An orientation feeding device for conical bottle caps

Abstract

This utility model discloses a directional feeding device for conical bottle caps, including a frame body, and a storage bin, a lifting and conveying assembly, a directional screening assembly, and a bottle cap output assembly mounted on the frame body. The lifting and conveying assembly outputs the bottle caps to be processed from the storage bin to the directional screening assembly. This utility model utilizes a centrifugal force-driven discharge hopper with two spaced-apart discharge track plates installed on the discharge track. A screening and conveying track is formed between the two discharge track plates. The width of the screening and conveying track is greater than the diameter of the top of the bottle cap but smaller than the diameter of the bottle cap body. This allows the bottle caps to be directly screened along the screening and conveying track as they pass through the discharge hopper, and then output according to the specified orientation. This achieves directional output of the bottle caps while shortening the screening path, thereby improving screening efficiency.

[0001] This utility model belongs to the technical field of bottle cap feeding equipment, specifically relating to a directional feeding device for conical bottle caps. Background Technology

[0002] In the automated bottling process of bottled beverages or alcoholic drinks, an automatic bottle cap feeder is required to automatically feed the bottle caps. When the automatic feeder feeds bottle caps that are wider at the top and narrower at the bottom (such as...), it is necessary to feed them automatically. Figure 1 When processing bottle caps (as shown), it is necessary to control the orientation of the bottle caps to facilitate subsequent processing.

[0003] Chinese patent publication number "CN210559269U" discloses an automatic feeding machine for capping machines. It includes a vibratory feeder for discharging bottle caps. The vibratory feeder is installed on top of a vibrator. The vibratory feeder has a slide for conveying bottle caps inside. A straight discharge pipe is connected to the discharge port of the vibratory feeder. An inclined conveying pipe is connected to the end of the straight discharge pipe. An arc-shaped conveying pipe for flipping bottle caps is connected to the end of the inclined conveying pipe. A clamping discharge mechanism for discharging bottle caps is installed at the end of the arc-shaped conveying pipe.

[0004] The aforementioned patent uses a vibratory feeder to achieve directional output of bottle caps. However, the vibratory feeder has a long vibration path, resulting in low feeding efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a directional feeding device for conical bottle caps, which solves the technical problems of long vibration paths and low feeding efficiency in existing vibration-type directional output devices.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A directional feeding device for conical bottle caps includes a frame body, and a bottle cap feeding assembly, a directional screening assembly, and a bottle cap output assembly mounted on the frame body. The bottle cap feeding assembly includes a storage bin and a lifting and conveying assembly. The lifting and conveying assembly outputs the bottle caps to be processed from the storage bin to the directional screening assembly.

[0007] The directional screening assembly includes a discharge bin and a screening track assembly. The top and side walls of the discharge bin are respectively provided with a feed inlet and a discharge outlet. A rotary output assembly is located at the bottom of the discharge bin, which uses centrifugal force to output the processed bottle caps entering the discharge bin one by one towards the discharge outlet.

[0008] The screening track assembly includes a discharge track. The input end of the discharge track is connected to the discharge port, and two spaced-apart discharge track plates are installed on the discharge track. A screening conveying track is formed between the two discharge track plates. The width of the screening conveying track is greater than the diameter of the top of the bottle cap being processed, but smaller than the diameter of the body of the bottle cap being processed.

[0009] Furthermore, the screening track assembly also includes a material discharge track. Two spaced-apart material discharge track plates are installed on the material discharge track. The gap between the two material discharge track plates forms a directional conveying track; the input end of the directional conveying track is connected to the output end of the screening conveying track.

[0010] Furthermore, a return port is provided on the discharge track. A return channel is installed at the return port. The output end of the return channel is connected to the storage bin.

[0011] Furthermore, the directional conveying track is divided into an entry section, a sliding section, and an output section. The entry section and the output section are respectively connected to the output end of the discharge track and the input end of the bottle cap output assembly. The sliding section has a vertical track structure.

[0012] Furthermore, a guide rod is provided at the discharge port of the discharge hopper.

[0013] Furthermore, the rotary output assembly includes a conical rotating material plate and a rotary motor. The rotating material plate is rotatably connected to the inner cavity of the discharge hopper. The rotary motor is fixed to the bottom of the discharge hopper, and its output shaft passes through the bottom surface of the discharge hopper and is fixed to the rotating material plate.

