Description

Technical Field

[0001] The invention belongs to the field of packaging film processing, and in particular relates to a raw material stirring device used for packaging film processing. Background Art

[0002] Encapsulant film is a material widely used in photovoltaic modules, electronic component protection, and other applications requiring sealing and protection. It primarily protects internal components from external environmental factors (such as moisture, dust, and mechanical damage) while also providing electrical insulation.

[0003] Raw material mixing is a crucial step in the production of encapsulant films. Ensuring uniform mixing of the various raw materials is crucial to the final product's performance. Raw materials include a base resin (such as EVA or POE), a crosslinker, antioxidants, UV absorbers, and other additives. The base resin is in granular form. Mixing aims to uniformly coat the additives throughout the base resin, typically achieved through a stirring device.

[0004] In existing technologies, due to the diverse properties of additives (such as liquid form and unique colors), the degree of mixing during raw material mixing is typically determined by observing the color of the raw material particles. However, after the additives are added to the stirring device, the device must be operated in a vacuum environment to prevent bubbles from forming during adhesion, making it impossible to visually observe the state of the particles. Therefore, existing devices often address mixing issues by setting a sufficient operating time, but this is significantly insufficient for real-time monitoring of the mixing state. To address this issue, a raw material stirring device for encapsulating film processing is proposed to address this issue. Summary of the Invention

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0020] like Figure 1 、 Figure 2 and Figure 4 As shown, a raw material stirring device for packaging film processing provided by one embodiment of the present invention includes a frame 1, a cylinder 2 for receiving raw materials is provided on the frame 1, and further includes: The integrated closed component 3, the top of the cylinder 2 is an open structure, the integrated closed component 3 is located at the top of the cylinder 2, the integrated closed component 3 includes a cover 301 that matches the cylinder 2, the cover 301 is provided with an agitator 302 facing the inside of the cylinder 2, and the cover 301 is fixedly connected to a vacuum actuator 303.

[0021] The lifting control component 4 is located on both sides of the outside of the cylinder 2. The output end of the lifting control component 4 is connected to the cover 301, which is used to drive the cover 301 to move in the vertical direction. When the cover 301 and the cylinder 2 are in a closed state, the vacuum actuator 303 is used to extract the air in the cylinder 2. A group of heating coils 6 are provided on the outside of the cylinder 2. The vacuum actuator 303 can be in the form of a vacuum pump or an air compressor pump, and the function of the heating coil 6 is to volatilize the moisture in the additive, reduce the viscosity between the raw material particles, and solve the problem of adhesion.

[0022] The material discharge component 5 is located at the bottom of the cylinder 2 and is used to discharge the stirred raw materials in the cylinder 2.

[0023] In one embodiment of the present invention, the encapsulating film raw material stirring device of the present invention effectively solves the problem of difficulty in observing the raw material state due to the vacuum environment during traditional stirring processes through the coordinated design of an integrated sealing component 3 and a vacuum actuator 303. At the same time, the flexible opening and closing of the lid 301 is achieved through the lifting control component 4, taking into account both the sealing performance and operational convenience of the mixing process. In addition, the heating coil 6 can control the stirring temperature within the barrel 2, allowing the moisture in the liquid additive to evaporate quickly, solving the problem of raw materials easily sticking together during stirring. The device also reduces residual bubbles by creating a vacuum environment. Combined with real-time temperature control, it further optimizes the adhesion effect between the base resin and the additive, avoiding the risk of uneven mixing caused by traditional reliance on time settings. The modular structural design facilitates cleaning and maintenance, reduces production costs, and overall improves the intelligent level and process reliability of encapsulating film production.

[0024] In one embodiment of the present invention, Figure 3 As shown, the lifting control assembly 4 includes a hydraulic base 401 fixedly connected to the outside of the cylinder 2, the output end of the hydraulic base 401 is a telescopic rod 402 located at the top of the hydraulic base 401, and the number of the telescopic rods 402 is two. The tops of the two telescopic rods 402 are fixedly connected with ear plates 403 for connecting to the sides of the cover 301. The hydraulic base 401 drives the cover 301 to rise and fall through the telescopic rods 402 that can be telescoped in the vertical direction, so that the cover 301 is separated from or in contact with the cylinder 2, as shown in FIG. Figure 8 As shown, a gas sealing ring 12 is provided at the joint between the cylinder 2 and the cover 301, and an annular groove 13 is provided at the end of the cylinder 2 along the edge of the cylinder 2. The gas sealing ring 12 is located in the annular groove 13. The groove walls on both sides of the annular groove 13 have different heights, and the height of the groove wall close to the inside of the cylinder 2 is less than the height of the groove wall on the other side. The lifting control component 4 adopts a conventional implementation form, and the use of two parallel telescopic rods 402 can ensure the stability of the cover 301 when it is lifted. In addition, since a specially constructed gas sealing ring 12 is provided between the cover 301 and the cylinder 2, the sealing ring in conventional technology will be provided between the cover 301 and the cylinder 2. The aligned end faces, but long-term extrusion deformation and insufficient redundant space will reduce the service life of the gas sealing ring 12, and the groove wall heights on both sides of the annular groove 13 in this device are different. When the cover body 301 and the cylinder body 2 are closed, the gas sealing ring 12 is squeezed and deformed, and at this time the cylinder body 2 is being vacuumed, which can make the gas sealing ring 12 offset inward, thereby completely sealing the contact surface between the cover body 301 and the cylinder body 2. On the basis of giving the gas sealing ring 12 sufficient deformation space, the sealing performance of the cover body 301 and the cylinder body 2 after closing can be guaranteed, so that the inside of the cylinder body 2 quickly reaches a vacuum state, which is conducive to the discharge of bubbles attached to the raw material particles.

