[0033] See Figures 1-5 A cocoon boiling machine with temperature control, comprising:

[0034] The cocoon cooking box 1 is in a square structure, which facilitates single-time accommodation of more cocoon and improves cocoon cooking efficiency. An electric heating pipe 6 is installed at the bottom of the cocoon cooking box 1, and the water flow in the box can be heated through the electric heating pipe 6. A bottom frame 7 for separating the electric heating pipe 6 is also placed in the cocoon cooking box 1, which prevents the subsequent cocoon cooking frame 51 from directly contacting the electric heating pipe 6. Further, at least one temperature sensor 8 is installed in the cocoon cooking box 1, which is installed at the middle layer position of the cocoon cooking box 1 to avoid being too close to the electric heating pipe 6 and affecting the detection accuracy. In this embodiment, two temperature sensors 8 are installed, which can detect the water temperature through the temperature sensor 8, and by comparing the values of the two temperature sensors 8, it can be judged whether the water flow in the cocoon cooking box 1 is uniformly heated. Further, in some embodiments, to realize automatic control of the water temperature, the electric heating pipe 6 and the temperature sensor 8 can be connected to the controller, and the running power of the electric heating pipe 6 is controlled through the controller. The principle is: set the target temperature, obtain the water temperature through the temperature sensor 8, and transmit the temperature signal to the controller. After receiving the signal of the temperature sensor 8, the controller controls the on-off of the electric heating pipe 6 according to the target temperature, so that the water flow reaches the target temperature and maintains constant temperature. The controller can be a PID controller (proportional-integral-derivative controller), so as to realize accurate temperature control. It should be noted that the specific control method and circuit structure are prior art, and will not be described here.

[0035] The stirring mechanism 4 includes a first rotating shaft 45, a second rotating shaft 47, and a motor 41. The first rotating shaft 45 and the second rotating shaft 47 are both rotatably installed in the cocoon cooking box 1. The first rotating shaft 45 is provided with a first stirring blade 46, and the second rotating shaft 47 is provided with a second stirring blade 48. The first rotating shaft 45 and the second rotating shaft 47 are symmetrically arranged to facilitate uniform disturbance of the water flow in the cocoon cooking box 1, thereby improving the uniformity of water temperature distribution. The bottom ends of the first rotating shaft 45 and the second rotating shaft 47 pass through the cocoon cooking box 1, and the connection is sealed to prevent water leakage. The first rotating shaft 45 is fixedly connected with a first pulley 42 at the bottom end, and the second rotating shaft 47 is fixedly connected with a second pulley 43 at the bottom end. The first pulley 42 and the second pulley 43 are cross-connected through a transmission belt 44, so that the rotating directions of the first rotating shaft 45 and the second rotating shaft 47 are opposite. The motor 41 is connected with the first rotating shaft 45 through a shaft coupling. In use, the motor 41 drives the first rotating shaft 45 to rotate, and the transmission belt 44 drives the second rotating shaft 47 to rotate in the opposite direction. The two stirring shafts rotate in opposite directions and generate interfering water flow, forming turbulent flow. The turbulent flow can cover every corner of the cocoon cooking box 1, avoiding dead angles and improving the uniformity of water temperature distribution.

