Description

Technical Field

[0001] This utility model relates to the field of flow guiding equipment technology, specifically to a lubricant flow guiding device. Background Technology

[0002] Lubricants are plastic additives used to reduce the frictional resistance of friction pairs and slow down their wear. Lubricants also play a role in cooling, cleaning, and preventing contamination of friction pairs. There are two types: internal lubricants and external lubricants. External lubricants mainly improve the friction between the plastic melt and the metal surface of the molding equipment, reducing the frictional force between them and making the plastic parts easier to demold. Internal lubricants work inside the plastic melt to reduce intermolecular cohesive forces, which can reduce the internal friction of the plastic melt, increase the melting rate and melt deformability, reduce melt viscosity, and improve plasticizing properties.

[0003] In the production process of lubricants, a flow guiding device is usually required to guide various raw materials into the mixing tank for mixing. Most existing feeding connection devices are of the straight cylindrical structure. Due to the lack of necessary flow guiding structure, the straight cylindrical feeding structure is prone to wall adhesion or "arch bridge" effect on the inner wall of the connecting cylinder, which leads to the accumulation of agglomerated materials and blockage of the feeding structure. Dealing with blockage requires stopping the machine for disassembly, which is time-consuming and labor-intensive, and greatly reduces the mixing efficiency of subsequent materials. Utility Model Content

[0004] In view of this, the present invention provides a lubricant guiding device, which can achieve efficient unblocking and dispersing of materials falling inside the connecting cylinder through the elastic support and the guiding cover. This solves the problem that the traditional straight-cylinder feeding structure lacks the necessary guiding structure, which easily causes the material to stick to the inner wall of the connecting cylinder or form an "arch bridge" effect, resulting in the accumulation of agglomerated material and blockage of the feeding structure. Dealing with the blockage requires stopping the machine for disassembly, which is time-consuming and labor-intensive, and greatly reduces the efficiency of subsequent material mixing and production.

[0005] To solve the above-mentioned technical problems, this utility model provides a lubricant guiding device, including a connecting cylinder. One end of the connecting cylinder is connected to the outlet of the material storage tank, and the other end is connected to the inlet of the mixing tank. A feeding cylinder extending into the inlet is provided inside the connecting cylinder. A fixing plate is provided between the outer wall of the feeding cylinder and the inner wall of the connecting cylinder. An elastic support is provided on the outer wall of the feeding cylinder, and a guide shroud is provided on the upper part of the elastic support. The elastic support can vibrate up and down under the impact of the material entering the guide shroud. This utility model can achieve rapid and efficient material guiding and feeding operations by using the elastic support in the guiding device in conjunction with the guide shroud to vibrate up and down under the impact of the material falling. It can also achieve the dispersing of agglomerated materials, greatly improving the material feeding efficiency.

[0006] The elastic support includes a slide rail mounted on the outer wall of the feed cylinder, a slider slidably mounted inside the slide rail, a connecting plate mounted on the inner wall of the slider, the upper part of the connecting plate being mounted on the lower part of the guide shroud, and an elastic element mounted on the lower part of the slider, the lower part of the elastic element being mounted on the bottom inner wall of the slide rail. This invention allows the elastic element to be compressed under the impact of an external force. The compressed elastic element, under its own restoring elastic force, pushes the guide shroud up and down, achieving rapid and efficient guidance of falling materials and dispersing of agglomerated materials. This effectively avoids blockage during the falling process of agglomerated materials and greatly improves the material feeding efficiency.

[0007] The elastic element is a spring, but it can also be a tin bronze spring.

[0008] There are multiple elastic support components, which are evenly distributed on the outer wall of the feed cylinder. This is to facilitate a firm and stable elastic support for the flow guide.

[0009] Multiple transparent observation windows are spaced apart on the side wall of the connecting cylinder, which facilitates real-time monitoring of the material inside the cylinder, making the operation more convenient.

