Description

Technical Field

[0001] This utility model relates to the technical field of continuous forced rotation of platform machines in fully automatic capsule production lines, and in particular to a platform machine for forced mold rotation used in fully automatic capsule production lines. Background Technology

[0002] Currently, fully automatic capsule production line platform machines either change the center of gravity of the mold to allow it to rotate freely, or reduce the speed and output to ensure stable rotation of the mold during production. If high-speed production is desired, the mold strips will jump or fly out in a free state, damaging other parts or even injuring workers. Alternatively, the machine may restrict the degree of freedom of the mold strips to rotate, but this would result in a large overall space occupation and excessive weight, placing high demands on the factory facilities of the equipment users. Summary of the Invention

[0003] The present invention provides a platform for forced mold flipping used in a fully automated capsule production line, which at least solves the technical problem of poor mold flipping stability in existing high-speed production lines.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] A platform machine for forced mold flipping used in a fully automated capsule production line flips a mold strip, the mold strip having a base plate portion and a mold body portion distributed along the length direction of the base plate, comprising:

[0006] A rack provides installation space;

[0007] The flipping mechanism is set in the installation space and includes at least two opposing drive shafts that rotate in a direction perpendicular to the xz plane. At least two flipping wheels are fixedly set on the outer circumferential surface of each drive shaft. Each flipping wheel has a main body and multiple flipping plates are arranged along the circumference of the main body. Each flipping plate has a vertical part and a horizontal part. The horizontal part has a bearing surface and the vertical part is provided with a stop block. A groove is formed between the stop block and the bearing surface.

[0008] The feeding mechanism uses a center feeding method to feed the turning mechanism. The feeding mechanism includes a slitting unit and a strip-shifting unit.

[0009] In operation, the two mold strips are first conveyed to the two drive shafts of the flipping mechanism by the slitting unit. Then, the bottom plate of the two mold strips is pushed to move along the y-axis by the strip-shifting unit and locked in one of the slots of the flipping wheel. The two drive shafts are rotated to flip the two mold strips.

[0010] The beneficial effects are as follows: The platform machine for forced mold flipping used in the fully automatic capsule production line provided in this embodiment of the invention limits the mold strip by means of a slot during the flipping process, ensuring that the mold strip will not fly out due to centrifugal force during flipping, thereby solving the technical problem of poor mold flipping stability in existing high-speed production lines.

[0011] Furthermore, the flipping mechanism also includes at least two guard plates, respectively disposed between the two ends of the two drive shafts. Each guard plate has a guard plate body, with limit grooves on both sides of the guard plate body and a limit block at the top of the guard plate body, forming a limit trajectory with the limit grooves. The purpose of this arrangement is that the addition of the guard plates and the limit grooves further limit the movement trajectory of the mold strip during flipping. The limit trajectory formed by the limit block and the limit grooves limits the position of the mold strip from multiple angles, preventing it from shifting position during the flipping process.

[0012] Furthermore, stops are provided on both the left and right sides of the limiting block, forming a limiting space with the limiting trajectory to restrict the movement trajectory of the mold strip. The purpose of this arrangement is that the addition of the stops further forms a limiting space, limiting the position of the mold strip from multiple angles and positions to prevent it from shifting position during the flipping process.

[0013] Furthermore, the flipping mechanism also includes an auxiliary flipping wheel, which is fixedly mounted on the outer wall of the drive shaft and located between the two flipping wheels. The purpose of this arrangement is that the auxiliary flipping wheel improves the stability of the die strip during the flipping process.

[0014] Furthermore, the flipping mechanism also includes a rear support plate and a front support plate arranged opposite each other along the x-axis. A base is mounted on the top of the rear support plate, and at least two servo motors are mounted on the rear side of the base. Each servo motor has a reducer at its output end, and the reducer's output end is connected to one end of a drive shaft via a coupling. The other end of the drive shaft is connected to the front support plate via a bearing. The front support plate has a discharge port at the corresponding position of the flipped mold strip. This arrangement specifically illustrates the drive and discharge components of the flipping mechanism, making its technical solution more complete.

