Description

Technical Field

[0001] This invention relates to the field of hot pressing technology, specifically to a double-beam hot press and hot pressing system for equal thickness pressing. Background Technology

[0002] Sheet metals are flat, rectangular building materials made to standard sizes and used in the construction industry as components for walls, ceilings, or floors. Based on thickness, sheet metals are classified into thin sheets, medium sheets, thick sheets, and extra-thick sheets.

[0003] The current board production process is as follows: After the raw materials such as the face and base boards, frames, keels, magnesium oxide boards, and honeycomb boards are glued and assembled manually, they are stacked neatly at a certain height. Then, a weight that is compatible with the board size is placed on top of each stack to press the stack into shape.

[0004] The existing board production process has the following problems: 1. Stacking and pressing are all done manually, resulting in low production efficiency, high labor intensity, and low product yield and poor product consistency. 2. The cold pressing process requires a long pressing time to ensure the adhesive cures and forms the desired shape. The pressing time is 2-3 hours in summer and 3-4 hours in winter. In the low-temperature conditions of northern regions, even longer pressing times are required, which seriously affects the product production cycle and results in very low production efficiency. In addition, the above-mentioned heavy object pressing method also has the following problems: First, the surface quality of the heavy object is poor, and its direct contact with the raw materials will lead to poor surface quality of the product. Second, during the pressing process relying on gravity, the heavy object cannot guarantee that the applied pressing force is evenly distributed within the width, which will lead to uneven thickness of the product, i.e., large thickness deviation. Third, the pressing force of the heavy object is its weight, and the magnitude of the pressing force cannot be adjusted. The pressure cannot be adjusted according to the width of the product, making it difficult to guarantee the bonding quality of the product. Summary of the Invention

[0005] The purpose of this invention is to provide a double-beam hot press and hot pressing system for equal thickness pressing, so as to solve the above-mentioned problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a double-beam hot press for equal thickness pressing, comprising a support frame, a hot pressing unit, a drive unit, and a control unit. At least one hot pressing unit is mounted on the support frame, and the drive unit has at least one output group. The hot pressing units are connected to and correspond one-to-one with the output groups. Each output group has several drivers. Each hot pressing unit includes an upper crossbeam and a lower crossbeam arranged opposite each other. An upper hot pressing plate is provided on the bottom surface of the upper crossbeam, and a lower hot pressing plate is provided on the top surface of the lower crossbeam. A first heat insulation layer is provided between the upper hot pressing plate and the upper crossbeam. A second heat insulation layer is provided between the hot press plate and the lower crossbeam. Both the first and second heat insulation layers are heat-equalizing heat insulation layers. The heat-equalizing heat insulation layer includes a number of spaced-apart support strips, and heat insulation space is formed between adjacent support strips. The driver is connected to the upper or lower crossbeam. The driver is equally spaced on the sides of the upper and lower crossbeams and is used to drive and guide the movement of the hot press unit. A conveying mechanism for material movement is provided on the lower crossbeam. The control unit is communicatively connected to the drive unit and the conveying mechanism.

[0007] Furthermore, a thickness-fixing device is provided between the upper crossbeam and the lower crossbeam, the thickness-fixing device being used to ensure that the distance between the upper hot press plate and the lower hot press plate is equal.

[0008] Furthermore, the upper hot plate and the lower hot plate are thin hot plates, with a length greater than 4 meters and a thickness of 20-50 millimeters.

[0009] Furthermore, when there are multiple hot-pressing units, adjacent hot-pressing units are arranged vertically at intervals, or adjacent hot-pressing units are arranged horizontally at intervals.

[0010] Furthermore, the actuator is a hydraulic cylinder, a lifting mechanism, or an electric cylinder.

[0011] Furthermore, the control unit includes a control module, a communication module, and a temperature control module. The control module is communicatively connected to the drive unit, the transmission mechanism, and the temperature control module through the communication module. The temperature control module is disposed on the upper hot platen and the lower hot platen and is used to control the temperature of the upper hot platen and the lower hot platen.

[0012] Furthermore, the parts of the upper hot press plate, the lower hot press plate, and the conveying mechanism that come into contact with the material are all provided with a friction-reducing layer.

