Description

Technical Field

[0001] The present invention relates to the technical field of presses, and more particularly to an automatic press for producing medical bandages. Background Art

[0002] Band-Aids have certain bactericidal and hemostatic effects, mainly to prevent dirty bacteria and the like from contaminating wounds. They are one of the most commonly used surgical items in our lives, and are mainly composed of dry adhesive tape, medicated absorbent pads, and isolating permeable membranes. In the automated production process of Band-Aids, an automatic press is used. This equipment is mainly used for the key processes of Band-Aid molding and bonding. The automatic press consists of a hydraulic cylinder, a pressure head, a base, and a control box. When the automatic press is pressing, the hydraulic cylinder drives the pressure head down to press down the Band-Aid, thereby bonding the multiple layers of fabric of the Band-Aid together. However, the current automatic press can only press once in a single lifting process, and cannot press and shape the Band-Aid when the pressure head rises, thereby reducing the efficiency of Band-Aid molding.

[0014] Technical effects and advantages of the present invention: 1. The present invention provides a transmission member and a pressure column. When the hydraulic cylinder in the press body is activated, the pressure rod is driven by the hydraulic cylinder to descend, so that the pressure head contacts the pressing assembly and presses it. The band-aid is pressed and formed by the pressing assembly. After the pressing is completed, the pressure head rises and drives the installation kit to rise at the same time. The transmission member is rotated under the drive of the slide rod, so that the transmission connecting frame gradually descends. The pressure column is driven to descend and contact the pressing assembly through the transmission connecting frame, so that the pressing assembly presses the band-aid again. In this way, the band-aid can be pressed and formed while the pressure head is rising, thereby making full use of the force of the pressure head rising process, avoiding energy waste and improving the efficiency of band-aid forming. 2. The present invention provides a pressing base and a pressing plate. When the pressure head or the re-pressing assembly descends and applies pressure to the pressing plate, the pressing plate descends and contacts the pressing base, thereby pressing and molding the bandage on the top of the pressing base. At the same time, when the pressure head or the re-pressing assembly rises and loses contact with the pressing plate, the pressing plate can rise and reset under the tension of the spring. When pressure is applied to the pressing plate next time, the bandage on the top of the pressing base can be pressed and molded again. Compared with the pressure head of a traditional press, the pressing plate and the pressure head of the present application are of a separate design, thereby being able to complete the double pressing and molding of the bandage in combination with the re-pressing assembly during the process of the pressure head rising and falling. 3. The present invention sets a fixed plug plate. When installing after replacing the pressing plate, the circular end of the connecting sleeve is sleeved on the outer side of the movable positioning column, and the pressing plate is pressed down to make the fixed plug plate coincide with the transverse groove. The fixed plug plate is driven to be inserted into the inner side of the transverse groove by the contraction of the limiting spring piece, so that the pressing plate is connected to multiple movable positioning columns to complete the installation. Since the connection with multiple movable positioning columns is completed at the same time and the transverse grooves are set at the same height, the pressing plate can be kept in a horizontal state after installation, so as to avoid the pressing plate being tilted during installation, which makes it impossible to press the band-aid into shape. The disassembly and assembly process is simple and convenient, which greatly facilitates the disassembly and maintenance of the pressing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Refer to the instruction manual Figure 1As shown, an automatic press for producing medical bandages according to an embodiment of the present invention includes a press body 1, a pressure rod 2 is provided inside the press body 1, a hydraulic cylinder is installed inside the press body 1, the pressure rod 2 is driven to rise and fall by the hydraulic cylinder, a pressure head 4 is fixedly connected to the bottom of the pressure rod 2, and conveying devices 30 are provided on both sides of the press body 1, a re-pressing component, the re-pressing component is used to press and form the bandage when the pressure rod 2 rises, the re-pressing component is respectively connected to the press body 1 and the pressure rod 2, a pressing component, the pressing component is used to press and form the bandage, the pressing component is connected to the press body 1, an installation component, the installation component is used to improve the efficiency of disassembly and positioning of the pressing component, the installation component is connected to the pressing component, the re-pressing component includes an installation kit 3 fixedly sleeved on the outside of the pressure rod 2, the installation kit 3 is two identical arc-shaped structures connected by bolts The cam 7 is connected to the left of the cam 7 and the right of the cam 7 is connected to the right of the cam 7. The cam 7 is connected to the right of the cam 7 and the left of the cam 7 is connected to the right of the cam 7.

