[0031] A vertical groove 3 is provided at the lower side of the sleeve 13, a slider 31 is slidably provided in the vertical groove 3, a second U-shaped frame 32 located directly below the first U-shaped frame 2 is fixed to the slider 31, a second bearing plate 33 is provided in the second U-shaped frame 32, and a lifting assembly is provided on the left side of the slider 31;

[0032] The lifting assembly includes an annular groove 122 formed on the side wall of the column 12, a guide block 311 extending into the annular groove 122 is fixed to the slider 31, an inverted V-shaped groove 123 is formed on the upper left end of the annular groove 122, and the inverted V-shaped groove 123 corresponds to the position of the arc groove 121;

[0033] The side wall of the sleeve 13 is connected with an elastic telescopic rod 34, and the upper end of the elastic telescopic rod 34 is connected to the second bearing plate 33;

[0034] A cavity 4 is provided in the middle of the two first bearing plates 21, and a plurality of air holes 41 connected to the cavity 4 are provided on the upper side of the first bearing plates 21. A mounting groove 42 is provided on the lower side of the column 12, and an air suction pump 43 is installed in the mounting groove 42. A semicircular groove 44 is provided at the upper end of the column 12, and the air inlet end of the air suction pump 43 is connected to the semicircular groove 44. Air inlet pipes 45 are provided on both the front and rear sides of the upper end of the sleeve 13, and the two air inlet pipes 45 are respectively connected to the two first bearing plates 21. Air ducts 46 are provided at the rotating shaft and the center of the first gear 23, and the air duct 46 connects the air inlet pipe 45 with the cavity 4.

[0035] In the initial state, the two first supporting plates 21 are arranged front and back, and the staff stands in front of the machine 1, places the first fabric to be coated with glue on the first supporting plate 21 on the front side, and places the second fabric on the second supporting plate 33, and then drives the sleeve 13 to rotate counterclockwise through the driving component until the first supporting plate 21 carrying the fabric moves to the bottom of the screen printing machine 11. At this time, the air inlet pipe 45 connected to the first supporting plate 21 is connected to the semicircular groove 44, and the air inlet pipe 45 connected to the front first supporting plate 21 is not connected to the semicircular groove 44. The air suction pump 43 in the mounting groove 42 is started, and the air suction pump 43 draws the outside air through the air hole 41, the cavity 4, the air duct 46, the air inlet pipe 45 and the semicircular groove 44 to finally enter the air suction pump 43. The bottom of the column 12 is provided with a plurality of air outlet holes connected to the mounting groove 42, so that the air suction pump 43 will generate suction to absorb the first fabric on the first supporting plate 21 to prevent the first fabric from shifting in position during the gluing process;

[0036] During the gluing process of the screen printing machine 11, the staff can load the material on the first supporting plate 21 and the second supporting plate 33 at the front side. After the gluing work is completed on the first fabric, the driving assembly drives the sleeve 13 to rotate counterclockwise, and the push rod 27 corresponding to the first supporting plate 21 moves to the arc groove 121. The elastic force of the first spring 26 pushes it into the arc groove 121, and the slide plate 25 drives the rack 24 to move, and by meshing with the first gear 23, the first supporting plate 21 is driven by the rotating shaft. The plate 21 is turned 180 degrees. Under the suction of the suction pump 43, the first fabric will not fall down. It continues to rotate, and the guide block 311 will move into the inverted V-shaped groove 123 in the annular groove 122. Then, the elastic force of the elastic telescopic rod 34 will push the second supporting plate 33 upward, which will drive the slider 31 to slide upward in the vertical groove 3. The guide block 311 will also move upward to the upper end of the inverted V-shaped groove 123, so that the second fabric on the upper side of the second supporting plate 33 moves upward and fits the first fabric after glue coating. The elastic force of the flexible telescopic rod 34 will make the first fabric fit tightly with the second fabric, the sleeve 13 continues to rotate, the guide block 311 will contact the side wall of the inverted V-shaped groove 123, thereby pushing the elastic telescopic rod 34 to compress, and then driving the second bearing plate 33 to move downward. At this time, the air inlet pipe 45 connected to the first bearing plate 21 at this position will leave the upper end of the semicircular groove 44, and the first bearing plate 21 will not generate suction. The first fabric and the second fabric will be on the second bearing plate 33, and the guide block 311 will move to the ring again. After the first support plate 21 is in the arc groove 122, the push rod 27 will also contact the inclined surface of the front end of the arc groove 121, and the push rod 27 will be pushed to move, which will drive the first support plate 21 to flip 180 degrees and reset, and the push rod 27 will abut against the side wall of the column 12, and finally the first support plate 21 and the second support plate 33 will move back to the front side of the machine 1, and the staff will remove the two fabrics coated with glue and bonded on the second support plate 33, and place the new first fabric and the second fabric on the first support plate 21 and the second support plate 33;

