DETAILED DESCRIPTION

[0044] The technical solution of the present invention will be described below in conjunction with the accompanying drawings of the present invention.

[0045] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0046] Please see Figures 1 to 12 , Figure 1 The present invention provides an automatic filling system, which mainly includes an adjusting device 200, a pushing device 300 and a canning device 400. The adjusting device 200 is connected with a material trough 100, and the pushing device 300 and the canning device 400 are also connected to the adjusting device 200. The existing automatic filling system is compact, complex and inconvenient to install. During use, the filling accuracy will be affected due to the looseness or loss of parts.

[0047] In order to solve the above technical problems, the present invention has conducted in-depth research on the automatic filling system, and now the specific structure is described in detail. Figure 2 , 3 As shown in , the material tank 100 is provided with an agitator 110, and the agitator 110 is driven by the second driving motor 120 to continuously stir the material tank 100, so that the material (specifically chili sauce, bean paste, etc.) is evenly mixed in the material tank 100 without sedimentation. The material transmission must pass through the regulating device 200, and the regulating device 200 mainly includes a valve body assembly 210, a rotating assembly 220 and an regulating assembly 230, wherein the rotating assembly 220 is used to drive the valve body assembly 210 to rotate, so that the valve in the valve body assembly 210 is in a closed or open state, and the regulating assembly 230 is used to adjust the installation point of the rotating assembly 220, so that the rotating assembly 220 can always maintain the purpose of accurately regulating the valve body assembly 210.

[0048] The valve body assembly 210 is now specifically explained. It mainly includes a three-way valve core 211 and a valve housing 212. The shape is round. Compared with the existing square valve body assembly 210, it is easy to process, saves processing time, and reduces processing difficulty. Through research, it is found that the existing square valve body assembly 210 is directly installed on the filling bracket (that is, a whole mounting plate 235), so that the mounting point of the rotating assembly 220 of the control valve body assembly 210 can only be on the mounting plate 235. When the parts in the rotating assembly 220 are loose or damaged, it is not The mounting point can be adjusted in time. Since the mounting point cannot be adjusted, during long-term use, each component will become more seriously loose or damaged, which will cause the third cylinder 221 to be unable to push the rotating block 224 normally, so that the rotation stroke of the linked three-way valve core 211 will have serious errors, which will lead to the inability to accurately control the amount of material during the filling process. When the error accumulates to a certain extent, the valve of the three-way valve core 211 cannot be fully opened or closed, which will eventually affect the filling amount and dripping caused by the valve not being closed tightly. In the present invention, the installation method of the valve body assembly 210 is changed, and the valve body assembly 210 does not need to be fixedly connected to the bottom plate structure. Instead, the circular valve body assembly 210 is directly suspended, and the connection relationship between the valve body assembly 210 and the material trough 100 is changed, specifically to a hard connection. In addition, the connection relationship between the valve body assembly 210 and the adjusting device 200 and the pushing device 300 is also changed, and they are all set to be hard connections. The advantage of such a configuration is that the installation position of the rotating assembly 220 is not affected by the plate-like structure at the bottom.

[0049] In addition to the above-mentioned differences in shape and installation method from the existing valve body assembly 210, the surface of the three-way valve core 211 adopted by the present invention is also coated with a layer of tin. After coating with such a layer of material, the rotation between the three-way valve core 211 and the valve housing 212 is smoother, and burrs will not appear, thereby ensuring the accuracy of rotation.

[0050] A sealing ring 213 is provided on the three-way valve core 211 to prevent material leakage. In order to prevent material leakage, a stepped mounting portion is also provided at the end of the three-way valve, which cooperates with the groove on the connecting piece. The connecting piece is a component used to integrate the three-way valve core 211 and the valve housing 212 into one.

[0051] The end of the three-way valve core 211 is also provided with a protruding block 214 for connecting with the rotating assembly 220. The rotating assembly 220 includes a rotating block 224, a third cylinder 221, a telescopic rod 222, and an adapter 240, wherein the rotating block 224 is matched and connected with the protruding block 214, and the specific connection method is to open a placement groove on the rotating block 224, protrude and place it in the placement groove, and then fix it with a fixing bolt 225, and lock it with a locking bolt 226 on the side wall of the rotating block 224, so as to achieve the purpose of doubly fixing the protruding block 214.

