[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] The following is in conjunction with the appendix Figure 1-8This application provides a further detailed description. An embodiment of this application discloses a panel-type board nailing machine, including a machine body 1. The machine body 1 is provided with a support rail 2. Above the support rail 2, along its extension direction, a first loading device 3, a second loading device 4, and a nailing device 5 are sequentially arranged, thus establishing that the first loading device 3 is located at the beginning of the support rail 2, and the nailing device 5 is located at the end of the support rail 2. A moving pushing device 6 is also provided on the support rail 2, moving along the extension direction of the support rail 2. A first board is loaded through the first loading device, causing it to fall onto the support rail 2. The moving pushing device 6 then pushes the first board to the position of the second loading device 4. The second loading device 4 drops a second board onto the support rail 2, placing it on top of the first board. The moving pushing device 6 continues to push the first and second boards to the position of the nailing device 5, where the nailing device 5 performs the nailing operation, nailing the first and second boards together.

[0016] Furthermore, the first loading device 3 is provided with a support plate 310 for supporting the first material. The support plate 310 forms an angle with the upper surface of the support track 2. In this embodiment, the support plate 310 and the upper surface of the support track 2 form an obtuse angle, so that the support plate 310 can both support the first material and guide the first material to slide towards the support track 2 through the inclined plate surface. First limiting plates 301 are provided on both sides of the support plate 310 near the end of the support track 2. The two first limiting plates 301 respectively support the two ends of the first material along the direction perpendicular to the extension of the support track 2. A pushing mechanism 302 is provided above the two first limiting plates 301. The two pushing mechanisms 302 are located on both sides of the support plate 310 perpendicular to the extension direction of the support track 2, that is, on both sides of the width direction of the support track 2. The two pushing mechanisms 302 reciprocate linearly in opposite directions. One of the pushing mechanisms 302 pushes the first plate, causing one end of the first plate to move to the other, thereby releasing the obstruction of the corresponding first limiting plate 301 and allowing one end of the first plate to fall onto the bearing rail 2. Subsequently, the other pushing mechanism 302 pushes the other end of the first plate, causing it to also be pushed away from the obstruction of the corresponding first limiting plate 301 and fall onto the bearing rail 2, ultimately achieving the complete placement of the first plate onto the bearing rail 2. To achieve this effect, in this embodiment, the bearing plate surface 310 is also provided with two guide plates 303. The distance between the two guide plates 303 is less than the width of the bearing plate surface 310 along the extension direction of the bearing rail 2, and the first plate is placed between the two guide plates 303. Furthermore, there are gaps between the ends of the two guide plates 303 and the two limiting plates, so that when the first plate comes into contact with the limiting plates and is blocked by the limiting plates, the first plate is exactly located in the gap between the two guide plates 303 and the two limiting plates. By pushing the pusher mechanism 302, one end of the first plate material first passes through the guide plate 303 and moves towards the edge of the bearing plate surface 310 along the width direction of the bearing track 2. This causes the end that was originally blocked by the limiting plate to be no longer blocked after being pushed and translated by the pusher mechanism 302, thus falling downwards onto the bearing track 2. The other end of the first plate material, which was originally close to the edge of the bearing plate surface 310, is then pushed back by another pusher mechanism 302 and also falls onto the bearing track 2.

