Description

Technical Field

[0001] This utility model relates to the field of bamboo board production and processing technology, and in particular to a multi-layer bamboo board glue scraping device. Background Technology

[0002] Bamboo plywood is made from finely processed bamboo strips that are glued and pressed together to form boards and square timber. Bamboo plywood production typically requires 4-6 year old, large-diameter moso bamboo, which undergoes dozens of processes including sawing, slicing, rough planing, high-temperature steaming, high-pressure carbonization, drying, fine planing, color sorting, assembly and pressing, and sanding. This results in excellent physical properties, including a low coefficient of water absorption and expansion, resistance to cracking and deformation. It is a three- or multi-layered board material glued together with adhesives, usually using an odd number of veneer layers, with the fiber directions of adjacent veneers perpendicular to each other. It is a commonly used material in furniture making. After gluing and pressing, excess glue on the edges of the plywood needs to be scraped off.

[0003] For example, Chinese patent with authorization announcement number "CN215542994U" discloses a plywood adhesive scraping device, including a workbench, a conveyor belt installed on one side of the workbench, and a placement plate connected to the top of the conveyor belt. An installation frame is installed on the top of the workbench; an installation plate is connected to one side of the installation frame, and a first bolt is threadedly connected to one side of the installation plate. The first bolt passes through the installation plate and is rotatably connected to a scraper. This application is prior art compared to this application. However, during the process of scraping adhesive from the side of plywood, excess adhesive may be squeezed and flow to the upper and lower sides of the plywood, and it is difficult to scrape it off completely using only a vertically set scraper. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a multi-layer bamboo board scraping device that can scrape off excess adhesive around the edges after pressing and gluing multi-layer bamboo boards.

[0005] This utility model is implemented by the following method: a multi-layer bamboo board glue scraping device, including an operating table, with support rods provided at both the left and right ends of the rear side of the upper surface of the operating table, a support plate provided on the upper surface of the support rods, and first telescopic cylinders provided at both the left and right ends of the lower surface of the support plate. A limit pressing plate is provided at the end of the telescopic rod of the first telescopic cylinder, and glue scraping parts for realizing the glue scraping function of multi-layer bamboo boards are provided around the limit pressing plate.

[0006] Furthermore, the adhesive scraping component includes an adhesive scraper. The limiting pressure plate has strip-shaped openings around its perimeter. A drive motor is embedded in each strip-shaped opening. The output end of the drive motor is connected to a screw. A moving block is spirally sleeved on the screw. A second telescopic cylinder is embedded in the moving block. An L-shaped block is provided at the end of the telescopic rod of the second telescopic cylinder. A third telescopic cylinder is embedded on the vertical plate of the L-shaped block. A fixing plate is provided at the end of the telescopic rod of the third telescopic cylinder. The adhesive scraper is provided on the inner side of the fixing plate.

[0007] The beneficial effects of this utility model are as follows: This utility model incorporates a limiting pressing plate and a glue scraper into the device, enabling the pressing of multi-layer bamboo boards. Furthermore, the glue scraper effectively removes excess glue from the sides of the multi-layer bamboo boards, facilitating centralized glue removal. In this glue scraping device for plywood, the limiting pressing plate presses down on the multi-layer bamboo boards during the scraping process, ensuring tight adhesion between the layers and expelling excess glue from the sides of the multi-layer bamboo boards, thus facilitating the scraping process. This utility model has a simple structure, is easy to operate, and effectively saves manpower and resources, improving work efficiency. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] Please see Figure 1 and Figure 2 As shown, this utility model provides an embodiment: a multi-layer bamboo board glue scraping device, including an operating table 1. Support rods 2 are provided at both ends of the rear side of the upper surface of the operating table 1. A support plate 3 is provided on the upper surface of the support rods 2. First telescopic cylinders 4 are provided at both ends of the lower surface of the support plate 3. A limiting pressure plate 5 is provided at the end of the telescopic rod of the first telescopic cylinder 4. Glue scraping components 6 are provided around the limiting pressure plate 5 to achieve the glue scraping effect on the multi-layer bamboo board. This allows the first telescopic cylinder 4 to drive the limiting pressure plate 5 to move up and down, achieving the pressing and limiting of the multi-layer bamboo board. Then, through the action of the glue scraping components 6, excess glue overflowing from the sides of the multi-layer bamboo board can be scraped off.

[0012] Please continue reading. Figure 1 and Figure 2As shown in one embodiment of this utility model, the glue scraper 6 includes a glue scraper 61. The limiting and pressing plate 5 has strip-shaped openings 62 around its perimeter. A drive motor (not shown) is embedded within each strip-shaped opening 62. The output end of the drive motor is connected to a screw 63. A moving block 64 is spirally fitted onto the screw 63. A second telescopic cylinder 65 is embedded in the moving block 64. An L-shaped block 66 is provided at the end of the telescopic rod of the second telescopic cylinder 65. A third telescopic cylinder 67 is embedded on the vertical plate of the L-shaped block 66. A fixing plate 68 is provided at the end of the telescopic rod of the third telescopic cylinder 67. The glue scraper 61 is located on the inner side of the fixing plate 68. This allows the drive motor to rotate the screw 63, thereby moving the moving block 64 back and forth. The second telescopic cylinder 65 moves the L-shaped block 66 up and down. Then, the third telescopic cylinder 67 moves the fixing plate 68, allowing the glue scraper 61 to contact the side of the multi-layer bamboo board and remove excess glue.

[0013] The drive motor, telescopic cylinder, and scraper blade in this invention are all existing technologies, which are already well understood by those skilled in the art, and will not be described in detail here.

[0014] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
