Description

Technical Field

[0001] This invention relates to the field of plate chain weighing, and specifically to a multifunctional plate chain weighing device and its weighing method. Background Technology

[0002] Currently, most types of packaging conveyor belts use an on-top weighing method. The required weight of a bag is filled through a funnel-type hopper and then transferred to a ton bag. This weighing method places great demands on the space required for the equipment layout. Therefore, most packaging machines in China are semi-automatic and require manual bagging. The materials being bagged may pose health hazards to workers and increase their workload, especially in the chemical industry where materials containing dust and corrosive substances pose significant safety risks to workers.

[0003] Meanwhile, the aforementioned heavy packaging scale uses a four-corner manual bag hanging method, which requires two people to operate simultaneously. This not only results in high labor costs, but also requires multiple up-and-down shaking of the material during the loading process. The discharge port is closed during shaking, which slows down the loading speed. Furthermore, after loading, workers go to the loading port to remove the hanging bag, tie the bag opening tightly, and then it is conveyed out by the plate chain conveyor. This method involves a large workload for workers and poses safety hazards. Summary of the Invention

[0035] A weighing method for a multifunctional plate chain weighing device includes the following steps:

[0036] S1. When in use, the robot grabs an empty bag and places it in the feeding port, and inflates the empty bag to make it easier to feed.

[0037] S2. Then, the lifting motor starts, and the box beam moves through the first chain, the second chain, the upper sprocket device and the lower sprocket device, thereby driving the plate chain conveyor to rise to the bottom of the empty bag through the plate chain hanger and lift the empty bag.

[0038] S3. Subsequently, the rear baffle closes under the action of the rear baffle cylinder, pressing against and securing the empty bag.

[0039] S4. After that, the material begins to fall from the discharge port. The weight of the material is obtained through a fixed weighing sensor. The material is loaded until the required weight is reached, and then the discharge hopper door is closed.

[0040] S5. In addition, during the loading process, a vibration time point is set. When the predetermined weight is reached, the pneumatic vibrator starts to work to compact the material.

[0041] S6. After loading is completed, the plate chain drive motor starts, driving the plate chain conveyor to transport the material to the next workstation to continue the next process.

[0042] Beneficial effects: This invention relates to a multifunctional plate chain weighing device and its weighing method. By installing several pneumatic vibrators under the plate chain conveyor, the material can be made more compact through vibration, allowing the ton bags to quickly deform and thus hold more material, making them easier to stack during loading. Simultaneously, this application adopts a bottom weighing method, using a V-shaped plate chain hanger to support the plate chain conveyor, and then selecting fixed weighing sensors fixed to the box beam, thus combining weighing and conveying. Furthermore, by using a sprocket device in conjunction with a motor, box beam, and plate chain hanger to drive the plate chain conveyor up and down, this application can be compatible with various sizes of packaging ton bags, ensuring that the correct quantity of material is loaded each time.

Detailed Implementation

[0054] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0055] The applicant argues that most existing types of packaging conveyor belts use an on-top weighing method, which requires manual bagging. The materials being loaded may pose health hazards to workers and increase their workload. This is especially true in the chemical industry, where materials containing dust and corrosive substances pose significant safety risks to workers. Furthermore, the aforementioned heavy packaging scales also suffer from drawbacks such as high labor costs, slow loading speed, heavy workload for workers, and safety hazards.

[0056] Therefore, the applicant proposes a multifunctional plate chain weighing device and its weighing method, wherein the multifunctional plate chain weighing device, such as... Figures 1-10As shown, it includes a pair of frames 1, a pair of lower sprocket assemblies 14, a pair of motor housings 4, a pair of lifting motors 2, a pair of upper sprocket assemblies 3, a pair of first chains 17, a pair of box beams 9, a pair of second chains 18, a pair of plate chain hangers 10, a plate chain conveyor 11, a plate chain drive motor 12, several pneumatic vibrators 15, and several fixed weighing sensors 8.

[0057] Each pair of frames 1 is equipped with a lower sprocket device 14.

[0058] A pair of motor housings 4 are installed on a pair of frames 1. Each pair of motor housings 4 is equipped with a lifting motor 2 and an upper sprocket device 3. A first chain 17 connects the lifting motor 2 and the upper sprocket device 3. A box beam 9, installed in the frame 1, is provided between the upper sprocket device 3 and the lower sprocket device 14. A pair of second chains 18 connect the upper sprocket device 3, the box beam 9, and the lower sprocket device 14. The box beam 9 is driven to move by the lifting motor 2 through the upper sprocket device 3, the lower sprocket device 14, the first chain 17, and the second chain 18.

[0059] In this application, the lifting motor 2 preferably adopts a geared motor with model number R97DRN100L4BE5, and the first chain 17 and the second chain 18 preferably adopt a motor drive chain with model number DCE16A. The above models can be selected but are not unique.

