Description

Technical Field

[0001] The invention relates to the technical field of non-woven fabric production and processing, in particular to an automatic packaging device for non-woven fabric rolls. Background Art

[0002] Nonwoven fabric, also known as nonwoven fabric or non-woven fabric, is a sheet, web or mat made of directional or randomly arranged fibers through friction, adhesion, bonding or a combination of these methods. It has the characteristics of high strength, good durability, strong filtration and large-scale production. Therefore, it is widely used in medical, health, agriculture, packaging, clothing and construction industries.

[0003] After production, non-woven fabrics are usually wound onto reels to form non-woven fabric rolls for easy transportation and use. After the non-woven fabric rolls are formed, they need to be packaged to protect the internal products, prevent moisture and dust, facilitate handling and identify information.

[0004] At present, when non-woven fabric rolls are packaged, a film is usually wrapped around the outside of the non-woven fabric roll for packaging. Among them, the Chinese invention patent with publication number CN112093524A discloses an automatic packaging system and method for non-woven fabrics, in which glue is sprayed on both sides of the non-woven fabric through a provided gluing component, and then a waterproof film is applied to both sides of the non-woven fabric through a film roller. The coated non-woven fabric is rolled up by a winding roller, and the distance between the two film rollers is kept unchanged by an elastic component. The winding roller is made compact when rolling by a pressing component, which is convenient for storage and transportation.

[0005] The Chinese utility model patent with publication number CN218519899U discloses a fully automatic self-positioning cloth roll baling machine, which pushes the clamping turntable to clamp or detach the two sides of the cloth roll by moving the swing arm seat closer or farther on the frame, and the baling mechanism installed on the frame wraps the film around the outer surface of the cloth roll, so as to realize baling at any position within the travel range, replacing manual wrapping of the film around the outer surface of the cloth roll.

[0006] Although the technical solutions disclosed in the above two patents have improved the packaging efficiency and packaging effect compared with the manual film wrapping method, the following problems still exist: 1. During the film winding process, part of the film will curl or overlap, which is prone to bulging, and the area of ​​the film wrapped on the non-woven fabric roll will become smaller. More film is needed to complete the packaging, which affects the packaging quality and increases the amount of film used.

[0007] 2. After the film moves to both ends of the non-woven fabric roll, the part that exceeds the end surface is used to protect the two end surfaces of the non-woven fabric roll. However, in the existing packaging process, the film that exceeds the two ends of the non-woven fabric roll is not compacted and tightened, resulting in the problem that this part of the film is not close to the non-woven fabric roll and cannot play an effective protective effect, affecting the packaging quality.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0035] like Figure 1 and Figure 2 As shown, an automatic packaging device for non-woven fabric rolls comprises: a base 1, an upper end surface of the base 1 is provided with a U-shaped seat 2 with an opening upward, which is rotatable by a driving shaft, the driving shaft is connected to an external motor 1 (not shown in the figure), two vertical sections of the U-shaped seat 2 are rotatable along the length direction of the U-shaped seat 2 and are provided with a plurality of groups of equally spaced conveying rollers 3, a lifting seat 4 is provided between the two vertical sections of the U-shaped seat 2 so as to slide up and down together, the lifting seat 4 is driven by an external hydraulic cylinder 1 (not shown in the figure) to move up and down, an L-shaped frame 5 is fixedly provided on the left side of the base 1, and a limiting unit 6 is provided between the frame 5 and the lifting seat 4.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, the frame 5 is provided with a packaging mechanism 7 for winding the film onto the non-woven fabric roll, and the packaging mechanism 7 includes a sliding frame 70. The vertical section of the frame 5 slides up and down and penetrates the sliding frame 70. A film roll for releasing the film (not shown in the figure) is provided on the left side of the sliding frame 70. A hanging frame 700 is fixedly provided on the right side of the sliding frame 70 through two L-shaped strip plates. A rotating roller 701 is rotatably provided in the hanging frame 700 through two rotating shafts distributed front and back and with axes extending from top to bottom. Two front-to-back symmetrical lifting blocks 702 are slidably provided on the vertical section of the frame 5. A moving plate 703 is commonly provided on the right sides of the two lifting blocks 702. Two rotating rollers 704 that are symmetrical front-to-back and with axes extending from left to right are provided on the moving plate 703.

