A defective tablet separation device

Abstract

This utility model discloses a defective tablet separation device, including a base. Support legs are fixedly connected to the front and rear ends of the left side of the top of the base. A vibration mechanism is provided on the right side of the top of the base. A separation platform is rotatably connected to the middle position of the two support legs. A material distribution bin is opened inside the upper surface of the separation platform. This utility model utilizes a first rotating blade located on the right side of the top of the separation platform. When a tablet to be separated in the feed inlet comes into contact with the first rotating blade while moving on the sieve plate, it can push the first rotating blade to rotate clockwise. At this time, the first rotating blade can slow down the movement speed of the tablet on the sieve plate. Simultaneously, the rotation of the first rotating blade can drive the first gear to rotate.

The fourth gear can then drive the second rotating blade at the top to rotate counterclockwise, thereby effectively agitating the tablet.

Description

Technical Field

[0001] This utility model relates to the field of tablet separation technology, specifically a defective tablet separation device. Background Technology

[0002] The defective tablet separation device is a production line equipment used in the pharmaceutical or related industries. It is primarily used to automatically identify and reject tablets that are damaged or have dimensional deviations that do not meet quality standards. Defective tablets are separated into a waste channel by a mechanical sorting mechanism, while qualified tablets continue into the packaging process. This device significantly improves the efficiency of quality control in pharmaceutical production, reduces manual intervention, and ensures the safety and consistency of the final product.

[0003] A defective tablet separation device disclosed in Chinese Patent Publication No. CN222625307U uses a push-pull rod to drive two U-shaped fixed frames to slide horizontally along two limiting grooves. The push-pull rod moves the U-shaped fixed frames horizontally inside the separation frame, and drives the bottom of the anti-blocking scraper to scrape the top of the separation plate. However, the defective tablet separation device has certain limitations. The drug tablets cannot stay on the upper surface of the separation device for a sufficient amount of time, resulting in poor separation effect. Some defective drug tablets will still be mixed inside the drug tablets, affecting the overall separation quality of the drug tablets. Utility Model Content

[0004] The purpose of this invention is to provide a defective tablet separation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a defective tablet separation device, comprising a base, with support legs fixedly connected to the front and rear ends of the left side of the top of the base, a vibration mechanism provided on the right side of the top of the base, a separation platform rotatably connected to the middle position of the two support legs, a material distribution bin inside the upper surface of the separation platform, an installation groove provided on the top of the material distribution bin, a sieve plate slidably connected inside the installation groove, and a feed inlet fixedly connected to the front end of the right side of the upper surface of the separation platform, and further comprising a rotating mechanism and a positioning mechanism, wherein the rotating mechanism is used to slow down the movement speed of the drug tablets on the separation platform, and the positioning mechanism is used to limit the sieve plate inside the separation platform.

[0006] Preferably, the vibration mechanism includes a fixed frame fixed to the right side of the upper surface of the base, a motor fixed to the rear end inside the fixed frame, and a toggle block installed on the output shaft end of the motor.

[0007] Preferably, the rotating mechanism includes an isolation chamber fixedly connected to the center of the material distribution chamber, a lubrication pipe fixedly connected to the right side of the front end of the material distribution chamber, a first gear rotatably connected to the right side of the isolation chamber, a second gear rotatably connected to the left side of the first gear, a third gear rotatably connected to the left side of the second gear, and a fourth gear rotatably connected to the left side of the third gear. A cross groove is formed at the center of the upper surface of the first gear, a first rotating blade is provided at the top of the first gear, a cross rod that engages with the cross groove is fixedly connected to the center of the lower surface of the first rotating blade, and a second rotating blade is provided at the top of the fourth gear.

[0008] Preferably, the cross rod and the cross groove are magnetically attracted, and through slots are provided on both sides of the inside of the sieve plate for the cross rod to pass through. The connection method between the fourth gear and the second rotating blade is the same as the connection method between the first gear and the first rotating blade.

[0009] Preferably, the positioning mechanism includes slots on the left and right sides of the rear end of the sieve plate, a movable groove on the outer side of the slot, a movable block slidably connected inside the movable groove, a spring fixed to the lower surface of the movable block, a positioning rod sliding in the slot fixed to the inner side of the movable block, positioning holes for insertion into the positioning rod on the left and right sides of the lower surface of the mounting groove, an empty groove in the middle of the rear end of the separation platform, an electromagnet fixed to the center of the lower surface of the empty groove, a base plate slidably connected inside the empty groove, and insertion rods fixed to the left and right sides of the lower surface of the base plate.

[0010] Preferably, the positions of the insertion rod, slot, positioning rod, and positioning hole correspond to each other.

