Description

Technical Field

[0001] The present invention relates to the technical field of cup-shaped mask machines, and in particular to a mask forming machine for cup-shaped masks. Background Art

[0002] The mask is an important part of the cup-shaped mask. During the production process of the cup-shaped mask, it is necessary to first produce and form the mask, and then perform subsequent processing on the mask to form the cup-shaped mask. Since the produced mask is in a folded planar shape, in the prior art, it is necessary to manually open the planar mask, and then manually or by a manipulator cover the opened mask on the cup-shaped mask body. Since the planar mask needs to be manually opened before it can be covered on the cup-shaped mask body for subsequent processing, the processing of the mask and the combined processing of the mask and the cup-shaped mask body need to be completed in two stages, and manual participation is also required, resulting in the inability to achieve automatic connection between the mask and the cup-shaped mask body, which is not conducive to realizing the fully automatic production of cup-shaped masks. Therefore, the defect is very obvious, and a solution is urgently needed. Summary of the Invention

Detailed implementation manners

[0029] For the convenience of those skilled in the art to understand, the present invention 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 invention.

[0030] As Figures 1 to 11 shown, a mask forming machine for a cup-shaped mask provided by the present invention includes a machine table 1, a cloth feeding mechanism 12 installed on the machine table 1, a cloth edge welding mechanism 3, a cloth folding mechanism 4, a rolling and conveying mechanism 41, a contour roll cutting and forming mechanism 42, a material guiding and traction mechanism 7, a mask folding and forming device 8, and a cutting mechanism 9 and a clamping mechanism 11 respectively installed above the material guiding and traction mechanism 7. The cutting mechanism 9 and the clamping mechanism 11 are respectively located at both ends of the mask folding and forming device 8, and the cutting mechanism 9 and the clamping mechanism 11 are distributed along the traction direction of the material guiding and traction mechanism 7. Specifically, the cloth folding mechanism 4 can adopt a folding device in the prior art, which will not be elaborated here.

[0031] In practical applications, multiple layers of horizontally arranged cloth pass through the cloth edge welding mechanism 3. The cloth edge welding mechanism 3 welds the two side edges of the cloth. The cloth after side edge welding is horizontally rolled and conveyed by the cloth feeding mechanism 12, so that the cloth moves along the processing direction. The cloth folding mechanism 4 folds the cloth after side edge welding. The rolling and conveying mechanism 41 vertically rolls and conveys the folded cloth, which can not only convey the cloth, but also press the folded cloth. Then, the contour roll cutting and forming mechanism 42 performs contour cutting and forming on the top edge of the folded cloth, so that the top edge of the folded cloth is in a moon shape or an arc shape. The material guiding and traction mechanism 7 guides and traction the cloth after contour cutting and forming until the material guiding and traction mechanism 7 tractions the cloth to the clamping mechanism 11. The moving distance of the material guiding and traction mechanism 7 for each traction of the cloth is the length of a single mask 01. The clamping mechanism 11 clamps one end of the cloth, and then the cutting mechanism 9 cuts the cloth at a specific position to form a single mask 01. Finally, the mask folding and forming device 8 turns up the bottom edge of the mask 01 upward, so that the transfer manipulator can pick up the turned-up edge of the turned-up mask 01 and can open it and cover it on the cup-shaped mask body, which is beneficial to the automated production of the cup-shaped mask. The present invention can not only automatically produce the mask 01, but also perform folding and forming on the mask 01, so as to cooperate with the transfer manipulator to perform automated operations on the mask 01, and is particularly suitable for application in the automated production line of the cup-shaped mask.

