Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0025] Please see Figures 1-3 As shown, this embodiment discloses a mica tape processing and pressing structure, including a pressing structure and an auxiliary adhesive application device; the pressing structure is used to apply adhesive to the mica tape body and then press it together; the auxiliary adhesive application device is installed on the pressing structure;

[0026] The auxiliary adhesive application device includes a bracket 101, a roller 102, and a buffer assembly. The bracket 101 is mounted on the pressing structure, and the roller 102 is slidably mounted on the bracket 101 via a connecting rod 103. The roller 102 is rotatably connected to the connecting rod 103 and is used to compress the glass cloth 104. One end of the buffer assembly is mounted on the bracket 101, and the other end is connected to the connecting rod 103. The buffer assembly is used to buffer the roller 102.

[0027] This utility model mainly includes a pressing structure and an auxiliary glue application device. In actual use, the operator installs the mica paper 115 and the glass cloth 104 on the pressing structure for pressing. During this process, glue needs to be applied to the lower glass cloth 104. To prevent glue from dripping onto the glass cloth 104 and causing the glue at the edges of the mica paper 115 and glass cloth 104 to be squeezed out during pressing, the roller 102 is installed on the bracket 101 and makes the roller 102 contact with the lower glass cloth 104. After the roller 102 contacts the lower glass cloth 104, the glass cloth 104 is squeezed by the roller 102. After the glass cloth 104 is squeezed, the glue around it gathers towards the roller 102. During the continuous winding of the mica tape body, the glue can be effectively prevented from being located around the mica tape body, thereby preventing the glue from overflowing.

[0028] In some embodiments, the buffer assembly includes a push rod 105 and a spring 106. A sliding hole 107 is provided on the bracket 101. The spring 106 is installed inside the sliding hole 107. The push rod 105 is slidably installed inside the sliding hole 107 and connected to the end of the spring 106. One end of the spring 106 is fixedly connected to the bottom of the sliding hole 107, and the other end is fixedly connected to the push rod 105. The end of the push rod 105 is also fixedly connected to the connecting rod 103.

[0029] In actual use, the buffer assembly can effectively prevent hard contact between the roller 102 and the mica tape body. When the mica tape body is squeezed, the reaction force of the mica tape body acts on the roller 102, causing the roller 102 to be squeezed. After the roller 102 is squeezed, it pushes the slide rod to slide inside the slide hole 107 and squeezes the spring 106. The reaction force of the spring 106 acts on the mica tape body, so that the mica tape body and the roller 102 are balanced, thereby achieving buffering between the roller 102 and the mica tape body.

[0030] In some embodiments, the pressing structure is used to be disposed on the mounting platform 108.

[0031] In some embodiments, the pressing structure includes a feeding roller 109, a receiving roller 110, a first pressure roller 111, and a second pressure roller 112. The feeding roller 109 and the receiving roller 110 are rotatably mounted on the mounting platform 108 via a support frame 113. The first pressure roller 111 and the second pressure roller 112 are both mounted on the mounting platform 108 via a fixing frame 114. The receiving roller 110 is rotatably mounted on the support frame 113 via a first drive assembly. The first pressure roller 111 and the second pressure roller 112 are rotatably mounted on the fixing frame 114. The fixing frame 114 is provided with a second drive assembly. The first drive assembly and the second drive assembly are used to drive the take-up roller 110, the first pressure roller 111 and the second pressure roller 112 to rotate synchronously in opposite directions. The first drive assembly and the second drive assembly are used to drive the take-up roller 110, the first pressure roller 111 and the second pressure roller 112 to rotate synchronously at the same speed. There are two feed rollers 109, and both feed rollers 109 are rotatably mounted on the fixed frame 114. The two feed rollers 109 are used to take up mica paper 115 and glass cloth 104 respectively. After passing between the first pressure roller 111 and the second pressure roller 112, the mica paper 115 and the glass cloth 104 are fixedly connected to the take-up roller 110 and are used to be wound on the take-up roller 110.

