[0002] At present, the glass fiber yarn group in the glass fiber finished yarn group packaging process adopts the packaging of the finished yarn group by the adhesive film, which is a conventional packaging requirement mode.

[0003] However, the current yarn group adhesive film packaging and bottom coating are completely based on the manual mode, wherein the bottom of the adhesive film coated yarn group must be leveled, and the folded corner film is pressed inward to ensure that the adhesive film bottom corner of the yarn group bottom is not exposed. However, due to the weight of a single yarn group reaching 22.0 kg, and the current aging of employees, the labor intensity of employees in winding the adhesive and turning the bottom to smooth the adhesive film is very large. It is not convenient to manually smooth the adhesive film for a long time, which further leads to low efficiency. SUMMARY

[0008] Furthermore, the first folding assembly also includes a first slide rail and a first slider. The first slide rail is disposed on the mounting platform along a first direction, and the first slider is slidably disposed on the first slide rail and connected to the first folding component, so that the first driving component drives the first folding component to move along the extension direction of the first slide rail.

[0009] Furthermore, the smoothing component includes: two transmission members movably disposed on the first folding member, the two transmission members being respectively connected to two moving members; and a third driving member connected to the two transmission members respectively, so that the third driving member drives the two transmission members to move, thereby causing the two moving members to move relative to each other.

[0010] Furthermore, each of the two transmission components has a movable groove at the end furthest from the moving component. The smoothing assembly also includes a second slide rail and a second sliding member. The second slide rail is mounted on the first folding component, and the second sliding member is connected to the output shaft of the third drive component and slidably mounted on the second slide rail. A fixed rod is mounted on the second sliding member, and the fixed rod passes through the two movable grooves respectively, so that when the second sliding member is driven to move by the third drive component, the two transmission components drive the two moving components to move relative to each other. The extension direction of the second slide rail is set at an angle to the extension direction of the movable groove.

[0011] Furthermore, the smoothing component includes a third slide rail and two third sliding members. The third slide rail is disposed on the first folding member along the second direction, and the two third sliding members are slidably disposed on the third slide rail and respectively connected to two moving members, so that the two moving members are movably disposed along the extension direction of the third slide rail.

[0012] Furthermore, the second folding assembly includes: a second folding member movably disposed; and a second driving member disposed on the first folding assembly, wherein the second folding member is connected to the output shaft of the second driving member so that the second driving member drives the second folding member to move in a second direction.

[0013] Furthermore, the clamping device includes: a mounting body; two clamping components movably disposed on the mounting body; and a fourth driving component, which is drivenly connected to one of the two clamping components, wherein the two clamping components are drivenly connected through a transmission assembly so that the fourth driving component drives the two clamping components to move relative to each other.

Each smoothing device includes a first folding assembly and a smoothing component disposed on the first folding assembly. At least a portion of the two first folding assemblies is movably disposed relative to each other along a first direction. Each smoothing component includes two moving parts, which are movably disposed relative to each other along a second direction. After the at least a portion of the two first folding assemblies moves relative to each other along the first direction, the adhesive film exposed at the bottom of the yarn bundle is folded inward. Then, the two smoothing components contact the bottom of the yarn bundle respectively, and the two moving parts move away from each other along the second direction to smooth the adhesive film on the inner side of the bottom of the yarn bundle outward. The conveying device is disposed between the two smoothing devices for conveying the smoothed yarn bundle. In this way, by controlling at least a portion of the two first folding components to move relative to each other along the first direction, the adhesive film exposed at the bottom of the yarn bundle is folded inward. Since the outer wall of the yarn bundle is arc-shaped, the adhesive film has a large curvature after being folded by the two first folding components, and the folded adhesive film is in a wrinkled state. Then, by the two moving parts of the two smoothing components moving relative to each other along the second direction, the adhesive film located on the inner side of the fold after being folded by the first folding components is smoothed outward, realizing the automatic smoothing of the bottom of the adhesive film yarn bundle. This solves the problem of low efficiency in smoothing the adhesive film exposed at the bottom of the yarn bundle after packaging by hand in the prior art, effectively controls the product quality at the bottom of the adhesive film, reduces the labor intensity of employees, and improves the factory's packaging production efficiency.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To address the problem of low efficiency in manually smoothing the exposed adhesive film at the bottom of yarn bundles after packaging with adhesive film in existing technologies, this invention provides a packaging smoothing structure.

