Description

Technical Field

[0001] This invention relates to the field of mattress adhesive stitching technology, specifically to a self-adhesive stitching mechanism for mattress production. Background Technology

[0002] In the current mattress production process, the bonding of the foam fabric and the mattress core mainly relies on manual operation. After bonding, the mattress is conveyed to the sewing machine for automatic sewing. In actual operation, the workers first place the semi-finished mattress to be processed on a fixed support frame or conveyor device. Then, the composite foam fabric (usually a composite fabric made of a surface knitted fabric and a bottom polyurethane foam, which is soft, porous and breathable) is laid flat on the mattress surface. Since the glue used is mostly fast-drying and curing type, in order to avoid the glue from drying out, the workers usually lift half of the flat fabric by hand to expose one half of the mattress. Then, they quickly spray the fabric with a spray gun. After spraying, the workers quickly put down the lifted half of the fabric and then lift the other half of the fabric for spraying and bonding. To facilitate rapid fabric finishing, most production workshops currently employ at least two workers at each workstation for this process: one worker lifts the fabric, while the other applies the adhesive. However, even with two workers collaborating, the rapid drying of the adhesive necessitates close coordination in the "lifting fabric, applying adhesive, and repositioning" actions. This often results in pauses due to waiting or temporary alignment, further compressing the work cycle. This over-reliance on manual labor and the presence of numerous waiting gaps negatively impacts the efficiency of mattress adhesive application and consumes valuable workshop resources. Therefore, we propose a self-adhesive sewing mechanism for mattress production. Summary of the Invention

[0003] The purpose of this invention is to provide a self-adhesive sewing mechanism for mattress production, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a self-adhesive sewing mechanism for mattress production, comprising a mattress conveying mechanism for conveying the mattress body, a self-sewing mechanism, and a workbench fixed to the ground. The workbench is disposed on one side of the mattress conveying mechanism, and multiple adjustable limiting plates are installed on the workbench. Multiple pieces of fabric are stacked on the workbench, and the multiple adjustable limiting plates limit the stacking of fabric. The invention also includes a fixed frame disposed above the mattress conveying mechanism and the workbench. The fixed frame is fixedly connected to the workbench and the ground through a support rod frame. The fixed frame is provided with a picking-up part for transferring the fabric. It also includes support plates on both sides of the mattress conveying mechanism, one of which is fixedly connected to the support rod frame, and the other is fixedly installed on the workbench. A fixed shaft is provided above the mattress conveying mechanism, and multiple glue guns are fixedly installed on the fixed shaft. The support plate is provided with a drive unit for driving the fixed shaft to move in an directional manner.

[0005] Preferably, the drive unit is set on the belt conveyor mechanism on the two support plates. The pulleys at both ends of the belt conveyor mechanism are fixedly connected by connecting shafts. A servo motor is fixedly installed on the outer wall of one of the support plates, and the output end of the servo motor is fixedly connected to the end of one of the connecting shafts. A bearing plate is fixedly installed on both belt conveyors, and the fixed shaft is fixedly connected to the bearing plate.

[0006] Preferably, the pickup unit includes a movable plate frame mounted on a fixed frame. The movable plate frame has a slot, and a square frame is slidably mounted inside the slot. A first demagnetizing shaft is slidably mounted on the square frame, and a second demagnetizing shaft is slidably mounted on the movable plate frame. A first needle-type suction cup is rotatably mounted at the bottom end of the first demagnetizing shaft, and a second needle-type suction cup is rotatably mounted at the bottom end of the second demagnetizing shaft.

[0007] Preferably, a magnetic plate frame is fixedly installed on both the first and second demagnetizing shafts, and an annular electromagnet is fixedly installed on the lower surface of the movable plate frame and the lower surface of the square frame. The annular electromagnet is energized to generate a repulsive force on the magnetic plate frame. A spring is connected between the top end of the first demagnetizing shaft and the upper surface of the square frame, and between the second demagnetizing shaft and the upper surface of the movable plate frame.

