[0041] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0042] like Figures 1 to 13 As shown, a composite pressing roller device includes a base 1, an ozone component 2 located on the base 1 and spraying ozone gas toward a substrate, a cooling roller 3 rotatably connected to the base 1 at both ends for compounding a liquid film formed by heating and melting plastic particles with a substrate, a composite roller 4 and a back pressure roller 5 movably arranged on the right side of the cooling roller 3, the back pressure roller 5 cooperates with the composite roller 4 to press the substrate onto the cooling roller 3 and cooperates with the cooling roller 3 to compound the substrate and the plastic film, an adjustment component 6 is arranged between the back pressure roller 5 and the composite roller 4, the adjustment component 6 is used to control the pressure applied by the back pressure roller 5 on the cooling roller 3, and the adjustment component 6 includes a pair of guide members 600 arranged on both ends of the composite roller 4 and the cooling roller 3, and the guide member 600 is provided with a Track groove 601, the back pressure roller 5 is fixedly connected to the right end of the guide member 600, and the end of the composite roller 4 is provided with a first connecting part 401 connected to the ozone assembly 2. The first connecting part 401 is slidably connected in the track groove 601 to control the pressure applied by the composite roller 4 to the cooling roller 3. The first connecting part 401 has a first position and a second position in the track groove 601. The back pressure roller 5 can drive the guide member 600 to make the first connecting part 401 switch between the first position and the second position; when the first connecting part 401 is in the first position, the back pressure roller 5 presses against the composite roller 4 to press the composite roller 4 against the cooling roller 3; when the first connecting part 401 is in the second position, there is a gap between the back pressure roller 5 and the composite roller 4, and between the composite roller 4 and the cooling roller 3.

[0043] The device includes a base 1, an ozone component 2, a cooling roller 3, a compound roller 4 and a back pressure roller 5; specifically, the ozone component 2 is located on the base 1 and sprays ozone gas toward the substrate for pre-treatment or post-treatment of the substrate surface; the cooling roller 3 is rotatably connected to the base 1 at both ends and is responsible for converting the heated and melted plastic particles into a liquid film and compounding it with the substrate; the compound roller 4 is movably arranged on the right side of the cooling roller 3, and the back pressure roller 5 works in conjunction with the compound roller 4 to ensure that the substrate is accurately pressed onto the cooling roller 3, and the substrate and the plastic film are tightly compounded through the cooling roller 3. In this embodiment, in order to achieve precise control of the pressure during the compounding process, an adjustment component 6 is specially arranged between the back pressure roller 5 and the compound roller 4. The main function of the adjustment component 6 is to control the pressure applied by the back pressure roller 5 to the cooling roller 3 to ensure stability and quality consistency during the compounding process. The adjustment component 6 is composed of a pair of guide members 600, which are respectively installed at the two ends of the compound roller 4 and the cooling roller 3, and have tracks along their length. Groove 601, the back pressure roller 5 is fixedly connected to the right end of the guide member 600, and the end of the composite roller 4 is provided with a first connecting part 401, which is slidably connected to the track groove 601 of the guide member 600, so that the pressure applied by the composite roller 4 to the cooling roller 3 can be adjusted as needed. The first connecting part 401 has two key positions in the track groove 601: the first position and the second position. When the first connecting part 401 is in the first position, the back pressure roller 5 will press against the composite roller 4, so that the composite roller 4 is tightly pressed against the cooling roller 3, ensuring a good composite effect; on the contrary, when the first connecting part 401 moves to the second position, a certain gap will be generated between the back pressure roller 5 and the composite roller 4, and between the composite roller 4 and the cooling roller 3, which provides convenient conditions for equipment maintenance, cleaning or material replacement. In this way, the back pressure roller 5 can drive the guide member 600, so that the first connecting part 401 can be flexibly converted between the two positions, realizing fine regulation of the composite pressure and improving the automation level and efficiency of the entire composite process.

[0044] In addition, the ozone component 2 can not only participate in the above-mentioned pressure regulation mechanism around the first connection part 401, but also integrate the spraying function of ozone gas, further enhancing the versatility and integration of the system, reducing the number of components, and also improving the convenience of operation and the reliability of the system.

[0045] Specifically, Figures 1 to 9 As shown, both ends of the back pressure roller 5 are back pressure roller supporting ends 500, a second connecting portion 501 is provided on the inner end surface of the back pressure roller supporting end 500, a connecting hole 602 is provided on the guide member 600 on the right side of the track groove 601, and the second connecting portion 501 passes through the connecting hole 602 and is fixedly connected by a nut.

