Description

Technical Field

[0001] This invention relates to the field of pharmaceutical loading technology, and more specifically, to a loading template material gate closing device. Background Technology

[0002] During the process of loading the drug mold into the drug template, the drug mold shell needs to be placed into the hole of the drug template in a closed environment. Since the most precise control cannot be achieved when the drug mold is poured from the hopper into the drug template, a small amount of drug mold is often left after being loaded into the hole of the drug template, so the utilization rate of the drug template is low.

[0003] In conclusion, how to solve the problem of low utilization rate of drug templates is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a material gate closing device for a drug loading template, which can improve the efficiency of the drug mold falling into the drug mold hole.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A charging template material gate closing device includes:

[0007] A medicine mold mounting plate is used to hold medicine molds. The upper end face of the medicine mold mounting plate is fixedly provided with an annular structure. The cavity formed by the annular structure is connected to the discharge channel for discharging material. The medicine mold mounting plate is provided with medicine mold holes inside the annular structure.

[0008] A closed loop is rotatably fitted inside the annular structure. The closed loop has a window. When the window (2-3) is in the first position, the cavity is connected to the discharge channel (1-4); when the window (2-3) is in the second position, the cavity is disconnected from the discharge channel (1-4).

[0009] An inner substrate plate is movably disposed at the bottom of the drug molding plate, and the inner substrate plate is connected to the closed ring to drive the closed ring to rotate;

[0010] A power unit, connected to the inner substrate plate, drives the inner substrate plate to move relative to the drug mold plate.

[0011] Preferably, the inner substrate plate has holes corresponding to the drug mold holes.

[0012] Preferably, the outer side of the closed loop is provided with a meshing toothed ring, the meshing toothed ring is located on the outer side of the annular structure, the side of the inner substrate plate is provided with a rack, and the upper end face of the drug mold plate is rotatably provided with a closed gear, the closed gear meshing with the meshing toothed ring and the rack respectively.

[0013] Preferably, the inner substrate plate is provided with the rack on both sides, and the upper end face of the drug mold plate is provided with the closed gear on both sides. The closed gear on both sides meshes with the rack on both sides, and the closed gear meshes with the meshing tooth ring.

[0014] Preferably, the bottom of the pharmaceutical mold plate is provided with an inner liner groove, and the inner liner plate is provided with a sliding wing, which is installed in the inner liner groove.

[0015] Preferably, the bottom sidewall of the pharmaceutical mold plate is provided with an inner liner plate support pin for mounting the inner liner plate, the side of the inner liner plate is provided with a pin hole, the inner liner plate support pin is inserted into the pin hole, and the inner liner plate support pin is equipped with a spring.

[0016] Preferably, the bottom sidewall of the drug mold plate is provided with at least two inner liner plate support pins, each inner liner plate support pin is equipped with a spring, and the side of the inner liner plate is provided with at least two pin holes, with at least two inner liner plate support pins and at least two pin holes corresponding to each other.

[0017] Preferably, the power unit is a drive cylinder.

[0018] Preferably, the width of the window is greater than or equal to the width of the opening of the discharge channel near the end of the annular structure.

[0019] The drug loading template material gate closing device provided by the present invention includes a drug loading plate, a closing ring, an inner liner plate and a power device. The drug loading plate has an annular structure and a drug loading hole is provided inside the annular structure. The annular structure is connected to the discharge channel. The closing ring is rotatably fitted inside the annular structure and has an opening. The bottom of the drug loading plate has an inner liner plate and is connected to the power device to drive the inner liner plate to move.

[0020] In use, the power unit is started, which drives the inner substrate plate to move. At the same time, the inner substrate plate drives the closed ring to rotate so that the opening is misaligned with the outlet of the discharge channel, allowing the medicine mold to fall from the hopper onto the surface of the medicine mold hole inside the annular structure.

At the same time, the opening is aligned with the discharge channel, and the internal cavity of the annular structure is connected to the discharge channel.

[0021] Since the number of molds falling from the hopper into the annular structure may be greater than the number of mold holes, after the molds in the mold holes fall into the next process, the mold plate can be flipped so that the excess molds can enter the discharge channel through the opening and be poured out.

[0022] The closing device provided in this application can provide a closed space for the drug mold, thereby enabling mechanical movement of the drug mold loading plate. While allowing the drug mold to fall into the drug mold hole, it can prevent the drug mold from being poured out from the discharge channel, thereby improving the utilization rate of the drug mold hole of the drug mold loading plate and increasing the efficiency of the drug mold falling into the drug mold hole.

