The diversity of the structure of the tablet press

The diversity of the structure of the tablet press

According to the analysis of Guangdong Richpacking, in the customized orders of users, the diversified requirements on the structure are mainly reflected in the following aspects:

(1) in terms of the way of film production, it is required to produce films on one side and on both sides, which can produce films on one side and on both sides. This requires the design and transformation of the extruder structure to achieve different requirements.

(2) in terms of protection, it is required to have a breaking-off protection structure and automatic power off protection when opening the pressure chamber door. 1) broken impact protection structure is when punch in sudden rupture accident case, fault protection system rapid response and equipment automatic stop immediately, to prevent the occurrence of safety accidents, to eliminate hidden dangers in the bud; 2) when you start the tablet room door tablet automatic power-off protection refers to the open room door, tablet machine is not running, the tablet press under the condition of normal operation, the tablet room door open, will automatically stop quickly. This requires both mechanical and electrical parts of the design transformation, detection signal to the electrical control system to achieve automatic protection control.

(3) special requirements on the structure and materials of some parts. For example, some users of tablet products have anti-explosion requirements, pressure chamber doors are required to adopt stainless steel materials, strong durability and corrosion resistance beautiful; The feeding device is made of bakelite material to avoid interaction with the material.

(4) in terms of operation control, the operating system of most tablet presses is integrated with the host machine, but some require the operating system to be independent and operate at a distance. According to user requirements for electrical design innovation of operating system, independent electrical cabinet design processing, operating system and independent electrical cabinets, together with engine cable connection, thus to realize the remote control operation.

2. Analysis of the structure and operation requirements of the tablet press with special requirements

The structure of the tablet press with special requirements has its own specific features, and the use requirements also need to be paid attention to. The following parts are analyzed and introduced from several common models.

2.1 analysis of the structure and operation requirements of the tablet press using the special-shaped punch

In the process of pressing, the tablet with different type of die pressing has definite positioning requirements for the die, such as square, trapezoid, triangle, ellipse, polygon and other non-circular shapes. Demand for tablet machine structure is mainly the turret punch holes machining keyway (to rush on to pole position), the requirement of die is in par with directional keys, so during the installation can match the and turret punch holes. In the process of pressing the lower punch, the hole in the middle die is never separated from the lower punch, and its positioning and coordination are clear, so no special processing is required.

When using different die pressing tablets, punch in the punch hole positioning can't free rotation, can only do lifting movement up and down along the guide rail, at the same time in the rotary table drive and the guide rail sliding friction, thus deepening the push rod and the guide rail wear and punch and rotary table wear and tear. Therefore, in the use of the process, very attention should be paid to the lubrication of the hedging rod and guide rail, forming a daily maintenance system; Punch button will check regularly, if loose button will cause the key and keyway and punch and punch hole wear, impact punch to the positioning requirement of the mould, serious will damage the punch and the die and can't normal production.

When installing the special-shaped punch, the first thing to do is to make the punch rod and the middle die accurately positioned. After the punch rod enters the middle die freely, the top wire of the middle die is tightened to prevent the "bite" of the rod and the middle die caused by improper positioning. After the completion of all the die installation, apply the hand wheel car for several rounds, no abnormality, and then turn on the power to run.
