Description

Technical Field

[0001] The present invention relates to the technical field of sauce packaging, and particularly relates to a multi-pipeline filling sauce packaging machine. Background Art

[0002] With the increasing expansion of the application field of fully automatic packaging machines, the types of packaging materials are also becoming increasingly diverse. A considerable number of market customers need to automatically package liquid sauces. A liquid sauce packaging machine is used for filling viscous sauces with a certain fluidity. During the production process of sauces, after the production raw materials are steamed in a sauce cooking machine, they are discharged into a cooling tank and then sent to a sauce packaging machine for packaging.

[0003] Existing packaging machines fill sauces with a single pipeline. Since the sauce contains particulate solids, thick substances, and liquids, during the filling process, metering is carried out by a metering pump. Due to the relatively large fluidity of liquids and solids, the accuracy of the total amount of filled sauce is relatively high. However, for example, there is often a certain error in the solid-liquid ratio, which will reduce the taste of the sauce; and filling sauces with a single pipeline will also limit the production process, and the evaluation of taste levels is relatively single.

Detailed Implementation Modes

[0031] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] As Figures 1-12 shown, a multi-pipeline filling sauce packaging machine. In the present invention, the whole machine part of the packaging machine adopts an existing structure, so the packaging structure of the packaging machine will not be elaborated too much in this embodiment; in the present invention, the packaging machine is provided with a feeding mechanism for conveying different materials in multiple pipelines, and the output end of the feeding mechanism injects multiple materials into the same packaging bag 0 on the packaging machine; each feeding mechanism has components such as a storage barrel, a filling pump, and a feeding pipe. The input end of the filling pump is communicated with the storage barrel, and the feeding pipe is connected to the output end of the filling pump. The filling pump is a Haiba pump, which can accurately control the injection amount of the material. After the present invention is provided with a multi-pipeline feeding mechanism, it can be filled with one type of material bag by using one pipeline for filling alone, such as vinegar bags, oil bags, etc., or it can be filled with multiple different materials, such as a mixed material composed of alcohol, oil, sauce, etc., and each material is controlled for filling separately. The control accuracy of the injection amount of the material is high, and the accuracy of the solid-liquid ratio is high, improving the taste of the sauce.

[0033] In the application of multi-pipeline filling, due to the volume limitation of the packaging bag 0, when filling with three or more pipelines, often the multi-pipeline feeding pipes cannot be inserted into the packaging bag 0 at the same time. Therefore, in this embodiment, a feeding mechanism is connected to the output end of the feeding mechanism, and the number of pipes inserted into the packaging bag 0 is adjusted through the feeding mechanism. When filling with multiple pipelines, a certain number of pipes can be alternately inserted into the packaging bag 0, thereby realizing multi-pipeline material filling.

[0034] Therefore, specifically, as Figures 1-4As shown, the filling mechanism includes an L-shaped mounting plate 1. The horizontal section of the mounting plate 1 is bolted to the machine table of the packaging machine. A guiding barrel 2 is provided on the mounting plate 1. The top of the guiding barrel 2 has a board which is detachably connected to the vertical section of the mounting plate 1 by bolts. The lower part of the guiding barrel 2 is in a frustum shape. The small end of the guiding barrel 2 is at the bottom, that is, the outer diameter of the lower end of the guiding barrel 2 is relatively small, and the lower end of the guiding barrel 2 can be directly placed above the packaging bag 0. A number of filling pipes 3 are provided in the guiding barrel 2. The output end of each feeding mechanism is communicated with the filling pipe 3. Since the upper part of the guiding barrel 2 has a large diameter and the lower part has a small diameter, it is convenient to store multiple filling pipes 3 in the upper part of the guiding barrel 2. The small structure of the lower part plays a guiding role for the filling pipe 3 when the filling pipe 3 moves downward, making the filling pipe 3 shift towards the middle and facilitating it to pass through the lower end of the guiding barrel 2. At the same time, a driving component for controlling the filling pipes 3 to alternately extend out of the bottom of the guiding barrel 2 is also provided on the mounting plate 1. Therefore, when it is necessary to inject a kind of material, the driving component drives the filling pipe 3 to move downward and pass through the outside of the guiding barrel 2. At this time, the material is filled into the packaging bag 0. When filling multiple materials, after one kind of material is filled, the driving component drives this filling pipe 3 to reset; at the same time, it drives the next filling pipe 3 to move downward for filling operation, and the cycle is repeated to continuously package the sauce. Therefore, in this embodiment, the driving component can be multiple electric telescopic rods, and each electric telescopic rod controls the filling pipe 3 independently, so as to realize the lifting control of the filling pipe 3. Since the filling pipe 3 will shift towards the middle of the guiding barrel 2 during the downward movement, a rubber pipe 7 is provided at the lower part of the filling pipe 3. The rubber pipe 7 has a certain elastic deformation ability to adapt to the offset that occurs when the filling pipe 3 moves downward.

