Description

Technical Field

[0001] The utility model relates to the technical field of sheet processing, and more specifically, the utility model relates to a sander for surface treatment of a core board. Background Art

[0002] A core board is a sheet with super-strong and super-light performance, mainly including an upper panel, a lower panel, and a sandwich layer disposed between the two. The sandwich layer can be a honeycomb array, an array of hollow tubes arranged at intervals, or a corrugated board array, etc. The core board can be widely used in the fields of architecture, road and bridge, wind power, vehicles, ships, airplanes, vacuum tunnels, etc. At present, when processing the core board, it is necessary to sand the surface of the core board. Sanding can, on the one hand, calibrate the thickness of the core board, and on the other hand, improve the flatness of the surface of the core board.

[0003] It has been found that currently, most of the sanding equipment for processing core boards uses a sanding belt to sand the surface of the core board. The core board is sanded by placing it on the driven sanding belt (the driven sanding belt has the same transmission principle as the existing belt conveyor, except that the sanding belt replaces the conveyor belt). When the core board reaches the end of the sanding belt, the transmission power of the sanding belt will accelerate the blanking of the core board. Therefore, when the core board falls to the ground, it is easy to cause damage to the structure. In addition, when the core board is subjected to double-sided sanding treatment, it is necessary for workers to closely follow the end of the sanding belt to collect the core board and at the same time deal with the debris on the core board, which is rather troublesome.

Specific embodiments

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Refer to in combination Figures 1 - 4, the utility model provides a sanding machine for surface treatment of core plates, which includes a base 1, a conveying unit 2 arranged on the base 1, and a sanding belt 3 drivingly connected to the conveying unit 2. In this application, the conveying unit 2 can use a belt conveyor without a conveyor belt in the prior art to control the transmission of the sanding belt 3. For example, the conveying unit 2 is composed of structures such as a frame, idler rollers, drums, a tensioning device, and a transmission device to cooperate with the sanding belt 3 for sanding transmission. By utilizing the characteristics of the material of the sanding belt 3, the core plate is placed on the sanding belt 3 and subjected to a pressing treatment, so that the surface of the core plate can be sanded. Above the sanding belt 3, there is a pressing seat 4, and at least three pressing rollers 5 are rotatably connected to the pressing seat 4. A lifting mechanism 7 is arranged on the pressing seat 4 and the base 1. The pressing rollers 5 can be used to press the core plate tightly against the sanding belt 3 for sanding. When the pressing rollers 5 rotate, they rotate counterclockwise and at a speed lower than the running speed of the sanding belt 3.

[0024] On the pressing seat 4, there is a driving device 6 for driving the pressing rollers 5 to rotate. The driving device 6 can adopt a rotating motor. By controlling the pressing rollers 5 to rotate through the driving device 6, the stability of the core plate moving and sanding on the sanding belt 3 can be improved.

[0025] The lifting mechanism 7 includes a lifting device 71. The lifting device 71 is fixedly connected to the base 1. A pair of slide rails 72 are fixedly connected to the base 1. A lifting frame 73 is fixedly connected to the pair of slide rails 72. The lifting frame 73 is fixedly connected to the pressing seat 4. The output end of the lifting device 71 is fixedly connected to the lifting frame 73. The lifting device 71 can adopt a lifting motor, which can provide lifting power for the pressing rollers 5, so as to adapt to core plates of different thicknesses for pressing treatment.

[0026] On one side of the base 1, there is a bracket 8 fixedly connected. Inside the bracket 8, there are multiple elastic connectors 9 fixedly connected. The elastic connectors 9 adopt a spring structure. The elastic connectors 9 can increase the vibration amplitude when the material guiding inclined plate 10 vibrates. A material guiding inclined plate 10 is fixedly connected to the multiple elastic connectors 9. A sieve plate 101 is fixedly embedded in the material guiding inclined plate 10. A vibration device 102 is fixedly connected to the bottom of the material guiding inclined plate 10. The vibration device 102 can adopt a vibration motor. A material guiding inclined groove 103 is opened on the base 1, and the material guiding inclined groove 103 corresponds to one side of the material guiding inclined plate 10.

