[0001] The invention relates to the technical field of rubber products, in particular to a hot-melt crushing and recovery device for rubber products. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation and is highly flexible at room temperature. Rubber is a completely amorphous polymer with a high molecular weight, often exceeding hundreds of thousands. Early rubber was derived from latex from plants such as rubber trees and rubber grass.

To save costs, this waste is crushed and recycled.

[0003] However, in the prior art, after the rubber is hot-melted into liquid, it often partially cools and produces residue in the drainage pipe. Long-term use will cause drainage blockage and reduce drainage efficiency. In addition, the broken rubber will be accompanied by gas, so bubbles will appear in the hot-melt liquid, thereby reducing the quality of the subsequent molded rubber. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0028] Please refer to Figure 1 - Figure 6 An embodiment of the present invention provides a technical solution: a hot-melt crushing and recycling device for rubber products, including an upper box body 1 and a crushing component 2 arranged in the upper part of the inner cavity of the upper box body 1. The lower end of the upper box body 1 is communicated with a lower box body 3. A heating box 4 is provided on the outer wall of the bottom end of the lower box body 3. A connecting plate 5 is fixedly connected to the outer wall of the bottom end of the lower box body 3. A liquid distribution pipe 6 is communicated with the outer wall of the bottom end of the lower box body 3. A stand 7 is provided on one side of the liquid distribution pipe 6. An electric push rod 8 is arranged on the stand 7. A piston 91 is fixedly connected to the extending end of the electric push rod 8. A baffle 11 is rotatably arranged in the upper inner cavity of the lower box body 3. It further includes:

[0029] A slag discharging mechanism 9, which can effectively clean the residues on the inner wall of the pipe. The slag discharging mechanism 9 is arranged in the liquid distribution pipe 6;

[0030] And a defoaming mechanism 10, which can quickly remove the bubbles in the liquid. The defoaming mechanism 10 is arranged in the connecting plate 5.

[0031] The baffle 11 can only rotate upward. The central axis of the baffle 11 is connected with a turntable.

[0032] When heating the rubber, the liquid level is located below the upper port of the connecting pipe 96.

[0033] Specifically, when the piston 91 is inserted into the liquid distribution pipe 6, the outer wall of the slag discharging mechanism 9 can scrape the residues on the inner wall of the liquid distribution pipe 6 and push the residues to the lower inner cavity of the lower box body 3, preventing the residues from accumulating due to long-term non-cleaning, which is convenient and fast. When the piston 91 is pulled out, the gas in the lower box body 3 can be pumped out. The air pressure in the inner cavity of the lower box body 3 decreases, which can cause a pressure difference inside and outside the bubbles, thereby accelerating the rupture of the bubbles, improving the quality of the rubber. And when the piston 91 is pulled out and the piston 91 is not separated from the liquid distribution pipe 6, due to the suction force generated by the pressure difference, the adhered residues on the outer wall of the end of the piston 91 close to the lower box body 3 can be removed, so that the piston 91 can achieve the self-cleaning function, which is convenient and low-cost.

[0034] In another embodiment provided by the present invention, the slag discharging mechanism 9 includes a piston 91. One end of the piston 91 far from the electric push rod 8 is movably inserted into the inner cavity of the liquid distribution pipe 6. An insertion block 92 is fixedly connected to the outer wall of the piston 91. A rotating block 93 is sleeved on the outside of the upper end of the insertion block 92 up and down. A rotating plate 94 is rotatably arranged on the outer wall of the rotating block 93. A connecting frame 95 is rotatably arranged on the outer wall of the rotating plate 94. The connecting frame 95 is fixedly connected to the outer wall of the lower box body 3. A connecting pipe 96 is communicated between the liquid distribution pipe 6 and the upper inner cavity of the lower box body 3.

[0035] The outer wall of the piston 91 is in close contact with the inner wall of the liquid distribution pipe 6.

[0036] Specifically, when the piston 91 is inserted into the liquid distribution pipe 6, the outer wall of the slag discharging mechanism 9 can scrape the residues on the inner wall of the liquid distribution pipe 6 and push the residues into the lower inner cavity of the lower box body 3, preventing the residues from accumulating due to long-term non-cleaning, which is convenient and fast.

