Description

Technical Field

[0001] This invention relates to the field of fireproof roller shutter fabric conveying technology, specifically a conveying and straightening device for the production of fireproof roller shutter fabric. Background Technology

[0002] Fire-resistant roller shutter fabric is a material made of inorganic fire-resistant fibers through special processing. It has fireproof, smoke-proof and heat-insulating functions. In the production of fire-resistant roller shutter fabric, the fire-resistant fiber cloth needs to be conveyed and sewn with other materials.

[0003] For example, a polyester needle-punched fabric tensioning and conveying device, as disclosed in announcement number CN220641939U, involves placing the polyester needle-punched fabric on top of guide rollers one and two, and passing it through the bottom of tension rollers. During conveying, a motor is activated to drive the tension rollers downwards, tensioning the polyester needle-punched fabric and preventing it from becoming too loose to be conveyed. The device also incorporates clamping rollers to hold the polyester needle-punched fabric, further enhancing the tensioning effect. This allows the polyester needle-punched fabric to be tensioned and conveyed during winding, preventing it from becoming too loose to be conveyed. The purpose of conveying is to tighten the fabric, but in actual use, the tensioning rollers are used to tighten the fabric during the conveying process. If the fabric deviates during the conveying process, it cannot be straightened, causing the fabric to deviate during conveying and making subsequent conveying inconvenient. Since tightening the fabric once during the conveying process does not completely solve the problem of looseness, multiple tightening operations may be required. The operation is too frequent and inconvenient to use. Moreover, when the fabric is loose, it is easy for it to deviate due to the looseness, affecting the normal conveying of the fabric, which has certain defects in use.

[0004] Therefore, we propose a conveying and straightening device for the production of fireproof roller shutter fabric in order to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying and straightening device for the production of fireproof roller shutter fabric, in order to solve the problems mentioned in the background art. In the process of conveying fabric, tensioning is achieved by moving tension rollers. However, if the fabric deviates during conveying, it cannot be straightened, resulting in deviations in the fabric conveying process and hindering subsequent conveying. Furthermore, since one tensioning operation during conveying does not completely solve the problem of looseness, multiple tensioning operations may be required, making the operation too frequent and inconvenient to use. Moreover, when the fabric becomes loose, conveying it can easily lead to deviations, affecting the normal conveying of the fabric.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying and straightening device for the production of fireproof roller shutter fabric, comprising a workbench, wherein a support frame is fixedly installed at the bottom of the workbench; Also includes: A movable plate is set on the top side of the workbench.

Compression springs are sleeved on the upper outer sides of the two fixed rods, and the two ends of the compression springs are fixedly connected to the movable block and the mounting groove, respectively. Conveyor wheels are rotatably connected between the two fixed frames and between the two movable blocks. At the same time, two fixed frames on one side are fixedly connected to the worktable, and two fixed frames on the other side are fixedly connected to the movable plate.

[0008] By adopting the above technical solution, the moving plate can be moved to the right regardless of whether the moving plate moves forward or backward.

[0009] Preferably, a movable rod is symmetrically installed on one side of the movable plate, and a positioning block is symmetrically slidably connected to the outside of each of the two movable rods. The positioning block is fixedly connected to the worktable. At the same time, a return spring is sleeved on the outside of the movable rod, and one end of the return spring is fixedly connected to the positioning block on one side. The other end of the return spring is fixedly installed with a fixing ring, and the fixing ring is fixedly connected to the movable rod. At the same time, a support block is symmetrically slidably connected to the outside of the movable rod, and the two support blocks are fixedly connected to the worktable. A mounting frame is fixedly installed on one side of the worktable, and an electric push rod is fixedly installed inside the upper part of the mounting frame.

[0011] Preferably, a mounting plate is fixedly installed on one side of the movable plate between the two movable rods, and a rack is fixedly installed on one side of the mounting plate. A positioning frame is fixedly installed on the top of the worktable on one side of the mounting plate. A rotating sleeve is rotatably connected inside the positioning frame, and a drive gear is fixedly installed on the lower outside of the rotating sleeve. The drive gear meshes with the rack, and a connecting shaft is provided inside the rotating sleeve.

[0013] Preferably, a limiting frame is fixedly installed on the top of the worktable above the positioning frame, and a threaded rod is rotatably connected to the upper center of the limiting frame.

