[0001] The utility model relates to the technical field of liquid filling, in particular to a liquid filling dust-proof device. Background Art

[0002] The filling machine is mainly a small category of products in the packaging machine. From the perspective of packaging materials, it can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. From the degree of automation of production, it can be divided into semi-automatic filling machines and fully automatic filling production lines. Recently, with the QS certification of food, edible oil manufacturers have begun to pay attention to product quality and packaging. Therefore, the oil filling machine has become prominent in the filling machine. The filling machine can be divided into atmospheric pressure filling machines, pressure filling machines, liquid filling machines, oil filling machines, paste filling machines, sauce filling machines, granular slurry filling machines, powder filling machines, large bucket water filling machines, and vacuum filling machines according to the filling principle.

[0003] In the existing liquid filling equipment, generally, hydraulic transmission is used to drive the liquid to move inside the pipeline, and finally it is filled into the bottle or the inside of the packaging bag through the water outlet. However, in the use of the existing device, there will be a phenomenon that dust and the like fall into the bottle or the bottle mouth during filling, resulting in the unqualified liquid after filling. Moreover, if dust enters during the filling of liquids such as beverages, it is very unhealthy, and the filling efficiency is low.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] In view of the deficiencies and defects in the prior art that dust prevention cannot be achieved during filling in the above-mentioned background art.

[0006] A liquid filling dust-proof device disclosed by the utility model includes a connecting rod. Two sliding grooves are opened on the bottom surface of the connecting rod. The inner wall of each sliding groove is slidably connected with a sliding block. The bottom surface of each sliding block is fixedly connected with a connecting block one. A connecting rod is rotatably connected inside each connecting block one. The other end of each connecting rod is rotatably connected with a connecting block two. The front surface of each connecting block one is fixedly connected with a threaded block. A motor is arranged below the connecting rod. The output shaft of the motor is fixedly connected with a bidirectional threaded rod. The inner wall of each threaded block is threadedly connected with the outer surface of the bidirectional threaded rod. A discharge pipe is slidably connected inside the connecting rod. An irregular-shaped plate is fixedly connected to the outer surface of the discharge pipe. The bottom surface of each connecting block two is fixedly connected with the upper surface of the irregular-shaped plate. A spring is fixedly connected to the bottom surface of the irregular-shaped plate.

[0007] Further, the other end of the spring is fixedly connected with a dust-proof cover. The inner wall of the dust-proof cover is slidably connected with the outer surface of the discharge pipe. A pipeline is fixedly installed at the top end of the discharge pipe.

[0008] Further, two support frames are fixedly installed on the outer surface of the connecting rod. A workbench is arranged below the connecting rod, and a conveyor belt is fixedly installed on the upper surface of the workbench.

[0009] Further, through holes arranged at equal distances are formed in the front surface of the workbench, and a connecting pin is slidably connected to the inner wall of each through hole.

[0010] Further, a clamping plate is arranged above the workbench, and one surface of each clamping plate close to each other is fixedly connected to one end of the corresponding connecting pin away from each other.

[0011] Further, a limiting block and a screw rod are arranged inside the workbench, and the outer surface of the limiting block is fixedly connected to the inner wall of the corresponding through hole.

[0012] Further, the inside of the limiting block is threadedly connected to the outer surface of the screw rod, and the outer surface of the screw rod is threadedly connected to the inside of the corresponding connecting pin.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By arranging components such as a connecting rod, a threaded block, a bidirectional threaded rod, and a spring in the present utility model, the motor drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the threaded blocks to move relatively. The threaded blocks drive the sliding blocks to move inside the sliding grooves. The sliding blocks drive the first connecting block to move. The first connecting block drives the second connecting block to move downward through the connecting rod. At this time, the second connecting block drives the discharge pipe to move through the special-shaped plate. When the dust-proof cover contacts the bottle body, through the compression of the spring, at this time, the discharge pipe continues to move downward for filling. Thus, it realizes that the device can achieve the dust-proof effect during filling by rotating the bidirectional threaded rod and driving the cooperation between the dust-proof cover and the spring through the connecting rod, preventing dust from entering the bottle body and affecting the filling efficiency.

[0015] 2. By arranging components such as connecting pins, clamping plates, limiting blocks, and screw rods in the present utility model, by rotating the screw rod to rotate inside the limiting block, at this time, the screw rod drives the corresponding connecting pins to move inside the through holes. The connecting pins drive the corresponding connecting pins to move inside the through holes through the clamping plates. At this time, the clamping plates move relatively, and the distance between the clamping plates is adjusted according to the size of the bottle body. Thus, it realizes that the device can prevent the bottle body from tilting during filling by adjusting the distance between the clamping plates, facilitating the rotation of bottle bodies of different sizes, improving the applicability of the device and at the same time enhancing the filling efficiency.
