Description

Technical Field

[0001] This invention belongs to the technical field of grain processing equipment, and mainly relates to a grain processing scraping strength detection and material collection device. Background Technology

[0002] In the grain milling process, peeling strength testing is of great value for improving the economic benefits of grain flour production, such as quality control, energy consumption reduction, and increased flour yield. However, peeling strength testing is time-consuming, labor-intensive, and requires a high level of technical skill and responsibility from the technicians.

[0003] Testing with traditional scraping rate sieves requires more manpower and labor intensity. Therefore, most flour milling companies know the benefits of testing the scraping rate in flour milling, but they can only sigh in vain because they cannot provide a set of high-efficiency scraping strength testing equipment and understand the impact of the test data on production control.

[0004] Peel strength testers are used in most large-scale grain milling enterprises in China. However, due to factors such as the long process of collecting flour and waiting for testing, a large number of technical personnel are required, and the labor intensity is high. Operation requires manual input of individual samples, consuming significant time. For large-scale testing, operators must wait for extended periods in front of the equipment to feed samples, thus preventing milling enterprises from fully utilizing its value. Current technology lacks a sample collection and feeding device specifically designed for peel strength testing. Summary of the Invention

[0018] This invention relates to a grain processing peeling strength testing collection and collection device.

This invention significantly reduces manual labor intensity, eliminates operational errors such as manual sampling, misplacement of samples, and mixed or missed samples, ensuring uniform sample collection status, standardized timing, and stable and even sampling, effectively improving the accuracy, repeatability, and validity of peeling strength testing data. The device has a compact structure, smooth transmission, high degree of automation, and good operational stability, making it suitable for continuous operation scenarios of batch grain testing. It effectively improves overall testing efficiency and quality, reduces equipment maintenance costs, and has good practical value and prospects for widespread application. By setting up a bottom pallet conveying mechanism, a top pallet conveying mechanism, a pallet lifting mechanism, and a pallet body, materials can be collected and retrieved freely and flexibly as needed, achieving continuity in the sample collection process.

[0033] Example 1, see Figure 1-9 :

[0034] A grain processing scraping strength testing and material collection device includes a frame body 1, a bottom pallet conveying mechanism 2, a top pallet conveying mechanism 3, and a pallet lifting mechanism 4. (See also...) Figure 5 The frame body 1 is a frame structure. The bottom pallet conveying mechanism 2 is located at the bottom of the frame body 1, the top pallet conveying mechanism 3 is located at the top of the frame body 1, and the pallet lifting mechanism 4 is located in the frame body 1.

[0035] The overall structure of the grain processing peeling strength testing collection and handling device consists of two rows of pallet frames (controlled by a pallet lifting mechanism 4). The pallet body 5 is supported by the pallet frames on both sides, and each row includes multiple pallet support frames. Sample boxes are placed on the pallet body 5. During loading / unloading, the pallet body 5 with sample boxes can be placed on top, or the pallet body 5 without sample boxes can be placed after testing. During testing, the top pallet conveying mechanism 3 lifts the entire pallet body 5 to ensure the accuracy of the sampling position of each sample box on different pallet bodies 5. An external robotic arm removes each sample box from the pallet body 5 one by one and pours it into an external peeling rate detector for testing. After each sample box on the pallet body 5 has been tested, the pallet body 5 is transferred to an empty pallet frame in another row. Then, the pallet lifting mechanism 4 lowers the entire pallet body 5 and pallet support frames, while the pallet body 5 in the other row rises along with the pallet frame, allowing a new pallet body 5 with untested sample boxes to rise to the testing position. When pallet body 5 stops moving to the bottom, the bottom pallet conveyor 2 transfers pallet body 5 to another row of pallet racks. Loading / unloading also follows this process, except the stopping and waiting inspection step is omitted.

[0036] See Figure 6The bottom pallet conveying mechanism 2 includes a bottom conveying support plate 201, a bottom transmission module, and a bottom pallet carrier 207. The bottom transmission module is mounted on the bottom conveying support plate 201, and the bottom pallet carrier 207 slides on the bottom transmission module. The bottom transmission module includes a bottom drive device 203, a bottom drive module, and a bottom driven module. The bottom drive module and the bottom driven module are arranged side by side on the upper surface of the bottom conveying support plate 201. The bottom drive device 203 is connected to the bottom drive module, and the bottom drive module and the bottom driven module are connected by a bottom transmission belt 209. The bottom pallet carrier 207 slides synchronously on the bottom drive module and the bottom driven module.

