[0093] Step S4, start the drive motor,

[0094] Drive the two groups of first rotating shafts and second rotating shafts to rotate through the drive motor,

[0095] Thereby driving the cutter head arranged on the shaft to rotate, realizing the shearing and crushing action,

[0096] When the cutter head rotates, the cutter comb is fixed at this time,

[0097] Remove the debris on the cutter head through the second arc-shaped end face of the cutter comb,

[0098] At the same time, the first arc-shaped end face of the cutter comb can ensure that the material is smoothly drawn into the crushing area.

[0099] Step S5, place the garbage bag cover in the housing of the crushing device,

[0100] The discarded masks that have been sheared and crushed fall into the garbage bag through the outlet end of the crushing device,

[0101] Start the motor connected to the first pinion and the second pinion,

[0102] Drive the first pinion and the second pinion to move along the two groups of racks with an included angle towards the sealing heater through the motor,

[0103] When moving to the sealing heater,

[0104] At this time, the garbage bag has been closed under the drive of the two pinions,

[0105] Then heat it through the sealing heater to seal it.

[0106] Optionally, step S1 further includes the following steps:

[0107] Step S1.1, place the end of the discarded mask with a nose clip between the gaps of the driving roller and the driven roller of the feeding device through the mask placement table,

[0108] Step S1.2, start the stepping motor, drive the driving roller to rotate through the stepping motor, and then use the friction force to convey the discarded mask with a nose clip to the groove of the mounting seat of the nose clip separation device,

[0109] The stepping motor stops,

[0110] Step S1.3, start the first electric push rod at the same time,

[0111] Drive the punch to move towards the die through the first electric push rod,

[0112] Furthermore, it drives the punching knife arranged on the punch through the fixed die cavity body,

[0113] to punch the masks placed on the mounting seat,

[0114] punch out the nose clips arranged inside the masks,

[0115] Under the action of gravity, the punched-out nose clips automatically fall into the nose clip storage box below.

[0116] To sum up, the beneficial effects of the present invention are as follows:

[0117] (1) The present invention has processes such as collection, nose clip separation, disinfection, pulverization, and recycling. Therefore, during the process of treating waste masks, the waste masks do not need to come into contact with the staff from beginning to end, which can effectively avoid the occurrence of virus cross-infection and improve the safety of the staff.

[0118] (2) Through the stirring rod assembly added in the disinfection device, the present invention can effectively turn the masks, so that each surface of the masks can be fully exposed to the ultraviolet light source, increasing the area of full contact between the masks and the ultraviolet light emitted by the disinfection lamp, enabling each mask to be evenly irradiated by ultraviolet rays, thereby achieving an ideal disinfection effect.

[0153] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Although exemplary embodiments are disclosed in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the concept of the present invention to those skilled in the art.

Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0155] In the present invention, the terms "first", "second", "third" are only used for the purpose of description and cannot be construed as indicating or implying relative importance; the term "plurality" means two or more, unless otherwise clearly defined. Terms such as "installed", "connected", "connected to", "fixed" etc. should all be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0156] As Figure 1-18 shown, this embodiment provides a waste mask recycling machine 100, including a housing 10 and a frame 101 installed inside the housing 10. Considering the assembly, strength and stability, to ensure that the housing can firmly wrap the internal components of the recycling machine and can dissipate heat well, the housing is made of aluminum alloy material, thereby effectively avoiding the influence of external dust, water vapor, vibration, etc. The outer shell is fixed to the frame 10 by means of bolt connection;

[0157] And multiple groups of mounting plates 102 are fixedly connected (any fixed connection methods such as welding, fastening screws, etc.) to the frame 101, and the frame is made of Q235 steel with sufficient strength and durability;

[0158] A mask placement table 20 is provided on the shell 10. In order to facilitate people, especially children, to deliver masks, the mask placement table adopts an inclined design. The mask placement table has a certain inclination angle, which makes it easier for users to deliver masks. A feeding device 80 for delivering masks into the nose clip separation device 40 is correspondingly provided at the outlet end of the mask placement table 20.

[0159] When in use, the mask is placed in the feeding device 80 through the mask placement table 20, and then the mask is transported into the nose clip separation device 40 through the feeding device 80, and the nose clip in the mask is removed through the nose clip separation device 40.

