Description
Technical Field
The utility model relates to a equipment for packing accessory technical field, concretely relates to but quick replacement's drive roller.
Background
Referring to fig. 1, a conventional driving roller is composed of a driving roller shaft (1), an iron core (2) and an encapsulation (3), wherein two ends of the driving roller shaft (1) are installed on a driving roller seat through two bearing seats, the driving roller is driven by a motor to rotate, and the total length of the driving roller is generally about 1.2 m. The traditional driving roll shaft (1) and the iron core (2) are generally welded together and are an integral body.
Along with the use of equipment, the rubber coating can wear and tear, just at this moment need change the drive roller, because installation space is limited, need tear down drive roller and bearing frame together, it is more troublesome, and because of whole weight is heavier, it is also inconvenient to install.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a but quick replacement's drive roller to prior art's defect and not enough.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a but quick replacement's drive roller, includes driving roller axle, iron core and rubber coating, the rubber coating covers at the iron core surface, and its innovation point lies in: a square shaft is arranged at the tail end of the driving roll shaft, a square hole is formed in the iron core, and the square shaft is embedded into the square hole and matched with the square hole; the iron core is provided with a square shaft, the tail end of the square shaft is provided with a threaded hole, the iron core is provided with a counter bore, the counter bore and the square hole are located on the same central shaft, a threaded through hole is formed between the counter bore and the square hole, the threaded through hole is connected with a fastening bolt in a threaded mode, and the fastening bolt is fixedly connected with the threaded hole at the tail end of the square shaft.
Furthermore, a spring is sleeved on the fastening bolt.
Further, the square shaft is in clearance fit with the square hole.
After the structure is adopted, the utility model discloses beneficial effect does:
the utility model has simple structure, reasonable design and convenient use; the utility model discloses a setting can dismantle the iron core and the driving roller axle of connection, when the drive roller is changed to needs, only need loosen locking bolt, can lift the iron core off from the driving roller axle, just can change the rubber coating position, practices thrift the maintenance time greatly.
Drawings
FIG. 1 is a schematic diagram of a conventional structure;
fig. 2 is a schematic structural diagram of the present invention.
Description of reference numerals:
the device comprises a driving roll shaft 1, an iron core 2, a rubber coating 3, a square shaft 4, a square hole 5, a threaded hole 6, a counter bore 7, a threaded through hole 8, a fastening bolt 9 and a spring 10.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 2, the driving roller capable of being replaced rapidly comprises a driving roller shaft 1, an iron core 2 and an encapsulation 3, wherein the encapsulation 3 covers the surface of the iron core 2, a square shaft 4 is arranged at the tail end of the driving roller shaft 1, a square hole 5 is formed in the iron core 2, and the square shaft 4 is embedded in the square hole 5 and matched with the square hole 5; the tail end of the square shaft 4 is provided with a threaded hole 6, the iron core 2 is provided with a counter bore 7, the counter bore 7 and the square hole 5 are located on the same central shaft, a threaded through hole 8 is formed between the counter bore 7 and the square hole 5, the threaded through hole 8 is in threaded connection with a fastening bolt 9, and the fastening bolt 9 is fixedly connected with the threaded hole 6 at the tail end of the square shaft. Specifically, the driving roller shaft 1 is inserted into the square hole 5 through the square shaft 4 for limiting installation, the fastening bolt 9 is screwed into the threaded hole 6 to complete the fixed installation of the driving roller shaft 1 and the iron core 2, when the rubber coating part needs to be replaced, the iron core 2 can be detached from the driving roller shaft 1 only by loosening the locking bolt 9, the rubber coating 3 part can be replaced, and the maintenance time is greatly saved; the use of the counter bore 7 can prevent the fastening bolt 9 from being exposed.
In this embodiment, the fastening bolt 9 is sleeved with a spring 10. The spring 10 is pressed by the fastening bolt 9 and abuts against the nut of the fastening bolt 9, so that the fastening bolt 9 is in a tightened state and the fastening bolt 9 is prevented from loosening.
In this embodiment, the square shaft 4 is in clearance fit with the square hole 5, so as to ensure that the square shaft 4 and the square hole 5 have a high degree of fit.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
