Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber textile cloth production, and particularly relates to a winding device for glass fiber textile cloth. Background Art

[0002] The winding of glass fiber textile cloth is an important link in the production process of glass fiber cloth. However, the existing winding device winds by passing a mandrel through a winding roller and then driving the mandrel to rotate through a motor, and then driving the winding roller to directly wind. This winding method has the following problems: 1. The mandrel is subjected to high stress, so the manufacturing cost is relatively high; 2. As the winding diameter of the winding roller becomes larger and larger, when the mandrel rotates one week, the traction distance becomes longer, resulting in an increasing traction force. Although the glass fiber textile cloth is tightened to a certain extent, due to the excessive traction force, the glass fiber cloth is also pulled and deformed, thus affecting the product quality. Content of the Utility Model

[0003] The purpose of the utility model is to provide a winding device for glass fiber textile cloth, which can not only reduce the stress on the mandrel, thereby reducing the manufacturing cost, but also provide a stable traction force and will not cause pulling and deformation of the glass fiber cloth.

[0004] In order to achieve the above purpose, the utility model provides a winding device for glass fiber textile cloth, which comprises a frame and a winding device and a tensioning device arranged on the frame; the frame comprises a left frame and a right frame which are oppositely arranged left and right; the winding device comprises a driving roller and a driven roller rotatably installed between the left frame and the right frame and a driving motor fixed on the frame and driving the driving roller and the driven roller to rotate; the driving roller and the driven roller are arranged side by side at intervals and the rotation directions of the two are the same; a winding roller for winding the glass fiber textile cloth is supported on the driving roller and the driven roller; the tensioning device is arranged at the bottom of the winding device; the glass fiber textile cloth first passes through the tensioning device to be tensioned and then penetrates upward through the gap between the driving roller and the driven roller and is clamped between the driving roller and the winding roller and then wound upward onto the winding roller.

[0005] After adopting the above structure, the winding roller is directly supported above the driving roller and the driven roller, thereby reducing the stress on the mandrel and reducing the manufacturing cost of the mandrel; the winding roller is frictionally rotated through friction, so as to realize winding, and the traction force of the glass fiber textile cloth will not be affected due to the increase of the diameter of the winding roller, so that the traction force is always kept stable, and the problem of pulling and deformation of the glass fiber cloth is avoided.

[0006] In order to keep a certain tensioning force on the glass fiber textile fabric during the winding process, the tensioning device includes a tensioning roller arranged between the left frame and the right frame, and a swinging device is arranged between the two ends of the tensioning roller and the left frame and the right frame; the swinging device includes a connecting rod rotatably installed on the left frame or the right frame in the middle, the tensioning roller is rotatably installed on the upper part of the connecting rod, and an elastic component is arranged between the lower part of the connecting rod and the frame.

[0007] In order to conveniently adjust the tensioning force, the elastic component includes a reset spring and an adjusting device connected to each other. The adjusting device includes an adjusting cylinder and an adjusting screw screwed in the adjusting cylinder. The adjusting screw is connected to the reset spring.

[0008] In order to prevent the reset spring from twisting when adjusting the tension, a rotating drum is rotatably installed in the central channel of the adjusting drum, and a threaded hole is arranged at the central axis position of the rotating drum; an adjusting screw rod is screwed in the threaded hole.

[0009] In order to avoid axial movement of the rotating drum, a through hole is opened on the side wall of the adjusting cylinder, which connects the outside with the central channel; a limiting column is fixed in the through hole, and the limiting column extends into the central channel; an annular groove is opened on the outer wall of the rotating drum corresponding to the limiting column, and when the limiting column extends into the central channel, it is inserted into the annular groove and slides along the annular groove.

[0010] In order to facilitate the application of force when rotating the drum, a turntable is arranged above the drum, and the outer peripheral surface of the turntable is provided with anti-slip grooves.

[0011] In order to reduce the investment cost of the driving motor, the active roller and the driven roller are transmission-connected to the same driving motor.

