Description

Technical Field

[0001] The invention relates to the technical field of film laminating machines, and in particular discloses a heating and quick-cooling film laminating machine for pearl cotton rolls. Background Art

[0002] In the field of coating processing of pearl cotton coils, traditional coating equipment usually has a single function and each link is independent of each other. The steps of unwinding, heating, coating, cooling, winding and slitting are often operated by different equipment respectively. The coils need to be frequently handled and adjusted during the production process, which not only increases the time and labor costs of the intermediate links, but also reduces production efficiency. In terms of coating quality, the previous heating method may have the problem of uneven heating, resulting in inconsistent heating of the pearl cotton coil and the coating material, affecting the fit of the coating. At the same time, the pressure of the coating device is insufficient or unstable, which easily causes defects such as bubbles and wrinkles in the coating, and the cooling effect is poor, and it cannot be finalized in time, making it difficult to guarantee the coating quality.

[0003] In terms of operational convenience and adaptability, the various parts of traditional equipment have relatively fixed structures and lack flexible adjustment mechanisms. This makes it difficult to adjust the width and thickness of pearl cotton rolls of different specifications, and the versatility is poor. Operators also face problems such as complex operations and high labor intensity during use, which cannot meet the needs of modern efficient production. Summary of the invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a heating and rapid cooling laminating machine for pearl cotton rolls.

[0005] To achieve the above-mentioned purpose, the present invention provides a heating and rapid cooling laminating machine for pearl cotton coils, comprising a frame, a unwinding device, a winding device, a heating device, a laminating device and a cooling device arranged on the frame; the cooling device is below the laminating device, and the laminating device is below the heating device. The unwinding device has an unwinding roller and a film material roller rotatably arranged on the frame, the laminating device has a film coating roller rotatably arranged on the frame, the winding device has a winding roller rotatably arranged on the frame, the heating device has a heating roller rotatably arranged on the frame, and the cooling device has a cooling plate arranged on the frame; the pearl cotton coil is unwound by the unwinding roller, and the laminating coil is unwound by the film material roller. The pearl cotton coil and the laminating coil are heated by the heating roller and then squeezed by the laminating roller for laminating, and the laminating pearl cotton coil is cooled by the cooling plate and then rolled up by the winding roller.

[0006] The film roll is unwound and attached to the heating roller for uniform heating, so that the viscosity of the film roll surface can be evenly distributed. This ensures that during the film lamination process, the film material can be fully and evenly fitted with the pearl cotton roll, avoiding problems such as loose fitting or bubbles caused by insufficient or excessive local viscosity, thereby significantly improving the quality and integrity of the film. The cooling medium is sprayed on the pearl cotton roll after filming through the cooling holes on the cooling plate for rapid cooling, which can quickly solidify the film material. This rapid solidification helps to enhance the adhesion between the film and the pearl cotton, making it difficult to separate during subsequent processing and use, and further improving the stability and reliability of the film. The rotation setting of the heating roller can ensure that the pearl cotton roll and the film roll are evenly heated, avoiding local overheating or insufficient heating, creating good temperature conditions for the film, and improving the fit and firmness of the film. The film roller squeezes the heated pearl cotton roll and the film roll to make the film more compact and smooth, reduce the generation of bubbles and wrinkles, and improve the quality of the film. The cooling plate quickly cools the EPE coil after lamination, which helps the material to be quickly shaped after lamination, and maintains a good lamination shape and appearance quality. The unwinding roller, winding roller, heating roller and laminating roller are rotatably set on the frame, making the conveying of the coil more stable and smooth, easy to operate, reducing the need for manual intervention and reducing labor intensity.

[0007] Furthermore, a heating drive mechanism for driving the heating roller to rotate is provided on the frame, and a left end shaft head and a right end shaft head are provided at both ends of the heating roller, respectively. The shaft core of the left end shaft head is provided with an oil inlet pipeline, and the shaft core of the right end shaft head is provided with an oil outlet pipeline. A circulation pipeline is provided in the heating roller to connect the oil inlet pipeline and the oil outlet pipeline, and the number of the circulation pipelines is set to be multiple. The multiple circulation pipelines are arranged around the rotation axis of the heating roller, and two heaters for heating the heating roller are provided on the frame, and the two heaters are respectively connected to the oil inlet pipeline and the oil outlet pipeline.

