Description

Technical Field

[0001] The utility model relates to the technical field of air expansion shafts, in particular to a nylon air expansion sleeve. Background Art

[0002] The inflatable shaft is a module that fixes rotating cylindrical materials by inflating them. The size of the inflatable shaft is fixed. According to customer needs and the inner diameter of the material, the inflatable sleeve can be put on the inflatable shaft to meet the inflatable needs in different situations and occasions. Today's inflatable sleeves have a complicated structure, are difficult to process, and are heavy, which makes the inflatable shaft under great pressure and greatly reduces the life of the machine.

[0003] In view of the above situation, it is necessary to improve the existing nylon inflatable sleeve structure so that it can meet the current needs for the use of nylon inflatable sleeves. Utility Model Content

[0004] The utility model aims to solve the above problems and designs a nylon inflatable sleeve.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is a nylon inflatable sleeve, comprising an inflatable sleeve body, a spring arranged on the inflatable sleeve body, and a fixing piece arranged on the inflatable sleeve body, wherein the spring is fixedly installed on the inflatable sleeve, and the fixing piece is arranged in the inflatable sleeve body and fixedly connected thereto.

[0006] As a further supplement to the technical solution, a plurality of protrusions are arranged in a circumferential array on the inflatable sleeve body.

[0007] As a further supplement to the technical solution, the inflatable sleeve body is composed of a first body, a second body, and a third body connected together. The first body, the second body, and the third body are respectively connected by fixing parts, and the spring is respectively arranged on the first body, the second body, and the third body.

[0008] As a further supplement to the technical solution, the first body, the second body and the third body are arc-shaped and the cross-section of the connection combination of the three is circular.

[0009] As a further supplement to the technical solution, the fixing member is respectively connected to the first body, the second body and the third body by screws.

[0010] As a further supplement to the technical solution, the inflatable sleeve is made of nylon.

[0011] Its beneficial effects lie in that it is composed of three sections, and a fixing piece is used to limit the expansion sleeve. The spring can fix the expansion sleeve to ensure the stability of the expansion sleeve, and it is made of nylon material, which can reduce the weight of the product.

[0016] In order to make the technical solution more clear to those skilled in the art, Figure 1 -3 Detailed description of the technical solution of the utility model:

[0017] A nylon inflatable sleeve comprises an inflatable sleeve body 1, a spring 2 arranged on the inflatable sleeve body 1, and a fixing part 3 arranged on the inflatable sleeve body 1. The spring 2 is fixedly installed on the inflatable sleeve, and the fixing part 3 is arranged in the inflatable sleeve body 1 and fixedly connected thereto. The spring 2 can fix the inflatable sleeve, so that subsequent work can proceed normally.

[0018] Among them, there are several protrusions 4 in a circular array on the inflatable sleeve body 1, and grooves are provided between adjacent protrusions 4, which can provide a larger margin space for the inflatable sleeve itself, reduce the weight of the inflatable sleeve, and extend the life of the machine. The protrusions 4 can facilitate the inflatable sleeve to better expand the material roller, and a hollow device is made on the inflatable sleeve body 1 to reduce the pressure on the inflatable shaft 8 and greatly extend the life of the machine.

[0019] The structure of the inflatable sleeve body 1 will be described in detail below. The inflatable sleeve body 1 is composed of a first body 5, a second body 6, and a third body 7. The first body 5, the second body 6, and the second body 6 are respectively connected by a fixing member 3. The spring 2 is respectively arranged on the first body 5, the second body 6, and the third body 7. Furthermore, the first body 5, the second body 6, and the third body 7 are arc-shaped and the cross-section of the connection combination of the three is circular, which is convenient for installation and processing, and can further reduce labor costs. Preferably, the fixing member 3 is respectively connected to the first body 5, the second body 6, and the third body 7 by screws, which is easy to operate, has a good fixing effect, and is easy to replace.

[0020] Among them, the inflatable sleeve is made of nylon material, which can reduce the overall weight of the inflatable shaft 8 module and extend the life of the machine.

[0021] The working principle of the utility model will be described in detail below: the inflatable sleeve is inserted into the inflatable shaft 8 with the same inner diameter of 6 inches, the material roller is inserted on the outer diameter of the inflatable sleeve, and then the inflatable shaft 8 is ventilated to prop up the inflatable sleeve, wherein the inflatable sleeve props up the material roller to a fixed limit position for subsequent processing.

[0022] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