[0018] By adopting the above technical solution, if the moving plate is reset after the fabric is tensioned, it will not cause the threaded rod to reverse, thus avoiding the need for the tensioning wheel to reset after it rises.

[0019] Preferably, a second rotating component is fixedly installed at the top of each of the two rotating rods, and a cylinder is fixedly installed on one side of the top of the U-shaped frame located on both of the two second rotating components.

[0022] By adopting the above technical solution, the continuous movement of the movable plate can blow air onto the laser emitter.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the conveying and straightening equipment for the production of fireproof roller shutter cloth has a straightening component set on one side of the top of the workbench, so that when the fireproof fiber cloth is conveyed, it can be straightened when the conveying is deviated, and the fireproof fiber cloth can be tensioned at the same time to avoid loosening, which can reduce the tensioning steps, avoid the conveying deviation from affecting the subsequent processing work, and improve practicality. 1. A straightening component is installed on one side of the top of the workbench. When conveying the fireproof fiber cloth, one end of the cloth is lowered from the feeding rack and passes through two sets of conveyor wheels from left to right, positioned above the tensioning wheel, with the compression spring in a compressed state. A drive motor is installed on one side of the lower right conveyor wheel for driving. The conveyor wheel and the fixed frame are connected by a damping bearing. When the right conveyor wheel drives the conveying of the cloth, the cloth is less likely to become loose. The cloth is positioned by two laser emitters and the edge during conveying. If there is a deviation in the conveying, the laser emitter sends a signal, which drives the movable rod to move through the electric push rod. This movable rod drives the movable plate to move, thereby changing the position of the cloth conveying and straightening the conveying path. The movable plate may move back and forth during the adjustment process. Whether the movable plate moves forward or backward, it can drive the rotating rod to rotate through the meshing of the toothed plate and the rotating gear. After the rotating rod rotates, it can push the movable plate to move. After the movable plate moves, it drives the movable rod to slide on the positioning block. The moving plate moves and stretches the return spring. After the moving plate moves, it can drive the mounting plate to move. After the mounting plate moves, it can drive the rotating sleeve to rotate through the connection between the rack and the drive gear, which in turn drives the connecting shaft to rotate, causing the threaded rod to rotate. After the threaded rod rotates, it can drive the threaded sleeve to move upward. After the threaded sleeve moves upward, it drives the connecting plate to move upward, which in turn drives the lifting plate to move upward, causing the tensioning wheel to move upward and tension the conveyed fabric. After the tensioning wheel moves upward and tensions, it drives the column rod to slide on the lifting plate and stretch the tensioning spring. This allows for continuous tensioning during the continuous straightening of the fabric. After tensioning, the fabric is less likely to become loose during conveying, and it can also reduce the occurrence of deviation. The straightening component can straighten the fireproof fiber cloth when it deviates during conveying, and at the same time, it can tighten the fireproof fiber cloth to prevent loosening. It can reduce the tensioning steps, avoid conveying deviations from affecting subsequent processing work, and improve practicality. 2. During continuous straightening operations, the movable plate moves continuously, which can push the moving plate to move. After the moving plate moves, it drives the rotating sleeve to rotate through the meshing of the rack and the drive gear. During the rotation of the rotating sleeve, the locking teeth just engage inside the ratchet groove, which in turn drives the connecting shaft to rotate. When the movable plate moves and then resets, the first rotating component resets. After the first rotating component resets and rotates, the moving plate resets and moves under the action of the reset spring. At this time, it will drive the rotating sleeve to rotate in the opposite direction. At this time, the locking teeth can be continuously pushed by the ratchet groove under the action of the torsion spring. At this time, the rotation of the rotating sleeve will not drive the connecting shaft to rotate. Therefore, when the moving plate resets after the fabric is tensioned, it will not drive the threaded rod to reverse, thus avoiding the need to reset after the tensioning wheel rises. 3. During continuous rotation, the two rotating rods drive the second rotating component to rotate. The rotation of the second rotating component then pushes the push rod to move. The push rod then drives the reciprocating rod to slide on the cylinder and compress the support spring, pushing the piston to slide inside the cylinder. At this time, the one-way valve inside the air inlet pipe closes, and the one-way valve inside the air outlet pipe opens, allowing air from inside the cylinder to be forced into the air outlet pipe and ejected through the air outlet nozzle. This allows the air to be accelerated outwards under the action of the air outlet nozzle, effectively venting the laser emitter and preventing dust from adhering to the bottom of the laser emitter. After the rotating rods return to their original position, the piston and reciprocating rod return to their original position under the action of the support spring. At this time, the one-way valve inside the air inlet pipe opens, and the one-way valve inside the air outlet pipe closes, allowing outside air to be drawn into the cylinder. This allows air to be blown onto the laser emitter when straightening the fabric, preventing dust from adhering during the sewing of the fireproof roller shutter fabric, thus avoiding affecting the accuracy of the laser emitter and the positioning accuracy of the fireproof roller shutter fabric.

