Description

Technical Field

[0001] This application relates to the field of embossed casting film machines, and more particularly to embossed casting film machines. Background Art

[0002] Casting is a plastic forming technology in which a solution of a polymer or a melt of a polymer is spread directly on a steel belt and steel rollers by a doctor blade or a die head to form an unoriented film of a certain thickness, which is divided into solvent casting and melt casting. And the casting film machine is the machine for producing this kind of film.

[0003] An automated film casting machine mentioned in the existing Chinese patent (Publication No.: CN216400277U) includes a bottom plate. Both sides of the bottom of the bottom plate are fixedly installed with brackets. One side of the bottom plate is rotatably connected to a first guiding roller through a connecting frame. The other side of the bottom plate is rotatably connected to a second guiding roller through a connecting frame. One side of the bracket near the bottom of the first guiding roller is rotatably connected to a feeding roller through a connecting frame. The other side of the bracket near the bottom of the second guiding roller is rotatably connected to a winding roller through a connecting frame. Through the cooperative setting among the driving motor, the rotating rod, and the stirring rod, the slurry in the mixing cylinder can be evenly stirred. Then, through the cooperative setting between the connecting rod and the scraper, the slurry on the mixing cylinder and the partition can be scraped off, avoiding the adhesion of the slurry on the mixing cylinder and the partition, facilitating the better discharge of the slurry in the mixing cylinder, and being relatively convenient to use.

[0004] In actual operation, after the film is produced and shaped, it will be directly wound onto the winding roller. During the winding process of the film, it will be in direct contact with the air, and floating dust in the air may float onto the film being wound and then be directly wound up, which may cause a reduction in the quality of the film roll. Summary of the Utility Model

[0005] The purpose of this application is to provide an embossed casting film machine to solve the problem that floating dust in the air may float onto the film being wound and then be directly wound up, which may cause a reduction in the quality of the film roll as mentioned in the above background art.

[0006] To achieve the above purpose, this application specifically adopts the following technical solutions:

[0007] The embossed casting film machine includes a casting machine body. On one side of the casting machine body, there is a winding roller. At both ends of the winding roller, there are two symmetrical support frames. The winding roller is rotationally connected to the support frames. One end of the winding roller is provided with a winding motor, and the winding motor is fixedly connected to the support frame. The output end of the winding motor penetrates through the support frame and is fixedly connected to the winding roller. On one side of the winding roller, there are two symmetrical limiting rollers I. Both ends of the limiting roller I are rotationally connected to the support frames. On one side of the limiting roller I, there are two symmetrical limiting rollers II. Both ends of the limiting roller II are rotationally connected to the support frames. Between the limiting roller I and the winding roller, there is a support plate. Between both ends of the support plate and the support frames, there is a support mechanism. Uniformly distributed soft brushes are fixed on the support plate. Between the limiting roller I and the support plate, there is a dust suction mechanism. Between the limiting roller I and the limiting roller II, there is a tensioning mechanism.

[0008] By adopting the above technical solution, the winding motor of the winding roller drives the winding roller to rotate, and the casting film is wound into a roll on the winding roller. During the winding process, the soft brushes on the support plate sweep away the floating dust on the casting film, and then it is sucked away by the dust suction mechanism, thereby reducing the possibility of floating dust in the air adhering to the casting film and then being wound up.

[0009] Further, the dust suction mechanism includes a dust suction nozzle arranged between the support plate and the limiting roller I. At both ends of the dust suction nozzle, there are two symmetrical support blocks II, and the support blocks II are fixedly connected to the support frames. A dust suction chamber is fixed on the dust suction nozzle, a dust suction fan is installed on the dust suction chamber, and a collection component is arranged on the dust suction chamber.

[0010] By adopting the above technical solution, the dust suction fan is started. The dust suction fan uses the dust suction nozzle of the dust suction chamber to suck away the cleaned floating dust and send it into the collection component, thereby reducing the possibility of dust accumulating on one side of the soft brush.

[0011] Further, the collection component includes a collection hose. One end of the collection hose is fixedly connected to the dust suction chamber, and the collection hose is communicated with the dust suction chamber. The end of the collection hose far from the dust suction chamber is threadedly connected with a support ring, and a filter screen is fixed on the support ring.

[0012] By adopting the above technical solution, the dust is sent into the collection hose by the dust suction fan and then filtered by the filter screen, thereby reducing the possibility of the dust coming out of the collection hose and floating in the air again.

[0013] Further, the support mechanism includes two support blocks I fixed at both ends of the support plate. Support grooves are opened on both support frames, and the support grooves correspond to the support blocks I. A limiting component is arranged on the support frames.

[0014] By adopting the above technical solution, the first support block is disengaged from the restriction of the limiting component, and then the first support block slides out of the support groove, so that the disassembly of the support plate can be facilitated, and the cleaning or replacement of the soft brush can be facilitated.

[0015] Further, the limiting component includes a limiting block, the limiting block is slidably connected to the support frame, a limiting spring is arranged between the limiting block and the support frame, and both ends of the limiting spring are fixedly connected to the limiting block and the support frame.

