Description

Technical Field

[0001] This invention relates to the field of EPE waste recycling technology, specifically a waste recycling conveying device and a method for using it for EPE edge material recycling. Background Technology

[0002] EPE (expandable polyethylene), also known as pearl cotton, is a widely used cushioning packaging material with excellent properties such as light weight, flexibility, impact resistance, and heat insulation.

[0003] During the production and processing, a large amount of scrap waste is generated. To achieve resource recycling, reduce production costs, and minimize environmental pollution, it is particularly important to recycle and reprocess this EPE waste. A typical recycling process includes: waste collection, conveying, compaction (or pre-compression), crushing, and melt granulation.

[0004] In existing technologies, the recycling and conveying of EPE waste is usually carried out by using a single conveyor belt or manual feeding to guide the waste into the crusher for crushing. However, due to the extremely high bulk and elasticity of EPE material, when the waste is sent to the crusher inlet by a single conveyor belt, bridging, entanglement and blockage of the material are very likely to occur. This not only causes intermittent feeding, but also causes the crusher's working load to fluctuate drastically, resulting in frequent idling or overload shutdowns, which seriously affects the continuity and processing efficiency of the recycling line.

[0005] To address the aforementioned issues, some existing technologies have employed improved solutions using dual conveyor belts (arranged vertically). These belts initially compact the waste material before conveying it. However, since the initial thickness of the EPE waste to be processed varies and often exceeds the pre-set gap between the two belts, when the excessively thick and fluffy waste is conveyed to the inlet of this gap, it will instantly accumulate in front of the inlet because it cannot enter in time. This accumulation not only fails to form effective compaction but also quickly evolves into severe blockage, leading to a complete interruption of the conveying process and requiring a shutdown for cleaning. Summary of the Invention

[0006] The purpose of this invention is to provide a waste recycling conveying device and a method for using it for recycling EPE edge material, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A waste recycling conveying device includes: The bracket has a fixed plate, and a support plate is fixed on the fixed plate. A drive pulley is symmetrically and rotatably mounted on the bracket, and a lower conveyor belt is fitted onto the drive pulley; An adjustment component is disposed on the fixed plate. An upper conveyor belt is connected to the adjustment component. A reverse transmission mechanism connected to the adjustment component is disposed on the fixed plate. The reverse transmission mechanism can control the upper conveyor belt to perform reverse movement through the adjustment component when the transmission pulley drives the lower conveyor belt to move. A rotary pressing mechanism is provided on the receiving plate. A pressing roller is connected to the rotary pressing mechanism. A guide component connected to the rotary pressing mechanism is also provided on the receiving plate. The rotary pressing mechanism can control the pressing roller to perform a pressing action on the waste material through the guide component.

[0008] As a further aspect of the present invention: the adjusting component includes a groove formed on the fixed plate, a sliding block slidably installed in the groove, a cylinder fixedly connected to the sliding block on the fixed plate, a conveyor belt pulley rotatably installed on the sliding block, and an upper conveyor belt sleeved on the conveyor belt pulley.

[0009] As a further embodiment of the present invention: the reverse transmission mechanism includes a driving gear fixed to the end of the transmission pulley, a rotating rod rotatably mounted on the fixed plate, and a driven gear meshing with the driving gear fixed on the rotating rod; It also includes an elastic component and a transmission component disposed on the fixed plate and connected to the rotating rod.

[0010] As a further embodiment of the present invention: the elastic component includes a fixed rod fixed to the fixed plate, a support sleeve fixed to the end of the fixed rod, a support rod axially sliding inside the support sleeve, a movable plate fixed to the end of the support rod, and a spring sleeved on the support sleeve and the support rod, with the two ends of the spring abutting against the fixed rod and the movable plate respectively.

[0011] As a further embodiment of the present invention: the transmission assembly includes a support guide wheel rotatably mounted on the movable plate, and a belt connected to the rotating rod and the conveyor pulley is sleeved on the support guide wheel.

[0012] As a further embodiment of the present invention: the rotary pressing mechanism includes a drive motor fixed on the receiving plate, and a transmission rod rotatably mounted on the receiving plate and connected to the output shaft of the drive motor.

[0013] As a further embodiment of the present invention: the rotary pressing mechanism further includes a rotating sleeve fixed on the transmission rod and arranged symmetrically, a movable rod sliding axially inside the rotating sleeve, a connecting plate fixed at the end of the movable rod, and the connecting plate being rotatably connected to the pressing roller.

