Description

Technical Field

[0001] This utility model relates to the field of furniture production equipment technology, and in particular to a cushion mold. Background Technology

[0002] Chair cushions typically use elastic materials like springs and foam pads to enhance comfort. During cushion manufacturing, the elastic material needs to be pre-compressed to maintain a certain amount of pre-compression, allowing the cushion to provide good elastic deformation and maintain its overall shape during use. The cushion mold has a relatively simple structure, with cavities for shaping the fabric and foam pads. Cushion production uses a semi-manual, semi-automatic method. The fabric, foam pad, and padding board are placed sequentially on the cushion mold. Then, the padding board is pressed down to compress the center of the fabric and foam pad into the cavity. The edges of the fabric are folded onto the padding board, completing the cushion's shaping. Next, the mold's position and orientation are manually adjusted so that the nailing device can nail the edges of the fabric to the padding board, or the nail gun is manually moved to different areas of the fabric edge to nail all edges to the padding board. Most of the work is done manually, resulting in low automation, a large workload for workers, high labor intensity, and requiring a certain level of skill. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Reference Figures 1 to 3 This utility model discloses a cushion mold, including a base plate 1 and a tray 2. The tray 2 is disposed on the base plate 1 and can rotate on the base plate 1 with the vertical direction as the rotation axis. The tray 2 is provided with a recessed cavity 21. The base plate 1 is provided with a rotation drive mechanism 11. The output end of the rotation drive mechanism 11 is connected to a fabric-flipping arm 111. The rotation drive mechanism 11 is used to drive the swing end of the fabric-flipping arm 111 to swing. The swing end of the fabric-flipping arm 111 swings from bottom to top and from outside to inside, so that the swing end of the fabric-flipping arm 111 moves from the area on the lower outer side of the tray 2 to the top of the tray 2. The swing end of the fabric-flipping arm 111 can fold the edge of the fabric to the upper surface of the pad. Alternatively, the rotation drive mechanism 11 is used to drive the swing end of the fabric-flipping arm 111 to swing in the opposite direction. The swing end of the fabric-flipping arm 111 swings from inside to outside and from top to bottom, so that the swing end of the fabric-flipping arm 111 returns from the top of the tray 2 to the area on the lower outer side of the tray 2.

[0021] When making the cushion, the swing end of the fabric-flipping arm 111 is located in the area on the lower outer side of the tray 2. The fabric block, sponge pad, and pad are placed on the center of the tray 2 in sequence, so that the tray 2 supports the fabric block, sponge pad, and pad placed from bottom to top. The center of the fabric block, sponge pad, and pad are directly opposite the cavity 21, and the edge of the fabric block extends to the outside of the tray 2 and rests on the swing end of the fabric-flipping arm 111. First, the pad is pressed down manually or using a pressing device, so that the center of the fabric block and sponge pad are retracted into the cavity 21. At this time, the edge of the fabric block is still resting on the swing end of the fabric-flipping arm 111. Then, the drive mechanism 11 is rotated. The swing end of the fabric-flipping arm 111 is driven to swing from bottom to top and from outside to inside. The swing end of the fabric-flipping arm 111 folds the edge of part of the fabric piece to the upper surface of the pad. Then, the rotary drive mechanism 11 drives the swing end of the fabric-flipping arm 111 to return to its original position. Then, the tray 2 is driven to rotate at a certain angle manually or by using a rotary drive device, so that the edge of the other part of the fabric piece is facing the fabric-flipping arm 111. The rotary drive mechanism 11 and the fabric-flipping arm 111 repeat the above actions to fold the edge of the other part of the fabric piece to the upper surface of the pad. In this way, all the edges of the fabric piece can be folded to the upper surface of the pad.

[0022] After some or all of the edges of the fabric piece are folded to the upper surface of the pad, the edges of the fabric piece on the upper surface of the pad can be nailed to the pad using a nailing device or a manual nail gun. In specific operation, the position of the nailing device or the handheld nail gun remains unchanged. When the edge of the fabric piece corresponding to the position of the nailing device or the handheld nail gun on the mold is folded to the pad, the nailing device or the handheld nail gun can nail the edge of the fabric piece to the pad. First, all the edges of the fabric piece can be folded to the pad, and then the tray 2 can be rotated so that all the edges of the fabric piece are facing the nailing device or the handheld nail gun in sequence. The nailing device or the handheld nail gun nails all the edges of the fabric piece to the pad in sequence. Alternatively, when the tray 2 is rotated, the rotary drive mechanism 11 and the fabric folding arm 111 fold all the edges of the fabric piece to the upper surface of the pad in sequence. During this process, the nailing device or the handheld nail gun simultaneously nails all the edges of the fabric piece to the pad in sequence.

