All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of description of the present application, and have no specific meaning by themselves. Thus, "module", "component" or "unit" may be used mixedly.

As shown in fig. 1 and 3, a part of the components of a printing base of a rotary press related to the present application is shown, including a front side plate 302, a rear side plate 301 opposite to and spaced from the front side plate 302, a printing plate roller (also referred to as a spindle) 200, and a spindle capping assembly 100.

As shown in fig. 1, in an operating state, the printing plate roller 200 is rotatably attached to the front side plate 302 and the rear side plate 301.

Specifically, in the illustrated embodiment, as shown in fig. 1 and 4 in conjunction, the front side of the printing plate roller 200 is disposed on the front side plate 302 by the spindle capping assembly 100. The rear side of the printing plate roller 200 is detachably disposed on the rear side plate 301 through a bearing assembly.

In the illustrated embodiment, as shown in fig. 4, the printing plate roll 200 includes a roll 202, a mandrel 204, a pusher 206, and a driver 208. Wherein, an independent driving motor is connected to the driving part 208, and the spindle 204 and the plate cylinder 202 are driven to rotate by the driving motor. The plate cylinder 202, the mandrel 204, and the driving portion 208 are well known in the art and will not be described in detail herein. The following focuses on the spindle gland assembly 100, an important component of the present application.

The pressing portion 206 is fixedly provided on the front side of the spindle 204. The pressing portion 206 is provided in a conical shape having a diameter gradually increasing from front to back. In this way, a technical effect that the urging portion is urged by the bearing member can be achieved.

In another modification, the pressing portion may alternatively be provided in a cylindrical shape as long as it is easily pressed by the bearing member.

As shown in fig. 5, the spindle capping assembly 100 includes a disk body detachably attached to a front side plate 302 of the printing bed, a bearing member 106 provided in the disk body so as to be movable forward and backward, a biasing member 110 for constantly pressing the bearing member 106 backward, and a stopper member 104 for stopping the bearing member 106.

Specifically, in the illustrated embodiment, the tray includes a containment body 108 and a cover 112. As shown in fig. 1, 5 and 6, the cover 112 is fixed to the front side of the accommodating body 108 by a plurality of circumferentially uniformly distributed screws.

As shown in fig. 3, 5 and 6, a handle 114 is secured to the cover 112 to facilitate access to the spindle gland assembly 100.

In one embodiment, the force applying member 110 comprises a plurality of compression springs arranged circumferentially uniformly. The front side of each compression spring abuts against the end surface of the cover 112, and the rear side of each compression spring abuts against the end surface of the bearing member 106.

As shown in fig. 6, a sleeve 102 matching the outer shape of the housing body 108 is provided on the front plate 302 of the printing block. Wherein the radius of the outer peripheral surface 1083 of the accommodating body 108 is gradually reduced from front to back (from top to bottom in fig. 6). In cooperation therewith, the radius of the inner circumferential surface of the sleeve 102 is gradually reduced from front to back (from top to bottom in fig. 6). In this manner, the technical effect of accurate positioning of the spindle gland assembly 100 can be achieved.

As shown in fig. 1, 3 and 6, the edge of the cover 112 is provided with a positioning protrusion 118, and correspondingly, the sleeve 102 is provided with a positioning recess 116.

Further, as shown in fig. 1, a locking assembly is provided on the front side plate 302. In one embodiment, the locking assembly includes a locking knob (not shown) and a locking aperture (not numbered) that is threadably coupled to the locking knob. Specifically, in the illustrated embodiment, 2 positioning protrusions 118 are provided on the edge of the cover 112, correspondingly, 2 positioning recesses 116 are provided on the sleeve 102, and 2 locking assemblies are provided on the front plate 302.

In addition, to prevent the bearing member 106 from coming out of the accommodating body 108, a stopper member 104 is provided. Specifically, the stop member 104 may be a snap spring, a retainer ring, a snap ring, or the like, among others. As shown in fig. 6, the rear side of the accommodating body 108 is provided with a stopper groove 1082 for placing the stopper member 104. The circlip is generally circular in shape and is notched at one end to easily fit into the stop groove 1082.

The accommodating body 108 has an accommodating space that accommodates the bearing member 106. The axial width of the accommodating space is larger than the axial width of the bearing member 106. Thereby, the bearing member 106 can move a predetermined distance in the axial direction in the housing body 108.

When the spindle gland assembly 100 is inserted into the sleeve 102 with the locating boss 118 aligned with the locating recess 116, the locking knob pushes the 2 locating bosses 118 rearward by rotating the locking knob until the locating bosses 118 fall into the locating recesses 116. At this time, the plurality of compression springs as the urging member 110 are compressed.

On the other hand, when the spindle gland assembly 100 is inserted into the sleeve 102, the tapered head of the pushing portion 206 drops into the bearing member 106. Further, the pressing portion 206 receives a pushing force in the pressing direction by the urging member 110, as shown in fig. 4. Therefore, the axial movement of the printing plate roller can be avoided, and the printing precision is improved.

Compared with the prior art, the utility model discloses following beneficial effect can be realized at least: the main shaft gland assembly comprises a disc body detachably connected to a front side plate of the printing seat, a bearing member arranged in the disc body in a manner of moving back and forth, a force application member for always pushing the bearing member backwards and a stopping member for stopping the bearing member.
