The automatic tape wrapping machine includes a tape wrapping head, and the insulation tape reel is installed on the tape wrapping head. The tape wrapping head moves along the metal coil and rotates to wrap the insulation tape on the reel around the metal coil.

[0003] In the prior art, the tape reel is usually connected to the rotating shaft of the tape wrapping head by a snap-on spring. In the production workshop, the operators of the tape wrapping machine are usually female workers. When replacing the tape reel, the female workers need to pinch the snap-on with their fingers to tighten the snap-on to take out the tape reel. The female workers have little strength and it is inconvenient to use, which affects the work efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a tape reel installation structure and a tape wrapping head. The tape reel installation structure can not only easily and firmly connect the tape reel and the tape wrapping head rotating shaft, but also easily take out the tape reel.

[0005] A tape wrapping head with a simple installation structure comprises a bottom plate, a rotating assembly mounted on the bottom plate, a cover plate and a mounting structure, wherein the rotating assembly comprises a rotating shaft, a bearing and a mounting seat, the tape reel is mounted on the rotating shaft, and the mounting structure connects the cover plate with the mounting seat; the mounting structure comprises a movable part and a fixed part; the movable part is connected to the cover plate, and the fixed part is connected to the mounting seat; a through hole is opened at the center of the cover plate, the movable part comprises a shaft sleeve 1 and a pressure rod, the shaft sleeve 1 movably passes through the through hole at the center of the cover plate, and the pressure rod movably penetrates into the center hole of the shaft sleeve 1; a groove is opened on the inner wall of the center hole of the shaft sleeve 1;

[0006] The fixed part includes a reducing shaft, a second sleeve and a spring. The reducing shaft is fixed to the mounting seat, one end of the second sleeve is movably connected to the reducing shaft, and the other end is movably inserted into the center hole of the first sleeve. From the cover plate to the reel, the pressure rod and the second sleeve are sequentially arranged in the center hole of the first sleeve; the spring is installed at one end of the second sleeve close to the mounting seat; at least one through hole is opened on the outer diameter of the second sleeve, and a ball matched with the groove is arranged in the through hole; the reducing shaft is provided with a reduced diameter part, and the diameter of the reduced diameter part is smaller than the diameter of other parts of the reducing shaft, so that there is a gap between the reduced diameter part and the inner wall of the center hole of the second sleeve; when the second sleeve is pushed to move toward the mounting seat, the spring is compressed, and when the ball reaches the reduced diameter part, the ball is squeezed, and the ball shrinks into the through hole and enters the gap.

[0007] Furthermore, it also includes a second spring, the first shaft sleeve is T-shaped, the second spring is sleeved on the thinner part of the first T-shaped shaft sleeve, and the second spring is located between the first shaft sleeve and the inner wall of the central through hole of the cover plate.

[0008] During installation, the sleeve is placed on the sleeve 2, and the sleeve 1 moves vertically downward, and the ball is stuck in the groove. Due to the cooperation of the ball and the groove, and there is no space between the sleeve 2 and the reducer shaft for the ball to extend into, the sleeve 1 drives the sleeve 2 to move downward. During the movement, the reducer shaft is always stationary. When the ball moves to the sleeve 2 to the position where the diameter of the reducer shaft is smaller (the reduced diameter part), the downward force of the sleeve 1 and the ball presses the ball into the gap, and then the sleeve 1 can be easily inserted until the cover plate contacts the reel and the downward pressure operation is stopped; after the hand is released, the spring 2 rebounds to push the sleeve 1 in the opposite direction, and the spring 1 rebounds to push the sleeve 2 in the opposite direction, and the ball re-extends into the groove to complete the installation. The utility model can be applied to reels of different thicknesses, and the stop position of the cover plate is determined by the thickness of the reel.

[0009] During disassembly, press the pressure rod downward, and the pressure rod pushes the shaft sleeve two downward. Since the ball is in the groove of the shaft sleeve one at this time, the shaft sleeve two drives the shaft sleeve to move downward. During the downward movement, the ball enters the gap again. At this time, there is no blocking effect of the ball and the groove, and the operator does not press the shaft sleeve one. The shaft sleeve one rebounds automatically from the shaft sleeve two under the action of the spring two.

