[0053] A locking rod 12 connected to a locking bearing 16 is rotatably mounted on the right side of the locking end plate 1 , and the rear side wall of the bearing 16 is limited by the locking rod 12 to lock the bearing 16 .

[0054] Specifically, the bottom of the locking rod 12 is rotatably connected to the locking end plate 1, and a through slot 11 (the through slot 11 is an open structure at the top and bottom) that cooperates with the locking rod 12 is opened on the rear side of the bottom of the locking end plate 1, and the bottom of the locking rod 12 is rotatably connected to the through slot 11 through a fixed pin shaft.

[0055] The locking rod 12 is rotated until the locking rod 12 is pressed against the side wall of the bearing 16 , and the locking rod 12 is in an inclined state.

[0056] In order to achieve the fastening of the lock rod 12, a locking component is provided at the top of the lock rod 12. After the locking component locks the top of the lock rod 12, the lock rod 12 is fastened and the bearing 16 is locked. Specifically, the locking component includes a U-shaped lock bar 13 provided on the locking end plate 1. The U-shaped lock bar 13 has a closed end 132 (the closed end 132 is bent) and an open end (the U-shape has an opening); the closed end 132 is located at the rear side of the open end (the rear end of the U-shaped lock bar 13 is the closed end 132). The closed end 132 is hooked on the top of the lock rod 12. In order to increase the stability of the lock, a protrusion 121 is provided backward on the top of the lock rod 12, and the closed end 132 is hooked below the protrusion 121.

[0057] The open end of the U-shaped locking bar 13 has two connecting ends 133 , ie, one connecting end 133 is located on the left side, and the other connecting end 133 is located on the right side.

[0058] A connector 14 that cooperates with the U-shaped locking strip 13 is provided on the top of the locking end plate 1. The U-shaped locking strip 13 is connected to the connector 14 as follows:

[0059] Connector 14:

[0060] The connecting member 14 includes a fastener (the longitudinal cross-sectional shape of the fastener is approximately L-shaped), an arc-shaped through slot 142 is opened on the rear end of the fastener (the arc-shaped through slot 142 is an open structure up and down), a pin shaft 1421 is fixedly connected to the arc-shaped through slot 142, a pin shaft sleeve 1422 is rotatably connected to the pin shaft 1421, a connecting column 1423 is welded to the bottom of the pin shaft sleeve 1422, and the connecting column 1423 is welded to the top position of the locking end plate 1. In the above manner, the connecting member 14 is connected to the top of the locking end plate 1.

[0061] At the same time, a handle 141 is connected to the front side wall of the fastener, and the handle 141 is used for easy operation.

[0062] The connection relationship between the U-shaped locking strip 13 and the connecting member 14 is as follows:

[0063] The two connection ends 133 are fixedly connected to the side walls of the fasteners through the connection end plates 131 , respectively. Meanwhile, the front end of the connection end 133 passes through the connection end plate 131 forward and is screwed with a first nut.

[0064] Specifically, the left connecting end 133 passes through the connecting end plate 131 forward and is then screwed with the first nut (i.e., the first nut is located at the front side of the connecting end plate 131). At the same time, the connecting end 133 on this side passes through the connecting end plate 131 to the right and is welded to the left side wall of the connecting member 14.

[0065] The connection end 133 on the right side passes through the connection end plate 131 forward and is screwed with the first nut. At the same time, the connection end 133 on this side passes through the connection end plate 131 to the left and is welded to the right side wall of the connecting member 14 .

[0066] After the U-shaped locking bar 13 is hooked on the locking rod 12 , the first nut is fastened to the connecting end 133 . Under the action of the first nut, the U-shaped locking bar 13 locks the locking rod 12 , thereby locking the bearing 16 .

[0067] In order to increase stability, second nuts are screwed on the two connection ends 133; the second nuts are located on the rear side of the connection end plate 131, so the connection end plate 131 is fastened using the first bolt and the second nut, and the second nut squeezes the connection end plate 131 during the process of screwing the second nut forward.

[0068] By adopting the above device, the first nut and the second nut are loosened, the U-shaped locking strip 13 is loosened, and the bearing 16 is unlocked.

[0069] The advantages of using the above device are:

[0070] The bearing 16 is locked and unlocked in a relatively simple manner.

[0071] Example 2 Packaging bag winding device

[0072] like Figure 1-7 As shown, this embodiment discloses a packaging bag rolling device based on the bearing locking device of embodiment 1.

[0073] The packaging bag winding device includes a winding roller 23, and the front and rear ends of the winding roller 23 are fixedly connected to a rotating shaft, and each rotating shaft is assembled on a bearing locking device. Specifically, the rotating shaft is rotatably connected to the bearing 16 on the bearing locking device, that is, the front and rear ends of the winding roller 23 each have a bearing locking device.

[0074] The packaging bag winding device also includes a bracket 22 , and the winding roller 23 is assembled at the end position of the right end of the bracket 22 after being assembled with a bearing locking device.

[0075] The bracket 22 includes a front end and a rear end (the front end and the rear end are the same, parallel to each other, and flush with each other). From left to right, the front end and the rear end are respectively divided into a first horizontal end 221, an inclined end 222 (with an inclined surface), a second horizontal end 223 (the second horizontal end 223 is lower than the first horizontal end 221), and an assembly portion 224 for assembling and locking the end plate 1.

[0076] The locking end plate 1 is fastened to the rear side wall of the front end portion and the front side wall of the rear end portion by a plurality of bolts.

[0077] At the same time, the assembly portion 224 has an opening 2241 that matches the assembly opening 15 (the opening 2241 is also semicircular and larger than the assembly opening 15 ). The opening 2241 is provided to facilitate the removal of the entire coiling roller 23 .

[0078] A plurality of limiting rods 21 are arranged between the front end and the rear end, and the limiting rods 21 are used to limit the roll material (film material or paper material) and increase the transmission length of the material. The front and rear ends of the limiting rods 21 are fixedly connected to the front end and the rear end respectively.

[0079] The upper and lower limit rods 21 are staggered and distributed at the first horizontal end 221, the inclined end 222, and the second horizontal end 223. Therefore, the coils pass through the limit rods 21 in an upper and lower staggered manner, thereby increasing the conveying length.

[0080] Working principle:

[0081] During the working process, if the coil (wound on the coil roller 23) needs to be replaced, first unlock the bearing 16 in the manner disclosed in the embodiment. After unlocking, the bearing 16 loses its lock and is in a free state. Lift the entire coil roller 23, first disengage the bearing 16 from the assembly opening 15, and then bypass the opening 2241 of the assembly opening 15 to remove the entire coil roller 23. Assemble the new pre-wound coil roller 23 to the assembly opening 15, lock the lock rod 12, and continue working.

[0082] The advantages of adopting the above device design are:

[0083] The bearing locking device is used to realize simple and fast replacement of the coiling roller 23. The pre-rolled coiling roller 23 is assembled to the assembly port 15 to realize fast replacement of the coiled material, which solves the problem that the coiling roller 23 cannot be removed and needs to be continuously re-rolled for production, resulting in a defect of a longer production cycle. At the same time, during the production process, if it is found that there is bad material on the coiled material, it is only necessary to remove the coiling roller 23 and replace it. When there is sufficient time later, the bad material part can be slowly removed. During the production process, there is no need to destroy the entire coiled material and re-produce in order to shorten the production cycle.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
