[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1 As shown, a paper cup bundling device for paper cup production includes a conveyor belt 1, a clamping device 2 is provided at one end of the conveyor belt 1 away from each other, a bundling assembly 3 is installed in the middle of the clamping device 2, a support frame 6 is fixedly connected to the lower front side of the clamping device 2, a clamping mechanical arm 5 is fixedly connected to the middle of the upper end of the support frame 6, and a roller device 4 is fixedly connected to the right side of the clamping device 2.

[0029] This device is mainly used for bundling paper cups.

[0030] The conveyor belt 1 in this device is an external conveyor belt 1, which can be connected to the conveyor belt on the paper cup production line, so that the device and the paper cup production line are integrated.

[0031] In the above description, before implementing the present device, a collecting frame can be placed in front of the conveyor belt 1 to collect the bundled paper cups.

[0032] In the above, the paper cups packed in the packaging bag are placed on the conveyor belt 1, and the conveyor belt 1 is started to continue transporting, and the packaged paper cups are transported to the bottom of the strapping component 3. When the paper cups are transported to the bottom of the strapping component 3, the conveyor belt 1 stops moving, and then the clamping device 2 is started to start descending. The clamping device 2 will clamp the paper cup when it descends to fix the paper cup. When the clamping device 2 moves to the position where it needs to be strapped, it stops moving, and then the clamping robot arm 5 moves to grab the packaging bag. After grabbing it, the clamping robot arm 5 is lifted up again to adjust the straight state of the packaging bag. After the adjustment is completed , the clamping robot arm 5 stops moving and fixes the packaging bag. The rear strapping component 3 and the roller device 4 work to glue and strap the packaging bag. After strapping is completed, the clamping device 2 moves upward again to cancel the clamping of the paper cup. At the same time, the clamping robot arm 5 can release the fixation of the packaging bag. The conveyor belt 1 continues to move and continues to transport the paper cups with the strapped packaging bag forward. When it contacts the support frame 6 during transportation, the support frame 6 will block the upper part of the paper cup, and the lower part of the paper cup continues to move forward, thereby pushing the paper cup down, so that the paper cup can fall smoothly into the placed collection frame.

[0033] In the above, the gripping robot 5 is a robot that can grip objects, and is composed of a robot arm, a fixture, and a control system; its principle is mainly based on air pressure, hydraulic pressure, electromagnetic principles, etc.

[0034] A fixture is a tool used by a robotic arm to clamp an object. Its design needs to be based on factors such as the geometry, mass, and material of the clamped object. In actual applications, precise positioning can be achieved through programming, and the clamping force of the fixture can also be adjusted as needed to ensure accurate clamping and operation of materials of different shapes and materials.

[0035] Further, in order to achieve the purpose of clamping the paper cup by the clamping device 2, refer to Figure 2The clamping device 2 includes two support columns 21, a spur gear 23 and a sliding rack 22. The inner cavities of the two support columns 21 are slidably connected to a sliding plate 27. The left and right parts of the upper ends of the sliding plate 27 are fixedly connected to an electric telescopic cylinder 26. The left and right parts of the lower ends of the sliding plate 27 are fixedly connected to a sliding rack 25. The two spur gears 23 are respectively rotatably connected to the middle parts of the inner cavities of the two support columns 21. The two sliding racks 22 are respectively slidably connected to the middle parts of the ends of the two support columns 21 that are away from each other. The ends of the two sliding racks 22 that are close to each other are fixedly connected to an arc plate 24.

[0036] The two spur gears 23 are respectively engaged with the sliding rack 1 22 and the sliding rack 2 25 on the same side.

[0037] In the above, the electric telescopic cylinder 26 is turned on to extend and retract, and the electric telescopic cylinder 26 drives the sliding plate 27 to slide in the inner cavity of the support column 21. When the sliding plate 27 slides downward, it will drive the sliding rack 25 to slide downward together. When the sliding rack 25 slides downward, it drives the spur gear 23 to rotate through the relationship of meshing with the spur gear 23. When the spur gear 23 rotates, it transmits power to the sliding rack 22 through the relationship of meshing with the sliding rack 22, driving the sliding rack 22 to move toward a part close to each other, driving the connected arc plate 24 to move together, and then clamping the paper cup, making the rear part more stable when bundling the packaging bag.

[0038] Further, in order to achieve the purpose of bundling the packaging bags by the clamping device 2 and the roller device 4, refer to Figure 3 、 Figure 4 and Figure 5 The strapping assembly 3 includes a stepping motor 31 and a strapping mechanism 32. The stepping motor 31 is fixedly connected to the rear side of the middle portion of the upper end of the sliding plate 27, and the strapping mechanism 32 is fixedly connected to the rear side of the middle portion of the lower end of the sliding plate 27.

[0039] The tying mechanism 32 includes a housing 321, which is fixedly connected to the rear middle portion of the lower end of the sliding plate 27. The front and rear middle portions of the bottom wall of the housing 321 are rotatably connected to winding shafts 323, and the two winding shafts 323 are commonly wound around the tying patch 322.

[0040] The winding shaft 323 at the front is fixedly connected to the output end of the stepping motor 31;

[0041] The roller device 4 includes a support block 41, which is fixedly connected to the right part of the sliding plate 27. The middle part of the upper end of the support block 41 is fixedly connected to the electric telescopic cylinder 2 42, and the output end of the electric telescopic cylinder 2 42 is fixedly connected to the connecting frame 43. The left part of the connecting frame 43 is rotatably connected to two rollers 44.

[0042] In the above, when the curved plate 24 clamps the paper cup, the stepper motor 31 is started to rotate. When the stepper motor 31 rotates, the winding shaft 323 connected to it is driven to rotate through the coupling. When the winding shaft 323 at the front rotates, the binding sticker 322 is wrapped around itself, and the binding sticker 322 slides out of the winding shaft 323 at the rear, and then slides on the outer surface of the shell 321, and then enters the winding shaft 323 at the front from the entrance. The outer surface of the binding sticker 322 is adhered with an adhesive sheet. When the binding sticker 322 moves to the raised position of the shell 321, the adhesive sheet It will automatically detach from the outer surface of the strapping sticker 322. When the adhesive sheet is about to be detached, the stepping motor 31 stops rotating, so that the adhesive sheet is in a state of being almost detached. Then the electric telescopic cylinder 42 is controlled to be extended and retracted, so that the electric telescopic cylinder 42 drives the connecting frame 43 to move toward a part close to the shell 321. When the connecting frame 43 moves, it drives the roller 44 to move together, so that the roller 44 adheres the adhesive sheet to the packaging bag, thereby completing the strapping of the packaging bag. Then the electric telescopic cylinder 42 retracts to its original position, and the sliding plate 27 rises to its original position to strap the next packaging bag.

[0043] In the above description, the clamping robot arm 5 clamps the packaging table in an upright position below the front portion of the housing 321 so that the adhesive sheet on the binding sticker 322 can be attached to the packaging table.

[0044] In the above, the connection between the winding shaft 323 at the rear and the bottom wall of the shell 321 is coated with friction paint, so that when the stepper motor 31 does not drive the winding shaft 323 at the front to rotate, the winding shaft 323 at the rear will not rotate due to inertia, so that the binding patch 322 can be tightened on the shell 321.

[0045] It should be noted that the specific installation methods, circuit connection methods and control methods of the clamping robot arm 5, electric telescopic cylinder 1 26, stepper motor 31 and electric telescopic cylinder 2 42 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
