Detailed ways

As shown in Figure 1-12, a cutting bed, especially for negative pressure adsorption cutting bed (vacuum adsorption cutting bed), which can compact fluffy and elastic materials through film coating and suction , so as to facilitate cutting and cutting, improve cutting efficiency and cutting accuracy. The present invention comprises a bed body 1, a support film roller 2 is arranged at one end of the bed body 1, and a lamination roller 3 and a film coating roller 4 are arranged on the bed body 1. The film support roller 2 is used to support the film roll, which usually has a certain unwinding damping, and needs to be unrolled under a certain traction force. The film coating roller 4 is used to drive the unwinding of the film roll on the film support roller 2, which can clamp the end of the film and can move along the bed body to move in the length direction and height direction, that is, Fig. 1 Movement in the left, right and up and down directions, when moving left and right, it mainly acts as a traction on the film roll; when moving up and down, it mainly plays a role in pressing down on the film. The laminating roller 3 is used to press down the film together with the laminating roller 4 after the film reaches a designated position (enough to cover the raw material), so that the film covers the raw material.

Since the laminating roller 4 of the present invention needs to carry out compound movement along the length and height directions of the bed body 1, generally two sets of power drives can be adopted to promote the length and the height, but this method has high cost, poor flexibility, and Temporarily using too much installation space reduces the operating space of the cutting head, which is not conducive to the overall layout. For this reason, the present invention uses a single power for driving, that is, a set of power drives to realize bidirectional compound motion along the length direction and height direction of the bed body 1 .

As shown in Fig. 1, the film coating roller 4 is driven by a traction drive mechanism, and the traction drive mechanism includes a sliding groove 5 arranged on one side of the bed body 1 and extending along the length direction of the bed body 1, and the sliding groove 5 A driving screw 6 is arranged inside, and the driving screw 6 is connected to the traction motor 7 at one end of the bed body 1 , and the traction motor 7 is used as the only driving force source for the coating roller 4 . The traction drive mechanism also includes two sliding blocks 8 that can reciprocate along the sliding groove 5, in order to ensure the compatibility between the sliding block 8 and the sliding groove 5, as shown in Figure 4, the sliding groove 5 can be in the shape of a 匚A side of the sliding block 8 close to the sliding groove 5 is provided with a protruding block 19 matched with the cavity of the sliding groove 5 , and the protruding block 19 is clamped in the sliding groove 5 .

It is especially important that the middle part of the sliding block 8 of the present invention is provided with a threaded sleeve 9 matched with the drive screw 6, and the middle part of the sliding block 8 is provided with a mounting hole 11 penetrating through both sides of the sliding block 8. The installation circular hole 11 is matched with the screw sleeve 9, and the screw sleeve 9 is arranged in the installation circular hole 11. In order to limit the axial position of the screw sleeve 9 in the installation hole 11, the structure of the screw sleeve 9 can be as shown in FIG. As shown in FIG. 3 , the sliding block 8 is located between retaining rings 12 .

The driving screw 6 is passed through the screw sleeve 9 . The sliding block 8 is also provided with a locking assembly, and the locking assembly can realize the switching between the locking state and the unlocking state of the screw sleeve 9 and the sliding block 8 . In the unlocked state, the screw sleeve 9 forms a rotational fit with the sliding block 8 . Gu Ming thought that in the locked state, the two are locked and fixed. There are many specific structural forms for forming the unlocked and locked states, and in the present invention, an example is only given in a relatively simple manner:

As shown in FIGS. 3 and 4 , a U-shaped movable cavity 13 is provided in the sliding block 8 below the mounting hole 11 , and the two sides of the U-shaped movable cavity 13 communicate with the mounting hole 11 in a tangential direction. The locking assembly includes a U-shaped locking card 14 disposed in the movable chamber 13 and an electromagnetic push rod 15 for driving the locking card 14 up and down. When the U-shaped two sides of the locking card 14 are engaged in the gap between the installation hole 11 and the screw sleeve 9, the screw sleeve 9 and the sliding block 8 are switched to a locked state. When the U-shaped side parts of the locking card 14 withdraw from the gap between the installation hole 11 and the screw sleeve 9, the screw sleeve 9 and the sliding block 8 are switched to an unlocked state. The function of the electromagnetic push rod 15 is mainly to push the locking card 14 to move, so as to realize unlocking and locking. The connection form of electromagnetic push rod 15 and locking card 14 can be, as shown in Figure 4, described electromagnetic push rod 15 is installed in the bottom groove of slide block 8 bottoms, and the telescoping end of electromagnetic push rod 15 is downward, And be connected with the connection plate 16 that is positioned at slide block 8 below. A plurality of rod holes are arranged in the sliding block 8 on the peripheral side of the bottom groove, and corresponding connecting rods 17 are perforated in the rod holes.