[0160] In order to facilitate wearing, a nose clip is set in the mask to improve the protection. However, when recycling the masks, the metal (nose clip) in the discarded masks cannot be removed separately. Generally, the whole set of masks is crushed by a crushing mechanism, and finally the metal is separated by a screening device. The above method is more complicated and cannot effectively recycle the metal. In order to solve the above technical problems, please refer to Figure 2-5 As shown, the nose clip separation device 40 comprises a first electric push rod 401, the extended end of the electric push rod 401 passes through the upper pad 402 and is fixedly connected to the male mold 406.

[0161] The male die 406 is provided with a guide mechanism 403, and the guide mechanism 403 includes a guide column and a guide sleeve, and is connected to the female die 404 through the guide mechanism 403.

[0162] The nose clip separation device 40 also includes a mounting seat, and the mounting seat is installed on the adjacent mounting plate 102 by means of a fixing connection such as a fastening screw. A discharge spring 407 is provided on the mounting plate 102, and is fixedly connected to the end face of the die 404 away from the guide mechanism by the discharge spring 407.

[0163] Furthermore, in practical applications, it can be learned through multiple simulation experiments that:

[0164] Unloading coefficient K_unloading = 0.02,

[0165] It is known that the punching force F_punch of punching mask nose clip is 100N.

[0166] Unloading force: F_unloading = K_unloading F_impact = 0.02 × 100 = 2N

[0167] Since the mold is small, in order to evenly distribute the elastic force on the mold, 4 unloading springs are set, and the average force of each spring is 0.5N.

[0168] According to the structural dimensions of the mold,

[0169] Mounting seat: L×B×h=180×100×10mm;

[0170] Upper backing plate: L×B×h = 180×100×5 mm;

[0171] Female die: L×B×h = 180×100×10 mm;

[0172] Male die: L×B×h = 180×100×15 mm;

[0173] The selected spring parameters are as follows:

[0174] Spring wire diameter d = 1.5 mm; mean coil diameter D_2 = 5 mm; pitch t = 2 mm; working limit load F_j = 42 N; free height h_0 = 10 mm; number of active coils n = 6; deformation amount h_2 = 5.2 mm under the working limit load; developed length L = 98 mm.

[0175] Furthermore, slots for the punching knife 409 to pass through are provided on both the female die 404 and the mounting seat, and the punching knife 409 is fixedly installed on the male die 406.

[0176] Furthermore, the first electric push rod 401 adopts a medium-sized FD5-A-50 electric push-pull rod.

[0177] In this embodiment, by starting the first electric push rod 401, the male die 406 is driven by the first electric push rod 401 to move towards the female die 404, thereby driving the punching knife 409 arranged on the male die 406 to pass through the stationary slot of the female die, and punching the mask placed on the mounting seat to punch out the nose clip (metal) arranged in the mask. Since a slot corresponding to the upper and lower positions of the female die is provided on the mounting seat, the punched nose clip automatically falls into the lower nose clip storage box 30 under the action of gravity.

[0178] In actual application, due to the relatively thin and light thickness of the waste mask, when the mask passes through the mask placement table and is put into the recycling processor for punching, the position of the mask shifts, thereby causing the probability of punching failure. Please refer to the present invention Figure 1-15 as shown

[0179] The feeding device 80 includes a object support 802, and the object support 802 is fixedly installed on the mounting plate 102 with the mounting seat through fastening bolts. A driving roller 805 is installed on the object support 802 and is driven by a stepping motor 801 installed on the object support 802. A driven roller 804 adjacent to the driving roller 805 is arranged on one side of the driving roller 805, and a gap for placing the mask is provided between the driving roller 805 and the driven roller 804.

[0180] Since the feeding device transports the masks by means of the frictional force between the masks and two sets of rollers (the driving roller and the driven roller), there must be a certain pressing force between the rollers to provide the frictional force to overcome the relative sliding during mask transportation. Please refer to Figure 4 As shown, a leaf spring pressing device 803 is provided between the top end face of the driven roller 804 near the object support 802 and the object support 802. Both ends of the leaf spring pressing device 803 are fixedly connected to the top end face of the driven roller and the inner wall of the object support respectively.

[0181] In this embodiment, during transportation, first, one end of the mask with a nose clip is placed into the gap between the driving roller and the driven roller. Then, by starting the stepping motor 801, the driving roller is driven to rotate by the stepping motor 801, and further, the mask is driven to be transported to the nose clip separating device 40 through the feeding device.

