Description

A capsule mold flipping structure with braking components Technical Field

[0001] This utility model relates to the field of capsule production equipment, and in particular to a capsule mold flipping structure with a braking component. Background Technology

[0002] During capsule production, the angles of operations such as oiling and gluing vary. Therefore, after the oiling operation is completed, the capsule mold needs to be flipped from a horizontal position to an upright position using a flipping structure to prepare for the subsequent gluing operation.

[0003] Existing capsule mold flipping structures, such as the utility model patent with publication number CN211485723U, include a mold strip flipping mechanism and a power device and synchronous transmission mechanism for driving the mold strip flipping mechanism to rotate. One side of the mold strip is limited in the mold strip groove on the mold strip flipping mechanism and flips downward by 90° with the mold strip flipping mechanism, thereby flipping downward to an upright state. However, in this technical solution, when the mold strip moves along the length of the mold strip groove after extending into the mold strip groove, it is only by the sequential pushing of subsequent mold strips that the mold strip moves relative to the mold strip groove to a preset position. This causes the final position of the mold strip to deviate from the initial preset position due to inertial force or rebound force, which is not conducive to the flipping structure driving the capsule mold to flip stably. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing a capsule mold flipping structure with a braking component. The braking component can prevent the capsule mold from moving along the length of the flipping groove, which helps to keep the capsule mold stably stationary in a preset position, thereby facilitating the orderly flipping operation of multiple capsule molds.

[0010] Preferably, the second lifting platform has an installation channel extending longitudinally, and a lifting seat is fixedly connected to the second lifting platform.

[0027] Capsules are common pharmaceutical packaging materials, and capsule molds 200 are essential production tools for capsule manufacturing. A capsule mold 200 includes a strip 201 and several capsule cores 202 arranged along the length of the strip 201. A flipping plate 2011 is formed on the side of the strip 201, positioned between the side of each capsule core 202 and the side of the strip 201. A limiting plate 2012 is formed at the front end of the strip 201, positioned between the front side of the capsule core 202 and the front face of the strip 201. Each capsule core 202 includes a glue-dipping rod 2021 at its free end and a connecting rod 2022 connecting the glue-dipping rod 2021 and the strip 201. The glue-dipping rod 2021 is used to dip the capsule core in glue to form a semi-capsule shell.

[0028] As shown in Figures 1-4, as an embodiment of this utility model, a capsule mold flipping structure with a braking component is provided, including a flipping shaft 1, a flipping component 2, a flipping drive mechanism 4, and a braking component 8. The flipping shaft 1 is arranged horizontally, and the flipping drive mechanism 4 drives the flipping shaft 1 to rotate around its axis. The flipping component 2 is coaxially arranged with and relatively fixed to the flipping shaft 1, and can rotate with the rotation of the flipping shaft 1. The flipping component 2 has a flipping groove 20 arranged parallel to the flipping shaft 1 for limiting the strip 201. When the flipping component 2 rotates with the flipping shaft 1 around its axis, it can drive the strip 201 and the entire capsule mold 200, which are limited in the flipping groove 20, to flip downwards. The flipping groove 20 passes through the inlet end 23 and the outlet end 24 of the flipping component 2, so that the capsule mold 200 can extend into the flipping groove 20 through the inlet end 23 of the flipping component 2 and extend out of the front end of the flipping groove 20 through the outlet end 24 of the flipping component 2. The braking component 8 includes brake elements 81 arranged at intervals relative to the side of the strip 201. In this embodiment, the flipping groove 20 has a groove bottom surface for supporting and limiting the bottom side of the strip plate 201. The brake component 8 is arranged above the flipping component 2 in a height-adjustable manner. When the capsule mold 200 moves forward along the length direction of the flipping groove 20 under the action of inertial force, or moves backward along the length direction of the flipping groove 201 under the action of rebound force, the brake component 81 can move downward with the brake component 8 towards the side of the strip plate 201 and press against the upper side of the strip plate 201, so that the strip plate 201 is firmly positioned between the brake component 81 and the groove bottom surface, so as to prevent the capsule mold 200 from moving along the length direction of the flipping groove 20, that is, to prevent the capsule mold 200 from moving forward or backward. This is conducive to driving the capsule mold 200 to stay stably in the preset position, thereby facilitating the orderly flipping operation of multiple capsule molds 200. In another embodiment of this utility model, the flipping groove 20 has a groove bottom surface for supporting and limiting the lower side of the strip 201, and a groove top surface for limiting the upper side of the strip 201. The brake component 8 is arranged vertically below the flipping component 2, so that when the capsule mold 200 moves forward along the length direction of the flipping groove 20 under the action of inertial force, or moves backward along the length direction of the flipping groove 20 under the action of rebound force, the brake component 81 can move upward with the brake component 8 towards the side of the strip 201 and press against the lower side of the strip 201, so that the strip 201 is firmly positioned between the brake component 81 and the groove top surface. This also prevents the capsule mold 200 from moving along the length direction of the flipping groove 20, that is, prevents the capsule mold 200 from moving forward or backward, which is conducive to driving the capsule mold 200 to stay stably in the preset position, thereby facilitating the stable flipping operation of the capsule mold 200.In other embodiments, the flipping member 2 may also be provided with an intermediate part (not shown in the figure) that can press against the side of the strip 201. The side of the strip 201 is indirectly pressed by the brake member 81 pressing against the intermediate part, which can also prevent the capsule mold 200 from moving forward or backward.

