Description

Technical Field

[0001] This utility model relates to the field of paper cup production technology, specifically to a paper cup anti-tear edge 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 shaped like cups. 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℃, even boiling water. Paper cups are characterized by safety, hygiene, lightness, and convenience, and are widely used in people's lives. They can be used in public places, restaurants, and eateries. They are disposable items. During the production and processing of paper cups, a rim forming device is used to rim the edges of the paper cups to prevent tearing during use and to reinforce them.

[0003] A search revealed a Chinese patent publication dated November 1, 2022, with publication number CN217704931U, describing a paper cup production anti-tear and edge-forming device. The device generally includes a worktable, a first support frame fixedly mounted on the top surface of the worktable, a lifting component at one end of the first support frame, a curling element fixedly mounted at the bottom end of the lifting component, a rotating disk movably mounted on the upper surface of the worktable, a plurality of paper cup fixing holes on the surface of the rotating disk, a second support frame located away from the rotating disk, an electric lifting rod fixedly connected to the lower surface of the second support frame, a detachable component at the lower end of the electric lifting rod, and a cooling and forming assembly at the lower end of the detachable component.

[0004] Although the aforementioned existing technical solution can cool the edge of the paper cup and reduce the probability of deformation, the cooling time for the edge is relatively short, resulting in poor cooling effect. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a paper cup anti-tear edge forming device, which solves the problem mentioned in the background technology of short cooling time for edge forming, resulting in poor cooling effect.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a paper cup anti-tear edge forming device, comprising a worktable and a rotating disk. The top of the rotating disk has multiple evenly distributed paper cup slots. The rotating disk is located above the worktable. The bottom of the rotating disk has a hollow slot. A motor is installed at the bottom of the worktable, and the output end of the motor passes through the worktable and connects to the inner upper side wall of the hollow slot. A first mounting frame and a second mounting frame are fixedly connected to the top of the worktable. An electric push rod is installed at the bottom of the first mounting frame, and one end of the electric push rod is connected to a mounting plate. A crimping device that mates with the paper cup slots is installed at the bottom of the mounting plate. An arc-shaped groove that mates with the multiple paper cup slots is fixedly connected to the bottom of the second mounting frame. An arc-shaped distributor is provided on the inner side wall of the arc-shaped groove, and multiple evenly distributed nozzles are provided on the inner side wall of the arc-shaped distributor. A cooling device is installed at the top of the second mounting frame, and a transmission pipe is provided on the cooling device. One end of the transmission pipe passes through the arc-shaped groove and connects to the arc-shaped distributor.

[0009] By adopting the above technical solution, paper cups are placed in the paper cup slot, and the electric push rod is activated to move the mounting plate and the edge-rolling device, causing the edge-rolling device to fold the edges of the paper cups. Then, the motor drives the rotating disk to rotate, and the rotating disk carries the paper cups into the arc-shaped slot. At this time, the edge-rolling device continues to fold the edges of other paper cups. During this time, the paper cups make short stops and move inside the arc-shaped slot. During this period, the refrigeration equipment continuously sprays cold air into the arc-shaped slot through the transmission pipe, arc-shaped distributor and nozzle, thereby continuously cooling the paper cups. This increases the cooling time for folding the edges while maintaining normal equipment operation, thereby improving the cooling effect.

[0010] Optionally, a rotating groove is provided on the lower inner sidewall of each of the multiple paper cup slots. A rotating gear is rotatably connected inside the rotating groove, and one end of the rotating gear penetrates into the interior of the empty slot. A plurality of evenly distributed connecting rods are fixedly connected to the top of the workbench, and a fixed gear that meshes with the multiple rotating gears is fixedly connected to the top of the multiple connecting rods.

[0011] By adopting the above technical solution, when the paper cup is placed in the paper cup slot, the bottom of the paper cup is placed on the rotating gear. When the motor drives the rotating disk to rotate, the rotating disk drives multiple rotating gears to rotate around the fixed gear, so that the rotating gear meshing with the fixed gear rotates on its own axis, thereby causing the rotating gear to drive the paper cup to rotate on its own axis. This allows the nozzle to spray cold air evenly on the edge of the slot, thereby achieving the purpose of improving the uniformity of cooling.

