Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically a single-blade longitudinal saw. Background Technology

[0002] A single-blade rip saw is a type of machinery used for wood processing, primarily for cutting logs or boards longitudinally (along the grain) to the desired width or thickness. It is typically equipped with a high-speed rotating circular saw blade, suitable for precise straight-line cutting, and is widely used in industries such as furniture manufacturing, construction woodworking, and flooring production.

[0003] In existing single-blade rip saws, the high-speed rotating saw blade generates a large amount of sawdust during wood cutting operations. Due to the lack of effective collection devices, the sawdust scatters everywhere, polluting the working environment. Furthermore, single-blade rip saws usually rely solely on manual pressing or simple clamps to hold the wood in place. During high-speed cutting, the wood is prone to shifting or vibrating, resulting in tilted cut surfaces or dimensional errors, which affects the cutting efficiency of the single-blade rip saw. Utility Model Content

[0004] The purpose of this utility model is to provide a single-blade rip saw to solve the problems mentioned in the background art. In the cutting of wood, the high-speed rotating saw blade of the existing single-blade rip saw produces a large amount of sawdust. Due to the lack of an effective collection device, the sawdust will fly around and pollute the working environment. In addition, the single-blade rip saw usually relies on manual pressing or simple clamps to fix the wood. During high-speed cutting, the wood is prone to displacement or vibration, resulting in tilting of the cut surface or dimensional errors, which affects the cutting efficiency of the single-blade rip saw.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-blade longitudinal saw, comprising a base, a clamping part, and a cleaning part:

[0006] The base has a workbench on top, a saw blade on the top surface of the workbench, a clamping part on top of the base, a connecting frame on the side of the workbench, a clamping frame for holding wood that slides laterally on the top surface of the connecting frame, a cleaning part on top of the base, a support frame on the top surface of the workbench, a lifting frame that slides vertically inside the support frame, a lifting cover for covering the cutting part that slides vertically at the bottom of the lifting frame, a vacuum cleaner on the side of the support frame, a connecting pipe on the side of the vacuum cleaner that communicates with the lifting cover.

[0007] By adopting the above technical solution, the clamping position can be adjusted by sliding the clamping frame laterally to accommodate wood of different sizes. At the same time, the lifting cover, together with the vacuum cleaner, collects the wood chips generated during cutting in real time, keeping the workbench clean and improving safety and work efficiency.

[0008] Preferably, the clamping part also has side pulleys neatly arranged on the side of the clamping frame, which abut against the side of the wood. There are two clamping frames, which are arranged in a mirror symmetrical manner along the saw blade.

[0009] By adopting the above technical solution, the frictional resistance between the wood and the clamping frame can be reduced by the side pulley, ensuring that the wood moves smoothly during the cutting process. The symmetrical design of the double clamping frame can apply force evenly and avoid wood deviation that could lead to cutting errors.

[0010] Preferably, the clamping part also has a drive shaft that is laterally rotatably disposed inside the connecting frame. There are two drive shafts. The bottom of the clamping frame is provided with a threaded groove. The drive shaft passes through the threaded groove and is nested and threadedly connected to the clamping frame.

[0011] By adopting the above technical solution, the clamping frame can be moved laterally along the threaded groove by rotating the drive shaft, so as to achieve precise adjustment of the clamping distance and adapt to the processing needs of wood of different widths.

[0012] Preferably, the clamping part also has a drive shaft that is longitudinally rotatably disposed inside the connecting frame. Both ends of the drive shaft are provided with bevel teeth b, and one end of the drive shaft is provided with bevel teeth a. The bevel teeth a and bevel teeth b are connected in a transmission manner. A motor is provided on the side of the connecting frame, and the output end of the motor is connected to one of the drive shafts.

[0013] By adopting the above technical solution, the bevel gear a and bevel gear b can be meshed and transmitted by the motor, and the rotation of the two drive shafts can be controlled synchronously to ensure that the clamping frames on both sides move synchronously and avoid the wood being clamped off-center.

[0014] Preferably, the cleaning unit also has a cylinder disposed on the top of the support frame, the output end of which is connected to the top of the lifting frame.

[0015] By adopting the above technical solution, the lifting frame can be moved up and down by a cylinder, which can cause the lifting cover to adapt to wood of different thicknesses, ensuring that the cutting part is always effectively covered and improving the dust collection effect.

[0016] Preferably, the cleaning unit also has a limiting rod disposed on the top of the lifting hood, the limiting rod being embedded in the lifting frame and vertically slidably connected to the lifting frame.

[0017] By adopting the above technical solution, the movement trajectory of the lifting cover can be constrained by the limit rod, preventing it from swaying horizontally and ensuring that the lifting cover maintains stable contact with the top surface of the wood.

[0018] Preferably, the cleaning unit also has a spring disposed at the bottom of the lifting frame, the spring being nested outside the limiting rod, and the spring being located between the lifting frame and the lifting cover.

[0019] By adopting the above technical solution, the pressure between the lifting cover and the wood can be buffered by the elastic deformation of the spring, thus avoiding damage to the wood surface.

[0020] Preferably, the cleaning section also has pressure rollers disposed at the bottom of both sides of the lifting cover, which abut against the top surface of the wood.

[0021] By adopting the above technical solution, the pressure roller can roll into contact with the top surface of the wood, reducing the frictional resistance when the lifting cover moves and ensuring smooth feeding of the wood.

