[0024] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,in, Figure 1 This is a structural schematic diagram of a preferred embodiment of a drip-proof one-way filling mechanism for a filling machine provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure inside the housing structure of the device shown; Figure 3 for Figure 2 A schematic structural diagram of the fastening structure shown; Figure 4 for Figure 1 The schematic diagram of the structure inside the discharge port shown includes a drip-proof one-way filling mechanism for a filling machine, including a device housing structure 1, a distance adjustment structure 2 is provided at the top end of the device housing structure 1, a tightening structure 3 is provided at the bottom end of the distance adjustment structure 2, and a sealing structure 4 is provided at the bottom end of the tightening structure 3;

[0026] The distance adjustment structure 2 includes a screw rod 201, and a bracket 202 is provided at the bottom end of the screw rod 201 via a rolling bearing;

[0027] The fastening structure 3 includes a plurality of pressurizing sleeves 301 disposed at the bottom end of the bracket 202 . The bottom ends of the plurality of pressurizing sleeves 301 are all connected with pressurizing slide bars 302 . The outsides of the plurality of pressurizing slide bars 302 are all sleeved with pressurizing springs 303 .

[0028] It should be noted that: the screw rod 201 rotates and moves up and down, causing the fastening structure 3 at the bottom end of the bracket 202 to move up and down. When the pressure is increased, several pressurizing sleeves 301 move down to squeeze the pressurizing spring 303, shortening the length of the pressurizing slide 302, thereby achieving the purpose of increasing the squeezing of the sealing float 401; when the pressure is reduced, several pressurizing sleeves 301 move up, the pressurizing spring 303 releases the elastic force, and extends the pressurizing slide 302, thereby achieving the purpose of reducing the squeezing of the sealing float 401.

[0029] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, the device shell structure 1 includes a device housing 101, a screw rod 201 is provided through the top of the device housing 101, a converging hopper 102 is provided at the bottom end of the device housing 101, a discharge port 103 is provided at the bottom end of the converging hopper 102, and a feed port 104 is provided at the bottom of one side of the device housing 101.

[0030] It should be noted that the equipment housing 101 is sealed to fill the material to prevent corrosion by external impurities, and the feed port 104 and the discharge port 103 are used for feeding and discharging respectively.

[0031] In the specific implementation process, refer to Figure 2 and Figure 3 As shown, a control handle 203 is provided on the top of the screw rod 201.

[0032] It should be noted that a control handle 203 is provided on the top of the screw rod 201, so that the control handle 203 can be raised externally to control the screw rod 201 to rotate.

[0033] In the specific implementation process, refer to Figure 3 and Figure 4 As shown, the sealing structure 4 includes a sealing float 401 arranged at the bottom end of several pressurized slide rods 302, and an insertion rod 402 is provided at the bottom end of the sealing float 401 corresponding to the discharge port 103. Sliders 403 are provided on both sides of the insertion rod 402. The two slides 403 are respectively slidably arranged in the corresponding slide grooves 404 opened inside the discharge port 103. Sealing rings are provided on the surrounding sides of the sealing float 401, and a rubber sleeve is sleeved on the outside of the insertion rod 402.

[0034] It should be noted that: on the one hand, the sealing float 401 is moved down and closely attached to the converging hopper 102, and on the other hand, the insertion rod 402 is moved down and closely attached to the discharge port 103, thereby avoiding the problem of loose sealing behavior of a single sealing structure, which leads to leakage or backflow of the filling material. The two sliders 403 are respectively slidably arranged in the corresponding slide grooves 404 inside the discharge port 103, which can limit the rotational displacement of the sealing float 401 and the insertion rod 402 when they slide up and down, thereby improving the sealing accuracy.

[0035] The working principle of the anti-drip one-way filling mechanism for a filling machine provided by the utility model is as follows:

[0036] When the bottle is in use, the filling material enters the collecting hopper 102 through the feeding port 104 and impacts the bottom side of the sealing float 401. When the buoyancy is too large, the sealing float 401 and the insertion rod 402 are lifted up to pass through the discharge port 103. In order to prevent the filling material from flowing back, the screw rod 201 is controlled to rotate up and down by controlling the handle 203, so that the fastening structure 3 at the bottom end of the bracket 202 moves up and down. When the pressure needs to be increased, several pressure sleeves 301 move down to squeeze the pressure spring 303, shorten the length of the pressure slide 302, and achieve the purpose of increasing the squeezing of the sealing float 401; when the pressure needs to be reduced, several pressure sleeves 301 move up, the pressure spring 303 releases the elastic force, and extends the pressure slide 302, so as to reduce the squeezing of the sealing float 401, ensure that the sealing float 401 moves down and is in close contact with the collecting hopper 102, and the insertion rod 402 moves down and is in close contact with the discharge port 103, so as to achieve the purpose of double sealing and anti-backflow.

[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