[0032] In actual use, when pressing the mica tape body, the mica paper 115 and glass cloth 104 are first wound onto two feeding rollers 109, with the glass cloth 104 below and the mica paper 115 above. Then, the glass cloth 104 and mica paper 115 are pulled, and the ends of the mica paper 115 and glass cloth 104 are fixed using long iron clamps. Then, glue is applied to the glass cloth 104, and the fixed mica paper 115 and glass cloth 104 are manually pulled through the first pressure roller 111 and the second pressure roller 112. The outer part of the winding roller is then... A magnet is embedded in the wall. When the long iron clip comes into contact with the magnet, it is fixed. Then, the first drive component starts the take-up roller 110 to rotate. At the same time, the second drive component drives the first pressure roller 111 and the second pressure roller 112 to rotate synchronously. When the glass cloth 104 and mica paper 115 on the feed roller 109 pass through the first pressure roller 111 and the second pressure roller 112, the glass cloth 104 and the glass paper squeeze the glue, so that the glue is evenly coated between the glass cloth 104 and the mica paper 115, finally forming the mica tape body, which is then wound onto the take-up roller 110.

[0033] In some embodiments, the first drive assembly includes a first motor 116, the fixed end of the first motor 116 is disposed on the support frame 113, and the output shaft of the first motor 116 passes through the support frame 113 and is fixedly connected to the receiving roller 110.

[0034] In actual use, the output shaft of the first motor 116 rotates, driving the receiving roller 110 to rotate, thereby realizing the rotation of the receiving roller 110.

[0035] In some embodiments, the second drive structure includes a second motor 117 and a transmission mechanism. The fixed end of the second motor 117 is disposed on the fixed frame 114. The output shaft of the second motor 117 is rotatably connected to the fixed frame 114 and fixedly connected to the end of the second pressure roller 112. The transmission mechanism is disposed on the fixed frame 114 and the first pressure roller 111. The second motor 117 controls the rotation of the first pressure roller 111 and the second pressure roller 112 through the transmission mechanism.

[0036] In actual use, after the second motor 117 rotates, it controls the first pressure roller 111 and the second pressure roller 112 to rotate in opposite directions through the transmission mechanism. At this time, the first pressure roller 111 and the second pressure roller 112 rotate in opposite directions, thereby realizing the transmission of the extruded mica belt body.

[0037] In some embodiments, the transmission mechanism includes a driving pulley 118, a driven pulley 119, a rotating shaft 120, a first gear 121, and a second gear 122. The rotating shaft 120 is rotatably mounted on a fixed plate. The driven pulley 119 and the first gear 121 are fixedly mounted on the rotating shaft 120. The driving pulley 118 is fixedly mounted on the end of the second pressure roller 112. The second gear 122 is fixedly mounted on the end of the first pressure roller 111. The first gear 121 and the second gear 122 mesh with each other. A transmission belt 123 is sleeved on the driving pulley 118 and the driven pulley 119.

[0038] In actual use, the second motor 117 rotates, driving the drive pulley 118 to rotate. The drive pulley 118 rotates, driving the rotating shaft 120 to rotate. The rotating shaft 120 rotates, driving the first gear 121 to rotate. Since the second gear 122 meshes with the first gear 121, the rotation of the first gear 121 drives the second gear 122 to rotate. When the drive pulley 117 and the second gear 122 rotate, the first pressure roller 111 and the second pressure roller 112 rotate.

[0039] In some embodiments, the support frame 113 is further provided with an adhesive applicator for applying adhesive to the glass cloth 104 located below, and the bracket 101 is disposed on the adhesive applicator.

[0040] In actual use, the purpose of setting up the glue application device is to facilitate the application of glue to the glass cloth 104.

[0041] In some embodiments, the glue application device includes a glue storage tank 124, a temporary storage box 125, and glue dispensing heads 126. The glue storage tank 124 is disposed below the mounting platform 108. The glue storage tank 124 is connected to the temporary storage box 125 through a booster pump 127 and a pipeline 128. The temporary storage box 125 is mounted on a support frame 113. There are several glue dispensing heads 126, which are installed below the temporary storage box 125 and communicate with the interior of the temporary storage box 125.

[0042] In actual use, the booster pump 127 draws out the glue from the glue storage tank 124 and passes the glue into the temporary storage box 125. The glue is then discharged through the glue outlet. After the glue drips onto the glass cloth 104, it is pressed together with the mica paper 115 to form the mica tape body.
