[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-9 A pneumatic suction feeder for producing wood-plastic sound-absorbing panels provided in an embodiment of the present invention comprises a bottom plate frame 1, which is in a rectangular structure, and rectangular grooves are respectively arranged on the left and right sides of the bottom plate frame 1; a conveying platform 2, which is two in number, and the two conveying platforms 2 are respectively installed in the rectangular grooves on the left and right sides of the bottom plate frame 1, and the conveying platform 2 is used to uniformly convey the wood-plastic sound-absorbing panel, and a limiting frame 21 is installed on the inner end of the conveying platform 2; a conveying component 3, which is installed in the middle of the upper end of the bottom plate frame 1, and the conveying component 3 and the two conveying platforms 2 are arranged in a cross shape, and an embossing station is arranged between the conveying component 3 and the side wall of the conveying platform 2, and a workbench 22 is arranged on the embossing station, and the workbench 22 is installed on the bottom plate frame 1; a material taking component 4, which is installed at the upper end of the conveying component 3, and the material taking component 4 is configured to suck the wood-plastic sound-absorbing panel on the conveying platform 2 and convey the wood-plastic sound-absorbing panel to the embossing station.

[0031] In the above technical solution, the injection molded wood-plastic sound-absorbing board is placed on the conveying platform 2, and the conveying platform 2 drives the wood-plastic sound-absorbing board to move at a uniform speed. When the wood-plastic sound-absorbing board moves to the inner side of the conveying platform 2, the limiting frame 21 will limit the wood-plastic sound-absorbing board, so that the position of the wood-plastic sound-absorbing board remains consistent after each transmission. After that, the conveying component 3 drives the material taking component 4 to reciprocate. When the material taking component 4 moves to the upper end of the conveying platform 2, the material taking component 4 moves downward to absorb and take the material of the wood-plastic sound-absorbing board. When the material taking is completed, the conveying component 3 drives the material taking component 4 to place the wood-plastic sound-absorbing board on the embossing station, and the surface of the wood-plastic sound-absorbing board is embossed by the embossing equipment.

[0032] It should be noted that after injection molding, the surface of the wood-plastic sound-absorbing board is often relatively smooth. In order to increase the sound absorption effect, the wood-plastic sound-absorbing board often needs to be embossed. By applying a certain pressure and temperature on the surface of the wood-plastic sound-absorbing board, a certain concave and convex texture is produced on the surface, increasing the surface area of ​​the sound-absorbing board, thereby improving the sound absorption effect.

[0033] See also Figure 1-Figure 2 As shown, as a preferred technical solution of this embodiment, the conveying assembly 3 includes a connecting frame 31, a rotating rod 32, a limiting rod 33 and a movable platform 34. The connecting frame 31 is fixed at the middle part of the upper end of the base frame 1, and a mounting groove is arranged at the middle part of the upper end of the connecting frame 31. The upper end of the connecting frame 31 is symmetrically provided with slide grooves. The rotating rod 32 is installed inside the mounting groove through a bearing, and an external thread is arranged on the rotating rod 32. A threaded block is connected to the rotating rod 32 by threaded matching. The limiting rod 33 is fixedly installed in the slide groove, and a slider is slidably arranged on the limiting rod 33. The movable platform 34 is a rectangular structure, and the lower end of the movable platform 34 is connected to the threaded block and the slider.

[0034] In the above technical solution, the end of the rotating rod 32 is connected to the output shaft of the motor. When the motor is working, the motor drives the rotating rod 32 to rotate, and the rotating rod 32 drives the movable platform 34 to reciprocate through the threaded block, so that the movable platform 34 can drive the material taking component 4 to move along the length direction of the connecting frame 31, which is convenient for the material taking and placing processing of the wood-plastic sound-absorbing board.

