Description

Technical Field

[0001] This utility model belongs to the field of food additive packaging technology, and relates to a weighing and quantitative packaging machine for food additives. Background Technology

[0002] When packaging food additives, it is necessary to add a fixed amount of material into the packaging bag. Existing methods of quantitative feeding are to achieve equal feeding by intermittently controlling the opening and closing of the feeding mechanism. However, this method has low precision, cannot guarantee that the amount of material added each time is equal, and can only meet the feeding requirements of one weight of food additive.

[0003] A Chinese utility model patent with publication number CN214824312U discloses a quantitative packaging machine for food additives, comprising a mounting frame, a feeding funnel, and a quantitative block coaxial with the feeding funnel. The machine is characterized by having a cover plate movable to cover the discharge port of the feeding funnel and a first driving mechanism for moving the cover plate. A discharge funnel located at the bottom of the feeding funnel is also present on the mounting frame. The quantitative block is rotatably mounted inside the discharge funnel. The quantitative block has a groove facing the feeding funnel and a weighing sensor. A power assembly for driving the quantitative block to rotate vertically is also present on the mounting frame. The weighing sensor is signal-connected to the first driving mechanism and the power assembly.

[0004] The existing technology has the following technical defects:

[0005] The above technical solution can only weigh and package once. After weighing, the material is unloaded and packaged, but it cannot be weighed again. This results in a long waiting time for the next packaging, and its weighing and packaging efficiency is low. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a weighing and quantitative packaging machine for food additives.

[0007] The present invention relates to a weighing and quantitative packaging machine for food additives, comprising a frame, wherein the frame is provided with a feeding hopper, a distributing hopper, a packaging hopper, and a control box from top to bottom. The control box contains a control system. The feeding hopper has a feeding port at its bottom, and a corresponding feeding baffle is movably connected to the feeding port. The feeding baffle is connected to a feeding cylinder fixed to the frame via a connecting plate. The distributing hopper corresponding to the feeding port is fixedly connected to the frame via a connecting frame. Guide rails are fixedly connected to both sides of the discharge port at the bottom of the distributing hopper, and a discharge baffle is slidably connected to the guide rails. A discharge cylinder is connected to the discharge baffle and fixed to the connecting frame. A plate weight sensor is provided on the discharge baffle. The packaging hopper is located below the discharge port of the distributing hopper, and a packaging bag support assembly is provided at the bottom of the packaging hopper. The feeding cylinder, the discharge cylinder, the plate weight sensor, and the packaging bag support assembly are all connected to the control system.

[0008] The packaging bag support assembly includes a loading adjustment plate symmetrically hinged to the frame and a support plate fixed to the frame. Both support plates have a bag support plate hinged to their bottoms. The same adjusting cylinder is hinged to both loading adjustment plates. The two loading adjustment plates are movably connected to the bag support plates. The adjusting cylinder is connected to the control system. By adjusting the cylinder, the two loading adjustment plates can be moved inward or outward synchronously, thereby adjusting the opening and closing degree of the support outlet according to the size of the packaging bag. When the loading adjustment plate moves, the bag support plate that is in contact with it also rotates, thereby adjusting the support force.

[0009] The bag support plate is L-shaped and equipped with magnets that are compatible with the filling adjustment plate. The L-shaped bag support plate can more forcefully open the bag opening and prevent the bag from falling off due to the impact and gravity of the material falling. At the same time, the magnets are used to attach and fix the bag support plate and the filling adjustment plate together, which can not only achieve the attachment of the two, but also allow the two to be adjusted in position during movement without interference.

[0010] The feeding hopper is equipped with a dispensing peak and has at least two feeding ports. Each feeding port is equipped with a feeding cylinder and a dispensing hopper. The bottom of the two dispensing hoppers corresponds to the same packaging hopper. After one dispensing hopper has finished weighing, the material is discharged for packaging. The other dispensing hopper can be prepared for weighing. After packaging, the other dispensing hopper is used for packaging. After the previously discharged dispensing hopper is closed, the material is weighed again, thereby improving the efficiency of packaging and weighing.

[0011] The hopper is equipped with an observation window to facilitate observation of the material inside the hopper.

[0012] The hopper is equipped with a level gauge, which allows the system to monitor the material level inside the hopper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses multiple hoppers for step-by-step weighing and packaging. Compared to existing weighing and packaging methods that require packaging to be completed before re-weighing, which affects work efficiency, this device can use multiple hoppers for alternating weighing and packaging, resulting in higher packaging efficiency.

