Description

Technical Field

[0001] This utility model relates to particleboard manufacturing, and more particularly to a mechanism for removing edge material during installation. Background Technology

[0002] Particleboard is a type of board made by pressing together layers of wood chips that have been mixed with adhesive and laid in layers. The wood chips are laid on a conveyor belt, and the loose material at the edges of the resulting particleboard strip (the edge material) is suitable for removal.

[0003] Existing technology uses a scraper to remove the shavings, meaning the scraper must contact the conveyor belt to effectively remove fine shavings from its surface. However, this method is not ideal in removing shavings, as the shavings and the scraper together abrade the conveyor belt. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems mentioned above, and to provide a paving edge material removal mechanism to improve the removal rate of paving edge materials and reduce the wear of the conveyor belt.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pavement edge removal mechanism includes a suction nozzle with its opening facing downward toward the edge of a conveyor belt, the suction nozzle being adapted to remove pavement edge material from the edge of the conveyor belt.

[0007] Compared with the prior art, the beneficial effects of this application include: fine wood shavings can be fully removed, improving the rejection rate of paving edge material; the suction nozzle can be separated from the conveyor belt, reducing the wear of the suction nozzle and paving edge material on the conveyor belt, and improving the service life of the conveyor belt.

[0008] As an improvement to the above technical solution, the mouth part of the suction nozzle is inclined relative to the conveyor belt, and the suction port of the suction nozzle is obliquely opposite to the conveying direction of the conveyor belt.

[0009] As an improvement to the above technical solution, the lower lip of the suction nozzle does not intersect the edge of the conveyor belt perpendicularly, and the lower lip of the suction nozzle is suitable for removing large wood shavings from the edge of the conveyor belt.

The suction nozzle and the guide plate are arranged sequentially along the transmission direction of the conveyor belt. The guide plate intersects the edge of the conveyor belt in a non-perpendicular manner. The guide plate is suitable for removing residual paving material that has already been suctioned from the edge of the conveyor belt.

[0011] As an improvement to the above technical solution, a collection trough is also included, which is suitable for collecting the paving edge material dislodged by the suction nozzle and / or the guide plate.

[0012] As an improvement to the above technical solution, multiple dust-blocking inclined plates are arranged at intervals in the middle of the collection trough, so that the inner cavity of the collection trough is divided into an upper cavity and a lower cavity. The gap between the multiple dust-blocking inclined plates is suitable for allowing the paving edge material to fall into the lower cavity, and the dust-blocking inclined plates are suitable for reducing the outward dust from the lower cavity.

[0013] As an improvement to the above technical solution, it also includes a bracket, a slide, and an adjusting screw. The slide is adapted to install the suction nozzle, the slide is slidably connected to the bracket, and is connected to the bracket through the adjusting screw.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 This utility model provides a pavement edge material removal mechanism, including a suction nozzle 100. The suction nozzle 100 is suitable for connecting to a suction device, such as a fan or pump. A filter, such as a filter bag or filter cartridge, may even be connected in series between the suction device and the suction nozzle 100. The suction force / power of the suction device is adjusted according to different wood shavings. The suction port 111 of the suction nozzle 100 faces downward toward the edge of the conveyor belt 700. The suction nozzle 100 is suitable for sucking up the pavement edge material at the edge of the conveyor belt 700.

[0031] Compared with the prior art, the beneficial effects of this application include: fine wood shavings can be fully removed, improving the rejection rate of paving edge material; the suction nozzle 100 can be separated from the conveyor belt 700, reducing the wear of the suction nozzle 100 and paving edge material on the conveyor belt 700, and improving the service life of the conveyor belt 700.

[0032] In some designs, the suction port 111 faces downwards vertically directly towards the conveyor belt 700. (Refer to...) Figure 1 , Figure 2 In some embodiments of this utility model, the mouth part 110 of the suction nozzle 100 is inclined relative to the conveyor belt 700, that is, the suction port 111 is obliquely downward facing the conveyor belt 700, and the suction port 111 of the suction nozzle 100 is obliquely opposite to the conveying direction of the conveyor belt 700. (Refer to...) Figure 1 and Figure 2The suction nozzle 100 includes a mouth part 110 and a connecting part 120 connected together. The mouth part 110 is inclined relative to the conveyor belt 700, and the connecting part 120 is adapted to connect to the suction device. The paving edge material approaches the suction port 111 of the suction nozzle 100 with forward conveying inertia. Combined with the suction of the paving edge material by the suction nozzle 100 to the front and top, the paving edge material can be sucked up and fly into the suction nozzle 100 before it touches the lips of the suction nozzle 100, and the paving edge material is fully and quickly sucked away.

[0033] Furthermore, the nozzle 100 is angled at the mouth 110, allowing the lower lip of the nozzle 100 to be higher than the conveyor belt 700. Larger wood shavings can be sucked up and either fly or roll into the nozzle 100. When a large number of larger wood shavings accumulate at the edge of the conveyor belt 700, any remaining larger wood shavings that are not promptly sucked into the nozzle 100 can escape below the nozzle 100, preventing the larger wood shavings from being jammed between the nozzle 100 and the conveyor belt 700. To prevent material jamming, the guide plate 200 described below can be used.

