[0025] See also Figure 1 and Figure 2 In one embodiment of the utility model application, a storage rack for plastic coils is disclosed, which includes a frame 100, a lower roller platform 200, a traction assembly 400 and an upper roller platform 500, wherein the lower roller platform 200 is arranged at the bottom of the frame 100, and a plurality of lower roller shafts 300 are arranged on the lower roller platform 200 at intervals; the traction assembly 400 is arranged on the top of the frame 100; the upper roller platform 500 is arranged opposite to the lower roller platform 200, and the upper roller platform 500 is provided with a plurality of lower roller shafts 300; the traction assembly 400 is arranged on the top of the frame 100; the upper roller platform 500 is arranged opposite to the lower roller platform 200, and the upper roller platform 500 is provided with a plurality of lower roller shafts 300; the traction assembly 400 is arranged on the top of the frame 100; the upper roller platform 500 is provided with a plurality of lower roller shafts 3 ... A plurality of upper roller shafts 600 are arranged at intervals, and the upper roller shafts 600 are arranged alternately with the lower roller shafts 300; the traction assembly 400 is connected to the upper roller platform 500 to suspend the upper roller platform 500 above the lower roller platform 200; a longitudinal guide rail 700 is provided on the frame 100, and a guide wheel 800 is provided on the upper roller platform 500 corresponding to the longitudinal guide rail 700, and the guide wheel 800 rolls on the longitudinal guide rail 700 to constrain the upper roller platform 500.

[0026] The storage rack for plastic coils disclosed in this embodiment is used at the end of the plastic coil processing production line and is arranged before the winding roller of the coil; the plastic film is passed through the upper roller shaft 600 and the lower roller shaft 300 in an S shape. When the winding roller is replaced, the production line does not stop to replace the winding roller, and the upper roller platform 500 is gradually raised by the traction component 400, so that the distance between the upper roller shaft 600 and the lower roller shaft 300 is increased, thereby increasing the length of the plastic film arranged between the upper roller shaft 600 and the lower roller shaft 300, so as to achieve the effect of temporarily storing the coil. In this embodiment, the longitudinal guide rail 700 arranged on the frame 100 cooperates with the guide wheel 800 arranged on the upper roller platform 500 to constrain the upper roller platform 500, so that the upper roller platform 500 can only be lifted and lowered, and maintains sufficient stability during the lifting process to avoid swinging, reduce the pulling of the plastic film, and prevent the plastic coil from being deformed, damaged or torn, which is conducive to improving the yield rate of the coil.

[0027] Specifically, it should be noted that the storage rack for plastic coils disclosed in this embodiment can be used in the processing and production of plastic films such as polyvinyl chloride (PVC) film, polyethylene (PE) film, polypropylene (PP) film, and polystyrene (PS) film; of course, the protection scope of the present utility model is not limited to this, and the storage rack for plastic coils can also be used in the processing technology of films made of other resins. As long as the technical effect disclosed in this application can be achieved, it should also be within the scope of protection of this application as an equivalent replacement of the concept of the present utility model.

[0028] like Figure 1 As shown, as another implementation of this embodiment, the frame 100 is disclosed to include a horizontally arranged lower frame 110 and an upper frame 120, and a plurality of connecting columns 130 vertically arranged around the lower frame 110 and the upper frame 120, the lower roller platform 200 is arranged on the lower frame 110, and the traction assembly 400 is arranged on the upper frame 120; the upper roller platform 500 is suspended between the upper frame 120 and the lower frame 110; and the longitudinal guide rail 700 is arranged on the connecting column 130.

[0029] The lower frame 110 disclosed in this embodiment carries the lower roller platform 200, and multiple lower roller shafts 300 are arranged at intervals on the lower roller platform 200; the connecting column 130 extends vertically upward and is connected to the upper frame 120, fixing the upper frame 120 directly above the lower roller platform 200; therefore, the traction assembly 400 arranged on the upper frame 120 can suspend the upper roller platform 500 directly above the lower roller platform 200, and the upper roller shaft 600 and the lower roller shaft 300 are arranged correspondingly and arranged in a staggered manner to facilitate the S-shaped winding of the plastic film. Among them, the connecting column 130 not only plays the role of connecting and fixing the upper frame 120 and the lower frame 110, so that the overall structure of the frame 100 is stable; and a longitudinal guide rail 700 can be set. Through the assembly of the longitudinal guide rail 700 and the guide wheel 800, the upper roller platform 500 is constrained, so that the upper roller platform 500 reduces horizontal swing and only maintains free lifting in the vertical direction, thereby improving stability and reducing the pulling of the plastic film during the storage process.

