Description

Technical Field

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

[0002] In the wood processing industry, there is a wide variety of cutting devices, with different tools corresponding to specific usage scenarios. For example, hand saws, circular saws, and band saws each play a unique role. Among them, the band saw, as a sawing tool, uses a continuous metal band with serrated edges for cutting operations. Band saws are particularly favored in the processing of large logs, as they can efficiently complete the trimming and cutting of logs.

[0003] Patent CN218699677U discloses a band saw machine, including a frame, a worktable, and a band saw blade. The worktable is mounted on the frame and has a saw groove. The band saw blade is positioned within the saw groove. A lead screw rotates the worktable, and a baffle is provided on the worktable to restrict one side of the wooden board. The lead screw drives the baffle to slide on the worktable surface. A stabilizing device is fixedly mounted on the frame above the band saw blade. The stabilizing device includes a connecting plate and three limiting wheels. The connecting plate is fixedly connected to the frame, and the three limiting wheels are rotatably connected to the connecting plate. The edges of the three limiting wheels respectively engage with both sides of the band saw blade and the opposite side of the saw teeth. The baffle can be adjusted to adapt to various cutting requirements, ensuring stable operation of the band saw blade and improving equipment operating efficiency.

[0004] However, the wood processing device described above still has the following problems: During the cutting of long timber using a band saw, as the cutting process continues, the originally whole piece of timber is gradually split into two pieces. During this period, because the timber near the inside of the band saw lacks an effective support structure, it will experience significant downward displacement under the influence of gravity. When the cutting operation is completely completed, the piece of timber, having lost the restraint during cutting, will instantly separate from the parent material and fall off. Due to the lack of cushioning and protection measures, the timber will violently collide with the ground during free fall, easily causing quality problems such as surface damage and structural damage. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a cutting device for wood processing, which improves the safety of wood cutting and processing operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for wood processing, including a band saw and a band saw table, with an outer clamping component and an inner clamping component respectively provided on both sides of the band saw table, the outer clamping component and the inner clamping component being arranged opposite to each other, both the outer clamping component and the inner clamping component being located at the rear end of the band saw cutting, an adjusting component being connected to the side of the inner clamping component away from the outer clamping component, and a driven component being connected between the outer clamping component and the adjusting component.

[0007] Furthermore, the driven component includes a connecting plate and several trapezoidal slide rods. Several trapezoidal slide grooves are provided at the bottom of the rear end of the band saw table. The trapezoidal slide rods are slidably connected to the trapezoidal slide grooves respectively. The connecting plate is fixedly connected to the bottom of the trapezoidal slide rods. The adjusting component and the external clamping component are respectively connected to both ends of the connecting plate.

[0008] Furthermore, the outer clamping assembly includes an L-shaped support frame, a U-shaped outer roller frame, and several outer clamping rollers. The L-shaped support frame is fixedly connected to the end of the connecting plate away from the band saw, and the other end of the L-shaped support frame is fixedly connected to the U-shaped outer roller frame. The U-shaped outer roller frame is located above the band saw table. The two ends of several outer clamping rollers are rotatably connected to the two ends of the U-shaped outer roller frame through rotating shafts, and the several outer clamping rollers are all set perpendicular to the surface of the band saw table.

[0009] Furthermore, the adjustment assembly includes a support plate and a telescopic component. The support plate is fixedly connected to the end of the connecting plate away from the outer clamping assembly, and the telescopic component is fixedly connected to the side of the support plate away from the outer clamping assembly. The telescopic end of the telescopic component passes through the support plate and is connected to the inner clamping assembly.

[0010] Furthermore, the inner clamping assembly includes a U-shaped inner roller frame and several inner clamping rollers. The two ends of the several inner clamping rollers are rotatably connected to the two ends of the U-shaped inner roller frame through rotating shafts, and the several inner clamping rollers are all set perpendicular to the surface of the band saw table. The telescopic end of the telescopic component passes through the support plate and is fixedly connected to the side of the U-shaped inner roller frame away from the inner clamping rollers.

