Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Such as Figures 1 to 5As shown in the figure, a calendering and coiling device for plastic film according to an embodiment of the present invention includes a first coiling rack 1; one end of the first coiling rack 1 is fixedly connected with a first insertion rod 11; the outer part of the first insertion rod 11 is slidably connected with a second coiling rack 12, and the first insertion rod 11 is inserted into one end of the second coiling rack 12; a plurality of first limiting blocks 13 are slidably connected inside both the first coiling rack 1 and the second coiling rack 12, and the ends of the plurality of first limiting blocks 13 close to each other are arc-shaped; a plurality of first coiling rollers 14 are slidably connected to the first coiling rack 1; a second coiling roller 15 is slidably connected to the second coiling rack 12; clamping mechanisms are respectively arranged on the first coiling rack 1 and the second coiling rack 12, and the clamping mechanisms are used to respectively fix the plurality of first coiling rollers 14 and the second coiling roller 15 on the first coiling rack 1 and the second coiling rack 12; when simultaneously calendering and coiling plastic films of multiple widths, the calender is divided into a material pressing part and a coiling part. First, let the material pressing part extrude and form the plastic film, and then the formed plastic film is coiled by the coiling part. When coiling the plastic film, the first coiling rack 1 and the second coiling rack 12 are inserted and connected to each other and supported through the first insertion rod 11, the other ends of the first coiling rack 1 and the second coiling rack 12 are limited, the plurality of first coiling rollers 14 are slidably placed on the first coiling rack 1, the second coiling roller 15 is slidably placed on the second coiling rack 12, and the plurality of first coiling rollers 14 and the second coiling roller 15 are respectively clamped and fixed by the clamping mechanism cooperating with the extrusion of the arc-shaped ends of the plurality of first limiting blocks 13. The first coiling rollers 14 and the second coiling roller 15 can adjust their installation positions according to the width of the produced plastic film. Subsequently, the first coiling rack 1 and the second coiling rack 12 are driven to rotate synchronously by an external power component, and the plurality of first coiling rollers 14 and the second coiling roller 15 rotate accordingly to coil the plastic films of multiple widths, playing a role in simultaneously calendering and coiling plastic films of multiple widths.

[0024] The clamping mechanism includes a first support base 2, a rotating frame 21, an extrusion insertion block 22, a first elastic member 23, a second support base 24, and a plugging component; the two first support bases 2 are respectively arranged on the sides of the first winding frame 1 and the second winding frame 12 away from each other; the rotating frame 21 is rotatably connected to the first support base 2, and the rotating frame 21 is composed of a rotating rod and a square plate, and the rotating rod is rotatably connected to the first support base 2; the extrusion insertion block 22 is fixedly connected to one side of the square plate of the rotating frame 21, and the end of the extrusion insertion block 22 away from the rotating frame 21 is arranged in an arc shape; the first elastic member 23 is installed on the first limiting block 13; the second support base 24 is sleeved at the clamping joint of the first winding frame 1 and the second winding frame 12; the plugging component is arranged on the rotating frame 21 and is used for the limit connection of the rotating frame 21; when clamping and limiting a plurality of first winding rollers 14 and second winding rollers 15, the second support base 24 is first sleeved at the connection of the first winding frame 1 and the second winding frame 12, the two first support bases 2 are respectively installed at the rotating rods of the two rotating frames 21 for support, the bottom of the first support base 2 is externally connected to an electric displacement component, the two electric displacement components respectively drive the two first support bases 2 to slide relatively, the extrusion insertion blocks 22 on the square plates of the two rotating frames 21 are correspondingly inserted into the interiors of the first winding frame 1 and the second winding frame 12, and the arc-shaped ends of the plurality of first limiting blocks 13 are extruded by the arc-shaped ends of the extrusion insertion blocks 22, so that the plurality of first limiting blocks 13 are respectively extruded and inserted into the interiors of the plurality of first winding rollers 14 and second winding rollers 15. At this time, the plurality of first elastic members 23 are extruded and contracted under force, and after the two plugging components plug and fix the two rotating frames 21 to the first winding frame 1 and the second winding frame 12 respectively, the power component drives the circular rods of the rotating frames 21 connected to the first winding frame 1 and the second winding frame 12 to rotate, realizing the function of clamping the plurality of first winding rollers 14 and second winding rollers 15 and winding a plurality of width plastic films.