[0036] The cocoon cooking mechanism 5 comprises a cocoon cooking frame 51 and a cocoon cooking cage 53. The cocoon cooking frame 51 is a multi-layer structure, each layer is provided with a placing frame 52, and the cocoon cooking cage 53 is clamped in the placing frame 52. Under the action of gravity, the cocoon cooking cage 53 cannot move in the transverse direction, and when the cocoon cooking cage 53 needs to be removed, the worker only needs to pick up the cocoon cooking cage 53 upwards, so that the bottom of the cocoon cooking cage 53 is separated from the placing frame 52. In order to facilitate the water flow to pass through the cocoon cooking cage 53 and heat the cocoon in the cocoon cooking cage 53, the cocoon cooking cage 53 is uniformly provided with through holes 54 on each surface. Further, in order to facilitate the addition of cocoon into the cocoon cooking cage 53, the side surface of the cocoon cooking cage 53 is provided with a closable movable baffle 55, and the movable baffle 55 is also uniformly provided with through holes 54 to facilitate the water flow to pass through. One side of the movable baffle 55 is connected to the cocoon cooking cage 53 through a hinge, and the other side is connected to the cocoon cooking cage 53 through a closable movable lock buckle. The movable lock buckle is a prior art, and its structure and connection mode are not described here. Further, since the cocoon will float in water, a large amount of cocoon will gather at the top of the cocoon cooking cage 53 during cocoon cooking, and will be pressed and stacked, affecting the uniformity of heating. In order to improve the uniformity of cocoon heating, a partition plate 56 is arranged in the cocoon cooking cage 53, and the partition plate 56 is uniformly provided with through holes 54. The space in the cocoon cooking cage 53 is evenly divided into upper and lower layers by the partition plate 56, so as to improve the uniformity of cocoon distribution in the cocoon cooking cage 53 and ensure the uniformity of cocoon heating during water bath heating.

[0037] In some embodiments, an observation port 12 is formed on the side wall of the cocoon cooking box 1, and a reinforced glass 13 is arranged at the observation port 12. Through the reinforced glass 13, the worker can conveniently observe the situation in the cocoon cooking box 1.

[0038] In some embodiments, the cocoon cooking box 1 is respectively provided with a water inlet pipe 2 and a drain pipe 3. The water inlet pipe 2 is provided with a water inlet valve 21, and the end of the water inlet pipe 2 is communicated with two water inlet branch pipes 22. After the water inlet branch pipes 22 extend into the cocoon cooking box 1, they are bent downward, so that the water outlet is opposite to the bottom surface of the cocoon cooking box 1, thereby preventing displacement of the cocoon cooking frame 51 caused by water flow impact. The drain pipe 3 is provided with a drain valve 31 to facilitate the discharge of water in the cocoon cooking box 1.

[0039] In some embodiments, since the water bath temperature in high-altitude areas is difficult to heat to 100℃, the cocoon cooking box 1 can be designed in the form of a pressure cooker, thereby solving the problem that the water bath temperature is difficult to reach 100℃.

[0040] Specific working process:

[0041] The cocoon is loaded into the cocoon boiling cage 53, and the cocoon boiling cage 53 is placed on the placing frame 52, and the cocoon boiling frame 51 is evenly placed in the cocoon boiling box 1, the top cover 11 is covered, a relatively closed space is formed in the cocoon boiling box 1, heating is facilitated, and heat loss is reduced; the water inlet valve 21 is opened to add water to the cocoon boiling box 1, and the electric heating pipe 6 is started to heat the water. When heating, the water temperature can be heated to 30-40℃ first, and maintained for a period of time, so that the cocoon is fully soaked, the cocoon fully absorbs water, the quality of the cocoon is prevented from being damaged due to rapid temperature change, and after the soaking is completed, the water temperature is increased to the target temperature and maintained. Under high temperature treatment, the silk glue is dissolved, and after high temperature, cold water can be sprayed to maintain the state of the silk glue. After the cocoon boiling is completed, the cocoon boiling frame 51 is taken out, the cocoon boiling cage 53 is opened, and the cocoon is obtained. After multiple cocoon boiling, the sewage can be discharged by opening the drain valve 31, and new water can be added, so as to ensure the quality of the cocoon boiling. Further, when replenishing water, a filtering device can be arranged at the water inlet pipe 2 to reduce the impurity content in the water, so as to ensure the quality of the cocoon boiling.

[0042] Finally, it should be noted that the relationships, such as first and second, are merely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any such actual relationship or order between such entities or actions. Moreover, the term including, including or any other variant means to cover the non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
