Description

Technical Field

[0001] This utility model relates to the field of paper cup processing equipment technology, and in particular to an automated adaptive seam bonding cup-separating mechanism. Background Technology

[0002] Paper cup seam bonding technology is a manufacturing process. Its core process is to roll a pre-printed and die-cut rectangular paper blank into a conical cup body. Then, food-grade adhesive (such as hot melt adhesive) is applied to the overlapping edges of the paper blank using specialized equipment, and a certain amount of pressure and heat are applied to make the seam quickly cured and bonded, thereby forming a complete, leak-proof paper cup container with sufficient structural strength.

[0003] However, existing equipment often encounters the following problems during use: Before the seam gluing step, the stacked paper cups need to be separated one by one. Existing separating devices can only separate paper containers with a fixed opening. For example, stacked paper cups can only be separated, but cannot be seamlessly connected to paper bowls. Utility Model Content

[0004] The main objective of this invention is to provide an automated, adaptive seam-sealing cup-separating mechanism. This invention addresses the problem that, before seam-sealing paper cups, stacked paper cups need to be separated individually. Existing separating devices can only separate paper containers with a fixed diameter; for example, stacked paper cups can only be separated, not seamlessly joined to paper bowls, resulting in poor adaptability. This invention solves the problem of existing devices being incompatible with paper containers of different diameters by using a dynamically adjustable mechanical mechanism.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automated adaptive seam bonding cup-separating mechanism includes: A guide tube, wherein the guide tube is vertically arranged; A top base, located below the bottom end of the guide tube; The discharge port is located at the center of the top base, and the bottom end of the guide tube is connected to the discharge port. An adjusting plate is located below the top base and is movably connected to the bottom surface of the top base; An arc-shaped opening is provided, and a group of arc-shaped openings are equally distributed on the adjustment plate, and each arc-shaped opening penetrates the plate body of the adjustment plate; The aperture adaptation mechanism is provided, the number of which corresponds to the number of the arc-shaped openings, and each set of aperture adaptation mechanisms is located below the corresponding arc-shaped opening.

[0006] The caliber adaptation mechanism further includes: A sliding rod, the top end of which passes through the arc-shaped opening of the adjusting disc; A sliding plate, one end of which is sleeved onto the body of the sliding rod; An arc-shaped cut is made at the other end of the sliding plate; A rotating shaft, the top end of which is connected in a transmission manner to the end of a sliding plate with the arc-shaped cutout. A separator, which is cylindrical, is sleeved onto the shaft of the rotating shaft. External threads, which are distributed on the body of the separator.

[0007] Also includes: A fixing plate, which is located below the caliber adaptation mechanism; The guide rod is used to fix the fixed plate to the top base. A drive motor is externally mounted on the side wheel surface of the top base, and the output end of the drive motor faces downward. The main drive wheel is mounted on the output end of the drive motor; A drive belt, one end of which is sleeved on the main drive wheel, and the other end of which covers all the rotating shafts; The dial plate is provided on the side wheel surface of the adjustment disc.

[0008] The top surface of the fixed plate has a set of arc-shaped openings corresponding to the arc-shaped openings on the adjusting plate, and the bottom end of the sliding rod is embedded in the arc-shaped openings of the fixed plate.

[0009] The transmission belt is a high-toughness belt.

[0010] The longitudinal position of the fixed plate coincides with that of the adjusting plate. At least two guide rods are provided.

[0011] Compared with existing technologies, the advantages of this invention are as follows: This invention solves the problem of existing devices being incompatible with paper containers of different diameters by using a dynamically adjustable mechanical mechanism. Its core operation involves the operator turning an adjustment disc, which drives the internal arc-shaped opening to push the sliding rod and sliding plate, thereby simultaneously changing the effective diameter formed by all the rotating shafts and the separators fitted onto them, thus adapting to containers of different sizes such as paper cups or bowls. The entire process achieves a seamless transition from a fixed diameter to an adaptive diameter, demonstrating strong versatility. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figure 1-3 As shown, this utility model provides an automated adaptive joint bonding cup-separating mechanism, which includes a guide tube 1, a top base 2, a discharge port 3, an adjusting plate 4, an arc-shaped port 5, and a diameter adaptation mechanism 6.

[0020] The guide tube 1 is vertically positioned for guiding and organizing. Its core function is to keep stacked paper cups vertically aligned, ensuring they enter the separation area one after another in an orderly manner, preventing jamming caused by tilting. It serves as the "entry point" and "preparation area" of the entire workflow. The top base 2 is located below the bottom of the guide tube 1; it provides the structural and installation reference. The top base 2 acts as the "roof" of the mechanism, fixing the guide tube 1 and providing mounting points for components such as the drive motor 9. The guide rod 8 acts as a "column," firmly connecting the top base 2 to the fixing plate 7, forming a stable and rigid main frame that prevents overall deformation.

[0021] In this invention, the discharge port 3 is located at the center of the top base 2, and the bottom end of the guide tube 1 is connected to the discharge port 3. The adjusting plate 4 is located below the top base 2 and is movably connected to the bottom surface of the top base 2. A set of arc-shaped ports 5 are provided, and the set of arc-shaped ports 5 are equidistantly distributed on the adjusting plate 4, with each arc-shaped port 5 penetrating the plate body of the adjusting plate 4. When the adjusting plate 4 is manually rotated, the arc-shaped ports 5 are equivalent to a series of "cam grooves". These inclined groove walls push the sliding rods 61, forcing them to move along the groove trajectory, thereby converting the circular motion of the adjusting plate 4 into synchronous radial linear motion of all the sliding rods 61. The number of diameter adaptation mechanisms 6 corresponds to the number of arc-shaped ports 5, and each set of diameter adaptation mechanisms 6 is located below the corresponding arc-shaped port 5.

