[0006] According to one aspect of the utility model, an elastic opening and closing device for a box body flap is provided, which includes a mounting frame, a material box, a driving component, a flap, and an elastic opening and closing mechanism. The material box is rotatably arranged on the mounting frame. The driving component is arranged on the mounting frame, and its driving end is connected to the material box and is used to drive the material box to rotate relative to the mounting frame for tilting and discharging. The flap is rotatably connected to the material box and covers the discharge port of the material box. The flap is used to flip downward relative to the material box to open the discharge port on the material box when the material box is tilted for discharging. The elastic opening and closing mechanism is respectively connected to the free end of the flap and the material box and is used to apply a reset elastic force to the flap when the flap flips downward.

[0007] As a further improvement of the above technical solution:

[0008] Further, the elastic opening and closing mechanism includes a tension spring with the first end connected to the flap and an adjusting member arranged on the material box and connected to the second end of the tension spring for adjusting the elongation of the tension spring relative to the material box.

[0009] Further, the adjusting member includes a fixing plate fixedly arranged on the material box, an adjusting bolt movably penetrating through the fixing plate, an adjusting plate fixedly connected to the first end of the adjusting bolt and connected to the second end of the tension spring, and an adjusting nut threadedly connected to the second end of the adjusting bolt.

[0017] The present invention has the following beneficial effects:

[0018] The elastic opening and closing device for the box door of the present utility model installs a material box on the installation rack, stores materials through the material box. When it is necessary to tilt and unload the materials, the driving component drives the material box to rotate relative to the installation rack so that the material box is in a tilted state. At this time, the discharge port of the material box is located at the lower end of the material box, enabling the flap to rotate downward relative to the material box under the dual action of its own gravity and the gravity of the materials, thereby automatically opening the discharge port on the material box and discharging the materials. At the same time, during the process of the flap rotating downward and opening, a downward acting force will be generated on the elastic opening and closing mechanism, enabling the elastic opening and closing mechanism to apply a restoring elastic force to the flap. After the discharging is completed, the driving component drives the material box to rotate in the reverse direction relative to the installation rack so that the material box returns to its initial state. At this time, the flap is no longer affected by its own gravity and the gravity of the materials, and automatically closes the flap under the action of the elastic force of the elastic opening and closing mechanism; This solution realizes the automatic opening and closing of the flap on the material box through the coordinated cooperation of the material box, the driving component, and the elastic opening and closing mechanism. Compared with the prior art, the opening and closing process of the flap is simple and convenient, and no additional power source is required. In addition, the elastic closing of the flap is beneficial to ensuring smooth movement and no impact during the closing process of the flap, reducing the safety risk of components impacting and colliding with each other, and also avoiding the risk of the flap crushing the materials during the closing process. It has strong practicability and is suitable for wide promotion and application.

[0026] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0027] As Figures 1 - 3 shown, the elastic opening and closing device for the box flap of this embodiment includes an installation rack 10, a material box 20, a driving assembly 30, a flap 40, and an elastic opening and closing mechanism. The material box 20 is rotatably arranged on the installation rack 10. The driving assembly 30 is arranged on the installation rack 10 and its driving end is connected to the material box 20 and is used to drive the material box 20 to rotate relative to the installation rack 10 for tipping and discharging materials. The flap 40 is rotatably connected to the material box 20 and covers the discharge port of the material box 20. The flap 40 is used to flip downward relative to the material box 20 to open the discharge port on the material box 20 when the material box 20 tips and discharges materials. The elastic opening and closing mechanism is respectively connected to the free end of the flap 40 and the material box 20 and is used to apply a restoring elastic force to the flap 40 when the flap 40 flips downward.

[0028] As Figure 2 shown, it should be understood that in this embodiment, the material box 20 tips and discharges materials. Therefore, the discharge port on the material box 20 is opened at the lower end of the material box 20 in the tipping state to automatically discharge materials by using gravity.