[0037] In another embodiment provided by the present invention, the defoaming mechanism 10 includes a lifting plate 101. The lifting plate 101 is vertically movably inserted into the lower box body 3. The upper part of the lifting plate 101 is respectively provided with a second notch 1011 and a first notch 1010. The upper end of the rotating plate 94 is movably inserted with a second insert block 102. A sliding rod 103 is movably sleeved outside the central axis of the second insert block 102. The sliding rod 103 is horizontally slidably arranged in the connecting plate 5. A rack 104 is vertically movably inserted on the lower surface of one end of the sliding rod 103 close to the lower box body 3. The upper end of the rack 104 is meshed with an external tooth 107. The inner side of the external tooth 107 is fixedly connected with a rotating shaft 105. The rotating shaft 105 is rotatably arranged in the connecting plate 5. Two magnetic blocks 108 are arranged on the upper side of the sliding rod 103. A pull rope 106 is wound around the outer wall of the rotating shaft 105. The other end of the pull rope 106 is connected with the lifting plate 101. A spring 109 is fixedly connected between the upper end of the lifting plate 101 and the lower box body 3.

[0038] The two magnetic blocks 108 have opposite magnetic polarities.

[0039] A torsion spring is fixedly connected between the outer wall of one end of the rotating shaft 105 and the connecting plate 5.

[0040] Specifically, when the piston 91 is withdrawn, the gas in the lower box body 3 can be withdrawn, and the air pressure in the inner cavity of the lower box body 3 decreases, which can cause a pressure difference inside and outside the bubbles, thereby accelerating the rupture of the bubbles, improving the quality of the rubber. And when the piston 91 is withdrawn and the piston 91 is not separated from the liquid distribution pipe 6, due to the suction force generated by the pressure difference, the adhered residues on the outer wall of one end of the piston 91 close to the lower box body 3 can be removed, so that the piston 91 can achieve the function of self-cleaning, which is convenient and low-cost.

[0041] Working principle: When in use, first open the baffle 11 through the turntable, then start the electric push rod 8, and the piston 91 will be inserted into the inner cavity of the liquid distribution pipe 6. Then, the outer wall of the slag discharging mechanism 9 can scrape the residues on the inner wall of the liquid distribution pipe 6 and push the residues into the lower inner cavity of the lower box body 3, preventing the residues from accumulating due to long-term non-cleaning, which is convenient and fast. After that, the rubber is put in from the upper side of the upper box body 1. After the rubber is crushed, it will fall into the lower inner cavity of the lower box body 3. Then, open the heating box 4 to heat and melt the rubber fragments to turn the rubber into a liquid. The liquid level is lower than the upper port of the connecting pipe 96, which is convenient for subsequent defoaming.

[0042] Afterwards, the baffle 11 is lowered to the horizontal state by the turntable. After the rubber is completely melted, the electric push rod 8 is started to withdraw the piston 91 from the inner cavity of the liquid distribution pipe 6. One end of the rack 104 away from the lower box body 3 has magnetism. At this time, due to the repulsion of the magnetic block 108 on the rack 104, the rack 104 is located at the lower side at this time, and the rack 104 is not engaged with the external teeth 107. Furthermore, under the elastic force of the spring 109, the lifting plate 101 will move downward, and the connecting pipe 96 communicates with the inner cavity of the lower box body 3, and the liquid distribution pipe 6 no longer communicates with the inner cavity of the lower box body 3. Therefore, when the piston 91 is withdrawn, the gas in the lower box body 3 can be withdrawn. The air pressure in the inner cavity of the lower box body 3 is reduced, which can generate a pressure difference inside and outside the bubbles, thereby accelerating the rupture of the bubbles and improving the quality of the rubber. When the rack 104 is reset, another magnetic block 108 will suck the rack 104 upward, so that the rack 104 is located at the upper side again;

[0043] When the piston 91 is withdrawn and the piston 91 is not separated from the liquid distribution pipe 6, due to the suction force generated by the pressure difference, the adhesion residue on the outer wall of one end of the piston 91 close to the lower box body 3 can be removed. Thus, the piston 91 can achieve the function of self-cleaning, which is convenient and low-cost. After the piston 91 is withdrawn from the liquid distribution pipe 6, the liquid in the lower box body 3 can be discharged from the liquid distribution pipe 6.

[0044] 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 descriptions in the above embodiments and 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. The scope of the present invention claimed is defined by the appended claims and their equivalents.