[0027] The slope of the material guiding inclined plate 10 is the same as that of the material guiding inclined groove 103. The material guiding inclined groove 103 runs through the base 1. The advantage of this design is that when the core plate after sanding treatment falls onto the material guiding inclined plate 10, the core plate can pass through the base 1 through the material guiding inclined groove 103, so that workers can quickly pick up the core plate for sanding treatment on the other side without collecting and taking it at the end of the sanding belt 3.

[0028] A rubber plate one 11 is fixedly connected to the upper surface of the material guiding inclined plate 10. A rubber plate two 12 is arranged on the side of the rubber plate one 11. The rubber plate two 12 is arranged on one side of the end of the sanding belt 3. A buffer assembly 13 is arranged on the rubber plate two 12 and the bracket 8.

[0029] The sieve plate 101 is located at the lower side position of the rubber plate one 11. A blanking groove is formed on the bracket 8. The blanking groove is arranged at the lower position of the sieve plate 101. The arrangement of the blanking groove can provide a discharge channel for the wood chips screened by the sieve plate 101.

[0030] It should be noted that in order to avoid the burden of debris screening on the sieve plate 101, a dust collecting device, such as a dust collecting box, can be arranged at the end of the sanding belt 3, which is not shown in the figure. This can avoid sanding dust and prevent debris from falling onto the material guiding inclined plate 10.

[0031] The number of the buffer assemblies 13 is at least two. The buffer assembly 13 includes a support one 131, the support one 131 is fixedly connected to the bracket 8. A sliding rod 132 penetrates through and is slidably connected to the support one 131. The sliding rod 132 is arranged in a T-shaped structure. One end of the sliding rod 132 is fixedly connected to a mounting plate 133. The rubber plate two 12 is fixedly connected to the mounting plate 133. A buffer spring 134 is sleeved on the sliding rod 132, and the two ends of the buffer spring 134 are respectively fixedly connected to the opposite surfaces of the support one 131 and the mounting plate 133.

[0032] A damping pad 14 is fixedly connected to the sliding rod 132. The damping pad 14 is in movable contact with the support one 131. The damping pad 14 can inhibit the jumping of the buffer spring 134.

[0033] When the utility model is in use, the pressing roller 5 is adjusted to a reasonable pressing height through the lifting mechanism 7. Then, the core board can be placed on the sanding belt 3 manually. The conveying unit 2 provides transmission power for the sanding belt 3 by using the structural principle of the existing belt conveyor. In this way, the surface of the core board can be sanded on the sanding belt 3. When the core board moves to the end of the sanding belt 3 and is sent out, in order to avoid the impact force of the core board during blanking being accelerated due to the driving speed of the sanding belt 3, a rubber plate one 11 and a rubber plate two 12 are arranged on the blanking path of the core board. The core board can first contact the rubber plate two 12. The rubber plate two 12 made of rubber can provide flexible buffering for the core board. The impact force of the core board acting on the rubber plate two 12 can be further unloaded by the sliding rod 132 sliding on the support one 131 and the buffer spring 134 sleeved on the sliding rod 132. In this way, the impact force of the core board during blanking can be reduced. The rubber plate one 11 can further provide buffering for the buffered and falling core board. In this way, the protection of the core board during blanking can be maximized;

[0034] Meanwhile, by starting the vibration device 102, its working vibration can be transmitted to the material guiding inclined plate 10 elastically connected to the bracket 8. By virtue of the inclined arrangement of the material guiding inclined plate 10 and the sieve plate 101 embedded therein, the core board can move on the guiding inclined plate 10 towards the material guiding chute 103, facilitating manual picking up of the core board at the leading end position of the sanding belt 3. Therefore, while promoting the downward sliding of the core board and providing convenience for its movement towards the leading end of the sanding belt 3, the vibration mode in cooperation with the sieve plate 101 can promote the cleaning of debris on the core board, and by optimizing the steps of manual processing of the core board, the efficiency of double-sided sanding of the core board can be increased.
