Description

Technical Field

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

[0002] The capsule polishing machine is a special polishing equipment for capsules and tablets. It can remove dust on the surface of capsules and tablets and improve the surface finish. It is suitable for the production of various capsules and tablets. Since the polishing machine emits a lot of heat when working for a long time, the capsule is easy to deform. Therefore, it is necessary to use a heat dissipation device to cool the polishing machine.

[0003] At present, a general heat dissipation device includes a bracket and a polishing machine body. A rectangular through hole is opened on the side wall of the polishing machine body, and a first heat sink is fixedly connected to the hole wall of the rectangular through hole. A driving motor and an arc-shaped cooling block are fixedly connected to the inner wall of the polishing machine body. A fan blade is fixedly connected to the output end of the driving motor. A water tank is fixedly connected to the upper surface of the bracket. A water pump is fixedly connected to the inner wall of the water tank. A first duct is fixedly connected to the output end of the water pump. Heat is dissipated through the cooperation between the fan blade, the arc-shaped cooling block and the water tank.

[0004] However, since the heat dissipation device is arranged on one side of the polishing machine body, the heat dissipation effect is only locally exerted, and the heat dissipation area is limited, thereby resulting in reduced heat dissipation efficiency. Summary of the invention

[0005] In order to improve the heat dissipation efficiency, the present application provides a heat dissipation device for a capsule polishing machine.

[0006] The present application provides a heat dissipation device for a capsule polishing machine, which adopts the following technical solution:

[0007] A heat dissipation device for a capsule polishing machine, comprising:

[0008] Base;

[0009] A polishing cylinder is arranged on the base, wherein the upper end of the polishing cylinder is connected to a feed pipe, and the lower end of the polishing cylinder is connected to a discharge pipe;

[0010] A polishing assembly, comprising a spiral plate 1, a brush and a rotating part, wherein the spiral plate 1 is rotatably connected to the polishing cylinder and is located in the polishing cylinder; a plurality of the brushes are provided, and the plurality of brushes are evenly arranged along the spiral axis of the spiral plate 1, and the brushes are installed on the spiral plate 1; the rotating part is provided in the polishing cylinder and is used to drive the spiral plate 1 to rotate;

[0011] The heat dissipation component includes a second spiral plate, a heat dissipation part, and a control part. A plurality of ventilation holes are formed in the first spiral plate, and the plurality of ventilation holes are evenly arranged along the spiral axis of the first spiral plate. The second spiral plate is located on the side of the first spiral plate away from the feed pipe and is rotatably connected to the polishing cylinder. A heat conduction channel is formed between the first spiral plate and the second spiral plate.

[0012] There are multiple groups of the heat dissipation parts, and the multiple groups of heat dissipation parts are evenly arranged along the spiral axis of the first spiral plate and correspond to the multiple ventilation holes one by one. Both ends of the heat dissipation part are connected to the first spiral plate and the second spiral plate respectively. The heat dissipation part is used to open the channel between the ventilation hole and the outside. The control part is arranged on the polishing cylinder and is used to discharge the heat inside the polishing cylinder.

[0013] The supplementary component includes a detection part, a driving part, and a heat removal part. The detection part is arranged inside the polishing cylinder and is used to detect the temperature inside the polishing cylinder. Both the driving part and the heat removal part are arranged on the polishing cylinder. The driving part is used to drive the heat removal part to further cool the polishing cylinder.

[0014] By adopting the above technical solution, the capsule enters the polishing cylinder through the feed pipe. The rotating part drives the first spiral plate to rotate, and the first spiral plate drives the brush to rotate. Through the rotational movement of the brush, the capsule is driven to move in a circular spiral along the inner wall of the polishing cylinder, so that the capsule advances along the spiral spring. Under the continuous friction with the brush and the inner wall of the polishing cylinder, the outer surface of the capsule shell is polished.

[0015] Since the capsule advances along the spiral spring, the moving path can be divided into multiple segments, and the multiple segments of the path correspond to the positions of the multiple groups of heat dissipation parts. When the capsule is polished on the advancing path, the capsule turns away from the previous path.

[0016] Since heat is generated by the friction between the capsule and the inner wall of the polishing cylinder, when the capsule turns away from the previous path, the corresponding heat dissipation part opens the ventilation hole in the previous path, so that the channel connecting the inside of the polishing cylinder and the outside is opened. The control part discharges the heat inside the polishing cylinder in time through the heat conduction channel.

[0017] When the heat inside the polishing cylinder is still very high, the detection part detects the temperature inside the polishing cylinder and transmits the temperature signal to the driving part. The driving part drives the heat removal part to further cool the outer wall of the polishing cylinder, ensuring that the polishing process is always carried out within a suitable temperature range, so that the capsule is not easily deformed, thereby facilitating the improvement of the heat dissipation efficiency and further facilitating the improvement of the production quality.

