Detailed Description
Referring to fig. 1 and 6, the present invention provides a foaming device, which comprises a foaming box 4, a cylindrical sealing box and a rotating device 3, wherein the sealing box is installed on the rotating device 3, and the foaming box 4 is arranged in the sealing box.
The foaming liquid foams in the foaming tank 4, and naturally, air in the sealed tank (and in the foaming tank 4) is pumped away in the foaming process, so that the air pressure is reduced, and the foaming rate is increased.
The utility model discloses mainly solve 2 problems: 1. the problem that the top of the foaming material is uneven is solved; 2. solves the problem of uneven density of the foaming material.
Regarding the problem of uneven top of the foam:
referring to fig. 2 and 4, a layer of release film (function: facilitating the release of the foamed material at the later stage) is required to be laid in the normal foaming box 4.
The utility model discloses on the basis of the drawing of patterns film that remains original foaming case 4 bottom and lay, increase in addition and can reciprocate carry limit film 6, should carry limit film 6 and be annular, cooperate (laminate) with the inner wall of foaming case 4, but should carry the height of highly < foaming case 4 of limit film 6.
In brief, the edge-lifting film 6 can be moved upward under manual control (to the highest height, the upper side of the edge-lifting film 6 is flush with the opening of the foaming tank 4). Initially, the edge lifting film 6 is located at the lowest side of the foaming box 4 (the edge lifting film 6 is entirely in an unfolded state, and the lower side of the edge lifting film 6 is flush with the lower side of the foaming box 4, or the upper side of the edge lifting film 6 is lower than the box opening of the foaming box 4), when foaming liquid is foamed, the middle of the foaming liquid is lifted faster and the periphery is lifted slower due to higher viscosity of the foaming liquid, when the peripheral foaming liquid rises to the upper side of the edge lifting film 6, the edge lifting film 6 is lifted upwards, and since the foaming liquid is adhered to the edge lifting film 6 at this time, the height of the peripheral foaming liquid is artificially lifted, so that the height of the peripheral foaming liquid is equal to the height of the middle foaming liquid, then the foaming liquid continues to foam, and the low-lying part between the peripheral foaming liquid and the middle foaming liquid is filled, so that the upper side of the obtained foamed object is flush, the utilization rate of the foaming material is improved.
In order to realize the purpose of automatically lifting the edge film 6, the utility model adopts the following technical scheme:
an annular sealing plate 5 is arranged on the upper side of the edge lifting film 6, the outer side of the annular sealing plate 5 is matched with the inner side surface of the foaming box 4, and the annular sealing plate 5 can slide along the foaming box 4.
In addition, the whole sealing box is composed of two parts, namely an upper cover 1 and a lower cover 2, the foaming box 4 is integrally fixed in the lower cover 2, the box opening of the foaming box 4 faces the direction of the upper cover 1, a lifting device 9 (an air cylinder or an oil cylinder) is installed on the upper cover 1, and the lifting end of the lifting device 9 is connected with the annular sealing plate 5.
In short, when the edge lifting film 6 needs to be lifted upwards, the lifting device 9 works to pull the annular sealing plate 5 to move upwards, and the edge lifting film 6 can be driven to move upwards because the edge lifting film 6 is fixedly connected with the annular sealing plate 5.
And the annular sealing plate 5 is provided here in the sense that: the edge lifting film 6 can be better connected with the edge lifting film 6 at the position, the edge lifting film 6 is convenient to lift (the stress of the edge lifting film 6 is more uniform in the process of lifting the edge lifting film 6), and if the edge lifting film 6 is directly connected with the lifting device 9, the tearing of the edge lifting film 6 is probably caused because the force applied by the lifting device 9 is a point in the lifting process.
Moreover, the foaming box 4 is further provided with a cover plate 7, and the main purpose of the cover plate 7 is to enable the whole foaming box 4 to be turned upside down when the rotating device 3 (the latter part is related to) works, and the cover plate 7 can hold the foaming liquid flowing downwards after being turned upside down and prevent the foaming liquid from entering the outer side of the foaming box 4; and to ensure that the upper surface of the foam is perfectly level (further improving the flatness of the upper surface of the foam).
In order to achieve the above purpose, the cover plate 7 should be sized to fit the opening (tank opening) of the foaming tank 4, or the cover plate 7 should be sized to fit the inside of the ring seal plate 5 (the tank opening of the foaming tank 4 is integrally sealed by the ring seal plate 5 and the cover plate 7).
However, the inventors considered that the entire foaming tank 4 was sealed after adding the lid plate 7, and thus it was impossible to inject the foaming liquid into the foaming tank 4.
