Currently, the particleboard spreading structure is generally a small-format board production equipment with a relatively small width, mainly used for 4-foot and 8-foot boards. To improve production efficiency, the size of the small-format boards can be increased, i.e., producing large-format boards to increase production efficiency several times over. However, there is no suitable spreading equipment for the production of large-format boards, indicating room for improvement. Summary of the Invention

[0005] A further improvement of the present invention, a transverse laying machine for producing ultra-wide and large-format sheet materials, is that the feeding structure includes a feeding section for feeding shavings into a storage silo. The feeding section includes a feeding belt conveyor, one end of which is rotatably connected to the frame, and the other end is located above the middle of the storage silo. A feeding port is provided above the end of the feeding belt conveyor that is rotatably connected to the frame.

The star-shaped transverse rake group includes a rake roller, and multiple fixed plates are provided circumferentially on the rake roller. The length direction of the fixed plates is the same as that of the rake roller. Multiple arc-shaped plates are also provided on the frame. The arc-shaped plates correspond one-to-one with the star-shaped transverse rake group. The arc-shaped plates are located on one side of the rake roller and the fixed plates to prevent wood shavings from scattering into adjacent star-shaped transverse rake groups.

Detailed Implementation

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, a transverse laying machine for producing ultra-wide, large-format sheet materials includes a frame, on which are mounted a feeding structure, a discharging structure 5, a material distribution structure 6, and a laying structure 8; wherein, The feeding structure includes a storage bin 3, which consists of a feeding belt, front and rear sides of the feeding belt, and a bin plate on the side away from the end of the feeding belt. The unloading structure is located on the bin plate near the end of the feeding belt. The feeding belt is horizontally fixed on the frame, which has front and rear bin plates and a left bin plate in the direction shown in the figure. The right side of the feeding belt is used for material discharge. During discharge, the unloading structure installed on the frame is used in conjunction. The unloading structure includes a set of unloading rakes, which includes several unloading rakes. The lower end of the unloading structure faces the middle of the bulk material structure. The several unloading rakes are arranged at an angle at the front end of the feeding belt. The unloading rakes include unloading rake rollers, which have several unloading blades spaced along their length. The unloading blades include circumferentially designed material-distributing ends, which are used to scatter the wood shavings upwards. The feeding end should not be pushed downwards, otherwise the shavings will be pressed tightly onto the belt, and the material will not fall smoothly; the adjacent components of the unloading rake group should not overlap, cross or contact each other, and the rotation direction should be upwards to push the material. The upward force can counteract the gravitational deformation of the rake roller.

[0021] The bulk material structure includes two symmetrically arranged sets of bulk material rakes; each set comprises multiple rakes, with the two symmetrically arranged sets forming a figure-eight pattern. During material distribution, the material is symmetrically distributed to both ends, with the lower end of the unloading structure facing the center of the bulk material structure. A triangular diversion guide array is also located below the bulk material structure to guide the wood shavings to the paving structure. This forcibly divides the wood shavings into multiple sections, each corresponding to an independent lateral directional rake set. The stainless steel mirror panel is resistant to adhesive adhesion, ensuring long-term diversion; the steep angles of the triangles prevent wood shavings from accumulating.

[0022] The paving structure is located directly below the bulk material structure. The paving structure includes transverse paving rake assemblies, which are star-shaped transverse rake assemblies. Each star-shaped transverse rake assembly includes a rake roller 9, with multiple fixed plates 10 circumferentially positioned on the rake roller. The length of the fixed plates is the same as the length of the rake roller. The frame also has multiple curved plates 11, each corresponding to a star-shaped transverse rake assembly. The curved plates are located on one side of the rake roller and fixed plates to prevent wood shavings from scattering onto adjacent star-shaped transverse rake assemblies. The wood shavings are separated within the trough by the curved plates, preventing them from spilling. The high-speed rotation of the transverse rake assemblies causes airflow changes that can disrupt the falling wood shavings; the curved plates also serve to isolate the airflow.

