Description

Technical Field

[0001] The utility model belongs to the technical field of plywood grinding, and particularly relates to a plywood grinding device. Background Art

[0002] Plywood, also known as splint, blockboard, three-ply board, five-ply board, is a composite wood made by bonding wood chips, wood fibers or joinery slices with an adhesive. It is also an economical and widely used building and furniture material. Compared with ordinary wood, plywood has the advantages of light weight, clear texture, insulation, high strength, not easy to deform, convenient construction, not easy to warp, and good transverse tensile mechanical properties.

[0003] The production process of plywood generally includes: veneer peeling, glue coating, embryo forming, cold pressing, hot pressing and sanding. Among them, sanding refers to sanding and grinding the surface of the board to remove burrs on the surface of the plywood to ensure the processing quality of the plywood. The existing grinding of plywood is generally manually completed, but manual grinding of plywood has the problems of low grinding efficiency and high labor intensity. At the same time, there will also be dust debris during the grinding of plywood, and these dust debris are easily inhaled by the staff, which is likely to cause harm to the staff's body.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a plywood grinding device.

[0005] The information disclosed in this background art section is only for increasing the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a plywood grinding device, which can solve the problems of manual grinding of plywood.

[0007] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0008] A plywood grinding device, comprising: a conveyor belt, a grinding cover and a processing mechanism;

[0009] The grinding cover is installed on the conveyor belt. The grinding cover is provided with a feed inlet and a discharge outlet.

A driving motor and a plurality of grinding rollers are installed on the base. The driving motor is connected to the grinding rollers through a belt drive;

[0010] The processing mechanism is installed on the grinding cover. The processing mechanism includes an air extraction pump. The suction end of the air extraction pump is connected with a filtering mechanism. Air suction pipes are installed on both sides of the base. A plurality of evenly distributed suction nozzles are connected to the air suction pipes. A connecting pipe is connected between a pair of the air suction pipes. An air inlet pipe is connected between the connecting pipe and the filtering mechanism.

[0011] In one or more embodiments of the present utility model, the number of the grinding rollers is three. The three grinding rollers are drivingly connected by a belt. When the driving motor operates, the driving motor can drive one of the grinding rollers to rotate. The rotating grinding roller can drive the other grinding rollers to rotate through the belt, so as to grind the plywood conveyed on the conveyor belt.

[0012] In one or more embodiments of the present utility model, a straight pipe is installed on one side wall of the grinding cover. The straight pipe is arranged above the feed inlet.

[0013] In one or more embodiments of the present utility model, a plurality of evenly distributed spraying nozzles are installed on the straight pipe. The plurality of spraying nozzles are vertically downward. The gas sucked by the air extraction pump is conveyed to the straight pipe through a connecting pipe. The gas in the straight pipe is then ejected through the plurality of spraying nozzles. When the plywood passes through the feed inlet, the gas can dry the surface of the plywood so that the plywood can be better ground. At the same time, the gas can also form an air curtain at the feed inlet, so that the dust and debris in the grinding cover are not easily wafted outside the grinding cover through the feed inlet, creating a good working environment for the staff.

[0014] In one or more embodiments of the present utility model, a connecting pipe is connected between the straight pipe and the air outlet end of the processing mechanism. The gas sucked by the air extraction pump can be conveyed to the straight pipe through the connecting pipe.

[0015] In one or more embodiments of the present utility model, a mounting plate is installed on one side wall of the grinding cover. A plurality of evenly distributed blocking strips are connected to the mounting plate. The blocking strips correspond to the discharge outlet. The blocking strips can block the discharge outlet, so that the dust and debris in the grinding cover are not easily wafted outside the grinding cover through the discharge outlet.

[0016] In one or more embodiments of the present utility model, the blocking strips are made of rubber material.

[0017] In one or more embodiments of the present utility model, the filtering mechanism includes a filtering box. A pair of grid frames are installed in the filtering box, which are used for filtering the gas entering the filtering box from the grinding cover and also for fixing the filter cotton.

[0018] A filter cotton is arranged between the pair of grid frames. The filter cotton is used for filtering the gas and removing the dust and debris in the gas, so that the dust and debris are not easily affected the air extraction pump.

[0019] In one or more embodiments of the present utility model, a baffle is installed in the filter box. The baffle is disposed on the lower side of the wire mesh frame and corresponds to the intake pipe. The gas in the polishing hood enters the filter box through the intake pipe and diffuses under the blocking action of the baffle, so as to improve the utilization rate of the wire mesh frame and the filter cotton, and prevent the gas from concentrating and passing through the wire mesh frame and the filter cotton. At the same time, when the air pump stops running, it can also prevent dust debris from flowing back through the intake pipe.

