Description

Technical Field

[0001] The utility model relates to the technical field of mask machines, in particular to a production device for cup-shaped mask bodies. Background Art

[0002] The applicant applied for a Chinese patent document with the application number 202222215127.8 on August 22, 2022, which discloses a production device for cup-shaped mask bodies, including a mask transfer and covering device, a mask forming line, and a cup-shaped mask body forming line. A mask side edge folding device is provided at the end of the mask forming line. The cup-shaped mask body forming line includes a frame, a cloth feeding device, a cup-shaped cover body forming machine, a mask covering station, and a combined forming machine. The cup-shaped cover body forming machine forms a cup-shaped cover body on the cloth. The mask side edge folding device folds the edge of the mask upward. The mask transfer and covering device covers the mask on the cup-shaped cover body. The combined forming machine connects the mask and the cup-shaped cover body and forms a cup-shaped mask body. The mask forming line and the cup-shaped mask body forming line in this patent document are arranged side by side, resulting in an insufficiently compact structure, a large volume, and a large floor area.

[0003] In addition, the applicant applied for a Chinese patent document with the application number 202410522491.X on April 28, 2024, which discloses a cup-shaped mask machine, including a machine table, a circulating conveying mechanism, a plurality of processing and forming carriers, a third cloth cover body forming device, a first cloth feeding mechanism, a second cloth feeding mechanism, a first cloth cover body forming mechanism, a second cloth cover body forming and laminating mechanism, a laminating station, an ultrasonic welding mechanism, a sponge strip pasting device, an outer shape cutting mechanism, a waste material discharging mechanism, and a cover body discharging device. A flipping and loading device is provided between the third cloth cover body forming device and the laminating station. A cutting mechanism is provided on the feeding side of the second cloth cover body forming and laminating mechanism; the processing and forming carrier is provided with a processing and forming through hole and a plurality of positioning columns distributed outside the processing and forming through hole. Although this patent document circulates and conveys the processing and forming carriers through the circulating conveying mechanism, and each processing mechanism can be distributed around the circulating conveying mechanism, shortening the length of the machine and making the structure of the machine compact and occupying less space, the outer shape cutting mechanism directly cuts the outer shape of the laminated cover body carried by the processing and forming carrier to form a cup-shaped mask body. Since there may be processing errors or / and assembly errors and other errors in each processing and forming carrier, it is equivalent that the cutting bottom die for each laminated cover body during outer shape cutting is different. Therefore, directly cutting the outer shape of the laminated cover body on the processing and forming carrier by the outer shape cutting mechanism is difficult to ensure the accuracy and consistency of the cup-shaped mask body after cutting and forming.

[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Utility Model

The sponge strip attaching device attaches the sponge strip to the initially formed cup-shaped mask body to form the final cup-shaped mask body. The demolding mechanism takes out the cup-shaped mask body from the processing and forming die to realize the demolding of the cup-shaped mask body. Then, the flipping device flips and feeds the cup-shaped mask body picked up by the demolding mechanism to the receiving station of the feeding mechanism, which not only realizes the transfer of the cup-shaped mask body but also changes the cup-shaped mask body from the state with the opening facing upward to the state with the opening facing downward. The feeding mechanism intermittently conveys the cup-shaped mask body, so that the outer shape cutting and forming device cuts the outer shape of the cup-shaped mask body at the outer shape cutting and forming station to cut and form the cup-shaped mask main body on the cup-shaped mask body. The blanking device blanks the cup-shaped mask main body at the blanking station to the required position, and the feeding mechanism outputs the waste generated by the outer shape cutting. The present utility model adopts the annular circulating conveying method when producing and forming the cup-shaped mask body, making the structural layout of the equipment compact, shortening the length of the equipment, having a small floor area, and arranging the outer shape cutting and forming device outside the annular circulating conveying mechanism to cut the outer shape of the cup-shaped mask body, avoiding directly cutting the outer shape of the cup-shaped mask body carried by each processing and forming die, and not affecting the accuracy and quality of the outer shape cutting due to possible processing errors or / and assembly errors and other errors in each processing and forming die.

