Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical equipment, and particularly to a medicine feeding device. Background Art

[0002] In the automated production of pharmaceuticals, when products are added to a vibrating bowl, there are certain defects in the prior art during the product conveying process; under normal feeding conditions, there is no transition when the products fall from the vibrating bowl into the feeding track through the arc track, resulting in frequent damage to the products during the material dropping process. This not only reduces production efficiency but also has a negative impact on the quality of the finished products.

[0003] In addition, there are different impacts on products of different specifications. For example, when the products are too small, the gap to be adjusted between the feeding track and the vibrating bowl will become smaller, which increases the difficulty of adjustment; when the products are too large, if the gap between the vibrating bowl and the feeding track is not adjusted properly during material dropping, it will affect the accuracy of material dropping. Traditional feeding devices are inefficient and cannot achieve efficient material dropping when facing products of these different specifications.

[0004] Due to the lack of an effective connection device, there is a discontinuity problem between the vibrating bowl and the feeding track, resulting in low production efficiency and unable to meet the requirements of modern pharmaceutical production lines for high-efficiency and automated production. Summary of the Invention

[0005] The purpose of the present invention is to provide a medicine feeding device to solve the problems of discontinuity between the vibrating bowl and the feeding track, damage to products during feeding by a conventional vibrating bowl feeder, and misalignment between the arc track and the feeding track in the vibrating bowl.

Detailed implementation manners

[0023] Such as Figures 1-3As shown in the figure, a medicine feeding device includes a vibrating feeder base 1 installed on the equipment. Above the vibrating feeder base 1, a vibrator 2 is installed. Above the vibrator 2, a vibrating disc 3 is installed. When the medicine packaging machine needs this device, the vibrating feeder base 1 can be installed on the equipment. Since this device will vibrate during operation, in order to make this device more stable during operation, the vibrating feeder base 1 needs to be fixed on the required equipment with screws. The control device of the vibrator 2, such as a power switch and a device for adjusting the vibration frequency, is installed in the vibrating feeder base 1. When we turn on the power and start the switch, the vibrator 2 will start to work. Since the connection between the vibrator 2 and the vibrating feeder base 1 is not a rigid connection, when the vibrator 2 vibrates, the vibrating feeder base 1 will not vibrate accordingly. The vibrating disc 3 and the vibrator 2 need to be fixed with screws because it is necessary to ensure that the vibrator 2 drives the vibrating disc 3 when vibrating, so as to play the role of a vibrating feeder. A vibrating disc edge guard 4 for preventing materials from falling is provided at the edge of the vibrating disc 3. When materials are added to the vibrating disc 3, due to the vibrating disc edge guard 4, the materials will not be shaken outside the feeder by the vibrating feeder during operation. When the vibrating disc 3 is working, the materials will circle along the vibrating disc edge guard 4 in the vibrating disc 3. When the materials pass through the arc track 7, they will fall into the first material guiding groove of the arc track 7. At this time, the materials will continue to move forward along the first material guiding groove until they reach the discharging port of the arc track 7. A discharging track 11 is provided below the vibrating disc 3. A flexible transition mechanism is provided between the vibrating disc 3 and the discharging track 11. The discharging port 12 of the discharging track 11 is arranged above the feeding table track 15. The materials pass through the discharging track 11 and reach the discharging port 12 and finally fall into the feeding table track 15. A discharging control mechanism is provided on one side of the discharging track 11.

[0024] Specifically, in this embodiment, two arc tracks 7 are provided on the vibrating disc 3, and correspondingly, two flexible transition mechanisms and two discharging tracks 11 are also provided.

[0025] The flexible transition mechanism includes a number of transition hoses 8 arranged in parallel. An arc track 7 is provided on the vibrating disc 3. A number of first material guiding grooves are opened on the arc track 7. A number of second material guiding grooves 11-1 are opened in the discharging track 11. The upper end of the transition hose 8 corresponds to the first material guiding groove, and the lower end of the transition hose 8 corresponds to the second material guiding groove 11-1. The upper and lower ends of the number of transition hoses 8 are respectively connected to the vibrating disc 3 and the discharging track 11 through hose connectors 10 and flat key pressing seat 9.

[0026] By setting up a flexible transition mechanism, feeding can be better, and the adjustment time between the blanking guide rail and the feeding table guide rail can be reduced; a transition hose 8 is added between the blanking port of the arc track 7 and the blanking track 11, so that there is a buffer section between the vibrating bowl 3 and the blanking track 11. When the vibrating bowl 3 vibrates, if the gap between the blanking track 11 and the vibrating bowl 2 is not adjusted properly or the material is too long, the material will be damaged at the joint. Moreover, adding the transition hose 8 can also reduce the time for adjusting the alignment of the blanking port of the arc track 7 with the slot on the blanking track 11, greatly reducing the difficulty of adjusting the feeder, and at the same time improving the production efficiency of the product. The transition hose 8 is fixed on the hose interface 10 and the flat key pressing plate seat 9 by set screws, so it will not fall off due to the vibration of the vibrating bowl 3; the blanking track 11 is fixed on the supporting cross bar 17 by screws. If other products of the same specification need to be replaced, first loosen the set screws, remove the transition hose 8, and then remove the screws fixed on the supporting cross bar 17 to remove the blanking track 11 for replacement.

