Description

Technical Field

[0001] The present invention relates to the technical field of film forming, in particular to a functional film material forming device and a forming process. Background Art

[0002] Polymer film is a film made of organic polymers. With the development of petroleum industry and science and technology, the application field of polymer membranes has been continuously expanded, from the initial packaging film to intelligent polymer membranes, polymer functional membranes, etc. Among them, the most widely used is the selective separation membrane, such as ion exchange membrane, microporous filtration membrane, ultrafiltration membrane, liquid membrane, liquid crystal membrane, etc., which has been applied in the fields of nuclear fuel and metal refining, gas separation, seawater desalination, ultrapure water preparation, waste treatment, artificial organ manufacturing, medicine, food, agriculture, chemical industry and other aspects.

[0003] At present, there are multiple processes in the forming process of some films, and both extrusion and blow molding can be used to form the films. However, the current forming equipment is in a fixed position. When the film is being formed and extruded, the operator needs to pull the film at the end first, and the pulling needs to pass through multiple rollers. The prior art uses manual pulling of the end of the film from multiple rollers, and the equipment must be in operation at this time. At this time, there is a problem. The operator pulls from the running state of multiple rollers, and the hands can easily touch the running rollers. The operator may cause "hand jamming" or "hand rolling" due to improper operation, which poses a certain hazard to the safety of the operator. At the same time, in the current film forming process, many still use air cooling and cooling rollers. When the actual forming requires cooling of the film, many assembly lines are required to cool and roll it up. However, the high temperature generated by the film still surrounds the equipment, and the air cooling process is not uniform, resulting in a long assembly line required for film forming, and the equipment occupies a large area.

[0015] A forming process of a functional film material forming device comprises the following steps:

[0016] S1: Feeding, feeding the raw materials from the feeding port of the extrusion box;

[0017] S2: Hot melt extrusion. A heating module is provided inside the machine body to perform high-temperature hot melting on the raw materials inside the extrusion box. The melted raw materials will be extruded and transported along with the spiral blades, discharged from the position of the die outlet, and enter the interior of the cone sleeve. The heating module inside the machine body is used to hot melt the particles. When the particles are gradually converted into liquid, they are slowly extruded and transported to the position of the die outlet along with the extrusion of the spiral blades.

[0018] S3: Grinding extrusion. The left cone plate and the right cone plate will squeeze the liquid again to prevent some small particles from flowing out and reducing the quality of the film. Later, the rotation of the cone sleeve and the extrusion of the left cone plate will form a rolling effect to crush the small particles, ensure the quality of the discharged liquid, and improve the final film forming effect.

[0019] S4: Quick traction, manually pulling the film out of the shrinking roller assembly in the shrinking state and rolling it on the winding roller;

[0020] S5: Move and unfold, then the shrink frame will unfold automatically, and press multiple pressure rollers, upper cooling roller and lower cooling roller onto the film; since the threaded clamp is threadedly connected to the driving screw, the driving screw will drive the threaded clamp to move, and drive the fixed ring 2 and the rotating ring 2 to move left, while the fixed ring 1 and the rotating ring 1 are fixed in relative positions, and then as the fixed ring 2 and the rotating ring 2 move left, the shrink frame will be unfolded through the connection of the connecting frame, and after unfolding, the multiple pressure rollers on the shrink frame will form a combined pressure and stretching effect on the film, and the upper cooling roller and the lower cooling roller will be pressed downward, and by setting the different diameters, the film is in curved contact with the upper cooling roller and the lower cooling roller, thereby increasing the contact area and improving the cooling effect.

[0021] S6: Rotary cooling and winding. When the shrink frame is fully unfolded, the overall rotation of the shrink roller assembly will be controlled, thereby driving the entire film to perform self-rotational cooling and winding. After the overall unfolding, the rotating ring 2 will drive the entire shrink frame to rotate, thereby driving the film to rotate itself, which will produce a cooling effect on itself and improve the cooling efficiency.

[0022] Compared with the prior art, the present invention provides a functional film material forming device and forming process, which has the following beneficial effects:

[0023] 1. The functional film material forming equipment can be in a contracted state at the initial stage of the equipment through the setting of the contraction roller assembly, so that the operator only needs to put the newly produced film roll on the winding roller to achieve traction. After the contraction roller assembly is unfolded, the film can still be pressed and cooled, and the traction distance is very short, which is more convenient and quick, and improves the safety and convenience of the operator.

