Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, and in particular to a strip threading device for aluminum foil. Background Technology

[0002] When aluminum foil strip is coated, it needs to be threaded between multiple coating rollers of the coating machine. When aluminum foil strip is used as a material for lithium-ion batteries, it needs to be threaded between multiple guide rollers of the slitting machine during the slitting process. When aluminum foil strip is wound up, it needs to be threaded between multiple guide rollers at the front end of the winding machine.

[0003] Aluminum foil strips need to be threaded between the rollers not only upon their initial entry but also after breakage. Current technology assists in threading the aluminum foil strip between the rollers by attaching multiple high-temperature adhesive tapes to various points on the strip's head. An operator then grasps the other ends of these tapes, dragging the strip through the rollers.

[0004] Although the above method can thread the aluminum foil strip between the rollers, it requires multiple high-temperature tapes to stick to multiple points at the head of the aluminum foil strip for dragging. This results in uneven distribution of dragging force on the aluminum foil strip, which can easily cause wrinkles and breakage. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model proposes a strip threading device for aluminum foil strips, which solves the problem that the existing threading method for assisting aluminum foil strips to be threaded into the roller system is prone to wrinkling and breakage.

[0006] This utility model provides a threading device for aluminum foil strip, which is set at the head end of the aluminum foil strip and assists in threading the aluminum foil strip into the roller system of various processing equipment. It includes a guide tube, a plurality of adhesive pieces that are fixed to the head end of the aluminum foil strip and spaced apart, and handle structures set at opposite ends of the guide tube. The guide tube extends along the width direction of the aluminum foil strip and its length is equal to the width of the aluminum foil strip. The plurality of adhesive pieces are arranged at intervals along the width direction of the aluminum foil strip.

[0007] Preferably, the guide fitting is a polyvinyl chloride pipe.

[0008] Preferably, the handle structure is a long strip-shaped perforation that penetrates the polyvinyl chloride tube on the side away from the aluminum foil strip, and the long strip-shaped perforation extends along the axial direction parallel to the polyvinyl chloride tube.

[0009] Preferably, the handle structure consists of multiple circular perforations penetrating the polyvinyl chloride tube on the side away from the aluminum foil strip, and the multiple circular perforations are arranged at intervals along the axial direction of the polyvinyl chloride tube.

[0010] Preferably, the adhesive is tape.

[0011] Preferably, the adhesive pieces are evenly spaced along the width direction of the aluminum foil strip.

[0012] Preferably, the guide tube is a silicone tube or a plastic tube.

[0013] Preferably, the adhesive is an adhesive that is bonded between the head end of the aluminum foil strip and the guide tube.

[0014] Preferably, there are at least three adhesive pieces, which are respectively disposed at opposite ends of the guide tube and at the middle position of the guide tube.

[0015] Compared with the prior art, the aluminum foil strip threading device of this utility model is designed by attaching a guide tube to the head end of the aluminum foil strip with adhesive, and setting a handle structure on the guide tube. The guide tube is limited to extend along the width direction of the aluminum foil strip and its length is equal to the width of the aluminum foil strip. Multiple adhesive pieces are arranged at intervals along the width direction of the aluminum foil strip. In this way, the head end of the aluminum foil strip can be flattened by the weight of the guide tube itself, and the drag force is relatively evenly distributed at all points of the head end of the aluminum foil strip. This makes it less likely to wrinkle and break during dragging, thereby avoiding waste caused by aluminum foil strip breakage and improving threading efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model embodiment provides a threading device for aluminum foil strips, combined with Figures 1 to 3As shown, it includes a guide tube 1, a plurality of adhesive pieces 2 that are attached and fixed to the head end of the aluminum foil strip 4 and spaced apart, and handle structures 3 disposed at opposite ends of the guide tube 1; the guide tube 1 extends along the width direction of the aluminum foil strip 4 and its length is equal to the width of the aluminum foil strip 4, and the plurality of adhesive pieces 2 are spaced apart along the width direction of the aluminum foil strip 4.

[0024] The aluminum foil strip threading device is located at the head end of the aluminum foil strip 4 and assists the aluminum foil strip 4 in threading into the roller system 5 of various processing equipment. The head end of the aluminum foil strip 4 is the end of the aluminum foil strip 4 that needs to be threaded into the roller system 5 of various equipment. The aluminum foil strip can be aluminum foil or aluminum strip. Figure 1 This is a simplified two-dimensional diagram; therefore, the dimensions of its components will differ from those of other diagrams. Figure 2 Or the dimensions of 3 are different; Figure 2 and Figure 3 The roller system 5 in the system includes a first roller 51, a second roller 52, a third roller 53, a fourth roller 54, and a fifth roller 55 arranged in sequence.

