Description

Technical Field

[0001] This invention belongs to the field of lubricating powder production technology, specifically relating to a conveying device and conveying method for improving the production efficiency of lubricating powder. Background Technology

[0002] In the production process of lubricating powder, the conveying process is crucial, directly affecting production efficiency and product quality. Currently, tubular chain conveyors are widely used for conveying lubricating powder due to their advantages such as compact structure, small footprint, and ability to achieve multi-directional conveying.

[0003] However, existing tubular chain conveyors have some problems when conveying lubricating powder: at the discharge port, there is a gap between the pusher plate and the inner wall of the pipe, resulting in some lubricating powder residue, which not only affects the conveying efficiency, but may also cause material waste and pipe blockage; at the same time, the lubricating powder itself has a certain degree of stickiness and is easy to adhere to the pusher plate and the inner wall of the pipe, further aggravating the residue problem.

[0004] To address the aforementioned problems, those skilled in the art have made numerous attempts. For example, some have installed elastic sealing strips on the edges of the pusher plate to reduce gaps, but these strips are prone to wear after prolonged use, gradually reducing their sealing effectiveness. Others have used high-pressure airflow to periodically clean the pipelines, but this method requires production interruption, affecting the continuity of production. Therefore, developing a conveying device that can effectively reduce lubricant residue and improve conveying efficiency is of significant practical importance. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying device and method for improving the production efficiency of lubricating powder. It can use the impact force of instantaneously injected gas to quickly blow the lubricating powder off the conveyor, effectively reducing residue and improving conveying efficiency.

[0006] The specific technical solution adopted by this invention is as follows: A conveying device for improving the production efficiency of lubricating powder includes a feeding pipe and a discharging pipe. The discharging pipe is fixedly connected to the lower side of the side wall of the feeding pipe. The inner cavity of the feeding pipe is provided with multiple pusher plates, and a chain is assembled between the pusher plates. The side wall of each pusher plate is provided with a groove, and an elastic connecting component is provided in each groove. A blowing component is provided on the side wall of the pusher plate.

[0007] Furthermore, the elastic communication component includes a spring fixedly connected to the side wall of the groove, and a slider fixedly connected to the other end of the spring. The slider has a hollow structure, and an air inlet docking component is provided on the inner wall of the feeding pipe above the discharge pipe.

[0008] Furthermore, the air intake docking assembly includes a groove formed on the inner wall of the feeding pipe. The slider slides in the groove by the force of a spring. An air intake connector is fixedly connected to the side wall of the feeding pipe. The air intake connector communicates with the groove. When the slider moves to the lower side of the air intake connector, the air intake connector communicates with the inner cavity of the slider.

[0009] Furthermore, a first magnetic sheet is fixedly connected to the top surface of each slider, and a second magnetic sheet is fixedly connected to the side wall of the slide groove, with the first magnetic sheet and the second magnetic sheet attracting each other.

[0010] Furthermore, the blowing assembly includes a flow guide channel formed on the side wall of the groove, and an air storage chamber is formed on the left and right sides of the groove inside the pusher plate. A flow guide groove is formed on the bottom surface of the flow guide channel, and the flow guide groove is connected to the air storage chamber. A triangular flow guide block is fixedly connected to the bottom surface of the flow guide groove at the corresponding position of the flow guide channel. Furthermore, the pusher plate has several air outlets on its sidewalls, and four fan-shaped diaphragms are fixedly connected to the sidewalls of the air outlets. The four fan-shaped diaphragms form a circular structure in the air outlets, and the pusher plate is provided with a flow control component.

[0011] Furthermore, the flow control component includes two screw holes formed on the side wall of the pusher plate, the screw holes communicating with the flow guide grooves, and a bolt is internally threaded into one of the screw holes for intercepting the flow in one of the flow guide grooves.

[0012] Furthermore, a maintenance plate is movably connected to the side wall of the feeding pipe, and a locking element is provided on the side wall of the maintenance plate.

[0013] Furthermore, sealing rings are fitted on both sides of the groove on the sidewall of the pusher plate, and the sealing rings abut against the inner wall of the feeding tube.

[0014] Furthermore, the left and right sidewalls of the slide are inclined toward the side away from the slider.

