Description

Technical Field

[0001] This utility model relates to the technical field of tape cutting equipment, and in particular to a Teflon tape fixed-distance cutting device. Background Technology

[0002] Teflon tape is widely used in electronics, chemical, and aerospace industries due to its excellent high-temperature resistance, corrosion resistance, and low coefficient of friction. In practical applications, Teflon tape often needs to be cut to a certain length. Currently, most existing Teflon tape cutting methods involve manual measurement and cutting. This method is not only inefficient, but also prone to errors due to manual measurement and cutting, making it difficult to guarantee the accuracy of the cut tape length. This method cannot meet the requirements of some application scenarios with high tape length accuracy.

[0003] A search revealed a Chinese patent publication number CN222794800U that discloses a tape cutting machine. This tape cutting machine includes a tape feeding mechanism, a tape clamping mechanism, and a cutting mechanism. The tape feeding mechanism continuously supplies tape, and the clamping mechanism holds the tape and moves it in a preset direction until it reaches the target position. Then, the cutting mechanism cuts the tape into a target length. After cutting, the tape clamping mechanism moves in the opposite direction to clamp a new section of tape. In this way, multiple tape cuttings can be achieved through the cyclical movement of the clamping mechanism. In addition, the length of the tape cut each time can be changed by controlling the length of the tape between the clamping mechanism and the cutting mechanism. This eliminates the need to design multiple different devices for different tape lengths, thereby improving production efficiency and reducing costs.

[0004] The above-mentioned and existing related technologies often have the following drawbacks: Although multiple cuttings can be achieved through the cyclic reciprocating motion of the clamping mechanism, it is difficult to quickly and flexibly adjust the cutting width when cutting Teflon tape, and it cannot meet the cutting needs of Teflon tapes of different widths.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figures 1-5 As shown, this utility model provides a technical solution: a Teflon tape fixed-distance cutting device, including: a workbench 1, a guide component 2 is provided on one side of the workbench 1, a transmission component 5 and a receiving component 7 are provided on the upper end of the workbench 1, a slider 8 is sleeved on the outer surface of the transmission component 5, a telescopic column 9 is provided on the upper end of the slider 8, and a cutting component 6 is provided on one side of the telescopic column 9.

[0024] The cutting component 6 includes a U-shaped plate 61 disposed on one side of the telescopic column 9. A groove 62 is formed on the inner wall of the U-shaped plate 61. A sliding rod 64 is disposed inside the groove 62. A sliding block 68 is slidably fitted onto the outer surface of the sliding rod 64. The sliding block 68 is engaged inside the groove 62. A cutting blade 63 is fixed to the lower end of the sliding block 68. An opening groove 65 is formed at one end of the U-shaped plate 61, communicating with the groove 62. A bolt 66 is disposed inside the opening groove 65, and the bolt 66 is threadedly connected to the sliding block 68. A scale 67 is provided at the end of the U-shaped plate 61 near the guide component 2. When it is necessary to cut the Teflon tape, a scale 67 is provided. As needed, loosen bolt 66 and push sliding block 68 to slide along slide rod 64. Determine the lateral distance between cutter 63 and conveyor belt direction using scale 67. By cooperating with scale 67 and bolt 66, the position of cutter 63 can be precisely adjusted to meet different width requirements. After determining the cutting width, tighten bolt 66 to fix sliding block 68 and ensure that the position of cutter 63 remains unchanged. Telescopic column 9 drives cutter 63 to move downward. Cutter 63 cuts conveyor belt at preset position to achieve fixed-distance cutting. The cutting width can be set by manually adjusting sliding block 68, making the cutting width flexibly adjustable and improving operation convenience.

[0025] Reference Figure 2As shown in this embodiment: the guide component 2 includes a support rod 22 disposed on one side of the workbench 1. There are two sets of support rods 22, and a rotating shaft is rotatably connected between the two sets of support rods 22. A first motor 21 is disposed on the outer surface of one set of support rods 22. The output end of the first motor 21 passes through the support rod 22 and is fixedly connected to the rotating shaft. A Teflon tape roll 23 is sleeved on the outer surface of the rotating shaft. The zero mark of the scale 67 corresponds to one end of the Teflon tape roll 23. After the first motor 21 is energized, it outputs torque to drive the rotating shaft to rotate, thereby driving the Teflon tape roll 23 sleeved on the rotating shaft to rotate. By controlling the speed and number of rotations of the first motor 21, the quantitative conveying of the tape is realized.

[0026] The upper end of the workbench 1 is provided with a first support block 11 and a second support block 12. There are two sets of the first support block 11 and the second support block 12. A tension component 3 is provided between the first support block 11 and the second support block 12. The tension component 3 includes a tension roller 32 rotatably connected between one set of the first support block 11 and the second support block 12. A second motor 31 is provided at one end of the first support block 11. The output end of the second motor 31 passes through the first support block 11 and is fixedly connected to the tension roller 32. When the Teflon tape roll 23 rotates, the tape is gradually released from the outside of the roll and extends along the worktable 1. It passes the upper end of the tension roller 32. The second motor 31 outputs torque according to the tape's running state, driving the tension roller 32 to rotate. When the tape unwinds too quickly, causing slack, the second motor 31 drives the tension roller 32 to accelerate and tighten the tape. If the tape is too tight, the second motor 31 can decelerate or make fine adjustments in the opposite direction to prevent the tape from wrinkling or piling up due to slack during transmission, ensuring a flat tape surface and providing a stable material state for subsequent flattening, cutting, and other processes.

