[0044] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0045] Example
[0046] A silk fibroin gel drying device, such as Figure 1-6 As shown, it includes a power drive mechanism 1, a roller table mechanism 2, a blower mechanism 3, a sensor mechanism 4 and a control mechanism 5;
[0047] The roller table mechanism 2 comprises a plurality of rollers 21 arranged in parallel with each other, and each roller 21 is connected to each other through a roller transmission belt 23; the spacing between adjacent rollers 21 decreases from one side to the other side, and the silk fibroin gel blank is placed between adjacent rollers 21; the power drive mechanism 1 is connected to at least one roller 21 through a transmission belt 14;
[0048] The blower mechanism 3 includes a normal temperature fan group 31 and a heating fan group 32; the normal temperature fan group 31 is arranged below the roller 21 on the side with a larger spacing, and the heating fan group 32 is arranged below the roller 21 on the side with a smaller spacing;

[0050] The control mechanism 5 is electrically connected to the power driving mechanism 1 , the blower mechanism 3 and the sensor mechanism 4 .
[0051] More specifically, in this embodiment:
[0052] like Figure 1 As shown, the main body of the drying equipment is composed of a power drive mechanism 1, a roller table mechanism 2, a blower mechanism 3, a sensor mechanism 4 and a control mechanism 5.
[0053] like Figure 3 As shown, the roller table mechanism 2 includes a plurality of parallel rollers 21 for carrying the silk fibroin gel blank (the silk fibroin gel to be dried, hereinafter referred to as the gel blank), a roller transmission wheel 22 installed at one end of the roller 21, a roller transmission belt 23 connected between the roller transmission wheels 22, a support frame 24 for assembling the rollers 21, and a cover plate 25 installed on the top of the support frame 24 and capable of controlling the opening and closing of the drying space inside the drying device. The support frame 24 is the main supporting structure of the drying device, and the cover plate 25 is rotatably connected to the top surface of the support frame 24, and the rotatable connection can be realized in the form of hinge connection, hinge connection, etc., so that the gel blank can be placed in a relatively stable drying space as much as possible during the drying process, reducing the influence of the external environment on the gel blank. The drying device is provided with a plurality of rollers 21, which are stainless steel rollers 21, and are installed at a position near the top of the support frame 24 through bearings (the rollers 21 and the cover plate 25 must be at least spaced apart by a diameter of the gel blank), and the spacing between the rollers 21 decreases from the outside to the inside, so as to be able to adapt to the placement and drying of gel blanks in different drying stages / drying states. A roller transmission wheel 22 is installed at one end of each roller 21, extending out of the outside of the support frame 24, which can transmit external power to each roller 21 to drive the roller 21 to rotate, and can drive the rotation of the gel blank placed thereon through the rotation of the roller 21; and the roller transmission belt 23 is used to realize transmission connection between the rollers 22, so as to ensure that the rollers 21 can realize synchronous rotation, so that the rollers 21 can drive the gel blank to roll evenly, and ensure the circularity and straightness of the gel blank during the drying process.
[0054] like Figure 2 As shown, the power drive mechanism 1 includes a drive motor 11, a drive wheel 12, a positioning wheel 13 and a transmission belt 14. The drive motor 11 is assembled in the power compartment of the support frame 24, specifically located at the bottom of the support frame 24 and directly below the roller 21. The output end (output shaft) of the drive motor 11 extends out of the support frame 24, and the drive wheel 12 is installed on the motor shaft outside the support frame 24 (usually installed in the form of a key connection). On the outside of the support frame 24, there is also at least one positioning wheel 13 assembled by a rotating shaft, and the drive wheel 12, the positioning wheel 13 and at least one roller transmission wheel 22 are sequentially connected by the transmission belt 14. In this embodiment, a positioning wheel 13 is arranged outside the support frame 24 and the transmission belt 14 is connected to a roller transmission wheel 22 in transmission, and the driving motor 11 drives the roller 21 to rotate through the combined action of the transmission belt 14 and the roller transmission belt 23.
