[0029] like Figures 1 to 3 As shown, a filter screen winding device 10 includes a base 100 and a winding assembly 200. The winding assembly 200 includes a feeding belt 210, a drive roller 220, a driven roller 230, and a rotary drive component 240. The feeding belt 210 is rotatably mounted on the base 100, and the drive roller 220 is rotatably mounted on the base 100, with one end of the drive roller 220 connected to the feeding belt 210. The driven roller 230 is adjustablely mounted on the base 100. The outer wall of the movable roller 230 rolls against the outer side of the drive roller 220. The rotary drive 240 is mounted on the base 100, and the feed belt 210 and the drive roller 220 are both connected to the output shaft of the rotary drive 240. The rotary drive 240 is used to simultaneously drive the feed belt 210, the drive roller 220, and the driven roller 230 to rotate, so that the filter screen is fed by the feed belt 210 between the drive roller 220 and the driven roller 230 for winding.

[0030] It should be noted that the feed belt 210 is rotatable on the base 100 and is used to transfer the filter screen. The drive roller 220 is rotatably mounted on the base 100 via bearings, and one end of the drive roller 220 is connected to the feed belt 210. Furthermore, the driven roller 230 is adjustablely mounted on the base 100 and is used to roll against the drive roller 220. Thus, the rotary drive 240 drives the feed belt 210, drive roller 220, and driven roller 230 to rotate simultaneously, causing the filter screen on the feed belt 210 to pass between the drive roller 220 and the driven roller 230, so that the filter screen is rolled and wound into a cylindrical shape, which facilitates the subsequent welding of the filter screen into the annular groove 21 of the valve core 20.

[0031] likeFigure 1 As shown in FIG. 1, in an embodiment, the base 100 comprises a partition plate 110 and two side plates 120, the two side plates 120 are respectively arranged on the two sides of the partition plate 110, the feeding belt 210, the driving roller 220 and the driven roller 230 are located between the two side plates 120, and the rotary driving member 240 is located on the side of the side plate 120 away from the partition plate 110.

[0032] It should be noted that the base 100 is composed of the partition plate 110 and the two side plates 120 respectively arranged on the two sides of the partition plate 110, so that the feeding belt 210 is located between the two side plates 120. The two ends of the driving roller 220 are rotatably connected with the two side plates 120. The two ends of the driven roller 230 are adjustably located relative to the two side plates 120.

[0033] As shown in FIG. 2, in an embodiment, the partition plate 110 comprises a middle interface 111 and a discharging inclined surface 112, the feeding belt 210 and the driving roller 220 are respectively located at the two ends of the middle interface 111, and the discharging inclined surface 112 is located below the driving roller 220. Figure 2

[0034] It should be noted that the partition plate 110 is located between the feeding belt 210 and the driving roller 220, so that the middle interface 111 is connected with the feeding belt 210 and the driving roller 220 respectively. Further, the discharging inclined surface 112 is located below the driving roller 220. In this way, after the filter screen on the feeding belt 210 is transferred to the middle interface 111, and then rolled and pressed by the driving roller 220 and the driven roller 230, the cylindrical filter screen slides out of the discharging inclined surface 112.

[0035] As shown in FIG. 3, in an embodiment, the material winding assembly 200 further comprises a material pushing wheel 251, the two ends of the material pushing wheel 251 are rotatably connected with the two side plates 120 respectively, and the material pushing wheel 251 is located above the middle interface 111. Figure 2

[0036] It should be noted that when the filter screen is transferred from the feeding belt 210 to the middle interface 111, in order to avoid the filter screen staying on the middle interface 111, the material pushing wheel 251 is arranged to rotate on the middle interface 111, so as to push the filter screen into the driving roller 220 and the driven roller 230. In an embodiment, the material pushing wheel 251 is a cam mechanism, so that as the material pushing wheel 251 rotates, the convex part can stably bring the filter screen into the driving roller 220 and the driven roller 230.

[0037] As shown in FIG. 4, in an embodiment, the rotary driving member 240 comprises a driving motor 241 and a driving shaft 242, the driving motor 241 is arranged on the side plate 120, the driving shaft 242 is rotatably connected with the driving motor 241, and the driving shaft 242 is rotatably connected with the material pushing wheel 251. Figures 1 to 3 ​​As shown, in an embodiment, the roll assembly 200 further comprises a pressure regulating shaft 252, two ball bearings 253 and two pressure regulating screws 254, each of the two side plates 120 is provided with a waist-shaped hole 121, the two ends of the pressure regulating shaft 252 are respectively arranged through the two waist-shaped holes 121, the two ball bearings 253 are sleeved on the pressure regulating shaft 252, the two ball bearings 253 are respectively in rolling connection with the material pushing wheel 251 and the driven roller 230, and the two pressure regulating screws 254 are respectively screwed on the two side plates 120 and respectively extend into the two waist-shaped holes 121 to abut against the two ends of the pressure regulating shaft 252.

[0038] It should be noted that, in order to enable the material pushing wheel 251 to stably follow the rotation, the structure of the present embodiment is provided. Specifically, the pressure regulating shaft 252 passes through the waist-shaped holes 121 in the two side plates 120, the two ball bearings 253 are sleeved on the pressure regulating shaft 252, and the pressure regulating screws 254 are screwed on the two side plates 120 to extend into the two waist-shaped holes 121. In this way, the two ends of the pressure regulating shaft 252 are pushed by the pressure regulating screws 254, so that the two ball bearings 253 installed on the pressure regulating shaft 252 can reliably roll with the material pushing wheel 251 and the driven roller 230. In this way, as the driven roller 230 rotates, the material pushing wheel 251 rotates in the same direction through the ball bearings 253.