[0027] A flattening component 4 is provided between the first support block 11 and the second support block 12. The flattening component 4 is provided in two sets. The flattening component 4 includes a flattening roller 41 disposed between the first support block 11 and the second support block 12. The two ends of the flattening roller 41 are rotatably connected to moving blocks 42. A cavity is opened on one side of the first support block 11 and the second support block 12. The moving block 42 is located inside the cavity. An electric push rod 43 is fixed to the upper end of the moving block 42. The electric push rod 43 is fixedly connected to the inner wall of the cavity. When the electric push rod 43 is energized, it extends and retracts, driving the moving block 42 to move up and down in the cavity, so that the flattening roller 41 approaches or moves away from the surface of the worktable 1. When the tape passes under the flattening roller 41, the electric push rod 43 pushes the flattening roller 41 down, using the roller surface pressure to press the tape tightly against the worktable 1, eliminating wrinkles or curling. For tapes of different thicknesses, the downward pressure of the flattening roller 41 can be adjusted in real time by the electric push rod 43 to avoid excessive pressure causing tape deformation or insufficient pressure causing poor flattening effect.

[0028] Reference Figure 3As shown in this embodiment: the transmission component 5 is provided in two sets. Each set of transmission components 5 includes a sliding rod 51 and a threaded rod 52 disposed between two sets of first support blocks 11 and two sets of second support blocks 12. The outer surfaces of the sliding rod 51 and the threaded rod 52 are sleeved and connected to the slider 8. The upper end of the slider 8 is fixedly connected to the telescopic column 9, and one side of the telescopic column 9 is fixedly connected to the U-shaped plate 61. A third motor 54 is provided at one end of one set of first support blocks 11. The output end of the third motor 54 is fixedly connected to one set of the threaded rods 52. A fourth motor 53 is provided at one end of the second support block 12. The output end of the fourth motor 53 is fixedly connected to another set of threaded rods 52. After the third motor 54 and the fourth motor 53 are powered on, they rotate synchronously, driving the corresponding threaded rods 52 to rotate. When the threaded rods 52 rotate, the slider 8 moves along the axial direction of the threaded rods 52 due to the thread transmission principle. At the same time, the sliding rod 51 provides guidance for the slider 8 to avoid rotational deviation. The movement of the slider 8 drives the telescopic column 9 and the U-shaped plate 61 to move laterally, thereby adjusting the lateral position of the cutting blade 63 on the worktable 1 and realizing precise control of the cutting position.

[0029] The receiving component 7 includes a receiving roller 71 disposed between one of the first support blocks 11 and the second support blocks 12. A fifth motor 73 is disposed at one end of the second support block 12. The output end of the fifth motor 73 is fixedly connected to the receiving roller 71. A tape roller 72 is sleeved on the outer surface of the receiving roller 71. When the fifth motor 73 is powered on, it rotates, driving the receiving roller 71 to rotate. The tape roller 72 rotates synchronously with the receiving roller 71. The front end of the cut tape is manually fixed on the surface of the tape roller 72. When the receiving roller 71 rotates, it winds the tape by friction to form a neat roll. The speed of the fifth motor 73 is matched with the tape conveying speed to avoid the tape from breaking due to excessive speed or stacking due to excessive speed.

[0030] Working Principle: The Teflon tape fixed-distance cutting device is based on the worktable 1. Each component works collaboratively to cut the tape. First, the first motor 21 starts, driving the rotating shaft to rotate, causing the Teflon tape roll 23 on the shaft to rotate. The tape is gradually released from the outside of the roll and extends along the worktable 1, completing the initial conveying of the tape. The released tape passes over the upper surface of the tension roller 32. The second motor 31 adjusts the rotation of the tension roller 32 in real time according to the tape's running status. When the tape unwinds too quickly and becomes slack, the second motor 31 drives the tension roller 32 to accelerate its rotation, tightening the tape. If the tape is too tight, the second motor 31 will decelerate or make fine adjustments in the reverse direction to ensure that the tape maintains appropriate tension and a flat surface during transmission. Next, the tape enters the flattening component 4 area. The electric push rod 43 adjusts the position of the flattening roller 41 according to the tape thickness. When the tape passes under the flattening roller 41, the electric push rod 43 pushes the flattening roller 41 downwards, using the roller surface pressure to press the tape tightly against the worktable 1, eliminating wrinkles or warping, and providing a flat material for subsequent cutting. Then, the transmission component 5 begins to function, with the third motor 54 and the fourth motor 53 rotating synchronously, driving the threaded rod 52. Rotation occurs because the slider 8 is sleeved with the threaded rod 52. Under the principle of threaded transmission, the slider 8 moves axially along the threaded rod 52. At the same time, the sliding rod 51 provides guidance for the slider 8. The movement of the slider 8 drives the telescopic column 9 and the U-shaped plate 61 to move laterally, thereby precisely adjusting the lateral position of the cutting blade 63 on the worktable 1. After adjusting the position of the cutting blade 63, if it is necessary to change the cutting width, it can be achieved through the cutting component 6. Loosen the bolt 66, push the sliding block 68 to slide along the sliding rod 64, and use the scale 67 to determine the lateral distance between the cutting blade 63 and the conveyor belt direction, thus precisely adjusting the cutting width. The position of the cutter 63 is adjusted to accommodate different width requirements. After adjustment, the bolt 66 is tightened to fix the sliding block 68. When everything is ready, the telescopic column 9 drives the cutter 63 to move downward and cut the tape at the preset position to complete the fixed-distance cutting. Finally, the fifth motor 73 starts, driving the take-up roller 71 to rotate. The tape roller 72 rotates synchronously. The cut tape front end is fixed on the surface of the tape roller 72 by hand. When the take-up roller 71 rotates, it winds the tape by friction to form a neat roll. The speed of the fifth motor 73 is matched with the tape conveying speed to ensure the smooth progress of the take-up process.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
