In this case, the board feeding machine 1 is an existing conveying equipment and is not described in detail here; the unfolding mechanism 2 comprises a blanking plate A21 connected to the discharge end of the board feeding machine 1, a mounting frame 22 straddling both sides of the blanking plate A21, and a mounting frame 22 arranged on the blanking plate A2 1, a plurality of evenly arranged limit blocks 211 at the bottom, a translation assembly 23 mounted on the mounting frame 22 for horizontally moving the incoming material falling into the limit block 211, the translation assembly 23 includes a power device 24, the power device 24 drives the telescopic mechanism to drive the push plate at the lower end of the telescopic mechanism to move, and each limit block 211 is provided with a sensing button 212 at the upper end. When all the sensing buttons 212 are triggered by the wooden board falling into the limit block 211, the power device 24 drives the telescopic mechanism to perform a telescopic movement; the efficient cleaning mechanism 3 includes a cleaning table 3 6. There are several processing rollers on the cleaning table 36, which are surrounded by baffles 361 on both sides. The processing rollers are connected from top to bottom, and several groups of conveying wheels 362 are arranged on the inner side of the processing rollers. The processing rollers and conveying wheels 362 are designed to make space on the upper and lower surfaces of the conveyed plate 5, so as to facilitate the blowing and brushing operation of the blowing and brushing assembly 33; the area between adjacent processing rollers is provided with a mounting groove, and an air inlet pipe 331 is installed in the mounting groove. The upper end of the air inlet pipe 331 is connected to the air compressor 35. In this example, the air compressor 35 needs to provide a higher air pressure to ensure the blowing airflow speed, enhancing the cleaning effect; the air inlet pipe 331 is provided with air outlets on both sides of the upper and lower sides of the cleaning table 36, each of which is connected to the blowing and brushing assembly 33, and the blowing and brushing assembly 33 includes: a main air duct 332 connected to the air outlet, and a branch air duct 333 extending upstream and downstream is provided at the end of the main air duct 332, and a side air duct 334 extending to both sides is also provided at the end of one of the branch air ducts 333, and a plate edge self-rotating blowing and brushing mechanism 335 is installed at the end of the side air duct 334, and a plate surface self-rotating blowing and brushing mechanism 336 is installed at the end of the branch air duct 333 without the side air duct 334, such as Figure 3As shown in the arrangement; the discharge end of the cleaning table 36 is provided with a blanking plate B34; the stacking and transferring device 4 includes a stacking box 41, the stacking box 41 is placed at the discharge end of the blanking plate B34, and a plurality of layers of pressure-sensing limiting mechanisms are provided in the stacking box 41, and the pressure-sensing limiting mechanisms are composed of a plurality of layers of pressure-sensing limiting elements 44 of equal height embedded in the inner wall of the stacking box 41; each layer of pressure-sensing limiting elements 44 is evenly distributed on the four sides of the inner wall of the stacking box 41, and the pressure-sensing limiting elements 44 include an elastic mechanism A441 fixed to the stacking box 41, and the other end of the elastic mechanism A441 is fixed to the convex head 442, and the elastic mechanism A441 is arranged in a circular groove opened on the inner wall of the stacking box 41 to accommodate the pressure-sensing limiting element 44, and the convex head 442 is also retracted into the circular groove under pressure, and the convex head 442 protrudes from the inner surface of the stacking box 41, and the upper part of the convex head 442 is a flat curved surface 443, which is duckbill-shaped, as shown in FIG. Figure 8 As shown, this shape design is conducive to pressing the protrusion 442 when the plate 5 moves downward. The pressure-sensitive limiting element 44 of each layer can bear the weight of a wooden board. When carrying two wooden boards, the gravity of the two wooden boards will press the pressure-sensitive limiting element 44 into the stacking box 41, and the wooden board at the bottom falls onto the pressure-sensitive limiting element 44 of the next layer, which is equivalent to iteration. Finally, the pressure-sensitive limiting mechanism of each layer carries a plate 5, and there is a certain distance between the plates 5, which will not be damaged by collision and extrusion, and is also convenient for ventilation and drying. Placing the stacking box 41 on the cart 45 is also convenient for its transportation for subsequent processing or packaging.

