Description

Technical Field

[0001] This invention relates to the field of container dispensing device technology, and in particular to the clamping structure of a cup dispenser and its usage method. Background Technology

[0002] Disposable cups are extremely common in daily life, especially in public places, office areas, fast food restaurants, beverage vending machines, and household water dispensers. For easy storage and retrieval, multiple cups are often stacked in a nested manner into a cylindrical shape and placed inside a cup dispenser. When a user needs to retrieve a cup, the dispenser separates and drops the individual cups.

[0003] Currently, disposable cups are typically stored in stacked cup dispensers, which separate the individual cups when needed. However, existing cup dispensers have the following main shortcomings in practical use: due to differences in cup manufacturing precision or stacking tightness, multiple cups can easily stick together and fall simultaneously, a phenomenon known as "cup sticking." Therefore, it is necessary to provide a cup dispenser that can reliably separate cups one by one. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping structure for a cup dropper and its method of use, which enables the separation of cups one by one.

[0005] The technical solution of the present invention: The cup dropper's clamping structure includes a mounting housing, with fixed seats on both the left and right sides inside the mounting housing. The mounting housing has a channel for the cup to fall between the two fixed seats. The fixed seats are provided with upper and lower clamping jaws distributed vertically. The two upper clamping jaws move towards each other and insert into the joint of the two cups to clamp the upper cup, while the two lower clamping jaws move away from each other and away from the lower cup. When the user takes the cup, the lower cup is removed.

[0006] Furthermore, the left and right upper and lower grippers are driven to move by a drive assembly; both the upper and lower grippers penetrate the fixed base and are slidably connected to it; the drive assembly includes a drive motor fixed inside the mounting housing via a protective shell, the output shaft of the drive motor is located inside the protective shell and fixed with a first gear, the first gear meshing with a second gear, the second gear being fixed on a rotating shaft, and third gears being fixed at both ends of the rotating shaft, the third gears meshing with a first rack; the front end of the first rack has an inclined guide groove, the bottom of the inclined guide groove has a guide block, and the guide block is slidably connected to a first guide rod fixed inside the mounting housing; A first sliding shaft is slidably connected inside the inclined guide groove, and the first sliding shaft is fixedly connected to a lifting seat; the side of the lifting seat near the upper gripper is a first sliding surface, the upper end of the first sliding surface is a first inclined surface, the middle end is a vertical surface, and the lower end is a second inclined surface; The upper gripper is fixed with a first fixing frame on the side near the lifting seat. The side of the first fixing frame near the lifting seat contacts the first sliding surface via a first roller. The first fixing frame is reset by a first reset assembly. The lower gripper is fixed with a second fixing frame on the side near the lifting seat. The side of the second fixing frame near the lifting seat contacts the first sliding surface via a second roller. The second fixing frame is reset by a second reset assembly.

[0007] Furthermore, the lifting seat is slidably connected to a second guide rod fixed inside the mounting housing.

[0008] Furthermore, the first reset assembly includes a first guide shaft fixed at both ends of the first fixing frame, the first guide shaft penetrating the fixing seat and slidably connected to the fixing seat; the end of the first guide shaft is fixedly connected to the upper gripper; a first spring is sleeved on the first guide shaft, one end of the first spring is connected to the first fixing frame, and the other end is connected to the fixing seat.

[0009] Furthermore, the second reset assembly includes a second guide shaft fixed at both ends of the second fixed frame, the second guide shaft penetrating the fixed seat and slidably connected to the fixed seat; the end of the second guide shaft is fixedly connected to the lower gripper; a second spring is sleeved on the second guide shaft, one end of the second spring is connected to the second fixed frame, and the other end is connected to the fixed seat.

