[0002] In the recycling and processing of waste plastics, the dehydration process is crucial. If a large amount of moisture is not removed in time, it will not only affect the quality of subsequent melting and granulation but also increase storage and transportation costs.

However, these methods still have many problems in terms of processing efficiency, applicability, and operational stability.

[0003] Some traditional equipment uses a motor-driven reciprocating motion of the pressure head to achieve compaction, but due to its single-point structure and limited stroke, the compaction is uneven. Especially when the plastic is unevenly distributed or there are localized thick accumulations, it is easy to encounter problems such as insufficient compaction or incomplete compaction, resulting in high residual moisture content.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-4 An embodiment of this utility model provides a waste plastic recycling dehydrator, including a support frame 1. A first motor 5 is fixedly connected to one side of the support frame 1. A first gear 6 is fixedly connected to the output end of the first motor 5. A second gear 7 is rotatably connected to the bottom of the support frame 1. A turntable 8 is fixedly connected to the top of the second gear 7. A reciprocating disc 9 is rotatably connected to one side of the top of the turntable 8. A pull rod 10 is rotatably connected to one side of the top of the reciprocating disc 9. A through column 11 is rotatably connected to one end of the pull rod 10. A guide rod 12 is rotatably connected to one end of the through column 11. A guide rail 2 is installed on the top of the support frame 1. A dehydration tank 3 is slidably connected to the top of the guide rail 2.

[0031] Specifically, the support frame 1 adopts a welded carbon steel structure, possessing sufficient structural strength to bear the dynamic load of the entire machine. A first motor 5 is fixedly connected to one side of the support frame 1. The first motor 5 is an AC asynchronous motor with a reduction mechanism, and its output shaft is connected to a first metal gear 6 via a key to ensure reliable torque transmission. The first gear 6 achieves precise meshing transmission with a second gear 7 located at the bottom of the support frame 1 and rotatably connected to it via a bearing seat.

[0032] The upper end of the second gear 7 is fixedly connected to a turntable 8 by welding or bolting. Turntable 8 is a steel structural component with a thickness of not less than 10mm, used to support the upper motion mechanism and transmit rotational power. An eccentrically mounted shaft seat is provided at the top edge of turntable 8, through which it is hinged to a reciprocating disc 9. During the rotation of turntable 8, the reciprocating disc 9 forms a controlled reciprocating oscillating trajectory along the center of the shaft. One side of the reciprocating disc 9 is connected to a tie rod 10 via a universal joint or ball joint structure. Tie rod 10 is a solid round steel rod with a diameter of not less than 12mm, used to stably transmit reciprocating motion.

[0033] The other end of the tie rod 10 is hinged to the through column 11, which is a transversely extending member that passes horizontally between the mounting plates on both sides of the support frame 1. The end of the through column 11 is movably connected to the guide rod 12 via a pivot connection. The guide rod 12 is fixed to the end of the dehydration tank 3 via a limiting sleeve, thereby realizing the relative rotational freedom and displacement guidance function between the structures.

[0034] The support frame 1 has parallel guide rails 2 on both sides of its top. The guide rails 2 adopt a rolling linear guide rail structure (such as the THK HSR series) to provide a low-friction, high-precision sliding path. A dehydration tank 3 is slidably connected to the guide rails 2. The dehydration tank 3 is a rectangular container made of stainless steel, with multiple sets of radially distributed drainage holes at its bottom. The guide rod 12 is connected to the end of the dehydration tank 3 through a connecting block, allowing the dehydration tank 3 to achieve a specified lateral sliding range during reciprocating motion. This sliding direction is restricted by the guide rails 2, limiting it to axial movement along the guide rails 2, without swaying or tilting.

