Description

Technical Field

[0001] This utility model relates to the field of furniture processing technology, and in particular to a multi-blade saw for producing round logs for furniture sofa production. Background Technology

[0002] Multi-blade circular saws are one of the core pieces of equipment in furniture manufacturing, primarily used to efficiently and precisely cut whole logs into multiple planks or squares. In the furniture manufacturing industry, especially in sofa production, the quality of wood cutting directly affects subsequent processing efficiency and the aesthetics and structural strength of the finished product. Traditional log processing typically relies on single-blade saws, requiring multiple adjustments to the log's position to complete multiple cuts, which is not only time-consuming and labor-intensive but also prone to material waste due to positioning errors. As market demands for increased efficiency and precision in furniture production continue to rise, multi-blade saw technology has emerged. Through the coordinated operation of multiple sets of saw blades, it can achieve multiple cuts in a single operation, significantly improving processing efficiency.

[0003] Currently, most multi-blade circular saws for logs on the market have the following defects:

[0004] 1. Difficulty in loading: Traditional equipment often relies on manual handling or simple mechanical assistance for loading. The logs are heavy and irregular in size, making the loading process time-consuming and labor-intensive, and also posing safety hazards.

[0005] 2. Poor positioning accuracy: Logs are prone to shifting during transportation. The lack of an effective centering and positioning device leads to uneven stress on the wood during sawing, resulting in rough cuts and even waste. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a multi-blade circular saw for furniture and sofa production, which overcomes the shortcomings of the existing technology and effectively solves the problems of difficult material loading and poor positioning accuracy.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multi-blade circular saw for furniture sofa production includes a machine housing. A feeding conveyor is welded to one outer wall of the machine housing, and a discharging conveyor is welded to the other outer wall of the machine housing. Symmetrically distributed triangular blocks are arranged on the conveyor belt of the feeding conveyor.

[0009] The outer wall of one side of the feeding conveyor is provided with a log feeding mechanism, which includes a feeding frame on one side of the feeding conveyor, a winch fixed to the inner wall of the bottom of the feeding frame by screws, slide rails welded to the inner walls of both sides of the feeding frame, and a log placement plate slidably connected to the outer wall of the slide rails.

[0010] Preferably, a wire rope is wound around the outer wall of the winch, and a hook is fixedly connected to the outer wall of one end of the wire rope. A hanging ring is fixedly connected to the outer wall of the round wooden placement board, and the hook is attached to the inner wall of the hanging ring.

[0011] Preferably, the log feeding mechanism further includes a guide rod and a fixed pulley, wherein the guide rod is fixedly connected to the inner wall of the feeding frame, the fixed pulley is rotatably connected to the outer wall of the guide rod, and the wire rope on the winch is slidably connected to the outer wall of the fixed pulley.

[0012] Preferably, the lower saw blade and the upper saw blade are respectively installed inside the casing between the feeding conveyor and the discharging conveyor.

[0013] Preferably, the interior of the machine housing has adjacent positioning plates arranged on both sides of the lower and upper saw blades.

[0014] Preferably, a PLC controller is fixedly connected to one side of the outer wall of the chassis by screws.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The furniture and sofa production round log multi-blade saw designed in this paper uses a winch wire rope to pull the round log placement board up and down along the slide rail to realize the automated conveying of round logs. The cooperation between the guide rod and the fixed pulley ensures that the wire rope runs smoothly and avoids jamming. It replaces the traditional manual handling, greatly reduces labor intensity and improves material feeding efficiency.

[0017] 2. The multi-blade circular saw for furniture and sofa production designed in this paper has symmetrically distributed triangular blocks on the conveyor belt of the feeding conveyor. During the conveying process, the log is guided by the inclined surfaces of the triangular blocks on both sides and automatically adjusts to the center position of the conveyor belt, which effectively solves the problem of log offset, ensures that the wood is subjected to uniform force during sawing, the cut is flat, and the waste rate is reduced.

