Description

Technical Field

[0001] This invention relates to an automated processing apparatus for nonwoven fabrics, and more particularly to a processing apparatus for making glove-like cleaning covers from nonwoven fabrics. This invention also relates to an automated processing method for nonwoven fabrics. Background Technology

[0002] The nonwoven fabric automated processing device applied for this time is mainly used for processing nonwoven fabric covers for cleaning. This mechanical product is a non-standard product made according to customer requirements. Therefore, there is currently no directly corresponding existing technology that can be referred to for description. For this reason, the applicant describes its own published patents as background technology.

[0003] The applicant previously filed an invention patent application with application number 202110548957.X on May 2, 2021. The patent text was published on October 19, 2021, and disclosed a bed cover machine, including a side forming mechanism, a deep folding mechanism, a corner sealing and cutting mechanism, and a cutting mechanism. The side forming mechanism includes a side folding component, an elastic band guiding component, a sealing component, and a first traction component. The deep folding mechanism includes a folding component, which includes a horizontally arranged second guide roller, a deep folding plate, and a lower support plate. The second guide roller is located below the deep folding plate. The deep folding plate is divided into a front folding plate and a rear folding plate. The rear folding plate is trapezoidal and inclined, while the front folding plate is square and horizontal. The lower support plate is located below the front folding plate, and there is a gap between the two. The corner sealing and cutting mechanism includes a corner sealing and cutting component and a second traction component. The material undergoes side forming, deep folding, and corner sealing in sequence, and is finally cut into disposable unit bed covers, realizing the automatic processing of bed covers.

[0004] Because of its large size, the bed cover machine requires multiple folds, and the seven folding mechanisms need to be vertically distributed, which takes up a lot of space and is not conducive to regular distribution, hindering the movement of workers. Moreover, the entire device involves a lot of parts, making it inconvenient to operate and costly. Summary of the Invention

[0008] Preferably, the third folding mechanism and the discharge mechanism are integrated into a folding discharge mechanism. The folding discharge mechanism includes an upper conveyor belt, a lower conveyor belt, and an end conveyor belt. The lower conveyor belt includes an upper conveying surface, a vertical conveying surface, and a lower conveying surface that are connected to each other. The upper conveying surface is laterally distributed. The end conveyor belt has an L-shaped conveying surface that matches the vertical conveying surface and the lower conveying surface, respectively. The upper conveying surface of the lower conveyor belt is opposite to the conveying surface of the upper conveyor belt and forms an upper transverse conveying gap. The vertical conveying surface and the vertical portion of the L-shaped conveying surface of the end conveyor belt form a vertical conveying gap. The upper conveyor belt is formed by tensioning three rollers. The end conveyor belt has a material platform above it that is flush with the upper transverse conveying gap. A vertically movable insert is arranged above the vertical conveying gap. The lower conveying surface and the transverse portion of the end conveyor belt are opposite to each other and form a lower transverse conveying gap.

[0014] This invention also provides an automated processing method for nonwoven fabrics, characterized by comprising the following steps:

[0015] 1. The feeding mechanism winds up the nonwoven fabric. The nonwoven fabric enters between the upper and lower rollers of the third pulling mechanism through the auxiliary roller and passes through to the rear. It passes through from the lower part of the pressure roller and then covers and wraps the triangular plate from top to bottom. It is folded and gathered from the rear tip of the triangular plate and enters between the two clamping rollers. After passing through, it goes around the outside of the vertical turning roller and then passes down through the lower auxiliary roller from the upper part of the oblique turning roller and enters between the upper and lower rollers of the first pulling mechanism and passes through to the rear. The fabric goes around the lifting adjustment roller and enters the welding mechanism from the top. The welding mechanism welds the three sides of the nonwoven fabric after the first fold and both sides of the exit.

[0016] Second, the welded non-woven fabric passes under the pressure roller on the rear side and covers the triangular plate of the second folding mechanism. Then, it is flipped over again by the second flipping mechanism and flattened. After the second fold, the non-woven fabric enters the cutting mechanism for cutting.

[0017] 3. The cut non-woven fabric cover enters the upper transverse conveying gap between the upper conveying surface of the lower conveyor belt and the upper conveyor belt. The non-woven fabric cover is driven forward by the lower and upper conveyor belts and is conveyed to the material platform. When the non-woven fabric cover is conveyed above the vertical conveying gap and the vertical conveying gap is aligned with the center line of the non-woven fabric cover, the insert plate moves downward to insert the non-woven fabric cover into the vertical conveying gap and completes the third fold of the non-woven fabric cover. The non-woven fabric cover then enters the lower transverse conveying gap laterally under the drive of the lower conveyor belt and the end conveyor belt, and is finally conveyed to the rear end.

[0018] Technical effects of the present invention:

[0019] 1) The processing device and method achieves fabric folding by configuring a folding mechanism with triangular plates, and adjusts the fabric after folding by configuring a turning mechanism with inclined turning rollers and vertical turning rollers. By configuring multiple sets of folding mechanisms and turning mechanisms, multiple folding can be achieved on a straight production line. Compared with the traditional structure that requires multiple vertical sections of the production line to achieve folding, the solution of this application is simpler and more efficient. The straight design is conducive to saving placement space and land use, and is also conducive to regular distribution and management.

[0020] 2) The overall structure of the device is simpler and more reasonable, using fewer parts to achieve higher processing efficiency, and is more convenient to operate and has lower cost. Attached Figure Description
