[0023] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0024] See also Figure 1-Figure 5 The utility model provides an automatic defrosting device for a quick-freezing warehouse material cart guide rail, which is used for a material cart in a quick-freezing warehouse. The device comprises a guide rail 1, an electric heating tape 2 and a bracket plate 3. The guide rail 1 is used as a support and installation carrier, and is used for the material cart to move along the guide rail. At the same time, it is used to install the electric heating tape 2. The guide rail 1 is in the shape of an "I", and its structure is similar to that of a train guide rail. The bracket plate 3 comprises a plate body 31, and the plate body 31 is fixed to the lower bottom surface of the guide rail 1, and is parallel to and fits the lower bottom surface of the guide rail. In this embodiment, the plate body 31 is fixed to the bottom surface of the guide rail 1 by welding or bolts. The plate body 31 is a strip-shaped plate structure with a thickness of 0.3-1mm and is made of stainless steel. The length direction of the plate body 31 is parallel to the length direction of the guide rail 1. In this embodiment, the plate body 31 is fixed to At the center of the lower bottom surface of the guide rail 1, the edge of the long side (length direction) of the plate body 31 is bent downward to form a first bent portion 32, and the end of the long side (length direction) of the first bent portion 32 is bent outward to form a second bent portion 33. An installation area is formed between the upper bottom surface of the second bent portion 33 and the lower bottom surface of the guide rail 1. The installation area is used to install the electric heating belt 2, that is, the electric heating belt 2 is installed in the installation area. The electric heating belt 2 is flat, and the upper surface of the electric heating belt 2 is attached to the lower bottom surface of the guide rail 1. It can transfer heat to the guide rail 1, thereby realizing defrosting of the guide rail 1. At the same time, the upper surface of the second bent portion 33 is in contact with the electric heating belt 2, thereby realizing compression and support of the electric heating belt 2, so that the electric heating belt can stably and reliably contact the bottom surface of the guide rail 1.

[0025] In the present application, there are two installation areas, which are symmetrically arranged on both sides of the plate body 31, that is, the edges on both sides of the plate body 21 are bent downward to form a first bending portion 32, and the two first bending portions are symmetrically arranged. At the same time, the ends (edges) of the two first bending portions are bent outward to form a second bending portion 33, and the two second bending portions are symmetrical in structure.

[0026] In this embodiment, the edge of the plate body 31 is bent downward to form a first bent portion 32. The angle between the first bent portion 32 and the plate body 31 is greater than or equal to 15 degrees and less than or equal to 45 degrees. At the same time, the end of the second bent portion 33 is bent outward and tilted upward. The angle between the second bent portion and the bottom surface of the guide rail 1 is greater than 0 degree and less than or equal to 5 degrees. The above angle is the angle when the plate body is stamped. The upwardly inclined second bent portion has a certain elasticity, which can produce elastic deformation within a certain angle around the first bent portion. During assembly, the lower bottom surface of the second bent portion is attached to the lower surface of the electric heating belt, which causes the second bent portion to produce elastic deformation. The elastically deformed second bent portion forms an upward pressing force on the electric heating belt, thereby improving the fitting strength between the electric heating belt and the lower bottom surface of the guide rail 1, improving its installation reliability and stability, and avoiding virtual connection between the electric heating belt and the lower bottom surface of the guide rail 1 to affect the heating effect of the guide rail, so as to ensure the reliability and stability of defrosting.

[0027] In this embodiment, the electric heating tape 2 is a flat structure. At the same time, a thermal conductive adhesive is provided between the upper surface of the electric heating tape and the lower surface of the guide rail 1. The thermal conductive adhesive serves to further fix the electric heating tape and at the same time, increase the contact area between the electric heating tape and the bottom surface of the guide rail 1 to ensure full contact between the two and avoid affecting heat transfer due to a gap between the two.

[0028] In order to improve the installation accuracy of the electric heating tape, ensure its linearity, avoid outward deviation, and at the same time, in order to protect the side wall of the electric heating tape, the end of the second bending portion 33 is bent upward to form a limiting portion, which is used to limit the electric heating tape and at the same time, plays a protective role to prevent foreign objects from scratching or crushing the electric heating tape; in this embodiment, the end of the second bending portion 33 is bent upward at an angle to form a first limiting portion 34, and the bending angle of the first limiting portion is 30-60 degrees. The end of the first limiting portion 34 is bent upward to form a second limiting portion 35, and the second limiting portion 35 is perpendicular to the top surface of the second bending portion. After the installation is completed, the second limiting portion is perpendicular to the bottom surface of the guide rail 1, so as to protect the side wall of the electric heating tape. The horizontal projection length of the first limiting portion 34 and the second limiting portion 35 is less than or equal to the thickness of the electric heating tape.

[0029] In the present application, a plurality of dividing grooves 30 are equidistantly arranged on the first bending portion 32 along the length direction of the bracket plate. The dividing grooves 30 are strip-shaped, and their length direction is perpendicular to the length direction of the plate body. The ends of the dividing grooves 30 extend outward to the outside of the bracket plate and divide the second bending portion 33 into a plurality of supporting portions. Each supporting portion can achieve independent support for the electric heating strip. Through this structural setting, the elastic force of the supporting portion can be improved, the clamping support effect and the reliability of the clamping can be improved, and the "line" contact can be converted into "point" contact, with high support reliability and stability.

[0030] Since the bracket plate is in contact with the bottom surface of the electric heating tape, part of the heat will be transferred to the bracket plate. In order to improve the utilization rate of thermal energy and reduce the loss, the plate body 31 is attached to the bottom surface of the guide rail 1, which can transfer the thermal energy on the bracket plate to the guide rail; in order to improve the thermal conductivity efficiency, thermal conductive glue is filled between the plate body 31 and the bottom surface of the guide rail 1, thereby increasing the contact area between the two and improving the thermal energy utilization rate; a thermal insulation layer is provided on the lower surface of the bracket plate 3, and the thermal insulation layer is made of thermal insulation materials, such as glass fiber, asbestos, rock wool, silicate, etc., which can prevent the heat of the bracket plate from being transferred downward and lost, thereby reducing thermal energy loss and having a good energy-saving effect.

[0031] In the present application, the overall width of the bracket plate is smaller than the width of the guide rail 1 , thereby increasing the installation space for fixing the guide rail 1 .

[0032] In order to improve the degree of automation and realize automatic temperature control, in this application, a temperature sensor and a controller are also provided. The temperature sensor is installed on the guide rail to detect the temperature of the guide rail. The temperature sensor and the electric heating belt are respectively connected to the controller for feedback and execution, respectively, to realize automatic heating and defrosting.