[0015] Furthermore, it also includes a strip feeding mechanism, which includes a pusher that reciprocates along the y-axis, corresponding to the position of the flipped die strip, and pushes the die strip along the y-axis through the discharge port to the next station. The purpose of this arrangement is that the reciprocating pusher discharges the flipped die strip.

[0016] Furthermore, the feeding mechanism also includes a servo motor-driven slide module, which includes a slide that reciprocates along the y-axis. A pusher claw is synchronously connected to the slide via a connecting frame. After the die strip is rotated, it aligns with the discharge port position. The slide of the servo motor-driven slide module drives the pusher claw to move the die strip along the y-axis. The purpose of this arrangement is to use the slide of the servo motor-driven slide module to drive the pusher claw and move the die strip.

[0017] Furthermore, the feeding mechanism also includes a mold conveying unit, which comprises two sets of synchronously moving modules that move in opposite directions along the x-axis, driving the mold strip towards the center of the frame. This arrangement aims to feed the mold strip from both sides of the frame towards its center.

[0018] Furthermore, each set of synchronous movement modules includes two horizontally opposite conveying modules. Each conveying module includes a first and second synchronous pulley at the same horizontal height, a drive pulley, and a synchronous belt. A first and second tensioning pulley are arranged on both sides of the drive pulley. The synchronous belt is sequentially wound around the outer periphery of the drive pulley, the second tensioning pulley, the first synchronous pulley, the second synchronous pulley, and the first tensioning pulley in a counterclockwise direction. The purpose of this arrangement is to enable the two synchronous belts to move synchronously and convey the module strip.

[0019] Furthermore, a drive source with an output end is provided on the outer side of the drive pulley of one of the conveying modules; a synchronous shaft is provided between the first synchronous pulleys of the two conveying modules, causing the two first synchronous pulleys to rotate synchronously; wherein, the output end of the drive source drives the drive pulley to rotate, and the drive pulley drives the first and second synchronous pulleys to rotate via the synchronous belt, conveying the template to the center of the frame. The purpose of this arrangement is to provide a drive source on one side to drive the synchronous belts on both sides to move synchronously.

[0020] Furthermore, the second synchronous pulleys of the two sets of synchronous movement modules are coaxially arranged and rotate synchronously. The purpose of this arrangement is to ensure the consistency of the actions of the two sets of synchronous movement modules.

[0021] Furthermore, the slitting unit includes a drive module and a lifting module. The drive module includes at least two rotating lifting gears; the lifting module includes at least two lifting racks. A central box is mounted on the top of each lifting rack. Positioning blocks are mounted on both the left and right sides of the top of the central box. A pressure cap is mounted on the top of each positioning block, forming a positioning groove between the pressure cap and the positioning block. The lifting gears mesh with the lifting racks, and the rotation of the lifting gears drives the lifting racks to rise or fall, thereby causing the central box to rise or fall. The purpose of this arrangement is to achieve the lifting and lowering of the central box along the z-axis.

[0022] Furthermore, the drive module also includes a drive motor, the output end of which is provided with a rotating shaft, and two lifting gears are disposed on the outer wall of the rotating shaft. The output end of the drive motor drives the lifting gears to rotate through the rotating shaft. The structure of the drive module is specifically exemplified.

[0023] Furthermore, the lifting module also includes an intermediate connecting plate, with an adjustment plate embedded in its center. Hollow seats are provided on both sides of the base of the adjustment plate, and arc-shaped grooves are formed on the outer walls. The lifting rack is inserted into the inner cavity of the hollow seats. A specific example of the lifting module structure is given.

[0024] Furthermore, the shift bar unit is located between the two drive shafts. The shift bar unit includes: one set of driving modules and two sets of driven modules. The driving module includes a shift bar motor and a driving gear disposed at the output end of the shift bar motor. Each driven module includes a bearing housing and a driven gear rotatably connected to the bearing housing, the driven gear meshing with the driving gear. Each shift bar module includes a crank, bearings rotatably connected to the left and right sides of the bottom end of the crank, and a shift bar shaft disposed at the center of the crank, the shift bar shaft being coaxial with and fixedly connected to the driven gear. A specific example of the structure of the shift bar unit is given.

