Description

Technical Field

[0001] This utility model relates to the field of counting equipment technology, and in particular to a rotary tablet counting device. Background Technology

[0002] Tablets, also known as pharmaceutical tablets, are a common drug dosage form. They are solid preparations that are formed by compressing a drug and excipients into tablets or irregularly shaped tablets. The main characteristics of tablets are stable quality, accurate dosage, and stable physicochemical properties.

[0003] Pills are typically packaged, stored, and transported using medicine bottles. To ensure a consistent number of pills in each bottle, a pill counting device is needed for filling. For example, Chinese Patent Publication No. CN212125763U discloses a quantitative feeding device for granular materials, comprising: a frame; a feeding hopper, which is inclinedly mounted on the frame and has a feeding through-hole at its bottom, located on the side of the bottom of the hopper that is higher than the other side; a feeding device, positioned above the feeding hopper to add material to the side of the hopper that is lowest in height; and a counting turntable, rotatably mounted inside the feeding hopper, close to the bottom of the hopper, with several counting holes on the turntable. The counting turntable is driven to rotate by a feeding drive device, and the counting holes pass over the feeding through-hole when the turntable rotates. This invention can accurately dispense a certain number of pills, offering higher efficiency, lower cost, and smaller size.

[0004] In actual operation, the feeding hopper drives the counting turntable to rotate through the drive device at the bottom to count and feed the tablets. However, the counting turntable and the feeding hopper cannot be disassembled. Firstly, it is inconvenient to replace and maintain after long-term use. Secondly, different counting turntables have different numbers of counting holes, so it is not possible to replace the counting turntables of different specifications, which affects the scope of application and the efficiency of drug loading, resulting in poor practicality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the counting turntable and the feeding hopper cannot be disassembled, and to propose a turntable tablet counting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a rotary tablet counting device, including a frame, with a conveying device and several counting devices on the top of the frame. Medicine bottles are placed on the conveying device for conveying and tablet filling is performed through the counting devices.

[0008] The counting device includes a base, and a connecting rod is rotatably connected to the top of the base via a drive device. A turntable is detachably connected to the end of the connecting rod via a fixing component.

[0009] The base is connected to a feeding pipe at the bottom feeding port. The feeding pipe works in conjunction with the turntable. Several adjustment components are provided between the feeding pipe and the top of the frame. The adjustment components are used to adjust the position of the feeding pipe's discharge port.

[0010] Furthermore, the fixing component includes a limiting groove and a limiting block. The top end of the connecting rod is provided with at least one limiting groove along the axis. The turntable is clearance-fitted with the table surface of the base, and the limiting block is provided at the through hole located at the midpoint of the turntable. The limiting block is slidably connected to the limiting groove.

[0011] The turntable has a circumferential array of several sets of counting holes on its end face, and each of the counting holes is set in a manner corresponding to the feeding port.

[0012] Furthermore, a stop rod is slidably connected to the top of the connecting rod via a compression spring. One end of the stop rod extends to the periphery of the connecting rod and abuts against the turntable. A clearance groove is provided on the periphery of the stop rod, and an unlocking rod is provided in the clearance groove.

[0013] Furthermore, the unlocking rod is slidably connected to the connecting rod, and its top extends to the periphery of the connecting rod and is provided with a pressing part. The bottom of the unlocking rod is slidably connected to the relief groove and is provided with a guide groove. The side of the relief groove is provided with a guide part, and the guide part is slidably connected to the guide groove.

[0014] Furthermore, the adjustment assembly includes a first adjustment rod, a second adjustment rod, and a fixing member. The fixing member has through holes formed on its two ends and top, and its side edges connect to the through holes to form deformation grooves. The first adjustment rod is fixedly connected to the side of the frame, and the first adjustment rod and the second adjustment rod are slidably connected in the through holes located on the top and side, respectively.

[0015] Furthermore, the two ends of the fixing member are threaded with screws, one end of the screw passes through the deformation groove and is threaded with a nut.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A rotary tablet counting device includes a frame 1, a conveying device 2 and several counting devices 3 are provided on the top of the frame 1, a medicine bottle is placed on the conveying device 2 for conveying, and the tablets are filled through the counting devices 3.

[0024] The counting device 3 includes a base 31, the top of which is rotatably connected to a connecting rod 32 via a driving device 4, and the end of the connecting rod 32 is detachably connected to a turntable 6 via a fixing component 5.

[0025] The base 31 is connected to the discharge pipe 34 at the bottom discharge port 33. The discharge pipe 34 is used in conjunction with the turntable 6. Several adjustment components 7 are provided between the discharge pipe 34 and the top of the frame 1. The adjustment components 7 are used to adjust the position of the discharge port of the discharge pipe 34.

[0026] It should be added that the conveying device 2 is a conveyor belt connected to the top of the frame 1 by a motor. The conveyor belt and a pair of baffles 11 convey the medicine bottles. Cylinders are fixedly connected to both sides of the top of the frame 1, and stop plates are fixedly connected to the shaft end of the cylinders. The stop plates are used to stop the medicine bottles and release the medicine bottles after they are full. Of course, a sensor is also provided on the top of the frame 1. The sensor and the cylinder are electrically connected to the control unit.

[0027] Furthermore, the fixing component 5 includes a limiting groove 51 and a limiting block. The top end of the connecting rod 32 is provided with at least one limiting groove 51 along the axis. The turntable 6 is in clearance fit with the table surface of the base 31, and the limiting block is provided at the through hole located at the midpoint of the turntable 6. The limiting block is slidably connected to the limiting groove 51.

