This jamming during tableting not only affects the tableting efficiency but may also damage the product. Furthermore, the processing mold needs to be replaced according to processing requirements during tableting operations, which traditional equipment cannot meet. Summary of the Invention

The lower tablet pressing mechanism includes an external hydraulic module and an internal hydraulic module, which are slidably connected. The internal hydraulic module has a transmission telescopic plate installed inside, and the internal hydraulic module can drive the external hydraulic module to move upward through the transmission telescopic plate. When the rotating beam rotates around the rotating adjusting column, it can move the upper pressing mechanism above the lower pressing mechanism. When the lower pressing mechanism drives the internal hydraulic module to move upward, the internal hydraulic module contacts the interior of the upper pressing mechanism, which can drive the transmission telescopic plate to extend. When the transmission telescopic plate extends, the internal hydraulic module moves upward, which can drive the external hydraulic module to move synchronously. When the external hydraulic module and the internal hydraulic module extend into the interior of the upper pressing mechanism and continue to move upward, they can perform pressing operations. When the internal hydraulic module moves upward alone, it can drive the molded product to be demolded.

[0007] Preferably, a fixed limiting post is installed on the top of the processing table, and a limiting slot is opened inside the rotating beam. When the rotating beam rotates around the rotating adjusting post, it can be engaged with the outside of the fixed limiting post through the limiting slot.

An upper hydraulic chamber is connected to the bottom of the upper adjusting screw. A limit baffle is fixedly installed inside the upper hydraulic chamber. A rotating baffle is provided on the inner side of the limit baffle. A mold limiting slot is opened inside the rotating baffle. A mold lifting baffle is installed on the outer side of the limit baffle. An upper hydraulic mold is slidably installed on the inner side of the mold lifting baffle. A mold mounting block is provided on the outer side of the upper hydraulic mold. A mold counterweight is installed on the top of the upper hydraulic mold.

[0009] Preferably, the upper hydraulic chamber is movably connected to the rotating crossbeam via an upper adjusting screw, and the rotating crossbeam can drive the upper hydraulic chamber to rotate synchronously via the upper adjusting screw when rotating around the rotating adjusting column; When the rotating beam rotates, it can drive the upper hydraulic chamber to move above the lower tablet pressing mechanism via the upper adjusting screw. When the upper adjusting screw rotates, it can drive the upper hydraulic chamber to move up and down below the rotating beam.

[0010] Preferably, the exterior of the upper hydraulic mold is engaged with the rotating baffle outside the limiting baffle via a mold mounting block. When the mold mounting block rotates along the inner side of the limiting baffle, it can engage with the mold limiting slot inside the rotating baffle. When the mold mounting block moves up and down inside the limiting baffle, the mold lifting baffle can limit the movement trajectory of the mold mounting block. When the upper hydraulic mold moves up and down inside the upper hydraulic chamber, the exterior of the mold mounting block contacts the inner side of the limiting baffle. When the upper hydraulic mold moves up and down inside the upper hydraulic chamber, the exterior of the upper hydraulic mold contacts the mold lifting baffle.

[0011] Preferably, the lower tableting mechanism includes a hydraulic lifting mechanism, which is fixedly installed inside the processing table. The telescopic end of the hydraulic lifting mechanism is connected to a lifting adjustment cylinder. A support spring is installed inside the lifting adjustment cylinder. A connecting threaded cylinder is installed inside the lifting adjustment cylinder. A movable connecting block is slidably installed inside the lifting adjustment cylinder. A height limiting screw is installed inside the movable connecting block. A lifting limiting cylinder is installed inside the rotating adjusting column. An external hydraulic module is slidably installed inside the lifting limiting cylinder. An internal hydraulic module is connected to the top of the movable connecting block. A lifting push block is slidably installed inside the internal hydraulic module. The transmission telescopic plates are connected by telescopic plate springs.

[0012] Preferably, the top of the lifting adjustment cylinder is provided with a protrusion, and the lifting adjustment cylinder is slidably connected to the inside of the lifting limit cylinder through the protrusion at the top. The inside of the lifting adjustment cylinder is connected to the bottom of the movable connecting block through a support spring. When the hydraulic lifting mechanism extends or retracts, it can drive the lifting adjustment cylinder to move up and down. When the lifting adjustment cylinder moves up and down, it can drive the movable connecting block to move synchronously.

