Description

Technical Field

[0001] The invention relates to the technical field of medical nursing mattress processing, in particular to a nursing mattress processing device with an edge trimming function. Background Art

[0002] Traditional nursing mattresses are mostly made from basic materials like cotton and sponge, sewn or stuffed. However, these mattresses suffer from poor breathability and uneven pressure distribution. Early manufacturing processes relied on manual cutting and sewing, which was inefficient and lacked standardization. Modern processing technologies utilize automated equipment such as CNC cutting to achieve precise molding and sealing, ensuring product consistency and durability. Composite structural design combined with computer-generated pressure distribution simulation is driving the automation and intelligentization of nursing product manufacturing.

[0003] In the existing processing equipment, the automated processing of nursing mattresses relies on CNC machine tools to drive the displacement of the mattresses. Through automated sewing, the single-layer sewn mattresses have the defects of poor edge sealing and insufficient sewing strength. In addition, in the existing automatic sewing equipment, the transportation and adsorption of mattresses often rely on pressure plates of different shapes. When transporting mattresses of different shapes, it is necessary to replace pressure plates of different shapes to ensure that the mattresses remain flat during automatic sewing, to avoid warping and wrinkles in the automatically sewn mattresses that affect product quality. Replacing the pressure plates causes the existing processing equipment to be insufficiently adaptable and to have low production efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a nursing mattress processing device with an edge trimming function to solve the problems in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A nursing mattress processing device with an edge-straightening function includes a base, an inspection platform, a control box, a conveying mechanism, an edge-straightening mechanism and a sewing mechanism. A groove is provided on the base, the conveying mechanism includes a two-axis displacement module, the edge-straightening mechanism includes an assembly rack, and the sewing mechanism includes an automatic sewing machine and a light-emitting panel. The inspection platform, the control box, the two-axis displacement module, the assembly rack, and the automatic sewing machine are all fixedly connected to the base, the light-emitting panel is fixedly connected to the groove, and the inspection platform, the conveying mechanism, and the automatic sewing machine are all connected to the control box through electrical signals.

[0006] The present invention is an automated device for sewing the edges of nursing mattresses. The upper and lower mattresses to be processed are placed on a light-emitting plate. The positions of the mattresses are identified by a visual inspection platform. The two-axis displacement module drives the side frame to move above the mattresses. After the mattresses are adsorbed, the side frame is driven to slide on the bottom platform. The posture of the mattresses is corrected so that their edges are aligned with the edge straightening mechanism. The transport mechanism detects the tension of the mattresses during adsorption in real time and feeds back an electrical signal to a control box. The control box calculates the tension limit of the mattresses and feeds back a control signal to the tensioning mechanism and the foot support mechanism to correct the surface tension of the mattresses in real time. The bionic simulation of manual sewing operation flattens the mattress, so that it is in a tension balance state to avoid the mattress from warping and bending. The two-axis displacement module drives the adsorption mattress to move to the edge straightening mechanism. The edge straightening mechanism irons the edge of the mattress to eliminate wrinkles, and folds the edges of the upper and lower mattresses to be processed inward. The automatic sewing machine automatically sews the edges of the inward-folded mattresses. The sewn edges of the mattresses are neatly wrapped inward, and the mattresses are wrinkle-free and flat, which greatly improves the sealing effect and sewing strength of the mattress edges and greatly improves the work efficiency of mattress processing.

[0007] Furthermore, the transport mechanism also includes a side frame, a first cylinder, a servo motor, a tensioning mechanism and a support mechanism. The side frame is fixedly connected to the two-axis displacement module and the first cylinder. The servo motor is fixedly connected to the output end of the first cylinder. A slide rail is provided on the side frame. The servo motor is slidably connected to the slide rail. The tensioning mechanism includes a main shaft and a round table. The output end of the servo motor is fixedly connected to the main shaft. A ring rail is provided on the round table. The support mechanism is provided with several groups, and several groups of support mechanisms are evenly distributed along the circumference of the round table. The support mechanism includes a tripod and a pulley. The tripod is slidably connected to the round table, and the pulley is rotatably connected to the ring rail. The first cylinder, servo motor, tensioning mechanism and support mechanism are all connected to the control box through electrical signals.

