Description

Technical Field

[0001] The utility model relates to the technical field of cotton openers, in particular to a cotton feed roller bearing seat fixing structure of a cotton opener. Background Art

[0002] The cotton blower is one of the important equipment in the textile industry. It is mainly used to clean impurities and bad fibers in cotton and improve the quality and processing efficiency of cotton. The cotton blower is usually composed of multiple cleaning units, including cotton opening, cotton cleaning, impurity removal, mixing and other links. In the cotton opening link, the cotton is fed into the cotton opener. After being cut by high-speed rotating blades and airflow, large impurities and lumps in the cotton are opened and turned into smaller fiber blocks.

[0003] As the cotton blower unit is used for a longer period of time, some components are worn and aged. To ensure the stable operation of the unit and extend its service life, timely maintenance is required. During the operation of a single machine, the bearing seat of the cotton feed roller of the existing FA1115 fine cotton opener is fixed on the wall panel of the machine itself. However, during the vibration of the equipment and the wear of the bearing, the fixing hole between the fixing point of the bearing seat and the wall panel of the machine gradually wears and expands, making it impossible to fix it effectively. To solve this problem, thicker bolts have to be used for fixing. However, this practice will gradually damage the wall panel and may eventually make it irreparable.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a fixing structure for the bearing seat of the cotton feed roller of a cotton opener. Utility Model Content

[0016] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0017] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution for the fixed structure of the bearing seat of the cotton feed roller of the cotton opener: comprising a back plate 1, which is the basis of the entire fixed structure. A rubber pad 13 is arranged on the surface of the back plate 1. The rubber pad 13 not only plays a role in buffering and shock absorption, but more importantly, it provides a stable support for the installation of the bearing seat 2. On the outer side of the rubber pad 13, the bearing seat 2 is accurately placed.

[0018] In order to ensure a firm connection between the bearing seat 2 and the back plate 1, a plurality of fastening holes 11 are provided through the back plate 1. The fastening holes 11 and the bearing seat 2 are fixed by bolts 12. The use of the bolts 12 not only simplifies the installation process, but also provides a strong fastening force, effectively preventing the bearing seat 2 from loosening during operation.

[0019] The fastening holes 11 on the back plate 1 are not only for matching with the bolts 12, but also connected to the machine wall plate. The double connection design further enhances the stability of the entire structure.

[0020] A plurality of positioning columns 3 are provided on both sides of the bearing seat 2. These positioning columns 3 are not only connected to the back plate 1, but also abut against the bearing seat 2, thereby ensuring the stability of the bearing seat 2 in the horizontal direction. In order to further enhance the positioning effect of the positioning columns 3, a positioning groove 14 is designed between two vertically distributed positioning columns 3. The positioning columns 3 can be inserted into the positioning groove 14 more accurately, thereby realizing the precise positioning of the bearing seat 2.

[0021] A movable block 32 is installed on the end surface of each positioning column 3. These movable blocks 32 form a sliding fit with the positioning groove 14, so that the positioning column 3 can be fine-tuned within a certain range. Springs 33 are installed between the relative movable blocks 32. The setting of the spring 33 not only provides elasticity, but also ensures the stability and durability of the positioning column 3.

[0022] In order to further improve the sealing and wear resistance of the bearing seat 2, the outer wall of each positioning column 3 is sleeved with a rubber sleeve 31. These rubber sleeves 31 not only form a tight contact with the outer wall of the bearing seat 2, but also play a role in reducing friction and preventing wear.

[0023] In summary, the fixing structure of the bearing seat realizes the stable installation and precise positioning of the bearing seat.

[0024] In this embodiment, the bearing seat 2 is inserted between multiple positioning columns 3, the positioning columns 3 are squeezed, the rubber sleeve 31 is resisted therefrom, acts on the movable block 32, and stretches the spring 33 to complete the positioning, and then the bearing seat 2 and the back plate 1 are assembled by bolts 12, and finally the back plate 1 and the machine wall panel are assembled by bolts 12. This solution indirectly fixes the bearing seat to the main machine wall panel, while reducing vibration and bearing wear, and will not directly cause damage to the main machine wall panel, nor will it gradually expand the fixing hole of the main machine wall panel.

[0025] The working principle and use process of the utility model: After the utility model is installed, it works according to the above implementation method until all the working steps are completed.