[0013] Preferably, the bottom of the height limiting screw passes through the movable connecting block and is connected to the internal thread of the connecting threaded cylinder, and the top of the movable connecting block is connected to the internal hydraulic module; When the height limiting screw rotates, it can drive the movable connecting block to move up and down inside the lifting and adjusting cylinder. When the movable connecting block moves up and down, it can drive the internal hydraulic module to move synchronously.

[0014] Preferably, the lifting and pushing block has a conical structure, the transmission telescopic plate is slidably installed inside the internal hydraulic module, the outside of the internal hydraulic module is in contact with the inside of the external hydraulic module, and the internal hydraulic module can be engaged with the bottom of the external hydraulic module through the transmission telescopic plate; When the lifting and pushing block moves downward, it can push the transmission telescopic plate to move to both sides. When the transmission telescopic plate moves to both sides, it can extend from the inside of the internal hydraulic module. When the transmission telescopic plate extends from the inside of the internal hydraulic module, the internal hydraulic module moves upward, which can drive the external hydraulic module to move upward synchronously. When the transmission telescopic plate moves to both sides, it can stretch the telescopic plate spring. The telescopic plate spring can drive the transmission telescopic plate to retract into the inside of the internal hydraulic module. When the transmission telescopic plate retracts into the inside of the internal hydraulic module, the internal hydraulic module can move upward independently.

[0015] The integrated automated processing technology of the hydraulic tablet press utilizes the aforementioned hydraulic tablet press.

[0016] Compared with the prior art, the present invention provides a hydraulic tablet press and its integrated automated processing technology, which has the following beneficial effects: 1. In this hydraulic tablet press, when the internal hydraulic module moves upward, if the lifting push block contacts the upper tablet pressing mechanism, the lifting push block moves downward inside the internal hydraulic module. When the lifting push block moves downward inside the internal hydraulic module, it can push the transmission telescopic plate to move to both sides. When the transmission telescopic plate moves to both sides, it can extend out from inside the internal hydraulic module. When the transmission telescopic plate extends, the internal hydraulic module moves upward, which can synchronously drive the external hydraulic module to move upward through the transmission telescopic plate. At this time, the upward movement of the external and internal hydraulic modules can drive the raw material to rise and cooperate with the upper tablet pressing mechanism to tablet the raw material. When the lifting push block does not contact the upper tablet pressing mechanism when the internal hydraulic module moves upward, the transmission telescopic plate retracts into the internal hydraulic module. At this time, the internal hydraulic module can move upward independently. When the internal hydraulic module moves upward independently, it can demold the tableted product. The tableting and demolding of the raw material are completed by the up and down movement of the internal hydraulic module, which can stably and cyclically complete the automated hydraulic tableting operation.

[0017] 2. This hydraulic tablet press can insert the upper hydraulic mold into the upper hydraulic chamber, causing the mold mounting block on the outside of the upper hydraulic mold to move upward through the gap between the rotating baffles. Then, the upper hydraulic mold is rotated, causing the mold mounting block on the outside of the upper hydraulic mold to engage with the rotating baffle. After the mold mounting block is engaged in the mold limiting slot, the lower tablet pressing mechanism moves upward and contacts the upper hydraulic mold, causing the upper hydraulic mold to move upward. When the upper hydraulic mold moves upward, the mold mounting block can move along the inside of the mold lifting baffle, thus enabling the upper hydraulic mold to be quickly replaced according to processing requirements.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a hydraulic tablet press and its integrated automated processing technology.