[0008] By setting a circulation pipeline inside the heating roller and using the oil inlet pipeline of the left end shaft head and the oil outlet pipeline of the right end shaft head to form a circulation loop, the heating medium (such as the heating medium) can flow evenly inside the heating roller, thereby achieving uniform heating of the heating roller. In conjunction with the heater on the frame, the temperature of the heating roller can be controlled more accurately. Multiple circulation pipelines increase the contact area between the heating medium and the inner wall of the heating roller, and improve the heat conduction efficiency. The heating medium can transfer heat to the heating roller more quickly, thereby shortening the heating time and improving production efficiency. The internal circulation heating method makes the contact area between the heating medium and the heating roller larger and the heat transfer efficiency higher. Since the heating medium circulates inside the heating roller, the temperature of the heating roller can be effectively kept stable and the heat loss can be reduced.

[0009] Furthermore, the number of cooling plates is set to multiple, and the multiple cooling plates are arranged in parallel on both sides of the pearl cotton roll after coating. The number of cooling holes is set to multiple, and a cooling cavity is provided in the cooling plate to communicate with an external refrigerator. The cooling hole is connected to the cooling cavity and is semi-elliptical in the direction from the cooling cavity to the outside of the cooling plate, and the long axis direction of the semi-ellipse is consistent with the feeding direction of the roll.

[0010] The multiple cooling holes on the cooling plate are connected to the cooling cavity, so that the cooling medium (such as cold air) can be more evenly distributed on the surface of the cooling plate, fully contacting with the pearl cotton coil, further improving the cooling effect. The cooling hole is elliptical in the direction from the cooling cavity to the outside of the cooling plate, and the long axis direction of the ellipse is consistent with the feeding direction of the coil. This design enables the cooling medium to be directionally cooled along the feeding direction of the pearl cotton coil, matching the movement direction of the coil, and improving the pertinence and effectiveness of the cooling. Directional cooling can reduce the generation of cooling dead corners, ensure that all parts of the pearl cotton coil can be fully cooled, and thus improve the stability of the coating quality. The parallel arrangement of multiple cooling plates and the uniform distribution of cooling holes enable the cooling medium to act evenly on both sides of the pearl cotton coil, ensuring the uniformity of cooling. This helps to avoid deformation, warping and other problems of the pearl cotton coil due to uneven local cooling, and improves the quality of the product.

[0011] Furthermore, the laminating device has a laminating driving mechanism for driving the laminating roller to rotate, and a laminating adjusting mechanism for adjusting the distance between the laminating roller and the coil. The number of laminating rollers is set to be multiple, and the multiple laminating rollers are arranged in parallel on both sides of the pearl cotton coil released by the unwinding roller. The surface of the laminating roller is provided with a plurality of arranged concave holes.

[0012] The laminating drive mechanism ensures that the laminating roller can rotate stably and provides reliable power for the laminating process. The laminating adjustment mechanism can accurately adjust the distance between the laminating roller and the coil, so as to adapt to different thicknesses of EPE coils and laminating materials. Fine-tuning can be performed according to actual conditions to ensure that the pressure and fit of the laminating are in the best state and improve the laminating quality. Laminating the EPE coil from both sides of the coil feeding direction increases the contact area and uniformity of the laminating. The joint action of multiple laminating rollers can make the laminating more compact and smooth, and reduce the generation of bubbles and wrinkles. Several arranged concave holes on the surface of the laminating roller can increase the friction between the laminating roller and the laminating material, prevent the laminating material from sliding during the laminating process, and ensure the accuracy and stability of the laminating. At the same time, the concave holes can also make the laminating material better fit on the surface of the EPE coil, improving the firmness of the laminating.

[0013] Furthermore, the frame is provided with a first accommodating opening for accommodating the coating adjustment mechanism, the first accommodating opening is provided with a coating adjustment motor and a first guide rail, the output shaft of the coating adjustment motor is provided with a first screw, the other end of the first screw is rotatably provided on the first accommodating opening, the first screw is rotatably provided with a first bearing seat, the coating roller is rotatably connected to the first bearing seat, the first bearing seat is provided with a first slider, and the first slider and the first guide rail are slidably connected.

