Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, an inflatable feeding device disclosed in the embodiment of the present application mainly includes a support 11, a sleeve 12, a first driving device 13, a first positioning ring 14, a pull rod 15, a second positioning ring 16, a second driving device 17, a fixing sleeve 18, and the like, and specifically, the support 11 is placed on the floor or a workbench of a workshop and mainly plays a role of supporting.

The sleeve 12 is mounted on the bracket 11 and is rotatably connected to the bracket 11, i.e. the sleeve 12 can rotate under external force. The power for rotating the sleeve 12 is provided by a first driving device 13, and the first driving device 13 can be placed on the ground or a workbench, or can be fixedly arranged on the bracket 11.

In some possible implementations, the first driving device 13 uses a motor and a speed reducer, an output end of the motor is connected to an input end of the speed reducer, an output shaft of the speed reducer is connected to the sleeve 12 through a transmission device, and the transmission device may use a gear set, a sprocket set, or a synchronous belt.

It will be appreciated that one end of the sleeve 12 is suspended so that the roll can be placed directly on the sleeve 12 without the need to remove or otherwise move the accessory.

A first retaining ring 14 is also fixed to the sleeve 12, the first retaining ring 14 being adapted to engage a second retaining ring 16 to clamp a retaining sleeve 18 that is fitted to the sleeve 12, such that the retaining sleeve 18 is able to rotate with the rotation of the sleeve 12.

The second positioning ring 16 is arranged on the pull rod 15 and is rotatably connected with the pull rod 15, one end of the pull rod 15 penetrates through the sleeve 12 and then is connected with the second driving device 17, the second driving device 17 is used for pulling the pull rod 15 to slide along the axial direction of the pull rod, and when the pull rod 15 slides, the second positioning ring 16 moves towards the direction close to or away from the first positioning ring 14.

The power for sliding the pull rod 15 is provided by the second driving device 17, and the second driving device 17 may be fixed on the ground or the workbench, or may be fixedly installed on the bracket 11.

In some possible implementations, the second driving means 17 uses a pneumatic cylinder.

The second retaining ring 16 contacts the sleeve 18 and applies pressure to the sleeve 18 as it approaches the first retaining ring 14, and the first retaining ring 14, the second retaining ring 16, and the sleeve 18 rotate with it if the sleeve 12 rotates.

At the same time, when the pressure applied by the first positioning ring 14 and the second positioning ring 16 to the fixing sleeve 18 is larger, the surface of the fixing sleeve 18 is slightly deformed, and the connection with the material roll is more stable.

Of course, in order to prevent the fixing sleeve 18 from sliding during the process of driving the material roll, the sectional area of the first positioning ring 14 is reduced in the direction away from the bracket 11, so that the pressure of the contact surface of the first positioning ring 14 and the fixing sleeve 18 can be increased.

Similarly, the cross-sectional area of the second positioning ring 16 tends to decrease in the direction toward the bracket 11, also in order to increase the pressure at the contact surface of the second positioning ring 16 with the retaining sleeve 18.

In a specific use scenario, when the material roll on the fixing sleeve 18 is consumed, the first driving device 13 stops rotating, and the second driving device 17 pushes the pull rod 15 to drive the second positioning ring 16 to move away from the first positioning ring 14.

At this point, the worker removes the inner tube (remaining after the roll is consumed) from the pouch 18 and then applies a new roll to the pouch 18.

In the whole process, the staff only need take off the inner tube and install new material and roll up to the fixed of material book also is automatic going on, and the degree of automation of whole process is higher, the effectual change time of rolling up the material that has shortened has improved production efficiency.

On the whole, the inflatable feeding device provided by the embodiment of the application realizes automatic assembly and disassembly of the material roll to a certain extent, and shortens the replacement time of the material roll. If the manipulator is matched for operation, the automatic replacement of the material roll can be realized. The manipulator is responsible for lifting the material roll and then moving the material roll to the fixing sleeve 18 and then sleeving the material roll on the fixing sleeve 18, and then the material roll can be automatically clamped by the inflatable feeding device in the embodiment of the application, so that the production is continued.