[0182] During the transportation process, when one end of the mask with a nose clip falls onto the mounting seat, at this time, the stepping motor stops. And at this time, the other end of the mask without a nose clip is still between the driving roller and the driven roller and is clamped. Meanwhile, the first electric push rod is started, and the punch 406 is driven to move towards the direction of the die 404 through the first electric push rod 401. Further, the punching knife 409 provided on the punch 406 passes through the fixed die groove body, and punches the mask placed on the mounting seat, punching out the nose clip (metal) provided in the mask. Since a groove body corresponding to the die is provided on the mounting seat, the punched nose clip automatically falls into the lower nose clip storage box 30 under the action of gravity.

[0183] In practical applications, for the purpose of improving practicability, it can also be further improved; the feeding device 80 includes an object support 802, and the object support 802 is fixedly installed on the mounting plate 102 with a mounting seat through fastening bolts. And a driving roller 805 is installed on the object support 802 and is driven by the stepping motor 801 installed on the object support 802. A driven roller 804 adjacent to it is arranged on one side of the driving roller 805. There is a gap for placing the mask between the driving roller 805 and the driven roller 804.

[0184] The driving between the driving roller 805 and the driven roller 804 can also be achieved through the cooperation of synchronous gears. Specifically, it is set as follows: a first synchronous gear is installed on the driving roller driven by the stepping motor 801, and is meshed and connected to a second synchronous gear. The second synchronous gear is installed on the driven roller 804. During application, driven by the stepping motor, the driving roller and the driven roller have the same circumferential speed, and the driving roller and the driven roller are driven in cooperation through synchronous gears (the first synchronous gear and the second synchronous gear).

[0185] Further, the nose clip storage box 30 includes a storage rack 301 installed on the frame 101. The storage rack 301 is used to place the storage box 302, and the top end of the storage box 302 is open;

[0186] And the open end of the storage box is exactly located directly below the die groove body.

[0187] In the embodiment, when there are enough nose clips in the storage box, by opening the nose clip storage box door 303 hinged to the box body, and then pulling the handle of the storage box, the storage box can be pulled out from the storage rack.

[0188] Further, a rough roller 408 is installed on the ear plate of the mounting seat away from the feeding device 80, and the rough roller 408 is driven by a motor 405. A feeding plate with an inclination angle of 135° is arranged on one side of the rough roller 408.

[0189] In this embodiment, after the separation between the nose clip and the mask is completed, the stepping motor 801 is started. The driving roller is driven by the stepping motor 801 to continue rotating, and the mask without a nose clip is conveyed to the opening groove body formed on the mounting seat. And by starting the motor 405, the rough roller 408 is driven to rotate by the motor 405, so as to drive the mask without a nose clip to be conveyed into the collecting device located below the nose clip separating device.

[0190] Further, the collecting device 90 located directly below the discharging port of the nose clip separating device 40 includes a collecting box body 901. The baffle plate of the collecting box body 901 passes through the feeding groove of the adjacent mounting plate and is welded to the bottom end face of the mounting plate close to the rough roller 408;

[0191] The inner wall of the collecting box body 901 is inclined, and the inclination angle is 45°. By providing a slope of 45°, when the discharge plate 904 at the outlet end of the collecting box body 901 is opened, the longitudinal space when the door opens can be effectively saved, and the waste of the internal space of the recycling processor is avoided;

[0192] The outlet end of the collection box body 901 is connected to the discharge plate 904 through a hinge connector 902.

[0193] At least one group of second electric push rods 903 is installed on the outer wall of the collection box body 901, and the extending end of the second electric push rod 903 is fixedly connected to the discharge plate 904.

[0194] Further, the second electric push rod 903 adopts a small FD5-A-48 electric push-pull rod, which requires a rated voltage of 48V, a rated current of 0.8A, a rated load of 3000N, and can be used in an ambient temperature of 12°C to 65°C.

[0195] In this embodiment, when it is necessary to open the discharge plate 904, only the second electric push rod 903 needs to be started, and the discharge plate 904 is driven by the electric push rod 903 to open, so that the materials in the collection box fall into the lower disinfection device 60 intensively.

[0196] Further, the outlet end of the collection device 90 is located above the disinfection device 60. The disinfection device 60 includes a disinfection box body 601 installed on the frame 101, and an installation frame 606 is fixedly installed on the side end face of the disinfection box body 601 through fastening screws, and multiple groups of disinfection lamps 605 are arranged in the installation frame 606.

[0197] Multiple groups of the disinfection lamps 605 are evenly distributed longitudinally along the installation frame 606, and the disinfection lamps 605 adopt ultraviolet C (UVC) with a wavelength of 254 nanometers. When used, the ultraviolet C (UVC) with a wavelength of 254 nanometers irradiates the masks, which can destroy the DNA or RNA structures of viruses and bacteria and make them lose their activity.

