Description

Technical Field

[0001] This invention relates to the field of glass fiber cloth production technology, and in particular to an automatic winding device for glass fiber cloth production. Background Technology

[0002] As an important inorganic non-metallic material, fiberglass cloth is widely used in many industrial fields such as building materials, electronics and electrical engineering, aerospace, transportation, and chemical corrosion protection due to its excellent properties such as high strength, high temperature resistance, corrosion resistance, fire resistance, heat insulation, and good electrical insulation. In the continuous production process of fiberglass cloth, after processes such as drawing, weaving, drying, and impregnation, the final fiberglass cloth needs to be neatly and tightly wound onto a roll by a winding equipment for subsequent transportation, storage, and use.

[0003] Currently, automatic winding equipment has become a key component in fiberglass cloth production lines. This type of equipment is mainly used for the automatic winding of fiberglass cloth. However, existing automatic winding equipment still has significant technical defects in practical applications. After a roll of fiberglass cloth is wound up, operators need to manually unload the fully wound roll and reinstall a new empty roll before the next roll can be wound. This reliance on manual roll replacement not only increases the labor intensity of workers, but also takes a long time, seriously affecting the operating efficiency of the entire production line. Summary of the Invention

[0004] In view of this, the present invention provides an automatic winding device for the production of fiberglass cloth, which can solve the shortcomings of existing automatic winding devices that require manual replacement of the roll, which not only increases the labor intensity of workers, but also has low efficiency.

[0005] The technical embodiment of the present invention is as follows: An automatic winding device for producing fiberglass cloth includes a frame and guide rollers. Guide rollers are rotatably arranged at intervals on the frame. Two drive rollers for driving the drum rotation are rotatably arranged on the frame. A feeding frame is installed on the frame. Baffles are symmetrically rotatably arranged inside the feeding frame. A stop mechanism for abutting the baffles is provided on the feeding frame. Limit plates are symmetrically slidably arranged inside the feeding frame. An adjustment mechanism for adjusting the position of the limit plates is provided on the feeding frame. A drive mechanism is provided on the limit plates. Guide rollers are rotatably arranged on the drive mechanism. The frame and drive mechanism are used to move the guide frame, which in turn drives the fully loaded roll to roll. A transfer table and a support table are installed on the side of the frame. Electric rollers are symmetrically rotated on the support table. A glue-applying mechanism and a glue-cutting mechanism are installed on the side of the feeding frame. The glue-applying mechanism is used to apply double-sided tape to the roll, and the glue-cutting mechanism is used to cut the double-sided tape. A linear drive is installed on the side of the feeding frame. A cutting knife for cutting fiberglass cloth is connected to the telescopic rod of the linear drive. The cutting knife is equipped with a pressing mechanism for pressing down the fiberglass cloth.

[0006] Furthermore, the abutting mechanism includes a first electric push rod, a first connecting block, and a first roller. The first electric push rod is symmetrically installed inside the feeding frame. The first connecting block is connected to the telescopic rod of the first electric push rod. The first roller is rotatably installed on the first connecting block. The first roller is used to abut the baffle.

[0007] Furthermore, the adjustment mechanism includes a dual-axis motor and a lead screw. The dual-axis motor is symmetrically arranged on the side of the feeding frame, and the lead screw is connected to the output shaft of the dual-axis motor. The limit plate is threadedly connected to the lead screw.

[0008] Furthermore, the drive mechanism includes a second electric push rod, a fixed block, a stop block, and a spring. The second electric push rod is mounted on the limit plate, and the fixed block is mounted on the telescopic rod of the second electric push rod. The guide frame is rotatably mounted on the fixed block, and a stop block for abutting the guide frame is connected to the fixed block. A spring is connected between the guide frame and the fixed block.

[0009] Furthermore, the adhesive applicator includes an electric slide rail, a fixed plate, a third electric push rod, a connecting frame, a servo motor, an air shaft, and guide wheels. An electric slide rail is installed on the side of the feeding frame. A fixed plate is connected to the slider of the electric slide rail. A third electric push rod is connected to the fixed plate. A connecting frame is connected to the telescopic rod of the third electric push rod. A servo motor is connected to the connecting frame. An air shaft and guide wheels are rotatably mounted on the connecting frame.

[0010] Furthermore, the rubber cutting mechanism includes a fourth electric push rod and a cutting blade. The fourth electric push rod is mounted on the connecting frame, and the cutting blade is connected to the telescopic rod of the fourth electric push rod.

[0011] Furthermore, the pressing mechanism includes a pressing frame and a spring. The pressing frame is slidably mounted on the cutting blade and is used to press down the fiberglass cloth. A spring connects the pressing frame and the cutting blade.

