Description

Technical Field

[0001] This utility model relates to the field of fuel additive production, specifically an automatic capping machine for a fuel additive production line. Background Technology

[0002] Fuel additives are primarily used to clean engine carbon deposits, improve fuel efficiency, and reduce emissions. They typically consist of cleaning agents, lubricants, and antioxidants, and are added directly to the fuel tank to mix with the fuel before entering the combustion system. Their core function is to break down stubborn carbon deposits in the fuel injectors, intake valves, and combustion chamber, restoring engine power, reducing fuel consumption, and minimizing pollutant emissions caused by incomplete combustion. Some products also claim to optimize octane ratings to suit different gasoline grades. After filling, fuel additives require a capping machine to tighten the cap.

[0003] For example, according to authorization announcement number CN221319251U, an automatic capping machine includes a base plate, an electric telescopic rod at the top right end of the base plate, a clamping assembly, a placement plate, a transmission device at the top of the placement plate, a rotating rod at the left end of the placement plate, a rotating disk at the bottom of the rotating rod, a rotating cylinder at the bottom of the rotating disk, a spiral pattern on the rotating cylinder, a rotating moving device threadedly connected to the rotating cylinder, a sliding moving device on the rotating moving device, and a pushing structure inside the rotating cylinder. This automatic capping machine not only effectively tightens bottle caps but also allows for mechanical adjustment of the clamping force for different bottle cap sizes, thereby finding the appropriate clamping force for different sizes of bottle caps, extending the working cycle of the device, and improving the overall performance and efficiency.

[0004] However, the capping machine mentioned above requires manual placement of each bottle onto the base plate for capping, resulting in low capping efficiency and making it inconvenient for continuous production of fuel additives. Therefore, the market urgently needs to develop an automatic capping machine for fuel additive production lines to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic capping machine for a fuel additive production line, so as to solve the problem mentioned in the background art that the capping machine requires manual placement of the filling bottles one by one on the base plate for capping, which results in low capping efficiency and is not convenient for continuous production of fuel additives.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic capping machine for a fuel additive production line, comprising a base, an annular baffle fixedly connected to the upper edge of the base, a circular rotating seat rotatably connected to the upper end of the base and inside the lower end of the annular baffle, a rotating column fixedly connected to the middle of the upper end of the circular rotating seat, a circular support plate fixedly connected to the upper end of the rotating column extending from the upper end of the annular baffle, a circular positioning plate fixedly connected to the middle of the rotating column and inside the upper end of the annular baffle, a plurality of electrically controlled telescopic rods fixedly connected in an annular array on the upper surface of the circular support plate, a tightening motor fixedly connected to the lower end of the telescopic end of the electrically controlled telescopic rod extending from the lower end of the circular support plate, a fixing cylinder fixedly connected to the lower end of the output shaft of the tightening motor, and a capping device connected to the lower end of the fixing cylinder.

[0007] Preferably, the annular baffle is provided with a feed inlet and a discharge outlet in the middle of both sides, and an arc-shaped feed guide plate and an arc-shaped discharge guide plate are fixedly connected to the front end of the feed inlet and the discharge outlet and between the circular rotating seat and the circular positioning plate, respectively. A first infrared recognition device and a second infrared recognition device are fixedly connected to the rear ends of the upper end of the annular baffle, respectively.

[0008] Preferably, a limiting tube is fixedly connected to the middle of the upper surface inside the base, a drive motor is fixedly connected to one side inside the base, and a worm gear is fixedly connected to the output shaft of the drive motor.

[0009] Preferably, a rotating column is fixedly connected to the middle of the lower end face of the circular rotating seat. The lower end of the rotating column extends through the limiting tube into the interior of the base and is fixedly connected to a worm gear. The worm gear meshes with the teeth of the worm.

[0010] Preferably, the upper edge of the circular rotating seat is provided with a plurality of U-shaped grooves in an annular array, and the outer wall of the circular positioning plate is provided with a plurality of U-shaped slots in an annular array.