[0022] Example 1: Please see Figure 1 - Figure 12A hydraulic tablet press includes a processing table 1, a rotating adjusting column 2 installed on the top of the processing table 1, a rotating crossbeam 3 rotatably installed on the outside of the rotating adjusting column 2, an upper tablet pressing mechanism 6 connected internally to the rotating crossbeam 3, and a lower tablet pressing mechanism 7 installed inside the processing table 1. The lower tablet pressing mechanism 7 includes an external hydraulic module 78 and an internal hydraulic module 79, which are slidably connected. The internal hydraulic module 79 has a transmission telescopic plate 711 installed inside, and the internal hydraulic module 79 can drive the external hydraulic module 78 to move upward through the transmission telescopic plate 711. When the rotating beam 3 rotates around the rotating adjusting column 2, it can move the upper pressing mechanism 6 above the lower pressing mechanism 7. When the lower pressing mechanism 7 drives the internal hydraulic module 79 to move upward, the internal hydraulic module 79 contacts the interior of the upper pressing mechanism 6, which can drive the transmission telescopic plate 711 to extend. When the transmission telescopic plate 711 extends, the internal hydraulic module 79 moves upward, which can drive the external hydraulic module 78 to move synchronously. When the external hydraulic module 78 and the internal hydraulic module 79 extend into the interior of the upper pressing mechanism 6 and continue to move upward, they can perform pressing operations. When the internal hydraulic module 79 moves upward alone, it can drive the molded product to be demolded.

[0023] The top of the processing table 1 is equipped with a fixed limiting post 5, and the inside of the rotating beam 3 is provided with a limiting slot 4. When the rotating beam 3 rotates around the rotating adjusting post 2, it can be engaged with the outside of the fixed limiting post 5 through the limiting slot 4. The top of the processing table 1 is equipped with a robotic arm 8, and the top of the processing table 1 is equipped with a raw material rack 9.

[0024] During operation, the robotic arm 8 can tilt the raw materials on the raw material rack 9 onto the internal hydraulic module 79. Then, as it rotates around the rotating adjusting column 2, the rotating beam 3 rotates, causing the limiting slot 4 on the rotating beam 3 to engage with the fixed limiting column 5. After the limiting slot 4 engages with the fixed limiting column 5, the upper pressing mechanism 6 moves above the lower pressing mechanism 7. Then, the lower pressing mechanism 7 drives the internal hydraulic module 79 to move upward. After the lower pressing mechanism 7 moves upward and contacts the upper pressing mechanism 6, the internal hydraulic module 79 moves upward, which can drive the external hydraulic module 78 to move synchronously. When the internal hydraulic module 79 moves upward, it can drive the raw material to move synchronously. After the external hydraulic module 78 and the internal hydraulic module 79 drive the raw material into the upper pressing mechanism 6, the lower pressing mechanism 7 can cooperate with the upper pressing mechanism 6 to extrude and form the raw material. After the raw material is extruded and formed, the lower pressing mechanism 7 drives the internal hydraulic module 79 to move downward. When the internal hydraulic module 79 moves downward, the interior of the upper pressing mechanism 6 moves downward, and the upper pressing mechanism... When the internal part of the tableting mechanism 6 moves downward, it can push the external hydraulic module 78 downward. When the internal part of the upper tableting mechanism 6 moves downward, it can demold the tableted product from the internal part of the upper tableting mechanism 6. When the internal hydraulic module 79 moves downward, it can separate from the upper tableting mechanism 6. After the lower tableting mechanism 7 separates from the upper tableting mechanism 6, the upper tableting mechanism 6 can be moved away from the lower tableting mechanism 7 by rotating the rotating beam 3. Then the internal hydraulic module 79 moves upward. When the internal hydraulic module 79 moves upward and does not contact the upper tableting mechanism 6, the internal hydraulic module 79 no longer drives the external hydraulic module 78 to move. When the internal hydraulic module 79 moves upward alone, it can drive the tableted product to move upward, thereby separating the product from the lower tableting mechanism 7. When the internal hydraulic module 79 drives the product to move upward, the robotic arm 8 can remove the product from the internal hydraulic module 79. The tableting and demolding of the raw material are completed by the up and down movement of the internal hydraulic module 79, and the automated hydraulic tableting operation can be completed stably in a cycle.

[0025] Example 2: The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The upper tablet pressing mechanism 6 includes an upper adjusting screw 61. The outside of the upper adjusting screw 61 is threadedly connected to the inside of the rotating crossbeam 3. The bottom of the upper adjusting screw 61 is connected to an upper hydraulic chamber 62. A limit baffle 63 is fixedly installed inside the upper hydraulic chamber 62. A rotating baffle 64 is provided on the inner side of the limit baffle 63. A mold limiting slot 65 is opened inside the rotating baffle 64. A mold lifting baffle 66 is installed on the outside of the limit baffle 63. An upper hydraulic mold 67 is slidably installed on the inner side of the mold lifting baffle 66. A mold mounting block 68 is provided on the outside of the upper hydraulic mold 67. A mold counterweight block 69 is installed on the top of the upper hydraulic mold 67.