[0037] The bottom drive module includes a bottom drive side support plate 202, a bottom drive side support base 204, a bottom drive side lead screw 205, a bottom drive side slider 206, and a bottom drive wheel 208. The bottom drive side support plate 202 is located on the upper surface of the bottom conveyor support plate 201, and the bottom drive side support base 204 is located on the upper surface of the bottom drive side support plate 202. The bottom drive side lead screw 205 is rotatably mounted in the bottom drive side support base 204 along the length of the bottom drive side support plate 202. One end of the bottom drive side lead screw 205 is connected to the bottom drive device 203, and the other end is connected to the bottom drive wheel 208. The bottom drive side slider 206 is slidably mounted on the bottom drive side lead screw 205, and the bottom tray carrier 207 is located on the upper end of the bottom drive side slider 206.

[0038] The bottom driven module includes a bottom driven wheel 210, a bottom driven side support plate 211, a bottom driven side support base 212, a bottom driven side lead screw 213, and a bottom driven side slider 214. The bottom driven side support plate 211 is located on the upper surface of the bottom conveyor support plate 201, and the bottom driven side support base 212 is located on the upper surface of the bottom driven side support plate 211. The bottom driven side lead screw 213 is rotatably mounted in the bottom driven side support base 212 along the length of the bottom driven side support plate 211. One end of the bottom driven side lead screw 213 is connected to the bottom driven wheel 210. The bottom driven wheel 210 is rotatably connected to the bottom drive wheel 208 via a bottom transmission belt 209. The bottom driven side slider 214 is slidably mounted on the bottom driven side lead screw 213, and the bottom tray carrier 207 is located at the upper end of the bottom driven side slider 214. The bottom end of the bottom tray carrier 207 on the bottom drive side slider 206 is provided with a bottom drive side cylinder 215 and a bottom driven side cylinder 216, and the bottom driven side slider 214 on the bottom tray carrier 207 is provided with a bottom driven side cylinder 216.

[0039] See Figure 6 The specific working principle of the bottom pallet conveying mechanism 2:

[0040] The rotation of the bottom drive device 203 drives the rotation of the bottom drive-side lead screw 205. The rotation of the bottom drive-side lead screw 205 causes the bottom drive-side slider 206 to move along the length of the lead screw 205, simultaneously driving the bottom drive wheel 208 to rotate. The bottom drive wheel 208 drives the bottom driven wheel 210 to rotate synchronously via the bottom transmission belt 209. The bottom driven wheel 210 drives the bottom driven-side lead screw 213 to rotate, and the rotation of the bottom driven-side lead screw 213 causes the bottom driven-side slider 214 to move along the length of the lead screw 213. The bottom tray carrier 207, connected to the bottom drive-side slider 206 and the bottom driven-side slider 214, moves. The bottom tray carrier 207 is driven to rise and move by the bottom drive-side cylinder 215 and the bottom driven-side cylinder 216.

[0041] The bottom pallet conveying mechanism 2 lifts the pallet body 5 on the lowest pallet rack in a row, moves it to the position of the pallet rack in another row, and places it down.

[0042] Operation process: In the non-detection row position, after all other corresponding movements are completed, the bottom drive side cylinder 215 and the bottom driven side cylinder 216 lift the drive unit tray carrier 207, raising the tray body 5 to a certain position to avoid spatial interference from the tray frame. After the proximity switches on the bottom drive side cylinder 215 and the bottom driven side cylinder 216 confirm that the tray body 5 has been lifted, the bottom drive device 203 (motor) drives the bottom tray carrier 207 to move towards the tray frame position of the detection row.

[0043] When the bottom pallet carrier 207 reaches the correct position on one side of the detection row, the movement stops, and the bottom drive cylinder 215 and the bottom driven cylinder 216 lower the pallet body 5, placing it on the pallet rack. After confirming the pallet rack is in place by the proximity switch, the mechanism immediately begins to move to a non-detection row position. Once it reaches the appropriate position, the movement of the bottom drive device 203 (motor) stops, and the entire bottom pallet conveying mechanism 2 completes normal operation.

