Description

Technical Field

[0001] This invention relates to the field of silicone foam production technology, and in particular to a molding apparatus for the production and processing of liquid silicone foam. Background Technology

[0002] Liquid silicone foam, as a high-performance polymer foaming material, is widely used for sealing, shock absorption, and sound insulation in electronic devices, new energy vehicle batteries, and medical devices due to its excellent sealing, high and low temperature resistance, resilience, and insulation properties. During its production and molding process, to prevent the uncured liquid silicone raw material from sticking together during transportation and molding, and to maintain its cleanliness, a release film is usually applied to both the upper and lower surfaces of the material. Specifically, the mixed liquid silicone mixture is evenly coated onto a bottom release film through the flow channel of the mold head, and then a top release film is applied on top of the silicone layer. The coated silicone then enters the heating zone to form an extremely uniform and fine cell structure.

[0003] After the molding process is completed, the two release films need to be peeled off from the molded liquid silicone foam product for subsequent testing, die-cutting, assembly, or packaging. Currently, traditional production methods mostly rely on manual peeling. This method has many drawbacks: First, manual peeling is inefficient, restricting the overall efficiency of the production line; second, the peeling force and angle are difficult to control, and uneven force can easily cause the soft foam product to stretch, tear, or wrinkle, seriously affecting product yield; third, manual peeling makes it difficult to ensure the integrity of the release film, easily causing tearing or contamination, which is not conducive to the recycling and reuse of the release film. Summary of the Invention

[0004] The purpose of this invention is to provide a molding device for the production and processing of liquid silicone foam, which can automatically peel off the upper and lower release films of the molded silicone foam, thereby achieving the effect of recycling the release films.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a molding device for producing and processing liquid silicone foam, comprising a molding machine body and a processing frame disposed at the discharge port of the molding machine body, characterized in that: the processing frame is rotatably connected to a first guide roller and a first take-up roller in sequence along the silicone foam conveying direction, the silicone foam is wound onto the first take-up roller after being transmitted by the first guide roller, the processing frame is provided with two sets of peeling components located at the upper and lower ends of the first guide roller respectively, the peeling components comprising a peeling roller, a second guide roller and a second take-up roller rotatably connected to the processing frame in sequence along the release film conveying direction, the upper peeling component being used to peel off the upper release film of the silicone foam, and the lower peeling component being used to peel off the lower release film of the silicone foam.

[0006] By adopting the above technical solution, the main body of the molding machine includes a high-temperature drying tunnel. The silicone foam cured in the high-temperature drying tunnel is conveyed out of the high-temperature drying tunnel by a conveyor belt under the cover of two layers of release film. Then it passes through the first guide roller and the peeling roller in sequence. Since the peeling component is divided into upper and lower layers, the upper layer of release film is peeled off by the upper peeling roller when passing through the upper peeling component, and the lower layer of release film is peeled off by the lower peeling roller when passing through the lower peeling component. The peeled release film is guided by the second guide roller and then wound onto the second take-up roller, realizing the automated and uniform separation of the release film and the silicone foam. Compared with manual peeling, it is more stable and more efficient, and can better protect the physical integrity of the foam product and the release film. Moreover, the release film can be reused 2-3 times or more, which can effectively reduce material costs.

[0007] A further feature of the present invention is that: the peeling roller is fixed at both ends with a rotating shaft rotatably connected to the processing frame; the peeling roller is provided with a cooling cavity inside; a plurality of cooling pipes are fixed circumferentially inside the cooling cavity; and a liquid inlet pipe communicating with the plurality of cooling pipes is provided inside the rotating shaft.

[0008] By adopting the above technical solution, the external cooling medium enters the cooling pipe inside the cooling chamber through one end of the liquid inlet pipe and flows out from the other end of the liquid inlet pipe. When the release film after being peeled off passes through the peeling roller, it exchanges heat with the cooling medium to achieve cooling, which is beneficial to restoring the strength of the release film and helping it to remain intact in the subsequent automated peeling process, thereby improving its recycling value.

[0009] A further configuration of the present invention is as follows: the processing frame is provided with an ion nozzle located between the second guide roller and the second take-up roller and on the upper and lower sides of the release film, and an oscillating assembly for driving the ion nozzle to oscillate back and forth, wherein the air outlet of the ion nozzle is directly facing the release film.

