Description

TECHNICAL FIELD

[0001] The utility model relates to bottle cap dust removal technical field, concretely relates to a bottle cap dust removal device. BACKGROUND

[0002] In the field of liquor and beverage production, filling and packaging is a common packaging method, and the container bottle needs to be sealed by using a bottle cap after filling. As a part of filling and packaging, the bottle cap has two main functions: one is sealing, which protects the product in the container bottle, and this is the most basic function of the bottle cap; the other is aesthetics, as an integral part of filling and packaging, the bottle cap can play a role in adding the finishing touch. The bottle cap will go through several production processes in the production process, so it is inevitable to be contaminated with dust. In order to ensure the cleanliness of the product, the bottle cap needs to be dusted before being used to seal the container bottle. The traditional bottle cap dusting method is manual dusting, which has the problems of low efficiency and incomplete dusting.

[0003] Therefore, the prior art (utility model patent with authorization announcement number CN201189519Y) discloses a bottle cap full-automatic electrostatic dust removal machine, which comprises a dust removal chamber, a slide that penetrates the outside and the inside is arranged at the entrance of the dust removal chamber, the slide is connected with a conveying belt outside, the arranged bottle caps enter the slide connected with the conveying belt under the pushing of the conveying belt, and then enter the dust removal chamber through the slide, a cap locking device for controlling the movement of the following bottle caps is arranged at the entrance of the dust removal chamber, an inductive probe is arranged inside the dust removal chamber, and a cap locking device for controlling the movement of the bottle caps in the dust removal chamber is arranged at the position corresponding to the inductive probe, and an upper blowing device and an electrostatic nozzle and fork are arranged at the upper and lower parts of the slide respectively and correspond to the bottle caps.

[0004] Although the above-mentioned prior art can realize automatic dust removal of the bottle cap, the following problems still exist in actual use: in order to improve the overall aesthetics of the filling and packaging, some bottle caps are designed to have a large head size and a small body size, the blowing device of the prior art is arranged at the upper part of the slide, and the dust on the outside of the bottle cap is removed by blowing from top to bottom, since the large head size of the bottle cap will shield the small body size, the dust removal of the body of the bottle cap is incomplete or even impossible, which reduces the overall dust removal effect of the bottle cap and makes it difficult to meet the subsequent production requirements.

[0005] Therefore, there is an urgent need for a bottle cap dust removal device to remove dust from the outside of the bottle cap to meet the dust removal requirements of the bottle cap with a large head size and a small body size. UTILITY MODEL CONTENTS

[0006] The utility model intends to provide a bottle cap dust removal device to solve the technical problem that the prior art blows from top to bottom to remove dust from the outside of the bottle cap, which is difficult to meet the dust removal requirements of the bottle cap with a large head size and a small body size.

[0007] To achieve the above object, the utility model discloses the following technical scheme:

[0008] A bottle cap dust removal device is arranged on a bottle cap conveying device and comprises a dust removal cover, a blowing mechanism and a dust suction mechanism.

[0009] The principle and advantages of the present application are as follows:

[0010] In actual application, the bottle cap conveying device passes through the dust removal cover, and the bottle cap conveyed by the bottle cap conveying device passes through the top blowing assembly and the side blowing assembly when passing through the dust removal cover.

[0011] 1. The blowing mechanism comprises a top blowing assembly and a side blowing assembly, the top blowing assembly blows from top to bottom to remove dust on the top of the bottle cap, and the side blowing assembly blows from both sides to remove dust on the side wall of the bottle cap.

[0012] 2. Even if the present application is applied to the dust removal treatment of ordinary bottle caps with similar head size and body size, it can achieve better dust removal effect compared to the existing technology that only blows from top to bottom.

[0013] 3. In this solution, the top blowing component and the side blowing component of the blower mechanism are alternately set along the direction perpendicular to the bottle cap conveying direction, and the blowing components near the two side walls of the dust removal hood are all set as side blowing components. When the bottle cap conveying device conveys one or more bottle caps side by side, it can ensure that each bottle cap conveyed side by side is equipped with a side blowing component, thereby ensuring that each bottle cap conveyed side by side is blown by air, which is conducive to improving the consistency of dust removal effect of each bottle cap.

