Description

Technical Field

[0001] This utility model relates to the field of wood processing, and more specifically, to a veneer press for wood processing. Background Technology

[0002] Wood processing refers to the process of using wood as raw material and processing it through mechanical or chemical methods to transform logs into various wood products. It encompasses sawing, drying, gluing, shaping, and surface treatment, producing products such as boards, furniture, flooring, and decorative components. Its purpose is to optimize wood performance, improve utilization, and endow wood with specific functions. It is widely used in construction, furniture manufacturing, and interior decoration. A veneer press is a key piece of equipment in wood processing, mainly used to bond veneer materials to a substrate using pressure and heat or adhesives. During operation, the equipment generates uniform pressure through hydraulic or mechanical transmission, ensuring a tight bond between the veneer material and the substrate, guaranteeing a firm bond and a smooth surface, avoiding defects such as bubbles and warping. It is commonly used for surface treatment of furniture panels and decorative boards to improve product appearance and performance.

[0003] A search revealed an existing patent (publication number: CN222406217U) disclosing a press for aligning wood, comprising a base, a frame fixedly connected to the top end face of the base, the frame being sleeved with a hydraulic rod, a transmission rod fixedly connected to the output end of the hydraulic rod, an upper pressure plate fixedly connected to the bottom end face of the transmission rod, and an adjustment component provided on the top end face of the upper pressure plate. In this press for aligning wood, the inclined edge of the adjustment block contacts the wood panel, pushing the panel towards the center of the base, thereby aligning multiple panels. The inclined edge of the adjustment block has toothed grooves; when the panel passes over these grooves, vibration is generated, disrupting the adhesion between the smooth panels and facilitating the alignment process. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] Existing wood processing presses rely primarily on the beveled edge of the adjusting block to contact the board for positioning and alignment. This design ensures good positioning accuracy when processing boards of similar size, but when dealing with boards of significantly different sizes, the fixed angle and length of the beveled edge prevent the beveled edge from effectively fitting the board edge when the board width or other specifications exceed its adaptability range. This results in either an insufficient contact area leading to unstable positioning or insufficient bevel length to cover the board edge, making accurate alignment difficult. This limits the press's adaptability to boards of different sizes and reduces the flexibility of veneer positioning.

[0005] Therefore, a veneer press for wood processing is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a veneer press for wood processing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wood veneer press, comprising a worktable, a support base fixedly connected to one side of the worktable, a pressure application component fixedly installed on the upper surface of the support base, a positioning plate fixedly installed on the upper surface of the worktable, a transmission base fixedly installed on the bottom surface of the worktable, two bearing rings fixedly embedded in the inner wall of the transmission base, a positive and negative lead screw fixedly connected to the inner rings of the two bearing rings, two threaded sliders threadedly connected to the outer surface of the positive and negative lead screws, two movable plates fixedly connected to the outer surface of each of the two threaded sliders, two movable limiting plates fixedly connected to the upper surface of the two sets of movable plates, a support cover fixedly connected to one side of the support base, a push rod fixedly installed on the inner wall of the support cover, a positioning clamp plate installed on the telescopic end of the push rod, and the positioning clamp plate located on one side of the positioning plate.

[0008] Preferably, a circular hole is provided on one side of the support base, and a slide rod is slidably connected to the inner wall of the circular hole. One end of the slide rod is fixedly connected to one side of the positioning clamp.

[0009] Preferably, the pressure application component includes a support top plate fixedly installed on the upper surface of the support base, a hydraulic rod fixedly installed on the upper surface of the support top plate, an installation plate fixedly installed on the telescopic end of the hydraulic rod, a pressure plate fixedly installed on the bottom surface of the installation plate, two sliding holes opened on the upper surface of the support top plate, sliding plates slidably connected to the inner walls of the two sliding holes, and the sides of the two sliding plates that are close to each other are fixedly connected to the outer surface of the installation plate.

[0010] Preferably, the upper surface of the workbench is provided with two sets of transmission holes, and the outer surfaces of the two sets of movable plates are slidably connected to the inner walls of the two sets of transmission holes respectively.