[0012] Furthermore, it also includes a limiting mechanism, which includes a fifth electric push rod, a second connecting block, and a second roller. The fifth electric push rod is mounted on the guide frame, and the second connecting block is connected to the telescopic rod of the fifth electric push rod. The second roller is rotatably mounted on the second connecting block and is used to limit the movement of the drum.

[0013] The present invention has the following advantages: 1. By setting up a feeding frame, baffle, abutment mechanism, drive mechanism, guide frame, transfer table, and support table, the present invention realizes automatic feeding of empty rolls and automatic unloading of full rolls. After a roll of fiberglass cloth is wound up, the equipment can automatically transfer the full roll from the drive roller to the support table and send a new empty roll into the winding station. No manual intervention is required to change the roll, which effectively avoids the downtime caused by manual roll changing in traditional equipment, greatly improves the continuous operation efficiency and automation level of the entire production line, significantly reduces the labor burden of workers, and improves the safety and comfort of operation.

[0014] 2. By setting an adjustment mechanism consisting of a dual-axis motor and a lead screw, the present invention can automatically adjust the distance between the two limit plates to adapt to drums of different lengths, thereby enhancing the versatility and flexibility of the equipment and meeting the production needs of multiple varieties and small batches.

[0015] 3. The present invention is equipped with a limiting mechanism consisting of a fifth electric push rod, a second roller, etc., which presses the roll tightly onto the drive roller at the initial stage of winding, effectively increasing the friction and preventing slippage during startup; and automatically adjusts the limiting force as the roll diameter increases during winding to ensure a smooth winding process and uniform tension, avoiding fabric wrinkles or roll deviation.

[0035] See Figures 9-11 As shown, the adhesive applicator includes an electric slide rail 1401, a fixed plate 1402, a third electric push rod 1403, a connecting frame 1404, a servo motor 1405, an air shaft 1406, and a guide wheel 1407. The electric slide rail 1401 is mounted on the front side of the feeding frame 4. The fixed plate 1402 is connected to the front side of the slider of the electric slide rail 1401. The third electric push rod 1403 is connected to the left front side of the fixed plate 1402. The telescopic rod of the third electric push rod 1403 is connected to... There is a connecting frame 1404; a servo motor 1405 is connected to the lower front part of the connecting frame 1404; an air shaft 1406 is rotatably arranged on the lower rear part of the connecting frame 1404. The air shaft 1406 is used to fix the paper tube wrapped with double-sided tape 103. By controlling the expansion or contraction of the air shaft 1406, the air shaft 1406 can fix or loosen the paper tube (the prior art will not be explained in detail); a guide wheel 1407 is rotatably arranged on the upper side of the connecting frame 1404.

[0036] See Figure 11 As shown, the rubber cutting mechanism includes a fourth electric push rod 1501 and a cutting blade 1502; the fourth electric push rod 1501 is installed on the upper right front part of the connecting frame 1404; the cutting blade 1502 is connected to the telescopic rod of the fourth electric push rod 1501.

[0037] See Figure 12 As shown, the pressing mechanism includes a pressing frame 1801 and a spring 1802; the pressing frame 1801 is slidably disposed on the cutting blade 17, the bottom surface of the pressing frame 1801 is lower than the bottom end of the cutting blade 17, and the pressing frame 1801 is used to press down the fiberglass cloth 101; two springs 1802 are connected between the top of the pressing frame 1801 and the cutting blade 17.

