Description

Technical Field

[0001] This utility model relates to an automatic unloading device for reducing the breakage rate of flexible materials, belonging to the field of explosion-proof material unloading technology. Background Technology

[0002] Explosion-proof materials are mainly used inside containers such as cans to prevent them from exploding due to external forces. In the production equipment for explosion-proof materials, semi-automatic cutting and mesh-making devices are widely used. However, the unloading process currently relies mainly on manual labor, resulting in low production efficiency, material folding during handling of accumulated materials, damage to the three-dimensional structure of the mesh, increased material breakage rate, reduced mechanical properties of the mesh, and decreased oil content in the can. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic unloading device that can replace manual labor to achieve stable feeding and unloading of flexible materials, automatically stack flexible materials flat, prevent flexible materials from curling, and reduce the breakage rate of flexible materials.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model includes: two parallel fixed supports, a steel strip tensioning shaft, a steel strip, and a winding roller. The steel strip tensioning shaft is located at the tail end between the two fixed supports, with both ends connected to the fixed supports via tension springs. The winding roller is located between the two fixed supports, with both ends slidably connected to the fixed supports, and is capable of rotational movement. One end of the steel strip is fixed to the steel strip tensioning shaft, and the other end is fixed to the winding roller. The steel strip can rotate and wind around the winding roller, or be released from the winding roller and stretched out as the winding roller slides.

[0006] The fixed bracket is a right-angled long strip bracket.

[0007] The two ends of the roll are slidably connected to the fixed brackets by setting a guide rail on the inner side of the two fixed brackets along the length of the brackets, and a slider is rotatably connected to each end of the roll, with each slider slidingly engaging with the corresponding guide rail.

[0008] A synchronous belt is installed inside each fixed bracket along the length of the bracket. The synchronous belt is a closed loop belt supported by rotating wheels at both ends. One of the rotating wheels of the synchronous belt on one side is connected to the shaft of a synchronous drive motor. The synchronous belt is located below the slider and is either frictionally engaged or fixedly connected to the lower part of the slider.

[0009] A synchronous gear is fixed to the inner side of the slider at both ends of the roll roller, and a synchronous rack is fixed to the lower side of the top plate of the fixed bracket along the length of the bracket. Each synchronous gear meshes with the corresponding synchronous rack.

[0010] The advantages of this utility model are:

[0011] (a) This utility model can realize the stable feeding and unloading of flexible materials, such as aluminum alloy mesh;

[0012] (b) This invention enables the automatic stacking of flexible materials;

[0013] (c) This utility model can achieve the effect of preventing flexible materials from rolling when laid flat;

[0014] (d) It can unload and stack flexible materials of different sizes in different areas, with a high degree of automation;

[0015] (e) Through the coiling action of the steel strip of this utility model, the flexible material can be unloaded without relative movement relative to the unloading area, ensuring that the flexible material is stacked flat.

[0016] In summary, this invention improves the production efficiency of the unloading process, reduces the breakage rate of the material mesh, and helps protect the three-dimensional structure and mechanical properties of the material mesh. Attached Figure Description

[0025] Referring to the accompanying drawings, this utility model includes: two parallel fixed supports 8, a steel strip tensioning shaft 1, a steel strip 6, and a winding roller 3. The fixed supports 8 are right-angled elongated supports. The steel strip tensioning shaft 1 is located at the tail end between the two fixed supports 8, and its two ends are connected to the fixed supports 8 through tension springs. A guide rail 7 is respectively arranged on the inner side of the two fixed supports along the length of the support. A slider 5 is rotatably connected to each end of the winding roller 3, and each slider 5 slides with the corresponding guide rail 7 to position the winding roller 3 between the two fixed supports 8. A synchronous belt 10 is arranged on the inner side of each fixed support 8 along the length of the support. The synchronous belt 10 is a closed loop belt with rotating wheels at both ends. The rotating wheels are supported by wheel frames fixed to the inner side of the fixed supports 8. One of the rotating wheels of the synchronous belt 10 on one side is connected to the shaft of a synchronous drive motor 9. The synchronous belt 10 is located below the slider 5, and the synchronous belt 10 is in frictional engagement or fixed connection with the lower part of the slider 5. A synchronous gear 4 is fixed inside the sliders 5 at both ends of the winding roller 3, and a synchronous rack 2 is fixed along the length of the bracket on the lower side of the top plate of the fixed bracket 8. Each synchronous gear 4 meshes with the corresponding synchronous rack 2. One end of the steel strip 6 is fixed to the steel strip tensioning shaft 1, and the other end is fixed to the winding roller 3. The steel strip 6 can be wound around the winding roller 3 as the winding roller 3 rotates, or released from the winding roller 3 and stretched out as the winding roller 3 slides.

[0026] During operation, the flexible raw material is fed onto the steel belt 6 of this invention through the previous process. The steel belt 6 serves to support the flexible material and ensure relative sliding with the flexible material during unloading. One end of the steel belt 6 is fixed to the steel belt tensioning shaft 1, and the other end is fixed to the winding roller 3. Synchronous gears 4 are fixed to both ends of the winding roller 3 and mesh with the synchronous rack 2. The winding roller 3 is slidably connected to the guide rail 7 via a slider 5 and can move linearly along the guide rail 7. The linear movement of the winding roller 3 is driven by the synchronous drive motor 9 and the synchronous belt 10, and is also driven to rotate by the synchronous gear 4 and the synchronous rack 2. The steel belt 6 rotates with the winding roller 3 and is wound onto the feeding roller 3.

[0027] When this utility model is in the extended state ( Figure 6 At this point, the material is being received. The flexible material is fed into the device from the previous process and is supported by the steel belt 6.

[0028] When this utility model is in the retracted state ( Figure 7 At this point, the steel strip 6 is in the unloading position. Driven by the winding roller 3, it is completely rewound and insufficient to support the flexible material. The flexible material falls to the lower stacked position. At this time, the winding roller reverses the above action and returns to the extended state. Figure 6 This marks the start of one work cycle.

[0029] As the coiling roller 3 drives the steel strip 6 to move in a straight line along the horizontal direction, its coiling action on the steel strip 6 gradually reduces the lower support of the flexible material placed on the steel strip 6. Furthermore, during the process of reducing the support, there is no relative displacement between the steel strip 6 and the contact part of the flexible material, which can ensure that there is no relative displacement between the flexible material and the unloading position.

[0030] The steel strip tensioning shaft 1 is connected to the fixed bracket 8 by a spring. During the process of the steel strip 6 being fully wound on the winding roller 3 and the steel strip 6 being fully unfolded to support the flexible material, the steel strip tensioning shaft 1 is used to tension the steel strip 6 in real time to ensure that the steel strip has a certain rigidity so as to provide sufficient support for the flexible material above it.

[0031] Unloading process: The synchronous drive motor 9 drives the synchronous belt 10 to move, and the synchronous belt 10 drives the slider 5 to move linearly along the guide rail 7. The winding roller 3 located on the slider 5 moves both linearly and rotaryly under the meshing action of the synchronous gear 4 and the synchronous rack 2. At this time, the steel strip 6 located at one end of the winding roller 3 begins to curl as the winding roller 3 rotates. As the synchronous belt 10 continues to move, the steel strip 6 retracts until the unloading process is completed. Similarly, after the unloading is completed, the above process is repeated to return to the initial receiving state.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
