Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle cap dust removal technology, and more specifically, to a bottle cap dust removal device. Background Technology
[0002] In the product packaging process, laser marking is commonly used to mark the required information on bottle caps, such as production date, batch number, and shelf life. However, during the laser marking process, the laser acts on the surface of the bottle cap, and due to factors such as the material of the bottle cap and the operating principle of the equipment, bottle cap dust is generated during laser marking and adheres to the surface of the bottle cap.
[0003] OCR inspection equipment is used to detect the presence and correctness of markings on bottle caps. If the bottle cap surface is covered with dust, the OCR inspection equipment will not be able to collect clear marking information on the bottle cap. The system will regard these unidentifiable bottle caps as abnormal products and automatically reject them, resulting in a large number of incorrect rejections, causing unnecessary product losses, production line disorder, affecting the schedule, and reducing production efficiency. Utility Model Content
[0004] The present invention aims to provide a bottle cap dust removal device to solve the problem in the prior art where bottle cap dust is generated during laser marking printing and adheres to the bottle cap surface, affecting subsequent detection and identification, resulting in product rejection errors, production line disorder, and impact on the schedule.
[0005] This utility model is achieved using the following technical solution: This utility model provides a bottle cap dust removal device, including a connecting and fixing bracket arranged on one side of a conveying mechanism for placing products; a dust removal brush and a blowing nozzle are installed on the connecting and fixing bracket, the blowing nozzle is connected to an air source through an air supply pipe, the dust removal brush and the blowing nozzle are arranged side by side, the bristles of the dust removal brush can contact the bottle cap of the product, and there is a gap between the blowing nozzle and the bottle cap; The distance between the dust removal brush and the starting end of the conveying mechanism is less than the distance between the blowing nozzle and the starting end of the conveying mechanism.
[0006] The conveying mechanism has a starting end and a tail end, and the conveying direction of the conveying mechanism is from the starting end to the tail end. The distance between the dust removal brush and the starting end of the conveying mechanism is less than the distance between the blowing nozzle and the starting end of the conveying mechanism. This ensures that during the process of the conveying mechanism transporting the product, the product will first come into contact with the dust removal brush, and the dust removal brush will gently brush over the product bottle cap, sweeping away the dust on the bottle cap, loosening the dust adhering to the surface of the bottle cap, reducing adhesion, and then the dust on the bottle cap will be blown away by the blowing nozzle.

[0011] As a preferred technical solution: The connecting and fixing bracket includes a vertical rod and a horizontal rod, the horizontal rod is connected to the upper end of the vertical rod, and the dust removal brush and the blower nozzle are connected to the horizontal rod.
[0012] As a preferred technical solution: The vertical bar and the horizontal bar are connected by a cross-shaped clamp connecting block.
[0013] As a preferred technical solution: The cross-shaped clamp connecting block has a horizontal locking hole and a vertical locking hole. Each of the horizontal and vertical locking holes has an opening on one side. One end of the vertical rod is inserted into the vertical locking hole, and the opening of the vertical locking hole is locked by assembling a locking member on the cross-shaped clamp connecting block. One end of the horizontal rod is inserted into the horizontal locking hole, and the opening of the horizontal locking hole is locked by assembling a locking member on the cross-shaped clamp connecting block, thereby fixing the vertical rod and the horizontal rod to the cross-shaped clamp connecting block.
[0014] As a preferred technical solution: The locking component can be a locking bolt, which is installed in the locking hole on the cross clamp connecting block.
[0015] As a preferred technical solution: The dust removal brush and the blowing nozzle are connected to the crossbar by a connector.
[0016] As a preferred technical solution: The connector uses clamping blocks, and two clamping blocks are installed on the crossbar. Each clamping block has a clamping hole, and one side of the clamping hole has an opening. One end of the crossbar is inserted into the clamping hole, and the clamping block can rotate on the crossbar. After the clamping block rotates to the correct position, a locking device is installed on the clamping block to lock the opening of the clamping hole, thereby fixing the clamping block on the crossbar. The dust removal brush and the blower nozzle are fixedly installed on the corresponding clamping blocks.