[0024] 2. The functional film material forming equipment can rotate when unfolding through the setting of the contraction roller assembly, and can realize winding and cooling during the rotation process. Compared with the traditional winding, this technical solution uses the film as a "fan blade", which can dissipate heat and cool itself during the rotation process, and can also dissipate heat to the surrounding environment, ensuring that the surrounding environment will not be in a high temperature state due to long-term winding, which is not conducive to the overall film cooling.

[0025] 3. This functional film material forming equipment reduces the footprint of the equipment by setting up a retractable shrinking roller assembly. At the same time, it utilizes its own rotational cooling characteristics to make the overall cooling effect better, and can achieve the corresponding cooling effect without an excessively long assembly line.

[0040] In this embodiment, the shrinking pressure roller assembly 5 includes a fixed ring 1 501 and a fixed ring 2 510, and the interiors of the fixed ring 1 501 and the fixed ring 2 510 are respectively provided with a rotating ring 1 502 and a rotating ring 2 511, and the rotating ring 1 502 and the rotating ring 2 511 are connected by a shrinking frame 504, and the shrinking frame 504 is provided with multiple pressure rollers, an upper cooling roller 506 and a lower cooling roller 507, and the fixed ring 2 510 is connected to the moving assembly 6; using the cross-type shrinking frame 504, the length of the equipment in the initial stage can be minimized, which is convenient for the operator to perform preliminary traction on the film, and after unfolding, the film can be effectively pressed and contacted to ensure its transportation stability, and according to the different designed pressure roller heights, the curved transportation of the film can be realized, and the upper cooling roller 506 and the lower cooling roller 507 will effectively cool the film in contact.

[0041] Furthermore, two groups of shrinkage frames 504 are provided, one group has two, and the two groups of shrinkage frames 504 are symmetrically distributed with the center line of the fixed ring 1 501 as the symmetry axis, and the shrinkage frames 504 are composed of a plurality of arc-shaped connecting rods, and the two ends of the shrinkage frames 504 are rotatably connected to the rotating ring 1 502 and the rotating ring 2 511 through the connecting frame 505 respectively; considering that the entire shrinkage frame 504 is to be in a rotating state in the later stage, the arc-shaped shrinkage frame 504 can avoid direct structural interference, and the two groups of shrinkage frames 504 can provide a great degree of operating stability, and the operator can set it on the shrinkage frame 504 at the corresponding position height according to the designed pressure roller size; the interior of the upper cooling roller 506 and the lower cooling roller 507 are hollow, and low-temperature coolant is arranged inside; the low-temperature coolant arranged inside the upper cooling roller 506 and the lower cooling roller 507 can effectively ensure that the upper cooling roller 506 and the lower cooling roller 507 are in a low-temperature state, and the film is contact-cooled.

[0042] Furthermore, the film discharging component 4 includes a cone sleeve 403, one end of the cone sleeve 403 is rotatably connected to a turntable 402, the turntable 402 is rotatably connected to the end face of the extrusion box 3, a die outlet 401 is provided inside the turntable 402, the output end of the motor 2 is connected to a spiral blade, the outer wall of the spiral blade is fitted with the inner wall of the extrusion box 3, one end of the spiral blade is fixedly connected to a right cone plate 404 through an axis rod, one side of the right cone plate 404 is connected to a left cone plate 405 through a spring 406, a gap is provided between the right cone plate 404 and the cone sleeve 403, one side of the cone sleeve 403 is connected to a die outlet frame 407, a notch is provided at the port of the die outlet frame 407, one end of the spiral blade is fixedly connected to the turntable 402 through a connecting rod, the right cone plate 404 and the left cone plate 405 are both arranged inside the cone sleeve 403, an extrusion seam 408 is provided between the left cone plate 405 and the cone sleeve 403, and the left cone plate 405 is movable. It is connected to the right cone plate 404; with the extrusion of the spiral blades, the heated liquid is slowly extruded and transported to the position of the die outlet 401, and then enters the interior of the cone sleeve 403. At this time, the right cone plate 404 will rotate with the rotation of the spiral blades. Because the right cone plate 404 is connected to the spiral blades, the liquid will pass through the gap between the right cone plate 404 and the cone sleeve 403, and then spread in a cone shape to enter the interior of the die frame 407. After passing through the die frame 407, it will be squeezed out from the slot opened at the port of the die frame 407; the left cone plate 405 and the right cone plate 404 are set to squeeze the liquid again to prevent some small particles from flowing out and reducing the quality of the film. Later, the rotation of the cone sleeve 403 and the extrusion of the left cone plate 405 will form a rolling effect to crush the small particles to ensure the quality of the discharged liquid and improve the final film forming effect.