[0010] By adopting the above technical solution, the release film, after being peeled off by the peeling roller, passes through the ion nozzle under the guidance of the second guide roller. The ion nozzle sends air onto the release film, which makes the release film more stable and neatly rolled up. At the same time, it can also blow away the tiny particulate pollutants attached to the film surface and assist in cooling. The swing component drives the ion nozzle to swing to expand the coverage of the ion air, effectively improving the static neutralization and cleaning uniformity.

[0011] A further configuration of the present invention is as follows: the processing frame is fixed with a mounting frame, the swing assembly includes a connecting frame fixed to the mounting frame, the mounting frame is fixedly mounted with a swing motor, the output end of the swing motor is fixed with a rocker arm, the connecting frame is provided with a swing groove, a connecting rod is hinged in the swing groove, the ion nozzle is fixed to the connecting rod, a sliding groove is fixed at the end of the connecting rod away from the ion nozzle, and a sliding rod that slides in the sliding groove is fixed at the end of the rocker arm away from the swing motor.

[0012] By adopting the above technical solution, the oscillating motor is started, which drives the rocker arm to rotate. The rocker arm then pushes the connecting rod to swing back and forth in the oscillating groove through the sliding rod and the sliding groove, thereby realizing the back and forth swinging air delivery of the ion nozzle and expanding the air delivery range.

[0013] A further feature of the present invention is that the mounting bracket is fixed with suction covers located on both sides of the ion nozzle, the suction covers are rotatably connected with a cleaning shaft, and the cleaning shaft is fixed with a cleaning plate that is in contact with the inner wall of the suction cover.

[0014] By adopting the above technical solution, the suction hood is connected to an external negative pressure fan through pipe fittings to capture loose pollutants blown up by the ion nozzle, ensuring the air cleanliness of the cleaning area and making the membrane cleaning process more efficient and reliable.

[0015] A further configuration of the present invention is as follows: a drive rod rotatably connected to the mounting bracket is fixed at the output end of the swing motor, the end of the drive rod is fixed to the rocker arm, a first pulley is fixed at one end of the cleaning shaft extending out of the suction cover, a second pulley is fixed on the drive rod, and a transmission belt is sleeved between the first pulley and the second pulley.

[0016] By adopting the above technical solution, when the swing motor is started, the swing motor drives the rocker arm to rotate through the drive rod, and at the same time drives the cleaning shaft to rotate through the first pulley, the second pulley and the transmission belt. The rotation of the cleaning shaft drives the cleaning plate to clean the contaminants attached to the inner wall of the suction hood in real time. The suction hood will capture the scraped contaminants again, which can further keep the release film clean.

[0017] A further feature of the present invention is that the suction cover has a through hole, the mounting bracket has a processing cover located above the through hole and whose bottom communicates with the through hole, and a knocking rod slides inside the processing cover. The bottom end of the knocking rod passes through the processing cover and the through hole and then knocks the cleaning plate.

[0018] By adopting the above technical solution, the hammer rod moves up and down inside the treatment hood to knock off the cleaning plate, shaking off the contaminants attached to the cleaning plate. The shaken-off contaminants are captured by the negative pressure fan and the suction hood, effectively maintaining the cleanliness of the overall cleaning structure, thereby further enhancing the cleanliness of the release membrane.

[0019] A further configuration of the present invention is as follows: a first bevel tooth is fixed on the cleaning shaft; a first connecting shaft is rotatably connected to the processing cover; a second bevel tooth meshing with the first bevel tooth is fixed at one end of the first connecting shaft; a cam located inside the processing cover is fixed at the other end; a cavity is provided inside the knocking rod; a first slider slides inside the cavity; an insertion hole is provided on the knocking rod; a second connecting shaft passing through the insertion hole is fixed to the first slider; a connecting rod is hinged between the second connecting shaft and the cam; a first spring is fixed between the upper and lower ends of the first slider and the inner wall of the cavity; a second slider sliding inside the processing cover is fixed to the outer wall of the knocking rod; a second spring is fixed between the upper and lower ends of the second slider and the inner wall of the processing cover.

[0020] By adopting the above technical solution, when the cleaning shaft rotates, the first bevel tooth drives the second bevel tooth and the first connecting shaft to rotate. Thus, the first connecting shaft drives the second connecting shaft to move up and down through the cam and connecting rod. The second connecting shaft pulls the knocking rod up and down inside the treatment hood through the first slider and the first spring. The end of the knocking rod reciprocates through the through hole to knock on the cleaning plate, realizing the self-cleaning of the cleaning plate. When the knocking rod moves up and down, the second slider moves up and down accordingly. The first spring and the second spring provide buffering and protection for the knocking rod, which helps to extend the service life of the device.

