Description

Technical Field

[0001] This utility model relates to the field of industrial automation equipment technology, and in particular to an alkali bag handling gripper for alkali solution preparation in a decoction system. Background Technology

[0002] In industrial decoction systems, the preparation of alkali solution is a crucial step, typically involving the feeding of bagged solid alkali into a dissolving tank. Currently, some factories still rely on manual labor for handling and feeding the alkali bags. This method is not only labor-intensive and inefficient, but more importantly, direct manual contact with alkali, which is usually highly corrosive and generates dust, poses serious safety hazards.

[0003] To address these issues, the industry has begun using robots in conjunction with end effectors to replace manual labor and automate the handling of alkali bags. However, existing automated handling grippers still have shortcomings in practical applications: First, when the robot drives the grippers at high speeds, starts, stops, or turns, the gripped alkali bags are prone to shaking due to inertia, generating significant impact forces through the rigidly connected grippers. This impact not only affects the positioning accuracy of the robot's end effector but may also damage the robot body and gripper structure over time, shortening the equipment's lifespan. Second, after the alkali bags are emptied by the bag-breaking device, some alkali material often adheres to and remains inside. Existing grippers typically lack the ability to process empty bags, and this residual material is discarded along with the empty bag, resulting in unnecessary raw material waste and increased production costs.

[0004] Therefore, this utility model proposes an alkali bag handling gripper for alkali solution preparation in a decoction system to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an alkali bag handling gripper for alkali solution preparation in a decoking system. It aims to improve the problems of existing alkali bag handling grippers for alkali solution preparation in decoking systems, such as large shaking and impact during handling due to rigid connection, low equipment reliability, and single function, which cannot handle material residue in the bag and thus waste raw materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A alkali bag handling gripper for alkali solution preparation in a decoction system includes: a connecting plate, a mounting plate, a drive cylinder, a drive shaft, and grippers driven by the drive shaft; as well as a buffer assembly and an exhaust assembly.

[0007] The buffer component is used to achieve an elastic connection between the connecting plate and the mounting plate.

[0008] Furthermore, the buffer assembly is disposed between the connecting plate and the mounting plate, and the exhaust assembly is mounted on the mounting plate in a combined manner.

[0009] Preferably, the buffer assembly includes a spring guide rod and a buffer spring fitted onto the outside of the spring guide rod.

[0010] Preferably, the buffer assembly further includes a guide shaft, which is arranged parallel to the spring guide rod and is used to guide and limit the buffer movement of the mounting plate.

[0011] Preferably, the buffer assembly further includes a buffer pad disposed at the end of the buffer spring, which serves to buffer the mounting plate and prevent the buffer spring from dislodging.

[0012] Preferably, the exhaust assembly includes an exhaust cylinder and an exhaust plate connected to the piston rod of the exhaust cylinder.

[0013] Preferably, the transport gripper further includes a support column connected between the connecting plate and the mounting plate for support and connection.

[0014] Preferably, the transport gripper further includes a fixing plate that connects the buffer assembly to the mounting plate or the connecting plate.

[0015] Preferably, the connecting plate is used to detachably mount the handling gripper to the robot body.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting a buffer component between the connecting plate and the mounting plate, the elastic deformation of the buffer component solves the problem in the prior art where the rigid connection of the handling gripper causes the alkali bag to shake and generate huge impact force during the handling process, resulting in easy damage to the equipment and unstable operation. It achieves the beneficial effects of effectively absorbing impact, ensuring a stable and reliable handling process, and extending the service life of the equipment.

[0017] 2. In this utility model, by adding an exhaust component to the mounting plate, the empty bag is squeezed by the exhaust plate after the alkali bag is broken, which solves the problem that a large amount of material remains in the bag after the alkali bag is poured out, causing raw material waste. It achieves the beneficial effects of squeezing out the residual material in the bag, improving the utilization rate of raw materials, and reducing production costs.

[0018] 3. In this utility model, by integrating the functions of gripping, buffering, and emptying after bag breaking into an automated gripper structure, the problems of high labor intensity, high safety risks, and low operating efficiency in the traditional manual handling and processing of alkali bags are solved, achieving the beneficial effect of automating the entire process of alkali bag processing and improving production safety and efficiency.

[0021] 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.

[0022] Example: Please refer to the appendix. Figure 1 -Appendix Figure 5 This utility model provides an alkali bag handling gripper for alkali solution preparation in a decoction system, which aims to solve the technical problems in the prior art where the handling device generates impact force due to shaking during movement, and where material residue exists after the alkali bag is broken.

