Description

Technical Field

[0001] This utility model relates to the field of mask machine technology, and in particular to a mask body forming equipment. Background Technology

[0002] The applicant filed a Chinese patent application on September 3, 2024, with application number 202411229304.5, disclosing a cup-shaped mask body production equipment. The equipment includes a machine base, a circular conveying mechanism mounted on the machine base, multiple processing and forming molds disposed in the circular conveying section of the circular conveying mechanism, a second cup-shaped mask forming machine located outside one end of the circular conveying mechanism and forming a second cup-shaped mask body, a feeding mechanism located outside the other end of the circular conveying mechanism, and a first cup-shaped mask forming machine, a stacking and pressing device, an ultrasonic welding device, a sponge strip attaching device, and a demolding mechanism arranged sequentially around the periphery of the circular conveying mechanism along its conveying direction. The first cup-shaped mask forming machine supplies the first cup-shaped mask body to the processing and forming molds. The stacking and pressing device is located at one end of the circular conveying mechanism near the second cup-shaped mask forming machine. A flipping feeding device is provided between the pressing device and the second cup-shaped mask forming machine. The flipping feeding device is used to flip the second cup-shaped mask formed by the second cup-shaped mask forming machine onto the first cup-shaped mask carried by the processing forming mold. The demolding mechanism is located at one end of the annular circulating conveyor mechanism near the feeding mechanism. The demolding mechanism is used to remove the cup-shaped mask body carried by the processing forming mold. The feeding direction of the feeding mechanism is arranged with a receiving station, a shape cutting and forming station and a unloading station in sequence. A flipping device is provided between the feeding mechanism and the demolding mechanism. The flipping device is used to flip the cup-shaped mask body picked up by the demolding mechanism onto the receiving station of the feeding mechanism. The machine is equipped with a shape cutting and forming device located at the shape cutting and forming station and an unloading device movably set above the unloading station. The shape cutting and forming device is used to cut and form the cup-shaped mask body from the cup-shaped mask body. Because the circular conveyor mechanism used in this patent document circulates multiple forming molds on a plane, the equipment occupies a large area on the plane, making it unsuitable for use in confined spaces (where space is limited), especially when users need to use multiple devices simultaneously. Therefore, the drawbacks are quite obvious, and a solution is urgently needed. Utility Model Content

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] like Figures 1 to 8 As shown, the present invention provides a mask body forming equipment, which includes a machine base 1, an outer cover forming line 2 set on one side of the machine base 1, an inner cover fabric rack 3, an inner cover welding mechanism 4, a first flat roller pressing conveyor 5, a folding mechanism 6, a welding and shaping mechanism 7, a vertical roller pressing conveyor 8, an unfolding mechanism 9, a second flat roller pressing conveyor 10, and a linear circulating conveyor 11, an inner and outer cover combination forming machine 12 set outside the output side of the linear circulating conveyor 11, multiple conveying carriers 13 set on the circulating conveying surface of the linear circulating conveyor 11, a pressing and stapling mechanism 14 installed on the machine base 1 and sequentially erected above the linear circulating conveyor 11, an inner cover cutting mechanism 15, an inner cover stamping and forming mechanism 16, an inner and outer cover edge pressing mechanism 17, an ultrasonic welding forming device 18, and a clamping device. The system includes a demolding mechanism 19, a transfer robot 20 mounted on the machine base 1 and movably positioned at the input end of the clamping demolding mechanism 19 and the inner and outer cover combination molding machine 12, an inner and outer cover stacking station 21 positioned between the inner cover stamping molding mechanism 16 and the inner and outer cover pressing mechanism 17, and a stacking robot 22 movably positioned above the outer cover forming line 2 and the inner and outer cover stacking station 21. The outer cover forming line 2 processes and forms the outer cover body. A linear circulating conveyor 11 is used to transport multiple conveyor carriers 13 to rotate cyclically on a vertical plane. A through hole 23 is opened in the middle of the conveyor carrier 13. Multiple positioning pins 24 are arranged around the periphery of the through hole 23 on the top edge of the conveyor carrier 13. A pin pressing mechanism 14 is used to press the edge of the unfolded fabric onto the multiple positioning pins 24 of the conveyor carrier 13. The outer cover forming line 2 and the linear circulating conveyor 11 are arranged side by side.