[0038] In use, first, place the paper tube wrapped with double-sided adhesive 103 onto the air shaft 1406. Then, control the air shaft 1406 to expand, fixing the paper tube with double-sided adhesive 103 in place. Next, pull the first end of the double-sided adhesive 103 around the guide wheel 1407 (e.g., Figure 10 As shown), separate the release paper and tape at the beginning of the double-sided tape 103 (the tape surface of the double-sided tape 103 usually carries release paper, which is used to protect the double-sided tape 103 and the tape), and fix the release paper at the beginning of the double-sided tape 103 to the output shaft of the servo motor 1405 with a clamp, and tear off the excess tape at the beginning of the double-sided tape 103 (leaving only the new beginning of the tape at the top of the double-sided tape 103). In this way, the preparation of the double-sided tape 103 is completed. Then, based on the length of the drum 102, the dual-axis motor 801 drives the lead screw 802 to rotate or reverse, thereby causing the two limiting plates 7 to move closer or further apart, thus adjusting the distance between the two limiting plates 7 to match the length of the drum 102. After adjustment, an appropriate amount of drum 102 is placed into the feeding frame 4, so that the lowest drum 102 in the feeding frame 4 contacts the baffle 5, thereby the baffle 5 blocks the drum 102 in the feeding frame 4, and the two limiting plates 7 limit the drum 102 in the feeding frame 4. In this way, the preparation of the drum 102 is completed. Next, the produced fiberglass cloth 101 is wrapped around the upper guide roller 2 from right to left, and then the first end of the fiberglass cloth 101 is wrapped around the two guide rollers 2 from below. Then, the first end of the fiberglass cloth 101 is pulled through the two drive rollers 3 (e.g., Figure 2 As shown), until the first end of the fiberglass cloth 101 is placed flat on the top of the transfer table 11, the preparation of the fiberglass cloth 101 is completed. Next, the fiberglass cloth 101 is wound up: the connecting frame 1404, servo motor 1405, air shaft 1406, and guide wheel 1407 are driven to move backward by the third electric push rod 1403, thereby driving the paper tube wrapped with double-sided adhesive 103 to move backward. This allows the connecting frame 1404 and the paper tube wrapped with double-sided adhesive 103 to pass through the through hole and enter the feeding frame 4. When the tape of double-sided adhesive 103 contacts the bottom of the lowest roll 102 in the feeding frame 4, the tape will adhere to the bottom of the lowest roll 102. Then, as the connecting frame 1404 and the paper tube wrapped with double-sided adhesive 103 continue to move backward, the tape of double-sided adhesive 103 can be made to stick along the bottom of the lowest roll 102. While the connecting frame 1404 moves backward, the servo motor 1405, air shaft 1406, and guide wheel 1407 are simultaneously controlled. The output shaft of the machine 1405 rotates, enabling the output shaft of the servo motor 1405 to synchronously wind the release paper of the double-sided adhesive 103. After the tape of the double-sided adhesive 103 is applied along the bottom of the lowest roll 102, the fourth electric push rod 1501 drives the cutting blade 1502 to move upward, cutting the tape of the double-sided adhesive 103. Subsequently, the electric slide rail 1401 drives the fixing plate 1402 to move downward, thereby driving the third electric push rod 1403, the connecting frame 1404, the servo motor 1405, the air shaft 1406, and the guide wheel 1407 to move downward, which in turn drives the paper roll with the double-sided adhesive 103 to move downward, so that the tape of the double-sided adhesive 103 is separated from the bottom of the lowest roll 102 by a certain distance. The first electric push rod 1403 drives the connecting frame 1404, servo motor 1405, air shaft 1406, and guide wheel 1407 to move forward and reset, thereby moving the paper tube wrapped with double-sided adhesive 103 forward and reset, so that the connecting frame 1404 and the paper tube wrapped with double-sided adhesive 103 pass through the through hole of the feeding frame 4. Then, the electric slide rail 1401 drives the fixing plate 1402 to move upward and reset, thereby driving the third electric push rod 1403, connecting frame 1404, servo motor 1405, air shaft 1406, and guide wheel 1407 to move upward and reset, thereby driving the paper tube wrapped with double-sided adhesive 103 to move upward and reset. After that, the first electric push rod 601 drives the first connecting block 602 and the first roller 603 to move downward. This causes the first roller 603 to separate from the baffle 5, so that the first roller 603 no longer presses against the bottom of the baffle 5. This allows the baffle 5 to rotate and open under gravity, causing the lowest winding drum 102 in the loading frame 4 to fall downwards under the guidance of the guide frame 10. After the lowest winding drum 102 in the loading frame 4 falls downwards, the first electric push rod 601 drives the first connecting block 602 and the first roller 603 to move upwards and reset, causing the first roller 603 to contact the baffle 5. This causes the first roller 603 to press the baffle 5 in reverse and close, causing the first roller 603 to press against the bottom of the baffle 5 again. The baffle 5 then blocks the remaining winding drum 102 in the loading frame 4. When the lowest winding drum 102 falls downwards onto the two drive rollers 3 under the guidance of the guide frame 10...The bottommost spool 102 will disengage from the guide frame 10 and come into contact with the flat-lying fiberglass cloth 101. The bottommost spool 102 will then adhere the fiberglass cloth 101 to the adhesive tape at its bottom. Subsequently, the drive roller 3 will rotate