Description

Technical Field

[0001] The invention relates to the technical field of raw material lifting, in particular to a raw material lifting machine for protective film production. Background Art

[0002] During the protective film production process, raw material elevators are used to transport materials such as base materials, masterbatches, and functional additives to the mixing or extrusion equipment. Traditional elevators primarily utilize screw conveyors, pneumatic conveyors, or bucket elevators to continuously transport raw materials from a low to high position. However, these devices typically utilize a single feed channel, requiring pre-mixing of different raw materials before elevatoring or secondary mixing via additional mixing equipment. Furthermore, during operation, existing elevators can easily cause raw materials to move due to mechanical vibrations and airflow disturbances, affecting the stability of material distribution.

[0003] The existing lifting device has the following defects: 1. It is unable to isolate and lift different raw materials, resulting in stratification of materials with large differences in density or particle size (such as base material and masterbatch) due to gravity or centrifugal force during transportation, affecting the subsequent mixing uniformity; 2. The lifting and mixing processes are separated and require additional stirring equipment, which not only increases energy consumption and space occupancy, but also increases the difficulty of mixing the raw materials after stratification, resulting in color difference or performance fluctuations in the final product; 3. The discharge of high-viscosity raw materials is not complete, and traditional flipping or discharging structures are difficult to adapt to raw materials with different physical properties, which can easily cause residue and affect the ratio accuracy; Therefore, in view of the above situation, there is an urgent need to develop a protective film production raw material elevator to overcome the shortcomings in current practical applications.

On the other hand, due to The raw materials are divided into several portions and added to multiple raw material lifting containers 4 for stirring and mixing. Since the amount of stirring is small, the requirements for the stirring equipment are reduced, and the raw materials can be fully stirred. In this way, the sufficiency of mixing can be further guaranteed, and the stratification of raw materials can be further avoided. Since the stirring equipment will not be overloaded, the service life of the stirring equipment can also be extended. Finally, after the multiple raw material lifting containers 4 reach the specified height, the intelligent control system 3 will control the flip component to start according to the detected data, and rotate the multiple raw material lifting containers 4 to a certain angle (greater than 90 degrees).

The operation is simple, and it can avoid the stratification of each raw material due to external factors during the transportation process, thereby affecting the uniformity of subsequent mixing and the production quality of the protective film, which provides convenience for the staff.

[0068] In one embodiment of the present invention, see Figures 1-11 , the lifting device 6 includes a drive motor, a lifting transmission member and a lifting frame 5, and the drive motor is fixedly mounted on the lifting frame seat 1;

[0069] The lifting transmission member is connected to the lifting frame seat 1 and the top plate 12 respectively, and is connected to the driving motor, and a lifting frame 5 is also provided on the lifting transmission member.

[0070] The lifting transmission member may be a structure in which gears and an internal toothed belt cooperate, or a structure in which a chain and a sprocket cooperate, and the lifting frame 5 is connected to the internal toothed belt or the chain.

[0071] The flip assembly includes:

[0072] A turning motor 17, wherein the turning motor 17 is fixedly connected to the lifting frame 5, and a turning frame 10 is fixedly mounted on the output end of the turning motor 17, and the turning frame 10 is fixedly connected to the plurality of raw material lifting containers 4;

[0073] and an L-shaped auxiliary support plate 20, one end of which is fixedly connected to the raw material lifting container 4, and the other end of which is connected to the lifting frame 5 via a connecting adsorption portion 27;

[0074] Among them, after the raw materials are lifted to the designated position, the flip motor 17 drives the flip frame 10 to drive multiple raw material lifting containers 4 to flip and unload the materials, and the other end of the L-shaped auxiliary support plate 20 is automatically separated from the lifting frame 5.

[0075] It also includes: a limiting slide 9, one end of which is fixedly connected to the lifting frame 5;

[0076] and a lifting chute 23, the lifting chute 23 is located in the multifunctional support beam 2 and is slidably connected to the other end of the limiting slide 9;

[0077] There are two limit slides 9 and two lifting slides 23 , which are respectively located on both sides of the lifting frame 5 .

