Description

Technical Field

[0001] The invention relates to the technical field of mask production, and in particular to an unwinding device with a deviation correction and buffering function. Background Art

[0002] The filter material of a good protective mask should meet the following three conditions: first, the filtration efficiency is high when the mask fits well with the user's face; second, the breathing resistance is small; and third, the user feels comfortable. There are many materials for dust mask filter materials, including ordinary fabrics, animal hair, non-woven fabrics, etc. The most popular material in the national standard is an activated carbon felt material. The structure of the gauze mask has a poor fit with the human face. Many fine particles that are extremely harmful to us will enter the respiratory tract to the lungs through the gap between the mask and the face. Its filter material is generally some mechanical fabrics. The only way to achieve high dust blocking efficiency for this filter material is to increase the thickness. The negative effect of increasing the thickness is that the user feels a lot of breathing resistance and feels uncomfortable. The non-woven fabric that has been treated with electrostatics can not only block large dust particles, but also the static charge attached to its surface can adsorb fine dust through electrostatic attraction, achieving a very high dust blocking efficiency.

[0003] The core material used in the production of masks is meltblown cloth. The meltblown cloth needs to be processed during the production of masks. When the traditional meltblown cloth is unwound, its pay-off wheel is easy to move back and forth, thereby moving the meltblown cloth. When it moves to the spunlace electret machine, it is easy to change its position, resulting in the meltblown cloth being unable to carry out subsequent processing work normally. Therefore, a unwinding device with a correction and cache function is proposed to address the above problems. Summary of the invention

DETAILED DESCRIPTION

[0026] Embodiment 1:

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the present invention provides a technical solution:

[0028] A reeling device with a correction and buffering function comprises an unwinding machine 1 and a spunlace electret machine 2.

The correction device 7 comprises a fixed frame 701 and a rotating shaft 702. The upper end surface of the fixed frame 701 is slidably connected with a sliding rod 710. The lower end surface of the sliding rod 710 is fixedly connected with a limiting frame 712. The outer side of the limiting frame 712 is provided with a telescopic spring 711. Under the action of the telescopic spring 711, the limiting frame 712 is ensured to be meshed with the gear 708 at all times to achieve fixation. For the purpose of limiting, a gear 708 is provided under the limiting frame 712, and a rotating rod 709 is fixedly connected inside the gear 708. The outer side of the rotating rod 709 is fixedly connected to the extrusion frame 703. The lower end surface of the limiting frame 712 is arranged in an arc shape. This arrangement can cover the outer side of the gear 708 to achieve the purpose of limiting. The inner side of the lower end surface of the limiting frame 712 is fixedly connected with uniformly distributed teeth. The limiting frame 712 meshes with the gear 708 through the teeth. This arrangement can fix the gear 708, thereby preventing the rotating shaft 702 from rotating privately. An annular groove is provided on the outer side of the pay-off wheel 5, and the pay-off wheel 5 is slidably connected to the extrusion frame 703 through the annular groove. This arrangement allows the extrusion frame 703 to squeeze and limit the pay-off wheel 5 to achieve the purpose of deviation correction. The lower end surface of the fixed frame 701 is fixedly connected to the unwinding machine 1, and the fixed frame 701 is rotatably connected with a rotating shaft 702 inside. One end of the rotating shaft 702 is fixedly connected to the pay-off wheel 5, and the other end of the rotating shaft 702 is fixedly connected to a limiting wheel 707. An extrusion frame 703 is provided on the outer side of the rotating shaft 702. The lower end surface of the extrusion frame 703 is fixedly connected with a threaded sleeve 704.

