Description

Technical Field

[0001] The present application relates to the technical field of capsule polishing equipment, and in particular to a capsule polishing machine. Background Art

[0002] Capsules are protective shells for drugs. Drugs in capsules are usually powder or granular drugs that are irritating to the esophagus and gastric mucosa. Capsule polishing machines are special polishing equipment for capsules and tablets. They can remove dust on the surface of capsules and tablets and improve the surface finish. They are suitable for the production of various capsules and tablets.

[0003] The Chinese utility model patent with the announcement number CN207171770U discloses a capsule polishing machine, which includes a bracket and a polishing cylinder for cleaning capsules, wherein a rotatable brush for cleaning capsules is arranged in the polishing cylinder. When in use, the electric motor drives the rotating shaft to rotate, and the rotating shaft drives the brush to rotate inward, thereby pushing the capsule downward.

[0004] However, during the polishing process, the contact area between the capsule and the polishing cylinder is small, resulting in insufficient polishing of the capsule. At the same time, the dust generated by polishing adheres to the capsule and is not easy to clean, which ultimately reduces the polishing effect of the capsule. Summary of the invention

[0005] In order to improve the polishing effect of capsules, the present application provides a capsule polishing machine.

[0006] The present application provides a capsule polishing machine, which adopts the following technical solution: A capsule polishing machine, comprising: A polishing cylinder, the top and bottom ends of which are respectively connected to a feed pipe and a discharge pipe, a plurality of groups of polishing grooves are provided on the inner wall of the polishing cylinder, the plurality of groups of polishing grooves are arranged along the axis direction of the polishing cylinder, each group of polishing grooves is arranged around the axis of the polishing cylinder, and the shape of the polishing grooves is the same as that of the capsule; A polishing assembly, including a motor, a connecting tube and a brush rod; A stirring assembly is disposed in the polishing cylinder and is used to blow and stir the dust in the polishing cylinder; A cleaning component is disposed in the polishing cylinder and is used to discharge dust in the polishing cylinder; A discharge assembly, both ends of which are respectively connected to the stirring assembly and the discharge pipe, and is used to discharge the polished capsules; in, The motor is fixedly connected to the polishing cylinder; The connecting cylinder is connected to the output shaft of the motor, and the axis direction is the same as the axis direction of the polishing cylinder, and the connecting cylinder is rotatably connected to the polishing cylinder; The brush rods are provided in multiple groups, and the multiple groups of brush rods correspond to the multiple groups of polishing grooves one by one. The multiple groups of brush rods are arranged along the axial direction of the connecting tube. Each group of brush rods is provided with multiple brush rods, and the multiple brush rods are arranged around the axial direction of the connecting tube. The end of the brush rod away from the connecting tube is arranged in the direction close to the polishing groove, and the brush rod is made of elastic material.

[0007] By adopting the above technical solution, when the capsule mass falls into the bottom end of the polishing cylinder through the feed pipe, the output shaft of the motor transmits power to the connecting cylinder, and the connecting cylinder drives the brush rod to rotate. The brush rod stirs the capsule mass to disperse and pushes all the capsules into the polishing groove. As the connecting cylinder rotates continuously, the brush rod presses against the capsule and applies radial force to the capsule, causing the capsule to rotate. Since the brush rod is made of elastic material, it will deviate during the rotation process. At the same time, the brush rod will also drive the capsule to move up and down. The capsule rubs against the polishing groove, so that the whole body of the capsule can be polished, which makes it easy to improve the polishing effect and polishing quality of the capsule; When the polishing time reaches the set value, the motor reverses, the stirring component drives the connecting cylinder to stop rotating, and starts to blow and stir the dust in the polishing cylinder, making the dust active; then, the cleaning component transmits vibration force to the polishing cylinder, so that the capsule is separated from the polishing groove, and the capsule is vibrated, so that the dust attached to the capsule can be separated from the capsule, and then the internal dust is discharged from the polishing cylinder; finally, the discharge component discharges the polished capsule, thereby further improving the polishing efficiency.