[0039] As shown, Figures 1 to 3 In an embodiment, the base 100 is provided with a fixed rotating wheel 261, the base 100 is provided with a sliding block 262 which slides, the sliding block 262 is provided with a sliding rotating wheel 263 which rotates, the feeding belt 210 is sleeved on the sliding rotating wheel 263 and the fixed rotating wheel 261, and the base 100 is further provided with a top block 264 which rotates, the top block 264 is used to push the sliding block 262 to drive the sliding rotating wheel 263 to move away from the fixed rotating wheel 261 when the top block 264 is forced to rotate, so as to tighten the feeding belt 210.

[0040] It should be noted that the fixed rotating wheel 261 is installed on the base 100 through a bearing, so that the fixed rotating wheel 261 can stably rotate on the base 100. The sliding block 262 is slidingly installed on the base 100, for example, a sliding groove is formed on the base 100, and the sliding block 262 is slidingly installed in the sliding groove in a fitting manner, so that the sliding block 262 can slide along the sliding groove to approach or move away from the fixed rotating wheel 261. The sliding rotating wheel 263 is rotatably installed on the sliding block 262 through a bearing. The feeding belt 210 is sleeved on the fixed rotating wheel 261 and the sliding rotating wheel 263. The top block 264 is rotatably installed on the base 100. It should be noted that a protruding portion is arranged on the outer side wall of the top block 264, when the top block 264 is forced to rotate, the protruding portion of the top block 264 pushes the sliding block 262, so that the sliding rotating wheel 263 moves away from the fixed rotating wheel 261, and the feeding belt 210 is tightened. In this way, when the feeding belt 210 is worn, it is convenient to replace it.

[0041] AsFigure 3 As shown, in an embodiment, a locking pin 265 is also inserted into the base 100, and a locking hole 2641 is formed in the top block 264. The locking pin 265 is used to pass through the locking hole 2641 so that the top block 264 is clamped with the base 100.

[0042] It should be noted that in order to make the protruding part of the top block 264 stably hold the sliding block 262, the locking hole 2641 is formed in the top block 264, so that the locking pin 265 can pass through the locking hole 2641 to clamp and fix the top block 264 with the base 100. That is, the top block 264 cannot continue to rotate under the clamping effect of the locking pin 265, so that the feeding belt 210 is stably kept in a taut state.

[0043] As shown in Figure 1 and Figure 4 In an embodiment, the rotary driving member 240 includes a rotary motor 241, a power gear 242, and two slave gears 243. The rotary motor 241 is arranged on the base 100, the power gear 242 is arranged on the output shaft of the rotary motor 241, one of the two slave gears 243 is coaxially arranged with the driving roller 220, and the other is coaxially arranged with the fixed roller 261. Both of the two slave gears 243 are engaged with the power gear 242.

[0044] In this way, the rotary motor 241 drives the power gear 242 to rotate, so that the two slave gears 243 rotate synchronously, thereby driving the driving roller 220 and the fixed roller 261 to rotate. The filter element is driven by the feeding belt 210 to enter the middle interface 111, and the driven roller 230 is engaged with the driving roller 220, so it also rotates. The ball bearing 253 drives the stirring wheel 251 to rotate, so that the filter screen of the middle interface 111 is reliably sent into the driven roller 230 and the driving roller 220 to be rolled into a cylindrical structure.

[0045] As shown in Figures 1 to 4 In an embodiment, the base 100 is slidably provided with a pressure adjusting block 271, and the driven roller 230 is rotatably arranged on the pressure adjusting block 271. The base 100 is also screwed with a pressure adjusting rod 272, one end of which is rotatably connected with the pressure adjusting block 271. When the pressure adjusting rod 272 is forced to rotate relative to the base 100, the pressure adjusting rod 272 pushes the pressure adjusting block 271, so that the pressure adjusting block 271 drives the driven roller 230 to be engaged with the driving roller 220.

[0046] It needs to be explained that in order to make the rolling pressure between the driven roller 230 and the driving roller 220 adjustable, the above structure is provided. Specifically, the pressure adjusting block 271 can slide relative to the base 100, and the driven roller 230 is mounted on the pressure adjusting block 271 through a bearing, so that the driven roller 230 can rotate relative to the pressure adjusting block 271. The pressure adjusting rod 272 is screwed with the base 100, and the end of the pressure adjusting rod 272 is rotationally connected with the pressure adjusting block 271. In this way, as the pressure adjusting rod 272 is forced to rotate relative to the base 100, the pressure adjusting block 271 slides relative to the base 100, thereby reliably rolling the driven roller 230 with the driving roller 220, ensuring that the driving roller 220 and the driven roller 230 can reliably roll the filter screen into a cylindrical shape.

[0047] As shown in Figure 1 and Figure 4 shown, in an embodiment, the base 100 is provided with a U-shaped groove 130, and the pressure adjusting block 271 is slidingly arranged in the U-shaped groove 130. In this way, the U-shaped groove 130 limits the pressure adjusting block 271 to slide along the U-shaped groove 130, so that the outer side wall of the driven roller 230 can reliably roll with the driving roller 220.

[0048] As shown in Figure 5 , in an embodiment, the filter screen winding device 10 is used in conjunction with the cutting machine 30. For example, the filter screen winding device 10 can be installed at the discharge port of the cutting machine, so that after the cutting machine 30 cuts the wound filter screen into small pieces and a flat structure, the filter screen falls on the feeding belt 210 and is moved by the feeding belt 210 to the driving roller 220 and the driven roller 230 to be rolled into a cylindrical shape.
