Description

Technical Field

[0001] This utility model belongs to the technical field of coating line circulating drying equipment, and more specifically, it relates to a coating line circulating drying equipment. Background Technology

[0002] A coating line circulating drying equipment refers to equipment used on a coating production line to dry and cure workpieces after spraying. Its main function is to transfer heat to the workpiece through hot air circulation, causing the powder or paint on the workpiece surface to melt, level, and adhere into a film, ultimately forming a high-quality coating with both protective and decorative properties. Chinese Patent No. CN202320115462.2 discloses a graded multi-heat source circulating drying equipment for an automotive coating production line, including a drying chamber. Multiple spaced guide pipes are connected to the back side of the drying chamber, and a circulating air duct is connected to the back side of these guide pipes. Vertical rods are rotatably mounted at both ends of the top of the drying chamber, with sprockets fixedly fitted at the lower ends of the vertical rods. A chain drives between the two sprockets. A motor is fixedly mounted on the top of the drying chamber, and the output end of the motor passes through the drying chamber and is fixedly connected to the vertical rods. Multiple support plates are fixedly mounted on the outer wall of the chain, and rotating rods are rotatably mounted inside the support plates. A clamping mechanism is located at the bottom of the rotating rods. This invention enables comprehensive heating and drying of all parts of automotive components after coating.

[0003] Based on the above, the inventors have discovered the following problems:

[0004] The aforementioned circulating drying equipment for the coating line cannot save energy and cannot adjust the direction of the circulating hot air, resulting in uneven drying of different parts of the metal components.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a circulating drying equipment for coating lines in order to achieve a more practical purpose. Utility Model Content

[0006] The purpose and effect of this utility model's circulating drying equipment for coating lines are achieved through the following specific technical means:

[0007] A coating line circulating drying equipment includes a drying chamber, a conveyor chain, vent pipes, an electric fan, an electric heating rod, and an adjustment component. The drying chamber has doors on both sides, and the conveyor chain passes through the doors and is located above the drying chamber. Several vent pipes are provided on the drying chamber, and the two ends of the vent pipes are respectively connected to the side walls of the drying chamber. Several operating chambers are provided on both sides of the drying chamber. An electric fan is provided in each operating chamber. An electric heating rod is provided on the side of the electric fan facing the drying chamber and located in the operating chamber. An adjustment component is provided on the side of the electric heating rod located in the operating chamber, and the vent pipes are connected to the operating chambers.

[0008] Furthermore, the adjustment assembly includes a motor, a rotating rod, a pair of moving rods, a connecting cavity, a connecting shaft, a connecting shaft, a guide plate, and a pair of fixed rods. The two ends of the pair of fixed rods are fixedly disposed on both sides of the running cavity, and several connecting shafts are movably disposed on the fixed rods. The connecting shafts are connected to the centers of both sides of the guide plate. A connecting shaft is disposed on one side of the connecting shaft and on the guide plate. The end of the connecting shaft away from the guide plate is movably disposed on the moving rod. The top end of the moving rod is movably disposed at the top of the running cavity. A connecting cavity is disposed at the lower end of the moving rod. The connecting cavity passes through the bottom end of the running cavity and is threadedly connected to the rotating rod. A motor is disposed at the end of the rotating rod away from the connecting cavity.

[0009] Furthermore, both the movable rod and the fixed rod are arranged parallel to each other in the vertical direction.

[0010] Furthermore, all the adjustment components are made of heat-resistant materials.

[0011] Furthermore, the vent pipe is made of heat-resistant material.

[0012] Furthermore, the outer wall of the drying chamber is provided with a heat insulation layer.

