Description

Technical Field

[0001] This utility model relates to the field of bolt processing equipment technology, and more specifically, to a drying device for high-strength bolts after surface treatment. Background Technology

[0002] High-strength bolts are bolts made of high-strength steel or bolts that require a large preload. After surface treatment, the bolts contain moisture and need to be dried.

[0003] In the prior art, when drying bolts, a conveyor belt can be used to move the bolts. During the movement, a fan blows air onto the bolts, which facilitates drying. However, a large number of bolts accumulate on the conveyor belt. Bolts on the surface can be dried quickly, but bolts at the bottom, where they are in contact with the conveyor belt and the air contact area are smaller, resulting in lower drying efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of low bolt drying efficiency by designing a high-strength bolt surface treatment drying device.

[0005] To achieve the above objectives, the technical solution of this utility model is a high-strength bolt surface treatment drying device, including a conveyor belt device that can drive the surface-treated bolts to move. A drying box is installed at the upper end of the conveyor belt device, and a hot air fan is installed at the upper end of the drying box. An air guide pipe is installed at the outlet end of the hot air fan, and the air guide pipe can guide hot air into the drying box. A flipping frame is installed inside the drying box, and the flipping frame can flip the bolts.

[0006] Furthermore, the tilting frame includes rotating shafts located on both sides inside the drying chamber. Rolling bearings are installed at both ends of the rotating shafts. The rolling bearings are installed inside the drying chamber. A servo motor is installed on one side of the drying chamber. A circular hole is opened on the drying chamber. The rotating end of the servo motor passes through the circular hole and is connected to a rotating shaft. A ring-shaped permanent magnet is installed on the outside of the rotating shaft. A ring-shaped conveyor belt is provided inside the drying chamber. The ring-shaped conveyor belt is supported by two ring-shaped permanent magnets.

[0007] Furthermore, the two rotating shafts are inclinedly distributed inside the drying chamber, with the rotating shaft closer to the starting end of the conveyor belt device positioned lower and the rotating shaft further away from the starting end of the conveyor belt device positioned higher, and a baffle is installed on the outer side of the annular conveyor belt.

[0008] Furthermore, an inclined material guide channel is installed at the lower end of the drying chamber, which can guide bolts that fall off the annular conveyor belt to the side of the conveyor belt device near the lower rotating shaft.

[0009] Furthermore, the drying chamber is equipped with a multi-port pipe, the inlet end of which is connected to the outlet end of the air duct, and the multiple outlet ends of the multi-port pipe can point to different positions on the conveyor belt device and the tilting frame, respectively.

[0010] The beneficial effects of this utility model are as follows: the bolts on the conveyor belt device can be flipped by the flipping frame, and hot air can be blown into the drying box by the hot air blower to dry the bolts. The air guide pipe can first blow hot air above the bolts on the conveyor belt device to initially dry one side of the bolts. After drying, the bolts can be flipped by the flipping frame to dry the other side of the bolts, thereby improving the drying efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0014] This utility model provides, for example Figure 1-3 The high-strength bolt surface treatment drying device shown includes a conveyor belt device 1, which can drive the surface-treated bolts to move. A drying box 2 is installed at the upper end of the conveyor belt device 1, and a hot air blower 3 is installed at the upper end of the drying box 2. An air guide pipe 4 is installed at the outlet end of the hot air blower 3, which can introduce hot air into the drying box 2. A turning frame 5 is installed inside the drying box 2, which can turn the bolts.

[0015] The bolt drying process of this device is as follows: The bolt is placed on the conveyor belt device 1. The operation of the conveyor belt device 1 can move the bolt into the drying chamber 2. The hot air fan 3 is started. The hot air fan 3 can heat the air and discharge it into the drying chamber 2 through the air guide pipe 4 to dry the bolt on the conveyor belt device 1. When the bolt moves to the flipping frame 5, the bolt can be flipped by the flipping frame 5. After the bolt is flipped, the other side of the bolt can also be dried through the air guide pipe 4. After the bolt is dried, the bolt can be unloaded by the conveyor belt device 1.

[0016] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The rotating frame 5 includes a rotating shaft 6 located on both sides inside the drying chamber 2. Rolling bearings 7 are installed at both ends of the rotating shaft 6. The rolling bearings 7 are installed inside the drying chamber 2. A servo motor 8 is installed on one side of the drying chamber 2. A circular hole 9 is opened on the drying chamber 2. The rotating end of the servo motor 8 passes through the circular hole 9 and is connected to a rotating shaft 6. A circular permanent magnet 10 is installed on the outside of the rotating shaft 6. A circular conveyor belt 11 is provided inside the drying chamber 2. The circular conveyor belt 11 is supported by two circular permanent magnets 10.

[0017] The process of the flipping frame 5 flipping the bolt is as follows: When the bolt moves to the rotating shaft 6 on the starting end side, it can be attracted to the annular conveyor belt 11 by the annular permanent magnet 10, causing the bolt to flip. The servo motor 8 is started to rotate. The servo motor 8 can drive the rotating shaft 6 and the annular permanent magnet 10 on the rotating shaft 6 to rotate. The two annular permanent magnets 10 are connected by the annular conveyor belt 11, which can then rotate and drive the annular conveyor belt 11 to rotate. When the annular conveyor belt 11 rotates, the bolt can be moved. Then the bolt can be dried by the air duct 4. When the bolt rotates to the lower position on the annular conveyor belt 11, the bolt can fall off.

[0018] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2Two rotating shafts 6 are inclinedly distributed inside the drying chamber 2. The rotating shaft 6 on the side closer to the starting end of the conveyor belt device 1 is lower, and the rotating shaft 6 on the side farther away from the starting end of the conveyor belt device 1 is higher. A baffle 12 is installed on the outside of the annular conveyor belt 11 to tilt the two rotating shafts 6. This allows the bolt to move upward when the annular conveyor belt 11 moves, which can prolong the time the bolt stays in the drying chamber 2. The baffle 12 can prevent the bolt from slipping downward.

[0019] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 An inclined guide channel 13 is installed at the lower end of the drying chamber 2. The inclined guide channel 13 can guide the bolts that fall off the annular conveyor belt 11 to the side of the rotating shaft 6 near the lower position on the conveyor belt device 1. After the bolts fall off the annular conveyor belt 11, they can fall onto the inclined guide channel 13. Under the action of the inclined surface of the inclined guide channel 13, the bolts can slide towards the front of the conveyor belt device 1, thereby prolonging the time that the bolts stay in the drying chamber 1.

[0020] Refer to the instruction manual appendix Figure 1 The drying chamber 2 is equipped with a multi-port pipe 14. The inlet end of the multi-port pipe 14 is connected to the outlet end of the air guide pipe 4. The multiple outlet ends of the multi-port pipe 14 can point to different positions on the conveyor belt device 1 and the tilting frame 5, which can facilitate precise drying of bolts and improve drying efficiency.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
