[0032] In a further embodiment, an exhaust mechanism 3 is further provided at the upper end of the bracket 1, and the bottom end of the bracket 1 is fixedly connected to the base 6. An air intake mechanism 5 is provided in the base 6, and the air intake mechanism 5 is located below the conveying mechanism 2. When the workpiece is conveyed, gas is conveyed into the air intake mechanism 5 to form an airflow, which is then discharged upward by the air intake mechanism 5.

The exhaust mechanism 3 is started to increase the flow rate of the air, thereby improving the drying efficiency of the workpiece.

[0033] In this embodiment, the exhaust mechanism 3 can be formed by connecting an exhaust fan and a pipe. The exhaust fan is installed on the bracket 1, one end of the pipe is connected to the air outlet of the exhaust fan, and the other end of the pipe is connected to the air purifier, so that the airflow can be discharged from the exhaust fan and the pipe after purification.

[0034] In a further embodiment, referring to Figure 3-Figure 4 The conveying mechanism 2 includes an upper track 21, which is fixed on the bracket 1. A chain 22 is arranged below the upper track 21. The chain 22 is connected to a driving wheel 23, and the driving wheel 23 is rotatably connected to the bracket 1 through a rotating shaft, a bearing seat and a bearing.

[0035] Furthermore, at least four driving wheels 23 are provided, and the four driving wheels 23 are located at the four corners of the bracket 1 , and each driving wheel 23 is connected to a driving motor 24 , and the driving motor 24 drives the driving wheel 23 to rotate, thereby realizing the movement of the chain 22 .

[0036] Furthermore, the upper track 21 is connected to an upper roller assembly 25, which is fixedly connected to the chain 22. The upper roller assembly 25 includes a roller, an oil cup, a slide and a hanger. The roller can move along the upper track 21, which belongs to the prior art and will not be elaborated here. The lower end of the upper roller assembly 25 is fixedly connected to an upper conveying sprocket 26, and the lower end of the upper conveying sprocket 26 is fixedly connected to a hanger 27. The hanger 27 is used to install the suspension mechanism 4. The upper conveying sprocket 26 is linked to an upper conveying chain 28, and the upper conveying chain 28 is fixedly connected to a lower conveying chain 29, and the lower conveying chain 29 is linked to a lower conveying sprocket 210. The lower conveying sprocket 210 is rotatably connected to the bracket 1 through a rotating shaft, a bearing seat and a bearing.

[0037] In this embodiment, the workpiece is placed on the suspension mechanism 4, and the drive motor 24 is started to drive the driving wheel 23 to rotate, thereby driving the upper track 21 to move, and then driving the upper roller assembly 25, the upper conveying sprocket 26, the hanger 27 and the suspension mechanism 4 to move. When the upper conveying sprocket 26 contacts the upper conveying chain 28, the upper conveying sprocket 26 drives the upper conveying chain 28 to move, and then drives the lower conveying chain 29 to rotate along the lower conveying sprocket 210. Through this design, when the upper conveying sprocket 26 moves and contacts the upper conveying chain 28, the upper conveying chain 28 and the upper conveying sprocket 26 cooperate with each other to reduce the shaking of the suspension mechanism 4, so that the movement of the upper roller assembly 25 and the suspension mechanism 4 is more stable.

[0038] In a further embodiment, referring to Figure 3-Figure 4 The suspension mechanism 4 includes a material rack body 41, an upper shell 42 is arranged at the lower end of the material rack body 41, a first fixing sleeve 43 is fixedly connected to the upper end of the upper shell 42, the first fixing sleeve 43 is fixedly connected to the material rack body 41 by bolts, the upper shell 42 is provided with a groove structure opening downward, an upper magnet 44 is installed in the groove structure, a second fixing sleeve 45 is fixedly connected to the upper end of the material rack body 41, and the second fixing sleeve 45 is fixedly connected to the upper roller assembly 25 by a pin or bolts.

[0039] In this embodiment, the material rack body 41 is convenient for installation and disassembly with the upper roller assembly 25, and the upper shell 42 and upper magnet 44 arranged at the bottom of the material rack body 41 can play the role of counterweight, increase the weight of the lower end of the material rack body 41, and thereby improve the stability of the material rack body 41.

[0040] In a further embodiment, referring to Figure 6-Figure 8 The air intake mechanism 5 includes an air intake pipe 51, which is arranged in the base 6, and the base 6 has a second groove 62 corresponding to the air intake pipe 51. The air intake pipe 51 is located in the second groove 62, so that the upper end surface of the air intake pipe 51 is lower than the upper end surface of the base 6, so as to avoid deformation caused by squeezing the air intake pipe 51 when workers walk or transport.

[0041] In one embodiment, one end of the air inlet pipe 51 is connected to a fan through a pipeline, and the fan is started to transport gas into the air inlet pipe 51 .

[0042] In another embodiment, the air inlet pipe 51 may also be connected to an electric heater and a fan, and the electric heater and the fan are started to transport the gas heated by the electric heater to the air inlet pipe 51, thereby further improving the drying efficiency of the workpiece.

