[0002] Foamed plastics are a kind of light and porous materials, which are widely used in the fields of packaging, construction, transportation, etc. The waste foam formed after use belongs to a kind of recyclable material and can be recycled by reprocessing, pyrolysis and other methods. Based on the uneven shapes and volumes of waste foams, before deep treatment, they need to be compressed into blocks to facilitate transportation and storage. Among them, during the briquetting process, whether it is heating or crushing, harmful gases will be generated. Therefore, heating and crushing operations need to obtain relevant environmental assessment qualifications before they are allowed to be carried out. The existing briquetting machines that can be seen on the market mainly have a structure that crushes waste foam and then compresses it into blocks. This must obtain environmental assessment qualifications before it can be used in actual production. Due to the difficulty of obtaining qualifications, the application of this kind of equipment has great limitations.

Specific embodiments

[0022] The following further elaborates the present invention in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present invention are described by way of illustration. It is understood that those of ordinary skill in the art can recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the accompanying drawings and the description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0023] As Figures 1 to 8As shown together, a waste foam briquetting machine includes a frame 1, on which a machine box 2 is fixedly arranged. Through holes 31 and 32 are respectively formed in two opposite side walls at the bottom of the machine box 2. An accumulation space 3 is formed between the through hole 31 and the through hole 32. A feed inlet 21 higher than the accumulation space 3 is arranged on the box wall of the machine box 2. Waste foam material 91 is input into the machine box 2 from the accumulation space 3 and forms a natural accumulation at the accumulation space 3.

[0024] A pushing block 4 that is hermetically and slidably matched with the through hole 31 is installed at the through hole 31. Thus, after the pushing block 4 extends into the accumulation space 3, the tightness at the through hole 31 can still be maintained. The pushing block 4 is connected with a pushing driver 41. Initially, the pushing surface of the through hole 31 is coplanar with the inner wall of the machine box 2, that is, it serves as a temporary side wall to jointly enclose the accumulation space 3 with the machine box 2. After a certain amount of material enters, the pushing driver 41 drives the pushing block 4 to move towards the through hole 32 to realize the pushing function.

[0025] Among them, the pushing driver 41 can directly adopt an oil cylinder or a cylinder, etc. Preferably, the length of the pushing block 4 is greater than the distance between the feed inlet 21 and the through hole 32, so that after the front end of the pushing block 4 is pushed into the through hole 32, the plugging at the through hole 31 can still be maintained.

[0026] A briquetting box 5 that covers the outside of the through hole 32 is installed on the frame 1. Of course, the inner cavity of the briquetting box 5 is in communication with the through hole 32. The pushing driver 41 is used to push the front end of the pushing block 4 into the briquetting box 5, and the material 91 can be directly extruded into blocks in the briquetting box 5. Based on this, the through hole 31, the through hole 32, and the briquetting box 5 are all in the shape of a hole channel adapted to the outer shape of the pushing block 4.

[0027] The briquetting box 5 is connected with a block discharging driver 51 for driving the briquetting box 5 to leave the through hole 32. A block retreating mechanism 6 for disengaging the foam block 92 is arranged on the briquetting box 5. After the material 91 is extruded into blocks in the briquetting box 5, the block discharging driver 51 drives the briquetting box 5 to leave the through hole 32, and the block retreating mechanism 6 disengages the foam block 92 from the briquetting box 5 to form an output in a free-falling manner. Among them, the block discharging driver 51 also adopts an oil cylinder or a cylinder, etc.

[0028] The block retreating mechanism 6 in this embodiment includes a block retreating hole 61 penetrating through the side wall of the block forming box 5 away from the block forming opening 32. A block retreating rod 62 is fixedly provided on the frame 1 on the side of the block forming box 5 away from the block forming opening 32, and the block retreating rod 62 extends to the position of the block retreating hole 61. When the block forming box 5 covers outside the block forming opening 32, the block retreating rod 62 blocks the block retreating hole 61 to ensure that the foam is extruded into blocks. When the block forming box 5 leaves the block forming opening 32, the block retreating rod 62 is passively extended into the block retreating hole 61, forming a role of pushing the foam block 92 outwards until the foam block 92 exits the block forming box 5, realizing the falling output.

