Description

Technical Field

[0001] This utility model relates to a reciprocating feeding mechanism for a cup stacking machine. Background Technology

[0002] In the current packaging machinery design process, different styles of packaging containers, such as cups and bowls, require material preparation, crushing, and hot-melt molding before being discharged. The finished packaging containers are generally individual containers with their openings facing upwards. To meet subsequent production needs, these individual packaging containers need to be stacked to save space and facilitate subsequent discharge. To improve stacking efficiency, the packaging containers can be initially arranged into an array. A row of suction cups in the same array is used to pick up the packaging containers and place them into a cup receiving container. This process is repeated to achieve large-scale simultaneous stacking. However, large-scale stacking also has drawbacks. To send the stacked packaging containers to the next process, they need to be ejected one by one before the cup receiving container can be freed up for the next round of stacking, which affects production efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a reciprocating feeding mechanism for a stacking cup machine. By setting two sets of conveying components, when one set of cup receivers stacks packaging containers from the cup feeder, the other set of cup receivers pushes the containers out from the top cup feeder. After production is completed, the two sets of cup receivers replace each other from the top and bottom ends respectively, realizing continuous cyclic production and improving production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A reciprocating feeding mechanism for a stacking cup machine includes a frame, a cup feeder, a conveying assembly, and a cup top feeder. The cup feeder and cup top feeder are respectively disposed at the front and rear ends of the frame. The conveying assembly includes a cup receiver, a lifting component, and a lateral movement component. The cup receiver is disposed on the lifting component and driven to move vertically. The lifting component is disposed on the lateral movement component and driven to move laterally between the cup feeder and the cup top feeder. The lateral movement component is disposed on the frame. The conveying assembly includes two sets, which are respectively disposed at the left and right ends of the frame. The two sets of conveying assemblies are interchangeable between the cup feeder and the cup top feeder.

[0006] The lifting component includes a lifting seat, an upper clamping plate, a lower clamping plate, a lifting rod, and a lifting motor. The upper and lower clamping plates are movably connected to the transverse moving component, and the lifting rod is rotatably connected between the upper and lower clamping plates. The lifting rod has an external thread, and the lifting seat has a threaded hole that mates with the external thread. The cup receiver is mounted on the lifting seat, and the lifting motor is mounted on the lower clamping plate. The output end of the lifting motor is connected to the lifting rod and drives the lifting rod to rotate.

[0007] The transverse component includes an upper slide block, an upper slide rail, a lower slide block, a lower slide rail, a front wheel, a rear wheel, a belt, and a drive motor. The upper slide block is mounted on the upper clamping plate and cooperates with the upper slide rail on the frame. The lower slide block is mounted on the lower clamping plate and cooperates with the lower slide rail on the frame. The front wheel and the rear wheel are rotatably connected to the front and rear ends of the frame, respectively, and are connected by a belt. The lower clamping plate is connected to the belt. The drive motor is mounted on the frame, and its output end is connected to the rear wheel and drives the rear wheel to rotate.

[0008] The reciprocating feeding mechanism of the stacking cup machine with this structure receives packaging containers stacked from top to bottom at the cup feeder. After stacking, the cup receiver needs to be moved to the top cup device to push out the stacked packaging containers and send them to the next process. In order to achieve a system where one set of cup receivers receives the stacks and another set of cup receivers pushes out the containers, and then the positions are exchanged after completion, so as to minimize production downtime and improve production efficiency, two sets of conveying components are set up to achieve mutual replacement production. One set of conveying components gradually lowers its position during the process of receiving packaging containers, while the other set of conveying components gradually rises during the process of pushing out packaging containers. This achieves the vertical misalignment of the cup receivers from the horizontal level. Then, through the horizontal moving components, they move and stagger relative to each other, and finally enter their respective workstations, reducing the downtime between them.

[0009] To ensure smooth operation of the cup receiver during lifting, an upper clamping plate and a lower clamping plate are installed. The upper and lower ends of the cup receiver are fixed to the upper and lower slide rails via upper and lower sliding seats. The cup receiver is then mounted on a lifting seat between the upper and lower clamping plates. To allow the lifting seat to move up and down, threaded holes are provided on it. These threaded holes are fitted onto the external threads of the lifting rod between the upper and lower clamping plates. As a result, the lifting rod can convert its rotational motion into linear motion during rotation, driving the cup receiver to move up and down under the drive of the lifting motor.

[0010] To achieve smooth lateral displacement, the upper and lower slide rails are first installed so that the upper and lower slide blocks can move laterally along the direction of the upper and lower slide rails. The cooperation between the slide rails and the slide blocks can also bear sufficient weight, so that the cup receiver can run smoothly in the lateral movement. In order to drive the movement of the cup receiver, the front and rear rotating wheels are set on the frame and driven by belt transmission. The drive motor drives the rear rotating wheel, so that the lower clamping plate on the belt is pushed laterally and moves horizontally.

