DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0046] Embodiment 1

[0047] Referring to Figures 1-9 Fig. 1, a canning mechanism comprises: a first driving assembly 1, a valve assembly, and a plurality of canning channels 3.

[0048] The valve assembly is provided with a plurality of outlet channels 21 corresponding to the plurality of canning channels 3.

[0049] The first driving assembly 1 drives the valve assembly to move to a first attitude or a second attitude.

[0050] When the valve assembly is in the first attitude, the outlet channel 21 is not in communication with the canning channel 3.

[0051] When the valve assembly is in the second attitude, the cross section of the outlet channel 21 completely covers the cross section of the canning channel 3.

[0052] Product canning requires attention to both canning efficiency and canning quality. Canning quality refers to the ability to deliver an equal amount of material into each container.

[0053] To ensure filling efficiency, a large storage tank 5 is typically connected to multiple filling channels 3. Each filling channel 3 is equipped with a valve. The valve closes before the container aligns with the filling channel 3, and opens after alignment, allowing material to enter the container. Currently, the valves in the filling mechanism are solenoid valves, controlled by a controller to open or close multiple valves synchronously. This places high demands on the quality of the solenoid valves, as different valves have different actual flow areas when open. Valves used for a long time are more prone to wear or impurities causing inconsistent flow areas when open. Such minor filling inconsistencies are difficult for equipment to detect and can only be identified through product quality inspection. However, for consumers, receiving an underfilled product will create a negative impression of the product and the brand, potentially leading to a refusal to purchase that brand's product in the future. Therefore, filling consistency is a guarantee of product quality and the simplest and most direct indicator of product quality.

[0054] In this regard, this application provides a filling mechanism that ensures that the flow area of ​​each valve is the same after they are opened synchronously.

[0055] The filling mechanism in this embodiment includes multiple filling channels 3. One end of each filling channel 3 is connected to the storage bin 5 of the production line, and the other end is connected to a valve assembly. The valve assembly has multiple discharge channels 21 corresponding to the filling channels 3. The first driving component 1 drives the valve assembly to move to a first or second position. Since the discharge channels 21 are located within the valve assembly, the relative positions of each discharge channel 21 do not change. Therefore, when one discharge channel 21 is aligned with a filling channel 3, the remaining discharge channels 21 will also be aligned with the filling channel 3.

[0056] The valve assembly has two postures. In the first posture, the discharge channel 21 and the filling channel 3 are not connected. Specifically, the disconnection can be achieved by completely misaligning the discharge channel 21 and the filling channel 3 without changing the direction of the discharge channel 21, or by rotating the orientation of the discharge channel 21 to disconnect the two.

[0057] When the valve assembly is in the second position, the second position is not only a communication relationship between the discharge channel 21 and the filling channel 3, but also a relationship in which the ports of the two channels simply overlap to be in communication, and the area of the overlap reaches the maximum range as the position of the channel changes, that is, the cross section of one channel completely covers the cross section of the other channel. Therefore, the cross section of the discharge channel 21 completely covers the cross section of the filling channel 3, and the cross-sectional area of the filling channel 3 is taken as the flow area, so that the flow area is equal to the area of the filling channel 3 when the valve assembly is in the second position. For example, the diameters of the discharge channel 21 and the filling channel 3 are equal, and then the cross section of the discharge channel 21 wants to completely cover the cross section of the filling channel 3, and then the two must be in a coaxial position relationship. If the diameter of the discharge channel 21 is smaller than the diameter of the filling channel 3, then the cross section of the discharge channel 21 can never completely cover the cross section of the filling channel 3. If the diameter of the discharge channel 21 is greater than the diameter of the filling channel 3, then a certain displacement or deflection between the two can be allowed.

[0058] In the embodiment, the channels of the plurality of valves, that is, the discharge channels 21, are arranged in one workpiece, and each discharge channel 21 moves synchronously when the workpiece moves, so as to ensure that equal amounts of material are added to each container and the consistency of filling is ensured. Moreover, only the first driving assembly 1 can fail in the present application, and when the device fails, the maintenance personnel do not need to check each valve and directly repair the first driving assembly 1.