[0029] As shown in Figure 1, in some specific embodiments, a support base 73 for mounting on an external frame is also included. The brake component 8 also includes a lifting frame 82 that is vertically connected to the support base 73 and a lifting drive mechanism 9 for driving the lifting frame 82 to move up and down relative to the support base 73. The brake component 81 is connected to the lifting frame 82 and can move up and down with the lifting frame 82 under the drive of the lifting drive mechanism 9 between an open position that is spaced apart from the side of the strip 201 and a braking position that presses against the side of the strip 201 or presses against the side of the strip 201 through an intermediate member.

[0030] As shown in Figure 2, in some specific embodiments, a lifting channel 731 is provided through the support base 73. The lifting frame 82 includes a lifting shaft 821 sleeved in the lifting channel 731 and capable of moving up and down along the lifting channel 731, a first lifting platform 822 connected to the lower end of the lifting shaft 821 and arranged below the support base 73, and a second lifting platform 823 connected to the upper end of the lifting shaft 821 and arranged above the support base 73. The brake component 81 is connected to the first lifting platform 822 and can press against the upper side of the strip plate 201 as the lifting frame 82 descends, thereby firmly positioning the strip plate 201 between the brake component 81 and the bottom surface of the groove to prevent the capsule mold 200 from moving along the length direction of the flipping groove 20.

[0031] In some specific embodiments, the lifting drive mechanism 9 includes a lifting motor 91 mounted on a support base 73 and a lifting transmission component connected between the output shaft of the lifting motor 91 and the second lifting platform 823. The lifting transmission component includes a longitudinally arranged screw (not shown in the figure) and a screw bearing 92 rotatably connected to the screw. One of the screw and the screw bearing 92 is fixedly connected to the second lifting platform 823, and the other is fixedly connected to the output shaft of the lifting motor 91 and can rotate around the axis of the screw with the output shaft of the lifting motor 91, so as to drive the screw bearing 92 to move along the length direction of the screw, thereby driving the second lifting platform 823 to move up and down relative to the output shaft of the lifting motor 91.

[0032] In some specific embodiments, the lifting motor 91 is mounted and positioned above the second lifting platform 823 via a support frame 732. The output shaft of the lifting motor 91 is arranged on its lower side and coaxially with the screw component. The screw bearing 92 is coaxially arranged with and relatively fixed to the output shaft of the lifting motor 91. This structure is simple and has high transmission efficiency. The screw component is relatively fixed to the second lifting platform 823 and extends out of the upper side of the second lifting platform 823. The screw bearing 92 has an active channel extending upward from its lower side for rotatably connecting with the screw component and allowing the screw component to move along its axial direction. The lifting motor 91 and the second lifting platform 823 are arranged at intervals to form a lifting space for the lifting movement of the second lifting platform 823.

