[0028] The embodiments of this utility model 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 this utility model, and should not be construed as limiting this utility model.
[0029] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.
[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0031] The following is combined with Figures 1 to 5 The embodiments of this utility model are described below.
[0032] This utility model embodiment provides a wood-imitation bending machine, comprising:
[0033] frame;
[0034] A bending platform 100 is mounted on the frame;
[0035] The lower pressure roller group includes a plurality of lower pressure rollers 200, which are spaced apart on the bending platform 100 along the front-back direction.
[0036] The upper pressure roller group includes multiple upper pressure rollers 300, which are movable up and down on the frame. The multiple upper pressure rollers 300 are arranged alternately with the multiple lower pressure rollers 200 along the front and back direction of the bending platform 100.
[0037] Two sets of clamping mechanisms 700 are respectively disposed at the front and rear ends of the bending platform 100, and the two sets of clamping mechanisms 700 are respectively used to clamp the front and rear ends of the imitation wood.
[0038] In this embodiment, the bending platform 100 serves as the core load-bearing component, providing a stable installation foundation for key components such as the lower pressure roller group and the clamping mechanism 700.
[0039] In the bending process of imitation wood, this embodiment achieves a wavy bending effect by employing staggered upper and lower pressure roller groups. Specifically, multiple lower pressure rollers 200 of the lower pressure roller group are arranged at intervals along the front-back direction of the bending platform 100, while multiple upper pressure rollers 300 of the upper pressure roller group are mounted on the frame and are arranged alternately with the lower pressure rollers 200. This allows the upper pressure roller group to move up and down according to processing requirements during the bending operation of the imitation wood, cooperating with the lower pressure roller group to apply alternating pressure at different positions on the imitation wood. Under the staggered pressure of the upper and lower pressure rollers 200, the imitation wood undergoes bending deformation, thus obtaining a wavy bending effect. Compared with traditional bending methods, this wavy bending can meet more diverse imitation wood shaping needs, providing richer possibilities for the application of imitation wood in decoration, furniture, and other fields.
[0040] Furthermore, during the processing of the imitation wood, this embodiment uses two sets of clamping mechanisms 700 to clamp the front and rear ends of the imitation wood respectively, keeping the imitation wood in a taut state during bending. This not only helps to improve the stability of the imitation wood during bending and avoid processing errors caused by loosening of the imitation wood, but also allows the imitation wood to be subjected to more uniform force during the wavy bending process, reducing the occurrence of problems such as excessive local deformation or wrinkles, thereby improving the processing accuracy and finished product quality of the imitation wood bending.
[0041] Furthermore, the wood-imitation bending machine also includes multiple sets of screw drive mechanisms, which are fixedly mounted on the frame. Each set of screw drive mechanisms drives a single upper pressure roller 300 to move up and down.
[0042] In this embodiment, multiple independent screw drive mechanisms enable individual control of the up-and-down movement of each upper pressure roller 300. This allows for adjustment of the downward pressure of each upper pressure roller 300 according to different bending requirements, thereby achieving diverse bending effects and improving the applicability of the equipment.
[0043] Further, the lead screw transmission mechanism includes a first motor 401, a first support 402, a first lead screw 403, a first slider 404, a first nut, and a first guide rail 405. The first support 402 is fixedly mounted on the frame, the first motor 401 is fixedly mounted on one end of the first support 402, the first lead screw 403 is rotatably mounted on the first support 402, and the first lead screw 403 is connected to the output shaft of the first motor 401. The first nut is mounted on the first slider 404, the first lead screw 403 passes vertically through the first slider 404 and is threadedly engaged with the first nut, the first guide rail 405 is fixedly mounted on the first support 402, the first guide rail 405 extends vertically along the bending platform 100, and the first slider 404 moves along the first guide rail 405. Guide rods 4041 are fixedly connected to both ends of the first slider 404, the guide rods 4041 extend downwards, and the two guide rods 4041 rotate between each other. A pressure roller shaft 301 is connected to the bending platform 100, and the upper pressure roller 300 is fixedly sleeved on the upper pressure roller shaft 301. Multiple upper pressure roller guide frames 500 are provided on the bending platform 100, and the multiple upper pressure roller guide frames 500 are arranged at intervals along the front-rear direction of the bending platform 100. Each upper pressure roller guide frame 500 includes a transverse support portion 501 located above a single upper pressure roller 300. The transverse support portion 501 extends along the left-right direction of the bending platform 100, and both ends of the transverse support portion 501 are fixed. Vertical guide sections 502 are fixedly connected to the bending platform 100. The vertical guide sections 502 extend downward and are fixedly connected to the bottom of the bending platform 100. A guide hole is provided on the upper surface of the vertical guide section 502, through which the guide rod 4041 passes. Avoidance grooves 5021 are provided on the left and right sides of the vertical guide section 502. The avoidance grooves 5021 extend along the vertical direction of the bending platform 100 and are used to avoid the upper pressure roller shaft 301.
