Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0035] Example 1

[0036] An acrylic scrap recycling and crushing device, such as Figure 1-Figure 6As shown, it includes a base 1, a support frame 2, a lower hopper 3, a press roller 4, a crushing mechanism 5 and a material receiving mechanism 6. The support frame 2 is fixedly connected to the top of the base 1, and the lower hopper 3 is connected to the middle of the top of the support frame 2. The lower hopper 3 is provided with a crushing mechanism 5, and the crushing mechanism 5 is connected to two press rollers 4. The press rollers 4 can crush the scraps, and the crushing mechanism 5 can provide power to drive the press rollers 4 to rotate. The base 1 is provided with a material receiving mechanism 6, which can collect the crushed materials.

[0037] like Figure 1-Figure 5 As shown, the crushing mechanism 5 includes a double-axis motor 51, a first rotating shaft 52, a second rotating shaft 53 and a column gear 54. The double-axis motor 51 is fixedly connected to the upper rear side of the support frame 2, the first rotating shaft 52 is rotatably connected to the left side of the lower part of the lower hopper 3, the rear end of the first rotating shaft 52 is fixedly connected to the front output shaft of the double-axis motor 51, the right side of the lower part of the lower hopper 3 is rotatably connected to the second rotating shaft 53, the first rotating shaft 52 and the second rotating shaft 53 are respectively fixedly connected to the two pressing rollers 4, the front of the first rotating shaft 52 and the front of the second rotating shaft 53 are fixedly connected to the column gears 54, and the column gears 54 on the left and right sides are meshed with each other.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the material receiving mechanism 6 includes a material receiving hopper 61, a limiting plate 62 and a material receiving basket 63. The limiting plate 62 is fixedly connected to the middle of the top of the base 1, and the material receiving basket 63 is slidably connected inside the limiting plate 62. The material receiving hopper 61 is fixedly connected to the lower part of the support frame 2.

[0039] like Figure 6 As shown, a handle 64 is also included, and the handle 64 is fixedly connected to the middle part of the outer side surface of the material receiving basket 63.

[0040] First, the operator pours the scraps into the lower hopper 3, and the scraps come into contact with the left and right pressing rollers 4, and starts the double-axis motor 51 to work. The double-axis motor 51 drives the first rotating shaft 52 to rotate forward, and the first rotating shaft 52 rotates forward to drive the left pressing roller 4 to rotate forward. At the same time, the first rotating shaft 52 rotates forward to drive the left column gear 54 to rotate forward, and the left column gear 54 rotates forward to drive the right column gear 54 to rotate reversely, and the right column gear 54 rotates reversely to drive the second rotating shaft 53 to rotate reversely, and the second rotating shaft 53 rotates reversely to drive the right pressing roller 4 to rotate reversely. The left and right pressing rollers 4 rotate forward and backward to crush the scraps, and then the materials fall into the receiving basket 63 through the receiving hopper 61. After all the scraps are crushed, the dual-axis motor 51 is turned off, and the first rotating shaft 52 stops driving the second rotating shaft 53 to reverse through the left and right column gears 54. The left and right pressing rollers 4 also stop rotating forward and backward, and then the receiving basket 63 is taken out through the handle 64 for subsequent processing of the materials. After the processing is completed, the receiving basket 63 is put back into the limiting plate 62.

[0041] Example 2

[0042] On the basis of Example 1, Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, it also includes a material twisting mechanism 7, which includes a mounting plate 71, a third rotating shaft 72, a fourth rotating shaft 74, a bevel gear 75, a fixed block 76, a fifth rotating shaft 77 and a material twisting disc 79. A mounting plate 71 is fixedly connected to the middle of the outer rear wall of the support frame 2, and the third rotating shaft 72 is rotatably connected to the upper portion of the mounting plate 71. The third rotating shaft 72 and the rear output shaft of the dual-axis motor 51 are driven by a belt. The front portion of the mounting plate 71 is rotatably connected to the fourth rotating shaft 74, and the upper portion of the fourth rotating shaft 74 and the front portion of the third rotating shaft 72 are both fixedly connected with bevel gears 75, and the two bevel gears 75 are meshed with each other. A fixing block 76 is fixedly connected to the middle and lower portion of the inner rear wall of the support frame 2, and the front portion of the fixing block 76 is rotatably connected to the fifth rotating shaft 77, and the fifth rotating shaft 77 and the fourth rotating shaft 74 are driven by a chain. A material twisting disc 79 is fixedly connected to the upper portion of the fifth rotating shaft 77, and the material twisting disc 79 can further crush the scraps.

