Description

Technical Field

[0001] This invention relates to the field of sponge cutting technology, and in particular to a sponge shaping and cutting device and its cutting process. Background Technology

[0002] Sponge shaping and cutting equipment is an automated machine used to precisely cut soft materials such as sponges and foams, aiming to efficiently process block raw materials into finished products of predetermined shapes and sizes.

[0003] Its core technologies include laser cutting, electrothermal wire melting, and high-speed blade mechanical cutting. Advanced equipment also integrates a three-dimensional contour cutting system, which can complete three-dimensional modeling in one go. This type of equipment is widely used in furniture manufacturing, automotive interiors, packaging padding, and medical devices, and is a key piece of equipment for realizing the large-scale and customized production of sponge products.

[0004] Generally, to form a curved sponge in one go, a mold is used to squeeze the square-shaped sponge material, causing the square sponge to deform to different degrees in different parts. Then, a tensioned electric heating wire is used to pass through the deformed sponge. After the mold releases the pressure, the sponge returns to its free state, and the sponge shape is formed in one go. However, the existing sponge cutting molds are expensive and the cutting equipment has a short lifespan. Summary of the Invention

[0005] To overcome the technical defects of existing technologies, this invention provides a sponge shaping and cutting device and its cutting process, which has a long service life.

[0006] The technical solution adopted in this invention is: A sponge shaping and cutting device includes an upper pressing system, a lower mold system, a lateral movement power system, a sliding frame, a cutting system, and a mold pressing power device. The sliding frame is slidably mounted on the upper side of the lateral movement power system. The upper pressing system is slidably mounted on the sliding frame. The lower mold system is mounted on the sliding frame. The mold pressing power device is mounted on the lower mold system and is drive-connected to the upper pressing system. The lateral movement power system is drive-connected to the sliding frame. The upper pressing system and the lower mold system are arranged opposite to each other. The cutting system includes a fixed rod, a cutting rope, a vibrating rod, and a vibration clutch device. The lower mold system has a cutting slit through which the cutting rope passes. The fixed rod and the vibrating rod are located on both sides of the lower mold system. The vibration clutch device includes an elastic mounting plate, a vibration clutch block, and a vibration motor. The vibration motor is mounted on the top of the vibration rod. The vibration clutch block is mounted on the vibration rod through the elastic mounting plate. The two ends of the cutting rope are mounted on the fixed rod and the vibration clutch block, respectively. An elastic plate is also mounted on the top of the fixed rod. The cutting rope is mounted on the elastic plate. The output end of the vibration motor passes through the vibration clutch block. There is a gap between the vibration clutch block and the output end of the vibration motor.

[0007] Preferably, the pressing system includes a pressing sliding plate and a plurality of guide sleeves, each of the guide sleeves being mounted on the pressing sliding plate, and the pressing sliding plate being slidably mounted on the sliding frame in the lifting direction via the guide sleeves.

[0008] Preferably, the lower mold system includes a lower template and several forming cylinders. A silicone sheet is installed on the top of the output end of each forming cylinder. The forming cylinders are continuously distributed on the lower template in four directions. The lower template is installed on a sliding frame. The cutting seam is located on the lower template.

[0009] Preferably, the lateral movement power system includes a lateral movement power motor, a lateral movement lead screw, and a lateral movement slider. The lateral movement slider is installed at the bottom of the sliding frame, the lateral movement lead screw is connected to the sliding frame via a threaded pair, and the lateral movement lead screw is installed at the output end of the lateral movement power motor.

[0010] Preferably, the sliding frame includes a sliding base and a plurality of guide columns, the guide columns being arranged parallel to each other on the sliding base, the sliding base being connected to the transverse motion system, the upper pressing system being slidably mounted on the sliding frame in the lifting direction, and the lower mold system being mounted on the guide columns.

[0011] Preferably, the mold pressing power device is a pressing power cylinder.

[0012] Preferably, the gap between the output end of the vibration motor and the vibration clutch is 0.5 mm to 1 mm.

[0013] The cutting process of sponge shaping and cutting equipment includes the following steps: S1: The sponge is placed on the lower mold system, and the upper pressing system descends under the drive of the mold pressing power device, pressing the sponge onto the lower mold system; S2: The lateral movement system drives the sliding frame to slide, causing the sponge and the cutting rope to slide against each other; S3: After the cutting rope is subjected to force, it pulls the vibration clutch block, and the elastic mounting plate deforms, which in turn makes the traction vibration clutch block contact the output end of the vibration motor and thus transmit vibration. S4: After cutting is completed, the cutting rope is no longer under force, and the elastic mounting plate drives the vibration clutch block to disengage from the output end of the vibration motor.

