[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0030] First embodiment

[0031] The sterilizing machine for medicinal film and fabric is a kind of equipment specially used for sterilization in the production of pharmaceutical packaging and medical devices. Its main function is to thoroughly sterilize medicinal film and fabric to ensure that they are not contaminated by microorganisms during production, storage and use. Since medicinal film or fabric is usually rolled, it is difficult to completely penetrate the roll by irradiation and other measures to sterilize the roll, resulting in a low sterilization rate of rolled film and fabric. In order to solve the problem of incomplete sterilization of rolled medicinal film and fabric, and enhance the sterilization effect of medicinal film and fabric, such as Figure 1 - Figure 4 As shown, the present embodiment provides an automatic sterilizing machine for medicinal film material and cloth, which is composed of a sterilization box 1, a feeding conveyor belt 3, a discharging conveyor belt 4, a reeling mechanism 6 and a sterilization mechanism 7. Two sealed discharging doors 2 are respectively arranged at both ends of the sterilization box 1. The sealed discharging doors 2 adopt a double-door structure, which is air-tight and interlocked to ensure that the doors on both sides cannot be opened at the same time, thereby ensuring safe operation. The feeding conveyor belt 3 and the discharging conveyor belt 4 are respectively arranged on one side of the two sealed discharging doors 2. The feeding conveyor belt 3 and the discharging conveyor belt 4 are also provided with a positioning station device for positioning input and output of film materials and cloth coils. The feeding conveyor belt 3 is used to convey unsterilized coils into the sterilization box 1. One end of the discharging conveyor belt 4 is provided with a plastic sealing packaging machine 5 for packaging sterilized film materials and cloth. The sterilized coils are conveyed to the plastic sealing packaging machine 5 for packaging through the discharging conveyor belt 4, thereby effectively avoiding secondary contamination caused by long-term storage and ensuring the sterilization effect.

[0032] The cavity of sterilizer 1 adopts a stainless steel main structure. The inner cavity is made of 316 stainless steel, and the frame and appearance are made of 304 stainless steel. The design adopts arc corners and polishing to improve durability and easy cleaning of sterilization. The seal adopts corrosion-resistant elastic inflatable sealing ring and stainless steel door lock to ensure no leakage during the sterilization process.

[0033] In order to smoothly unfold and then rewind the rolled film material, a more thorough sterilization process can be carried out on the unfolded film material, an unwinding and rewinding mechanism 6 for unfolding and then rewinding the medicinal film material of different specifications is provided on the inner side of the sterilization box 1. The unwinding and rewinding mechanism 6 includes storage brackets 61 respectively fixed to the two ends of the bottom of the sterilization box 1. The storage bracket 61 near one end of the feed conveyor belt 3 is used to store unsterilized film material, and the storage bracket 61 near one end of the discharge conveyor belt 4 is used to store sterilized film material. The two storage brackets 61 are respectively provided with a feeder for conveying the film material. Component 62, two material storage racks 61 are respectively used to store unsterilized membrane material fabrics and sterilized membrane material fabrics. The feeding component 62 near one end of the feed conveyor belt 3 conveys the unsterilized coiled material to the unwinding component 63 for unfolding, and the feeding component 62 near one end of the discharge conveyor belt 4 conveys the sterilized coiled material to the material storage rack 61 at the bottom thereof for temporary storage. An unwinding component 63 for unfolding the membrane material fabric for dust removal and sterilization is provided at one end of the top of the sterilization box 1, and a winding component 64 for winding up the membrane material fabric after dust removal and sterilization is provided at one end of the unwinding component 63.

