Its porosity is over 88%, with 1.4 billion micropores per square centimeter and a pore size range of 0.1μm-0.5μm. This film is laminated on various fabrics and substrates using a special process to become a new type of filter material. Bubble point membrane composited on non-woven fabrics is a common material combination, usually used to improve filtration performance and increase product functionality.

[0003] Most of the current composite machines lack effective tension monitoring and adjustment structures during the composite process, resulting in uneven tension of the materials during hot composite, affecting the air permeability and use effect of the membrane. Some composite machines are equipped with manual tension adjustment mechanisms, which require manual tension adjustment, which is inconvenient to operate. At the same time, there are certain errors in manual adjustment, which will have a certain impact on the composite quality of the product. Therefore, a tension adjustment mechanism for a bubble point membrane composite machine is proposed to solve the above problems. Utility Model Content

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0030] Reference Figures 1-6As shown, a tension adjustment mechanism of a bubble point film laminating machine includes a base 1. The upper end of the base 1 is provided with an unwinding mechanism 2, a laminating mechanism 3, a slitting and rewinding mechanism 4 and a waste edge collecting mechanism 5 from left to right, and a tension adjustment module 6 is provided on the inner side of the laminating mechanism 3.

[0031] Furthermore, the composite structure 3 includes two support frames 301 fixedly connected to the upper end of the base 1, and a hot roller 303 and a driven roller 304 are rotatably connected between the two support frames 301 through a mounting seat, and a PTFE film unwinding roller 302 is rotatably connected to the left end of the support frame 301 through a mounting seat.

[0032] Reference Figures 1-8 As shown, the unwinding mechanism 2 includes two first support plates 201 fixedly connected to the upper end of the base 1, and two groups of symmetrically distributed first tension sensors 205 are provided on the inner sides of the two first support plates 201. The measuring ends of the two opposite first tension sensors 205 are rotatably connected to the through-core shaft 204 through the mounting seat, and the side between the two first support plates 201 away from the through-core shaft 204 is rotatably connected to the first non-woven fabric unwinding roller 202 and the second non-woven fabric unwinding roller 203 through the mounting seat.

[0033] Furthermore, the slitting and winding mechanism 4 includes two second support plates 401 fixedly connected to the upper end of the base 1, and the inner sides of the two second support plates 401 are provided with second tension sensors 403, and the measuring ends of the two second tension sensors 403 are rotatably connected to the roller 402 through the mounting seat.

[0034] Furthermore, the tension adjustment module 6 includes two pin shafts 601 rotatably connected to the inner side of the support frame body 301 and two track plates 602 fixedly connected to the inner side of the support frame body 301. The front end of the track plate 602 is penetrated by an adjustment track 603. The internal rotation of the adjustment track 603 is connected to a roller 604. The inner sides of the two rollers 604 are rotatably connected to tension rollers 605 through deep groove ball bearings. The outer surfaces of the two ends of the tension roller 605 are rotatably connected to connecting blocks 606. A hydraulic cylinder 607 is fixedly installed on the outer surface of the pin shaft 601. The output end of the hydraulic cylinder 607 is fixedly connected to the end of the connecting block 606 away from the tension roller 605. The internal movable connection of the adjustment track 603 is limited by a limit assembly 608.

[0035] Furthermore, the first non-woven fabric unwinding roller 202, the second non-woven fabric unwinding roller 203 unwinds and the PTFE film unwinding roller 302 unwinds two rolls of non-woven fabric and one roll of PTFE film respectively. Before the two rolls of non-woven fabric pass around the tension roller 605, they first pass around the two through-core shafts 204 respectively. The composite material first passes around the roller 402 and then is cut. The roller 402 and the through-core shaft 204 can guide and support the transportation of the material. The through-core shaft 204 and the roller 402 serve as the guide points of the material, forming a clear material path between the unwinding mechanism 2 and the slitting and winding mechanism 4. By setting at both ends of the roller 402 and the through-core shaft 204 The tension sensor can monitor the tension on the path. The tension sensor is electrically connected to the external control device and will feed back the detected data to the control device in real time. When the control device detects a change in tension through the data fed back by the tension sensor, it will start the hydraulic cylinder 607, and the hydraulic cylinder 607 will drive the connecting block 606 to move, so that the roller 604 moves along the adjustment track 603, and then the position of the tension roller 605 is adjusted. By adjusting the position of the tension roller 605, the contact surface of the three materials with the hot roller 303 during thermal compounding can be adjusted, and then the tension can be adjusted to ensure that the tension of the materials is uniform before compounding.

[0036] Furthermore, the limiting assembly 608 includes a baffle 6081, a fixing plate 6082 and a plum-shaped fastening screw 6083. The baffle 6081 and the fixing plate 6082 are both provided with threaded holes, and the internal threads of the threaded holes are connected to the plum-shaped fastening screw 6083. The inner sides of the baffle 6081 and the fixing plate 6082 are both in contact with the outer surface of the track plate 602.

[0037] Furthermore, by turning the plum-shaped fastening screw 6083 to increase the gap between the baffle 6081 and the fixed plate 6082, the connection between the baffle 6081 and the fixed plate 6082 can be loosened. At this time, the position of the limit assembly 608 can be moved. When the limit assembly 608 is moved to the appropriate position, tightening the plum-shaped fastening screw 6083 can fix it. The limit assembly 608 can limit the moving range of the roller 604 in the adjustment track 603 to prevent it from exceeding the tension limit that the material can withstand during the adjustment process, causing the material to be stretched or torn.

[0038] Working principle: When in use, two rolls of non-woven fabric and one roll of PTFE membrane are installed on the unwinding rollers in the unwinding mechanism 2 and the compounding mechanism 3 respectively. Then, the initial tension is set by the external control device, and then the compounding machine is started. The non-woven fabric and PTFE membrane begin to unwind. After the non-woven fabric passes through the through-mandrel 204, it passes through the tension roller 605 together with the PTFE membrane and is sent to the hot roller 303 and the driven roller 304 for compounding. During the compounding process, the tension is monitored by the first tension sensor 205 and the second tension sensor 403, and the detected data will be fed back to the external device in real time. The control device of the part, once an abnormality is found, the control device will start the hydraulic cylinder 607, and the hydraulic cylinder 607 will drive the connecting block 606 to move, so that the roller 604 moves along the adjustment track 603, and then adjust the position of the tension roller 605 to optimize the contact between the material and the hot roller 303, to ensure that the material is heated evenly during the compounding process, thereby improving the bonding effect. The compounded material is transported by the roller 402 and cut and wound according to the preset specifications through the slitting and winding mechanism 4. The excess waste will be collected by the waste edge collection mechanism 5.
