[0001] This utility model relates to the field of plastic processing equipment, and in particular to an expandable high-speed friction washing machine spindle. Background Technology

[0002] A high-speed friction washing machine for plastics is a specialized device for cleaning plastic waste. It uses the friction between high-speed rotating friction plates and the inner wall to quickly remove dirt, grease, and impurities from the plastic surface. This equipment is commonly used in the plastic recycling industry, effectively improving cleaning efficiency and ensuring that plastic waste reaches the required cleanliness level before reprocessing. It is suitable for various sizes and types of plastic materials.

[0003] However, existing equipment often encounters the following problems during use:

[0004] Traditional cleaning equipment cannot effectively handle plastic blocks of various sizes, especially when the material dimensions vary significantly. Traditional washing machines suffer from poor or uneven cleaning results because they cannot precisely adjust the gap between the main shaft and the inner wall. Utility Model Content

[0005] The main objective of this invention is to provide an expandable high-speed friction washing machine spindle to effectively solve the problem mentioned in the background art: existing traditional washing equipment cannot effectively handle plastic blocks of various sizes, especially when the material size fluctuates significantly. Traditional washing machines suffer from poor or uneven cleaning results because they cannot precisely adjust the gap between the spindle and the inner wall. The present invention designs a stretching cylinder that drives the force-applying shaft axially. The inclined surfaces of the inclined extrusion block and the expansion block cooperate to drive the spindle housing radially, making the gap between the friction plate and the inner wall of the friction machine adjustable. Through this adjustable spindle expansion mechanism, it can automatically adjust according to the size of the plastic block, ensuring efficient operation regardless of whether the plastic block is large or small. This improves the adaptability of the equipment, reduces the workload of manual adjustments, and allows the equipment to maintain high efficiency under different processing requirements.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A scalable high-speed friction washer spindle, comprising:

[0008] Fixed baffle;

[0009] A directional shaft is fixedly disposed on one side of the fixed baffle;

[0010] A force-applying shaft, one end of which is axially provided with a cavity, the cavity of which is sleeved onto one end of the directional shaft;

[0011] A circumferential baffle, the circumferential baffle being fixed to the extending direction of one side of the force-applying shaft;

[0012] A tension cylinder is fixedly mounted on one side of a circumferential baffle, and the output end of the tension cylinder is drivenly connected to the other end of the force-applying shaft.

[0013] An inclined extrusion block is provided in multiple sets, with three inclined extrusion blocks forming a set. The three inclined extrusion blocks are evenly distributed around the outer periphery of the force-applying shaft, and the force-applying shaft of each set is arranged along the axial direction of the force-applying shaft.

[0014] A force-applying inclined surface is formed on the top surface of each of the inclined extrusion blocks;

[0015] An extension component, which is sleeved onto the force-applying shaft.

[0016] The extended component also includes:

[0017] An extension block is provided, which is corresponding to each of the extension blocks. The extension block is provided with a stress slope that cooperates with the force-applying slope.

[0018] The stress slope is formed on the bottom surface of the expansion block;

[0019] The number of main shaft housings corresponds to the number of inclined extrusion blocks in each group, and the inner wall of the main shaft housing is fixedly connected to the extension block.

[0020] Friction plate, the outer wall of each set of spindle housings is provided with the friction plate;

[0021] Guide grooves are provided on the other side of the circumferential baffle, and the number of guide grooves corresponds to the number of main shaft housings.

[0022] The sliders are arranged one-to-one with the guide grooves. One side of each slider is fixedly connected to a spindle housing, and the other side of each slider is slidably disposed in the guide groove.

[0023] The inclined surface of the inclined extrusion block is set at a 30° angle to the axis of the directional shaft.

[0024] The second stress slope of the extension block is set at a 30° angle to the radial direction of the main shaft housing.

[0025] The guide groove is a straight groove structure extending along the side wall of the circumferential baffle.

[0026] Each of the guide grooves extends outward from the central axis of the circumferential baffle.

