Description

Technical Field

[0001] The utility model relates to the technical field of coating production lines, in particular to a rotary hanger for a coating production line. Background Art

[0002] For aesthetic reasons or corrosion protection, coating is a common process used in the manufacturing of various products. Coating is a systematic process encompassing three basic steps: surface preparation before coating, coating, and drying. The coating process primarily occurs on the production line.

[0003] The spray hanger consists of a rotating sprocket and a hanging rod. The bottom of the hanging rod is a hook or thread, and each hanging point can hang a single workpiece. During spraying, the rotating sprocket drives the workpiece to rotate, allowing for rotary spraying. While suitable for rotary spraying of workpieces, this hanging method has limited freedom, making it impossible to automatically load parts and unable to adjust the height of different workpieces to be coated. Therefore, its application range is limited, and therefore has certain limitations.

[0004] For this reason, we urgently need to provide a rotary hanger for a coating production line. Utility Model Content

[0005] The purpose of the present utility model is to provide a rotary hanger for a coating production line to solve the problems raised in the above-mentioned background technology that the existing spray hanger hanging method has low degree of freedom, cannot realize automatic loading of parts, cannot be adjusted specifically according to the height of different workpieces to be coated, and has a limited scope of application.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rotary hanger for a coating production line, comprising a guide rail frame and an electric guide rail seat, wherein the electric guide rail seat is slidably connected to the inside of the guide rail frame, and a rotary device is provided below the electric guide rail seat.

[0007] The rotating device includes a rotating unit and a suspension unit.

[0008] The rotary unit includes a suspension line, a supporting beam, a rotary motor, a rotary shaft, and a rotary sprocket. The suspension line is fixedly connected to the bottom center of the electric guide rail seat, the supporting beam is fixedly connected to the bottom of the suspension line, the rotary motor is installed inside the supporting beam, the rotary shaft is connected to the output end of the rotary motor, and the rotary sprocket is fixedly connected to the bottom of the rotary shaft.

[0009] A further improvement is that the interior of the load-bearing beam is a hollow structure, and a fixed bearing is installed at the center of its bottom. The rotating shaft is rotatably connected to the inside of the fixed bearing. When the workpiece at the bottom of the suspension unit needs to be rotated, the rotating motor is started to drive the rotating shaft to rotate inside the fixed bearing, thereby driving the rotating sprocket at the bottom of the rotating shaft to rotate, thereby driving the workpiece on the suspension unit to rotate and perform comprehensive spraying on it.

[0010] A further improvement is that a heat dissipation port is provided on the left outer surface of the load-bearing beam, and a dust filter is installed inside the heat dissipation port. The setting of the heat dissipation port dissipates the heat generated when the rotary motor is running, and the setting of the dust filter prevents external dust from entering the interior of the load-bearing beam and then entering the interior of the rotary motor, causing damage to the motor.

[0011] A further improvement is that the suspension unit includes a hanger lower rod, a sliding rod, a fixing assembly, and a threaded hanger. The hanger lower rod is fixedly connected to the bottom center of the rotating sprocket, the sliding rod is slidably connected to the outside of the hanger lower rod, the fixing assembly is installed inside the bottom of the hanger lower rod, and the threaded hanger is fixedly connected to the bottom of the sliding rod. When facing workpieces of different sizes and needing to adjust the suspension height, the sliding rod is pulled to slide downward on the outside of the hanger lower rod, thereby driving the threaded hanger to slide downward, thereby achieving adjustment of the suspension height and improving the scope of application of the device.

[0012] A further improvement is that the fixing assembly includes a spring compartment, a flexible spring, and a fixing rod, the spring compartment is opened on the bottom left side of the lower rod of the hanger, the flexible spring is installed inside the spring compartment, and the fixing rod is fixedly connected to the outer end of the flexible spring and slidably connected to the inside of the spring compartment.

[0013] A further improvement is that the outer surface of the sliding rod is provided with fixing holes with the same diameter as the fixed rod at equal intervals vertically. Before pulling the sliding rod downward, the fixed rod is pressed to slide toward the inside of the spring compartment and squeeze the flexible spring until the height of the sliding rod is adjusted. The flexible spring is reset under the action of its own elasticity, and then pushes the fixing rod to protrude and snap into the inside of the fixing hole on the outer surface of the sliding rod, thereby completing the height fixation.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The coating production line uses a rotary hanger. When the workpiece at the bottom of the suspension unit needs to be rotated, the rotary motor is started to drive the rotary shaft to rotate inside the fixed bearing, thereby driving the rotary sprocket at the bottom of the rotary shaft to rotate, thereby driving the workpiece on the suspension unit to rotate and perform comprehensive spraying on it.

[0016] 2. The coating production line uses a rotary hanger. When facing workpieces of different sizes and needing to adjust the hanging height, the sliding rod is pulled downward on the outside of the hanger's lower rod, thereby driving the threaded hanger to slide downward, thereby achieving adjustment of the hanging height and improving the applicability of the device.
