Description

Technical Field

[0001] This utility model relates to the field of tooling vehicle technology, specifically a sealing device for a dustproof tooling vehicle used in foam production. Background Technology

[0002] In the foaming production process, tooling carts bear the heavy responsibility of material handling and storage. Their performance directly affects production efficiency. Because foamed products have strict requirements for environmental cleanliness, dust prevention is an essential function of tooling carts. At the same time, good shock absorption performance is also crucial to ensuring the integrity of materials. In addition, convenient operation procedures and flexible space layout are also key to improving production efficiency and adapting to the handling of various materials.

[0003] However, existing dustproof tooling for foam production has many problems. In terms of operation, the opening method is complicated, and the multiple latches or complex mechanical structure make it time-consuming and laborious to open the installation door, which seriously slows down the loading and unloading of items and hinders the smooth progress of the production process. In terms of space utilization, the internal layout is fixed, and the height of the placement plate cannot be flexibly adjusted according to the size and weight of the materials, which not only wastes space but also increases the risk of items tipping over and being damaged. The protective performance is also poor. The sealing between the installation door and the outer shell is rudimentary and cannot resist dust. Moreover, there is a lack of shock absorption measures, and vibration can easily damage the internal structure of the materials.

[0004] To address the aforementioned issues, we propose a sealing device for a dustproof tooling vehicle used in foam production. Utility Model Content

[0029] Structural Description:

[0030] 1. Base plate: The base plate is the basic load-bearing structure of the dustproof tooling cart in foam production, providing stable support for the entire device. It is the reference platform for the installation of other components. All components of the tooling cart are directly or indirectly connected to the base plate to ensure the overall stability of the device.

[0031] 2. Casters: Casters are installed at the bottom of the base plate and have the characteristic of flexible rotation, which allows the tooling cart to move freely in different directions. With casters, the tooling cart can easily change the direction of travel in complex environments such as production workshops to meet the diverse needs of material handling.

[0032] 3. Push rod: The push rod is installed at the corresponding two ends on the upper surface of the housing. It is the operating component for the operator to push the tooling cart. The operator applies pushing force by holding the push rod, so that the tooling cart can move in the predetermined direction, which facilitates the transfer of materials between different areas.

[0033] 4. Outer shell: The outer shell is the main structure of the tooling vehicle, used to house and protect the items placed inside. It provides a relatively independent space for the items, avoiding interference from external factors. It also serves as the mounting carrier for other components such as mounting doors and fixing blocks.

[0034] 5. Installation door: The installation door is installed at one end of the outer shell via hinges. It is the passage for entering and exiting the internal space of the outer shell. It can be opened and closed. When opened, it is convenient to put or take out items into the outer shell. When closed, it works with the outer shell to form a closed space, which serves to protect and prevent dust.

[0035] 6. Sealing gasket: The sealing gasket is installed inside the groove set at the connection between the mounting door and the outer shell. Its function is to enhance the sealing between the mounting door and the outer shell. When the mounting door is closed, the sealing gasket is squeezed and deformed to fill the gap between the two, effectively preventing external dust and other impurities from entering the interior of the outer shell.

[0036] 7. Buffer spring: The buffer spring is fixedly installed on the surface of the square groove at the bottom of the inner shell. Its upper end is fixedly connected to the placement base plate. When the tooling car moves and encounters vibration, the buffer spring can undergo elastic deformation to absorb and disperse the vibration energy, thereby reducing the impact on the items placed on the placement base plate and playing a buffer protection role.

[0037] 8. Placement base plate: The placement base plate is located inside the outer shell and is connected to the bottom of the outer shell through a buffer spring. It is a platform for placing larger items, providing a stable surface for the items. At the same time, the buffer spring helps to cushion the items and ensure their stability during transportation.

[0038] 9. Fixing block: The fixing block is fixedly installed on the inner wall of both ends of the housing. Its main function is to provide support and guidance for the adjusting rod. The fixing block is provided with specific holes or grooves so that the adjusting rod can slide in them, ensuring the stability and accuracy of the movement of the adjusting rod.