[0013] The present invention also provides a hot pressing processing system, including the aforementioned double-beam hot press for equal thickness pressing. The hot press has a feeding mechanism and a discharging mechanism on both sides, and the hot press is located between the feeding mechanism and the discharging mechanism. When the hot press has multiple hot pressing units, the feeding mechanism and the discharging mechanism are respectively provided with a material transfer module, which is used to transport materials to different hot pressing units.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are as follows: The present invention relates to a double-beam hot press and hot pressing system for equal thickness pressing. The hot press plate provides heat to heat and press the sheet material, allowing the adhesive to quickly reach its curing temperature, effectively shortening the curing time. Compared to the existing cold pressing process which requires 3-6 hours of pressing time, the pressing time can be reduced to 1.5-10 minutes, significantly improving production efficiency. Simultaneously, the use of a double-beam structure as an independent load-bearing component allows for reinforced design to meet load-bearing requirements, improving overall rigidity and resisting deformation during pressing. The output ends of the drive units are evenly distributed on the hot press unit, and the drivers are evenly spaced on the sides of the upper and lower beams, ensuring uniform distribution of pressing force within the width. A thickness-fixing device is provided between the upper and lower beams, ensuring equal spacing between the upper and lower hot press plates, thereby guaranteeing consistent thickness of the product throughout the width and effectively solving the problem of large thickness deviations in existing technologies.

[0015] Furthermore, this invention provides uniform heat insulation layers between the upper hot press plate and the upper crossbeam, and between the lower hot press plate and the lower crossbeam. These uniform heat insulation layers include several spaced-apart support strips, forming an insulation space between adjacent support strips. The support strips reduce the contact area between the hot press plate and the crossbeam to reduce heat conduction. The insulation space reduces heat conduction efficiency through thermal convection, concentrating heat on the product. Simultaneously, the two ends of the insulation space are connected to the outside, allowing air to flow along the insulation space, forming a hot airflow that makes the crossbeam heat more evenly heated. This effectively solves the problem of uneven thermal deformation caused by uneven heating of the crossbeam, ensuring the hot pressing accuracy during long-term use. The control unit communicates with the drive unit and the conveying mechanism to achieve closed-loop control of parameters such as time, temperature, and pressure, automatically executing actions such as feeding, closing, pressurizing, holding, opening, and discharging. By setting feeding and discharging mechanisms on both sides of the hot press, a complete hot pressing processing system is formed, automating feeding, pressing, and discharging, further reducing the labor intensity of manual operations.

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] In the description of this invention, it should be understood that the terms "length," "width," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1 like Figure 1 , Figure 2 As shown, the double-beam hot press for equal thickness pressing in this embodiment 1 includes a support 1, a hot pressing unit 2, a drive unit 3, and a control unit. The hot pressing unit 2 is provided with at least one and is respectively arranged on the support 1. The drive unit 3 is provided with at least one output group. The hot pressing unit 2 is connected to the output group and is arranged in a one-to-one correspondence. Each output group has several output ends, and the output ends are evenly distributed on the hot pressing unit 2.

[0024] The hot pressing unit 2 includes an upper crossbeam 21 and a lower crossbeam 22 arranged opposite to each other. At least one of the bottom surface of the upper crossbeam 21 and the top surface of the lower crossbeam 22 is provided with a hot pressing plate 4. The lower crossbeam 22 is provided with a conveying mechanism 5 for material movement. Correspondingly, the output end is connected to the upper crossbeam 21 or the lower crossbeam 22. The control unit is communicatively connected to the drive unit 3 and the conveying mechanism 5.

[0025] Specifically, the support 1 can be constructed in any suitable structure to adapt to different production conditions. In the hot pressing unit 2, the upper crossbeam 21 and the lower crossbeam 22, which are arranged opposite each other, form a double-beam structure. This structure is simple, reliable, and easy to maintain. The hot pressing plate 4 is used to directly contact the raw materials. The high temperature of the hot pressing plate 4 allows the adhesive to quickly reach its curing temperature, effectively shortening the curing time. Furthermore, the fluid properties of the adhesive are better after preheating by the hot pressing plate 4, which helps to expand the contact area between the adhesive and the raw materials, thereby improving the bonding strength. For the parts of the hot pressing unit 2 that directly contact the raw materials, namely the hot pressing plate 4, the upper crossbeam 21, or the lower crossbeam 22, high-precision processing is performed to improve their surface quality, which indirectly improves the surface quality of the product.

