Description

Technical Field

[0001] This invention relates to a processing apparatus for medical fabrics, and more particularly to a processing apparatus for medical transfer pads. Background Technology

[0002] Disposable medical transfer pads are tools used for moving critically ill patients. They can be used for patient transfer during emergency care, examinations, and surgeries, as well as for cleaning and lateral positioning nursing care. In existing technologies, disposable medical transfer pads typically consist of a pad body and a reinforcing structure on the outer side of the pad body. Workers use the outer side of the pad body as a force point to lift the disposable medical transfer pad and the patient for transfer; therefore, the outer force point needs a reinforcing structure. For example, a disposable patient transfer pad disclosed in patent document CN207886389U employs an outer protective layer. Generally, disposable medical transfer pads include a non-woven fabric middle section and reinforcing fabric on the sides of the non-woven fabric. Reinforcing fabric is folded and fixed to the upper and lower surfaces of the sides to form a reinforcing structure. In existing technologies, disposable medical transfer pads are generally fixed by manual folding. Patent document CN218666631U discloses a textile material folding device for folding the base fabric of a bag. This device uses a U-shaped rolled edge, and by reducing the diameter of the rolled edge, the base fabric is folded and tightly adhered together. However, the drawback is that disposable medical transfer pads are made by combining two independent layers of fabric, and the pads are relatively wide, typically the same width as the bed. This folding device, using a rolled edge with a reduced diameter, is prone to jamming during the processing of disposable medical transfer pads, making continuous processing difficult. Summary of the Invention

[0003] To address the above shortcomings, the present invention aims to provide a processing apparatus suitable for the continuous processing of disposable medical transfer pads.

[0004] Therefore, the present invention provides a processing apparatus for medical fabric, wherein the medical fabric includes a first fabric, characterized in that: it includes a folding device, the folding device includes a folding assembly, the folding assembly includes a pressing edge and a folding edge, the folding edge is disposed on one side of the pressing edge, and a gap is provided between the folding edge and the pressing edge, a first part of the first fabric is disposed on the side of the pressing edge away from the folding edge and moves under the action of a conveying device, and a second part of the first fabric is disposed in the gap between the pressing edge and the folding edge, and as the first fabric moves, the second part is folded to the side of the pressing edge close to the folding edge.

[0005] Furthermore, the folded edge and the pressing edge are arranged intersectingly, and along the moving direction of the first fabric, the folded edge is obliquely towards the folding direction of the first fabric.

[0006] Furthermore, the folding assembly includes a pressure plate and a folding plate. The pressure plate is located on the side of the pressure plate, and the folding plate is located on the side of the folding plate opposite to the pressure plate. The folding plate and the pressure plate are staggered on one side. Along the moving direction of the first fabric, the width of the projection of the folding plate onto the pressure plate gradually increases, so that the second part of the first fabric is gradually folded.

[0007] Furthermore, the width of the rear end of the folded plate covers the width of the first fabric after folding.

[0008] Furthermore, the folding assembly also includes a guide plate, which is located in the opposite direction to the movement direction of the pressure plate and the first fabric. The guide plate is inclined and its two sides converge inward along the movement direction of the first fabric. The guide plate is used to change the angle formed between the second part and the first part of the first fabric, so that the second part deforms in the folding direction.

[0009] Furthermore, the pressure plate is inclined, and the pressure plate and the guide plate form a V-shaped angle.

[0010] Furthermore, the guide plate and the pressure plate are integrally formed, and a connecting block is provided on the pressure plate. The connecting block is connected to a connecting rod, and the connecting rod is fixed on the frame of this equipment. In this way, the guide plate and the pressure plate are suspended and fixed on the frame. A bracket is connected to the folding plate, and the bracket is connected to the frame. In this way, the folding plate is suspended and fixed on the frame.

[0011] Furthermore, the medical fabric includes a second fabric, a first portion of the first fabric is placed on one side surface of the corresponding edge of the second fabric, and the second portion of the first fabric is fixed to the other side surface of the second fabric after the first fabric is folded to form a reinforcing structure.

[0012] Furthermore, it also includes a second feeding rack and two first feeding racks. The first feeding racks are located on both sides of the second feeding rack. The second fabric is discharged from the second feeding rack, and the first fabric is discharged from the corresponding first feeding rack. After the first fabric and the second fabric pass through the clamping roller, the surfaces of both sides of the second fabric are placed on the first part of the first fabric. After the first fabric and the second fabric are combined and passed through the hemming assembly, the first part and the second part of the first fabric are respectively placed on the upper and lower surfaces of both sides of the second fabric.