[0035] During operation, the first motor 5 starts and drives the first gear 6 to rotate, which in turn drives the second gear 7 to rotate synchronously, thereby driving the turntable 8 to rotate at a stable angular velocity. The rotation of the turntable 8 causes the eccentrically connected reciprocating disc 9 to generate a non-circular motion trajectory. Through the linkage of the pull rod 10, the through column 11, and the guide rod 12, the dewatering tank 3, which is slidably mounted on the guide rail 2, to perform reciprocating linear motion in the horizontal direction. The amplitude and frequency are determined by the eccentricity and the motor speed. This motion periodically disturbs the waste plastic material located in the dewatering tank 3, effectively breaking the adhesion between it and the residual moisture, increasing the moisture migration rate, and achieving the purpose of mechanical dewatering.

[0036] Reference Figures 1-3 The guiding component includes a guide block 4, which is fixedly connected to the top side of the support frame 1 by a vertical rod. The inner cavity of the guide block 4 includes a cone or rectangle and is perpendicular to the top side of the dehydration tank 3.

[0037] Specifically, a guiding component is located on the top side of the support frame 1 to guide upstream materials orienting them into the working area of ​​the dewatering tank 3. This guiding component includes a guiding block 4, which is a hollow structure with one open end. Its bottom is fixedly installed on the top side of the support frame 1 by a metal upright. The upright is made of rectangular cross-section steel or aluminum alloy profile, possessing good structural rigidity. Its lower end is welded or screwed to the upper frame of the support frame 1, and positioned through pre-drilled holes to ensure the spatial stability and positional accuracy of the guiding block 4.

[0038] The guide block 4 is preferably made of corrosion-resistant polyethylene or stainless steel sheet. Its internal cavity structure is designed as a conical or rectangular channel structure according to the particle size and flowability requirements of the dewatered material. The conical channel is suitable for plastic fragments with irregular shapes and large volume differences, and has an automatic guiding and concentrating function; the rectangular channel is suitable for strip-shaped and sheet-shaped plastics with high homogeneity, which is conducive to the stable transition and conveying of materials. Regardless of the cross-sectional shape, the longitudinal axis is designed to be perpendicular to the opening on the top side of the dewatering tank 3, so as to realize the vertical gravity drop of the material or buffer the flow, thereby reducing the impact of feeding and avoiding local accumulation in the dewatering tank due to uneven feeding.

[0039] The lower outlet diameter of the guide block 4 matches the top opening size of the dehydration tank 3, and an appropriate gap is reserved between its installation height and the sliding trajectory of the dehydration tank 3 to ensure no physical interference occurs during the operation of the dehydration tank 3. To ensure the guiding accuracy of the plastic material entering the dehydration tank 3, the inner surface of the guide block 4 can be designed as a smooth curved surface or coated with an anti-adhesion coating as needed, thereby reducing the adhesion of waste plastic to the inner wall when it is wet.

[0040] Reference Figures 1-3 The guide rod 12 is rotatably connected to one end of the dehydration tank 3. A cross-shaped movement groove is provided at the bottom of the dehydration tank 3, and the guide rod 12 is set on the inner wall of the cross-shaped movement groove.

[0041] Specifically, the guide rod 12 is rotatably connected to the mounting base on the side wall of the dehydration tank 3 via a pin or shaft, giving it a certain degree of angular displacement freedom during transmission. This absorbs stress deviations caused by reciprocating motion, ensuring the stability and structural integrity of the dehydration tank 3. This connection method typically employs a double-ear flange structure or a ball joint structure to achieve multi-axial displacement compensation.

[0042] To facilitate the guiding function of the guide rod 12 during lateral movement, a cross-shaped motion groove is provided at the bottom of the dehydration tank 3. This groove has guide tracks along both the length and width directions of the dehydration tank 3, and its structure consists of a cross-shaped sliding limiting groove inside the bottom plate. This motion groove can be manufactured by milling or integral pressing. The two directions inside the groove correspond to the horizontal sliding and vertical disturbance directions, respectively, to satisfy the main sliding direction of the dehydration tank 3 under the constraint of the guide rail 2, while providing the required free travel area at the end of the guide rod 12.