[0017] Furthermore, since the width direction of the extending direction of the bearing track 2 is the length direction of the No. 1 material, in order to accommodate No. 1 materials of different lengths, two guide plates 303 can be movably connected to the bearing plate surface 310. By changing the distance between the two guide plates 303, the bearing plate surface can be adapted to different lengths of No. 1 materials. However, at this time, the two corresponding limiting plates and the pushing mechanism 302 corresponding to the limiting plates also need to be movable and adjustable. Therefore, in this embodiment, the bearing plate surface 310 is divided into two plates along the width direction of the extending direction of the bearing track 2. Specifically, the first loading device 3 includes a first loading bracket 304. Both ends of the first loading bracket 304 are set on both sides of the extending direction of the bearing track 2 and connected to the machine body 1. The first loading bracket 304 is provided with a connecting rod 305. The extending direction of the connecting rod 305 is perpendicular to the extending direction of the bearing track 2. The bearing plate surface 310 includes a first plate surface 311 and a second plate surface 312. The first plate surface 311 and the second plate surface 312 are slidably connected to the connecting rod 305 through a connecting structure. Since the first plate surface 311 and the second plate surface 312 are improvements based on the bearing plate surface 310, they are coplanar. Furthermore, in this case, the original limiting plates and pushing mechanisms 302 no longer need separate adjustments; they only need to change with the change in the distance between the first plate surface 311 and the second plate surface 312. To fix the position of the first plate surface 311 and the second plate surface 312 relative to the first loading bracket 304, locking structures are provided at the connection points between the first plate surface 311 and the second plate surface 312 and the first loading bracket 304. The locking mechanism employs conventional existing technology. For example, in this embodiment, the locking mechanism uses a fixing ring, which is a ring structure composed of two semi-annular structures joined together. Both semi-annular structures have threaded holes. After clamping the first loading bracket 304 with the two semi-annular structures, a screw is inserted into the threaded holes of the two annular structures. By rotating the screw, the two semi-annular structures move in opposite directions to clamp the first loading bracket 304, thereby fixing the entire fixing ring in a specific position. Simultaneously, the connection structure where the first plate surface 311 and the second plate surface 312 are slidably connected to the first loading bracket 304 can be a sleeve fitted over the first loading bracket 304 with a clearance fit, or similar existing technologies. As long as fixing rings are provided on both sides of the sleeve, the movement of the sleeve can be restricted, thereby fixing the corresponding first plate surface 311 and second plate surface 312. Alternatively, the connection structure where the first plate surface 311 and the second plate surface 312 are slidably connected to the first loading bracket 304 is itself a structure similar to a fixing ring.Meanwhile, based on the improved design of the bearing plate 310, which is split into a first plate 311 and a second plate 312 and slidably connected to the first loading bracket 304, if the locking mechanism is a connecting structure extending from the first plate 311 and the second plate 312, it can achieve a fixing effect when locked, ensuring that both the first plate 311 and the second plate 312 are positioned at an obtuse angle to the upper surface of the bearing track 2. If the locking mechanism is an external additional structure, the sliding connection between the first plate 311 and the second plate 312 and the first loading bracket 304 may not be able to fix the angle. In this case, an auxiliary loading bracket 306 parallel to the first loading bracket 304 can be set. Both the first plate 311 and the second plate 312 are provided with a connecting structure that slidably connects to the auxiliary loading bracket 306, thus helping the first plate 311 and the second plate 312 maintain an obtuse angle with the upper surface of the bearing track 2.

[0018] Furthermore, the second loading device 4 includes two parallel second main supports 401, each perpendicular to the extension direction of the bearing rail 2. Each end of the two second main supports 401 has two support frames 402 supported on the ground. The distance between the two support frames 402 corresponding to each second main support 401 is greater than the width of the bearing rail 2. Between the two second main supports 401 is a second limiting plate 403 parallel to the extension direction of the bearing rail 2, with the surface of the second limiting plate 403 perpendicular to the upper surface of the bearing rail 2. The two second limiting plates 403 form a group. Each group of two second limiting plates 403 has folded edges 404 at both ends along the extension direction of the bearing rail 2, folded in opposite directions. The folded edges 404 can be formed by directly bending the second limiting plates 403, or by connecting external auxiliary plates to form the folded edge 404 structure. Each of the two limiting plates in each set of second limiting plates 403 has a second supporting plate 405 extending in opposite directions near the bottom of the supporting rail 2. This supports the second plate and prevents it from falling directly onto the supporting rail 2. A gap is provided between the end of the folded edge 404 near the second supporting plate 405 and the second supporting plate 405, allowing the second plate to be moved out of the second loading device 4 through the gap. The two limiting plates in each set of second limiting plates 403 and the corresponding folded edge 404 together form an enclosing space. The second plate is placed from above the enclosing space, falls onto the second supporting plate 405 and is supported. By pushing the second plate through the gap between the folded edge 404 and the second supporting plate 405, the second plate is moved out of the gap. With the assistance of the moving pushing device, the second plate falls above the first plate.

