Description

Technical Field

[0001] The invention belongs to the technical field of pill processing, and in particular relates to a pill rolling device. Background Art

[0002] Among the Tibetan medicine preparations, pills are usually the main type. Pills refer to spherical or quasi-spherical preparations made of fine powder of medicinal materials or medicinal material extracts plus suitable adhesive excipients. Pills are often prepared using a rotary tilting pill rolling machine. The main structure of the rotary tilting pill rolling machine consists of a frame, a drum connected to the frame for tilting rotation, and a driving device for driving the drum to rotate. During preparation, the powder is added to the drum, which is then driven to rotate by a driving device. During this process, an adhesive is sprayed in, so that the powder will aggregate and bond together to form pills. After the pills are prepared, they need to be taken out. The common way to take them out is for workers to scoop them out using a container. However, this way of taking medicine is more physically demanding and less efficient. Therefore, in response to the above problems, we have proposed a pill rolling device. Summary of the invention

[0008] When the barrel cover is not connected to the lower end of the discharge barrel, the stirring paddle will abut against the inner bottom wall of the barrel body under the action of gravity. In this state, the end of the stirring paddle away from the retaining barrel will fit against the inner side wall of the barrel body, the upper end of the retaining barrel will withdraw from the barrel body, and the lower end of the push rod will extend downward from the discharge barrel.

[0009] Furthermore, the side surface of the retaining cylinder is provided with a limiting protrusion, the inner wall of the discharge cylinder is provided with a limiting sliding groove which matches the limiting protrusion and extends along the axial direction of the discharge cylinder, and the limiting protrusion is slidably assembled in the limiting sliding groove.

[0010] Furthermore, the limiting protrusion is in the shape of a long strip that matches the limiting slide groove. When the stirring paddle abuts against the inner bottom wall of the barrel body under the action of gravity, the upper end of the limiting protrusion will be flush with the upper end of the limiting slide groove.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Reference Figure 1-Figure 6 As shown, a shot rolling device of this embodiment includes a frame 1, a drum 2 connected to the frame 1 and a driving device for driving the drum 2 to rotate, and also includes a stirring and discharging assembly 3 and a drum cover 4. The drum 2 includes a barrel body 21 and a discharging drum 22 connected to the lower side of the drum 2 and coaxially arranged with the drum 2. The drum cover 4 is detachably connected to the lower end of the discharging drum 22.

[0030] In this embodiment, the angle between the axis of the drum 2 and the horizontal plane is about 45 degrees.

[0031] In this embodiment, the cylinder cover 4 is threadedly connected to the lower end of the discharge cylinder 22 by a screw connection. When the cylinder cover 4 and the discharge cylinder 22 are threadedly connected together, the cylinder cover 4 will seal the lower end of the discharge cylinder 22. When the cylinder cover 4 is removed, the lower end of the discharge cylinder 22 will be conductive.

[0032] The stirring and discharging assembly 3 includes a push rod 31, a stirring paddle 32 and a retaining cylinder 33. The retaining cylinder 33 is axially slidably assembled in the discharging cylinder 22 and cannot axially rotate relative to the discharging cylinder 22. The stirring paddle 32 is fixedly connected to the upper end of the retaining cylinder 33 and is located in the discharging cylinder 22. The height direction of the stirring paddle 32 extends along the axial direction of the retaining cylinder 33. The push rod 31 is fixedly connected to the stirring paddle 32 and is located in the discharging cylinder 22.

[0033] When the cylinder cover 4 is connected to the lower end of the discharge cylinder 22, the lower end of the push rod 31 will abut against the cylinder cover 4 under the action of gravity. In this state, the upper end of the retaining cylinder 33 will extend into the barrel body 21, and the lower end of the stirring paddle 32 will form a gap with the inner bottom wall of the barrel body 21.

[0034] When the barrel cover 4 is not connected to the lower end of the discharge barrel 22, the stirring paddle 32 will abut against the inner bottom wall of the barrel body 21 under the action of gravity. In this state, the end of the stirring paddle 32 away from the retaining barrel 33 will fit against the inner side wall of the barrel body 21, the upper end of the retaining barrel 33 will withdraw from the barrel body 21, and the lower end of the push rod 31 will extend downward from the discharge barrel 22.