[0023] The top of the alkali bag handling gripper for alkali solution preparation in the decoction system is provided with a connecting plate 2. The connecting plate 2 is used to detachably install the handling gripper to the robot body 1. Below the connecting plate 2, there is a mounting plate 9. The mounting plate 9 serves as the mounting base for the entire actuator and is used to support various functional components on it. The connecting plate 2 and the mounting plate 9 are connected by a buffer component 3 and a support column 5, thus forming the overall frame of the handling gripper.

[0024] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the overall frame of the transport gripper is not rigidly connected, but elastically connected through a buffer component 3, and functionally an exhaust component 8 is added.

[0025] Specifically, the buffer assembly 3 includes a spring guide rod 301, a buffer spring 302, a guide shaft 303, and a buffer pad 304. The spring guide rod 301 and the guide shaft 303 are both vertically arranged. Their upper ends are fixedly connected to the connecting plate 2 through the fixing plate 10, and their lower ends pass through the through hole on the mounting plate 9 and slide in cooperation with the mounting plate 9. The buffer spring 302 is fitted outside the spring guide rod 301 and is located between the connecting plate 2 and the mounting plate 9. The buffer pad 304 is disposed at the end of the buffer spring 302. Through this elastic and guided connection structure, the mounting plate 9 can perform controlled buffering movement relative to the connecting plate 2 under the guiding and limiting action of the guide shaft 303, thereby effectively absorbing the impact and vibration during the transportation process.

[0026] Meanwhile, an exhaust assembly 8 is fixedly installed on the lower surface of the mounting plate 9. The exhaust assembly 8 consists of an exhaust cylinder 801 and an exhaust plate 802. The cylinder body of the exhaust cylinder 801 is fixed on the mounting plate 9, and the end of its piston rod is fixedly connected to the exhaust plate 802. When the exhaust cylinder 801 is activated, it can drive the exhaust plate 802 to move downward, thereby realizing the function of squeezing and emptying the empty alkali bag.

[0027] Based on the above embodiments, the structure of the handling gripper can be further optimized. Specifically, the connecting plate 2 and the mounting plate 9 are connected by at least two support columns 5. The two ends of the support columns 5 are fixedly connected to the connecting plate 2 and the mounting plate 9 by bolts, thereby forming a rigid and stable support frame.

[0028] In order to realize the action of the gripper, a drive cylinder 4 is fixedly installed on the mounting plate 9. The output end of the drive cylinder 4 is connected to the drive shaft 6. The drive shaft 6 is rotatably mounted on the mounting plate 9, and the gripper 7 is fixedly connected to the drive shaft 6. The reciprocating motion of the drive cylinder 4 is converted into the opening and closing action of the gripper 7 through the rotation of the drive shaft 6.

[0029] As a further limitation of the buffer assembly 3, the transport gripper also includes a fixing plate 10, which is welded or bolted to the lower surface of the connecting plate 2. The upper ends of the spring guide rod 301 and the guide shaft 303 are both fixed to the fixing plate 10. The lower end of the spring guide rod 301 slides through the mounting plate 9. The buffer spring 302 is sleeved on the outer periphery of the spring guide rod 301 and is compressed and installed between the fixing plate 10 and the mounting plate 9. The guide shaft 303 is arranged parallel to the spring guide rod 301, and its lower end also slides through the mounting plate 9 to prevent the mounting plate 9 from rotating during the buffering process. A buffer pad 304 is also provided between the lower end of the buffer spring 302 and the mounting plate 9. The buffer pad 304 can be made of elastic materials such as rubber or polyurethane.

[0030] Working principle: When it is necessary to move alkali bags, the robot body 1 first starts and adjusts the handling gripper to the identified alkali bag position. Then, the drive cylinder 4 is started, which drives the drive shaft 6 to rotate. The rotation of the drive shaft 6 causes the gripper 7 to open, preparing to grab the alkali bag. Subsequently, the drive cylinder 4 retracts, causing the gripper 7 to close and firmly grasp the alkali bag. During the entire handling process, when the alkali bag shakes and generates impact force, the impact force is transmitted to the buffer spring 302 through the mounting plate 9. The buffer spring 302 is compressed and deformed under the guidance and limiting action of the spring guide rod 301 and the guide shaft 303, absorbing most of the impact energy. The buffer pad 304 further provides cushioning to the mounting plate 9 and prevents the spring from dislodging, ensuring that the handling gripper body will not be impacted or displaced due to shaking, thus improving the stability and safety of handling.

[0031] When the robot body 1 transports the alkali bag it has grabbed to the bag-breaking device and needs to release it, the drive cylinder 4 is started again, pushing the drive shaft 6 to rotate so that the gripper 7 opens and accurately puts the alkali bag down. After the alkali bag is broken and the material is poured out, the exhaust cylinder 801 is started. The exhaust cylinder 801 pushes the exhaust plate 802 downward to squeeze and empty the empty alkali bag, so as to maximize the recovery of the residual material in the bag and avoid waste.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
