Description

Technical Field

[0001] The utility model relates to the field of capsule polishing and sorting, in particular to a capsule polishing and sorting machine. Background Art

[0002] Capsule polishing and sorting machine is a key equipment in the pharmaceutical industry used to improve the appearance quality of capsules and sort out unqualified capsules.

[0003] Chinese utility model patent publication number "CN203598237U" discloses a vertical capsule sorting and polishing machine and hard capsule filling system, comprising: a capsule hopper with a space for holding finished capsules, the capsule hopper being connected to the discharge port of the capsule filling machine; a polishing device, the hopper port of which is connected to the lower side of the polishing device; a support frame, the support frame being provided with a motor for driving the polishing device, the polishing device being mounted upright above the support frame; a powder suction device, which is connected to the side of the polishing device along the longitudinal direction of the polishing device and is circumferentially spaced from the capsule hopper; and a sorting device, comprising multiple sorting devices, which are connected to the upper side of the polishing device and mounted to the support frame via a sorting device bracket. The vertical capsule sorting and polishing machine of this utility model performs polishing and sorting operations for finished capsules, occupies a small area, and facilitates fully automatic aseptic operation of the hard capsule filling system.

[0004] However, upon completion of sorting, the capsules in this vertical capsule sorting and polishing machine undergo parabolic motion due to the tilted exits of the various sorting devices. This irregular motion causes some capsules to fly outside the collection device, resulting in wasted capsules. Furthermore, most existing vertical capsule sorting and polishing machines utilize traditional universal wheels for movement, lacking an effective fixing mechanism. This significantly increases the machine's random movement, potentially compromising its stability and operational safety. Utility Model Content

[0005] The purpose of the utility model is to provide a capsule polishing and sorting machine to solve the above problems existing in the prior art.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a capsule polishing and sorting machine, including a base, a feed hopper, a polishing device, and a sorting device.

[0007] By adopting the above technical solution: by connecting the collection feed port of the collection device with the sorting discharge port of the sorting device, the collection device can quickly and accurately collect the sorted qualified capsules, and the collection slope can buffer the fallen capsules and gradually gather them to the collection discharge port, thereby avoiding the scattering and loss of capsules and improving the convenience of collecting capsules.

[0008] The above-mentioned capsule polishing and sorting machine can be further configured as follows: the collecting device is provided with a connecting rod, one end of the connecting rod is fixedly connected to the collecting device, and the other end is provided with a connecting end adapted to the outer periphery of the support frame, the connecting end is divided into a limiter and a fixing part, the limiter and the fixing part are detachably connected by bolts, and the connecting rod stabilizes the collecting device on the outside of the sorting outlet through the fixing part and the limiter.

[0009] By adopting the above technical solution: the connecting rod is fastened to the support frame through the limiter and the fixing member at one end of the connecting rod, and the other end of the connecting rod is fixed to the collecting device. The connecting rod provides a good fixed support capability for the collecting device, so that the collecting device will not shake obviously during the use of the machine, and the fixed position of the limiter and the fixing member can be adjusted according to actual needs, thereby adjusting the relative position of the collecting device.

[0010] The above-mentioned capsule polishing and sorting machine can be further configured as follows: the support frame includes an adjusting rod for adjusting the height of the sorting device and a locking mechanism for locking the adjusting rod, the locking mechanism includes a handle and a locking sleeve, the locking sleeve is sleeved on the outer periphery of the adjusting rod and can be against the support frame, the locking sleeve is provided with a plurality of locking holes, and the handle is inserted into the locking hole.

[0011] By adopting the above technical solution, a handle is inserted into a plurality of locking holes on a locking sleeve. The locking sleeve is also mounted on the outer periphery of the connection between the support frame and the adjustment rod. The adjustment rod can be tightened or loosened by rotating the handle. When the rotating handle is loosened, the adjustment rod can be extended or retracted to change the position of the sorting device. When the adjustment is completed, the exposed length of the adjustment rod can be maintained stable by rotating the rotating handle in the opposite direction, thereby improving the adaptability of the sorting device to the height.

