Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, specifically to a preform pressing device for multi-layer sheets. Background Technology

[0002] In the process of pressing and integrating multi-layer board blanks to produce finished boards such as plywood and multi-layer solid wood composite boards, the board pressing device is the core equipment for achieving precise stacking and pressure curing of the board blanks.

[0003] However, in the process of assembling multi-layer fixed-size boards, some small and medium-sized production enterprises still generally use manual positioning and stacking. Specifically, it is necessary to use a ruler to align the four edges of the boards to be stacked one by one and measure the protrusion of each side to control the alignment accuracy between layers. This manual operation mode is not only time-consuming and labor-intensive, which greatly restricts the improvement of overall production efficiency, but also the alignment accuracy of the boards is easily affected by the experience of the operators. Therefore, we propose a new type of assembly and pressing device for multi-layer boards. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a preform pressing device for multilayer boards, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a preform pressing device for multi-layer boards, comprising a worktable and horizontal rod limiting grooves and vertical rod limiting grooves symmetrically opened on the worktable, wherein a positioning structure is provided on the worktable, and the positioning structure includes a horizontal positioning component and a vertical positioning component.

[0006] The horizontal alignment assembly includes a horizontal alignment rod that passes through the limiting groove of the horizontal rod section, a horizontal alignment roller that is rotatably connected to the horizontal alignment rod, two horizontal alignment rods that are fixedly connected by a horizontal connecting rod, a horizontal ball screw block that is fixedly installed at one end of the horizontal connecting rod, a horizontal adjustment motor that is fixedly installed at the bottom of the worktable, and a horizontal adjustment screw rod that is threadedly connected to the horizontal ball screw block that is fixedly installed at the output end of the horizontal adjustment motor.

[0007] The vertical alignment assembly includes a vertical alignment rod that passes through the vertical rod limiting groove. A vertical alignment roller is rotatably connected to the vertical alignment rod. Two vertical alignment rods are fixedly connected by a vertical connecting rod. A vertical ball screw is fixedly installed at one end of the vertical connecting rod. A vertical adjustment motor is also fixedly installed at the bottom of the worktable. A vertical adjustment screw rod that is threadedly connected to the vertical ball screw is fixedly installed at the output end of the vertical adjustment motor.

[0008] Preferably, the vertical connecting rod is located directly below the horizontal connecting rod; guide blocks are fixedly installed at the other end of both the horizontal and vertical connecting rods; two guide rods are fixedly installed at the bottom of the workbench through mounting components, wherein the two guide rods are vertically distributed, and the guide blocks correspond one-to-one with the guide rods and are slidably connected.

[0009] Preferably, the ends of the horizontal adjustment screw rod and the vertical adjustment screw rod are provided with mounting parts that are fixedly connected to the worktable, and the mounting parts are rotatably connected to the horizontal adjustment screw rod and the vertical adjustment screw rod.

[0010] Preferably, there are two horizontal and two vertical alignment rollers, symmetrically distributed on both sides of the worktable. The bottoms of the horizontal and vertical alignment rollers are in contact with the worktable but do not affect their rotation and movement.

[0011] Preferably, the top of the workbench is provided with a bottom pressure plate mounting groove, and a bottom pressure plate adapted to the bottom pressure plate mounting groove is fixedly installed inside the bottom pressure plate mounting groove, and the upper surface of the bottom pressure plate is flush with the upper surface of the workbench.

[0012] Preferably, a gantry frame is fixedly installed on the top of the workbench, a hydraulic rod is fixedly installed on the gantry frame, and a top pressure plate is fixedly installed at the output end of the hydraulic rod.

[0013] Preferably, both the bottom pressure plate and the top pressure plate are fixedly installed with a number of heating strips evenly distributed along the length of the bottom pressure plate and the top pressure plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By setting up a alignment structure driven by horizontal and vertical alignment motors, along with matching horizontal and vertical alignment rollers, screw rods, connecting rods, and other components, the slab blanks are automatically and accurately aligned, eliminating the need for manual alignment with a ruler. This effectively solves the core problems of traditional manual operation being time-consuming and labor-intensive, and alignment accuracy being affected by the operator's experience. It saves manpower and time, improves production efficiency, and ensures consistent alignment between layers. At the same time, the movable horizontal and vertical alignment rollers can directly grind and clean the glue overflowing from the sides of the slab blanks after pressing, without additional manual processing, further optimizing the production process and improving operational efficiency.