[0059] Further, the filling mechanism in the embodiment further includes a second driving assembly 6, and the second driving assembly 6 has a plurality of plunger heads 61 corresponding to the plurality of filling channels 3.

[0060] After the valve assembly enters the second position, the plunger head 61 pushes the material in the discharge channel 21 to flow out.

[0061] The present application mainly aims at filling semi-solid materials, such as Laoganma. The semi-solid materials have poor flowability, the second driving assembly 6 is arranged, the plunger head 61 is arranged in the second driving assembly 6, the plunger head 61 is aligned with the filling channel 3, the plunger head 61 is driven to move by a linear driving mechanism such as a pneumatic cylinder or a hydraulic cylinder, and when the valve assembly is in the second state, the second driving assembly 6 is started, and the plunger head 61 pushes the material out along the axis direction of the filling channel 3.

[0062] Embodiment 2

[0063] Referring to Figures 1-6 As shown in the figure, the valve assembly is provided with a plurality of guide barrels 22 and a plurality of sealing shaft bodies 23, which correspond to the plurality of filling channels 3.

[0064] The circumferential wall of the guide cylinder 22 is provided with an inlet port 221 and an outlet port 222, which are in communication with and coaxial with the port of the canning channel 3.

[0065] The sealing shaft body 23 is rotationally connected to the inside of the guide cylinder 22, and the side wall of the sealing shaft body 23 blocks the inlet port 221.

[0066] The outlet channel 21 penetrates the side wall of the sealing shaft body 23, and the first driving assembly 1 drives the rotation of the sealing shaft body 23.

[0067] The valve assembly provided by the embodiment includes a plurality of guide cylinders 22 and sealing shaft bodies 23 arranged inside the guide cylinders 22. The guide cylinders 22 are arranged below the canning channel 3. The side wall of the guide cylinder 22 is provided with an inlet port 221 and an outlet port 222. The inlet port 221 and the outlet port 222 are in communication with and coaxial with the canning channel 3. The material in the storage tank 5 can enter the inside of the guide cylinder 22 through the canning channel 3 and the inlet port 221. The guide cylinder 22 is provided with a sealing shaft body 23. The sealing shaft body 23 is rotationally connected to the guide cylinder 22. The side wall of the sealing shaft body 23 blocks the inlet port 221 of the guide cylinder 22, so that the material in the canning channel 3 cannot enter the guide cylinder 22 and cannot enter the external environment through the outlet port 222, that is, the material cannot leak out before the container is aligned with the outlet port 222. Meanwhile, the outlet channel 21 penetrates the side wall of the sealing shaft body 23, and the first driving assembly 1 drives the rotation of the sealing shaft body 23. For example, before the first driving assembly 1 is actuated, the outlet channel 21 is coaxial with the canning channel 3. At this time, the side wall of the sealing shaft body 23 is broken by the outlet channel 21, so that the inlet port 221 is in communication with the outlet channel 21. The material in the canning channel 3 can enter the container through the inlet port 221, the outlet channel 21, and the outlet port 222 in turn. At this time, the valve assembly is in the second pose. Then, the first driving assembly 1 drives the rotation of the sealing shaft body 23 around the axis of the guide cylinder 22 until the port of the outlet channel 21 is completely away from the inlet port 221. The side wall of the sealing shaft body 23 is in contact with the outlet port 222, so as to block the material. At this time, the valve assembly enters the first pose.

