Description

A dual-purpose feeding weighbridge Technical Field

[0001] This utility model belongs to the field of weighbridge technology, specifically relating to a dual-purpose feeding weighbridge. Background Technology

[0002] During the weighing and metering process of IBC (Illuminated Batch Capacity) containers, the containers must be lifted by a forklift and placed on the weighbridge for measurement. However, in actual production, workshop layouts may make forklift operation inconvenient and container loading cumbersome. Currently, a common technical solution is to replace conventional weighbridges with U-shaped weighbridges, allowing forklifts to enter the central area and lower the containers. However, the larger gap in the U-shaped weighbridge prevents the placement of small, conventional chemical drums. A single weighbridge cannot accommodate both IBC containers and small chemical drums. IBC containers typically have a capacity of up to 1000 liters and a larger horizontal width; small chemical drums have smaller capacities and smaller widths. Existing solutions sometimes involve placing a flat plate on the U-shaped weighbridge. The plate is removed for IBC container measurement to facilitate forklift access, and reattached for small chemical drum measurement. This method is time-consuming and labor-intensive, and the weighbridge needs to be zeroed after loading and unloading the plate, making it inconvenient. Summary of the Invention

[0003] The purpose of this utility model is to address all or part of the shortcomings of the existing technology by providing a dual-purpose feeding weighbridge that is easy to operate, highly applicable, and compatible with the feeding, weighing, and measurement of IBC tonnes and small chemical drums.

[0004] A dual-purpose weighbridge includes a U-shaped weighbridge. The top of the U-shaped weighbridge has an adjustment frame whose shape matches the upper surface of the weighbridge. The adjustment frame includes opposing first and second inner sidewalls, and a connecting portion for connecting the first and second inner sidewalls. Corresponding strip grooves are formed on both the first and second inner sidewalls. Several sliding plates are sequentially installed in the strip grooves along the U-shaped opening direction. One end of each sliding plate is located in the strip groove of the first inner sidewall, and the other end is located in the strip groove of the second inner sidewall. The adjustment frame is equipped with a storage control component for separating or merging the sliding plates towards the connecting portion. In the separated state, small chemical drums are placed on the sliding plates for weighing; in the merged state, IBC (Isolated Ton Bag) containers are placed on the adjustment frame for weighing. In actual use, the state of each sliding plate can be flexibly adjusted according to the object being measured. When weighing IBC tonnes, the sliding plates are combined using the storage control component. This creates ample space in the center of the U-shaped weighbridge, allowing a forklift to enter and place the IBC tonnes on the adjustment frame for weighing. For weighing small chemical drums, the sliding plates are separated, and the drums are placed directly on them. Compared to existing U-shaped weighbridges, this dual-purpose feeding weighbridge offers greater compatibility. Both IBC tonnes and small chemical drums can be easily and quickly fed and placed. Mode switching is simple, requiring no zeroing of the weighbridge during mode switching, saving time and effort, and offering high practical value.

[0005] The storage control assembly includes a winding mechanism located inside the connecting part and a traction rope fixed at one end to the winding mechanism for merging the sliding pieces. Each sliding piece has a threading hole; the other end of the traction rope passes through the adjusting frame and sequentially through the threading holes of each sliding piece, then is fixed to the side of the last sliding piece in the arrangement. The winding mechanism controls the winding of the traction rope, pulling the sliding pieces towards the connecting part, thus simultaneously controlling the merging of each sliding piece towards the connecting part. This merging facilitates the weighing of the IBC container. This merging method is simple and convenient to operate.

[0006] The end of the traction rope furthest from the winding mechanism is fixed with a limiting block whose diameter is larger than the threading hole. The limiting block is located at the end of the last sliding piece in the arrangement. The limiting block allows the traction rope to drag the limiting block after being wound by the winding mechanism. The limiting block pushes each sliding piece towards the connecting part of the adjusting frame, i.e., towards the inside, causing the sliding pieces to merge. This creates a larger area in the middle of the U-shaped weighbridge, facilitating the unloading of IBC containers by forklifts after they have been transported into the middle of the U-shaped weighbridge.

[0007] The connecting part of the adjustment frame has an internal mounting groove, and the storage control component is installed in the mounting groove and located in the middle of the mounting groove; the threading hole is located in the middle of the sliding piece. Positioning the storage control component in the middle of the connecting part and the threading hole in the middle of the sliding piece makes the winding control of the traction rope and the merging process of the sliding piece more stable.

[0008] The winding mechanism includes a winding reel and a drive motor. The output shaft of the drive motor is connected to the winding reel, and one end of the traction rope is fixed to the winding reel. The drive motor controls the winding reel, thereby realizing the winding operation of the traction rope.

