Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment. More specifically, this utility model relates to a plastic packaging lid stacking device. Background Technology

[0002] The disposable plastic lids used for boxed ice cream are typically first compression molded, and then graphics and text are printed on the top of the molded lid. To ensure a stable connection between the ice cream box and the plastic lid, the plastic lids used for boxed ice cream have a downward-curving center and outward-flaring edges. The compression-molded lids are individually fed into the printing equipment with their front faces up. After printing, they leave the printing equipment one by one and are then collected and packaged. Packaging requires stacking many plastic lids together. Currently, this is mainly done manually, but the collection speed is too slow and inefficient, affecting the packaging process. Utility Model Content

[0034] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0035] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0036] Figures 1-2 A plastic packaging cap stacking device provided for an embodiment of the present invention includes:

[0037] The vertical plate 1 has two vertically arranged guide plates 2 spaced apart on one side, forming a material guiding channel between the two guide plates 2;

[0038] Two vertically arranged rotating cylinders 3 are respectively positioned below the two guide plates 2. Threaded blades 4 are coaxially sleeved on the rotating cylinders 3, and the spiral directions of the two threaded blades 4 are opposite. A feeding position communicating with the material guide channel is formed between the two rotating cylinders 3. The guide plates 2 extend downwards, and their lower ends are provided with notches corresponding to the rotating cylinders 3. The upper ends of the rotating cylinders 3 are located within the notches, and the threaded blades 4 are located below the guide plates 2.

[0039] A drive mechanism is mounted on the vertical plate 1 and is connected to the two rotating drums 3 in a transmission manner. The drive mechanism drives the two rotating drums 3 to rotate synchronously in opposite directions.

[0040] In this embodiment, two rotating cylinders 3 are spaced apart to the left and right, and the two rotating cylinders 3 and the vertical plate 1 together form a cavity that matches the plastic packaging cap 16. The front end of the cavity is open. Figure 1 The area between the dashed lines L1 and L2 serves as the inlet of the cavity. This inlet can be connected to a horizontal conveyor, allowing plastic packaging caps 16 to be conveyed horizontally to the inlet sequentially. The plastic packaging caps 16 enter the cavity horizontally through the inlet and rest on two threaded blades 4. The edges of the plastic packaging caps 16 slide against the two cylinders and the vertical plate 1, ensuring they can only move vertically within the cavity. The threaded blades 4 have opposite helical directions, and the drive mechanism drives the two rotating cylinders 3 to rotate synchronously in opposite directions. During the rotation of the two threaded blades 4, a force is applied to the plastic packaging caps 16 between them. Combined with the cavity's limitation on the movement trajectory of the plastic packaging caps 16, the two threaded blades 4 drive the plastic packaging caps 16 between them to move upwards. Figure 1 As shown, the spiral blade rotates more than once. At this time, there are multiple plastic packaging covers 16 between the two rotating drums 3. When the plastic packaging cover 16 moves upward and separates from the spiral blade 4, it falls onto the plastic packaging cover 16 below it. The lower end of the upper plastic packaging cover 16 is embedded in the groove of the lower plastic packaging cover 16, completing the stacking. Then, it moves upward together with the lower plastic packaging cover 16 and enters the guide channel, as shown... Figure 2 As shown. Similarly, as plastic packaging covers 16 are continuously fed into the stacking device, multiple plastic packaging covers 16 are stacked and enter the guide channel. When the plastic packaging covers 16 accumulate to a certain extent in the guide channel, the workers can take out the stacked plastic packaging covers 16 for packaging.

[0041] Preferably, in another embodiment of the present invention, the driving mechanism includes:

[0042] A support frame 5 is connected to the vertical plate 1. A rotating shaft 6 is coaxially provided at the lower end of the rotating cylinder 3. The rotating shaft 6 is rotatably connected to the support frame 5 through a bearing seat.

[0043] The first gear 7 is coaxially mounted on each of the rotating shafts 6;

[0044] The drive motor 8 is fixed on the support frame 5, and its output shaft is vertically upward.

[0045] The second gear 9 is coaxially mounted on the output shaft of the drive motor 8, and is disposed between the two first gears 7 and meshes with them respectively.

[0046] In this embodiment, the drive motor 8 drives the second gear 9 to rotate. The second gear 9 is located between the two first gears 7, driving them to rotate synchronously. At this time, the two second gears 9 rotate in opposite directions, thereby enabling the rotating drum 3 to rotate synchronously in opposite directions.

[0047] Preferably, as another embodiment of this utility model, such as Figure 3-6 As shown, it also includes:

[0048] A separation mechanism is disposed at the opening above the feed channel; the separation mechanism includes two sets of separation units arranged at left and right intervals, each separation unit comprising:

[0049] The first mounting bracket 10 is disposed on the vertical plate 1;

[0050] The first telescopic bar 11 has its cylinder body fixed on the first mounting bracket 10, and its push rod is set in the left-right direction;

[0051] The separation plate 12 is horizontally arranged and connected to the push rod of the first telescopic bar 11. The two separation plates 12 are provided with a downwardly inclined section at one end that is close to each other.

[0052] A horizontal pushing mechanism is disposed above the separating mechanism, the horizontal pushing mechanism comprising:

[0053] The second mounting bracket 13 is disposed on the vertical plate 1;

[0054] The second telescopic bar 14 has its cylinder body fixed on the second mounting bracket 13, and its push rod is set in the left-right direction;

[0055] The push plate 15 is vertically arranged and connected to the push rod of the second telescopic bar 14.

[0056] In this embodiment, in order to automatically separate the stacked plastic packaging covers 16, a separation mechanism is provided to separate the multiple plastic packaging covers 16 on top and push them out horizontally by a horizontal pushing mechanism, so that workers can easily pick them up.

[0057] Specifically, such as Figure 3 As shown, in the initial position, the two separating plates 12 are located on both sides of the guide channel, and the push plate 15 is located above one of the guide plates 2. When the separating mechanism is working, as... Figure 4 As shown, the two first telescopic bars 11 drive the two separation plates 12 to approach each other, as... Figure 5As shown, the separating plates 12 have downward-sloping sections at their adjacent ends. These sections extend above the material guide channel and are inserted between the outer flanges of two adjacent plastic packaging caps 16, separating the upper plastic packaging caps 16 from the lower ones. Then, the horizontal pushing mechanism begins operation, and the second telescopic lever 14 pushes the push plate 15 to move left and right, as shown... Figure 6 As shown, the separated packaging caps are pushed out horizontally.

[0058] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
