DETAILED DESCRIPTION

[0029] 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.

[0030] like Figure 1-6As shown, a suction shearing machine, the material is transported from front to back, that is, Figure 1 From the lower right to the upper left, the frame 1 includes a cutting assembly 2 for shearing the veneer. The cutting assembly 2 includes a cutting knife 21, a driving device 22 for driving the cutting knife 21, and a sensor for identifying the veneer. The frame 1 includes:

[0031] The adsorption support assembly 3 is used to absorb the veneer and transport it, and is arranged on both sides of the cutting knife 21;

[0032] The feeding assembly 5 is used to convey the sheared veneer and is arranged in front of the adsorption support assembly 3;

[0033] Among them, the adsorption support component 3 includes a transition plate 31 and an adsorption tube 32. The length directions of the transition plate 31 and the adsorption tube 32 are perpendicular to the axial direction of the conveying roller 4. The adsorption tube 32 is provided with air holes for adsorbing the veneer. The veneer is adsorbed downward through the air holes. The veneer abuts the conveying roller 4 and moves backward under the drive of the conveying roller 4. The veneer is evenly spread on the transition plate 31 while moving, so that the veneer can be transported evenly and smoothly, and the veneer can avoid indentations and losses caused by extrusion; the gap between the two adsorption support components 3 can be used for shearing, providing shearing space, which is convenient for shearing out veneer with higher flatness, and is suitable for thinner veneer.

[0034] Furthermore, a conveying roller 4 and an auxiliary wheel 8 are respectively provided on both sides of the adsorption support assembly 3. A synchronous belt is provided on the conveying roller 4 and the auxiliary wheel 8. The synchronous belt is provided outside the adsorption tube 32, and the upper end surface of the synchronous belt is located on the upper side of the transition plate 31 and the adsorption tube 32. The length direction of the transition plate 31 and the adsorption tube 32 is perpendicular to the axial direction of the conveying roller 4.

[0035] Specifically, the adsorption tube 32 and the transition plate 31 are interlaced and adjacently arranged, forming an "adsorption tube 32-transition plate 31-adsorption tube 32-transition plate 31" connection to make the suction more uniform and the support evenly distributed, and the friction with the transition plate 31 is small, so that the veneer can be transported more smoothly and smoothly.

[0036] Specifically, the adsorption support assembly 3 on the front side of the cutting knife 21 is connected to a loading plate 311 at the front end. The loading plate 311 is fixedly connected to the end of the transition plate 31 and is integrally formed with the transition plate 31. The loading plate 311 is tilted downward, and the veneer will smoothly transition upward under the action of the loading plate 311, and then will be close to the synchronous belt for subsequent transportation.

[0037] Specifically, the conveying roller 4 includes a rotating shaft 41 and a conveying wheel 42 fixedly mounted on the rotating shaft 41. In order to allow the conveying wheel 42 to better contact the veneer, the upper end of the conveying wheel 42 is set higher than the middle of the loading plate 311. In this embodiment, the upper end of the conveying wheel 42 is set slightly higher than the transition plate 31 and uses a gear.

[0038] Specifically, the adsorption support assembly 3 is connected to a secondary pipe 321 at the discharge end. The secondary pipe 321 is connected to the end of the adsorption pipe 32. The secondary pipe 321 is provided with a ventilation secondary hole to improve the suction force.

[0039] Specifically, the width of the auxiliary tube 321 is smaller than that of the adsorption tube 32. A conveying wheel 42 is provided on both sides of the adsorption tube 32, and the two conveying wheels 42 are located on the same side of a transition plate 31, which can increase the contact area between the conveying wheel 42 and the veneer and improve its friction.

[0040] Specifically, the auxiliary pipe 321 extends to the middle of the loading plate 311, and space for arranging the conveying wheel 42 is formed between the outer side of the auxiliary pipe 321 and the left and right side walls of the adsorption tube 32. One conveying pipe corresponds to two conveying wheels 42, and the conveying wheel 42 does not occupy additional space. The auxiliary pipe 321 is located on the side of the vertical axis of symmetry of the rotating shaft 41 close to the adsorption tube 32 and close to the vertical axis of symmetry, so that the suction force can be extended to the conveying wheel 42 part, making the veneer more stable; the auxiliary wheel 8 is arranged on the inner side of the two adsorption support components 3, and the auxiliary wheel 8 has the same arrangement as the conveying wheel 42. The other end of the adsorption tube 32 corresponding to the auxiliary pipe 321 is connected to the inner end pipe, and an opening is also provided on the upper side of the inner end pipe. The auxiliary wheel 8 is arranged on the left and right sides of the inner end pipe as the driven end of the synchronous belt.