[0078] In the process of the raw materials being lifted, the driving motor will drive the internal toothed belt or chain to move, thereby driving the lifting frame 5 to move upward. In this process, the two limit slides 9 will slide in the two lifting chutes 23 respectively to ensure the stability of the rise or fall of multiple raw material lifting containers 4. After the lifting frame 5 reaches the specified height, the intelligent control system 3 will control the flip motor 17 to start, thereby driving the flip frame 10 to rotate around the output end of the flip motor 17. During the rotation of the flip frame 10, multiple raw material lifting containers 4 can be rotated by a certain angle, and finally all or part of the raw material lifting containers 4 are lifted and lowered through the discharge guide trough portion 1. 1 is discharged outwardly. In addition, through the provided connecting adsorption portion 27, wherein the connecting adsorption portion 27 can be in the form of an electromagnet, the electromagnet is located on the lifting frame 5, and a magnet bar is provided at the end of the L-shaped auxiliary support plate 20. During the normal lifting or lowering process of the raw material lifting container 4, the end of the L-shaped auxiliary support plate 20 contacts the lifting frame 5. At this time, the electromagnet is energized and generates a magnetic attraction with the magnet bar to further ensure the stability of the raw material lifting container 4 during the up and down movement. When the raw material lifting container 4 is turned over, the electromagnet can be turned off or the direction of the current can be changed, so that the L-shaped auxiliary support plate 20 loses its magnetic attraction, which facilitates the smooth turning of the raw material lifting container 4.

[0079] In one embodiment of the present invention, see Figures 1-11 , the stirring and mixing component includes:

[0080] A stirring and mixing structure 19, one end of which passes through the bottom end of the raw material lifting container 4 and extends into the raw material lifting container 4, and the other end of which passes through the L-shaped auxiliary support plate 20, and the stirring and mixing structure 19 is also rotatably connected to the raw material lifting container 4 and the L-shaped auxiliary support plate 20;

[0082] and a reciprocating drive unit, wherein the reciprocating drive unit is connected to the multifunctional support beam 2, the lifting frame 5 and the transmission shaft 14 respectively.

[0083] The reciprocating drive unit comprises:

[0084] A limit slot 22, wherein the limit slot 22 is fixedly mounted on the lifting frame 5, and a reciprocating slide 15 is slidably mounted in the limit slot 22, and a plurality of driving tooth plates 16 are provided on the reciprocating slide 15;

[0087] And a push rod 21, one end of which is fixedly connected to the reciprocating slide 15, and the other end of the push rod 21 is provided with an elastic buffer portion 26, and the end of the elastic buffer portion 26 is rotatably mounted with a rolling wheel 25, and the rolling wheel 25 is rollingly connected to the wave-shaped driving portion 24.

[0088] During the upward movement of the multiple raw material lifting containers 4, in addition to one end of the limiting slide plate 9 sliding in the lifting chute 23, the elastic buffer portion 26 on the elastic buffer portion 26 also rolls on the wavy driving portion 24, wherein the elastic buffer portion 26 can undergo slight deformation, such as using a part of the structure to adopt rubber material or a spring form to avoid the phenomenon that the rolling wheels 25 at both ends of the reciprocating slide plate 15 are stuck when rolling on the two wavy driving portions 24 respectively, which can play a certain buffering role. As the multiple raw material lifting containers 4 move upward, the rolling wheels 25 will roll on the wavy driving portion 24, and since there is an anti-phase wave between the two wavy driving portions 24, the directions of the wave crest and the wave trough are just opposite, then under the pushing action of the wavy driving portion 24, the reciprocating slide plate 15 will be in the limiting slot 22 The mixing and stirring mechanism 19 is rotated by the rotating shaft 14, and the stirring and stirring mechanism 19 is rotated by the rotating shaft 14. The stirring ... Figure 7As shown, a rocker arm 28 is provided on the flip frame 10, and the rocker arm 28 rotates around the connection portion between the transmission shaft 14 and the stirring and mixing structure 19 and the output end of the flip motor 17, and the two rocker arms 28 are also respectively connected to the two raw material lifting containers 4 provided at the outermost ends, so that the flip motor 17 can drive multiple raw material lifting containers 4 to rotate around a collinear virtual axis through the rocker arm 28, which will not be elaborated here. When the flip motor 17 drives the flip frame 10 to drive multiple raw material lifting containers 4 to rotate, the multiple raw material lifting containers 4 will be caused to rotate around the connection portion between the transmission shaft 14 and the stirring and mixing structure 19, thereby ensuring that the raw material lifting containers 4 are smoothly flipped for discharge.

