Description

Technical Field

[0001] This utility model relates to the field of filling machine cleaning technology, specifically to a filling machine hopper tilting mechanism that is easy to clean. Background Technology

[0002] Filling machines are divided into liquid filling machines, paste filling machines, powder filling machines, etc. The filling machine hopper is an important component of the filling machine, mainly used to store and supply materials to be filled.

[0003] Patent CN218258989U discloses a quick-disassembly hopper for a constant pressure filling machine, including a hopper body. A fixed base is movably connected to the outer wall of the hopper body, and a snap-fit ​​groove is formed inside the top of the fixed base, which is movably connected to the hopper body. This quick-disassembly hopper for a constant pressure filling machine works by applying a pulling force to a limiting ball. The limiting ball drives a connecting rod and a clamping block to move towards the limiting ball, compressing a spring. The spring undergoes elastic deformation. Then, the hopper body is placed on the inner wall of the snap-fit ​​groove. Releasing the pulling force applied by the limiting ball causes the clamping block and connecting rod to move towards the hopper tube under the reaction force of the elastic deformation of the spring, clamping the hopper tube. A fixing ring is located below the clamping block. When the hopper body is directly removed, the clamping block acts as an obstruction. This device not only allows for quick disassembly and assembly of the hopper body but is also simple, quick, and easy to use.

[0004] In the existing technology, the hopper can be quickly disassembled and assembled by components such as limit balls and clamping blocks. However, the hopper does not need to be disassembled frequently during use. At most, the hopper is cleaned at the end of each day's work. However, if the hopper needs to be disassembled for cleaning, it will increase the cleaning steps. Moreover, the hopper is heavy and difficult to remove, which reduces the cleaning efficiency.

[0014] The beneficial effects of this utility model are: (1) When the hopper needs to be cleaned, the present invention uses the drive screw in the flipping unit and the cooperation of telescopic rod one and telescopic rod two to lift the hopper. At the same time as lifting, the gas spring and triangular block in the auxiliary unit can reduce the gravity of the hopper when it is lifted, thus facilitating the cleaning of the hopper. Moreover, with the setting of the flipping unit and the auxiliary unit, it is not necessary to remove the hopper during cleaning, but to simply flip the hopper 90 degrees, thereby improving the cleaning efficiency.

Detailed Implementation

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to the attached diagram. Figures 1-6As shown in the figure, a hopper tilting mechanism for a filling machine that is easy to clean is provided in an embodiment of the present invention, comprising a working unit, a tilting unit and an auxiliary unit; The working unit includes a workbench 1, a hopper 2, a tilting base 4, a fixing block 26, a hinge rod 25, and a connecting pipe 5; The flipping unit includes a drive box 6, a drive screw 7, a moving block 8, a telescopic rod 1 9, and a telescopic rod 2 10; The auxiliary unit includes an auxiliary box 15, a gas spring 16, a triangular block 20, a connecting rod 1 21, a connecting rod 22, and a connecting column 19; The hopper 2 is tilted via telescopic rod 9 and telescopic rod 10, and an auxiliary unit is used to reduce the resistance during tilting. During operation, when cleaning the hopper 2 is required, the drive screw 7 in the tilting unit, together with the telescopic rod 9 and the telescopic rod 10, lifts the hopper 2. At the same time as lifting, the gas spring 16 and the triangular block 20 in the auxiliary unit reduce the gravity of the hopper 2 during lifting, thus facilitating cleaning. Furthermore, due to the tilting unit and the auxiliary unit, the hopper 2 does not need to be removed during cleaning; it can be simply tilted 90 degrees, thereby improving cleaning efficiency.

[0021] like Figure 3 and Figure 4 As shown, a slot 14 is provided on the workbench 1; a drive box 6 is located below the slot 14 and is fixedly connected to the workbench 1; a drive screw 7 rotates inside the drive box 6; a moving block 8 is threadedly connected to the drive screw 7; a second telescopic rod 10 is slidably connected inside a first telescopic rod 9; the first telescopic rod 9 is hinged to the moving block 8; a tilting base 4 is fixedly connected to the hopper 2; a connecting groove 12 is provided on the tilting base 4; a connecting shaft 11 is rotatably connected inside the connecting groove 12; the end of the second telescopic rod 10 away from the first telescopic rod 9 rotates with the connecting shaft 11. When it needs to be lifted during operation, the drive screw 7 inside the drive box 6 rotates. When it rotates, it will drive the moving block 8 to move towards the hopper 2. When it moves, it will drive the telescopic rod 9 to move, and then drive the telescopic rod 10 to lift up, thereby lifting one end of the hopper 2. As the moving block 8 continues to move, the hopper 2 will be completely rotated to 90 degrees, which is convenient for the staff to clean. The telescopic rod 9 and the telescopic rod 10 are slidable, which can prevent tension from occurring when they move.