[0014] The beneficial effects of this invention are: The sliding frame is slidably mounted on the upper side of the lateral movement power system, driving the sponge to move laterally, causing relative movement between the block sponge and the cutting system. The upper pressure system is slidably mounted on the sliding frame. The cutting system passes through the pre-set cutting slit of the lower mold system, and cuts as it moves along the cutting slit. The lower mold system is mounted on the sliding frame, and the mold pressing power device is mounted on the lower mold system. The mold pressing power device is connected to the upper pressure system. The lateral movement power system is connected to the sliding frame. The lateral movement power system drives the sliding frame to move laterally, and the cutting system moves laterally along with the sliding frame, causing relative movement between the block sponge and the cutting system. The upper pressure system and the lower mold system are set opposite each other to clamp the sponge, causing the sponge to deform in accordance with the lower mold system. The degree of deformation of the sponge varies in different parts under the clamping of the upper pressure system and the lower mold system. Due to the different degrees of deformation inside the block sponge when the cutting system moves laterally, the sponge produces a curved outer contour after passing through the cutting system.

[0015] The cutting system includes a fixed rod, a cutting rope, a vibrating rod, and a vibration clutch device. The lower die system has a cutting slit for the cutting rope to pass through. The fixed rod and vibrating rod are located on opposite sides of the lower die system. The vibration clutch device includes an elastic mounting plate, a vibration clutch block, and a vibration motor. The elastic mounting plate prevents the cutting rope from being damaged by excessive tension. The vibration motor is mounted on the top of the vibrating rod, and the vibration clutch block is mounted on the vibrating rod via the elastic mounting plate. Both ends of the cutting rope are mounted on the fixed rod and the vibration clutch block, respectively. An elastic plate is also mounted on the top of the fixed rod, and the cutting rope is mounted on the elastic plate. This ensures that both ends of the cutting rope vibrate during operation. The design provides space for the cutting rope to vibrate, increasing friction between the rope and the sponge during cutting. This creates a continuous reciprocating cutting effect, increasing the cutting speed. The output end of the vibration motor passes through a vibration clutch block, with a gap between them. When the cutting rope is under stress, it drives the vibration clutch block to overcome the elastic force of the elastic mounting plate, connecting the clutch block to the motor's output end and causing the cutting rope to vibrate. After cutting, the clutch block disengages from the motor's output end, reducing vibration and preventing damage from continuous vibration-induced tension changes, thus extending the rope's service life.

[0023] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 6 As shown, this embodiment provides a sponge shaping and cutting device, including an upper pressing system 1, a lower mold system 2, a lateral movement force system 3, a sliding frame 4, a cutting system 5, and a mold pressing power device 6. The sliding frame 4 is slidably mounted on the upper side of the lateral movement force system 3, driving the sponge to move laterally, causing relative movement between the block sponge and the cutting system 5. The upper pressing system 1 is slidably mounted on the sliding frame 4, and the lower mold system 2 is mounted on the sliding frame 4. The cutting system 5 passes through a pre-set cutting slit 22 in the lower mold system 2, and cuts as it moves along the cutting slit 22. The mold pressing power device 6 is mounted on the lower mold system 2, and the mold... The downward pressing power device 6 is connected to the upper pressing system 1 through a transmission, and the lateral moving power system 3 is connected to the sliding frame 4 through a transmission. The lateral moving power system 3 drives the sliding frame 4 to move laterally, and the cutting system 5 moves laterally along with the sliding frame 4, so that the block sponge and the cutting system 5 move relative to each other. The upper pressing system 1 and the lower mold system 2 are set opposite to each other to clamp the sponge, so that the sponge conforms to the lower mold system 2 and deforms. The degree of deformation of the sponge is different in different parts under the clamping of the upper pressing system 1 and the lower mold system 2. When the block sponge moves laterally, due to the different degree of deformation inside the block sponge, the sponge produces a curved outer contour after passing through the cutting system 5.

