[0002] Bamboo and wood impregnation equipment is mainly used for anti-corrosion, strengthening and beautification treatment of bamboo and wood delignified materials (such as Figure 10 shown). Its working principle usually involves placing bamboo and wood in an impregnating solution, and infiltrating the impregnating solution into the interior of bamboo and wood through vacuum or pressure.

[0003] Reconstituted wood is made from wood / bamboo as raw materials. Through the integration of multiple technologies such as fiber controllable separation technology, veneer flattening technology, manufacturing unit optimization technology, and strengthening unit introduction technology, the wood / bamboo is delignified into veneers for utilization, and high-performance wood-based composite materials are manufactured. The preparation process of reconstituted wood mainly includes: the wood / bamboo raw materials are delignified into wood / bamboo bundles, the wood / bamboo bundles are dried, the wood / bamboo bundles are sized, the sized wood / bamboo bundles are dried after sizing, arranged in parallel along the grain, and then hot-pressed or cold-pressed and heat-cured, etc. Due to the characteristics of high raw material utilization rate, high product performance and added value of reconstituted wood, it can be widely used in indoor and outdoor floors, building beams and columns, furniture, cement formwork, train carriage floors and building props, etc.

[0004] In the prior art, the bamboo and wood impregnation equipment adopts an all-in-one machine method, which occupies a large space and increases transportation costs. Secondly, there are defects in the control of the amount of impregnating glue and the recycling of the glue in the prior art, resulting in a high cost of the glue. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an impregnation device for bamboo and wood materials that can solve the above technical problems in view of the above problems.

[0006] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] An impregnation device for bamboo and wood materials, comprising a first main body with an impregnation tank and a second main body with an impregnating glue collection tank. The first main body and the second main body are arranged in sequence along the conveying direction of the bamboo and wood materials. In the impregnation tank and the impregnating glue collection tank, several groups of roller pressing wheel sets are respectively arranged in sequence along the conveying direction of the bamboo and wood materials. The corresponding roller pressing wheel sets arranged in the impregnation tank roll press the bamboo and wood materials and make the bamboo and wood materials completely immersed in the impregnating glue in the impregnation tank. The corresponding roller pressing wheel sets arranged in the impregnating glue collection tank roll press the impregnated bamboo and wood materials, and the impregnating glue collection tank collects the excess impregnating glue after roller pressing.

[0008] Furthermore, the roller pressing pressure of the corresponding roller pressing wheel sets arranged in the impregnation tank is greater than the roller pressing pressure of the corresponding roller pressing wheel sets arranged in the impregnating glue collection tank.

[0009] Further, along the conveying direction of the bamboo and wood materials, the rolling pressures of the corresponding rolling wheel sets disposed in the impregnation tank are distributed in ascending order.

[0010] Further, along the conveying direction of the bamboo and wood materials, the rolling pressures of the corresponding rolling wheel sets disposed in the impregnation tank are distributed in descending order.

[0011] Further, along the conveying direction of the bamboo and wood materials, the rolling pressures of the corresponding rolling wheel sets disposed in the impregnation tank are equal.

[0012] Further, the rolling pressures of some of the corresponding rolling wheel sets disposed in the impregnation tank are respectively set as rolling pressure A, and the rolling pressures of the remaining rolling wheel sets are respectively set as rolling pressure B; along the conveying direction of the bamboo and wood materials, at least one rolling pressure B is distributed between two adjacent rolling pressures A.

[0013] Further, chip removal mechanisms are respectively disposed at the bottom of the impregnation tank and the impregnation glue collection tank, and the chip removal mechanism is any one of a screw type chip removal mechanism and a crawler type chip removal mechanism.

[0014] Further, the rolling pressures of the corresponding rolling wheel sets disposed in the impregnation glue collection tank are equal or unequal.

[0015] Further, each group of the rolling wheel sets is respectively formed by a moving rolling wheel and a static rolling wheel, and the moving rolling wheel is connected to a rolling wheel pressure adjusting mechanism.

