Description

Technical Field

[0001] This utility model belongs to the field of casting machine technology, specifically relating to a winding structure for a stone paper casting machine. Background Technology

[0002] Stone paper is an environmentally friendly new material made primarily of calcium carbonate powder and using polymer resin as a binder. It is produced through a process of mixing, casting, and stretching. The production process typically employs a "casting + biaxial stretching" technique: molten material is extruded through a T-die and forms a 0.08–0.3 mm thick initial sheet on a casting roller. Subsequently, it undergoes longitudinal and transverse stretching, surface coating, and corona treatment, and is finally wound into a master roll by a winding unit.

[0003] In the actual winding process of stone paper, the coupling relationship between "roll diameter-tension-contact pressure" is extremely sensitive. Under the same formula, for every 100mm increase in roll diameter, the contact pressure increases by about 0.8N / mm. If the winding height is not adjustable, it will result in insufficient wrap angle between the small roll diameter film surface and the guide roller, resulting in "floating sheet" phenomenon, causing slippage and bottom wrinkles. The height difference between the large roll diameter paper core and the center of the downstream traction roller becomes larger, that is, the incident angle of the film entering the winding area is too large, and creases appear on the edge. Utility Model Content

[0004] The purpose of this invention is to provide a winding structure for a stone paper casting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a winding structure for a stone paper casting machine, comprising symmetrically arranged guide rails, a base plate slidably disposed between the guide rails, a top plate disposed above the base plate, a winding groove disposed on the top of the top plate, a first slide rail symmetrically disposed on the right side of the top of the base plate, a first slide roller slidably connected between the first slide rails, a second slide rail symmetrically disposed on the right side of the bottom of the top plate, a second slide roller slidably connected between the second slide rails, a first fixed seat disposed on the left side of the top of the base plate, a second fixed seat disposed on the left side of the bottom of the top plate, a first swing arm rotatably connected between the first fixed seat and the second slide roller, a second swing arm rotatably connected between the first slide roller and the second fixed seat, and the first swing arm and the second swing arm rotatably connected at the middle by a hinge rod.

[0011] Preferably, the take-up groove is a large-angle V-shape.

[0012] Preferably, an automatic tube threading device is provided on the left side of the guide rail, and an air shaft is slidably provided inside the automatic tube threading device.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this utility model uses a servo motor to drive an "X-type" linkage mechanism to achieve precise vertical lifting of the top plate and the winding groove, effectively adapting to the winding requirements of different roll diameters and avoiding the problem of contact pressure changes caused by changes in roll diameter.

[0014] The winding groove in this utility model adopts a large-angle V-shaped structure, which can automatically guide the film to align with the center, significantly reducing the offset of the film during lifting and introduction, and improving the neatness of winding and the quality of finished products.

[0015] In this utility model, the substrate is connected to the guide rail via a pulley assembly.

[0025] Example 1

[0026] like Figures 1 to 6The winding structure shown is for a stone paper casting machine, including symmetrically arranged guide rails 1, a base plate 2 slidably disposed between the guide rails 1, a top plate 3 positioned above the base plate 2, a winding groove 4 at the top of the top plate 3, first slide rails 5 symmetrically arranged on the top right side of the base plate 2, a first slide roller 6 slidably connected between the first slide rails 5, second slide rails 7 symmetrically arranged on the bottom right side of the top plate 3, a second slide roller 8 slidably connected between the second slide rails 7, a first fixed seat 9 at the top left side of the base plate 2, a second fixed seat 10 at the bottom left side of the top plate 3, a first swing rod 11 rotatably connected between the first fixed seat 9 and the second slide roller 8, a second swing rod 12 rotatably connected between the first slide roller 6 and the second fixed seat 10, and the first swing rod 11 and the second swing rod 12 rotatably connected at their middle portions by a hinge rod 13; a first fixed seat 9 is rotatably connected to... A servo motor 14 is provided, and its output end rotates with the top plate 3. The base plate 2 is slidably disposed between the guide rails 1 via a pulley 152 assembly 15. The pulley 152 assembly 15 includes: mounting plates 151 at the four corners of the bottom of the base plate 2, each mounting plate 151 having a pulley 152 rotatably disposed therein, and a roller 153 connecting the two pulleys 152 on the front side; guide grooves 154 are provided on both the left and right sides of the guide rails 1, and rollers 155 are provided on both the left and right sides of the inner wall of the mounting plate 151, with the rollers 155 in the mounting plate 151 located in the guide grooves 154 respectively; a motor 156 is provided on the front side of the base plate 2, and a sprocket assembly 157 is connected between the roller 153 and the output shaft of the motor 156; the winding groove 4 is a large-angle V-shape; an automatic tube threading device 16 is provided on the left side of the guide rails 1, and an air shaft 161 is slidably disposed within the automatic tube threading device 16.

[0027] This invention uses a servo motor 14 to drive an "X-shaped" linkage mechanism, enabling precise vertical lifting and lowering of the top plate 3 and the winding groove 4. This effectively adapts to the winding requirements of different roll diameters and avoids contact pressure changes caused by variations in roll diameter. The winding groove 4 in this invention adopts a large-angle V-shaped structure, which can automatically guide the film to align with the center, significantly reducing film offset during lifting and introduction, and improving winding neatness and finished product quality. In this invention, the base plate 2 cooperates with the guide rail 1 through the pulley 152 assembly 15. The pulley 152 assembly 15 is equipped with a roller 155 that cooperates with the guide groove 154 to form a sliding pair, driving the base plate 2 to move precisely back and forth under the drive of the motor 156, thereby adjusting the overall position of the entire winding structure to adapt to different process requirements. This invention is equipped with an automatic tube threading device 16 and an air shaft 161 to realize automatic pushing, centering, and locking of the paper core tube. After winding is completed, the full roll can be automatically ejected and a new tube can be replaced, meeting the needs of continuous production and reducing manual intervention.

