[0036] Embodiment 1

[0037] With reference to Figures 1 to 6 as shown, this embodiment discloses a specific implementation of a composite reverse osmosis membrane welding device.

[0038] Regarding the composite reverse osmosis membrane welding device, with reference to Figures 1 to 6As shown, the assembly includes an upper welding component 2 and a lower welding component 3 driven by a bidirectional lead screw 1 for opening and closing. The upper welding component 2 includes a pair of elongated first transverse welding heads 21 and a pair of elongated first longitudinal welding heads 22. The lower welding component 3 includes a pair of elongated second transverse welding heads 31 and a pair of elongated second longitudinal welding heads 32. Two parallel first welding strips 211 are provided on the surface of the first transverse welding heads 21, two parallel second welding strips 311 are provided on the surface of the second transverse welding heads 31, and two parallel third welding strips 311 are provided on the surface of the first longitudinal welding heads 22. The surface of the second longitudinal welding head 32 is provided with two parallel fourth welding strips 321; a pair of first transverse welding heads 21 and a pair of second transverse welding heads 31 cooperate to form a first transverse weld mark 41 and a second transverse weld mark 42 distributed front and back of the composite film 4; a pair of first longitudinal welding heads 22 and a pair of second longitudinal welding heads 32 cooperate to form a first longitudinal weld mark 43 and a second longitudinal weld mark 44 distributed left and right of the composite film 4; the first transverse weld mark 41, the second transverse weld mark 42, the first longitudinal weld mark 43 and the second longitudinal weld mark 44 form a rectangular weld mark.

[0039] Specifically, see Figures 1 to 6 The continuous composite membrane material advances intermittently, each time advancing one step distance; see also Figure 4 ,Will Figure 4 The visible composite membrane material 4 is divided into a first range 45, a second range 46 and a third range 47. The purpose of this embodiment is to first form a first transverse weld mark 41 and a second transverse weld mark 42 in each predetermined range of the composite membrane material 4, and then form a first longitudinal weld mark 43 and a second longitudinal weld mark 44, thereby forming a rectangular weld mark, which provides a basis for subsequent cutting into filter material.

[0040] See Figures 1 to 6 The first transverse weld mark 41 and the second transverse weld mark 42 each include two parallel first weld marks 411 and second weld marks 412, with a gap between the first weld mark 411 and the second weld mark 412. The first longitudinal weld mark 43 and the second longitudinal weld mark 44 each include two parallel third weld marks 431 and fourth weld marks 432, with a gap between the third weld mark 431 and the fourth weld mark 432, so that two weld marks with a gap are formed around the perimeter of each predetermined range of composite film material 4.