[0035] See also Figure 3-Figure 9 As shown, as a preferred technical solution of this embodiment, the material taking component 4 includes a connecting plate 41, a pneumatic mechanism 42 and a suction mechanism 43. The connecting plate 41 is installed on the upper end of the movable platform 34, and the pneumatic mechanism 42 is installed on the upper end of the connecting plate 41. The number of the suction mechanisms 43 is two, and the two suction mechanisms 43 are respectively installed on the left and right sides of the lower end of the pneumatic mechanism 42. The pneumatic mechanism 42 drives the suction mechanism 43 to adsorb and fix the surface of the wood-plastic sound-absorbing board.

[0036] In the above technical solution, when the wood-plastic sound-absorbing board is taken, the air pressure mechanism 42 drives the suction mechanism 43 to move downward and closely adhere to the surface of the wood-plastic sound-absorbing board. The suction mechanism 43 can accurately absorb and fix the porous wood-plastic sound-absorbing board, which is convenient for the suction and feeding of the wood-plastic sound-absorbing board and beneficial to the subsequent processing of the wood-plastic sound-absorbing board.

[0037] It should be noted that the wood-plastic sound-absorbing board is a high-tech green and environmentally friendly new decorative material mainly made of wood (wood cellulose, plant cellulose) as the base material, thermoplastic polymer materials (plastics) and processing aids, which are evenly mixed and then heated and extruded by mold equipment. The surface of the wood-plastic sound-absorbing board is a uniform porous structure, and the ordinary adsorption method cannot accurately adsorb the surface of the wood-plastic sound-absorbing board. The suction mechanism 43 seals the holes on the wood-plastic sound-absorbing board first, and then adsorbs the wood-plastic sound-absorbing board by adsorption, so as to achieve the function of accurately absorbing and feeding the wood-plastic sound-absorbing board.

[0038] Continuing to refer to Figure 4, as a preferred technical solution of this embodiment, the pneumatic mechanism 42 includes a guide rail 421, a mounting plate 422, a sliding plate 423 and a cylinder 424. There are multiple guide rails 421, which are evenly installed on the upper end of the connecting plate 41. The mounting plate 422 is installed between the upper ends of the guide rails 421. The sliding plate 423 is a rectangular structure. The sliding plate 423 is evenly provided with through holes that match the guide rails 421. Linear bearings are installed on the through holes. The sliding plate 423 is slidably connected to the guide rail 421 through the linear bearing. A telescopic spring is provided on the guide rail 421 at the lower end of the sliding plate 423. Cylinders 424 are evenly installed between the mounting plate 422 and the sliding plate 423. The cylinder 424 is configured to drive the suction mechanism 43 to be in close contact with the surface of the wood-plastic sound-absorbing board through the sliding plate 423.

[0039] In the above technical solution, when the suction mechanism 43 moves to the top of the wood-plastic sound-absorbing board, the cylinder 424 drives the sliding plate 423 to move downward, so that the sliding plate 423 can drive the suction mechanism 43 to be in close contact with the surface of the wood-plastic sound-absorbing board, and the telescopic spring plays a buffering role; when the suction mechanism 43 is adsorbed on the surface of the wood-plastic sound-absorbing board, the cylinder 424 drives the sliding plate 423 to move upward, which is convenient for subsequent processing of the wood-plastic sound-absorbing board.

[0040] See also Figure 5As shown, as a preferred technical solution of this embodiment, the suction mechanism 43 includes a connecting column 431, a fixed template 432, a movable mold frame 433, a buffer 434, a sliding frame 435 and an adsorption unit 436. The connecting column 431 is a cylindrical structure, a pneumatic groove is arranged in the middle of the connecting column 431, the connecting column 431 is installed at the lower end of the sliding plate 423, a fixed template 432 is fixedly installed at the lower end of the connecting column 431, the fixed template 432 is a rectangular structure, a movable mold frame 433 is arranged below the fixed template 432, buffers 434 are evenly installed between the fixed template 432 and the movable mold frame 433, the movable mold frame 433 is a rectangular frame structure, rectangular grooves are evenly arranged on the movable mold frame 433, a sliding frame 435 is installed in the rectangular groove, the upper end of the sliding frame 435 is connected to the fixed template 432, an adsorption unit 436 is installed inside the sliding frame 435, and the adsorption unit 436 is connected to the pneumatic groove through a connecting hose.

