Description

Technical Field

[0001] This invention belongs to the field of silk processing technology, and specifically relates to an automatic boiling device for mechanical testing of degummed silk. Background Technology

[0002] According to Chinese standards, the traditional degumming process for silk requires handling and washing to remove the sericin through methods such as hand rubbing, squeezing, and scraping. First, the repeated hand rubbing during degumming alters the original physical form of the silk, causing it to eventually clump together, directly affecting the measurement of the mechanical properties of the degummed silk. Second, the degumming rate obtained by traditional methods is not necessarily accurate, with relatively large errors, and cannot perfectly determine whether degumming is complete.

[0003] Therefore, developing a device that can maintain the physical morphology of silk during degumming while improving degumming efficiency and accuracy is crucial for testing the mechanical properties of degummed silk and for automating the testing process. Accurate and efficient degumming testing is of great significance for promoting fair trade in silk and the sustainable development of the industry. Summary of the Invention

[0004] To address the shortcomings of the prior art, this invention provides an automatic boiling and rinsing device for mechanical testing of degummed silk.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic scouring device for mechanical testing of degummed silk includes a device body, an electric rotating platform, a degumming column, a winding mechanism, an electrically controlled moving brush device, a heating and temperature control device, a pure water inlet, a degumming agent solution inlet, a conductivity sensor, and a controller. The electric rotating platform, heating and temperature control device, and conductivity sensor are internally housed within the device body. The degumming column is detachably and vertically mounted on the electric rotating platform. Several winding mechanisms are detachably mounted vertically on the degumming column. Electrically controlled moving brush devices are located on the left and right sides of the degumming column. The pure water inlet and the degumming agent solution inlet are located at the top of the device body. The controller is located on the front of the device body.

[0006] The scouring device of the present invention enables the silk to complete the entire degumming process by brushing in a water bath, thereby improving the degumming efficiency and uniformity. It also maintains the physical morphology of the silk during the degumming process, which is convenient for subsequent mechanical property testing. The conductivity sensor and controller are used to monitor the pH of the degumming solution and the degree of degumming completion.

[0007] Furthermore, the device body includes a base, a housing, a main top cover, a secondary top cover, and a latch. A rectangular housing is provided on the base; the main top cover is fixedly provided on the top of the housing, and the secondary top cover is provided in the center of the main top cover through the latch. The base, housing, and main top cover form an inner cavity for boiling and smelting silk.

[0008] Furthermore, it also includes a cross-shaped connecting column and a rotating disk. The cross-shaped connecting column is fixedly installed on the electric rotating platform. The bottom of the degumming column is inserted into the cross-shaped connecting column. The insertion connection of the cross-shaped connecting column allows for easy disassembly and assembly of the degumming column and also ensures that the degumming column can rotate with the electric rotating platform after installation. The rotating disk is rotatably installed on the top of the degumming column. The rotating disk is in contact with the bottom of the sub-top cover. The function of the rotating disk is to ensure that the 360° rotation of the degumming column is not affected after the top of the degumming column is fixed.

[0009] Furthermore, the electrically controlled movable brush device includes a brush, a limiting slide rod, an electric telescopic rod, and a drive rod. The limiting slide rod is fixedly installed on the inner side of the housing, and the brush is slidably connected to the limiting slide rod. The electric telescopic rod is fixedly installed behind the brush. One end of the drive rod is hinged to the top of the electric telescopic rod, and the other end of the drive rod is hinged to the back of the brush. Under the driving action of the electric telescopic rod and the drive rod, the brush can move back and forth in a straight line along the limiting slide rod, thus moving closer to or further away from the degumming column. With the help of the rotation of the degumming column, the silk on the degumming column is brushed.

[0010] Furthermore, the winding mechanism includes a ring, connecting rods, a U-shaped fork, and a movable lock. The ring is provided with a movable lock that is movably connected to the degumming column. Six connecting rods are evenly arranged on the side of the ring. The U-shaped fork is fixedly arranged outward at the front end of the connecting rod. One of the six connecting rods is a spring telescopic rod. The movable arrangement of the winding mechanism facilitates the loading and unloading of silk.

