Description

Technical Field

[0001] The utility model relates to a capsule machine, and more particularly to a capsule pre-demoulding device. Background Art

[0002] A capsule machine is a special device for producing hollow hard capsules and includes a needle die for capsule forming. The process of dipping the needle die into a glue solution to pick up a layer of film, then drying, and finally removing the dried capsule from the die is called demoulding. In the existing demoulding process, a demoulding mechanism is used to achieve successful demoulding in one go. This process is stable and reliable when the operating speed of the capsule machine is 40 rods per minute. However, with the development and upgrade of capsule machine technology, the operating speed of the capsule machine is getting faster and faster. When the operating speed of the capsule machine exceeds 40 rods per minute, the demoulding time is very short, and the phenomenon of demoulding failure often occurs. Summary of the Utility Model

[0003] In order to solve the problems such as demoulding failure during the high-speed operation of the capsule machine in the above-mentioned prior art, the utility model provides a capsule pre-demoulding device.

[0004] According to the capsule pre-demoulding device of the utility model, it includes a driving plate, a clamping spring plate and an energy storage spring plate. Among them, the driving plate is movably installed on the energy storage spring plate and cooperates with the energy storage spring plate to compress the energy storage spring plate to store energy. The clamping spring plate is driven inside the driving plate and is movably installed on the energy storage spring plate and cooperates with the energy storage spring plate to make the energy storage spring plate clamp the capsule. The energy stored in the energy storage spring plate drives the clamped capsule to be pulled up from the die and become loose for pre-demoulding.

[0005] In a preferred embodiment, the clamping spring plate clamps the capsule after the energy storage spring plate is compressed, the clamping spring plate remains stationary when the energy storage spring plate is released, and the clamping spring plate releases the capsule after the energy storage spring plate is released.

[0006] In a preferred embodiment, the driving plate has a first main body, the first main body is U-shaped and includes a first top wall and first side walls vertically hanging downward from opposite sides of the first top wall.

[0007] In a preferred embodiment, the clamping spring plate has a second main body, the second main body is U-shaped and includes a second top wall and second side walls vertically hanging downward from opposite sides of the second top wall; the second main body is located inside the first main body; the second top wall is parallel to the first top wall; the second side walls are parallel to the first side walls.

[0008] In a preferred embodiment, the energy storage spring plate has at least two clamping seats, each clamping seat includes a third main body, the third main body is U-shaped and includes a bottom wall and third side walls vertically extending upward from opposite sides of the bottom wall; the bottom wall is parallel to the first top wall; the third side walls are perpendicular to the first side walls.

[0009] In a preferred embodiment, the bottom wall is a V-shaped plate. The V-shaped plate stores energy when flattened and deformed, and releases energy when it resumes its V shape.

[0010] In a preferred embodiment, the first side wall has a limiting groove, and the third side wall is inserted into the limiting groove for cooperation.

[0011] In a preferred embodiment, the clamping spring plate has an insertion portion that hangs down from the bottom edge of the second side wall. Each clamping seat includes a hoop portion.

The insertion portion is inserted into the bayonet of the adjacent clamping seat so that the two opposite hoop portions of each clamping seat clasp to clamp the capsule therein.

[0012] In a preferred embodiment, a plurality of insertion portions are arranged at intervals from each other.

[0013] In a preferred embodiment, the driving plate has a folding portion that is inclined and folded inward from the bottom edge of the first side wall. The folding portion acts on the insertion portion to disengage it from the bayonet of each clamping seat to release the capsule.

[0019] The following presents the preferred embodiments of the present invention in conjunction with the accompanying drawings and describes them in detail.

[0020] As Figure 1As shown, the capsule pre-demolding device A according to a preferred embodiment of the present utility model is placed above the mold and descends for pre-demolding, and then ascends after the pre-demolding is completed. In this embodiment, the mold is a thirty-six row needle mold, and each row of needle mold has thirty-six capsules B to be demolded. It should be understood that the number of rows and the number of the needle molds here are only examples rather than limitations.

