[0002] In the foam block processing process, foam scraps and small foam pieces will inevitably be produced, and the unique large volume and low density characteristics of foam bring great challenges to the recycling work. A large amount of foam occupies the production space, hindering the orderly development of normal production operation. Due to its large volume, the single loading capacity of the transport vehicle is limited, and multiple round trips are required, increasing transportation costs and reducing logistics efficiency.

[0003] The traditional foam processing method has obvious disadvantages. Manual compaction method consumes a lot of manpower and has extremely low efficiency, and it is difficult to meet the large-scale foam recycling demand. Although mechanical extrusion is assisted by mechanical force, due to the lack of fine design, the compression effect is not satisfactory, and the density of the compressed foam is not uniform and the volume is still large, which is not conducive to subsequent storage and collection and cannot meet the requirements of efficient resource recycling.

[0004] In summary, the traditional foam compression equipment has the problems of complex structure, low compression efficiency and inconvenient collection. Therefore, we propose a foam compression and collection device to solve the above problems. INVENTION CONTENTS

[0024] The baffle 7 is connected with the top of the cover plate 32 through a hinge, and the opening and closing action of the baffle 7 can be realized through the limiting mechanism.

[0027] An infrared sensor 84 is arranged on the inner wall of the top end of the second storage bin 83, when the foam reaches the set upper limit value, the foam will block and reflect the infrared light, so that the light received by the receiving end of the infrared sensor 84 increases, the infrared sensor 84 will send a signal, and the centrifugal fan 1 stops running, so that the device is prevented from being blocked or the subsequent compression process is affected due to the continuous entry of the foam, and the stable and efficient operation of the entire device is ensured.

[0029] Working principle:

[0030] The waste foam or foam block generated by the foam block processing is sucked in through the feeding pipe 2 connected with the air inlet of the centrifugal fan 1, the impeller in the centrifugal fan 1 rotates at high speed, not only providing strong suction, but also breaking the foam block with large volume into small pieces which are easier to handle, and the broken foam enters the storage assembly 8 through the elbow pipe 9.

[0031] The foam first enters the second storage bin 83, and as the foam continues to enter, when the second storage bin 83 is filled, the foam will flow down along the connecting hopper 82 and enter the first storage bin 81, and the first storage bin 81 continues to store the foam until it is also filled, and the foam will continue to enter the compression chamber 3, and during the whole feeding and storage process, the infrared sensor 84 located at the top inner wall of the second storage bin 83 monitors the storage amount of the foam in real time, and when the infrared sensor 84 detects that the foam in the second storage bin 83 has reached the set upper limit value, the centrifugal fan 1 stops running, thereby stopping the suction of new foam and avoiding the whole device from being unable to work normally due to too much material.

[0032] When the foam fills the compression chamber 3 and the centrifugal fan 1 stops working, the power device 5 drives the auger 4 in the compression chamber 3 to rotate, and since the baffle 7 at the discharge port 6 is in a closed state, the whole compression chamber 3 forms a relatively closed space, and the auger 4 continuously stirs and extrudes the foam in the compression chamber 3 during the rotation process, gradually compressing the fluffy foam into blocks.

[0033] When the foam is compressed in the compression chamber 3, the baffle 7 at the discharge port 6 is manually opened, and the compressed foam is pushed out of the discharge port 6 under the continuous pushing of the auger 4, completing the whole foam compression and collection process.