[0046] The two ends of the back pressure roller 5 are provided with back pressure roller supporting ends 500, and the inner end surface of each supporting end is provided with a second connecting portion 501. Specifically, the guide member 600 is located at both ends of the cooling roller 3 and the composite roller 4, and a connecting hole 602 is provided on the right side of its track groove 601. The second connecting portion 501 on the back pressure roller supporting end 500 is precisely penetrated into the connecting hole 602 of the guide member 600 and fixedly connected by a nut. This structural design not only ensures a firm connection between the back pressure roller 5 and the guide member 600, but also allows the back pressure roller 5 to slide along the guide member 600 as needed to adjust its position relative to the composite roller 4. In this way, the back pressure roller 5 can flexibly respond to the instructions of the adjustment component 6 to achieve precise control of the pressure during the composite process, while ensuring the stability of the entire system.

[0047] Furthermore, if Figures 7 to 9 As shown, a limiting member 502 is provided on the back pressure roller supporting end 500, and the length direction of the limiting member 502 is parallel to the length direction of the guide member 600. Both ends of the composite roller 4 are composite roller supporting ends 400. The right side of the limiting member 502 is threadedly connected to the left side of the back pressure roller supporting end 500, and the left side of the limiting member 502 is movably abutted against the composite roller supporting end 400 at the same end; when the first connecting portion 401 is in the first position, the left side of the limiting member 502 abuts against the composite roller supporting end 400; when the first connecting portion 401 is in the second position, the left side of the limiting member 502 is away from the composite roller supporting end 400.

[0048] The back pressure roller support end 500 is not only matched with the connecting hole 602 on the guide member 600 through the second connecting part 501 and fixedly connected through a nut, but also a limiter 502 is arranged thereon, and the length direction of the limiter 502 is parallel to the length direction of the guide member 600, ensuring the consistency and stability of the structure. The two ends of the composite roller 4 are respectively designed as composite roller support ends 400, and the right side of the limiter 502 is threadedly connected to the left side of the back pressure roller support end 500, while the left side of the limiter 502 is movably abutted against the composite roller support end 400 at the same end. This design cleverly realizes precise control of the position and pressure during the composite process: when the first connecting part 401 When in the first position, the left side of the limit member 502 tightly abuts against the composite roller supporting end 400, so that the back pressure roller 5 can firmly press the composite roller 4 against the cooling roller 3, ensuring a good composite effect; on the contrary, when the first connecting part 401 moves to the second position, a gap is generated between the left side of the limit member 502 and the composite roller supporting end 400, so that there is a certain space between the back pressure roller 5, the composite roller 4 and the cooling roller 3. The limit member 502 not only limits the relative movement of the back pressure roller 5 and the composite roller 4, but also enhances the stability and reliability of the entire system. At the same time, the threaded connection design facilitates disassembly and adjustment, thereby improving the operation convenience and service life of the equipment.

[0049] Furthermore, if Figures 4 to 9 As shown, the adjustment component 6 also includes a pair of driving cylinders 603 respectively arranged on the left and right ends of the base 1, a pair of guide rails 604 obliquely connected to the left and right ends of the base 1, and a plurality of sliders 605 slidably connected to the guide rails 604. The guide member 600 and the driving cylinder 603 are both arranged parallel to the guide rails 604. The driving end of the driving cylinder 603 is connected to the back pressure roller support end 500, and the bottoms of the back pressure roller support end 500 and the compound roller support end 400 are both installed on the slider 605.

[0050] A pair of driving cylinders 603, a pair of inclined guide rails 604, and a plurality of sliders 605 slidably connected to the guide rails 604 are respectively arranged at the left and right ends of the base 1. The guide member 600 and the driving cylinder 603 are arranged in parallel with the guide rails 604 to ensure the overall coordination and stability of the structure. The driving end of the driving cylinder 603 is directly connected to the back pressure roller support end 500, while the bottom of the back pressure roller support end 500 and the composite roller support end 400 are installed on the slider 605. The position adjustment is achieved by sliding the slider 605 along the guide rail 604. This design allows the driving cylinder 603 to accurately control the position of the back pressure roller support end 500, thereby achieving a smooth and stable operation. The relative distance and pressure between the back pressure roller 5 and the composite roller 4 are affected. When the driving cylinder 603 is working, it can push or pull the back pressure roller support end 500, so that the back pressure roller 5 slides along the guide member 600, and drives the first connecting part 401 to move in the track groove 601, thereby changing its pressure application state relative to the cooling roller 3. The sliding of the slider 605 on the guide rail 604 ensures the stability and accuracy of the entire movement process and avoids unnecessary vibration or deviation. In addition, the inclined setting of the guide rail 604 not only provides additional operating space for the equipment, but also optimizes the force transmission path, thereby improving the response speed and efficiency of the system.