[0025] Such as Figures 1 to 4As shown, the plug-in component includes a fixing plate 3, a second plugging rod 31, and a second elastic member 32; a plurality of the fixing plates 3 are fixedly connected to the rotating frame 21; the second plugging rod 31 is slidably connected to the inner wall of the fixing plate 3; the second elastic member 32 is installed between the second plugging rod 31 and the fixing plate 3; a plurality of plugging slots 33 are formed on both the first winding frame 1 and the second winding frame 12, and the plugging slots 33 are arranged corresponding to the second plugging rod 31; when the two rotating frames 21 are respectively connected to the first winding frame 1 and the second winding frame 12, taking the connection between the rotating frame 21 and the first winding frame 1 as an example, the rotating frame 21 drives the extrusion plug 22 to be inserted into the interior of the first winding frame 1 first, and a plurality of fixing plates 3 slide close to one end of the first winding frame 1 along with the rotating frame 21. At this time, a plurality of second plugging rods 31 are pulled to slide on the fixing plate 3, and a plurality of second elastic members 32 are stretched and stressed. When the plurality of second plugging rods 31 are corresponding to the plurality of plugging slots 33 on the first winding frame 1, they are released, and the plurality of second plugging rods 31 are respectively inserted into the plurality of plugging slots 33 to achieve clamping. The connection between the other rotating frame 21 and the second winding frame 12 is the same, which plays a role in clamping the two rotating frames 21 to the first winding frame 1 and the second winding frame 12 respectively.

[0026] As Figures 1 to 5 shown, an arc groove is formed on the inner wall of the first winding roller 14; a plurality of arc blocks 4 are slidably connected to the inner walls of both the first winding frame 1 and the second winding frame 12, and the arc blocks 4 are arranged corresponding to the arc groove; a first spring 41 is fixedly connected to the bottom of the plurality of arc blocks 4; when assembling the plurality of first winding rollers 14 and the second winding rollers 15, due to the deviation of the installation positions of the plurality of first winding rollers 14 and the second winding rollers 15 before clamping, it is difficult to clamp the plurality of first winding rollers 14 and the second winding rollers 15. By using the plurality of arc blocks 4 to be respectively slidably connected to the first winding frame 1 and the second winding frame 12, and the first spring 41 supports at the bottom of the arc blocks 4, during the assembly process of the first winding roller 14, the plurality of arc blocks 4 can be squeezed first. The plurality of arc blocks 4 squeeze the first spring 41 to contract and be stressed until the first winding roller 14 slides to the installation position. The first spring 41 elastically resets and squeezes the arc blocks 4 to be clamped into the arc groove, which can pre-limit the installation position of the first winding roller 14. The same operation is performed for the pre-limitation of the second winding roller 15. After pre-limiting the plurality of first winding rollers 14 and the second winding rollers 15, the plurality of first limiting blocks 13 can be squeezed to clamp and fix the plurality of first winding rollers 14 and the second winding rollers 15, reducing the situation of position deviation when the plurality of first winding rollers 14 and the second winding rollers 15 are clamped, and playing a role in pre-limiting the plurality of first winding rollers 14 and the second winding rollers 15.

[0027] On both sides of multiple first winding rollers 14 and second winding rollers 15, guard plates 51 are sleeved; multiple first magnetic strips 5 are fixedly connected to the multiple guard plates 51; second magnetic strips are fixedly connected to the first winding rollers 14 and second winding rollers 15 near the first magnetic strips 5, the second magnetic strips are arranged corresponding to the first magnetic strips 5, and the second magnetic strips and the first magnetic strips 5 can be magnetically attracted; when calendering and winding plastic films of multiple widths, by the magnetic attraction between the first magnetic strips 5 and the second magnetic strips, the multiple guard plates 51 are respectively fixed on both sides of the multiple first winding rollers 14 and second winding rollers 15, and the multiple guard plates 51 can block both sides of the multiple first winding rollers 14 and second winding rollers 15, so that the wound plastic film can be limited between the two guard plates 51, reducing the serious deviation of the plastic film during winding.