[0043] In addition, a clamping device is provided on the cone sleeve 403; the clamping device includes a bracket sleeve 409, the bracket sleeve 409 is fixed on the cone sleeve 403, one side of the bracket sleeve 409 is slidably connected with a driving rod 412, one end of the driving rod 412 is connected to a spring 2 411, one end of the spring 2 411 is connected to the inside of the bracket sleeve 409, and a power gear 410 is slidably connected to the turntable 402 through a key slot, one side of the power gear 410 is provided with a power slot 4101 used in conjunction with the driving rod 412, and the power gear 410 is connected to the moving component 6; when the movable sleeve 605 is squeezed and moved laterally, it will drive the movable sleeve 605 to move laterally. The connected moving frame 603 moves laterally, so that the retaining ring 601 drives the power gear 410 to move laterally for a short distance, so at this time the power groove 4101 on the power gear 410 will abut against the driving rod 412, and as the power gear 410 rotates, it will synchronously drive the bracket sleeve 409 to rotate, and the bracket sleeve 409 will drive the entire cone sleeve 403 to rotate, and during the rotation process, it will also drive the mold frame 407 to rotate, so the entire film now forms two states of extrusion and rotation, and the film's own rotation will have a cooling effect on itself, thereby improving the cooling efficiency.

[0044] In addition, the moving assembly 6 includes a snap ring 601, which is rotatably connected to one side of the power gear 410, and a moving frame 603 is fixedly connected to the snap ring 601, and the moving frame 603 is L-shaped. A driving screw 608 is slidably connected to the moving frame 603, and one end of the driving screw 608 is rotatably connected to the machine body 1. A movable sleeve 605 is slidably connected to the driving screw 608, and the movable sleeve 605 is connected to the moving frame 603. One end of the driving screw 608 is connected to a fixed gear 604, and a telescopic spring 606 is provided between the fixed gear 604 and the movable sleeve 605. The surface of the driving screw 608 is threadedly connected to a threaded clamping plate 607, and the threaded clamping plate 607 is installed between the fixed ring 2 510 and the rotating ring 2 511. The rotating ring 2 511 is provided with an annular groove, and the threaded clamping plate 607 is installed inside the annular groove; as the motor 2 continues to start, it will drive the rotation of the turntable 402, and the turntable 40 2 will synchronously drive the power gear 410 to rotate through the keyway, and through the intermediate gear 609, it will drive the driving screw 608 on the moving gear 602 to rotate, and then through the threaded connection method, the threaded clamping plate 607 will move back and forth, and the clamping effect of the threaded clamping plate 607 will drive the fixed ring 2 510 and the rotating ring 2 511 to move left. As the fixed ring 2 510 and the rotating ring 2 511 move left, the shrinking frame 504 will be unfolded through the connection of the connecting frame 505. After unfolding, the multiple pressure rollers on the shrinking frame 504 will form a combined pressure and stretching effect on the film, and the upper cooling roller 506 and the lower cooling roller 507 will be pressed downward, so the shrinking frame 504 will form a stretching effect at this stage.

[0045] It is worth noting that the driving screw is connected with a moving gear 602, which is connected to the power gear 410 through a connecting piece, and the moving gear 602 is fixed on the surface of the driving screw 608. The connecting piece includes a rotating shaft 611, and an intermediate gear 609 is slidably connected to the rotating shaft 611 through a keyway.

One end of the rotating shaft 611 is rotatably connected to the body 1, and the rotating shaft 611 is slidably connected to the moving frame 603. The intermediate gear 609 is located between the power gear 410 and the moving gear 602, and a lever 610 is clamped on one side of the intermediate gear 609. In the initial stage, the operator needs to control the movement of the lever 610 to drive the intermediate gear 609 to disengage from the power gear 410 to achieve power interruption, because the inside of the extrusion box 3 needs to run for a long time in the initial stage. After the film is extruded, the operator rolls the film on the winding roller 508 before the shrinking frame 504 can be extended; when the lever 610 is released, it is reset by the elastic force of the intermediate spring 612, and the intermediate gear 609 will be controlled to re-engage between the power gear 410 and the moving gear 602. After that, as the motor 2 continues to start, it will drive the turntable 402 to rotate, and the turntable 402 will synchronously drive the power gear 410 to rotate through the keyway to achieve power transmission.

