Description

Technical Field

[0001] This invention relates to the field of chili sauce production technology, specifically to an automatic chili sauce filling machine. Background Technology

[0002] There are various types of chili sauce filling equipment available on the market. As the core equipment for efficiency and quality control in chili sauce production enterprises, a safe, efficient and hygienic chili sauce filling device is particularly important.

[0003] For example, Chinese patent publication number "CN220865726U" discloses "a chili sauce filling device," whose main structure includes a base and a spring bracket vertically fixedly connected to the upper side of the base. A telescopic rod is fixedly connected to the lower side of the spring bracket, and a wedge is movably connected to one side of the telescopic rod. A spring is fixedly connected to one side of the spring bracket, and a push rod is slidably connected to one end of the spring through the upper side of the spring bracket. Multiple small holes for adjusting the horizontal distance of the wedge are opened on one side of the push rod, and a drive mechanism for reciprocating left and right is provided on one side of the wedge. The device employs a moving cam mechanism. At the end of the push rod furthest from the cam mechanism, a filling mechanism is slidably connected to the push rod. During operation, the chili sauce filling device uses a servo motor to rotate the main gear, which in turn drives the secondary gear. The secondary gear, via a transmission shaft, drives the cam. The cam, in conjunction with a spring, pushes the push rod forward, discharging the sauce from the horizontal tube. Simultaneously, it compresses the spring to store elastic potential energy. This stage eliminates energy consumption and reduces sauce production costs. In the next stage, the elastic potential energy enables the chili sauce to be drawn from the material cylinder into both the vertical and horizontal tubes.

[0004] It is evident that the aforementioned chili sauce filling device relies on a reciprocating pusher to adsorb and discharge the chili sauce. This method has the following drawbacks: 1. The pusher's adsorption relies on gas suction to draw the chili sauce into the horizontal tube. However, gas adsorption makes it easier for a large amount of liquid in the chili sauce to rush in. Therefore, the discharged chili sauce will have obvious stratification between liquid and chili, resulting in an excessively large difference in the ratio of chili to liquid in the finished product. 2. During the process of the pusher drawing in the chili sauce, since there is no external force interfering with it, it must rely on its own gravity and gas suction to slowly draw the chili sauce into the horizontal tube. Therefore, it will cause a decrease in production efficiency. Furthermore, the pusher can only fill the chili sauce once in one cycle of reciprocating motion, which further reduces its production efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic chili sauce filling machine. Utilizing two symmetrical, reciprocating pistons, the machine enables two separate fillings of chili sauce during a single crankshaft rotation, thereby improving equipment efficiency. Furthermore, the device uses the rotation of a screw to store energy in the chili sauce, allowing it to quickly enter the space occupied by the two pistons, further enhancing efficiency. Simultaneously, the screw's energy storage ensures the chili sauce is filled in a stable proportion, improving the quality of the finished product and solving the aforementioned technical problems.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2An automatic filling machine for producing chili sauce includes a bottom fixed base plate 1, a top support base plate 2 located directly above the bottom fixed base plate 1, and a component mounting port 3 disposed inside the top support base plate 2. The bottom fixed base plate 1 is fixedly installed on the worktable by bolts, and then the rotor of an external servo motor is connected to the coupling 511. Then, the chili sauce is poured into the interior of the vertical storage chamber 42 through the feeding port 44.

[0021] To enable the mixing and pressure output of the chili sauce, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 and Figure 4 A rotary conveying mechanism 4 is required, which includes a vertical storage shell 41 with some parts fixed in the component mounting port 3 for storing chili sauce, a screw 49 installed inside the vertical storage shell 41 for stirring and directional driving of the chili sauce, and a drive motor 48 for rotating the screw 49. By starting the drive motor 48 and controlling the rotation direction of its rotor, the screw 49 can be directionally rotated. When the rotation of the screw 49 produces an upward driving effect, the chili sauce inside the vertical storage chamber 42 will be stirred. Conversely, when the rotation of the screw 49 produces a downward driving effect, the chili sauce will move into the screw 49 with a certain pressure and finally enter the three-way flow hole 515 with a certain pressure, forming an energy storage and conveying state, thereby realizing the stirring and pressure output function of the chili sauce.