[0008] Optionally, the stirring assembly comprises: The reversing part includes a rotating shaft, a shaft sleeve, a first ratchet set and a second ratchet set; A driving part, two ends of which are respectively connected to the reversing part and the polishing cylinder, and is used to drive the blowing and stirring part to rotate; A blowing and stirring part, which is arranged on the driving part and is used to blow and stir the dust inside the polishing cylinder; in, The rotating shaft is coaxially fixedly connected to the output shaft of the motor and is located above the connecting cylinder; The shaft sleeve is sleeved on the rotating shaft and is rotatably connected to the inner wall of the polishing cylinder; The ratchet assembly 1 includes a ratchet 1, a pawl 1 and a spring 1. The ratchet wheel is coaxially fixed on the rotating shaft; The ratchet 1 is hinged on the inner wall of the shaft sleeve, and the tip of the ratchet 1 abuts against the teeth of the ratchet 1; One end of the spring is fixedly connected to the pawl, and the other end is fixedly connected to the sleeve; The ratchet set 2 includes a ratchet wheel 2, a pawl 2 and a spring 2. The ratchet wheel 2 is coaxially fixed on the rotating shaft, and the direction of the teeth of the ratchet wheel 2 is opposite to the direction of the teeth of the ratchet wheel 1; The second pawl is hinged on the inner wall of the connecting tube, and the tip of the second pawl abuts against the teeth of the second ratchet wheel; One end of the spring 2 is fixedly connected to the pawl 2, and the other end is fixedly connected to the connecting tube.

[0009] By adopting the above technical solution, when the capsule mass falls into the bottom end of the polishing cylinder through the feeding pipe, the motor output shaft drives the rotating shaft to rotate, the rotating shaft drives the ratchet wheel 2 to rotate forward, and drives the ratchet wheel 1 to rotate reversely. At this time, the ratchet wheel 1 cannot be stuck on the ratchet wheel 1, and the shaft sleeve cannot rotate; under the cooperation of the ratchet wheel 2 and the ratchet wheel 2, the rotating shaft drives the connecting cylinder to rotate, and the connecting cylinder drives the brush rod to rotate. The brush rod stirs the capsule mass to disperse and pushes all the capsules into the polishing groove. As the connecting cylinder rotates continuously, the brush rod presses against the capsule and applies radial force to the capsule, so that the capsule is easy to be polished all over. When the polishing time reaches the set value, the motor reverses, the motor output shaft drives the shaft to reverse, and the shaft drives the second ratchet to reverse. At this time, the second pawl cannot be stuck with the second ratchet, and the connecting tube stops rotating. Due to the lack of centrifugal force on the brush rod, the brush rod leaves the polishing groove under the action of elastic force and no longer contacts the capsule. At the same time, the rotating shaft drives the ratchet wheel 1 to rotate forward. With the cooperation of the ratchet wheel 1 and the pawl 1, the rotating shaft drives the sleeve to rotate. The sleeve transmits power to the driving part, and the driving part drives the blowing and stirring part to blow and stir the dust inside the polishing cylinder, thereby helping to blow and stir the dust in the polishing cylinder more comprehensively, avoiding dust accumulation in a certain area, and thus making it easy to improve the efficiency of dust treatment.

[0014] Optionally, a distance is left between the fixing ring and the inner wall of the polishing cylinder, and the cleaning assembly includes: The shocking parts are provided with multiple groups, and the multiple groups of shocking parts are arranged around the axis of the polishing cylinder, and the shocking parts include an extrusion block, a push rod and a knocking rod; An extraction part is arranged in the polishing cylinder and is used to extract dust in the polishing cylinder; in, The extrusion block is located on a side of the fixing ring close to the polishing cylinder; The push rod is slidably arranged on the polishing cylinder, and a compression spring is sleeved on the push rod, and two ends of the compression spring are respectively fixedly connected to the push rod and the polishing cylinder; The knocking rod is rotatably connected to the outer wall of the polishing cylinder through a hinge rod, one end of the knocking rod is hinged to the push rod, and the other end is arranged in a direction close to the polishing groove.

[0015] By adopting the above technical solution, the shaft sleeve drives the fixed ring to rotate, the fixed ring drives the extrusion block to rotate, the extrusion block squeezes the push rod, the push rod drives the knocking rod to rotate, the knocking rod knocks the polishing cylinder, and under the action of the vibration force, the capsule is separated from the polishing groove; At the same time, the push rod stretches the extrusion spring, and the extrusion spring accumulates elastic force. When the extrusion block turns away from the push rod, the push rod is reset under the elastic force of the extrusion spring, and the fixed ring continues to rotate, so that the knocking rod repeatedly knocks the polishing cylinder, and the capsule vibrates, so that the dust attached to the capsule can be separated from the capsule. At the same time, it can effectively loosen and shake off the dust attached to the inner wall of the polishing cylinder and the polishing groove, so that the dust can easily float in the air, so that the dust loosened by the extraction part in time can be extracted out of the polishing cylinder, which makes it easy to improve the polishing quality.

[0016] Optionally, the extraction unit includes: A dust concentration sensor is fixedly mounted on the inner wall of the polishing cylinder and is used to output a dust concentration signal in the polishing cylinder; An exhaust pipe, connected to the polishing cylinder; An air pump connected in series to the exhaust pipe; The controller is fixed on the polishing cylinder. The dust concentration sensor and the air pump are both electrically connected to the controller. The controller responds to the dust concentration signal output by the dust concentration sensor and is used to control the start and stop of the air pump.

