Description

Technical Field

[0001] The present invention relates to the technical field of weighing devices, in particular to a novel automatic weighing device. Background Art

[0002] People use various scales to measure the weight of objects. Scales work by converting an object's weight into a readable value or signal through mechanical balance, electromagnetic force, or electronic sensors. Integrated weighing scales typically have a discharge valve built into the scale body. Powdered material is fed into the weighing hopper through the feed port, where it is weighed by the weighing module. The weighed material is then discharged through the discharge valve into a discharge pipe, where it is then transported to the next process. However, if the discharge valve's air pipe, which connects to the outside world, is connected to the scale, the scale's accuracy decreases. Summary of the Invention

[0003] The main purpose of the present invention is to provide a new automatic weighing device to solve the problems raised in the related art.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a new automatic weighing device is provided, comprising a protective shell and a rotating cylinder arranged on the outer wall of the protective shell, and also comprising a weighing mechanism arranged inside the protective shell. After the powder is added to the weighing mechanism and weighed by the weighing mechanism, the rotating cylinder drives the weighing mechanism to rotate and pours out the powder in the weighing mechanism.

[0005] Furthermore, the weighing mechanism includes a modular platform scale, and a connecting rod is fixedly provided on one side of the modular platform scale.

[0006] Furthermore, the outer end of the connecting rod is fixedly connected to the driving shaft of the rotary cylinder, and the connecting rod passes through the side wall of the protective shell and is rotatably connected to the side wall of the protective shell.

[0007] Furthermore, a connecting block is fixedly provided on the top of the modular platform scale.

[0008] Furthermore, a weighing bowl is fixedly provided on the top of the connecting block, and the opening of the weighing bowl faces upward.

[0009] Furthermore, a discharge port is provided at the bottom of the protective shell.

[0010] Furthermore, a top cover is provided on the top of the protective shell, and the protective shell and the top cover are fixedly connected by a clamp.

[0011] Furthermore, the top cover is provided with a through feeding port.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present invention ensures that the modular platform scale can weigh powder in a relatively stable environment by providing a protective shell and a top cover for shielding wind and electrical signal interference, thereby improving its weighing accuracy; a rotary cylinder drives the weighing bowl to tilt and pour out the powder, and a pneumatic discharge valve is installed on the modular platform scale. Since the discharge valve is provided, there is no need to connect the discharge air pipe, thereby avoiding the influence of the discharge air pipe on the modular platform scale and further improving its accuracy.

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] This embodiment provides a new automatic weighing device, such as Figure 1 As shown, it includes a protective shell 1 and a rotating cylinder 5 arranged on the outer wall of the protective shell 1, and also includes a weighing mechanism arranged inside the protective shell 1. After the powder is added to the weighing mechanism and weighed by the weighing mechanism, the rotating cylinder 5 drives the weighing mechanism to rotate and pours out the powder in the weighing mechanism.

[0021] like Figure 2 As shown, the weighing mechanism includes a modular platform scale 9 , and a connecting rod 10 is fixedly provided on one side of the modular platform scale 9 .

[0022] The modular platform scale 9 uses a shielded cable and is equipped with a 1-SPL / 300G-1 weighing module produced by HBM of Germany. The measuring range of the modular platform scale 9 is 0 to 300g, and the error is between ±0.02.

[0023] The outer end of the connecting rod 10 is fixedly connected to the driving shaft of the rotary cylinder 5 . The connecting rod 10 passes through the side wall of the protective shell 1 and is rotatably connected to the side wall of the protective shell 1 .

[0024] A connecting block 8 is fixedly provided on the top of the modular platform scale 9 .

[0025] A weighing bowl 7 is fixed on the top of the connecting block 8, and the opening of the weighing bowl 7 faces upward. The inside of the weighing bowl 7 is fully polished to effectively prevent the adhesion and accumulation of powder.

[0026] A discharge port 6 is provided at the bottom of the protective shell 1 .

[0027] A top cover 2 is provided on the top of the protective shell 1, and the protective shell 1 and the top cover 2 are fixedly connected by a clamp 3. The protective shell 1 and the top cover 2 are both made of stainless steel, which can not only block external wind and prevent wind from interfering with the modular platform scale 9, but also isolate external electrical signal interference to prevent interference with the modular platform scale 9, thereby improving its weighing accuracy.

[0028] This embodiment preferably uses a T-bolt clamp, a 316 stainless steel thickened steel strip, a sealing strip on the inside, and a nut passing through the slot at the end of the steel strip to lock it, thereby fixing the protective shell 1 and the top cover 2 together.

[0029] The top cover 2 is provided with a feeding port 4 extending therethrough.

[0030] A feeding barrel 14 is fixed to the side of the feeding port 4. A double-screw conveying dragon 11 rotates inside the feeding barrel 14. A feeding barrel mounting bracket 12 is fixed to the outer end of the feeding barrel 14. The feeding barrel mounting bracket 12 is installed on the ground through a bracket. A motor 13 for driving the double-screw conveying dragon 11 to rotate is fixed to the outer side of the feeding barrel mounting bracket 12. A storage barrel 15 is provided on the top of the feeding barrel 14. The bottom of the storage barrel 15 is connected to the feeding barrel 14, and the end of the feeding barrel 14 is connected to the feeding port 4. The powder in the storage barrel 15 falls into the feeding barrel 14. The motor 13 drives the double-screw conveying dragon 11 to rotate and delivers the powder along the feeding barrel 14 to the feeding port 4, and finally falls into the weighing bowl 7.

[0031] The single small screw of the double-screw conveyor Jiaolong 11 has a diameter of 23mm and a speed ratio of 1:43. The small screw rotates one circle and discharges 0.1g of material, accurately controlling the loading weight.

[0032] Feeding port 4 is connected to a double-screw conveyor 11, which feeds powder into weighing bowl 7. When modular platform scale 9 indicates the added powder has reached a set weight, feeding stops. Rotating cylinder 5 is activated, driving connecting rod 10, which in turn rotates weighing bowl 7 to a tilted position, pouring out the powder. This reciprocating rotation ensures a clean discharge, and the weighed powder is discharged from discharge port 6 for collection.

[0033] Since the protective shell 1 and the top cover 2 can shield the interference of wind and electrical signals, the modular platform scale 9 can weigh the powder in a relatively stable environment, thereby improving its weighing accuracy; the rotating cylinder 5 drives the weighing bowl 7 to tilt and pour out the powder, and a pneumatic discharge valve is installed on the modular platform scale 9, so there is no need to connect the discharge air pipe, avoiding the influence of the discharge air pipe on the modular platform scale 9, further improving its accuracy.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
