Description

Technical Field

[0001] The utility model belongs to the technical field of winding material feeding, and particularly relates to a rotary feeding device. Background Art

[0002] At present, there are many winding rotary feeding devices for materials such as non-woven fabrics. Generally, the drum and the rotating shaft on the winding rotary feeding device are integrated. When winding, only one end of the material needs to be directly fixed on the drum, and then the power equipment on the drum is started. As the drum rotates, the material winds or unwinds on the drum.

[0003] In addition, there are also some winding rotary feeding devices where the drum and the rotating shaft are separated. That is, the rotating shaft is removed from the bracket, and then the drum sleeve is sleeved on the rotating shaft, and then the rotating shaft with the drum is installed on the bracket. For example, a film traction rotary feeding device disclosed in the publication number CN221396466U specifically discloses that when the winding shaft is separated from the clamping block, the motor is started, so that the assisting block at the front end of the motor rotates. The assisting block drives the mounting column to link the connecting block and the mounting block to rotate. At the same time, the mounting block slides up and down inside the lower end of the limiting column, and at the same time, the limiting column slides back and forth at the lower end of the positioning rod. Finally, the mounting block drives the bearing plate to rotate counterclockwise from bottom to top, and the movement track is to draw a rectangle, lifting and moving the winding shaft backward, removing the wound film, and making the motor rotate in the reverse direction, moving the new winding shaft to the interface of the clamping block, and after clamping, it can be rewound. It can be seen that the process of the winding shaft detaching from the device is extremely cumbersome and the operation is extremely troublesome, seriously affecting the production operation efficiency and thus increasing the production cost.

Detailed Embodiment

[0036] In order to understand the technical means, creative features, achieved purposes and effects of the present utility model easily, the present utility model will be further described below with reference to specific drawings.

[0037] As shown Figures 1-9 in the figure, a rotary feeding device includes a bracket 1 and also includes a torque relay entity which is composed of an air shaft 2, a connecting shaft 5 and a special-shaped pin shaft 13. The special-shaped pin shaft 13 is detachably connected to the connecting shaft 5, and the connecting shaft 5 is detachably connected to the air shaft 2. Moreover, the air shaft 2, the connecting shaft 5 and the special-shaped pin shaft 13 are sequentially rotationally coupled and installed on the bracket 1. The torque coupling ring position is continuously closed along the axial direction of the connecting shaft 5. A roller 10 is arranged below the connecting shaft 5, and the edge of the torque coupling ring position is in rolling contact with the roller 10. The axis where the roller 10 is located is parallel to the connecting shaft 5, that is, the torque coupling ring position is a concave portion formed on the circumferential surface of the connecting shaft 5 by two parallel flange rings. A roller 10 is also rotatably arranged on the bracket 1, and the roller 10 is in rolling contact with the concave portion formed by the torque coupling ring position; (in this solution, preferably, the torque coupling ring position includes two roller flanges 11 arranged on the connecting shaft 5. The two roller rings form a torque coupling ring position 12 on the connecting shaft 5, and the two rollers 10 are symmetrically arranged on the two outer sides of the circumferential surface of the rotating shaft 5 on the bracket 1 and are both installed obliquely below the connecting shaft 5. The roller 10 is in rolling contact with the torque coupling ring position 12, and the rotating shaft where the roller 10 is located is parallel to the connecting shaft 5).

[0038] A driving component is arranged on the bracket 1. The driving component includes a motor 3 and a speed reducer 4. The motor 3 is fixed on the bracket 1 through a mounting seat. The speed reducer 4 is installed on the motor 3. The output end of the speed reducer 4 is key-connected to the special-shaped pin shaft 13, and the output end of the motor 3, the input end of the speed reducer 4, the output end of the speed reducer 4 and the special-shaped pin shaft 14 are sequentially output-coupled. Specifically: the output end of the motor 3 is connected to the input end of the speed reducer 4. When the motor 3 is driving, the rotation speed is attenuated through the output end of the speed reducer 4 and the torque relay entity, so that the speed of the reel 15 on the air shaft 2 during feeding is much smaller than the rotation speed of the motor 4, thereby realizing slow feeding;

[0039] The special-shaped pin shaft 13 has a flange portion and a pin connecting rod portion 131 formed on the flange portion. A flange surface 134 is arranged on the flange portion. A stop step 133 and a keyway 132 are formed on the pin connecting rod portion 131. The keyway 132 is located between the flange surface 134 and the stop step 133. With the above solution, the purpose is to use the flange surface 134 to be bolt-connected to the connecting shaft 5, the stop step 133 is installed on the mounting seat, and the keyway 132 on the special-shaped pin shaft 13 is installed on the output shaft of the speed reducer 4 through a key.

[0040] The connecting shaft 5 is fixed on the special-shaped pin shaft 13 through bolts, and the air shaft 2 is fixed on the connecting shaft 5 through bolts.

[0041] One end of the connecting shaft 5 is provided with a connecting hole 16. The connecting hole 16 and the flange surface 134 on the special-shaped pin shaft 13 are bolted together. The connecting shaft 5 is also provided with mounting holes 17, and the mounting holes 17 and the air shaft 2 are bolted together.

[0042] The connecting hole 16 and the mounting holes 17 are both located at one end of the connecting shaft 5. The mounting holes 17 are located on one side of the connecting hole 16. The interior of the connecting shaft 5 is provided with a hollow chamber. One end of the air shaft 2 extends into the hollow chamber and is fixed to the mounting holes 17 by bolts.