[0016] Further, a first rotation driving mechanism for driving the corresponding rolling wheel sets disposed in the impregnation tank to rotate is disposed on the first main body; a second rotation driving mechanism for driving the corresponding rolling wheel sets disposed in the impregnation glue collection tank to rotate is disposed on the second main body.

[0017] Compared with the prior art, the advantages of the present application are as follows: The device is set as two main bodies, which is convenient for the mobile layout of the device. Multiple rolling wheel sets are designed to make the impregnation of the bamboo and wood materials sufficient and the impregnation glue can be evenly distributed on the bamboo and wood materials. Then, the amount of glue on the bamboo and wood materials can be controlled by the rolling wheels in the impregnation glue collection tank. The chip removal mechanism is set to realize the cleaning of bamboo and wood chips and the repeated recycling of the impregnation glue, thereby reducing the production cost.

[0018] By the split setting of the first main body and the second main body, the maintenance difficulty of the main body (such as chip removal treatment) can be reduced. At the same time, the transportation cost can also be reduced. Description of the Drawings

[0034] Embodiment 1

[0035] As Figures 1-2 shown in this embodiment, the impregnation device for bamboo and wood materials includes a first main body S1 having an impregnation tank 7 and a second main body S2 having an impregnation glue collection tank 8. The first main body S1 and the second main body S2 are arranged in sequence along the conveying direction of the bamboo and wood materials, and a connection groove 71 for transporting the bamboo and wood materials is further provided between the two main bodies. One end of the connection groove 71 is connected to the outlet of the impregnation tank 7 of the first main body S1, and the other end is connected to the inlet of the impregnation glue collection tank 8 of the second main body S2.

[0036] In the impregnation tank 7 and the impregnation glue collection tank 8, there are respectively several groups of roller pressing wheel sets 2 distributed in sequence along the conveying direction of the bamboo and wood materials. The corresponding roller pressing wheel sets 2 arranged in the impregnation tank 7 roll the bamboo and wood materials and immerse the bamboo and wood materials completely in the impregnation glue in the impregnation tank 7. The corresponding roller pressing wheel sets 2 arranged in the impregnation glue collection tank 8 roll the impregnated bamboo and wood materials, and the impregnation glue collection tank 8 collects the excessive impregnation glue after rolling. By setting multiple roller pressing wheel sets 2, it can ensure that the bamboo and wood materials fully contact the impregnation glue in the impregnation tank 7, thereby improving the uniformity and efficiency of impregnation;

[0037] In this embodiment, the rolling pressure of the corresponding roller pressing wheel set 2 arranged in the impregnation tank 7 is greater than the rolling pressure of the corresponding roller pressing wheel set 2 arranged in the impregnation glue collection tank 8. The higher rolling pressure can ensure that the bamboo and wood materials are fully immersed in the impregnation glue in the impregnation tank 7, avoiding uneven impregnation. In the impregnation glue collection tank 8, the lower rolling pressure helps to gently remove the excessive impregnation glue on the surface of the bamboo and wood materials, avoiding uneven glue penetration or material damage caused by excessive extrusion. By setting reasonable pressure, the production efficiency can be improved more effectively.

[0038] One group of the roller pressing wheel sets 2 includes a moving roller pressing wheel 20 and a static roller pressing wheel 21. As Figure 1 shown, the static roller pressing wheel 21 in the impregnation tank 7 is completely immersed in the impregnation glue, and the static roller pressing wheel 21 is always below the liquid level S3. And the moving roller pressing wheel 20 in the impregnation tank 7 is at least partially immersed in the impregnation glue, so that the extrusion channel between the moving roller pressing wheel 20 and the static roller pressing wheel 21 is always immersed in the impregnation glue, enabling the bamboo and wood materials to fully absorb the impregnation glue when being extruded. The moving roller pressing wheel 20 moves up and down through a roller pressing wheel pressure regulating mechanism to ensure that the pressure received by the bamboo and wood materials can always be maintained within a reasonable range.

