Description

Technical Field

[0001] This invention relates to the field of particleboard production technology, specifically to a particleboard particle flow regulating device. Background Technology

[0002] In the existing technology, a wood shaving machine is a machine specifically designed to produce wood shavings. It can shave wood into thin sheets of a certain thickness and push the produced wood shavings out of the machine. When in use, it is connected to an external conveying device to transport the wood shavings to subsequent particleboard production equipment, which then processes the wood shavings into particleboard for later use.

[0003] In the wood processing industry, wood shaving machines are an important production piece of equipment responsible for processing wood into wood shavings. However, existing wood shaving machine designs have certain limitations in the process of producing wood shavings and conveying them to subsequent particleboard production equipment. Wood shaving machines only perform the function of shaving wood, and the structure at the shaving outlet is generally quite simple. This makes it impossible to accurately control the flow rate of shavings after shaving. In this case, the deviation in the output shavings flow rate will cause a phenomenon of significant local disparities in the number of shavings on the conveying equipment. During the process of conveying the shavings to the particleboard production equipment, the imbalance in the number of shavings leads to uneven distribution of shavings inside the board. This situation will negatively affect the production quality of particleboard, causing fluctuations in product quality, thereby reducing the stability of particleboard production quality and affecting the competitiveness of particleboard in the market.

That is, the amount of wood chips used can be effectively controlled when feeding wood chips, so that the amount of wood chips used in subsequent particleboard production and processing remains consistent, thereby improving the production efficiency of wood chips, reducing the production time and cost caused by uneven wood chip supply, and ensuring that the raw material quality of each particleboard is consistent, avoiding the situation where the product quality fluctuates and becomes unstable due to insufficient or excessive wood chips.

[0022] (3) By setting the inner wall scraping mechanism, the inner ring wall of the feeding pipe can be scraped and cleaned repeatedly, reducing the shaving residue on the inner wall of the feeding pipe, keeping the inner ring wall of the feeding pipe clean, reducing pipe blockage and accumulation, and avoiding shaving backflow, ensuring normal feeding and subsequent processing of shavings, and keeping the shaving flow rate consistent each time, thereby improving the stability and consistency of the subsequent production quality of particleboard.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Embodiments of the present invention

[0037] Please refer to Figures 1 to 7 As shown, a particleboard shavings flow rate regulating device includes a frame 1, a shaving machine body 2 mounted on the frame 1, and a fixed frame 3 fixedly connected to the middle of the frame 1. The particleboard shavings flow rate regulating device includes a quantitative conveying mechanism, an outer wall tapping mechanism, and an inner wall scraping mechanism. The quantitative conveying mechanism, the outer wall tapping mechanism, and the inner wall scraping mechanism are all mounted on the fixed frame 3, and the quantitative conveying mechanism is located between the fixed frame 3 and the shaving machine body 2.

[0038] The quantitative conveying mechanism is used to quantitatively convey the wood shavings produced by the wood shaving machine body 2. The quantitative conveying mechanism includes a wood shaving conveying cylinder 401 set above the fixed frame 3. A feed pipe 402 is vertically and fixedly connected to the outer surface of the end of the wood shaving conveying cylinder 401 facing the wood shaving machine body 2. The end of the feed pipe 402 away from the wood shaving conveying cylinder 401 is fixedly connected to the wood shaving machine body 2. A discharge pipe 403 is vertically and fixedly connected to the outer surface of the end of the wood shaving conveying cylinder 401 away from the feed pipe 402.

[0039] The outer wall striking mechanism is used to reciprocate striking the outer walls of the material transfer pipe 402 and the discharge pipe 403;

[0040] The inner wall scraping mechanism is used to reciprocate scraping the inner wall of the feed pipe 403;

[0041] The quantitative conveying mechanism also includes a drive motor 404 fixedly connected to the outer surface of the end of the wood shaving conveying cylinder 401 facing the material conveying pipe 402. The output end of the drive motor 404 is fixedly connected to a rotating shaft 405, and a spiral blade 406 is fixedly connected to the outer surface of the rotating shaft 405.

[0042] The end of the rotating shaft 405 away from the drive motor 404 passes through the wood shavings conveying cylinder 401 and is fixedly connected to the turntable 408. A lever 409 is fixedly connected off-center on the side of the turntable 408 away from the wood shavings conveying cylinder 401.

[0043] Please refer to Figure 3 Even better: the spiral blades 406 are disposed inside the wood shavings conveying cylinder 401, and the spiral blades 406 have the same pitch, so that the same amount of wood shavings can be transported.