[0018] In addition, while the heat dissipation part removes heat, the control part can take out the powder generated by polishing together, thereby facilitating the maintenance of the cleanliness inside the polishing cylinder and further facilitating the reduction of the cleaning difficulty.

[0019] Optionally, the heat dissipation unit includes:

[0020] A closing plate is slidably connected to the spiral plate, and the sliding direction is the axial direction of the ventilation hole;

[0021] A connecting spring is inserted into the ventilation hole, one end of the connecting spring is fixedly connected to the closing plate, and the other end is fixedly connected to the second spiral plate. In the initial state, the connecting spring is in a stretched state;

[0022] A connecting plate, fixedly connected to a side of the closing plate away from the connecting spring and arranged parallel to the spiral plate, wherein the connecting plate is fixedly connected to the brush;

[0023] There are two rotating plates, which are rotatably connected to two ends of the closing plate respectively;

[0024] Among them, a bellows is provided at the connection between the rotating plate and the closing plate, and a support spring is fixed inside the bellows. In the initial state, the support spring is in a compressed state; two elastic strips are fixed on one side of the connecting plate close to the spiral plate, and the elastic strips are hollow inside and connected to the bellows.

[0025] By adopting the above technical solution, when a large number of capsules are put into the polishing cylinder, the capsules fall on the brush, and under the action of gravity, the connecting plate is squeezed to move, the connecting plate drives the closing plate to move, the closing plate squeezes the connecting spring, the compression amount of the connecting spring increases, the connecting spring accumulates elastic force, and the closing plate blocks the ventilation hole;

[0026] At the same time, the closing plate drives the elastic strip to move, and the closing plate cooperates with the spiral plate to squeeze the elastic strip, so that the internal volume of the elastic strip decreases. Since the elastic strip is connected to the bellows, the internal volume of the bellows increases, the elongation of the support spring increases, and the support spring accumulates elastic force. The bellows drives the rotating plate to rotate, and the rotating plate and the connecting plate remain parallel, so that the capsule cannot fall from the side of the rotating plate into the space formed by the connecting plate and the spiral plate.

[0027] When the capsule is polished and transferred to the next path for polishing, the capsule is separated from the brush in the previous path, and under the elastic force of the connecting spring, the connecting spring drives the closing plate to move, and the closing plate moves in a direction away from the spiral plate 1, and the closing plate opens the ventilation hole;

[0028] At the same time, the closing plate drives the elastic strip to move, and the elastic strip returns to its original state. Under the action of negative pressure, the bellows returns to its original state. Under the elastic force of the supporting spring, the bellows drives the rotating plate to rotate to its initial position, so that the polishing cylinder section of the previous path is connected to the heat conduction channel, so that the control unit can easily discharge the heat out of the polishing cylinder through the heat conduction channel, thereby improving the heat dissipation efficiency of the polishing device.

[0031] The induction block 2 is provided with a plurality of induction blocks 1, and the plurality of induction blocks 1 correspond to the plurality of induction blocks 2 one by one. The induction block 2 is fixedly connected to the closing plate through a fixing rod and is arranged opposite to the induction block 1. The induction block 2 is located in the connecting spring;

[0032] A controller, fixedly connected to the polishing cylinder and electrically connected to the second induction block;

[0033] An exhaust pipe is connected to the polishing cylinder, and the exhaust pipe is located on the heat conduction channel;

[0034] An air pump, which is connected in series to the exhaust pipe and is electrically connected to the controller;

[0035] When the first sensing block contacts the second sensing block, the second sensing block outputs a contact signal, and the controller responds to the contact signal output by the second sensing block and controls the vacuum pump to stop working;

[0036] When the first induction block is separated from the second induction block, the second induction block outputs a disconnection signal, and the controller responds to the disconnection signal output by the second induction block and controls the vacuum pump to start working.

[0037] By adopting the above technical solution, under the action of gravity, a large number of capsules squeeze the connecting plate to move, the connecting plate drives the closing plate to move, and through the fixing rod, the closing plate drives the second sensing block to move, and the second sensing block abuts against the first sensing block. At this time, the second sensing block outputs a contact signal to the controller, and the controller responds to the contact signal output by the second sensing block and controls the vacuum pump to stop working;

[0038] When the capsule is polished and transferred to the next path for polishing, the capsule detaches from the brush in the previous path, the closing plate moves away from the spiral plate 1, the closing plate opens the ventilation hole, and the bellows drives the rotating plate to rotate to the initial position, so that the polishing cylinder section of the previous path is connected to the heat conduction channel. At this time, the sensor block 2 outputs a disconnect signal to the controller, and the controller responds to the disconnect signal output by the sensor block 2, and controls the vacuum pump to start working. Through the heat conduction channel, the vacuum pump promptly draws hot air out of the polishing cylinder, making it easy to discharge heat in time, thereby improving the heat dissipation efficiency of the polishing device.

