-conducting disk 84 and the top of the conical pressure block 9 are fixedly installed. Through the cooperation of the electric heating wire 81, the heat-conducting plate 82, the heat-conducting rod 83 and the heat-conducting disk 84, the electric heating wire 81 can be heated. When the electric heating wire 81 generates heat, it can transfer its temperature to the heat-conducting plate 82, and the heat-conducting plate 82 can transfer its temperature to the heat-conducting rod 83. The heat-conducting rod 83 then transfers heat to the heat-conducting plate 84, thereby heating the conical pressing block 9. When the conical pressing block 9 enters the paper cup container 4, it can gradually melt the glue on the paper cup, thus bonding the paper cup into shape. Support legs 11 are fixedly installed at the four corners of the bottom of the base plate 1, and anti-slip pads 12 are fixedly installed at the bottom of the support legs 11. Through the cooperation of the support legs 11 and the anti-slip pads 12, the base plate 1 can be supported, and the anti-slip pads 12 can prevent the base plate 1 from shaking. The top plate 2 has four through slots 13 on its top. The through slots 13 can reduce the weight of the top plate 2, thereby preventing the top plate 2 from being too heavy and breaking.
[0033] Working principle: First, the paper cups to be bonded and formed can be placed inside the paper cup container 4. Then, the electric heating wire 81 can be energized and heated. When the electric heating wire 81 generates heat, it can transfer its temperature to the heat-conducting plate 82. The heat-conducting plate 82 can transfer its temperature to the heat-conducting rod 83, and the heat-conducting rod 83 can then transfer the heat to the heat-conducting plate 84, thereby heating the conical pressing block 9. When the conical pressing block 9 reaches a suitable temperature, the electric push rod 6 can be activated. The telescopic end of the electric push rod 6 drives the heat insulation box 7, the heat-conducting plate 84, and the conical pressing block 9 to move to the bottom. The bottom movement gradually enters the paper cup container 4. When the conical pressing block 9 enters the paper cup container 4, it can gradually melt the glue on the paper cup. Then, the motor 55 can be started. The output end of the motor 55 drives the worm gear 57 to rotate. The rotation of the worm gear 57 can slowly drive the rotating rod 51 to rotate. The rotation of the rotating rod 51 drives the large gear 52 to rotate. The rotation of the large gear 52 drives the small gear 53 to rotate. The rotation of the small gear 53 drives the connecting rod 54 to rotate. The rotation of the connecting rod 54 drives the paper cup container 4 to rotate, thereby bonding, pressing and squeezing the paper cup inside the paper cup container 4 into shape.