To solve this problem, the inventors made the following improvements:
firstly, the cover plate 7 is movable (can move up and down), and after the cover plate 7 moves upwards, the box opening of the foaming box 4 is opened, so that foaming liquid can be injected into the foaming box 4; after the foaming liquid is injected, the cover plate 7 moves downwards, so that the cover plate 7 is matched with the annular sealing plate 5 to seal the box opening of the foaming box 4, and the cover plate 7 also moves upwards along with the annular sealing plate 5 in the process of lifting the annular sealing plate 5 upwards.
Furthermore, since the space in the sealing box is relatively limited, it is not possible to provide a lifting device 9 for the cover plate 7 in a specific manner from the viewpoint of cost saving and from the practical point of view.
It is thus necessary to be able to lift or lower the cover plate 2 alone and to lift the cover plate 7 and the annular sealing plate 5 simultaneously, solely by means of the lifting device 9, using only the existing lifting device 9.
The adopted specific technical scheme is as follows:
referring to fig. 3, first, the cover plate 7 is fitted to the inner side of the annular sealing plate 5, the rigid frame 8 is disposed on the cover plate 7, the rigid frame 8 is fixedly connected to the cover plate 7, pneumatic connecting pins 81 are disposed on both sides of the rigid frame 8, the annular sealing plate 5 is provided with a vertical guide body 52, and the guide body 52 is provided with a connecting hole 53.
Referring to fig. 5, the lifting device 9 is directly connected to the rigid frame 8, the lifting device 9 is not directly connected to the annular sealing plate 5, when the annular sealing plate 5 needs to be lifted, the cover plate 7 is put down by the lifting device 9 at this time, so that the cover plate 7 is just matched with the annular sealing plate 5, the pneumatic connecting bolt 81 starts to work, so that the bolt extends out (extends out of the outer side of the cover plate 7, at an overlooking angle, a projection part of the bolt is on the outer side of the cover plate 7), at this time, the bolt is just inserted into the connecting hole 53 of the guide body 52, so that the cover plate 7 and the annular sealing plate 5 are connected into a whole, the cover plate 7 is lifted upwards at this time, and the whole annular sealing plate 5 can.
Of course, to achieve the above purpose, the rigid frame 8 can be eliminated and the pneumatic connecting pins 81 can be provided directly on the cover plate 7.
The number of the rigid frames 8 is 2, two ends of each rigid frame 8 are respectively provided with a pneumatic connecting bolt 81, the two rigid frames 8 are oppositely arranged in the length direction of the cover plate 7, the width of each rigid frame 8 is equal to the width of the annular sealing plate 5 (the width of each rigid frame 8 refers to the length in the width direction of the cover plate 7), therefore, when the cover plate 7 is matched with the annular sealing plate 5, the rigid frames 8 are directly erected on the annular sealing plate 5, and two ends of each rigid frame 8 are provided with transition holes matched with the guide bodies 52.
When the rigid frame 8 is mounted on the annular sealing plate 5, the guide body 52 is inserted through the transition hole, and the pneumatic connecting pin 81 is operated so that the pin is inserted into the connecting hole 53.
The size at the top end of the guide body 52 is small, when the cover plate 7 moves downwards, the guide body 52 can easily enter the transition hole, the position of the cover plate 7 is adjusted in a self-adaptive mode through 4 guide bodies 52, and the pneumatic connecting bolt 81 can be smoothly inserted into the connecting hole 53 in the later period.
Specifically, when the foaming liquid is foamed, the cover plate is moved to a position flush with the upper side of the edge lifting film 6 under the action of the lifting device, the cover plate is positioned in the foaming box at the moment, so that the space where the foaming liquid can be foamed is relatively limited (the part below the cover plate), because the foaming space is small, the middle part of the foaming liquid is firstly contacted with the cover plate when the foaming liquid is foamed, the foaming liquid cannot be foamed upwards continuously due to the obstruction of the cover plate and can only be foamed to the peripheral low-lying positions quickly, so that the foaming liquid is filled in the foaming space below the whole cover plate, because the foaming liquid is continuously foamed, the foaming liquid applies an upward force to the cover plate, after the force reaches a certain degree, the cover plate and the edge lifting film are lifted upwards simultaneously through the lifting device (at the moment, the foamed object on the upper side is already in a semi-cured state), and the edge lifting film can integrally drive the semi-cured foamed object on the upper, because the semi-cured foaming material on the upper side is not pressed and the whole foaming space is enlarged, the foaming liquid on the lower side can be more fully foamed, so that the density of the finally obtained foaming material is more uniform.