[0198] Further, in actual application, in order to prevent the shielding of ultraviolet rays and enable the ultraviolet rays to enter the disinfection box body 601, multiple groups of light-transmitting holes are provided on the disinfection box body 601, and the light-transmitting holes are evenly distributed along the outer wall of the disinfection box body 601.

[0199] In this embodiment, through the cooperation of the disinfection box body with multiple groups of light-transmitting holes and multiple groups of disinfection lamps, the ultraviolet lamp tubes in multiple directions or the more evenly distributed LED ultraviolet light sources irradiate the masks in the collection box from different angles, realizing multi-point irradiation to reduce the shadow effect and improve the disinfection efficiency.

[0200] In this embodiment, during the actual application process, since the masks fall into the inside of the disinfection box body all at once under the action of gravity, the masks are piled up, and only the disinfection lamps cannot disinfect all the masks comprehensively, and there are still dead corners. To solve the above technical problems, please refer to Figure 7-9As shown, a flipping mechanism is provided inside the disinfection box body 601 and is driven by a servo motor 602.

[0201] The flipping mechanism includes a rotating roller 607, and the rotating roller 607 is connected to the drive shaft of the servo motor 602. The flipping mechanism includes a rotating roller 607, and the rotating roller 607 is connected to the drive shaft of the servo motor 602. A plurality of sets of lever components 609 evenly distributed along its axial direction are fixedly connected to the rotating roller 607 by bolts.

[0202] In this embodiment, when the waste masks enter the disinfection device, the infrared sensors built in the disinfection device detect the entry of the masks, and at the same time, the servo motor 602 is started. The lever components 609 arranged on the rotating roller are driven by the servo motor 602 to stir and flip the accumulated waste masks in the disinfection box body, so that each group of masks can be fully disinfected.

[0203] Furthermore, the lever component 609 includes a connecting ring 6091 and a lever 6092 integrally provided with the connecting ring 6091. In actual application, when the adjacent two groups of levers 6092 are spaced 30 mm apart and the angle between the lever 6092 and the rotating roller 607 is 56°, the waste masks in the disinfection box body with a mesh-like hollow can fully receive the ultraviolet irradiation, achieving a better disinfection effect. Therefore, a plurality of sets of threaded holes are axially provided on the rotating roller 607, and the adjacent two groups of threaded holes are spaced 30 mm apart. The depth of the threaded holes is 6 mm. When the connecting ring 6091 is arranged on the rotating roller 607, the threaded holes provided on the rotating roller correspond to the threaded holes of the connecting ring, and then bolts are screwed into the threaded holes for connection to realize the connection between the connecting ring, the rotating roller and the lever.

[0204] Furthermore, the end face of the lever 6091 away from the rotating roller is an arc surface, which can effectively reduce the frictional damage of the lever to the inner wall of the disinfection box body. And the connection part between the lever 6091 and the connecting ring 6092 is rounded, which can effectively avoid the breakage of the lever body and the ring due to stress concentration. The lever is made of rubber material.

[0205] Furthermore, the disinfection box body 601 further includes a discharge plate 604, and the discharge plate 604 is connected to the disinfection box body 601 by a hinge connecting piece.

[0206] The extending end of a third electric push rod 603 is fixedly installed on the discharge plate 604.

[0207] In this embodiment, when discharging is required, the third electric push rod 603 is activated, and the discharge plate 604 is pushed open by the extending end of the third electric push rod 603. At this time, the waste masks that have been disinfected in the disinfection box body fall into the crushing device 70 below through the outlet end of the disinfection box body.

[0208] Further, the crushing device 70 includes a crushing device housing 701,

[0209] The crushing device 70 further includes a driving motor 7081, and a first reduction gear 7082 is installed on the driving shaft of the driving motor 7081. The first reduction gear 7082 is meshed with a second reduction gear 7083, and a second synchronous gear coaxially arranged with it is installed on the gear shaft of the second reduction gear 7083, and its gear shaft is connected to a second rotating shaft 7087 located in the crushing device housing 701;

[0210] The second synchronous gear is meshed with a first synchronous gear 7084, and the gear shaft of the first synchronous gear 7084 is connected to a first rotating shaft 7085 located in the crushing device housing 701.

[0211] Further, the driving motor 7081 adopts a three-phase asynchronous motor of 5IK120GN-S.