[0037] like Figure 4 and Figure 5 As shown, the frame 5 is provided with a driving unit 71 for driving the sliding frame 70 to move back and forth up and down and the rotating roller 704 to rotate. The driving unit 71 includes a reciprocating screw 710, and the reciprocating screw 710 is connected to an external motor 2 (not shown in the figure). A reciprocating screw 710 with a vertical axis and passing through the lifting blocks 702 in a one-to-one correspondence is rotatably provided on the vertical section of the frame 5. The reciprocating screw 710 is threadedly matched with the corresponding lifting blocks 702.

[0038] It should be noted that existing conveying equipment such as conveyor belts are provided on both the front and rear sides of the U-shaped seat 2, which are used to convey the unpackaged non-woven fabric rolls to the conveying roller 3 and to send out the packaged non-woven fabric rolls. Before the packaging operation, the film roll is installed on the left side of the hanging frame 700, and the film is passed through the two rotating rollers 704 and the two turning rollers 701 in sequence. It should also be noted that the film is moved from bottom to top during the process of passing between the two rotating rollers 704 and the two turning rollers 701, so as to avoid the film placement being affected by the small spacing between the two rotating rollers 704 and the two turning rollers 701. After the non-woven fabric roll is moved to the specified position and fixed, the free end of the film is fixed on the upper right side of the U-shaped seat 2, and then wound and packaged.

[0039] During operation, after the non-woven fabric roll moves onto the conveying roller 3, the non-woven fabric roll is manually moved to the designated packaging position, and the external hydraulic cylinder 1 works to make the lifting seat 4 rise and lift the non-woven fabric roll, and the limiting unit 6 works to fix the non-woven fabric roll for subsequent winding and packaging. Then, the external motor 2 in the driving unit 71 works to drive the reciprocating screw rod 710 to rotate, so that the lifting block 702 moves back and forth up and down, and the lifting block 702 drives the rotating roller 701, the moving plate 703, the rotating roller 704 and the film to move back and forth up and down. During the movement, the external motor 1 works to drive the U-shaped seat 2 and the non-woven fabric roll to rotate synchronously through the driving shaft, so that the film is wound onto the non-woven fabric roll during the up and down reciprocating movement, completing the packaging operation, and finally the film is manually torn off and the non-woven fabric roll is removed, and then the above process is repeated to carry out the packaging operation of the next non-woven fabric roll.

[0040] In the above process, when the rotating roller 701 and the rotating roller 704 move back and forth up and down, the two rotating rollers 701 press against the film, and the driving unit 71 drives the two rotating rollers 704 to rotate during the up and down reciprocating movement. This ensures that the film is taut and does not fold or entangle with each other, so that the film can be evenly wound onto the non-woven fabric roll, avoiding the problem of insufficient winding of some parts of the non-woven fabric roll or no winding of some parts, thereby ensuring the overall packaging quality.

[0041] The conveying roller 3 on the U-shaped seat 2 facilitates the non-woven fabric roll to be moved to a designated position and quickly removed after packaging, thereby improving the efficiency and convenience of batch automatic packaging of the non-woven fabric rolls.

[0042] like Figure 1 and Figure 2 As shown, the limiting unit 6 includes a lifting plate 60. The upper end surface of the vertical section of the frame 5 is provided with a lifting plate 60 which slides up and down through a fixed column. The lifting plate 60 is driven by an external hydraulic cylinder 2 (not shown in the figure) to move up and down. A lower pressure plate 600 is fixedly sleeved on the lifting plate 60 through a central column with a vertical axis. A plurality of equidistantly distributed support plates 601 are fixedly provided on the lifting seat 4 through partition columns, and a limiting group 61 is provided on the central support plate 601.

