Description

Technical Field

[0001] This invention relates to the field of sponge processing technology, and in particular to a molding and processing equipment and method for multilayer memory foam. Background Technology

[0002] Memory foam refers to polyether-type polyurethane foam with slow rebound mechanical properties, and belongs to special foams.

[0003] In the current production process, most foamed sponges are injected into molds to form the final product. When further processing is required, the sponge is heated and cooled to achieve a certain degree of hardness and stability before further processing.

[0004] Currently, most multi-layer memory foams are made by stacking multiple layers of foam with different properties, giving the foam more diverse functions and properties.

[0005] After being stacked and shaped, the multi-layered sponge still needs to be cut according to the predetermined size and shape. During the process, the sponge needs to be fixed and cut using cutting structures such as blade wheels and laser cutting. Multi-layered sponges are taller than ordinary sponges. At the same time, due to the strong shrinkage of the sponge itself, when moving and cutting, after the upper layer is cut, the sponge at the cutting position is prone to longitudinal shrinkage and excessive opening and dispersion to both sides. As a result, when the lower layer of sponge is cut, it is bent and pulled by the upper layer of sponge, affecting the flatness of the cut. Summary of the Invention

[0006] This invention provides a molding and processing equipment and method for multi-layer memory foam. By setting a bottom suction cup structure on the belt, the foam is locked in position on the belt by suction. Then, by using suction cup structures on both sides of the cutting structure, the bottom and top suction cups form a counter-suction locking effect on the upper and lower sides of the foam. Thus, when cutting the foam, the cut part of the foam is reduced in shrinkage under the suction of the top suction cup, thereby avoiding excessive opening of the cutting position and affecting the flatness of the lower layer of foam, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides a molding and processing equipment for multi-layer memory foam, including a transport base, the transport base including a transport platform for transporting multi-layer memory foam, and further including an adjustment component disposed at the end of the transport base, a foam locking component disposed below the transport platform, and a ceiling-mounted shaping mechanism disposed at the end of the transport base.

[0008] The movable end of the adjusting component is provided with a lifting cutting mechanism, which includes a cutting line for vertically cutting the sponge.

[0009] The ceiling-mounted shaping mechanism is located on both sides of the cutting line. The ceiling-mounted shaping mechanism includes an outer contour shaping component disposed on both sides of the cutting line and a driving component for driving the outer contour shaping component to move downward.

[0010] A suction enhancement mechanism is provided at the position directly opposite to the sponge locking component and the outer contour shaping component, and a suction shaping effect is formed on the sponge below the sponge on both sides of the cutting line. The outer contour shaping component includes an upper suction shaping plate that fits on the upper part of the sponge on both sides of the cutting line. The suction area of ​​the upper suction shaping plate is directly opposite the suction enhancement mechanism, and the suction strength decreases as it moves away from the cutting position. Thus, when the cutting line moves down to cut the sponge, it forms opposing suction shaping on the cutting position to avoid the sponge being pulled and deformed at the cutting position.

[0011] The bottom wall of the upper blister tray has a groove, and the inner wall of the groove decreases in a stepped manner. The outer contour shaping part also includes a suction hose and a suction component connected to the upper blister tray. The suction component is located on one side of the transport base. One end of the suction hose is connected to the upper blister tray, and the other end is connected to the suction component.

[0012] The suction hose is connected to the upper blister pack with multiple thin tubes, which are connected in a stepped manner to the top groove of the upper blister pack. This results in a stepped arrangement of suction points within the groove of the upper blister pack. The suction points closer to the cutting position are positioned lower within the upper blister pack, ensuring that when the upper blister pack is attached to the top surface of the sponge, the suction force is greater closer to the cutting position. This stepped decrease in suction force can specifically suppress deformation at the cutting point, ensuring the flatness of the cut and especially guaranteeing the cutting accuracy of the lower layer of sponge.

[0013] The surface of the conveying platform is provided with air holes, and the suction enhancement mechanism includes a suction base that fits into the bottom of the conveying platform. The suction base is connected to the suction component through a pipe, so that a downward suction sponge locking area is formed on the conveying platform.

[0014] The ceiling-mounted shaping mechanism also includes an edge-suction assembly located at the edge of the conveying platform. The edge-suction assembly includes side suction cups and a connecting tube. The side suction cups are arranged in pairs, respectively attached to the two sides of the top surface of the conveying platform. The suction ends of the two side suction cups face each other, and the suction position is located directly below the cutting line. The side suction cups have gaps, which are located on the path of the downward movement of the cutting line. One end of the connecting tube is connected to the side suction cups, and the other end is connected to the suction component. When the sponge is transported by the conveying platform to below the cutting line, the cutting line moves downward and completes the cutting. At this time, the two side suction cups perform opposing suction on both sides of the sponge, helping to shape the sides of the sponge and preventing the sides of the sponge from being stretched and deformed due to the cutting.