[0016] By adopting the above technical solution, when it is necessary to slide the first support block out of the support groove, the limiting block is moved, the limiting block presses the limiting spring, so that the limiting block is disengaged from the restriction of the support groove, and then the first support block slides out of the support groove, so that the disassembly and installation of the first support block on the support frame can be facilitated.

[0017] Further, an inclined block is fixed to one end of the limiting block away from the limiting spring, and the inclined surface of the inclined block faces the outside of the support groove.

[0018] By adopting the above technical solution, the first support block presses the inclined surface of the inclined block, the inclined block drives the limiting block to move, and when the first support block is disengaged from the inclined surface of the inclined block, the limiting block and the inclined surface block the support groove under the action of the limiting spring, so that the first support block can be conveniently inserted into the support groove.

[0019] Further, the tensioning mechanism includes a first tensioning roller, moving blocks are arranged at both ends of the first tensioning roller, the first tensioning roller is rotatably connected to the moving blocks, a second tensioning roller is arranged below the first tensioning roller, the second tensioning roller is rotatably connected to the moving blocks, and an adjusting component is arranged between the moving blocks and the support frame.

[0020] By adopting the above technical solution, the moving blocks drive the first tensioning roller and the second tensioning roller to move, and the first tensioning roller and the second tensioning roller pull the casting film passing between them, so that the casting film can be kept in a tight state, which facilitates the cleaning of the soft brush and reduces the possibility of wrinkles appearing during winding.

[0021] Further, the adjusting component includes a threaded rod rotatably connected to one of the support frames, the threaded rod is threadedly connected to the corresponding moving block, an adjusting motor is fixed to one of the support frames, the output end of the adjusting motor penetrates through the support frame and is fixedly connected to the threaded rod, and a sliding rod is fixed to the support frame far from the threaded rod among the two support frames, and the sliding rod is slidably connected to the corresponding moving block.

[0022] By adopting the above technical solution, the threaded rod rotates to drive the corresponding moving block to move, the moving block drives the first tensioning roller and the second tensioning roller, and the moving blocks at the other ends of the first tensioning roller and the second tensioning roller slide under the restriction of the sliding rod, so that the movement of the moving block can be made more convenient.

[0023] In summary, the present application includes at least one of the following beneficial effects;

[0024] 1. In the present application, during the winding process, the floating dust on the casting film is cleaned off by the soft brush on the support plate, and then the floating dust accumulates on one side of the soft brush. The dust suction fan is started, and the dust suction fan uses the dust suction nozzle of the dust suction bin to suck away the cleaned floating dust and send it into the collection component, achieving the purpose of reducing the dust attached to the surface of the casting film during winding and reducing the possibility of reducing the casting roll due to attached dust.

[0025] 2. In the present application, when winding the casting film, when the casting film becomes loose, the adjustment component is used to drive the moving block, and the moving block drives the tensioning roller 1 and the tensioning roller 2 to move. The tensioning roller 1 and the tensioning roller 2 pull the casting film passing between them, achieving the effect of higher cleaning when the casting film passes through the soft film brush and reducing the wrinkles that may be caused by winding the casting film.

[0032] The following is combined with the attached Figures 1-4A further detailed description of the present application is provided.

[0033] An embodiment of the present application discloses an embossing casting film machine.

[0034] Referring to Figure 1 、 Figure 2 and Figure 3 As shown in FIGS.

[0035] Referring to Figure 2 and Figure 3 As shown in FIGS.

[0036] Referring toFigure 2 and Figure 3 As shown in Figure 3 , the collection assembly 65 includes a collection hose 651. One end of the collection hose 651 is fixedly connected to the dust suction bin 63, and the collection hose 651 communicates with the dust suction bin 63. A support ring 652 is threadedly connected to the end of the collection hose 651 away from the dust suction bin 63, and a filter net 653 is fixed on the support ring 652. The dust entering the dust suction bin 63 is sent into the collection hose 651 by the dust suction fan 64, then drifts from the collection hose 651 to the filter net 653 on the support ring 652, and then is filtered by the filter net 653. By using the filter net 653 on the collection hose 651 for filtration, it is possible to reduce the possibility of dust coming out of the collection hose 651 and drifting in the air again.

[0037] Refer to Figure 1 and Figure 4 As shown in Figure 4 , the support mechanism 5 includes two first support blocks 51 fixed at both ends of the support plate 3. Support grooves 52 are formed on both support frames 2, the support grooves 52 correspond to the first support blocks 51, and a limit assembly 53 is arranged on the support frames 2. When it is necessary to clean or replace the soft brush 4, by using the limit assembly 53, the first support block 51 is released from the restriction of the limit assembly 53, and then the first support block 51 slides out of the support groove 52. The first support block 51 drives the support plate 3 to disengage from the support frame 2. By enabling the first support block 51 to be fixed in the support groove 52 on the support frame 2, the disassembly of the support plate 3 can be facilitated, and it is convenient to clean or replace the soft brush 4.

