[0023] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0024] The following is in conjunction with the instruction manual appendix. Figure 1 To be continued Figure 5 The feeding and leveling mechanism of the tablet press of this utility model will be introduced.

[0025] The feeding and leveling mechanism of the tablet press of this utility model includes a base plate 10, a horizontal adjustment component, a feeding bracket 30, an up-down adjustment component, and a mounting plate 50; the mounting plate 50 is used to install the feeder 70; the horizontal adjustment component is disposed between the base plate 10 and the feeding bracket 30 to adjust the position of the feeding bracket 30 in the horizontal direction; the up-down adjustment component is disposed between the feeding bracket 30 and the mounting plate 50 to adjust the position and tilt angle of the mounting plate 50 in the vertical direction.

[0026] This invention utilizes a split-type adjustment mechanism design, breaking down complex spatial positioning into independent adjustments in two orthogonal directions, controlling horizontal displacement and vertical displacement / tilt angle separately, thus reducing operational difficulty. The horizontal adjustment component adjusts the position of the feeding bracket in the horizontal direction, while the vertical adjustment component integrates both height and tilt angle adjustment functions, simplifying the mechanism's complexity. The overall design achieves three-dimensional precise adjustment of the feeder's position, effectively solving the problems of cumbersome adjustments and insufficient precision in traditional mechanisms.

[0027] Furthermore, in some embodiments, the horizontal adjustment assembly includes a positioning base plate 21, a support base 22, a positioning element 23, an adjusting bolt 24, and a first locking element 25.

[0028] The positioning base plate 21 is located on the upper surface of the base plate 10 and its position on the upper surface of the base plate 10 can be adjusted. The adjusting bolt 24 is used to fix the positioning base plate 21, which has been adjusted to the position, on the upper surface of the base plate 10.

[0029] The feeding bracket 30 is fixedly connected to the bracket base 22, and the bracket base 22 is positioned on the upper surface of the positioning base plate 21 by the positioning member 23.

[0030] The first locking member 25 is used to fix the positioning base plate 21 and the bracket base 22.

[0031] During horizontal adjustment, first loosen the adjusting bolt 24 to move the positioning base plate 21 to the target position, then tighten the adjusting bolt 24 to complete the coarse adjustment; subsequently, the positioning component 23 achieves precise positioning of the support base 22, and finally, the first locking component 25 secures it. When disassembly is required, only the support base 22 needs to be removed. During reinstallation, there is no need to readjust the position of the positioning base plate 21; the positioning component 23 enables rapid positioning of the support base 22, thereby improving the adjustment efficiency of the feeding mechanism. The vertical adjustment components can be operated independently, achieving height and angle adjustments by changing the relative position of the mounting plate 50 and the feeding bracket 30. The modular design of the horizontal adjustment components allows for rapid restoration of the original positioning accuracy during disassembly and reinstallation, avoiding repeated adjustments.

[0032] This invention decomposes complex spatial positioning into independent adjustments in two orthogonal directions, reducing operational difficulty. The separate structure of the positioning base plate 21 and the support base 22 ensures both the horizontal adjustment range and the repeatability of positioning accuracy through the positioning component 23. The vertical adjustment assembly integrates both height and tilt adjustment functions, simplifying the mechanism's complexity. The overall design achieves three-dimensional precise adjustment of the feeder's 70° position, effectively solving the problems of cumbersome adjustments and insufficient precision in traditional mechanisms.

[0033] Furthermore, in some embodiments, the positioning substrate 21 has an adjustment hole 211 through which the adjustment bolt 24 passes, and the cross-sectional area of ​​the adjustment hole 211 is larger than the cross-sectional area of ​​the adjustment bolt 24 to adjust the position of the positioning substrate 21.