[0012] During installation, pressing sleeve 1 drives sleeve 2 to move toward the reel. After stopping pressing sleeve 1, spring 1 pushes sleeve 2 in the opposite direction toward the cover plate. During removal, the pressure rod drives sleeve 2 to move toward the reel. Sleeve 2 and sleeve 3 are connected, and the movement of sleeve 2 drives sleeve 3 to move in the same direction. The outer circumference of sleeve 3 contacts the inner cavity of the mounting seat, and the inner cavity of the mounting seat serves as a guide for the movement of sleeve 3, which is also a guide for the movement of sleeve 2.

[0013] Furthermore, the guide platform is T-shaped, and a boss 2 is opened on the inner wall of the center hole of the end of the sleeve three close to the guide platform. The boss 2 is located below the wider part of the T-shaped guide platform. The T-shaped guide platform limits the movement of the sleeve three, and the thinner part of the T-shaped guide platform and the inner wall of the inner cavity together serve as the movement guide of the sleeve three.

[0014] The inner cavity of the mounting seat and the guide platform together serve as the third guide of the shaft sleeve, wherein the guide platform also serves as a movement limit for the third shaft sleeve.

[0015] Furthermore, the center hole of the second sleeve is in a two-layer stepped shape, and the inner diameter of the center hole of the second sleeve is arranged from small to large in the direction from the cover plate to the reel; the variable diameter shaft is located at one end in the inner cavity, and a circle of limit platforms is fixed on its outer circumference, and the limit platforms are fixed to the guide platform; the smaller part of the center hole of the second sleeve is adapted to the variable diameter shaft, and the larger part of the center hole of the second sleeve is adapted to the limit platform; the limit platform limits the movement of the second sleeve; the spring is connected on the limit platform and is located between the guide platform and the second end of the sleeve.

During installation, the sleeve 1 is pressed to make the ball enter the groove, and the sleeve 1 and the cover plate are continued to be pressed, and the ball shrinks into the gap at the variable diameter shaft. At this time, there is no ball in the groove, and the sleeve 1 can be easily moved down until the cover plate contacts the tape reel. At this time, the hand is released, the sleeve 1 and the sleeve 2 rebound, the ball leaves the gap and re-enters the groove, the sleeve 1 cannot be pulled out from the sleeve 2, and the cover plate presses the tape reel to complete the installation of the tape reel. When disassembling, a pressure rod is needed. The pressure rod passes through the shaft sleeve 1 and can contact the shaft sleeve 2. Press the pressure rod, the pressure rod pushes the shaft sleeve 2 downward, and at the same time drives the shaft sleeve to move downward. As in the installation, when it continues to move downward, the ball will enter the gap of the reducer shaft. The difference from the installation is that the operator does not press the shaft sleeve 1 at this time. When the ball enters the gap, the shaft sleeve 1 rebounds automatically from the shaft sleeve 2 under the action of the spring 2, that is, the cover plate also detaches, remove the shaft sleeve 2, and then remove the reel to complete the disassembly.

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims. Example

[0032] A taping head with a simple installation structure comprises a base plate, a rotating assembly installed on the base plate, a cover plate 1 and an installation structure, such as Figure 1 and 2 As shown, the rotating assembly includes a rotating shaft 2, a bearing 3 and a mounting seat 4, the reel is mounted on the rotating shaft 2, and the mounting structure connects the cover plate 1 with the mounting seat 4; the mounting structure includes a movable part and a fixed part; the movable part is connected to the cover plate 1, and the fixed part is fixed to the mounting seat 4;

The sleeve 5 moves through the through hole in the center of the cover plate 1, and the pressure rod 6 moves into the center hole of the sleeve 5. The inner wall of the center hole of the sleeve 5 has a groove 14; the sleeve 5 is T-shaped, as shown in FIG. Figure 2 and 7 As shown, the spring 2 7 is sleeved on the thinner part of the T-shaped shaft sleeve 1 5, and the spring 2 7 is located between the shaft sleeve 1 5 and the inner wall of the central through hole of the cover plate 1. Figure 2 As shown, the inner diameter of the central through hole of the cover plate 1 is matched with the larger outer diameter of the T-shaped shaft sleeve 5.