[0039] Optionally, the rotating part includes:

[0040] A motor is fixedly mounted on one end of the polishing cylinder;

[0042] Wherein, the spiral plate 1 is spirally arranged around the axial direction of the rotating shaft and is fixedly connected to the rotating shaft; the spiral plate 2 is arranged parallel to the spiral plate 1 and is fixedly connected to the rotating shaft.

[0043] By adopting the above technical solution, the motor drives the shaft to rotate, and the shaft drives spiral plate 1 and spiral plate 2 to rotate simultaneously. The rotational power output by the motor can be directly and losslessly transmitted to the shaft, thereby driving spiral plate 1 to rotate, thereby improving the overall efficiency of the polishing process.

[0044] Optionally, the heat drive unit includes:

[0045] A water storage tank is fixed on the base through a bracket and stores cold water inside, wherein the water storage tank is connected to a water inlet pipe;

[0046] A water collecting tank is fixed on the base through a bracket, the water collecting tank is connected with a drain pipe, and a valve is provided on the drain pipe;

[0047] The cooling pipe is spirally wound on the polishing cylinder, and the two ends are respectively connected with the water storage tank and the water collecting tank.

[0048] By adopting the above technical solution, when the heat inside the polishing cylinder is still very high, cold water flows along the cooling pipe. Since the cooling pipe is spirally wound on the polishing cylinder, the heat exchange area is increased, so that the cooling water can more effectively absorb the heat from the polishing cylinder.

[0049] Optionally, the interior of the rotating shaft is hollow, and the detection unit includes:

[0050] A plurality of elastic blocks are provided, and the plurality of elastic blocks are evenly arranged along the axis direction of the rotating shaft, and the elastic blocks are embedded in the rotating shaft;

[0051] A driving telescopic rod is fixed on the polishing cylinder;

[0052] A connecting tube, one end of which is respectively connected to the plurality of elastic blocks, and the other end of which is connected to the rodless cavity of the driving telescopic rod, wherein the connecting tube is rotationally connected to the driving telescopic rod.

[0053] By adopting the above technical solution, when the heat inside the polishing cylinder is still very high, the gas in the elastic block is heated and its movement is accelerated. The gas flows through the connecting pipe to the rodless cavity of the driving telescopic rod. The gas pushes the movable end of the driving telescopic rod to move, and the movable end of the driving telescopic rod transmits power to the driving part. By setting up a detection part, the heat changes in each path can be monitored in real time, thereby improving the reliability and stability of the polishing cylinder.

[0054] Optionally, the driving unit includes:

[0055] A spur rack first, coaxially fixedly connected to the movable end of the driving telescopic rod;

[0056] Gear 1, meshing with the spur rack 1 and rotatably connected with the polishing cylinder;

[0058] in,

[0059] The pipe section connecting the cooling pipe and the water tank is connected in series with an opening and closing pipe; a gear 2 is coaxially fixedly connected to the end of the connecting shaft away from the gear 1, and the gear 2 is meshed with a spur rack 2, and the spur rack 2 is slidably connected to the base through a connecting rod; a baffle is fixedly provided at one end of the spur rack 2, and the baffle is passed through the opening and closing pipe, and the outer periphery of the baffle abuts against the inner periphery of the opening and closing pipe.

[0060] By adopting the above technical solution, the gas drives the movable end of the telescopic rod to move, the movable end of the telescopic rod drives the spur rack 1 to move, the spur rack 1 drives the gear 1 to rotate, the gear 1 drives the gear 2 to rotate, the gear 2 drives the spur rack 2 to move, the spur rack 2 drives the baffle to move in the direction away from the opening and closing pipe, opens the opening and closing pipe, and allows cooling water to flow into the cooling pipe for heat dissipation;

[0061] On the contrary, when the temperature drops, the gas in the elastic block flows back, driving the movable end of the telescopic rod to reset, driving the movable end of the telescopic rod to drive spur rack one to move, spur rack one drives gear one to rotate, gear one drives gear two to rotate, gear two drives spur rack two to move, spur rack two drives the baffle to move toward the opening and closing pipe, closes the opening and closing pipe, and cuts off the flow of cooling water. Through the intelligent control mechanism, the operating state of the cooling system can be automatically adjusted according to the actual needs of the polishing cylinder, thereby improving energy utilization efficiency.

