[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0031] A bearing retainer drying device, the structure of which can be Figure 1-Figure 6As shown in the figure, in this embodiment, the bearing retainer drying device comprises: a processing box 1, a hot air blower 2 and a plurality of drying units, wherein the processing box 1 is used to provide a processing space for drying the retainer 7, the hot air blower 2 is used to form a circulating hot air flow inside the processing box 1, and the drying unit is used to carry the retainer 7 to be dried and guide the flow direction of the hot air, so as to facilitate the hot air to contact with the slots on the retainer 7.
[0032] Specifically, a partition 11 is provided inside the processing box 1, a drying cavity 12 is formed below the partition 11, and an air collecting cavity 13 is formed above the partition 11, and the air collecting cavity 13 is connected to the drying cavity 12 through an air collecting cutout 111 provided on the partition 11. The hot air blower 2 is provided outside the processing box 1, and the air inlet end of the hot air blower 2 is connected to the air collecting cavity 13 through an air inlet pipe 21. A plurality of mounting holes 121 for accommodating a drying unit should be provided on the side wall of the drying cavity 12, and the drying unit includes an air guide blind pipe 3 and a bearing seat 4, wherein the bearing seat 4 is movably provided in the mounting hole 121, a receiving hole 41 for accommodating the air guide blind pipe 3 is provided at the first end of the bearing seat 4, and a limiting plate 51 having an outer diameter greater than the inner diameter of the mounting hole 121 is provided at the second end of the bearing seat 4, and the limiting plate 51 is located outside the processing box 1. The air guide blind pipe 3 is provided inside the drying cavity 12, and the air guide blind pipe 3 is connected to the air outlet section of the hot air blower 2. When the hot air blower 2 is started, the hot air blower 2 can transport hot air into the air guide blind pipe 3, so that the hot air enters the drying unit to dry the retaining frame 7. At the same time, the hot air blower 2 can also extract the gas inside the gas collecting cavity 13 through the air inlet pipe 21, so that the gas in the drying cavity 12 flows into the gas collecting cavity 13 through the gas collecting incision 111, thereby forming a circulating flow of gas inside the processing box 1.
[0033] In order to conveniently accommodate the holder 7 to be dried, the embodiment is provided with a plurality of bearing holes for accommodating the holder 7 on the side wall of the bearing seat 4. Accordingly, in order to facilitate the hot air entering the drying unit to contact the holder 7 inside the bearing hole, a plurality of first air guide holes 31 evenly arranged along the axial direction of the air guide blind tube 3 should be provided on the side wall of the air guide blind tube 3, an air guide joint 43 is provided in each bearing hole, and a plurality of second air guide holes 431 are provided on the side wall of the air guide joint 43.
[0034] When in use, the staff should first pull the bearing seat 4 to the outside of the processing box 1 so that all the bearing holes are exposed to the drying cavity 12, providing a larger operating space for the loading of the retaining frame 7. Then the retaining frame 7 to be dried can be loaded into the bearing hole, and the bearing seat 4 can be pushed into the drying cavity 12. When the limit plate 51 fits the outer wall of the processing box 1, the air guide joints 43 inside the multiple bearing holes will be respectively connected to the multiple first air guide holes 31 on the air guide blind pipe 3. At this time, the hot air generated by the hot air blower 2 will be blown along the second air guide hole 431 to the slot of the retaining frame 7, thereby drying the retaining frame 7. When the drying is completed, the staff can pull the bearing seat 4 to the outside of the processing box 1 again. When all the bearing holes are exposed to the drying cavity 12, the bearing seat 4 can be rotated so that the bearing holes face the ground. At this time, the dried retaining frame 7 will be separated from the bearing hole under the action of gravity, thereby completing the rapid separation of the retaining frame 7 and the bearing seat 4.
[0035] Optionally, in order to prevent the bearing seat 4 from being separated from the processing box 1 when being pulled outside the processing box 1, a positioning plate 52 having an outer diameter greater than the inner diameter of the mounting hole 121 may be provided at the first end of the bearing seat 4. Accordingly, in order to prevent the presence of the positioning plate 52 from affecting the insertion depth of the bearing seat 4 into the processing box 1, a positioning groove for accommodating the positioning plate 52 may also be provided on the inner side wall of the processing box 1.
