[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] See Figure 1 As shown;

[0025] This embodiment discloses an automatic packaging device for polyester resin, including a packaging machine 1 on a polyester resin packaging production line, a conveyor roller 2 for conveying the packaged polyester resin, and a palletizer 3 located at the end of the conveyor roller 2. The conveyor roller 2 is located between the packaging machine 1 and the palletizer 3, and is used to convey the packaging bags loaded with polyester resin material in a laid-down state. After the polyester resin is synthesized and processed, the finished product is in granular form. During the packaging process, the packaging machine on the packaging production line opens the bag and feeds the material into the packaging bag, and then seals it. The sealed packaging bag is laid down and fed into the conveyor roller, which conveys the packaging bag to the palletizer for palletizing. The gripping part of a commonly used palletizer is a claw structure, which extends into the bottom of the packaging bag to support it when gripping the packaging bag. The conveyor roller 2 is equipped with a material position conversion mechanism, a preliminary flattening mechanism, and a full flattening mechanism in sequence along its conveying direction.

[0026] The material position conversion mechanism is used to transfer the material gathered at the bottom of the packaging bag to the top of the packaging bag so that the material inside the packaging bag can be flattened in the subsequent operation.

[0027] The preliminary flattening mechanism is used to push the material gathered at the top of the packaging bag toward the bottom of the packaging bag, which is equivalent to pushing a portion of the material gathered at the top of the packaging bag backward, thus achieving the initial flattening effect on the material;

[0028] The full flattening mechanism is used to flatten the material in the packaging bag by rolling on the upper surface of the packaging bag, and to make the material flat in the whole packaging bag, so as to balance the weight of the packaging bag as a whole, so as to facilitate the subsequent stacking machine operation.

[0029] Further, the material position conversion mechanism includes a protruding part 4 formed on the conveying roller 2, and the rollers in the conveying roller 2 are partially protruding from the mixed roller except the protruding part 4 to form an arc-shaped conveying route upwardly protruding.

[0030] Further, the packaging bag conveyed on the protruding part 4 is conveyed to the position of the downward slope section of the protruding part, and the material in the packaging bag is freely rolled from the position of the bottom end of the packaging bag to the position of the top end of the packaging bag.

[0031] Specifically, on the arc-shaped conveying route of the protruding part 4, the packaging bag first goes uphill, and then goes downhill in the subsequent process, and the free rolling of the granular polyester resin particles is used to move the material from the position of the bottom end of the packaging bag to the position of the top end of the packaging bag, and the complete material is converted in the position of the packaging bag.

[0032] Further, the preliminary flattening mechanism includes a first support 5 which is transversely arranged on the conveying roller 2, and a rotating shaft 6 which is parallel to the rollers in the conveying roller 2 is arranged on the first support 5, and the rotating shaft 6 is rotatably arranged on the first support 5 through a bearing, and three groups of first pressing rollers 7 are uniformly distributed along the circumferential direction of the rotating shaft 6.

[0033] Further, the first pressing rollers 7 rotate with the rotating shaft 6, and when all the two groups of first pressing rollers 7 rotate to the same height below the rotating shaft 6, the lowest height of the first pressing rollers 7 is equal to the height of the material when the packaging bag is laid flat and flattened.

[0034] Specifically, the rotating shaft 6 does not need to be driven to rotate, and only when the height of the material gathered in the packaging bag passes through the preliminary flattening mechanism, the material higher than the first pressing rollers 7 moves to drive the first pressing rollers 7 to rotate, and in the process of rotating the first pressing rollers 7, the first pressing rollers 7 at the lower height contact the protruding part of the packaging bag and push the material backward. Because the material is granular and flows easily, the first pressing rollers 7 can push the material to move in the packaging bag. And the rotating directions of the rotating shaft 6 and the first pressing rollers 7 are not limited, for example, when one of the two first pressing rollers 7 below the rotating shaft 6 is lifted by the protruding part of the packaging bag, the other one will also press downward on other positions of the packaging bag to flatten the material due to the rotation.

[0035] Further, the full flattening mechanism includes a second support 8 which is transversely arranged on the conveying roller 2, and a plurality of second pressing rollers 9 which are parallel to each other are arranged on the second support 8, and the second pressing rollers 9 are parallel to the rollers in the conveying roller 2.

[0036] Further, the lowest height of the second compression roller 9 is equal to the material height when the packaging bag is laid flat and flattened.

[0037] Specifically, the packaging bag is substantially flattened by the preliminary flattening mechanism, and finally the packaging bag is limited by the multiple second compression rollers 9 which are densely distributed and at the same height, so as to achieve the effect of completely flattening the material.

[0038] In the above technical scheme, the automatic packaging device for polyester resin has the following beneficial effects:

[0039] The conveying roller plays a role of conveying the packaging bag in the automatic packaging device for polyester resin, and through the material position conversion mechanism, the preliminary flattening mechanism and the full flattening mechanism arranged on the conveying roller, the packaging bag laid down is flattened during the movement with the conveying roller, the material in the packaging bag is flattened, the overall weight of the packaging bag is balanced, the subsequent stacking machine is convenient for stable operation, the stability of the packaging bag is convenient for the subsequent stacking machine to grasp, and the neatness of the stacking is also good.

[0040] The above only describes some exemplary embodiments of the utility model by way of illustration, without doubt, for ordinary skilled in the art, under the condition of not deviating from the spirit and scope of the utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be understood as limiting the scope of protection of the utility model claims.