[0015] A conveying method for a conveying device to improve the production efficiency of lubricating powder, the conveying method comprising the following steps: S1: The lubricating powder is filled between two adjacent pusher plates through the external feed hopper. As the external traction equipment drives, multiple pusher plates move in the feeding pipe. When the lubricating powder passes through the discharge pipe, it falls down by its own gravity to be discharged. S2: When the pusher plate approaches the discharge pipe during its movement, the slider enters the chute through the spring force, and at the same time the first magnetic piece and the second magnetic piece attract each other and continue to move along the chute. S3: When the inner cavity of the slider is connected to the air inlet connector, high-pressure gas is injected instantaneously using external equipment. The high-pressure gas enters the guide channel through the inner cavity and groove of the slider, and then fills the air storage chamber on the corresponding side through the guide groove 13. The pressure of the high-pressure gas is used to open the fan-shaped diaphragm, so that the airflow can quickly blow out the residual lubricating powder. S4: At the same time, the pusher plate continues to move, and the inclined surface of the chute makes the slider re-enter the groove for the pusher plate to discharge material once. Repeat the above steps to continuously discharge material.

[0016] The technical effects achieved by this invention are as follows: The present invention provides a conveying device and method for improving the production efficiency of lubricating powder. By instantaneously injecting gas, the lubricating powder on one side of the pusher plate is quickly blown off by the gas impact force. This method can accelerate the discharge speed of lubricating powder and reduce the residence time of lubricating powder at the discharge port, thereby improving the overall conveying efficiency.

[0017] The present invention provides a conveying device and method for improving the production efficiency of lubricating powder. Through the cooperation of the elastic connecting components and the setting of the magnetic surface, the sealing between the pusher plate and the inner wall of the feeding pipe is greatly enhanced, preventing lubricating powder from leaking and remaining in the gap. Furthermore, the instantaneous gas impact force can blow off the lubricating powder adhering to the pusher plate and the inner wall of the feeding pipe, further reducing the amount of residue.

[0020] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention. Example

[0021] like Figures 1-10 As shown, a conveying device for improving the production efficiency of lubricating powder includes a feeding pipe 1 and a discharge pipe 2. The discharge pipe 2 is fixedly connected to the lower side of the side wall of the feeding pipe 1. The inner cavity of the feeding pipe 1 is provided with multiple pusher plates 3. A chain 4 is assembled between the pusher plates 3. The side wall of each pusher plate 3 is provided with a groove 5. An elastic connecting component is provided in each groove 5. A blowing component is provided on the side wall of the pusher plate 3.

[0022] like Figure 5 , Figure 7 and Figure 8 As shown, the elastic connecting component includes a spring 6 fixedly connected to the side wall of the groove 5, and a slider 7 fixedly connected to the other end of the spring 6. The slider 7 has a hollow structure, and an air inlet docking component is provided on the inner wall of the feeding pipe 1 above the discharge pipe 2.

[0023] like Figure 7 As shown, the air inlet assembly includes a groove 8 formed on the inner wall of the feed pipe 1. The slider 7 slides within the groove 8 under the elastic force of a spring 6. The left and right sidewalls of the groove 8 are inclined towards the side away from the slider 7. The inclined design facilitates the slider 7 entering and sliding out of the groove 8. An air inlet connector 9 is fixedly connected to the sidewall of the feed pipe 1. The air inlet connector 9 communicates with the groove 8. When the slider 7 moves to the lower side of the air inlet connector 9, the air inlet connector 9 communicates with the inner cavity of the slider 7.

[0024] Specifically, spring 6 is made of piano wire, which has excellent elastic recovery performance and fatigue life, and its stiffness coefficient is set at 60-80 N / m. When the pusher plate 3 moves to the position of the slide groove 8, the elastic force of spring 6 can accurately push the slider 7 into the slide groove 8, ensuring a tight fit between the slider 7 and the slide groove 8. The slider 7 is designed with a hollow structure, which not only reduces its own weight, but also serves as a channel for gas flow, allowing the gas injected by the air inlet connector 9 to smoothly enter the blowing assembly inside the pusher plate 3.

