Description

TECHNICAL FIELD

[0001] The utility model belongs to the cigarette production technical field, concretely relates to a sink jacking device and tobacco stem moisture regaining machine. BACKGROUND

[0002] The sink type tobacco stem moisture regaining machine is a special equipment for cleaning, removing dirt and directly regaining moisture of tobacco stems on the tobacco stem branch line of the front section of the tobacco industry silk production line. Its working principle is that according to the specific gravity difference of the foreign matters such as soil and sand mixed in the incoming material and water, after being fully mixed with water, the dust is dissolved in water, and the foreign matters such as sand and metal are deposited, so that the purpose of washing stems is achieved. Meanwhile, the tobacco stems can be warmed and humidified after being immersed in warm water. The water in the high and low water tanks is circulated and forms a water level difference under the action of the water pump. The water in the high water tank and the material enter the ''S'' shaped cleaning channel at the inlet respectively. In the flow process of water from high to low, the tobacco stems are fully mixed with water and enter the separation tank. The foreign matters such as sand and metal sink to the bottom of the separation tank, and the tobacco stems flow into the chain mesh conveyor chain mesh belt with water, so that the tobacco stems and water begin to separate. The water is drained during the conveying process, and the tobacco stems are conveyed to the next process. The water flows back to the water tank through the water collecting tank at the bottom of the conveyor.

[0003] According to the equipment maintenance requirements, after the production is completed every day, the sundries in the sink are cleaned, the sewage in each water tank is discharged, the accumulated material at the bottom of the water tank is washed clean, and the conveyor is cleaned. However, the sundries in the water tank need to be cleaned by lifting the sink to facilitate personnel to enter the water tank for cleaning. However, the lifting of the sink is manually operated. After one person lifts the sink, another person enters the water tank for cleaning. However, the sink is heavy, and two people need to work together. There is a security risk that two people do not cooperate well and do not support the sink, which may injure the personnel. UTILITY MODEL CONTENTS

[0024] First, the utility model embodiment provides a sink jacking device, please refer to Figure 1 、 Figure 2 , mainly including sink 1, cylinder 2 and support rod 3.

[0025] Please refer to Figure 1 、 Figure 2 In the embodiment of the application, the sink jacking device includes sink 1, cylinder 2 and support rod 3, support rod 3 and cylinder 2 are arranged below sink 1, sink 1 bottom is provided with support part 4, the telescopic end of cylinder 2 is fixedly connected with the lower surface of sink 1, and the initial position of sink 1 is as shown inFigure 1 As shown (where the support rod 3 is not shown), when the device needs to be maintained, the air cylinder 2 is started to push the water tank 1 to rise, when the water tank 1 rises to a certain height, the air cylinder 2 stops, one end of the support rod 3 abuts against the support part 4, and the other end is fixed to a point, which further supports the water tank 1 (as shown in Figure 2 As shown), after cleaning, the support rod 3 is lowered, and the air cylinder 2 drives the water tank 1 to descend back to the initial position. The air cylinder 2 is used to lift the water tank 1 and then clean and maintain the device, the air cylinder 2 can provide stable support force to the water tank 1, which improves the safety of the entire cleaning process. Then the support rod 3 is arranged to support the water tank 1, even if the air cylinder 2 is mistakenly turned off, the support rod 3 can prevent the water tank 1 from accidentally falling down, which ensures the convenience of operation, reduces the labor intensity, and reduces the safety hidden danger.

[0026] It should be noted that the orientation description between the components in the embodiments of the present application is based on the reference of the visual angle. The water tank 1 is welded by a stainless steel plate. Figure 1

[0027] In an implementation, a conveyor 5 is arranged on one side of the water tank 1, one end of the water tank 1 abuts against the conveyor 5, and the other end is rotatably connected to the rack, and the height of the end of the water tank 1 abutting against the conveyor 5 is lower than the height of the other end connected to the rack, which makes the water tank 1 initially in an inclined state, facilitating the tobacco stem to flow onto the conveyor 5.

[0028] In an implementation, the first end of the support rod 3 is fixedly connected with the motor shaft of the driving motor, when the air cylinder 2 pushes the water tank 1 to rise to a certain height, the driving motor is started to drive the support rod 3 to rotate, so that the second end of the support rod 3 abuts against the support part 4 arranged at the bottom of the water tank 1.

[0029] In an implementation, the support part 4 is a plurality of protrusions arranged at the bottom of the water tank 1 at equal intervals, the plurality of protrusions are integrally connected with the bottom of the water tank 1, the driving motor drives the support rod 3 to rotate, and the second end of the support rod 3 is embedded between two adjacent protrusions, thereby supporting the water tank 1.

[0030] Further, the protrusions are in a tile shape, the surface of the protrusion can guide the second end of the support rod 3 when the second end of the support rod 3 abuts against the surface of the protrusion, so that the support rod 3 can stably support the water tank 1.

[0031] Preferably, as shown, the second end of the support rod 3 is provided with a trapezoidal cross section, the second end of the support rod 3 is embedded between two adjacent protrusions, the second end of the support rod 3 has a large contact area with the water tank 1, and has more stress points, which can ensure the structural stability of the support rod 3 and the water tank 1. Figure 2

[0032] ​​In one possible implementation, a proximity switch is provided at the end of the conveyor 5 that abuts against the water tank 1. The proximity switch is used to detect the position of the water tank 1 relative to the conveyor 5. The proximity switch converts the detected position signal of the water tank 1 relative to the conveyor 5 into an electrical signal and transmits it to the control unit. The control unit controls the retraction speed of the cylinder 2 according to the electrical signal transmitted by the proximity switch, thereby buffering the speed and avoiding mechanical collisions between the water tank 1 and the conveyor 5 due to inertia.

[0033] In one possible implementation, cylinder 2 is located on the left side of support rod 3, and drive motor drives support rod 3 to rotate counterclockwise to support water tank 1. The support point of support rod 3 is located at the end of water tank 1 away from the center of rotation of water tank 1. The torque at the support point of support rod 3 is relatively long, so the force on support rod 3 is small, ensuring the support strength of support rod 3. Furthermore, the fact that cylinder 2 is located on the left side of support rod 3 and drive motor drives support rod 3 to rotate counterclockwise avoids interference between support rod 3 and drive motor.

[0034] In one possible implementation, the cylinder 2 is arranged at an angle, with the cylinder 2 tilted towards the direction of the support rod 3, so that the connection point between the cylinder 2 and the water tank 1 is far away from the rotation center of the water tank 1. The applied torque of the cylinder 2 is longer, and the cylinder 2 can lift the water tank 1 with a smaller force, thus reducing the load on the cylinder 2 when it is working.

[0035] Secondly, this utility model embodiment also provides a tobacco stem rehumidification machine, including the above-mentioned water tank lifting device and a stem washing box. The water tank lifting device is disposed inside the stem washing box. Specifically, the other end of the water tank 1 can be rotatably connected to the inner wall of the stem washing box.
