Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a wood cutting device. Background Technology

[0002] Wood is a collective term for plant tissues that develop inward from the vascular cambium, including the xylem and parenchyma rays. Wood plays a significant supporting role in human life and is widely used in production and daily life. Depending on the application, wood is usually processed into various shapes. Specifically, before use, raw wood is processed into general-sized planks, square columns, trapezoids, round columns, elliptical columns, prisms, and other shapes. When producing specific wood products, the general-sized wood is further processed, such as cutting the wood into small planks or strips. In traditional operations, wood is typically cut using a woodworking table saw. The operator installs a stop block on the table, adjusts the stop block to the appropriate position according to the size of the piece to be cut, then places the wood against the stop block and pushes the wood toward the saw blade. Once the wood has completely passed the saw blade, it is cut to the set size. When the wood can be cut into multiple planks or strips of the set size, the remaining wood needs to be moved back to the initial position and the cutting action is repeated. This method can cut wood into predetermined sizes according to usage requirements, but it is highly dependent on manual operation, requiring manual back-and-forth movement of the wood, resulting in low efficiency and high labor intensity. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a wood cutting device.

[0004] This utility model is achieved using the following solution:

[0006] Furthermore, both the active component and the driven component include a connecting frame connected to the machine base, a rotating shaft connected to the connecting frame, and a first transmission wheel connected to the rotating shaft. The transmission belt is connected to the first transmission wheel of the active component and the first transmission wheel of the driven component. The rotating shaft of the active component is also connected to a second transmission wheel, and the second transmission wheel is connected to the conveying drive component.

[0007] Furthermore, the machine base is provided with an elongated hole extending along the conveying direction of the conveying mechanism at the position corresponding to the position of the pusher, and the pusher extends through the elongated hole to the top of the machine base.

[0008] Furthermore, the cutting mechanism also includes a cutting frame mounted on the machine base, a cutting shaft connected to the cutting frame, and a cutting drive component for driving the cutting shaft to rotate. A plurality of the circular saw blades are coaxially arranged side by side on the cutting shaft, and the cutting shaft is provided with an adjustment and locking component that matches the circular saw blades.

[0009] Furthermore, the number of the adjusting locking components corresponds to the number of the circular saw blades, and each locking component includes two locking rings connected to the cutting shaft, with the circular saw blades located between the two locking rings.

[0010] Furthermore, a cutting plate is detachably connected to the machine base at the position corresponding to the cutting mechanism, and the cutting plate is provided with cutting holes corresponding to the circular saw blade.

[0011] Furthermore, the wood cutting device also includes a positioning and guiding mechanism, which includes a first guiding component and a second guiding component disposed on the machine base, with a gap between the first guiding component and the second guiding component.

Detailed Implementation

[0023] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0024] Reference Figures 1 to 4 This utility model provides a wood cutting device, including a machine base 1, a cutting mechanism 2 disposed on the machine base 1, and a conveying mechanism 3 connected to the machine base 1. The cutting mechanism 2 is located in the conveying direction of the conveying mechanism 3. The wood to be cut is placed on the top surface of the machine base 1 and moves towards the cutting mechanism 2 under the conveying of the conveying mechanism 3 to perform the cutting operation.

[0025] The conveying mechanism 3 includes an active component 31 connected to the machine base 1, a driven component 32 connected to the machine base 1, and a conveying drive component 33 for driving the active component 31. The active component 31 and the driven component 32 are connected by a transmission belt 34, on which a pusher 35 is provided, extending above the top surface of the machine base 1. In this embodiment, the machine base 1 specifically includes a frame and a platform disposed on top of the frame. The conveying mechanism 3 is disposed below the platform, and the pusher 35 extends above the platform. The active component 31 is located near one end of the machine base 1, and the driven component 32 is located near the other end of the machine base 1.

[0026] like Figure 2 As shown, both the active component 31 and the driven component 32 include a connecting frame 311 connected to the machine base 1, a rotating shaft 312 connected to the connecting frame 311, and a first transmission wheel 313 connected to the rotating shaft 312. A transmission belt 34 is connected to the first transmission wheel 313. Specifically, the transmission belt 34 connects both the first transmission wheel of the active component 31 and the first transmission wheel of the driven component 32. The rotating shaft 312 of the active component 31 is also connected to a second transmission wheel 314, which is connected to the conveying drive component 33. A third transmission wheel is provided at the output end of the conveying drive component 33. The second transmission wheel 314 and the third transmission wheel can also be driven by the transmission belt 34 (not shown in the figure) or by a chain.

[0027] The machine base 1 has an elongated hole 11 corresponding to the position of the pusher 35, and the pusher 35 extends through the elongated hole 11 to the top of the machine base 1. Specifically, the elongated hole 11 is a slender hole set along the length direction of the table surface (the conveying direction of the conveying mechanism). The pusher 35 moves along the elongated hole 11, pushing the wood towards the cutting assembly. In addition, a push plate can also be set at the upper end of the pusher 35 to improve the stability of the pushing process.

