[0007] In the above filling machine, the bottom of the mounting ring is provided with a guide slope and an avoidance groove at one end of the guide slope, and the mounting protrusion extends into the lower part of the mounting ring through the avoidance groove, so that the mounting ring is screwed to the mounting protrusion through the guide slope.

[0008] In the above filling machine, the mounting ring and the tube body are separate structures, the top of the tube body is provided with an annular limiting rib, and the annular limiting rib abuts against the top surface of the mounting ring; or, the mounting ring and the tube body are an integral structure.

[0009] In the above-mentioned filling machine, a lever is provided on the side of the mounting ring for pushing the mounting ring to rotate, and the lever and the mounting ring are an integrated structure.

[0010] In the above filling machine, the installation tube is sealingly sleeved on the bottom of the fixed tube, and the installation tube is locked on the fixed tube by the positioning piece.

[0011] In the above filling machine, the positioning member is a clamp, which clamps the outer side walls of the fixing tube and the installation tube at the same time, so that the installation tube is fixed to the lower end of the fixing tube.

[0012] In the above-mentioned filling machine, the positioning member includes a plurality of first clips provided on the outer wall of the fixed tube and a plurality of second clips provided on the outer wall of the mounting tube. The first clips are engaged with the second clips to lock the mounting tube on the fixed tube.

[0013] In the above filling machine, the filling head further includes a drainage pipe located above the loading platform, and the drainage pipe is connected to the fixed pipe to communicate with the cleaning chamber.

[0014] The beneficial effects of the present invention are:

[0015] A filling machine includes a loading platform and multiple filling heads mounted on the loading platform. The filling heads include a filling tube and a filling rod. The filling rod is mounted within the filling tube to control filling by opening and closing the bottom opening of the filling tube. The filling head also includes a sleeve, which is mounted on the outside of the filling tube to form a cleaning chamber with the bottom communicating with the filling tube. The sleeve includes a fixed tube mounted on the loading platform and a mounting tube sealed at the lower end of the fixed tube. The mounting tube is detachably connected to the fixed tube. This technical solution has the following technical effects:

[0016] The present invention forms a cleaning chamber between the sleeve and the filling tube by sleeve-arranging a sleeve on the outside of the filling tube. When cleaning is required, the bottom of the sleeve is closed by a blocking member. The cleaning water in the filling tube flows out from the bottom of the filling tube after washing the inner wall of the filling tube. Because the bottom of the sleeve is closed, the water flows into the cleaning chamber under the obstruction of the blocking member and flows from the bottom of the cleaning chamber to the top of the cleaning chamber to clean the outer wall of the filling tube at the tube mouth. Finally, the water is discharged from the cleaning chamber through a drainage structure connected to the sleeve, thereby realizing self-cleaning of the filling head. It can clean both the inside of the filling tube and the outer wall of the tube mouth of the filling tube, ensuring the cleanliness and sterility of the filling head. By configuring the sleeve as a detachably connected mounting tube and a fixed tube, the staff only needs to remove the mounting tube sleeved on the lower end of the filling tube to replace the filling rod inside the filling tube, which is convenient for the staff to select different filling rods according to the type of filling liquid, reducing the difficulty of operation and improving the operation efficiency.

[0017] The mounting tube is sealingly sleeved on the bottom of the fixed tube, and the mounting tube is locked on the loading platform by a locking piece. The mounting tube is detachably connected to the bottom of the loading platform by the locking piece, so that the mounting tube and the fixed tube are firmly connected. The mounting tube is sealingly sleeved on the bottom of the fixed tube in the assembled state to ensure the sealing between the two. By loosening the mounting tube and the locking piece, the mounting tube can be removed to replace the mounting tube and the filling rod inside the filling tube. The operation is convenient and simple, which improves the user experience.

[0018] The locking elements consist of multiple vertical mounting rods surrounding the sleeve. The tops of the mounting rods are fixed to the bottom of the platform, and the bottoms of the mounting rods are equipped with mounting protrusions that protrude toward the mounting tube. The mounting tube comprises a tube body and a mounting ring located on the outer circumference of the tube body. The bottom surface of the mounting ring abuts against the top surface of the mounting protrusions. By providing mounting rods at the bottom of the platform to restrain the mounting tube, the mounting tube is locked to the platform. Because the platform is strong and resistant to damage, the platform provides better support and restraint for the mounting rods and the mounting tube, ensuring a sealed connection between the mounting tube and the fixed tube.

[0019] The bottom of the mounting ring is equipped with a guide bevel and a relief groove at one end of the guide bevel. The mounting protrusion extends through the relief groove into the lower portion of the mounting ring, allowing the mounting ring to be screwed onto the mounting protrusion via the guide bevel. The guide bevel allows the rotating mounting ring to guide the mounting protrusion, which extends into the lower portion of the mounting ring through the relief groove, facilitating quick screwing of the mounting protrusion into place. During this screwing, the mounting ring simultaneously drives the tube body upward, allowing the top of the tube body to move upward and seal against the bottom of the fixed tube, creating a tighter seal.

