Description

Technical Field

[0001] This utility model relates to the technical field of combination scales, and in particular to a novel high-speed combination scale. Background Technology

[0002] Traditional multi-head combination scales temporarily store a certain amount of material in the storage hopper before feeding it into the weighing hopper for weighing (e.g., a high-speed combination scale disclosed in Chinese patent CN213481511U). The material is fed after the weighing hoppers are combined and selected, completing one combination. In this way, if there are 10 weighing hoppers, the maximum number of weights that can be combined is 10. If we want to increase the combination probability and improve the weighing accuracy, we need to increase the number of storage hoppers and weighing hoppers, which will make the equipment larger and the manufacturing cost higher. Therefore, how to design a new type of high-speed combination scale that can increase the combination probability without changing the number of weighing hoppers has become an urgent technical problem to be solved. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a new type of high-speed combination scale to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a novel high-speed combined scale is designed, comprising: a frame and a control device. A feeding hopper is fixedly connected to the top of the frame, a main vibrating plate is arranged below the feeding hopper, and multiple linear vibrating plates are distributed around the main vibrating plate. A weighing hopper for receiving its output material is provided below the discharge end of each linear vibrating plate, and a storage hopper for receiving its output material is arranged below each weighing hopper. A receiving hopper for receiving the output material from multiple storage hoppers is arranged at the lower part of the frame. A discharge port is provided at the bottom of the receiving hopper. A weighing sensor is arranged inside the weighing hopper. The weighing sensor, a drive device for controlling the feeding of the weighing hopper, and a drive device for controlling the feeding of the storage hopper are electrically connected to the control device. The control device is used to control several storage hoppers to simultaneously feed material according to a set weighing command, or to control several storage hoppers and one or more weighing hoppers above them to simultaneously feed material.

[0006] By employing the above technical solution, the positions of the weighing hopper and the storage hopper are interchanged. When the weighing sensor in the weighing hopper weighs the material, it feeds the weight information back to the control device. The control device then controls the weighing hopper to discharge the material into the storage hopper. When the vibrating disc discharges the material into the weighing hopper, the weighing sensor in the weighing hopper weighs the material and feeds the weight information back to the control device. At this time, the control device records the weight information of the material in multiple storage hoppers and multiple weighing hoppers. With the same number of weighing hoppers, the number of combined weights is doubled, increasing the combination probability, improving the combination speed and weighing accuracy. In addition, compared with the solution of increasing the number of weighing hoppers and storage hoppers, it can reduce manufacturing costs.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, a guide is inclinedly disposed below the hopper to receive the output material, the lower end of the guide extending into the receiving hopper.

[0009] In some embodiments, the guide member has a U-shaped structure.

[0010] In some embodiments, ten weighing hoppers are distributed circumferentially.

[0011] In some embodiments, the weighing hopper has fourteen circumferentially distributed.

[0012] In some embodiments, the weighing hopper and the storage hopper are respectively connected to the frame.

[0013] In some embodiments, the weighing hopper and the storage hopper are respectively fixed to the frame by screws. Attached Figure Description

[0021] refer to Figures 1 to 2 As shown, this utility model provides a novel high-speed combined scale, comprising: a frame 1 and a control device. A feeding hopper 2 is fixedly connected to the top of the frame 1. A main vibrating plate 3, fixedly connected to the frame 1, is arranged below the feeding hopper 2. Multiple linear vibrating plates 4 are distributed around the main vibrating plate 3. A weighing hopper 5 for receiving the output material is provided below the discharge end of each linear vibrating plate 4. That is, multiple weighing hoppers 5 are also arranged circumferentially. Specifically, three, four, five, six, seven, eight, ten, fourteen, or more weighing hoppers 5 are arranged circumferentially. In this embodiment, fourteen weighing hoppers 5 are evenly arranged circumferentially. Each weighing hopper 5 is equipped with a weighing sensor for weighing materials. Below each weighing hopper 5 is a storage hopper 6 for receiving the output material. Below each storage hopper 6 is a guide 7 for receiving the output material. The lower end of each guide 7 extends into the receiving hopper 8 located at the lower part of the frame 1. The receiving hopper 8 is funnel-shaped, and the guide 7 has a U-shaped structure. The guide 7 is used to receive the material output from the storage hopper 6 and discharge the material into the receiving hopper 8. The bottom of the receiving hopper 8 is provided with a discharge port, and the material entering the receiving hopper 8 can be discharged from the discharge port at the bottom of the receiving hopper 8.