[0014] The use of the laminating adjustment motor makes the distance adjustment between the laminating roller and the coil more accurate and automatic. By controlling the speed and direction of the laminating adjustment motor, the position of the laminating roller can be finely adjusted to meet the laminating requirements of materials of different thicknesses and improve the stability of the laminating quality. As a transmission component, the first screw has the characteristics of high transmission accuracy and good stability. It can convert the rotational motion of the laminating adjustment motor into linear motion, accurately control the position of the first bearing seat, thereby driving the laminating roller to move, ensuring that the distance between the laminating roller and the coil is always in the best state. The laminating roller is rotatably connected to the first bearing seat through a bearing. This connection method ensures the smooth rotation and reliability of the laminating roller.

[0015] Furthermore, the unwinding device has an unwinding drive mechanism for driving the unwinding roller to rotate and a film material drive mechanism for driving the film material roller to rotate. Adjustable stop plates are provided at both ends of the unwinding roller. The stop plate has a stop portion for resisting and stopping the pearl cotton roll material and a fixed portion connected to the unwinding roller. A plurality of adjusting springs are provided between the stop portion and the fixed portion for adjusting the distance between the stop portion and the pearl cotton roll material. The plurality of adjusting springs are arranged around the rotation axis of the unwinding roller.

[0016] The stopper can resist and stop the pearl cotton coil material, preventing the coil material from being too loose or offset during the unwinding process. This helps to maintain the stable unwinding of the coil material and ensure the continuity and uniformity of the unwinding. The setting of the adjustment spring enables the stopper to automatically adjust the distance between the pearl cotton coil material and the pearl cotton coil material according to the change in the diameter of the coil material. As the coil material is gradually released, the diameter decreases, and the adjustment spring can push the stopper to always maintain proper contact with the coil material to ensure the stopping effect. The adjustment spring acts as a buffer between the stopper and the coil material. When the coil material is impacted or vibrated by external force, the adjustment spring can absorb part of the energy, reduce the direct impact force on the coil material, and thus protect the coil material from damage. If there is no adjustment spring, the stopper may directly and hard contact with the coil material, which may easily cause surface damage or deformation of the coil material. The existence of the adjustment spring makes the contact between the stopper and the coil material softer, reducing the risk of damage to the coil material.

[0017] Furthermore, the winding device has a winding drive mechanism for driving the winding roller to rotate, a material receiving trolley for transferring the coiled material wound by the winding roller, and a lifting mechanism arranged on the material receiving trolley; a pair of clamping arms for clamping the coiled material wound by the winding roller are rotatably provided on the lifting mechanism, and both clamping arms are provided with power components for rotating the clamping arms to clamp the coiled material, and the clamping surfaces of the two clamping arms for clamping the coiled material are both arc-shaped, and a protective layer is provided on both clamping surfaces to protect the coiled material from being worn and damaged by the clamping surfaces.

[0018] The winding drive mechanism ensures that the winding roller can rotate stably and realizes the efficient winding of the coated pearl cotton coil. The speed of the winding roller can be accurately controlled according to the production speed requirements to ensure the continuity and stability of the winding process. The lifting mechanism enables the winding roller to be automatically raised and lowered, which is convenient for operators to replace and install the coil. During the winding process, the height of the winding roller can be automatically adjusted according to the thickness of the coil to ensure the neatness and tightness of the winding. The material collection vehicle is convenient for transferring the coil wound by the winding roller, which improves the automation degree and work efficiency of production. A pair of clamping arms on the material collection vehicle can firmly clamp the coil wound by the winding roller to prevent the coil from loosening or falling during the transfer process. The power assembly provides clamping force for the clamping arm to ensure the stability and reliability of the clamping. The clamping surface of the clamping arm is arc-shaped, which matches the shape of the winding roller, can better fit the coil, increase the contact area of ​​the clamping, and improve the stability of the clamping. At the same time, the arc-shaped clamping surface also helps to reduce the local pressure on the coil and prevent the coil from deforming. The protective layer on the two clamping surfaces can effectively protect the coil from being damaged by the clamping surfaces. The protective layer is usually made of soft, wear-resistant materials, such as rubber, plastic, etc., which can play a buffering and protective role during the clamping process to ensure that the surface quality of the coil is not affected.

