Description

Technical Field

[0001] This utility model relates to the field of sheet-forming machine technology, specifically to an intelligent sheet-forming machine alkali tank with limiting and protection functions. Background Technology

[0002] Caustic soda flakes are caustic soda in flake form. The production of caustic soda flakes involves multiple steps, including evaporation and concentration, solid alkali forming, and flake making. Among these, solid alkali forming and flake making are completed using an intelligent flake forming machine. The molten alkali that has been evaporated and concentrated is temporarily stored in the alkali tank of the flake forming machine. The rotation of the drum of the flake forming machine causes the molten alkali in the alkali tank to adhere to the outer surface of the drum, allowing it to cool and form solid alkali. Then, a scraper is used to scrape the solid alkali off the drum in flake form to produce caustic soda flakes.

[0003] In existing intelligent flake forming machines, the drum rotates around its own axis during the flake forming process. During flake forming, the alkali tank moves closer to the drum, immersing the drum surface in the alkali solution within the tank. The rotating drum then carries the alkali solution away, allowing it to adhere to the drum surface for cooling and solidification. To ensure the alkali solution fully cools and solidifies after adhering to the drum surface, the immersion depth of the drum in the alkali solution needs to be controlled to achieve a uniform thickness of solid alkali on the drum surface. However, in current flake forming machines, the alkali tank is moved via a hand-cranked lifting device with a rigid connection to the tank. This makes it prone to excessive tank movement, resulting in insufficient immersion depth of the drum in the alkali solution. Consequently, the thickness of the alkali solution adhering to the drum surface does not meet requirements, directly affecting the cooling and solidification speed of the alkali solution. This not only impacts the quality of the caustic soda flakes but also easily damages the drum, shortening its lifespan. Utility Model Content

[0004] The present invention aims to provide an intelligent alkaline tank for a flake forming machine with limiting and protection functions, so as to improve the movement accuracy of the alkaline tank and avoid the problem of insufficient immersion depth of the drum in the alkaline solution caused by excessive movement distance of the alkaline tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent calcining machine alkali tank with limiting and protection functions, including an alkali tank body and a lifting mechanism for driving the alkali tank body to move. The lifting mechanism includes a suspension fixed above the alkali tank body, a rotating shaft rotatably mounted on the suspension, a driving component connected to the rotating shaft, and a sprocket fixed on the rotating shaft. A chain is fixed and wound on the sprocket, and the end of the chain away from the sprocket is fixed to the alkali tank body. A sensing control component is fixed on the suspension, and the sensing control component is electrically connected to a controller. The output end of the controller is electrically connected to the driving component. A trigger component is fixed on the rotating shaft, and the sensing control component is used to sense the trigger component and transmit the sensing signal to the controller.

[0006] The principle and advantages of this scheme are as follows: The alkali tank body is lifted using sprockets and chains. Due to the flexibility of the sprockets and chains, the movement distance of the alkali tank body is easier to control. Simultaneously, as the shaft rotates and drives the sprocket to extend and retract the chain, a trigger on the shaft rotates accordingly. When the alkali tank body moves to the required height, the trigger moves to the sensing control unit. The sensing control unit detects the trigger and transmits a signal to the controller, causing the controller to stop the drive unit, thus stopping the shaft's rotation. Ultimately, the alkali tank body stops at this position, preventing excessive movement that could lead to insufficient immersion of the drum in the alkali solution. This significantly improves the movement accuracy of the alkali tank body, limits its movement, and ensures the quality of the produced caustic soda flakes.

[0007] Preferably, as an improvement, the trigger is a lever, and the sensing control element is a toggle switch, with the lever abutting against the toggle switch.

[0008] With the above scheme, when the rotating shaft rotates and drives the sprocket to extend and retract the chain, the lever follows the rotating shaft until it contacts the toggle switch, thus triggering the toggle switch. The toggle switch transmits a signal to the controller, which then controls the drive components to stop working, causing the alkali tank body to stop at that position. This automatically stops the lifting and lowering of the alkali tank body, thus achieving better movement control of the alkali tank body and making its movement more precise.

[0009] Preferably, as an improvement, the sensing control includes a sensor that can sense the position of the trigger.

[0010] With the above scheme, after the sensor detects that the trigger has reached the designated position, it transmits the signal to the controller. The controller controls the working state of the drive component, thereby keeping the alkali tank body in the corresponding position. This method of controlling the alkali tank body by sensing is more intelligent than the method of using a lever to move a toggle switch, resulting in higher precision in the movement control of the alkali tank body and better limiting effect.

[0011] Preferably, as an improvement, there are two sensing control elements, which are distributed sequentially along the circumference of the rotating shaft.