[0011] Furthermore, it also includes a draining device, which is located on the left side of the base. The draining device includes a drain outlet, a drain pipe, and an electric valve. The drain outlet is located on the top left side of the base, and the drain pipe is located on the left side of the base, communicating with the drain outlet. An electric valve is installed on the drain pipe. The draining device is mainly used to automatically drain the liquid inside the scouring device after the silk degumming is completed.

[0012] Furthermore, the controller is equipped with a control panel, which includes a power switch, a setting button, an up button, a down button, a de-adhesion button, a return button, and a display screen.

[0013] Furthermore, the controller is equipped with a heating and temperature control system, an automated degumming system, a conductivity detection system, a liquid inlet and drainage system, and a forced stop system. The heating and temperature control system, the automated degumming system, the conductivity detection system, the liquid inlet and drainage system, and the forced stop system are software control programs.

[0014] Furthermore, it also includes an emergency stop button, which is located on the right side of the device body. The emergency stop button can forcibly stop the operation of the control system in order to deal with emergencies.

[0015] Furthermore, during the degumming operation, the mass ratio of silk to the scouring liquid in the scouring device is 1:200. According to relevant research, the degumming effect is relatively best when the bath ratio is 1:200.

[0016] Furthermore, it also includes an observation window, which is provided on the front of the device body to facilitate observation of the silk refining process.

[0017] The advantages of this invention are as follows: 1. With the cooperation of an electric rotating platform, a degumming column, a winding mechanism, an electrically controlled moving brush device, and a heating and temperature control device, the scouring device of this invention can automatically complete the normal degumming of silk without changing its physical form, preserving its original state as much as possible, so as to test the changes in the mechanical properties of the silk after degumming; 2. During the silk degumming process, the change in the conductivity of the test liquid can be used to determine whether the silk degumming is complete, so as to ensure the authenticity and accuracy of the silk degumming data; 3. The overall silk degumming process achieves controllable pH of the degumming liquid (adjusted by the degumming agent solution) and automation. The temperature, liquor ratio, etc. during the degumming process can be controlled, the degree of degumming completion can be automatically verified, and the degumming process can be programmed.

It is only for the convenience of describing this invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation structure and operation. Therefore, it should not be construed as a limitation of this invention.

[0020] like Figure 1-5 As shown, an automatic scouring device for mechanical testing of degummed silk includes a device body 1, an electric rotating platform 2, a degumming column 3, a winding mechanism 4, an electrically controlled moving brush device 5, a heating and temperature control device 6, a pure water inlet 7, a degumming agent solution inlet 8, a conductivity sensor 9, a controller 10, a cross-shaped connecting column 16, a rotating disk 17, a degumming agent solution chamber 18, and an observation window 22. The device body 1 includes a base 11, a housing 12, a main top cover 13, a secondary top cover 14, and a latch 15. A rectangular housing 12 is mounted on the base 11. The main top cover 13 is fixedly mounted on the top of the housing 12, and its four edges are fixedly and sealed to the top edge of the housing 12. The secondary top cover 14 is mounted at the center of the main top cover 13 via the latch 15. A hollow area for mounting the secondary top cover 14 is provided in the center of the main top cover 13, and the secondary top cover 14 can be locked or removed via the latch 15.

[0021] The device body 1 contains an electric rotating platform 2, a heating and temperature control device 6, and a conductivity sensor 9. The electric rotating platform 2 is located at the center of the device body 1, specifically at the center of the base 11. The heating and temperature control device 6 includes heating elements and a temperature sensor. The heating elements are distributed within the base 11, and their installation is similar to that of an electric kettle. The conductivity sensor 9 is directly fixed to the base 11 and is used to measure the conductivity of the liquid.

[0022] A degumming column 3 is detachably and vertically mounted on the electric rotating platform 2. The connection between the electric rotating platform 2 and the degumming column 3 is achieved through a cross-shaped connecting column 16. The cross-shaped connecting column 16 is mounted on the electric rotating platform 2, and a slot is provided at the bottom of the degumming column 3 to mate with the cross-shaped connecting column 16. The insertion and connection of the cross-shaped connecting column 16 allows the degumming column 3 to rotate with the electric rotating platform 2. A limiting ring is also provided on the electric rotating platform 2 to mate with the cross-shaped connecting column 16, and the limiting ring surrounds the bottom of the degumming column 3. To ensure the stability of the top of the degumming column 3 during rotation, a rotating disk 17 is rotatably mounted on the top of the degumming column 3. The rotating disk 17 is connected to the top of the degumming column 3 through a shaft and a bearing. The rotating disk 17 is in contact with the bottom of the sub-top cover 14, and the bottom of the sub-top cover 14 has a groove that matches the rotating disk 17. The vertical positioning of the cross-shaped connecting column 16 and the rotating disk 17 ensures the stable rotation of the degumming column 3 and facilitates the removal of the entire column for silk replacement.

