Description

Technical Field

[0001] This utility model relates to a fiberboard fiber bin material discharging and dispersing device, belonging to the field of board processing technology. Background Technology

[0002] Currently, in MDF production lines, the physical properties of finished boards are closely related to their density, and a good density distribution is a guarantee of quality. The density distribution in the laying line directly determines the density distribution of the finished boards. The main laying method is roller laying, where fibers stored in the fiber silo are conveyed to the feed roller via a belt conveyor. The feed roller breaks up the fibers, allowing them to fall freely onto the roller laying machine, thus achieving the laying purpose.

[0003] However, in actual production and use, especially when making thick boards, the amount of fiber laid on the sides is significantly less than that in the middle, resulting in uneven density and thickness of the finished boards.

[0004] After searching the existing technology, Chinese patent CN211164447U was found to disclose a transverse density adjustment device for fiberboard blank laying. The device includes a processing platform with a feeding hopper at its upper end, a sliding track above the platform, a sliding seat within the track, and a leveling roller at the lower end of the sliding seat. Several adjusting plates are pivotally connected to the upper end of the processing platform. A horizontal pressure plate is located at the right end of each adjusting plate, and a waste hopper is located below the horizontal pressure plate. Weight sensors are mounted on the adjusting plates, and adjusting piston rods are connected to the lower ends of the adjusting plates. A PLC controller connects the weight sensors and the adjusting piston rods to ensure flattening of the end faces. By adjusting the lifting and lowering of the bottom adjusting plate, the amount of fiber entering the horizontal pressure plate position is made uniform. Each module can be raised and lowered independently, achieving precise adjustment of the local fiber amount. The fiber amount on both sides of the board can be easily adjusted to be the same during laying. While this patent uses a leveling roller to adjust the fiber amount on both sides, in practical applications, it was found that the height of the leveling roller is fixed and cannot be adjusted when producing boards of different thicknesses, affecting usability. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a fiberboard fiber bin material dispensing and dispersing device, which can effectively solve the problem of uneven fiber laying on both sides and the middle area of ​​the board, and ensure that the density and thickness of the finished board are uniform.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A fiberboard fiber bin feeding and dispersing device, comprising:

[0008] The frame is provided with a feeding port;

[0009] Multiple drive mechanisms are mounted on the frame;

[0010] Multiple connecting shafts are rotatably mounted on the frame across the feed port, and one end of each connecting shaft is connected to a corresponding drive mechanism.

[0011] Multiple angle detection mechanisms are mounted on the frame. Each angle detection mechanism has a detection end, which is connected to the other end of the corresponding connecting shaft.

[0012] Multiple adjusting plates, wherein the adjusting plates are fixedly mounted on the corresponding connecting shafts;

[0013] The adjusting plate rotates as the connecting shaft rotates.

[0014] Furthermore, a specific type of drive mechanism is provided, wherein the drive mechanism is a continuously variable speed motor.

[0015] Furthermore, a specific type of drive mechanism is provided, which is a servo motor or a stepper motor.

[0016] Furthermore, the specific number of adjustment plates is provided, which is five.

[0017] Furthermore, the number of the driving mechanisms is five, and each driving mechanism corresponds to one of the adjustment plates.

[0018] Furthermore, the cross-sectional shape of the adjustment plate is a rhombus, which is larger in the middle and smaller at both ends.

[0019] Furthermore, the angle detection mechanism is an angle sensor.

[0020] Furthermore, the multiple connecting shafts are arranged in parallel.

[0021] This invention precisely adjusts the fiber flow direction through independent angle control of the adjustment plate, solving the problems of central accumulation and insufficient fiber on both sides; the drive mechanism adopts a stepless speed-regulating motor or servo motor to achieve flexible angle control; the diamond-shaped cross-section adjustment plate optimizes the fiber dispersion effect and avoids accumulation; multiple parallel adjustment plates cover the full width of the feed port, adapting to the production of different specifications of boards.

[0022] By adopting the above technical solution, this utility model has the following beneficial effects:

[0023] In this invention, during use, fibers fall into the feed port of the frame through the feed port. The adjusting plate rotates under the drive mechanism, changing the direction and distribution of the fibers. The angle detection mechanism displays the angle information of the adjusting plate. By rotating the adjusting plate, the direction of the fibers during the feeding process is guided, achieving uniform fiber distribution.

[0024] In addition, the drive mechanism adopts a stepless speed-regulating motor, which makes the rotation angle control of the adjustment plate more flexible and precise; the parallel arrangement of multiple connecting shafts, combined with the coordinated work of multiple adjustment plates, can realize the decentralized adjustment of the entire feeding port, effectively adapting to the laying requirements of slabs of different specifications and thicknesses; at the same time, the cross-section of the adjustment plate is designed as a diamond structure with a larger middle and smaller ends, which is more conducive to dispersing and guiding the fiber flow to both sides and preventing the fiber from accumulating in the middle.

[0025] In summary, this utility model effectively solves the problem of fiber concentration in the middle and insufficient fiber distribution on both sides, improves the uniformity of fiber distribution, and thus significantly improves the density uniformity and overall physical properties of the finished board.