counterclockwise, causing the drive roller 3 to rotate clockwise through friction. This allows the spool 102 to wind up the fiberglass cloth 101 via the adhesive tape, thus completing the winding operation of the fiberglass cloth 101. As the drum 102 gradually winds up the fiberglass cloth 101, it gradually rises due to the increase in fiberglass cloth 101, causing it to gradually return to the guide frame 10. Once the drum 102 is full of fiberglass cloth 101, the drive roller 3 is stopped from rotating counterclockwise. Then, the second electric push rod 901 drives the fixing block 902, the abutment block 903, the spring piece 904, and the guide frame 10 to move to the left. At this time, the drum 102, now full of fiberglass cloth 101, applies a counterclockwise rotational force to the guide frame 10. However, because the abutment block 903 blocks the guide frame 10, the guide frame 10 cannot rotate counterclockwise. Therefore, the guide frame 10 can only push the drum 102, now full of fiberglass cloth 101, to roll to the left, thus allowing the full drum to rotate. The roll 102 of fiber cloth 101 gradually transfers from the two drive rollers 3 to the top of the transfer table 11, and then from the top of the transfer table 11 to the top of the support table 12, finally positioned between the tops of the two electric rollers 13. Then, the second electric push rod 901 drives the fixing block 902, the abutment block 903, the spring piece 904, and the guide frame 10 to move to the right and reset. At this time, the roll 102 fully loaded with fiber cloth 101 applies a clockwise rotational thrust to the guide frame 10, causing the guide frame 10 to rotate clockwise. The spring piece 904 deforms, causing the guide frame 10 to separate from the abutment block 903. When the guide frame 10 separates from the roll 102 fully loaded with fiber cloth 101, the spring piece 904 returns to its original shape, and the spring piece 904 drives the guide frame 10 to rotate counterclockwise. The rotary reset allows the guide frame 10 to re-engage with the stop block 903. Then, the linear actuator 16 drives the cutting blade 17 downwards, causing the pressing frame 1801 and spring 1802 to move downwards. When the pressing frame 1801 contacts the fiberglass cloth 101 on top of the transfer table 11, the fiberglass cloth 101 blocks the downward movement of the pressing frame 1801 and spring 1802. As the cutting blade 17 continues to move downwards, the spring 1802 compresses. Through the deformation of the spring 1802, it applies pressure to the pressing frame 1801, thus pressing the fiberglass cloth 101 on top of the transfer table 11 tightly. Then, when the cutting blade 17 contacts the fiberglass cloth 101, the cutting blade 17... The fiberglass cloth 101 is cut and enters the groove of the transfer table 11. After the fiberglass cloth 101 is cut, the cutting blade 17 is driven to move upward and reset by the linear driver 16. During this period, the spring 1802 gradually returns to its original state. When the spring 1802 returns to its original state, the cutting blade 17 drives the spring 1802 and the pressing frame 1801 to move upward and reset. Then, the electric roller 13 is controlled to rotate counterclockwise, so that the electric roller 13 drives the roll 102 full of fiberglass cloth 101 to rotate clockwise through friction until the end of the fiberglass cloth 101 is completely rolled onto the roll 102. Then, the electric roller 13 is controlled to stop rotating counterclockwise. In this way, the roll 102 full of fiberglass cloth 101 can be transferred. Then repeat the above winding operation of the fiberglass cloth 101, so that the next roll 102 can automatically wind up the subsequent fiberglass cloth 101, thereby realizing the automatic replacement of the roll 102. Then the roll 102 full of fiberglass cloth 101 is removed from the support platform 12. When the double-sided adhesive 103 on the paper tube is used up, the air shaft 1406 is controlled to retract, causing the air shaft 1406 to release the empty paper tube. Then, the empty paper tube is removed from the air shaft 1406, and the release paper wound on the output shaft of the servo motor 1405 is cleaned. Then, a new paper tube with double-sided adhesive 103 is taken out and the above preparation operation of double-sided adhesive 103 is repeated. In this way, the paper tube with double-sided adhesive 103 can be replaced.

[0039] See Figure 13 As shown, it also includes a limiting mechanism, which includes a fifth electric push rod 19, a second connecting block 20, and a second roller 21; the fifth electric push rod 19 is installed on the lower part of the two guide frames 10 on the side away from each other; the second connecting block 20 is connected to the telescopic rod of the fifth electric push rod 19; the second roller 21 is rotatably arranged on the second connecting block 20, and the second roller 21 is used to limit the drum 102.

[0040] By setting a limiting mechanism, when the lowest roll 102 falls onto the two drive rollers 3, the second connecting block 20 and the second roller 21 can be driven by the fifth electric push rod 19 to move closer to the roll 102. This allows the second roller 21 to press the roll 102 onto the drive roller 3, ensuring that the drive roller 3 can rotate the roll 102 through friction. This prevents slippage between the drive roller 3 and the roll 102 due to insufficient friction. Then, as the roll 102 gradually winds up the fiberglass cloth 101, the second connecting block 20 and the second roller 21 can be driven by the fifth electric push rod 19 to move away from the roll 102 and reset, so that the second roller 21 does not affect the winding of the fiberglass cloth 101 on the roll 102.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention 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 solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
