Description

Technical Field

[0001] This invention relates to the field of slide durability testing equipment, and more particularly to a self-weight slide durability testing device with ambient temperature simulation. Background Technology

[0002] Gravity-controlled slides utilize the weight of the items themselves to automatically slide them, thus achieving automated inventory management without the need for any power drive device. Automated slides are widely used in smart cabinets, display cases, and automated production lines. However, with prolonged use, gravity-controlled slides often experience fatigue wear and jamming.

[0003] Currently, in high and low temperature display cases or automated production lines for high and low temperature products, the hardness and elasticity of the self-weight slide materials used are affected by temperature, which greatly shortens their service life and affects the normal use of the system. Summary of the Invention

[0004] As mentioned above, the industry currently lacks dedicated testing equipment for accelerated durability verification of self-weight slides under set high and low temperature conditions, making it impossible to assess their lifespan and reliability under real-world temperature conditions in advance. Therefore, this invention provides a self-weight slide durability testing device with ambient temperature simulation. This invention primarily utilizes a temperature control system to reproduce high and low temperature conditions within a cabinet. A piston cylinder and piston rod alternately raise and lower the two ends of the slide detection groove, causing the tested self-weight slide within the mold to slide back and forth along the detection groove under the influence of gravity. This achieves the effect of accelerating the assessment of the self-weight slide's durability performance under simulated real-world temperature conditions, exposing fatigue wear and potential jamming hazards in advance, and ensuring long-term reliable operation in high and low temperature application scenarios.

[0008] Furthermore, the temperature control system includes a cooling module and a heating module for controlling the temperature of the internal cavity space of the cabinet.

[0010] Furthermore, the heating module has at least two heating tubes; the heating tubes are located on the top of the rear wall of the cabinet cavity, and hot air is sent to the airflow circulation duct by a fan to raise the temperature.

[0011] Furthermore, the bottom outlet of the evaporator is connected to the forced evaporation box via a connecting pipe, so that the condensate generated by the evaporator during the cooling or defrosting stage is introduced into the forced evaporation box; the forced evaporation pipe is the refrigerant pipeline between the compressor outlet and the condenser inlet; a section of the forced evaporation pipe is coiled into the forced evaporation box.

[0012] Furthermore, the top of the ventilation baffle is connected to the swivel blade fan plate; the ventilation baffle is provided with a number of ventilation holes.

[0035] The slide track durability testing mechanism 2 includes: a base 201, a bracket 202, a slide track testing groove 203, a roller 204, a testing mold 205, a piston cylinder 206, a piston rod 207, and a guide head 208.

[0036] The base 201 is fixed to the top of the electrical control box 9; the bracket 202 is fixed to the inner wall of the base 201; the base 201 and the bracket 202 form a rigid frame; the bottom central shaft of the slide detection groove 203 is fixedly connected to the base 201 through rollers 204; the piston cylinder 206 is fixed to both sides of the inner wall of the bracket 202; the piston cylinder 206 and the piston rod 207 are oscillatingly floating; the head of the piston rod 207 is provided with a guide head 208; the guide head 208 abuts against the top surface of the two side wall panels of the slide detection groove 203, and pushes the wall panels within the extension and retraction stroke of the piston rod 207, causing the slide detection groove 203 to swing back and forth around the horizontal transverse axis, thereby causing the tested self-weight slide placed in the test mold 205 to slide back and forth along the slide detection groove 203 under the action of gravity component, and to perform durability testing.

[0037] The temperature control system includes a cooling module and a heating module, used to control the temperature of the internal space of the cabinet 1.

[0038] The refrigeration module is a medium-temperature refrigeration module, with an adjustable temperature of -2℃ to 4℃.

[0039] The refrigeration module includes: a condenser 3, an evaporator 301, a compressor 302, a forced evaporation pipe 303, and a forced evaporation box 304; the compressor 302, the condenser 3, and the evaporator 301 are connected by pipes; the condenser 3 and the compressor 302 are fixed to the top outer wall of the cabinet 1; the evaporator 3 is suspended in the center of the top wall of the inner cavity of the cabinet 1; the evaporator 3 sends cold air to the airflow circulation duct 11 through the fan 7 for cooling.

