Description

Technical Field

[0001] This application relates to the field of material shielding cart technology, and more particularly to a chain tensioning device for a material shielding cart. Background Technology

[0002] With the continuous development of modern tobacco processing technology, the storage requirements for materials such as tobacco shreds are becoming increasingly stringent. To ensure that the quality of materials in storage cabinets meets the requirements of the production process, it is necessary to strictly control the heat preservation, moisture retention, dust prevention, and prevention of cross-contamination of aromas within the storage cabinets. During the transportation and storage of materials, it is often necessary to cover them to maintain their cleanliness and integrity. Therefore, storage cabinets for storing tobacco shreds are equipped with chains and covering cloths for this purpose. The covering cloth is placed over the storage cabinet by the chains, and the chains are tensioned by a tensioning device. However, placing the tensioning device inside the storage cabinet occupies storage space and reduces the utilization rate of the storage cabinet. Utility Model Content

[0003] In view of this, this application proposes a chain tensioning device for a material shielding vehicle.

[0004] To address the issue of traditional tensioning mechanisms occupying space inside the material-covering vehicle, this utility model provides a solution comprising: a chain tensioning mechanism;

[0005] The chain tensioning mechanism is located on the outside of the material shielding vehicle;

[0006] The chain tensioning mechanism includes a tensioning fixed bracket, a tensioning sliding bracket, a tensioning adjusting bolt, a tensioning spring, and a rotary sprocket. The tensioning fixed bracket is fixed to the outside of the material shielding cart. The tensioning adjusting bolt passes through the tensioning spring and is rotatably mounted on the tensioning fixed bracket. Both ends of the tensioning spring abut against the tensioning adjusting bolt and the tensioning sliding bracket, respectively. The tensioning sliding bracket is connected to the rotary sprocket to adjust the position of the rotary sprocket. The rotary sprocket meshes with the chain of the material shielding cart to adjust the chain tension.

[0007] One possible implementation also includes: mounting brackets;

[0008] The mounting bracket is disposed outside the material covering vehicle, the rotary sprocket is disposed on the mounting bracket, and the rotation direction of the rotary sprocket is tangent to the chain drive direction of the material covering vehicle.

[0009] One possible implementation also includes: a sprocket adjusting shaft;

[0010] The sprocket adjustment shaft is slidably mounted on the mounting bracket, with rotating sprockets at both ends connected to the tensioning sliding bracket, thereby adjusting the position of the rotating sprockets on the mounting bracket.

[0011] In one possible implementation, the tensioning sliding bracket includes: an abutment portion and an adjustment portion;

[0012] The abutment part is a ring-shaped structure, sleeved on the tension adjusting bolt, and the diameter of the spring is smaller than the outer ring diameter of the abutment part and larger than the inner ring diameter of the abutment part;

[0013] The adjusting part is a plate-shaped structure, which is fixedly connected to the abutting part and the sprocket adjusting shaft respectively, and the plate surface of the adjusting part is perpendicular to the plate surface of the mounting bracket;

[0014] The plate surface direction of the adjusting part is perpendicular to the sliding direction of the abutting part, and the plate surface direction of the adjusting part is perpendicular to the moving direction of the sprocket adjusting shaft.

[0015] In one possible implementation, the tension spring is in a compressed state.

[0016] In one possible implementation, the axial length direction of the tension adjusting bolt is parallel to the axial length direction of the sprocket adjusting shaft.

[0017] One possible implementation also includes: a 204 bearing;

[0018] The sprocket adjusting shaft is connected to the rotary sprocket via the 204 bearing.

[0019] In one possible implementation, there are two chain tensioning mechanisms, both located in the middle of the frame of the material-covering vehicle, which respectively adjust the tension of the chains on both sides.

[0020] The beneficial effects of the chain tensioning device of the material shielding cart according to the embodiments of this application are as follows: By placing the chain tensioning mechanism on the outside of the material shielding cart, the chain tensioning mechanism does not need to occupy the chain installation position on the frame, thereby increasing the usable space of the frame and reducing the overall cost. Furthermore, by using a chain tensioning mechanism, the reciprocating chain can be tensioned, preventing the chain from loosening during use. Specifically, the tensioning fixing bracket is fixed to the external structure of the material shielding cart. The tension adjusting bolt passes through the tension spring and can be rotated and adjusted on the tension fixing bracket. Simultaneously, both ends of the tension spring abut against the tension adjusting bolt and the tension sliding bracket, respectively, allowing the tension spring to undergo elastic deformation under the action of the adjusting bolt, thereby providing a stable tension force to the chain. The tension sliding bracket is tightly connected to the rotating sprocket; by adjusting the position of the sliding bracket, the spatial position of the rotating sprocket can be adjusted, thereby achieving control of the chain tension of the material shielding cart.

