Description

TECHNICAL FIELD

[0001] The present invention relates to a bearing set and roller system for a saturator, in particular, a bearing set and roller system for use in a saturator that operates in a bath. BACKGROUND

[0002] In the technical field of saturating technology (also known as coating technology), a conveying device (roller) is used to drive a base fabric for processing. If there is a step of impregnating the base fabric during the processing, such as FIG. 1A As shown in FIG. 1, since the glue tank B is filled with liquid (e.g., glue G), it is usually arranged at the bottom end of the conveying device, so that the base fabric (not shown in the figure) laid on the roller 10 can rotate upward along the outer periphery of the last roller 10 after being soaked in the glue tank B. Therefore, the roller 10 arranged at the end of the conveying device must operate in the glue G, provide a path for the rotation of the base fabric, and tension the base fabric so that it can be driven by the driven roller 10.

[0003] When the bearing set 20 supporting the roller 10 is soaked in the glue tank B, the liquid glue G will invade into the inside of the bearing set 20. When the roller 10 is removed from the glue tank B for removing the processed base fabric or for maintenance or repair of the conveying device, for example FIG. 1B As shown in FIG. 2, the glue G can solidify and stick to the inside of the bearing set 20, so that the bearings in the bearing set 20 cannot continue to be used because they cannot rotate or slide smoothly. The conventional solution to this technical problem is to replace the new bearing set 20 before the next operation to ensure that the roller 10 can operate normally, but this also causes waste of parts and increase in production cost.

[0004] Therefore, there is an urgent need for an improved bearing set and roller system that can prevent the bearing set from being damaged by the invasion of liquid or semi-liquid glue. SUMMARY

[0005] To solve the above problems, the present invention provides a bearing set for a saturator, which comprises a bearing seat and a bearing. The bearing seat has a channel formed therein. The bearing is arranged in the channel and is used to connect a roller. A fluid passage is formed in the bearing seat for flowing fluid therethrough and spraying the fluid towards the bearing, so that the bearing driven by the rotating roller is cleaned by the fluid when rotating.

[0006] The fluid passage in the bearing set provided by the present invention comprises an upstream section and a downstream section. The upstream section forms a fluid inlet; the downstream section is located downstream of the upstream section and forms a fluid outlet with an opening facing the bearing, wherein the flow area of the downstream section is smaller than that of the upstream section.

[0007] The first extension direction of the upstream section and the second extension direction of the downstream section in the bearing set have an included angle ranging from 60 to 120 degrees.

[0008] The bearing set provided by the present application has a space between the fluid outlet of the fluid through hole and the bearing in the passage.

[0009] The bearing set provided by the present application further comprises a cover detachably connected to the bearing seat and forming the passage for arranging the bearing with the bearing seat.

[0010] The bearing seat in the bearing set provided by the present application forms an exhaust through hole for exhausting the fluid splashed from the fluid through hole to the bearing from the passage to the outside of the bearing seat.

[0011] The exhaust through hole in the bearing set provided by the present application is arranged in the bearing seat at a side opposite to the fluid through hole with respect to the longitudinal axis of the bearing seat.

[0012] The bearing seat in the bearing set provided by the present application comprises a first section and a second section. The first section is formed with a first opening. The second section is integrally connected to the first section and forms the passage with the first section. The second section is formed with a second opening for connecting the roller. The first cross section of the first part of the passage of the first section gradually expands from the connection with the second section towards the first opening, so that the surface of the first part forms a truncated cone shape.

[0013] The second part of the passage of the second section in the bearing set provided by the present application has a constant second cross section for accommodating the bearing.

[0014] To solve the above problems, the present application further provides a roller system for a saturator, which comprises a support plate having a plurality of fluid passages, a fluid supply unit and the bearing set as described above. The plurality of bearing sets are arranged on the support plate for connecting and supporting the rollers. The fluid through holes of the plurality of bearing seats are respectively in fluid communication with the plurality of fluid passages, and the fluid supply unit supplies fluid into the fluid through holes through the plurality of fluid passages.

[0015] The present application at least by means of the technical feature of "a fluid passage hole is formed in the bearing seat for flowing fluid therein and splashing fluid toward the bearing", when the bearing seat is immersed in glue, the bearing is constantly flushed by fluid such as solvent to avoid the glue to stay in the bearing. After the bearing set leaves the glue bucket groove with the roller system, the bearing still has a certain amount of lubricating oil or grease, so that new bearing set is not needed to be replaced before the next operation of the roller system, achieving the advantageous effects of reducing parts waste, reducing production cost and improving production efficiency.