A positioning frame 214 is fixedly installed on the top of the worktable 1 on one side of the mounting plate 213. A rotating sleeve 216 is rotatably connected inside the positioning frame 214. A drive gear 217 is fixedly installed on the lower outside of the rotating sleeve 216. The drive gear 217 meshes with the rack 215. A connecting shaft 218 is provided inside the rotating sleeve 216. A limiting frame 221 is fixedly installed on the top of the workbench 1 above the positioning frame 214.

The bottom end of the threaded rod 223 is fixedly connected to the connecting shaft 218. A threaded sleeve 224 is sleeved on the outside of the threaded rod 223. A connecting plate 225 is fixedly installed on the outside of the threaded sleeve 224. A connecting rod 226 is symmetrically installed on the top of the connecting plate 225. The connecting rod 226 is slidably connected to the limiting frame 221. The top ends of the two connecting rods 226 pass through the limiting frame 221 and are fixedly installed with the lifting plate 227. The lifting plate 227 is symmetrically slidably connected with the column rods 228. The top ends of the two column rods 228 are fixedly installed with the connecting frame 229. The tension wheel 230 is rotatably connected inside the connecting frame 229. The lower outer surface of the two column rods 228 is fitted with a tension spring 231. One end of the tension spring 231 is fixedly connected to the lifting plate 227, and the other end of the tension spring 231 is fixedly installed with a connecting block 232. The connecting block 232 is fixedly connected to the column rod 228.

[0028] Example 1: As Figures 1-7As shown, a straightening component 2 is installed on one side of the top of the workbench 1. When conveying the fireproof fiber cloth, one end of the cloth is lowered from the feeding rack and passes through two sets of conveyor wheels 113 from left to right, positioned above the tensioning wheel 230, with the compression spring 112 in a compressed state. A drive motor is installed on one side of the lower right conveyor wheel 113 for driving. The conveyor wheel 113 is connected to the fixed frame 108 by a damping bearing. When the right conveyor wheel 113 drives the conveying of the cloth, the cloth is less likely to become loose. The cloth is positioned by two laser emitters 203 and the edge during conveying. When a deviation occurs, the laser emitter 203 sends a signal, which drives the movable rod 104 to move via the electric push rod 107. This causes the movable rod 104 to move the movable plate 102, thereby changing the position of the fabric conveyor and straightening the conveyor path. During the adjustment process, the movable plate 102 may move back and forth. Regardless of whether the movable plate 102 moves forward or backward, it can drive the rotating rod 204 to rotate through the meshing of the toothed plate 205 and the rotating gear 206. After the rotating rod 204 rotates, it can push the movable plate 208 to move. After the movable plate 208 moves, it drives the movable rod 209 to the positioning block. The sliding and stretching return spring 211 on 210 causes the moving plate 208 to move, which in turn moves the mounting plate 213. The mounting plate 213, through the connection between the rack 215 and the drive gear 217, drives the rotating sleeve 216 to rotate, which in turn drives the connecting shaft 218 to rotate, causing the threaded rod 223 to rotate. The rotation of the threaded rod 223 then drives the threaded sleeve 224 to move upwards, which in turn drives the connecting plate 225 to move upwards, which in turn drives the lifting plate 227 to move upwards via the connecting rod 226, causing the tensioning wheel 230 to move upwards and adjust the conveyed fabric. After tensioning, the tensioning wheel 230 moves upward to tension, driving the column rod 228 to slide on the lifting plate 227 and stretching the tension spring 231. This allows for continuous tensioning during the process of straightening the fabric. After tensioning, the fabric is less likely to become loose during transport, and the occurrence of deviation can be reduced. The straightening component 2 can straighten the fireproof fiber cloth when it deviates during transport, and at the same time, it can tighten the fireproof fiber cloth to prevent loosening. This reduces the number of tensioning steps, avoids deviations in transport that may affect subsequent processing, and improves practicality.

