[0024] Referring to the accompanying drawings, this mask hanging rope connecting machine has a frame 1, a sheet mask conveyor 9, and the conveyor 9 is a conveyor belt. A paddle 10 is arranged on the conveyor belt. A plurality of hanging rope clamping mechanisms 4 with circular transmission are arranged on both sides of the conveyor 9. The hanging rope clamping mechanism 4 includes a pair of clamps 42 that can move up and down, a clamping seat 43 that cooperates with the clamps, and a connecting seat 52. A hanging rope joint welding mechanism is arranged on both sides of the conveyor 9. This hanging rope joint welding mechanism includes an ultrasonic head 2 and a pressure block 3 arranged on both sides of the conveyor 9. The pressure block 3 corresponds to the ultrasonic head 2 and performs intermittent action. There are two working modes of the pressure block 3, one is (such as Figure 1 As shown): the pressing block 3 is equally arranged on a rotating drum 55, and when it rotates to the lowest position, it contacts the ultrasonic head 2, that is, the pressing block 3 contacts the ultrasonic head 2 under the rotation of the rotating drum 55 for welding; another working mode is (as shown Figure 8As shown): the pressing block 3 is mounted on a push rod of a pressing cylinder 56, and relies on the action of the pressing cylinder 56 to cooperate with the ultrasonic head 2 for welding. The hanging rope clamping mechanism 4 has a hanging rope steering device, wherein the hanging rope steering device includes a fixed plate 20 with arc-shaped tracks 21 at both ends, and the fixed plate 20 is arranged on both sides of the conveying path 9. A seat body 57 is connected to the connecting seat 52, and racks 48 are arranged on both sides of the seat body 57. The clamping seat 43 is mounted on the slide 41 through a corresponding rotating shaft 45, and a gear 46 is installed on the rotating shaft 45. The gear 46 is meshed with the rack 48. The slide 41 is slidably connected with the seat body 57 connected to the connecting seat 52, and the slide 41 extends to the lower part of the connecting seat 52 through a bracket 58. The sliding connection is to match the slide 41 with the seat body 57 in the form of a guide rail and a slide groove. A first roller 53 is arranged on the bracket 58, and the first roller 53 can contact the fixed plate 20. When the first roller 53 enters the arc track 21 of the fixed plate 20, under the action of the fixed plate 20, the first roller 53 moves with the bracket 58 and the slide 41, so that the two gears 46 installed on the slide 41 roll on the rack 48, thereby rotating the rotating shaft 45, and rotating the clamping seat 43 and the clamping plate 2 at the same time, and the two clamping seats 43 and the clamping plates 42 rotate in the same direction, rotating the two ends of the clamped hanging rope by 90 degrees to form a "U"-shaped structure, and the ends of the "U"-shaped hanging rope just overlap the two sides of the sheet mask; an intermittently rotating hanging rope cutting mechanism 5 is provided on one side of the path of the circulating transmission, and the hanging rope cutting mechanism 5 includes a rotatable turntable 23, and a cutter seat 14 is evenly arranged on the turntable 23, and a cutter 13 is hinged on the cutter seat 14, and the cutter 13 is connected to a cylinder 12. When the hanging rope is clamped by the hanging rope clamping mechanism, it is transmitted to the hanging rope cutting mechanism 5 during its cyclic transmission. Under the rotation of the turntable 23, the cutter 13 and the cutter seat 14 just rotate to the hanging rope, so that the hanging rope is located between the cutter 13 and the cutter seat 14. Under the action of the cylinder 12, the cutter 13 is pushed. After the cutter 13 and the cutter seat 14 cooperate, the hanging rope can be cut. Under the rotation of the turntable 23 again, the hanging rope is cut again, and the cycle action is repeated.

[0025] The clamping plate 42 is moved up and down by the following scheme: the rope clamping mechanism also has a lifting frame 44, the clamping plate 42 is installed on the clamping seat 43 through a lifting shaft 51, the lifting shaft 51 passes through the clamping seat 43, a touch plate 48 is installed at the bottom end of the lifting shaft 51, a spring 50 is connected between the touch plate 48 and the clamping seat 43, the lifting frame 44 contacts the touch plate 48, the lifting frame 44 can move up and down with the clamping plate 42 through the touch plate 48 and the lifting shaft 51, further, the frame 1 is provided with a pad 22 along the circular transmission track of the rope clamping mechanism, the pad 22 starts from the tail of the rope joint welding mechanism and ends at the rope cutting mechanism 5, and a second roller 47 is provided on the lifting frame 44, and the second roller 47 is placed on the pad 22. Guard plates 49 are arranged on both sides of the lifting frame 44, and the lifting frame 44 and the guard plates 49 are matched in the form of slide rails and slide grooves. During the movement of the rope clamping mechanism 4, when the second roller 47 rolls onto the pad 22, the lifting frame 44 rises, and the clamping plate 42 rises through the touch plate 48 and the lifting shaft 51, so that the clamping plate 42 and the clamping seat 43 are in an open state, and the rope passes between the clamping plate 42 and the clamping seat 43. At this time, the spring 50 between the touch plate 48 and the clamping seat 43 is in a stretched state; when the second roller 47 rolls down the pad 22, due to the action of gravity, the lifting frame 44 moves downward due to its own weight, and the clamping plate 42 also moves downward, and under the return action of the spring 50, the rope is clamped. Since each rope clamping mechanism is provided with two clamping plates 42 and the clamping seat 43, this clamping mechanism can clamp the two ends of the rope after cutting, and a "U"-shaped structure will be formed under the action of the rope steering device.