[0020] In one or more embodiments of the present utility model, a cleaning port is provided on the side wall of the filter box. The cleaning port corresponds to the filter cotton, which is convenient for cleaning the dust debris in the filter box and replacing the filter cotton.

[0021] Compared with the prior art, a plywood polishing device of the present utility model can polish plywood, which can not only improve the polishing efficiency of plywood and reduce the burden on workers, but also prevent the dust debris generated during plywood polishing from floating, creating a good working environment for workers.

Detailed implementation manners

[0032] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0033] As Figures 1 to 7 shown, a plywood grinding device in an embodiment of the present utility model includes a conveyor belt 1, a grinding cover 2 and a processing mechanism 3.

[0034] Among them, the conveyor belt 1 is used to convey plywood so as to perform grinding treatment on the plywood.

[0035] As Figures 1 to 7 shown, the grinding cover 2 is installed on the conveyor belt 1. The grinding cover 2 is used to install the base 204, the drive motor 205 and the grinding roller 206, so that the plywood can be in a relatively enclosed space during grinding, thereby reducing the probability of dust and debris floating and creating a good working environment for the staff.

[0036] Among them, the grinding cover 2 is provided with a feed inlet 201 and a discharge outlet 202. The plywood enters the grinding cover 2 from the feed inlet 201 and is then conveyed out of the grinding cover 2 through the discharge outlet 202.

[0037] In addition, a telescopic member 203 is installed on the inner top wall of the grinding cover 2. By the telescoping of the telescopic member 203, the lifting of the base 204 can be controlled so that the grinding roller 206 can grind the surface of the plywood.

[0038] Specifically, the free end of the telescopic member 203 is connected to a base 204, and a driving motor 205 and a plurality of grinding rollers 206 are installed on the base 204. The driving motor 205 may be an AF110.180 high-speed motor produced by Dongguan Aofeng Motor Co., Ltd. The driving motor 205 is connected to the grinding rollers 206 through a belt transmission. When the driving motor 205 is running, the driving motor 205 can drive one of the grinding rollers 206 to rotate through the belt.

[0039] Preferably, there are three grinding rollers 206, and the three grinding rollers 206 are connected by belts. When the driving motor 205 is running, the driving motor 205 can drive one of the grinding rollers 206 to rotate, and the rotating grinding roller 206 can drive other grinding rollers 206 to rotate through the belt. The plywood conveyed on the conveyor belt 1 can be polished by using multiple rotating grinding rollers 206, thereby improving the polishing efficiency of the plywood and reducing the burden on the staff.

[0040] like Figures 1 to 7 As shown, a straight pipe 207 is installed on one side wall of the polishing cover 2, and the straight pipe 207 is arranged on the upper side of the feed port 201. A number of uniformly distributed injection heads are installed on the straight pipe 207, and a number of injection heads are vertically downward. The gas sucked by the vacuum pump 301 is transported to the straight pipe 207 through the connecting pipe 208, and the gas in the straight pipe 207 is then ejected through a number of injection heads. When the plywood passes through the feed port 201, the gas can dry the surface of the plywood so that the plywood can be polished better. At the same time, the gas can also form an air curtain at the feed port 201, so that the dust and debris in the polishing cover 2 are not easy to float outside the polishing cover 2 through the feed port 201, creating a good working environment for the staff.

[0041] A connecting pipe 208 is connected between the straight pipe 207 and the gas outlet end of the processing mechanism 3 , and the gas sucked by the vacuum pump 301 can be transported to the straight pipe 207 through the connecting pipe 208 .

[0042] In addition, a mounting plate 209 is installed on one side wall of the polishing cover 2, and a plurality of evenly distributed baffles 210 are connected to the mounting plate 209. The baffles 210 are made of rubber material and correspond to the discharge port 202. The baffles 210 can shield the discharge port 202, so that the dust and debris in the polishing cover 2 are not easy to float outside the polishing cover 2 through the discharge port 202.

[0043] like Figures 1 to 7 As shown, the processing mechanism 3 is installed on the polishing cover 2, and the processing mechanism 3 is used to process the dust and debris in the polishing cover 2, so that the dust and debris are not easy to float outside the polishing cover 2, creating a good working environment for the staff.

