This not only affects the normal operation of the production line, but also increases the scrap rate and production costs.

[0004] Difficulty in directional correction: During the veneer processing process, various factors (such as varying raw material dimensions and processing errors) can cause its direction to deviate from the intended direction. Traditional discharging devices often rely on manual operation for directional correction, which is inefficient and prone to errors, making it difficult to meet the needs of modern production lines.

DETAILED DESCRIPTION

[0027] The directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only used with reference to the directions of the drawings. Therefore, the directional terms used are used to illustrate rather than limit the invention of the utility model.

[0028] like Figure 1-3 As shown, a veneer feeding and straightening device comprises a frame 1, on which are mounted a support plate 2 for supporting the veneer, a conveyor belt 3 for driving the veneer to move, and a straightening belt 4 for correcting the direction of the veneer. In this embodiment, the feeding direction is from front to back, i.e. Figure 1From the lower right to the upper left in the figure, the conveyor belt 3 is positioned between the support plate 2 and the straightening belt 4. The straightening belt 4 rotates vertically, while the conveyor belt 3 rotates horizontally. A negative pressure pipe 5 is installed beneath the conveyor belt 3 to provide negative pressure. This pipe 5 can be connected to an external air pump to generate negative pressure. The pipe 5 is equipped with suction holes for absorbing veneer. The combined design of the support plate 2, conveyor belt 3, and straightening belt 4 achieves efficient, stable conveying and directional correction of veneer. The negative pressure pipe 5 and suction holes effectively absorb the veneer, preventing it from slipping or shifting during conveyance, thereby improving the accuracy and efficiency of discharge.

[0029] Furthermore, the length direction of the conveyor belt 3 is parallel to the length direction of the support pad 2, ensuring a smooth transition of the veneer during transportation, reducing friction and damage that may be caused by angle changes, and further improving the quality protection of the veneer.

[0030] Furthermore, an acute angle is formed between the length direction of the straightening belt 4 and the length direction of the conveyor belt 3, and the intersection of their extension lines is located on the discharge side, thereby realizing automatic correction of the veneer direction, reducing the need for manual intervention, and improving the degree of automation of the production line.

[0031] Furthermore, the frame 1 is rotatably connected to a belt shaft 6 through a bearing seat on the front side of the support plate 2. The conveyor belt 3 includes a belt body 31 and a belt roller 32. The belt roller 32 is installed on the belt shaft 6. A synchronous wheel 7 is also installed on the belt shaft 6. The synchronous wheel 7 is arranged on the front side of the support plate 2, so that the veneer can transition smoothly before entering the conveyor belt 3, avoiding damage to the veneer caused by sudden acceleration or deceleration.

[0032] Furthermore, the belt roller 32 is laterally slidably connected to the belt shaft 6, and the frame 1 is provided with a position adjustment component 8 and a guide component 9 for adjusting the distance from the support pad 2. The position adjustment component 8 includes an adjusting screw 81 and a screw seat 82. The adjusting screw 81 is rotatably connected to the frame 1, and the screw seat 82 is threadedly connected to the adjusting screw 81. One side of the straightening belt 4 and the conveyor belt 3 is installed on the screw, and the other side is connected to the guide component 9, so that the position of the straightening belt 4 and the conveyor belt 3 can be flexibly adjusted according to actual needs, thereby enhancing the adaptability and flexibility of the equipment and ensuring the accuracy of veneer transportation.

[0033] Furthermore, the correction belt 4 and the conveyor belt 3 are installed together on the screw seat 82, and the conveyor belt 3 and the correction belt 4 are connected at the back through a bevel gear pair transmission, thereby realizing synchronous movement of the two, ensuring that the veneer can be simultaneously subjected to the dual effects of direction correction and stable transportation during the transportation process, thereby improving the overall work efficiency.

[0034] Furthermore, the guide assembly 9 includes a driven screw 91 and a driven base 92 for installing the straightening belt 4 or the conveyor belt 3. The driven base 92 is threadedly connected to the driven screw 91, making the installation and adjustment of the straightening belt 4 or the conveyor belt 3 more convenient, while also improving the stability and reliability of the equipment.

[0035] Furthermore, an input shaft 10 is installed on the frame 1, and the input shaft 10 is arranged on the bottom side of the support pad 2. The input shaft 10 is connected to the belt shaft 6 through a belt drive. It has a simple structure, is easy to maintain, and can effectively transmit power, thereby ensuring the stable operation of the conveyor belt 3 and the straightening belt 4.

[0036] Furthermore, a rotating wheel 110 is provided at one end of the support pad 2 in the discharge direction. The rotating wheel 110 is provided on both sides of the length direction of the support pad 2, which helps the veneer to transition smoothly when entering the support pad 2, reducing damage or deviation of the veneer that may be caused by excessive impact force.

[0037] Furthermore, the frame 1 includes a base 11, a cantilever cross frame 12 for connecting the base 11 and a diagonal brace 13 for supporting the cantilever cross frame 12. The support pad 2, conveyor belt 3 and straightening belt 4 are installed on the cantilever cross frame 12. The upper end of the diagonal brace 13 is connected to the cantilever cross frame 12, and the lower end is fixedly connected to the base 11, which not only ensures the stability of the equipment, but also facilitates the installation and maintenance of the equipment.
