Description

Technical Field

[0001] This utility model relates to the field of crushing mechanism technology, specifically an adjustable crushing mechanism for a tablet press. Background Technology

[0002] An adjustable crushing mechanism for a tablet press is typically designed to accommodate different materials and particle sizes. The main function of this mechanism is to crush larger pieces of material into a fineness suitable for tablet compression, while allowing the user to adjust the degree of crushing or particle size as needed.

[0003] Current crushing mechanisms are all of fixed size and cannot be adjusted to crush particles of a single size. They are limited in function and cannot meet current crushing needs, thus reducing their applicability. Therefore, we propose an adjustable crushing mechanism for tablet presses. Utility Model Content

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-5 As shown, this utility model discloses an adjustable crushing mechanism for a tablet press, including a crushing box 1. Mounting frames 2 are fixedly connected to both sides of the crushing box 1. A top cover 3 is detachably and movably connected to the top of the crushing box 1. A drive motor 4 is fixedly installed on one side of the mounting frame 2. Slide grooves 5 are provided on both sides of the crushing box 1. Moving plates 6 are slidably connected inside both slide grooves 5. Lead screws 7 are rotatably connected inside both slide grooves 5, and the outer periphery of the lead screws 7 is threadedly connected to the inner periphery of the moving plates 6. A power motor 8 is fixedly installed on one side of the moving plates 6. A fixing frame 9 is fixedly connected to one side of the outer periphery of the crushing box 1.

[0025] Among them, the output end of the power motor 8 passes through the moving plate 6 and is connected to the crushing roller 10, and the output end of the drive motor 4 passes through the crushing box 1 and is connected to the crushing roller 2 11.

[0026] The fixed frame 9 has a handle 12 on one side of its outer perimeter. The output end of the handle 12 passes through the fixed frame 9 and is fixedly connected to a rotating rod 13. Both sides of the rotating rod 13 are fixedly connected to bevel gears 14.

[0027] One end of each of the two lead screws 7 passes through the crushing box 1 and is fixedly connected to a bevel gear 15. The outer circumference of the bevel gear 15 meshes with the bevel gear 14. By setting a rotating handle 12, the rotating handle 12 drives the rotating rod 13 to rotate, which in turn drives the bevel gears 14 at both ends to rotate, so that the two lead screws 7 rotate synchronously and the moving plate 6 moves synchronously. This can ensure that the load is evenly distributed, avoid tilting or excessive pressure on one side, thereby protecting the equipment and improving working accuracy.

[0028] The inner wall of the crushing box 1 is fixedly connected to a fixed frame 16, the upper end of the fixed frame 16 is slidably connected to a filter frame 17, a rotating cover 18 is rotatably connected to one side of the crushing box 1, and a discharge port 19 is provided at the bottom of the crushing box 1. The rotating cover 18 facilitates the disassembly of the filter frame 17.

[0029] The top cover 3 is fixedly connected to the upper end of the feed port 20, and two limiting rods 21 are fixedly connected to both sides of the top cover 3. A slot 25 is opened on one side of the limiting rod 21.

[0030] The top of the crushing box 1 is fixedly connected to two sides of a fixing block 22. An L-shaped locking block 24 is slidably connected inside the fixing block 22 and engages with the slot 25. A return spring 23 is fixedly connected to one end of the L-shaped locking block 24 and the other end of the return spring 23 is fixedly connected to the inner wall of the fixing block 22. By setting the L-shaped locking block 24, by pulling the L-shaped locking block 24, the L-shaped locking block 24 can be released from the limiting position of the slot 25, which realizes the function of making it easy to remove the top cover 3, solves the problem of the inconvenience of cleaning the inside of the crushing box 1, and improves the convenience of cleaning.

[0031] Working principle: During use, rotating the handle 12 drives the rotating rod 13 to rotate, which in turn drives the bevel gears 14 at both ends to rotate, synchronously driving the bevel gears 15 to rotate, causing the two lead screws 7 to rotate synchronously, and the moving plate 6 to move synchronously. This ensures that the load is evenly distributed, avoids tilting or excessive pressure on one side, thereby protecting the equipment and improving working accuracy. This allows for adjustment of the distance between the first crushing roller 10 and the second crushing roller 11, thereby changing the crushed particle size and achieving the purpose of adjustable crushing degree. Pulling the rotating cover 18 and the filter frame 17 enables the function of filtering the crushed material and collecting the raw material inside the filter frame 17. By pulling the L-shaped locking block 24, the L-shaped locking block 24 compresses the return spring 23, causing the L-shaped locking block 24 to release the limit on the internal slot 25 of the limit rod 21, making it easy to remove the top cover 3. This solves the problem of the inconvenience of cleaning the inside of the crushing box 1 and improves the convenience of cleaning.
