Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of edge banding machines, in particular to a narrow plate circulating edge banding device. BACKGROUND

[0002] Edge banding is an important process in the manufacturing process of plate furniture, and the quality of edge banding directly affects the quality, price and shelf life of the product. When the side of the plate is edge banded in the plate furniture production and wood product factory, the plate with a large length-width ratio or the relatively narrow plate will be encountered, which is commonly known as narrow plate. These plates may have the following problems during feeding:

[0003] (1) The plate is prone to deviation, especially when the short edge of the plate is edge banded, the pressing area is too small, and the plate is prone to deviation and tilt during feeding, which cannot be fed into the edge banding machine in a parallel state, resulting in large deviation of the edge banding machine processing reference.

[0004] (2) If the size deviation of the cut plate exceeds a certain range, the diagonal dimension of the plate after pre-milling will have an error problem.

[0005] (3) The plate with a large length-width ratio cannot be closely edge banded into the edge banding machine, which cannot be accurately positioned, resulting in the edge banding material not being able to edge band the plate, and the plate not being edge banded. When the edge banding material is not edge banded, the edge banding material will accumulate in the equipment, causing the edge banding material to be stuck in the equipment.

[0006] (4) Manual feeding is not easy, and the feeding degree of the plate is relatively weak, resulting in low feeding efficiency, poor edge banding quality, unstable product quality, high scrap rate, and high production cost.

[0007] In addition, most of the current equipment uses left and right edge banding machines connected in line, which can only edge band 2 sides at a time, and the efficiency is low and repeated to solve the problem of 4 side edge banding. Although there are 4 edge banding machine narrow edge rotating line devices, which can complete 4 side edge banding at a time, most of them cannot meet the edge banding requirements of narrow plates and large size plates, and are limited to edge banding the short side first and then the long side, or edge banding the long side first and then the short side, cannot meet the demand of arbitrary edge switching edge banding, and occupy space, high cost.

Preferably, the pushing hand stopper 2412 has an L-shaped structure, the plate member is positioned by the L-shaped structure, thereby stably pushing the plate member. The pushing hand assembly 241 is driven to move by the pushing hand driving assembly 242, since there is a certain delay time after the pushing hand mechanism 24 responds to the signal of the second sensor 27, therefore, the speed of the pushing hand driving assembly 242 driving the pushing hand assembly 241 is greater than the conveying speed of the conveying mechanism 21, so as to ensure that the pushing hand assembly 241 can catch up with the plate member; it can be understood that when the first sensor 26 detects that the plate member passes, the pushing hand assembly 241 is located below the conveying mechanism 21, so that the plate member can be conveyed on the conveying mechanism 21, then the pushing hand cylinder 2411 drives the pushing hand swing arm 2413 to swing, and then the pushing hand stopper 2412 extends above the conveying mechanism 21, so as to clamp the plate member in cooperation with the stopping mechanism 25.

[0070] In addition, the stopper connecting shaft 2514 is arranged on the stopper fixing seat 2512, and one end of the stopper swing arm 2515 is rotationally connected with the stopper connecting shaft 2514.

When the compression amount of the buffer cylinder 2511 reaches a preset value, the buffer cylinder 2511 sends a signal to the control system, indicating that the stopper mechanism 25 and the push hand mechanism 24 have clamped the plate. It can be understood that if the compression amount of the buffer cylinder 2511 exceeds the preset value, it indicates that the stopper mechanism 25 and the push hand mechanism 24 clamp the plate too tightly, and the control system will generate an alarm signal.

Meanwhile, the plate is positioned by the side auxiliary aligning mechanism 12, the plate is conveyed along the reference of the side auxiliary aligning mechanism 12, and the conveying fluency is improved; the turning connecting shaft 134 is driven to rotate by the turning cylinder 132, the guide plate 136 is swung left and right, and the posture of the plate on the inclined roller 111 is straightened by the guide plate 136; when the plate is inclined, the plate is pushed by the swinging guide plate 136, so that the long side or the short side of the plate is perpendicular to the guide plate 136, then the plate is vertically oriented to the side auxiliary aligning mechanism 12, the long side or the short side of the plate which needs to be edge sealed completely abuts against the side auxiliary aligning mechanism 12, and then the plate is fed into the auxiliary conveying device 20 along the side auxiliary aligning mechanism 12, and the feeding of the plate is completed.
