Fig.10 A first abutment spring 34 is arranged between the wedge-shaped tooth plate 33 and the adsorption frame 2, and the wedge-shaped tooth plate 33 meshes with the incomplete gear 32. The incomplete gear 32 is rotated by moving the wedge-shaped tooth plate 33 to mesh, so that the L-shaped plate 31 arranged on the incomplete gear 32 can rotate as the incomplete gear 32 rotates, and the L-shaped plate 31 is stored on the side of the adsorption frame 2 to avoid affecting the adsorption of the plastic woven bag by the adsorption frame 2; the abutment component includes a wedge block 41 slidably connected to the adsorption frame 2, a second abutment spring 42 is arranged between the wedge block 41 and the adsorption frame 2, and a groove for the wedge block 41 to move is arranged on the adsorption frame 2, and the elastic force of the second abutment spring 42 drives the wedge block 41 to extend to the outside of the adsorption frame 2, and the front and back sides of the wedge block 41 away from the adsorption frame 2 are both arranged in an inclined shape.
[0046] Furthermore, the trigger member includes a wedge-shaped strip block 7 fixedly connected to the frame 1, and the wedge-shaped tooth plate 33 abuts against the wedge-shaped strip block 7 during the movement of the wedge-shaped tooth plate 33. The distance of the wedge-shaped strip block 7 needs to be slightly longer than the distance that the adsorption frame 2 continues to move downward to adsorb the plastic woven bag after the L-shaped plate 31 rotates, and the specific shape of the wedge-shaped strip block 7 can be referred to the attached manual. Figure 1 The blocking member includes a triangular block 8 fixedly connected to the machine frame 1, and the wedge block 41 abuts against the triangular block 8 during its moving stroke. The triangular block 8 is arranged above the wedge-shaped long strip block 7 so that the wedge-shaped long strip block 7 is separated from the wedge-shaped tooth plate 33.

The elastic coefficient of the connecting spring 6 is smaller than the elastic coefficient of the second abutting spring 42, so that when the second abutting spring 42 abuts the wedge block 41 and contacts the blocking member, the connecting spring 6 is deformed first, until the connecting spring 6 is fully stretched, the wedge block 41 pushes the second abutting spring 42 to deform, so that the wedge block 41 passes through the abutting member.

[0051] Specifically, the anti-wrinkle component includes an annular groove 131 and a limiting groove 132 provided in the frame 1, the annular groove 131 is connected to the limiting groove 132; a moving rod 133 is slidably connected in the annular groove 131, and the annular groove 131 is the movement track of the moving rod 133. For the specific shape of the annular groove 131, please refer to the appendix of the specification. Figure 3 A limit rod 134 is provided on the moving rod 133, and the limit rod 134 is connected to the moving rod 133 through a connecting mechanism, and the limit rod 134 can move horizontally corresponding to the moving rod 133. The two ends of the limit rod 134 are respectively fixedly connected with a scraper 135 and a track rod 138, and the track rod 138 is slidably connected in the limit groove 132. The limit groove 132 is the movement track of the track rod 138. The partial track of the limit groove 132 can be referred to in the appendix of the specification. Figure 7, the track rod 138 drives the limit rod 134 to move horizontally under the action of the limit groove 132, and the plastic woven bag can be scraped flat during the horizontal movement of the limit rod 134; a rotating rod 136 is rotatably connected to the machine frame 1, and a telescopic connecting rod 137 is fixedly connected to the rotating rod 136. The telescopic connecting rod 137 is slidably connected to the moving rod 133 through a slip ring, and the rotating rod 136 is synchronously driven with the rotating shaft of the conveyor belt 11 through the existing rotating mechanism to make the rotating rod 136 rotate, and through the mutual cooperation between the telescopic connecting rod 137, the moving rod 133, the limit rod 134, the track rod 138, the annular groove 131 and the limit groove 132, the scraper 135 is driven to move horizontally during the movement of the conveyor belt 11 to scrape the plastic woven bag flat.