It is understood by those skilled in the art that the present application is not limited to the following embodiments, and the aspects and details of the embodiments can be changed, modified or replaced without departing from the spirit and scope of the present application defined in the claims. Therefore, the interpretation of the claims of the present application is not limited by the content described in the following embodiments.

[0034] As shown in FIG. 1A and 1B , which respectively show a schematic diagram of rollers 10 of a roller system R according to an embodiment of the present application immersed in a glue vat B and a schematic diagram of the roller system R and the glue vat B separated according to an embodiment of the present application. The roller system R according to an embodiment of the present application comprises a plurality of rollers 10 and a bearing set 20 connected to both ends of each roller 10 in two groups, and when the plurality of rollers 10 are supported by a support plate 30 and moved along a descending direction D1 towards the inside of the glue vat B by means of a lifting device 40 connected to and driving the support plate 30, at least part of the rollers 10 are immersed in the glue G to perform the immersion operation, as shown in FIG. 1A , the base fabric (not shown in the figure) is attached to the shaft 12 of the roller 10, and the base fabric is driven to move along with the rotation of the roller 10 by means of the tension between the roller 10 and the base fabric. The base fabric is transported and immersed in the glue G of the glue vat B under the driving of the roller set 10, and then the transport direction is reversed upwards by about 180 degrees by attaching the base fabric to the surface of the shaft 12 of the roller 10 arranged at the bottom of the roller set, and then the base fabric is separated from the glue G and the glue vat B.

[0035] As shown in FIG. 1B , according to an embodiment of the present application, when it is necessary to maintain or maintain, for example, the conveying device including the plurality of rollers 10, the lifting device 40 or the support plate 30, or in order to adjust the relative position of the base fabric on the roller 10, the lifting device 40 lifts the roller set including the plurality of rollers 10 along the lifting direction D2 through the support plate 30, and the rollers 10 immersed in the glue G are removed from the glue vat B. As shown in FIG. 1A and 1B , according to an embodiment of the present application, the trailer device C can be used to carry the glue vat B, and the mobility of the trailer device C is beneficial to the handling of the glue vat B, including replacing the glue G, moving to replace other glue vat, etc.

[0036] AsFIG. 1A and FIG. 1B As shown, a roller system R for an impregnation machine according to one embodiment of the present invention includes a support plate 30, multiple bearing assemblies 20, a roller 10, and a fluid supply unit (described in detail below). The support plate 30 has multiple fluid channels, and the multiple bearing assemblies 20 are disposed on the support plate 30 to connect and support the roller 10. The multiple bearing assemblies 20 according to the present invention will be described in detail below. The fluid through-holes of the multiple bearing seats are respectively in fluid communication with the multiple fluid channels, and the fluid supply unit supplies fluid to the fluid through-holes through the multiple fluid channels (described in detail below).

[0037] like FIG. 2A 、 2B and 2C, which respectively show a partial cross-sectional view of a bearing assembly connected to a roller according to one embodiment of the present invention, FIG. 2A A magnified view of part A and FIG. 2A Schematic diagram of the separation after the components are separated. The bearing assembly for the impregnation machine according to one embodiment of the present invention includes a bearing seat 21, a bearing 22 and a cover 23. The bearing seat 21 forms a channel 210 inside thereof for accommodating the bearing 22, and when the connecting end 11 of the roller 10 is inserted into the opening of the bearing seat 21 for accommodating the bearing 22, the connecting end 11 can be inserted into the bearing 22, so that the roller 10 can be firmly supported by the bearing 22 and can rotate or roll smoothly relative to the bearing seat 21 when rotating. The bearing 22 is configured to be connected to the connecting end 11 of the roller 10 and is arranged in the channel 210. A fluid through hole 213 is formed in the bearing seat 21, which is used to allow the fluid to flow therein and guide the fluid to splash toward the bearing 22, so that the bearing driven by the rotating roller 10 is cleaned or flushed by the fluid when rotating.

[0038] like FIG. 2A 、 FIG. 2C or FIGS. 3A-3C As shown, the bearing seat 21 according to one embodiment of the present invention may include a first section 211 and a second section 212. FIG. 3B As shown, the first section 211 may have a first opening 211A formed at its end, which is open to the outside. The first section 211 may include an extension section 211B and a flange section 211C, depending on its outer contour. The second section 212 of the bearing seat 21 may have a second opening 212A formed at its end, opposite to the first opening 211A. This opening 212A is open to the outside and is used to connect to the connecting end 11 of the roller 10. The second section 212 of the bearing seat 21 may be integrally connected to the first section 211 and internally form a channel 210.