[0014] Furthermore, multiple pushing protrusions are fixed on the rotating material plate.

[0015] Furthermore, the bottle cap output assembly includes a conveyor bracket and an output conveyor belt. The conveyor bracket is fixed to the main frame. Limiting plates are fixed on both sides of the top of the conveyor bracket. The adjacent sides of the two limiting plates are spaced apart to form an output channel that mates with the bottle caps being processed. The output conveyor belt is disposed within the output channel.

[0016] Furthermore, the lifting and conveying assembly is divided into a bottom feeding end and a bottom discharging end. The feeding end extends into the bottom of the storage bin. The discharging end is located directly above the feed inlet in the discharge hopper.

[0017] Furthermore, the lifting and conveying assembly includes a lifting support, a feeding conveyor belt, and multiple partitions spaced apart on the feeding conveyor belt. The lifting support is inclined. The feeding conveyor belt is mounted on the lifting support, and its bottom extends into the storage bin.

[0018] Compared with the prior art, the present invention has the following advantages: This invention features two spaced-apart discharge track plates at the outlet of a centrifugal discharge hopper. These two tracks form a screening conveyor track. The width of the screening conveyor track is greater than the diameter of the top of the bottle cap being processed, but smaller than the diameter of the bottle cap body. This allows the bottle caps to be directly screened along the screening conveyor track as they pass through the discharge hopper, ensuring they are output in the designated orientation. This shortens the screening path while achieving directional output of the bottle caps, thereby improving screening efficiency. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the 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.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 2As shown, a directional feeding device for conical bottle caps includes a frame body 1, and a bottle cap feeding assembly 2, a directional screening assembly 3, and a bottle cap output assembly 4 mounted on the frame body 1. The bottle cap feeding assembly 2 includes a storage bin 5 and a lifting and conveying assembly 6. The lifting and conveying assembly 6 is used to output the bottle caps to be processed from the storage bin 5 to the directional screening assembly 3.

[0024] The directional screening assembly 3 includes a discharge bin 7 and a screening track assembly 8. The inlet is located at the top of the discharge bin 7. A discharge outlet is located on the side wall of the discharge bin 7. A rotatably connected rotary output assembly 9 is located at the bottom of the discharge bin 7, which uses centrifugal force to output the processed bottle caps one by one towards the discharge outlet. The screening track assembly 8 is installed at the discharge outlet for directional output of the processed bottle caps.

[0025] like Figure 3 and 5 As shown, the screening track assembly 8 includes a discharge track 10 and a drop track 11 connected in sequence. The discharge track 10 has two spaced-apart discharge track plates installed on it, forming a screening conveying track between the two plates. The drop track 11 has two spaced-apart drop track plates installed on it, forming a directional conveying track 12 between the two drop track plates.

[0026] In this embodiment, the width of the screening and conveying track is greater than the diameter of the top of the bottle cap being processed, but smaller than the diameter of the body of the bottle cap being processed. A return port 13 is provided at the bottom of the discharge track 10. A return channel 14 is installed at the return port 13. The output end of the return channel 14 is connected to the storage tank 5, allowing the bottle caps falling from the return port 13 to flow back into the storage tank 5.

[0027] During the directional conveying of the bottle caps being processed, when the bottle caps are in an inverted state with the cap body facing upwards and the cap top facing downwards, the diameter of the cap body is larger than the width of the screening conveyor track, allowing the bottle caps to be smoothly conveyed on the track. When the bottle caps are in an upright state with the cap top facing upwards and the cap body facing downwards, the diameter of the cap top is smaller than the width of the screening conveyor track, causing the bottle caps to fall from the return port on the discharge track 10 to the return channel 14 and flow back to the storage bin 5, thus achieving directional output of the bottle caps.

[0028] In this embodiment, the directional conveying track 12 is divided into an entry section, a sliding section, and an output section. The entry section and output section are connected to the output end of the discharge track 10 and the input end of the bottle cap output assembly 4, respectively. The sliding section has a vertical track structure. In actual use, when the bottle caps being processed, which are inverted, enter the entry section of the directional conveying track 12 one by one from the output end of the discharge track 10, the bottle caps at the front will be pushed towards the sliding section by the subsequent bottle caps. After entering the sliding section, the bottle caps will slide naturally under gravity and pass through the output section, being output towards the bottle cap output assembly 4.