[0023] Furthermore, the feeding structure also includes a feeding section for feeding wood shavings into the storage silo. The feeding section includes a feeding belt conveyor 2, one end of which is rotatably connected to the frame, and the other end is located above the middle of the storage silo. An inlet 1 is located above the end of the feeding belt conveyor rotatably connected to the frame. Specifically, the feeding belt conveyor can be installed within a housing structure. One end of the housing structure has an inlet, and the other end has an outlet. The outlet faces the storage silo. The lower part of the housing at the inlet end is rotatably connected to the frame. The rotatable connection can be, but is not limited to, motor-driven reciprocating rotation.

[0024] The frame is equipped with a hopper sweeping rake group 4, which is located between the loading section and the storage hopper.

[0025] Furthermore, the storage silo is equipped with a replenishment level rotary switch 16 and a full-silo stop switch 15. Two sets of each switch are provided, distributed on the front and rear sides of the conveyor belt within the storage silo. The full-silo stop switch can be a pressure-type switch; when the silo is nearly full, the pressure plate in front of the switch is triggered, shutting down the material preparation process and the oscillating feeding conveyor belt. A rotary replenishment switch is installed on the front side wall of the silo. When there is material in the silo, the switch does not rotate; when there is a shortage, the switch rotates, transmitting a signal to the material preparation process. Due to the excessive width of the silo, to prevent signal errors, it is preferable to have one set of replenishment level rotary switches and one set of full-silo stop rotary switches on each side of the silo.

[0026] Furthermore, the paving structure is laid on the adjusting frame 12, which is vertically slidably connected to the machine frame. The sliding connection method can be, but is not limited to, existing structural forms such as telescopic cylinders and screw drives. To ensure the sliding problem, a guide structure can also be provided on the machine frame. The guide structure can be, but is not limited to, rods, clamps, linear guides, etc.

[0027] The lower part of the frame is also equipped with a billet assembly line 13, and a dynamic shaving scale 14 is also installed at the billet assembly line. The billet assembly line is used to receive shavings from the pavement structure and form billets.

[0028] Furthermore, the overall structure also includes a bending-resistant central suspension, which is vertically arranged to connect the bulk material structure and the paving rake assembly. There can be two sets of the bending-resistant central suspension; one set is connected at one end to the bulk material structure, and the other set is connected at the other end to the paving rake assembly. Specifically, it connects to the rake rollers of the bulk material rake assembly and the paving rake assembly. In this case, the other end of the suspension is connected to the frame. The bending-resistant central suspension includes a connecting rod and a connecting bearing. The rake roller is connected to the inner side of the bearing, and the outer side of the bearing is fixedly connected to the connecting rod and then to the frame. The connection to the frame is detachable, facilitating adjustment to accommodate the adjustment frame. That is, the connecting rod can have multiple connecting holes for subsequent adjustment. Alternatively, when the rake rollers of the bulk material rake assembly and the paving rake assembly are on the same vertical line, only one set of the bending-resistant central suspension can be provided, connecting the bulk material rake roller and the paving rake roller. Specifically, it includes two sets of bearings and a connecting rod structure. The connecting rod structure is telescopically adjustable to accommodate the adjustment frame. The specific choice can be made based on the actual structure.

[0029] Specifically, the discharge dimensions of the storage silos, unloading structures, and paving structures are eight feet or larger. This is used to achieve the production and preparation of ultra-wide sheet materials.