[0028] A third plugging rod 6 is slidably connected to the inner wall of the first winding roller 14 near the first limiting block 13; both sides of the third plugging rod 6 are fixedly connected with third elastic members 61, and the third elastic members 61 are located inside the first winding roller 14; when the two guard plates 51 are sleeved on both sides of the first winding roller 14 and magnetically fixed, by the extrusion of the inserting block 22, the multiple first limiting blocks 13 are extruded into the inside of the first winding roller 14, and the multiple first limiting blocks 13 limit the first winding roller 14. While the first limiting blocks 13 slide, the third plugging rod 6 is immediately extruded to slide and snap into the inside of the guard plate 51, and the two third elastic members 61 on both sides of the third plugging rod 6 are extruded and contracted to be stressed, realizing the function of clamping and limiting the guard plate 51, reducing the occurrence of the two guard plates 51 being thrown off during the winding of the plastic film.

[0029] Multiple pull plates 7 are fixedly connected to the square plate of the rotating frame 21, and the ends of the pull plates 7 far from the square plate are convexly arranged; multiple matching holes 72 are formed in the first winding roller 14, and the matching holes 72 correspond to the pull plates 7; after the plastic film is calendered and wound, the winding of the plastic film is stopped, the clamping connection between the rotating frame 21 and the first winding frame 1 is released, and the rotating frame 21 on the first support seat 2 is driven by the electric displacement component to slide away from the first winding frame 1, and the extrusion block 22 is pulled out of the inside of the first winding frame 1, releasing the limitation of the multiple first limiting blocks 13 on the multiple first winding rollers 14. The multiple pull plates 7 slide along with the rotating frame 21, and the convex parts on the pull plates 7 are used to pull and drag the multiple first winding rollers 14 on the first winding frame 1 to slide, automatically unloading the multiple first winding rollers 14 after winding the plastic film from the first winding frame 1. Subsequently, the multiple first winding rollers 14 located on the multiple pull plates 7 are rotated, and the inner walls of the multiple first winding rollers 14 extrude the multiple friction pads 71 to deform until the convex parts on the multiple pull plates 7 correspond to the multiple matching holes 72, and the first winding rollers 14 after winding the plastic film can be taken off from the multiple pull plates 7. The second winding roller 15 is unloaded in the same way, playing a role in unloading the first winding roller 14 and the second winding roller 15 after winding the plastic film.

[0030] AsFigure 1 , Figure 2 and Figure 6 As shown in Figure 1 , Figure 2 and Figure 6 , a plurality of first clamping blocks 8 are provided on one side of the first winding rack 1 and the second winding rack 12; a sliding rod 81 is slidably connected to the inner walls of the plurality of first clamping blocks 8; one end of the sliding rod 81 away from the first clamping block 8 is fixedly connected to a fixing block 82; a fourth elastic member 83 is sleeved on the sliding rod 81, and the fourth elastic member 83 is located between the first clamping block 8 and the fixing block 82; the top end of the fixing block 82 is slidably connected to a second clamping block 84 through a second spring; an extrusion plate 85 is clamped to the fixing block 82 through the second clamping block 84; a pushing assembly is provided on the outer wall of the second support base 24, and the pushing assembly is used to push the plurality of first clamping blocks 8 installed; when winding the plastic film, if the plastic film is cut off by a cutter, it is easy to cause the plastic film roll to become loose. The plurality of first clamping blocks 8 are clamped and fixed on the pushing assembly, and the extrusion plate 85 is clamped to the fixing block 82 through the second clamping block 84 and the second spring. The extrusion plate 85 fits between the two fence plates 51. As the plastic film continues to be wound, the plastic film roll becomes thicker and thicker on the first winding roller 14. The plastic film roll presses the extrusion plate 85, and the extrusion plate 85 continuously presses the sliding rod 81 to slide. The fourth elastic member 83 is squeezed and contracted under force, and the extrusion plate 85 closely fits on the plastic film roll. After the plastic film is cut off by the cutter, the extrusion plate 85 can tightly press the cut plastic film on the plastic film roll, reducing the loosening of the plastic film roll; at the same time, a triggering assembly can be installed at the extrusion plate 85. When the plastic film roll reaches the set winding thickness, the triggering assembly on the extrusion plate 85 is squeezed and triggered to stop the continuous winding of the plastic film, warning the personnel to check and collect the plastic film roll, playing a role in reminding the material collection.

