[0011] Beneficial effects

[0012] This invention provides an automatic anti-sticking demolding device for tablet presses. It offers the following advantages: Through the cooperation of the demolding assembly, mounting ring, and inner membrane, after the material in the lower mold is pressed, a pump body inflates the lower mold through a distribution pipe.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In actual use, because aquatic raw materials are rich in protein and water and are sticky, they are very easy to stick to the mold surface during the pressing process. This makes it inconvenient to demold and can easily lead to damage.

[0022] In view of this, the present invention provides an automatic demolding device for tablet presses to prevent sticking, which solves the problem that in actual use, aquatic raw materials are rich in protein and water and have stickiness, and are very easy to stick to the surface of the mold during the pressing process, which makes demolding inconvenient and prone to damage.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: By Figure 1-5It is known that an automatic demolding device for preventing sticking in a tablet press includes a worktable 1. A lower mold 2 is fixedly connected to the top of the worktable 1. An upper mold 3 is provided above the lower mold 2. A mounting frame 7 is installed on the top of the upper mold 3. The bottom of the mounting frame 7 is fixedly connected to the top of the worktable 1. The automatic demolding device for preventing sticking in a tablet press also includes a demolding component 4, a lifting device 5, and a limiting device 6. The demolding component 4 is installed at the bottom of the lower mold 2; the lifting device 5 is installed at the top of the upper mold 3; and the limiting device 6 is installed between the upper mold 3 and the lifting device 5. The lower mold 2 is demolded by the demolding component 4, the lifting device 5 drives the upper mold 3 to press the lower mold 2, and the limiting device 6 fixes the upper mold 3.

[0025] In the specific implementation process, it is worth noting that the lower mold 2 and the upper mold 3 are used in combination, and the upper mold 3 is supported by the mounting bracket 7. After the stamping is completed, the demolding component 4 can quickly push out the material in the lower mold 2, thereby avoiding the problem of inconvenience in demolding the material. During the stamping process, the lifting device 5 is used to drive the upper mold 3 to stamp the lower mold 2, ensuring that the stamped material is stably formed. When cleaning or replacing the upper mold 3, it is replaced by the limiting device 6.

[0026] Furthermore, the demolding assembly 4 includes a retaining ring 41, an inner membrane 42, a diverter pipe 43, a mounting ring 44, a pump body 45, and a protective device 46. The retaining ring 41 is threadedly connected to the inner wall of the lower mold 2; the inner membrane 42 is fixedly connected to the bottom of the retaining ring 41 and abuts against the inner wall of the lower mold 2; the diverter pipe 43 is connected to the bottom of the lower mold 2; the mounting ring 44 is fixedly connected to the outer wall of the diverter pipe 43, and the outer wall is threadedly connected to the bottom of the worktable 1; the pump body 45 is connected to the end of the diverter pipe 43; and the protective device 46 is installed on the outer wall of the diverter pipe 43. Through the cooperation of the retaining ring 41 and the inner membrane 42, the pump body 45 and the diverter pipe 43 demold the lower mold 2, the mounting ring 44 fixes the diverter pipe 43, and the protective device 46 protects the diverter pipe 43.

[0027] In the specific implementation process, it is worth noting that the outer wall of the fixing ring 41 is provided with threads, which can be fixed to the mold groove opened at the top of the lower mold 2, and the inner membrane 42 at its bottom will adhere to the inner wall of the mold groove. In this way, the material is stably formed when the upper mold 3 is stamping. Moreover, the inner membrane 42 itself has good deformation internal force, but its outer wall is tightly attached to the inner wall of the mold groove. When it is squeezed by the upper mold 3, the inner membrane 42 will not deform due to the restriction of the mold groove. Furthermore, the diversion pipe 43 is fixed to the bottom of the workbench 1 under the support of the mounting ring 44. In this way, when the pump body 45 inflates the lower mold 2 through the diversion pipe 43, the air pressure will squeeze the bottom of the inner membrane 42. As the air pressure continues to increase, it will cause the inner membrane 42 to change, squeezing out the material inside, thereby completely demolding. Since the pressure increases steadily, the material will not be damaged during demolding. In addition, the inner membrane 42 will not deform under the protection of the protective device 46 during stamping.