[0012] Optionally, both ends of the arc-shaped groove are provided with soft blinds.

[0013] By adopting the above technical solution, when the paper cup passes through the soft shielding curtain, the soft shielding curtain is pushed apart by the paper cup. The soft shielding curtain is used to shield both ends of the arc-shaped groove, reducing the escape speed of the cold air inside the arc-shaped groove, thereby achieving the purpose of improving the cooling effect.

[0014] Optionally, the bottom end of the rotating disk is rotatably connected to a plurality of evenly distributed ball bearings, the bottom ends of which are in close contact with the top end of the worktable.

[0015] By adopting the above technical solution, the ball bearings are used to reduce the friction between the rotating disk and the worktable, thereby improving the smoothness of equipment operation and reducing equipment wear.

[0016] Optionally, two cooperating limiting telescopic rods are provided between the mounting plate and the first mounting frame.

[0017] By adopting the above technical solution, the limiting telescopic rod is used to limit the mounting plate, preventing the mounting plate from shaking or tilting, thereby preventing the edge rolling equipment from shaking or tilting, and thus achieving the purpose of improving the stability of the equipment.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This paper cup production anti-tear edge forming device places the paper cup in a paper cup groove. Activating the electric push rod moves the mounting plate and the edge-rolling device, causing the edge-rolling device to roll the edge of the paper cup. Then, the motor drives a rotating disk, which carries the paper cup into an arc-shaped groove. Meanwhile, the edge-rolling device continues to roll other paper cups. During this time, the paper cups briefly stop and move within the arc-shaped groove. During this period, the refrigeration equipment continuously sprays cold air into the arc-shaped groove through a transmission pipe, an arc-shaped distributor, and nozzles, thus continuously cooling the paper cups. This increases the cooling time for the edge rolling while maintaining normal equipment operation, thereby improving the cooling effect. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-4 A paper cup anti-tear edge forming device includes a workbench 1 and a rotating disk 2. The top of the rotating disk 2 has multiple evenly distributed paper cup grooves 3. The rotating disk 2 is located above the workbench 1. The bottom of the rotating disk 2 has a hollow groove. A motor 4 is installed at the bottom of the workbench 1. The output end of the motor 4 passes through the workbench 1 and connects to the inner upper side wall of the hollow groove. A first mounting frame 5 and a second mounting frame 6 are fixedly connected to the top of the workbench 1. An electric push rod 7 is installed at the bottom of the first mounting frame 5. One end of the electric push rod 7 is connected to a mounting plate 8. A crimping device 9 that cooperates with the paper cup grooves 3 is installed at the bottom of the mounting plate 8. An arc-shaped groove 10 that cooperates with the multiple paper cup grooves 3 is fixedly connected to the bottom of the second mounting frame 6. An arc-shaped distributor 11 is provided on the inner side wall of the arc-shaped groove 10. Multiple evenly distributed nozzles 12 are provided on the inner side wall of the arc-shaped distributor 11. A cooling device 13 is installed at the top of the second mounting bracket 6. The cooling device 13 is equipped with a transmission pipe 14. One end of the transmission pipe 14 passes through the arc-shaped groove 10 and is connected to the arc-shaped distributor 11. The paper cup is placed in the paper cup groove 3. The electric push rod 7 is started to drive the mounting plate 8 and the edge-rolling device 9 to move, so that the edge-rolling device 9 rolls the edge of the paper cup. Then the motor 4 drives the rotating disk 2 to rotate. The rotating disk 2 carries the paper cup into the arc-shaped groove 10. At this time, the edge-rolling device 9 continues to roll the edge of other paper cups. The paper cups make short stops and move inside the arc-shaped groove 10. During this period, the cooling device 13 continuously sprays cold air into the arc-shaped groove 10 through the transmission pipe 14, the arc-shaped distributor 11 and the nozzle 12 to continuously cool the paper cup. This increases the cooling time of the edge rolling while keeping the equipment working normally, thereby improving the cooling effect.

