Description

Technical Field

[0001] This application relates to the field of bottle cap feeding technology, and in particular to a bottle cap feeding device. Background Technology

[0002] In the liquor production industry, the production and assembly of bottle caps are crucial for ensuring product quality and packaging integrity. After initial production, bottle caps are sent to the production line for subsequent testing, capping, and other operations.

[0003] However, some bottle cap feeding processes still rely on traditional manual methods, where workers manually place the caps one by one on the conveyor line. While this method is simple and straightforward, it has significant drawbacks. Workers struggle to maintain a high-speed and stable operating rhythm for extended periods, resulting in uneven feeding intervals. This, in turn, affects the overall operating speed of the production line, hindering the efficient connection of subsequent processes such as inspection and capping, and ultimately reducing the overall efficiency of the production process.

[0004] Secondly, manual operation is easily affected by various factors, such as worker fatigue and concentration, which may lead to problems such as inaccurate bottle cap placement or inconsistent orientation, affecting the accuracy of subsequent testing and the smooth capping process, and may even cause product defects and increase production costs.

[0005] To address the aforementioned issues, a bottle cap feeding device is now designed. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a bottle cap feeding device that solves the problem in related technologies where the bottle cap feeding process still relies on traditional manual feeding methods, where workers manually place the bottle caps one by one on the conveyor line, which affects production efficiency.

[0022] Please see Figures 1-3 A bottle cap feeding device includes a material bin 1 and a conveyor 6. The material bin 1 has a vertically arranged lifting mechanism 2 on one side, a guide plate 3 on one side of the lifting mechanism 2, and a blowing unit 4 on the other side. A feeding chute 5 is connected to the bottom of the guide plate 3. The lifting mechanism 2 lifts the bottle caps inside the material bin 1 upwards, and the blowing unit 4 blows the bottle caps lifted by the lifting mechanism 2 onto the guide plate 3. The bottle caps on the guide plate 3 fall sequentially onto the feeding chute 5, and the other end of the feeding chute 5 extends above the conveyor 6 to feed the bottle caps onto the conveyor 6.

[0023] The bottle caps are placed in the material box 1, which provides storage space for the bottle caps.

[0024] The lifting mechanism 2 starts operating, and the bottle caps at the bottom of the material box 1 are lifted one by one. When the bottle caps are lifted to a certain height and close to the guide plate 3, the blowing unit 4 starts. The blowing unit 4 blows the bottle caps from the lifting mechanism 2 onto the guide plate 3. After the blown bottle caps fall onto the guide plate 3, they slide along the guide plate 3. The guide plate is connected to the feeding slide 5, and the bottle caps fall into the feeding slide 5 in sequence. The other end of the feeding slide 5 extends to the top of the conveyor 6. The bottle caps slide out from the feeding slide and fall onto the conveyor 6.

[0025] The bottle caps can be delivered to the conveyor 6 by the lifting mechanism 2, the guide plate 3, the blowing unit 4 and the feeding slide 5, realizing the automatic conveying process of bottle caps from the material box 1 to the conveyor 6. There is no need for manual placement of bottle caps one by one, which greatly shortens the feeding time and can continuously provide bottle caps to the conveyor at a faster speed, thereby improving the overall production efficiency.

[0026] Through the coordinated operation of the lifting mechanism 2, the guide plate 3, the blowing unit 4, and the feeding chute 5, the bottle caps can be lifted, blown, and transported stably, reducing production interruptions caused by unstable manual operation and ensuring the continuity of the production process.

[0027] like Figure 1 and Figure 2 As shown, the material box 1 in this embodiment has a chamber for storing bottle caps. The top and one side of the material box 1 are open, and the other side is conical for guiding the bottle caps.

[0028] The bottle caps are placed inside the material box 1 in the chamber for storing the bottle caps. One side of the material box 1 is conical. The conical structure can naturally guide the bottle caps toward the opening side of the material box 1 and the direction of the lifting mechanism 2 by utilizing its own shape characteristics, so that the bottle caps gradually gather, reducing the formation of dead corners in the material box, and making it easier for the lifting mechanism to pick up the bottle caps.

[0029] like Figure 2 , 3 and Figure 4 As shown, in one embodiment, the lifting mechanism 2 includes a belt conveyor 21 embedded in an opening on one side of the material box 1. The belt conveyor 21 has a conveyor belt 211, and a plurality of spacers 22 are sequentially arranged on the conveyor belt 211. The length of each spacer 22 is 3-5 cm. Two baffles 23 are arranged opposite each other on the belt conveyor 21, located at both ends of the spacers 22. The baffle 23 near the end of the guide plate 3 has a discharge port 24. The blowing unit 4 is arranged on the other baffle 23 and is opposite to the guide plate 3.

[0030] The belt conveyor 21 starts to operate, and the conveyor belt 211 on it circulates. Multiple partitions 22 with a length of 3-5cm are arranged sequentially on the conveyor belt 211.