[0062] Optionally, a collecting box is detachably connected to the base, the top of the collecting box is an open end, and the open end of the collecting box is located below the discharge pipe.

[0063] By adopting the above technical solution, it is ensured that the material discharged from the discharge pipe can fall into the collection box directly and efficiently, reducing the possibility of material splashing, spilling or leaking, making it easy to collect the polished capsules.

Under the action of negative pressure, the bellows 425 returns to its original state. Under the action of the elastic force of the supporting spring, the bellows 425 drives the rotating plate 424 to rotate to the initial position, so that the polishing cylinder 2 section of the previous path is connected to the heat conduction channel. At this time, the sensing block 432 outputs a disconnect signal to the controller 433. The controller 433 responds to the disconnect signal output by the sensing block 432 and controls the vacuum pump 435 to start working. Through the heat conduction channel, the vacuum pump 435 promptly draws hot air out of the polishing cylinder 2, thereby facilitating the timely discharge of heat, thereby improving the heat dissipation efficiency of the polishing device.

The water storage tank 531 is fixedly arranged on the base 1 through a bracket and stores cold water inside. Among them, a water inlet pipe 5311 is communicated with the water storage tank 531. The water collection tank 532 is fixedly arranged on the base 1 through a bracket and is located on one side of the water storage tank 531.

The baffle 526 is arranged on the switch pipe 5331, and the outer periphery of the baffle 526 abuts against the inner periphery of the switch pipe 5331.

[0109] During use, when the heat inside the polishing cylinder 2 is still very high, the air in the elastic block 511 is heated and moves faster. The air flows from the connecting pipe 513 to the rodless cavity of the driving telescopic rod 512. The gas pushes the movable end of the driving telescopic rod 512 to move. The movable end of the driving telescopic rod 512 drives the first straight rack 521 to move. The first straight rack 521 drives the first gear 522 to rotate. The first gear 522 drives the second gear 524 to rotate. The second gear 524 drives the second straight rack 525 to move.

[0110] When the temperature drops, the gas in the elastic block 511 flows back, driving the movable end of the telescopic rod 512 to reset, which drives the movable end of the telescopic rod 512 to drive the spur rack 1 521 to move, which drives the spur rack 1 521 to drive the gear 1 522 to rotate, which drives the gear 1 522 to rotate, which drives the gear 2 524 to rotate, which drives the spur rack 2 525 to move, which drives the baffle 526 to move toward the opening and closing pipe 5331, closes the opening and closing pipe 5331, and cuts off the flow of cooling water. The intelligent control mechanism can automatically adjust the operating state of the cooling system according to the actual needs of the polishing cylinder 2, thereby improving the energy utilization efficiency.

[0111] The implementation principle of the heat dissipation device of a capsule polishing machine in the embodiment of the present application is as follows: a large number of capsules are put into the polishing cylinder 2 from the feed pipe 21, and driven by the motor 331, the rotating shaft 332 drives the spiral plate 1 31 and the spiral plate 2 41 to rotate simultaneously, the spiral plate 1 31 drives the brush 32 to rotate, and the brush 32 drives the capsule to make a circular spiral motion along the wall of the polishing cylinder 2, and the capsule and the inner wall of the polishing cylinder 2 rotate and rub to perform polishing;

[0112] During the polishing process, the closing plate 421 blocks the ventilation hole 311. When the capsule is polished and transferred to the next path for polishing, the connecting spring 422 drives the closing plate 421 to move under the elastic force of the connecting spring 422. The closing plate 421 moves in a direction away from the spiral plate 31, and the closing plate 421 opens the ventilation hole 311. At the same time, the closing plate 421 drives the elastic strip 4231 to move. Under the elastic force of the supporting spring, the bellows 425 drives the rotating plate 424 to rotate to the initial position, so that the polishing cylinder 2 section of the previous path is connected with the heat conduction channel. At this time, the controller 433 controls the exhaust pump 435 to timely extract the hot air out of the polishing cylinder 2 and discharge the heat in time.

[0113] When the heat inside the polishing cylinder 2 is still very high, the air in the elastic block 511 is heated and moves faster, and the air enters the rodless cavity of the driving telescopic rod 512, and pushes the movable end of the driving telescopic rod 512 to move. Under the transmission action of the gear and the spur rack, the spur rack 525 drives the baffle 526 to move away from the opening and closing tube 5331, opening the opening and closing tube 5331, allowing cooling water to flow into the cooling tube 533 for heat dissipation, thereby further facilitating the improvement of heat dissipation efficiency and thus improving production quality.
