Description

Technical Field

[0001] This utility model relates to an unwinding device, and more particularly to an unwinding device for aluminum-plastic composite tapes used in the processing and production of aluminum-plastic composite tapes. Background Technology

[0002] Cables and optical cables are widely used as infrastructure. In the production process of optical cables, aluminum-plastic composite tape is used extensively as the metal armor layer of the optical cable, which plays a good role in shielding and moisture protection, and protects the cable core. In the production process of aluminum-plastic composite tape, an unwinding device is used.

[0003] Chinese Patent Publication No. CN220906693U discloses a fiberglass cloth unwinding device. This utility model can avoid the inertial rotation of the unwinding shaft due to the fiberglass cloth being stretched when the conveying device stops by using the friction between the brake block and the speed limiting disc, thereby avoiding the accumulation and wrinkling of the fiberglass cloth.

[0004] However, the above-mentioned patent will have the following problems in use: The unwinding shaft in the above-mentioned patent has a fixed diameter and length, but in the process of unwinding the aluminum-plastic composite tape through the unwinding device, since there are many specifications of aluminum-plastic composite tape, when the unwinding drum with aluminum-plastic composite tape wound on it is inserted into the unwinding shaft, the inner diameter of the unwinding drum is often larger than the diameter of the unwinding shaft, which makes it easy for the unwinding drum to shake during rotation. On the other hand, if the length of the unwinding shaft is too long, it will easily lead to uneven tension distribution and excessive inertia, which will make the aluminum-plastic composite tape easy to deviate during unwinding, thus leading to unstable unwinding. Utility Model Content

[0005] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that the unwinding shaft in the existing unwinding device is usually of fixed diameter and length. During the unwinding process of aluminum-plastic composite tape, the inner diameter of the unwinding cylinder is often larger than the diameter of the unwinding shaft. Moreover, if the length of the unwinding shaft is too long, it is easy to cause uneven tension distribution and excessive inertia. As a result, the aluminum-plastic composite tape is prone to shaking and deviation during the unwinding process, which leads to unstable unwinding.

[0006] To solve the above problems, this utility model provides an unwinding device for aluminum-plastic composite strip, including a base plate, an mounting plate fixedly connected to the upper end of the base plate, a motor fixedly connected to the left end of the mounting plate, the output end of the motor rotating through the mounting plate and fixedly connected to a mounting base, an unwinding roller provided on the right side of the mounting base, the unwinding roller including multiple short rollers located on the right side of the mounting plate, a double-headed screw provided in the inner cavity of the short roller, multiple grooves carved on the outer surface of the short roller, two sliders threaded on the outer surface of the double-headed screw, multiple limiting blocks fixedly connected to the outer surface of the sliders respectively corresponding to the multiple grooves, multiple adjusting plates corresponding to the multiple grooves respectively provided outside the short roller, a rotating rod rotatably connected between the adjusting plate and the limiting block, an insert rod fixedly connected to the right end of the double-headed screw, the right end of the insert rod... The movement passes through adjacent double-headed screws. Two magnetic rings are provided between two adjacent short rollers. The two magnetic rings are threaded onto the outer surface of the adjacent short rollers. One end of one magnetic ring is fixedly connected to multiple limiting rods. The limiting rods move through the other magnetic ring. The adjacent magnetic rings attract each other. The left end of the leftmost short roller is fixedly connected to the mounting base. The leftmost double-headed screw is rotatably connected to the mounting base. A positioning groove is chiseled at the right end of the base plate. A positioning block is provided in the positioning groove. A positioning plate is provided at the upper end of the base plate. The lower end of the positioning plate is fixedly connected to the positioning block. An adjusting rod is movably sleeved on the outer surface of the rightmost insertion rod. The right end of the adjusting rod moves through the positioning plate, and a ratchet is fixedly sleeved on the outer surface of the adjusting rod. A pawl is rotatably connected to the right end of the positioning plate.

[0007] In the above-mentioned unwinding device for aluminum-plastic composite tape, the unwinding roller is divided into multiple short rollers that can be spliced ​​together. The short rollers can be spliced ​​together according to the unwinding drum on which the aluminum-plastic composite tape is wound, thereby adjusting the length of the unwinding shaft. At the same time, the rotation of the double-headed screw can drive the slider to move, thereby changing the distance between the adjusting plate and the short rollers, so that the adjusting plate can abut against the inner wall of the unwinding drum, thereby effectively improving the stability of the unwinding device during use.

[0008] As a further improvement of this application, a ramp is fixedly connected to the right end of the positioning plate, and a compression spring is fixedly connected between the ramp and the pawl, and the pawl and the ratchet are engaged.

[0009] As a further improvement to this application, the threads at the left and right ends of the outer surface of the double-ended screw have opposite directions, and the longitudinal sections of both the insert rod and the limiting rod are regular hexagonal.