[0029] The rotating sleeve 216 has a ratchet groove 219 inside, and the connecting shaft 218 has symmetrical connecting grooves on the outside. The connecting groove has a locking tooth 220 hinged inside, and the locking tooth 220 engages with the ratchet groove 219. A torsion spring is provided at the connection between the locking tooth 220 and the connecting groove.

[0030] Example 2: Figures 7-8As shown, during the continuous straightening operation, the movable plate 102 moves continuously, which pushes the movable plate 208 to move. After the movable plate 208 moves, it drives the rotating sleeve 216 to rotate through the meshing of the rack 215 and the drive gear 217. During the rotation of the rotating sleeve 216, the locking teeth 220 just engage with the inside of the ratchet groove 219, which in turn drives the connecting shaft 218 to rotate. When the movable plate 102 moves and then resets, the first rotating component 207 resets. After the first rotating component 207 resets and rotates, the movable plate 208 resets and moves under the action of the reset spring 211. At this time, it will drive the rotating sleeve 216 to rotate in the opposite direction. At this time, under the action of the torsion spring, the ratchet groove 219 can continuously push the locking teeth 220 to rotate. At this time, the rotation of the rotating sleeve 216 will not drive the connecting shaft 218 to rotate. Therefore, when the movable plate 208 resets after the fabric is tensioned, it will not drive the threaded rod 223 to reverse, thus avoiding the tensioning wheel 230 from rising and then resetting.

[0031] The top ends of the two rotating rods 204 are each fixedly mounted with a second rotating component 233, and the top of the U-shaped frame 201 is fixedly mounted with a cylinder 234 on one side of the two second rotating components 233. The cylinder 234 is slidably connected to a piston 238, and a reciprocating rod 235 is fixedly mounted on one side of the piston 238. The reciprocating rod 235 is slidably connected to the cylinder 234, and a push rod 236 is fixedly mounted on the end of the reciprocating rod 235 away from the piston 238. The push rod 236 is slidably connected to the second rotating component 233. A support spring 237 is sleeved on the outer side of the reciprocating rod 235, and the two ends of the support spring 237 are fixedly connected to the cylinder 234 and the push rod 236 respectively. Both cylinders 234 have an air inlet pipe 239 connected through to one side of their tops, and both cylinders 234 have an air outlet pipe 240 connected through to the side of their bodies that are far apart from each other. Both the air inlet pipe 239 and the air outlet pipe 240 have a one-way valve inside. Both L-shaped frames 202 have limit blocks 241 symmetrically installed on their inner sides. The limit blocks 241 are fixedly connected to the air outlet pipe 240, and the end of the air outlet pipe 240 that is far away from the cylinder 234 is fixedly connected to an air outlet nozzle.

[0032] Example 3: Figures 3-4 and Figure 9As shown, the two rotating rods 204, during continuous rotation, can drive the second rotating component 233 to rotate. After the second rotating component 233 rotates, it will push the push rod 236 to move. After the push rod 236 moves, it will drive the reciprocating rod 235 to slide on the cylinder 234 and compress the support spring 237, pushing the piston 238 to slide inside the cylinder 234. At this time, the one-way valve inside the air inlet pipe 239 is closed, and the one-way valve inside the air outlet pipe 240 is opened, so that the air inside the cylinder 234 is pushed into the air outlet pipe 240 and ejected through the air outlet nozzle. Under the action of the air outlet nozzle, the air can be accelerated and ejected, which can just be directed at the laser emitter 203. The air outlet prevents dust from adhering to the bottom of the laser emitter 203. After the rotating rod 204 rotates and resets, the piston 238 and reciprocating rod 235 reset and move under the action of the support spring 237. At this time, the one-way valve inside the air inlet pipe 239 opens and the one-way valve inside the air outlet pipe 240 closes, allowing outside air to be drawn into the cylinder 234. This allows air to be blown onto the laser emitter 203 when straightening the fabric, preventing dust from adhering. This is especially important in the sewing of fireproof roller shutter fabric, as it avoids affecting the accuracy of the laser emitter 203 and the accuracy of the fireproof roller shutter fabric conveying and positioning.