[0017] As a preferred technical solution: The locking element can be a locking bolt, which is installed in the locking hole on the clamping block.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] Example 1 like Figures 1-5 As shown in the figure, this embodiment proposes a bottle cap dust removal device, including a connecting and fixing bracket 1. A dust removal brush 2 and a blowing nozzle 3 are installed on the connecting and fixing bracket 1. The dust removal brush 2 and the blowing nozzle 3 are arranged side by side on the connecting and fixing bracket 1. The dust removal brush 2 is arranged horizontally, and the blowing nozzle 3 is arranged obliquely towards the bottle cap 7 of the product. The bristles of the dust removal brush 2 can contact the side of the bottle cap 7, and there is a gap between the blowing nozzle 3 and the bottle cap 7.
[0029] In this embodiment, the bristles of the dust removal brush 2 are soft.
[0030] In this embodiment, the air nozzle 3 is tilted at 45° toward the bottle cap 7, but not limited to 45°. Tilting the air nozzle 3 prevents the product from turning or becoming unstable due to excessive direct airflow from the nozzle.
[0031] The dust removal brush 2 is not limited to a horizontal arrangement; it can also be arranged at an angle towards the bottle cap 7, ensuring that the bristles of the dust removal brush 2 can lightly sweep the side of the bottle cap 7. Figure 1 As shown, the bottle cap 7 has a marking on its side.
[0032] The blower nozzle 3 is connected to the air supply pipe 6, and the air supply pipe 6 is equipped with a control switch 5 and a pipe-type throttle valve 4. The control switch 5 is used to control the on / off of the air supply, and the pipe-type throttle valve 4 is used to control the wind speed and air volume, and to regulate the air pressure.
[0033] The connecting and fixing bracket 1 is arranged on one side of the conveying mechanism, and the dust removal brush 2 is closer to the starting end of the conveying mechanism than the blowing nozzle 3.
[0034] Multiple products are arranged sequentially on the conveyor mechanism, which moves all products in the conveying direction. As the products move laterally along the conveyor mechanism, the dust removal brush 2 lightly brushes across the side of the product bottle cap 7, sweeping away the dust on the bottle cap 7, loosening the dust adhering to the surface of the bottle cap 7, reducing adhesion, and then the dust on the bottle cap 7 is blown away by the blower nozzle 3. At the same time, the dust removal brush 2 processes the bottle cap 7 of the next product, until all products have been processed by the dust removal brush 2 and the blower nozzle 3.
[0035] The conveying mechanism can be a conveyor belt 8, on which the product is placed. The product can be bottled wine, etc. The conveyor belt 8 can be a reused conveyor belt from the existing production line, without the need for additional belts.
[0036] In this embodiment, the connecting and fixing bracket 1 includes a vertical rod 101 and a horizontal rod 102. The horizontal rod 102 is connected to the upper end of the vertical rod 101, and the two are perpendicular to each other. The vertical rod 101 is used to fix it to the ground or the work surface. The dust removal brush 2 and the blower nozzle 3 are connected to the horizontal rod 102.
[0037] The vertical rod 101 and the horizontal rod 102 are connected by a cross-clamp connecting block 103. The cross-clamp connecting block 103 has a horizontal locking hole 104 and a vertical locking hole 105. Both the horizontal locking hole 104 and the vertical locking hole 105 have an opening on one side. One end of the vertical rod 101 is inserted into the vertical locking hole 105, and the opening of the vertical locking hole 105 is locked by installing a locking bolt on the cross-clamp connecting block 103. One end of the horizontal rod 102 is inserted into the horizontal locking hole 104, and the opening of the horizontal locking hole 104 is locked by installing a locking bolt on the cross-clamp connecting block 103, thereby fixing the vertical rod 101 and the horizontal rod 102 to the cross-clamp connecting block 103.
