Description

Technical Field

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

[0002] A sponge cutting machine is a professional molding and processing equipment for sponge materials. Its core function is to cut whole pieces of sponge raw materials into blanks of preset shapes and sizes. It is especially suitable for processing sponge products with customized irregular structures, such as children's pillow cores. To adapt to ergonomic design, children's pillow cores often adopt irregular structures such as wave-shaped, arc-shaped, and curved surfaces. Manual cutting cannot guarantee the accuracy of curvature and uniformity of size. Sponge is soft, and manual cutting is prone to rough edges and shedding. However, the hot-press sponge cutting machine can achieve integrated melting and cutting and edge shaping through high temperature, making the cut edges smooth and regular.

[0003] To ensure softness and fit, children's pillow core production commonly uses slow-rebound, low-density soft sponge as raw material. This type of sponge has a low melting point and strong molecular adhesion, making it more prone to melting and adhesion problems under high-temperature processing. During operation, the lower die edge of the hot-press cutting machine needs to be heated to 160-220℃ to achieve melting and cutting. During this high-temperature contact, the pillow core sponge quickly melts into a viscous substance. Under the combined effects of surface tension and high-temperature adsorption, it easily adheres to and accumulates on the high-temperature cutting edge and the inner wall of the cavity. As mass production continues, the adhesive material thickens and hardens, directly causing product quality problems such as uneven cut edges, curvature deviations, and contour deformation. It also causes secondary adhesion between the subsequently processed sponge blank and the cutting edge and cavity, leading to difficulties in material handling, equipment malfunctions, and severely reduced production efficiency. Furthermore, the repeated accumulation of adhesive material exacerbates cutting edge wear and shortens the mold's lifespan. Therefore, based on the above problems, this invention provides a sponge cutting machine to meet the requirements. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a sponge cutting machine. By setting up a sliding component and an anti-sticking component, the sliding component can adaptively conform to the arc-shaped slide rail, ensuring the continuity and stability of the movement; the anti-sticking component can avoid the sponge to be cut, so as not to affect the normal cutting of the sponge, and can also actively scrape off the adhesive material adhering to the inner wall of the cavity cutting edge after cutting, and perform secondary cleaning of the scraping tool, ensuring the cutting accuracy and product consistency. Through the above settings, the problem of low melting point high viscosity soft sponge used for children's pillow cores being prone to sticking and accumulating on the cutting edge when melted by the high temperature of the cutting edge of a hot press cutting machine can be solved.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A sponge cutting machine includes a body with an upper mold and a lower mold that cooperate with each other. The upper mold is a wooden punch, and the lower mold is a metal die. A sliding component is provided on the lower mold to provide movement guidance and is connected to the lower mold. An anti-stick component is also included to clean residual adhesive material and is connected to the sliding component.

[0006] Optionally, the sliding assembly includes a groove formed at the bottom of the lower mold, a slide rail fixedly connected to the groove, rollers slidably connected to both sides of the slide rail, a bracket rotatably connected to the top of the rollers, an electric slider fixedly connected to the top of the bracket, and an anti-stick component fixedly connected to one side of the electric slider.

[0007] Optionally, the lower mold has a cavity cutting edge, the groove is located at the concentric position of the cavity cutting edge, and the groove is a large-size structure with the same contour as the cavity cutting edge.

[0008] Optionally, the slide rail is located at the center of the groove, and the cross-section of the slide rail has oblique protrusions on both sides near the roller.

[0009] Optionally, the cross-sectional diameter at the center of the roller is smaller than the cross-sectional diameter at both ends of the roller, and the diameter at both ends of the roller gradually decreases towards the center.

[0010] Optionally, the machine body is further provided with a support pad, and a leveling pad is fixedly connected to the top of the support pad. The leveling pad and the support pad are located directly below the lower mold.