[0039] Among them, the roller pressing wheel set 2 can be any one of a smooth wheel and a patterned wheel. In this embodiment, the roller pressing wheel set 2 in the impregnation tank 7 is set as a smooth wheel, while the roller pressing wheel set 2 in the impregnation glue collection tank 8 is set as a patterned wheel.

[0040] To ensure the synchronization of the rotation of the moving roller pressing wheel 20 and the static roller pressing wheel 21 in the roller pressing wheel set 2, as Figure 2 shown, on the first main body S1, there is a first rotation driving mechanism 70 for driving the corresponding roller pressing wheel set 2 arranged in the impregnation tank 7 to rotate; the first rotation driving mechanism 70 includes a synchronous gear 201 arranged at one end of the moving roller pressing wheel 20, and a driving gear 211 arranged on the same group of static roller pressing wheel 21 and meshing with the synchronous gear. This design enables the moving roller pressing wheel 20 and the static roller pressing wheel 21 in the same group to always maintain the same rotational speed, enabling the bamboo and wood materials to maintain a stable speed and force during the rolling process, and ensuring a more ideal soaking effect in the impregnation glue.

[0041] Regarding the drive gear 211 on the static roller 21 mentioned above, as Figures 2-3 shown in this embodiment, the drive gears 211 between two adjacent roller groups 2 in the first main body S1 are connected by a transmission chain. Finally, all the drive gears 211 are connected to a drive device through the transmission chain. The drive device is a power device such as a servo motor. Similarly, a second rotation drive mechanism 80 for driving the corresponding roller group 2 provided in the impregnating glue collection tank 8 to rotate is provided on the second main body S2. The same components on the second main body S2 adopt the same design as those on the first main body S1 to reduce the manufacturing cost of the equipment.

[0042] During the roller pressing process of the bamboo and wood materials, some bamboo and wood debris will fall off due to extrusion on the bamboo and wood materials. The bamboo and wood debris will remain in the impregnating tank 7 and the impregnating glue collection tank 8. Excessive bamboo and wood debris will affect the roller pressing effect of the equipment. Therefore, the equipment further includes a chip discharging mechanism 9 provided at the bottom of the impregnating tank 7 and the impregnating glue collection tank 8. The chip discharging mechanism 9 is any one of a screw type chip discharging mechanism and a crawler type chip discharging mechanism. As Figure 1 shown in this embodiment, the chip discharging mechanism 9 is a screw type chip discharging mechanism, which includes a horizontally placed screw 90 at the bottommost end and a drive motor provided at one end of the screw 90. The drive motor can make the screw rotate stably around the axis. The chip discharging outlet is at the end of the screw 90 far from the drive motor. The bamboo and wood debris and part of the impregnating glue will be discharged from the impregnating tank 7 and the impregnating glue collection tank 8 to the outside of the equipment under the drive of the rotation of the screw 90. A waste pool 91 is also provided outside the equipment. The waste pool 91 is designed to filter and separate the bamboo and wood debris from the discharged impregnating glue, so that the impregnating glue can be reused to reduce the production cost.

[0043] Embodiment 2

[0044] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The different structure lies in that for the impregnating equipment for bamboo and wood materials in the above-mentioned Embodiment 1, this embodiment specifically describes the roller pressure adjusting mechanism in the impregnating equipment for bamboo and wood materials.

[0045] As Figures 4-5 shown, the impregnating equipment includes a frame 1. At least one roller group 2 is provided on the frame 1. The roller group 2 is formed by a moving roller 20 and a static roller 21. In this embodiment, the moving roller 20 and the static roller 21 are vertically distributed up and down. The static roller 21 is relatively fixed to the frame 1, and the moving roller 20 can move up and down relative to the static roller 21 on the frame to match the real-time thickness of the bamboo and wood materials entering the impregnating equipment.