[0011] Preferably, the fixed cylinder has an internal telescopic groove, and keyways are provided on both sides of the telescopic groove. A connecting rod is fixedly connected to the upper middle part of the capping device, and connecting keys are fixedly connected to the upper ends of both sides of the connecting rod.

[0012] Preferably, the upper end of the connecting rod is inserted into the telescopic groove and the two connecting keys slide into the two keyways respectively, and a spring is provided inside the telescopic groove and at the upper end of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, by setting up a ring-shaped rotating multi-station structure, and with the feed port, discharge port and infrared recognition device, the automatic continuous feeding, capping and unloading of fuel bottle bodies are realized, which significantly improves production efficiency and solves the efficiency problem of traditional capping machines requiring manual operation one by one.

[0015] (2) In this utility model, the dual positioning design of U-shaped tray and U-shaped card slot and the external limit of the ring baffle are adopted. Combined with the precise control of the electric telescopic rod and the tightening motor, the stability and reliability of the capping process are ensured, the bottle body is effectively avoided from shifting or tipping, and the capping quality and consistency are improved.

[0016] (3) In this utility model, when the capping device descends along with the tightening motor, the capping device is first put on the bottle cap. As the tightening motor continues to drive the fixed cylinder to descend, the connecting rod can rise relative to the fixed cylinder and compress the spring, preventing the excessive force between the capping device and the bottle cap when the capping device descends, which would cause damage to the filling bottle.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5This utility model provides an embodiment of an automatic capping machine for a fuel additive production line, comprising a base 1, an annular baffle 102 fixedly connected to the upper edge of the base 1, a circular rotating seat 3 rotatably connected to the lower end of the base 1 inside the annular baffle 102, a rotating column 302 fixedly connected to the middle of the upper end of the circular rotating seat 3, a circular support plate 403 fixedly connected to the upper end of the rotating column 302 extending beyond the upper end of the annular baffle 102, and a circular positioning plate 401 fixedly connected to the middle of the rotating column 302 inside the upper end of the annular baffle 102, a plurality of U-shaped slots 301 arranged in an annular array on the upper edge of the circular rotating seat 3, and a plurality of U-shaped slots 401 arranged in an annular array on the outer wall of the circular positioning plate 401. 2. An inlet 103 and an outlet 104 are respectively provided in the middle of both sides of the annular baffle 102. An arc-shaped feed guide 105 and an arc-shaped outlet guide 106 are respectively fixedly connected to the front end of the inlet 103 and the outlet 104 and between the circular rotating seat 3 and the circular positioning plate 401. By setting belt conveyor lines on the outside of the inlet 103 and the outlet 104, the filling bottles are conveyed into the inlet 103 one by one by the belt conveyor lines. The arc-shaped feed guide 105 guides the filling bottles to the circular rotating seat 3 and inserts the lower end of the filling bottle into the U-shaped support groove 301. At the same time, the middle part of the filling bottle is inserted into the U-shaped slot 402 to achieve positioning of the filling bottle and make the filling bottle rotate backward with the circular rotating seat 3.

[0025] Please see Figure 2 and Figure 3 The first infrared recognition device 107 and the second infrared recognition device 108 are fixedly connected to the two rear ends of the upper end of the annular baffle 102, respectively. Multiple electrically controlled telescopic rods 404 are fixedly connected in an annular array to the upper surface of the circular support plate 403. A tightening motor 405 is fixedly connected to the lower end of the telescopic rod 404 after it extends beyond the lower surface of the circular support plate 403. A fixing cylinder 5 is fixedly connected to the lower end of the output shaft of the tightening motor 405. A capping device 6 is connected to the lower end of the fixing cylinder 5. When the circular rotating seat 3 rotates, it synchronously drives the circular positioning plate 401 and the circular support plate 403 to rotate synchronously. When the filling bottle rotates backward to the front end of the first infrared recognition device 107... The system identifies the bottle, causing the upper electrically controlled telescopic rod 404 of the identified bottle to drive the tightening motor 405 and the lower capping device 6 to descend, so that the capping device 6 is fitted onto the upper cap of the bottle. The tightening motor 405 drives the capping device 6 to rotate and tighten the cap. When the bottle cap is tightened, the bottle rotates with the circular rotating seat 3 to the second infrared identification device 108 for identification, which then causes the upper electrically controlled telescopic rod 404 to drive the tightening motor 405 and the lower capping device 6 to rise and detach from the cap. When the tightened bottle rotates with the circular rotating seat 3 to the discharge port 104, it is guided by the arc-shaped discharge guide plate 106 to the outer belt conveyor line of the discharge port 104 for output.