[0022] like Figure 6 As shown, there are two sets of fixed blocks 26, which are fixedly connected to the workbench 1; the hinge rod 25 is rotatably disposed in the flip base 4, and both ends of the hinge rod 25 are rotatably connected to the fixed blocks 26; the fixed blocks 26 and the hinge rod 25 are disposed at the end away from the connecting groove 12. During operation, the flipping base 4 is rotatably connected to the two side fixing blocks 26 via the hinge rod 25. When the hopper 2 flips, the hinge rod 25 is the center, and the other side is lifted by the telescopic rod 9 and the telescopic rod 10, so that the hopper 2 flips to 90 degrees, making it convenient for workers to clean.

[0023] like Figure 6 As shown, the auxiliary box 15 is located inside the workbench 1; the connecting column 19 is rotatably connected inside the auxiliary box 15; the gas spring 16 is fixedly connected to connecting seat 17 and connecting seat 2 18 at both ends respectively; connecting seat 17 is rotatably connected to the auxiliary box 15; a triangular block 20 is rotatably connected to the connecting column 19; one end of the triangular block 20 is rotatably connected to connecting seat 2 18; the end of the triangular block 20 away from connecting seat 2 18 is rotatably connected to connecting rod 1 21; the end of connecting rod 1 21 away from triangular block 20 is rotatably connected to connecting rod 2 22; the end of connecting rod 2 22 away from connecting rod 1 21 is rotatably connected to connecting seat 3 23; the end of connecting seat 3 23 away from connecting rod 2 22 is fixedly connected to the flip base 4. During operation, when the hopper 2 is lifted, the other end of the tilting base 4 will compress the connecting rod 22 through the connecting seat 3 23. The connecting rod 22 is set higher than the worktable 1. During the tilting, the connecting rod 22 will descend. During the descent, the connecting rod 1 21 will press down the triangular block 20. The central column of the triangular block 20 is connected to the connecting column 19. When one end of the triangular block 20 is pressed down, the other end will be lifted through the lever principle. During the lifting process, the gas spring 16 will be stretched. When the gas spring 16 is stretched, it will generate thrust. Thus, multiple sets of connecting rods help the hopper 2 to tilt, reducing the force required for the hopper 2 to tilt.

[0024] like Figure 3 As shown, a discharge hole 3 is provided in the middle of the hopper 2; the connecting pipe 5 is located below the discharge hole 3. During operation, the material in the hopper 2 is discharged through the discharge hole 3 and the connecting pipe 5. The connecting pipe 5 and the discharge hole 3 are not connected. When the hopper 2 is tilted, the connecting pipe 5 and the discharge hole 3 are separated.

[0025] like Figure 2 and Figure 3 As shown, a rocker arm 13 is rotatably connected to the side wall of the drive box 6; the output end of the rocker arm 13 is fixedly connected to the input end of the drive screw 7. During operation, the rocker arm 13 drives the drive screw 7 in the drive box 6 to rotate. The setting of components such as the gas spring 16 can reduce the force when rotating the rocker arm 13, thus helping the hopper 2 to tilt.

[0026] like Figure 2 As shown, the bottom of the workbench 1 is fixedly connected with anti-slip feet 24; multiple sets of anti-slip feet 24 are provided. During operation, the anti-slip feet 24 are made of rubber, which can prevent the worktable 1 from shaking when the hopper 2 is tilted.

[0027] like Figure 1 and Figure 2 As shown, a notch 27 is provided in the middle of the workbench 1; the drive box 6, the auxiliary box and the connecting pipe 5 are all located at the notch 27.

[0028] The working principle of this utility model is as follows: When it needs to be lifted, the drive screw 7 in the drive box 6 is rotated. When it rotates, it will drive the moving block 8 to move towards the hopper 2. When it moves, it will drive the telescopic rod 9 to move, and then drive the telescopic rod 10 to lift up, thereby lifting one end of the hopper 2. As the moving block 8 continues to move, the hopper 2 will be completely rotated to 90 degrees, which is convenient for workers to clean. The telescopic rod 9 and the telescopic rod 10 are slidably set, which can avoid tension when they move.

[0029] When the hopper 2 is lifted, the other end of the tilting base 4 will compress the connecting rod 22 through the connecting seat 3 23. The connecting rod 22 is set higher than the worktable 1. During the tilting, the connecting rod 22 will fall. During the falling, the connecting rod 1 21 will press down the triangular block 20. The central column of the triangular block 20 is connected to the connecting column 19. When one end of the triangular block 20 is pressed down, the other end will be lifted by lever principle. During the lifting, the gas spring 16 will be stretched. When the gas spring 16 is stretched, it will generate thrust. Thus, multiple sets of connecting rods help the hopper 2 to tilt, reducing the force required for the hopper 2 to tilt.

[0030] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