[0034] Specifically, the adjusting hole 211 can be designed as a circular, elliptical, or oblong through hole. The oblong through hole extends longer along the displacement direction of the positioning base plate 21 than it extends vertically; for example, the length dimension of the adjusting hole 211 is 0.5-2 mm larger than the bolt diameter. The adjusting bolt 24 can be a standard hexagonal head bolt or a special bolt with a flange. The bolt shank is clearance-fitted with the adjusting hole 211, with the clearance controlled within the range of 0.1-0.5 mm. As a preferred embodiment, a wear-resistant bushing can be provided on the inner wall of the adjusting hole 211. The bushing material can be brass or polytetrafluoroethylene (PTFE) to reduce frictional loss during the adjustment process.

[0035] This embodiment utilizes the dimensional difference between the adjusting hole 211 and the adjusting bolt 24 to create an adjustable gap structure. When the adjusting bolt 24 is loosened, the positioning base plate 21 can undergo a slight displacement along the extension direction of the adjusting hole 211 on the surface of the base plate 10. The displacement is limited by the dimensional difference between the adjusting hole 211 and the bolt. Specifically, the design that the size of the adjusting hole 211 is larger than the cross-sectional area of ​​the bolt ensures both the degree of freedom of adjustment and the positioning accuracy maintained by the final tightening of the bolt. This achieves stepless adjustment of the position of the positioning base plate 21, allowing for online adjustment without disassembling components while maintaining mechanical strength, significantly improving the convenience and accuracy of the leveling operation of the feeding mechanism.

[0036] Furthermore, in some embodiments, the support base 22 has a sink groove, the adjustment hole 211 is disposed at the bottom of the sink groove, and a support cover plate 221 is disposed in the sink groove to prevent external debris from entering the adjustment hole 211.

[0037] The recessed groove is a groove structure formed by a downward indentation on the surface of the support base 22, and its depth can be designed to be 5-15mm according to actual pollution prevention requirements. The support cover plate 221 is made of metal stamping or engineering plastic injection molding.

[0038] This embodiment utilizes the synergistic cooperation of the settling tank and the support cover plate 221 to form a three-dimensional protective structure. The depth design of the settling tank allows the adjustment hole 211 to be embedded in the bottom of the tank, creating a physical isolation space that effectively blocks horizontally splashed particles. The support cover plate 221 covers the opening of the settling tank, blocking vertically falling dust. Together, they form a double anti-contamination barrier, physically isolating the adjustment hole 211 from the external environment. Therefore, during continuous production of the tablet press, it prevents pharmaceutical powder, lubricants, and other production materials from entering the adjustment hole 211, ensuring that the adjustment bolt 24 is always in an operable state.

[0039] Furthermore, in some embodiments, the bracket cover 221 is provided with a through hole through which the first locking member 25 passes, so that the first locking member 25 presses the bracket cover 221 into the sink.

[0040] The through-hole can be circular, elliptical, or polygonal in shape, with circular through-holes being the easiest to manufacture and having the best compatibility with standard fasteners. The diameter of the through-hole needs to be slightly larger than the outer diameter of the first locking member 25 to allow for smooth passage, but the gap should be controlled within the range of 0.1-0.3 mm to avoid excessive offset. As a preferred embodiment, the edge of the through-hole can be chamfered to guide the smooth insertion of the first locking member 25. The first locking member 25 can be a locking handle with an external thread section, the external thread engaging with the threaded hole on the positioning base plate 21 to achieve locking.

[0041] The dual function is achieved through the synergistic action of the through hole and the locking element: After the horizontal adjustment assembly completes its positioning, the axial pressure generated when the first locking element 25 passes through the through hole causes the bracket cover plate 221 to fit tightly against the bottom surface of the settling tank, and the resulting friction effectively prevents the cover plate from shifting. At the same time, the design of the bracket cover plate 221 completely covering the adjustment hole 211 blocks the dust entry channel, thus integrating the dustproof function into the fixed structure. This reduces the number of parts and ensures the durability of the dustproof effect through the pre-tightening force of the locking element.

