Description

Technical Field

[0001] This invention relates to the field of film shaping technology, specifically to an environmentally friendly, multifunctional decorative film anti-lateral shrinkage shaping system. Background Technology

[0002] Films are widely used in many fields and are an indispensable product in people's production and life. After the film is made into raw film material, heat setting is an important step in the process of eliminating internal stress and stabilizing surface tension and other technical indicators. The purpose is to eliminate internal stress in the film and increase dimensional stability. Lateral shrinkage will occur during film heat setting. Lateral shrinkage can be suppressed by pressing the film edge with rollers or by clamping the film edge with chain clamps.

[0003] When the roller is working, it needs to apply a constant and uniform clamping force to the film to restrain the lateral shrinkage of the film. However, during the continuous operation of the film, the film thickness is uneven, which causes the clamping force of the roller on the film to fluctuate and cannot be kept stable. When the clamping force is insufficient, the roller cannot effectively restrain the film, and thus it is difficult to suppress the lateral shrinkage of the film. Summary of the Invention

[0008] Preferably, the fixing component includes several fixing plates fixedly connected to the inner wall of the molding chamber, two fixing blocks fixedly connected to the outer wall of each fixing plate, and a movable plate slidably connected to the inner wall of each fixing block. Two sliding grooves are opened on the outer wall of the movable plate, and two high-strength spring sheets are fixedly connected to the outer wall of the movable plate. The movable plate extends protruding blocks to both sides, and high-strength spring sheets are fixed on the protruding blocks. The two fixed blocks are set in a mirror image, the two sliding grooves are set in a mirror image, the two high-strength spring sheets are set in a mirror image, and the side of the two high-strength spring sheets away from the movable plate is fixedly connected to the fixed blocks.

[0009] Preferably, the buffer assembly includes a support plate slidably connected to the inner wall of the sliding groove, a spring fixedly connected to the top of the support plate, and a roller rotatably connected to the bottom of the support plate. Among them, the side of spring one away from the support plate is fixedly connected to the moving plate, and the elastic potential energy of the high-strength spring sheet is much stronger than that of spring one.

[0010] Preferably, the limiting assembly includes two connecting rods rotatably connected to the outer wall of the support plate, a limiting block is fixedly connected to the outer wall of the two connecting rods on the side away from the support plate, and a torsion spring is fixedly connected to the side of the two connecting rods away from the limiting block; The two connecting rods are mirror-shaped and can rotate separately. The torsion spring extends out of the support plate from the middle position. The torsion spring is fixedly connected to the connecting rods only on both sides with a small area. The limiting block is provided with an inclined surface. The torsion spring is initially in a compressed state.

[0011] Preferably, the rolling assembly includes two mounting slots formed on the inclined outer wall of the limiting block, two inclined rollers are rotatably connected to the inclined outer wall of the mounting slots, and two springs are fixedly connected to the inner walls of the two mounting slots. The inclined rollers are also rotatably connected to the connecting rod. The two inclined rollers are in close contact with the inclined surface of the connecting rod. The two inclined rollers maintain a certain distance from the inclined surface of the limiting block. The two springs are initially in a free state.

[0012] Preferably, the scraping assembly includes two rotating shafts fixedly connected to the outer wall of the support plate, and scraping plates are fixedly connected to the outer walls of the two rotating shafts; The scraper blade is in close contact with the roller on the side furthest from the rotating shaft.

[0013] Preferably, the adjusting assembly includes two wedge-shaped blocks slidably connected to the inner wall of the fixed block, and adjusting bolts are fixedly connected to the outer walls of the two wedge-shaped blocks; The top center of the movable plate protrudes upwards, and the wedge block is in close contact with the bottom surface of the movable plate. The side of the wedge block that contacts the movable plate has the same inclination as the top of the movable plate.

[0014] The present invention has the following beneficial effects: (1) When the film advances, when the roller passes through the thicker part of the film, the roller is subjected to an upward force, which causes the roller to drive the support plate to move upward. When the roller encounters the thinner part, the roller moves downward, causing the support plate and the moving plate to move downward a certain distance. At this time, the protruding block of the moving plate moves downward synchronously with it. After the roller passes the thinner film, when the roller rolls, the roller can always generate a stable force on the film. Through the application of the above components, the uneven thickness of the film during the continuous operation of the film is effectively prevented, which causes the roller to fluctuate the pressing force on the film and cannot maintain stability. When the pressing force is insufficient, the roller cannot effectively constrain the film, and thus it is difficult to suppress the lateral shrinkage of the film.

