Description

Technical Field

[0001] This utility model relates to the technical field of particleboard production equipment, specifically a high-precision thickness control device for particleboard laying section. Background Technology

[0002] In the particleboard production process, the laying stage is a crucial step that determines the uniformity of board thickness and quality. Traditional thickness control during laying mainly relies on manual adjustment or simple testing devices, which suffers from problems such as low thickness detection accuracy, delayed adjustment, and insufficient flatness. Because the particleboard is not effectively vibrated and leveled after laying, it is prone to resulting in a loose internal structure and uneven density in the board, affecting the mechanical properties and surface quality of the final product.

[0003] In addition, the existing technology lacks a real-time detection and feedback mechanism for paving thickness, making it difficult to achieve high-precision dynamic adjustment, resulting in low production efficiency and a high scrap rate.

[0004] Therefore, there is a need for a high-precision control device that can detect, automatically adjust, and ensure uniformity of paving thickness in real time. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision thickness control device for particleboard paving, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-precision thickness control device for a particleboard laying section, wherein the laying section is equipped with a conveyor belt for cyclic operation, the conveyor belt including a frame and a conveyor belt; characterized in that: the control device is fixedly mounted on the frame, the control device including a vibration component and a detection device, the vibration component being fixedly mounted in the frame and in contact with the conveyor belt, the detection device including a first detection component and a second detection component being disposed opposite to each other on the frame at a certain distance along the direction of operation of the conveyor belt; the first detection component including a first gantry frame fixedly mounted on both sides of the frame and a first thickness detector vertically mounted on the first gantry frame, the second detection component including a second gantry frame fixedly mounted on both sides of the frame and a second thickness detector slidably mounted on the second gantry frame via a slide, wherein the laid particleboard moves with the conveyor belt and sequentially passes through the first thickness detector to measure the thickness, the vibration component vibrates and flattens the laid particleboard, and the second thickness detector measures the final high-precision thickness.

[0008] Furthermore, the vibration assembly includes four supports fixedly installed on the two inner side walls of the frame, and a cradle fixedly connected to the four supports by compression springs. The cradle is equipped with a vibrator and is connected to the conveyor belt by a contact connection kit.

[0009] Furthermore, the contact connection kit includes a wheel assembly formed on the top of the cradle and a groove formed on the inner top surface of the conveyor belt. The wheel assembly is slidably installed in the groove to maintain contact between the vibration assembly and the inner top surface of the conveyor belt, so that the vibrator can drive the conveyor belt to vibrate.

[0010] Furthermore, vertical grooves are formed on the inner walls of both sides of the second gantry frame, and the two ends of the slide are slidably connected to the vertical grooves. A second thickness detector is installed on the bottom surface of the slide, and a rotating seat is formed on the top surface of the slide. The rotating seat is rotatably connected to an adjusting shaft with a threaded hole on its top surface. A screw is fixedly formed on the inner top surface of the second gantry frame, and the screw is threadedly connected to the adjusting shaft.

[0011] Furthermore, the adjusting shaft includes a stepped shaft and a regular hexagonal prism coaxially connected to each other, the stepped shaft is rotatably connected to the rotating base, and the threaded hole is formed on the top surface of the regular hexagonal prism.

[0012] Furthermore, both the first thickness detector and the second thickness detector are laser rangefinders.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention achieves two-stage detection of the paving thickness through the combined use of a first detection component and a second detection component. The first thickness detector measures the initial paving thickness, the vibration component vibrates and flattens the wood shavings, and the second thickness detector performs a high-precision measurement of the final thickness, forming a closed-loop control to ensure thickness uniformity. The vibration component, through the cooperation of a cradle and a vibrator, dynamically vibrates the shavings after paving, effectively eliminating internal voids, improving the density and surface flatness of the board, and providing stable detection conditions for the second thickness detector.

[0015] In addition, the second thickness detector can achieve precise vertical position adjustment through the cooperation of the slide and the adjusting shaft, adapting to the production needs of particleboard of different thicknesses, further improving the flexibility and applicability of the device; the vibration component adopts a cradle design supported by compression springs, which can effectively transmit vibration and reduce the impact on the conveyor belt and frame, extending the service life of the equipment.