[0034] Embodiment 2, the improved scheme of the board stacking and conveying device capable of efficiently cleaning wood chips of the present invention is that: the limit stopper 211 is in a cubic shape, and the two sides of the upstream end thereof are trimmed, such as Fig. 9 As shown, the sensing button 212 is arranged in the middle of the upper end surface of the limit block 211, and all the sensing buttons 212 are connected in series and connected to the control circuit of the control device. When the control circuit is connected, the control device drives the power device 24 to run a process to drive the telescopic device to perform a telescopic operation, and pushes the dense plates 5 falling on the limit block 211 to a certain distance, and slides them onto the cleaning table 36 for their respective cleaning work. The control device can use a PLC controller to coordinate the operation of each electrical device according to the set program; the channels separated by the limit block 211 correspond to the processing raceways one by one, so the number of the limit block 211 is one less than the number of the processing raceways.

[0035] Embodiment 3, the improved scheme of the board stacking and conveying device capable of efficiently cleaning wood chips of the present invention is that: a closed cabin 31 is provided above the cleaning table 36, such as Figure 1As shown, dust curtains 32 are provided on the upstream and downstream sides of the closed cabin 31 to prevent dust, and a dust bag 363 is fixed to the cleaning table 36 under each processing roller. The design of the closed cabin 31 in this example can reduce the dust pollution generated by the blowing and brushing assembly 33 during the cleaning process, thereby protecting the production environment and the health of workers.

For example, for the first column of boards 5 on the left side of the feed center axis, it is necessary to push it away from the original conveying position by 5 cm, which means that the spacing between the boards 5 is 10cm, then the second row of plates 5 need to be pushed 15cm away from the original conveying position, the third row of plates 5 need to be pushed 25cm away from the original conveying position, and so on. Since the distance between the position where the telescopic mechanism is installed and the blanking plate A21 is fixed, the trigonometric function can be used to calculate the angle that each push rod 26 should be set at and the maximum extension length of the push rod 26. In this case, the push rod 26 not only needs to drive the push plate to move horizontally to achieve the technical purpose of widening the distance between the plates, but also needs vertical displacement, and the elasticity of the material made by the elastic plate 28 is used to achieve a temporary relative fixed relationship between the push plate and the plate; the lower surface of the elastic plate 28 is provided with an anti-slip convex strip 29 and is parallel to the plane where the blanking plate A21 is located to prevent the push plate and the plate from sliding relative to each other.

At the same time, the air chamber A3352 rotates, and the blown air flow and the rotating bristles clean the sides of the wooden board at the same time; the axial direction of the air chamber A3352 is parallel to the feeding direction; the board edge self-rotating blowing and brushing mechanism 335 designed in this example only needs to input high-pressure airflow to the rotary joint A3351, and can simultaneously realize the processing actions of blowing and rotating bristles, so as to clean the board edge and part of the board surface, without the need for additional electricity, and the cleaning mechanism is more efficient than single brush cleaning or high-pressure airflow blowing.

When the plate is conveyed in the roller, the plate edge is sprayed and brushed by the plate edge self-rotating blowing and brushing mechanism, and the plate surface is sprayed and brushed by the plate surface self-rotating blowing and brushing mechanism, which not only realizes all-round cleaning of all sides of the plate, but also each surface At the same time, a uniquely designed mechanism that can simultaneously blow air and rotate bristles is used for cleaning. Compared with the single cleaning mechanism and incomplete cleaning positions of existing plate cleaning equipment, it has significant technical advantages. After the plate cleaning is completed, the plate slides from the blanking plate B into the stacking box docked with the cleaning table. The stacking box is provided with a movable card connection component that can conveniently realize docking and disconnection with the cleaning table. There are multiple layers of pressure-sensing limit mechanisms inside the stacking box. Each layer of pressure-sensing limit mechanisms can only bear the weight of one plate. When one layer of pressure-sensing limit mechanisms is squeezed by the gravity of two plates, the pressure-sensing limit element will be pressed into the stacking box to place a plate on the next layer, and finally a plate is placed on each layer of pressure-sensing limit mechanisms, and there is a certain distance between the plates, which is conducive to ventilation and protection of the plates from being squeezed or damaged by collision.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
