Description

Technical Field

[0001] This utility model belongs to the field of meltblown fabric manufacturing technology, specifically relating to a meltblown fabric drying and storage device. Background Technology

[0002] When meltblown materials are used to produce water electret materials, they must undergo two processes: rinsing and drying. After rinsing, the material needs to be manually fed into the dryer. After drying, the next roll is put into the unwinding roller and the process is repeated.

[0003] In related technologies, the drying process of meltblown materials is not continuous. It requires that one roll of meltblown material be dried before the next roll is replaced. This intermittent production method requires a certain amount of time to change the meltblown material, which affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to propose a meltblown fabric drying and storage device to solve the problem that the intermittent production method in related technologies requires a certain amount of time to replace the meltblown material, which affects production efficiency.

[0005] Therefore, this utility model provides a meltblown fabric drying and storage device, comprising: a storage rack, a lifting frame disposed inside the storage rack, the lifting frame being used for lifting and lowering within the storage rack, a first guide roller disposed on the storage rack, and a second guide roller disposed on the lifting frame.

[0006] Preferably, the first guide roller and the second guide roller are arranged alternately.

[0007] Preferably, the first guide roller is rotatably connected to the fabric storage frame.

[0008] Preferably, the second guide roller is rotatably connected to the lifting frame.

[0009] Preferably, it also includes an unwinding device for feeding meltblown fabric to the fabric storage rack.

[0010] Preferably, the unwinding device includes a first unwinding roller and a second unwinding roller.

[0011] Preferably, the first unwinding roller is above the second unwinding roller.

[0012] Preferably, the unwinding device further includes a roll diameter detector for detecting the roll diameter of the first unwinding roller and the second unwinding roller.

[0013] Preferably, it also includes a drying device for drying the meltblown fabric output from the storage rack.

[0014] Preferably, the drying device includes a feed roller and a drying roller, wherein the feed roller is used to change the direction of the meltblown fabric so that the meltblown fabric fits into the drying roller.

[0015] Beneficial effects:

[0016] 1. This utility model provides a meltblown fabric drying and storage device. Through the cooperation of the storage rack and the lifting rack, when the meltblown fabric in the unwinding device is about to be unwound, the lifting rack is raised to reduce the distance between the first guide roller and the second guide roller, so that the meltblown fabric stored in the storage rack enters the drying device. At this time, the meltblown fabric roll in the unwinding device is replaced and connected end to end with the previous meltblown fabric. Then, the lifting rack is lowered to increase the distance between the first guide roller and the second guide roller, thereby increasing the meltblown fabric stored in the storage rack.

[0017] 2. In this utility model, the diameter of the meltblown fabric roll of the first unwinding roller and the second unwinding roller is detected by a roll diameter detector. When the unwinding is about to end, an alarm is triggered to replace the meltblown fabric roll in advance, which facilitates the bonding of the fabric. Attached Figure Description

[0021] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0022] Example 1:

[0023] Provided such as Figure 1A meltblown fabric drying and storage device is shown, comprising: a storage rack 1, a lifting frame 2 disposed within the storage rack 1, the lifting frame 2 being used for vertical movement within the storage rack 1, a first guide roller 11 disposed on the storage rack 1, and a second guide roller 21 disposed on the lifting frame 2. The first guide roller 11 is rotatably connected to the storage rack 1. The second guide roller 21 is rotatably connected to the lifting frame 2. The first guide roller 11 and the second guide roller 21 are arranged alternately. In one embodiment, the lifting frame 2 is servo-controlled, powered by a servo motor, and driven to move vertically via a linear module, ensuring that the tension of the meltblown fabric remains consistent during the lifting process. In another embodiment, the lifting frame 2 is raised or lowered by a cylinder or hydraulic cylinder. With the cooperation of the storage rack 1 and the lifting frame 2, when the meltblown fabric in the unwinding device is about to be unwound, the lifting frame 2 rises to reduce the gap between the first guide roller 11 and the second guide roller 21, so that the meltblown fabric stored in the storage rack 1 enters the drying device. At this time, the meltblown fabric roll in the unwinding device is replaced and connected end to end with the previous meltblown fabric. Then, the lifting frame 2 is lowered to increase the gap between the first guide roller 11 and the second guide roller 21, thereby increasing the amount of meltblown fabric stored in the storage rack 1.

[0024] It also includes an unwinding device 3, which is used to feed meltblown fabric to the fabric storage rack 1. The unwinding device 3 includes a first unwinding roller 31 and a second unwinding roller 32. The first unwinding roller 31 is above the second unwinding roller 32. The meltblown fabric roll is unwound by alternately feeding the first unwinding roller 31 and the second unwinding roller 32, which facilitates the replacement of the meltblown fabric roll.

[0025] The unwinding device 3 also includes a roll diameter detector 33, which is used to detect the roll diameter of the first unwinding roller 31 and the second unwinding roller 32. The roll diameter detector 33 detects the diameter of the meltblown fabric rolls of the first unwinding roller 31 and the second unwinding roller 32, and triggers an alarm when unwinding is nearing completion, allowing for early replacement of the meltblown fabric rolls to facilitate fabric bonding. In one embodiment, the roll diameter detector 33 is a distance sensor; the remaining roll diameter is determined by detecting the distance from the meltblown fabric roll to the distance sensor, and an alarm is triggered when the roll diameter falls below a set threshold.

[0026] It also includes a drying device 4, which is used to dry the meltblown fabric output from the fabric storage rack 1. The drying device 4 includes a feed roller 41 and a drying roller 42. The feed roller 41 is used to change the direction of the meltblown fabric so that the meltblown fabric is in contact with the drying roller 42.

[0027] The working principle is as follows: The first roll of meltblown fabric is placed into the first unwinding roller 31, and the meltblown fabric is drawn through the first guide roller 11 and the second guide roller 21. Then, it is fed onto the drying roller 42 by the feeding roller 41 for drying. At this time, the lifting frame 2 is in its lowest position, the distance between the first guide roller 11 and the second guide roller 21 is the largest, and the most meltblown fabric is stored. When the diameter of the meltblown fabric roll is lower than the set threshold, the system alarms and raises to change the roll. The lifting frame 2 rises to shorten the distance between the first guide roller 11 and the second guide roller 21, allowing the meltblown fabric in the storage rack 1 to enter the drying device 4. At the same time, the second roll of meltblown fabric is placed into the second unwinding roller 32, connecting the second roll of meltblown fabric end to end with the first roll of meltblown fabric, completing the roll change. Meanwhile, the lifting frame 2 gradually descends to ensure that there is a sufficient amount of meltblown fabric accumulated in the storage rack 1. This process is repeated to achieve uninterrupted drying operation and improve drying efficiency.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
