Abstract
Description
Technical Field
[0001] The present invention relates to the field of fiberglass cloth production, and particularly to a device for removing air bubbles after fiberglass cloth is impregnated with glue. Background Art
[0002] After the existing fiberglass cloth is impregnated with glue and dried, a semi-cured sheet is formed on its surface. Due to the warp and weft knitting method of the fiberglass cloth and the semi-fluidity of the glue, air is easily trapped in the gaps of the fiberglass cloth during impregnation to form air bubbles, resulting in uneven impregnation of the semi-cured sheet. When the impregnated glue solidifies, it will cause the surface of the semi-cured sheet to be uneven, generating semi-cured sheets with unqualified appearance and affecting the production quality of the semi-cured sheets.
[0003] Therefore, there is a device for removing air bubbles after fiberglass cloth is impregnated with glue with the patent number CN220461193U. While solving the above problems, this device also has the following defects. For example, it only pulls the fiberglass cloth through between two sets of extrusion rollers by an external traction device, and then plays a role in squeezing and removing air bubbles on its surface. However, it is very difficult to ensure that the fiberglass cloth is not in a slack state. When the slack fiberglass cloth slides through between two sets of extrusion rollers with a fixed distance, on the one hand, it is easy to get stuck due to its wrinkles, and on the other hand, it is not easy to evenly squeeze and remove air bubbles on its surface. Summary of the Invention
[0004] The purpose of the present invention is to provide a device for removing air bubbles after fiberglass cloth is impregnated with glue.
[0005] The technical problems of the present invention are mainly solved by the following technical solutions:
[0006] A device for removing air bubbles after fiberglass cloth is impregnated with glue, comprising a box body:
[0007] Vertical plates are arranged on both sides of the top of the box body. A driving roller driven by a motor I is arranged between the two sets of vertical plates. A transmission roller is arranged in the box body directly below the driving roller. A tensioning mechanism is arranged in the box body between the transmission roller and the driving roller. Pressure mechanisms are arranged on both sides of the driving roller. The pressure mechanism includes a U-shaped plate with an upward opening. The U-shaped plate is inclined, and its bottom end is fixed on the side wall of the box body through a rotating shaft. A clamping roller that presses against one side of the driving roller is arranged at the opening of the U-shaped plate. A scraping plate I that is tangent to the bottom end surface of the clamping roller is arranged in the opening of the U-shaped plate. A N-pole magnetic seat arranged on the same side as the driving roller is arranged at the bottom of one side of the U-shaped plate. An arc-shaped notch is arranged at one end of the N-pole magnetic seat. A round rod driven by a motor II is arranged in the arc-shaped notch. The round rod is composed of a semi-circular N-pole magnetic rod and an S-pole magnetic rod;
[0008] The tensioning mechanism includes two sets of longitudinally arranged round shafts. The ends corresponding to the two sets of round shafts are connected by a connecting plate, and a motor III connected to the connecting plate is arranged outside the box body.
[0009] Preferably, a longitudinal plate is arranged in the box body on one side of the bottom of the C-shaped plate. The longitudinal plate and the N-pole magnetic seat are located on both sides of the C-shaped plate, and the longitudinal plate is connected to the C-shaped plate through a spring.
[0010] Preferably, a scraper II tangent to the bottom of the driving roller is arranged in the box body.
[0011] Preferably, a sleeve is sleeved on the round shaft.
[0012] Preferably, an overflow pipe is arranged on the side wall of the box body below the tensioning mechanism.
[0013] The beneficial effects of the present invention are as follows: When the external traction mechanism pulls the fiberglass cloth to move, the fiberglass cloth completes the dipping work in the box body. At this time, in order to improve the tightness of the fiberglass cloth to facilitate the extrusion and defoaming work of the clamping roller and the driving roller on it, the motor III can be used to drive the connecting plate to drive the two sets of round shafts to rotate, thereby twisting the fiberglass cloth to improve its tightness. When the fiberglass cloth passes between the driving roller and the clamping roller, the motor I drives the driving roller to rotate counterclockwise. The rotating driving roller drives the fiberglass cloth to smoothly slide into the box body for dipping work through the left clamping roller. At the same time, the rotating driving roller drives the fiberglass cloth to slide out of the box body through the right clamping roller and performs extrusion and defoaming work on it, so that the rotating driving roller can facilitate the fiberglass cloth to slide into or out of the box body through the two clamping rollers, and secondly, the air between the fiberglass cloths is squeezed out, thus avoiding the unqualified quality of the generated semi-cured sheet. At the same time, when the tensioning mechanism adjusts the tightness of the fiberglass cloth, the fiberglass cloth slides over the round shaft. At this time, the round shaft can perform preliminary extrusion and defoaming work on the surface of the fiberglass cloth to improve its processing effect; when the thickness of the fiberglass cloth is large, the clamping roller can be squeezed to drive the C-shaped plate to rotate slightly around the rotating shaft, so that a small distance is separated between the S-pole magnetic rod and the side wall of the N-pole magnetic seat. However, under the influence of the suction force between the two, it can still drive the clamping roller through the C-shaped plate to press the fiberglass cloth against the driving roller, so that it can adapt to the processing requirements of products with different thicknesses.

[0017] The following is a further specific description of the technical solution of the present invention through examples and in conjunction with the attached Figure 1-2 , drawings.
