Description

Technical Field

[0001] This utility model relates to the field of support and tensioning structure technology, and in particular to a support and tensioning structure for the production of glass fiber mesh. Background Technology

[0002] Fiberglass mesh is a unique material made of interwoven fiberglass yarns. It possesses extremely strong tensile, impact, and bending resistance, and is as tough as steel, effectively withstanding various external impacts. It also has excellent corrosion resistance, resisting the erosion of various chemicals such as acids, alkalis, and salts, and maintaining its original performance and appearance for a long time. Fiberglass mesh is widely used in many fields such as construction, shipbuilding, vehicles, electronics, and aerospace.

[0003] In the production process of fiberglass mesh, multiple rollers are usually deployed to support and guide the mesh. The tension of the slack mesh can be adjusted by adjusting the position of the rollers. However, the adjusted rollers are difficult to adapt to changes in the state of the mesh. Once the mesh becomes slack or too tight again, the workers cannot detect it in time. This not only reduces the support effect of the rollers on the mesh, but also causes problems such as jamming and wrinkling of the mesh during the conveying process. Therefore, a support and tensioning structure for fiberglass mesh production is proposed. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems existing in the current support and tensioning structure for the production of glass fiber mesh, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a support and tensioning structure for the production of glass fiber mesh, which is suitable for solving the problem that the adjusted roller is difficult to adaptively adjust to the changes in the state of the glass fiber mesh. Once the mesh becomes loose or too tight again, it will not only easily cause the support effect of the roller on the mesh to decrease, but also cause the mesh to jam and wrinkle during the conveying process.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a support and tensioning structure for the production of glass fiber mesh, comprising:

[0008] The support unit includes a support platform and two support plates fixedly connected to the top of the support platform. Two pairs of conveying rollers are rotatably connected between the two support plates.

[0013] As a preferred embodiment of the support and tensioning structure for producing glass fiber mesh fabric according to this utility model, the top of the support platform is provided with two symmetrically distributed movable plates, and the top of each of the two movable plates is rotatably connected to a limit rod. One side of one of the support plates is rotatably connected to a rotating rod, one end of which passes through the support plate and is fixedly connected to a positive and negative threaded rod. The two movable plates are respectively threaded onto the two ends of the positive and negative threaded rod.

[0014] As a preferred embodiment of the support and tensioning structure for the production of glass fiber mesh fabric described in this utility model, the two support plates are rotatably connected by multiple support rods, and the multiple support rods are all close to the bottom of the support plates and are distributed at equal intervals.

[0015] The beneficial effects of this utility model are as follows: The electric telescopic rod drives the adjusting roller to descend, thereby pulling the glass fiber mesh cloth and tightening it.

[0026] Example

[0027] Reference Figures 1-3 As an embodiment of the present invention, a support and tensioning structure for the production of glass fiber mesh is provided, comprising: a support unit 100 and a tensioning unit 200;

[0028] The support unit 100 includes a support platform 101 and two support plates 102 fixedly connected to the top of the support platform 101. Two pairs of conveying rollers 103 are rotatably connected between the two support plates 102.

[0029] The tensioning unit 200 includes a fixed frame 201 fixedly connected to the top of two support plates 102. An electric telescopic rod 202 is fixedly installed at the bottom of the fixed frame 201. A gate-shaped plate 203 is fixedly connected to the output end of the electric telescopic rod 202. An adjusting roller 204 is rotatably connected to the inner wall of the gate-shaped plate 203. A rectangular opening 205 is opened on one side of one of the support plates 102. A lifting plate 206 is slidably installed in the rectangular opening 205. A threaded rod 207 is rotatably connected to the bottom of the rectangular opening 205 and passes through the lifting plate 206. The threaded rod 207 is threadedly connected to the lifting plate 206. Two T-shaped rods 208 slide through the top of the lifting plate 206. Springs 209 are sleeved on the rod surfaces of the two T-shaped rods 208. A pressure plate 210 is fixedly connected to the top of the two T-shaped rods 208. A pressure sensor 211 is fixedly installed on the top of the lifting plate 206.

[0030] First, one end of the fiberglass mesh is passed through the middle of a pair of conveying rollers 103. Then, the fiberglass mesh is moved to the bottom of the adjusting roller 204. Next, the fiberglass mesh is moved above the pressure plate 210. Then, the fiberglass mesh is passed through the middle of another pair of conveying rollers 103. The two pairs of conveying rollers 103 are used to support and convey the fiberglass mesh. By rotating the threaded rod 207, the lifting plate 206 can be raised and lowered along the rectangular opening 205. The spring 209 is used to push the pressure plate 210 upward so that it does not contact the pressure sensor 211. The adjusting roller 204 is driven to descend by the electric telescopic rod 202, so that the adjusting roller 204 presses the upper surface of the fiberglass mesh downward.