[0011] Optionally, the anti-sticking component includes a cleaning scraper fixedly connected to one side of the electric slider. The cleaning scrapers are symmetrically distributed, and arc-shaped clamps are fixedly connected to the opposite surfaces of the cleaning scrapers. An anti-sticking scraper is also slidably connected to one side of the electric slider. A rod is fixedly connected to the top center of the anti-sticking scraper, and symmetrically distributed lifting sliders are fixedly connected to the side of the anti-sticking scraper near the electric slider.

[0012] Optionally, both the anti-stick scraper and the cleaning scraper have a V-shaped cross-section, and the free ends of both the anti-stick scraper and the cleaning scraper do not contact the inner wall of the cavity cutting edge.

[0013] Optionally, the arc-shaped clamp is provided with uniformly distributed weakening grooves, the arc-shaped clamp has an arc-shaped curved surface structure, and the spacing between the opposing arc-shaped clamps gradually decreases from top to bottom.

[0014] Optionally, the outer diameter of the insertion rod gradually decreases from top to bottom, and a groove is provided on one side of the anti-stick scraper corresponding to the position of the lifting slider, and the outer diameter of the lifting slider is adapted to the inner wall size of the groove.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a sliding component and an anti-sticking component, the sliding component can adaptively fit the arc-shaped slide rail, ensuring the continuity and stability of the movement. During the sliding scraping process, it can adapt to the shape of the cavity cutting edge, making it easier to clean the sticky material. The anti-sticking component can avoid the sponge to be cut, so as not to affect the normal cutting of the sponge. It can also actively scrape off the sticky material adhering to the inner wall of the cavity cutting edge after cutting, and perform secondary cleaning of the scraping tool, ensuring the cutting accuracy and product consistency.

[0016] By setting up a combination of slide rails and rollers, it can achieve adaptive smooth movement along an arc-shaped trajectory. The multi-wheel load distribution makes the force more even, improves the structural durability, and can accurately fit the contour of the cavity and cutting edge, efficiently remove sticky material, avoid stress concentration, and ensure the load-bearing capacity and operational stability of the equipment on the arc path, ultimately improving cutting accuracy and production efficiency.

[0017] By combining an anti-stick scraper, insert rod, and arc-shaped clamp, along with a spring, precise and flexible avoidance of the pillow core can be achieved without interfering with normal cutting. The conical structure of the insert rod and the gradual spacing of the arc-shaped clamp allow the arc-shaped clamp to deform smoothly after being compressed. The distribution of the weakening groove further enhances its deformation flexibility, ensuring the overall structural stability and service life, and adapting to the avoidance requirements of pillow core cutting.

[0018] By setting up a cleaning scraper and an anti-stick scraper in combination, the surface material of the anti-stick scraper can be cleaned a second time when it is squeezed and slid down. This effectively ensures the surface cleanliness of the anti-stick scraper before the next cleaning, avoids the residue of the material affecting the subsequent scraping effect on the inner wall of the cavity cutting edge, improves the thoroughness of the material cleaning, and ensures the operational stability of the anti-stick component. This makes the subsequent scraping of the material on the cavity cutting edge more efficient, and indirectly maintains the accuracy and efficiency of the pillow core cutting.

