Description

Technical Field

[0001] This utility model relates to the field of hot pressing production equipment technology, and in particular to a continuous hot pressing and bonding production equipment for wood fiber wall panels. Background Technology

[0002] With the rapid development of the construction industry, people's requirements for the performance of wall materials are increasing. Wood fiber wall panels, due to their advantages such as lightweight, heat insulation, sound insulation, and environmental friendliness, have been widely used in the construction field. Wood fiber wall panels are typically made by mixing wood fiber materials with adhesives and then hot-pressing them together. The hot-pressing process is a crucial step in the production of wood fiber wall panels, directly affecting key performance indicators such as density, strength, surface smoothness, and dimensional stability.

[0003] Traditional hot-pressing equipment for wood fiber wall panels is mostly intermittent hot press, which has several drawbacks. First, intermittent hot presses require frequent loading, pressing, and unloading operations, resulting in long production cycles and low efficiency, making it difficult to meet the demands of large-scale industrial production. Second, during intermittent hot pressing, it's difficult to maintain consistent parameters (such as temperature, pressure, and time) for each pressing cycle, easily leading to unstable product quality and defects such as uneven density distribution, uneven surfaces, and internal delamination. Furthermore, intermittent hot presses typically require large pressing spaces, resulting in large floor space, high energy consumption, and high production costs.

[0004] In recent years, although some companies have attempted to improve the production efficiency and quality of wood fiber wall panels using continuous hot-pressing lamination technology, existing continuous hot-pressing lamination equipment still faces numerous technical challenges. For example, during continuous hot pressing, the uniform transport and positioning of wood fiber materials between the hot-pressing belts is difficult, easily leading to material misalignment and wrinkles, affecting the lamination effect and appearance quality of the wall panels. Simultaneously, the heating system of continuous hot-pressing equipment often suffers from uneven heating, resulting in inconsistent temperature distribution across the hot-pressing belts, which in turn affects the hot-pressing quality of the wall panels. Furthermore, continuous hot-pressing lamination equipment has a complex structural design, high maintenance costs, and difficulty in precisely controlling the hot-pressing pressure during the process, easily causing uneven density in the wall panels, reducing the product's mechanical properties and service life.

[0005] In summary, existing hot-pressing lamination equipment for wood fiber wall panels has significant shortcomings in terms of continuity, uniformity, stability, and production efficiency. There is an urgent need for a new type of continuous hot-pressing lamination equipment to solve the above-mentioned technical problems, improve the production efficiency and product quality of wood fiber wall panels, and meet the needs of the modern construction industry for high-performance wall materials. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned shortcomings by providing a continuous hot-pressing and bonding production equipment for wood fiber wall panels, thereby achieving continuous, uniform, and stable production to ensure production efficiency.

[0007] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a continuous hot-pressing lamination production equipment for wood fiber wall panels, comprising: A conveying unit, which is U-shaped, is used to convey wall panels; A rotating mechanism is located at the center of the conveying unit. The rotating mechanism is equipped with multiple sets of pressing swing arms. The ends of the pressing swing arms are equipped with hot pressing components. The rotating mechanism is used to drive the multiple sets of hot pressing components to alternately and continuously press against the wall panel as the conveying unit conveys. A cleaning unit is disposed in the gap of the conveying unit and located on one side of the rotating mechanism. The cleaning unit is used to clean the bonding surface of the hot pressing assembly.

[0008] Furthermore, the pressing arms are equidistantly distributed at the top of the rotating mechanism; The top of the rotating mechanism is provided with an adjustment mechanism to control the swing of the pressing arm. The adjustment mechanism is used to keep the pressing arm in a lifting posture or a pressing posture.

[0009] Furthermore, a hinge shaft is provided at the end of the pressing swing arm; The hot-pressing assembly includes a connecting layer, a hot-pressing layer, and an elastic mechanism; The elastic mechanism is disposed between the connecting layer and the hot-pressing layer; The top of the connecting layer is provided with a hinge seat that is connected to the hinge shaft; The hot-pressed layer is equipped with a heating unit and a sealing mechanism.

[0010] Furthermore, the cleaning unit includes a support base, a cleaning roller is disposed inside the support base, a drive unit for driving the cleaning roller is disposed on the support base, and a cleaning groove for accommodating the cleaning roller is provided on the support base. The cleaning roller is positioned perpendicular to the center of rotation of the rotating mechanism; The direction of rotation of the cleaning roller is opposite to the direction of rotation of the rotating mechanism.

[0011] Furthermore, the cleaning groove is provided with cleaning teeth that contact the cleaning roller; The rotating mechanism is tilted to scrape off the adhering substances on the surface of the cleaning roller.