[0044] Among them, the processing mechanism 3 includes an air extraction pump 301. The air extraction pump 301 can be a 35L piston negative pressure pump. The suction end of the air extraction pump 301 is connected to a filtering mechanism 302. The filtering mechanism 302 is used to filter the gas, remove dust debris in the gas, so as to centrally process the dust debris, and at the same time make it difficult for the dust debris to affect the air extraction pump 301.

[0045] In addition, the filtering mechanism 302 includes a filtering box 3021. A pair of grid frames 3022 are installed in the filtering box 3021. The grid frames 3022 are used to filter the gas entering the filtering box 3021 from the grinding cover 2, and at the same time are used to fix the filter cotton 3023.

[0046] Specifically, filter cotton 3023 is provided between a pair of grid frames 3022. The filter cotton 3023 is used to filter the gas, remove dust debris in the gas, and make it difficult for the dust debris to affect the air extraction pump 301.

[0047] Furthermore, a baffle 3024 is installed in the filtering box 3021. The baffle 3024 is located on the lower side of the grid frame 3022 and corresponds to the air inlet pipe 306. The gas in the grinding cover 2 enters the filtering box 3021 through the air inlet pipe 306 and diffuses under the blocking action of the baffle 3024, so as to improve the utilization rate of the grid frame 3022 and the filter cotton 3023, and make it difficult for the gas to pass through the grid frame 3022 and the filter cotton 3023 concentratedly. At the same time, when the air extraction pump 301 stops running, it can also make it difficult for the dust debris to backflow through the air inlet pipe 306.

[0048] Moreover, a cleaning port 3025 is provided on the side wall of the filtering box 3021. The cleaning port 3025 corresponds to the filter cotton 3023, which is convenient for cleaning the dust debris in the filtering box 3021 and replacing the filter cotton 3023.

[0049] As Figures 1 to 7 shown, air suction pipes 303 are installed on both sides of the base 204. A number of evenly distributed suction heads 304 are connected to the air suction pipes 303. A connecting pipe 305 is connected between a pair of air suction pipes 303. An air inlet pipe 306 is connected between the connecting pipe 305 and the filtering mechanism 302. When the air extraction pump 301 operates, the air extraction pump 301 makes the filtering box 3021 form a negative pressure. The filtering box 3021 makes the air suction pipes 303 form a negative pressure through the air inlet pipe 306 and the connecting pipe 305. The gas in the grinding cover 2 enters the air suction pipes 303 through the suction heads 304 under the action of the negative pressure, and then enters the filtering box 3021. The grid frame 3022 and the filter cotton 3023 are used for filtering.

[0050] During specific use, the driving motor 205 and the air extraction pump 301 are operated. The driving motor 205 can drive one of the grinding rollers 206 to rotate through a belt. The rotating grinding roller 206 can then drive the other grinding rollers 206 to rotate synchronously through a belt. When the air extraction pump 301 is operated, a negative pressure is formed inside the filter box 3021. The filter box 3021 causes a negative pressure to be formed inside the suction pipe 303 through the intake pipe 306 and the connecting pipe 305. The gas inside the grinding cover 2 enters the suction pipe 303 through the suction head 304 under the action of the negative pressure, and then enters the filter box 3021.

[0051] The plywood to be ground is placed on the conveyor belt 1 for conveyance. The plywood enters the grinding cover 2 through the feed inlet 201. When the plywood passes through the feed inlet 201, the gas sucked by the air extraction pump 301 is conveyed to the straight pipe 207 through the connecting pipe 208, and the gas inside the straight pipe 207 is then ejected through a number of spray heads. The gas can dry the surface of the plywood so that the plywood can be ground better. At the same time, the gas can also form an air curtain at the feed inlet 201, making it difficult for the dust and debris inside the grinding cover 2 to float outside the grinding cover 2 through the feed inlet 201, creating a good working environment for the staff.

[0052] When the plywood enters the grinding cover 2, the telescopic member 203 extends, causing the base 204, the driving motor 205, and the grinding rollers 206 to descend. A number of rotating grinding rollers 206 can grind the surface of the plywood, thereby improving the grinding efficiency of the plywood and reducing the burden on the staff. The dust and debris generated during grinding float inside the grinding cover 2. Since the suction pipe 303 is in a negative pressure state, the dust and debris inside the grinding cover 2 will be sucked and conveyed to the filter box 3021, where they are filtered by the wire mesh 3022 and the filter cotton 3023, making it difficult for the dust and debris to float outside the grinding cover 2 and creating a good working environment for the staff.

[0053] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