[0014] As a further embodiment of the present invention: the guiding component includes a fixed plate fixed on the receiving plate, a guide groove is formed on the fixed plate, a slot is formed on the outer circumferential wall of the rotating sleeve, and a limiting post is fixed on the movable rod, which passes through the slot and slides into the guide groove.

[0015] As a further embodiment of the present invention: the guide groove includes a horizontal groove, a vertical groove, and an arc groove formed on the fixed plate, the vertical groove is symmetrically arranged, and the two ends of the vertical groove are respectively connected to the ends of the horizontal groove and the arc groove.

[0016] A method for recycling EPE edge material, employing the aforementioned waste material recycling conveying device, includes the following steps: Step 1: Adjust the spacing between the upper and lower conveyor belts using the adjustment component according to the thickness of the waste material; Step 2: Place the waste material on the lower conveyor belt. The drive pulley controls the movement of the lower conveyor belt and the reverse rotation mechanism, so that the lower conveyor belt and the upper conveyor belt move synchronously in opposite directions. Step 3: Under the action of the rotating pressing mechanism and the guiding components, the movement of the pressing roller is controlled, and the waste material is pressed down, thereby guiding the waste material into the space between the lower conveyor belt and the upper conveyor belt; Step 4: Guide the waste material to the designated location under the action of the lower and upper conveyor belts.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention achieves adaptive compaction and continuous and stable conveying of loose EPE waste through the cooperation of the adjustment component and the reverse transmission mechanism. The adjustment component driven by the cylinder can adjust the distance between the upper and lower conveyor belts according to the initial loose thickness of the waste, forming a variable compaction channel. At the same time, under the action of the reverse transmission mechanism, it is ensured that the belt connecting the two remains effectively tensioned no matter how the center distance between the conveyor pulley and the drive pulley changes during the adjustment of the distance, thereby ensuring that the upper and lower conveyor belts can run stably at the same speed and in opposite directions, forming a clamping channel with the same direction of movement at the inlet.

[0018] Through the cooperation of the rotating pressing mechanism and the guiding components, the pressing roller performs a periodic compound motion. In the arc groove guiding stage, the pressing roller smoothly approaches the waste material; in the vertical groove guiding stage, the pressing roller quickly presses down to locally pre-compact the loose waste material, reducing its thickness to accommodate the conveying gap; in the horizontal groove guiding stage, while maintaining the pressing state, the pressing roller provides a horizontal forward thrust with its rotating surface, which, in conjunction with the conveying force of the lower conveyor belt, smoothly pushes the pre-compacted waste material into the compaction channel formed by the upper and lower conveyor belts.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0023] Please see Figures 1-9 In this embodiment of the invention, a waste recycling and conveying device includes: A bracket 1 is fixedly mounted on a fixing plate 5, and a receiving plate 19 is fixedly mounted on the fixing plate 5. A transmission pulley 3 is symmetrically and rotatably mounted on the bracket 1, and a lower conveyor belt 4 is sleeved on the transmission pulley 3; An adjustment component is provided on the fixed plate 5. An upper conveyor belt 28 is connected to the adjustment component. A reverse transmission mechanism connected to the adjustment component is provided on the fixed plate 5. The reverse transmission mechanism can control the upper conveyor belt 28 to perform reverse movement through the adjustment component when the transmission pulley 3 drives the lower conveyor belt 4 to move. A rotary pressing mechanism is provided on the receiving plate 19. A pressing roller 26 is connected to the rotary pressing mechanism. A guide component connected to the rotary pressing mechanism is also provided on the receiving plate 19. The rotary pressing mechanism can control the pressing roller 26 to perform a pressing action on the waste material through the guide component.

[0024] Specifically, during waste conveying, because EPE waste is inherently loose, direct conveying can lead to bridging and entanglement at the feed inlet during subsequent cutting and crushing processes, resulting in intermittent feeding, idling, or overloading of the crusher. Therefore, the waste needs to be compacted during conveying. When the waste is placed on the lower conveyor belt 4, the movement of the adjustment component can be controlled according to the initial thickness of the waste. Under the action of the adjustment component, the distance between the upper conveyor belt 28 and the lower conveyor belt 4 is adjusted. At this time, the drive pulley 3 drives the lower conveyor belt 4 and the reverse transmission mechanism to move. Under the action of the reverse transmission mechanism, the lower conveyor belt 4 and the upper conveyor belt 28 move in opposite directions at the same speed, so that the waste material moves towards the space between the lower conveyor belt 4 and the upper conveyor belt 28. At the same time, the rotating pressing mechanism moves, and under the action of the guiding component, the pressing roller 26 is controlled to move along the corresponding trajectory. Under the action of the pressing roller 26, the waste material is initially pressed down and guided into the space between the upper conveyor belt 28 and the lower conveyor belt 4. In this way, the waste material can be prevented from accumulating in front of the upper conveyor belt 28 because the initial thickness of the waste material is greater than the distance between the upper conveyor belt 28 and the lower conveyor belt 4.