[0023] The rotary drive mechanism 11, the fabric-flipping arm 111, and the rotatable tray 2 work together. The rotary drive mechanism 11 and the fabric-flipping arm 111 replace the manual folding of the fabric edges. By rotating the tray 2, the rotary drive mechanism 11 and the fabric-flipping arm 111 can fold all the edges of the fabric to the upper surface of the pad, and make all the edges of the fabric face the nailing device or hand-held nail gun in sequence. This makes it convenient for the nailing device or hand-held nail gun to nail all the edges of the fabric to the pad in sequence. There is no need to manually fold the edges of the fabric and move the entire mold, which reduces the amount of labor and the labor intensity of the workers, and can improve the efficiency of making cushions.

[0024] In addition, the mold, combined with the pressing equipment, rotary drive equipment and nailing device, can achieve a higher degree of semi-automation in the production of seat cushions, further liberating labor, improving productivity and production efficiency. The pressing equipment, rotary drive equipment and nailing device can all be existing equipment.

[0025] It is conceivable that the shape of the tray 2 can be set to square or round, and the shape of the tray 2 can be the same as or similar to the shape of the cushion. There are multiple rotary drive mechanisms 11 and multiple fabric-flipping arms 111. The multiple rotary drive mechanisms 11 and multiple fabric-flipping arms 111 are distributed along the periphery of the base plate 1. The multiple rotary drive mechanisms 11 and multiple fabric-flipping arms 111 work synchronously to fold the edges of multiple parts of the fabric to the upper surface of the pad, thereby improving the efficiency of folding the edges of the fabric.

[0026] It should be understood that the position of the nailing device or hand-held nail gun should be avoided from the position of the fabric turning arm 111 to prevent interference between the fabric turning arm 111 and the nailing device or hand-held nail gun.

[0027] Reference Figure 1 or Figure 2 or Figure 3In this embodiment, there are two rotary drive mechanisms 11 and two fabric-folding arms 111. The central angle between the two fabric-folding arms 111 and the center of the base plate 1 is 180°, allowing the tray 2 to rotate 180°. The two fabric-folding arms 111 can then fold all four edges of the fabric onto the pad. In another embodiment, there are two rotary drive mechanisms 11 and two fabric-folding arms 111. The central angle between the two fabric-folding arms 111 and the center of the base plate 1 is 90°, allowing the tray 2 to rotate 180°. The two fabric-folding arms 111 can also fold all four edges of the fabric onto the pad.

[0028] Reference Figure 3 or Figure 3 In some embodiments, the cushion mold further includes a telescopic rod 3 and a support plate 4. The support plate 4 is disposed in the cavity 21. The telescopic rod 3 is used to drive the support plate 4 to rise. In its natural state, the support plate 4 is flush with the tray 2. The support plate 4 and the tray 2 are used to horizontally support the fabric block, so that when the fabric block, sponge pad and pad are placed on the support plate 4 and the tray 2, the middle part of the fabric block remains flat and the middle part of the fabric block will not be concave due to the weight of the sponge pad and the pad.

[0029] When the pressure plate is pressed down, the sponge pad is compressed, the telescopic rod 3 is compressed, and the fabric support plate 4 moves down. When the sponge pad is compressed to the preset degree, the cavity 21 has shaped the sponge pad and the fabric block. Then, the rotary drive mechanism 11 drives the swing end of the fabric flipping arm 111 to swing from bottom to top and from outside to inside. The swing end of the fabric flipping arm 111 folds the edge of the fabric block to the upper surface of the pad. After the fabric flipping arm 111 folds all the edges of the fabric block to the pad, and nails all the edges of the fabric block to the pad, the desired cushion is obtained.

[0030] The lifting and lowering of the support plate 4 can prevent the sponge pad from directly pressing the fabric into the cavity 21. When the pressure plate is lowered to make the support plate 4 descend, it is beneficial to tension and shape the fabric.

[0031] There are four telescopic poles (3), see reference. Figure 5 The tray 2 has four clearance holes, and the four columns of the telescopic rod 3 pass through the four clearance holes respectively. The four columns extend into the cavity 21 and are connected to the support plate 4. The columns of the telescopic rod 3 face upward and can be raised and lowered. The telescopic rod 3 can use commonly available components on the market.

[0032] In some of these embodiments, reference is made to Figure 4The base plate 1 is equipped with a liftable positioning post 12, and the tray 2 is equipped with multiple positioning holes 22 circumferentially distributed around the rotation axis of the tray 2. The positioning post 12 is used to insert into the positioning hole 22 to position the tray 2 and prevent the tray 2 from rotating accidentally. The positioning post 12 is inserted into different positioning holes 22, so that one side of the tray 2 can be positioned facing different horizontal directions. That is, different sides of the tray 2 can be positioned facing the fabric flipping arm 111, so that the fabric flipping arm 111 can fold the edges of the fabric pieces on the corresponding different sides of the tray 2 to the upper surface of the pad.