[0046] Among them, pressure sensors 5 for detecting the rolling pressure of the moving roller 20 are also provided at both ends of the rotating shaft of the moving roller 20. The pressure sensors 5 enable real-time monitoring of the rolling pressure, ensuring that it always remains within the set range during the impregnation process, improving the impregnation quality. The pressure sensors 5 are connected to a controller, and the controller uses the lifting adjustment assembly 4 to adjust the height of the moving roller 20, thereby achieving the effect of controlling the pressure between the moving roller 20 and the static roller 21.

[0047] 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, as Figures 5-6 shown. The lifting adjustment assembly 4 is fixed to the adaptive adjustment plate 10, and the moving roller 20 is connected to the adaptive adjustment plate 10 through the lifting adjustment assembly 4. The above elastic component 3 always exerts a force on the adaptive adjustment plate 10 pointing to the frame 1, fixing the adaptive adjustment plate 10 to the frame 1. Through the design of the elastic component 3 and the adaptive adjustment plate 10, combined with the lifting adjustment assembly 4, it can automatically adjust the pressure and buffer of the roller in the first time according to the material characteristics and changes during the impregnation process, ensuring the best impregnation effect.

[0048] Specifically, the elastic component 3 can be any one or a combination of two of an elastic gasket component and a spring. In this embodiment, elastic gasket components are provided on both sides of the frame 1 in the direction of the rotating shaft of the moving roller 20, but this design method is not limited, and it can be designed and changed according to actual working requirements and strength. The advantage of designing the elastic gasket component is that it can provide a uniform pressure distribution between the contact surfaces, avoid local overload, ensure the stability of the adaptive adjustment plate 10, and at the same time, the elastic gasket is more stable and safe in the elastic force direction than the spring, and has a smaller replacement difficulty during maintenance.

[0049] Specifically, the above elastic component 3 includes several rod bodies 30 fixed to the frame 1 at the lower end. In this embodiment, there are four rod bodies 30 and they are respectively located at the corresponding corners of the adaptive adjustment plate 10. The rod bodies 30 penetrate upward through the adaptive adjustment plate 10, and at the same time, elastic members 31 are sleeved on the rod bodies 30, as Figure 6As shown, the elastic member 31 is a number of stacked elastic gaskets. At the upper end of the rod body 30, an elastic force adjusting member 32 is threadedly connected. The specific installation sequence is as follows: First, the rod body 30 is connected to the frame 1 by welding or other means. Then, the adaptive adjusting plate 10 is sleeved on the rod body 30 through the corresponding avoidance holes. Then, a number of elastic members 31 are stacked and sleeved on the rod body 30. Finally, the elastic force adjusting member 32 is threadedly connected and tightened to generate an adaptive pressure acting downward on the adaptive adjusting plate 10. The elastic force adjusting member 32 includes at least one nut. The combined action of multiple nuts prevents the nut of the elastic force adjusting member 32 from loosening during the operation of the equipment, causing danger. At the same time, to prevent large local stresses from being generated on the contact surfaces between the elastic member 31 and the frame 1 and the elastic force adjusting member 32, a reinforcing ring 33 that increases the contact area and evenly distributes the pressure is provided between the elastic member 31 and the frame 1, and between the elastic member 31 and the elastic force adjusting member 32, thereby improving the service life of the entire equipment.

[0050] The lifting adjustment assembly 4 for adjusting the height of the moving roller press wheel 20 can be any one of a screw-driven assembly and a worm and worm wheel-driven assembly. In this embodiment, the lifting adjustment assembly 4 is a screw-driven assembly, such as Figure 6 As shown, the lifting adjustment assembly 4 includes roller press wheel seats 40 sleeved on the axial two ends of the moving roller press wheel 20 and in lifting and sliding fit with the frame 1. On the adaptive adjusting plate 10, a screw seat 41 with a threaded hole is provided. A vertical screw 42 is threadedly connected in the threaded hole of the screw seat 41, and the lower end of the vertical screw 42 is rotatably connected to the corresponding roller press wheel seat 40. Through the connection between the threaded hole and the vertical screw 42, precise lifting adjustment can be achieved, ensuring that the height of the moving roller press wheel 20 can be finely adjusted as needed, thereby optimizing the impregnation effect. At the same time, during maintenance, it can prevent the accidentally dropped moving roller press wheel 20 from causing accidents when lifted. A pressure sensor 5 as described above is provided between the vertical screw 42 and the roller press wheel seat 40. The pressure sensor 5 is annular. The vertical screw 42 passes through the pressure sensor 5 and the pressure sensor 5 is fixed to the top side of the roller press wheel seat 40. The direct contact design of the annular pressure sensor 5 with the roller press wheel seat 40 enables the pressure change to be quickly transmitted to the sensor, improving the response speed and ensuring real-time monitoring.

