[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0035] like Figure 1 and Figure 2 As shown, a nailing device for wooden pallet production is used to limit the position of the beams of the wooden pallet when nailing, comprising:

[0036] Platform 1;

[0037] At least two limiting structures are provided on the platform 1, one of which is used to limit the position of each longitudinal beam 21, and the other is used to limit the position of each transverse beam 22. The limiting structures include:

[0038] Several groups of clamping blocks are arranged opposite to each other, and a limiting space for fixing the beam is formed between each group of clamping blocks;

[0039] An adjustment component for causing each set of clamping blocks to move relative to each other to adjust the size of the limiting space;

[0040] The above technical solution can be used to limit the beams of wooden pallets of different thicknesses. When in use, the longitudinal beam 21 serving as the bottom support is placed between the clamping blocks of one of the limiting knots, and the clamping blocks of the limiting structure are driven to move relative to each other by the adjusting component, and the spacing of the clamping blocks is adjusted to a position that fits the longitudinal beam 21. The crossbeam 22 serving as the top support is placed at the upper end of the longitudinal beam 21, and it is ensured that the crossbeam 22 is located between the clamping blocks of another limiting knot. Then, the clamping blocks of the limiting structure are driven to move relative to each other by the adjusting component, and the spacing of the clamping blocks is adjusted to a position that fits the crossbeam 22. The clamping positioning of the longitudinal beam 21 and the crossbeam 22 can be achieved. Therefore, the position of the clamping blocks can be adjusted to adapt to beams of different thicknesses, thereby preventing gaps between the longitudinal beam 21 and the crossbeam 22 and the clamping blocks during nailing, causing shaking, and improving the accuracy of nailing.

[0041] like Figure 3 As shown, in this embodiment, the limiting structure includes: a first limiting structure for limiting each longitudinal beam 21, the first limiting structure includes: a first clamping block 4 and a first limiting space formed by the first clamping block 4 for fixing the longitudinal beam 21, and a first adjustment component for adjusting the first limiting space; the first adjustment component includes: a first plate 2 with a first slide rail 3, the first clamping block 4 is slidably arranged in the first slide rail 3, and the first plate 2 is connected to the platform 1; a first screw rod 7 rotatably arranged in the first slide rail 3, the first screw rod 7 is matched with a first screw rod groove 5 opened on the surface of the first clamping block 4, and the first screw rod 7 is a multi-section bidirectional screw rod, so as to drive each group of first clamping blocks 4 to move closer to or away from each other through the bidirectional screw rod;

[0042] The above technical solution can be used to adjust the spacing of the first clamping blocks 4 according to the thickness of the longitudinal beam 21. When in use, by rotating the first screw rod 7, the first screw rod 7 can cooperate with the first screw rod groove 5 to drive the first clamping blocks 4 to slide along the first slide rail 3, thereby adjusting the spacing of each group of first clamping blocks 4 to a position consistent with the thickness of the longitudinal beam 21.

[0043] like Figure 4 As shown, in this embodiment, the limiting structure also includes: a second limiting structure for limiting each crossbeam 22, the second limiting structure including: a second clamping block 15 and a second limiting space formed by the second clamping block 15 for fixing the crossbeam 22, and a second adjustment component for adjusting the second limiting space; the second adjustment component includes: a second plate 13 with a second slide rail 14, the second plate 13 is fixedly connected to the first clamping block 4, and the second clamping block 15 is slidably arranged in the second slide rail 14; a second screw rod 18 arranged in the second slide rail 14 is rotated, the second screw rod 18 is matched with a second screw rod groove 16 opened on the surface of the second clamping block 15, and the second screw rod 18 is a multi-section bidirectional screw rod, so as to drive each group of second clamping blocks 15 to move closer to or away from each other through the bidirectional screw rod;

[0044] The above technical solution can be used to adjust the spacing of the second clamping blocks 15 according to the thickness of the beam 22. When in use, by rotating the second screw rod 18, the second screw rod 18 can cooperate with the second screw rod groove 16 to drive the second clamping blocks 15 to slide along the second slide rail 14, thereby adjusting the spacing of each group of second clamping blocks 15 to a position consistent with the thickness of the beam 22.

[0045] like Figure 1 As shown, in this embodiment, two second limiting structures are provided, and the two second limiting structures are symmetrically arranged about the platform 1 to limit the two ends of the cross beam 22 through the second plate 13. A third limiting structure for fixing the two ends of the longitudinal beam 21 is provided on the platform 1;

[0046] The above technical solution can be fully limited, and at the same time, there is no need to clamp the beam through the first clamping block 4 and the second clamping block 15. The function of the first clamping block 4 and the second clamping block 15 is only to limit. When in use, the first adjustment component and the second adjustment component are used to adjust the interval between the first clamping block 4 and the second clamping block 15 respectively to ensure that the spacing of the first clamping block 4 just matches the thickness of the longitudinal beam 21, and the spacing of the second clamping block 15 just matches the thickness of the cross beam 22. When positioning, first align the longitudinal beam 21 with the first limiting space between the first clamping blocks 4 and insert it. The first clamping block 4 limits the two sides of the longitudinal beam 21, and then through the second The three-limiting structure limits the two ends of the longitudinal beam 21, thereby ensuring that the longitudinal beam 21 cannot slide arbitrarily along the platform 1, and the cross beam 22 is placed in the second limiting space between the second clamping blocks 15. The second clamping blocks 15 limit the two sides of the cross beam 22. At the same time, the two second plates 13 limit the two ends of the cross beam 22, thereby ensuring that the cross beam 22 cannot slide along the upper end surface of the longitudinal beam 21, thereby completing the limitation of the longitudinal beam 21 and the cross beam 22. When the longitudinal beam 21 and the cross beam 22 of this specification need to be fixed again in the future, there is no need to adjust the position of the first clamping block 4 and the second clamping block 15 again, and they can be directly placed in, which is more efficient.