[0043] The number of the connecting holes 16 is several and they are arranged in a ring on the connecting shaft 5. The number of the mounting holes 17 is four. The four mounting holes 17 are arranged in a rectangle on the connecting shaft 5 and are located inside the connecting holes 16 arranged in a ring on the connecting shaft 5.

[0044] The air shaft 2 is provided with two roller flanges 11. The two roller flanges 11 on the air shaft 2 also form a torque coupling ring position 12 on the air shaft 2. The bracket 1 is also rotatably mounted with rollers 10. The rollers 10 are in rolling contact with the concave portions on the torque coupling ring position 12 on the air shaft 2.

[0045] The bracket 1 is mounted with a roller seat 9. The roller seat 9 is rotatably sleeved with a roller 10 through a rotating shaft. The roller 10 is in rolling contact with the concave portions on the torque coupling ring position 12.

[0046] The roller seat 9 is provided with a blocking portion for preventing the air shaft 2 from falling off the bracket 1 during rotation.

[0047] The mounting seat includes a base 7 and a mounting plate 6. The base 7 is mounted on the bracket 1. The mounting plate 6 is slidably mounted on the base 7. The motor 3, the reducer 4, the connecting shaft 5, the special-shaped pin shaft 13 and the air shaft 2 are all mounted on the mounting plate 6.

[0048] The base 7 is provided with linear guide rails 18. The guide shoes 19 are slidably arranged on the linear guide rails 18. The mounting plate 6 is fixedly mounted on the guide shoes 19.

[0049] The mounting plate 6 and the base 7 are respectively provided with positioning holes for inserting a plug pin into the positioning holes on the mounting plate and the positioning holes on the base 7 respectively to position the mounting plate 6 after it slides on the base 7.

[0050] The bracket is also respectively provided with a sensor 8 and a control panel 14. The sensor 8 is used to measure the thickness of the material wound on the reel 15 and the thickness after the reel 15 unwinds the material. The sensor 8 is electrically connected to the control panel 14. The control panel 14 is electrically connected to the motor 3 and the reducer 4 respectively.

[0051] The sensors 8 provided on the support 1 are respectively provided in two on each leg of the support 1, and there is a certain height difference between the two sensors 8 on one leg. This height difference is set according to the actual use situation. The purpose is that the thickness of the raw material wound by the reel 15 is within this height difference. If it exceeds this height difference, the sensor 8 will transmit a signal to the control panel 14, and the control panel 14 will adjust the rotation speed of the motor 3 to ensure the stability of the feeding. Among them, the feeding stability means that as the output end of the motor 3 rotates, the output end of the speed reducer 4 rotates, so that the overall formed by the special-shaped pin shaft 13, the connecting shaft 5 and the air shaft 2 rotates on the support 1, thereby causing the reel 15 to rotate, so as to realize feeding when the reel 15 rotates (it should be noted that an external traction device is provided at the other end of the material to traction the material to perform the feeding operation under the operation of this device); as the rotary feeding device operates, the raw material on the reel 15 will become less and less, that is, the thickness formed by the reel plus the raw material will also become thinner and thinner. However, the motor 3 controls the rotation speed, that is, the circumferential speed, and the stability of the feeding length is considered by the linear speed. Therefore, the above control is required to ensure the stability of the feeding.

[0052] The working principle of the present utility model during winding is as follows: First, start the motor 3 through the control panel 14. The output end of the motor 3 starts to rotate, thereby driving the rotation of the shaft on the speed reducer 4, and then the special-shaped pin shaft 13, the connecting shaft 5 and the air shaft 2 rotate under the rolling of the rollers 10 and the concave parts on the torque coupling ring position 12. Through the traction of external equipment, the reel 15 located on the air shaft 2 winds or releases materials (such as non-woven fabrics, non-metallic composite materials, leather, polyester, PE, etc.).

[0053] The working principle of the present utility model for installing the reel is as follows:

[0054] First, disassemble the bolts connecting the connecting shaft 5 and the air shaft 2, then pull out the air shaft 2 from the connecting shaft 5, so that the torque coupling ring position 12 on the air shaft 2 leaves the roller 10, thereby making one end of the air shaft 2 tilt relative to the support 1. Then, put the reel 15 on the air shaft 2, and then insert the end of the air shaft 2 into the hollow inner cavity in the connecting shaft 5, and then tighten the bolts.

[0055] Move the mounting plate 6 on the linear guide rail 18 of the base 7 through the guide shoe 19, so that the positions of the motor 3, the speed reducer 4, the special-shaped pin shaft 13 and the connecting shaft 5 on the support 1 are changed, so that air shafts 2 of different lengths can be selected according to actual practical needs, and with the cooperation of the key grooves on the special-shaped pin shaft 13, to meet the winding operations of materials of different lengths. Specifically, a key matching the key groove 132 is provided on the speed reducer 4. When the motor 3 and the speed reducer 4 slide on the base 7 along with the mounting plate 6, the key also slides in the key groove 132, and after the sliding is completed, the key is positioned in the key groove 132.

[0056] It should be noted that an air nozzle and a key bar (not shown in the figure) are also provided on the air shaft 2 for connecting an air pipe. Under the action of an external power source (such as an air pump), gas reaches the air shaft 2 through the air pump, the air pipe and the air nozzle, so that the key bar on the outer surface of the air shaft 2 bulges through high-pressure inflation, thereby fixing the reel 15 (the reel 15 is sleeved on the air shaft 2) on the air shaft 2. After deflation, the key bar quickly retracts, facilitating the unloading of the reel 15.

[0057] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and various changes and improvements may occur without departing from the spirit and scope of the present invention, and all such changes and improvements fall within the scope of the present invention as claimed.
