Technical Field
[0001] This utility model relates to the field of material conveying technology, specifically to a glove box feeding system that enables the dry transfer of materials. Background Technology
[0002] A glove box is a sealed operating device that provides a high-purity inert gas environment. It is widely used in fields with extremely strict requirements for water and oxygen content, such as lithium battery materials, pharmaceuticals, fine chemicals, semiconductors, and nuclear industries. Operators handle the materials inside the box using sealed gloves installed on the box, achieving "separation of personnel and materials." In the aforementioned industries, many raw materials or intermediates are often stored and transported in the form of ton bags. A ton bag is a large, flexible packaging container, usually made of materials such as polypropylene, and has the characteristics of large capacity, low cost, and convenient loading and unloading. Currently, the common method of feeding ton bags into glove boxes mostly relies on manual labor or simple mechanical assistance. Workers use overhead cranes or gantry cranes to lift the ton bags to the top of the glove box's inlet, and then the operator manually guides the ton bags to fall and attempts to align and seal their discharge port with the glove box's inlet flange.
[0003] Currently, when hoisting ton bags, due to their flexible nature, they are prone to swaying during transport, making it difficult to accurately align them with the relatively narrow feed inlet of the glove box. Furthermore, the impact of the falling ton bag during descent and positioning can damage the glove box's feeding device. After positioning, during unloading, the ton bag is prone to swaying or drifting due to material flow and changes in its shape, which can damage existing seals and potentially cause it to tip over, threatening the safety of equipment and operators. Moreover, the feed inlet of existing glove boxes is often exposed after feeding, requiring manual intervention for covering, which is not only cumbersome and inefficient but also prone to external contaminant intrusion due to forgetting or inadequate sealing, seriously threatening the stability of the high-purity process environment inside the glove box. Therefore, those skilled in the art provide a glove box feeding system that enables material drying and transfer to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to provide a glove box feeding system that enables material drying and transfer, thereby solving the problems mentioned in the background section of the prior art.
[0005] This utility model provides the following technical solution: a glove box feeding system for realizing material drying and transfer, including a mounting frame for support, a glove box body for separating people and materials fixedly installed on the lower part of the inner wall of the mounting frame, a transfer component for hoisting ton bags installed on the top of the inner wall of the mounting frame, a clamping component for fixing ton bags installed in the middle of the mounting frame, a buffer component for supporting the bottom of the ton bags installed on the lower part of the mounting frame, a protective component for shielding the feeding end of the glove box body installed on one side of the buffer component, and multiple pads fixedly connected to the lower end of the mounting frame.
[0006] As a preferred embodiment of the above technical solution, the transfer assembly includes a guide rail, which is fixedly connected to the top of the inner wall of the mounting frame. An electric hoist is installed on the outside of the guide rail, and a ton bag lifting frame is installed at the lower end of the electric hoist. Automatic locking hooks are installed at the four corners of the ton bag lifting frame.
[0007] As a preferred embodiment of the above technical solution, the clamping assembly includes a support frame, and two support frames are provided, which are arranged symmetrically. The two support frames are respectively fixedly connected to the lower sides of the mounting frame. An electric push rod is fixedly installed on the upper end of each of the two support frames, and a clamping rod is fixedly connected to the output end of each of the two electric push rods. The two clamping rods are arranged symmetrically.
[0008] As a preferred embodiment of the above technical solution, the buffer assembly includes springs and dampers, and multiple springs and dampers are provided. Multiple springs and multiple dampers are fixedly connected to the lower part of the mounting frame. Multiple dampers are respectively sleeved inside multiple springs. The upper ends of multiple springs and multiple dampers are fixedly connected to the buffer frame.
[0009] As a preferred embodiment of the above technical solution, the protective component includes a guide plate, a first rack, and a rotating rod. The guide plate is fixedly connected to one side of the mounting frame, the first rack is fixedly connected to the lower side of the buffer frame, and the rotating rod is rotatably connected to the lower part of the inner wall of the mounting frame. A small gear and a large gear are fixedly sleeved on the outside of the rotating rod, and the small gear and the first rack mesh with each other.
