Abstract

The present invention provides a backing paper winding device applied to a filament winding machine, comprising: a driving assembly, a guiding assembly, a bearing assembly and a locking assembly. The driving assembly includes a driving member and a rotating shaft. One end of the backing paper is attached to the surface of the backing paper reel. The locking assembly is installed at the end of the rotating shaft to clamp the backing paper reel. Subsequently, the driving member is controlled to drive the backing paper reel to rotate to wind the backing paper. After winding, the locking assembly is detached from the rotating shaft, and the backing paper reel is withdrawn from the rotating shaft. Since the surface of the backing paper reel is provided with an axially extending empty groove, the backing paper reel can be compressed by squeezing the backing paper wound outside the backing paper reel, so that the outer wall of the backing paper reel squeezes the empty groove, and the outer diameter of the backing paper reel becomes smaller under extrusion, so as to take out the backing paper reel from the wound backing paper tube.

[0035] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0036] The backing paper winding device provided in this embodiment is applied to a fiber placement machine.

[0037] Referring to Figures 1 to 6 , the backing paper winding device includes: a driving assembly 100, a guiding assembly 200, a bearing assembly 300, and a locking assembly 400.

[0038] Among them, the driving component 100 includes a driving member 110 and a rotating shaft 120. One end of the driving member 110 is connected to the automatic fiber placement machine, and the rotating shaft 120 is in transmission connection with the driving shaft of the driving member 110. The guiding component 200 includes a connecting member 210 and a rotating member 220. The connecting member 210 is connected to the driving member 110. The rotating member 220 is disposed around the rotating shaft 120 and rotates following the rotating shaft 120. The rotating member 220 is rotatably connected to the connecting member 210, and a limiting portion 221 is provided on the rotating member 220. The bearing component 300 includes a backing paper reel for winding the backing paper 500. An axially extending empty groove 310 is formed on the surface of the backing paper reel. The backing paper reel is sleeved outside the rotating shaft 120. A positioning portion is provided at one end of the backing paper reel and is in mating connection with the limiting portion 221 so that the backing paper reel rotates following the rotating shaft 120. The locking component 400 is detachably disposed at one end of the rotating shaft 120 away from the guiding component 200 and is in clamping cooperation with the connection end to clamp the bearing component 300.

[0039] Specifically, in this embodiment, the driving member 110 is disposed on the automatic fiber placement machine. The rotating shaft 120 is in transmission connection with the driving member 110. The rotating member 220 is connected to the driving member 110 through the connecting member 210, so that the relative positions of the connecting member 210 and the driving member 110 are kept fixed. The backing paper reel is sleeved on the rotating shaft and is in transmission connection with the rotating member 220.

[0040] Under this structure, the backing paper reel rotates following the driving member 110, and the cooperation between the positioning portion and the limiting portion 221 can ensure the connection structure between the backing paper reel and the rotating member 220, avoiding the backing paper reel from moving or the rotating shaft 120 being unable to drive due to excessive weight.

[0041] When using the backing paper winding device, first attach one end of the backing paper 500 to the surface of the backing paper reel, and install the locking component 400 to the end of the rotating shaft 120 to clamp the backing paper reel. Subsequently, control the driving member 110 to drive the backing paper reel to rotate to wind the backing paper 500.

[0042] After winding, detach the locking component 400 from the rotating shaft 120, and pull out the backing paper reel from the rotating shaft 120. Since the axially extending empty groove 310 is provided on the surface of the backing paper reel, the backing paper reel can be compressed by squeezing the backing paper 500 wound outside the backing paper reel, so that the outer wall of the backing paper reel squeezes the empty groove 310. The outer diameter of the backing paper reel becomes smaller under extrusion, so as to take out the backing paper reel from the wound backing paper 500 in a roll. The disassembly is very simple and labor-saving, thereby improving the recycling efficiency of the backing paper 500 and avoiding damage to the backing paper 500.

[0043] In this embodiment, the rotating member 220 is an annular rotating sleeve. A slot for insertion is formed by spacing the outer wall of the rotating sleeve from the rotating shaft 120, and the limiting portion 221 is located within the slot for insertion. The backing paper reel is sleeved on the rotating shaft 120 and inserted into the slot for insertion, and the positioning portion is snap-fitted with the limiting portion 221.

