Description

Unwinding device

[0001] This disclosure claims priority to a Chinese patent application filed with the Patent Office of China on November 28, 2023, with application number 202323238315.3 and application name “Unwinding Device,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to an unwinding device. Background Art

[0003] In related technologies, unwinding devices typically utilize a material tray, spring, and expansion block to form the unwinding mounting portion. This expands the inner wall of the coil, and the unwinding mounting portion rotates under external power to unwind. While the material tray is connected to the device's mounting plate, an elastic member allows for floating movement between the tray's end and the mounting plate to compensate for the necessary positional adjustments during unwinding.

[0004] However, since the elastic member is a non-rigid structure, it is easy for the elastic member to shake in the axial direction when the unwinding mounting portion rotates. The material roll is prone to axial movement after being subjected to the power, which affects the glue application accuracy and easily causes the material roll to fall off the unwinding mounting portion.

[0039] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] The unwinding device 100 according to an embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0041] As shown in FIG. 1 to FIG. 6 , the unwinding device 100 according to an embodiment of the present disclosure includes: a mounting plate 10 , a driving member 20 , an unwinding shaft 30 and an unwinding disc 40 .

[0042] Specifically, the driving member 20 is arranged on the first side of the mounting plate 10, and the driving member 20 has a driving shaft 21. The driving shaft 21 passes through the mounting plate 10 and extends to the second side of the mounting plate 10. The driving shaft 21 is rotatable around its own axis. The unwinding shaft 30 is arranged on the second side of the mounting plate 10. The first end of the unwinding shaft 30 is connected to the driving shaft 21 and moves synchronously with the driving shaft 21. The second end of the unwinding shaft 30 is away from the mounting plate 10. A limiting surface 51 is provided on the outer surface of the unwinding shaft 30. The limiting surface 51 forms an inclined surface extending obliquely relative to the axis of the unwinding shaft 30, and the limiting surface 51 gradually moves away from the axis of the unwinding shaft 30 from the first end of the unwinding shaft 30 to the second end. The unwinding disk 40 is arranged at the first end of the unwinding shaft 30 and is fixedly connected to the unwinding shaft 30.

[0043] In other words, the unwinding device 100 according to the embodiment of the present disclosure can be mainly composed of a mounting plate 10, a driving member 20, an unwinding shaft 30 and an unwinding disk 40, wherein the mounting plate 10 can constitute the supporting structure of the unwinding device 100, the driving member 20, the unwinding shaft 30 and the unwinding disk 40 can all be arranged on the mounting plate 10, the driving member 20 can be a tensioner driving member 20, the fixing part of the driving member 20 can be fixedly arranged on one side of the mounting plate 10, and the driving shaft 21 of the driving member 20 passes through the mounting plate 10 and extends to the other side of the mounting plate 10. The unwinding shaft 30 is arranged on the other side of the mounting plate 10 and is fixedly connected to the drive shaft 21. The unwinding disk 40 is arranged at one end of the unwinding shaft 30 close to the mounting plate 10. The unwinding disk 40 can be fixedly connected to the unwinding shaft 30 through a connecting piece and move with it. The unwinding shaft 30 and the unwinding disk 40 can be used to install the material roll, so that the material roll, the unwinding disk 40 and the unwinding shaft 30 can rotate synchronously under the drive of the drive shaft 21.

[0044] Among them, the outer surface of the unwinding shaft 30 is provided with a limiting surface 51, and the limiting surface 51 can be a complete inclined surface, that is, an annular inclined surface designed around the outer surface of the unwinding shaft 30, or a inclined surface formed by multiple relatively independent inclined surfaces. Regardless of whether the limiting surface 51 is a complete inclined surface or an inclined surface composed of multiple inclined surfaces, the structural design of the limiting surface 51 makes the limiting surface 51 gradually increase in the direction away from the mounting plate 10, so that a micro-angle is formed between the limiting surface 51 and the inner side wall of the material roll. This structure can apply a supporting force to the material roll, and the direction of action of the supporting force is perpendicular to the plane where the limiting surface 51 is located. By decomposing the supporting force, part of the force applies radial force to the material roll, and part of the force applies axial force to the material roll, so that the limiting member can effectively prevent the material roll from moving in the axial direction of the unwinding shaft 30 and falling out.

[0045] It should also be noted that the driving member 20 may be a magnetic damper, and the structural design of the driving member 20 enables it to drive the unwinding shaft 30, the unwinding disk 40 and the material roll to rotate synchronously around its own axis.