[0033] As shown in Figure 2, in some specific embodiments, a mounting channel 8231 is longitudinally provided on the second lifting platform 823. A lifting seat 8232 is fixedly connected to the second lifting platform 823. The lifting seat 8232 includes a lifting column passing through the mounting channel 8231 and a mounting platform extending outward from the outer periphery of the lifting column. The mounting platform is fixedly connected to the second lifting platform 823 by screws or other connecting parts. Optionally, the mounting platform is arranged on the upper side of the second lifting platform 823, which can limit it on the upper side of the second lifting platform 823 and prevent the lifting seat 8232 from falling off the second lifting platform 823. A connecting channel is provided through the lifting column along its axial direction. The lifting column extends downward to protrude below the second lifting platform 823, thereby increasing the connection area between the lifting column and the connecting channel and improving the stability of the connection. A channel 733 is longitudinally provided on the support base 73. A positioning seat 734 is fixedly connected to the support base 73 and arranged below the channel 733. A positioning channel 7341 is longitudinally provided on the positioning seat 734. The screw shaft passes through the connecting channel and is fixedly connected to the connecting channel. The upper and lower ends of the screw shaft extend out of the upper and lower sides of the lifting seat 8232, respectively. The upper end of the screw shaft is rotatably connected to the screw bearing 92, and the lower end of the screw shaft is sleeved in the positioning channel 7341 and is telescopically connected to the positioning channel 7341. While the lifting frame 82 is driven to move up and down by the screw shaft, the upper and lower ends of the screw shaft are positioned by the screw bearing 92 and the positioning channel 7341, respectively. This improves the stability of the lifting movement of the screw shaft and the lifting frame 82, thereby helping to stably prevent the capsule mold 200 from moving along the length direction of the flipping groove 20.

[0034] In some specific embodiments, a second channel 735 is longitudinally provided on the support base 73, and a guide seat 736 is fixedly connected to the support base 73. The guide seat 736 includes a guide post passing through the second channel 735 and a base platform extending outward from the outer periphery of the guide post. The base platform is fixedly connected to the support base 73 by screws or other connecting parts. Optionally, the base platform is arranged on the upper side of the support base 73, which can limit it on the upper side of the support base 73 and prevent the guide seat 736 from falling off the support base 73. A guide channel is provided through the guide post along its axial direction, forming the lifting channel 731. The guide post extends downward to protrude below the support base 73, thereby increasing the contact area between the guide channel and the lifting shaft 821 and improving the stability of the lifting shaft 821's lifting movement along the guide channel.

[0035] As shown in Figure 1, in some specific embodiments, two sets of flipping shafts 1, flipping components 2, and brake components 8 are arranged side by side, which can simultaneously prevent the capsule molds 200 in the flipping grooves 20 of the two sets of flipping components 2 from moving along the length direction of the flipping grooves 20. Two sets of lifting shafts 821 are also arranged at intervals along the direction perpendicular to the flipping shafts 1, which improves the balance of the lifting movement of the brake components 8 and the pressure on the sides of the strips 201 of the two capsule molds 200. The two brake components 81 are respectively connected to the lower side of the first lifting platform 822, and can move up and down simultaneously with the lifting frame 82 between an open position relatively spaced from the side of the corresponding strip 201, and a braking position that presses against the side of the corresponding strip 201 or presses against the side of the corresponding strip 201 through an intermediate component. The two brake components 81 are staggered between the two sets of lifting shafts 821. This staggered arrangement allows the brake components 81 and the lifting shafts 821 to be connected to different positions on the first lifting platform 822, facilitating the connection between the brake components 81 and the lifting shafts 821 and the first lifting platform 822.

