Description

Technical Field

[0001] The utility model relates to a safe and reliable intelligent square timber multi-blade sawing machine, belonging to the technical field of wood processing equipment. Background Art

[0002] Wood is a commonly used material in our daily lives. Currently, when using wood, it usually needs to be sawed to cut it into boards of the required size. Traditional sawing equipment cannot effectively fix the wood in position during cutting, causing the wood to easily shift in position when being cut by the saw wheel, resulting in reduced sawing quality of the board.

[0003] To this end, in the prior art, a utility model patent with Chinese patent authorization publication number CN214819218U discloses a novel wood cutting device. During the wood processing process, the device uses a lower supporting active wheel mechanism to transport the wood, and an upper pressure wheel mechanism to pressurize the top of the wood to maintain the position of the wood stable. The upper and lower bulletproof devices can prevent the wood board from vibrating during the cutting process, which may cause the position of the wood board to shift, thereby ensuring the quality of the board after sawing. However, in actual use, the device still has the following problems:

[0004] 1. It only installs a bulletproof device at the feeding position of the wood to compress and bulletproof the wood, but does not install a corresponding bulletproof device at the discharging position. This will result in that if the wood at the discharging position rebounds, it will easily affect the life and health of the people receiving the wood.

[0005] 2. During the material feeding process, the material can only be cut manually. However, due to manual operation, workers are inevitably careless or lack experience during the operation, which will lead to operational errors when feeding, resulting in a large amount of wood waste and increased costs for the company.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example: Please refer to Figures 1 to 6 This embodiment provides a safe and reliable intelligent multi-blade saw for square timber, comprising a frame 1, on which are disposed a feeding mechanism 2, a sawing mechanism 3, and a discharge port 4. The feeding mechanism 2 is used to transport wooden boards and can be a common conveyor belt, conveyor roller, or other structure in the prior art. The sawing mechanism 3 is used to process the wooden boards into the desired board material. The sawing mechanism 3 can be a common sawing wheel, sawing roller, or other structure in the prior art. To improve the applicability of the sawing mechanism 3, the sawing mechanism 3 can also be a common sawing roller assembly with adjustable height, such as in the prior art, to accommodate processing wood boards of varying thicknesses. The discharge port 4 is used for discharging the wood.

[0031] To ensure the safety of the material receiving personnel, in this embodiment, a bulletproof assembly 5 is provided on the material outlet 4. The bulletproof assembly 5 includes a mounting plate 51, which is fixedly mounted above the material outlet 4 and arranged horizontally above the material outlet 4. The bottom wall of the mounting plate 51 is provided with fixed blocks 52 arranged symmetrically on both sides. A rotating shaft 53 is rotatably connected between the fixed blocks 52 on both sides. The right end of the rotating shaft 53 is movably inserted into the fixed block 52 on the right side. A torsion spring 56 is sleeved on the right end of the rotating shaft 53. The left end of the torsion spring 56 is connected to the right end of the rotating shaft 53, and the right end of the torsion spring 56 is connected to the fixed block 52 on the right side. The provision of the torsion spring 56 allows the rotating shaft 53 to have elastic energy storage, thereby providing support for subsequent work. The shaft wall of the rotating shaft 53 is provided with a first mounting block 54, and the bottom wall of the first mounting block 54 is connected to a bulletproof baffle 55, which is arranged to cover the material outlet 4. To ensure the connection effect, multiple first mounting blocks 54 can be set on the shaft wall of the rotating shaft 53. In this embodiment, the number of first mounting blocks 54 is 3, and the first mounting blocks 54 are evenly distributed on the shaft wall of the rotating shaft 53. The top of the bulletproof baffle 55 is connected to the bottom walls of the three first mounting blocks 54 to ensure the connection stability between the bulletproof baffle 55 and the rotating shaft 53.

[0032] When the plate is ejected from the discharge port 4, the bulletproof baffle 55 is pushed outward by the sawing mechanism 3, so that the bulletproof baffle 55 rotates accordingly under the action of the rotating shaft 53, so that a gap that can pass through the plate appears between the bottom of the bulletproof baffle 55 and the discharge port 4, and the plate can be output outward with the help of this gap. When the plate rebounds, the blocking effect of the bulletproof baffle 55 can prevent the rebounded plate from hitting the material receiving personnel. Compared with the existing technology, it has the advantage of ensuring the life and health of the material receiving personnel. At the same time, when the rotating shaft 53 rotates, it will drive the torsion spring 56 to rotate, causing the torsion spring 56 to deform, so that the rotating shaft 53 has elastic energy storage, so that the rotating shaft 53 has a tendency to drive the bulletproof baffle 55 to perform a reset movement, so that the bulletproof baffle 55 can press the plate output outward from the gap between its bottom and the discharge port 4, thereby maintaining the position of the plate and avoiding the plate from being offset due to the vibration generated by the machine tool during the discharge process.

[0033] In order to further strengthen the connection between the rotating shaft 53 and the bulletproof baffle 55, a second mounting block 57 is also provided on the rotating shaft 53 in a left-right symmetrical arrangement. The second mounting blocks 57 on both sides are respectively fixedly connected to the corresponding side walls of the bulletproof baffle 55, so as to further strengthen the connection between the rotating shaft 53 and the bulletproof baffle 55.

