[0003] In existing technologies, traditional BOPET winding electrostatic adsorption devices typically use a localized electrostatic field on the winding roller to electrostatically adsorb and fix materials such as textiles, paper, and plastic films. This means that during automatic roll changing, traditional winding devices usually adjust the winding roller speed to accommodate different materials. However, this adjustment method often requires numerous sensors, leading to significant manpower and resources needed for setup. This, in turn, affects the efficiency of winding different materials and increases adjustment costs. Therefore, this invention proposes a BOPET winding electrostatic adsorption device to solve the problems existing in the prior art. Utility Model Content

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-7This utility model provides an embodiment of a BOPET winding electrostatic adsorption device, including a base 3, a CNC table 2, an electrostatic generator 9, an electrostatic sensor 17, a first roller 12, and a second roller 18. Moving wheels 6 are fixed to the four corners of the lower end of the base 3. The CNC table 2 and a first support plate 4 are fixed to the upper edge of the base 3. An electrostatic box 8 is installed at the front end of the CNC table 2. A cabinet door 10 is hinged to the inner wall of the front end of the electrostatic box 8. The electrostatic generator 9 is installed inside the electrostatic box 8. A second support plate 5 is fixed to the front and rear edges of the electrostatic box 8. A servo motor 11 is installed inside the CNC table 2. A second roller 18 is installed on the output end. Several sets of second electrodes 21 are installed on the outer wall of the second roller 18, which are distributed at equal intervals around the outer wall of the second roller 18. Two sets of first rollers 12 are rotatably installed between the second support plate 5 and the first support plate 4 at the right end of the electrostatic box 8. Several sets of first electrodes 15 are fixedly connected to the outer wall of the first roller 12, which are distributed at equal intervals around the first roller 12. An electrical isolation cover 1 is fixedly connected to the upper edge of the base 3. The top of the electrical isolation cover 1 can be rotated and opened and closed. An alarm light 7 is installed on the upper edge of the electrostatic box 8. The alarm light 7 passes through the electrical isolation cover 1 and is exposed at the upper end of the electrical isolation cover 1.

[0026] A set of support plates 16 are installed between the second support plate 5 and the first support plate 4 at the right end of the electrostatic box 8. An electrostatic sensor (17) is installed on the support plate 16.

[0027] This invention, through the electrostatic generator 9, the first electrode 15 and the second electrode 21, in conjunction with the first roller 12 and the second roller 18, can uniformly apply an electrostatic field to both the upper and lower surfaces of the material. At the same time, it can also apply an electrostatic field to the second roller 18 to perform efficient and stable automatic roll changing on the end of the material to which the electrostatic field has been applied. The electrostatic sensor 17 can detect the electrostatic data on the material in real time, so as to adjust the intensity of the electrostatic field generated by the electrostatic generator 9 according to the different materials.

[0028] Please see Figures 5-6In this embodiment, a first isolation sleeve 13 is fitted onto the outer wall of the first roller 12. The first isolation sleeve 13 is made of rubber. Several sets of first through holes 14 are equidistantly distributed around the outer wall of the first isolation sleeve 13. The rubber first isolation sleeve 13 can also increase the friction of the material driven by the first roller 12. The first electrode 15 passes through the first through hole 14 and is located at the center of the inner wall of the first through hole 14. The outer wall of the first electrode 15 is in contact with the inner wall of the first through hole 14. The first isolation sleeve 13, in conjunction with the first through hole 14, can help the material adhere to the outer walls of the two sets of first isolation sleeves 13, and not to the first electrode 15. In direct contact, the outer wall of the second roller 18 is fitted with a second isolation sleeve 19, which is made of rubber. The outer wall of the second isolation sleeve 19 has several sets of second through holes 20 that are equidistantly distributed around the outer wall of the second isolation sleeve 19. The rubber material of the second isolation sleeve 19 can also increase the friction force of the second roller 18 driving the material. The second electrode 21 passes through the second through hole 20 and is located at the center of the inner wall of the second through hole 20. The outer wall of the second electrode 21 is in contact with the inner wall of the second through hole 20. The second isolation sleeve 19, in conjunction with the second through hole 20, can help the material adhere to the outer wall of the second isolation sleeve 19 and does not directly contact the second electrode 21.

[0029] Please see Figures 3-7 In this embodiment, the first support plate 4 and the second support plate 5 are symmetrically distributed front and back, the two sets of first rollers 12 are centrally symmetrically distributed, the bearing plate 16 is installed at an angle, and the electrostatic sensor 17 is located on the side below the first roller 12. The inclined bearing plate 16 can set the electrostatic sensor 17 at an angle on the side below the two sets of first rollers 12 for detection. The front end of the electrical isolation cover 1 has a first notch 22, and the right end of the electrical isolation cover 1 has a second notch 23. The first notch 22 is adapted to the cabinet door 10, and the second notch 23 corresponds to the position of the two sets of first rollers 12. The electrical isolation cover 1 can isolate and protect the high voltage electric field generated by the first electrode 15, the second electrode 21, and the electrostatic sensor 17 to avoid injury to the operator.

