Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically a bottle cap sorting machine. Background Technology

[0002] In liquid products, a common packaging method involves using bottles with caps for sealing, facilitating transportation, sales, and storage. To adapt to large-scale production, the cap-bottle assembly process in the sealing step is often automated. This type of solution requires the bottles and caps to be arranged in a regular pattern and positioned correctly to enable automatic feeding and sealing by the machine. Bottles, being relatively large in volume and mass, are easier to position and arrange sequentially.

[0003] The invention patent with publication number CN206188050U discloses a bottle cap sorting machine. It separates a pile of bottle caps one by one through a conveyor device. The machine uses a passage on the conveyor plate, a distance sensor, and a telescopic rod to collect bottle caps with inconsistent orientations back into a storage box, ensuring that the bottle caps output from the conveyor plate have the same orientation. This solves the problem that there are many bottle cap sorting machines, some semi-automatic and some fully automatic. Semi-automatic machines require manual handling to turn the bottle caps upside down and place them on the conveyor belt, while fully automatic machines cannot completely unify the orientation of the bottle caps, which is not conducive to screwing the bottle caps onto the bottle.

[0004] In existing bottle cap sorting machines, bottle caps that fail screening fall down from the lifting ramp, which knocks down bottle caps on the lower lifting ramp, affecting the feeding efficiency. At the same time, bottle caps that pass screening still risk falling when discharged, increasing the failure rate of the machine. To solve the above problems, this application proposes a bottle cap sorting machine. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes a bottle cap sorting machine. The guide rack directs the falling bottle caps to one end of the storage bin, preventing the falling bottle caps from landing on the feeding conveyor belt, thereby avoiding knocking the bottle caps off the lifting ramp and improving the sorting efficiency. After the bottle caps exceed the screening protrusion, the anti-fall plate limits the bottle caps, preventing them from falling off the lifting ramp during lifting or discharge, thus reducing the failure rate of the sorting machine and solving the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To solve the above technical problems, this utility model provides a bottle cap sorting machine, including a feeding conveyor belt and a storage box. The storage box is located below the feeding conveyor belt, and the bottom of the feeding conveyor belt is inserted into the inner cavity of the storage box. The surface of the feeding conveyor belt is provided with lifting inclined plates. The upper surface of the lifting inclined plates has an inclined structure, and the lifting inclined plates are equidistantly distributed on the surface of the feeding conveyor belt.

[0009] The feeding conveyor belt is provided with a screening protrusion in the middle;

[0010] The side wall of the feeding conveyor belt is welded with a mounting frame, and a material discharge frame is welded on the mounting frame. The material discharge frame is located below the screening protrusion.

[0011] The side wall of the feeding conveyor belt is provided with a discharge port, and a fall protection plate is provided on one side of the discharge port. The fall protection plate and the discharge port are located above the screening protrusion.

[0012] Preferably, a discharge guide plate is connected to the surface of the discharge port, and the discharge guide plate is inclined downward.

[0013] Preferably, the end of the discharge rack is located above the end of the inner cavity of the storage box, and the raw materials discharged by the discharge rack fall into the end of the inner cavity of the storage box.

[0014] Preferably, the bottom of the inner cavity of the storage box is provided with a pouring ramp, and the upper surface of the pouring ramp is inclined to the bottom of the upward conveyor belt.

[0015] Preferably, an installation groove is provided on the side wall of the feeding conveyor belt corresponding to the position of the discharge outlet, and a fan is installed in the inner cavity of the installation groove.

[0017] Preferably, a drive motor is installed on the top of the side wall of the feeding conveyor belt, and the drive motor is used to drive the feeding conveyor belt.

[0018] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0019] 1. In this utility model, the guide rack directs the falling bottle caps to one end of the storage bin, preventing them from landing on the feeding conveyor belt and thus avoiding knocking them off the lifting ramp. This improves the efficiency of bottle cap sorting. After the bottle caps exceed the screening protrusion, the anti-fall plate limits their movement, preventing them from falling off the lifting ramp during lifting or discharge, thus improving the smoothness of bottle cap discharge and reducing the failure rate of the sorting machine.

[0020] 2. This utility model, by combining a blower and an air guide hood, can apply a downward thrust to the bottle cap, making the bottle cap slide out more smoothly and avoiding jamming during discharge. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] like Figure 1-4 As shown, the present invention proposes a bottle cap sorting machine, which includes a feeding conveyor belt 1 and a storage box 2. The storage box 2 is located below the feeding conveyor belt 1. The bottom of the feeding conveyor belt 1 is inserted into the inner cavity of the storage box 2. The surface of the feeding conveyor belt 1 is provided with lifting inclined plates 4. The upper surface of the lifting inclined plates 4 has an inclined structure, and the lifting inclined plates 4 are equidistantly distributed on the surface of the feeding conveyor belt 1.

