[0036] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0037] Example 1

[0038] like Figure 1-8 As shown, a printing apparatus for processing printed fabrics with a flattening function includes:

[0039] A frame 2 with a groove 1;

[0040] Several telescopic components 3 are installed on the frame 2, and the telescopic direction of the first telescopic component 3 is vertical.

[0041] The hot press plate 4 is located at the telescopic end of the first telescopic component 3. The hot press plate 4 moves in the groove 1 under the drive of the first telescopic component 3. After the hot press plate 4 is powered on, it generates heat. The first telescopic component 3 drives the hot press plate 4 to move downward and press the heat transfer paper and the fabric, so that the pattern on the heat transfer paper is transferred to the surface of the fabric. The printing operation is completed by taking the fabric out from the groove 1.

[0042] A rotating component is mounted on the frame 2; the rotating component can be a rotating shaft, which not only supports the placement plate 5, but also drives the placement plate 5 to rotate along the axis of the rotating shaft.

[0043] The placement plate 5 is located on the rotating part, and the center of the placement plate 5 coincides with the center of the rotating part; two areas are formed on the placement plate 5, namely, a dual station, which can place and flatten the fabric at the same time as printing.

[0044] The leveling assembly is mounted on frame 2;

[0045] The leveling assembly includes a support 6, an air supply component 7 mounted on the support 6, a second telescopic component 8 mounted on the support 6, a pressure plate 9 located at the telescopic end of the second telescopic component 8, a conveyor 10, and an air duct 11 and a scraper 12 located at the bottom of the conveyor 10. An air outlet pipe is provided between the air supply component 7 and the air duct 11. The air duct 11 is located between the scraper 12 and the pressure plate 9. The electronic components of the leveling assembly are controlled by a controller. The air supply component 7 can be an air compressor or a high-power fan, which can not only draw in air but also provide a strong airflow.

[0046] It should be noted that the placement plate 5 has two stations: station one, located within the groove 1 for hot pressing, and station two, located away from the groove 1. Before printing, the fabric is roughly laid out on the surface of station two, with one edge of the fabric aligned with the edge of the placement plate 5 away from the groove 1. The second telescopic component 8 is activated, which moves the pressure plate 9, conveyor 10, air duct 11, and scraper 12 downwards and closer to the fabric. When the pressure plate 9 contacts the fabric, it stops moving, and the pressure plate 9 and placement plate 5 press one side of the fabric firmly. Then, the conveyor 10 is activated, moving the air duct 11 and scraper 12 closer to the frame 2. During the movement, the scraper 12 flattens the fabric, smoothing out any folds. After the scraper 12 initially smooths the fabric, the air duct 11 passes the position smoothed by the scraper 12. The air supply component 7 provides strong air to the air duct 11 through the air outlet pipe. The strong air blown out by the air duct 11 acts on the fabric surface, causing the fabric to adhere tightly to the surface of the placement plate 5, thus completing the fabric smoothing. This continues until the air duct 11 moves to the other end of the second workstation, that is, to the middle of the placement plate 5. At this point, the fabric is completely smoothed. After smoothing is completed, the second telescopic component 8 shortens, moving the smoothing component away from the fabric. Then, the rotating component is rotated to make the placement plate 5 rotate horizontally, allowing the fabric to enter the groove 1.

[0047] Furthermore, the conveyor 10 is equipped with an air suction cylinder 13 at its bottom, and an air inlet pipe is provided between the air suction cylinder 13 and the air supply component 7. The bottom height of the air suction cylinder 13 is higher than the bottom height of the scraper 12. When the fabric is too large, it is easy for the fabric in the middle of the placement plate 5 to roll or fold during manual placement, making it difficult for the scraper 12 to flatten the multiple folds. When the air supply component 7 intakes air through the air suction cylinder 13, a negative pressure is formed at the opening of the air suction cylinder 13, which sucks up the fabric, thus creating a height difference in the fabric. This height difference causes the fabric that is not sucked up and is in the forward direction of the air suction cylinder 13 to droop naturally. During the natural drooping process, the fabric can naturally stretch out, reducing the rolling and folding of the fabric, thereby allowing the fabric to be laid out better.

[0048] Furthermore, the suction cylinder 13 includes a cylinder body 14 and a cylinder head 15 sleeved within the cylinder body 14. A return spring 16, an electromagnet 17, and an iron plate 18 are provided between the cylinder head 15 and the cylinder body 14. The iron plate 18 is located on the cylinder head 15, and the electromagnet 17 is located on the cylinder body 14. When the electromagnet 17 is activated, it attracts the iron plate 18 on the cylinder head 15, causing the cylinder head 15 to displace relative to the cylinder body 14 and enter the cylinder body 14, thereby shortening the length of the suction cylinder 13. The shortened length of the suction cylinder 13 increases the height at which the fabric is lifted, further enhancing the stretching effect brought by the natural drape of the fabric. Because the suction cylinder 13 is telescopic, the opening of the cylinder head 15 can contact the fabric when the electromagnet 17 is not activated, allowing the suction cylinder 13 to properly lift the fabric and avoiding failure to lift the fabric due to excessive distance between the suction cylinder 13 and the fabric. The return spring 16 allows the cylinder head 15 to be automatically pulled out of the cylinder body 14, ensuring that the suction cylinder 13 can be reused.