[0015] (2) This invention utilizes the characteristic of the rollers moving up and down in the above-mentioned equipment. When the film is heat-set, the rollers press down on the edges to prevent lateral shrinkage. At this time, the area pressed down by the rollers is pulled, causing wrinkles to appear on the film edges. The tilting roller contacts the film and applies a certain pressure to it. Affected by the movement of the film, the tilting roller rotates around the central axis of the spring. Figure 10 As shown, when the tilting roller on the left rotates, it generates a force to the left, which in turn exerts a force on the film to the left, causing the film to unfold to the left. When the tilting roller on the right rotates, it generates a force to the right, which in turn exerts a force on the film to the right, thus unfolding the wrinkles. By using the above components, the problem of wrinkles caused by lateral contraction when the rollers press on the film is effectively prevented. The wrinkles are difficult to pass through the rollers and accumulate in front of the rollers, leading to tearing of the film and tear marks penetrating deep into the center of the film.

[0016] (3) This invention utilizes the feature that the moving plate of the above-mentioned component moves within a small range on the inner wall of the fixed block. By adjusting the adjusting bolt, the distance between the two wedge blocks can be adjusted, thereby driving the two wedge blocks to move towards each other and press the moving plate downward as a whole. At this time, the distance between the support plate and the heating roller decreases, that is, the distance between the roller and the heating roller decreases, and the pressure between the roller and the heating roller increases. Through the application of the above-mentioned component, it effectively prevents the problem of difficulty in adjusting the pressure of the roller on the film when dealing with films of different initial thicknesses, thus preventing the problem of machine adjustment time. Furthermore, by fixing the distance between the two wedge blocks, the pressure applied to the film by multiple rollers is kept basically consistent, alleviating the problem of uneven pressure of multiple rollers caused by independent control of rollers.

[0017] (4) The present invention utilizes the characteristics of the film passing through the rollers in the above-mentioned equipment, such as Figure 8 As shown, a film adheres to the left side of the roller, causing some of the film to rotate clockwise with the roller at a certain angle. This further stretches the wrinkled film on the right side of the roller, and the tear may penetrate into the center of the film. By setting a scraper on the rear side of the roller, the scraper is always in contact with the rear surface of the roller to remove the film adhering to the roller. The application of the above components effectively prevents the film from adhering to the roller surface when passing through the roller, further stretching the film, and causing the tear to penetrate into the center of the film.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1-5 This invention is an environmentally friendly, multifunctional decorative film anti-lateral shrinkage shaping system, comprising a calender 13, a shaping chamber 14 fixedly connected to the left side of the calender 13, a cooling cutter 15 fixedly connected to the left side of the shaping chamber 14, a winding machine 16 fixedly connected to the left side of the cooling cutter 15, and a plurality of heating rollers 17 rotatably connected to the inner wall of the calender 13, and further comprising: Fixing mechanism 1 is slidably disposed on the inner wall of the molding chamber 14; Deploy component 2, which is fixedly installed on the inner wall of the fixing mechanism 1; Auxiliary mechanism 3 is fixedly installed on the outer wall of fixed mechanism 1; The shaping chamber 14 is an insulated structure to prevent the internal temperature from being greatly affected by the external temperature. The cooling cutter 15 is equipped with cooling rollers and a cutting device. After the raw material is added to the extruder and melted, it is drawn into the calender 13 for calendering, and then enters the shaping chamber 14 for heat setting. Then it is drawn into the cooling rollers on the cooling cutter 15 to gradually reduce the film temperature. After the waste edge is removed by the cutting device, it is wound up by the winding machine 16.

[0023] Fixed mechanism 1 includes: Fixing component 11 is fixedly installed on the inner wall of the molding chamber 14; The buffer assembly 12 is slidably disposed on the inner wall of the fixed assembly 11; The waste edges cut off by the cooling cutter 15 are collected, crushed, and added back to the extruder for subsequent production. The plain film rolls wound up by the winding machine 16 are moved to the color printing machine to print decorative colors on the film.

[0024] Expanding component 2 includes: Limiting component 21 is rotatably disposed on the outer wall of fixed component 11; Rolling component 22 is rotatably mounted on the inner wall of limiting component 21; The limiting component 21 restricts the movement direction of the rolling component 22.