[0013] Furthermore, it also includes welding equipment, punching equipment, and folding equipment. The welding equipment is located behind the folding equipment and is used to weld the first and second fabrics. The punching equipment is located behind the welding equipment and punches holes for handles at the overlapping position of the first and second fabrics. The folding equipment is located behind the punching equipment and is used to fold the finished product.

[0014] The beneficial effects of this invention are as follows:

[0015] (1) The processing device of the present invention includes a folding assembly. During continuous processing, a first part of the first fabric is disposed on one side of the pressing edge (as shown below the surface), and a second part is folded in the gap between the pressing edge and the folding edge. When the first fabric is driven forward continuously by the fabric roller, the second part of the fabric will be continuously folded through the gap between the pressing edge and the folding edge, thereby realizing continuous folding.

[0016] (2) In a specific embodiment of the present invention, the folding plate and the pressing plate are respectively provided on opposite sides, and the pressing edge and the folding edge are arranged in a cross manner, so that the second part of the first fabric is gradually folded, the folding resistance is significantly reduced, and the folding is smoother.

[0017] (3) In a specific embodiment of the present invention, a guide plate is also provided. The two sides of the guide plate are tapered inward along the moving direction of the fabric. The guide plate and the pressure plate form a V-shaped structure, so that the second part of the second fabric strip gradually deforms upward under the action of the guide plate and folds into an acute angle or a 90° angle. Then, through the action of the obliquely set folding plate, the folding process is further lengthened, so that the folding process of this specific embodiment does not involve large-angle folding. The second part of the first fabric is folded through continuous small angle changes. The process is smooth and easy to process. Attached Figure Description

[0026] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0027] Reference Figure 5 and Figure 6 As shown, the medical fabric includes a second fabric 11 serving as the main body of the disposable medical transfer pad 9, and a first fabric 10 folded and fixed to the upper and lower surfaces of both sides of the second fabric 11 as a reinforcing structure. Both the first fabric 10 and the second fabric 11 can be made of non-woven fabric. The medical fabric has oval holes 12 for a hand to pass through as a handle for the transfer pad. After being cut, the medical fabric can be used as a disposable medical transfer pad. (Refer to...) Figures 1 to 4 As shown, a medical fabric processing apparatus of the present invention includes a folding device 4, which includes a folding assembly 401. The folding assembly 401 includes a pressing edge 4012 and a folding edge 4014. The folding edge 4014 is disposed on one side of the pressing edge 4012, and a gap is provided between the folding edge 4014 and the pressing edge 4012. A first portion 101 of a first fabric 10 is disposed on the side of the pressing edge 4012 away from the folding edge 4014 and moves under the action of a conveying device. A second portion 102 of the first fabric 10 is disposed in the gap between the pressing edge 4012 and the folding edge 4014, and as the first fabric 10 moves, the second portion 102 is folded to the side of the pressing edge 4012 near the folding edge 4014. In a specific embodiment of the present invention, refer to... Figure 1 As shown, the device includes a first feeding rack 1 and a second feeding rack 2. A roll of first fabric 10 is placed on the first feeding rack 1, and a roll of second fabric 11 is placed on the second feeding rack 2. The first feeding rack 1 is located on the side of the second feeding rack 2. (Refer to...) Figure 1 and Figure 5As shown, after the first fabric 10 and the second fabric 11 pass through the clamping roller 3, which is a conveying device driven by the motor 13, the fabric is fed. The first part 101 of the first fabric 10 (slightly smaller than half the width of the first fabric 10) is placed on the lower surface of the side of the second fabric 11. The combined fabric of the first fabric 10 and the second fabric 11 continuously passes through the folding assembly 401 under the drive of the fabric roller. The pressing edge 4012 abuts against the folded part of the first fabric 10. The folding edge 4014 causes the continuously moving fabric to fold when it passes through the folding edge 4014. After passing through the folding assembly 401, the combined fabric of the first fabric 10 and the second fabric 11... A structure is formed where the first fabric 10 is folded over the side of the second fabric 11. The continuously moving fabric moves to the ultrasonic welding device 5 to weld and fix the joint between the first fabric 10 and the second fabric 11. After the first fabric 10 and the second fabric 11 have been welded by the welding device, they have basically formed the aforementioned medical fabric. After being punched at equal intervals by the punching device 6, it is folded by the folding device 7. It can also be further cut into disposable medical transfer pads by a cutting device. Fabric rollers 8 and clamping rollers 3 can be set between the devices. The clamping rollers 3 are used to drive the fabric to move under the drive of the motor, and the fabric rollers 8 can be used to change the direction of fabric movement. In order to improve production efficiency, this embodiment sets up two first feeding racks 1, and correspondingly performs folding and other processing on both sides of the second fabric 11 at the same time. In this embodiment, the folding assembly 401 includes a pressure plate 4011 and a folding plate 4013. The pressure plate 4011 and the folding plate 4013 are independently arranged. The pressure edge 4012 is provided on the side of the pressure plate 4011, and the folding edge 4014 is provided on the side of the folding plate 4013 opposite to the pressure edge 4012. The folding plate 4013 is provided above the pressure plate 4011 and has a gap. Preferably, the folding edge 4014 of the folding plate 4013 is staggered with the pressure edge 4012 of the pressure plate 4011 on one side. Along the moving direction of the first fabric 10, the width of the projection of the folding plate 4013 on the pressure plate 4011 gradually increases. In this way, the second part 102 of the first fabric 10 is gradually folded after the folding. This method can avoid directly folding the first fabric 10 at once, and the folding is smoother and more accurate. Preferably, the rear end width of the folding plate 4013 covers the width of the first fabric 10 after folding, that is, the rear end of the folding plate 4013 completely covers the folded first fabric 10, which can ensure that the second part 102 of the first fabric 10 is completely folded in place. The aforementioned folding plate 4013 and pressing plate 4011 can be replaced by a strip structure, which can also achieve folding. Specifically, the folding edge 4014 and the pressing edge 4012 are arranged crosswise. Along the moving direction of the first fabric 10, the folding edge 4014 is obliquely oriented towards the folding direction of the first fabric 10, which can also achieve gradual folding and realize the technical effect of continuous moving folding.