[0033] In some of these embodiments, reference is made to Figure 4 The base plate 1 is also provided with a first lifting drive mechanism 13. The output end of the first lifting drive mechanism 13 faces upward and is connected to the positioning column 12. The first lifting drive mechanism 13 is used to drive the positioning column 12 to rise and fall. The positioning hole 22 is opened on the lower surface of the tray 2. When the first lifting drive mechanism 13 drives the positioning column 12 to rise and the positioning column 12 extends into the positioning hole 22, the positioning column 12 will block the tray 2 from rotating, thus completing the positioning of the tray 2. When the first lifting drive mechanism 13 drives the positioning column 12 to fall and the positioning column 12 exits the positioning hole 22, the tray 2 can rotate freely with the vertical direction as the rotation axis.

[0034] In this embodiment, there are two sets of first lifting drive mechanisms 13. The output ends of both sets of first lifting drive mechanisms 13 are provided with positioning pins 12. The tray 2 is provided with four sets of positioning holes 22. The two sets of positioning pins 12 respectively cooperate with two sets of positioning holes 22 in the four sets of positioning holes 22.

[0035] In some of these embodiments, reference is made to Figure 1 or Figure 2 or Figure 3 The swing end of the fabric-flipping arm 111 is connected to a clapper 1111. The movement direction of the clapper 1111 and the swing end of the fabric-flipping arm 111 are perpendicular to each other. The fabric-flipping arm 111 is provided with a clearance area to avoid the edge of the tray 2. When the rotary drive mechanism 11 drives the swing end of the fabric-flipping arm 111 to swing from bottom to top and from outside to inside, the side of the tray 2 can extend into the clearance area, so that the swing end of the fabric-flipping arm 111 and the clapper 1111 can move above the tray 2. The fabric-flipping arm 111 folds the edge of part of the fabric to the upper surface of the pad through the clapper 1111.

[0036] Understandably, the fabric-turning arm 111 is made of a plate-like material, with an avoidance area on the plate-like material, making the fabric-turning arm 111 U-shaped overall.

[0037] In some of these embodiments, exhibits Figure 2 or Figure 4The cushion mold also includes a sliding seat 5, on which a second lifting drive mechanism 51 is provided. The output end of the second lifting drive mechanism 51 is connected to the base plate 1. The second lifting drive mechanism 51 is used to drive the base plate 1 and the tray 2 to lift and lower, so as to adjust the height of the tray 2. The height of the tray 2 and the cloth, sponge pad and mat on the tray 2 are adjustable, which is suitable for nailing devices of different heights and workers of different heights to operate the nail gun at different height positions.

[0038] The sliding seat 5 can move between the loading station and the processing station, while carrying the second lifting drive mechanism 51, the base plate 1 and the pallet 2 between the loading station and the processing station. The loading station can be equipped with a cloth feeding device, a sponge pad feeding device and a pad feeding device. The feeding device, sponge pad feeding device and pad feeding device are used to feed cloth, sponge pad and pad to the pallet 2 respectively. The processing station can be equipped with a pressing device, a rotary drive device and a nailing device. The pressing device presses down the pad so that the middle of the cloth and the sponge pad enter the cavity 21. The rotary drive device drives the pallet 2 to rotate. The nailing device nails the edge of the cloth to the pad.

[0039] The sliding seat 5 is slidably connected to the guide rail, with the two ends of the guide rail respectively located at the loading station and the processing station. The sliding seat 5 is connected to a driving component, which is used to drive the sliding seat 5 to slide on the guide rail, so that the sliding seat 5 carries the second lifting drive mechanism 51, the base plate 1 and the pallet 2 between the loading station and the processing station.

[0040] Reference Figure 1 or Figure 4 There are two sliding seats 5, which are slidably connected to two guide rails. Each of the two sliding seats 5 is connected to a second lifting drive mechanism 51, and the output ends of the two second lifting drive mechanisms 51 are respectively connected to the two ends of the base plate 1.

[0041] The base plate 1 is connected to multiple drop rods, and each of the two sliding seats 5 is equipped with multiple linear bearings. The multiple drop rods cooperate with the multiple linear bearings respectively. The drop rods and linear bearings play the role of guiding the base plate 1 to rise and fall. The second lifting drive mechanism 51 plays the role of driving the base plate 1 and the tray 2 to rise and fall, thereby adjusting the height of the base plate 1 and the tray 2 so that the tray 2 can be loaded with cloth blocks, sponge pads and mats, the edges of the cloth blocks can be nailed to the mats, and the tray 2 can be unloaded with seat cushions.

[0042] Reference Figure 2 In some embodiments, a top support device 6 is also included, which is used to support / support the base plate 1. When the pressing device presses down on the pad on the base plate 1, the top support device 6 can reduce or prevent the deformation and downward movement of the base plate 1.