[0033] Working principle: When using this conveying and straightening equipment for the production of fireproof roller shutter fabric, firstly, according to... Figures 1-9As shown, when conveying the fireproof fiber cloth, one end of the cloth is lowered from the feeding rack and passes through two sets of conveyor wheels 113 from left to right, positioned above the tension wheel 230, with the compression spring 112 in a compressed state. A drive motor is installed on one side of the lower right conveyor wheel 113 for driving. The conveyor wheel 113 is connected to the fixed frame 108 by a damping bearing. When the right conveyor wheel 113 drives the conveying of the cloth, the cloth is less likely to become loose. During the conveying process, the cloth is positioned against the edge by two laser emitters 203. If there is a deviation in the conveying, the laser emitter 203 sends a signal, which drives the movable rod 104 to move via the electric push rod 107. This causes the movable rod 104 to move the movable plate 102, thereby changing the position of the cloth conveying and straightening the conveying path. The movable plate 102 may move back and forth during the adjustment process. Whether the movable plate 102 moves forward or backward, it can drive the rotating rod 204 to rotate through the meshing of the toothed plate 205 and the rotating gear 206. After rotation, the moving plate 208 can be moved. After the moving plate 208 moves, the moving rod 209 slides on the positioning block 210 and stretches the return spring 211. After the moving plate 208 moves, the mounting plate 213 can be moved. After the mounting plate 213 moves, it can drive the rotating sleeve 216 to rotate through the connection between the rack 215 and the drive gear 217. This can then drive the connecting shaft 218 to rotate, causing the threaded rod 223 to rotate. After the threaded rod 223 rotates, it can drive the threaded sleeve 224 to move upward. After the threaded sleeve 224 moves upward, it can drive the connecting plate 225 to move upward. This can then drive the lifting plate 227 to move upward through the connecting rod 226, causing the tensioning wheel 230 to move upward and tension the conveyed fabric. After the tensioning wheel 230 moves upward and tensions, it drives the column rod 228 to slide on the lifting plate 227 and stretch the tension spring 231. This allows the fabric to be continuously tensioned during the process of straightening it. After tensioning, the fabric is less likely to become loose during the conveying process, and the occurrence of deviation can also be reduced. During the continuous straightening operation, the movable plate 102 moves continuously, which pushes the movable plate 208 to move. After the movable plate 208 moves, it drives the rotating sleeve 216 to rotate through the meshing of the rack 215 and the drive gear 217. During the rotation of the rotating sleeve 216, the retaining teeth 220 just engage with the inside of the ratchet groove 219, thereby causing the rotating sleeve 216 to rotate and drive the connecting shaft 218 to rotate. When the movable plate 102 returns to its original position after moving, the first rotating component 207 returns to its original position. After the first rotating component 207 returns to its original position, the movable plate 208... The reset movement is initiated by the reset spring 211, which causes the rotating sleeve 216 to rotate in the opposite direction. At this time, the ratchet groove 219 continuously moves the 220 teeth under the action of the torsion spring. The rotation of the rotating sleeve 216 does not cause the connecting shaft 218 to rotate. Therefore, if the moving plate 208 resets after tensioning the fabric, it will not cause the threaded rod 223 to reverse, thus preventing the tensioning wheel 230 from resetting after rising. During the continuous rotation of the two rotating rods 204, the second rotating component 233 can be driven to rotate. After rotation, the push rod 236 will move. The movement of the push rod 236 will cause the reciprocating rod 235 to slide on the cylinder 234 and compress the support spring 237, pushing the piston 238 to slide inside the cylinder 234. At this time, the one-way valve inside the air inlet pipe 239 is closed, and the one-way valve inside the air outlet pipe 240 is opened, allowing air from inside the cylinder 234 to be forced into the air outlet pipe 240 and ejected through the air outlet nozzle. This allows the air to be accelerated outwards under the action of the air outlet nozzle, ensuring proper airflow to the laser emitter 203 and preventing dust from adhering to the laser emitter 203. At the bottom, after the rotating rod 204 rotates and resets, the piston 238 and the reciprocating rod 235 reset and move under the action of the support spring 237. At this time, the one-way valve inside the air inlet pipe 239 opens and the one-way valve inside the air outlet pipe 240 closes, allowing outside air to be drawn into the cylinder 234. This allows air to be blown onto the laser emitter 203 when the fabric is straightened, preventing dust from adhering during the sewing of the fireproof roller shutter fabric. This also prevents dust from affecting the accuracy of the laser emitter 203 and the accuracy of the fireproof roller shutter fabric conveying and positioning.
