Description

Technical Field

[0001] The utility model relates to the technical field of shoe antifreeze detection, in particular to a shoe antifreeze detection device under deep cold conditions. Background Art

[0002] In order to ensure that shoes can maintain their performance and wearing comfort under low temperature conditions, shoe samples are generally placed in low-temperature testing equipment to test whether the material becomes stiff or brittle by bending, pulling or squeezing.

[0003] The existing patent with publication number CN216847287U discloses a cold-resistant fabric antifreeze detection device, which belongs to the field of fabric antifreeze detection technology, including a device housing, the inner bottom end of the device housing is fixedly connected to an adjustment base, the adjustment base is symmetrically fixedly connected to a fixed column, the inner side of the adjustment base is symmetrically slidably connected to a first sliding block, and the two first sliding blocks are both located between the two fixed columns. One end of the first sliding block extends to the outside of the adjustment base and is provided with a stretching mechanism for pulling the fabric. The two first sliding blocks are driven by a bidirectional screw to move the movable column, and the second sliding block slides in the limiting slide groove to move the roller, which facilitates the pulling detection of fabrics at low temperatures and avoids manual movement of the fabric. The debris in the device housing is recovered by an exhaust fan and transported to the recovery box through a conveying pipe, which facilitates the recovery of the debris and the use of the detection device.

[0004] Although the existing device can detect materials at low temperatures and recycle the generated debris, the exhaust fan will draw away the low-temperature airflow in the equipment during use, resulting in increased energy consumption of the equipment. Based on this, we propose an improved footwear antifreeze detection device under deep cold conditions. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] Combine Figure 1-Figure 7 A shoe antifreeze detection device under deep cold conditions includes a detection device 1, which includes a low-temperature chamber 11 and a loading chamber 12.

[0029] See Figure 1-Figure 5 , it is further obtained that the dust removal mechanism 6 includes an air inlet cover 61 and an exhaust fan 63, the output ends of the air inlet cover 61 and the exhaust fan 63 are both connected to the interior of the low-temperature chamber 11, and an air guide tube 62 is fixedly connected between the air inlet cover 61 and the input end of the exhaust fan 63, one end of the air guide tube 62 is threadedly sleeved with a mounting plug 66, and one end of the mounting plug 66 is fixedly connected to a filter cartridge 65;

A window 4 is fixedly set at the front end of the low-temperature chamber 11, and the window 4 is made of electric heating anti-fog glass.

[0031] Specifically, during dust removal, the exhaust fan 63 draws air so that the air inlet hood 61 can draw the waste into the air guide tube 62, and then enter the filter tube 65 through the guide sleeve 64. The low-temperature airflow then enters the low-temperature chamber 11 again under the guidance of the exhaust fan 63, reducing losses. After the collection is completed, the installation plug 66 is unscrewed to drive the filter tube 65 out of the air guide tube 62. The collected waste is processed, and the situation in the low-temperature chamber 11 can be observed through the anti-fog window 4.

[0032] Example 2

[0033] See Figure 2 、 Figure 3 、 Figure 6 and Figure 7, and on the basis of Example 1, it is further obtained that the detection mechanism 3 includes a slide 31 and a placement platform 33, the slide 31 is arranged at the upper end of the bottom plate of the detection device 1, and an electric push rod 32 is hinged between the upper end of the slide 31 and the placement platform 33, and pressure plates 34 are provided on both sides of the upper end of the placement platform 33. The rear ends of the slide 31 and the pressure plate 34 are respectively fixedly connected to a guide frame 35 and a sliding pin 36, and the sliding pin 36 is slidably sleeved on the guide frame 35;

[0034] A screw rod 2 311 and two slide rods 312 are rotatably and fixedly connected to the inner walls of the side panels of the low-temperature chamber 11 respectively. The slide 31 is threadedly connected to the outer wall of the screw rod 2 311, and the slide 31 is slidably sleeved on the outer wall of the slide rod 312. A motor 2 310 is fixedly arranged on the outer wall of the detection equipment 1. The output end of the motor 2 310 is fixedly connected to one end of the screw rod 2 311.

[0035] Specifically, the electric push rod 32 is used to drive the placement table 33 to descend, and then the two pressure plates 34 can move relative to each other under the guidance of the sliding pin 36 sliding on the guide frame 35 and the sliding block 38 sliding on the surface of the guide rod 37, so as to perform an extrusion test on the shoes. At the same time, the motor 2 310 is used to drive the screw 2 311 to rotate to control the sliding of the slide 31.

[0036] Example 3

[0037] See Figure 2 、 Figure 3 and Figure 7 , and on the basis of Example 1 and Example 2, it is further obtained that the insulation mechanism 2 includes a limit plate 21, an insulation plate 22 and a motor 1 23, the limit plate 21 is slidably sleeved in the insulation plate 22, the motor 1 23 is fixedly connected to the upper end of the top plate of the detection device 1, and a screw rod 1 24 is connected between the motor 1 23 and the insulation plate 22, the insulation plate 22 is threadedly connected to the outer wall of the screw rod 1 24, and the upper end of the screw rod 1 24 is fixedly connected to the output end of the motor 1 23.

[0038] Specifically, when taking and placing shoes, start motor 1 23 to drive screw 1 24 to rotate, and then control the insulation plate 22 to rise vertically relative to the limit plate 21. After the insulation plate 22 rises to the appropriate position, start motor 2 310 to drive screw 2 311 to rotate, and then control the slide 31 to move into the upper material chamber 12. The insulation plate 22 is lowered again to separate the low-temperature chamber 11 and the loading chamber 12, and then open the sealed cabinet door 5 to facilitate taking and placing shoes. Then, test again according to the same principle to avoid taking goods directly from the low-temperature chamber 11, which may cause frostbite on the hands of the staff and cause large-scale leakage of cold air.

[0039] During actual operation, a low-temperature environment is created by the cryogenic chamber 11, and then the electric push rod 32 is actuated to drive the placement table 33 downward, and then the two pressure plates 34 are moved relative to each other by the sliding guide of the guide frame 35 through the sliding pin 36, thereby performing a compression test on the shoes. When waste chips are generated, the exhaust fan 63 is started, and the waste chips are sucked into the air guide tube 62 through the air inlet cover 61, and then enter the filter tube 65 through the guide sleeve 64. The low-temperature air flow is then drawn into the cryogenic chamber 11 again by the exhaust fan 63, thereby reducing losses.

[0040] When it is necessary to replace the shoes for testing, the motor 1 23 is started to drive the screw 1 24 to rotate, thereby controlling the insulation plate 22 to rise vertically relative to the limit plate 21. After the insulation plate 22 rises to a suitable position, the motor 2 310 is started to drive the screw 2 311 to rotate, thereby controlling the slide 31 to move into the upper material chamber 12. The insulation plate 22 is lowered again to separate the low-temperature chamber 11 and the loading chamber 12. Then, the sealed cabinet door 5 is opened to facilitate taking and placing shoes, and then the test is carried out again according to the same principle.

[0041] When the test is completed, the mounting plug 66 can be unscrewed to drive the filter cartridge 65 out of the air guide cylinder 62 and the collected waste can be processed.
