Description

Technical Field

[0001] This invention belongs to the field of medical dressing production technology, and specifically relates to an automated preparation device and method for bandages. Background Technology

[0002] Bandages are common medical and hygiene products, generally made of gauze or cotton cloth, primarily used to bandage wounds and prevent infection. After processing, medical gauze bandages are usually in large, thick rolls. To facilitate subsequent use, these rolls are rolled to a fixed length to obtain smaller rolls of a certain thickness. Then, a layer of paper is wrapped around them. Finally, they are cut to obtain the bandages.

Between the driven fabric roll and the pressing roll, the yarn drawn from the yarn feeding rack passes through the lower side of the telescopic mandrel. A connecting rod is hinged between the pressing roll and the frame. A pressing telescopic cylinder that drives the connecting rod to rotate is hinged to the upper end of the frame. The telescopic end of the pressing telescopic cylinder is hinged to the middle of the connecting rod. A push-roll plate is located on the upper left side of the telescopic mandrel, with an L-shaped cross-section. A push-roll telescopic cylinder that drives the push-roll plate to move is fixedly installed on the frame. The push-roll telescopic cylinder is inclined, and the push-roll plate is installed on the telescopic end of the push-roll telescopic cylinder. There are two telescopic mandrels, symmetrically arranged at the front and rear of the frame. A shaft seat is fixedly connected to the outer end of each telescopic mandrel. A core-pulling telescopic cylinder is installed between the shaft seat and the frame. A first guide rod is also installed between the shaft seat and the frame. Each shaft seat is fixedly connected to two first guide rods. The first guide rods are symmetrically arranged on the core-pulling telescopic cylinder. On both sides of the telescopic cylinder, the first guide rod is slidably connected to the frame; a guide plate is inclinedly arranged on the lower right side of the telescopic core shaft, a cutting groove is arranged in the middle of the guide plate, and a cutting knife is arranged in the cutting groove; a knife holder supporting the cutting knife is slidably connected to the frame; the paper cutting and glue spraying device is arranged at the upper right end of the frame, and the paper cutting and glue spraying device includes a paper feeding roller group, a glue spraying frame and an inclined guide plate. The paper feeding roller group captures the paper roll from the paper roll feeding roller. The paper feeding roller group includes two paper feeding rollers, one of which is connected to a paper feeding motor. The glue spraying frame is slidably connected to the frame, and the glue spraying frame is equipped with a glue spraying head and a paper cutter. The guide plate is equipped with a paper cutting groove, and the paper cutter is located in the paper cutting groove; the bandage wrapping device is arranged below the paper cutting and glue spraying device, and the bandage wrapping device includes a first wrapping roller and a second wrapping roller supporting the bandage roll. The paper wrapping roller, the first paper wrapping roller, and the second paper wrapping roller are each connected to a paper wrapping motor at one end. Spring telescopic support rods are connected to both ends of the first and second paper wrapping rollers. A pressure roller is installed on the upper side of the middle of the first and second paper wrapping rollers, and pressure telescopic cylinders are installed on the upper sides of both ends of the pressure roller. The gauze feeding frame has a rectangular frame structure. One end of the gauze feeding frame is hinged to the machine frame, and the other end is equipped with a gauze roller supporting the gauze roll. A support telescopic cylinder is installed between the end of the gauze feeding frame away from the hinge point and the machine frame. A feeding guide roller is installed on the left end of the machine frame. An intermediate guide roller is also installed between the gauze core pulling and winding device and the gauze feeding frame. The intermediate guide roller includes a driving roller and a driven roller. A winding motor is fixedly installed on the machine frame, and the winding motor is connected to the driving roller and the driving winding roller respectively via a transmission belt.

