DETAILED DESCRIPTION
[0021] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.
[0022] like Figure 1 As shown, a clothes dryer filter folding tool includes a belt conveyor 400. Two sets of filter folding devices are installed along the conveying direction of the belt conveyor 400. Each set of filter folding devices can automatically fold a clothes dryer filter. If needed, three or more sets of filter folding devices can be provided to further improve the efficiency of the clothes dryer filter folding work.
[0023] like Figure 1 As shown, each set of filter folding devices includes a first clamping assembly 100 and a second clamping assembly 200 that are symmetrically arranged on the left and right sides. The first clamping assembly 100 and the second clamping assembly 200 are respectively detachably connected to the left and right frames of the belt conveyor 400. The first clamping assembly 100 and the second clamping assembly 200 can cooperate to clamp the left and right sides of the dryer filter.
[0024] like Figure 1 As shown, the second clamping assembly 200 is provided with a folding assembly 300, which can drive the unclamped portion of the dryer filter to fold back and forth multiple times to prevent the hinge from breaking when closing. If needed, the folding assembly 300 can also be provided on the first clamping assembly 100.
[0025] like Figure 2 and Figure 3 As shown, the first clamping assembly 100 includes a first mounting plate 101, which is removably connected to the frame of the belt conveyor 400 via multiple bolts. A first telescopic cylinder 102, mounted horizontally and removably connected to the first mounting plate 101 via multiple bolts, is mounted horizontally. The driving end of the first telescopic cylinder 102 is connected to a first telescopic plate 103, which can move the first telescopic plate 103 toward or away from the side of the dryer filter located on the belt conveyor 400. A first clamping cylinder 107 is secured to the first telescopic plate 103. The two clamping ends of the first clamping cylinder 107 are each connected to a first clamping block 108, which can cooperate to clamp the dryer filter. The side of the first clamping cylinder 107 is detachably connected to the first mounting bracket 109 by bolts, and the first limiting rod 110 is fixedly connected to the first mounting bracket 109. The front end of the first limiting rod 110 is provided with a first anti-collision rubber head 111. When the first clamping cylinder 107 clamps the dryer filter, the front end of the first limiting rod 110 can contact and position the side of the dryer filter, and the first anti-collision rubber head 111 can avoid damage to the dryer filter.
[0026] like Figure 2 and Figure 3As shown, a first guide mechanism is disposed between the first mounting plate 101 and the first telescopic plate 103. The first guide mechanism guides the forward and backward telescopic movement of the first telescopic plate 103. The first guide mechanism comprises two first guide sleeves 104 fixed to the first mounting plate 101, symmetrically arranged about the first telescopic cylinder 102. A first guide rod 105 is disposed within the first guide sleeves 104. One end of the first guide rod 105 is fixedly connected to the first telescopic plate 103, while the other end extends out of the first guide sleeves 104 and connects to a first stopper 106. The first stopper 106 prevents the first guide rod 105 from slipping out of the first guide sleeves 104.
[0027] like Figure 4 and Figure 5 As shown, the second clamping assembly 200 includes a second mounting plate 201, which is removably connected to the frame of the belt conveyor 400 via multiple bolts. A second telescopic cylinder 202 is horizontally mounted on the second mounting plate 201 and removably connected via multiple bolts. The driving end of the second telescopic cylinder 202 is connected to a second telescopic plate 203, which can move the second telescopic plate 203 toward or away from the side of the dryer filter located on the belt conveyor 400. A second clamping cylinder 207 is secured to the second telescopic plate 203. The two clamping ends of the second clamping cylinder 207 are each connected to a second clamping block 208, which can cooperate to clamp the dryer filter. The side of the second clamping cylinder 207 is detachably connected to the second mounting bracket 209 by bolts, and the second mounting bracket 209 is fixedly connected to the second limiting rod 210. The front end of the second limiting rod 210 is provided with a second anti-collision rubber head 211. When the second clamping cylinder 207 clamps the dryer filter, the front end of the second limiting rod 210 can contact and position the side of the dryer filter, and the second anti-collision rubber head 211 can avoid damage to the dryer filter.
[0028] like Figure 4 and Figure 5 As shown, a second guide mechanism is disposed between the second mounting plate 201 and the second telescopic plate 203. This second guide mechanism guides the forward and backward telescopic movement of the second telescopic plate 203. The second guide mechanism includes two second guide sleeves 204 fixed to the second mounting plate 201, symmetrically arranged about the second telescopic cylinder 202. A second guide rod 205 is disposed within the second guide sleeves 204. One end of the second guide rod 205 is fixedly connected to the second telescopic plate 203, while the other end extends out of the second guide sleeves 204 and connects to a second stopper 206. This stopper 206 prevents the second guide rod 205 from slipping out of the second guide sleeves 204.
[0029] like Figure 4 and Figure 5 As shown, the folding assembly 300 includes a flip cylinder 302. The cylinder body of the flip cylinder 302 is rotatably connected to a cylinder bracket 303 via a pin. The cylinder bracket 303 is fixed to the second telescopic plate 203 of the second clamping assembly 200. The driving end of the flip cylinder 302 is rotatably connected to one end of a flip plate 301 via a pin. The flip plate 301 is rotatably connected to the second telescopic plate 203 of the second clamping assembly 200 via a rotating shaft. The flip plate 301 is detachably connected to a fork arm 304 via a bolt. The front end of the fork arm 304 can fork the side of the dryer filter. When the flip cylinder 302 is in operation, it can drive the flip plate 301 to rotate about the rotating shaft, thereby driving the fork arm 304 to rotate, and the fork arm 304 then drives the dryer filter to fold.
[0030] like Figure 4 and Figure 5 As shown, a first limiting block 306 and a second limiting block 309 are respectively fixed to the flip plate 301. A first limiting bolt 307 is threadedly connected to the first limiting block 306, and a second limiting bolt 310 is threadedly connected to the second limiting block 309. A first limit block 305 is provided in the rotation path of the first limiting block 306, and the first limit block 305 is fixed to the second telescopic plate 203. A second limit block 308 is provided in the rotation path of the second limiting block 309, and the second limit block 308 is fixed to the second telescopic plate 203. The first limiting bolt 307 on the first limiting block 306 cooperates with the first limit block 305 to limit the highest position that the flip plate 301 can reach when it flips. The second limiting bolt 310 on the second limiting block 309 cooperates with the second limit block 308 to limit the lowest position that the flip plate 301 can reach when it flips.
[0031] The working principle of the present invention is as follows: Before folding the dryer filter A, a robotic arm removes the hot, freshly injection-molded dryer filter from the mold and places it on a belt conveyor 400. The belt conveyor 400 transports the dryer filter to the filter folding device. The filter folding device then begins operation. First, the first clamping assembly 100 and the second clamping assembly 200 cooperate. The first clamping cylinder 107 and the second clamping cylinder 207 extend and respectively clamp the left and right sides of one side of the dryer filter hinge. Simultaneously, the fork arm 304 of the folding assembly 300 extends and clamps one side of the dryer filter hinge. The flipping cylinder 302 then rotates the flip plate 301 about the axis, thereby rotating the fork arm 304, which in turn causes the dryer filter to repeatedly fold. After injection molding, the dryer filter is repeatedly folded back and forth while still hot to prevent breakage at the hinge when closing. After the folding process, the belt conveyor 400 transports the dryer filter A to the next process.