[0055] like Figure 4As shown, the air blowing mechanism 3 specifically includes a normal temperature fan group 31, a heating fan group 32, a fan fixing frame 33 and a baffle 34. Among them, the normal temperature fan group 31 is arranged under the roller 21 with a larger spacing (outer side) to perform preliminary air drying on the gel blank, and the heating fan group 32 is arranged under the roller 21 with a smaller spacing (inner side) to perform deep heating and air drying on the gel blank. The normal temperature fan group 31 includes a plurality of normal temperature fans, which can be arranged in a form such as side by side, array, or cross, so that the gel blank placed on the roller 21 can be evenly or basically evenly covered by the wind field; the heating fan group 32 includes a plurality of heating fans, which are similar to normal temperature fans and can also be arranged in a form such as side by side, array, or cross, so that the gel blank placed on the roller 21 can be evenly or basically evenly covered by the hot air field. In this embodiment, three normal temperature fans (outside) are arranged side by side under the roller 21, and four heating fans (inside) are arranged side by side and symmetrically under the roller 21; in some other embodiments, the design can be made according to the actual situation and needs. The heating fan can be an existing product with heating function (such as heating wire, heating tube, etc.). The normal temperature fan group 31 and the heating fan group 32 are horizontally installed inside the support frame 24 under the roller 21 through the fan fixing frame 33, so that the distance between the normal temperature fan group 31 and the heating fan group 32 and the roller 21 is fixed. In the space between the normal temperature fan group 31, the heating fan group 32 and the roller 21, there is also a baffle 34 with an opening, which allows wind to pass through and avoids damage to the normal temperature fan group 31 and the heating fan group 32 due to the falling of the gel blank. Furthermore, the opening shape and opening distribution on the baffle 34 are optimized and designed according to the wind field conditions on the basis of ensuring that the gel blank can be received when it falls, so that the gel blank placed on the roller 21 can obtain a more uniform drying process. In this embodiment, slots are arranged at intervals, and the length and width of the slots should be respectively smaller than the length and diameter of the corresponding processed gel blank after drying, so as to prevent the gel blank from falling through the baffle 34. Furthermore, the slots of the baffle 34 are located directly below the gap between the rollers 21, so as to ensure that the concentrated area of blowing is just in the area where the gel blank is placed, so as to minimize the obstruction during the blowing and drying process. The baffle 34 can be assembled between the support frames 24 in a retractable manner, such as in the form of a slide rail or a slide groove, and then, when the gel blank falls, the gel blank can be quickly and conveniently removed by extracting the baffle 34, which can prevent workers from reaching their hands into the depths of the drying equipment, further improving the safety of use. In order to further prevent the gel blank from sliding off when the baffle plate 34 is extracted, a vertical baffle bar may be provided on the innermost side of the baffle plate 34 .
[0056] like Figure 5As shown, the sensing mechanism 4 includes a temperature and humidity sensor 41, a visual sensor 42 and a rotation speed sensor 43, each of which is used to detect the temperature and humidity of the drying space, to observe the changes of the gel blank during the drying process, and to measure the rotation speed of the roller 21. The temperature and humidity sensor 41 is arranged on the inner side of the support frame 24, close to the roller 21, so as to more accurately obtain the environmental state of the drying space where the gel blank is located during the drying process. The visual sensor 42 can be arranged on the inner side of the support frame 24, facing the gap between the rollers 21, and / or, the visual sensor 42 can also be arranged on the inner side of the cover plate 25, facing the roller 21; the visual sensor 42 can obtain a picture of the gel blank during the drying process, and then the morphology and size data of the gel blank can be obtained by image processing, so that the drying state can be judged by the change in the diameter of the gel blank. According to actual needs, multiple visual sensors 42 should be provided to obtain the state of all gel blanks in the drying space. The speed sensor 43 may be connected to the roller 21 to directly obtain the rotation speed of the roller 21; or it may be connected to the output shaft of the drive motor 11, and / or the drive wheel 12, and / or the roller transmission wheel 22 to calculate the rotation speed of the roller 21 by determining the transmission ratio. Each sensor is electrically connected to the control mechanism 5 to feed back the specific data detected to the control mechanism 5.