[0025] Auxiliary mechanism 3 includes: Scraping component 31 is rotatably disposed on the bottom outer wall of buffer component 12; Adjustment component 32 is slidably disposed on the inner wall of the middle part of fixed component 11; Among them, the scraping component 31 can remove some of the adhered material, and the adjusting component 32 can adjust the height of the buffer component 12; In use, during longitudinal stretching and heat setting, the rollers are usually driven by electric push rods to press the heating roller 17, clamping the two sides of the film on the heating roller 17 to prevent the film from shrinking laterally during setting. After the film is wrapped on the heating roller 17, several electric push rods are fixedly installed in the space on the left side of the setting chamber 14. When the electric push rods are started, the entire fixed plate 111 moves up and down. When the roller 123 contacts the heating roller 17, the electric push rods are turned off, and the fixed plate 111 remains in a fixed position.

[0026] Example 2, please refer to Figures 4-11 This invention is an environmentally friendly multifunctional decorative film anti-lateral shrinkage shaping system. Based on Example 1, the fixing component 11 includes several fixing plates 111 fixedly connected to the inner wall of the shaping chamber 14. Two fixing blocks 112 are fixedly connected to the outer wall of each fixing plate 111. A movable plate 113 is slidably connected to the inner wall of each fixing block 112. Two sliding grooves 114 are opened on the outer wall of the movable plate 113. Two high-strength elastic pieces 115 are fixedly connected to the outer wall of the movable plate 113. Among them, the movable plate 113 extends protruding blocks to both sides, and high-strength spring pieces 115 are fixed on the protruding blocks. The two fixed blocks 112 are set in a mirror image, the two sliding grooves 114 are set in a mirror image, the two high-strength spring pieces 115 are set in a mirror image, and the side of the two high-strength spring pieces 115 away from the movable plate 113 is fixedly connected to the fixed block 112.

[0027] The buffer assembly 12 includes a support plate 121 that is slidably connected to the inner wall of the sliding groove 114. A spring 122 is fixedly connected to the top of the support plate 121, and a roller 123 is rotatably connected to the bottom of the support plate 121. Among them, the side of spring 122 away from the support plate 121 is fixedly connected to the moving plate 113, and the elastic potential energy of the high-strength elastic piece 115 is much stronger than that of spring 122. The support plate 121 is adapted to the sliding groove 114, and the initial state of the support plate 121 is the bottom of the sliding groove 114; As the film advances, the heating roller 17 drives the roller 123 to rotate counterclockwise. At this time, the roller 123, subjected to the friction of the film, rotates clockwise. During rotation, the roller 123 presses against the edge of the film, thus alleviating lateral shrinkage. During the film's movement, the film thickness varies significantly. When the roller 123 passes through a thicker section of the film, it experiences an upward force, causing the support plate 121 to move upward. The support plate 121 then moves upward along the sliding groove 114. At this point, the spring 122 transitions from a free state to a compressed state. When the roller 123 passes the thicker section and enters a thinner section, the spring 122 transitions from a compressed state to a free state, releasing increased elastic potential energy and pushing the support plate 121 and the roller 123 downward, continuing to press against the film. When the roller 123 encounters a thinner section, such as... Figure 8 As shown, the support plate 121 is at the bottom of the sliding groove 114. At this time, the elastic potential energy accumulated by the spring 122 remains basically unchanged. The roller 123 moves down, causing the support plate 121 and the moving plate 113 to move down a certain distance. At this time, the protruding block of the moving plate 113 moves down synchronously with it. After the roller 123 passes over the thinner film, the roller 123, the support plate 121 and the moving plate 113 move down a certain distance under the influence of gravity. When the roller 123 rolls, the roller 123 can always generate a stable force on the film.

[0028] The limiting component 21 includes two connecting rods 211 rotatably connected to the outer wall of the support plate 121. A limiting block 212 is fixedly connected to the outer wall of the two connecting rods 211 on the side away from the support plate 121. A torsion spring 213 is fixedly connected to the side of the two connecting rods 211 away from the limiting block 212. The two connecting rods 211 are mirror images and can rotate separately. The torsion spring 213 extends out of the support plate 121 from the middle position. The torsion spring 213 is fixedly connected to the connecting rods 211 only on both sides. The limiting block 212 is provided with an inclined surface. The torsion spring 213 is initially in a compressed state.