[0022] Weighing hopper 5 is a conventional weighing hopper, such as the independent double-door dispensing hopper disclosed in patent CN208882551U, the self-balancing buffer hopper disclosed in patent CN208882557U, or the weighing hopper described in patent CN213481511U. Storage hopper 6 is a conventional storage hopper, such as the storage hopper described in patent CN213481511U, or a storage hopper of other structures.

[0023] The weighing hopper 5 is fixed to the frame 1 by screws, or the weighing hopper 5 is hung on the frame 1 by a hanging groove provided on it. In this embodiment, the weighing hopper 5 is preferably hung on the frame 1. When the weighing hopper 5 is discharging material, the control device controls the drive device on the weighing hopper 5 to start and drive the gate below it to open for discharging. After discharging is completed, the gate closes.

[0024] The storage hopper 6 is fixed to the frame 1 by screws, or the storage hopper 6 is hung on the frame 1 by a hanging groove provided on it. In this embodiment, the storage hopper 6 is preferably hung on the frame 1. When the storage hopper 6 discharges material, the control device controls the drive device on the storage hopper 6 to start and drive the gate below it to open for material discharge. After the material discharge is completed, the gate closes.

[0025] The weighing sensor, the drive device for controlling the discharge of material from the weighing hopper 5, and the drive device for controlling the discharge of material from the storage hopper 6 are electrically connected to the control device. The control device is an automation control unit / device, such as a control circuit board, PLC controller, or industrial computer, used to control the start and stop actions of each drive component. The control device is used to control several storage hoppers 6 to discharge material simultaneously, or to control several storage hoppers 6 and the weighing hopper 5 above or above one of those storage hoppers 6 to discharge material simultaneously, according to the set weighing instructions.

[0026] The weighing principle of this novel high-speed combined scale is as follows: Material is manually or via a feeding machine conveyed into the feeding hopper 2 and falls onto the main vibrating plate 3. The main vibrating plate 3 vibrates, dispersing the material into multiple linear vibrating plates 4. These plates then convey the material into multiple weighing hoppers 5. After a set time, the main vibrating plate 3 and linear vibrating plates 4 stop. Weighing sensors in each of the weighing hoppers 5 feed back the weighed weight information to the control device. The control device then activates the drive mechanisms on each of the weighing hoppers 5, opening the gates below to allow material to flow into the storage hopper 6. After discharging, the gates close. Simultaneously, the control device records the weight of the material falling into each storage hopper 6. The control device then restarts the main vibrating plate 3 and linear vibrating plates 4, allowing material to flow into the weighing hoppers 5 again. After a set time, the main vibrating plate 3 and linear vibrating plates 4 stop, and the weighing sensors feed back the weighed weight information. The control device records the weight of materials in multiple storage hoppers 6 and multiple weighing hoppers 5. When the combined scale needs to discharge materials of a set weight, if the sum of the weights of materials in several storage hoppers 6 equals the set weight, the control device controls the simultaneous discharge of materials from the several storage hoppers 6 according to the set weighing command. If the sum of the weights of materials in several storage hoppers 6 and the weights of materials in the weighing hoppers 5 above one or several storage hoppers 6 equals the set weight, the control device controls the simultaneous discharge of materials from the several storage hoppers 6 and the weighing hoppers 5 above one or several storage hoppers 6. The materials output from the bottom of the storage hoppers 6 or from the weighing hoppers 5 and the bottom of the storage hoppers 6 enter the receiving hopper 8 through the guide 7 and are collected together, and then output from the discharge port at the bottom of the receiving hopper 8.

[0027] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