[0029] Reference Figure 3 and Figure 4 Multiple paper cup slots 3 have rotating grooves on their inner lower side walls. Rotating gears 15 are rotatably connected inside the rotating grooves, with one end of each rotating gear 15 penetrating into the interior of the empty slot. Multiple evenly distributed connecting rods 16 are fixedly connected to the top of the workbench 1. Fixed gears 17, which mesh with multiple rotating gears 15, are fixedly connected to the top of each connecting rod 16. When a paper cup is placed in a paper cup slot 3, the bottom of the paper cup rests on the rotating gear 15. When the motor 4 drives the rotating disk 2 to rotate, the rotating disk 2 drives multiple rotating gears 15 to rotate around the fixed gear 17. This causes the rotating gears 15 meshing with the fixed gear 17 to rotate, thereby causing the paper cup to rotate. This allows the nozzle 12 to spray cold air evenly onto the edge of the slot, thus improving the uniformity of cooling.

[0030] Reference Figure 1 Both ends of the arc-shaped groove 10 are provided with soft shielding curtains 18. When the paper cup passes through the soft shielding curtains 18, the soft shielding curtains 18 are pushed apart by the paper cup. The soft shielding curtains 18 are used to shield both ends of the arc-shaped groove 10, reduce the escape speed of the cold air inside the arc-shaped groove 10, and thus achieve the purpose of improving the cooling effect.

[0031] Reference Figure 3 and Figure 4 The bottom end of the rotating disk 2 is rotatably connected with a number of evenly distributed balls 19. The bottom end of the balls 19 is in close contact with the top end of the worktable 1. The balls 19 are used to reduce the friction between the rotating disk 2 and the worktable 1, thereby improving the smoothness of equipment operation and reducing equipment wear.

[0032] Reference Figure 2 Two matching limiting telescopic rods 20 are provided between the mounting plate 8 and the first mounting frame 5. The limiting telescopic rods 20 are used to limit the mounting plate 8 to prevent the mounting plate 8 from shaking or tilting, thereby preventing the edge rolling equipment 9 from shaking or tilting, thus improving the stability of the equipment.

[0033] In summary, the working principle and process of this paper cup anti-tear edge forming device are as follows: First, the paper cup is placed in the paper cup slot 3. The electric push rod 7 is activated, driving the mounting plate 8 and the edge-rolling device 9 to move, causing the edge-rolling device 9 to fold the edge of the paper cup. Then, the motor 4 drives the rotating disk 2 to rotate, and the rotating disk 2 carries the paper cup into the arc-shaped slot 10. At this time, the edge-rolling device 9 continues to fold the edges of other paper cups. The paper cups briefly stop and move inside the arc-shaped slot 10. During this period, the cooling device 13 continuously sprays cold air into the arc-shaped slot 10 through the transmission pipe 14, the arc-shaped distributor 11, and the nozzle 12, thereby continuously cooling the paper cups. This increases the cooling time for edge folding while maintaining normal equipment operation, thus improving the cooling effect. When the paper cup is placed in the paper cup slot 3, the bottom of the paper cup rests on the rotating gear 15. When the motor 4 drives the rotating disk 2 to rotate, the rotating disk 15 rotates... The disc 2 drives multiple rotating gears 15 to rotate around the fixed gear 17, thereby causing the rotating gears 15 meshing with the fixed gear 17 to rotate on their own axis. This causes the rotating gears 15 to rotate the paper cup, allowing the nozzle 12 to spray cold air evenly onto the edge of the cup, thus improving the uniformity of cooling. When the paper cup passes through the soft shielding curtain 18, the soft shielding curtain 18 is pushed apart by the paper cup. The soft shielding curtain 18 is used to shield both ends of the arc-shaped groove 10, reducing the escape rate of cold air inside the arc-shaped groove 10, thereby improving the cooling effect. The ball bearing 19 is used to reduce the friction between the rotating disc 2 and the worktable 1, thereby improving the smoothness of equipment operation and reducing equipment wear. The limiting telescopic rod 20 is used to limit the mounting plate 8 to prevent the mounting plate 8 from shaking or tilting, thereby preventing the edge-rolling equipment 9 from shaking or tilting, thus improving the stability of the equipment.

[0034] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
