Description

Technical Field

[0001] The invention belongs to the technical field of veterinary drug processing, in particular to a feeding mechanism of a powder veterinary drug dispensing machine. Background Art

[0002] Powdered veterinary drugs are dry powdered preparations made by crushing and evenly mixing one or more drugs. During the production process of powdered veterinary drugs, the crushed powdered veterinary drugs need to be transported to the filling machine through a feeding mechanism, and then loaded into packaging bags and bottles through the filling machine.

[0003] The patent with announcement number CN221396237U discloses a feeding mechanism of a powder veterinary drug filling machine, which relates to the field of veterinary drug processing technology, and aims to solve the problem that it is troublesome to connect the existing feeding port with the filling machine, and the powder is easily retained on the inner wall of the storage bin. It includes a storage assembly; the scraper assembly is installed inside the storage assembly; the feeding assembly is installed at the bottom of the storage assembly; the drive assembly is installed on the feeding assembly; the connecting assembly is installed on the top of the feeding assembly; the storage assembly includes: a powder veterinary drug storage bin and supporting feet; the bottom of the powder veterinary drug storage bin is a conical structure; there are four supporting feet in total, and the four supporting feet are fixedly installed at the bottom of the powder veterinary drug storage bin; this patent, because the telescopic tube is fixedly installed at the bottom of the feeding pipe, and the connecting flange is fixedly installed at the bottom of the telescopic tube, it is convenient for the staff to appropriately adjust the connection position, which is more convenient when using the filling machine.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The feeding mechanism of the powder veterinary medicine filling machine described in the present invention utilizes an adjustable splash-proof two-way discharging mechanism, and can adjust the distance between the two hard tubes according to the distance between the two receiving ports of the filling machine, so that the pipe openings of the two hard tubes are aligned with the receiving ports, and the two receiving ports of the filling machine can receive materials at the same time, thereby improving the production efficiency of the filling machine, and when the hard tube is extended into the receiving port of the filling machine, according to the size of the redundant space between the hard tube and the receiving port, the elastic cloth is stretched by the connecting rod, and the elastic cloth covers the redundant space between the receiving port and the hard tube.

In addition, when the elastic cloth contacts the upper end of the material receiving port, the hard pipe can be driven down again to make the lower end of the connecting rod slightly lower than the upper end surface of the material receiving port. Since a downward pressure is applied to the four corners of the elastic cloth, the elastic cloth will be tight to the material receiving port.

In addition, after the elastic cloth covers the upper end of the material receiving port, According to the distance between the hard tube and the inner wall of the material receiving port, the scraper one is driven to slide inside the scraper two, so that the end of the scraper one fits against the inner wall of the material receiving port, and the rotating ring is driven to rotate on the surface of the hard tube, so that the scrapers one and two form a scraping with the lower surface of the elastic cloth, so that the powdered veterinary drugs adhering to the lower surface of the elastic cloth can be made to fall off, thereby avoiding the situation where the powdered veterinary drugs adhere to the surface of the elastic cloth due to static electricity, friction and the like, thereby affecting the delivery amount of the powdered veterinary drugs, and also avoiding the situation where the powdered veterinary drugs remaining on the lower surface of the elastic cloth are mixed with other types of powdered veterinary drugs during subsequent use, thereby affecting the quality of the powdered veterinary drugs.

[0021] 2. The feeding mechanism of the powder veterinary drug filling machine described in the present invention can start motor 2 to drive the scraper bar to rotate when the powder veterinary drug is added into the storage bin.

[0045] Specifically, when the feeding mechanism of the existing powder veterinary drug filling machine is in use, it is connected to the filling machine through a connecting flange, and the powder veterinary drug in the feeding pipe 1 is conveyed to the filling machine by means of a telescopic tube. However, when the powder veterinary drug is conveyed to the receiving ports of filling machines of different models, since the specifications of the receiving ports of filling machines of different models may be different, there may be a large redundant space between the telescopic tube and the receiving port. When the powder veterinary drug enters the inner wall of the receiving port, it may splash out from the redundant space between the telescopic tube and the receiving port due to the impact force, thereby affecting the normal conveying of the powder veterinary drug. In addition, in order to improve the production efficiency, some filling machines are usually provided with two receiving ports for receiving materials at the same time. However, in the above-mentioned prior art, the powder veterinary drug is only discharged from a single telescopic tube, thereby affecting the production efficiency of the filling machine.