[0027] Compared with existing technologies, the beneficial effects of this invention are as follows: When the stretching cylinder of this invention drives the force-applying shaft to move axially, the inclined surfaces of the inclined extrusion block and the expansion block drive the main shaft housing to expand radially, making the gap between the friction plate and the inner wall of the friction machine adjustable. Through the adjustable main shaft expansion mechanism, it can automatically adjust according to the size of the plastic block, thus ensuring that the equipment can work efficiently regardless of whether it is processing large or small pieces of plastic. This improves the adaptability of the equipment, enabling it to maintain high efficiency under different processing requirements. Attached Figure Description

[0033] 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.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figure 1-3 As shown, this utility model provides an expandable high-speed friction washing machine spindle, which includes a fixed baffle 1, a directional shaft 2, a force-applying shaft 3, a circumferential baffle 4, a stretching cylinder 5, an inclined extrusion block 6, a force-applying inclined surface 7, and an extension component 8.

[0036] The fixed baffle 1 serves as the static reference for the main shaft. It is made of high-strength cast iron, such as HT250, and is bolted to the equipment base. It bears the dynamic load during high-speed rotation. The directional shaft 2 is fixedly mounted on one side of the fixed baffle 1. The directional shaft 2 is welded to the fixed baffle 1 and has a hard chrome plating thickness of 0.05mm, achieving a hardness of HRC60. This ensures that the straightness error of the axial movement of the force-applying shaft 3 is ≤0.01mm, preventing uneven wear of the friction plate 84 due to eccentric loading. The directional shaft 2 not only provides stable support but also guides the movement of the force-applying shaft 3, ensuring that it can move in the correct direction and preventing misalignment or jamming. This design guarantees efficient and precise mechanical operation, reducing energy waste and mechanical failures.

[0037] In this invention, one end of the force-applying shaft 3 is axially provided with a cavity, which is sleeved on one end of the directional shaft 2. The force-applying shaft 3 is one of the core components; one end of it has a cavity that engages with the directional shaft 2, and the other end is driven to move by the tension cylinder 5. The function of the force-applying shaft 3 is to transmit force to the inclined extrusion block 6 through the drive of the cylinder. The cooperation between the force-applying shaft 3 and the directional shaft 2 ensures that it can stably perform axial displacement during operation. The tension cylinder 5 drives the inclined extrusion block 6 through the movement of the force-applying shaft 3 to achieve force transmission, thereby efficiently extruding and cleaning the plastic. The design of the force-applying shaft 3 ensures the smoothness and efficiency of force transmission and is a core component for achieving scalability.

[0038] In this invention, the circumferential baffle 4 is fixed to one side of the force-applying shaft 3 in its extending direction. The circumferential baffle 4 not only supports the force-applying shaft 3 but also provides a fixed position for the stretching cylinder 5. Its design helps maintain the stability of the entire structure and ensures an appropriate distance between the force-applying shaft 3 and the inclined extrusion block 6. As a structural support component in the system, the circumferential baffle 4 undertakes the function of fixing the stretching cylinder 5 and the force-applying shaft 3, ensuring a stable connection between the cylinder and the shaft. During the extension process, the circumferential baffle 4 ensures the correct fit between the force-applying shaft 3 and the inclined extrusion block 6, avoiding structural instability or misalignment, thereby ensuring the accuracy and efficiency of the friction cleaning process.

[0039] In this invention, a stretching cylinder 5 is fixedly mounted on one side of the circumferential baffle 4, and its output end is drivenly connected to the other end of the force-applying shaft 3. The stretching cylinder 5 controls the displacement of the force-applying shaft 3 to extend and retract the main shaft. The cylinder not only provides displacement power but also adjusts the extension degree of the main shaft by regulating the air pressure, allowing it to accommodate plastic blocks of different sizes. Its precise control ensures fine adjustment of the cleaning process, thereby maximizing the cleaning efficiency of the washing machine.

[0040] In this invention, multiple sets of inclined extrusion blocks 6 are provided, with three inclined extrusion blocks 6 forming a group. These three inclined extrusion blocks 6 are evenly distributed around the outer periphery of the force-applying shaft 3, with each group of force-applying shaft 3 arranged along its axial direction. The force-applying inclined surface 7 of the inclined extrusion block 6 forms a 30° angle with the axis of the directional shaft 2. The even distribution of three inclined extrusion blocks 6 in each group creates mechanical symmetry, avoiding stress concentration at single points. The expansion block 81 is welded integrally with the inner wall of the main shaft housing 83. As a key component in the main shaft expansion process, the inclined extrusion blocks 6 are designed in multiple sets, with three blocks evenly distributed around the force-applying shaft 3. Their inclined surface design forms a 30° angle with the axis of the directional shaft 2, providing appropriate torque so that the axial force generated by the force-applying shaft 3 under the action of the stretching cylinder 5 is effectively converted into expansion force. Through precise friction and stress transmission, the inclined extrusion blocks 6 ensure smooth and effective expansion of the expansion block 81 and the main shaft housing 83.