[0025] In addition, the outer wall of the slider 7 is coated with polytetrafluoroethylene, with a friction coefficient as low as 0.04, which reduces the sliding friction between the slider and the groove 8, reduces power loss, and improves the wear resistance of the slider 7, extending its service life to more than 3 times that of traditional metal sliders.

[0026] like Figure 7 As shown, a first magnetic sheet 10 is fixedly connected to the top surface of the slider 7, and a second magnetic sheet 11 is fixedly connected to the side wall of the slide groove 8. The first magnetic sheet 10 and the second magnetic sheet 11 attract each other.

[0027] Specifically, both the first magnetic sheet 10 and the second magnetic sheet 11 are made of neodymium iron boron strong magnetic material with a magnetic flux density of 1.2T. The attraction between them enhances the tightness of the fit between the slider 7 and the groove 8. When the slider 7 enters the groove 8 under the action of the spring 6, the magnetic attraction further compensates for the insufficient spring force, making the slider 7 and the side wall of the groove 8 form a surface contact. The sealing gap is controlled within 0.05mm, effectively preventing gas leakage from the gap during the flow process and ensuring the stability of gas pressure. At the same time, the magnetic attraction can buffer the collision between the slider 7 and the groove 8, reduce mechanical wear, and reduce operating noise.

[0028] like Figure 5 and Figure 9 As shown, the blowing assembly includes a flow channel 12 opened on the side wall of the groove 5. The pusher plate 3 has air storage chambers 14 opened on the left and right sides of the groove 5 respectively. The bottom surface of the flow channel 12 has a flow groove 13, which is connected to the air storage chamber 14. A triangular flow guide block 17 is fixedly connected to the bottom surface of the flow groove 13 at the corresponding position of the flow channel 12. The pusher plate 3 has several air outlets 15 on its side wall. Four fan-shaped diaphragms 16 are fixedly connected to the side wall of the air outlets 15. The four fan-shaped diaphragms 16 form a circular structure in the air outlets 15. The structure principle of the fan-shaped diaphragms 16 is similar to that of the cap of the existing beverage bottle (scream). The pusher plate 3 is equipped with a flow control component on its side wall.

[0029] The chute 8 is precisely positioned to align with the upper side of the discharge pipe 2. When the pusher plate 3 moves to the vicinity of the discharge pipe 2, the slider 7 enters the chute 8, connecting with the air inlet connector 9. The chute 8 is 10-15mm deep and 0.5mm wider than the slider 7, ensuring smooth sliding of the slider 7 while guiding it through the sidewalls of the chute 8 to prevent deviation during movement. The air inlet connector 9 is made of brass with a chrome-plated surface, providing excellent airtightness and corrosion resistance. Its connection to the feed pipe 1 uses a threaded sealing structure, combined with Teflon tape sealing, to ensure no gas leakage. The inner diameter of the air inlet connector 9 is 8-12mm, meeting the instantaneous gas flow requirements, allowing gas to quickly fill the hollow cavity of the slider 7 within 0.5 seconds. Furthermore, the cross-section of the guide channel 12 can be funnel-shaped, with the inlet diameter larger than the outlet diameter, which can accelerate the gas and increase the flow velocity of the gas entering the guide groove 13. The triangular guide block 17 is made of polyoxymethylene, and its angle is designed to be 60 degrees. It can evenly distribute the gas in the guide channel 12 to the guide groove 13, avoiding energy loss caused by the formation of eddies in the guide channel 12. Moreover, the gas pressure in the gas storage chamber 14 is stabilized at 0.3-0.5 MPa, providing a continuous gas impact force for the outlet 15.

[0030] Furthermore, the structure and distribution of the vent 15 are not limited to this design. The axis of the vent 15 can also be angled at 45 degrees to the surface of the pusher plate 3 and oriented towards the discharge pipe 2. This inclined design ensures that the gas injection direction aligns with the lubricating powder discharge direction, maximizing the utilization of the gas impact force. The four fan-shaped diaphragms 16 are made of silicone rubber, possessing excellent elasticity and aging resistance. When no gas is emitted, the diaphragms are tightly fitted to form a sealed structure, preventing lubricating powder from entering the vent 15 and causing blockage. When the gas pressure reaches 0.2 MPa, the diaphragms are pushed open to form a 5-8 mm diameter injection port. After the gas is ejected, the diaphragms automatically reset, forming a seal again, effectively preventing the reverse entry of lubricating powder.

