Description

Technical Field

[0002] Foam products, due to their lightweight and easy-to-process characteristics, are widely used in clothing displays, footwear manufacturing, and advertising decoration. These products include, but are not limited to, mannequins, shoe lasts, and sculptures, all of which require precise dimensional control and a smooth surface finish.

[0038] like Figures 1 to 8 As shown, this utility model relates to a carving and molding device for foam products, comprising a cabinet 10, a carving mechanism 20, a pressing mechanism 30, and a rotating mechanism 40. In use, the foam product is fixed above the rotating mechanism 40, and the pressing mechanism 30 presses the foam product downwards; the rotating mechanism 40 drives the foam product to rotate, coordinating with the multi-axis motion of the carving mechanism 20 to carve and shape the foam product.

[0039] Please see Figures 1 to 4 The cabinet 10 serves as the main supporting structure, employing a closed design combining a rigid frame and a panel. The cabinet 10 has a first inner sidewall 11 and a second inner sidewall 12 arranged in parallel opposite directions, used to fix the engraving mechanism 20 and the clamping mechanism 30, respectively. A discharge port 13 is provided on the side of the cabinet 10, and a diagonally arranged guide plate 14 is provided at the bottom of the cabinet 10. The lower end of the guide plate 14 extends to the discharge port 13. The discharge port 13 and the diagonally installed guide plate 14 together constitute a waste discharge system. In practical applications, the discharge port 13 is connected to a negative pressure device to effectively discharge waste generated during engraving and forming from within the cabinet 10. The cabinet 10 has hinged double doors 15 at both the front and rear, each with an observation window 16 positioned directly opposite the processing area for observation.

[0040] Please see Figure 5 and Figure 6The engraving mechanism 20 is fixedly installed on the first inner wall 11 of the cabinet 10. It is composed of the Z-axis drive module 21, the Y-axis drive module 22, the X-axis drive module 23 and the engraving execution module 24 connected in sequence to realize precise positioning and engraving operations in three-dimensional space.

[0041] Specifically, the Z-axis drive module 21 adopts a dual-motor synchronous drive structure, including a lifting seat 211 and two lifting motors 212 symmetrically arranged on both sides of it. The output shaft of the lifting motors 212 is equipped with a first transmission gear 213. The first inner sidewall 11 of the cabinet 10 has two vertical guide rails 214 symmetrically arranged on both sides of the lifting seat 211, and two vertical racks 215 symmetrically arranged on both sides of the lifting seat 211. The first transmission gear 213 meshes with the vertical racks 215, and the lifting seat 211 is slidably connected to the vertical guide rails 214 on the cabinet 10 via a slider. The two lifting motors 212, through the meshing of the first transmission gear 213 and the vertical racks 215, synchronously drive the lifting seat 211 to move up and down along the vertical guide rails 214 in the Z-axis direction, ensuring smooth movement and precise positioning.

[0042] Specifically, the Y-axis drive module 22 is mounted on the lifting base 211, including a movable base 221 and a transverse motor 222 fixed to the top of the movable base 221. The output shaft of the transverse motor 222 is equipped with a second transmission gear 223. A transverse rack 224 is provided on the rear side of the lifting base 211, and a transverse guide rail 225 is provided at the bottom of the lifting base 211. The second transmission gear 223 meshes with the transverse rack 224; the movable base 221 is slidably connected to the transverse guide rail 225 at the bottom of the lifting base 211 via a slider. The transverse motor 222 drives the movable base 221 to move horizontally along the transverse guide rail 225 in the Y-axis direction through the meshing of the second transmission gear 223 and the transverse rack 224.

[0043] Specifically, the X-axis drive module 23 is mounted on the movable base 221 and includes a feed guide rail 231, a feed motor 232, and a sliding base 233. The feed motor 232 is mounted on one end of the feed guide rail 231 and connected to the sliding base 233; the sliding base 233 is slidably engaged with the feed guide rail 231. The feed motor 232 drives the sliding base 233 to move linearly along the feed guide rail 231 in the X-axis direction; the feed mechanism and the sliding base 233 adopt a screw 311 transmission structure. The engraving execution module 24 is fixedly mounted on the sliding base 233 to realize the final engraving operation.