[0212] In actual application, since the waste masks without nose clips are of light weight, resulting in poor crushing strength. To solve the above technical problems, please refer to Figure 1-18 As shown, 50 groups of cutter discs 703 are axially installed on the first rotating shaft 7085 and the second rotating shaft 7087. A plurality of groups of crushing teeth are circumferentially arranged on the cutter disc 703. The cross-section of the crushing teeth is arc-shaped. When the angle of the crushing teeth is 45° and the thickness of the cutter disc 703 is 4.5 mm, effective material grasping can be achieved, and the crushing effect of the crushing device can be guaranteed to reach an ideal state. The cutter disc 703 is made of alloy tool steel, so that it has sufficient strength and hardness, can withstand high-frequency impacts and abrasions, and is not easy to break or deform; at the same time, the crushing blades need to have good wear resistance and can maintain sharpness and efficient crushing performance during long-term use.

[0213] Further, a barrier ring 704 is arranged between two adjacent groups of the cutter discs 703, and the arc end face of the cutter disc 703 abuts against the outer wall of the barrier ring 704, thereby effectively preventing the phenomenon of material jamming during the crushing process.

[0214] Further, combing components are respectively arranged on one side of the two rotating shafts, and the combing components include two fixed shafts, and the two fixed shafts are fixedly installed in the crushing device housing 701,

[0215] On two groups of fixed shafts, multiple groups of knife combs 702 are axially installed along their axial directions, and the knife combs 702 are arranged in an interleaved manner with the cutter disc. The knife comb 702 includes a first arc-shaped end face 7021, and the first arc-shaped end face 7021 is located between two groups of the cutter discs 703 and abuts against the side end faces of adjacent two groups of the cutter discs; the knife comb 702 further includes a second arc-shaped end face 7022, and when in the working state, the second arc-shaped end face 7022 abuts against the crushing teeth of the cutter disc; when in the working state, the knife comb is fixed, and at this time, the cutter disc is driven to rotate by the driving motor 7081. At this time, a tearing force is generated between the second arc-shaped end face of the knife comb and the crushing teeth of the cutter disc, so as to ensure that the material is drawn into the crushing area.

[0216] In this embodiment, by providing uniformly distributed knife combs on both sides of the cutter disc, it is possible to prevent the waste masks from being blocked during the crushing process.

[0217] Furthermore, the knife comb further includes a clamping end face 7023, and the clamping end face 7023 abuts against the outer wall of the crushing device housing 701. When the angle R1 of the clamping end face 7023 is 10° - 36.5°, it is more convenient to fix the position of the knife comb.

[0218] Since the mask is mainly composed of materials such as canvas and nylon, in order to achieve a better crushing effect, the diameter D of the cutter disc is 40 mm, the meshing part size between the cutter discs is L = 2.5 mm, and the transmission ratio of the gear reduction drive of the crusher is set to i = 2. Given that the feeding and crushing speed is V = 3.5 m / min, the rotational speeds nI and nII of the first rotating shaft and the second rotating shaft can be calculated according to Equation (6-1).

[0219] n_I = n_II = V / (π(D - 2L)) (6-1)

[0220] In the formula: V - feeding speed;

[0221] D - cutter disc diameter;

[0222] L - cutter disc meshing length.

[0223] n_I = n_II = (3500 mm / min) / (3.14×(40 - 2×2.5)) ≈ 31.847 r / min

[0224] The calculated result can take n_I = n_II = 32 r / min. According to the transmission ratio i = 2, the required rotational speed n_motor (driving motor) of the motor can be calculated according to Equation (6-2).

[0225] n_motor = in_I (6-2)

[0226] n_motor = 2×32 = 64 r / min

[0227] In this embodiment, after the waste masks are disinfected by the disinfection device, they fall into the crushing device below. At this time, the infrared sensor built in the crushing device senses the falling of the waste masks, and at the same time starts the driving motor. The driving motor is used to drive the cutter head to rotate, and then the waste masks located in the housing 701 of the crushing device are completely broken by the cutter head. And the broken waste masks fall into the lower waste material collection bucket 50 under the action of gravity through the outlet end of the housing 701 of the crushing device.

[0228] Further, the waste material collection cylinder 50 includes a rack 502 arranged inside the waste material collection cylinder 50. The rack 502 is arranged around the four sides inside the waste material collection cylinder 50 to form a loop path.