[0043] The guide rod 12 is disposed on the inner wall of the cross-shaped motion groove. Specifically, its end is placed inside the cross-shaped groove via a slider, ball bearing sleeve, or nylon guide block, allowing it to slide with the dehydration tank 3 as a whole. When necessary, the guide rod 12 can also compensate for movement caused by slight swaying disturbances at the bottom of the dehydration tank 3, further realizing the transmission and coordinated guidance of reciprocating drive motion to the dehydration tank 3. This structural design significantly improves the dynamic response capability and overall force balance of the dehydration tank 3 during movement, avoiding problems such as uneven load and jamming caused by single-point drive.

[0044] This structure effectively combines the mechanical freedom of the guiding mechanism with the linear motion trajectory of the dehydration tank 3, enhancing the system's compliance and mechanical stability. Furthermore, the sliding engagement between the cross-shaped motion groove and the guide rod creates a coordinated motion control mechanism that combines permissible displacement with directional control. The overall structure requires no complex sensors or control units; stable and reliable reciprocating operation of the dehydration tank 3 can be achieved through pure mechanical linkage.

[0045] Reference Figure 4 The extrusion assembly includes support rods 13, multiple support rods 13 are symmetrically installed on one side of the support frame 1, and turntables 14 are rotatably connected to the opposite side of each support rod 13. A second motor 15 is fixedly connected to one end of the support rod 13, and a connecting rod 16 is fixedly connected to one end of the turntables 14. A gravity block 17 is rotatably connected to the outer wall of the connecting rod 16.

[0046] Specifically, the extrusion assembly is located on one side of the support frame 1 and is used to apply periodic pressure to the waste plastic material located at the top of the dewatering tank 3 during the dewatering process, thereby further improving the dewatering efficiency. The extrusion assembly includes several support rods 13, which are symmetrically arranged in pairs on one side of the support frame 1 with axial spacing, and are configured in a left-right or up-down mirror configuration to ensure uniform extrusion pressure distribution and stable mechanism balance.

[0047] The support rod 13 is made of high-strength solid round steel or rectangular tubing, and its length and installation angle are preset according to the shape and sliding path of the dehydration tank 3. A second motor 15 is fixedly connected to the middle or tail end of each support rod 13. The second motor 15 is a compact small DC servo motor or stepper motor, which is fixed to the upper end of the support rod 13 by a flange or bracket, and the output shaft is set vertically.

[0048] The output end of the second motor 15 is fixedly connected to a turntable 14 via a rigid coupling or key connection. The turntable 14 adopts an eccentric wheel structure, with its shaft coaxially mounted with the motor output shaft. The outer periphery of the turntable surface is provided with a joint or threaded hole for transmission connection. A connecting rod 16 is fixedly connected to one end of each turntable 14. The connecting rod 16 is a slender steel pull arm with a universal joint structure at the front end to adapt to dynamic posture changes.

[0049] A rotatable gravity block 17 is fitted onto the other end of the connecting rod 16. The gravity block 17 is slidably and rotatably connected to the outer wall of the connecting rod 16 through a hollow bearing seat, allowing it to maintain a downward suspended state during the rotation of the connecting rod 16. The structural dimensions of the gravity block 17 are set according to the plastic load, and it is preferably made of cast iron or tungsten steel to obtain the required static load and provide a stable pressing force.

[0050] When the equipment is running, the second motor 15 starts according to a preset rhythm, driving the turntable 14 to rotate around its own axis. Since the connecting rod 16 is eccentrically mounted on the turntable surface, its rotation causes the gravity block 17 to move periodically along an elliptical or pendulum trajectory. When the dehydration tank 3 is in the rising position or at the end of its movement, the gravity block 17 swings with the connecting rod 16, pressing against its top plastic surface, forming an intermittent compaction process. Driven by both gravity and kinetic energy, the gravity block 17 has a buffering and crushing capacity, preventing excessive breakage of the plastic.

[0051] This structural design incorporates a periodic mechanical pressing device, creating active disturbances during the dehydration process, effectively mitigating the difficulty in removing residual water due to the surface tension of plastics. Compared to pure vibration dehydration, this extrusion mechanism achieves segmented compaction of points and surfaces, significantly increasing the dehydration rate per unit time, making it particularly suitable for processing soft plastics, films, or recycled materials with high liquid content.