[0036] As shown in Figure 3, in some specific embodiments, the brake component 81 and the lifting frame 82 are connected by an elastic buffer assembly 83. The elastic buffer assembly 83 includes a connecting shaft 831 and an elastic reset component 832 arranged longitudinally. The elastic reset component 832 is set as a compression spring, which is simple and practical. In other embodiments, it can also be set as a soft silicone, soft rubber or other structure with elastic reset force. A first telescopic channel 8221 is provided longitudinally through the first lifting platform 822. The lower end of the connecting shaft 831 is fixedly connected to the brake component 81, and the upper end is telescopically inserted into the first telescopic channel 8221 and limited by a limiting part 8311 protruding on the outer periphery of the connecting shaft 831 on the upper side of the first lifting platform 822, to prevent the brake component 81 and the connecting shaft 831 from falling off the first lifting platform 822, and to allow the brake component 81 to rise with the first lifting platform 822 of the lifting frame 82. An elastic reset member 832 is arranged between the brake member 81 and the first lifting platform 822. When the first lifting platform 822 moves closer to the brake member 81 along the first telescopic channel 8221, it presses the brake member 81 to move away from the first lifting platform 822. This elastic reset member 832 provides elastic force to the brake member 81, pressing against the side of the strip 201. Compared to directly using a rigid structure to apply force to the brake member 81 pressing against the side of the strip 201, the elastic reset member 832 provides a certain degree of buffering, thus preventing impact on the side of the strip 201 and avoiding damage to the capsule mold 200, thereby extending the service life of the capsule mold 200. In this embodiment, the connecting shaft 831 and the limiting part 8311 are integrally set as a bolt structure, which is simple and practical.

[0037] In some specific embodiments, the first lifting platform 822 has a first positioning groove 8223 recessed upward from its lower side, the brake component 81 has a second positioning groove 8111 recessed downward from its upper side, and the upper end of the elastic reset component 832 is positioned in the first positioning groove 8223 and the lower end is positioned in the second positioning groove 8111, which facilitates the installation and positioning of the elastic reset component 832.

[0038] As shown in Figure 3, in some specific embodiments, the elastic buffer assembly 83 further includes a telescopic shaft 833 arranged longitudinally. A second telescopic channel 8222 is provided through the first lifting platform 822 longitudinally. The lower end of the telescopic shaft 833 is fixedly connected to the brake component 81, and the upper end is telescopically inserted into the second telescopic channel 8222. This allows the first lifting platform 822 to move up and down relative to the brake component 81, guided by the movement of the connecting shaft 831 along the first telescopic channel 8221 and the telescopic shaft 833 along the second telescopic channel 8222, thereby improving the stability of the first lifting platform 822 moving up and down relative to the brake component 81. A channel 3 8224 is longitudinally provided on the first lifting platform 822. A telescopic seat 8225 is installed on the first lifting platform 822, passing through the channel 3 8224. The upper and lower ends of the telescopic seat 8225 protrude from the upper and lower sides of the first lifting platform 822, respectively, and are axially positioned relative to the first lifting platform 822 by snap rings (not shown in the figure) arranged on the upper and lower sides of the first lifting platform 822. The second telescopic channel 8222 is set on the telescopic seat 8225 and is axially provided along the telescopic seat 8225. Since the upper and lower ends of the telescopic seat 8225 protrude from the upper and lower sides of the first lifting platform 822, the length of the second telescopic channel 8222 and the contact area with the telescopic shaft 833 are increased compared to setting the second telescopic channel 8222 directly on the first lifting platform 822, thereby improving the stability of the telescopic shaft 833 in the lifting and lowering movement along the second telescopic channel 8222.

[0039] As shown in Figure 4, in some specific embodiments, the brake component 81 includes a brake base 811 and a brake block 812 detachably connected to the brake base 811. The brake block 812 protrudes from the bottom surface of the brake base 811 for contacting the side of the strip 201. The brake block 812 can be detached from the brake base 811 for easy replacement and subsequent maintenance. The brake block 812 can be made of non-metallic materials such as plastic or rubber to avoid rigid collision between the brake block 812 and the strip 201, thus extending the service life of the capsule mold 200. The lower ends of the connecting shaft 831 and the telescopic shaft 833 are fixedly connected to the brake base 811, and the second positioning groove 8111 is recessed downward from the top surface of the brake base 811. The first push-down part 22 has a notch arranged corresponding to the brake component 81. When the flipping component 2 drives the capsule mold 200 to flip downward, the brake component 81 can pass through the notch without interfering with the rotation of the flipping component 2. This allows the flipping operation of the flipping component 2 and the upward movement of the brake component 81 to be carried out simultaneously, improving work efficiency.