[0011] Preferably, a first elastic pad is fixedly connected to one side of each of the two movable limiting plates that are close to each other, and a second elastic pad is fixedly connected to one side of each of the positioning plate and the positioning clamp that are close to each other.

[0012] Preferably, two bearing seats are fixedly installed on the inner wall of the transmission seat, and the inner rings of the two bearing seats are fixedly connected to the outer surface of the positive and negative lead screws.

[0013] Preferably, both ends of the positive and negative lead screws are fixedly connected to rotating handles, and the bottom surface of the worktable is fixedly connected to two sets of support bases.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this wood veneer press places the board above the worktable, allowing it to be initially positioned after contact with the positioning plate. Furthermore, by utilizing the rotation of the positive and negative lead screws and the threaded engagement of the threaded slider, the distance between the two moving limit plates along the transmission hole can be adjusted. Regardless of the difference in board width, the distance between the moving limit plates can be adjusted to ensure a close fit with the board edge. This avoids problems such as insufficient contact area and unstable positioning caused by the limited bevel adaptation range of traditional equipment. The machine can handle multi-specification processing needs, from narrow, thin boards to wide, thick boards, enhancing the flexibility of veneer positioning.

[0016] Compared with existing technologies, this wood veneer press can form a preliminary positioning frame by setting up a movable limiting plate and a positioning plate. In addition, the movement of the positioning clamping plate driven by the push rod can achieve lateral clamping, ensuring the stability of the positioning and alignment of the board and the veneer material, which facilitates subsequent pressure application. The hydraulic rod drives the pressure plate to descend, and with the guiding action of the mounting plate and the sliding plate, the pressure can be evenly applied to the entire veneer surface, reducing defects such as bubbles and warping. Therefore, this veneer press also eliminates the cumbersome steps of changing the adjustment block in traditional equipment, shortens the changeover time for different specifications of boards, and improves the production efficiency of processing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] As attached Figures 1-5 The veneer press for wood processing shown includes a worktable 1. A support base 2 is fixedly connected to one side of the worktable 1. A pressure application component 3 is fixedly installed on the upper surface of the support base 2. A positioning plate 4 is fixedly installed on the upper surface of the worktable 1. A transmission base 5 is fixedly installed on the bottom surface of the worktable 1. Two bearing rings 6 are fixedly embedded in the inner wall of the transmission base 5. The inner rings of the two bearing rings 6 are fixedly connected to a positive and negative lead screw 7. Two threaded sliders 8 are threadedly connected to the outer surface of the positive and negative lead screws 7. Two moving plates 9 are fixedly connected to the outer surface of each of the two threaded sliders 8. Two moving limit plates 11 are fixedly connected to the upper surface of the two sets of moving plates 9. A support cover 13 is fixedly connected to one side of the support base 2. A push rod 14 is fixedly installed on the inner wall of the support cover 13. A positioning clamp 15 is installed on the telescopic end of the push rod 14. A pressure sensor, such as a diaphragm pressure sensor, is set inside the positioning clamp 15. The pressure sensor and the push rod 14 are connected to the control system through a signal line. The positioning clamp 15 is located on one side of the positioning plate 4.

[0025] As can be seen from the above description, this utility model has the following beneficial effects: by placing the plate above the workbench 1, it can be initially positioned after contacting the positioning plate 4. In addition, by utilizing the rotation of the positive and negative lead screws 7 and the threaded engagement of the threaded slider 8, the distance between the two moving limit plates 11 along the transmission hole 10 can be adjusted. No matter how large the difference in the width of the plate is, the distance between the moving limit plates 11 can be adjusted to make it fit the edge of the plate, thus avoiding the problems of insufficient contact area and unstable positioning caused by insufficient adaptation range of the inclined side in traditional equipment. Example