[0034] The two feeding components 62 respectively include a conveying body 621 fixed at the bottom of the two material storage brackets 61, and the ends of the two conveying bodies 621 that are away from each other are respectively connected to the feeding conveyor belt 3 and the discharging conveyor belt 4, and a dividing turntable 622 is respectively arranged on the top of the two material storage brackets 61, and the axis of the dividing turntable 622 is rotatably connected to a rotating shaft fixed to the sterilization box 1, and three central axes 625 of a circumferential array are respectively arranged at both ends of the dividing turntable 622, and the angle between the two central axes 625 is 120°, and the central axis 625 is arranged as a retractable inflatable axis. Feed push rods 626 are respectively provided on both sides of one end of the conveyor body 621, and the top ends of the two feed push rods 626 are matched with two corresponding center shafts 625 respectively. When the center holes at both ends of the coil are matched with the two center shafts 625 respectively, the center shaft 625 is started to begin to insert into the specified position of the center hole of the film material, and the center shaft 625 expands to fix the coil. A rotating motor 627 with a brake is also provided on the dividing turntable 622 for driving it to rotate. The rotating motor 627 with a brake is used to drive the dividing turntable 622 to rotate and can rotate 120 degrees and then stop stably.

[0035] Three layers of equally spaced movable cross frames 623 are movably arranged on the inner side of the storage bracket 61. The three layers of movable cross frames 623 can be raised and lowered as needed. After the lower layer of coiled materials is used up, the middle layer of movable cross frame 623 can be lowered onto the conveyor body 621, and the upper layer of movable cross frame 623 can be lowered to the middle layer. Four equally spaced positioning blocks 624 are fixed at both ends of the movable cross frame 623, and the two ends of the coiled materials are respectively stuck in two corresponding positioning blocks 624, which can be suitable for coiled materials of various specifications. A plurality of movable blocks arranged at intervals and matched with the positioning blocks 624 are arranged on the conveyor body 621. When the coiled materials match the movable blocks, the conveyor body 621 can drive the coiled materials to move when it is operated, and a driving member for synchronously driving the movable cross frame 623 to rise and fall is fixedly installed on the storage bracket 61.

[0036] The coils to be sterilized are transported to the storage rack 61 through the feed conveyor belt 3. The storage rack 61 can store a batch of coils. When the coil sterilization begins, the driving member is first driven to drive the lower movable cross frame 623 to move downward, and the movable cross frame 623 moves to the conveyor body 621. The conveyor body 621 transports the coils to the top of the feed push rod 626. The feed push rod 626 pushes the coils to move upward to the two central shafts 625 at the bottom of the dividing turntable 622. At the same time, the central shaft 625 is started to start inserting into the specified position of the center hole of the membrane material. The central shaft 625 expands and fixes the coil, and then the dividing turntable 622 is driven to rotate 120 degrees by the rotating motor 627 with a brake to fix another coil, thereby fixing three coils on the dividing turntable one after another.

[0037] Second embodiment

[0038] In order to make the unrolling and rewinding of the rolled membrane fabric smoother, the membrane fabric is thoroughly sterilized during the unrolling process, such as Figure 3As shown, in this embodiment, the implementation method is specifically that the unwinding component 63 includes an unwinding roller shaft 631 arranged on a dividing turntable 622 near one end of the feed conveyor belt 3, one end of the unwinding roller shaft 631 is provided with a brake cylinder 632 fixed to the dividing turntable 622, the output shaft of the brake cylinder 632 is hingedly provided with an L-shaped rotating bracket 633, and the middle part of the L-shaped rotating bracket 633 is rotatably provided with a limit shaft fixed to the dividing turntable 622, one end of the unwinding roller shaft 631 is fixed with a brake disc 634, and the outer side of the brake disc 634 is movable A brake belt 635 is movably provided with one end fixed to the dividing turntable 622, and the other end of the brake belt 635 is movably hinged to one end of the L-shaped rotating bracket 633. By starting the brake cylinder 632, the output shaft of the brake cylinder 632 pulls one end of the L-shaped rotating bracket 633 to move, and the L-shaped rotating bracket 633 rotates a certain angle around the limiting axis, and the other end of the L-shaped rotating bracket 633 pulls the brake belt 635. The brake belt 635 wraps around the brake disc 634 to stop the rotation of the brake disc 634, thereby controlling the stop of the unwinding roller shaft 631.