[0008] The inspection platform identifies the position of the mattress, and the two-axis displacement module drives the side frame to move above the mattress. The output end of the first cylinder pushes the servo motor to slide downward along the slide rail. After the main suction cup absorbs the mattress, the two-axis displacement module drives the mattress to slide on the base platform, and the servo motor outputs a fixed-axis torque to the main shaft, correcting the mattress posture so that its edge is aligned with the edge straightening mechanism. Several groups of support mechanisms detect the tension in all directions of the mattress when it is absorbed in real time, and feed back electrical signals to the control box. The control box calculates the mattress tension limit, and feeds back control signals to the tensioning mechanism and the support mechanism, correcting the mattress surface tension in real time, and bionic simulation of manual sewing operations to flatten the mattress so that it is in a tension balance state.

[0009] Furthermore, the tensioning mechanism also includes a displacement cylinder and a main suction cup. A side platform is provided on the main shaft. The displacement cylinder is fixedly connected to the side platform. The output end of the displacement cylinder is fixedly connected to the round table. The round table is slidingly connected to the main shaft. The main suction cup is fixedly connected to the main shaft. The displacement cylinder and the main suction cup are both connected to the control box through electrical signals.

[0010] The control box calculates the mattress tension limit and feeds back the control signal to the tensioning mechanism and the foot-supporting mechanism. The output end of the displacement cylinder pushes the round table to slide along the main shaft, adjusts the distance between the foot-supporting mechanism and the main shaft, and provides timely feedback and adjustment of the mattress pressing position when simulating manual sewing. The mattress surface tension is corrected in real time, and the flattening operation of the mattress is simulated by the manual sewing operation.

[0011] Furthermore, the leg supporting mechanism also includes a servo cylinder, an articulated rod, an auxiliary suction cup, a slide, an articulated seat, a pressure sensor and a first motor. The tripod is provided with a first articulated buckle and a second articulated buckle. The servo cylinder is articulated to the first articulated buckle. The output end of the servo cylinder is articulated to the auxiliary suction cup. The articulated rod is articulated to the second articulated buckle and the articulated seat. The slide is fixedly connected to the auxiliary suction cup. The articulated seat is slidably connected to the slide. The articulated seat and the slide are fixedly connected to the pressure sensor. The first motor is fixedly connected to the tripod. The output end of the first motor is fixedly connected to the pulley. The servo cylinder, the auxiliary suction cup, the pressure sensor and the first motor are all connected to the control box through electrical signals.

[0012] The auxiliary suction cup contacts the mattress surface, and the output end of the displacement cylinder pushes the round table to slide down along the main axis. The hinge rod and the second hinge buckle and the hinge seat on the tripod are hinged and assembled. The hinge rod pushes the hinge seat to slide along the slide away from the main axis. The output end of the servo cylinder changes the distance from the auxiliary suction cup, and the auxiliary suction cup absorbs the mattress surface and expands outward. When the surface tension of the mattress is at the flatness limit, the elastic stress of the built-in spring of the pressure sensor restores the deformation and is balanced with the surface tension of the mattress, and continuously squeezes the built-in spring of the pressure sensor itself. The pressure sensor reading changes, and the control box controls the auxiliary suction cup to stop tensioning the mattress. The fixed-axis torque is output to the pulley through the first motor. The pulley and the ring rail are rolled and assembled to drive several groups of auxiliary suction cups to rotate around the main axis. The spacing between several groups of auxiliary suction cups is adjusted. When the manual sewing operation is simulated bionically, when the mattress is manually flattened and tensioned, the palm of the hand contacts various parts of the mattress.

