Description

Technical Field

[0001] This application relates to the field of FIBC (Flexible Intermediate Bulk Container) production technology, and in particular to an automatic FIBC tipping mechanism. Background Technology

[0002] FIBCs, as an important type of container, are widely used for transporting powdery, granular, and lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals. During the production of FIBCs, a coating is often applied to the inside to meet specific functional requirements, making the bag-turning operation an essential step.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist:

[0004] First, the existing FIBCs are generally large in size. Manually turning the bags requires a lot of time and effort to turn the heavy and bulky FIBCs, which is labor-intensive and inefficient, making it difficult to meet the needs of large-scale production.

[0005] Secondly, during the process of turning over the FIBCs, improper operation may damage the surface of the FIBCs, turning them into defective products, affecting product quality, and increasing production costs.

[0006] To address the aforementioned problems, the inventors have proposed an automatic bag-turning mechanism for container bags, which solves these issues. Utility Model Content

[0007] In order to improve the problems of existing devices being inconvenient for turning bags and easily damaging FIBCs during the turning process, the purpose of this utility model is to provide an automatic bag turning mechanism for FIBCs.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a fixing mechanism, can clamp the edge of the bag opening of the container bag through the first rubber pad and the second rubber pad in the fixing mechanism, and can cooperate with the internal blowing mechanism through the first electric telescopic rod to make bag turning more convenient.

[0012] 2. This utility model, by setting an internal blowing mechanism, can drive the air outlet block to rise through the lifting cylinder, thereby initially turning the container bag.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-3 As shown, this utility model provides an automatic bag-turning mechanism for container bags, including a base plate 1, which serves as a support member to support the device.

[0020] Multiple fixing mechanisms 2 and an internal blowing mechanism 3 are fixedly installed on the top surface of the base plate 1. The fixing mechanisms 2 can fix the container bag, and the internal blowing mechanism 3 can turn the container bag over.

[0021] The fixing mechanism 2 includes a support rod 26, which is fixedly installed on one side of the top surface of the base plate 1. The top surface of the base plate 1 is provided with a protrusion, and multiple support rods 26 are fixedly installed on the top surface of the protrusion. The protrusion can create a height difference between the support rod 26 and the internal blowing mechanism 3, which makes it easier to turn the container bag over.

[0022] A first electric telescopic rod 27 is fixedly installed inside the support rod 26. A support block 28 is fixedly installed at the telescopic end of the first electric telescopic rod 27, so that the first electric telescopic rod 27 drives the support block 28 to rise and fall. An adjustment plate 25 is fixedly installed on one side of the support block 28, and the support block 28 drives the adjustment plate 25 to rise and fall.

[0023] The cross-sectional shape of the adjusting plate 25 is U-shaped. The adjusting plate 25 is slidably installed on the outer surface of the support rod 26. A through groove 24 is provided on one side of the support rod 26 to cooperate with the support block 28, so that the adjusting plate 25 is connected to the adjusting plate 25 through the through groove 24.

[0024] A second electric telescopic rod 21 and a first rubber plate 23 are fixedly installed on one side of the adjusting plate 25. A second rubber plate 22 that works in conjunction with the first rubber plate 23 is fixedly installed at the telescopic end of the second electric telescopic rod 21, so that the second electric telescopic rod 21 drives the second rubber plate 22 to move, thereby cooperating with the first rubber plate 23 to clamp the container bag.

[0025] The internal blowing mechanism 3 includes a ventilation block 37, a blower 36, and two lifting cylinders 35. The ventilation block 37, the blower 36, and the two lifting cylinders 35 are all fixedly installed in the middle of the top surface of the base plate 1 to prevent them from falling off.

[0026] The air outlet of the blower 36 is connected to the ventilation block 37. The ventilation block 37 has through holes inside, so that the airflow blown out by the blower 36 enters the bellows 34 through the through holes inside the ventilation block 37.

[0027] The top surface of the ventilation block 37 is connected to a corrugated pipe 34. An air outlet block 32 is fixedly installed at the top of the corrugated pipe 34. The bottom end of the air outlet block 32 is fixedly connected to the corrugated pipe 34 through a flange. The airflow can be transported through the corrugated pipe 34 and blown out through the air outlet block 32.

[0028] Multiple air outlet holes 31 are provided on the top and sides of the air outlet block 32. The air outlet holes 31 can discharge airflow, thereby turning the container bag over.

[0029] A fixing plate 33 is fixedly installed on the outer surface of the air outlet block 32. The extension ends of the two lifting cylinders 35 are fixedly connected to the two sides of the bottom surface of the fixing plate 33, so that the two lifting cylinders 35 drive the fixing plate 33 to rise and fall, thereby driving the air outlet block 32 to rise and fall.

[0030] Working principle: First, the device is fixed using the base plate 1. Then, the sides of the bag opening are fixed by four fixing mechanisms 2. The second electric telescopic rod 21 is activated, which drives the second rubber plate 22 to move. The second rubber plate 22 is fixed to the side of the bag by the cooperation of the first rubber plate 23, and the bag is kept open.

[0031] Then, the two lifting cylinders 35 of the internal blowing mechanism 3 are activated, causing the lifting cylinders 35 to move the fixed plate 33. The fixed plate 33 then causes the air outlet block 32 to rise, pushing a groove out of the bottom of the container bag.

[0032] Simultaneously, the first electric telescopic rod 27 is activated, causing the first electric telescopic rod 27 to drive the support block 28 to move. The support block 28 slides inside the through groove 24 and drives the adjusting plate 25 to descend, causing the adjusting plate 25 to slide on the outer surface of the support rod 26, thereby causing the bag opening of the container bag to descend, so that it can cooperate with the lifting cylinder 35 to perform the initial bag turning.

[0033] Then start the blower 36 to blow out airflow. The airflow enters the corrugated pipe 34 through the through hole inside the ventilation block 37, and the corrugated pipe 34 delivers the airflow to the air outlet block 32 and blows it out through multiple air outlet holes 31, so that the container bag can be completely turned over.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