[0052] The free end of the rotating block 224 is connected to the telescopic rod 222 through an adapter 240. The adapter 240 mainly includes an adapter bolt 241, an adapter ball 242 and an adapter block 243. The adapter ball 242 is sleeved on the adapter bolt 241, and the adapter block 243 is arranged between the adapter ball 242 and the rotating block 224. The end of the rotating screw is connected to the rotating block 224, and the adapter ring 223 on the telescopic rod 222 is sleeved on the adapter ball 242, so as to achieve the purpose of corresponding control of rotation. The present invention preferably uses the contact mode between the adapter ball 242 and the adapter block 243. This is because the wear during the rotation process of the ball and the surface contact is smaller, which is beneficial to extend the service life of the components.

[0053] As mentioned above, the installation method of the rotating assembly 220 has an important influence on whether the filling volume can be accurately controlled. Therefore, the present invention also provides an adjustment assembly 230, which specifically includes an adjustment plate 231, a movable block 232, a side mounting plate 234 and a mounting plate 235. The specific structure is as follows: Figures 7-10 As shown in , a slide groove is provided on the adjustment block, and the movable block 232 can slide relatively in the slide groove, so that the position of the movable block 232 is adjustable, and one end of the movable block 232 is connected to the tail of the third cylinder 221, so that the installation point position of the third cylinder 221 can be relatively adjusted, thereby solving the technical problem of fixed installation of the existing rotating component 220, and further achieving precise adjustment and control of filling volume delivery.

[0054] In addition to the above-mentioned method of directly adjusting the installation position by using the movable block 232, an adjusting bolt can also be set on the side mounting plate 234. The adjusting bolt is connected to the other end of the movable block 232, so that the position of the movable block 232 can be fine-tuned. During use, the movable block 232 is first adjusted to float in the slide groove, and then the specific installation position is fine-tuned by the adjusting bolt, so as to achieve the purpose of better control.

[0055] In order to provide a stable installation environment for the adjustment plate 231 of the adjustment assembly 230, a mounting plate 235 is also provided. The mounting plate 235 is provided on a side wall of the adjustment plate 231 and connected to the valve body assembly 210, specifically connected to the connecting piece of the valve body assembly 210, as shown in the figure.

[0056] When the material goes down to the three-way valve core 211, the three-way valve core 211 is connected to the pushing device 300 through the rotating assembly 220, so that the material is sucked into the pushing device 300. The pushing device 300 includes a piston assembly 310, a connecting assembly 340 and a pushing assembly 320 in sequence. Fig.11 , 12 As shown in the figure, the piston assembly 310 mainly includes a piston cylinder 311 and a piston block 312, and the connecting assembly 340 mainly includes a connecting block connected to the piston block 312, and the end of the connecting block is connected to the pushing assembly 320 through a screw. Specifically, the pushing assembly 320 includes an electric push rod 321, and the power of the electric push rod 321 comes from the third drive motor 322.

[0057] Under the action of the third driving motor 322, the material is sucked into the piston cylinder 311. In order to achieve the purpose of accurately controlling the filling volume, the original cylinder propulsion method is changed to an electric push rod 321, which makes its accuracy relatively higher.

[0058] In addition, the existing position sensor 343 arranged on the cylinder is separately arranged at the position corresponding to the connecting component 340. The existing position sensor 343 is arranged on the cylinder, which easily ignores the connection gap between the cylinder and the piston rod, thereby causing a certain error in the measured position distance. The present invention specifically arranges a measuring block 342 on the connecting rod 341, and arranges a position sensor 343 outside it, so as to measure its position movement, and thus can more accurately monitor the filling material.

[0059] In the existing filling system, the piston assembly 310 and the pushing assembly 320 are directly installed on the support plate 424, while the pushing device 300 has relatively more parts and the installation positions are relatively close, so that once the existing pushing device 300 finds that the parts are damaged or need to be repaired, the installation and disassembly process is very time-consuming and labor-intensive. The present invention abandons the existing support plate 424 and adopts a single table plate 330. As shown in the figure, the piston assembly 310 and the pushing assembly 320 are integrated on the table plate 330, so that each pushing device 300 is a separate individual. When maintenance or modification is required, the table plate 330 is directly removed and replaced with a spare one, and then the parts on the replaced table plate 330 are repaired and processed, without delaying the filling process and without affecting the filling progress.