[0041] In this invention, the force-applying inclined surface 7 is formed on the top surface of each inclined extrusion block 6, and the extension component 8 is sleeved on the force-applying shaft 3. The extension component includes: an extension block 81 corresponding to each extension block 81, and an extension block 81 having a stress inclined surface 82 that cooperates with the force-applying inclined surface 7; the second stress inclined surface 82 of the extension block 81 is set at a 30° angle to the radial direction of the main shaft housing 83. The extension block 81 cooperates with the force-applying inclined surface 7, and the extension block 81 expands outward by being pushed by the force-applying shaft 3, thereby causing the main shaft housing 83 to change. The 30° angle design between the second stress inclined surface 82 of the extension block 81 and the radial direction of the main shaft housing 83 not only provides an efficient force transmission method, but also ensures the stability of the main shaft housing 83 during the expansion process, preventing deformation and uneven expansion. By precisely controlling the outer diameter of the main shaft housing 83, the extension component 8 allows the washing machine to flexibly adjust according to the volume change of the washing material to ensure efficient cleaning. The stress inclined surface 82 is formed on the bottom surface of the extension block 81.

[0042] In this invention, the number of main shaft housings 83 corresponds to the number of inclined extrusion blocks 6 in each group. The inner wall of the main shaft housing 83 is fixedly connected to the extension block 81. The connection between the main shaft housing 83 and the extension block 81 ensures efficient transmission of the extension action under the drive of the force shaft 3. The extension of the main shaft housing 83 directly affects the cleaning efficiency of the washing machine. After the outer diameter of the main shaft housing 83 is increased, the gap between the friction plate 84 and the inner wall of the machine is reduced, which can more effectively perform friction cleaning on small plastic particles. The design of the main shaft housing 83 ensures the stability of the structure, so that the main shaft maintains consistency during the extension process and does not generate unnecessary vibration or jamming. Each group of main shaft housings 83 is provided with a friction plate 84 on its outer wall.

[0043] In this invention, guide grooves 85 are formed on the other side of the circumferential baffle 4, and the number of guide grooves 85 corresponds to the number of main shaft housings 83. Each guide groove 85 is a straight groove structure extending along the side wall of the circumferential baffle 4, with the central axis of the circumferential baffle 4 as the midpoint. Slider blocks 86 are arranged one-to-one with the guide grooves 85. One side of each slider 86 is fixedly connected to a main shaft housing 83, and the other side of each slider 86 is slidably disposed within the guide groove 85. The sliding of the sliders 86 within the guide grooves 85 ensures the stability of the main shaft housing 83 during the expansion process. The straight groove structure of the guide grooves 85 extends along the circumferential baffle 4, effectively guiding the sliders 86 along a predetermined path and preventing them from deviating from the track. The fixed connection between the sliders 86 and the main shaft housing 83 ensures that the outer diameter of the main shaft can expand uniformly, thereby ensuring that the change in the gap between the friction plate 84 and the inner wall of the machine during the friction cleaning process is stable and controllable.

[0044] It should be noted that, in the use of the expandable high-speed friction washing machine spindle designed in this utility model, when the volume of the plastic block to be cleaned is small, the tension cylinder 5 is activated. The output end of the cylinder pulls the force-applying shaft 3. Under the guidance of the directional shaft 2 sleeved at one end, the force-applying shaft 3 is axially displaced towards the position of the cylinder, driving each set of inclined extrusion blocks 6 set on the rod body. The inclined extrusion blocks 6 slide and extrude their force-applying inclined surface 7 and the stress inclined surface 82 of the extension block 81 that is attached to it above. The extension block 81 expands outward and drives the inner wall of the spindle housing 83 that is fixedly connected to it. The spindle housing 83 expands outward and drives the slider 86 that is fixedly connected at one end. Each slider 86 slides outward and expands in each guide groove 85 on one side of the circumferential baffle 4. The expansion of each spindle housing 83 outward increases the outer diameter of the spindle housing 83. The increase in the outer diameter of the spindle housing 83 means that the gap between the friction plate 84 of the housing body and the inner wall of the friction machine is reduced, thereby effectively processing small-volume plastic particles.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