[0023] This invention provides a technical solution:

[0024] Please see Figures 1-4 A preform pressing device for multi-layer boards includes a worktable 1 and horizontal rod limiting grooves 2 and vertical rod limiting grooves 3 symmetrically opened on the worktable 1. A positioning structure 4 is provided on the worktable 1, which includes a horizontal positioning component and a vertical positioning component.

[0025] The horizontal alignment assembly includes a horizontal alignment rod 41 that passes through the horizontal rod limiting groove 2, a horizontal alignment roller 42 that is rotatably connected to the horizontal alignment rod 41, two horizontal alignment rods 41 that are fixedly connected by a horizontal connecting rod 43, a horizontal ball screw block 44 that is fixedly installed at one end of the horizontal connecting rod 43, a horizontal adjustment motor 45 that is fixedly installed at the bottom of the worktable 1, and a horizontal adjustment screw rod 46 that is threadedly connected to the horizontal ball screw block 44 that is fixedly installed at the output end of the horizontal adjustment motor 45.

[0026] The vertical alignment assembly includes a vertical alignment rod 47 that passes through the vertical rod limiting groove 3. A vertical alignment roller 48 is rotatably connected to the vertical alignment rod 47. The two vertical alignment rods 47 are fixedly connected by a vertical connecting rod 49. A vertical ball screw block 410 is fixedly installed at one end of the vertical connecting rod 49. A vertical adjustment motor 411 is also fixedly installed at the bottom of the worktable 1. A vertical adjustment screw rod 412 that is threadedly connected to the vertical ball screw block 410 is fixedly installed at the output end of the vertical adjustment motor 411.

[0027] The horizontal adjustment motor 45 starts, driving the horizontal adjustment screw rod 46 to rotate. Through the threaded engagement with the horizontal ball screw block 44, it pulls the horizontal connecting rod 43 and the horizontal alignment rod 41 to move along the horizontal rod limiting groove 2. The vertical adjustment motor 411 starts, driving the vertical adjustment screw rod 412 to rotate. Through the threaded engagement with the vertical ball screw block 410, it pulls the vertical connecting rod 49 and the vertical alignment rod 47 to move along the vertical rod limiting groove 3, so that the horizontal alignment roller 42 and the vertical alignment roller 48 are precisely positioned. Its function is to realize the automatic and precise alignment of the board blank, ensure the consistency of interlayer alignment, and after pressing, the roller rotation can also clean the excess glue on the side of the board blank, eliminating the need for manual alignment of each side and improving production efficiency.

[0028] In some embodiments, the vertical connecting rod 49 is located directly below the horizontal connecting rod 43; guide blocks are fixedly installed at the other ends of both the horizontal connecting rod 43 and the vertical connecting rod 49; two guide rods are fixedly installed at the bottom of the workbench 1 by means of mounting components, wherein the two guide rods are vertically distributed, and the guide blocks correspond one-to-one with the guide rods and are slidably connected.

[0029] In this embodiment, when the horizontal adjustment motor 45 drives the horizontal alignment component to move, the guide block at the other end of the horizontal connecting rod 43 slides along the corresponding guide rod at the bottom of the worktable 1. When the vertical adjustment motor 411 drives the vertical alignment component to move, the guide block at the other end of the vertical connecting rod 49 located directly below the horizontal connecting rod 43 slides along another vertically distributed guide rod. Its function is to provide precise guidance for the movement of the horizontal and vertical alignment components, ensuring smooth movement without deviation, thereby ensuring the alignment accuracy of the horizontal alignment roller 42 and the vertical alignment roller 48 and the subsequent overflow adhesive cleaning effect.

