Description

Technical Field

[0001] The invention belongs to the field of silica gel recovery, in particular to a silica gel product scrap recovery device. Background Art

[0002] In the field of silicone product recycling technology, the existing process usually adopts the path of "physical crushing - fragment collection - subsequent processing". Specifically, the waste silicone products are first sent to the crushing device and broken into granular or flaky fragments under mechanical action. Subsequently, these fragments are concentrated through the collection system so that they can be transferred to the subsequent recycling processing link.

[0003] A patent document with publication number CN222270923U discloses a silica gel crushing material collection device, including a crushing box, a feed hopper, a discharge box and a material control mechanism. A base is provided directly below the discharge box, and a bracket is fixedly installed between the side of the crushing box and the base, which can enable the two collection boxes to rotate. After the collection box located below the discharge box is filled with silica gel, the other empty collection box can be rotated to the bottom of the discharge box to continue collecting silica gel.

[0004] In the recycling process of silicone waste, the crushed silicone scraps must first be collected and transferred to the downstream regeneration unit. However, due to the inherent high elasticity, surface self-adhesion and irregular geometric characteristics of silicone materials, the scraps generally connect with each other during the unloading and collection process, forming clusters or bridge arches, causing discharge blockage. The high elasticity of the scraps causes the scraps to rebound under the action of gravity, further exacerbating the bridging. In addition, the scraps accumulate instantly when unloading in batches, forming a non-uniform material layer on the conveyor belt surface, affecting the continuity and stability of subsequent homogenization, metering and mechanical regeneration.

[0018] 1. The silicone product scrap recovery device described in the present invention is characterized in that the silicone scraps continue to fall through the inclined rubber belt to the closest distance between the two rubber belts. When the silicone scraps are discharged through the closest distance between the two rubber belts, they are discharged in a surface shape, so that the silicone scraps can be evenly spread on the recovery conveyor belt. A displacement ring is movably installed at the middle position of the rotating movable shaft.

The electric telescopic column is extended and retracted to drive the lifting shaft to move up and down, thereby changing the horizontal height of the lifting shaft. Because the rubber belt needs to be tightened at all times to enable the rubber belt to be transmitted, when the movable rotating shaft moves laterally and causes the rubber belt to relax, the lifting component can drive the lifting shaft to descend, straighten the rubber belt again, and restore its transmission state. Through this action, the distance between the two movable rotating shafts, that is, the minimum distance between the two rubber belts, can be adjusted to match different silicone scraps, further improving the collection and recovery rate of silicone scraps.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1: Figures 1-6 As shown, a silicone product scrap recycling device according to an embodiment of the present invention includes a scrap bin 1 and a uniform material recovery bin 2 installed below the scrap bin 1. The uniform material recovery bin 2 is installed below the scrap bin 1, and a bottom bracket 3 is installed below the uniform material recovery bin 2. A recycling conveyor belt 4 is movably installed on the inner bottom of the bottom bracket 3, and a blowing member 5 is fixedly installed on one side of the top of the bottom bracket 3.

[0033] Two corresponding material distribution components 6 are movably installed inside the material distribution box 2. The material distribution component 6 includes a top shaft 61 movably installed on the top of the material distribution box 2 and a lifting shaft 62 movably installed on the top of the material distribution box 2. Lifting components 65 are installed at both ends of the lifting shaft 62. The lifting component 65 is installed on the bottom outer side of the material distribution box 2. The material distribution component 6 also includes a movable rotating shaft 63 movably and rotatably installed in the middle section of the material distribution box 2. The connecting structure at the end of the movable rotating shaft 63 drives the movable rotating shaft 63 to rotate. The outer sides of the top shaft 61, the lifting shaft 62 and the movable rotating shaft 63 are tensioned with a rubber belt 64. A reciprocating displacement ring 7 is installed on the outer side of the movable rotating shaft 63. The displacement ring 7 is in contact with the rubber belt 64.

