Description

Technical Field

[0002] Plastic hollow board is a board extruded from plastic raw materials, with a hollow structure inside, similar to the shape of a honeycomb. This hollow structure makes the board relatively light while maintaining a certain strength. Its wall surface is generally smooth, and different thicknesses are available to meet different usage requirements. When producing plastic hollow boards, in order to prevent impurities from entering the board body during use, the sides of the hollow board need to be sealed. In the field of edge sealing of plastic hollow boards, with the continuous improvement of product quality requirements, the importance of the feeding link has become increasingly prominent.

[0003] In the feeding process of edge sealing of plastic hollow panels, the cleanliness of the surface of the hollow panels has a key impact on the quality of edge sealing.

Manual wiping is inefficient and cannot meet the needs of large-scale production, and fixed dust suction devices have limited effect on cleaning dust and debris on the four sides of the hollow panels. These impurities will be mixed between the edge sealing material and the hollow panel during the edge sealing process, resulting in quality problems such as loose edge sealing and gaps.

[0031] When this embodiment is in use, the second motor 1002 is started, and the second motor 1002 is used to drive the second forward and reverse screw rod 1003 to rotate. The third threaded sleeve 1005 moves under the action of the second forward and reverse screw rod 1003 and the third guide rod 1004, and the connecting roller 1006 moves with the third threaded sleeve 1005 and rolls on the inclined surface of the connecting plate 1008. When the connecting roller 1006 rolls on the inclined surface, it will compress the first spring 1007 to move the connecting plate 1008 downward, and then drive the circular dust suction head 11 to move downward to a position close to the hollow plate through the connecting frame 1009. The external dust suction device is started, and the hollow plate is vacuumed and cleaned by the circular dust suction head 11, thereby removing impurities such as dust and debris on the side wall of the hollow plate, thereby improving the subsequent edge sealing quality. After the vacuuming is completed, the dust suction head can be reset by the opposite operation. Example 3

[0032] Reference Figure 6-7This embodiment is based on the previous embodiment, and is different from the previous embodiment in that the adjustment structure 12 includes a third forward and reverse screw rod 1201, a fourth guide rod 1202, a fourth threaded sleeve 1203 and an active rack 1204, one end of the connecting box 1001 is rotatably connected to the third forward and reverse screw rod 1201, and the third forward and reverse screw rod 1201 penetrates the side wall of the connecting box 1001 and is fixedly connected to the second forward and reverse screw rod 1003, one end of the connecting box 1001 is fixedly connected to the fourth guide rod 1202, and two fourth threaded sleeves 1203 are threadedly connected to the third forward and reverse screw rod 1201, and the bottom end of the fourth threaded sleeve 1203 is fixedly connected to the active rack 1204.

[0033] The limiting structure 13 includes a limiting plate 1301, a rotating shaft 1302, a movable plate 1303, a telescopic rod 1304, a second spring 1305, a horizontal plate 1306, a guide cleaning roller 1307 and a driven gear 1308. The top of the loading platform 1 and both sides of the second groove 8 are fixedly connected with two limiting plates 1301, and the limiting plate 1301 is rotatably connected to the rotating shaft 1302, and the rotating shaft 1302 is fixedly connected to the movable plate 1303, and the bottom end of the movable plate 1303 is fixedly connected to the second groove 8. It is connected to a telescopic rod 1304, and a horizontal plate 1306 is fixedly connected to the bottom end of the telescopic rod 1304, and two second springs 1305 are arranged between the horizontal plate 1306 and the movable plate 1303, a plurality of guide cleaning rollers 1307 are installed at the bottom end of the horizontal plate 1306, and one end of the rotating shaft 1302 passes through the limiting plate 1301 and is fixedly connected to a driven gear 1308, and the driven gear 1308 is placed directly below the active rack 1204, and the driven gear 1308 is meshed with the active rack 1204.

[0034] When this embodiment is in use, the third forward and reverse screw rod 1201 will be driven to rotate during the rotation of the second forward and reverse screw rod 1003, and the fourth threaded sleeve 1203 will move under the action of the third forward and reverse screw rod 1201 and the fourth guide rod 1202, driving the active rack 1204 at the bottom to move. The movement of the active rack 1204 will mesh with the driven gear 1308 in the limiting structure 13, and at the same time, through the connection relationship with the downward pressing structure 10, the adjustment of the downward pressing and limiting functions is realized. When the active rack 1204 moves, it meshes with the driven gear 1308, so that the rotating shaft 1302 rotates, driving the movable plate 1303 to rotate with the rotating shaft 1302, thereby removing the movable plate 1303 and a plurality of guide cleaning rollers 1307 from above the conveying cleaning roller 9, so as to facilitate the subsequent placement of the hollow plate on the conveying cleaning roller 9 for conveying operation.