[0030] Specifically, the lower frame 110, the upper frame 120 and the connecting column 130 disclosed in this embodiment can be fixed by welding, or by drilling holes and then screwing with bolts.

[0031] Specifically, as another implementation mode of this embodiment, it is disclosed that the shape of the lower frame 110 and the upper frame 120 are both rectangular, and there are four connecting columns 130. The four connecting columns 130 are respectively arranged at the four corners of the upper frame 120 and the lower frame 110, and the four connecting columns 130 together form a lifting space; the upper roller platform 500 is arranged in the lifting space, and the traction assembly 400 is used to drive the upper roller platform 500 to move up and down in the lifting space.

[0032] The frame 100 disclosed in this embodiment is a rectangular parallelepiped frame as a whole, the lower frame 110 and the upper frame 120 are both rectangular, the lower rollers 300 on the lower frame 110 are arranged side by side along the length direction of the lower frame 110, and the upper rollers 600 on the upper frame 120 are arranged side by side along the length direction of the upper frame 120. Generally speaking, the upper rollers 600 are arranged in parallel with the lower rollers 300, and the plastic film is fed in from the width direction of the lower frame 110, alternately bypassing each lower roller 300 and upper roller 600, and arranged in an S shape. Four connecting columns 130 are arranged at the four corners of the lower frame 110 to form a lifting space, surround the upper roller platform 500, protect the upper roller platform 500, prevent the upper roller platform 500 from shaking, and keep the upper roller 600 directly above the lower roller 300 without deviation, so as to avoid excessive pulling of the plastic film.

[0033] For example Figure 1 As shown, as another implementation of this embodiment, the upper roller platform 500 is disclosed to include a square body 510, a plurality of connecting plates 530 and four guide frames 520, wherein the square body 510 is connected to the traction assembly 400; a plurality of connecting plates 530 are arranged below the square body 510, and a plurality of connecting plates 530 are symmetrically distributed on both sides of the square body 510; an upper roller shaft 600 is arranged between each pair of connecting plates 530; the four guide frames 520 are all arranged on the top surface of the square body 510, and the four guide frames 520 are respectively located at the four corners of the square body 510; and each guide frame 520 is provided with a guide wheel 800.

[0034] The bottom surface of the upper roller platform 500 disclosed in this embodiment faces the lower roller shaft 300, and a connecting plate 530 is arranged on the lower side of the square main body 510 to connect the upper roller shaft 600, so that the upper roller shaft 600 can be closer to the lower roller shaft 300 and accurately staggered with the lower roller shaft 300. When the storage rack for plastic coils does not store plastic film, the upper roller platform 500 is lowered to the lowest end, and the connecting plate 530 is inserted into the gap between two adjacent lower roller shafts 300, so that the upper roller shaft 600 is almost in the same plane as the lower roller shaft 300. At this time, the length of the plastic film wound on the upper roller shaft 600 and the lower roller shaft 300 is extremely short, and the plastic film can quickly pass through the storage rack for plastic coils so as to be collected by the winding roller.

[0035] The four guide frames 520 disclosed in this embodiment are all provided with longitudinal guide rails 700, and four guide frames 520 are provided at the four corners of the square body 510 to fix four guide wheels 800, so that when the traction assembly 400 pulls the square body 510 to rise or fall, the four guide wheels 800 are respectively subjected to support forces in four directions, and the four support forces offset each other, thereby maintaining the stability of the square body 510, reducing the swing of the upper roller platform 500 in the horizontal direction, and not affecting the up and down movement of the square body 510 in the vertical direction.

[0036] For example Figure 1 As shown, as another implementation of this embodiment, each corner of the square body 510 is provided with a through hole that passes through from top to bottom; the traction assembly 400 includes a driving member 410, a first pulling structure 420, a second pulling structure 430 and a transmission structure 440, the driving member 410 is arranged on the upper frame 120; the first pulling structure 420 is arranged on the upper frame 120, and is transmission-connected to the output end of the driving member 410; the second pulling structure 430 is arranged on the upper frame 120, and is transmission-connected to the output end of the driving member 410; the second pulling structure 430 is arranged on the upper frame 120, and is transmission-connected to the first pulling structure 420. 0 are arranged side by side; the second pulling structure 430 and the first pulling structure 420 are respectively arranged at the upper left and upper right of the square body 510; and the second pulling structure 430 and the first pulling structure 420 are respectively assembled in different through holes for pulling the square body 510; the transmission structure 440 is arranged on the upper frame 120, one end of which is connected to the first pulling structure 420, and the other end is connected to the second pulling structure 430, for synchronously transmitting the second pulling structure 430 and the first pulling structure 420.

