[0056] In the embodiments described below, the positional relationships include: up, down, left, and right. Unless otherwise specified, they are all based on the direction shown by the components in the diagram.

[0057] Please see Figure 1 and Figure 2 The illustration depicts an automatic double-walled cup production equipment, comprising a worktable 100 having a fixed base 11 disposed on a base 10, an annular track 15 disposed on the fixed base 11, and a plurality of cup holders 16 disposed along the annular track 15. The annular track 15 is rotated in a clockwise direction, defining a cup inlet side and a pressing side, and is respectively located on two opposite long sides of the annular track 15.

[0058] A first cup-feeding device 20 and a second cup-feeding device 30 are spaced apart on the cup-feeding side, and a pressing device 40 and a finished product transport device 50 are disposed on the pressing side. The position of the first cup-feeding device 20 is defined as a working start position, and the position of the finished product transport device 50 is defined as a working end position. The cup holder 16 rotates sequentially from the working start position (the position of the first cup-feeding device 20) to the second cup-feeding device 30, the pressing device 40 and the finished product transport device 50 (i.e., the working end position) to form a work cycle.

[0059] The first cup-feeding device 20 is used to feed the first cup 25 into the cup holder 16 on the annular track 15, and the second cup-feeding device 30 is used to feed the second cup 35 into the first cup 25. In the embodiments of this application, the first cup 25 is a paper cup and the second cup 35 is a plastic cup.

[0060] Please see Figure 3 The first cup body insertion device 20 includes a cup holder 21, a supplementary holder 29, and a plurality of cup-lowering screws 23. The supplementary holder 29 is disposed on the upper side of the cup holder 21 (i.e., the side relatively far away from the cup holder 16), and the plurality of cup-lowering screws 23 are disposed on the lower side of the cup holder 21 (i.e., the side relatively close to the cup holder 16). The cup holder 21 has a plurality of cup-containing structures, each of which has an opening corresponding to the plurality of cup holders 16, and each of which is used to accommodate one or more first cup bodies 25.

[0061] The plurality of cup-lowering screws 23 are arranged in groups of four, and each cup-lowering screw 23 has four threads to clamp the periphery of the cup opening of the first cup body 25, so that one of the plurality of first cup bodies 25 controlled by the cup-containing structure falls into the cup holder 16, and the cup holder 21 drops one first cup body 25 onto the cup holder 16 at a time.

[0062] The supplementary rack 29 is rectangular and has multiple cup slots arranged along the long side of the supplementary rack 29 to form a front cup array and a rear cup array. Each cup slot in the front cup array has an opening corresponding to the multiple cup structures. Each cup slot is used to accommodate multiple first cups 25. When the first cup 25 of the aforementioned cup structure falls onto the cup holder 16, the first cup 25 in the cup slot automatically falls to replenish the cup structure.

[0063] To further explain, in this embodiment of the application, a cup baffle 27 is also provided between the rear cup array and the cup holder 21. The cup baffle 27 closes multiple openings of the cup slots of the rear cup array, and the first cup 25 is added to the rear cup array by a supplementary machine (not shown in the figure).

[0064] In this embodiment, the replenishment rack 29 is rotatable, and the cup baffle 27 is adjustable and movable between the front row cup array and the rear row cup array. After all the first cups 25 of the front row cup array fall onto the cup holder, the replenishment rack 29 is rotated by a robotic arm (not shown in the figure), so that the front row cup array before rotation forms the rear row cup array after the replenishment rack rotates, and the rear row cup array before rotation forms the front row cup array. After rotation and positioning, the cup baffle 27 moves from the position of the front row cup array to the rear row cup array, so that the first cups 25 of the front row cup array can fall into the cup holder 21, and closes the multiple openings of the cup slots of the rear row cup array, so as to replenish the first cups 25.

[0065] Please see Figure 4 The second cup holder 30 includes a second cup holder 31, a second supplementary holder 39, and a plurality of cup-lowering screws 33. The second supplementary holder 39 is disposed on the upper side of the second cup holder 31 (i.e., the side relatively far away from the cup holder 16), and the plurality of cup-lowering screws 33 are disposed on the lower side of the second cup holder 31 (i.e., the side relatively close to the cup holder 16). The second cup holder 31 has a plurality of second cup-containing structures, each of which has an opening corresponding to the plurality of cup holders, and each of which is used to accommodate one or more second cup bodies 35.

