Description

Technical Field

[0001] This utility model relates to the field of plastic cap production technology, specifically to a plastic cap collection device. Background Technology

[0002] The freshly made beverage industry, including milk tea, is developing rapidly, leading to a surge in demand for plastic lids for milk tea paper cups. The level of automation in the production and packaging processes directly affects the company's production capacity. In the post-processing stage of plastic lids, the molded plastic lids need to be collected and stacked in an orderly manner for subsequent packing and transportation.

[0003] Existing collection methods are mainly divided into two categories: manual collection and mechanical collection. Manual collection relies on workers to manually pick up plastic caps and stack them neatly. This is not only labor-intensive and costly, but also prone to causing the plastic caps to be stacked crookedly or damaged due to operational errors. Moreover, the collection efficiency is far from matching the high-speed output requirements of automated production lines. Mechanical collection mostly uses a structure of conveyor belts combined with fixed stacking racks. When a single stacking rack is full, the machine needs to be stopped to replace the empty stacking rack. This process interrupts the entire collection process, causing the production line to stop and wait, which seriously affects continuous production efficiency. Especially during peak production periods, the capacity loss caused by stopping to replace racks is even more significant. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plastic cap collection device, comprising a main frame, on which a drive rotating table is mounted, and a feeding assembly is mounted above the drive rotating table. The drive rotating table has multiple C-shaped openings, and a stacking rack is installed at each of the C-shaped openings. The stacking rack includes a large C-shaped plate fastened to the drive rotating table at the C-shaped opening by screws. Multiple columns are fixed to the bottom of the large C-shaped plate, and small C-shaped plates are fixed between the bottoms of the columns. The feeding assembly includes an upper frame, on which a rotary motor is mounted. A rotating plate is fixed to the shaft end of the rotary motor. An annular cylinder is fixed to the bottom of the rotating plate, and a base plate is fixed to the bottom of the annular cylinder. Two sets of lifting parts are mounted on the top of the base plate. A top feeding plate is fixed to the lifting end of each lifting part, and an adsorption device is installed at the bottom of the top feeding plate.

[0005] Furthermore, a connecting plate is fastened between the bottoms of adjacent small C-shaped plates by screws.

[0006] Furthermore, the drive box of the drive turntable has a vertical rod that passes through the turntable, and a top block is fixed to the top of the vertical rod. Multiple fan-shaped stop bars are threaded to the outside of the top block, and one end of the stop bars extends to the top of the stacking rack.

[0007] Furthermore, a lifting assembly is fixed inside the main frame. The lifting assembly includes a vertical plate and a belt drive device. A screw device that is connected to the belt drive device is vertically installed on the vertical plate. A lifting plate that slides with the vertical plate is fixed at the nut end of the screw device. A top cylinder that is located below the stacking rack and can be extended to is fixed on the lifting plate.

[0008] Furthermore, the lifting unit includes a mounting base fixed to the bottom of the rotating plate, a top-feeding cylinder is fixed inside the mounting base, the piston rod of the top-feeding cylinder passes through the bottom plate and is fixed to the top-feeding plate, and multiple guide rods are fixed to the top of the top-feeding plate, the guide rods can pass through the mounting base and the rotating plate.

[0009] Furthermore, a spring is sleeved on the outer side of the guide rod between the mounting base and the base plate.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] The plastic cap collection device uses a rotating platform with multiple C-shaped openings equipped with stacking racks. When a full stacking rack rotates to the pick-up / placement station, an empty stacking rack simultaneously switches to the stacking station. The feeding component does not need to stop and wait, significantly improving collection efficiency, reducing production capacity loss, and enabling continuous collection. The lifting component drives a lead screw device via a belt drive to achieve precise downward movement of the top cylinder. Combined with the limiting effect of the column and the C-shaped structure of the stacking rack, it can support the plastic caps to move downward and complete the stacking, preventing tilting.

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] Please see Figure 1-4 This embodiment of a plastic cap collection device includes a main frame 1, on which a drive rotary table 2 and a feeding assembly 5 are mounted. The drive rotary table 2 has multiple outward-facing C-shaped openings, and stacking racks 3 are screwed into these C-shaped openings. Empty stacking racks are first locked one by one into the C-shaped openings on the drive rotary table. The feeding assembly then transfers the plastic caps one by one into the stacking racks for stacking and collection until the table is full. Then, by rotating the drive rotary table, the full stacking racks and empty stacking racks are swapped, with the empty racks positioned in the collection position. When the full stacking racks move to the unloading position, the empty racks can then remove the full stacking racks and install the stacking racks with holes. Therefore, continuous stacking and collection can be achieved without stopping the machine.

[0019] like Figure 2 The stacking rack 3 includes a large C-shaped plate 33 that is fixed to the C-shaped opening of the drive rotating table 2 by screws. At least seven uprights 32 are fixed to the bottom of the large C-shaped plate 33. The uprights 32 pass through the large C-shaped plate 33. Small C-shaped plates 31 for plastic covers are fixed between the bottoms of the uprights 32. The small C-shaped plates 31 cooperate with the uprights to support and limit the plastic covers, preventing them from shifting. The bottoms of adjacent small C-shaped plates 31 are fixed to connecting plates 34 by screws, which enhances the overall structural rigidity of the stacking rack and prevents the rack from deforming or shifting during stacking. When it is necessary to remove the corresponding stacking rack, when the full stacking rack is moved to the unloading position, the screws on the corresponding large C-shaped plate and the screws on the corresponding connecting plate of the small C-shaped plate 31 are removed, and the corresponding stacking rack can be removed. The above operation is repeated to fix the empty stacking rack to the corresponding position.