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0027] like Figures 1-5As shown, in a preferred embodiment, a circular hole 17 is provided on one side of the support base 2. A slide rod 18 is slidably connected to the inner wall of the circular hole 17. One end of the slide rod 18 is fixedly connected to one side of the positioning clamping plate 15. Two sets of transmission holes 10 are provided on the upper surface of the worktable plate 1. The outer surfaces of the two sets of moving plates 9 are slidably connected to the inner walls of the two sets of transmission holes 10 respectively. The cooperation between the circular hole 17 and the slide rod 18, and between the transmission holes 10 and the moving plates 9, provides guidance for positioning adjustment. When the push rod 14 drives the positioning clamping plate 15 to move, the slide rod 18 slides along the circular hole 17, preventing the positioning clamping plate 15 from shifting due to force, ensuring the linear accuracy of lateral positioning. The moving plates 9 slide within the transmission holes 10, limiting the tendency of the threaded slider 8 to rotate with the positive and negative screws 7, allowing the moving limit plates 11 to only perform horizontal spacing adjustment, improving the stability of width positioning. The two moving limit plates 11 move closer to each other. One side of each plate is fixedly connected to a first elastic pad 12. The sides of the positioning plate 4 and the positioning clamping plate 15 that are close to each other are fixedly connected to a second elastic pad 16. Two bearing seats 19 are fixedly installed on the inner wall of the transmission seat 5. The inner rings of the two bearing seats 19 are fixedly connected to the outer surface of the positive and negative lead screws 7. Rotary handles 20 are fixedly connected to both ends of the positive and negative lead screws 7. Two sets of support bases 21 are fixedly connected to the bottom surface of the worktable 1. Furthermore, through the first elastic pad 12 and the second elastic pad 16, positioning protection and fit compensation are achieved. When in contact with the board, it can not only buffer the positioning pressure to avoid damage to the edge of the board, but also fill the small defects on the surface of the board through its own deformation, thereby enhancing the tightness of the fit. The bearing seats 19 can assist the bearing rings 6 in supporting the positive and negative lead screws 7 and reduce the shaking during rotation. The rotary handles 20 facilitate the rotation adjustment, while the support bases 21 can stably support the worktable 1.

[0028] like Figures 1-5 As shown, in a preferred embodiment, the pressure application component 3 includes a support top plate 301 fixedly installed on the upper surface of the support base 2. A hydraulic rod 302 is fixedly installed on the upper surface of the support top plate 301. The hydraulic rod 302 needs to be connected to an external oil supply system and control system. An installation plate 303 is fixedly installed on the telescopic end of the hydraulic rod 302. A pressure plate 304 is fixedly installed on the bottom surface of the installation plate 303. Two sliding holes 305 are opened on the upper surface of the support top plate 301. Slide plates 306 are slidably connected to the inner walls of the two sliding holes 305. The sides of the two slide plates 306 that are close to each other are fixedly connected to the outer surface of the installation plate 303. Furthermore, when the hydraulic rod 302 extends and retracts, the installation plate 303 can drive the pressure plate 304 to rise and fall vertically, while the slide plates 306 slide synchronously along the sliding holes 305, which counteracts the eccentric torque when the pressure plate 304 descends, ensuring that the pressure acts vertically on the surface of the board. This allows the bonding material and the substrate to be stressed evenly on the entire contact surface, reducing defects such as bubbles and incomplete bonding, and improving the bonding quality.

[0029] The working process of this utility model is as follows:

[0030] When using this wood veneer press, first place the board and veneer material on the workbench 1 and make contact with one side of the positioning plate 4. Then, the operator can rotate either of the rotating handles 20 at both ends of the positive and negative screws 7 to make the positive and negative screws 7 rotate stably. At this time, the two threaded sliders 8 connected by the positive and negative screws 7 move in opposite directions along the axis of the positive and negative screws 7, which can drive the two sets of moving plates 9 to slide in the transmission holes 10 of the workbench 1, thereby driving the two moving limit plates 11 to adjust the spacing synchronously, which can be adapted to the positioning of boards of different widths.

[0031] After the sheet material is initially positioned by the moving limiting plate 11 and the positioning plate 4, the push rod 14 inside the support cover 13 is activated, which can push the positioning clamp 15 closer to the sheet material, so that the second elastic pad 16 can make close contact with the side of the sheet material to complete the final alignment. Then the pressure component 3 works, and extends through the hydraulic rod 302, which can drive the mounting plate 303 and the pressure plate 304 to descend, so that the facing material can be bonded to the substrate under uniform pressure. This is the working process and working principle of the device.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