[0025] Please seeFigures 1-5 , Figure 7 The adjusting component includes a groove 501 formed on the fixed plate 5, a sliding block 6 is slidably installed in the groove 501, a cylinder 7 fixedly connected to the sliding block 6 is fixed on the fixed plate 5, a conveyor belt pulley 8 is rotatably installed on the sliding block 6, and the upper conveyor belt 28 is sleeved on the conveyor belt pulley 8.

[0026] Please see Figures 1-4 , Figure 7 , Figure 8 The reverse transmission mechanism includes a drive gear 9 fixed to the end of the transmission pulley 3, a rotating rod 10 rotatably mounted on the fixed plate 5, and a driven gear 11 meshing with the drive gear 9 fixed on the rotating rod 10; it also includes an elastic component and a transmission component disposed on the fixed plate 5 and connected to the rotating rod 10. The elastic component includes a fixed rod 12 fixed on the fixed plate 5, a support sleeve 13 fixed to the end of the fixed rod 12, a support rod 14 axially sliding inside the support sleeve 13, a movable plate 15 fixed to the end of the support rod 14, and a spring 16 sleeved on the support sleeve 13 and the support rod 14, with both ends of the spring 16 abutting against the fixed rod 12 and the movable plate 15 respectively. The transmission component includes a support guide wheel 17 rotatably mounted on the movable plate 15, and a belt 18 connected to the rotating rod 10 and the conveyor pulley 8 sleeved on the support guide wheel 17.

[0027] In detail, a drive motor 2 is fixed on the bracket 1, and one of the transmission pulleys 3 is connected to the output shaft of the drive motor 2. In the initial state, under the action of the cylinder 7, the sliding block 6 is located at the end of the stroke of the slide groove 501 away from the bracket 1, so that the distance between the upper conveyor belt 28 and the lower conveyor belt 4 is maximized. In this state, the distance between the conveyor pulley 8 and the transmission pulley 3 is maximized. The support rod 14 is located at the end of its stroke near the support sleeve 13, where the distance between the movable plate 15 and the fixed rod 12 is the smallest. The spring 16 has an elongation greater than the maximum length of the combination of the support rod 14 and the support sleeve 13 in its natural state. Therefore, the spring 16 is in a pre-compressed state and always provides the movable plate 15 with a thrust away from the fixed rod 12. Under the action of the movable plate 15, the belt 18 is kept taut by the support guide wheel 17 to ensure that when the rotating rod 10 rotates, the support guide wheel 17 and the conveyor belt pulley 8 can rotate synchronously through the belt 18. The driving gear 9 and the driven gear 11 mesh with each other, so that the rotation direction of the rotating rod 10 is opposite to that of the transmission pulley 3, and the rotation direction of the transmission pulley 3 is opposite to that of the conveyor belt pulley 8, thereby controlling the movement direction of the upper conveyor belt 28 and the lower conveyor belt 4 to be opposite. When conveying waste, the distance between the upper conveyor belt 28 and the lower conveyor belt 4 needs to be adjusted according to the thickness of the waste. In this regard, the cylinder 7 is activated, and its telescopic end pushes the sliding block 6 to move along the slide groove 501 on the fixed plate 5 toward the direction of the support 1. This movement causes the conveyor belt wheel 8 fixed on the sliding block 6 to move closer to the transmission wheel 3, thereby continuously reducing the vertical distance between the upper conveyor belt 28 sleeved on the conveyor belt wheel 8 and the lower conveyor belt 4 sleeved on the transmission wheel 3 until the distance is less than the initial fluffy thickness of the waste to be processed. During this adjustment process, as the center distance between the two pulleys shortens, the belt 18 connecting the rotating rod 10 and the conveyor pulley 8 tends to loosen. At this time, the spring 16, which is in a pre-compressed state, releases its stored elastic potential energy, pushes the movable plate 15 to overcome frictional resistance, and drives the support rod 14 to move away from the fixed rod 12 along the axial direction of the support sleeve 13. The movement of the movable plate 15 causes the support guide wheel 17 mounted on it to move synchronously, thereby tensioning the belt 18 connecting the rotating rod 10 and the conveyor pulley 8, ensuring that the belt 18 still maintains the tension required for effective transmission after the spacing changes. When the spacing adjustment is completed and the drive motor 2 is started, the transmission pulley 3 begins to rotate, driving the lower conveyor belt 4 to move in the specified direction, conveying the loose waste material placed on it towards the upper conveyor belt 28. At the same time, the drive gear 9 fixed at the end of the transmission pulley 3 drives the driven gear 11 and the rotating rod 10 fixed thereto to rotate in the opposite direction through meshing. The reverse rotation of the rotating rod 10 is transmitted to the conveyor pulley 8 through the belt 18, forcing the conveyor pulley 8 to rotate in the opposite direction to the transmission pulley 3, thereby driving the upper conveyor belt 28 to move in the opposite direction to the lower conveyor belt 4. Since the upper conveyor belt 28 and the lower conveyor belt 4 are distributed in parallel, the surfaces of the belts moving in opposite directions form a bidirectional conveying channel with the same direction of movement at the inlet. When the waste enters between the upper conveyor belt 28 and the lower conveyor belt 4, it can continuously provide a compaction effect on the waste during the movement of the waste, thereby achieving stable and continuous initial compression of the waste. Among them, a support plate is fixedly installed on the bracket 1 and the fixing plate 5 respectively. Under the action of the support plate, the upper conveyor belt 28 and the lower conveyor belt 4 are supported, preventing the upper conveyor belt 28 and the lower conveyor belt 4 from excessive deformation or dent when compacting loose waste, thus ensuring the effective transmission and uniform distribution of the compaction force.

