Description

Technical Field

[0001] This utility model relates to the field of mica tape production technology, specifically a mica tape composite molding device. Background Technology

[0002] Mica tape is made primarily of mica paper, which is produced by frying synthetic mica, and then adhesive is used to bond glass cloth to one or both sides. Tape with glass cloth bonded to one side of the mica paper is called "single-sided tape," while tape with glass cloth bonded to both sides is called "double-sided tape." During manufacturing, several structural layers are bonded together, then dried in an oven, rolled up, and finally cut into tapes of different specifications.

[0003] A search revealed publication number (CN214605985U) discloses a composite equipment for producing mica tape, comprising a housing horizontally placed on the ground with multiple heat dissipation holes; a transmission device disposed within the housing for applying rotational force to mica paper and film; a pressing mechanism disposed above the housing for laminating the mica paper and film; and a guiding mechanism disposed on the housing for guiding the laminated mica paper and film to the next device. Further, the transmission device includes a first transmission shaft laterally inserted into the housing, and a second transmission shaft laterally inserted into the housing to the right of the first transmission shaft.

[0004] The technical solution has at least the following drawbacks: while it can guide and flatten mica paper and film, it cannot adjust the tension of the mica paper and film, leading to wrinkles in the flattened mica paper and film. Therefore, we propose a mica tape composite forming device. Utility Model Content

[0005] The purpose of this invention is to provide a mica tape composite forming device, which solves the problem mentioned in the background art that the tension of the mica paper and film cannot be adjusted, resulting in wrinkles in the composite flattened mica paper and film.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mica tape composite molding device, comprising a molding frame, with a first hydraulic cylinder fixedly installed at both the front and rear ends of one side of the molding frame, a lower pressure roller provided in the inner cavity of one side of the molding frame, a connecting frame welded to both ends of the lower pressure roller and slidably connected to the molding frame, guide rollers rotatably installed at both ends of the other side of the molding frame, a tensioning roller provided in the middle of the molding frame, a tensioning frame rotatably connected to one side of the tensioning roller, a second hydraulic cylinder fixedly installed at both the front and rear ends of the other side of the molding frame, a wedge block installed at the output end of the second hydraulic cylinder, a fixed plate slidably installed on one side of the tensioning frame, and a smooth rod welded to the upper end of the fixed plate.

[0007] By adopting the above technical solution, the reaction force of the wedge block can push the fixed plate, which in turn pushes the tensioning frame through the pressure sensor. This causes the tensioning frame to move along with the tensioning roller, thereby adjusting the tension of the mica paper and film. This reduces the occurrence of pressure wrinkles in the laminated mica paper and film. At the same time, the reaction force pushes the fixed plate to squeeze the pressure sensor, which then transmits the pushing force to the tensioning frame. The pressure sensor detects the tension of the tensioning frame, and when it detects that the pressure has reached a threshold, it transmits a signal to the PLC controller. The PLC controller then controls the second hydraulic cylinder to close, thus preventing the tensioning frame from moving excessively and improving the lamination effect of the mica tape.

[0008] Optionally, the smooth rod is disposed on one side of the wedge block, and the smooth rod is in contact with the inclined surface of the wedge block.

[0009] By adopting the above technical solution and setting the smooth rod, the smoothness of the contact between the fixed plate and the wedge block can be guaranteed.

[0010] Optionally, a pressure sensor is fixedly installed in the middle of the inner side of the tensioning frame, and the other side of the pressure sensor is attached to the fixing plate.

[0011] By adopting the above technical solution and setting up a pressure sensor, the tension force can be monitored, thus avoiding excessive movement of the tensioning frame.

[0012] Optionally, the tensioning frame is located in the middle of the forming frame, and the tensioning frame is slidably connected to the forming frame.

[0013] By adopting the above technical solution, it is easy to ensure the stability of the tensioning frame movement.

[0014] Optionally, a transmission roller is rotatably mounted on the lower end of one side of the forming frame, and the rear end of the transmission roller is fixedly connected to the output shaft of the transmission motor.

[0015] By adopting the above technical solution and setting the transmission rollers, the passing mica paper and film can be composite flattened and formed.

[0016] Optionally, the connecting frame of the pressure roller at the output end of the first hydraulic cylinder can be detachably connected.