[0029] Furthermore, such as Figure 4 As shown, a guide rod 15 is provided at the discharge port of the discharge bin 7 to guide the bottle caps to be processed, which are guided by the rotating output component 9 to the outer ring of the discharge bin 7, into the directional conveying track 12.

[0030] The rotary output assembly 9 includes a conical rotary material plate and a rotary motor. The rotary material plate is rotatably connected to the inner cavity of the discharge chamber 7. The rotary motor is fixed to the bottom of the discharge chamber 7, and its output shaft passes through the bottom surface of the discharge chamber 7 and is fixed to the rotary material plate, enabling it to drive the rotary material plate and the bottle caps being processed on the surface of the rotary material plate to rotate around the center.

[0031] Furthermore, multiple pushing protrusions are fixed on the rotating material plate. The pushing protrusions are evenly distributed around the axis of the rotating material plate to assist the bottle caps being processed on the rotating material plate in circumferential movement, ensuring that the bottle caps being processed can be smoothly output from the discharge port side of the discharge chamber 7.

[0032] The bottle cap output assembly 4 includes a conveyor bracket and an output conveyor belt. The conveyor bracket is fixed to the main frame 1. Limiting plates are fixed to both sides of the top of the conveyor bracket. The adjacent sides of the two limiting plates are spaced apart to form an output channel that mates with the bottle caps being processed. The input end of the output channel is connected to the output end of the positioning conveyor track, used to receive the bottle caps being oriented and output from the positioning conveyor track. The output conveyor belt is located within the output channel, used to drive the bottle caps being oriented and output from the positioning conveyor track outwards, facilitating the subsequent process of adding sealing gaskets to the bottle caps.

[0033] like Figure 6 As shown, in this embodiment, the lifting and conveying assembly 6 has two ends: a bottom feeding end and a bottom discharging end. The feeding end extends into the bottom storage area of ​​the storage bin 5. The discharging end is located directly above the inlet in the discharging hopper 7. The bottle caps being processed in the storage bin 5 are output one by one to the discharging hopper 7 via the lifting and conveying assembly 6 for directional output.

[0034] Specifically, the lifting and conveying assembly 6 includes a lifting bracket 16, a feeding conveyor belt 17, and multiple partitions 18 spaced apart on the feeding conveyor belt 17. The lifting bracket 16 is inclined. The feeding conveyor belt 17 is mounted on the lifting bracket 16, with its bottom extending into the storage bin 5. Driven by the partitions 18 on the feeding conveyor belt 17, it rises upwards to the inlet of the discharge bin 7.

[0035] like Figure 2 As shown, the storage bin 5 has a conical box structure that is wider at the top and narrower at the bottom, with an open top. Furthermore, a mounting slot is provided on one side wall of the storage bin 5. The two edges of the mounting slot are respectively fixed to the two side supports of the lifting bracket 16.

[0036] The working principle of this utility model is as follows: During actual processing, the feeding conveyor belt 17 operates, and the bottle caps 100 being processed in the storage bin 5 are lifted upwards by the partitions 18 on the feeding conveyor belt 17 until they fall into the discharge bin 7. The rotating plate in the discharge bin 7 rotates under the drive of the rotating motor. Under the action of centrifugal force, the bottle caps 100 being processed in the discharge bin 7 are output towards the discharge port side of the discharge bin 7 and enter the input end of the screening and conveying track.

[0037] When the bottle cap 100 is in an inverted state with the cap body facing up and the cap top facing down, the diameter of the cap body is larger than the width of the screening conveyor track, allowing the bottle cap 100 to be smoothly conveyed on the screening conveyor track. When the bottle cap 100 is in an upright state with the cap top facing up and the cap body facing down, the diameter of the cap top is smaller than the width of the screening conveyor track, causing the bottle cap 100 to fall from the return port 13 on the discharge track 10 to the return channel 14 and flow back to the storage box 5, thereby achieving directional output of the bottle cap 100.

[0038] The bottle caps 100 being processed, in an inverted state, enter the entry section of the directional conveying track 12 one by one from the output end of the discharge track 10. The bottle caps 100 at the front will be pushed towards the sliding section by the following bottle caps 100. After the bottle caps 100 enter the sliding section, they will slide down naturally under the action of gravity, pass through the output section, and be output towards the bottle cap output assembly 4, and then be conveyed to the subsequent processing device through the bottle cap output assembly 4.

[0039] Finally, it should be noted that 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.
