Description

Technical Field

[0001] This utility model relates to the field of electronic scale technology, specifically to an electronic scale that can automatically feed materials. Background Technology

[0002] An electronic scale is a device that uses electronic technology to weigh items. It is widely used in industry, commerce, agriculture, and other fields. Electronic scales convert weight into electrical signals through sensors, and then display the weight data in real time on a monitor. Electronic scales typically feature high precision, digital display, ease of operation, and multifunctionality. They can automatically deduct the weight of containers, displaying only the net weight of the item. The high precision and fast response of electronic scales improve the efficiency of the weighing process.

[0003] Chinese Patent Publication No. CN219319551U discloses an electronic weighing device, including an electronic scale and a material transport vehicle. The electronic scale includes a weighing platform with a sloping ramp at one end. Two weighing channels are provided on the weighing platform, with one end of each channel facing the ramp and open, and the other end closed. The weighing platform also has a weighing display screen, which shows the weighing result. The material transport vehicle includes a basket with two wheels at the bottom, allowing it to travel within the two weighing channels. A removable filter screen is located at the top of the basket. This invention eliminates the need for lifting when feeding construction materials onto the scale, saving manpower and improving weighing efficiency.

[0004] The aforementioned patent mentions that although the weighing device avoids the need for workers to lift materials through its ramp structure and wheel design, reducing vertical manpower consumption, workers still need to manually push the material-loaded transport vehicle along the ramp and precisely position it in the weighing area of ​​the electronic scale. During this process, construction materials typically have considerable weight, and the transport vehicle exhibits significant overall inertia while loaded. Workers need to continuously apply pushing force to overcome frictional resistance and inertial forces, still requiring considerable physical exertion. This reliance on manual pushing extends the operation time of a single weighing in high-frequency weighing scenarios, reducing the weighing frequency per unit time and thus affecting the weighing efficiency of the electronic scale. Therefore, we propose an electronic scale with automatic material loading. Utility Model Content

Detailed Implementation

[0029] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0030] See Figures 1-5As shown, an electronic scale capable of automatic feeding includes an electronic scale body 1, a material cart 11 disposed inside the electronic scale body 1, a force transmission component 12 disposed on the electronic scale body 1, and a push plate 2 disposed on the side of the electronic scale body 1 near the material cart 11 for cooperating with the material cart 11 to move; a drive mechanism for providing linear displacement power to the push plate 2 is disposed between the electronic scale body 1 and the push plate 2; an angle adjustment mechanism for driving the push plate 2 to rotate horizontally towards the material cart 11 is disposed between the push plate 2 and the drive mechanism; and a [missing information - likely a design element] is disposed between the electronic scale body 1 and the force transmission component 12. A displacement mechanism is provided for driving the force transmission component 12 to move below and upward under the material cart 11; the driving mechanism includes a connecting block 21, a screw 22 and a power assembly 23; the connecting block 21 is disposed on the electronic scale body 1 and is rotatably disposed on the upper side of the push plate 2; the screw 22 is rotatably disposed on the electronic scale body 1 and is threadedly connected to the connecting block 21; the power assembly 23 is disposed on the electronic scale body 1 and the working end of the power assembly 23 is fixedly connected to one end of the screw 22, and the power assembly 23 is used to provide power for the rotation of the screw 22.

[0031] Specifically, the force transmission component 12 can transmit the weight of the object to the weighing sensor of the electronic scale body 1. The power component 23 consists of a meshing synchronous pulley, a synchronous belt, and a motor, wherein the synchronous pulley is fixedly connected to one end of the screw 22, and the output end of the motor is fixedly connected to the synchronous pulley. A guide rail sliding guide pair is configured between the connecting block 21 and the electronic scale body 1, which is used to limit the rotation of the connecting block 21 with the screw 22.

[0032] When the main body 1 of the electronic scale is running, the material cart 11 is first moved between the two push plates 2. The power assembly 23 is started, and the motor drives the screw 22 to rotate through the meshing transmission of the synchronous pulley and the synchronous belt. Since the connecting block 21 is threadedly connected to the screw 22, and under the limiting action of the sliding guide pair of the guide rail, the connecting block 21 drives the push plate 2 to move linearly. At this time, the push plate 2 rotates under the drive of the angle adjustment mechanism until it approaches the material cart 11 and is positioned behind its rollers. Subsequently, the push plate 2 continues to move under the action of the drive mechanism, driving the material cart 11 closer to the force transmission component 12. At the same time, the push plate 2 rotates in the opposite direction through the angle adjustment mechanism and is positioned in front of the rollers of the material cart 11 to achieve a limit and prevent the material cart 11 from deviating from the force transmission component 12.

[0033] The displacement mechanism moves the force transmission component 12 to below the material cart 11 and lifts it upwards, causing the force transmission component 12 to raise the material cart 11, and the electronic scale body 1 completes the weighing. This process eliminates the need for manual pushing of the material cart 11, which can improve work efficiency, reduce human operation errors and safety risks, and save labor costs.

