Description

Technical Field

[0001] The utility model relates to a bearing seat and a roller device used for carrying tool equipment such as coating equipment. Background Art

[0002] Coating machines are primarily used for surface coating production of films such as glass fiber or carbon fiber. This involves applying a layer of adhesive, coating, paint, or ink to a roll of film, drying it, and then rewinding it. During the coating process, a feeding mechanism propels the film, such as glass fiber or carbon fiber, forward. Multiple rollers with different functions are used throughout the process to facilitate feeding, remove excess adhesive, coating, paint, or ink, and perform cooling.

[0003] Conventional roller assemblies often utilize a bearing block to secure the roller assembly in the desired position. However, if impregnating liquids, such as glue, coatings, paint, or ink, enter the bearing block and are not properly drained, the roller unit can experience malfunction, leading to quality issues such as uneven coating and wrinkles. In such cases, personnel are often forced to repair or replace the bearing block. This replacement requires repositioning, which is time-consuming and cumbersome, and increases labor costs.

[0004] In summary, the inventors of the present invention have considered and designed a bearing seat and roller device in order to improve the shortcomings of the existing technology and thereby promote its implementation and utilization in the industry. Utility Model Content

[0029] Please also refer to Figures 1 to 3 .in, Figures 1 to 3 The following are the exploded, assembled, and cross-sectional views of the bearing seat of the present invention. As shown in the figure, the bearing seat of the present invention is primarily used to support a roller unit 21 of a tool device such as a coating device or a conveying device. The roller unit 21 has a connecting shaft 22 at each end.

[0030] As shown in the figure, the bearing seat 1 of the present invention mainly includes a bearing 11 and a base 12. The bearing 11 can be a bearing well-known or commonly used by those skilled in the art to which the present invention relates, such as a precision ball bearing; the bearing 11 is fixed to the connecting shaft 22. The base 12 includes a first base 131 and a second base 132 that are removably assembled into a single unit. The first base 131 and the second base 132 each have a semi-accommodation groove 14. When the first base 131 and the second base 132 are assembled, the two semi-accommodation grooves 14 form a bearing chamber 15 that can just accommodate the bearing 11. One of the first base 131 and the second base 132 has a connecting groove 16; in this embodiment, the second base 132 is used as an example. The connecting groove 16 connects the first base 131 or the second base 132 in the radial direction to the semi-accommodation groove 14, and the connecting groove 16 corresponds to the direction of gravity.

[0031] It is worth mentioning that the connecting groove 16 is in the shape of an elongated ellipse. Incidentally, the axial direction is perpendicular to the direction of gravity, and the radial direction is perpendicular to the axial direction, and has an angle of any angle with the direction of gravity.

[0032] Specifically, the semi-accommodation groove 14 is substantially semicircular, and its diameter corresponds to the diameter of the bearing 11 , so that the bearing accommodation chamber 15 is substantially circular, and its diameter corresponds to the diameter of the bearing 11 .

[0033] The semi-accommodation groove 14 is provided with a semi-annular positioning groove 17, and the bearing 11 is provided with a semi-annular positioning protrusion 18 corresponding to the semi-annular positioning groove 17. Preferably, the bearing 11 is provided with the semi-annular positioning groove 17, and the semi-accommodation groove 14 is provided with the semi-annular positioning protrusion 18 corresponding to the semi-annular positioning groove 17. In this way, the bearing 11 can be properly and securely disposed in the bearing chamber 15.

[0034] In addition, the first base 131 and the second base 132 can be made of metal. Except for the connecting groove 16, their other structures are substantially the same. Specifically, the first base 131 and the second base 132 include a semi-disc portion 133, a semi-axial column portion 134, and two radial portions 135. The semi-axial column portion 134 is located at the center point of the semi-disc portion 133 and extends in the axial direction. The two radial portions 135 are symmetrically arranged about the center point of the semi-disc portion 133 and extend in the axial direction. In the embodiment, the extension direction of the radial portion 135 forms a 90-degree angle with the direction of gravity.

[0035] The semi-accommodating groove 14 is provided on the semi-axial column portion 134. The semi-disc portion 133 is provided with a plurality of fixing holes 136, which allow the user to use the fixing holes 136 to set the bearing seat 1 at a desired predetermined position. The two radial portions 135 are respectively provided with a combination portion 137; preferably, the combination portion 137 can be a through hole and a screw hole. For example, the combination portion 137 of the first base 131 is a through hole, while the combination portion 137 of the second base 132 is a screw hole. Thus, the user can use a bolt passing through the through hole and locking it in the screw hole to stably combine the first base 131 and the second base 132.

[0037] As shown in the figure, the roller device 2 of the present invention includes a roller unit 21 and two bearing seats 1; wherein, the bearing seat 1 is as described in the above embodiment, that is, in this embodiment, the components with the same component symbols have the same or similar configurations and operations as the above embodiment, and the same or similar parts will not be repeated here.

[0038] The roller unit 21 has two connecting shafts 22 facing each other. Two bearing seats 1 are mounted on the connecting shafts 22. Preferably, the connecting shafts 22 are provided with stoppers 23 and retaining ring grooves 24 at intervals. The roller assembly 2 also includes two retaining rings 25. When the bearing 11 is fixed to the connecting shaft 22 and positioned between the stoppers 23 and the retaining ring grooves 24, the retaining rings 25 are removably mounted in the retaining ring grooves 24.

[0039] Furthermore, the stopper portion 23 may be a stepped, protruding structure, or the like, while the retaining ring groove 24 may be a groove surrounding the connecting shaft 22. The retaining ring 25 may be a C-shaped retaining ring, which is well known or commonly used by those skilled in the art. In this manner, the bearing housing 1 can be stably fixed to each connecting shaft 22.

[0040] The bearing seat of the present invention is configured with the above-mentioned predetermined structure. When the bearing seat is infiltrated with an impregnating liquid such as glue, coating, paint or ink, the impregnating liquid can be discharged through the connecting groove, thereby improving the problem of the bearing seat not running smoothly due to the infiltration of the impregnating liquid.