[0035] In the initial state, the barrel cover 4 is installed at the lower end of the discharge barrel 22 to close the lower end of the discharge barrel 22. When preparing pills, the powder is added to the barrel body 21. Since the barrel body 21 is tilted, the powder entering the barrel body 21 will fall below the barrel body 21, that is, between the bottom wall and the side wall, under the action of gravity. After the powder is added, the driving device is started to drive the drum 2 to rotate around the axis so that the powder is circulated and turned at the lower part of the barrel body 21. At this time, the adhesive is sprayed into the barrel body 21 to make the powder agglomerate and bond to form pills.

[0036] In the process of the barrel body 21 rotating and continuously rolling the pills, since the baffle cylinder 33 cannot rotate axially relative to the discharge cylinder 22, the baffle cylinder 33 will be driven to rotate by the discharge cylinder 22, so that the baffle cylinder 33 will drive the stirring paddle 32 to rotate. When the stirring paddle 32 rotates to the lower part of the barrel body 21, it will turn over the powder or semi-formed pills in the lower part of the barrel body 21, so that the powder is fully in contact with the adhesive or the semi-formed pills, thereby increasing the pill forming speed.

[0037] It is worth mentioning that since there is a gap between the stirring paddle 32 and the inner bottom wall of the barrel body 21 in this state, and the stirring paddle 32 also remains inclined with respect to the barrel body 21, the powder or pills lifted by the stirring paddle 32 will directly slide down from the rear side of the stirring paddle 32 (close to the inner bottom wall of the barrel body 21), that is, they will not be lifted to a high place, thereby preventing the stirring paddle 32 from guiding the unformed pills into the discharge barrel 22.

[0038] In addition, during the ball rolling process of the barrel body 21, the upper end of the blocking cylinder 33 will extend from the discharge barrel 22 into the barrel body 21. In this way, even if there is a small amount of powder or pills that fall after rotating to a high place with the bottom wall of the barrel body 21, they can be blocked by the side wall of the blocking cylinder 33 to prevent unformed pills from falling into the discharge barrel 22.

[0039] When the pills are taken out after being formed, the driving device is first controlled to stop driving the drum 2 to rotate, and the drum cover 4 is removed after the drum 2 stops rotating. After the drum cover 4 is removed, the lower end of the push rod 31 will lose support, and the entire stirring and discharging assembly 3 will slide downward under the action of gravity until the stirring paddle 32 abuts against the inner bottom wall of the barrel body 21. In addition, the retaining cylinder 33 will be retracted into the discharging cylinder 22 during this process, and then the driving device is controlled to drive the drum 2 to continue rotating. When the drum 2 continues to rotate, the stirring paddle 32 rotates to the lower side and continues to rotate to cooperate with the barrel body 2 1 The inner bottom wall lifts the pills. When the stirring paddle 32 rotates to the point where the outer end is higher than the inner end, the pills on the stirring paddle 32 will slide toward the inner end under the action of gravity, that is, slide toward the side of the retaining cylinder 33. When it slides to the retaining cylinder 33, due to the loss of the support of the inner bottom wall of the barrel body 21, the pills on the stirring paddle 32 will fall into the retaining cylinder 33 under the action of gravity. The pills entering the retaining cylinder 33 will be discharged into the discharge cylinder 22. Finally, the pills will be discharged from the discharge cylinder 22. A collection container can be placed under the discharge cylinder 22 to collect the pills. It can be seen that when workers take out pills from the pill rolling device, they only need to remove the cylinder cover 4. The subsequent pill rolling device will automatically discharge the pills. It can be seen that the drug taking operation is simple and convenient, saving time and effort, with high work efficiency, and is conducive to market promotion and use.