[0022] Compared with the prior art, the beneficial effects of this utility model are: by providing a clamping part and a cleaning part, the clamping position can be adjusted by the horizontal sliding of the clamping frame to adapt to wood of different sizes. At the same time, the lifting cover, together with the vacuum cleaner, collects the wood chips generated by cutting in real time, keeps the workbench clean, and improves safety and work efficiency.

The connecting pipe 307 is connected to the lifting cover 304. The clamping position can be adjusted by sliding the clamping frame 202 laterally to adapt to different sizes of wood. At the same time, the lifting cover 304 works with the vacuum cleaner 308 to collect the wood chips generated during cutting in real time, keeping the workbench 101 clean and improving safety and work efficiency.

[0033] Example 2

[0034] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: a single-blade longitudinal saw, including a clamping part 2, a clamping frame 202, and a drive shaft 204.

[0035] Side pulleys 203 are fixedly installed on the side of the clamping frame 202. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. The side pulleys 203 abut against the side of the wood. There are two clamping frames 202. The two clamping frames 202 are arranged in a mirror symmetrical manner along the saw blade 102. The side pulleys 203 can reduce the frictional resistance between the wood and the clamping frame 202, ensuring that the wood moves smoothly during the cutting process. The symmetrical design of the double clamping frames 202 can apply force evenly and avoid wood deviation that causes cutting errors.

[0036] Inside the connecting frame 201, there is a drive shaft 204 that rotates laterally. There are two drive shafts 204. The drive shaft 204 is a bidirectional lead screw. The bidirectional lead screw is a special lead screw structure. Its core feature is that it can achieve two opposite movements on the same lead screw. The above is the prior art and will not be described in detail below. The bottom of the clamping frame 202 has a threaded groove 208. The drive shaft 204 passes through the threaded groove 208 and is nested and threadedly connected to the clamping frame 202. The rotation of the drive shaft 204 can drive the clamping frame 202 to move laterally along the threaded groove 208, so as to achieve precise adjustment of the clamping distance and adapt to the processing needs of wood of different widths.

[0037] A drive shaft 206 is longitudinally rotatably arranged inside the connecting frame 201. Both ends of the drive shaft 206 are provided with bevel teeth b207. One end of the drive shaft 204 is provided with bevel teeth a205. Bevel teeth a205 and bevel teeth b207 are connected in a transmission manner. A motor 209 is provided on the side of the connecting frame 201. The output end of the motor 209 is connected to one of the drive shafts 204. The motor 209 can drive bevel teeth a205 and bevel teeth b207 to mesh and transmit power, and synchronously control the rotation of the two drive shafts 204 to ensure that the clamping frames 202 on both sides move synchronously and avoid the wood clamping deviation.

[0038] Example 3

[0039] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: a single-blade longitudinal saw, including a cleaning unit 3, a lifting cover 304, and a pressure roller 306.

[0040] A cylinder 302 is fixedly installed on the top of the support frame 301. The fixing method is an existing detachable fixing, such as bolt connection, buckle connection, etc. The output end of the cylinder 302 is connected to the top of the lifting frame 303. The lifting frame 303 can be moved up and down by the cylinder 302, which drives the lifting cover 304 to adapt to wood of different thicknesses, ensuring that the cutting part is always effectively covered and improving the dust collection effect.

[0041] A limit rod 305 is integrally installed on the top of the lifting cover 304. The limit rod 305 is embedded in the lifting frame 303 and is vertically slidably connected to the lifting frame 303. The limit rod 305 can constrain the movement trajectory of the lifting cover 304, prevent it from swaying horizontally, and ensure that the lifting cover 304 maintains stable contact with the top surface of the wood.

[0042] A spring 309 is provided at the bottom of the lifting frame 303. The spring 309 is nested outside the limiting rod 305. The spring 309 is located between the lifting frame 303 and the lifting cover 304. The elastic deformation of the spring 309 can buffer the pressure between the lifting cover 304 and the wood, and prevent damage to the surface of the wood.

[0043] Pressure rollers 306 are fixedly installed on the bottom of both sides of the lifting cover 304. The fixing method is the existing detachable fixing, such as bolt connection, snap connection, etc. The pressure rollers 306 abut against the top surface of the wood. The pressure rollers 306 can roll to contact the top surface of the wood, reducing the frictional resistance when the lifting cover 304 moves and ensuring smooth feeding of the wood.

[0044] Working principle: First, the device is powered on. Then, the operator places the wood to be cut on the workbench 101 and starts the motor 209. The motor 209 drives one of the drive shafts 204 to rotate. Through the meshing of bevel gear a205 and bevel gear b207, the drive shaft 206 is driven to rotate, thereby making the two drive shafts 204 rotate synchronously. The drive shaft 204 is a two-way lead screw structure. When rotating, it drives the two clamping frames 202 to move in opposite directions along the threaded groove 208, adjusting the clamping distance to adapt to the width of the wood. The side pulley 203 rolls in contact with the side of the wood, reducing frictional resistance and ensuring that the wood is fed smoothly to the cutting position of the saw blade 102. When the wood is fed, the saw blade 102 is driven to rotate at high speed by the power source in the base 1 to complete the longitudinal cutting. The cylinder 302 pushes the lifting frame 303 down, causing the lifting cover 304 to fit against the top surface of the wood. The pressure roller 306 rolls in contact with the wood to reduce friction. The spring 309 buffers the pressure of the lifting cover 304 to avoid damaging the surface of the wood. The vacuum cleaner 308 is connected to the lifting cover 304 through the connecting pipe 307 to suck up the wood chips generated by cutting in real time, keeping the workbench 101 clean and preventing wood chips from splashing and affecting operational safety.