[0035] Further, the method of driving each of the above-mentioned material injection pipes 3 by an electric telescopic rod is applicable to the scenario with a small number of three material injection pipes 3; when the number of material injection pipes 3 is larger, the filling efficiency of the material will be greatly reduced. In order to improve the filling efficiency of multiple materials; therefore, three cavities 4 are partitioned in the lower frustum of the guiding barrel 2, and three outlets 5 communicating with the corresponding cavities 4 are provided on the small end face of the guiding barrel 2. The cavities 4 are structured with a larger upper part and a smaller lower part. Multiple material injection pipes 3 are placed in each cavity 4. In this embodiment, two or three material injection pipes 3 are arranged in each cavity 4. Therefore, when filling the material, it is possible to fill up to nine paths of materials at most. Usually, in actual applications, only two material injection pipes 3 need to be arranged in each cavity 4 to meet the filling requirements. A guiding block 6 is provided on the inner wall of the upper part of the guiding barrel 2, and the material injection pipe 3 is inserted through the guiding block 6. A rubber pipe 7 is provided at the lower part of the material injection pipe 3. The driving assembly can control the three material injection pipes 3 to simultaneously extend out of the outlet 5. Therefore, three different materials can be simultaneously filled each time during filling. By alternately controlling, it is possible to achieve filling of four, five or six materials. Filling six materials only requires two alternations, greatly improving the filling efficiency.

[0036] Further, when there are five or six materials, the same number of electric telescopic rods need to be set, and the control structure is relatively complex and the cost is relatively high; in order to simplify the control structure and reduce the operating cost, it is necessary to optimize the driving assembly, that is, the driving assembly includes multiple connecting plates 8. The number of the connecting plates 8 is the same as the number of the material injection pipes 3 in each cavity 4. Each connecting plate 8 is correspondingly connected to one material injection pipe 3 in each cavity 4. In this embodiment, the number of the connecting plates 8 is set according to the number of the material injection pipes 3. When two material injection pipes 3 are arranged in each cavity 4, two connecting plates 8 are used; when three material injection pipes 3 are arranged in each cavity 4, three connecting plates 8 are used; the layout of the connecting plates 8 is as Figure 6 shown. In actual applications, during the lifting process of each connecting plate 8, there will be no mutual influence, which is convenient for controlling the alternate continuous injection of the material injection pipes 3 and improving the filling efficiency; the top of the material injection pipe 3 is inserted through the connecting plate 8. In this embodiment, the top of the material injection pipe 3 has a threaded end, and the connecting plate 8 has a threaded hole 23. The material injection pipe 3 is threadedly connected to the threaded hole 23 on the connecting plate 8; the driving assembly further includes a mounting frame 9 provided above the guiding barrel 2. The mounting frame 9 is fixed on the top of the mounting plate 1. The mounting frame 9 is provided with push rods 10 having the same number as the connecting plates 8, that is, electric telescopic rods are used. The telescopic end of the push rod 10 is connected to the corresponding connecting plate 8. In this embodiment, two or three electric telescopic rods can be used to achieve this, reducing the control difficulty to a certain extent.

[0037] The electric telescopic rod drive method requires reciprocating control. During alternating filling, it is necessary to ensure that the filled injection tube 3 is in the upward stroke before the injection tube 3 to be filled can move downward, otherwise the injection tube 3 will be damaged. Therefore, it is necessary to set a travel switch in the guide barrel 2 to detect the position of the injection tube 3. After reaching the corresponding stroke, the subsequent material filling can be started; therefore, the control method needs to be optimized.

[0038] Furthermore, the push rod 10 adopts a pneumatic push rod 10, which is composed of a cylinder body, a piston and a piston rod. The pneumatic push rod 10 is retracted and extended by air pressure. The driving assembly also includes an air supply structure for providing air pressure to the push rod 10. A return spring 11 is sleeved on the injection tube 3 in the guide barrel 2. When the return spring 11 is in a natural state, the injection tube 3 is located in the upper space of the guide barrel 2. After the pneumatic push rod 10 is injected with air, the piston rod moves downward, pushing the injection tube 3 to move downward. At this time, the return spring 11 is compressed. When alternate filling is required, the filled pneumatic push rod 10 is disconnected from the air source, and the injection is started. The material tube 3 moves upward under the action of the reset spring 11, and at the same time, the pneumatic push rod 10 to be filled is started, driving the corresponding injection tube 3 to move downward; the control method is further simplified. At the same time, after the pneumatic push rod 10 is disconnected from the air source, there is still air pressure in the cylinder body, and there is an exhaust process. Therefore, the reset process of the injection tube 3 is relatively smooth, and the initial reset acceleration will not be too large due to the elastic force of the reset spring 11, causing the material in the injection tube 3 to spill out, resulting in material waste; at the same time, it can also prevent the spilled material from falling on the seal of the packaging bag 0, causing material clamping, and reducing the packaging yield.

