[0032] like Figure 4-5 As shown, this example can achieve a highly efficient effect on plastic fragmentation.

[0033] Since the particle crushing structure for recycling and processing PET foam materials includes a flat plate 101, the flat plate 101 is vertically slidably connected with a door-shaped cover 201, an electric heating wire 202 is arranged on the upper side of the door-shaped cover 201, and limiting blocks 203 are fixed on the front and rear sides of the door-shaped cover 201, the PET foam material can be placed between the door-shaped cover 201 and the flat plate 101, and then the door-shaped cover 201 is heated by the electric heating wire 202, and the door-shaped cover 201 moves downward relative to the flat plate 101, so that the door-shaped cover 201 presses against the PET foam material to quickly compact the PET foam material, thereby facilitating the compression of the PET foam material after recovery, and then efficiently crushing the plastic.

[0034] like Figure 4-5 As shown, this example can achieve the effect of driving the door-shaped cover 201 to rise and fall relative to the flat plate 101.

[0035] Since the lower side of the door-shaped cover 201 is connected to the bottom bar 205 by screws, the lower side of the flat plate 101 is connected to the motor frame 1 204 by screws, the motor is fixed on the motor frame 1 204, the output shaft of the motor is fixed with the screw 206, and the screw 206 and the bottom bar 205 are threadedly matched. The motor drives the screw 206 to rotate, thereby driving the bottom bar 205 to rise and fall, and then driving the door-shaped cover 201 to rise and fall relative to the flat plate 101. When the limit block 203 contacts the flat plate 101, the door-shaped cover 201 cannot continue to move downward.

[0036] like Figure 4-5 As shown, this example can achieve the effect of pushing the compacted PET foam material out from the right side of the door-shaped cover 201.

[0037] Since a support 105 is welded to the left part of the flat plate 101, a slide 104 is slidably connected to the support 105 transversely, a push plate 106 is welded to the right end of the slide 104, and a motor is connected to the left side of the flat plate 101 by screws, and a screw rod 103 is connected to the output shaft of the motor. The screw rod 103 and the left part of the slide 104 are threadedly matched, and the motor drives the screw rod 103 to rotate, thereby driving the slide 104 to slide on the support 105, and then driving the push plate 106 to move rightward, so that the push plate 106 is pressed between the flat plate 101 and the door-shaped cover 201, and then the compacted PET foam material is pushed out from the right side of the door-shaped cover 201, so as to facilitate the next step of crushing the compacted PET foam material.

[0038] like Figure 4-5 As shown, this example can achieve the effect of preventing the PET foam material from leaking out from the left side of the door-shaped cover 201.

[0039] Since the baffle plate 107 is welded on the flat plate 101, the baffle plate 107 fits with the left side of the door-shaped cover 201. When the door-shaped cover 201 moves upward, the distance between the door-shaped cover 201 and the flat plate 101 increases, and the baffle plate 107 can block the upper left side of the door-shaped cover 201, and cooperate with the push plate 106 to block the left side of the door-shaped cover 201, so as to prevent the PET foam material from leaking out from the left side of the door-shaped cover 201.

[0040] like Figure 4-6 As shown, this example can achieve the effect of placing the PET foam material between the flat plate 101 and the door-shaped cover 201 .

[0041] Since the convex shafts 109 are welded on both the front and rear sides of the flat plate 101, the two convex shafts 109 are respectively rotatably connected to the upper parts of the two support rods 110, and the two support rods 110 are welded to the base 301. The flat plate 101 can be rotated on the upper parts of the two support rods 110 through the two convex shafts 109, and then the flat plate 101 can be adjusted to a state where the left side is lower and the right side is higher, so that it is convenient to put the PET foam material between the flat plate 101 and the door-shaped cover 201 after increasing the distance between the flat plate 101 and the door-shaped cover 201, so as to prevent the PET foam material from sliding out from the right side of the door-shaped cover 201, and then it is convenient to compress the PET foam material in the next step.

[0042] like Figure 4-6 As shown, this example can achieve the effect of adjusting the tablet 101 to a state where the left side is lower and the right side is higher.