[0031] The pushing assembly includes a sliding seat 9, an electric push rod 91 and a fixing frame 92; the sliding seat 9 is fixedly connected to one side of the second support base 24; the electric push rod 91 is fixedly connected to the sliding seat 9; the fixing frame 92 is fixedly connected to the output end of the electric push rod 91, and the fixing frame 92 is slidably connected to the sliding seat 9; a plurality of clamping grooves 93 are formed on one side of the fixing frame 92 close to the second support base 24, and the first clamping block 8 can be clamped in the clamping grooves 93; when winding the plastic film, since the winding amount of the plastic film required by each customer is different, the sliding seat 9 is fixed on the second support base 24 to support the electric push rod 91. The output end of the electric push rod 91 drives the fixing frame 92 to slide, and the position of the fixing frame 92 is adjusted according to the thickness of the plastic film winding. The plurality of first clamping blocks 8 are clamped in the plurality of clamping grooves 93, and cooperate with the plurality of extrusion plates 85 to squeeze the plastic film roll. The position of the fixing frame 92 after sliding can adjust the squeezing force of the plurality of extrusion plates 85 on the plastic film roll, so that the squeezing force of the plurality of extrusion plates 85 on the plastic film roll can be adjusted according to the different winding amounts of the plastic film.

[0032] The length of the pressing plate 85 on the side of the first winding roller 14 corresponds to the width between the two baffles 51 on the first winding roller 14; the length of the pressing plate 85 on the side of the second winding roller 15 corresponds to the width between the two baffles 51 on the second winding roller 15, and the pressing plate 85 on the side of the second winding roller 15 is connected by two fixing blocks 82; when winding the plastic film, the width between the two baffles 51 on the first winding roller 14 is suitable for the short pressing plate 85 to fit and press, the width between the two baffles 51 on the second winding roller 15 is suitable for the long pressing plate 85 to fit and press, and the long pressing plate 85 is supported by two or more fixing blocks 82. According to the different widths of the plastic film wound by multiple first winding rollers 14 and second winding rollers 15, the appropriate pressing plate 85 is adaptively installed for pressing, improving the anti-loosening effect of the pressing plate 85 on the plastic film roll.