[0046] Therefore, according to the unwinding device 100 of the embodiment of the present disclosure, by setting a limiting surface 51 on the outer surface of the unwinding shaft 30, the limiting surface 51 can limit the material roll assembled on the unwinding shaft 30, thereby effectively improving the stability and adjustment range of the unwinding device 100, thereby reducing the movement of the material roll and ensuring the gluing accuracy of the material roll.

[0047] According to one embodiment of the present disclosure, the unwinding shaft 30 is provided with a mounting channel extending through the unwinding shaft 30 along its axial direction, and one end of the driving shaft 21 passes through the mounting channel and is fixedly connected to the unwinding shaft 30 .

[0048] Specifically, as shown in FIG2 , in this embodiment, a channel is provided in the center of the unwinding shaft 30, which is provided with a channel extending therethrough in the axial direction. The structure of the channel is adapted to the structure of the drive shaft 21, so that the drive shaft 21 can pass through the unwinding shaft 30 and be fixedly connected to the unwinding shaft 30. The specific connection method can be to use a bolt 31 and a washer to achieve axial fixation of the unwinding shaft 30 and the drive shaft 21. This assembly method is simple in structure, easy to assemble, and has a high stability of the rigid connection structure.

[0049] Optionally, in some specific embodiments of the present disclosure, the unwinding device 100 further includes: a plurality of limiting members 50, which are arranged at intervals along the circumference of the unwinding shaft 30 on the outer peripheral surface of the unwinding shaft 30, the first end of the limiting member 50 is close to the mounting plate 10, and the second end of the limiting member 50 is away from the mounting plate 10, and the outer surface of each limiting member 50 is respectively provided with a limiting surface 51.

[0050] Specifically, as shown in Figures 1 and 3, the unwinding shaft 30 is formed into a cylindrical structure. A plurality of stoppers 50 are provided on the outer circumference of the unwinding shaft 30. Each stopper 50 extends along the axial direction of the unwinding shaft 30, and the plurality of stoppers 50 are spaced apart along the circumference of the unwinding shaft 30. The outer surface of each stopper 50 has a stopper surface 51 formed into an inclined structure. The structural design of the stopper surface 51 causes the outer circumference of the plurality of stopper surfaces 51 to gradually increase in the direction away from the mounting plate 10. The design of the stopper surface 51 forms a slight angle between the stopper 50 and the inner sidewall of the roll. This structure can apply a supporting force to the roll, and the direction of the supporting force is perpendicular to the plane where the stopper surface 51 is located. By decomposing the supporting force, part of the force applies a radial force to the roll, and part of the force applies an axial force to the roll, so that the stopper can effectively prevent the roll from moving in the axial direction of the unwinding shaft 30 and falling out.

[0051] Therefore, by arranging multiple limit members 50 on the unwinding shaft 30, the limit members 50 can be tension bars, which can effectively enhance the limiting effect of the unwinding shaft 30 on the material roll, thereby avoiding the possibility of the material roll moving in the axial direction of the unwinding shaft 30 and falling out, and effectively improving the stability of the unwinding device 100.

[0052] According to some embodiments of the present disclosure, the outer peripheral surface of the unwinding shaft 30 is provided with a plurality of mounting grooves 32 spaced apart along its circumference, each mounting groove 32 extends along the axial direction of the unwinding shaft 30 , and each limiting member 50 is respectively arranged in the corresponding mounting groove 32 .

[0053] As shown in FIG2 , in this embodiment, the position-limiting member 50 can be mounted on the unwinding shaft 30 through the mounting grooves 32 provided on the outer surface of the unwinding shaft 30. The shape of each mounting groove 32 can correspond to the shape of the position-limiting member 50. The mounting grooves 32 can be sliding grooves, and the position-limiting member 50 can be slidably inserted into the unwinding shaft 30 through the mounting grooves 32. Thus, by providing the mounting grooves 32 on the outer surface of the unwinding shaft 30, the assembly of the position-limiting member 50 on the unwinding shaft 30 can be facilitated.

[0054] Optionally, according to one embodiment of the present disclosure, a mounting hole 52 is provided on one side surface of each limiting member 50 close to the unwinding shaft 30, and the unwinding device 100 also includes: an elastic member 60, the elastic member 60 is provided in the mounting hole 52, the first end of the elastic member 60 abuts the bottom wall of the mounting hole 52, and the second end of the elastic member 60 abuts the bottom wall of the mounting groove 32.

