Description

Technical Field

[0001] This utility model relates to the field of filling equipment, and in particular to a filling machine with adjustable filling volume. Background Technology

[0002] Filling machines are a small category of packaging machines. From the perspective of packaging materials, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. In terms of the degree of automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines.

[0003] In existing technologies, although filling machines can control the filling volume by controlling the movement distance of the piston inside the conveying cylinder, the limited volume of the conveying cylinder means that when filling materials exceeding the cylinder's capacity, the piston needs to be reset to re-extract materials before filling. This makes it difficult to stably fill large volumes. Furthermore, the piston needs to suck up materials before each filling, and the feeding interval affects filling efficiency. Therefore, a filling machine with adjustable filling volume is proposed to solve the above problems. Summary of the Invention

[0017] 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.

[0018] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a filling machine with adjustable filling volume, including a housing 1 for mounting other components. A conveyor belt 2 for conveying filling barrels is provided on the inner wall of the housing 1. An electric push rod 7 for driving a stable discharge assembly 5 is installed on the inner wall of the housing 1. A material box 4 for storing materials is fixedly connected to the inner wall of the housing 1. A stable filling mechanism is provided on the inner wall of the housing 1, including the stable discharge assembly 5. The stable discharge assembly 5 can continuously and stably fill materials. The stable discharge assembly 5 is located at the bottom of the material box 4, stably conveying the materials inside the material box 4. The stable discharge assembly 5 includes a three-way valve 51, which controls the discharge of materials from the two side conveying cylinders 54. The three-way valve 51 is prior art and is applicable in this field. The technical personnel in the field can implement this. Since it is existing technology, it will not be described in detail in this case. The three-way valve 51 is fixedly connected to the inner wall of the housing 1 and is supported and fixed by the housing 1. The bottom of the three-way valve 51 is fixedly connected to the mounting base 52 for mounting the nozzle 53. The bottom of the mounting base 52 is fixedly connected to the nozzle 53 for spraying out the material. Both sides of the three-way valve 51 are fixedly connected to the conveying cylinder 54 for placing the material. The inner wall of the conveying cylinder 54 is piston-connected to the piston head 55. The piston head 55 is used to squeeze out the material inside the conveying cylinder 54. The inner wall of the piston head 55 is fixedly connected to the connecting rod 56 for pushing and pulling the piston head 55 to move. The end of the connecting rod 56 away from the piston head 55 is fixedly connected to the push frame 57 for driving the connecting rod 56 to move.

[0019] Reference Figure 1 , Figure 2 and Figure 3The stabilizing filling mechanism also includes a positioning assembly 6 for positioning the filling cylinder below the nozzle 53. The positioning assembly 6 includes a motor 61 for driving a bidirectional lead screw 62 to rotate. The motor 61 is mounted on the inner wall of the housing 1 and supported and fixed by the housing 1. The output shaft of the motor 61 is fixedly connected to the bidirectional lead screw 62 for simultaneously moving other components to opposite sides. The outer wall of the bidirectional lead screw 62 is provided with a moving block 63 for cooperating with the bidirectional lead screw 62 to move the mounting frame 64. The upper surface of the moving block 63 is fixedly connected to the mounting frame 64 for supporting the limiting block 65. The end of the mounting frame 64 away from the moving block 63 is fixedly connected to a limiting block 65 for limiting the displacement and swaying of the filling cylinder. The 62 is rotatably connected to the inner wall of the housing 1 and is restricted and supported by the housing 1. The moving block 63 is slidably connected to the inner wall of the housing 1 and is restricted by the housing 1, so it will not rotate with the bidirectional screw 62. The mounting bracket 64 is slidably connected to the inner wall of the housing 1 and drives the movement of the limiting block 65. There are two sets of limiting blocks 65, which are symmetrically arranged with the center line of the conveyor belt 2 as the axis of symmetry. When the moving block 63 on the bidirectional screw 62 slides, it squeezes and restricts the filling barrel by moving towards the center. The two sets of limiting blocks 65 are staggered to avoid collision when restricting smaller filling barrels. The shape of the limiting block 65 is set as V-shaped, which allows the filling barrel to remain in a centered state.

[0020] Reference Figure 2 and Figure 4 The mounting base 52 is fixedly connected to the inner wall of the housing 1, and is supported and stabilized by the housing 1. The conveying cylinder 54 is fixedly connected to the inner wall of the housing 1 to ensure sufficient stability during operation. A support plate 3 is fixedly connected to the inner wall of the housing 1. The support plate 3 is set in an inclined position to push the filling barrel towards the center of the conveyor belt 2. The inclined setting makes the pushing process more stable. There are multiple sets of support plates 3, which are symmetrically arranged about the center line of the conveyor belt 2. There are multiple sets of conveying cylinders 54, which are arranged about the center line of the three-way valve 51. The center line is symmetrically arranged along the axis of symmetry. When the pusher 57 pushes the connecting rod 56 and piston head 55 on one side to move and squeeze the material inside the conveying cylinder 54, it will drive the connecting rod 56 and piston head 55 on the other side to stretch and extract the material inside the material box 4. The conveying cylinder 54 and the material box 4 are fixedly connected by the connecting pipe 8. A one-way valve is used at the connection between the connecting pipe 8 and the conveying cylinder 54 to prevent material from entering. The pusher 57 is slidably connected to the inner wall of the housing 1, driving the connecting rod 56 to move. The pusher 57 is fixedly connected to the output shaft of the electric push rod 7 and is pushed and pulled by the electric push rod 7.

[0021] Working principle: During use, the filling barrel is conveyed by the conveyor belt 2 to the area directly below the nozzle 53. Then, the motor 61 starts, driving the bidirectional lead screw 62 to rotate. This causes the two moving blocks 63 on both sides to slide synchronously towards the center along the inner wall of the housing 1. The moving blocks 63, through the mounting bracket 64, push two sets of V-shaped limiting blocks 65 to close, clamping the filling barrel from both sides. The V-shaped structure of the limiting blocks 65 forces the filling barrel to automatically center and position itself. The staggered arrangement of the blocks avoids interference, ensuring stable fixing of barrels of different sizes. The symmetrically arranged inclined support plates 3 assist in guiding the filling barrel to the center line of the conveyor belt 2, further enhancing positioning accuracy. The electric push rod 7 pushes the pusher frame 57 to one side, driving the connecting rod 56 and piston head 55 on that side to advance within the conveying cylinder 54. The material inside the cylinder is pressed into the filling barrel from the nozzle 53 via the mounting base 52. Simultaneously, the connecting rod 56 on the other side is... The pusher frame 57 moves in the opposite direction, and its piston head 55 retracts in the corresponding feed cylinder 54, drawing new material from the material box 4 through the connecting pipe 8. The one-way valve at the connection between the connecting pipe 8 and the feed cylinder 54 (not shown in the figure) prevents material backflow and ensures unidirectional flow. By controlling the stroke of the electric push rod 7, the pushing displacement of the piston head 55 is changed, directly adjusting the output volume of a single filling. When filling on one side is completed, the electric push rod 7 moves in the opposite direction, driving the pusher frame 57 to reset. At this time, the three-way valve 51 switches the passage direction, turning the original feeding side into the filling side and the original filling side into the feeding side, realizing continuous alternating operation. After filling is completed, the motor 61 reverses to drive the bidirectional lead screw 62, causing the limiting block 65 to release the clamp on the filling barrel. The conveyor belt 2 moves the filled barrel to the next station, and at the same time, the new barrel enters the positioning area, and the above process is repeated.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
