Description

Technical Field

[0001] This application relates to the technical field of water-blocking tape processing, and particularly relates to a feeding device for water-blocking tapes. Background Art

[0002] A water-blocking tape is a tape wrapped around the outer surface of an optical cable or a cable, which plays a role in waterproofing and buffering protection for the optical cable and the cable. Generally, a non-woven fabric is used as the base tape, and a viscous liquid is coated on the non-woven fabric. After the viscous liquid is dried, a water-blocking film will be formed on the surface of the non-woven fabric, thereby obtaining the water-blocking tape.

[0003] When applying glue to the water-blocking tape, a feeding device is used to convey the water-blocking tape. Conventional feeding devices include a support frame and a conveying roller. The conveying roller is rotatably connected to the support frame, and the non-woven fabric is wound around the conveying roller. Under the traction force of the traction device, the non-woven fabric continuously moves, so that the conveying roller conveys the non-woven fabric, and the surface of the non-woven fabric reaches the processing and glue application position.

[0004] Chinese Patent No. CN218478313U discloses a feeding device for water-blocking tapes, which includes a material placing frame and a mounting frame. A raw material roller wound with non-woven fabric is rotatably connected to the material placing frame. The mounting frame is arranged on one side of the material placing frame. A conveying roller is rotatably connected to the mounting frame, and a tensioning component capable of automatically adjusting the tension of the non-woven fabric is rotatably connected to the mounting frame. This feeding device for water-blocking tapes improves the problem that the tension of the non-woven fabric is small and it is easy to be uneven through the tensioning component.

[0005] However, universal wheels are installed at the bottom of the material placing frame of this feeding device, and there is a lack of a connecting structure between the material placing frame and the entire mounting frame. Therefore, the material placing frame is easily affected by external forces and moves on the ground. The movement of the material placing frame will pull the non-woven fabric being fed. After the non-woven fabric is pulled, a large number of wrinkles will appear on the surface. When the wrinkled part moves under the glue application equipment, it is easy to cause uneven glue application on the surface of the non-woven fabric, resulting in an uneven water-blocking effect of the final water-blocking tape and a reduction in the finished product quality of the water-blocking tape, which has obvious deficiencies. Utility Model Content

[0006] In order to improve the finished product quality of the water-blocking tape, this application provides a feeding device for water-blocking tapes.

[0007] The feeding device for water-blocking tapes provided by this application adopts the following technical solutions:

[0008] A water-blocking tape feeding device includes a material placing rack and a mounting rack. A raw material roller wound with non-woven fabric is rotatably connected to the material placing rack. A conveying roller is rotatably connected to the mounting rack. A connecting rack is fixedly connected to one side of the mounting rack close to the material placing rack. The width of the connecting rack is the same as that of the mounting rack, and the opposite ends of the connecting rack and the opposite ends of the mounting rack are on the same straight line. Moving blocks are arranged on both opposite sides of the material placing rack. Moving grooves slidably matched with the moving blocks are formed in the connecting rack. A driving component and a fixing component are arranged on the connecting rack. The driving component is used to drive the material placing rack to move along the length direction of the connecting rack, and the fixing component is used to fix the material placing rack on the connecting rack.

[0009] By adopting the above technical solution, before feeding the non-woven fabric, the driving component adjusts the position of the material placing rack on the connecting rack to ensure that the non-woven fabric is in a tensioned state. Subsequently, the material placing rack is fixed in the connecting rack through the fixing component. At the same time, under the limitation of the moving grooves and the moving blocks, the material placing rack will not move away from the connecting rack. The setting of the connecting rack and the fixing component provides a stable connection structure for the material placing rack, reducing the possibility of the material placing rack moving on the ground, thereby reducing the probability of the non-woven fabric being pulled to generate wrinkles, and further improving the glue coating uniformity of the non-woven fabric and the finished product quality of the water-blocking tape.

[0010] Optionally, the driving component includes a first screw rod and a first guide rod respectively arranged in the two moving grooves. The first screw rod is rotatably connected in the moving groove. One of the moving blocks is threadedly connected to the first screw rod, and the other moving block is slidably connected to the first guide rod. One end of the first screw rod extending out of the moving groove is fixedly connected with a knob.

