Description

Technical Field

[0001] This application relates to the field of material transport and shielding equipment technology, and in particular to a novel hinged 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 essential 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. Traditional covering methods mostly employ manual covering or fixed covering structures. These methods are not only inefficient but also difficult to adapt to materials of different sizes and shapes, and are also inconvenient to operate and maintain. Therefore, developing an automated, efficient, and adaptable covering device is particularly important. Conventional technology uses an "N"-shaped chain to lay the material; however, the chain itself has weight and can damage the sprockets on which it is mounted. Summary of the Invention

[0003] In view of this, this application proposes a novel hinged material shielding cart.

[0004] According to one aspect of this application, a novel hinged material covering vehicle is provided, comprising: a frame, a storage cabinet, a chain circulation traction system, and a material covering cloth;

[0005] The frame is a hollow frame structure;

[0006] The storage cabinet is mounted on the vehicle frame and located inside the vehicle frame;

[0007] The chain circulation traction system is located on the top of the vehicle frame and can drive the cover cloth to be laid from one end of the top of the storage tank to the other end of the storage tank;

[0008] The chain circulation traction system includes: running guide rails, transition sprockets, circulation chains, and a motor. Two running guide rails are arranged parallel to each other on the top sides of the frame along the length direction. Multiple transition sprockets are arranged on both sides of the frame in the width direction and sequentially along the height direction. The circulation chain is mounted on the transition sprockets and the running guide rails and can slide on the running track. The cover cloth is laid on the circulation chains on both sides. The motor drives the circulation chain to move from one end of the running track to the other end, controlling the cover cloth to be spread out or retracted.

[0009] In one possible implementation, each of the circulating chains is also arranged in a "Z" shape between the transition sprockets.

[0010] In one possible implementation, two adjacent transition sprockets are spaced apart by a predetermined distance in the height direction.

[0011] One possible implementation also includes: a support rod;

[0012] The two ends of the support rod are respectively fixed to the circulating chains located on both sides.

[0013] In one possible implementation, the support rod is a rod-shaped structure, and there are multiple support rods spaced apart along the length direction of the circulating chain.

[0014] In one possible implementation, sprockets are provided at both ends of the running track in the track direction;

[0015] The circulating chain wraps around the sprocket, causing the tarpaulin to slide at both ends of the running track in the direction of the track.

[0016] In one possible implementation, the covering fabric is made of pure cotton material, and the surface of the covering fabric is coated with PE adhesive.

[0017] In one possible implementation, the running track is located inside the chassis.

[0018] One possible implementation also includes: a shell;

[0019] The shell is a hollow structure with an opening at the bottom, and its length has a preset distance, while its width is equal to the width of the vehicle frame.

[0020] The housing covers the exterior of the plurality of transition sprockets and the motor.

[0021] In one possible implementation, the transition sprocket is rotatably mounted on the inner wall of the housing.

[0022] The beneficial effects of the novel hinge structure of the material-covering cart in this application embodiment are as follows: The circulating chain, arranged in a "Z" shape on the transition sprockets, significantly reduces the pressure on the two transition sprockets on opposite sides, thereby preventing damage to the transition sprockets due to gravity. Specifically, compared to the traditional "N"-shaped arrangement of transition sprockets and circulating chains, two transition sprockets can bear the weight of the circulating chain, and the number of transition sprockets can be increased in the height direction, further reducing damage to the transition sprockets.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the novel hinged structure material-covering cart of this application embodiment includes: a frame 100, a storage cabinet, a chain circulation traction system 200, and a material-covering cloth. The frame 100 is a hollow frame structure. The storage cabinet is mounted on the frame 100 and located inside the frame 100. The chain circulation traction system 200 is located on the top of the frame 100 and can drive the material-covering cloth to be laid from one end of the top of the storage cabinet to the other end of the storage cabinet. The chain circulation traction system 200 includes: a running guide rail, a transition sprocket 210, and a circulating chain 2. The frame 100 is equipped with a motor 230 and two running guide rails, which are arranged parallel to each other on the top sides of the frame 100 along its length. Multiple transition sprockets 210 are arranged on both sides of the frame 100 in the width direction and sequentially in the height direction. A circulating chain 220 is arranged on the transition sprockets 210 and the running guide rails and can slide on the running track. The cover cloth is laid on the circulating chain 220 on both sides. The motor 230 drives the circulating chain 220 to move from one end of the running track to the other end, controlling the cover cloth to be laid out or retracted.

[0034] In this embodiment, the circulating chain 220 is arranged in a "Z" shape on the transition sprocket 210, which greatly reduces the pressure on the two transition sprockets 210 on opposite sides, thereby preventing the circulating chain 220 from damaging the transition sprockets 210 due to gravity. Specifically, compared to the traditional "N" shaped arrangement of the transition sprockets 210 and circulating chain 220, two transition sprockets 210 can be used to bear the weight of the circulating chain 220, and the number of transition sprockets 210 can be increased in the height direction, further reducing damage to the transition sprockets 210.