[0028] like Figures 1 to 10 As shown, an embodiment of the present invention provides a sponge cutting machine, including a machine body 1. The machine body 1 is provided with an upper mold 2 and a lower mold 3, which cooperate with each other. The upper mold 2 is a wooden punch, and the lower mold 3 is a metal die. The machine body 1 is also provided with a support plate 5. A leveling plate 4 is fixedly connected to the top of the support plate 5. The leveling plate 4 and the support plate 5 are located directly below the lower mold 3 (e.g., ...). Figures 1 to 4As shown), the lower mold 3 is equipped with a sliding component, which provides a guide for movement and is connected to the lower mold 3; an anti-stick component is used to clean residual adhesive and is connected to the sliding component. The sponge cutting machine provided in this application is suitable for the production and processing of hot-pressed fused sponge cores. The working principle of the hot-pressed fused sponge cutting machine is disclosed as prior art and will not be described in detail. In actual products, the sponge is bonded to the mold, and the metal cavity cutting edge 18 of the lower mold 3 is heated to 160-220℃ by the heating tube. The upper mold 2 presses down to press the sponge tightly against the cutting edge. The high temperature melts the sponge at the contact point, and the pressure is used to achieve fused cutting. At the same time, the melted edge is shaped, making the edge of the pillow core smooth and free of debris. Precisely forming irregular contours, existing sponge hot-press melting and cutting machines have a core structure including a hydraulic or pneumatic drive mechanism, an upper mold 2 with a wooden forming punch, a lower mold 3 with a built-in metal heating cutting edge cavity, a slide table that drives the mold to open and close, and a temperature control system for regulating the cutting edge temperature. In use, the sponge blank is placed on the cutting edge 18 of the cavity of the lower mold 3, the slide table pushes the mold to the processing position, the drive mechanism drives the upper mold 2 to press down, the punch of the upper mold 2 presses the sponge tightly onto the high-temperature cutting edge of the lower mold 3, the cutting edge melts the sponge and shapes the contour, after completion, the upper mold 2 is lifted, the slide table is reset, and the formed pillow core is removed. Here, the specific structure and working principle of the slide table and drive mechanism are disclosed as existing technology and will not be described in detail.

[0029] By setting up sliding and anti-stick components, the sliding component can adaptively fit the arc-shaped slide rail 7, ensuring the continuity and stability of the movement. During the sliding scraping process, it can adapt to the shape of the cavity cutting edge 18, making it easier to clean the sticky material. The anti-stick component can avoid the sponge to be cut, so as not to affect the normal cutting of the sponge. It can also actively scrape off the sticky material on the inner wall of the cavity cutting edge 18 after cutting, and perform secondary cleaning of the scraping tool, ensuring the cutting accuracy and product consistency.

[0030] As one implementation method in this embodiment, such as Figures 1 to 10 As shown, the sliding assembly includes a groove 6 formed at the bottom of the lower mold 3. A cavity cutting edge 18 is formed on the lower mold 3. The groove 6 is located concentrically with the cavity cutting edge 18, and the groove 6 is a large-size structure with the same contour as the cavity cutting edge 18. A slide rail 7 is fixedly connected to the groove 6. Rollers 9 are slidably connected to both sides of the slide rail 7. The slide rail 7 is located at the center of the groove 6. The cross-section of the slide rail 7 has oblique protrusions on both sides near the rollers 9. The cross-sectional diameter at the center of the rollers 9 is smaller than the cross-sectional diameter at both ends of the rollers 9, and the diameter at both ends of the rollers 9 gradually decreases towards the center. A bracket 8 is rotatably connected to the top of the rollers 9. An electric slider 10 is fixedly connected to the top of the bracket 8. An anti-stick component is fixedly connected to one side of the electric slider 10.