[0004] For example, patent application number CN201620399589.1 discloses a fully automatic bandage machine, including a frame, a roll of raw fabric on an extension frame at the front of the frame, a fabric winding device, a fabric cutting device, a power device, and a program control device. The fabric winding device is characterized in that: the front end of the yarn on the raw fabric roll is wound onto a mandrel via a guide roller and / or a spreading roller; the mandrel is positioned above between winding roller A and winding roller B; the mandrel is controlled by a transverse telescopic device, the extension and retraction of which are controlled by a computer-programmed push-shaft cylinder; winding roller A and winding roller B are meshed by gears on one side. The rolls rotate in opposite directions. Under the rotation of the winding rollers A and B, the gauze roll continuously rotates and gradually thickens, forming bandage roll A. Above bandage roll A, a pressure roller A is also installed, which always presses against the bandage roll A. The shaft of pressure roller A is placed in a longitudinal slot and can move up and down along the slot. An elastic pressing device is installed on the shaft of pressure roller A. As the bandage roll A thickens, the shaft of pressure roller A gradually rises, and the push rod at the top of the shaft acts on the pushing device. Finally, when the bandage roll A gradually reaches the set diameter or length, the computer program controls the automatic stopping of the winding process, and the mandrel, under the action of the telescopic device, moves from the bandage roll. The bandage roll A is pulled out; the bandage roll A is pushed backward by the pushing device; the bandage roll A rolls backward along the slope on the frame to the position of the bandage roll B; at this time, the cloth cutting device cuts the gauze behind the bandage roll B under the instruction of the computer program; the mandrel extends under the action of the telescopic device, presses down the end of the cut gauze, and wraps around the mandrel under the winding action; as the bandage roll A rolls out, the pressure roller A falls, the pushing device returns to its original state, thus starting the next winding process of the bandage roll A; after the bandage roll B enters the position, the paper roll inserts the lower end of the packaging paper into the cloth head of the bandage roll B through the paper feeding device, then the paper feeding device stops working, and at this time the paper cutting and glue spraying device starts. The process begins with cutting the packaging paper and applying adhesive to the cut ends. Rewinding rollers A and B rotate in opposite directions via gear meshing on one side. Under the rotation of rewinding rollers A and B, the bandage roll B begins to rotate, gradually wrapping the packaging paper around the fabric end and attaching it to the outside of the bandage roll B. Pressure roller B is positioned above the bandage roll B, with its shaft placed within a longitudinal slot. The shaft of pressure roller B can move up and down along the slot, and an elastic pressing device is installed on the shaft, allowing pressure roller B to press the bandage roll B tightly. After wrapping is complete, the computer automatically activates the cylinder, causing rewinding roller B to retract, allowing the finished bandage roll B to automatically fall into the receiving cart.

Specifically, multiple L-shaped plates are arranged side by side on the lifting belt 22, forming a U-shaped groove 23 with the lifting belt 22. The rear end of the horizontal arm of the L-shaped plate on the front side of the lifting belt 22 is fixedly connected to the front side of the lifting belt 22, and its vertical arm (located on the rear side of the bandage strip 4) is located on the upper side of the front end of the horizontal arm.

[0042] The guide plate 21 is arranged diagonally downwards from front to back. Its upper end is located below and in front of the top of the lifting belt 22, and its lower end is located directly above the feeding conveyor mechanism. Multiple clearance notches 24 (corresponding one-to-one with the lifting belt 22) are arranged side-by-side on its upper end to allow the passage of the U-shaped grooves 23. Friction deceleration strips 25 and lifting baffles 26 are arranged sequentially from top to bottom on the guide plate. The clearance notches 24 are rectangular notches that allow the passage of L-shaped plates and are arranged along the front-back direction. Both the friction deceleration strips 25 and the lifting baffles 26 are used to decelerate the bandage strips 4. There are multiple friction deceleration strips 25 (2-6 strips), arranged side-by-side with intervals. The friction deceleration strips 25 are rectangular strips arranged along the left-right direction. The lifting baffles 26 are arranged along the left-right direction and can move up and down, preventing the bandage strips 4 from rolling downwards. Specifically, the lifting baffle 26 is perpendicular to the guide plate 21 and is located below the guide plate 21. It can move upward (driven by a corresponding structure, specifically a cylinder) to above the guide plate 21 to block the bandage strip 4, and then descend after a first predetermined time (e.g., 0.1s) to allow the bandage strip 4 to pass through. The guide plate 21 has slits along its left and right sides for the lifting baffle 26 to pass through. More specifically, there are multiple lifting baffles 26, which are arranged side by side and driven synchronously.

[0043] When used for producing bandage strip 4, the receiving trough 9 is installed, the transfer structure 10 is removed, and the bandage cutting structure 11 and the bandage strip lifting structure 12 are not in operation.