[0229] And a first pinion 503 and a second pinion 506 are respectively meshed and connected to two sets of longitudinal racks 502. One ends of the gear shafts of the two sets of the first pinion 503 and the second pinion 506 are connected to the motor. The other end of the gear shaft of the first pinion 503 is connected to a slide rail 505. The other end of the gear shaft of the second pinion 506 is connected to a moving block 507. And a rectangular groove 504 for the moving block 507 to penetrate is opened in the slide rail 505, so that the moving block 507 can move horizontally along the rectangular groove 504 inside the slide rail 505.

[0230] Further, an arc-shaped groove is provided at the included angle of the waste material collection cylinder 50 (the included angle where the two racks are vertically intersected), and a sealing heater is arranged in the arc-shaped groove. The sealing heater is preferably a ceramic electric heating ring.

[0231] In this embodiment, by placing the garbage bag cover in the housing 701 of the crushing device, and then starting the motors connected to the first pinion and the second pinion respectively, the first pinion and the second pinion are driven by the motors to move towards the sealing heater along the two racks with an included angle of 90 degrees. When moving to the sealing heater, at this time the garbage bag has been closed under the drive of the two pinions, and then it is heated by the sealing heater to seal it.

[0233] Step S1, separating the nose clips in the waste masks;

[0234] Step S1 further includes the following steps:

[0235] Step S1.1, the end of the discarded mask with a nose clip is first placed in the gap between the driving roller 805 and the driven roller 804 of the feeding device 80 through the mask placing table 20.

[0236] Step S1.2, the stepping motor 801 is started, and the driving roller 805 is driven to rotate by the stepping motor 801. Then, the discarded mask with a nose clip is conveyed to the groove of the mounting seat of the nose clip separating device by means of friction. The stepping motor stops.

[0237] Step S1.3, at the same time, the first electric push rod is started. The punch 406 is driven to move towards the direction of the die 404 by the first electric push rod 401. Then, the blanking knife 409 arranged on the punch 406 passes through the fixed die groove body, and the mask placed on the mounting seat is blanked to punch out the nose clip (metal) arranged in the mask. Under the action of gravity, the punched nose clip automatically falls into the lower nose clip storage box 30.

[0238] Step S2, the discarded mask without a nose clip is conveyed into the collection device 90.

[0239] After the blanking knife finishes blanking, the first electric push rod drives the punch to reset.

[0240] The stepping motor 802 is started. The stepping motor 802 drives the driving roller 805 to continue rotating, and then drives the discarded mask without a nose clip to enter the opening groove arranged on the mounting seat.

[0241] At the same time, the motor 405 is started. The rough roller is driven to rotate by the motor 405. Then, the mask without a nose clip is driven to rotate by the rough roller 408. When rotating in a certain direction, at this time, the discarded mask without a nose clip automatically falls into the collection device below the nose clip separating device under the action of gravity.

[0242] Step S3, when the number of masks without a nose clip in the collection device reaches a certain amount, the second electric push rod 903 is started. The baffle 904 is driven to open by the second electric push rod 903. At this time, the masks without a nose clip in the collection device automatically fall into the lower disinfection device 60.

[0243] At this time, the infrared sensor built in the disinfection device 60 senses that the mask has fallen off, activates the servo motor 602, drives the roller 607 to rotate through the servo motor 602, and then drives the roller assembly 609 on the roller 607 to stir the mask in the disinfection device 60. At this time, the disinfection lamps on both sides of the disinfection device pass through the holes on the disinfection device, so as to disinfect the mask in the disinfection device. After the machine operates for a certain period of time to fully disinfect the mask, the third electric push rod 603 is activated, and the discharge plate 604 is pushed through the third electric push rod 603, and then the discharge plate 604 is opened, so that the disinfected mask falls into the crushing device 70;

[0244] Step S4, activate the drive motor 7081, drive the two groups of first rotating shafts 7085 and second rotating shafts 7086 to rotate through the drive motor, and then drive the cutter heads arranged on the shafts to rotate, so as to realize the shearing and crushing action.

[0245] When the cutter head rotates, the cutter comb is fixed at this time. The debris on the cutter head is removed through the second arc end face of the cutter comb, and at the same time, the material can be smoothly drawn into the crushing area through the first arc end face of the cutter comb.

[0246] Step S5, place the garbage bag cover in the housing 701 of the crushing device. The shredded waste masks fall into the garbage bag through the outlet end of the crushing device 70. Finally, by activating the motors connected to the first pinion and the second pinion respectively, the first pinion and the second pinion are driven by the motors to move along the two racks with an included angle of 90 degrees towards the sealing heater. When moving to the sealing heater, the garbage bag has been closed under the drive of the two pinions, and then it is heated by the sealing heater to seal it.