[0044] The effects achieved by this embodiment are as follows: Compared with the prior art, the quantitative conveying mechanism can convey the falling wood shavings in equal quantities, thereby ensuring that the wood shavings are evenly distributed during transportation. This avoids the phenomenon of excessive wood shavings accumulation in some areas and insufficient wood shavings supply in other areas. In other words, it can effectively control the amount of wood shavings used when feeding the wood shavings, so that the amount of wood shavings used in subsequent particleboard production and processing remains consistent. This improves the production efficiency of wood shavings, reduces the production time and cost caused by uneven wood shavings supply, and ensures that the raw material quality of each particleboard is consistent, avoiding fluctuations and instability in product quality due to insufficient or excessive wood shavings.

[0045] Further examples:

[0046] Please refer to Figures 1 to 7 As shown, the outer wall tapping mechanism includes a first linkage frame 501 slidably connected to the outer surface of the lever 409. Z-shaped toothed plates 502 are symmetrically fixedly connected to both sides of the first linkage frame 501. A support plate 407 is symmetrically fixedly connected vertically downward between the outer surface of the shavings conveying cylinder 401 and the fixed frame 3. Ear plates 503 are symmetrically fixedly connected to the support plate 407, and a torsion spring shaft 504 is rotatably connected between the two parallel and close ear plates 503.

[0047] A striking plate 505 is fixedly connected to the outer surface of both ends of the torsion spring shaft 504, and the striking plates 505 are symmetrically arranged on both sides of the material transfer tube 402 and the discharge tube 403. The striking plates 505 are used to reciprocate to strike the outer wall of the material transfer tube 402 and the discharge tube 403.

[0048] The end of the torsion spring shaft 504 away from the drive motor 404 passes through the ear plate 503 and is fixedly connected to the gear 506;

[0049] A first limiting frame 507 is symmetrically fixedly connected to the outer surface of the end of the wood shaving conveyor 401 away from the drive motor 404, and a first linkage frame 501 is slidably connected between the first limiting frames 507.

[0050] Please refer to Figure 5 Even better: Gear 506 meshes and is properly matched with Z-shaped toothed plate 502. The lateral movement of Z-shaped toothed plate 502 can serve as the power source for gear 506, driving gear 506 to rotate. Torsion spring shaft 504 is composed of torsion spring and central shaft. When gear 506 is driven to rotate, torsion spring shaft 504 rotates synchronously. When the power source for driving gear 506 disappears, the torsion spring's elastic force can cause gear 506 to rotate in the opposite direction and return to its initial state.

[0051] The effects achieved by this embodiment are as follows: Compared with the prior art, the outer wall tapping mechanism can promote the downward movement of wood shavings, making the falling shavings more loose, thereby ensuring the uniformity and stability of planing quality, improving the processing accuracy and surface quality of the product, and the loose shavings can also maintain good flowability of the wood shavings, thereby reducing the occurrence of shavings clumping, keeping the material pipeline unobstructed, avoiding the need for machine shutdown to clean blockages, improving material feeding efficiency, and ensuring the continuity and stability of production.

[0052] A further embodiment:

[0053] Please refer to Figures 1 to 7 As shown, the inner wall scraping mechanism includes a second linkage frame 601 slidably connected to the outer surface of the lever 409, and a first linkage frame 501 is disposed between the second linkage frame 601 and the turntable 408. A second limiting frame 602 is symmetrically fixedly connected to the fixed frame 3, and the second limiting frame 602 is disposed on the same side as the second linkage frame 601. The second linkage frame 601 is slidably connected between the second limiting frames 602.

[0054] A positioning plate 606 is also fixedly connected to the fixed frame 3, and the positioning plate 606 is located below the second linkage frame 601. A slide rod 604 is slidably connected through the positioning plate 606. A pressure plate 603 is fixedly connected to the top of the slide rod 604, and the pressure plate 603 is in contact with the bottom surface of the second linkage frame 601. A return spring 605 is fixedly connected between the pressure plate 603 and the positioning plate 606.

[0055] A connecting frame 607 is fixedly connected to the bottom of the slide rod 604, and a cleaning ring 608 is slidably connected to the inner ring wall of the discharge pipe 403. The cleaning ring 608 is fixedly connected to the connecting frame 607 and fits against the inner wall of the discharge pipe 403.

[0056] Please refer to Figure 4 Even better: the first linkage frame 501 is a vertical bar, the second linkage frame 601 is a horizontal bar, and both the first linkage frame 501 and the second linkage frame 601 slide on the outside of the lever 409. Under the action of the rotation of the lever 409, the first linkage frame 501 moves horizontally left and right, and the second linkage frame 601 moves vertically up and down. This makes it easier to drive the cleaning ring 608 to move up and down on the inner ring wall of the feed pipe 403 to clean the inner ring wall of the feed pipe 403 and reduce the residue and adhesion of wood shavings.