[0052] In the solution further provided by the present invention, a support assembly for stacking plastic woven bags is also provided in the machine frame 1, and a limiter for limiting the support assembly is also provided on the machine frame 1; the support assembly can be limited by setting the limiter to avoid large-scale movement when the items on the support assembly are reduced, and the support assembly includes a plurality of elastic telescopic rods 141 fixedly connected to the machine frame 1, and the top ends of the plurality of groups of elastic telescopic rods 141 are fixedly connected to the same support plate 142, and the plurality of elastic telescopic rods 141 are evenly distributed on the support plate At the bottom of 142, a rectangular block 143 is slidably connected inside the support plate 142, a groove for the rectangular block 143 to move is provided inside the support plate 142, a limited helical tooth 144 is fixedly connected to one side of the rectangular block 143, and a push spring 145 is provided between the rectangular block 143 and the support plate 142; the limiting member is a wedge-shaped rack 15 provided on the machine frame 1, and the elastic force of the push spring 145 drives the limiting helical tooth 144 to engage with the wedge-shaped rack 15. The connection between the limiting helical tooth 144 and the wedge-shaped rack 15 can be referred to the appendix of the specification. Fig.11 .
[0053] Furthermore, an unlocking unit is provided in the support plate 142 for triggering the unlocking of the limiting bevel tooth 144 and the wedge-shaped rack 15. By providing the unlocking unit, the limitation between the limiting bevel tooth 144 and the wedge-shaped rack 15 can be released, so that it is convenient for manual control of the up and down movement of the support assembly; the unlocking unit includes an unlocking wedge rod 161 slidably connected to the support plate 142, one end of the unlocking wedge rod 161 is fixedly connected to a baffle 164, a limiting spring 162 is provided between the baffle 164 and the support plate 142, and an inclined groove 163 adapted to the unlocking wedge rod 161 is provided on the rectangular block 143. When the unlocking wedge rod 161 enters the inclined groove 163, the rectangular block 143 can be triggered to move to squeeze the push spring 145, so that the rectangular block 143 drives the limiting bevel tooth 144 to move to the inside of the support plate 142.
[0054] During operation, the baffle plate 164 on the support plate 142 is pushed to move toward the support plate 142 side, so that the wedge rod connected to the baffle plate 164 can enter the inside of the inclined groove 163, driving the rectangular block 143 to drive the limiting bevel gear 144 to move and separate from the wedge-shaped rack 15. At this time, a plastic woven bag that needs to be printed in a certain amount is placed on the support plate 142. The weight of the plastic woven bag will squeeze the elastic telescopic rod 141 at the bottom of the support plate 142 to cause it to deform. At this time, the thrust on the baffle plate 164 is released, so that the rectangular block 143, under the action of the thrust spring, drives the limiting bevel gear 144 to be stuck in the wedge-shaped rack 15.
[0055] By starting the first electric telescopic rod 51 on the machine frame 1, the first electric telescopic rod 51 works to push the support frame 52 downward, and through the action of the moving plate 53 and the connecting spring 6, the adsorption frame 2 is driven to move downward synchronously. When the adsorption frame 2 moves downward, the wedge-shaped tooth plate 33 arranged thereon will contact the wedge-shaped long strip block 7. At this time, the wedge-shaped long strip block 7 will push the wedge-shaped tooth plate 33 to move and squeeze the first abutting spring 34. During the movement, the wedge-shaped tooth plate 33 will engage with the incomplete gear 32 on the L-shaped plate 31 to rotate, and the incomplete gear 32 drives the L-shaped plate 31 to rotate. At this time, the adsorption frame 2 continues to move downward, driving the adhesive plate 21 to contact the top plastic woven bag piled on the support plate 142 and adsorb it. After the adsorption is completed, the first electric telescopic rod 51 moves upward, driving the adsorption frame 2 to drive the adsorbed plastic woven bag to move upward synchronously, and when the adhesive plate 21 adsorbs the plastic woven bag, the bottom of the plastic woven bag may be attached with a second When the suction frame 2 moves upward until the wedge block 41 is separated from the wedge-shaped strip block 7, the first abutment spring 34 returns to its original position, driving the moving wedge-shaped tooth plate 33 to reset. The reset of the wedge-shaped tooth plate 33 drives the rotating L-shaped plate 31 to reset and block the bottom of the plastic woven bag. At this time, the suction frame 2 will move to the triangular block 8, and the wedge block 41 on the suction frame 2 will be blocked by the triangular block 8, driving the first electric telescopic rod 51 to continue to extend, driving the support plate 142 and the moving plate 53 to move synchronously. At this time, the connecting spring 6 connected between the moving plate 53 and the suction frame 2 will be stretched. When the connecting spring 6 is stretched to a certain extent, the wedge block 41 in the suction frame 2 will abut against the second abutment spring 42 to deform, so that the wedge block 41 passes through the triangular block 8, and the connecting spring 6 quickly rebounds to drive the suction frame 2 and the plastic woven bag to shake, so that the plastic woven bags are separated, and the shaken-off plastic woven bags will fall on the L-shaped plate 31 for temporary storage.
