Fixture for foaming of refrigerator box body

Abstract

The invention discloses a fixture for foaming of a refrigerator box body. The fixture includes a lifting transmission mechanism, a belt conveying mechanism, a supporting pipe mechanism, locking mechanisms, a turnover positioning mechanism, transmission limiting mechanisms and front baffle limiting mechanisms. The lifting transmission mechanism is internally provided with the belt conveying mechanism. The supporting pipe mechanism is arranged at the top of the belt conveying mechanism. The locking mechanisms are arranged on two sides of the lifting transmission mechanism correspondingly. The turnover positioning mechanism is arranged at the center of the top of the lifting transmission mechanism. The transmission limiting mechanisms are arranged on two sides of the turnover positioning mechanism, and the front baffle limiting mechanisms are arranged at the top and the bottom of the turnover positioning mechanism correspondingly. The lifting transmission mechanism, the belt conveying mechanism, the supporting pipe mechanism, the locking mechanisms, the turnover positioning mechanism, the transmission limiting mechanisms and the front baffle limiting mechanisms are combined to improvethe overall production efficiency and automation.

Description

technical field [0001] The invention relates to the technical field of foaming fixtures, in particular to a fixture for foaming a refrigerator box. Background technique [0002] Most of the existing lifting transmission mechanisms for foaming fixtures use hydraulic equipment as their power system, which has the problems of slow lifting speed, large instantaneous impact force during the lifting process, and poor transmission accuracy and stability. The foam box causes damage, and when it is installed and matched with the external frame, the overall loading and unloading operation is too cumbersome, and the space for loading other components is small, which easily interferes with the work of each component; [0003] The existing conveying mechanism for foaming fixtures only has a single conveying function, and cannot adjust the belt height for boxes with different shapes, which makes the compatibility and adaptability poor, and it is difficult to fit various processed products...

Problems solved by technology

[0002] Most of the existing lifting transmission mechanisms for foaming fixtures use hydraulic equipment as their power system, which has the problems of slow lifting speed, large instantaneous impact force during the lifting process, and poor transmission accuracy and stability. The foam box causes damage, and when it is installed and matched with the external frame, the overall loading and unloading operation is too cumbersome, and the space for loading other components is small, which easily interferes with the work of each component;

[0003] The existing conveying mechanism for foaming fixtures only has a single conveying function, and cannot adjust the belt height for boxes with different shapes, which makes the compatibility and adaptability poor, and it is difficult to fit various processed products the actual needs of

[0004] Most of the existing side plate support pipe structures used for foaming fixtures are flat plates. Although the production and installation of flat plates are relatively simple, their stress conditions during use are poor. are affected;

[0005] Most of the existing locking mechanisms for foaming fixtures are equipped with ball screws. Although ball screws have small friction and smooth motion during motion, they do not have self-locking functions, and are prone to The overall damage is caused by excessive force, and the manufacturing cost and replacement difficulty of the ball screw are high, and the existing locking mechanism for the foaming fixture cannot reduce the ball screw while ensuring the clamping effect. stress status;

[0006] Most of the mold replacement process of the existing foaming fixture needs to be shut down, disassembled, and then the overall mold replacement and installation operations are performed on it. The production efficiency is low, which affects the normal and fast operation of the entire production line, and various operations It is difficult to guarantee the safety at the time;

[0007] The locking and limiting process of the existing foam fixture is mostly based on the work of the parts corresponding to the individual control of each motor to clamp and cooperate the side plates, but it is difficult to achieve the effect of synchronous transmission and limit the use of the entire body. The precision of the matching transmission is low, and the production quality is affected;

[0008] Most of the front baffles of the existing foaming fixtures are fixed and cannot be adjusted according to actual needs, without any operating space, which limits the overall flexibility and layout, greatly affecting the overall transmission limit effect;