[0009] The winding mechanism also includes a reinforcing base, which is fixedly installed in the mounting groove. The shaft of the winding reel facing away from the drive motor is mounted on the reinforcing base via a rotating shaft. The reinforcing base effectively increases the structural stability of the winding reel.

[0010] The outer wall of the adjustment frame is equipped with a switch for controlling the start and stop of the drive motor, making the winding operation simple and quick.

[0011] A guide rod extending along the arrangement direction of the sliding pieces is fixedly installed inside the strip-shaped groove, and both ends of each sliding piece are sleeved on the guide rod. Under the action of the guide rod, each sliding piece maintains stable sliding and will not experience positional displacement that would prevent it from becoming immobile.

[0012] The storage control assembly also includes a return spring, which is used to separate the sliding pieces to achieve a reset. Adjacent sliding pieces are connected by at least two return spring segments. The return springs are disposed within strip-shaped grooves in the first and second inner sidewalls and are fixedly connected to adjacent sliding pieces at both ends. When the sliding pieces are combined, the return springs located between adjacent sliding pieces are compressed. Without the action of other forces, the return springs separate the sliding pieces, providing a supporting force for separation. This allows for convenient and quick adjustment of the sliding piece positions, thereby adjusting the usage mode and switching between the weighing modes of the IBC ton and small chemical drums.

[0013] The U-shaped weighbridge is equipped with feet at the bottom, and the sliding plates are rectangular. The feet increase the stability of the overall structure on the ground, and the rectangular shape helps to tightly connect the sliding plates together.

[0014] This utility model has at least the following beneficial effects:

[0015] This application uses a U-shaped weighbridge as its main structure. Several movable sliding plates are installed on this structure via an adjustable frame. The state of each sliding plate can be flexibly adjusted according to actual needs. When weighing IBC containers, the sliding plates are combined using a storage control component. This creates a large space in the middle of the U-shaped weighbridge, allowing a forklift to enter and place the IBC container on the adjustable frame for weighing. When weighing small chemical drums, the sliding plates are separated, allowing the small chemical drums to be placed on them for weighing. This invention is compatible with both IBC containers and small chemical drums, is easy to operate, and does not require zeroing the weighbridge when switching modes, making it highly practical.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5. A dual-purpose feeding weighbridge includes a U-shaped weighbridge 1. The bottom of the U-shaped weighbridge 1 is equipped with feet 7 to increase the stability of the overall structure when placed on the ground. The top of the U-shaped weighbridge 1 is provided with an adjustment frame 2 whose shape matches the upper surface of the U-shaped weighbridge 1. That is, the main frame of the adjustment frame 2 is also a U-shaped frame, and the adjustment frame 2 and the U-shaped weighbridge 1 are stacked together, with their shapes largely overlapping. The adjustment frame 2 includes opposing first inner sidewalls 201 and second inner sidewalls 202, and a connecting part 203 for connecting the first inner sidewalls 201 and the second inner sidewalls 202.

[0024] Both the first inner wall 201 and the second inner wall 202 are provided with corresponding strip grooves 204. Several sliding pieces 3 are sequentially installed within the strip grooves 204 along the U-shaped opening direction. One end of each sliding piece 3 is located within the strip groove 204 of the first inner wall 201, and the other end is located within the strip groove 204 of the second inner wall 202. A guide rod 4 extending along the arrangement direction of the sliding pieces 3 is fixedly installed within the strip groove 204. Both ends of each sliding piece 3 are sleeved on the guide rod 4, and guide rods 4 are fixedly installed within each pair of opposite strip grooves 204. The sliding pieces 3 are rectangular pieces, but in other embodiments, they can be other shapes, such as irregularly shaped pieces. The number of sliding pieces 3 can be five, or more or fewer depending on actual needs, but at least one sliding piece 3 is included to facilitate switching between the weighing modes of IBC containers and small chemical drums.

[0025] The adjustment frame 2 is equipped with a storage control component. A mounting groove 205 is provided inside the connecting portion 203 of the adjustment frame 2. A portion (or the main body or all) of the storage control component is installed in the mounting groove 205 and is located in the middle of the mounting groove 205. In this embodiment, the mounting groove 205 is a space inside the adjustment frame 2, only opened inside the connecting portion 203 and not exposed. In other embodiments, the mounting groove 205 can be exposed. The storage control component is used to separate or merge the sliding pieces 3 towards the connecting portion 203. The storage control component includes a winding mechanism disposed inside the mounting groove 205 and a traction rope 501 fixed at one end to the winding mechanism. The winding mechanism includes a winding wheel 502, a drive motor 503, and a reinforcing seat 504. The output shaft of the drive motor 503 is connected to the winding wheel 502. The drive motor 503 controls the winding wheel 502, thereby realizing the winding operation of the traction rope 501. The reinforcing base 504 is fixedly installed in the mounting groove 205. The shaft of the end of the winding reel 502 facing away from the drive motor 503 is mounted on the reinforcing base 504 via a rotating shaft, effectively increasing the structural stability of the winding reel 502. A switch for controlling the opening and closing of the drive motor 503 is provided on the outer wall of the adjusting frame 2, making operation simple and quick.

