Description

Technical Field

[0001] The present invention relates to the technical field related to floor production equipment, and in particular to a multi-layer composite floor hot pressing forming device. Background Art

[0002] Multi-layer composite flooring is a material widely used in the field of modern architectural decoration. Its unique structural design gives it good stability and durability. It is made of multiple layers of veneer glued together by high-performance adhesives. The texture direction and tree species of each layer of veneer are scientifically matched to form a criss-cross stacked structure. In the production process of multi-layer composite flooring, hot pressing is one of the most important core processes. This process precisely controls the temperature, pressure and time parameters to fully cure the adhesive and ensure that each layer of veneer is tightly bonded. The quality of the hot pressing process not only directly determines the physical indicators of the floor such as density uniformity and surface flatness, but also has a profound impact on the key performance of the floor such as wear resistance and deformation resistance, and thus becomes a decisive factor in ensuring the quality and market competitiveness of the floor. Therefore, there is a special need for a hot pressing device for multi-layer composite flooring.

[0003] The Chinese patent CN213471546U published on June 18, 2021 discloses a multi-layer composite floor hot pressing device. By adjusting the threaded column, the sliding plate is adjusted. By adjusting the sliding plate, the clamping plate can be adjusted. By adjusting the clamping plate, the composite floor on the lower hot pressing plate can be positioned, avoiding the problem of deflection caused by the inability to position. By adjusting the upper hot pressing plate, the upper hot pressing plate can be brought into contact with the composite floor on the lower hot pressing plate, and hot pressing work can be carried out, avoiding the problem that hot pressing work on the composite floor is more difficult. However, the multi-layer composite floor hot pressing device adopts a single The hot pressing surface design concentrates the hot pressing force on a local area, which can easily lead to uneven force on the floor and deformation problems such as edge warping and middle depression. It mostly relies on simple hydraulic devices and lacks a stable guide and transmission structure, which further increases the risk of product scrapping and makes the curing degree of the floor glue layer inconsistent, affecting the overall structural strength. Rigid support structure is mostly used. During the hot pressing process, the instantaneous impact force directly acts on the multi-layer veneer, causing hidden damage such as internal fiber breakage and glue layer cracking. There is a lack of buffer design, and the vibration generated during hot pressing is transmitted to the entire equipment, which not only aggravates component wear, but also causes slight displacement between the hot pressing template and the floor, further reducing the molding accuracy. Summary of the Invention

This disperses and evens out the hot-pressing force, preventing deformation of the floor caused by excessive local pressure.

The close contact between the positioning base and the multi-layer composite flooring further enhances stability during the hot-pressing process.

A lower hot pressing module 817 is fixedly installed on the bottom of the lower hot pressing module 817. There is a hydraulic rod 818. By setting up a hot pressing forming component 8, four groups of independent hydraulic cylinders 810 are used to work together with the upper hot pressing module 812, and cooperate with multiple groups of evenly distributed hot pressing holes 813 at the bottom to achieve multi-point synchronous hot pressing of the multi-layer composite floor, which can make the hot pressing force more dispersed and more uniform, avoiding deformation of the floor caused by excessive local pressure. At the same time, the four groups of modules working in parallel can increase the single hot pressing area, greatly improve production efficiency, ensure the precise alignment of the upper hot pressing module 812 and the lower hot pressing module 817, and effectively reduce the product scrap rate caused by misalignment.

[0038] Furthermore, multiple groups of identical guide rods 808 are provided, and the multiple groups of guide rods 808 are slidably connected to the lifting hot press 804. By providing multiple groups of guide rods 808 and the lifting hot press 804, the shaking and deviation of the lifting hot press 804 can be effectively limited, making the lifting movement smoother and more precise, ensuring that the upper hot pressing module 812 can be accurately aligned with the lower hot pressing module 817, avoiding the problem of hot pressing misalignment caused by unstable lifting, and greatly improving the hot pressing accuracy.

