Description

Technical Field

[0001] This utility model belongs to the field of refrigerated truck parts processing technology, specifically relating to a processing device for stainless steel insulation plates for refrigerated trucks. Background Technology

[0002] The core of stainless steel insulation panels for refrigerated trucks is a composite structure of stainless steel panels combined with rigid foam core material. The stainless steel panels need to be degreased and phosphated to remove surface oil and oxide layers, thereby improving the bonding strength with the foam. The core material raw materials (such as isocyanate and polyol of PU) need to be mixed in proportion and the viscosity and reaction temperature controlled.

[0003] Currently, when filling stainless steel sheets with rigid foam, manual operation with a handheld spray gun is often required. This method makes it difficult to control the uniformity of foam spraying, easily leading to overspray or localized air pockets. Furthermore, it is inconvenient to smooth out the sprayed rigid foam, which not only increases subsequent processing steps but also prolongs the processing time. Utility Model Content

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-7 As shown, a stainless steel insulation board processing device for refrigerated trucks includes two support plates 1 and a conveyor belt 2. The conveyor belt 2 is driven by a motor, and the moving speed of the conveyor belt 2 can be controlled according to the spraying requirements. The conveyor belt 2 is connected between the two support plates 1. A stainless steel plate 3 is provided on the upper side of the conveyor belt 2, and a positioning support component is provided on the surface of the conveyor belt 2.

[0027] A baffle assembly is installed on the top surface of the stainless steel plate 3. A bracket 4 is fixedly connected to the side wall of the support plate 1. The bracket 4 is U-shaped. Multiple spray guns 5 are mounted on the top surface of the bracket 4. A feed pipe 6 is fixedly connected to each of the multiple spray guns 5. The spray volume and control method of the spray guns 5 can be achieved by existing technology, which is a mature technology and is not the focus of this solution. Therefore, it will not be described in detail in this solution. A leveling assembly is installed on the side wall of the support plate 1 on the right side of the bracket 4.

[0028] like Figure 1 and Figure 6 As shown, the positioning support assembly includes several rods 7 fixedly connected to the top surface of the conveyor belt 2. The top diameter of the rods 7 is smaller than the bottom diameter. Support plates 8 are inserted into the side walls of the rods 7. Limiting plates 9 are fixedly connected to the top surface of each support plate 8. Stainless steel plate 3 is located between multiple limiting plates 9.

[0029] The top of the insertion rod 7 is threaded. After the stainless steel plate 3 is placed between the limiting plates 9, a nut can be screwed into the top of the insertion rod 7 as needed to increase the stability of the stainless steel plate 3. In addition, every six insertion rods 7 form a group, and the limiting plates 9 distributed at the four corners are L-shaped corner structures, while the limiting plates 9 on the front and rear sides are straight structures, which can position a single stainless steel plate 3.

[0030] like Figure 5 and Figure 7As shown, the enclosure assembly includes a positioning frame 10 disposed on the top surface of the stainless steel plate 3. The bottom of the positioning frame 10 is stepped, and an annular groove 12 is formed on the side wall of the positioning frame 10. Multiple locking components are disposed on the outer side of the positioning frame 10. When the positioning frame 10 is placed on top of the stainless steel plate 3, the stepped structure at the bottom of the positioning frame 10 engages with the side of the stainless steel plate 3. At the same time, the bottom of the positioning frame 10 is flush with the bottom of the stainless steel plate 3 to prevent leakage when spraying liquid rigid foam.

[0031] An annular plastic film 16 is provided on the inner side of the positioning frame 10. The annular plastic film 16 is used to form an easy demolding structure between the expanded rigid foam and the positioning frame 10, so as to facilitate the disassembly of the positioning frame 10. At the same time, it prevents the rigid foam from adhering to the positioning frame 10 and affecting the surface flatness of the positioning frame 10 when it is reused.

[0032] like Figure 3 and Figure 7 As shown, the locking assembly includes a clamping plate 11, which is U-shaped. The two ends of the clamping plate 11 are located on the annular groove 12 and the lower side of the stainless steel plate 3, respectively. A screw 13 is threadedly connected to the bottom surface of the clamping plate 11. A pressure plate 14 is rotatably connected to the top of the screw 13. The pressure plate 14 abuts against the bottom of the stainless steel plate 3 and the positioning frame 10. A rotating wheel 15 is fixedly connected to the bottom of the screw 13.

[0033] The locking assembly allows the positioning frame 10 to be tightly attached to the stainless steel plate 3, which not only provides fixation but also achieves a sealing purpose, thus ensuring good stability during the spraying of liquid rigid foam.

[0034] like Figure 1 and Figure 4 As shown, the leveling assembly includes two electric push rods 17 fixedly connected to the side wall of the support plate 1. The telescopic end of the electric push rod 17 is fixedly connected to a connecting block 18. The side wall of the connecting block 18 is provided with a screw hole, and a bolt 19 is threaded into the screw hole. A connecting post 20 is rotatably connected to the end of the bolt 19. A heating wire 21 is detachably connected between the two connecting posts 20.

[0035] Specifically, the bolts 19 on both sides are used to adjust the tightness of the heating wire 21, and the height of the heating wire 21 can be adjusted by the electric push rod 17 according to the height of the positioning frame 10, so that the heating wire 21 is slightly higher than the top of the positioning frame 10. The excess rigid foam after expansion is cut and leveled, reducing subsequent processing steps. It has the characteristics of simple structure, high automation and strong practicality.

[0036] The connecting post 20 has a through hole on its side wall, and a hook 22 is inserted into the through hole. The two ends of the heating wire 21 are fixedly connected to the hook 22. This facilitates the disassembly of the heating wire 21 for maintenance or replacement in the future.

[0037] The working principle of this utility model is as follows: First, the positioning frame 10 is placed on top of the stainless steel plate 3, and a layer of annular plastic film 16 is wrapped inside the positioning frame 10. Then, one end of the clamping plate 11 is inserted into the annular groove 12, and the other end is placed on the lower side of the stainless steel plate 3. The rotating wheel 15 drives the screw 13 to rotate, and the screw 13 drives the pressure plate 14 to press against the stainless steel plate 3 and the positioning frame 10. Through the fixation of multiple locking components on four sides, the positioning frame 10 is made to be in a stable state. Then, the stainless steel plate 3 is placed on the conveyor belt 2, so that the four corners of the stainless steel plate 3 are located between the limiting plates 9. The running conveyor belt 2 drives the stainless steel plate 3 to move. When the stainless steel plate 3 enters below the spray gun 5, the spray gun 5 begins to spray liquid rigid foam onto the surface of the stainless steel plate 3, causing the liquid rigid foam to expand in the area between the stainless steel plate 3 and the positioning frame 10. After the liquid rigid foam is sprayed, the stainless steel plate 3 is conveyed by the conveyor belt 2 and approaches the heating wire 21. At this time, the heating wire 21 is activated to generate high temperature. At the same time, the conveyor belt 2 begins to convey quickly, so that the excess rigid foam on the positioning frame 10 comes into contact with the heating wire 21 and quickly passes through the heating wire 21, which is used to cut and smooth the excess rigid foam, realizing the integrated spraying and smoothing process and improving processing efficiency.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