The pneumatic suction cup 507 adsorbs the hollow plate by generating suction. The suction force can be adjusted according to factors such as the material and weight of the hollow plate to ensure stable adsorption. The hollow plate is then lifted, and the first motor 502 is started. The threaded rod 503 is driven to rotate by the first motor 502, thereby driving the first threaded sleeve 505, the pneumatic suction cup 507 and the hollow plate to move above the plurality of second grooves 8. Example 5

[0037] Reference Figure 8-10 , this embodiment is based on the previous embodiment, and is different from the previous embodiment in that the pushing structure 6 includes a second fixed plate 601, a first forward and reverse screw rod 602, a second guide rod 603, a second threaded sleeve 604, a first movable block 605, a linkage rod 606, a second movable block 607 and a third pushing plate 608, the top of the loading platform 1 is fixedly connected with the second fixed plate 601, one end of the second fixed plate 601 is rotatably connected with the first forward and reverse screw rod 602, one end of the second fixed plate 601 is fixedly connected with the second guide rod 603, and two second threaded sleeves 604 are threadedly connected on the first forward and reverse screw rod 602, and one end of the second threaded sleeve 604 is fixedly connected with the first movable block 605, and the first movable block 605 is rotatably connected with the linkage rod 606, and the end of the linkage rod 606 away from the first movable block 605 is rotatably connected with the second movable block 607, and the end of the second movable block 607 away from the first movable block 605 is fixedly connected with the third pushing plate 608.

[0038] One end of the threaded rod 503 is fixedly connected to a first synchronous wheel 508 , one end of the first forward and reverse threaded rod 602 is fixedly connected to a second synchronous wheel 609 , and a synchronous belt 7 is arranged between the first synchronous wheel 508 and the second synchronous wheel 609 .

[0039] When the present embodiment is in use, the threaded rod 503 rotates, which drives the first synchronous wheel 508 to rotate. With the cooperation of the first synchronous wheel 508, the second synchronous wheel 609 and the synchronous belt 7, the first positive and negative screw rods 602 are driven to rotate, and the two second threaded sleeves 604 are driven to move away from each other. The first movable block 605 at one end of the second threaded sleeve 604 is connected to the second movable block 607 through the linkage rod 606. When the first movable block 605 moves, the linkage rod 606 transmits this movement to the second movable block 607. When the hollow plate moves to the top of the second groove 8, the third push plate 608 moves out of the second groove 8. The hollow plate is placed on the conveying cleaning rollers 9 by the hydraulic cylinder 506 and the pneumatic suction cup 507, and then the second motor 1002 is started to drive the connecting roller 1006 to move out from the connecting plate 1008. At this time, the connecting plate 1008, the connecting frame 1009 and the circular dust collector head 11 move upward under the drive of the first spring 1007.

The second spring 1305 and the cross plate 1306 work together to drive the guide cleaning roller 1307 to limit the hollow plate on both sides. When the guide cleaning roller 1307 contacts the hollow plate, the telescopic rod 1304 and the second spring 1305 will be correspondingly extended and retracted to make the guide cleaning roller 1307 always contact the edge of the hollow plate, thereby guiding and limiting the hollow plate, ensuring that the hollow plate moves in the correct direction during transportation, preventing it from being offset or misaligned, and ensuring the accuracy of edge banding. After the movable plate 1303 is flipped over, the first motor 502 is started to drive the pneumatic suction cup 507 to move to At the top of the first groove 2, the third push plate 608 will push the hollow plates above the conveying cleaning rollers 9 to move smoothly. During the transportation of the plastic hollow plates on the conveying cleaning rollers 9, the guide cleaning rollers 1307 and the conveying cleaning rollers 9 are in contact with the surface of the hollow plates. While limiting and conveying the hollow plates, they can brush off dust, debris and other impurities on the surface, further improving the cleanliness of the surface of the hollow plates, helping to improve the quality of edge banding processing, and preventing impurities from affecting the adhesion effect of the edge banding glue. At the same time, the guide cleaning rollers 1307 limit the hollow plates on both sides, allowing them to move smoothly into the edge banding machine.
