DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0018] Example 1 See also Figure 1-7 , Example 1 provides a four-station production device for shrinking and rolling, which includes a frame 3, four conveying structures 4, two winding structures and a discharge structure 5. The four conveying structures 4 are arranged side by side on the left and right, and are driven synchronously. They are arranged at the top of the frame 3. The two winding structures are arranged side by side on the left and right, and are driven synchronously. They are arranged in the middle of the frame 3. Two conveying structures 4 are correspondingly arranged for each winding structure, that is, one winding structure is correspondingly arranged below the two conveying structures 4 on the left, and another winding structure is correspondingly arranged below the two conveying structures 4 on the right. The discharge structure 5 is located at the rear and lower part of the two winding structures, and is arranged at the lower part of the frame 3. The conveying structure 4, the winding structure and the discharge structure 5 are arranged in sequence from top to bottom. Specifically, one winding structure is arranged on the left side of the frame 3, and the other winding structure is arranged on the right side of the frame 3.

[0019] Among them, the winding structure includes a guiding mechanism, pneumatic scissors, clamping fingers 6, an ejection mechanism 7, a pressing mechanism 8, a discharge trough 9 and a discharge push plate 10. The guiding mechanism, pneumatic scissors, clamping fingers 6 and the pressing mechanism 8 are arranged in sequence from top to bottom and they all process two pieces of curved gauze 1 at the same time to obtain two curved rolls 2. Two conveying structures 4 are correspondingly arranged above each guiding mechanism. The guiding mechanism includes two air blowing pipes arranged side by side in front and back, which is consistent with CN202111661388.1. The two curved gauze 1 pass vertically between the two air blowing pipes. The pneumatic scissors are used to cut the curved gauze 1. The clamping fingers 6 clamp the lower end of the curved gauze 1 and rotate to form a curved roll 2. It is arranged in the left and right directions and can open and close. The ejection mechanism 7 can move left and right, and it can eject the two curved rolls 2 on the clamping fingers 6 to the discharge trough 9. The pressing mechanism 8 is used to press against the lower sides of the two shrink rolls 2 when the winding is about to be completed, so that the shrink rolls 2 are tightened.

[0020] The discharge structure 5 in this embodiment of the present invention is a horizontally arranged discharge rack. Located at the lower rear portion of the frame 3, the discharge rack features multiple round rods arranged side by side, ranging in height from 0.6 to 1.2 meters for ease of operation. The distance between adjacent round rods is less than the diameter of the coil 2 to facilitate access. (The coil 2 is positioned in a front-to-back orientation, positioned between adjacent round rods.)

[0021] The pneumatic shears consist of two longitudinal rails 21, two shear cylinders 22, and two strip cutters 23. The two longitudinal rails 21 are arranged side by side on the frame 3, both oriented in the front-to-back direction. The two strip cutters 23 are driven by two shear cylinders 22 to move toward and away from each other. The left and right ends of the front strip cutter 23 slide in front of the two longitudinal rails 21, while the left and right ends of the rear strip cutter 23 slide in front of the two longitudinal rails 21. The two shrunken gauze sheets 1 pass vertically between the two strip cutters 23. The two shear cylinders 22 are arranged opposite each other, both oriented in the front-to-back direction on the frame 3. The ends of their telescopic rods are connected to the middle of the two strip cutters 23 on opposite sides. The four shear cylinders 22 of the two pneumatic shears are driven synchronously; when the shear cylinders 22 extend, the two strip cutters 23 move toward each other to cut the shrunken gauze sheets 1.

[0022] Among them, the discharge chute 9 is arranged obliquely downward from front to back, with its front part arranged side by side with the clamping fingers 6, and its rear part is located above the discharge structure 5. The side close to the clamping fingers 6 (left or right) is provided with a gap for the bending and rolling 2 and the ejection mechanism 7 (specifically the ejection plate 73) to pass through.

[0023] The discharge push plate 10 is located at the front of the discharge chute 9, in front of the coils 2. It is arranged horizontally and can move backward to eject the two coils 2 in the discharge chute 9. It is driven forward and backward by a push cylinder 11, which is a rectangular plate. The push cylinder 11 is mounted on the frame in a front-to-back direction, with the rear end of its telescopic rod fixedly connected to the discharge push plate 10. The two push cylinders 11 are driven synchronously.