[0033] like Figures 1 to 9As shown, applying the technical solution of the present invention, the packaging smoothing structure includes a clamping device 10, a smoothing device 20, and a conveying device 30. The clamping device 10 is used to clamp the yarn bundle 1 after it has been packaged with adhesive film. Two smoothing devices 20 are arranged opposite to each other below the clamping device 10. Each smoothing device 20 includes a first folding assembly 21 and a smoothing assembly 22 disposed on the first folding assembly 21. At least a portion of the two first folding assemblies 21 is movably disposed relative to each other along a first direction. The smoothing assembly 22 includes two moving parts 220, which are movably disposed relative to each other along a second direction. After the at least a portion of the two first folding assemblies 21 moves relative to each other along the first direction, the adhesive film exposed at the bottom of the yarn bundle 1 is folded inward. Then, the two smoothing assemblies 22 respectively contact the bottom of the yarn bundle 1 and move away from each other along the second direction to smooth the adhesive film on the inner side of the bottom of the yarn bundle 1 outward. The conveying device 30 is disposed between the two smoothing devices 20 for conveying the smoothed yarn bundle 1.

[0034] By applying the technical solution of this embodiment, at least a portion of the two first folding components 21 are controlled to move relative to each other along a first direction, causing the adhesive film exposed at the bottom of the yarn bundle 1 to fold inward. Since the outer peripheral wall of the yarn bundle 1 is arc-shaped, the adhesive film has a large curvature after being folded by the two first folding components 21, and the folded adhesive film is in a wrinkled state. Then, by the two moving parts 220 of the two smoothing components 22 moving relative to each other along a second direction, the adhesive film located on the inner side after being folded by the first folding components 21 is smoothed outward, realizing the automatic smoothing of the bottom of the adhesive film yarn bundle 1. This solves the problem of low efficiency in smoothing the adhesive film exposed at the bottom of the yarn bundle 1 after packaging by hand in the prior art, effectively controls the product quality at the bottom of the adhesive film, reduces the labor intensity of employees, and improves the factory packaging production efficiency.

[0035] In this embodiment, the first direction and the second direction are set perpendicular to each other.

[0036] like Figure 1 , Figure 3 and Figure 9As shown, the smoothing device 20 also includes a second folding assembly 23. At least a portion of the second folding assemblies 23 on the two smoothing devices 20 are arranged to move relative to each other along a second direction, so that the adhesive film on the outer side of the bottom of the yarn ball 1 after being smoothed by the smoothing assembly 22 is folded inward. In this way, after the two first folding assemblies 21 fold the adhesive film exposed at the bottom of the yarn ball 1 inward and the two smoothing assemblies 22 smooth the adhesive film on the inner side of the bottom of the yarn ball 1, the excess adhesive film will be concentrated on both sides of the bottom of the yarn ball 1. At this time, the second folding assemblies 23 on the two smoothing devices 20 are symmetrically arranged along the second direction. Then, by the relative movement of at least a portion of the two second folding assemblies 23 along the second direction, the portion of adhesive film concentrated on both sides of the bottom of the yarn ball 1 is folded, and the adhesive film packaging action at the bottom of the yarn ball 1 is finally completed.

[0037] like Figure 2 , Figure 6 and Figure 7 As shown, the smoothing device 20 also includes a frame 24, on which an installation platform 25 is provided. The first folding assembly 21 includes a first folding component 210 and a first driving component 211. The first folding component 210 is movably disposed on the installation platform 25. The first driving component 211 is disposed on the installation platform 25 and is drivenly connected to the first folding component 210 to drive the first folding component 210 to move along a first direction. Thus, the first folding component 210 is connected to the telescopic rod head of the first driving component 211. The first folding component 210 is plate-shaped, and the side length of the first folding component 210 is greater than the diameter of the yarn bundle 1. The first driving component 211 drives the first folding component 210 to retract and extend in the first direction, so that the adhesive film exposed at the bottom of the yarn bundle 1 is folded inward. The first driving component 211 is provided with a first limit sensor to control the travel distance of the first driving component 211. Preferably, the first limit sensor controls the extension and retraction travel of the first driving component 211 to 18cm to avoid abnormal extension and retraction of the first driving component 211, which could lead to operational malfunctions.

[0038] In this embodiment, the first driving component 211 is a driving cylinder.