[0027] A first guide plate 5 and a second guide plate 6 are arranged on the vibrating bowl 3 and at the entrance of the arc track 7. The first guide plate 5 and the second guide plate 6 are respectively arranged on both sides of the arc track 7; when the material enters the arc track 7, because a first material guiding groove is processed on the arc track 7, the material will fall into the transition hose 8 along the first material guiding groove. When the material is too little, the first guide plate 5 and the second guide plate 6 will gather the material into the arc track 7.

[0028] A blanking track cover plate 13 is arranged on one side of the blanking track 11, and a blanking port cover plate 14 is arranged on one side of the blanking port 12 to prevent the material from falling out of the blanking track 11 and the blanking port 12 during the feeding process.

[0029] In addition, in order to improve the feeding stability, the blanking track 11 needs to be fixed on the equipment; a supporting mechanism is arranged on the other side of the blanking track 11. The supporting mechanism includes a supporting vertical plate 16 fixed on the equipment. The top of the supporting vertical plate 16 is connected with a supporting cross bar 17, and a fine adjustment mechanism is arranged between the supporting cross bar 17 and the blanking track 11.

[0030] The fine adjustment mechanism includes an adjusting support 23. The adjusting support 23 is arranged on the side of the blanking track 11. An adjusting screw is installed on the adjusting support 23, and the other end of the adjusting screw is threadedly connected with the blanking track 11; when adjusting the blanking track 11, the position of the blanking track 11 can be finely adjusted by rotating the adjusting screw on the adjusting support 23 to change the extending length of the adjusting screw, so that the blanking port 12 can be more conveniently aligned with the slot on the feeding table guide rail 15.

[0031] The blanking control mechanism includes two control seat guide rods 18 arranged in parallel. One end of the two control seat guide rods 18 is connected to the same cylinder seat 19. The other end of the control seat guide rod 18 is connected to the blanking track 11. A movable material control needle seat 20 is installed on the control seat guide rod 18 through a linear bearing. A material control needle 22 is installed on the material control needle seat 20. The material control needle 22 can be inserted into the through hole 11-2 of the blanking track 11. A driving member 21 for driving the movement of the material control needle seat 20 is arranged on the cylinder seat 19, and the driving member 21 can be a cylinder. When the material passes through the blanking guide rail 11, when the plates of the equipment have not been adjusted properly, the extension and retraction of the cylinder can be controlled to drive the movement of the material control needle 22 to block the flow of the material in the feeding track, thereby controlling the feeding and stopping of the material; when feeding is not required, the cylinder is started, and the piston rod of the cylinder extends, which will drive the material control needle seat 20 to be pushed forward. The material control needle seat 20 will move along the direction of the control guide rod 18 without deviation, thereby pushing the material control needle 22 forward. At this time, the material control needle 22 will penetrate into the through hole 11-2 at the lower part of the second material guide groove 11-1 of the blanking track 11 to block the falling of the material, thereby controlling whether the feeder starts feeding.

[0032] A dust treatment mechanism is further arranged on the vibrating disk 3. The dust treatment mechanism includes a plurality of dust falling holes opened on the vibrating disk 3 and a powder receiving box installed below the dust falling holes. Specifically, in this embodiment, there are two dust falling areas on the vibrating disk 3, and a plurality of dust falling holes are opened in each dust falling area. A first powder receiving box 24 and a second powder receiving box 25 are respectively installed below the two dust falling areas. The first powder receiving box 24 and the second powder receiving box 25 are fixed on the vibrating disk 3 by screws. Just loosen the fixing screws and remove the powder receiving box to pour out the dust in it; when the materials in the vibrating disk 3 are round pieces or shaped pieces, these materials are formed by powder stamping, so there may be residual powder when they are added to the vibrating disk 3. At this time, the design of the dust falling holes on the vibrating disk plays a very good role. When the dust passes through these dust falling holes, it will leak from those dust falling holes and fall into the first powder receiving box 24 and the second powder receiving box 25. The role of the powder receiving box is to prevent the dust from floating everywhere and affecting the cleanliness. If more dust is generated, a vacuum cleaner can be externally connected to the powder receiving box, so that the dust in the vibrating disk can be better removed.

[0033] The working process of the present invention is as follows:

[0034] Add materials into the vibrating bowl 3, start the vibrator 2 to work. The vibrator 2 will vibrate together with the vibrating bowl 3. During the vibration process of the vibrating bowl 3, the materials in the vibrating bowl 3 will rotate counterclockwise along the edge of the vibrating bowl 4. When the materials pass through the arc track 7, they will fall into the first feeding groove of the arc track 7. At this time, the materials will continue to move forward along the first feeding groove until they reach the discharge opening of the arc track 7. The materials will flow into the transition hose 8, then enter the feeding track 11 through the transition hose 8, and then flow from the feeding track 11 to the feeding table track 15.

[0035] The present invention is to better enable materials to enter the feeding track from the circular vibrating bowl. It abandons the rigid connection method and conducts the conversion in a smooth and gentle manner. It breaks through the limitations of traditional rigid feeding and has a flexible adjustable conveying structure; the present invention can avoid damage to the materials during the blanking process; the present invention accurately controls the flow speed and landing point of the materials, builds a flexible bridge between production links, accurately and efficiently completes the conveying and transfer of materials, and provides stable support for the production process.

[0036] The embodiments described above are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