[0044] Specifically, the engraving execution module 24 consists of an engraving motor 241 and an engraving head 242. The engraving motor 241 is fixed on the sliding base 233, and its output shaft is directly connected to the engraving head 242 through a coupling.

[0045] Please see Figure 7The clamping mechanism 30 is fixedly installed on the second inner wall 12 of the cabinet 10, opposite to the engraving mechanism 20, and is used to stably fix the foam product during processing. The clamping mechanism 30 mainly includes a clamping lifting module 31 and a downward pressing component 32 mounted on it, achieving precise pressure control through mechanical linkage. The clamping mechanism 30 works in conjunction with the rotating mechanism 40 to provide a stable clamping force during processing. When the rotating mechanism 40 drives the workpiece to rotate, the clamping mechanism 30 can always maintain a constant downward pressure, effectively preventing workpiece displacement or vibration and ensuring engraving accuracy.

[0046] Specifically, the pressing and lifting module 31 adopts a twin-screw 311 synchronous drive structure, including two vertically arranged screws 311, a movable component 312 threadedly engaged with the screws 311, a drive motor 313, and a transmission belt 316. A first transmission wheel 314 is mounted on the top of each screw 311, and a second transmission wheel 315 is provided on the output shaft of the drive motor 313. The first transmission wheel 314 and the second transmission wheel 315 are connected by the transmission belt 316. When the drive motor 313 operates, it drives the two screws 311 to rotate synchronously via belt drive, causing the movable component 312 to perform precise lifting and lowering movements along the axis of the screws 311. This twin-screw 311 synchronous drive design effectively avoids the skew problem that may occur with single-sided drive, ensuring uniform distribution of downward pressure.

[0047] Please see Figure 8 The rotating mechanism 40 is located at the bottom of the cabinet 10 and includes a rotating drive module 41 and a rotating platform 42. Through cooperation with the pressing mechanism 30, it provides stable rotational support for the foam products.

[0048] Specifically, the rotary drive module 41 uses a high-torque servo motor as its power source and is connected to the rotary platform 42 via a precision reducer. The rotary platform 42 is equipped with a workpiece clamping structure, which includes multiple clamping blocks 43 arranged in a circumferential array. Each clamping block 43 consists of a connecting base plate 431 and an abutment plate 432, which are arranged vertically and reinforced by reinforcing ribs 433. The connecting base plate 431 has positioning holes, and correspondingly, the rotary platform 42 has locking holes 421. The positioning holes mate with the locking holes 421 on the rotary platform 42, allowing for quick installation and position adjustment of the clamping blocks 43 via fasteners. This modular design enables the clamping structure to adapt to foam products of different sizes and shapes.

[0049] Compared to existing technologies, the engraving and molding equipment for foam products involved in this utility model achieves high-precision and high-efficiency processing of foam products. Through the coordinated operation of the clamping mechanism 30 and the rotating mechanism 40, the clamping mechanism 30 adopts twin-screw 311 synchronous drive technology, and ensures synchronous downward pressure on both sides through belt transmission. Combined with the multi-position adjustable clamping device on the rotating platform 42, a stable three-dimensional clamping system is formed, effectively preventing displacement or deformation of the foam product during processing. The engraving mechanism 20 adopts an XYZ three-axis precision drive module, with each axis using high-rigidity guide rails and precision transmission mechanisms. Combined with the rotating platform 42, which can rotate continuously 360 degrees, it constitutes a complete multi-degree-of-freedom processing system. Through multi-axis linkage control algorithms, it can accurately realize the engraving path of complex curved surfaces in space and complete the continuous processing of various surfaces of the foam product.

[0050] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