[0014] 4. This solution is equipped with several suction pipes connected to an external vacuum cleaner. When the blower mechanism blows air to remove dust from the bottle caps, the suction pipes will suck up the dust blown off the bottle caps in real time. This can prevent dust from remaining in the dust hood and contaminating the dust removal device, the bottle cap conveying device, and the bottle caps that are subsequently conveyed, thus helping to keep the equipment clean and reducing the difficulty of dust removal for the bottle caps that are subsequently conveyed. It can also prevent dust from flying into the working environment through the gap between the dust hood and the bottle cap conveying device, which is beneficial to the health of the staff.

[0015] Preferably, as an improvement, the side-blowing assembly includes a ventilation duct and several side-blowing pipes. The ventilation duct is connected to an external air source, and the length direction of the ventilation duct is parallel to the bottle cap conveying direction. Several side-blowing pipes are spaced apart along the length direction of the ventilation duct. The top of the side-blowing pipe is connected to the ventilation duct, the bottom of the side-blowing pipe is sealed, and the sidewall of the side-blowing pipe has several side-blowing holes facing the bottle cap along its own length direction.

[0016] Beneficial effects: This solution involves setting up several side blowing pipes at intervals along the bottle cap conveying direction. During the process of conveying the bottle caps inside the dust removal hood, the side walls of the bottle caps can be blown and dusted multiple times through these side blowing pipes, which helps to improve the dust removal effect on the side walls of the bottle caps. Furthermore, several side blowing holes facing the bottle caps are opened along the length of the side blowing pipes, that is, several side blowing holes are opened along the height direction on the side blowing pipes. On the one hand, this can meet the dust removal needs of bottle caps with different heights. On the other hand, the air blown out by the side blowing holes at higher positions can sweep the top of the bottle caps horizontally, further improving the dust removal effect on the top of the bottle caps.

[0017] Preferably, as an improvement, the top-blowing assembly includes a top-blowing air pipe arranged parallel to the ventilation duct, the top-blowing air pipe being connected to an external air source, and the bottom of the top-blowing air pipe having a plurality of top-blowing air holes facing the bottle cap along its length.

[0018] Beneficial effects: This solution involves opening several top-blowing holes at the bottom of the top-blowing pipe along the bottle cap conveying direction, which face the bottle cap. During the process of conveying the bottle cap inside the dust removal hood, the top of the bottle cap can be blown from top to bottom multiple times through these top-blowing holes, which helps to improve the dust removal effect on the top of the bottle cap.

[0019] Preferably, as an improvement, the top blowing pipe is located directly above the bottle cap, and the top blowing hole is vertically arranged; the side blowing pipe is vertically arranged, and the side blowing hole is horizontally arranged.

[0020] Beneficial effects: The top blowing pipe is arranged directly above the bottle cap, and the top blowing hole is vertically arranged, which can ensure that the air blown from the top blowing hole is vertically blown on the center of the top of the bottle cap, thereby further improving the dust removal effect of the top of the bottle cap; the side blowing pipe is vertically arranged, and the side blowing hole is horizontally arranged, as long as the side wall of the bottle cap is vertically arranged, the air blown from the side blowing hole can be vertically blown on the side wall of the bottle cap, thereby further improving the dust removal effect of the side wall of the bottle cap. In addition, the position of the top blowing pipe and the side blowing pipe, and the opening direction of the top blowing hole and the side blowing hole, are all conducive to improving the convenience of processing and installation of the dust removal device.

[0021] Preferably, as an improvement, one or more of the ventilation pipe, the side blowing pipe and the top blowing pipe is a square pipe.

[0022] Beneficial effects: One or more of the ventilation pipe, the side blowing pipe and the top blowing pipe is a square pipe, which can be more convenient for punching, installation and other positioning operations, thereby improving the efficiency of early processing and on-site installation.

[0023] Preferably, as an improvement, the side blowing pipe is a square pipe, and the side wall of the side blowing pipe is perpendicular or parallel to the conveying direction of the bottle cap.

[0024] Beneficial effects: The side blowing pipe is a square pipe, which not only facilitates the positioning and punching of the side blowing hole on the side blowing pipe, but also facilitates the positioning and connection of the side blowing pipe to the ventilation pipe. Furthermore, the side wall of the side blowing pipe is perpendicular or parallel to the conveying direction of the bottle cap, so that the side blowing hole can be vertically arranged on the side wall of the side blowing pipe parallel to the conveying direction of the bottle cap, so that the axis of the side blowing hole is perpendicular to the conveying direction of the bottle cap, thereby ensuring that the air blown from the side blowing hole is vertically blown on the side wall of the bottle cap, thereby ensuring the dust removal effect of the side wall of the bottle cap.