A feeding conveyor 2 is welded to one outer wall of the machine housing 1, and a discharging conveyor 3 is welded to the other outer wall of the machine housing 1. The conveyor belt of the feeding conveyor 2 is provided with symmetrically distributed triangular blocks 4.

[0024] The feeding conveyor 2 is responsible for transporting logs to the cutting area, while the output conveyor 3 is used to output the cut wood chips. Symmetrical triangular blocks 4 are installed on the conveyor belt of the output conveyor 3; their inclined design guides the logs to the center, preventing them from shifting.

[0025] Example 2, refer to Figure 3 A multi-blade saw for producing round logs for furniture and sofa production, wherein a round log feeding mechanism 5 is provided on one side of the outer wall of the feeding conveyor 2, and the round log feeding mechanism 5 includes a feeding frame 51 provided on one side of the feeding conveyor 2, a winch 52 fixedly connected to the bottom inner wall of the feeding frame 51 by screws, a slide rail 54 welded to the inner walls of both sides of the feeding frame 51, and a round log placement plate 53 slidably connected to the outer wall of the slide rail 54.

[0026] The winch 52 is fixed to the bottom of the loading rack 51 and pulls the log placement plate 53 up and down along the slide rail 54 via a steel wire rope. The cooperation between the guide rod 55 and the fixed pulley 56 ensures smooth operation of the steel wire rope. During operation, after the logs are loaded onto the log placement plate 53, the winch 52 starts and lifts it to the same height as the feeding conveyor 2. The logs are then pushed onto the feeding conveyor 2.

[0027] Reference Figure 3 The winch 52 has a wire rope wound around its outer wall, and a hook is fixedly connected to the outer wall of one end of the wire rope. A hanging ring is fixedly connected to the outer wall of the round wood placement plate 53, and the hook is attached to the inner wall of the hanging ring.

[0028] Reference Figure 3The log feeding mechanism 5 also includes a guide rod 55 and a fixed pulley 56. The guide rod 55 is fixedly connected to the inner wall of the feeding frame 51, and the fixed pulley 56 is rotatably connected to the outer wall of the guide rod 55. The wire rope on the winch 52 is slidably connected to the outer wall of the fixed pulley 56.

[0029] Reference Figure 1 Inside the housing 1, between the feeding conveyor 2 and the discharging conveyor 3, a lower saw blade 6 and an upper saw blade 7 are respectively installed.

[0030] Reference Figure 1 The machine housing 1 has adjacent positioning discs 8 arranged on both sides of the lower saw blade 6 and the upper saw blade 7 inside the housing 1.

[0031] The lower saw blade 6 and the upper saw blade 7 are installed inside the casing 1 for cutting logs. Positioning discs 8 are provided on both sides of the saw blades to mechanically limit the movement path of the logs and ensure the stability of the wood during the cutting process.

[0032] Reference Figure 1 A PLC controller 9 is fixedly connected to one side of the outer wall of the chassis 1 by screws.

[0033] Working principle:

[0034] 1. Loading Stage: The operator places the logs on the log placement plate 53, starts the winch 52, and the wire rope pulls the placement plate along the slide rail 54 to the height of the feeding conveyor 2 via the fixed pulley 56. The logs are pushed to the feeding conveyor 2, and the triangular blocks 4 on the conveyor belt guide the logs to automatically center themselves through the inclined plane. The conveyor belt then feeds them into the cutting area at a uniform speed.

[0035] 2. Cutting Stage: After the log enters the machine housing 1, the positioning plate 8 restricts its lateral displacement, ensuring that the center of the log is aligned with the saw blade. The lower saw blade 6 and the upper saw blade 7 rotate synchronously at high speed, cutting the log into multiple pieces in one pass.

[0036] 3. Discharge stage: The cut wood chips are output via discharge conveyor 3.

[0037] 4. Intelligent control: The PLC controller 9 monitors the operating status of each link in real time and automatically adjusts the conveying speed and saw blade parameters to ensure cutting accuracy and efficiency.
