[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 7 As shown, this utility model provides an automatic capping machine for spray filling production, including a main structure 1, which includes a conveyor belt 11, a first hydraulic cylinder 13 and a drive motor 14.

[0028] The screw cap structure 2 includes a fixing frame 21, a connecting rod 24, a connecting seat 25, a connecting rod 27, a hinge seat 29 and a hinge rod 210, and the connecting rod 24, the connecting seat 25, the connecting rod 27, the hinge seat 29 and the hinge rod 210 are all provided in three sets. The upper surface of the fixing frame 21 is fixedly connected to the output shaft of the drive motor 14.

[0029] The limiting structure 3 has two sets, and includes a mounting base 31, a fixing base 33, a connecting groove 34, a limiting rod 35, a pressure spring 36, a connecting plate 37, a fixing block 38, and a locking block 311. The two sets of mounting bases 31 are respectively fixedly connected to the outer surfaces of both sides of the conveyor belt 11.

[0030] A support frame 12 is fixedly connected to the outer surface of one side of the conveyor belt 11. A first hydraulic cylinder 13 is installed on the upper surface of the support frame 12. A drive motor 14 is fixedly connected to the lower end of the push rod inside the first hydraulic cylinder 13. Limiting posts 15 are fixedly connected to the outer surfaces of both sides of the drive motor 14, and the limiting posts 15 are inserted into the interior of the upper surface of the support frame 12.

[0031] By activating the first hydraulic cylinder 13, the drive motor 14, the two sets of limit posts 15, and the capping structure 2 can be moved longitudinally in sync. The two sets of limit posts 15 can effectively improve the stability of the capping structure 2 during movement. Activating the drive motor 14 can drive the capping structure 2 to rotate as a whole, so that the capping structure 2 can be used for capping operations.

[0032] The second hydraulic cylinder 22 is installed on the inner surface of the fixed frame 21, and the lower end of the push rod inside the second hydraulic cylinder 22 is fixedly connected to the connecting plate 23. All three sets of connecting rods 24 are fixedly connected to the lower surface of the connecting plate 23, and all three sets of connecting rods 24 are slidably inserted into the interior of the lower surface of the fixed frame 21.

[0033] By activating the second hydraulic cylinder 22, the connecting plate 23 and the three sets of connecting rods 24 can be moved longitudinally, and the three sets of connecting rods 24 can improve the stability of the connecting plate 23 during movement.

[0034] Among them, three sets of connecting seats 25 are fixedly connected to the lower ends of three sets of connecting rods 24, and a connecting frame 26 is fixedly connected to the lower surface of the fixing frame 21. The connecting frame 26 is provided with three sets, and the three sets of connecting rods 27 are respectively hinged to the interior of the lower ends of the three sets of connecting frames 26.

[0035] The three sets of connecting frames 26 are hinged to the connecting rods 27, so that the three sets of connecting rods 27 can rotate around the hinge point with the three sets of connecting frames 26.

[0036] Among them, the lower ends of the three sets of connecting rods 27 are all fixedly connected to the cap plates 28, the three sets of hinge seats 29 are respectively fixedly connected to the upper ends of the three sets of connecting rods 27, the lower ends of the three sets of hinge rods 210 are respectively hinged to the interior of the three sets of hinge seats 29, and the upper ends of the three sets of hinge rods 210 are respectively hinged to the interior of the three sets of connecting seats 25.

[0037] The movement of the three sets of connecting seats 25 can drive the movement of the three sets of hinge rods 210. When the three sets of hinge rods 210 move, they can drive the three sets of cap plates 28, connecting rods 27 and hinge seats 29 to rotate synchronously. At this time, the distance between the three sets of cap plates 28 can be adjusted, which can effectively improve the applicability of the three sets of cap plates 28. The clamping surface of the cap plate 28 is an arc-shaped structure adapted to common spray caps. The surface is provided with silicone anti-slip texture, with a thickness of 2-3mm and a high-strength plastic material, ensuring that the cap is not damaged during clamping while providing sufficient friction.