[0047] like Figure 1 and Figure 3 As shown, in this embodiment, the third limiting structure includes: two limiting plates symmetrically arranged with respect to the platform 1, the two limiting plates fixing the ends of the longitudinal beam 21, and one limiting plate being movable relative to the other limiting plate; specifically, the third limiting structure also includes: a through groove provided on the surface of the platform 1; a movable limiting plate slidably provided in the through groove; an electric telescopic rod 12 fixedly connected to the base and the platform 1, and a telescopic end of the electric telescopic rod 12 fixedly connected to the movable limiting plate;

[0048] The above technical solution can fix the two ends of the longitudinal beam 21. When the spacing between the first clamping blocks 4 is adjusted, the electric telescopic rod 12 is started to drive the movable limit plate 9 to slide along the through groove on the surface of the platform 1 until the upper end of the movable limit plate 9 is flush with the upper end surface of the platform 1. After the longitudinal beam 21 is inserted between the first clamping blocks 4, ensure that one end of the longitudinal beam 21 is in contact with the fixed limit plate 8. Then, the electric telescopic rod 12 is started to drive the movable limit plate 9 to rise and reset, thereby limiting the two ends of the longitudinal beam 21 through the fixed limit plate 8 and the movable limit plate 9.

[0049] like Figure 3 As shown, in this embodiment, the inner wall of the through groove is provided with a guide protrusion 11, and the guide protrusion 11 is slidably engaged with the guide groove 10 provided on the side of the movable limiting plate 9;

[0050] The adoption of the above technical solution can improve the impact resistance of the movable limiting plate 9. By providing a guide groove 10 on the side of the movable limiting plate 9, on the one hand, it can ensure that when the movable limiting plate 9 slides in the through groove, the guide groove 10 can slide with the guide protrusion 11 to guide the movement of the movable limiting plate 9. At the same time, when the longitudinal beam 21 generates pressure on the movable limiting plate 9, the pressure will not directly act on the electric telescopic rod 12, thereby preventing the electric telescopic rod 12 from bending and deforming.

[0051] like Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, the device further includes:

[0052] A first motor 6 connected to the first plate 2, the output shaft of the first motor 6 being fixedly connected to a first screw rod 7; the first motor 6 being fixedly connected to one of the first screw rods 7 of the first position-limiting structure, the first screw rods 7 of the two first position-limiting structures being each provided with a belt pulley 19, and a belt 20 being provided between the belt pulleys 19;

[0053] A second motor 17 connected to the second plate 13 , wherein the output shaft of the second motor 17 is fixedly connected to the second screw rod 18 ;

[0054] The above technical solution can automatically control the movement of the first clamping block 4 and the second clamping block 15. When the spacing of the first clamping block 4 needs to be adjusted, the first motor 6 is started to drive the first screw rod 7 to rotate, thereby driving the first clamping block 4 to move. Since a belt pulley 19 and a belt 20 are provided between adjacent first screw rods 7, the other first screw rod 7 does not need to be equipped with a first motor 6. When the first motor 6 drives the first screw rod 7 to rotate, the first screw rod 7 can drive the other first screw rod 7 to rotate through the belt pulley 19 and the belt 20. Similarly, when the second motor 17 is working, it can drive the second screw rod 18 to rotate, thereby driving the second clamping block 15 to move.

[0055] like Figure 1 As shown, in this embodiment, a through groove 23 is opened on the surface of the platform 1, and the through groove 23 and the first slide rail 3 are both penetrated;

[0056] The above technical solution can prevent foreign matter from entering the first slide rail 3 and causing the movement of the first clamping block 4 to be blocked.

[0057] Working principle: When in use, the first motor 6 drives the first screw rod 7 to rotate, and the first screw rod 7 can cooperate with the first screw rod groove 5 to drive the first clamping block 4 to slide along the first slide rail 3, thereby adjusting the spacing of each group of first clamping blocks 4 to a position consistent with the thickness of the longitudinal beam 21. The second motor 17 drives the second screw rod 18 to rotate, and the second screw rod 18 can cooperate with the second screw rod groove 16 to drive the second clamping block 15 to slide along the second slide rail 14, thereby adjusting the spacing of each group of second clamping blocks 15 to a position consistent with the thickness of the crossbeam 22.

[0058] When positioning the longitudinal beam 21, first align the longitudinal beam 21 with the first limiting space between the first clamping blocks 4 and insert it. The first clamping blocks 4 limit the two sides of the longitudinal beam 21 to ensure that one end of the longitudinal beam 21 contacts the fixed limiting plate 8. Then, the electric telescopic rod 12 is started to drive the movable limiting plate 9 to rise and slide along the through groove on the surface of the platform 1. In this way, the fixed limiting plate 8 and the movable limiting plate 9 limit the two ends of the longitudinal beam 21 to ensure that the longitudinal beam 21 cannot slide arbitrarily along the platform 1.

[0059] Place the crossbeam 22 into the second limiting space between the second clamps 15. The second clamps 15 limit the two sides of the crossbeam 22. At the same time, the two second plates 13 limit the two ends of the crossbeam 22, thereby ensuring that the crossbeam 22 cannot slide along the upper end surface of the longitudinal beam 21, thereby completing the limitation of the longitudinal beam 21 and the crossbeam 22. When the longitudinal beam 21 and the crossbeam 22 of this specification need to be fixed again in the future, there is no need to adjust the position of the first clamp 4 and the second clamp 15 again. They can be directly placed in, which is more efficient.
