Description

Technical Field

[0001] This utility model relates to the field of ceramic tile baking equipment technology, and in particular to an infrared lampshade for ceramic tile baking equipment. Background Technology

[0002] In scenarios such as tile replacement and renovation, it is necessary to use baking equipment to heat the structural adhesive on the back of the tile to soften it, so that the tile can be removed completely. Currently, the mainstream heating devices on the market are heating wires or heating tubes, but these devices have significant drawbacks: they use indirect heat transfer, resulting in dispersed heat, low heating efficiency (heat utilization rate less than 60%), and poor temperature controllability, making it impossible to accurately match the softening temperature range of the structural adhesive, which can easily lead to problems such as tile cracking and glaze peeling; at the same time, traditional heating wire / heating tube devices are not equipped with effective temperature measurement structures, and temperature monitoring relies on manual experience, making it difficult to ensure the consistency of the structural adhesive softening effect.

[0003] With technological advancements, infrared baking has gradually become the preferred solution for tile baking due to its advantages of direct radiative heat transfer and precise heating. However, the corresponding infrared lamp cover, as a core component, still faces the following key issues: Currently, infrared lamps in baking equipment are mostly secured with screws, which can easily scratch the lamp surface or damage the installation structure during disassembly. Existing lamp covers are mostly closed or semi-closed structures, and the temperature measurement module often cannot directly detect the temperature of the structural adhesive on the back of the tile due to the obstruction of the lamp cover shell. It can only indirectly measure the ambient temperature of the lamp cover or the heating area, resulting in large temperature monitoring errors, usually exceeding ±10℃. At the same time, the lamp installation position can easily block the temperature measurement path, further aggravating temperature measurement interference. This can easily lead to problems such as overheating of the structural adhesive, causing tile breakage, or insufficient heating, resulting in incomplete softening.

[0004] For example, the patent document with patent number CN201920140826.6 and patent name "A Tile Replacement Device" discloses a tile replacement device, which includes a baking component that can melt and disable the structural adhesive behind the tile when it is close to the wall. The tile replacement device also includes an adsorption component that can contact the tile and remove the tile after the baking component melts and disables the structural adhesive behind the tile.

[0005] The baking assembly in the aforementioned patent document uses heating wires / heating tubes, which are prone to causing tile cracking and glaze peeling. Furthermore, it lacks a temperature measuring device, making temperature monitoring difficult.

[0006] This utility model aims to address the shortcomings of the existing technology by providing an infrared lamp cover for a ceramic tile baking device. The lamp tube can be quickly installed and removed by the bracket, and the heating efficiency and temperature controllability are improved by direct radiative heat transfer. Utility Model Content

[0007] Therefore, it is necessary to provide an infrared lampshade for a tile baking device to address the problems of existing technologies, in order to replace the existing heating devices that use heating wires / heating tubes and cannot be quickly disassembled.

[0008] To solve the problems of the existing technology, the present invention adopts the following technical solution: An infrared lampshade for a ceramic tile baking device includes a housing, a support, and a lamp tube. The housing consists of a base and a raised platform, and the raised platform has an internal receiving chamber. The support and the lamp tube are both disposed in the receiving chamber. The bottom of the support is a rectangular base, with two symmetrical clamping arms extending upward. The upper part of the clamping arms bends towards the opposite position to form clamping openings. The lamp tube is provided with the support at both ends, clamping it in the clamping openings.

[0009] Furthermore: the base is a flat base, the raised platform is a rectangular platform, the area of ​​the rectangular platform is smaller than that of the base, and the sides of the raised platform are trapezoidal.

[0010] Furthermore, a waist-shaped hole is provided on one side of the raised platform, and lampshade mounting holes are symmetrically provided on both sides of the top plane of the raised platform, which are fastened to the lampshade mounting position by bolts.

[0011] Furthermore: a temperature measuring hole is provided at the center of the top of the raised platform, and the temperature measuring hole is a circular through hole; an even number of bracket mounting positions are symmetrically provided between the temperature measuring hole and the lamp cover mounting hole to ensure that the lamp tube does not block the temperature measuring hole in the vertical direction.

[0012] Furthermore: the bracket is integrally formed from an elastically deformable alloy, and the rectangular base at the bottom of the bracket is a rectangular flat plate with bracket mounting holes, which are fastened to the bracket mounting position by bolts.

[0013] Furthermore: the clamping arm is S-shaped, and the lower part of the clamping arm is provided with an inwardly oriented base support arm at the connection part with the rectangular base. The upper part of the base support arm is connected to an arc arm, and the arc arm is bent in the opposite direction to form a clamping opening. The curvature of the clamping opening is adapted to the shape of the lamp tube and can form a close contact with the surface of the lamp tube, thereby improving the clamping stability.

[0014] Furthermore, the clamping arm has a pinching part at its top, which is a widened structure extending outward from the top of the clamping arm with rounded edges.

[0015] The beneficial effects of this utility model are as follows: This invention utilizes a one-piece molded bracket design made of elastic alloy, combined with a widened gripping part at the top of the clamping arm, allowing for quick and easy manual opening of the clamping arm without tools, facilitating convenient insertion and removal of the lamp tube. Simultaneously, the curvature of the clamping opening precisely matches the shape of the lamp tube, ensuring a secure and stable installation, preventing loosening or scratches during use, and extending the lamp tube's lifespan. A circular temperature measuring hole at the center of the raised platform provides an unobstructed detection channel for the temperature measuring module. The bracket mounting positions are symmetrically distributed and avoid the temperature measuring hole, ensuring the lamp tube does not obstruct the temperature measurement path, reducing infrared radiation interference, and controlling the temperature measurement error within ±2℃, far superior to the ±10℃ or higher error range of traditional lampshades. Precise temperature detection provides real-time feedback on the temperature status of the structural adhesive on the back of the tile, and, in conjunction with a temperature alarm, can promptly avoid overheating risks, improving the tile's integrity rate.