[0019] Furthermore, the heating and rapid cooling laminating machine for pearl cotton coils also includes a tension regulating device, which has a tension sensor arranged on a roller for sensing the tension of the coil feeding process, a magnetic powder brake is arranged at one end of the roller, the magnetic powder brake has an inner rotor and an outer rotor, the inner rotor is provided with a magnetic powder driver, the outer rotor is cooperatively connected to the roller, a gap for accommodating magnetic powder is provided between the inner rotor and the outer rotor, an excitation coil is provided on the outer rotor and connected to an external power supply, the power supply controls the current flowing into the excitation coil to make the magnetic powder form a magnetic chain to link the inner and outer rotors to adjust the torque between the inner and outer rotors, and the feeding speed of the coil is controlled by the torque so that the feeding tension of the coil is adjusted.

[0020] The tension sensor can sense the tension during the coil feeding process in real time and provide accurate data feedback for tension adjustment. By accurately monitoring the tension changes, abnormal tension can be discovered in time so that adjustments can be made quickly to ensure that the tension of the coil is always kept within the appropriate range during the lamination process. The power supply controls the current flowing into the excitation coil so that the magnetic powder forms a magnetic chain to link the inner and outer rotors, thereby adjusting the torque between the inner and outer rotors. This adjustment method is very accurate. The torque can be accurately adjusted according to the feedback signal of the tension sensor, thereby realizing fine adjustment of the coil feeding tension. Stable feeding tension can ensure that the pearl cotton coil and the laminating coil always maintain a good fit during the laminating process, reduce the generation of defects such as bubbles and wrinkles, and improve the laminating quality. The tension adjustment device can adjust the appropriate tension parameters according to pearl cotton coils of different materials and thicknesses and different laminating process requirements.

[0021] Furthermore, the heating and quick-cooling laminating machine for pearl cotton rolls also includes a guiding device rotatably arranged on a frame, the guiding device is arranged between the unwinding device and the winding device, the guiding device has a first guide roller and a second guide roller for cooperating with the unwinding of the pearl cotton roll, a third guide roller for cooperating with the unwinding of the laminating roll, and a fourth winding roller and a fifth winding roller for cooperating with the winding roller for winding. A guiding adjustment component cooperating with the guide roller is also arranged on the frame, and the guiding adjustment component adjusts the position of the guide roller relative to the frame to change the wrap angle between the roll and the guide roller to adjust the tension of the roll feeding.

[0022] The multiple guide rollers in the guide device can accurately guide the pearl cotton coil during the heating, coating, cooling and winding process, ensuring that the coil is stably conveyed along the predetermined path, reducing the deviation and distortion of the coil, and improving the accuracy and quality of the coating. By adjusting the position of the guide roller through the guide adjustment component, the wrap angle between the coil and the guide roller can be changed, thereby adjusting the tension of the coil feeding. This adjustment method is simple and effective, and can flexibly adjust the tension according to actual production needs to ensure the stability of the tension of the coil in each link. For pearl cotton coils of different widths and thicknesses and coated coils, the guide device and the guide adjustment component can be adjusted accordingly to meet the conveying and tension requirements of coils of different specifications, thereby improving the versatility and adaptability of the equipment.

[0023] Furthermore, the heating and quick-cooling laminating machine for pearl cotton rolls also includes a slitting device arranged on the frame, the slitting device is arranged between the cooling device and the winding device for slitting the pearl cotton rolls after lamination, the slitting device has a slitting bracket arranged on the frame, and the slitting bracket is provided with a plurality of retractable cutters, and the cutters are detachably connected to the slitting bracket.