[0042] In other implementations, the support cover 221 can also be detachably connected to the settling tank via magnetic adsorption. Specifically, a permanent magnet is embedded at the bottom of the settling tank, and the support cover 221 is made of a magnetically conductive metal material.

[0043] Furthermore, in some embodiments, the positioning member 23 is fixed on the positioning base plate 21, and the support base 22 is provided with positioning holes that cooperate with the positioning member 23.

[0044] The positioning element 23 can be a mechanical positioning element with guiding function, such as a cylindrical pin, tapered pin, or diamond pin. The shape of the positioning hole matches the positioning element 23, such as a circular hole, tapered hole, or irregularly shaped hole. The fit between the positioning element 23 and the positioning hole can be a transition fit or a small clearance fit to ensure positioning accuracy. The fixing method of the positioning element 23 includes, but is not limited to, threaded connection, interference fit, or welding. The positioning hole can be set as a through hole or a blind hole, selected according to actual assembly requirements. The number of positioning elements 23 arranged on the positioning base plate 21 can be two or more, and they can be symmetrically distributed to improve positioning stability.

[0045] In this embodiment, a mechanical positioning structure is used to achieve precise positioning of the feeding bracket 30 and the positioning base plate 21. The cooperation between the positioning component 23 and the positioning hole establishes a reliable mechanical reference, effectively eliminating positional deviations during the horizontal adjustment process.

[0046] Furthermore, in some embodiments, the up-down adjustment assembly includes a second locking member 41 and an adjustment knob 42. The feeding bracket 30 has a threaded adjustment hole 211, and the adjustment knob 42 is threadedly engaged with the threaded adjustment hole 211. The adjustment knob 42 is located between the mounting plate 50 and the feeding bracket 30 to support the mounting plate 50. The adjustment knob 42 has a through hole through which the second locking member 41 passes. The second locking member 41 is used to lock the feeding bracket 30 and the mounting plate 50 after the adjustment knob 42 is adjusted to the correct position.

[0047] Specifically, the adjusting knob 42 can be a cylindrical structure with external threads, with a supporting surface at the top that contacts the mounting plate 50, and a threaded section at the bottom that mates with the threaded adjusting hole 211. A through hole extends axially through the adjusting knob 42, with a diameter slightly larger than the diameter of the second locking member 41 to allow free insertion. The threaded adjusting hole 211 can be a through hole with thread parameters matching the adjusting knob 42. The second locking member 41 is preferably a bolt or screw, with its threaded end forming a fastening connection with the threaded hole on the mounting plate 50. As a preferred embodiment, the outer periphery of the adjusting knob 42 can be provided with anti-slip texture to enhance operational convenience.

[0048] This embodiment achieves stepless precision adjustment of the height and tilt angle of the mounting plate 50 through a threaded transmission. The adjustment knob 42 serves both as a support and transmission mechanism. Rotating the adjustment knob 42 directly changes the support height of the mounting plate 50 due to its axial displacement. The through-hole design allows the second locking element 41 to simultaneously penetrate the feeding bracket 30 and the mounting plate 50, achieving three-point rigid fixation. This structure offers advantages such as continuous operation and precise positioning. Height adjustment can be completed with a single rotation. Furthermore, by appropriately setting the pitch of the adjustment knob 42, the height adjustment can be more precisely controlled by the number of rotations. After tightening with the locking element, a stable support is formed, effectively solving the problems of cumbersome procedures and low positioning accuracy inherent in traditional adjustment methods.

[0049] Furthermore, in some embodiments, the up-down adjustment assembly further includes a bracket bushing 43 through which the second locking member 41 passes, the bracket bushing 43 being elastic and disposed between the mounting plate 50 and the adjustment knob 42.

[0050] The bracket bushing 43 can be implemented in the following ways: it can be made of an elastic material such as polyurethane, rubber or silicone, with its inner diameter clearance fit with the second locking member 41 and its outer diameter interference fit with the contact surface of the mounting plate 50; or it can be made of an elastic washer structure composed of stacked metal spring sheets, with its axial compression controlled within the range of 0.5-2mm; or it can be set as a composite bushing with a bellows, the bellows part providing axial elasticity and the rigid end fitting against the plane of the adjusting knob 42.