Detailed implementation manners

[0033] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present utility model.

The turning and feeding device 11 is used to turn and feed the second cup-shaped mask body formed by the second cup-shaped mask body forming machine 4 onto the first cup-shaped mask body carried by the processing and forming mold 3. The demolding mechanism 10 is located at one end of the circular circulating conveying mechanism 2 close to the feeding mechanism 5, and the demolding mechanism 10 is used to take out the cup-shaped mask body carried by the processing and forming mold 3. A receiving station 12, a contour cutting and forming station 13, and a blanking station 14 are arranged in sequence in the feeding direction of the feeding mechanism 5. A turning device 15 is arranged between the feeding mechanism 5 and the demolding mechanism 10, and the turning device 15 is used to turn the cup-shaped mask body picked up by the demolding mechanism 10 onto the receiving station 12 of the feeding mechanism 5. The machine table 1 is equipped with a contour cutting and forming device 16 located at the contour cutting and forming station 13 and a blanking device 17 movably arranged above the blanking station 14. The contour cutting and forming device 16 is used to cut and form a cup-shaped mask body on the cup-shaped mask body; specifically, the machine table 1 is assembled from metal profiles.

[0035] In practical applications, the second cup-shaped cover forming machine 4 forms the second cup-shaped cover, and the first cup-shaped cover forming machine 6 forms the first cup-shaped cover and supplies it to the processing and forming die 3. The circulating conveying part of the annular circulating conveying mechanism 2 drives a plurality of processing and forming dies 3 to move intermittently in a cycle. When the processing and forming die 3 carrying the first cup-shaped cover moves to the stacking and pressing device 7, the flipping and feeding device 11 flips the second cup-shaped cover onto the first cup-shaped cover carried by the processing and forming die 3, so that the second cup-shaped cover is stacked on the first cup-shaped cover. Then, the stacking and pressing device 7 presses the stacked second cup-shaped cover and the first cup-shaped cover together. As the processing and forming die 3 moves, the ultrasonic welding device 8 welds the stacked second cup-shaped cover and the first cup-shaped cover together to initially form the cup-shaped mask body. The sponge strip pasting device 9 pastes the sponge strip inside the initially formed cup-shaped mask body to form the final cup-shaped mask body. The demolding mechanism 10 takes out the cup-shaped mask body from the processing and forming die 3 to realize the demolding of the cup-shaped mask body. Then, the flipping device 15 flips and feeds the cup-shaped mask body picked up by the demolding mechanism 10 to the receiving station 12 of the feeding mechanism 5, which not only realizes the transfer of the cup-shaped mask body but also changes the cup-shaped mask body from the state with the opening facing upward to the state with the opening facing downward. The feeding mechanism 5 conveys the cup-shaped mask body intermittently, so that the outer shape cutting and forming device 16 cuts the outer shape of the cup-shaped mask body at the outer shape cutting and forming station 13 to cut and form the cup-shaped mask main body on the cup-shaped mask body. The blanking device 17 blanks the cup-shaped mask main body at the blanking station 14 to the required position, and the feeding mechanism 5 outputs the waste generated by the outer shape cutting. The utility model adopts the annular circulating conveying method when producing and forming the cup-shaped mask body, making the structural layout of the equipment compact, shortening the length of the equipment, having a small floor area, and arranging the outer shape cutting and forming device 16 outside the annular circulating conveying mechanism 2 to cut the outer shape of the cup-shaped mask body, avoiding directly cutting the outer shape of the cup-shaped mask body carried by each processing and forming die 3, and not affecting the accuracy and quality of the outer shape cutting due to possible processing errors or / and assembly errors and other errors of each processing and forming die 3.