[0043] like Figure 2 and Figure 3 As shown, the limiting group 61 includes a support plate 610, and two arc-shaped support plates 610 are slidably arranged on the central support plate 601 to the left and right, and the opposite surfaces of the two support plates 610 are hinged with hinge bars 611, and a square block 612 is hinged between the two hinge bars 611, and a spring rod 613 with a vertical axis is arranged between the square block 612 and the corresponding support plate 601, and a receiving tube 614 that cooperates with the center column is fixedly arranged on the upper end surface of the square block 612.

[0044] During operation, after the non-woven fabric roll is moved to the designated position on the U-shaped seat 2, the external hydraulic cylinder 1 works to make the lifting seat 4 drive the multiple support plates 601 thereon to rise, and the multiple support plates 601 pass through the area between the two corresponding adjacent conveying rollers 3, and the non-woven fabric roll is lifted by the cooperation of the multiple support plates 601, and at this time, the two opening plates 610 move up to the reel of the non-woven fabric roll, and then the external hydraulic cylinder 2 works to make the lifting plate 60 drive the central column and the lower pressure plate 600 thereon to move down synchronously, and the central column continues to move down and is inserted into the bearing The receiving tube 614 is inserted into and presses down the receiving tube 614, so that the receiving tube 614 continues to move downward, and the receiving tube 614 drives the square block 612 to move continuously, and makes the two hinge strips 611 open, and the two opening plates 610 move away from each other until they are close to the inner wall of the roll. In this process, the spring rod 613 is compressed, and at the same time, the center column drives the lower pressure plate 600 to press the non-woven fabric roll onto the support plate 601, completing the limiting fixation of the upper and lower ends of the non-woven fabric roll. The above operation completes the clamping and fixation of the non-woven fabric roll, which is convenient for the subsequent winding and packaging process.

[0045] During the above clamping process, the center column is inserted into the receiving tube 614 so that the lower pressure plate 600, the center column, the receiving tube 614, the support plate 601, the lifting plate 60 and the frame 5 together form a rectangular frame, which improves the stability of the subsequent non-woven fabric roll rotation packaging process and ensures the quality of film winding and packaging.

[0046] After completing the packaging operation, the external hydraulic cylinder 1 and the external hydraulic cylinder 2 are reset, so that the support plate 601 moves down to the bottom of the conveying roller 3 and the center column moves out of the reel. The elastic force generated by the deformation of the spring rod 1 613 causes the hinged strip 611 to drive the support plate 610 to reset, so that the non-woven fabric roll wrapped with the film can be taken down.

[0047] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the packaging mechanism 7 also includes a connecting frame 72, the right end face of the lifting block 702 is fixedly provided with the connecting frame 72, the moving plate 703 is fixedly provided between the two connecting frames 72, and the lower end face of the moving plate 703 is fixedly provided with four vertical plates 720 arranged in a matrix, and a rotating shaft 721 with an axis extending from left to right is jointly rotated between the two vertical plates 720 opposite to each other on the left and right, and the rotating roller 704 is fixedly sleeved on the corresponding rotating shaft 721, and the driving unit 71 also includes a gear 1 722, and the left side of the rotating shaft 721 is fixedly sleeved with a gear 1 722, and the right end face of the vertical section of the frame 5 is fixedly provided with two front-to-rear symmetrical rack plates 1 723 through a fixing bar, and the two gears 1 722 are both located between the two rack plates 1 723, and the rack plates 1 723 are both meshed with adjacent gears 1 722.

[0048] like Figure 4 and Figure 5 As shown, the driving unit 71 also includes a vertical column 711, and the lower end surface of the connecting frame 72 is fixedly provided with a vertical column 711 with a vertical axis, and two vertically distributed push plates 712 are fixedly provided on the two vertical columns 711. The two push plates 712 are respectively located on the upper and lower sides of the sliding frame 70 and the push plates 712 are used to push the sliding frame 70. The frame 5 is provided with an auxiliary group 73 for cooperating in pushing the sliding frame 70 to move reciprocally up and down.