[0040] In this embodiment, the side of the retaining cylinder 33 has a limiting protrusion 331, and the inner wall of the discharge cylinder 22 is provided with a limiting slide groove 221 that matches the limiting protrusion 331 and extends along the axial direction of the discharge cylinder 22, and the limiting protrusion 331 is slidably assembled in the limiting slide groove 221. The limiting protrusion 331 cooperates with the limiting slide groove 221 to form a rotation limit between the retaining cylinder 33 and the discharge cylinder 22, thereby preventing the retaining cylinder 33 from rotating axially relative to the discharge cylinder 22.

[0041] Furthermore, the limiting protrusion 331 is in a long strip shape matching the limiting chute 221. When the stirring paddle 32 abuts against the inner bottom wall of the barrel 21 under the action of gravity, the upper end of the limiting protrusion 331 will be flush with the upper end of the limiting chute 221. This arrangement can prevent the upper part of the limiting chute 221 from being vacant, thereby preventing the powder from entering the limiting chute 221.

[0042] Furthermore, there are six limiting protrusions 331 around the circumference of the retaining cylinder 33, and the number of limiting slots 221 is consistent with and corresponds to the number of limiting protrusions 331. Such a configuration can ensure the connection quality between the retaining cylinder 33 and the discharge cylinder 22, so that the torque can be stably transmitted between the two.

[0043] In this embodiment, there are three stirring paddles 32 , and the three stirring paddles 32 are radially distributed around the retaining cylinder 33 . Such an arrangement can increase the turning frequency of the barrel body 21 during the ball rolling process.

[0044] Furthermore, the three stirring paddles 32 are evenly distributed around the axis of the baffle cylinder 33, and the inner ends of the three stirring paddles 32 are fixedly connected to each other. Such an arrangement allows a stirring paddle 32 located at the front side in the rotation direction to serve as a baffle for the rear stirring paddle 32 when discharging materials. In this way, when the rear stirring paddle 32 is discharging medicine, the pills that roll over the baffle cylinder 33 due to inertia will be blocked by the front stirring paddle 32, so that the pills are within the range of the baffle cylinder 33, so as to avoid the pills on the stirring paddle 32 sliding inward and sliding over the baffle cylinder 33 due to inertia, thereby achieving stable medicine discharge.

[0045] Furthermore, the upper end of the push rod 31 is fixedly connected to the mutually fixed joints of the plurality of stirring paddles 32. Such an arrangement allows the push rod 31 to rotate around its own axis when the retaining cylinder 33 rotates, so as to reduce the moving stroke of the lower end of the push rod 31, thereby reducing the wear between the push rod 31 and the cylinder cover 4.

[0046] Furthermore, the lower end of the push rod 31 is rotatably connected with a ball 311. Such an arrangement can reduce the friction coefficient between the push rod 31 and the cylinder cover 4, so as to further reduce wear and tear, while saving energy consumption.

[0047] In this embodiment, the frame 1 includes a mounting plate 11, a bearing 12 and a bracket (not shown in the figure), a bearing hole 111 is opened inside the mounting plate 11, the outer ring of the bearing 12 is fixedly connected to the inner wall of the bearing hole 111, and the inner ring of the bearing 12 is fixedly connected to the outer wall of the discharge barrel 22. Such an arrangement can realize a rotation connection between the drum 2 and the frame 1.

[0048] In this embodiment, the driving device includes a driving motor (not shown in the figure), a driving pulley (not shown in the figure), a driven pulley 5 and a transmission belt (not shown in the figure), the driving motor is arranged on the frame 1, the driving pulley is coaxially fixed to the output shaft of the driving motor, the driven pulley 5 is coaxially fixed to the discharge cylinder 22, and the transmission belt is connected between the driving pulley and the driven pulley 5. When the driving motor is working, it drives the driving pulley to rotate, and the rotation of the driving pulley can drive the driven pulley 5 to rotate through the driven pulley 5, so that the drum 2 can be driven to rotate.

[0049] In summary, the present invention discloses a ball rolling device, which can turn the raw materials over during the process of preparing pills to allow the raw materials to fully contact each other, thereby improving the pill forming speed to a certain extent. In addition, after the pills are formed, the ball rolling device can be simply operated to realize automatic medicine discharge, and the medicine taking operation is simple and convenient, saving time and labor, with high work efficiency, which is conducive to market promotion and use.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
