Description

Technical Field

[0001] This utility model relates to the field of cutting devices, and in particular to an anti-deviation cutting device for high weather-resistant PET double-sided adhesive. Background Technology

[0002] PET double-sided tape is made by coating PET with acrylic adhesive on both sides. In the production of double-sided tape, in order to cut the double-sided tape into the appropriate size, it needs to be cut. Conventional cutting is divided into transverse and longitudinal cutting. Transverse cutting is to cut PET double-sided tape into equal lengths, while longitudinal cutting is to cut it into strips of different widths by a cutting device.

[0003] However, the existing anti-deviation cutting device for high weather-resistant PET double-sided tape has extremely high requirements for cutting accuracy. Currently, deviation during tape conveying will cause inaccurate cutting dimensions, affecting product size. At the same time, the cutting blade needs to contact the tape, which makes the blade surface prone to adhesive residue, affecting the flatness of the cutting edge, and it is also easy to form adhesion with the tape, thus affecting cutting accuracy.

[0004] Therefore, in order to solve the above problems, we propose an anti-deviation cutting device for high weather-resistant PET double-sided tape to prevent deviation during tape conveying and ensure cutting accuracy. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Please see Figures 1-7 This utility model provides an embodiment of an anti-deviation cutting device for high weather-resistant PET double-sided tape, including a frame 1, and a feeding rack 2 and a winding rack 3 fixedly installed at the left and right ends of the frame 1, respectively. A feeding roller is rotatably installed on the inner side of the feeding rack 2, and a winding roller is rotatably installed on the inner side of the winding rack 3. A winding motor 31 is fixedly installed on the front end of the winding rack 3, and the output end of the winding motor 31 is fixedly connected to the front end of the winding roller. The winding motor 31 is used to drive the winding roller to rotate. A positioning roller is installed on the inner side of the winding rack 3, located next to the winding motor 31, to position and guide the double-sided tape. An offset rack 4 is installed on the inner side of the frame 1. A displacement component is provided between the upper end of the offset rack 4 and the top of the frame 1 to drive the offset rack 4 to move forward or backward. A pressure roller 5 is rotatably installed on the inner side of the offset rack 4. The pressure roller 5 consists of two rollers forming an upper and lower clamping clamp. A cutting component is provided on the left end of the inner side of the frame 1. A guide roller 6 is installed on the inner side between the cutting assembly and the offset frame 4. A detection assembly is set on the inner side of the frame 1, located on the side of the guide roller 6. The detection assembly is used to detect the position of the double-sided tape. A cleaning box 7 is set on the inner side of the frame 1, located on the top of the cutting assembly. The cutting assembly includes a rotating shaft 8 rotatably installed on the inner side of the frame 1. Cutting blades 9 are detachably installed on the surface of the rotating shaft 8. The cutting blades 9 are evenly distributed. A drive motor 10 is fixedly installed at the front end of the frame 1. The output end of the drive motor 10 is connected to the front end of the rotating shaft 8. The drive motor 10 is used to drive the rotating shaft 8 to rotate. The high weather-resistant PET double-sided tape enters the frame 1 through the feeding roller and is pressed and limited by two pressing rollers 5. The tape is cut into multiple strips by multiple cutting blades 9. The detection assembly confirms whether the tape is conveyed correctly. When a deviation occurs, the displacement assembly drives the offset frame 4 to move and adjust the conveying position of the tape to ensure the accuracy of the cutting.

[0030] Please see Figures 1-4In this embodiment, the displacement assembly includes a mounting plate 41 fixedly mounted on the top of the frame 1. A displacement box 42 is fixedly connected to the upper end of the mounting plate 41. A lead screw 43 is mounted inside the displacement box 42. A servo motor 44 is fixedly mounted at the front end of the displacement box 42. The output end of the servo motor 44 is fixedly connected to the front end of the displacement box 42. The servo motor 44 is used to drive the lead screw 43 to rotate. Guide rods 45 are fixedly connected to both sides of the lead screw 43 on the inner side of the displacement box 42. A displacement seat 46 is threaded onto the surface of the lead screw 43. When the lead screw 43 rotates, it drives the displacement seat 46 to move forward or backward. The two ends of the displacement seat 46 are slidably connected to the guide rods 45. A sliding groove is provided on the surface of the mounting plate 41. A slider 47 is slidably mounted in the sliding groove. The upper end of the slider 47 is fixedly connected to the displacement seat 46, and the lower end of the slider 47 is fixedly connected to the offset frame 4. The upper end of the offset frame 4 is fixedly connected, and the lower end of the offset frame 4 is slidably connected to the bottom of the frame 1 via a slide rail. The upper end of the offset frame 4 is slidably connected to the mounting plate 41 via a slide rail. The front side of the offset frame 4 is fixedly mounted with a support bracket. The output end of the conveyor motor 51 is connected to the front end of the pressure roller 5. The conveyor motor 51 is used to drive the pressure roller 5 to rotate. The speed of the conveyor motor 51 needs to be matched with the winding motor 31 so that the conveying and winding of the tape maintain the same speed, thereby maintaining the tension of the tape during conveying. The two pressure rollers 5 form a clamp. When rotating, the tape can be conveyed. At the same time, when the servo motor 44 drives the lead screw 43 to rotate, the displacement seat 46 drives the offset frame 4 to move, changing the position of the offset frame 4. Thus, the tape clamped by the pressure roller 5 moves synchronously, changing the position of the tape and preventing offset.