[0011] By adopting the above technical solution, after the worker winds the non-woven fabric around the conveying roller, the non-woven fabric may be in a loose or tight state. At this time, the worker can rotate the first screw rod through the knob. The rotation of the first screw rod drives the material placing rack to reciprocate in the moving groove. When the non-woven fabric is in a tensioned state, the worker releases the hand and activates the fixing component. The fixing component makes the first screw rod unable to rotate. Therefore, the position of the material placing rack in the moving groove is fixed. Such a setting realizes the switching between the movable and fixed states of the material placing rack on the connecting rack, ensures the tensioned state of the non-woven fabric, and reduces the possibility of the material placing rack moving, thereby improving the finished product quality of the water-blocking tape.

[0012] Optionally, one end of the connecting frame is provided with a cavity. The fixing component includes a gear rotatably connected in the cavity. The gear is coaxially and fixedly connected to the first screw rod. An internal gear ring is meshed with the gear. Limiting blocks are arranged at both opposite ends of the internal gear ring. Limiting grooves which are slidably matched with the limiting blocks are formed in the opposite inner side walls of the cavity. A first spring is arranged in each limiting groove. One end of the first spring is connected to the inner side wall of the limiting groove, and the other end is connected to the limiting block. When the first spring is in its natural state, the internal gear ring is meshed with the gear.

[0013] By adopting the above technical solution, when the first screw rod needs to be rotated, the worker pulls the pull ring outwards to disengage the internal gear ring from the gear. At this time, the first screw rod can be rotated. After the position of the material placing frame on the connecting frame is adjusted, the worker releases the pull ring, and the first spring resets to drive the internal gear ring to mesh with the gear. The internal gear ring cannot rotate in the cavity under the limitation of the limiting block and the limiting groove. Therefore, the gear meshed with the internal gear ring cannot rotate, and the first screw rod coaxially connected to the gear cannot rotate either, thus realizing the fixation of the material placing frame on the connecting frame.

[0014] Optionally, adjusting grooves are formed in both opposite inner side walls of the material placing frame. A second screw rod is rotatably connected in one of the adjusting grooves, and a second guiding rod is arranged in the other adjusting groove. Connecting blocks are arranged at both ends of the raw material roller. The connecting blocks are slidably arranged in the adjusting grooves. One of the connecting blocks is threadedly connected to the second screw rod, and the other connecting block is slidably connected to the second guiding rod. A motor is arranged on the top of the material placing frame. The output shaft of the motor is fixedly connected to the second screw rod.

[0015] By adopting the above technical solution, as the non-woven fabric feeding continues, the non-woven fabric may be in a non-tensioned state again. At this time, the worker can drive the second screw rod to rotate through the motor. The second screw rod rotates to move the connecting block up or down. The connecting block drives the raw material roller to move up or down. During the movement of the raw material roller, the tension state of the non-woven fabric is adjusted, thereby reducing the probability of unevenness of the non-woven fabric during feeding, and further ensuring the uniformity of the glue coating on the surface of the non-woven fabric and improving the finished product quality of the water-blocking belt.

[0016] Optionally, mounting grooves are formed in the opposite surfaces of the connecting blocks. Bearings are arranged in the mounting grooves. Both ends of the raw material roller are respectively connected to the bearings.

[0017] By adopting the above technical solution, the arrangement of the bearings can effectively reduce the friction between the raw material roller and the inner wall of the mounting groove, make the rotation process of the raw material roller more stable, and ensure the smooth progress of the glue coating process of the water-blocking belt.

[0018] Optionally, the bearing is slidably arranged in the installation groove, a plug-in plate is arranged at the bottom of the bearing, a plug-in groove that slides with the plug-in plate is opened on the inner side wall of the installation groove, a connecting assembly is arranged on the connecting block, and the plug-in plate is detachably connected to the plug-in groove through the connecting assembly.

[0019] By adopting the above technical solution, workers can disassemble and assemble the plug-in plate in the plug-in slot through the connecting component, thereby realizing the detachable installation of the raw material roller on the material rack, thereby improving the flexibility of the raw material roller on the material rack.

[0020] Optionally, the connection block is provided with a placement groove connected to the plug-in slot, the connection assembly includes a support block slidably connected to the placement groove, a second spring is provided in the placement groove, one end of the second spring is connected to the placement groove, and the other end is connected to the support block, and in the natural state of the second spring, one end of the support block extends out of the placement groove and abuts against the inner wall of the plug-in slot, and the top surface of the support block contacts the bottom surface of the plug-in block. A shift block is provided on the side of the support block away from the plug-in block.