[0024] The cutter in the slitting device is retractable, and the extension length of the cutter can be adjusted according to different slitting requirements. This allows the equipment to adapt to the slitting requirements of pearl cotton rolls of different widths, improving the flexibility and versatility of the equipment. There are multiple cutters on the slitting bracket, which can perform multiple slitting on the pearl cotton rolls after coating at the same time, improving the slitting efficiency. The positions of multiple cutters can be precisely adjusted as needed to ensure the accuracy and consistency of the slitting size. The slitting device is set between the cooling device and the winding device, and can be slitting immediately after the pearl cotton roll is coated, realizing the online slitting function.

[0028] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0029] See also Figures 1 to 9As shown, a heating and rapid cooling laminating machine for pearl cotton coils of the present invention comprises a frame 1, an unwinding device 2, a winding device 3, a heating device 4, a laminating device 5 and a cooling device 6 arranged on the frame 1; the unwinding device 2 comprises an unwinding roller 21 and a film material roller 22 rotatably arranged on the frame 1, the laminating device 5 comprises a laminating roller 51 rotatably arranged on the frame 1, the winding device 3 comprises a winding roller 31 rotatably arranged on the frame 1, the heating device 4 comprises a heating roller 41 rotatably arranged on the frame 1, and the cooling device 6 comprises a cooling plate 61 arranged on the frame 1; the film coil is unwound and attached to the heating roller 41 for uniform heating, the surface of the heated film coil is sticky, the film roller 51 squeezes the heated film coil and adheres it to the pearl cotton coil for lamination, the cooling plate 61 is provided with cooling holes 62 to spray cooling medium on the filmed pearl cotton coil for rapid cooling, and the pearl cotton coil after rapid cooling is wound up via the winding roller 31.

[0030] During actual use, the coated coil is unwound and attached to the heating roller 41 for uniform heating, so that the viscosity of the coated coil surface can be evenly distributed. This ensures that during the coating process, the coating material can be fully and evenly fitted with the pearl cotton coil, avoiding the problems of loose fitting or bubbles caused by insufficient or excessive local viscosity, thereby significantly improving the quality and integrity of the coating. The cooling medium is sprayed on the pearl cotton coil after coating through the cooling holes 62 on the cooling plate 61 for rapid cooling, which can make the coating material solidify rapidly. This rapid solidification helps to enhance the adhesion between the coating and the pearl cotton, making it difficult to separate during subsequent processing and use, and further improving the stability and reliability of the coating. The rotation setting of the heating roller 41 can ensure that the pearl cotton coil and the coating coil are evenly heated, avoiding the situation of local overheating or insufficient heating, creating good temperature conditions for the coating, and improving the fit and firmness of the coating. The coating roller 51 squeezes the heated pearl cotton coil and the coated coil to make the coating tighter and smoother, reduce the generation of bubbles and wrinkles, and improve the quality of the coating. The cooling plate 61 quickly cools the coated pearl cotton coil, which helps the coated material to quickly set and maintain a good coating shape and appearance quality. The unwinding roller 21, the winding roller 31, the heating roller 41 and the coating roller 51 are rotatably arranged on the frame 1, so that the conveying of the coil is more stable and smooth, the operation is convenient, the need for manual intervention is reduced, and the labor intensity is reduced.

[0031] Specifically, a heating drive mechanism 42 for driving the heating roller 41 to rotate is provided on the frame 1, and a left end shaft head 43 and a right end shaft head 44 are respectively provided at both ends of the heating roller 41. The shaft core of the left end shaft head 43 is provided with an oil inlet pipe 45, and the shaft core of the right end shaft head 44 is provided with an oil outlet pipe 46. A circulation pipe 47 is provided in the heating roller 41 for connecting the oil inlet pipe 45 and the oil outlet pipe 46, and the number of the circulation pipes 47 is set to be multiple.

[0032] In this embodiment, the number of circulation pipes 47 is set to be multiple, and the multiple circulation pipes 47 are arranged around the rotation axis of the heating roller 41. Two heaters 48 for heating the heating roller 41 are provided on the frame 1, and the two heaters 48 are respectively connected to the oil inlet pipe 45 and the oil outlet pipe 46.

[0033] In this embodiment, a heating pump 49 is provided on the oil inlet pipeline 45 and the oil outlet pipeline 46 to promote the flow of the heating medium in the circulation pipeline 47. The heating drive mechanism 42 has a heating motor 421 arranged on the frame 1, and a second heating gear 423 arranged on the heating roller 41 and rotating coaxially with the heating roller 41. A first heating gear 422 is provided on the output shaft of the heating motor 421, and the first heating gear 422 and the second heating gear 423 are meshingly connected.

