Technical Field

[0001] This utility model belongs to the field of ETFE membrane coating technology, and in particular relates to a quick-change ETFE membrane coating device. Background Technology

[0002] ETFE (ethylene-tetrafluoroethylene copolymer) membrane materials are widely used in the construction industry, especially for the exterior walls or roofs of large public facilities, due to their excellent weather resistance, light transmittance, and good chemical stability. However, there are certain technical challenges in the construction process of ETFE membranes, particularly in the process of applying adhesives to the membrane surface.

[0003] Most adhesive scraping tools only consider a specific adhesive scraping need, such as spreading the adhesive evenly or reducing the amount of adhesive, making it difficult to meet the diverse operational requirements of the construction site. For working environments with different heights or angles, traditional tools lack effective adjustment mechanisms, resulting in low operating efficiency and easy instability in construction quality. When different adhesive scraping components need to be replaced according to different work needs, traditional tools usually require a complicated disassembly and installation process, which is time-consuming and increases labor costs.

[0004] To address these issues, we provide a quick-change ETFE membrane coating device. Utility Model Content

[0024] Example

[0025] Please see Figure 1-4 This utility model relates to a quick-change ETFE membrane scraping device, comprising a support assembly 100 and a scraping assembly 200 installed at the end of the support assembly 100; the support assembly 100 includes a base 101, a positioning ball shell 102 that mates with the ball head structure at the top of the base 101, a support column 103 fixed to the top of the positioning ball shell 102, a sleeve 104 fixed to the upper end of the support column 103, a telescopic rod 106 telescopically fitted inside the sleeve 104, and a connector 107 threadedly fitted to the front end of the telescopic rod 106; the scraping assembly 200 includes a bracket 201 fixed to the connector 107, an arc-shaped scraper 202 embedded in one side of the bracket 201, and an embedded... The triangular scraper 203 on the other side of the bracket 201, and the baffles 204 installed at both ends of the bracket 201 via fastening knobs 205; the installation and fixation of the scraper assembly 200 is achieved by setting a rotatable and telescopic adjustable support component 100, which facilitates the position adjustment of the scraper assembly 200. At the same time, the support component 100 has a simple structure and is easy to install and remove, which facilitates the quick replacement of the scraper assembly 200. The scraper assembly 200 is equipped with two types of scraping structures: an arc-shaped scraper 202 and a triangular scraper 203, which can be selected according to actual usage requirements. The triangular scraper 203 is used to reduce the amount of glue, while the arc-shaped scraper 202 is used more for spreading the amount of glue. Switching between the two expands the applicability of the device.

[0026] Specifically, the base 101 has elastic buttons 101a symmetrically arranged on the periphery of the ball head structure at the top. The elastic buttons 101a are adapted to the positioning holes 102a provided at the edge of the opening of the positioning ball shell 102. After the elastic buttons 101a are pressed and retracted, the positioning ball shell 102 loses its external constraint and can be rotated for adjustment. To ensure that the elastic buttons 101a can cooperate normally with the positioning holes 102a, the positioning ball shell 102 is kept to rotate around its own axis. The telescopic rod 106 has limiting holes 106a equidistantly provided along its length for the installation of the pins 105. The telescopic rod 106 is fixed to the sleeve 104 by the pins 105, realizing the rapid positioning of the telescopic rod 106 during the telescopic adjustment process.

[0027] The bracket 201 has grooves on both sides for mounting the arc-shaped scraper 202 and the triangular scraper 203, and screw holes at both ends for mounting the fastening knob 205. The baffle 204 covers the ends of the grooves on both sides of the bracket 201, and the inner side of the baffle 204 is in contact with the ends of the arc-shaped scraper 202 and the triangular scraper 203 to prevent the arc-shaped scraper 202 and the triangular scraper 203 from detaching from the bracket 201 during the glue scraping stage.

[0028] Furthermore, the lower edge of the base 101 is integrally provided with an annular mounting edge, and the annular mounting edge is provided with mounting holes for fastener installation at equal intervals. The annular mounting edge is fixed to the outer support surface by fasteners. After the position of the base 101 is fixed, the overall position of the device is fixed. The inside of the support column 103 is hollow, and its cavity is also used to accommodate the telescopic rod 106. Reinforcing ribs are provided continuously at equal intervals on the periphery of the support column 103 to improve the structural strength of the support column 103.

[0029] The operation process in this embodiment is as follows:

[0030] Install the device at the location of the ETFE film to be treated, and use the selected scraper (arc scraper 202 for evenly spreading the adhesive, triangular scraper 203 for reducing the adhesive) to scrape the adhesive. According to the actual needs, rotate the positioning ball shell 102 to adjust the angle of the support component 100. During the adjustment process, press the elastic button 101a to retract it so that the positioning ball shell 102 can rotate freely. After adjusting to the required angle, release the elastic button 101a to re-engage with the positioning hole 102a and lock the position. Then, according to the operating height requirements, adjust the length of the telescopic rod 106 in the sleeve 104. Insert the pin 105 by selecting the appropriate limiting hole 106a to fix the position of the telescopic rod 106 and achieve quick positioning.

[0031] When it is necessary to replace the arc-shaped scraper 202 or the triangular scraper 203, loosen the fastening knob 205, remove the baffle 204, and pull out the corresponding scraper structure from the groove of the bracket 201 for replacement.