[0022] For details regarding the specific structure of the rotary conveying mechanism 4, please refer to [link / reference]. Figure 3 and Figure 4 The system includes a vertical storage cavity 42 located inside a vertical storage shell 41 with an open top. A horizontal support 43 is fixedly installed at the top opening of the vertical storage cavity 42 on the vertical storage shell 41. The gap between the horizontal support 43 and the inner circumferential wall of the vertical storage shell 41 forms a feeding port 44. An inverted drive motor 48 is fixedly installed on the upper surface of the horizontal support 43 through a motor fixing shell 47.

A screw 49, which is located inside the vertical storage cavity 42 and the curved connecting channel 46, is fixedly installed at the rotor end of the drive motor 48. There is a gap between the edge of the screw 49 and the inner circumferential wall of the curved connecting channel 46, and this gap is insufficient to allow the chili sauce particles to flow longitudinally.

[0023] To enable rapid filling of chili sauce, please refer to [link / reference].

When the servo motor is started, the symmetrical crankshaft 510 will rotate. When the symmetrical crankshaft 510 rotates, it will cause the two pistons 55 to reciprocate in a staggered manner. That is, one piston 55 moves upward and the other piston 55 moves downward. The upward-moving piston 55 will cause the chili sauce to enter the corresponding raw material pushing chamber 54, thus introducing the chili sauce. The downward-moving piston 55 will cause the chili sauce in the corresponding raw material pushing chamber 54 to be discharged outward through the corresponding filling channel 513. The operator can select to open the corresponding ball valve 514 by observing the rotation of the symmetrical crankshaft 510, so as to fill the chili sauce into the tank, thereby realizing the rapid filling function of chili sauce.

[0024] For the specific structure of the reciprocating plug filling mechanism 5, please refer to [link / reference]. Figure 5 and Figure 6It includes two symmetrical longitudinal hollow tubes 51, which are fixedly connected by a fixed base 52. The top area of ​​the fixed base 52 is provided with a first shaft mounting hole 53. A rotatable symmetrical crankshaft 510 is mounted inside the first shaft mounting hole 53 of the fixed base 52 via bearings. A coupling 511 is fixedly mounted at each end of the symmetrical crankshaft 510. Two staggered symmetrical transverse shaft portions of the symmetrical crankshaft 510 are mounted in the sleeve holes of two bushings 59 via bearings.

An insertion limiting cavity 512 is provided at the center of the bottom end of the raw material pushing cavity 54 of each longitudinal hollow tube 51. The bottoms of two longitudinal hollow tubes 51 are fixedly connected by a three-way pipe 517.

The three-way pipe 517 has a flow check valve 516 installed in the internal space near the two insertion limiting cavities 512. The flow check valve 516 can control the material to flow unidirectionally into the insertion limiting cavity 512. The longitudinal hollow pipe 51 has a filling channel 513 for discharging material at the bottom end of the insertion limiting cavity 512. A ball valve 514 that can control the flow state of the material is installed in the filling channel 513.

The upper surface of each piston body 55 is provided with a hemispherical mounting cavity 57 for placing the rotating ball head 518. When the symmetrical crankshaft 510 rotates, it can drive the two piston bodies 55 to produce an up-and-down misaligned reciprocating driving phenomenon. The structural radius of the hemispherical mounting cavity 57 matches the structural radius of the rotating ball head 518, and the depth of the hemispherical mounting cavity 57 is greater than the structural radius of the rotating ball head 518 and less than the structural diameter of the rotating ball head 518.