[0039] like FIGS. 2A-2CAs shown, the fluid through hole 213 according to one embodiment of the present invention may include an upstream section 213A, a downstream section 213B and a fluid outlet 213C, wherein the upstream section 213A forms a fluid inlet 213D at its outward opening. FIG. 2C As shown, the fluid through hole 213 of the bearing seat 21 can be in fluid communication with the fluid channel 32 of the support plate 30 through the fluid inlet 213D, and then the fluid is guided from the fluid supply unit to the fluid through hole 213 through the fluid channel 32. FIG. 2B As shown, the upstream section 213A extends along the first extension direction E1, which is substantially the same as the direction in which the fluid channel 32 of the support plate 30 extends, and the upstream section 213A and the fluid channel 32 have substantially the same flow area, so that the fluid can enter the bearing seat 21 from the support plate 30 stably and with uniform pressure, avoiding installation difficulties caused by fluid leakage or changes in fluid pressure.

[0040] To redirect the fluid through-hole 213 so that the fluid ultimately splashes onto the bearing 22 for a cleaning effect, the downstream section 213B of the fluid through-hole 213, located downstream of the upstream section 213A, can extend along a second extension direction E2. The second extension direction E2 is different from the first extension direction E1. The angle α between the first extension direction E1 of the upstream section 213A and the second extension direction E2 of the downstream section 213B is preferably between 60 and 120 degrees, more preferably between 70 and 100 degrees, or even more preferably 90 degrees. The flow area of ​​the downstream section 213B may be smaller than the flow area of ​​the upstream section 213A. For example, the flow area of ​​the downstream section 213B is approximately 1 / 5 to 1 / 2 of the flow area of ​​the upstream section 213A, preferably 1 / 4 to 1 / 3, and more preferably 1 / 4. This allows the fluid to increase its flow rate after entering the downstream section 213B from the upstream section 213A due to the smaller flow area, thereby giving the fluid sufficient pressure to effectively splash on the bearing 22 when it is ejected from the fluid outlet 213C formed in the downstream section 213B.

[0041] like FIG. 2A As shown, according to one embodiment of the present invention, the fluid outlet 213C can be formed on the end surface of the flange section 211C of the first section 211 of the bearing seat 21, and the fluid pressurized by the downstream section 213B with a smaller flow area is sprayed toward the second section 212 of the bearing seat 21 and toward the bearing 22. FIG. 2B As shown, the fluid does not spray toward the bearing 22 immediately after leaving the fluid outlet 213C, but first passes through the space S in the channel 210 between the fluid outlet 213C of the fluid through hole 213 and the bearing 22 before being sprayed toward the bearing 22.

[0042] More specifically, if FIGS. 3A-3B As shown, they respectively show the front view of the bearing seat according to one embodiment of the present invention, FIG. 3AFigure 2A is a cross-sectional end view of the bearing housing 21 and a side view of the bearing set 20 according to an embodiment of the present application. The passage 210 of the bearing housing 21 can be divided into a first portion 210A and a second portion 210B according to different cross-sections, which can be cross-sections along a central longitudinal axis L perpendicular to the extending direction of the bearing housing 21. The first cross-section Al of the first portion 210A is smaller than the second cross-section A2 of the second portion 210B.

[0043] As shown in Figure 2B, the second portion 210B of the passage 210 of the second section 212 according to an embodiment of the present application (see also Figure 2A) can have a substantially constant second cross-section A2, so that the second portion 210B of the passage 210 can accommodate the bearing 22. The second cross-section A2 has a diameter substantially consistent with the outer cylindrical profile diameter of the bearing 22, so that the bearing 22 can be accommodated in the second portion 210B of the passage 210, and the bearing 22 can be securely clamped or snapped in the second portion 210B of the passage 210 of the bearing housing 21 when the roller 10 is rotating. FIG. 2A FIG. 3B As shown in Figure 2B, the second portion 210B of the passage 210 of the second section 212 according to an embodiment of the present application (see also Figure 2A) can have a substantially constant second cross-section A2, so that the second portion 210B of the passage 210 can accommodate the bearing 22. The second cross-section A2 has a diameter substantially consistent with the outer cylindrical profile diameter of the bearing 22, so that the bearing 22 can be accommodated in the second portion 210B of the passage 210, and the bearing 22 can be securely clamped or snapped in the second portion 210B of the passage 210 of the bearing housing 21 when the roller 10 is rotating.

