Description

Technical Field

[0001] This utility model relates to the field of slitting machines, specifically to an automatic deviation correction device for a tape slitting machine. Background Technology

[0002] Tape slitting machines are used to cut wide tapes into narrow tapes of varying widths as needed. During operation, an unwinding shaft unwinds the wide tape; subsequently, a high-speed rotating cutter group cuts the arriving tape to a preset width, forming multiple narrow tapes; finally, each narrow tape is rewound by a take-up shaft. However, during the slitting process of wide tapes, due to equipment vibration or other factors, the wide tape is prone to shifting during its forward movement, thus affecting the subsequent slitting accuracy. Utility Model Content

[0003] Based on this, and in response to the above problems, this utility model provides an automatic deviation correction device for a tape slitting machine.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] An automatic correction device for a tape slitting machine is installed on the travel path of a wide tape and includes a first correction mechanism and a second correction mechanism arranged sequentially. The first correction mechanism includes a base, a movable frame mounted on the base, and a first edge-measuring sensor mounted on the base for detecting the edge of the tape. A drive assembly for driving the movable frame to move left and right along the surface of the base is connected to one side of the movable frame, and a plurality of first guide rollers are arranged on the movable frame. The second correction mechanism includes a correction platform, a swing drive assembly located below the correction platform for driving the correction platform to swing horizontally left and right, and a second edge-measuring sensor located in front of the correction platform. Two correction guide rollers are arranged at intervals along the travel path of the wide tape on the correction platform, and a pressure roller is located between the two correction guide rollers. The device also includes a controller, and the drive assembly, the first edge-measuring sensor, the swing drive assembly, and the second edge-measuring sensor are all electrically connected to the controller.

[0006] The above technical solution first uses a first correction mechanism to correct the position of the wide tape, returning it to its correct position. Specifically, the wide tape moves forward to the first correction mechanism, where a first edge sensor monitors its edge position in real time and transmits the signal to the controller. Based on the received signal, the controller activates a drive assembly, moving the moving frame left and right to adjust the tape's position, ensuring it is in the correct location. The wide tape then moves forward to a second correction mechanism, where its position is corrected again, further improving accuracy. Specifically, a second edge sensor monitors even the slightest deviation of the tape in real time and transmits the signal to the controller. Based on the signal, the controller activates a rotating assembly, driving the correction platform to swing left and right, precisely adjusting the tape's position and ensuring it remains on the preset path throughout its forward movement, thus improving product quality and production efficiency.

[0007] In a specific embodiment of this utility model: a pair of guide rails are installed on the upper surface of the base, a slider is connected to the guide rails, and the movable frame is fixed on the slider.

[0008] In a specific embodiment of this utility model: the tape slitting machine has a frame located in front of the movable frame, the second correction mechanism is installed on the frame, and a rotating shaft driven by a motor is provided on the front side of the frame above the second correction mechanism, and cutters arranged at equal intervals are sleeved on the rotating shaft.

[0009] In a specific embodiment of this utility model: a plurality of second guide rollers are provided on the frame.

[0010] In summary, this invention first uses a first correction mechanism to correct the position of the wide tape, bringing the offset wide tape back to the correct position. Then, a second correction mechanism corrects the position of the wide tape a second time, further improving the correction accuracy and ensuring that the wide tape stays on the preset travel path during the forward movement, thereby improving the cutting accuracy and production efficiency. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] Figure 1 This is a schematic diagram of the structure of an automatic correction device for a tape slitting machine according to this utility model. Detailed Implementation

[0013] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1 As shown, this utility model is an automatic correction device for a tape slitting machine, installed on the travel path of a wide tape 9, including a first correction mechanism 10 and a second correction mechanism 20 arranged sequentially. The first correction mechanism first corrects the position of the wide tape, returning it to the correct position. The second correction mechanism then corrects the position of the wide tape again, further improving the correction accuracy.

[0015] The first correction mechanism 10 includes a base 11, a movable frame 12 mounted on the base 11, and a first edge-measuring sensor mounted on the base 11 for detecting the edge of the wide tape 9. A drive assembly 14 is connected to one side of the movable frame 12, driving the frame 12 to move left and right along the upper surface of the base. Multiple first guide rollers 15 are arranged on the movable frame 12, and the wide tape sequentially passes over all the first guide rollers 15. In this embodiment, the drive assembly 14 is a cylinder drive assembly.

[0016] In this embodiment, a pair of guide rails 16 are mounted on the upper surface of the base 11. A slider 17 is connected to the guide rails 16. The movable frame 12 is fixed to the slider 17.

[0017] Additionally, the second correction mechanism 20 includes a correction platform 21, a swing drive assembly 22 located below the correction platform 21 for driving the correction platform 21 to swing horizontally left and right, and a second edge sensor 23 located in front of the correction platform 21 for detecting the edge of the wide tape 9. Two correction guide rollers 24 are spaced apart on the correction platform 21 along the travel path of the wide tape 9, and a pressure roller 25 is located between the two correction guide rollers 24. The wide tape 9 passes around the correction guide rollers 24 and the pressure roller 25.

[0018] It also includes a controller (not shown in the figure). The drive assembly 14, the first side-measuring sensor, the swing drive assembly 22, and the second side-measuring sensor 23 are all electrically connected to the controller.

[0019] In this way, the wide tape 9 moves forward to the first correction mechanism 10. The edge position of the wide tape 9 is monitored in real time by the first edge-measuring sensor, and the signal is transmitted to the controller. Based on the received signal, the controller controls the drive assembly 14 to start, driving the moving frame 12 to move left and right to adjust the position of the wide tape, so that the offset wide tape returns to the correct position. The wide tape continues to move forward to the second correction mechanism 20, which further improves the correction accuracy. Specifically, the second edge-measuring sensor 23 monitors the slight offset of the wide tape in real time and transmits the signal to the controller. Based on the signal, the controller controls the swing drive assembly 22 to start, driving the correction platform to swing left and right, thereby precisely adjusting the position of the wide tape 9 and ensuring that the wide tape 9 always stays on the preset travel path during the forward movement, thereby improving the accuracy and efficiency of subsequent slitting.

[0020] The tape slitting machine has a frame 8 located in front of a movable frame. A second web guiding mechanism 20 is mounted on this frame 8. A motor-driven rotating shaft 7 is located on the front side of the frame 8 above the second web guiding mechanism 20, and equally spaced cutters are mounted on the rotating shaft 7. Multiple second guide rollers 6 are located on the frame 8 behind the second web guiding mechanism.

[0021] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
