Description

Technical Field

[0001] This utility model belongs to the field of safflower shear force detection technology, and in particular relates to a safflower shear force testing platform. Background Technology

[0002] Safflower is an annual herb, also known as safflower, red safflower, or thorny safflower. It belongs to the Asteraceae family and the Safflower genus. The dried tubular flowers are orange-red, with narrow, linear lobes at the tip. The anthers are yellow, fused into a tube extending beyond the lobes, with a stigma protruding from the center. It has a distinctive aroma and a slightly bitter taste. The best quality safflower has long, bright red petals and a soft texture. After the safflower matures, the safflower threads need to be cut off. After further processing, the safflower threads can be used as a traditional Chinese medicine. Safflower threads have analgesic, wind-dispelling, blood-activating, and swelling-reducing effects. Currently, the cutting of safflower threads is done manually by cutting... Harvesting safflower filaments manually using a knife is inefficient and labor-intensive. Therefore, a more efficient mechanical safflower filament shearing device needs to be developed. However, before developing such a device, it is necessary to determine the required shearing force to cut the safflower filaments. This would allow for more accurate selection of the power mechanism during device production, saving costs. However, existing technologies lack suitable devices to detect the shearing force required to cut safflower filaments, making it inconvenient to test and collect data on the magnitude of the shearing force. Utility Model Content

[0003] To address the technical problem of inconvenient data acquisition of safflower shear force in existing systems, this invention provides a safflower shear force testing platform. The platform includes a horizontally positioned support base with several supporting legs at its base. A switching power transformer, an air switch, and a PLC controller are detachably fixed to the top of the support base, and these components are electrically connected via cables. The platform also includes a vertically positioned electromagnet mounting bracket, detachably fixed to the top of the support base. A push-pull electromagnet is detachably fixed to the bracket, with a return spring at one end of a movable rod and a pressure sensor at the other end. The pressure sensor collects data on the pressure required to shear the safflower filaments. A blade mounting bracket is fixed to the end of the pressure sensor, and a horizontally positioned shearing blade is detachably fixed to the bracket. When the push-pull electromagnet is energized, the movable rod pushes the shearing blade towards the cylinder to shear the safflower filaments. It also includes a vertically arranged cylinder, the bottom of which is detachably fixed to the top of the support platform. A vertically arranged feed inlet is located at the top of the cylinder, and a slot for the shearing blades to pass through is located on one side of the cylinder. The safflower is placed upside down. It also includes a PC signal collection terminal, and the pressure sensor, PLC controller, and PC signal collection terminal are connected by cables. A serial port is also included for connection; one end of the serial port is connected to the PLC controller, and the other end is connected to the PC signal collection terminal. After the push-pull electromagnet is activated, the movable slide rod pushes the shearing blades to detect and process the safflower filaments inside the cylinder. The pressure sensor transmits the detected shearing force data to the PC signal collection terminal, which analyzes and processes the collected pressure signal data to determine the range of safflower shearing force. Based on the magnitude of the shearing force, an appropriate power mechanism is selected during the design and production of the safflower filament shearing device.

[0004] Preferably, the shearing blade has a vertically arranged discharge hole.

[0005] Preferably, the diameter of the material discharge hole is larger than the diameter of the safflower flower.

[0006] Preferably, the diameter of the feed inlet is larger than the diameter of the safflower flower.

[0007] Preferably, the bottom end of the cylinder is provided with a cylinder fixing frame, which can be detachably fixed to the support platform.

[0008] The above scheme has the following advantages: The push-pull electromagnet controls the position of the shearing blade by controlling its start and stop, thus cutting the safflower filaments and improving efficiency. The pressure sensor collects the magnitude of the shearing force on the safflower filaments. Based on this range of shearing force, the power of the drive motor and the model of the cylinder in the subsequent design and production of the safflower shearing device can be easily selected, saving production costs and improving efficiency. The PC signal acquisition terminal can analyze and process the shearing force data collected by the pressure sensor, providing multi-data analysis of the safflower filament shearing force range.

[0011] like Figure 1-2As shown, a safflower shear force testing platform includes a horizontally arranged support platform 1, which serves as a support. The bottom of the support platform 1 is provided with several support legs. The top of the support platform 1 is detachably fixed with a switching power transformer 11, an air switch 12, and a PLC controller 13. The switching power transformer 11, the air switch 12, and the PLC controller 13 are electrically connected through a cable 4. It also includes a vertically arranged electromagnet mounting bracket 21, which is detachably fixed to the top of the support platform 1. A push-pull electromagnet 2 is detachably fixed on the electromagnet mounting bracket 21. One end of the movable slide rod 23 on the push-pull electromagnet 2 is provided with a return spring 22. The other end of the movable slide rod 23 on the push-pull electromagnet 2 is fixed with a pressure sensor 24. The pressure sensor 24 can collect the pressure data of cutting safflower filaments. A blade mounting bracket 25 is fixed to the end of the pressure sensor 24. A horizontally arranged shearing blade 26 is detachably fixed on the blade mounting bracket 25. After the push-pull electromagnet 2 is energized, the movable slide rod 23 pushes the shearing blade 26 toward the cylinder 3 and cuts the safflower filaments. It also includes a vertically arranged cylinder 3, the bottom of which is detachably fixed to the top of the support platform 1. The top of the cylinder 3 has a vertically arranged feed port 32, and one side of the cylinder 3 has a slot 33 for the shearing blade 26 to pass through. The safflower is placed upside down. It also includes a PC signal collection terminal 14, and the pressure sensor 24, the PLC controller 13 and the PC signal collection terminal 14 are connected by a cable 4. It also includes a serial port 15 for connection. One end of the serial port 15 is connected to the PLC controller 13, and the other end of the serial port 15 is connected to the PC signal collection terminal 14. After the push-pull electromagnet 2 is activated, the movable slide rod 23 pushes the shearing blade 26 to detect and process the safflower filaments in the cylinder 3. The pressure sensor 24 transmits the detected shearing force data to the PC signal collection terminal 14. The PC signal collection terminal 14 analyzes and processes the collected pressure signal data, and finally determines the magnitude range of the safflower shearing force. According to the magnitude of the shearing force, an appropriate power mechanism is selected when designing and producing the safflower filament shearing device.

[0012] Preferably, the shearing blade 26 has a vertically arranged discharge hole 261.

[0013] Preferably, the diameter of the material discharge hole 261 is larger than the diameter of the red flower.

[0014] Preferably, the diameter of the feed inlet 32 ​​is larger than the diameter of the safflower flower.

[0015] Preferably, the bottom end of the cylinder 3 is provided with a cylinder fixing frame 31, which can be detachably fixed on the support platform 1.

[0016] Usage process: In use, a bunch of safflower filaments to be tested are taken and placed downwards through the feed inlet 32 ​​into the cylinder 3. After the safflower filaments have moved to the appropriate position, the push-pull electromagnet 2 is activated. The movable slide rod 23 on the push-pull electromagnet 2 pushes the shearing blade 26 to shear the safflower filaments. At this time, the pressure sensor 24 will collect the pressure required to shear the safflower filaments. The maximum pressure value is taken as the maximum force required to shear the safflower filaments. Then, the safflower filaments of the selected samples are sheared one by one. The pressure sensor 24 transmits the collected shearing force signal to the PC signal collection terminal 14. After data analysis, the range of the required shearing force of the safflower filaments is selected, which facilitates the selection of an appropriate power mechanism when designing and manufacturing the safflower filament shearing device.