[0010] Furthermore, it also includes an auxiliary disengagement component; the auxiliary disengagement component includes a lever hinged to the side of the fixed seat near the cup, a fourth gear fixed on the lever, the upper end of the fourth gear meshing with a second rack on the movable seat, the movable seat penetrating the fixed seat and slidably connected to the fixed seat; two sliders are fixed on the movable seat near the lifting seat, the lifting seat has a third inclined surface that cooperates with the sliders; a third guide shaft slidably connected to the fixed seat is fixed on the slider, a third spring is sleeved on the third guide shaft, one end of the third spring is connected to the fixed seat, and the other end is connected to the slider.

[0011] The method for using the clamping structure of the cup dropper is as follows: Step 1: Drive the first gear to rotate by the drive motor, which in turn drives the second gear to rotate, which in turn drives the shaft to rotate, which in turn drives the first rack to move back and forth; Step 2: When the first rack moves forward, the first sliding shaft slides in the inclined guide groove, causing the lifting seat to move upward; Step 3: When the first roller slides to the vertical plane, the upper jaw moves towards the cup, so that the two upper jaws grip the cup above. When the second roller slides to the second inclined plane, the lower jaw moves away from the cup, so that the two lower jaws release their grip on the cup below. The user can then remove the cup below when taking it out. Step 4: When the first rack moves backward, the first sliding shaft slides in the inclined guide groove, causing the lifting seat to move downward. When the first roller slides to the first inclined plane, the upper jaw moves away from the cup, causing the two upper jaws to release their grip on the cup and let the cup fall. When the second roller slides to the vertical plane, the lower jaw moves closer to the cup, causing the two lower jaws to grip the cup.

[0012] Furthermore, it also includes step 5: when the lifting seat moves upward, the moving seat moves towards the cup, the second rack extends to clamp the cup, and at the same time the fourth gear rotates to drive the lever to drop down and release the clamp on the cup, while simultaneously moving the cup located below to separate the cup, thus realizing the automatic separation of the cup. At this time, the third spring is compressed and has elasticity. When the lifting seat moves downward, the elastic force of the third spring causes the moving seat to move away from the cup, the second rack retracts and releases the grip on the cup, and at the same time the fourth gear rotates to drive the lever to lift and grip the cup.

[0013] The beneficial effects of this invention are: The two upper jaws on the left and right move towards each other and insert into the joint of the two cups to hold the upper cup, while the two lower jaws on the left and right move away from the lower cup, allowing the user to remove the lower cup when taking it out.

[0014] In summary, this invention enables the separation of cups one by one. Attached Figure Description

[0017] The invention will now be further described with reference to the accompanying drawings.

[0018] like Figures 1-8 As shown, the present invention provides a first embodiment of the clamping structure of a cup dropper, including a mounting housing 1, wherein fixed seats 2 are fixed on both the left and right sides inside the mounting housing 1, and a channel 3 for the cup 100 to fall on the mounting housing 1 and located between the two fixed seats 2; the fixed seats 2 are provided with upper clamping claws 4 and lower clamping claws 5 distributed vertically, the two upper clamping claws 4 move towards each other and insert into the joint of the two cups 100 to clamp the upper cup 100, and the two lower clamping claws 5 move away from the lower cup 100, so that the user can take away the lower cup 100 when taking the cup.

