[0030] Example:
[0031] like Figures 1 to 4 As shown, an anti-dumping structure of liquid filling equipment includes a conveyor belt 12. The conveyor belt 12 is transported along its own length direction. Motors and pulleys for driving the conveyor belt 12 to move are arranged at both ends of the length direction of the conveyor belt 12. At the same time, in order to ensure the bearing capacity during movement, it should be known that a support plate is arranged on the lower side of the top of the conveyor belt 12. The weight of the filling unit (bottle body) is partially assigned to the support plate to bear the weight, so as to avoid serious deformation of the top of the conveyor belt 12.
[0032] A filling port (not shown) is provided at the top of the conveyor belt 12. When the conveyor belt 12 pushes the filling unit under the filling port, an infrared sensor is installed on the side baffle 1 of the conveyor belt 12 to locate the position of the bottle and the number of bottles passing through.

[0035] like Figure 3 As shown, in order to prevent the fixing effect of the central cylinder 2 from being deteriorated, the baffle 1 is provided with a supporting groove at the bottom of the limiting plate 21 to support the limiting plates 21 on both sides, thereby playing a role of positioning and supporting.
[0036] like Figure 1 and Figure 2 As shown, the secondary transverse feeding device includes a partition 3, a linkage plate 4 and an elastic reset member.

The linkage plate 4 is located within the travel range of the connecting plate 22. When the connecting plate 22 moves toward the conveyor belt 12, it contacts the linkage plate 4 or the partition 3, driving the partition 3 to move between the units of the filling group and compressing the elastic reset member. When the connecting plate 22 moves along the conveyor belt 12, the elastic reset member is released, driving the partition 3 away from the conveyor belt 12; an inverted L-shaped connecting plate 4122 is arranged between the rear side of the linkage plate 4 and the abutting compression section 34, one side of the inverted L-shaped connecting plate 4122 is connected to the linkage plate 4, and the other side of the inverted L-shaped connecting plate 4122 is connected to the partition 3.

The surface of the arc-shaped concave section 33 cooperates with the side wall of the filling group unit. The abutting compression section 34 protrudes from the rear side of the linkage plate 4 and cooperates with the connecting plate 22.
[0040] Working principle:
[0041] During the filling process, the conveyor belt 12 conveys the bottles to move forward, and the light sensor detects that a specified number of bottles have entered the bottom of the filling port. At this time, the cylinder 2 retracts to control the connecting plate 22 to move toward the conveyor belt 12. The telescopic plate 23 on the limiting plate 21 is pressed to the surface of the limiting plate 21 under the action of the limiting guide wheel 11. At this time, the connecting plate 22 contacts the abutting compression section 34 of the partition 3 extending from the rear side of the linkage plate 4. Under the action of the cylinder 2, the partition 3 is pushed forward and the elastic reset member is compressed until the partition 3 is inserted between adjacent bottles; at this time, the telescopic plate 23 on the limiting plate 21 is separated from the limiting guide wheel 11, and the bottle is clamped toward the middle, so that the bottle is in contact with the arc-shaped concave section 33, which has a good limiting effect; after the canning is completed, the cylinder 2 pushes the control connecting plate 22 away, the second spring 51 resets and controls the partition 3 to be separated, and at the same time, the limiting guide wheel 11 presses the telescopic plate 23 to retract, so that the bottle is separated from the limit, and finally the conveyor belt 12 moves the next group of filling groups under the filling port.
