Detailed Description

Referring to fig. 1 to 6, the utility model discloses a plastic pallet welding machine, which comprises a bearing seat 10, a pressing seat 20, a sealing ring and a heating device; the bearing seat 10 is used for bearing the lower tray 92; the pressing seat 20 and the bearing seat 10 can approach or move away from each other; the surface of the pressing seat 20 facing the bearing seat 10 is provided with an adsorption hole 40; the suction holes 40 are used to form a negative pressure to suck the upper tray 91 when operating; the sealing ring is wound outside the adsorption hole 40 and is used for sealing and attaching the surface of the upper tray 91; the heating device is used for heating the surface of the lower tray 92 on the bearing seat 10, which faces away from the bearing seat 10, so as to melt the lower tray 92.

On the basis of the structure, when in use, an external vacuum machine is adopted to form negative pressure in the adsorption holes 40; the sealing ring is closely attached to the surface of the upper tray 91, so that the upper tray 91, the pressing seat 20 and the first sealing ring 30 are enclosed to form a sealing space, the adsorption hole 40 is aligned to the surface of the upper tray 91, therefore, the upper tray 91 can be adsorbed when the adsorption hole 40 is under negative pressure, the lower tray 92 is placed on the bearing seat 10 and is heated and melted by a heating device, and the lower tray 92 is back to the surface of the bearing seat 10, and then the pressing seat 20 is close to the bearing seat 10, so that the upper tray 91 and the lower tray 92 can be bonded to obtain a plastic tray finished product, at the moment, the first sealing ring 30 and the like cannot be bonded, and the plastic tray finished product obtained after bonding is favorably taken out.

The heating device can be a heating plate, and the heating plate can move in and out between the pressing base 20 and the bearing base 10.

The surface of the pressing seat 20 facing the bearing seat 10 in this embodiment is provided with a plurality of adsorption areas all located in the first sealing ring 30, and at this time, the adsorption holes 40 are distributed at a plurality of positions on the pressing seat 20, so that the upper suction cup is adsorbed as comprehensively as possible, and the adsorption stability is improved; each adsorption area is provided with an adsorption hole 40 and correspondingly provided with a second sealing ring 50, each second sealing ring 50 surrounds the corresponding adsorption area, a plurality of small adsorption areas are respectively arranged on the surface of the pressing seat 20 facing the bearing seat 10 and are matched with the second sealing rings 50, at the moment, the tray, the pressing seat 20 and the second sealing rings 50 surround a smaller space, and negative pressure is more easily formed in the space to accelerate the adsorption of the upper tray 91; meanwhile, the first and

second seal rings

30 and 50 are used to achieve a double sealing effect.

The pressing base 20 of this embodiment is provided with the first positioning element 60, and the first positioning element 60 can abut against each side of the upper tray 91, so that the upper tray 91 can be positioned, and the first positioning element 60 is prevented from moving.

In order to realize the upper tray 91 suitable for various different sizes, the first positioning member 60 of the present embodiment includes a plurality of first positioning blocks 61, the plurality of first positioning blocks 61 are matched with and correspond to the periphery of the pressing base 20, that is, positioning blocks are correspondingly disposed on each side of the pressing base 20; each of the first positioning blocks 61 is movable in a direction toward or away from the center of the pressure seat 20, and at this time, when the first positioning block 61 is moved in a direction toward the center of the pressure seat 20, the space surrounded by the plurality of first positioning blocks 61 becomes smaller, and the tray is suitable for the upper tray 91 having a relatively small size, and when the first positioning block 61 is moved in a direction away from the center of the pressure seat 20, the space surrounded by the plurality of first positioning blocks 61 becomes larger, and the tray is suitable for the upper tray 91 having a relatively large size.

In the present embodiment, each first positioning block 61 is correspondingly provided with a locking device, and the locking device fixes the first positioning block 61 on the pressing base 20.

Specifically, the locking device comprises a locking screw, an adjusting groove 100 formed on the corresponding first positioning block 61, and a screw hole formed on the pressing seat 20; it is understood that the extending direction of the adjustment groove 100 is parallel to the moving direction of the first positioning block 61; the rod part of the locking screw passes through the adjusting groove 100 and is screwed with the screw hole, so that the first positioning block 61 is fixed on the pressing seat 20 through the head part of the locking screw; thus, the first positioning block 61 can be moved by loosening the locking screw, and the first positioning block 61 is fixed by tightening the locking screw, so that the operation is convenient and fast.

The first sealing ring 30 of the present embodiment is pressed against the pressing base 20 by the first positioning member 60, so that the first sealing ring 30 is mounted by the first positioning member 60, which simplifies the structure.

The first sealing ring 30 is fixed on the first positioning block 61, so that the first sealing ring 30 can be driven to move when the first positioning block 61 moves, and the first sealing ring 30 can be pressed on the pressing seat 20 after the first positioning block 61 is fixed again; here, when the first positioning block 61 is moved outward, the first seal ring 30 may be stretched to some extent, but since the stretching range is within the elastic range of the first seal ring 30, the structure of the first seal ring 30 is not damaged by the stretching.

The second positioning member 70 is disposed on the carrier 10 of this embodiment, and the second positioning member 70 can abut against each side of the lower tray 92, so as to position the lower tray 92 on the carrier 10.