[0025] Preferably, as an improvement, the side blowing pipe of the side blowing assembly located on both sides has a side blowing hole only on one side wall of the bottle cap; the side blowing pipe of the side blowing assembly located in the middle has a side blowing hole on both side walls of the bottle cap.

[0026] Beneficial effects: The side blowing assembly located in the middle has side blowing holes opened on both side walls of the side blowing pipe close to the bottle cap, so that the side blowing pipe can blow air from the side blowing holes on both sides to blow and clean the bottle caps on both sides. Compared with the mode of setting two side blowing assemblies with opposite blowing directions to blow and clean the bottle caps on both sides, the device structure can be simplified, and the structure is more simple and efficient. The side blowing assemblies located on both sides have side blowing holes opened on only one side wall of the side blowing pipe close to the bottle cap, so that the waste of air source can be avoided.

[0027] Preferably, as an improvement, the side blowing pipe is a square pipe, and the angle between any side wall of the side blowing pipe and the conveying direction of the bottle cap is 45°.

[0028] Beneficial effects: The side blowing pipe is set as a square pipe, which is convenient for positioning and punching the side blowing holes on the side blowing pipe and connecting the side blowing pipe to the ventilation pipe. The angle between any side wall of the side blowing pipe and the conveying direction of the bottle cap is 45°, which can meet the needs of multi-directional hole opening and blowing and cleaning, is more convenient for positioning compared with other angles, and ensures the convenience of installation.

[0029] Preferably, as an improvement, the side blowing assemblies located on both sides have side blowing holes opened on only one side wall of the side blowing pipe close to the bottle cap and towards the inside of the dust removal hood, and the side blowing pipe located in the middle has side blowing holes opened on both side walls close to the bottle cap. The side blowing assemblies located in the middle have side blowing holes opened on both side walls of the side blowing pipe close to the bottle cap and towards the inside of the dust removal hood.

[0030] Beneficial effects: The side blowing assemblies located on both sides have side blowing holes opened on only one side wall of the side blowing pipe close to the bottle cap and towards the inside of the dust removal hood, so that the dust falling from the bottle cap is not blown to the external environment by the side blowing pipes on both ends blowing air to the outside of the dust removal hood, and the working environment is kept clean. The side blowing pipe located in the middle has side blowing holes opened on both side walls close to the bottle cap, so that the bottle cap side walls can be blown and cleaned in multiple directions, and the dust removal effect of the bottle cap side walls is improved. The side blowing pipes of the side blowing assemblies located on both sides do not have side blowing holes opened on the side walls close to the dust removal hood, so that the waste of air source is avoided.

[0031] Similarly, the side blowing assemblies located in the middle have side blowing holes opened on both side walls of the side blowing pipe close to the bottle cap and towards the inside of the dust removal hood, so that the dust falling from the bottle cap is not blown to the external environment by the side blowing pipes on both ends blowing air to the outside of the dust removal hood, and the working environment is kept clean. The side blowing pipe located in the middle has side blowing holes opened on all four side walls, so that the bottle cap side walls can be blown and cleaned in multiple directions, and the dust removal effect of the bottle cap side walls is improved.

[0032] Overall, the scheme can blow and clean the side wall of the bottle cap from four uniform directions, compared with the way of blowing and cleaning from two sides of the bottle cap, the wind direction of side blowing is increased, the dead angle of the side blowing to the side wall of the bottle cap is reduced or even avoided, and the dust removal effect of the side wall of the bottle cap can be further improved.

[0033] Preferably, as an improvement, the dust suction mechanism is symmetrically distributed on the two sides of the dust removal cover.

[0034] Beneficial effects: the scheme symmetrically distributes several dust suction pipes on the two sides of the dust removal cover, which can improve the dust suction uniformity of the dust suction mechanism on the inside of the dust removal cover, ensure that the dust blown from the bottle cap to each part inside the dust removal cover is timely sucked away, and avoid the pollution of the dust removal device, the bottle cap conveying device and the subsequent conveying bottle cap.

In this embodiment, the bottle cap conveying device is prior art, such as a bottle cap cleaning and dust removal device disclosed in the applicant's prior utility model patent application (authorization announcement number CN218835418U), in which the feeding device is the bottle cap conveying device referred to in this embodiment. Its structure and principle are prior art, and will not be described in detail in this embodiment.