[0040] In some specific embodiments, at least two telescopic shafts 833 and at least two connecting shafts 831 are symmetrically arranged, resulting in better balance in the connection between the brake component 81 and the first lifting platform 822. The connecting shafts 831 and telescopic shafts 833, corresponding to each set of brake components 81, are arranged on the same straight line, parallel to the top of the tilting groove 20. The two connecting shafts 831 are arranged outside the two telescopic shafts 833, resulting in a compact overall structure. An elastic reset component 832 is arranged between the two telescopic shafts 833, with the two telescopic shafts 833 symmetrically arranged on both sides of the elastic reset component 832. The two connecting shafts 831 are symmetrically arranged on both sides of the elastic reset component 832, ensuring the balance of the buffering effect of the elastic reset component 832. In other embodiments, the elastic reset component 832 can also be sleeved on the telescopic shaft 833 or on the connecting shaft 831, also achieving a certain degree of buffering effect.

[0041] As shown in Figure 2, in some specific embodiments, the flipping member 2 is coaxially arranged with the flipping shaft 1 and can rotate synchronously with the flipping shaft 1. Four flipping slots 20 are evenly arranged along the circumference of the flipping shaft 1. The flipping member 2 also has a first open portion 21 arranged on one side of each flipping slot 20 for arranging the capsule core rod 202, and a first pushing portion 22 arranged on the other side of each flipping slot 20 for abutting the side of the strip 201 away from the capsule core rod 202. The first pushing portion 22 is used to push the strip 201 downwards with the flipping member 2. The flipping member 2 can rotate continuously in the same direction, and each capsule mold 200 can sequentially extend into each flipping slot 20 from the inlet end 23 of the flipping member 2, and continuously drive each capsule mold 200 downwards through each flipping slot 20, improving the flipping efficiency of the capsule mold 200. Four flipping grooves 20 are evenly arranged along the circumference of the flipping shaft 1, so that each flipping groove 20 continuously and sequentially drives each capsule mold 200 to flip downwards by 90°. The operation of the lower capsule mold 200 moving out of the flipping groove 20 and the operation of the upper capsule mold 200 extending into the flipping groove 20 can be performed simultaneously, further improving the flipping efficiency of the capsule mold 200. In other embodiments, eight or other numbers of flipping grooves 20 are evenly arranged along the circumference of the flipping shaft 1 on the flipping member 2, which can also drive the capsule mold 200 to flip continuously. As another embodiment of this utility model, only one flipping groove 20 can be provided, and the flipping shaft 1 can be set to reciprocate at 90°. That is, after the flipping member 2 rotates forward, driving one capsule mold 200 to flip downwards by 90°, it rotates in the opposite direction by 90° so that the next capsule mold 200 can extend into the flipping groove 20 for the next round of flipping operation.

[0042] As shown in Figure 4, in some specific embodiments, a positioning component 3 is also included, which is coaxially arranged and relatively fixed with the flipping shaft 1. The positioning component 3 is arranged on one side of the outlet end 24 of the flipping component 2. The positioning component 3 has four limiting grooves 30 evenly arranged along the circumference of the flipping shaft 1 for limiting the limiting plate 2012. The limiting grooves 30 are arranged correspondingly to the flipping groove 20. This allows the capsule mold 200 to be limited in the flipping groove 20 of the flipping component 2 by the flipping plate 2011 on the side of the strip 201, and at the same time limited in the limiting groove 30 of the positioning component 3 by the limiting plate 2012 at the front end of the strip 201. The depth of the limiting groove 30 is greater than the depth of the flipping groove 20, which makes the center of gravity of the capsule mold 200 more stable during the downward flipping process with the capsule mold flipping structure 100. Therefore, the stability of the capsule mold 200 and the capsule mold flipping structure 100 is greatly improved, which is conducive to the stable and smooth flipping operation of the capsule mold 200 and facilitates the stable conveying to the glue dipping process in the subsequent process.