[0039] 10. Adjusting rod: The adjusting rod is installed at both ends of the fixed block. Its upper end penetrates the surface of the fixed block and is equipped with a fixing cover for limiting the position. The adjusting rod can slide up and down inside the fixed block to adjust the height of the placement board according to the weight and volume of the items placed on the placement board to meet the placement needs of different items.

[0040] 11. Adjusting spring: The adjusting spring is installed on the surface of the adjusting rod at the center of the fixed cover and the fixed block. It can produce elastic deformation according to the weight of the item. When the item is placed on the placement plate, the adjusting spring adjusts the height of the placement plate by extension and retraction, so as to achieve flexible adjustment of the placement space inside the tooling car.

[0041] 12. Placement plate: The placement plate is a component used to place small items. Its lower end is connected to the adjusting rod. Through the coordinated action of the adjusting rod and the adjusting spring, the placement plate can automatically adjust its height according to the weight and volume of the items, making full use of the internal space of the tooling car, while ensuring the stability of the items.

[0042] 13. Movable lever: The movable lever is located on the side of the housing and is the part operated by the operator. Pulling the movable lever can drive the connected lever to move, thereby controlling the position of the triangular plate and achieving the purpose of opening or closing the installation door limit.

[0043] 14. Pull rod: One end of the pull rod is fixedly connected to the inner end of the movable rod, and the other end is connected to the triangle plate. When the movable rod is pulled, the pull rod moves accordingly, transmitting the tension of the movable rod to the triangle plate, causing the triangle plate to produce a corresponding displacement.

[0044] 15. Return Spring: The return spring is sleeved on the surface of the pull rod. One end of the spring is fixedly connected to the triangular plate, and the other end is fixedly installed inside the limiting groove. When an external force pulls the movable rod to move the triangular plate, the return spring is compressed. When the external force disappears, the return spring pushes the triangular plate back to its initial position through its own elastic restoring force, thereby achieving the limiting and fixing of the installed door.

[0045] 16. Limiting groove: The limiting groove is set on the inner wall of the housing corresponding to the position of the return spring. It provides a limited space for the movement of the return spring and the triangular plate, ensuring that the return spring and the triangular plate move within the specified range and ensuring the normal operation of the limiting component;

[0046] 17. Triangle plate: The triangle plate is connected to the pull rod. Its shape and size match the triangular groove set on one side of the installation door. When the installation door is closed, the triangle plate is locked inside the triangular groove under the action of the return spring, so as to limit and fix the installation door and prevent the installation door from opening accidentally during the movement of the tooling trolley.

[0047] 18. Triangular groove: The triangular groove is set on one side of the door and is a structure that cooperates with the triangular plate. When the triangular plate is inserted into the triangular groove, the two fit tightly together to form a stable connection, ensuring the stability of the door when it is closed.

[0048] Instructions for use

[0049] Working principle: Casters 2 are installed at the lower end of the base plate 1, and the outer shell 4 is installed at the upper end of the base plate 1. The tooling cart is moved by pushing the push rod 3. Manually pulling the movable rod 13 moves the pull rod 14, causing the triangular plate 17 connected to the other end of the pull rod 14 to disengage from the triangular groove 18. The return spring 15 gradually compresses during the movement of the pull rod 14. When the triangular plate 17 is completely disengaged from the triangular groove 18, the mounting door 5 can be opened, revealing the internal space of the outer shell 4. After the mounting door 5 is opened, the movable rod 13 is released, and larger items are placed on the placement base plate 8 inside the outer shell 4. The placement base plate 8 is connected to the bottom of the outer shell 4 via a buffer spring 7. To absorb vibrations to a certain extent when pushing the tooling cart and protect the items from damage, small items are placed on the placement plate 12. The height of the placement plate 12 is automatically adjusted according to the weight and volume of the items by adjusting the spring 11 and the adjusting rod 10. The fixed cover at the upper end of the adjusting rod 10 prevents the adjusting rod 10 from sliding out of the range of the fixed block 9. After placement, the installation door 5 is closed. One end of the installation door 5 pushes the triangular plate 17 outward. After moving to a certain position, the pushing force disappears, and the return spring 15 pushes the triangular plate 17 inward. The triangular plate 17 is locked inside the triangular groove 18 to fix the installation door 5. The inside of the outer casing 4 can be observed through the viewing window.
