Detailed Description
The following detailed description of the present application is provided to illustrate the present application and should not be construed as limiting the scope of the present application, since numerous insubstantial modifications and adaptations of the present application will be apparent to those skilled in the art from the foregoing disclosure.
Example 1
As shown in fig. 1 to 3, a continuous automatic rolling device is used for automatically rolling continuous bags 1, and comprises two parallel brackets 2, wherein two conveying rollers 3 are rotatably arranged between the two brackets 2, the conveying rollers 3 are driven by a motor, and the rotation directions of the two conveying rollers 3 are opposite. The conveyor roller 3 is rotated to clamp and convey the end of the continuous bag 1 downward, and the coiled continuous bag 1 is mounted by a reel and kept rotated. The support 2 is provided with two folding assemblies which are arranged below the conveying roller 3 and are mirror-symmetrical and have intervals for passing the continuous bags 1.
Wherein, the book subassembly is including fixing locating on the support 2 and flexible end carries out flexible a extensible member 4 along vertical direction, and the flexible end of a extensible member 4 is fixed to be equipped with flexible end and carries out flexible No. two extensible members 5 along the horizontal direction, and the flexible end of No. two extensible members 5 is fixed to be equipped with the curved elastic component 6 that has the cavity. The two ends of the elastic piece 6 are far away from the second telescopic piece 5. The inner ring side wall of the elastic piece 6 is provided with a plurality of air suction holes 7 communicated with the cavity along the circumferential direction, and the cavity of the elastic piece 6 is connected with an air compressor 8 through an air pipe. The crimping assembly further comprises a stop 10 above the elastic element 6.
The flexible end of the second flexible piece 5 is provided with a blade 9 for cutting off the continuous bag 1, and the second flexible piece 5 drives the elastic piece 6 to be close to the bag mouth and simultaneously drives the blade 9 to be close to the continuous bag 1 so as to cut off the continuous bag 1.
It should be noted that, after the continuous bag 1 passes through the interval between the two elastic pieces 6 downwards, the movement is stopped, the second telescopic piece 5 drives the elastic pieces 6 to approach the continuous bag 1, after the two ends of the two elastic pieces 6 are contacted, the elastic pieces 6 deform until the elastic pieces 6 become straight plates, and at this time, the inner side walls of the elastic pieces 6 are completely contacted with the continuous bag 1. Then the air compressor 8 is started, the air suction end of the air compressor 8 sucks air, an electromagnetic valve is arranged at the connecting part between the air compressor 8 and the elastic piece 6 and used for controlling the suction force of the suction air, so that suction force is generated at the suction hole 7 of the elastic piece 6, and the elastic piece 6 has an adsorption effect on the continuous bag 1. When the two elastic pieces 6 are far away from each other, the bag mouth of the continuous bag 1 is driven to open, and the elastic pieces 6 gradually recover to be arc-shaped, so that the bag mouth is circular. After the bag opening is completely opened, the first expansion piece 4 drives the second expansion piece 5 to move upwards, so that the bag opening moves upwards. The mouth moves outside the stopper 10 when moving upward, so that the mouth forms an everting roll-over. The limiting piece 10 is smaller than the diameter of the bag mouth, and a certain gap is reserved between the continuous bag 1 and the limiting piece 10. At this time, the air compressor 8 stops working, and the continuous bag 1 is scraped downwards from the limiting piece 10 by the elastic piece 6 under the drive of the first telescopic piece 4, so that the continuous bag 1 and the elastic piece 6 are separated, and the continuous bag 1 falls freely.
Wherein, after the elastic members 6 contact the continuous bag 1, the continuous bag 1 is clamped, but the two elastic members 6 are not completely contacted (the elastic members 6 are not completely changed into straight plates), at this time, the blade 9 is not contacted with the continuous bag 1, and the length of the continuous bag 1 can be adjusted by continuously rotating the conveying roller 3, so that the control of the length of the continuous bag 1 can be realized.
Further, the limiting piece 10 is wavy from top to bottom, the limiting piece 10 is arc-shaped, and the axis of the limiting piece is vertical.
The flexible piece 11 of No. three that the horizontal direction was stretched out and drawn back is fixed to No. two flexible pieces 5 below, and the flexible end of No. three flexible pieces 11 is fixed to be equipped with the briquetting 12 that suits with locating part 10 outside profile, and when elastic component 6 drove the sack and upwards turn over and accomplish the book back No. three flexible pieces 11 drive briquetting 12 and be close to locating part 10, briquetting 12 have the recess of fluctuation, respond with the profile of locating part 10, can become continuous wavy crease with the book portion of continuous bag 1 pressure. The wavy folds facilitate the retention of the flap of the mouth and the rapid adjustment of the length of the flap in use.
Further, the flexible end of the first flexible member 4 is fixedly provided with a blanking pressing plate 13 positioned between the two limiting members 10, the first flexible member 4 drives the blanking pressing plate 13 to move downwards after the continuous bag 1 is folded, and the blanking pressing plate 13 forms downward extrusion force on the continuous bag 1 at the inner side of the folding part of the mouth of the continuous bag 1, so that the continuous bag 1 can be separated from the limiting members 10 more easily.
Further, two spray heads 14 are fixedly arranged on the support 2, the spray heads 14 are connected with the air compressor 8 through air pipes, and the air compressor 8 conveys gas to the spray heads 14 after the adsorption of the bag openings is completed. Because the continuous bags 1 are rolled together during transportation, in order to avoid the influence of the trafficability of the continuous bags 1 caused by curling during downward conveying, the spray heads 14 are arranged to spray air between the two limiting pieces 10, so that the end parts of the continuous bags 1 can pass along the interval parts between the two limiting pieces 10, and the problem that the end parts of the continuous bags 1 are blocked on the limiting pieces 10 to cause discontinuous work is avoided. Meanwhile, the gas sprayed by the spray head 14 acts on the inner side of the bag opening folded part, so that the continuous bag 1 can be separated more easily when the continuous bag 1 is separated from the limiting piece 10, and the problem that the continuous bag 1 is clamped on the limiting piece 10 is solved.
The first telescopic part 4, the second telescopic part 5 and the third telescopic part 11 are electric push rods.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
