A cylindrical core-removing knife is detachably connected to the end of the clamping seat away from the second motor.

[0005] By adopting the above technical solution, the output shaft of the first motor drives the bidirectional lead screw to rotate, the two sliders move towards each other, and the two clamping blocks move towards each other, which facilitates the clamping of the wood. The output shaft of the second motor drives the clamping seat to rotate, and the core-removing knife rotates accordingly. The piston rod of the hydraulic cylinder drives the slide to move towards the support, which can adjust the distance between the core-removing knife and the wood. The rotating core-removing knife contacts the wood and moves towards the support continuously, which is conducive to core removal. This not only saves manpower but also improves efficiency.

[0006] Specifically, two guide rods are fixed on the side of the slide away from the support, and the stop block is provided with two through holes that are adapted to the guide rods.

[0007] By adopting the above technical solution and setting the guide rod, the stability of the slide can be improved.

[0008] Specifically, each of the two clamping blocks is fixed with multiple conical inserts.

[0011] By adopting the above technical solution, the sawdust generated during the core removal process falls into the collection box, which facilitates the collection of sawdust. The setting of pads, handles and casters makes it easy to transfer the collection box from the base plate to the ground. Lifting the baffle makes it easy to discharge the sawdust in the collection box.

[0012] Specifically, the top of the support is provided with a cover plate.

[0013] By adopting the above technical solution, the cover plate can protect the bidirectional lead screw in the support.

[0014] The beneficial effects of this utility model are:

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 3 , Figure 4As shown, the wood core-removing device of this utility model includes a support plate 1. A support 2 and a stop block 13 are welded and fixed to the top of the support plate 1. A first motor 3 is bolted to one side of the support 2. The output shaft of the first motor 3 is connected to a double-acting screw 30 via a coupling. Two sliders 6 are provided inside the support 2. Each slider 6 has a screw hole adapted to the double-acting screw 30. A crossbar 5 is provided below the double-acting screw 30. Both ends of the crossbar 5 are welded to the support 2. Each slider 6 has a through hole adapted to the crossbar 5. Clamping blocks 7 are detachably connected to the opposing sidewalls of the two sliders 6. The clamping blocks 7 can be connected to the sliders 6 via bolts. Each opposing sidewall of the two clamping blocks 7 has a V-shaped groove. A hydraulic cylinder 12 is bolted to the side of the support 2 away from the 13. A slide 15 is bolted to the piston rod of the hydraulic cylinder 12. A second motor 14 is bolted to the side of the slide 15 away from the support 2. A retainer 16 is detachably connected to the output shaft of the second motor 14. The retainer 16 is bolted to the output shaft of the second motor 14. A bearing seat 18 is bolted to the slide 15. The end of the retainer 16 away from the support 2 is fixed inside the bearing seat 18. The bearing seat 18 is existing technology. The specific connection method between the bearing seat 18 and the retainer 16 will not be described in detail. A cylindrical core-splitting knife 17 is detachably connected to the end of the retainer 16 away from the second motor 14. The core-splitting knife 17 is bolted to the retainer 16.

[0026] In use, the output shaft of the first motor 3 drives the bidirectional lead screw 30 to rotate, the two sliders 6 move towards each other, and the two clamping blocks 7 move towards each other to facilitate the clamping of the wood. The output shaft of the second motor 14 drives the clamping seat 16 to rotate, and the core-removing knife 17 rotates accordingly. The piston rod of the hydraulic cylinder 12 drives the slide 15 to move towards the support 2 (the hydraulic cylinder 12 is existing technology, and its specific principle will not be described in detail). This can adjust the distance between the core-removing knife 17 and the wood. The rotating core-removing knife 17 contacts the wood and continuously moves towards the support 2, which is conducive to core removal. This not only saves manpower but also improves efficiency.

[0027] To improve the stability of the slide 15, for example, such as Figure 1 As shown, two guide rods 11 are welded and fixed on the side of the slide block 15 away from the support 2, and the stop block 13 is provided with two through holes that are adapted to the guide rods 11.

[0028] To improve the stability of wood, for example, such as Figure 2 As shown, multiple conical inserts 70 are welded and fixed on both clamping blocks 7.

[0029] When in use, the two clamping blocks 7 are pressed tightly against the wood, and the ends of the multiple inserts 70 are inserted into the surface of the wood, which improves the stability of the wood.

[0030] To facilitate the collection of sawdust, for example, such as Figure 1 , Figure 5 As shown, a base plate 9 is welded and fixed on the side of the slide block 15 away from the stop block 13. A collection box 10 is provided above the base plate 9. Casters are installed at the four corners of the bottom of the collection box 10. A handle is welded and fixed on one side of the collection box 10. A notch is provided on the side of the collection box 10 away from the handle. A baffle 101 is provided in the notch. A pad 8 is welded and fixed on one side of the support plate 1. The top of the pad 8 is a slope.

[0031] During use, the substrate 9 moves towards the support 2 along with the slide 15, and the collection box 10 moves accordingly. The sawdust generated during the core removal process falls into the collection box 10, which facilitates the collection of sawdust. The pad block 8, handle and casters make it easy to transfer the collection box 10 from the substrate 9 to the ground. Lifting the baffle 101 makes it easy to discharge the sawdust from the collection box 10.

[0032] To provide shielding protection for the bidirectional lead screw 30, for example, such as Figure 1 As shown, the top of the support 2 is provided with a cover plate 4.

[0033] When this utility model is in use, the output shaft of the first motor 3 drives the bidirectional lead screw 30 to rotate, the two sliders 6 move towards each other, the two clamping blocks 7 move towards each other, the two clamping blocks 7 are in close contact with the wood, and the ends of the multiple inserts 70 are inserted into the surface of the wood, which improves the stability of the wood.

[0034] The output shaft of the second motor 14 drives the card holder 16 to rotate, and the core-removing knife 17 rotates accordingly. The piston rod of the hydraulic cylinder 12 drives the slide 15 to move towards the support 2 (the hydraulic cylinder 12 is existing technology, and the specific principle will not be described in detail). It can adjust the distance between the core-removing knife 17 and the wood. The rotating core-removing knife 17 contacts the wood and moves towards the support 2 continuously, which is conducive to core removal. It not only saves manpower but also improves efficiency.

[0035] The substrate 9 moves toward the support 2 along with the slide 15, and the collection box 10 moves accordingly. The sawdust generated during the core removal process falls into the collection box 10, which facilitates the collection of sawdust. The pad block 8, handle and casters make it easy to transfer the collection box 10 from the substrate 9 to the ground. The baffle 101 is lifted to facilitate the discharge of sawdust from the collection box 10.