Referring to fig. 2, as an embodiment of the inflatable feeding device, a first chamfer 181 is provided at an end of the fixing sleeve 18 close to the first positioning ring 14, and the first chamfer 181 is used to increase a contact area between the fixing sleeve 18 and the first positioning ring 14.

It will be appreciated that the area of the contact surface of the sleeve 18 with the first retaining ring 14 increases as the first chamfer 181 appears, and the contact surface is also an inclined surface, which provides greater friction and avoids relative sliding between the sleeve 18 and the first retaining ring 14.

Referring to fig. 2, as an embodiment of the inflatable feeding device, a second chamfer 182 is provided at an end of the fixing sleeve 18 close to the second positioning ring 16, and the second chamfer 182 is used to increase the contact area between the fixing sleeve 18 and the second positioning ring 16.

It will be appreciated that the second chamfer 182 increases the area of the contact surface of the fastener sleeve 18 with the second retaining ring 16, and the contact surface is also a sloped surface, which provides greater friction to prevent relative sliding between the fastener sleeve 18 and the second retaining ring 16.

Referring to fig. 3, as an embodiment of the inflatable feeding device provided by the present application, a protrusion 183 is added on the outer wall of the cover 18, and the protrusion 183 is used to increase the friction between the cover 18 and the material roll.

It will be appreciated that the outer surface of the pouch 18 is relatively smooth and may slip during continued rotation, and that with the addition of the projections 183, when the pouch 18 is slightly deformed, the pressure of the contact portions of the projections 183 with the roll increases and, correspondingly, the tendency of the roll to slip decreases.

In some possible implementations, the projections 183 are in the form of bars, the axis of which is parallel to the axis of the pouch 18.

It should be understood that one end of the sleeve 12 is suspended, and will inevitably bend during long-term use, which will cause the material roll to shake during rotation, and therefore, as a specific embodiment of the inflatable feeding device provided by the application, please refer to fig. 4, a moving module 21, a base 22, an elevating platform 23 and a third driving device 25 are further added, specifically, the moving module 21 is installed on the support 11, and a base 22 is installed thereon, the base 22 can reciprocate under the driving of the moving module 21, and the elevating platform 23 is fixedly installed on the base 22, can move along with the movement of the base 22, and can move in a direction close to or far from the base 22.

The dotted line part in the figure is another position of the moving module 21, the base 22, the elevating table 23 and the third driving means 25, and the height of the elevating table 23 at the dotted line position is lowered.

The power of the elevating platform 23 during movement is provided by the third driving device 25, both ends of the third driving device 25 are respectively fixedly connected to the base 22 and the elevating platform 23, when the elevating platform 23 is extended, the elevating platform 23 moves in the direction away from the base 22, and when the elevating platform 23 is shortened, the elevating platform 23 moves in the direction close to the base 22.

The lifting platform 23 is further provided with a groove 24 matched with the pull rod 15, and when the lifting platform 23 moves to a position right below the pull rod 15, the third driving device 25 can drive the lifting platform 23 to move towards a direction close to the pull rod 15 until the pull rod 15 is contacted with the inner wall of the groove 24.

At this time, the lifter 23 can hold the end of the rod 15 in contact with the rod, thereby preventing the sleeve 12 from bending.

Referring to fig. 4, further, a friction plate 26 is added on the inner wall of the groove 24, and the friction plate 26 is used to reduce the wear of the pull rod 15 and the lifting platform 23, it should be understood that, in the long-term use process, the pull rod 15 and the lifting platform 23 are inevitably worn, and after the friction plate 26 is added, the problem of wear of the lifting platform 23 can be solved, and if the hardness of the material of the friction plate 26 is adjusted to be lower than that of the material of the pull rod 15, the wear of the pull rod 15 can be avoided by sacrificing the friction plate 26.

In some possible implementations, the friction plate 26 is made of copper or teflon.