[0047] A bottle cap dust removal device, as shown in the attached Figures 1-4 As shown, the device includes a dust hood 1, a blower mechanism, and a dust collection mechanism. The dust hood 1 is U-shaped and covers the top of the bottle cap conveying device. Specifically, the dust hood 1 includes a horizontally arranged top plate 11 and side plates 12 vertically connected to the bottom sides of the top plate 11. The top plate 11 and the side plates 12 are welded together or integrally formed. Several strip holes 13 are provided near the bottom of the side plates 12. During installation, bolts or other connectors are used to pass through the strip holes 13 to fix the dust hood 1 to the bottle cap conveying device. In this embodiment, baffles 14 are welded together or integrally formed at both ends of the dust hood 1. The baffles 14 are U-shaped. The baffles 14 can reduce the gap between the dust hood 1 and the bottle cap conveying device, thereby reducing the overflow of dust from the dust hood 1.

[0048] The blower mechanism includes several top-blowing components 2 and several side-blowing components 3 disposed within the dust collection hood 1. The top-blowing components 2 and side-blowing components 3 are alternately arranged along a direction perpendicular to the bottle cap conveying direction, and the side-blowing components 3 are located closest to the two side plates 12 of the dust collection hood 1. The distance between two adjacent side-blowing components 3 is greater than the maximum diameter of the bottle cap. In this embodiment, there are two top-blowing components 2 and three side-blowing components 3, with the top-blowing components 2 located exactly in the middle of two adjacent side-blowing components 3.

[0049] The side blowing assembly 3 comprises a ventilation pipe 31 and a plurality of side blowing pipes 32, the length direction of the ventilation pipe 31 is parallel to the conveying direction of the bottle cap, and the plurality of side blowing pipes 32 are arranged at intervals along the length direction of the ventilation pipe 31. The ventilation pipe 31 is fixedly connected to the bottom of the top plate 11 of the dust removal cover 1 and communicates with an external air source. Specifically, both ends of the ventilation pipe 31 are sealed, and a side blowing connector 33 is communicated with the ventilation pipe 31 at a position close to both ends of the top of the ventilation pipe 31. The side blowing connector 33 extends out of the dust removal cover 1 and communicates with the external air source through a hose. The top of the side blowing pipe 32 is fixedly connected to the bottom of the ventilation pipe 31 and communicates with the ventilation pipe 31, and the bottom of the side blowing pipe 32 is sealed. A plurality of side blowing holes 34 are formed in the side wall of the side blowing pipe 32 along the length direction of the side blowing pipe 32 and face the bottle cap.

[0050] The top blowing assembly 2 comprises a top blowing pipe 21 arranged in parallel with the ventilation pipe 31. The top blowing pipe 21 is fixedly connected to the bottom of the top plate 11 of the dust removal cover 1 and communicates with an external air source. Specifically, both ends of the top blowing pipe 21 are sealed, and a top blowing connector 22 is communicated with the top blowing pipe 21 at a position close to both ends of the top of the top blowing pipe 21. The top blowing connector 22 extends out of the dust removal cover 1 and communicates with the external air source through a hose. A plurality of top blowing holes 23 are formed in the bottom of the top blowing pipe 21 along the length direction of the top blowing pipe 21 and face the bottle cap. In this embodiment, the top blowing pipe 21 is located directly above the bottle cap, and the top blowing holes 23 are vertically formed. The side blowing pipe 32 is vertically arranged, and the side blowing holes 34 are horizontally formed.

[0051] In this embodiment, the ventilation pipe 31, the side blowing pipe 32 and the top blowing pipe 21 are all square pipes, and the side wall of the side blowing pipe 32 is perpendicular or parallel to the conveying direction of the bottle cap. The side blowing pipe 32 of the side blowing assembly 3 located on both sides (i.e., the side blowing assembly 3 close to the side plates 12 of the dust removal cover 1) has side blowing holes 34 only on one side wall close to the bottle cap. The side blowing pipe 32 of the side blowing assembly 3 located in the middle has side blowing holes 34 on both side walls close to the bottle cap.

[0052] The dust suction mechanism comprises a plurality of dust suction pipes 4. One end of the dust suction pipe 4 communicates with the dust removal cover 1, and the other end of the dust suction pipe 4 communicates with an external dust collector. In this embodiment, the dust suction mechanism comprises two dust suction pipes 4, and the two dust suction pipes 4 are symmetrically distributed on both sides of the dust removal cover 1 and communicate with the side plates 12 of the dust removal cover 1.