[0030] In some embodiments, the ends of the horizontal adjustment screw rod 46 and the vertical adjustment screw rod 412 are provided with mounting parts that are fixedly connected to the worktable 1, and the mounting parts are rotatably connected to the horizontal adjustment screw rod 46 and the vertical adjustment screw rod 412.

[0031] In this embodiment, when the horizontal adjustment motor 45 drives the horizontal adjustment screw rod 46 to rotate and the vertical adjustment motor 411 drives the vertical adjustment screw rod 412 to rotate, the mounting parts (composed of a bent rod and a collar, which are fixedly connected to the worktable 1 at their ends) provide stable support for the screw rods without affecting their rotation. Their function is to ensure the stability and accuracy of the horizontal adjustment screw rod 46 and the vertical adjustment screw rod 412 when they rotate, thereby ensuring that the horizontal and vertical alignment components can move smoothly, providing a reliable guarantee for the accurate alignment of the board blank and subsequent cleaning of excess glue.

[0032] In some embodiments, there are two horizontal alignment rollers 42 and two vertical alignment rollers 48, which are symmetrically distributed on both sides of the worktable 1. The bottoms of the horizontal alignment rollers 42 and the vertical alignment rollers 48 are in contact with the worktable 1 but do not affect their rotation and movement.

[0033] When the horizontal positioning motor 45 and the vertical positioning motor 411 drive the corresponding alignment components to move, the two horizontal alignment rollers 42 and the vertical alignment rollers 48, which are symmetrically distributed on both sides of the worktable 1, contact the worktable 1 at their bottom and can rotate and move smoothly, fitting the edge of the board blank to complete automatic alignment. After pressing, they can also move slowly along the limiting groove; achieving bidirectional precise positioning of the board blank in both horizontal and vertical directions, ensuring consistent alignment between layers.

[0034] Please see Figure 3 The top of the workbench 1 is provided with a bottom pressure plate mounting groove, and a bottom pressure plate 5 that is adapted to the bottom pressure plate mounting groove is fixedly installed inside the bottom pressure plate mounting groove. The upper surface of the bottom pressure plate 5 is flush with the upper surface of the workbench 1.

[0035] After the board blank is precisely aligned by the alignment structure 4, it naturally falls onto the bottom pressure plate 5 in the mounting groove of the bottom pressure plate at the top of the workbench 1. Because the bottom pressure plate 5 is compatible with the mounting groove and its upper surface is flush with the workbench 1, the board blank can be placed stably and securely. Its function is to provide a flat and stable support base for the board blank, and to cooperate with the top pressure plate 8 to ensure that the board blank is subjected to uniform force during pressing, avoiding pressing deviations caused by uneven support surfaces. At the same time, the stable placement can further ensure the alignment accuracy between layers and help improve the pressing quality.

[0036] Please see Figure 1 and Figure 3 A gantry frame 6 is fixedly installed on the top of the workbench 1. A hydraulic rod 7 is fixedly installed on the gantry frame 6. A top pressure plate 8 is fixedly installed at the output end of the hydraulic rod 7. The bottom pressure plate 5 and the top pressure plate 8 are completely identical in shape and size and are set up correspondingly at the top and bottom.

[0037] After the blank is precisely aligned by the alignment structure 4, it is placed on the bottom pressure plate 5. The gantry frame 6 at the top of the workbench 1 provides stable installation support for the hydraulic rod 7. After the hydraulic rod 7 is started, it drives the top pressure plate 8 at its output end to move down at a uniform speed. Since the top pressure plate 8 and the bottom pressure plate 5 are completely identical in shape and size and correspond vertically, they can accurately fit the blank for pressure application. This achieves pressure curing and molding of the blank. In conjunction with the bottom pressure plate 5, it ensures that the blank is subjected to uniform force and avoids pressing deviation. Combined with the alignment structure 4, it further improves the pressing quality, replaces the traditional manual pressure operation, saves manpower and improves production efficiency.

[0038] In some embodiments, a plurality of heating strips are fixedly installed inside the bottom pressure plate 5 and the top pressure plate 8, which are evenly distributed along the length direction of the bottom pressure plate 5 and the top pressure plate 8.

