Description

Technical Field

[0001] This utility model belongs to the field of inner lining bag technology, specifically relating to a container bag inner lining bag forming device. Background Technology

[0002] Liner bags can be used inside FIBCs (Flexible Intermediate Bulk Containers). Existing liner bags are directly nested inside FIBCs. During unloading, the liner bag detaches from the FIBC and needs to be nested back in. This requires sewing the liner bag inside the FIBC. Existing liner bag installation involves turning the FIBC over so one side is facing up and sewing part of the liner bag onto it. This process is repeated, turning the FIBC over again to sew the remaining parts of the liner bag onto the FIBC, connecting the liner bag components. However, this process only sews part of the liner bag onto the FIBC at a time, requiring multiple operations to complete the liner bag's formation, resulting in low efficiency and cumbersome steps. Utility Model Content

[0003] The purpose of this utility model is to provide a container bag inner liner forming device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a container bag liner forming device, comprising: a support base, wherein movable columns are installed on the top of the support base in four directions, and levers inserted into the container bag are installed side by side on the inner sides of the four columns, and when the four levers move outward simultaneously, they are used to open the four corners of the container bag.

[0005] Preferably, the support base includes horizontal and vertical bars arranged in a cross shape, and each end of the top of the horizontal and vertical bars is equipped with a moving groove, and each moving groove is equipped with a moving mechanism that drives the corresponding column to move.

[0020] 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.

[0021] refer to Figure 1-2As shown, the present invention provides a container bag liner forming device, comprising: a support base, movable columns 4 installed on the top of the support base in four directions, and levers 5 inserted into the container bag installed side by side on the inner side of each of the four columns 4. When the four levers 5 move outward at the same time, they are used to open the four corners of the container bag.

[0022] Combination Figure 2 As shown, the support base includes a crossbar 2 and a longitudinal bar 3 arranged in a cross shape. Both ends of the top of the crossbar 2 and the longitudinal bar 3 are equipped with a movable groove 13, and each movable groove 13 is equipped with a movable mechanism that drives the corresponding column 4 to move.

[0023] As described above, using the support base, column 4, and lever 5 provided by this utility model, the support base forms a cross structure through the horizontal bar 2 and the vertical bar 3. The horizontal bar 2 and the vertical bar 3 provide installation positions for the four moving mechanisms. The moving groove 13 allows the column 4 to move on the corresponding horizontal bar 2 or vertical bar 3. When the four levers 5 are inserted into the container bag, the moving mechanism is activated, driving the four columns 4 to move outward simultaneously. Thus, the four levers 5 open the four corners of the container bag, making it easy for the inner liner bag to be installed manually in four directions of the container bag at the same time.

[0024] Furthermore, to facilitate the movement and adjustment of column 4, refer to Figure 2-3 As shown, the moving mechanism includes a lead screw 14 and a drive motor 1 that drives the lead screw 14 to rotate. The lead screw 14 is rotatably mounted in the moving groove 13. A moving block 10 that can move in the moving groove 13 is installed at the bottom end of the column 4. A threaded hole 12 that is screwed onto the lead screw 14 is opened through the moving block 10. A switch 9 that is electrically connected to the four drive motors 1 is installed on the crossbar 2 or the vertical bar 3. The lead screw 14 is rotatably mounted in the moving groove 13, and the column 4 is moved in the moving groove 13 through the threaded hole 12 on the moving block 10. The drive motor 1 can drive the lead screw 14 to rotate. At this time, the column 4 can be driven to reciprocate in the moving groove 13 through the worm gear principle, thereby adjusting the position of the lever 5. The drive motor 1 can be adjusted by the switch 9.

[0025] In this utility model, combined with Figure 3 As shown, each column 4 in this embodiment is equipped with a lifting mechanism on its top, which is used to drive the lever 5 to rise and fall.

[0026] Combination Figure 3 As shown, the lifting mechanism includes a telescopic rod 6, and a connector 7 is connected between the top end of the telescopic rod 6 and the top end of the lever 5. The top of the column 4 has a telescopic hole 11 facing downwards, and at least one end of the telescopic rod 6 is movably inserted into the telescopic hole 11.

[0027] As described above, in the lifting mechanism provided by this utility model, the telescopic rod 6 in the lifting mechanism is installed in parallel with the lever 5 through the connector 7. The telescopic rod 6 can be adjusted up and down on the column 4 through the telescopic hole 11. When the telescopic rod 6 is raised in the telescopic hole 11, it can drive the lever 5 to rise. At this time, the container bag is placed below the four levers 5. Then the telescopic rod 6 is lowered, so that the four levers 5 are inserted into the container bag. After the four levers 5 are unfolded outward, it is easy to open the container bag.

[0028] Furthermore, to facilitate the raising and lowering of the drive lever 5, refer to... Figure 3 As shown, a handle 8 for raising and lowering is also installed on the connector 7. The handle 8 is located on the side of the connector 7 away from the lever 5. The handle 8 allows for easy manual lifting of the connector 7, which in turn lifts the telescopic rod 6 through the telescopic hole 11, thereby lifting the lever 5.

[0029] Furthermore, to prevent the container bag from slipping on lever 5, refer to Figure 4 As shown, the lever 5 has anti-slip grooves 15 along the axial direction on its outer periphery, with the anti-slip grooves 15 facing the column 4. After the container bag is opened outward by the lever 5, the anti-slip grooves 15 on the lever 5 sink into the container bag, so that the container bag will not slide on the lever 5 during the installation of the inner liner bag.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