[0022] In this invention, the caliber adaptation mechanism 6 further includes a sliding rod 61 whose top end passes through the arc-shaped opening 5 of the adjusting disc 4; and a pivot for the direction of movement and connection. One end of a sliding plate 62 is fitted onto the sliding rod 61, and the other end is connected to a rotating shaft 64, forming a "connecting rod." It transmits the radial linear motion of the sliding rod 61 to the rotating shaft 64 in a 1:1 ratio, driving the rotating shaft 64 to move radially. The arc-shaped cutout 63 at its other end may be used to accommodate the rotating shaft 64 or related connecting parts, and to provide a certain amount of movement allowance during movement to avoid interference. One end of the sliding plate 62 is fitted onto the body of the sliding rod 61, and the arc-shaped cutout 63 is located at the other end of the sliding plate 62. The top end of the rotating shaft 64 is connected to the end of the sliding plate 62 with the arc-shaped cutout 63. The rotating shaft 64, as a transmission shaft for rotational movement, is driven by a transmission belt 11, transmitting rotational power to the separator 65 to perform a separation action.

[0023] In this invention, the separator 65 is cylindrical and is fitted onto the shaft 64. When multiple separators 65 are closed, their cylindrical shape and the surface of the external thread 66 together form a "virtual support surface" to support the cup's rim. The external thread 66 is distributed along the body of the separator 65. The external thread 66 is crucial for the separation action. When it rotates, the external thread 66 rubs and engages with the inner wall of the cup's rim, applying a circumferential torque. This torque causes a slight spiral deformation in the flexible cup's rim, thereby breaking its tight nesting with the upper cup and achieving the effect of "loosening" and falling naturally.

[0024] In this invention, the fixed disk 7 is located below the diameter adaptation mechanism 6; the top surface of the fixed disk 7 has a set of arc-shaped openings 5 ​​corresponding to the arc-shaped openings 5 ​​on the adjusting disk 4, the bottom end of the sliding rod 61 is embedded in the arc-shaped openings 5 ​​of the fixed disk 7, and the longitudinal position of the fixed disk 7 coincides with that of the adjusting disk 4. The fixed disk 7 is fixedly connected to the top base 2 through guide rods 8, at least two guide rods 8 are provided, the drive motor 9 is externally mounted on the side wheel surface of the top base 2, and the output end of the drive motor 9 faces downward, the main drive wheel 10 is mounted on the output end of the drive motor 9, one end of the transmission belt 11 is sleeved on the main drive wheel 10, and the other end of the transmission belt 11 covers all the rotating shafts 64; the transmission belt 11 is a high-tenacity belt. A manually driven lever 12 is provided on the side wheel surface of the adjusting disk 4.

[0025] In this invention, the transmission belt 11 is made of a high-toughness, high-elasticity material. Its core function is to solve the problem of dynamic changes in the geometric parameters of the transmission system caused by diameter adjustment. When the radial position of the separator 65 is changed by adjusting the disc 4, the center distance and relative spatial angle between each shaft 64 and the main drive wheel 10 change accordingly. The belt can automatically maintain an appropriate tension through its own elastic deformation, ensuring effective torque transmission under any diameter setting and preventing slippage or detachment. At the same time, its toughness ensures sufficient fatigue life even under complex working conditions with multiple driven pulleys and changing spatial paths. This achieves stable synchronous drive of multiple actuators with dynamically changing spatial positions from a single power source.

[0026] It should be noted that the automated adaptive seam bonding cup-separating mechanism designed in this utility model, when in use, involves manually moving the lever 12, which rotates the adjusting disc 4, causing the rotating shaft 64 to slide under the guidance of the arc-shaped opening 5. The rotating shaft 64 drives the sliding plate 62 to slide, and the sliding plate 62 slides towards the center of the discharge port 3. As each sliding plate 62 slides towards the center of the discharge port 3, the various separators 65 gradually retract inward, and the arc-shaped cut 63 retracts as a whole, thus limiting the diameter of the product passing through the discharge port 3. Conversely, it expands the diameter outward. The transmission belt 11, with its high toughness and elasticity, will adapt due to its own toughness. At this point, paper containers of the corresponding diameter, such as stacked paper cups, are placed into the guide tube 1. Due to gravity, the bottommost paper cup's rim comes into contact with the external thread 66. Finally, the drive motor 9 is started, and the motor's output drives the main drive wheel 10 to rotate, causing the transmission belt 11 to drive each rotating shaft 64 to rotate. The rotation of each rotating shaft 64 drives the adjusting part of the socket and its external thread 66 to rotate. The rotating external thread 66 will gradually generate torque with the rim of the bottommost paper cup. This rotational torque will gradually "loosen" the bottommost paper cup, causing it to undergo slight elastic deformation and twisting, thereby breaking its nesting tightness with the second paper cup above. After the bottommost paper cup is "loosened," its supporting state is destroyed. Under the action of gravity, it falls out from the gap between the separators 65 and is successfully separated and discharged through the arc-shaped opening 5 and discharge port 3 of the fixed plate 7. After the bottom paper cup is discharged, all the paper cups stacked above it move down one station under gravity, and the new bottom paper cup then falls onto the separator 65. The mechanism continues to operate, repeating the above steps to achieve single, continuous, and automated separation and discharge of paper cups.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