[0039] Specifically (not shown in the accompanying drawings), the first folding assembly 21 further includes a first slide rail and a first slider. The first slide rail is disposed on the mounting platform 25 along a first direction, and the first slider is slidably disposed on the first slide rail and connected to the first folding component 210, so that the first driving component 211 drives the first folding component 210 to move along the extension direction of the first slide rail. Thus, when the first driving component 211 drives the first folding component 210 to move along the first direction, the first slide rail and the first slider support the first folding component 210 and enable the first folding component to move back and forth along the first direction.

[0040] like Figure 2 and Figure 8 As shown, the smoothing component 22 includes two transmission members 221 and a third driving component 222. The two transmission members 221 are movably disposed on the first folding component 210, and are respectively connected to the two moving components 220. The third driving component 222 is connected to the two transmission members 221, so that the third driving component 222 drives the two transmission members 221 to move, thereby causing the two moving components 220 to move relative to each other. In the above configuration, the two transmission members 221 are linkage hinge mechanisms. Thus, by driving the two transmission members 221 to move relative to each other through the third driving component 222, the two transmission members 221 respectively drive the two moving components 220 to move relative to each other along the second direction, so that the wrinkled adhesive film at the bottom of the yarn bundle 1 on the inner side is smoothed outward.

[0041] In this embodiment, the third driving component 222 is a driving cylinder.

[0042] Specifically, each of the two transmission components 221 has a movable groove 2210 at the end away from the moving component 220. The smoothing component 22 also includes a second slide rail 223 and a second sliding member 224. The second slide rail 223 is disposed on the first folding component 210. The second sliding member 224 is connected to the output shaft of the third drive component 222 and is slidably disposed on the second slide rail 223. A fixing rod 2240 is disposed on the second sliding member 224. The fixing rod 2240 passes through the two movable grooves 2210 respectively, so that when the second sliding member 224 is driven to move by the third drive component 222, the two transmission components 221 drive the two moving components 220 to move relative to each other. The extension direction of the second slide rail 223 is set at an angle to the extension direction of the movable groove 2210. In the above configuration, the transmission component 221 is an L-shaped rod structure. The first folding component 210 is provided with two support columns. The bend of the transmission component 221 is rotatably connected to the support columns. One end of the transmission component 221 is connected to the moving component 220, and the other end is provided with a movable groove 2210 along its extension direction. The second slide rail 223 is provided on the first folding component 210 along the first direction. Then, when the third driving component 222 drives the second sliding component 224 to move along the second slide rail 223 along its extension direction, the fixed rod 2240 moves from one end to the other end in the two movable grooves 2210 respectively, so that the two transmission components 221 move in a "scissor" hinge mechanism along the second direction, thereby driving the two moving components 220 to open or close along the second direction.

[0043] Specifically, the smoothing component 22 includes a third slide rail 225 and two third sliding members. The third slide rail 225 is disposed on the first folding component 210 along the second direction. The two third sliding members are slidably disposed on the third slide rail 225 and respectively connected to the two moving components 220, so that the two moving components 220 are movably disposed along the extension direction of the third slide rail 225. Thus, when the third driving component 222 drives the two moving components 220 to move relative to each other along the second direction, the third slide rail 225 and the two third sliding members support the two moving components 220 and enable the two moving components 220 to open or close along the second direction.

[0044] like Figure 3 and Figure 9 As shown, the second folding assembly 23 includes a second folding component 230 and a second driving component 231; the second folding component 230 is movably disposed; the second driving component 231 is disposed on the first folding assembly 21, and the second folding component 230 is connected to the output shaft of the second driving component 231 so that the second driving component 231 drives the second folding component 230 to move along a second direction. In the above configuration, the second driving component 231 is connected to the first folding component 210 via an arc-shaped suspended plate, and the second folding component 230 is connected to the telescopic rod head of the second driving component 231. Thus, when the two first folding components 210 extend, the two second folding components 23 are symmetrically arranged along the second direction. The two second driving components 231 then drive the two second folding components 230 to move relative to each other along the second direction, causing the adhesive film on both sides of the bottom of the yarn bundle 1 to fold, ensuring the flatness of the adhesive film at the bottom of the yarn bundle 1 and preventing the adhesive film from being exposed at the bottom corners. The second driving component 231 is equipped with a second limit sensor to control the travel distance of the second driving component 231. Preferably, the second limit sensor controls the extension and retraction travel of the second driving component 231 to 12cm to avoid abnormal extension and retraction of the second driving component 231, which could lead to operational malfunctions.