[0044] When used for bandage production, the transfer structure 10 is installed, the receiving trough 9 is removed, and both the bandage cutting structure 11 and the bandage strip lifting structure 12 are operational. At this time, the discharge trough is positioned diagonally downwards from front to back, with its front directly below the bandage wrapping structure 8. Multiple guide strips are arranged side-by-side, interleaving with the lifting belt 22, and are located on the same inclined plane as the discharge trough. The guide strips are positioned diagonally downwards from front to back, with their front ends connected to the rear end of the discharge trough and their rear ends detachably connected to the bottom of the support. They guide the bandage strips 4 backwards into the U-shaped groove 23 at the bottom front of the lifting belt 22; these are specifically thin metal strips.

[0045] Among them, see Figure 1-5 The gauze core-pulling and winding structure 5 in this embodiment of the invention includes a pressure roller, a pusher plate, two telescopic mandrels 52, and two winding rollers 51. The two winding rollers 51 are arranged side-by-side, driven synchronously, and are mounted on the frame 1 in the left-right direction; they are rough-surfaced rollers. The pressure roller is located above the two winding rollers 51 and can move up and down (mounted on a corresponding pressure arm and driven by a cylinder); it is mounted in the left-right direction and is a smooth roller, capable of pressing against the upper side of the bandage strip 4. The pusher plate is located directly in front of the bandage strip 4 on the two winding rollers 51 and can move backward to push the bandage strip 4 backward; it is mounted in the left-right direction and is driven by a corresponding cylinder; specifically, it is an L-shaped plate. Two telescopic spindles 52 are located on the left and right sides of the frame 1, respectively. They are arranged in the left-right direction and are positioned above the adjacent sections between the two fabric rolling rollers 51. They can move left and right, and can move synchronously towards and away from each other. They are smooth round rods (diameter less than 1 cm). When the two telescopic spindles 52 are facing each other, their opposite ends are adjacent to each other. When the two telescopic spindles 52 are away from each other, their opposite ends are located on the outer sides of the corresponding sides of the bandage strip 4.

[0046] See Figure 3-5 The frame 1 has two bearing seats 53 on its left and right sides for driving the telescopic spindle 52 on the corresponding sides to move left and right. On the frame 1 (left and right sides), outside the fabric rolling roller 51, there are two support blocks 54, two cleaning grooves 55, and two guide rails 56. The support blocks 54 are arranged in the front-back direction, located adjacent to the outer side of the fabric rolling roller 51. They have V-shaped grooves along their left-right direction that mate with the telescopic spindle 52, supporting the telescopic spindle 52 so that its inner end is suspended relative to the fabric rolling roller 51 to prevent wear. The cleaning grooves 55 are arranged in the front-back direction, with notches on their left and right sides for the telescopic spindle 52 to pass through. Two cleaning sponges are placed inside each groove, one on the front and one on the back of the telescopic spindle 52. There is a gap between the two cleaning sponges (the upper part of the gap is a flared opening to ensure the telescopic spindle 52), which respectively contact the front and rear sides of the telescopic spindle 52. It is a soft structure and is used to clean the telescopic spindle 52.

[0047] See Figure 3-5 The guide rail 56 is located on the outer side of the corresponding side of the frame 1 along the left-right direction. The bearing seat 53 is slidably mounted on the guide rail 56, and a rotating seat 57 and a cylinder seat 58 are sequentially mounted on it from the inside to the outside, arranged along the left-right direction and driven by corresponding structures to move left and right. The two bearing seats 53 are driven synchronously. The rotating seat 57 is provided with a bushing 59 that can move up and down and rotate, and the bushing 59 is arranged along the front-back direction. The telescopic spindle 52 is rotatably mounted on the bushing 59. The cylinder seat 58 is located at the outer end of the telescopic spindle 52, and a tilting cylinder 510 is provided on it and directly above the outer end of the telescopic spindle 52. The two tilting cylinders 510 are driven synchronously. The tilting cylinder 510 is arranged vertically downwards, and the lower end of its telescopic rod has an inverted U-shaped notch along the vertical direction that cooperates with the telescopic spindle 52.

[0048] As the bandage strip 4 on the telescopic spindle 52 gradually increases in size, the telescopic spindle 52 gradually rises. When the two telescopic spindles 52 move towards each other, the bearing seat 53 moves inward, the tilting cylinder 510 extends, and the inverted U-shaped notch presses against the outer end of the telescopic spindle 52, causing the inner end of the telescopic spindle 52 to tilt upward. When the telescopic spindles 52 are in the opposite direction, the tilting cylinder 510 retracts, and the telescopic spindle 52 becomes horizontal and rests on the support block 54.