Detailed Implementation

[0017] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0018] Please see Figures 1 to 4 As shown, this utility model discloses an infrared lampshade for a ceramic tile baking device, which consists of a shell 1, a bracket 2, and a lamp tube 3.

[0019] The outer shell 1 is an integrally formed alloy structure, consisting of a base and a raised platform. The base is a rectangular flat plate structure that can fit tightly against the surface of the ceramic tile to be baked. The raised platform is a trapezoidal three-dimensional structure with a rectangular platform at the top. The area of ​​the rectangular platform is smaller than that of the base, forming a trapezoidal structure on the sides. Furthermore, in order to accommodate the bracket 2 and the lamp tube 3, the raised platform is a hollow accommodating chamber.

[0020] Furthermore, in order to run the power cord of the lamp tube 3 and at the same time serve as a heat dissipation channel to reduce the temperature of the accommodating chamber by 6-9°C, a waist-shaped hole 101 is provided on one side of the raised platform.

[0021] Furthermore, in order to facilitate the installation of the lampshade on the lampshade mounting position of the baking equipment, two lampshade mounting holes 102 are symmetrically distributed on the left and right sides of the top plane of the raised platform. The lampshade mounting holes 102 are countersunk holes and are fastened to the mounting position with bolts.

[0022] Since the temperature of the structural adhesive on the back of the tile needs to be detected in the tile baking process, rather than other ambient temperatures, a temperature measuring hole 103 is provided at the geometric center of the top plane of the raised platform. The temperature measuring hole 103 is a circular through hole. If the temperature measuring hole 103 is not provided, the infrared thermometer can only detect the temperature of the lamp cover shell 1, or the infrared signal will be weak and the temperature measurement error will be large due to the obstruction of the shell 1, making it impossible to accurately determine whether the structural adhesive has softened or whether the tile is close to the upper limit of its tolerance temperature.

[0023] Furthermore, in order to install the lamp tube 3, four bracket mounting positions 104 are provided on the top plane of the raised platform. The bracket mounting positions 104 are divided into two groups and symmetrically distributed between the temperature measuring hole 103 and the lamp cover mounting hole 102. The length of the line connecting the centers of the holes is adapted to the length of the lamp tube 3.

[0024] Furthermore, in order to prevent the infrared radiation of the lamp tube 3 from interfering with the infrared temperature measurement, the layout design of the mounting position of the bracket 2 ensures that the lamp tube 3 does not block the temperature measurement hole 103 after the bracket 2 is installed.

[0025] Furthermore, in order to fix the infrared lamp tube 3, the bracket 2 is made of spring steel in one piece by stamping, with a thickness of 1mm. After heat treatment, the elastic recovery rate is ≥96%, and it can withstand more than 1200 opening and closing operations without failure, thus avoiding the problem of loosening or deformation of the bracket 2.

[0026] Furthermore, in order to lock the bracket 2, each bracket has a rectangular base 200 at the bottom with a bracket mounting hole 201. The edges of the through hole are rounded, and the bracket 2 can be firmly fastened to the mounting position of the bracket 2 with bolts. After installation, the fit gap between the bracket 2 and the platform is ≤0.3mm.

[0027] The bracket 2 extends two symmetrical clamping arms 202 upward from both ends of the base. The clamping arms 202 are S-shaped. The lower part of the clamping arms is provided with an inward base support arm 204 at the connection part with the rectangular base 200. The base support arm 204 extends upward from the rectangular base to form a trapezoidal flared shape, which is intended to enhance the dispersion of structural forces and avoid stress concentration.

[0028] Two symmetrical arc arms 205 extend upwards from the base support arm 204, with smooth, curved bodies providing ample allowance for elastic deformation. These arc arms bend in opposite directions to form clamping openings 206, with an arc of 130°, perfectly matching the shape of the lamp tube 3. This allows for close contact with the surface of the lamp tube 3, and, combined with elastic restoring force, clamps the lamp tube securely, preventing loosening or scratches. This is the core structure for achieving stable lamp tube installation.

[0029] Furthermore, in order to improve the ease of installation and removal of the lamp tube 3, a pinching part 203 is provided at the top of the clamping arm. Since the clamping arm of the bracket 2 is thin and requires elastic deformation to open, if the clamping arm is pried open directly, not only is a large force required, but it is also easy to slip due to the instability of the force application point. The widened pinching part 203 reduces the operating force by extending the lever arm, allowing the operator to pry open the clamping arm accurately and effortlessly, thus realizing the quick installation and removal of the lamp tube 3.

[0030] Preferably, the lamp tube 3 is made of two medium-wave infrared heating lamp tubes 3, which are adapted to the softening requirements of structural adhesive at 120-190℃, and the surface of the lamp tube 3 is high-transparency quartz glass.

[0031] Furthermore, to prevent damage to the tiles / structural adhesive due to overheating and to prevent safety hazards caused by overheating of the equipment, the alarm temperature of the infrared thermometer is set at 200℃. The temperature probe is inserted through the temperature measuring hole 103 to directly detect the temperature of the tiles. When the temperature exceeds 200℃, an alarm is triggered, and the operator immediately presses the emergency stop button or turns off the heating switch, cuts off the power to the lamps, and prohibits further heating; thus providing a safety guarantee for the tile baking process.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
