Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, and in particular to a quick-change positioning structure for tape rolls. Background Technology

[0002] Adhesive tape rolls refer to products where adhesive tape material is wound into a roll for easy storage and use. Adhesive tape rolls have a wide range of applications, commonly found in offices, packaging, industry, and homes. Positioning structures are design structures in machinery and equipment used to ensure that objects and components remain stable and precisely aligned in specific positions. Their main function is to help components and objects be correctly positioned during assembly, operation, and handling, ensuring the accuracy, reliability, and safety of the entire system.

[0003] Tape roll devices are typically designed with a fixed installation method, securely mounting the tape roll on a bracket and support to ensure that the tape roll remains in a stable position during use. During operation, the tape is guided to the surface to be pasted via guide wheels and guide rails. As the tape is pulled, the roll automatically rotates to ensure a smooth supply of tape and facilitate the pasting operation.

[0004] In the prior art, some tape roll devices are usually installed in a fixed manner. Users need to spend a lot of time and effort to disassemble and reinstall when changing tape. This not only increases the complexity of operation, but also leads to tape damage or waste, thus affecting the overall user experience. To solve the above problems, a quick tape roll replacement positioning structure is proposed. Utility Model Content

[0005] The tape roll quick-change positioning structure proposed in this utility model aims to improve the problem that some devices in the prior art cannot be changed quickly.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-change positioning structure for tape rolls includes a fixed support frame. A drive assembly providing left and right pushing force is fixedly connected to the inner center of the fixed support frame. A sliding connecting ring is fixedly connected to the drive assembly. Multiple first fixed connecting blocks are fixedly connected to the outer side of the sliding connecting ring. First rotating connecting plates are rotatably connected to the left and right sides of each of the first fixed connecting blocks. An arc-shaped fixed support plate is rotatably connected to the outer side of two of the first rotating connecting plates, which is closer to each other. A fixed connecting plate is fixedly connected to the top of the fixed support frame. A support connecting column is fixedly connected to the bottom of the fixed connecting plate. Multiple second fixed connecting blocks are fixedly connected to both ends of the support connecting column. Second rotating connecting plates are rotatably connected to the left and right sides of each of the second fixed connecting blocks. The outer side of two of the second rotating connecting plates, which is closer to each other, is rotatably connected to the left and right sides of the arc-shaped fixed support plate.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a cylinder, the bottom of which is fixedly connected to the inner middle of the fixed support base, and the drive end of the cylinder is fixedly connected to a connecting telescopic column. A connecting transfer plate frame is fixedly connected to the outside of the connecting telescopic column.

[0010] As a further description of the above technical solution:

[0011] A support connecting plate is fixedly connected to the outer middle of the fixed support base, a power component that provides rotational power is fixedly connected to the top of the support connecting plate, and a fixed limiting ring is fixedly connected to the outer middle of the fixed support base.

[0012] As a further description of the above technical solution:

[0013] The power assembly includes a motor, the bottom of which is fixedly connected to the outer middle of the fixed support base, and the drive end of the motor is fixedly connected to a rotating connecting shaft.

[0014] As a further description of the above technical solution:

[0015] A rotating connecting disk is fixedly connected to the outside of the rotating connecting shaft, and a limit transmission column is fixedly connected to the outside of the rotating connecting disk.

[0016] As a further description of the above technical solution:

[0017] The rotating connecting disc is slidably connected to a rotating transmission plate, the rotating transmission plate is fixedly connected to a sliding connecting column, and the sliding connecting column is fixedly connected to a cutting blade.

[0018] As a further description of the above technical solution:

[0019] The external of the connecting transmission plate frame is fixedly connected to the outside of the sliding connecting ring, and the internal of the sliding connecting ring is slidably connected to the outside of the supporting connecting column.

[0020] As a further description of the above technical solution:

[0021] The inside of the rotating transmission plate is slidably connected to the outside of the limiting transmission column, and the outside of the sliding connection column is slidably connected to the outside of the rotating connection disc.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the connecting telescopic column is pushed outward by the starting cylinder, so that the sliding connecting ring slides outside the supporting connecting column. Because the sliding connecting ring is connected to the outside of the first rotating connecting plate, the sliding force is converted into the rotational force by the first rotating connecting plate, which pushes the arc-shaped fixed support plate to move outward. The force is transmitted to the second rotating connecting plate through the arc-shaped fixed support plate, so that the rotation of the second rotating connecting plate also pushes the arc-shaped fixed support plate to move outward, thus achieving the effect of fast and accurate positioning and replacement of tape roll.

