[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] (Example 1)

[0034] like Figs. 1 to 3 The filling and waste discharge device shown includes a filling needle 1, a waste discharge pipe 2, a first mounting plate 3, a second mounting plate 4, and a drive mechanism 5. The first mounting plate 3 and the second mounting plate 4 are arranged vertically. The filling needle 1 and the waste discharge pipe 2 are respectively mounted on the first mounting plate 3 and the second mounting plate 4, in equal numbers and in a one-to-one correspondence. Applied to a filling machine, the filling needle 1 and the waste discharge pipe 2 move closer and further apart longitudinally under the action of the filling machine's lifting mechanism; that is, the filling needle 1 descends or the waste discharge pipe 2 rises. Typically, the filling needle 1 descends in this field. The specific structure is a conventional design in this field and will not be described in detail here. A similar structure can be found in patent document CN110482459B. The overall design can achieve both coordination with the waste discharge pipe and diversified filling methods. The drive mechanism 5 is mounted on the second mounting plate 4 and is connected to the waste discharge pipe 2. The upper and lower ends of the waste discharge pipe 2 are offset horizontally, and the upper end is adapted to rotate relative to the lower axis of the waste discharge pipe 2 under the action of the drive mechanism 5, thereby enabling the upper end of the waste discharge pipe 2 to be positioned directly or offset below the needle of the filling needle 1. In the waste discharge state, the upper end of the waste discharge pipe 2 moves to directly below the filling needle 1, and the filling needle 1 descends through the lifting movement of the filling machine, thus inserting into the lower waste discharge pipe 2. In the non-waste discharge state, the upper end of the waste discharge pipe 2 moves to be offset away from the filling needle 1, providing space for the bottles to be filled and eliminating the need to disassemble the filling needle 1, thereby improving production efficiency.

[0035] Specifically, the first mounting plate 3 and the second mounting plate 4 are coaxially arranged annular plates. The filling needle 1 and the waste discharge pipe 2 are evenly arranged along the circumference of the first mounting plate 3 and the second mounting plate 4, respectively, and can be directly applied to rotary filling machines. The waste discharge pipe 2 includes an upper pipe 2-1, a middle pipe 2-2 and a lower pipe 2-3 arranged sequentially from top to bottom. The upper pipe 2-1 and the lower pipe 2-3 are both arranged vertically, and the middle pipe 2-2 is inclined downward. Both ends of the middle pipe 2-2 are rounded to the upper pipe 2-1 and the lower pipe 2-3, making the waste discharge smoother.

[0036] The shaft sleeve 6 is coaxially fixed on the lower tube 2-3 and is rotationally installed on the second mounting plate 4. The upper surface of the second mounting plate 4 is coaxially provided with an annular groove which does not penetrate the second mounting plate 4 near the inner ring, and the annular groove is rotationally provided with a swing ring 7. The swing ring 7 is uniformly and coaxially provided with a plurality of arc-shaped limiting grooves 7-1 which penetrate the swing ring 7, and at least one limiting groove 7-1 is provided with a limiting pin 8 which is fixed on the second mounting plate 4, so that the swing ring 7 is coaxially and rotationally arranged on the second mounting plate 4. The remaining limiting grooves 7-1 can be used to reduce the weight of the swing ring 7, so that the driving mechanism 5 can push the swing ring 7 more quickly and save time. Considering the reliability of the rotation of the swing ring 7, limiting pins 8 can also be arranged in the remaining limiting grooves 7-1 to avoid the failure of the limiting pins 8 due to wear and tear, which causes the swing ring 7-1 to lose the limit of movement. The driving mechanism 5 is a cylinder which is centrally symmetric and has two cylinders. The cylinder body is hinged to the second mounting plate 4 through a pin shaft structure, and the piston rod end is hinged to the swing ring 7 through a pin shaft structure. The swing ring 7 is stably pushed forward and reversed by the contraction and extension of the piston rod. In order to facilitate installation, the swing ring 7 is preferably arranged in multiple sections, and a plurality of arc-shaped sections are connected by connecting plates and bolts, which can be easily installed and disassembled. Each shaft sleeve 6 and the swing ring 7 are hinged to a connecting rod 9 through a pin shaft structure, so as to drive the waste pipe 2 to make reciprocating swing movement, and then the upper end of the waste pipe 2 is connected to or away from the filling needle 1. In actual application, by designing the arc length of the limiting groove 7-1, the swing size of the swing ring 7 can be accurately controlled, and the rotation amplitude of the waste pipe 2 can be controlled, so as to realize the accurate alignment of the waste pipe 2 and the filling needle 1.

[0037] The filter screen is installed at the lower end of the waste pipe 2 to prevent the bubbles generated by the waste liquid from flowing upward, i.e. toward the inlet of the waste pipe 2, causing secondary pollution to the outer wall of the filling needle. In addition, the cover part 2-4 is provided at the top of the upper tube 2-1, and the cover part 2-4 is provided with a through hole which is matched with the needle of the filling needle 1. The outer wall of the filling needle 1 is provided with a rubber sealing ring, so as to form a seal when cooperating with the waste pipe 2, thereby preventing the waste liquid from overflowing. The cover part 2-4 can effectively reduce the diameter of the waste pipe 2, thereby effectively preventing dust and other impurities from entering the waste pipe 2 when the waste pipe 2 is not in contact with the filling needle 1, and reducing the risk of clogging of the waste pipe 2. When the device is applied to filling in a sterile environment, the cover part 2-4 can be omitted to save costs.

[0038] The filling needle 1 and the waste discharge pipe 2 are close to or away from each other by using the existing structure, and the structure of the waste discharge pipe 2 is optimized, the upper end and the lower end of the waste discharge pipe 2 are designed as a staggered structure, and the upper end for receiving waste is driven to make a circular motion relative to the lower end under the driving of the driving mechanism 5 in transmission connection therewith, so that the filling needle 1 can be directly connected in the waste discharge state, the filling needle 1 does not need to be disassembled, and the filling needle 1 can be staggered away from the filling needle 1 in the non-waste discharge state, thereby providing space for the bottle body to be filled, and improving production efficiency.

[0039] The above specific embodiments further specifically describe the purpose, technical scheme and beneficial effects of the utility model, and it should be understood that the above description is only a specific embodiment of the utility model and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
