Description

Technical Field

[0001] This utility model relates to the technical field of composite board processing equipment, and in particular to a composite board pressing and molding device. Background Technology

[0002] With increasing environmental awareness, composite boards are being used more and more widely in the furniture manufacturing industry. Composite board splicing technology not only improves wood utilization but also effectively shortens the wood growth cycle. Currently, composite board splicing mainly uses adhesive bonding. After gluing, the blank boards need to be placed on a flat surface for pressing, and subsequent processing can only proceed after the adhesive has fully cured. Traditional pressing processes typically use heavy-load flat pressing, which has many drawbacks: First, the handling and placement of heavy objects requires a lot of manpower, resulting in high labor intensity for operators; second, the pressing area of ​​a single heavy object is limited, leading to low pressing efficiency; third, storing a large number of heavy objects requires a lot of space, increasing production costs. Furthermore, traditional pressing methods make it difficult to press multiple layers of composite boards simultaneously and cannot guarantee uniform stress on each layer, easily leading to unstable pressing quality. These problems seriously restrict the efficiency and quality improvement of composite board production. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a composite board pressing and molding device that can improve pressing efficiency and achieve uniform pressing of multi-layer composite boards.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Please see Figures 1 to 4 As shown, this utility model provides an embodiment: a composite board pressing and molding device, including a support base 1. First telescopic cylinders 2 are arranged around the upper surface of the support base 1. A lifting plate 3 is provided at the end of the telescopic rod of each of the first telescopic cylinders 2. Multiple support rods 4 are evenly spaced at both ends of the upper surface of the support base 1. A fixing plate 41 is provided at the end of each support rod 4. A second telescopic cylinder 42 is embedded in the middle of the fixing plate 41. A pressing plate 4 is provided at the end of the telescopic rod of the second telescopic cylinder 42. 3. Multiple strip-shaped guide grooves 44 are equally spaced on the inner side of the support rod 4. The length of the strip-shaped guide grooves 44 increases sequentially from front to back. Multiple cold-pressing plates 5 are equally spaced between the lifting plate 3 and the pressing plate 43. The front and rear ends of the left and right sides of the cold-pressing plate 5 are sleeved on the support rod 4 through connecting sleeves 51. The left and right sides of the cold-pressing plate 5 are provided with sliders 52 for embedding into the strip-shaped guide grooves 44. The cold-pressing plates 5 are arranged one by one with the strip-shaped guide grooves 44 from top to bottom.

[0015] The support base, serving as the load-bearing platform, can be constructed using a welded steel frame structure, with a positioning reference surface on its surface to ensure component installation accuracy. The first telescopic cylinder, acting as the lifting drive unit, can utilize either a hydraulic or pneumatic actuator, achieving multi-cylinder linkage through a synchronous control system. The support rod, serving as the guide column, can be made of hollow square steel with internal reinforcing ribs to enhance bending strength. The strip guide rail, serving as the positioning reference, can be milled to form a continuous guide surface, with varying lengths to accommodate different floor heights. The cold-press plate, serving as the pressure-applying component, can be made of chrome-plated steel, with rolling elements embedded in the connecting sleeve to reduce frictional resistance. The slider, serving as the guiding component, can be fitted with a PTFE wear-resistant pad, forming a clearance fit with the guide rail.

[0016] Specifically, when the device is in operation, the first telescopic cylinder pushes the lifting plate to a predetermined height, and the operator places the sheets to be pressed layer by layer on the surface of the cold-pressing plate. When the second telescopic cylinder drives the pressing plate to press down, each cold-pressing plate slides along the guide rail groove on the inner side of the support rod. Because the length of the guide rail groove increases layer by layer, the cold-pressing plates of each layer form a stepped distribution in the vertical direction, ensuring that the multiple layers of sheets are pressed simultaneously. The cooperation between the connecting sleeve and the support rod restricts the horizontal displacement of the cold-pressing plate, and the fitting structure between the slider and the guide rail groove ensures that the cold-pressing plate remains horizontal during the pressing process. After pressing is completed, the lifting plate drives the entire cold-pressing plate to descend, making it easy to remove the finished sheet.