[0019] The two upper grippers 4 and lower grippers 5 are driven to move by a drive assembly 6; both the upper grippers 4 and lower grippers 5 penetrate the fixed base 2 and are slidably connected to the fixed base 2; the drive assembly 6 includes a drive motor 62 fixed inside the mounting housing 1 via a protective shell 61, the output shaft of the drive motor 62 is located inside the protective shell 61 and a first gear 63 is fixed thereon, the first gear 63 meshes with a second gear 64, the second gear 64 is fixed on a rotating shaft 65, and a third gear 66 is fixed at both ends of the rotating shaft 65, the third gear 66 meshes with a first rack 67; the front end of the first rack 67 has an inclined guide groove 68, the bottom of the inclined guide groove 68 has a guide block 69, and the guide block 69 is slidably connected to a first guide rod 610 fixed inside the mounting housing 1; A first sliding shaft 611 is slidably connected inside the inclined guide groove 68. The first sliding shaft 611 is fixedly connected to a lifting seat 612. The side of the lifting seat 612 near the upper gripper 4 is a first sliding surface. The upper end of the first sliding surface is a first inclined surface 613, the middle end is a vertical surface 614, and the lower end is a second inclined surface 615. The upper gripper 4 is fixed with a first fixing frame 616 on the side near the lifting seat 612. The side of the first fixing frame 616 near the lifting seat 612 contacts the first sliding surface via the first roller 617. The first fixing frame 616 is reset by the first reset component. The lower gripper 5 is fixed with a second fixing frame 618 on the side near the lifting seat 612. The side of the second fixing frame 618 near the lifting seat 612 contacts the first sliding surface via the second roller 619. The second fixing frame 618 is reset by the second reset assembly. The first gear 63 is driven to rotate by the drive motor 62, which in turn drives the second gear 64 to rotate, which in turn drives the rotating shaft 65 to rotate, which in turn drives the first rack 67 to move back and forth. When the first rack 67 moves forward, the first sliding shaft 611 slides in the inclined guide groove 68, which causes the lifting seat 612 to move upward. When the first roller 617 slides to the vertical surface 614, the upper jaw 4 moves towards the cup 100, so that the two upper jaws 4 clamp the cup 100 above. When the second roller 619 slides to the second inclined surface 615, the lower jaw 5 moves away from the cup 100, so that the two lower jaws 5 release the clamp on the cup 100 below. When the user takes the cup, he or she can take the cup 100 below.

[0020] When the first rack 67 moves backward, the first sliding shaft 611 slides in the inclined guide groove 68, causing the lifting seat 612 to move downward. When the first roller 617 slides to the first inclined surface 613, the upper jaw 4 moves away from the cup 100, causing the two upper jaws 4 to release their grip on the cup 100, allowing the cup 100 to fall. When the second roller 619 slides to the vertical surface 614, the lower jaw 5 moves towards the cup 100, causing the two lower jaws 5 to grip the cup 100.

[0021] Based on the first embodiment, the present invention provides a second embodiment of the clamping structure of the cup dropper, wherein the lifting seat 612 is slidably connected to the second guide rod 620 fixed inside the mounting housing 1. This allows the second guide rod 620 to guide the lifting seat 612 as it rises and falls, ensuring stable lifting and lowering.

[0022] Based on any of the above embodiments, the present invention provides a third embodiment of the clamping structure of the cup dropper. The first reset component includes a first guide shaft 71 fixed at both ends of a first fixed frame 616. The first guide shaft 71 penetrates the fixed base 2 and is slidably connected to the fixed base 2. The end of the first guide shaft 71 is fixedly connected to the upper gripper 4. A first spring 72 is sleeved on the first guide shaft 71. One end of the first spring 72 is connected to the first fixed frame 616, and the other end is connected to the fixed base 2. When the first roller 617 slides to the vertical surface 614, the upper gripper 4 moves towards the cup 100. At this time, the first spring 72 is compressed and has elastic force. When the lifting seat 612 moves downward, due to the elastic force of the first spring 72, the upper gripper 4 moves away from the cup 100, thereby enabling the first roller 617 to contact the first inclined surface 613 and slide on the first inclined surface 613.

[0023] Based on any of the above embodiments, the present invention provides a fourth embodiment of the clamping structure of the cup dropper. The second reset component includes a second guide shaft 81 fixed at both ends of the second fixed frame 618. The second guide shaft 81 penetrates the fixed base 2 and is slidably connected to the fixed base 2. The end of the second guide shaft 81 is fixedly connected to the lower gripper 5. A second spring 82 is sleeved on the second guide shaft 81. One end of the second spring 82 is connected to the second fixed frame 618, and the other end is connected to the fixed base 2. When the second roller 619 slides to the vertical surface 614, the lower gripper 5 moves towards the cup 100. At this time, the second spring 82 is compressed and has elastic force. When the lifting seat 612 moves upward, due to the elastic force of the second spring 82, the lower gripper 5 moves away from the cup 100, thereby enabling the second roller 619 to contact the second inclined surface 615 and slide on the second inclined surface 615.