[0026] Please see Figure 2A limiting tube 101 is fixedly connected to the middle of the upper surface inside the base 1. A drive motor 2 is fixedly connected to one side inside the base 1. A worm gear 201 is fixedly connected to the output shaft of the drive motor 2. A rotating column 302 is fixedly connected to the middle of the lower surface of the circular rotating seat 3. The lower end of the rotating column 302 extends through the limiting tube 101 into the interior of the base 1 and is fixedly connected to a worm wheel 303. The worm wheel 303 meshes with the teeth of the worm gear 201. The drive motor 2 drives the rotating column 302 to rotate, thereby causing the rotating column 302 to drive the circular rotating seat 3 and its upper components to rotate synchronously.

[0027] Please see Figure 2 and Figure 5 The fixed cylinder 5 has a telescopic groove 501 inside, and keyways 502 are provided on both sides of the telescopic groove 501. A connecting rod 601 is fixedly connected to the middle of the upper end of the capper 6. Connecting keys 602 are fixedly connected to the upper ends of both sides of the connecting rod 601. The upper end of the connecting rod 601 is inserted into the telescopic groove 501 and the two connecting keys 602 slide into the two keyways 502 respectively. A spring 503 is provided inside the telescopic groove 501 and at the upper end of the connecting rod 601, so that the connecting rod 601 can rise and fall inside the telescopic groove 501. At the same time, the connecting keys 602 restrict the rotation between the connecting rod 601 and the fixed cylinder 5 by rising and falling along the keyways 502. When the capper 6 descends as a whole with the tightening motor 405, the capper 6 is first put on the bottle cap. As the tightening motor 405 continues to drive the fixed cylinder 5 to descend, the connecting rod 601 can rise relative to the fixed cylinder 5 and compress the spring 503, preventing the force between the capper 6 and the bottle cap from being too large when descending, which would damage the filling bottle.

[0028] Working Principle: During use, the filled but uncapped fuel additive bottles are continuously conveyed to the feed inlet 103 via a belt conveyor line outside the feed inlet 103. Guided by the arc-shaped feed guide plate 105, the lower end of the bottle is accurately embedded in the U-shaped groove 301 of the circular rotating seat 3, while the middle of the bottle is engaged in the U-shaped groove 402 of the circular positioning plate 401, achieving double positioning. The drive motor 2 drives the rotating column 302 to rotate through the worm gear 201-worm wheel 303 transmission mechanism, causing the circular rotating seat 3 and the positioned bottles on it to rotate synchronously. When the bottle rotates to the detection position of the first infrared recognition device 107, it triggers the corresponding station's electrically controlled telescopic rod 404 to press down, and the tightening motor 405 drives the fixed cylinder 5 and the capper 6 to descend. The capper 6 attaches the bottle cap, and then the tightening motor 405 drives the capper 6 to complete the capping operation. After being capped, the bottle continues to rotate to the second infrared recognition device 108. The electrically controlled telescopic rod 404 retracts, causing the capper 6 to detach from the cap. Finally, the bottle is guided to the discharge conveyor line at the discharge port 104 via the arc-shaped discharge guide plate 106, realizing a fully automatic continuous capping operation.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