[0011] Preferably, all electrical equipment inside the separation device is started and controlled by an external remote control.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This defective tablet separation device features a first rotating blade on the right side of the top of the separation platform. When a tablet to be separated in the feed inlet comes into contact with the first rotating blade while moving on the sieve plate, it can push the first rotating blade to rotate clockwise. At this time, the first rotating blade can slow down the movement speed of the tablet on the sieve plate. Simultaneously, the rotation of the first rotating blade can drive the first gear to rotate. The first gear can then drive the fourth gear to rotate through the second and third gears. The fourth gear can then drive the second rotating blade at the top to rotate counterclockwise, thereby effectively agitating the tablets, ensuring the tablets remain on the sieve plate for a sufficient time, ensuring that defective tablets are fully separated by the sieve plate, and improving the efficiency of the separation device.

[0014] 2. This defective tablet separation device features slots on the sieve plate. When the sieve plate is inserted into the mounting groove inside the separation table, and a rod inside the separation table is inserted into the slot on the sieve plate, the rod pushes a positioning rod inside the slot into the positioning hole on the mounting groove, thus ensuring stable installation of the sieve plate on the upper surface of the separation table. When the sieve plate needs replacement or cleaning, the first rotating blade and cross rod are removed from the top of the sieve plate, and the electromagnet inside the separation table is energized. The electromagnet generates a repulsive force that lifts the bottom plate, allowing the bottom rod of the bottom plate to be pulled out of the slot on the sieve plate. Simultaneously, the positioning rod inside the slot can be pulled out of the positioning hole on the separation table, removing the restriction on the sieve plate. The sieve plate can then be quickly removed from the separation table. The operation is simple and convenient, and the modular design improves the ease of cleaning and maintenance of the separation device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides two technical solutions:

[0024] Example 1: A defective tablet separation device includes a base 1. Support legs 101 are fixedly connected to the front and rear ends of the left side of the top of the base 1. A vibration mechanism 2 is provided on the right side of the top of the base 1. A separation platform 3 is rotatably connected to the middle position of the two support legs 101. A material distribution bin 301 is opened inside the upper surface of the separation platform 3. An installation groove 302 is provided on the top of the material distribution bin 301. A sieve plate 4 is slidably connected inside the installation groove 302. A feed inlet 8 is fixedly connected to the front end of the right side of the upper surface of the separation platform 3. The device also includes a rotating mechanism 5 and a positioning mechanism 7. The rotating mechanism 5 is used to slow down the movement speed of the tablets on the separation platform 3, and the positioning mechanism 7 is used to limit the sieve plate 4 inside the separation platform 3.

[0025] The vibration mechanism 2 includes a fixed frame 201 fixed to the right side of the upper surface of the base 1. A motor 202 is fixed to the rear end inside the fixed frame 201. A toggle block 203 is installed at the output shaft end of the motor 202. When the motor 202 is started, it can drive the toggle block 203 to rotate. At this time, the toggle block 203 can repeatedly push the right side of the separation table 3 to move up and down, thereby accelerating the screening of defective tablets on the sieve plate 4.

[0026] The rotating mechanism 5 includes an isolation chamber 304 fixedly connected to the center of the material distribution chamber 301. A lubrication pipe 305 is fixedly connected to the right side of the front end of the material distribution chamber 301. A first gear 501 is rotatably connected to the right side of the isolation chamber 304. A second gear 502 is rotatably connected to the left side of the first gear 501. A third gear 503 is rotatably connected to the left side of the second gear 502. A fourth gear 504 is rotatably connected to the left side of the third gear 503. A cross groove 505 is formed at the center of the upper surface of the first gear 501. A first rotating blade 6 is provided at the top of the first gear 501. A cross rod 601, which engages with the cross groove 505, is fixedly connected to the center of the lower surface of the first rotating blade 6. A second rotating blade 602 is provided at the top of the fourth gear 504. The rotation of the first rotating blade 6 can drive the second gear 502, the third gear 503, and the fourth gear 504 to rotate through the first gear 501. At the same time, the fourth gear 504 can drive the second rotating blade 602 at the top to rotate in the opposite direction and slow down the movement speed of the drug tablets at the top of the sieve plate 4. Lubricating oil can be injected into the gears inside the distribution bin 301 through the lubrication pipe 305.

[0027] The cross rod 601 and the cross groove 505 are magnetically attracted. The two sides inside the sieve plate 4 are provided with through grooves for the cross rod 601 to pass through. The connection method between the fourth gear 504 and the second rotating blade 602 is the same as the connection method between the first gear 501 and the first rotating blade 6. When the cross rod 601 on the first rotating blade 6 passes through the sieve plate 4 and inserts into the cross groove 505 at the top of the first gear 501, the installation of the first rotating blade 6 at the top of the first gear 501 can be completed.

[0028] All electrical equipment inside the separation unit is activated and controlled by an external remote control.

