Description

Technical Field

[0001] The present invention relates to the technical field of screening equipment for capsule production, in particular to a vibration screening device for finished capsule production products. Background Art

[0002] Capsules refer to solid preparations made by filling drugs into hollow hard capsules or sealing them in elastic soft capsules. During the production process of capsules, some capsules may have quality problems due to machine precision, production temperature, and operational errors. Screening devices are usually used to screen them.

[0003] There are many existing technologies for screening devices, such as:

[0004] Chinese patent publication number CN205056470U discloses a capsule sorting workbench, including a sorting box, a guide plate, a hopper, an air duct expansion port, a duct, a dust collector, a discharge port, a guide channel, a sorting table, an unqualified capsule holding box, a conveyor belt, a rotating shaft, a control device, a rotating shaft motor, a qualified capsule placement box and a vibration screening device. The vibration screening device includes a vibration screen holding box, a drop hole, a reciprocating motion track, a through groove, a slider, a connecting rod, an eccentric wheel and a motor. This utility model adds a hollow capsule sorting device and a deformed capsule sorting device to the front end of a traditional capsule sorting table. This patent sorts out dust, medicine powder, unqualified filling capsules, and severely deformed capsules in advance, thereby greatly reducing the workload of manual capsule screening and greatly improving work efficiency.

[0005] However, there are still some problems in actual use:

[0006] 1. During the use of traditional screening devices, when there are quality problems with the capsule, such as obvious damage to the capsule or loose connection of the capsule, the powder in the capsule will overflow. When the powder overflows in batches, these fine particles will spread inside the screening device like dust. With the airflow or movement of the capsule, they will adhere to the surface of the screen. The particles will stick to each other to form flocs and get stuck at the entrance of the screen mesh instead of simply falling through the mesh, forming an "initial blockage point" and resulting in low screening efficiency.

[0007] 2. The capsules in the sieve chamber box tend to accumulate due to gravity in a static state, forming a multi-layered "capsule cluster" - the hollow capsule shells in the lower layer will be pressed by the upper layer capsules. For the suction shell port with constant negative pressure suction, it is difficult to contact the negative pressure area of ​​the suction device, resulting in the suction device "not being able to suck" or "not sucking thoroughly", resulting in batch contamination due to leakage of drug powder during subsequent storage and transportation, and affecting the efficacy of the drug due to the loss of active ingredients, affecting the production quality of the product.

[0008] In view of this, we propose a vibration screening device for finished capsule production products. Summary of the Invention

An eccentric wheel is provided at the end of the secondary gear rod, and the eccentric wheel is always in contact with the top of the pressure plate. When the eccentric end of the eccentric wheel rotates to be in contact with the top of the pressure plate, the rubber ball provided at the bottom of the pressure plate hits the screen.

[0019] As a further improvement of this technical solution, a cylinder is provided on the side of the bracket away from the discharge port, and a push plate is provided on the piston rod at the end of the cylinder. When the cylinder drives the push plate to move up in the vertical direction, one side of the sieve chamber box is subjected to force and is inclined.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the vibrating screening device for finished capsule production, the movable plate moves horizontally inside the sieve cavity box. Since the cross-section of the movable plate is an arc-shaped hollow, the capsules below the sieve cavity box are flipped upward as the movable plate moves horizontally. During the movement of the capsule position, the residual powder in the gap between the capsules above the sieve cavity box falls onto the screen surface for screening, thereby completely removing the residual powder between the capsules.

[0022] 2. In the vibrating screening device for finished capsule production, the roller is driven to rotate on the inner wall of the sieve chamber box during the movement of the movable plate. When the roller rotates, it drives the main gear to rotate coaxially. When the main gear rotates, it drives the sub-gear rod to engage and rotate. At this time, the eccentric wheel at the end of the sub-gear rod rotates. When the eccentric wheel rotates to the eccentric end, it squeezes the top of the pressure plate. When the pressure plate is under pressure, the sliding rod fixed on the top of the pressure plate slides on the inner wall of the cylinder and stretches the compression spring. When the pressure plate moves downward in the vertical direction, it drives the rubber ball to reciprocate and impact the surface of the screen, thereby avoiding blockage of the screen and improving the screening efficiency of the powder.