[0017] By adopting the above technical solution, the dust concentration sensor detects the dust concentration in the polishing cylinder and outputs the dust concentration signal in the polishing cylinder to the controller. When the dust concentration reaches the set value, the controller controls the air pump to turn on, and the air pump promptly extracts the dust in the polishing cylinder through the exhaust pipe, which can effectively prevent dust from accumulating in the polishing cylinder and maintain the cleanliness of the polishing cylinder, thereby easily improving the polishing effect and product quality.

[0018] Optionally, a knock hammer is fixedly provided at one end of the knock rod away from the push rod.

[0019] By adopting the above technical solution, the knocking rod can generate a strong impact force when pushed by the push rod. The physical knocking effect can destroy the adhesion state of the dust, making it easier to remove, thereby facilitating further improving the cleaning effect.

In the initial state, the return spring is in a stretched state; The slide plate is fixedly connected to the movable end of the discharge telescopic rod and is slidably arranged on the discharge pipe. The outer periphery of the slide plate abuts against the inner wall of the discharge pipe.

[0021] By adopting the above technical solution, the knocking rod drives the knocking hammer to knock on the polishing cylinder, and the knocking hammer squeezes the airbag ring. Under the continuous knocking of the knocking hammer, the gas in the airbag ring enters the rod cavity of the discharge telescopic rod through the connecting pipe, and the volume of the rod cavity of the discharge telescopic rod increases. The movable end of the discharge telescopic rod drives the slide plate to move, and the slide plate opens the discharge pipe, and the polished capsule gradually leaves the discharge pipe. When the discharge pipe is fully opened, all capsules are detached, at which time the motor stops rotating, the air pump stops pumping air, and under the elastic force of the reset spring, the movable end of the discharge telescopic rod drives the slide plate to move, and the slide plate closes the discharge pipe, thereby realizing automatic discharge and improving the degree of automation of the equipment.

[0022] Optionally, one end of the polishing cylinder close to the discharge pipe is in a constricted shape, and the polishing groove is located at the constricted portion of the polishing cylinder.

[0023] By adopting the above technical solution, the constricted design allows the polishing cylinder to form a certain pressure gradient in this area. When the capsule moves in the polishing cylinder, its speed will be relatively slowed down when it reaches the constricted part, and the contact time with the polishing groove will be increased, thereby enhancing the friction and impact effect between the capsule and the polishing groove, making it easier to more thoroughly remove dust and impurities on its surface, thereby making it easier to improve the polishing quality.

[0024] Optionally, the blowing and stirring parts are provided in a plurality of groups, and the plurality of blowing and stirring parts are arranged around the axis of the fixing ring.

[0025] By adopting the above technical solution and increasing the number of blowing and stirring parts, the blowing and stirring effect is made more comprehensive and in-depth, thereby enhancing the dust cleaning effect.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: By arranging the polishing groove, the motor, the connecting tube and the brush rod, the whole body of the capsule can be polished, so that the polishing effect and polishing quality of the capsule can be easily improved; By providing a reversing part, a driving part and a blowing and stirring part, it is helpful to blow and stir the dust in the polishing cylinder more comprehensively, avoid the accumulation of dust in a certain area, and thus facilitate to improve the efficiency of dust treatment; By providing the shock part and the extraction part, the dust is easily floated in the air, so that the dust loosened by the extraction part can be extracted out of the polishing cylinder in time, thereby facilitating the improvement of the polishing quality; By arranging an air bag ring, a connecting pipe, a discharging telescopic rod and a slide plate, automatic discharging can be realized, thereby improving the automation degree of the equipment.

[0050] Reference Figure 1 and Figure 3 The discharge assembly 5 includes an airbag ring 51, a connecting tube 52, a discharge telescopic rod 53 and a slide plate 54. The airbag ring 51 is fixedly mounted on the outer wall of the polishing cylinder 1 and is located between the striking hammer 414 and the polishing cylinder 1. In the embodiment of the present application, the airbag ring 51 is filled with air and is made of silicone rubber material.

[0051] One end of the connecting tube 52 is connected to the airbag ring 51, and the other end is connected to the rod cavity of the discharging telescopic rod 53. The discharging telescopic rod 53 is fixedly connected to the bracket 11, and a return spring 531 is arranged in the rodless cavity of the discharging telescopic rod 53. The two ends of the return spring 531 are respectively fixedly connected to the fixed end and the movable end of the discharging telescopic rod 53. In the initial state, the return spring 531 is in a stretched state.