[0026] In practical applications, the outer cover forming line 2 processes and forms the outer cover body. Simultaneously, the inner cover welding mechanism 4 welds the multi-layered inner cover fabric supplied by the inner cover fabric rack 3. The first flat roller conveying mechanism 5 roller conveys the welded inner cover fabric. The folding mechanism 6 folds the welded inner cover fabric. The molten-cutting mechanism 7 performs molten-cutting on the folded inner cover fabric. The vertical roller conveying mechanism 8 roller conveys the molten-cut inner cover fabric. The unfolding mechanism 9 unfolds (flattens) the molten-cut inner cover fabric. The second flat roller conveying mechanism... The conveying mechanism 10 rolls and conveys the unfolded inner cover fabric. The unfolded inner cover fabric moves above the conveyor carrier 13 of the linear circulating conveyor device 11. The pressing mechanism 14 presses the edges of the unfolded inner cover fabric onto multiple positioning pins 24 on the conveyor carrier 13. The multiple positioning pins 24 position the unfolded inner cover fabric. The conveyor carrier 13 conveys the unfolded inner cover fabric. The inner cover slitting mechanism 15 slits the unfolded inner cover fabric to form individual inner cover body fabric pieces. The conveyor carrier 13 conveys the inner cover body fabric pieces to... The inner cover stamping and forming mechanism 16 stamps and forms the inner cover body fabric to form the inner cover body. The conveyor 13 transports the inner cover body to the inner and outer cover stacking station 21. The stacking robot 22 transfers the outer cover body processed by the outer cover forming line 2 and stacks it on the inner cover body carried by the conveyor 13 to form an inner and outer cover assembly. The conveyor 13 transports the inner and outer cover assembly to the inner and outer cover pressing mechanism 17, which presses the edges of the inner and outer cover assembly against the fixed position of the conveyor 13. On the positioning pin 24, the ultrasonic welding forming device 18 performs ultrasonic welding on the inner and outer cover assembly. Then, the conveyor 13 transports the ultrasonically welded inner and outer cover assembly to the clamping and demolding mechanism 19. The clamping and demolding mechanism 19 pulls the inner and outer cover assembly upward away from the positioning pin 24 of the conveyor 13 to achieve demolding of the inner and outer cover assembly. Then, the transfer robot 20 transfers the inner and outer cover assembly clamped by the clamping and demolding mechanism 19 to the inner and outer cover assembly forming machine 12. The inner and outer cover assembly forming machine 12 processes the inner and outer cover assembly into the mask body. This utility model uses a linear circulating conveyor 11 to circulate multiple conveyor carriers 13 in a vertical plane, reducing the machine's footprint on a plane, and is particularly suitable for situations with limited space on a plane (narrow sites).

[0027] In this embodiment, the inner and outer cover combination molding machine 12 includes a support 25 mounted on the machine base 1, a front receiving carrier 26, a punching and shaping carrier 27 and a rear receiving carrier 28 arranged in a straight line on the support 25, a punching and shaping mechanism 29 mounted above the punching and shaping carrier 27, an output mechanism 30 located below the rear side of the rear receiving carrier 28, a multi-station synchronous clamping and conveying robot 31 arranged horizontally on both sides of the support 25, and an output robot 32 movably arranged above the rear receiving carrier 28.