[0037] The traction assembly 400 disclosed in this embodiment is used to pull the upper roller platform 500. The upper roller platform 500 is provided with a plurality of upper roller shafts 600, so the overall weight is relatively large. In this embodiment, a motor can be used as a driving member 410, and the motor is precisely controlled to drive the first pulling structure 420 and the second pulling structure 430 to synchronously pull the two sides of the upper roller platform 500, so that the upper roller platform 500 can be lifted and lowered smoothly. The first pulling structure 420 and the second pulling structure 430 are connected by the transmission structure 440 to work synchronously, which can reduce the number of driving members 410, and is conducive to pulling the two sides of the upper roller platform 500 at the same time, avoiding the occurrence of uneven force on the two sides of the upper roller platform 500.

[0038] like Figure 2 As shown, as another implementation of this embodiment, the first pulling structure 420 is disclosed to include a first rotating shaft 421, a first sprocket 422 and a first chain 423. The first rotating shaft 421 is arranged on the upper frame 120 and is drivingly connected to the output end of the driving member 410; the first rotating shaft 421 is arranged in parallel with the upper roller shaft 600; the first sprocket 422 is arranged on the first rotating shaft 421 and is located directly above the through hole on one side of the square body 510; one end of the first chain 423 is sleeved on the first sprocket 422, and the other end is inserted into the through hole and connected to the square body 510;

[0039] The second pulling structure 430 includes a second rotating shaft 431, a second sprocket 432 and a second chain 433. The second rotating shaft 431 is arranged on the upper frame 120 and is arranged parallel to the first rotating shaft 421; the second sprocket 432 is arranged on the second rotating shaft 431 and is located directly above the through hole on the other side of the square body 510; one end of the second chain 433 is sleeved on the second sprocket 432, and the other end is inserted into the through hole and connected to the square body 510.

[0040] In this embodiment, transmission is achieved by means of chains and sprockets. By utilizing the high-precision transmission effect of the sprockets and chains, the rotation angles of the first sprocket 422 and the second sprocket 432 can be accurately controlled according to the rotation angles of the first rotating shaft 421 and the second rotating shaft 431, thereby accurately controlling the lifting height of the upper roller platform 500. Moreover, as long as the first sprocket 422 and the second sprocket 432 rotate at a uniform speed, the upper roller platform 500 can be driven to rise and fall at a uniform speed, thereby improving the stability of the upper roller platform 500 when moving, and avoiding pulling of the plastic film due to excessive acceleration.

[0041] Specifically, as another implementation manner of the present embodiment, it is disclosed that two first sprockets 422 are provided, and the two first sprockets 422 are respectively located on the first rotating shaft 421 at positions corresponding to the two through holes on a single side of the square body 510; two first chains 423 are provided, and the two first chains 423 are respectively sleeved on the two first sprockets 422; two second sprockets 432 are provided, and the two second sprockets 432 are respectively located on the second rotating shaft 431 at positions corresponding to the two through holes on a single side of the square body 510; two second chains 433 are provided, and the two second chains 433 are respectively sleeved on the two second sprockets 432.

[0042] In this embodiment, two first chains 423 and two second chains 433 are provided to connect the four corners of the square body 510 . During the pulling process, pulling force is applied to the four corners of the square body 510 at the same time, which is beneficial to further improve the stability of the upper roller platform 500 in lifting and lowering.

[0043] For example Figure 2 As shown, as another implementation of this embodiment, a first transmission plate 424 is provided on the first rotating shaft 421; a second transmission plate 434 is provided on the second rotating shaft 431; the transmission structure 440 includes a transmission shaft 441, a first crawler 442 and a first crawler 442, the transmission shaft 441 is arranged on the upper frame 120, and is arranged parallel to the first rotating shaft 421; a third transmission plate 444 and a fourth transmission plate 445 are respectively provided at both ends of the transmission shaft 441; the third transmission plate 444 and the first transmission plate 424 are arranged on the same vertical plane, and are connected by the first crawler 442; the fourth transmission plate 445 and the second transmission plate 434 are arranged on the same vertical plane, and are connected by the second crawler 443.