[0017] By adopting the above technical solution and by setting up the first hydraulic cylinder, the lower pressure roller can be driven to move up and down.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application, through the setting of a forming frame, a first hydraulic cylinder, a guide roller, a tensioning frame, a tensioning roller, a second hydraulic cylinder, a wedge block, and a fixed plate, allows the wedge block's reaction force to push the fixed plate. The fixed plate, through a pressure sensor, pushes the tensioning frame, which in turn causes the tensioning roller to move accordingly. This achieves the effect of adjusting the tension of the mica paper and film, thereby reducing the occurrence of pressure wrinkles in the laminated and flattened mica paper and film. At the same time, the reaction force pushes the fixed plate to squeeze the pressure sensor, causing the pressure sensor to transmit the pushing force to the tensioning frame. This allows the pressure sensor to detect the tension of the tensioning frame. When the pressure sensor detects that the pressure has reached a threshold, it transmits a signal to the PLC controller. The PLC controller then controls the second hydraulic cylinder to close, thus preventing the tensioning frame from moving excessively and improving the lamination effect of the mica tape.

[0025] Please see Figure 1-3This utility model provides a technical solution: a mica tape composite molding device, including a molding frame 1, with first hydraulic cylinders 11 fixedly installed at both ends of one side of the molding frame 1, a lower pressure roller 12 provided in the inner cavity of one side of the molding frame 1, and connecting frames welded to both ends of the lower pressure roller 12 slidably connected to the molding frame 1, guide rollers 14 rotatably installed at both ends of the other side of the molding frame 1, a tensioning roller 21 provided in the middle of the molding frame 1, a tensioning frame 26 rotatably connected to one side of the tensioning roller 21, and second hydraulic cylinders 22 fixedly installed at both ends of the other side of the molding frame 1, with wedge blocks 23 installed at the output end of the second hydraulic cylinder 22, and the tensioning frame 26... A fixed plate 2 is slidably installed on one side, and a smooth rod 24 is welded to the upper end of the fixed plate 2. The tensioning frame 26 is set in the middle of the forming frame 1 and is slidably connected to the forming frame 1 to ensure the stability of the movement of the tensioning frame 26. A transmission roller 13 is rotatably installed on the lower end of one side of the forming frame 1. The rear end of the transmission roller 13 is fixedly connected to the output shaft of the transmission motor. Through the setting of the transmission roller 13, the passing mica paper and film can be composite flattened and formed. The connecting frame of the lower pressure roller 12 at the output end of the first hydraulic cylinder 11 is detachably connected. Through the setting of the first hydraulic cylinder 11, the lower pressure roller 12 can be driven to move up and down.

[0026] The smooth rod 24 is set on one side of the wedge block 23 and is in contact with the inclined surface of the wedge block 23. The smooth rod 24 ensures the smoothness of the contact between the fixing plate 2 and the wedge block 23.

[0027] A pressure sensor 25 is fixedly installed on the inner middle of the tensioning frame 26. The other side of the pressure sensor 25 is in contact with the fixing plate 2. By setting the pressure sensor 25, the tension force can be monitored, thus avoiding the tensioning frame 26 from moving excessively.

[0028] During adjustment, the second hydraulic cylinder 22 is first opened, causing the wedge block 23 to move downwards. The inclined surface of the wedge block 23 contacts the smooth rod 24, causing the reaction force of the wedge block 23 to push the fixed plate 2. The fixed plate 2, through the pressure sensor 25, pushes the tensioning frame 26, which in turn causes the tensioning frame 26 to drive the tensioning roller 21 to move accordingly. This achieves the effect of adjusting the tension of the mica paper and film, thereby reducing the occurrence of pressure wrinkles in the laminated and flattened mica paper and film. At the same time, the reaction force pushes the fixed plate 2 to squeeze the pressure sensor 25, causing the pressure sensor 25 to... 5. The pushing force is transmitted to the tensioning frame 26, so that the pressure sensor 25 detects the tension of the tensioning frame 26. When the pressure sensor 25 detects that the pressure reaches the threshold, the pressure sensor 25 will transmit the signal to the PLC controller. The PLC controller controls the second hydraulic cylinder 22 to close, thereby avoiding the tensioning frame 26 from moving excessively, thus improving the composite molding effect of the mica tape. Finally, the first hydraulic cylinder 11 is controlled to retract, so that the first hydraulic cylinder 11 drives the lower pressure roller 12 to move downward, so that the lower pressure roller 12 cooperates with the transmission roller 13 to composite and flatten the passing mica paper and film.
