Description

Technical Field

[0001] The utility model relates to the technical field of plastic sheet extrusion molding manufacturing, in particular to a molding component and a cooling molding device with the molding component. Background Art

[0002] After the plastic sheet is manufactured by extrusion molding, it is usually at a high temperature, relatively soft in texture, and has an unstable shape. After the extruded plastic sheet is cooled and molded by a cooling and molding device, the shape of the sheet can be fixed. The existing cooling and molding device usually uses a molding component to mold the high-temperature plastic extruded sheet. The molding component includes a feed port, a molding channel, and a discharge port. The high-temperature plastic sheet extruded by the plastic extruder enters the molding channel through the feed port of the molding component for cooling and molding. The molded sheet is molded and discharged through the discharge port of the molding component. In this process, since the cooling effect of the two sides of the molding component is poorer than that of the rest of the plastic sheet, when the plastic sheet is cooled and molded by the molding component, the cooling speed of its side is inconsistent with that of the rest of the plastic sheet, the cooling is not uniform, and the molding effect is relatively poor. The side of the molded sheet product is more prone to wrinkles, warping and deformation than the rest of the sheet. Therefore, the molded product needs to perform an additional trimming process, which is not only cumbersome in terms of process, but also causes waste of material costs. Utility Model Content

Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction on the technical solution of the utility model.

[0034] See also Figure 1As shown, the utility model provides a cooling and shaping device 100 for plastic extruded sheets, which includes a shaping component 10, a shaping base 20, a lifting component 30 and a cooling component 40.

[0035] Please combine Figure 1 , Figure 3 As shown, the shaping assembly 10 includes two shaping plates 101 arranged in the up-down direction, and the shaping plate 101 on the lower side is fixedly supported on the shaping base 20. Specifically, the shaping plate 101 on the lower side is fixedly supported on the shaping base 20 by a support member 303, and the shaping plate 101 on the upper side is connected by a lifting assembly 30, so that the lifting assembly 30 can drive the shaping plate 101 on the upper side to perform a lifting action, so as to adjust the spacing size of the shaping channel 103 between the two shaping plates 101. The lifting assembly 30 can also drive the shaping plate 101 on the upper side to move up to a position away from the shaping plate 101 on the lower side, thereby opening the shaping channel 103, so that the plastic sheet after cooling and shaping can pass through the shaping channel 103 conveniently, thereby removing the shaped sheet product from the cooling and shaping device 100.

[0036] The lifting assembly 30 includes a lifting cylinder 301 installed on the shaping base 20, a lifting platform 302 located above the shaping assembly 10, and the bottom of the lifting platform 302 is connected to the cylinder shaft of the lifting cylinder 301, so that the lifting platform 302 can be lifted or lowered by the telescopic action of the cylinder shaft of the lifting cylinder 301, thereby realizing the lifting action. The shaping plate 101 located on the upper side is connected to the lifting assembly 30, specifically, the bottom of the lifting platform 302 is connected to the shaping plate 101 on the upper side through a connecting piece 304. When the lifting platform 302 is lifted or lowered, it can drive the shaping plate 101 on the upper side to perform the lifting action together, so as to adjust the spacing of the shaping channel 103 between the shaping plate 101 on the upper side and the shaping plate 101 on the lower side or open the shaping channel 103. Specifically, the spacing between the shaping channels 103 can be adjusted to adapt to the cooling and shaping of plastic high-temperature sheets of different thicknesses. After the shaping channels 103 are opened, the cooled plastic sheets can be quickly discharged, and the formed sheet products can be easily removed.

[0037] In order to facilitate the lifting platform 302 to achieve smooth lifting action, a guide rack 305 is provided on the shaping base 20, and a guide gear 306 is provided on the lifting platform 302. During the lifting action process of the lifting platform 302, the guide gear 306 is always meshed with the guide rack 305 for transmission cooperation.

[0038] In order to facilitate cooling of the shaping component 10 and thus facilitate rapid shaping of the plastic high-temperature sheet, a fluid channel is provided inside the shaping plate 101, and the cooling component 40 is connected to the fluid channel and configured to provide a driving force for the circulation of the cooling fluid in the fluid channel.

[0039] Specifically, the fluid channel may include a water channel 401 disposed inside the shaping plate 101, wherein the water channel 401 is suitable for passing cooling water, and an air channel 402 may also be disposed inside the shaping plate 101, and the air channel 402 is suitable for being connected to a negative pressure air source, thereby providing suction force, and facilitating the adsorption and shaping of the sheet product. In certain embodiments, other cooling fluid media may also be passed into the water channel 401, without specific limitation. The cooling assembly 40 may include some cooling fluid medium supply equipment, such as a cooling water tank for supplying cooling water, a cooling water pump, and necessary cooling pipes connected to the water channel 401, etc.; the negative pressure air source may include a negative pressure air pump, a vacuum compressor, and necessary suction air pipes connected to the air channel 402, etc., without specific limitation.

[0040] Combination Figure 3 , Figure 4 As shown, two opposite walls of the two shaping plates 101 are provided with a plurality of air grooves 1011 arranged in parallel or in parallel, and these air grooves 1011 are connected to the air channel 402. Due to the provision of these air grooves 402, the plastic high temperature sheet can be adsorbed and shaped in the shaping channel 103, which is convenient for rapid cooling and shaping.

