41 whole bendings, while the height of corresponding position extension rod 472 is adjusted, so that location hook 45 increases the set for connection ring 44
It connects.
In the present embodiment, under the action of connection ring 44 and location hook 45, the shape of foam-rubber cushion 41 can be adjusted in real time,
To increase the contact area of foam-rubber cushion 41 Yu roll bending 7, cooling area is increased, cooling rate is accelerated；Since location hook 45 is in height
The adjusting for the realization height that can be convenient under the action of degree regulating mechanism 47 can also reduce location hook 45 when not in use
To lowest part, the placement of foam-rubber cushion 41 will not be had an impact；And due to soaking foam-rubber cushion 41 in advance by outlet pipe 463,
The technique that foam-rubber cushion 41 is contacted with roll bending 7 realizes the cooling work to roll bending 7, it is possible to prevente effectively from the waste of aqueous is so as to work
The feeding work for making personnel, reduces the accident rate that staff's reclaiming process is burned, while also improving working efficiency.
In the present embodiment, as shown in figure 4, the one end for being located at outlet pipe 463 in foam-rubber cushion 41 is in closed, and
It is located at array inside foam-rubber cushion 41 in 463 external peripheral surface of outlet pipe and is equipped with multiple miniature apopores 465, i.e., so that aqueous is logical
It crosses miniature apopore 465 to be flowed into foam-rubber cushion 41, reduces aqueous flow, while the contact point with foam-rubber cushion 41 can be increased,
So that aqueous rapidly and uniformly enters in foam-rubber cushion 41, the waste of aqueous is further reduced.
In the present embodiment, as shown in Fig. 2, at this time in 463 external peripheral surface of outlet pipe at 3 top side location of support frame
Equipped with a position-arresting disk 5, and rubber is equipped in the rotation of 3 top surface of support frame and limits closing piece 51；In position-arresting disk 5 and rubber limiting lock
Under the action of block 51, outlet pipe 463 can be made to insert more firm in foam-rubber cushion 41, be not in loosen showing for disengaging
As causing the waste of aqueous.
Embodiment 2: a kind of combination veneer reeling machine, difference from example 1 is that, as it can be seen in figures 5 and 6, propping up at this time
The top of support 3 be hingedly equipped at foam-rubber cushion 41 with the connecting plate 31 disposed in parallel of sliding block 2, in the lower surface of connecting plate 31
Sliding button is embedded with one block of heat sink 32 vertical with connecting plate 31, and heat sink 32 passes through the mobile fast cunning realized in connecting plate 31
Connection is moved, and also is provided with foam-rubber cushion 41 in the one side of support frame 3 in heat sink 32, and be additionally provided on connecting plate 31
Control the fixed position-limit mechanism 33 in 32 position of heat sink.
As shown in fig. 6, position-limit mechanism 33 includes being arranged on connecting plate 31 and prolonging 31 length direction of connecting plate to carry out battle array
The multiple groups of column setting limit groove 332, and limit 332 section of groove is in 3/4ths round shape, are located at upper fixation in heat sink 32
Equipped with connecting spring 331, the separate one end of connecting spring 331 is fixed with limit roll shaft 333, and limits the outer of roll shaft 333
Circumferential surface is coated with rubber pad 334.
Specific embodiment: it under the action of heat sink 32, may be implemented to swing the radiating treatment of 7 reverse side of roll bending
Connecting plate 31 slides at roll bending 7 so that connecting plate 31 is in 2 horizontality of sliding block, control heat sink 32, foam-rubber cushion
After 41 contact with roll bending 7, limit roll shaft 333 is pressed, so that limit roll shaft 333 is inserted in limit groove 332, in rubber pad
Under the action of 334, limit roller axis 333 can be made embedding solid and reliable in limit 332 interpolation of groove, to realize that heat sink 32 exists
The fixation of the position, later under the action of suction pump 462 and outlet pipe 463, foam-rubber cushion 41 on heat sink 32 also can be by
It soaks, so that the reverse side to roll bending 7 carries out heat dissipation work simultaneously, structure is simple, limits reliable operation, easy to operate.
In the present embodiment, as shown in figure 5, being fixed with fixed plate 6 in 2 upper surface of sliding block at this time, fixed plate 6 is close to even
The one side of fishplate bar 31 is fixed with electromagnet 61, when not in use, can since connecting plate 31 is hingedly arranged on support frame 3
So that the structures such as connecting plate 31 are turned to far from upper roller 11, so as to the feeding work to roll bending 7, electromagnet 61 is realized at this time
Suction-operated to connecting plate 31 guarantees the fixation of 31 position of connecting plate.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