[0034] Specifically, the silicone product is placed inside the crushing box 1 for crushing to form crushed materials, and then the silicone crushed materials will fall into the inside of the uniform material recovery box 2, and the movable rotating shaft 63 pushes the two corresponding rubber belts 64 to form a gap. A downward inclined frame is installed above the uniform material recovery box 2, and the silicone crushed materials will fall to the position between the two rubber belts 64. At this time, the rubber belt 64 above the movable rotating shaft 63 is in an inclined state. The silicone crushed materials will first contact the top of the rubber belt 64 when they are discharged from the upper part of the uniform material recovery box 2, and continue to fall to the two rubber belts 64 through the inclined rubber belt 64. At the closest distance between the two rubber belts 64, when the silicone scraps are discharged through the closest distance between the two rubber belts 64, they will be discharged in a surface shape, so that the silicone scraps can be evenly spread on the recycling conveyor belt 4, thereby not easily stacked, and also avoid the situation where the elastic recovery after stacking due to the high elasticity of silicone is aggravated by the bridge. In addition, under the power drive, the movable shaft 63 can rotate, and at this time the rubber belt 64 is tightened by the top shaft 61 and the lifting shaft 62, so the rubber belt 64 is driven to perform transmission work, and the continuously transmitted rubber belt 64 will pull the falling silicone The scraps are transported more quickly to the position closest to the distance between the two rubber belts 64, and the situation that the silicone scraps stick to the outer surface of the rubber belt 64 is avoided. A displacement ring 7 is movably installed in the middle position of the rotating movable shaft 63. The displacement ring 7 can move outside the circumference of the movable shaft 63, and the displacement ring 7 contacts the inner side of the rubber belt 64 at the corresponding position, thereby pushing the rubber belt 64 part on one side of the movable shaft 63 to deform, that is, the part of the rubber belt 64 corresponding to the middle of the movable shaft 63 will continuously deform and return The local curvature and tension of the rubber belt 64 can be changed periodically, so that the silicone crumbs are passively disturbed, dispersed and fluidized during the falling process, further avoiding the problem of the crumbs being connected with each other, forming clusters or bridge arches, and causing discharge blockage. When the silicone crumbs are evenly laid out in a surface state through the two material-distributing components 6, the lighter plastics and impurities in the silicone crumbs are blown out and collected separately through the lateral air outlet effect of the blowing component 5, and the remaining silicone crumbs are spread on the recovery conveyor belt 4 for collection and recycling, so as to facilitate the subsequent regeneration processing link.

[0035] like Figure 3-Figure 5 As shown, the lifting component 65 includes a support plate 651 installed on the outside of the end of the lifting shaft 62. The end of the lifting shaft 62 is rotatably connected to the support plate 651 through an axis. An electric telescopic column 652 is fixedly installed below the support plate 651. The electric telescopic column 652 is fixedly installed inside the uniform material recovery box 2.

[0036] The bottom of the evenly distributed material recovery box 2 is penetrated by a plurality of through slots 21 , and the shaft for connecting the lifting shaft 62 and the support plate 651 is located inside the through slots 21 . The bottom of the evenly distributed material recovery box 2 is also penetrated by a plurality of moving slots 22 .

[0037] An adjusting motor 24 is installed on one side of the movable groove 22, and a movable plate 23 is installed at the bottom of the adjusting motor 24. The movable plate 23 is fixedly installed on the outside of the uniform material recovery box 2, and a sliding block 231 is slidably installed inside the movable plate 23. The sliding block 231 is fixedly connected to the lower side of the adjusting motor 24, and the output shaft at the end of the adjusting motor 24 is connected to the movable rotating shaft 63.

[0038] Specifically, different silicone products have different shapes after being crushed by the crushing box 1, and the spacing required for the crushed materials to be evenly laid out also varies. In this device, the sliding block 231 can be moved inside the movable plate 23 to drive the adjustment motor 24 to move. At this time, the movable shaft 63 located between the two corresponding adjustment motors 24 will be displaced horizontally. The two corresponding adjustment motors 24 can be set as a balance block, thereby reducing the number of motors. While the movable shaft 63 moves horizontally, the electric telescopic column 652 is extended and retracted to drive the lifting shaft 62 to move up and down, changing the horizontal height of the lifting shaft 62. Because the rubber belt 64 needs to be tightened at all times to enable the rubber belt 64 to be transmitted, when the movable shaft 63 moves horizontally and causes the rubber belt 64 to relax, the lifting member 65 can drive the lifting shaft 62 to descend, re-stretch the rubber belt 64, and restore its transmission state. Through the above action, the spacing between the two movable shafts 63, that is, the minimum spacing between the two rubber belts 64, can be adjusted to match different silicone crushed materials, further improving the collection and recovery rate of silicone crushed materials.

[0039] like Figure 2 As shown, the blowing component 5 includes a fixed fan 51 fixedly installed on the outside of the bottom bracket 3 and an air duct 52 fixedly installed on the end of the fixed fan 51. A trapezoidal tube 53 is fixedly installed at one end of the air duct 52, and the trapezoidal tube 53 is used to blow strip-shaped air to the unloaded materials inside the uniform material recovery box 2.

