Description

Technical Field

[0001] The utility model relates to the technical field of ton bag transportation equipment, and more specifically, to a novel gripper structure. Background Art

[0002] Ton bags, widely known as flexible bulk bags, loading bags or cofferdam bags, are not only indispensable medium-sized bulk containers in modern logistics, but also a powerful assistant for efficient containerized transportation. With its lightweight characteristics and good compatibility with cranes or forklifts, it greatly simplifies the loading and unloading process and reduces transportation costs, becoming an important bridge connecting producers and consumers. Ton bags are particularly widely used in many industries such as food, grains, medicine, chemicals, and minerals. Whether it is fine powdery substances such as flour and starch, or granular chemical raw materials, feed, or even large pieces of minerals, ton bags can provide safe and reliable packaging solutions. Its excellent sealing and durability ensure that the materials are transported safely. The quality of the ton bags is not affected, and the environmental pollution problems that may be caused by traditional packaging methods are also avoided. However, with the widespread application of ton bags in the field of transportation, a problem that cannot be ignored has gradually emerged. When the ton bags are filled with heavy materials, the woven slings on the top will often bend outward due to gravity in the absence of effective support. This phenomenon not only affects the overall aesthetics of the ton bags, but also brings considerable troubles during transportation. Due to the bending of the slings, it is difficult for operators to grab them quickly and accurately, which not only prolongs the loading and unloading time, but also may cause the transportation tools to be unable to start or drive normally due to the inability to stably fix the ton bags, thus affecting the smooth operation of the entire logistics chain. Therefore, it is necessary to improve and optimize them. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a novel gripper structure, which has the advantages of convenient gripping.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel gripper structure, including a mounting frame, four mobile frames are slidably installed on the top of the mounting frame, and a vertical mechanism is respectively arranged at the bottom of each of the mobile frames, and the vertical mechanism includes four fixed plates 1 and four fixed plates 2 fixedly installed at the bottom of the mobile frame, and the left sides of the corresponding fixed plates 1 and 2 are respectively fixedly installed with rotating rods, and the output shafts of the two rotating rods respectively penetrate the corresponding fixed plates 1 and 2, and motors are respectively fixedly installed on the output shafts of the two rotating rods, and the right ends of the two motors penetrate the two middle fixed plates 1 and 2 and are rotatably connected to the left sides of the rearmost fixed plates 1 and 2, and two sprocket wheels 1 are respectively fixedly sleeved on the outer walls of the two motors, and roller motors are respectively arranged in the middle of the four fixed plates 1 and the middle of the four fixed plates 2, and the vertical height values ​​of the two roller motors are inconsistent.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 6 As shown, the utility model provides a novel gripper structure, including a mounting frame 1, four mobile frames 2 are slidably mounted on the top of the mounting frame 1, and a vertical mechanism is respectively arranged at the bottom of each mobile frame 2, and the vertical mechanism includes four fixed plates 1 3 and four fixed plates 2 9 fixedly mounted on the bottom of the mobile frame 2, and rotating rods 5 are respectively fixedly mounted on the left sides of the corresponding fixed plates 1 3 and fixed plates 2 9, and the output shafts of the two rotating rods 5 respectively penetrate the corresponding fixed plates 1 3 and fixed plates 2 9, and motors 4 are respectively fixedly mounted on the output shafts of the two rotating rods 5, and the right ends of the two motors 4 penetrate the two middle fixed plates 1 3 and fixed plates 2 9 and are rotatably connected to the left sides of the rearmost fixed plates 1 3 and fixed plates 2 9, and two sprocket wheels 6 are respectively fixedly sleeved on the outer walls of the two motors 4, and roller motors 8 are respectively arranged in the middle of the four fixed plates 1 3 and the middle of the four fixed plates 2 9, and the vertical height values ​​of the two roller motors 8 are inconsistent (presenting a high and a low distribution).

[0021] Two sprockets 6 are fixedly mounted on the outer walls of the two motors 4, and these sprockets are connected to the subsequent transmission components through chains, forming an efficient and stable transmission chain. At the same time, in order to meet the needs of grabbing at different heights or angles, roller motors 8 are also set in the middle of the four fixed plates 1 3 and the four fixed plates 2 9, and the vertical height values ​​of the two roller motors are deliberately designed to be inconsistent. This design enables the gripper structure to have a more flexible and changeable grabbing ability in the vertical direction, and can easily cope with various complex working environments and grabbing tasks.

