ISO 23953-2 Horizontal Freezer Slide Lid Opening And Closing Testing Machine
System overview:
The horizontal freezer slide lid opening and closing test machine is designed and manufactured according to Chapter 5.3.3.2 of ISO 23953-2:2015(E) and customized requirements of customers. It is used for the opening and closing durability test of the horizontal freezer slide lid, also used for lid sliding actions during the energy efficiency performance test of the freezer. It is a dedicated fully automated testing equipment, which is suitable for testing departments such as testing and certification agencies, factory laboratories, etc.
This equipment adopts PLC intelligent control with mature technology, equipped with 2 sets of position-adjustable action actuators and mechanical fixture structures to clamp the handles on the surface of the freezer slide lids (also come with 2 sets of vacuum suction cups to meet the needs of different samples). At the same time, it is equipped with a color LCD touch screen as standard, which can preset the opening stroke, opening and closing speed, and opening pause time and interval time, so as to truly simulate the opening and closing of the freezer lid by hand, to achieve an intelligent control method, one machine with multiple functions.
Equipment principle:
Controlled by PLC, operated by intelligent touch screen, the servo motor drives the manipulators, and drives the clamp to hold the handle of the freezer lids (or vacuum suction cups to suck the surface of the freezer lids), so that it can open and close the lids in a reciprocating linear motion.

The structure of the testing machine as shown in the figure below, the overall frame structure is adopted, and the sample is placed on the bottom plate of the equipment, so that the relative movement is the internal stress, and the shaking of the equipment is reduced. Two column structures are installed on the bottom plate, and the each column contains one set of lid opening and closing mechanism as shown in Figure 1. At the same time, the freezer positioning fixture is installed on the bottom plate, which can clamp and fix the front, rear, left, right, and rear sides of the freezer.
