Description

Technical Field

[0001] The invention relates to the field of glass fiber mesh cloth rolling, in particular to an automatic glass fiber mesh cloth rolling device. Background Art

[0002] Glass fiber mesh is a mesh fabric with glass fiber woven fabric as the base material and impregnated with a polymer anti-emulsion coating. It has good alkali resistance, flexibility, and high tensile strength in the warp and weft directions. It is widely used in the fields of thermal insulation, waterproofing, fire prevention, and crack resistance of internal and external walls of buildings. The production process of glass fiber mesh includes raw material preparation, weaving processing, coating processing, drying and curing, cutting and winding processing, among which, winding processing refers to installing the processed and qualified glass fiber mesh on a roll to form a curled state, which is convenient for the subsequent storage, transportation and use of the glass fiber mesh. The rolled glass fiber mesh can be cut in sections according to the required width to obtain the required product.

[0003] However, there are still the following problems in the process of rolling and cutting the glass fiber mesh: (1) The rolling and cutting processes are separate and carried out one after the other.

[0036] See also Figure 1 , Figure 2 and Figure 6 The cutting unit 11 includes a rotating shaft 111 symmetrically arranged at the upper end of the base 1, and a plurality of groups of evenly arranged rolling elements are sleeved on the upper and lower rotating shafts 111. The rolling elements are composed of left-right symmetrical rollers 112. A cutter 113 sleeved on the rotating shaft 111 is arranged between the left and right rollers 112 of the same group on the upper rotating shaft 111.

[0037] See also Figure 2 and Fig. 9The front and rear sides of the cutting unit 11 are symmetrically provided with a tensioning assembly for tightening the glass fiber mesh 3. The tensioning assembly includes a trapezoidal plate 121 which is symmetrical up and down and in a triangular shape as a whole. The ends of the upper and lower trapezoidal plates 121 that are close to each other are horizontal sections.

The other end of the spring telescopic rod 122 is fixedly connected to the vertical section of an inverted U-shaped frame 123. The inverted U-shaped frame 123 is symmetrically installed on the upper end of the base 1.

[0038] See also Figure 1 , Figure 2 and Figure 3 The driving assembly includes a driven pulley 131 rotatably connected to the left end face of the left vertical section of the gantry 2, a block 132 is installed on the left end of the rotating column 211, and a slot slidably connected to the block 132 is opened on the driven pulley 131. A driving pulley 133 is installed on the left end of the upper rotating shaft 111. The driving pulley 133 and the driven pulley 131 are connected by belt transmission. The left end face of the driving pulley 133 is connected to the output shaft of the motor 134. The motor 134 is installed on the upper end of the base 1 through a support. The left end of the rotating shaft 111 below is rotatably connected to the support, and the upper and lower rotating shafts 111 are fixedly sleeved with gears 135 located on the right side of the driving pulley 133 and meshing with each other.

[0039] Before rolling up the glass fiber mesh 3, the reel 215 can be put between the left and right rotating columns 211 onto the corresponding rotating column 211. During this process, the reel 215 gradually squeezes the top column 225. Under the action of the telescopic spring 226, the top column 225 gradually moves downward along the mounting hole 223 until the circular groove on the inner ring surface of the reel 215 moves to correspond to the top column 225. At this time, the top column 225 moves upward along the mounting hole 223 under the action of the telescopic spring 226 until it is engaged with the circular groove. In this way, the circumferential rotation of the reel 215 is limited. Similarly, the reels 215 are put onto the rotating column 211 one by one, and then the left and right rotating columns 211 are pushed toward each other synchronously by the two-way hydraulic adjustment telescopic rod 237 until the left and right rotating columns 211 collide with each other, and the protruding block 212 slides with the alignment groove to make the left and right rotating columns 211 form a whole. Then, the axial movement of the reel 215 can be limited by plugging the limiting rod 222 with the limiting hole 221.

[0040] In addition, before the subsequent reel 215 needs to reel up the glass fiber mesh 3 of different widths, a suitable reel 215 can be selected, and then the top column 225 can be rotated to thread the mounting column 224 out of the mounting hole 223 through the telescopic spring 226. Then, a suitable mounting hole 223 can be selected according to the size of the reel 215, and the mounting column 224, the telescopic spring 226 and the top column 225 can be threadedly installed as a whole in the corresponding mounting hole 223 to achieve circumferential limitation of multi-sized reels 215. In addition, the connection position of the limit rod 222 and the limit hole 221 can be selected according to the size of the reel 215 to achieve axial limitation of the multi-sized reel 215.