[0044] Upon startup, to ensure the correct position of the bottom tray conveyor 2 at all times, a movement process towards the origin is required for confirmation. When the tray frame is sensed at the origin position, it first moves a certain distance towards the detection line, and after completing this movement, it moves back to the origin. After being sensed at the origin, it moves for the same amount of time and then stops immediately.

[0045] See Figure 7The top pallet conveying mechanism 3 includes a top drive module and a top driven module, which are respectively connected to the upper end of the frame body 1. The top drive module is connected to a top drive device 303. The top drive module is slidably connected to a top driven side gripper 316, and the top driven module is slidably connected to a top driven side gripper. The top drive module and the top driven module rotate synchronously via a top transmission belt 309, and the top driven side gripper 316 and the top driven side gripper move synchronously.

[0046] The top drive module includes a top drive side mounting plate 301, a top drive side support plate 302, a top drive side support base 304, a top drive side lead screw 305, a top drive side slider 306, and a top drive wheel 308. The top drive side mounting plate 301 is connected to the top of the frame body 1. The top drive side support plate 302 is located at the lower end of the top drive side mounting plate 301. The top driven side support base 313 is located at the lower end of the top drive side support plate 302. The top drive side lead screw 305 is slidably mounted in the top drive side support base 304. One end of the top drive side lead screw 305 is connected to the top drive device 303, and the other end is connected to the top drive wheel 308. The top drive side slider 306 is slidably mounted on the top drive side lead screw 305, and the top drive side gripper 307 is connected to the top drive side slider 306.

[0047] The top driven module includes a top driven side mounting plate 311, a top driven side support plate 312, a top driven side support base, a top driven side lead screw, a top driven side slider, and a top driven wheel 310. The top driven side mounting plate 311 is connected to the top of the frame body 1. The top driven side support plate 312 is located at the lower end of the top driven side mounting plate 311, and the top driven side support base is located at the lower end of the top driven side support plate 312. The top driven side lead screw is slidably mounted in the top driven side support base, and one end of the top driven side lead screw is connected to the top driven wheel 310. The top driven wheel 310 is connected to the top drive wheel 308 via a top transmission belt 309. The top driven side slider is slidably mounted on the top driven side lead screw, and the top driven side gripper is connected to the top driven side slider. A top drive side cylinder 317 and a top driven side cylinder 318 are provided on one side of the top drive side slider 306, and a top driven side cylinder 318 is provided on one side of the top driven side slider 315.

[0048] See Figure 7 The specific working principle of the top tray conveying mechanism 3:

[0049] The rotation of the top drive device 303 drives the top drive side screw 305 to rotate. The rotation of the top drive side screw 305 drives the top drive side slider 306 to move along the length direction of the top drive side screw 305. The top drive side gripper 307 connected to the top drive side slider 306 moves synchronously. The top drive side screw 305 simultaneously drives the top drive wheel 308 to rotate. The top drive wheel 308 drives the top driven wheel 310 to rotate synchronously through the top transmission belt 309. The top driven wheel 310 drives the top driven side screw 314 to rotate. The top driven side screw 314 drives the top driven side slider 315 to move along the length direction of the top driven side screw 314. The top driven side gripper 316 connected to the top driven side slider 315 moves synchronously. The top drive side cylinder 317 drives the top drive side gripper 307, and the top driven side cylinder 318 drives the top driven side gripper 316 to perform the lifting action.

[0050] The top pallet conveying mechanism 3 will lift the pallet body 5 on the pallet rack at the highest position in the detection row, move it to the pallet rack position in another row, and place it down.

