Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a feeding mechanism for an inner cover of a cosmetic bottle, which solves the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A feeding mechanism for inner caps of cosmetic bottles, comprising the inner caps of the bottles being wide at the top and narrow at the bottom, wherein arc axes recessed inwards are symmetrically opened on both sides of the upper part of the inner caps, and two ends of one arc axis are located on the same horizontal plane and correspond to each other in the front and back, comprising a feeding machine for conveying the inner caps of the bottles, a vibrating plate located at the lower end of the discharge port of the feeding machine, and a conveying channel provided at the discharge port of the vibrating plate;

[0008] The vibration plate comprises a lower vibration area, an upper conveying channel and an outward conveying channel;

[0009] The lower vibration zone receives the inner caps of the bottles conveyed upward by the feeding machine and performs vibration.

[0010] The front end of the upper conveying channel is connected to the lower vibration zone and one end of the bottle inner cap is conveyed upward, and the upper conveying channel gradually narrows from the front end; the end of the upper conveying channel is bent inward toward one side of the lower vibration zone;

[0011] One side of the front end of the outward conveying channel is connected to the end of the upper conveying channel, and a gap is formed between the other side of the front end and the inward bending portion of the end of the upper conveying channel;

[0012] A left guide rail and a right guide rail are provided at the middle and rear ends of the upper conveying channel; the left guide rail extends from the upper conveying channel to the gap; and the right guide rail extends from the upper conveying channel into the outer conveying channel.

[0013] Optionally, a first scraper is provided at the front end of the upper conveying channel, and the lower surface of the first scraper is spaced from the inner bottom wall of the upper conveying channel by the height of an inner cap of a bottle.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0027] In the description of the present invention, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "up", "down", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "end", "head" and "tail" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solution of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] The present application proposes a cosmetic bottle inner cover feeding mechanism, which is specifically as follows:

[0029] For reference Figure 1-2 The present application is mainly composed of a feeder 2 for conveying bottle inner caps 1, a vibrating plate 3 located at the lower end of the discharge port of the feeder 2, and a conveying channel 4 provided at the discharge port of the vibrating plate 3; thereby, a large number of bottle inner caps 1 can be conveyed in the required direction, thereby increasing the convenience of subsequent processing procedures.

[0030] For reference Figure 1-2 In the present application, it is used to convey the bottle inner cap 1. Based on the shape of the bottle inner cap 1, the overall feeding mechanism is set to do relative movement; the bottle inner cap 1 is generally wide at the top and narrow at the bottom, the lower part of which is a threaded cylinder, and the upper part is set as a dome coaxial with the lower part. The setting of the dome is not a complete circle, and the two sides of the dome are symmetrically provided with arc axes recessed inward, and the two side edges of one arc axis are correspondingly located on the same horizontal plane front and back, and the arc axes on both sides are set in the same shape.

[0031] For reference Figure 1-2 In this application, the finished bottle inner cap 1 is first poured into the feeder 2; the feeder 2 is directed toward the vibration plate 3 on the lower side to do the feeding work; the feeder 2 is an existing device for conveying materials with a timed switch, which is a relatively mature technology in the existing market, and this application will not go into details.

[0032] For reference Figure 1-4 The vibration plate 3 is used to receive the material transmitted from the feeder 2, wherein the vibration plate 3 includes a lower vibration zone 31, an upper conveying channel 32 and an outward conveying channel 33; the lower vibration zone 31 receives the bottle inner cap 1 conveyed upward by the feeder 2 to perform vibration work, and this part is a structure that most existing vibration plates have, and this application will not elaborate on it. The front end of the upper conveying channel 32 is connected to the lower vibration zone 31 to convey one end of the bottle inner cap 1 upward, and the bottle inner cap 1 is conveyed from the lower vibration zone 31 to the upper conveying channel 32 through vibration and rotation; wherein the upper conveying channel 32 gradually narrows from the front end, thereby causing the bottle inner cap 1 to move from parallel movement to vertical movement when moving on the upper conveying channel 32; at the same time, due to the setting of the arc axis in the bottle inner cap 1, the bottle inner cap 1 will be caused to turn as a whole, and the two ends of the arc axis are connected to the inner bottom wall of the upper conveying channel 32 to form a support, so that during the movement of the upper conveying channel 32, there will be no forward rolling.