[0013] Furthermore, the edge straightening mechanism also includes a driving motor, a bevel gear set, a leveling mechanism and an inward folding mechanism. The leveling mechanism also includes a frame shell and a steam cylinder. The inward folding mechanism includes a side shell. The driving motor, frame shell and side shell are all fixedly connected to the assembly frame. The bevel gear set is fixedly connected to the output end of the driving motor and the steam cylinder.

[0014] The two-axis displacement module drives the adsorption mattress to move to the edge straightening mechanism, corrects the mattress posture so that its edge is aligned with the frame shell, and drives the motor to output the fixed-axis torque to the bevel gear set. The bevel gear set transmits the torque to the steam cylinder. The steam cylinder rotates to iron the edge of the mattress to eliminate wrinkles. The mattress continues to pass through the inward folding mechanism, and the edges of the upper and lower mattresses to be processed are folded inward to complete the neat inner wrapping of the mattress edges.

[0015] Furthermore, the leveling mechanism also includes a first gear disc and a second gear disc, and the frame shell is provided with an assembly hole, and the assembly holes and the steam cylinder are provided with two groups. The first gear disc and the second gear disc are fixedly connected to the steam cylinder, and the steam cylinder is rotatably connected to the assembly hole. The tooth surfaces of the first gear disc and the second gear disc are engaged, and the steam cylinder is provided with air holes, and the air holes are provided in several groups, and the several groups of air holes are evenly distributed along the cylinder surface of the steam cylinder.

[0016] The driving motor outputs fixed-axis torque, which is transmitted to the steam cylinder through the bevel gear set. The upper and lower groups of steam cylinders rotate toward each other through the meshing of the tooth surfaces between the first gear disc and the second gear disc. The two-axis displacement module drives the adsorption mattress to move between the upper and lower groups of steam cylinders. High-temperature steam is introduced into the steam cylinder from the outside, and the steam is discharged onto the mattress from several groups of air holes evenly distributed along the surface of the steam cylinder. The upper and lower groups of steam cylinders rotate toward each other to coordinate with the displacement of the adsorption mattress to iron the edges of the mattress to eliminate wrinkles.

[0017] Furthermore, the inward folding mechanism also includes a separation cone plate, a return bending plate and a curved surface table. The separation cone plate, the return bending plate and the curved surface table are all fixedly connected to the side shell. There are two groups of separation cone plates, the return bending plate and the curved surface table. The two groups of separation cone plates, the return bending plate and the curved surface table are arranged in a mirror-symmetrical manner.

[0018] The two-axis displacement module drives the adsorption mattress to move to the separation cone plate, and the upper and lower groups of mattress fabrics are separated by the conical surface of the separation cone plate. The mattress fabric continues to move along the return bending plate, and the mattress fabric twists along the gap between the return bending plate and the curved table. The edges of the upper and lower mattresses to be processed are folded inward to complete the neat inner wrapping of the mattress edges.

[0019] Furthermore, the sewing mechanism also includes a feed tube and a pad, and both the feed tube and the pad are fixedly connected to the automatic sewing machine.