[0021] Example 1

[0022] like Figures 1-5As shown, the weighing and quantitative packaging machine for food additives of this utility model includes a frame 4. From top to bottom, the frame 4 is provided with a feeding hopper 1, a distributing hopper 6, a packaging hopper 9, and a control box 10. The control box 10 contains a control system. The bottom of the feeding hopper 1 has a feeding port 16, and a corresponding feeding baffle is movably connected to the feeding port 16. The feeding baffle is connected to a feeding cylinder 19 fixed to the frame 4 via a connecting plate 18. The frame 4 is fixedly connected to the distributing hopper 6 corresponding to the feeding port 16 via a connecting frame 5. Guide rails 8 are fixedly connected to both sides of the bottom discharge port of the distributing hopper 6. A discharge baffle 20 is slidably connected to the guide rails 8. A discharge cylinder 7 is fixed to the discharge baffle 20 on the connecting frame 5. The discharge baffle 20 has a plate... The plate-type weight sensor can be a TK307 ultra-thin plate-type weighing and force sensor. A flat protective device adapted to the plate-type weight sensor is installed on the discharge baffle 20 to prevent material from entering and causing jamming. The packaging hopper 9 is located below the discharge port of the distributing hopper 6. A packaging bag support assembly is provided at the bottom of the packaging hopper 9. The feeding cylinder 19, the discharge cylinder 7, the plate-type weight sensor, and the packaging bag support assembly are all connected to the control system. The packaging bag support assembly includes a loading adjustment plate 13 symmetrically hinged to the frame 4 and a support plate 11 fixed to the frame 4. A bag support plate 12 is hinged to the bottom of each support plate 11. The same adjustment cylinder 14 is hinged to each of the two loading adjustment plates 13. The two loading adjustment plates 13 and the bag support plate 12... The movable connection connects the adjusting cylinder 14 to the control system. The movement of the adjusting cylinder 14 synchronously drives the two filling adjusting plates 13 to move inward or outward, thereby adjusting the opening and closing degree of the support outlet according to the size of the packaging bag. When the filling adjusting plate 13 moves, the bag-supporting plate 12, which is attached to it, also rotates, thus adjusting the support force. The bag-supporting plate 12 is L-shaped and equipped with magnets 17 that match the filling adjusting plate 13. The L-shaped bag-supporting plate 12 can more forcefully open the packaging bag opening, preventing the packaging bag from falling off due to the impact and gravity of falling materials. Simultaneously, the magnets 17 are used to attach and fix the bag-supporting plate 12 and the filling adjusting plate 13, achieving both adhesion and... The two components can be adjusted in position during movement without interference. The hopper 1 is equipped with a dispensing peak 15 and at least two discharge ports 16. Each discharge port 16 is equipped with a discharge cylinder 19 and a dispensing hopper 6. The bottoms of the two dispensing hoppers 6 correspond to the same packaging hopper 9. After one dispensing hopper 6 has finished weighing, the material is discharged for packaging. The other dispensing hopper 6 can be prepared for weighing. After packaging, the other dispensing hopper 6 is used for packaging. The previously discharged dispensing hopper 6 is closed and weighed again, thereby improving the efficiency of packaging and weighing. The hopper 1 is equipped with an observation window 3 for easy observation of the material in the hopper 1. The hopper 1 is equipped with a level gauge 2, which can monitor the material in the hopper 1 through the system.

[0023] Working process or working principle:

[0024] In use, material is injected into the feeding hopper 1. The control system controls the opening and closing of two feeding cylinders 19. When the material enters the plate-type weight sensor in its corresponding distributing hopper 6 through the feeding port 16, the weight on the sensor is fed back to the control system. When the weight reaches the required level, the corresponding feeding cylinder 19 is closed. Because the distributing hopper 6 has a certain height, the weight sensor will have a certain delay during the material's descent. This issue can be addressed by manually adjusting the sensor based on the actual shape and size of the additives in the application scenario, thereby achieving the desired result. To achieve the required accuracy, when the feeding cylinder 19 corresponding to the feedback information from the weight sensor closes the feeding port 16, the appropriate discharging cylinder 7 corresponding to the appropriate discharging hopper 6 is activated, driving the discharging baffle 20 to move so that the accumulated material falls into the packaging funnel for packaging. After packaging is completed, the discharging baffle 20 is reset, and the feeding cylinder 19 is reopened to re-weigh. At this time, another discharging hopper 6 can be opened to pack the material that has already been weighed. After packing is completed, the first discharging hopper 6 is also re-weighed and can be packed. This process is repeated to improve the weighing and packing efficiency.

[0025] This invention uses multiple hoppers 6 for step-by-step weighing and packaging. Compared with existing weighing and packaging methods that require packaging to be completed before re-weighing can be performed after each weighing, which affects work efficiency, this device can use multiple hoppers 6 for alternating weighing and packaging, resulting in higher packaging efficiency.

[0026] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