[0038] Refer to Figure 1 and Figure 4 As shown in Figure 4 , the limit assembly 53 includes a limit block 532. The limit block 532 is slidably connected to the support frame 2, and a limit spring 531 is arranged between the limit block 532 and the support frame 2. Both ends of the limit spring 531 are fixedly connected to the limit block 532 and the support frame 2. When the first support block 51 is in the support groove 52, the limit block 532 restricts the first support block 51 under the support of the limit spring 531. When it is necessary to slide the first support block 51 out of the support groove 52, the limit block 532 is moved. The limit block 532 compresses the limit spring 531, enabling the limit block 532 to release the restriction on the support groove 52, and then the first support block 51 slides out of the support groove 52. By using the blockage of the limit block 532 on the first support block 51, the disassembly and installation of the first support block 51 on the support frame 2 can be facilitated.

[0039] Refer to Figure 1 and Figure 4, one end of the limit block 532 away from the limit spring 531 is fixed with an inclined block 11, and the inclined surface of the inclined block 11 faces the outside of the support groove 52. When reinstalling the removed support block 51 into the support groove 52, first align the support block 51 with the support groove 52, then the support block 51 presses the inclined surface of the inclined block 11, then the inclined block 11 moves, the inclined block 11 drives the limit block 532 to move, and the limit block 532 presses the limit spring 531. When the support block 51 disengages from the inclined surface of the inclined block 11, the limit block 532 and the inclined surface block the support groove 52 under the action of the limit spring 531. By pressing the inclined surface of the inclined block 11 to make the inclined block 11 move, it is convenient for the support block 51 to enter the support groove 52.

[0040] Refer to Figure 1 and Figure 2 , the tensioning mechanism 7 includes a first tensioning roller 71. Moving blocks 73 are arranged at both ends of the first tensioning roller 71. The first tensioning roller 71 is rotatably connected to the moving blocks 73. A second tensioning roller 72 is arranged below the first tensioning roller 71. The second tensioning roller 72 is rotatably connected to the moving blocks 73. An adjusting assembly 74 is arranged between the moving blocks 73 and the support frame 2. When winding the cast film, when the cast film becomes loose, the adjusting assembly 74 is used to drive the moving blocks 73, the moving blocks 73 drive the first tensioning roller 71 and the second tensioning roller 72 to move, and the first tensioning roller 71 and the second tensioning roller 72 pull the cast film passing between them. By using the first tensioning roller 71 and the second tensioning roller 72 to tension the cast film, the cast film can be kept in a taut state, which facilitates the cleaning of the soft brush 4 and reduces the possibility of wrinkles during winding.

[0041] Refer to Figure 1 and Figure 2 , the adjusting assembly 74 includes a threaded rod 742 rotatably connected to one of the support frames 2. The threaded rod 742 is threadedly connected to the corresponding moving block 73. An adjusting motor 743 is fixed on one of the support frames 2. The output end of the adjusting motor 743 penetrates the support frame 2 and is fixed to the threaded rod 742. A sliding rod 741 is fixed on the support frame 2 of the two support frames 2 that is far from the threaded rod 742. The sliding rod 741 is slidably connected to the corresponding moving block 73. When it is necessary to adjust the positions of the first tensioning roller 71 and the second tensioning roller 72, start the adjusting motor 743. The adjusting motor 743 drives the threaded rod 742 to rotate. The threaded rod 742 rotates to drive the corresponding moving block 73 to move. The moving block 73 drives the first tensioning roller 71 and the second tensioning roller 72. The moving blocks 73 at the other ends of the first tensioning roller 71 and the second tensioning roller 72 slide under the restriction of the sliding rod 741. By using the rotation of the threaded rod 742 and the restriction of the sliding rod 741, the moving block 73 can move more conveniently.

[0042] Working principle: After the casting film is formed on the machine, the casting film is passed through between two limiting rollers II 9, then passed through between tension roller I 71 and tension roller II 72, and then passed through between two limiting rollers I 8, and then passes through the dust suction nozzle 61 and the soft brush 4 on the support plate 3, and finally wound on the winding roller 1. The winding motor 10 drives the winding roller 1 to rotate, and the casting film is wound into a roll on the winding roller 1. During the winding process, the soft brush 4 on the support plate 3 sweeps away the floating dust on the casting film, and then the dust suction fan 64 is started. The dust suction fan 64 uses the dust suction nozzle 61 of the dust suction bin 63 to suck away the cleaned floating dust and send it into the collection assembly 65. When the casting film becomes loose during the winding process, the adjustment motor 743 is started to drive the moving block 73, and the moving block 73 drives the tension roller I 71 and the tension roller II 72. The tension roller I 71 and the tension roller II 72 pull the casting film passing through between the tension roller I 71 and the tension roller II 72 to make the casting film taut, which is convenient for the soft brush 4 to clean, and then the casting film is wound by the winding roller 1 in a taut state.
