For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood in combination with specific circumstances.
[0042] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0043] The embodiment relates to a kind of foam product crushing recycling device, as shown in Figure 1 Overall structure, including pulverizer 1, pulverizer 1 is divided into upper box 101 and lower box 102.
[0044] The side of the top of upper box 101 is provided with feed inlet, and two transverse parallel rotating rollers 2 are arranged in upper box 101, and pulverizing blocks 201 are arranged on the outer periphery of each rotating roller 2. The rotating direction of the two rotating rollers 2 is opposite, and the pulverizing blocks 201 on the two rotating rollers 2 are staggered along the length direction of the rotating roller 2. When the two rotating rollers 2 rotate, each pulverizing block 201 can crush the foam product and transport the foam product to the lower box 102. A first rotating shaft 1021 is vertically arranged in the lower box 102, and a pulverizing cutter head 3 is arranged on the first rotating shaft 1021. A first motor 1022 connected to the first rotating shaft 1021 is arranged at the bottom of the lower box 102, and a discharge pipe 103 communicating with the lower box 102 is arranged.
[0045] As described above, by arranging the pulverizing blocks 201 on the rotating rollers 2 and the pulverizing cutter head 3, when the two rotating rollers 2 rotate, the staggered pulverizing blocks 201 can engage the foam product and cut the foam product into smaller pieces. Then, the foam product enters the lower box 102 and is cut by the high-speed rotating pulverizing cutter head 3, further crushing the foam product, effectively improving the particle size of the crushed foam product, thereby improving the crushing effect of the foam product, so as to facilitate the subsequent recycling of the crushed foam product.
[0046] Based on the above overall introduction, specifically, from Figure 1 the left side of the rotating roller 2 is clockwise, and the rotating roller 2 on the right side is counterclockwise, so that the crushing block 201 can engage the foam product and drag it into the crushing box 1. Specifically, as an embodiment of driving the rotating roller 2 to rotate, the rotating shafts of the two rotating rollers 2 in the embodiment can extend to the outside of the upper box body 101, and the two rotating shafts are respectively connected to two intermeshing gears. When any rotating roller 2 is driven to rotate, the other rotating roller 2 can be driven to rotate through the gears. Of course, other embodiments can also be used, for example, two driving motors are used to simultaneously drive the two rotating rollers 2 to rotate, which can drive the two rotating rollers 2 to rotate.
[0047] In the embodiment, the crushing cutter 3 includes a disc-shaped connecting portion 301, and a plurality of blades 302 extending outward from the edge of the connecting portion 301. Each blade 302 is arranged around the connecting portion 301, and adjacent two blades 302 are respectively inclined upward and downward. Through the inclined arrangement of the blades 302, the cutting area of the crushing cutter 3 is improved, thereby improving the cutting effect of the crushing cutter 3 on the foam product.
[0048] Further, the lower box body 102 in the embodiment is funnel-shaped, and the crushing cutter 3 is configured as a plurality of spaced-apart along the length direction of the first rotating shaft 1021. Each blade 302 gradually decreases in diameter from top to bottom, and the end of each blade 302 is close to the side wall of the lower box body 102. It can be understood that the funnel-shaped lower box body 102 can collect the foam product fragments to the center of the lower box body 102, and the plurality of crushing cutters 3 can improve the cutting times of the foam product. At the same time, the end of each blade 302 is close to the side wall of the lower box body 102, so that the foam product can be continuously cut by the blade 302 during the process of being concentrated to the center of the lower box body 102, to further improve the granularity of the foam product and improve the crushing effect.
[0049] Since the first motor 1022 is arranged at the bottom of the lower box body 102, the discharge pipe 103 can only be arranged on one side of the first motor 1022, so that part of the foam product fragments may remain in the lower box body 102. In order to ensure that the foam product in the lower box body 102 can enter the discharge pipe 103, the first rotating shaft 1021 in the embodiment is provided with a plurality of baffles 1023, and the lower edge of the baffle 1023 abuts against the bottom of the lower box body 102. When the first rotating shaft 1021 rotates, the baffle 1023 can abut against the bottom of the lower box body 102 and push the foam product fragments to the discharge pipe 103, so that the foam product fragments can be prevented from remaining in the lower box body 102, and the crushed foam product can be easily discharged.
[0050] In addition, the lower box 102 of the embodiment is provided with a screen 1031 at the connection position of the discharge pipe 103, and the upper surface of the screen 1031 is flush with the bottom of the lower box 102. Through the arrangement of the screen 1031, the foam product fragments are crushed to a certain particle size before entering the discharge pipe 103 through the screen 1031, so as to ensure the crushing effect of the foam product. In specific implementation, the screen 1031 is clamped at the connection position of the discharge pipe 103 and the lower box 102.
