[0030] The following will be combined Figure 1-3 , a crushing system 2 and a rotary pressing device for separating film materials involved in the embodiments of the present application are described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application.

[0031] In the embodiments of the present application, Figure 1 As shown, a crushing system 2 may include: a housing 27 and a groove component, wherein a mounting cavity is provided in the housing 27, and a feed port 28 and a discharge port 29 are provided on the mounting cavity; the feed port 28 is opposite to a gap formed when the grooves 26 of two toothed discs 21 are opposite to each other. The groove component is arranged in the mounting cavity, and the groove component includes two toothed discs 21 arranged opposite to each other, one toothed disc 21 is fixed, and the other toothed disc 21 is connected to an external driving device; the two toothed discs 21 are provided with grooves 26 arranged at intervals along the outer edges of the toothed discs 21 on opposite sides, the depth of the grooves 26 near the outer edges is greater than the depth near the center of the toothed discs 21, the depth of the grooves 26 of a single toothed disc 21 is less than the diameter of the popping bead, the outer edge end of the gap formed when the grooves 26 of the two toothed discs 21 are opposite to each other is greater than the diameter of the popping bead, and the center end of the gap is less than the diameter of the popping bead.

[0032] The crushing system 2 provided in this embodiment features an ingenious structure. The grooves 26 are formed on two opposing toothed discs 21. These grooves 26 are deep near the outer ends of the toothed discs 21 and shallower within. The grooves 26 are only wide enough to accommodate a single blasting bead. Each toothed disc 21 is approximately 2 cm thick, with grooves 26 and protrusions on one side and a smooth surface on the other. The inner hole in the middle allows for connection to a motor.

[0033] One of the two opposing toothed discs 21 is fixed to the housing 27 of the crushing system 2, while the other is connected to an external motor 5 for rotational motion. The grooves 26 of the two toothed discs 21 correspond with each other, and there is a gap between them. This gap can be manually adjusted according to the size of the pellets, so that a single groove 26 cannot enter the pellets. Only when both grooves 26 are aligned can the pellets flow into the gap formed by the two grooves 26, but they cannot flow out of the gap at the bottom.

[0034] When one tooth disc 21 rotates, the popping beads enter the top of the two tooth discs 21 through the feed port 28. Only when the groove 26 parts of the two tooth discs 21 correspond to each other, can the popping beads enter the gap formed by the two grooves 26 at the top of the two tooth discs, and the width of the gap formed by the two grooves 26 limits the popping beads entering the gap to be arranged in a single strip, and the number of popping beads in a single strip can be between a few and a dozen; and the width below the gap makes it impossible for the uncrushed popping beads to pass through, and the two groove parts rotate relative to each other, so that the protrusions of the groove 26 can crush the popping beads, thereby crushing the entire popping beads arranged in a single strip.

[0035] In some embodiments, an inclined transition surface 22 is formed on the opposite side of the toothed disc 21. The inclined transition surface 22 can be a smooth curved surface, so that the beads flow more smoothly. The outer edge thickness of the toothed disc 21 is less than the center thickness of the toothed disc 21. A plurality of first protrusions 25 are provided on the transition surface 22. A plurality of second protrusions 24 are provided between adjacent first protrusions 25. A plurality of third protrusions 23 are provided between adjacent second protrusions 24 and between first protrusions 25 and second protrusions 24. The length of the first protrusion 25 is greater than the length of the second protrusion 24 and greater than the length of the third protrusion 23. Grooves 26 are formed between adjacent first protrusions 25 and third protrusions 23, second protrusions 24 and third protrusions 23, and third protrusions 23 and third protrusions 23. The first protrusions 25, second protrusions 24, and third protrusions 23 are all triangular prisms, and the cross-section of the triangular prism gradually decreases from the outer edge of the toothed disc 21 to the center of the toothed disc 21. The protrusions are arranged in this way to form grooves 26 of different lengths. The vast majority of the explosive beads can be crushed by the third protrusion 23 in the shorter groove 26. A very small number of explosive beads may pass through the short groove 26 but not be crushed due to defects in themselves, and thus get stuck in the smooth part of the inner side of the toothed disc 21 near the inner ring. At this time, the long second protrusion 24 or the third protrusion 23 can still crush it when the toothed disc 21 rotates, thereby ensuring that all the explosive beads entering the crushing system 2 are completely broken.

[0036] In some embodiments, the first protrusions 25 are arranged at equal intervals, the second protrusions 24 between adjacent first protrusions 25 are arranged at equal intervals, and the third protrusions 23 between adjacent second protrusions 24 are arranged at equal intervals. This can further ensure that all explosive beads entering the crushing system 2 are completely broken.

[0037] This embodiment also provides a rotary pressing device for separating film materials, comprising a feed hopper 1, a filter unit 3, a running motor 5, and the crushing system 2. The feed hopper is connected to the feed inlet 28 of the crushing system 2, the output end of the running motor 5 is connected to a toothed disc 21 of the crushing system 2, and the filter unit 3 is disposed below the discharge port 29 of the crushing system 2. A collection unit 4 is also disposed below the filter unit 3.

[0038] The feed hopper 1 is connected to the crushing system 2 via a pipeline. The inner geared disc of the crushing system 2 is directly connected to the operating motor 5, which provides rotational power. The rotational speed can be adjusted as needed. The outer geared disc is fixed to the outer casing 27 of the crushing system 2 and remains stationary. The filter unit 3 is located below the crushing system 2 and separates the rubber membrane and the liquid discharged from the crushing system 2. The filter unit 3 can be a filter screen. The collection unit 4 is located below the filter unit 3 and is directly connected to the filter unit 3 to collect the liquid discharged from the filter unit 3. The collection unit 4 can be a container with an opening, such as a plastic bucket.

[0039] When the device is running, the popping beads collected at the feed hopper 1 flow to the crushing system 2 through the thin pipe at the lower end. At this time, the gear disc 21 connected to the operating motor 5 in the crushing system 2 is in operation. The popping beads enter the upper part of the two gear discs 21 through the thin pipe below the feed hopper 1. Only when the grooves 26 of the two gear discs 21 partially correspond to each other can the popping beads enter the gap formed by the two grooves 26 at the top of the two gear discs 21. The width of the gap formed by the two grooves 26 limits the popping beads entering the gap to be arranged in a single strip. The number of popping beads in a single strip can be between a few and a dozen. The thickness below the gap prevents uncrushed popping beads from passing through. The two gear discs 21 rotate relative to each other, so that the protrusions of the grooves 26 can crush the popping beads, thereby crushing the entire strip of popping beads.

[0040] After being crushed, the beads are separated into rubber and liquid, both of which flow down from the gap between the two toothed discs 21 and enter the filtration unit 3. The liquid flows down to the collection unit 4 at the lower end, where it is recovered.

[0041] Using the above equipment, 1 kg of recovered popping beads is placed in the feed funnel 1. After being pressed by the oil press, 500-600 g of liquid can be recovered. The mass of the rubber film is about 100 g, and the liquid recovery rate is between 55.5% and 66.6%. All the popping beads are crushed, and there is no problem of accumulation of popping beads and inability to crush them all. The oil press runs smoothly, and there is no shutdown caused by accumulation of popping beads. The recovered liquid is clear and has no odor, and is very similar to the raw material.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
