[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 An automated batching and weighing device for resin production in this embodiment includes a support plate 1, an mounting plate 3 between the left and right inner walls of the support plate 1, two weighing bins 4 on the mounting plate 3, and two storage bins 6 and a protective mechanism 7 on the top of the support plate 1.

[0023] A motor 401 is provided on one side of each of the two weighing chambers 4. The output shafts of the two motors 401 extend into the interior of the weighing chamber 4 and are connected to a rotating plate 402. A weighing device 403 is provided on the top of each of the two rotating plates 402.

[0024] Inside the weighing chamber 4, the motor 401 drives the rotating plate 402 to rotate, which, together with the weighing device 403 on the top, enables precise weighing and transfer of resin raw materials; the storage tank 6 stores the raw materials, and the quantitative valve 601 on the discharge pipe precisely controls the feed amount to ensure the accuracy of the batching.

[0025] The protective mechanism 7 includes a protective cover 701, a fan 702, and a treatment box 703. A filter element 704 is movably installed inside the treatment box 703. A sealing plate 705 is provided on the front side of the filter element 704. Limiting elements 706 are provided on both the left and right sides of the treatment box 703. An exhaust pipe 711 is provided on the rear side of the treatment box 703.

[0026] The limiting component 706 in the protective mechanism 7 includes a fixing block 71, a rotating block 72, a telescopic rod 73, a locking block 74, and a spring 75, which realizes the fixing and unlocking of the sealing plate 705, ensuring the stability of the filter element 704 during installation and facilitating replacement.

[0027] In the protective mechanism 7, the protective cover 701 encloses the dust and volatile gases generated at the feed hopper 404. The fan 702 draws in the polluted gas through the suction pipe 707 and sends it into the treatment box 703 through the conveying pipe 708. The filter element 704 in the treatment box 703 intercepts dust with the filter screen and adsorbs volatile organic compounds with the activated carbon plate. The sealing plate 705, together with the limiting element 706, ensures the sealing of the treatment box 703. The purified gas is discharged from the exhaust pipe 711, which solves the problem of insufficient air purification in the existing device and protects the production environment and personnel health.

[0028] In actual use of the automated batching and weighing device for resin production, firstly, according to the resin production formula requirements, the opening of the quantitative valve 601 is controlled to allow the resin raw materials in the storage tank 6 to fall through the discharge pipe and feed hopper 404 into the weighing chamber 4 onto the weighing device 403 for weighing. When the weighing device 403 displays that the set weight has been reached, the motor 401 starts, driving the rotating plate 402 to rotate, causing the material in the weighing chamber 4 to be discharged from the outlet and transferred to the designated location. During the weighing process of the raw materials, dust and volatile organic compounds are generated. At this time, the protective cover 701 surrounds the area of ​​the feed hopper 404 to reduce the diffusion of polluting gases. The fan 702 starts, sucking the polluting gases in the protective cover 701 through the suction pipe 707, and sending them into the treatment box 703 through the conveying pipe 708. The polluting gases first pass through the filter screen in the filter element 704 to intercept the powdery dust particles. Then, the gas passes through an activated carbon plate to adsorb volatile organic compounds and remove irritating odors. The purified gas is then discharged into the external environment through the exhaust pipe 711 at the rear of the treatment box 703. After the filter element 704 has been used for a period of time, its filtration and adsorption effects will decrease, and it needs to be replaced. Pull the locking block 74 in the limiting part 706 outward, and the spring 75 will expand, causing the locking block 74 to disengage from the slot 76 on the sealing plate 705. Then, rotate the telescopic rod 73 outward, and then open the sealing plate 705. The old filter element 704 is then pulled out from the installation cavity 709 of the treatment box 703 along the slide 710 for replacement. The sealing plate 705 is then installed back in its original position. After that, the telescopic rod 73 is rotated back and the locking block 74 is released. Under the elastic force of the spring 75, the locking block 74 re-engages into the slot 76, fixing the sealing plate 705 and ensuring the airtightness of the treatment box 703.

[0029] In summary, this automated batching and weighing device for resin production, through the installation of a protective mechanism 7, in which a protective cover 701 encloses the dust and volatile gases generated at the feed hopper 404, a fan 702, a suction pipe 707, and a conveying pipe 708 draw the polluted gases into a treatment box 703, a filter screen in a filter element 704 intercepts dust, an activated carbon plate adsorbs volatile organic compounds, a sealing plate 705 and a limiting element 706 ensure the airtightness of the treatment box 703, and the purified gas is discharged from an exhaust pipe 711, effectively solves the problem of insufficient air purification in existing devices, improves the production environment, and protects the health of operators.

[0030] Furthermore, by setting up a weighing bin 4, a motor 401, a rotating plate 402, a weighing device 403, a storage tank 6, and a metering valve 601, the amount of resin raw material fed can be precisely controlled, and the raw materials can be accurately weighed and transferred, ensuring the accuracy of batching and improving the precision of resin production and product quality.