[0044] The annular rotating sleeve surrounds the rotating shaft 120 and is spaced from the rotating shaft 120, so that a slot for insertion is formed between the inner wall of the annular rotating sleeve and the outer wall of the rotating shaft 120. When installing the backing paper reel, it can be directly inserted into the slot for insertion, which plays a guiding role when installing the backing paper reel. After the backing paper 500 installation cylinder is installed into the slot for insertion, the positioning portion and the limiting portion 221 are snap-fitted, enabling the backing paper reel to rotate together with the annular rotating sleeve, ensuring the transmission between the backing paper reel and the driving member 110.

[0045] Among them, in this embodiment, the limiting portion 221 is a limiting pin, and the positioning portion is a positioning groove adapted to the limiting pin. An installation hole is provided on the inner wall of the annular rotating sleeve, and the limiting pin is connected to the installation hole by screw thread fit. The positioning groove is disposed opposite to the installation hole so that the limiting pin is inserted into the positioning groove.

[0046] Specifically, in this embodiment, the limiting pin is screwed tightly into the installation hole by means of screw thread fit. The installation hole provided at the end of the backing paper 500 installation cylinder is adapted to the limiting pin. When the backing paper reel is inserted into the slot for insertion, the limiting pin can be inserted into the installation hole. In this structure, the backing paper reel and the annular rotating sleeve are snap-connected through the limiting pin and the installation hole. The backing paper reel can move axially. When the limiting pin rotates with the annular rotating sleeve, it can drive the backing paper reel to rotate together, realizing the transmission connection between the driving member 110 and the backing paper reel.

[0047] In this embodiment, the driving assembly 100 further includes: a bearing 130. One end of the bearing 130 is connected to the driving shaft of the driving member 110, and the other end of the bearing 130 is connected to the rotating shaft 120.

[0048] Among them, in this embodiment, the bearing 130 can support the driving shaft, ensure its stable rotation, and efficiently transmit the power of the driving member 110 to the rotating shaft 120. At the same time, it reduces friction and improves the system efficiency. And it can ensure the centering and bear various loads, thus ensuring the stability of the system under complex working conditions.

[0049] In this embodiment, the backing paper winding device further includes a mounting bracket 140. The mounting bracket 140 is provided with a shaft hole and a connection hole for connecting an automatic fiber placement machine. The driving member 110 is disposed on one side of the mounting bracket 140 and connected to the mounting bracket 140, and the bearing 130 is disposed within the mounting bracket 140. The driving shaft of the driving member 110 passes through the shaft hole and is in transmission connection with the bearing 130.

[0050] Specifically, the driving member 110 in this embodiment is a driving motor. The driving motor is inserted and locked to the mounting frame 140 by screws. The rotating shaft of the driving motor is connected to the bearing 130 after passing through the shaft hole. There is an installation space inside the mounting frame 140 in this embodiment, and the bearing 130 is arranged in the installation space, so that the mounting frame 140 can cover the outside of the bearing 130 and protect the bearing 130, preventing sundries from entering the bearing 130 and affecting the service life of the bearing 130.

[0051] In this embodiment, the driving assembly 100 further includes an adapter seat 150, an output disc 160 and a coupling 170. The adapter seat 150 is sleeved outside the driving shaft of the driving member 110 and is located inside the bearing 130. The driving member 110 is in transmission connection with the bearing 130 through the adapter seat 150. One end of the output disc 160 is in transmission connection with the bearing 130, and the other end is in transmission connection with the rotating shaft 120. The coupling 170 is respectively connected to the output disc 160 and the rotating shaft 120. The adapter seat 150, the output disc 160 and the coupling 170 are all located inside the mounting frame 140.

[0052] The adapter seat 150 in this embodiment is sleeved outside the driving shaft of the driving member 110 and is located inside the bearing 130, thereby connecting the driving shaft and the bearing 130 to form a transmission connection. Through the adapter seat 150, the rotational motion of the driving motor can be smoothly transmitted to the bearing 130. The adapter seat 150 provides a transition structure for the driving shaft and the bearing 130, thus ensuring a tighter and more stable fit between the driving shaft and the bearing 130.

[0053] Moreover, one end of the output disc 160 in this embodiment is in transmission connection with the bearing 130, and the other end is in transmission connection with the rotating shaft 120. Thus, the rotational motion from the bearing 130 is transmitted to the rotating shaft 120. The output disc 160 serves as an intermediate link to ensure the continuity and stability of power transmission, can reduce the stress concentration caused by direct connection, and protect the rotating shaft 120 and the bearing 130 from excessive impact force.