[0030] The electrostatic sensor 17 can be of the ESD-2005 / 2002 series, NEOS12 / X-33 series, or HD-BM100 series. The specific control method of this utility model is as follows:

[0031] 1. Material input and pretreatment

[0032] In the roll-changing process of continuous BOPET film production, when a new roll core is ready to receive the film, the material enters the device through the second opening 23 of the electrical isolation cover 1. The film will pass through two sets of centrally symmetrically distributed first rollers 12 in sequence. At this time, the first electrode 15 on the outer wall of the first roller 12 applies an initial electrostatic field uniformly to the upper and lower surfaces of the film through the first through hole 14 of the first isolation sleeve 13. This electrostatic field is provided by the electrostatic generator 9, which lays the foundation for the subsequent film adsorption on the new roll core.

[0033] 2. Real-time monitoring of electrostatic data

[0034] After the film passes through the first roller 12, the electrostatic sensor 17 immediately detects the electrostatic state of its surface. Due to the material characteristics of BOPET film (specific conductivity and dielectric constant), it needs to be matched with a specific electrostatic strength to ensure flat adsorption. The detected electrostatic data will be transmitted to the CNC table 2 in real time as a key basis for control.

[0035] 3. Feedback-regulated electrostatic generator 9

[0036] The CNC stage 2 compares the detected electrostatic data with the system's built-in "BOPET film roll change adaptation electrostatic strength threshold". If the detected value is lower than the adaptation threshold, it will result in insufficient film adhesion and failure to tightly adhere to the new roll core. At this time, the CNC stage 2 sends an "enhance output" command to the electrostatic generator 9. If the detected value is higher than the adaptation threshold, it may cause local damage to the film or excessive adhesion and wrinkles. In this case, the CNC stage 2 sends a "reduce output" command.

[0037] 4. Electrostatic field after electrode output adjustment

[0038] The electrostatic generator 9 adjusts the output current intensity according to the instructions of the CNC console 2. The first electrode 15 and the second electrode 21 change the electrostatic field intensity applied to the film pretreatment stage and the winding stage, respectively. The first electrode 15 ensures that the electrostatic field on the film surface is uniform and meets the requirements of BOPET material when changing rolls, thus improving the adsorption base. The second electrode 21 adjusts the electrostatic field synchronously to ensure that the adsorption force is stable when the film is wound into the new roll core under the guidance of the second roller 18, avoiding slippage or wrinkles caused by improper electrostatic field, and ensuring a smooth roll changing process.

[0039] 5. Continuous optimization of closed loop

[0040] During the roll change process, as the film is continuously conveyed, the electrostatic sensor 17 continuously detects and feeds back data, and the CNC console 2 continuously adjusts the electrostatic generator 9 to form a dynamic closed-loop control, ensuring that the BOPET film is always in the optimal electrostatic adsorption state throughout the entire roll change process, so as to successfully complete the roll change. After the roll change is completed, the device stops working and does not participate in the normal winding process.

[0041] During use, the electrical isolation cover 1 can continuously shield the high-voltage electrostatic field generated by the first electrode 15 and the second electrode 21, minimizing the interference and damage to operators or surrounding equipment caused by electric field leakage. At the same time, during the operation of the electrostatic generator 9, the alarm light 7 will remain constantly lit to indicate that "the equipment is in a high-voltage working state". Operators must keep a safe distance of more than 1 meter from the equipment and are prohibited from touching the electrical isolation cover 1 and the cabinet door 10. The first isolation sleeve 13 of the first roller 12 and the second isolation sleeve 19 of the second roller 18, which are made of rubber, can prevent materials from directly contacting the first electrode 15 and the second electrode 21, and also prevent electric shock when operators accidentally touch the electrodes.

[0042] Through the above steps, by using the electrostatic generator 9, the first electrode 15 and the second electrode 21 in conjunction with the first roller 12 and the second roller 18, an electrostatic field can be uniformly applied to both the upper and lower surfaces of the material. At the same time, the electrostatic field can also be applied to the second roller 18 to perform efficient and stable automatic roll changing on the end of the material to which the electrostatic field has been applied. The electrostatic sensor 17 can detect the electrostatic data of the electrostatic field on the material in real time, so as to adjust the intensity of the electrostatic field generated by the electrostatic generator 9 according to the different materials. This solves the problem that existing BOPET winding electrostatic adsorption devices are difficult to perform efficient and stable automatic roll changing on materials of different materials.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
