Description
Technical Field
The invention relates to the field of sponge cutting, in particular to a method for changing the distance between knife belts along with the angle of a knife flywheel.
Background
The sponge is a porous material with good water absorption and can be used for cleaning articles. The foaming agent is generally formed by mixing foaming resin, foaming auxiliary agent and adhesive resin together, the foaming machine is a device for manufacturing sponge, air is introduced into a foaming agent aqueous solution through the stirring action of the foaming machine to be uniformly dispersed, so that the liquid-phase foaming agent and the gas-phase introduced air have as large contact surface as possible and react to form bubbles, thereby forming the sponge. The sponge is a whole after being generated, and sheets with different sizes and specifications need to be cut according to different requirements.
While the sponge cutting machine is inevitably used when the sponge is cut into the sheets, at present, the cutting tools in the cutting equipment used in the existing market mostly adopt a cutting ring to cut and only one sheet can be cut at a time, so the cutting efficiency of the cutting mode is low.
For example, in patent CN107398944A, a cutting method of a sponge cutter is proposed, which comprises the following steps: (1) opening a numerical control computer of the sponge cutting machine, starting control software, inputting parameters and the size of the sponge to be cut, selecting the shape of a cutting route, and automatically calculating the cutting path of the cutter by the control software; (2) placing the sponge to be cut on a conveying belt, and adjusting the position of the sponge; (3) cutting by the cutter according to a cutting path, delaying for waiting until the cutter is twisted, twisting the cutter to a cutting starting angle, twisting an angle, twisting back to the cutting starting angle, delaying for waiting, and starting to cut the next line section; (4) repeating the twisting and cutting of the cutter until the cutting and forming are carried out; (5) and (6) blanking after molding. The advantage is reasonable in design, and simple structure has effectively solved the cutter and has twisted the preceding problem that has the cutter middle part and turn to inadequately, has improved cutting quality.
The sponge cutting method can only cut a piece of sponge sheet from a whole piece of sponge at a time, and the cutting efficiency is not very high.

In the above steps, what is achieved is slicing the sponge mattress in the horizontal direction, if the sponge mattress needs to be cut in the vertical direction, in step S2, the guillotine base 322 needs to be driven by the guillotine motor 323 to rotate, and then the circular knife belt 3 is driven to rotate, so that the cutting edge of the circular knife belt 3 is always kept in the vertical direction, and in steps S3, S5, and S6, when the sponge is cut, the cutting positions of the circular knife belt are all the same positions, and are all positions above the sponge mattress, and the lifting mechanism is not needed to drive the circular knife belt 3 to lift up and down to change different cutting positions, and only after each cutting is completed, the lifting mechanism drives the circular knife belt 3 to move up to reset, and during cutting, the sponge mattress is transported by the transport belt 3 to move to change the cutting position, when the first cutting position of the sponge mattress moves to the position right below the circular knife belt 3, conveyer belt 3 stops to carry, drive 3 downstream in annular sword area by elevating system and cut out required first piece sheet, second piece sheet, and annular sword area 3 upwards resets after the cutting is accomplished, carry sponge mattress to remove by conveyer belt 3 again and stop the removal behind the second cutting position, cut out required third piece sheet by annular sword area 3 downstream again, fourth piece sheet, so relapse, thereby the cutting to sponge mattress has been realized, when vertical cutting, sponge mattress wholly only needs to take 3 times through annular sword, can realize the cutting to whole sponge mattress, it cuts to need not sponge mattress round trip movement.
According to the cutting method, through the cooperation of the sponge cutting machine, when the sponge mattress is cut, the two-knife cutting can be simultaneously carried out on the sponges with the same thickness or different thicknesses by adjusting the overturning of the annular knife belt within the range of 0-90 degrees and the rotation of the cutting edge of the annular knife belt, so that the working efficiency is greatly improved, and the utilization rate of the annular knife belt is improved.
Based on foretell cutting method, when carrying out the horizontal cutting to the sponge mattress, except adopting single sponge cutting machine when cutting, can also adopt the sponge cutting machine that many fonts were arranged to cut, this kind of method is when cutting, according to the thickness of the sheet of the different layers that the sponge mattress need cut, adjust the height and the rotation angle of each sponge cutting machine's annular sword area respectively, when cutting the sponge mattress, only need the sponge to loop through many sponge cutting machines and can accomplish the cutting to the sponge mattress, and do not need the reciprocating motion of sponge mattress, cutting efficiency can be higher like this.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
