[0013] The mask forming and welding device in the present invention follows the clamping and includes a frame, a folding mechanism, a welding mechanism, a fixing frame, a telescopic member, a combing mechanism and a conveying mechanism. During assembly, both the welding mechanism and the folding mechanism are fixedly installed on the frame. The welding mechanism and the folding mechanism are arranged adjacent to each other, and the feeding side of the welding mechanism is adjacent to the discharging side of the folding mechanism, which is used for forming and welding the mask after being folded by the folding mechanism. There are two opposite mounting vertical plates and a cover plate on the welding mechanism. The cover plate is erected on the upper ends of the two mounting vertical plates to form a welding frame body. The fixing frame is fixedly installed on the cover plate and extends upward. One end of the telescopic member is rotatably installed on the fixing frame, which is convenient for adjusting the angle of the telescopic member to adapt to different models of products. The combing mechanism is fixedly installed on the moving end of the telescopic member. The position change of the combing mechanism is realized by the position change of the moving end of the telescopic member. First, it approaches the mask ear strap welding point, inserts the combing mechanism between the ear strap and the mask, and then retracts following the movement of the mask. The combing mechanism slowly rises to turn up the ear strap. The conveying mechanism is fixedly installed on the frame. After changing the position of the ear strap, the ear strap enters the conveying mechanism, and the combing mechanism continues to rise and separates from the ear strap, and the forming and welding of the mask is carried out below. Through the above settings, the problems of welding errors and low yield rate during the forming and welding of the mask are avoided.

[0014] The mask forming and welding device in the present invention follows the clamping and includes a mask folding device, a frame, a welding housing, a welding mechanism and an ear strap adjusting mechanism. When installed and used, the welding housing is fixedly installed on the frame, and the welding mechanism horizontally penetrates the welding housing and is fixedly installed on the welding housing, so that the mask fabric passes through the welding mechanism for shaping and welding. The mask folding device is arranged adjacent to the frame and is located on the mask fabric input side of the frame to fold the mask fabric first and then carry out forming and welding. The ear strap adjusting mechanism is fixedly installed on the top of the welding housing through a fixing frame. The telescopic member of the ear strap adjusting mechanism is fixedly installed on the upper end of the fixing frame to push the ear strap combing assembly fixedly installed at the output end to move, move the ear strap combing assembly below the mask ear strap welding point on the mask fabric being conveyed, comb up the ear strap, and at the same time retract following the conveying of the mask fabric to convey the ear strap separately, avoiding welding errors during the forming and welding of the mask fabric. Through the above settings, the position of the ear strap is adjusted and combed during the conveying of the mask fabric, avoiding welding errors during the forming and welding of the mask fabric and resulting in a low yield rate.

[0015] Another technical solution of the present invention is a mask machine, which includes the above-mentioned mask forming and welding device with following clamping, and also includes a nose strip device, an ear strap welding device, a cutting and separating device, and a discharging device.

[0018] The mask machine in the present invention includes a nose strip device, an ear strap welding device, a cutting and separating device, a discharging device, and the above-mentioned mask forming and welding device with following clamping. When installed and used, by sequentially connecting the output ends and input ends of the nose strip device, the ear strap welding device, the mask forming and welding device with following clamping, the cutting and separating device, and the discharging device in an orderly manner, the mask fabric is subjected to the assembly of the nose strip and the contour shaping and welding when passing through the nose strip device, and then enters the ear strap welding device for the welding and installation of the ear straps. The mask fabric with the ear straps installed enters the folding mechanism for symmetric folding and then is input into the mask forming and welding device with following clamping to adjust the position of the mask ear straps and then perform shaping and welding to obtain an uncut formed mask. Finally, the formed mask and the blank fabric are separated by the cutting and separating device, and the mask finished products and waste materials are separately output through the storage device, and finally the mask finished products and waste materials are obtained. Through the above settings, the mask will not have welding errors during the mask forming and welding process in the production process, resulting in defective products. Description of the Drawings