[0031] Specifically, the lower mold 3 is made of metal, while the upper mold 2, leveling plate 4, and support plate 5 are all made of wood. The lower mold 3 is made of metal to meet the requirements of high-temperature melting and cutting. Metal has good thermal conductivity, high temperature resistance, and high hardness, which can stably transfer heat to achieve sponge melting and cutting. At the same time, it is wear-resistant and deformation-resistant, ensuring the cutting accuracy of the blade. The upper mold 2, leveling plate 4, and support plate 5 are made of wood because wood has good heat insulation, which can reduce high temperature conduction and avoid heat damage to equipment parts. It is also lightweight, has good cushioning, can fit irregularly shaped pillow cores, and can reduce mold processing costs. The upper mold 2 is located directly above the lower mold 3, and the leveling plate 4 and support plate 5 are located directly below the lower mold 3. The slide rail 7 is located at the center of the groove 6. The dimensions between the two sides of the slide rail 7 and the inner wall of the groove 6 are adapted to the outer contour dimensions of the roller 9, ensuring that the roller 9 slides smoothly on the path of the slide rail 7. The groove 6 and the cavity cutting edge 18 are concentric, and the groove 6 is a large-size structure with the same contour as the support 8 (e.g., Figures 5 to 6 As shown in the figure, this ensures that the anti-stick component fits snugly against the cavity cutting edge 18, thereby better removing the sticky material. The large-size setting of the groove 6 and the cavity cutting edge 18 with the same contour can be adaptively modified according to the contour of the mold. The purpose is to ensure that the groove 6 always maintains a concentric and contoured relationship with the cavity cutting edge 18, but the groove 6 is large in size, so as to ensure that the anti-stick component can fit against the inner wall of the cavity cutting edge 18 during sliding. By using multiple rollers 9, the load can be distributed among multiple rollers, making the force on each roller 9 more uniform and reducing single-point wear. Moreover, the design of multiple rollers cooperating to bear the load can withstand greater vertical and lateral loads on the arc trajectory, and there will be no stress concentration due to the curvature of the track.

[0032] By setting up the slide rail 7 and roller 9 in combination, it can achieve adaptive smooth movement along the arc trajectory. The multi-wheel load distribution makes the force more uniform, improves the structural durability, and can accurately fit the contour of the cavity cutting edge 18, efficiently remove sticky material, avoid stress concentration, ensure the load-bearing capacity and operational stability of the equipment on the arc path, and ultimately improve cutting accuracy and production efficiency.

[0033] As one implementation method in this embodiment, such as Figures 1 to 10As shown, the anti-sticking component includes a cleaning scraper 14 fixedly connected to one side of the electric slider 10. The cleaning scrapers 14 are symmetrically distributed, and arc-shaped clamps 15 are fixedly connected to opposite surfaces of the cleaning scrapers 14. Evenly distributed weakening grooves 16 are formed through the arc-shaped clamps 15. The arc-shaped clamps 15 have an arc-shaped curved surface structure, and the spacing between the opposing arc-shaped clamps 15 gradually decreases from top to bottom. An anti-sticking scraper 11 is also slidably connected to one side of the electric slider 10. The cross-sections of the anti-sticking scraper 11 and the cleaning scraper 14 are shown. Both are V-shaped structures. The free ends of the anti-stick scraper 11 and the cleaning scraper 14 do not contact the inner wall of the cavity cutting edge 18. A rod 12 is fixedly connected to the top center of the anti-stick scraper 11. A symmetrically distributed lifting slider 13 is fixedly connected to the side of the anti-stick scraper 11 near the electric slider 10. The outer diameter of the rod 12 gradually decreases from top to bottom. A groove 17 is provided on one side of the anti-stick scraper 11 corresponding to the position of the lifting slider 13. The outer diameter of the lifting slider 13 is adapted to the inner wall size of the groove 17.

[0034] Furthermore, there is a certain gap between the lower mold 3 and the leveling pad 4. The length of the anti-stick scraper 11 is greater than the length of the electric slider 10. A spring is fixedly connected to the bottom of the inner wall of the slide groove 17. The top of the spring is fixedly connected to the bottom of the lifting slider 13. The spring is hidden and stored in the inner wall of the slide groove 17. When the spring is in a free state, the top of the anti-stick scraper 11 is at the same height as the top of the lower mold 3. The bottom of the insert rod 12 is located between the arc-shaped clamping plates 15, and the bottom of the insert rod 12 does not contact the arc-shaped clamping plates 15 (e.g., Figure 7 As shown, when the upper mold 2 begins to press down, the pillow core to be cut is squeezed and moves downward. At the same time, the anti-stick scraper 11 is also squeezed downward by the pillow core. During the process of the anti-stick scraper 11 driving the insert rod 12 downward, the spring will be compressed. Since the insert rod 12 is a structure that gradually tapers from top to bottom, and the spacing between the opposing arc-shaped clamps 15 gradually decreases from top to bottom, the arc-shaped clamps 15 will be squeezed by the insert rod 12 and deformed towards the cleaning scraper 14. The spring and the cooperation between the insert rod 12 and the arc-shaped clamps 15 are used to avoid the pillow core. At this time, the bottom of the anti-stick scraper 11 still does not contact the support pad 5 to ensure that the anti-stick scraper 11 is not squeezed and deformed. Moreover, the weakening grooves 16 evenly distributed on the arc-shaped clamps 15 make the arc-shaped clamps 15 more likely to deform after being squeezed by the insert rod 12.