[0012] The above-mentioned capsule polishing and sorting machine can be further configured as follows: the base is provided with several movable fixing devices, the movable fixing devices include universal wheels for all-round movement and fixing devices for fixing and integrated with the universal wheels, the fixing devices include a fixed column, a telescopic rod that is against the fixed column, and an adjusting gear provided on the telescopic rod, and the fixing device raises and lowers the height of the fixed column by rotating the adjusting gear so that the universal wheel is lifted off or contacts the ground.

[0013] By adopting the above technical solution: compared with the traditional universal wheel fixing method, a mobile fixing device set up on the same day as the universal wheel is adopted, which improves the reusability of the device. When the machine needs to be kept in a specified position, the adjusting gear is rotated to adjust the exposed length of the fixing column so that the universal wheel is separated from the ground, allowing the machine to stay in the specified position; when the machine needs to be moved, the adjusting gear is rotated in the opposite direction to shorten the exposed length of the fixing column, so that the universal wheel contacts the ground again and the machine can be pushed to move, which greatly improves the convenience of moving and fixing the machine.

[0015] By adopting the above technical solution: by providing multiple sorting devices, when capsules move from the polishing device to the polishing discharge pipe and enter the diversion pipe, the diversion pipe diverts the capsules to each sorting device, reducing the load on each sorting device. At the same time, the curved structure of the diversion pipe prevents the capsules from hitting the diversion point, causing the body cap to separate and break. A waste collection box is provided above the sorting device using a spring buckle, making it easier to collect waste capsules. The curved block at the top of the waste collection box prevents waste capsules from rebounding into the discharge hopper. At the same time, the discharge hopper below is connected to the collection device and has a certain slope to enable the capsules to slide into the collection device and facilitate the sorting device to screen the capsules.

[0016] The above-mentioned capsule polishing and sorting machine can be further configured as follows: the base is provided with a fixed seat for fixing the polishing device, the polishing device is vertically installed on the fixed seat through a clamp, the polishing device includes a motor, a polishing cylinder, a brush coupling sleeve, a brush rod, a brush, and a spring.

[0017] By adopting the above technical solution: the polishing device is fixed to the base through a fixing seat and the motor is placed in the fixing seat. The rotation of the motor drives the bearing to rotate. Since the brush coupling sleeve is linked with the motor through the clamping connection of the groove body and the screw, when the motor rotates, the brush rod rotates accordingly, thereby driving the brush to rotate to polish the surface of the capsule. The spring can effectively prevent the capsule from falling and make it rotate stably along the inner wall of the polishing cylinder and rise to the discharge port.

[0018] The above-mentioned capsule polishing and sorting machine can be further configured as follows: the polishing cylinder is divided into an upper polishing cylinder and a lower polishing cylinder, the upper polishing cylinder and the lower polishing cylinder are detachably connected by a clamp, and a sealing cover is provided at the end of the upper polishing cylinder away from the lower polishing cylinder, and the sealing cover and the upper polishing cylinder are detachably connected by a clamp, and a sealing ring is provided in the clamp, the polishing feed pipe is provided at the lower side of the lower polishing cylinder, and the polishing discharge pipe is provided at the upper side of the upper polishing cylinder.

[0019] By adopting the above technical solution: splitting the polishing cylinder into an upper polishing cylinder and a lower polishing cylinder, the overall length of the polishing cylinder can be changed according to the actual length of the brush coupling sleeve, so that the vertical height of the polishing discharge pipe in the upper polishing cylinder is consistent with the vertical height of the brush at the top of the brush coupling sleeve, and the capsules will not accumulate in the polishing cylinder due to the height difference between the brush and the polishing discharge pipe.

DETAILED DESCRIPTION

[0035] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 11The capsule polishing and sorting machine shown includes a base 1, a feed hopper 2, a polishing device 3, and a sorting device 4. A support frame 11 is provided on the base 1, and the sorting device 4 is placed on the support frame 11. The hopper port of the feed hopper 2 is connected to the lower side of the polishing device 3, and the sorting device 4 is connected to the upper side of the polishing device 3. A powder suction tube 31 is provided on the outer periphery of the polishing device 3, and a collecting device 5 is provided at the sorting discharge port 45 of the sorting device 4. The collecting feed port 52 of the collecting device 5 is clamped with the sorting discharge port 45, and a collecting discharge port 53 is provided at the end of the collecting device 5 away from the collecting feed port 52. Collecting slopes 54 are provided on both sides of the collecting discharge port 53, and the collecting discharge port 53 is arranged vertically to the collecting feed port 52. By connecting the collection feed port 52 of the collection device 5 with the sorting discharge port 45 of the sorting device 4, the collection device 5 can quickly and accurately collect the sorted qualified capsules through the collection discharge port 53. At the same time, the collection slope 54 can buffer the fallen capsules and gradually gather them to the collection discharge port 53, thereby avoiding the scattering and loss of capsules and improving the convenience of collecting capsules.

