Description

Technical Field

[0001] The invention relates to the field of spraying facilities, in particular to a surface spraying device for producing Teslin cloth. Background Art

[0002] Teslin cloth is a special textile produced by shuttleless machine, which is made of composite yarn with special covering structure. The core of this yarn is made of high-strength polyester industrial filament, and the skin is PVC material with anti-aging and UV radiation. During the production process of Teslin mesh cloth, some coatings are often sprayed on the Teslin mesh cloth to improve product quality.

[0003] However, when the existing spraying device is spraying the Teslin mesh, due to the small mesh pores on the Teslin mesh, it is difficult for the paint to penetrate into the pores during the spraying process, resulting in a large spraying dead angle, that is, the Teslin mesh cannot be fully sprayed, resulting in a poor spraying effect.

The two pulling jaws are respectively attached to the opposite surfaces of the two top caps, and a stretching spring is wrapped around the outer side of the limiting column. The two ends of the stretching spring are respectively fixed to the opposite surfaces of the two pulling jaws, and a connecting frame is fixedly installed on the side of the two top caps, and the side of the connecting frame is fixed to the claw seat.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The servo motor drives the rotating ear to rotate, which can drive the reciprocating plate to move, so as to push the upper tooth plate, so that the upper tooth plate can move downward, and then drive the pulling roller on the roller seat to move downward, so as to pull the tensioned Textilene mesh downward, so that the pores on the Textilene mesh can be opened longitudinally, so as to facilitate the coating to be sprayed into the pores on the Textilene mesh, thereby reducing the spraying dead angle and improving the spraying effect.

[0014] 2. When the upper tooth plate moves downward, it will also drive the lower tooth plate upward through the gear, and then drive the concave frame upward to push the concave seat, so that the concave seat moves up to the push wheel. At this time, the pulling roller, driven by the upper tooth plate, just pulls the pores on the textilene mesh longitudinally. Then the upper tooth plate continues to move downward to drive the concave frame to continue to move upward, and then drive the concave seat to continue to move upward to push the push wheel, so that the push wheel can roll along the bevel on the concave seat, so that the two pulling claws can gather to clamp the edge of the textilene mesh. The positioning ear is placed on the T-rail to keep the T-rail still, and then the concave frame continues to move upward to drive the push plate to push the sliding sleeve so that the sliding sleeve can slide on the T-rail, thereby driving the concave seat to move to push the claw seat, so that the pulling claw can move horizontally, so as to pull the Teslin mesh horizontally, so that the pores on the Teslin mesh can be stretched horizontally, so that the pores on the Teslin mesh can be fully stretched under the double pulling in the horizontal and vertical directions, so as to further reduce the spraying dead angle and improve the spraying effect.

[0015] 3. When the Textilene mesh is pulled apart longitudinally, the downwardly moved roller seat just presses against the positioning cap, so that the pulling roller remains stationary. At the same time, the compression spring contracts and deforms, so that the upper tooth plate continues to move downward for the lateral pulling operation without being hindered. This ensures that after the Textilene mesh is pulled apart longitudinally, the pulling roller will not continue to pull the Textilene mesh longitudinally during the subsequent lateral pulling, thus avoiding the damage of the Textilene mesh due to excessive pulling, thereby effectively ensuring the protection of the Textilene mesh during spraying.
