It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.
[0016] In order to illustrate the technical solutions of the present application, the following specific examples are used to illustrate the technical solutions of the present application.
[0017] In order to facilitate the description, only parts related to the embodiments of the present application are shown.
[0018] In combination with Figures 1-3As shown, the wood board fixed-length cutting device comprises a machine table 1, the machine table 1 is provided with a top frame 2 upwards, the machine table 1 is provided with a left and right pair of cutting frames 3, wherein the left cutting frame 3 is fixedly installed, and the right cutting frame 3 is slidingly installed, the cutting frame 3 is rotatably provided with a cutting disc 4, the shaft rod of the cutting disc 4 is provided with a driven wheel 5, the cutting frame 3 is provided below with a cutting motor 6 for driving the driven wheel 5 to rotate, the cutting frame 3 is rotatably provided with a front and rear pair of conveying wheels 7, the same pair of conveying wheels 7 is sleeved with a matched conveying belt 8, and the cutting disc 4 is located outside the conveying belt 8, the machine table 1 is provided with a feeding mechanism for driving the two conveying belts 8 to rotate simultaneously, the feeding mechanism comprises a hexagonal shaft 9 rotatably installed on the top frame 2, wherein the front conveying wheels 7 are all installed on the hexagonal shaft 9 through a hexagonal sleeve 10, and the top frame 2 is further provided with a driving motor 11 for driving the hexagonal shaft 9 to rotate.
[0019] The wood pallet is a horizontal platform device for placing goods and products as unit load for assembling, stacking, carrying and transporting. The wood pallet uses wood board as material, and the wood board can be cut according to fixed length by using the cutting device in the processing process.
[0020] As shown in the drawings, Figure 1 The cutting frame 3 is provided with a limiting seat 12. The cutting frame is located between the limiting seat and the cutting disc, which is a wood board feeding position. When the wood board is cut by using the device, first, the two ends of the wood board are placed on the left and right two feeding positions according to the requirements, the two ends of the wood board are exposed to the cutting disc on the same side, and the stop seat is located in the starting position in the drawing. Then, the feeding mechanism simultaneously drives the two conveying belts to slowly rotate forward, and the wood board moves towards the cutting disc. Under the block of the stop seat, the left and right cutting discs simultaneously complete the cutting of the two ends of the wood board, and the cut wood board continues to move forward by a small distance to be discharged from the front end of the machine table. Then, the stop seat continues to rotate with the conveying belt until it returns to the starting position again, the conveying belt stops rotating, and the next wood board is fed to the feeding position by the worker to wait for cutting.
[0021] In the above cutting process of the wood board, the distance between the two cutting discs is the required length of the wood board. After the cutting device completes the cutting of all the wood boards, all the cut wood boards have the same length.
[0022] In the process of cutting the wood board, when the feeding mechanism drives the two conveying belts to rotate forward at the same time, the driving motor starts to work and drives the hexagonal shaft to rotate. Since the two front conveying wheels are installed on the hexagonal shaft through the hexagonal sleeve, when the hexagonal shaft rotates, the two front conveying wheels rotate under the action of the hexagonal sleeve, and the two conveying belts rotate forward.
[0023] As a preferred structure, Figure 3The machine base 1 is provided with a pair of straight racks 13. The right cutting frame 3 is rotatably provided with a rotating shaft 14 below it. The rotating shaft 14 is provided with a pair of gears 15. The gears 15 mesh with the straight racks 13 on the same side. The right cutting frame 3 is also provided with a sliding motor 16 for driving the rotating shaft 14 to rotate.
[0024] The distance between the two cutting discs is the required length of the wooden board, and the right cutting frame is slidably mounted on the machine. In practice, the distance between the two cutting discs can be changed by adjusting the installation distance of the right cutting frame, allowing the wooden board to be cut into different lengths using the two cutting discs.
[0025] When adjusting the installation position of the right cutting frame, the sliding motor first drives the rotating shaft to rotate, and the rotating shaft drives two gears to rotate on the same side of the rack. During the rotation, the right cutting frame slides on the machine platform until the right cutting frame is adjusted to the required position, and then the sliding motor stops working.
[0026] Since the front conveyor wheel is mounted on the hexagonal shaft via a hexagonal sleeve, during the adjustment of the right cutting frame's installation position, the front conveyor wheel on the right cutting frame can move normally on the hexagonal shaft via the hexagonal sleeve, and when the hexagonal shaft rotates, the front conveyor wheel can also rotate along with it via the hexagonal sleeve.
[0027] In the above structure, such as Figure 2 Multiple locking nuts 17 are screwed into both sides of the front conveyor wheel 7. The bottom of the locking nuts 17 passes through the hexagonal sleeve 10 and resists the hexagonal shaft 9. Before adjusting the installation position of the right cutting frame, all locking nuts on the right front conveyor wheel must first be loosened. When all locking nuts no longer resist the hexagonal shaft, the sliding motor can drive the rotating shaft to rotate. Under the drive of the rotating shaft, the gear rotates on the spur rack on the same side. At that time, the front conveyor wheel on the right cutting frame can slide normally on the hexagonal shaft through the hexagonal sleeve. After sliding into place, all locking nuts are tightened.
[0028] In this device, such as Figure 1 The cutting frame 3 has two cutting platforms on its side wall, an inner one marked as 181 and an outer one marked as 182. The outer cutting platform 182 is inclined downwards, and the outer cutting platform 181 has a cutting groove 19, with the cutting disc 4 located in the cutting groove 19.
[0029] When the wooden board is placed on the left and right feeding positions as required, the two ends of the wooden board are located on the cutting tables on both sides. By setting two cutting tables, one inside and one outside, the contact area of the wooden board can be increased, making the wooden board more stable during cutting. On the other hand, after the wooden board is cut, the short pieces of the wooden board can automatically slide off from the outer cutting table on the same side.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
