Description
Technical Field
[0001] This utility model relates to the field of weighing technology, and in particular to a weighing device. Background Technology
[0002] Traditional linear weighing devices generally use a dual-head vibratory feeding method with large and small vibrations. The large vibration completes the rapid feeding, while the remaining small portion is fed slowly by the small vibration until the set weight is reached. This method requires turning on the vibrating electromagnet at the bottom of the feeding channel to convert current into vibration to drive the material flow, which is inefficient and makes it difficult to complete the feeding process quickly.
[0003] A small number of weighing devices use arc valves with vibration feeding. The arc valves are driven by cylinders or motors, and the arc valves and vibration channels are independent of each other. Although the speed is fast, the size is huge. Utility Model Content
[0004] Therefore, it is necessary to provide a weighing device that addresses the common problem of traditional linear weighing devices that use a dual-head vibratory feeding method with large and small vibrators. The large vibrator completes the rapid feeding, while the small vibrator slowly feeds the remaining small portion until the set weight is achieved. This method requires turning on the vibrating electromagnet at the bottom of the feeding channel to convert current into vibration to drive the material flow, which is inefficient and makes it difficult to complete the feeding process quickly.
[0005] A small number of weighing devices use arc valves with vibration feeding. The arc valves are driven by cylinders or motors, and the arc valves and vibration channels are independent of each other. Although the speed is fast, the size is huge.
[0006] This utility model provides a weighing device, which includes a material storage component, a vibration component, and a weighing component. The material storage component includes a material storage hopper, a hopper door, and a drive module. The material storage hopper has a material storage cavity and a discharge channel connected to the material storage cavity. The drive module is drivenly connected to the hopper door and is used to drive the hopper door to open or close the discharge channel, so as to control the material to fall into the weighing component through the vibration component.
[0007] In one embodiment, the drive module includes a drive motor, a gear, and a rack. The hopper door is slidably connected to the storage hopper near the discharge channel. The drive motor is fixed to the storage hopper and to the gear. The gear is driven to the rack. The rack is fixed to the hopper door. The drive motor drives the gear to move the rack, and the rack moves the hopper door to open or close the discharge channel.
[0008] In one embodiment, the storage hopper is provided with a guide at the discharge channel, and the hopper door is slidably connected to the guide, the guide being used to guide the hopper door.
[0009] In one embodiment, the vibration assembly includes a vibrator and a feeding trough, the vibrator being drive-connected to the feeding trough.
[0010] In one embodiment, the feeding trough partially overlaps with the feeding channel in orthographic projection.
[0011] In one embodiment, the weighing assembly includes a weighing hopper and a sensor module, wherein the weighing hopper is detachably connected to the sensor module, and the sensor module is used to weigh the weighing hopper.
[0012] In one embodiment, the weighing assembly further includes a hook and a hanging plate, the hook being fixed to the weighing hopper, the hanging plate being fixed to the sensor module, and the hook being hung on the hanging plate.
[0013] In one embodiment, the sensor module includes a weighing sensor and a mounting plate, with the mounting plate fixed to the mounting plate via the weighing sensor.
[0014] In one embodiment, the sensor module further includes a bracket, and the mounting plate is fixed to the bracket.
[0015] In one embodiment, the weighing device further includes a frame, on which the material storage assembly, the vibration assembly, and the weighing assembly are all mounted.
[0016] Implementing the embodiments of this utility model will have the following beneficial effects: The weighing device of this invention has a storage hopper with a storage chamber and a discharge channel connected to the storage chamber. The drive module is connected to the hopper door and is used to drive the hopper door to open or close the discharge channel, so as to control the material to fall onto the weighing component through the vibration component. As the hopper door opens to a certain extent, the area of the material falling onto the vibration component gradually increases, and the speed of the material falling onto the weighing component gradually increases. When the hopper door is opened further, the area of the material falling onto the vibration component increases rapidly, and the speed of the material falling onto the weighing component increases dramatically, thereby achieving the purpose of rapid material discharge.
[0017] Furthermore, since the feeding channel and the vibration assembly are located at the same feeding position, the volume is greatly reduced. Attached Figure Description

[0026] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0028] Please combine them together Figures 1 to 3 The weighing device provided by this utility model will now be described.
[0029] The weighing device includes: a material storage component 1, a vibration component 2, and a weighing component 3. The material storage component 1 includes a material storage hopper 11, a hopper door 12, and a drive module 13. The material storage hopper 11 has a material storage chamber 111 and a discharge channel 112 connected to the material storage chamber 111. The drive module 13 is connected to the hopper door 12 and is used to drive the hopper door 12 to open or close the discharge channel 112, so as to control the material to fall from the vibration component 2 to the weighing component 3.
[0030] It is understood that the hopper 11 of the weighing device has a storage chamber 111 and a discharge channel 112 connected to the storage chamber 111. The drive module 13 is connected to the hopper door 12 and is used to drive the hopper door 12 to open or close the discharge channel 112, so as to control the material to fall from the vibration component 2 to the weighing component 3. As the hopper door 12 opens to a certain extent, the area of the material falling to the vibration component 2 gradually increases, and the speed of the material falling to the weighing component 3 gradually increases. When the hopper door 12 is opened further, the area of the material falling to the vibration component 2 increases rapidly, and the speed of the material falling to the weighing component 3 increases dramatically, thereby achieving the purpose of rapid material discharge.
