Description

Technical Field

[0001] The utility model relates to the technical field of plate processing machinery, in particular to a plate pressing device for six-sided drilling. Background Art

[0002] In the woodworking industry, the traditional automated six-sided drill will scrape labels when grooving the board. In order to improve the scraping label phenomenon, several spindle pressure plate structures have been improved, but the effect is not ideal. When the upper spindle of the existing six-sided drill for panel furniture is grooving the board, in order to limit the relative position of the board, a corresponding pressure plate structure will be installed on both sides of the spindle. There are three types of pressure plate structures, namely, real pressure type, air blowing floating pressure type, and ball pressure plate type. These three structures will have corresponding defects in the automated connection of panel furniture woodworking machinery. The first real pressure type, during the grooving process, the pressure plate is close to the board and moves relative to the grooving movement direction, so that the convex object (label) on the surface of the board and the edge of the pressure plate are squeezed, and the label is finally squeezed out. The second air blowing floating pressure type is not ideal in actual use. In practice, the air pressure is not that high, and the pressure plate area is not large enough, so the effect is very limited. The third ball pressure plate type has jamming of the ball during long-term use. Or the height of each ball is different due to uneven wear, which results in an increase in the pressure of individual balls on the plate surface. This forces the balls to sink into the plate surface, and the movement of the plate surface causes scratches on the plate surface.

[0003] Aiming at the difficulty of label scraping on the six-sided drill on the panel furniture woodworking machinery line, this utility model patent provides a new plate pressing device, which reasonably plans the mechanism to a certain extent and solves the label scraping problem. It reduces the failure rate of the machine and the proportion of defective plates. It improves the processing efficiency and the quality of the plate surface. Utility Model Content

The six-sided drill is usually provided with a frame, a crossbeam, a main shaft, a conveyor belt and other mechanisms. It is a prior art and will not be described in detail. The front pressing wheel mechanism 100 and the rear pressing wheel mechanism 200 are respectively located in front and behind the main shaft of the six-sided drill, and the plate to be processed is transported to the bottom of the crossbeam through the conveyor belt. The front pressing wheel mechanism 100 and the rear pressing wheel mechanism 200 can press down at the same time to compact the plate, and the main shaft performs groove processing on the compacted plate; the front pressing wheel mechanism 100 includes a first rubber-wrapped roller 110 and first cylinders 120 respectively connected to both ends of the first rubber-wrapped roller 110, the first rubber-wrapped roller 110 is pressed or loosened by simultaneously pushing and pulling the two first cylinders 120, and the rear pressing wheel mechanism 200 includes a second rubber-wrapped roller 210 and a second rubber-wrapped roller 210 respectively connected to the second rubber-wrapped roller The two connecting rods 220 at both ends of the rubber roller 210 are respectively connected to a second cylinder 230. The two second cylinders 230 push and pull the connecting rods 220 at the same time to drive the second rubber roller 210 to press or loosen the plate. The utility model adopts a front pressing wheel mechanism 100 and a rear pressing wheel mechanism 200 with different structures to press the plate at the same time. The pressing plate has high stability and occupies less space, and is suitable for application on various six-sided drills; because the front pressing wheel mechanism 100 and the rear pressing wheel mechanism 200 are connected and fixed to the frame, they are more stable than the pressing plate mechanism fixed on the main shaft. When pressing the plate, the first rubber roller 110 and the second rubber roller 210 can roll. When the main shaft grooves the plate, the first rubber roller 110 and the second rubber roller 210 can roll. Relative to the force of the label on the plate, the roller always exerts a downward extrusion force when passing by, so as to avoid the label on the plate being squeezed off when pressing the plate.

[0025] Furthermore, the rear pressure wheel mechanism 200 is provided with two connecting rod fixing seats 240 connecting the frame and the connecting rod 220 and two cylinder seats 250 connecting the frame and the second cylinder 230. The rear pressure wheel mechanism 200 is connected to the fixed frame through the connecting rod fixing seats 240 and the cylinder seats 250 at the same time, ensuring that the rear pressure wheel mechanism 200 can be stably connected to the frame and that the connecting rod 220 can move stably when driven by the second cylinder 230; one end of the connecting rod 220 can be rotatably connected to the second rubber-coated roller 210, and the other end can be rotatably connected to the piston of the second cylinder 230. The connecting rod 220 is an "L"-shaped structure, so that the second cylinder 230 can be rotated through the connecting rod when working.

A fixed shaft 223 connecting the connecting rod fixing seat 240 and the connecting rod 220 is provided in the first bearing 222. The connection mechanism between the first bearing 222 and the fixed shaft 223 can ensure the stability of the movement of the connecting rod 220 and improve its service life.

[0026] Furthermore, the front pressure wheel mechanism 100 is provided with two frames connected to the six-sided drill and the fixing plate 112 of the first cylinder 120, the two ends of the first rubber-coated roller 110 are respectively connected with roller fixing blocks 111, the cylinder body of the first cylinder 120 is connected to the fixing plate 112, the piston of the first cylinder 120 is connected to the roller fixing block 111, a floating joint 121 is provided between the piston of the first cylinder 120 and the fixing plate 112, a linear bearing 113 is provided on the fixing plate 112, and a guide shaft 114 connected to the linear bearing 113 is provided on the roller fixing block 111.

The floating joint 121 can absorb the irregular movement of the piston to a certain extent and reduce vibration; Figure 1 As shown in the figure, the states of the front pressing wheel mechanism 100 and the rear pressing wheel mechanism 200 are in the initial state, the piston of the first cylinder 120 is in the retracted state, and the piston of the second cylinder 230 is in the pushed-out state. When the plate enters, the first cylinder 120 drives the first rubber-wrapped roller 110 to push out and compact the plate, and the piston of the second cylinder 230 retracts and drives the second rubber-wrapped roller 210 to rotate through the connecting rod 220 to compact the plate. After the plate falls off the two rollers, the first cylinder 120 and the second cylinder 230 return to the initial state.
