TECHNICAL FIELD

[0001] The utility model relates to a membrane machine equipment technical field, concretely relates to a kind of guiding and removing structure for filament membrane edge in non-woven fabric composite process. BACKGROUND

[0002] Membrane machine can prepare composite material with high gloss, wear resistance, waterproof and other properties by coating coating on the surface of flexible substrate (such as non-woven fabric) and cooling and setting. However, non-woven fabric is prone to filament membrane edge at the edge when forming, which can be wound on the composite roller and rubber roller during the composite process of membrane machine, resulting in that the two rollers are not tightly pressed, affecting the composite effect. At the same time, the filament membrane edge may be mixed into the composite roll, reducing the quality of the roll. Therefore, a structure capable of effectively guiding and removing the filament membrane edge is needed to improve the composite quality of the membrane machine. SUMMARY

[0003] To solve the above problems, the utility model aims at providing a non-woven fabric membrane edge guiding and feeding structure, which uses adhesive tape to stick the filament membrane edge and cooperates with a scraping mechanism to remove it, so as to avoid the winding of the membrane edge on the roller body, ensure the tightness of the composite roller and rubber roller, and improve the quality of the composite roll.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a non-woven fabric membrane edge guiding and feeding structure, comprising a rack, a composite roller, a rubber roller and a swing frame are arranged on the rack, the rubber roller is installed at one end of the swing frame, and the other end of the swing frame is driven to swing up and down by a pneumatic cylinder; adhesive tapes are arranged around the two sides of the rubber roller and the composite roller, respectively, the adhesive tapes are high-temperature adhesive tapes with adhesion; annular grooves are formed on the outer periphery of the rubber roller and the composite roller, respectively, and the adhesive tapes are wound in the annular grooves; the outer side of the adhesive tape passes through several aluminum rollers and a tension pulley, the tension pulley is connected with the rack through a swing arm, one end of the swing arm is rotationally connected with the rack through a pivot, and the other end is fixedly connected with the tension pulley; a hand wheel is fixedly arranged on the pivot, and the hand wheel is locked and positioned with the side wall of the rack through a locking bolt; a bracket is fixedly installed on the pivot, a scraping pneumatic cylinder is arranged on the bracket, a spade is fixedly connected with the output shaft of the scraping pneumatic cylinder, and the spade is in contact with the surface of the adhesive tape through the extension of the scraping pneumatic cylinder, for scraping the filament membrane edge stuck by the adhesive tape.

[0005] Further, the adhesive tape is a high-temperature adhesive tape, and the adhesive surface faces the gap between the rubber roller and the composite roller.

[0006] Further, the cross section of the annular groove is arc-shaped, which is adapted and fitted with the outer periphery of the adhesive tape.

[0007] Further, the number of aluminum rollers is two, which are distributed at intervals along the extension direction of the adhesive tape, for supporting the adhesive tape and adjusting the tension thereof.

[0008] Furthermore, the stroke of the scraper cylinder is adjustable to control the contact pressure between the scraper and the wrapping surface.

[0009] The beneficial effects of this invention are as follows: The high-temperature adhesive wrapping tape, positioned around both sides of the composite roller and the rubber roller, effectively adheres to the filamentous film edges of the nonwoven fabric, preventing them from tangling on the composite roller or rubber roller. The tension adjustment mechanism, consisting of a swing arm, handwheel, and locking bolts, allows for flexible adjustment of the wrapping tape tension, ensuring a tight fit between the wrapping tape and the roller body. Furthermore, a scraper driven by a scraper cylinder contacts the wrapping tape surface, promptly removing any filamentous film edges adhering to the tape and ensuring its continuous guiding function. In summary, this invention effectively solves the problem of roller entanglement caused by filamentous film edges, improving the tightness of the bonding between the composite roller and the rubber roller, and enhancing the quality of the composite roll.