[0021] By adopting the above technical solution, when it is necessary to remove the raw material roller from the material rack, the worker pulls the shift block, and the shift block drives the supporting block to move in the direction of the placement slot. At this time, the second spring is compressed and the supporting effect of the supporting block on the plug-in block disappears. The worker slides the plug-in block and the bearing off the plug-in block, thereby realizing the removal of the raw material roller from the material rack; when it is necessary to install the raw material roller on the material rack, the plug-in block is slid into the plug-in slot, and then the force on the shift block is cancelled. Under the elastic force of the second spring, the second spring pushes the supporting block to move in the placement slot until the end face of the supporting block abuts against the side wall of the plug-in slot. At this time, the plug-in block will not slide from the plug-in slot under the action of the supporting block, thereby realizing the installation of the raw material roller.

[0022] Optionally, tripods are rotatably connected to the four side walls of the mounting frame, a universal wheel is provided at the bottom end of the tripod, and the tripod is fixed to the mounting frame by the bolts.

[0023] By adopting the above technical solution, when it is necessary to transfer the mounting frame, remove the bolts and rotate the tripod so that the universal wheel is in contact with the ground, and then push the mounting frame to the required position. When loading is required, rotate the tripod again, the tripod drives the universal wheel off the ground, and then fix the universal wheel off the ground with bolts. This arrangement avoids direct contact between the universal wheel and the ground during the loading process, and reduces the possibility of the mounting frame moving on the ground during the loading process.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By providing a connecting frame and a fixing component, the present application offers a stable connection structure for the material placing rack, reducing the possibility of the material placing rack moving on the ground, thereby decreasing the probability of the non-woven fabric being pulled and wrinkled, and further improving the uniformity of the glue coating on the non-woven fabric, and enhancing the finished product quality of the water blocking tape.

[0026] 2. By providing a connecting component, workers can disassemble and assemble the insertion board in the insertion slot through the connecting component, thereby realizing the detachable installation of the raw material roller on the material placing rack and improving the flexibility of the raw material roller on the material placing rack.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following further elaborates on the present application in conjunction with the attached Figure 1-6 for a more detailed description.

[0035] The embodiment of the present application discloses a water blocking tape feeding device.

[0036] Referring toFigure 1 , A water-blocking tape feeding device includes a material placing rack 1 and a mounting rack 2. A raw material roller 101 wound with non-woven fabric 01 is rotatably connected to the material placing rack 1. Along the conveying direction of the non-woven fabric 01, two conveying rollers 21 and two guiding rollers 22 are sequentially rotatably connected to the mounting rack 2.

[0037] Before feeding, the worker passes the non-woven fabric 01 on the raw material roller 101 through the conveying rollers 21 and the guiding rollers 22 in sequence. Subsequently, the non-woven fabric 01 is discharged from the raw material roller 101 through a traction device. Under the conveyance of the guiding rollers 22 and the conveying rollers 21, the non-woven fabric 01 will move to the gluing equipment.

[0038] Refer to Figure 1 , To facilitate the worker to move the mounting rack 2 near the gluing equipment, footrests 23 are rotatably connected to the peripheral side walls of the mounting rack 2. A universal wheel 24 is fixedly connected to the bottom end of the footrest 23. The footrest 23 is fixed to the outer side wall of the mounting rack 2 by a bolt 25.

[0039] When it is necessary to transfer the mounting rack 2, remove the bolt 25 and make the universal wheel 24 abut against the ground. Subsequently, fix the state where the universal wheel 24 abuts against the ground through the bolt 25, and push the mounting rack 2 to the required position. When feeding is required, remove the bolt 25 again and rotate the footrest 23. The rotation of the footrest 23 drives the universal wheel 24 to leave the ground. Subsequently, fix the state where the universal wheel 24 leaves the ground through the bolt 25. Such a setting avoids the direct contact between the universal wheel 24 and the ground during the feeding process, and improves the stability of the mounting rack 2 during the feeding process.

[0040] Refer to Figure 1 and Figure 2 , A connecting frame 3 is arranged between the material placing rack 1 and the mounting rack 2. The connecting frame 3 is fixedly installed at one end of the mounting rack 2 close to the material placing rack 1. The width of the connecting frame 3 is the same as the width of the mounting rack 2, and the opposite ends of the connecting frame 3 and the opposite ends of the mounting rack 2 are on the same straight line. Two moving blocks 102 are fixedly connected to the two end faces of the material placing rack close to the connecting frame 3. A moving groove 31 slidably matched with the moving block 102 is formed on the connecting frame 3. The length direction of the moving groove 31 is parallel to the length direction of the connecting frame 3. A driving component 4 and a fixing component 5 are arranged on the connecting frame 3. The driving component 4 is used to drive the material placing rack 1 to move along the length direction of the connecting frame 3, and the fixing component 5 is used to fix the material placing rack 1 on the connecting frame 3.