[0019] It should be noted that, when producing the band-aid, the band-aid to be pressed and formed is conveyed to the inner side of the pressing assembly by the conveying device 30, and the hydraulic cylinder in the press body 1 is started to drive the pressure rod 2 to descend, so that the pressure head 4 is brought into contact with the pressing assembly and pressed, and the band-aid is pressed and formed by the pressing assembly. At the same time, after the pressure rod 2 rises and loses contact with the pressing assembly, the band-aid that has been pressed leaves the pressing assembly, and the band-aid to be pressed continues to enter the pressing assembly. At the same time, the pressure rod 2 is in a state of continuing to rise, and at the same time drives the installation kit 3 to rise, and the transmission member 8 is rotated under the drive of the slide rod 5. At the same time, when the transmission member 8 rotates and the installation kit 3 rises, the slide rod 5 slides at one end of the transmission member 8, so as to The distance between the transmission member 8 and the installation kit 3 is applicable. When the transmission member 8 rotates, the transmission connecting frame 9 will be prompted to gradually descend, and the transmission connecting frame 9 will drive the pressure column 10 to descend and contact the pressing assembly, so that the pressing assembly can press and form the Band-Aid again. In this way, the pressing and forming of the Band-Aid can be completed during the rising process of the pressure head 4, thereby making full use of the force of the rising process of the pressure head 4, avoiding energy waste and improving the efficiency of Band-Aid forming. It should be noted that when the pressure rod 2 drives the pressure head 4 to descend and prompts the pressure column 10 to separate from the pressing assembly, the Band-Aid continues to be conveyed, so that the Band-Aid can be conveyed before the pressure head 4 or the transmission connecting frame 9 contacts the pressing assembly, so that the present application can be automatically operated when integrated into the Band-Aid production line.

[0020] Further, such as Figure 3 As shown, the pressing assembly includes a fixed base 11 slidably connected to the inside of the press body 1, and a fixed rotating rod 12 is threadedly connected to one side of the press body 1. The fixed rotating rod 12 is in conflict with the fixed base 11. By tightening the fixed rotating rods 12 on both sides and contacting the fixed base 11, the friction of the fixed base 11 is greatly increased, and the fixed base 11 is fixed to the inner side of the press body 1. The top of the fixed base 11 is fixedly connected to the pressing base 13. The conveying device 30 (such as a roller conveyor) is used to sequentially stack and convey the multiple layers of fabric of the band-aid to the top of the pressing base 13 to complete the subsequent pressing and forming. The inside of the pressing base 13 is fixedly connected to the fixed positioning column 14, and the top of the fixed positioning column 14 is slidably sleeved with a movable positioning column 15. The top of the movable positioning column 15 is provided with a transverse groove 16, and the transverse groove 16 cooperates with the mounting assembly to achieve the fixation of the pressing assembly. The top of the pressing base 13 is provided with a spring 17, which is sleeved on the outside of the fixed positioning column 14 and the movable positioning column 15.

[0021] The outer side of the movable positioning column 15 is sleeved with a pressing plate 18, and the pressing plate 18 is in contact with the pressing base 13 to press the band-aid into shape. The spring 17 is arranged at the bottom of the pressing plate 18, and the fixed positioning column 14 cooperates with the movable positioning column 15 to achieve stretching and contraction so that the pressing plate 18 and the pressing base 13 can approach or move away from each other. At the same time, under the tensile force of the spring 17, the pressing plate 18 can always tend to be away from the pressing base 13. The top of the pressing plate 18 is fixedly connected to a downward pressing kit 27, and the top of the pressing plate 18 is fixedly connected to a limiting sleeve 28. The bottom of the limiting sleeve 28 and the downward pressing kit 27 are made of rubber, so that when in contact with the pressure column 10 and the pressure head 4 When in contact, the pressing plate 18 is protected to avoid mutual damage due to long-term high-voltage contact or the presence of impurities. The pressure column 10 is slidably connected to the inner side of the limiting sleeve 28, and the pressure column 10 is limited by the limiting sleeve 28 so that the pressure column 10 slides vertically on the inner side of the limiting sleeve 28. A through groove 29 is provided on the outer side of the limiting sleeve 28. Since the transmission connecting frame 9 and the transmission member 8 and the pressure column 10 are all connected in a rotating manner and are rotating, the pressure column 10 slides vertically. Therefore, when the transmission member 8 rotates to cause the transmission connecting frame 9 to descend, the transmission connecting frame 9 will be in an inclined state. At this time, the transmission connecting frame 9 can pass through the through groove 29 to avoid collision with the limiting sleeve 28.