[0028] The cutting mechanism 2 includes a cutting frame 22 mounted on the machine base 1, a cutting shaft 23 connected to the cutting frame 22, a plurality of circular saw blades 21 mounted on the cutting shaft 23, and a cutting drive component 24 for driving the cutting shaft 23 to rotate. An adjustment and locking assembly 25 matching the circular saw blades 21 is mounted on the cutting shaft 23. The cutting drive component 24 is connected to the cutting shaft 23 via a synchronous pulley (not shown in the figure).

[0029] The adjusting locking component 25 can precisely adjust the position of the circular saw blades 21 on the cutting axis 23, thereby enabling flexible adjustment of the spacing between adjacent circular saw blades 21. This allows for the fulfillment of cutting requirements for different sizes, greatly improving the versatility and applicability of the equipment. For example, when cutting wider materials, the spacing between adjacent circular saw blades 21 can be appropriately increased by adjusting the locking component 25 to ensure the integrity and accuracy of the cut. Conversely, when cutting narrower materials, the spacing between adjacent circular saw blades 21 can be decreased to improve cutting efficiency and reduce material waste.

[0030] like Figure 3 As shown, the number of adjusting locking components 25 corresponds to the number of circular saw blades 21. Each locking component includes two set rings 251 connected to the cutting shaft 23. The set rings 251 are locked and fixed to the cutting shaft 23 by set screws. The circular saw blade 21 is located between the two set rings 251, forming a clamping structure that securely holds the circular saw blade 21 in the middle. The adjusting locking components 25 effectively prevent the circular saw blade 21 from shifting or loosening during high-speed rotation, ensuring the stability and safety of the cutting process. Furthermore, by adjusting the distance between the two set rings 251, the specific position of the circular saw blade 21 on the cutting shaft 23 can be flexibly changed. Tightening and loosening the set rings 251 only requires turning the set screws, making the operation convenient and quick.

[0031] A cutting plate 12 is detachably connected to the machine base 1 at the position corresponding to the cutting mechanism 2. The cutting plate 12 has cutting holes 13 corresponding to the circular saw blade 21. The cutting holes 13 are elongated holes, allowing the circular saw blade 21 to enter and ensure that it can pass over the bottom surface of the wood for a complete cut. The cutting plate 12 and the table surface of the machine base 1 are detachably connected. Cutting plates 12 of different sizes can be pre-set, and the corresponding cutting plate 12 can be replaced according to the size specifications to be cut during the cutting operation.

[0032] like Figure 4As shown, the wood cutting device includes a positioning and guiding mechanism 4. The positioning and guiding mechanism 4 includes a first guiding component 41 and a second guiding component 42 mounted on the machine base 1. There is a gap between the first guiding component 41 and the second guiding component 42, and the wood is placed at this gap. The first guiding component 41 includes a guiding drive member 411 mounted on the machine base 1, a guide bracket 412 connected to the output end of the guiding drive member 411, and a plurality of first guide wheels 413 mounted on the guide bracket 412. The guiding drive member 411 is a cylinder, which drives the guide bracket 412 to move towards the second guiding component 42, thereby cooperating with the second guiding component 42 to press the wood from both sides, preventing the wood from shifting during movement. Furthermore, in a specific implementation, the table surface of the machine base 1 can be provided with guide grooves or guide rails to improve the stability of the guide bracket 412's movement.

[0033] The second guide assembly 42 includes a guide seat 421 disposed on the machine base 1 and a plurality of second guide wheels 422 disposed on the guide seat 421. The machine base 1 is provided with a connecting groove 14 that matches the guide seat 421. Specifically, the connecting groove 14 is disposed on the table surface of the machine base 1. The guide seat 421 can move along the connecting groove 14 to adjust its position. After adjusting to a suitable position, the guide seat 421 is locked in place by fasteners. Thus, the second guide assembly 42 can be pre-adjusted according to the size of the wood to be cut to ensure that the wood is centered.

[0034] The connecting groove 14 is a T-shaped groove, and the guide seat 421 is locked to the connecting groove 14 by fasteners. Specifically, a nut can be pre-embedded in the T-shaped groove, and a screw passes through the guide seat 421 and connects with the nut to lock the guide seat 421 onto the table surface of the machine base 1.

[0035] In actual operation, firstly, adjust the number and spacing of the circular saw blades 21 according to the size to be cut, and install the corresponding cutting plate 12, while adjusting the position of the second guide component 42. During cutting, place the wood on the table of the machine platform 1, ensuring the end face of the wood contacts the push plate at the pusher 35. The first guide component 41 presses down on the wood, and then the conveying mechanism 3 transports the wood towards the cutting mechanism 2. The cutting mechanism 2 then starts cutting the wood. In specific implementation, a traction mechanism (such as two sets of corresponding traction rollers) can be installed at the end of the machine platform 1 to pull the wood. After passing through the cutting mechanism 2, the wood is divided into small strips or boards. The traction mechanism cooperates with the conveying mechanism 3 to pull the strips or boards further, and then sends the strips or boards out of the machine platform 1.