[0039] The unwinding assembly 63 also includes a tension control assembly 636 arranged on one side of the unwinding roller shaft 631 for adjusting the tension of the membrane cloth. The tension control assembly 636 includes four fixed rollers 6361 arranged on one side of the top of the unwinding roller shaft 631 and rotated with the sterilization box 1 through bearings. A floating roller 6362 is arranged at the bottom of one of the fixed rollers 6361, and the membrane cloth is respectively wound around the four fixed rollers 6361 and the floating roller 6362, and a driving member for driving the floating roller 6362 to lift and lower the floating roller 6362 and fixed to the sterilization box 1 is arranged at the bottom of the floating roller 6362. A tension detection probe 6363 fixed to the sterilization box 1 is arranged on one side of the floating roller 6362. The tension detection probe 6363 is used to monitor the stroke position of the floating roller 6362 for adjusting the tightness. When the floating roller 6362 moves to the maximum adjustment stroke, the rotation of the unwinding roller shaft 631 is stopped by starting the brake cylinder 632. At this time, the floating roller 6362 moves upward and begins to release the coil until it leaves the monitoring range of the tension detection probe 6363. The brake cylinder 632 is started again to relax the unwinding roller shaft 631, and the unwinding roller shaft 631 starts to start, thereby making the unwinding roller shaft 631 output at a uniform speed. This cycle is repeated to complete the tensioning of the coil.

[0040] The winding assembly 64 includes a winding roller shaft 641 arranged on a dividing turntable 622 near one end of the discharge conveyor belt 4. The winding roller shaft 641 is the main shaft for winding the film cloth. A servo motor 642 fixed to the dividing turntable 622 is arranged at one end of the winding roller shaft 641. The output shaft of the servo motor 642 is connected to the winding roller shaft 641 through a belt. The balance, accuracy and stability of the winding roller shaft 641 can be ensured during the winding process. A correction device is arranged on two fixed rollers 6361 near one side of the winding roller shaft 641. The correction device includes a correction actuator, a correction sensor and a correction controller. The correction sensor is provided with a monitoring probe on the winding side to send a signal to the correction controller. After the controller detects that the coil has position drift, the position of the coil is corrected by the correction actuator according to the pre-set program instructions. The correction actuator includes a cylinder, a servo motor 642 and other transmission devices. The drive stroke is set in a strict proportional relationship with the coil offset to ensure that the coil is neat after winding.

[0041] A sealed double door 8 is hingedly provided on one side of the sterilization box 1, and two symmetrically arranged operating gloves 9 for maintaining the sterilization process are installed on the sealed double door 8. The sealed double door 8 is also provided with 10mm tempered glass as an observation window. At the same time, two sterile operating gloves 9 are installed on the sealed double door 8 to facilitate the connection of sterilized materials and troubleshooting during the sterilization process. Before the coiled material is sterilized, the membrane cloth on the unwinding roller shaft 631 is manually wound around the four fixed rollers 6361 and the floating roller 6362 respectively through the operating gloves 9, and finally wound around the winding roller shaft 641, so as to complete the connection between the unwinding roller shaft 631 and the winding roller shaft 641.

[0042] The accumulated tightness formed by the speed difference between the unwinding roller 631 and the winding roller 641 is used to control the tension of the membrane cloth by moving the floating roller 6362 up and down. The unwinding roller will loosen due to the inertia after starting. The tension of the membrane cloth is monitored by the tension detection probe 6363, and then the corresponding tension force is output to offset the looseness caused by the starting inertia, so as to control the unwinding roller to output at a uniform speed.