[0052] The slide plate 54 is in the shape of a rectangular plate. The slide plate 54 is fixedly connected to the movable end of the discharge telescopic rod 53 and is slidably arranged on the discharge pipe 13. The outer periphery of the slide plate 54 abuts against the inner wall of the discharge pipe 13. The distance between the slide plate 54 and the bottom end of the connecting tube 22 is smaller than the diameter of the capsule.

[0053] When in use, the knocking rod 413 drives the knocking hammer 414 to knock on the polishing cylinder 1, and the knocking hammer 414 squeezes the airbag ring 51. Since the airbag ring 51 is made of silicone rubber material, it is not easy for the airbag ring 51 to quickly recover its deformation. Under the continuous knocking of the knocking hammer 414, the air in the airbag ring 51 enters the rod cavity of the discharge telescopic rod 53 from the connecting tube 52, and the air gradually squeezes the movable end of the discharge telescopic rod 53. The movable end of the discharge telescopic rod 53 drives the slide plate 54 to move, and the slide plate 54 opens the discharge pipe 13, and the polished capsule gradually separates from the discharge pipe 13; When the discharge pipe 13 is fully opened, all capsules are detached. At this time, the motor 21 stops rotating, the air pump 423 stops pumping air, and under the elastic force of the reset spring 531, the movable end of the discharge telescopic rod 53 drives the slide plate 54 to move, and the slide plate 54 closes the discharge pipe 13, thereby realizing automatic discharge, thereby improving the degree of automation of the equipment.

[0054] The implementation principle of a capsule polishing machine in the embodiment of the present application is as follows: a capsule mass is put into the polishing cylinder 1, and the capsule mass falls onto the inclined side wall of the polishing cylinder 1, and the output shaft of the motor 21 drives the rotating shaft 311 to rotate, and the rotating shaft 311 drives the ratchet wheel 1 3131 to reverse, and the shaft sleeve 312 does not rotate; at the same time, the rotating shaft 311 drives the ratchet wheel 2 3141 to rotate forward, and under the cooperation of the ratchet wheel 2 3141 and the ratchet pawl 2 3142, the rotating shaft 311 drives the connecting cylinder 22 to rotate, and the connecting cylinder 22 drives the pressing rod to rotate, and the pressing rod pushes all the capsules into the polishing groove 15, and as the connecting cylinder 22 rotates continuously, the pressing rod drives the capsule to rotate, and the whole body of the capsule is polished; When the polishing time reaches the set value, the motor 21 reverses, the output shaft of the motor 21 drives the rotating shaft 311 to reverse, the rotating shaft 311 drives the second ratchet 3141 to reverse, and the connecting cylinder 22 stops rotating; at the same time, the rotating shaft 311 drives the first ratchet 3131 to rotate forward, under the cooperation of the first ratchet 3131 and the first ratchet 3132, the rotating shaft 311 drives the fixing ring 321 to rotate, the fixing ring 321 drives the driving gear 331 to rotate, the gear ring 322 drives the driving gear 331 to rotate, and the driving gear 331 drives the fan 334 to rotate, blow and stir the dust in the polishing cylinder 1 to prevent the dust from accumulating in the polishing cylinder 1; At the same time, the fixed ring 321 drives the extrusion block 411 to rotate, the extrusion block 411 squeezes the push rod 412 to move, the push rod 412 drives the knocking rod 413 to rotate, the knocking rod 413 drives the knocking hammer 414 to knock the polishing cylinder 1, and the capsule is shaken off the polishing groove 15. The fixed ring 321 continues to rotate, so that the knocking rod 413 repeatedly knocks the polishing cylinder 1, the capsule vibrates, and the dust attached to the capsule can be separated from the capsule; The dust concentration sensor 421 detects the dust concentration in the polishing cylinder 1 and outputs the dust concentration signal in the polishing cylinder 1 to the controller 424. When the dust concentration reaches the set value, the controller 424 controls the air pump 423 to turn on. The air pump 423 promptly extracts the dust in the polishing cylinder 1 from the exhaust pipe 422, which can effectively prevent the dust from accumulating in the polishing cylinder 1. The knocking rod 413 drives the knocking hammer 414 to knock on the polishing cylinder 1, and the knocking hammer 414 squeezes the airbag ring 51. Under the continuous knocking of the knocking hammer 414, the air in the airbag ring 51 enters the rod cavity of the discharge telescopic rod 53 from the connecting tube 52, and the air gradually squeezes the movable end of the discharge telescopic rod 53. The movable end of the discharge telescopic rod 53 drives the slide plate 54 to move, and the slide plate 54 opens the discharge pipe 13. The polished capsules gradually separate from the discharge pipe 13, thereby realizing automatic discharge, thereby improving the polishing effect of the capsules.
