In the drawings, the shape or thickness of the embodiments can be enlarged, and simplified or convenient markings can be used. Furthermore, parts of each structure in the drawings will be described separately. It should be noted that the elements not shown in the drawings or not described in words are in the forms known to those of ordinary skill in the art.

[0031] Any reference to directions and orientations in the description of the embodiments herein is only for the convenience of description and should not be construed as any limitation to the protection scope of the present utility model. The following description of the preferred implementation modes involves combinations of features, and these features may exist independently or in combination. The present utility model is not particularly limited to the preferred implementation modes. The scope of the present utility model is defined by the claims.

[0032] As Figures 1 to 4 shown, the board sawing production line in the solution of this embodiment includes a vertical saw production line, a transfer area, and a cross saw production line connected in sequence through tracks;

[0033] At least two cross saw production lines are arranged in parallel on both sides of the vertical saw production line. Any cross saw production line is connected to the vertical saw production line through the transfer area, and the transfer area is configured with board stack turning roller tables.

[0034] By designing parallel cross saw production lines and vertical saw production lines and the transfer area connecting the production lines, the expandability of the production line is improved. The parallel vertical saw production lines and cross saw production lines have less requirements for the plant space when the factory expands production and adds new production lines and equipment.

[0035] The connection mode between the cross saw production line and the vertical saw production line is Figure 1For example, the boards sawn by the vertical saw in the vertical saw production line are distributed to both sides through the first board discharging lifting table 6 and the second board discharging lifting table 7. Taking one side as an example, the boards are conveyed to the first stack turning roller table 10 and the second stack turning roller table 12 through the stack transition roller table 8 and the stack transition roller table 9, and then the boards are conveyed to the cross-cut saw production line. In this embodiment, two cross-cut saw production lines are provided. If more cross-cut saw production lines need to be set up, according to the on-site situation, more board discharging lifting tables can be selected to be set up after the first board discharging lifting table 6 and the second board discharging lifting table 7. Each board discharging lifting table can correspond to one production line on each of the left and right sides. By using the height difference, the overlap of the board transportation path can be avoided. It is also possible to set up a transfer area and a cross-cut saw production line on the side of the first stack turning roller table 10 and the second stack turning roller table 12 away from the vertical saw production line, and the connection point can also be selected according to the situation. In this solution, the equipment passed through is specifically set according to the board transfer route.

[0036] In this embodiment, the number of cross-cut saw production lines is two, as Figure 1 shown, symmetrically arranged on both sides of the vertical saw production line.

[0037] In this embodiment, a design scheme of one vertical saw and two cross-cut saws is adopted, which realizes the maximum utilization of the production capacity of the sanding line, further improves the production capacity of the sanding and sawing line, and meets the supporting requirements of the large-capacity continuous press production line.

[0038] In the solution of this embodiment, the vertical saw area includes a vertical saw centering roller table 1, a vertical saw 2, a vertical saw discharging machine 3, a vertical saw board splitting inclined roller table 4, a stacker 5, a first board discharging lifting table 6, and a second board discharging lifting table 7, which are sequentially connected by tracks. The stacker 5 is a two-stack position stacker.

[0039] The main function of the vertical saw board splitting inclined roller table 4 is to receive two boards sawn into the same width by the vertical saw 2, separate the two sawn boards to both sides and make them lean against each other respectively, and then send them into the stacker for stacking.

[0040] The main function of the vertical saw centering roller table 1 is to receive a single board conveyed from the sanding line or the previous station, and then convey it into the vertical saw 2, and ensure that the single board entering the vertical saw is centered and aligned.

[0041] The stacker has two stack positions. Through the cooperation of the stacker 5 with the first board discharging lifting table 6 and the second board discharging lifting table 7, the functions of non-stop two-stack position switching stacking and single-stack position pushing board are realized. It can be Figure 3 seen that the board discharging lifting table can discharge boards in both the left and right directions. According to the sawing conditions of the two cross-cut saws and the waiting conditions of the board stacks to be sawn in front of them, it can be selected which direction to discharge the boards.

[0042] In the scheme of this embodiment, the transfer area includes: a plate stack transition roller station 8, a plate stack transition roller station 9, a plate stack transition roller station 19, a plate stack transition roller station 20, a first plate stack turning roller station 10, a first plate stack turning roller station 10, a second plate stack turning roller station 12, a second plate stack turning roller station 23, a transition roller station 11, and a transition roller station 22;

[0043] The first plate stack turning roller table 10, the transition roller table 11, the second plate stack turning roller table 12, and the cross-cutting production line are connected in sequence through rails.

[0044] The first board stack turning roller table 10 is connected to the first board discharge lifting platform 6 of the longitudinal sawing area through the board stack transition roller table 8, and the second board stack turning roller table 12 is connected to the second board discharge lifting platform 7 of the longitudinal sawing area through the board stack transition roller table 9.

[0045] In this scheme, there are four plate stack transition rollers and four plate stack turning rollers, namely: plate stack transition roller 8, plate stack transition roller 9, plate stack transition roller 19, plate stack transition roller 20, plate stack turning roller 10, plate stack turning roller 12, plate stack turning roller 21, and plate stack turning roller 23. In addition to being used for receiving, turning and conveying plate stacks, the above machines can also be used to store plate stacks to be sawed. A total of 8 plate stacks to be sawed can be stored, which can enable the two sets of cross saws to work fully and effectively, thereby maximizing the production capacity of the sanding line.