Detailed Implementation

[0014] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0015] like Figure 1 , Figure 2 As shown, this embodiment discloses a nonwoven fabric film edge guiding and feeding structure, including a frame 1. A composite roller 2 and a rubber roller 3 are horizontally arranged on the frame 1. The rubber roller 3 is hinged to the frame 1 through a swing frame 4. The lower end of the swing frame 4 is driven by a cylinder 5 to swing up and down to adjust the pressing gap between the rubber roller 3 and the composite roller 2.

[0016] The high-temperature adhesive tape is made of high-temperature adhesive tape, and the adhesive surface faces the gap between the rubber roller 3 and the composite roller 2. The outer periphery of the rubber roller 3 and the composite roller 2 is provided with an annular groove (not shown in the figure), and the cross section of the annular groove is a circular arc. The inner periphery of the high-temperature adhesive tape is embedded in the annular groove and is adapted to fit, so as to ensure that the high-temperature adhesive tape is stably wound on the roller body.

[0017] The outer side of the high-temperature adhesive tape 6 is wound through two aluminum rollers 7 (distributed at intervals along the extension direction of the high-temperature adhesive tape) and a tensioning wheel 8. The tensioning wheel 8 is connected to the rack 1 through a swing arm 9. The upper end of the swing arm 9 is rotatably connected to the rack 1 through a rotating shaft 10, and the lower end is fixedly connected with the tensioning wheel 8. The front end of the rotating shaft 10 is fixedly installed with a hand wheel 11. By rotating the hand wheel 11, the angle of the swing arm 9 can be adjusted, so as to adjust the tensioning force of the tensioning wheel 8 on the high-temperature adhesive tape 6. After the adjustment is completed, the locking bolt 12 is used to pass through the hand wheel 11 and is screwed with the side wall of the rack 1, so as to lock the position of the tensioning wheel 8.

[0018] The middle part of the rotating shaft 10 is also fixedly installed with a bracket 13. The lower end of the bracket 13 is fixedly connected with a scraping air cylinder 14. The output shaft of the scraping air cylinder 14 extends vertically downward and is fixedly connected with a spade 15. The scraping air cylinder 14 can drive the spade 15 to move downward, so that the surface of the spade 15 is in contact with the top surface of the high-temperature adhesive tape 6. When the high-temperature adhesive tape 6 rotates with the roller body, the spade 15 can scrape off the filamentous film edge adhered on the high-temperature adhesive tape 6, so as to avoid the accumulation of the film edge.

[0019] When the non-woven fabric edge filamentous film edge advances to the gap between the rubber roller 3 and the composite roller 2, the high-temperature adhesive tape 6 adheres the filamentous film edge through the adhesive surface and transports the filamentous film edge along the winding direction of the high-temperature adhesive tape 6. When the high-temperature adhesive tape 6 runs below the scraping air cylinder 14, the spade 15 is in contact with the high-temperature adhesive tape 6 under the driving of the scraping air cylinder 14, so as to scrape off the film edge from the high-temperature adhesive tape 6, and the guiding and cleaning process of the film edge is completed. In this process, the tensioning adjustment of the tensioning wheel 8 can ensure that the high-temperature adhesive tape 6 is closely attached to the roller body, so as to avoid the missing adhesion of the film edge. The temperature resistance of the high-temperature adhesive tape can prevent the failure of the high-temperature adhesive tape due to the too high working temperature of the film coating machine.

[0020] The above technical scheme can achieve the following technical effects: the high-temperature adhesive tape arranged on both sides of the composite roller and the rubber roller can effectively adhere the filamentous film edge of the non-woven fabric edge, so as to avoid the winding of the film edge on the composite roller or the rubber roller. The tensioning adjustment mechanism composed of the swing arm, the hand wheel and the locking bolt can flexibly adjust the tensioning degree of the high-temperature adhesive tape, so as to ensure that the high-temperature adhesive tape is closely attached to the roller body. The spade driven by the scraping air cylinder can timely clean the filamentous film edge adhered on the high-temperature adhesive tape, so as to ensure the continuous guiding function of the high-temperature adhesive tape. In summary, the present application effectively solves the problem of the winding of the roller body caused by the filamentous film edge, improves the pressing tightness of the composite roller and the rubber roller and the quality of the composite roll.
