Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines, and in particular relates to a fixed shaft sleeve for a water roller of a printing machine. Background Art

[0002] The function of the printing press water roller fixed sleeve (hereinafter referred to as "sleeve") is to fix the water roller shaft and the adjusting gear and protect the inner hole of the adjusting gear from wear. In daily use, there is a bearing connection between the water roller shaft and the water roller, and the shaft is fixed. However, when the bearing is rusted and stuck, it may drive the shaft to rotate. After the sleeve is worn, it can be replaced separately. However, in actual operation, the inner hole of the sleeve is smooth and embedded in the adjusting gear. It cannot be removed from the outside. It can only be removed by disassembling the transmission side housing and connecting parts (such as Figure 2 As shown in the figure, using a copper rod to knock it inwards from the outside will restore the original position and all connecting parts after installation. It takes 8 hours to disassemble and replace the sleeve, which increases the probability of accidents. In view of the above problems, a printing press water roller fixing sleeve that can be quickly replaced is proposed. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0020] Please see all instructions drawings:

[0021] A printing press water roller fixed sleeve, comprising a printing press water roller assembly, wherein a sleeve 6 is sleeved in the printing press water roller assembly, wherein an internal threaded hole 1 is provided in the sleeve 6, wherein a through hole 2 is provided at the bottom of the sleeve 6 corresponding to the internal threaded hole 1, wherein a rubber plug 3 is provided in the through hole 2, wherein the rubber plug 3 is interference fit with the through hole 2, wherein the through hole 2 can maintain the internal and external air pressure balance of the sleeve 6, and the rubber plug 3 can maintain the seal before replacement;

[0022] From the above description, it can be seen that the improved water stick fixed sleeve 6 is processed with an 8mm internal threaded hole 1 at the bottom of the inner hole. In this way, when the sleeve 6 needs to be replaced, it is only necessary to use a pin puller to connect the sleeve 6 with an 8mm screw rod, pull the broken sleeve 6 out from the inner side and install it back to the original position. There is no need to disassemble the equipment casing and connecting parts. The replacement time is 1 hour, reducing the risk of disassembling the transmission side.

[0023] As a technical optimization solution of the utility model, the shaft sleeve 6 is evenly and fixedly connected with anti-slip teeth 4;

[0024] It can be seen from the above description that the anti-slip teeth 4 can increase the friction between the shaft sleeve 6 and the pin puller, thereby improving the working efficiency.

[0025] As a technical optimization solution of the utility model, the diameter of the internal threaded hole 1 is 8 mm;

[0026] From the above description, we can see that in the Luer thread standard, the size of 8mm inner diameter is of great significance. This size of thread is widely used in mechanical equipment, instrumentation, electronic equipment and other industries.

[0027] As a technical optimization solution of the utility model, a groove 5 is provided on one side of the sleeve 6 close to the through hole 2, a connecting plastic part 7 is fixedly connected in the groove 5, and the other end of the connecting plastic part 7 is fixedly connected to the rubber plug 3;

[0028] From the above description, it can be known that the connecting plastic part 7 can control the connection of the rubber plug 3 to prevent it from falling off and affecting the normal operation of external components.

[0029] Working principle:

[0030] The improved water stick fixed shaft sleeve 6 is processed with an 8mm internal threaded hole 1 at the bottom of the inner hole. In this way, when the shaft sleeve 6 needs to be replaced, it is only necessary to use a pin puller to connect the shaft sleeve 6 with an 8mm screw rod, pull the broken shaft sleeve 6 out from the inner side and install it back to the original position. There is no need to disassemble the equipment casing and connecting parts. The replacement time is 1 hour, reducing the risk of disassembling the transmission side.

[0031] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