[0031] When the conveyor belt 211 moves, the spacers 22 will enter the bottle caps piled up at the bottom of the hopper in sequence. Due to the presence of the spacers 22, as the conveyor belt 211 moves upward, the spacers 22 can carry a certain number of bottle caps up with them.

[0032] Two baffles 23 are located at both ends of the spacer 22. During the lifting process, the baffles 23 restrict the position of the bottle cap, prevent the bottle cap from sliding off the sides of the spacer 22, and ensure that the bottle cap rises steadily along the direction of the spacer 22.

[0033] When the spacer 22 carries the bottle cap up to the position of the baffle 23 near one end of the guide plate 3, the baffle 23 is provided with a discharge port 24, at which time the bottle cap reaches the discharge position.

[0034] The blowing unit 4 is set on the baffle 23 on the other side and is positioned opposite to the guide plate 3. The blowing unit 4 blows the bottle cap at the outlet 24 and makes it roll towards the guide plate 3 on the opposite side.

[0035] The multiple partitions 22 on the conveyor belt 211 can carry multiple bottle caps at a time for lifting, which improves the lifting efficiency of bottle caps and can lift a large number of bottle caps from the bottom of the material box to the discharge position in a short time, thus meeting the production line's requirements for feeding speed.

[0036] The 22-length divider is 3-5cm long, which ensures that a sufficient number of bottle caps are carried during the lifting process, improving the efficiency of a single lift, while preventing the bottle caps from falling off or getting disorganized during the lifting process due to excessive length, thus ensuring the stability of the lifting process.

[0037] like Figure 3 and Figure 7 As shown, in one embodiment, there is a gap of 3-5cm between the bottom of the belt conveyor 21 and the material box 1 for the spacer strip 22 to pass through; a U-shaped baffle 25 is provided between the outer sides of the two baffle strips 23, the U-shaped baffle 25 is located at the bottom of the belt conveyor 21 to prevent bottle caps from passing through, and there is a gap of not less than 3mm between the U-shaped baffle 25 and the baffle strips 23 to avoid friction.

[0038] There is a 3-5cm gap between the bottom of the belt conveyor 21 and the hopper 1 to allow the spacer bar 22 to pass through smoothly.

[0039] When the belt conveyor 21 starts to operate, the conveyor belt 211 drives the spacer 22 to make a cyclical movement. When the spacer 22 passes through the bottom opening of the material box 1, it will extend into the bottle caps piled up in the material box. Due to the existence of the gap, the spacer 22 can enter the bottom of the material box 1 without any obstruction and scoop up the bottle caps, which will be lifted up as the conveyor belt 211 rises.

[0040] A U-shaped baffle 25 is provided between the outer sides of the two baffles 23, and the U-shaped baffle 25 is located at the bottom of the belt conveyor 21. The U-shaped baffle 25 can block the bottle cap and prevent it from leaking out through the space between the bottom of the belt conveyor 21 and the surrounding structures such as the material box 1.

[0041] A gap of no less than 3mm is left between the U-shaped baffle 25 and the baffle strip 23 to prevent direct contact and friction between the baffle strip 23 and the U-shaped baffle 25, and to ensure that the various components of the equipment can operate relatively independently and stably.

[0042] like Figure 2 and Figure 3As shown, in one embodiment, the guide plate 3 includes a fixed plate 31 disposed on one side of the belt conveyor 21, and a rectangular frame 32 disposed on the fixed plate 31. The rectangular frame 32 has a feed inlet 33 at one end near the spacer 22. The bottom end of the rectangular frame 32 is inclined downward towards the side away from the belt conveyor 21, and the bottom end of the rectangular frame 32 is provided with a discharge outlet 34 on the side away from the belt conveyor 21.

[0043] When the spacer 22 carries the bottle cap to the discharge position, the blowing unit 4 works to blow the bottle cap out from the side near the spacer 22. Since the fixing plate 31 of the guide plate 3 is set on the side of the belt conveyor 21, and the rectangular frame 32 has a feed port 33 at the end near the spacer 22, the blown bottle cap will enter the interior of the rectangular frame 32 through the feed port 33.

[0044] The bottom of the rectangular frame 32 is tilted downwards towards the side away from the belt conveyor 21. The bottle caps that enter the rectangular frame 32 will slide downwards along the tilted bottom surface of the rectangular frame 32 under their own weight. By utilizing the principle of gravity, the bottle caps can automatically move in the discharge direction without the need for additional power, thus saving energy.

[0045] The bottle cap slides along the bottom of the rectangular frame 32 to the discharge port 34 on the side away from the belt conveyor 21, and enters the feeding chute 5.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment, the feeding slide 5 is L-shaped, and the corner of the feeding slide 5 is arc-shaped; the feeding slide 5 has a chamber 51 for sliding the bottle cap inside, and both ends are open; one end of the feeding slide 5 is connected to the discharge port 34 of the rectangular frame 32; the feeding slide 5 is provided with an observation hole 52 that communicates with the chamber 51.