[0041] After the worker winds the non-woven fabric 01 around the conveying roller 21 and the guide roller 22 in sequence, the non-woven fabric 01 may be in a loose or tight state. At this time, the worker drives the material rack 1 to slide on the connecting frame 3 through the driving component 4 to adjust the tension state of the non-woven fabric 01, and then fixes the material rack 1 in the connecting frame 3 through the fixing component 5. At the same time, under the restriction of the moving groove 31 and the moving block 102, the material rack 1 will not move away from the connecting frame 3. The setting of the connecting frame 3 and the fixing component 5 provides a stable connection structure for the material rack 1, reduces the possibility of the material rack 1 moving on the ground, thereby reducing the probability of the non-woven fabric 01 being pulled and wrinkled, thereby improving the uniformity of the glue coating on the non-woven fabric 01, and improving the quality of the finished water-blocking tape.

[0042] Reference Figure 1 and Figure 2 The driving assembly 4 includes a first screw rod 41 and a first guide rod 42 respectively arranged in two movable grooves 31, a movable block 102 close to the first screw rod 41 is threadedly connected to the first screw rod 41, and another movable block 102 is slidably connected to the first guide rod 42, and one end of the first screw rod 41 extending out of the movable groove 31 is fixedly connected to a knob 43.

[0043] Reference Figure 2 and Figure 3 A cavity 6 is provided at one end of the connecting frame 3 away from the mounting frame 2, and the fixing assembly 5 includes a gear 51 rotatably connected to the cavity 6, the gear 51 is fixedly connected to one end of the first screw 41 extending to the cavity 6, an inner gear ring 52 is meshedly provided on the gear 51, and two opposite end surfaces of the inner gear ring 52 are fixedly connected to a limiting block 53, and limiting grooves 61 that slide with the limiting block 53 are provided on opposite side walls of the cavity 6, and a first spring 54 is provided in each limiting groove 61, one end of the first spring 54 is fixedly connected to the inner side wall of the limiting groove 61, and the other end is fixedly connected to the limiting block 53. When the first spring 54 is in a natural state, the inner gear ring 52 is meshed with the gear 51, and two pull rings 55 are fixedly connected to the surface of the inner gear ring 52 away from the gear 51, and the two pull rings 55 are symmetrical about the center of the knob 43.

[0044] When the non-woven fabric 01 is in a non-tensioned state, the worker pulls the pull ring 55 outwards to disengage the internal gear ring 52 from the gear 51. Subsequently, by rotating the knob 43, the first screw 41 is driven to rotate. During the rotation of the first screw 41, the moving block 102 threadedly connected to the first screw 41 is driven to move along the moving groove 31. The movement of the connecting block 8 drives the material placing rack 1 to move on the connecting rack 3. When the material placing rack 1 moves, the tension state of the non-woven fabric 01 is adjusted. When the non-woven fabric 01 is tensioned, the worker releases the pull ring 55, and the first spring 54 resets to drive the internal gear ring 52 to engage with the gear 51. The internal gear ring 52 is restricted by the limiting block 53 and the limiting groove 61 and cannot rotate in the cavity 6. Therefore, the gear 51 engaged with the internal gear ring 52 cannot rotate either, and the first screw 41 coaxially connected to the gear 51 cannot rotate either, thus realizing the fixation of the position of the material placing rack 1 on the connecting rack 3.

[0045] Referring to Figure 4 , adjusting grooves 7 are provided on both inner side walls of the material placing rack 1 opposite to each other. A second screw 71 is rotatably connected in one of the adjusting grooves 7, and a second guiding rod 72 is fixedly connected in the other adjusting groove 7. A motor 73 is fixedly installed on the top surface of the material placing rack 1. The output shaft of the motor 73 is coaxially and fixedly connected to the second screw 71. Connecting blocks 8 are fixedly connected to both ends of the raw material roller 101. The connecting blocks 8 are slidably connected in the adjusting grooves 7. The connecting block 8 close to the second screw 71 is threadedly connected to the second screw 71, and the other connecting block 8 is slidably connected to the second guiding rod 72.

[0046] As the feeding of the non-woven fabric 01 continues, the non-woven fabric 01 may be in a non-tensioned state again. At this time, the worker starts the motor 73. The motor 73 drives the second screw 71 to rotate. The rotation of the second screw 71 drives the connecting block 8 threadedly connected to the second screw 71 to move up or down. The connecting block 8 drives the raw material roller 101 to move up or down. During the movement of the raw material roller 101, the tension state of the non-woven fabric 01 is adjusted, thereby reducing the probability of unevenness of the non-woven fabric 01 during feeding, and further ensuring the uniformity of the glue coating on the surface of the non-woven fabric 01 and improving the finished product quality of the water-blocking belt.