[0024] Based on any of the above embodiments, the present invention provides a fifth embodiment of the clamping structure of the cup dropper, which further includes an auxiliary disengagement component 9. The auxiliary disengagement component 9 can assist in disengaging the cup 100 located below, thereby achieving better separation of the cup. The auxiliary disengagement component 9 includes a lever 91 hinged to the side of the fixed base 2 near the cup 100. A fourth gear 92 is fixed on the lever 91. The upper end of the fourth gear 92 meshes with a second rack 93 on the movable base 94. The movable base 94 penetrates the fixed base 2 and is slidably connected to the fixed base 2. Two sliders 95 are fixed on one end of the movable base 94 near the lifting base 612. The lifting base 612 has a third inclined surface 96 that cooperates with the sliders 95. A third guide shaft 97 is fixed on the sliders 95 and slidably connected to the fixed base 2. A third spring 98 is sleeved on the third guide shaft 97. One end of the third spring 98 is connected to the fixed base 2, and the other end is connected to the slider 95.

[0025] When the lifting seat 612 moves upward, the moving seat 94 moves closer to the cup 100, the second rack 93 extends to clamp the cup 100, and at the same time the fourth gear 92 rotates to drive the lever 91 to lower and release the clamp on the cup 100. At the same time, the lower cup 100 is moved to separate the cup 100, realizing the automatic separation of the cup 100. At this time, the spring is compressed and has elastic force. When the lifting seat 612 moves downward, the elastic force of the spring causes the moving seat 94 to move away from the cup 100, the second rack 93 retracts to release the clamp on the cup 100, and at the same time the fourth gear 92 rotates to drive the lever 91 to lift and clamp the cup 100.

[0026] Based on any of the above embodiments of the cup dropper's clamping structure, the present invention provides a first embodiment of a method for using the cup dropper's clamping structure, the method being as follows: Step 1: Drive the first gear to rotate by the drive motor, which in turn drives the second gear to rotate, which in turn drives the shaft to rotate, which in turn drives the first rack to move back and forth; Step 2: When the first rack moves forward, the first sliding shaft slides in the inclined guide groove, causing the lifting seat to move upward; Step 3: When the first roller slides to the vertical plane, the upper jaw moves towards the cup, so that the two upper jaws grip the cup above. When the second roller slides to the second inclined plane, the lower jaw moves away from the cup, so that the two lower jaws release their grip on the cup below. The user can then remove the cup below when taking it out. Step 4: When the first rack moves backward, the first sliding shaft slides in the inclined guide groove, causing the lifting seat to move downward. When the first roller slides to the first inclined plane, the upper jaw moves away from the cup, causing the two upper jaws to release their grip on the cup and let the cup fall. When the second roller slides to the vertical plane, the lower jaw moves closer to the cup, causing the two lower jaws to grip the cup.

[0027] Based on the first embodiment of the method of using the clamping structure of the cup dropper, the present invention provides a second embodiment of the method of using the clamping structure of the cup dropper, which further includes step 5: when the lifting seat moves upward, the moving seat moves towards the cup, the second rack extends to clamp the cup, and at the same time the fourth gear rotates to drive the lever to drop down and release the clamping of the cup, and at the same time the lower cup is moved to separate the cup, so as to realize the automatic separation of the cup. At this time, the third spring is compressed and has elasticity. When the lifting seat moves downward, the elastic force of the third spring causes the moving seat to move away from the cup, the second rack retracts and releases the grip on the cup, and at the same time the fourth gear rotates to drive the lever to lift and grip the cup.
