[0012] Figure 1 It is a schematic diagram of a furniture board edge banding machine, in which the bed board has been placed in the conveying gap.
[0013] Figure 2 This is a schematic diagram of a furniture board edge banding machine, in which the mounting block, slide rail, motor slider and drive motor are removed. DETAILED DESCRIPTION
[0014] The present invention is further described in detail below in conjunction with specific implementation methods.
[0015] Furniture board edge banding machine Figure 1 , including a bottom plate 8, on which two upper and lower conveying units 1 and 5 are installed, and the two conveying units 1 and 5 constitute the conveying mechanism of the furniture board edge banding machine. The upper and lower conveying units 1 and 5 have the same structure, and the upper conveying unit 1 is taken as an example. Figure 2The bottom plate 8 is fixedly mounted with front and rear support blocks 81 and 82, and the upper conveying unit 1 is respectively mounted with front and rear pairs of guide posts 311 and 312 in the front and rear directions on the front and rear support blocks 81 and 82, the front guide post 311 extends backward, and the rear guide post 312 extends forward. The upper conveying unit 1 is respectively mounted with front and rear sliders 321 and 322 on the front and rear pairs of guide posts 311 and 312, and the front and rear rotating shafts 341 and 342 are rotatably mounted on the front and rear sliders 321 and 322, and the front and rear sprockets 11 and 12 are respectively mounted on the front and rear rotating shafts 341 and 342, and the metal chains 13 are sleeved on the outer sides of the front and rear sprockets 11 and 12, and the conveying belt 14 is fixedly mounted on the outer side of the chain 13. The front and rear guide posts 311, 312 serve as guides, and the front and rear sliders 321, 322 can slide forward and backward along the front and rear guide posts 311, 312, respectively. The upper conveying unit 1 is provided with front and rear tension springs 331, 332 in a stretched state on the outside of the front and rear guide posts 311, 312, respectively. The front tension spring 331 has a front end fixedly connected to the front support block 81, and a rear end fixedly connected to the front slider 321, and applies a forward pulling force to the front slider 321 to make the front slider 321 slide forward along the front guide post 311; the rear end of the rear tension spring 332 is fixedly connected to the rear support block 82, and a front end fixedly connected to the rear slider 322, and applies a backward pulling force to the rear slider 322 to make the rear slider 322 slide backward along the rear guide post 312; in this way, the front and rear tension springs 331, 332 drive the front and rear sliders 321, 332. 22 move away from each other. Since the front and rear sliders 321 and 322 are respectively connected to the front and rear sprockets 11 and 12 by the front and rear rotating shafts 341 and 342, the front and rear sliders 321 and 322 move away from each other, which drives the front and rear rotating shafts 341 and 342 to move away from each other, thereby driving the front and rear sprockets 11 and 12 to move away from each other. The front and rear sprockets 11 and 12 jointly tighten the chain 13 so that the chain 13 and the conveyor belt 14 are tightened together, and the tightened chain 13 pulls the two sprockets 11 and 12 in the opposite direction. The front and rear guide pillars 311 and 312, the front and rear sliders 321 and 322 and the front and rear springs 331 and 332 together constitute a zipper assembly. Figure 1 The bottom plate 8 is installed with two front and rear mounting blocks 83 and 84. The upper conveying unit 1 includes a slide rail 35 in the front and rear directions. The front and rear ends of the slide rail 35 are respectively fixedly connected to the front and rear mounting blocks 83 and 84. A motor-mounted slider 36 is slidably installed on the slide rail 35. A driving motor 37 is installed on the motor-mounted slider 36. The driving motor 37 is connected to the rear rotating shaft 342. The rear sprocket 12 can be indirectly driven to rotate by driving the rear rotating shaft 342 to drive the chain 13 to move, thereby driving the conveying belt 14 to move. The lower conveying unit 5 has the same structure as the upper conveying unit 1 and is not described in detail. A horizontal conveying gap 141 is left between the two conveying belts 14 of the upper and lower conveying units 1 and 5, and an existing edge sealing mechanism 2 is provided on the side of the two conveying belts 14.
[0016] When using Figure 1 The bed board 9, as the furniture board to be edge-sealed, is horizontally placed in the horizontal conveying gap 141 from the back to the front. The two conveying belts 14 of the upper and lower conveying units 1 and 5 clamp the bed board 9 together, one above and one below. The two driving motors 37 of the upper and lower conveying units 1 and 5 drive the two conveying belts 14 to move respectively. The two conveying belts 14 jointly send the bed board 9 forward. During this process, the side edge 91 of the bed board 9 passes through the edge-sealing mechanism 2, and the edge-sealing mechanism 2 performs edge sealing on the side edge 91 of the bed board 9. Since the upper and lower conveying units 1 and 5 contact the bed board 9 through the softer conveying belts 14, the harder metal chains 13 do not directly contact the bed board 9, and it is not easy to cause damage to the surface of the bed board 9. When edge banding the side edge 91 of the bed board 9, the edge banding mechanism 2 may need to use a tool to trim or scrape the bed board 9. During this process, the side edge 91 of the bed board 9 will be subjected to the force from the tool. The edge banding machine uses the conveyor belts 14 of the upper and lower conveying units 1 and 5 to clamp the bed board 9 for conveyance, and the bed board 9 is not easy to deviate after being subjected to force. When the sprockets 11 and 12 pull the chain 13 for a long time, causing the chain 13 and the conveyor belt 14 to be stretched together, the two sprockets 11 and 12 can automatically tighten the chain 13. Specifically, when the chain 13 becomes loose, it cannot pull the front and rear sprockets 11 and 12. Since the front tension spring 331 applies a forward elastic force to the front slider 321 and the rear tension spring 332 applies a backward elastic force to the rear slider 322, the front and rear sprockets 11 and 12 will automatically move away from each other until the two sprockets 11 and 12 tighten the chain 13 again to make the chain 13 taut. In this state, the conveyor belt 14 fixed outside the chain 13 is tightened together, and the tightened conveyor belt 14 can transport the bed board normally.
[0017] In this embodiment, see Figure 2 The front tension spring 331 applies a forward pulling force to the front slider 321, and the rear tension spring 332 applies a backward pulling force to the rear slider 322, thereby driving the front and rear sliders 321 and 322 away from each other. In other embodiments, a compression spring in a compressed state may be provided instead, see Figure 1 The front end of the compression spring is fixedly connected to the front slider 321, and the rear end is fixedly connected to the rear slider 322, respectively applying forward and backward thrusts to the front slider 321 and the rear slider 322, thereby driving the front and rear sliders 321 and 322 away from each other.
[0018] In this embodiment, see Figure 2 , the transmission units 1 and 5 are provided with guide posts 311 and 312, sliders 321 and 322 and tension springs 331 and 332 at the front and rear sides. In other embodiments, the transmission units 1 and 5 are only provided with guide shafts, sliders and tension springs at the front and rear sides, for example, see Figure 1The transmission units 1 and 5 are only provided with a rear guide column 312, a rear slider 322 and a rear tension spring 332 on the rear side. The front sprocket 11 is rotatably mounted on the base plate 8 through an existing support frame (not shown in the figure). The rear tension spring 332 applies a backward pulling force to the rear slider 322 to drive the rear sprocket 12 backward away from the front sprocket 11, thereby tightening the chain 13.
[0019] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
