Description

Technical Field

[0001] The invention relates to the technical field of rubber crushing, in particular to crushing equipment for processing rubber elastic bodies. Background Art

[0002] The structural characteristics of thermoplastic elastomers are that they are composed of resin segments and rubber segments with different chemical bonds. The resin segments form physical crosslinking points due to interchain forces, and the rubber segments are highly elastic segments that contribute to elasticity. The physical crosslinking of the plastic segments changes reversibly with changes in temperature, showing the plastic processing characteristics of thermoplastic elastomers. Therefore, thermoplastic elastomers have the physical and mechanical properties of vulcanized rubber and the processing properties of thermoplastic plastics. They are a new type of polymer material between rubber and resin and are often called third-generation rubber.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] For example 1, please refer to Figure 1-Figure 3The present invention provides a technical solution: a pulverizing device for processing rubber elastic bodies, comprising a base plate 1, a working box 2 fixedly connected to the top of the base plate 1, a feed chute 4 opened on the left side of the working box 2, a roller 3 fixedly connected to the left side of the inner wall of the working box 2, a mounting ring 5 fixedly connected to the surface of the feed chute 4, a cover plate 6 slidably connected to the inner wall of the mounting ring 5 via a slider, a rotating rod 11 rotatably connected to the bottom of the inner wall of the roller 3, a crushing ring 12 fixedly connected to the inner wall of the roller 3, and further comprising:

[0031] The pop-up component 7 includes a blanking plate 701 fixedly connected to the bottom of the inner wall of the roller 3, a pop-up block 702 fixedly connected to the top of the blanking plate 701, a compression pad 703 fixedly connected to the inner wall of the pop-up block 702, and two pop-up blocks 702 are symmetrically installed on the top of the blanking plate 701 with the center line of the blanking plate 701 as the symmetry axis. The bottom of the inner wall of the blanking plate 701 is fixedly connected to a mounting plate 704. The pop-up component 7 also includes a telescopic plate 705. The telescopic plate 705 is fixedly connected to the bottom of the inner wall of the mounting plate 704, the top of the telescopic plate 705 is fixedly connected to a compression ring 706, the top of the mounting plate 704 is fixedly connected to a telescopic pad 707, the bottom of the telescopic pad 707 is in contact with the top surface of the compression ring 706, the top of the telescopic pad 707 is fixedly connected to an air pressure pad 709, the top of the telescopic pad 707 is slidably connected to an ejection wheel 708, the ejection wheel 708 is in contact with the bottom surface of the air pressure pad 709, and the cover plate 6 is pulled downward from the inner wall of the mounting ring 5 to leak out. The feeding groove 4 on the surface of the box 2 feeds the rubber elastic body into the inside of the drum 3 from the feeding groove 4. A part of the elastic body falls to the blanking plate 701 at the bottom of the drum 3, and the elastic body falls to the surface of the pop-up block 702 to impact it. When impacting the pop-up block 702, the compression pad 703 inside it is squeezed. After being squeezed, the compression pad 703 bends inward and then releases pressure outward due to its own elasticity, causing the elastic body to pop up into the inside of the drum 3. The other part of the elastic body falls to the surface of the air pressure pad 709 and hits the expansion pad 703. 07 is squeezed, and the bottom of the telescopic pad 707 comes into contact with the compression ring 706 after being squeezed. By squeezing the compression ring 706, it is bent inward and generates an air pressure inside the telescopic plate 705, and then the air pressure enters the compression ring 706 upward. After the compression ring 706 is injected with air pressure, it expands outward one by one, driving the ejection wheel 708 to slide on the top of the telescopic pad 707. The ejection wheel 708 rolls on the bottom of the air pressure pad 709 to eject the elastomer from the surface of the air pressure pad 709 upward to the surface of the rotating rod 11.