[0024] The clamping finger 6 includes a drive shaft 61, a tension spring 62, a pin 67, two clamping cylinders 63, two rotating plates 64, two fingers 65, and two limit assemblies 66. The two drive shafts 61 of the two clamping fingers 6 are driven synchronously. The four clamping cylinders 63 of the two clamping fingers 6 are driven synchronously. The drive shaft 61 is arranged in the left-right direction and is rotatably mounted on the frame 3. A strip hole is provided in the middle portion in the left-right direction. A drive wheel 69 is coaxially mounted at the end (left or right) away from the discharge chute 9. The strip hole passes through the drive shaft 61 in the front-to-back direction. The pin 67 is arranged vertically and is located at the end (left or right) of the drive shaft 61 closest to the discharge chute 9. The two rotating plates 64 are respectively arranged on the upper and lower sides of the drive shaft 61. They are arranged horizontally, and their middle portions are rotatably mounted at the upper and lower ends of the pin 67. The two clamping cylinders 63 are positioned opposite each other, with the front clamping cylinder 63 located directly in front of the upper rotating plate 64 and the rear clamping cylinder 63 located directly behind the lower rotating plate 64. The clamping cylinders 63 are mounted on the frame 3 in a front-to-back direction. The ends of their telescopic rods are equipped with buffer heads (specifically, rubber columns) located directly in front of or behind the corresponding end of the rotating plate 64 (left or right) away from the discharge chute 9. Two fingers 65 are positioned side by side in a front-to-back arrangement. The front finger 65 is located below the upper rotating plate 64, while the rear finger 65 is located above the lower rotating plate 64. The fingers 65 are arranged in a left-to-right direction, located at the end of the rotating plate 64 (left or right) closest to the discharge chute 9, with their ends (left or right) positioned above the side of the discharge chute 9 (left or right) closest to the clamping fingers 6. Tension spring 62 is arranged in a front-to-back direction, with its front and rear ends connected to opposite sides of the two rotating plates 64, extending through the elongated holes. Two stopper assemblies 66 are provided on each rotating plate 64. Each stopper assembly 66 is provided with an adjustment bolt 68 in the front-to-back direction. This adjustment bolt 68 is an L-shaped plate located at the end of the corresponding rotating plate 64 facing away from the discharge chute 9. One stopper assembly 66 is located at the rear of the upper rotating plate 64, with its adjustment bolt 68 resting against the rear side of the drive shaft 61. The other stopper assembly 66 is located at the front of the lower rotating plate 64, with its adjustment bolt 68 resting against the front side of the drive shaft 61. The degree of closure of the two fingers 65 can be adjusted by rotating the adjustment bolt 68. A first synchronization rod is provided at the lower part of the frame 3 and directly below the drive shaft 61 (driven to rotate by the corresponding structure, which allows the rotating plate 64 to stop when it rotates to the horizontal). The first synchronization rod is arranged in the left and right directions and is respectively connected to the two drive wheels 69 through two first synchronization belts (vertically arranged) to achieve synchronous driving of the two drive shafts 61.

[0025] When the clamping cylinder 63 is extended, its telescopic rod rests against the front or rear side of the corresponding rotating plate 65. At this point, the two fingers 65 open (the rear finger 65 rotates backward, while the upper rotating plate 65 rotates forward; the front finger 65 rotates forward, while the lower rotating plate 65 rotates backward), and the two curved gauze sheets 1 are placed side by side between the two fingers 65. During winding, the two fingers 65 close, clamping the lower ends of the curved gauze sheets 1. The two curved gauze sheets 2 are wound around the left and right sides of the fingers 65, respectively.

[0026] The lower portion of the frame 3 is provided with transverse slide rails 13 running horizontally. Two ejection mechanisms 7 are driven by the same push-pull cylinder 12. The ejection mechanism 7 comprises a slide 71, an ejection cylinder 72, and an ejection plate 73. The push-pull cylinder 12 is positioned horizontally, with its telescopic rod extending out of the cylinder body at either end. The slides of the two ejection mechanisms 7 are located at either end of the telescopic rod of the push-pull cylinder 12 and slide onto the transverse slide rails 13. The ejection plate 73 is positioned in a front-to-back direction, perpendicular to the fingers 65. Its rear portion is provided with a rearward-to-back notch that mates with the fingers 65 (open rearward to accommodate two fingers 65). It is located on the side of the curled roll 2 facing away from the discharge chute 9 (either the left or right side). It can simultaneously eject both curled rolls 2 on the fingers 65 into the discharge chute 9. It is located at the rear end of the telescopic rod of the ejection cylinder 72. The ejection cylinder 72 is positioned in a front-to-back direction and mounted on the slide 71. The two ejection cylinders 72 are driven synchronously. When the ejection cylinders 72 extend, the fingers 65 are positioned in the notches. When the ejection cylinders 72 retract, the ejection plate 73 moves in front of the fingers 65. When the push-pull cylinder 12 drives the ejection mechanism 7 to eject the curved reel 2, the ejection cylinders 72 extend, and the ejection plate 73 moves to directly above the discharge chute 9 and away from the fingers 65.

[0027] Among them, the clamping mechanism 8 is located directly below the two curved rolls 2 on the clamping fingers 6, and it can move upward to press on the lower side of the two curved rolls 2. Specifically, the clamping mechanism 8 includes a clamping cylinder vertically arranged on the frame 3 and a clamping plate at the upper end of its telescopic rod. The clamping plate is arranged in the front-to-back direction, and is arranged obliquely downward from back to front. Its rear part is located directly below the curved roll 2, and the inclination angle of its front part (such as 20-45°) is greater than the inclination angle of its rear part (such as 5-15°). It is arranged side by side with the discharge trough 9. The two clamping cylinders of the two clamping mechanisms 8 are driven synchronously. When the clamping cylinder is extended, the clamping plate presses on the lower side of the curved roll 2.