[0043] Since the block 108 is welded on both the front and rear sides of the flat plate 101, and the two block 108 is respectively fitted with the right sides of the two support rods 110, the weight 102 is welded on the lower left side of the flat plate 101, and the left side of the base 301 is connected with the telescopic rod 1 302 by screws, and the telescopic end of the telescopic rod 1 302 is pressed against the lower left side of the flat plate 101. When the telescopic rod 1 302 is shortened, the left side of the flat plate 101 is affected by the gravity of the weight 102, so that the left side of the flat plate 101 tilts downward, and then the flat plate 101 is adjusted to a state where the left side is lower and the right side is higher. When the flat plate 101 needs to be adjusted to a horizontal state, the telescopic rod 1 302 is driven to extend, and then when the block 108 and the support rod 110 are in contact, the flat plate 101 reaches a horizontal state and cannot continue to rotate clockwise.

[0044] like Figure 4-8 As shown, this example can achieve the effect of crushing the PET foam material pushed out from the door-shaped cover 201.

[0045] Since a plurality of vertical plates 401 are arranged on the right side of the door-shaped cover 201 from front to back, a plurality of triangular heads 402 are arranged on the left side of each vertical plate 401 from top to bottom, the plurality of vertical plates 401 are welded on a sleeve 403, and the sleeve 403 is slidably connected to a cross bar 404. The sleeve 403 can move forward and backward on the cross bar 404, thereby driving the plurality of vertical plates 401 and the plurality of triangular heads 402 to move forward and backward, and then the PET foam material pushed out of the door-shaped cover 201 is crushed by the forward and backward movement of the plurality of triangular heads 402.

[0046] like Figure 6-8 As shown, this example can achieve the effect of conveniently and efficiently crushing the launched PET foam material in multiple directions.

[0047] Since the front and rear ends of the upper side of the cross bar 404 are welded with guide rods 506, the two guide rods 506 are respectively connected to the front and rear ends of the cross bar 501 in a vertical sliding manner, and a top bar 502 is welded between the upper ends of the two guide rods 506. The two guide rods 506 can slide vertically on the cross bar 501, thereby driving the cross bar 404, the sleeve 403 and the plurality of vertical plates 401 to move vertically, thereby making the plurality of triangular heads 402 move up and down, thereby making the plurality of triangular heads 402 move vertically and horizontally, so as to facilitate the multi-directional efficient crushing of the pushed PET foam material.

[0048] like Figure 7-8 As shown, this example can achieve the effect of driving multiple vertical plates 401 and multiple triangular heads 402 to move up and down and back and forth simultaneously.

[0049] Since a slide plate 503 is fixed to the lower side of the top bar 502, the slide plate 503 is vertically slidably connected to the horizontal bar 501, a wave hole 504 is provided at the lower part of the slide plate 503, an L-shaped rod 508 is fixed to the middle part of the sleeve 403, and a vertical groove 507 is provided on the L-shaped rod 508. The round rod 505 is inserted into the wave hole 504 and the vertical groove 507 at the same time, and the round rod 505 can move back and forth, thereby driving the L-shaped rod 508 and the sleeve 403 to move back and forth, thereby driving the multiple When the round rod 505 reciprocates back and forth, it continuously slides on the wave hole 504 on the slide plate 503, and then the slide plate 503 continuously reciprocates up and down, thereby causing the top bar 502, the two guide rods 506, the cross bar 404, the sleeve 403 and the plurality of vertical plates 401 to reciprocate up and down, and then the plurality of vertical plates 401 and the plurality of triangular heads 402 can be driven to reciprocate up and down and back and forth at the same time through the forward and backward movement of the round rod 505.

[0050] like Figure 1-8 As shown, this example can achieve the effect of driving the round rod 505 to move back and forth.

[0051] Since push rods 306 are welded to the front and rear ends of the right side of the horizontal bar 501, the two push rods 306 are respectively slidably connected to the upper parts of the two bars 303, and the two bars 303 are welded to the right end of the base 301. A beam 310 is connected between the two push rods 306 by screws, and a sliding sleeve 304 is slidably connected to the beam 310. The round rod 505 is welded to the left side of the sliding sleeve 304. The beam 310 is connected to the motor frame 2 308 by screws, and the motor is connected to the motor frame 2 308 by screws. A turntable 305 is connected to the output shaft of the motor, and an inclined rod 309 is hinged at the eccentric position of the turntable 305; the other end of the inclined rod 309 is hinged to the sliding sleeve 304. The two push rods 306 can slide left and right on the horizontal bar 501, thereby driving the multiple vertical plates 401 to move left and right, which is convenient for driving the multiple vertical plates 401 to approach or move away from the PET foam material. The motor on the motor frame 308 can drive the turntable 305 to rotate, and then drive the sliding sleeve 304 to move back and forth on the beam 310 through the inclined rod 309, thereby driving the round rod 505 to move back and forth.
