DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1: Please refer to Figures 1 to 35. This embodiment provides a filling structure of a can sealing machine, including a feeding pipe 1 and a filling mechanism 2, which are connected and arranged together. The filling mechanism 2 includes a feeding chamber 21, and the feeding pipe 1 is connected to the feeding chamber 21, so that the food solution output by the feeding pipe 1 can enter the inside of the feeding chamber 21. A filling nozzle 22 is connected and arranged below the feeding chamber 21, and a lifting cylinder 23 is arranged above the feeding chamber 21. The lifting cylinder 23 is arranged on the top outer wall of the feeding chamber 21, and the piston rod end of the lifting cylinder 23 is arranged to penetrate into the feeding chamber 21 in a vertical downward movable manner, and a blocking block 24 for blocking the filling nozzle 22 is arranged on the penetration end of the piston rod end of the lifting cylinder 23. The blocking block 24 is arranged in a truncated cone structure, the small end of the blocking block 24 is fixedly connected to the piston rod end of the lifting cylinder 23, and the large end diameter of the blocking block 24 is arranged to be adapted to the inner diameter of the injection nozzle 22, so that when the large end of the blocking block 24 enters the injection nozzle 22, the injection nozzle 22 can be blocked to prevent the injection nozzle 22 from discharging material. At the same time, the blocking block 24 arranged in a truncated cone structure can avoid the phenomenon of subsequent food solution residue on the blocking block 24 as much as possible through the setting of its bevel. A reinforcing rib 6 is arranged between the bottom wall of the feed pipe 1 and the outer wall of the injection chamber, and the reinforcing rib 6 connects the bottom wall of the feed pipe 1 and the outer wall of the injection chamber together, and the setting of the reinforcing rib 6 plays a role in strengthening the connection strength between the feed pipe 1 and the injection chamber.

[0028] The feed pipe 1 is provided with a first defoaming component 3 for defoaming the food solution passing through the feed pipe 1. The first defoaming component 3 includes a first motor 31. The first motor 31 is fixedly arranged on the upper wall of the feed pipe 1 by setting a first mounting block 32. A first rotating shaft 33 movably inserted into the feed pipe 1 is fixedly connected to the electric spindle of the first motor 31. A defoaming knife 34 is arranged on the shaft wall of the first rotating shaft 33. The specific number and distribution of the defoaming knife 34 on the first rotating shaft 33 can be determined according to actual conditions.

[0029] Through the above-mentioned arrangement, before the feeding pipe 1 conveys the food solution to the feeding chamber 21, the first motor 31 is started. The first motor 31 works by driving the first rotating shaft 33 to rotate, which can drive the rotation of the defoaming knife 34. Then the feeding pipe conveys the food solution to the feeding chamber 21 again. At this time, the rotating defoaming knife 34 can shear the food solution in the feeding pipe 1 that passes through the defoaming knife 34, so as to break up the bubbles that may exist in the food solution and achieve defoaming. The food solution after shearing and defoaming by the defoaming knife 34 will enter the feeding chamber 21. The user controls the lifting cylinder 23 to perform appropriate work according to the needs, so that the blocking block 24 performs the appropriate action of moving out of the injection nozzle 22 or entering the injection nozzle 22 to perform the required injection and stop injection work. At this time, it is difficult for bubbles to exist in the food solution discharged from the injection nozzle 22, so as to ensure the accuracy of subsequent injection and the discharge speed of the injection nozzle 22.

[0030] Example 2: Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 This embodiment provides a filling structure of a can sealing machine, which is different from the first embodiment in that the first defoaming component 3 is replaced by a second defoaming component 5. Specifically, a breaking portion 4 is provided on the feed pipe 1, and a second defoaming component 5 is provided in the breaking portion 4. The second defoaming component 5 includes a centrifuge tube 51 provided in the breaking portion 4. Both ends of the centrifuge tube 51 are rotatably connected to the feed pipe 1 at both sides of the breaking portion 4 by providing a first bearing, so that the centrifuge tube 51 can be rotatably connected in the breaking portion 4. The setting of the centrifuge tube 51 satisfies that the food solution entering the feed pipe 1 can pass through the centrifuge tube 51 and then enter the filling mechanism 2. The feed pipe 1 is also provided with a driving component 54 for driving the centrifuge tube 51 to rotate.

[0031] The driving assembly 54 includes a second motor 540 fixedly arranged on the top surface of the feed tube 1 by setting a second mounting block 53, the second motor 540 is arranged on the feed tube 1 on one side of the centrifuge tube 51, and a connecting plate 541 is arranged on the top surface of the feed tube 1 on the other side of the centrifuge tube 51, a second rotating shaft 542 is arranged between the electric spindle of the second motor 540 and the connecting plate 541, one end of the second rotating shaft 542 is fixedly connected to the electric spindle of the second motor 540, and the other end is rotatably connected to the connecting plate 541 by setting a second bearing 54352, a pulley 544 is sleeved on the second rotating shaft 542, a belt groove 545 is arranged on the outer wall of the centrifuge tube 51, a transmission belt 546 is arranged between the pulley 544 and the centrifuge tube 51, and the transmission belt 546 can drive and connect the pulley 544 and the centrifuge tube 51 together by being sleeved on the pulley 544 and in the belt groove 545.

[0032] Through the above arrangement, before the feed pipe 1 conveys the food solution to the feed chamber 21, the second motor 540 is started. The second motor 540 drives the second rotating shaft 542 to rotate, thereby driving the pulley 544 to rotate, thereby rotating the centrifuge tube 51 through the transmission belt 546. After that, the injection tube transports the food solution into the feeding chamber 21. At this time, before the food solution enters the feeding chamber 21, it will enter the rotating centrifuge tube 51. The centrifuge tube 51 can centrifuge the food solution entering the centrifuge tube 51 through its own rotation, so that the bubbles that may exist in the food solution can be thrown to the tube wall of the centrifuge tube 51 to break them, thereby achieving defoaming. At the same time, the flow direction of the bubbles that may exist in the food solution can be made opposite to the flow direction of the food solution, so as to further ensure that there are almost no bubbles in the food solution that finally enters the feeding chamber 21. After the food solution after centrifugal defoaming in the centrifuge tube 51 enters the feeding chamber 21, the user controls the lifting cylinder 23 to perform appropriate work according to needs, and makes the blocking block 24 perform appropriate actions of moving out of the injection nozzle 22 or entering the injection nozzle 22, so as to perform the required injection and stop injection work.

[0033] Example 3: Please refer to Figures 1 to 4 and Figure 7 This embodiment provides a filling structure of a can sealing machine, which is different from the first and second embodiments in that: a first defoaming component 3 and a second defoaming component 5 are provided on the feed pipe 1 at the same time. The first defoaming component 3 and the second defoaming component 5 are arranged in sequence on the feed pipe 1 along the direction away from the feeding direction, so that the food solution input into the feed chamber 21 by the feed pipe 1 will first pass through the shear defoaming of the first defoaming component 3 and the centrifugal defoaming of the second defoaming component 5 in sequence, and then enter the feed chamber 21. Compared with the first and second embodiments, the double defoaming setting enables this embodiment to further ensure that there are almost no bubbles in the food solution that finally enters the feed chamber 21, and compared with the prior art, it has the advantages of ensuring the accuracy of filling and the speed of discharging.

Any equivalent structure or equivalent process transformation made by using the contents of the specification 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.