[0025] In this embodiment, the guide tube 1 is a polyvinyl chloride tube. By selecting a polyvinyl chloride tube, the soft characteristics of the polyvinyl chloride tube can be used to avoid damaging the aluminum foil strip 4 or scratching the roller system 5 during the tape threading process.

[0026] Of course, depending on the actual needs, the guide tube 1 can also be made of soft materials such as silicone tubes or plastic tubes, or a cylindrical or other shaped structure made of soft materials.

[0027] like Figure 1 As shown, the handle structure 3 is a long strip-shaped perforation that penetrates the PVC tube on the side away from the aluminum foil strip 4. The long strip-shaped perforation extends along the axial direction parallel to the PVC tube. This design makes it convenient for the operator's fingers to enter the long strip-shaped perforation to better grip the PVC tube and avoid the situation of slipping out of the hand when dragging.

[0028] Of course, depending on actual needs, the handle structure 3 can also be a plurality of circular perforations that pass through the polyvinyl chloride tube on the side away from the aluminum foil strip 4, with the plurality of circular perforations arranged at intervals along the axial direction of the polyvinyl chloride tube.

[0029] The adhesive component 2 is an adhesive tape, which is a high-temperature resistant tape to improve its adhesive effect; and the tape is short in length to avoid excessive tape affecting the surface quality of the aluminum foil strip 4.

[0030] The adhesive pieces 2 are evenly spaced along the width of the aluminum foil strip 4. This design can better distribute the drag force relatively evenly at the head end of the aluminum foil strip 4, avoiding the situation where wrinkles easily occur and breakage occurs during dragging.

[0031] Of course, depending on actual needs, the adhesive 2 can also be made of a high-temperature resistant adhesive that is used to adhere to the head end of the aluminum foil strip 4 and the guide tube 1.

[0032] like Figure 1 As shown, the adhesive component 2 includes at least three parts, which are respectively located at the opposite ends of the guide tube 1 and at the middle of the guide tube 1. This design can better distribute the drag force relatively evenly at the head end of the aluminum foil strip 4, avoiding the situation where it is prone to wrinkling and breakage during dragging.

[0033] To further improve the bonding and fixing effect between the guide tube 1 and the aluminum foil strip 4, glue can be applied directly to the contact area between the head end of the aluminum foil strip 4 and the guide tube 1, or tape can be used for bonding.

[0034] like Figure 1 As shown, to better grip the guide tube 1, the aluminum foil strip 4 near the guide tube 1 and located between two adjacent adhesive pieces 2 can be cut to leave two pre-drilled holes 41 for the operator's fingers to pass through. The positions of the two pre-drilled holes 41 correspond to the positions of the two handle structures 3. Of course, depending on actual needs, such as... Figure 2 As shown, only one reserved hole 41 can be set.

[0035] In this embodiment, the aluminum foil strip threading device uses a polyvinyl chloride (PVC) tube as the guide tube 1. The weight of the PVC tube itself also prevents the aluminum foil strip 4 from falling to its lowest point after being released. The direction of the PVC tube's weight is similar to the direction of the aluminum foil strip 4's weight. Figure 3 The direction of gravity is shown in the figure; at the same time, only one person is needed to feed the material and another person to thread the belt during the threading process. Compared with the existing threading method, taking a line length of about 100 meters and a roller system of about 130 rollers as an example, the average time can be shortened by 15 minutes per hour, which can save 75% of the threading time.

[0036] Compared with the prior art, the aluminum foil strip threading device of this utility model is designed by attaching a guide tube 1 to the head end of the aluminum foil strip 4 with an adhesive piece 2, and setting a handle structure 3 on the guide tube 1. The guide tube 1 is limited to extend along the width direction of the aluminum foil strip 4 and its length is equal to the width of the aluminum foil strip 4. Multiple adhesive pieces 2 are arranged at intervals along the width direction of the aluminum foil strip 4. In this way, the head end of the aluminum foil strip 4 can be flattened by the weight of the guide tube 1 itself, and the drag force is relatively evenly distributed at all parts of the head end of the aluminum foil strip 4. This makes it less likely to wrinkle and break during dragging, thereby avoiding waste caused by the breakage of the aluminum foil strip 4 and improving the threading efficiency.

[0037] It should be noted that the various embodiments described above with reference to the accompanying drawings are only illustrative of the present invention and not intended to limit its scope. Those skilled in the art should understand that any modifications or equivalent substitutions made to the present invention without departing from its spirit and scope should be covered within the scope of the present invention. Furthermore, unless the context otherwise requires, singular terms include plural forms, and vice versa. Additionally, unless specifically stated otherwise, all or part of any embodiment may be used in conjunction with all or part of any other embodiment.