[0037] like Figures 1 to 4 The collecting device 5 shown is provided with a connecting rod 51, one end of which is fixedly connected to the collecting device 5, and the other end of which is provided with a connecting end 511 adapted to the outer periphery of the support frame 11. The connecting end 511 is divided into a limiting member 512 and a fixing member 513. The limiting member 512 and the fixing member 513 are detachably connected by bolts. The connecting rod 51 stabilizes the collecting device 5 outside the sorting outlet 45 through the fixing member 513 and the limiting member 512. The limiting member 512 and the fixing member 513 at one end of the connecting rod 51 fasten the connecting rod 51 to the support frame 11, while the other end of the connecting rod 51 is fixed to the collecting device 5. The connecting rod 51 provides good fixed support for the collecting device 5, so that the collecting device 5 does not shake significantly during use of the machine. The fixed position of the limiting member 512 and the fixing member 513 can be adjusted according to actual needs, thereby adjusting the relative position of the collecting device 5.

[0038] like Figures 1 to 3 The support frame 11 shown includes an adjustment rod 111 for adjusting the height of the sorting device 4 and a locking mechanism 12 for locking the adjustment rod 111. The locking mechanism 12 includes a handle 121 and a locking sleeve 122. The locking sleeve 122 is sleeved on the outer periphery of the adjustment rod 111 and can be abutted against the support frame 11. The locking sleeve 122 is provided with a plurality of locking holes 123, and the handle 121 is inserted into the locking holes 123. The locking sleeve 122 is sleeved on the outer periphery of the connection between the support frame 11 and the adjustment rod 111. The adjustment rod 111 can be tightened or loosened by rotating the handle 121. When the rotary handle 121 is loosened, the adjustment rod 111 can be extended or retracted to change the position of the sorting device 4. When the adjustment is completed, the exposed length of the adjustment rod 111 can be kept stable by rotating the rotary handle 121 in the opposite direction, thereby improving the adaptability to the height of the sorting device 4.

[0039] like Figure 1 、 Figure 2 、 Figure 10 、 Figure 11 The base 1 shown is provided with a plurality of movable fixing devices 13, which include universal wheels 131 for all-round movement and fixing devices 14 for fixing and integrally provided with the universal wheels 131. The fixing devices 14 include a fixing column 141, a telescopic rod 142 abutting against the fixing column 141, and an adjusting gear 143 provided on the telescopic rod 142. The fixing device 14 raises and lowers the fixing column 141 by rotating the adjusting gear 143 so that the universal wheels 131 are lifted off or contact the ground. Compared with the traditional fixing method of the universal wheel 131, the mobile fixing device 13 set on the same day as the universal wheel 131 improves the reusability of the device. When the machine needs to be kept at a specified position, the adjusting gear 143 is rotated to adjust the exposed length of the fixing column 141 so that the universal wheel 131 is separated from the ground, allowing the machine to stay at the specified position; when the machine needs to be moved, the adjusting gear 143 is rotated in the opposite direction to shorten the exposed length of the fixing column 141, so that the universal wheel 131 contacts the ground again and the machine can be pushed to move, which greatly improves the convenience of moving and fixing the machine.

