Description

Technical Field

[0001] This utility model relates to a beat-and-wind device. Background Technology

[0002] Currently, reverse osmosis membranes are the core component for achieving reverse osmosis. During membrane production, multiple layers of membrane material need to be wound onto a central tube. For example, a reverse osmosis membrane production line winding device disclosed in Chinese Patent No. CN214421853U can wind multiple layers of membrane material onto a central tube. However, because the multiple layers of membrane material are stacked, gas can be trapped between adjacent layers, and wrinkles can occur in the membrane material. Existing winding devices cannot expel the trapped gas or eliminate wrinkles during winding, resulting in the membrane material wound onto the central tube also containing gas and wrinkles, ultimately leading to substandard product quality.

Simultaneously, the tapping drive mechanism 6 drives the tapping component 5 to reciprocate, causing it to tap the film material 8 connected to the central tube 7. Figure 2 As shown, the tapping component 5 taps the portion of the film material 8 that has not yet been wound onto the central tube 7. Specifically, the repeated tapping of the film material 8 by the tapping component 5 is similar to the repeated tapping of the film material 8 by a human hand. Through tapping, the air trapped in the film material 8 can be expelled during the winding process, and the wrinkles in the film material 8 can be eliminated. This allows the film material 8 to be wound onto the central tube 7 smoothly and tightly, thereby improving the quality of the product after winding.

[0074] like Figures 1-4 As shown, the slapping component 5 may include a rotating shaft 9, a swing arm 10, and a slapping plate 11;

[0075] The rotating shaft 9 is rotatably connected to the lifting seat 3;

[0076] The swing arm 10 is connected to the rotating shaft 9;

[0077] The slapping plate 11 is connected to the swing arm 10, and the slapping drive mechanism 6 is connected to the rotating shaft 9 and is used to drive the rotating shaft 9 to reciprocate, thereby driving the swing arm 10 and the slapping plate 11 to swing back and forth, thereby repeatedly slapping the film material 8 through the slapping plate 11; in this embodiment, multiple swing arms 10 are arranged in parallel.

The drive source 12 is connected to the lifting seat 3 and is used to drive the drive disk 13 to rotate, thereby driving the swing rod 15 to swing through the transmission rod 14, and thus driving the slapping component 5 to swing back and forth. Specifically, the drive source 12 can be a geared motor, the drive disk 13 can be connected to the motor shaft of the geared motor, and one end of the swing rod 15 is connected to the rotating shaft 9 in the slapping component 5.

[0084] The lower pressure roller 16 is rotatably connected to the lifting seat 3 and located below the central tube 7 clamped in the winding mechanism 2;

[0085] The lifting drive 4 is used to drive the lifting seat 3 to move upward, thereby driving the lower pressure roller 16 to rise and press the film material 8 wound on the central tube 7. Specifically, when the lifting drive 4 drives the lifting seat 3 to rise to the position, the lower pressure roller 16 abuts against the film material 8 wound on the central tube 7, thereby enabling the film material 8 to be wound more tightly and flatly on the central tube 7.

The drive source 12 in the slapping drive mechanism 6 is connected to the first lifting plate 17. A magnetic powder brake is connected to the second lifting plate 18. The magnetic powder brake is connected to the lower pressure roller 16 through a synchronous belt mechanism.

[0092] like Figure 1 , 2 As shown, the beating and winding device may further include an upper pressure roller 22, a pressure seat 23, and a pressing cylinder 24;

[0093] The pressure base 23 is slidably connected to the frame 1 in the vertical direction;

[0094] The upper pressure roller 22 is rotatably connected to the pressure base 23 and is located above the central tube 7 clamped in the winding mechanism 2;

[0095] The pressing cylinder 24 is connected to the frame 1. The pressing cylinder 24 is connected to the pressing base 23 and is used to drive the pressing base 23 to move downward, thereby driving the upper pressure roller 22 to press the film material 8 wound on the central tube 7, so as to further make the film material 8 more compact and flatly wound on the central tube 7. In this embodiment, there are two upper pressure rollers 22.

[0096] like Figures 6-9 As shown, the winding mechanism 2 may include a first slide 25, a top rod 26, a first drive cylinder 27, a second slide 28, a rotating seat 29, a tension clamp 30, a second drive cylinder 31, a tension drive mechanism, and a winding drive assembly.

[0097] The first slide block 25 is slidably connected to the frame 1 in the left-right direction;

[0098] The push rod 26 is connected to the first slide block 25;

[0099] The first drive cylinder 27 is connected to the frame 1 and connected to the first slide 25. The first drive cylinder 27 is used to drive the first slide 25 to move, thereby driving the push rod 26 to move to one end of the central tube 7.