[0036] In this embodiment, the production equipment for the cup-shaped mask body further includes an upper nose pad device 18 installed on the machine table 1 and disposed on the periphery of the annular circulating conveyor mechanism 2. The upper nose pad device 18 is located between the laminating and pressing device 7 and the ultrasonic welding device 8. In practical applications, the upper nose pad device 18 supplies nose pads and conveys the nose pads to the first cup-shaped mask body and the second cup-shaped mask body after lamination and pressing. The ultrasonic welding device 8 welds the first cup-shaped mask body, the second cup-shaped mask body, and the nose pads together. The utility model integrates the sponge strip pasting device 9 and the upper nose pad device 18 on one device. During the production process, according to different types of cup-shaped mask bodies to be produced, either the sponge strip pasting device 9 or the upper nose pad device 18 is selected for use, serving two purposes with one object. When the sponge strip pasting device 9 is working, the upper nose pad device 18 is not working. When the upper nose pad device 18 is working, the sponge strip pasting device 9 is not working, so as to meet the needs of users for producing different types of cup-shaped mask bodies, and it has strong practicability.

[0037] In this embodiment, the upper nose pad device 18 includes a nose pad cutting and forming mechanism 19 installed on the machine table 1, a nose pad coil rack 20 installed on the machine table 1 and erected above the nose pad cutting and forming mechanism 19, and an upper nose pad manipulator 21 movably arranged between the discharge end of the nose pad cutting and forming mechanism 19 and the processing and forming die 3. The nose pad coil rack 20 is used to supply the nose pad tape to the nose pad cutting and forming mechanism 19. The nose pad cutting and forming mechanism 19 is used to cut and form the nose pad tape into nose pads. The upper nose pad manipulator 21 is used to pick up the nose pads and place them on the first cup-shaped mask body and the second cup-shaped mask body after lamination and pressing carried by the processing and forming die 3.

[0038] In practical applications, the nose pad coil is installed on the nose pad coil rack 20. The nose pad tape of the nose pad coil passes through the nose pad cutting and forming mechanism 19. The nose pad cutting and forming mechanism 19 cuts the nose pad tape to cut and form individual nose pads. Then, the upper nose pad manipulator 21 feeds the nose pads onto the first cup-shaped mask body and the second cup-shaped mask body after lamination and pressing, so as to realize the automatic feeding of the nose pads.

[0039] In this embodiment, the nose pad cutting and forming mechanism 19 includes a seat body 22 installed on the machine table 1, and a nose pad tape guide roller 23, a roller pressing and conveying module 24, a roller cutting module 25, and a conveyor belt module 75 that are sequentially arranged from outside to inside and rotatably arranged on the seat body 22. The seat body 22 is equipped with a rotation driving mechanism 26 for driving the roller pressing and conveying module 24, the roller cutting module 25, and the conveyor belt module 75 to rotate. The roller pressing and conveying module 24 is used to convey the nose pad tape. The roller cutting module 25 is used to roller cut the nose pads on the moving nose pad tape. The conveyor belt module 75 is used to output the nose pads. The upper nose pad manipulator 21 is used to pick up the nose pads on the conveyor belt module 75.

[0040] In practical applications, the nose pad material belt of the nose pad material roll passes through the roller press conveying module 24 and the roller cutting module 25 in sequence after passing around the nose pad material belt guide roller 23. The roller press conveying module 24 conveys the nose pad material belt to make it move. During the movement of the nose pad material belt, the roller cutting module 25 performs roller cutting on the nose pad material belt to roll-cut and form individual nose pads from the nose pad material belt, and the conveyor belt module 75 outputs the nose pads. The upper nose pad manipulator 21 picks up the nose pads output by the conveyor belt module 75 and places them on the first cup-shaped cover body and the second cup-shaped cover body after stacking and pressing.

