Example Embodiment

[0011] Further description will be made below with reference to the accompanying drawings and embodiments.

[0012] The method of adopting pre-compression on the rotary tablet press of the present invention is to add a pre-compression device in the compression mechanism of the rotary tablet press. That is, on the orbital disk of the rotary tablet press, a pre-pressing device is added behind the first filling device and the core-filling turntable, and before the second filling device, and the pre-pressing wheel (8) in the pre-pressing device is used to punch the nails The extrusion of (10) realizes the precise positioning of the chip, makes the radial position of the chip relatively fixed during the forming process, and improves the position accuracy of the chip.

[0013] The preloading device of the present invention is composed of preloading wheels, preloading wheel frames, fixing plates, adjusting screws, springs and other components. First put the copper sleeve (7) in the ...

Abstract

The present invention relates to a method for prepressing core tablet on the rotary core-covering tabletting machine and its device. It is characterized by that a prepressing device is added after first filling device and core-adding rotating disk and before second filling device so as to implement precompression location of core tablet and make the radial position of core tablet in the forming process be relatively fixed. Said prepressing device is formed from the components of prepressing wheel, prepressing wheel frame, fixed plate, regulating screw and spring, etc. The adoption of said method and device can ensure that the core tablet is positioned in the centre of medicine tablet so as to ensure the quality of core-covered tablet.

Description

1. Technical field [0001] The invention relates to a method and device for pre-pressing chips on a rotary core-coating tablet press. 2. Background technology [0002] In my country's pharmaceutical, chemical, food and other industries, solid powder with certain effects is usually filled into capsules to form capsule pills, or the solid powder is directly compressed into tablets to form tablets. People also often refer to the pharmaceutical machinery that compresses pharmaceutical tablets as tablet presses. In the past, the common tablets were single-color tablets made of one kind of powder. With the improvement of people's living standards, there have been two-color tablets made of two layers of powder of different colors on the market. A three-color tablet composed of three layers of powder of different colors, and a tablet in which another powder chip is wrapped in the middle of the second layer of powder layer, called package chip. The tablet press machine that produces...