[0015] In the above technical solution, the upper suction cup adsorbs the top of the sponge, and the lower suction base adsorbs the bottom through the air holes of the conveying platform, forming a stable constraint in the vertical direction. The side suction cup group suctions in opposite directions directly below the cutting line to prevent the sponge from deforming due to cutting and pulling, thus achieving three-dimensional shaping protection. The opposing suction field formed on both sides of the cutting line effectively counteracts the sponge's own contraction force and prevents the cut from opening too much.

[0016] As a further improvement to this technical solution, the driving component includes a limiting ring frame, an adjusting push rod, and a guide. The limiting ring frame is located at the end of the transport base, and vertical guide grooves are provided on the vertical frames on both sides of the limiting ring frame. The two ends of the upper blister pack are slidably installed in the guide grooves on both sides of the limiting ring frame. The adjusting push rod is located at the end of the limiting ring frame, and the output end of the adjusting push rod is connected to the upper blister pack, thereby allowing the upper blister pack to move up and down within the limiting ring frame. The guide is located in the guide grooves on both sides of the limiting ring frame and acts on the upper blister pack, enabling the upper blister pack to move up and down within the limiting ring frame via the adjusting push rod, thereby adjusting the distance between the upper blister pack and the conveying platform according to the height of the multi-layer sponge.

[0017] In the above technical solution, the height of the upper blister plate can be adjusted by the drive component to adapt to multi-layered sponges of different thicknesses.

[0018] As a further improvement to this technical solution, the adjusting component includes a positioning column, a lifting slide, and a drive push rod. The positioning columns are arranged in pairs on both sides of the transport base. The lifting slide is slidably mounted on the positioning column. The cutting line is located at the end of the lifting slide and directly above the conveying platform. The drive push rod is located at the edge of the transport base, and its output end is connected to the lifting slide, so that the drive push rod can drive the lifting slide to slide along the positioning column, thereby driving the cutting line to rise and fall, and completing the cutting of the sponge on the conveying platform.

[0019] The top edge of the transport base is provided with a guide frame to guide the sponge in, and the end of the guide frame is provided with a shield to block the edge of the transport platform, so as to form a guide space on the transport platform.

[0020] The present invention also provides a processing method based on the above-mentioned molding and processing equipment for multilayer memory foam, comprising the following steps:

[0021] S1. The multi-layer sponge is attached to the conveyor platform for transportation, allowing the sponge to be transported below the cutting line;

[0022] S2. Start the control push rod to drive the upper blister pack to move down within the limit ring frame, so that the upper blister pack is attached to the top surface of the sponge. Start the suction device to make the suction area of ​​the upper blister pack form a suction and shaping of the sponge on both sides of the cutting position. In addition, the operation of the suction device will also drive the suction base to generate a downward suction force, thereby forming a counter-suction and shaping of the upper and lower sides of the sponge.

[0023] S3. Then, through the operation of the suction component, the side suction cups generate suction force. At this time, the two side suction cups complete the opposite suction and shaping on both sides of the sponge.

[0024] S4. The cutting mechanism is controlled to move downward by the adjusting component, so that the cutting line cuts the shaped sponge. During the process, the cutting line cuts the sponge, and the shaped sponge will reduce the shrinkage range, so as to avoid the cutting position being too open and affecting the cutting flatness of the lower layer of sponge.

[0025] S5. Turn off the suction device and restart the conveyor platform. The cut sponge will be transported and exported from the other side.

[0026] Compared with the prior art, the present invention provides a molding and processing equipment and method for multilayer memory foam and its deodorization process, which has the following beneficial effects:

[0027] This invention, through the cooperation of an upper forming plate, a lower suction enhancement mechanism, and a suction edge assembly, forms a three-dimensional suction shaping effect at the sponge cutting location. Combined with the stepped grooves inside the forming plate and the stepped distribution of suction hoses, a stepped suction field is formed above the cut, with stronger suction near the cut and weaker suction further away. This stabilizes the sponge structure at the moment of cutting, preventing excessive expansion of the cut due to the sponge's own deformation after cutting, and avoiding problems such as cutting deviation caused by cut deformation.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Reference Figures 1 to 8 As shown, the present invention provides a molding and processing equipment and method for multi-layer memory foam. In order to form a suction shaping effect at the cut of the multi-layer foam when cutting thicker multi-layer foam, and to prevent the cut from being excessively opened by the foam's own contraction during the cutting process, thereby affecting the flatness of the cut when cutting the lower layer of foam, the present invention includes a transport base 1. The transport base 1 includes a transport platform 11 for transporting multi-layer memory foam, and also includes an adjustment component 3 at the end of the transport base 1, a foam locking component 5 below the transport platform 11, and a suction shaping mechanism 6 at the end of the transport base 1.

