[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the embodiment, Figure 1-6 A dust-free processing production line for core panels of fireproof doors is provided, comprising a shell 1, a conveyor belt 2 is provided inside the shell 1, an extrusion switch 3 is provided inside the shell 1, a limit assembly 4 is provided inside the shell 1 on the side opposite to the extrusion switch 3, a rolling assembly 5 is provided on the limit assembly 4, a lifting assembly 6 is provided at the top inner top of the shell 1, a rolling shutter door 7 is provided on the lifting assembly 6, a cleaning assembly 8 is provided at the top inner top of the shell 1, and dust collection assemblies 9 are provided on both sides of the interior of the shell 1.

[0028] Reference Figure 2-6 , wherein the limiting assembly 4 includes a telescopic cylinder 41, the telescopic cylinder 41 located on the top of the conveyor belt 2 is fixedly installed inside the housing 1, and the telescopic end of the telescopic cylinder 41 is fixedly installed with a limiting plate 42;

[0029] Through the above-mentioned structural setting, when the door core panel is driven by the conveyor belt 2 to near the exit, the telescopic cylinder 41 is started and the telescopic cylinder 41 drives the limit plate 42 to move forward to limit the door core panel, so that the side surfaces of the door core panels of different sizes are always in a fit state with the extrusion switch 3, which facilitates the door core panel to trigger the extrusion switch 3 during the movement.

[0030] Reference Figure 6 The rolling assembly 5 includes a mounting groove 51. The mounting groove 51 is opened on the side of the limit plate 42 facing the squeeze switch 3. A spring 52 is fixedly installed inside the mounting groove 51. The other end of the spring 52 is fixedly connected to a roller 53. The roller 53 is slidably installed inside the mounting groove 51.

[0031] Through the above-mentioned structural setting, when the limiting plate 42 squeezes and limits the door core plate, the roller 53 allows the door core plate to continue to move when it is limited, and the spring 52 provides a certain buffer space to prevent the door core plate from being squeezed by the limiting plate 42 and unable to move.

[0032] Reference Figure 2-5 , wherein the lifting assembly 6 includes a reduction motor 61, the reduction motor 61 is fixedly installed inside the housing 1, the output end of the reduction motor 61 is fixedly installed with a rotating rod 62, a sprocket 63 is symmetrically installed on the rotating rod 62, the sprocket 63 is fixedly connected to the chain 64, the other end of the chain 64 is fixedly connected to the rolling door 7, and the rolling door 7 is slidably installed inside the housing 1;

[0033] Through the above-mentioned structural setting, when the squeezing switch 3 is triggered by the squeezing of the door core plate, the signal is transmitted to the reduction motor 61, and the reduction motor 61 starts to drive the rotating rod 62 to rotate. The rotating rod 62 rotates while driving the sprocket 63 to rotate. The chain 64 is wrapped around the outside of the sprocket 63 as it rotates, and at the same time drives the rolling shutter door 7 to rise, so that the rolling shutter door 7 is stored outside the sprocket 63. When the door core plate is removed to release the squeezing of the squeezing switch 3, the reduction motor 61 reverses to make the rolling shutter door 7 drop and close, so as to prevent the internal wood chips from floating out.

[0034] Reference Figure 2-3 , wherein the cleaning assembly 8 includes a drive motor 81, the drive motor 81 is fixedly installed on the top of the inner portion of the housing 1, a screw rod 82 is fixedly installed on the output end of the drive motor 81, a screw rod slider 83 is threadedly connected to the screw rod 82, and a cleaning brush 84 is fixedly installed on the bottom of the screw rod slider 83;

[0035] Through the above-mentioned structural setting, after the door core board is processed, some wood chips will remain on the surface of the door core board. Start the drive motor 81, and the drive motor 81 drives the screw rod 82 to move. When the screw rod 82 rotates, it drives the screw slider 83 to move back and forth. During the movement, the screw slider 83 drives the cleaning brush 84 to clean the wood chips on the surface of the door core board into the dust collection assembly 9 on both sides of the door core board to maintain the cleanliness of the door core board surface.

[0036] Reference Figure 2-4 , wherein the dust collection assembly 9 includes a receiving hopper 91, and the housing 1 is fixedly installed with receiving hoppers 91 located on both sides of the conveyor belt 2, and the bottoms of the two receiving hoppers 91 are connected to the dust collector 92;

[0037] With the above-mentioned structural arrangement, the vacuum cleaner 92 is started, and the suction force generated by the vacuum cleaner 92 is transmitted to the interior of the housing 1 through the receiving hopper, so that the wood chips are sucked from the receiving hopper 91 into the interior of the vacuum cleaner 92 and the wood chips are collected.

[0038] Working principle:

[0039] Implementation steps for the first innovation point:

[0040] Step 1: The door core board after processing is moved along the conveyor belt 2, and then the vacuum cleaner 92 is started. The suction force generated by the vacuum cleaner 92 is transmitted to the inside of the shell 1 through the receiving hopper, and the wood chips are sucked into the vacuum cleaner 92 from the receiving hopper 91 to collect the wood chips. At the same time, the drive motor 81 is started, and the drive motor 81 drives the screw rod 82 to move. When the screw rod 82 rotates, it drives the screw rod slider 83 to move back and forth. During the movement, the screw rod slider 83 drives the cleaning brush 84 to clean the wood chips on the surface of the door core board into the dust collection components 9 on both sides of the door core board to keep the surface of the door core board clean;

[0041] Step 2: When the door core plate moves to the discharge port of the shell 1, the telescopic cylinder 41 is started. The telescopic cylinder 41 drives the limit plate 42 to move forward to limit the door core plate, so that the side surfaces of door core plates of different sizes are always in a fit state with the extrusion switch 3, which is convenient for the door core plate to trigger the extrusion switch 3 during movement. When the extrusion switch 3 is triggered by the extrusion of the door core plate, the signal is transmitted to the reduction motor 61, and the reduction motor 61 starts to drive the rotating rod 62 to rotate. While the rotating rod 62 rotates, it drives the sprocket 63 to rotate. The chain 64 is wound around the outside of the sprocket 63 as it rotates, and at the same time drives the rolling shutter door 7 to rise, so that the rolling shutter door 7 is stored outside the sprocket 63. When the door core plate is taken out to release the extrusion on the extrusion switch 3, the reduction motor 61 reverses to make the rolling shutter door 7 drop and close, preventing internal wood chips from floating out.