[0046] Therefore, in order to solve the above problems, this embodiment is used for a packaging machine with two material receiving ports, and the material receiving ports are cylindrical and receive materials in a vertical state; the powdered veterinary drug is added to the storage bin 3 and falls into the feeding pipe 1, and then, according to the spacing between the two material receiving ports, the motor 3 7 is used to drive the bidirectional threaded rod 10 to rotate, so that the two adjustment arms 8 slide in different directions at the same time, so as to adjust the spacing between the two hard tubes 14, and move the entire feeding pipe 1 so that the pipe openings of the two hard tubes 14 are aligned with the material receiving ports. , and the hard tube 14 coincides with the axis of the receiving port, and then the motor 4 13 is used to drive the connecting rod 2 12 and the connecting rod 1 11 to rotate, so that the slide plate 6 is lowered, and the two hard tubes 14 can be lowered and extended into the receiving port of the dispensing machine, and then the motor 1 2 is used to drive the feeding blade 36 to rotate, so that the powdered veterinary drug in the feeding pipeline 1 can be transported, so that the powdered veterinary drug enters the receiving port of the dispensing machine after passing through the two hoses 9 and the hard tube 14, so that the two receiving ports of the dispensing machine can receive materials at the same time, thereby improving the production efficiency of the dispensing machine;

[0047] After the hard tube 14 is inserted into the direct material port, there may be redundant space between the hard tube 14 and the inner wall of the material receiving port, and the powdered veterinary medicine may splash out of the material receiving port due to the impact force, thereby affecting the normal transportation of the powdered veterinary medicine. Therefore, in order to avoid this problem, after the hard tube 14 is inserted into the material receiving port of the filling machine, according to the size of the redundant space between the hard tube 14 and the material receiving port, the motor five 29 is used to drive the connecting rod four 28 on one side to rotate, so that the gear one 20 can be rotated, and under the rotation of the ring gear 25, multiple connecting rods four 28 and gear one 20 can rotate at the same time, and the connecting rod four 28 drives the connecting rod three 27 to rotate, so that multiple connecting rods 17 can be moved at the same time, and the adjusting rod 18 is adjusted. The limit rod 19 slides, and since each connecting rod 17 is connected to the four corners of the elastic cloth 16, the elastic cloth 16 will be stretched and its area can be adjusted until the elastic cloth 16 covers the redundant space between the material receiving port and the hard tube 14. At this time, the powdered veterinary medicine splashed by the impact will be intercepted by the elastic cloth 16, thereby avoiding the powdered veterinary medicine splashing out of the material receiving port and affecting the normal conveying work. In addition, compared with the method of setting a larger plate on the hard tube 14 to cover the material receiving port, the elastic cloth 16 has an adjustable area and expands from the inside to the outside, which can cover the material receiving port without causing the covering piece to conflict due to the small distance between the two hard tubes 14.

[0048] When the elastic cloth 16 covers the upper end of the material receiving port, since the elastic cloth 16 is relatively soft, when the powdered veterinary drug splashes, it may splash out from the joint between the elastic cloth 16 and the material receiving port due to the impact force. Therefore, in order to avoid this situation, after the elastic cloth 16 contacts the upper end of the material receiving port, the hard tube 14 can be driven down again, so that the lower end of the connecting rod 17 is slightly lower than the upper end surface of the material receiving port. Since a downward pressure is applied to the four corners of the elastic cloth 16, the elastic cloth 16 will be tight at the upper end of the material receiving port, and in the process of adjusting the area of ​​the elastic cloth 16, the adjustment The rod 18 will also drive the telescopic rod 24 to move, and the telescopic rod 24 will slide in the sliding sleeve 23, so the pressing rod 21 will also slide on the fixed rod 22, which will make the lower end of the pressing rod 21 always align with the middle of the edge of the elastic cloth 16, and when the lower end of the connecting rod 17 is lower than the upper end of the material receiving port, the pressing rod 21 will also press the edge of the elastic cloth 16 on the upper end surface of the material receiving port, and at this time, the four corners and edges of the elastic cloth 16 are all pressed tightly, thereby preventing the powdered veterinary drug from splashing out from the joint between the elastic cloth 16 and the material receiving port due to the impact force, which will affect the conveying work again;