[0041] In this embodiment, the first cup-shaped cover body forming machine 6 includes a support frame 27 installed on the machine table 1 and erected above the annular circulating conveying mechanism 2, a plurality of first material roll racks 28 installed on the machine table 1, and a hemming and welding mechanism 29, a folding mechanism 30, an outer shape welding mechanism 31, an unfolding and flattening mechanism 32, and a turning guide roller 33 arranged in a straight line on the support frame 27. The support frame 27 is equipped with a deviation rectifying mechanism 34, a buffer mechanism 35, a pressing mechanism 36, a first cutting mechanism 37, and a punching and expanding mechanism 38. The deviation rectifying mechanism 34, the buffer mechanism 35, the pressing mechanism 36, the first cutting mechanism 37, and the punching and expanding mechanism 38 are sequentially arranged above the circumferential side of the annular circulating conveying mechanism 2 along the conveying direction of the annular circulating conveying mechanism 2. The processing and forming die 3 is elastically connected to the circulating conveying part of the annular circulating conveying mechanism 2. A processing and forming hole 39 is opened in the middle of the processing and forming die 3, and a plurality of positioning pins 40 are arranged on the top surface of the processing and forming die 3. The plurality of positioning pins 40 are arranged around the processing and forming hole 39. The machine table 1 is equipped with a support base 41 and an upper top support mechanism 42. The support base 41 is located below the processing and forming die 3 and is arranged opposite to the pressing mechanism 36. The support base 41 is used to support the processing and forming die 3. The upper top support mechanism 42 is located below the processing and forming die 3 and is arranged opposite to the punching and expanding mechanism 38. The pressing mechanism 36 is used to press the flattened and deviation-rectified first fabric onto the plurality of positioning pins 40 of the processing and forming die 3. The first cutting mechanism 37 is used to cut the first fabric between two adjacent processing and forming dies 3. The punching and expanding mechanism 38 is used to expand the outer shape welding part of the first fabric carried by the processing and forming die 3 in the processing and forming hole 39 to form the first cup-shaped cover body. Specifically, the arrangement directions of the hemming and welding mechanism 29, the folding mechanism 30, the outer shape welding mechanism 31, the unfolding and flattening mechanism 32, and the turning guide roller 33 are opposite to the arrangement directions of the deviation rectifying mechanism 34, the buffer mechanism 35, the pressing mechanism 36, the first cutting mechanism 37, and the punching and expanding mechanism 38 and form an upper and lower layer layout. This structural setting makes the structure of the first cup-shaped cover body forming machine 6 compact. The moving path of the first fabric is roughly U-shaped, which can not only change the direction of the first fabric but also change the orientation of the outer shape welding part of the first fabric, so that the outer shape welding part on the first fabric changes from opening downward to opening upward, which is beneficial to the subsequent processing of the first cup-shaped cover body formed by the first cup-shaped cover body forming machine 6.

[0042] In practical applications, multiple first fabric rolls (moon fabric rolls) are respectively installed on multiple first roll racks 28. The first fabric layers of the multiple first fabric rolls are stacked together. The edge welding mechanism 29 welds the multiple layers of the first fabric together. The folding mechanism 30 folds the multiple layers of the first fabric that are welded together. The outer shape welding mechanism 31 performs outer shape welding on the folded multiple layers of the first fabric. The unfolding and flattening mechanism 32 roughly unfolds and flattens the multiple layers of the first fabric after outer shape welding. The multiple layers of the first fabric after unfolding and flattening pass around the turning guide roller 33, so that the multiple layers of the first fabric turn and then pass through the deviation correction mechanism 34 for deviation correction. The buffer mechanism 35 buffers the multiple layers of the first fabric. The pressing mechanism 36 cooperates with the support base 41 to press the multiple layers of the first fabric onto the processing and forming die 3. Multiple positioning pins 40 on the processing and forming die 3 pierce the multiple layers of the first fabric. At this time, the outer shape welding part on the first fabric is located at the processing and forming hole 39 of the processing and forming die 3. As the processing and forming die 3 moves, the processing and forming die 3 pulls the multiple layers of the first fabric to move. The first cutting mechanism 37 cuts the fabric between two adjacent processing and forming dies 3, so that the processing and forming die 3 conveys a single first cup-shaped cover body. The stamping and expanding mechanism 38 cooperates with the upper top support mechanism 42 to perform stamping and expanding on the first cup-shaped cover body carried by the processing and forming die 3, so as to finally form the first cup-shaped cover body.