[0044] As shown in Figure 2C, the fluid through hole 213 according to an embodiment of the present application can be disposed in the extension section 211B and the flange section 211C of the bearing housing 21. More specifically, the fluid inlet 213D of the fluid through hole 213 can be formed in the outer wall of the extension section 211B, the upstream section 213A, the transition section connecting the upstream section 213A and the downstream section 213B, and a portion of the downstream section 213B are formed in the extension section 211B; and the remaining portion of the downstream section 213B is formed in the flange section 211C of the bearing housing 21, and finally the fluid outlet 213C is formed in the side wall of the flange section 211C (see Figure 2D). In this way, the fluid through hole 213 for taking fluid from the fluid supply unit through the support plate 30 is disposed in the extension section 211B and the flange section 211C of the bearing housing 21 which is securely connected to the support plate 30, as shown in Figure 2D. FIG. 2A FIG. 2B As shown in Figure 2B, the second portion 210B of the passage 210 of the second section 212 according to an embodiment of the present application (see also Figure 2A) can have a substantially constant second cross-section A2, so that the second portion 210B of the passage 210 can accommodate the bearing 22. The second cross-section A2 has a diameter substantially consistent with the outer cylindrical profile diameter of the bearing 22, so that the bearing 22 can be accommodated in the second portion 210B of the passage 210, and the bearing 22 can be securely clamped or snapped in the second portion 210B of the passage 210 of the bearing housing 21 when the roller 10 is rotating. FIG. 2A ​​As shown, the extension section 211B can be inserted into the through-hole of the support plate 30, and the flange section 211C can be abutted against the wall of the support plate 30. The bearing seat 21 is then fixed to the support plate 30 using fixing elements such as screws, bolts, and nuts. In other words, the extension section 211B and flange section 211C of the bearing seat 21 can be directly connected to the support plate 30, without being subjected to additional shear stress when the roller 10 drives the base fabric. In this environment, the arrangement of the fluid through-holes 213 in the extension section 211B and flange section 211C of the bearing seat 21 ensures that the fluid passage 32 receiving fluid from the support plate 30 is discharged with a certain fluid pressure, without affecting the stability of the connection between the bearing seat 21 and the support plate 30, and without causing fluid leakage due to structural looseness. Furthermore, a sufficient amount of fluid can be splashed onto the bearing 22, achieving an optimal cleaning effect.

[0045] According to one embodiment of the present invention, the bearing seat 21 further forms a discharge hole 214 for discharging the fluid splashed from the fluid hole 213 to the bearing 22 from the channel 210 to the outside of the bearing seat 21. Specifically, the discharge hole 214 can be arranged in the bearing seat 21 on the opposite side of the fluid hole 213 relative to the longitudinal axis L of the bearing seat 21. For example, FIG. 2A As shown in the figure, the fluid through-hole 213 can be arranged on the upper side of the longitudinal axis L of the bearing seat 21, while the discharge through-hole 214 can be arranged on the lower side of the longitudinal axis L of the bearing seat 21, that is, on the opposite side of the longitudinal axis L from the upper side of the fluid through-hole 213. This allows the fluid to be guided into the channel 210 in the bearing seat 21 through the through-hole 213 and flush the bearing 22, and then be guided into the discharge through-hole 214 on the other side, so that the fluid that has flushed the bearing 22 can be discharged outside the bearing seat 21 along the discharge through-hole 214.

[0046] More specifically, if FIG. 2A As shown, in one embodiment of the present invention, the position of the discharge through hole 214 can be arranged in the second part 210B of the channel 210 of the bearing seat 21. Since the second part 210B has a second cross-section A2 that is larger than the first cross-section A1 of the first part 210A, the inner wall surface of the second part 210B of the channel 210 is closer to the outer wall surface than the first part 210A, that is, it has a thin wall surface. Arranging the discharge through hole 214 in the second part 210B can help the fluid flow out of the channel 210 of the bearing seat 21 faster and more smoothly. For the purpose of the present invention of using fluid to flush the bearing 22 so that the bearing 22 is not adhered by glue, it is of great help to keep the fluid flowing in the channel 210. In the case of FIG. 2AIn an embodiment of the application as shown, the discharge hole 214 can be arranged on the lower side close to the ground surface, so that the fluid can be smoothly introduced into the discharge hole 214 and flow out of the passage 210 to the outside of the bearing housing 21 by the force of gravity.