[0049] Although the elastic cloth 16 can be used to block the splashing powdered veterinary drugs, due to the material characteristics of the elastic cloth 16, the powdered veterinary drugs are easily adhered to the surface of the elastic cloth 16 due to static electricity, friction and the like, which not only affects the delivery amount of the powdered veterinary drugs, but also causes the powdered veterinary drugs remaining on the lower surface of the elastic cloth 16 to mix with other types of powdered veterinary drugs when it is used later, thereby affecting the quality of the powdered veterinary drugs. Therefore, in order to avoid this situation, after the elastic cloth 16 covers the upper end of the material receiving port, according to the distance between the hard tube 14 and the inner wall of the material receiving port, the motor 7 35 is started to drive the threaded rod 34 to rotate, so that the scraper 1 30 is moved on the inner side of the scraper 2 33. Slide so that the end of the scraper 30 fits against the inner wall of the material receiving port. At this time, the motor 6 31 can be used to drive the gear 2 32 to rotate, so that the rotating ring 26 rotates on the surface of the hard tube 14, so that the scraper 1 30, the scraper 2 33 and the lower surface of the elastic cloth 16 form a scraping, which can make the powdered veterinary drug adhering to the lower surface of the elastic cloth 16 fall off, thereby avoiding the situation where the powdered veterinary drug adheres to the surface of the elastic cloth 16 due to static electricity, friction and the like, thereby affecting the delivery amount of the powdered veterinary drug, and also avoiding the situation where the powdered veterinary drug remaining on the lower surface of the elastic cloth 16 is mixed with other types of powdered veterinary drugs during subsequent use, thereby affecting the quality of the powdered veterinary drug.

[0050] In this embodiment, as 1 and Figure 2 As shown, a scraper strip 5 is rotatably provided on one side of the upper end of the storage bin 3, and the scraper strip 5 is in contact with the inner wall of the storage bin 3. A motor 2 4 is fixedly connected to one side of the upper end of the storage bin 3, and the output end of the motor 2 4 is fixedly connected to one side of the scraper strip 5.

[0051] Specifically, after the powdered veterinary drug is added to the storage bin 3, the motor 2 4 can be started to drive the scraper 5 to rotate. Since the scraper 5 is in contact with the inner wall of the storage bin 3, the powdered veterinary drug adhering to the inner wall of the storage bin 3 can be scraped off, thereby avoiding the situation where the powdered veterinary drug adheres to the inner wall of the storage bin 3 and affects the amount of powdered veterinary drug discharged.