[0046] It is worth noting that a driving gear sleeve 509 meshing with the fixed gear 604 is provided on the rotating ring 511, and the driving gear sleeve 509 is fixed on the rotating ring 511. Two clamping sleeves 514 are fixedly connected to the fixed ring 510. The clamping sleeves 514 are installed on the rotating ring 511. A fixed gear sleeve 513 is fixedly connected between the two clamping sleeves 514. A pinion 512 is meshed on the fixed gear sleeve 513. The pinion 512 is connected to a winding roller 508 through a shaft rod. The winding roller 508 is arranged on the shrinking frame 504. The driving screw rod 608 is rotatably connected to the shaft sleeve 503, and the shaft sleeve 503 is installed Installed between fixed ring 1 501 and rotating ring 1 502; during the rotation of rotating ring 2 511, the pinions 512 at both ends of the winding roller 508 will mesh and rotate on the fixed gear sleeve 513. Because the fixed gear sleeve 513 is fixed on the clamping sleeve 514, the position of the fixed gear sleeve 513 remains unchanged. Therefore, when the pinion 512 rotates, it will form self-rotation, thereby driving the winding roller 508 to rotate and realize automatic winding. Therefore, the whole realizes multiple processes, from traction to extension, and then to rotation, heat dissipation and winding. It is an integrated automatic operation without excessive human intervention. Example 2

[0047] A forming process of a functional film material forming device comprises the following steps:

[0048] S1: feeding, feeding the raw material from the feeding port of the extrusion box 3; the raw material particles of the film need to be fed from the feeding port of the extrusion box 3, and the conventional process uses granular raw materials.

[0049] S2: Hot melt extrusion. A heating module is provided inside the machine body 1 to perform high-temperature hot melt on the raw materials inside the extrusion box 3. The melted raw materials will be extruded and transported along with the spiral blades, discharged from the position of the die outlet 401, and enter the interior of the cone sleeve 403. The heating module inside the machine body 1 is used to hot melt the particles. When the particles are gradually converted into liquid, they are slowly extruded and transported to the position of the die outlet 401 along with the extrusion of the spiral blades.

[0050] S3: Grinding and extruding; the two left cone plates 405 and the right cone plate 404 are set to squeeze the liquid again to prevent some small particles from flowing out and reducing the quality of the film. Later, the rotation of the cone sleeve 403 and the extrusion of the left cone plate 405 form a grinding effect to grind the small particles to ensure the quality of the discharged liquid and improve the final film forming effect.

[0051] S4: Quick traction, manually pulling the film out from the shrinking pressure roller assembly 5 in the shrinking state and rolling it on the winding roller 508;

[0052] S5: Movement and expansion linkage, after which the shrinking frame 504 will automatically expand, and press multiple pressure rollers, the upper cooling roller 506 and the lower cooling roller 507 onto the film; since the threaded clamp 607 is threadedly connected to the driving screw 608, the driving screw 608 will drive the threaded clamp 607 to move, and drive the fixed ring 2 510 and the rotating ring 2 511 to move left, while the fixed ring 1 501 and the rotating ring 1 502 are fixed in a relative position, and then as the fixed ring 2 510 and the rotating ring 2 511 move left, the shrinking frame 504 will be expanded through the connection of the connecting frame 505, and after expansion, the multiple pressure rollers on the shrinking frame 504 will form a combined pressure and stretching effect on the film, and the upper cooling roller 506 and the lower cooling roller 507 will be pressed downward, and by setting the different diameters, the film is in curved contact on the upper cooling roller 506 and the lower cooling roller 507, thereby increasing the contact area and improving the cooling effect.

[0053] S6: Rotational cooling and winding. When the shrinking frame 504 is completely unfolded, the overall rotation of the shrinking roller assembly 5 will be controlled, thereby driving the entire film to perform self-rotational cooling and winding. After the overall unfolding, the rotating ring 2 511 will drive the entire shrinking frame 504 to rotate, thereby driving the film's own rotation, which will have a cooling effect on itself to a great extent, thereby improving the cooling efficiency. Compared with traditional winding, this technical solution regards the film as a "fan blade", which can dissipate heat and cool itself during the rotation process, and can also dissipate heat to the surrounding environment, ensuring that the surrounding environment will not be in a high temperature state due to long-term winding, which is not conducive to the overall film cooling.