[0047] After the rectangular frame 32 of the guide plate 3 discharges the bottle cap from the discharge port 2 34, since one end of the feeding slide 5 is connected to the discharge port 2 34, the bottle cap will enter the chamber 51 of the feeding slide 5 under its own gravity. At this time, the L-shaped structure of the feeding slide 5 provides a specific movement path for the bottle cap.

[0048] The feeding chute 5 is L-shaped with an arc at the corner. When the bottle cap slides to the corner, the arc design allows the bottle cap to smoothly change its direction of movement. Compared with a right-angle corner, the arc corner reduces the collision and friction between the bottle cap and the inner wall of the chute, reducing the risk of the bottle cap getting stuck or damaged at the corner, and ensuring that the bottle cap can smoothly continue to slide through the corner.

[0049] In the straight section of the feeding chute 5, the bottle cap slides along the chamber 51 to the other end under the action of gravity. After the bottle cap slides to the opening at the other end of the feeding chute 5, it will be discharged from the opening and fall onto the conveyor 6.

[0050] The observation hole 52 on the feeding slide 5 is connected to the chamber 51. The operator can observe the sliding of the bottle cap in the feeding slide 5 in real time through the observation hole 52. If any abnormality occurs, the operator can handle the bottle cap through the observation hole 52 to ensure the smooth progress of the feeding process.

[0051] like Figure 5 and Figure 6 As shown, in one embodiment, the conveyor 6 is provided with two guide plates 61 located on both sides of the feeding chute 5, and the guide plates 61 are used to guide the bottle caps; the conveyor 6 is a belt conveyor, and there is a gap of not less than 3mm between the feeding chute 5 and the conveyor belt of the conveyor 6.

[0052] After the bottle cap is discharged from the feeding chute 5, it will enter the second conveyor belt of the conveyor 6. The two guide plates 61 are set opposite to each other to form a channel. The bottle cap moves forward under the drive of the second conveyor belt. The guide plates 61 can limit the lateral movement range of the bottle cap, prevent the bottle cap from deviating from the predetermined conveying path during the conveying process, and ensure that the bottle cap is stably conveyed forward along the second conveyor belt.

[0053] Conveyor 6 is a belt conveyor. Its working principle involves a drive unit that rotates the second conveyor belt in a cyclical manner. Under the action of friction, the second conveyor belt transports the bottle caps placed on it from the beginning to the end of the conveyor. Belt conveyors are characterized by stable and continuous transport, ensuring that the bottle caps are not subjected to significant impact during transport, thereby reducing the risk of damage. This is existing technology and will not be elaborated further.

[0054] A gap of not less than 3mm is provided between the feeding slide 5 and the second conveyor belt of the conveyor 6. This gap can prevent direct friction between the feeding slide 5 and the second conveyor belt. If there is no gap between the two, the second conveyor belt will wear faster during the operation of the conveyor 6.

[0055] like Figure 1 and Figure 3 As shown, in one embodiment, the blowing unit 4 includes a plurality of air pipes 41 disposed on a side baffle 23. The baffle 23 has through holes for accommodating the air pipes 41. One end of the air pipe 41 is provided with an air nozzle 42 located in the through hole. The other end of the air pipe 41 is connected to a main pipe 43, which is connected to the air outlet of the blower 44. The air nozzle 42 is disposed opposite to the guide plate 3 and is located between the feed inlets 33.

[0056] After the fan 44 is started, it draws in air from the surrounding environment, pressurizes it, and discharges it from the outlet. The pressurized air is transported through the main pipe 43, which plays the role of gathering and distributing the gas, and evenly distributing the airflow generated by the fan 44 to each connected air pipe 41.

[0057] Each air pipe 41 is equipped with an air nozzle 42 at one end. The air nozzle 42 is located in the through hole opened on the baffle 23. When the airflow in the main pipe 43 enters the air pipe 41, it will be ejected at high speed through the air nozzle 42. Since the air nozzle 42 is set opposite to the guide plate 3 and is located between the feed inlet 33, the ejected airflow can directly act on the bottle cap on the partition 22, blowing the bottle cap off the partition 22, entering through the feed inlet 33 and falling onto the guide plate 3.

[0058] The high-speed airflow ejected through the nozzle 42 exerts a force on the bottle cap, making the bottle cap slide more smoothly on the spacer 22 and the guide plate 3, reducing the friction between the bottle cap and the spacer 22 and the guide plate 3, and preventing the bottle cap from getting stuck or piling up due to friction.

[0059] The airflow ejected from the nozzle 42 can form an air cushion between the bottle cap and the spacer 22 and the guide plate 3, effectively reducing the direct contact area between the two, thereby reducing friction and making the bottle cap slide more easily and quickly on the spacer 22 and the guide plate 3. This reduces the time the bottle cap stays on the guide plate 3 and improves the efficiency of the entire production process.
