DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1 , Figure 2 As shown, a drip-proof filling mechanism of a filling machine comprises a filling tube 1, a filling inlet tube 2 is fixedly connected to the left side of the filling tube 1, a limiting sealing block 7 is fixedly connected to the inner cavity of the middle part of the filling tube 1, an anti-drip component 6 is clamped in the inner cavity of the limiting sealing block 7, a fixing plug 3 is clamped in the outer wall of the upper part of the anti-drip component 6 and the fixing plug 3 is located above the limiting sealing block 7, the outer wall of the fixing plug 3 is threadedly sleeved with the inner cavity of the filling tube 1, a connecting plate 4 is fixedly connected to the lower surface of the filling tube 1, and a filling protection component 5 is fixedly connected to the lower surface of the connecting plate 4;

[0029] Liquid enters the inner cavity of the filling tube 1 through the filling inlet tube 2. The weight of the liquid causes the anti-drip component 6 to operate, thereby opening the inner cavity of the filling protection component 5. Through the action of the filling protection component 5, the liquid is filled into the container below.

[0030] like Figure 3-Figure 6As shown, the filling protection component 5 includes a filling outlet pipe 53, the outer wall of the upper part of the filling outlet pipe 53 is fixedly connected to the inner cavity of the connecting plate 4, the outer wall of the lower part of the filling outlet pipe 53 is clamped with an anti-drip auxiliary component 52, and the left and right sides of the outer wall of the anti-drip auxiliary component 52 are clamped with two symmetrical fixing components 51, and the upper surfaces of the two fixing components 51 are respectively fixedly connected to the left and right parts of the lower surface of the connecting plate 4; the anti-drip auxiliary component 52 includes a rubber sealing sleeve 522, the inner wall of the rubber sealing sleeve 522 is overlapped with the outer wall of the lower part of the filling outlet pipe 53, the inner cavity of the rubber sealing sleeve 522 is fixedly connected with a fixing sleeve 521, the inner wall of the fixing sleeve 521 is clamped with the outer wall of the filling outlet pipe 53, and the lower surface of the rubber sealing sleeve 522 is fixedly connected with a filling outlet rubber pipe 523;

[0031] The rubber sealing sleeve 522 is used to seal the filling outlet tube 53 and the fixed sleeve 521, thereby ensuring that the liquid can be guided into the inner cavity of the filling outlet rubber tube 523 through the filling outlet tube 53. The filling outlet rubber tube 523 allows the anti-drip filling mechanism of the filling machine to be inserted into the entrance of the container during filling, thereby preventing impurities from entering during filling. At the same time, under the action of the rubber sealing sleeve 522 and the fixed sleeve 521, there is a certain degree of protection between the upper surface of the container and the anti-drip filling mechanism of the filling machine, thereby ensuring safe filling.

[0032] The fixing assembly 51 comprises a slide rail 511, the upper surface of which is fixedly connected to the lower surface of the connecting plate 4, the outer wall of the lower part of the slide rail 511 is slidably connected to a slider 512, the lower surfaces of the front and rear parts of the slider 512 are fixedly connected to telescopic rods 513, the outer walls of the two telescopic rods 513 are movably sleeved with connecting sleeves 515, the lower surfaces of the two connecting sleeves 515 are fixedly connected to clamping plates 516, the outer wall of a ring plate of a part of the clamping plate 516 close to the filling outlet pipe 53 is clamped with an annular groove provided on the outer wall of the upper part of the fixed clamping sleeve 521, the outer wall of the movable shaft of the lower part of the telescopic rod 513 is movably sleeved with a spring 1 514, and the upper and lower sides of the spring 1 514 are respectively fixedly connected to the upper part of the telescopic rod 513 and the opposite surfaces of the inner cavity of the connecting sleeve 515;

[0033] First, the fixed sleeve 521 is clamped onto the outer wall of the lower part of the filling outlet pipe 53. Under the action of the rubber sealing sleeve 522, the fixed sleeve 521 and the filling outlet pipe 53 are sealed and the fixed sleeve 521 is fixed under the filling outlet pipe 53. Then, by pulling the clamping plate 516, the clamping plate 516 moves downward under the action of the spring 1 514 and the telescopic rod 513. At this time, under the action of the slide rail 511 and the slider 512, the downwardly moved clamping plate 516 is moved to the outer wall of the fixed sleeve 521, so that the outer wall of the annular plate of a part of the filling outlet pipe 53 of the clamping plate 516 is clamped with the annular groove formed on the outer wall of the upper part of the fixed sleeve 521, so that the fixed sleeve 521 is fixed under the filling outlet pipe 53, so as to facilitate the quick disassembly and installation of the fixed sleeve 521 and the filling outlet rubber tube 523 for replacement, cleaning and maintenance.

