[0002] In the production process of glass fiber cloth, the slitting device is an indispensable equipment. Its main function is to cut the wide glass fiber cloth into narrow cloth that meets specific width requirements.

[0003] However, existing slitting devices for glass fiber cloth production typically utilize a fixed cutting mechanism. Specifically, existing cutting machines typically utilize bolts and a slide to secure the cutting mechanism. This means that the cutting width is fixed during the cutting process and cannot be adjusted to meet actual needs. To cut glass fiber cloth of varying widths, the bolts must be removed and the position of the entire cutting mechanism and the bottom support seat must be adjusted, which is inconvenient and reduces production efficiency.

[0004] Furthermore, existing slitting devices often lack flexibility during the cutting process. Since the cutting mechanism is fixed in position, operators need to manually adjust the position of the glass fiber cloth when the width of the glass fiber cloth to be cut changes, which not only increases the complexity of the operation but also may lead to a decrease in cutting accuracy.

[0005] In view of the above problems, a slitting device for producing glass fiber cloth is now designed. Utility Model Content

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] An embodiment of the present application provides a slitting device for glass fiber cloth production, which can solve the problem in the related art that existing slitting devices for glass fiber cloth production usually use a fixed cutting mechanism, which makes it inconvenient to adjust the position of the cutting mechanism and affects work efficiency.

[0028] See also Figure 1-Figure 3 A slitting device for producing glass fiber cloth includes: a support frame 1, a plurality of guide rollers 2 are rotatably provided on the support frame 1, an unwinder 3 and a reel 4 are respectively provided at both ends of the support frame 1, a slitting assembly 5 is provided on the support frame 1, the unwinder 3 is used for unwinding the glass fiber cloth, the slitting assembly 5 is used for cutting the glass fiber cloth, and the reel 4 is used for rewinding the slit glass fiber cloth; the slitting assembly 5 includes a linear slide rail 51 provided on the support frame 1, a lifting member 52 is provided at the bottom of the linear slide rail 51, a cutting machine 53 is provided at the bottom of the lifting member 52, the linear slide rail 51 is used to drive the lifting member 52 to move along the length of the support frame 1, the lifting member 52 is used to drive the cutting machine 53 to move up and down, and the cutting machine 53 is used to cut the glass fiber cloth.

[0029] First, the glass fiber cloth begins to unwind from the unwinder 3 and is guided and flattened by several guide rollers 2 provided on the support frame 1. The guide rollers 2 ensure the stability and accuracy of the glass fiber cloth during the transmission process, avoiding cutting errors caused by wrinkles or deviations of the cloth.

[0030] Next, the glass fiber cloth enters the area of ​​the slitting assembly 5, and the linear slide 51 drives the lifting member 52 and the cutter 53 at the bottom to move horizontally, while the lifting member 52 is responsible for the vertical movement of the cutter 53. By adjusting the height of the lifting member 52, the distance between the cutter 53 and the glass fiber cloth can be precisely controlled to ensure the accuracy and depth of the cutting.

[0031] Finally, the cut glass fiber cloth is transferred to the winder 4, which winds up the cut cloth tightly.

[0032] Through the combination of the linear slide rail 51 and the lifting member 52, the cutting machine 53 can move freely in the horizontal and vertical directions, so that the device can easily meet the cutting needs of glass fiber cloth of different widths and thicknesses, greatly improving the flexibility and adaptability of production.

[0033] The guide rollers 2 ensure the stability and flatness of the glass fiber cloth during transport, while the precise control of the lifting member 52 ensures a constant distance between the cutter 53 and the cloth. These factors work together to significantly improve cutting accuracy.

[0034] Since the device can automatically complete the entire process from unwinding to rewinding, with high cutting speed and high precision, it greatly improves production efficiency. At the same time, it reduces manual intervention and errors, and lowers production costs.

[0035] Specifically, the unwinder 3 in this embodiment includes a support seat 31 and an unwinding drum 32. The support seat 31 is set at one end of the support frame 1, and the unwinding drum 32 is rotatably set on the support seat 31.

[0036] The winder 4 includes a second support seat 41, a winding drum 42 and a driving member 43. The second support seat 41 is set at the other end of the support frame 1, and the winding drum 42 is rotatably set on the second support seat 41. The driving member 43 is connected to the winding drum 42 and is used to drive the winding drum 42 to rotate.

[0037] The support seat 1 31 is firmly arranged at one end of the support frame 1, providing solid support for the unwinding drum 32. The unwinding drum 32 is rotatably arranged on the support seat 1 31 and can rotate smoothly to release the glass fiber cloth.

[0038] The winder 4 consists of a second support base 41, a take-up drum 42, and a driver 43. The second support base 41 is located at the other end of the support frame 1, aligning with the unwinder 3 and providing stable support for the take-up drum 42. The take-up drum 42 is rotatably mounted on the second support base 41, ready to receive the fiberglass cloth cut by the slitting assembly 5. The driver 43 is tightly connected to the take-up drum 42, driving the take-up drum 42 to rotate, tightly winding the cut fiberglass cloth around it.