[0029] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0030] like Figure 1-2 As shown, a fiberboard fiber bin feeding and dispersing device includes:

[0031] Frame 1, with a feeding port on it;

[0032] Five drive mechanisms 2 are mounted on the frame 1;

[0033] Five connecting shafts 3 are mounted on the frame 1, spanning the feed inlet. One end of the connecting shaft 3 is connected to the corresponding drive mechanism 2.

[0034] Five angle detection mechanisms 4 are installed on the frame 1. Each angle detection mechanism 4 has a detection end, which is connected to the other end of the corresponding connecting shaft 3.

[0035] Five adjusting plates 5 are fixedly mounted on the corresponding connecting shafts 3;

[0036] The adjusting plate 5 rotates along with the rotating shaft 3.

[0037] In this embodiment, as Figure 1-2 As shown, the specific operating process of this fiberboard fiber bin material discharging and dispersing device is as follows:

[0038] First, the operator starts the equipment, and the five drive mechanisms 2 begin to work, driving the five connecting shafts 3 connected to them to rotate, which in turn drives the five adjusting plates 5 fixed on the connecting shafts 3 to rotate to their initial angle positions. The five angle detection mechanisms 4 monitor the angle of each connecting shaft 3 in real time. This embodiment also includes a controller, which is electrically connected to the drive mechanism 2 and the angle detection mechanism 4, and is used to receive the angle data from the angle detection mechanism 4 and control the working state of the drive mechanism 2.

[0039] During production, fibers fall from above the fiber silo through the feed port, passing sequentially through five adjusting plates 5 arranged parallel to each other along the width of the frame 1. Depending on actual production needs, the fibers are guided to different positions along the surface of the adjusting plates 5, thereby altering the fiber distribution. For example, if the amount of fiber on both sides of the laying line is less than in the middle, the angle of the adjusting plates 5 on both sides can be adjusted to guide more fibers to both sides of the laying line, thus achieving uniform fiber distribution.

[0040] In addition, it can be used in conjunction with the thickness measuring instrument of the paving machine. Specifically, the thickness measuring instrument monitors the fiber thickness at different locations on the paving line. When insufficient fiber thickness is detected at certain locations, the operator can manually adjust the angle of the corresponding adjustment plate 5 based on the measurement results, guiding more fibers to the insufficient thickness location, thereby adjusting the fiber distribution and ensuring the uniformity of the density and thickness of the finished board. Throughout the process, five angle detection mechanisms 4 continuously provide angle feedback information to ensure that the angle adjustment of the adjustment plate 5 is accurate and controllable.

[0041] In this embodiment, the adjusting plate 5 and the connecting shaft 3 are welded together as a whole.

[0042] Specifically, such as Figure 1 As shown, drive mechanism 2 is a continuously variable speed motor.

[0043] Specifically, such as Figure 1-2As shown, there are five adjustment plates 5 and five drive mechanisms 2, with each drive mechanism 2 corresponding to one adjustment plate 5.

[0044] Specifically, such as Figure 1-2 As shown, the cross-sectional shape of the adjustment plate 5 is a rhombus, which is larger in the middle and smaller at both ends.

[0045] Specifically, such as Figure 1 As shown, the angle detection mechanism 4 is an angle sensor.

[0046] In this embodiment, as Figure 1-2 As shown, fibers fall from above the feed inlet and are dispersed and guided by adjusting plates 5. Each adjusting plate 5 is connected to a corresponding drive mechanism 2 via a connecting shaft 3. The drive mechanism 2 can be a continuously variable speed motor or other devices capable of outputting rotation, such as a servo motor, stepper motor, hydraulic motor, or a combination of one of these with a reducer. The drive mechanism 2 controls the rotation angle of the adjusting plate 5, thereby changing the fiber distribution.

[0047] The cross-sectional shape of the adjusting plate 5 is a rhombus, which is larger in the middle and smaller at both ends. This makes it less likely for fibers to accumulate on the adjusting plate 5 during the falling process, and can guide the fibers to different positions according to the angle of the adjusting plate 5.

[0048] In some embodiments, the number of adjusting plates 5 is not limited to five and can be set according to specific needs. Similarly, the number of drive mechanisms 2 can also be adjusted accordingly based on the number of adjusting plates 5. Multiple connecting shafts 3 are arranged in parallel, and each connecting shaft 3 is fixed with an adjusting plate 5. This structure allows each adjusting plate 5 to be controlled independently, thereby adjusting the fiber distribution density at different positions according to the needs of fiberboard production, making the density distribution of the finished board more uniform.

[0049] Specifically, such as Figure 1-2 As shown, the five connecting shafts 3 are arranged in parallel.

[0050] In this embodiment, as Figure 1-2 As shown, five connecting shafts 3 are arranged in parallel on the frame 1, and an adjusting plate 5 is fixed on each connecting shaft 3. The two ends of the shaft 3 are connected to the drive mechanism 2 and the angle detection mechanism 4, respectively. The parallel arrangement ensures that the adjusting plates 5 maintain an appropriate distance from each other, avoiding mutual interference, while covering the entire width of the feed inlet. When the fibers fall from the feed inlet, they are dispersed and guided by these parallel adjusting plates 5, enabling precise control of the fiber distribution across the entire paving width.

[0051] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
