Description
Technical Field
[0001] The utility model relates to the technical field of lithium cobalt oxide processing, in particular to a lithium cobalt oxide raw material metering device. Background Art
[0002] Lithium cobalt oxide is the first commercialized positive electrode material for lithium-ion batteries. Lithium batteries made with lithium cobalt oxide have the advantages of stable structure, high capacity ratio, and outstanding comprehensive performance. The production and processing of lithium cobalt oxide is mainly through powder metallurgy, solid phase synthesis, solution method, gas phase synthesis method, etc. During the processing, the ratio between materials is crucial, which affects the quality and safety of the processed products. Therefore, it is necessary to weigh and measure the raw materials to avoid the occurrence of low quality and poor safety of processed products due to large errors in the proportion of raw material addition.
[0003] Existing lithium cobalt oxide raw material metering devices usually have auger, flip and other structures for unloading to facilitate material unloading. At the same time, in order to avoid residual raw materials inside the device, a scraping structure is usually set to scrape the residual raw materials out or facilitate cleaning. The superposition of the two sets of structures leads to higher equipment costs. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a lithium cobalt oxide raw material metering device to solve the technical problem of high cost.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lithium cobalt oxide raw material metering device, comprising a base and a metering cylinder, a push plate connected to the inside of the metering cylinder, a scraper ring fixed to the top of the push plate, a counterweight block fixed in the middle of the bottom of the push plate, and an anti-slip rope connected between the push plate and the metering cylinder.
[0006] By adopting the above technical solution, the metering cylinder flips over a certain angle after weighing and metering is completed. At this time, the push plate slides downward through the gravity combined with the gravity of the counterweight block, thereby pushing out the material in the metering cylinder for unloading. At the same time, the push plate drives the scraper ring to move downward, and the scraper ring scrapes the raw materials adhering to the inner wall of the metering cylinder and discharges them together. The anti-slip rope prevents the push plate and the scraper ring from falling off the metering cylinder. Since the push plate and the metering cylinder are extended, it is convenient to clean the raw materials adhering to the surface of the push plate and the scraper ring.
[0007] Furthermore, the push plate and the scraper ring are both slidably connected to the metering cylinder.
[0008] By adopting the above technical solution, the push plate slides downward by gravity combined with the gravity of the counterweight block, thereby pushing the material in the metering cylinder out for discharge. At the same time, the push plate drives the scraper ring to move downward, and the raw materials adhering to the inner wall of the metering cylinder are scraped off by the scraper ring and discharged together.
[0009] Furthermore, the cross section of the scraper ring is triangular.
[0010] By adopting the above technical solution, the push plate drives the scraper ring to move downward, and the raw materials adhering to the inner wall of the metering cylinder are scraped off by the scraper ring and discharged together, thereby reducing residue.
[0011] Furthermore, a plurality of anti-slip ropes are provided, and the plurality of anti-slip ropes are distributed in a circular array.
[0012] By adopting the above technical solution, the push plate slides downward to push the material in the metering cylinder out for unloading, and at the same time the raw materials adhering to the inner wall of the metering cylinder are scraped off by the scraper ring and discharged together, and the anti-falling rope is used to prevent the push plate and the scraper ring from falling off the metering cylinder.
[0013] Furthermore, a plurality of ribs are arranged at the lower part of the metering cylinder, and the plurality of ribs are distributed in a circular array.
[0014] By adopting the above technical solution and arranging a plurality of ribs at the lower part of the metering cylinder, the structural strength of the metering cylinder can be increased, and the weight of the raw material and the push plate can be prevented from deforming the bottom of the metering cylinder.
[0015] Furthermore, a weighing sensor is installed on the top of the base, and a weighing platform is connected to the top of the weighing sensor, and the measuring cylinder is connected to the inside of the weighing platform.
[0016] By adopting the above technical solution, the raw materials to be weighed and measured are input into the metering cylinder through the feeding unit, and after the feeding is completed, the raw materials in the metering cylinder are weighed and measured through the weighing sensor.
[0017] Furthermore, the metering cylinder is rotatably connected to the weighing platform.
[0018] By adopting the above technical solution, after the servo motor is started, the output end drives the metering cylinder to flip a certain angle through the engagement of the worm gear and the worm, so that the weighed and metered raw materials are poured out to complete the unloading.
[0019] Furthermore, a protrusion is provided in the middle of the top of the weighing platform, and the counterweight block abuts against the weighing platform.
[0020] By adopting the above technical solution, the counterweight block and the protrusion on the top of the weighing platform offset each other to share the pressure, thereby preventing the outer ring supporting surface of the push plate from being subjected to greater pressure.
[0021] Furthermore, a servo motor is installed on one side of the weighing platform.
[0022] By adopting the above technical solution, the servo motor is used to drive the metering cylinder to flip and pour out the raw materials to complete the material unloading. After the material unloading is completed, the output end is flipped to reset the metering cylinder to facilitate the next metering work.
[0023] Furthermore, a worm gear is connected to one side of the metering cylinder, and a worm is connected to the output end of the servo motor.
[0024] By adopting the above technical solution, after the servo motor is started, the output end drives the metering cylinder to flip to a certain angle through the engagement of the worm wheel and the worm, and at the same time, the engagement of the worm wheel and the worm plays the effect of deceleration and torque increase, so that the servo motor drives the metering cylinder containing the raw material to flip, and the worm wheel and the worm cooperate to form a self-locking function to prevent the metering cylinder from rotating at will after the servo motor is turned off.