[0024] 2. In this utility model, the starting motor drives the rotating connecting shaft to rotate, causing the rotating connecting disc to rotate. Under the rotational transmission of the rotating connecting disc, the rotating transmission plate drives the sliding connecting column to slide outside the rotating connecting disc. Because the movement trajectory of the sliding connecting column is restricted by the fixed limiting ring, the rotational force is converted into left-right reciprocating motion, thereby automatically cutting the film roll with the cutting blade, improving work efficiency.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a quick-change positioning structure for adhesive tape rolls, including a fixed support frame 1. The frame is rectangular in shape and can withstand the weight of the various components and the forces generated during operation, ensuring that the fixed support frame 1 will not deform or be damaged during long-term use. A drive assembly providing left and right pushing force is fixedly connected to the middle of the fixed support frame 1. The drive assembly includes a cylinder 2, which is cylindrical in shape and contains key components such as a piston and cylinder body. Compressed air input and output drive the piston to perform linear reciprocating motion. The bottom of the cylinder 2 is fixedly connected to the middle of the fixed support frame 1. The drive end is fixedly connected to a connecting telescopic column 3, which is a slender cylindrical shape and made of high-strength alloy steel. It has good strength and wear resistance and can withstand the tension and pressure generated when the cylinder 2 drives it, ensuring that it will not deform or be damaged during long-term use. The connecting telescopic column 3 is fixedly connected to a connecting transfer plate frame 4. The connecting transfer plate frame 4 is a rectangular plate structure. Its movement is controlled by the cylinder 2. By moving left and right, it drives the sliding connecting ring 5 to make corresponding position adjustments. The connecting transfer plate frame 4 is fixedly connected to the outside of the sliding connecting ring 5, and the inside of the sliding connecting ring 5 is slidably connected to the outside of the supporting connecting column 10.

[0033] The drive assembly is fixedly connected to a sliding connecting ring 5. The sliding connecting ring 5 is circular and made of wear-resistant metal, such as stainless steel, which has good strength and wear resistance, and can slide smoothly on the supporting connecting column 10. Multiple first fixed connecting blocks 6 are fixedly connected to the outside of the sliding connecting ring 5. The first fixed connecting blocks 6 are cuboid blocks made of carbon steel and are firmly and reliably connected to the sliding connecting ring 5. They are used to connect and support the first rotating connecting plate 7. The first fixed connecting blocks 6 are rotatably connected to the left and right sides of the first rotating connecting plate 7. The first rotating connecting plate 7 is elongated and can be rotated to adjust the position and angle of the arc-shaped fixed support plate 8 to accommodate different specifications of adhesive. For fixing and replacing the tape roll, an arc-shaped fixing support plate 8 is rotatably connected to the outer side of the two first rotating connecting plates 7, i.e., the side furthest from the two first rotating connecting plates 7. The arc-shaped fixing support plate 8 is an arc-shaped plate that matches the outer contour of the tape roll. Under the drive of the first rotating connecting plates 7, the arc-shaped fixing support plate 8 will rotate around the connecting axis with the first rotating connecting plates 7. The rotation realizes the fixing and loosening operation of the tape roll, meeting the needs of different working conditions. A fixing connecting plate 9 is fixedly connected to the top of the fixing support base 1. The fixing connecting plate 9 is a rectangular plate and is made of carbon steel, the same material as the fixing support base 1, to ensure the stability of the connection.

[0034] A support connecting column 10 is fixedly connected to the bottom of the fixed connecting plate 9. The support connecting column 10 is a slender cuboid shape and is made of high-strength stainless steel. It has good strength and wear resistance and can withstand the friction and pressure generated when the sliding connecting ring 5 slides on it, ensuring the stable operation of the device. Multiple second fixed connecting blocks 11 are fixedly connected to both ends of the support connecting column 10. The second fixed connecting blocks 11 are cuboid blocks made of carbon steel and are firmly and reliably connected to the support connecting column 10. They are used to connect and support the second rotating connecting plate 12. The second rotating connecting plate 12 is long and narrow. By rotating, it helps to adjust the position and angle of the arc-shaped fixed support plate 8, further ensuring the stable fixing and replacement of the tape roll. The second rotating connecting plates 12 are rotatably connected to both sides of the second fixed connecting blocks 11. The side of the two second rotating connecting plates 12 that is close to each other, i.e. the side away from the two second rotating connecting plates 12, is rotatably connected to the left and right sides of the arc-shaped fixed support plate 8.

