[0020] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0022] Such asFigures 1-4 As shown in the figure, the utility model is a cyanuric chloride packaging scale, which includes a steel platform 12 and a hook 8. A weighing sensor 6 and a bin 4 are arranged on the steel platform 12. A spiral motor 1 and a stirring motor 2 are installed at the upper end of the bin 4; a straight pipe 7 is installed at the lower end of the bin 4, and the straight pipe 7 is of a sealed structure to further reduce the amount of dust overflow.

[0023] A first vacuum pump 10 and a second vacuum pump 11 are installed on the straight pipe 7; at least two lifting devices 5 are also arranged on the steel platform 12; the hook 8 is connected to the lifting device 5, and a bag clamping device 9 is arranged between the hooks 8, and the bag clamping device 9 is connected to the straight pipe 7.

[0024] Through the design of the straight pipe 7, the first vacuum pump 10 and the second vacuum pump 11 perform vacuum negative pressure treatment on the material, and suck the toxic dust and gas generated during the packaging process to the external dust removal equipment, so as to reduce the risk of poisoning of workers caused by the volatilization of cyanuric chloride material during the packaging process.

[0025] A spiral auger is arranged inside the straight pipe 7. The upper end of the spiral auger is the spiral auger feed inlet, and the lower end is the spiral auger discharge outlet; and a cut-off door is arranged at the spiral auger discharge outlet to reduce the risk of material leakage and improve the packaging accuracy.

[0026] The straight pipe 7 is designed with a sandwich structure, and the inner layer is a microporous pipe; while adding materials, the first vacuum pump 10 generates negative pressure to suck the air inside the straight pipe 7, making the material density compact.

[0027] A weighing module is arranged on the steel platform 12, and the weighing sensor 6 is located on the weighing module to reduce the corrosion of the weighing sensor 6 by the material.

[0028] A glass observation port is arranged on the bin 4 to facilitate observing the state of the material during the packaging process; a rotary vane level gauge 3 is also arranged on the bin 4, which can timely feedback the state of too little or too much material. An opening is arranged at the bottom of the bin 4 to facilitate the maintenance and cleaning of the bin 4.

[0029] The bag clamping device 9 is an airbag bag clamping device, which makes the sealing performance better and more effectively reduces dust.

[0030] The lifting device 5 includes a cylinder and a chain. A cylinder is installed on the steel platform 12, and the output end of the cylinder is connected to the hook 8 through the chain.

[0031] Manually hang the packaging bag sling on the hook 8, and put the bag mouth into the bag clamping device 9. At this time, the airbag of the bag clamping device is inflated, and the bag clamping device 9 tightly holds the bag mouth of the packaging bag to seal the bag mouth of the packaging bag.

[0032] Next, the lifting device 5 lifts the packaging bag to a high position. As the materials in the packaging bag rise, the lifting device 5 slowly descends. At this time, the cutting gate opens, the stirring motor 2 is powered on and operates, and the screw motor 1 runs at a high frequency, causing cyanuric chloride materials to fall into the lower packaging bag. The first vacuum pump 10 is started to degas the materials in the straight pipe 7.

[0033] When the weighing sensor 6 detects that the cyanuric chloride materials in the packaging bag reach the initially set weight and sends a signal, the screw motor 1 changes to low-frequency operation for slow feeding, and the first vacuum pump 10 stops working.

[0034] When the weighing sensor 6 detects that the cyanuric chloride materials in the packaging bag reach the set final weight, the screw motor 1 stops rotating, the stirring motor 2 also stops operating at the same time, the cutting gate closes, the entrainer 9 opens, the hook 8 disengages from the packaging bag, and the packaging bag drops.

[0035] During this process, when the screw motor 1 is working, the second vacuum pump 11 evacuates the internal cavity of the entrainer 9 at the material falling position to extract the dust generated in the internal cavity and the packaging bag.

[0036] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