[0023] The degumming column 3 is detachably equipped with several winding mechanisms 4 in the vertical direction; bundles of silk are placed on the winding mechanisms 4 and hooked together to ensure stable placement of the silk. The winding mechanism 4 includes a ring 41, connecting rods 42, a U-shaped fork 43, and a movable lock 44. The ring 41 is provided with a movable lock 44 that is movably connected to the degumming column 3. The ring 41 can move up and down on the degumming column and be fixed in a certain position by the movable lock 44 when it is moved to a suitable position. The movable lock 44 is a latch structure or a spring core structure. The degumming column 3 is provided with grooves, lock holes, and other structures that cooperate with the movable lock 44. Six connecting rods 42 are evenly arranged on the side of the ring 41. The U-shaped fork 43 is fixedly arranged outward at the front end of the connecting rod 42. One of the six connecting rods 42 is a spring telescopic rod, which includes a sleeve, a rod core, and a spring. The spring is provided inside the sleeve, and the rod core is slidably arranged inside the sleeve. The extension and retraction of the rod core is achieved by the spring. The winding mechanism 4 can straighten and stretch the bundled silk, making it convenient to assemble and disassemble the silk, and also making it easy to connect and separate from the degumming column 3.

[0024] Electrically controlled movable brush devices 5 are installed on both sides of the degumming column 3. These devices control the movement of the brushes to contact the silk fibers, thus achieving the washing of the silk. Each electrically controlled movable brush device 5 includes a brush 51, a limiting slide rod 52, an electric telescopic rod 53, and a drive rod 54. The limiting slide rod 52 is fixedly installed on the inner side of the housing 12. The brush 51 is slidably connected to the limiting slide rod 52. The height of the brush 51 is greater than the distribution range of the winding mechanism 4 on the degumming column 3, allowing the brush 51 to wash the silk fibers placed on the degumming column 3. At least two limiting slide rods 52 are provided, ensuring that the brush 51 moves back and forth in a straight line without rotating through double-point limiting. The front end of the limiting slide rod 52 is 2.0 cm away from the end of the winding mechanism 4. The electric telescopic rod 53 is fixedly installed behind the brush 51, close to the inner wall of the device body 1, and aligned with the vertical center line of the brush 51. One end of the drive rod 54 is connected to the top hinge of the electric telescopic rod 53, and the other end of the drive rod 54 is connected to the back hinge of the brush 51. The brush 51 is driven to move back and forth in a straight line by the extension or retraction of the electric telescopic rod 53. When the brush 51 moves to its farthest distance, the bristles on it can contact the degumming column 3.

[0025] A pure water inlet 7 and a degumming agent solution inlet 8 are provided on the top of the device body 1. Metering pumps are installed inside both inlet 7 and inlet 8. The pure water inlet 7 is connected to a pure water analyzer to meterly inject pure water into the device; the degumming agent solution is injected through inlet 8. During the silk degumming operation, the mass ratio of silk to degumming liquid is 1:200.

[0026] The device body 1 is also equipped with a draining device and an emergency stop button 21. The draining device is located on the left side of the base 11 and includes a drain port 18, a drain pipe 19, and an electric valve 20. The drain port 18 is located on the top left side of the base 11, and the drain pipe 19 is located on the left side of the base 11, communicating with the drain port 18. An electric valve 20 is installed on the drain pipe 19. The emergency stop button 21 is located on the right side of the device body 1.

