[0032] It should be noted that in some optional embodiments, a motor for driving the drive wheel 124 can be arranged in the driving table 121, which can also be a servo motor, so that the subsequent driving of the drive wheel 124 can drive the weighing part 12 to slide along the track of the chute 132 to both sides, and three groups of electronic scales corresponding to the three groups of inner grooves can be arranged on the top of the driving table 121 below the three groups of inner grooves, so as to implement feedback of the weight of p-tolyl benzoic acid currently located in the inner groove. In addition, the electronic scales in the driving table 121 can be electrically connected with the motor and the electromagnetic valve 27 respectively, so that the subsequent feeding and discharging of the material distribution part 123 can be implemented by the electronic scales to feedback the weight, and the overall translation of the weighing part 12 can drive the inner groove not carrying p-tolyl benzoic acid to be moved to the position below the electromagnetic valve 27.

[0033] In specific implementation, first, the operator can pour the p-tert-butyl benzoic acid raw material into the down feeder 22, and wake up the motor 23 on the down feeder assembly 2 through the controller. In some optional embodiments of the application, the controller can be arranged at any position of the p-tert-butyl benzoic acid weighing and packaging device which is convenient for the operator to operate, and the controller can be an MCU (Microcontroller Unit) chip to control the whole p-tert-butyl benzoic acid weighing and packaging device. The controller is in electrical connection with the p-tert-butyl benzoic acid weighing and packaging device, and the electrical connection includes wired connection and wireless connection. The wireless connection includes but is not limited to Bluetooth connection, WiFi, IF radio frequency, zigbee, and the wired connection includes but is not limited to USB line connecting the p-tert-butyl benzoic acid weighing and packaging device with the controller. Then, the motor 23 drives the output shaft 24 and the material guiding scraper 25 to rotate axially, which can stir the p-tert-butyl benzoic acid raw material to make the raw material particles uniform and avoid clogging caused by raw material clumping to affect the subsequent raw material transmission. At the same time, the operator can open the electromagnetic valve 27 to implement the down feeder weighing operation by observing the raw material state in real time. Before that, the operator needs to control the position of the sub-weighing part 12 through the controller to make one group of inner grooves located directly below the down feeder assembly 2. Then, when the electromagnetic valve 27 is opened, the raw material can be pushed out between the partitions 26 to fall into the sub-weighing assembly 1 through the continuously rotating material guiding scraper 25, so as to avoid the raw material from being stuck at the partitions 26 during the down feeding process. It should be noted that the gap between the partitions 26 is matched with the material guiding scraper 25, and the active track of the material guiding scraper 25 covers at least half of the material guiding scraper 25. Then, when the raw material enters the sub-weighing assembly 1 through the down feeder assembly 2, the raw material can be guided to fall into the inner recess through the material receiving table 122, and then the electronic scale embedded in the driving table 121 and located below the inner groove can feedback the weight of the raw material at the top in real time, and the electromagnetic valve 27 can be closed according to the weight requirement to realize equal down feeding. The material distributing part 123 after weighing can be translated to either side of the discharging part 3, and the operator can drive the discharging part 3 to push the raw material in the material distributing part 123 into the packaging auxiliary part 14. At the same time, other material distributing parts 123 without raw material can be translated to below the down feeder assembly 2. The above discharging operation of the discharging part 3 can also complete the raw material supplement at other positions of the material distributing part 123 to improve the work efficiency of raw material weighing and guiding and realize continuous operation.

[0034] In addition, in some optional embodiments of the present invention, besides electronic scales, the measurement operation can also be achieved by measuring the internal volume of the inner groove, provided that the uniformity of the raw material particles is ensured. It is understood that there is no need to repeatedly weigh the raw material on the dispensing section 123; simply filling the inner groove is sufficient to ensure the corresponding amount of raw material. For example, the opening time of the solenoid valve 27 can be controlled to estimate the material feeding. During this estimated feeding process, the feeding amount must exceed 10% of the total quantitative raw material to avoid insufficient raw material during subsequent material control operations. Furthermore, since the p-tert-butylbenzoic acid raw material itself will form a conical stack when it is placed on the dispensing section 123, it needs to be spread flat on the inner groove of the dispensing section 123 after the raw material is placed. Specifically, in the solenoid valve 27... After closing, a drive request is sent to the drive platform 121, which in turn wakes up the internal motor to drive the drive wheel 124 to move the weighing component 12 to either the left or right side, so that the concave part containing the raw material moves to the corresponding position of the material control component 4. Then, the material control component 4 is opened, and the second output component 41 drives the second output rod 42 to push the material control push plate 43 towards the raw material. The bottom of the material control push plate 43 and the top of the distributing part 123 are not in contact, and there is a gap between them. This gap can be understood as a quantitative space for accommodating the raw material. The final amount of raw material left depends on the size of the gap. During the process, the material control push plate 43 can push the raw material pile to distribute it evenly in the inner groove. In order to prevent the raw material from being pushed into the adjacent inner groove during the pushing process, such as Figure 5As shown, the blocking blocks are also extended on both sides of the output direction of the material control push plate 43, which ensures the uniformity of the raw material spreading while limiting its spreading to both sides. Then, the excess raw material is uniformly pushed to the material guide groove 5 near the discharge part 3 by the material control push plate 43, and is guided into the recycling part 15. About 10% of the excess raw material is recycled. In some optional embodiments of the present application, a stepped conveying device for connecting the top discharging assembly 2 of the discharging assembly 2 can be additionally provided at the recycling discharging hopper 152 of the recycling part 15, so as to recycle the recycled raw material into the discharging assembly 2, ensure the continuity of the raw material weighing and packaging work, and then open the discharge part 3 after the recycling of the material control push plate 43. The working principle is the same as that of the material control part 4. The raw material spread in the inner groove is pushed out to the side near the material control part 4 by the discharge part 3, guided into the packaging auxiliary part 14 along the material guide groove 5 on this side, and guided out to the bottom packaging device along the discharging hopper 143 to complete the weighing and packaging operation of the raw material. In some optional embodiments, the discharging hopper 143 at the bottom of the packaging auxiliary part 14 can be provided with a packaging device. The packaging device specifically comprises a conveying device composed of a conveying belt and an infrared sensor. After the position of the discharging hopper 143 is positioned by infrared, the container containing p-t-butyl benzoic acid is correspondingly conveyed to the position directly below the discharging hopper 143, and waits for the material receiving and packaging operation. The above description of the packaging device is understood by those skilled in the art and is a relatively basic packaging device in the industry, which will not be described in detail here.

[0035] In summary, the driving wheel 124 in the weighing assembly 1 drives the material receiving table 122 to horizontally translate, and the material weighing and discharging part 123 is sequentially loaded with raw material under the discharging assembly 2, and then horizontally translates between the discharging part 3 and the material control part 4, and sequentially completes the weighing and discharging operation of p-t-butyl benzoic acid on the material weighing and discharging part 123. In this operation, the weighing and discharging method is adopted, which ensures the accuracy of weighing while avoiding the time delay caused by weighing, effectively ensures the continuity of the weighing and discharging process of the raw material, improves the production efficiency of the raw material, and solves the problem that the existing weighing and packaging device for p-t-butyl benzoic acid usually implements single discharging and weighing operation by the discharging device, which reduces the weighing efficiency and affects the subsequent production efficiency of p-t-butyl benzoic acid.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application.