[0020] The drive box of the drive turntable 2 has a fixed upright rod 6 inside. The upright rod 6 passes through the drive box and the turntable of the drive turntable 2. The top of the upright rod 6 is fixed with a top block 7. The top block 7 is threaded with seven fan-shaped stop bars 8. The seven stop bars 8 are located above the corresponding stacking rack 3 and are used to limit the stacking rack and the plastic cover in the stacking rack. When the stacking rack needs to be removed, the stop bars must be unscrewed first.

[0021] like Figure 4The feeding assembly 5 is used to grab plastic caps and transfer them to the stacking rack. It includes an upper frame 51 fixed on the main frame 1. A rotary motor 52 is installed on the top of the upper frame 51, and a rotating plate 53 is fixed to the output shaft end of the upper frame 51. The rotating plate 53 is rectangular and has rectangular holes at both ends. The rotary motor can drive the rotating plate 53 to rotate, realizing the transfer of plastic caps from the feeding station to the stacking station. An annular cylinder 54 is fixed to the bottom of the rotating plate 53, and a base plate 55 is fixed to the bottom of the annular cylinder 54. Two sets of mounting seats 56 are installed at the bottom of the rotating plate 53. A top-feeding cylinder 57 is installed in the middle of the inner side of the mounting base 56. Its piston rod passes through the base plate 55 and is fixed to the top-feeding plate 510. The top-feeding cylinder can drive the top-feeding plate to move up and down. An adsorption device 511 is installed at the bottom of the top-feeding plate 510. The adsorption device 511 is preferably a vacuum suction cup to achieve flexible gripping and avoid damage to the plastic cover. A pair of guide rods 58 are fixed at the top of the top-feeding plate 510, passing through the base plate 55, the mounting base 56 and the rotating plate 53. The guide rods improve the stability of the top-feeding plate's lifting and lowering.

[0022] Among them, a spring 59 is sleeved on the outer side of the guide rod 58, and the spring 59 is located between the mounting base 56 and the base plate 55, which plays a buffering role and prevents the excessive driving force of the top delivery cylinder from damaging the plastic cover.

[0023] The main frame 1 is also equipped with a lifting assembly 4 located below the drive turntable 2, which is used to drive the plastic covers to move down gradually to achieve multi-layer stacking. The lifting assembly 4 includes a vertical plate 41 fixed on the main frame 1 and a belt drive device 43. A lead screw device 42 is installed on the side of the vertical plate 41 facing the drive turntable 2. The lead screw device 42 is connected to the belt drive device 43. The belt drive device includes a servo motor, a drive wheel, a driven wheel and a transmission belt. The driven wheel is fixed to the lead screw and can drive the lead screw to rotate. A lifting plate 44 is fixed to the nut end of the lead screw device 42. The lifting plate 44 is slidably connected to the vertical plate 41. The rotation of the lead screw can drive the lifting plate 44 to move up and down. A top cylinder 45 is fixed on the side of the lifting plate 44 facing the drive turntable 2. The top cylinder 45 can extend to the inside of the small C-shaped plate 31 of the stacking rack 3 to support the stacked plastic covers. As the lifting plate 44 moves down, it reserves space for the next layer of plastic covers.

[0024] The working principle of the above embodiments is as follows:

[0025] Multiple empty stacking racks are fixed to the C-shaped opening of the drive rotary table with screws, ensuring a tight fit between the large C-shaped plate and the rotary table. The position of the stop bar is adjusted so that it is at the upper limit of the stacking rack. The belt drive device is started, and the drive screw device moves the lifting plate and top cylinder to the inner top of one of the stacking racks to the initial position. The rotary motor starts, and the drive plate moves the suction device to the feeding station. The piston rod of the top conveying cylinder extends, moving the top conveying plate and suction device downward until the suction cup contacts the plastic cover. The suction device draws a vacuum, firmly adhering to the plastic cover. The piston rod of the top conveying cylinder retracts, moving the plastic cover upward. The guide rod ensures the straightness of the upward trajectory, and the spring buffers the impact. The rotary motor drives the turntable to rotate the adsorbed plastic cover to the stacking station, which is located above one set of stacking racks. Directly above the top cylinder, the top-feeding cylinder extends, sending the plastic cover to the top of the top cylinder. The adsorption device is then closed, and the plastic cover falls smoothly onto the top cylinder. The belt drive device starts, driving the screw device to lower the lifting plate by the height of one plastic cover, reserving space for the next layer of stacking. The grabbing and stacking steps are repeated until the current stacking rack is full. Once the current stacking rack is full, the drive turntable rotates, moving the full stacking rack to the pick-up and drop-off station, where workers can disassemble and replace it. At the same time, the empty stacking rack is moved to the stacking station. During the rack replacement process, the feeding component can continue to grab plastic covers. Once the empty rack is in place, it can be stacked directly without stopping the machine. Workers can remove the rack by first unscrewing the corresponding stop bar and the screws on the large C-shaped plate on the full stacking rack, as well as the connecting plate screws that fasten the small C-shaped plate with screws. After replacing the empty rack, it can be re-fixed. The operation is convenient.