[0041] Please combine Figure 1 , Figure 2 As shown, adsorption shaping members 105 for adsorbing and shaping the side edges of the plastic sheet are arranged on opposite sides of the shaping channel 103 .

[0042] During operation, when the plastic high-temperature sheet is cooled and shaped by the shaping component 10, the adsorption shaping part 105 can adsorb and shape the side of the plastic high-temperature sheet, thereby avoiding adverse conditions such as warping, deformation, and wrinkles on the side of the plastic high-temperature sheet. After the plastic sheet product is shaped, there is no need to perform a trimming process on the side of the plastic sheet, thereby achieving a trimming-free effect.

[0043] Combination Figure 5 As shown, the adsorption shaping member 105 includes a main body 1051 , a suction nozzle 1052 disposed on one side of the main body 1051 , and an air path 1053 disposed on the main body 1051 and in airflow communication with the suction nozzle 1052 .

[0044] When the plastic high temperature sheet is cooled and shaped by the shaping component 10, in order to facilitate the side of the plastic high temperature sheet to be adsorbed and shaped from the feed port 102 to the discharge port 104, in some embodiments, the suction nozzle 1052 can extend along the feed port 102 to the discharge port 104. Or the length of the suction nozzle 1052 can exceed the length of the shaping plate 101 along the feed port 102 to the discharge port 104, so as to increase the adsorption operation area of ​​the suction nozzle 1052 and the plastic high temperature sheet, improve the adsorption capacity and shaping effect, and there is no specific limitation.

[0045] The suction force distribution of the suction nozzle 1052 can be set to be more uniform, so as to uniformly suck and shape the side of the plastic high-temperature sheet. Figure 5 , Figure 6 As shown, the suction nozzle 1052 may include a plurality of suction parts 10521, which are arranged at intervals along a direction from the feed port 102 to the discharge port 104.

[0046] In order to further improve the adsorption capacity of the air suction part 10521, the adsorption contact area between the air suction part 10521 and the plastic sheet is increased. Figure 6 As shown, the air suction portion 10521 can extend in the up-down direction, and the shape of the air suction portion 10521 can be set to be a narrow and long air groove, combined with Figure 7 As shown, the gaps on opposite sides of the shaping channel 103 along the height direction are filled by the suction portion 10521 .

[0047] When arranging multiple air intake sections 10521, in order to facilitate the provision of negative pressure airflow or negative pressure suction force to multiple air intake sections 10521 at the same time, the structure of the air circuit 1053 can be further simplified, so that when the negative pressure airflow or negative pressure suction force of the air circuit 1053 is distributed to multiple air intake sections 10521, the number of channels inside the main body 1051 can be reduced, and a part of the air circuit 1053 can be set inside the main body 1051, and another part of the air circuit 1053 can be set on the surface of the main body 1051.

[0048] Specific, combined Figure 5 As shown, the air circuit 1053 includes a plurality of air inlet channels 10531 disposed inside the main body 1051 and a plurality of air cavities 10532 disposed on the surface of the main body 1051 and connected to the corresponding air inlet channels 10531. Figure 8 As shown, air cavities 10532 are provided on two upper and lower surfaces of the main body 1051, and the air inhalation channel 10531, the two upper and lower air cavities 10532 and the air inhalation part 10521 are sequentially connected with each other by air flow. In this way, one air inhalation channel 10531 can simultaneously supply negative pressure airflow or negative pressure suction force to the air cavities 10532 on the upper and lower surfaces of the main body 1051, and negative pressure airflow or negative pressure suction force is simultaneously supplied to multiple air inhalation parts 10521 through the air cavities 10532.

[0049] In some embodiments, the gas circuit 1053 may also be entirely disposed inside the main body 1051. For example, a main pipe and multiple manifolds may be disposed inside the main body 1051. The main pipe is respectively connected to the multiple manifolds by airflow, and the multiple manifolds are respectively connected to the multiple suction parts 10521. Negative pressure airflow or negative pressure suction force is supplied to the multiple suction parts 10521 through the multiple manifolds inside the main body 1051, without specific limitation.

[0050] Combination Figure 7 , Figure 8 As shown, the suction channel 10531 of the adsorption shaping member 105 can be connected to an external negative pressure air source through a suction air pipe 1054. Such a negative pressure air source can be a negative pressure gas aspirator, a negative pressure air pump, a vacuum compressor, etc., and can be connected to the suction air pipe 1054 through a power part such as a negative pressure air pump, and gas can be sucked from the suction air pipe 1054 with the help of the negative pressure air pump, without specific limitation.

[0051] In summary, the shaping component 10 of the present invention is provided with adsorption shaping parts 105 for adsorbing and shaping the side edges of the plastic sheet on opposite sides of the shaping channel 103. The adsorption shaping parts 105 are configured to be connected to a negative pressure air source. When the high-temperature plastic sheet is cooled and shaped by the improved shaping component 10, the adsorption shaping parts 105 can adsorb and shape the side edges of the high-temperature plastic sheet, thereby avoiding the side edges of the high-temperature plastic sheet from warping, deformation, wrinkles, and other unfavorable conditions, so that the shaped plastic sheet product does not need to go through an additional trimming process, and can achieve the effect of no trimming. Accordingly, the cooling shaping device 100 with the above-mentioned shaping component 10 has a better shaping effect.