[0043] like Figure 1 , Figure 2 , Fig.10 and Fig.11 As shown, it also includes a pressing mechanism 8, which includes a fixed rod 81, a sliding frame 82, a first return spring 83, a pressing block 84, a contact rod 85, a rotating disk 86, a bow rod 87 and a guide plate 88. The fixed rod 81 is fixedly connected to the middle and upper parts of the front and rear side surfaces outside the lower hopper 3, and the sliding frame 82 is slidably connected between the front and rear fixed rods 81. The first return spring 83 is connected between the bottom of the sliding frame 82 and the lower parts of the front and rear fixed rods 81. The contact rod 85 is fixedly connected to the rear side of the sliding frame 82, and the rear output shaft of the dual-axis motor 51 is fixedly connected to the rotating disk 86. The bow rod 87 is symmetrically fixedly connected to the upper and lower sides of the rear side of the rotating disk 86. The outer parts of the upper and lower bow rods 87 are fixedly connected to the guide plates 88. The guide plates 88 can rotate to contact the contact rod 85. A pressing block 84 is fixedly connected to the middle of the sliding frame 82, and the pressing block 84 can press the scraps downward.

[0044] When the double-axis motor 51 is working, the pressing rollers 4 on the left and right sides rotate forward and reverse to cooperate to crush the scraps, and then the materials fall and contact the winch plate 79. At the same time, the double-axis motor 51 drives the third rotating shaft 72 to rotate forward through the belt transmission. The forward rotation of the third rotating shaft 72 drives the fourth rotating shaft 74 to reverse through two bevel gears 75. The reverse rotation of the fourth rotating shaft 74 drives the fifth rotating shaft 77 to reverse through the chain transmission. The reverse rotation of the fifth rotating shaft 77 drives the winch plate 79 to reverse. The winch plate 79 further crushes the materials, and then the materials fall into the receiving basket 63 through the receiving hopper 61. After all the scraps are crushed, the double-axis motor 51 is turned off, and the double-axis motor 51 stops driving the third rotating shaft 72 to rotate forward through the belt transmission, and the winch plate 79 also stops reversing. In this way, it is convenient to further crush the scraps.

[0045] When the double-axis motor 51 is working, the double-axis motor 51 drives the rotating disk 86 to rotate forward, and the rotating disk 86 rotates forward to drive the upper and lower bow rods 87 to rotate forward, and the upper and lower bow rods 87 rotate forward respectively to drive the upper and lower guide plates 88 to rotate forward, and the upper and lower guide plates 88 rotate forward to make the contact rod 85 move up and down, and the first return springs 83 on the front and rear sides play a buffering role. The contact rod 85 moves up and down to drive the sliding frame 82 to move up and down, and the sliding frame 82 moves up and down to drive the pressing block 84 to move up and down, and the pressing block 84 moves up and down to push the scraps downward. After all the scraps are crushed, the double-axis motor 51 is turned off, and the double-axis motor 51 stops driving the upper and lower bow rods 87 to rotate forward through the rotating disk 86, and the pressing block 84 also stops moving up and down. In this way, it can be avoided that the scraps are not in contact with the pressing roller 4, which affects the crushing effect.

[0046] Example 3

[0047] On the basis of Example 1 and Example 2, Figure 1 , Figure 2 and Fig.12 As shown, a cleaning mechanism 9 is also included, and the cleaning mechanism 9 includes a mounting frame 91 and a sponge block 92. The mounting frame 91 is symmetrically fixed to the top of the support frame 2, and the inner sides of the left and right mounting frames 91 are fixed to sponge blocks 92. The left and right sponge blocks 92 are respectively in contact with the left and right pressing rollers 4, and the sponge blocks 92 can clean the pressing rollers 4.

[0048] like Figure 1 , Figure 2 , Fig.13 and Fig.14 As shown, it also includes a limiting mechanism 10, which includes a mounting block 101, a sliding block 102 and a second return spring 103. The mounting block 101 is embedded in the middle of the right part of the limiting plate 62, and the sliding block 102 is slidably connected in the mounting block 101. The sliding block 102 can limit the docking material basket 63, and a second return spring 103 is provided between the right side surface of the sliding block 102 and the inner side surface of the mounting block 101.

[0049] When the left and right nip rollers 4 rotate, the left and right sponge blocks 92 clean the left and right nip rollers 4 respectively to avoid debris remaining on the left and right nip rollers 4 to affect crushing. In this way, excessive debris remaining on the nip rollers 4 can be avoided.

[0050] When the receiving basket 63 is filled with a proper amount of material, the sliding block 102 is pulled to move to the right, the second return spring 103 is compressed, and the sliding block 102 moves to the right to stop the docking basket 63 to limit the position, and then the receiving basket 63 is taken out through the handle 64 for subsequent processing of the material, and the sliding block 102 is released. Due to the action of the second return spring 103, the sliding block 102 moves to the left and resets. After the material processing is completed, the receiving basket 63 is put back into the limiting plate 62 through the handle 64 again. Due to the action of the second return spring 103, the receiving basket 63 will slide over the sliding block 102, and then the sliding block 102 limits the docking basket 63. In this way, the docking basket 63 can be conveniently limited.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
