A through hole 710 is arranged on a partition wall between the liquid outlet passage 709 and the left bin, as shown in fig. 5-6, a mounting ring 711, a conical spring 712, a sliding plug 713, a bearing sleeve 714, a fixing plug 717 and a conical plug 716 are sequentially fixed in the through hole 710 from left to right, the large end of the conical spring 712 is fixedly connected to the end surface of the mounting ring 711, the small end of the conical spring 712 is fixedly connected to the center of the end surface of the sliding plug 713, the sliding plug 713 is fixedly connected to the small end of the conical plug 716 through a sliding rod 715 which is inserted into the bearing sleeve 714 in a sliding fit manner, a conical hole communicated with the top of the liquid outlet passage 709 is formed in the fixing plug 717, and the conical plug 716 can be plugged into the conical hole, so that in a non-working state, the conical plug 716 is plugged by elastic tension of the conical spring 712 to seal the conical hole of the fixing plug 717. The through hole 710 section between the sliding plug 713 and the fixing plug 717, to which the sliding plug 713 cannot slide, communicates with the right chamber through the drainage hole 718. More specifically, a suction pipe 15 provided with a submersible pump is further arranged in the right chamber, one end of the suction pipe 15 is positioned at the bottom of the right chamber, the other end of the suction pipe 15 extends into the drainage hole 718 and cannot be in contact with the inner wall of the drainage hole 718, and a liquid inlet pipeline 16 for feeding liquid food into the right chamber is connected to the right chamber close to the bottom of the right chamber and can be used for fully pumping away the liquid, and the liquid suction device is particularly suitable for liquid needing to be properly settled. When the filling switch 707 is pressed by the arc-shaped toggle plate 6, the piston rod 702 moves down in time to gradually open the liquid outlet passage 709, however, the compression spring 708 is required to be compressed by a certain distance in the horizontal section of the filling switch 707 to reduce the cavity inside the annular flange 706, so as to indirectly compress the left chamber, gradually increase the pressure in the left chamber, and push the conical plug to separate from the fixed plug 717 after the pressure in the left chamber is increased to a certain degree, thereby opening the passage between the right chamber and the liquid outlet passage 709. The above structural design is mainly that on the basis that the piston rod 702 controls the opening and closing of the liquid outlet channel 709, a pneumatic control switch is additionally arranged to control the connection and the disconnection of the right bin and the liquid outlet channel 709, so as to realize a double opening and closing mechanism of a liquid food liquid transportation line of a filling part, the pressing action of a filling switch 707 is realized, and simultaneously, the related double opening and closing modes of pneumatic and mechanical braking are realized.

In order to better realize the piercing filling of the filling needle 705 and ensure that the filling needle 705 can take the liquid food box 9 away from the clamping table 10 for continuous filling when the filling part retracts after penetrating into the filling neck 8, as shown in fig. 7, the neck hole of the filling neck 8 is a stepped blind hole 722 gradually reduced from top to bottom, the bottom of the stepped blind hole 722 is made of a pierceable material, especially a food-grade sizing material, a circle of sliding pins 719 capable of elastically expanding and contracting in the radial direction of the hole is circumferentially arranged on the hole side wall of the stepped blind hole 722, a limit ring 720 is coaxially and fixedly connected to the outer wall of the filling needle 705, when the filling needle 705 pierces the bottom of the stepped blind hole 722, the limit ring 720 extrudes the sliding pins 719 into the hole side wall and then moves downwards to be pressed by the sliding pins 719 ejected again when contacting with the step surface of the stepped blind hole 722, so as to fixedly connect the filling part and the liquid food box 9 together, the filling needle 705 moves back to take the liquid food cartridge 9 along with it. Further, in order to facilitate pulling the sliding pin 719 back into the hole sidewall, a pull string is connected to the end of the sliding pin 719 inside the hole sidewall, and the other end of the sliding pin 719 extends out of the filling neck 8 after passing through the clamp spring and is connected to a pull ring 721.

When the filling machine is used, the driving rods 4 and the transmission rods 5 which are arranged in tandem are driven in the circumferential direction of rotation and driven by the driving shaft 3, the driving rods 4 firstly and gradually poke and rotate oppositely to enable the driving disc 1 which is coaxially and fixedly connected and is arranged at a preset position to move in place together with the clamping table 10, then the arc-shaped poking plate 6 driven by the transmission rod 5 is gradually contacted and extruded with the filling switch 707 of the filling component 7 which moves downwards and vertically and approaches, due to the special structural design of the filling machine, when the driving shaft 3 further rotates, the arc-shaped poking plate 6 is closer and closer to and extrudes the filling switch 707 within a certain stroke, so that the arc-shaped poking plate 6 and the filling switch 707 gradually approach, contact and extrude until the filling switch 707 is finally and completely separated, and under the further synchronous rotation of the clamping table 10 along with the driving disc 1 and the upward retraction of the filling component 7 by the pushing device, the filling needle 705 is relatively far from the clamping table 10, and during this far process, the filling needle 705 directly takes away the liquid food cartridge 9 from the clamping table 10 due to the piercing connection with the filling neck 8, so that the liquid food in the filling assembly 7 can be filled into the liquid food cartridge 9 continuously in the subsequent process interval. It should be noted that the elastic and flexible filling needle 705 is controlled by the filling switch 707, and the filling needle 705 is inserted into the filling neck 8 by piercing while the filling switch 707 is pressed, and is filled by injection, so as to prevent the liquid food from leaking during filling, and further to simplify the filling process and the convenience of filling, because conventional filling requires that the filling tube is just inserted into the bottle mouth or box mouth, which is quite precise, but this piercing connection mode does not have the problem, and can pierce and fill at all pierceable positions inside the filling neck 8, and is particularly suitable for light and small liquid food, for example, the hole bottom of the stepped blind hole 722 in the above embodiment has a large hole bottom area, and the allowable movement range of the filling piercing can be large, not only has extremely low requirement on the precision of the filling action, but also can better realize sealing during filling.