[0041] Specifically, the adsorption support assembly 3 on the front side of the cutting knife 21 is provided with a long hole on the transition plate 31, and the transition plate 31 is hinged with a baffle 6 in the long hole and hinged to the middle part of the baffle 6. The lower end of the baffle 6 is connected to a transmission assembly 7 for pushing the lower end of the baffle 6 so that the upper end of the baffle 6 rotates and extends out of the long hole. The transmission assembly 7 includes a pin shaft 72 and a telescopic device 71 installed on the frame 1. A transmission plate 73 is rotatably connected to the pin shaft 72. The lower end of the transmission plate 73 is connected to the output end of the telescopic device 71. The upper end of the transmission plate 73 is hinged with a connecting rod 74. The upper end of the connecting rod 74 is hinged to the lower end of the baffle 6. The telescopic device 71 can push the lower end of the transmission plate 73, and the upper end of the transmission plate 73 flips, driving the connecting rod 74, and the connecting rod 74 in turn pushes the lower end of the baffle 6. The upper end of the baffle 6 flips accordingly, and can be flipped out to block the veneer or flipped back into the long hole to allow the veneer to pass through; the transmission assembly 7 can be set on the lower side, without taking up valuable upper side space.

[0042] Furthermore, the feed assembly 5 includes a support plate 51 for supporting the veneer, a conveyor belt 52 for moving the veneer, and a correction belt 53 for correcting the direction of the veneer. The conveyor belt 52 is arranged between the support plate 51 and the correction belt 53. The rotation axis of the correction belt 53 is vertical, and the rotation axis of the conveyor belt 52 is horizontal. A negative pressure pipe 54 for providing negative pressure is installed under the conveyor belt 52. The negative pressure pipe 54 can be connected to an external air pump to generate negative pressure. The negative pressure pipe 54 is provided with a suction hole for adsorbing the veneer. By combining the design of the support plate 51, the conveyor belt 52, and the correction belt 53, efficient and stable transportation and direction correction of the veneer are achieved. The provision of the negative pressure pipe 54 and the suction hole effectively adsorbs the veneer, preventing it from sliding or deflecting during transportation, thereby improving the accuracy and efficiency of the discharge.

[0043] Specifically, the length direction of the conveyor belt 52 is parallel to the length direction of the support pad 51, which ensures a smooth transition of the veneer during transportation, reduces friction and damage that may be caused by angle changes, and further improves the quality protection of the veneer.

[0044] Specifically, an acute angle is formed between the length direction of the straightening belt 53 and the length direction of the conveyor belt 52, 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.

The conveyor belt 52 includes a belt body 521 and a belt roller 522. The belt roller 522 is installed on the belt shaft 55. A synchronous wheel 56 is also installed on the belt shaft 55. The synchronous wheel 56 is arranged on the front side of the support pad 51, so that the veneer can transition smoothly before entering the conveyor belt 52, avoiding damage to the veneer caused by sudden acceleration or deceleration.

[0046] Specifically, the belt roller 522 is laterally slidably connected to the belt shaft 55, and the frame 1 is provided with a position adjustment component 57 and a guide component 58 for adjusting the distance from the support pad 51. The position adjustment component 57 includes an adjusting screw 571 and a screw seat 572. The adjusting screw 571 is rotatably connected to the frame 1, and the screw seat 572 is threadedly connected to the adjusting screw 571. One side of the straightening belt 53 and the conveyor belt 52 is installed on the screw, and the other side is connected to the guide component 58, so that the position of the straightening belt 53 and the conveyor belt 52 can be flexibly adjusted according to actual needs, thereby enhancing the adaptability and flexibility of the equipment and ensuring the accuracy of veneer transportation.

[0047] Specifically, the correction belt 53 and the conveyor belt 52 are installed together on the screw seat 572, and the conveyor belt 52 and the correction belt 53 are connected at the back through a bevel gear pair, 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.

[0048] Specifically, the guide assembly 58 includes a driven screw 581 and a driven base 582 for installing the guide belt 53 or the conveyor belt 52. The driven base 582 is threadedly connected to the driven screw 581, making the installation and adjustment of the guide belt 53 or the conveyor belt 52 more convenient, while also improving the stability and reliability of the equipment.

[0049] Specifically, an input shaft 59 is installed on the frame 1, and the input shaft 59 is arranged on the bottom side of the support pad 51. The input shaft 59 is connected to the belt shaft 55 through a belt drive. It has a simple structure and is easy to maintain.

[0050] Specifically, a rotating wheel 9 is provided at one end of the support plate 51 in the discharge direction, and the support plate 51 is arranged in front of the conveying roller 4. The rotating wheel 9 is arranged on both sides of the length direction of the support plate 51 and on the rear side of the loading plate 311, which helps the veneer to transition smoothly when entering the support plate 51, reducing damage or displacement of the veneer due to excessive impact force.

[0051] Specifically, 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.