[0028] In practical applications, the transfer robot 20 transfers the inner and outer mask assembly to the front receiving carrier 26. The punching and forming mechanism 29 cuts and shapes the inner and outer mask assembly carried by the punching and forming carrier 27 to form the mask body. Then, the multi-station synchronous clamping and conveying robot 31 clamps the inner and outer mask assembly carried by the front receiving carrier 26, the punched inner and outer mask assembly carried by the punching and forming carrier 27, and the excess edge material after the output robot 32 takes away the mask body carried by the rear receiving carrier 28 and delivers it. The forward conveying system transports the inner and outer cover assembly carried by the front receiving carrier 26 to the punching and cutting carrier 27. The punched inner and outer cover assembly carried by the punching and cutting carrier 27 is then transported to the rear receiving carrier 28. The excess edge material carried by the rear receiving carrier 28 after the mask body is removed by the output robot 32 is transported to the output mechanism 30. The output mechanism 30 outputs the excess edge material. At this time, the output robot 32 outputs the mask body of the punched inner and outer cover assembly carried by the rear receiving carrier 28 to the designated position.

[0029] In this embodiment, the rear receiving carrier 28 has a pressing hole 62 in the middle. The inner and outer cover combination molding machine 12 also includes a contouring punch 63 disposed in the bracket 25 and raised and lowered below the pressing hole 62, and an upper lifting cylinder 64 mounted on the machine base 1 for driving the contouring punch 63 to rise and fall. The suction head 37 is provided with a contouring die. The contouring die and the contouring punch 63 are arranged vertically and vertically and are adapted to each other.

[0030] In practical applications, the upper cylinder 64 drives the contouring punch 63 to move upward, allowing it to penetrate the lower pressure hole 62 and extend into the blanked inner and outer cover assembly carried by the rear receiving carrier 28, supporting the inner wall of the blanked inner and outer cover assembly. Simultaneously, the contouring die of the output robot 32 moves above the blanked inner and outer cover assembly, with its inner wall contacting the outer wall of the assembly. Then, as the output robot 32 drives the contouring die downward, the upper cylinder 64 drives the contouring punch 63 downward synchronously. This causes the contouring die and the contouring punch 63 to clamp the mask body in the blanked inner and outer cover assembly and move it downward, separating the mask body from the excess material on the rear receiving carrier. The contouring die of the output mechanism 30 then picks up the separated mask body, raises it to the required height, and transports it to the designated position. This structural design facilitates the separation of the mask body from the excess material.

[0031] In this embodiment, the output robot 32 includes a column 33 mounted on the machine base 1, a translation drive mechanism 34 mounted on the column 33, a lifting drive mechanism 35 mounted on the translation end of the translation drive mechanism 34, a rotation drive mechanism 36 mounted on the lifting end of the lifting drive mechanism 35, and a suction head 37 mounted on the rotation end of the rotation drive mechanism 36.

[0032] In practical applications, the translation drive mechanism 34 and the lifting drive mechanism 35 work together to move the suction head 37 above the mask body of the punched inner and outer cover assembly carried by the rear receiving carrier 28. The suction head 37 clamps the mask body, and at this time, the multi-station synchronous clamping and conveying robot 31 clamps the edge of the inner and outer cover assembly. Then, the lifting drive mechanism 35 drives the suction head 37 to rise, causing the suction head 37 to clamp the mask body upward, thereby separating the mask body from the excess edge material. Next, the translation drive mechanism 34 drives the suction head 37, along with the mask body, to move to the designated position, and the suction head 37 releases the mask body, placing it in the designated position. In addition, when it is necessary to adjust the angle of the output mask body, the rotation drive mechanism 36 drives the suction head 37 to rotate. The rotating suction head 37 drives the mask body to rotate, thereby adjusting the angle of the mask body to meet the needs of subsequent processing steps.

[0033] In this embodiment, the outer cover forming line 2 includes a support platform 38 disposed on one side of the machine base 1, a clamping and traction mechanism 39 disposed on the support platform 38, and an outer cover fabric rack 40, a fabric tensioning and buffering mechanism 41, a front pressing mechanism 42, an outer cover hot pressing forming mechanism 43, a rear pressing mechanism 44, an outer cover cutting mechanism 45, and an output station 46 arranged in a straight line on the support platform 38. The clamping and traction mechanism 39 is movably disposed between the rear pressing mechanism 44 and the outer cover cutting mechanism 45, and the stacking robot 22 is movably disposed between the output station 46 and the inner and outer cover stacking station 21.