[0051] Operation process: In the non-detection row position, after all other corresponding movements are completed, the cylinder moves to the downward position of the detection row and lowers the top drive side cylinder 317 and the top driven side cylinder 318, moving from the internal gap of the tray body 5 to the tray position correction position. The tray is raised, and if in detection mode, waits for the external sampling robot (not shown in the figure) and the peeling rate detector to sample and detect one by one. When the detection mode is completed or other operating modes are entered, after the proximity switches on the top drive side cylinder 317 and the top driven side cylinder 318 confirm that the tray body 5 has been lifted, the top drive device 303 (motor) begins to move through the lead screw slide to the non-detection row tray frame position, and lowers the top drive side cylinder 317 and the top driven side cylinder 318, lowering the tray body 5 onto the non-detection row tray frame. After moving a certain distance, it reaches the cylinder up and down space, raising the top drive side cylinder 317 and the top driven side cylinder 318. At this point, a complete movement cycle is completed. When the proximity switch detects the arrival of the pallet support frame at the correct position on one side of the detection row, it stops moving and lowers the pallet body 5 by means of the top drive-side cylinder 317 and the top driven-side cylinder 318, placing the pallet body 5 on the pallet frame. After confirming the pallet frame is in place by the proximity switches on the top drive-side cylinder 317 and the top driven-side cylinder 318, it immediately begins to move to the non-detection row position. After reaching the appropriate position, the motor stops moving, and the entire top pallet conveying mechanism 3 completes normal operation.

[0052] Upon startup, to ensure the correct position of the top tray conveyor 3 at all times, a movement process towards the origin is required for confirmation. When the tray frame is sensed at the origin position, it first moves a certain distance towards the detection line, and after completing this movement, it moves back to the origin. After being sensed at the origin, it moves for the same amount of time and then stops immediately.

The middle bottom drive wheel 409 and the middle top driven wheel 411 are connected by the middle transmission chain 410. A middle pallet frame 414 is provided on the side transmission chain 403. The middle pallet frame 414 and the adjacent side pallet frames 407 form a pallet frame that supports the pallet body 5.

[0054] The lifting mechanism side modules are arranged in pairs, facing each other. The lower ends of the two side modules are connected by a side bottom rotation shaft 405 that passes through the corresponding side bottom drive wheel 402, and the upper ends are connected by a side top rotation shaft 406 that passes through the corresponding side top driven wheel 404.

[0055] See Figure 8 The specific working method of pallet lifting mechanism 4:

[0056] The drive unit (not shown in the figure) drives the side bottom drive wheel 402 and the middle bottom drive wheel 409 to rotate synchronously. The side bottom drive wheel 402 drives the side top driven wheel 404 to rotate synchronously via the side transmission chain 403. The middle bottom drive wheel 409 drives the middle top driven wheel 411 to rotate synchronously via the middle transmission chain 410. The side pallet frame 407 connected to the side transmission chain 403 and the middle pallet frame 414 connected to the middle transmission chain 410 move synchronously.

[0057] Tray body 5 (see Figure 9 The container 5 is used to hold the test sample boxes and is placed on a tray rack. It is hollow and can accommodate the sample boxes. In this embodiment, the grain processing peeling strength test collection and picking device has 12 tray bodies 5, each tray body 5 can hold 18 test sample boxes, for a total of 216. After collecting the material once a day, a medium or larger flour mill can conduct continuous testing.

[0058] See Figure 2 The pallet lifting mechanism 4 is responsible for transferring the pallet body 5 to the appropriate position through lifting and lowering. The pallet frame is divided into two columns: one for detection and one for inspection. The detection column continuously rises from the bottom to the top, while the inspection column descends from the top to the bottom. Each movement raises and lowers one pallet position, driven by three stepper motors with reduction gears. These motors move synchronously under the same motion drive. The three stepper motors share the same pulse signal to achieve complete synchronization of speed and step distance. By reversing the phase sequence of the winding connections, two sets of motors rotate forward and one set rotates in reverse. The stepper motors are appropriately wired to ensure that, under the same control source, the motors move in the same direction: one column moves upward and the other downward.

[0059] Movement process: Upon startup, the top tray conveyor 3 (see...) Figure 7 The top drive-side cylinder 317 and the top driven-side cylinder 318 rise, driving the top drive-side gripper 307 and the top driven-side gripper 316 to move upward and lift the top tray. The bottom tray conveying mechanism 2 (see...) Figure 6 The bottom drive cylinder 215 and the bottom driven cylinder 216 lift up the bottom tray carrier 207 to lift the bottom tray. The top and bottom tray conveying mechanisms operate simultaneously, transferring the top and bottom tray bodies 5 to their respective positions. Then, the tray lifting mechanism 4 starts to operate. The detection column sinks from the top to the bottom and rises from the bottom to the top. After sensing the proximity switch, it slows down and moves for a certain period of time to enter the designated position before stopping.

