Description

Technical Field

[0001] This utility model pertains to coating curing, specifically a fastener coating curing device. Background Technology

[0002] Fasteners, also known as standard parts in the market, are a general term for a class of mechanical parts used to fasten two or more parts (or components) together into a whole. Fastening bolts are a type of fastener, specifically cylindrical threaded fasteners that are fitted with nuts. They have the characteristics of connection, fixation, and disassembly. After processing, fasteners are usually coated with a coating to protect the workpiece. To speed up the production rate of fasteners, a curing device is needed to accelerate the curing of the coating after it is applied.

[0003] Existing coating curing devices often result in fasteners being removed directly after curing due to their high surface temperature, which can easily burn workers. The fasteners must be allowed to cool down before removal, and the drying oven remains idle during this time, preventing continuous drying operations and significantly impacting the production and processing speed of the fasteners.

[0004] To address the aforementioned problems, this application proposes a fastener coating curing device. Utility Model Content

[0005] The purpose of this invention is to provide a fastener coating curing device that solves the problems mentioned in the background art.

[0013] This utility model has the following beneficial effects:

[0014] This invention uses a motor to rotate the position of the lids, alternately drying and curing the fastener coatings placed on the trays under the two lids, reducing the idle time of the curing chamber and improving the curing efficiency of the fastener coatings per unit time.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements 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.

[0027] Please see Figure 1-5 As shown, this utility model is a fastener coating curing device, including a base 1 and a gantry frame 2, two box covers 7 symmetrically arranged on the left and right sides of the gantry frame 2, rotating columns 10 arranged in a circular array below, and placement trays 11 evenly distributed longitudinally on the outer wall of the rotating columns 10. A curing box 6 that cooperates with the box covers 7 is provided on the right side of the top surface of the base 1. A motor 3 is provided above the gantry frame 2, which can exchange the positions of the box covers 7. Gears 9 are provided below the box covers 7, the same number as the rotating columns 10, and are fixed coaxially with the rotating columns 10. All gears 9 mesh with gears 8 below the gantry frame 2. A motor 5 is provided above the box covers 7 to drive gears 8 to rotate, and the placement trays 11 are rotated by the motor 5.

[0028] This embodiment provides a fastener coating curing device. The two lids 7 are switched by a motor 3, so that the fasteners placed on the tray 11 under the lid 7 are alternately put into the curing chamber 6 for drying and curing. This reduces the idle time of the curing chamber 6 and improves the operating efficiency of the device. Multiple fasteners can be placed on the tray 11. The tray 11 is rotated by a motor 5 to ensure that the fasteners placed on the tray 11 are heated evenly, thereby improving the efficiency and quality of fastener coating curing.

[0029] The base 1 has a fan 12 on its top surface, and the air outlet of the fan 12 is connected to the heating box 13. The middle part of the bottom plate of the curing box 6 is equipped with a vertical air supply duct 14. The outer wall of the air supply duct 14 has evenly distributed air outlets. The heating box 13 and the air supply duct 14 are connected by a hot air pipe 1301. The fan 12 sends air into the heating box 13 for heating. The heated air is then sent into the curing box 6 through the hot air pipe 1301 and the air supply duct 14 to dry and cure the fastener coating.

[0030] The base 1 has an air outlet 15 on the left side of its top surface. The air outlet of the fan 12 is also connected to the air outlet 15. After the box cover 7 is switched, the placement tray 11 containing the newly cured fasteners is located above the air outlet 15. The fan 12 sends air to the air outlet 15 to cool the fasteners and prevent workers from being burned when they take the fasteners away.

[0031] The gantry 2 has a connecting plate 301 below the top plate, and the connecting plate 301 is connected to the drive shaft of the motor 3. The connecting plate 301 has hydraulic push rods 4 on both the left and right sides below it, and the output end of the hydraulic push rods 4 is connected to the connecting frame 701 above the cover 7. The hydraulic push rods 4 drive the cover 7 to move up and down, and drive the fasteners to leave and enter the curing box 6, so as to prevent the rotating column 10, the placement plate 11 or the fasteners from colliding with the curing box 6 during the rotation of the cover 7 by the motor 3.

[0032] The placement disk 11 has circumferentially distributed placement grooves 1101. The screw portion of the fastener passes through the bottom of the placement groove 1101. The fastener is placed through the placement groove 1101 to prevent the fastener from being thrown out during the rotation of the placement disk 11.

[0033] The outer wall of the curing chamber 6 is equipped with a laser emitter 16 via a mounting bracket, and the outer wall of the chamber cover 7 is equipped with a laser receiver 17 that cooperates with the laser emitter 16 via a mounting bracket. The cooperation of the laser emitter 16 and the laser receiver 17 enables the positioning of the chamber cover 7 and the curing chamber 6, ensuring that the curing chamber 6 and the chamber cover 7 can be accurately closed, and preventing the rotating column 10, the placement tray 11 or the fasteners from colliding with the air supply tube 14.

[0034] It is understandable that this invention can reduce the idle time of the curing chamber 6, increase the number of fasteners whose coating is dried and cured per unit time, and secondly, enable the fasteners to be heated evenly, thereby improving the efficiency and quality of fastener coating curing.

[0035] A specific application of the operation process in this embodiment is as follows: The fastener is placed in the placement slot 1101 below a box cover 7. Then, the hydraulic push rod 4 is driven to move the rotating column 10 upwards. Then, the drive motor 3 rotates the box cover 7 above the curing chamber 6. Precise positioning is achieved through the cooperation of the laser emitter 16 and the laser receiver 17. Then, the hydraulic push rod 4 is driven to move the box cover 7 downwards to close with the curing chamber 6. The fan 12 sends air to the heating chamber 13 for heating. The heated air is then blown into the curing chamber 6 through the air supply duct 14 to dry and cure the fastener coating. The drive motor 5 rotates the rotating column 10 to improve the uniformity of heating of the fastener and enhance its performance. The curing rate and quality of the coating are determined by the drying process of the fasteners under the cover 7. During this process, the operator places new fasteners into the placement slot 1101 under another cover 7. After the fasteners in the curing chamber 6 are dried, the hydraulic push rod 4 is driven to move the cover 7 upwards, causing the dried fasteners to leave the curing chamber 6. The drive motor 3 drives the two covers 7 to exchange positions, and the hydraulic push rod 4 drives the cover 7 downwards. At this time, the newly placed fasteners enter the curing chamber 6 for drying. The dried fasteners are located above the air outlet 15, and the fan 12 blows air to accelerate the cooling of the fasteners, making it easier to remove the fasteners and put in new fasteners.