[0024] The cutting system 5 includes a fixed rod 51, a cutting rope 52, a vibrating rod 53, and a vibration clutch device 55. The lower mold system 2 has a cutting slit 22 through which the cutting rope 52 passes. The fixed rod 51 and the vibrating rod 53 are located on opposite sides of the lower mold system 2. The vibration clutch device 55 includes an elastic mounting plate 551, a vibration clutch block 552, and a vibration motor 553. The elastic mounting plate 551 prevents the cutting rope 52 from being damaged due to excessive tension. The vibration motor 553 is mounted on the top of the vibrating rod 53. The vibration clutch block 552 is mounted on the vibrating rod 53 via the elastic mounting plate 551. Both ends of the cutting rope 52 are mounted on the fixed rod 51 and the vibration clutch block 552, respectively. An elastic plate is also mounted on the top of the fixed rod 51, and the cutting rope 52 is mounted on the elastic plate. Thus, when the cutting rope 52 vibrates, both ends of the cutting rope 52 are... The system provides space for the vibration of the cutting rope 52. During cutting, the vibration of the cutting rope 52 increases the friction between the cutting rope 52 and the sponge, generating a continuous reciprocating cutting effect and increasing the cutting speed. The output end of the vibration motor 553 passes through the vibration clutch block 552, and there is a gap between the vibration clutch block 552 and the output end of the vibration motor 553. After the cutting rope 52 is subjected to force, the cutting rope 52 drives the vibration clutch block 552 to overcome the elastic force of the elastic mounting plate 551, so that the vibration clutch block 552 is connected to the output end of the vibration motor 553, causing the cutting rope 52 to vibrate. After the cutting is completed, the vibration clutch block 552 disengages from the output end of the vibration motor 553, reducing the vibration of the cutting rope 52 and preventing damage to the cutting rope 52 due to the tension changes caused by continuous vibration, resulting in a long service life.

[0025] Specifically, the upper pressure system 1 includes an upper pressure sliding plate 11 and several guide sleeves 12. Each guide sleeve 12 is installed on the upper pressure sliding plate 11. The upper pressure sliding plate 11 is slidably installed on the sliding frame 4 in the lifting direction through the guide sleeves 12, thereby realizing the lifting and lowering of the upper pressure sliding plate 11.

[0026] Specifically, the lower mold system 2 includes a lower template 20 and several forming cylinders 21. Each forming cylinder 21 has a silicone sheet installed on the top of its output end. The forming cylinders 21 are continuously distributed on the lower template 20 in four directions. The lower template 20 is installed on the sliding frame 4. The cutting slit 22 is located on the lower template 20. Each forming cylinder 21 is independently controlled to lift and lower, thereby generating cavities of different shapes through the silicone sheet. This allows the lower mold system 2 to deform according to the different shapes of the workpiece. The above structure of the lower mold system 2 can be realized using commercially available flexible molds, which is existing technology and will not be described in detail here.

[0027] Specifically, the lateral movement power system 3 includes a lateral movement power motor 31, a lateral movement screw 32, and a lateral movement slider 33. The lateral movement slider 33 is installed at the bottom of the sliding frame 4. The lateral movement screw 32 is connected to the sliding frame 4 through a threaded drive. The lateral movement screw 32 is installed at the output end of the lateral movement power motor 31 to realize the translation of the sliding frame 4.

[0028] Specifically, the sliding frame 4 includes a sliding base 41 and several guide columns 43. The guide columns 43 are arranged parallel to each other on the sliding base 41. The sliding base 41 is connected to the transverse motion force system 3. The upper pressing system 1 is slidably installed on the sliding frame 4 in the lifting direction. The lower mold system 2 is installed on the guide columns 43. The sliding frame 4 provides a mounting support for the upper pressing system 1 and the lower mold system 2.

[0029] Specifically, the mold pressing power device 6 is a pressing power cylinder that drives the upper pressing system 1 to rise and fall, facilitating the insertion and removal of the sponge.

[0030] Specifically, the gap between the output end of the vibration motor 553 and the vibration clutch block 552 is 0.5 mm. That is to say, after the elastic mounting plate 551 deforms by 0.5 mm, the vibration clutch block 552 and the output end of the vibration motor 553 will come into contact and transmit vibration, so as to realize the transmission between the vibration clutch block 552 and the vibration motor 553 after the cutting rope 52 is subjected to force due to the cutting action.

[0031] The aforementioned gap can also be 0.8 mm or 1 mm, meaning the gap can be in the range of 0.5 mm to 1 mm.

[0032] The cutting process of sponge shaping and cutting equipment includes the following steps: S1: The sponge is placed on the lower mold system 2, and the upper pressing system 1 is lowered by the mold pressing power device 6 to press the sponge onto the lower mold system 2; S2: The lateral movement force system 3 drives the sliding frame 4 to slide, which in turn causes the sponge and the cutting rope 52 to slide against each other; S3: After the cutting rope 52 is subjected to force, it pulls the vibration clutch 552, and the elastic mounting plate 551 deforms, which in turn makes the traction vibration clutch 552 contact the output end of the vibration motor 553 and thus transmit vibration. S4: After the cutting is completed, the cutting rope 52 is no longer under force, and the elastic mounting plate 551 drives the vibration clutch block 552 to disengage from the output end of the vibration motor 553.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