[0040] The heating module has at least two heating tubes 4; the heating tubes 4 are located on the top of the rear wall of the inner cavity of the cabinet 1, and hot air is sent to the airflow circulation duct 11 by the fan 7 for heating. The air is rapidly heated as it flows through the high-temperature heating tubes 4, forming hot air.

[0041] The bottom outlet of the evaporator 301 is connected to the forced evaporation box 304 via a connecting pipe, so that the condensate generated by the evaporator 301 during the cooling or defrosting stage is introduced into the forced evaporation box 304; the forced evaporation pipe 303 is the refrigerant pipeline between the outlet of the compressor 302 and the inlet of the condenser 3; a section of the forced evaporation pipe 303 is coiled into the forced evaporation box 304; the forced evaporation box 304 is located on the top of the rear side wall panel of the cabinet 1.

[0042] The forced evaporator tube 303 first enters the forced evaporator box 304 in the form of a coil for subcooling, thereby improving refrigeration efficiency and reducing the inconvenience of system drainage.

[0043] The bottom outlet of the evaporator 301 is connected to the forced evaporation box 304 via a connecting pipe, which is used to guide the condensate generated by the evaporator 301 during the refrigeration or defrosting stage into the forced evaporation box 304; the forced evaporation pipe 301 is the refrigerant pipeline between the outlet of the compressor 302 and the inlet of the condenser 3; a section of the forced evaporation pipe 301 is coiled inside the forced evaporation box 304, so that its outer surface is in direct contact with the condensate, so as to use the residual heat of the refrigerant to evaporate the condensate, while reducing the superheat of the refrigerant 32 and improving the system energy efficiency.

[0044] The top of the ventilation baffle 6 is connected to the swivel blade fan plate 5; the ventilation baffle 6 is provided with a number of ventilation holes.

[0045] The fan 7 is used to draw in the air from the slide durability test chamber below the oscillating blade fan plate 5 and force it to blow over the surface of the evaporator 301 or the heating tube 4.

[0046] Example 1 This embodiment addresses the current industry problem of a lack of dedicated testing equipment for accelerated durability verification of self-weighted slides under set high and low temperature conditions, thus preventing the early assessment of their lifespan and reliability under real-world temperature conditions. Therefore, the following solution is disclosed; please refer to the details. Figure 1-8 As shown, it includes: a temperature control system; When the heating module is used to provide a high-temperature simulation environment, the heating tube 4 is turned on and blown by the fan 7 towards the heating tube 4. The air is rapidly heated as it flows through the high-temperature heating tube 4. The heated air is then circulated through the airflow circulation duct 11 to form hot air, and circulates in the inner cavity of the cabinet 1 through the sway vane 5 and the ventilation baffle 6, thereby making the temperature of the entire environment rise evenly.

[0047] Example 2 This embodiment is based on Embodiment 1, such as... Figure 1-8 As shown: When the refrigeration module is used to provide a low-temperature simulation environment, after the compressor 302 starts, it discharges high-temperature and high-pressure refrigerant. The refrigerant first enters the condenser 3 through the forced evaporation pipe 303 to release heat and condense. After being depressurized by the throttling element, it flows into the evaporator 301 suspended in the center of the top wall of the inner cavity of the cabinet 1 to absorb heat and evaporate. Under the action of the fan 7, the evaporator 301 sends the generated cold air evenly downward into the inner cavity of the cabinet 1 along the airflow circulation duct 11, so that the temperature of the inner cavity drops rapidly to the set medium temperature range (-2℃~4℃). At the same time, the condensate flows into the forced evaporation box 304 and is instantly evaporated by the high-temperature forced evaporation pipe 303, realizing continuous refrigeration operation with no residual water and high energy efficiency.

[0048] Example 3 This embodiment is based on embodiment two, such as... Figure 1-8 As shown: Simultaneously, the air pump 10 is controlled by the electronic control system to add air to the piston cylinder 206, driving the piston rod 207 to extend and retract. The guide head 208 at the bottom of the piston rod 207 alternately pushes the top of the side walls of the slide detection groove 203, causing the slide detection groove 203 to swing back and forth around the horizontal axis with the bottom center roller 204 as the fulcrum. The self-weight slide in the test mold 205 thus slides back and forth continuously under the action of gravity component, completing the self-weight slide durability test under different environments.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