[0039] Specifically, the support seat 1 31 and the support seat 2 41 in this embodiment both include a fixed seat 311 relatively arranged at one end of the support frame 1, and two baffles 312 are relatively arranged on the fixed seat 311, and a screw rod 313 is rotatably arranged between the two baffles 312, and a rotating shaft seat 314 is threadedly connected to the screw rod 313, and a rotating shaft 315 is rotatably arranged on the rotating shaft seat 314, and a sleeve 316 is provided at one end of the rotating shaft 315, and the two ends of the winding drum 42 or the unwinding drum 32 are respectively inserted into the corresponding sleeve 316; a handwheel is provided at one end of the screw rod 313.

[0040] A threaded hole adapted to the screw rod 313 is defined inside the rotating shaft seat 314 .

[0041] Both the support base 1 31 and the support base 2 41 are designed with a fixing base 311 , and the fixing base 311 is firmly installed at one end of the support frame 1 .

[0042] Two baffles 312 are arranged opposite to each other on the fixing seat 311 , and a screw rod 313 is rotatably arranged between them.

[0043] The screw rod 313 is threadedly connected to the shaft seat 314 . This threaded connection design allows the shaft seat 314 to not only move along its axial direction on the screw rod 313 , but also adjust the position of the shaft seat 314 by rotating the screw rod 313 .

[0044] There is a threaded hole inside the shaft seat 314 that matches the thread of the screw rod 313, so that when the screw rod 313 rotates, the shaft seat 314 can move axially along the screw rod 313. The shaft seat 314 itself is fixed relative to the screw rod 313 and does not rotate with the screw rod 313.

[0045] A rotating shaft 315 is rotatably mounted on the rotating shaft seat 314. This design allows the rotating shaft 315 to rotate flexibly within the rotating shaft seat 314. A sleeve 316 is provided at one end of the rotating shaft 315. The two ends of the winding drum 42 or the unwinding drum 32 are respectively inserted into the corresponding sleeve 316, thereby achieving a stable installation and flexible rotation of the winding drum 42 or the unwinding drum 32 on the support seat.

[0046] The hand wheel can conveniently drive the screw rod 313 to rotate, thereby driving the shaft seat 314 to move axially along the screw rod 313, thereby adjusting the position of the sleeve 316 and clamping and fixing the winding drum 42 or the unwinding drum 32.

[0047] The driving member 43 in this embodiment includes a driving motor 431 arranged on the support frame 1, and the output shaft of the driving motor 431 and one end of the rotating shaft 315 are both provided with pulleys 432, and the two pulleys 432 are connected by belt transmission.

[0048] The driving motor 431 is fixed on the support frame 1 and is the power source of the driving member 43 .

[0049] When the output shaft of the driving motor 431 rotates, the pulley 432 thereon also rotates, and drives the pulley 432 connected to the winding drum 42 to rotate through the belt.

[0050] Since both ends of the take-up drum 42 are connected to each other by being inserted into the sleeve 316 , when the pulley 432 on the rotating shaft 315 rotates, the take-up drum 42 will also rotate accordingly.

[0051] In one embodiment, the linear guide rail 51 includes a housing 511 disposed on the support frame 1. A second drive motor 512 is disposed within the housing 511. The output shaft of the second drive motor 512 is provided with a threaded rod 513. The upper thread of the threaded rod 513 is threadedly connected to a transmission seat 514. The transmission seat 514 is provided with a threaded groove that is compatible with the threaded rod 513.

[0052] When the second drive motor 512 is started, its output shaft drives the threaded rod 513 to rotate. Due to the threaded connection between the transmission base 514 and the threaded rod 513, the transmission base 514 moves linearly along the axial direction of the threaded rod 513. This linear movement can accurately control the position of the component to be moved, achieving precise positioning and movement.

[0053] In one embodiment, the lifting member 52 includes two electric push rods relatively arranged at the bottom of the transmission base 514 . A through hole is opened at the bottom of the shell 511 . The piston rods of the electric push rods pass through the through hole and are connected to the cutting machine 53 .

[0054] In the lifting member 52, two electric push rods are respectively arranged on both sides of the bottom of the transmission base 514, standing opposite each other. When the electric push rods receive a control signal, the motor inside them starts to rotate and converts the rotational motion into linear reciprocating motion of the piston rod through the transmission mechanism.

[0055] The bottom of the housing 511 is provided with through holes, which allow the piston rod of the electric push rod to pass through and extend outside the housing 511. The extended end of the piston rod is connected to the cutter 53, so that when the piston rod performs linear reciprocating motion, the cutter 53 can be driven to move up and down in the vertical direction.

[0056] In this embodiment, the cutting machine 53 includes a mounting base slidably arranged at the bottom of the shell 511, and a reducer and a drive motor three are arranged on the mounting base. The output shaft of the reducer is provided with a rotating shaft two, and a cutting blade is provided on the rotating shaft two. The output shaft of the drive motor three is connected to the input shaft of the reducer.

[0057] When the fiberglass cloth needs to be cut, the electric push rod of the lifting member 52 first raises the cutter 53 to the appropriate height. Then, the control system adjusts the horizontal position of the mounting base so that the cutting blade is aligned with the fiberglass cloth to be cut. Next, the drive motor 3 is started, driving the shaft 2 and the cutting blade to rotate through the reducer. Finally, the control system controls the electric push rod of the lifting member 52 to slowly descend, so that the cutting blade contacts and cuts the fiberglass cloth.