[0020] The two-axis displacement module drives the adsorption mattress to move to the pad, and the edge of the inward-folded mattress is automatically sewn by an automatic sewing machine. The cut fabric threads fall into the discharge pipe for recycling.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a tensioning mechanism, which pushes the round table to slide through the output end of the displacement cylinder, and the auxiliary suction cup contacts the surface of the mattress. The hinged rod and the second hinge buckle and the hinge seat on the tripod are all hinged and assembled. The hinged rod pushes the hinge seat to slide along the slide away from the main axis. The output end of the servo cylinder changes the distance from the auxiliary suction cup, and the auxiliary suction cup absorbs the surface of the mattress and expands outward. The surface tension of the mattress is at the leveling limit. The elastic stress of the built-in spring of the pressure sensor restores the deformation and is balanced with the surface tension of the mattress. The built-in spring of the pressure sensor itself is continuously squeezed, and the pressure sensor reading changes. The control box feeds back the auxiliary suction cup to stop tensioning the mattress. The first motor drives several groups of auxiliary suction cups to rotate around the main axis, and the distance between several groups of auxiliary suction cups is adjusted. When the bionic simulation is artificially flattening and tensioning the mattress, the palm of the hand contacts the various parts of the mattress and presses the position of the mattress. Timely feedback and adjustment are provided, and the surface tension of the mattress is corrected in real time. The flattening operation of the mattress is simulated bionically by manual sewing. The present invention designs an edge straightening mechanism, and the driving motor outputs a fixed-axis torque. The upper and lower groups of steam cylinders rotate toward each other, and high-temperature steam is introduced into the steam cylinder through the outside. The steam is discharged onto the mattress from several groups of air holes evenly distributed along the cylinder surface of the steam cylinder, and the edge of the mattress is ironed to eliminate wrinkles. The conical surface of the separation cone plate separates the upper and lower groups of mattress fabrics, and the mattress fabric is twisted along the gap between the return bending plate and the curved surface table. The edges of the upper and lower mattresses to be processed are folded inwardly to complete the neat inner wrapping of the mattress edges. The present invention automatically absorbs and transports mattresses, detects and corrects the mattress tension in real time, and bionic simulates the flattening operation of manual sewing, so that the mattress is in a tension balance state to avoid warping, and is ironed to eliminate wrinkles, and the edges are wrapped inward, which greatly improves the sealing effect and strength of the mattress and improves production efficiency.

[0048] The working principle of the present invention is as follows: the upper and lower mattresses to be processed are placed on the light-emitting plate 64, the position of the mattress is identified by the visual inspection platform 2, the mattress is adsorbed and driven to slide on the bottom platform 1, the posture of the mattress is corrected so that its edge is aligned with the edge straightening mechanism 5, the auxiliary suction cup 464 contacts the mattress surface, the output end of the displacement cylinder 452 pushes the round table 453 to slide downward along the main shaft 451, and the second hinge buckle 4612 and the hinge seat 466 on the tripod 461 are hingedly assembled through the hinge rod 463, the hinge rod 463 pushes the hinge seat 466 to slide along the slide 465 away from the main shaft 451, the output end of the servo cylinder 462 changes the distance with the auxiliary suction cup 464, the auxiliary suction cup 464 adsorbs the mattress surface and expands outward, when the mattress surface tension is at the leveling limit, the elastic stress of the built-in spring of the pressure sensor 467 restores the deformation and is balanced with the mattress surface tension, the built-in spring of the pressure sensor 467 is continuously squeezed, and the reading of the pressure sensor 467 changes. The control box 3 controls the auxiliary suction cup 464 to stop tensioning the mattress, and outputs a fixed-axis torque to the pulley 469 through the first motor 468. The pulley 469 is rollingly assembled with the ring rail 4531, driving several groups of auxiliary suction cups 464 to rotate around the main shaft 451, and the spacing between several groups of auxiliary suction cups 464 is adjusted. When the mattress is flattened and tensioned by humans, the contact points of the palm on various parts of the mattress are bionic simulated, and the surface tension of the mattress is corrected in real time. The flattening operation of the mattress by bionic simulation of manual sewing operation is put into a tension balance state to prevent the mattress from warping and bending. The two-axis displacement module 41 drives the adsorbed mattress to move to the edge straightening mechanism 5, and the edge straightening mechanism 5 irons the edge of the mattress to eliminate wrinkles, folds the edges of the upper and lower mattresses to be processed inward, and the automatic sewing machine 61 automatically sews the edges of the folded mattresses. The sewn edges of the mattresses are neatly wrapped inward, and the mattresses are wrinkle-free and flat, which greatly improves the sealing effect and sewing strength of the mattress edges and greatly improves the work efficiency of mattress processing.