[0039] The moving end of the adjusting component 3 is provided with a lifting cutting mechanism 4, which includes a cutting line 41 for cutting the sponge vertically.

[0040] The ceiling-mounted shaping mechanism 6 is located on both sides of the cutting line 41;

[0041] like Figure 3As shown, the ceiling-mounted shaping mechanism 6 includes an outer contour shaping component 61 disposed on both sides of the cutting line 41, a driving component 62 for driving the outer contour shaping component 61 to move downward, and a suction edge assembly 63 disposed at the edge of the conveying platform 11.

[0042] A suction enhancement mechanism 51 is provided at the position directly opposite to the sponge locking part 5 and the outer contour shaping part 61, and forms a suction shaping effect on the sponge below the sponge on both sides of the cutting line 41. The outer contour shaping part 61 includes an upper suction shaping plate 611 that fits above the sponge on both sides of the cutting line 41. The suction area of ​​the upper suction shaping plate 611 is directly opposite to the suction enhancement mechanism 51, and the suction strength decreases as it moves away from the cutting position. Thus, when the cutting line 41 moves down to cut the sponge, it forms opposing suction shaping at the cutting position to avoid the sponge being pulled and deformed at the cutting position.

[0043] like Figure 8 As shown, the bottom wall of the upper blister tray 611 has a groove, and the inner wall of the groove decreases in a stepped manner. The outer contour shaping part 61 also includes a suction hose 612 and a suction component 7 connected to the upper blister tray 611. The suction component 7 is located on one side of the transport base 1. One end of the suction hose 612 is connected to the upper blister tray 611, and the other end is connected to the suction component 7.

[0044] The suction hose 612 is connected to the upper blister tray 611 with multiple thin tubes, which are connected in a stepped manner to the top groove of the upper blister tray 611. This results in the suction points in the groove of the upper blister tray 611 being arranged in a stepped manner. The closer the suction point is to the cutting position, the lower its position is in the upper blister tray 611. This makes the suction force greater closer to the cutting position when the upper blister tray 611 is attached to the top surface of the sponge.

[0045] The stepped groove on the bottom wall of the upper vacuum forming plate 611, combined with multiple sets of suction hoses 612, achieves a gradient distribution of strong suction near the cutting point and weak suction far from the cutting point. This specifically suppresses deformation at the near and far cutting points, thereby preventing the sponge cut from being over-expanded and affecting the deformation of the lower layer of sponge, ensuring the cutting accuracy of the lower layer of sponge, and thus avoiding cutting deviation or delamination problems caused by cut deformation.

[0046] The surface of the conveying platform 11 is provided with air holes. The suction enhancement mechanism 51 includes a suction base 511 that fits into the bottom of the conveying platform 11. The suction base 511 is connected to the suction component 7 through a pipe, so that a downward suction sponge locking area is formed on the conveying platform 11. The suction enhancement mechanism 51 is directly opposite the upper suction shaping plate 611, forming an upper and lower suction field to enhance the shaping effect.

[0047] like Figure 5As shown, the suction assembly 63 includes side suction cups 631 and connecting tubes 632. The two side suction cups 631 are arranged in a group and are respectively attached to the two sides of the top surface of the conveying platform 11. The suction ends of the two side suction cups 631 face each other and the suction position is located directly below the cutting line 41. The side suction cups 631 have gaps, and the gaps are located on the path of the downward movement of the cutting line 41. One end of the connecting tube 632 is connected to the side suction cups 631, and the other end is connected to the suction component 7. When the sponge is transported by the conveying platform 11 to below the cutting line 41, the cutting line 41 moves down to complete the cutting. At this time, the two side suction cups 631 complete the opposite suction on both sides of the sponge, which helps to shape the side of the sponge and prevents the side of the sponge from being stretched and deformed due to the cutting.

[0048] It should be clarified that the side suction cup 631 has a gap for the cutting line 41 to move downward, ensuring that the cutting is not disturbed, while providing lateral suction and shaping at the position directly below the cutting line 41 to prevent edge deformation.