[0023] 3. In the vibrating screening device for finished capsule production, the capsules inside the sieve box are vibrated by a vibration motor, and the powder inside the broken capsules is separated from the capsules, which greatly reduces their gravity. The suction shell port connected to the end of the corrugated hose is sucked by controlling the negative pressure device, and a negative pressure state is present near the suction shell port, so that the powder in the sieve box is sucked. When the movable plate moves horizontally to drive the bottom of the sieve box, the movable plate "turns over" the bottom capsules upward, exposing the broken capsules that were originally covered. Due to the continuous vibration of the vibration motor and the turning of the capsules by the movable plate, the weight of the broken capsules can be quickly reduced to half or less of that of normal capsules. The capsules with quality problems are sucked into the negative pressure device through the air expansion sleeve and collected due to their light weight, which quickly screens the capsules and reduces the labor intensity of the operators.

[0040] The purpose of this embodiment is to provide a vibrating screening device for finished capsule production. Figures 1-8As shown, it includes a bracket 100, a sieve box 101 is provided above the bracket 100, a sieve box 101 is provided inside the sieve box 101, a collecting box 109 is provided below the sieve, and the collecting box 109 is used to collect the leaked medicine powder. The bracket 100 and the sieve box 101 are connected by an elastic member 102, and an extension plate 103 is provided on the side wall of the sieve box 101. A vibration motor 104 is provided between the extension plates 103. When the vibration motor 104 is in operation, it drives the sieve box 101 to vibrate. When the vibration motor 104 is in operation, it continuously vibrates the broken capsule so that the medicine powder inside the capsule overflows to the outside. The weight of the broken capsule is lower than that of the normal capsule. A discharge port 106 is provided at the end of the sieve box 101, and an electric discharge port 106 is provided on one side of the discharge port A movable telescopic rod 107 is provided, and a baffle 108 is provided at the end of the electric telescopic rod 107. A sealing cover 200 is provided above the sieve cavity box 101, and a feed port 201 is provided on one side of the top of the sealing cover 200. A dispersing component 300 is provided inside the sieve cavity box 101, and the dispersing component 300 moves horizontally back and forth inside the sieve cavity box 101. When the dispersing component 300 moves, the accumulated capsules are moved to disperse them. An anti-blocking component 400 is provided inside the dispersing component 300, and the anti-blocking component 400 is used to knock on the screen to make the powder stuck inside the screen fall off. A dust removal component 500 is provided on the side of the sealing cover 200 away from the feed port 201, and the dust removal component 500 cooperates with the dispersing component 300 to collect the separated capsules.

[0041] Taking into account that during the screening process of capsules, if the capsules are piled up for too long, the capsule skin is likely to be adhered by pressure, resulting in damage to the capsule skin and increased production costs, the dispersion component 300 includes a rotating motor 301 arranged on one side of the sieve cavity box 101, the output shaft of the rotating motor 301 passes through the sieve cavity box 101 and is provided with a screw rod 302 at the end, a moving block 303 is provided on the surface of the screw rod 302, a base plate is provided on the top of the moving block 303, a moving plate 304 is provided under the moving block 303, and the bottom of the moving plate 304 is in contact with the surface of the sieve mesh. The output end of the rotating motor 301 is controlled to drive the screw rod 302 to rotate, and when the screw rod 302 rotates, it drives the moving block 303 to move horizontally on its surface, and when the moving block 303 moves, it drives the moving plate 304 to move, and when the moving plate 304 moves, it moves the capsules under the sieve cavity box 101 to make the capsules roll, thereby avoiding squeezing and adhering to each other when the capsules are in a static state for a long time, thereby reducing production costs.

[0042] During the screening process of capsules, when some capsules are broken or loose due to the looseness of the capsule shell, the medicine powder inside the capsules is mixed between the capsules. In order to facilitate the rapid removal of the medicine powder, the bracket 100 and the sieve cavity box 101 are connected by an elastic member 102. The side wall of the sieve cavity box 101 is provided with an extension plate 103. A vibration motor 104 is provided between the extension plates 103. When the vibration motor 104 is in operation, it drives the sieve cavity box 101 to vibrate. The cross section of the movable plate 304 is an arc-shaped hollow shape. When the movable plate 304 moves horizontally, the capsules rise and fall in accordance with the surface of the movable plate 304. When the capsules are screened, by starting the vibration motor 104, When the vibration motor 104 is operating, it drives the sieve cavity box 101 to shake on the surface of the elastic member 102 through transmission operation. At this time, the capsules inside the sieve cavity box 101 are always in a vibrating state, so that the powder scattered between the capsules falls through the sieve to be collected in the collection box 109. When the capsules inside the sieve cavity box 101 vibrate, the movable plate 304 moves horizontally inside the sieve cavity box 101. Since the cross-section of the movable plate 304 is an arc-shaped hollow shape, the capsules below the sieve cavity box 101 are flipped upwards as the movable plate 304 moves horizontally, so that the powder remaining between the upper capsules falls through the sieve, thereby completely removing the powder remaining between the capsules.