[0010] As a preferred embodiment of the above technical solution, a guide rod is slidably sleeved on the lower part of the guide plate, a protective cover is fixedly connected to the lower end of the guide rod, and a second rack is fixedly connected to the middle of the lower end of the protective cover, with the second rack meshing with the large gear.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This device automatically grabs, lifts, and precisely positions ton bags through a transfer component. Before and after the ton bag material falls to the designated feeding position, a buffer component effectively supports the bottom of the ton bag and mitigates the impact and vibration during its fall, eliminating swaying and drifting during feeding. This ensures the reliability and airtightness of the dynamic seal between the ton bag discharge port and the glove box inlet. After the ton bag descends to the feeding station, the clamping component horizontally clamps the ton bag from both sides, eliminating swaying and drifting during feeding. This further ensures the reliability and airtightness of the dynamic seal between the discharge port and the glove box inlet. At the same time, the automatically opening and closing protective component effectively prevents dust and debris from entering the glove box, ensuring the purity of the inert gas environment inside the glove box during use.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0015] Please see 1- Figure 6As shown, this utility model provides a technical solution: a glove box feeding system that can realize material drying and transfer, including a mounting frame 1 for support, a glove box body 2 for separating people and materials fixedly installed on the lower part of the inner wall of the mounting frame 1, a transfer component 3 for hoisting ton bags installed on the top of the inner wall of the mounting frame 1, a clamping component 4 for fixing ton bags installed in the middle of the mounting frame 1, a buffer component 5 for supporting the bottom of the ton bags installed on the lower part of the mounting frame 1, a protective component 6 for shielding the feeding end of the glove box body 2 installed on one side of the buffer component 5, and multiple pads 7 fixedly connected to the lower end of the mounting frame 1.
[0016] Furthermore, the mounting frame 1 provides a stable and rigid foundation for the entire device, ensuring precise integration of all components and long-term reliable operation. The glove box body 2, fixedly installed at the lower part of the mounting frame 1, is the core for achieving separation of personnel and materials and closed operation, directly ensuring the safety and dust-free operation of the high-purity material transfer process. The transfer component 3 set at the top of the mounting frame 1 realizes automatic hoisting and precise positioning of the ton bag, greatly improving feeding efficiency and reducing manual intervention. The clamping component 4 in the middle provides rigid clamping from both sides after the ton bag is in place, effectively suppressing the shaking and drifting of the ton bag during feeding. The buffer component 5 installed at the lower part effectively supports the ton bag through elastic lifting. The design mitigates the impact and vibration of the ton bag during its descent, ensuring a smooth and aligned connection between the ton bag and the inlet of the glove box body 2. This enables efficient, stable, and sealed feeding of the ton bag material within the glove box body 2 environment. Furthermore, the protective cover 607 moves away synchronously when the ton bag falls and automatically resets to cover the inlet after feeding, eliminating the risk of exposure of the inlet of the glove box body 2 during non-feeding periods. The entire process requires no manual intervention, preventing the possibility of external contaminants entering the glove box body 2. The feet 7 provide stable support for the entire mounting frame 1, and multiple mounting holes on the feet 7, combined with anchor bolts, allow the mounting frame 1 to be stably fixed in the designated position.
[0017] It should be noted that the glove box body 2 is existing technology, including a sealed main box, an observation window, built-in operating gloves, a gas purification and circulation system for maintaining a pure atmosphere inside the box, and a pressure control system for controlling the internal pressure. By creating a sealed space physically isolated from the external environment, the operator can handle the materials inside the box through the gloves on the box. At the same time, the purification system continuously removes impurities such as water and oxygen from the box and maintains a certain positive or negative pressure, thereby ensuring that the materials are always in the required high-purity inert gas environment or non-toxic negative pressure environment, achieving safe and pollution-free operation with separation of personnel and materials. This will not be elaborated further here.
[0018] As one implementation method in this embodiment, please refer to Figures 1-3As shown, the transfer component 3 includes a guide rail 301, which is fixedly connected to the top of the inner wall of the mounting frame 1. An electric hoist 302 is installed on the outside of the guide rail 301. A ton bag lifting frame 303 is installed at the lower end of the electric hoist 302. Automatic locking hooks 304 are installed at the four corners of the ton bag lifting frame 303.
[0019] Furthermore, the guide rail 301 provides a directional movement path for the electric hoist 302, enabling it to drive the ton bag lifting frame 303 and the automatic locking hook 304 to achieve automatic grabbing, lifting and horizontal transfer of the ton bag. This achieves precise and automated positioning of the ton bag from the preparation station to the glove box feeding port, replacing the inefficient and unsafe manual hoisting, significantly improving feeding efficiency, and ensuring the controllability of the operation process and the separation of personnel and materials.