[0060] In the present invention, the piston assembly 310 and the platform 330 are fixedly connected via a first fixing plate 331 , and the pushing assembly 320 and the platform 330 are fixedly connected via a second fixing plate 332 .

[0061] After the filling material is sucked into the piston cylinder 311, the valve body assembly 210 is rotated by the rotating assembly 220 to connect the three-way valve core 211 with the canning device, specifically, with the filling head 411, and then the pushing assembly 320 is driven to push the filling device forward with the material.

[0062] The filling device mainly includes a filling head 411 and a lifting assembly 420. Figures 1 to 7 As shown in the figure, the lifting component 420 is used to drive the filling head 411 to rise and fall. The specific structure of the lifting component 420 includes a first drive motor 431, which transmits the power to the lifting column 421 through a belt 432. Specifically, a gear is set on the lifting column 421, and the belt 432 cooperates with the gear to make the lifting column 421 rise or fall.

[0063] A first lifting member 422 and a second lifting member are respectively arranged at the bottom of the lifting column 421. The first lifting member 422 and the second lifting member are connected via a connecting column 423, wherein the second lifting member is connected to a transverse plate 429, and the filling head 411 is connected to the transverse plate 429 via a slider 430. The slider 430 can slide on the transverse plate 429, so that the spacing between the filling heads 411 of the transverse plate 429 can be adjusted, so that it can meet the demand of not being able to fill in batches.

[0064] A support plate 424 and a vertical plate 425 are provided on the first lifting member 422, and a first cylinder 426 is provided on the vertical plate 425. A material receiving plate 427 is provided at the end of the first cylinder 426. The material receiving plate 427 is provided at the bottom of the filling head 411 to receive excess material on the filling head 411, thereby preventing the material on the filling head 411 from dripping onto the conveyor belt 441 below when the filling head 411 is lifted after a batch of filling bottles is filled, thereby avoiding contamination.

[0065] Also in order to make it more automated, a counting mechanism 440 is provided at the bottom of the filling head 411. As shown in the figure, the counting mechanism 440 mainly includes a conveyor belt 441, a counting sensor 442, a second cylinder 443 and a fourth drive motor 445. Driven by the fourth drive motor 445, the conveyor belt 441 is transported, and the filled bottles are placed on the conveyor belt 441. By providing the counting sensor 442, the filled bottles entering the bottom of the filling head 411 through the conveyor belt 441 can be counted to make their number consistent with the number of the filling head 411. When the consistency is reached, the baffle 444 is driven forward by the second cylinder 443 to block the subsequent transmission of the filled bottles.

[0066] After the filling bottle reaches the filling head 411, the lifting assembly 420 extends the filling head 411 downward into the filling bottle for filling. After the filling is completed, the lifting assembly 420 lifts the filling head 411 upward and away from the filling bottle to complete the filling.

[0067] The present invention also provides a specific filling method, and the specific steps are as follows:

[0068] S1: Materials are placed in the material tank 100, and the agitator 110 in the tank stirs the materials to mix them evenly, and then the materials are discharged to the regulating device 200;

[0069] S2: The material is placed in the three-way valve core 211. Under the action of the rotating assembly 220, the three-way valve core 211 makes the piston assembly 310 of the pushing device 300 communicate with the three-way valve core 211. Under the action of the pushing assembly 320, the material is sucked into the piston assembly 310.

[0070] S3: The three-way valve core 211 is connected to the filling head 411 by rotating the component 220, and the material is pushed into the filling head under the action of the pushing component 320;

[0071] S4: The filling bottles move on the conveyor belt 441 to move toward the bottom of the filling head 411. The number of filling bottles is accurately controlled by the counting sensor 442, and the baffle 444 blocks the subsequent filling bottles by driving the second cylinder 443;

[0072] S5: When the filling bottle reaches the bottom of the filling head 411 accurately, the first driving motor 431 drives the lifting assembly 420 to move downward, so that the filling head 411 extends into the filling bottle for filling. After the filling is completed, the first driving motor 431 drives the lifting assembly 420 to move upward, so that the filling head 411 extends out of the filling bottle.

[0073] S6, by driving the first cylinder 426, the material receiving plate 427 extends to the bottom of the filling head 411 to receive the material at the bottom of the filling head 411.

[0074] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