[0026] Meanwhile, the conveying mechanism 5 enables the movement of raw materials and finished products within the hot press, eliminating the need for manual dragging and reducing the labor intensity of manual operations. Furthermore, the number of hot pressing units 2 can be increased or decreased according to user needs, with single or multiple units in arbitrary combinations, offering flexibility, convenience, and practicality. Moreover, the hot press does not require digging a foundation pit during installation, saving users investment in foundation construction.

[0027] In this embodiment, the drive unit 3 provides pressing force to press the raw material into a product. The pressing force provided by the drive unit 3 can be effectively adjusted, so the hot pressing time and pressure are adjustable and controllable, resulting in better controllability of the pressing and helping to improve the quality of the product. Furthermore, the output ends of the drive unit 3 are evenly distributed on the hot pressing unit 2, so that the upper crossbeam 21 or the lower crossbeam 22 presses down evenly, and the pressing force is evenly distributed within the width, reducing the thickness deviation of the product.

[0028] The control unit is used to control the operation of the hot press, thereby improving the intelligence and automation of the hot press, realizing automated pressing, and effectively reducing the labor intensity of manual operation.

[0029] During operation, the raw material is placed on the hot pressing unit 2. The conveying mechanism 5 is activated to move the raw material along the hot pressing unit 2, ensuring its even distribution within the pressing area. The drive unit 3 is activated to move either the upper crossbeam 21 or the lower crossbeam 22 towards the other. The drive unit 3 provides pressing force while also acting as a guide, and the pressing force is precisely adjusted according to process requirements. The hot pressing plate 4 provides appropriate heat, causing the adhesive within the raw material to solidify and form, shortening the product molding time and improving production efficiency. After molding, the drive unit 3 drives the upper crossbeam 21 or the lower crossbeam 22 to reset, and the conveying mechanism 5 is activated again to push the product out, while simultaneously pulling in the raw material for the next pressing operation.

[0030] Preferably, a guide mechanism can be provided on the basis of the drive unit 3 to guide the movement of the upper crossbeam 21 or the lower crossbeam 22, thereby improving the accuracy of the movement. Furthermore, any suitable commercially available model can be selected as the guide mechanism.

[0031] For the conveying mechanism 5, any suitable commercially available model can be selected, offering a wide range of choices and good practicality. Correspondingly, the parts of the upper crossbeam 21, lower crossbeam 22, hot press plate 4, and conveying mechanism 5 that come into contact with the raw materials are all provided with a friction-reducing layer. The friction-reducing layer is made through friction-reducing measures such as air flotation, oil flotation, magnetic flotation, or coating with a friction-reducing coating, in order to reduce the coefficient of friction and reduce the driving force required for the movement of the raw materials.

[0032] Optionally, the support frame 1 consists of several columns, which are divided into two opposing support groups, with the columns in each support group being spaced at equal intervals.

[0033] In this embodiment, the hot press plate 4 includes an upper hot press plate 41 fixed to the bottom surface of the upper crossbeam 21 and a lower hot press plate 42 fixed to the top surface of the lower crossbeam 22. A first heat insulation layer 61 is provided between the upper hot press plate 41 and the upper crossbeam 21, and a second heat insulation layer 62 is provided between the lower hot press plate 42 and the lower crossbeam 22. Based on the above design, there are two hot press plates 4, namely the upper hot press plate 41 and the lower hot press plate 42. The two hot press plates 4 are used together to increase the heat provided during pressing, which helps to further shorten the pressing time.

[0034] Meanwhile, considering that the heat from the hot press plate 4 will be conducted to the upper crossbeam 21 and the lower crossbeam 22, a first heat insulation layer 61 and a second heat insulation layer 62 are provided to prevent thermal deformation of the upper crossbeam 21 and the lower crossbeam 22 due to high temperature. This not only provides protection and improves the service life of the upper crossbeam 21 and the lower crossbeam 22, but also concentrates the heat on the product, reducing heat loss. Furthermore, the hot press plate 4 operates in a thermal equilibrium state, which also helps to reduce thermal deformation of the hot press plate 4.

