Description

Technical Field

[0001] The invention relates to the technical field of hot pressing devices, in particular to a hot pressing device for recycling industrial waste plastics. Background Art

[0002] With the continuous development of the plastic manufacturing industry, plastic products are used in a wide range of applications. In the industrial field, industrial plastics are converted into industrial waste plastics after a certain number of years of use. Nowadays, hot pressing devices are generally used to recycle industrial waste plastics.

[0003] At present, the main problem of most hot pressing devices for recycling industrial waste plastics on the market is that when industrial waste plastics are put into the hot pressing device, the crushing device can only perform a single meshing crushing on the plastic, which makes the crushing efficiency low, and the plastic feeding time is long, so that the input of plastic needs to be controlled at intervals. In addition, when the heating device heats the plastic, the gas generated by the heating of the plastic will overflow outward from the feed port, thereby polluting the environment. In addition, general extrusion devices mainly extrude through a flat plate. Since the flat plate is in contact with the extruded object by a plane, the required extrusion force is large, thereby consuming more energy. After the hot pressing of the plastic, the heated plastic is easy to adhere to the extrusion block, making the plastic difficult to separate. The above situation will result in only a single meshing crushing, low crushing efficiency, a long time for plastic feeding, the need for interval control, gas overflowing outward from the feed port, polluting the environment, requiring a large extrusion force, consuming more energy and the problem of difficulty in separating the plastic.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a hot pressing device for recycling industrial waste plastics, which has the following beneficial effects:

[0019] 1. The hot pressing device for recycling industrial waste plastics puts the industrial waste plastics to be hot pressed into the feed hopper, and at the same time starts the motor to drive the rotating shaft to rotate, so that the rotating shaft drives the crushing roller fixedly connected to it to rotate synchronously while rotating. Since the inner side wall of the vertical part of the feed hopper is provided with a long groove, the crushing roller cooperates with the long groove while rotating to efficiently crush the plastic located at the crushing roller. This structure achieves the effect of efficient crushing.

[0020] 2. The hot pressing device for recycling industrial waste plastics drives the circular ring block fixedly connected to it to rotate synchronously while the rotating shaft rotates, so that the circular ring block drives the outer connecting plate to rotate. Since the right side of the connecting plate is provided with a connecting block and a crushing wheel, the crushing wheel rolls in contact with the plastic while it rotates, thereby initially crushing the plastic. Since the connecting plate is inclined, the initially crushed plastic can be quickly transported downward while it rotates. This structure achieves the purpose of multi-directional crushing, shortening the time for plastic feeding, and high crushing efficiency.

[0021] 3. The hot pressing device for recycling industrial waste plastics, after the plastic is crushed, a notch is provided on the partition plate, so that the plastic flows into the lower part of the casing, and then the plastic is heated by an external heating device. After heating for a period of time, the telescopic rod is started to drive the extrusion block to extrude the plastic inward. Since the extrusion block is provided with evenly distributed stepped grooves, it can be extruded on multiple planes, so that the required extrusion force is small. This structure achieves the effect of small required extrusion force and energy saving.

[0022] 4. The hot pressing device for recycling industrial waste plastics rotates through the rotating shaft and drives the partition plate fixedly connected to it to rotate synchronously. Since the partition plate is located on the lower side of the feed hopper, it can isolate most of the heated gas from overflowing. Since the partition plate is arc-shaped, the plastic will not be affected when it falls. At the same time, when the partition plate drives the inclined plate to rotate synchronously, a downward airflow will be generated, making it more difficult for the heated gas to overflow. This structure can isolate the heated gas and prevent environmental pollution.

[0023] 5. In the hot pressing device for recycling industrial waste plastics, when the extrusion block extrude the plastic, the computer system controls the moving cylinder to compress the second spring. When the extrusion block is reset after the extrusion is completed, the protrusion passes over the limiting block through the spring force of the third spring, so that the separation rod moves inward rapidly under the action of the second spring and the third spring, and then the separation rod separates the plastic from the stepped groove. This structure achieves the effect of ejecting and quickly separating the plastic.

[0024] 6. The hot pressing device for recycling industrial waste plastics is provided with notches, semicircular blocks and through holes on the partition plate, so that during the process of extruding the plastic, the internal gas can be discharged to the outside through the through holes, resulting in fewer pores inside the compressed plastic.

[0048] The specific usage and function of this embodiment are as follows:

[0049] When in use, the staff first puts the industrial waste plastics to be hot-pressed into the feed hopper 21, and at the same time starts the motor 41 to drive the rotating shaft 42 to rotate, so that the rotating shaft 42 drives the crushing roller 43 fixedly connected to it to rotate synchronously while rotating. Since the inner side wall of the vertical part of the feed hopper 21 is provided with a long groove 22, the crushing roller 43 cooperates with the long groove 22 while rotating to efficiently crush the plastic located at the crushing roller 43. This structure achieves the effect of efficient crushing.

[0050] Furthermore, while the rotating shaft 42 is rotating, the annular block 51 fixedly connected thereto is driven to rotate synchronously, so that the annular block 51 drives the outer connecting plate 52 to rotate. Since the right side of the connecting plate 52 is provided with a connecting block 53 and a crushing wheel 54, the crushing wheel 54 rolls in contact with the plastic while it is rotating, thereby performing preliminary crushing of the plastic. Moreover, since the connecting plate 52 is inclined, the preliminary crushed plastic can be quickly transported downward while it is rotating. This structure achieves the purpose of multi-directional crushing, shortening the time for plastic feeding, and high crushing efficiency.

[0051] Furthermore, after the plastic is crushed, due to the notch on the partition plate 61, the plastic flows into the lower part of the casing 1, and then is heated by an external heating device. After a period of heating, the telescopic rod 71 is started to drive the extrusion block 72 to extrude the plastic inward. Since the extrusion block 72 is provided with evenly distributed stepped grooves 73, it can be extruded on multiple planes, so that the required extrusion force is smaller. This structure achieves the effect of smaller required extrusion force and energy saving.

[0052] Furthermore, when the rotating shaft 42 rotates, the partition plate 44 fixedly connected thereto is driven to rotate synchronously. Since the partition plate 44 is located on the lower side of the feed hopper 21, it can isolate most of the heated gas from escaping outward. Since the partition plate 44 is arc-shaped, the plastic will not be affected when it falls. At the same time, when the partition plate 44 drives the inclined plate 45 to rotate synchronously, a downward airflow will be generated, making it more difficult for the heated gas to overflow. This structure can isolate the heated gas and prevent environmental pollution.

[0053] Furthermore, when the extrusion block 72 extrude the plastic, the computer system controls the moving cylinder 88 to compress the second spring 87. When the extrusion block 72 is reset after the extrusion is completed, the protrusion 85 passes over the limiting block 83 through the spring force of the third spring 89, so that the separation rod 86 moves inward rapidly under the action of the second spring 87 and the third spring 89, and then the separation rod 86 separates the plastic from the stepped groove 73. This structure achieves the effect of ejecting and quickly separating the plastic.

[0054] Furthermore, since the partition plate 61 is provided with a notch, a semicircular block 62 and a through hole 63, during the process of extruding the plastic, the internal gas can be discharged outward through the through hole 63, resulting in fewer pores inside the compressed plastic. This structure achieves the purpose of a good extrusion effect.