[0055] Specifically, as shown in Figure 2, each limiting member 50 can be provided with a mounting hole 52, the opening of the mounting hole 52 is opposite to the bottom wall of the mounting groove 32, and an elastic member 60 is provided in the mounting hole 52. The elastic member 60 can be a spring structure, and the elastic member 60 is squeezed between the bottom wall of the mounting hole 52 and the bottom wall of the mounting groove 32.

[0056] Therefore, by arranging the elastic member 60 structure between the limiting member 50 and the mounting groove 32 of the unwinding shaft 30, the elastic member 60 can make the position of the limiting member 50 have a certain adjustment range, so as to better assemble it with the material roll.

[0057] In some specific embodiments of the present disclosure, each limiting member 50 is provided with a plurality of mounting holes 52 , which are spaced apart along the axial direction of the unwinding shaft 30 , and an elastic member 60 is provided in each mounting hole 52 .

[0058] That is to say, as shown in Figure 2, each limiting member 50 can be provided with multiple mounting holes 52 structures, for example, there can be two, three or more, and the multiple mounting holes 52 can be evenly distributed in the axial direction of the limiting member 50. An elastic member 60 can be respectively provided in each mounting hole 52, thereby further improving the assembly and limiting effect of the limiting member 50 on the material roll.

[0059] Optionally, according to some embodiments of the present disclosure, the cross section of the mounting groove 32 is formed in a T-shape. Furthermore, the end of the mounting groove 32 away from the mounting plate 10 is closed, and the end of the mounting groove 32 close to the mounting plate 10 is open.

[0060] In other words, in the axial direction of the unwinding shaft 30, the mounting groove 32 is formed as a long groove that is open at one end toward the mounting plate 10 and closed at one end away from the mounting plate 10, and the cross-section of the mounting groove 32 can be formed as a T-shaped structure, and the limit member 50 is formed as a structure corresponding to the shape of the mounting groove 32. The limit member 50 can be slidably inserted into the mounting groove 32 from the open end of the mounting groove 32, and after the insertion is completed, one end stops at the unwinding reel 40, thereby effectively ensuring the assembly stability of the limit member 50 in the mounting groove 32 and preventing the limit member 50 from falling out of the mounting groove 32.

[0061] According to some embodiments of the present disclosure, the unwinding device 100 further includes a sensor 70 , which is disposed on the mounting plate 10 and is used to detect the remaining amount of the material roll on the unwinding disk 40 .

[0062] Specifically, as shown in Figure 4, the number of sensors 70 can be adjusted according to actual needs. The sensors 70 are arranged on the mounting plate 10 and correspond to the position of the unwinding disk 40. The sensors 70 can be used to detect the remaining amount of the material roll on the unwinding disk 40, thereby reminding the user to replenish the material in time.

[0063] In other specific embodiments of the present disclosure, the unwinding device 100 further includes: a fixing rod 80 and a clamping block 90, wherein one end of the fixing rod 80 is connected to the mounting plate 10, and the clamping block 90 is suitable for being fixedly connected to the part to be mounted, and the clamping block 90 is movable to clamp or release the fixing rod 80.

[0064] As shown in Figures 5 and 6, the fixing rod 80 and the clamping block 90 constitute a rigid fixing mechanism of the unwinding device 100. The clamping block 90 can be used to fix to the external equipment connecting plate, thereby realizing the rigid fixation of the unwinding device 100. The fixing rod 80 can be movably set on the clamping block 90. ​​After the clamping block 90 releases the fixation of the fixing rod 80, the fixing rod 80 can be slid to adjust the overall position of the unwinding device 100 on the clamping block 90, thereby realizing the rigid compensation of the position of the material roll by the unwinding device 100, avoiding the shaking caused by the floating adjustment of the material roll by using elastic parts, further improving the stability and adjustment range of the unwinding device 100, thereby reducing the movement of the material roll and ensuring the gluing accuracy of the material roll.

[0065] According to some embodiments of the present disclosure, two adjustment holes 91 are provided on the clamping block 90 at intervals, and there are two fixing rods 80, each fixing rod 80 is respectively passed through the corresponding adjustment hole 91, and the opening size of the adjustment hole 91 can be adjusted to clamp or loosen the fixing rod 80.

[0066] Specifically, as shown in Figures 5 and 6, adjustment holes 91 are respectively provided at the left and right ends of the clamping block 90. ​​Each adjustment hole 91 can be formed as an open hole structure with one end open. By clamping or loosening the two ends of the clamping block 90, the aperture size of the adjustment hole 91 can be adjusted, thereby clamping or loosening the fixing rod 80 in the adjustment hole 91 to achieve the effect of rigidly adjusting the position of the fixing rod 80.