[0031] The tension of the fiberglass mesh can be adjusted using the adjusting roller 204, causing it to be in a V-shaped taut state. The taut fiberglass mesh then presses downward against the pressure plate 210, bringing it into contact with the pressure sensor 211. When the pressure sensor 211 senses a certain pressure, it controls the electric telescopic rod 202 to stop descending. When the fiberglass mesh relaxes again, the pressure sensed by the pressure sensor 211 decreases, and the electric telescopic rod 202 drives the adjusting roller 204 to descend. When the fiberglass mesh is too taut, the pressure sensed by the pressure sensor 211 increases, and the electric telescopic rod 202 drives the adjusting roller 204 to rise. The pressure sensor 211 is a device that can sense pressure signals and convert them into usable output electrical signals according to a certain rule. By presetting the pressure range sensed by the pressure sensor 211, the electric telescopic rod 202 can automatically adapt to the state of the fiberglass mesh according to the pressure value, thereby automatically adjusting the tension.

[0032] In addition, a connecting block 212 is fixedly connected to the top of the pressure plate 210, and rollers 213 are rotatably connected to both sides of the connecting block 212. A scale plate 214 is fixedly connected to one side of a support plate 102, and the lifting plate 206 is in contact with the scale plate 214.

[0033] The roller 213 contacts the fiberglass mesh, so that the moving fiberglass mesh drives the roller 213 to make contact, thereby reducing the wear of the pressure plate 210 on the fiberglass mesh. The height of the lifting plate 206 can be precisely adjusted by the scale plate 214 so that the taut fiberglass mesh can press down on the pressure plate 210 and keep the pressure of the pressure sensor 211 within a suitable range.

[0034] Specifically, two straight rods 215 are fixedly connected to the top of the door-shaped panel 203, and the upper ends of the two straight rods 215 slide through the fixing frame 201.

[0035] When the electric telescopic rod 202 drives the portal plate 203 to rise and fall, the straight rod 215 can improve the stability of the portal plate 203's rise and fall, so that the portal plate 203 will not deviate, thereby ensuring that the adjusting roller 204 and the conveying roller 103 remain in a horizontal state and ensuring the smooth conveying of the glass fiber mesh cloth.

[0036] Furthermore, two symmetrically distributed movable plates 216 are slidably arranged on the top of the support platform 101. The top of each movable plate 216 is rotatably connected to a limit rod 217. One side of one of the support plates 102 is rotatably connected to a rotating rod 218. One end of the rotating rod 218 passes through the support plate 102 and is fixedly connected to a positive and negative threaded rod 219. The two movable plates 216 are respectively threaded onto the two ends of the positive and negative threaded rod 219.

[0037] The positive and negative threaded rods 219 have two threads in opposite directions. The positive and negative threaded rods 219 are rotated by the rotating rod 218, which can make the two moving plates 216 move closer or further apart, so that the two limiting rods 217 can limit the two sides of the glass fiber mesh cloth, thereby ensuring that the glass fiber mesh cloth is always located at the center of the conveying rollers 103 when passing between the two conveying rollers 103.

[0038] Furthermore, multiple support rods 104 are rotatably connected between the two support plates 102, and the multiple support rods 104 are all close to the bottom of the support plate 102 and are distributed at equal intervals.

[0039] The lifting plate 206 and the support rod 104 do not contact each other. When the end of the fiberglass mesh cloth is removed from the pair of conveying rollers 103 near the limit rod 217, the fiberglass mesh cloth will fall onto the multiple support rods 104 and slide on the support rods 104 for conveying. This can prevent the end of the fiberglass mesh cloth from rubbing against the surface of the support table 101, thereby preventing wear of the fiberglass mesh cloth.

[0040] During use, firstly, one end of the fiberglass mesh is passed through the middle of the two pairs of conveying rollers 103, and the fiberglass mesh is positioned below the adjusting roller 204 and above the roller 213. Then, the rotating rod 218 is rotated to limit the two sides of the fiberglass mesh with its two limiting rods 217. Then, the threaded rod 207 is rotated and the height of the lifting plate 206 is adjusted through the scale plate 214. Subsequently, the electric telescopic rod 202 drives the adjusting roller 204 to descend, causing the adjusting roller 204 to press down on the upper surface of the fiberglass mesh, making the fiberglass mesh taut downwards. Then, the taut fiberglass mesh presses down on the roller 213, causing the pressure plate 210 to contact the pressure sensor 211.

[0041] When the pressure sensor 211 senses a certain pressure, the electric telescopic rod 202 stops descending. When the pressure sensed by the pressure sensor 211 decreases, the electric telescopic rod 202 drives the adjusting roller 204 to descend. When the fiberglass mesh is too taut, the pressure sensed by the pressure sensor 211 increases, and the electric telescopic rod 202 drives the adjusting roller 204 to rise. By preset the pressure range sensed by the pressure sensor 211, the electric telescopic rod 202 can automatically adapt to the state of the fiberglass mesh according to the pressure value, so as to automatically adjust the tension.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