[0051] In this embodiment, the intervention of the elastic support bushing 43 creates a controllable elastic interface between the adjustment knob 42 and the mounting plate 50. Specifically, during height or tilt adjustment, the support bushing 43 undergoes compressive deformation to absorb minor displacements of the adjustment knob 42, preventing localized stress concentration caused by rigid contact. In the locked state, the elastic restoring force of the bushing maintains uniform contact pressure between the mounting plate 50 and the adjustment knob 42, eliminating poor contact caused by manufacturing errors. This micro-displacement compensation mechanism achieved through elastic deformation effectively improves adjustment sensitivity and positioning stability.

[0052] Furthermore, in some embodiments, the up-down adjustment components are provided in at least two sets to adjust the position and tilt angle of the mounting plate 50 in the up-down direction.

[0053] Specifically, when adjusting the overall height of the mounting plate 50, all adjustment components can be adjusted simultaneously to the same height; when adjusting the tilt angle, the extension of each component can be adjusted differentially to achieve a predetermined tilt angle for the mounting plate 50. This embodiment significantly improves adjustment accuracy and stability, effectively eliminating the problem of mounting plate 50 misalignment caused by machining errors or assembly gaps. Through the rational configuration of the mechanical structure, both the convenience of adjustment operations and the ability to maintain the spatial position of the mounting plate 50 during operation are ensured, thereby meeting the high-precision requirements for the installation position of the feeder 70 in the tableting process.

[0054] Furthermore, in some embodiments, at least two sets of spaced-apart horizontal fixing components are also included for locking the mounting plate 50 in the horizontal direction.

[0055] Specifically, the horizontal fixing assembly includes a locking bolt 61 and an eccentric positioning post 62. The bottom of the mounting plate 50 is provided with a positioning groove 51. The eccentric positioning post 62 has an eccentric threaded hole that mates with the locking bolt 61. The axis of the eccentric threaded hole is offset from the axis of the eccentric positioning post 62 so that the outer peripheral surface of the eccentric positioning post 62 pushes against the groove wall of the positioning groove 51. The feeding bracket 30 has a through hole through which the locking bolt 61 passes. After the eccentric positioning post 62 is rotated into position, the locking bolt 61 is fixedly connected to the eccentric positioning post 62.

[0056] The eccentric positioning pin 62 can be cylindrical, and its outer circumferential surface in contact with the positioning groove 51 can be machined into an arc surface. The offset of the eccentric threaded hole can be designed to be 0.5-3mm according to the actual positioning accuracy requirements. The locking bolt 61 can be a hexagonal head bolt with a thread specification matching the eccentric threaded hole. The positioning groove 51 can be a through groove or a blind groove, with the groove width slightly larger than the diameter of the eccentric positioning pin 62 to allow for adjustment. As a preferred embodiment, the eccentric positioning pin 62 can be made of hardened steel to improve wear resistance, and its end can be provided with a wrench slot for easy rotation operation.

[0057] This embodiment achieves gapless positioning of the mounting plate 50 through a mechanical self-locking principle. When the outer circumferential surface of the eccentric positioning post 62 contacts the wall of the positioning groove 51, continued rotation generates a self-locking effect, and a rigid connection is formed by fixing it with the locking bolt 61. When multiple sets of horizontal fixing components work together, a uniformly distributed horizontal constraint force field can be constructed, effectively suppressing the vibration displacement of the mounting plate 50 during high-speed operation, ensuring stable positioning of the mounting plate 50 even under vibration conditions. This embodiment eliminates the need for additional positioning blocks and adjusting screws, simplifying the operation and improving positioning accuracy. Due to the self-locking characteristics of the eccentric structure, loosening of the connection is less likely to occur.

[0058] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