[0040] Specifically, in this device, the silicone crumbs are evenly distributed in a surface state after passing through the two material-distributing components 6. At this time, the fixed fan 51 is driven, so that the wind enters the interior of the trapezoidal tube 53 through the air duct 52, and then blows the evenly distributed silicone crumbs in a strip shape, blowing out the lighter plastics and impurities in the silicone crumbs at this time, and collecting them for subsequent recycling or regeneration process.

[0041] like Figure 6-Figure 7As shown, two displacement adjustment parts 26 are movably installed inside the material distribution box 2. The displacement adjustment parts 26 are located inside the rubber belt 64. The displacement adjustment parts 26 include a fixed motor 261 fixedly installed on the outside of the material distribution box 2 and a screw rod 262 rotatably installed inside the material distribution box 2. The output end of the fixed motor 261 is connected to the screw rod 262. The outer side of the screw rod 262 is spirally connected to a moving ring 263. A telescopic rod 265 is installed on the outer side of the moving ring 263. The moving ring 263 is connected to the displacement ring 7 through the telescopic rod 265. The displacement adjustment part 26 also includes two guide rods 264 fixedly installed inside the material distribution box 2. The guide rod 264 passes through the moving ring 263 to guide the movement of the moving ring 263.

[0042] The movable rotating shaft 63 includes end shafts 631 rotatably mounted on both sides of the material recovery box 2 and a central shaft 632 fixedly mounted between the two end shafts 631 , and the displacement ring 7 is reciprocatingly mounted on the outside of the central shaft 632 .

[0043] A plurality of balls 71 are movably mounted inside the hollow interior of the displacement ring 7 , and the plurality of balls 71 are in contact with the outer side of the central shaft 632 . The interior of the displacement ring 7 is hollow, and a groove is provided on the side of the displacement ring 7 closest to the rubber belt 64 .

[0044] Two air supply components 25 are fixedly installed on the inner wall of the uniform material recovery box 2. The air supply component 25 includes an air pump 251 and a telescopic air pipe 252 fixedly installed at one end of the air pump 251. One end of the telescopic air pipe 252 is connected to the hollow part inside the displacement ring 7.

[0045] Specifically, as the adjusting motor 24 is driven, the movable rotating shaft 63 rotates as a whole, thereby driving the rubber belt 64 to transmit. At this time, the displacement ring 7 is installed on the outside of the rotating central shaft 632, and the screw rod 262 is driven to rotate by the forward and reverse rotation of the fixed motor 261. Due to the guiding effect of the fixed guide rod 264, the movable ring 263 will reciprocate on the outside of the screw rod 262, that is, it drives the displacement ring 7 connected to the telescopic rod 265 to reciprocate on the outside of the central shaft 632. Due to the arrangement of multiple balls 71 and the telescopic rod 265, the displacement ring 7 does not rotate with the central shaft 632. The reciprocating movement of the displacement ring 7 will cause the part of the rubber belt 64 in contact with its outer side to deform, periodically changing the rubber belt 64. The local curvature and tension of the displacement ring 7 are used to passively disturb, disperse, and fluidize the silicone crumbs during the falling process, thereby further avoiding the mutual connection between the crumbs. However, in this process, the outer side of the displacement ring 7 will always be in hard friction with the inner side of the rubber belt 64, thereby affecting the service life of the rubber belt 64. Therefore, in this device, by providing an air supply component 25, the air pump 251 can be driven to input gas into the hollow interior of the displacement ring 7 through the telescopic air pipe 252. The gas impacts the inner side of the rubber belt 64 that was originally in contact with the outer side of the displacement ring 7, thereby impacting the rubber belt 64 and deforming it. Compared with traditional hard friction, this device is equivalent to forming an air lubrication between the contact position of the displacement ring 7 and the rubber belt 64, thereby effectively reducing the damage to the rubber belt 64.

[0046] Example 2: Figure 8 As shown, compared with Example 1, another embodiment of the present invention is as follows: a semi-annular groove 1 73 and a semi-annular groove 2 74 are provided inside the displacement ring 7, the semi-annular groove 2 74 is connected to the semi-annular groove 1 73, the thickness of the semi-annular groove 2 74 is greater than the thickness of the semi-annular groove 1 73, a ventilation groove 72 is provided at the bottom of the displacement ring 7, the telescopic air tube 252 is connected to the ventilation groove 72, the ventilation groove 72 is connected to the semi-annular groove 1 73, and a plurality of arc-shaped air grooves 75 are provided on the side of the semi-annular groove 2 74 facing the position closest to the rubber belt 64.