[0010] As a further improvement of this application, multiple chutes and multiple adjusting plates are arranged in a circular array around the central axis of the short roller, the adjusting plates are arc-shaped, and multiple adjusting plates can form a complete cylinder.

[0011] As another improvement of this application, the positioning groove is located directly below the unwinding roller, and both the positioning groove and the positioning block are inverted T-shaped.

[0012] As another improvement of this application, two support plates are fixedly connected to the upper end of the base plate, and auxiliary rollers are fixedly connected between the support plates and the mounting plate. The two auxiliary rollers are located on the front and rear sides of the unwinding roller, respectively.

[0013] As another improvement of this application, a rubber pad is fixedly connected to the end of the adjusting plate away from the rotating rod, and multiple rubber protrusions are fixedly connected to the end of the rubber pad away from the adjusting plate.

[0014] In summary, in practical applications, the limiting rod can be inserted into the adjacent magnetic ring, and the insertion rod can be inserted into the adjacent double-ended screw, thereby splicing the two short rollers and adjusting the length of the unwinding roller. When winding the aluminum-plastic composite strip, the double-ended screw can be rotated to move the two sliders simultaneously toward the center of the double-ended screw, thereby causing the rotating rod to rotate and adjusting the distance between the adjusting plate and the short roller. This allows the adjusting plate to fit against the inner wall of the unwinding drum, enabling the unwinding roller to be adjusted according to the actual specifications of the aluminum-plastic composite strip. This effectively avoids shaking or deviation of the unwinding device during use, thus effectively improving the stability of the unwinding device during operation. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figure 1 and Figure 2 The diagram shows an unwinding device for aluminum-plastic composite strip, comprising a base plate 1, an mounting plate 2 fixedly connected to the upper end of the base plate 1, and a motor 3 fixedly connected to the left end of the mounting plate 2. Those skilled in the art can select a suitable model of motor 3 according to actual needs, such as Y2-63M1-2-0.18KW. The motor 3 drives the rotation of the unwinding roller, thus facilitating the unwinding of the aluminum-plastic composite strip. The output end of the motor 3 rotates through the mounting plate 2 and is fixedly connected to a mounting base 4. An unwinding roller is located on the right side of the mounting base 4. Two support plates are also fixedly connected to the upper end of the base plate 1. An auxiliary roller 21 is fixedly connected between the support plates and the mounting plate 2. The two auxiliary rollers 21 are located on the front and rear sides of the unwinding roller, respectively. When the aluminum-plastic composite strip is unwound, it coils around the outer surface of one of the auxiliary rollers 21, thereby assisting in the unwinding of the aluminum-plastic composite strip and effectively improving the stability of the aluminum-plastic composite strip during unwinding.

[0027] Figure 2 , Figure 3 and Figure 4 The diagram shows that the unwinding roller includes multiple short rollers 5 located on the right side of the mounting plate 2. Each short roller 5 has a double-ended screw 6 inside its cavity. The left end of the leftmost short roller 5 is fixedly connected to the mounting base 4, and the leftmost double-ended screw 6 is rotatably connected to the mounting base 4. Multiple grooves 7 are chiseled on the outer surface of the short roller 5. Two sliders 8 are threaded onto the outer surface of the double-ended screw 6. Multiple limiting blocks 9, corresponding to the multiple grooves 7, are fixedly connected to the outer surface of the sliders 8. The outer surface of the limiting blocks 9 fits against the inner wall of the grooves 7. When the double-ended screw 6 rotates and drives the sliders 8 to move, it can limit the movement of the limiting blocks 9, effectively improving the stability of the limiting blocks 9 during movement. Multiple adjusting plates 10, corresponding to the multiple grooves 7, are provided outside the short roller 5. The adjusting plates 10 and the limiting plates 10... A rotating rod 11 is rotatably connected between blocks 9. A plug rod 12 is fixedly connected to the right end of the double-headed screw 6. The right end of the plug rod 12 movably passes through the adjacent double-headed screw 6. Two magnetic rings 13 are provided between two adjacent short rollers 5. The two magnetic rings 13 are respectively threaded onto the outer surface of the adjacent short rollers 5. Multiple limiting rods 14 are fixedly connected to the end of one of the magnetic rings 13. The limiting rods 14 movably pass through the other magnetic ring 13. The two adjacent magnetic rings 13 attract each other and insert the limiting rods 14 into the adjacent magnetic rings 13. At this time, the two magnetic rings 13 attract each other and stick together. The plug rod 12 is inserted into the adjacent double-headed screw 6, so that the two short rollers 5 stick together. Thus, the two short rollers 5 and the two double-headed screws 6 are installed and spliced, thereby adjusting the length of the unwinding roller.