[0041] See Figures 1 to 6Temperature sensors are installed in the first transverse welding head 21, the first longitudinal welding head 22, the second transverse welding head 31, and the second longitudinal welding head 32. These sensors allow for the real-time monitoring of the temperatures of the first welding strip 211, the second welding strip 311, the third welding strip 221, and the fourth welding strip 321. Welding is performed when the temperatures of these three welding strips reach between 170°C and 200°C. Since the time it takes for the first welding strip 211, the second welding strip 311, the third welding strip 221, and the fourth welding strip 321 to reach the welding temperature may differ, the welding is performed first on the strips reaching the 170°C-200°C range, and then on the strips that reach that temperature. After the welding strip is welded, welding is performed. The upper welding assembly 2 also includes an upper support plate 23, and the lower welding assembly 3 also includes a lower support plate 33. The upper support plate 23 is equipped with a third lifting cylinder 231 and a fourth lifting cylinder 232. The third lifting cylinder 231 drives the first transverse welding head 21 to rise and fall, and the fourth lifting cylinder 232 drives the first longitudinal welding head 22 to rise and fall. The welding process of the composite film 4 is as follows: the continuous composite film 4 advances intermittently, each time advancing one step; in the first step, the bidirectional screw 1 drives the upper welding assembly 2 and the lower welding assembly 3 to move away from each other, and the continuous composite film 4 is placed between the upper welding assembly 2 and the lower welding assembly 3. The first range 45 is aligned with a pair of first transverse welding heads 22. First, the second range 46 aligns the welding head 21 and the pair of second transverse welding heads 31 with the pair of first longitudinal welding heads 22 and the pair of second longitudinal welding heads 32. Second, the bidirectional lead screw 1 drives the upper welding assembly 2 and the lower welding assembly 3 to approach and close each other. The third lifting cylinder 231 drives the first transverse welding head 21 to descend, and the fourth lifting cylinder 232 drives the first longitudinal welding head 22 to descend. The first transverse welding head 21, the first longitudinal welding head 22, the second transverse welding head 31, and the second longitudinal welding head 32 begin heating. According to the order in which the predetermined welding temperature of 170℃-200℃ is reached, the third lifting cylinder 231 and the fourth lifting cylinder 232 return to their original positions in sequence. In this way, the welding head that reaches the welding temperature first is lifted by the cylinder first, and the welding head that reaches the welding temperature later is lifted later, so as to avoid welding defects such as over-welding (too high temperature) or under-welding (insufficient temperature) caused by inconsistent temperatures of some welding heads; for example, if the temperature of the first transverse welding head 21 and the second transverse welding head 31 at the front end of the composite film material 4 reaches the welding temperature of 170℃-200℃ first, then the third lifting cylinder 231 will drive the first transverse welding head 21 back to its position first; in the third step, the cold air cooling component 5 near the returned welding head is activated. After all the welding heads have returned to their positions, the bidirectional screw 1 drives the upper welding component 2 and the lower welding component 3 to move away from each other, and the cold air cooling component 5 continues to cool each welding head to 70℃-80℃.In the fourth step, the composite membrane 4 advances one step, the second range 46 advances to the position of the first range 45, and the third range 47 advances to the position of the second range 46. Steps one through three are repeated. The first transverse weld mark 41, the second transverse weld mark 42, the first longitudinal weld mark 43, and the second longitudinal weld mark 44 form a rectangular weld mark on the composite membrane 4 in the second range 46. Meanwhile, the composite membrane 4 in the third range 47 is welded left and right to form the first longitudinal weld mark 43 and the second longitudinal weld mark 44.

[0042] See Figures 1 to 6 The working principle of the cold air cooling component 5 is as follows: Cold air cooling components 5 are provided near the first horizontal welding head 21, the first vertical welding head 22, the second horizontal welding head 31, and the second vertical welding head 32. The cold air cooling component 5 includes a cold air plate 51 and a cold air pipe 52. The cold air plate 51 is in a vertical state. The cold air plate 51 is provided with a row of first air outlets 511. The cold air pipe 52 is provided with a row of second air outlets 521. Several first air outlets 511 and several second air outlets 521 are aligned with the corresponding first horizontal welding head 21, first vertical welding head 22, second horizontal welding head 31, and second vertical welding head 32. That is, cold air is blown out and faces the corresponding welding head from the upper side (such as the second air outlet 521) and the lower side (such as the first air outlet 511) on one side of each welding head, so as to achieve the purpose of rapid cooling.

[0043] See Figures 1 to 6 After welding, to prevent the composite film 4 from adhering to the surface of the welding head, the upper support plate 23 is equipped with a first detachment component 24. The first detachment component 24 includes a first lifting cylinder 241 and a lower pressure plate 242 driven by the first lifting cylinder 241. The lower pressure plate 242 can press the composite film 4 downward and detach it from the welding head (first transverse welding head 21 or first longitudinal welding head 22). The lower support plate 33 is equipped with a second detachment component 34. The second detachment component 34 includes a second lifting cylinder 341 and an upper pressure plate 342 driven by the second lifting cylinder 341. The upper pressure plate 342 can push the composite film 4 upward and detach it from the welding head (second transverse welding head 21 or first longitudinal welding head 22). (First transverse welding head 21 or second longitudinal welding head 32); To further improve the cooling efficiency of the welding heads (first transverse welding head 21, first longitudinal welding head 22, second transverse welding head 31, second longitudinal welding head 32), the lower pressure plate 242 is provided with a row of third air outlets (not shown), and the upper pressure plate 342 is provided with a row of fourth air outlets (not shown); Through this design, on the basis of cooling the upper and lower sides of each welding head by cold air, the other side of the first transverse welding head 21 and the first longitudinal welding head 22 is cooled by cold air from the third air outlet, and the other side of the second transverse welding head 31 and the second longitudinal welding head 32 is cooled by cold air from the fourth air outlet.
