Description

Technical Field

[0001] This utility model relates to the field of plastic cup production technology, and more specifically to a fully automatic cup stacking device for plastic cup production. Background Technology

[0002] The production process of plastic cups involves molding, cleaning, testing, stacking, and packaging. Stacking refers to the process of stacking the molded plastic cups to facilitate subsequent operations.

[0003] In the field of plastic cup stacking production, fully automatic cup stacking devices are the core equipment for achieving efficient stacking and collection. Traditional cup stacking equipment adopts a fixed guiding structure and can only handle plastic cups of a single specification. With the diversification of market demand for plastic cups, traditional equipment cannot meet the production needs of multiple varieties and small batches, nor can it meet the current market demand for diversified and efficient production. Even if some equipment has built-in adjustment functions, it is still necessary to stop the machine to change the mold or manually and cumbersomely adjust the mechanical parts when producing cups of different radii, which is difficult to operate and time-consuming. Utility Model Content

[0004] This utility model provides a fully automatic cup stacking device for plastic cup production. Its advantage is that it can stack plastic cups of different radii through simple adjustment and operation, which brings convenience to the processing.

[0005] A fully automatic cup stacking device for plastic cup production includes a vertical rod and a lifting structure. A connecting plate is fixedly connected to the vertical rod, and a slider is slidably connected to the vertical rod. Multiple slide rails are fixedly connected to the connecting plate, and a guide rod is slidably connected to each slide rail. One end of multiple hinge rods is hinged to the slider, and the other end of the multiple hinge rods is respectively hinged to the multiple guide rods. A blocking structure is connected to the vertical rod, which can block plastic cups from entering between the multiple guide rods. The lifting structure can move up and down in the vertical direction.

[0006] The blocking structure includes a fixed block connected to a vertical rod, a T-shaped rod slidably connected to the fixed block, a wedge-shaped block slidably connected to the T-shaped rod, a mating plate fixedly connected to the wedge-shaped block, and a compression spring B fixedly connected between the mating plate and the T-shaped rod.

[0007] The spring force that compression spring A can provide is greater than the spring force that compression spring B can provide.

[0008] It also includes an L-shaped rod that is fixed between the fixed block and the vertical rod.

[0009] A first electric push rod is fixedly connected to the L-shaped rod, and the telescopic rod of the first electric push rod is fixedly connected to the connecting piece.

[0010] Two of the guide rods have extension rods fixed to them. Attached Figure Description

[0017] Figure 7 This is a schematic diagram of the second electric actuator. Detailed Implementation

[0018] A fully automatic cup stacking device for plastic cup production includes a vertical rod 102, a connecting piece 201 integrally formed on the vertical rod 102, a slider 401 slidably connected to the vertical rod 102, and multiple slide rails 202 welded and fixed to the connecting piece 201. Each slide rail 202 is slidably connected to a guide rod 403 through a groove. The upper ends of multiple hinge rods 402 are rotatably connected to the slider 401 through multiple shafts. The lower ends of the multiple hinge rods 402 are rotatably connected to the multiple guide rods 403 through shafts. A blocking structure and a lifting structure are connected to the vertical rod 102. The blocking structure can block plastic cups from entering between the multiple guide rods 403, and the lifting structure can move up and down in the vertical direction. The multiple hinge rods 402 and multiple guide rods 403 are evenly distributed along a circumferential trajectory.

[0019] This equipment is installed at one end of a conveyor belt that can automatically and continuously transport frustum-shaped plastic cups that are narrower at the top and wider at the bottom. During the transportation process, the frustum-shaped plastic cups are placed upside down on the conveyor belt, and after being upside down, they form a frustum shape that is narrower at the top and wider at the bottom.

[0020] As the conveyor belt transports the cups, once a plastic cup moves to a position where it can be lifted by the lifting structure, the lifting structure moves upward, lifting the inverted plastic cup between multiple guide rods 403 until the plastic cup moves to the top of the blocking structure. During this process, the multiple guide rods 403 guide the plastic cup, allowing it to be lifted upward in a neat and stable manner. Then, the second electric push rod 501 slides down to reset, at which point the blocking structure blocks the plastic cup that was just lifted, storing it on the top of the blocking structure. Then, the conveyor belt is restarted to move the next plastic cup to a position where it can be lifted by the lifting structure, and the above operation is repeated to complete the fully automatic stacking of the plastic cups. The multiple guide rods 403 ensure that the multiple plastic cups can be neatly inserted and cooperated with each other during the stacking process, guaranteeing the smooth operation of the fully automatic stacking.

[0021] In practical use, the slider 401 can be operated to slide on the vertical rod 102 according to the actual radius of the plastic cups to be stacked. This causes the upper ends of multiple hinge rods 402 to move synchronously with the slider 401. During this process, the other ends of the multiple hinge rods 402 will pull multiple guide rods 403 to slide on multiple slide rails 202, thereby changing the circumference of the circular trajectory formed by the lines connecting the multiple guide rods 403. This allows the multiple guide rods 403 to guide plastic cups of different radii. In other words, the stacking effect of plastic cups of different radii can be achieved by operating a single sliding slider 401. This enables the equipment to perform stacking operations on plastic cups of different radii, expanding the applicability of the equipment. Furthermore, by simple adjustment, the stacking effect of plastic cups of different radii can be achieved, bringing convenience to the processing.

[0022] After the cups are stacked, a robotic arm with clamps is used to grip the stacked plastic cups. Then, the slider 401 is slid upwards, causing the multiple guide rods 403 to move away from each other, so that the stacked plastic cups can be easily removed, completing the collection operation.

[0023] The robotic arm with grippers is a common technique in the prior art and is not within the scope of protection of this application, so it will not be described in detail here.