[0035] By setting up the anti-stick scraper 11, the insertion rod 12 and the arc-shaped clamping plate 15, and with the help of the spring, precise and flexible avoidance of the pillow core can be achieved without interfering with normal cutting. The conical structure of the insertion rod 12 and the gradual spacing of the arc-shaped clamping plate 15 cooperate to allow the arc-shaped clamping plate 15 to deform smoothly after being squeezed. The distribution of the weakening groove 16 further improves its deformation flexibility, ensures the stability of the overall structure and service life, and adapts to the avoidance requirements of pillow core cutting.

[0036] Furthermore, after cutting, the upper mold 2 is lifted upwards and the slide table is reset. The cut pillow core and the anti-stick scraper 11 are no longer squeezed by the upper mold 2. The anti-stick scraper 11 will bounce upwards under the elastic recovery action of the spring and the arc-shaped clamping plate 15, thereby lifting the cut pillow core upwards, making it easier to remove the molded pillow core. Then, the electric slider 10 is activated, causing the electric slider 10 to slide along the path of the slide rail 7 for one revolution. The anti-stick scraper 11 is used to scrape off the material stuck to the inner wall of the cavity cutting edge 18. This is because after the material leaves the high-temperature processing area with the lower mold 3, the temperature drops rapidly, causing it to lose its stickiness and harden and solidify. The material becomes brittle and easily separates from the surface of the cavity cutting edge 18. At this point, a scraping operation can easily and completely remove the adhering material without leaving any debris. This high-efficiency cleaning also avoids damage to the cavity cutting edge 18, ensuring the accuracy of subsequent cutting processes. Here, the specific structure and working principle of the electric slider 10 are disclosed as existing technology and will not be elaborated further. Then, the cutting operation is repeated. When the upper mold 2 presses down again, the anti-stick scraper 11 is squeezed and slides downwards. The cleaning scraper 14 can scrape off the adhering material standing on the anti-stick scraper 11. The cleaning scraper 14 is located on both sides near the anti-stick scraper 11 (e.g., Figures 7 to 10 As shown, while the anti-stick scraper 11 slides downward, the cleaning scraper 14 cleans the material stuck on the anti-stick scraper 11 a second time, ensuring that the anti-stick scraper 11 is clean before the next cleaning, thus facilitating the treatment of adhesion on the cavity cutting edge 18.

[0037] By setting the cleaning scraper 14 to work in conjunction with the anti-stick scraper 11, the surface of the anti-stick scraper 11 can be cleaned a second time when it is squeezed down. This effectively ensures the surface cleanliness of the anti-stick scraper 11 before the next cleaning, avoids the residue of the scraper affecting the subsequent scraping effect on the inner wall of the cavity cutting edge 18, improves the thoroughness of the scraping, and ensures the operational stability of the anti-stick component. This makes the subsequent scraping of the cavity cutting edge 18 more efficient, and indirectly maintains the accuracy and efficiency of the pillow core cutting.