[0043] In the process of screening the powder between the capsules, when there is a lot of powder, it is easy to clog the sieve holes of the sieve. Therefore, a column 405 is provided at the bottom of the movable plate 304, and a slide rod 406 is provided on the inner wall of the column 405 for sliding. A pressure plate 408 is provided at the bottom of the slide rod 406, and a rubber ball 409 is provided at the bottom of the pressure plate 408. The rubber balls 409 are arranged in an array. When the sieve is clogged, the pressure plate 408 is moved downward in the vertical direction by toggling the pressure plate 408. When the pressure plate 408 moves, the slide rod 406 slides on the inner wall of the column 405 and stretches the compression spring 407. The rubber ball 409 at the bottom of the pressure plate 408 hits the surface of the sieve to make the powder fall, thereby clearing the clogged sieve holes.

[0044] When the powder is collected through the screen, it is easy to clog the screen holes, affecting the screening efficiency of the powder. Therefore, the anti-blocking component 400 includes a fixed frame arranged at the bottom of the movable plate 304, a roller 401 is provided in the fixed frame, a main gear 402 is provided at the bottom of the roller 401 through the fixed frame, a rubber sleeve is provided on the surface of the roller 401, and the roller 401 is fitted with the inner wall of the sieve chamber box 101. A sub-gear rod 403 is provided on one side of the main gear 402, and the sub-gear rod (403) rotates at the end of the bearing seat, and the bearing seat is fixed under the movable plate (304). An eccentric wheel 404 is provided at the end of the sub-gear rod 403, and the eccentric wheel 404 is always fitted with the top of the pressing plate 408. When the eccentric end of the eccentric wheel 404 rotates to fit with the top of the pressing plate 408, the rubber ball 402 provided at the bottom of the pressing plate 408 is pressed against the bottom of the pressing plate 408. 09 impacts the screen, and the capsule is stirred at the bottom of the screen by horizontal movement of the movable plate 304. During the movement of the movable plate 304, the roller 401 is driven to rotate on the inner wall of the sieve chamber box 101. When the roller 401 rotates, it drives the main gear 402 to rotate coaxially. When the main gear 402 rotates, it drives the sub-gear rod 403 to engage and rotate. At this time, the eccentric wheel 404 at the end of the sub-gear rod 403 rotates. When the eccentric wheel 404 rotates to the eccentric end, it squeezes the top of the pressure plate 408. When the pressure plate 408 is under pressure, the sliding rod 406 fixed on its top slides on the inner wall of the pressure plate 408 and stretches the compression spring 407. When the pressure plate 408 moves downward in the vertical direction, it drives the rubber ball 409 to reciprocately impact the surface of the screen, thereby avoiding blockage of the screen and improving the screening efficiency of the medicine powder.

[0045] Taking into account that some capsules have quality problems during the production process, such as broken capsules or loose capsules, which cause the powder in the capsules to overflow, during the screening process, operators are required to remove the capsule shells with quality problems, which results in high labor intensity. Therefore, the impurity removal component 500 includes a negative pressure device 501 provided on the top of the sealing cover 200, and the exhaust port at the end of the negative pressure device 501 is provided with a corrugated hose 502, the corrugated hose 502 passes through the sealing cover 200 and is provided with a shell suction port 503 at the end, and the shell suction port 503 is fixed on the surface of the substrate, the negative pressure device 501 is used to exhaust the powder inside the sieve chamber box 101, and the wind pressure threshold of the negative pressure device 501 is used to suck capsules that are less than half of the normal capsule weight, and a three-way tap is provided between the corrugated hose 502 and the shell suction port 503. The bottom of the three-point head is connected to a suction shell port 503, and the bottom of the suction shell port 503 is provided with an air expansion sleeve 504. The inner wall of the air expansion sleeve 504 is arc-shaped, and the capsule inside the sieve cavity box 101 is vibrated by the vibration motor 104, and the medicine powder inside the broken capsule is separated from the capsule, which greatly reduces its gravity. At this time, the suction shell port 503 connected to the end of the corrugated hose 502 is sucked by controlling the negative pressure device 501, and a negative pressure state is present near the suction shell port 503. When the movable plate 304 moves horizontally to drive the bottom of the sieve cavity box 101, the movable plate 304 "rolls" the bottom capsule upward, exposing the broken capsule that was originally covered. The broken capsule is collected into the negative pressure device 501 due to its light weight, thereby accurately removing the broken capsule and reducing the labor intensity of the operator.