[0012] With the above scheme, the two sensing control components are used to control and limit the lowest and highest positions of the alkali tank body when it is raised and lowered, so that the alkali tank body can be kept at a suitable height position. This makes it easier to control the movement of the alkali tank body and to control the depth of the drum immersed in the alkali solution.

[0013] Preferably, as an improvement, a fixed plate is fixed on the rotating shaft, and an indicator protrusion is provided on the fixed plate. The indicator protrusion faces the lever and is used to indicate the position of the trigger.

[0014] With the above scheme, the fixed plate is used to follow the rotation of the shaft, so that the indicator protrusion can move accordingly to indicate the position of the trigger, thereby facilitating the observation of the position of the trigger and understanding the position and height of the alkali tank body.

[0015] Preferably, as an improvement, the drive component includes a motor and a reducer, with the output shaft of the motor connected to the input shaft of the reducer via a belt, and the output shaft of the reducer fixedly connected to a rotating shaft.

[0016] By connecting a speed reducer to the motor, the rotation speed of the shaft can be reduced, which facilitates the lifting and lowering control of the alkali tank body and improves the accuracy of the movement control of the alkali tank body. The belt connection between the speed reducer and the motor, compared with the method of directly connecting the motor to the shaft, can prevent the motor from burning out when the sprocket and shaft jam, thus protecting the motor.

[0017] Preferably, as an improvement, the sensing control element and the trigger element are provided with an isolation protective cover.

[0018] The above solution provides an isolation and protection cover that can isolate and protect the sensing and control components and triggering components to prevent them from being corroded by alkaline solutions or alkaline dust. Attached Figure Description

Unless otherwise specified, the technical means used in the following embodiments are conventional means well known to those skilled in the art; the experimental methods used are all conventional methods; and the materials and reagents used are all commercially available.

[0024] Example 1

[0025] Intelligent caking machine alkali tank with limit and protection functions, such as Figure 1 and Figure 2 As shown, the system includes an alkali tank body 1 and a lifting mechanism for driving the alkali tank body 1 to move. The lifting mechanism includes a suspension 2 fixed above the alkali tank body 1. A rotating shaft 3 is rotatably mounted on the suspension 2 via a bearing. A driving component is connected to the rotating shaft 3. In this embodiment, the driving component includes a motor 4 and a reducer 5. The output shaft of the motor 4 is connected to the input shaft of the reducer 5 by a belt. The output shaft of the reducer 5 is fixedly connected to the rotating shaft 3.

[0026] A sprocket 6 is also fixed on the rotating shaft 3, and a chain 7 is fixed and wound on the sprocket 6. The end of the chain 7 away from the sprocket 6 is fixed to the alkali tank body 1. A sensing control element 8 is fixed on the suspension 2. In this embodiment, the sensing control element 8 is a toggle switch. The sensing control element 8 is electrically connected to a controller, and the output end of the controller is electrically connected to the drive element. A trigger element 9 is fixed on the rotating shaft 3. In this embodiment, the trigger element 9 is a lever that can abut against the toggle switch. The sensing control element 8 is used to sense the trigger element 9 and transmit the sensing signal to the controller. In this embodiment, the controller is a PLC controller.

[0027] Furthermore, this embodiment has two sensing control elements 8, which are sequentially distributed along the circumference of the rotating shaft 3. A fixed plate 10 is fixedly mounted on the rotating shaft 3, and an indicator protrusion 11 is fixedly mounted on the fixed plate 10. The indicator protrusion 11 faces the lever and is used to indicate the position of the trigger element 9. Additionally, an isolation protective cover 12 is provided outside the sensing control elements 8 and the trigger element 9.

[0028] In this embodiment, when it is necessary to bring the alkali tank body 1 closer to the drum, the motor 4 operates and, after being reduced in speed by the reducer 5 connected by the belt, transmits the rotational power to the rotating shaft 3. The rotating shaft 3 drives the sprocket 6 to rotate, causing the chain 7 to wind up. The chain 7 drives the alkali tank body 1 to rise, bringing it closer to the drum. As the rotating shaft 3 rotates, the lever follows its rotation and moves closer to the toggle switch. When the alkali tank body 1 moves to the predetermined position, the lever abuts against the toggle switch, triggering a toggle. The toggle switch transmits a signal to the controller, which then stops the motor 4, thereby stopping the rotating shaft 3, sprocket 6, and chain 7, thus keeping the alkali tank body 1 in that position.

[0029] The design of the lever and toggle switch allows the alkali tank body 1 to move to a predetermined position, making the movement control of the alkali tank body 1 more precise and effectively avoiding the situation where the drum is immersed in the alkali solution to an excessive depth due to excessive movement of the alkali tank body 1.