[0052] Working principle: add powdered veterinary drugs into the storage bin 3 and drop them into the feeding pipe 1, start the motor 2 4 to drive the scraper 5 to rotate, and since the scraper 5 fits the inner wall of the storage bin 3, the powdered veterinary drugs adhering to the inner wall of the storage bin 3 can be scraped off, thereby avoiding the situation where the powdered veterinary drugs adhere to the inner wall of the storage bin 3 and affect the amount of powdered veterinary drugs discharged, and then, according to the spacing between the two receiving ports, use the motor 3 7 to drive the bidirectional threaded rod 10 to rotate, so that the two adjusting arms 8 slide in different directions at the same time, so as to adjust the spacing between the two hard tubes 14, and move the entire feeding pipe 1 so that the pipe openings of the two hard tubes 14 are aligned with the receiving port. The material port is located at the bottom of the feeding port, and the axis of the hard tube 14 coincides with the material receiving port. Then, the motor 4 13 is used to drive the connecting rod 2 12 and the connecting rod 1 11 to rotate, so that the slide plate 6 is lowered, and the two hard tubes 14 can be lowered and extended into the material receiving port of the dispensing machine. Then, the motor 1 2 is used to drive the feeding blade 36 to rotate, so that the powdered veterinary medicine in the feeding pipeline 1 can be transported, so that the powdered veterinary medicine enters the material receiving port of the dispensing machine after passing through the two hoses 9 and the hard tube 14, so that the two material receiving ports of the dispensing machine can receive the material at the same time, thereby improving the production efficiency of the dispensing machine. After the hard tube 14 is extended into the direct material port, there may be a gap between the hard tube 14 and the inner wall of the material receiving port. Redundant space, powdered veterinary drugs may splash out from the receiving port due to impact force, thereby affecting the normal transportation of powdered veterinary drugs. Therefore, in order to avoid this problem, after the hard tube 14 is extended into the receiving port of the dispensing machine, according to the size of the redundant space between the hard tube 14 and the receiving port, the motor 5 29 is used to drive the connecting rod 4 28 on one side to rotate, so that the gear 1 20 can be rotated, and under the rotation of the ring gear 25, multiple connecting rods 4 28 and gear 1 20 can be rotated at the same time, and the connecting rod 4 28 drives the connecting rod 3 27 to rotate, so that multiple connecting rods 17 can be moved at the same time, and the adjusting rod 18 slides on the limiting rod 19, and because each connecting rod The connecting rods 17 are connected to the four corners of the elastic cloth 16, so the elastic cloth 16 will be stretched and its area can be adjusted until the elastic cloth 16 covers the redundant space between the material receiving port and the hard tube 14. At this time, the powdered veterinary medicine splashed by the impact will be intercepted by the elastic cloth 16, thereby avoiding the powdered veterinary medicine splashing out of the material receiving port and affecting the normal conveying work. In addition, compared with the method of setting a larger plate on the hard tube 14 to cover the material receiving port, the area of ​​the elastic cloth 16 is adjustable and expands from the inside to the outside, which can cover the material receiving port without causing the collision of the covering parts due to the small distance between the two hard tubes 14.When the elastic cloth 16 covers the upper end of the material receiving port, since the elastic cloth 16 is relatively soft, when the powdered veterinary drug splashes, it may splash out from the joint between the elastic cloth 16 and the material receiving port due to the impact force. Therefore, in order to avoid this situation, after the elastic cloth 16 contacts the upper end of the material receiving port, the hard tube 14 can be driven down again, so that the lower end of the connecting rod 17 is slightly lower than the upper end surface of the material receiving port. Since a downward pressure is applied to the four corners of the elastic cloth 16, the elastic cloth 16 will be tight at the upper end of the material receiving port, and in the process of adjusting the area of ​​the elastic cloth 16, the adjusting rod 18 will also drive the telescopic rod 2 4 moves, and the telescopic rod 24 slides in the sliding sleeve 23, so the pressing rod 21 will also slide on the fixed rod 22, which will make the lower end of the pressing rod 21 always align with the middle of the edge of the elastic cloth 16, and when the lower end of the connecting rod 17 is lower than the upper end of the material receiving port, the pressing rod 21 will also press the edge of the elastic cloth 16 on the upper end surface of the material receiving port. At this time, the four corners and edges of the elastic cloth 16 are all pressed tightly, thereby preventing the powdered veterinary drug from splashing out from the joint between the elastic cloth 16 and the material receiving port due to the impact force, which will affect the conveying work again; although the elastic cloth 16 can be used to block the splashing powdered veterinary drug, However, due to the material properties of the elastic cloth 16, the powdered veterinary drugs are easily adhered to the surface of the elastic cloth 16 due to static electricity, friction and other reasons, which not only affects the delivery amount of the powdered veterinary drugs, but also causes the powdered veterinary drugs remaining on the lower surface of the elastic cloth 16 to mix with other types of powdered veterinary drugs during subsequent use, thereby affecting the quality of the powdered veterinary drugs. Therefore, in order to avoid this situation, after the elastic cloth 16 covers the upper end of the material receiving port, according to the distance between the hard tube 14 and the inner wall of the material receiving port, the motor 7 35 is started to drive the threaded rod 34 to rotate, so that the scraper 1 30 slides inside the scraper 2 33, so that the end of the scraper 1 30 The inner wall of the receiving port is fitted. At this time, the motor 6 31 can be used to drive the gear 2 32 to rotate, so that the rotating ring 26 rotates on the surface of the hard tube 14, so that the scraper 1 30, the scraper 2 33 and the lower surface of the elastic cloth 16 form a scraping, so that the powdered veterinary drug adhering to the lower surface of the elastic cloth 16 can be made to fall off, thereby avoiding the situation where the powdered veterinary drug adheres to the surface of the elastic cloth 16 due to static electricity, friction, etc., thereby affecting the delivery amount of the powdered veterinary drug, and also avoiding the situation where the powdered veterinary drug remaining on the lower surface of the elastic cloth 16 is mixed with other types of powdered veterinary drugs when the elastic cloth 16 is used later, thereby affecting the quality of the powdered veterinary drug. ;