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0036] In the embodiments of the present invention, unless otherwise clearly specified and defined, terms such as "mounted", "connected", "coupled", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0037] In one embodiment of the present invention, as Figures 2 to 5As shown in the figure, a clamping device 10 for mask forming and welding is provided, which includes a frame 11, a folding mechanism 12 and a welding mechanism 13 arranged on the frame 11; two mounting vertical plates 131 are oppositely arranged on the welding mechanism 13, and a cover plate 132 is arranged on the two mounting vertical plates 131. The folding mechanism 12 is used for folding the mask in half, and the welding mechanism 13 is used for welding the mask after folding in half; it also includes a fixing frame 14, a telescopic member 15, a combing mechanism 16 and a conveying mechanism 17; the combing mechanism 16 realizes turning the ear straps upward to change the placement position of the ear straps. The telescopic member 15 pushes the combing mechanism 16 to move on the running path to realize the turning function of the ear straps. The fixing frame 14 is used for assembling the telescopic member 15 and adjusting the angle of the telescopic member 15. The fixing frame 14 is fixedly installed on the top of the conveying mechanism 17 or the cover plate 132 (not shown in the figure) and extends upward. The end of the telescopic member 15 is rotatably installed at the upper end of the fixing frame 14, and the output end of the telescopic member 15 is inclined downward toward the folding mechanism 12. The telescopic member 15 is rotatably installed on the fixing frame 14 and maintains an inclined angle, so that the mobile end can drive the combing mechanism 16 to reach the position of the mask ear straps, and the combing mechanism 16 can complete the turning of the ear straps. The combing mechanism 16 is fixedly installed on the mobile end of the telescopic member 15 and is used to move obliquely downward under the push of the telescopic member 15 and then retract following the movement of the mask to comb the ear straps. The conveying mechanism 17 is arranged between the two mounting vertical plates 131 and above the welding position of the welding mechanism 13. In this process, after the mask fabric is folded in half by the folding mechanism 12, the welding points of the ear straps are changed to both sides. During the movement, the telescopic member 15 pushes the combing mechanism 16 downward, so that the combing mechanism 16 passes through between the ear straps and the mask, and then retracts following the movement of the mask fabric. The combing mechanism 16 slowly rises, turns the ear straps upward, and finally introduces the ear straps into the conveying mechanism 17 for conveying. The combing mechanism 16 continues to rise and separates from the ear straps, and the welding mechanism 13 forms and welds the mask.

[0038] The ear straps of the mask reaching below it are sucked up by the adsorption mechanism, and then lifted upward to leave a space for the combing mechanism 16 to clamp the ear straps and move them toward the conveying mechanism 17. When the ear straps reach the ear strap conveying mechanism 17, they enter the conveying mechanism 17 for conveying. The combing mechanism 16 continues to move and separates from the ear straps. Through the above settings, the position of the ear straps is adjusted to avoid interference of the ear straps with the forming and welding during the forming and welding, and welding errors occur and the ear straps are fixed together.

[0039] The mask forming and welding device in the present invention includes a clamping and picking mechanism 10, which comprises a frame 11, a folding mechanism 12, a welding mechanism 13, a fixing frame 14, a telescopic member 15, a combing mechanism 16 and a conveying mechanism 17. During assembly, both the welding mechanism 13 and the folding mechanism 12 are fixedly installed on the frame 11. The welding mechanism 13 and the folding mechanism 12 are arranged adjacent to each other, and the feeding side of the welding mechanism 13 is adjacent to the discharging side of the folding mechanism 12, which is used for forming and welding the mask after being folded by the folding mechanism 12. Two opposite mounting vertical plates 131 and a mounting plate 172 are provided on the welding mechanism 13. The mounting plate 172 is erected on the upper ends of the two mounting vertical plates 131 to form a welding frame body. The fixing frame 14 is fixedly installed on the mounting plate 172 and extends upward. One end of the telescopic member 15 is rotatably installed on the fixing frame 14, which is convenient for adjusting the angle of the telescopic member 15 to adapt to different models of products. The combing mechanism 16 is fixedly installed on the moving end of the telescopic member 15. The position change of the combing mechanism 16 is realized by the position change of the moving end of the telescopic member 15. First, the ear strap is sucked by the adsorption mechanism, and then the adsorption mechanism moves upward to leave enough space for the combing mechanism 16 to move and pick up the ear strap. The combing mechanism 16 that picks up the ear strap slowly rises with the ear strap to ensure that the ear strap is always in this position. The combing mechanism 16 continues to rise and separates from the ear strap, and the forming and welding of the mask are carried out below. Through the above settings, the problems of welding errors and low yield rate during the forming and welding of the mask are avoided.

[0040] In another embodiment of the present invention, the combing mechanism 16 includes a finger cylinder 161 and two combing strips 162 arranged on the finger cylinder 161. The two combing strips 162 are respectively fixedly connected to the two moving ends of the finger cylinder 161. The two combing strips 162 are used to pick up the ear strap when the combing mechanism 16 moves down to the position of the ear strap, fix the ear strap on the combing strips 162, and move with the upward movement of the combing strips 162 to change the position.

[0041] In another embodiment of the present invention, the combing strip 162 includes a mounting portion and an inserting portion. The two ends of the mounting portion are respectively connected to the moving end of the finger cylinder 161 and the inserting portion, and the inserting portion forms an acute angle with the extension line of the end of the mounting portion. The combing strip 162 is divided into a mounting portion and an inserting portion, and the angle between the connecting end extension line of the inserting portion and the mounting portion is acute, so that the inserting portion can more conveniently insert under the adsorption mechanism to pick up and move the ear strap.