[0020] A lever is provided on the side of the mounting ring for pushing the mounting ring to rotate. The lever and the mounting ring are an integrated structure and are used to push the mounting ring to rotate, which is convenient for operation and more labor-saving.

[0021] The installation pipe is sealed and sleeved on the bottom of the fixed pipe, and the installation pipe is locked on the fixed pipe through a positioning piece, which is convenient for installation and removal of the installation pipe.

[0022] The positioning piece is a clamp, which simultaneously clamps the outer walls of the fixed tube and the mounting tube to fix the mounting tube to the lower end of the fixed tube. When the mounting tube and the fixed tube are locked, the clamp simultaneously clamps the outer walls of the fixed tube and the mounting tube. The structure of the clamp is simple, and the mounting tube and the fixed tube are locked by the clamp, which makes it easy to install and disassemble.

[0023] The positioning member includes a plurality of first clips provided on the outer wall of the fixing tube and a plurality of second clips provided on the outer wall of the mounting tube. The first clips are engaged with the second clips to lock the mounting tube on the fixing tube, ensuring a firm connection and facilitating installation and disassembly.

[0024] The filling head also includes a drain pipe located above the loading platform. The drain pipe is connected to the fixed pipe to communicate with the cleaning chamber and is used to discharge the cleaning water in the cleaning chamber. By connecting the drain pipe to the outer wall of the fixed pipe, the cleaning water can flow fully from bottom to top in the cleaning chamber, and the filling liquid adhering to the outer wall of the filling tube mouth is fully cleaned to prevent bacteria from growing on the outer wall of the filling tube.

[0040] Example 1:

[0041] A filling machine, such as Figures 1 to 4As shown, it includes a loading platform 100 and a filling head. There are multiple filling heads, all of which are arranged on the loading platform 100 to perform filling operations on containers to be filled (such as packaging cups, etc.) located below the loading platform 100. The filling head includes a filling tube 200, a filling rod 210, a sleeve 300 and a drainage pipe 311. The filling rod 210 is arranged in the filling tube 200 to open and close the bottom opening of the filling tube 200 by moving up and down, thereby controlling the filling tube 200 to fill the container to be filled. The sleeve 300 is sleeved on the outside of the filling tube 200 to form a cleaning chamber 400 between the sleeve 300 and the filling tube 200. The sleeve 300 includes a fixing tube 310 and an installation tube 320. The fixing tube 310 is arranged on the loading platform 100. The fixed tube 310 is located at the upper end of the stage 100 and is fixed to the stage 100 by screws. The top end of the fixed tube 310 is sealed with the outer wall of the filling tube 200. The lower end of the fixed tube 310 passes through the stage 100 and extends out of the bottom surface of the stage 100. The mounting tube 320 is sealed and connected to the lower end of the fixed tube 310 to be plugged with the fixed tube 310 and together form a sleeve 300. The drain pipe 311 is located above the stage 100 and is connected to the fixed tube 310 so that the drain pipe 311 is connected to the cleaning chamber 400. The bottom opening height of the mounting tube 320 is lower than the bottom opening height of the filling tube 200, so that when the bottom opening of the mounting tube 320 is closed, the bottom of the inner cavity of the filling tube 200 is connected to the cleaning chamber 400.

[0042] In this embodiment, the mounting tube 320 is detachably connected to the bottom of the stage 100 via a locking piece, so that the mounting tube 320 is firmly connected to the fixed tube 310. The mounting tube 320 in the assembled state is sealed and sleeved on the bottom of the fixed tube 310 to ensure the sealing between the two. By loosening the mounting tube 320 from the locking piece, the mounting tube 320 can be removed to replace the mounting tube 320 and the filling rod 210 inside the filling tube 200. The operation is convenient and simple, which improves the user experience.

[0043] like Figure 1 As shown, the locking member includes a locking ring 110 and a plurality of mounting rods 120 vertically surrounding the circumference of the sleeve 300. The top of the mounting rod 120 is fixed to the locking ring 110, and the locking ring 110 is fixed to the bottom surface of the loading platform 100 to fix the mounting rod 120 to the loading platform 100. The bottom of the mounting rod 120 is provided with a mounting protrusion 121. The mounting protrusion 121 surrounds the circumference of the mounting rod 120 and protrudes from the side wall of the mounting rod 120. When the mounting rod 120 is rotated to any angle, the mounting protrusion 121 always protrudes toward the mounting tube 320 to provide support for the mounting tube 320, making installation more convenient. Of course, the mounting rod 120 in this embodiment can also be directly fixed to the bottom surface of the loading platform 100.