[0034] In practical applications, the fabric tensioning and buffering mechanism 41 buffers the outer cover fabric and provides tension, while the clamping and traction mechanism 39 intermittently pulls the outer cover fabric to achieve its movement. When the outer cover hot pressing forming mechanism 43 hot presses the outer cover fabric, the front pressing mechanism 42 and the rear pressing mechanism 44 press the outer cover fabric to ensure the quality of the hot pressing forming on the outer cover fabric. The outer cover cutting mechanism 45 cuts the hot-pressed outer cover fabric into the shape of the outer cover, so that the output station 46 carries a single outer cover body. The stacking robot 22 transfers the single outer cover body to the inner cover body carried by the inner and outer cover stacking station 21 to form an inner and outer cover assembly.

[0035] In this embodiment, the clamping and demolding mechanism 19 includes two clamping and demolding assemblies 47 symmetrically arranged on both sides of the linear circulating conveying device 11. The clamping and demolding assembly 47 includes a stand 48 mounted on the machine base 1, a translation cylinder 49 mounted on the stand 48, a lifting cylinder 50 mounted on the translation end of the translation cylinder 49, a lifting plate 51 mounted on the lifting end of the lifting cylinder 50, a pneumatic gripper 52 mounted on the lifting plate 51, and two clamping plates 53 respectively mounted on the two output ends of the pneumatic gripper 52. The pneumatic gripper 52 is used to drive the two clamping plates 53 to move closer to or further away from each other.

[0036] In practical applications, when the ultrasonically welded inner and outer cover assembly is transported to the clamping and demolding mechanism 19, the two clamping and demolding components 47 clamp the two sides of the inner and outer cover assembly and pull it upward away from the positioning pins 24 of the transport carrier 13 under the coordinated cooperation of the translation cylinder 49, the lifting cylinder 50 and the pneumatic gripper 52. At this time, the transfer robot 20 can pick up the inner and outer cover assembly and transfer it.

[0037] In this embodiment, the pinning mechanism 14 includes a vertical rod 54 mounted on the machine base 1, a pinning cylinder 55 mounted on the vertical rod 54, and a pinning frame 56 mounted on the pinning cylinder 55. The pinning frame 56 has multiple pinning holes 57 around its perimeter, each corresponding to a plurality of positioning pins 24. In practical applications, when the unfolded inner cover fabric moves between the pinning frame 56 and the corresponding conveyor 13, the pinning cylinder 55 drives the pinning frame 56 to move downwards, causing the pinning frame 56 to press the inner cover fabric firmly onto the conveyor 13. The multiple pinning holes 57 engage with the plurality of positioning pins 24, allowing the inner cover fabric to be inserted into the plurality of positioning pins 24.

[0038] In this embodiment, the linear circulating conveying device 11 includes two sets of upper sprocket sets 58 rotatably connected to the machine base 1, two sets of lower sprocket sets 59 rotatably connected to the machine base 1 and located below the two sets of upper sprocket sets 58, a transmission chain 60 meshing and driving the two sets of upper sprocket sets 58 and the two sets of lower sprocket sets 59, and a rotation drive mechanism 61 installed on the machine base 1 for driving at least one set of upper sprocket sets 58 and / or at least one set of lower sprocket sets 59 to rotate. A plurality of conveying carriers 13 are arranged at equal intervals along the length direction of the transmission chain 60.

[0039] In practical applications, the rotation drive mechanism 61 drives at least one set of upper sprockets 58 and / or at least one set of lower sprockets 59 to rotate. The two sets of upper sprockets 58 and the two sets of lower sprockets 59 work together to drive the transmission chain 60 to rotate. The rotating transmission chain 60 drives multiple conveying carriers 13 to rotate cyclically. Since the two sets of upper sprockets 58 and the two sets of lower sprockets 59 are distributed vertically, the transmission chain 60 rotates cyclically in the vertical plane, and the multiple conveying carriers 13 move cyclically in the vertical plane.

[0040] In this embodiment, any mechanism or device not specifically limited (such as folding mechanism 6, unfolding mechanism 9, etc.) can be a mechanism or device in the prior art, and will not be described in detail here.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
