Description

Technical Field

[0001] The invention relates to the technical field of wood processing, and in particular to a vacuum adsorption automatic board collecting machine. Background Art

[0002] The production of board skins must go through rounding, peeling, screening and stacking in sequence. Screening is to remove the boards that are damaged or undersized during the peeling process. Currently, manual removal is used. The boards run on the conveyor belt, and workers use rake teeth to pick out unqualified boards. Since it is operated during mechanical operation, it is highly dangerous, and the size of the boards is difficult to determine with the naked eye, making screening difficult. The qualified boards after screening need to be stacked neatly. A swing arm is set at the end of the conveyor frame, and the boards swing back and forth along the swing arm for stacking. Since the swing amplitude and the quality of the boards are different each time, the boards are uneven when they fall, and workers need to perform secondary sorting, which is inconvenient to use.

[0003] The patent with the authorization announcement number CN 204957818 U discloses a vacuum adsorption automatic plate collecting machine, which includes a bracket, on which a conveying rack, a blanking rack and a loading rack are arranged in sequence; observation ladders are arranged on both sides of the conveying rack, and induction probes are arranged on the top; the bottom of the blanking rack is connected to the crossbeam arranged on the bracket through an oil top; a waste conveyor belt is arranged below the blanking rack; a support arm connected through a rotating shaft is arranged on the loading rack; the other end of the support arm is connected to the transmission shaft of the pressing belt through a bearing; the back of the loading rack is connected to a group of adsorption racks arranged on the legs; a suction fan is arranged on the top of the adsorption rack, and adsorption holes and a chain driven by gears are arranged below; a group of pressing plates driven by a crank connecting rod are arranged on the inner side of the adsorption rack; the crank connecting rod is driven by the pressing plate motor; a tray arranged on the legs is arranged below the adsorption rack; the tray is connected to the tray motor through a chain; and a probe is arranged on the legs. It effectively solves the technical problems of difficult screening and uneven stacking in the prior art. However, it has the following problems: it detects the plate skin through a row of sensing probes. If the broken parts of the plate skin are close to each other, it is difficult to detect. When unqualified products are detected, it is necessary to change part of the structure of the plate skin conveying path to discharge the unqualified products. After that, the part of the structure needs to be reset to realize the conveyance of the next qualified product. It has high requirements on the control correlation of the plate skin conveying speed and related structures. Summary of the invention

The synchronous rotation of the two longitudinal lead screws 8 in the same direction can make the first sliders 28 on the two ends of the corresponding conveyor belts move synchronously, thereby driving the first conveyor belt 6 and the second conveyor belt 4 to move closer to or away from each other, that is, the distance between the first conveyor belt 6 and the second conveyor belt 4 can be effectively adjusted.

[0036] In this embodiment, if Figure 1 As shown, the first transmission belt structure 11 is located outside the corresponding side transverse frame plate 10, and a first protective plate 12 surrounding the first transmission belt structure 11 is fixed on the outer side of the transverse frame plate 10.

[0040] The specific working principle of the above vacuum adsorption automatic plate collecting machine is:

[0041] According to the target width of the board skin, the distance between the first conveyor belt 6 and the second conveyor belt 4 is adjusted so that the two sides along the edge of the corresponding length of the board skin can just be placed on the first conveyor belt 6 and the second conveyor belt 4 respectively; and according to the target length of the board skin, the distance between the third conveyor belt 22 and the fourth conveyor belt 21 is adjusted so that the two sides along the edge of the corresponding width of the board skin can just be placed on the third conveyor belt 22 and the fourth conveyor belt 21 respectively. Then start the first motor 25, which can drive the longitudinal rotating roller 3 and the transverse rotating roller 20 to rotate at the same time, and can directly drive the longitudinal roller 16 corresponding to the third conveyor belt 22 to rotate, and can effectively drive the other longitudinal rollers 16 and the transverse roller 5 to rotate through the external meshing teeth 26 and the internal meshing teeth 27, that is, effectively drive each conveyor belt to operate; after the wood is peeled by the peeling machine into board skin, it first enters the flattening module to be flattened, and then the flat board skin is sent to the transverse screening component, and the two sides along the edge of the board skin corresponding to the length are respectively mounted on the first conveyor belt 6 and the second conveyor belt 4. If there is a break in the length direction of the board skin, even if the break is close together, the break will fall due to the lack of support from the conveyor belt, thereby driving the multiple parts of the board skin after breaking from the space between the first conveyor belt 6 and the second conveyor belt 4 The boards and skins which have not been disconnected in the length direction are transported to the longitudinal screening component by the first conveyor belt 6 and the second conveyor belt 4 at the same time; the boards and skins which have successfully passed the transverse screening component are finally pushed to the longitudinal screening component, and the two sides along the edges of the corresponding width of the boards and skins are respectively mounted on the third conveyor belt 22 and the fourth conveyor belt 21. If there are breaks in the width direction of the boards and skins, even if the breaks are close to each other, the breaks will fall down due to the lack of support from the conveyor belts, thereby driving the broken parts of the boards and skins to fall into the waste collection area from the gap between the third conveyor belt 22 and the fourth conveyor belt 21, and the third conveyor belt 22 and the fourth conveyor belt 21 at the same time transport the unbroken boards and skins to the stacking module, and the vacuum adsorption component in the stacking module stacks the screened boards neatly.

[0042] From the above content, it can be seen that the present invention stacks qualified boards by adsorption, and can ensure automatic material drop for boards that are close to each other at the broken parts, without changing part of the structure of the board conveying path, is easy to operate, and can be applicable to boards of different specifications.

[0043] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
