Description

Technical Field

[0001] This utility model belongs to the field of filling machine technology, specifically a filling head height adjustment structure for a filling machine. Background Technology

[0002] Filling machines play an important role in industrial production, especially in the food, daily chemical, and pharmaceutical industries. Their precise and efficient filling operations are a key link in ensuring product quality and production efficiency.

[0003] When adjusting the height of the filling head of a filling machine, a height adjustment structure is often used. Although the existing height adjustment structure can achieve basic lifting and lowering functions in actual use, most of the existing height adjustment structures rely on the self-locking mechanism formed by the friction between the threads to maintain the stability of the lifting plate. This self-locking method is easily affected by equipment vibration, causing the lifting plate to shift slightly up and down, thus affecting the filling accuracy of the filling head. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to address the above problems. This utility model provides a height adjustment structure for the filling head of a filling machine, which has the advantage of quickly limiting the lifting plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filling head height adjustment structure for a filling machine, comprising a base, a round rod fixedly connected to the top of the base, a lifting plate movably sleeved on the outer surface of the round rod, a mounting frame fixedly connected to the top of the lifting plate, a threaded rod threadedly connected to the inside of the mounting frame, a lifting block movably sleeved on the bottom of the threaded rod, connecting rods hinged to the left and right sides of the bottom of the lifting block, a connecting block hinged to the other end of the connecting rod, the outer surface of the connecting block movably connected to the inner surface of the lifting plate, a clamping block fixedly connected to the front of the connecting block, and the inner side of the clamping block movably connected to the outer surface of the lifting plate.

[0009] As a preferred embodiment of this utility model, a vertical rod is movably sleeved on the inner surface of the lifting plate, and the bottom of the vertical rod is fixedly connected to the top of the base.

[0010] As a preferred embodiment of this utility model, a drive motor is fixedly connected to the right side of the base, and a second lead screw is fixedly sleeved at the other end of the output shaft of the drive motor. The left side of the second lead screw passes through the base and extends into the interior of the base, and a T-shaped plate is threadedly sleeved thereon.

[0022] 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.

[0023] like Figures 1 to 6 As shown, this utility model provides a filling head height adjustment structure for a filling machine, including a base 1, a round rod 2 fixedly connected to the top of the base 1, a lifting plate 3 movably sleeved on the outer surface of the round rod 2, a mounting frame 4 fixedly connected to the top of the lifting plate 3, a threaded rod 5 threadedly connected inside the mounting frame 4, a lifting block 6 movably sleeved at the bottom of the threaded rod 5, connecting rods 7 hinged to the left and right sides of the bottom of the lifting block 6, a connecting block 8 hinged to the other end of the connecting rod 7, the outer surface of the connecting block 8 movably connected to the inner surface of the lifting plate 3, and a clamping block 9 fixedly connected to the front of the connecting block 8, the inner side of the clamping block 9 movably connected to the outer surface of the lifting plate 3.

[0024] The upward movement of the rotating threaded rod 5 will drive the lifting block 6 to move upward, which in turn causes the two connecting rods 7 to rotate and drive the two connecting blocks 8 to move towards each other. This causes the four clamping blocks 9 to move towards each other and clamp and fix with the round rod 2, thus achieving the purpose of quickly limiting the lifting plate 3 and ensuring the stability after the filling head height is adjusted.

[0025] Among them, the lifting plate 3 is internally fixedly connected to a limit rod 10, and the outer surface of the limit rod 10 is movably sleeved with the inner surface of the connecting block 8.

[0026] The design of the limit rod 10 serves to limit and support the connecting block 8, ensuring the stability of the horizontal movement of the connecting block 8.

[0027] The inner surface of the lifting plate 3 is threaded with a first lead screw 11. The bottom of the first lead screw 11 is movably connected to the inner surface of the top of the base 1. The top of the first lead screw 11 is fixedly connected with a turntable 12.

[0028] Rotating the turntable 12 will cause the first lead screw 11 to rotate, which will drive the lifting plate 3 to move up and down as a whole, thus achieving the purpose of height adjustment.

[0029] Among them, a pneumatic cylinder 13 is fixedly connected to the middle of the top of the lifting plate 3, and the bottom of the pneumatic cylinder 13 passes through the lifting plate 3 and extends to the bottom of the lifting plate 3 and is fixedly connected to the filling head 14.

[0030] When the pneumatic cylinder 13 is running, it will drive the filling head 14 to move downwards and insert into the collection bottle, thus preventing liquid from spilling during the filling process.

[0031] The inner surface of the lifting plate 3 is movably fitted with a vertical rod 15, and the bottom of the vertical rod 15 is fixedly connected to the top of the base 1.

[0032] The vertical rod 15 is designed to limit the movement of the lifting plate 3, ensuring the stability of the lifting plate 3's up and down movement.

[0033] A drive motor 16 is fixedly connected to the right side of the base 1. A second lead screw 17 is fixedly sleeved at the other end of the output shaft of the drive motor 16. The left side of the second lead screw 17 passes through the base 1 and extends into the interior of the base 1, and a T-shaped plate 18 is threadedly sleeved thereon. A rotating rod 19 is hinged to the left side of the T-shaped plate 18. A rectangular block 20 is hinged to the other end of the rotating rod 19. The outer surface of the rectangular block 20 is movably connected to the inner surface of the top of the base 1. A positioning plate 21 is fixedly connected to the top of the rectangular block 20. There are two positioning plates 21, and the bottom of both positioning plates 21 is movably connected to the top of the base 1.

[0034] When the drive motor 16 is running, the second lead screw 17 will rotate, causing the T-shaped plate 18 to move to the right. This will cause the two rotating rods 19 to rotate, causing the two rectangular blocks 20 to move towards each other. As a result, the two positioning plates 21 will move towards each other to center the collection bottle, thus improving the convenience of the device.

[0035] The base 1 has a crossbar 22 fixedly installed inside, and the outer surface of the crossbar 22 is movably connected to the inner surface of the T-shaped plate 18.

[0036] The design of the crossbar 22 serves to limit the movement of the T-shaped plate 18, enabling the T-shaped plate 18 to move horizontally in a stable manner.

[0037] Working principle and usage process of this utility model:

[0038] When adjusting the height of the filling head 14, first rotate the two threaded rods 5 downwards, which will drive the two lifting blocks 6 downwards. This will cause the four connecting rods 7 to rotate, causing the four connecting blocks 8 to move in opposite directions. This will cause the eight clamping blocks 9 to move in opposite directions and separate from the two round rods 2, thus releasing the limiting effect on the lifting plate 3. Then, by rotating the turntable 12, the first lead screw 11 will rotate, causing the lifting plate 3 to move up and down as a whole, achieving the purpose of adjusting the height of the filling head 14. After the height of the filling head 14 is adjusted, rotate the two threaded rods 5 upwards again, which will drive the eight clamping blocks 9 to reset and clamp and fix with the two round rods 2, achieving the purpose of quickly limiting the lifting plate 3 and ensuring the stability of the filling head 14 after height adjustment.

[0039] When filling the collection bottle, first place the collection bottle on top of the base 1, then start the drive motor 16, which will cause the second lead screw 17 to rotate and drive the T-shaped plate 18 to move to the right, which in turn causes the two rotating rods 19 to rotate and drive the two rectangular blocks 20 to move towards each other, thereby causing the two positioning plates 21 to move towards each other and center the bottle, improving the convenience of the device. Then start the pneumatic cylinder 13, which will drive the filling head 14 to move downward and insert into the inside of the collection bottle to complete the filling.
