Description

Technical Field

[0001] The utility model relates to the technical field of container bag processing equipment, in particular to a positioning mechanism of a container bag sewing device. Background Art

[0002] Container bags, also known as flexible container bags, ton bags, space bags, etc., are a kind of flexible transport packaging container. Equipped with a crane or forklift, it can realize containerized unit transportation. It is suitable for transporting bulk powdery and granular materials. It is widely used in the transportation and packaging of powdery, granular and blocky items such as food, grains, medicines, chemicals and minerals.

[0003] When producing bulk bags, the cut and formed bulk bag pieces need to be sewn to obtain finished bulk bags. When the sewing machine is operating, the bag mouth is generally fixed manually, and then the fixed bag mouth is sewn with the sewing machine. This sewing process is likely to result in unqualified products, and is time-consuming and labor-intensive. It is easy to cause damage to people's fingers for a long time. In addition, when sewing, it is necessary to manually push the bulk bag while sewing with the sewing machine, which is inefficient.

[0004] Therefore, the patent with publication number CN214418959U proposes a positioning structure for processing flexible container bags, which can position the flexible container bags to be processed to facilitate cutting and processing. The container bags are laid on the processing table and fixed by the positioning structure and the pressing plate. The sliding block can drive the pressing plate to move above the processing table, which is convenient for users. However, most container bags are made of soft plastic polypropylene, which is easy to wrinkle and become uneven during transportation. If the pressing plate is pressed down for positioning and then sewing without adjustment, it is easy to cause wrinkles and overlaps in the container bags, and even affect the sewing process, causing the container bags to overlap and sew. Utility Model Content

[0005] The utility model aims to provide a positioning mechanism for a container bag sewing device to solve the technical problem that the method of fixing and positioning by a pressing plate in the existing container bag sewing positioning mechanism easily causes wrinkles and overlaps of the container bag.

[0013] Preferably, the fixing plate is further provided with a plurality of groups of arc grooves for fixing the fixing rollers and the container bag sheets.

[0014] Preferably, the arc groove and the fixing groove are arranged in the same vertical direction; two groups of the arc groove and the fixing groove are arranged in total, which are respectively arranged at two ends away from the fixing rod and close to the fixing rod.

[0015] By adopting this technical solution, the container bag pieces are transported to the fixed plate. Under the action of the screw, the gear rotates to drive the sliding seat and the rotating shaft to slide on the slide rail. The rotating shaft rotates while sliding, and the rotating shaft drives the fixed roller to rotate and slide on the fixed plate. The fixed roller rotates from one side of the fixed plate to the other side. At the same time, as the fixed roller rotates, the compression belt is gradually unfolded to compress the rolled container bag pieces to prevent wrinkles again, and the container bag pieces are rolled to the other side to complete the flattening.

[0016] When turning to the other side, the rotating shaft enters the fixed groove, and the fixed roller enters the arc groove, and cooperates with the compression belt to fit and fix the container bag piece to the fixed plate, and avoids too large a fixed cover to affect the work of the sewing device on the surface of the container bag piece.

[0017] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0018] 1. The rotating shaft of the utility model drives the fixed roller to rotate from one side of the fixed plate to the other side. At the same time, as the fixed roller rotates, the pressing belt is gradually unfolded to press the rolled container bag piece to prevent wrinkling again, and the container bag piece is rolled to the other side to complete the flattening of the container bag piece;

[0019] 2. When the utility model rotates to the other side, the rotating shaft enters the fixed groove, and the fixed roller enters the arc groove, and cooperates with the compression belt to fix the container bag piece to the fixed plate, and avoids too large an area of ​​fixed covering to affect the work of the sewing device on the surface of the container bag piece.

[0033] In this embodiment, the limiting plate 15 is provided with a slide rail 5 for slidably connecting to the slide seat 4 and a top plate for rotatably connecting to the screw rod 6 .

[0034] In this embodiment, the fixing plate 1 also includes a fixing rod 3 for fixing one end of the container bag sheet. The fixing rod 3 is provided with a plurality of groups of compression belts 31 for fixing the middle part of the container bag sheet. The compression belt 31 is wound around one end away from the fixing rod 3 and connected to the fixing roller 2.

[0035] In this embodiment, the fixing plate 1 is further provided with a plurality of groups of arc grooves 13 for fixing the fixing rollers 2 and the container bag sheets.

[0036] In this embodiment, the arc groove 13 and the fixing groove 14 are arranged in the same vertical direction; two groups of the arc groove 13 and the fixing groove 14 are arranged, which are respectively arranged at two ends away from the fixing rod 3 and close to the fixing rod 3.

[0037] Example 2

[0038] The only difference between this embodiment and embodiment 1 is that, in this embodiment, the fixed plate 1 is further provided with a limit plate 15, and the end of the rotating shaft 21 of the fixed roller 2 away from the sliding groove 12 passes through the limit plate 15 and is connected to a sliding seat 4 for controlling the rotation and sliding of the fixed roller 2.

[0039] In this embodiment, the sliding seat 4 is further provided with a pulley 51 for slidably connecting with the sliding rail 5 .

[0040] Example 3

[0041] The only difference between this embodiment and the first embodiment is that, in this embodiment, the sliding seat 4 is provided with a gear 22 axially connected to the rotating shaft 21 , and the gear 22 is meshingly connected to the screw rod 6 .

[0042] Working principle and usage process:

[0043] By adopting this technical solution, the container bag pieces are transported to the fixed plate 1. Under the action of the screw 6, the gear 22 rotates to drive the sliding seat 4 and the rotating shaft 21 to slide on the slide rail 5. The rotating shaft 21 rotates while sliding, and the rotating shaft 21 drives the fixed roller 2 to rotate and slide on the fixed plate 1. The fixed roller 2 rotates from one side of the fixed plate 1 to the other side. At the same time, as the fixed roller 2 rotates, the pressing belt 31 is gradually unfolded to press the rolled container bag piece to prevent it from wrinkling again, and the container bag piece is rolled to the other side to complete the flattening of the container bag piece;

[0044] When rotating to the other side, the rotating shaft 21 enters the fixed groove 14, and the fixed roller 2 enters the arc groove 13, and cooperates with the clamping belt 31 to fit and fix the container bag piece to the fixed plate 1, and avoids too large fixed cover to affect the work of the sewing device on the surface of the container bag piece.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