[0038] The working principle of the technical solution provided by this invention is as follows: In use, the sponge blank is placed on the cutting edge 18 of the lower mold 3 cavity. The slide pushes the mold to the processing position, and the drive mechanism drives the upper mold 2 to press down. The punch of the upper mold 2 presses the sponge tightly onto the high-temperature cutting edge of the lower mold 3. The anti-stick scraper 11 is also squeezed downward by the pillow core. During the downward movement of the anti-stick scraper 11 and the insert rod 12, the spring in the slide groove 17 is compressed. Since the insert rod 12 has a structure that gradually tapers from top to bottom, and the spacing between the opposing arc-shaped clamping plates 15 gradually decreases from top to bottom, the arc-shaped clamping plates 15 are squeezed by the insert rod 12 and deformed towards the cleaning scraper 14. The spring and the cooperation of the insert rod 12 and the arc-shaped clamping plates 15 are used to avoid the pillow core. At this time, the bottom of the anti-stick scraper 11 still does not contact the support pad 5. To ensure the anti-stick scraper 11 is not squeezed and deformed, and with evenly distributed weakening grooves 16 on the arc-shaped clamping plate 15, the arc-shaped clamping plate 15 is more prone to deformation after being squeezed by the insert rod 12. After cutting, the upper mold 2 is lifted upwards and the slide table is reset. The cut pillow core and the anti-stick scraper 11 are no longer squeezed by the upper mold 2. The anti-stick scraper 11 will bounce upwards under the elastic recovery action of the spring and the arc-shaped clamping plate 15, thereby lifting the cut pillow core upwards, making it easier to remove the molded pillow core. Then, the electric slider 10 is activated, causing the electric slider 10 to slide along the path of the slide rail 7 for one revolution. The slide rail 7 and the roller 9 work together to achieve adaptive and smooth movement along the arc-shaped trajectory. The multi-wheel load distribution makes the force more even, improves the structural durability, and can accurately fit the cavity cutting edge. The contour of the cavity 18 is efficiently cleaned by using the anti-stick scraper 11 to scrape off the material adhering to the inner wall of the cavity cutting edge 18. Because the material loses its stickiness and hardens after leaving the high-temperature processing zone with the lower mold 3, it becomes brittle and easily separates from the surface of the cavity cutting edge 18. Scraping at this time easily and thoroughly removes the material without leaving any debris. This high cleaning efficiency also avoids damage to the cavity cutting edge 18, ensuring the accuracy of subsequent cutting processes. The specific structure and working principle of the electric slider 10 are disclosed as existing technology and will not be elaborated further. The cutting process is then repeated. When the upper mold 2 presses down again, the anti-stick scraper 11 is squeezed and slides downwards. The cleaning scraper 14 scrapes off the material standing on the anti-stick scraper 11, thus cleaning the cavity cutting edge 18. The cleaning scraper 14 is positioned on both sides near the anti-stick scraper 11. As the anti-stick scraper 11 slides downwards, the cleaning scraper 14 performs a secondary cleaning of the material adhering to the anti-stick scraper 11, ensuring that the anti-stick scraper 11 is clean before the next cleaning. This facilitates the treatment of adhesions on the cavity cutting edge 18. The cleaning scraper 14 works in conjunction with the anti-stick scraper 11 to perform a secondary cleaning of the surface material when the anti-stick scraper 11 is compressed and slides down, effectively ensuring the surface cleanliness of the anti-stick scraper 11 before the next cleaning. This prevents material residue from affecting the subsequent scraping effect on the inner wall of the cavity cutting edge 18, improves the thoroughness of material cleaning, and ensures the operational stability of the anti-stick component. This makes the subsequent scraping of material from the cavity cutting edge 18 more efficient, indirectly maintaining the accuracy and efficiency of the pillow core cutting.This device not only adaptively conforms to the curved slide rail 7, ensuring continuous and stable movement, but also adapts to the shape of the cavity cutting edge 18 during the sliding scraping process, making it easier to clean up adhering material. It can also avoid obstructing the cutting of the sponge, preventing interference with its normal cutting. Furthermore, after cutting, it actively scrapes off the material adhering to the inner wall of the cavity cutting edge 18 and performs secondary cleaning of the scraping tool, ensuring cutting accuracy and product consistency.