[0060] When in use, starting the lifting motor 2 can drive the corresponding components on the upper sprocket device 3 to rotate via the first chain 17. The upper sprocket device 3 drives the corresponding components on the lower sprocket device 14 to rotate via the second chain 18. This causes one side of the second chain 18 to move relative to the box girder 9, while the end of the second chain 18 fixed to the box girder 9 can drive the box girder 9 to move up and down.

[0061] A pair of plate chain hangers 10 are correspondingly installed on a pair of box beams 9. A plate chain conveyor 11 is installed on the pair of plate chain hangers 10. One end of the plate chain conveyor 11 is connected to a plate chain drive motor 12 for driving the plate chain conveyor 11. Several pneumatic vibrators 15 for vibrating and compacting materials are connected to the lower end of the plate chain conveyor 11. Several fixed weighing sensors 8 for weighing materials are correspondingly connected between the pair of plate chain hangers 10 and the pair of box beams 9.

[0062] In this application, the plate chain hanger 10 is V-shaped, the plate chain drive motor 12 is preferably a geared motor of model KA57-TDRN90L4, and the plate chain drive motor 12 is provided with a motor cover for protection. The pneumatic oscillator 15 is preferably model GT30, and the fixed weighing sensor 8 is preferably model WLC0745. The above models can be selected but are not unique.

[0063] In use, the connection between the fixed weighing sensor 8, the plate chain hanger 10, and the box beam 9 allows the plate chain conveyor 11 to move up and down via the movement of the box beam 9, thus adapting to various sizes of ton bags and ensuring that each loading is quantitative. At the same time, the pneumatic vibrator 15 and the fixed weighing sensor 8 can make the material more compact through vibration, allowing the ton bags to quickly and plastically hold more material, and making it easier to stack them during loading. Furthermore, the V-shaped plate chain hanger 10 supports the plate chain conveyor 11, which is fixed to the box beam 9 with the fixed weighing sensor 8, thus combining weighing and conveying.

[0064] like Figures 5-8 As shown, the device also includes a motor cover 402, a second connecting groove 901, and multiple pairs of chain connectors 19.

[0065] The motor cover 402 is correspondingly through-cut into the frame 1 and the motor housing 4.

[0066] The second connecting groove 901 is opened through the box girder 9, and the second chain 18 is set through the motor cover 402 and the second connecting groove 901.

[0067] Multiple pairs of chain connectors 19 are correspondingly connected to the box girder 9 and connected to the end of the second chain 18, so that the box girder 9 can drive the plate chain conveyor 11 to move up and down between the upper sprocket device 3 and the lower sprocket device 14 via the second chain 18.

[0068] In this application, the upper sprocket device 3 is installed inside the motor housing 4, and the lower sprocket device 14 is installed inside the frame 1. The upper sprocket device 3 and the lower sprocket device 14 are connected by a pair of second chains 18 that pass through the motor cover 402 and the second connecting groove 901. In addition, the ends of the pair of second chains 18 are fixedly connected to the box beam 9 through chain connectors 19. When in use, the lifting motor 2 is started, and the box beam 9 and the pair of second chains 18 can be moved relative to each other through the first chain 17, thereby realizing the up and down movement of the box beam 9.

[0069] In addition, the chain connector 19 consists of a screw of preferred type SRCS-R80-5 and a nut of type SRCS-R80-3, used to fix the end of the second chain 18 to the box girder 9.

The two guide pulley seats 701 and the nylon guide wheel rings 703 are set facing the guide column 101. When the box girder 9 moves up and down, the nylon guide wheel rings 703 will adhere to the guide column 101 and roll along with it, thereby guiding and restricting the degree of freedom of the box girder 9 and ensuring the normal up and down movement of the box girder 9.

[0075] like Figures 6-7 As shown, the upper sprocket device 3 includes a drive shaft 301, a pair of power sprockets 303, a pair of bearing seats 302, and a pair of lifting sprockets 304.

[0090] A pair of first connecting slots 401 are hinged to a pair of motor housings 4 to cooperate with the motor housings 4 to protect the lifting motor 2 and the upper sprocket device 3.

[0091] like Figures 1-9 As shown, two side baffle components 6 are installed on a pair of plate chain hangers 10. The side baffle component 6 includes a side baffle mounting bracket 601, a side baffle 603, a side baffle telescopic bracket 602, and a first adjusting pin 604.

[0105] Furthermore, the rear guard 5 and side guard 6 not only support the unloading ton bags but also prevent the materials from tilting. Together with the fixed weighing sensor 8, plate chain hanger 10, and box beam 9, this device can achieve functions such as universal packaging of materials, compacting materials, and conveying ton bags. In addition, this application has been put into use, and its advantages in actual use have far exceeded expectations.