[0033] Working process: When simultaneously calendering and winding plastic films of multiple widths, the calender is divided into a material pressing part and a winding part. First, let the material pressing part extrude and form the plastic film, and then the formed plastic film is wound by the winding part. When winding the plastic film, the first winding frame 1 and the second winding frame 12 are connected and supported by inserting and connecting the first inserting rod 11. The other ends of the first winding frame 1 and the second winding frame 12 are limited. A plurality of first winding rollers 14 are slidably placed on the first winding frame 1, and the second winding rollers 15 are slidably placed on the second winding frame 12. The arc ends of a plurality of first limiting blocks 13 are clamped and fixed by the clamping mechanism to cooperate with the extrusion of the plurality of first winding rollers 14 and the second winding rollers 15 respectively. The first winding rollers 14 and the second winding rollers 15 can adjust their installation positions according to the width of the produced plastic film. Subsequently, the external power assembly drives the first winding frame 1 and the second winding frame 12 to rotate synchronously, and the plurality of first winding rollers 14 and the second winding rollers 15 rotate accordingly to wind the plastic films of multiple widths, playing the role of simultaneously calendering and winding the plastic films of multiple widths; when clamping and limiting the plurality of first winding rollers 14 and the second winding rollers 15, the second support base 24 is first sleeved at the connection of the first winding frame 1 and the second winding frame 12. Two first support bases 2 are respectively installed at the rotating rods of the two rotating frames 21 for support. The bottom of the first support base 2 is externally connected with an electric displacement assembly. The two electric displacement assemblies drive the two first support bases 2 to slide relatively respectively. The extrusion inserts 22 on the square plates of the two rotating frames 21 are correspondingly inserted into the interiors of the first winding frame 1 and the second winding frame 12. The arc ends of the extrusion inserts 22 squeeze the arc ends of the plurality of first limiting blocks 13, and the plurality of first limiting blocks 13 are respectively squeezed and inserted into the interiors of the plurality of first winding rollers 14 and the second winding rollers 15. At this time, the plurality of first elastic members 23 are squeezed and contracted under force. After the two plugging assemblies plug and fix the two rotating frames 21 to the first winding frame 1 and the second winding frame 12 respectively, the power assembly drives the round rods of the rotating frames 21 connected to the first winding frame 1 and the second winding frame 12 to rotate, realizing the function of clamping and winding the plastic films of multiple widths by the plurality of first winding rollers 14 and the second winding rollers 15; when the two rotating frames 21 are respectively connected to the first winding frame 1 and the second winding frame 12, taking the connection of the rotating frame 21 and the first winding frame 1 as an example for description, the rotating frame 21 drives the extrusion insert 22 to be first inserted into the interior of the first winding frame 1. A plurality of fixing plates 3 slide close to one end of the first winding frame 1 along with the rotating frame 21. At this time, a plurality of second inserting rods 31 are pulled to slide on the fixing plates 3, and a plurality of second elastic members 32 are stretched and stressed. When the plurality of second inserting rods 31 correspond to the plurality of plugging slots 33 on the first winding frame 1, they are released, and the plurality of second inserting rods 31 are respectively inserted into the plurality of plugging slots 33 to achieve clamping. The connection of the other rotating frame 21 and the second winding frame 12 is the same, playing the role of clamping the two rotating frames 21 to the first winding frame 1 and the second winding frame 12 respectively; When assembling multiple first winding rollers 14 and second winding rollers 15, due to the deviation in the installation positions of the multiple first winding rollers 14 and second winding rollers 15 before clamping, it is difficult to clamp the multiple first winding rollers 14 and second winding rollers 15. By using multiple arc blocks 4 to be respectively slidably connected to the first winding frame 1 and the second winding frame 12, and supporting the bottom of the arc blocks 4 with first springs 41, during the assembly process of the first winding roller 14, the multiple arc blocks 4 can be first extruded. The multiple arc blocks 4 extrude the first springs 41 to contract and be stressed until the first winding roller 14 slides to the installation position. The first springs 41 elastically reset and extrude the arc blocks 4 to snap into the arc grooves, which can pre-limit the installation position of the first winding roller 14. The same operation is performed for the pre-limitation of the second winding roller 15. After pre-limiting the multiple first winding rollers 14 and second winding rollers 15, the multiple first limiting blocks 13 can be extruded to clamp and fix the multiple first winding rollers 14 and second winding rollers 15, reducing the situation of position deviation when the multiple first winding rollers 14 and second winding rollers 15 are clamped, and playing a role in pre-limiting the multiple first winding rollers 14 and second winding rollers 15; When calendering and winding