[0034] When the plate rebounds, in order to facilitate the cleaning of the rebounded plate, the left end of the rotating shaft 53 is movably arranged to pass through the corresponding side fixed block 52, and a connecting block 58 is fixedly provided on the passing end of the rotating shaft 53, and a handle 59 is fixedly provided on the connecting block 58; through the above-mentioned arrangement, the staff can drive the rotating shaft 53 to rotate by holding the handle 59 and pulling the connecting block 58 to rotate, thereby causing the bulletproof baffle 55 to flip upward, so that the discharge port 4 leaks as much as possible. After that, the plate that has rebounded in the discharge port 4 can be cleaned.

[0035] In order to reduce the difficulty of material discharge operation, in this embodiment, a visual processing component 6 and a pressure wheel moving component 7 are also provided on the frame 1. The visual processing component 6 is arranged above the feeding mechanism 2, and the pressure wheel moving component 7 is arranged between the feeding mechanism 2 and the sawing mechanism 3. The wood transported by the feeding mechanism 2 will pass through the visual processing component 6 and the pressure wheel moving component 7 in turn, and then enter the sawing mechanism 3. The visual processing component 6 can identify the size of the wood and then control the pressure wheel moving component 7 to adjust the position of the wood entering the sawing mechanism 3.

[0036] The visual processing component 6 includes an identification box 61, which is arranged on the top surface of the frame 1. The feeding part of the feeding mechanism 2 is arranged to pass through the identification box 61. A camera 62 and a controller 63 are arranged inside the identification box 61. The camera end of the camera 62 is arranged to face the feeding part of the feeding mechanism 2. The controller 63 is electrically connected to the camera 62. The camera 62 can shoot the board passing through the identification box 61 and may send the shot image information to the controller 63. The controller 63 is equipped with an image processing program commonly used in the prior art, and can identify and process the wooden board image shot by the camera 62 to obtain the size information of the wooden board.

[0037] The pressure roller moving assembly 7 includes a fixed frame 71. In this embodiment, there are two fixed frames 71, both of which are arranged on the frame 1. Each fixed frame 71 is provided with a slide rail 72 and a lead screw 73. The layout direction of the slide rail 72 and the lead screw 73 is perpendicular to the feeding direction of the feeding mechanism 2. A sliding frame 74 is provided above each fixed frame 71. The two sliding frames 74 are threadedly connected to the lead screw 73 at the corresponding position. A slider 75 is provided at the bottom of each sliding frame 74. Each slider 75 is slidably connected to the slide rail 72 at the corresponding position. A pressure roller group 76 is also provided on the sliding frame 74. The pressure roller group 76 is a common pressure roller structure in the prior art, which serves to transport wooden boards. The wood transported by the feeding mechanism 2 can pass through the pressure wheel group 76 and then enter the sawing mechanism 3. A drive motor 77 is also provided on the frame 1. The drive motor 77 is transmission-connected to the lead screws 73 on both sides. The drive motor 77 can drive the lead screws 73 on both sides to rotate. The drive motor 77 is also electrically connected to the controller 63.

[0038] Through the above arrangement, during the process of processing a wood board, a worker places the wood board on the feeding mechanism 2, which transports the wood board to the sawing mechanism 3. During the transportation process, the wood board first passes through the visual processing component 6. The camera 62 in the visual processing component 6 can capture the wood board to be processed. The controller 63 in the visual processing component 6, equipped with a common image processing program, can recognize and process the wood board image captured by the camera 62 to obtain the size information of the wood board. After that, the wood board enters the pressure roller group 76 in the pressure roller moving component 7. At this time, the controller 63 starts the drive motor 77 according to the size information of the wood board in accordance with the preset program, so that the drive motor 77 drives the slide 74 to move, so as to adjust the position of the pressure roller group 76, thereby adjusting the position of the wood board input from the feeding mechanism 2 to the pressure roller group 76, so as to adjust the position of the wood board entering the sawing mechanism 3, so that the wood board can achieve the maximum utilization rate when entering the sawing mechanism 3. It should be noted that the control logic of the preset program on the controller 63 can be programmed according to actual conditions and experience, which is a common control method in the prior art.

[0039] In order to prevent the wooden board from rebounding during the processing of the sawing mechanism 3 and damaging the pressure wheel moving assembly 7, in this embodiment, a bulletproof device 8 is also provided between the pressure wheel moving assembly 7 and the sawing mechanism 3. The bulletproof device 8 is a common bulletproof structure in the prior art, such as the upper bulletproof device and the lower bulletproof device disclosed in the utility model patent with Chinese patent authorization announcement number CN214819218U. The wood output from the pressure wheel moving assembly 7 will pass through the bulletproof device 8 and then enter the sawing mechanism 3. The bulletproof device 8 can prevent the wooden board from rebounding and damaging the pressure wheel moving assembly 7 by clamping the wooden board, thereby ensuring the accuracy of the pressure wheel moving assembly 7 when moving and deflecting.

[0040] To facilitate appropriate maintenance of the saw machine in the event of a wood jam, a connecting port 9 is provided on the frame 1 at the location of the sawing mechanism 3. This connecting port 9 connects the sawing mechanism 3 to the outside world. In the event of a jam, the sawing mechanism 3 is open, allowing the operator to remove the jammed wood directly through the connecting port 9. This facilitates maintenance compared to conventional sawing machines with closed cutting positions. Furthermore, to prevent wood chips from flying during the sawing process, a protective cover 11 is hingedly connected to the frame 1 via a hinge 10. The protective cover 11 covers the connecting port 9. The protective cover 11 covers the connecting port 9 during sawing to prevent wood chips from flying outward. In the event of a jam, the operator can open the protective cover 11 and remove the jammed wood through the connecting port 9. In order to facilitate the staff to observe the processing status of the sawing mechanism 3, the protective cover 11 can be made of transparent materials, such as transparent plastic.

[0041] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