[0031] like Figure 2 As shown, a maintenance plate 20 is movably connected to the side wall of the feed pipe 1, and a locking element is provided on the side wall of the maintenance plate 20. The maintenance plate 20 is connected to the feed pipe 1 via a hinge, and the opening angle can reach 180 degrees, providing ample operating space for internal maintenance of the feed pipe 1 and facilitating the sealing of the guide groove 13 by the control bolt 19. The locking element adopts a snap-fit ​​structure, with an operating force of less than 50N, enabling quick locking and opening of the maintenance plate 20; a nitrile rubber sealing gasket with a compression of 20% is provided on the contact surface between the maintenance plate 20 and the feed pipe 1 to ensure no lubricating powder leakage during equipment operation.

[0032] like Figure 8As shown, sealing rings 21 are installed on both sides of the sidewall of the pusher plate 3 located in the groove 5, and the sealing rings 21 abut against the inner wall of the feed pipe 1. The sealing rings 21 are made of fluororubber, which has the characteristics of high and low temperature resistance and chemical corrosion resistance, and can adapt to the temperature changes in the lubricating powder production environment (-20℃ to 120℃). The cross-section of the sealing rings 21 has a lip-shaped structure, which forms a line seal when in contact with the inner wall of the feed pipe 1, with a contact pressure of up to 0.6MPa. During the movement of the pusher plate 3, it can effectively scrape off the lubricating powder adhering to the inner wall of the feed pipe 1, further reducing residue. Example

[0033] Based on Example 1, this example specifically discloses the blowing direction of high-pressure gas on the pusher plate 3: like Figure 6 , Figure 9 and Figure 10 As shown, the flow control assembly includes two screw holes 18 formed on the side wall of the pusher plate 3. The screw holes 18 are connected to the flow guide groove 13. One of the screw holes 18 is internally threaded with a bolt 19 for cutting off the flow in one of the flow guide grooves 13.

[0034] The design connecting the screw hole 18 and the guide groove 13 allows the operator to cut off one of the guide grooves 13 via the bolt 19, thus closing the vent 15 on one side. This design can adapt to the conveying needs of lubricating powders with different properties: for lubricating powders with low viscosity, both vents 15 can be opened to improve blowing efficiency; for lubricating powders with high viscosity, one vent 15 can be closed, concentrating the gas pressure to powerfully blow away the other side, ensuring that residual lubricating powder is completely removed. The air outlet direction can also be adjusted according to the conveying requirements of the lubricating powder. The bolt 19 adopts an internal hexagonal structure, combined with a nitrile rubber sealing ring, which can ensure the sealing during cutoff and facilitate quick adjustment without the need for special tools. Example

[0035] A conveying method for a conveying device to improve the production efficiency of lubricating powder, the conveying method comprising the following steps: S1: The lubricating powder is filled between two adjacent pusher plates 3 through the external feed hopper. As the external traction equipment drives, multiple pusher plates 3 move in the feed pipe 1. When the lubricating powder passes through the discharge pipe 2, it falls down by its own gravity to be discharged. S2: When the pusher plate 3 approaches the discharge pipe 2 during its movement, the slider 7 enters the slide groove 8 by the elastic force of the spring 6. At the same time, the first magnetic sheet 10 and the second magnetic sheet 11 attract each other and continue to move along the slide groove 8. S3: When the inner cavity of the slider 7 is connected to the air inlet connector 9, high-pressure gas is injected instantaneously using external equipment. The high-pressure gas enters the guide channel 12 through the inner cavity of the slider 7 and the groove 5, and then fills the air storage chamber 14 on the corresponding side through the guide groove 13. The pressure of the high-pressure gas is used to open the fan-shaped diaphragm 16, so that the airflow can quickly blow out the residual lubricating powder. S4: At the same time, the pusher plate 3 continues to move, and the inclined surface of the slide 8 makes the slider 7 re-enter the groove 5 for one discharge of the pusher plate 3. The above steps are repeated to continuously discharge the material.

[0036] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