[0032] In this embodiment, the mask folding and forming device 8 includes a folding and forming seat 81 installed on the machine 1, a material-supporting auxiliary folding assembly 82 arranged on the folding and forming seat 81, two side pull members 83 located on both sides of the material-supporting auxiliary folding assembly 82, a side pull driving mechanism 84 arranged on the folding and forming seat 81 and used to drive the two side pull members 83 to move closer to or away from each other, two folding and forming members 85 located on both sides of the material-supporting auxiliary folding assembly 82, and a folding and lifting driving mechanism 86 used to drive the two folding and forming members 85 to rise and fall. The two side pull members 83 are respectively arranged in a one-to-one correspondence with the two folding and forming members 85, the material-supporting auxiliary folding assembly 82 is provided with a material-supporting gap 87, the side pull member 83 is provided with a side pull protrusion 88, and the folding and forming member 85 is provided with an avoidance groove 89, which is used to provide an avoidance space for the side pull protrusion 88, and the feeding end of the material-supporting gap 87 is arranged corresponding to the material guiding and traction mechanism 7.

[0033] In actual application, when the material guiding and pulling mechanism 7 pulls the fabric after the shape cutting and forming into the material supporting gap 87, the material supporting auxiliary folding component 82 supports the middle part of the two sides of the mask 01, and the pull edge protrusions 88 of the two pull edge parts 83 are both located in the mask 01, and then the pull edge driving mechanism 84 drives the two pull edge parts 83 to move away from each other, so that the pull edge protrusions 88 of the two pull edge parts 83 pull the bottom edge of the mask 01 outward to realize the opening of the bottom opening of the mask 01, and the two bottom edges of the mask 01 correspond to the two folding forming parts 85 respectively, and then the folding lifting and lifting driving mechanism 86 drives the two folding forming parts 85 to move upward, so that the two folding forming parts 85 resist the two bottom edges of the mask 01 and move upward, under the auxiliary action of the material supporting auxiliary folding component 82, the two folding forming parts 85 fold the two bottom edges of the mask 01 upward along the pressure edge of the material supporting auxiliary folding component 82 to realize the upward folding of the edge of the mask. Since the avoidance groove 89 provides an avoidance space for the edge-pulling protrusion 88, the edge-pulling member 83 and the folding molding member 85 will not collide or interfere during operation, and the structure is compact. The structural design of the mask folding molding device 8 is reasonable and compact, and the bottom edge of the mask 01 is automatically folded, with high folding efficiency and good quality, reducing the cost and labor intensity of labor, and the folded edge of the folded mask 01 can be picked up by the transfer robot and the mask 01 can be opened and covered on the cup-shaped mask body, which is particularly suitable for automated production lines and is conducive to the automated production of cup-shaped masks.

[0034] In this embodiment, the folding and forming seat 81 is slidably connected to the folding movable plate 811, and the folding and forming seat 81 is equipped with a folding movable driving mechanism 812. The moving end of the folding movable driving mechanism 812 is connected to the folding movable plate 811, and the material supporting auxiliary folding component 82 and the edge pulling driving mechanism 84 are both installed on the folding movable plate 811; specifically, the folding movable driving mechanism 812 can adopt a cylinder or a screw module.

[0035] In practical applications, after the mask 01 with the outer shape cut and formed is moved into place, the folding and moving drive mechanism 812 drives the folding and moving plate 811 to drive the material-supporting and auxiliary folding assembly 82, the edge-pulling drive mechanism 84, and the two edge-pulling members 83 to move to the position corresponding to the mask 01 with the outer shape cut and formed, so that the mask 01 with the outer shape cut and formed is located within the material-supporting gap 87, and the edge-pulling bumps 88 of the two edge-pulling members 83 are located within the mask 01 with the outer shape cut and formed. This structural design is conducive to the mask 01 with the outer shape cut and formed entering the material-supporting gap 87.

[0036] Specifically, the folding and moving plate 811 is provided with a lifting space, and the lifting space provides a space for the two folding and forming members 85 to lift.

[0037] Specifically, the edge-pulling drive mechanism 84 is composed of two edge-pulling cylinders. The two edge-pulling cylinders are respectively installed on the folding and moving plate 811 and are located on both sides of the lifting space. The two edge-pulling cylinders are respectively drivingly connected to the two edge-pulling members 83, and the two edge-pulling cylinders are arranged oppositely and work synchronously.

