Description

Technical Field

[0001] This utility model belongs to the field of press technology, and in particular relates to a tablet press with uniform tablet thickness. Background Technology

[0002] In the industrial production field, powdered materials (such as chemical raw materials, food additives, pharmaceutical intermediates, etc.) often need to be compressed into tablet structures by tablet presses to reduce dust loss during transportation, increase bulk density, and facilitate subsequent storage, measurement and processing. Tablet presses are therefore widely used in many industries such as chemical, food and pharmaceutical, and are one of the key pieces of equipment connecting powdered raw materials and molded products.

[0003] Currently, most tablet presses on the market have significant shortcomings in meeting the forming needs of tablets of different thicknesses: the internal support structure of most tablet presses is fixed, and the material filling space in the mold cavity cannot be flexibly adjusted according to the actual tablet thickness required for production. They can only produce tablets of a single thickness specification. When it is necessary to switch to products of different thicknesses, the entire mold assembly needs to be replaced, which is not only cumbersome and time-consuming, but also increases the cost of mold procurement and maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a tablet press with uniform tablet thickness, which solves the problem that the internal support structure of the existing tablet press mold is fixed and cannot flexibly adjust the material filling space in the mold cavity to adapt to the production of tablets of different thicknesses.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a tablet press with uniform tablet thickness, comprising a housing, a base plate fixedly installed at the bottom of the housing, guide posts fixed at the top of the base plate near each corner, a support plate and a top plate slidably sleeved on the periphery of the guide posts from bottom to top, a pressure column fixedly through the center of the top plate, an electric heating plate embedded inside the pressure column, a mold plate slidably installed on the top of the support plate penetrating the housing, a cavity penetrating the mold plate, and an adjusting plate slidably installed inside the cavity below the pressure column.

[0007] The present invention is further configured such that guide grooves are provided on both inner sides of the cavity, and connecting blocks are fixed on both outer sides of the adjusting plate, and the connecting blocks are slidably engaged with the guide grooves.

[0008] The present invention is further configured such that two first screws penetrating the bearing plate are symmetrically fixedly installed on the top of the base plate, and the peripheral side of the first screws is threadedly connected to a limiting sleeve located below the bearing plate.

[0009] The present invention is further configured such that a plurality of support columns located below the adjustment plate are fixed on the top of the base plate, and the support columns are slidably engaged with the bearing plate.

[0010] The present invention is further configured such that two springs are sequentially sleeved on the periphery of the guide column, and the two springs are respectively located between the bottom plate and the bearing plate, and between the bearing plate and the top plate.

[0011] The present invention is further configured such that a second screw is rotatably mounted on the top of the pressure column, the second screw is threadedly connected to the outer shell, and a handle is fixed on the top of the second screw.

[0012] The present invention is further configured such that an arc-shaped plate located above the mold plate is fixedly installed on the top of the bearing plate, a guide plate penetrating the outer shell is fixed on one side of the bearing plate, and through slots are provided on both opposite outer sides of the outer shell.

[0013] This utility model has the following beneficial effects:

[0014] This invention allows for flexible adjustment of the height of the adjusting plate within the cavity by sliding the connecting blocks on both sides of the adjusting plate along the guide grooves on the inner wall of the cavity. This alters the material filling space to accommodate the production needs of tablets of different thicknesses, eliminating the need for complete mold assembly replacement and effectively reducing operational complexity and mold maintenance costs. Simultaneously, the limit for the downward movement of the bearing plate can be set by rotating the limiting sleeve on the first screw. Combined with the rigid support of the supporting column for the adjusting plate during tableting, this prevents changes in the cavity space caused by displacement of the bearing plate and adjusting plate under force, ensuring uniform material extrusion, effectively solving the problem of tablet thickness deviation, and improving the stability of tableting quality.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0026] Please see Figure 1-5 This utility model relates to a tablet press with uniform tablet thickness, comprising a housing 1, a base plate 2 fixedly installed at the bottom inside the housing 1, and guide posts 3 fixedly installed at the top of the base plate 2 near each corner. A support plate 4 and a top plate 5 are slidably fitted onto the sides of the guide posts 3 from bottom to top. A pressure post 6 is fixedly installed through the center of the top plate 5, and an electric heating plate (existing technology, not shown in the figure, and will not be elaborated upon here) is embedded inside the pressure post 6. A mold plate 7 penetrating the housing 1 is slidably installed on the top of the support plate 4, and a cavity 8 is formed through the mold plate 7. An adjusting plate 9 located below the pressure post 6 is slidably installed inside the cavity 8. The base plate 2 serves as a bottom support structure, providing stability for components such as the guide posts 3 and subsequent support posts 14. The installation base; the guide column 3 serves as a guide to ensure that the support plate 4 and the top plate 5 remain horizontal when moving up and down, avoiding deviation that could lead to uneven pressure during tableting; the support plate 4 supports the mold plate 7, while the top plate 5 fixes the pressure column 6, driving the pressure column 6 to perform a downward pressing action. The downward movement of the pressure column 6 applies pressure to the material in the cavity 8. The mold plate 7 can be slid out or pushed into the outer shell 1, facilitating the operator to fill materials and remove the formed tablets. The cavity 8 provides a forming space for the material. The adjusting plate 9 can slide within the cavity 8, and by adjusting its height, the filling space of the material in the cavity 8 can be changed, thereby meeting the pressing requirements of tablets of different thicknesses. The electric heating plate embedded inside the pressure column 6 can provide heating during the tableting process, helping the material to form better.

