Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production, specifically to a nonwoven fabric packaging equipment. Background Technology

[0002] Non-woven fabric rolls need to be wrapped with film before leaving the factory to isolate them from dust, moisture, and other contaminants during transportation, ensuring product cleanliness and integrity. Since the length of non-woven fabric rolls is produced according to customer requirements, this results in a wide variety of outer diameter specifications and significant weight. Existing packaging equipment has limited adjustment capabilities and lacks stable support and positioning mechanisms for large-diameter, heavy rolls. Therefore, there is no equipment capable of reliably packaging various types of non-woven fabric rolls. Typically, multiple people manually wrap the film, resulting in low efficiency and high costs. Therefore, it is necessary to address this problem. Utility Model Content

Detailed Implementation

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] As used herein, the terms “parallel,” “perpendicular,” and the like are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0027] like Figure 1 , 2 As shown in Figure 3, a nonwoven fabric packaging device includes a frame with: a material support mechanism for supporting the nonwoven fabric roll to be packaged; a clamping mechanism for abutting and clamping the ends of the circular cardboard and the nonwoven fabric roll together; a film release mechanism for releasing the packaging film; and an adjustment mechanism for adjusting the rotation of the nonwoven fabric roll so that the packaging film wraps around the nonwoven fabric roll and the circular cardboard at both ends. It also includes an unloading mechanism for unloading the wrapped nonwoven fabric roll.

[0028] The nonwoven fabric roll is adjusted to rotate via a set adjustment mechanism, allowing the packaging film released by the film-laying mechanism to wrap around the outer periphery of the nonwoven fabric roll, thus reliably wrapping it. The unloading mechanism facilitates the unloading of the packaged nonwoven fabric roll, reducing packaging stress.

[0029] Further, such as Figure 3 , 4 As shown, the material support mechanism includes parallel spaced support shafts A and B, with the nonwoven fabric roll arranged horizontally on them. An adjustment mechanism rotates support shafts A and / or B to drive the nonwoven fabric roll to rotate. Support shafts A and B are rotatably mounted on a support bracket, which is movably mounted on the material support frame. An unloading mechanism adjusts the posture of the support bracket to unload the nonwoven fabric roll. The support bracket includes two oppositely arranged mounting plates 15. Both ends of support shafts A and B are rotatably mounted on the support bracket. The two mounting plates 15 are connected by a connecting rod. Both ends of support shaft A extend to the outer sides of the two mounting plates 15, forming mounting shaft sections 13. The outer ends of the mounting shaft sections 13 are rotatably assembled to the unloading frame via bearing seats A.

[0030] Specifically, the adjustment mechanism includes a drive component mounted on the mounting shaft section 13 between the mounting plate 15 and the A bearing seat. The drive component is a gear or transmission wheel, which is connected to the drive motor 17 via a transmission assembly. The drive motor 17 is fixedly mounted on the material support bracket. The unloading mechanism includes unloading cylinders 14 spaced along the length of the A material support shaft 11. The cylinder body of the unloading cylinder 14 is hinged to the material support frame, and the piston rod of the unloading cylinder 14 is hinged to the material support bracket. The material support bracket with the above structure has low implementation cost. Simultaneously, by rotatably assembling and connecting the two ends of the A material support shaft 11 to the material support bracket and the material support frame respectively, the drive motor 17 and the unloading cylinders 14 can meet the requirements for driving the rotation of the nonwoven fabric roll and unloading. When wrapping the packaging film, the height of the A material support shaft 11 and the B material support shaft 12 are the same. The drive motor 17 drives the A material support shaft 11 to rotate, causing the nonwoven fabric roll to rotate and the B material support shaft 12 to rotate. After packaging, the unloading cylinder 14 adjusts the material support bracket to flip over, and the B material support shaft 12 is raised, thereby removing the non-woven fabric roll from the A material support shaft 11 and the B material support shaft 12. The material support frame is equipped with a support pad 16, which supports the movable end of the mounting plate 15. The support pad 16 can be made of hard rubber material.