[0031] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0032] like Figures 1-4 As shown, the chain tensioning device of the material shielding cart in this embodiment of the application includes: a chain tensioning mechanism 10, which is disposed outside the material shielding cart 20. The chain tensioning mechanism 10 includes a tension fixing bracket 100, a tension sliding bracket 400, a tension adjusting bolt 300, a tension spring 200, and a rotary sprocket 500. The tension fixing bracket 100 is fixed outside the material shielding cart 20. The tension adjusting bolt 300 passes through the tension spring 200 and is rotatably disposed on the tension fixing bracket 100. The two ends of the tension spring 200 abut against the tension adjusting bolt and the tension sliding bracket 400, respectively. The tension sliding bracket 400 is connected to the rotary sprocket 500 to adjust the position of the rotary sprocket 500. The rotary sprocket 500 meshes with the chain of the material shielding cart 20 to adjust the chain tension.

[0033] In this specific embodiment, by placing the chain tensioning mechanism 10 outside the shielding cart 20, the chain tensioning mechanism 10 does not need to occupy the chain mounting position on the frame, thereby increasing the usable space of the frame and reducing the overall cost. Furthermore, by using the chain tensioning mechanism 10, the reciprocating chain can be tensioned, preventing it from loosening during use. Specifically, the tension fixing bracket 100 is fixed to the external structure of the shielding cart 20. The tension adjusting bolt 300 passes through the tension spring 200 and can be rotated and adjusted on the tension fixing bracket 100. Simultaneously, both ends of the tension spring 200 abut against the tension adjusting bolt 300 and the tension sliding bracket 400, respectively, allowing the tension spring 200 to undergo elastic deformation under the action of the adjusting bolt, thus providing a stable tension force to the chain. The tension sliding bracket 400 is tightly connected to the rotary sprocket 500. By adjusting the position of the sliding bracket, the spatial position of the rotary sprocket 500 can be adjusted, thereby controlling the chain tension of the shielding cart 20.

[0034] In one specific embodiment, it further includes: a mounting bracket 700, which is disposed outside the sub-concealing cart 20, providing a more stable support platform for the rotary sprocket 500. The rotary sprocket 500 is disposed on the mounting bracket 700, and the rotation direction of the rotary sprocket 500 is tangent to the chain drive direction of the concealing cart 20. Its rotation direction is tangent to the chain drive direction of the concealing cart 20, thereby maximizing the energy transfer efficiency and ensuring that the rotary sprocket 500 can adjust the chain tension.

[0035] The mounting bracket 700 has its plate surface in the same plane as the reciprocating direction of the chain.

[0036] In one specific embodiment, it further includes: a sprocket adjusting shaft 600, which is slidably mounted on the mounting bracket 700, with its two ends connected to a rotary sprocket 500 and a tensioning sliding bracket 400, respectively. By adjusting the position of the rotary sprocket 500 on the mounting bracket 700, the position of the rotary sprocket 500 on the mounting bracket 700 can be easily changed, thereby achieving a wider range of control over the chain tension.

[0037] In one specific embodiment, the tension sliding bracket 400 includes an abutment portion 420 and an adjusting portion 410. The abutment portion 420 is an annular structure, sleeved on the tension adjusting bolt 300. The diameter of the spring is smaller than the outer diameter of the abutment portion 420 but larger than the inner diameter of the abutment portion 420. The adjusting portion 410 is a plate-like structure, fixedly connected to the abutment portion 420 and the sprocket adjusting shaft 600, respectively, and the plate surface of the adjusting portion 410 is perpendicular to the plate surface of the mounting bracket 700. The bolt heads of the abutment portion 420 and the tension adjusting bolt 300 are located at opposite ends of the tension spring 200, and can be pushed in opposite directions by the elastic force of the tension spring 200. The plate-like structure of the adjusting portion 410 is used to firmly fix it to the mounting bracket and to the sprocket adjusting shaft 600, so as to provide power for the sprocket adjusting shaft 600 and the rotating chain to move.

[0038] The direction of the plate surface of the adjusting part is perpendicular to the sliding direction of the abutment part 420, and the direction of the plate surface of the adjusting part is perpendicular to the moving direction of the sprocket adjusting shaft 600.

[0039] In one specific embodiment, the tension spring 200 is in a compressed state to provide continuous tension. Simultaneously, with the tension adjusting bolt 300 fixed, the tension spring 200 can only be pushed away from the bolt head towards the abutment portion 420 of the tension sliding bracket 400.

[0040] In one specific embodiment, the axial length direction of the tension adjusting bolt 300 is parallel to the axial length direction of the sprocket adjusting shaft 600. This facilitates adjusting the sliding direction of the sprocket adjusting shaft 600. Keeping the axial length direction of the tension adjusting bolt 300 parallel to the axial length direction of the sprocket adjusting shaft 600 helps simplify the adjustment process and improve adjustment efficiency.

[0041] In one specific embodiment, it also includes: a 204 bearing, the sprocket adjusting shaft 600 is connected to the rotary sprocket 500 through the 204 bearing, which reduces friction loss and improves the rotational flexibility and stability of the rotary sprocket 500.

[0042] In one specific embodiment, there are two chain tensioning mechanisms 10, both of which are located in the middle of the frame of the material shielding car 20, and adjust the tension of the chains on both sides respectively.

[0043] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