[0019] Furthermore, the mobile pushing device 6 includes two pairs of rotating wheels 601, each pair of rotating wheels 601 being connected to a conveyor chain 602. The moving direction of the two conveyor chains 602 is parallel to the extension direction of the carrying track 2. The two conveyor chains 602 are located on the outside of both sides of the extension direction of the conveyor track, that is, the two conveyor chains 602 are symmetrically arranged on both sides of the extension direction of the carrying track 2. The two conveyor chains 602 are connected to a push block 603. Specifically, both conveyor chains 602 are connected to a connecting part 605, which has a connecting hole. The push block 603 has a corresponding connecting hole. The push block 603 is connected to the connecting part 605 of the conveyor chain 602 by bolts passing through the two connecting holes. Then, nuts are provided to lock the push block 603 and the connecting part 605 of the conveyor chain 602 together with the bolts. The pusher block 603 is located above the support rail 2. The pushing surface of the pusher block 603 is perpendicular to the extension direction of the support rail 2, ensuring that the pushing surface of the pusher block 603 can push neatly in the width direction along the extension direction of the conveyor rail. A top block 604 is provided above the pusher block 603. The number of top blocks 604 corresponds to the number of groups of second limiting plates 403, so that the second plate in each group of second limiting plates 403 can be pushed out by the top block 604. The position of the top block 604 corresponds to the gap position between the two second support plates 405 in the corresponding group of second limiting plates 403. When the pusher block 603 moves to the bottom of the second loading device 4, the top block 604 pushes the second plate to move, passing through the gap between the two second support plates 405, and pushes the second plate out of the second loading device 4. Simultaneously, because push block 603 also pushes plate number one, when push block 603 passes the second loading device 4, plate number one is exactly below plate number two. With push block 603 pushing plate number one and top block 604 simultaneously pushing plate number two, when push block 603 passes the second loading device 4, plate number two lands exactly above plate number one. The height of top block 604 is lower than the bottom height of the folded edge 404 in the corresponding set of second limiting plates 403, preventing the folded edge 404 from obstructing the passage of top block 604.

[0020] Furthermore, to facilitate simultaneous control of the two conveyor chains 602 and ultimately ensure balanced movement of the pusher block 603, the drive wheels of the two pairs of rotating wheels 601 are coaxially arranged and connected to the same motor. To maximize the utilization of the track, the distance between the two rotating wheels 601 in each pair is greater than the distance between the first loading device 3 and the nailing device 5, thereby allowing the length of the pusher block 603 to cover the entire width of the supporting track 2.

[0021] Furthermore, the No. 1 sheet material needs to pass under the second loading device 4. To accommodate No. 1 sheets of different thicknesses, the support frame 402 in the second loading device 4 is a telescopic rod. The height of the second loading device 4 is changed by extending and retracting the telescopic rod, thereby changing the distance between the second loading device 4 and the supporting track 2. The telescopic rod can be driven by conventional existing technologies such as manual, electric, hydraulic, or pneumatic. In this embodiment, a cylinder drive is used.

[0022] Furthermore, since there is a distance between the second loading device 4 and the nailing device 5, and there is no restraint after the second board falls above the first board, it may dislocate during movement. To limit the position of the second board, an adjustment device 7 is also included above the support rail 2. The adjustment device 7 is located between the nailing machine and the second loading device 4. The adjustment device 7 includes an adjustment plate 701 parallel to the extension direction of the support rail 2. The surface of the adjustment plate 701 is perpendicular to the upper surface of the support rail 2. Two adjustment plates 701 form a group, and each group of adjustment plates 701 corresponds to a group of second limiting plates 403. Thus, the number of adjustment plates 701 is equal to the number of groups of second limiting plates 403. The distance between two adjustment plates 701 in a group corresponds to the distance between two second limiting plates 403 in the corresponding group, so that after the second board leaves the second loading device 4, it enters the limiting range of the corresponding group of adjustment plates 701. Therefore, during the movement of the second board, its position is always limited by the surface of the corresponding group of adjustment plates 701 in the opposite direction. Furthermore, the adjusting plate 701 is designed to restrict plate number two, not plate number one. Therefore, the bottom height of the adjusting plate 701 near the bearing rail 2 should be higher than the height of plate number one relative to the bearing rail 2, which is the thickness of plate number one. Thus, a suitable adjusting plate 701 can be replaced to accommodate plate number one of different thicknesses, or a retractable support structure can be installed, similar to the second loading device 4, to change the distance between the bottom of the adjusting plate 701 and the upper surface of the bearing rail 2 through extension and retraction.