[0049] Specifically, the rotating base 57 includes two rotating arms arranged side by side, one in front of the other. Each rotating arm is vertically oriented and has an elongated hole along its vertical direction. A bushing 59 is located between the two rotating arms, with corresponding rotating shafts at its front and rear ends. Both rotating shafts are arranged horizontally, aligned on the same straight line, and are located within the elongated holes of the two rotating arms, allowing them to rotate and move vertically within these holes. The cylinder base 58 is a portal frame.

[0050] Among them, see Figure 1-2 The fabric cutting structure 6 in this embodiment of the invention includes a lower slide plate 61, a fabric cutting knife 62, a deceleration baffle 63, and multiple air nozzles. The lower slide plate 61 is arranged diagonally downwards from front to back, with its front end located adjacent to the rear of the fabric rolling roller 51 and its rear end located adjacent to the front of the bandage wrapping structure 8. A knife groove is provided along its upper edge in a left-right direction to cooperate with the fabric cutting knife 62. The fabric cutting knife 62 is located in the middle of the lower slide plate 61 and can move left-right; it is used to cut the fabric 2. Multiple air nozzles are arranged side-by-side on the lower front side of the lower slide plate 61, and can blow air forward to move the rear end of the cut fabric 2 forward to cover the telescopic mandrel 52. The deceleration baffle 63 is located above the lower slide plate 61 and can move up and down. It is arranged in a left-right direction and is located above and behind the fabric cutting knife 62; it is used to block the bandage strip 4 from moving backwards and to decelerate the bandage strip 4. After a second predetermined time (e.g., 0.1s), the deceleration baffle 63 rises to allow the bandage strip 4 to pass. Specifically, the deceleration baffle 63 is an L-shaped plate that is driven by a corresponding cylinder and moves diagonally downwards from front to back.

[0051] Among them, see Figure 1-2 The paper-cutting and glue-spraying structure 7 in this embodiment of the invention includes an upper slide plate 71, a roller conveying mechanism 72, a paper cutter 73, a glue spraying head (not shown), and a paper pressing mechanism 74. The upper slide plate 71 is arranged obliquely downwards from front to back, located above the lower slide plate 61. Its inclination angle (greater than 40°) is greater than the inclination angle of the lower slide plate 61 (less than 30°). Its upper end is located adjacent to and below the roller conveying mechanism 72, and its lower end is located above the bandage-wrapping paper structure 8. A groove for the paper cutter 73 is provided along its upper edge in a left-right direction. The roller conveying mechanism 72 is arranged in a left-right direction and is located behind the paper unwinding structure. The paper cutter 73 is located above the upper slide plate 71 and can move left-right; it is used to cut the paper 3. The glue spraying head follows the movement of the paper cutter 73, spraying glue onto the cut portion of the paper 3 to ensure that the paper 3 forms a cylinder that covers the bandage strip 4. The paper pressing mechanism 74 is located above the lower part of the upper slide plate 71. This vertically movable mechanism 74 presses the paper 3 firmly onto the upper slide plate 71 during its downward movement. It includes a pressure rod arranged horizontally, a drive assembly that drives the pressure rod vertically, and multiple (3-6) pressure plates arranged side-by-side below the pressure rod. The pressure rod can move vertically perpendicular to the upper slide plate 71, and the pressure plates are parallel to the upper slide plate 71. When the paper cutter 73 cuts the paper 3, the pressure plate presses against the upper side of the paper 3 as the paper pressing mechanism 74 moves downward. After cutting, the paper pressing mechanism 74 rises, and the cut paper 3 slides down into the bandage-wrapped paper structure 8.

[0052] Among them, see Figure 1-2 In embodiment 6, the bandage wrapping structure 8 includes a stop bar, a pressure roller, a wrapping drive assembly, and two wrapping rollers 81. The two wrapping rollers 81 are arranged side-by-side, both being rough-surfaced rollers, and are positioned in the left-right direction. The rear wrapping roller 81 is mounted on the frame 1 (fixed), while the front wrapping roller 81 can move back and forth. The pressure roller is located above and between the two wrapping rollers 81, and can move up and down (driven by a corresponding cylinder). It is positioned in the left-right direction, is a smooth roller, and can press against the upper side of the bandage strip 4. The stop bar is located adjacent to and above the rear wrapping roller 81, and serves to block and limit the bandage strip 4; it is positioned in the left-right direction on the frame 1.