[0034] In actual use, the roller body of the heating roller 41 is made of a material with good thermal conductivity, high heat resistance and sufficient mechanical strength, and the pipe contained in the heating roller 41 is made of a material with good thermal conductivity, corrosion resistance and pressure resistance. If a channel for the flow of the heating medium is directly dug out in the heating roller 41, the material and manufacturing process of the heating roller 41 itself are required to be high, and the cost is high. However, it is relatively easy to dig out a space for accommodating the pipe. Through mechanical processing, casting and other processes, the space for the pipe can be reserved during the molding process of the heating roller 41, and then the pre-made circulation pipe 47 can be installed in these spaces. In this way, the size and position of the pipe can be better controlled to ensure the installation accuracy and stability of the circulation pipe 47. Digging out space to accommodate the pipe can better fix and support the circulation pipe 47. During the rotation of the heating roller 41, the circulation pipe 47 needs to withstand the flow pressure and centrifugal force of the heating medium. If the pipe is directly dug out, it may be easily deformed or damaged due to lack of sufficient support, affecting the flow and heating effect of the heating medium. The reserved space for installing the pipeline can ensure the stability of the circulation pipeline 47 in the heating roller 41 through a reasonable support structure, ensuring the smooth flow and uniform heating of the heating medium. For maintenance and repair, it is also more convenient to dig out space to accommodate the pipeline. If the circulation pipeline 47 is blocked or leaking, it can be more easily taken out of the reserved space for inspection or replacement without having to disassemble and repair the entire heating roller 41 on a large scale.

[0035] In actual use, the heating motor 421 can effectively transmit power to the heating roller 41 through the gear meshing connection to realize the rotation of the heating roller 41. Gear transmission has the advantages of accurate transmission ratio and high efficiency, and can ensure that the heating roller 41 rotates at a stable speed, thereby ensuring the uniformity and controllability of the heating process. Multiple circulation pipes 47 are arranged around the rotation axis of the heating roller 41, so that the heating medium can be more evenly distributed inside the heating roller 41. The circulation pipes 47 at different positions can heat different areas of the heating roller 41, thereby reducing the temperature difference and improving the uniformity of heating. The setting of the heating pump 49 can ensure that the heating medium circulates in the heating roller 41 to maintain a stable heating effect. The heating pump 49 can provide sufficient power to overcome the pipeline resistance, so that the heating medium always flows in the circulation pipe 47 at a certain flow rate. By adjusting the flow rate and pressure of the heating pump 49, the circulation speed of the heating medium can be controlled, thereby achieving precise control of the temperature of the heating roller 41.

[0036] In actual use, by setting a circulation pipeline 47 in the heating roller 41, and using the oil inlet pipeline 45 of the left end shaft head 43 and the oil outlet pipeline 46 of the right end shaft head 44 to form a circulation loop, the heating medium (such as the heating medium) can flow evenly inside the heating roller 41, thereby achieving uniform heating of the heating roller 41, and in conjunction with the heater 48 on the frame 1, the temperature of the heating roller 41 can be more accurately controlled. The multiple circulation pipelines 47 increase the contact area between the heating medium and the inner wall of the heating roller 41, and improve the heat conduction efficiency. The heating medium can transfer heat to the heating roller 41 more quickly, thereby shortening the heating time and improving production efficiency. The internal circulation heating method makes the contact area between the heating medium and the heating roller 41 larger and the heat transfer efficiency higher. Since the heating medium circulates inside the heating roller 41, the temperature of the heating roller 41 can be effectively kept stable and the heat loss can be reduced.

[0037] Specifically, the number of cooling plates 61 is set to be multiple, and the multiple cooling plates 61 are arranged in parallel on both sides of the coated pearl cotton roll material. The number of cooling holes 62 is set to be multiple. A cooling cavity 63 is provided in the cooling plate 61 to communicate with an external refrigerator. The cooling hole 62 is connected to the cooling cavity 63 and the cooling hole 62 is semi-elliptical in the direction from the cooling cavity 63 to the outside of the cooling plate 61, and the long axis direction of the semi-ellipse is consistent with the feeding direction of the roll material.