[0011] Furthermore, both ends of the U-shaped inner roller frame near the telescopic component are fixedly connected with reinforcing rods, and the other ends of the two reinforcing rods pass through the support plate and are slidably connected to the support plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This wood processing cutting device, by setting external clamping components and internal clamping components on both sides of the band saw table, can clamp the two pieces of wood after cutting, thereby preventing the two pieces of wood from bending and deforming. At the same time, after the two pieces of wood are completely cut, it can prevent the two pieces of wood from falling under the band saw table and being damaged, thus improving the stability of the wood cutting operation and the safety of the wood after cutting.

[0020] 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 the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 5 A cutting device for wood processing includes a band saw 1 and a band saw table 2. An outer clamping component 3 and an inner clamping component 4 are respectively provided on both sides of the band saw table 2. The outer clamping component 3 and the inner clamping component 4 are arranged opposite to each other. Both the outer clamping component 3 and the inner clamping component 4 are located at the rear end of the band saw 1 for cutting. An adjustment component 6 is connected to the side of the inner clamping component 4 away from the outer clamping component 3. A driven component 5 is connected between the outer clamping component 3 and the adjustment component 6.

[0022] like Figures 1 to 5 As shown, the wood cutting device of this utility model is structurally similar to existing wood cutting devices, such as the band saw disclosed in patent publication number CN218699677U. The main improvement of this utility model lies in improving the stability and safety of the cutting process and the two pieces of wood after cutting. Figures 1 to 5As shown, in the wood processing cutting device of this utility model, when the wood is placed on the band saw table 2 and cut by the band saw machine 1, the wood with the cut moves between the outer clamping component 3 and the inner clamping component 4. At this time, the adjusting component 6 drives the inner clamping component 4 to move towards the side of the wood facing the band saw machine 1. When the inner clamping component 4 contacts the wood, the squeezing force generated by the continued movement drives the outer clamping component 3 to move towards the inner clamping component 4 through the driven component 5, so that the outer clamping component 3 squeezes to the other side of the wood. At this time, the inner clamping component 4 and the outer clamping component 3 can cooperate with each other to squeeze and clamp the two pieces of wood after cutting towards the middle, thereby preventing the two pieces of wood from moving away from each other and tilting, which would cause the wood to deform or bend, and improving the stability of the wood cutting process. As the wood continues to be cut, when the wood is completely cut, the inner clamping component 4 and the outer clamping component 3 clamp and fix the two pieces of wood that have been completely cut and separated together, thereby preventing the two pieces of wood from falling off the band saw table 2, avoiding the problem of wood falling and injuring the operator, and improving the safety of wood cutting and processing.

[0023] like Figures 1 to 2 As shown, the driven component 5 includes a connecting plate 51 and several trapezoidal slide rods 52. Several trapezoidal slide grooves 201 are provided at the bottom of the rear end of the band saw table 2. Several trapezoidal slide rods 52 are slidably connected to several trapezoidal slide grooves 201 respectively. The connecting plate 51 is fixedly connected to the bottom of several trapezoidal slide rods 52. The adjusting component 6 and the outer clamping component 3 are respectively connected to the two ends of the connecting plate 51. When the adjusting component 6 causes the inner clamping component 4 to press against one side of the wood, the reaction force causes the connecting plate 51 to move towards the inner clamping component 4, thereby completing the mutual pressing and fixing of the two pieces of wood by the inner clamping component 4 and the outer clamping component 3. It should be noted that the wood is stable on the band saw table 2 by gravity and slides longitudinally on the band saw table 2. When the adjusting component 6 causes the inner clamping component 4 to press against one side of the wood, the wood will not be misaligned on the band saw table 2, thereby ensuring that the connecting plate 51 slides in the trapezoidal slide groove 201 at the bottom of the band saw table 2 through the trapezoidal slide rod 52, thereby causing the outer clamping component 3 to press against the other side of the wood, completing the pressing and fixing of the two pieces of wood.