[0025] Furthermore, the shifter unit also includes a linkage module comprising two parallel connecting rods rotatably connected between the two ends of two cranks, forming a parallelogram with the two cranks. This arrangement ensures consistent shifter movement. Attached Figure Description

[0045] This application discloses a forced mold flipping platform machine used in a fully automated capsule production line to flip the mold strip 7. Please refer to [link to relevant documentation]. Figure 7 The mold strip 7 has a base plate portion 71 and a mold body portion 72 distributed along the length direction of the base plate. Please refer to [link / reference]. Figure 1 It includes a frame 1, a tilting mechanism 5, and a feeding mechanism; the frame 1 has installation space; please refer to Figure 2 , Figure 3 and Figure 4 The flipping mechanism 5 is installed within the mounting space and includes at least two opposing drive shafts 55 that rotate perpendicular to the xz plane. At least two flipping wheels 57 are fixedly mounted on the outer circumferential surface of each drive shaft 55. (See also...) Figure 5 Each flipping wheel 57 has a main body 571, and multiple flipping plates 572 are arranged along the circumference of the main body 571. Each flipping plate 572 has a vertical part 573 and a horizontal part 574. The horizontal part 574 has a bearing surface 5741, and the vertical part 573 is provided with a stop block 5731. A groove 575 is formed between the stop block 5731 and the bearing surface 5741. The feeding mechanism feeds the flipping mechanism 5 by center feeding. The feeding mechanism includes a slitting unit 3 and a strip-pulling unit 4.

[0046] In operation, the two mold strips 7 are first conveyed to the two drive shafts 55 of the flipping mechanism 5 by the slitting unit 3. Then, the bottom plate part 71 of the two mold strips 7 is pushed to move along the y-axis direction by the strip-pulling unit 4 and locked in one of the slots 575 of the flipping wheel 57. The two drive shafts 55 are rotated to flip the two mold strips 7.

[0047] It should be noted that, for the convenience of describing the technical features, the length direction of the platform machine is defined as the x-axis direction, the width direction of the platform machine is defined as the y-axis direction, and the height direction of the platform machine is defined as the z-axis direction.

[0048] The fully automatic capsule production line provided in this utility model embodiment uses a platform machine for forced mold flipping. During the flipping process of the mold strip 7, the flipping mechanism 5 limits the mold strip 7 through the slot 575 to ensure that the mold strip 7 will not fly out due to centrifugal force during flipping, thereby solving the technical problem of poor mold flipping stability in existing high-speed production lines.

[0049] Please see Figure 2 and Figure 6 To further limit the movement trajectory of the mold strip 7 during flipping, the flipping mechanism 5 also includes at least two guard plates 59, respectively disposed between the two ends of the two drive shafts 55. Each guard plate has a guard plate body 591, with limiting grooves 592 on both sides of the guard plate body 591. A limiting block 593 is provided at the top of the guard plate body 591, forming a limiting trajectory with the limiting grooves 592. The addition of the guard plates 59 and the limiting grooves 592 further limit the movement trajectory of the mold strip 7 during flipping. The limiting trajectory formed by the limiting block 593 and the limiting grooves 592 limits the position of the mold strip 7 from multiple angles, preventing it from shifting position during flipping.

[0050] Please continue reading Figure 2 To further limit the movement trajectory of the mold strip 7 during flipping, baffles 510 are provided on both the left and right sides of the limiting block 593, forming a limiting space with the limiting trajectory to limit the movement trajectory of the mold strip 7. The addition of baffles 510 further forms a limiting space, limiting the position of the mold strip 7 from multiple angles and positions to prevent it from shifting position during flipping.

[0051] Please continue reading Figure 2 To improve the stability of the die strip 7 during the flipping process, the flipping mechanism 5 also includes an auxiliary flipping wheel 58, which is fixedly mounted on the outer wall of the drive shaft 55 and located between the two flipping wheels 57. The auxiliary flipping wheel 58 enhances the stability of the die strip 7 during the flipping process.