[0038] Specifically, the two folding and forming members 85 are connected via a connecting plate 813. The connecting plate 813 is located below the material-supporting and auxiliary folding assembly 82, and the connecting plate 813 is connected to the lifting end of the folding and lifting drive mechanism 86.

[0039] Specifically, the material-supporting and auxiliary folding assembly 82 includes two material-supporting and folding pressing plates 821 arranged at intervals and in parallel. The two material-supporting and folding pressing plates 821 enclose a material-supporting gap 87. The mask 01 with the outer shape cut and formed moves into the material-supporting gap 87, and the two material-supporting and folding pressing plates 821 support the two outer side walls of the mask 01; when the folding and forming member 85 folds the bottom edge of the mask 01, the material-supporting and folding pressing plates 821 play a role in pressing the edge, so that the bottom edge of the mask 01 can be folded upward around the material-supporting and folding pressing plates 821.

[0040] Specifically, the material-supporting and auxiliary folding assembly 82 further includes a mounting seat 822 installed on the folding and moving plate 811. One end of each of the two material-supporting and folding pressing plates 821 is installed on the mounting seat 822. This structural design facilitates the fixed installation of the two material-supporting and folding pressing plates 821.

[0041] Specifically, the mounting seat 822 is provided with a locking and adjusting groove 823 for locking and adjusting the material-supporting and folding pressing plates 821. According to masks 01 with different thicknesses, the position of the material-supporting and folding pressing plates 821 on the mounting seat 822 is adjusted through the locking and adjusting groove 823 to adjust the distance between the two material-supporting and folding pressing plates 821, so as to adjust the size of the material-supporting gap 87. After the adjustment is completed, the material-supporting and folding pressing plates 821 are locked to the mounting seat 822 through bolts.

[0042] In this embodiment, the mask forming machine for cup-shaped masks further includes a marking mechanism 2 disposed on the side of the outer shape roll cutting and forming mechanism 42 away from the rolling and conveying mechanism 41, and a marking detection mechanism 21 disposed between the marking mechanism 2 and the material guiding and traction mechanism 7. The marking detection mechanism 21 is electrically connected to the material guiding and traction mechanism 7. The outer shape roll cutting and forming mechanism 42 can adopt a melting and cutting method to achieve the outer shape cutting and welding of the fabric.

[0043] In practical applications, after the outer shape roll cutting and forming mechanism 42 performs outer shape roll cutting and forming on the folded fabric, the marking mechanism 2 marks a specific position of the fabric. This mark is used for the marking detection mechanism 21 to detect. During the process of the material guiding and traction mechanism 7 pulling the fabric to move, when the fabric moves a length equal to that of a mask 01, the marking detection mechanism 21 just detects this mark, proving that the moving length of the fabric reaches the preset length. Then the marking detection mechanism 21 feeds back a signal to the material guiding and traction mechanism 7, causing the material guiding and traction mechanism 7 to stop pulling the fabric, and the clamping mechanism 11 clamps the free end of the fabric, and the shearing mechanism 9 shears the fabric to produce a single mask 01. Marking on the fabric and controlling the moving length of the fabric by automatically detecting the mark improves the accuracy and precision of the fabric movement, and ensures that the length of each mask 01 is consistent, thus ensuring the quality of each mask 01.

[0044] Specifically, the shearing mechanism 9 includes a shearing frame 91 mounted on the machine table 1, a shearing lifting cylinder 92 mounted on the shearing frame 91, a shearing driving cylinder 93 mounted on the piston rod of the shearing lifting cylinder 92, and a scissor assembly 94 drivingly connected to the piston rod of the shearing driving cylinder 93. The side wall of the cylinder body of the shearing driving cylinder 93 is slidably connected to the shearing frame 91; the shearing lifting cylinder 92 is used to drive the shearing driving cylinder 93 and the scissor assembly 94 to lift and lower, and the shearing driving cylinder 93 is used to drive the scissor assembly 94 to shear the fabric.