[0049] like Figure 5 and Figure 7 As shown, the auxiliary group 73 includes a locking groove 730, and the left end face of the vertical section of the frame 5 is provided with a plurality of locking grooves 730 equidistantly distributed from top to bottom, and the locking groove 730 is an isosceles trapezoidal shape with the small diameter section facing right, and the front end face of the sliding frame 70 is fixedly provided with a plurality of fixed blocks 731 equidistantly arranged from top to bottom, and a clamping column 732 with an axis extending from left to right is slidably penetrated on the fixed block 731, and a locking block 733 cooperating with the locking groove 730 is fixedly provided on the right end face of the clamping column 732, and a spring 734 mounted on the clamping column 732 is fixedly provided between the locking block 733 and the corresponding fixed block 731.

[0050] After the non-woven fabric roll is placed and locked, one end of the film that has passed through the two rotating rollers 704 and the two turning rollers 701 in sequence is manually fixed on the right vertical section of the U-shaped seat 2 (it should be noted that the film can be fixed by wrapping or sticking one end of the film on the right vertical section of the U-shaped seat 2). Then, the external motor 1 works to drive the U-shaped seat 2 and the non-woven fabric roll to rotate synchronously through the drive shaft, and the external motor 2 works to make the two reciprocating screws 710 rotate synchronously, and the cooperation between the reciprocating screw 710 and the corresponding lifting block 702 makes the lifting block 702 move back and forth up and down.

[0051] During the movement of the lifting block 702 from bottom to top, the lifting block 702 drives the vertical column 711 and the two pushing plates 712 to move upward synchronously, and the lower pushing plate 712 drives the sliding frame 70 and the film to move synchronously. At this time, the two rotating rollers 704 are located in the upper area of ​​the film, and the hanging frame 700 and the rotating roller 701 move synchronously to ensure that the film remains taut and not entangled during the process of being wound onto the non-woven fabric roll. Secondly, in the above process, the lifting block 702 drives the connecting frame 72, the moving plate 703, the vertical plate 720 and the rotating roller 704 to move upward synchronously, and the gear 1 The engagement between 722 and the corresponding rack plate 723 enables the rotating shaft 721 to drive the rotating roller 704 to rotate synchronously. The two rotating rollers 704 rotate in opposite directions. The friction between the two rotating rollers 704 and the film causes the upper end portion of the film to tend to move upward. Therefore, in the process of the film moving upward, the film is tightened by the rotation of the rotating rollers 704, which facilitates the film to be wound onto the non-woven fabric roll. As the lifting block 702 moves from bottom to top, the film is wound on the non-woven fabric roll from bottom to top. When it moves to the highest point, the lifting block 702 starts to move downward.

[0052] When the lifting block 702 moves from top to bottom, the lifting block 702 first drives the connecting frame 72, the movable plate 703 and the pushing plate 712 to move downward synchronously. At this time, the locking block 733 is locked in the corresponding locking groove 730 by the elastic force of the spring 1 734. Therefore, the sliding frame 70 is in a fixed state during this process. As the connecting frame 72 continues to move downward, the two rotating rollers 704 move to the lower side of the film, and the upper pushing plate 712 contacts the upper end surface of the sliding frame 70. Then, as the lifting block 702 continues to move downward, The lifting block 702 drives the upper push plate 712 to push the sliding frame 70 to move downward synchronously. In this process, the sliding frame 70 is intermittently supported by the cooperation between the locking block 733 and the locking groove 730. In the process of moving downward, the two rotating rollers 704 are rotated by the cooperation between the rack plate 1 723 and the gear 1 722, and the directions of rotation of the two rotating rollers 704 are opposite. The rotation of the two rotating rollers 704 makes the lower end part of the film tend to move downward, so that the film is tightened, which is convenient for the film to be wound onto the non-woven fabric roll.