[0034] After weighing is completed, the push plate 2 is positioned in front of the rollers of the material cart 11, allowing the displacement mechanism to move the material cart 11 down to reset. The power component 23 is activated to make the connecting block 21 move the push plate 2 in the opposite direction, causing the material cart 11 to detach from the main body of the electronic scale 1, making it easier for staff to move the material cart 11, reducing the tedious manual handling, thus saving time and improving work efficiency.

[0035] See Figures 1-4 and Figures 8-11 As shown, the angle adjustment mechanism includes a first toothed disc 24, a first toothed plate 25, and a second toothed plate 26; the first toothed disc 24 is fixedly connected to the lower side of the push plate 2, and the first toothed disc 24 is movably connected to the support plate 241; the first toothed plate 25 meshes with the first toothed disc 24, and the first toothed plate 25 is fixedly connected to the electronic scale body 1; the second toothed plate 26 is disposed on the side of the electronic scale body 1 away from the first toothed plate 25, and the second toothed plate 26 meshes with the first toothed disc 24; the angle adjustment mechanism also includes a third toothed plate 27, a first power component 28, a guide assembly, and an elastic reset component 29; the third toothed plate 27 meshes with the first toothed disc 24, and the third toothed plate 27 is disposed on the support plate 241; the first power component 28 is fixedly connected to the support plate 241, the first toothed plate 27 meshes with the first toothed disc 24, and the third toothed plate 27 is disposed on the support plate 241; the first power component 28 is fixedly connected to the support plate 241, the first toothed plate 25 is fixedly connected to the push ... The output end of a power component 28 is fixedly connected to a third toothed plate 27; a guide assembly is disposed between a second toothed plate 26 and the electronic scale body 1, and the guide assembly is used to assist the second toothed plate 26 in linear movement; an elastic reset component 29 is disposed on the guide assembly, and the elastic reset component 29 is used to cooperate with the second toothed plate 26 to restore its original position; the guide assembly includes a slide groove 210 and a first slider 211; the slide groove 210 is opened on the side of the electronic scale body 1 near the second toothed plate 26; the first slider 211 slides in cooperation with the slide groove 210, and the first slider 211 is fixedly connected to the second toothed plate 26; the elastic reset component 29 is disposed in the slide groove 210, and the two ends of the elastic reset component 29 are fixedly connected to the slide groove 210 and the first slider 211, respectively.

[0036] Specifically, a sliding guide pair is configured between the support plate 241 and the main body 1 of the electronic scale. The sliding guide pair is used to limit the rotation of the support plate 241 with the screw 22. The first power component 28 uses an electric telescopic rod as the implementing element. The third toothed plate 27 and the support plate 241 are configured with a sliding guide pair, which is used to cooperate with the third toothed plate 27 to achieve stable linear movement. The elastic reset component 29 uses a spring as the implementing element. The slide groove 210 and the first slider 211 form a sliding guide pair.

[0037] When the connecting block 21 drives the push plate 2 to move linearly, the push plate 2 simultaneously drives the first toothed disc 24, the support plate 241, the first power component 28, and the third toothed plate 27 to move. At this time, the output end of the first power component 28 drives the third toothed plate 27 away from the first toothed disc 24, so that the first toothed disc 24 docks with the first toothed plate 25; as the push plate 2 moves, the first toothed disc 24 rotates under the action of the first toothed plate 25, simultaneously driving the push plate 2 to rotate to the rear side of the material cart 11 roller.

[0038] When the first power component 28 is activated, the output end of the first power component 28 pushes the third toothed plate 27 closer to the first toothed disc 24. The guide rail sliding pair configured between the support plate 241 and the third toothed plate 27 can cooperate with the third toothed plate 27 to achieve stable linear movement, so that the third toothed plate 27 and the first toothed disc 24 can be precisely meshed and connected. At this time, the push plate 2 rotates and is located behind the roller of the material cart 11, and pushes the material cart 11 to move towards the force transmission component 12 through the drive mechanism.

[0039] After the material cart 11 stops moving, the first power unit 28 is restarted. The output end of the first power unit 28 drives the third toothed plate 27 to move and disengage from the first toothed disc 24. The drive mechanism continues to drive the connecting block 21 to move the push plate 2, so that the first toothed disc 24 engages with the second toothed plate 26. At the same time, the elastic reset member 29 supports the second toothed plate 26 to stably engage with the first toothed disc 24, causing the push plate 2 to rotate in the opposite direction to the front of the roller of the material cart 11. Then the first power unit 28 is restarted to push the third toothed plate 27 to engage with the first toothed disc 24, restricting the rotation of the first toothed disc 24.