[0043] In this embodiment, the air intake mechanism 5 also includes an end cover 52, and the side wall of the end cover 52 is provided with a plurality of fixing feet 53, and the fixing feet 53 are provided with fixing holes to facilitate the installation of the end cover 52. A plurality of through holes 54 are arranged on the end cover 52, and the axis of the through hole 54 is arranged along the vertical direction. The diameter of the through hole 54 can be set according to actual conditions.

[0044] In this embodiment, a first groove 61 is opened on the base 6, and the end cover 52 is located at the upper end of the first groove 61. The width of the end cover 52 is greater than the width of the first groove 61, so that the end cover 52 can block the upper end opening of the first groove 61 after installation, so that a chamber for air flow is formed in the first groove 61. The air passes through the chamber and then flows upward from the through hole 54 to form an airflow, which dries the workpiece passing above the through hole 54, so that the paint sprayed on the surface of the workpiece dries quickly, thereby improving production efficiency, and the airflow is discharged along the exhaust mechanism 3, which can reduce the paint smell in the air and reduce pollutants in the air.

[0045] In this embodiment, a lower track 55 is further provided in the first groove 61 . The structural design of the lower track 55 is the same as that of the upper track 21 . The sizes of the lower track 55 and the upper track 21 are also the same. A support seat 57 is provided at the lower end of the lower track 55 , and the support seat 57 supports the lower track 55 .

[0046] In another embodiment, the support seat 57 can also be configured as a height-adjustable screw and internal threaded sleeve, thereby facilitating the adjustment of the height of the lower track 55 so that the lower track 55 remains stable and avoids large drop differences at different positions.

[0047] Furthermore, a lower positioning piece 56 is installed on the lower track 55, and the lower positioning piece 56 can move along the lower track 55. The lower positioning piece 56 is magnetic, and there is a gap between the upper end surface of the lower positioning piece 56 and the upper magnet 44, so that the upper magnet 44 and the lower positioning piece 56 attract each other under the action of magnetic force. When the upper magnet 44 moves with the material rack body 41, the lower positioning piece 56 is driven to move along the lower track 55 under the action of magnetic force. Since the structural design and size of the lower track 55 and the upper track 21 are the same, the lower positioning piece 56 and the upper magnet 44 move synchronously, and the upper magnet 44 is limited by the lower positioning piece 56, thereby reducing the shaking of the bottom of the suspension mechanism 4, further improving the stability of the movement of the suspension mechanism 4, and then reducing the wear of the upper roller assembly 25 and the upper conveying sprocket 26, the upper conveying chain 28 and the lower conveying chain 29 due to shaking during transportation, thereby extending the service life of the equipment.

[0048] In this embodiment, the lower positioning member 56 includes a lower shell 561, and the lower shell 561 is provided with a groove structure opening upward, and a lower magnet 562 is installed in the groove structure. The lower end of the lower shell 561 is fixedly connected to the lower roller assembly 563, and the lower roller assembly 563 is movably connected to the lower track 55. The lower magnet 562 and the upper magnet 44 attract each other under the action of magnetic force. When the upper magnet 44 moves with the material rack body 41, under the action of magnetic force, it drives the lower shell 561, the lower magnet 562 and the lower roller assembly 563 to move along the lower track 55.

[0049] The working principle of the present invention is as follows: place the workpiece on the suspension mechanism 4, start the drive motor 24 to drive the driving wheel 23 to rotate, drive the upper track 21 to move, and then drive the upper roller assembly 25, the upper conveying sprocket 26, the hanger 27 and the suspension mechanism 4 to move. When the upper conveying sprocket 26 contacts the upper conveying chain 28, the upper conveying sprocket 26 drives the upper conveying chain 28 to move, and then drives the lower conveying chain 29 to rotate along the lower conveying sprocket 210. Through this design, when the upper conveying sprocket 26 moves and contacts the upper conveying chain 28, the upper conveying chain 28 and the upper conveying sprocket 26 cooperate with each other to reduce the shaking of the suspension mechanism 4, so that the movement of the upper roller assembly 25 and the suspension mechanism 4 is more stable, and the external air enters the first groove 61 from the air inlet pipe 51, and then flows upward from the through hole 54 through the chamber to form an airflow. The workpiece above the through hole 54 is dried so that the paint sprayed on the surface of the workpiece dries quickly, thereby improving production efficiency, and the airflow is discharged along the exhaust mechanism 3, which can reduce the smell of paint in the air and reduce pollutants in the air. When the upper magnet 44 moves with the material rack body 41, the lower positioning member 56 is driven to move along the lower track 55 under the action of magnetic force. Since the structural design and size of the lower track 55 and the upper track 21 are the same, the lower positioning member 56 and the upper magnet 44 move synchronously, and the upper magnet 44 is limited by the lower positioning member 56, thereby reducing the shaking of the bottom of the suspension mechanism 4, further improving the stability of the movement of the suspension mechanism 4, and then reducing the wear of the upper roller assembly 25 and the upper conveying sprocket 26, the upper conveying chain 28 and the lower conveying chain 29 due to shaking during transportation, thereby extending the service life of the equipment.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