[0043] In some specific embodiments, the depth of the limiting groove 30 is greater than the width of the strip 201, so that the strip 201 can be completely limited within the limiting groove 30, which can better maintain the stability of the center of gravity of the capsule mold 200 during downward flipping. In other embodiments, the depth of the limiting groove 20 can also be set to be greater than the width of the flipping plate 2011, or greater than the distance between the central axis of the capsule core 202 and the outer side of the flipping plate 2011. Compared with the existing technology, which only uses the partial structure arranged on one side of the strip on the capsule core to interlock with the limiting groove, these embodiments can also improve the stability of the center of gravity of the capsule mold 200 during downward flipping to a certain extent.

[0044] In some specific embodiments, the width of the strip 201 is 9mm-14mm, especially 13mm-14mm. Compared with the conventional capsule mold strips in the prior art, which are set to be greater than 16mm, the strip 201 in this embodiment is narrower, making the structure more compact when multiple capsule molds are arranged together. This is beneficial for subsequent batch glue application operations, which not only reduces the cost of capsule molds but also improves production efficiency. In addition, since the front end of the strip 201 can be limited within the limiting groove 30 of the positioning member 3 by the limiting plate 2012, it can maintain the stability of the center of gravity and prevent it from falling during the downward flipping of the capsule mold 200.

[0045] As shown in Figure 4, in some specific embodiments, the flipping drive mechanism 4 includes two flipping drive motors 41 respectively arranged in front of the two positioning members 3, and two flipping transmission members (not shown in the figure) connected between the output shafts of the two flipping drive motors 41 and the correspondingly arranged flipping shafts 1. It can independently drive the two flipping shafts 1 to rotate through the two flipping drive motors 41 and the two flipping transmission members, which is convenient for installation, debugging and subsequent maintenance. Of course, in other embodiments, the two flipping shafts 1 can also be driven to rotate simultaneously by the same flipping drive motor 41 and flipping transmission member.

[0046] As shown in Figure 4, in some specific embodiments, a first auxiliary flipping component 5 and a second auxiliary flipping component 6 are also included, which are coaxially arranged and relatively fixed with the flipping shaft 1. The first auxiliary flipping component 5 is arranged between the flipping component 2 and the positioning component 3. The first auxiliary flipping component 5 has a second open portion 51 arranged corresponding to the first open portion 21 for arranging the capsule core 202, and a second pushing portion 52 arranged corresponding to the first pushing portion 22 for abutting the side of the strip 201 away from the capsule core 202. The second auxiliary flipping component 6 is arranged on the side of the flipping component 2 away from the positioning component 3. The second auxiliary flipping component 6 has a third open portion 61 arranged corresponding to the first open portion 21 for arranging the capsule core 202, and a third pushing portion 62 arranged corresponding to the first pushing portion 22 for abutting the side of the strip 201 away from the capsule core 202. The first auxiliary flipping component 5 and the second auxiliary flipping component 6 are used to assist the flipping component 2 in driving the capsule mold 200 to flip downward, thereby improving the stability of the flipping of the capsule mold 200. The first auxiliary flipping component 5 also has a first auxiliary plane 53 that is flush or substantially flush with the bottom surface of the flipping groove 20 and the bottom surface of the limiting groove 30. The second auxiliary flipping component 6 also has a second auxiliary plane 63 that is flush or substantially flush with the bottom surface of the flipping groove 20 and the bottom surface of the feeding area 720. The first auxiliary plane 53 and the second auxiliary plane 63 are used to support the strip 201, improve the stability of the capsule mold flipping structure 100 in supporting the capsule mold 200, and the first auxiliary plane 53 facilitates the smooth extension of the strip 201 into the limiting groove 30 along the first auxiliary plane 53, and the second auxiliary plane 63 facilitates the smooth extension of the strip 201 into the flipping groove 20 along the bottom surface of the feeding area 720.