[0036] In addition, in order to prevent the bearing seat 4 from rotating abnormally during the drying process of the retaining frame 7, a limiting strip 511 may be provided at one end of the limiting plate 51 close to the bearing seat 4, and a limiting groove 122 for accommodating the limiting strip 511 may be provided on the inner side wall of the mounting hole 121. When the limiting plate 51 is in contact with the outer wall of the processing box 1, the limiting strip 511 will enter the limiting groove 122, thereby circumferentially limiting the bearing seat 4 and preventing the bearing seat 4 from rotating.
[0037] As an optional implementation of this embodiment, in order to facilitate the staff to move the support seat 4, an operating handle 45 may be provided at the end of the limit plate 51 away from the support seat 4, so that the staff can grasp it. In addition, in order to prevent the hot air inside the processing box 1 from flowing outward along the joint gap between the mounting hole 121 and the support seat 4, a sealing gasket (not shown in the figure) with an outer diameter larger than the inner diameter of the mounting hole 121 may be provided at the end of the limit plate 51 close to the support seat 4, so as to block the joint gap with the help of the sealing gasket.
[0038] Figure 5 This is an exploded view of the drying unit. Figure 6It is a cross-sectional view of the drying unit. As shown in the figure, in order to further improve the hot air guiding ability of the device and strengthen the drying effect of the area near the slot of the holder 7, the bearing hole may include a first constraint section 421, a baffle section 422 and a second constraint section 423 connected in sequence from top to bottom, wherein the inner diameters of the first constraint section 421 and the second constraint section 423 are equal, and an arc-shaped baffle surface is provided on the inner wall of the baffle section 422, and the opening of the arc-shaped baffle surface faces the air guide joint 43. When the holder 7 is placed in the bearing hole, the inner walls of the first constraint section 421 and the second constraint section 423 can constrain the position of the holder 7, and the hot air blown out along the second air guide hole 431 will contact the arc-shaped baffle surface on the baffle section 422 after passing through the slot of the holder 7. At this time, the arc-shaped baffle surface will cause the hot air to form a reflux inside the bearing hole, thereby increasing the contact probability of the hot air with the holder 7 and accelerating the drying speed of the holder 7.
[0039] In addition, the device is provided with an isolation net 6 inside the bearing hole. Figure 6 As shown, the isolation net 6 is located below the second air guide hole 431, and a water storage cavity is formed between the isolation net 6 and the bottom inner wall of the bearing hole. When the retainer 7 with a large amount of liquid attached to the surface enters the bearing hole, the isolation net 6 can support the retainer 7, so that the liquid separated from the retainer 7 enters the water storage cavity, thereby achieving separation of the retainer 7 and the liquid.
[0040] Correspondingly, in order to avoid liquid accumulation inside the water storage cavity, a drainage hole 44 connected to the water storage cavity may be further provided on the side wall of the support seat 4, so that the liquid inside the water storage cavity can be discharged to the outside in time.
[0041] In actual use, since multiple drying units are provided inside the device, the staff can use the device to perform drying work on multiple retainers 7 simultaneously. As another optional implementation of the present embodiment, the present device can also set the first air guide holes 31 in different drying units to different inner diameter specifications. Exemplarily, multiple drying units can be divided into three types of strong drying, ordinary drying and weak drying according to the inner diameter size of the first air guide holes 31, wherein the inner diameter of the first air guide holes 31 of the strong drying type drying unit is larger, the inner diameter of the first air guide holes 31 of the ordinary drying type drying unit is moderate, and the inner diameter of the first air guide holes 31 of the weak drying type drying unit is smaller. Since the inner diameter size of the first air guide holes 31 is proportional to the hot air flow rate blown to the retainer 7 per unit time, when the hot air blower 2 blows the hot air into each drying unit, the drying speed of the weak drying type drying unit, the ordinary drying type drying unit and the strong drying type drying unit will become faster in turn, and the staff can select the loading position of the retainer 7 according to actual needs, so that the retainer 7 can obtain a suitable drying effect.
[0042] The effects of the above scheme are described below:
[0043] This embodiment provides a bearing retainer drying device, which can guide hot air through a drying unit, so that the hot air can contact the retainer, thereby improving the drying effect of the retainer. Secondly, the bearing seat in the device can be movable, so it is convenient to load and separate the retainer. In addition, the device can form hot air reflux through the arc-shaped deflection surface, and can separate the retainer from the liquid through the isolation net, thereby improving the drying efficiency.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