[0021] A further feature of the present invention is that the processing frame is rotatably connected to a dust-adhesive roller located between the suction hood and the second take-up roller and on the upper and lower sides of the release film.

[0022] By adopting the above technical solution, the release film is cleaned non-contactly by the ion nozzle and suction hood, and finally passes through the dust roller. The dust roller is used to remove the smallest particles that may remain in the previous step. This three-step cleaning process is more efficient and reliable, and can significantly extend the service life of the release film.

[0023] A further configuration of the present invention is as follows: adhesive paper is wound around the outside of the adhesive roller, and a third take-up roller for winding the adhesive paper is rotatably connected to the processing frame. The first take-up roller is driven to rotate by a first motor installed on the processing frame, the second take-up roller is driven to rotate by a second motor installed on the processing frame, and the third take-up roller is driven to rotate by a third motor installed on the processing frame.

[0024] By adopting the above technical solution, the outer side of the sticky paper is coated with a micro-adhesive layer to stick to dust and particles, while the inner side is a backing layer that is non-adhesive. When using the sticky roller, the outermost used sticky paper is wound and collected by the third take-up roller, while a new layer of clean sticky paper is automatically exposed to continue working, realizing the self-cleaning process of the sticky roller and improving the overall automated cleaning efficiency.

[0025] The beneficial effects of this invention are:

[0026] 1. The silicone foam cured in the high-temperature drying tunnel is conveyed out of the high-temperature drying tunnel by a conveyor belt under the cover of two layers of release film. Then it passes through the first guide roller and the peeling roller in sequence. The upper release film is peeled off by the upper peeling roller when it passes through the upper peeling component, and the lower release film is peeled off by the lower peeling roller when it passes through the lower peeling component. The peeled release film is guided by the second guide roller and then wound onto the second take-up roller. This realizes the automated and uniform separation of the release film and the silicone foam. Compared with manual peeling, it is more stable and more efficient, and can better protect the physical integrity of the foam product and the release film. Moreover, the release film can be reused 2-3 times or more, which can effectively reduce material costs.

[0027] 2. The cooling medium enters the cooling chamber through one end of the inlet pipe and flows out through the other end of the inlet pipe. When the release film is peeled off, it exchanges heat with the cooling medium as it passes through the peeling roller to achieve cooling, which helps to restore the strength of the release film and helps it remain intact in the subsequent automated peeling process, thereby improving its recycling value.

[0028] 3. The release film, after passing through the peeling roller, is guided by the second guide roller and passes through the ion air nozzle. The ion air nozzle sends air onto the release film, which makes the release film more stable and neat to be rolled up. At the same time, it can also blow away the tiny particulate pollutants attached to the film surface and assist in cooling.

[0029] 4. The suction hood is connected to an external negative pressure fan through pipe fittings to capture loose contaminants blown up by the ion nozzle, ensuring the air cleanliness of the cleaning area and making the membrane cleaning process more efficient and reliable.

[0030] 5. After the release film is cleaned non-contactly by the ion nozzle and suction hood, it finally passes through the dust roller. The dust roller is used to remove the smallest particles that may remain in the previous step. This three-step cleaning process is more efficient and reliable, and can significantly extend the service life of the release film. Attached Figure Description

[0039] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Example 1: A molding apparatus for producing and processing liquid silicone foam, such as... Figure 1-2As shown, the machine includes a molding machine body 1 and a processing frame 2 disposed at the discharge port of the molding machine body 1. The processing frame 2 is rotatably connected to a first guide roller 3 and a first take-up roller 4 along the conveying direction of the silicone foam 35. After being conveyed by the first guide roller 3, the silicone foam 35 is wound onto the first take-up roller 4. The processing frame 2 is provided with two sets of peeling components located at the upper and lower ends of the first guide roller 3, respectively. The peeling components include a peeling roller 5, a second guide roller 6 and a second take-up roller 7 rotatably connected to the processing frame 2 along the conveying direction of the release film 36. The upper peeling component is used to peel off the upper release film 36 of the silicone foam 35, and the lower peeling component is used to peel off the lower release film 36 of the silicone foam 35. The molding machine body 1 includes a high-temperature drying tunnel. The silicone foam 35, which is cured in the high-temperature drying tunnel, is conveyed out of the high-temperature drying tunnel under the cover of two layers of release film 36. Then, it passes through the first guide roller 3 and the peeling roller 5 in sequence. Since the peeling component is divided into two layers, the upper layer release film 36 is peeled off by the upper peeling roller 5 when passing through the upper peeling component, while the lower layer release film 36 is peeled off by the lower peeling roller 5 when passing through the lower peeling component. The peeled release film 36 is guided by the second guide roller 6 and then wound onto the second take-up roller 7. This realizes the automated and uniform separation of the release film 36 and the silicone foam 35. Compared with manual peeling, it is more stable and more efficient, and can better protect the physical integrity of the foam product and the release film 36.