[0024] like Figures 1 to 5As shown, the outer clamping assembly 3 includes an L-shaped support frame 31, a U-shaped outer roller frame 32, and several outer clamping rollers 33. The L-shaped support frame 31 is fixedly connected to the end of the connecting plate 51 away from the band saw 1, and the other end of the L-shaped support frame 31 is fixedly connected to the U-shaped outer roller frame 32. The U-shaped outer roller frame 32 is located above the band saw table 2. The two ends of several outer clamping rollers 33 are rotatably connected to the two ends of the U-shaped outer roller frame 32 through rotating shafts, and the several outer clamping rollers 33 are all arranged perpendicularly to the surface of the band saw table 2. The L-shaped support frame 31 and the U-shaped outer roller frame 32 are supported and fixed above the band saw table 2. When the U-shaped outer roller frame 32 moves inward toward the clamping assembly 4 to clamp the wood, it can ensure that the outer clamping roller 33 can squeeze to the outside of the wood, while the other end of the L-shaped support frame 31 will not contact or obstruct the band saw table 2. When the wood is moving and cutting, the outer clamping roller 33, which rotates inside the U-shaped outer roller frame 32 via the pivot, can ensure that the wood can continue to move forward and cut while clamping the wood, thus ensuring that the wood cutting operation and clamping and fixing are carried out synchronously. It should be noted that the roller body of the outer clamping roller 33 needs to protrude from the U-shaped outer roller frame 32 so that when the outer clamping roller 33 contacts the wood surface, the U-shaped outer roller frame 32 does not contact or obstruct the wood.

[0025] like Figures 1 to 5 As shown, the adjusting component 6 includes a support plate 61 and a telescopic component 62. The support plate 61 is fixedly connected to the end of the connecting plate 51 away from the outer clamping component 3. The telescopic component 62 is fixedly connected to the side of the support plate 61 away from the outer clamping component 3. The telescopic end of the telescopic component 62 passes through the support plate 61 and connects to the inner clamping component 4. The support plate 61 is used to support the telescopic component 62. When the telescopic component 62 extends or retracts, it drives the inner clamping component 4 to gradually move closer to the outer clamping component 3, thereby clamping the wood between the inner clamping component 4 and the outer clamping component 3. The telescopic component 62 can be an electric actuator, a cylinder, or a hydraulic rod. When the telescopic component 62 drives the inner clamping component 4 and the outer clamping component 3 to clamp and fix the cutting wood on both sides, the clamping force needs to be adjusted according to the pressure resistance of the wood to avoid over-clamping the wood and causing it to break.

[0026] like Figures 1 to 4 As shown, the inner clamping assembly 4 includes a U-shaped inner roller frame 41 and several inner clamping rollers 42. The two ends of the inner clamping rollers 42 are rotatably connected to the two ends of the U-shaped inner roller frame 41 via rotating shafts. All the inner clamping rollers 42 are perpendicular to the surface of the band saw table 2. The telescopic end of the telescopic member 62 passes through the support plate 61 and is fixedly connected to the side of the U-shaped inner roller frame 41 away from the inner clamping rollers 42. The inner clamping rollers 42 are supported by the U-shaped inner roller frame 41. After clamping the wood, the inner clamping rollers 42 and the outer clamping rollers 33 can rotate as the wood moves forward, achieving the clamping purpose without obstructing the cutting operation. The telescopic member 62 pushes the U-shaped inner roller frame 41, causing the inner clamping rollers 42 to gradually approach and press against one side of the wood.

[0027] like Figures 1 to 5 As shown, both ends of the U-shaped inner roller frame 41 near the telescopic member 62 are fixedly connected to reinforcing rods 63. The other ends of the two reinforcing rods 63 pass through the support plate 61 and are slidably connected to the support plate 61. When the telescopic member 62 drives the U-shaped inner roller frame 41 to extend and retract, the two reinforcing rods 63 can provide additional reinforcement support for the U-shaped inner roller frame 41, preventing the telescopic end of the telescopic member 62 from bending and improving the stability of the telescopic member 62.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