[0068] This embodiment provides a method for rotating the discharge channel 21 to allow the valve assembly to enter a first and second position. The discharge channel 21 is always located within the guide cylinder 22, effectively preventing material leakage (this application is mainly used for canning semi-solid materials, such as Lao Gan Ma chili sauce, primarily to prevent oil dripping). More importantly, this type of valve assembly occupies very little space; the dynamic sealing shaft 23 does not increase the spatial position of the valve assembly, reducing interference during equipment operation. Furthermore, the sealing shaft 23 and the guide cylinder 22 are rotatably connected (a bearing 8 is installed at the rotatable connection point), so the first drive assembly 1 only needs to drive the sealing shaft 23 to rotate, resulting in minimal resistance to the sealing shaft 23.

[0069] It is worth noting that the valve assembly is provided with multiple sealing shafts 23, for example, attached Figure 1 The filling device provides six sealing shafts 23. For each increase in the movement resistance of the sealing shaft 23, the first drive assembly 1 requires a six-fold increase in driving force, thus affecting the valve assembly's position switching. Furthermore, the higher the power of the drive assembly, the slower the switching. However, in this embodiment, the valve assembly with sealing shafts 23 only requires a low-power drive component 11, such as a cylinder, to achieve synchronous and rapid valve opening and closing.

[0070] Example 3

[0071] Reference Figure 2 , Figure 3 , Figure 7 As shown, further, to seal the inlet port 221, the side wall of the sealing shaft 23 can be made cylindrical, and the inner wall of the guide cylinder 22 can be made cylindrical. An annular sealing gasket 4 is placed between the outer cylindrical wall of the sealing shaft 23 and the inner cylindrical wall of the guide cylinder 22. The annular seal can be fixed to the inner wall of the guide cylinder 22. The inner circle of the annular sealing gasket 4 wraps around the inlet port 221. The annular sealing gasket 4 is squeezed by the outer cylindrical wall of the sealing shaft 23 and the inner cylindrical wall of the guide cylinder 22, thereby achieving sealing. The corresponding outlet port 222 can also be sealed with an annular sealing gasket 4.

[0072] It is worth noting that the edge of the discharge channel 21 port is prone to contacting the edge of the annular sealing gasket 4 during rotation, causing the annular sealing gasket 4 to peel off. This results in the sealing ring being squeezed into the mating gap between the sealing shaft 23 and the guide cylinder 22. This will not only cause the sealing shaft 23 to lose its sealing performance, but may also cause the entire first drive assembly 1 to jam, resulting in the entire equipment failing to operate.

[0073] Further, the outer circular edge and the inner circular edge of the annular sealing gasket 4 in the embodiment are provided with chamfered bevels 41, so that the cross section of the annular sealing gasket 4 is in a trapezoidal structure. It can be imagined that it is difficult to pick up a rubber pad with a trapezoidal cross section by pulling the bevel, because the bevel will convert a part of the horizontal force into a vertical force on the table, and the smaller the angle between the bevel and the horizontal plane, the more obvious the effect. The chamfered bevels 41 in the embodiment convert the vertical wall surfaces of the outer circle and the inner circle of the annular sealing gasket 4 into bevels, thereby greatly reducing the risk of peeling and lifting of the annular sealing gasket 4. Further, the rounded edges of the discharge channel 21 port are provided with chamfered bevels 41 to match the chamfered bevels 41 of the annular sealing gasket 4, which can better prevent the annular sealing gasket 4 from being peeled off.

[0074] Embodiment 4

[0075] With reference to Figures 1-6 As shown in the drawings, the first driving assembly 1 comprises a driving member 11, a loading member 12 and a plurality of rocker arms 13;

[0076] The plurality of rocker arms 13 correspond one-to-one to the plurality of sealing shaft bodies 23, and the loading member 12 is connected to the plurality of rocker arms 13;

[0077] One end of each of the rocker arms 13 is connected to the sealing shaft body 23, and the other end is rotationally connected to the loading member 12, and the rotation axis is parallel to the axis of the sealing shaft body 23;

[0078] The driving member 11 is used to drive the loading member 12 to move, thereby driving the plurality of rocker arms 13 to swing around the axis of the guide cylinder 22, so as to rotate the discharge channel 21 to the first pose or the second pose.