[0018] A device for removing air bubbles after fiberglass cloth is impregnated with glue, including a box body 1:
[0019] On both sides of the top of the box body 1, there are vertical plates 2. Between two groups of vertical plates 2, there is a driving roller 4 driven by a motor I 3. Inside the box body 1 directly below the driving roller 4, there is a driving roller 5. At the same time, inside the box body 1, there is a scraper II 10 tangent to the bottom of the driving roller 4. Inside the box body 1 between the driving roller 5 and the driving roller 4, there is a tensioning mechanism 6. On both sides of the driving roller 4, there are also pressing mechanisms 7;
[0020] The pressing mechanism 7 includes a C-shaped plate 71 with an upward opening. The C-shaped plate 71 is inclined, and its bottom end is fixed on the side wall of the box body 1 through a rotating shaft. At the opening of the C-shaped plate 71, there is a clamping roller 72 pressing against one side of the driving roller 4. Inside the opening of the C-shaped plate 71, there is also a scraper I 73 tangent to the bottom end surface of the clamping roller 72. At the bottom of one side of the C-shaped plate 71, there is an N-pole magnetic seat 74 arranged on the same side as the driving roller 4. One end of the N-pole magnetic seat 74 is provided with an arc-shaped notch 75. Inside the arc-shaped notch 75, there is a round rod 76 driven by a motor II 77. The round rod 76 is composed of a semi-circular N-pole magnetic rod 761 and an S-pole magnetic rod 762;
[0021] The tensioning mechanism 6 includes two longitudinally arranged round shafts 61. A sleeve is sleeved on the round shafts 61. At the same time, the corresponding ends between the two round shafts 61 are connected through a connecting plate 62. Outside the box body 1, there is a motor III 63 connected to the connecting plate 62.
[0022] As Figure 2 shown, inside the box body 1 on one side of the bottom of the C-shaped plate 71, there is a longitudinal plate 8. The longitudinal plate 8 and the N-pole magnetic seat 74 are located on both sides of the C-shaped plate 71. The longitudinal plate 8 is connected to the C-shaped plate 71 through a spring 9.
[0023] In this embodiment, an overflow pipe is arranged on the side wall of the box body 1 below the tensioning mechanism 6.
[0024] Usage method of the present invention: When installing the fiberglass cloth, the motor II 77 drives the round rod 76 to rotate in the arc-shaped notch 75, so that the N-pole magnetic rod 761 corresponds to the arc-shaped notch 75 in the N-pole magnetic seat 74. Then, under the influence of the same-sex repulsion, the N-pole magnetic seat 74 will drive the C-shaped plate 71 and the clamping roller 72 to rotate around the rotating shaft, expanding the distance between the clamping roller 72 and the driving roller 4, thereby facilitating the fiberglass cloth to pass through between the driving roller 4 and the clamping roller 72. At the same time, the fiberglass cloth passes through the opening formed between the connecting plate 62 and the two round shafts 61. Finally, the motor II 77 drives the round rod 76 to rotate in the arc-shaped notch 75, so that the S-pole magnetic rod 762 corresponds to the arc-shaped notch 75 in the N-pole magnetic seat 74. Then, under the influence of the opposite-sex attraction and the spring 9 stretching and pushing the C-shaped plate 71 to rotate, the arc-shaped notch 75 in the N-pole magnetic seat 74 can be effectively buckled on the S-pole magnetic rod 762 to make the two magnetically connected and fixed, thereby pressing the fiberglass cloth tightly between the clamping roller 72 and the driving roller 4, as specifically shown in Figure 2 shown;
[0025] When the external traction mechanism pulls the fiberglass cloth to move, the fiberglass cloth completes the dipping work in the box body 1. At this time, in order to improve the tightness of the fiberglass cloth to facilitate the clamping roller 72 and the driving roller 4 to perform the extrusion and defoaming work on it, the motor III 63 can be used to drive the connecting plate 62 to drive the two round shafts 61 to rotate, thereby twisting the fiberglass cloth to make it complete to improve its tightness. When the fiberglass cloth passes between the driving roller 4 and the clamping roller 72, the motor I 3 drives the driving roller 4 to rotate counterclockwise. The rotating driving roller 4 drives the fiberglass cloth to smoothly slide into the box body 1 for dipping work through the left clamping roller 72. At the same time, the rotating driving roller 4 drives the fiberglass cloth to slide out of the box body 1 through the right clamping roller 72 while performing the extrusion and defoaming work on it, so that the rotating driving roller 4 can, through the two clamping rollers 72, on the one hand, facilitate the fiberglass cloth to slide into or out of the box body 1, and on the other hand, also squeeze out the air between the fiberglass cloths, thereby avoiding the unqualified quality of the generated semi-cured sheet. At the same time, when the tensioning mechanism 6 adjusts the tightness of the fiberglass cloth, the fiberglass cloth slides over the round shaft 61. At this time, the round shaft 61 can perform the preliminary extrusion and defoaming work on the surface of the fiberglass cloth to improve its processing effect;
[0026] When the thickness of the fiberglass cloth is large, the clamping roller 72 can be squeezed to drive the C-shaped plate 71 to rotate slightly around the rotating shaft, thereby causing a small distance separation between the S-pole magnetic rod 762 and the side wall of the N-pole magnetic seat 74. However, under the influence of the suction force between the two, it can still drive the clamping roller 72 through the C-shaped plate 71 to press the fiberglass cloth against the driving roller 4, so that it can adapt to the processing requirements of products with different thicknesses.
[0027] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
