It has the advantages of strong carrying capacity and wide adaptability. It is widely used in the transportation and storage of bulk materials in various industries.

[0003] Disadvantages of existing container bag support grippers:

[0004] Low operating efficiency: The traditional container bag opening jaw operation method is cumbersome and requires manual opening of the bag mouth one by one, which is time-consuming and inefficient. This method not only increases the workload of the staff, but also reduces the efficiency and accuracy of the operation.

[0005] Poor stability: Traditional bag-holding grippers lack effective stability control measures during operation, which can easily cause the mouth of the container bag to shift, deform, or fall off, affecting the safety and stability of the operation and increasing the risk of accidents.

[0006] Low precision: Due to the lack of precise bag opening control mechanism, traditional container bag opening grippers are often unable to accurately open the bag opening, which can easily lead to uneven or misaligned bag openings, affecting the accuracy and effectiveness of the operation.

[0007] Therefore, this invention proposes a bag support clamp for a container bag to solve the above problems. Utility Model Content

If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0049] Please refer to the instruction manual Figure 1-Figure 6 The utility model provides an implementation method of a bag support clamp for a container bag as follows:

[0050] Fixed platform 1: As the basic supporting structure of the entire bag holding clamp, fixed platform 1 is located on the top of the entire device and is used to install and fix other components.

[0051] Mounting frames 2: A pair of longitudinally parallel mounting frames 2 are located below the fixing platform 1 and are used to support and position the bag support assembly 6.

[0052] The transverse bag-supporting driving mechanism 3 is installed inside the fixed platform 1, and is composed of a driving motor 31 and a first driving screw 32. The driving motor 31 is installed at the right center of the fixed platform 1, and its output end is connected to the right end of the first driving screw 32. The first driving screw 32 is distributed transversely at the center of the fixed platform 1, and the first screw sleeves 33 are respectively threaded at both ends. The bottom wall of the first screw sleeve 33 is fixedly connected to the top center of the same side mounting frame 2. The first driving screw 32 is driven to rotate by the driving motor 31, thereby driving the first screw sleeves 33 on both sides to move synchronously to both sides, thereby driving the mounting frames 2 on both sides to move relative to each other, and driving the two bag-supporting assemblies 6 on both sides to slide from the center to both sides, thereby realizing transverse bag-supporting.

[0053] Bag-supporting assembly 6: A pair of bag-supporting assemblies 6 distributed in parallel front and back are arranged under each side mounting frame 2. Each bag-supporting assembly 6 includes a claw body 61 with a hollow interior. A vacuum pump 62 is installed on the outer side of the top end of the claw body 61. The vacuum end of the vacuum pump 62 is connected to the claw body 61 and passes through the inside of the claw body 61. A negative pressure adsorption port 63 is arranged on the outer side of the bottom end of the claw body 61 to adsorb the bag opening during the bag-supporting process to prevent it from falling off.

[0054] The longitudinal bag-supporting driving mechanism 5 is installed inside the mounting frame 2 and is composed of a dual-axis driving motor 51 and a second driving screw 52. The dual-axis driving motor 51 is installed in the center of the mounting frame 2, and its front and rear output ends are connected to the second driving screw 52. The second driving screw 52 is respectively threaded with a second screw sleeve 53. The bottom tube wall of the second screw sleeve 53 is respectively fixedly connected to the top of the front and rear bag-supporting assemblies 6 on the same side. The second driving screw 52 is driven to rotate by the dual-axis driving motor 51, thereby driving the second screw sleeve 53 on the same side to slide outward, thereby driving the front and rear bag-supporting assemblies 6 on the same side to move outward, thereby realizing longitudinal bag-supporting.

[0055] Guide assembly 4: Guide assemblies 4 are provided at the front and rear sides of the horizontal bag-supporting driving mechanism 3 at the bottom of the fixed platform 1. The guide assembly 4 includes a laterally distributed guide rod 41 and guide sleeves 42 correspondingly slidably sleeved on the left and right ends of the guide rod 41. The bottom tube walls of the guide sleeves 42 on both sides are respectively fixedly connected to the same side ends of the tops of the mounting frames 2 on both sides, so as to guide and limit the trajectory of the mounting frames 2 during lateral movement.

[0056] How it works

[0057] Make sure that the fixing table 1 is in a stable state and the mounting bracket 2 is in the correct position.

[0058] Check the working status of the transverse bag-supporting driving mechanism 3 and the longitudinal bag-supporting driving mechanism 5 to ensure that there are no faults or obstacles.

[0059] Horizontal bag support operation:

[0060] The driving motor 31 is started to make the first driving screw rod 32 start to rotate.

[0061] The rotation of the first driving screw 32 drives the first screw sleeve 33 to move to both sides, causing the mounting bracket 2 to move outward.

[0062] The movement of the mounting frame 2 causes the bag-supporting assembly 6 to slide in the transverse direction, thereby completing the operation of supporting the bag transversely.

[0063] Longitudinal bag support operation:

[0064] The dual-axis driving motor 51 is started to make the second driving screw 52 start to rotate.

[0065] The rotation of the second driving screw 52 drives the second screw sleeve 53 to slide outward, causing the two bag-supporting assemblies 6 on the same side to move in the front-to-back direction.

[0066] At the same time, during the bag-holding process, the vacuum pump 62 on the claw body 61 forms a negative pressure inside the claw body 61. At this time, a negative pressure is formed at the negative pressure suction port 63, thereby improving stability during the bag-holding process and effectively preventing the container bag from falling off.

[0067] This movement enables the bag-stretching assembly 6 to complete the operation of longitudinally strut the bag.

[0068] Thereby completing the operation of fully opening the mouth of the container bag.