[0044] In this embodiment, the first motor 401 drives the first lead screw 403 to rotate, which in turn drives the first slider 404 to move linearly along the first guide rail 405. At the same time, the upper pressure roller guide frame 500 further provides a stable guiding structure. The guide rod 4041 passes through the guide hole to ensure that the upper pressure roller 300 maintains linear motion during the up and down movement, avoiding tilting or shaking. The design of the clearance groove 5021 provides sufficient movement space for the upper pressure roller shaft 301.
[0045] Furthermore, the lower pressure roller assembly also includes a plurality of lower pressure roller seats 600, which are arranged at intervals at the left and right ends of the bending platform 100 along the front-back direction of the bending platform 100. A lower pressure roller shaft 201 is rotatably connected between the left and right lower pressure roller seats 600, and the lower pressure roller 200 is fixedly sleeved on the lower pressure roller shaft 201.
[0046] In this embodiment, multiple pressure roller seats 600 are arranged at intervals along the front and rear direction of the bending platform 100, providing stable support for the pressure roller 200. This allows the pressure roller 200 to bear the pressure evenly during the bending process, ensuring that the imitation wood material is subjected to uniform force during the bending process and effectively preventing local deformation or damage to the material.
[0047] Further, the lower pressure roller seat 600 includes a horizontal adjustment part 601 and a vertical support part 602. The horizontal adjustment part 601 extends along the front-rear direction of the bending platform 100, and the vertical support part 602 extends along the vertical direction of the bending platform 100. The lower surface of the vertical support part 602 is fixedly connected to the upper surface of the horizontal adjustment part 601. The lower pressure roller shaft 201 is rotatably connected between the left and right vertical support parts 602. A horizontal adjustment groove 6011 is provided on the upper surface of the horizontal adjustment part 601. The horizontal adjustment groove 6011 passes through the horizontal adjustment part 601 in the vertical direction and extends along the front-rear direction of the bending platform 100. The bending platform 100 is provided with a plurality of horizontal fixing holes 101. The lower pressure roller seat 600 also includes a horizontal fixing nail. The horizontal fixing nail passes through the horizontal adjustment groove 6011 and is threadedly connected to the horizontal fixing hole 101.
[0048] In this embodiment, the horizontal adjustment groove 6011 and the horizontal fixing nail are designed to adjust the front and rear positions of the lower pressure roller 200 according to the actual bending requirements.
[0049] Furthermore, the vertical support 602 is provided with a pivot hole 6021, and the lower pressure roller shaft 201 is rotatably connected between the left and right lower pressure roller seats 600 through the two pivot holes 6021; there are multiple pivot holes 6021, and the multiple pivot holes 6021 are distributed at intervals along the vertical direction of the vertical support 602.
[0050] In this embodiment, multiple pivot holes 6021 are distributed vertically on the vertical support 602, thereby allowing the lower pressure roller shaft 201 to adjust its vertical position by selecting pivot holes 6021 at different heights. Thus, the lower pressure roller 200 can be flexibly adjusted in its vertical position according to the bending process requirements.
[0051] Furthermore, the lower surface of the vertical support 602 is fixedly connected to the middle of the upper surface of the horizontal adjustment part 601, and the upper surface of the horizontal adjustment part 601 is divided into a front upper surface 6012 and a rear upper surface 6013, and the horizontal adjustment groove 6011 is respectively provided on the front upper surface 6012 and the rear upper surface 6013.