[0020] It should be noted that the electric hoist 302 is existing technology, including a drive motor, a reduction mechanism, a drum device, a wire rope, and a braking system. The motor provides power, and the torque is increased by the reducer to drive the drum to rotate, thereby winding and unwinding the wire rope to achieve vertical lifting or lowering of heavy objects. The integrated brake ensures that the load can be safely suspended, providing the stable lifting force and controllable movement function required for ton bag lifting. The ton bag lifting frame 303 is hung on the hook at the lower end of the wire rope. The automatic locking hook 304 includes the hook body, a movable safety locking tongue, and a torsion spring that provides a restoring force. When the hook is under load, the locking tongue automatically closes under the elastic force of the torsion spring, forming a locking mechanism to prevent the sling from coming off. Thus, the ton bag sling can be automatically and safely locked without manual intervention, effectively avoiding the safety risks caused by hook disengagement during lifting.
[0021] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 As shown, the clamping assembly 4 includes a support frame 401. There are two support frames 401, which are arranged symmetrically. The two support frames 401 are fixedly connected to the lower sides of the mounting frame 1 respectively. An electric push rod 402 is fixedly installed on the upper end of each of the two support frames 401. A clamping rod 403 is fixedly connected to the output end of each of the two electric push rods 402. The two clamping rods 403 are arranged symmetrically.
[0022] Furthermore, a stable foundation is provided by two symmetrically fixed support frames 401 on the mounting frame 1. The electric push rods 402 installed on the support frames 401 can synchronously drive the clamping rods 403 on both sides to make horizontal linear movements. When the ton bag is in place, the electric push rods 402 extend and push the clamping rods 403 to apply a balanced clamping force to the ton bag body from both sides, thereby effectively eliminating the shaking and drifting of the ton bag during the feeding process, ensuring the reliability and stability of the dynamic seal between the ton bag discharge port and the glove box inlet, and realizing fully enclosed and dust-free feeding.
[0023] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 and Figure 5 As shown, the buffer assembly 5 includes springs 501 and dampers 502. Multiple springs 501 and multiple dampers 502 are provided. Multiple springs 501 and multiple dampers 502 are fixedly connected to the lower part of the mounting frame 1. Multiple dampers 502 are respectively sleeved inside multiple springs 501. The upper ends of multiple springs 501 and multiple dampers 502 are fixedly connected to a buffer frame 503.
[0024] Furthermore, when the ton bag falls, the impact force acts on the buffer frame 503. The spring 501 absorbs most of the impact energy through deformation, while the damper 502 quickly suppresses the reciprocating vibration of the spring 501. The soft rubber pad at the upper end of the buffer frame 503 further plays a role in buffering and anti-slip, significantly alleviating the impact and vibration when the ton bag falls, ensuring that the ton bag is placed stably and centered at the feeding position, providing a stable foundation for subsequent clamping and sealing operations, while protecting the equipment structure from impact damage. When the buffer frame 503 descends to its lowest point, the upper surface of the buffer frame 503 is higher than the glove box body 2, so that the ton bag is located above the glove box body 2 and does not contact the glove box body 2, thereby ensuring normal feeding.
[0025] It should be noted that after the electric push rod 402 resets, the two clamping rods 403 and the upper end of the buffer frame 503 are misaligned. Specifically, when the electric push rod 402 drives the two clamping rods 403 to move away from each other to their farthest point, the two clamping rods 403 are located on both sides below the buffer frame 503. That is, when the ton bag falls, the ton bag will pass between the two clamping rods 403 and then contact the upper end of the buffer frame 503. When the buffer frame 503 descends to its lowest point, the electric push rod 402 drives the clamping rods 403 to extend, thereby clamping the ton bag.
[0026] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the protective component 6 includes a guide plate 601, a first rack 602, and a rotating rod 603. The guide plate 601 is fixedly connected to one side of the mounting frame 1, the first rack 602 is fixedly connected to the lower side of the buffer frame 503, and the rotating rod 603 is rotatably connected to the lower part of the inner wall of the mounting frame 1. A small gear 604 and a large gear 605 are fixedly sleeved on the outside of the rotating rod 603, and the small gear 604 and the first rack 602 mesh with each other. A guide rod 606 is slidably sleeved at the lower part of the guide plate 601. A protective cover 607 is fixedly connected to the lower end of the guide rod 606. A second rack 608 is fixedly connected to the middle of the lower end of the protective cover 607. The second rack 608 and the large gear 605 mesh with each other.