[0041] During the specific operation: first, the glass fiber mesh cloth 3 produced by the existing production device needs to be transported from front to back in the direction of the base 1 through the existing conveying device, and then the glass fiber mesh cloth 3 is passed through the trapezoidal plates 121 symmetrically arranged on the front side. During this process, the clamping plate 124 can be manually pushed to compress the connecting spring 125 and move in the direction of the corresponding trapezoidal plate 121, so that the glass fiber mesh cloth 3 can pass smoothly. At the same time, the glass fiber mesh cloth 3 is always in a backward conveying state, and the glass fiber mesh cloth 3 moves accordingly and gradually approaches the cutter 113. Then, the upper rotating shaft 111 can be driven to rotate by the motor 134, and the upper roller 112 and the cutter 113 rotate synchronously with the upper rotating shaft 111. Due to the meshing between the upper and lower gears 135, the lower rotating shaft 111 drives the lower The rollers 112 rotate synchronously in the opposite direction, and the cutter 113 located above the glass fiber mesh 3 rotates synchronously and rapidly with the rotating shaft 111, thereby realizing the cutting of the glass fiber mesh 3. The glass fiber mesh 3 cut by the cutter 113 is divided into multiple strips and continues to be transported backward through between the upper and lower rollers 112. While the cutter 113 cuts the glass fiber mesh 3, the rollers 112 on the upper and lower rotating shafts 111 rotate synchronously with the corresponding rotating shafts 111. The synchronously counter-rotating rollers 112 can assist in conveying the cut glass fiber mesh 3 to move backward. In addition, the upper and lower rollers 112 can also guide and suppress the glass fiber mesh 3 during the cutting process, which is beneficial for the cutter 113 to smoothly perform the cutting work. The cooperation of the upper and lower rollers 112 can not only achieve the assistance of cutting, but also achieve the assistance of feeding, thereby improving the efficiency of winding and cutting.

[0042] The cut glass fiber mesh 3 gradually passes through the upper and lower symmetrical trapezoidal plates 121 on the rear side. The two sets of trapezoidal plates 121 symmetrically arranged in front and back can support and smooth the glass fiber mesh 3 during the cutting and rolling process. In the process of the glass fiber mesh 3 passing through the two sets of trapezoidal plates 121, the upper and lower relative clamping plates 124 move toward each other under the action of the connecting spring 125 and clamp the glass fiber mesh 3. With the cooperation between the trapezoidal plates 121, the connecting spring 125 and the clamping plates 124, the glass fiber mesh 3 is always in a horizontally taut state. In addition, as the glass fiber mesh 3 is subsequently rolled up, the tilted state of the glass fiber mesh 3 is also Changes occur, at which time the trapezoidal plate 121 drives the connecting spring 125 and the clamping plate 124 and moves forward and backward under the action of the spring telescopic rod 122 to adapt to the required tension state of the glass fiber mesh cloth 3, not only preparing for the subsequent winding, but also making the glass fiber mesh cloth 3 automatically in a tensioned state before and after cutting, so that the cutting and winding of the glass fiber mesh cloth 3 share a tensioning component for tensioning, which greatly saves production costs. It should be noted that the glass fiber mesh cloth 3 that has just been wound up needs to be pulled at its end with the help of external force to ensure smooth transmission and cutting, and the glass fiber mesh cloth 3 does not need to be transported with the help of external force in the subsequent normal winding process.

[0043] The cut glass fiber mesh cloth 3 continues to move toward the direction where the reel 215 is located through the tensioning assembly. After the cut glass fiber mesh cloth 3 reaches the position where the reel 215 is located, it is necessary to first use external force to fix the ends of the cut glass fiber mesh cloth 3 on the corresponding reel 215 one by one. In the process of the hydraulic two-way push rod pushing the left and right rotating columns 211 to move synchronously toward each other, the rotating column 211 is engaged with the slot on the driven pulley 131 through the block 132. When the motor 134 drives the upper rotating shaft 111 to rotate, the active pulley 133 rotates synchronously therewith, and the driven pulley 131 rotates synchronously with the active pulley 133 through the cooperation of the belt. The active pulley 133 drives the left and right rotating columns 211 to rotate synchronously with the reel 215 as a whole through the cooperation of the block 132 and the slot. The single-axis rotation of the rotating shaft 111, the belt and the driven pulley 131 are realized through the cooperation between the active pulley 133, the belt and the driven pulley 131. A driving source drives the winding and cutting to be carried out synchronously, the rotating column 211 drives the reel 215 to rotate synchronously as a whole, and the cut glass fiber mesh cloth 3 is then wound around the corresponding reel 215 one by one, and the cut glass fiber mesh cloth 3 is separately wound up by the reel 215. After the glass fiber mesh cloth 3 is completely wound up, the driving component stops working, the rotating column 211 and the rotating shaft 111 stop rotating synchronously, and the cutter 113, the roller 112 and the reel 215 stop working synchronously. At this time, the reel 215 that has completed winding can be taken down from the rotating column 211; the glass fiber mesh cloth 3 is cut during the winding process, and the cutting and winding are integrated, which greatly improves the winding efficiency. There is no need to cut the rolled glass fiber mesh cloth 3 into different widths according to demand after the winding is completed. Compared with the traditional method of rolling first and then cutting, the operation and processing time is saved.

