Detailed implementation manners

[0029] Example 1

[0030] A traditional Chinese medicine weighing and packing device for traditional Chinese medicine pharmacists, comprising: a bottom plate 1, a paper feeding device 2, a support assembly 3, a pressing mechanism 4, and an adsorption assembly 5; a support assembly 3 is fixedly installed in the middle of the upper end of the bottom plate 1, a paper feeding device 2 is fixedly arranged on the bottom plate 1 on one side of the support assembly 3, a pressing mechanism 4 is fixedly installed on one side of the paper feeding device 2, and an adsorption assembly 5 is fixedly arranged inside the pressing mechanism 4;

[0031] The pressing mechanism 4 can be used to pack the medicine, and during the packing process, the cyclic operation of a single second motor 41 is used to ensure that there is no interference during packing. At the same time, considering the problem that the paper used for packing rebounds when not continuously pressed, resulting in packing failure, specifically in this embodiment, the pressing mechanism 4 includes a second motor 41 and a pressing assembly 42; the second motors 41 are arranged in a circumferential array on the bottom plate 1, and the output shaft of the second motor 41 is fixedly installed with the pressing mechanism 4. The pressing assembly 42 includes: a rotating rod 421, a contact rod 422, and a spring 423; the rotating rod 421 is fixedly installed on the output shaft of the second motor 41, the contact rod 422 is rotatably installed on the side wall of the rotating rod 421, and the inner side of the contact rod 422 is connected to the rotating rod 421 through the spring 423; by controlling the forward or reverse rotation of the motor, the rotating rod 421 is driven to drive the contact rod 422 to press and pack the paper for packaging traditional Chinese medicine; during the movement, the second motor 41 drives the rotating rod 421 to rotate. During the rotation, the contact rod 422 also rotates, and is pressed and installed from the inner side of the rear end of the paper. The contact rod 422 drives the inward installation and the contact rod 422 contacts the traditional Chinese medicine inside; in this way, the packing process is realized. At the same time, in order to prevent interference between the pressing mechanisms 4 during the packing process, the contact rod 422 is arranged on the rotating rod 421. After the contact rod 422 presses one corner of the paper, when the paper rebounds, the contact rod 422 can limit its position. When the next rotating rod 421 rotates, it can just press the paper after the previous rotating rod 421 presses it. The effect of overlapping packing is achieved through repeated movements. At the same time, in this embodiment, in order to make the paper coming out of the paper feeding device 2 be located in the center and not deviate when placed, the initial position of the pressing mechanism 4 can be set at a certain angle with the bottom plate 1. The setting of this angle is between 30° and 45°. When the angle is too small, less than 30°, it cannot play a supporting role, which will cause the paper to deviate downward and shift, and it cannot form a situation where the middle is low and the surrounding is high well. When the weighed traditional Chinese medicine falls, it may splash outwards, resulting in waste; when the angle is too large, greater than 45°, the diameter of the upper end of the paper used for receiving will become smaller. When the weighed traditional Chinese medicine falls, it may not fall into the paper, which will also cause waste. Therefore, according to the actual verification of the paper, setting it between 30° and 45° is a better choice

[0032] In addition, in this embodiment, in order to further elaborate on the effect of the contact rod 422 on the paper during pressing, specifically, an extension block 4221 is provided at the end of the contact rod 422. The extension block 4221 is arranged perpendicular to the ground. A notch 4211 is formed on the side of the rotating rod 421 close to the contact rod 422. The notch 4211 is adapted to the size of the extension block 4221. By pressing the contact rod 422 against the spring 423, it can be basically attached to the paper containing the drug. At the same time, since after weighing the drug and then starting to press it with the pressing mechanism 4, the rotating rod 421 cannot be directly rotated to a position parallel to the bottom plate 1. After rotating to the parallel position, the drug may be directly moved to one side, resulting in spillage. Therefore, the angle between the contact rod 422 and the rotating rod 421 is between 30° and 60°, and at the same time, the rotation angle of the second motor 41 driving the rotating rod 421 is controlled to be less than 90°. By setting specific angles, it can meet the needs of different packages. It can meet the corresponding requirements without using a sensor. And because the quality of the medicinal materials themselves is relatively light, the accuracy requirements for the sensor are higher, which undoubtedly also increases the use cost. Therefore, a sensor is not applicable.

