[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention arranges the packaging bag bodies in a row in the material storage rack, and then, under the action of the first spring and the pushing plate, the packaging bag bodies are pushed forward in the material storage rack, and the first suction cup group generates suction to adsorb the packaging bag bodies in the front, and then the first suction cup group and the packaging bag bodies are controlled to rotate forward one hundred and eighty degrees with the driving shaft as the center, so that the taken packaging bag bodies move to the rear end of the second suction cup group, and then the second suction cup group is controlled to start, and then the first suction cup group is controlled to close, at this time, the transfer of the packaging bag bodies is completed, so that the packaging bag bodies move to the second suction cup group, and then the driving motor is reversed to drive the first suction cup group to reset through the connecting arm, and then the rotating shaft is controlled to rotate, so that the rotating disk, the second suction cup group and the packaging bag body are driven to rotate ninety degrees together, so that the packaging bag body enters the material preparation state, thereby completing the effect of automatic material taking and material preparation.

[0017] 2. The present invention controls the operation of the second cylinder to move the third suction cup group to both sides of the packaging bag body, and then controls the opening of the third suction cup group and the closing of the second suction cup group so that the third suction cup group can be adsorbed on both sides of the packaging bag body, and the sliding frame is driven by the second cylinder to move forward in the sliding groove. During the movement, under the action of the guide shaft and the guide shell, the sliding arm will gradually expand synchronously to both sides in the sliding frame, thereby making the third suction cup group relatively far away. Since the third suction cup group adsorbs the two ends of the packaging bag respectively, after the third suction cup group is relatively far away, the packaging bag body can be expanded and opened. Subsequently, after the opened packaging bag body is moved to the feeding position, a certain amount of medicine can be loaded into it.

[0018] 3. In the present invention, as the packaging bag body passes through the correction plates, the spacing between the correction plates gradually decreases, which gradually promotes the opening of the packaging bag body to fit together, so that the opening of the packaging bag body is closed, and wrinkles are avoided at the opening of the packaging bag body, thereby ensuring the sealing effect of the packaging bag body. Subsequently, the sealing operation can be performed, and finally the hot pressing plate is controlled to heat press the opening of the packaging bag, thereby achieving the effect of sealing the packaging bag body.

[0032] like Figure 1-10 As shown, in one embodiment, a packaging device for veterinary drug production capable of quantitative bagging is proposed, comprising a machine base 1, a support frame 101 is mounted on the upper end of the machine base 1, a material preparation assembly 2 is mounted on the upper end of the support frame 101, the material preparation assembly 2 comprises a material taking mechanism 21 and a material loading mechanism 22, the material taking mechanism 21 comprises a material storage rack 211, a guide rack 213 and a material pushing plate 212, the material storage rack 211 is mounted on the support rack 101, the material pushing plate 212 is slidably connected in the material storage rack 211, the guide rack 213 is mounted on the surface of the material storage rack 211, a slider 214 is mounted on the surface of the material pushing plate 212, the slider 214 is slidably connected to the guide rack 213, a first spring 215 is fixedly connected between the slider 214 and the guide rack 213, and a packaging bag body 3 is clamped between the material pushing plate 212 and the material storage rack 211;

[0033] The feeding mechanism 22 includes a rotating seat 221, a rotating disk 228, a connecting arm 223, a connecting block 226, a first suction cup group 227 and a second suction cup group 2211. The rotating seat 221 is installed on the support frame 101. The driving shaft 222 is rotatably connected inside the rotating seat 221. The connecting arm 223 is installed on the driving shaft 222. The driving shaft 222 is connected to the output end of a driving motor 224 installed on the surface of the rotating seat 221. A sliding rod 225 is installed on the surface of the connecting arm 223. The connecting block 226 is slidably connected to the circumferential surface of the sliding rod 225. The first suction cup group 227 is installed on the surface of the connecting block 226. The rotating disk 228 is rotatably connected to the support frame 101 through the rotating shaft 229. A mounting frame 2210 is installed on the upper end of the rotating disk 228, and the second suction cup group 2211 is installed on the mounting frame 2210.

[0034] An expansion mechanism 4 and a sealing mechanism 5 are provided on the machine base 1 . The expansion mechanism 4 is used to expand the packaging bag body 3 , and the sealing mechanism 5 is used to seal the packaging bag body 3 .