[0033] It should be noted that in order to reduce the occurrence of overlapping during movement, a first scraper 6 is provided at the front end of the upper conveying channel 32, and the lower surface of the first scraper 6 is at a height of one bottle inner cap 1 away from the inner bottom wall of the upper conveying channel 32; thus, when the bottle inner cap 1 enters the upper conveying channel 32, the first scraper 6 will scrape off the overlapping bottle inner cap 1 on the upper part of the lowermost bottle inner cap 1.

[0034] The upper conveying channel 32 is located at the channel behind the first scraper 6 and is provided with an inner plate 323. An increasingly narrow channel is formed between the inner plate 323 and the outer wall of the vibration plate 3. The inner plate 323 is flush with the bottom plate from the starting point and gradually rises to the end to form a slope. When the bottle inner cap 1 enters from the starting point of the inner plate 323, the bottle inner cap 1 presents an opening horizontally facing upward or horizontally facing downward; when the vibration plate 3 continuously vibrates and moves forward, one side of the bottle inner cap 1 is gradually lifted by the slope of the inner plate 323 and moves toward the narrow place; when the bottle inner cap 1 enters from the starting point of the inner plate 323, ... inner plate 323 and moves toward the narrow place When the cap 1 passes through the narrow part of the upper conveying channel 32, the opening of the inner cap 1 becomes lateral; specifically, the inner cap 1, which previously opened horizontally upward, becomes open outward, and the center of gravity relies on the outer wall and continues to move along the right guide rail 322; the inner cap 1, which previously opened horizontally downward, becomes open inward, and the center of gravity relies on the inner plate 323, and the end of the inner plate 323 bends inward toward one side of the lower vibration zone 31, and the inner cap 1 will fall down from the gap 5 to the bottom of the lower vibration zone 31 under the guidance of the left guide rail 321 and reflux. The above process completes the screening of the orientation of the inner cap 1.

[0035] When the upper part of the bottle inner cap 1 is located on the right side, it will enter the outward conveying channel 33 along the right guide rail 322, wherein the other side of the front end of the outward conveying channel 33 is connected to the end of the upper conveying channel 32, which can support the bottle inner cap 1 to enter the outward conveying channel 33 along the right guide rail 322; at the same time, the outward conveying channel 33 gradually widens from the front end, but the distance between the right guide rail 322 and the right end of the outward conveying channel 33 is unchanged; the constraint of the right guide rail 322 on the bottom of the bottle inner cap 1 and the relaxation of the widened outward conveying channel 33 on the upper part of the bottle inner cap 1 cause the opening of the bottle inner cap 1 to gradually tilt from toward the outside until the opening is horizontally facing upward. At this time, the upper part of the bottle inner cap 1 moves upward until it is transferred to the conveying channel 4.

[0036] When transferring into the conveying channel 4, in order to avoid the inner caps 1 being stacked again, a second scraper 7 is arranged at the end of the outward conveying channel 33, and the second scraper 7 performs a screening work again;

[0037] At the same time, in order to prevent the bottle inner cap 1 from moving upward and being higher than the conveying channel 4 due to obstacles in the conveying channel 4 during transportation, baffles 8 are provided at both ends of the upper side of the conveying channel 4. There is a gap between the baffles 8, and the gap is smaller than the width of the conveying channel 4; the bottle inner cap 1 can be effectively prevented from falling out of the conveying channel 4 when moving.

[0038] In the utility model, the working steps of the device are as follows:

[0039] 1. First, pour the bottle inner cap 1 into the feeder 2, and the feeder 2 pours the bottle inner cap 1 into the vibration plate 3 facing downward at a fixed time and quantity;

[0040] 2. Secondly, when the vibration plate 3 is working, it first performs vibration and rotation work through the lower vibration zone 31, and then enters the upper conveying channel 32 to convert the horizontally moving bottle inner cap 1 into a vertically moving state;

[0041] 3. Then, through the left guide rail 321 and the right guide rail 322 provided at the end of the upper conveying channel 32, the bottle inner cap 1 moves along the left guide rail 321 or the right guide rail 322 according to the orientation of the bottle inner cap 1;

[0042] 4. Finally, driven by the left guide rail 321 and the right guide rail 322, the bottle inner cap 1 is prompted to fall from the gap or enter the outward conveying channel 33. When the bottle inner cap 1 enters the outward conveying channel 33, it will change with the width of the outward conveying channel 33, and the upper part of the bottle inner cap 1 will move upward and horizontally until it enters the conveying channel 4.

[0043] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