Detailed Implementation

[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a high-precision thickness control device for particleboard laying section, which is used to vibrate the laid particleboard to solve the problems of loose internal structure and uneven density of the board, so as to improve the mechanical properties and quality of the final product.

[0024] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the high-precision thickness control device includes a conveyor belt machine 1, which consists of a frame 2 and a conveyor belt 3. The conveyor belt 3 has partition strips 27 on both sides of its surface. The previous process requires continuously laying wood shavings onto the conveyor belt 3 to form a laid wood shaving board 26. The two partition strips 27 act as laying molds. The wood shaving laying process is an existing mature process.

[0025] Furthermore, the control device is fixed on the frame 2 and includes a vibration assembly 4 and a detection device 5. The detection device 5 further includes a first detection assembly 6 and a second detection assembly 7 spaced apart along the conveying direction. The vibration assembly 4 is disposed within the frame 2 and located between the first detection assembly 6 and the second detection assembly 7. The first detection assembly 6 is fixed to both sides of the frame 2 via a first gantry 8, and a first thickness detector 9 is vertically mounted on the first gantry 8 for measuring the initial paving thickness. The second detection assembly 7 is fixed to both sides of the frame 2 via a second gantry 10, and a second thickness detector 12 is slidably mounted on the second gantry 10 via a slide 11 for measuring the final thickness after vibration leveling.

[0026] Further optimizations, such as Figure 1 and Figure 3 As shown, the vibration assembly 4 includes four support bodies 13, which are fixedly installed on the two inner side walls of the frame 2. A cradle 15 is connected to the support bodies 13 via compression springs 14, and the vibrator 16 is installed in the cradle 15. A wheel set 18 is provided at the top of the cradle 15, and a groove 19 is formed on the inner top surface of the conveyor belt 3. The wheel set 18 is slidably installed in the groove 19, allowing the vibration of the vibrator 16 to be transmitted to the conveyor belt 3 through the cradle 15, thus achieving vibration and smoothing of the wood shavings.

[0027] Preferred, such as Figure 3 and Figure 5 As shown, vertical grooves 20 are formed on the inner walls of both sides of the second gantry frame 10, and the two ends of the slide 11 are slidably connected in the vertical grooves 20. A rotating seat 21 is provided on the top surface of the slide 11, and the adjusting shaft 22 is rotatably connected to the rotating seat 21 through a stepped shaft 24. The regular hexagonal prism 25 at the top of the adjusting shaft 22 is provided with a threaded hole, which is threadedly connected to the screw 23 on the inner top surface of the second gantry frame 10. By rotating the adjusting shaft 22, the slide 11 can be driven to move along the vertical grooves 20, thereby adjusting the height of the second thickness detector 12 to adapt to the detection requirements of different thicknesses. Appropriately adjusting the height of the second thickness detector 12 is beneficial to improving the detection accuracy (generally, the detection accuracy will be lower the farther the detector is from the detection target).

[0028] Specifically, both the first thickness detector 9 and the second thickness detector 12 are laser rangefinders, which are non-contact and highly accurate, and can provide real-time feedback of thickness data.

[0029] When using this device, the laid wood shavings move with the conveyor belt 3, first passing through the first thickness detector 9 to measure the initial thickness, and then entering the area of ​​the vibration assembly 4. The vibrator 16 drives the rocker arm 15 to vibrate, and through the cooperation of the wheel set 18 and the slide 19, the vibration is transmitted to the conveyor belt 3 to vibrate and flatten the wood shavings. The flattened wood shavings continue to move to the area of ​​the second detection assembly 7, where the second thickness detector 12 measures the final thickness. If the thickness does not meet the requirements, dynamic control can be achieved by adjusting the parameters of the vibration assembly 4 (such as adjusting the vibration frequency of the vibrator 16).

[0030] This invention achieves high-precision control of particleboard thickness through the combined use of a first detection component, a vibration component, and a second detection component, significantly improving the uniformity and quality of the board while reducing the scrap rate and increasing production efficiency.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