[0029] A pre-pressing channel 71 is provided above the material accumulation space 3 on the chassis 2. A pre-pressing block 7 is hermetically and slidably installed in the pre-pressing channel 71. The pre-pressing block 7 is used to pre-press the material 91 into the material accumulation space 3. The pre-pressing block 7 is connected with a pre-pressing driver 72, and the feed inlet 21 is located on the side wall of the pre-pressing channel 71. The material 91 input from the feed inlet 21 accumulates above the material accumulation space 3 and in the material accumulation space 3. By adding the pre-pressing block 7, on the one hand, the material 91 above the material accumulation space 3 can also be pre-pressed to the material accumulation space 3, improving the single pre-pressing amount of the pushing block 4. On the other hand, the bottom surface of the descending pre-pressing block 7 can form the top surface of the material accumulation space 3. The pre-pressing block 7 and the bottom of the chassis 2 can jointly enclose a channel shape adapted to the cross-section of the pushing block 4, and the pushing block 4 can perform a more comprehensive push. Among them, the pre-pressing driver 72 is also realized by using an oil cylinder or a cylinder, etc.

[0030] A locking movable seat 73 extending out of the chassis 2 is fixedly provided on the side wall of the pre-pressing block 7 on the side of the block forming opening 32. A locking fixed block 74 protrudes outside the top wall of the block forming box 5. A locking rod 75 for clamping on the side of the locking fixed block 74 away from the block forming opening 32 is fixedly provided on the locking movable seat 73. Through the above structure, after the pre-pressing block 7 descends for pre-pressing, the locking rod 75 is simultaneously locked to the side of the locking fixed block 74 away from the block forming opening 32, forming a rigid lock on the block forming box 5. Thus, the pushing block 4 can form a stronger pushing pressure in the block forming box 5, which is beneficial to the smooth block forming of the material 91.

[0031] Based on the protrusion of the locking movable seat 73 from the chassis 2 and the lifting movement of the preloading block 7, an avoidance opening corresponding to the locking movable seat 73 should be provided on the side wall of the chassis 2. Preferably, a locking reinforcement sleeve 76 that slidably cooperates with the locking rod 75 is fixedly provided on the outer wall surface of the chassis 2. Through the locking reinforcement sleeve 76, on the one hand, the movement of the locking rod 75 is guided to ensure its smooth locking, and on the other hand, radial restriction can be provided for the locking rod 75 after locking, improving the bending resistance of the locking rod 75 and ensuring the locking force.

[0032] As Figure 1 shown, at the initial stage of using this embodiment, the pushing surface of the pushing block 4 is coplanar with the side wall of the chassis 2, the forming block box 5 covers the outside of the forming opening 32, the preloading block 7 remains in the raised state, and the material 91 is input from the feeding port 21 and accumulates in the material accumulation space 3 and above it.

[0033] As Figure 4 shown, the preloading driver 72 drives the preloading block 7 to descend until the bottom surface of the preloading block 7 is coplanar with the upper edges of the pushing opening 31 and the forming opening 32, and the material 91 input into the chassis 2 is all preloaded in the material accumulation space 3; at this time, the locking rod 75 simultaneously locks the forming block box 5. Preferably, at this time, the preloading block 7 blocks the feeding port 21. Accordingly, the height of the preloading block 7 is greater than the distance between the upper edge of the feeding port 21 and the material accumulation space 3.

[0034] As Figure 6 shown, the pushing driver 41 drives the pushing block 4 to push towards the forming opening 32 until the front end of the pushing block 4 is pressed into the forming block box 5. After stabilizing the pressure for 5 to 10 seconds, a dense foam block 92 is formed by extrusion in the forming block box 5. As Figure 7 shown, the preloading driver 72 drives the preloading block 7 to rise, and the locking of the forming block box 5 is released. The material 91 can continue to be input from the feeding port 21. And based on the fact that at this time the pushing opening 31 simultaneously blocks the pushing opening 31 and the forming opening 32, the input material 91 can form a temporary accumulation above the material accumulation space 3 and will not leak out.

[0035] As Figure 8 shown, the block discharging driver 51 drives the forming block box 5 away from the forming opening 32, and the foam block 92 formed by internal extrusion is separated from the forming block box 5 under the action of the block discharging mechanism 6 and forms a falling output. After the forming block box 5 leaves to a distance where the foam block 92 is sufficient to exit the box, the block discharging driver 51 immediately drives the forming block box 5 to return until it is pressed against the outside of the forming opening 32 again.

[0036] The pushing driver 41 drives the pushing block 4 to retreat to the pushing port 31, and the material 91 freely falls into the material accumulation space 3 for accumulation. The pre-pressing driver 72 drives the pre-pressing block 7 to press down, and the above-mentioned pressing block operation is repeated.

[0037] Thus, in this embodiment, the foam briquetting treatment is completely formed by strong pushing and extrusion, without the need for heating or crushing treatment. No harmful gases are generated during the briquetting process. The application is not restricted by environmental assessment qualifications, etc., and the briquetting process is automated, which is conducive to the supporting automated treatment of waste foam.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