[0079] The final purpose of the present application is to realize the consistency of the valve opening size, thereby realizing the consistency of the canning.

[0080] The embodiment provides a first driving assembly 1 for synchronously moving a plurality of sealing shaft bodies 23.

[0081] Specifically, a plurality of rocker arms 13 are provided, each rocker arm 13 is connected to one sealing shaft body 23, and the rocker arm 13 is fixedly connected to the sealing shaft body 23, so that the rocker arm 13 can swing around the rotation axis of the sealing shaft body 23. Further, the loading member 12 is rotationally connected to each rocker arm 13, at this time, only the loading member 12 needs to be pushed to make each rocker arm 13 swing at the same time, and thus the sealing shaft body 23 rotates.

[0082] Meanwhile, the rocker arm 13 serves as a force-saving lever. Compared with directly driving the sealing shaft body 23 to rotate, the chain transmission mode, in which the sealing shaft body 23 is connected through a protruding part along the axis of the sealing shaft body 23, a gear is arranged in the connecting part, and a chain is arranged outside the plurality of gears to drive the gears, is more labor-saving and simpler in structure. The chain structure is complex and high in cost. In addition, the hinge of the chain (and the open belt) is prone to wear during rotation, which causes the pitch of the chain to increase and the pitch to be uncontrollable. Each chain link may serve as a rotation point for driving the gear, and the gears are driven at different angles by the chain links of different pitches. Therefore, it is difficult to control the rotation angle of the sealing shaft body 23, and the angle at which the discharge channel 21 enters the second position cannot be determined, so as to ensure that the flow area of the valve reaches the maximum.

[0083] The structure of the present application is extremely simple. The rocker arm 13 is fixedly connected to the sealing shaft body 23 and can be arranged in an integrated structure, or can be connected by screwing, clamping, clamping, welding or any other mode, as long as the rocker arm 13 and the sealing shaft body 23 do not rotate relative to each other. The other end of the rocker arm 13 is rotatably connected to the loading member 12. The rocker arm 13 protrudes a shaft into the hole of the loading member 12. A bearing 8 can be arranged in the hole of the loading member 12 to minimize the friction between the rocker arm 13 and the loading member 12 when they rotate relative to each other, thereby further reducing the load of the driving member 11.

[0084] More specifically, the axis of the sealing shaft body 23 protrudes to form a second connecting shaft 231, and the second connecting shaft 231 penetrates the end face of the guide cylinder 22.

[0085] The second connecting shaft 231 is a prismatic structure.

[0086] The rocker arm 13 is provided with a prismatic hole, and the prismatic hole is coupled with the side wall surface of the prismatic structure.

[0087] Inserting the prismatic structure into the hole coupled therewith can effectively prevent the sealing shaft body 23 and the rocker arm 13 from rotating relative to each other.

[0088] More specifically, the driving member 11 includes an extension part 111, and the free end of the extension part 111 is floatingly connected to the rocker arm 13, so that the free end of the extension part 111 can move in the first direction and can move in the second direction relative to the rocker arm 13.

[0089] The first direction is the extension direction of the extension part 111.

[0090] The second direction is a direction perpendicular to the first direction in the rotation plane of the sealing shaft body 23.

[0091] The trajectory of the rocker arm 13 during the swing is a circular arc, and the end of the rocker arm 13, or the part of the rocker arm 13 used to connect the loading member 12, has two displacement changes in two directions perpendicular to each other, i.e., a first direction and a second direction, the first direction being the telescopic direction of the telescopic part 111;

[0092] The second direction being the direction perpendicular to the first direction in the rotation plane of the sealing shaft body 23.

[0093] The driving member 11 must be fixed at a certain position to push the loading member 12 to move, and therefore the free end of the rocker arm 13 and the driving member 11 need to move in the first direction and the second direction simultaneously.