[0029] As Figures 1 - 3As shown in the figure, specifically, for the elastic opening and closing device of the box body of the present utility model, a material box 20 is installed on the installation rack 10, and materials are stored in the material box 20. When tilting for discharging, the driving assembly 30 drives the material box 20 to rotate relative to the installation rack 10, so that the material box 20 is in a tilted state. At this time, the discharge port of the material box 20 is located at the lower end of the material box 20, enabling the flap 40 to rotate downward relative to the material box 20 under the dual action of its own gravity and the gravity of the materials, thereby automatically opening the discharge port on the material box 20, and discharging the materials. At the same time, during the process of the flap 40 rotating downward to open, a downward force will be generated on the elastic opening and closing mechanism, so that the elastic opening and closing mechanism exerts a restoring elastic force on the flap 40. After the discharging is completed, the driving assembly 30 drives the material box 20 to rotate in the opposite direction relative to the installation rack 10, so that the material box 20 returns to its initial state. At this time, the flap 40 is no longer affected by its own gravity and the gravity of the materials, and automatically closes the flap 40 under the action of the elastic force of the elastic opening and closing mechanism; through the coordinated cooperation of the material box 20, the driving assembly 30 and the elastic opening and closing mechanism, the automatic opening and closing of the flap 40 on the material box 20 is realized. Compared with the prior art, the opening and closing process of the flap 40 is simple and convenient, and no additional power source is required. In addition, the elastic closing of the flap 40 is beneficial to ensuring the smooth movement and no impact of the flap 40 during the closing process, reducing the safety risk of mutual impact and collision of components, and also avoiding the risk of crushing materials by the flap 40 during the closing process. It has strong practicability and is suitable for wide promotion and application.

[0030] As Figures 1 - 3 shown, in this embodiment, the elastic opening and closing mechanism includes a tension spring 51 with its first end connected to the flap 40 and an adjusting member disposed on the material box 20 and connected to the second end of the tension spring 51 for adjusting the elongation of the tension spring 51 relative to the material box 20. Specifically, when the material box 20 is tilted for discharging, under the dual action of the gravity of the flap 40 and the gravity of the materials, the flap 40 rotates downward to open the discharge port. At this time, the tension spring 51 is stretched synchronously, so that the tension spring 51 generates elastic deformation, and then the tension spring 51 exerts a restoring elastic force on the flap 40. And according to the discharging amount of the materials, the opening and closing angle of the flap 40 can be changed steplessly to improve the discharging efficiency. After the discharging is completed, the tension spring 51 pulls the flap 40 to close the discharge port; by adjusting the elongation of the tension spring 51 relative to the material box 20, the gravity required for the flap 40 to open is reduced or increased, so as to further adjust the opening and closing angle of the flap 40. The specific adjustment amount can be adaptively adjusted according to the discharging requirements.

[0031] As Figures 1 - 3As shown in the figure, in this embodiment, the adjusting member includes a fixing plate 52 fixedly disposed on the material box 20, an adjusting bolt 53 movably inserted through the fixing plate 52, an adjusting plate 54 fixedly connected to the first end of the adjusting bolt 53 and connected to the second end of the tension spring 51, and an adjusting nut 55 threadedly connected to the second end of the adjusting bolt 53. Specifically, the adjusting bolt 53 is installed through the fixing plate 52, then the adjusting plate 54 is connected through the adjusting bolt 53, then the adjusting plate 54 is connected to the second end of the tension spring 51, and finally the adjusting nut 55 is threadedly connected to the second end of the adjusting bolt 53 to complete the assembly of the adjusting member; during the assembly process, by rotating the adjusting nut 55, the adjusting nut 55 and the adjusting bolt 53 move relative to each other, and the gravity required when the valve 40 is opened can be reduced or increased. Optionally, the adjusting member further includes a limiting plate 56 fixedly disposed on the material box 20 for limiting and guiding the adjusting plate 54.

[0032] As Figure 3 shown in the figure, in this embodiment, a first hook connected to the first end of the tension spring 51 is arranged on the valve 40, and a second hook connected to the second end of the tension spring 51 is arranged on the adjusting plate 54, and the first hook and the second hook are arranged opposite to each other. Specifically, the first end and the second end of the tension spring 51 are respectively connected to the first hook and the second hook to complete the rapid assembly of the tension spring 51, and the assembly process is simple and the maintenance is convenient; that is, when the tension spring 51 has permanent elastic deformation or is torn and damaged, the tension spring 51 can be quickly replaced.

[0034] As Figure 2As shown in the figure, in this embodiment, the mounting frame 10 includes a horizontal support portion 11 arranged in the horizontal direction, an inclined connection portion 12 with its first end connected to the first end of the horizontal support portion 11 and its second end hinged to the material box 20, and an inclined mounting portion 13 connected to the second end of the horizontal support portion 11 and the second end of the inclined connection portion 12 respectively. The first mounting seat 31 is fixedly arranged on the inclined surface of the inclined mounting portion 13. Specifically, the mounting frame 10 supports the material box 20 from the bottom through the horizontal support portion 11, then hinges the material box 20 through the inclined connection portion 12, and then installs the first mounting seat 31 through the inclined mounting portion 13 to achieve reliable support for the material box 20. Optionally, the shape after the connection of the horizontal support portion 11 and the inclined connection portion 12 matches the outer wall shape of the material box 20 to improve the reliability after the assembly of the material box 20.