[0033] In addition, in this embodiment, in order to ensure that the paper can be completely fixed inside the pressing mechanism 4, an adsorption assembly 5 is provided inside the pressing mechanism 4. The adsorption assembly 5 includes a negative pressure pump 51 and an adsorption disc 52. The negative pressure pump 51 is fixedly installed at the bottom of a circular groove 12 formed on the bottom plate 1, and the adsorption disc 52 is fixedly installed at the center of the circular groove 12, and the negative pressure pump 51 is connected to the adsorption disc 52. By providing the adsorption assembly 5, the paper can be adsorbed. On the one hand, it can play a fixing role, and on the other hand, it can also make the paper form a structure with a lower middle and higher sides, which is convenient for receiving the drug.

[0034] Embodiment 2

[0035] In this embodiment, an extension mechanism 22 is fixedly installed on the left side of the paper output device 2. The paper output device 2 can be achieved by existing technologies, and the internal structure will not be described in detail here. Its principle is similar to the paper output structure of a printer and belongs to the prior art. In addition, the extension mechanism 22 includes a first motor 221, a friction wheel 222, and a paper output block 223. The paper output block 223 is fixedly installed outside the paper outlet of the paper output device 2. The paper output block 223 has an L-shaped structure. The friction wheel 222 is movably installed inside the paper output block 223. The first motor 221 is installed outside the paper output block 223 and the friction wheel 222 is installed on the output shaft. After the paper output device 2 outputs the paper, under the action of the friction wheel 222, the paper continues to move forward until it gradually enters above the pressing mechanism 4. At the same time, in this embodiment, in order to ensure that the paper can smoothly move onto the pressing mechanism 4 under the action of the friction wheel 222, a support block 43 is fixedly arranged at the upper end of the bottom plate 1 between the extension mechanism 22 and the pressing mechanism 4. Thin plates 431 are symmetrically installed on both side walls at the upper end of the support block 43, and the thin plates 431 are inclined downward. By providing the support block 43, it can serve as a support and effectively prevent the paper from falling downward under the influence of gravity during the movement process, resulting in a situation where it cannot move smoothly.

[0036] Embodiment 3

[0037] In this embodiment, the support device serves as the support for the entire device, and at the same time, the drug can be weighed through the support device. Specifically, the support assembly 3 includes a balance rod 33, a vertical rod 34, and a cross rod 35. The vertical rod 34 is fixedly installed at the upper middle part of the vertical rod 34. The balance rod 33 is movably installed at the upper end of the vertical rod 34. A weighing line 32 is fixedly installed on one side of the balance rod 33. A measuring device 31 is fixedly arranged at the end of the weighing line 32. The measuring device 31 is fixedly installed on the bottom plate 1. The other end of the balance rod 33 is fixedly installed with a support frame 37. The support frame 37 has a cross structure. A weighing pan 371 is movably installed at one end of the support frame 37. The drug is weighed through the weighing pan 371. At the same time, the measuring device 31 is a tension meter type structure, with a scale 311 provided on the outside. At the same time, the measuring device is a transparent structure. The measuring device 31 belongs to the prior art and will not be described in detail here.

[0038] In addition, in this embodiment, the cross bar 35 is fixedly installed at the middle side end of the vertical rod 34, and a retaining wall 38 is fixedly installed at the end of the cross bar 35. The retaining wall 38 is directly below the support frame 37. The retaining wall 38 is a closed annular structure with unequal diameters up and down. Through the retaining wall 38, the weighed medicine can be effectively conveyed downward, and it can be limited to the upper end of the pressing mechanism 4, which is convenient for feeding the medicine onto the paper. In addition, in order to further prevent the medicine placed on the tilting weighing pan 371 from being completely restricted within the retaining wall 38, an extension plate 381 is fixedly installed on the outer side of the upper end of the retaining wall 38. The extension plate 381 is an open-loop structure and extends along the upper end of the retaining wall 38. Through the extension plate 381, the medicine can be blocked inside, preventing the situation where the medicine is thrown off due to the initial velocity brought by the weighing pan 371 when the quick-turning weighing pan 371 is flipped.