[0017] Compared to existing technologies, traditional heavy-duty pressing requires manual stacking of counterweights, while this solution achieves automatic layered pressing through an adjustable cold-pressing plate structure, eliminating manual handling. Conventional single-layer pressing equipment is limited in processing efficiency by the amount of material processed in a single operation, while this device, utilizing a stepped guide rail design, can simultaneously press multiple layers of sheet metal in a single operation. Fixed pressing fixtures require ample space for turnover, while this structure reduces the equipment's footprint through vertical stacking.

[0018] Through the above technical solution, this application realizes continuous pressing operation of composite panels. Operators only need to perform loading and unloading operations to complete the synchronous processing of multi-layer panels. The layered positioning structure of the cold-pressed plate ensures uniform stress on each layer, avoiding the adhesive failure problem caused by uneven pressure distribution in traditional processes. The height-adjustable design of the device facilitates adjustment of the working height to adapt to the processing needs of different panel specifications, while the compact three-dimensional layout effectively optimizes the utilization rate of workshop space.

[0019] Please continue reading. Figure 1 , Figure 3 and Figure 4 As shown in one embodiment of the present invention, a fixing plate 11 is provided in front of the support base 1. Fixing rods 12 are provided at both ends of the upper surface of the fixing plate 11. A dual-output motor 13 is provided in the middle of the fixing plate 11. The output end of the dual-output motor 13 is connected to a steering gear (not shown). The output end of the steering gear is connected to a first screw 14. A strip-shaped groove 15 is provided on the inner side of the fixing rod 12. The first screw 14 is disposed in the strip-shaped groove 15. A moving block 16 is spirally sleeved on the first screw 14. A lifting feeding plate 17 is provided on the inner side of the moving block 16. A pushing member 6 for pushing the plate onto the cold pressing plate 5 is provided on the lifting feeding plate 17.

[0020] Among them, the dual-output motor refers to a power device with bidirectional rotation output function. Specifically, it can be implemented by using a servo motor with a forward and reverse control module, and the power is transmitted to the first screw through the steering gear to achieve bidirectional drive.

[0021] The first screw refers to a transmission rod with a threaded structure, which can be implemented by a trapezoidal threaded rod or a ball screw, and achieves linear displacement through helical engagement with the moving block.

[0022] The lifting feeding plate refers to the planar structure that supports the plates to be pressed. It can be made of aluminum alloy plate or steel plate, and its vertical position can be adjusted by the cooperation of the moving block and the first screw.

[0023] Specifically, the dual-output motor drives two first screws to rotate synchronously via a steering mechanism, causing the moving block to move up and down along the strip groove of the fixed rod. After the lifting feeding plate reaches the set height with the moving block, the pushing component horizontally pushes the sheet material to the working area of ​​the cold-pressing plate. In this process, the rotational motion of the first screws is converted into the linear motion of the lifting feeding plate, so that the sheet material is accurately positioned at the predetermined gap between the multi-layer cold-pressing plates.

[0024] Compared to existing technologies, traditional manual handling requires repeated adjustments to the stacking position of the boards and poses safety hazards. This solution, however, achieves automated feeding through a motor-driven screw mechanism, eliminating the physical exertion of manual handling. Existing single-point feeding devices cannot adapt to the varying gaps between multi-layer cold-pressed boards. This solution, through an adjustable-height lifting feeding plate and pusher components, can accommodate the pressing needs of composite boards with different numbers of layers.

[0025] Through the above technical solution, this application realizes automatic positioning and layered feeding of sheet materials, solving the technical problems of low efficiency and difficulty in accurately aligning multi-layer cold-pressed sheets during manual handling. The height adjustment function of the lifting feeding plate ensures that sheets of different thicknesses can accurately enter the corresponding pressing station, and the horizontal pushing action of the pusher prevents the sheet materials from shifting during the transfer process, significantly improving the automation level of composite board pressing and forming.

[0026] Please continue reading. Figure 1 and Figure 3 As shown, in one embodiment of this utility model, the pushing member 6 includes a pushing plate 61. The lifting feeding plate 17 has strip-shaped guide openings 62 at both its left and right ends. A pushing frame 63 is fitted onto the lifting feeding plate 17. Vertical rods on both sides of the pushing frame 63 pass through the strip-shaped guide openings 62. Fixing blocks 64 are provided at both the front and rear ends of the lower surface of the lifting feeding plate 17. A drive motor 65 is provided on the front fixing block 64. The output end of the drive motor 65 is connected to a second screw 66, which is rotatably connected to the rear fixing block 64 via a bearing. The lower horizontal plate of the pushing frame 63 is spirally fitted onto the second screw 66. A third telescopic cylinder 67 is embedded in the middle of the upper horizontal plate of the pushing frame 63. The pushing plate 61 is located at the end of the telescopic rod of the third telescopic cylinder 67, and the pushing plate 61 is positioned on the upper surface of the lifting feeding plate 17.