[0022] It should be noted that when the pressure head 4 or the re-pressing assembly descends and applies pressure to the pressing plate 18, the pressing plate 18 descends, and at the same time, the movable positioning column 15 descends and the spring 17 contracts. When the pressing plate 18 contacts the pressing base 13, the Band-Aid on the top of the pressing base 13 can be pressed and formed. At the same time, when the pressure head 4 or the re-pressing assembly rises and loses contact with the pressing plate 18, the pressing plate 18 can rise and reset under the tensile action of the spring 17, so that the Band-Aid can continue to be transported. At the same time, the next time the pressure head 4 or the re-pressing assembly descends and applies pressure to the pressing plate 18, the Band-Aid on the top of the pressing base 13 can be pressed and formed again. Compared with the pressure head of a traditional press, the pressing plate 18 and the pressure head 4 of this application are of separate design, so that the re-pressing assembly can be combined to complete the two pressing and forming of the Band-Aid during the process of the pressure head 4 rising and falling.

[0023] Further, such as Figure 3As shown, the installation assembly includes a connecting sleeve 19 fixedly connected to the top of the pressing plate 18, the connecting sleeve 19 is sleeved on the outside of the movable positioning column 15, and one end of the connecting sleeve 19 is annular so that it can be sleeved on the outside of the movable positioning column 15. The interior of the connecting sleeve 19 is slidably connected with a fixed plug-in plate 20, which is inserted into the inner side of the transverse groove 16. The fixing of the pressing plate 18 can be completed by cooperating with the transverse groove 16. One side of the fixed plug-in plate 20 is fixedly connected to a limiting spring piece 21. The limiting spring piece 21 is an elastic structure. The fixed plug-in plate 20 is driven to slide by the stretching and contraction of the limiting spring piece 21. The positioning spring piece 21 is fixedly connected to the inner side of the connecting sleeve 19, and the end of the fixed plug plate 20 away from the limiting spring piece 21 is fixedly connected to the ring 22. The top of the pressing plate 18 is rotatably connected to the shaft column 23, and the outer side of the shaft column 23 is fixedly connected to the arc rod 24. The arc rod 24 is slidably connected to the inner side of the ring 22. The arc rod 24 cooperates with the ring 22, so that when the shaft column 23 rotates, the arc rod 24 pulls the ring 22 to drive the fixed plug plate 20 to slide. The top of the shaft column 23 is fixedly connected to the top cover 25, and the top of the top cover 25 is rotatably connected to the pull handle 26. By pulling the two pull handles 26 at the same time, the pressing plate 18 is conveniently transferred.

[0024] It should be noted that, since some band-aids need to be punched with ventilation holes, the pressing plate 18 needs to be replaced at this time to complete the punching operation of the band-aid when the band-aid is pressed. When replacing the pressing plate 18, the pull handles 26 on both sides are flipped to a vertical state, and the pull handles 26 are rotated to rotate the shaft column 23, so that the contact between the arc rod 24 and the ring 22 causes the multiple fixed plug plates 20 to gradually move toward the direction of the shaft column 23. When the fixed plug plates 20 are displaced, they gradually slide out from the inner side of the transverse groove 16, and the limiting spring piece 21 is stretched. When the fixed plug plate 20 is completely separated from the inner side of the transverse groove 16, the pressing plate 18 can be separated from the multiple movable positioning columns 15 by pulling the pull handle 26 upward. At this time, the pressing plate 18 that can punch ventilation holes can be replaced.

[0025] When the pressing plate 18 is installed, the shaft column 23 is rotated to force the fixed plug plate 20 to remain close to the shaft column 23, that is, the fixed plug plate 20 is away from the circular end of the connecting sleeve 19, and at the same time, the circular end of the connecting sleeve 19 is sleeved on the outer side of the movable positioning column 15, and the pressing plate 18 is pressed down to make the fixed plug plate 20 coincide with the transverse groove 16. After the fixed plug plate 20 coincides with the transverse groove 16, the shaft column 23 is flipped, so that the collar 22 and the fixed plug plate 20 lose the pull of the arc rod 24. At this time, the limiting spring piece 21 contracts and drives the fixed plug plate 20 to insert into the inner side of the transverse groove 16, so that the pressing plate 18 and multiple movable positioning columns are aligned. The connection is completed between the positioning columns 15, and since the connection is completed with multiple movable positioning columns 15 at the same time, and the transverse grooves 16 are set at the same height, the pressing plate 18 can be kept in a horizontal state after installation is completed to avoid the pressing plate 18 from tilting during installation. The disassembly and assembly process is simple and convenient, which greatly facilitates the disassembly and maintenance of the pressing plate 18. At the same time, when the pressing base 13 needs to be disassembled, it is only necessary to loosen the fixed rotating rods 12 on both sides to pull the pressing base 13 out from the inside of the press body 1. The disassembly and assembly method is also simple and convenient, which makes it easy to disassemble the pressing base 13 due to needs or maintenance.