[0039] In this embodiment, when the hydraulic rod 7 drives the top pressure plate 8 to press the aligned board blank towards the bottom pressure plate 5, the heating strips evenly distributed along their length inside the bottom pressure plate 5 and the top pressure plate 8 heat up synchronously, so that the board blank is heated evenly during the pressing process; this promotes the rapid curing of the adhesive on the bonding surface of the board blank, ensures the pressing quality and bonding stability, and shortens the curing waiting time.

[0040] In practical use, the working principle of this invention is as follows:

[0041] First, based on the fixed dimensions of the slab blank to be pressed in the factory (the device has been customized to fit these dimensions; the dimensions of the top pressure plate 8 and the bottom pressure plate 5 are completely consistent with the slab blank, and the distance between the horizontal alignment rollers 42 and the vertical alignment rollers 48, regardless of whether they move, always precisely matches the width and length of the slab blank), the horizontal adjustment motor 45 and the vertical adjustment motor 411 are pre-controlled to start. The horizontal adjustment motor 45 drives the horizontal adjustment screw rod 46 to rotate. Since the horizontal adjustment screw rod 46 is threadedly connected to the horizontal ball screw block 44, and the guide block at the other end of the horizontal connecting rod 43 slides against the guide rod at a 90-degree angle to the bottom of the worktable 1, the horizontal ball screw block 44 moves smoothly under the drive of the screw rod, thereby driving the horizontal connecting rod 43 to move synchronously. The three traction horizontal alignment rods 41 and the horizontal alignment rollers 42 rotatably connected to them move precisely to the middle position along the limiting groove 2 of the horizontal rod. At the same time, the vertical adjustment motor 411 drives the vertical adjustment screw rod 412 to rotate. The vertical adjustment screw rod 412 drives the vertical ball screw block 410 threadedly connected to it to move. The vertical ball screw block 410 drives the vertical alignment rod 47 and the vertical alignment rollers 48 to move smoothly to the middle position along the limiting groove 3 of the vertical rod through the vertical connecting rod 49 (located directly below the horizontal connecting rod 43, and the guide block at its other end also slides with the corresponding guide rod to ensure movement stability). At this time, the distance between the two horizontal alignment rollers 42 is exactly equal to the width of the board blank, and the distance between the two vertical alignment rollers 48 is exactly equal to the length of the board blank.

[0042] Subsequently, without manual alignment using a ruler, the assembled board blanks to be pressed are placed directly between the horizontal alignment rollers 42 and 48. Under gravity, the board blanks naturally fall onto the bottom pressure plate 5 at the top of the workbench 1. With the help of the horizontal and vertical alignment rollers 42 and the edge of the board blanks, automatic alignment and interlayer alignment are instantly completed, completely avoiding the precision errors and time consumption caused by manual operation. After the board blanks are aligned, adhesive is evenly applied to the bonding surfaces of the board blanks that require gluing. Then, the hydraulic rod 7 on the gantry 6 is activated, driving the top pressure plate 8 to move downwards at a uniform speed. Since the top pressure plate 8 and the bottom pressure plate 5 are identical in shape and size, and both have evenly distributed heating strips inside, the heating strips heat up synchronously during the pressing process. This ensures that the board blanks are subjected to uniform pressure for tight bonding and promotes rapid curing of the adhesive, improving the pressing quality and efficiency.

[0043] After the pressing operation is completed, excess glue may overflow from the side of the board blank. At this time, the horizontal adjustment motor 45 and the vertical adjustment motor 411 are started again, driving the horizontal alignment roller 42 and the vertical alignment roller 48 to move slowly along the limiting groove. The rotation characteristics of the horizontal alignment roller 42 and the vertical alignment roller 48 are used to evenly grind and clean the overflowing glue, eliminating the need for additional manual handling and further improving the continuity and efficiency of the overall production process. The entire process achieves automated alignment, pressing, and glue overflow handling through the precise coordination of the mechanical structure, which not only significantly saves labor costs and operating time but also ensures the stability of the alignment accuracy between the layers of the board blank, effectively solving the core drawbacks of traditional manual operation.

[0044] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