[0045] In this embodiment, the second drive component 231 is a drive cylinder; a flat cylinder is preferred, which can provide greater torque and a smaller footprint.

[0046] like Figure 4As shown, the clamping device 10 includes a mounting body 11, two clamping components 12, and a fourth driving component 13. The two clamping components 12 are movably mounted on the mounting body 11. The fourth driving component 13 is drivenly connected to one of the two clamping components 12, and the two clamping components 12 are connected via a transmission assembly 14, so that the fourth driving component 13 drives the two clamping components 12 to move relative to each other. In this configuration, one clamping component 12 is connected to the telescopic rod head of the fourth driving component 13. Thus, the fourth driving component 13 drives one clamping component 12 to move, and the transmission assembly 14 drives the other clamping component 12 to move relative to each other, thereby clamping the yarn bundle 1 after it has been packaged with adhesive film.

[0047] In this embodiment, the fourth driving component 13 is a driving cylinder; both clamping components 12 are made of stainless steel and are a pair of vise-shaped fingers. The inner side of the clamping component 12 is provided with a sponge block, which can avoid the quality hazards of scratching and rubbing during the process of grasping the yarn ball 1.

[0048] Specifically, the transmission assembly 14 includes a gear 140 and two racks 141, the two racks 141 being arranged opposite each other and meshing with the gear 140, the gear 140 being disposed between the two clamping members 12; two slide rods and two fourth sliding members, the two fourth sliding members being slidably sleeved on the two slide rods respectively, the fourth sliding members being connected to the clamping members 12 and the racks 141 respectively, so that the fourth driving member 13 drives the racks 141 to move along the extension direction of the slide rods to drive the two clamping members 12 to move relative to each other. In this way, the fourth driving component 13 drives one clamping component 12 to move along the extension direction of the slide rod and drives one rack 141 to move. Through the transmission of the gear 140, the other rack 141 moves relative to it, thereby driving the other clamping component 12 to move relative to it along the extension direction of the slide rod at the same time, so as to perform clamping or opening movements on the yarn ball 1. In the above configuration, the fourth sliding component is a linear bearing, which has the characteristics of precise movement, simple installation, good dustproof sealing and high working accuracy, so as to ensure the normal extension and retraction of the clamping device 10.

[0049] In this embodiment (not shown in the accompanying drawings), the conveying device 30 is disposed between and below the two smoothing devices 20. The conveying device 30 includes a transport component 31 and a fifth drive component 32 connected thereto. The transport component 31 is a belt conveyor, and the fifth drive component 32 is a drive motor to provide sufficient torque to drive the belt conveyor to transport the yarn ball 1, which has been folded, smoothed and packaged by the smoothing device 20, to the next process.

[0050] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0051] The packaging smoothing structure includes a clamping device, a smoothing device, and a conveying device. The clamping device is used to clamp the yarn bundle after it has been packaged with adhesive film. Two smoothing devices are arranged opposite each other below the clamping device. Each smoothing device includes a first folding assembly and a smoothing component disposed on the first folding assembly. At least a portion of the two first folding assemblies is movably disposed relative to each other along a first direction. Each smoothing component includes two moving parts that are movably disposed relative to each other along a second direction. After the at least a portion of the two first folding assemblies moves relative to each other along the first direction, the adhesive film exposed at the bottom of the yarn bundle is folded inward. Then, the two smoothing components contact the bottom of the yarn bundle respectively, and the two moving parts move away from each other along the second direction to smooth the adhesive film on the inner side of the bottom of the yarn bundle outward. The conveying device is disposed between the two smoothing devices for conveying the smoothed yarn bundle. In this way, by controlling at least a portion of the two first folding components to move relative to each other along the first direction, the adhesive film exposed at the bottom of the yarn bundle is folded inward. Since the outer wall of the yarn bundle is arc-shaped, the adhesive film has a large curvature after being folded by the two first folding components, and the folded adhesive film is in a wrinkled state. Then, by the two moving parts of the two smoothing components moving relative to each other along the second direction, the adhesive film located on the inner side of the fold after being folded by the first folding components is smoothed outward, realizing the automatic smoothing of the bottom of the adhesive film yarn bundle. This solves the problem of low efficiency in smoothing the adhesive film exposed at the bottom of the yarn bundle after packaging by hand in the prior art, effectively controls the product quality at the bottom of the adhesive film, reduces the labor intensity of employees, and improves the factory's packaging production efficiency.