[0041] In the above technical solution, when the air pressure mechanism 42 drives the connecting column 431 to move downward, the movable mold frame 433 first contacts the upper surface of the wood-plastic sound-absorbing board, and the buffer member 434 can play a buffering role to prevent the movable mold frame 433 from rigidly contacting the surface of the wood-plastic sound-absorbing board. After that, the fixed template 432 drives the sliding frame 435 to continue to move downward. The adsorption unit 436 in the middle of the sliding frame 435 can swing arbitrarily in the horizontal plane when the lower end is squeezed, so that the lower end of the adsorption unit 436 can accurately match the hole on the wood-plastic sound-absorbing board, and then the function of sealing the hole on the wood-plastic sound-absorbing board first and then adsorbing and fixing the wood-plastic sound-absorbing board by adsorption can be realized, and the absorption effect is good, and the wood-plastic sound-absorbing board can be prevented from being damaged during the absorption and feeding process.

[0042] See also Figure 6-7 As shown, as a preferred technical solution of this embodiment, the buffer member 434 includes a telescopic column fixedly installed on the upper end of the movable mold frame 433 and a guide hole cooperating with the telescopic column, the guide hole is arranged at the lower end of the fixed template 432, and a buffer spring is sleeved on the outer side of the telescopic column.

[0043] In the above technical solution, the buffer spring can effectively play a buffering role, avoiding direct rigid contact between the sliding frame 435 and the surface of the WPC sound absorbing board, preventing damage to the surface of the WPC sound absorbing board, and improving the use effect of the WPC sound absorbing board.

[0044] See also Figure 8As shown, as a preferred technical solution of this embodiment, the adsorption unit 436 includes a pneumatic part 4361, an adsorption plate 4362, a sealing part 4363 and an air storage bag 4364. An adsorption plate 4362 is arranged in the middle of the sliding frame 435. The adsorption plate 4362 is of a rectangular structure. An annular cavity is arranged between the outer side of the adsorption plate 4362 and the sliding frame 435. A pneumatic part 4361 is installed inside the annular cavity. The pneumatic part 4361 is used to drive the adsorption plate 4362 to adjust at any angle in the horizontal plane. Circular holes are evenly arranged on the adsorption plate 4362, and sealing parts 4363 are installed in the circular holes. The sealing parts 4363 correspond to the adsorption holes on the wood-plastic sound-absorbing board one by one. An air storage bag 4364 is installed on the upper end of the adsorption plate 4362, and the air storage bag 4364 is connected to the sealing part 4363.

[0045] In the above technical solution, when the sliding frame 435 moves downward, the sliding frame 435 drives the adsorption plate 4362 to move synchronously. Since the wood-plastic sound-absorbing board has a certain deviation in the limiting frame 21, when the adsorption plate 4362 descends, the sealing member 4363 cannot be accurately inserted into the hole on the surface of the wood-plastic sound-absorbing board. At this time, the adsorption plate 4362 can be driven by the pneumatic member 4361 to shake arbitrarily in the plane, so that the sealing member 4363 at the lower end of the adsorption plate 4362 can be accurately inserted into the hole on the surface of the wood-plastic sound-absorbing board. After that, the gas inside the air storage bag 4364 is passed into the sealing member 4363. 4363, so that the sealing member 4363 can accurately block the holes on the surface of the wood plastic sound absorbing board, and then the surface of the wood plastic sound absorbing board at the lower end of the adsorption plate 4362 is a flat sealing surface, and the adsorption plate 4362 can realize the function of adsorbing and fixing the wood plastic sound absorbing board by negative pressure adsorption. At the same time, the sealing member 4363 can expand with the holes on the surface of the wood plastic sound absorbing board, so that the sealing member 4363 and the holes on the surface of the wood plastic sound absorbing board can be pressed and matched, and then the adsorption and fixing effect of the wood plastic sound absorbing board can be further improved, and the phenomenon of the wood plastic sound absorbing board falling off during the moving feeding process can be avoided.