And the connecting rod 17 is located between the sliding block 8 and the connecting plate 16 and is provided with a pull-back spring 18 . A plurality of connecting rods 17 can further improve the stability of the movement of the locking card 14 . When the telescopic end of the electromagnetic push rod 15 stretches out, it can overcome the elastic force of the pullback spring 18, so that the locking card 14 moves downward to realize unlocking. When the telescopic end of the electromagnetic push rod 15 was retracted, under the elastic force of the pull-back spring 18, the locking clip 14, as shown in Figure 4, was inserted into the gap, and the four wires locked the screw sleeve 9.

In the case where the threaded cooperation between the drive screw 6 and the sliding block 8 is controllable (unlocking/locking), as shown in Figure 1, a support rod 10 is respectively arranged above the two sliding blocks 8 of the present invention, and The upper ends of the support rods 10 are hinged to each other, and the lower ends of the support rods 10 are hinged to the sliding block 8 . The laminating roller 4 is arranged at the hinge center of the upper end of the support rod 10 . During the rotation of the driving screw 6 , the height of the coating roller 4 can be adjusted by changing the distance between the two sliding blocks 8 . Through the synchronous movement of the two sliding blocks 8, the adjustment of the position of the coating roller 4 in the length direction of the bed body 1 is formed.

During use, the end of the film on the supporting film roller 2 is installed on the laminating roller 4, and the film is pulled out from the supporting film roller 2 by using the movement of the laminating roller 4 along the length direction of the bed body 1 and pulled To the position that is enough to cover the tail end of the raw material to be processed; after the laminating roller 4 reaches the position (the state shown in the upper figure in Fig. 2), the laminating roller 4 and the pressing roller 3 press down, and the film is pressed on the raw material, At this moment, the adsorption system carried by the bed body 1 can be started to extract the air between the film and the upper surface of the bed body 1 (the state shown in the lower figure in Fig. 2); It is pressed against the surface of the bed body 1 to facilitate subsequent cutting. Because there is the function of driving locking and driving disengagement (that is, locking and unlocking between the screw sleeve 9 and the sliding block 8) between the sliding block of the traction drive mechanism of the present invention and the driving screw 6, in the process that the driving screw 6 rotates Among them, the sliding block 8 can be independently or synchronously driven to move. When a certain sliding block 8 is driven to move alone, the distance between the sliding blocks 8 can be adjusted, and the support rod 10 on it can be driven to adjust the angle, thereby realizing the adjustment of the height of the coating roller 4. adjustment; when synchronously driving the two sliding blocks 8 to move, since the distance between the two remains unchanged, they jointly drive the upper support bar 10 and the laminating roller 4 to move, so as to realize the position of the laminating roller 4 in the length direction of the bed body 1 adjustment.

Of course, in order to better determine the position of each sliding block 8 on the driving screw 6, as shown in Figures 1 and 3, an infrared distance sensor 20 is arranged on one side of the sliding block 8 of the present invention, and the infrared distance The sensor 20 faces the distance measuring plate 21 arranged at the end of the bed body 1, and the distance measuring plate 21 is an extension plate corresponding to the infrared distance sensor 20 arranged at the end of the bed body 1, and it is used for detecting the distance between the infrared distance sensor 20 and the infrared distance sensor 20. After the infrared signal is emitted, it provides a base for the infrared signal to be emitted. Of course, the infrared distance sensor 20 can also be installed on the distance measuring board 21 to directly measure the distance from the signal emitted by the sliding block 8 .

Simultaneously, because lamination roller 3 of the present invention is compared with lamination roller 4, it is to press down the middle section of film, is to carry out the main component that lamination is pressed down, and the reaction force that it needs to bear is compared with lamination roller bigger.