[0052] Please continue reading Figure 2 The driving part and the discharge part of the flipping mechanism 5 are specifically provided as an example to make its technical solution more complete. The flipping mechanism 5 also includes a rear support plate 51 and a front support plate 56 arranged opposite to each other along the x-axis. The top of the rear support plate 51 is provided with a base 52. At least two servo motors 53 are provided on the rear side of the base 52. The output end of the servo motor 53 is provided with a reducer. The output end of the reducer is connected to one end of the drive shaft 55 through a coupling. The other end of the drive shaft 55 is connected to the front support plate 56 through a bearing. The front support plate 56 is provided with a discharge port 561 at the position corresponding to the flipped mold strip 7.

[0053] The flipping mechanism 5 is a servo motor 53 directly connected to the drive shaft 55 via a coupling. The flipping wheel 57 is installed on the drive shaft 55. The pusher unit 4 pushes the mold strip 7 onto the flipping wheel 57. The flipping wheel 57 drives the mold strip 7 to flip 90°. The mold strip 7 flipping guard 59 installed in the middle of the flipping mechanism 5 ensures that the mold strip 7 will not fly out due to centrifugal force when flipping.

[0054] Please see Figure 8The specific structure of the feeding mechanism 6 is exemplarily given, and it also includes a feeding mechanism 6. The feeding mechanism 6 includes a pusher 61 that reciprocates along the y-axis, corresponding to the position of the flipped die 7, and pushes the die 7 along the y-axis through the discharge port 561 to the next station. The reciprocating pusher 61 discharges the flipped die 7. The feeding mechanism 6 is a servo motor driven slide module 62. The module drives the pusher 61 connected to it to perform back-and-forth reciprocating motion, pushing the die 7 that has been flipped 90° in the flipping mechanism 5 to the next station.

[0055] Please continue reading Figure 8 The feeding mechanism 6 also includes a servo motor driven slide module 62, which includes a slide 621 that reciprocates along the y-axis. A pusher 61 is synchronously connected to the slide 621 via a connecting frame 63. After the die strip 7 is rotated 90 degrees to align with the discharge port 561, the slide 621 of the servo motor driven slide module 62 drives the pusher 61 to move the die strip 7 along the y-axis. The slide 621 of the servo motor driven slide module 62 drives the pusher 61 to move the die strip 7.

[0056] Please see Figure 9 To achieve automatic feeding, the feeding mechanism also includes a mold conveying unit 2. The mold conveying unit 2 includes two sets of synchronously moving modules 21 that move in opposite directions along the x-axis, driving the mold strip 7 to move towards the center of the frame 1. This enables the mold strip 7 to be fed from both sides of the frame 1 to the center of the frame 1.

[0057] Please see Figure 10 The mold conveying unit 2 mentioned above will be described in detail below. Each group of synchronous moving modules 21 includes two horizontally opposite conveying modules 211. Each conveying module 211 includes a first synchronous pulley 2111 and a second synchronous pulley 2112 located at the same horizontal height, as well as a drive pulley 2113 and a synchronous belt 2114. A first tension pulley 2115 and a second tension pulley 2116 are arranged on both sides of the drive pulley 2113. The synchronous belt 2114 is sequentially wound around the outer periphery of the drive pulley 2113, the second tension pulley 2116, the first synchronous pulley 2111, the second synchronous pulley 2112, and the first tension pulley 2115 in a counterclockwise direction. This causes the two synchronous belts 2114 to move synchronously and convey the mold strips 7. The mold conveying unit 2, as the conveying device for the mold strips 7, is driven by a servo motor to move the synchronous pulley and the synchronous belt mounted on the synchronous pulley, driving the 36 mold strips on the synchronous belt to move towards the center of the platform machine.