[0094] Two forms of floating connection are provided in the embodiment:

[0095] 1. The connecting hole 121 in the loading member 12 connected with the rocker arm 13 is a long hole, the depth direction of which is parallel to the axis of the sealing shaft body 23, and the length direction of which is parallel to the second direction. At this time, the rocker arm 13 can not only rotate relative to the loading member 12, but also can have a relative displacement, i.e., the shaft body of the rocker arm 13 slides along the length direction of the long hole. The loading member 12 is fixedly connected with the telescopic part 111, and at this time, the telescopic part 111 pushes the loading member 12 to move in the first direction, and the length direction of the long hole is the movement avoiding space for the first connecting shaft 131 to move in the second direction.

[0096] 2. The loading member 12 is hinged with the first connecting shaft 131, and the first connecting shaft 131 can only rotate, i.e., the loading member 12 synchronously moves in the first direction and the second direction with the first connecting shaft 131 of the rocker arm 13. Only one connecting hole 121 is provided in the loading member 12, which is a long hole used to connect the telescopic part 111, the depth direction of the long hole being parallel to the axis of the sealing shaft body 23, and the length direction of the long hole being parallel to the second direction. The free end of the telescopic part 111 is provided with a third connecting shaft 112, the third connecting shaft 112 being inserted into the long hole along the depth direction of the long hole, and the third connecting shaft 112 abuts against the inner wall surface of the long hole along the first direction, thereby pushing the loading member 12 and the first connecting shaft 131 of the rocker arm 13 to move in the first direction, and at the same time, the third connecting shaft 112 slides along the length direction of the long hole.

[0097] Embodiment 5

[0098] Referring to FIGS. 1-3, Figure 8 and Figure 9 As shown, the valve assembly is provided as a blocking plate 24, the plate surface of the blocking plate 24 facing the canning channel 3 being a blocking surface used to block the outlet of the canning channel 3;

[0099] The discharge channel 21 is perpendicular to the sealing surface and penetrates the sealing plate 24.

[0100] The first driving assembly 1 drives the sealing plate 24 to move along the direction of the sealing surface.

[0101] The embodiment provides another structure and manner for enabling the valve assembly to switch between the first position and the second position. The valve assembly is provided with only the sealing plate 24, the sealing plate 24 abuts against the plate surface of the canning channel 3 as the sealing surface, and the sealing surface is used for sealing the canning channel 3. Meanwhile, the discharge channel 21 is perpendicular to and penetrates the sealing plate 24. In the second position, the discharge channel 21 is aligned with the canning channel 3, and the first driving assembly 1 drives the sealing plate 24 to move along the direction of the sealing surface, so that the discharge channel 21 is completely dislocated from the canning channel 3, and the direction of the sealing surface is the direction perpendicular to the plane of the canning channel 3. In the embodiment, the first driving assembly 1 only needs to be capable of driving the sealing plate 24 to move linearly, which can be achieved by means of a lead screw transmission or hydraulic driving.

[0102] In the embodiment, all the discharge channels 21 are arranged in one part, thereby achieving absolute confirmation of the relative positions of the discharge channels 21 (the canning channels 3 are also fixedly arranged in one part), and there is no case that the flow areas of the communication channels are different after different discharge channels 21 are communicated with the canning channels 3, so that the cans can have good consistency (at least the problem of inconsistent cans caused by the valve assembly can be excluded).

[0103] Further, a ring-shaped sealing gasket 4 can be arranged in the end surface of the outlet of the canning channel 3, and the ring-shaped sealing gasket 4 can abut against the sealing surface to prevent the material from flowing out.

[0104] Embodiment 6

[0105] Referring to Figures 1-9 The canning device comprises the canning mechanism in any of the above embodiments and a storage tank 5.

[0106] The canning mechanism is provided with two, and when the canning channel 3 of one of the canning mechanisms is communicated with the storage tank 5, the discharge channel 21 of the canning mechanism enters the first position; and the discharge channel 21 of the other canning mechanism enters the second position.