[0045] In this embodiment, the mask forming machine for cup-shaped masks further includes a tension storage mechanism 6 disposed on the side of the outer shape roll cutting and forming mechanism 42 away from the rolling and conveying mechanism 41. The tension storage mechanism 6 is located between the marking mechanism 2 and the marking detection mechanism 21. To avoid frequent shutdowns, ensure that the fabric can be normally and continuously transported and processed, and improve the production efficiency of the mask 01, when the mask folding and forming device 8 performs folding and forming on the mask 01, the tension storage mechanism 6 not only provides a constant tension to the fabric, but also can store the fabric. When the material guiding and traction mechanism 7 stops pulling the fabric, the tension storage mechanism 6 stores a certain length of the fabric. When the material guiding and traction mechanism 7 pulls the fabric, the tension storage mechanism 6 can release the stored fabric for the material guiding and traction mechanism 7 to pull.

[0046] In this embodiment, the tension storage mechanism 6 includes a storage rack 61 installed on the machine table 1, two guide rollers 62 rotatably connected to the storage rack 61, a sliding seat 63 slidably connected to the storage rack 61, a tension roller 64 rotatably connected to the sliding seat 63, a guide wheel 65 rotatably connected to the storage rack 61, a connecting rope 66 wound around the guide wheel 65, and a counterweight 67 connected to one end of the connecting rope 66. The other end of the connecting rope 66 is connected to the sliding seat 63. The tension roller 64 is located between the two guide rollers 62. The sliding direction of the sliding seat 63 is arranged crosswise to the feeding direction of the feeding mechanism 12. The fabric is sequentially wound around one guide roller 62, the tension roller 64, and the other guide roller 62.

[0047] In practical applications, the feeding mechanism 12, the rolling and conveying mechanism 41, and the profile roller cutting and forming mechanism 42 continuously convey the fabric. During the conveying process of the fabric, the two guide rollers 62 roll against the fabric to limit the fabric. When the mask folding and forming device 8 folds and forms the mask 01 and the guide and traction mechanism 7 stops pulling the fabric, the fabric between the profile roller cutting and forming mechanism 42 and the guide and traction mechanism 7 gradually increases. To ensure that the fabric maintains a constant tension, the counterweight 67 moves downward under its own weight and pulls the sliding seat 63 and the tension roller 64 to move horizontally via the connecting rope 66. The moving tension roller 64 pulls the fabric to move a certain distance along the direction perpendicular to the fabric feeding to store a certain length of the fabric. When the mask folding and forming device 8 finishes folding the mask 01 and the folded mask 01 is taken away, the guide and traction mechanism 7 pulls the fabric to move to realize the feeding of the fabric. During this process, the fabric will exert a certain force on the tension roller 64. When this force is greater than the gravity of the counterweight 67, this force will pull the tension roller 64 together with the sliding seat 63 to move back to release the stored fabric. The sliding seat 63 that moves back together with the connecting rope 66 pulls the counterweight 67 to move upward and reset. This tension storage mechanism 6 can not only apply a constant tension to the fabric but also store the fabric, solving the problem of frequent shutdowns due to inconsistent speeds of the front and back processing stations and ensuring that the machine can continuously operate.

[0048] In this embodiment, a clamping mechanism 5 is provided on one side of the tension storage mechanism 6 close to the guide and traction mechanism 7. The clamping mechanism 5 includes a clamping cylinder 51 installed on the machine table 1 and two clamping blocks 52 installed on the two output ends of the clamping cylinder 51. The clamping cylinder 51 is used to drive the two clamping blocks 52 to approach or separate from each other.