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

[0036] The core of this invention is to provide a material gate closing device for a drug loading template, which can improve the efficiency of the drug mold falling into the drug mold hole.

[0037] Please refer to Figures 1-6 , Figure 1 This is a schematic diagram of the structure of the charging template material gate closing device; Figure 2 This is a bottom schematic diagram of the charging template material gate closing device; Figure 3 This is a schematic diagram of the structure of the pharmaceutical mold assembly plate; Figure 4 This is a schematic diagram of the bottom of the pharmaceutical mold loading plate; Figure 5 This is a schematic diagram of a closed loop; Figure 6 This is a schematic diagram of the inner substrate.

[0038] This application provides a drug loading template material gate closing device, including a drug loading plate 1, a closing ring 2, an inner lining plate 6, and a power device 4. The drug loading plate 1 is used to load the drug mold. An annular structure 1-2 is fixedly provided on the upper end surface of the drug loading plate 1. The cavity formed by the annular structure 1-2 is connected to the discharge channel 1-4 for discharging. The drug loading plate 1 is provided with a drug mold hole 1-3 inside the annular structure 1-2. The closing ring 2 is rotatably sleeved on the inner side of the annular structure 1-2. The closing ring 2 is provided with an opening 2-3. When the opening 2-3 is in the first position, the cavity is connected to the discharge channel 1-4. When the opening 2-3 is in the second position, the cavity is disconnected from the discharge channel 1-4. The inner lining plate 6 is movably provided at the bottom of the drug loading plate 1. The inner lining plate 6 is connected to the closing ring 2 to drive the closing ring 2 to rotate. The power device 4 is connected to the inner lining plate 6 to drive the inner lining plate 6 to move relative to the drug loading plate 1.

[0039] Specifically, the medicine mold plate 1 is a rectangular plate with an annular structure 1-2 forming a circle in the middle of its upper end face. The medicine mold plate 1 inside the annular structure 1-2 is covered with medicine mold holes 1-3. The inner side of the annular structure 1-2 is rotatably provided with a closed ring 2 also forming a circle. The discharge channel 1-4 is located on one side of the annular structure 1-2 and communicates with the interior of the annular structure 1-2. The closed ring 2 has a rectangular window 2-3. The inner substrate plate 6 is located at the bottom of the medicine mold plate 1 and is connected to the power device 4.

[0040] In use, the power unit 4 is started, which drives the inner substrate plate to move. At the same time, the inner substrate plate 6 drives the closed ring 2 to rotate so that the window 2-3 is misaligned with the outlet of the discharge channel 1-4, and the medicine mold falls from the hopper into the surface of the medicine mold hole 1-3 inside the annular structure 1-2. Since the closed ring 2 is located inside the annular structure 1-2, the medicine mold is located inside the closed ring 2 and within the closed space of the closed ring 2. The medicine mold is screened into the medicine mold hole 1-3 by mechanical movement. At this time, the medicine mold is supported on the inner substrate plate 6. The power unit 4 is started, which moves the inner substrate plate 6 so that the medicine mold can no longer be supported on the inner substrate plate 6 and falls to the next process. At the same time, the window 2-3 is aligned with the discharge channel 1-4, and the internal cavity of the annular structure 1-2 is connected to the discharge channel 1-4.

[0041] Since the number of molds falling from the hopper into the annular structure 1-2 may be greater than the number of mold holes 1-3, after the molds in the mold holes 1-3 fall into the next process, the mold loading plate 1 can be flipped so that the excess molds can enter the discharge channel 1-4 through the opening 2-3 and be poured out.

[0042] The closing device provided in this application can provide a closed space for the drug mold, thereby enabling mechanical movement of the drug mold mounting plate 1. While allowing the drug mold to fall into the drug mold hole 1-3, it can prevent the drug mold from being poured out from the discharge channel 1-4, thereby improving the utilization rate of the drug mold hole 1-3 of the drug mold mounting plate 1 and improving the efficiency of the drug mold falling into the drug mold hole 1-3.

[0043] Optionally, the drug mold plate 1 can also be circular or other shapes.

[0044] Optionally, the ring structure 1-2 and the closed loop 2 can also be arranged into a rectangle or other shapes.

[0045] Optionally, windows 2-3 can also be in other shapes.

[0046] Optionally, the number of other mold holes 1-3 can also be set according to requirements.

[0047] Based on the above embodiments, the inner substrate 6 is provided with holes 6-3 corresponding to the drug mold holes 1-3.

