Abstract
Description
Technical Field
[0001] This utility model relates to the field of raw material processing and measurement, and in particular to an automatic raw material crushing and weighing device. Background Technology
[0002] In the field of raw material processing and metering, existing crushing and weighing equipment is mostly designed as separate units, requiring manual transfer of crushed raw materials to the weighing device. This process is not only cumbersome and inefficient, but also prone to weighing errors due to manual operation, making it difficult to meet the needs of continuous production. Furthermore, traditional crushing equipment often uses a single-speed grinding roller structure, resulting in poor uniformity of raw material crushing and inconsistent particle sizes, affecting the quality of subsequent processing. While some integrated equipment attempts to combine functions, it lacks a scientific graded crushing design and a precise automated control system, leading to problems such as poor crushing effect, insufficient weighing accuracy, and unstable unloading control. In addition, the significant amount of manual intervention not only increases labor costs but also may cause raw material loss or equipment failure due to improper operation, failing to meet the core requirements of modern industrial production for high efficiency, precision, and automation.
[0003] While existing technologies can achieve certain crushing and weighing effects, they suffer from drawbacks: they lack scientific grading and crushing design and automated quantitative control functions. In view of this, we propose an automatic raw material crushing and weighing device that solves the above problems. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic raw material crushing and weighing device.
[0005] The technical solution of this utility model is as follows: An automatic raw material crushing and weighing device includes a first housing, a cover, and a first rotating motor. The cover is provided on one outer wall of the first housing, and the first rotating motor is fixedly connected to the outer wall of one side of the cover. The output shaft of the first rotating motor is fixedly connected to the outer wall of one side of the main gear. Two second driven gears and three first driven gears are provided on one outer wall of the first housing. The main gear meshes with one of the first driven gears and one of the second driven gears respectively. Adjacent first driven gears mesh with each other, and the second driven gears mesh with each other. The radius of the second driven gear is larger than the radius of the first driven gear. The first rotating motor drives the first driven gear and the second driven gear to rotate simultaneously, and the rotational speed of the second driven gear is less than that of the first driven gear.
[0006] When using one of the automatic raw material crushing and weighing devices in this solution, the raw material to be processed is first fed into the funnel-shaped feed inlet at the top of the first housing. The raw material falls through an inclined channel onto the second grinding roller. The first rotating motor is started, and the main gear drives the first and second driven gears of different radii to rotate synchronously, driving the corresponding grinding rollers to achieve high-speed and low-speed graded crushing. The raw material is first initially crushed by the low-speed grinding roller, and then finely processed by the high-speed grinding roller. After crushing, the raw material falls into the second housing. A pressure sensor detects the weight in real time and transmits a signal to the controller. When the weight reaches a preset threshold, the controller automatically closes the first baffle to stop feeding and simultaneously opens the second baffle, allowing the raw material to be quantitatively discharged from the outlet. After unloading, the controller adjusts the baffle to reset, allowing the next round of operation to begin. The entire process requires no manual intervention, is suitable for continuous production, and is convenient, efficient, and precise in operation.
[0007] Preferably, the first housing is provided with a plurality of first grinding rollers and second grinding rollers. One end of the first grinding roller is connected to a corresponding first driven gear, and the second grinding roller is connected to a corresponding second driven gear. The first grinding roller rotates synchronously with the first driven gear, and the second grinding roller rotates synchronously with the second driven gear.
[0008] Preferably, a mounting plate is fixedly connected to the lower outer wall of the first housing, and a second housing is provided on the lower outer wall of the mounting plate. The lower outer wall of the second housing is provided with a discharge port for unloading materials.
[0009] Preferably, the outer wall of one side of the second housing is provided with two sets of symmetrical second and third rotating motors. The output shaft of the second rotating motor is fixedly connected to one end of the corresponding first baffle, and the output shaft of the third rotating motor is fixedly connected to one end of the corresponding second baffle. Driving the second rotating motor can adjust the opening and closing between the two first baffles, and driving the third rotating motor can adjust the opening and closing between the two second baffles.
[0010] Preferably, a pressure sensor is provided on the lower outer wall of the third rotating motor, and a controller is fixedly connected to one side of the outer wall of the second housing. The controller is connected to the pressure sensor and the rotating motor through a circuit.
[0011] Preferably, a feed inlet is fixedly connected to the upper outer wall of the first housing. The feed inlet is used for feeding, and the raw material first falls onto the second grinding roller.
[0012] Compared with existing technologies, the advantages of this utility model are: This invention utilizes a main gear meshing with first and second driven gears of different pitch circle radii to generate differentiated speed outputs. This, combined with a high-speed first grinding roller and a low-speed second grinding roller connected in a one-to-one correspondence with the gears, constructs a scientifically designed graded crushing structure. The raw material is first initially crushed by the low-speed second grinding roller, and then finely sheared by the high-speed first grinding roller. This step-by-step crushing, achieved through the speed difference, effectively solves the problems of uneven crushing and inconsistent particle size inherent in traditional single-speed crushing equipment, significantly improving the uniformity and fineness of the crushed raw material.