In addition, it should be emphasized that, when the cover plate and the edge-lifting film are lifted upwards, the foaming space becomes large, the upper foaming substance is semi-solidified, the semi-solidified foaming substance moves upwards along with the semi-solidified foaming substance, the foaming liquid is in a viscous state, and the foaming liquid is pulled to form a gel to fill the whole enlarged foaming space, so as to ensure the uniformity of the density of the foaming substance.
The edge-lifting film has the main function of driving the semi-cured foam upwards.
The cover plate 7 is also provided with a sensor for detecting the pressure on the cover plate, and the sensor is used for judging when the cover plate and the edge lifting film are lifted upwards (the foaming material on the upper side is semi-solidified) according to the detected pressure.
The sensor in the figure is of course mounted on a connection plate 10, which connection plate 10 is located between the cover plate 7 and the rigid frame 8.
Referring to fig. 4, furthermore, since ring seal plate 5 is not directly connected to lifting device 9, and thus the entire membrane 6 and ring seal plate 5 may fall into foaming tank 4 when membrane 6 and ring seal plate 5 are mated with foaming tank 4, a plurality of straps 51 are provided on ring seal plate 5, and the ring seal ring may be suspended from the rim of foaming tank 4 by these straps 51, and straps 51 are of such a length that membrane 6 is in the lowermost position within foaming tank 4.
Regarding the problem of uneven density of the foam:
mainly by providing the rotating means 3,
after foaming liquid is injected into the foaming box, the foaming box can be rotated left and right (45 degrees inclined to the left and 45 degrees inclined to the right) through the rotation of the rotating device, so that the foaming liquid flows to the two sides of the box bottom of the foaming box rapidly, the foaming liquid rises uniformly in height during foaming, the flatness of the upper surface of a foaming object is improved, the acting time of the foaming object for jacking (contacting with a cover plate) is shortened, meanwhile, the foaming liquid is adhered to the side surface of the foaming box, the upward rising resistance of the foaming liquid is reduced, and the overall density of the foaming object is more uniform.
As for the specific structure of the rotating device 3, there are many options in practical applications, and the application is not limited herein, and the purpose thereof is only to drive the seal box to rotate.
Other settings are as follows:
the seal box includes upper cover 1 and lower cover 2, through hinged joint between upper cover 1 and the lower cover 2, be equipped with annular sealing strip between upper cover 1 and the lower cover 2, the length direction both sides of lower cover 2 are fixed with one device 11 of uncapping respectively, device 11 of uncapping adopts cylinder or hydro-cylinder, the cylinder body of device 11 of uncapping articulates on the lower cover 2, the free end of the body of rod of device 11 of uncapping with upper cover 1 is articulated.
The hermetic container can be relatively easily opened and closed by providing the lid opening device 11.
The height of the edge lifting film 6 is 1/3-2/3 of the height of the foaming box 4, and a demoulding film is laid at the bottom of the foaming box 4. Taking the height of the normal edge lifting film 6 as 1/2 of the height of the foam box 4 as an example, in this case, the release film at the bottom of the foam box 4 covers at least the height of the lower side 1/2 of the inner side wall of the foam box 4 so as to ensure that the entire foamed object is in the film (fixing the release film and the edge lifting film 6) when the edge lifting film 6 is lifted to the uppermost side (the upper edge of the edge lifting film 6 is flush with the box opening of the foam box 4), and the release film is provided on the lower side of the cover plate 7.
The working method for producing the foaming material by using the utility model comprises the following steps:
1. opening the upper cover 1, and injecting foaming liquid into the foaming box 4;
2. closing the upper cover 1, starting to vacuumize the sealed box, and starting foaming the foaming liquid;
3. in the process of the second step, the sealing box can be rotated 45 degrees leftwards by the rotating device 3, so that the foaming liquid flows to the left side edge of the edge lifting film 6 and the two ends of the left side bottom, after a period of time (the specific time is actually set), the whole sealing box is rotated 90 degrees rightwards (the whole sealing box is deviated 45 degrees rightwards), so that the foaming liquid flows to the two ends of the right side bottom and the right side bottom of the edge lifting film, the sealing box stops for a period of time, and the sealing box rotates to the initial position to foam;
4. the cover plate 7 is pressed downwards to be matched with the annular sealing plate 5, and when the sensor detects that the pressure value reaches a specified value, the annular sealing plate 5 and the film 6 are integrally driven to move upwards until the upper edge of the edge lifting film 6 is flush with the box opening of the foaming box 4;