[0046] In order to facilitate the rapid collection of the screened capsules, a cylinder 105 is provided on the side of the bracket 100 away from the discharge port 106, and a push plate is provided on the piston rod at the end of the cylinder 105. When the cylinder 105 drives the push plate to move up in the vertical direction, one side of the sieve chamber box 101 is subjected to force and is inclined. When the capsule screening is completed, the piston rod at the end of the cylinder 105 is controlled to drive the push plate to move in the vertical direction, and the push plate pushes the bottom side of the sieve chamber box 101, and the electric telescopic rod 107 is controlled to drive the baffle 108 to move up in the vertical direction, so that the capsules are collected through the discharge port 106 under the action of gravity, thereby facilitating the rapid collection of the screened capsules.

[0047] When in use, the output end of the rotating motor 301 is controlled to drive the screw rod 302 to rotate. When the screw rod 302 rotates, the moving block 303 moves horizontally on its surface. When the moving block 303 moves, the moving plate 304 moves. When the moving plate 304 moves, the capsules under the sieve cavity box 101 are moved, so that the capsules roll between each other, thereby preventing the capsules from being squeezed and adhered in a static state for a long time, thereby reducing production costs.

[0048] The movable plate 304 moves horizontally inside the sieve cavity box 101. Since the movable plate 304 has an arc-shaped hollow cross-section, the capsules below the sieve cavity box 101 are flipped upward as the movable plate 304 moves horizontally. During the movement of the capsule position, the residual powder in the gap between the capsules above the sieve cavity box 101 falls onto the screen surface for sieving, thereby completely removing the residual powder between the capsules.

[0049] The capsule is stirred at the bottom of the screen by the horizontal movement of the movable plate 304. During the movement of the movable plate 304, the roller 401 is driven to rotate on the inner wall of the sieve chamber box 101. When the roller 401 rotates, it drives the main gear 402 to rotate coaxially. When the main gear 402 rotates, it drives the sub-gear rod 403 to mesh and rotate. The sub-gear rod 403 rotates below the movable plate 304. At this time, the eccentric wheel 404 at the end of the sub-gear rod 403 rotates. When the eccentric wheel 404 rotates to the eccentric end, it squeezes the top of the pressure plate 408. When the pressure plate 408 is subjected to pressure, the sliding rod 406 fixed on the top of the pressure plate 408 slides on the inner wall of the cylinder 405 and stretches the compression spring 407. When the pressure plate 408 moves downward in the vertical direction, it drives the rubber ball 409 to reciprocate and impact the surface of the screen, thereby avoiding blockage of the screen and improving the screening efficiency of the medicine powder.

[0050] The capsules inside the sieve chamber box 101 are vibrated by the vibration motor 104, and the powder inside the damaged capsules is separated from the capsules, which greatly reduces their gravity. The suction port 503 connected to the end of the corrugated hose 502 is sucked by the negative pressure device 501, and a negative pressure state is formed near the suction port 503. When the movable plate 304 moves horizontally to turn the capsules, the capsules with quality problems are sucked into the suction port 503 through the air expansion sleeve 504 due to their light weight, and are then collected inside the negative pressure device 501, thereby reducing the labor intensity of the operators.

[0051] When the capsule screening is completed, the piston rod at the end of the control cylinder 105 drives the push plate to move in the vertical direction, and the push plate pushes the bottom side of the sieve chamber box 101, and the electric telescopic rod 107 is controlled to drive the baffle 108 to move up in the vertical direction, so that the capsules are collected through the discharge port 106 under the action of gravity, thereby facilitating the rapid collection of the screened capsules.