[0044] In this embodiment, a transmission disc and a track are provided and a purely mechanical transmission structure 440 is adopted to achieve a precise transmission effect. When the first rotating shaft 421 rotates, the driving force is transmitted to the transmission shaft 441 through the first track 442, and the transmission shaft 441 rotates synchronously. The same driving force is transmitted to the second rotating shaft 431 through the second track 443, and finally the second rotating shaft 431 rotates synchronously with the first rotating shaft 421, and the rotation angles are consistent, which is conducive to applying the same pulling force to both sides of the upper roller platform 500 to smoothly pull the upper roller platform 500 up or down.

[0045] Specifically, as another implementation of this embodiment, the longitudinal guide rail 700 is protrudingly arranged on the surface of the frame 100; a card slot is circumferentially arranged on the guide wheel 800, and the card slot is used to engage with the longitudinal guide rail 700.

[0046] The longitudinal guide rail 700 disclosed in this embodiment is protruding, and the slot of the guide wheel 800 is adapted to the longitudinal guide rail 700. Therefore, during the lifting process of the upper roller platform 500, the guide wheel 800 rolls on the longitudinal guide rail 700, and the side wall of the slot of the guide wheel 800 abuts against the side wall of the longitudinal guide rail 700. Constrained by the longitudinal guide rail 700, the guide wheel 800 can only roll up and down but will not swing horizontally; therefore, the entire upper roller platform 500 fixedly connected to the guide wheel 800 is constrained, thereby reducing swinging, improving the stability of lifting and lowering, reducing the tearing of the plastic film, and helping to improve the product yield.

[0047] It should be noted that the present embodiment only exemplifies the assembly method of the guide wheel 800 and the longitudinal guide rail 700. In other implementations of the present embodiment, the longitudinal guide rail 700 may also be recessed on the frame 100, and the guide wheel 800 is stuck in the longitudinal guide rail 700 and rolls, which can also play a guiding role and improve the stability of the upper roller platform 500 in lifting and lowering.

[0048] The present application also discloses a plastic coil processing device, which comprises a storage rack for the plastic coil as described above.

[0049] In summary, the present application discloses a storage rack for plastic coils, which includes a frame 100, a lower roller platform 200, a traction assembly 400 and an upper roller platform 500, wherein the lower roller platform 200 is arranged at the bottom of the frame 100, and a plurality of lower roller shafts 300 are arranged at intervals on the lower roller platform 200; the traction assembly 400 is arranged at the top of the frame 100; the upper roller platform 500 is arranged opposite to the lower roller platform 200, and a plurality of lower roller shafts 300 are arranged at intervals on the upper roller platform 500; A plurality of upper roller shafts 600 are arranged, and the upper roller shafts 600 and the lower roller shafts 300 are arranged alternately; the traction assembly 400 is connected to the upper roller platform 500 to suspend the upper roller platform 500 above the lower roller platform 200; a longitudinal guide rail 700 is provided on the frame 100, and a guide wheel 800 is provided on the upper roller platform 500 corresponding to the longitudinal guide rail 700, and the guide wheel 800 rolls on the longitudinal guide rail 700 to constrain the upper roller platform 500. The storage rack for plastic coils disclosed in this embodiment is used at the end of the plastic coil processing production line and is arranged before the winding roller of the coil; the plastic film is passed through the upper roller shaft 600 and the lower roller shaft 300 in an S shape. When the winding roller is replaced, the production line does not stop to replace the winding roller, and the upper roller platform 500 is gradually raised by the traction component 400, so that the distance between the upper roller shaft 600 and the lower roller shaft 300 is increased, thereby increasing the length of the plastic film arranged between the upper roller shaft 600 and the lower roller shaft 300, so as to achieve the effect of temporarily storing the coil. The longitudinal guide rail 700 arranged on the frame 100 cooperates with the guide wheel 800 arranged on the upper roller platform 500 to constrain the upper roller platform 500 so that the upper roller platform 500 can only be lifted and lowered. During the lifting process, sufficient stability is maintained to avoid swinging, reduce the pulling of the plastic film, and prevent the plastic coil from being deformed, damaged or torn, which is conducive to improving the yield rate of the coil.

[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.