[0008] Preferably, limit sliders are fixedly installed at both ends of the movable plate frame, and limit grooves are provided on the inner walls of both sides of the fixed frame. The limit sliders slide within the limit grooves. A hydraulic cylinder is fixedly installed at one end of the fixed frame, and the output end of the hydraulic cylinder is fixedly connected to the end of the movable plate frame.

[0009] Preferably, a motor body is fixedly installed on one side of the fixed frame, and a lead screw body is rotatably installed inside the fixed frame. The output end of the motor body is fixedly connected to the end of the lead screw body. An action frame is installed on the lead screw body, and the action frame is slidably connected to the inner wall of the fixed frame.

[0010] Preferably, the action frame is located on the movement trajectory of the square frame, and a fixed plate frame is also fixedly installed on the magnetic plate frame on the demagnetizing shaft, and a telescopic shaft is rotatably installed on the fixed plate frame.

[0011] Preferably, the fixed frame is provided with a guide groove at the end away from the hydraulic cylinder. The guide groove includes a sliding area, an inclined area and a reset area, and the telescopic shaft slides within the guide groove.

[0012] Preferably, a guide panel is fixedly installed at the intersection of the sliding area and the inclined area, and the guide panel on the side of the sliding area is an inclined surface, and the guide panel on the side of the inclined area is a right-angled surface.

[0013] Preferably, guide plate frames are fixedly installed on the inner sidewalls of both support plates, and the bottom of the bearing plate slides at the upper limit of the guide plate frames.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves stable stacking and precise material positioning of multi-layer fabrics through the coordinated limiting effect of the adjustable limiting plate on the worktable and the side wall of one of the plates. At the same time, the energized annular electromagnet generates a repulsive force on the magnetic plate frame to drive the needle suction cups one and two to descend and adsorb the fabric. After the power is cut off, the spring part resets upward to complete the automatic picking up and lifting of the fabric, effectively replacing the traditional manual handling of fabric. This improves the efficiency of fabric pretreatment and preparation while ensuring the consistency of the gripping benchmark for each piece of fabric. 2. This invention utilizes a motor to drive a lead screw, which in turn moves the frame. This causes the square frame to slide laterally within the slot, gradually bringing the demagnetizing shaft and needle-type suction cup one closer to the needle-type suction cup two. Simultaneously, a telescopic shaft mounted on the fixed plate slides along the inclined area of ​​the guide groove, allowing one end of the fabric to be first attached and positioned on the mattress body while the other end is automatically lifted. Subsequently, the servo motor drives the bearing plate on the belt conveyor mechanism to slide directionally along the guide plate via the connecting shaft, causing the glue gun on the fixed shaft to perform glue spraying. The glue spraying action is synchronized with the fabric laying action, improving the efficiency of the glue application process. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-11This invention provides a technical solution: a self-adhesive sewing mechanism for mattress production, comprising a mattress conveying mechanism 1 for conveying the mattress body 4, a self-sewing mechanism 2 for automatically binding and sewing the mattress after adhesive application, and a workbench 3 fixed on the floor of the workshop. The workbench 3 is located adjacent to the mattress conveying mechanism 1, and multiple adjustable limiting plates 31 are installed on the surface of the workbench 3. These adjustable limiting plates 31 can be adjusted in position according to the actual size of the fabric 5 placed, thereby limiting the area where the fabric 5 is placed. A fixed frame 6 is arranged above the mattress conveying mechanism 1 and the workbench 3. In order to ensure that the fixed frame 6 can stably span across the two working areas, the outer side of the fixed frame 6 is connected to the workbench 3 and the ground support respectively through support rods 61. During operation, the mattress body 4 is conveyed on the mattress conveying mechanism 1, and the fixed frame 6 is located above the conveying path of the mattress body 4. Support plates 8 are provided on both sides of the mattress conveying mechanism 1. One support plate 8 is fixedly connected to the support rod frame 61, and the other support plate 8 is fixedly installed on the worktable 3. The outer side of the support plate 8 fixedly installed on the worktable 3 serves as the initial positioning and limiting surface of the fabric 5 on the worktable 3. When the fabric 5 is placed on the worktable 3, the fabric 5 first contacts the side of the support plate 8 and is restricted. The operator then adjusts the adjustable limiting plates 31 in other positions to limit the fabric 5.