[0031] like Figure 5 , 6As shown in Figure 7, the clamping mechanism includes two clamping units arranged opposite to each other. The two clamping units include clamping plates 31 arranged vertically. The clamping plates 31 are movably installed at the lower end of the boom 30 in the vertical direction. The boom 30 is provided with a lifting adjustment component for adjusting the clamping plates 31 to raise and lower. The upper end of the boom 30 is slidably installed on the crossbeam 22 along the length direction of the A material support shaft 11. The two ends of the crossbeam 22 are fixedly installed on the column 21. The crossbeam 22 is provided with an A2 adjustment component for adjusting the movement of the boom 30. A clamping plate 31 is rotatably mounted on one end of an A mounting rod 32. An A1 assembly 33 is located in the middle of the A mounting rod 32. The other end of the A mounting rod 32 is movably mounted within an A assembly 341, which is fixedly mounted on an A2 assembly 34. A drive spring 35 is located on the A mounting rod 32 between the A1 and A2 assemblies 34. The drive spring 35 drives the clamping plate 31 to move away from the A2 assembly 34. The A2 assembly 34 is composed of C-shaped plates. An identifier 36 is located on the A1 assembly 33, and a sensor 37 for detecting the identifier is located on the A2 assembly 34. The A2 assembly is fixedly mounted on an A mounting block 38 on an A boom 30. The A mounting block 38 and the boom 30 slide vertically together. When the sensor 37 detects that the identifier is in place, it indicates that the cardboard has been clamped. At this time, the control device adjusts the sliding assembly seat 23 to stop moving. A rubber clamping pad can be provided on the clamping plate surface of the clamping plate 31 to improve the clamping effect.

[0032] Specifically, the lifting and adjusting assembly includes a vertically arranged adjusting rod A 39, which is rotatably mounted on the boom 30. The adjusting rod A 39 has a threaded section, and a nut block 391 is mounted on the threaded section. The nut block 391 and the A2 assembly 34 are fixedly connected. An adjusting handle 392 is located at the upper end of the adjusting rod A 39. By rotating the adjusting rod A 39, the height of the clamping plate is adjusted to match the outer diameter of the nonwoven fabric roll, satisfying the requirements for rotation and clamping, and adapting to the packaging of nonwoven fabric rolls of different sizes. The upper end of the boom 30 is equipped with a U-shaped sliding mounting seat 23, which is fitted onto the crossbeam 22. Two sets of A2 adjustment components are mounted on the crossbeam 22, adjusting the positions of the two sliding mounting seats 23. Each A2 adjustment component includes a synchronous belt slide module 24 mounted on the crossbeam 22. The sliding mounting seat 23 is fixedly connected to a slider on the synchronous belt slide module 24, which is driven by an A2 drive motor 25 located at the end of the crossbeam 22. The aforementioned A2 adjustment components reliably adjust the movement of the two clamping plates 31 towards the end of the nonwoven fabric roll located in the middle, clamping the cardboard and facilitating the rotation of the cardboard and nonwoven fabric roll together.

[0033] like Figure 1 , 2As shown in Figure 8, the film feeding mechanism includes a film feeder 45, which is mounted on a film feeding mounting base. The film feeding mounting base is movably mounted along the length of the A-support shaft 11, and is connected to an A1 adjustment assembly for adjusting its movement. The film feeder 45 includes a housing, on which a material shaft for assembling the packaging film roll 60 is provided, as well as a guide roller assembly for guiding the packaging film. The packaging film, after being guided by the guide roller assembly, is drawn out from the housing to package the non-woven fabric roll. Other devices that can release plastic film and are available on the market can also be used, as long as they can reliably release the packaging film. The film feeding mounting base is slidably mounted on the film feeding machine frame, which is provided with support plates for supporting the non-woven fabric roll. The support plates consist of an A1 support plate 41 and an A2 support plate 42, which are spaced apart to form an elongated gap 43. The film feeder 45 is located on the upper side of the support plate, and the film feed mounting base is located on the lower side of the support plate. The film feeder 45 is fixedly mounted on the film feed mounting base by a vertically arranged support plate 44, which is located at the elongated gap 43. By mounting the film feeder 45 with the support plate 44, the elongated gap 43 can be made narrower, avoiding any impact on the rolling of the nonwoven fabric roll. The A1 adjustment assembly includes a drive chain mounted on the film feeder frame and an A1 drive motor 17 that drives the drive chain. The film feed mounting base is connected to the drive chain. This adjusts the movement of the film feeder 45 along the length direction of the A support shaft 11, winding and wrapping the nonwoven fabric roll along its length. The height of the support plate is adapted to the height of the A support shaft 11. The B support shaft 12 and the support plate are located on opposite sides of the A support shaft 11. The support plate can be horizontal or arranged at a slight angle, and its height gradually decreases along the B support axis 12 towards the A support axis 11. This facilitates the unloading of packaged non-woven fabric rolls.