[0010] The flow guide is an inverted cone-shaped structure, which is designed to create a certain slope to facilitate the smooth descent of materials.

[0011] The vertical inner wall of the connecting plate is slidably mounted on the outer wall of the feed cylinder, and the upper part of the horizontal part of the connecting plate is fixed together with the lower part of the guide shroud.

[0012] There are two slide rails, located on the outer walls of the feed cylinders on both sides of the connecting plate. This design effectively prevents the radial oscillation of the spring, allowing the guide shroud to vibrate only up and down. This avoids excessive axial oscillation that could affect the lifespan of the spring, and also prevents it from hitting the side wall of the connecting cylinder due to excessive axial oscillation, which could cause jamming or deformation. This greatly improves the flow guiding effect and lifespan of the guide shroud.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. Highly efficient dispersion and anti-clogging: This utility model can disperse clumps of material by reciprocating vibration of the guide shroud, and avoid accumulation by conical guide surface, which greatly reduces the material blockage rate and shortens the blockage treatment time.

[0014] 2. Improve feeding efficiency: This utility model can reduce material adhesion to the wall and the "arch bridge" effect by combining an inverted conical guide shroud with directional vibration, which greatly improves feeding efficiency and can fully meet the feeding needs of the mixing tank.

[0015] 3. Real-time monitoring and convenient operation and maintenance: This utility model can visualize the internal status through a transparent observation window, which greatly shortens the response time for abnormal situations and reduces the risk of equipment overload.

[0016] 4. Stable structure and extended service life: This utility model can constrain radial swing through double slide rails, eliminating the impact phenomenon of the cylinder wall on the guide shield, greatly improving the replacement cycle of elastic components, and significantly reducing component maintenance costs.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] like Figure 1-4As shown: This embodiment provides a lubricant guiding device, including a connecting cylinder 100. One end of the connecting cylinder 100 is connected to the outlet of a material storage tank, and the other end is connected to the inlet of a mixing tank. An inlet cylinder 200 extending into the inlet is provided inside the connecting cylinder 100. A fixing plate 300 is provided between the outer wall of the inlet cylinder 200 and the inner wall of the connecting cylinder 100. An elastic support member 400 is provided on the outer wall of the inlet cylinder 200, and a guide shroud 500 is provided on the upper part of the elastic support member 400. The elastic support member 400 can vibrate up and down under the impact of the material entering the guide shroud 500. Specifically, the connecting cylinder 100 is made of Q345B low-alloy high-strength steel, possessing anti-deformation and corrosion-resistant properties. Flanges are provided at both ends, and the flanges are connected to the outlet of the material storage tank and the inlet of the mixing tank respectively by bolts. The side walls are spaced 3-4... There is one mounting hole for the feed cylinder 200, made of the same material as the connecting cylinder 100. One end extends into the feed inlet of the mixing tank, and the other end is located in the middle section of the connecting cylinder 100. The outer wall is fixed to the inner wall of the connecting cylinder 100 by welding 3-4 fixing plates 300 made of Q235 steel. The fixing plates 300 are evenly distributed radially to ensure stable support. The guide shroud 500 is made of 304 stainless steel, which has excellent rust resistance and a smooth surface, reducing material adhesion to the wall. The overall shape is an inverted cone (e.g., the cone surface slope is 30°-45°), which facilitates the smooth sliding of materials along the cone surface. The lower part is fixed to the connecting plate 430. This utility model can use the elastic support 400 in the guide device to work with the guide shroud 500 to vibrate up and down under the impact of the falling material, thereby realizing the rapid and efficient guiding and feeding operation of the material. It can also realize the shaking and breaking of material agglomeration, greatly improving the material feeding efficiency.

