The large end of the second piston shaft is slidably arranged in the second piston cylinder, and its small end penetrates through the second piston cylinder.

[0025] The present invention further provides a production process of an environment-friendly board, using the above-mentioned production equipment for the environment-friendly board. The specific steps are as follows:

[0026] S1. Put the recycled waste plastic into the housing. When the waste plastic is soft plastic, the movable end of the adjusting component moves towards the first kneading part. The plastic is located between the adjusting component and the first kneading part. Start the driving component to drive the first kneading part to move towards the rectangular shell. At this time, the driving and squeezing mechanism aggregates the soft plastic towards the first kneading part.

[0027] S2. Rub the waste plastics into strips through the friction between the first kneading part and the adjusting component.

[0028] S3. When the waste plastics are barrel-shaped plastics, such waste plastics are relatively large. The movable end of the adjusting component moves away from the first kneading part. Then, the air inside the adjusting component is extruded and squeezed into the inner cavity of the piston cylinder two along the connecting pipe assembly. The piston shaft two at the bottom of the inner cavity of the piston cylinder two is compressed, and the bottom end of the piston shaft two extends out of the first kneading part. When the first kneading part moves towards the direction of the rectangular shell, the bottom end of the piston shaft two slides within the guiding part, so that the piston shaft two reciprocates along the guiding part. The piston shaft two then drives the piston cylinder two to reciprocate, and then drives the conical spikes to reciprocate through the piston cylinder two, so as to pierce the barrel-shaped material through the conical spikes and perform pre-crushing.

[0029] S4. The processed plastics enter the inner cavity of the equipment body from the bottom end of the outer shell, and then are crushed by the equipment body. The plastic particles after crushing are discharged from the bottom of the equipment body, and then are melted, formed and surface-treated to produce environment-friendly plates.

[0030] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0031] When processing soft plastics, the distance between the first kneading part and the second kneading part is in the initial state. Start the first driving device to drive the first kneading part to move towards the second kneading part. Knead the soft plastics into strips through the first kneading part and the second kneading part, and drive the cutting knife to reciprocate through the reciprocating rod reciprocating along the guiding part, so that the cutting knife is located within the cutting groove and reciprocates to cut the soft plastics into strips and fall into the equipment body. When processing barrel-shaped plastics, the second driving device drives the piston shaft one on the second kneading part to move towards the direction of the first spring, and after the piston shaft one passes over the ventilation hole, the air inside the piston shaft one is squeezed into the inner cavity of the piston cylinder two along the first round pipe and the second telescopic pipe, so as to drive the piston shaft two in the inner cavity of the piston cylinder two to move downward, so that the bottom of the piston shaft two extends out of the inner cavity of the piston cylinder two, and further enables the piston shaft two to drive the piston cylinder two to reciprocate along the guiding part, so as to drive the conical spikes to reciprocate to crush the barrel-shaped material. Furthermore, when processing soft plastics, the soft plastics can be kneaded into strips, the volume of the soft plastics is reduced, the mass per unit volume is increased, and the barrel-shaped material is crushed, avoiding the situation that these plastics slip inside the equipment body.

[0051] The moving seat 6 is in contact with the inner wall of the protruding shell 3. When the lead screw 5 drives the moving seat 6 to move, the inner wall of the protruding shell 3 positions and guides the moving seat 6, and then drives the first kneading part 7 to move towards the direction of the rectangular shell 34 through the moving seat 6.

[0052] The adjusting component includes a second driving device 8, a second kneading part 9, a first piston shaft 10, a first piston cylinder 11, a first spring 12 and a ventilation hole 13;

[0053] The second driving device 8 is installed on the outer shell 2. The second kneading part 9 is movably connected to the second driving device 8 and faces the first kneading part 7.

[0054] After the first piston shaft 10 passes over the vent hole 13, the part between the inner cavity of the first piston cylinder 11 and the first piston shaft 10 becomes a sealed state, so that the first piston shaft 10 can extrude the air in the inner cavity of the first piston cylinder 11 along the first round tube 14.

[0055] The connecting pipe assembly includes the first round tube 14 and the second telescopic tube 15;

The two ends of the first elastic part 21 are respectively connected to the second piston cylinder 16 and the first kneading part 7. Air enters the second piston cylinder 16 from the second telescopic tube 15, driving the second piston shaft 18 to descend and extend out of the inner cavity of the second piston cylinder 16. When the first kneading part 7 drives the second piston shaft 18 to move, the second piston shaft 18 moves along the guiding part 22, driving the conical thorn 20 on the second piston cylinder 16 to reciprocate and break the barrel-shaped plastic.

[0059] The cutter assembly includes the second elastic part 23, the reciprocating rod 24, the cutting groove 25, the cutting knife 26, the telescopic part 27, the traveling wheel 28 and the traveling groove 29;

Compared with Embodiment 1, the feeding mechanism of this embodiment includes a feeding wheel 30, a transmission member 31, a gear 32 and a rack 33;

[0063] The feeding wheel 30 is rotatably arranged at the connection of the inclined surface and the flat surface of the first kneading part 7.

[0065] Embodiment 3, as Figure 1 and Figure 2 shown, a production device for an environment-friendly board proposed by the present invention. Compared with Embodiment 2, this embodiment further includes a telescopic guide plate 35 and an inclined plate 19;

[0066] Both sides of the telescopic guide plate 35 are hinged to the housing 2 and the second kneading part 9 respectively. The telescopic guide plate 35 expands and contracts with the movement of the second kneading part 9. The inclined plate 19 is installed in the housing 2 and is located above the guiding part 22.