[0056] By driving the first electric telescopic rod 51 to extend downward again, driving the adsorption frame 2 to continue to move downward, cooperating with the wedge-shaped long strip block 7, driving the L-shaped plate 31 to rotate and open, so that the shaken plastic woven bag can fall into the storage place. At this time, the first electric telescopic rod 51 moves up and separates from the wedge-shaped long strip block 7, but when it does not need to move to the height of the triangular block 8, the first electric telescopic rod 51 stops working and maintains the state before power failure, driving the second electric telescopic rod 54 to work, which can push the moving plate 53 at the bottom of the support frame 52 to move. The moving plate 53 drives the adsorption frame 2 and the adsorbed plastic woven bag to move synchronously through the connecting spring 6. When the adsorption frame 2 moves to the place where the material is to be unloaded under the action of the second electric telescopic rod 54, the protrusion 94 above the adsorption frame 2 will contact the oblique long rod 10, pushing the protrusion 94 to move downward. In this process, it is necessary to ensure that the elastic coefficient of the support spring 95 is less than the coefficient of the connecting spring 6. The protrusion 94 squeezes the support spring 95 to move downward and drives the cross plate 92 in the adsorption frame 2 to move downward synchronously through the slide bar 93. The downward movement of the cross plate 92 drives the multiple push columns 91 to move, and the plastic woven bag adhered to the adhesive plate 21 can be pushed down and separated from the adhesive plate 21. At this time, the second electric telescopic rod 54 drives the adsorption frame 2 to move in the opposite direction and reset.
[0057] The plastic woven bag separated from the adhesive plate 21 will fall onto the conveyor belt 11, and the conveyor belt 11 will convey the plastic woven bag. In the process of conveying, the rotating rod 136 rotates through the telescopic connecting rod 137 to drive the moving rod 133 to move along the annular groove 131, and the moving rod 133 drives the limiting rod 134 to move during the movement of the moving rod 133. At this time, the scraper 135 on the limiting rod 134 will contact the plastic woven bag, and when the scraper 135 contacts the middle of the plastic bag, the moving rod 133 will move with the movement of the plastic woven bag under the action of the rotating rod 136, the telescopic connecting rod 137, the moving rod 133 and the limiting rod 134. , and while the moving rod 133 drives the scraper 135 to move, the track rod 138 on the other end thereof will drive the moving rod 133 to move horizontally under the action of the limiting groove 132. The horizontal movement of the moving rod 133 can drive the scraper 135 to move on the surface of the plastic woven bag, so that the plastic woven bag can be scraped flat to avoid wrinkles in the plastic woven bag. The scraper 135 moves to the two ends of the plastic woven bag and squeezes the two ends until the plastic woven bag moves through the printing roller 12. After printing is completed, the moving rod 133 will move up under the action of the annular groove 131, so that the moving rod 133 drives the scraper 135 to separate from the plastic woven bag.