[0022] The staff will first carefully arrange the ton bags to be processed to ensure that they are safely placed in the special working area of ​​the device. Then, the staff will start the motor 4. The rotation of the motor 4 is transmitted to the sprocket 1 6 through the rotating rod 5. The sprocket 1 6 serves as the starting point of the transmission chain and is tightly engaged with the chain 7 to smoothly transmit the power to the sprocket 2 11. With the start of the sprocket chain transmission system, the two roller motors 8 begin to move towards each other according to the preset specific motion path. The outer walls of the two roller motors 8 are covered with a layer of plastic fiber with a specific hardness and length. When these fibers come into contact with the woven strips, they can generate sufficient friction to gradually guide and straighten the originally disordered woven strips to a vertical state. With the coordinated action of the two roller motors 8, the ton bag woven strips are effectively arranged into an orderly arrangement. When the woven strips are straightened to the appropriate position, the five-finger column 13 on the upper part of the device responds quickly as part of the existing mechanism, and accurately extends out and penetrates the gaps naturally formed between the ton bag woven strips after being pulled up, so that it can firmly clamp the woven strips to prevent them from loosening or deformation. After the fixation is completed, the staff can further process or transport the fixed woven strips according to specific work needs, making the subsequent processing smoother and more efficient.

[0023] Among them, the corresponding two fixed plates 1 3 are rotatably installed on one side close to each other and the corresponding two fixed plates 2 9 are rotatably installed on the groove side, and the outer walls of the four rotating shafts 10 are respectively fixedly sleeved with sprockets 2 11, and the outer walls of the corresponding sprockets 1 6 and sprockets 2 11 are wound with chains 7, and the outer walls of the four chains 7 are respectively fixedly installed with four L-shaped blocks 12, wherein the corresponding two L-shaped blocks 12 are respectively fixedly connected to the two sides of the corresponding roller motor 8.

[0024] By rotatably installing the rotating shaft 10 on the corresponding fixed plate 1 3 and the fixed plate 2 9, and fixing the sprocket 2 11 on the outer wall of the rotating shaft, together with the sprocket 1 6, an efficient transmission system is formed, which ensures the continuity and stability of power transmission, so that the roller motor 8 can move accurately according to the predetermined trajectory and speed, thereby improving the overall working efficiency.

[0025] The outer walls of the two roller motors 8 are respectively covered with plastic wool, and the material of the plastic wool is polypropylene.

[0026] By setting plastic wool made of polypropylene to cover the outer wall of the roller motor, flexibility and protection are added to the clamping process. Polypropylene material has good wear resistance, chemical resistance and certain elasticity. Since the plastic wool has certain elasticity and plasticity, it can be fine-tuned according to the shape and size of the clamped object to ensure the tightness and stability of the clamping.

[0027] A five-finger column 13 is arranged on the top of the mounting frame 1 , and there are four five-finger columns 13 , each of which is located above each vertical mechanism.

[0028] By setting up the five-finger column 13, when the vertical mechanism uses the rotational force of the roller motor 8 to straighten the hanging woven sling and lift it upward to a vertical state, each five-finger column can accurately pass through the straightened woven strip to form a stable fixing point, effectively preventing the woven sling from falling again in subsequent operations. This instant and stable fixing mechanism greatly improves the continuity and efficiency of the production line.

[0029] Among them, the materials of the mounting frame 1, the moving frame 2, the fixed plate 1 3, the rotating rod 5, the sprocket 1 6, the chain 7, the fixed plate 2 9, the rotating shaft 10, the sprocket 2 11 and the L-shaped block 12 are all made of stainless acid-resistant steel.

[0030] By setting the stainless acid-resistant steel material, it is not only corrosion-resistant, but also has high strength and excellent mechanical properties. This enables the gripper structure to maintain structural integrity and stability when subjected to harsh working conditions such as heavy loads, vibrations and impacts. Its durability also ensures the reliability of the equipment during long-term operation, reducing failure rates and downtime.

[0031] The working principle and use process of this utility model:

[0032] The staff will first carefully arrange the ton bags to be processed to ensure that they are safely placed in the special working area of ​​the device. Then, the staff will start the motor 4. The rotation of the motor 4 is transmitted to the sprocket 1 6 through the rotating rod 5. The sprocket 1 6 serves as the starting point of the transmission chain and is tightly engaged with the chain 7 to smoothly transmit the power to the sprocket 2 11. With the start of the sprocket chain transmission system, the two roller motors 8 begin to move towards each other according to the preset specific motion path. The outer walls of the two roller motors 8 are covered with a layer of plastic fiber with a specific hardness and length. When these fibers come into contact with the woven strips, they can generate sufficient friction to gradually guide and straighten the originally disordered woven strips to a vertical state. With the coordinated action of the two roller motors 8, the ton bag woven strips are effectively arranged into an orderly arrangement. When the woven strips are straightened to the appropriate position, the five-finger column 13 on the upper part of the device responds quickly as part of the existing mechanism, and accurately extends out and penetrates the gaps naturally formed between the ton bag woven strips after being pulled up, so that it can firmly clamp the woven strips to prevent them from loosening or deformation. After the fixation is completed, the staff can further process or transport the fixed woven strips according to specific work needs, making the subsequent processing smoother and more efficient.