[0013] Furthermore, the drying chamber has a heat insulation layer on its side wall.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, when it is necessary to dry coated metal, the metal is fixed on a conveyor chain, which then moves the metal into the drying chamber. At this time, an electric fan and heating rod are activated to circulate hot air in the running chamber, drying chamber, and ventilation pipe, thereby reducing heat loss and saving energy. Simultaneously, the motor is activated to drive the rotating rod to rotate, which in turn moves the connecting chamber up and down along the rotating rod, moves the moving rod up and down relative to the fixed rod, and causes the guide plate to rotate around the axis of the connecting shaft. This changes the position of the hot air blowing onto the metal surface, thus achieving uniform drying of various parts of the metal component.

[0016] The design of the insulation layer on the side wall of the drying chamber can keep the heat inside the drying chamber warm, reduce heat loss inside the drying chamber, and save energy. Attached Figure Description

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a coating line circulating drying equipment, including a drying chamber 1, a conveyor chain 2, an air pipe 3, an electric fan 4, an electric heating rod 7, and an adjustment component. The drying chamber 1 has doors on both sides, and the conveyor chain 2 passes through the doors and is located above the drying chamber 1. The drying chamber 1 is provided with several air pipes 3, and the two ends of the air pipes 3 are respectively connected to the side walls of the drying chamber 1. Several operating chambers 6 are provided on both sides of the drying chamber 1. An electric fan 4 is provided in each operating chamber 6.

[0029] The aforementioned conveyor chain 2 is prior art as cited in the patent.

[0030] The adjustment assembly includes a motor 10, a rotating rod 15, a pair of moving rods 9, a connecting cavity 14, a connecting shaft 12, a connecting shaft 11, a guide plate 5, and a pair of fixed rods 8. The two ends of the pair of fixed rods 8 are fixedly disposed on both sides of the running cavity 6, and several connecting shafts 11 are movably disposed on the fixed rods 8. The connecting shafts 11 are connected to the centers of both sides of the guide plate 5. A connecting shaft 12 is disposed on one side of the connecting shaft 11 and on the guide plate 5.

The connecting cavity 14 passes through the bottom end of the running cavity 6 and is threadedly connected to the rotating rod 15. A motor 10 is disposed at the end of the rotating rod 15 away from the connecting cavity 14.

[0031] When it is necessary to dry the coated metal, the metal is fixed on the conveyor chain 2, which then moves the metal into the drying chamber 1. At this time, the electric fan 4 and the heating rod 7 are started, so that the hot airflow circulates in the running chamber 6, the drying chamber 1 and the ventilation pipe 3, thereby reducing heat loss and saving energy.

[0033] All of the adjustment components are made of heat-resistant materials.

[0034] The vent pipe 3 is made of heat-resistant material;

[0035] By using heat-resistant materials for the vent pipe 3 and the regulating component, the regulating component and the vent pipe 3 can operate normally under high temperature conditions.

[0036] The drying chamber 1 has a heat insulation layer on its outer wall;

[0037] By incorporating a heat insulation layer on the outer wall of the drying chamber 1, heat inside the drying chamber 1 can be prevented from being transferred to the outer wall, thus reducing the risk of burns to operators.

[0038] The drying chamber 1 has a heat insulation layer on its side wall;

[0039] By incorporating an insulation layer on the side wall of the drying chamber 1, the heat inside the drying chamber 1 can be kept warm, reducing heat loss and saving energy.

[0040] The specific usage and function of this embodiment are as follows:

[0041] In this invention, when it is necessary to dry the coated metal, the metal is fixed on the conveyor chain 2, and the conveyor chain 2 moves the metal into the drying chamber 1. At this time, the electric fan 4 and the electric heating rod 7 are started, so that the hot airflow circulates in the running chamber 6, the drying chamber 1 and the ventilation pipe 3, thereby reducing heat loss and saving energy. At the same time, the motor 10 is started to drive the rotating rod 15 to rotate, which drives the connecting chamber 14 to move up and down along the rotating rod 15, drives the moving rod 9 to move up and down relative to the fixed rod 8, and drives the guide plate 5 to rotate around the axis of the connecting shaft 11. This can change the position of the hot air blowing on the metal surface, thereby achieving uniform drying of various parts on the metal parts.