[0043] When the winding roller 641 has wound up the sterilized film material, the dividing turntable 622 near one end of the discharge conveyor belt 4 drives the coil to rotate to the top of the feed push rod 626, and the feed push rod 626 drives the coil to move downward, and the sterilized coil falls onto the conveyor body 621, and is driven by the conveyor body 621 to the upper movable horizontal frame 623 in the storage bracket 61. After the upper movable horizontal frame 623 is filled with coils, the upper movable horizontal frame 623 is pushed to move upward, so that the middle movable horizontal frame 623 cooperates with the conveyor body 621, so that the sterilized coil is taken off and transferred to the storage bracket 61 in turn. After a batch of sterilization is completed, the sealed discharge door 2 is opened and conveyed to the plastic sealing packaging machine 5 through the discharge conveyor belt 4 for packaging.

[0044] Third embodiment

[0045] In order to more thoroughly remove the bacteria on the membrane fabric and completely remove the residual sterilization gas in the sterilization chamber, such as Figure 2 As shown, in this embodiment, the sterilization mechanism 7 is arranged on the sterilization box 1 for dust removal and sterilization of the unfolded membrane material fabric. The specific implementation method is that the sterilization mechanism 7 includes a vacuum sterilization system 71 fixedly installed on the top of the sterilization box 1, an ion fan dust removal device 72, a control monitoring system and a ventilation device 73. The vacuum sterilization system 71, the ion fan dust removal device 72, the control monitoring system and the ventilation device 73 are all prior arts and will not be described in detail in this application.

[0046] The vacuum sterilization system 71 is used to sterilize the inside of the sterilization box 1 under a vacuum environment. The vacuum sterilization system 71 includes a vacuum pump, a sterilization device, a concentration probe, a sterilizing filter, and a control and monitoring system. First, after the material storage rack of the feeding mechanism has finished storing materials, the feeding port of the sterilization box is closed, and sterilization is performed before unwinding. Before sterilization, it is necessary to enter and evacuate to ensure that the vacuum degree reaches above -0.08MPa, and the air tightness of the box is tested to meet the vacuum requirements. At the same time, hydrogen peroxide or ethylene oxide is injected for sterilization. When the gas concentration reaches the set value, the concentration probe is used to monitor the concentration and distribution uniformity of the sterilizing gas to meet the requirements, and the loading and unwinding program is started. When the film cloth of the storage rack is completely rolled, that is, the sterilization of the film cloth is completed, the sterilizing filter is opened to empty it, and the vacuum is continued after emptying. This cycle is repeated many times to ensure that there is no residual sterilizing gas in the box. Only then can the discharge conveying port be opened and transferred to the packaging area, so that the sterilization operation of a single batch is completed.

[0047] The ion fan dust removal device 72 is used to remove dust and bacteria on the film material. As a dust removal and sterilization purification equipment, it removes dust, bacteria and other particles on the film material by generating ion wind with charged characteristics to absorb and neutralize charged particles, thereby providing cleaner and safer medicinal film materials.

[0048] The control and monitoring system is used to start the unwinding and winding mechanism 6, and turn on the ion fan dust removal device 72 during the unwinding and winding process of the membrane cloth. The control and monitoring system monitors the concentration of the sterilization gas injected through the temperature and humidity concentration sensor, and starts the unwinding and winding device after reaching the sterilization concentration. The ion fan dust removal device 72 is turned on during the unwinding and winding process, and a ventilation device 73 is set at the reflection port of the ion wind dust removal.

[0049] The ventilation device 73 is used to ventilate the sterilization box 1. The ventilation device 73 includes an adsorption device, a collecting barrel, a clean filter and a residual exhaust system. The adsorption device adsorbs the neutralized dust particles and enters the collecting barrel. A clean filter is arranged in the middle of the collecting barrel. The sterilized gas after filtration re-enters the cavity of the sterilization box 1, and the dust removal and sterilization process is circulated in this way. After the dust removal and sterilization of a batch of coils are completed, the residual exhaust system is automatically turned on. The residual exhaust system is composed of a vacuum system and a respirator. When the residual sterilization gas in the sterilization chamber is removed, the vacuum is turned on and automatically extracted. After the extraction is completed, the respirator is opened, and clean air enters the sterilization chamber through the respirator. This method is repeated three times to remove the residual sterilization gas in the sterilization chamber.