[0035] When the embodiment of the present invention is actually used, the packaging bag bodies 3 are neatly placed in the storage rack 211, and then the packaging bag bodies 3 are pushed forward in the storage rack 211 under the action of the first spring 215 and the pushing plate 212, and then the first suction cup group 227 is controlled to start, and the first suction cup group 227 generates suction to adsorb the packaging bag body 3 at the front, and then the driving motor 224 is controlled to operate, and the driving motor 224 drives the connecting arm 223 to rotate through the driving shaft 222, thereby driving the first suction cup group 227 and the packaging bag body 3 to rotate forward 180 degrees, so that the removed packaging bag body 3 moves to the rear end of the second suction cup group 2211, and at this time, after the packaging bag body 3 at the front is taken away, the pushing plate 212 will push the packaging bag body 3 to move forward, and the front material is taken. The position is replenished, and then the second suction cup group 2211 is controlled to start, and then the first suction cup group 227 is controlled to close. At this time, the transfer of the packaging bag body 3 is completed, so that the packaging bag body 3 is moved to the second suction cup group 2211, and then the driving motor 224 is reversed, so that the first suction cup group 227 is reset through the connecting arm 223, and then the rotating shaft 229 is controlled to rotate, and the rotating disk 228, the second suction cup group 2211 and the packaging bag body 3 are driven to rotate ninety degrees together, so that the packaging bag body 3 enters the material preparation state, and then the automatic material taking and preparation effect is completed, which is convenient for the subsequent material taking and expansion of the expansion mechanism 4. After the expanded packaging bag body 3 is quantitatively loaded with drugs, the packaging bag body 3 can be sealed by the sealing mechanism 5 to complete the packaging effect of the drugs.

[0036] like Figure 4 and 5 As shown, as a preferred embodiment of the present invention, a first cylinder 2212 is installed in the connecting arm 223, the output end of the first cylinder 2212 is fixedly connected to the connecting block 226, a damping rubber ring 2213 is installed in the slider 214, and the damping rubber ring 2213 is slidably connected to the guide frame 213.

[0037] When the embodiment of the present invention is actually applied, the output end of the first cylinder 2212 is controlled to extend to push the connecting block 226 to move backward, so that the first suction cup is attached to the packaging bag body 3. Then, after the first suction cup group 227 starts to absorb the packaging bag body 3, the second section of the output end of the first cylinder 2212 is controlled to extend, so that all the packaging bag bodies 3 in the storage rack 211 are moved backward. Then, the position of the second section of the output end of the first cylinder 2212 is controlled to be reset. At this time, the speed of the first spring 215 pushing the push plate 212 to reset can be slowed down by the action of the damping rubber ring 2213. At this time, the packaging bag body 3 absorbed by the first suction cup group 227 will not be in a squeezed state, and the friction between the first suction cup group 227 and other packaging bag bodies 3 will be reduced, which is convenient for taking out the packaging bag body 3. Then, the driving motor 224 can be operated to enable the first suction cup group 227 to drive the packaging bag body 3 is taken out from the material storage rack 211 by rotation. When the first suction cup group 227 drives the packaging bag body 3 to rotate ninety degrees, the output end of the first cylinder 2212 is controlled to retract and reset to avoid the first suction cup group 227 from interfering with the second suction cup group 2211 in the process of rotating one hundred and eighty degrees. Finally, when the first suction cup group 227 is opposite to the second suction cup group 2211, the output end of the first cylinder 2212 is controlled to extend again to make the packaging bag body 3 adsorbed on the first suction cup group 227 move forward so that it is attached to the second suction cup group 2211. Subsequently, the second suction cup group 2211 is started and the first suction cup group 227 is closed, thereby completing the transfer of the packaging bag body 3. After the packaging bag body 3 is transferred, the output end of the first cylinder 2212 can be controlled to retract and reset, and then the driving motor 224 is controlled to operate so that the first suction cup group 227 is reset and ready for operation.

[0038] like Figure 6 and 7 As shown, as another preferred embodiment of the present invention, the expansion mechanism 4 includes a sliding groove 401, a sliding frame 402, a sliding arm 403, a third suction cup group 404, a guide shaft 406, a guide shell 405 and a second cylinder 407. The sliding groove 401 is opened on the upper end surface of the machine base 1, the sliding frame 402 is slidably connected in the sliding groove 401, the sliding arm 403 is slidably connected in the sliding frame 402, the third suction cup group 404 is installed on the end surface of the sliding arm 403, the guide shell 405 is installed on the machine base 1, the guide shaft 406 installed in the sliding arm 403 is slidably connected to the guide shell 405, and the output end of the second cylinder 407 installed at the lower end of the machine base 1 is fixedly connected to the sliding frame 402.