[0026] The rope clamping mechanism 4 is cyclically driven in the following manner: a synchronous belt 18 is provided on the frame 1, and in this embodiment, the eight rope clamping mechanisms 4 are installed on the synchronous belt 18 through a connecting seat 52. With the transmission of the synchronous belt 18, the rope clamping mechanism 4 is cyclically driven. An elliptical guide rail 16 parallel to the synchronous belt 18 is provided on the outer side of the synchronous belt 4, and two bearings 17 are installed on the connecting seat 52, and the elliptical guide rail 16 is placed between the two bearings 17. In this way, the rope clamping mechanism 4 is stably moved along the elliptical guide rail 16 without deviation.

[0027] A third synchronous belt 59 is also provided above the conveying path 9. The third synchronous belt 59 is fitted to the conveying path 9, which not only flattens the sheet-shaped mask but also facilitates the welding of the hanging rope.

[0028] The working principle of the present invention is described below: In order to save space for description, the rope clamping mechanism 4, welding mechanism, cutting mechanism 5 and circulating transmission method on both sides of the conveying path 9 of the present invention are symmetrically arranged on both sides of the conveying path, and only the working method of one side will be described below.

[0029] In order to maintain the synchronization of the transmission of the present invention, a motor 24 is used to drive a total transmission shaft 25. First bevel gears 26 and 27 are provided at both ends of the total transmission shaft 25, and a synchronous belt 18 is wound around the main synchronous wheel 11 and the auxiliary synchronous wheel 15. A second bevel gear 28 and a second synchronous wheel are respectively installed on the rotating shaft 60 of the main synchronous wheel 11, wherein a third synchronous wheel 30 is installed on the rotating shaft of the turntable 23, and the second synchronous wheel and the third synchronous wheel 30 are connected by a second synchronous belt 29. The first bevel gear 27 is meshed with the second bevel gear 28. When the motor 24 is working, it drives the turntable 23 to rotate and drives the synchronous belt 18 in a circular manner. The rope is rolled up on one side of the rope cutting mechanism 5. When the rope clamping structure 5 is transmitted to one side of the rope cutting mechanism 5, the second roller 47 is still placed on the pad 22, and the clamping plate 42 and the clamping seat 43 are in an open state. After the rope passes through the two clamping plates 42 and the clamping seat 43 of a clamping mechanism, as the rope clamping mechanism 4 moves, the second roller 47 drops off the pad 22. After the lifting frame 44 falls, under the action of the spring 50, the clamping plate 42 of the rope clamping mechanism 4 falls on the clamping seat 43 to clamp the rope. When a rope clamping structure 4 clamps the rope, it moves to the rope cutting mechanism 5. At this time, the turntable 23 of the rope cutting structure 5 just rotates to, and under the action of the cylinder 12, the rope is cut off. Of course, the rope is cut off at the tail end of the last clamping plate and the clamping seat of the rope clamping structure. Then, under the movement of the synchronous belt 18, the transmission of the rope clamping mechanism 4 is transmitted to the fixed plate 20, and the first roller 53 thereon enters the arc track 21 of the fixed plate 20. Under the action of the arc track 21, the slide 41 of the rope clamping mechanism 4 starts to move, and the two gears 46 on the slide 41 roll on the racks 48 on both sides of the seat body 57, so that the clamping seat 43 and the clamping plate 42 rotate at the same time, and the two clamping seats and clamping plates rotate 90 degrees in the same direction to form a "U"-shaped structure of the rope, and the conveyor 9 continuously conveys the sheet-shaped masks formed by the mask forming machine into place. At this time, the ports of the "U"-shaped structure are just overlapped on both sides of the sheet-shaped mask, and the overlap point is just located above the ultrasonic head 2. At the same time, under the rotation of the rotating drum 55, the pressing block 3 rotates to the lowest position, and after cooperating with the ultrasonic head 2, the rope is welded to the sheet-shaped mask. Or when welding, under the action of the pressing cylinder 56, the pressing block 3 is pushed to cooperate with the ultrasonic head 2 to weld the hanging rope to the sheet mask. The cyclic conveying of the hanging rope clamping mechanism and the intermittent work of the pressing block 3 can continuously weld the sheet mask conveyed from above, greatly improving its production efficiency.
