Problems solved by technology

At present, the common locking devices in the film-making machinery market are usually made of hexagonal cone-end or flat-end set screws into ball-head screws, which are directly fastened in the groove of the middle die directly from the front of the die on the equipment. There is a point contact between the middle dies. When the gap between the middle die and the middle die hole on the turntable is large, it is easy to cause the axis of the middle die to not coincide with the axis of the middle die hole.

Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing.

[0011] Such as figure 1 , figure 2 As shown, the middle mold locking device includes a tightening rod 1, an outer screw 2, a guide key 3 and a connecting screw 4, wherein the head structure of the fixing rod 1 is made into a circular convex arc, and the outer screw 2 connects with the connecting screw 4. The tightening rod 1 is connected and fixed, and the guide key 3 is fixed on the tightening rod 1

[0012] When the middle mold locking device made according to the above structure is working, the locking device is put into the middle mold screw hole on the turntable, and the guide key 3 on the tightening rod 1 is embedded in the keyway in the middle mold screw hole, and rotates The outer screw 2 pushes the tightening rod 1 into the annular groove of the middle mold gradually and horizontally along the guide key 3, so that the annular convex arc at the front end of the t...

Abstract

The invention discloses a middle mold locking device. The middle mold locking device is used for solving the problem of suspension punching due to the fact that the axis of a middle mold in an existing tablet press structure is not coincided with the axis of a middle mold hole and an upper punching nail is not concentric with the middle mold hole. The middle mold locking device comprises a tightening rod, an outer screw, a guide key and a connecting screw, a head structure of the tightening rod is manufactured into an annular convex arc, the outer screw is connected with the tightening rod by the connecting screw, and the guide key is fixed onto the tightening rod. The middle mold locking device is mainly used on rotary tablet presses.

Description

technical field [0001] The invention relates to a locking device, in particular to a middle mold locking device on a tablet press. Background technique [0002] In my country's pharmaceutical, chemical, food and other industries, solid particles with certain effects are usually pressed into the shape of tablets. People often call the mechanical equipment that is pressed into tablets a tablet machine. The device is called the middle mold locking device. At present, the common locking devices in the film-making machinery market are usually made of hexagonal cone-end or flat-end set screws into ball-head screws, which are directly fastened in the groove of the middle die directly from the front of the die on the equipment. There is a point contact between the middle dies. When the gap between the middle die and the middle die hole on the turntable is large, it is easy to cause the axis of the middle die to not coincide with the axis of the middle die hole. . Therefore, it is ...