[0049] In practical applications, while the clamping mechanism 11 clamps one end of the fabric, the clamping mechanism 5 clamps the fabric. At this time, the material guiding and traction mechanism 7 can be reset to facilitate the next traction operation. Since the clamping mechanism 11 and the clamping mechanism 5 clamp the fabric respectively, it is beneficial for the shearing mechanism 9 to shear the fabric stably and efficiently. Specifically, the clamping cylinder 51 drives the two clamping blocks 52 to approach each other and clamp the fabric. When it is necessary to convey the fabric, the clamping cylinder 51 drives the two clamping blocks 52 to move away from each other to release the fabric, and the two clamping blocks 52 play a role in limiting the conveyed fabric, ensuring the stability of the fabric movement. When the two clamping blocks 52 are opened, it is also convenient for the fabric to pass through the clamping mechanism 5, especially for the machine adjustment and the preparation work before the machine operates.

[0050] In this embodiment, the material guiding and traction mechanism 7 includes a material guiding component 71 installed on the machine table 1, a traction driving mechanism 72 installed on the machine table 1, and a material clamping mechanism 73 connected to the traction end of the traction driving mechanism 72. The material guiding gap of the material guiding component 71 corresponds to and communicates with the material supporting gap 87. The traction driving mechanism 72 is used to drive the material clamping mechanism 73 to approach or move away from the clamping mechanism 11.

[0051] In practical applications, the material guiding component 71 guides the fabric after the outer shape is cut and formed. When it is necessary to traction the fabric, the material clamping mechanism 73 clamps the fabric, and the traction driving mechanism 72 drives the material clamping mechanism 73 to drive the fabric to move in the direction close to the clamping mechanism 11. The fabric moves along the material guiding gap of the material guiding component 71, improving the stability of the fabric movement. Until the clamping mechanism 11 and the clamping mechanism 5 clamp the fabric respectively, the material clamping mechanism 73 releases the fabric, and the traction driving mechanism 72 drives the material clamping mechanism 73 to reset and move. With this structural design, the stability of the traction fabric movement is good.

[0052] In this embodiment, the marking mechanism 2 includes a marking seat 22 installed on the machine table 1, a marking die 23 installed on the marking seat 22, a marking cylinder 24 installed on one side of the marking die 23 or / and the marking seat 22, a marking rod 25 installed on the piston rod of the marking cylinder 24, and a waste collector 26 installed on the other side of the marking die 23 or / and the marking seat 22. The marking die 23 is provided with a material passing groove 27 and a marking hole 28 that communicates with the material passing groove 27 and penetrates through the marking die 23. The marking rod 25 is slidably connected to the marking hole 28, and the waste collector 26 communicates with one end of the marking hole 28 far from the marking cylinder 24. Specifically, the marking detection mechanism 21 can adopt a pair of opposed photoelectric sensors.

[0053] In practical applications, the moving fabric passes through the material trough 27. During the movement of the fabric, the marking cylinder 24 drives the marking rod 25 to slide along the marking hole 28 and pass through the material trough 27, so that the marking rod 25 punches holes at specific positions of the fabric to mark the fabric. The waste materials will be collected or discharged through the waste collector 26. The marking detection mechanism 21 detects the hole positions to facilitate the control of the length of the traction fabric movement.

[0054] In this embodiment, the fabric edge welding mechanism 3 includes a welding frame 31 installed on the machine table 1, a rotating roller 32 rotatably connected to the welding frame 31, two welding roller dies 33 spacedly installed on the rotating roller 32, a welding rotation driving mechanism 34 installed on the welding frame 31 and used to drive the rotating roller 32 to rotate, and an ultrasonic welding machine 35 arranged below the two welding roller dies 33; the two welding roller dies 33 are respectively locked on the rotating roller 32 via bolts, so that the distance between the two welding roller dies 33 is adjustable to meet the welding of the sides of fabrics with different widths.

[0055] In practical applications, the horizontally arranged fabric passes through the welding roller dies 33 and the welding head of the ultrasonic welding machine 35.