[0067] The recycled plastic is put in from the upper part of the housing 2. First, it is blocked by the telescopic guide plate 35 and guided between the second kneading part 9 and the first kneading part 7, and then the upper part of the guiding part 22 is protected by the inclined plate 19.

[0068] Example 4, as Figures 1 - 10 shown, for the production process of an environment-friendly board proposed by the present invention, compared with Example 3, the specific steps of this example are as follows:

[0069] S1. Put the recycled waste plastic into the outer shell 2. When the waste plastic is soft plastic, the movable end of the adjusting component moves towards the first kneading part 7, and the plastic is located between the adjusting component and the first kneading part 7. Start the driving component to drive the first kneading part 7 to move towards the rectangular shell 34. At this time, the driving and squeezing mechanism aggregates the soft plastic towards the first kneading part 7.

[0070] S2. Knead the waste plastic into strips through the friction between the first kneading part 7 and the adjusting component. The bottom end of the cutter component slides in the guiding part 22 and reciprocates along the guiding part 22 to cut the kneaded soft plastic into segments. The kneaded and segmented soft plastic enters the inner cavity of the equipment body 1 for crushing.

[0071] S3. When the waste plastic is barrel-shaped plastic, this kind of waste plastic is relatively large. The movable end of the adjusting component moves away from the first kneading part 7. Then, the air in the adjusting component is extruded and squeezed into the inner cavity of the second piston cylinder 16 along the connecting pipe component. The piston shaft 2 of the bottom of the inner cavity of the second piston cylinder 16 is compressed, and the bottom end of the piston shaft 2 extends out of the first kneading part 7. When the first kneading part 7 moves towards the rectangular shell 34, the bottom end of the piston shaft 2 slides in the guiding part 22, so that the piston shaft 2 reciprocates along the guiding part 22. The piston shaft 2 then drives the second piston cylinder 16 to reciprocate, and then drives the conical thorn 20 to reciprocate through the second piston cylinder 16, so as to pierce the barrel-shaped material through the conical thorn 20 and perform preliminary crushing.

[0072] S4. The processed plastic enters the inner cavity of the equipment body 1 from the bottom end of the outer shell 2, and then is crushed by the equipment body 1. The crushed plastic particles are discharged from the bottom of the equipment body 1, and then are melted, formed and surface-treated to produce an environment-friendly board.

[0073] In summary, in the present invention, the recycled waste plastic is put into the outer shell 2. When the waste plastic is soft plastic, the driving device 2 drives the second kneading part 9 to move towards the first kneading part 7, and the plastic is located between the second kneading part 9 and the first kneading part 7. Start the driving device 1 to drive the lead screw 5 to rotate. The lead screw 5 drives the moving seat 6 to drive the first kneading part 7 to move towards the rectangular shell 34 along the axis direction of the lead screw 5. First, the gear 32 meshes with the rack 33, so as to drive the gear 32 to rotate. The gear 32 drives the feeding wheel 30 to rotate through the transmission part 31, and then aggregates the soft plastic towards the second kneading part 9 through the feeding wheel 30, thus avoiding the situation that some plastics with a large loose area are not all kneaded.

[0074] Subsequently, the first kneading part 7 and the second kneading part 9 knead the soft plastic into a strip, and most of the first kneading part 7 enters the inner cavity of the rectangular shell 34. During the movement of the first kneading part 7, the bottom end of the reciprocating rod 24 enters the guiding groove of the guiding part 22 and reciprocates along the guiding part 22. The reciprocating rod 24 drives the cutting knife 26 to reciprocate. The cutting knife 26 moves into the inner cavity of the cutting groove 25 and cuts off the soft plastic kneaded into a strip. Then, the first driving device 4 drives the first kneading part 7 to reset. At this time, the baffle plate in the inner cavity of the outer shell 2 blocks the soft plastic, causing it to fall into the equipment body 1 for crushing.

[0075] When the recycled plastic is barrel-shaped plastic, the second driving device 8 is started to drive the second kneading part 9 to move towards the direction of the first piston cylinder 11, thereby driving the first piston shaft 10 to move towards the direction of the first spring 12 in the inner cavity of the first piston cylinder 11, increasing the distance between the first piston shaft 10 and the second kneading part 9 relative to when processing soft plastic, so that the barrel-shaped plastic just gets stuck between the second kneading part 9 and the inclined plate 19. After the first piston shaft 10 moves past the ventilation hole 13, the first piston shaft 10 squeezes the air in the inner cavity of the first piston cylinder 11 along the ventilation hole 13 into the inner cavities of the first circular tube 14 and the second telescopic tube 15, and then enters the inner cavity of the second piston cylinder 16 along the first circular tube 14 and the second telescopic tube 15, thereby driving the second piston shaft 18 at the bottom end of the second piston cylinder 16 to extend out of the inner cavity of the second piston cylinder 16. When the first kneading part 7 moves towards the direction of the rectangular shell 34 again, the second piston shaft 18 enters the guiding groove of the guiding part 22, and the guiding part 22 guides the second piston shaft 18, enabling the second piston shaft 18 to reciprocate, thereby driving the second piston cylinder 16 to reciprocate. The second piston cylinder 16 drives the conical spikes 20 to reciprocate, breaking the barrel-shaped plastic and making it fall into the inner cavity of the equipment body 1. Thus, when processing soft plastic, the soft plastic is kneaded into a strip, and when processing barrel-shaped plastic, the barrel-shaped plastic can be broken and fall into the inner cavity of the equipment body 1, avoiding the situation where the crushing knife in the inner cavity of the equipment body 1 slips due to these lighter plastics.

[0076] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to this. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