[0034] like Figure 8As shown, a transition frame is also provided on the outside of the film feeding frame. The film feeding frame is located between the transition frame and the support frame. The transition frame is equipped with a fixedly installed A1 transition plate 51 and a movable A2 transition plate 52. The A1 transition plate 51 is located between the A2 support plate 42 and the A2 transition plate 52, and the A1 transition plate 51 is arranged at an angle. The angle of inclination of the A1 transition plate 51 is greater than the angle of inclination of the support plate, and the height of the side closer to the A2 transition plate 52 is lower. The edge of the A2 transition plate 52 near the A1 transition plate 51 is hinged to the transition frame, and a tilting adjustment cylinder is provided on the lower side of the A2 transition plate 52 for adjusting its tilting. Since the height of the A support shaft 11 and the B support shaft 12 needs to be set for easy operation by the operator, their height is greater than the height of the conveyor line 71 for centralized conveying of nonwoven fabric rolls. By setting up the transition frame, it is convenient for the nonwoven fabric rolls to be transferred to the conveyor line 71. Due to the large weight and volume of the nonwoven fabric roll, when the roll roll rolls over, the A2 transition plate 52 and A1 transition plate 51 are adjusted to form a V-shape, so that the nonwoven fabric roll temporarily stops on the A1 transition plate 51. Then, the A2 transition plate 52 is flipped, so that the A2 transition plate 52 and A1 transition plate 51 are arranged at an angle, allowing the nonwoven fabric roll to roll onto the side conveyor line 71 for transport. This segmented rolling avoids the problem of unreliable stopping due to large height differences and excessive rolling potential energy, improving production safety and reliability. An inclined baffle 72 can be set on the other side of the conveyor line 71, with the conveyor line 71 located between the baffle 72 and the A2 transition plate 52. The conveying direction of the conveyor line 71 is consistent with the length direction of the nonwoven fabric roll. The height of the baffle 72 gradually increases as it moves away from the conveyor line 71, so that the nonwoven fabric roll can reliably roll onto the conveyor line 71 for transport. The conveyor line can be a chain conveyor line, which can reliably transport heavy nonwoven fabric rolls.

[0035] This utility model also provides a packaging method for non-woven fabric rolls, including the following operations: Adjusting the clamping plate to the appropriate height according to the size of the non-woven fabric roll; conveying the non-woven fabric roll to be packaged onto the A-support shaft 11 and B-support shaft 12; selecting two circular cardboard sheets that match the outer diameter of the non-woven fabric roll; laying the cardboard sheets flat on the A-support shaft 11 and B-support shaft 12 on the outer sides of both ends of the non-woven fabric roll; laying 1-3 layers of pre-cut packaging film on the cardboard sheets, ensuring the packaging film completely covers the cardboard sheets and extends to the outer perimeter of the cardboard sheets; attaching the cardboard sheets and packaging film together to the end of the non-woven fabric roll, with the cardboard sheets located on the outer side of the packaging film; adjusting the clamping plate to clamp and attach the cardboard sheets to the end of the non-woven fabric roll; smoothing and attaching the packaging film located on the outer side of the cardboard sheets to the outer periphery of the non-woven fabric roll; after both sides of the cardboard sheets are clamped, placing the packaging film extended by the film feeder 45 onto the end of the non-woven fabric roll, so that half of the packaging film is attached. Half of the nonwoven fabric is manually attached to the outer surface of the cardboard. The A-support shaft 11 is adjusted to rotate, causing the nonwoven fabric roll and the cardboard to rotate together. The film feeder 45 feeds the film, and the packaging film is wrapped around the cardboard and the nonwoven fabric roll to securely wrap them together. The same treatment is performed on the cardboard at the other end of the nonwoven fabric roll. Then, a matching number of packaging film wraps around the middle of the nonwoven fabric. 1-2 rounds of sample fabric are wrapped around the outer surface of the nonwoven fabric, and the ends of the sample fabric are fixed with adhesive tape. The nonwoven fabric roll is then adjusted to rotate, and the film feeder 45 moves back and forth along the length of the nonwoven fabric roll to feed the film, so that the packaging film wraps around the edge of the cardboard and the outer perimeter of the nonwoven fabric roll. After the predetermined number of wraps is reached, the rotation of the nonwoven fabric roll and the film feeder 45 are stopped. The clamping plate and the nonwoven fabric roll are separated, and the feeding bracket is adjusted to flip and remove the packaged nonwoven fabric roll from the support mechanism. Before adjusting the flipping of the feeding bracket, first adjust the A2 transition plate 52 and A1 transition plate 51 to a V-shape arrangement, and move the film feeder 45 to a clearance position. Repeat this process to package each roll of nonwoven fabric. Cardboard is used for packaging the ends to avoid damage to the edges of the nonwoven fabric caused by direct wrapping. This packaging method has low equipment cost, can adapt to the packaging needs of nonwoven fabrics of different sizes, improves its adaptability, and solves the problem of nonwoven fabrics being stained with discoloration during packaging.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
