Description

Technical Field

[0001] The utility model relates to the technical field of pulley processing equipment, in particular to a pulley surface spraying device. Background Art

[0002] Belt pulleys are hub-type parts that are generally relatively large in size and are manufactured using casting and forging as the primary methods. During the production process, they require a paint treatment to enhance their appearance while preventing rust.

[0003] The existing technology has the following deficiencies: The prior art publication number CN220803894U states, "A device for spraying paint on the surface of a pulley" that "includes a paint spray device, which includes a paint spray tank, a motor, a mounting bracket, a first rotating shaft, a second rotating shaft, a hand crank, a fixing plate, a paint spray box, a spray head, a circuit controller, a mounting box, a support shaft, and a push plate. The motor is fixedly mounted at the middle end of the side of the paint spray tank, the paint spray box is fixedly mounted at the middle end of the bottom of the top surface of the paint spray tank, the spray head is fixedly mounted at the middle end of the top of the paint spray box, the circuit controller is located on the side of the paint spray tank near the hand crank, the mounting box is fixedly mounted at the middle end of the front of the paint spray tank, and the push plate is fixedly mounted at one end of the support shaft."

[0004] The above structure fixes the pulley to the side of the fixed plate through the chuck installed by the thread on the side of the fixed plate. The starting motor drives the rotating shaft to stably drive the fixed plate to rotate. However, this structure does not make any improvements to the painting of the groove in the middle of the pulley. Since there are varying numbers of annular inner grooves in the middle of most pulley structures, there are many blind angles in the spraying of the pulley, and traditional direct spraying is difficult to completely cover the position of the inner groove. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a pulley surface spraying device, which solves the problem that the traditional spraying is difficult to cover the groove position inside the pulley.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pulley surface painting device, comprising a device body, a control panel, and a motor, wherein the control panel is arranged on the oblique upper end surface of the device body, and the motor is arranged on the inner end surface of one side of the device body;

[0007] A center shaft connection mechanism is provided in the middle of the device body, and a pulley is provided on the periphery of the center shaft connection mechanism;

[0008] The median axis connection mechanism further includes a triangular axis seat and a bearing bracket. The triangular axis seat is plugged into the end of the median axis connection mechanism, and the bearing bracket is movably connected to the other end of the median axis connection mechanism.

[0009] As an optimal technical solution of the present invention, the triangular shaft seat is specifically composed of a columnar shaft seat in the middle and strip-shaped connecting structures on both sides, wherein the strip-shaped connecting structures on both sides extend obliquely upward until they are inserted into the interior of the equipment body, and the columnar shaft seat structure in the middle contains a bearing.

[0010] As an optimal technical solution of the present invention, the equipment body also includes a guide wheel and a paint spray port. The guide wheel is movably connected to the inner end of the equipment body, and the paint spray port is fixedly installed inside the equipment body near the top and extends outward.

[0011] As a preferred technical solution of the present invention, the portion of the paint spray port that extends beyond the outside of the equipment body is in a right-angle structure, with its end aligned with the groove position in the middle of the pulley.

[0012] As an optimal technical solution of the present invention, the guide wheel is embedded in the equipment body, and only the outer end part exceeds the inner wall end face of the equipment body, and is distributed in the left, right and bottom directions of the pulley, and four groups are arranged according to the distribution of the pulley position.

[0013] As a preferred technical solution of the present invention, the guide wheels on the left and right sides of the pulley are connected to the external motor through a transmission mechanism, and the guide wheel located below the pulley does not have a drive connection.

[0014] As a preferred technical solution of the present invention, one end of the paint spray port extending inside the equipment body is connected to a paint supply pipe inside the equipment body. This structure requires the preparation of paint raw materials and a pump in advance.

[0015] Compared with the prior art, the present invention provides a pulley surface painting device, which has the following beneficial effects:

[0016] The device for spraying paint on the surface of a pulley is provided with a center shaft connection mechanism, a guide wheel, a bearing bracket and a triangular shaft seat. When the device is spraying paint on the pulley, the operator needs to first prepare the spraying material to establish a supply line for the paint spraying port, and then the operator removes the triangular shaft seat from the side end of the device body, so that one end of the center shaft connection mechanism is exposed to the outside, and the pulleys to be painted are sequentially sleeved on the periphery of the center shaft connection mechanism, and finally the triangular shaft seat is installed back to its original position. At this time, the operator controls the paint spraying port and the motor through the control panel, and the motor drives the guide wheels on the left and right sides to rotate. The pulley is driven to rotate as a whole by the drive of the wheel. At this time, the paint nozzle is aimed at the groove position in the middle of the pulley for paint spraying. The paint spraying range is continuously expanded during continuous rotation until the middle groove position is completely covered with paint after the pulley rotates one circle. Through the above process and settings, the equipment can not only automatically paint multiple groups of pulleys at the same time, but also completely spray the concave part in the middle of the pulley through a special placement method and paint nozzle position. Compared with traditional side spraying, this spraying method effectively makes up for the defect that the groove structure in the pulley is difficult to spray cover.