[0051] The vertical screw 42 is driven by one power source or by power sources at both ends respectively. 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 one power source, such as Figure 9 As shown, a transmission rod 43 is horizontally arranged between the two screw seats 41 for transmitting power and synchronizing the movement of the two vertical screws 42, such as Figures 7-9 As shown, driving worm wheels 44 meshing with the vertical screws 42 are respectively provided at both ends of the transmission rod 43. The transmission rod 43 is connected to the servo motor 6.

[0052] Example 3

[0053] The structure and principle of this example are basically the same as those of Example 1 and Example 2. This example will describe different pressure combination methods of the roller pressing wheel sets.

[0054] In this example, as Figure 10 shown in the schematic diagram of the bamboo and wood delignification material example, to improve the impregnation effect of the bamboo and wood materials, at least three groups of roller pressing wheel sets 2 are provided in the impregnation tank 7. Among them, according to the characteristics of the actual bamboo and wood materials and the changes during the impregnation process, in the conveying direction of the bamboo and wood materials, the following several pressure combination methods of the roller pressing wheel sets can be divided:

[0055] I. The roller pressing pressures of the roller pressing wheel sets 2 are equal

[0056] All the roller pressing wheels apply the same pressure to ensure uniform impregnation of the materials, avoid local overload or deficiency, and are suitable for most materials, especially bamboo and wood materials with similar characteristics, and can provide a good impregnation effect.

[0057] II. The roller pressing pressures of the roller pressing wheel sets 2 alternate in magnitude

[0058] In this method, the three groups of roller pressing wheel sets 2 are arranged with small-large-small or large-small-large pressures respectively. For example, the roller pressing pressures of some of the roller pressing wheel sets 2 provided in the impregnation tank 7 are respectively set as the roller pressing pressure A, and the roller pressing pressures of the remaining roller pressing wheel sets 2 are respectively set as the roller pressing pressure B; in the conveying direction of the bamboo and wood materials, there is at least one roller pressing pressure B distributed between two adjacent roller pressing pressures A.

[0059] Through the combination of roller pressing wheels with different pressures, the bamboo and wood materials can be alternately pressed, and the alternating pressure changes can promote the penetration of the impregnating liquid and ensure that the liquid can penetrate deep into the material interior.

[0060] III. The roller pressing pressures of the roller pressing wheel sets 2 are distributed in ascending order

[0061] The gradually increasing pressure can effectively promote the deep penetration of the impregnating liquid and ensure sufficient wetting inside the material. By gradually increasing the pressure, the impregnation process can be better controlled, and the damage of the material caused by excessive pressure can be avoided.

[0062] IV. The roller pressing pressures of the roller pressing wheel sets 2 are distributed in descending order

[0063] This method achieves a similar effect to the third method, both aiming to protect the bamboo and wood materials and control the impregnation process to 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 impregnating liquid and improve the impregnation effect.

[0064] Similarly, in this embodiment, the rolling pressure of the corresponding rolling wheel set 2 in the impregnating glue collecting tank 8 can be set in some combination ways that are equal or unequal to the rolling pressure of the rolling wheel set 2 in the impregnating tank 7, so as to achieve a better effect of rolling the excess impregnating glue.

[0065] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
