Description

Technical Field

[0001] This utility model relates to the field of glass fiber cloth production technology, and in particular to an unwinding mechanism for a glass fiber cloth transverse splicing machine. Background Technology

[0002] Fiberglass cloth is one of the main raw materials for fiberglass boards. Before making fiberglass boards, a large roll of fiberglass cloth needs to be unwound, and then both sides of the cloth are cut to ensure the remaining width matches the fiberglass board width. Because fiberglass cloth is relatively expensive, the industry generally recycles the cut strips. One method is to overlap two or more of the cut strips in the width direction (transverse direction), and then use adhesive or hot-melt bonding to join the overlaps, making the width meet the requirements for fiberglass board production. Due to the seams, this method is generally used to make lower-grade fiberglass boards.

[0003] In practice, it was found that because the width of the edge strips is not uniform, and the existing edge strip unwinding uses a general-purpose unwinding machine, workers often need to adjust the placement of the two edge strip unwinding machines to ensure that one edge strip can be smoothly overlapped with the other edge strip. This is quite troublesome to operate and the problem remains to be solved. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings in the above-mentioned background technology and provide an unwinding mechanism for a transverse splicing machine for fiberglass cloth, which can overlap two rolls of edge strips and easily adjust the position of the edge strips.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A fiberglass cloth transverse splicing machine has an unwinding mechanism, comprising a first unwinder and a second unwinder. The bases of the two unwinders are respectively mounted on the fabric feeding side of the splicing machine frame via guide rails and sliders. The guide rails are arranged horizontally in the transverse direction. The unwinding shafts of the two unwinders are staggered vertically, and the distance between one unwinding shaft and the frame is greater than that between the other unwinding shaft and the frame. Each unwinding shaft has a support arm at only one end, with the other end extending outwards, and the extension directions of the unwinding shafts of the two unwinders are opposite.

[0007] In a further embodiment, guide rollers are provided at the upper ends of both the fabric inlet and outlet sides of the frame, with the highest point of the guide rollers extending a certain distance beyond the top surface of the splicing machine.

[0008] In a further embodiment, the slider or base is provided with a locking mechanism for locking the position.

[0009] The beneficial effects of this utility model are as follows: This utility model installs two unwinding machines on the side of the splicing machine frame, staggered vertically and both of which can slide laterally. After the worker installs the edge strip roll onto the unwinding shaft, the unwinding machine can be easily adjusted in the lateral position using the guide rail and slider. The staggered vertical position and the overhanging structure of the unwinding shaft can prevent interference between the edge strip and the unwinding machine support arm, allowing the two edge strips to overlap smoothly, making the operation more convenient. Attached Figure Description

[0010] Figure 1 This is a structural schematic diagram (top view) of an embodiment of the present invention.

[0011] Figure 2 This is a schematic diagram (front view) of the structure of this utility model installed on the splicing machine.

[0012] The diagram includes: frame 1, first unwinding machine 2, second unwinding machine 3, base 4, guide rail 5, slider 6, fiberglass cloth 7, first edge strip 7.1, second edge strip 7.2, and welding mechanism 8. Detailed Implementation

[0013] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but the present utility model is not limited to the following embodiments.

[0014] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] like Figure 1 , Figure 2 As shown, the unwinding mechanism of a fiberglass cloth transverse splicing machine provided in this embodiment includes a first unwinding machine 2 and a second unwinding machine 3. The bases 4 of the two unwinding machines are respectively installed on the cloth feeding side of the frame 1 of the splicing machine via guide rails 5 and sliders 6. The guide rails 5 are arranged horizontally in the transverse direction. The sliders 6 or the bases 4 are provided with locking mechanisms for locking the position.

[0016] To ensure that the edge of one edge strip covers the edge of another, this implementation involves offsetting the two unwinding machines vertically by a certain height, with the first unwinding machine 2 below and the second unwinding machine 3 above. This also offsets the two unwinding shafts vertically, with the unwinding shaft of the first unwinding machine 2 closer to the frame 1 and the unwinding shaft of the second unwinding machine 3 relatively further away. This prevents the unwinding of the edge strip roll from being obstructed by an excessively large edge strip roll diameter. Each unwinding shaft has a support arm at only one end, with the other end extending outwards. The unwinding shafts of the two unwinding machines extend in opposite directions: the unwinding shaft of the first unwinding machine 2 extends towards the second unwinding machine 3, and the unwinding shaft of the second unwinding machine 3 extends towards the first unwinding machine 2.

[0017] like Figure 2 As shown, in order to smoothly guide the edge strip into the welding mechanism 8 at the top of the frame 1 and to avoid friction between the edge strip and the top of the frame 1, guide rollers are provided at the upper ends of both the fabric inlet side and the fabric outlet side of the frame 1. The highest point of the guide rollers extends a certain distance beyond the top surface of the splicing machine.

[0018] The first side strip 7.1 is unwound from the first unwinding machine 2, and the second side strip 7.2 is unwound from the second unwinding machine 3. At the guide roller, a part of the second side strip 7.2 overlaps the top surface of the first side strip 7.1, and then they enter the welding mechanism 8 together and are connected together. After passing through another guide roller, they are wound up on the winding mechanism on the fabric output side of the frame 1.

[0019] The above description is merely a preferred embodiment of this utility model. For those skilled in the art, various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