[0034] In some designs, the mouthpiece 110 of the suction nozzle 100 is tilted or vertical, and the lower lip of the suction nozzle 100 is closer to the conveyor belt 700. The distance D between the conveyor belt 700 and the lower lip of the suction nozzle 100 is 1mm ≤ D ≤ 12mm; preferably, 1mm ≤ D ≤ 12mm. In some designs, the lower lip of the suction nozzle 100 is higher than the conveyor belt 700, with a distance of 12mm ≤ D ≤ 28mm.

[0035] To address the issue of slightly larger wood shavings that have escaped the suction nozzle (100mm), refer to... Figure 1 , Figure 2 Furthermore, it also includes a guide plate 200, a suction nozzle 100 and the guide plate 200 arranged sequentially along the transmission direction of the conveyor belt 700. The guide plate 200 intersects the edge of the conveyor belt 700 in a non-perpendicular manner. The guide plate 200 is suitable for removing residual paving material that has been suctioned from the edge of the conveyor belt 700.

[0036] In some designs, the lower lip of the suction nozzle 100 is closer to the conveyor belt 700. The lower lip of the suction nozzle 100 does not intersect the edge of the conveyor belt 700 perpendicularly. The lower lip of the suction nozzle 100 is suitable for removing large wood shavings from the edge of the conveyor belt 700.

[0037] Reference Figure 1 , Figure 2 In some embodiments of this utility model, a collection trough 300 is also included, which is adapted to collect the paving edge material removed by the suction nozzle 100 and / or the guide plate 200.

[0038] Reference Figure 1 , Figure 2Preferably, multiple dust-blocking inclined plates 310 are arranged at intervals in the middle of the collection trough 300, so that the inner cavity of the collection trough 300 is divided into an upper cavity and a lower cavity. The gap between the multiple dust-blocking inclined plates 310 is suitable for allowing the paving edge material to fall into the lower cavity, and the dust-blocking inclined plates 310 are suitable for reducing the outward dust from the lower cavity.

[0039] Reference Figures 1 to 3 In some embodiments of this utility model, the suction port 111 of the mouth 110 is flat and small and the throat is wide. The upper lip of the suction port 100 is deviated from the lip sidewall to form the upper expansion area of ​​the suction port 111. The inclined "substantial suction port" combined with the suction port 111 with the "upward lip" does not change the actual mouth area of ​​the mouth 110 in its axial direction. When the substantial mouth sucks in large-mouth wood shavings, it is smoother and less likely to jam.

[0040] In some embodiments of this utility model, the suction nozzle 100 is connected to the suction device through a corrugated tube. The corrugated tube is adapted to bend as needed. The suction nozzle 100 is detachably connected to the corrugated tube. One end of the suction nozzle 100 connected to the corrugated tube is adapted to clean the inside of the suction nozzle 100.

[0041] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the system further includes a bracket 400, a slide 500, and an adjusting screw 600. The slide 500 is adapted to mount the suction nozzle 100. The slide 500 is slidably connected to the bracket 400 and connected to the bracket 400 via the adjusting screw 600. The adjusting screw 600 is adapted to drive the suction nozzle 100 to move laterally along the conveyor belt 700 to adjust the depth of the suction nozzle 100 on the wood shavings. It can be understood that one of the slide 500 and the bracket 400 is rotatably connected to the adjusting screw 600, and the other is threadedly connected to the adjusting screw 600.

[0042] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the carriage 500 includes a slider 510 and a mounting plate 520. The mounting plate 520 is suitable for mounting the suction nozzle 100 and the guide plate 200. The upper end of the bracket 400 is provided with a groove 410 suitable for the slider 510 to slide. The slider 510 is supported by the groove 410 and can be detachably hung on the mounting plate 520. (See reference...) Figure 1 and Figure 2 The mounting plate 520 has a mounting hole for screw mounting of the suction nozzle 100. The mounting rod of the guide plate 200 passes upward through the mounting plate 520, and a nut is tightened on the upper end of the mounting rod of the guide plate 200.

[0043] The ease of disassembly and assembly of the carriage 500 and the adjusting screw 600 remains unresolved; refer to... Figure 1 , Figure 2In some embodiments of this utility model, it also includes a thrust plate 610, an adjusting screw 600 threadedly connected to a slide 500 and rotatably connected to a bracket 400, an adjusting screw 600 integrally formed with a thrust shoulder, and a thrust plate 610 adapted to a detachable ferrule adjusting screw 600. The thrust shoulder and the thrust plate 610 together grip the bracket 400 to limit the movement of the adjusting screw 600 relative to the bracket 400.

[0044] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the bracket 400 is provided with a scale mark 420, and the slide 500 is provided with a pointer 511. The scale mark 420 and the pointer 511 are adapted to jointly indicate the depth of the suction nozzle 100 on the wood shavings.
