Description

Technical Field

[0001] The invention relates to the technical field of wooden comb processing, and in particular to an automatic painting device and a painting method for wooden combs. Background Art

[0002] Combs are an indispensable tool in people's lives, but as people become more aware of health, more and more people are beginning to pay attention to wooden combs made of natural materials. The biggest advantage of wooden combs is that they are free of static electricity, can effectively stimulate acupuncture points, promote blood circulation in the head cortex, unclog meridians, clear the brain and refresh the mind, adjust blood and qi, and have obvious effects on enhancing memory, insomnia, dizziness, and hair loss, achieving a perfect unity of practicality and health care.

[0003] The types of wooden combs are roughly divided into: green sandalwood, black ebony, peach wood, red wood, jujube wood, etc. The production process can be divided into whole wood and pieced wood. But no matter what material or process is used for production, since the natural texture of the wooden comb cannot guarantee that the wooden comb itself has enough beauty, the surface of the wooden comb needs to be sprayed with paint.

[0004] However, currently, most of the painting devices for wooden combs place the wooden comb flat on a painting table, and spray paint back and forth manually or automatically. After spraying one side, wait for it to solidify before spraying the other side. This is inefficient, and this painting method will also spray paint on the comb teeth. The paint on the comb teeth will come into direct contact with the hair and scalp, and the paint will remain in the hair due to friction. Its harmful substances will enter the body and affect health. Summary of the invention

[0017] S1. The comb back of the wooden comb is inserted into the socket and transported to the bottom of the circular side plate at intervals through the feeding belt. The telescopic arm is rotated to the bottom through the rotating arm. At this time, the first conductive head contacts the second arc-shaped conductive rail, and the second conductive head contacts the power receiving seat below. The controller first energizes the power receiving seat below, and the second spring is energized and contracted to drive a pair of clamps to separate, and then the pair of clamps are rotated to the two sides of the corresponding wooden comb. The second spring is de-energized, and the pair of clamps clamp the comb teeth of the wooden comb under the action of the second spring. The controller then energizes the second arc-shaped conductive rail, and then energizes the first spring through the first conductive head, and then the telescopic arm is contracted to pull the wooden comb out of the socket to realize the feeding process;

[0020] S4. When the bevel gear rotates through the arc-shaped tooth plate, it drives the telescopic arm to rotate 90°. At this time, the second conductive head contacts the power socket on the lower left, and a pair of second springs are energized and contracted, driving a pair of clamps to separate, thus releasing the wooden comb and dropping it onto the unloading belt for delivery.

[0021] The beneficial effects of the present invention are:

[0022] 1.

[0023] 2. By installing the cleaning chamber, the rotating arm drives the clamped wooden comb to rotate counterclockwise. When it reaches the front of the cleaning chamber, the first conductive head first contacts the first arc-shaped conductive rail, the telescopic arm contracts and detaches from the first arc-shaped conductive rail, and the telescopic arm is reset, so that the clamped wooden comb can bypass the chamber wall and enter the cleaning chamber. The comb back of the wooden comb passes through a pair of rotating cleaning rollers, and the second motor is started. The gear set drives a pair of dust suction shafts to rotate, and then drives a pair of cleaning rollers to rotate, so as to clean up the impurities on the surface of the comb back. At the same time, the dust suction shaft is continuously sucked through the dust suction pipe, and the swept impurities are absorbed through multiple dust suction holes to improve the subsequent painting effect.

[0024] 3. By installing a primary spray paint room, a primary drying room, a secondary spray paint room and a secondary drying room, first spray a layer of primer on the back of the comb through a pair of arc-shaped spray paint tubes in the primary spray paint room, and then enter the secondary spray paint room to spray a layer of surface paint after drying, and finally enter the secondary drying room for drying and transfer out, completing the painting process on both sides simultaneously, and a pair of plywood clamps and covers the comb teeth at the same time to prevent the comb teeth from being sprayed with paint, thereby preventing the paint from contacting the hair.

[0025] 4. By installing the unloading belt, arc-shaped tooth plate and bevel gear, when the bevel gear rotates through the arc-shaped tooth plate, it drives the telescopic arm to rotate 90°.