[0047] As mentioned above, in order to make the fluid entering the passage 210 inside the bearing housing 21 flow out of the passage 210 to the outside of the bearing housing 21 smoothly, as shown in FIG. 2A 、 FIG. 2B and FIG. 3B , in another embodiment of the application, the first cross section A1 of the first portion 210A of the passage 210 of the bearing housing 21 can gradually expand from the connection with the second portion 210B towards the first opening 211A, so that the first portion 210A gradually expands from the inside to the outside of the first opening 211A, and the surface of the first portion 210A of the passage 210 of the bearing housing 21 forms a truncated cone shape. This makes the fluid splashed to the first portion 210A of the passage 210 after being introduced into the passage 210 inside the bearing housing 21 by the fluid hole 213 and flushing the bearing 22, flow out of the outside of the bearing housing 21 through the inclined surface 211D to the first opening 211A. The included angle β (as shown in FIG. 2B ) of the first portion 210A of the application according to another embodiment of the application with respect to the longitudinal axis L is in the range of 5 to 15 degrees, preferably 7 degrees.

[0048] According to yet another embodiment of the application, as shown in FIG. 4A 、 FIG. 4B and FIGS. 2A-2C , wherein FIG. 4A shows a front view of the cover 23 according to yet another embodiment of the application, FIG. 4B shows a bottom view of the cover 23 according to yet another embodiment of the application, the bearing set of the application can further comprise a cover 23 which is detachably connected to the bearing housing 21 and forms said passage 210 with the bearing housing 21 for arranging the bearing 22. In order to facilitate the inspection, cleaning or treatment of the bearing 22, as shown in FIG. 2C , the bearing set of the application can further comprise a cover 23 which can generally have a symmetrical configuration with the second section 212 of the bearing housing 21, for example both being semicylinders of 180 degrees, and be detachably connected to the notch 212B of the second section 212 of the bearing housing 21 as shown in FIG. 2C , form the second portion 210B of the passage 210 with the second section 212 to jointly accommodate the bearing 22 as shown in FIG. 2B , and form the second opening 212A with the second section 212 to connect the connecting end portion 11 of the roller 10 in the passage 210 as shown in FIG. 2A 、 FIG. 2A and FIG. 4BAs shown, the cover 23 is provided with a shoulder 231 inside the cover 23 to abut against the bearing 22 when the bearing 22 is received in the cover 23, so that the bearing 22 can be stably received in the second portion 210B of the passage 210. The cover 23 according to yet another embodiment of the present application can be connected to the bearing housing 21 by means of, for example, screws, bolts, nuts, screw holes, buckles, sliding grooves, or the like. In addition, in other embodiments of the present application, the cover 23 can be a semicylinder of less than 180 degrees, instead of a semicylinder of 180 degrees, in which case the notch 212B of the second section 212 of the bearing housing 21 can be designed to match the shape of the cover 23, so that the cover 23 can be connected to the second section 212 while still forming a complete cylinder with the second section 212. The use of a smaller cover 23 can increase the size of the portion integral with the entire bearing housing 21, which is beneficial to the stability and durability of the bearing housing 21.

[0049] According to one embodiment of the present application, as shown in FIG. 1, a bearing assembly 20 according to one embodiment of the present application is shown. The bearing assembly 20 includes a bearing housing 21 and a cover 23. The bearing housing 21 is provided with a passage 210 for receiving a bearing 22. The passage 210 is formed in the bearing housing 21 and includes a first portion 210A and a second portion 210B. The first portion 210A is provided with a plurality of bearing seats 21 for receiving the bearing 22. The second portion 210B is provided with a plurality of fluid through holes 213 for receiving fluid from a fluid supply unit (not shown in the figure). The cover 23 is provided with a shoulder 231 for abutting against the bearing 22 when the bearing 22 is received in the cover 23, so that the bearing 22 can be stably received in the second portion 210B of the passage 210. FIGS. 5A-5C FIGS. 5A-5C As shown in FIG. 2, a front view, a top view, and a side view of a support plate 30 according to one embodiment of the present application are shown, respectively. The support plate 30 according to one embodiment of the present application can be formed with a plurality of through holes for receiving a plurality of bearing housings 21. The bearing assemblies 20 can be connected by fluid channels 32. Specifically, the fluid channels 32 are formed in the support plate 30 and are staggered at a junction 33 to extend above each bearing assembly 20, so as to guide fluid into the fluid through holes 213 of the bearing seats 21 of each bearing assembly 20. A plurality of fluid supply inlets 31 can be formed at the edges of the support plate 30 to guide fluid from a fluid supply unit (not shown in the figure) into the fluid channels 32.