[0046] See also Fig. 9 As shown, as the preferred technical solution of this embodiment, the pneumatic part 4361 is made of rubber material, and the pneumatic part 4361 is a rectangular hollow structure. Pneumatic cavities are evenly arranged inside the pneumatic part 4361, and the pneumatic cavities are connected to the high-pressure gas through valves. Connecting rods are evenly arranged inside the pneumatic part 4361, and the connecting rods are respectively connected to the adsorption plate 4362 and the sliding frame 435 through pins, and the connecting rods are used to keep the adsorption plate 4362 moving in the horizontal direction.

[0047] In the above technical solution, the pneumatic cavity is connected to the high-pressure gas through a valve, and the amount of gas entering the pneumatic cavity is controlled by the high-pressure gas. By expanding and contracting the multiple pneumatic cavities arranged in the middle of the pneumatic part 4361, the adsorption plate 4362 can be adjusted at any angle, so that the sealing part 4363 at the lower end of the adsorption plate 4362 can be accurately inserted into the hole on the surface of the wood-plastic sound-absorbing board.

[0048] It should be noted that the shaking range of the pneumatic part 4361 has a certain amplitude, that is, the range of the shaking of the adsorption plate 4362 driven by the pneumatic part 4361 is the spacing between adjacent holes on the surface of the wood-plastic sound-absorbing board, so that when the adsorption plate 4362 is shaking, the sealing part 4363 at the lower end of the adsorption plate 4362 can be accurately inserted into the hole on the surface of the wood-plastic sound-absorbing board.

[0049] See also Figure 8 As shown, as a preferred technical solution of this embodiment, the sealing member 4363 includes a plug-in column 4365, a plug-in rod 4366 and a sealing airbag 4367. The plug-in column 4365 is installed in the circular hole. The middle part of the plug-in column 4365 is a hollow structure. The upper end of the plug-in column 4365 is connected to the air bag 4364. The plug-in rod 4366 is installed at the lower end of the plug-in column 4365. An annular groove is provided between the upper end of the plug-in rod 4366 and the plug-in column 4365. The sealing airbag 4367 is installed in the annular groove. The sealing airbag 4367 is connected to the air bag 4364 through the plug-in column 4365.

[0050] In the above technical solution, when the lower end of the plug rod 4366 is inserted into the hole on the surface of the wood-plastic sound-absorbing board, the gas inside the air storage bag 4364 flows outward into the sealing air bag 4367, and the sealing air bag 4367 expands outward to press and seal the hole on the surface of the wood-plastic sound-absorbing board, thereby accurately blocking and sealing the hole on the surface of the wood-plastic sound-absorbing board, which is beneficial to the subsequent absorption and feeding of the wood-plastic sound-absorbing board.

[0051] See also Figure 8 As shown, as a preferred technical solution of this embodiment, the plug-in rod 4366 has a T-shaped structure, the lower end of the plug-in rod 4366 has a conical structure, and the lower end of the plug-in rod 4366 is made of elastic material.

[0052] In the above technical solution, when the adsorption plate 4362 moves downward, the lower end of the plug rod 4366 first contacts the surface of the wood-plastic sound-absorbing board. If the plug rod 4366 is not inserted into the hole on the surface of the wood-plastic sound-absorbing board, the pneumatic part 4361 drives the plug rod 4366 to move arbitrarily in the plane until the plug rod 4366 is inserted into the hole on the surface of the wood-plastic sound-absorbing board.