[0034] An arc-shaped rubber pad 517 is fixedly connected to the upper surface of a portion of the annular plate of the clamping plate 516 close to the filling outlet pipe 53, and the upper surface of the arc-shaped rubber pad 517 overlaps the inner wall of the annular groove opened on the outer wall of the upper part of the fixed clamping sleeve 521;

[0035] Through the function of the arc-shaped rubber pad 517, the clamping plate 516 will not collide with the fixing sleeve 521 when restricting and fixing it, thereby increasing the service life.

[0036] like Figure 7 As shown, the anti-drip assembly 6 includes a fixed tube 61, the outer wall of the upper part of the fixed tube 61 is movably sleeved with the inner cavity of the lower part of the fixed plug 3, the outer wall of the lower part of the fixed tube 61 is movably sleeved with a sealing ring 71, and the outer wall of the sealing ring 71 is fixedly connected to the inner cavity of the limiting sealing block 7;

[0037] By rotating the fixing plug 3, the upper surface of the filling tube 1 is opened, so that the anti-drip assembly 6 can be quickly disassembled for replacement or maintenance, wherein the sealing ring 71 is used to seal the fixing tube 61 and the limiting sealing block 7.

[0038] The inner cavity of the fixed tube 61 is movably sleeved with a connecting rod 62, and a rubber sealing ball 65 is fixedly installed on the lower surface of the connecting rod 62. The outer wall of the rubber sealing ball 65 is clamped with the inner wall of the filling outlet tube 53. The upper surface of the connecting rod 62 is fixedly connected with a limiting circular plate 63, and the outer wall of the limiting circular plate 63 is movably sleeved with the inner cavity of the fixed tube 61. The lower surface of the limiting circular plate 63 is fixedly connected with a spring 2 64, and the inner wall of the spring 2 64 is movably sleeved with the outer wall of the connecting rod 62. The lower surface of the spring 2 64 is fixedly connected to the bottom of the inner cavity of the fixed tube 61;

[0039] When the liquid enters the inner cavity of the filling tube 1 through the filling inlet tube 2, the rubber sealing ball 65 moves downward to the inner cavity of the lower part of the filling outlet rubber tube 523 under the gravity of the liquid, so that the liquid can be filled into the container through the filling outlet rubber tube 523. After the filling is stopped, the spring 2 64 moves upward quickly due to the loss of pressure, so that the limiting circular plate 63 drives the connecting rod 62 and the rubber sealing ball 65 to move upward to the lower surface of the filling outlet tube 53 for sealing.

[0040] The rubber sealing ball 65 is made of rubber, and the lower center portion of the limiting circular plate 63 is funnel-shaped;

[0041] Since the lower center portion of the limiting circular plate 63 is funnel-shaped, the rubber sealing ball 65 can just engage with its inner wall when it moves upward under the action of the spring 64. Since the rubber sealing ball 65 is made of rubber, the lower surface of the filling outlet pipe 53 can be sealed to prevent leakage.

[0042] The working principle of the utility model is as follows: first, the fixed card sleeve 521 is clamped onto the outer wall of the lower part of the filling outlet pipe 53, and under the action of the rubber sealing sleeve 522, the fixed card sleeve 521 is sealed with the filling outlet pipe 53 and the fixed card sleeve 521 is fixed below the filling outlet pipe 53, and then the card plate 516 is pulled to move downward under the action of the spring 1 514 and the telescopic rod 513, and then the downward moving card plate 516 is moved to the outer wall of the fixed card sleeve 521 under the action of the slide rail 511 and the slider 512, so that the card plate 516 is close to the outer wall of a part of the annular plate of the filling outlet pipe 53 and the upper part of the fixed card sleeve 521. The annular groove on the outer wall is used for card connection, so that the fixed sleeve 521 is fixed under the filling outlet pipe 53. After the filling outlet rubber tube 523 is fixedly installed, when the liquid enters the inner cavity of the filling tube 1 through the filling inlet pipe 2, the rubber sealing ball 65 moves downward to the inner cavity of the lower part of the filling outlet rubber tube 523 under the gravity of the liquid, so that the liquid can be filled into the container through the filling outlet rubber tube 523. After the filling is stopped, due to the loss of pressure, the spring 2 64 moves upward quickly, so that the limiting circular plate 63 drives the connecting rod 62 and the rubber sealing ball 65 to move upward to the lower surface of the filling outlet pipe 53 for sealing.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