[0103] The expansion drive mechanism is connected to the expansion clamp 30 and is used to drive the expansion clamp 30 to expand radially outward, thereby expanding the central tube 7;

[0104] The winding drive assembly is connected to the second slide 28 and the rotating seat 29. The winding drive assembly drives the rotating seat 29 to rotate, thereby rotating the tensioning clamp 30 and the tensioned central tube 7. Specifically, the first drive cylinder 27 drives the first slide 25 to move towards the central tube 7, thereby moving the push rod 26 to press against one end of the central tube 7. The second drive cylinder 31 drives the second slide 28 to move towards the central tube 7, thereby moving the tensioning clamp 30 to extend into the other end of the central tube 7. The tensioning drive mechanism drives the tensioning clamp 30 to expand outwards, thereby tensioning the central tube 7, so that one end of the central tube 7 is pressed against and the other end is tensioned and clamped. Then, the winding drive assembly drives the rotating seat 29 to rotate, which in turn drives the tensioning clamp 30 to rotate, which in turn drives the tensioned central tube 7 to rotate. When the central tube 7 is rotated, the film material 8 connected to the central tube 7 can be wound onto the central tube 7. In this embodiment, both the first drive cylinder 27 and the second drive cylinder 31 are pneumatic cylinders. The push rod 26 can be fixedly connected to the first slide block 25. When the central tube 7 rotates, one end of the central tube 7 will rotate relative to the push rod 26. Of course, in some embodiments, the push rod 26 can also be rotatably connected to the first slide block 25. In this case, when the central tube 7 rotates, it will drive the push rod 26 to rotate together.

When the winding motor 33 drives the driving pulley 34 to rotate, it can drive the driven pulley 35 to rotate through the transmission component 36, thereby driving the rotating seat 29, the tensioning clamp 30 and the tensioned central tube 7 to rotate.

[0111] like Figures 7-9 As shown, the expansion clamp 30 may include a main body 37, an expansion head 38, an elastic ring 39 and at least two expansion blocks 40, and the expansion drive mechanism may include a pull rod 41 and a rotary cylinder 42;

[0112] The main body 37 is connected to the rotating seat 29 and is coaxially arranged with the rotating seat 29;

[0114] The expansion blocks 40 are arranged sequentially between the main body 37 and the expansion head 38 along the circumference of the pull rod 41. The second drive cylinder 31 is used to drive the second slide block 28 to move toward the central tube 7, thereby driving the expansion head 38, the expansion blocks 40 and the main body 37 to extend into the central tube 7.

[0115] The elastic ring 39 is sleeved on the outside of the expansion blocks 40 arranged sequentially along the circumference and is used to hold the expansion blocks 40 arranged sequentially along the circumference.

[0119] Specifically, when the second drive cylinder 31 drives the second slide block 28 to move toward the central tube 7, it can drive the expansion head 38, the expansion block 40 and a part of the main body 37 to extend into the central tube 7. Then, the rotary cylinder 42 drives the pull rod 41 to move, thereby driving the expansion head 38 to move toward the main body 37. At this time, through the cooperation of the first drive inclined surface 43 and the first mating inclined surface 45 and the cooperation of the second drive inclined surface 44 and the second mating inclined surface 46, the expansion block 40 can be driven to expand radially outward, thereby causing the expansion block 40 to press against the inner wall of the central tube 7 and thus tighten the central tube 7. Then the winding drive assembly drives the rotating seat 29 to rotate. When the rotating seat 29 rotates, it will drive the main body 37, the tensioning block 40, the tensioning head 38, the tensioned central tube 7, the pull rod 41 and the rotating part of the rotary cylinder 42 to rotate together, while the fixed part of the rotary cylinder 42 will not rotate. When the central tube 7 rotates, the film material 8 connected to the central tube 7 can be wound onto the central tube 7.

[0120] More specifically, the rotary cylinder 42 is existing technology, for example, it can be a medium-density pneumatic rotary cylinder disclosed in Chinese Patent No. CN210164710U; wherein, the fixed part of the rotary cylinder 42 includes the bearing seat in the patent, the rotating part of the rotary cylinder 42 includes the cylinder body in the patent, and the telescopic part of the rotary cylinder 42 includes the piston shaft in the patent; more specifically, the bearing seat can be connected to the second slide 28 through the bracket plate, the cylinder body can be connected to the rotating seat 29, and the piston shaft can be connected to the tail of the pull rod 41.

The pull rod 41 passes sequentially through the main body 37, the first seat body 47, the second seat body 48, the third seat body 49, and the fourth seat body 50. The collet is a locking device for holding cutting tools, commonly used on drilling and milling machines and machining centers. The specific structure of the collet is existing technology and will not be described in detail in this embodiment.

[0122] Specifically, the tensioning block 40 is provided with a slot for the elastic ring 39 to be inserted into, and the elastic ring 39 is used to hold the tensioning blocks 40 arranged in sequence along the circumference; in this embodiment, there are three tensioning blocks 40 evenly distributed along the circumference, and the first driving inclined surface 43 and the second driving inclined surface 44 correspond one-to-one with the tensioning block 40.

[0123] like Figure 8 As shown, the tightening head 38 is sleeved on the head of the pull rod 41. The head of the pull rod 41 is provided with an abutment boss 51 that protrudes radially outward. The tightening head 38 is provided with a step portion 52 for abutting against the abutment boss 51.

[0124] In summary, the central tube 7 is clamped in the winding mechanism 2, causing the lifting drive 4 to drive the lifting seat 3 to rise into position. The winding mechanism 2 drives the central tube 7 to rotate to wind up the film material 8 connected to the central tube 7. Simultaneously, the slapping drive mechanism 6 drives the slapping component 5 to oscillate back and forth, causing the slapping component 5 to slap the film material 8 connected to the central tube 7. The slapping component 5 slaps the portion of the film material 8 that has not yet been wound onto the central tube 7. The repeated slapping of the film material 8 by the slapping component 5 is similar to the repeated slapping of the film material 8 by a human hand. Through slapping, air trapped in the film material 8 can be expelled during the winding process, and wrinkles in the film material 8 can be eliminated. This allows the film material 8 to be wound onto the central tube 7 smoothly and tightly, improving the quality of the product after winding.
