Description

[0002] Foam board is one of the most common foam products. During its production, it requires calendering and shaping. Existing foam board calendering and shaping machines adjust the gap between the upper and lower platens by raising and lowering the upper platen relative to the lower platen to accommodate foam boards of varying thicknesses.

[0003] Currently, the upper platen is typically driven by a pneumatic cylinder or electric push rod. This creates a greater pressure at the point where the upper platen connects to the power structure than at points farther from the structure. This results in uneven force applied to the foam sheet across the entire surface of the upper platen, affecting the uniformity of the foam sheet's thickness. Furthermore, existing calendering machines generally suffer from poor cooling performance. Utility Model Content

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0039] like Figure 1and Figure 2 As shown, this embodiment provides a foam board calendering and shaping machine, comprising:

[0040] Lifting drive member 1;

[0041] The pressing plate includes an upper pressing plate 2 and a lower pressing plate 3. The upper pressing plate 2 is driven by the lifting driving member 1 to rise and fall relative to the lower pressing plate 3. By raising and lowering the upper pressing plate 2 relative to the lower pressing plate 3, the distance between the upper pressing plate 2 and the lower pressing plate 3 is adjusted;

[0042] The auxiliary pressure plate 4 is configured to rise and fall above the upper pressure plate 2. The auxiliary pressure plate 4 is used to assist in applying pressure to the upper pressure plate 2. The auxiliary pressure plate 4 and the lifting drive member 1 apply pressure to different positions of the upper pressure plate 2. Through the cooperation of the auxiliary pressure plate 4 and the lifting drive member 1, the uniformity of the force applied to the entire surface of the upper pressure plate 2 can be improved;

[0043] The cooling liquid circulation mechanism 5 is connected to the pressing plate through a water inlet pipe 6 and a water outlet pipe 7. The cooling liquid circulation mechanism 5 is used to circulate the cooling liquid in the pressing plate;

[0044] The pressing plate is a hollow plate, and a plurality of partitions 8 are provided inside the pressing plate, which divide the inner cavity of the pressing plate into a plurality of cooling chambers.

[0045] A group of water pipes 9 are connected between the water inlet pipe 6 and each cooling cavity. In the traditional solution, there is usually only one large cooling cavity in the pressure plate. After the coolant enters from the water inlet pipe 6, it will flow directly to the water outlet pipe 7. The coolant cannot be evenly distributed in various parts of the cooling cavity, which leads to the limitation of the cooling effect of the pressure plate on the foam plate. In this solution, the coolant is evenly introduced into each cooling cavity through the setting of multiple components of water pipes 9 and multiple cooling cavities, thereby ensuring the cooling effect of the pressure plate on the foam plate.

[0046] It should be noted that, in this embodiment, the lifting drive member 1 can be a cylinder or an electric push rod, and the lifting drive member 1 is a prior art.

[0047] Specifically, see Figure 1 In this embodiment, the lifting drive member 1 is connected to the center position of the upper pressure plate 2, and the auxiliary pressure plate 4 is a U-shaped structure. The lifting drive member 1 passes through the middle of the auxiliary pressure plate 4 and is connected to the upper pressure plate 2. When the upper pressure plate 2 cooperates with the lower pressure plate 3 to calender and shape the foam board, the lifting drive member 1 applies force to the middle part of the upper pressure plate 2, and the auxiliary pressure plate 4 applies force to the edge of the upper pressure plate 2, thereby ensuring the uniformity of force on the entire surface of the upper pressure plate 2, that is, improving the uniformity of pressure applied by the upper pressure plate 2 on the foam board.

[0048] Specifically, see Figure 1 and Figure 3In this embodiment, a foam board calendering and shaping machine further includes a support frame 10, a set of drive components are connected to the four corners of the auxiliary pressure plate 4, and the lifting drive member 1 and the drive component are both arranged on the support frame 10;

[0049] The support frame 10 is also provided with a power mechanism, and the driving assembly is connected to the power mechanism. The four groups of driving assemblies are driven to move synchronously by the power mechanism. Under the action of the power mechanism, the four groups of driving assemblies are driven to rise and fall synchronously, thereby ensuring that the auxiliary pressure plate 4 is stably lifted and lowered relative to the upper pressure plate 2.

[0050] During use, the auxiliary pressure plate 4 is driven to rise and fall above the upper pressure plate 2 through the synchronous action of the four groups of drive components. When the auxiliary pressure plate 4 is driven to be pressed on the upper pressure plate 2, the auxiliary pressure plate 4 cooperates with the lifting drive 1 to apply uniform pressure to the entire surface of the upper pressure plate 2; and the setting of the four groups of drive components can improve the overall force uniformity of the auxiliary pressure plate 4, thereby ensuring the uniformity of the force applied by the auxiliary force plate to the pressure plate.

[0051] It should be noted that in order to ensure that the upper pressure plate 2 can be lifted and lowered stably vertically, the upper pressure plate 2 is also connected to a guide mechanism that can ensure that the upper pressure plate 2 can be lifted and lowered stably vertically. For example, the guide mechanism in this embodiment includes a guide sleeve and a guide slide rod. The guide sleeve is fixed on the support frame 10, and the guide slide rod is slidably arranged in the guide sleeve and is connected to the upper pressure plate 2.