[0028] Please see Figures 1-3 , Figure 6 , Figure 9, the rotation and pressing mechanism includes a drive motor 20 fixed on the receiving plate 19. A drive rod 21 connected to the output shaft of the drive motor 20 is rotatably installed on the receiving plate 19. The rotation and pressing mechanism further includes rotating sleeves 23 fixed on the drive rod 21 and arranged symmetrically. An active rod 24 axially slides within the rotating sleeve 23. A connecting plate 25 is fixed to the end of the active rod 24. The connecting plate 25 is rotatably connected to the pressing roller 26. The guiding component includes a fixed disk 22 fixed on the receiving plate 19. A guiding groove is formed on the fixed disk 22. A clamping groove 2301 is formed on the circumferential outer wall of the rotating sleeve 23. A limiting column 27 fixed on the active rod 24 penetrates through the clamping groove 2301 and is slidably engaged with the guiding groove. The guiding groove includes a horizontal groove 2201, a vertical groove 2202, and an arc groove 2203 formed on the fixed disk 22. The vertical grooves 2202 are arranged symmetrically. The two ends of the vertical groove 2202 are respectively connected to the ends of the horizontal groove 2201 and the arc groove 2203.

[0029] Please refer to Figure 9 , further, the vertical grooves 2202 are arranged symmetrically and are distributed on both sides of the horizontal groove 2201 in a left - right manner. In this regard, the horizontal groove 2201, the vertical grooves 2202, and the arc groove 2203 combine to form a "mouth" - shaped groove body with an arc - shaped end. The center of the arc groove 2203 coincides with the axis of the drive rod 21, and the radius of the arc groove 2203 is smaller than the minimum distance between the drive rod 21 and the horizontal groove 2201; In the initial state, the limiting column 27 is located at the end of the stroke on the side of the arc groove 2203 away from the horizontal groove 2201. Under the action of the limiting column 27 and the arc groove 2203, the size of the mutual nesting between the active rod 24 and the rotating sleeve 23 is the largest, and the active rod 24 will control the pressing roller 26 to be located at the end of the stroke in the direction close to the drive rod 21 through the connecting plate 25; When it is necessary to compact the waste material, in order to prevent the waste material from accumulating and blocking at the entrance due to its initial loose thickness being greater than the adjusted distance between the upper conveyor belt 28 and the lower conveyor belt 4 and being unable to smoothly enter the compaction area, the drive motor 20 operates. The output shaft of the drive motor 20 drives the drive rod 21 to start rotating, and the rotating sleeves 23 fixed on the drive rod 21 rotate synchronously. This rotational movement causes the rotating sleeve 23 and the active rod 24, the connecting plate 25, and the pressing roller 26 axially sliding inside it to rotate around the axis of the drive rod 21 as a whole; In the initial stage, since the limiting column 27 fixed on the active rod 24 slides within the arc groove 2203 of the fixed disk 22, the movement trajectory of the pressing roller 26 is determined by the arc contour of the arc groove 2203, causing it to rotate around the drive rod 21 with a constant radius and smoothly move towards the waste material area on the lower conveyor belt 4; When the limiting post 27 moves with the revolution of the rotating sleeve 23 to the junction of the arc groove 2203 and one of the vertical grooves 2202, under the forced guidance of the contour of the vertical groove 2202, the limiting post 27 disengages from the arc groove 2203 and begins to slide along the vertical groove 2202. Under the action of the limiting post 27 and the vertical groove 2202, the movable rod 24 slides rapidly axially relative to the rotating sleeve 23. The movable rod 24 drives the connecting plate 25 and the lower pressure roller 26 to extend rapidly along the axial direction