[0012] The beneficial effects of this utility model are reflected in: In this utility model, the conveying unit is used to continuously receive and convey wall panels. When the wall panel moves to the hot pressing section, the rotating mechanism, along with the rotation speed of the conveying unit and in cooperation with the pressing swing arm, presses down the hot pressing assembly to the top of the corresponding wall panel. Then, the hot pressing assembly applies pressure and heats the wall panel without stopping the conveying unit, so that the wall panel can achieve continuous processing. Attached Figure Description

[0015] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figure 1-2 This utility model discloses a continuous hot-pressing lamination production equipment for wood fiber wall panels, comprising: The conveying unit 1 is U-shaped and is used to convey wall panels. The conveying unit 1 is a conveyor belt, or other structures that are easy for those skilled in the art to conceive of. Since this technology is a conventional technology in the prior art, it is not described in detail in this application. It should be noted that one end of the conveying unit 1 is the input end and the other end of the conveying unit 1 is the output end. The semi-circular arc end at the center of the U-shaped conveyor belt is the hot pressing part. When the conveying unit 1 conveys the wall panel to the hot pressing part, hot pressing processing is performed at that point. A rotating mechanism 2 is located at the center of the conveying unit 1. The rotating mechanism 2 is provided with multiple sets of pressing swing arms 3. The ends of the pressing swing arms 3 are provided with hot pressing components 4. The rotating mechanism 2 is used to drive multiple sets of hot pressing components 4 to alternately and continuously press against the wall panel as the conveying unit 1 conveys. The cleaning unit 5 is located in the gap of the conveying unit 1 and on one side of the rotating mechanism 2. The cleaning unit 5 is used to clean the bonding surface of the hot pressing assembly 4.

[0017] In use, the conveying unit 1 is used to continuously receive and convey the wall panel. When the wall panel moves to the hot pressing section, the rotating mechanism 2 rotates with the conveying unit 1 and, in cooperation with the pressing arm 3, presses the hot pressing assembly 4 down onto the top of the corresponding wall panel. Then, the hot pressing assembly 4 applies pressure and heats the wall panel without stopping the conveying unit 1, so that the wall panel can achieve continuous processing.

[0018] It is easy to imagine that the pressing arms 3 are equidistantly distributed at the top of the rotating mechanism 2, and preferably, the number of pressing arms 3 is six groups; The top of the rotating mechanism 2 is provided with an adjustment mechanism for controlling the swing of the pressing arm 3. The adjustment mechanism is used to make the pressing arm 3 be in a lifting posture or a pressing posture. It should be noted that the three sets of pressing arms 3 on the side of the rotating mechanism 2 closest to the hot pressing part are in the pressing posture. When the corresponding pressing arm 3 enters the hot pressing part, the adjustment mechanism drives the pressing arm 3 to press down. When the pressing arm 3 leaves the hot pressing part as it rotates, the adjustment mechanism drives the pressing arm 3 to lift up.

[0019] It should be noted that the end of the pressing swing arm 3 is provided with a hinge shaft; The hot-pressing assembly 4 includes a connecting layer 41, a hot-pressing layer 42, and an elastic mechanism 43; The elastic mechanism 43 is disposed between the connecting layer 41 and the hot-pressing layer 42. It should be noted that the elastic mechanism 43 is an elastic structure with adjustable elastic force. In use, it is used to avoid direct hard contact between the hot-pressing layer 42 and the wall panel, and to change the contact to flexible release, thereby avoiding damage to the wall panel and the conveying unit 1. The top of the connecting layer 41 is provided with a hinge seat 44 connected to the hinge shaft. The hinge seat 44 is used to ensure that the connecting layer 41 and the hot-pressed layer 42 can be completely bonded to the wall panel. The hot-pressed layer 42 is provided with a heating unit and a sealing mechanism. The heating unit is existing technology and therefore is not described in detail in this application. The sealing mechanism is a sealing ring structure, which is used to form a sealed cavity around the wall panel when the hot-pressed layer 42 is pressed down.

[0020] In another preferred embodiment, the cleaning unit 5 includes a support base, a cleaning roller 51 is disposed inside the support base, a drive unit 53 for driving the cleaning roller 51 is disposed on the support base, and a cleaning groove 54 for accommodating the cleaning roller 51 is provided on the support base. The cleaning roller 51 is arranged perpendicular to the rotation center of the rotating mechanism 2; The rotation direction of the cleaning roller 51 is opposite to the rotation direction of the rotating mechanism 2.

[0021] With the above structural setup, when the pressing arm 3 is in the lifting posture, at this time, the pressing arm 3 has just separated from the wall panel. In order to facilitate the cleaning of the hot-pressed layer 42 on it for subsequent reuse, a cleaning unit 5 is set up, which can clean the hot-pressed layer 42 when it is in the lifting posture and when it passes over it.

[0022] Finally, the cleaning groove is provided with cleaning teeth 52 that contact the cleaning roller 51; The rotating mechanism 2 is inclined and used to scrape off the surface of the cleaning roller 51. With this structure, the cleaning roller 51 can be cleaned a second time during use, avoiding secondary pollution caused by residues adhering to the cleaning roller 51 during long-term use.

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0025] Additionally, "multiple" refers to two or more.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