[0052] Specifically, see Figure 3 In this embodiment, the power mechanism includes:

[0053] The power motor 11 is fixedly mounted on the support frame 10;

[0054] The transmission shaft 12 is rotatably mounted on the support frame 10, and a set of first driving bevel gears 13 are fixedly mounted on both ends of the transmission shaft 12;

[0055] Two sets of drive shafts 14 are rotatably mounted on the support frame 10. The two sets of drive shafts 14 correspond to the two ends of the transmission shaft 12. A set of first driven bevel gears 15 is fixed to the middle of the drive shaft 14, and a set of second active bevel gears 16 are fixed to the two ends of the drive shaft 14.

[0056] Among them, a set of belt pulleys are fixed on the output shaft of the power motor 11 and the transmission shaft 12, and a driving belt 17 is sleeved on the belt pulley. Under the action of the driving belt 17, the power motor 11 can drive the transmission shaft 12 to rotate;

[0057] The first driven bevel gear 15 is meshed with the first driving bevel gear 13 . Through the meshing transmission between the first driving bevel gear 13 and the first driven bevel gear 15 , the transmission shaft 12 drives the two sets of drive shafts 14 to rotate synchronously.

[0058] It is worth noting that, in this embodiment, the two sets of drive shafts 14 rotate in opposite directions.

[0059] Specifically, see Figure 3 In this embodiment, the driving component includes:

[0060] The nut cylinder 18 is rotatably mounted on the support frame 10 , and a second driven bevel gear 19 is fixedly mounted on the nut cylinder 18 ;

[0061] The threaded rod 20 is connected to the nut barrel 18 through a thread, and the auxiliary pressure plate 4 is connected to the threaded rod 20;

[0062] Among them, the second driven bevel gear 19 is engaged with the second active bevel gear 16. Under the meshing transmission action of the second active bevel gear 16 and the second driven bevel gear 19, the driving gear drives the nut cylinder 18 to rotate, and the nut cylinder 18 can drive the threaded rod 20 to drive the auxiliary pressure plate 4 to rise and fall.

[0063] It is worth noting that in this embodiment, the two groups of threaded barrels corresponding to the two ends of a set of drive shafts 14 have opposite directions, which can be specifically set by the thread direction of the nut barrel 18 and the threaded rod 20. When the power motor 11 is working, the four groups of threaded rods 20 are driven to rise and fall synchronously.

[0064] Specifically, see Figure 1 In this embodiment, the cooling liquid circulation mechanism 5 includes:

[0065] Water tank 21, the water outlet pipe 7 is connected to the water tank 21,

[0066] The water pump 22 has its water inlet connected to the water tank 21 through a pipe, and its water outlet connected to the water inlet pipe 6. The water pump 22 circulates the coolant between the water tank 21 and the cooling cavity in the pressure plate.

[0067] It is worth noting that a refrigerator and a temperature sensor are provided in the water tank 21 , and the water tank 21 provided with a refrigerator and a temperature sensor is prior art.

[0068] The present embodiment provides a foam board calendering and shaping machine, wherein multiple foam board calendering and shaping machines can be connected in series when in use. The working principle thereof is as follows:

[0069] (1) The foamed sheet is guided out from the discharge port of the extruder and enters between the upper pressing plate 2 and the lower pressing plate 3. The upper pressing plate 2 is driven downward by the lifting drive 1 so that the gap between the upper pressing plate 2 and the lower pressing plate 3 can adapt to the thickness of the foamed sheet. The foamed sheet is continuously passed through between the upper pressing plate 2 and the lower pressing plate 3 by the traction machine.

[0070] (2) Start the power motor 11 to rotate forward. Under the action of the drive belt 17, the power motor 11 drives the transmission shaft 12 to rotate. The transmission shaft 12 drives the first active bevel gear 13 to rotate. Under the meshing action of the first active bevel gear 13 and the first driven bevel gear 15, the two sets of drive shafts 14 at both ends are driven to rotate in opposite directions. The drive shaft 14 drives the second active bevel gear 16 to rotate. Under the action of the second active bevel gear 16 and the second driven bevel gear 19, the nut barrels 18 at both ends are driven to rotate in the opposite direction.

[0071] By adjusting the thread directions of the four sets of nut barrels 18 and the threaded rods 20, the four sets of nut barrels 18 drive the four sets of threaded rods 20 to descend synchronously, and the four sets of threaded rods 20 drive the auxiliary pressure plate 4 in the shape of a square to descend steadily. The auxiliary pressure plate 4 is pressed on the upper pressure plate 2 and applies force to the four sides of the upper pressure plate 2;

[0072] The cooperation of the U-shaped auxiliary pressure plate 4 and the lifting drive member 1 improves the uniformity of the force applied on the entire surface of the upper pressure plate 2, thereby ensuring the uniformity of the pressure applied by the upper pressure plate 2 on the foaming plate and the uniformity of the thickness of the foaming plate.

[0073] (3) While the foaming board is being calendered and shaped, the cooling liquid is circulated between the water tank 21 and the cooling cavity of the pressing plate under the action of the water pump 22, and the cooling liquid can be evenly dispersed in the pressing plate by setting up multiple cooling cavities and multiple water distribution pipes 9, thereby ensuring the cooling effect of the pressing plate on the foaming board.

[0074] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