[0037] With this design, after the first fabric on the first carrier plate 21 is coated with glue, the sleeve 13 rotates and drives it to move to the front side, which can first drive the first carrier plate 21 to rotate 180 degrees, and then the second carrier plate 33 moves upward, so that the first fabric and the second fabric can be bonded together, without the need for workers to manually bond the first fabric and the second fabric, and the degree of automation is high;

[0038] By setting up two sets of front and rear bearing components, the fabric can be continuously coated with glue. During the process of coating the fabric, the staff can operate the upper and lower fabrics on the front bearing components, thereby realizing continuous production and improving production efficiency;

[0039] The air inlet pipe 45 connected to the first supporting plates 21 on both sides of the front side is located at the front and rear sides of the sleeve 13, and the semicircular groove 44 on the upper end of the column 12 is arranged on the rear side. When the sleeve 13 rotates, when the supporting plate 21 rotates to the rear side, the air inlet pipe 45 can be connected with the semicircular groove 44, and the first supporting plate 21 can generate suction to adsorb the fabric. In this way, after the first supporting plate 21 is turned 180 degrees, the first fabric can be prevented from falling downward. After the first fabric and the second fabric are attached, the air inlet pipe 45 will also be separated from the semicircular groove 44, and the first supporting plate 21 loses the suction force on the first fabric. By changing the position of the air inlet pipe 45 and the semicircular groove 44, the fabric can be automatically adsorbed.

[0040] The air passage 46 is disposed at the center of the rotating shaft and the first gear 23 . When the rotating shaft and the first gear 23 rotate, air can normally flow from the cavity 4 into the air inlet pipe 45 through the air passage 46 .

[0041] The elastic telescopic rod 34 includes a hollow tube 341 connected to the sleeve 13, a sliding rod 342 is slidably arranged in the hollow tube 341, a second spring 343 is arranged between the lower end of the sliding rod 342 and the bottom wall of the hollow tube 341, and the upper end of the sliding rod 342 is connected to the second bearing plate 33;

[0042] The slide bar 342 slides in the hollow tube 341 . When the guide block 311 moves into the inverted V-shaped groove 123 , the elastic force of the second spring 343 pushes the slide bar 342 to move upward, thereby driving the second bearing plate 33 to move upward.

[0043] The driving assembly includes a ring gear 131 fixed at the bottom of the sleeve 13. The machine 1 is equipped with a motor 101. The output shaft of the motor 101 is connected to a second gear 102 meshing with the ring gear 131. Starting the motor 101 drives the second gear 102 to rotate, and the sleeve 13 can be rotated through the ring gear 131 meshing therewith.

[0044] The second carrying plate 33 is slidably arranged in the second U-shaped frame 32, a multi-stage telescopic rod 5 is arranged between the elastic telescopic rod 34 and the sleeve 13, a third spring 51 is sleeved on the outer side of the multi-stage telescopic rod 5, a circular groove 52 is opened on the upper side of the machine 1, a sliding guide rod 53 located in the circular groove 52 is fixed to the bottom of the elastic telescopic rod 34, an extension groove 54 is arranged on the front side of the circular groove 52, and the right side wall of the extension groove 54 is arc-shaped;

[0045] When the second bearing plate 33 is at the rear side, the sliding guide rod 53 is located in the circular groove 52, and the second bearing plate 33 is located in the second U-shaped frame 32. Then, the second bearing plate 33 is located directly below the first bearing plate 21, and the third spring 51 is in a compressed state. When the second bearing plate 33 moves to the front side, when the sliding guide rod 53 moves into the extension groove 54, the elastic force of the third spring 51 will push the elastic telescopic rod 34 to move forward, and the second bearing plate 33 slides forward in the second U-shaped frame 32. In this way, the second bearing plate 33 moves forward for a distance and will be aligned with the first bearing plate 21. 1, which can facilitate the staff to place the fabric, and avoid the problem that the second carrying plate 33 is located directly below the first carrying plate 21, which makes it inconvenient to place the fabric. The right side wall of the extension groove 54 is arc-shaped. When the sleeve 13 rotates, the sliding guide rod 53 will enter the circular groove 52 along the arc-shaped wall of the extension groove 54, so that the second carrying plate 33 is located directly below the first carrying plate 21 again; the multi-stage telescopic rod 5 is used to connect the sleeve 13 and the hollow cylinder 341 of the elastic telescopic rod 34, and can drive the hollow cylinder 341 to rotate synchronously when the sleeve 13 rotates, and can meet the forward and backward movement of the hollow cylinder 341.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