[0028] Furthermore, the protection device 46 includes a valve 461 and a sealing gasket 462. The valve 461 is installed on the side of the diversion pipe 43 near the pump body 45. The sealing gasket 462 is sleeved on the outer wall of the diversion pipe 43 and abuts against the mounting ring 44 and the lower mold 2. The valve 461 restricts the air pressure in the diversion pipe 43, and the sealing gasket 462 seals the space between the diversion pipe 43 and the lower mold 2.

[0029] In the specific implementation process, it is worth noting that the sealing gasket 462 is made of rubber. Under the compression of the mounting ring 44 and the lower mold 2, it can prevent leakage between the diversion pipe 43 and the lower mold 2. The valve 461 will close the diversion pipe 43 when the upper mold 3 presses the lower mold 2, thereby stabilizing the air pressure between the inner membrane 42 and the diversion pipe 43 and preventing deformation under the pressure of the upper mold 3, thus protecting the inner membrane 42.

[0030] Example 2: From Figure 1-5 It is known that the lifting device 5 includes a mounting plate 51, a threaded rod 52, a threaded cylinder 53, a transmission gear 54, and a servo motor 55. The mounting plate 51 is mounted on the top of the upper mold 3 and sleeved on the outer wall of the mounting frame 7. The threaded rod 52 is fixedly connected to the top of the mounting plate 51. The threaded cylinder 53 is threadedly connected to the outer wall of the threaded rod 52, and the outer wall is rotatably connected to the inner wall of the mounting frame 7 through a sealed bearing. The transmission gear 54 is meshed with the outer wall of the threaded cylinder 53. The conveying end of the servo motor 55 is fixedly connected to the outer wall of the transmission gear 54, and the outer wall is fixedly connected to the top of the mounting frame 7. Through the cooperation of the threaded cylinder 53 and the transmission gear 54, the servo motor 55 drives the threaded rod 52 to rotate, which causes the mounting plate 51 to move the upper mold 3.

[0031] In the specific implementation process, it is worth noting that the inner wall of the threaded cylinder 53 is provided with the same internal thread as the outer wall of the threaded rod 52, and the transmission gear 54 is a bevel gear. The top of the threaded cylinder 53 is provided with the same bevel gear, and the bottom of the threaded rod 52 is fixed to the top of the mounting plate 51. Therefore, when the servo motor 55 drives the transmission gear 54 to rotate, the transmission gear 54 will mesh with the threaded cylinder 53. The inner wall of the threaded cylinder 53 is also threadedly connected to the threaded rod 52. Therefore, when the threaded cylinder 53 rotates, the threaded rod 52 will rise and fall inside it, driving the mounting plate 51 and the upper die 3 to press the material in the lower die 2.

[0032] Furthermore, the limiting device 6 includes an insert block 61, a locking block 62, and a fixing plate 63. The insert block 61 is fixedly connected to the top of the upper mold 3 and inserted into the inner wall of the mounting plate 51; the locking block 62 is inserted into the inner wall of the insert block 61; the fixing plate 63 is fixedly connected to the side of the locking block 62 away from the locking block 62 and is slidably locked into the top of the mounting plate 51; wherein, through the cooperation of the insert block 61 and the locking block 62, the fixing plate 63 fixes the upper mold 3.

[0033] In the specific implementation process, it is worth noting that the top of the side of the locking block 62 near the insert block 61 is sloping. When installing the upper mold 3, push the fixing plate 63 so that the locking block 62 is inserted into the opening in the side wall of the insert block 61 and locked in the inner wall of the insert block 61. In this way, the insert block 61 is fixed on the mounting plate 51 and the upper mold 3 is fixed at the bottom of the mounting plate 51, making it convenient for replacement and cleaning.

[0034] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