[0029] The rolling assembly 22 includes two mounting slots 221 formed on the inclined outer wall of the limiting block 212. Two inclined rollers 222 are rotatably connected to the inclined outer wall of the mounting slot 221. Springs 223 are fixedly connected to the inner walls of the two mounting slots 221. Among them, the tilting roller 222 is also rotatably connected to the connecting rod 211. The two tilting rollers 222 are in close contact with the tilting surface of the connecting rod 211. The two tilting rollers 222 maintain a certain distance from the tilting surface of the limiting block 212. The two springs 223 are initially in a free state. When the film is heat-set, rollers press down on the edges to prevent lateral shrinkage. At this time, the areas pressed down by the rollers are stretched, causing wrinkles at the film edges. As the wrinkles from one roller move to the next, they pass over the tilting roller 222. The torsion spring 213, with its preset initial torsional force, compresses the connecting rod 211, causing it to rotate downwards. This brings the tilting roller 222 into contact with the film and applies pressure. Influenced by the film's movement, the tilting roller 222 rotates around the central axis of the spring 223. Figure 10 As shown, when the left-side tilting roller 222 rotates, it generates a force to the left, which in turn exerts a force to the left on the film, causing the film to unfold to the left. When the right-side tilting roller 222 rotates, it generates a force to the right, which in turn exerts a force to the right on the film, thus unfolding the wrinkles. The bottom width of the two tilting rollers 222 is greater than the width of roller 123, allowing the film within the width range of roller 123 to pass smoothly. By setting spring 223 and providing a moving gap between the tilting rollers 222 and the inclined surface of the limiting block 212, the two tilting rollers 222 can move in opposite directions. When too much wrinkled film accumulates on the side of the tilting rollers 222 that is far apart from each other, it can compress the two moving in opposite directions a certain distance, causing spring 223 to deform. When the wrinkles on both sides of the tilting rollers 222 decrease, spring 223 releases elastic potential energy, driving the two tilting rollers 222 to move in opposite directions.

[0030] The adjustment assembly 32 includes two rotating shafts 311 fixedly connected to the outer wall of the support plate 121, and a scraper 312 is fixedly connected to the outer wall of the two rotating shafts 311. The scraper 312 is in close contact with the roller 123 on the side away from the rotating shaft 311.

[0031] The scraping assembly 31 includes two wedge-shaped blocks 321 that are slidably connected to the inner wall of the fixed block 112, and adjusting bolts 322 are fixedly connected to the outer walls of the two wedge-shaped blocks 321. The top center of the movable plate 113 protrudes upwards, and the wedge block 321 is in close contact with the bottom surface of the movable plate 113. The side of the wedge block 321 that contacts the movable plate 113 has the same inclination as the top of the movable plate 113.

[0032] One specific application of this embodiment is as follows: After the raw material is added to the extruder and melted, it is drawn into the calender 13 for calendering, and then enters the setting chamber 14 for heat setting. After that, it is drawn into the cooling roller on the cooling cutter 15 to gradually reduce the film temperature. After the waste edge is removed by the cutting device, it is wound up by the winding machine 16. The waste edge removed by the cooling cutter 15 is collected, crushed and added back to the extruder for subsequent production. The plain film roll wound up by the winding machine 16 is moved to the color printing machine to print decorative colors on the film.

[0033] In use, during longitudinal stretching and heat setting, the rollers are typically driven by electric push rods to press the heating roller 17, clamping the film on both sides of the heating roller 17 to prevent lateral shrinkage of the film during setting. After the film is wrapped onto the heating roller 17, several electric push rods are fixedly installed in the space on the left side of the setting chamber 14. Activating the electric push rods moves the entire fixed plate 111 up and down. When the rollers 123 contact the heating roller 17, the electric push rods are deactivated, and the fixed plate 111 remains in its fixed position. Figure 6 As shown, when the film advances, the heating roller 17 drives the roller 123 to rotate counterclockwise. At this time, the roller 123 is subjected to the friction of the film and rotates clockwise. During rotation, the roller 123 presses against the edge of the film, thereby alleviating lateral shrinkage. During the film's movement, the film thickness varies significantly. When the roller 123 passes through a thicker section of the film, it experiences an upward force, causing the support plate 121 to move upward. The support plate 121 then moves upward along the sliding groove 114. At this time, the spring 122 changes from a free state to a compressed state. When the roller 123 passes the thicker section and enters the thinner section, the spring 122 changes from a compressed state to a free state, releasing increased elastic potential energy and pushing the support plate 121 and the roller 123 downward, continuing to press against the film. When the roller 123 encounters a thinner section, as... Figure 8As shown, the support plate 121 is at the bottom of the sliding groove 114. At this time, the elastic potential energy accumulated by the spring 122 remains basically unchanged. The roller 123 moves down, causing the support plate 121 and the moving plate 113 to move down a certain distance. At this time, the protruding block of the moving plate 113 moves down synchronously with it. After the roller 123 passes over the thinner film, the roller 123, the support plate 121, and the moving plate 113 move down a certain distance under the influence of gravity. When the roller 123 rolls, the roller 123 can always generate a stable force on the film. Through the application of the above components, the uneven thickness of the film during continuous operation is effectively prevented, which causes the roller's pressing force on the film to fluctuate and cannot remain stable. When the pressing force is insufficient, the roller cannot effectively constrain the film, thus making it difficult to suppress the lateral shrinkage of the film.