[0023] Furthermore, the nailing device 5 is a conventional nailing machine, connected to the machine body 1. Besides the second loading device 4 being directly supported on the ground via the support frame 402, the first loading device 3, adjustment device 7, and moving pushing device 6 can also be independent of the machine body 1. In this embodiment, the first loading device 3, adjustment device 7, and moving pushing device 6 are all connected to the machine body 1. The reason the second loading device 4 is directly supported on the ground is because there is a distance between the first loading device 3 and the nailing device 5. Depending on actual needs, the second loading device 4 may move within this distance range. For ease of maintenance and cost considerations, no further sliding connection structure or similar moving structure is provided to allow the second loading device 4 to move relative to the machine body 1. If necessary, personnel can set it as needed based on the actual situation and existing technology.

[0024] Furthermore, the pushing mechanism 302 includes a pushing block and a pushing block driving device. The pushing block is positioned at the thickness angle of the No. 1 plate. It is necessary to ensure that the corresponding thickness of the pushing block is not greater than the thickness of the No. 1 plate, so that the pushing block 603 can only push one No. 1 plate at a time, preventing the pushing block from pushing multiple No. 1 plates at once and causing program chaos. The pushing block driving device uses a conventional driving device with telescopic function. For example, in this embodiment, the pushing block driving device is a cylinder. The bearing plate surface 310 or the first plate surface 311 and the second plate surface 312 are provided with special connecting parts to connect the fixed end of the cylinder. The telescopic end of the cylinder is connected to the pushing block. Through the extension and retraction of the telescopic end of the cylinder, the pushing block moves linearly back and forth.

[0025] Working Principle: Taking rectangular plates No. 1 and No. 2 as an example, multiple No. 1 plates are loaded into the first loading device 3, and multiple No. 2 plates are loaded into the second loading device 4. The length direction of No. 1 plate is perpendicular to the extension direction of the bearing rail 2. One side of No. 1 plate is in contact with the bearing plate surface 310. Under the action of its own weight and the guidance of the inclined bearing plate surface 310, No. 1 plate falls towards the bearing rail 2 until it is supported by two first limiting plates 301. The length direction of No. 2 plate is the same as the extension direction of the bearing rail 2. Under the restriction of the second limiting plate 403, it falls vertically towards the bearing rail 2 until it is supported by the second bearing plate 405. The pushing mechanism 302 on one side of the first loading device 3 pushes one end of No. 1 plate down, and then the pushing mechanism 302 on the other side pushes the other end of No. 1 plate down, so that the entire No. 1 plate falls onto the bearing rail 2. The moving pushing device 6 is activated, so that the pushing block 603 pushes No. 1 plate towards the second loading device 4. When board number one moves to the bottom of the second loading device 4, the top block 604 on push block 603 contacts board number two. Push block 603 continues to move forward. At the same time, while push block 603 pushes board number one forward, the top block 604 on push block 603 simultaneously pushes board number two forward. When board number two is completely detached from the second loading device 4, board number two lands directly above board number one, forming a cross-shaped arrangement. Push block 603 continues to push board number one and board number two to the position of nailing device 5. Nailing device 5 performs a nailing operation, fixing the cross-shaped arrangement of board number one and board number two.

[0026] In the actual workflow, two No. 1 boards are usually paired with at least one No. 2 board and nailed in an I-shape. As needed, more sets of second limiting plates 403 are added to make more No. 2 boards nailed to the two No. 1 boards in a parallel arrangement. Multiple No. 2 boards are nailed into the two No. 1 boards in a fence shape, and finally the designed panel is produced.