[0038] In actual use, the multiple cooling holes 62 on the cooling plate 61 are connected to the cooling cavity 63, so that the cooling medium (such as cold air) can be more evenly distributed on the surface of the cooling plate 61, fully contacting with the pearl cotton coil, and further improving the cooling effect. The cooling hole 62 is elliptical in the direction from the cooling cavity 63 to the outside of the cooling plate 61, and the long axis direction of the ellipse is consistent with the feeding direction of the coil. Such a design enables the cooling medium to be directional cooled along the feeding direction of the pearl cotton coil, matching the movement direction of the coil, and improving the pertinence and effectiveness of the cooling. Directional cooling can reduce the generation of cooling dead corners, ensure that all parts of the pearl cotton coil can be fully cooled, and thus improve the stability of the coating quality. The parallel arrangement of multiple cooling plates 61 and the uniform distribution of cooling holes 62 enable the cooling medium to act evenly on both sides of the pearl cotton coil, ensuring the uniformity of cooling. This helps to avoid deformation, warping and other problems of the pearl cotton coil due to uneven local cooling, and improves the quality of the product.

[0039] Specifically, the coating device 5 has a coating driving mechanism 52 for driving the coating roller 51 to rotate, and a coating adjusting mechanism 53 for adjusting the distance between the coating roller 51 and the coil. The number of coating rollers 51 is set to be multiple, and the multiple coating rollers 51 are arranged in parallel on both sides of the pearl cotton coil released by the unwinding roller 21. The surface of the coating roller 51 is provided with a plurality of arranged recessed holes 511.

[0040] In actual use, the coating drive mechanism 52 ensures that the coating roller 51 can rotate stably, providing reliable power for the coating process. The coating adjustment mechanism 53 can accurately adjust the distance between the coating roller 51 and the coil, so as to adapt to the pearl cotton coil and coating materials of different thicknesses. Fine adjustment can be made according to the actual situation to ensure that the pressure and fit of the coating reach the best state and improve the coating quality. The pearl cotton coil is coated from both sides of the coil feeding direction to increase the contact area and uniformity of the coating. The joint action of multiple coating rollers 51 can make the coating more compact and smooth, and reduce the generation of bubbles and wrinkles. Several concave holes 511 arranged on the surface of the coating roller 51 can increase the friction between the coating roller 51 and the coating material, prevent the coating material from sliding during the coating process, and ensure the accuracy and stability of the coating. At the same time, the concave holes 511 can also make the coating material better fit on the surface of the pearl cotton coil and improve the firmness of the coating.

[0041] In this embodiment, the coating drive mechanism 52 has a coating motor 521 arranged on the frame 1, and a first coating gear 522 is provided on the output shaft of the coating motor 521. A second coating gear 523 is rotatably provided on the frame 1. The second coating gear 523 and the coating roller 51 are coaxially arranged, and the first and second coating gears 523 are meshingly connected.

[0042] In actual use, the laminating motor 521 is connected by meshing the first laminating gear 522 on the output shaft with the second laminating gear 523 to transmit power to the laminating roller 51. The gear transmission has the characteristics of high precision and stable transmission ratio, which can ensure that the laminating roller 51 rotates at an accurate speed and torque, thereby achieving accurate laminating operation. Due to the high precision of the gear transmission, the rotation speed and torque of the laminating roller 51 can be accurately controlled. This enables the laminating roller 51 to apply uniform pressure to the film, ensuring that the film and the coated material fit tightly without defects such as bubbles and wrinkles.

[0043] Specifically, the frame 1 is provided with a first accommodating opening 11 for accommodating the coating adjustment mechanism 53, and the accommodating opening is provided with a coating adjustment motor 531 and a first guide rail 535. The output shaft of the coating adjustment motor 531 is provided with a first screw 532, and the other end of the first screw 532 is rotatably set on the first accommodating opening 11.