[0039] Embodiment 4

[0040] In this embodiment, a glue - applying mechanism 36 is fixedly arranged on the lower side of the middle part of the cross bar 35, and the glue - applying mechanism 36 faces the upper end of the extending mechanism 22. The glue - applying mechanism 36 can apply glue to the paper for packing drugs, and firmly fix the paper with glue. Specifically, the glue - applying mechanism 36 includes: a fixed cylinder 361, a glue storage cylinder 363, an electric push rod 364, and a glue - applying plate 368. The fixed cylinder 361 is fixedly installed on the cross bar 35. An electric push rod 364 is fixedly installed at the upper end inside the fixed cylinder 361. The end of the push rod of the electric push rod 364 is movably installed with the glue - applying plate 368, and a torsion spring is arranged at the movable position. By arranging the torsion spring, the glue - applying plate 368 can be reset. On both sides of the electric push rod 364, glue storage cylinders 363 are symmetrically and fixedly installed on the side wall of the fixed cylinder 361. A glue injection pipe 365 is arranged outside the glue storage cylinder 363. The glue injection pipe 365 can be used to convey glue, and the end of the glue injection pipe 365 is fixedly connected to the glue - applying plate 368. At the lower end of the glue storage cylinder 363, a fixed block 366 is fixedly arranged on the side wall of the fixed cylinder 361. A pull wire 367 is fixedly arranged on the fixed block 366, and the end of the pull wire 367 is fixedly installed at the end of the glue - applying plate 368. Touch switches 362 are symmetrically and fixedly installed on both sides at the lower end of the fixed cylinder 361. The opening and closing of the glue - applying plate 368 are passively controlled by controlling the telescopic movement of the electric push rod 364 to apply glue to the paper for packaging. During movement, when the paper moves to a certain position (the position can be determined by the running time of the motor in the paper - discharging device 2 of the sensor, which belongs to the prior art), the electric push rod 364 starts. As the electric push rod 364 pushes, the glue - applying plate 368 gradually moves downward. During the downward movement, under the action of the pull wire 367, the glue - applying plate 368 gradually opens until it touches the touch switch 362. At this time, the electric push rod 364 stops moving. At this time, it just moves to the position of the paper. At this time, the glue - discharging pump 3631 starts to convey the glue through the glue injection pipe 365 to the glue - applying plate 368 to apply glue to the paper. A plurality of glue - applying holes 3681 are arranged on the inner side of the glue - applying plate 368. The glue injection pipe 365 communicates with the glue - applying holes 3681, and the other end of the glue injection pipe 365 is connected to the glue - discharging pump 3631 arranged at the bottom end inside the glue storage cylinder 363. A glue injection port 3632 is arranged at the upper end of the glue storage cylinder 363, and the glue injection port 3632 extends to the upper end of the cross bar 35. By arranging the glue injection port 3632, the used glue can be further supplemented.

[0041] The working principle of the present invention is as follows: when weighing and packing drugs, directly place the required drugs on the weighing pan 371 and observe the reading in the measuring device 31 for measurement. After weighing, directly flip the weighing pan 371 to pour out the drugs; then start the main switch (not shown in the figure), the paper output device 2 outputs the paper. When the paper is output to the corresponding position, the gluing mechanism 36 moves accordingly to glue the paper. After completion, the pressing mechanism 4 starts to press and release in sequence clockwise from the first one to pack the paper. When reaching the last pressing mechanism 4, the second motor 41 stops for a period of time (for waiting for the glue to dry to form a sticking effect) and then opens, and the weighing and packing can be completed.