[0047] In some specific embodiments, a first mounting base 71 and a second mounting base 72 for mounting on an external frame are also included. The first mounting base 71 includes a first mounting plate 711 and a second mounting plate 712 arranged opposite to each other, and a connecting plate 713 connecting the first mounting plate 711 and the second mounting plate 712. The second mounting plate 712 is arranged at intervals on the front side of the first mounting plate 711 and surrounds the first mounting plate 711 and the second mounting plate 712 to form a mounting area for arranging the flip transmission component. One end of the flip shaft 1 extends out of the positioning member 3 and is rotatably connected to the first mounting plate 711. The flip drive motor 41 is mounted on the outside of the second mounting plate 712. The flip drive motor 41 is coaxially arranged with the correspondingly arranged flip shaft 1. The flip transmission component is set as a coaxial transmission structure, which is simple in structure and has high transmission efficiency. The other end of the flipping shaft 1 extends out of the flipping member 2 and is rotatably connected to the second mounting base 72, thereby supporting and positioning both ends of the flipping shaft 1 through the first mounting base 71 and the second mounting base 72. Both ends of the flipping shaft 1 can rotate relative to the first mounting base 71 and the second mounting base 72 respectively. Rotary bearings for connecting with the flipping shaft 1 are respectively installed on the first mounting base 71 and the second mounting base 72, which facilitates the rotational movement of the flipping shaft 1 relative to the first mounting base 71 and the second mounting base 72.

[0048] In some specific embodiments, the upper part of the second mounting base 72 is formed with a feeding area 720 for the capsule mold 200 to extend horizontally into the flipping groove 20. The height of the bottom surface of the feeding area 720 is flush with or substantially flush with the height of the bottom surface of the flipping groove 20 above the flipping member 2, so that the strip 201 of the capsule mold 200 can move horizontally along the bottom surface of the feeding area 720 and the bottom surface of the flipping groove 20 above the flipping member 2 and enter the flipping groove 20, thereby improving the stability of the capsule mold 200 entering the flipping groove 20 and the positioning groove 30. A baffle plate 7111 is formed on the upper part of the first mounting base 71, which is arranged between the side of the flipping shaft 1 and the upper end face of the first mounting base 71 and can abut against the front end face of the strip 201. In this embodiment, the baffle plate 7111 is disposed on the first mounting plate 711 and arranged between the side of the first flipping shaft 1 and the upper end face of the first mounting plate 711. It can limit the strip 201 of the capsule mold 200 when it moves into the flipping groove 20 and the limiting groove 30, preventing the capsule mold 200 from moving excessively, thereby ensuring that the capsule mold 200 is limited within the flipping groove 20 and the limiting groove 30. In this embodiment, when the capsule mold 200 moves forward along the length of the flipping groove 20 and the limiting groove 30 via the strip plate 201 and bounces off the blocking plate 7111, and then moves backward along the length of the flipping groove 20 and the limiting groove 30, the brake member 81 moves downward toward the side of the strip plate 201 along with the brake component 8 and presses against the upper side of the strip plate 201, so that the strip plate 201 is firmly positioned between the brake member 81 and the bottom surface of the groove, thereby preventing the capsule mold 200 from moving along the length of the flipping groove 20, that is, preventing the capsule mold 200 from moving backward. This helps to keep the capsule mold 200 stably in the preset position, thereby preventing the capsule mold 200 from bouncing off the blocking plate 7111 and avoiding the capsule mold 200 from providing a reverse motion interference force to the forward movement of the subsequent capsule molds 200. This ensures the stability of the continuous conveying of each capsule mold 200 toward the capsule mold flipping structure, and at the same time facilitates the flipping component 2 to drive multiple capsule molds 200 to rotate in an orderly and continuous manner through multiple flipping grooves 20 under the drive of the flipping drive mechanism 4.
