Which nut to rotate when painting with a large flow rate?

The release agent is a functional substance between the mold and the finished product, the release agent has chemical resistance, the chemical composition of different resins is not dissolved when contacted, and the release agent also has heat resistance and stress resistance, which is not easy to decompose or wear; The release agent is bonded to the mold without being transferred to the processed workpiece, does not hinder painting or other secondary processing operations, and due to the rapid development of injection molding, extrusion, calendering, molding and other processes, the amount of release agent has also been greatly increased.

When the release agent is sprayed, it is very important to control the flow size of the release agent, the existing adjusting device is mostly manual adjustment, the machine needs to be stopped in the production process, and the adjustment area can only be entered after opening the safety door, and after a adjustment, it is also necessary to observe whether the adjustment amount is appropriate, if it does not reach the ideal value, it also needs to stop again, causes repeated adjustment, wastes time, seriously affects the utilization rate of equipment.

Technical Implementation Elements:

An object of the utility model is to provide a release agent spraying unit flow automatic adjustment device to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above purpose, the utility model provides the following technical scheme:

a release agent spraying unit flow automatic adjustment device, comprising supporting legs, a base, a controller, a high-pressure air storage tank and a guide rail support, the supporting legs are positioned below the base, the left end above the base is provided with a controller, the right end of the controller is provided with a high-pressure air storage tank, the top of the high-pressure air storage tank is provided with an electronically controlled flow valve that is electrically connected with the controller, the electronically controlled flow valve is connected with a conduit above, the conduit is provided with an energy storage tank above, and the right end of the energy storage tank is provided with a pressure sensor that is electrically connected with the controller, the other end of the conduit is communicated with the main connecting pipe, the main connecting pipe is fixed above the support, the support is fixed in the middle above the base, the main connecting pipe is provided with a plurality of outlets below, the first electric control valve, the second electric control valve and the third electric control valve connected with the controller are respectively arranged on the outlet, the first electric control valve, the second electric control valve and the third electric control valve are respectively connected with a plurality of jet pipes through a hose, the jet pipe is fixed on the baffle plate, and the baffle plate is fixed on the nut above the lead screw, The upper end of the lead screw is fixed on the bearing above the guide rail support, and the lead screw is connected with the motor through the partition plate below, and the motor is positioned below the guide rail support, and the guide rail support is positioned at the right end above the base.

Twist the mule at the top of the spray gun, decreasing clockwise and increasing counterclockwise.

What should I do if the nut can't rotate after the screw is painted?

You can only go in and out little by little and get the paint off.

Generally, the thread is according to the rule of the right hand, that is, the thumb points outward, and the direction of the other four fingers is the direction of rotation, which is applicable to nuts, bolts, and screws. To put it bluntly, it is loose clockwise and tight counterclockwise.

Loose on the left, tight on the right. Except in exceptional circumstances.

In the mechanical transmission mechanism, the lead screw nut is used

1) It can be the rotation of the lead screw to drive the moving parts to move in a straight line.

2) It can also be the linear motion of the moving parts driven by the rotation of the nut.

3) However, it cannot be reversed transmission, that is, the moving parts cannot move in a straight line to rotate the lead screw or nut.

In the case of ball screws, the moving parts can move in a straight line to rotate the screw or nut.

Therefore, the ball screw transmission system must have a braking or locking mechanism.