[0057] like Figure 6 As shown, the control mechanism 5 includes a speed knob 51, a normal temperature fan switch 52, a heating fan switch 53, a wind speed knob 54 and a temperature controller 55. The speed knob 51 is electrically connected to the drive motor 11, and is used to adjust the output speed of the drive motor 11, and then the speed of the roller 21 can be adjusted; the speed knob 51 is installed on the front panel of the support frame 24 for easy operation. The normal temperature fan switch 52 is electrically connected to the normal temperature fan group 31, and is used to control the start and stop of the normal temperature fan group 31; the normal temperature fan switch 52 is installed on the front panel of the support frame 24 for easy operation. The heating fan switch 53 is electrically connected to the heating fan group 32, and is used to control the start and stop of the heating fan group 32; the heating fan switch 53 is installed on the front panel of the support frame 24 for easy operation. The wind speed knob 54 is electrically connected to the normal temperature fan group 31 and the heating fan group 32, and is used to control the speed of both, and then adjust the drying air volume and wind speed; the wind speed knob 54 is installed on the front panel of the support frame 24 for easy operation. The temperature controller 55 is electrically connected to the heating fan group 32. By adjusting the temperature controller 55, the heating temperature of the heating fan group 32 can be adjusted; the temperature controller 55 is also installed on the front panel of the support frame 24 for easy operation.
[0058] Furthermore, in order to improve the degree of automation of the drying equipment, the control mechanism 5 of the present solution may also include a central controller, which is electrically connected to the speed knob 51, the normal temperature fan switch 52, the heating fan switch 53, the wind speed knob 54 and the temperature controller 55, as well as the temperature and humidity sensor 41, the visual sensor 42 and the speed sensor 43, respectively, to realize the automatic control of the drying equipment. The central controller may be a controller with certain programming capabilities such as a PLC controller or a single-chip microcomputer, which performs calculations, judgments and other steps based on the real-time data fed back by the sensor, and instructs each adjustment structure to make appropriate adjustments. The adjustment process satisfies the following relationship:
[0059]
[0060] Wherein, D is the target diameter of the silk fibroin gel blank (mm), D0 is the initial diameter of the silk fibroin gel blank (mm); T0 is the ambient temperature (usually it can be considered as 25°C to simplify the calculation. If the deviation is large, the actual ambient temperature should be brought in for calculation), T is the heating temperature of drying (i.e., the heating temperature of the heating fan group 32, the temperature of the drying space, obtained by the temperature and humidity sensor 41); t is the drying time; λ c is the influence coefficient of the wind speed of the blower unit 3 (normal temperature fan group 31 and heating fan group 32) on the drying process (between 1 and 1.5), v is the influence coefficient of the rotation speed of the roller 21 on the drying process (between 1 and 1.5).
[0061] Specifically, in this embodiment: the speed knob 51 can be designed to have 3 gears. The higher the gear, the faster the speed of the roller 21, and correspondingly, the faster the turning speed of the gel blank; the normal temperature fan switch 52 and the heating fan switch 53 have two gears, on and off, representing start and stop respectively; the wind speed knob 54 is set to 3 gears. The higher the gear, the faster the fan speed, and correspondingly, the greater the air volume and wind speed, the faster the drying; the adjustable range of the temperature controller 55 is 30-60°C, providing a mild drying temperature for hot air drying of the gel blank. Based on the above settings in this embodiment, in the above formula: T is in the range of 30-60°C; t is in the range of 24-72 hours; λ c According to the number of gears, it can be divided into: 1 gear, λ c =1.0, 2nd gear, λ c =1.3, 3rd gear, λ c =1.5;λ v According to the number of gears, it can be divided into: 1 gear, λ v =1.0, 2nd gear, λ v =1.1, 3rd gear, λ v =1.2. Through the above formula and related parameter settings, the drying process can be regulated in real time to meet the needs of the drying process.
[0062] When the drying equipment is working, the gel blank is first placed in the gap of the roller 21, the driving motor 11 is started and the roller 21 is driven to rotate through the transmission belt 14 and the roller transmission belt 23, so that the gel blank follows the roller 21 to rotate evenly. The cover plate 25 is covered to place the gel blank in a relatively stable drying space, and then the normal temperature fan group 31 is started and adjusted to a suitable fan speed for normal temperature air drying (about 24h to 48h) to evaporate the internal moisture of the gel blank; after the size and diameter of the gel blank are reduced to a stable state, the heating fan group 32 is turned on and the heating temperature and fan speed are adjusted to heat and dry the gel blank. During the drying process, each sensor monitors the state of the gel blank and the drying space, and adjusts the drying parameters through the central controller. After the gel blank is dried and shrunk into a hard, uniformly colored yellow-brown rod, it means that the drying is completed, and the dried silk fibroin gel rod can be removed for the next machining process.
[0063] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
