Problems solved by technology

However, due to the influence of factors such as the structure of the extruder barrel, resistance, and material properties, the extrusion speed of the extrusion cylinder in the working state of the extruder cannot accurately reflect the extrusion speed of the product, and because the extrusion speed of the product Determines the quality of the product, the smoother the extrusion speed, the higher the quality of the product, so the existing technology cannot effectively improve the quality and extrusion efficiency of the extruded product

Embodiment 1

[0026] Embodiment 1: An automatic speed regulation and pressure control device for an extruder.

[0027] see figure 1 as shown, figure 1 For the use implementation scene diagram of the present invention, point out the installation position of each mechanism in this implementation scene:

[0028] A is the speed limit part placed on the main body of the extruder;

[0029] Part B is the pressure control and speed regulation part installed on the control seat of the extrusion machine. The right side of it is the PLC control cabinet in the control system. The microcomputer controller is installed in the PLC control cabinet. The microcomputer controller is connected with the brushless motor respectively. 6. The speed limit mechanism is electrically connected to the extruder speed limit mechanism.

[0030] see figure 2 and image 3 shown, where figure 2 for figure 1 The enlarged structure of A (speed limit part) in middle, image 3 It is the enlarged structure diagram of B ...

Embodiment 2

[0037] Example 2: A control method for an automatic speed regulation and pressure control device for an extruder

[0038] refer to Figure 4 As shown, a control method using the automatic speed regulation and pressure control device of the extruder in Embodiment 1 specifically includes the following steps:

[0039] S1. The extruder starts to move, and the speed measuring and limit mechanism of the extruder accurately measures the dynamic speed of the extruder, and then converts it into a pulse signal output and feeds it back to the microcomputer controller in the control system;

[0040] S2. The microcomputer controller in the control system adjusts the target motion speed parameters of the extruder by setting the parameters of each extrusion stage of the product according to the user, and then converts the target motion parameters into analog signals, and finally controls them in real time through the analog signals The movement speed and direction of the brushless motor;

Abstract

The invention discloses an automatic speed adjusting and pressure control device of an extruding machine. The automatic speed adjusting and pressure control device comprises a brushless motor drive mechanism, a speed measuring limiting mechanism of the extruding mechanism, speed limiting mechanisms, a synchronous belt deceleration mechanism and a control system, wherein a brushless motor is arranged at the empty area besides a pressure adjusting valve of the extruding machine and is connected with the pressure relief valve of the extruding machine through the synchronous belt deceleration mechanism; the speed limiting devices are arranged at both ends of a synchronous belt in the synchronous belt deceleration mechanism; the moving end of the speed measuring limiting mechanism of the extruding machine is connected with the moving part of the extruding machine. The invention also provides a control method. The automatic speed adjusting and pressure control device and the control method has the advantages that the dynamic speed of the extruding machine can be precisely measured through the speed measuring limiting mechanism of the extruding machine, and be converted into a pulse signal, and the pulse signal is fed back into a microcomputer control system; the movement speed and direction of the brushless motor are controlled in real time by setting the parameters in each extrudingphase of the product; the extruding speed and pressure automatic control can be realized, the uniformity in production of the products is guaranteed, and the qualified rate and production efficiencyof the product are improved.

Description

technical field [0001] The invention relates to the technical field of extruders, in particular to an automatic speed regulation and pressure control device and control method for an extruder. Background technique [0002] In the production of hot extrusion molding products such as welding wire and welding rod, the hot extrusion process is a very important production process, and the extrusion quality will directly affect the brittleness, toughness and strength of welding consumable products. [0003] In the extrusion production process of welding wire and welding rod, the process is mainly to put the heated blank into the mold of the extruder for extrusion. The extrusion speed and pressure of the press are extremely relevant, but the current extrusion speed, pressure and other parameters are all adjusted manually and empirically, which can easily cause inconsistencies in the product due to multiple extrusions, which is not consistent with an irregular extrusion resulting i...