[0052] Reference Figures 1-3 Turntable 14 passes through support rod 13 and is fixedly connected to the output end of second motor 15.

[0053] Specifically, the turntable 14 is further configured to pass through the support rod 13, meaning that the main shaft of the turntable 14 passes axially through the support rod 13, and the rotation center axis of the turntable 14 is aligned with the axial direction of the support rod 13. Specifically, the support rod 13 has a through hole in its middle that matches the main shaft of the turntable 14. This through hole is reinforced by a sleeve or bushing to enhance the structural strength of the support rod 13 and ensure rotational stability.

[0054] One end of the main shaft of turntable 14 extends to the end of support rod 13 near support frame 1, and is fixedly connected to the output shaft of second motor 15 by key connection or expansion sleeve connection to realize torque transmission and rigid drive. This "through rod" arrangement has good axis concentricity, ensuring that the turntable will not eccentrically swing under high speed or continuous operation, thereby avoiding unstable movement of connecting rod 16 and gravity block 17 during operation.

[0055] Compared to the traditional external eccentric wheel structure, this structure is more compact in layout, making it particularly suitable for applications with limited space, such as dewatering equipment, where the arrangement of dynamic components is critical. By axially inserting the turntable 14 through the support rod 13, not only is the overall lateral width of the machine reduced, but the alignment and installation process of the drive components is also simplified, improving assembly accuracy.

[0056] Furthermore, since the connection between turntable 14 and the second motor 15 is a rigid fixed connection, it can be ensured that the rotational torque is directly transmitted to turntable 14 after the motor starts, without the need for an additional coupling compensation structure, thus reducing transmission losses. This arrangement also facilitates subsequent maintenance; turntable 14 can be quickly replaced by removing the outer stop, making it easy to switch between various motion trajectories and pressure rhythms of the gravity blocks 17.

[0057] Reference Figures 1-3 One end of the gravity block 17 has a slope, which is connected to the top of the dehydration tank 3.

[0058] Specifically, the gravity block 17 is made of solid casting or machined as a whole, and its working end face is cut at a set angle to form an inclined surface, which is used to contact the top of the dehydration tank 3. This inclined surface extends along the longitudinal axis of the gravity block 17, and the inclination angle α is 15° to 30°. The specific angle can be parameterized according to the top outline of the dehydration tank 3 and the plastic stacking shape.

[0059] The core function of the slope design is that, during the periodic oscillation of the gravity block 17 around the turntable 14 with the connecting rod 16, when its end reaches the lowest point and presses against the top of the dehydration tank 3, the slope and the upper surface of the dehydration tank 3 form an inclined contact. This allows the pressure in the contact area to gradually release from the front edge to the rear edge, avoiding instantaneous impact concentration that could cause plastic breakage or damage to the tank. This inclined structure can achieve pressure gradient distribution during the stress process, effectively buffering the kinetic energy conversion during compaction and improving the operational stability of the device.

[0060] Meanwhile, the slope morphology allows the gravity block 17 to have a "slide-in-compact-slide out" transition process during contact with the dehydration tank 3, enabling continuous and flexible linear pressing of the plastic pile. Compared with the traditional planar pressure head contact structure, the slope pressing not only increases the pressing contact area and enhances the dehydration efficiency per unit time, but also forms multi-dimensional coupling with the vibration response of the top of the dehydration tank 3, further promoting the migration and discharge of attached water.

[0061] In terms of structural connections, the bottom edge of the slope is provided with a rounded transition to avoid direct hard contact between the sharp edge and the outer wall of the dehydration tank 3. At the same time, a wear-resistant pad (such as polytetrafluoroethylene or rubber sheet) can be laid at the bottom of the slope to reduce direct friction between metals and extend service life. The top of the dehydration tank 3 is a welded metal plate structure or a composite lining structure, which can withstand cyclic impact loads and has not experienced significant local buckling in actual operation.