[0043] Specifically, the unfolding and flattening mechanism 32 includes an unfolding and flattening guide plate that is roughly conical. The multiple layers of the first fabric after folding and outer shape welding gradually unfold and flatten along the unfolding and flattening guide plate.

[0044] Specifically, a horizontal rolling and conveying mechanism is arranged between the edge welding mechanism 29 and the folding mechanism 30, and the horizontal rolling and conveying mechanism conveys the multiple layers of the first fabric after welding; a vertical rolling and conveying mechanism is arranged between the outer shape welding mechanism 31 and the unfolding and flattening mechanism 32, and the vertical rolling and conveying mechanism drives the multiple layers of the first fabric after folding to be conveyed.

[0045] In this embodiment, the downward pressing mechanism 36 includes a pressing plate 43 that is vertically arranged above the processing and forming die 3 and a downward pressing driver 44 that is installed on the support frame 27 and used to drive the pressing plate 43 to move up and down. A plurality of through holes 45 are arranged on the periphery of the pressing plate 43, and the plurality of through holes 45 are respectively arranged in one-to-one correspondence with a plurality of positioning pins 40; the stamping and expanding mechanism 38 includes a stamping and expanding head 46 that is vertically arranged above the processing and forming die 3 and corresponds to the processing and forming hole 39 and a expanding driver 47 that is installed on the support frame 27 and used to drive the stamping and expanding head 46 to move up and down. The upward supporting mechanism 42 includes an upward supporting female die 48 that is vertically arranged below the processing and forming die 3 and an upward supporting driver 49 that is installed on the machine table 1 and used to drive the upward supporting female die 48 to move up and down. The stamping and expanding head 46 can pass through the processing and forming hole 39 and insert into the cavity of the upward supporting female die 48; specifically, the downward pressing driver 44, the expanding driver 47, and the upward supporting driver 49 can all adopt air cylinders.

[0046] In practical applications, the downward pressing driver 44 drives the pressing plate 43 to move downward, so that the pressing plate 43 presses the flattened multi-layer first fabric downward on the processing and forming die 3. The plurality of positioning pins 40 on the processing and forming die 3 pierce the multi-layer first fabric and then insert into the corresponding through holes 45 to realize the positioning connection between the processing and forming die 3 and the multi-layer first fabric. Then, the downward pressing driver 44 drives the pressing plate 43 to move upward and reset. The processing and forming die 3 drives the multi-layer first fabric to move forward. The first cutting mechanism 37 cuts the multi-layer first fabric. When the processing and forming die 3 moves a single first cup-shaped cover body to the stamping and expanding mechanism 38, the expanding driver 47 drives the stamping and expanding head 46 to move downward, and the upward supporting driver 49 drives the upward supporting female die 48 to move upward. Under the cooperation of the stamping and expanding head 46 and the upward supporting female die 48, the stamping and expanding head 46 expands and forms the outer shape welding part of the first cup-shaped cover body.

[0047] In this embodiment, the second cup-shaped cover body forming machine 4 includes a second material roll holder 50, a buffer material mechanism 51, a first pulling mechanism 52, a front pressing mechanism 53, a second cup-shaped cover body thermoforming mechanism 54, a rear pressing mechanism 55, a second pulling mechanism 56, a second cutting mechanism 57, and a discharging station 58 that are arranged in sequence. The flipping and loading device 11 is used to flip and load the second cup-shaped cover body at the discharging station 58 onto the first cup-shaped cover body carried by the processing and forming die 3.