[0019] Combined with appendix Figure 2 and attached Figure 6 As shown, a pickup unit 7 for automated transfer of fabric 5 is provided on the fixed frame 6. The pickup unit 7 includes a movable plate frame 71 on the fixed frame 6. A slot 72 is provided on the movable plate frame 71. A square frame 73 is slidably installed inside the slot 72. A demagnetizing shaft 74 is slidably installed on the square frame 73. A demagnetizing shaft 75 is slidably installed on the movable plate frame 71. A needle suction cup 741 is rotatably installed at the bottom end of the demagnetizing shaft 74. A needle suction cup 751 is rotatably installed at the bottom end of the demagnetizing shaft 75. Both the needle suction cup 741 and the needle suction cup 751 are designed with at least two suction parts at their bottom ends. When these suction parts pick up the fabric 5, they accurately correspond to the edge positions on both sides of the fabric 5. Since the edge position of the fabric 5 is usually a relatively compact textile edge area, suction and extraction from this position can effectively avoid tearing or local stretching deformation of the fabric 5 during the suction and transfer process. A ring electromagnet 77 is fixedly installed on the lower surface of the movable plate frame 71 and the lower surface of the square frame 73. Magnetic plates 76 are fixedly installed on both the first demagnetizing shaft 74 and the second demagnetizing shaft 75. When the ring electromagnet 77 is energized, it generates a repulsive force on the magnetic plates 76 directly below it, thereby pushing the first demagnetizing shaft 74 and the second demagnetizing shaft 75 downwards. The inner wall of the ring electromagnet 77 does not contact the outer wall of the demagnetizing shaft, leaving a slight isolation gap between them to ensure physical smoothness during up-and-down sliding. A magnetic plate frame 76 is fixedly installed between the top of the first demagnetizing shaft 74 and the upper surface of the square frame 73, and between the top of the second demagnetizing shaft 74 and the upper surface of the square frame 73. A spring 78 is connected between the top end and the upper surface of the movable plate frame 71. When the annular electromagnet 77 is de-energized, the spring 78, which is in a compressed state, provides an upward restoring force. Limiting sliders 79 are fixedly installed at both ends of the movable plate frame 71. Limiting grooves 67 are opened on both sides of the inner wall of the fixed frame 6. The limiting sliders 79 slide horizontally within the limiting grooves 67. A hydraulic cylinder 62 is fixedly installed at one end of the fixed frame 6, and the output end of the hydraulic cylinder 62 is fixedly connected to the end of the movable plate frame 71. Activating the hydraulic cylinder 62 can push the movable plate frame 71 to move back and forth on the fixed frame 6.

[0020] Combined with appendix Figure 7 As shown, a motor body 63 is fixedly installed on one side of the fixed frame 6. A lead screw body 64 is rotatably installed inside the fixed frame 6, and the output end of the motor body 63 is fixedly connected to the end of the lead screw body 64. An action frame 65 is fitted onto the lead screw body 64. Because the action frame 65 slides against the inner wall of the fixed frame 6, when the motor body 63 drives the lead screw body 64 to rotate in both directions, the action frame 65 can achieve smooth lateral movement in the reciprocating direction inside the fixed frame 6. (See attached diagram.) Figure 6 As shown, the action frame 65 is located on the movement trajectory of the square frame 73. Therefore, when the square frame 73 is located inside the action frame 65, the action frame 65 can push the square frame 73 to perform synchronous limiting sliding within the slot 72 during the movement process.