[0054] The coupling 170 is respectively connected to the output disc 160 and the rotating shaft 120 to connect the output disc 160 and the rotating shaft 120 to form a complete transmission chain. The coupling 170 can compensate for the small deviation between the two shafts within a certain range, ensure the reliability and flexibility of the transmission, and can also transmit torque, smoothly transmitting the rotational motion from the output disc 160 to the rotating shaft 120.

[0055] Among them, similarly, the adapter seat 150, the output disc 160 and the coupling 170 in this embodiment are all arranged in the installation space, so that the mounting frame 140 can provide an installation space for the above structures and protect the above structures. At the same time, it can also ensure the stability and alignment of the above structures.

[0056] In this embodiment, the driving assembly 100 further includes an inner ring spacer 180 and an outer ring spacer 190. The inner ring spacer 180 is disposed between the inner wall of the bearing 130 and the output disk 160. The outer ring spacer 190 is disposed on the outer wall of the bearing 130. Both the inner ring spacer 180 and the outer ring spacer 190 are located within the mounting bracket 140.

[0057] Specifically, in this embodiment, the inner ring spacer 180 is disposed between the inner wall of the bearing 130 and the output disk 160, which can prevent the inner wall of the bearing 130 from directly contacting the output disk 160, thereby reducing friction and wear. And it can ensure an appropriate spacing between the inner wall of the bearing 130 and the output disk 160, avoiding interference caused by thermal expansion or other factors. At the same time, it can also ensure that the output disk 160 maintains precise centering during rotation, thereby improving the operating precision of the system.

[0058] Similarly, the outer ring spacer 190 is disposed on the outer wall of the bearing 130, so as to prevent the outer wall of the bearing 130 from directly contacting the mounting bracket 140 or other components, reducing friction and wear, and ensuring an appropriate spacing between the outer wall of the bearing 130 and the surrounding structure, avoiding interference caused by thermal expansion or other factors. In addition, the outer ring spacer 190 can also enhance the supporting effect of the outer wall of the bearing 130, ensuring the stability of the entire driving assembly 100.

[0059] In this embodiment, the locking assembly 400 includes a baffle 410 and a locking member 420. The baffle 410 is provided with a first screw hole and a jack 411. One end of the rotating shaft 120 far from the driving member 110 is provided with a second screw hole and a locking portion 121. The locking member 420 passes through the jack 411 and is in threaded engagement with the locking portion 121, and the positions of the first screw hole and the second screw hole are opposite.

[0060] The baffle 410 is mounted on the end of the rotating shaft 120 through the locking member 420. Specifically, after the liner paper roll is installed on the rotating shaft 120, the baffle 410 is buckled on the end of the rotating shaft 120 far from the driving member 110, and the first screw hole and the second screw hole are aligned. The locking member 420 is inserted into the first screw hole and screwed into the second screw hole to lock and position the baffle 410. Subsequently, a screw is inserted into the jack 411 and screwed into the locking portion 121 to further lock the baffle 410, so that the baffle 410 is firmly disposed at the end of the rotating shaft 120, realizing the clamping of the liner paper roll.

[0061] When disassembling the liner paper roll, first disassemble the screw in the jack 411 and the locking portion 121. Subsequently, the locking member 420 is unscrewed from the second screw hole and withdrawn from the first screw hole and the second screw hole, and then the baffle 410 can be disassembled. At this time, the liner paper roll can be removed along the rotating shaft, and the disassembly is very convenient.

[0062] In this embodiment, the locking member 420 is a ball head locking pin, and the locking portion 121 is a latch sleeve adapted to the ball head locking pin.

[0063] The threaded fit between the ball locking pin and the latch sleeve provides a reliable mechanical connection, ensuring the firmness of the baffle 410 on the rotating shaft 120 .

[0064] Among them, the ball head locking pin has high installation accuracy, excellent locking performance, and is very easy to install and disassemble. It can withstand long-term cyclic loads, has a long service life, and has a low frequency of maintenance and replacement.

[0065] In this embodiment, the outer wall of the rotating shaft 120 and the inner wall of the liner paper roll are clearance-matched. There are a plurality of empty slots 310, and the plurality of empty slots 310 are arranged at intervals along the circumference of the liner paper roll.

[0066] There is a certain gap between the outer wall of the rotating shaft 120 and the inner wall of the liner paper roll, which can facilitate the loading of the liner paper roll.

[0067] The plurality of empty grooves 310 can provide a larger shrinking range. When removing the rolled liner 500, the staff can manually pinch the surface of the liner 500 to easily compress the empty grooves 310 on the surface of the liner roll, thereby shrinking the liner roll and facilitating the removal of the liner 500.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