[0048] In practical applications, the second fabric roll (needled cotton fabric roll) is installed on the second fabric roll stand 50. The second fabric of the second fabric roll sequentially passes through the buffer fabric mechanism 51, the first pulling mechanism 52, the front pressing mechanism 53, the second cup-shaped cover body thermoforming mechanism 54, the rear pressing mechanism 55, the second pulling mechanism 56, and the second cutting mechanism 57. The buffer fabric mechanism 51 buffers the second fabric for a certain length. When the second cup-shaped cover body thermoforming mechanism 54 thermo-presses and forms the second cup-shaped cover body on the second fabric, the front pressing mechanism 53 and the rear pressing mechanism 55 are in a state of pressing the second fabric to ensure the quality of the second cup-shaped cover body thermo-pressed and formed on the second fabric. After the second cup-shaped cover body is formed on the second fabric, the front pressing mechanism 53 and the rear pressing mechanism 55 release the second fabric, and the first pulling mechanism 52 and the second pulling mechanism 56 synchronously pull the second fabric to realize the conveyance of the second fabric. The second fabric formed with the second cup-shaped cover body will move to the discharging station 58, and the second cutting mechanism 57 cuts the second fabric to form a single second cup-shaped cover body on the discharging station 58. The flipping and loading device 11 flips the second cup-shaped cover body on the discharging station 58 to the processing and forming die 3 where the stacking and pressing device 7 is located. The second cup-shaped cover body is flipped from the opening facing down to the opening facing up, so that the second cup-shaped cover body is stacked on the first cup-shaped cover body carried by the processing and forming die 3. Then, the stacking and pressing device 7 presses the second cup-shaped cover body and the first cup-shaped cover body together.

[0049] In this embodiment, clamping grooves 59 are provided on both sides of the processing and forming die 3. The demolding mechanism 10 includes two demolding components 60 oppositely installed on the machine table 1. The demolding component 60 includes a translation driver 61 installed on the machine table 1, a lifting driver 62 installed on the translation end of the translation driver 61, a finger cylinder 63 installed on the lifting end of the lifting driver 62, and two demolding clamping blocks 64 installed on the two output ends of the finger cylinder 63. The two demolding clamping blocks 64 can extend into the clamping groove 59 to clamp the edge of the cup-shaped mask body. Specifically, both the translation driver 61 and the lifting driver 62 can adopt air cylinders.

[0050] In practical applications, when the processing and forming die 3 conveys the cup-shaped mask body to the demolding mechanism 10, the translation driver 61 drives the lifting driver 62, along with the finger cylinder 63 and the two demolding clamping blocks 64, to move closer to the processing and forming die 3 until the two demolding clamping blocks 64 extend into the clamping groove 59 and the edge of the cup-shaped mask body is located between the two demolding clamping blocks 64. At this time, the finger cylinder 63 drives the two demolding clamping blocks 64 to approach each other until the two demolding clamping blocks 64 clamp the edge of the cup-shaped mask body. Then, the lifting driver 62 drives the finger cylinder 63, along with the two demolding clamping blocks 64 and the cup-shaped mask body, to move upward. Under the coordinated cooperation of the demolding assembly 60, the cup-shaped mask body is taken out from the processing and forming die 3 to achieve the demolding of the cup-shaped mask body. Finally, the flipping device 15 can flip the cup-shaped mask body on the demolding mechanism 10 to the receiving station 12 of the feeding mechanism 5, and the opening of the cup-shaped mask body on the receiving station 12 faces downward.