[0021] As Figure 2 shown, the capsule pre-demolding device A includes a driving plate 1, a clamping spring plate 2, and an energy storage spring plate 3. Among them, the driving plate 1 is connected to an actuator (not shown) to be lifted and lowered under the action of the execution action. The driving plate 1 is movably installed on the energy storage spring plate 3 and cooperates with the energy storage spring plate 3 to compress the energy storage spring plate 3 to store energy. The clamping spring plate 2 is driven inside the driving plate 1 and is movably installed on the energy storage spring plate 3 and cooperates with the energy storage spring plate 3 to enable the energy storage spring plate 3 to clamp the capsule B. The energy stored in the energy storage spring plate 3 drives the clamped capsule B to be pulled out from the mold and loosened for pre-demolding. Due to the loosening of the capsule B, the formal demolding of the capsule B from the mold only requires a very small force to complete, ensuring the success of demolding, reducing the demolding power and demolding time, and improving the demolding efficiency and the finished product rate.

[0022] The driving plate 1 has a first main body 11 and a folding part 12. Among them, the first main body 11 is U-shaped and includes a first top wall 111 and first side walls 112 vertically hanging downward from opposite sides of the first top wall 111. The bottom of the first side wall 112 has a limiting groove 112a, and the folding part 12 is inclined and folded inward from the bottom edge of the first side wall 112 between the limiting grooves 112a. In this embodiment, the first top wall 111 has seven first openings 111a, and the first side wall 112 has seven pairs of limiting grooves 112a for pre-demolding seven capsules. It should be understood that the number of the openings and the limiting grooves here are only examples rather than limitations.

[0023] The clamping spring plate 2 has a second main body 21 and insertion parts 22. Among them, the second main body 21 is U-shaped and includes a second top wall 211 and second side walls 212 vertically hanging downward from opposite sides of the second top wall 211. A plurality of insertion parts 22 are vertically hanging downward from the bottom edge of the second side wall 212 at intervals. In this embodiment, the second top wall 211 has seven second openings 211a (six full openings and two half openings), and the clamping spring plate 2 has seven insertion parts 22 for pre-demolding seven capsules. It should be understood that the number of the openings and the insertion parts here are only examples rather than limitations.

[0024] The energy storage spring plate 3 has a plurality of clamping seats 3a. In the present embodiment, the energy storage spring plate 3 has seven clamping seats 3a for pre-demolding seven capsules. It should be understood that the number of clamping seats here is only for example and not for limitation. Each clamping seat 3a includes a third main body 31 and a hoop portion 32, wherein the third main body 31 is U-shaped and includes a bottom wall 311 and a third side wall 312 extending vertically upward from opposite sides of the bottom wall 311, the bottom wall 311 is a V-shaped plate and has a third opening 311a for capsule B to pass through, and two opposite hoop portions 32 are respectively fixedly connected to the top of the third side wall 312, and the end of each hoop portion 32 is bent to form a bayonet 32a that is open in opposite directions.

[0025] In a specific application process, the actuator first applies a downward force to the driving plate 1 to make it descend, and the third side wall 312 of the clamp seat 3a of the energy storage spring plate 3 is inserted into the limiting groove 112a of the driving plate 1 for matching. Figure 3 As shown, continuing to press the driving plate 1 downward will apply a force to the bottom wall 311 of the clamp seat 3a of the energy storage spring plate 3 so that the V-shaped plate is flattened (see Figure 4 ) is deformed to store energy, and at the same time, the clamping spring plate 2 is lowered, and the insertion portion 22 of the clamping spring plate 2 is gradually inserted into the bayonet 32a of the adjacent clamping seat 3a so that the clamping hoop portion 32 of each clamping seat 3a is closed to clamp the capsule B therein. Figure 4 As shown, after the actuator releases the driving plate 1, the V-shaped plate of the bottom wall 311 of the clamp seat 3a of the energy storage spring plate 3 returns to a V-shape to release energy, exerting an upward force on the driving plate 1 to make it rise. During the rising process, the folded portion 12 of the driving plate 1 (see Figure 3 ) acts on the insertion portion 22 of the clamping spring plate 2 to disengage it from the bayonet 32a of each clamping seat 3a to release the capsule B, completing the pre-demolding.

[0026] Obviously, the energy storage spring plate 3 of the capsule pre-demolding device A of the utility model is first compressed to store energy, and the clamping spring plate 2 clamps the capsule B after the energy storage spring plate 3 completes compression. When released, the energy storage spring plate 3 is released first, and the clamping spring plate 2 remains stationary. After the energy storage spring plate 3 is released, the clamping spring plate 2 releases the capsule B, thereby achieving the purpose of loosening the capsule B from the mold.

The above embodiments of the utility model can also be modified in various ways. That is, all simple, equivalent changes and modifications made according to the claims and the contents of the specification of the utility model application fall within the scope of protection of the claims of the utility model patent.