[0030] When it is necessary to move the alkali tank body 1 away from the drum, the motor 4 operates and the shaft 3 rotates in the opposite direction, the chain 7 is released, and the alkali tank body 1 descends and moves away from the drum under the action of gravity. When the alkali tank body 1 moves to the predetermined position, the lever abuts against another toggle switch and makes a toggle. The other toggle switch transmits a signal to the controller, and the controller controls the motor 4 to stop working, thereby stopping the shaft 3, sprocket 6 and chain 7, so that the alkali tank body 1 is kept at the lowest height position.

[0031] Two sensing control elements 8 are used to control and limit the lowest and highest positions of the alkali tank body 1 during lifting and lowering, respectively, so that the alkali tank body 1 can be kept at a suitable height position. This makes it easier to control the movement of the alkali tank body 1 and to control the depth of the drum immersed in the alkali solution. The fixed plate 10 is used to rotate with the rotating shaft 3, so that the indicating protrusion 11 can move with it to indicate the position of the trigger element 9, thereby facilitating the observation of the position of the trigger element 9 and knowing the height of the alkali tank body 1.

[0032] When the sprocket 6 and the shaft 3 jam, the slippage of the belt can prevent the motor 4 from burning out, thus protecting the motor 4. The isolation protective cover 12 can isolate and protect the sensing control element 8 and the trigger element 9 to prevent them from being corroded by alkaline solution or alkaline dust.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the structure of the sensing control element 8 is different. In this embodiment, the sensing control element 8 is a sensor, which can sense the position of the trigger element 9. Specifically, the type of sensor can be an ultrasonic sensor or a photoelectric sensor, etc. The specific sensing principle is a well-known technology, and the specific model selection can be adjusted according to the actual situation. These are all within the scope of the ability of those skilled in the art, and will not be elaborated here.

[0035] In this embodiment, after the sensor detects that the trigger 9 has reached the designated position, it transmits the signal to the controller. The controller controls the working state of the drive component, thereby keeping the alkali tank body 1 in the corresponding position. This method of controlling the alkali tank body 1 by sensing with a sensor is more intelligent than using a lever to move a toggle switch, resulting in higher precision in the movement control of the alkali tank body 1 and better limiting effect.

[0036] Example 3

[0037] This embodiment, based on embodiment 1 or embodiment 2, involves a snap-fit ​​connection between the chain 7 and the alkali tank body 1. Specifically, as shown... Figure 3 As shown, the chain 7 is connected to the alkali tank body 1 via a snap-fit ​​mechanism. This mechanism includes a T-shaped snap-fit ​​plate 13 fixed to the alkali tank body 1 and a snap-fit ​​seat 14 bolted to the end of the chain 7. A double-ended lead screw 15 is rotatably mounted on the snap-fit ​​seat 14. Both ends of the double-ended lead screw 15 are respectively fitted with and threadedly connected to snap-fit ​​claws 16. A through hole is provided in the middle of each snap-fit ​​claw 16, through which the snap-fit ​​seat 14 passes and slides in cooperation with the snap-fit ​​claw 16. The lower end of the snap-fit ​​claw 16 is hooked onto the snap-fit ​​plate 13. Furthermore, a spring 17 is connected between the snap-fit ​​claw 16 and the end of the snap-fit ​​seat 14. In this embodiment, the spring 17 is a compression spring, which provides a preload force to the snap-fit ​​claw 16 towards the middle side of the snap-fit ​​seat 14, ensuring a tight connection between the snap-fit ​​claw 16 and the snap-fit ​​plate 13.

[0038] In practical applications, the two jaws 16 hold the clamping plate 13 in place, thereby fixing the chain 7 to the alkali tank body 1. When it is necessary to remove the alkali tank body 1, the double-ended screw 15 is rotated, causing the two jaws 16 to move towards both ends of the double-ended screw 15 and move away from each other, thereby separating the jaws 16 from the clamping plate 13.

[0039] During the movement of the chuck 16, the chuck seat 14 and the double-ended lead screw 15 guide it together, so that the chuck 16 can move smoothly. At the same time, the chuck seat 14 restricts the rotation of the chuck 16, preventing the chuck 16 from rotating with the double-ended lead screw 14, so that the chuck 16 can only move along the axial direction of the double-ended lead screw 14.

[0040] The double-ended lead screw 15 and the clamping seat 14 limit the upper and middle parts of the clamping jaw 16 respectively, so that the clamping jaw 16 always remains in a vertical state, thus ensuring the clamping and fixing effect of the clamping jaw 16 on the clamping plate 13.

[0041] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