[0039] In actual application of the embodiment of the present invention, when the packaging bag body 3 is moved to the second suction cup group 2211 and rotated 90 degrees, the second cylinder 407 is controlled to operate, and the second cylinder 407 drives the sliding frame 402 to move backward in the sliding groove 401, so that the third suction cup group 404 moves to both sides of the packaging bag body 3, and then the third suction cup group 404 is controlled to open and the second suction cup group 2211 is closed, so that the third suction cup group 404 can be adsorbed on both sides of the packaging bag body 3, and then the second cylinder 407 drives the sliding frame 402 to move backward in the sliding groove 401. The frame 402 moves forward in the sliding groove 401. During the movement, under the action of the guide shaft 406 and the guide shell 405, the sliding arm 403 will gradually expand to both sides in the sliding frame 402, thereby making the third suction cup group 404 relatively far away. Since the third suction cup group 404 respectively adsorbs two sides of the packaging bag, after the third suction cup group 404 is relatively far away, the packaging bag body 3 can be expanded and opened. Subsequently, after the opened packaging bag body 3 is moved to the feeding position, a certain amount of medicine can be loaded therein.

[0040] like Figure 6 and 9 As shown, as another preferred embodiment of the present invention, a guide groove 408 is provided on the lower end surface of the base 1, a tooth block 409 is slidably connected in the guide groove 408, a gear 4010 is installed on the circumferential surface of the rotating shaft 229, the gear 4010 is meshed with the tooth block 409, a traction rod 4011 is installed at the rear end of the sliding frame 402, a traction block 4012 slidably connected to the traction rod 4011 is installed at the lower end of the tooth block 409, and a second spring 4013 is installed between the traction block 4012 and the sliding frame 402.

[0041] In actual application of the embodiment of the present invention, when the sliding frame 402 moves forward to the limit position, the traction rod 4011 will pull the traction block 4012 to move, thereby driving the tooth block 409 to move forward, and the tooth block 409 will drive the gear 4010 to rotate, and then drive the rotating disk 228 to rotate through the rotating shaft 229, so that the second suction cup group 2211 rotates to face backward, thereby receiving the material. When the sliding frame 402 moves backward, the traction rod 4011 will release the traction force on the traction block 4012. At this time, under the action of the second spring 4013, the second spring 4013 will push the tooth block 409 to move backward through the traction block 4012, thereby driving the gear 4010 to rotate, and then through the action of the rotating shaft 229 and the rotating disk 228, the second suction cup group 2211 can be controlled to rotate instantly, so that the second suction cup group 2211 with the adsorbed packaging bag body 3 rotates ninety degrees to face the side, and the third suction cup group 404 can be moved backward to both sides of the packaging bag body 3 to complete the adsorption of both sides of the packaging bag body 3.

[0043] In actual application of the embodiment of the present invention, when the opened packaging bag body 3 moves to the position directly below the discharge tube 601, the external medicine is extracted through the discharge tube 601, and then a fixed amount of medicine is output in the packaging bag body 3 so that it enters the packaging bag body 3. Then, by closing the third suction cup group 404, the packaging bag body 3 loaded with the medicine will fall down, and then continue to move forward to perform the final sealing operation.

[0045] In actual application of the embodiment of the present invention, when the packaging bag body 3 filled with medicine moves forward, it will pass through the correction plate 503. Since the distance between the correction plates 503 gradually decreases, it will gradually promote the opening of the packaging bag body 3 to fit together, so that the opening of the packaging bag body 3 is closed, so that the opening of the packaging bag body 3 is prevented from wrinkling, thereby ensuring the sealing effect of the packaging bag body 3, and then the sealing operation can be performed.

[0047] In actual application of the embodiment of the present invention, after the opening of the packaging bag body 3 is closed, the third cylinder 504 is controlled to operate, and the third cylinder 504 will control the pressure block 505 to move toward the opening of the packaging bag, so that the hot pressing plate 506 performs hot pressing on the opening of the packaging bag, thereby achieving the effect of sealing the packaging bag. After the sealing is completed, the third cylinder 504 is controlled to reset, and then the sealed packaging bag body 3 will pass through between the correction plates 503 to complete the unloading.