[0051] Specifically, Figure 1 and Fig.12 At least one spiral flow channel 503 is arranged inside the back pressure roller 5 along its axial direction, and cooling water pipes 504 and rotating joints 505 connecting the back pressure roller 5 and the cooling water pipes 504 are arranged at both ends of the back pressure roller 5. The spiral flow channel 503 is connected to the cooling water pipe 504 through the rotating joint 505.

[0052] At least one spiral flow channel 503 is arranged inside the back pressure roller 5 along its axial direction for guiding the circulation of cooling water. Cooling water pipes 504 are provided at both ends of the back pressure roller 5, and the back pressure roller 5 is connected to the cooling water pipe 504 through a rotating joint 505, thereby ensuring effective communication between the spiral flow channel 503 and the cooling water pipe 504, not only realizing the circulation of cooling water inside the back pressure roller 5, but also ensuring a stable supply of cooling water even when the back pressure roller 5 is rotating, thereby effectively reducing the working temperature of the back pressure roller 5. The cooling water enters from the cooling water pipe 504 at one end, enters the spiral flow channel 503 inside the back pressure roller 5 through the rotating joint 505, circulates in the spiral flow channel 503 along the axial direction of the back pressure roller 5, and is discharged from the cooling water pipe 504 at the other end after absorbing heat.

[0053] Specifically, Figures 2 to 10 As shown, the ozone assembly 2 includes an ozone tube 200 arranged along the width direction of the base 1 for spraying ozone gas, a pair of driving cylinders 201 respectively arranged on the inner ends of the two composite roller support ends 400, and a swing arm 202 that drives the ozone tube 200 to swing around the first connecting part 401 above the composite roller 4 through the drive of the driving cylinder 201.

[0054] The ozone assembly 2 specifically includes an ozone tube 200 arranged along the width direction of the base 1 for accurately spraying ozone gas; in addition, it is also equipped with a pair of driving cylinders 201, which are respectively installed on the inner ends of the two composite roller support ends 400. Through the driving action of the pair of driving cylinders 201, a swing arm 202 is driven to move, so that the ozone tube 200 can swing flexibly around the first connecting portion 401 above the composite roller 4. The ozone tube 200 is horizontally arranged along the width direction of the base 1 to ensure that the ozone gas can evenly cover the entire composite area. The driving cylinder 201 is installed on the inner side of the composite roller support end 400, and its driving end is connected to the swing arm 202, and the swing arm 202 is connected to the ozone tube. 200 is fixedly connected. When the driving cylinder 201 is working, it can push or pull the swing arm 202, so that the ozone tube 200 can swing up and down above the composite roller 4. The spraying angle and range of the ozone gas can be adjusted according to actual needs, and it can also ensure that a uniform ozone treatment effect can be obtained at different positions. The design of the swing arm 202 cleverly uses the first connecting part 401 as the rotation center, so that the ozone tube 200 can be accurately positioned and moved above the composite roller 4. This mechanism ensures that the ozone gas can be accurately sprayed to the target area, thereby improving the treatment efficiency and quality. At the same time, the application of the driving cylinder 201 realizes the automatic control of the swing of the ozone tube 200.

[0055] Furthermore, if Figure 2 , Fig.10 and Fig.11As shown, ozone tube bases 203 connected to the swing arm 202 are provided at both ends of the ozone tube 200 , and a plurality of nozzles 204 are installed on the ozone tube 200 , and the plurality of nozzles 204 are distributed between the two ozone tube bases 203 along the length direction of the ozone tube 200 .