[0049] like Figure 6 As shown, the driving component 62 includes a limiting ring frame 621, an adjusting push rod 622, and a guide component 623. The limiting ring frame 621 is located at the end of the transport base 1, and vertical guide grooves are provided on the vertical frames on both sides of the limiting ring frame 621. The two ends of the upper blister tray 611 are slidably installed in the guide grooves on both sides of the limiting ring frame 621. The adjusting push rod 622 is located at the end of the limiting ring frame 621, and the output end of the adjusting push rod 622 is connected to the upper blister tray 611, thereby allowing the upper blister tray 611 to move up and down within the limiting ring frame 621. The guide component 623 is located in the guide grooves on both sides of the limiting ring frame 621 and acts on the upper blister tray 611. It can drive the upper blister tray 611 to move up and down within the limiting ring frame 621 through the adjusting push rod 622, thereby adjusting the distance between the upper blister tray 611 and the conveying platform 11 according to the height of the multi-layer sponge.

[0050] like Figure 2 and Figure 4 As shown, the adjusting component 3 includes a positioning column 31, a lifting slide 32, and a drive push rod 33. The positioning columns 31 are arranged in pairs on both sides of the transport base 1. The lifting slide 32 is slidably mounted on the positioning column 31. The cutting line 41 is located at the end of the lifting slide 32 and is located directly above the conveying platform 11. The drive push rod 33 is located at the edge of the transport base 1 and its output end is connected to the lifting slide 32, so that the drive push rod 33 can drive the lifting slide 32 to slide along the positioning column 31, thereby driving the cutting line 41 to rise and fall, and completing the cutting of the sponge on the conveying platform 11.

[0051] A guide frame 2 is provided at the top edge of the transport base 1 to guide the sponge in, and a shielding plate is provided at the end of the guide frame 2 to shield the edge of the transport platform 11, so that a guide space is formed on the transport platform 11.

[0052] Working principle: The sponge is inserted into the top surface of the transport base 1 via the guide frame 2. The conveyor platform 11 is started to transport the multi-layer sponge to below the cutting line 41. At this time, the control push rod 622 can be activated to drive the upper blister forming plate 611 to move up and down on the limiting ring frame 621, so that the upper blister forming plate 611 is respectively attached to both sides of the top surface of the sponge. The suction component 7 is activated. At this time, the suction area of ​​the upper blister forming plate 611 forms a suction and shaping effect on the sponge on both sides of the cutting position, driving the suction base 511 to generate a downward suction force, which together forms a counter-suction shaping effect on the upper and lower sides of the sponge. In addition, the side suction cups 631 generate suction to complete the opposite suction shaping on both sides of the sponge. The drive push rod 33 is activated, driving the lifting slide 32 to slide down along the positioning column 31. At this time, the cutting line 41 moves down synchronously and completes the cutting of the sponge. During the cutting process, since the sponge is shaped by suction in the three-dimensional space of up, down, left and right, the sponge will reduce the shrinkage range, avoiding excessive opening of the cutting position and affecting the cutting flatness of the lower layer of sponge. After the flat cutting is completed, the suction component 7 is turned off, and the conveying platform 11 is started to transport the cut sponge out.

[0053] A processing method based on the above-mentioned molding and processing equipment for multilayer memory foam includes the following steps:

[0054] S1. Transport the multi-layer sponge onto the conveying platform 11, allowing the sponge to be transported below the cutting line 41.

[0055] S2. Start the control push rod 622 to drive the upper blister forming plate 611 to move down within the limiting ring frame 621, so that the upper blister forming plate 611 fits against the top surface of the sponge. Start the suction component 7 so that the suction area of ​​the upper blister forming plate 611 forms suction and shaping of the sponge on both sides of the cutting position. In addition, the operation of the suction component 7 will also drive the suction base 511 to generate downward suction, thereby forming opposing suction and shaping of the upper and lower sides of the sponge.

[0056] S3. Then, through the operation of the suction component 7, the side suction cups 631 generate suction force. At this time, the two side suction cups 631 complete the opposite suction and shaping on both sides of the sponge.

[0057] S4. The adjusting component 3 controls the cutting mechanism 4 to move down, so that the cutting line 41 cuts the shaped sponge. During the process, the cutting line 41 cuts the sponge, and the shaped sponge will reduce the shrinkage range, so as to avoid the cutting position being too open and affecting the cutting flatness of the lower layer of sponge.

[0058] S5. Close the suction unit 7 and restart the conveyor platform 11. The cut sponge is then transported and exported from the other side.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