[0028] Figure 4 and Figure 5 As shown: the threads at the left and right ends of the outer surface of the double-headed screw 6 turn in opposite directions. The longitudinal sections of the insert rod 12 and the limiting rod 14 are both regular hexagonal. The regular hexagonal insert rod 12 and the limiting rod 14 can restrict the double-headed screw 6 and the magnetic ring 13, so that it is not easy for the two short rollers 5 to wobble when they are spliced ​​together. When the two double-headed screws 6 are spliced ​​together, the rotation of one double-headed screw 6 can drive the rotation of the other double-headed screw 6. Multiple sliding grooves 7 and multiple adjusting plates 10 are arranged in a ring array around the central axis of the short roller 5. The adjusting plates 10 are arc-shaped, and multiple adjusting plates 10 can form a complete cylinder. The rotation of the double-headed screw 6 can make the two sliders 8 move towards each other or in opposite directions on the surface of the double-headed screw 6 at the same time, thereby causing the rotating rod 11 to rotate and adjust the distance between the adjusting plate 10 and the short roller 5, so that the adjusting plate 10 is in contact with the inner wall of the unwinding drum.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 6 The diagram shows that: a positioning groove 15 is chiseled at the right end of the base plate 1, and a positioning block 23 is provided inside the positioning groove 15. The positioning groove 15 is located directly below the unwinding roller. Both the positioning groove 15 and the positioning block 23 are inverted T-shaped. A positioning plate 16 is provided at the upper end of the base plate 1. The lower end of the positioning plate 16 is fixedly connected to the positioning block 23. An adjusting rod 17 is movably sleeved on the outer surface of the rightmost insert rod 12. The right end of the adjusting rod 17 movably passes through the positioning plate 16, and a ratchet 18 is fixedly sleeved on the outer surface of the adjusting rod 17. A pawl 19 is rotatably connected to the right end of the positioning plate 16. An inclined plate is also fixedly connected to the right end of the positioning plate 16. A compression spring 20 is fixedly connected between the inclined plate and the pawl 19. The ratchet 19 engages with the ratchet 18, causing the positioning plate 16 to fit against the rightmost short roller 5. At this time, the rightmost insert rod 12 moves through the positioning plate 16 and then inserts into the adjusting rod 17, causing the ratchet 18 to engage with the pawl 19. Rotating the adjusting rod 17 will cause the rightmost insert rod 12 to rotate, thereby driving multiple double-headed screws 6 to rotate. At the same time, the pawl 19 engages with the ratchet 18, making it difficult for the double-headed screws 6 to rotate on their own. If it is necessary to reset the adjusting plate 10, the pawl 19 can be pressed, causing the compression spring 20 to be squeezed, causing the pawl 19 to disengage from the ratchet 18, thereby allowing the ratchet 18 to rotate and adjusting the position of the adjusting plate 10.

[0030] Before winding the aluminum-plastic composite strip, the length of the unwinding roller can be adjusted according to the width of the aluminum-plastic composite strip. The limiting rod 14 can be inserted into the adjacent magnetic ring 13, causing the two magnetic rings 13 to attract and adhere to each other. The insert rod 12 is inserted into the adjacent double-headed screw 6, causing the two short rollers 5 to adhere to each other. This allows for the installation and splicing of the two short rollers 5 and the two double-headed screws 6, thereby adjusting the length of the unwinding roller. Then, the positioning block 23 is positioned within the positioning groove 15, pushing the positioning plate 16 towards the unwinding roller, causing the positioning plate 16 to adhere to the rightmost short roller 5. At this point, the rightmost insert rod 12 moves through the positioning plate 16. Insert the adjusting rod 17 to engage the ratchet 18 with the pawl 19. Rotating the adjusting rod 17 will cause the rightmost insert rod 12 to rotate, thereby driving multiple double-headed screws 6 to rotate. The rotation of the double-headed screws 6 will cause the two sliders 8 to move towards or away from each other on the surface of the double-headed screws 6, thereby causing the rotating rod 11 to rotate. Adjust the distance between the adjusting plate 10 and the short roller 5, so that the adjusting plate 10 fits against the inner wall of the unwinding drum. This allows the unwinding roller to be adjusted according to the actual specifications of the aluminum-plastic composite belt, effectively preventing shaking or deviation of the unwinding device during use, and thus effectively improving the stability of the unwinding device during use.

[0031] Second implementation method:

[0032] This embodiment adds a rubber pad 22 to the first embodiment, while the rest remains the same as the first embodiment.

[0033] Figure 7 As shown: A rubber pad 22 is fixedly connected to the end of the adjusting plate 10 away from the rotating rod 11, and multiple rubber protrusions are fixedly connected to the end of the rubber pad 22 away from the adjusting plate 10.

[0034] When the adjusting plate 10 is in contact with the inner wall of the unwinding drum wrapped with aluminum-plastic composite tape, the rubber pad 22 and the rubber protrusion are in close contact with the inner wall of the unwinding drum, thereby effectively increasing the friction between the adjusting plate 10 and the inner wall of the unwinding drum, and thus effectively improving the stability of the unwinding roller when it rotates.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
