DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0031] Reference Figures 1 to 11 The edge-matching mechanism includes a bracket 1, a slide rail 2 arranged along the front-back direction is provided on the bracket 1, a slider 3 is provided on the slide rail 2, and the slider 3 is slidably connected to the slide rail 2. A first driving device 4 is provided on the bracket 1, and the first driving device 4 drives the slider 3 to reciprocate along the length direction of the slide rail 2. A swing arm 9 is connected to the slider 3 through a first rotating shaft 6. A second driving device is provided on the slider 3, and the second driving device drives the swing arm 9 to swing around the first rotating shaft 6, and the swing arm 9 is connected to a push plate 18.

[0032] In the prior art, when a traditional edge taping machine processes a mattress, the mattress needs to be aligned after edge taping. The above-mentioned alignment means that the edge of the mattress is parallel to the conveying direction of the conveyor belt to ensure that the edge of the mattress is straight. For example, the Chinese patent publication "An Automatic Turning Mattress Edge Taping Machine", whose announcement number is CN206127702U, still requires manual pushing of the mattress during processing to make the edge of the mattress to be taped parallel to the conveying direction of the conveyor belt, and align the mattress with the processing station of the edge taping machine for sewing.

[0033] From the above, it can be concluded that the slider 3 is connected to the swing arm 9 through the first rotation, thereby forming a fulcrum at the first rotating shaft 6, and the swing arm 9 is driven to swing around the fulcrum under the second driving device, so that the swing arm 9 forms a lever structure. The user can determine the height of the push plate 18 by controlling the swing position of the swing arm 9, which is suitable for mattresses of various thicknesses and is flexible to use. The first driving device 4 drives the slider 3 to move along the length direction of the slide rail 2, thereby driving the push plate 18 to move back and forth along the length direction of the slide rail 2. The user can use the push plate 18 to push the side of the mattress so that the side of the mattress is flush with the push plate 18 during the pushing process.

[0034] Preferably, during use, the user can arrange the conveying direction of the push plate 18 and the length direction of the push plate 18 to be parallel to each other.

[0035] In addition, the size of the two torques on both sides of the fulcrum can be adjusted according to actual conditions, thereby adjusting the size of the arc of the swing of the swing arm 9 and the size of the torque when the swing arm 9 swings. The user can also use the second drive device to drive the swing arm 9 through the lever structure to drive the mattress to move. The user can control the movement of the push plate 18 through the first drive device 4 and / or the second drive device to drive the mattress to move according to actual conditions. For example, for some mattresses with relatively large mass, the user can form a labor-saving lever structure by adjusting the size of the force arms on both sides of the fulcrum.

[0036] In some embodiments, the first driving device 4 includes a motor 41, a synchronous belt 42, and a pulley 43. At least two pulleys 43 are provided and arranged along the length direction of the slide rail 2. The synchronous belt 42 is provided beside the slide rail 2. The synchronous belt 42 is connected to the pulley 43 in a transmission manner. The motor 41 is provided on the bracket 1. The motor 41 is connected to one pulley 43 in a driving manner. The synchronous belt 42 is fixedly connected to the slider 3 and drives the slider 3 to slide along the length of the slide rail 2. The structure is simple and convenient to set. When in use, the motor 41 drives the pulley 43 to rotate, and then drives the slider 3 to move through the synchronous belt 42. Therefore, optionally, for the motor 41, the user can use a servo motor 41, which is convenient for the user to control the movement stroke of the slider 3. Then, when pushing materials for mattresses of different sizes, the user can determine the pushing distance accordingly. The use is more flexible and can be adapted to mattresses of various sizes.

[0037] In some embodiments, the second driving device includes a first cylinder 5, a second rotating shaft 7 is provided on the slider 3, the second rotating shaft 7 is rotatably connected to the first cylinder 5, a third rotating shaft 8 is provided on the swing arm 9, the two ends of the first cylinder 5 are respectively connected to the second rotating shaft 7 and the third rotating shaft 8, and the first cylinder 5 drives the second rotating shaft 7 and the third rotating shaft 8 to move toward each other or move away from each other. The structure is simple and convenient to set up. Optionally, the movable part of the first cylinder 5 is connected to the swing arm 9 through the third rotating shaft 8, and the fixed part of the first cylinder 5 is connected to the slider 3 through the second rotating shaft 7, or the movable part of the first cylinder 5 is connected to the swing arm 9 through the second rotating shaft 7, and the fixed part of the first cylinder 5 is connected to the slider 3 through the third rotating shaft 8.