of the rotating sleeve 23 away from the bottom of the rotating sleeve 23 until it contacts the surface of the waste material. Under the action of the lower pressure roller 26, the waste material is initially compacted to reduce its thickness. When the limiting post 27 moves to the junction position of the vertical groove 2202 and the horizontal groove 2201, the waste material reaches its minimum thickness. During the sliding within the transverse groove 2201, since the trajectory of the transverse groove 2201 is parallel to the horizontal plane, the movable rod 24 no longer undergoes axial displacement relative to the rotating sleeve 23, and the lower pressure roller 26 remains in the maximum extended position, with its lowest point located in the compaction channel entrance area between the upper conveyor belt 28 and the lower conveyor belt 4. At this time, since the rotation direction of the transmission rod 21 is coordinated with the tangential direction of the conveyor belt pulley 8 driving the upper conveyor belt 28, the continuously rotating lower pressure roller 26, while maintaining contact with the waste material, also provides the waste material with a horizontal forward tangential friction force on its circumferential surface, forming a boosting force towards the entrance direction between the upper conveyor belt 28 and the lower conveyor belt 4. This boosting force works in conjunction with the conveying force of the lower conveyor belt 4 to smoothly push the pre-compacted waste material into the compaction channel formed by the upper conveyor belt 28 and the lower conveyor belt 4. When the limiting post 27 slides along the horizontal groove 2201 to the junction with the vertical groove 2202 on the other side and enters the vertical groove 2202, the contour of the vertical groove 2202 guides the limiting post 27 to move again. At this time, the movable rod 24 begins to slide in the opposite axial direction relative to the rotating sleeve 23, driving the lower pressure roller 26 to retract along the axial direction of the rotating sleeve 23, so that it gradually rises and leaves the compaction channel area. In this way, under the guidance of the vertical groove 2202, it is ensured that the lower pressure roller 26 has enough space to rise under the upper conveyor belt 28, thereby avoiding interference or collision with the upper conveyor belt 28 moving above during the rotation reset process. When the limiting post 27 re-enters the arc groove 2203 from the vertical groove 2202, the lower pressure roller 26 returns to its initial lifting position, completing a complete pressing-boosting-resetting cycle. In this way, during continuous conveying, the lower pressure roller 26 can periodically pre-compact and assist in the introduction of each newly entering loose waste material, ensuring the continuity of material conveying and the stability of the compaction process, and providing uniform and dense feeding conditions for subsequent crushing processes.

[0030] A method for recycling EPE edge material, employing the aforementioned waste material recycling conveying device, includes the following steps: Step 1: Adjust the spacing between the upper conveyor belt 28 and the lower conveyor belt 4 using the adjusting component according to the thickness of the waste material; Step 2: Place the waste material on the lower conveyor belt 4. The drive pulley 3 controls the movement of the lower conveyor belt 4 and the reverse rotation mechanism, so that the lower conveyor belt 4 and the upper conveyor belt 28 move synchronously in opposite directions. Step 3: Under the action of the rotating pressing mechanism and the guiding component, the movement of the pressing roller 26 is controlled, and the waste material is pressed down, thereby guiding the waste material into the space between the lower conveyor belt 4 and the upper conveyor belt 28; Step 4: Under the action of the lower conveyor belt 4 and the upper conveyor belt 28, the waste material is guided to move to the designated position.