[0040] After the material cart 11 is weighed, the drive mechanism drives the connecting block 21 to move the push plate 2 closer to the material cart 11. At this time, the first toothed disc 24 and the second toothed plate 26 are pressed together, causing the second toothed plate 26 to drive the first slider 211 to slide along the slide groove 210. The sliding guide pair formed by the slide groove 210 and the first slider 211 can prevent the first slider 211 from shaking or deviating. At the same time, the first slider 211 presses the elastic reset member 29, causing the elastic reset member 29 to contract and move the second toothed plate 26 away from the first toothed disc 24 to avoid interfering with the movement of the push plate 2. The push plate 2 then pushes the material cart 11 away from the electronic scale body 1, realizing the automatic weighing and unloading of the material cart 11.

[0041] By automatically loading and unloading materials onto the scale using material carts 11, manual intervention can be reduced, and the weighing and unloading of multiple material carts 11 can be completed in a short time without the need for staff to manually operate the material carts 11, thus improving the efficiency of electronic scale operation.

[0042] See Figures 1-3 , Figure 6 and Figure 7As shown, the displacement mechanism includes a support block 212, a second power component 213, and a bevel gear assembly 214. The support block 212 is mounted on the main body 1 of the electronic scale. The output end of the second power component 213 is fixedly connected to the support block 212. The bevel gear assembly 214 is rotatably mounted inside the support block 212. One working end of the bevel gear assembly 214 is fixedly connected to a second gear disc 215. The second gear disc 215 is rotatably mounted on the support block 212. The second gear disc 215 meshes with a fourth gear plate 216, and the fourth gear plate 216 is fixedly connected to the main body 1 of the electronic scale. The displacement mechanism also includes a guide post 217 and a second slider 218. The guide post 217 is rotatably mounted inside the support block 212. The guide post 217 is fixedly connected to the working end of the bevel gear assembly 214 away from the second gear disc 215. A guide groove is provided on the surface of the guide post 217. The second slider 218 slides in cooperation with the guide groove.

[0043] Specifically, the second power component 213 uses an electric telescopic rod as the implementing element. The bevel gear assembly 214 consists of meshing bevel gears. The guide groove and the second slider 218 form a sliding guide pair. A guide rail sliding guide pair is configured between the support block 212 and the electronic scale body 1. The guide rail sliding guide pair is used to cooperate with the support block 212 to make stable linear movement. The guide groove of the guide post 217 forms a sliding guide pair with the second slider 218. A straight groove is opened on the support block 212, and the straight groove forms a sliding guide pair with the bottom plate of the force transmission component 12.

[0044] When the material cart 11 moves toward the force transmission component 12, the force transmission component 12 is housed inside the main body 1 of the electronic scale to avoid interfering with the movement of the material cart 11. After the material cart 11 approaches the force transmission component 12 and stops moving, the second power component 213 is activated. The output end of the second power component 213 pushes the support block 212 to move downwards from the material cart 11. During the movement of the support block 212, it drives the second gear disk 215 to rotate along the fourth gear plate 216. Through the bevel gear assembly 214 composed of meshing bevel gears, the second gear disk 215 drives the guide column 217 to rotate synchronously.

[0045] When the guide post 217 rotates, the guide groove of the guide post 217 and the second slider 218 press against each other, and the guide groove and the second slider 218 form a sliding guide pair; at the same time, the straight groove on the support block 212 and the bottom plate of the force transmission component 12 form a sliding guide pair. Under the dual guiding action, the second slider 218 drives the force transmission component 12 to move vertically upward, so that the force transmission component 12 lifts the material cart 11 and transmits the weight of the material cart 11 to the weighing sensor of the electronic scale body 1.

[0046] After the material cart 11 is automatically transferred to the main body of the electronic scale 1, automatic weighing can be completed. The automated process ensures that the material cart 11 can complete the weighing operation quickly and continuously, reducing delays caused by human intervention, thereby improving the speed and efficiency of the overall operation.

[0047] Working principle: When the main body 1 of the electronic scale is running, the material cart 11 is first moved between the two push plates 2. The power component 23 is started, and the connecting block 21 drives the push plate 2 to move linearly. The first toothed disc 24 and the first toothed plate 25 are connected to move the push plate 2. Then the first power component 28 is started. After the push plate 2 rotates, it is limited to the rear side of the roller of the material cart 11. At this time, the connecting block 21 continues to drive the push plate 2 to move linearly, so that the push plate 2 pushes the material cart 11 to move closer to the force transmission component 12. At this time, the second power component 213 is started, so that the support block 212 moves downward to the material cart 11. At the same time, the force transmission component 12 moves vertically upward to lift the material cart 11. The force transmission component 12 then transmits the weight of the material cart 11 to the weighing sensor of the main body 1 of the electronic scale, so that the material cart 11 is automatically moved to the main body 1 of the electronic scale, and automatic weighing is completed.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