[0053] In summary, during the reciprocating up and down movement of the lifting block 702, the film is kept tight by the rotation of the rotating roller 704, thereby preventing the upper or lower end of the film from being wound during the up and down movement, thereby affecting the effect of the film being wound on the non-woven fabric roll.

[0054] like Figure 1 , Figure 2 and Figure 4As shown, the packaging mechanism 7 also includes a film pressing unit 74 arranged on the frame 5, and the film pressing unit 74 includes a vertical frame 740. The rear end face of the horizontal section of the frame 5 is fixedly provided with the vertical frame 740, and the front end face of the vertical frame 740 is slidably provided with two rack plates 741 distributed left and right, and a Z-shaped plate 742 is fixedly provided on the right rack plate 741 through a connecting strip, and the left rack plate 741 is fixedly connected to the lifting plate 60, and the horizontal section on the lower side of the Z-shaped plate 742 and the opposite surface of the lifting plate 60 are fixedly provided with spring rods 743, and the opposite surfaces of the two spring rods 743 are fixedly provided with film pressing plates 744.

[0055] like Figure 1 , Figure 2 and Figure 4 As shown, the front and rear end surfaces of the film pressing plate 744 are fixedly provided with inclined strips 745. The two inclined strips 745 on the same film pressing plate 744 are symmetrical front to back, and the two inclined strips 745 installed opposite to each other on different film pressing plates 744 are symmetrical up and down. Taking the inclined strip 745 on the front side of the upper film pressing plate 744 as an example, the inclined strip 745 is inclined downward from front to back.

[0056] like Figure 1 and Figure 4 As shown, the film pressing unit 74 further includes a push bar 746 , and two push bars 746 distributed up and down are fixedly provided on the right end surface of the suspension frame 700 , and the push bars 746 cooperate with the adjacent film pressing plates 744 .

[0057] like Figure 1 and Figure 2 As shown, the film pressing unit 74 also includes a gear 2 747. The front end surface of the vertical frame 740 is provided with a gear 2 747 whose axis extends from front to rear through a circular shaft rotation. The two rack plates 2 741 are symmetrical about the axis of the gear 2 747 and the rack plates 2 741 and the gear 2 747 are meshed with each other.

[0058] During operation, in the process of pressing the non-woven fabric roll up and down, the lifting plate 60 moves downward, driving the spring rod 2 743 and the film pressing plate 744 thereon to move downward synchronously. Before the lower pressing plate 600 presses the upper end of the non-woven fabric roll, the film pressing plate 744 presses the non-woven fabric roll and the spring rod 2 743 is deformed. Then, the lower pressing plate 600 continues to move downward to press the non-woven fabric roll. Secondly, in the process of the lifting plate 60 moving downward, the lifting plate 60 drives the corresponding rack plate 2 741 to move synchronously. Through the meshing between the rack plate 741 and the gear 747, the other rack plate 741 drives the Z-shaped plate 742 to move upward synchronously, and the right horizontal section of the Z-shaped plate 742 moves to the upper side of the conveying roller 3. At the same time, the spring rod 743 on the Z-shaped plate 742 drives the corresponding film pressing plate 744 to press against the lower end surface of the non-woven fabric, and as the Z-shaped plate 742 continues to move, the spring rod 743 deforms, causing the film pressing plate 744 to press the lower end surface of the non-woven fabric roll.

[0059] Then, in the process of the lifting block 702 moving from top to bottom, the lower pushing bar 746 and the lower film pressing plate 744 cooperate to complete the film pressing operation around the outer side of the lower end surface of the non-woven roll.

[0060] The two inclined strips 745 provided on the film pressing plate 744 facilitate the film pressing plate 744 to press the film onto the non-woven fabric roll during the rotation of the non-woven fabric roll, thereby improving the packaging effect and preventing the film from exceeding the upper and lower end surfaces of the non-woven fabric roll without being pressed tightly, thereby affecting the protective effect of the non-woven fabric roll.
