When the cotton cloth transfer device is used, firstly, the transfer device is placed on the side of the winding drum 5 wound with cotton cloth, then, the roll shafts on the two sides of the cotton cloth are correspondingly placed on the roll shaft supporting seats 6 on the two supporting blocks 2, on the transfer device, a worker pulls out the free end of the cotton cloth and winds the free end on the roll body of the cotton cloth to a certain extent, and simultaneously rotates the cotton cloth, so that the cotton cloth wrapping action is completed on the transfer device, the cotton cloth wrapping plate roller is completed, the cotton cloth plate roller is clamped and fixed together with the cotton cloth clamping device 3, so that the cotton cloth plate roller is stably limited on the transfer device, the cotton cloth is prevented from being damaged due to collision in the transfer process, and after clamping, the cotton cloth is cut off by the blade.

This kind of transfer device provides and is used for supporting the roller and can supply the roller to revolve around its central point in order to realize winding the roller supporting seat 6 on the version roller with the cotton cloth, realizes integrating transfer device with the function of package cotton cloth, only needs once transport action, reduces the transport link before transporting, reduces the impaired risk of colliding with to reduce the impaired risk before the shipment of version roller vanning, simultaneously, because utilize clamping device to press from both sides the cotton cloth of winding on the version roller when pressing from both sides tight version roller, need not to tie up the work, consequently can reduce material cost and cost of labor, thereby reduce the cost of whole product.

It will be appreciated that the smoother the support groove 61, the better the roller, so that the roller can reduce wear of the roller shaft or burrs during rotation, preventing problems of the roller during subsequent assembly to the machine in cooperation with bearings on the machine, for which reason the surface of the support groove 61 is provided with a smooth layer.

Example 2: referring to fig. 3-7, a sliding table 71 is disposed on the outer side of the supporting block 2, the sliding table 71 is slidably mounted on a seat plate 70 detachably connected with the bottom plate 1, the seat plate 70 and the bottom plate 1 can be detachably connected in an inserting manner, a first rotating shaft 72 and a second rotating shaft 73 are disposed on the sliding table 71 through a plurality of shaft mounting seats, a butt joint part 74 for butt joint with the shaft end of the driving shaft 41 and the shaft end of the roller shaft is respectively disposed at the shaft end of the first rotating shaft 72 and the shaft end of the second rotating shaft 73, and by moving the sliding table 71, the two butt joint parts 74 can be butt joint with the shaft end of the driving shaft 41 and the shaft end of the roller shaft simultaneously, so that the operation is simple; the first rotating shaft 72 and the second rotating shaft 73 are also connected through a gear transmission structure, the gear transmission structure at least comprises a first gear and a second gear, the first gear is fixedly arranged on the first rotating shaft 72, the second gear is fixedly arranged on the second rotating shaft 73, and in the scheme, the gear transmission structure also comprises a third gear which is arranged between the first rotating shaft and the second gear and is meshed with the first rotating shaft and the second gear.

When the roll shafts on both sides of the plate roll are placed on the two supporting seats 6, an external force is applied to the sliding table 71 to enable the sliding table 71 to approach the plate roll, the first abutting part 721 is abutted with the driving shaft 41, meanwhile, the second abutting part 731 is abutted with the roll shaft, cotton cloth is wound on the roll body of the plate roll to a certain extent, and the driving shaft 41 is rotated, on one hand, the driving shaft 41 enables the plate roll to rotate through structures such as the first rotating shaft 72, the gear transmission structure and the second rotating shaft 73, so that the plate roll fully completes the action of wrapping the cotton cloth, on the other hand, the driving shaft 41 enables the two-way screw rod 31 to rotate through transmission of the first bevel gear 43 and the second bevel gear 44, so that the two clamping blocks 32 of the clamping device 3 approach each other to clamp the plate roll, and after clamping, the cotton cloth is cut off by the blade.

By adopting the structure, the clamping and cotton wrapping work are performed simultaneously, the time consumption in a factory before transferring is reduced, the delivery and delivery efficiency of products is improved, trust of customers is gained, manual participation is reduced, if the cotton wrapping work is finished before the clamping, the manual participation is needed to maintain the state that the cotton wraps the plate roller, otherwise, the cotton is scattered, the subsequent plate roller transportation process is difficult to ensure that collision damage cannot occur, if the clamping is faster than the cotton wrapping work, the number of layers of the wrapped cotton is too small, and the anti-collision and anti-collision effects are affected. In addition, the seat board 70 is detachably connected with the bottom plate 1, the seat board 70 and all parts mounted on the seat board are separated from the bottom plate 1 after the plate roller is clamped and wrapped with cotton cloth, the seat board can be reused, and the seat board is not shipped simultaneously with the plate roller, so that the cost is reduced.

In this case, the two butting portions 74 have the same structure; the abutting portion 74 is provided with an axial abutting groove 741 and a radial through groove 742 communicated with the axial abutting groove 741, a transmission block 75 is slidably arranged in the radial through groove 742, a fixing plate 76 connected with the abutting portion 74 is arranged on the radial outer side of the radial through groove 742, a first spring 77 connected with the transmission block 75 is arranged on the fixing plate 76, the transmission block 75 is provided with two stress inclined planes 751 which are symmetrically arranged in the axial direction and a transmission surface 752 which is positioned on the radial outer side of the two stress inclined planes 751, the transmission surface 752 is used for acting on a key groove which is pre-opened on a roll shaft or a driving shaft 41, the transmission block 75 is further provided with a guide rod body portion 753 penetrating through the fixing plate 76, and the first spring 77 is sleeved on the guide rod body portion 753.

When the slide table 71 moves to cause the first and second shafts 72 and 73, the shaft ends of the driving shaft 41 and the shaft ends of the shaft shafts are inserted into the respective corresponding axial abutting grooves 741 and act on the relatively outer force inclined surfaces 751 in the axial abutting grooves 741 to cause the transmission block 75 to be lifted radially outwardly, and the slide table 71 is stopped until the shaft or the key groove on the driving shaft 41 moves to the axial position where the transmission block 75 is located, at which time, no matter whether the transmission block 75 is already caught in the corresponding key groove, the worker only needs to rotate the first shaft 72, the second shaft 73 rotates accordingly, the transmission blocks 75 on the first and second shafts 72 and 73 rotate circumferentially to be caught in the corresponding key grooves, and then, under the interaction of the transmission surfaces 752 and the key grooves, power is transmitted to the driving shaft 41 and the shaft to cause the rotation of the driving shaft 41 and the shaft. By the structure, the two actions of moving the sliding table 71 and rotating the rotating shaft 72 by one move one rotation are realized, so that the butt joint is convenient and quick, the time consumption in a factory before transferring is reduced, and the delivery and delivery efficiency of products is improved. When the seat plate 70 and the bottom plate 1 need to be separated for repeated use, the sliding table 71 is given a reverse force to move reversely, wherein the seat plate 70 is directly pulled out in the simplest way.

The support block 2 is provided with a screw rod mechanism for providing power for the sliding table 71, and the screw rod mechanism can realize self-locking after the sliding table 71 slides, so that the sliding table 71 is limited.