[0031] Please see Figure 6 and Figure 7 In this embodiment, the detection component includes a stop bar 61. An installation rod 62 is fixedly installed on the inner side of the frame 1. Two stop bars 61 are symmetrically arranged on both sides of the installation rod 62. The two stop bars 61 are respectively attached to both sides of the double-sided tape. Both stop bars 61 and the installation rod 62 are connected through a sensing module. The sensing module includes a positioning block 63 fixedly installed at the bottom of the stop bar 61. The installation rod 62 has a mounting cavity for sliding connection with the positioning block 63. A pressure sensor is installed in the mounting cavity. The pressure sensor and the positioning block 63 are connected by a buffer pad. The pressure sensor is used to sense the position of the positioning block 63. When the tape shifts, the stop bar 61 shifts synchronously, so that the pressure sensor in contact senses the pressure change. The pressure sensor and the servo motor 44 are both controlled by an external control terminal. So when the pressure changes, the control terminal starts the servo motor 44 to rotate accordingly, which can adjust the position of the offset frame 4 and prevent the tape from shifting.

[0032] Please see Figure 1 , Figure 5 and Figure 6In this embodiment, a cleaning groove is provided at the bottom of the cleaning box 7, and the cleaning groove and the cutting blade 9 correspond one-to-one. Cleaning sponges for wiping the cutting blade 9 are detachably installed at both ends of the inner side of the cleaning groove. A fixing groove 81 for guiding and positioning is provided on the surface of the rotating shaft 8. The cutting blade 9 is sleeved with the rotating shaft 8 through the blade holder, and a limiting block for sliding engagement with the fixing groove 81 is provided on the inner wall of the blade holder. A locking bolt for locking the limiting is threaded on the surface of the blade holder. The rotation of the cutting blade 9 facilitates cutting, and when the cutting blade 9 rotates, the cleaning sponge can wipe the blade surface simultaneously to remove any impurities that may stick, ensuring the cutting effect. The blade holder of the cutting blade 9 is slidably installed, which facilitates the adjustment of the spacing of the cutting blade 9.

[0033] During operation, high weather-resistant PET double-sided tape enters the frame 1 through the feeding roller, is pressed and limited by two clamping rollers 5, passes through the guide roller 6 and the detection component, and enters the take-up roller after the cutting blade 9. The take-up roller is controlled by a pressure sensor to sense the position of the positioning block 63. When the tape deviates, the stop bar 61 deviates synchronously, thereby contacting the pressure sensor to sense the pressure change. Both the pressure sensor and the servo motor 44 are controlled by an external control terminal. When the pressure changes, the control terminal starts the servo motor 44 to rotate accordingly, which can adjust the position of the offset frame 4 to prevent tape deviation. At the same time, the rotation of the cutting blade 9 facilitates cutting, and when the cutting blade 9 rotates, the cleaning sponge can wipe the blade surface simultaneously to remove any possible adhering impurities, ensuring the cutting effect. The blade holder of the cutting blade 9 is slidably installed, which makes it easy to adjust the spacing of the cutting blade 9.

[0034] Through the above steps, the high weather-resistant PET double-sided tape enters the frame 1 through the feeding roller and is clamped and limited by two clamping rollers 5. Multiple cutting blades 9 are used to cut the tape into multiple strips. The detection component confirms whether the tape is conveyed correctly. When deviation occurs, the displacement component drives the offset frame 4 to move and adjust the tape conveying position to ensure the accuracy of cutting. This solves the problem of inaccurate cutting size caused by deviation during tape conveying.
