Description

Technical Field

[0001] The utility model relates to the technical field of combination scale assembly, in particular to a single-shell load-bearing waterproof aluminum box. Background Art

[0002] When the weighing efficiency of a combination weigher needs to be improved, a common solution is to increase the number of weighing hoppers. In order to ensure that the weighing hoppers can accurately weigh the target weight of materials, a storage hopper is often set above the weighing hopper. By controlling the unloading rate of the storage hopper, the weighing hopper can be accurately unloaded to avoid situations such as over-unloading.

[0003] In the above scheme, each group of weighing units includes a storage hopper on the top and a weighing hopper on the bottom, and both the storage hopper and the weighing hopper are equipped with independent motor drive components to control the independent opening and closing of any storage hopper or any weighing hopper. It can be imagined that when there are a large number of weighing units, the assembly and maintenance work for the hopper and motor drive components will become extremely cumbersome, and the assembly of the above components requires the opening of a large number of hole slots on the main body of the combination scale, which has an adverse effect on the strength of the main body of the combination scale and may affect the weighing accuracy.

[0004] In addition, when weighing fresh food and other materials that may seep water, waterproofing measures must be taken on the combination scale. However, the many holes and grooves on the main body of the combination scale will increase the difficulty of waterproofing and increase the failure rate of each component. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figures 1 to 5 The single-shell load-bearing waterproof aluminum box may include the following contents.

[0036] The box body 1 is formed by stamping, the middle part of the box body 1 is concave, and a step 11 is provided at the edge;

[0037] A transmission hole 12 and a sensor hole 13 are provided in the middle of the box body 1, and a plurality of screw holes 14 are provided in the step 11;

[0038] The device box 2 is assembled on the back of the box body 1, and the drive motor 21 and the transmission shaft 22 connected to the output end of the drive motor 21 are assembled inside the device box 2. The transmission shaft 22 protrudes from the front of the box body 1 through the transmission hole 12;

[0039] A sensor 23 is also installed inside the device box 2, and a detection end of the sensor 23 is arranged at the sensor hole 13;

[0040] The transmission shaft 22 and the transmission hole 12, as well as the sensor 23 and the sensor hole 13, are tightly connected by an oil seal 24;

[0041] A sealing ring S is assembled along the surface edge of the step 11 .

[0042] Here, the box body 1 formed by integral stamping is concave in the middle, and the edge step 11 is warped, achieving the effect of reinforcing ribs, making it have higher structural strength than conventional flat box bodies, and excellent weighing capacity, so that the storage hopper, weighing hopper, sensor, drive motor, transmission equipment and other equipment components originally assembled on the combination scale body can be assembled on the box body first, and power supply and signal interfaces are provided to form a weighing unit. Accordingly, the weighing unit can be easily assembled on the combination scale body, and there is no need to perform a large number of hole and slot operations on the combination scale, which will not have an adverse effect on the strength and weighing accuracy of the combination scale.

[0043] In addition, the hoppers assembled with weighing units greatly reduce the difficulty of assembly and maintenance. The failure of a single weighing unit will not affect the continued operation of the entire machine, and the reliability of the equipment is further improved.

[0044] In addition, the holes on the box body are sealed with oil seals and the box body and the combination scale body are sealed with sealing rings, so that the weighing unit has excellent waterproof performance and can be used for weighing and packaging materials with different properties.

[0045] In this embodiment, the box body 1 is fastened to the main structure of the combination weigher by screws;

[0046] The sealing ring S is tightly filled between the main structure of the combination weigher and the step 11 .

[0047] In this embodiment, a module panel 25 is installed at the rear of the device box 2, and the module panel 25 is electrically connected to the drive motor 21 and the sensor 23;

[0048] In this embodiment, the module panel 25 is also electrically connected to the central control unit of the combination weigher to transmit detection data of the sensor 23 to the central control unit, to transmit control instructions to the drive motor 21, and to supply power to the drive motor 21 and the sensor 23.

[0049] Here, the module panel 25 provides a universal interface for power supply and external communication for each component equipment on the weighing module, ensuring that the combination weigher can be easily assembled and modified without additional modification.

[0050] In this embodiment, a fixing plate 15 is disposed inside the transmission hole 12 and inside the sensor hole 13 , and the inner ring of the fixing plate 15 is tightly fitted to the outer edge of the oil seal 24 .

[0051] In this embodiment, a plurality of mounting holes 16 are provided on the outer edge of the fixing plate 15 for fastening and assembling the driving motor 21 or the sensor 23 with screws or rivets.

[0052] Here, the driving motor or sensor is assembled inside the box body without making additional process openings on the box body, so as to ensure the water tightness and structural strength of the box body.

[0053] In this embodiment, the fixing plate 15 cooperates with the oil seal 24 to position the transmission shaft 22 of the driving motor 21 at the center of the transmission hole 12 , and the relative distance between the limit sensor 23 and the surface of the box body 1 .

[0054] Here, the fixing plate and the oil seal cooperate to not only provide good water tightness and fixing effect, but also assist the transmission shaft to achieve center positioning, and assist in calibrating the relative position of the sensor, which is beneficial to improve the weighing accuracy.

[0055] In this embodiment, the outer edge of the sealing ring S is rolled back and covers the edge of the step 11;

[0056] Corresponding to the convex edge of the step 11, the sealing ring S is provided with a corresponding protrusion for filling and sealing.

[0057] In this embodiment, in order to ensure the sealing and waterproof effect, the outer edge of the entire box body step is covered by the sealing ring, and the sealing ring is also provided with additional protrusions corresponding to the uneven area at the step to ensure tight filling. Therefore, when the box body and the combination weigher body are fastened and installed, the sealing ring is fastened and squeezed on both sides, and the box body obtains excellent waterproof performance.

[0058] In this embodiment, each screw hole 14 of the step 11 is independently provided with a sealing ring.

[0059] Here, in order to ensure the waterproof performance of the screw connection between the box body and the combination scale body, a sealing ring independent of the sealing ring is also provided at the screw hole to eliminate the position where water leakage may occur.

[0060] In this embodiment, the number of the transmission holes 12 is at least two, which are used for the transmission shaft 22 to control the opening and closing of the storage hopper A and the weighing hopper B respectively.

[0061] Here, the weighing unit is composed of at least a storage hopper and a weighing hopper. When multi-stage weighing is required, a box structure with multiple transmission holes can be selected accordingly.

[0062] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0063] The hopper and other equipment are assembled on a box body with a strong structure formed by one-piece stamping to form a weighing unit, which is then assembled to the main body of the combination scale. There is no need to make a large number of holes and grooves on the main body of the combination scale, which does not affect the strength of the main body of the combination scale. In addition, each hole and joint of the box body is sealed with a sealing ring or oil seal, which has excellent waterproof performance.