[0039] Furthermore, the connecting seat 809, the hydraulic cylinder 810, the telescopic rod 811, the upper hot pressing module 812 and the hot pressing hole 813 are provided in four identical groups, and the four groups of connecting seats 809, the hydraulic cylinder 810, the telescopic rod 811, the upper hot pressing module 812 and the hot pressing hole 813 are located at the bottom of the heating machine body 805 and are equidistantly distributed. By providing four groups of connecting seats 809, the hydraulic cylinder 810, the telescopic rod 811, the upper hot pressing module 812 and the hot pressing hole 813, the hot pressing force can be evenly dispersed on the floor surface, avoiding the problem of excessive local pressure caused by a single hot pressing module. The four groups of modules can be controlled independently and can flexibly adjust the pressure according to the characteristics of different areas of the floor, adapt to the hot pressing requirements of various parts of the floor, improve the hot pressing quality, and the four groups of modules working in parallel can significantly increase the single hot pressing area, and the hot pressing efficiency is improved compared to a single module.

[0040] Furthermore, multiple groups of identical hot pressing holes 813 are provided, and the multiple groups of hot pressing holes 813 are evenly distributed on the bottom of the hot pressing module 812. By providing multiple groups of hot pressing holes 813, heat can be more evenly transferred from the heating machine body 805 to the surface of the multi-layer composite floor. The evenly distributed hot pressing holes 813 can make the various areas of the floor heated more evenly, avoiding local overheating or insufficient heating, ensuring that the floor glue layer is cured under the same temperature conditions, improving the firmness and consistency of the glue layer adhesion, and reducing problems such as floor deformation and cracking due to uneven heating.

[0041] Furthermore, multiple identical groups of fixed plates 814, through holes 815, buffer springs 816 and hydraulic rods 818 are provided, and multiple groups of fixed plates 814, through holes 815, buffer springs 816 and hydraulic rods 818 are located on the top of the workbench 1 and are equidistantly distributed. By providing multiple groups of fixed plates 814, through holes 815, buffer springs 816 and hydraulic rods 818, the lower hot pressing module 817 can be subjected to uniform force when bearing the pressure of the upper hot pressing module 812, thereby avoiding deformation of the lower hot pressing module 817 caused by local excessive force. Multiple groups of buffer springs 816 and hydraulic rods 818 can work together to flexibly adjust the supporting force according to the pressure changes during the hot pressing process, thereby better adapting to the hot pressing requirements of floors of different materials and different thicknesses, and improving the compatibility and adaptability of the device.

[0042] Furthermore, the buffer spring 816 has a conical structure, and the hydraulic rod 818 is located inside the buffer spring 816, and the hydraulic rod 818 is adapted to the through hole 815. By setting the hydraulic rod 818 and the through hole 815, the movement trajectory of the lower hot pressing module 817 is ensured to be accurate. The buffer spring 816 with a conical structure has better elastic buffering performance. During the hot pressing process, it can gradually absorb the pressure applied by the upper hot pressing module 812, avoid the rigid impact of the sudden increase in pressure on the multi-layer composite floor, reduce the internal stress concentration of the floor, and can work together with the buffer spring 816 to accurately control the position of the lower hot pressing module 817 while buffering, thereby ensuring the stability and accuracy of the hot pressing process.

[0043] Furthermore, the positioning temperature control component 6 includes a positioning seat 601, which is installed on the inner side of the mounting frame 2, an electromagnetic slide rail 602 is fixedly installed on the top of the positioning seat 601, a mounting seat 603 is fixedly installed on the outer side of the positioning seat 601, a cooling fan 604 is provided on the outer side of the mounting seat 603, and an annular plate 605 is fixedly installed on the bottom of the lifting hot press 804, a temperature control water pipe 606 is provided inside the annular plate 605, and a temperature sensor 607 is provided on the outer side of the annular plate 605. The temperature component 6 realizes automatic and precise positioning of the multi-layer composite base plate body 7 through two sets of symmetrical electromagnetic slide rails 602 and the positioning seat 601, while avoiding random errors caused by human operation. The close contact design between the positioning seat 601 and the multi-layer composite base plate further improves the stability during the hot pressing process. The double sets of temperature-controlled water pipes 606 and temperature sensors 607 inside the annular plate 605 form a closed-loop temperature control system, which can monitor the temperature of the hot pressing area in real time and dynamically adjust it to ensure that the floor glue layer is cured within the optimal temperature range.

