Description

Technical Field

[0001] This utility model belongs to the field of refrigerator parts processing technology. Specifically, this utility model relates to a structure for detecting the height of heated ABS sheet material in a refrigerator. Background Technology

[0002] ABS sheet is a common type of plastic sheet, which is polymerized from three monomers: acrylonitrile, butadiene, and styrene. It has the advantages of readily available raw materials, low price, and good overall performance. ABS sheet can be used as refrigerator liner or door sheet.

[0003] In the production of ABS sheets for refrigerators, heating is required to soften the ABS sheets, increasing their plasticity to facilitate subsequent molding, bending, and folding operations. During the heating process, the heating temperature has a significant impact on the processing quality of the ABS sheets. However, in existing heating equipment, the heating components cannot accurately reflect the degree of softening of the ABS sheets, making it difficult to control the temperature parameters properly and affecting the processing quality.

[0004] For example, invention patent CN109054279A, published on December 12, 2018, discloses an ABS sheet, a refrigerator liner, and a method for preparing the ABS sheet. However, this method for preparing the ABS sheet, refrigerator liner, and ABS sheet does not solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a structure for detecting the hanging height of ABS sheets in refrigerators, which helps ensure the processing quality of ABS sheets.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The refrigerator ABS board heating and hanging height detection structure includes a frame and a heating component. The frame is equipped with a material support plate, and the two ends of the ABS board are placed on the material support plate. A measuring unit is located above the middle of the ABS board.

[0007] The measuring unit includes a laser rangefinder sensor, and a connecting rod is detachably connected to the top of the frame, with the laser rangefinder sensor located in the middle of the connecting rod.

[0008] The top of the frame is also fixedly connected to a connecting plate. There are two connecting plates, and the two ends of the connecting rod are respectively bolted to the two connecting plates. The connecting plate is provided with a first waist-shaped hole, and the connecting rod is provided with a second waist-shaped hole in the middle. The cross-section of the connecting plate and the cross-section of the connecting rod are both L-shaped structures.

[0009] The material support plate is connected to a lifting assembly, and a pressure plate is provided above the material support plate inside the frame. The material support plate and the pressure plate press against the two sides of the ABS plate.

[0010] The heating assembly is provided in two parts, with the two heating assembly plates respectively located on the upper and lower sides of the ABS plate.

[0011] The top surface of the material support plate and the bottom surface of the pressure plate are both provided with pressure teeth.

[0012] The frame is constructed by welding square tubes.

[0013] The technical advantages of this invention are as follows: The refrigerator ABS sheet heating and drooping height detection structure of this invention softens the ABS sheet while measuring the drooping height of the ABS sheet after heating using a laser rangefinder sensor. This allows for control of the heating components to adjust temperature parameters and ensure the subsequent processing quality of the ABS sheet. The laser rangefinder sensor is modularly installed, which has the advantages of small size and small space occupation. It is easy to install directly on existing heating equipment, has little impact on existing components of existing equipment, and reduces development and modification costs.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0017] The refrigerator ABS board heating and hanging height detection structure includes a frame 2 and a heating component 3. The frame 2 is equipped with a material support plate 4. The two ends of the ABS board 1 are placed on the material support plate 4. A measuring unit is provided above the middle of the ABS board 1.

[0018] like Figure 1 and Figure 2 As shown, Figure 1 for Figure 2 The upper half of the components and the structural view of the hidden frame 2; the frame 2 is used to provide installation positions for each component, the heating component 3 is the prior art, which is composed of heating wires made of multiple sets of heat-conducting mesh layers, used to achieve uniform heating, the material support plate 4 is used to support the edge of ABS, so that the middle of the ABS plate 1 is unsupported, so that it naturally sinks after being heated and softened to form a drooping material, so as to facilitate the detection of the measuring unit.

[0019] The principle of detecting the sag height is as follows: After the horizontally placed ABS sheet 1 is heated and softened, the unsupported area of ​​the ABS sheet 1 will produce a concave deformation to form a sag. The distance measurement of the sag height of the ABS sheet 1 is detected by the measuring unit. The change in the value of this distance directly reflects the degree of softening of the ABS sheet 1, thereby making the temperature parameters more reasonable and avoiding the problems of insufficient or excessive softening, so as to ensure the processing quality of the ABS sheet 1.

