Description

Technical Field

[0001] The utility model belongs to the relevant technical field of embossing equipment, in particular to a separation membrane nonwoven fabric and an embossing mechanism thereof. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the printing process on the surface of fabrics. At present, embossing machines are generally used to emboss the surface of fabrics. Embossing machines are mainly used to emboss, bubble, wrinkle and trademark on various fabrics. They can also be used to emboss trademarks, simulated leather patterns and various deep and shallow flower patterns on non-woven fabrics, coatings, artificial leather, paper and aluminum plates. Roller knurling is a comprehensive process of cutting and cold pressing. During the knurling process, the outer surface of the workpiece is accompanied by chips while being extruded and plastically deformed. The higher the hardness of the workpiece, the greater the proportion of cutting. It also refers to the processing method of rolling out patterns on the surface of the workpiece with a knurling tool. The head of the knurling tool is equipped with one or two rotatable rollers with patterns engraved on the circumference. When in use, the roller is pressed against the surface of the workpiece and moves relative to it to roll out the pattern.

[0003] For example, patent number 202022000125.8, the patent name is an embossing device, including a supporting base plate, a flange and a working panel, a first cylinder is provided at the upper end of the supporting base plate, and a first bracket is connected above the first cylinder, and a placement plate is fixed on the upper part of the first bracket. The first cylinder of the embossing device can perform telescopic movement between the first bracket and the placement plate, and the placement plate and the motor are tightly fitted. The first cylinder can drive the first bracket to move up and down, so that the embossing height can be adjusted. The motor can rotate between the first rotating shaft and the flange and the second rotating shaft, and the second rotating shaft and the embossing roller are fixed together. The motor can drive the embossing roller to rotate to realize the embossing work. The second cylinder can perform telescopic movement between the push rod and the limit block, and the limit block is connected to the working surface through the sliding groove. The plates can slide between each other, and the limit block can be driven to move by the second cylinder. This structure can realize the rapid disassembly and replacement of the embossing roller, and can position the two sides of the cloth. However, this structure adopts the method of positioning the two sides of the cloth. Although it solves the problem of position offset on both sides of the cloth, it clamps the cloth from both sides. However, considering that the thickness of the cloth is not high, positioning the cloth on both sides is likely to cause the cloth to bulge toward the middle, and ultimately cause the cloth to be uneven during rolling, resulting in unsatisfactory rolling effect, so it needs to be improved.

[0028] As a preferred solution, the adjustment and limiting assembly 17 includes an adjusting screw rod 171, an adjusting plate 172, an arc rod 173, and a clamping block 174. The adjusting screw rod 171 is threadedly connected to the limiting plate 16. The screw portion of the adjusting screw rod 171 is connected to one side of the adjusting plate 172. The top of the adjusting plate 172 is provided with an arc rod 173 through an axial movement. One end of the arc rod 173 is connected to a clamping block 174. The bottom of the clamping block 174 is provided with a wavy protective silicone strip 175. The protective silicone strip 175 is pressed on the top of the fabric.

[0034] The specific working principle of this structure is as follows: It should be noted that the left and right sides of the bracket 1 are open, which is convenient for one end of the cloth to pass through the bracket 1 from the left side and then lay the cloth flat on the upper surface of the positioning plate 2, and the other end of the cloth passes through the right side of the bracket 1, and the embossed cloth is rolled up by the winding device on the right side. When working, the distance between the two adjustment limit components 17 is adjusted according to the cloth width to achieve the cloth from top to bottom and the side at the same time. The bulge in the middle of the cloth avoids affecting the embossing effect and flatness, and at the same time, it can be adjusted according to the thickness of the cloth. The spacing between the positioning plate 2 and the embossing roller 13 above allows the embossing roller 13 to contact and squeeze the fabric on the surface of the positioning plate 2 to perform embossing (printing) operations on the fabric passing through the surface of the embossing roller 13, so that it can perform printing operations on fabrics of different thicknesses, and a high-pressure nozzle 14 is arranged above the embossing roller 13 to spray powder on the embossing roller 13 to achieve color printing. In the later stage, it is only necessary to connect the side feed connector 15 to the pump body, and the other end of the pump body to the discharge bin. In addition, this structure can also adjust the embossing roller 13 with different patterns to achieve quick disassembly of the embossing roller 13. Therefore, this structure avoids the bulge in the middle of the fabric affecting the embossing effect and flatness by limiting the fabric from top to bottom and from the side at the same time, and can perform printing operations on fabrics of different thicknesses.

[0035] Example 2

[0036] See also Figure 5 As shown, an embossing mechanism disclosed in the present embodiment is preferably provided with a silicone sleeve 22 outside the rotating shaft 19 to facilitate fixing and limiting the embossing roller. A limiting disk 21 is arranged on the left side of the silicone sleeve 22, and a sealing plug 24 covering the right side of the silicone sleeve 22 is arranged on the right side of the silicone sleeve 22. The embossing roller 13 described in the present embodiment is sleeved outside the silicone sleeve 22, and the left side of the embossing roller 13 abuts against the side of the limiting disk 21, and the right side of the embossing roller 13 is positioned outside the silicone sleeve 22 by the sealing plug 24, the inside of the silicone sleeve 22 abuts against the outer wall of the rotating shaft 19, and the outer wall of the silicone sleeve 22 abuts against the inside of the embossing roller 13, thereby increasing the friction between the three and preventing the embossing roller 13 from moving at will after being installed on the rotating shaft 19 and affecting the final embossing technology.