[0040] like Figures 1 to 3 、 Figure 5 There are several sorting devices 4 shown. The polishing discharge pipe is connected to the feed ports of multiple sorting devices 4 through a diverter pipe 41. The diverter part of the diverter pipe 41 is an arc-shaped structure. A waste collection box 42 is provided above the sorting device 4. The waste collection box 42 is detachably connected to the waste collection box 42 through a spring buckle 43. An arc-shaped block 421 is provided on the top of the waste collection box 42. A discharge hopper 44 is provided below the sorting device 4. The sorting device 4 screens capsules through the discharge hopper 44 and is connected to the collecting device 5. When the capsule moves from the polishing device 3 to the polishing discharge pipe and enters the diversion pipe 41, the diversion pipe 41 diverts the capsule to each sorting device 4, reducing the load of each sorting device 4. At the same time, the arc-shaped structure of the diversion pipe 41 prevents the body cap from being separated and damaged due to the capsule hitting the diversion point, and a waste collection box 42 is set above the sorting device 4 through a spring buckle 43, so that the collection of waste capsules is faster, and the arc-shaped block 421 on the top of the waste collection box 42 prevents the waste capsules from bouncing back into the discharge hopper 44.

[0041] like Figures 6 to 8The base 1 shown is provided with a fixed seat 15 for fixing the polishing device 3. The polishing device 3 is vertically mounted on the fixed seat 15 through a clamp 152. The polishing device 3 includes a motor 32, a polishing cylinder 33, a brush coupling sleeve 34, a brush rod 35, a brush 36, and a spring 37. The brush coupling sleeve 34 is arranged below the brush rod 35. The inner side of the brush 36 is fixedly connected to the outer peripheral surface of the brush coupling sleeve 34 and spirally wound around the outer periphery of the brush coupling sleeve 34. The spring 37 is placed in the polishing cylinder 33. A bearing 151 is provided in the fixed seat 15. The motor 32 is arranged in the fixed seat 15. The transmission end of the motor 32 is rotatably connected to the bearing 151. The transmission end of the motor 32 is provided with a screw 321. A groove body 341 is provided at one end of the brush coupling sleeve 34. The brush coupling sleeve 34 is linked with the motor 32 by snapping the screw 321 into the groove body 341. The polishing device 3 is fixed to the base 1 through the fixing seat 15 and the motor 32 is placed in the fixing seat 15. The rotation of the motor 32 drives the bearing 151 to rotate. Since the brush coupling sleeve 34 is connected with the motor 32 through the slot 341 and the screw 321, when the motor 32 rotates, the brush rod 35 rotates accordingly, thereby driving the brush 36 to rotate to polish the surface of the capsule. The spring 37 can effectively prevent the capsule from falling and make it stably rotate along the inner wall of the polishing cylinder 33 and rise to the discharge port.

[0042] The polishing cylinder 33 is divided into an upper polishing cylinder 331 and a lower polishing cylinder 332. The upper polishing cylinder 331 and the lower polishing cylinder 332 are detachably connected by a clamp 152. A sealing cap 334 is provided at the end of the upper polishing cylinder 331 away from the lower polishing tube. The sealing cap 334 is detachably connected to the upper polishing cylinder 331 by a clamp 152. A sealing ring is provided within the clamp 152. The polishing feed pipe is provided at the lower side of the lower polishing cylinder 332, and the polishing discharge pipe is provided at the upper side of the upper polishing cylinder 331. By splitting the polishing cylinder 33 into the upper polishing cylinder 331 and the lower polishing cylinder 332, the overall length of the polishing cylinder 33 can be adjusted according to the actual length of the brush coupling sleeve 34. This ensures that the vertical height of the polishing discharge pipe in the upper polishing cylinder 331 is consistent with the vertical height of the brush 36 at the top of the brush coupling sleeve 34. This prevents capsules from accumulating in the polishing cylinder 33 due to the height difference between the brush 36 and the polishing discharge pipe.

[0043] The polishing cylinder 33 is provided with a plurality of powder suction holes 335. A sealing box 38 is provided on the outside of the polishing cylinder 33 to cover the powder suction holes 335. The sealing box 38 is detachably connected to the outer periphery of the polishing cylinder 33 via a plurality of handwheels 381. The powder suction tube 31 is located on the lower side of the end of the sealing box 38 away from the polishing cylinder 33. The plurality of powder suction holes 335 are provided on the outer wall of the polishing cylinder 33. The sealing box 38 fully covers the powder suction holes 335 via the handwheel 381. By connecting the powder suction holes 335 of the powder suction device to the powder suction tube 31 on the sealing box 38, the powder in the polishing cylinder 33 can be sucked in, keeping the polishing cylinder 33 clean and reducing the impact of powder accumulation on the capsule polishing effect.

[0044] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