[0057] The effects achieved by this embodiment are as follows: Compared with the prior art, the inner wall scraping mechanism can achieve reciprocating scraping and cleaning of the inner ring wall of the feed pipe 403, reduce the shaving residue on the inner wall of the feed pipe 403, keep the inner ring wall of the feed pipe 403 clean, reduce pipe blockage and accumulation, and prevent shaving backflow, ensuring normal feeding and subsequent processing of shavings, and making the shaving flow rate of each feeding consistent, thereby improving the stability and consistency of the subsequent production quality of particleboard.

[0058] The complete usage steps and working principle of the above embodiments are as follows:

[0059] It should be noted that the wood shaving machine body 2 consists of a shell, a motor, a transmission wheel, a transmission belt, shaving blades, and a feed inlet. The shell is connected to the feed pipe 402 in the quantitative conveying mechanism. The motor, through the transmission wheel and transmission belt, is connected to the shaving blades inside the shell as the driving source for the shaving blades. When shaving wood, the operator can push the wood into the feed inlet so that the wood comes into contact with the shaving blades. The high-speed rotation of the shaving blades shavings the wood. The produced shavings enter the shaving conveyor cylinder 401 through the feed pipe 402 and are conveyed and propelled by the spiral blades 406. In addition, when this device is in use, the discharge pipe 403 can be placed above the external conveyor belt. The propelled shavings fall onto the surface of the external conveyor belt through the discharge pipe 403. After being conveyed by the external conveyor belt, they are sent to the particleboard production machine, where the shavings are combined and made into particleboard board structures. The above-mentioned shaving production and particleboard manufacturing are existing technologies and will not be elaborated on here.

[0060] In the initial state: the drive source (the aforementioned electric motor) of the wood chipper body 2 is electrically connected to the drive motor 404 in the quantitative conveying mechanism, and the drive motor 404 is set as a geared motor, and its running speed is sufficient to fill the gaps generated by the pitch of the spiral blades 406 by the falling wood chips. At the same time as the wood chipper body 2 starts to run and chip the wood, the drive motor 404 starts to decelerate and transport the produced wood chips. It should also be noted that the feed pipe 402 is set to a short distance and serves as the feed inlet of the wood chip conveying cylinder 401, allowing the wood chips to fall from the outer shell of the wood chipper body 2 into the wood chip conveying cylinder 401.

[0061] The following is the working process of the quantitative conveying mechanism for quantitatively conveying the wood shavings produced by the wood shaving machine body 2:

[0062] As the wood shavings fall through the feed pipe 402 into the wood shaving conveyor cylinder 401, driven by the drive motor 404, the rotating shaft 405, rotatably connected inside the wood shaving conveyor cylinder 401, simultaneously begins to rotate. Figure 3As shown, since the spiral blades 406 are fixed on the outer surface of the rotating shaft 405, the spiral blades 406 rotate synchronously when the rotating shaft 405 rotates, conveying the wood shavings that fall into the wood shaving conveying cylinder 401. Since the pitch of the spiral blades 406 is the same, as the drive motor 404 decelerates, the falling wood shavings can be conveyed in equal amounts, thereby ensuring that the wood shavings are evenly distributed during transportation. This avoids the phenomenon of excessive wood shavings accumulation in some areas and insufficient wood shavings supply in other areas. In other words, the amount of wood shavings used can be effectively controlled when feeding the wood shavings, so that the amount of wood shavings used in the subsequent particleboard production process is consistent, thereby improving the production efficiency of wood shavings, reducing the production time and cost caused by uneven wood shavings supply, and ensuring that the raw material quality of each particleboard is consistent, avoiding the situation where the product quality fluctuates and becomes unstable due to insufficient or excessive wood shavings.

[0063] It should also be noted that the flow rate of wood shavings can be controlled by adjusting the running speed of the drive motor 404, so that the flow rate of wood shavings is matched with the amount of particleboard required for production.

[0064] Please refer to the above work process. Figures 1 to 3 .