[0047] Specifically, the drive of the air pump 251 allows the gas to be transported to the interior of the semi-annular groove 1 73 through the telescopic air pipe 252 and the ventilation groove 72. After the semi-annular groove 1 73 is filled, it enters the interior of the semi-annular groove 2 74. Then, the gas is discharged through multiple arc-shaped air grooves 75 to impact the rubber belt 64 at the corresponding position to deform it. Because the thickness of the semi-annular groove 1 73 is less than the thickness of the semi-annular groove 2 74, when the gas enters the interior of the semi-annular groove 2 74 from the semi-annular groove 1 73, the pressure of the gas will drop sharply due to the sudden increase in volume, and the flow rate will decrease. The arc-shaped air groove 75 provides a larger flow cross-section, and the streamlines naturally diffuse, reducing local high-speed jets, and the velocity distribution tends to be uniform, so that the gas finally discharged from the arc-shaped air groove 75 is rectified into a uniform low-speed flow output, further reducing the damage to the rubber belt 64 and effectively extending the service life of the device.

[0048] Working principle: The silicone products are placed inside the crushing box 1 for crushing to form crushed materials, and then the silicone crushed materials will fall into the inside of the uniform material recovery box 2. The movable rotating shaft 63 pushes the two corresponding rubber belts 64 to form a gap. A downward inclined tilting frame is installed above the uniform material recovery box 2, and the silicone crushed materials will fall to the position between the two rubber belts 64. At this time, the rubber belt 64 above the movable rotating shaft 63 is in an inclined state. The silicone crushed materials will first contact the top of the rubber belt 64 when they are discharged from the upper part of the uniform material recovery box 2, and continue to fall to the closest distance between the two rubber belts 64 through the inclined rubber belt 64. When the silicone crushed materials pass through the closest distance between the two rubber belts 64 and are discharged, they will be discharged in a surface shape, so that the silicone crushed materials can be evenly spread on the recycling conveyor belt 4, and then discharged. It is not easy to stack up, and it also avoids the situation where the elastic recovery after stacking due to the high elasticity of silicone is aggravated by bridging. Under the power drive, the movable shaft 63 can rotate, and at this time the rubber belt 64 is tightened by the top shaft 61 and the lifting shaft 62, so the rubber belt 64 is driven to perform transmission work. The continuously transmitted rubber belt 64 will transport the falling silicone crumbs to the closest distance position between the two rubber belts 64 more quickly, and avoid the situation where the silicone crumbs stick to the outer surface of the rubber belt 64. A displacement ring 7 is movably installed in the middle position of the rotating movable shaft 63. The displacement ring 7 can move outside the circumference of the movable shaft 63, and the displacement ring 7 contacts the inner side of the rubber belt 64 at the corresponding position, thereby driving the movable shaft. The rubber belt 64 on one side of the shaft 63 is deformed, that is, the part of the rubber belt 64 corresponding to the middle of the movable rotating shaft 63 will continuously deform and recover, and the local curvature and tension of the rubber belt 64 can be periodically changed, so that the silicone crumbs are passively disturbed, dispersed, and fluidized during the falling process, and further avoid the crumbs from being connected with each other, forming clusters or bridge arches, and causing discharge blockage problems. When the silicone crumbs are evenly laid out in a surface state through the two material-distributing components 6, the lighter plastics and impurities in the silicone crumbs are blown away and collected separately through the lateral air outlet of the blowing component 5, and the remaining silicone crumbs are spread on the recovery conveyor 4 for collection and recycling, so as to facilitate the subsequent recycling process. Different silicone products are placed in the crushed material box There are certain differences in the shapes after crushing, and there are also differences in the spacing required for the crushed materials to be evenly laid out. In this device, the sliding block 231 can be moved inside the movable plate 23 to drive the adjustment motor 24 to move. At this time, the movable shaft 63 between the two corresponding adjustment motors 24 will be displaced horizontally. The two corresponding adjustment motors 24 can be set as a balance block to reduce the number of motors. While the movable shaft 63 moves in the horizontal position, the electric telescopic column 652 is extended and retracted to drive the lifting shaft 62 to move up and down, changing the horizontal height of the lifting shaft 62. Because the rubber belt 64 needs to be tightened at all times to enable the rubber belt 64 to transmit, when the movable shaft 63 moves horizontally and causes the rubber belt 64 to relax,The lifting member 65 can drive the lifting shaft 62 downward, re-stretching the rubber belt 64 and restoring its transmission state. Through this action, the distance between the two movable shafts 63 can be adjusted, that is, the minimum distance between the two rubber belts 64 can be adjusted to match different silicone scraps, further improving the collection and recovery rate of silicone scraps.