[0013] Based on the first beneficial effect, this utility model, with its dual baffle structure and automated linkage design of pressure sensor and controller, allows the crushed raw materials to fall directly into the second shell for temporary storage. The pressure sensor detects the weight in real time and provides feedback signals, while the controller automatically adjusts the opening and closing of the baffles according to a preset threshold. This achieves integrated continuous operation of raw material crushing, weighing, and unloading without the need for manual intervention. It completely avoids the tedious operations and errors caused by manual transfer and weighing in traditional split-type equipment, significantly improving overall operating efficiency and weighing accuracy.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example
[0021] Please see Figures 1-4 As shown, this embodiment is an automatic raw material crushing and weighing device, including a first housing 2, a cover 13, and a first rotating motor 6. The cover 13 is provided on one outer wall of the first housing 2, and the first rotating motor 6 is fixedly connected to the outer wall of one side of the cover 13. The output shaft of the first rotating motor 6 is fixedly connected to the outer wall of one side of the main gear 7. Two second driven gears 8 and three first driven gears 5 are provided on one outer wall of the first housing 2. The main gear 7 meshes with one of the first driven gears 5 and the second driven gear 8 respectively. Adjacent first driven gears 5 mesh with each other, and second driven gears 8 mesh with each other. The radius of the second driven gear 8 is larger than the radius of the first driven gear 5. In use, starting the first rotating motor 6 can drive the main gear 7 to rotate synchronously, thereby driving all the first driven gears 5 and the second driven gears 8 to rotate simultaneously through the gear meshing relationship. Because the radius of the second driven gear 8 is larger, its rotation speed is less than that of the first driven gear 5, forming a differentiated speed output. Example
[0022] Please see Figures 1-4 As shown, this embodiment further includes, based on embodiment 1, a plurality of first grinding rollers 9 and second grinding rollers 10 are provided inside the first housing 2. One end of the first grinding roller 9 is connected to the corresponding first driven gear 5, and the second grinding roller 10 is connected to the corresponding second driven gear 8. In use, the rotation of the first driven gear 5 can drive the corresponding first grinding roller 9 to rotate synchronously at high speed, and the rotation of the second driven gear 8 can drive the corresponding second grinding roller 10 to rotate synchronously at low speed. The raw materials are graded and crushed by the cooperation of the fast and slow grinding rollers.
[0023] A mounting plate 3 is fixedly connected to the lower outer wall of the first housing 2. A second housing 18 is provided on the lower outer wall of the mounting plate 3. A discharge port 4 is provided on the lower outer wall of the second housing 18. During use, the crushed raw material in the first housing 2 can fall into the lower second housing 18 for temporary storage by its own gravity. After weighing is completed, the material is discharged quantitatively from the discharge port 4.
[0024] Two sets of symmetrical second rotary motors 14 and third rotary motors 15 are provided on one outer wall of the second housing 18. The output shaft of the second rotary motor 14 is fixedly connected to one end of the corresponding first baffle 11, and the output shaft of the third rotary motor 15 is fixedly connected to one end of the corresponding second baffle 12. In use, driving the second rotary motor 14 can drive the corresponding first baffle 11 to rotate around the output shaft, thereby adjusting the opening angle and opening degree between the two relatively set first baffles 11. The opening and closing of the first baffle 11 is used to control the amount of raw material entering the second housing 18. Driving the third rotary motor 15 can drive the corresponding second baffle 12 to rotate around the output shaft, realizing the opening and closing regulation between the two relatively set second baffles 12. The double baffles can improve the accuracy of unloading control.
[0025] A pressure sensor 16 is provided on the lower outer wall of the third rotating motor 15, and a controller 17 is fixedly connected to one side outer wall of the second housing 18. In use, the pressure sensor 16 can detect the weight of the raw material temporarily stored above the second baffle 12 inside the second housing 18 in real time (the pressure sensor 16 is installed at the lower end of the output shaft of the third rotating motor 15, and the weight of the second baffle 12 and the material above it will be sensed by the pressure sensor 16 and the pressure value will be displayed). The weight detection signal is converted into an electrical signal and transmitted to the controller 17. The controller 17 automatically controls the start and stop of the second rotating motor 14 and the third rotating motor 15 through a preset weight threshold, thereby realizing the automatic control of the opening and closing of the baffle.
[0026] The upper outer wall of the first housing 2 is fixedly connected to the feed inlet 1. During use, the raw material to be crushed is accurately fed into the first housing 2 through the feed inlet 1, and the path of the raw material falling is directly above the second grinding roller 10, ensuring that the raw material first contacts the second grinding roller 10 rotating at low speed, and starts the grading crushing process.
[0027] Instructions for use: When using this device, the raw material to be processed is first fed into the funnel-shaped feed inlet 1 at the upper end of the first housing 2. The raw material falls through an inclined channel onto the second grinding roller 10. The first rotating motor 6 is started, and the main gear 7 drives the first and second driven gears 8 of different radii to rotate synchronously, driving the corresponding grinding rollers to achieve high-speed and low-speed graded crushing. The raw material is first initially crushed by the low-speed grinding roller, and then finely processed by the high-speed grinding roller. After crushing, the raw material falls into the second housing 18. The pressure sensor 16 detects the weight in real time and transmits a signal to the controller 17. When the weight reaches a preset threshold, the controller 17 automatically closes the first baffle 11 to stop feeding, and simultaneously opens the second baffle 12, allowing the raw material to be quantitatively discharged from the outlet 4. After unloading, the controller 17 adjusts the baffle to reset, allowing the next round of operation to begin. The entire process requires no manual intervention, is suitable for continuous production, and is convenient, efficient, and precise in operation.