[0035] The heat insulation measures used in the prior art are constant temperature insulation layers (including but not limited to wood boards and fiberboards). Taking the upper beam 21 as an example: the constant temperature insulation layer has low thermal conductivity, but it can still transfer heat. Given that the upper beam 21 has a certain thickness, the heat is gradually conducted from the part of the upper beam 21 that contacts the constant temperature insulation layer along the thickness direction of the upper beam 21. The upper beam 21 experiences uneven heating along the thickness direction, which in turn leads to thermal deformation of the upper beam 21.

[0036] Based on this, both the first heat insulation layer 61 and the second heat insulation layer 62 are heat-equalizing heat insulation layers. The heat-equalizing heat insulation layer includes several spaced-apart support strips, and heat insulation space is formed between adjacent support strips. Among them, the support strips reduce the contact area between the hot press plate 4 and the upper crossbeam 21, thus reducing heat transfer by conduction; the heat insulation space conducts heat through heat convection, reducing heat conduction efficiency and concentrating heat on the product; the two ends of the heat insulation space are connected to the outside, so air flows along the heat insulation space and forms a hot air flow. The hot air flow flows along the upper crossbeam 21 and makes the upper crossbeam 21 more evenly heated, effectively solving the problem of thermal deformation of the upper crossbeam 21.

[0037] While ensuring compressive strength, the load-bearing strip can be made of any suitable material. Furthermore, the effect of the heat-dissipating insulation layer on the lower crossbeam 22 is the same as its effect on the upper crossbeam 21, which will not be elaborated further here.

[0038] The design of evenly distributing the output ends of the drive unit 3 within the hot pressing unit 2 helps improve the uniformity of the pressing force distribution within the width. However, due to the existence of errors and wear caused by long-term use, it is not enough to ensure the above uniformity solely through the even distribution design. Therefore, preferably, a thickness fixing device is provided between the upper crossbeam 21 and the lower crossbeam 22, which ensures that the distance between the upper hot pressing plate 41 and the lower hot pressing plate 42 is equal.

[0039] When the drive unit 3 drives one of the upper crossbeam 21 or the lower crossbeam 22 to move towards the other for pressing, the distance between the two is measured by the thickness fixing device to ensure that the distance is equal at all points within the width, thereby ensuring the equal thickness of the product.

[0040] Preferably, the hot press plate 4 is constructed as a thin hot plate, with a length greater than 4 meters and a thickness of 20-50 millimeters. Based on this, while ensuring the structural strength of the hot press plate 4, the amount of heat required for the hot press plate 4 to heat up is reduced, thereby achieving the goal of reducing power consumption.

[0041] Having multiple hot pressing units 2 helps improve production efficiency. The layout of multiple hot pressing units 2 can also be adjusted according to site conditions. When there are multiple hot pressing units 2, adjacent hot pressing units 2 can be arranged vertically spaced apart, or horizontally spaced apart. That is, the hot pressing units 2 can be arranged vertically in a multi-layer structure to improve the space utilization rate in terms of height, or they can be distributed horizontally at the same height, which is suitable for sites with low height; or, when site conditions are complex, the vertical and horizontal arrangements can be combined to improve the flexibility of use. Based on this, users can choose any suitable layout method according to their own conditions.

[0042] Generally, the hot pressing unit 2 is preferably set vertically at intervals. When the workshop area is limited, the workshop height is effectively utilized, which solves the problem of low production efficiency caused by the limited workshop area and improves production efficiency.

[0043] In this embodiment, the driving unit 3 includes a driver. Several drivers are provided on the same hot pressing unit 2. The drivers are used to drive and guide the movement direction of the hot pressing unit 2. The drivers are equally spaced on the sides of the upper crossbeam 21 and the lower crossbeam 22. Drivers on the same side constitute a driving group. Correspondingly, the output group includes two driving groups, and the output end is a driver.

[0044] The actuator, upper crossbeam 21, and lower crossbeam 22 form a closed force system. The pressing force is precisely adjusted according to process requirements to improve pressing quality. The two drive groups are respectively set on the two sides of the upper crossbeam 21 and the lower crossbeam 22. The actuators in the same drive group are equally spaced to achieve multi-point symmetrical arrangement of the actuators and maximize the uniformity of the pressing force.