[0056] Ozone tube holders 203 connected to the swing arm 202 are provided at both ends of the ozone tube 200, ensuring that the ozone tube 200 can be swung stably and flexibly above the composite roller 4. The ozone tube 200 itself is equipped with a plurality of nozzles 204, which are evenly distributed between the two ozone tube holders 203 along the length direction of the ozone tube 200, ensuring that the ozone gas can evenly and widely cover the entire processing area. The ozone tube holder 203 serves as a connecting piece, one end of which is firmly fixed to both ends of the ozone tube 200, and the other end is connected to the swing arm 202. This design not only ensures the stability of the ozone tube 200 during the swinging process, but also allows the precise control of its swinging angle and position by driving the cylinder 201. The multiple nozzles 204 on the ozone tube 200 are arranged at a predetermined interval to ensure that the ozone gas is evenly sprayed from the tube body, so that the substrate surface can be fully covered and evenly treated both in the initial position and during the swinging process. The design of the nozzle 204 takes into account the optimization of the spraying angle and flow rate to meet different process requirements and provide the best ozone treatment effect.

[0057] Furthermore, if Figures 8 to 10 As shown, the swing arm 202 includes a first assembly portion 205 connected to the ozone tube seat 203, a second assembly portion 206 rotatably connected to the first connection portion 401, and a third assembly portion 207 adjacent to the second assembly portion 206 for connecting to the driving end of the driving cylinder 201, wherein the first assembly portion 205 is located at the upper end of the swing arm 202, the second assembly portion 206 is located at the lower end of the swing arm 202, an arc portion matching the outer wall of the composite roller 4 is formed between the first assembly portion 205 and the second assembly portion 206, and an angle is formed between the third assembly portion 207 and the second assembly portion 206.

[0058] The swing arm 202 is uniquely designed and includes three key parts: a first assembly portion 205 located at the upper end of the swing arm 202, a second assembly portion 206 located at the lower end and rotatably connected to the first connecting portion 401, and a third assembly portion 207 adjacent to the second assembly portion 206 and used to connect to the driving end of the driving cylinder 201. In this embodiment, the first assembly portion 205 is provided with a structure connected to the ozone tube holder 203, ensuring that the ozone tube 200 can be firmly installed on the swing arm 202; the second assembly portion 206 cooperates with the first connecting portion 401 by a rotatable connection, allowing the swing arm 202 to swing flexibly around the first connecting portion 401; the third assembly portion 207 is connected to the driving end of the driving cylinder 201, and the swing arm 202 is controlled by the action of the driving cylinder 201. 02, an arc-shaped portion matching the outer wall of the composite roller 4 is formed between the first assembly portion 205 and the second assembly portion 206. This design not only ensures that the swing arm 202 will not interfere with the composite roller 4 during the swinging process, but also makes the entire device more compact and harmonious. In addition, a specific angle formed between the third assembly portion 207 and the second assembly portion 206 optimizes the force transmission path and ensures that the driving cylinder 201 can efficiently transmit power to the swing arm 202, thereby realizing precise swing control of the ozone tube 200. Under the action of the driving cylinder 201, the swing arm 202 can drive the ozone tube 200 to swing flexibly and stably around the first connecting portion 401 above the composite roller 4, ensuring that the ozone gas can be evenly sprayed to the target area.

[0059] Furthermore, if Figures 8 to 10 As shown, the inner end of the back pressure roller support end 500 is provided with a third connection portion 402, the driving cylinder 201 is connected to the third connection portion 402, and the driving cylinder 201 and the guide rail 604 are staggered in space and form an angle.

[0060] The inner end of the back pressure roller support end 500 is provided with a third connection part 402, and the third connection part 402 serves as a connection point of the driving cylinder 201, ensuring that the driving cylinder 201 can be firmly and accurately connected to the back pressure roller support end 500. The driving cylinder 201 is connected to the third connection part 402 through its driving end, realizing accurate control of the position and movement of the back pressure roller 5. It is worth mentioning that, as Figure 4 and Figure 8As shown in the figure, the driving cylinder 201 and the guide rail 604 are staggered in space and form a specific angle. This design optimizes the force transmission path, ensures that the driving cylinder 201 can efficiently transmit power to the back pressure roller support end 500, and avoids interference between the two. The third connecting part 402 provides the fixing point required for the installation of the driving cylinder 201, so that the driving cylinder 201 can remain stable during operation, ensuring the accuracy and reliability of its movement. The staggered arrangement between the driving cylinder 201 and the guide rail 604 not only provides additional operating space for the equipment, but also enhances the flexibility and adaptability of the system.