[0042] In another embodiment of the present invention, a first avoidance position 1321 is provided on the mounting plate 172. The ends of the two carding strips 162 both extend into the first avoidance position 1321. The first avoidance position 1321 is arranged at the edge position of the top of the mounting plate 172 and is used to cooperate with the telescopic movement of the movable end of the telescopic member 15. The ends of the carding strips 162 are extended into the first avoidance position 1321 to determine that their movement paths pass through the first avoidance position 1321. And a notch communicating with the first avoidance position 1321 is provided at the edge position of the top of the mounting plate 172. The setting of the notch enlarges the range of the first avoidance position 1321 to facilitate the telescopic movement of the movable end of the telescopic member 15.

The bracket 171 is fixedly installed on the upper surface of the frame 11 and is arranged above the mask conveying path, so that the mask passes through the bracket 171. The mounting plate 172 is arranged at the upper end of the bracket 171. The two belt conveying mechanisms 173 are arranged at the bottom of the mounting plate 172, and the conveying surfaces of the two belt conveying mechanisms 173 are arranged oppositely for clamping and conveying the ear straps. After the belt conveying mechanisms 173 are assembled at the bottom of the mounting plate 172, they are fixedly installed on the bracket 171. The ear straps are clamped and conveyed by the two opposite belt conveying mechanisms 173 assembled at the bottom of the mounting plate 172. At the same time, a second avoidance position 1721 is provided at the ear strap input end of the mounting plate 172 for the carding mechanism 16 to pass through so that the ear straps can be directly input into the belt conveying mechanisms 173 for conveying.

[0044] In another embodiment of the present invention, the belt conveying mechanism 173 includes a plurality of transmission wheels and transmission belts. The transmission wheels are scattered between the two ends of the mounting plate 172, and the transmission belts are wound around the transmission wheels. The transmission wheels drive the transmission belts to move. The two opposite transmission belts abut against each other to convey the ear straps. At the same time, tensioning members are fixedly installed on both sides of the mounting plate 172, and the transmission belts are wound around the tensioning members to adjust the tightness of the transmission belts by using the tensioning members.

[0045] In another embodiment of the present invention, it is characterized in that: a position adjustment component for adjusting the front-back movement of the welding mechanism 13 is provided at the bottom of the welding mechanism 13. The position adjustment component is fixedly installed on the frame 11, and the welding mechanism 13 is fixedly installed on the moving end of the position adjustment component.

The mold and the bottom mold are respectively installed through two installation vertical plates 131, and the mold and the bottom mold are oppositely arranged on both sides of the mask conveying direction and are used for forming and welding the mask. The mask passes between the mold and the bottom mold. After moving a set distance, the mold and the bottom mold on both sides perform shaping and welding on the mask.

[0047] A mask machine provided by another embodiment of the present invention includes the above-mentioned mask forming and welding device with following and clamping 10, and further includes a nose bridge strip device 20, an ear strap welding device 30, a cutting and separating device 40 and a discharging device 50. The output end of the nose bridge strip device 20 is adjacent to the input end of the ear strap welding device 30. The output end of the ear strap welding device 30 is adjacent to the input end of the mask forming and welding device with following and clamping 10. The output end of the mask forming and welding device with following and clamping 10 is adjacent to the input end of the cutting and separating device 40. The output end of the cutting and separating device 40 is adjacent to the input end of the discharging device 50. The mask fabric enters the mask machine from the nose bridge strip device 20. In the nose bridge strip device 20, the nose bridge strip is assembled. The nose bridge strip is placed between multiple layers of fabric, and then the contour of the mask is welded. On the one hand, the position of the nose bridge strip is fixed, and on the other hand, the overall contour of the mask is shaped. Then it is output to the ear strap welding device 30 for the assembly of the ear straps. The mask fabric with the ear straps assembled continues to be conveyed into the mask forming and welding device with following and clamping 10 for folding, adjusting the position of the ear straps and forming and welding. Finally, it is conveyed to the cutting and separating device 40 for separating and cutting the waste. After cutting and separating, the waste and the mask are separately output in the storage device to obtain a single mask or waste.

Then, it enters the ear strap welding device 30 for welding and installation of the ear straps. The mask fabric with ear straps installed enters the folding mechanism for symmetric folding and then is input into the mask forming and welding device with clamping 10. After the position of the mask ear straps is adjusted, forming and welding are carried out to obtain an uncut formed mask.

Finally, the mask finished products and waste materials are obtained. Through the above settings, during the mask forming and welding process in the production of masks, there will be no welding errors, resulting in defective products.

[0049] In another embodiment of the present invention, one end of the conveying mechanism 17 extends above the cutting and separating device 40.
