Problems solved by technology

[0004] In view of the shortcomings of low efficiency and insufficient destruction of the above-mentioned ordinary hammering, the rack-type pulverizer can fully crush the above-mentioned materials, but when it is used for materials with high toughness, strong strength or relatively wet materials, it is easy to cause jamming of the crushing head , causing the material to heat up sharply in a short period of time, the power consumption of the equipment is increased, and even the equipment is damaged. The invention provides a medicine crushing mechanism

Embodiment 1

[0025] like figure 1 and figure 2 As shown, a medicinal material crushing mechanism includes a cylindrical cylinder body 2, and a rotating shaft 9 connected with a driving motor is also arranged in the cylinder body 2, and the rotating shaft 9 is located in the center of the cylinder body 2, and also includes a pin Seat 3, pin 8 and crushing head 7, described pin seat 3 is fixedly connected with rotating shaft 9, and pin hole is all provided with on pin seat 3 and crushing head 7, and described pin 8 all forms gap fit with two pin holes or with one of them The pin hole is interference fit, and the other pin hole is clearance fit, and the length direction of the pin 8 is parallel to the axial direction of the rotating shaft 9, and the distance between the free end of the crushing head 7 and the axis center of the rotating shaft 9 is not greater than that of the cylinder 2 radius.

[0026] In this embodiment, in order to facilitate the replacement of crushing heads 7 of diffe...

Embodiment 2

[0028] This embodiment is further improved on the basis of embodiment 1, as figure 1 and figure 2 As shown, in order to reduce the stress of the crushing head 7 in the working process of the present invention and obtain more application points of the present invention to the material, so as to facilitate the structure of the crushing head 7, the strength design and the working efficiency of the present invention, the crushing There are more than one head 7, and each crushing head 7 is connected to the pin seat 3 by a pin 8.

Embodiment 3

[0030] This embodiment is further improved on the basis of embodiment 2, as figure 1 and figure 2 As shown, in order to evenly bear the force on each crushing head 7 and reduce the failure rate of the present invention, the crushing heads 7 are evenly distributed in a ring shape relative to the axis of the rotating shaft 9 .

[0031] Described pin seat 3 is made up of upper base plate and lower base plate parallel to each other, two ends are fixedly connected with upper base plate and lower base plate respectively, the upper base plate and lower base plate are all provided with pin holes, and upper base plate and lower base plate The pin holes are arranged in pairs, and the hollow area of ​​the sleeve is connected with the two end faces of the pin seat 3 .

[0032] The pin seat 3 of the above structural form is simple in structure, is convenient to obtain the pin seat 3 of less weight, is conducive to the starting of drive motor like this, and the sleeve that is provided wit...

Abstract

The invention discloses a medicine crushing mechanism. The medicine crushing mechanism comprises a barrel-shaped cylinder, wherein a rotating shaft connected with a driving motor is additionally arranged in the cylinder, and is positioned in the center of the cylinder; the medicine crushing mechanism further comprises a pin base, a pin and a crushing head; the pin base is fixedly connected with the rotating shaft; pin holes are formed in the pin base and the crushing head; the pin is in clearance fit with the two pin holes, or is in interference fit with one of the pin holes and in clearance fit with the other one of the pin holes; the length direction of the pin is parallel to the axial direction of the rotating shaft; and the distance from the free end of the crushing head to the axis of the rotating shaft is not greater than the radius of the cylinder. The medicine crushing mechanism is in favor of preventing the conditions of blockage of the crushing head in the operation process, influence on material properties due to acute heating of materials in a short time caused by excessive instant material output power and increment of power consumption of idle work of equipment or even equipment damage, and satisfies the crushing requirements of superfine materials.

Description

technical field [0001] The invention relates to the field of pharmaceutical processing powder prefabrication and waste product crushing processing equipment, in particular to a medicinal material crushing mechanism. Background technique [0002] In pharmaceutical manufacturing enterprises, unqualified drugs mainly come from the production process, drug inventory and return after sales; secondly, it also includes unqualified materials, unqualified raw and auxiliary materials, and raw and auxiliary materials that have exceeded the expiration date. Production enterprises must strictly follow the laws and regulations of the country and the provisions of the "Good Manufacturing Practice for Drugs" to treat unqualified products and production waste destructively before they can be treated as waste. [0003] In the destructive treatment of existing unqualified medicines, raw and auxiliary materials, and raw and auxiliary materials that have exceeded the expiration date, and in the ...