[0066] The plurality of cup-lowering screws 33 are arranged in groups of four, and each cup-lowering screw 33 has four threads to clamp the periphery of the cup opening of the second cup body 35, so that one of the plurality of second cup bodies 35 controlled by the second cup structure falls onto the cup holder 16, and the second cup holder 31 drops one second cup body 35 onto the cup holder 16 at a time.

[0067] The second replenishment rack 39 is rectangular and has multiple second cup slots arranged along the long side of the second replenishment rack 39 to form a front cup array and a rear cup array. Each second cup slot in the front cup array has an opening corresponding to the multiple second cup structures. Each second cup slot is used to accommodate multiple second cups 35. When the second cups 35 of the aforementioned second cup structures fall onto the cup holder 16, the second cups 35 in the second cup slots automatically fall to replenish the second cup structures.

[0068] To further explain, in this embodiment of the application, a second cup baffle 37 is disposed between the rear cup array and the second cup holder 31. The second cup baffle 37 closes the multiple openings of the multiple second cup slots of the rear cup array, and the second cup body 35 is added to the rear cup array by a supplementary machine (not shown in the figure).

[0069] In this embodiment, the second replenishment rack 39 is rotatable, and the second cup baffle 37 is adjustable and movable between the front cup array and the rear cup array. After all the second cups 35 of the front cup array fall onto the cup holder, the second replenishment rack 39 is rotated by a robotic arm (not shown in the figure), so that the front cup array before rotation forms the rear cup array after the second replenishment rack 39 rotates, and the rear cup array before rotation forms the front cup array. After rotation and positioning, the second cup baffle 37 moves from the position of the front cup array to the rear cup array, so that the second cups 35 of the front cup array can fall into the second cup holder 31, and close the multiple openings of the second cup slot of the rear cup array, so as to replenish the second cups 35.

[0070] In addition, the second cup body insertion device 30 also has two pressure strips 38 respectively disposed on the two long sides of the second cup holder 31 located on the two sides of the plurality of cup lowering screws 33. In the embodiments of this application, the second cup body 35 is a lightweight plastic cup. The two pressure strips 38 apply pressure to the plastic cup to position the plastic cup and ensure that the plastic cup falls accurately into the first cup body 25 located on the cup holder.

[0071] Please see Figure 5 , Figure 6A and Figure 6BThe pressing device 40 is used to press the first cup body 25 and the second cup body 35. The pressing device 40 includes a base 41 disposed on the base 10, a slide rail 42 disposed on the base 41, and a power device disposed on the base 41 to drive a stand 43 to move along the slide rail 42. The power device is a power motor 471 that drives a power belt 472 to rotate, so that the stand 43 moves linearly along the slide rail 42. An upper mold plate 431 and a lower mold plate 432 are disposed parallel to one side of the stand 43. The upper mold plate 431 is disposed above the cup holder 16, and the lower mold plate 432 is disposed below the cup holder 16. A plurality of upper pressing units 44a are disposed on the upper mold plate 431, and a plurality of lower pressing units 44b are disposed on the lower mold plate 432.

[0072] To further explain, a drive module 46 is connected to the lower mold base plate 432. The drive module 46 consists of a motor 461 that drives a ball screw 462. The drive module 46 causes the lower mold base plate 432 to move up and down in a vertical direction, thereby pressing the lower die unit 44b against the upper die unit 44a (see [link]). Figure 6B In this embodiment, the upper molding unit 44a and the lower molding unit 44b are each provided with an electrical component (not shown in the figure). When the upper molding unit 44a and the lower molding unit 44b are pressed together, in addition to pressing the first cup body 25 and the cup body 35 together, in this embodiment, the second cup body 35 is a plastic cup. The electrical component conducts electricity and generates heat to soften the cup mouth of the plastic cup, strengthening the tightness between the cup mouth of the second cup body 35 and the cup mouth of the first cup body 25, so that the first cup body 25 and the second cup body 35 on the cup holder 16 are pressed together to form a double-layer cup 70 (see [reference]). Figure 7 The energizing component heats the rims of the first cup body 25 and the second cup body 35 to between 95°C and 150°C, with a preferred embodiment heating the rims to 100°C. After the first cup body 25 and the second cup body 35 are pressed together, the inner surface of the first cup body 25 curls outward and covers the rim of the second cup body 35, allowing the user to drink directly from the first cup body 25.