[0048] Specifically, the inner substrate plate 6 is provided with holes 6-3 that correspond perfectly to the mold holes 1-3. When the mold falls from the hopper into the annular structure 1-2, the power device 4 drives the inner substrate plate 6 to move so that the holes 6-3 on the inner substrate plate 6 are misaligned with the mold holes 1-3 on the mold mounting plate 1. Since the size of the mold is similar to the size of the mold holes 1-3, the mold falls into the mold holes 1-3 and is supported on the inner substrate plate 6. After the mold is sieved into the mold holes 1-3 by mechanical movement, the power device 4 drives the inner substrate plate 6 to move so that the holes 6-3 correspond perfectly to the mold holes 1-3. At this time, the mold located in the mold holes 1-3 falls into the next process through the holes 6-3.

[0049] Holes 6-3 are provided in the inner substrate plate 6. By offsetting the holes 6-3 from the drug mold holes 1-3, the drug mold can be supported, which greatly reduces the movement time of the inner substrate plate 6 and thus improves the efficiency of the drug mold mounting.

[0050] Optionally, the shape of the eyelet 6-3 may not be the same as the shape of the mold hole 1-3.

[0051] Based on the above embodiment, a meshing toothed ring 2-1 is provided on the outer side of the closed ring 2. The meshing toothed ring 2-1 is located on the outer side of the annular structure 1-2. A rack 6-2 is provided on the side of the inner substrate plate 6. A closed gear 3 is rotatably provided on the upper end face of the drug mold plate 1. The closed gear 3 meshes with the meshing toothed ring 2-1 and the rack 6-2 respectively.

[0052] Specifically, the upper outer end of the closed ring 2 is connected to a meshing toothed ring 2-1, and the meshing toothed ring 2-1 is located on the outside of the annular structure 1-2, that is, the annular structure 1-2 is located between the closed ring 2 and the meshing toothed ring 2-1. The side of the inner substrate plate 6 is provided with a rack 6-2, and the upper end face of the drug mold plate 1 is provided with a closed gear 3, and the closed gear 3 is located on the side of the annular structure 1-2. The closed gear 3 meshes with the meshing toothed ring 2-1 and the rack 6-2 respectively.

[0053] When the molded medicine falls from the hopper into the annular structure 1-2, the power device 4 drives the inner substrate plate 6 to move. When the inner substrate plate 6 moves, it drives the side rack 6-2 to move. The rack 6-2 drives the closed gear 3 to rotate. Finally, the closed gear 3 drives the meshing gear ring 2-1 to rotate, that is, drives the closed ring 2 to rotate, so that the opening 2-3 of the closed ring 2 is misaligned with the discharge channel 1-4. At this time, the molded medicine is in the closed space inside the closed ring 2. When the molded medicine is screened into the molded medicine hole 1-3 by mechanical movement, the power device 4 drives the inner substrate plate 6 to move, which in turn drives the closed ring 2 to rotate, so that the opening 2-3 is aligned and connected with the discharge channel 1-4.

[0054] By setting up rack 6-2, closed gear 3 and meshing gear ring 2-1, the closing or opening of closed ring 2 can be controlled while adjusting the position of inner substrate plate 6, and the rotation of closed ring 2 can be automatically controlled, thereby improving work efficiency.

[0055] The meshing toothed ring 2-1 is positioned at the upper outer end of the closed ring 2, that is, the meshing toothed ring 2-1 is located at the upper end of the annular structure 1-2, so as to ensure that the meshing toothed ring 2-1 can pass smoothly through the discharge channel 1-4 when the closed ring 2 rotates. Optionally, the position of the meshing toothed ring 2-1 can also be set according to the height of the discharge channel 1-4.

[0056] Based on the above embodiments, racks 6-2 are provided on both sides of the inner substrate plate 6, and closed gears 3 are provided on both sides of the upper end face of the drug mold plate 1. The closed gears 3 on both sides mesh with the racks 6-2 on both sides, and the closed gears 3 mesh with the meshing gear rings 2-1.

[0057] Specifically, racks 6-2 are provided on both sides of the inner substrate 6, and closed gears 3 are provided on both sides of the annular structure 1-2. Therefore, when the meshing toothed ring 2-1 is driven to rotate by the racks 6-2 and the closed gears 3, the meshing toothed ring 2-1 can be subjected to relatively balanced forces, thereby avoiding jamming when the meshing toothed ring 2-1 rotates and ensuring the stability of the rotation of the meshing toothed ring 2-1 and the closed ring 2.

