Example 2:
the working principle of the equipment for hot pressing the plane screen cloth on the surface of the curved surface product and profiling die cutting is as follows:
1. the laser sensor is used for detecting whether the lower jig is used for placing a product or not, and the pressure difference between the lower movable plate 417 and the cloth supporting plate 418 clamps the mesh 419 and moves downwards to tension the mesh 419 without creasing.
2. The hot melt adhesive has been sprayed in advance on the product surface, and the heat that heats up of hot pressing tool 44 passes through the silica gel cover (protection screen cloth effect) and transmits the screen cloth back of being heated, and screen cloth 419 hugs closely on the product surface this moment, can make the hot melt adhesive on product surface melt and bond together with screen cloth 419.
3. As the process requires that the mesh 419 on the front and rear sides maintains straight and regular lines, the front and rear sides of the mesh 419 have no stretching amount, and the left and right sides have larger stretching amount, but the stretching of the left and right sides when the mesh 419 is tensioned can affect the line deformation and irregular phenomenon of the mesh on the front and rear sides. Therefore, when the cloth clamping is designed, the front surface and the rear surface are provided with mesh cloth releasing and four-corner anti-buckling eliminating technology, and the mesh cloth grain rule and the size uniformity are ensured.
4. The mesh cloth 419 is shaped to a specified shape required by die cutting by using a die cutting board (the die cutting board is arranged at the upper end of the profiling die cutter 410, and the length and the width of the die cutting board are both smaller than the length and the width of the profiling die cutter 410), and then the profiling die cutter 410 is driven by an oil cylinder 412 to cut off redundant auxiliary mesh cloth.
5. And finishing wrapping the product and taking out the product.
Example 3:
the equipment for hot pressing the plane mesh on the surface of a curved product and profiling and die cutting solves the problems that the edge of the laser cutting mesh is yellow and has poor appearance, smoke and odor generated by laser cutting pollute the atmosphere and influence the breathing health of operators. The tooling jig, the conveyor belt and the laser cutting equipment are reduced, the power consumption is reduced, the environment is protected, the energy is saved, and the operating personnel are reduced. The multi-layer independent action structure is adopted to reduce the occupied area and space, the cloth supporting plate 418 is adopted to lay the mesh cloth flat, the pressure difference between the lower layer movable plate 417 (large pressure) and the cloth supporting plate 418 (small pressure) is utilized to clamp the mesh cloth and move downwards to tension the mesh cloth without folding, at the moment, the hot pressing jig downwards compresses the product, the set time is kept for about 12-17 seconds (the time required by activation of hot melt adhesive), the set temperature is about 70-110 ℃ (the temperature required by activation of the hot melt adhesive), and then the oil hydraulic cylinder 412 drives the profiling die cutter 410 to move upwards to complete the cloth cutting action.
Example 4:
the frame 12 of the equipment for hot pressing the plane mesh cloth on the surface of a curved surface product and profiling die cutting is a supporting part, and four corners of the bottom of the equipment are provided with universal casters and foot cups, which are convenient for moving and fixing the equipment.
Example 5:
FIG. 7 is a flow chart of the operation of the apparatus for heat pressing a flat web to the surface of a curved product and profiling die cutting in accordance with the present invention.
Step one, a product is placed on the lower die jig 11, the product is placed on the lower die jig 11, whether the product is placed is checked, and the laser detection device detects that the double-start button can be activated to use after the product is placed.
And step two, placing the mesh cloth 419 on the cloth supporting plate 418, pressing the starting button with two hands for the first time, moving the cloth supporting plate 418 upwards to a limited position, and placing the mesh cloth 419 to the limited position.
And thirdly, the lower movable plate 417 presses the cloth supporting plate 418 downwards, and the lower movable plate 417 clamps the mesh 419 downwards after the start button is pressed by two hands for the second time (the mesh 419 clamps the lower movable plate 417 by using the reverse force of the cloth supporting plate 418 and continuously moves downwards to counteract the reaction force of the cloth supporting plate 418 so as to tightly attach the mesh 419 to the outer surface of the product without folds).
And step four, pressing the upper die mechanism downwards to start hot pressing, moving the upper movable plate 416 downwards to start hot pressing and wrapping the cloth after the cylinder connected with the lower movable plate 417 detects the position, keeping the set time and finishing the mesh cloth into the shape required by die cutting.
And step five, the die-cutting locking forcing structure 46 acts, and the die-cutting locking forcing structure 46 prevents the die-cutting force from being overlarge to jack the upper movable plate 416 upwards.
And step six, driving the profiling die-cutting rule 410 to move upwards by an oil hydraulic cylinder 412 so as to cut off the redundant auxiliary mesh.
And step seven, the cloth supporting plate 418 is reset downwards, and the cloth supporting plate 418 is reset downwards so as to be convenient for taking out the product and placing the next product.
And step eight, the upper movable plate 416 resets upwards, and the upper movable plate 416 resets upwards to release the product.
And step nine, the lower movable plate 417 resets upwards, and the lower movable plate 417 resets upwards to leave enough space for an operator to take and place products.
And step ten, taking out the product and the redundant screen cloth, and manually taking out the product and the auxiliary screen cloth after the working procedure is finished.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent processes performed by the present invention or directly or indirectly applied to other related technical fields are also included in the scope of the present invention.