plastic films of multiple widths, by using the magnetic attraction between the first magnetic strip 5 and the second magnetic strip, the multiple baffles 51 are respectively fixed on both sides of the multiple first winding rollers 14 and second winding rollers 15. The multiple baffles 51 can block both sides of the multiple first winding rollers 14 and second winding rollers 15, so that the wound plastic film can be limited between the two baffles 51, reducing the serious deviation of the plastic film during winding; when the two baffles 51 are sleeved on both sides of the first winding roller 14 and magnetically fixed, by using the extrusion insert block 22 to extrude the multiple first limiting blocks 13 to insert into the inside of the first winding roller 14, the multiple first limiting blocks 13 limit the first winding roller 14. While the first limiting blocks 13 slide, immediately extrude the third plugging rod 6 to slide and snap into the inside of the baffle 51. The two third elastic members 61 on both sides of the third plugging rod 6 are extruded and contracted to be stressed, realizing the function of clamping and limiting the baffle 51, and reducing the occurrence of the situation that the two baffles 51 are thrown off during the winding of the plastic film; After the plastic film is calendered and coiled, stop winding the plastic film, release the clamping connection between the rotating frame 21 and the first winding frame 1, and rely on the electric displacement component to drive the rotating frame 21 on the first support base 2 to slide away from the first winding frame 1, so that the extrusion insert block 22 is pulled out of the inside of the first winding frame 1, and the limitation of the plurality of first limiting blocks 13 on the plurality of first winding rollers 14 is released. The plurality of pull plates 7 slide along with the rotating frame 21, and the protrusions on the pull plates 7 cooperate to pull the plurality of first winding rollers 14 on the first winding frame 1 to slide, automatically discharging the plurality of first winding rollers 14 after winding the plastic film from the first winding frame 1. Subsequently, rotate the plurality of first winding rollers 14 located on the plurality of pull plates 7, and the inner walls of the plurality of first winding rollers 14 squeeze the plurality of friction pads 71 to deform until the protrusions on the plurality of pull plates 7 correspond to the plurality of mating holes 72, so that the first winding rollers 14 after winding the plastic film can be removed from the plurality of pull plates 7. The second winding roller 15 is discharged in the same way, which plays a role in discharging the first winding roller 14 and the second winding roller 15 after winding the plastic film; when winding the plastic film, the width between the two baffles 51 on the first winding roller 14 is suitable for the short extrusion plate 85 to be fitted and extruded, and the width between the two baffles 51 on the second winding roller 15 is suitable for the long extrusion plate 85 to be fitted and extruded. Moreover, the long extrusion plate 85 is supported by two or more fixing blocks 82. According to the different widths of the plastic film wound by the plurality of first winding rollers 14 and the second winding roller 15, the adapted extrusion plate 85 is adaptively installed and extruded to improve the anti-loosening effect of the extrusion plate 85 on the plastic film roll; When the plastic film is being wound, if the plastic film is cut off by the cutter, it is easy to cause the plastic film roll to become loose. The plurality of first clamping blocks 8 are clamped and fixed on the pushing assembly. The pressing plate 85 is clamped on the fixed block 82 through the second clamping block 84 and the second spring. The pressing plate 85 fits between the two baffles 51. As the plastic film continues to be wound, the plastic film roll becomes thicker and thicker on the first winding roller 14. The plastic film roll presses against the pressing plate 85, and the pressing plate 85 continuously presses the sliding rod 81 to slide. The fourth elastic member 83 is compressed and contracted under force. The pressing plate 85 closely adheres to the plastic film roll. After the cutter cuts off the plastic film, the pressing plate 85 can tightly press the cut plastic film on the plastic film roll, reducing the loosening of the plastic film roll. At the same time, a triggering assembly can be installed at the pressing plate 85. When the plastic film roll reaches the set winding thickness, the triggering assembly on the pressing plate 85 is squeezed and triggered to stop the continuous winding of the plastic film, warning the personnel to check and collect the plastic film roll, playing a role in reminding the material collection. When the plastic film is being wound, since the required winding amounts of the plastic film for each customer are different, the sliding seat 9 is fixed on the second support seat 24 to support the electric push rod 91. The output end of the electric push rod 91 drives the fixed frame 92 to slide, and the position of the fixed frame 92 is adjusted according to the thickness of the plastic film winding. The plurality of first clamping blocks 8 are clamped in the plurality of clamping grooves 93, and cooperate with the plurality of pressing plates 85 to press the plastic film roll. The position after the fixed frame 92 slides can adjust the pressing force of the plurality of pressing plates 85 on the plastic film roll, so that the pressing force of the plurality of pressing plates 85 on the plastic film roll can be adjusted according to the different winding amounts of the plastic film.