[0089] In one embodiment of the present invention, see Figure 1 The intelligent control system 3 includes a raw material ratio control module, a turnover discharge adaptive module and a data feedback and optimization module;

[0090] The raw material ratio control module is used to allocate different raw materials to all or part of the containers according to processing requirements, and monitor the weight of the raw materials in each container in real time to ensure the ratio accuracy;

[0091] The flipping and discharging adaptive module dynamically adjusts the container flipping angle and shaking frequency based on the raw material viscosity data to ensure complete discharging;

[0092] The data feedback and optimization module collects mixing uniformity and discharge residual data through sensors, feeds back to the control system, and optimizes parameters in real time.

[0093] The working mode of the raw material ratio control module includes: calculating the amount of raw materials to be loaded into each raw material lifting container 4 according to the recipe requirements, and controlling the opening of the discharge valve on the discharge device to meet the following requirements:

[0094] ;

[0095] Among them, m i,j is the mass of the jth raw material in the i-th container, k j is the formula ratio coefficient, M i is the total capacity of container i; if the subsequent processing requirements change, the number of containers participating in the work is dynamically adjusted, and only some containers are fed with materials.

[0096] The working method of the flipping and discharging adaptive module includes: obtaining the raw material viscosity η through the viscosity sensor or historical process data set in the raw material lifting container 4, and dynamically adjusting the flipping angle θ:

[0097] ;

[0098] Wherein, α is the correction coefficient related to the inner wall material of the container; for high-viscosity raw materials, a high-frequency micro-vibration effect of 13 (frequency f ≥ 50 Hz) is added to reduce residue.

[0099] The working method of the data feedback and optimization module includes: detecting the residual amount Δm of the container after discharge through the weighing sensor set on the raw material lifting container 4, and if the residual amount is large, increasing the turning angle of the raw material lifting container 4 or the vibration amplitude of the vibrator 13.

[0100] This intelligent control system 3 achieves precise control and adaptive optimization during the raw material lifting process through the collaborative work of multiple modules, thereby bringing multiple technical benefits. The system first automatically calculates the raw material loading amount of each container based on the formula ratio, and accurately controls the isolated feeding of raw materials with different physical properties through the discharge valve, avoiding the stratification problem caused by traditional premixing methods at the source, and improving the subsequent mixing uniformity by more than 50%. When the container reaches the specified height, the system automatically adjusts the flip angle and superimposes high-frequency vibration based on the real-time detection of raw material viscosity data, so that even the discharge rate of high-viscosity raw materials can reach more than 99.2%, an increase of 8 percentage points compared to traditional discharge methods. The entire process uses NIR sensors and weighing devices to monitor the mixing uniformity and discharge residue in real time, forming a closed-loop feedback control. This not only ensures the stability of product quality, but also enables the equipment to automatically optimize operating parameters according to the characteristics of different raw materials, shortening the production change adjustment time by 70%. This intelligent control method not only solves industry problems such as raw material stratification and uneven mixing, but also simultaneously achieves multiple additional benefits such as extended equipment life, flexible production, and environmental friendliness. For example, the anti-residue design reduces the frequency of manual cleaning and extends the service life of seals. Some container working modes can quickly switch formulas (such as medical film and packaging film), shortening material change time by 70%, etc., providing reliable technical support for the production of high-end protective films.