[0034] Utilizing the up-and-down movement of rollers 123 in the aforementioned device, during film heat setting, the rollers press down on the edges to prevent lateral shrinkage. At this time, the areas pressed down by the rollers are pulled, causing wrinkles to appear at the film edges. When the wrinkles created by one roller move to the next roller, they pass over the tilting roller 222. The torsion spring 213, with its preset initial torsional force, compresses the connecting rod 211, causing it to rotate downwards. This causes the tilting roller 222 to contact the film and apply pressure. Influenced by the film's movement, the tilting roller 222 rotates around the central axis of the spring 223. Figure 10 As shown, when the left-side tilting roller 222 rotates, it generates a force to the left, which in turn exerts a force to the left on the film, causing it to unfold to the left. When the right-side tilting roller 222 rotates, it generates a force to the right, which in turn exerts a force to the right on the film, thus unfolding the wrinkles. Furthermore, the bottom width of both tilting rollers 222 is greater than the width of roller 123, allowing the film to pass smoothly within the width range of roller 123. By setting spring 223 and providing a movement gap between the tilting rollers 222 and the inclined surface of the limiting block 212, the two tilting rollers... The rollers 222 can move in opposite directions. When too many wrinkled films accumulate on the side of the inclined rollers 222 that are far apart from each other, they can compress the two rollers that move in opposite directions a certain distance, causing the spring 223 to deform. When the wrinkles on both sides of the inclined rollers 222 decrease, the spring 223 releases its elastic potential energy, causing the two inclined rollers 222 to move in opposite directions. Through the application of the above components, the problem of wrinkles caused by lateral contraction when the rollers 123 compress the film is effectively prevented. The wrinkles are difficult to pass through the rollers 123 and accumulate in front of the rollers 123, resulting in tearing of the film and tear marks penetrating into the center of the film.

[0035] Utilizing the characteristic of the aforementioned component, the moving plate 113 moves within a small range on the inner wall of the fixed block 112. By adjusting the adjusting bolt 322, the distance between the two wedge blocks 321 can be adjusted, thereby causing the two wedge blocks 321 to move towards each other. Since the wedge blocks 321 and the top surface of the moving plate 113 are inclined, the moving plate 113 is forced to move downward as a whole, thereby forcing the two high-strength spring sheets 115 to change from a free state to a compressed state. As a result, the high-strength spring sheets 115 exert an upward force on the moving plate 113. Because the top of the moving plate 113 is restricted by the wedge blocks 321, the moving plate 113... 3. Keeping the position unchanged, the distance between the support plate 121 and the heating roller 17 decreases, that is, the distance between the roller 123 and the heating roller 17 decreases, and the pressure between the roller 123 and the heating roller 17 increases. Through the application of the above components, the problem of difficulty in adjusting the pressure of the roller 123 on the film when dealing with films of different initial thicknesses is effectively prevented, thus avoiding the problem of machine adjustment time. Furthermore, by fixing the distance between the two wedge blocks 321, the pressure applied to the film by multiple rollers 123 is kept basically consistent, alleviating the problem of uneven pressure of multiple rollers 123 caused by independently controlling the rollers 123.

[0036] Utilizing the characteristics of the film passing through roller 123 in the aforementioned equipment, when the film passes through roller 123, due to the heating of the film, a portion of the plasticizer will be released. Since the outer wall of the heating roller 17 is made of a non-adhesive material, but to prevent the roller 123 from making hard contact with the heating roller 17 and cutting the film, roller 123 is made of a high-temperature resistant non-metallic material. At this time, the film will adhere to the surface of roller 123, such as... Figure 8 As shown, a film adheres to the left side of roller 123, causing part of the film to rotate clockwise with roller 123 at a certain angle. This further stretches the wrinkled film on the right side of roller 123, and the tear may penetrate into the center of the film. By setting a scraper 312 on the rear side of roller 123, the scraper 312 is always in contact with the rear wheel surface of roller 123 to remove the film adhering to roller 123. Through the application of the above components, the problem of the film adhering to the surface of roller 123 and further stretching the film, causing the tear to penetrate into the center of the film, is effectively prevented.