[0028] Example 2

[0029] like Figures 1 to 5The diagram illustrates a winding structure for a stone paper casting machine, comprising symmetrical guide rails 1 fixedly mounted on the ground or on a production line. A base plate 2 is slidably mounted between the guide rails 1, allowing the base plate 2 to move back and forth along the guide rails 1, thereby adjusting the components mounted above it. A top plate 3 is positioned above the base plate 2, capable of precise up-and-down movement under the influence of a driving force (such as a cylinder, servo motor 14, or other driving structure) to accommodate different roll diameters and process requirements. A winding groove 4, with a large-angle V-shape, is designed at the top of the top plate 3. This groove effectively guides the film to automatically align towards the center, significantly reducing film offset during lifting and introduction, improving the positioning accuracy of the film entering the winding device, and ensuring neat winding and finished product quality.

[0030] Furthermore, such as Figure 6 As shown, an automatic tube threading device 16 is located on the left side of the guide rail 1. An air shaft 161 is slidably installed inside the automatic tube threading device 16 for fixing and driving the paper core tube. Specifically, before winding begins, the automatic tube threading device 16 automatically pushes the paper core tube into the air shaft 161. The mechanical centering mechanism and pneumatic locking unit ensure that the paper core tube and the air shaft 161 are completely aligned and firmly locked, preparing for subsequent high-quality winding operations. After winding is completed, the automatic tube threading device 16 will initiate a roll changing operation, that is, automatically push the paper core tube that is fully wound with film material out of the air shaft 161, and then quickly push a new empty paper core tube into the air shaft 161 and lock it in place. This ensures the needs of continuous stone paper production.

[0031] Example 3

[0032] like Figures 1 to 5 The diagram shows a winding structure for a stone paper casting machine, in which a base plate 2 is slidably disposed between guide rails 1, meaning the base plate 2 can move back and forth along the guide rails 1; furthermore, the base plate 2 is slidably disposed between the guide rails 1 via a pulley 152 assembly 15, meaning the base plate 2 can be precisely controlled electrically, and the pulley 152 assembly 15 specifically includes:

[0033] Mounting plates 151 are provided at the four corners of the bottom of the substrate 2. Each mounting plate 151 is equipped with a pulley 152 that rotates within it. The pulleys 152 are directly supported on the top surface of the guide rail 1. A roller 153 is connected between the two pulleys 152 located on the front side of the substrate 2 to maintain the synchronization of movement on both sides. To further enhance the stability and guiding accuracy of movement, long strip-shaped guide grooves 154 are provided on the left and right sides of the guide rail 1. At the same time, a roller 155 is installed on the left and right sides of the inner wall of the mounting plate 151. The rollers 155 are respectively embedded in the guide grooves 154 on both sides to form a sliding pair, which can effectively resist the lateral force and torque during the movement and prevent the substrate 2 from shaking or getting stuck.

[0034] A motor 156 is provided on the front side of the substrate 2. A sprocket assembly 157 is connected between the roller shaft 153 and the output shaft of the motor 156. After the motor 156 is started, the roller shaft 153 is driven to rotate through the sprocket drive, which in turn drives the pulleys 152 fixed at both ends of the roller shaft 153 to rotate. Under the frictional force generated by the gravity of the substrate 2 and the above components, the rotating pulleys 152 can roll smoothly along the top surface of the guide rail 1, thereby accurately driving the entire substrate 2 to move back and forth. At the same time, the guide roller 155 on the mounting plate 151 also rolls in the guide groove 154, ensuring that the movement of the substrate 2 is smooth, straight and controllable.

[0035] Example 4

[0036] like Figures 1 to 5 The diagram shows a winding structure for a stone paper casting machine. A top plate 3 is provided above the substrate 2. The top plate 3 can move precisely up and down under the drive of a driving force (such as a cylinder, servo motor 14 or other driving structure) to adapt to different roll diameters and process requirements. Specifically, two parallel first slide rails 5 are symmetrically installed on the right side of the top of the substrate 2. A first slide roller 6 that can move laterally along the first slide rails 5 is slidably installed between the first slide rails 5. Correspondingly, two parallel second slide rails 7 are also symmetrically arranged on the right side of the bottom of the top plate 3. A second slide roller 8 is slidably connected between the second slide rails 7.

[0037] A first fixed seat 9 is fixedly installed on the left side of the top of the substrate 2, and a second fixed seat 10 is fixedly installed on the left side of the bottom of the top plate 3. The two ends of the first swing rod 11 are rotatably connected to the first fixed seat 9 and the second sliding roller 8, respectively. The two ends of the second swing rod 12 are rotatably connected to the first sliding roller 6 and the second fixed seat 10, respectively. The middle parts of the first swing rod 11 and the second swing rod 12 are rotatably connected to each other through a hinge rod 13, thereby forming a deformable "X-shaped" linkage mechanism between the substrate 2 and the top plate 3.

[0038] A servo motor 14 is rotatably connected to the first fixed base 9, and the output end of the servo motor 14 is rotatably connected to the top plate 3. The servo motor 14 can be used to adjust the vertical movement of the top plate 3. In practical applications, the output shaft of the servo motor 14 will drive the first sliding roller 6 to slide along the first slide rail 5. At the same time, through the pushing and pulling action of the first swing rod 11 and the second swing rod 12, the top plate 3 and the winding groove 4 on it will perform precise vertical lifting and lowering, thereby realizing the vertical movement adjustment of the top plate 3.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