[0054] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0055] Working principle: first, the raw material particles of the film need to be put into the feed port of the extrusion box 3, and then with the start of the motor 2, the particles will be extruded, and the heating module inside the body 1 will be used to heat-melt the particles. When the particles are gradually converted into liquid, they are slowly extruded and transported to the position of the die outlet 401 with the extrusion of the spiral blades, and then enter the inside of the cone sleeve 403. At this time, the right cone plate 404 will rotate with the rotation of the spiral blades. Because the right cone plate 404 is connected to the spiral blades, the liquid will pass through the gap between the right cone plate 404 and the cone sleeve 403, and then spread in a cone shape, and then enter the position of the extrusion gap 408, squeezing the left cone plate 405, and the left cone plate 405 will move right after being subjected to force to squeeze the spring 406 , so that the left cone plate 405 slides into the inside of the right cone plate 404, and then the liquid will flow out from the outlet of the cone sleeve 403 and enter the inside of the mold frame 407. After passing through the mold frame 407, it will be squeezed out from the slot opened at the port of the mold frame 407 to form a film. Then the operator will pull the film. During the pulling process, the film is directly pulled out slowly and then rolled on the winding roller 508. At this time, the pulling is completed. Then the operator needs to release the lever 610. All previous operations are based on the operator moving the lever 610 to the left, driving the intermediate gear 609 to disengage from the power gear 410. When the lever 610 is released, it is reset by the elastic force of the intermediate spring 612, which will control the intermediate gear 609 to re-engage with the power gear Between the wheel 410 and the moving gear 602, as the motor 2 continues to start, the turntable 402 will be driven to rotate, and the turntable 402 will synchronously drive the rotation of the power gear 410 through the keyway connection, and through the intermediate gear 609, the driving screw 608 on the moving gear 602 will be driven to rotate, and then through the threaded connection between the driving screw 608 and the threaded clamping plate 607, the threaded clamping plate 607 will be driven to move back and forth, and a slot is provided on the fixed ring 510, and the threaded clamping plate 607 is clamped on the slot with a key to limit it to lateral movement, and an annular groove is provided on the rotating ring 511, and the threaded clamping plate 607 is clamped inside the annular groove, so the rotating ring 511 can rotate At the same time, the threaded clamping plate 607 will drive it to move left and right, while the fixed ring 1 501 and the rotating ring 1 502 are fixed in relative positions. Then, as the fixed ring 2 510 and the rotating ring 2 511 move left, the shrinking frame 504 will be connected and expanded through the connecting frame 505. After expansion, the multiple pressure rollers on the shrinking frame 504 will form a combined pressure and stretching effect on the film, and the upper cooling roller 506 and the lower cooling roller 507 will be pressed down. By setting the different diameters, the film is in curved contact on the upper cooling roller 506 and the lower cooling roller 507, thereby increasing the contact area and improving the cooling effect. When the whole is expanded to the limit, the threaded clamping plate 607 will abut against the movable sleeve 605, and then squeeze the movable sleeve 605 to make it move left. After that,The threaded clamping plate 607 will be separated from the threaded section on the driving screw rod 608, so at this time the fixed ring 2 510 and the rotating ring 2 511 will not continue to move laterally. After the movable sleeve 605 is squeezed and moved laterally, it will drive the movable frame 603 connected thereto to move laterally, and then the clamping ring 1 601 drives the power gear 410 to move laterally a short distance. At this time, the power groove 4101 on the power gear 410 will abut against the driving rod 412. With the rotation of the power gear 410, and then through the indirect connection of the driving rod 412, it will synchronously drive the bracket sleeve 409 to rotate, and the bracket sleeve 409 will drive the entire cone sleeve 403 to rotate, and during the rotation process, it will also drive the mold frame 407 to rotate. Therefore, the entire film is now in two states of extrusion and rotation, and the film's own rotation will have a cooling effect on itself to a great extent, improve the cooling efficiency, and at the same time, when the shrink frame 504 is unfolded After opening, the driving gear sleeve 509 on the rotating ring 2 511 will form a meshing state with the fixed gear 604, so the power will be transmitted to the rotating ring 2 511, driving the winding roller 508 to rotate synchronously to avoid rotational distortion. During the rotation of the rotating ring 2 511, the pinions 512 at both ends of the winding roller 508 will mesh and rotate on the fixed gear sleeve 513. Because the fixed gear sleeve 513 is fixed on the clamping sleeve 514, the position of the fixed gear sleeve 513 is unchanged. Therefore, when the pinion 512 rotates, it will form self-rotation, thereby driving the winding roller 508 to rotate and realize winding. The purpose of the clamping sleeve 514 is to clamp the position of the rotating ring 2 511 to ensure that it can rotate without misalignment with the fixed ring 2 510. The clamping sleeve 514 is synchronously set on the fixed ring 1 501 and the rotating ring 1 502, and the effect is still the same, achieving clamping and ensuring that they are in a concentric state.