[0073] Please see Figure 8 , Figure 9A and Figure 9BThe finished product transport device 50 is used to output the double-layer cup 70 to the packaging area (not shown in the figure). The finished product transport device 50 includes a cup dispensing guide plate 51 disposed below the aforementioned cup holder 16. The cup dispensing guide plate 51 forms an angle with the cup holder 16 (i.e., the cup dispensing guide plate 51 is inclined relative to the cup holder 16). When the cup holder 16 with the double-layer cup 70 rotates to the finished product transport device 50, the double-layer cup 70 on the cup holder 16 contacts the cup dispensing guide plate 51 and leaves the cup holder 16. An air blowing unit 52 is disposed on the workbench 100 and has multiple air outlets 52a facing a conveying unit. When the aforementioned double-layer cup 70 leaves the cup holder, the air blowing unit 52 blows the double-layer cup 70 onto the conveyor belt 55 of the conveying unit.

[0074] To further explain, the conveyor belt 55 has a first guide plate 56 on the side closer to the cup holder 16 and a second guide plate 57 on the side farther away from the cup holder 16. The height of the second guide plate 57 is greater than the height of the first guide plate 56. When the air blowing unit 52 blows the double-layer cup 70 to the conveyor unit, the first guide plate 56 ensures that the double-layer cup 70 falls accurately onto the conveyor belt 55. The higher height of the second guide plate 57 is to prevent the air blowing unit 52 from blowing the double-layer cup 70 away from the conveyor belt 55, thus forming a retaining wall.

[0075] Please see Figure 10 This application also provides an automated method for producing double-walled cups, comprising the following steps:

[0076] a. Multiple first cups 25 are placed into multiple cup holders 16 on a circular track 15 via the first cup inlet device 20;

[0077] b. Multiple second cups 35 are placed into the first cup 25 using the second cup inlet device 30;

[0078] c. A double-walled cup 70 is formed by pressing the first cup body 25 and the second cup body 35 together using a pressing device 40; and

[0079] d. The double-walled cup 70 is output via a finished product transport device 50.

[0080] In this embodiment, the pressing device 40 can perform continuous pressing or batch pressing. During continuous pressing, the pressing device 40 drives the stand 43 to move linearly along the pressing side of the annular track 15 via the power device. That is, when the annular track 15 continues to rotate clockwise, the stand 43 moves linearly simultaneously. After the stand 43 moves from one end of the slide rail 42 to the other end, the pressing device 40 also simultaneously completes the aforementioned process of pressing the first cup 25 against the first... The pressing operation of two cups 35 to form a double cup 70 is carried out when the stand 43 is located at one end of the slide rail 42. The lower pressing unit 44b moves upward and presses with the upper pressing unit 44a. During the movement of the stand 43, the first cup 25 and the second cup 35 are heated to form a double cup 70. When the stand 43 moves to the other end of the slide rail 42, the lower pressing unit 44b moves downward and separates from the upper pressing unit 44a. After separation, the stand 43 resets along the slide rail 42 to carry out the next pressing operation.

[0081] During batch pressing operations, the pressing device 40 does not move in a straight line along the pressing side, but instead fixes the stand 43 at one end of the slide rail 42. When the cup holder 16 with the first cup body 25 and the second cup body 35 moves to the pressing device 40, the annular track 15 stops rotating. After the pressing device 40 completes the aforementioned pressing operation to form the double-layer cup 70, the annular track 15 will resume rotation and transfer the double-layer cup 70 to the finished product transport device 50.

[0082] The embodiments and / or implementation methods described above are merely preferred embodiments and / or implementation methods for implementing the technology of this application, and are not intended to limit the implementation methods of the technology of this application in any way. Any person skilled in the art may make some modifications or alterations to other equivalent embodiments without departing from the scope of the technical means disclosed in this application, but these should still be regarded as the technology or embodiments that are substantially the same as those of this application.