[0065] The following describes the working process of the outer wall striking mechanism reciprocatingly striking the outer walls of the material transfer pipe 402 and the discharge pipe 403:

[0066] While the drive motor 404 drives the rotating shaft 405 to rotate on the wood shavings conveying cylinder 401, the end of the rotating shaft 405 away from the drive motor 404 passes through the wood shavings conveying cylinder 401 and is fixed with a turntable 408. A lever 409 is mounted off-center on the turntable 408. As the rotating shaft 405 rotates, the turntable 408, in coordination with the lever 409, rotates synchronously around the shaft 405 as its axis at the end of the wood shavings conveying cylinder 401. Figure 5 As shown, since the first linkage frame 501 in the outer wall tapping mechanism is slidably connected to the lever 409, when the lever 409 rotates, it can drive the first linkage frame 501 to move laterally back and forth between the two first limit frames 507. At this time, the Z-shaped toothed plates 502 symmetrically arranged on both sides of the first linkage frame 501 will also move back and forth synchronously, driving the gears 506 that mesh with them to rotate. It should be noted that each Z-shaped toothed plate 502 is matched with a gear 506, and since the movement trajectory of the Z-shaped toothed plate 502 is a left and right lateral back and forth movement, only one side of the gear 506 will be driven to rotate at the same time. When the Z-shaped toothed plate 502 loses contact with the gear 506, the other gear 506 will start to rotate. Therefore, as the Z-shaped toothed plate 502 moves, the gears 506 on both sides can be driven to rotate in sequence and rotate synchronously back and forth with the Z-shaped toothed plate 502.

[0067] Furthermore, while the Z-shaped toothed plate 502 drives the gear 506 to rotate, as... Figure 1 , Figure 3 as well as Figure 5 As shown, since the gear 506 is coaxially mounted with the torsion spring shaft 504, and both ends of the torsion spring shaft 504 are mounted with striking plates 505, and the striking plates 505 are symmetrically arranged on both sides of the feed pipe 402 and the discharge pipe 403, when the gear 506 drives the torsion spring shaft 504 to rotate, the striking plates 505 on it rotate synchronously with the torsion spring shaft 504 as the center, and strike the outer walls of the feed pipe 402 and the discharge pipe 403 to promote the downward movement of the wood shavings, so that the falling wood shavings can be more loose, thereby reducing the generation of wood shavings clumping.

[0068] Please refer to the above work process. Figures 1 to 5 .

[0069] The following describes the working process of the inner wall scraping mechanism reciprocatingly scraping the inner wall of the feed pipe 403:

[0070] It should be noted that, as Figure 4 As shown, the first linkage frame 501 is a vertical rod, and the second linkage frame 601 is a horizontal rod. Both the first linkage frame 501 and the second linkage frame 601 slide on the outside of the lever 409. Under the action of the rotation of the lever 409, the first linkage frame 501 moves horizontally left and right, and the second linkage frame 601 moves vertically up and down. It should also be noted that the cleaning ring 608 is in contact with the inner ring wall of the feed tube 403.

[0071] As the lever 409 rotates with the turntable 408 and drives the first linkage frame 501 to move horizontally and reciprocally, such as Figure 6 As shown, since a second linkage frame 601 is slidably connected to the outer surface of the lever 409, the second linkage frame 601 will also move synchronously under the rotation of the lever 409. Since the second linkage frame 601 is a horizontal bar, it can reciprocate vertically up and down between the second limit frame 602. Figure 6 and Figure 7As shown, because the cleaning ring 608 is slidably connected to the inner wall of the feed pipe 403, and the cleaning ring 608 is connected to the slide rod 604 through the connecting frame 607, and the pressure plate 603 installed on the top of the slide rod 604 is initially subjected to the elastic force of the return spring 605, which lifts the pressure plate 603 to adhere to the bottom surface of the second linkage frame 601. At this time, the pressure plate 603 is away from the positioning plate 606, and the cleaning ring 608 is also on the inner wall of the end of the feed pipe 403 facing the shavings conveying cylinder 401. When the second linkage frame 601 moves downward under the rotation of the lever 409, it will resist the pressure plate 603 and move downward synchronously. Because the slide rod 604 slides through the positioning plate 606, the slide rod 604 slides downward synchronously with the downward movement of the pressure plate 603. At this time, the return spring 605 is compressed.

[0072] The cleaning ring 608 will slide downward on the inner wall of the feeding pipe 403 in sync with the movement of the connecting frame 607, so that the cleaning ring 608 gradually moves away from the shavings conveying cylinder 401. When the second linkage frame 601 moves upward, the resistance of the pressure plate 603 gradually decreases. Under the elastic force of the return spring 605, it will not only drive the pressure plate 603 to rise, but also cause the slide rod 604 to slide in the opposite direction on the positioning plate 606, thereby driving the downward-moving cleaning ring 608 to move upward and return to the initial position. This achieves reciprocating scraping and cleaning of the inner wall of the feeding pipe 403, reducing the shavings residue on the inner wall of the feeding pipe 403, and ensuring that the shavings flow rate is consistent each time, thereby improving the stability of the subsequent production quality of particleboard.

[0073] Please refer to the above work process. Figures 1 to 7 .