[0011] Furthermore, the opening of the upper slide is downward, and the opening of the lower slide is upward, with the upper slide and the lower slide corresponding vertically.

[0012] Compared with the prior art, the advantages of this utility model are as follows: by setting up two sets of conveying components to achieve production through mutual substitution, the cup receiving device of one set of conveying components gradually descends its position as the lifting seat receives the packaging container, while the cup receiving device of the other set of conveying components gradually rises as the lifting seat ejects the packaging container, so that the upper and lower positions of the cup receiving devices are staggered in the horizontal plane, ensuring that they do not interfere with each other during the horizontal movement. Then, through the horizontal moving components of each other, they move and stagger relative to each other, and finally enter their respective workstations, reducing the downtime between each other and improving production efficiency.

[0029] Description of the working principle of this utility model:

[0030] The reciprocating feeding mechanism of the stacking cup machine using this structure has a cylindrical cup receiver 31. The diameter of the upper opening is larger than that of the lower opening. This is to allow packaging containers to enter from top to bottom, but restricts their passage from below, preventing them from falling and facilitating transfer. This structure is a commonly used existing technology, so it will not be described in detail. The cup receiver 31 is located at the cup feeder 2 and receives packaging containers stacked from top to bottom. After stacking, the cup receiver 31 needs to be moved to the top cup feeder 4 to push out the stacked packaging containers and send them to the next process. In order to achieve a set of... The cup receiver 31 receives the stacked cups, and a set of cup receivers 31 ejects the material. After completion, they exchange positions to minimize production downtime and improve production efficiency. Therefore, two sets of conveyor components 3 are set up to achieve mutual replacement production. One set of conveyor components 3 gradually lowers its position during the process of receiving the packaging container, while the other set of conveyor components 3 gradually rises during the process of ejecting the packaging container. This achieves the vertical misalignment of the cup receivers 31 from the horizontal level. Then, they are moved and staggered relative to each other by the lateral moving components 33, and finally enter their respective workstations to reduce each other's downtime.

[0031] To ensure smooth operation of the cup receiver 31 during lifting, an upper clamping plate 322 and a lower clamping plate 323 are provided. The upper and lower ends of the cup receiver 31 are connected to the upper slide rail 332 and the lower slide rail 334 via the upper slide block 331 and the lower slide block 333 to fix their positions. The cup receiver 31 is set on the lifting seat 321 between the upper clamping plate 322 and the lower clamping plate 323. To enable the lifting seat 321 to move up and down, a threaded hole 3211 is provided on the lifting seat 321. The threaded hole 3211 is connected to the external thread 3241 of the lifting rod 324 between the upper clamping plate 322 and the lower clamping plate 323. Therefore, during the rotation of the lifting rod 324, the rotational motion can be converted into linear motion, which drives the cup receiver 31 to move up and down under the drive of the lifting motor 325.

[0032] To achieve smooth lateral displacement, the upper slide rail 332 and the lower slide rail 334 are first set up so that the upper and lower slide blocks can move laterally along the direction laid by the upper slide rail 332 and the lower slide rail 334. The cooperation between the slide rail and the slide block can also bear enough weight so that the cup receiver 31 can run smoothly in the lateral movement. In order to drive the movement of the cup receiver 31, the front rotating wheel 335 and the rear rotating wheel 336 are set on the frame 1 and driven by the belt 337. The drive motor 338 drives the rear rotating wheel 336 so that the lower clamping plate 323 on the belt 337 is pushed laterally and moves horizontally.

[0033] With the opening of the upper slide 331 facing downwards and the opening of the lower slide 333 facing upwards, the upper slide 331 and the lower slide 333 correspond vertically. Therefore, the upper clamping plate 322 and the lower clamping plate 323 can clamp the frame 1 vertically, preventing it from coming off from above or below and improving the operational stability of the equipment.

[0034] The beneficial effects of this utility model are as follows: by setting up two sets of conveying components 3 to achieve production through mutual substitution, the cup receiving device 31 of one set of conveying components 3 gradually descends its position as the lifting seat 321 receives the packaging container, while the cup receiving device 31 of the other set of conveying components 3 gradually rises as the lifting seat 321 ejects the packaging container, so that the upper and lower positions of the cup receiving devices 31 are staggered in the horizontal plane, ensuring that they do not interfere with each other during the horizontal movement. Then, they are moved and staggered relative to each other by the horizontal moving components 33, and finally enter their respective workstations, reducing the downtime between them and improving production efficiency.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