[0026] A threading hole is provided inside the sliding piece 3, and the threading hole is located in the middle of the sliding piece 3. One end of the traction rope 501 is fixed to the winding wheel 502, and the other end passes through the adjusting frame 2 and then sequentially passes through the threading hole of each sliding piece 3 and is fixed to the side of the last sliding piece 3 in the arrangement. A limiting block 505 with a diameter larger than the threading hole is fixed to the end of the traction rope 501 away from the winding mechanism. The limiting block 505 is located at the end of the last sliding piece 3 in the arrangement, so that the traction rope 501 drags the limiting block 505 to move after being wound by the winding wheel 502, thereby driving the sliding piece 3 to move. The winding mechanism and the traction rope 501 are used to merge the sliding pieces 3 together.

[0027] The storage control component also includes a reset spring 6, which is used to separate each sliding piece 3 to achieve reset; adjacent sliding pieces 3 are connected by at least two reset springs 6, and the reset springs 6 are set in the strip grooves 204 of the first inner sidewall 201 and the second inner sidewall 202 and are fixedly connected to the adjacent sliding pieces 3 by means of the two ends of the reset springs 6 respectively.

[0028] The principle and operation process of this embodiment 1 are as follows:

[0029] Weighing and measuring small chemical drums: The pressure of the return spring 6 is used to separate each sliding piece 3, that is, each sliding piece 3 slides along the guide rod 4 in the strip groove 204 away from the connecting part 203 and separates from each other (see Figure 1). The small chemical drum is placed directly on the sliding piece 3 for weighing.

[0030] IBC Tonnage Weighing Measurement: The drive motor 503 starts the winding wheel 502 to begin winding, and the traction rope 501 pulls the sliding plates 3, causing each sliding plate 3 to be in a combined state. That is, under the action of the traction rope 501 and the limit block 505, each sliding plate 3 slides along the guide rod 4 in the strip groove 204 towards the connecting part 203 and comes together (see Figure 5). At this time, the return spring 6 is compressed to a very small length, so when the sliding plates 3 are completely tightly combined, the return spring 6 between the sliding plates 3 will not be exposed, or at least not clearly visible. When each sliding plate 3 is in a combined state, a larger space is freed up in the middle area of ​​the U-shaped weighbridge 1, making it easier for the forklift to transport the IBC tonnage into the middle of the U-shaped weighbridge 1 and unload the tonnage. The tonnage is then placed on the adjusting frame 2 for weighing. Figure 5 is only a simplified illustration. In reality, when the width of each sliding plate 3 is narrower, or when fewer sliding plates 3 are set, a larger space will be freed up in the middle area of ​​the U-shaped weighbridge 1 to prevent interference between the forklift and the sliding plates 3. Even in other embodiments where the sliding plates 3 are narrower or fewer in number, as long as the spacing of the sliding plates 3 is properly arranged, they can still be adapted to fit small chemical drums when separated. Of course, in addition to adjusting the number of sliding plates 3, the risk of hydraulic forklifts hitting the sliding plates 3 can also be eliminated by extending the length of the first inner sidewall 201 and the second inner sidewall 202 on the adjusting frame 2 and the length of both sides of the U-shaped weighbridge 1.

[0031] If it is necessary to switch to the small chemical drum weighing mode after weighing the IBC ton drum, the drive motor 503 is used to make the winding wheel 502 start unwinding (unwinding the line). At this time, the return spring 6 is no longer subject to the traction force of the traction rope 501. Without the action of other forces, the return spring 6 will open each sliding piece 3 into a separated state. The return spring 6 provides a separation support force for each sliding piece 3.

[0032] In practical use, the dual-purpose feeding weighbridge provided in this embodiment uses a winding mechanism to merge the sliding plates 3. The winding wheel 502 controls the winding of the traction rope 501, simultaneously controlling the retraction of each sliding plate 3 to achieve feeding and weighing of IBC containers. When the sliding plates 3 merge, the return spring 6 is compressed. When the winding mechanism releases the wire, the rebound force of the return spring 6 simultaneously separates each sliding plate 3. This combination allows for convenient and quick adjustment of the position of the sliding plates 3, thereby adjusting the usage mode. The state between each sliding plate 3 can be flexibly adjusted according to the object being measured. Compared to the existing U-shaped weighbridge 1, it has stronger compatibility, allowing for convenient and quick feeding and placement of both IBC containers and small chemical drums. The mode switching operation is simple and quick, requiring no zeroing of the weighbridge, saving time and effort. It is highly applicable and practical.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
