[0023] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0024] See also Figure 1 and Figure 2The foaming device includes: providing a foaming device 100, including a box body 10, a stacking structure 20 and a fixed end plate 30, wherein the box body 10 is provided with a through cavity 101, and the through cavity 101 penetrates the box body 10 along a first direction; the stacking structure 20 is arranged in the through cavity 101, and the stacking structure 20 is provided with a plurality of circular through grooves 211, and the circular through grooves 211 are used to carry the parts to be foamed; the fixed end plate 30 is arranged in the box body 10, and the fixed end plate 30 covers the opening at one end of the through cavity 101, and the through cavity 101 provides space for the stacking structure 20, so that the stacking structure 20 can penetrate the box body 10 along the first direction. The plurality of circular through grooves 211 on the stacking structure 20 are not only used to carry the parts to be foamed, but also ensure that heat can be evenly transferred to each part to be foamed, avoiding heat loss and uneven distribution during the transfer process, thereby ensuring that the parts to be foamed are heated evenly. The fixed end plate 30 is disposed on the box body 10 and covers the opening at one end of the through cavity 101. Such a design not only makes it difficult for the stacked structure 20 to fall in the through cavity 101, but also prevents heat from being lost from one end of the through cavity 101 to a certain extent, ensuring that heat can be effectively circulated and transferred in the through cavity 101, further improving the uniformity of heating.

[0025] It should be noted that the first direction is the penetrating direction of the through cavity 101 , that is, the direction in which the stacked structure 20 is arranged in the box body 10 .

[0026] Please continue reading Figure 2 The stacked structure 20 includes a support plate (not shown) and a plurality of carriers 201. The support plate (not shown) is fixed to the through cavity 101. The plurality of carriers 201 are sequentially arranged side by side on the support plate (not shown). The carrier 201 is provided with the circular through groove 211. By arranging the support plate (not shown), the carrier 201 can be conveniently removed after each foaming is completed. The carrier 201 is not easy to roll. Moreover, the support plate (not shown) enables the entire stacked structure 20 to be firmly placed in the through cavity 101, which ensures to a certain extent that the position of the parts to be foamed remains unchanged during the heating process and is heated evenly. By arranging the carriers 201 side by side, more parts to be foamed can be placed in a limited space, while improving the foaming efficiency to ensure that the heat can be evenly transferred to each part to be foamed.

[0027] In some embodiments, the number of the support plates (not shown) is multiple, and the multiple support plates (not shown) are arranged at intervals along the second direction, so that more carriers 201 and parts to be foamed can be placed in a limited space, thereby improving the space utilization rate of the foaming equipment. A support plate (not shown) carries multiple carriers 201, which are arranged at intervals in the first direction and the second direction, and the second direction is the width direction of the through cavity 101. Heat can be better dispersed and circulated in the through cavity 101, so that each support plate (not shown) and the carrier 201 thereon can be evenly heated. This helps to avoid the situation where the parts to be foamed are locally overheated or underheated, and improves the uniformity of the foaming effect.

[0028] In an embodiment of the present application, the supporting member 201 is a circular tube kit, and the supporting plate (not shown) is provided with a plurality of arc-shaped supporting grooves, one of the arc-shaped supporting grooves being used to support the supporting member 201, and the arc-shaped supporting groove can prevent the supporting member 201 from rolling on the supporting plate (not shown), and the position of the supporting member 201 remains unchanged. The design of the arc-shaped supporting groove makes the installation and disassembly of the circular tube kit simple and convenient, and the operator can easily put the supporting member 201 into or take it out of the arc-shaped supporting groove, thereby improving work efficiency.

[0029] Please refer to Figure 2 The fixed end plate 30 is provided with a plurality of ventilation holes 301, which ensure that heat can be directly and efficiently transferred to each carrier 201, reducing the loss of heat during the transfer process, not only improving the thermal efficiency, but also shortening the time required for the foaming of the foamed part. The ventilation holes 301 are used for gas to pass through the circular through groove 211, and the fixed end plate 30 is also provided with a plurality of card slots (not shown in the figure), which are arranged between adjacent ventilation holes 301. A protrusion (not shown in the figure) is provided at one end of the carrier 201, and the protrusion (not shown in the figure) is used for detachable card connection with the card slot (not shown in the figure). Through the above design, the detachable card connection between the carrier 201 and the fixed end plate 30 is realized, which not only facilitates the installation and disassembly of the carrier 201, but also improves the stability and reliability of the stacked structure 20. The cooperation between the card slot (not shown) and the protrusion (not shown) can ensure that the part to be foamed remains in a fixed position during the heating and foaming process to prevent it from moving or deforming.

[0030] In the embodiment of the present application, the diameter of the ventilation hole 301 is smaller than the inner diameter of the supporting member 201 , so as to prevent the supporting member 201 from slipping through the ventilation hole 301 .

[0031] See also Figure 3The box body 10 includes a first end plate 102, a second end plate 103, a third end plate 105 and a bottom plate 104, the first end plate 102, the second end plate 103, the third end plate 105 and the bottom plate 104 are connected end to end in sequence, the first end plate 102, the second end plate 103, the fixed end plate 30, the third end plate 105 and the bottom plate 104 enclose the through cavity 101, the fixed end plate 30 is arranged at one end of the first end plate 102, the second end plate 103, the third end plate 105 and the bottom plate 104 along the first direction, and the surface of the third end plate 105 away from the through cavity 101 is provided with a handle 106, so that the operator can easily move the entire box body 10 through the handle 106, which is convenient for movement and transfer between different work locations. At the same time, the setting of the handle 106 will not cause any interference to the foaming process in the through cavity 101, ensuring the normal operation of the foaming equipment.

[0032] The embodiment of the present application provides a foaming device, including a box body 10, a stacking structure 20 and a fixed end, the loading box body 10 is provided with a through cavity 101, and the through cavity 101 penetrates the loading box body 10 along a first direction; the stacking structure 20 is arranged in the through cavity 101, and the stacking structure 20 is provided with a plurality of circular through grooves 211, and the circular through grooves 211 are used to carry the parts to be foamed; the fixed end plate 30 is arranged in the loading box body 10, and the fixed end plate 30 covers the opening at one end of the through cavity 101.
