Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, a preheating device is used to preheat the thermal insulation component 6 to improve the detection efficiency of the thermal insulation component 6.

[0024] The preheating device includes a pressing plate assembly 2, a heating block 3, and a pressing block 4. The heating block 3 is installed on the upper end of the base 1. The main body of the heating block 3 is a rectangular parallelepiped structure. The heating block 3 includes a heating surface 31. The heating surface 31 is the bottom surface of a semi-cylindrical trough structure formed by being recessed downward along the top of the heating block 3. The heating surface 31 is in an arc shape. The distance between the left and right sides of the upper end of the heating surface 31 is less than the maximum distance between the left and right sides of the upper end surface of the heating block 3. A heat insulating component 6 is placed on the upper end surface of the heating block 3. The heat insulating component 6 is made of aerogel and is a rectangular parallelepiped plate structure. The heat insulating component 6 is sealed above the heating surface 31.

[0025] like Figure 1 As shown, the pressing block 4 is located above the heating surface 31, the pressing block 4 is a cylindrical structure, the outer wall of the pressing block 4 is also arc-shaped, and the arc radius of the outer wall of the pressing block 4 is smaller than the arc radius of the heating surface 31. The upper end of the pressing block 4 is fixedly connected with a driving component 5, the driving component 5 is a cylinder, and the driving component 5 can drive the pressing block 4 to move up and down, so that the pressing block 4 can be inserted into the heating block 3, so that the pressing block 4 can be close to the heating surface 31.

[0026] like Figure 1 As shown, the bottom of the pressing block 4 abuts against the upper end of the heat insulating component 6. When the pressing block 4 is inserted downward into the heating block 3, the pressing block 4 presses the heat insulating component 6 into the heating block 3, so that the heat insulating component 6 forms a Figure 4In the semicircular structure shown, the lower wall of the heat insulating component 6 fits with the heating surface 31. By heating the heating block 3, the heating surface 31 transfers heat to the heat insulating component 6, so that the wall of the heat insulating component 6 and the heating surface 31 fit together are heated and heated. Since the material of the heat insulating component 6 is relatively soft, after the heat insulating component 6 forms a curved semicircular structure, the lower wall of the heat insulating component 6 forms a curved and open shape, and its surface area is expanded. In addition, the upper part of the heat insulating component 6 is pressed down by the pressing block 4, so that the fit between the lower wall of the heat insulating component 6 and the heating surface 31 is increased, which is also conducive to accelerating heat transfer and improving the heating efficiency.

[0027] like Figure 1 As shown, the pressing plate assembly 2 is located on both sides of the heating surface 31 in the radial direction. Figure 2 As shown, the pressure plate assembly 2 includes a fixed block 21, a pressure plate body 22, and a spring 23. The fixed block 21 is provided with a first slot 211, and the pressure plate body 22 is inserted into the first slot 211 and can slide along the inner wall of the first slot 211, as shown in FIG. Figure 1 , Figure 4 As shown, the pressing plate body 22 can move closer to or farther from the heating surface 31 along the radial direction of the heating surface 31 when sliding. Figure 1 The middle pressure plate body 22 slides left and right).

[0028] like Figure 2 As shown, the lower end of the pressing plate body 22 can extend out of the fixing block 21, and the pressing plate body 22 is provided with an extension plate 221. Figure 1 The extension plate 221 is located on the side of the platen body 22 away from the heating surface 31 (i.e. Figure 2 The middle pressure plate body 22 is located above the middle pressure plate body 22).

[0029] like Figure 2 As shown, the extension plate 221 is provided with a second slot 2211. Figure 3 As shown, the second slot body 2211 passes through the extension plate 221 from top to bottom.

[0030] like Figure 1 , Figure 3 As shown, the pressing plate body 22 also includes a third slot body 222 located on a side close to the heating block 3. The third slot body 222 forms a notch at the lower right corner of the pressing plate body 22. The third slot body 222 includes Figure 3 The second wall 2222 on the left and the first wall 2221 on the top are combined Figure 1 The left and right sides of the heat insulation component 6 are respectively inserted into the corresponding third groove bodies 222, and the first wall surface 2221 and the second wall surface 2222 form limit positions on the left and right sides and the top of the heat insulation component 6.

[0031] like Figure 2As shown, the fixing block 21 is also provided with an extension groove 212, which is located on both sides of the length direction of the first groove body 211, and the extension groove 212 is recessed and extends away from the pressure plate body 22. The extension groove 212 is connected to the first groove body 211, and the spring 23 is located in the extension groove 212, one end of the spring 23 abuts against the pressure plate body 22, and the other end of the spring 23 abuts against the inner wall of the extension groove 212.

[0032] like Figure 3 As shown, the pressure plate assembly 2 is installed with an adjustment assembly 7, which includes an insertion rod 71 and an adjustment block 72 located below the insertion rod 71. The insertion rod 71 is inserted into the fixed block 21, and the upper end of the insertion rod 71 extends out of the fixed block 21. A handle is provided at the upper end of the insertion rod 71, and the insertion rod 71 can be rotated by the handle. A groove is provided on the outer wall of the bottom of the insertion rod 71, and a corresponding protrusion is provided on the inner wall of the adjustment block 72. The protrusion of the adjustment block 72 is inserted into the groove of the insertion rod 71, and when the insertion rod 71 rotates, it can drive the adjustment block 72 to rotate synchronously.

[0033] like Figure 2 As shown, the adjustment block 72 is a cam, and its cross-section is elliptical. The adjustment block 72 is located in the second slot 2211. Figure 2 In the state shown, the upper and lower ends of the outer wall of the adjustment block 72 abut against the upper and lower walls of the second slot 2211. At this time, the spring 23 is in a compressed state. In this state, Figure 1 As shown, the heat insulation component 6 is inserted into the third slot 222, and the middle upper end of the heat insulation component 6 abuts against the pressing block 4. Then rotate the insertion rod 71 to rotate the adjustment block 72 to Figure 5 , Figure 6 The state shown, combined Figure 1 Since the two sides of the heat insulation component 6 are against the pressing plate body 22, the pressing plate body 22 remains in place. Figure 4 As shown, when the pressing block 4 presses down the heat insulating component 6, during the process of gradually pressing the heat insulating component 6 into the heating block 3, under the action of the spring 23, the pressing plate bodies 22 on both sides press against the two sides of the heat insulating component 6 until the heat insulating component 6 completely enters the heating block 3. During the process of the pressing plate body 22 moving toward the pressing block 4, the pressing plate body 22 can be inserted into the fourth groove 41, so that after the heat insulating component 6 is pressed into the heating block 3, the bottom of the pressing plate body 22 can press the upper parts of both ends of the heat insulating component 6 to prevent the heat insulating component 6 from slipping.

[0034] By providing the pressing plate bodies 22 on both sides, the heat insulating component 6 will not slide left and right when being pressed into the heating block 3 , thereby preventing a portion of the heat insulating component 6 from being able to fit in with the heating surface 31 for heating.

[0035] When the adjusting block 72 is rotated to Figure 2 During the process of the position shown in the figure, the adjusting block 72 abuts against the inner wall of the second groove body 2211 and drives the pressing plate body 22 to move upward, that is, Figure 1The left-side pressing plate body 22 moves to the left, and the right-side pressing plate body 22 moves to the right, so as to facilitate the placement of the next heat insulation component 6.