[0029] Example 2 differs from Example 1 mainly in that:

[0030] A defective tablet separation device includes a base 1, with support legs 101 fixedly connected to the front and rear ends of the left side of the top of the base 1. A vibration mechanism 2 is provided on the right side of the top of the base 1. A separation platform 3 is rotatably connected to the middle position of the two support legs 101. A material distribution bin 301 is opened inside the upper surface of the separation platform 3. An installation groove 302 is provided on the top of the material distribution bin 301. A sieve plate 4 is slidably connected inside the installation groove 302. A feed inlet 8 is fixedly connected to the front end of the right side of the upper surface of the separation platform 3. The device also includes a rotating mechanism 5 and a positioning mechanism 7. The rotating mechanism 5 is used to slow down the movement speed of the tablets on the separation platform 3, and the positioning mechanism 7 is used to limit the sieve plate 4 inside the separation platform 3.

[0031] The vibration mechanism 2 includes a fixed frame 201 fixed to the right side of the upper surface of the base 1. A motor 202 is fixed to the rear end inside the fixed frame 201. A toggle block 203 is installed on the output shaft end of the motor 202.

[0032] The rotating mechanism 5 includes an isolation chamber 304 fixedly connected to the center of the material distribution chamber 301. A lubrication pipe 305 is fixedly connected to the right side of the front end of the material distribution chamber 301. A first gear 501 is rotatably connected to the right side of the isolation chamber 304. A second gear 502 is rotatably connected to the left side of the first gear 501. A third gear 503 is rotatably connected to the left side of the second gear 502. A fourth gear 504 is rotatably connected to the left side of the third gear 503. A cross groove 505 is opened at the center of the upper surface of the first gear 501. A first rotating blade 6 is provided at the top of the first gear 501. A cross rod 601 that engages with the cross groove 505 is fixedly connected to the center of the lower surface of the first rotating blade 6. A second rotating blade 602 is provided at the top of the fourth gear 504.

[0033] The cross rod 601 and the cross groove 505 are magnetically attracted. The two sides inside the sieve plate 4 are provided with through grooves for the cross rod 601 to pass through. The connection method between the fourth gear 504 and the second rotating blade 602 is the same as the connection method between the first gear 501 and the first rotating blade 6.

[0034] The positioning mechanism 7 includes slots 401 on the left and right sides of the rear end of the sieve plate 4, with movable grooves 402 on the outer side of the slots 401. Movable blocks 403 are slidably connected inside the movable grooves 402. A spring 404 is fixed to the lower surface of the movable blocks 403. A positioning rod 405, which slides within the slots 401, is fixed to the inner side of the movable blocks 403. Positioning holes 303, which engage with the positioning rods 405, are opened on the left and right sides of the lower surface of the mounting groove 302. A hollow slot 701 is opened in the middle of the rear end of the separating platform 3. An electromagnet 702 is fixed to the center of the lower surface of the hollow slot 701. A base plate 703 is slidably connected inside the hollow slot 701. Insert rods 704 are fixed to the left and right sides of the lower surface of the base plate 703. When the electromagnet 702 is activated, it generates a repulsive force and pushes the base plate 703 to lift. When the bottom plate 703 is lifted, the insertion rod 704 can be lifted and the screen plate 4 can be inserted into the mounting slot 302 on the separation table 3. At this time, the electromagnet 702 is closed, and due to the gravity of the bottom plate 703, the insertion rod 704 can be driven to move downward. The insertion rod 704 is inserted into the slot 401 on the screen plate 4, which can push the positioning rod 405 in the slot 401 to move downward and insert the positioning rod 405 into the positioning hole 303 at the bottom of the mounting slot 302. At the same time, the positioning rod 405 can squeeze the lower spring 404 through the movable block 403. When the electromagnet 702 pushes the bottom plate 703 to lift, the insertion rod 704 is pulled out of the slot 401. Due to the reaction force of the spring 404 being squeezed, the positioning rod 405 can be pulled out from the positioning hole 303 through the movable block 403 and put into the interior of the screen plate 4.

[0035] The positions of the insertion rod 704, slot 401, positioning rod 405, and positioning hole 303 correspond to each other.

[0036] All electrical equipment inside the separation device is started and controlled by an external remote control. In addition, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0037] In this embodiment, the medicine tablets to be separated can be poured into the top of the separation table 3 through the feed inlet 8. At this time, the medicine tablets can move from right to left on the sieve plate 4 at the top of the separation table 3. Simultaneously, the motor 202 in the fixed frame 201 is started, which can drive the agitator block 203 to rotate. At this time, the agitator block 203 repeatedly pushes the separation table 3 to rise and fall, thereby accelerating the separation of defective medicine tablets by the sieve plate 4. When the medicine tablets pass the first rotating blade 6 at the top of the sieve plate 4, the first rotating blade 6 can rotate clockwise and slow down the movement speed of the medicine tablets. At the same time, the first rotating blade 6 can drive the second gear 502, the third gear 503, and the fourth gear 504 to rotate through the first gear 501. At this time, the fourth gear 504 drives the second rotating blade 602 to rotate counterclockwise, which can again agitate the medicine tablets at the top of the sieve plate 4, thereby slowing down the separation rate of the medicine tablets and ensuring effective separation of the medicine tablets.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