[0060] This invention relates to a grain processing peeling strength testing collection and collection device. Through a three-dimensional pallet arrangement structure, it significantly improves space utilization and effectively increases single-sampling capacity, meeting the needs of continuous, uninterrupted testing in a single shift. The invention features a bottom pallet conveying mechanism, a top pallet conveying mechanism, and a pallet lifting mechanism working together to achieve a continuous operation process of automatic pallet replenishment, temporary collection, precise collection, and automatic conveying. The collection and collection modes can be flexibly switched according to the testing process, overcoming the shortcomings of traditional equipment such as dispersed processes, excessive manual intervention, and inability to operate continuously. This invention significantly reduces manual labor intensity, eliminates operational errors such as manual sampling, misplacement of samples, and mixed or missed samples, ensuring uniform sample collection status, standardized timing, and stable and even sampling, effectively improving the accuracy, repeatability, and validity of peeling strength testing data. The device has a compact structure, smooth transmission, high degree of automation, and good operational stability, making it suitable for continuous operation scenarios of batch grain testing. It effectively improves overall testing efficiency and quality, reduces equipment maintenance costs, and has good practical value and prospects for widespread application. By setting up a bottom pallet conveying mechanism, a top pallet conveying mechanism, a pallet lifting mechanism, and a pallet body, materials can be collected and retrieved freely and flexibly as needed, achieving continuity in the sample collection process. This greatly reduces the labor intensity and error rate of personnel involved in the peel strength testing, and significantly improves the effectiveness of the information provided by the peel strength testing equipment.

[0061] This invention enables the automatic testing of 216 samples in a single round. After manual loading of the samples within a short time, the testing system can be started without requiring personnel to wait on-site for material feeding. This solves the problem of grinding strength testers being unable to continuously perform automatic testing, improving the real-time performance of sample testing results during production.

[0062] The grain processing peeling strength testing material collection and collection device of the present invention, by setting up a bottom tray conveying mechanism, a top tray conveying mechanism, a tray lifting mechanism and a tray body, can collect and collect materials freely and flexibly as needed, realize the continuity of the sample collection process, greatly reduce the labor intensity and error rate of peeling rate testing personnel, and greatly improve the effectiveness of the peeling strength testing equipment in providing peeling strength information. In the fiercely competitive flour production market, it can greatly enhance the competitiveness of enterprises.

[0063] Example 2 is an improvement on Example 1. The similarities will not be repeated here; the differences are as follows:

[0064] This invention also includes a control system, which is centered on an industrial main control unit, and consists of sensors, drive modules, and a human-machine interface touchscreen (the grinding strength tester also functions as an industrial control computer). The control system is divided into four main parts: signal acquisition, logic operation, execution drive, and human-machine interaction. Sensors detect parameters such as position and speed in real time and transmit them to the main control system; the program automatically issues commands to drive motors, cylinders, and other actuators to complete the entire process according to preset process logic. The equipment supports both fully automatic operation and manual single-point debugging modes to meet different needs for production debugging and normal operation. The system has built-in intelligent fault diagnosis, overload protection, and emergency shutdown safety mechanisms, automatically alarming and shutting down in case of abnormalities. This facilitates management and truly achieves fully automated and intelligent control of the entire process.

[0065] The grain processing scraping strength detection collection and extraction device of this application can be a supporting device for an authorized patented automatic scraping rate testing device in flour processing (patent number: ZL201910424584.8).

[0066] The entire system operates as follows (including the robotic arm and grinding strength tester): After system startup, the industrial control host computer instructs the intelligent material storage bin to move the material tray to the testing station. The robotic arm then moves to grasp the sample box for information recognition. Once the sample box information matches the stored grinding joint information, the robotic arm guides the material into the equipment's testing port. The material information is then reconfirmed, and any used information on the material box is cleared. Simultaneously, the grinding strength tester is started. After the grinding strength tester finishes its operation, the robotic arm returns the material box to its original position and waits. After the grinding strength tester completes its operation, the host computer updates and displays the test results and synchronizes them to the production system.

[0067] The embodiments described above are merely preferred embodiments of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope defined by the claims of the present invention.
