DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference below Figure 1-Figure 4 , the implementation of the weighing and feeding device proposed in the embodiment of the utility model is described in detail.

[0027] The weighing and feeding device according to the embodiment of the utility model is suitable for weighing during the feeding process of the powder feeding device 3 , and comprises: a counterweight block 1 and a weighing assembly 2 .

[0028] Specifically, the powder feeding device 3 has a first bracket 31 and a first mounting plate 32, the first mounting plate 32 is connected to the first bracket 31, and the first mounting plate 32 and the first bracket 31 jointly define an installation space 33; the counterweight block 1 is arranged in the installation space 33, and the weighing assembly 2 has a sensing module 21 and a carrying plate 22, the carrying plate 22 is arranged outside the installation space 33 to place a plurality of test tubes 5, the sensing module 21 is arranged on the counterweight block 1, and the sensing module 21 is connected to the carrying plate 22 to weigh the powder added to the plurality of test tubes 5 on the carrying plate 22.

[0029] That is to say, the first bracket 31 and the first mounting plate 32 jointly define an installation space 33, so that the counterweight block 1 is conveniently arranged in the installation space 33, and is independently arranged with the powder feeding device 3 without being connected, thereby preventing the powder feeding device 3 from transmitting vibration to the weighing component 2 on the counterweight block 1 during operation. The powder feeding device 3 will generate slight vibrations during the process of adding powder or transporting the test tube 5. The counterweight block 1 can increase the vibration resistance of the weighing component 2, thereby ensuring that the weighing component 2 accurately weighs the powder added to the test tube 5.

[0030] Therefore, the weighing component 2 is arranged on the counterweight block 1, so that the weighing component 2 can reduce vibration. By arranging the counterweight block 1 in the installation space 33 of the powder feeding device 3, it can be avoided that the powder feeding device 3 transmits vibration to the counterweight block 1 and the weighing component 2 on the counterweight block 1 during the feeding process. The weighing feeding device can weigh the powder added to the test tube 5 and is not affected by the vibration generated by the powder feeding device 3 during the feeding process, thereby ensuring the accuracy of weighing.

[0031] For the installation of the counterweight 1, the weighing assembly 2 includes a second bracket 24, the second bracket 24 is arranged in the installation space 33, the counterweight 1 is arranged on the second bracket 24, and the height of the second bracket 24 is adjustable. It can be understood that the installation of the counterweight 1 can be facilitated by the second bracket 24, and the height of the second bracket 24 can be adjusted to facilitate the adjustment of the height of the counterweight 1, thereby adjusting the height of the weighing assembly 2, so that the powder feeding device 3 places the test tube 5 on the carrier plate 22, and then adds the powder into the test tube 5, thereby facilitating the weighing of the added powder. Among them, the height of the second bracket 24 can be adjusted by the foot, and the foot can directly contact the ground.

[0032] For the installation of the weighing assembly 2 and the counterweight 1, the powder feeding device 3 has a second mounting plate 34, the second mounting plate 34 is detachably connected to the first mounting plate 32, the second mounting plate 34 has a through hole 341, and the bearing plate 22 is connected to the sensing module 21 through the through hole 341. It can be understood that after the first bracket 31 and the first mounting plate 32 are installed, the second bracket 24, the counterweight 1 and the sensing module 21 can be installed and placed from the top of the installation space 33, and then the second mounting plate 34 is connected to the first mounting plate 32, and finally the bearing plate 22 is connected to the sensing module 21 through the through hole 341. The installation of the weighing device on the powder feeding device 3 can be facilitated to improve the installation efficiency; at the same time, the second mounting plate 34 can be set to facilitate the shielding of the installation space 33 to prevent the material from falling into the weighing assembly 2 and affecting the weighing accuracy. Among them, the second mounting plate 34 can be connected to the first mounting plate 32 by screws, and part of it is connected to the first bracket 31.

[0033] For the installation of the load-bearing plate 22, the weighing assembly 2 includes a first connecting block 23, which is inserted into the through hole 341, one end of the first connecting block 23 is connected to the load-bearing plate 22, and the other end of the first connecting block 23 is connected to the sensing module 21. It can be understood that in order to prevent the powder feeding device 3 from transmitting vibration to the weighing assembly 2 during operation, there is a gap between the counterweight block 1 and the second mounting plate 34. The first connecting block 23 passes through and connects the load-bearing plate 22 and the sensing module 21, which can prevent the load-bearing plate 22 and the sensing module 21 from contacting the second mounting plate 34, thereby effectively isolating the transmission of vibration, thereby improving the weighing accuracy. Among them, the through hole 341 and the connecting block can be a clearance fit.

[0034] For the addition of powder, the powder feeding device 3 has a silo loading device 35 and a powder material silo 36. The silo is suitable for storing powder, and the silo loading device 35 is suitable for connecting the powder material silo 36 to add the powder in the powder material silo 36 to the test tube 5 on the carrier plate 22. It can be understood that the silo loading device 35 transfers the test tube 5 at the test tube 5 placement station to the carrier plate 22, and the silo loading device 35 then loads the powder material silo 36 at the silo placement station and transfers it to the top of the carrier plate 22, and adds the powder in the powder material silo 36 to the test tube 5. The carrier plate 22 transmits the weight change to the sensing module 21, and the sensing module 21 cooperates with the host to calculate the added powder in real time and control the silo loading device 35 to add the powder to the powder material silo 36.

[0035] For the connection between the first bracket 31 and the second bracket 24, a second connecting block 4 is connected between the bottom of the first bracket 31 and the bottom of the second bracket 24. It can be understood that, since the powder feeding device 3 may have a slight position change during operation, the first bracket 31 and the second bracket 24 are connected from the bottom by the second connecting block 4, which facilitates the connection between the weighing feeding device and the powder feeding device 3, and the positions of the weighing feeding device and the powder feeding device 3 can be relatively fixed. At the same time, the connection from the bottom can minimize the transmission of vibration from the powder feeding device 3 to the weighing feeding device during operation, thereby ensuring the relative position of the two and the weighing accuracy. Among them, the number of the second connecting blocks 4 can be four.

[0036] As for the counterweight 1, the counterweight 1 is a marble platform. It can be understood that the use of marble as the counterweight 1 has the advantage of not being easily deformed, and can ensure the accurate weighing of the weighing assembly 2 while playing the role of counterweight shock absorption. Among them, a handle can be provided on the marble to facilitate hoisting during installation.

[0037] For the cooperation between the test tube 5 and the carrier plate 22, the carrier plate 22 is provided with a plurality of positioning holes 21, and the plurality of positioning holes 21 are suitable for placing a plurality of test tubes 5 in a one-to-one correspondence. It can be understood that, through the setting of the positioning holes 21 of the carrier plate 22, it is convenient to abut the lower end of the test tube 5 in the positioning hole 21, so as to position the test tube 5, so as to facilitate the addition of powder into the test tube 5. Among them, the plurality of test tubes 5 can be fixed in the middle and upper positions of the plurality of test tubes 5 by the test tube 5 fixing frame, and the powder feeding device 3 transfers the test tube 5 to the carrier plate 22 by clamping the test tube 5 fixing frame, and positions the lower ends of the plurality of test tubes 5 in the plurality of positioning holes 21 one by one.