[0027] A controller 10 and an observation window 22 are provided on the front of the device body 1. The observation window 22 is a glass window for observing the silk degumming process. The electric rotating platform 2, electric telescopic rod 53, heating and temperature control device 6, electric valve 20, conductivity sensor 9, and metering pump are electrically connected to the controller 10. A control panel is provided on the controller 10, which includes a power button, a setting button, an up button, a down button, a degumming button, a return button, and a display screen. The display screen has a master interface and sub-interfaces for operation, with each button corresponding to one of the master interface. The master interface is divided into a display interface and a setting interface. The display interface shows information such as actual and design values, local time, countdown, conductivity value, and temperature. Pressing the setting button enters the setting interface, which displays setting options for temperature, liquid inlet, time, and conductivity. Each option leads to a corresponding sub-interface. The setting button, up button, down button, degumming button, and return button are arranged from top to bottom to form the button interface. When an item is selected using the up or down arrow key, the background color of that item on the screen darkens.

[0028] Upon entering the sub-interface, the first button from top to bottom on the operation panel will be automatically locked: the "Settings" button. Entering the "Settings" interface, from top to bottom, you will find "Temperature Settings," "Liquid Injection Settings," "Time Settings," and "Conductivity Settings." The "Temperature Settings" sub-interface contains "Degumming Temperature" and "Cleaning Temperature." The "Liquid Injection Settings" sub-interface contains "Degumming Reagent" and "Pure Water." The "Time Settings" sub-interface contains "Degumming Time" and "Cleaning Time."

[0029] Up and down arrow keys: When the "Settings" key is pressed, you can select up and down on the sub-interface operation panel, and you can also set the value. Up means increase, and down means decrease. After each setting is completed, press the "Settings" key to save it.

[0030] Debonding button: After all conditions are set, press this button to start the debonding system.

[0031] Back button: Returns to the previous screen.

[0032] The controller 10 is equipped with a heating and temperature control system, an automated degumming system, a conductivity detection system, a liquid inlet and drainage system, and a forced stop system. The heating and temperature control system controls the operation of the heating and temperature control device, achieving control over the degumming and washing temperatures. The automated degumming system is the main control system, realizing fully automated control of the silk degumming process. The conductivity detection system controls the operation of the conductivity sensor, automatically testing and providing a value for the conductivity of the degummed liquid after each degumming step. The liquid inlet and drainage system can automatically add appropriate amounts of degumming agent solution and pure water via a metering pump, or discharge the liquid after each conductivity measurement via a drainage device. The forced stop system is associated with an emergency stop button, allowing for forced shutdown of the system to handle emergencies.

[0033] Operating principle: The operation of the cooking device of the present invention is divided into manual operation and automatic operation. Manual operation is the operation of the preparatory work, and automatic operation is the automatic control of the device.

[0034] Manual operation process: According to national standard (GB / T 1798-2008) and industry standard (FZ / T 40004-2023), first weigh and record the quality of the silk to be degummed. Manually wind and fix each strand of silk onto the winding mechanism of the degumming column. After the silk is hooked and fixed, set the relevant conditions for this degumming on the operation interface. After all conditions are set, press the degumming button on the operation interface, and the system will start degumming automatically.

[0035] The overall automated operation process is as follows: At the start of degumming, the degumming agent solution is discharged through a metering pump until the silk is completely submerged. Then, a constant temperature heating system continuously heats and controls the temperature. Once the solution temperature reaches the degumming temperature and standard conductivity, the degumming time automatically starts a countdown. The degumming column rotates 360° around its center Z-axis, and the silk rotates continuously with the column, achieving a stirring effect. After the countdown ends, the degumming column stops rotating, and the conductivity system detects the conductivity of the degumming solution and compares it to the set value. When the result is greater than the set conductivity value, the degumming operation is complete. After the degumming operation is completed, automatic cleaning begins. The inlet and outlet drainage system controls the discharge of the degumming solution. Once completely discharged, pure water is added via a metering pump, and the heating and temperature control system begins heating. Once the solution reaches the cleaning temperature, the cleaning timer automatically starts counting down. The automated degumming system controls the brushes to approach and contact the silk, applying gentle friction, slow pressure, and intermittent passage through the silk. This repeated friction between the brushes and the silk achieves a "hand-washing" cleaning effect. After the cleaning countdown ends, the conductivity system detects the conductivity of the cleaning solution. When the detection result is less than or equal to the set conductivity value, the cleaning is complete, and the inlet and outlet drainage system controls the discharge of waste liquid, completing one cleaning cycle. The system stops operating after cleaning is complete.