[0044] In actual use, the use of the coating adjustment motor 531 makes the distance adjustment between the coating roller 51 and the coil more accurate and automatic. By controlling the rotation speed and direction of the coating adjustment motor 531, the position of the coating roller 51 can be finely adjusted to meet the coating requirements of materials of different thicknesses and improve the stability of the coating quality. As a transmission component, the first screw 532 has the characteristics of high transmission accuracy and good stability. It can convert the rotational motion of the coating adjustment motor 531 into linear motion, accurately control the position of the first bearing seat 533, thereby driving the coating roller 51 to move, and ensuring that the distance between the coating roller 51 and the coil is always in the best state. The coating roller 51 is rotatably connected to the first bearing seat 533 through a bearing. This connection method ensures the smoothness and reliability of the rotation of the coating roller 51.

[0045] Specifically, the unwinding device 2 has an unwinding drive mechanism 23 for driving the unwinding roller 21 to rotate, and a film material drive mechanism 24 for driving the film material roller 22 to rotate. Adjustable stop plates 25 are provided at both ends of the unwinding roller 21. The stop plate 25 has a stop portion 251 for resisting and stopping the pearl cotton roll material, and a fixed portion 252 connected to the unwinding roller 21. A plurality of adjustment springs 253 are provided between the stop portion 251 and the fixed portion 252 for adjusting the distance between the stop portion 251 and the pearl cotton roll material. The plurality of adjustment springs 253 are arranged around the rotation axis of the unwinding roller 21.

[0046] In actual use, the stopper 251 can resist and stop the pearl cotton coil material to prevent the coil material from being too loose or offset during the unwinding process. This helps to maintain the stable unwinding of the coil material and ensure the continuity and uniformity of the unwinding. The setting of the adjustment spring 253 enables the stopper 251 to automatically adjust the distance between the pearl cotton coil material and the pearl cotton coil material according to the change in the diameter of the coil material. As the coil material is gradually released and the diameter decreases, the adjustment spring 253 can push the stopper 251 to always maintain appropriate contact with the coil material to ensure the stopping effect. The adjustment spring 253 plays a buffering role between the stopper 251 and the coil material. When the coil material is impacted or vibrated by external force, the adjustment spring 253 can absorb part of the energy and reduce the direct impact force on the coil material, thereby protecting the coil material from damage. If there is no adjustment spring 253, the stopper 251 may directly and hard contact with the coil material, which is easy to cause surface damage or deformation of the coil material. The existence of the adjustment spring 253 makes the contact between the stopper 251 and the coil material softer, reducing the risk of damage to the coil material.

The rotation speed of the winding roller 31 can be accurately controlled according to the requirements of the production speed to ensure the continuity and stability of the winding process. The lifting mechanism 34 enables the winding roller 31 to be automatically lifted and lowered, which is convenient for operators to replace and install the coil. During the winding process, the height of the winding roller 31 can be automatically adjusted according to the thickness of the coil to ensure the neatness and tightness of the winding. The material receiving vehicle 33 is convenient for transferring the coil wound by the winding roller 31, which improves the automation degree and work efficiency of production. A pair of clamping arms 345 on the material receiving vehicle 33 can firmly clamp the coil wound by the winding roller 31 to prevent the coil from loosening or falling during the transfer process. The power assembly 35 provides clamping force for the clamping arm 345 to ensure the stability and reliability of the clamping. The clamping surface of the clamping arm 345 is in an arc shape, which matches the shape of the winding roller 31, can better fit the coil, increase the contact area of ​​the clamping, and improve the stability of the clamping. At the same time, the arc-shaped clamping surface also helps to reduce the local pressure on the coil and prevent the coil from deforming. The protective layer 346 on the two clamping surfaces can effectively protect the coil from being worn and damaged by the clamping surfaces. The protective layer 346 is usually made of soft and wear-resistant materials, such as rubber, plastic, etc., which can play a buffering and protective role during the clamping process to ensure that the surface quality of the coil is not affected.

[0052] In actual use, the tension sensor 71 can sense the tension during the coil feeding process in real time and provide accurate data feedback for tension adjustment. By accurately monitoring the tension changes, abnormal tension can be discovered in time so that adjustments can be made quickly to ensure that the tension of the coil is always kept within a suitable range during the coating process.
