[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1 - Figure 2The utility model provides an embodiment: a drip-proof filling mechanism for a filling machine, comprising a bracket 1, the top of the bracket 1 is fixedly connected to a filling machine body 2, a conveyor belt 3 is arranged at the top of the bracket 1 at the front end of the filling machine body 2, the container can be conveyed by the arrangement of the conveyor belt 3, and a filling port 4 is arranged at the front end of the filling machine body 2, and the liquid inside the filling machine body 2 can flow out through the arrangement of the filling port 4.
[0033] Reference Figure 2 - Figure 4 A drip prevention device 5 is provided below the filling port 4. The drip prevention device 5 includes a shell 51. The top of the shell 51 penetrates and is fixedly connected to the outer wall of the filling port 4. The interior of the shell 51 is set to be hollow. A filling tube 52 is slidably connected to the inner wall of the shell 51. The outer wall of the filling tube 52 is matched with the inner wall of the shell 51 in size. A slide groove 53 is provided on the inner wall of the shell 51. Slide blocks 54 are fixedly connected to the left and right sides of the filling tube 52. The outer wall of the slide block 54 is slidably connected to the inner wall of the slide groove 53. The top of the slide block 54 is elastically connected to the inner wall of the slide groove 53 through a spring 55. One end of the spring 55 is fixedly connected to the top of the slide block 54, and the other end of the spring 55 is fixedly connected to the inner wall of the slide groove 53.
[0034] Reference Figure 2 - Figure 4 The inner wall of the shell 51 is slidably connected with a trapezoidal block 56, and a control groove 510 is provided at the bottom of the trapezoidal block 56. The inner wall of the shell 51 at the bottom end of the trapezoidal block 56 is slidably connected with a pushing block 57. The side wall surface of the pushing block 57 is smooth. The smooth surface setting ensures that the pushing block 57 can move downward a certain distance under the action of gravity without being subjected to external force. A cut corner is set at the lower right corner of the pushing block 57. The setting of the cut corner ensures that when the pushing block 57 contacts the top of the container, it can be forced to move upward. The top of the pushing block 57 is fixedly connected with a triangular block 58. The shape of the triangular block 58 is consistent with the shape of the control groove 510. The consistent shape setting ensures that when the triangular block 58 moves vertically upward, it can drive the pushing block 57 to move horizontally through the control groove 510. The inclined surface of the trapezoidal block 56 is set at one end close to the filling tube 52.
[0035] Reference Figure 2 - Figure 4One end of the trapezoidal block 56 away from the slider 54 is elastically connected to the inner wall of the shell 51 through a spring 2 59, one end of the spring 2 59 is fixedly connected to the end of the trapezoidal block 56 away from the slider 54, and the other end of the spring 2 59 is fixedly connected to the inner wall of the shell 51. The elastic force of the spring 1 55 is smaller than the elastic force of the spring 2 59. By comparing the elastic forces of the spring 1 55 and the spring 2 59, it is ensured that the trapezoidal block 56 can drive the slider 54 to move upward under the drive of the spring 2 59 without being subject to external force. The elastic force of the spring 2 59 is smaller than the friction force between the container placed on the conveyor belt 3 and the conveyor belt 3. By setting the size of the friction force, it is ensured that when the top end of the container contacts the pushing block 57, the top end of the container can push the pushing block 57, and will not be unable to continue moving under the restriction of the pushing block 57.
[0036] Reference Figure 3 - Figure 5 A drip-proof component 6 is provided at the lower end of the shell 51. The drip-proof component 6 includes a mounting groove 61. The mounting groove 61 is opened on the inner wall of the shell 51. A rotating shaft 62 is fixedly connected to the inner wall of the mounting groove 61. A baffle 63 passes through the outer wall of the rotating shaft 62 and is rotatably connected. The thickness of the baffle 63 is almost the same as that of the mounting groove 61. By comparing the thickness of the baffle 63 with that of the mounting groove 61, it is ensured that the filling tube 52 will not be hindered by the baffle 63 when moving downward. A rubber pad is provided at one end of the baffle 63 away from the rotating shaft 62. By setting the rubber pad, it is ensured that the two baffles 63 can fit tightly when in contact to ensure that there is no liquid dripping. The lower end of the baffle 63 is elastically connected to the inner wall of the mounting groove 61 through a spring sheet 64. One end of the spring sheet 64 is fixedly connected to the lower end of the baffle 63, and the other end of the spring sheet 64 is fixedly connected to the inner wall of the mounting groove 61.
[0037] Working principle: When in use, the staff starts the equipment and places the container to be filled on the conveyor belt 3. When the container moves to contact with the right-end push block 57 under the drive of the conveyor belt 3, only the right-end push block 57 moves upward under the contact with the top of the container. Therefore, the right-end push block 57 makes the trapezoidal block 56 move to the right under the control of the control groove 510 through the triangular block 58. At this time, since the trapezoidal block 56 on the left side still limits the slider 54, the position of the filling tube 52 remains unchanged.
[0038] When the container continues to move until both the left and right ends push the pushing blocks 57, the bottom end of the slider 54 is not subject to the upward thrust, so the slider 54 moves downward again driven by the spring 1 55, and drives the filling tube 52 downward through the slider 54, so that the filling tube 52 moves to a position that just enters the container entrance, and the conveyor belt 3 is paused at this time to perform the filling operation, and when the filling operation is completed, the conveyor belt 3 is started again.
[0039] After the conveyor belt 3 is started, since the opening of the container is larger than the filling tube 52, even if the filling tube 52 is not reset, the container can still move a certain distance. After moving a certain distance, the top of the container is just out of contact with the pushing block 57. When the pushing block 57 is out of contact with the container, the trapezoidal block 56 is reset under the drive of the spring 2 59, thereby pushing the slider 54 through the inclined surface above the trapezoidal block 56, so that the slider 54 moves upward, and the slider 54 drives the filling tube 52 to move upward, so that the container can be smoothly moved to leave the filling area.
[0040] During the process of pushing block 57 moving upward, pushing block 57 drives triangular block 58 to move upward. At this time, triangular block 58 contacts the inner wall edge of control groove 510. When triangular block 58 continues to move upward, triangular block 58 contacts the inclined surface of control groove 510 through the inclined surface, so that the inclined surface of control groove 510 moves toward the same horizontal position as the inclined surface of triangular block 58, thereby achieving the effect of changing the horizontal position of trapezoidal block 56.
[0041] When the filling tube 52 moves downward, the filling tube 52 applies a force from top to bottom to the baffle 63, so that the baffle 63 rotates, thereby ensuring that the baffle 63 does not affect the up and down movement of the filling tube 52. When the filling tube 52 is reset, the baffle 63 is restored to a horizontal state driven by the spring 64, so that the liquid adhered to the inner wall of the filling tube 52 will not drip onto the conveyor belt 3 during non-filling operation.
[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
