Description
Technical Field
[0001] The utility model belongs to the technical field of wood cutting, in particular to a wood cross-cutting machine. Background Art
[0002] Wooden toys refer to toys made of natural materials such as wood, bamboo, or synthetic wood. The existing wood is generally divided into round logs and boards. The processing methods of this wood are divided into semi-automatic cross-cutting wood and automatic cross-cutting wood. The semi-automatic cross-cutting wood generally uses a band saw to cut the wood crosswise, dividing the wood into two sections.
[0003] In the existing technology, the structure of the automatic cross-cutting machine is relatively complex and the cost of use is also high. Therefore, for some small enterprises, the semi-automatic cross-cutting machine is more competitive. Figure 1 As shown, it generally includes a frame, a cutting unit, and a positioning seat. During processing, the worker places the wood to be cut against the positioning seat, and then pushes the wood along the positioning seat toward the cutting unit, and the wood is cut into two sections by the cutting unit; the structure of this semi-automatic cross-cutting machine is basically traditional accessories, and no expensive automated components are used, so the cost of use is low, but the pushing of the wood in the wood cutting process is completely dependent on the worker's experience. Once the wood is not completely aligned with the positioning seat during the pushing process, it will affect the cutting effect of the wood, so it requires a high level of worker ability.

[0033] Example 1
[0034] like Figure 2-Figure 5 As shown, this embodiment provides a wood cross-cutting machine, including a frame 1, a cutting unit, two pusher plates 3, two fixed seats 4, two swing frames 5, a press seat 6, a positioning plate 7,
[0035] In this embodiment, the cutting unit includes a cutting groove 201, a cutting knife 202, and a motor 203. The cutting groove 201 is provided on the frame 1, and the cutting groove 201 passes through the upper and lower surfaces of the frame 1 in the vertical direction. The cutting knife 202 is a circular blade, and the cutting knife 202 is arranged as a whole below the frame 1. The cutting knife 202 partially passes through the cutting groove 201 and extends to the top of the frame 1. The part of the cutting knife 202 located above the frame 1 cuts the wood. The motor 203 provided on the frame 1 is used to drive the cutting knife 202 to rotate, and the cutting knife 202 enters a working state when rotating.
[0036] In this embodiment, two push plates 3 are respectively arranged on both sides of the cutting unit, and the push plates 3 can slide on the frame 1 along the wood processing direction. Specifically, sliding grooves 8 are opened on both sides of the frame 1, and the bottoms of the two push plates 3 are slidably connected in the sliding grooves 8;
[0037] The two fixing seats 4 are respectively arranged at positions far away from each other on the two pushing plates 3;
[0038] One end of the two swing frames 5 is rotatably arranged on the two fixed seats 4 respectively, and the swing frames 5 are rotatably connected to the fixed seats 4 through the rotating shaft 9. A torsion spring (not shown in the figure) is sleeved on the rotating shaft 9, and the two ends of the torsion spring are respectively connected to the fixed seats 4 and the swing frames 5; the pressing seat 6 is arranged at the free end of the swing frame 5, and when the torsion spring is relaxed, the pressing seat 6 is close to the push plate 3, and the torsion spring will be twisted in the process of swinging the swing frame 5 upward, so that the torsion spring accumulates elastic potential energy;
[0039] The positioning plate 7 is arranged on one of the push plates 3, and the positioning plate 7 is located on one side of the fixed seat 4, so as not to interfere with the swing of the swing frame 5 and the contact between the pressing seat 6 and the wood;
[0040] The working principle of this embodiment is as follows: the free ends of the two swing frames 5 are swung upward to leave space for placing the wood and the swing frames 5 are kept above the push plates 3, the two ends of the wood to be cut are placed on the two push plates 3 respectively, the wood is positioned by the positioning plates 7, and then the swing frames 5 are released, and the swing frames 5 are swung downward by the elastic force of the torsion spring, so that the pressing seat 6 contacts the wood and cooperates with the push plates 3 to fix the wood on the push plates 3, thus completing the fixing of the wood. At this time, the cutting unit is started, and the worker manually pushes the push plates 3 to make the wood contact with the cutting unit for cutting. After the cutting, the two sections of wood are fixed on the two push plates 3 respectively. At this time, the two push plates 3 are pushed back to the initial position, and the two pieces of wood are removed respectively to complete the wood cutting operation.
[0041] In this embodiment, when the swing frame 5 is maintained above the push plate 3, the torsion spring is subjected to force and has a tendency to return to its original position. To maintain the swing frame 5 in this state, the worker can always apply force to the swing frame 5 by hand, or other supporting structures can be provided to support the swing frame 5.
[0042] Example 2
[0043] This embodiment provides a wood cross-cutting machine, which, in addition to the technical solutions of the above embodiments, also optimizes the structure of the pressing seat 6;
[0044] See also Figure 4In this embodiment, the transverse cross-section of the pressing seat 6 is triangular, so that the bottom surface of the pressing seat 6 is larger, and wood of different widths can be fixed. When fixing the wood, the pressing seat 6 does not need to have the entire bottom surface in contact with the wood;
[0045] The upper part of the pressing seat 6 is rotatably connected to the free end of the swing frame 5; in this way, for wood of different thicknesses, even if the swing frame 5 is at different swing angles when fixing the wood, the pressing seat 6 can keep the bottom surface in contact with the wood, thereby ensuring the fixing effect of the wood.
[0046] Example 3
[0047] This embodiment provides a wood cross-cutting machine, which, in addition to the technical solutions of the above embodiments, also improves the installation method of the positioning plate 7 on the push plate 3;

[0049] For details, please refer to Figure 6 In this embodiment, an adjusting groove 301 is provided on the push plate 3 provided with a positioning plate 7, and the positioning plate 7 is slidably arranged in the adjusting groove 301 along a direction perpendicular to the wood processing direction, and the positioning plate 7 can only move horizontally in the adjusting groove 301, and cannot move vertically, and a locking block 10 is provided on the positioning plate 7, and a locking hole 11 is provided on the locking block 10 along the vertical direction, and the locking hole 11 is opposite to the adjusting groove 301, and a thread is provided on the inner wall of the locking hole 11, and a locking screw 12 is provided on the locking block 10, and the threaded end of the locking screw 12 is threadedly connected with the locking hole 11 and abuts against the bottom surface of the adjusting groove 301;
[0050] In this embodiment, when the threaded end of the locking screw 12 is tightly against the bottom surface of the adjusting groove 301, the positioning plate 7 can be restricted from sliding in the adjusting groove 301, thereby locking the positioning plate 7 in the current position to ensure stable positioning of the wood; when the cutting width needs to be adjusted, the locking screw 12 is rotated to move it axially so that the threaded end of the locking screw 12 is away from the bottom surface of the adjusting groove 301. At this time, the positioning plate 7 can be slid in the adjusting groove 301. After adjusting the positioning plate 7 to the required position, the locking screw 12 is rotated again to move it axially so that the threaded end of the locking screw 12 is in contact with the bottom surface of the adjusting groove 301, thereby locking the positioning plate 7.
[0051] The embodiments of the utility model are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