[0046] like Figure 3 As shown, in this embodiment, two shorter transfer routes and two longer board transfer routes are designed, and 8 machines that can store board stacks are also set up along the way. This arrangement can accurately distribute and store the boards processed by the longitudinal saw.

[0047] Taking one side as an example, the horizontal saw production line includes a horizontal saw feeder 13, a horizontal saw 14, a horizontal saw unloader 15, a horizontal saw board discharger 16, a board discharge stacker 17, and a board discharge lifting platform 18, which are connected in sequence through rails. The longitudinal saw 2 is a split longitudinal saw, and the horizontal saw 14 is a flexible saw.

[0048] In this embodiment, the longitudinal saw 2 is a split longitudinal saw, which has the following characteristics: the middle saw is fixed and used to saw the board width into two equal parts, and the saws on both sides can be fine-tuned and used to saw the board edge strips; the transverse saw 14 and the transverse saw 25 are flexible transverse saws to achieve flexible sawing; 5-6 feet wide boards are also cut by the transverse saw 14 and the transverse saw 25.

[0049] In this embodiment, the longitudinal sawing production line is arranged at the end of the sanding production line, and the end of the transverse sawing production line is provided with a board inspection and packaging production line.

[0050] In this embodiment, the process flow of the plate sawing production line of the utility model is as follows: Figure 3 , Figure 4As shown in the figure: The board processed by the sanding line is sent into the production line of this embodiment. The board first passes through the longitudinal saw alignment roller table 1. The function of the longitudinal saw alignment roller table 1 is to align and center the single board sent. Then it is conveyed into the longitudinal saw 2. The longitudinal saw 2 is responsible for separating the wide board in the middle and sawing the edge strips. Then the longitudinal saw discharge machine 3 transports the sawn board to the longitudinal saw board splitting inclined roller table 4 and processes the waste sawn off. The longitudinal saw board splitting inclined roller table 4 separates the two sawn boards to both sides and aligns them respectively, and then sends them into the stacker 5 to stack the boards into a board stack. Then it is conveyed to the first board discharging lifting table 6 and the second board discharging lifting table 7. The first board discharging lifting table 6 and the second board discharging lifting table 7 distribute the board stack to the left and right. Since the left and right transfer areas and the cross saw production line are symmetrical in this embodiment, one side is taken as an example for description. The first board discharging lifting table 6 will transfer the board stack to the first board stack turning roller table 10 through the board stack transition roller table 8. The board stack adjusts its direction on the first board stack turning roller table 10, and then is transferred to the second board stack turning roller table 12 through the transition roller table 11. At this time, the second board stack turning roller table will not adjust the orientation of the board stack again. The second board discharging lifting table 7 directly transfers the board stack to the second board stack turning roller table 12 through the board stack transition roller table 9. In this route, the second board stack turning roller table 12 will adjust the orientation of the board stack. The second board stack turning roller table 12 transfers the board stack to the cross saw feeder 13 (for the symmetrical other cross saw area, it is the cross saw feeder 24). The cross saw feeder 13 selects an appropriate number of boards and sends them into the cross saw 14 for sawing. The boards sawn by the cross saw 14 are sent into the cross saw unloading machine 15 (for the symmetrical other cross saw area, it is sent through the cross saw unloading machine 26) and into the cross saw discharging machine 16 (for the symmetrical other cross saw area, it is sent into the cross saw discharging machine 27). After aligning the positions of the boards, the cross saw discharging machine 16 sends the boards into the unloading board stacker 17 (for the symmetrical other cross saw area, it is sent into the cross saw discharging machine 28). The unloading board stacker 17 stacks the boards and sends them into the board discharging lifting table 18 (similarly, for the symmetrical other cross saw area, it is sent into the board discharging lifting table 29). The board discharging lifting table 18 cooperates with equipment such as forklifts or conveyor belts to transport the boards to the finished product warehouse or the board inspection and packing line.

[0051] The purpose of the present utility model is to provide a design scheme for a board sawing production line with a large width and super large production capacity aiming at the current market demand for large production capacity and large width. The board sawing production line in this scheme meets the development needs of high speed, wide width and large production capacity in the wood-based panel industry, and is applied to the sawing production line section of the large production capacity sand saw line in the wood-based panel industry, especially for boards with a width of 8 - 9 feet and a daily production capacity of 2500m 3 The above-mentioned sawing production line section of the super large production capacity sand saw line is used to saw the large-sized board blanks produced by the continuous press into finished boards of various specifications.

[0052] A sheet sawing production line of the present utility model was tested for transformation in a certain sand saw line production line in Hong'an, Hubei. Before the transformation, the production capacity was relatively low. After the application of this solution, the sand saw line production line produced boards normally. The width of the rough boards was 8 feet, and the production capacity was 2,750 m per day. 3 While the production capacity has been greatly improved, the operation of the production line is also smoother than before the transformation, significantly reducing the frequency of manual intervention in the operation of the production line. This project verified the production capacity of the production line designed by the present utility model.

[0053] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments.