[0031] Furthermore, since the feeding channel 112 and the vibration assembly 2 are located at the same feeding position, the volume is greatly reduced.
[0032] It should be noted that the feeding process can be divided into several stages. Each stage can be set with different positions of the bin door 12 and vibration amplitude of the vibration component 2. When the feeding is nearing the end, the opening of the bin door 12 and the vibration amplitude are set to form a good match, so that the feeding weight can be precisely controlled. Finally, the vibration of the vibration component 2 is turned off to complete the weighing. The opening of the bin door 12 and the vibration amplitude during the feeding process can be automatically judged and adjusted by the control system according to the weighing result weight and the required time to achieve a good match between weight accuracy and speed.
[0033] In this embodiment, the drive module 13 includes a drive motor 131, a gear 132, and a rack 133. The hopper door 12 is slidably connected to the storage hopper 11 near the discharge channel 112. The drive motor 131 is fixed to the storage hopper 11 and is also fixed to the gear 132. The gear 132 is drively connected to the rack 133, and the rack 133 is fixed to the hopper door 12. The drive motor 131 drives the gear 132 to move the rack 133, which in turn moves the hopper door 12 to open or close the discharge channel 112. This allows the hopper door 12 to move, thereby enabling it to open or close the discharge channel 112.
[0034] Of course, in other embodiments, the drive module 13 includes a drive motor 131, a lead screw and a lead screw nut. The drive motor 131 is fixed to the lead screw, the lead screw is connected to the lead screw nut, and the lead screw nut is fixed to the bin door 12. The drive motor 131 drives the lead screw to rotate, and the lead screw drives the lead screw nut and the bin door 12 to move, so as to open or close the feeding channel 112.
[0035] Furthermore, the storage hopper 11 is equipped with a guide 14 at the discharge channel 112, and the hopper door 12 is slidably connected to the guide 14, which guides the hopper door 12. The guide 14 can be a slide rail. The hopper door 12 moves along the direction of the guide 14, enabling the hopper door 12 to open or close the discharge channel 112.
[0036] In one embodiment, such as Figure 2 As shown, the vibration assembly 2 includes a vibrator 21 and a feeding trough 22, with the vibrator 21 connected to the feeding trough 22. The vibration generated by the vibrator 21 is transmitted to the feeding trough 22, allowing the material falling from the feeding channel 112 into the feeding trough 22 to fall onto the weighing assembly 3 through vibration. Different vibration frequencies generated by the vibrator 21 result in different vibration amplitudes in the feeding trough 22, thereby altering whether the feeding trough 22 accelerates or slows down the material flow.
[0037] Of course, in other embodiments, the vibrator can be replaced by a motor and a belt, with the motor driving the belt to move back and forth, and the belt then driving the feed trough 22 to vibrate back and forth.
[0038] In this embodiment, the feeding trough 22 partially overlaps with the feeding channel 112 under orthographic projection. When the silo door 12 is opened to a certain extent, the material in the feeding channel 112 can fall into the feeding trough 22. If the silo door 12 is opened further, part of the material in the feeding channel 112 falls into the feeding trough 22, and the other part falls directly into the weighing component 3, which can speed up the feeding process.
[0039] In one embodiment, such as Figure 3As shown, the weighing assembly 3 includes a weighing hopper 31 and a sensor module 32. The weighing hopper 31 is detachably connected to the sensor module 32, which is used to weigh the material in the weighing hopper 31. The weighing hopper 31 is detachable, allowing it to be cleaned periodically. The sensor module 32 weighs the material in the weighing hopper 31 until it reaches a preset weight.
[0040] In this embodiment, the weighing assembly 3 further includes a hook 33 and a hanging plate 34. The hook 33 is fixed to the weighing hopper 31, and the hanging plate 34 is fixed to the sensor module 32. The hook 33 is hung on the hanging plate 34. This allows the weighing hopper 31 to be disassembled.
[0041] Furthermore, the sensor module 32 includes a weighing sensor 321 and a mounting plate 322, with the hanging plate 34 fixed to the mounting plate 322 via the weighing sensor 321. The weighing sensor 321 is fixed via the mounting plate 322 and also to the hanging plate 34, thereby enabling the weighing hopper 31 to be weighed.
[0042] Furthermore, the sensor module 32 also includes a bracket 323, and a mounting plate 322 is fixed to the bracket 323. In this way, the load cell 321 is fixed to the bracket 323 via the mounting plate 322, so that the load cell 321 can be installed and fixed.
[0043] In one embodiment, the weighing device further includes a frame on which the material storage assembly 1, the vibration assembly 2, and the weighing assembly 3 are all mounted. This allows the material storage assembly 1, the vibration assembly 2, and the weighing assembly 3 to be installed.
[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