[0038] The upper surface of the mounting base 31 is equipped with a third hydraulic cylinder 32, and one side of the fixed base 33 is fixedly connected to one end of the push rod inside the third hydraulic cylinder 32. The connecting groove 34 is opened inside the other side of the fixed base 33.

[0039] By activating the two sets of third hydraulic cylinders 32, the two sets of fixed seats 33 can be pushed to move laterally, and the two sets of fixed seats 33 can be moved closer to or further away from each other.

[0040] The limiting rod 35 is fixedly connected to both ends inside the fixed base 33, the pressure spring 36 is sleeved on the lower end of the limiting rod 35, the connecting plate 37 is slidably sleeved on the outer surface of the limiting rod 35, the lower surface of the connecting plate 37 is attached to the upper end of the pressure spring 36, and the fixing block 38 is fixedly connected to both ends of one side surface of the connecting plate 37 and is disposed inside the connecting groove 34.

[0041] The connecting plate 37 can slide longitudinally on the outer surface of the limiting rod 35, and the limiting rod 35 can improve the stability of the connecting plate 37 when sliding. The elastic force of the pressure spring 36 applies a vertical upward force to the connecting plate 37 and the fixing block 38, which can prevent the connecting plate 37 and the fixing block 38 from moving downward without external force. The pressure spring 36 has a free length of 30mm, a wire diameter of 2mm, and an elastic coefficient of 5-8N / mm, ensuring that it can provide an upward thrust of 10-15N in the natural state. When pressed, a pressure of 20-25N can be applied to compress the spring and separate the fixing block from the locking block.

[0042] Among them, a pressure plate 39 is fixedly connected to the upper surface of the middle position of the connecting plate 37, and the pressure plate 39 is inserted into the interior of the upper surface of the fixing base 33. One end of the locking block 311 is inserted into the interior of the connecting groove 34. The upper end of the fixing block 38 is locked with the locking block 311. The other end of the locking block 311 is fixedly connected to a clamping plate 310, and one side of the clamping plate 310 is in contact with the other side of the fixing base 33.

[0043] By pressing the pressure plate 39, the connecting plate 37 and the fixing block 38 can move downward synchronously inside the fixing seat 33, and the pressure spring 36 can be retracted, and the fixing block 38 can be disengaged from the locking block 311. At this time, pulling the clamping plate 310 can disengage one end of the locking block 311 from the inside of the connecting groove 34, thereby completing the disassembly of the clamping plate 310.

[0044] The working principle and usage process of this utility model are as follows: First, select a clamping plate 310 of appropriate size. Then, press the pressure plate 39 to push the connecting plate 37 and the fixing block 38 downward and abut the pressure spring 36 to retract. Then, insert the locking block 311 into the interior of the connecting groove 34. Next, release the pressure plate 39. The two sets of pressure springs 36 can abut the connecting plate 37 and the fixing block 38 upward through their own elasticity. At this time, the fixing block 38 can fix the position of the locking block 311 and the clamping plate 310. Repeat the above operation to install another set of clamping plates 310.

[0045] During use, the bottle moves on the upper surface of the conveyor belt 11. After moving between the two sets of limiting structures 3, the two sets of third hydraulic cylinders 32 can push the two sets of connecting grooves 34 and clamping plates 310 to move. At this time, the two sets of clamping plates 310 can clamp the bottle. Then, the first hydraulic cylinder 13 pushes the drive motor 14 and the capping structure 2 to move downward as a whole, so that the three sets of capping plates 28 are in a position parallel to the cap. Then, the second hydraulic cylinder 22 pushes the connecting plate 23 to move, causing the three sets of capping plates 28 to rotate inward. At this time, the three sets of capping plates 28 can clamp the cap. Then, the drive motor 14 is started to drive the capping structure 2 to rotate as a whole, and the assembly of the cap is completed.