[0041] like Figure 1-2 As shown, the peeling roller 5 has rotating shafts 8 fixed at both ends and rotatably connected to the processing frame 2. The peeling roller 5 has a cooling chamber 9 inside, with multiple cooling pipes 10 fixed circumferentially inside the cooling chamber 9. An inlet pipe 11 connected to the multiple cooling pipes 10 is provided inside the rotating shaft 8. External cooling medium enters the cooling pipes 10 inside the cooling chamber 9 through one end inlet pipe 11 and flows out from the other end inlet pipe 11. When the peeled release film 36 passes through the peeling roller 5, it exchanges heat with the cooling medium to achieve cooling, which helps restore the strength of the release film 36 and helps it remain intact in subsequent automated peeling processes.

[0042] like Figure 3-4 As shown, the processing frame 2 is equipped with ion nozzles 12 located between the second guide roller 6 and the second take-up roller 7, and positioned above and below the release film 36. A swing assembly 13 drives the ion nozzles 12 to swing back and forth. The air outlet of the ion nozzles 12 faces the release film 36. The release film 36, guided by the second guide roller 6 after passing through the peeling roller 5, passes through the ion nozzles 12. The ion nozzles 12 deliver air onto the release film 36, enabling it to be more stably and neatly wound up. Simultaneously, it blows away tiny particulate contaminants adhering to the film surface and assists in cooling. The swing assembly 13 drives the ion nozzles 12 to swing, expanding the ion air coverage area and effectively improving static neutralization and cleaning uniformity.

[0043] As shown in Figures 3-4, the processing frame 2 is fixed with a mounting frame 14. The swing assembly 13 includes a connecting frame 131 fixed to the mounting frame 14. A swing motor 132 is fixedly mounted on the mounting frame 14. A rocker arm 133 is fixed to the output end of the swing motor 132. The connecting frame 131 is provided with a swing groove 134. A connecting rod 135 is hinged in the swing groove 134. An ion nozzle 12 is fixed to the connecting rod 135. A sliding groove 136 is fixed to the end of the connecting rod 135 away from the ion nozzle 12. A sliding rod 137 that slides in the sliding groove 136 is fixed to the end of the rocker arm 133 away from the swing motor 132. When cleaning the release film 36, the swing motor 132 is started, causing the swing motor 132 to drive the rocker arm 133 to rotate. The rocker arm 133 pushes the connecting rod 135 to swing back and forth in the swing groove 134 through the sliding rod 137 and the sliding groove 136, realizing the back and forth swing air delivery of the ion nozzle 12 and expanding the air delivery range.

[0044] like Figure 3-4 As shown, the mounting bracket 14 is fixed with suction hoods 15 located on both sides of the ion nozzle 12. The suction hoods 15 are rotatably connected to a cleaning shaft 16, and the cleaning shaft 16 is fixed with a cleaning plate 17 that is in contact with the inner wall of the suction hood 15. The suction hoods 15 are connected to an external negative pressure fan through pipes to capture loose pollutants blown up by the ion nozzle 12, ensuring the air cleanliness of the clean area.

[0045] like Figure 4 As shown, the output end of the swing motor 132 is fixed with a drive rod 37 rotatably connected to the mounting bracket 14. The end of the drive rod 37 is fixed to the rocker arm 133. The cleaning shaft 16 extends out of the suction hood 15 and is fixed with a first pulley 38. A second pulley 39 is fixed on the drive rod 37. A transmission belt 40 is sleeved between the first pulley 38 and the second pulley 39. The swing motor 132 drives the rocker arm 133 to rotate through the drive rod 37. At the same time, it drives the cleaning shaft 16 to rotate through the first pulley 38, the second pulley 39 and the transmission belt 40. The rotation of the cleaning shaft 16 drives the cleaning plate 17 to clean the contaminants attached to the inner wall of the suction hood 15 in real time, realizing the self-cleaning of the inside of the suction hood 15. The suction hood 15 recaptures the scraped contaminants, which can further keep the release film 36 clean.

