Description

Technical Field

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

[0002] The disposable plastic caps used for boxed ice cream are typically first compression molded, and then graphics and text are printed on the top of the molded cap. To ensure a stable connection between the ice cream box and the plastic cap, the plastic caps used for boxed ice cream have a downward-curving center and outward-flaring edges. The compression-molded caps are stacked together and then transferred to the printing equipment for individual printing. Before being fed into the printing equipment, the stacked plastic caps need to be separated one by one, and then fed into the printing equipment face up. Currently, this separation is mainly done manually, but the separation efficiency is low, and when the separated caps are fed into the printing equipment, the orientation of the plastic caps is easily reversed, affecting the processing efficiency of the plastic caps. Utility Model Content

The limiting rod is vertically installed in the mounting groove and passes through the feeding port. The limiting rod is connected to the horizontal plate. The multiple limiting rods form the material guiding channel, and the notch is formed between two adjacent limiting rods.

[0011] Furthermore, the aforementioned stacked plastic packaging cap separating device further includes:

[0025] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0030] 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.

[0031] 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. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Figures 1-4 A stacked plastic packaging cap separation device provided for an embodiment of this utility model includes:

[0033] A horizontal plate 1, on which a discharge port 2 is provided;

[0034] A material guide channel, which vertically penetrates the discharge port 2 and connects to the horizontal plate 1; the material guide channel includes:

[0035] The limiting rod 5 is provided with multiple mounting grooves on the inner wall of the feeding port 2. The limiting rod 5 is vertically provided in the mounting groove and passes through the feeding port 2. The limiting rod 5 is connected to the horizontal plate 1. The multiple limiting rods 5 form the material guiding channel, and the notch is formed between two adjacent limiting rods 5.

[0036] Two sets of left-right spaced separation components, each separation component including two vertically arranged rotating cylinders 3, the two rotating cylinders 3 are arranged at an interval below the horizontal plate 1, the rotating cylinders 3 are coaxially sleeved with threaded blades 4, the side wall of the material guide channel is provided with a notch corresponding to the threaded blades 4, the outer edge of the threaded blades 4 passes through the corresponding notch and extends into the material guide channel;

[0037] The drive mechanism is mounted on the horizontal plate 1 and is connected to the rotating drum 3 for transmission, so as to drive the rotating drum 3 to rotate synchronously. The two rotating drums 3 of the separation assembly rotate in opposite directions, and the spiral directions of the threaded blades 4 on them are opposite.

[0038] In this embodiment, the plastic packaging cap 13 is placed horizontally into the guide channel. The cross-sectional shape of the guide channel matches the shape of the plastic packaging cap 13 on the horizontal plane, limiting the stacked plastic packaging caps 13 so that they can only move vertically within the guide channel. The outer edges of the threaded blades 4 on the two rotating drums 3 of the separating assembly extend into the guide channel. When the outer flanges of the plastic packaging caps 13 extend into the threaded blades 4 of the four rotating drums 3 respectively, as... Figure 3 As shown, the plastic packaging cover 13 can be placed on the outer edge of the threaded blades 4 of each rotating drum 3, and the contact part between the outer flange of the plastic packaging cover 13 and the threaded blades 4 is on the same horizontal plane, forming a support surface. The two rotating drums 3 of the same separating assembly rotate in opposite directions, and the spiral directions of the threaded blades 4 on them are opposite. When the two rotating drums 3 rotate synchronously, under the limit of the guide channel, the contact part between the two threaded blades 4 and the outer flange of the plastic packaging cover 13 will move up and down, forming a lifting part. The two sets of separating assemblies form two lifting parts, which can drive the plastic packaging cover 13 to move up and down in the guide channel.

[0039] like Figure 1 and Figure 2As shown, in the initial state, the outer flange of the first plastic packaging cap 13 at the bottom rests on the outer edge of the threaded blades 4 of each rotating drum 3. As each rotating drum 3 rotates, the plastic packaging cap 13 moves downward until the outer flange of the first plastic packaging cap 13 at the bottom separates from the threaded blades 4. At this time, the second plastic packaging cap 13 at the bottom descends and rests on the outer edge of the threaded blades 4. Under the action of gravity, the first plastic packaging cap 13 at the bottom will separate from the second plastic packaging cap 13 at the bottom, thus being separated from the stacked plastic packaging caps 13. A conveying mechanism is set below the separation device to transport the separated plastic packaging caps 13 away. As the rotating drum 3 rotates, the stacked plastic packaging caps 13 will be separated one by one, thus realizing the separation of multiple stacked plastic packaging caps 13 one by one.

One of the limiting rods 5 is configured as an upper rod 51, a middle rod 52, and a lower rod 53. The upper rod 51 and the lower rod 53 are fixed to the connecting plate 6 and the horizontal plate 1, respectively. The upper and lower ends of the middle rod 52 are detachably connected to the upper rod 51 and the lower rod 53, respectively. This allows the middle rod 52 to be removed during material loading, the stacked plastic packaging caps 13 to be vertically placed into the guide channel, and finally the middle rod 52 to be reinstalled. Specifically, the upper and lower ends of the middle rod 52 are provided with connecting parts 7, and the connecting parts 7 are provided with grooves. When the middle rod 52 is connected to the upper rod 51 and the lower rod 53, the upper rod 51 and the lower rod 53 are respectively embedded in the two grooves, thereby realizing the connection between the upper and lower ends of the middle rod 52 and the upper rod 51 and the lower rod 53, respectively.