[0027] The push frame is a rectangular structure composed of two vertical rods and upper and lower horizontal plates. It can be constructed using welded or bolted metal profiles, with the vertical rods passing through a strip-shaped guide opening to form a sliding limit. The strip-shaped guide opening is an opening extending laterally along the lifting feed plate, which can be machined into a straight groove structure to restrict the push frame to move only horizontally. The second screw is a threaded transmission rod, which can be implemented using a ball screw or trapezoidal screw. It is driven by a drive motor to rotate and drive the push frame to translate. The third telescopic cylinder is an actuator that moves vertically, which can be implemented using a pneumatic cylinder or an electric push rod. It is used to adjust the height difference between the push plate and the lifting feed plate.

[0028] Specifically, after the drive motor starts, it drives the second screw to rotate. Since the lower horizontal plate of the pushing frame is spirally fitted onto the second screw, the pushing frame moves horizontally along the strip guide opening. The telescopic rod of the third telescopic cylinder drives the pushing plate to rise and fall vertically. When the pushing plate descends to contact the material on the lifting feeding plate, the horizontally moving pushing frame pushes the material into the cold pressing plate area. The vertical rod of the pushing frame cooperates with the strip guide opening to form a sliding guide, ensuring the straightness of the pushing trajectory. Simultaneously, the third telescopic cylinder can adjust the height of the pushing plate according to the thickness of the material.

[0029] Compared with existing technologies, traditional blank board pushing relies heavily on manual operation or unidirectional mechanical pushing, resulting in low positioning accuracy and inability to adapt to boards of different thicknesses. This solution achieves automation and high adjustability of board pushing through the coordinated control of screw drive and telescopic cylinder, while the guiding structure of the pushing frame eliminates the risk of offset during the pushing process.

[0030] Through the above technical solution, this application solves the problem of low efficiency and easy misalignment of the boards caused by manual pushing. By combining mechanical transmission and height adjustment, it ensures that boards of different thicknesses can be accurately pushed to the cold pressing area, while reducing the need for manual intervention and improving the continuity and stability of the composite board pressing process.

[0031] Please continue reading. Figure 1 As shown, in one embodiment of the present invention, a plurality of balls (not shown) are embedded at equal intervals on the inner side of the connecting sleeve 51.

[0032] The connecting sleeve is a ring-shaped component fitted around the outside of the support rod. It can be made of metal or high-strength engineering plastic and is used to achieve a sliding connection between the cold-pressed plate and the support rod.

[0033] Among them, the ball refers to the spherical rolling element embedded in the inner side of the connecting sleeve. It can be made of stainless steel or ceramic material. It forms a rolling contact surface by being evenly distributed, which is used to reduce the frictional resistance when the cold-pressed plate moves along the support rod.

[0034] Specifically, the cold-pressing platen is slidably fitted to the support rod via a connecting sleeve, with ball bearings equidistantly embedded in the inner circumference of the connecting sleeve. When the cold-pressing platen moves vertically driven by the lifting platen or pressing platen, the ball bearings and the surface of the support rod generate rolling friction, replacing the traditional sliding friction mode. This structure keeps the movement trajectory of the cold-pressing platen on the support rod stable, avoiding movement jamming caused by excessive friction coefficient.

[0035] Compared to existing technologies, the sliding sleeve of traditional composite plate pressing devices is in direct contact with the support rod. Over long-term use, this can easily lead to wear and deformation due to friction, affecting pressing accuracy. This solution utilizes ball bearing rolling contact, effectively reducing contact surface wear while maintaining structural compactness and extending the device's service life.

[0036] Through the above technical solution, this application solves the problem of poor movement caused by frictional resistance during the movement of cold press plates, ensuring that multi-layer cold press plates can be accurately aligned during the pressing process, and avoiding uneven distribution of pressing pressure caused by movement deviation.

[0037] The drive motor, dual-output motor, and telescopic cylinder in this invention are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0038] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