[0020] like Figure 2 As shown, the measuring unit includes a laser rangefinder sensor 5, and a connecting rod 6 is detachably connected to the top of the frame 2. The laser rangefinder sensor 5 is located in the middle of the connecting rod 6. The laser rangefinder sensor 5 can measure the height of the ABS sheet after heating and feed the measurement data back to the equipment control system, thereby controlling the heating component 3 to adjust the temperature parameters and ensure the processing quality of the ABS sheet 1. The laser rangefinder sensor 5 is modularly installed through the connecting plate 7 and the connecting rod 6. This modular structure is small in size and occupies little space. It will not interfere with the position or function of existing components and can be directly installed on top of existing heating equipment without extensive disassembly or adjustment of existing components, thus reducing development costs.

[0021] like Figures 1 to 4As shown, a connecting plate 7 is fixedly connected to the top of the frame 2. Two connecting plates 7 are provided, and the two ends of the connecting rod 6 are bolted to the two connecting plates 7 respectively. The connecting plate 7 has a first oblong hole 8, and the connecting rod 6 has a second oblong hole 9 in the middle. Both the connecting plate 7 and the connecting rod 6 have L-shaped cross-sections. In this structure, the connecting plate 7 is welded to the frame 2 to connect and support the connecting rod 6. The end of the connecting rod 6 is fixed to the connecting plate 7 with bolts. The lateral installation position of the connecting rod 6 can be adjusted through the first oblong hole 8. Simultaneously, the laser rangefinder 5 is bolted to the second oblong hole 9 on the connecting rod 6, allowing for longitudinal adjustment of its installation position. The two oblong holes enable planar position adjustment of the laser rangefinder 5, ensuring that the vertical downward direction of the laser rangefinder 5's detection end is unobstructed, accurately aligning with the center position of the ABS sheet heating, thereby ensuring the accuracy of the ABS sheet 1's vertical height detection. Angle steel can be used for both the connecting rod 6 and the connecting plate 7 to reduce installation difficulty and manufacturing costs.

[0022] like Figure 2 As shown, the support plate 4 is connected to a lifting assembly 12. A pressure plate 10 is located above the support plate 4 within the frame 2. The support plate 4 and the pressure plate 10 press against the two sides of the ABS sheet 1. The lifting assembly 12 includes a cylinder mounted on the support plate 4 and a gear and rack transmission mechanism that provides guidance. This is existing conventional technology and can also be replaced by other linear drive mechanisms. After the cylinder is driven by the lifting assembly 12, the two sides of the ABS sheet 1 are pressed against the support plate 4 and the pressure plate 10, improving the stability of the ABS sheet 1. Simultaneously, the height of the ABS sheet 1 is increased, ensuring that the concave center after heating and softening does not contact the heating assembly 3 or other components.

[0023] like Figure 1 As shown, there are two heating components 3, with the two heating component 3 plates respectively located on the upper and lower sides of the ABS plate 1. This structure, with two sets of heating units, heats both the upper and lower sides of the ABS plate 1, which not only improves heating efficiency but also enhances the uniformity of heating the ABS plate.

[0024] like Figure 5 As shown, pressure teeth 11 are provided on the top surface of the support plate 4 and the bottom surface of the pressure plate 10. The pressure teeth 11 improve the roughness of the top surface of the support plate 4 and the bottom surface of the pressure plate 10, thereby improving the stability of the ABS plate 1 when it is placed on the support plate 4 and when it is pressed by the support plate 4 and the pressure plate 10.

[0025] like Figure 2 As shown, frame 2 is constructed by welding square tubes. In this structure, the square tube serves as the main structure of frame 2, resulting in a simple structure, low cost, and ease of welding connecting plates 7 and connecting rods 6 for installing the laser rangefinder sensor 5. It also facilitates the installation of the laser rangefinder sensor 5 on existing heating equipment, reducing the high cost of retrofitting existing equipment.

[0026] The detection process of the laser rangefinder sensor 5 is as follows: Driven by the cylinder lifting assembly, the material support plate 4 rises and presses the two sides of the ABS plate 1 against the pressure plate 10. At the same time, the upper and lower heating units start to heat the ABS plate 1. After the ABS plate is heated, its middle part is concave and deformed. The laser rangefinder sensor 5 starts and measures the distance between itself and the center of the concave part of the ABS plate 1 to detect the vertical height of the ABS plate 1. This distance data is fed back to the control system to adjust the heating temperature and ensure that the temperature parameters are qualified.

[0027] The refrigerator ABS board heating and sagging height detection structure softens the ABS board 1 while measuring the sagging height of the ABS board after heating using a laser rangefinder 5. This allows for control of the heating component 3 to adjust temperature parameters and ensure the subsequent processing quality of the ABS board 1. The laser rangefinder 5 is modularly installed, which has the advantages of small size and small space occupation. It is easy to install directly on existing heating equipment, has little impact on existing components of the existing equipment, and reduces development and modification costs.

[0028] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