[0044] During this process, the control plate 213 can be pushed in the opposite direction synchronously by the bidirectional hydraulic push rod 214, and the control plate 213 drives the corresponding rotating column 211 to move in the opposite direction synchronously, and the protruding block 212 gradually disengages from the alignment groove. After the rotating columns 211 on the left and right sides move away from each other, the reel 215 can be removed from the rotating column 211 after the winding is completed by existing equipment or manually. In the process of the reel 215 disengaging from the rotating column 211, the semi-spherical section of the top column 225 is squeezed and the telescopic spring 226 is compressed, so that the top column 225 is away from the circular groove of the rotating column 211. At this time, the reel 215 can be smoothly separated from the rotating column 211, and then the reel 215 can be removed one by one and collected uniformly.

[0045] See also Figure 1 , Figure 2 , Figure 3 and Figure 5A pressure piece is provided at the lower end of the horizontal section of the gantry 2, and the pressure piece includes a rectangular plate 231 installed at the lower end of the horizontal section of the gantry 2, and a rectangular through groove 232 is provided on the rectangular plate 231. A spring telescopic rod 233 that is evenly arranged and corresponds to the reel 215 is slidably installed in the rectangular through groove 232, and a fixed block 234 is installed at the lower end of the telescopic section of the spring telescopic rod 233. Pressure rollers 235 are symmetrically provided at the left and right ends of the fixed block 234. A bidirectional threaded telescopic rod 236 installed at the lower end of the fixed block 234 is rotatably connected between the left and right pressure rollers 235 corresponding to the same fixed block 234, and a limiting groove is provided on the side where the left and right pressure rollers 235 are close to each other, and an adjusting telescopic rod 237 plugged into the limiting groove is symmetrically installed at the left and right ends of the fixed block 234.

[0046] In the process of the reel 215 rolling up the glass fiber mesh 3, the rolling parts at both ends of the reel 215 can be pressed by the pressure roller 235, which can not only ensure that the glass fiber mesh 3 is accurately wound on the reel 215, but also solidify the rolled glass fiber mesh 3 to make the rolled glass fiber mesh 3 smoother. As the thickness of the glass fiber mesh 3 rolled up by the reel 215 increases, the pressure roller 235 compresses the spring telescopic rod 233 through the fixed block 234 to move upward, so that the pressure roller 235 can adjust its position according to the thickness of the rolled glass limit mesh. In addition, if the size and position of the reel 215 change, the reel can be installed. When the roller 215 is in the proper pressing position, the corresponding spring telescopic rod 233 and the pressure roller 235 can be slid along the rectangular through groove 232 to a suitable pressing position. Subsequently, the distance between the left and right pressure rollers 235 can be adjusted by rotating the bidirectional threaded telescopic rod 236 to ensure that the left and right pressure rollers 235 can always press against the left and right ends of the reel 215. After the pressure roller 235 is adjusted to a suitable pressing position, the telescopic rod 237 can be stretched to make it plug into the limiting groove. The pressure roller 235 can be limited by adjusting the cooperation between the telescopic rod 237 and the limiting groove, effectively preventing the reel 215 from driving the pressure roller 235 to rotate while winding the glass fiber mesh 3, resulting in the situation that the solidification and pressing effects cannot be exerted.

[0047] See also Figure 1 , Figure 2 , Figure 7 and Figure 8A partition is provided at the rear side of the tensioning assembly, and the partition includes an inclined plate 241 inclined toward the rear and upward, and an evenly arranged partition 242 is provided at the upper end of the inclined plate 241. A strip through groove 246 is opened on the inclined plate 241, and the partition 242 is slidably connected to the strip through groove 246 through a slider 247, wherein the lower ends of the partitions 242 at the leftmost and rightmost ends of the inclined plate 241 are connected with bolts, and the bolts are threadedly connected with nuts after passing through the sliding through grooves, and an upper roller column 243 and a lower roller column 244 arranged up and down are provided between the inclined plate 241 and the tensioning assembly, and the left and right ends of the upper roller column 243 and the lower roller column 244 are rotatably connected to the fixed plate 245 respectively, and the left and right ends of the inclined plate 241 are fixedly connected to the fixed plate 245 respectively, and the fixed plate 245 is symmetrically installed on the upper end of the base 1.