[0038] The second rotating shaft 7 and the third rotating shaft 8 are brought closer to or farther away from each other through the telescopic movement of the first cylinder 5 . During the telescopic movement of the first cylinder 5 , the first cylinder 5 drives the swing arm 9 to swing around the first rotating shaft 6 .

[0039] In some embodiments, two slide rails 2 are provided, each of the slide rails 2 is fixedly connected to the bracket 1, each of the slide rails 2 is slidably fitted with a slider 3, each slider 3 is provided with a first rotating shaft 6, each first rotating shaft 6 is connected to a swing arm 9, the push plate 18 is provided between the two swing arms 9, and the two swing arms 9 are respectively connected to the push plates 18.

[0040] In actual use, two slide rails 2 are set, and a slider 3 is correspondingly slidably matched on each slide rail 2. At the same time, a first rotating shaft 6 is set on each slider 3. Each first rotating shaft 6 is rotatably connected to a swing arm 9. Each swing arm 9 is connected to a first cylinder 5 through a third rotating shaft 8. A push plate 18 is provided between the two swing arms 9. Through the setting of this structure, the structure is more stable, and the two swing arms 9 are symmetrically fixedly connected to the push plate 18.

[0041] In some embodiments, a plurality of pulleys 43 are arranged along the length direction of the slide rail 2 on the side of each slide rail 2 to form a pulley 43 group, and each pulley 43 group is connected to a synchronous belt 42; in two pulley 43 groups, any pulley 43 in one pulley 43 group is connected to any pulley 43 in another pulley 43 group through a transmission shaft 10. In this embodiment, the pulleys 43 are arranged in the front-to-back direction, and the axis of the pulley 43 extends in the left-to-right direction.

[0042] In some embodiments, a push cylinder 21 is provided on the swing arm 9, and the push cylinder 21 is connected to the push plate 18, and the push cylinder 21 drives the push plate 18 to reciprocate forward and backward. With this structural setting, when in use, the user can further drive the push plate 18 to push the mattress through the push cylinder 21, and the pushing range of the mattress is more flexible.

[0043] In some embodiments, at least one push cylinder 21 is provided on each swing arm 9. For example, when there are two swing arms 9, one push cylinder 21 is provided on each swing arm 9, and the push plate 18 connects all the push cylinders 21, that is, all the push cylinders 21 drive the same push plate 18 at the same time.

[0044] Furthermore, a bushing 22 is provided on the swing arm 9 , and a guide rod 20 is slidably fitted in the bushing 22 . The guide rod 20 is fixedly connected to the push plate 18 , and the length direction of the guide rod 20 is parallel to each other along the pushing direction of the push cylinder 21 .

[0045] Furthermore, the number of bushings 22 and push cylinders 21 is set one by one, and a bushing 22 is set on the side of each cylinder. Similarly, each bushing 22 slides with a guide rod 20, and each guide rod 20 remains inserted into the bushing 22, and each guide rod 20 is fixedly connected to the push plate 18.

[0046] Of course, in some other embodiments, the user may also directly fix the push plate 18 to the swing arm 9 .

[0047] The present invention further provides an edge-cutting machine, comprising a frame 12, the bracket 1 being the frame 12, and also comprising an edge-cutting mechanism of any combination of the above technical solutions, and a working platform 11 arranged on the frame 12, wherein the pusher plate 18 is arranged above the working platform 11. The working platform 11 is used to place a mattress to be edge-cut, and the pusher plate 18 is used to push the mattress on the working platform 11.

[0048] The present embodiment also includes an edge alignment mechanism of any combination of the above technical solutions. Since the drawings in the specification and the above text description have already provided relevant explanations for the edge alignment mechanism, the description will not be expanded here.

[0049] In some embodiments, the working platform 11 includes a first conveyor belt device 111 and a second conveyor belt device 112 arranged in sequence along the left-right direction, the first conveyor belt device 111 and the second conveyor belt device 112 are respectively arranged on the frame 12, the first conveyor belt device 111 and the second conveyor belt device 112 are provided with a gap extending along the front-to-back direction, the width of the swing arm 9 is smaller than the gap, and the swing arm 9 reciprocates in the front-to-back direction in the gap.