[0043] Reference Figures 2 to 4The top support device 6 includes a liftable top plate 61, which rises to support the bottom plate 1 and can lift the bottom plate 1. Specifically, the top plate 61 is located between two sliding seats 5, with the top plate 61 facing the middle of the bottom plate 1, and the rising top plate 61 can support the middle of the bottom plate 1.

[0044] In some embodiments, the top support device 6 further includes a guide seat 62 and a linear drive mechanism 63. The top plate 61 is slidably mounted on the guide seat 62, which guides the top plate 61 to rise and fall. The output end of the linear drive mechanism 63 is connected to a wedge block 631, the inclined surface of which abuts against the lower end of the top plate 61, and the inclined surface is used to drive the top plate 61 to rise. Initially, the top plate 61 is in a low position to avoid interference with the movement of the bottom plate 1. When the bottom plate 1 moves above the top plate 61, the second lifting drive mechanism 51 drives the bottom plate 1 to rise and fall, so that the bottom plate 1 is at a suitable working height. Then, the linear drive mechanism 63 drives the wedge block 631 to move, so that the inclined surface of the wedge block 631 lifts the top plate 61, and the top plate 61 abuts against the lower surface of the bottom plate 1, thereby supporting the bottom plate 1.

[0045] In this embodiment, the guide seat 62 is annular, and the axial direction of the central hole of the guide seat 62 is parallel to the vertical direction. Two guide holes are opened on the side wall of the guide seat 62, and both guide holes are connected to the central hole of the guide seat 62. There are two linear drive mechanisms 63, and the output ends of the two linear drive mechanisms 63 are connected to wedge blocks 631. The length directions of the wedge blocks 631 are parallel to each other, and the two wedge blocks 631 are on the same straight line. The two wedge blocks 631 extend into the central hole of the guide seat 62 through the two guide holes respectively. The inclined surface of the wedge block 631 is inclined upward. The lower surface of the top plate 61 is provided with a guide post that cooperates with the central hole of the guide seat 62. The lower surface of the guide post can abut against the inclined surface of the two wedge blocks 631.

[0046] The linear drive mechanism 63 is a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The linear drive mechanism 63 is horizontally arranged, which can reduce the height of the top support device 6.

[0047] In another embodiment, the linear drive mechanism 63 and the wedge block 631 can be replaced by a third lifting drive mechanism. The output end of the third lifting drive mechanism is connected to the top plate 61, and the third lifting drive mechanism is used to drive the top plate 61 to rise and fall.

[0048] Exhibitor Figure 3 or Figure 4 In some embodiments, the tray 2 is connected to the middle of the base plate 1 via a rotating assembly 7, which allows the tray 2 to rotate on the base plate 1 about the vertical axis of rotation. The rotating assembly 7 can reduce the resistance encountered by the tray 2 when it rotates.

[0049] It is understood that the rotating assembly 7 includes a bearing seat located in the middle of the base plate 1, a bearing seat provided on the bearing seat and a column seat connected to the middle of the tray 2. The column seat is connected to the bearing, and the column seat and the tray 2 can rotate on the base plate 1 with the vertical direction as the rotation axis.

[0050] Reference Figure 5 In some embodiments, the tray 2 adopts a split structure, including a connecting plate 23 and a limiting plate 24 connected together. The connecting plate 23 is rotatably connected to the base plate 1, and the limiting plate 24 is disposed on the connecting plate 23. A through hole is formed on the limiting plate 24, and the inner wall of the through hole and the upper surface of the connecting plate 23 form a cavity 21. The processing of the through hole is relatively simple and convenient. After processing the through hole on the limiting plate 24, the limiting plate 24 is connected to the connecting plate 23 to obtain the desired tray 2.

[0051] Understandably, the middle part of the connecting plate 23 is connected to the column base. It should be noted that four clearance holes penetrate the connecting plate 23, and all four clearance holes are connected to the through hole. The four columns of the telescopic rod 3 are respectively inserted through the four clearance holes, and the four columns extend into the through hole and are connected to the support plate 4.

[0052] Of course, the tray 2 can be a one-piece molded structure, and the required tray 2 can be obtained by directly machining the cavity 21 on the entire plate. The through hole is a stepped hole with a larger top and a smaller bottom, and the inner wall of the lower end of the through hole is arc-shaped. The inner wall of the lower end of the through hole shapes the cloth and sponge pad.

[0053] The first lifting drive mechanism 13, the second lifting drive mechanism 51, and the third lifting drive mechanism can all be pneumatic cylinders, hydraulic cylinders, or electric cylinders. The rotary drive mechanism 11 is a motor or a rotary cylinder. The output end of the rotary drive mechanism 11 rotates with the horizontal direction as its central axis of rotation.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