[0026] The upper hydraulic chamber 62 is movably connected to the rotating crossbeam 3 via the upper adjusting screw 61. When the rotating crossbeam 3 rotates around the rotating adjusting column 2, it can drive the upper hydraulic chamber 62 to rotate synchronously via the upper adjusting screw 61. When the rotating beam 3 rotates, it can drive the upper hydraulic chamber 62 to move above the lower tablet pressing mechanism 7 through the upper adjusting screw 61. When the upper adjusting screw 61 rotates, it can drive the upper hydraulic chamber 62 to move up and down below the rotating beam 3.

[0027] The exterior of the upper hydraulic mold 67 is engaged with the rotating baffle 64 outside the limiting baffle 63 via a mold mounting block 68. When the mold mounting block 68 rotates along the inner side of the limiting baffle 63, it can engage with the mold limiting slot 65 inside the rotating baffle 64. When the mold mounting block 68 moves up and down inside the limiting baffle 63, the mold lifting baffle 66 can limit the movement trajectory of the mold mounting block 68. When the upper hydraulic mold 67 moves up and down inside the upper hydraulic chamber 62, the exterior of the mold mounting block 68 contacts the inner side of the limiting baffle 63. When the upper hydraulic mold 67 moves up and down inside the upper hydraulic chamber 62, the exterior of the upper hydraulic mold 67 contacts the mold lifting baffle 66.

[0028] During operation, the upper hydraulic mold 67 can be inserted into the upper hydraulic chamber 62, causing the mold mounting block 68 on the outside of the upper hydraulic mold 67 to move upward through the gap between the rotating baffles 64. Then, the upper hydraulic mold 67 is rotated, causing the mold mounting block 68 on the outside of the upper hydraulic mold 67 to engage with the rotating baffles 64, preventing the upper hydraulic mold 67 from falling downward. Then, the upper hydraulic mold 67 is rotated again, causing the mold mounting block 68 to engage inside the mold limiting groove 65. After the mold mounting block 68 is engaged inside the mold limiting groove 65, the lower pressing mechanism 7 moves upward and contacts the upper hydraulic mold 67, causing the upper hydraulic mold 67 to move upward. When the upper hydraulic mold 67 moves upward, the mold mounting block 68 can move along the inside of the mold lifting baffle 66, thereby enabling the upper hydraulic mold 67 to be quickly replaced according to processing requirements.

[0029] Example 3: The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12The lower tablet pressing mechanism 7 includes a hydraulic lifting mechanism 71, which is fixedly installed inside the processing table 1. The telescopic end of the hydraulic lifting mechanism 71 is connected to a lifting adjustment cylinder 72. A support spring 73 is installed inside the lifting adjustment cylinder 72. A connecting threaded cylinder 74 is installed inside the lifting adjustment cylinder 72. A movable connecting block 75 is slidably installed inside the lifting adjustment cylinder 72. A height limiting screw 76 is installed inside the movable connecting block 75. A lifting limiting cylinder 77 is installed inside the rotating adjustment column 2. An external hydraulic module 78 is slidably installed inside the lifting limiting cylinder 77. An internal hydraulic module 79 is connected to the top of the movable connecting block 75. A lifting push block 710 is slidably installed inside the internal hydraulic module 79. The transmission telescopic plates 711 are connected by a telescopic plate spring 712.

[0030] The top of the lifting adjustment cylinder 72 is provided with a protrusion, and the lifting adjustment cylinder 72 is slidably connected to the inside of the lifting limit cylinder 77 through the protrusion at the top. The inside of the lifting adjustment cylinder 72 is connected to the bottom of the movable connecting block 75 through the support spring 73.

[0031] When the hydraulic lifting mechanism 71 extends or retracts, it can drive the lifting adjusting cylinder 72 to move up and down. When the lifting adjusting cylinder 72 moves up and down, it can drive the movable connecting block 75 to move synchronously.

