It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] A preferred embodiment of the raw material screening device for composite adhesive production provided by this utility model is, for example... Figures 1 to 5 As shown: A raw material screening device for composite adhesive production includes a base 9; a controller 7 fixedly connected to one side of the front of the base 9; fixing springs 6 fixedly connected to both sides of the top of the base 9; a housing 2 fixedly connected to the bottom of the fixing springs 6; a vibration motor 8 fixedly connected to the bottom of the housing 2; a lower discharge plate 10, a middle discharge plate 11, and an upper discharge plate 12 fixedly connected sequentially from bottom to top on one side of the housing 2; a feed hopper 1 fixedly connected to the other side of the top of the housing 2; a pull-out groove 17 opened on the front of the housing 2; a coarse screen plate 13 and a fine screen plate 14 arranged inside the housing 2; and an installation assembly 3 assembled on the front of the housing 2, which is used to realize the quick assembly and disassembly of the coarse screen plate 13 and the fine screen plate 14.

[0028] It should be noted that some existing raw material screening devices for composite adhesive production still have certain shortcomings in actual use. After long-term use, some materials will get stuck in the holes of the screen plate, requiring symmetrical disassembly and cleaning. At the same time, it is also necessary to replace the screen plate with a different mesh size according to the actual production needs. However, the existing disassembly is inconvenient, which will affect the above operations.

[0029] In this embodiment, the composite binder raw material is added into the housing 2 through the feed hopper 1, and then the vibration motor 8 is started to make the housing 2 vibrate up and down. The raw material is then graded and vibrated through the coarse screen plate 13 and the fine screen plate 14. The larger raw materials are discharged through the upper discharge plate 12 and the middle discharge plate 11, while the smaller raw materials flow to the bottom wall of the housing 2 and are guided by the guide plate 15 to be discharged through the lower discharge plate 10. This achieves the graded vibration screening of the composite binder raw material. At the same time, the installation component 3 can be used to quickly disassemble and assemble the coarse screen plate 13 and the fine screen plate 14, which is convenient for disassembly, maintenance or replacement of coarse screen plate 13 and fine screen plate 14 with different mesh sizes.

[0031] In this embodiment, by actuating the pull rod 302, two sliding blocks 305 slide on the surface of the sliding rod 307, compressing the mounting spring 304 and causing the mounting block 306 to slide until it is completely disengaged from the mounting hole 308. Then, the sealing plate 301 can be pulled to slide out the coarse screen plate 13 and the fine screen plate 14, facilitating maintenance of the coarse screen plate 13 and the fine screen plate 14 or replacement with coarse screen plates 13 and the fine screen plate 14 of different mesh sizes. During installation, the pull rod 302 is first actuated to make the mounting block 306 slide. Then, the coarse screen plate 13 and the fine screen plate 14 are inserted through the pull groove 17, and the slide plate 18 is slid into the slide groove 16. Then, the pull rod 302 is released, and the elastic force of the installation spring 304 is used to make the installation block 306 snap into the installation hole 308, thereby limiting and fixing the sealing plate 301. At the same time, the sealing gasket 309 is used to improve the firmness and sealing of the connection between the sealing plate 301 and the pull groove 17, and to prevent the raw material from getting stuck in the gap between the sealing plate 301 and the pull groove 17.

[0032] In a further preferred embodiment of the present utility model, the sealing plate 301 is convex in shape, and the area of the cross-section at one end of the sealing plate 301 is larger than the area of the cross-section of the opening of the drawing slot 17.

[0033] In this embodiment, by using the larger sealing plate 301, after it is inserted into the inside of the drawing slot 17, the drawing slot 17 can be preliminarily blocked and sealed.

[0034] In a further preferred embodiment of the present utility model, a sealing gasket 309 is fixedly connected to one end of the surface of the sealing plate 301, and the shape of the sealing gasket 309 is a square frame.

[0035] In this embodiment, by using the sealing gasket 309, the firmness and sealing performance of the insertion connection between the sealing plate 301 and the inside of the drawing slot 17 are improved.

[0036] In a further preferred embodiment of the present utility model, a pull rod 302 is fixedly connected between one ends of the sliding blocks 305, and the shape of the pull rod 302 is U-shaped.

[0037] In this embodiment, by using the U-shaped pull rod 302, it is convenient to synchronously drive the sliding of the two sliding blocks 305.

[0040] In a further preferred embodiment of the present utility model, a sliding groove 16 is formed on the inner wall of the housing 2, and sliding plates 18 that are fixedly connected to both sides of the coarse sieve plate 13 and the fine sieve plate 14 are slidably engaged with the inside of the sliding groove 16.

[0041] In this embodiment, by using the sliding of the sliding plates 18 and the inside of the sliding groove 16, the sliding disassembly and assembly of the coarse sieve plate 13 and the fine sieve plate 14 are realized.

[0042] In a further preferred embodiment of the present utility model, a material guiding plate 15 is fixedly connected to the inner bottom wall of the housing 2, and the inclination angle of the top end of the material guiding plate 15 with respect to the horizontal direction is 20 degrees.

[0043] In this embodiment, by using the inclined material guiding plate 15, the finally screened and dropped raw materials can be guided, making it easier to discharge through the lower discharge plate 10.

[0044] In a further preferred embodiment of this utility model, slide rods 4 are fixedly connected to both sides of the top of the base 9, and sliders 5 that slide in cooperation with the surface of the slide rods 4 are fixedly connected to the lower ends of the front and back sides of the housing 2.

[0045] In this embodiment, the smoothness of vibration of the housing 2 is improved by utilizing the sliding of the slider 5 and the surface of the slider 4.

[0047] In this embodiment, the inclined coarse screen plate 13 and fine screen plate 14 are used to make it easier to discharge the larger raw materials screened out.

[0048] In summary, by using the vibrating motor 8, the coarse screen plate 13, and the fine screen plate 14, the composite binder raw materials can be vibrated and graded for screening, thereby improving the screening efficiency. At the same time, the installation component 3 facilitates the disassembly of the coarse screen plate 13 and the fine screen plate 14 for maintenance or replacement with coarse screen plates 13 and the fine screen plate 14 of different mesh sizes to meet the screening and production needs of different composite binder raw materials.