[0012] In order to limit the winding roller, limit rods are installed on both sides of the winding roller on the frame. The limit rods extend downward to the top of the gap between the active roller and the driven roller and do not contact the active roller and the driven roller; the winding roller is limited between the limit rods on both sides.

Detailed Embodiments

[0022] The present utility model will be further described below with reference to the accompanying drawings.

[0023] All orientations mentioned in this specification are based on the orientation when a winding device for a glass fiber textile fabric of the present utility model is working properly, without limiting its orientation during storage and transportation, and only representing relative positional relationships, not absolute positional relationships.

[0024] Embodiment 1:

[0025] As Figure 1 and Figure 2 collectively show, a winding device for a glass fiber textile fabric includes a frame 1 and a winding device and a tensioning device 7 provided on the frame 1.

[0026] The frame 1 includes a left frame 11 and a right frame 12 that are oppositely arranged left and right; the winding device includes a driving roller 2 and a driven roller 3 that are rotatably installed between the left frame 11 and the right frame 12 and a driving motor 4 that is fixed on the frame 1 and drives the driving roller 2 and the driven roller 3 to rotate; the driving roller 2 and the driven roller 3 are arranged side by side at intervals and rotate in the same direction. In this embodiment, both the driving roller 2 and the driven roller 3 rotate Figure 2 clockwise as shown in; a winding roller 5 for winding the glass fiber textile fabric 6 is supported on the driving roller 2 and the driven roller 3, and the winding roller 5 is pressed above the driving roller 2 and the driven roller 3 under the action of gravity, and under the action of friction, the winding roller 5 rotates and its rotation direction is opposite to that of the driving roller 2 and the driven roller 3, that is, Figure 2The glass fiber woven fabric 6 penetrates upward from the gap between the active roller 2 and the driven roller 3 and is clamped between the active roller 2 and the winding roller 5.

[0027] The tensioning device 7 is arranged at the bottom of the winding device. The glass fiber woven cloth 6 is first tensioned by the tensioning device 7 and then enters the winding device for winding.

[0028] In order to reduce the input amount of the driving motor 4, the active roller 2 and the driven roller 3 are connected to the same driving motor 4. That is, a driving wheel is fixedly installed on one side of the roller shaft of the active roller 2, and a driven wheel is fixedly installed on one side of the roller shaft of the driven roller 3. The active wheel and the driven wheel are connected by a belt or chain transmission. The driving motor 4 is fixedly connected to the roller shaft of the active roller 2, so that the active roller 2 and the driven roller 3 are connected to the same driving motor 4, and the active roller 2 and the driven roller 3 are driven to rotate in the same direction by the same driving motor 4.

[0029] In this embodiment, the specifications of the driving wheel and the driven wheel are consistent, so the rotation speeds of the driving roller 2 and the driven roller 3 are consistent; in practical applications, the number of teeth of the driving wheel and the driven wheel can be fine-tuned to make a certain speed difference between the driving roller 2 and the driven roller 3, thereby achieving a tightening effect.

[0030] The surface of the driven roller 3 is provided with an uneven pattern to avoid slipping and the problem of loose winding.

[0031] In order to prevent the winding roller 5 from shaking in the left and right directions during the rotation process, limit rods 8 are installed on both sides of the winding roller 5 on the frame 1. The limit rods 8 extend downward to the top of the gap between the active roller 2 and the driven roller 3 and do not contact the active roller 2 and the driven roller 3. The winding roller 5 is limited between the limit rods 8 on both sides. The limit rods 8 limit the winding roller 5 to the left and right, thereby preventing it from shaking to the left and right.