[0021] Furthermore, a guide groove 66 is provided on the inner wall of the end of the fixed frame 6 away from the hydraulic cylinder 62. The guide groove 66 is composed of a sliding area 661, an inclined area 662 and a reset area 663. A guide panel 664 is fixedly installed at the intersection of the sliding area 661 and the inclined area 662. The side of the guide panel 664 facing the sliding area 661 is an inclined surface, while the side of the guide panel 664 facing the inclined area 662 is a right-angled surface.

[0022] Combined with appendix Figure 5As shown, a fixed plate frame 761 is also fixedly installed on the magnetic plate frame 76 on the demagnetizing shaft 74, and a telescopic shaft 762 is rotatably installed on the fixed plate frame 761. The guide groove 66 is located on the movement trajectory of the telescopic shaft 762. That is, when the square frame 73 is located inside the action frame 65, the telescopic shaft 762 is located at the initial end of the sliding area 661 of the guide groove 66. The initial end of the sliding area 661 refers to the intersection of the sliding area 661 and the reset area 663.

[0023] A fixed shaft 9 is provided above the mattress conveying mechanism 1, and multiple glue spray guns 91 are fixedly mounted on the fixed shaft 9. A drive unit 10 for driving the directional movement of the fixed shaft 9 is provided on the support plate 8; combined with the attached... Figure 10 As shown, the drive unit 10 includes belt conveyor mechanisms 101 respectively mounted on two side support plates 8. The pulleys at both ends of the belt conveyor mechanisms 101 are fixedly connected via connecting shafts 102. A servo motor 103 is fixedly mounted on the outer wall of one side support plate 8. The output end of the servo motor 103 is fixedly connected to the end of one of the connecting shafts 102. When the servo motor 103 starts, its power can synchronously drive the belt conveyor mechanism 101 to perform directional movement. Bearing plates 104 are correspondingly mounted on both belt conveyor mechanisms 101. Guide plate frames 105 are fixedly mounted on the inner walls of both support plates 8. The bottom of the bearing plate 104 slides at the upper limit of the guide plate frame 105. The belt conveyor mechanisms 101 and the guide plate frames 105 are both components of the drive unit 10. The guide plate frames 105 are used to limit and guide the bearing plates 104. The fixed shaft 9 is fixedly connected to the bearing plates 104 on both sides. The adhesive pipe of the glue spray gun 91 can pass through the interior of the fixed shaft 9. The nozzles of multiple glue spray guns 91 are uniformly downward and evenly arranged along the width direction of the mattress body 4. Driven by the bearing plates 104 and the fixed shaft 9, the glue spray guns 91 can move horizontally along the longitudinal direction of the mattress body 4 and spray adhesive. During the operation, the start, stop or position control of each major moving part can be logically controlled by the set electronic control element. For example, the feedback of the conveying position of the mattress body 4 on the mattress conveying mechanism 1 and the start and stop signals, the pushing and pulling timing of the hydraulic cylinder 62, and the positioning of the transfer path of the pickup part 7 are all assisted by the external electronic control box or central controller to ensure the stability of the process rhythm. Since the design of this electronic control element is existing technology, the present invention does not describe it in detail.

[0024] Combined with appendix Figure 1As shown, after the mattress body 4 is coated with adhesive and laid out, it needs to be transferred to the self-sewing mechanism 2. During this transfer process, a flattening process can be added above the mattress conveying mechanism 1. That is, a flattening roller is set up. When the mattress body 4, after being coated with adhesive and laid out, passes under the flattening roller, the arc-shaped outer wall of the flattening roller will apply a uniform downward pressure to the upper surface of the mattress body 4. This allows the fabric 5 that has just been laid out to be completely flattened and adhered to the mattress body 4. The fiber texture inside the fabric 5 is smoothed out, thereby eliminating the small wrinkles or bulges that may be generated during the laying process, and ensuring the straightness of the edges during subsequent edge sewing. Then the mattress body 4 is smoothly fed into the working port of the self-sewing mechanism 2, and the self-sewing mechanism 2 completes the overall edge locking and sewing of the mattress. Since the flattening roller design is a conventional design for those skilled in the art, the present invention does not describe it in detail.