[0021] According to one embodiment of the present invention, such as Figure 1-4As shown, the elastic support 400 includes a slide rail 410 disposed on the outer wall of the feed cylinder 200, a slider 420 slidably disposed within the slide rail 410, a connecting plate 430 disposed on the inner wall of the slider 420, the upper part of the connecting plate 430 being disposed at the lower part of the guide shroud 500, and an elastic element 440 disposed at the lower part of the slider 420, the lower part of the elastic element 440 being disposed on the bottom inner wall of the slide rail 410. Specifically, the slide rail 410 is made of 40Cr alloy structural steel, quenched (hardness HRC50-55), and hard chrome plated to enhance wear resistance. Each group has two slide rails 410, located on the outer wall of the feed cylinder 200 on both sides of the connecting plate 430, respectively. The slide rail 410 has a sliding groove on its inner side. The slider 420 is made of the same material as the slide rail 410 and slides within the sliding groove, allowing it to slide up and down along the slide rail 410. The connecting plate 430 is welded to its inner wall. The connecting plate 430 is made of Q345B steel. The steel component, shaped like an "L", has its vertical inner wall slidingly fitted against the outer wall of the feed cylinder 200, while the upper part of the horizontal component is fixed to the lower part of the guide shroud 500 by welding. The elastic element 440 can be of two types: either a TC80 compression spring (60Si2Mn alloy spring steel) from Shanghai Chunri Machinery Industry Co., Ltd., or a T1 type tin bronze elastic sheet (QSn6.5-0.1) from Luoyang Copper Processing Group. The upper part of the elastic element 440 abuts against the lower part of the slider 420, and the lower part is fixed to the inner wall of the bottom of the slide rail 410. This invention allows the elastic element 440 to be compressed under the impact of external force. The compressed elastic element 440, under its own restoring elastic force, pushes the guide shroud 500 up and down, achieving rapid and efficient guidance of falling materials and dispersing of agglomerated materials. This effectively avoids blockage during the falling process of agglomerated materials and greatly improves the material feeding efficiency.

[0022] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the elastic element 440 is a spring, or it can be a tin bronze spring.

[0023] There are multiple elastic support members 400, which are evenly distributed on the outer side wall of the feed cylinder 200. This is to facilitate a firm and stable elastic support for the flow guide shroud 500.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 2As shown, multiple transparent observation windows 110 are spaced apart on the side wall of the connecting cylinder 100. The transparent observation windows 110 are made of tempered borosilicate glass, which can withstand temperatures from -30℃ to 300℃, has high compressive strength, and a light transmittance of over 90%. The observation windows are sealed to the mounting holes on the side wall of the connecting cylinder 100 via flanges, and the edges are sealed with oil-resistant rubber rings to prevent leakage. The transparent observation windows 110 facilitate real-time observation of the material inside the connecting cylinder 100, making the operation more convenient.

[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the flow guide 500 has an inverted conical structure. The purpose of this is to facilitate the formation of a certain slope, which makes it easier for materials to fall smoothly.

[0026] The vertical inner wall of the connecting plate 430 is slidably mounted on the outer wall of the feed cylinder 200, and the upper part of the horizontal part of the connecting plate 430 is fixed together with the lower part of the guide shroud 500.

[0027] There are two slide rails 410, which are located on the outer side walls of the feed cylinders 200 on both sides of the connecting plate 430. The purpose of this is to effectively avoid the radial swing of the spring, so that the guide shroud 500 can only vibrate up and down. This avoids excessive axial swing that could affect the service life of the spring, and also prevents it from hitting the side wall of the connecting cylinder 100 due to excessive axial swing, which could cause jamming or deformation. This greatly improves the guiding effect and service life of the guide shroud 500.