[0053] Among them, see Figure 6The paper-wrapping drive assembly is used to drive the two paper-wrapping rollers 81 to move towards and away from each other (achieved by the forward and backward movement of the front paper-wrapping roller 81). When the two paper-wrapping rollers 81 are in the separated state, the straps 4 on them fall downward from the gap between them. The paper-wrapping drive assembly includes a drive motor, two horizontal slide rails 82, two inclined slide rails 83, two synchronous chains 84, two horizontal slide blocks 85, two inclined slide blocks 86, two synchronous sprockets 87, two first cylinders 88, and two second cylinders 89. The two horizontal slide rails 82 are arranged side by side on the left and right sides of the frame 1, both arranged in the forward and backward direction, and are located directly in front of the left and right ends of the rear paper-wrapping roller 81, respectively, and are equipped with limiting structures. The two horizontal slide blocks 85 are slidably mounted on the two horizontal slide rails 82, and the left and right ends of the front paper-wrapping roller 81 are respectively mounted on the two horizontal slide blocks 85. Two inclined slide rails 83 are arranged side-by-side on the left and right sides of the frame 1, located below the front wrapping roller 81, and are arranged diagonally backward from bottom to top, with a limiting structure on them. Two inclined slide blocks 86 are slidably mounted on the two inclined slide rails 83, and two synchronous sprockets 87 are respectively located inside the two inclined slide blocks 86 and are arranged in the left-right direction. Sprockets are provided at both ends of the two wrapping rollers 81, and two synchronous chains 84 are respectively located at the left and right ends of the wrapping rollers 81. The synchronous chains 84 are wound around the corresponding sprockets (sprockets at the same end of the two wrapping rollers 81) and the synchronous sprockets 87, forming a triangle. Two first cylinders 88 are synchronously driven and are used to drive the two horizontal slide blocks 85 to move back and forth respectively. The first cylinders 88 are arranged diagonally forward from bottom to top on the corresponding side (left or right side) of the frame 1, and are hinged to the frame 1 and the horizontal slide blocks 85. Two second cylinders 89 are driven synchronously and are used to drive the two tilting slides 86 to move up and down respectively. The second cylinders 89 are located diagonally from bottom to top and rearward on the corresponding side (left or right side) of the frame 1. When the two wrapping rollers 81 move apart (the front wrapping roller 81 moves forward), the first cylinder 88 extends, the horizontal slide 85 moves forward, the second cylinder 89 extends, and the tilting slide 86 moves upward.

[0054] Example 2

[0055] See Figure 1-2 Example 2 provides an automated bandage preparation device, whose structure is basically the same as that of Example 1, except that the feeding and conveying mechanism in this example includes a conveyor belt and two side plates. The two side plates are arranged side by side, one in front of the bandage strip 4 and the other behind it, and are located above the left and right ends of the conveyor belt, arranged in a left-right direction. The upper end of the front side plate extends upward relative to the rear side plate, and its upper end is located below the rear end of the guide plate 21. The top of the rear side plate has multiple inclined baffles arranged side by side. The inclined baffles are arranged obliquely downward from back to front. The aforementioned structure can prevent the bandage strip 4 from rolling out.

The two inclined slide blocks (86) are slidably mounted on the two horizontal slide rails (82), and are located below the paper wrapping roller (81). The two paper rolls (81) are mounted on two inclined slide rails (83), and two synchronous sprockets (87) are mounted on two inclined slide blocks (86). Sprockets are provided at both ends of the two paper rolls (81), and two synchronous chains (84) are provided at both ends of the paper rolls (81). The synchronous chains (84) are wound around the corresponding sprockets and synchronous sprockets (87) and are triangular in shape. Two first cylinders (88) are driven synchronously and are used to drive the two horizontal slide blocks (85) to move back and forth respectively. The first cylinders (88) are arranged obliquely forward from bottom to top on the corresponding side of the frame (1). Two second cylinders (89) are driven synchronously and are used to drive the two inclined slide blocks (86) to move up and down respectively. The second cylinders (89) are arranged obliquely backward from bottom to top. When the two paper rolls (81) move apart, the horizontal slide blocks (85) move forward and the inclined slide blocks (86) move upward.