[0058] Optionally, other numbers of closed gears 3 can also be set.

[0059] Based on the above embodiments, the bottom of the drug mold loading plate 1 is provided with an inner liner plate groove 1-6, and the inner liner plate 6 is provided with a sliding wing, which is installed in the inner liner plate groove 1-6.

[0060] Specifically, the bottom sides of the drug mold loading plate 1 are provided with inner liner plate grooves 1-6, and the sides of the inner liner plate 6 are provided with sliding wings. The inner liner plate 6 is installed in the inner liner plate grooves 1-6 of the drug mold loading plate 1 through the sliding wings. The inner liner plate grooves 1-6 can ensure the movement direction of the inner liner plate 6 and at the same time provide support force to the inner liner plate 6 so that the inner liner plate 6 can be installed at the bottom of the drug mold loading plate 1.

[0061] Optionally, pulleys can be provided on both sides of the inner substrate 6.

[0062] Based on any of the above schemes, the bottom side wall of the drug mold plate 1 is provided with an inner liner plate support pin 1-5 for installing the inner liner plate 6. The side of the inner liner plate 6 is provided with a pin hole, the inner liner plate support pin 1-5 is inserted into the pin hole, and the inner liner plate support pin 1-5 is equipped with a spring 5.

[0063] Specifically, the bottom inner wall of the drug mold plate 1 is provided with inner lining plate support pins 1-5 along the direction of movement of the inner lining plate 6, one end of the inner lining plate 6 is provided with a pin hole, and a spring 5 is sleeved on the outside of the inner lining plate support pins 1-5.

[0064] When the power unit 4 drives the inner liner plate 6 to move outward along the inner liner plate slide groove 1-6, the spring 5 is in the reset state, and the hole 6-3 and the drug mold hole 1-3 are misaligned; when the power unit 4 drives the inner liner plate 6 to move inward along the inner liner plate slide groove 1-6, the spring 5 is compressed, and the hole 6-3 is aligned with the drug mold hole 1-3.

[0065] By setting the spring 5, a buffer force can be given to the inner substrate plate 6 to avoid excessive movement of the inner substrate plate 6 when it moves inward, which would cause the inner substrate plate 6 to collide with the bottom inner wall of the drug mold plate 1. At the same time, the excessive movement of the inner substrate plate 6 is limited to ensure that the hole 6-3 is aligned with the drug mold hole 1-3.

[0066] Based on the above embodiments, the bottom side wall of the drug mold plate 1 is provided with at least two inner lining plate support pins 1-5, each inner lining plate support pin 1-5 is equipped with a spring 5, and the side of the inner lining plate 6 is provided with at least two pin holes, and the at least two inner lining plate support pins 1-5 are inserted into the at least two pin holes one by one.

[0067] Specifically, the bottom side wall of the drug mold plate 1 is provided with two inner lining plate support pins 1-5, and the side of the inner lining plate 6 is provided with two pin holes. The two inner lining plate support pins 1-5 are symmetrically arranged, the two pin holes are symmetrically arranged, and both inner lining plate support pins 1-5 are provided with springs 5. This can ensure the buffering force of the springs 5 ​​while ensuring the stability of the inner lining plate 6 during movement and preventing the inner lining plate 6 from tilting.

[0068] Optionally, the inner lining plate support pins 1-5 and pin holes can also be set asymmetrically.

[0069] Based on any of the above schemes, the power unit 4 is a drive cylinder.

[0070] Specifically, the power unit 4 is a drive cylinder that can make the inner substrate plate 6 reciprocate, and it has a simple structure and low cost.

[0071] Optionally, the inner substrate 6 can also be moved by a lead screw nut or other means.

[0072] Based on any of the above schemes, the width of the window 2-3 is greater than or equal to the width of the opening of the discharge channel 1-4 near the end of the annular structure 1-2.

[0073] Specifically, the openings of window 2-3 and discharge channel 1-4 in the annular structure 1-2 are both rectangular and have the same height. The width of window 2-3 is greater than or equal to the width of the opening of discharge channel 1-4 in the annular structure 1-2. This ensures efficiency when pouring out excess medicine mold and avoids the time to pour out excess medicine mold due to window 2-3 being too small.

[0074] Optionally, the openings of the window 2-3 and the discharge channel 1-4 located in the annular structure 1-2 can also be of different shapes.

[0075] Optionally, the heights of the two can be different.

[0076] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0077] The foregoing has provided a detailed description of the charging template material gate closing device provided by the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