[0032] The bottom of the height limiting screw 76 passes through the movable connecting block 75 and is connected to the internal thread of the connecting threaded cylinder 74, and the top of the movable connecting block 75 is connected to the internal hydraulic module 79. When the height limiting screw 76 rotates, it can drive the movable connecting block 75 to move up and down inside the lifting adjustment cylinder 72. When the movable connecting block 75 moves up and down, it can drive the internal hydraulic module 79 to move synchronously.

[0033] The lifting and pushing block 710 has a conical structure. The transmission telescopic plate 711 is slidably installed inside the internal hydraulic module 79. The outside of the internal hydraulic module 79 fits against the inside of the external hydraulic module 78. The internal hydraulic module 79 can be engaged with the bottom of the external hydraulic module 78 through the transmission telescopic plate 711. When the lifting push block 710 moves downward, it can push the transmission telescopic plate 711 to move to both sides. When the transmission telescopic plate 711 moves to both sides, it can extend from the inside of the internal hydraulic module 79. When the transmission telescopic plate 711 extends from the inside of the internal hydraulic module 79, the internal hydraulic module 79 moves upward, which can drive the external hydraulic module 78 to move upward synchronously. When the transmission telescopic plate 711 moves to both sides, it can stretch the telescopic plate spring 712. The telescopic plate spring 712 can drive the transmission telescopic plate 711 to retract into the inside of the internal hydraulic module 79. When the transmission telescopic plate 711 retracts into the inside of the internal hydraulic module 79, the internal hydraulic module 79 can move upward independently.

[0034] During operation, the height of the movable connecting block 75 can be adjusted by rotating the height limit screw 76 according to the weight of the raw material. Then, different internal hydraulic modules 79 can be replaced according to processing requirements. When the hydraulic lifting mechanism 71 extends, it can drive the lifting adjusting cylinder 72 to move upwards. When the lifting adjusting cylinder 72 moves upwards, it can drive the movable connecting block 75 to move upwards. When the movable connecting block 75 moves upwards, it can drive the internal hydraulic module 79 to move upwards inside the lifting limit cylinder 77. When the internal hydraulic module 79 moves upwards, if the lifting pushing block 710 moves upwards and contacts the upper pressing mechanism 6, the lifting pushing block 710 moves downwards inside the internal hydraulic module 79. When the lifting pushing block 710 moves downwards inside the internal hydraulic module 79, it can push the transmission telescopic plate 711 to move to both sides. When the transmission telescopic plate 711 moves to both sides, it can release the internal hydraulic module... The internal hydraulic module 79 extends outwards. When the transmission telescopic plate 711 extends, the internal hydraulic module 79 moves upwards, which can synchronously drive the external hydraulic module 78 to move upwards through the transmission telescopic plate 711. At this time, the upward movement of the external hydraulic module 78 and the internal hydraulic module 79 can drive the raw material to rise and cooperate with the upper tableting mechanism 6 to tablet the raw material. After the lifting push block 710 separates from the upper tableting mechanism 6, the telescopic plate spring 712 retracts, which drives the transmission telescopic plate 711 to retract into the internal hydraulic module 79. When the internal hydraulic module 79 moves upwards, the lifting push block 710 does not contact the upper tableting mechanism 6, and the transmission telescopic plate 711 retracts into the internal hydraulic module 79. At this time, the internal hydraulic module 79 can move upwards independently. When the internal hydraulic module 79 moves upwards independently, it can demold the tableted product, thereby completing the hydraulic tableting operation in a stable cycle.

[0035] Example 4: The integrated automated process for the hydraulic tablet press, using the hydraulic tablet press as described in Examples 1 to 3, includes the following steps: During operation, the raw materials on the raw material rack 9 are first poured onto the lower tableting mechanism 7 by the robotic arm 8. Then rotate the rotating beam 3 to move the upper tableting mechanism 6 above the lower tableting mechanism 7; The lower tableting mechanism 7 rises and cooperates with the upper tableting mechanism 6 to perform tableting operations; After tableting is completed, the lower tableting mechanism 7 moves downward, and the rotating beam 3 rotates, causing the upper tableting mechanism 6 to move away from the lower tableting mechanism 7. When the internal hydraulic module 79 moves upward, it separates the product from the lower tableting mechanism 7 and removes the product through the robotic arm 8.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
