Technical Field

[0001] The utility model belongs to the technical field of glass fiber cloth processing, and particularly relates to a glass fiber cloth unwinding device. Background Art

[0002] Glass fiber cloth needs to go through an appearance quality inspection process before leaving the factory. During the manual inspection process, the glass fiber cloth to be inspected usually needs to be unwound using an unwinding device first. The inspector performs an appearance quality inspection on the unwound glass fiber cloth, and then uses a rewinding device to rewind the inspected finished glass fiber cloth. The unwinding roller of the existing unwinding device is fixed and parallel to the rewinding roller of the finished glass fiber cloth. Sometimes, due to the unbalanced tension on both sides of the different glass fiber cloth rolls to be inspected, the unwinding process may deviate, thereby affecting the subsequent rewinding of the finished glass fiber cloth. Therefore, there is an urgent need to improve the existing unwinding device structure and provide a method for adjusting the cloth delivery direction of the unwinding roller to solve the problem of deviation of the glass fiber cloth to be inspected during the unwinding process and ensure the normal rewinding of the finished glass fiber cloth.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0022] like Figure 1As shown, a glass fiber cloth unwinding device includes an unwinding roller 1, a first bearing seat 2, a second bearing seat 3, a first column 4 and a second column 5. The two ends of the unwinding roller are rotatably connected to the first bearing seat and the second bearing seat respectively. The first bearing seat is hinged to the top of the first column, and the second bearing seat is slidably connected to the top of the second column. The second column is provided with an adjustment mechanism for adjusting the position of the second bearing seat. Wing plates 20 are provided on both sides of the bottom ends of the first column and the second column, and reinforcing ribs 21 are connected between the corresponding wing plates to ensure the supporting strength and stability of the first column and the second column. A motor 6 is provided on one side of the first bearing seat, and the output shaft of the motor is connected to the unwinding roller through a universal coupling 7. The motor provides power. The universal coupling can ensure that the unwinding roller and the output shaft can be driven to rotate even if they are not on the same central axis, thereby realizing the unwinding of the glass fiber cloth. During the unwinding process of the glass fiber cloth, if the glass fiber cloth deviates, the unwinding roller is driven to swing and the outgoing direction of the glass fiber cloth is adjusted to correct the deviation and facilitate the rewinding of the finished glass fiber cloth after inspection.

[0023] Combine Figure 2 As shown, the adjustment mechanism includes a sleeve 8, a screw 9, an adjusting disk 10 and a slide 11. The second bearing seat is slidably connected to the slide provided on the second column, and its lower end is connected to the sleeve. The sleeve is threadedly connected to the screw, and the screw is rotatably connected to the second column, and one end is connected to the adjusting disk. The operator rotates the adjusting disk to drive the screw to rotate, thereby driving the second bearing seat to slide along the slide, realizing the swing of the unwinding roller and changing the cloth output direction.

[0024] In order to realize the quick disassembly and assembly of the unwinding roller, Figure 1 and Figure 3 As shown, the first bearing seat and the second bearing seat are both rotatably connected with a positioning shaft, and the two positioning shafts are detachably connected to the two ends of the unwinding roller. The positioning shaft includes a shaft head 12, a telescopic component and a positioning sleeve 13. One end of the shaft head is rotatably connected to the first bearing seat or the second bearing seat, and the other end is connected to the telescopic component. The telescopic component is connected to the positioning sleeve. Each end of the unwinding roller is connected with a protrusion 23. The protrusion is inserted into the positioning sleeve and assembled and connected by a bolt 14. The position of the positioning sleeve is adjusted by the telescopic component so that the protrusion can be quickly inserted into the positioning sleeve to achieve positioning and locking. The telescopic component includes a fixed plate 15, a movable plate 16, a guide rod 17, a spring 18 and a limit nut 19. One end of the guide rod is vertically connected to one side of the fixed plate, and the other end passes through the movable plate and is connected to the limit nut. The movable plate is slidably connected to the guide rod. The spring sleeve is set on the guide rod and is located between the fixed plate and the movable plate. The positioning sleeve is connected to the movable plate.

[0025] The working principle of this utility model is as follows:

[0026] like Figures 1 to 3As shown, during operation, the motor 6 drives the unwinding roller 1 to rotate and unwind the glass fiber cloth. If the glass fiber cloth deviates during the unwinding process, the adjusting disk 10 can be manually rotated to drive the screw 9 to rotate, thereby changing the cloth delivery direction of the unwinding roller 1 to adjust it in the opposite direction of the deviation. After the glass fiber cloth is unwound, the bolt 14 is first removed, and then the movable plate 16 is pressed toward the fixed plate 15. The protrusion 23 at the end of the unwinding roller is removed from the positioning sleeve 13 to complete the unwinding roller 1 removal.

[0027] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