[0025] In summary, the utility model mainly has the following beneficial effects:
[0026] The utility model is provided with a metering cylinder, a pushing plate, a scraping ring, a counterweight and an anti-slipping rope. After the weighing and metering are completed, the metering cylinder flips over a certain angle. At this time, the pushing plate slides downward by the gravity cooperating with the gravity of the counterweight, so that the material in the metering cylinder is pushed out for unloading. At the same time, the pushing plate drives the scraping ring to move downward, and the raw materials adhered to the inner wall of the metering cylinder are scraped off and discharged together by the scraping ring. The anti-slipping rope is used to prevent the pushing plate and the scraping ring from falling off the metering cylinder. Since the pushing plate and the metering cylinder are extended, it is convenient to clean the raw materials adhered to the surfaces of the pushing plate and the scraping ring. The utility model has the advantages of simple structure, convenient operation, low cost, easy cleaning and effective reduction of residues. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0033] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:
[0034] A lithium cobalt oxide raw material metering device, such as Figure 1-Figure 4 As shown, it includes a base 1 and a metering cylinder 7, a plurality of ribs are arranged at the lower part of the metering cylinder 7, and the plurality of ribs are distributed in a ring array to increase the structural strength; a push plate 8 is connected to the inside of the metering cylinder 7 to push out the material in the metering cylinder 7 for unloading; a scraper ring 9 is fixed on the top of the push plate 8, and the cross-section of the scraper ring 9 is triangular. The push plate 8 and the scraper ring 9 are both slidably connected to the metering cylinder 7, and the push plate 8 drives the scraper ring 9 to move downward, and the raw materials adhered to the inner wall of the metering cylinder 7 are scraped off and discharged together through the scraper ring 9; a counterweight block 10 is fixed in the middle of the bottom of the push plate 8, and the push plate 8 slides downward through the gravity of the counterweight block 10; an anti-slip rope 11 is connected between the push plate 8 and the metering cylinder 7, and a plurality of anti-slip ropes 11 are provided, and the plurality of anti-slip ropes 11 are distributed in a ring array to prevent the push plate 8 and the scraper ring 9 from falling off the metering cylinder 7.
[0035] See also Figure 1-Figure 4 In the above embodiment, a weighing sensor 3 is installed on the top of the base 1, and a weighing platform 2 is connected to the top of the weighing sensor 3. The metering cylinder 7 is connected to the inside of the weighing platform 2. After the loading is completed, the raw materials in the metering cylinder 7 are weighed and measured by the weighing sensor 3; a servo motor 4 is installed on one side of the weighing platform 2, and the output end of the servo motor 4 is connected to the metering cylinder 7 to facilitate driving the metering cylinder 7 to flip.
[0036] See also Figure 1-Figure 4 In the above embodiment, the metering drum 7 is rotatably connected to the weighing platform 2. After the metering drum 7 is turned over, the raw materials are discharged by gravity; a protrusion is provided in the middle of the top of the weighing platform 2, and the counterweight block 10 abuts against the weighing platform 2. The counterweight block 10 abuts against the protrusion on the top of the weighing platform 2 to share the pressure, thereby preventing the outer ring support surface of the push plate 8 from being subjected to greater pressure. Embodiment 2:
[0037] On the basis of the above-mentioned embodiment 1, the stability of the device during operation is increased.
[0038] See also Figure 1 , Figure 3 and Figure 4 In the above embodiment, a worm wheel 6 is connected to one side of the metering drum 7, and a worm 5 is connected to the output end of the servo motor 4. The worm wheel 6 cooperates with the worm 5 to form a self-locking function to prevent the metering drum 7 from swinging under force when loading materials. When unloading materials, the worm wheel 6 and the worm 5 mesh to reduce speed and increase torque, so that the servo motor 4 can drive the metering drum 7 filled with raw materials to flip.
[0039] The implementation principle of the utility model is as follows: first, the raw materials to be weighed and measured are input into the metering cylinder 7 through the feeding unit. At this time, the worm wheel 6 and the worm 5 cooperate to form a self-locking to prevent the metering cylinder 7 from swinging under force. After the loading is completed, the raw materials in the metering cylinder 7 are weighed and measured by the weighing sensor 3. At the same time, the counterweight block 10 and the top protrusion of the weighing platform 2 are offset to share the pressure, so as to prevent the outer ring support surface of the push plate 8 from being subjected to a large pressure;
[0040] After the weighing and metering is completed, the staff turns on the servo motor 4. After the servo motor 4 is started, the output end drives the metering cylinder 7 to flip a certain angle through the meshing of the worm wheel 6 and the worm 5. At the same time, the meshing of the worm wheel 6 and the worm 5 has the effect of decelerating and increasing torque, so that the servo motor 4 drives the metering cylinder 7 filled with raw materials to flip. After the metering cylinder 7 flips, the gravity cooperates with the gravity of the counterweight block 10 to make the push plate 8 slide downward, thereby pushing the material in the metering cylinder 7 out for unloading. At the same time, the push plate 8 drives the scraper ring 9 to move downward, and the raw materials adhered to the inner wall of the metering cylinder 7 are scraped off by the scraper ring 9 and discharged together. The anti-slip rope 11 prevents the push plate 8 and the scraper ring 9 from falling off the metering cylinder 7. Since the push plate 8 and the metering cylinder 7 are extended, it is convenient for the staff to clean the raw materials adhered to the surface of the push plate 8 and the scraper ring 9.
