Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figures 1-4 , a woven - bag turning machine, including a bag - pushing device for placing a woven bag and pushing the bottom of the woven bag for turning the bag, and further including a bag - sleeving device arranged on one side of the bag - pushing device for sucking and expanding the opening of the woven bag and then moving to sleeve the bag. A bag - supporting device for supporting the sleeved bag and moving it forward and backward to expand the woven bag is installed on the side of the bag - sleeving device away from the bag - pushing device.

[0026] In this embodiment: The bag - pushing device includes a material - discharging table 101. A bag - pushing rod 102 is slidably installed on the material - discharging table 101. A first guide rail 104 is arranged below the bag - pushing rod 102. A first slider 103 is arranged between the first guide rail 104 and the bag - pushing rod 102. A first lead screw 105 is installed inside the first slider 103. One end of the first lead screw 105 is installed with a first motor 106. The bag - pushing end of the bag - pushing rod 102 is arc - shaped and is made of 204 stainless steel. The first motor 106 drives the first lead screw 105 to rotate, pushing the first slider 103 to drive the bag - pushing rod 102 to move along the first guide rail 104 under the support of the material - discharging table 101 towards the woven bag, thereby pushing the outer bottom of the woven bag for turning the bag;

[0027] In this embodiment: the bagging device includes a support frame 201, two linear guide rails 202 are symmetrically installed on the top of the support frame 201, a linear motor 203 is installed on the linear guide rail 202, a moving frame 204 is arranged between the two linear motors 203, two electric push rods 205 are symmetrically installed on the upper and lower sides of the moving frame 204, and a suction cup 206 is installed on the extended end of the electric push rod 205. The support frame 201 is made of 45# material, and the linear motor 203 is bolted to the support frame 201. The woven bag is placed flat on the unloading table 101 and made Its open end is located between the two suction cups 206, and then the two electric push rods 205 are extended to drive the two suction cups 206 to approach and suck the upper and lower sides of the opening of the woven bag. The linear motor 203 drives the woven bag sucked by the suction cups 206 to move along the linear guide rail 202 under the support of the support frame 201 through the moving frame 204. When the opening end of the woven bag just moves out of the unloading platform 101, the electric push rod 205 is shortened, so that the opening of the woven bag is opened through the suction cups 206. As the moving frame 204 moves, the woven bag will be covered on the outside of the bag-holding device;

[0028] In this embodiment: the bag-holding device includes a second guide rail 301, on which a forward and reverse threaded screw rod 302 is installed, and a second motor 303 is installed at the front end of the forward and reverse threaded screw rod 302, two second sliders 304 are symmetrically arranged on both sides of the forward and reverse threaded screw rod 302, and a support rod 305 is installed on the second slider 304, and two first pulleys 306 are symmetrically arranged on the upper and lower ends of the support rod 305 away from the second slider 304, and two second pulleys 307 are symmetrically arranged on the back sides of the two support rods 305. After the support rod 305 extends into the bottom of the woven bag, the second motor 303 drives the forward and reverse threaded screw rod 302 to rotate and push the second slider 304 to drive the support rod 305 to move back to back along the second guide rail 301 until the second pulley 307 presses against the front and rear sides of the woven bag to open the woven bag, and finally the bag-pushing rod 102 pushes the outer bottom of the woven bag to turn the woven bag under the rolling support of the first pulley 306 and the second pulley 307.

[0029] Working principle: Place the woven bag flat on the feeding table 101, and make its opening end located between the two suction cups 206. Then, extend the two electric push rods 205 to drive the two suction cups 206 to approach and suck the upper and lower sides of the opening of the woven bag. The linear motor 203 drives the woven bag sucked by the suction cups 206 to move along the linear guide rail 202 under the support of the support frame 201 through the moving frame 204. When the opening end of the woven bag just moves out of the feeding table 101, shorten the electric push rod 205, so as to open the opening of the woven bag through the suction cups 206. As the moving frame 204 moves, the woven bag will be sleeved outside the two support rods 305 until the support rods 305 extend into the bottom of the woven bag. At this time, make the second motor 303 drive the left-right threaded lead screw 302 to rotate to push the second slider 304 to drive the support rods 305 to move away from each other along the second guide rail 301 until the second pulleys 307 press against the front and back sides of the woven bag to open the woven bag; finally, the first guide rail 104 supports the first motor 106 to drive the first lead screw 105 to rotate to push the first slider 103 to drive the bag pushing rod 102 to move towards the woven bag, so as to push the outer bottom of the woven bag, and make the woven bag turn over under the rolling support of the first pulley 306 and the second pulley 307.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