[0047] Referring to Figure 4 and Figure 5 , mounting grooves 9 are provided on the opposite surfaces of the two connecting blocks 8. Bearings 91 are slidably connected in the mounting grooves 9. The arrangement of the bearings 91 can effectively reduce the friction between the raw material roller 101 and the inner wall of the mounting groove 9, making the rotation process of the raw material roller 101 more stable. Both ends of the raw material roller 101 are respectively connected to the bearings 91. The bottom of the bearing 91 is fixedly connected to a plug-in board 10. Plug-in grooves 11 slidably matched with the plug-in board 10 are provided on the inner side walls of the mounting grooves 9. Connecting components 12 are provided on each connecting block 8. The plug-in board 10 is detachably connected to the plug-in groove 11 through the connecting component 12.

[0048] Reference Figure 5 and Figure 6 Figure 6 On each connecting block 8, a placing groove 13 communicating with the insertion groove 11 is formed. The connecting component 12 includes a supporting block 121 slidably connected in the placing groove 13. A second spring 122 is arranged in the placing groove 13. One end of the second spring 122 is connected in the placing groove 13, and the other end is connected to the supporting block 121. In the natural state of the second spring 122, one end of the supporting block 121 extends out of the placing groove 13 and abuts against the inner side wall of the insertion groove 11. When the insertion block is supported in the insertion groove 11 by the supporting block 121, the surface of the supporting block 121 abuts against the bottom surface of the insertion block. At the same time, in order to improve the stability of the supporting block 121 during the sliding process, a sliding block (not shown in the figure) is fixedly connected to the surface of the supporting block 121 that abuts against the insertion block, and a sliding groove (not shown in the figure) for sliding cooperation with the sliding block is formed on the bottom surface of the insertion block.

[0049] Reference Figure 5 and Figure 6 Figure 6 When the non-woven fabric 01 is loaded and the raw material roller 101 needs to be replaced, the worker pulls the dial block 123. The dial block 123 drives the supporting block 121 to move towards the placing groove 13. At this time, the second spring 122 is compressed and the supporting effect of the supporting block 121 on the insertion block disappears. The worker slides the insertion block and the bearing 91 out of the insertion block, that is, the disassembly of the raw material roller 101 on the placing rack 1 is realized; when a new raw material roller 101 needs to be installed on the placing rack 1, the insertion block is slid into the insertion groove 11, and then the acting force on the dial block 123 is cancelled. Under the elastic force of the second spring 122, the second spring 122 pushes the supporting block 121 to move in the placing groove 13 until the end surface of the supporting block 121 abuts against the side wall of the insertion groove 11. At this time, the insertion block will not slide out of the insertion groove 11 under the action of the supporting block 121, thus realizing the installation of the raw material roller 101.

[0050] The implementation principle of a water-blocking tape feeding device in an embodiment of the present application is as follows: After a worker winds the non-woven fabric 01 around the conveying roller 21 and the guiding roller 22 in sequence, the non-woven fabric 01 may be in a loose or taut state. At this time, the worker pulls the pull ring 55 outwards to disengage the internal gear ring 52 from the gear 51, and then rotates the first screw 41 by turning the knob 43. The first screw 41 drives the material placing rack 1 to move on the connecting rack 3. When the non-woven fabric 01 is in a taut state, the worker releases the pull ring 55, and the first spring 54 resets to drive the internal gear ring 52 to engage with the gear 51. The internal gear ring 52 cannot rotate in the cavity 6 under the limitation of the limiting block 53 and the limiting groove 61. Therefore, the gear 51 engaged with the internal gear ring 52 cannot rotate either, and the first screw 41 coaxially connected to the gear 51 cannot rotate either, thereby realizing the fixation of the position of the material placing rack 1 on the connecting rack 3. At the same time, under the limitation of the moving groove 31 and the moving block 102, the material placing rack 1 will not move away from the connecting rack 3. The setting of the connecting rack 3 and the fixing component 5 provides a stable connection structure for the material placing rack 1, reducing the possibility of the material placing rack 1 moving on the ground, thereby reducing the probability of the non-woven fabric 01 being pulled to generate wrinkles, and further improving the uniformity of the glue coating on the non-woven fabric 01, and improving the finished product quality of the water-blocking tape.

[0051] The above are all the preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