[0030] The working principle of this invention is as follows: After mixing with adhesive, the oriented wood shavings enter the feeding conveyor belt through the inlet and are conveyed into the storage hopper. Because the conveyor belt runs horizontally back and forth, material falls from both the left and right sides of the hopper, resulting in minimal peaks and troughs in the width of the discharge cross-section. When the wood shavings accumulate to a certain height in the hopper, a sweeping rake group moving from front to back flattens the wood shavings, ensuring a flat discharge cross-section. A pressure-type full-hopper stop switch is installed at the tail of the hopper. When the hopper is about to be full, the pressure plate in front of the wood shavings squeeze switch triggers a signal to shut off the backup. The material handling process and the oscillating belt conveyor are as follows: A rotary replenishment switch is installed on the front side wall of the hopper. When there is material in the hopper, the switch does not rotate; when there is a shortage of material, the switch rotates and the signal is transmitted to the material preparation process. Due to the excessive width of the hopper, to prevent signal errors, a set of replenishment level rotary switches and a full hopper stop rotary switch should be installed on both sides of the hopper. When the unloading belt runs, the wood shavings reach the unloading rake group and are lifted upward by the rake teeth, causing the wood shavings to be thrown up and fall from above the rake group. The wood shavings fall on the bulk material rake group, and the figure-eight shaped rake group rotates at high speed, stretching and scattering the wood shavings to the left and right sides. After the wood shavings are dispersed, they fall into the triangular diversion guide array in both length and width directions, forcibly dividing the shavings into multiple segments, each corresponding to an independent transverse directional rake group. The triangular diversion guide array uses a stainless steel mirror panel, which is not easy to adhere to adhesives and can maintain its diversion function for a long time. The steep angle of the triangle makes it difficult for wood shavings to accumulate. The fixing plate of the star-shaped transverse rake group is made of stainless steel mirror panel bent into an L shape. The bottom of the L is evenly distributed on the roller surface, and the top maintains a 3-5mm gap with the arc-shaped partition guide plate. After each V-shaped isolation zone receives the wood shavings, the wood shavings are separated by the arc plate in the V groove, making it difficult for them to spill. After rotating half a revolution, the disordered direction of the wood shavings changes, and the length direction is parallel to the V-shaped groove, lying flat at the bottom of the V-shaped groove. The high-speed rotation of the transverse rake assembly causes airflow changes that disrupt the falling wood shavings, while the curved plate isolates the airflow from the impact. The transverse rake assembly pours the wood shavings onto the billet production line, resulting in a transverse effect during continuous production.

[0031] It is important to note that the speed of the rake assembly should not be too slow, as this will cause the falling wood shavings to form grooves; nor should it be too fast, as the airflow isolated by the curved plate will still dissipate and scatter the wood shavings outside the rake assembly.

[0032] An plexiglass observation window is installed on the side wall of the diversion area to observe whether wood shavings can accumulate and clog the V-groove of the transverse rake group; Each star rake is equipped with an arc-shaped partition guide plate, which not only blocks the airflow caused by the rotation of the star rake, but also locks the star rake isolation zone.

[0033] The drive transmission of the transverse paving machine is designed with a bevel gear structure, which occupies a compact space and is quiet and precise; In order to adjust the height distance between the transverse rake group and the slab, a lifting adjustment device is designed on the frame of the transverse rake group, which is not limited to manual screw adjustment or electric lifting adjustment; and guide devices are designed at the four corners, which are not limited to clamping plates, linear guide rails, linear bearings, etc.

[0034] The adjacent components of the transverse rake assembly do not overlap or contact each other. The rotation direction is horizontal, throwing materials backward. Due to the gravity deformation of the paving, a vertical suspension device is required. In this example, each transverse rake needs to be suspended at the center line using a set of suspension devices with built-in bearings 6216 (or other similar specifications), fastened to the frame above the transverse rake assembly, and have the function of lifting and adjusting to maintain the same height as the transverse rake assembly.

[0035] The area of ​​the dynamic wood shaving scale should be equal to the material feeding area of ​​the transverse rake group. It should provide real-time feedback on weight changes and make fine adjustments to the speed of the feeding belt so that the weight of the wood shavings laid in the transverse direction is equal to the set value in the process order, thus accurately controlling the amount of material. The working height of the dynamic particle scale should be slightly higher than that of the billet assembly line so that the weight of the billet conveyor belt falling on the scale is not affected by the friction of the front and rear frames.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