[0025] To enable the adjustment of the filling height position, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 7 and Figure 8A filling height adjustment mechanism 6 needs to be set up. Internally, it includes a first external threaded rod 66 and a second external threaded rod 67 capable of relative movement; a longitudinal threaded sleeve 61 threadedly connected to the first and second external threaded rods 66 and 67, which changes the distance between them during rotation; and a polygonal limiting rod 611 inserted at the axis of the first and second external threaded rods 66 and 67 to prevent relative rotation. Rotating the longitudinal threaded sleeve 61, due to the threaded connection and the opposite threaded structure, and under the action of the polygonal limiting rod 611, changes the distance between the first and second external threaded rods 66 and 67, thereby controlling the longitudinal distance between the bottom fixed base plate 1 and the top support base plate 2. This change in longitudinal distance alters the height of the filling channel 513, thus achieving the function of adjusting the filling height position.

[0026] For details regarding the specific structure of the filling height adjustment mechanism 6, please refer to [link / reference]. Figure 7 and Figure 8 The system includes a longitudinal threaded sleeve 61, a first external threaded rod 66, and a second external threaded rod 67. One end of the longitudinal threaded sleeve 61 has a first internal threaded cavity 62 with a concave structure, and the other end has a second internal threaded cavity 63 with a concave structure. The rod of the first external threaded rod 66 is installed inside the first internal threaded cavity 62 via a first thread structure 64, and the rod of the second external threaded rod 67 is installed inside the second internal threaded cavity 63 via a second thread structure 65. The first and second external threaded rods 66 and 67 have concave polygonal limiting cavities 610 at their opposite ends. A polygonal limiting rod 611, inserted into the polygonal limiting cavity 610, is fixedly installed at the center of the longitudinal threaded sleeve 61. One end of the first external threaded rod 66 has an integral structure and is fixedly connected to the upper surface of the bottom fixed base plate 1. The first connecting plate 68 is connected to the second external thread rod 67. One end of the second external thread rod 67 is provided with a second connecting plate 69, which is integral with the second connecting plate 69 and fixedly connected to the bottom surface of the top support base plate 2. The cross-sectional shape of the polygonal limiting cavity 610 is consistent with the cross-sectional shape of the polygonal limiting rod 611, both being polygonal structures. The cross-sectional dimensions of the polygonal limiting cavity 610 match the cross-sectional dimensions of the polygonal limiting rod 611. The first thread structure 64 includes an internal thread structure disposed inside the first internal thread cavity 62 and an external thread structure disposed on the first external thread rod 66. The second thread structure 65 includes an internal thread structure disposed inside the second internal thread cavity 63 and an external thread structure disposed on the second external thread rod 67. The helical direction of the first thread structure 64 is opposite to that of the second thread structure 65.

[0027] In use, the bottom fixing base plate 1 is fixedly installed on the workbench with bolts. Then, the rotor of an external servo motor is connected to the coupling 511. Chili sauce is then poured into the vertical storage chamber 42 through the feeding port 44. The drive motor 48 is started, and its rotor rotation direction is controlled, which causes the screw 49 to rotate in a specific direction. When the rotation of the screw 49 produces an upward driving effect, the chili sauce inside the vertical storage chamber 42 will be stirred. Conversely, when the rotation of the screw 49 produces a downward driving effect, the chili sauce will move into the screw 49 with a certain pressure and finally enter the three-way flow hole 515 with a certain pressure, forming an energy storage and conveying state. When the servo motor is started, the symmetrical crankshaft 510 will rotate. When the symmetrical crankshaft 510 rotates, it will cause the two pistons 55 to reciprocate in a staggered manner. That is, one piston 55 moves upward and the other piston 55 moves downward. The upward-moving piston 55 will cause the chili sauce to enter the corresponding raw material pushing chamber 54, thus introducing the chili sauce. The downward-moving piston 55 will cause the chili sauce in the corresponding raw material pushing chamber 54 to be discharged outward through the corresponding filling channel 513. By observing the rotation of the symmetrical crankshaft 510, the operator can select to open the corresponding ball valve 514 to fill the chili sauce into the tank.