[0027] Furthermore, when the ton bag descends and presses against the buffer frame 503, the buffer frame 503 moves downward, causing the first rack 602 fixed to its side to move downward simultaneously. The first rack 602 meshes with the pinion 604, driving the pinion 604 to rotate, which in turn drives the large gear 605 coaxially fixed on the rotating rod 603 to rotate. The large gear 605 meshes with the second rack 608, which is fixed to the protective cover 607. Therefore, the rotation of the large gear 605 will push the second rack 608 to slide, and the guide rod 606 slides within the guide plate 601, causing the protective cover 607 to move away from the feed end of the glove box body 2, making room for the docking of the ton bag with the feed inlet of the glove box body 2. After the ton bag is connected to the feed inlet of the glove box body 2, unloading is performed. At this time, the buffer frame 503 is still in a descending state due to the weight of the ton bag, and the protective cover 607 remains open. Due to the physical obstruction at the connection between the ton bag and the feed inlet of the glove box body 2, the protective cover 607 cannot be reset in advance. After unloading, the weight of the ton bag is reduced, and the buffer frame 503 begins to rise under the action of the spring 501 and the damper 502. However, at this time, the protective cover 607 still cannot move due to the connection of the ton bag. When the operator disconnects the ton bag from the feed inlet of the glove box body 2 and lifts the ton bag by the electric hoist 302, the buffer frame 503 is fully reset and rises. The first rack 602 rises accordingly. Through the reverse transmission of the small gear 604 and the large gear 605, the second rack 608 is driven to slide and reset the protective cover 607, which then re-covers the feed end of the glove box body 2. This effectively prevents dust and debris from entering the glove box body 2 and ensures the purity of the inert gas environment inside the glove box body 2 during use. At the same time, no additional power is required throughout the process, and the structure is simple and reliable.
[0028] Working principle: By operating the electric hoist 302 above the ton bag, the sling of the ton bag is hung in the automatic locking hook 304 of the ton bag frame 303. Then, the electric hoist 302 lifts the ton bag to a safe height. Then, the electric hoist 302 moves horizontally along the top guide rail 301, accurately transferring the ton bag to the top of the glove box body 2. Then, the electric hoist 302 drives the ton bag to slowly descend vertically. The bottom of the ton bag first contacts the buffer frame 503 of the buffer assembly 5. The soft rubber pad at the top of the buffer frame 503 plays a role in anti-slip and initial cushioning. The weight of the ton bag forces the buffer frame 503 to press down. Multiple springs 501 and dampers 502 under the ton bag start to work together to effectively absorb the energy when the ton bag descends, suppress vibration, and ensure that the ton bag is stable and stationary at the predetermined feeding position without rebound. When the ton bag descends and presses against the buffer frame 503, the buffer frame 503 moves downward, causing the first rack 602 fixed to its side to move downward synchronously. The first rack 602 meshes with the pinion 604, driving the pinion 604 to rotate, which in turn drives the large gear 605 coaxially fixed on the rotating rod 603 to rotate. The large gear 605 meshes with the second rack 608, which is fixed to the protective cover 607. Therefore, the rotation of the large gear 605 will push the second rack 608 to slide. The guide rod 606 slides in the guide plate 601, causing the protective cover 607 to move away from the feed end of the glove box body 2, making room for the docking of the ton bag with the feed inlet of the glove box body 2. After the ton bag is connected to the feed inlet of the glove box body 2, unloading is performed. At this time, the buffer frame 503 is still in a descending state due to the weight of the ton bag, and the protective cover 607 remains open. The physical obstruction at the connection between the ton bag and the feed inlet of the glove box body 2 prevents the protective cover 607 from resetting in advance. After unloading, the weight of the ton bag decreases, and the buffer frame 503 begins to rise under the action of the spring 501 and the damper 502. However, the protective cover 607 is still unable to move due to the connection of the ton bag. When the operator disconnects the ton bag from the feed inlet of the glove box body 2 and lifts the ton bag using the electric hoist 302, the buffer frame 503 fully resets and rises. The first rack 602 rises accordingly. Through the reverse transmission of the small gear 604 and the large gear 605, the second rack 608 is driven to slide and reset the protective cover 607, which re-blocks the feed end of the glove box body 2. This effectively prevents dust and debris from entering the glove box body 2, ensuring the purity of the inert gas environment inside the glove box body 2 during use. At the same time, no additional power is required throughout the process, making the structure simple and reliable. After the ton bag is stably placed on the buffer frame 503, the two electric push rods 402 extend synchronously, and the clamping rods 403 on both sides move forward horizontally to firmly clamp the ton bag body from both sides, eliminating any shaking or drifting of the ton bag during the feeding process. Then, the ton bag discharge port is connected to the feed port of the glove box body 2 for feeding. After the material in the ton bag is discharged, the discharge port is closed, the electric push rods 402 of the clamping component 4 are retracted, the clamping rods 403 release the ton bag, and the electric hoist 302 of the transfer component 3 lifts the empty ton bag, causing it to detach from the buffer frame 503. Then, it is transferred to the waste station along the guide rail 301, and the components are reset to the initial state, waiting for the next work cycle.
[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
