Description

Technical Field

[0001] This utility model relates to a sliding damping device for guide rails in a hard capsule production line, belonging to the field of hollow capsule production equipment. Background Technology

[0002] In the production of hollow capsules, the sliding of the die strip within the guide rail is a crucial step. When the die strip collides with the front stop after sliding into position, it not only generates significant noise but also causes the die strip to bounce back, a problem that is particularly severe on high-speed production lines. This bounce not only leads to inaccurate positioning but also easily causes equipment malfunctions and downtime, seriously impacting production efficiency and product quality.

[0003] For example, noise and rebound issues: When the die strip collides with the front stop after sliding into position, it generates significant noise, and the die strip rebounds, especially on high-speed production lines where this problem is more severe. This rebound not only leads to inaccurate die strip positioning but can also cause equipment malfunctions and downtime, affecting production efficiency and capsule quality.

[0004] The influence of material properties and thickness: Stamped parts of different strengths, such as those ranging from ordinary sheet metal to high-strength sheet metal, have different yield strengths. The higher the yield strength of the sheet metal, the more prone it is to springback. Thick plate parts are generally made of hot-rolled carbon steel or hot-rolled low-alloy high-strength steel. Compared with cold-rolled thin sheet metal, hot-rolled thick plate metal has poorer surface quality, larger thickness tolerance, unstable material mechanical properties, and lower elongation. All of these factors affect the sliding and positioning accuracy of the die strip.

[0005] Part shape and blank holder force: The springback varies greatly depending on the shape of the part. Parts with complex shapes usually have an additional forming step to prevent springback due to incomplete forming. At the same time, adjusting the blank holder force is also crucial for controlling springback. Increasing the blank holder force allows for more complete drawing of the part, reducing the difference between internal and external stresses, thereby reducing springback. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this utility model provides a sliding damping device for guide rails in a hard capsule production line. The technical solution of this utility model is as follows:

[0018] This structure provides the following advantages:

[0019] Noise and rebound reduction: This device effectively reduces noise and rebound caused by the collision between the module strip and the front stop block at high speed through the action of the damper and the damping mechanism spring.

[0020] Improved positioning accuracy: Limiting the moving components with limit blocks ensures that the mold strip can stop precisely at the predetermined position, thus improving the positioning accuracy of the mold strip.

[0021] The moving assembly includes a moving plate 2, a damping limiting block 4, a damping block 11, and a slider 15. The damping block 11 is installed on the two arms at the front end of the moving plate 2, and the slider 15 is installed at the lower end of the moving plate 2. A guide rail 16 is installed on the support 1, and the slider 15 slides with the guide rail 16. The damping limiting block 4 is also installed at the lower end of the moving plate 2, and the damping limiting block 4 moves with the damping generating assembly.

[0022] The damping generating assembly includes a sleeve 5, a perforated pin 14, a damping limiting shaft 6, a damping limiting rocker arm 19, a bolt shaft 20, an adapter 21, a damping limiting spring 22, a turntable 23, and a toggle block 24. The sleeve 5 is installed at the bottom of the support 1, and the sleeve 5 is vertically oriented. The damping limiting shaft 6, coaxially arranged with the sleeve 5, is installed inside the sleeve 5 and slides with it. The upper end of the damping limiting shaft 6 extends to the upper part of the support 1 and moves with the damping limiting block 4. The damping limiting rocker arm 19 is mounted on the bolt shaft 20. The bolt shaft 20 is rotatably mounted on the adapter 21, which is mounted on the equipment. A hinge hole is provided on the damping limiting rocker arm 19, and a hinge shaft is provided at the lower end of the damping limiting shaft 6, which is slidably mounted in the hinge hole. A cam bearing 18 is installed at one end of the damping limiting rocker arm 19, and a reset assembly is provided between the other end and the support 1. A toggle block 24 is installed on the turntable 23, which periodically engages with the cam bearing 18 to drive the cam bearing 18. The turntable 23 is driven by a drive mechanism.

[0023] This structure provides the following advantages:

[0024] Precise control: Through the sliding engagement of sleeve 5 and damping limit shaft 6, precise control can be achieved on the sliding of damping limit shaft 6 within sleeve 5, thereby precisely controlling the sliding and stopping of the mold strip.

[0025] Dynamic fit: The dynamic fit design of the damping limit shaft 6 and the damping limit block 4 enables dynamic damping and limiting during the sliding process of the mold strip, improving the flexibility and accuracy of mold strip positioning.

The pin with a hole 14 limits the sliding stroke of the damping limiting shaft 6 in the sleeve 5.

[0029] The working principle of this utility model is as follows:

[0030] After the mold strip contacts the wear-resistant damping block 11, the slider 15 installed on the moving plate 2 slides backward on the guide rail 16. The damper 17 and the damping mechanism spring 7 generate a damping effect, and the mold strip moves backward to the position limited by the limit block 8. The damping limit block 4 and the damping limit shaft 6 are fastened together. The mold strip stops at the final position and performs a flipping action.

[0031] After the mold strip flipping action is completed, the drive mechanism (such as a drive motor) starts to drive the turntable 23 equipped with the toggle block 24 to rotate. The toggle block 24 lifts one end of the damping limit rocker arm 19 equipped with the cam bearing 18 and raises it. The damping limit shaft 6 slides down in the sleeve 5. The moving plate 2 moves forward under the action of the damper 17 and the damping mechanism spring 7. The damping limit block 4 and the damping limit shaft 6 disengage, completing one cycle of mold strip inertial force damping and damping recovery.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