[0046] like Figure 5-6 As shown, the suction hood 15 has a through hole 41. The mounting bracket 14 fixes a treatment hood 42 located above the through hole 41, with its bottom communicating with the through hole 41. A knocking rod 43 slides inside the treatment hood 42. The bottom end of the knocking rod 43 passes through the treatment hood 42 and the through hole 41 and then knocks on the cleaning plate 17. The knocking rod 43 moves up and down inside the treatment hood 42 to knock on the cleaning plate 17, shaking off the contaminants attached to the cleaning plate 17. The shaken-off contaminants are captured by the negative pressure fan and the suction hood 15, realizing the self-cleaning of the cleaning plate 17, effectively maintaining the cleanliness of the overall cleaning structure, thereby further enhancing the cleanliness of the release membrane 36.

[0047] like Figure 5-6 As shown, a first bevel tooth 18 is fixed on the cleaning shaft 16, and a first connecting shaft 19 rotates on the treatment cover 42. A second bevel tooth 20 that meshes with the first bevel tooth 18 is fixed at one end of the first connecting shaft 19, and a cam 21 located inside the treatment cover 42 is fixed at the other end. A cavity 22 is provided inside the knocking rod 43, and a first slider 23 slides inside the cavity 22. An insertion hole is provided on the knocking rod 43, and a second connecting shaft 24 that passes through the insertion hole is fixed to the first slider 23. A connecting rod 25 is hinged between the second connecting shaft 24 and the cam 21. A first spring 26 is fixed between the upper and lower ends of the first slider 23 and the inner wall of the cavity 22. A second slider 27 that slides inside the treatment cover 42 is fixed to the outer wall of the knocking rod 43, and a second spring 28 is fixed between the upper and lower ends of the second slider 27 and the inner wall of the treatment cover 42. When the cleaning shaft 16 rotates, it drives the second bevel gear 20 and the first connecting shaft 19 to rotate through the first bevel gear 18. As a result, the first connecting shaft 19 drives the second connecting shaft 24 to move up and down through the cam 21 and the connecting rod 25. The second connecting shaft 24 pulls the knocking rod 43 up and down inside the treatment cover 42 through the first slider 23 and the first spring 26. The end of the knocking rod 43 reciprocates through the through hole 41 to knock on the cleaning plate 17, realizing the self-cleaning of the cleaning plate 17. When the knocking rod 43 moves up and down, the second slider 27 moves up and down accordingly. The first spring 26 and the second spring 28 provide buffering and protection for the knocking rod 43, which helps to extend the service life of the device.

[0048] Furthermore, the mounting bracket 14 is fixed with a protective cover that covers the drive rod 37, the first pulley 38, the second pulley 39, the transmission belt 40, the cleaning shaft 16, the first bevel gear 18, and the second bevel gear 20, etc., to protect the internal structure from the influence of the external environment and effectively extend the service life of the device.

[0049] like Figure 1-2As shown, the processing frame 2 is rotatably connected to a dust-adhesive roller 29 located between the suction hood 15 and the second take-up roller 7 and on the upper and lower sides of the release film 36. Dust-adhesive paper 30 is wound around the dust-adhesive roller 29. The processing frame 2 is rotatably connected to a third take-up roller 31 that takes up the dust-adhesive paper 30. The first take-up roller 4 is driven to rotate by a first motor 32 installed on the processing frame 2. The second take-up roller 7 is driven to rotate by a second motor 33 installed on the processing frame 2. The third take-up roller 31 is driven to rotate by a third motor 34 installed on the processing frame 2. After the release film 36 is cleaned non-contactly by the ion nozzle 12 and the suction hood 15, it finally passes through the sticky roller 29. The sticky roller 29 is used to remove the smallest particles that may remain in the previous step. This three-step cleaning process is more efficient and reliable. The sticky paper 30 has a micro-adhesive layer on the outer side to pick up dust and particles, while the inner side is a backing layer and is non-sticky. When using the sticky roller 29, the outermost used sticky paper 30 is wound and collected by the third take-up roller 31, while a new layer of clean sticky paper 30 is automatically exposed to continue working, realizing the self-cleaning process of the sticky roller 29 and improving the overall automated cleaning efficiency.

[0050] The first motor 32 drives the first take-up roller 4 to rotate and take up the silicone foam 35. During this process, the first guide roller 3 rotates and pulls the silicone foam 35. The second motor 33 drives the second take-up roller 7 to rotate and take up the release film 36. During this process, the second guide roller 6 rotates and pulls the release film 36. The third motor 34 drives the third take-up roller 31 to rotate and take up the used adhesive paper 30.
