Description

Technical Field

[0001] The present application belongs to the field of bamboo and wood processing equipment, and in particular relates to a roller pressure adjustment mechanism of an impregnation equipment. Background Art

[0002] Bamboo and wood impregnation equipment is mainly used for bamboo and wood decomposition materials (such as Figure 7 The working principle usually involves placing the bamboo wood in an impregnation liquid, which is then infiltrated into the bamboo wood by vacuum or pressure.

[0003] Recombinant wood is made from wood / bamboo materials. Through the integration of multiple technologies, including controlled fiber separation, veneer flattening, manufacturing unit optimization, and reinforcement unit introduction, the wood / bamboo materials are decomposed into veneers for utilization, resulting in high-performance wood composite materials. The recombinant wood production process primarily involves decomposing the wood / bamboo materials into bundles, drying the bundles, gluing the bundles, drying the bundles after gluing, assembling the bundles along the grain, and then hot or cold pressing and curing. Due to its high raw material utilization, high product performance, and added value, recombinant wood is widely used in interior and exterior flooring, building beams and columns, furniture, cement formwork, train car floors, and structural bracing.

[0004] In the prior art, patent CN 218614590 U discloses a roller-pressed resin impregnation device. The device includes a frame equipped with a drive motor, which is in transmission connection with an active roller. A passive roller is positioned above and parallel to the active roller, and a roller-lifting device is positioned above the passive roller for adjusting the height of the passive roller. The passive roller is also equipped with a pressure detection device. The roller spacing is automatically adjusted, with the roller-lifting device driving the passive roller up and down, thereby achieving precise control of the gap between the active and passive rollers. The pressure detection device also synchronously detects real-time pressure data from the rollers, enabling real-time detection of roller pressure. Although the pressure control systems in the aforementioned patents and conventional bamboo and wood impregnation equipment have real-time pressure detection capabilities, the sensor's response time is insufficient to adjust the roller spacing in a timely manner under rapidly changing operating conditions, affecting the impregnation effect. If the device fails to adjust the spacing in a timely manner, improper pressure can damage the decomposed material or the roller assembly. Utility Model Content

[0030] Example 1

[0031] like Figure 1-Figure 2 As shown, the impregnation equipment includes a frame 1, on which is provided at least one set of roller pressing wheels 2, which is formed by a dynamic roller pressing wheel 20 and a static roller pressing wheel 21. In this embodiment, the dynamic roller pressing wheel 20 and the static roller pressing wheel 21 are vertically distributed up and down, and the static roller pressing wheel 21 is relatively fixed to the frame 1. The dynamic roller pressing wheel 20 can move up and down on the frame relative to the static roller pressing wheel 21 to match the real-time thickness of the decomposed material entering the impregnation equipment;

[0032] Pressure sensors 5 are provided at both ends of the rotating shaft of the dynamic roller 20 to detect the rolling pressure of the dynamic roller 20. These sensors enable real-time monitoring of the rolling pressure, ensuring that it remains within a set range during the impregnation process, thereby improving the impregnation quality. The pressure sensors 5 are connected to a controller, which uses a lifting and adjusting assembly 4 to adjust the height of the dynamic roller 20, thereby controlling the pressure between the dynamic roller 20 and the static roller 21. The controller is a commercially available PLC. The pressure sensor 5 and the controller are connected by wire.

[0033] In order to improve the fault tolerance of the control system and maintain the stable operation of the impregnation equipment, the roller pressure adjustment mechanism includes an adaptive adjustment plate 10 connected to the frame 1 through an elastic component 3 in the vertical direction, such as Figure 2-Figure 3 As shown, the lifting and adjusting assembly 4 is fixed to the adaptive adjustment plate 10, and the movable roller 20 is connected to the adaptive adjustment plate 10 via the lifting and adjusting assembly 4. The elastic assembly 3 mentioned above always applies a force directed toward the frame 1 on the adaptive adjustment plate 10, fixing the adaptive adjustment plate 10 to the frame 1. The design of the elastic assembly 3 and the adaptive adjustment plate 10, combined with the lifting and adjusting assembly 4, can automatically adjust the roller pressure and buffer according to the characteristics of the material and changes during the impregnation process, ensuring the best impregnation effect.

[0034] It is particularly noted that the elastic component 3 can be any one of an elastic gasket component and a spring, or a combination of the two. In this embodiment, elastic gasket components are provided on both sides of the frame 1 in the direction of the rotating axis of the movable roller pressure wheel 20. However, this design is not limited to this and can be modified according to actual working requirements and strength. The advantage of designing an elastic gasket component is that it can provide uniform pressure distribution between the contact surfaces, avoid local overload, and ensure the stability of the roller adaptive adjustment plate 10. At the same time, compared with springs, elastic gaskets are more stable and safer in the direction of elastic force, and are less difficult to replace during maintenance.