[0027] Furthermore, guide grooves 10 are provided on both inner sides of the cavity 8, and connecting blocks 11 are fixed on both outer sides of the adjusting plate 9. The connecting blocks 11 are slidably engaged with the guide grooves 10. The engaging structure of the guide grooves 10 and the connecting blocks 11 provides guidance and limit for the sliding of the adjusting plate 9 in the cavity 8, ensuring that the adjusting plate 9 remains horizontal when it moves, avoiding tilting that would cause uneven material distribution in the cavity 8, and thus ensuring uniform tablet thickness.

[0028] Two first screws 12, which penetrate the bearing plate 4, are symmetrically fixedly installed on the top of the base plate 2. The first screws 12 are threadedly connected to a limiting sleeve 13 located below the bearing plate 4. The first screws 12 provide the mounting base for the limiting sleeve 13. The limiting sleeve 13 can be adjusted up and down by rotating on the thread on the first screws 12, thereby limiting the downward movement height of the bearing plate 4. When the bearing plate 4 moves down with the mold plate 7 during the tableting process, the limiting sleeve 13 will prevent the bearing plate 4 from moving down further, thereby controlling the downward movement of the bearing plate 4.

[0029] Several support columns 14 are fixed on the top of the base plate 2, located below the adjusting plate 9. The support columns 14 slide through the bearing plate 4. Two springs 15 are sequentially sleeved on the sides of the guide column 3. The two springs 15 are located between the base plate 2 and the bearing plate 4, and between the bearing plate 4 and the top plate 5, respectively. In the non-pressing state, the springs 15 between the base plate 2 and the bearing plate 4 support the bearing plate 4 in a higher position. At this time, the top of the support column 14 does not extend out of the bearing plate 4 and does not contact the adjusting plate 9, so it does not affect the height adjustment of the adjusting plate 9. When the pressing operation is carried out, as the bearing plate 4 moves down with the mold plate 7, the top of the support column 14 will gradually extend out of the top surface of the bearing plate 4 until it contacts the bottom of the adjusting plate 9, forming a stable support. This prevents the adjusting plate 9 from moving down and causing the cavity 8 space to increase, ensuring that the material can be stably extruded and formed, and guaranteeing the pressing thickness. At the same time, after the pressing is completed, the springs 15 assist the bearing plate 4 to reset.

[0030] A second screw 16 is rotatably mounted on the top of the pressure column 6. The second screw 16 is threadedly connected to the outer shell 1. A handle 17 is fixed on the top of the second screw 16. The operator rotates the handle 17 to drive the second screw 16 to rotate synchronously. The threaded connection between the second screw 16 and the outer shell 1 converts the operator's rotational force into the up-and-down linear motion of the second screw 16. Since the second screw 16 is rotatably connected to the pressure column 6, when the second screw 16 moves down, it will push the pressure column 6 to move down synchronously, thereby driving the top plate 5 to move down along the guide column 3, realizing the downward pressing action of the pressure column 6 on the material in the cavity 8.

[0031] An arc-shaped plate 18 is fixedly installed on the top of the support plate 4 above the mold plate 7. A guide plate 19 is fixed on one side of the support plate 4, penetrating the outer shell 1. Through slots 20 are provided on both opposite outer sides of the outer shell 1. The arc-shaped plate 18 can limit the mold plate 7, preventing the mold plate 7 from tilting upward or shifting when sliding on the support plate 4, and ensuring the stability of the mold plate 7. The guide plate 19 extends outside the outer shell 1, making it convenient for the operator to place the mold plate 7 on the guide plate 19 and insert the mold plate 7 into the device. The through slots 20 facilitate the operator to rotate the limiting sleeve 13.

[0032] The operation process of this embodiment is as follows: First, the operator can rotate the limiting sleeve 13 on the first screw 12 through the through slot 20, and adjust the upper and lower positions of the limiting sleeve 13 according to the required tablet thickness to set the lower limit of the bearing plate 4; then, pull the guide plate 19 extending out of the outer shell 1, and slide the mold plate 7 on the top of the bearing plate 4 out of the outer shell 1 along the guide plate 19. Then, fill the material to be tableted into the cavity 8, and push the mold plate 7 back into the outer shell 1 along the guide plate 19 so that the cavity 8 is located directly below the pressure column 6; then, the operator rotates the handle 17 on the top of the second screw 16, which drives the second screw 16 to move down along the through threaded hole of the outer shell 1. The second screw 16 pushes the pressure column 6 to move down synchronously, and the pressure column 6 drives the top plate 5 to move down smoothly along the guide column 3. At the same time, the electric motor embedded inside the pressure column 6 is turned on. The hot plate heats the tablet. As the pressure column 6 continues to move downward, its bottom contacts the top of the mold plate 7 and drives the mold plate 7 and the support plate 4 to move downward simultaneously. At this time, the spring 15 between the bottom plate 2 and the support plate 4 is compressed. When the support plate 4 moves downward to contact the limiting sleeve 13, the support plate 4 stops moving downward. At this time, the top of the support column 14 extends out of the top surface of the support plate 4 and makes close contact with the bottom of the adjusting plate 9 to form support. The material in the cavity 8 is also formed under the squeezing action of the pressure column 6 and the adjusting plate 9. After the tablet is pressed, the handle 17 is rotated in the opposite direction to drive the second screw 16, the pressure column 6 and the top plate 5 to move upward and reset. The spring 15 between the bottom plate 2 and the support plate 4 rebounds and pushes the support plate 4 and the mold plate 7 to move upward and reset. Finally, the mold plate 7 is pulled out and the tablet formed in the cavity 8 is taken out, completing one tableting operation.