[0049] Furthermore, the cylinder head 15 is provided with a main suction surface 21 and two side suction surfaces 22. The main suction surface 21 is located in the middle of the two side suction surfaces 22 and faces the fabric. When the fabric is too thick, it will block the opening of the cylinder head 15, thereby reducing the airflow of the air supply component 7. By providing the main suction surface 21 and the side suction surfaces 22, when the main suction surface 21 is in contact with the fabric, the side suction surfaces 22 can normally intake air, thereby ensuring the normal operation of the air supply component 7. Thin fabrics do not affect the normal air intake of the suction cylinder 13. Both the main suction surface 21 and the side suction surfaces 22 are provided with grilles to prevent thin fabrics from being sucked into the suction cylinder 13.

[0050] Furthermore, the cylinder head 15 is provided with two tracks 23, each track 23 is provided with a moving bar 24, and each moving bar 24 is provided with a connecting rod 25 pointing towards the conveyor 10 at the ends away from each other. The end of the connecting rod 25 away from the moving bar 24 is provided with a wheel 26. A spring 27 is provided between the moving bar 24 and the corresponding connecting rod 25. Each moving bar 24 is provided with several scraper strips 28 along its own length direction. The scraper strips 28 are arc-shaped and the end of the scraper strip 28 away from the moving bar 24 is bent towards the side of the fabric.

[0051] The conveyor 10 is equipped with two guide rails 29, the surfaces of which are wavy. When the suction cylinder 13 shortens, it drives the moving bar 24 and the connecting rod 25 to rise, causing the roller 26 on the connecting rod 25 to rise and enter the height of the guide rail 29. When the suction cylinder 13 moves, the roller 26 moves on the surface of the guide rail 29, driving the connecting rod 25 and the moving bar 24 to move. Under the combined action of the first spring 27, the moving bar 24 can reciprocate laterally. When the moving bar 24 moves, it drives the scraper 28 to move. When the scraper 28 moves away from the center of the fabric, it can pull the fabric towards the connecting rod 25, which can further flatten the folded fabric. The arc-shaped scraper 28 has a small pulling effect on the fabric when it is close to the center of the fabric, and will not cause secondary folding of the fabric. Under the reciprocating scraping of the scraper 28, the folds of the fabric are further reduced, ensuring that the fabric can be laid flat smoothly.

[0052] Furthermore, the air duct 11 includes a cylinder body and several partition plates 30 disposed within the inner cavity of the cylinder body. The inner cavity of the air duct 11 forms several independent spaces 31 through the partition plates 30. The partition plates 30 are divided into left and right parts in the middle of the air duct 11. The partition plates 30 in both parts are inclined and the inclination directions of the two parts are opposite so that the air blown out of the air duct 11 is inclined towards both ends of the air duct 11. In order to ensure that the airflow blown out of the air duct 11 acts evenly on the fabric, multiple partition plates 30 are provided and connected between the air duct 11 and the air outlet pipe by a fork pipe (the suction pipe 13 also adopts the suction method of the fork pipe to ensure the uniformity of airflow). Each fork pipe corresponds to an independent space 31, so that the airflow provided by the air supply component 7 can enter the independent space 31 evenly and blow onto the fabric. The inclined arrangement of the partition plates 30 can make the airflow blown out of the air duct 11 blow towards the side of the fabric, creating a scraping effect on the fabric, which can further make the fabric adhere tightly to the surface of the placement plate 5.

[0053] Furthermore, the first telescopic component 3 and the second telescopic component 8 are one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0054] Example 2

[0055] The suction cylinder 13 includes a cylinder body 14 and a cylinder head 15 fitted inside the cylinder body 14. A baffle plate 19 is provided inside the cylinder head 15, and the baffle plate 19 has several air holes 20. During the process of suction, the suction cylinder 13 draws in gas through the baffle plate 19 and into the air intake pipe through the air holes 20. The baffle plate 19 creates resistance to the passing gas, and the reaction force of the gas on the baffle plate 19 causes the baffle plate 19 to move, thereby driving the cylinder head 15 into the cylinder body 14, achieving the retraction of the suction cylinder 13. When air intake stops, the cylinder head 15 extends out of the cylinder body 14 under the action of gravity, completing the return of the suction cylinder 13 to its original position.

[0056] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