[0028] How to use this utility model: First, it should be clarified that the guiding device involved in this utility model is mainly used for rapid guiding operations during the addition of powdered materials. This utility model takes the principle of solid powdered lubricant and the addition of additives as an example to explain its working principle and usage method in detail. The working principle is as follows: This device achieves anti-clogging and efficient feeding through a synergistic mechanism of "material impact - elastic vibration - directional flow - real-time monitoring". The principle of agglomeration dispersal: After the material falls from the storage box into the connecting cylinder 100, it first contacts the inverted conical guide shroud 500. The weight of the material and the impact force of falling cause the guide shroud 500 to move downward, driving the connecting plate 430 and the slider 420 to compress the elastic element 440 along the slide rail 410. When the elastic element 440 is compressed to its limit, the restoring elastic force pushes the slider 420, the connecting plate 430 and the guide shroud 500 to return to their original position, forming up-and-down reciprocating vibration, which disperses the agglomerated material into fine particles. Directional flow guidance principle: The conical structure of the flow guide shroud 500 guides the material to slide down at an angle, avoiding direct impact on the cylinder wall. At the same time, the slide rail 410 restricts the slider 420 to slide only up and down, eliminating the radial swing of the elastic element 440, ensuring stable vibration of the flow guide shroud 500 and improving the smoothness of feeding. Real-time monitoring principle: Operators can directly observe the material flow status, the effect of agglomeration and dispersal, and whether there is any potential for blockage through the transparent observation window 110. They can grasp the internal situation without disassembly, which facilitates timely handling of abnormalities. Structural stability principle: The cooperative structure of the double slide rail 410 and the connecting plate 430 effectively constrains the movement trajectory of the guide shield 500, preventing it from hitting the inner wall of the connecting cylinder 100. At the same time, the evenly distributed multiple sets of elastic support members 400 make the guide shield 500 subjected to balanced force, extending the service life of the components. The usage method is as follows: Device installation and commissioning: Connect the connecting cylinder 100 to the material storage tank outlet and the mixing tank inlet via flanges, ensuring reliable sealing; fix the feeding cylinder 200 to the connecting cylinder 100 via the fixing plate 300; install the slide rail 410, slider 420, connecting plate 430, and elastic element 440 on the outside of the feeding cylinder 200, and adjust the pre-compression of the elastic element 440; weld and fix the guide shroud 500 to the connecting plate 430, ensuring that the center line of the guide shroud 500 coincides with the center line of the feeding cylinder 200 and that the conical surface is not skewed; finally, install the transparent observation window 110 to check the sealing performance; Operation: Open the discharge valve of the material storage box. The material falls and impacts the guide shroud 500, causing reciprocating vibration. The shaken material slides along the conical surface of the guide shroud 500 into the feed cylinder 200, and then into the mixing tank. The operator monitors the material flow in real time through the observation window. If it is found that the agglomerates are not fully shaken or there are signs of blockage, the discharge rate can be temporarily increased to enhance the impact vibration, or the machine can be stopped for treatment. Maintenance: Weekly stop the machine to check the condition of the elastic component 440. If the spring deformation exceeds 15% or the elastic sheet cracks, replace it in time. Monthly clean the surface of the transparent observation window 110 to remove material stains and ensure clear observation. Quarterly check the wear of the slide rail 410 and slider 420 and apply lubricating oil (use Great Wall Lubricating Oil L-AN46 Total Loss System Oil) to reduce friction. Parameter adjustment: For high-viscosity and easily agglomerated materials, replace with a 60Si2Mn spring with a stiffer one (such as the TC100 type) to enhance the vibration force; for low-viscosity materials, use tin bronze elastic sheets to reduce vibration noise and adapt to different material characteristics.

[0029] This utility model can achieve efficient unblocking and dispersing of materials falling inside the connecting cylinder 100 by using the elastic support 400 in conjunction with the flow guide 500. It solves the problem that the traditional straight-cylinder feeding structure is prone to wall adhesion or "arch bridge" effect on the inner wall of the connecting cylinder 100 due to the lack of necessary flow guide structure, which leads to the accumulation of agglomerated materials and blockage of the feeding structure. Dealing with the blockage requires stopping the machine for disassembly, which is time-consuming and labor-intensive, and greatly reduces the efficiency of subsequent material mixing and production.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
