Description

Technical Field

[0001] The utility model relates to the technical field of tobacco, in particular to a temperature control system of a tobacco drying machine. Background Art

[0002] The tobacco dryer temperature control system is a system used to control the temperature inside the tobacco dryer. The tobacco dryer is a device used to heat and dry tobacco leaves, and is commonly used in the tobacco processing industry. The tobacco leaves undergo a heating and drying process inside the tobacco dryer to achieve the appropriate moisture content and quality. The temperature control system plays a key role in the tobacco dryer. It can monitor and adjust the temperature inside the tobacco dryer to ensure that the tobacco leaves are properly heated and dried, and avoid overheating or overcooling that may cause the quality of the tobacco leaves to deteriorate or the equipment to be damaged. Existing tobacco dryer temperature control systems usually include temperature sensors, controllers, and actuators. The temperature sensor is used to monitor the temperature changes inside the tobacco dryer in real time and transmit the data to the controller. Based on the sensor data and preset parameters, the controller controls the actuators (such as heating elements, fans, etc.) to adjust the temperature of the tobacco dryer to keep it within the set range.

[0003] Tobacco leaves need to be precisely heated and dried during the processing, and temperatures that are too high or too low will affect the quality of the tobacco leaves. The temperature control system can ensure that the tobacco leaves are heated and dried at appropriate temperatures, thereby ensuring the stable quality of the final product. If the parameters of the control system are improperly set or adjusted inaccurately, the temperature of the tobacco drying machine may fluctuate too much or fail to stabilize within the set range. The prior art changes the air supply volume by changing the air pressure at the air supply source. In fact, because there are many branches in the air supply pipeline and a large number of air outlets, it is impossible to ensure that different exhaust ports have equal outlet pressures by simply changing the air supply source. For example, the outlet pressure closer to the air source is sufficient, while the outlet pressure farther away from the air source is insufficient, resulting in uneven exhaust volume with the air supply pressure.

DETAILED DESCRIPTION

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0028] like Figure 1 As shown, a temperature control system for a tofu drying machine includes: a sorting equipment frame 1, an air inlet pipe 2, an adjustment mechanism 3 and an exhaust mechanism 4, etc.

[0029] like Figure 2 As shown, the sorting equipment frame 1 is a frame structure, including: a vertical standpipe 11, a crossbeam 12 and a longitudinal beam 13, and the crossbeam 12 and the longitudinal beam 13 are fixed to the upper part of the vertical standpipe 11. Specifically, an air inlet pipe 2 is arranged along the left longitudinal beam 13 of the sorting equipment frame 1, and the inlet end of the air inlet pipe 2 is connected to the heating mechanism. An adjustment mechanism 3 is arranged at the right longitudinal beam 13 of the sorting equipment frame 1.

[0030] like Figure 3 As shown, the adjustment mechanism 3 includes: a sliding sleeve 31, a push rod seat 32, an electric push rod 33, a lifting beam 34, a rack 35 and a gear 36. The sliding sleeve 31 is sleeved on the outer top of the vertical riser 11, and the left and right sides of the sliding sleeve 31 are respectively fixedly connected to the lifting beam 34. The electric push rod 33 is installed on one side of the sliding sleeve 31. The lifting beam 34 arranged at a position corresponding to the electric push rod 33 is provided with a through hole. When the electric push rod 33 is fixed to the push rod seat 32, the telescopic rod of the electric push rod 33 is led out from the through hole, and the top of the telescopic rod of the electric push rod 33 is fixed below the longitudinal beam 13.

[0031] like Figure 3 In the embodiment, a rack 35 is vertically fixed at the lower part of the lifting beam 34 , and the rack 35 is sealed and sleeved on the inner side of the vertical riser 11 .

[0032] The exhaust mechanism 4 includes a fixed outer sleeve 41, a fixed exhaust hole 42, a rotating inner sleeve 43 and a dynamic exhaust hole 44. Figure 3 and Figure 4As shown, the fixed outer sleeve 41 is fixed between adjacent vertical risers 11, and is at least connected to the inner cavity of the vertical riser 11 on the left. A series of fixed exhaust holes 42 are evenly distributed on the surface of the fixed outer sleeve 41. A rotating inner sleeve 43 is matched and mounted inside the fixed outer sleeve 41. A gear 36 is installed at the right end of the rotating inner sleeve 43, and the gear 36 is meshed with the rack 35. A series of dynamic exhaust holes 44 are evenly distributed on the surface of the rotating inner sleeve 43, and it is ensured that the width of adjacent dynamic exhaust holes 44 is consistent with the width of adjacent fixed exhaust holes 42, and each dynamic exhaust hole 44 corresponds to the position of the fixed exhaust hole 42. When the rotating inner sleeve 43 is rotated, the degree of correspondence between the dynamic exhaust hole 44 and the fixed exhaust hole 42 can be changed. When the dynamic exhaust hole 44 is directly opposite to the fixed exhaust hole 42, the air volume is the largest. When the two are partially misaligned, the air volume becomes smaller. When the two are completely misaligned, no air is exhausted. Thus, the controller controls the extension and retraction of the electric push rod 33, thereby controlling the relative distance between the lifting beam 34 and the longitudinal beam 13. A series of racks 35 are carried under each lifting beam 34. When the lifting beam 34 moves up and down, a series of racks 35 move up and down at the same time. Each rack 35 can drive a series of gears 36 to rotate. When each gear 36 rotates, the exhaust volume of the exhaust mechanism 4 of the corresponding group can synchronously control the size of the air outlet. The above device can ensure uniform exhaust and keep each exhaust port able to synchronously adjust the exhaust volume, always ensuring that each exhaust port has a balanced and sufficient air supply pressure regardless of the distance from the air source.

[0033] In actual operation, when the wire drying machine is started, the controller starts to monitor the temperature and air flow, and the sensor monitors the temperature inside the wire drying machine in real time and transmits the data to the controller. According to the temperature monitoring data, the controller adjusts the relative distance between the lifting beam 34 and the longitudinal beam 13 by controlling the telescopic length of the electric push rod 33. This will affect the air volume of the exhaust mechanism 4 to adjust the air flow in the system. As the telescopic length of the electric push rod 33 is adjusted, the rotating inner sleeve 43 in the exhaust mechanism 4 will rotate, changing the degree of correspondence between the dynamic exhaust hole 44 and the fixed exhaust hole 42, thereby adjusting the air volume. Through the design of the exhaust mechanism 4, the system can achieve uniform exhaust, ensure uniform air flow inside the entire wire drying machine, and avoid local temperatures that are too high or too low. The design of the exhaust mechanism 4 can keep the air supply pressure of each exhaust port balanced, and can provide balanced and sufficient air supply pressure regardless of its distance from the air source. The controller monitors the temperature, air flow and exhaust volume in real time, and adjusts them according to the set parameters to ensure stable operation of the system. Through the above real-time process adjustment and monitoring, the tofu drying machine temperature control system can maintain stable temperature control and air flow during operation, improve production efficiency and ensure product quality.

[0034] Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various choices and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is limited by the claims and their equivalents.
