Description

Technical Field

[0001] The invention relates to the technical field of feeding, in particular to a feeding device for producing sponge grinding blocks. Background Art

[0002] Sponge grinding blocks, also known as sponge sand blocks, polishing grinding blocks, resin grinding blocks, abrasive grinding blocks, plastic grinding blocks, etc., are based on sponge and are planted with abrasive sand. During the production process of sponge grinding blocks, the sponge grinding blocks cut into blocks need to be packaged and stored. When they need to be stored at a higher place, a loading device is required to transport the sponge grinding blocks to a higher place for packaging and storage. However, in the existing technology, the height of the loading device is not easy to adjust, and the pressed sponge grinding blocks need to be dried, usually in a constant temperature and humidity dryer. However, some sponge grinding blocks will still have residual moisture, and will also absorb moisture when in contact with relatively humid air during transportation, resulting in the subsequent stacking process. It is easy to promote the growth of bacteria and mold. At this time, the sponge needs to be dried again before packaging the sponge grinding blocks. However, during drying, due to stacking together, it is easy to dry unevenly. For this reason, we propose a loading device for sponge grinding block production. Summary of the Invention

[0014] Compared with the prior art, the advantages and positive effects of the present invention are

[0015] 1. The present invention proposes a feeding device for producing sponge grinding blocks, wherein the rotating roller can drive the conveyor belt on the surface for transmission. According to the height of the feeding, the second motor drives the support rod to rotate, and drives the bidirectional screw to rotate. The bidirectional screw drives the two lifting frames on the surface to move closer or farther away synchronously. At this time, the distance between the two rotating rollers can be adjusted. The first spring is provided to always push the two sliding frames to make the conveyor belt taut, further improving the stability of transportation. At this time, the conveyor belt can push the sponge grinding blocks on the support plate upward, and the conveying height can be adjusted at the same time, which is convenient for transporting the sponge grinding blocks to different heights, thereby improving work efficiency.

[0016] 2. The present invention proposes a feeding device for the production of sponge grinding blocks. By connecting an external hot air flow to the air inlet pipe, when the reciprocating screw rotates, it can drive the sealing plate on the surface to move up and down. When the sealing plate moves up, the external hot air can be extracted. When the sealing plate moves down, the hot air in the positioning cylinder can be pushed into the air outlet pipe. At this time, the hot air flow can dry the sponge grinding block, avoiding the retention of moisture that causes the sponge to be in a humid environment, which promotes the growth of bacteria and mold.

[0017] 3. The present invention proposes a loading device for the production of sponge grinding blocks. After the conveying height is adjusted, the sponge grinding blocks rise with the support plate. When the support plate drives the top sponge grinding blocks to move to the position of the scraper, the scraper pushes down the vertical sponge grinding blocks on the support plate, so that the sponge grinding blocks can be horizontal on the support plate. This can effectively prevent the airflow from blowing down the sponge grinding blocks during the drying process, resulting in uneven heating. In addition, the airflow can pass through the sponge grinding blocks faster, so that the moisture on the surface can be quickly detached, effectively accelerating the drying efficiency.

[0018] 4. The present invention proposes a loading device for the production of sponge grinding blocks. When the horizontally placed sponge grinding block moves to the position of the protective frame, the rotating cylinder rotates, and the sliding plate drives the protective frame close to the sponge grinding block. At this time, the protective frame can push the two sides of the sponge grinding block to approach the center position of the air outlet. At the same time, the sealing plate moves downward. At this time, the hot air flow enters the air supply box along the air outlet pipe and blows to the sponge grinding block through the air outlet, so that the hot air flow can wrap the sponge grinding block over a larger area and heat it evenly. At the same time, the clamping plate can protect the sponge grinding block to avoid the air flow from blowing it away or even dropping it during the drying process, thereby effectively improving the drying efficiency.

[0019] 5. The present invention proposes a loading device for producing sponge grinding blocks, which drives the push block to rotate during the rotation of the rotating rod. When the slope on the push block contacts the clamping rod on the positioning rod, the push frame drives the push block to slide toward the inside of the push frame, and the push block drives the push plate to leave the protrusion. At this time, the torsion spring drives the rotating plate to rotate. When the scraper pushes the sponge grinding block, some sponge grinding blocks at the edge position fall off. At this time, the fallen sponge grinding blocks slide along the connecting pipe into the feed pipe, so that the top of the support plate can transport a single sponge grinding block at a time, which can effectively avoid the sponge grinding blocks from stacking during transportation, resulting in incomplete drying, greatly increasing the contact area between the hot air flow and the sponge grinding block, so that the sponge grinding block can be better dehydrated, avoiding the stacking of multiple sponges, resulting in incomplete drying of some overlapping positions.

At this time, the inclined or vertical sponge grinding block on the support plate 11 can be pushed down, so that the sponge grinding block can be horizontally on the support plate 11, and the rotating rod 20 continues to rotate. When the slope on the pushing block 22 contacts the clamping rod 30 on the positioning rod 28, the pushing frame 21 continues to rotate, and the pushing block 22 slides toward the inside of the pushing frame 21, and the pushing block 22 drives the pushing plate 23 to leave the protrusion 45. At this time, the torsion spring 18 drives the rotating plate 19 to rotate. When the rotating plate 19 rotates to the position of the stop rod 24, it stops. At this time, the scraper 26 is reset. When the scraper 26 pushes the sponge grinding block, some of the sponge grinding blocks at the edge position fall off.

At the same time, the rotating rod 20 drives the reciprocating screw 37 at the top to rotate during the rotation process, and the sealing plate 38 moves downward. At this time, the hot air flow enters the air supply box 41 along the air outlet pipe 39 and blows to the sponge grinding block through the air outlet.

According to the height of the loading, the distance between the two rotating rollers 5 is adjusted, and the second motor 42 drives the support rod 2 to rotate, and drives the bidirectional screw rod 3 to rotate. The bidirectional screw rod 3 drives the two lifting frames 4 on the surface to approach or move away synchronously, and drives the two rotating rollers 5 to approach or move away synchronously. When the two rotating rollers 5 are close, the conveyor belt 10 is relaxed. At this time, the first spring 13 will push the two sliding frames 7 away from each other, so that the conveyor belt 10 is taut. At this time, the conveying height can be adjusted. After adjusting the conveying height, the sponge grinding block is put into the feed pipe 15 and falls along the inclined plate 16 to the surface of the support plate 11. , the conveyor belt 10 drives the support plate 11 to rise intermittently. When the support plate 11 drives the top sponge grinding block to move to the position of the scraper 26, the support plate 11 stops, and the second motor 42 drives the rotating rod 20 to rotate intermittently. At this time, the rotating rod 20 drives the push frame 21 on the surface to rotate, and the push frame 21 drives the push block 22 on the surface to rotate, and the push block 22 drives the push plate 23 to rotate.