[0044] Furthermore, two identical groups of slide grooves 3, positioning seats 601 and electromagnetic slide rails 602 are provided, and the two groups of slide grooves 3, positioning seats 601 and electromagnetic slide rails 602 are symmetrically distributed about the vertical center line of the workbench 1, and the slide grooves 3 are adapted to the electromagnetic slide rails 602. By providing two groups of slide grooves 3, positioning seats 601 and electromagnetic slide rails 602, the multi-layer composite bottom plate body 7 can be positioned from both sides, thereby improving the stability and accuracy of positioning, facilitating adjustment of the position of the positioning seat 601 according to the size of the multi-layer composite bottom plate body 7, and realizing precise positioning of floors of different sizes, thereby avoiding random errors in manual positioning, ensuring the accurate position of the floor during the hot pressing process, and improving the quality of hot pressing.

[0045] Furthermore, the annular plate 605 and the mounting base 603 do not contact each other, and two identical groups of temperature-control water pipes 606 are provided, and the two groups of temperature-control water pipes 606 are symmetrically distributed about the vertical center line of the annular plate 605. By setting the annular plate 605 and the mounting base 603, heat transfer interference between the two can be avoided, ensuring that the temperature-control water pipes 606 and the cooling fan 604 can work independently and efficiently. The temperature-control water pipes 606 can make the temperature distribution around the annular plate 605 more uniform. By cooperating with the temperature sensor 607, the temperature of the hot pressing area can be adjusted in real time, so that the temperature fluctuation is controlled within a normal range, ensuring that the floor glue layer is cured in the optimal temperature range, and at the same time, it can quickly cool down after the hot pressing is completed, thereby improving production efficiency.

[0046] Furthermore, the positioning seat 601 is in contact with the multi-layer composite base plate body 7, and the multi-layer composite base plate body 7 is in contact with both the lower hot pressing module 817 and the upper hot pressing module 812. By setting the multi-layer composite base plate body 7 with the lower hot pressing module 817 and the upper hot pressing module 812, the floor can be well positioned and fixed to prevent the floor from shifting during the hot pressing process. The multi-layer composite base plate body 7 is in contact with the lower hot pressing module 817 and the upper hot pressing module 812, which can ensure that the hot pressing force and heat are evenly transferred to the upper and lower surfaces of the floor, so that the layers of the floor can be fully bonded, thereby improving the overall structural strength and stability of the multi-layer composite floor and ensuring the hot pressing molding effect.