[0050] In some embodiments, a swing arm 9 is provided on the side of the first conveyor belt device 111 or the second conveyor belt device 112 that is away from each other, and the swing arm 9 is called an outer arm. At the same time, a swing arm 9 is provided in the gap between the first conveyor belt device 111 and the second conveyor belt device 112, and the swing arm 9 is called an inner arm. The inner arm can swing back and forth in the gap, and a push plate 18 is provided between the inner arm and the outer arm. The inner arm and the outer wall are respectively fixedly connected to the push plate 18. At the same time, correspondingly, two slide rails 2 are provided, each of which is fixedly connected to the bracket 1, and the bracket 1 can be fixedly connected to the frame 12. Each of the slide rails 2 is slidably matched with a slider 3, and each slider 3 is provided with a first rotating shaft 6. The two first rotating shafts 6 are correspondingly connected to an outer arm or an inner arm, and the structure is compact and stable.

[0051] In some embodiments, a support frame 13 is provided in the gap, and the support frame 13 is fixedly connected to the frame 12, and the support frame 13 is used to support the mattress.

[0052] When in use, after the edge of the top surface of the mattress is processed, the edge of the bottom surface of the mattress needs to be processed, and the mattress often needs to be turned over. For example, the Chinese patent publication "An Automatic Turning Mattress Edge Machine" mentioned above, with the publication number CN206127702U, respectively hinges the first turning rod and the second turning rod on the first conveyor belt device 111 and the second conveyor belt device 112, and clamps the mattress to make it stand up by applying external force to the first turning rod and the second turning rod, and then turns the mattress to the side, so as to achieve the turning of the mattress. However, in this embodiment, since there is a gap between the first conveyor belt device 111 and the second conveyor belt device 112, some relatively thin mattresses may be embedded in the gap when standing up, resulting in the inability to turn the mattress over.

[0053] In this embodiment, the mattress can be supported by providing a support frame 13 to prevent the entire mattress from being embedded in the gap.

[0054] Although the support frame 13 is used to support the mattress in the above embodiment, for some wider mattresses, the support frame 13 fails to support the center of the mattress, and the mattress may tip over and be embedded in the gap.

[0055] To this end, in some embodiments, a fixing frame 14 is provided on the first conveyor belt device 111 and / or the second conveyor belt device 112, a track 15 is provided on the fixing frame 14, a connecting plate 16 is provided on the track 15, and the connecting plate 16 slidably cooperates with the track 15, and a spring 19 is provided on the fixing frame 14 along the left and right directions, one end of the spring 19 is connected to the fixing frame 14, and the other end of the spring 19 is connected to the connecting plate 16, and the movement stroke of the connecting plate 16 intersects with the gap, and the front side and rear side of the connecting plate 16 close to the gap are provided with rounded corners 161, and the rounded corners 161 intersect with the movement trajectory of the swing arm 9.

[0056] During use, when the swing arm 9 swings to abut the fillet 161, under the action of the force applied by the swing arm 9 to the fillet 161, the connecting plate 16 overcomes the elastic force of the spring 19 and tends to move along the track 15 in the direction away from the gap. When the swing arm 9 moves away from the fillet 161, under the action of the elastic force of the spring 19, the connecting plate 16 is reset. Through the setting of this structure, the swing arm 9 can move smoothly in the gap. On the one hand, it can push the mattress flexibly and push the mattress to more positions. Moreover, its structure is compact and occupies relatively less space. On the other hand, after the swing arm 9 is separated from the fillet 161, the pushing plate 18 can support the mattress to prevent some mattresses with a thickness less than or equal to the gap width from being embedded in the gap during the flipping process.

[0057] In some embodiments, a baffle 17 is provided on the frame 12, and the baffle 17 is directly opposite to the push plate 18, and the baffle 17 is parallel to the push plate 18. The structure is simple and convenient to set. Through the setting of the structure, the user can push the front side of the mattress through the push plate 18 until the rear side of the mattress abuts against the baffle 17, thereby realizing the rapid positioning of the mattress. Preferably, the position where the baffle 17 is set is flush with the position of the sewing machine head that performs hemming processing on the edge of the mattress.

[0058] In some embodiments, the pushing direction of the pushing cylinder 21 is along the direction from the pushing plate 18 to the baffle 17. Similarly, the axial direction of the bushing 22 and the guide rod 20 extends along the direction from the pushing plate 18 to the baffle 17, so that in the process of pushing the mattress by using the pushing cylinder 21, the mattress can be pushed from the pushing plate 18 to the baffle 17.

[0059] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