[0045] The actuator can be selected from different models of equipment, offering a wide range of choices and ease of use. Specifically, in one possible implementation, the actuator can be selected from hydraulic cylinders, lifting mechanisms, and electric cylinders, or the actuator can be selected from any other suitable commercially available equipment.

[0046] Accordingly, the support frame 1 is equipped with a constant pressure hydraulic station connected to the oil cylinder or the lifting platform. Based on this, the constant pressure hydraulic station ensures a constant pressing force, avoiding the problem of decreased pressing quality caused by fluctuations in pressing force.

[0047] In this embodiment, the control unit includes a control module, a communication module, and a temperature control module. The control module is connected to the drive unit 3, the transmission mechanism 5, and the temperature control module through the communication module. The temperature control module is installed on the hot press plate 4 and is used to control the temperature of the hot press plate 4.

[0048] Based on the above design, a web guiding program can be written into the control module. The hot press uses this program to achieve closed-loop control of parameters such as time, temperature, and pressure. If any measured value deviates from the set value, a corresponding prompt or web guiding program will be executed. When all parameters meet the set values, the press will automatically perform actions such as feeding, closing, pressurizing, venting, pressure holding, opening, and discharging, achieving intelligent production. It is easy to understand that any suitable commercially available web guiding program can be selected.

[0049] The temperature control module is used for real-time monitoring and adjustment of the temperature of the hot press plate 4 to ensure that the hot pressing temperature meets the process requirements. Preferably, the temperature control module can synchronously control the temperature of the upper hot press plate 41 and the lower hot press plate 42, or it can achieve asynchronous control to meet the process requirements of different material products, further improving the processing range.

[0050] Example 2 like Figure 3 As shown, the hot pressing processing system of this embodiment 2 includes the double beam hot press with equal thickness pressing. The hot press is provided with a feeding mechanism 7 and a discharging mechanism 8 on both sides. The hot press is located between the feeding mechanism 7 and the discharging mechanism 8. When the hot press is provided with multiple hot pressing units 2, the feeding mechanism 7 and the discharging mechanism 8 are respectively provided with a material transfer module 9. The material transfer module 9 can transport the material to different hot pressing units 2.

[0051] At this time, the feeding mechanism 7 realizes the automatic feeding of raw materials, and the discharging mechanism 8 realizes the automatic discharging of finished products. The cooperation of the feeding mechanism 7, the discharging mechanism 8 and the hot press further improves the degree of automation of processing, reduces the intensity of manual operation, and also helps to improve production efficiency.

[0052] When the hot press is equipped with multiple hot pressing units 2, the material transfer module 9 is used to assist in the transfer of materials. During feeding, the materials can be easily sent to different hot pressing units 2. During discharging, the products can be output through the same discharging mechanism 8. The feeding mechanism 7 and the discharging mechanism 8 provide one-to-many service, which helps to reduce the number of parts in the hot pressing system and reduce production costs.

[0053] Furthermore, when multiple hot pressing units 2 are arranged vertically, the material transfer module 9 can use any suitable commercially available lifting device; when multiple hot pressing units 2 are arranged horizontally, the material transfer module 9 can use any suitable commercially available horizontal moving device.

[0054] In summary, this invention employs a hot-pressing heating method, significantly reducing the pressing time from 3-6 hours in existing cold-pressing processes to 1.5-10 minutes. The coordinated operation of the double-beam independent load-bearing components, the uniformly distributed drive, and the thickness-fixing device ensures even distribution of pressing force and equal spacing between the upper and lower hot-pressing plates, effectively reducing product thickness deviation. The uniformly heated insulation layer utilizes the spaced arrangement of the load-bearing strips and the heat convection effect of the insulation space to ensure uniform heating of the beams, reducing the risk of thermal deformation and ensuring long-term hot-pressing stability. The closed-loop control unit, combined with the linkage of the feeding and discharging mechanisms, achieves full automation of the feeding, pressing, and discharging process, significantly reducing labor intensity. Therefore, this invention effectively solves the technical problems of long pressing time, poor pressing accuracy, easy thermal deformation of equipment, and low automation in existing technologies, and has good prospects for widespread application.

[0055] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