[0032] Example 2: The difference from Example 1: Figure 4, the crushing component 8 includes a plug-in plate 801 fixedly connected to the surface of the rotating rod 11, and a corner block 808 is fixedly connected to the surface of the plug-in plate 801. The inner wall of the plug-in plate 801 is rotatably connected to the rotating disk 802 through the rotating rod, and the bottom of the inner wall of the rotating disk 802 is fixedly connected to the cutting block 803. The surface of the rotating rod 11 is provided with a crushing component 9, and the end of the rotating rod 11 away from the feed chute 4 is provided with a clamping component 10. The crushing component 8 also includes a telescopic block 804, which is fixedly connected to both sides of the plug-in plate 801, and the end of the telescopic block 804 away from the plug-in plate 801 is fixedly connected to the fixed plate 805, and the end of the fixed plate 805 away from the telescopic block 804 is fixedly connected to the powder The crushing plate 806 is fixedly connected to the top of the crushing plate 806 with a crushing claw 807. The power device is started to drive the rotating rod 11 to rotate, and the plug-in plate 801 on the surface rotates along with it. When the plug-in plate 801 rotates, the surface of the rubber body can be cut through the corner blocks 808 on its surface. When the plug-in plate 801 rotates, the rotating plate 802 rotates on the inner wall of the plug-in plate 801 due to inertia, and the surface of the elastomer is cut through the cutting blocks 803 on the surface. At the same time, when the plug-in plate 801 rotates, the telescopic block 804 will move back and forth with it, and drive the crushing claws 807 on the surface of the crushing plate 806 to move left and right, and finally the rubber elastomer is cut through the moving crushing claws 807.

[0033] Example 3: The difference from Example 1: Figure 5-Figure 6The crushing component 10 includes a mounting block 101, which is fixedly connected to the inner wall of the drum 3.

The left and right sides of the impact rod 104 are fixedly connected to a bent plate 103, and the end of the bent plate 103 away from the impact rod 104 is fixedly connected to a pressure ring 105. The two sides of the impact rod 104 are fixedly connected to an impact pad 106, and the inner wall of the impact pad 106 is fixed to the pressure ring 105. The surface of the ring 105 is fixedly connected, and the crushing component 10 also includes a clamping plate 107, which is fixedly connected to one end of the rotating rod 11, and a crushing block 108 is fixedly connected to the bottom of the inner wall of the clamping plate 107.

The clamping plate 110 is fixedly connected to the top plate 111 on the top of the top plate 111. The elastic block 112 is fixedly connected to the elastic block 112. When the impact pad 113 is hit, the elastic block 112 is retracted inwards to buffer the impact force, thereby preventing the top plate 111 from falling off the surface of the movable ring 109. After the impact, the impact pad 106 will cause the bent plate 103 to bend inwards, and after the impact rod 104 is hit, the compression block 102 at the top will also be compressed upwards to buffer the impact force. After the impact pad 113 is hit, the elastic block 112 bends outwards to squeeze the clamping plate 110 at the bottom. After being squeezed, the clamping plate 110 moves downwards through the movable ring 109 to the surface of the crushing block 108, and finally the crushed rubber sheet is crushed by the mutual engagement of the cut pieces on the surface of the crushing block 108 and the clamping plate 110.

[0034] Example 4: The difference from Example 1: Figure 7The crushing component 9 includes a crushing ring 901, which is fixedly connected to the surface of the rotating rod 11.

The two limiting plates 902 are symmetrically installed on the top of the crushing ring 901 with the center line of the crushing ring 901 as the symmetry axis. The left side of the limiting plate 902 is in contact with the surface of the rotating rod 11. A feeding hole 904 is provided on the top of the crushing ring 901, and a discharge trough 903 is provided on the surface of the crushing ring 901. The crushing component 9 also includes a grinding block 905, which is fixedly connected to the inner wall of the crushing ring 901. The inner wall of the grinding block 905 rotates A shark tooth plate 906 is connected, and an extrusion block 907 is fixedly connected to the surface of the discharge trough 903. The cut rubber elastomer flows into the feed hole 904 through the space connected by the two limiting plates 902. After entering the crushing ring 901, the elastomer is chopped up inside the crushing ring 901 by the grinding block 905 and the shark tooth plate 906, and the shark tooth plate 906 that continuously swings left and right on the inner wall of the grinding block 905 pushes the elastomer out of the discharge trough 903. When the elastomer flows out to the inner wall of the drum 3, the extrusion block 907 and the crushing ring 12 contact and squeeze the elastomer to crush it, which can prevent the elastomer from being ejected from the surface of the cutting tool during cutting.