[0048] After the cut glass fiber mesh cloth 3 passes through the tensioning assembly, it passes between the upper roller 243 and the lower roller 244. The cooperation between the upper roller 243 and the lower roller 244 allows the glass fiber mesh cloth 3 to be smoothly transported in the direction of the reel 215, effectively preventing the glass fiber mesh cloth 3 from folding and deforming during the winding process. Subsequently, the glass fiber mesh cloth 3 cut into strips can be separated and guided by the partition plate 242, ensuring that the cut glass fiber mesh cloth 3 is moved to the corresponding reel 215 more accurately and smoothly, so that the cut glass fiber mesh cloths 3 are independent of each other and do not affect each other.

[0049] See also Figure 6 The cutter 113 and the roller 112 are both slidably connected to the corresponding rotating shaft 111 through spline 2. The left and right sides of the cutter 113 are symmetrically provided with a control wheel 115 located between the left and right rollers 112. The control wheel 115 is also slidably connected to the upper rotating shaft 111 through spline 2. The left and right sides of the control wheel 115 are fixedly connected to the corresponding rollers 112 and the cutter 113 through connecting columns 116. The outer ring surface of the control wheel 115 is rotatably connected with a fixing ring 117. The left and right fixing rings 117 corresponding to the same cutter 113 are jointly installed at the lower end of the connecting frame 118. A connecting wheel 119 is provided between the same group of rollers 112 located on the lower rotating shaft 111. The connecting wheel 119 is also slidably connected to the lower rotating shaft 111 through spline 2. The left and right sides of the connecting wheel 119 are fixedly connected to the corresponding rollers 112 through connecting rods 120.

[0050] See also Figure 6 , Figure 7 and Figure 8An inverted L-shaped bracket 248 is connected between the connecting frame 118 and the corresponding partition 242, and a positive L-shaped bracket 249 is connected between the connecting wheel 119 and the corresponding slider 247. A push plate 250 is arranged at the upper end of the horizontal section of the inverted L-shaped bracket 248. Adjustment slots 251 are evenly opened on the push plate 250. The number of the adjustment slots 251 is even and symmetrical. The adjustment slots 251 extend obliquely in the horizontal direction and the front ends are close to the middle of the push plate 250. A sliding column 252 slidably connected to the adjustment slots 251 is installed on the upper end of the inverted L-shaped bracket 248. The left and right ends of the front side of the push plate 250 are connected to the telescopic section of the electric push rod 253. The electric push rod 253 is installed on the upper end of the base 1 through a vertical plate.

[0051] When it is necessary to cut the glass fiber mesh 3 of different widths, the push plate 250 can be pushed forward or backward by the electric push rod 253. During the movement of the push plate 250, the through slot 251 is adjusted to slide with the slide column 252 so that the inverted L-shaped bracket 248 drives the corresponding connecting frame 118 and the partition 242 to move synchronously. When the push plate 250 moves forward, the distance between the inverted L-shaped brackets 248 increases. When the push plate 250 moves backward, the distance between the inverted L-shaped brackets 248 decreases. The connecting frame 118 can make the corresponding control wheel 115 slide synchronously along the upper rotating shaft 111 through the fixing ring 117. The control wheel 115 drives the corresponding roller 112 and the cutter 113 to slide synchronously along the upper rotating shaft 111 through the connecting column 116. At the same time, the partition 242 moves synchronously with the inverted L-shaped bracket 248 along the strip groove 246 through the slider 247, and the slider 247 drives the connecting wheel 119 to move synchronously along the lower rotating shaft 111 through the positive L-shaped bracket 249. The connecting wheel 119 drives the corresponding roller 112 to slide synchronously along the lower rotating shaft 111 through the connecting rod 120 until the cutter 113, the roller 112 and the partition 242 slide synchronously to the appropriate cutting, conveying and separation positions. In addition, the partitions 242 at the leftmost and rightmost ends of the inclined plate 241 can be fixed on the inclined plate 241 through the cooperation between nuts and bolts after sliding to the appropriate positions along the strip groove 246, so as to realize the cutting, pressing and separation guidance of the glass fiber mesh 3 with different width requirements.