[0028] In the above embodiments, reference is made to Figures 1 to 4As shown, the folding assembly 401 also includes a guide plate 4015. The guide plate 4015 is located in the opposite direction to the moving direction of the pressure plate 4011 and the first fabric 10. The guide plate 4015 is inclined and its two sides are converging inward along the moving direction of the first fabric 10. The guide plate 4015 is used to change the angle formed between the second part 102 and the first part 101 of the first fabric 10, so that the second part 102 deforms in the folding direction. In this embodiment, the narrow lower part of the guide plate 4015 is aligned with the folding position of the first fabric 10. As the fabric is stretched, when the first fabric 10 passes through the gradually narrowing side of the inclined guide plate 4015, the second part 102 of the first fabric 10 is subjected to an inward force, causing the first fabric 10 to undergo a certain angle of folding deformation. The second part 102 of the first fabric 10 after a certain folding is folded at a smaller angle by the folding edge 4014. The folding edge 4014 adopts an inclined folding method, which cooperates with the initial folding action of the guide plate 4015, so that the first fabric 10 can complete the entire folding process very smoothly, avoiding the occurrence of jamming or other phenomena. Furthermore, the pressure plate 4011 is inclined, and the pressure plate 4011 and the guide plate 4015 form a V-shaped angle. Specifically, the guide plate 4015 and the pressure plate 4011 are integrally formed and bent. A connecting plate 4016 or block is provided on the pressure plate 4011. The connecting plate 4016 is connected to the connecting rod 4017. The connecting rod 4017 is fixed on the frame 14 of the bending equipment. In this way, the guide plate 4015 and the pressure plate 4011 are suspended and fixed on the frame. The bending plate 4013 is connected to the bracket 4018, and the bracket is connected to the frame. In this way, the bending plate 4013 is suspended and fixed on the frame.

[0029] In the above embodiments, some processing steps of the medical fabric are referred to Figure 7As shown, after the first fabric 10 and the second fabric 11 pass through the longitudinally arranged clamping roller 3, the first fabric 10 is placed on the lower surface of the second fabric 11. The combined fabric of the first fabric 10 and the second fabric 11 changes direction by the clamping roller 3 and is inclined downward along the guide plate 4015. The second part 102 of the first fabric 10 is folded at a certain angle by the action of the side of the guide plate 4015. The second fabric 11 and the first part 101 of the first fabric 10 change direction to inclined upward at the connection between the pressure plate 4011 and the guide plate 4015. The second part 102 of the first fabric 10 is folded by the action of the pressing edge 4012 and the folding edge 4014, and is close to the folding edge assembly 401. Two horizontally arranged fabric rollers 8 are set up, and the relative height of the two fabric rollers 8 is adjustable. They can also be horizontally arranged clamping rollers. The folded combined fabric quickly wraps around the upper side of the first fabric roller, then around the lower side of the second fabric roller, and then around a fabric roller higher than the second fabric roller. As the combined fabric is stretched and its direction is quickly changed, the fold of the first fabric 10 after folding is subjected to strong compression and plastic deformation occurs at the fold position. The first part 101 and the second part 102 of the first fabric 10 are closely attached to the upper and lower surfaces of the second fabric 11. After passing through the higher fabric roller, the combined fabric is in a horizontal state and is welded by an ultrasonic welding device, and the reinforced structure is completed.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