[0024] The blocking structure includes a fixing block 103 connected to the vertical rod 102, a T-shaped rod 301 slidably connected to the fixing block 103, a wedge block 303 slidably connected to the T-shaped rod 301, a mating plate 304 fixedly connected to the wedge block 303, a compression spring B305 fixedly connected between the mating plate 304 and the T-shaped rod 301, and an inclined surface on the wedge block 303 facing downward.

[0025] As the plastic cup is lifted upwards and passes the wedge block 303, the plastic cup slides against the inclined plane, causing the compression spring B305 to compress. That is, the wedge block 303 slides on the T-shaped rod 301 against the elastic force of the compression spring B305. After the plastic cup has completely passed the inclined plane, the wedge block 303 will automatically reset under the elastic force of the compression spring B305, thus blocking the plastic cup. At this time, the wedge block 303 can block the plastic cup. Then, the lifting operation of the plastic cup is repeated to complete the stacking effect of the plastic cups and realize the fully automatic stacking operation.

[0026] The T-shaped rod 301 is slidably connected to the fixed block 103 through a slot. A rectangular plate is integrally formed on the T-shaped rod 301, and a compression spring A302 is welded and fixed between the rectangular plate and the fixed block 103.

[0027] During the sliding process of the sliding slider 401, which causes multiple guide rods 403 to slide under the action of multiple hinge rods 402, the rectangular plate is always subjected to the elastic force of the compression spring A302, which in turn causes the T-shaped rod 301 to slide adaptively on the fixed block 103. This ensures that the wedge block 303 always abuts against the two guide rods 403 closest to the conveyor belt. When the space between the multiple guide rods 403 is adjusted, the positions of the T-shaped rod 301 and the wedge block 303 will also be adjusted adaptively, so that the wedge block 303 can block plastic cups of different radii, further improving the effect of this equipment in stacking plastic cups of different radii.

[0028] The spring force provided by spring A302 is greater than that provided by spring B305.

[0029] This setting ensures that during the upward lifting of the plastic cup, only the wedge block 303 will slide on the T-shaped rod 301, and the T-shaped rod 301 will not slide on the L-shaped rod 101. This ensures that the T-shaped rod 301 will only be pushed by the two guide rods 403 on the side closest to the conveyor belt, thus ensuring a stable subsequent blocking effect.

[0030] The sliding design of the wedge block 303 and the T-shaped rod 301 allows the T-shaped rod 301 or the wedge block 303 to be replaced individually by cutting the compression spring B305 or the compression spring A302 after a component is deformed due to frequent use. This reduces the subsequent economic operating cost of the equipment. At the same time, compared with the integrated design of the wedge block 303 and the T-shaped rod 301, the above sliding setting can significantly reduce the number of compressions of the compression spring A302, ensuring that the T-shaped rod 301 can abut against the two guide rods 403 near the conveyor belt for a long time.

[0031] It also includes an L-shaped rod 101 that is welded and fixed between the fixed block 103 and the vertical rod 102.

[0032] The L-shaped rod 101 can connect the fixing block 103 and the vertical rod 102. Subsequently, the fixing block 103 and the vertical rod 102 can be fixed by screwing bolts into the L-shaped rod 101.

[0033] The L-shaped rod 101 is fixedly connected to the first electric push rod 406 by bolts. A circular piece is integrally formed on the connecting piece 201. The telescopic rod of the first electric push rod 406 is fixedly connected to the circular piece on the connecting piece 201 by bolts.

[0034] When the slider 401 needs to slide up and down, the telescopic rod of the first electric push rod 406 is moved, thereby causing the slider 401 to slide on the vertical rod 102, which in turn drives multiple hinge rods 402 and multiple guide rods 403 to slide, thus achieving the spatial effect of adjusting the multiple guide rods 403 according to production needs.

[0035] Extension rods 404 are welded and fixed to two of the guide rods 403 that are far from the conveyor belt.

[0036] Before lifting the plastic cups, the plastic cups detached from the conveyor belt are placed against the two extension rods 404, and then the upward lifting operation is performed to ensure that subsequent plastic cups can smoothly enter the space between the multiple guide rods 403, further facilitating the smooth operation of the fully automatic cup stacking.

[0037] Each extension rod 404 has a transverse rod 405 integrally formed on it.

[0038] After the plastic cups detach from the conveyor belt, they enter the area where the horizontal bars 405 are located and are placed on the upper side of the two horizontal bars 405. Subsequently, due to the continuous operation of the conveyor belt, the plastic cups will be squeezed against each other until the plastic cups are pressed against the two extension bars 404. Then the conveyor belt can be stopped and the lifting structure can be used to move and complete the subsequent stacking effect.

[0039] The lifting structure includes a lower plate 503, on which a second electric push rod 501 is fixed by bolts.

[0040] The lower plate 503 is fixed by screwing bolts into it. The second electric push rod 501 is then activated, causing its telescopic rod to push the plastic cup upwards, thus completing the subsequent cup stacking operation.

[0041] A lifting plate 502 is bolted to the telescopic rod of the second electric push rod 501.

[0042] In practical use, if the surface of the plastic cup is too smooth, a simple upward lifting operation is not enough to achieve a stable lifting effect. If a more stable lifting effect is required, a circular plate with the same narrowest radius as the inverted plastic cup can be connected to the lifting plate 502 by tightening bolts according to the actual size of the cups to be stacked. This allows the circular plate to contact the top of the inverted plastic cup when the telescopic rod extends, thus enabling the circular plate to lift the plastic cup upward in a more stable and orderly manner, further ensuring the smooth progress of subsequent cup stacking operations.