One end of the threaded rod 705 is rotatably connected to the fixed frame 701, and the other end of the threaded rod 705 is fixedly connected with a handle 706. This arrangement can make the threaded rod 705 rotate to drive the threaded sleeve 704 to move, thereby achieving the purpose of limiting and correcting the pay-off wheel 5. The pay-off wheel 5 is rotatably connected inside the correcting device 7, and the cloth 6 is arranged on the outside of the pay-off wheel 5. The other side of the correcting device 7 is provided with a limiting device 8, and the limiting device 8 includes a limiting frame 801 and a sliding plate 802. The outside of the limiting frame 801 is fixedly connected to the unwinding machine 1, and the sliding plate 802 is slidably connected inside the limiting frame 801. The upper end surface of the sliding plate 802 is fixedly connected to the support rod 805, and the upper end surface of the support rod 805 is fixedly connected to the limiting plate 806. The lower end surface of the sliding plate 802 is fixedly connected to the support spring 804.The lower end surface of the support spring 804 is fixedly connected to the limit frame 801, the rear end surface of the sliding plate 802 is fixedly connected to the sliding shaft 803, the outer side of the sliding shaft 803 is slidably connected to the limit frame 801, the upper end surface of the limit plate 806 is fixedly connected to evenly distributed blocks, the outer side of the limit wheel 707 is fixedly connected to evenly distributed blocks, and the outer sides of the blocks are all arranged in an arc surface. This arrangement ensures that under the action of the blocks, the limit plate 806 and the limit wheel 707 can only rotate in one direction, and at the same time increases the friction force to facilitate the stable rotation of the rotating shaft 702, the lower end surface of the limit device 8 is fixedly connected to the unwinding machine 1, and the right side of the unwinding machine 1 is fixedly connected to a tensioning device 9 distributed front and back, the tensioning device 9 includes a tensioning frame 901 and a first rotating shaft 902, the outer side of the tensioning frame 901 is fixedly connected to the unwinding machine 1, and the inside of the tensioning frame 901 is fixedly connected to the first rotating shaft 902 and the first rotating shaft 902 distributed left and right. The second rotating shaft 908, the outer side of the first rotating shaft 902 is rotatably connected with a tensioning plate 903, the upper end surface of the tensioning plate 903 is slidably connected with a sliding block 904, the front and rear end surfaces of the sliding block 904 are fixedly connected with a guide shaft 905, the upper end surface of the sliding block 904 is fixedly connected with a tensioning spring 906, the right side of the tensioning device 9 is rotatably connected with a tensioning wheel 10, the upper end surface of the tensioning spring 906 is fixedly connected with a rotating frame 907, the interior of the rotating frame 907 is rotatably connected with the second rotating shaft 908, the other end of the tensioning plate 903 is rotatably connected with the tensioning wheel 10, this ensures that the tensioning wheel 10 can rotate, thereby protecting the stable feeding of the cloth 6, the outer side of the guide shaft 905 is slidably connected with the tensioning plate 903, the front and rear end surfaces of the tensioning plate 903 are slidably connected with the tensioning frame 901, this setting ensures that the tensioning plate 903 rotates stably, and ensures that the tensioning wheel 10 performs tensioning work on the cloth 6.

[0029] Working process: when in use, the power is turned on and the cloth 6 is on the pay-off wheel 5. At this time, the equipment is started, thereby driving the cloth 6 to move, and the cloth 6 thereby drives the pay-off wheel 5 to rotate. At this time, once the cloth 6 deviates, two people cooperate and pull the sliding rod 710 upwards at the same time to drive the limiting rod 712 below to separate from the gear 708, and then slowly adjust the handle 706 to drive the threaded rod 705 to rotate, so that its threaded sleeve 704 moves, and the threaded sleeve 704 moves the squeezing frame 703, so that the position of the pay-off wheel 5 can be adjusted. When it moves to the appropriate position, the squeezing frames 703 on both sides squeeze the pay-off wheel 5, thereby realizing the deviation correction work and ensuring the accurate and stable feeding of the cloth 6. During the feeding process, it is not easy to The pay-off wheel 5 can rotate easily, otherwise the cloth 6 may become loose. At this time, the sliding plate 802 is lifted up by the support spring 804, and then the support rod 805 is driven to move upward, so that the limit plate 806 contacts the limit wheel 707, so that it can only rotate in one direction, ensuring the stable movement of the pay-off wheel 5. When the cloth 6 moves, under the action of the tensioning wheel 10, it ensures stable movement. The second rotating shaft 908, the rotating frame 907 and the sliding block 904 ensure that the tensioning plate 903 moves downward, so that it is always in a tensioned state. The guide shaft 908 ensures that the sliding block 904 slides stably, ensuring that the cloth 6 accurately enters the water-jet electret machine 2, and then the subsequent work is carried out, which has good practical value.

[0030] Embodiment 2:

[0031] In Example 2, the parts that are the same as those in Example 1 are no longer repeated. The difference is that when the pay-off wheel 5 needs to be replaced, or the rotating shaft 702 needs to be reversed during maintenance, the sliding shaft 803 is moved downward. At this time, the sliding shaft 803 drives the sliding plate 802 to squeeze the support spring 804, thereby driving the support rod 805 to move downward, and the support rod 805 drives the limiting plate 806 to move downward, thereby separating from the limiting wheel 707. At this time, the limiting wheel 707 can drive the rotating shaft 702 to reverse, thereby facilitating replacement or maintenance work.