[0044] like Figure 2As shown, the mounting tube 320 comprises a separate body 321 and a mounting ring 322. The top of the body 321 is provided with an annular retaining rib 3211 that surrounds the body 321 and protrudes from the outer wall of the body 321. The mounting ring 322 is sleeved over the body 321, with the top of the mounting ring 322 abutting against the bottom of the annular retaining rib 3211. A guide slope 3221 is provided on the bottom surface of the mounting ring 322, and a relief groove 3222 is provided on the mounting ring 322, opening outwards. The relief groove 3222 is located at one end of the guide slope 3221. A lever 3223 is also provided on the side of the mounting ring 322. The lever 3223 is integral with the mounting ring 322 and is used to rotate the mounting ring 322, facilitating operation and reducing effort. By setting a mounting rod 120 at the bottom of the workbench 100 to limit the mounting tube 320, the mounting tube 320 is locked on the workbench 100. Because the workbench 100 is relatively strong and not easily damaged, the workbench 100 has a better supporting and limiting effect on the mounting rod 120 and the mounting tube 320, thereby ensuring a sealed connection between the mounting tube 320 and the fixed tube 310.

[0045] In this embodiment, the mounting ring 322 and the tube body 321 are provided as separate structures, which facilitates production and processing. When the mounting ring 322 or the tube body 321 is damaged, they can be replaced separately, thereby reducing maintenance costs. Of course, it is understandable that the mounting ring 322 and the tube body 321 in this embodiment can also be an integrated structure.

[0046] When the mounting tube 320 needs to be assembled with the fixing tube 310, the mounting ring 322 is first sleeved on the outer peripheral side of the tube body 321 so that the top of the mounting ring 322 abuts against the bottom of the annular limiting rib 3211. Then, the lever 3223 is held to drive the mounting ring 322 and the tube body 321 to move upward. During the upward movement, the mounting ring 322 avoids the mounting protrusion 121 through the avoidance groove 3222 until the mounting ring 322 moves above the mounting protrusion 121. Then, the lever 3223 is rotated to drive the mounting ring 322 They rotate together so that the top surface of the mounting protrusion 121 abuts against the guide inclined surface 3221 and slides along the guide inclined surface 3221 from the side close to the avoidance groove 3222 to the side away from the avoidance groove 3222, and finally abuts against the bottom surface of the mounting ring 322, thereby realizing the screw connection between the mounting ring 322 and the mounting protrusion 121. During the screw connection process between the mounting ring 322 and the mounting protrusion 121, the mounting ring 322 drives the tube body 321 to move upward through the annular limiting rib 3211, so that the top of the tube body 321 moves upward and is sealed and sleeved on the bottom of the fixed tube 310. The mounting protrusion 121 at the bottom of the mounting rod 120 limits the mounting ring 322 sleeved on the outer peripheral side of the tube body 321 in the vertical direction, ensuring the sealing between the fixed tube 310 and the mounting tube 320. At the same time, the mounting protrusion 121 will not affect the mounting surface between the fixed tube 310 and the mounting tube 320, so that the mounting surface between the fixed tube 310 and the mounting tube 320 is a smooth curved surface with a good sealing effect, preventing the filling liquid from remaining on the mounting surface between the two, and ensuring the sterility requirements of the filling head.

[0047] When the filling machine is filling, the filling liquid flows out from the bottom of the filling tube 200 and flows into the container to be filled; after the filling machine has been running for a period of time, in order to ensure the sterile environment inside the filling head, it needs to be cleaned regularly. When cleaning is required, the shielding member in the filling machine closes the bottom of the installation tube 320. Because the bottom opening height of the installation tube 320 is lower than the bottom opening height of the filling tube 200, when the bottom of the installation tube 320 is closed, the bottom of the filling tube 200 is connected to the bottom of the cleaning chamber 400. After flushing the inner wall of the filling tube 200, the cleaning water in the filling tube 200 flows from the bottom of the filling tube 200 into the cleaning chamber 400, and flows from the bottom of the cleaning chamber 400 to the top of the cleaning chamber 400. The outer wall of the filling tube 200 at the tube mouth is cleaned, and finally the cleaning cavity 400 is discharged from the drain pipe 311 connected to the fixed tube 310 to realize self-cleaning of the filling head. It can clean the inside of the filling tube 200 and the outer wall of the tube mouth of the filling tube 200, ensuring the cleanliness and sterility of the filling head. By setting the sleeve 300 as a detachably connected mounting tube 320 and a fixed tube 310, the staff only needs to remove the mounting tube 320 sleeved on the lower end of the filling tube 200 to replace the filling rod 210 inside the filling tube 200, so that the staff can choose different filling rods 210 according to the type of filling liquid, thereby reducing the difficulty of operation and improving the operation efficiency.

[0048] Example 2:

[0049] The difference between this embodiment and the first embodiment is that, in this embodiment, the mounting tube is locked on the fixed tube by a positioning piece, and the positioning piece is a clamp. When the mounting tube and the fixed tube are locked, the clamp simultaneously clamps the outer side walls of the fixed tube and the mounting tube, and the mounting tube and the fixed tube are locked by the clamp. The structure of the clamp is simple and easy to install and disassemble.

[0050] Example 3:

[0051] The difference between this embodiment and embodiment 2 is that, in this embodiment, the positioning member includes multiple first clips and second clips, the first clips are arranged on the outer wall of the fixed tube, and the second clips are arranged on the outer wall of the mounting tube. When the mounting tube is sleeved on the lower end of the fixed tube, the first clips and the second clips are engaged to lock the mounting tube on the fixed tube, which ensures a stable connection and is easy to install and disassemble.

[0052] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