[0039] Furthermore, in order to ensure the alternating inflation of two or three pneumatic push rods 10, the air supply structure includes an air pump and an air supply switching disk connected to the air pump, and the air supply switching disk has the same number of air outlets 17 as the push rods 10, and the air outlets 17 are connected to the air inlet ends of the corresponding push rods 10.

[0040] Specifically, Figures 7-11As shown in the figure, the air supply switching disc includes a disc base 12 and a disc cover 13 rotatably connected to the disc base 12. An air delivery channel 14 is provided on the disc cover 13. A first groove 15 is provided on the inner side wall of the disc cover 13. One end of the air delivery channel 14 communicates with the first groove 15, and the other end of the air delivery channel 14 penetrates through the middle outer wall of the disc cover 13. A plurality of second grooves 16 are provided on the inner surface of the disc base 12. The number of the second grooves 16 is the same as that of the push rods 10, which is set to two or three, and the second grooves 16 are equally spaced in the circumferential direction on the disc base 12. Each of the second grooves 16 has an air outlet 17, and a sealing ring 18 is provided on the side wall of the disc base 12 around the second groove 16. Therefore, when the disc cover 13 rotates, when the positions of the first groove 15 and the second groove 16 are opposite, the push rod 10 connected to the second groove 16 by the air pump is connected, and the push rod 10 is inflated. The structure of the sealing ring 18 is as Figure 8 shown. The sealing ring 18 has an inner ring and an outer ring, and side rings provided at both ends of the second groove 16. Therefore, at any position when the disc cover 13 rotates, the air passage composed of the first groove 15, the second groove 16, and the air delivery channel 14 is in a sealed state;

[0041] The air supply switching disc further includes a bracket 19 for fixing the disc base 12. A motor 20 for driving the disc cover 13 to rotate is provided on the bracket 19. A toothed ring 24 is provided on the disc cover 13, and a gear 25 is provided at the driving end of the motor 20. The gear 25 meshes with the toothed ring 24. In this embodiment, when filling 1 - 3 kinds of materials, the motor 20 is started to make the first groove 15 opposite to one of the second grooves 16, and the feeding pipe is connected to the corresponding injection pipe 3. When filling more than 3 kinds of materials, the motor 20 needs to be started to drive the disc cover 13 to rotate. The length of the first groove 15 can be set. When the first groove 15 completely leaves the sealing position of the previous second groove 16, the first groove 15 just enters the range of the next second groove 16 to continue inflating the next push rod 10. Since the previous push rod 10 needs to deflate, a plurality of exhaust holes 22 are provided on the disc cover 13. The position relationship of the exhaust holes 22 is as Figures 7-8 shown, which can ensure that the inflation and deflation processes alternate during the rotation of the disc cover 13.

[0042] Further, the other end of the air delivery channel 14 is connected with a rotary joint 21. As Figure 11 shown, the air delivery channel 14 communicates with the air inlet pipe of the push rod 10 through the rotary joint 21, and the rotary joint 21 can adapt to the relative rotation between the rotary disc and the air pipe of the push rod 10.

[0043] Furthermore, due to the insufficient elasticity of the rubber tube 7 itself, the lifting of the injection tube 3 may cause the injection tube 3 to fail to pass through the outlet 5 because the rubber tube 7 has not restored its deformation. Therefore, an elastic rod 26 is provided on one side of the injection tube 3, as Figure 5 shown. The elastic rod 26 is made of materials such as steel wire and PCV and has good elasticity. Both ends of the rubber tube 7 are a section of hard tube, and both ends of the elastic rod 26 are fixedly connected to the hard tube. A connecting sleeve 27 is provided on the rubber tube 7, and the elastic rod 26 is inserted through the connecting sleeve 27 to ensure that the rubber tube 7 can restore its deformation after the injection tube 3 is reset.

[0044] Furthermore, a U-shaped rod 28 is provided on one side of the mounting plate 1. The U-shaped rod 28 is horizontally arranged and both ends are connected to the vertical section of the mounting plate 1. The U-shaped rod 28 is used to guide the packaging paper tape, as Figure 12 shown. Under the guiding action of the U-shaped rod 28, the packaging paper bag is folded in half to form the packaging bag 0.

[0045] It should be noted that for the foregoing method embodiments, for the sake of simple description, they are all expressed as a series of action combinations. However, those skilled in the art should know that this application is not limited by the described action sequence, because according to this application, some steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and units involved are not necessarily essential to this application.