[0051] As a specific implementation form, as shown in Figure 2 , Figure 3 In order to further improve the crushing effect of the foam product, the embodiment also includes a crushing disc mechanism, which includes a shell 4 connected to the discharge pipe 103, a static disc 5 fixed in the shell 4, and a dynamic disc 6 rotatingly arranged in the shell 4. The static disc 5 and the dynamic disc 6 are coaxially arranged, the static disc 5 is provided with a through hole 501, and the foam product can enter between the static disc 5 and the dynamic disc 6 through the through hole 501. The static disc 5 and the dynamic disc 6 are respectively provided with a static tooth ring 7a and a dynamic tooth ring 7b formed by a plurality of cutting teeth 7 distributed at intervals, and the cutting teeth 7 on the static tooth ring 7a and the dynamic tooth ring 7b at least partially overlap in the radial direction. When the dynamic disc 6 rotates, each cutting tooth 7 can shear the foam product, and the bottom end of the shell 4 is provided with a discharge port 401. Therefore, through the arrangement of the crushing disc mechanism, the foam product can be cut and crushed into particles with higher particle size through the rotation of the dynamic tooth ring 7b and the static tooth ring 7a, and the size difference of the particles is reduced, thereby reducing the difficulty and cost of subsequent processing.
[0052] In specific implementation, the side of the shell 4 close to the dynamic disc 6 is provided with a third motor 402, the output shaft of the third motor 402 is coaxially connected with the dynamic disc 6, and the third motor 402 can drive the dynamic disc 6 to rotate at high speed to effectively crush the foam product.
[0053] Specifically, each cutting tooth 7 is distributed between the static disc 5 and the dynamic disc 6 in the radial direction, in order to make the foam product move in the radial direction and be cut by the cutting tooth 7, the central side of the dynamic disc 6 of the embodiment towards the static disc 5 is provided with a conical structure 601. Through the arrangement of the conical structure 601, the conical structure 601 can push the foam product to move in the radial direction, and the rotation of the dynamic disc 6 makes the foam product close to the cutting tooth 7 under the centrifugal action, so as to ensure that the foam product can be effectively cut and crushed.
[0054] Further, the static disc 5 and the dynamic disc 6 are both provided with grinding gear rings 8. The two grinding gear rings 8 are oppositely arranged, and there is a gap between the two grinding gear rings 8 in the direction that the dynamic disc 6 is spaced from the static disc 5, and the gap is used for discharging the foam product. Specifically, the surface of any grinding gear ring 8 towards the other grinding gear ring 8 has a toothed structure, and when the foam product fragments enter between the two grinding gear rings 8, the foam product fragments can be sheared and rubbed by the grinding gear rings 8, so that the foam product fragments are further crushed into granular, and until the diameter of the granular foam product is less than or equal to the gap between the two grinding gear rings 8, the granular foam product is discharged from between the dynamic disc 6 and the static disc 5, so as to crush the foam product into granular, further improve the crushing effect, and ensure the granularity consistency of the foam product granules.
[0055] In order to convey the foam product into the crushing disc mechanism, the conveying device is arranged between the discharge pipe 103 and the shell 4 of the embodiment, which comprises a transversely arranged conveying channel 9, a second rotating shaft 901 rotatably arranged in the conveying channel 9, and a spiral blade 902 arranged on the second rotating shaft 901. One end of the conveying channel 9 is closed, and the other end is communicated with the shell 4. The outer side of the closed end of the conveying channel 9 is provided with a second motor 903 connected with the second rotating shaft 901, and the discharge pipe 103 is connected at the top of the conveying channel 9. Through the arrangement of the spiral blade 902 in the conveying channel 9, the spiral blade 902 can push the foam product to the dynamic disc 6 and the static disc 5, so as to ensure that the foam product passes through the through hole 501 and is conveyed to the dynamic disc 6 and the static disc 5 for crushing.
[0056] Finally, the feeding port of the embodiment is provided with a guide chute 1011, which extends obliquely downward from the outer side of the upper box body 101 to the inside of the upper box body 101, so as to facilitate the pouring of the foam product to be crushed and recycled into the crushing box 1. The feeding port of the embodiment is also provided with a baffle 1012, which prevents the foam product fragments crushed by the rotating roller 2 and the crushing cutter disc 3 from overflowing from the feeding port.
[0057] In summary, the foam product crushing and recycling device of the embodiment can crush the foam product into small fragments through the crushing blocks 201 on the rotating roller 2 and the crushing cutter disc 3. When the two rotating rollers 2 rotate, the staggered crushing blocks 201 can bite the foam product and shear the foam product into small fragments. Then, the foam product enters the lower box body 102 and is cut by the high-speed rotating crushing cutter disc 3, so as to further crush the foam product, effectively improve the granularity of the crushed foam product, and improve the crushing effect of the foam product, so as to facilitate the subsequent recycling of the crushed foam product, and has good practicability.