[0038] In this embodiment, the dust removal brush 2 and the blower nozzle 3 are connected to the crossbar 102 via a connector. The connector can be a clamping block 9, and two clamping blocks 9 are mounted on the crossbar 102. Each clamping block 9 has a clamping hole 901 with an opening on one side. One end of the crossbar 102 is inserted into the clamping hole 901, allowing the clamping block 9 to rotate on the crossbar 102. After the clamping block 9 is rotated into position, a locking bolt is fitted onto it to lock the opening of the clamping hole 901, thereby fixing the clamping block 9 to the crossbar 102. The dust removal brush 2 and the blower nozzle 3 are fixedly mounted on the corresponding clamping blocks 9, for example, by bolts, screws, etc. The dimensions of the two clamping blocks 9 can be determined according to the installation requirements of the dust removal brush 2 and the blower nozzle 3.
[0039] The connector is not limited to the clamp 9; other connectors that can connect the dust removal brush 2 and the blower nozzle 3 to the crossbar 102 may also be used.
[0040] In this embodiment, the vertical rod 101 and the horizontal rod 102 can be made of aluminum rods with nickel plating on the aluminum surface. This material has high hardness, is not easy to rust or deform, is easy to install and remove, and has a long service life. However, the above materials are only examples and are not limited to these materials.
[0041] The dimensions of the vertical rod 101 are: 200mm in length and 12mm in diameter. The dimensions of the horizontal rod 102 are: 300mm in length and 12mm in diameter. The dimensions of the cross clamp connecting block 103 are: 47*16*16mm, and the diameter of the lock hole is: 12mm.
[0042] The dust removal brush 2 is an H-shaped aluminum alloy dust removal brush. The base of the H-shaped aluminum alloy dust removal brush is made of aluminum alloy and its dimensions are 35mm*15mm*1.5mm. The bristles of the H-shaped aluminum alloy dust removal brush are made of plastic fiber and its dimensions are 50mm in length and 10mm in thickness. The blower nozzle 3 is made of ABS plastic and measures 90mm*47mm*12.5mm. It has 16 air outlet holes at its front end, which increases the compressed air blowing pressure and area. The nozzle is fixed to the corresponding clamping block 9 using a double-hole fixing method, and the hole diameter of the nozzle is 1mm.
[0043] The pipeline throttle valve 4 is model SA-08, suitable for fluid media (air), with an operating temperature of 0-60℃, a pipe diameter of 8mm, and a guaranteed pressure resistance of 0-1Mpa. The pipeline throttle valve 4 can adjust the air pressure and control energy consumption.
[0044] The control switch 5 is a PHV manual valve switch, model PHV8B two-way, with a pressure range of <0-10kgf / cm*2 (0-1Mpa)>, negative pressure <-750mmHg (10Tor)>, guaranteed pressure resistance of 1.5Mpa, heat preservation range of -20-70℃, and pipe diameter of 8mm. It can manually shut off the air pressure to avoid frequent adjustment of the air pressure.
[0045] The air supply duct 6 is a transparent PU air hose with an outer diameter of 8mm, an inner diameter of 5mm, and an operating temperature of -40-90℃. It is used to connect the blower nozzle 3 and the air source to deliver compressed air.
[0046] The effect of using the bottle cap dust removal device of this utility model for dust removal is compared with that of using compressed air and dust brushes alone:
[0047] Based on on-site observation and analysis of different manufacturers, bottle cap materials, and dust adhesion after inkjet printing, this utility model of a bottle cap dust removal device was designed and planned. By combining a dust brush and air blowing, the dust adhering to the bottle cap is removed, ensuring that the markings on the bottle cap are not obscured by dust. The markings on the bottle cap are clearly visible in the images captured by the OCR inspection equipment. This effectively solves the problem of dust adhesion on bottle caps, significantly reducing the false kick rate of the OCR inspection equipment, ensuring the equipment's detection rate, the orderly operation of the production line, stabilizing production line efficiency, and ensuring production effectiveness. Product quality and production progress are effectively guaranteed, and the labor intensity of employees is reduced. At the same time, it improves the product's aesthetics and reduces the labor intensity of packaging workers.
[0048] The bottle cap dust removal device of this invention was repeatedly tested on site and achieved significant dust removal effect. The online operation effect met expectations, verifying the feasibility of the solution.
[0049] The bottle cap dust removal device of this invention is low in cost and easy to maintain, and can also be applied to other packaging production lines.