[0058] Please continue reading Figure 10A drive source 2117 with an output end is provided on the outer side of the drive pulley 2113 of one of the conveying modules 211. A synchronous shaft 2118 is provided between the first synchronous pulleys 2111 of the two conveying modules 211, so that the two first synchronous pulleys 2111 rotate synchronously. The output end of the drive source 2117 drives the drive pulley 2113 to rotate, and the drive pulley 2113 drives the first synchronous pulley 2111 and the second synchronous pulley 2112 to rotate through the synchronous belt 2114, conveying the module 7 to the center of the frame 1. A drive source 2117 is provided on one side to drive the synchronous belts 2114 on both sides to move synchronously.

[0059] Please continue reading Figure 10 The second synchronous pulleys 2112 of the two sets of synchronous moving modules 21 are coaxially arranged and rotate synchronously. This ensures the consistency of the actions of the two sets of synchronous moving modules 21.

[0060] Please see Figure 11 , Figure 12 and Figure 13 The slitting unit 3 includes a drive module 31 and a lifting module 32. The drive module 31 includes at least two rotating lifting gears 313. The lifting module 32 includes at least two lifting racks 325. A central box 326 is mounted on the top of each lifting rack 325. Positioning blocks 327 are mounted on both the left and right sides of the top of the central box 326. A pressure cover 328 is mounted on the top of each positioning block 327, forming a positioning groove between the pressure cover 328 and the positioning block 327. The lifting gears 313 mesh with the lifting racks 325. The lifting gears 313 rotate and drive the lifting racks 325 to rise or fall, thereby driving the central box 326 to rise or fall. This achieves the lifting and lowering of the central box 326 along the z-axis.

[0061] Please see Figure 12 Specifically, the structure of the drive module 31 is given by way of example. The drive module 31 also includes a drive motor 311. The output end of the drive motor 311 is provided with a rotating shaft 312. Two lifting gears 313 are provided on the outer wall of the rotating shaft 312. The output end of the drive motor 311 drives the lifting gears 313 to rotate through the rotating shaft 312.

[0062] Please see Figure 13 The structure of the lifting module 32 is specifically exemplarily given. The lifting module 32 also includes an intermediate connecting plate 321. An adjustment plate 322 is embedded in the center of the intermediate connecting plate 321. Hollow seats 323 are provided on both the left and right sides of the base of the adjustment plate 322, and an arc groove 324 is opened on the outer wall. The lifting rack 325 is inserted into the inner cavity of the hollow seat 323.

[0063] It should be noted that the slitting unit 3 is driven by a motor 311 connected to a rotating shaft 312 via a coupling. The rotating shaft 312 and two lifting gears 313 on the rotating shaft 312 reciprocate. The lifting gears 313 mesh with the lifting rack 325, which drives the center box 326 to complete the lifting action. The center box 326 is equipped with a positioning block 327, which is used to position the mold strips 7 on the synchronous belt in the mold conveying unit 2, so that only one mold strip 7 can stop on the positioning block 327 at a time. When the drive motor 311 drives the center box 326 to rise, it drives one mold strip 7 to rise, and the other mold strips 7 are blocked on the outside of the center box 326. When the center box 326 descends, there are no mold strips 7 on the positioning block 327. After descending to the bottom, the mold strips 7 on the outside of the center box 326 can stop on the positioning block 327 again. In this way, the 36 mold strips 7 are separated one by one and sent to the next station.

[0064] Please see Figure 14 The following is a specific example of the aforementioned lever unit 4. The lever unit 4 is located between two drive shafts 55. The lever unit 4 includes: a set of active modules and two sets of driven modules. The active module includes a lever motor 41 and an active gear 42 disposed at the output end of the lever motor 41. Each driven module includes a bearing seat 43 and a passive gear 44 rotatably connected to the bearing seat 43. The passive gear 44 meshes with the active gear 42. Each lever module includes a crank 46, bearings 48 rotatably connected to the left and right sides of the bottom end of the crank 46, and a lever shaft 45 disposed at the center of the crank 46. The lever shaft 45 is coaxial with and fixedly connected to the passive gear 44. The structure of the lever unit 4 is specifically exemplarily given.