[0062] Reference Figures 1-3 The bottom side of the dehydration tank 3 has multiple drainage holes, and storage tanks are arranged vertically around the drainage holes.

[0063] Specifically, multiple drainage holes are evenly distributed along the bottom edge of the dehydration tank 3, with the hole diameter preferably set to Φ4~8mm to balance drainage efficiency and impurity blocking function. Each drainage hole has a through structure, extending from the bottom surface of the inner cavity of the dehydration tank 3 to the outside, and is equipped with an inner chamfer to reduce the possibility of plastic residue getting stuck.

[0064] The drainage holes are located on one side of the bottom plate of the dehydration tank 3, and are arranged in groups to avoid local stress concentration or weld fatigue cracking caused by concentrated hole placement. The bottom plate is made of steel plate with a thickness of not less than 4mm, and is formed by laser drilling or mechanical drilling and milling. The hole positions are uniformly designed to facilitate subsequent modular manufacturing, maintenance and replacement.

[0065] To facilitate the unified discharge of wastewater, a storage tank is installed directly below the drain hole, in its vertical direction. This storage tank is a closed structure, entirely welded from stainless steel or polyethylene sheets. It features an upward-facing collection chamber and an inlet or manifold at the top corresponding to the drain hole, used to collect the liquid discharged from the bottom of the dewatering tank 3. The storage tank is mounted flush against the bottom support surface of the support frame 1, forming a vertical alignment with the bottom of the dewatering tank 3.

[0066] Reference Figures 1-3 The second gear 7 is meshed with the first gear 6, and the first gear 6 is rotatably connected to one end of the bottom of the support frame 1.

[0067] Specifically, in the drive system, the second gear 7 is meshed with the first gear 6. Specifically, the number of teeth and tooth profile of the first gear 6 and the second gear 7 are precisely calculated and designed to ensure smooth meshing and power transmission during rotation. The outer circumference of the first gear 6 has precision-machined teeth, which can be helical or spur, and the specific parameters of the tooth profile can be adjusted according to application requirements.

[0068] The first gear 6 is rotatably connected to one end of the bottom of the support frame 1. To achieve this connection, the bottom of the support frame 1 is provided with a pre-set mounting hole. The bearing end of the first gear 6 is inserted into this hole and fixed by a bearing, nut, or locking ring to ensure stable rotation during operation without loosening or shifting. The rotation axis of the first gear 6 is perpendicular to the support axis at the bottom of the support frame 1, thus forming a stable transmission system.

[0069] The second gear 7, through its meshing teeth with the first gear 6, transmits rotation to subsequent mechanical components. In this structural design, the second gear 7 is typically linked with other components (such as a turntable, gravity block 17, or other transmission devices) and undertakes an important driving function. The meshing relationship between the second gear 7 and the first gear 6 can be adjusted according to actual needs to control the output speed and torque, adapting to the requirements of different workloads.

[0070] Working principle: When this dewatering machine is used in a waste plastic recycling production line, firstly, align the entire device, especially the guide block 4, with the waste plastic discharge port of the previous process. Then, guided by the guide block 4, the plastic is discharged into the top side of the dewatering tank 3. Then, the first motor 5 is turned on, which drives the first gear 6 and the second gear 7 to mesh and transmit power. Simultaneously, it drives the turntable 8, the reciprocating plate 9, and the pull rod 10 to achieve a reciprocating pulling effect. This, combined with the rotational connection between the through column 11 and the guide rod 12, allows the dewatering tank 3 to reciprocate on a slope under the limitation of the guide rail 2. Thus, through the slope and the cyclic reciprocating lateral movement, the effects of dewatering and guiding the plastic discharge are achieved simultaneously.

[0071] During this process, the second motor 15 can be continuously turned on, driving the turntable 14 to rotate, thereby repeatedly driving the gravity block 17 connected to the connecting rod 16 to squeeze the plastic passing through the top of the dehydration tank 3, thus promoting drainage and improving dehydration efficiency.

[0072] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