[0032] Furthermore, in order to adapt to the length of the winding roller 5 of different specifications, the two limit rods 8 are installed on the frame 1 with adjustable distance. The specific structure is: the left frame 11 and the right frame 12 are fixedly connected by two cross braces 13, and the active roller 2 and the driven roller 3 are located between the two cross braces 13. The limit rod 8 is fixed to the cross brace 13 through a bracket, and is detachably fixed to the cross brace 13 through a hanging steel 14. When the position of the bracket needs to be adjusted, the hanging steel 14 can be disassembled.

[0033] In this winding method, the winding roller 5 is directly supported above the active roller 2 and the driven roller 3, thereby avoiding the problems of high force strength on the core shaft and high cost. The winding roller 5 is rotated by friction through friction force to achieve winding. The traction force of the glass fiber textile cloth 6 is not affected by the increase in the diameter of the winding roller 5. The traction force always remains stable, thereby avoiding the problem of pulling and deformation of the glass fiber textile cloth 6.

[0034] Embodiment 2:

[0035] The tensioning device 7 includes a tensioning roller 71 disposed between the left frame 11 and the right frame 12. Swing devices are provided between the two ends of the tensioning roller 71 and the left frame 11 and the right frame 12. The swing device includes a connecting rod 72 rotatably mounted in the middle on the left frame 11 or the right frame 12. The upper part of the connecting rod 72 is rotatably mounted with the tensioning roller 71, and an elastic component 73 is provided between its lower part and the frame. The elastic component 73 can be a spring or a pneumatic spring, etc.

[0036] When the tensioning roller 71 is tensioned, it rotates around the hinge point of the connecting rod 72, and the elastic component 73 provides a certain tensioning force to keep it stable.

[0037] As Figure 3 and Figure 4 collectively shown, in this embodiment, in order to reduce production costs and at the same time increase the adjustability of the elastic force of the elastic component 73, the elastic component 73 includes a return spring 731 and an adjusting device connected to each other. The adjusting device includes an adjusting cylinder 732 and an adjusting screw rod 733 screwed into the adjusting cylinder 732.

[0038] By rotating the adjusting screw rod 733, the length of the adjusting screw rod 733 screwed into the adjusting cylinder 732 is controlled, so as to adjust the spring force of the return spring 731 and realize the adjustability of the tensioning force.

[0039] As an improvement of this embodiment, because when the adjusting screw rod 733 is rotated, the return spring 731 needs to be disassembled, otherwise it will drive the return spring 731 to generate a certain twist due to rotation, and disassembling the return spring 731 is very cumbersome. To avoid this problem, the following improvements are made in this embodiment.

[0040] A rotating cylinder 734 is rotatably mounted in the central channel of the adjusting cylinder 732. A threaded hole is provided at the central axis position of the rotating cylinder 734. The adjusting screw rod 733 is screwed into the threaded hole. When it is necessary to adjust the length of the adjusting screw rod 733 extending into the adjusting cylinder 732, one hand holds the adjusting screw rod 733 tightly, and the other hand rotates the rotating cylinder 734. Under the action of the thread, the adjusting screw rod 733 extends into or withdraws from the adjusting cylinder 732.

[0041] To prevent the rotating cylinder 734 from axially moving, through holes are opened on the side wall of the adjusting cylinder 732. The through holes communicate the outside with the central channel. A limiting post 735 is fixed in the through holes. The limiting post 735 extends into the central channel. An annular groove is provided on the outer side wall of the rotating cylinder 734 corresponding to the limiting post 735. After the limiting post 735 extends into the central channel, its inner end is inserted into the annular groove and slides along the annular groove.

[0042] Above the rotary cylinder 734, there is a turntable, and anti-slip patterns are provided on the outer peripheral surface of the turntable.

[0043] With this structure, when it is necessary to adjust the length of the adjusting screw rod 733 inserted into the adjusting cylinder 732, rotate the rotary cylinder 734, and the adjusting screw rod 733 can enter or exit the adjusting cylinder 732 without rotating, thus avoiding the rotation of the adjusting screw rod 733 and causing the torsion of the return spring 731.

[0044] Certainly, the above description is not a limitation on the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