[0035] The chain circulation traction system 200, comprising a running guide rail, a transition sprocket 210, a circulating chain 220, and a motor 230, enables the automatic unfolding and retraction of the covering cloth, significantly reducing the burden of manual operation and improving work efficiency. Its automation characteristics are particularly prominent in large warehouses or production lines where materials need to be frequently covered or uncovered. Driven by the motor 230, the circulating chain 220 can quickly move from one end of the running track to the other, rapidly unfolding or retracting the covering cloth. This allows the covering cart to respond quickly to covering needs, effectively reducing the time materials are exposed to the external environment and improving covering efficiency.

[0036] In one specific embodiment, each circulating chain 220 is also arranged in a "Z" shape between the transition sprockets 210, with the transition sprockets 210 on both sides corresponding and located on the same horizontal plane. Any two sets of corresponding transition sprockets 210 are parallel on the plane after the circulating chains 220 are mounted.

[0037] Furthermore, in this specific embodiment, adjacent transition sprockets 210 are spaced apart by a preset distance in the height direction. The distance between adjacent transition sprockets 210 in the height direction can be set according to the length of the circulating chain 220. When the storage cabinet is too large, the distance between adjacent transition sprockets 210 and the length of the circulating chain 220 can be increased accordingly.

[0038] In one specific embodiment, it further includes a support rod 300, the two ends of which are fixed to the circulating chains 220 located on both sides, further enhancing the stability and reliability of the cover fabric during unfolding and retraction. Specifically, the two ends of the support rod 300 are fixed to the circulating chains 220 located on both sides, and the support rod 300 can work in coordination with the movement of the circulating chains 220. When the motor 230 drives the circulating chains 220 to move from one end of the running track to the other end, the support rod 300 also moves accordingly, providing a stable support surface for the cover fabric.

[0039] Furthermore, in this specific embodiment, the support rod 300 is a rod-shaped structure, and there are multiple support rods 300, which are spaced apart along the length of the circulating chain 220. This effectively avoids problems such as wrinkles, sagging, or tearing that may occur during the movement of the cover cloth, ensuring that the cover cloth can always remain flat and taut, thereby improving the covering effect and the reliability of material protection.

[0040] In one specific embodiment, sprockets 210 are provided at both ends of the running track in the track direction. A circulating chain 220 is wrapped around the sprockets 210, driving the protective cloth to slide at both ends of the running track in the track direction, thereby achieving smooth operation of the circulating chain 220 and effective driving of the protective cloth. Specifically, the sprockets 210 are installed at both ends of the running track, serving as support and guide points for the circulating chain 220, ensuring that the circulating chain 220 can move smoothly and stably along the predetermined track direction. The circulating chain 220 wraps around these sprockets 210, forming a closed loop path. When the motor 230 starts, it drives the sprockets 210 to drive the circulating chain 220 to move continuously along this path. As the circulating chain 220 moves, the protective cloth laid on it also slides accordingly.

[0041] In one specific embodiment, the masking cloth is made of pure cotton material, and the surface of the masking cloth is coated with PE adhesive.

[0042] In one specific embodiment, the running track is located inside the frame 100, and the covering cloth can work with the frame 100 on both sides to completely cover the top of the storage cabinet.

[0043] In one specific embodiment, it further includes: a housing 240, which is a hollow structure with an open bottom, has a predetermined length, and a width equal to the width of the frame 100. The housing 240 covers the outside of the multiple transition sprockets 210 and the motor 230, and can protect the circulating chain 220 and the transition sprockets 210.

[0044] Furthermore, in this specific embodiment, the transition sprocket 210 is rotatably disposed on the inner wall of the housing 240.

[0045] According to the above embodiment, the frame 100 is a hollow frame structure, and the storage cabinet is located inside the frame 100. The chain circulation traction system 200 includes a running guide rail, a transition sprocket 210, a circulation chain 220, and a motor 230. The running guide rail is arranged parallel to both sides of the top of the frame 100, and the transition sprockets 210 are arranged on both sides of the frame 1001 in the width direction and sequentially along the height direction. The circulation chain 220 is arranged on the transition sprockets 210 and the running guide rail, and the cover cloth is laid on the circulation chains 220 on both sides. The motor 230 drives the circulation chain 220 to move from one end of the running track to the other end, thereby controlling the cover cloth to be laid out or retracted. The two ends of the support rod 300 are fixed to the circulation chains 220 located on both sides, forming a stable support structure. Sprockets 210 are provided at both ends of the running track in the track direction, and the circulation chain 220 is wrapped around the sprockets 210. The cover cloth is made of pure cotton material and coated with PE adhesive. The housing 240 covers the multiple transition sprockets 210 and the motor 230, providing protection. During use, when material needs to be covered, the motor 230 starts, driving the circulating chain 220 from one end of the running track to the other, thus spreading the covering cloth from one end of the storage tank to the other. When the covering cloth needs to be retracted, the motor 230 starts again, driving the circulating chain 220 from one end of the running track to the other, thus retracting the covering cloth.