[0065] Please see Figure 15 To ensure consistency during the operation of the lever, the lever unit 4 also includes a connecting rod module, which includes two parallel connecting rods 47, which are rotatably connected between the two ends of the two cranks 46 and form a parallelogram with the two cranks 46.

[0066] It should be noted that the slitting unit 4 is driven by the slitting motor 41, which drives the active gear 42 mounted on the slitting motor 41. The active gear 42 then drives the passive gears 44 on both sides to move. The slitting shaft 45 is mounted on the passive gear 44, and the crank 46 is mounted on the other end of the slitting shaft 45. The cranks 46 on the two slitting shafts 45 are connected by the connecting rod 47 to ensure the consistency of their movement when slitting. This ensures that after the center box 326 in the slitting unit 2 is raised to the position, the mold strip 7 on its positioning block 327 will not be inconsistent in its front and back positions when it is slitting away.

[0067] The slitting unit 3 is located where 36 die strips are slitted from the center and then transferred to the flipping mechanism 5. This reduces the space wastage caused by the slitting unit 3 being located on both sides of the equipment and the way the die strips are fed in, thus reducing the size of the equipment.

[0068] The mold strip flipping guard and mold strip positioning block in the flipping mechanism 5 restrict the degree of freedom of the mold strip when the flipping wheel is working, so that it moves on a fixed trajectory, ensuring safety and running speed.

[0069] Previously, when the platform machine reached a speed of 50 strips per minute, it would jump. After modification, experiments have shown that it can now reach 70 strips per minute.

[0070] The specific working process of the platform machine is as follows: When 36 die strips move towards the center of the platform machine via the synchronous belt 2114 in the die conveying unit 2, the 36 die strips are conveyed to the positioning block 327 of the center box 326 in the slitting unit 3. One die strip is stored on the positioning block 327 of the center box 326 in the slitting unit 3. Driven by the drive motor 311, the slitting unit 3 drives the rotating shaft 312 and the lifting gear 313 on the rotating shaft 312 to move. The lifting gear 313 meshes with the lifting rack 325, causing the center box 326 to rise, so that the center box 326... The die strip 7 on the die set enters the die set unit 4, while the other die strips 7 are still waiting on the die conveying unit 2. When the slitting unit 3 is in place, the die set motor 41 of the die set unit 4 starts. The die set motor 41 drives the drive gear 42 mounted on the die set motor 41, which in turn drives the driven gears 44 on both sides, the die set shaft 45 mounted on the driven gears 44, and the crank 46 mounted on the other end of the die set shaft 45 to rotate. The crank 46 moves the die strip 7 on the die set unit 4 onto the flipping wheel 57 of the flipping mechanism 5, and then the die set unit 4 stands upright. Returning to the origin, the center box 326 in the slitting unit 3 descends to receive the next die strip from the synchronous belt of the die conveying unit 2, waiting for the next upward movement; when the die strip enters the flipping wheel 57 in the flipping mechanism 5, the strip-shifting unit 4 returns to the origin, and at the same time, the pusher 61 of the strip feeding mechanism 6 returns to its original position, and the flipping mechanism 5 starts; the servo motor 53 of the flipping mechanism 5 is directly connected to the drive shaft 55 through a coupling, and the flipping wheel 57 is installed on the drive shaft 55. The strip-shifting unit 4 moves the die strip 7 onto the flipping wheel 57, and the flipping wheel 57 drives the die strip 7 to rotate 90°. The die strip 7 is prevented from flying out due to centrifugal force during flipping by the die strip flipping guard 59 installed in the middle of the flipping mechanism 5. When the die strip 7 reaches the position of the feeding mechanism 6, the servo motor of the feeding mechanism 6 drives the slide module 62, which drives the pusher 61 connected to it to perform back-and-forth reciprocating motion, pushing the die strip 7 that has been flipped 90° in the flipping mechanism 5 to the next single machine. At this time, the slitting unit 3 starts, and the center box 326 carries the die strip 7 up to enter the next cycle of motion. When the feeding mechanism 6 performs the feeding and return actions, the flipping mechanism 5 must not move.