[0052] In this embodiment, the vertical support 602 divides the horizontal adjustment part 601 into a front upper surface 6012 and a rear upper surface 6013, and provides horizontal adjustment grooves 6011 for each. This design makes the lower pressure roller seat 600 more stable during the front and rear position adjustment process and less prone to rotation and misalignment. At the same time, the lower pressure roller seat 600 is fixed with horizontal fixing nails at both the front and rear, which makes it more stable in supporting the lower pressure roller 200.
[0053] Furthermore, the clamping mechanism 700 includes an upper clamping roller 701 and a lower clamping roller 702. Both the upper clamping roller 701 and the lower clamping roller 702 are mounted on the bending platform 100 and can move up and down. The upper clamping roller 701 and the lower clamping roller 702 are arranged parallel to each other.
[0054] In this embodiment, the upper clamping roller 701 and the lower clamping roller 702 can move up and down and are arranged in parallel, which can firmly clamp both ends of the imitation wood material. During the bending process, this clamping method effectively prevents the material from sliding or shifting, ensuring the accuracy of the bending operation, while also helping to improve production efficiency and reduce operational errors caused by material displacement.
[0055] Furthermore, the clamping mechanism 700 also includes two sets of guide rods 703, which are respectively disposed at the left and right ends of the bending platform 100. The guide rods 703 extend along the vertical direction of the bending platform 100. An upper limit block 7031 is formed at the top end of the guide rod 703, and a lower limit block 7032 is formed at the bottom end of the guide rod 703. The diameters of the upper limit block 7031 and the lower limit block 7032 are both larger than the diameter of the guide rod 703. The lower limit block 7032 is fixedly connected to the bending platform 100. An upper clamping roller slider 704 and an upper clamping roller slider 704 are sleeved on the guide rod 703. An upper clamping roller slider 704 is rotatably connected between the left and right upper clamping roller sliders 704. A holding roller shaft 7011 is provided, and the upper clamping roller 701 is fixedly sleeved on the upper clamping roller shaft 7011. A lower clamping roller shaft 7021 is rotatably connected between the left and right lower clamping roller sliders 705. The lower clamping roller 702 is fixedly sleeved on the lower clamping roller shaft 7021. An upper limit spring 706 and a lower limit spring 707 are also sleeved on the guide rod 703. One end of the upper limit spring 706 abuts against the upper surface of the upper clamping roller slider 704, and the other end of the upper limit spring 706 abuts against the lower surface of the upper limit block 7031. One end of the lower limit spring 707 abuts against the lower surface of the lower clamping roller slider 705, and the other end of the lower limit spring 707 abuts against the upper surface of the lower limit block 7032.
[0056] In this embodiment, the upper limit spring 706 and the lower limit spring 707 act on the upper clamping roller slider 704 and the lower clamping roller slider 705, respectively. Through elastic force, the upper clamping roller 701 and the lower clamping roller 702 maintain a tendency to clamp towards the center. This allows for automatic adjustment of the clamping force according to the cross-sectional dimensions of the imitation wood, ensuring that imitation wood of different thicknesses can be stably clamped during processing, avoiding positional shifts or slippage due to loose clamping. During the bending process, when the imitation wood bends under the action of the upper and lower pressure rollers, both ends of the imitation wood will experience a certain vertical displacement along the bending arc. At this time, the upper clamping roller slider 704 and the lower clamping roller slider 705 can slide up and down along the guide rod 703. Combined with the elastic buffering of the limit springs, the upper and lower clamping rollers can synchronously adapt to the bending deformation of the imitation wood, continuously maintaining the clamping force on the imitation wood during the dynamic process.
[0057] Furthermore, heating wires 800 are provided at both ends of the bending platform 100.
[0058] In this embodiment, heating wires 800 are installed at both ends of the bending platform 100, which can heat the imitation wood material. The heated material has enhanced plasticity, making it easier to form the required arc shape during the bending process. This reduces the generation of internal stress in the material and lowers the risk of cracking and breaking of the imitation wood material, thereby improving the quality and yield of the product.
[0059] The preferred embodiments of the present invention have been described in detail above, but the present disclosure is not limited to the embodiments described.