[0034] like Figure 2 and Figure 3As shown, the fixed part includes a variable diameter shaft 10, a sleeve 29 and a spring 11. The variable diameter shaft 10 is fixed to the mounting seat 4. One end of the sleeve 29 is movably connected to the variable diameter shaft 10, and the other end is movably inserted into the center hole of the sleeve 15. From the cover plate to the reel direction, the pressure rod 6 and the sleeve 29 are sequentially arranged in the center hole of the sleeve 5; the spring 11 is installed at one end of the sleeve 29 close to the mounting seat 4; at least one through hole is opened on the outer diameter of the sleeve 29, and a through hole is arranged There is a ball 15 matched with the groove 14; the reducer shaft 10 has a reduced diameter portion 16, the diameter of the reduced diameter portion 16 is smaller than the diameter of other portions of the reducer shaft 10, so that there is a gap 13 between the reduced diameter portion 16 and the inner wall of the center hole of the sleeve 2 9; when the sleeve 2 9 is pushed to move toward the mounting seat 4, the spring 11 is compressed, and when the ball 15 reaches the reduced diameter portion 16, the ball 15 is squeezed, and the ball 15 shrinks into the through hole and enters the gap 13.

Figure 2 As shown, sleeve 15 is then put on sleeve 29, and sleeve 15 is pressed to move vertically downward, and ball 15 is stuck in the groove 14. Due to the cooperation of ball 15 and groove 14, and the close fit between sleeve 29 and reducer shaft 10, there is no space for ball 15 to extend, and sleeve 15 drives sleeve 29 to move downward. During the movement, reducer shaft 10 is always motionless. When sleeve 29 with ball 15 moves to the position where the diameter of reducer shaft 10 is smaller (gap 13), the downward force of sleeve 15 on ball 15 presses ball 15 into gap 13, and then sleeve 15 can be easily inserted until the cover plate contacts the reel and stops moving downward; after the hand is released, spring 27 rebounds to push sleeve 15 in the opposite direction, spring 11 rebounds to push sleeve 29 in the opposite direction, and ball 15 re-extends into groove 14, completing the installation of the cover plate. When spring 2 7 and spring 1 11 rebound, they push shaft sleeve 1 5 and shaft sleeve 2 9, and there is no structure to push the cover plate.

Since the ball 15 is located in the groove 14 of the sleeve 1 5 at this time, the sleeve 2 9 drives the sleeve 1 5 downward. During the downward movement, the ball 15 enters the gap 13 again. At this time, there is no cooperation and blocking effect between the ball 15 and the groove 14. The sleeve 1 5 automatically pops out of the sleeve 2 9 under the rebound of the spring 2 7. The sleeve 1 5 and the cover plate on it can be taken out, and then the reel is taken out to complete the disassembly. Different from the installation, the pressure rod 6 is used during disassembly.

[0040] During installation, pressing the sleeve 1 5 drives the sleeve 2 9 to move toward the reel. After stopping pressing the sleeve 1 5, the spring 1 11 pushes the sleeve 2 9 in the opposite direction to move toward the cover plate. During removal, the pressure rod 6 drives the sleeve 2 9 to move toward the reel. The sleeve 2 9 and the sleeve 3 8 are clamped together, and the movement of the sleeve 2 9 will drive the sleeve 3 8 to move in the same direction. The outer circumference of the sleeve 3 8 contacts the inner cavity of the mounting seat 4, and the inner cavity of the mounting seat 4 is the movement guide of the sleeve 3 8, that is, the movement guide of the sleeve 2 9.

[0041] like Figure 3 As shown, the guide platform 12 is T-shaped, and a boss 2 19 is opened on the inner wall of the center hole of the end of the sleeve 3 8 close to the guide platform 12, and the boss 2 19 is located below the wider part of the T-shaped guide platform 12.