[0051] In this embodiment, the outer shape cutting and forming device 16 includes a gantry 65 installed on the machine table 1 and straddling the feeding mechanism 5, an outer shape cutting bottom die 66 installed on the machine table 1 and located in the middle of the feeding mechanism 5, an outer shape cutting knife 67 arranged above the outer shape cutting bottom die 66 in a lifting manner, an outer shape cutting lifter 68 installed on the gantry 65 and used to drive the outer shape cutting knife 67 to lift and lower, and two pressing mechanisms 69 respectively installed on the front and rear sides of the gantry 65. The two pressing mechanisms 69 are used to press the edge of the cup-shaped mask body against the outer shape cutting bottom die 66. Specifically, the outer shape cutting lifter 68 can adopt a cylinder.

[0052] In practical applications, the feeding mechanism 5 conveys the cup-shaped mask body to the outer shape cutting and forming device 16. The two pressing mechanisms 69 press the two side edges of the cup-shaped mask body. Then, the outer shape cutting lifter 68 drives the outer shape cutting knife 67 to move downward until the outer shape cutting knife 67 cooperates with the outer shape cutting bottom die 66 to perform outer shape cutting on the pressed cup-shaped mask body, so as to cut and form a cup-shaped mask main body on the cup-shaped mask body. Before the outer shape cutting, the edge of the cup-shaped mask body is pressed by the pressing mechanism 69, which improves the quality of the outer shape cutting.

[0053] In this embodiment, the feeding mechanism 5 includes two support platforms 70 installed on the machine table 1 and located on the front and rear sides of the outer shape cutting bottom die 66 respectively, two groups of clamping and moving modules 71 movably arranged on the machine table 1, and a reciprocating moving driving module 72 installed on the machine table 1 and used to drive the two groups of clamping and moving modules 71 to move synchronously back and forth. The two groups of clamping and moving modules 71 are arranged oppositely, the support platform 70 is located between the two groups of clamping and moving modules 71, and the two support platforms 70 are respectively located at the material receiving station 12 and the material discharging station 14. The clamping and moving module 71 includes a moving seat 73 slidably connected to the machine table 1 and at least three clamping components 74 installed on the moving seat 73. The reciprocating moving driving module 72 is drivingly connected to the moving seat 73 and is used to drive the moving seat 73 to move back and forth. Preferably, the number of the clamping components 74 is three. The reciprocating moving driving module 72 adopts a conveyor belt module.

[0054] In practical applications, the flipping device 15 flips the cup-shaped mask body onto the support platform 70 located at the material receiving station 12. The reciprocating moving driving module 72 drives the two groups of clamping and moving modules 71 to perform progressive feeding on the cup-shaped mask body, so that the cup-shaped mask body moves at the material receiving station 12, the outer shape cutting and forming station 13, and the material discharging station 14. The outer shape cutting and forming device 16 performs outer shape cutting on the cup-shaped mask body to form a cup-shaped mask main body. The material discharging device 17 discharges the cup-shaped mask main body to a preset position, and the last clamping component 74 in the clamping and moving module 71 clamps the waste material at the waste material collection position.

[0055] Specifically, a material taking through hole is formed in the middle of the support platform 70 located at the material discharging station 14, and a suction profiling head is arranged at the execution end of the material discharging device 17. The suction profiling head can extend into the material taking through hole. When the cup-shaped mask body with the cup-shaped mask main body after outer shape cutting is located on the support platform 70 at the material discharging station 14, at this time, the clamping components 74 of the two groups of clamping and moving modules 71 respectively clamp both sides of the cup-shaped mask body, and the cup-shaped mask main body on the cup-shaped mask body is correspondingly arranged with the material taking through hole. Then, the material discharging device 17 drives the suction profiling head to move downwards, so that the suction profiling head can tightly suck the cup-shaped mask main body and extend into the material taking through hole until the cup-shaped mask main body is separated from the waste material. Then, the material discharging device 17 drives the suction profiling head to rise together with the cup-shaped mask main body and pick it up to the preset material discharging position, and the clamping components 74 of the two groups of clamping and moving modules 71 clamp the waste material at the waste material collection position when feeding forward.