[0028] The turntable 6 has a circumferential array of several sets of counting holes 61 on its end face, and each of the counting holes 61 is set in correspondence with the feed port 33.

[0029] It should be added that the top of the base 31 is circular, and one side of it is inclined towards the conveying device 2. The turntable 6 is adapted to the top of the base 31. The driving device 4 includes a motor, which is fixedly connected to the bottom of the base 31, and its shaft end is fixedly connected to the tail end of the connecting rod 32.

[0030] In specific operation, a certain amount of pills are poured into the interior of the base 31, that is, the end face of the turntable 6. Due to the clearance fit between the turntable 6 and the table surface of the base 31, the pills placed in the counting hole rotate with the turntable 6 when it rotates.

[0031] It should be noted that the limiting groove 51 does not completely penetrate the connecting rod 32. The limiting groove 51 is opened to an appropriate length to ensure that the turntable 6 rotates synchronously with the connecting rod 32 and also has a clearance fit with the base 31.

[0032] Furthermore, the counting hole 61 passes through the turntable 6, and the counting hole is adapted to the diameter and height of the tablet to prevent two or more tablets from being stored in one counting hole 61. When the turntable 6 drives the tablet to rotate to the feeding port 33, the tablet is released from the counting hole 61 under its own gravity. Of course, the tablet will be weighed by a weighing device after filling.

[0033] Furthermore, the top of the connecting rod 32 is slidably connected to a stop rod 53 via a compression spring 52. One end of the stop rod 53 extends to the periphery of the connecting rod 32 and abuts against the turntable 6. A clearance groove 54 is provided on the periphery of the stop rod 53, and an unlocking rod 55 is provided in the clearance groove 54.

[0034] More specifically, the unlocking rod 55 is slidably connected to the connecting rod 32, and its top extends to the periphery of the connecting rod 32 and is provided with a pressing part. The bottom of the unlocking rod 55 is slidably connected to the relief groove 54 and is provided with a guide groove 551. The side of the relief groove 54 is provided with a guide part 541, and the guide part 541 is slidably connected to the guide groove 551.

[0035] In specific operation, the abutment 53, together with the limiting groove 51, fixes the turntable 6. Pressing the unlocking rod 55 causes it to move inward through the guide groove 551 and the guide part 541. After the abutment 53 disengages from the turntable 6, the turntable 6 can be unlocked.

[0036] In general, the adjustment assembly 7 includes a first adjustment rod 71, a second adjustment rod 72, and a fixing member 73. The fixing member 73 has through holes formed on its two sides and top, and its side is connected to the through holes to form a deformation groove 731. The first adjustment rod 71 is fixedly connected to the side of the frame 1, and the first adjustment rod 71 and the second adjustment rod 72 are slidably connected in the through holes located on the top and side, respectively.

[0037] Finally, the two ends of the fixing member 73 are threaded with screws 74. One end of the screw 74 passes through the deformation groove 731 and is threaded with a nut. A pair of baffles 11 are provided on the top two sides of the frame 1. One baffle 11 is fixedly connected to the frame 1, and the top of the other baffle 11 is fixedly connected to a clamping plate 12. The baffle 11 is fixedly connected to one end of the second adjusting rod 72. The clamping plate 12 is used to fix the feed pipe 34.

[0038] It is worth mentioning that the fixing member 73 is preferably made of a material with deformation capability, such as rubber, silicone, etc. In particular, considering that the height and width of the medicine bottles of different specifications are different, the medicine bottles are guided by adjusting the position of the movable baffle 11 in conjunction with the fixed baffle 11, so that the conveying device 2 can convey the medicine bottles better.

[0039] The distance and height of the movable baffle 11 can be adjusted by the first adjusting rod 71 and the second adjusting rod 72, and the position of the clamping plate 12 can be adjusted at the same time. The end of the clamping plate 12 is provided with an opening groove. A spring clip can be set at the top of the clamping plate 12 at the opening groove, or a straight plate can be threadedly connected by a locking bolt, and the discharge end of the feed pipe 34 can be fixed by closing the opening groove by the straight plate. In addition, the feed pipe 34 is preferably a corrugated pipe, and both ends of the corrugated pipe are provided with rigid extension pipes.

[0040] Specifically, the screw 74, in conjunction with the nut, abuts against the side of the fixing member 73 with the deformation groove 731. Both ends of the fixing member 73 should have slotted holes for the screw 74 to pass through. Then, the fixing member 73 clamps a pair of adjusting rods through the deformation groove 731 when it is deformed under force, thereby achieving the function of height and position adjustment.

[0041] Working method: During operation, the position of the movable baffle 11 is adjusted according to the width and height of the medicine bottle. After the screw 74 is unlocked, the fixed part 73 is slidable. The fixed part 73 can drive the second adjusting rod 72 to adjust the height and distance of the baffle 11. Then the screw 74 is locked to fix the position of the baffle 11 and the clamp 12.

[0042] Then, the motor drives the connecting rod 32 to rotate the turntable 6. When the turntable 6 rotates the tablet to the feeding port 33, the tablet leaves the counting hole 61 under its own gravity and is fed out.

[0043] Finally, press the unlocking lever 55 to drive the abutment 53 inward through the guide groove 551 and the guide part 541. Once the abutment 53 disengages from the turntable 6, the turntable 6 can be unlocked.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
