[0040] The driving rod 82 moves along its own length direction, and causes the slider 84 to reciprocate along the width direction of the fixing plate 83 through the transmission component 91 .

[0041] The conducting component 91 includes a connecting plate 92, a sliding rod 93, and a first W-shaped groove 94. The first W-shaped groove 94 is formed by combining a plurality of first V-shaped grooves and is opened on the fixed plate 83; the first W-shaped groove 94 is arranged along the length direction of the fixed plate 83. The sliding rod 84 and the connecting plate 92 are respectively located on the upper surface and the lower surface of the fixed plate 83, one end of the sliding rod 93 is fixed on the sliding rod 84, and the other end of the sliding rod 93 is fixed on the connecting plate 92 after passing through the first W-shaped groove 94, the lower surface of the sliding rod 84 is in contact with the upper surface of the fixed plate 83, and the upper surface of the connecting plate 92 is in contact with the lower surface of the fixed plate 83.

The length of the transverse groove 821 is greater than the amplitude of the first W-shaped groove 94.

[0042] The product is removed from the placement table 12, and the power cylinder 81 is turned on. The driving rod 82 moves along its own length direction, the slider 84 moves along the length direction of the fixed plate 83, and the slide bar 93 moves along the inner wall of the first W-shaped groove 94, so that the slider 84 moves parallel to the first W-shaped groove 94, so that the clapper 86 can reciprocate and hit the side wall of the printing head 53.

[0043] Vertical plates 95 are vertically fixedly connected to both sides of the fixed plate 83, and contact plates 96 are slidably connected to the vertical plates 95.

The adsorbent 107 is a transparent tape, and the adhesive surface of the transparent tape faces upward to pick up dust on the lower surface of the printing head 53.

[0047] After the printing head 53 prints fifty products, the printing head 53 is slightly lifted up after the printing is completed, and the products are moved away from the bottom of the printing head 53. The power cylinder 81 is turned on, the driving rod 82 moves along its own length direction, and the slider 84 moves along the length direction of the first W-shaped groove 94, so that the clapper 86 on the slider 84 hits the side wall of the printing head 53 to knock off the dust on the printing head 53. As the driving rod 82 moves further, the connecting rod 105 drives the contact plate 96 to move along the length direction of the second W-shaped groove 104. After the clapper 86 is separated from the printing head 53, the adsorbent 107 on the contact plate 96 contacts the lower surface of the printing head 53, and the dust on the lower surface of the printing head 53 is removed by the action of viscosity, thereby achieving the self-cleaning effect of the printing head 53. Finally, the driving rod 82 is reset by the power cylinder 81, so that the clapper 86 is located in the installation cavity 8.

[0048] When the connecting rod 105 is close to the top of the second W-shaped groove 104, the adsorbent 107 contacts the printing head 53. When the connecting rod 105 is located at the bottom of the second W-shaped groove 104, the adsorbent 107 is separated from the printing head 53, so that the printing head 53 can be attached to different positions on the adsorbent 107. When the slide bar 93 is close to the rightmost end of the first W-shaped groove 94, the clapper 86 contacts the side wall of the printing head 53; when the slide bar 93 moves to the leftmost end of the first W-shaped groove 94, the clapper 86 is separated from the printing head 53.

[0049] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