[0025] Specifically, the mattress conveying mechanism 1 transports the mattress body 4, which has been filled with springs and foam support layers, to the area directly below the fixed frame 6. At this time, multiple glue spray guns 91 fixed on the fixed shaft 9 are positioned on one side edge above the mattress body 4, with the nozzles of the glue spray guns 91 close to but not in contact with the upper surface of the mattress body 4. Subsequently, the annular electromagnets 77 on the lower surface of the movable plate frame 71 and the lower surface of the square frame 73 are simultaneously energized. After the annular electromagnets 77 are energized, they generate a repulsive force on the magnetic plate frame 76 below them, thereby pushing the demagnetizing shaft 1 74 and demagnetizing shaft 2 75 to move downwards simultaneously. During the downward movement, the spring parts 78 corresponding to the demagnetizing shaft 1 74 and demagnetizing shaft 2 75 are in a compressed state, and the needle suction cups 1 741 and 2 751 also descend synchronously. When the needle suction cups 1 741 and 2 751 descend to the single surface... At the two edges of the material 5, namely needle suction cup 1 741 and needle suction cup 2 751, the material 5 comes into contact with the material. After the suction cups are energized and attracted, the annular electromagnet 77 is de-energized. The spring part 78, which is in a compressed state, returns to its original shape and pushes the demagnetizing shaft 1 74 and demagnetizing shaft 2 75 upward. The needle suction cup 1 741 and needle suction cup 2 751 grab the material 5 and lift it to reset. Then the hydraulic cylinder 62 is activated. The output end of the hydraulic cylinder 62 pushes the moving plate frame 71. The limiting sliders 79 at both ends of the moving plate frame 71 slide in the limiting groove 67, so that the material 5 moves to the top of the mattress body 4. At the same time as the moving plate frame 71 moves, the square frame 73 is also pushed into the interior of the action frame 65. At this time, the telescopic shaft 762 on the fixed plate frame 761 will also move to the initial end of the intersection of the sliding area 661 and the reset area 663 in the guide groove 66. When needle-type suction cup 1 741 and needle-type suction cup 2 751 reach directly above the mattress body 4 and the telescopic shaft 762 is at the initial end of the sliding area 661, the motor body 63 starts, and the lead screw body 64 rotates in the forward direction, thereby driving the action frame 65 to move towards the needle-type suction cup 2 751. The movement of the action frame 65 will simultaneously push the square frame 73 to slide in the slot 72. The square frame 73 drives the demagnetizing shaft 1 74 and needle-type suction cup 1 741 to move horizontally towards the needle-type suction cup 2 751. During this process, the telescopic shaft 762 moves from the intersection of the sliding area 661 and the reset area 663 to the inclined area 662. That is, the telescopic shaft 762 is guided by the inclined surface of the guide panel 664 into the inclined area 662. Then, the annular electromagnet 77 on the moving plate frame 71 is energized, generating a repulsive force against the magnetic plate frame 76 on the demagnetizing shaft 2 75, pushing the demagnetizing shaft 2 75 and needle-type suction cup 2 751 to move downwards individually, combined with the attached Figure 4 As shown, the appendix Figure 4 The downward arrow indicates that the needle suction cup 751 presses down on one end of the fabric 5, causing the fabric 5 to adhere downwards to the surface of the mattress body 4. This allows one end of the fabric 5 to be pressed firmly against the upper surface of the mattress body 4 by the needle suction cup 751, forming a stable initial laying reference. As the needle suction cup 741 continues to approach the needle suction cup 751 horizontally, the telescopic shaft 762 is forced to slide diagonally upwards within the inclined area 662. Since one end of the fabric 5 is fixed by the needle suction cup 751, and the other end is continuously pulled by the needle suction cup 741, the fabric 5 is gradually lifted along this pulling direction to form a "film" shape. At this point, the lifted area completely exposes the previously covered glue gun 91. Figure 8 As shown, the appendix Figure 4 The upward-sloping arrow