[0053] The specific implementation process is as follows:

[0054] The bottle cap conveying device transports two bottle caps side-by-side through the dust collection hood 1. After entering the dust collection hood 1, the two bottle caps are positioned directly below the two top-blowing components 2, with two adjacent side-blowing components 3 located on either side of the corresponding bottle caps. An external air source delivers dust-collecting gas to the top-blowing duct 21 of the top-blowing component 2 via a hose. The dust-collecting gas is blown downwards through the top-blowing holes 23 onto the top of the bottle caps to remove dust. Simultaneously, an external air source delivers dust-collecting gas to the ventilation duct 31 and side-blowing duct 32 of the side-blowing component 3 via a hose. The dust-collecting gas is blown from both sides through the side-blowing holes 34 onto the side walls of the bottle caps to remove dust. The external vacuum cleaner starts synchronously with the external air source, blowing the dust from the top and side walls of the bottle cap into the dust removal hood 1 and simultaneously sucking it away. This prevents dust from remaining in the dust removal hood 1 and contaminating the bottle cap conveying device, the bottle cap dust removal device, and the bottle caps that are subsequently conveyed. It also prevents dust from overflowing from the gap between the dust removal hood 1 and the bottle cap conveying device.

[0055] This solution uses top-blowing component 2 and side-blowing component 3 to blow air onto the top and side walls of the bottle cap for dust removal. It can be applied to the external dust removal of ordinary bottle caps with similar head and body sizes, as well as bottle caps with large head and small body sizes. It has a wide range of applications and good dust removal effect.

[0056] Example 2

[0057] A bottle cap dust removal device, as shown in the attached Figures 5-8 As shown, the difference between this and Embodiment 1 is that: the dust collector hood 1 has baffles 14 welded or integrally formed at both ends. The baffles 14 are M-shaped, and notches 15 are provided on the baffles 14 corresponding to the ventilation duct 31 and the top blowing pipe 21, so that the ventilation duct 31 and the top blowing pipe 21 can be connected to the external air source. A connecting plate 16 is welded or integrally formed on the bottom of the baffles 14 near the side plate 12 of the dust collector hood 1. A connecting groove 17 is provided on the connecting plate 16. During installation, bolts or other connecting parts are used to pass through the connecting groove 17 to fix the baffles 14 to the bottle cap conveying device, thereby fixing the dust collector hood 1 to the bottle cap conveying device.

[0058] Compared to the U-shaped baffle 14 in Embodiment 1, the M-shaped baffle 14 in this embodiment can further reduce the gap between the dust hood 1 and the bottle cap conveying device, thereby further reducing the overflow of dust from the dust hood 1.

[0059] Both ends of the ventilation duct 31 are connected to side-blowing connectors 33. The side-blowing connectors 33 extend from inside the dust collector 1 through the notch 15 opened on the baffle 14 and are connected to an external air source through a hose. Both ends of the top-blowing duct 21 are connected to top-blowing connectors 22. The top-blowing connectors 22 extend from inside the dust collector 1 through the notch 15 opened on the baffle 14 and are connected to an external air source through a hose.

[0060] The included angle between any side wall of the side blowing pipe 32 and the conveying direction of the bottle cap is 45°. The side blowing assembly 3 located at the two sides (i.e. the side blowing assembly 3 close to the two side plates 12 of the dust removal hood 1) has the side blowing pipe 32 at the two ends only open the side blowing holes 34 on one side wall close to the bottle cap and towards the inside of the dust removal hood 1, and the side blowing pipe 32 at the middle part open the side blowing holes 34 on the two side walls close to the bottle cap. The side blowing assembly 3 located at the middle part has the side blowing pipe 32 at the two ends only open the side blowing holes 34 on the two side walls towards the inside of the dust removal hood 1, and the side blowing pipe 32 at the middle part open the side blowing holes 34 on the four side walls.

[0061] The embodiment can blow and clean the side wall of the bottle cap from four uniform directions. Compared with the embodiment 1 which only blows and cleans the bottle cap from two sides, the embodiment increases the blowing direction of the side blowing, reduces or even avoids the blowing dead angle of the side blowing to the side wall of the bottle cap, and can further improve the cleaning effect of the side wall of the bottle cap.

[0062] The above is only the embodiment of the present application, and the well-known specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