[0035] Specifically, the elastic component 3 includes a plurality of rods 30 whose lower ends are fixed to the frame 1. In this embodiment, there are four rods 30 and they are respectively located at corresponding corners of the adaptive adjustment plate 10. The rods 30 pass through the adaptive adjustment plate 10 upwards. At the same time, an elastic member 31 is sleeved on the rods 30. Figure 3As shown, the elastic member 31 is a plurality of stacked elastic gaskets, and an elastic adjustment member 32 is threadedly connected to the upper end of the rod body 30. The specific installation sequence is as follows: first, the rod body 30 and the frame 1 are connected together by welding or the like, and the adaptive adjustment plate 10 is sleeved in the rod body 30 through the corresponding avoidance hole, and a plurality of elastic members 31 are stacked and sleeved on the rod body 30. Finally, the elastic adjustment member 32 is threadedly connected and tightened to generate an adaptive pressure acting downward on the adaptive adjustment plate 10, wherein the elastic adjustment member 32 includes at least one nut, and the multiple nuts work together to prevent the elastic adjustment member 32 from loosening when the equipment is running, causing danger; at the same time, in order to prevent the elastic member 31 from generating large local stress on the contact surface with the frame 1 and the elastic adjustment member 32, a reinforcement ring 33 is provided between the elastic member 31 and the frame 1, and between the elastic member 31 and the elastic adjustment member 32 to increase the contact area and uniform pressure, thereby improving the service life of the entire equipment.

[0036] The lifting and adjusting component 4 for adjusting the height of the movable roller pressure wheel 20 can be any one of a screw drive component and a worm gear drive component. In this embodiment, the lifting and adjusting component 4 is a screw drive component, such as Figure 3 As shown, the lifting and lowering adjustment component 4 includes a roller pressing wheel seat 40 which is sleeved on the axial ends of the movable roller pressing wheel 20 and is matched with the frame 1 for lifting and sliding. A screw seat 41 with a threaded hole is provided on the adaptive adjustment plate 10, and a vertical screw 42 is threadedly connected to the threaded hole of the screw seat 41, and the lower end of the vertical screw 42 is rotatably connected to the corresponding roller pressing wheel seat 40. Through the connection between the threaded hole and the vertical screw 42, precise lifting and lowering adjustment can be achieved to ensure that the height of the movable roller pressing wheel 20 can be fine-tuned as needed, thereby optimizing the impregnation effect. At the same time, during maintenance, the lifted movable roller pressing wheel 20 can be prevented from accidentally falling and causing accidents. The above-mentioned pressure sensor 5 is provided between the vertical screw 42 and the roller pressing wheel seat 40. The pressure sensor 5 is annular, and the vertical screw 42 passes through the pressure sensor 5 and the pressure sensor 5 is fixed to the top side of the roller pressing wheel seat 40. The direct contact design of the annular pressure sensor 5 and the roller pressing wheel seat 40 enables the pressure change to be quickly transmitted to the sensor, thereby improving the response speed and ensuring real-time monitoring.

[0037] The vertical screw 42 is driven by a single power source or by power sources at both ends. This design provides flexible power selection to adapt to different production requirements and operating conditions. In this embodiment, the vertical screw 42 is driven by a single power source, wherein a transmission rod 43 is placed horizontally between the two screw seats 41 for transmitting power and synchronizing the movement of the two vertical screws 42. Figure 4-Figure 6 As shown, both ends of the transmission rod 43 are provided with driving worm gears 44 meshing with the vertical screw rod 42 , and the transmission rod 43 is connected to the servo motor 6 .

[0038] Example 2

[0039] The structure and principle of this embodiment are basically the same as those of the first embodiment. The difference lies in that, for the rolling wheel assembly of the first embodiment, this embodiment will describe a different rolling wheel assembly pressure combination method.

[0040] In this embodiment, in order to improve the impregnation effect of the decomposed material, at least three sets of roller groups 2 are provided. According to the actual characteristics of the decomposed material and the changes during the impregnation process, the following roller group pressure combinations can be used:

[0041] 1. The pressure is the same at all levels

[0042] All rollers apply the same pressure to ensure uniform impregnation of the material and avoid local overload or underload. It is suitable for most materials, especially the decomposed materials with similar characteristics, and can provide good impregnation effect.

[0043] 2. Pressure alternation

[0044] In this way, the three groups of roller pressing wheels 2 are arranged with small or large pressures respectively. By combining roller pressing wheels with different pressures, alternating pressure can be applied to the decomposed material. The alternating pressure changes can promote the penetration of the impregnation liquid and ensure that the liquid can penetrate deep into the material.

[0045] 3. Pressure increases step by step

[0046] The gradually increasing pressure can effectively promote the deep penetration of the impregnation liquid and ensure sufficient infiltration of the material. By gradually increasing the pressure, the impregnation process can be better controlled to avoid material damage caused by excessive pressure.

[0047] 4. Pressure decreases step by step

[0048] This method achieves similar effects to the third method. Both methods control the impregnation process to protect the decomposed material and avoid material damage caused by excessive pressure. At the same time, at the end of the impregnation, gradually reducing the pressure can help the material better absorb the impregnation liquid and improve the impregnation effect.

[0049] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