[0029] The feeding conveyor belt 1 is provided with a screening protrusion 3 in the middle;

[0030] The side wall of the feeding conveyor belt 1 is welded with an installation frame 5, and a discharge frame 6 is welded on the installation frame 5. The discharge frame 6 is located below the screening protrusion 3, and the end of the discharge frame 6 is located above the end of the inner cavity of the storage box 2. The raw material discharged by the discharge frame 6 falls into the end of the inner cavity of the storage box 2. The bottom of the inner cavity of the storage box 2 is provided with a discharge inclined plate 10, and the upper surface of the discharge inclined plate 10 is inclined to the bottom of the feeding conveyor belt 1.

[0031] The feeding conveyor belt 1 has a discharge port 7 on its side wall, and a fall arrestor plate 9 is provided on one side of the discharge port 7. The fall arrestor plate 9 and the discharge port 7 are located above the screening protrusion 3.

[0032] It should be noted that during the rotation of the feeding conveyor belt 1, the bottle caps are lifted along with the lifting inclined plate 4. When the bottle caps move to the screening protrusion 3, the weight of the cap opening and the cap bottom is different. When the cap opening faces the feeding conveyor belt 1, the center of gravity of the bottle cap shifts outward and it falls off the lifting inclined plate 4. The bottle caps that do not fall continue to rise. When they reach the discharge outlet 7, the bottle caps slide out of the discharge outlet 7 and are guided out by the discharge guide plate 8. The unloading rack 6 guides the fallen bottle caps to one end of the storage box 2, so that the falling bottle caps... The caps cannot fall onto the feeding conveyor belt 1, thus preventing them from falling off the lifting ramp 4. The bottom of the inner cavity of the storage box 2 guides the caps through the pouring ramp 10, allowing the caps to move quickly to below the feeding conveyor belt 1. This enables the feeding conveyor belt 1 to quickly lift the caps, improving the sorting efficiency. After the caps exceed the screening protrusion 3, the anti-fall plate 9 limits their movement, preventing them from falling off the lifting ramp 4 during lifting or discharge, thus reducing the failure rate of the sorting machine.

[0033] In this embodiment, as Figure 1 As shown, a discharge guide plate 8 is connected to the surface of the discharge port 7, and the discharge guide plate 8 is inclined downward.

[0034] It should be noted that the bottle caps are guided by the discharge guide plate 8, which allows the bottle caps to move quickly to the next process.

[0035] In this embodiment, as Figure 4 As shown, an installation groove 11 is provided on the side wall of the feeding conveyor belt 1 corresponding to the position of the discharge port 7. A fan 12 is installed in the inner cavity of the installation groove 11. An air guide hood 13 is installed on the surface of the fan 12. The exhaust port of the air guide hood 13 is flush with the inner wall of the feeding conveyor belt 1.

[0036] It should be noted that by combining the blower 12 with the air guide hood 13, a downward thrust can be applied to the bottle cap, making the bottle cap slide out more smoothly and avoiding jamming during material discharge.

[0037] In this embodiment, as Figure 1 As shown, a drive motor 14 is installed on the top of the side wall of the feeding conveyor belt 1, and the drive motor 14 is used to drive the feeding conveyor belt 1.

[0038] It should be noted that the drive motor 14 is used to drive the feeding conveyor belt 1.

[0039] The working principle and usage process of this utility model are as follows: The drive motor 14 drives the feeding conveyor belt 1, the bottom of which is inserted into the inner cavity of the storage box 2. During the rotation of the feeding conveyor belt 1, the bottle caps are lifted along with the lifting inclined plate 4. When the bottle caps move to the screening protrusion 3, the weight of the cap opening and the cap bottom is different. When the cap opening faces the feeding conveyor belt 1, the center of gravity of the bottle caps shifts outward and they fall off the lifting inclined plate 4. The bottle caps that do not fall continue to rise. When they reach the discharge outlet 7, the bottle caps slide out of the discharge outlet 7 and are guided out by the discharge guide plate 8. The unloading rack 6 guides the fallen bottle caps to one end of the storage box 2, preventing the falling bottle caps from falling back down. On the feeding conveyor belt 1, the bottle caps on the lifting ramp 4 are prevented from falling off. The bottom of the inner cavity of the storage box 2 is guided by the pouring ramp 10, so that the bottle caps move quickly to the bottom of the feeding conveyor belt 1. This allows the feeding conveyor belt 1 to quickly lift the bottle caps, which can improve the sorting efficiency of the bottle caps. After the bottle caps exceed the screening protrusion 3, the anti-fall plate 9 limits the bottle caps, which can prevent the bottle caps from falling off the lifting ramp 4 when lifting or discharging, and can reduce the failure rate of the sorting machine. The blower 12 and the air guide hood 13 are used to apply a downward sliding force to the bottle caps, making the bottle caps slide out more smoothly and avoiding the phenomenon of jamming during discharge.

[0040] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims or their equivalents.