indicates that the telescopic shaft 762 is forced to slide upwards within the inclined area 662, thereby causing the needle suction cup 741 to perform a corresponding directional movement; the servo motor 103 starts, and the output end drives the belt conveyor mechanism 101 through the connecting shaft 102 to drive the bearing plates 104 on both sides to slide directionally on the guide plate frame 105. The bearing plate 104 drives the fixed shaft 9 and the glue gun 91 to move at a constant speed from one end of the mattress body 4 to the other end. During the movement of the glue gun 91, glue is evenly sprayed onto the upper surface of the mattress body 4. While the servo motor 103 starts, the motor body 63 rotates in reverse, and the lead screw body 64 drives the action frame 65 and the square frame 73 to move backward. At this time, the telescopic shaft 762 will slide downward along the inclined area 662. During this process, the annular electromagnet 77 on the lower surface of the moving plate frame 71 is kept energized, applying a downward repulsive force to the needle suction cup 741. Combined with the inclined downward trajectory of the telescopic shaft 762, the needle suction cup 741 moves horizontally in the backward direction and also tends to descend obliquely. Under the traction of the needle suction cup 741, the fabric 5 is laid flat on the mattress body 4 with the glue sprayed on. During the moving and laying process, the glue spray gun 91 is always located in the uncovered exposed area between the fabric 5 and the mattress body 4, and the normal working trajectory of the glue spray gun 91 always avoids any physical contact with the fabric 5 that is gradually attached to the mattress body 4, thus avoiding the problem of glue contaminating the surface of the fabric 5 or the nozzle scratching the fabric 5. When the telescopic shaft 762 descends along the inclined area 662 to the endpoint where it intersects with the reset area 663, the needle suction cup 741 has shifted and descended to its lowest position. The other end of the fabric 5 is also completely and smoothly laid on the mattress body 4, which has been sprayed with adhesive. Subsequently, the annular electromagnets 77 on the lower surface of the moving plate frame 71 and the lower surface of the square frame 73 are de-energized, and the spring part 78 resets, causing the demagnetizing shaft 74 and the demagnetizing shaft 75 to return to their original positions. The telescopic shaft 762, under the action of avoiding the gap, returns to the initial end of the sliding area 661 along the trajectory of the reset area 663. Figure 8 As shown, the arrows within the sliding area 661 indicate that the telescopic shaft 762 slides from the intersection of the sliding area 661 and the reset area 663 towards the inclined area 662; the arrows within the inclined area 662 indicate that the telescopic shaft 762 performs an oblique sliding motion along the inclined area 662; the arrows within the reset area 663 indicate that the telescopic shaft 762 returns upwards along the reset area 663 to the initial end of the sliding area 661. During the return stroke, the telescopic shaft 762 performs an oblique sliding motion along the inclined area 662. It should be noted that the above arrows only indicate the direction of movement and do not change the connection relationship or working principle between the components; finally, the hydraulic cylinder 62 reverses its return stroke, moving the... The movable plate frame 71 is pulled back to its initial position, ready to pick up the next piece of fabric 5, and the servo motor 103 rotates in the opposite direction, causing the belt conveyor mechanism 101 to drive the bearing plates 104 on both sides to move in the opposite direction on the guide plate frame 105. The bearing plates 104 drive the fixed shaft 9 and the glue spray gun 91 to perform a reverse reset movement. During this process, the glue spray gun 91 will not come into contact with the mattress body 4 with the fabric 5 after glue application. The mattress body 4 with glue application is then conveyed by the mattress conveyor mechanism 1 through the flattening roller and sent into the self-sewing mechanism 2 for edge sewing. This cycle can achieve continuous and efficient glue application and laying operation of the mattress body 4, thereby improving the glue application and sewing efficiency.