[0025] like Figure 4 and Figure 6 As shown, as a preferred embodiment of the present invention, one side of the cylinder 2 is provided with a main feeding component 7 for feeding the main material in the raw materials, and the other side of the cylinder 2 is provided with an auxiliary feeding component 8 for feeding the auxiliary material in the raw materials. When the cover 301 is separated from the cylinder 2 and reaches a predetermined distance, the main feeding component 7 and the auxiliary feeding component 8 are used to add corresponding materials into the cylinder 2.

[0026] In one case of this embodiment, since the cover 301 of the device needs to be lifted and moved, in order to make the vacuum environment in the cylinder 2 easier to achieve, the material feeding structure of the device is not set on the cylinder 2 or the cover 301. In conventional technology, an external device is used to feed the material. When the cover 301 is separated from the cylinder 2, the external device will extend the material feeding pipe into the cylinder 2, and will retract after the feeding is completed. This form undoubtedly makes the raw material mixing process more complicated, so it needs to be improved. The main feeding component 7 includes a fixed connection to the cylinder 2 side of the first mounting block 701, both sides of the first mounting block 701 are rotatably connected to the first connecting rod 702, the other end of the first connecting rod 702 is rotatably connected to the second connecting rod 703 through the shaft, one side of the cover body 301 is fixedly connected to the second mounting block 704, the other end of the second connecting rod 703 is rotatably connected to both sides of the second mounting block 704, and a first dosing pipe 705 is fixedly connected between the two shafts. The auxiliary feeding assembly 8 has the first mounting block 701, the second mounting block 704, the first connecting rod 702, the second connecting rod 703 and the auxiliary feeding assembly 8 arranged in the same manner as the main feeding assembly 7. 3 and the shaft, the second feeding pipe 801 is fixedly connected between the two shafts in the auxiliary feeding assembly 8. When the cover 301 is away from the cylinder 2, the first feeding pipe 705 and the second feeding pipe 801 are both moved into the cylinder 2. After adopting the above structure, the raw material feeding and the lifting and lowering of the cover 301 are combined. When the cover 301 rises, due to the transmission effect of the first connecting rod 702 and the second connecting rod 703, the two will pull the first feeding pipe 705 and the second feeding pipe 801 to move into the cylinder 2, so that material feeding can be carried out. When the cover 301 needs to be closed, the first feeding pipe 705 and The second dosing pipe 801 will move outward to ensure that the two will not affect the closure of the cover 301. This embodiment realizes the adaptive adjustment of the positions of the first dosing pipe 705 and the second dosing pipe 801 through a simple structure. In addition, the first dosing pipe 705 and the second dosing pipe 801 are both connected to the corresponding feeding system through the hose 9, and the first dosing pipe 705 and the second dosing pipe 801 are kept in a tilted state toward the inside of the cylinder 2 by suspending the hose 9, ensuring that the main material and auxiliary material can enter the cylinder 2 more smoothly. The main material and auxiliary material correspond to the base resin and the additive, respectively.

[0027] like Figure 4 、 Figure 5 and Figure 7 As shown, as a preferred embodiment of the present invention, the bottom of the cylinder 2 is a conical structure, the material discharge assembly 5 is located at the center of the cylinder 2, and the material discharge assembly 5 includes a mounting frame 501 fixedly connected to the bottom of the cylinder 2, and a material receiving bin 502 corresponding to the center position of the cylinder 2 is fixedly connected to the mounting frame 501, and a discharge pipe 503 is fixedly connected to the bottom of the material receiving bin 502. A discharge port 10 is provided at the bottom of the cylinder 2, and a fitting gate 11 that matches the shape of the bottom of the cylinder 2 is provided at the discharge port 10.

[0028] In one case of this embodiment, the diameter of the material receiving bin 502 is larger than the diameter of the discharge port 10, and the material receiving bin 502 is separated from the fitted gate 11, and the fitted gate 11 is located at the top of the material receiving bin 502, and the fitted gate 11 includes semicircular arc disks 1101 on both sides, and telescopic parts 1102 in a horizontal state are provided on both sides of the bottom of the cylinder 2, and one end of the telescopic part 1102 is fixedly connected to the semicircular arc disk 1101, and the telescopic part 1102 is used to drive the semicircular arc disks 1101 on both sides to move toward each other. When the two semicircular arc disks 1101 are engaged, the overall structure composed of the two semicircular arc disks 1101 is consistent with the structural shape of the bottom of the cylinder 2. Generally speaking, conventional stirring devices use valves to control the discharge of raw materials. Such valves are arranged at the bottom of the pipeline or the cylinder 2, and the valve itself has a certain space inside. When the raw materials are discharged, the valve 1101 is opened. After the material is added to the cylinder 2, a small part of the particles will enter the valve. When the agitator 302 stirs and mixes in the cylinder 2, this part of the particles is difficult to mix with the additives. When the above structure is adopted, after the two semicircular arc disks 1101 are closed, the bottom of the cylinder 2 as a whole will present a complete conical structure, and all the raw materials will be present in the cylinder 2. In this way, all the raw material particles can be mixed with the additives, and there will be no so-called residual problem. This small part of the raw materials cannot be mixed. It is a very critical factor for the production of packaging film, and the present device avoids this problem. When the two semicircular arc disks 1101 are opened, the raw material particles in the cylinder 2 will fall into the receiving bin 502 from the discharge port 10, so that the raw material particles will be discharged from the discharge pipe 503. The telescopic part 1102 can be in the form of electric telescopic movement, and of course it can also be controlled by hydraulic pressure.
