[0002] The flame retardant polyether composition is a polyether compound with flame retardant properties and is generally used to produce flame retardant polyurethane materials.

[0003] When the flame retardant polyether composition is produced, a weighing device is required to weigh the raw materials used in the production of the flame retardant polyether composition. For example, in the patent application CN214716398U in the prior art, the mixer body and the agitator arranged inside the mixer body are connected to the weighing plate through a supporting spring. Both sides of the weighing plate are provided with baffles connected to the auxiliary rod, one side of the weighing plate is provided with a slider connected to the limit groove, and the other side of the weighing plate is provided with a guide plate. Both sides of the weighing plate are provided with a clamping piece connected to the feed barrel, and the outer surface of the baffle is provided with a gram weight display screen. The material is poured into the feed barrel, and the material falls on the upper surface of the weighing plate. The weight of the material is displayed on the gram weight display screen. When the gram weight reaches the required amount, the weighing plate is separated from the feed barrel. At this time, the supporting spring contracts under the action of the gravity of the material to drive the weighing plate to move downward, and the material on the upper surface of the weighing plate flows into the mixer body through the guide plate, which is convenient for accurate quantity control and material feeding, and improves the material production effect.

[0004] However, since most of the raw materials for the production of the flame retardant polyether composition are in powder form, when pouring through a weighing plate, a portion of the raw materials may easily stick to the inner side of the weighing plate and cannot smoothly enter the interior of the flame retardant polyether composition production equipment. Subsequent manual cleaning of the stuck raw materials into the interior of the production equipment is required, thereby increasing the number of operating steps and reducing work efficiency.

[0005] Therefore, it is necessary to provide a weighing device for adding a flame retardant polyether composition to solve the above technical problems. Utility Model Content

A weighing device for adding a flame retardant polyether composition comprises: a mounting plate 1;

[0028] A weighing device 2, the weighing device 2 is fixedly mounted on the top of the mounting plate 1, a weighing plate 21 is fixedly mounted on the top of the weighing device 2, a fixing plate 22 is fixedly mounted on one end of the weighing plate 21, a driving motor 23 is fixedly mounted on one side of the fixing plate 22, a sliding groove 24 is provided on the top of the weighing plate 21, a screw rod 25 is fixedly mounted on the output end of the driving motor 23, a threaded sleeve 26 is threadedly connected to the outer side surface of the screw rod 25, and a push plate 27 is fixedly mounted on the top of the threaded sleeve 26;

[0029] The support plates 3 are fixedly mounted on both sides of one end of the top of the weighing plate 21, and a weighing frame 4 is rotatably connected in the middle of the two support plates 3. A fixed frame 42 is provided on the top of the weighing frame 4, and sliding rods 43 are fixedly mounted on both ends of the inner side surface of the fixed frame 42. A moving block 44 is slidably connected to the outer side surface of the sliding rod 43, and a scraper 45 is fixedly mounted on the bottom of the moving block 44.

[0030] One end of the screw rod 25 is rotatably connected to one end of the inner side surface of the slide groove 24 , and the bottom of the push plate 27 is attached to the top of the weighing plate 21 .

[0031] Both sides of the top of the weighing frame 4 are provided with moving grooves 41 , and both ends of the bottom of the fixed frame 42 are slidably connected to the inner side surfaces of the moving grooves 41 .

[0032] The side surface of the scraper 45 is in contact with the inner side surface of the weighing frame 4 , and the top of the push plate 27 is disposed at the bottom of the weighing frame 4 .

[0033] When the weighing device 2 is in use, the material dropped onto the inner side of the weighing frame 4 can be weighed, and the weighing weight can be preset when the weighing device 2 is in use;

[0034] One end of the weighing frame 4 is open, so that the material can slide out from the opening easily;

[0035] The bottom of the push plate 27 slides on the top of the weighing plate 21, so that when in use, the push plate 27 can be limited to prevent the push plate 27 from rotating;

[0036] When the powdered material is weighed, the fixed frame 42 quickly moves toward the opening of the weighing frame 4 , so that the bottom of the fixed frame 42 and the inner side of the movable groove 41 collide with each other, and the material on the scraper 45 is shaken off.

[0037] The working principle of a weighing device for adding a flame retardant polyether composition provided by the utility model is as follows:

[0038] When in use, the material needed for the flame retardant polyether composition falls to the top of the weighing frame 4. At this time, the material on the inner side of the weighing frame 4 is weighed by the weighing device 1. When the preset weight is reached, the material is stopped, and at the same time, the driving motor 23 is rotated to drive the screw rod 25 to rotate, so that the screw rod 25 is threadedly connected to the inner side of the threaded sleeve 26, and then the push plate 27 is moved from the open end of the weighing frame 4 to the other end, so that the open end of the weighing frame 4 is tilted downward, so that the material on the inner side of the weighing frame 4 slides out from the opening of the weighing frame 4, and at the same time, the fixed frame 42 will also move toward the opening of the weighing frame 4, and drive the scraper 45 to move at the same time, so as to scrape off the material adhering to the inner side of the weighing frame 4.

[0040] The structures such as the weighing frame 4, the fixed frame 42, the slide bar 43, the moving block 44, the scraper 45 and the pushing plate 27 cooperate with each other. When in use, the pushing plate 27 pushes the weighing frame 4 to tilt the weighing frame 4, and the scraper 45 scrapes the material on the inner side of the weighing frame 4, so as to avoid the material sticking to the inner side of the weighing frame 4. The user is required to manually clean a large area of ​​the inner side of the weighing frame 4, thereby reducing the operation steps and increasing work efficiency.
