Supporting and hoisting mechanism provided with sensor and used for mixing head in foaming machine

Abstract

The invention discloses a supporting and hoisting mechanism provided with a sensor and used for a mixing head in a foaming machine. The supporting and hoisting mechanism comprises a hard component conveying pipe installed on a supporting frame. The inner end of a supporting suspension arm of the supporting frame is hinged to a supporting stand column of the supporting frame. The hard component conveying pipe is arranged along the supporting suspension arm and is fixedly installed on the supporting suspension arm, and therefore the mixing head is supported and hoisted on the outer side of the supporting suspension arm. A piston rod of an air cylinder on the supporting stand column is hinged to the supporting suspension arm, can drive the outer end of the supporting suspension arm to rotate downwards when retracting inwards and can drive the outer end of the supporting suspension arm to rotate upwards until the supporting suspension arm is located horizontally when stretching outwards; a temperature sensor is installed on an installation pipe of the hard component conveying pipe; the supporting stand column is provided with a rotating mechanism. The supporting and hoisting mechanism has the advantages that the pouring height and the horizontal position of the mixing head can be conveniently adjusted, and the temperature of polyurethane foaming material in the mixing head can be accurately obtained.

Description

technical field [0001] The invention relates to the technical field of polyurethane foam production equipment, in particular to a supporting and hoisting mechanism for a mixing head in a high-pressure polyurethane foaming machine. Background technique [0002] The function of the mixing head in the polyurethane foam machine is to pour the polyurethane foam raw material into the mold. The mixing head is connected with a component conveying hard pipe connected to the polyurethane foam raw material barrel. The supporting and hoisting mechanism of the mixing head in a traditional polyurethane foaming machine includes: a support frame, and the component conveying hard pipe is fixedly installed on the support frame so that Hang the mixing head support above the mold outside the support frame. The supporting and hoisting mechanism of the mixing head in the traditional polyurethane foaming machine has the following defects: 1. After the component conveying hard pipe is fixedly inst...

AI Technical Summary

Problems solved by technology

The supporting and hoisting mechanism of the mixing head in the traditional polyurethane foaming machine has the following defects: 1. After the component conveying hard pipe is fixedly installed on the support frame, the pouring height of the mixing head is fixed. When the pouring height needs to be adjusted during the production process, it needs to The mixing head can be adjusted to the position corresponding to the required pouring height only by replacing the component conveying hard pipe of the corresponding length, which not only takes time and effort, but also increases the production cost; The barrel to the mixing head needs to go through a long section of tube, which makes the parameters of the polyurethane foaming raw material in the mixing head, such as temperature and pressure, different from those in the polyurethane foaming raw material barrel, resulting in the polyurethane foaming raw material in the mixing head Parameters such as temperature and pressure are difficult to be grasped in a timely and accurate manner
