Description

Technical Field

[0001] The utility model relates to the technical field of meltblown nonwoven fabric processing, in particular to a multi-point hot pressing mechanism for elastic meltblown nonwoven fabric. Background Art

[0002] Elastic meltblown non-woven fabric is a multi-layer non-woven fabric that is widely used in people's lives. During the processing of meltblown non-woven fabric, a hot pressing mechanism is required to perform hot pressing treatment on the multi-layer non-woven fabric structure.

[0003] The existing technical authorization announcement patent document CN218112004U provides a multi-point hot pressing mechanism for meltblown non-woven fabrics for cleaning dirt. When the meltblown non-woven fabric becomes loose, the multi-point hot pressing mechanism for meltblown non-woven fabrics for cleaning dirt utilizes the elastic force of the fixed spring to make the tensioning frame rise and drive the tensioning roller to rise, thereby tensioning the meltblown non-woven fabric. When the meltblown non-woven fabric is too tight, the tensioning roller will continue to be pressed down and the fixed spring will be compressed, thereby utilizing the elastic force of the fixed spring to automatically adjust the tension of the meltblown non-woven fabric, thereby improving its practicality.

[0004] However, the existing multi-point hot pressing mechanism for elastic meltblown non-woven fabrics is not convenient for removing impurities from the hot-pressed non-woven fabrics during use. During the processing of the non-woven fabrics, static electricity will cause a large amount of dust and debris to adhere to their surface. If the non-woven fabrics are directly hot-pressed without being cleaned, the quality of the finished non-woven fabrics will be directly affected, which is not convenient for meeting the production needs of enterprises.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Please refer to Figure 1 Figure 4 The utility model provides a kind of technical solutions: a kind of multi-point type hot press mechanism for elastic melt-blown nonwoven fabric, including support frame 1, the side of support frame 1 is fixedly connected with support box 2, hot press roller group 3 is provided on the side of support box 2 away from support frame 1, the inside of support box 2 is provided with impurity removal mechanism 4, the inside of support frame 1 is provided with tensioning mechanism 5, the outside of hot press roller group 3 is provided with supporting mechanism 6;

[0026] ​The impurity removal mechanism 4 includes an ion fan 401, which is fixedly installed on the upper surface of the support box 2. The bottom end of the ion fan 401 passes through the support box 2 and is fixedly connected to an air outlet pipe 402. The interior of the support box 2 is fixedly connected to a hollow partition 403. The outer surface of the support box 2 is fixedly connected to a filter plate 404. The side of the filter plate 404 away from the support box 2 is fixedly connected to a suction fan 405. The tensioned non-woven fabric enters through the slot on the side of the support box 2. The ion fan 401 removes static electricity from the processed non-woven fabric and blows off dust and debris on the surface of the non-woven fabric. The suction fan 405 blows the blown dust and debris through the hollow partition 403 into the bottom of the support box 2. The saturated gas inside the support box 2 is filtered through the filter plate 404 and sucked out by the suction fan 405, thereby collecting impurities.

[0027] The tensioning mechanism 5 comprises a first guide roller set 501 arranged on the inner side of the support frame 1. A sliding groove 502 is fixedly arranged on the middle part of the inner side of the support frame 1. A sliding rod 503 is fixedly connected inside the sliding groove 502. A sliding block 504 is slidingly connected to the outer surface of the sliding rod 503. The sliding block 504 is slidingly connected to the sliding groove 502. A connecting spring 505 is fixedly connected to the upper surface of the sliding block 504. The connecting spring 505 is located on the outer side of the sliding rod 503. The side of the connecting spring 505 away from the sliding block 504 is fixedly connected to the sliding groove 502. A tensioning roller 506 is connected to one side of the sliding block 504. A second guide roller set 507 is arranged on the side of the inner side of the support frame 1 away from the first guide roller set 501. The support mechanism 6 comprises a fixed frame 601 fixedly connected to the side of the support box body 2 away from the support frame 1. A first support roller set 602 is arranged on the inner side of the fixed frame 601. A second support roller set 603 is arranged on the side of the inner side of the fixed frame 601 away from the first support roller set 602. The hot pressing roller set 3 is located between the first support roller set 602 and the second support roller set 603. When the hot pressing mechanism is used for hot pressing operation of elastic melt-blown non-woven fabric processing, the multi-layer non-woven fabric structure passes through the middle part of the first guide roller set 501 after conveying, then passes through the bottom of the tensioning roller 506 to the middle part of the second guide roller set 507. When the non-woven fabric is too tight during conveying, the non-woven fabric applies a certain force to the tensioning roller 506. The tensioning roller 506 drives the sliding block 504 to slide on the sliding rod 503, so that the connecting spring 505 is compressed, avoiding the tearing of the non-woven fabric during conveying. When the non-woven fabric is too loose during conveying, the sliding block 504 is driven to slide downward on the sliding rod 503 under the elastic potential energy of the connecting spring 505, realizing automatic tensioning of the non-woven fabric. The non-woven fabric processed by impurity removal passes through the middle part of the first support roller set 602 during conveying, moves to the middle part of the hot pressing roller set 3, and is subjected to multi-point pressing under the rotation of the two hot pressing rollers. The pressed non-woven fabric is conveyed out by the second support roller set 603 for the next process.

[0028] Working principle: When the hot pressing mechanism is used for hot pressing operations of elastic meltblown non-woven fabric processing, the multi-layer non-woven fabric structure passes through the middle of the No. 1 guide roller group 501 in the rear layer after conveying, and then passes around the bottom of the tensioning roller 506 to the middle of the No. 2 guide roller group 507. When the non-woven fabric is too tight during conveying, the non-woven fabric applies a certain force to the tensioning roller 506, and the tensioning roller 506 drives the slider 504 to slide on the slide bar 503, so that the connecting spring 505 is compressed to avoid the non-woven fabric from being too tight and tearing during conveying. When the non-woven fabric is too loose during conveying, the elastic potential energy of the connecting spring 505 pushes the slider 504 to slide downward on the slide bar 503 to realize automatic tensioning of the non-woven fabric. The tightly processed non-woven fabric enters through the slot on the side of the support box 2, and the ion fan 401 works to remove static electricity from the processed non-woven fabric, and at the same time blows off the dust and debris on the surface of the non-woven fabric, and the suction fan 405 works to blow the blown dust and debris through the hollow partition 403 into the bottom of the support box 2. The saturated gas inside the support box 2 is filtered through the filter plate 404 and then sucked out by the suction fan 405, so as to collect impurities. The non-woven fabric that has been processed for impurity removal passes through the middle of the No. 1 support roller group 602 during the transportation process and moves to the middle of the hot pressing roller group 3. Under the rotation of the two groups of hot pressing rollers, the multi-layer non-woven fabric structure is multi-point pressed. The pressed non-woven fabric is conveyed out through the No. 2 support roller group 603 for processing in the next step.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