[0035] Reference Figure 1 , Figure 2 and Figure 4A support connecting plate 13 is fixedly connected to the outer middle of the fixed support base 1. The support connecting plate 13 is rectangular and made of carbon steel, the same material as the fixed support base 1, ensuring the stability of the connection. A power component providing rotational power is fixedly connected to the top of the support connecting plate 13. The power component includes a motor 14, which is generally rectangular in shape. The internal motor windings are made of high-quality copper wire, which has good conductivity and can effectively improve the working efficiency of the motor 14. The bottom of the motor 14 is fixedly connected to the fixed support base 1. At the outer middle of the support base 1, the drive end of the motor 14 is fixedly connected to a rotating connecting shaft 15. The rotating connecting shaft 15 is a slender cylindrical shape with high strength and good wear resistance. It can withstand the torque and centrifugal force generated when the motor 14 is driven, ensuring that it will not deform or be damaged during long-term use. At the outer middle of the fixed support base 1, a fixed limiting ring 21 is fixedly connected. The fixed limiting ring 21 is circular and is used to limit the axial displacement of the sliding connecting column 19, ensuring that the sliding connecting column 19 converts the rotational force into the force of left and right movement.

[0036] A rotating connecting disc 16 is fixedly connected to the outside of the rotating connecting shaft 15. Driven by the rotating connecting shaft 15, the rotating connecting disc 16 rotates at high speed around the axis of the rotating connecting shaft 15, its motion trend being circular motion, providing power output for the rotational action of the entire device. The rotating connecting disc 16 is a circular plate. A limiting transmission post 17 is fixedly connected to the outside of the rotating connecting disc 16. The limiting transmission post 17 is a slender cylindrical shape, made of alloy steel, with good strength and wear resistance, used to cooperate with the rotating transmission plate 18 to achieve limiting and power transmission of the rotating transmission plate 18. The rotating transmission plate 18 is slidably connected to the outside of the rotating connecting disc 16. The rotating transmission plate 18 is a rectangular plate, and its interior is formed by opening... The sliding hole of the sliding plate 18 is engaged with the outside of the limiting transmission post 17 to achieve a sliding connection and transmit force to the sliding connecting post 19. The inside of the rotating transmission plate 18 is slidably connected to the outside of the limiting transmission post 17, and the outside of the sliding connecting post 19 is slidably connected to the outside of the rotating connecting disc 16. The outside of the rotating transmission plate 18 is fixedly connected to the sliding connecting post 19. The sliding connecting post 19 is in the shape of a slender cylinder and is used to transmit the rotational force of the rotating transmission plate 18. Under the restriction of the fixed limiting ring 21, the rotational force is converted into a left and right sliding force. The outside of the sliding connecting post 19 is fixedly connected to the cutting blade 20. The cutting blade 20 is in the shape of a sharp sheet. The cutting blade 20 slides left and right under the drive of the sliding connecting post 19 to cut the old tape and facilitate the replacement of the new tape roll.

[0037] Working principle: First, cylinder 2 is activated, causing compressed air to be input and output, driving the connecting telescopic column 3 to move left and right, thereby driving the movement of the connecting transmission plate frame 4, and then causing the sliding connecting ring 5 to slide on the supporting connecting column 10. Multiple first fixed connecting blocks 6 are fixedly connected to the outside of the sliding connecting ring 5. These blocks adjust the position and angle of the arc-shaped fixed support plate 8 by rotating the first rotating connecting plate 7, and transmit force to the second rotating connecting plate 12 through the arc-shaped fixed support plate 8. The rotation of the second rotating connecting plate 12 also pushes the arc-shaped fixed support plate 8 outward to accommodate the fixing and replacement of tape rolls of different specifications. At the top of the fixed support base frame 1, the cooperation between the fixed connecting plate 9 and the supporting connecting column 10 ensures the stability of the entire device.

[0038] Motor 14 starts, driving the rotary connecting shaft 15 to rotate, which in turn drives the rotary connecting disc 16 to rotate at high speed. The rotation of the rotary connecting disc 16 is transmitted to the rotary transmission plate 18 through the limit transmission column 17. The rotary transmission plate 18 slides left and right under the drive of the sliding connecting column 19. At this time, a cutting blade 20 is fixedly connected to the outside of the sliding connecting column 19. The cutting blade 20 cuts the old tape during the sliding process, making it easy to replace the new tape roll.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