[0047] Working principle: First, before starting the device, the operator needs to conduct a comprehensive inspection of the entire equipment, place the multi-layer composite base plate body 7 on the top of the workbench 1, above the lower hot pressing module 817, and start the electromagnetic slide 602 in the positioning temperature control component 6. Since the slide 3, the positioning seat 601 and the electromagnetic slide 602 are provided with two identical groups and are symmetrically distributed about the vertical center line of the workbench 1, the electromagnetic slide 602 will drive the positioning seat 601 to move along the slide 3, adjust the position of the positioning seat 601, so that the positioning seat 601 contacts the multi-layer composite base plate body 7, and position and fix the multi-layer composite base plate body 7 from both sides to prevent it from displacement during the hot pressing process. Through the precise control of the electromagnetic slide 602, the multi-layer composite base plate body is ensured to be in a stable state. The body 7 is in the correct hot pressing position, corresponding to the positions of the lower hot pressing module 817 and the upper hot pressing module 812. According to the material, thickness and other characteristics of the multi-layer composite bottom plate body 7, the hot pressing parameters are set through the control system. First, the heating temperature of the heating machine body 805 is set. The temperature sensor 607 will monitor the temperature of the hot pressing area in real time to ensure that the temperature can be stably maintained within the set range. Secondly, the pressure parameters of the hydraulic cylinder 810 are set. According to the requirements of floors of different materials, the pressure of the upper hot pressing module 812 on the multi-layer composite bottom plate body 7 is adjusted. At the same time, the hot pressing time is set. Usually, the hot pressing time is determined by the thickness of the floor. The hot pressing time of thicker floors is relatively longer. Start the motor 802, and the motor 802 drives the transmission screw 803 to rotate. Due to the transmission The screw rod 803 is threadedly connected to the lifting hot press 804, and multiple sets of guide rods 808 are slidingly connected to the lifting hot press 804. Under the guidance of the guide rod 808, the lifting hot press 804 will move downward along the transmission screw rod 803, driving the heating machine body 805, the upper hot pressing module 812 and other components to descend together. When the upper hot pressing module 812 descends to close to the multi-layer composite bottom plate body 7, the hydraulic cylinder 810 is started. The hydraulic cylinder 810 pushes the upper hot pressing module 812 to continue to descend through the telescopic rod 811 until the upper hot pressing module 812 contacts the multi-layer composite bottom plate body 7. At this time, the multiple sets of hot pressing holes 813 at the bottom of the upper hot pressing module 812 will evenly transfer the heat generated by the heating machine body 805 to the surface of the multi-layer composite bottom plate body 7. On the surface, since the connecting seat 809, the hydraulic cylinder 810, the telescopic rod 811, the upper hot pressing module 812 and the hot pressing hole 813 are provided with the same four groups and are equidistantly distributed, the four groups of upper hot pressing modules 812 will perform multi-point synchronous hot pressing on the multi-layer composite bottom plate body 7, so that the hot pressing force is evenly dispersed. At the same time, the conical buffer spring 816 and the hydraulic rod 818 at the bottom of the lower hot pressing module 817 will work together. The hydraulic rod 818 slides in the through hole 815 to provide guidance for the lower hot pressing module 817, and the buffer spring 816 absorbs the pressure applied by the upper hot pressing module 812 to avoid internal stress concentration of the multi-layer composite bottom plate body 7 due to rigid contact. During the hot pressing process, the temperature sensor 607 monitors the temperature of the hot pressing area in real time. If the temperature deviates from the set value,The temperature-controlled water pipe 606 will be dynamically adjusted. Through two sets of symmetrically distributed temperature-controlled water pipes 606, the temperature around the annular plate 605 is evenly distributed, ensuring that the floor glue layer is cured within the optimal temperature range. The heat dissipation holes 806 and the exhaust vents 807 on the outside of the heating machine body 805 will dissipate heat in time to prevent the equipment from overheating. After the set hot pressing time is reached, the hydraulic cylinder 810 drives the telescopic rod 811 to contract, so that the upper hot pressing module 812 moves upward and separates from the multi-layer composite bottom plate body 7. Then the motor 802 reverses, driving the transmission screw 803 to rotate in the opposite direction. The lifting hot press 804 moves upward under the guidance of the guide rod 808 and returns to the initial position. The cooling fan 604 is started, and at the same time, the cooling water in the temperature-controlled water pipe 606 is kept circulating to cool the multi-layer composite bottom plate body 7 after hot pressing. Since the annular plate 605 and the mounting base 603 do not contact each other, heat transfer interference is avoided. The cooling fan 604 and the temperature-controlled water pipe 606 can work independently and efficiently, accelerating the cooling speed of the multi-layer composite base plate body 7. After the multi-layer composite base plate body 7 cools to room temperature, the cooling fan 604 and the temperature-controlled water pipe 606 are turned off, and the electromagnetic slide rail 602 is controlled to drive the positioning base 601 to move to the sides, releasing the positioning of the multi-layer composite base plate body 7. The hot-pressed multi-layer composite floor is removed from the workbench 1 for subsequent processing steps such as cutting and polishing. After completing a batch of hot-pressing work, the equipment power is turned off, and the equipment is cleaned and maintained.
